1.0 Introduction

The TQC Sheen automatic panel sprayers have been designed to remove inconsistencies in the application of wet sprayed coating materials when applied by experienced operators using a hand held guns.

The machines are equipped with a range of adjustments to enable the operator to determine the optimum settings for consistency in the application of a wide range of liquid coating materials. Subsequent sample batches can be applied using the same settings.

Consistency in coating application is absolutely essential for subsequent evaluation of visual properties including colour, gloss, opacity and general appearance, also for the physical properties including thickness, sagging, levelling and adhesion.

Evaluation of these parameters is particularly important when applying high performance coatings such as metallic, pearlescent paints and specialist effect coatings.

The elimination of variabilities at the application stage enables any discrepancies in the applied coatings to be attributable to differences in formulation or processing before the application of the coating material.

2.0 Panel Sprayer Features • Easy to operate controls.

• All functions and movements are operated by compressed air.

• Adjustable for the 2 spray guns to panel distance, gun travel speed and spray pressure.

• Adjustable panel lift 40 & 50mm settings for SH0590, this assists overspray of the previous pass of

the spray guns.

• SH0581 model benefits customer specified panel lift increments, from 10 to 500mm. (smaller

increments produces greater overspray of previous pass of the spray guns.

(lift increments to be specified at the time of ordering)

• Flash off timer, to enable optimum setting of rest period between each coating.

• Framework and panels are constructed from stainless steel, making for easy cleaning.

• Magnetic Panel holders. (Vacuum holders for non-metallic panels if required, available at the time or

8.0 Machine Description

8.1 Panel Holder An anodised aluminium frame fitted with magnets to retain steel test sample panels. The holder is easily removed for cleaning by loosening the socket cap screw located at the base and pulling the holder upwards from the support bar. 8.2 Brush Seals These seals protect the gun traversing cylinder, panel lift cylinder and the components within the sprayer from accidental material spillage and over spray.

8.3 Top Panel This panel is manufactured from stainless steel to facilitate cleaning. A raised lip around the base of the panel holder and the gun post slot serves to prevent material accidentally entering the sprayer.

8.4 Control Panel Stainless steel with all controls and indicator identifications chemically etched.

8.5 Cover Panel All made of stainless steel and fitted with quick release fasteners to allow easy access for service and maintenance.

8.6 Air Input Connector A ½” BSP bulkhead connector is located on the lower right hand side of machine. In addition, a ½” BSP X 12mm straight Speedfit coupling is provided as an option. If a Speedfit coupling is used then the 12mm nylon pipe is connected by simply pushing pipe into connector. To release pipe from Speedfit hold down collet and pull out pipe.

8.7 Castors Four swivelling castors are fitted to the unit, making it very easy to move the sprayer from one location to another. The two front castors are fitted with brakes which must always be locked when the machine is in operation in order to prevent movement.

8.8 Handles A handle is fitted on each side of the sprayer, making it easy to manoeuvre.

8.9 Air Supply The air supply capacity to the Sprayers must be clean, dry and filtered.

8

9.0 Control Panel Functions

9.1 Manual/Off/Auto Switch This switch provides control of 3 functions. With the switch set to Off the cycle cannot be started, if it is switched to Off position during the auto cycle, the current spray cycle will complete then come to rest.

Manual provides main air to all manual function switches and when operated it activates emergency stop to prevent start up without reset being actioned. Switching to Auto enables start of cycle.

9.2 Auto/Manual Spray This provides three conditions for spraying:

i Manual, this offers manual control of gun 1 or 2 for cleaning and setting purchases

ii Auto with the switch in mid position the full spray width is programmed for auto spray cycle.

iii Auto, this provides reduced spray width of particular use in spraying 1 panel or standard width.

9.3 Gun 1, Gun 2 This switch provides selection to gun 1 or gun 2

Gun 1 Auto spray cycle will control gun 1 only, as manual spray.

Gun 2 Auto spray cycle will control gun 2 only as manual spray.

9.4 Spray Pressure – Gauge The gauge indicates the air pressure of the main supply to the spray guns. 9.5 Spray Pressure Regulator Determines the pressure of the main air supplied to spray guns, and is used in conjunction with gauge 9.4 to prevent accidental alteration the regulator control knob cannot be turned unless it is first pulled out slightly from the control panel. The regulator is then turned clockwise to increase pressure or anti-clockwise to decrease pressure. When pressure is set push knob toward panel to lock.

9

9.6 Lift Select SH0590 This model provides a choice of 40mm or 50mm lift increments of the panel holder. SH0581 model has the customer specified lift increments (10 to 500mm) adjust accordingly. NOTE: Maximum lift is 9 raises at 50mm increments, and 11 raises at 40mm increments for the SH0586 model, for SH0582 version, the lift increments is dependent on the customer specification. (range from 10mm to 500mm increments) NOTE: This should not be changed once the cycle has been started.

9.7 Number of Coats Counters This counter determines the number of times the spray gun repeats a series of passes across the test panels to complete one coat. To set the counter, hold down the white button and push in the ‘1s’ ‘10s’ button repeatedly until the required value is displayed, then release the white button. 9.8 Flash-Off Timers Using this timer provides a delay of up to 10 minutes between the applications of each coat. To set the timer, simply turn the knob to the desired delay time. If several different flash off times are required during multi-coat spraying, it is possible to change timer setting during spraying sequence. It is also possible to shorten time delay while timer is operating, even turning dial to zero to start next cycle. However it is not possible to increase time value while timer is operating.

9.9 Number of Passes Counter This control determines the number of times the guns will travel across the face of the test panels to complete one coat. The panels are raised between each pass to ensure full coverage of test panel. To set the counter, hold down the white button and push the far right black button for a single digits (0-9) repeat for 10‘s pressing down second from the right black button.

9.10 Traverse Speed Control This function determines the speed at which the gun travels across the face of the test panels. The speed is changed by rotating the dial clockwise to reduce sped, anti-clockwise to increase speed. The dial graduations enable the operator to make a note of the setting, note the graduations do not represent any particular unit of speed.

Important. If the incoming air falls this will affect the traverse speed, the controller would require adjustment.

9.11 Manual Traverse The switch operates the manual control of the traverse cylinder and is useful when setting or testing spray guns central to the panels.

9.12 Start Button When the sprayer has been programmed and the spray guns and test panels set, press the button to commence the spraying sequence. 9.13 Raise/reset Button This has dual functions, and is only operable by engaging the emergency stop. The switch is spring loaded to the centre position therefore needs to be held for as long as a signal is required. Reset: Will reset all functions to the start conditions. Raise: Permits the operator to raise the panel holder to a convenient position for loading/unloading panels (When functional in the manual mode) . 9.14 Emergency Stop Pressing this button while the sprayer is in operation will stop cycle and the spray guns immediately This sprayer will not function again until the reset has been actioned. It is advisable to reset the machine after use of emergency stop with 20 minutes.

10 Installation

10.1 Main Air Supply Allow a suitable period of time for the Sprayer to attain ambient conditions (temperature and humidity)

Clean, dry air, pressure not to exceed 1Mpa (1000kPa) 10 bar (150psi)

Volume capacity approximately 35scfm

Connection main air supply to input bulkhead using 12mm tubing ½” hose line. When using the Speedfit

connector ensure 12mm pipe has a clean square cut and is pushed firmly into collet of fitting.

When using ½” BSP connection make sure that there are no restrictions introduced from any smaller size

additional couplings.

10.2 Earth Wire Connection An earth stud has been provided in order to fit an earthing cable, this is good practice and particularly important in view of the possibility of static electricity. The stud is located on rear right hand castor mounting plate, accessed through right hand side panel.

11

11 Panel Holder Preparation

Before placing test panels on the panel holder, it is advisable to mask the framework and any magnets (or vacuum holders) that are not in use. This greatly reduces the amount of time and effort required to clean the holder after the machine has been used. The panel holder can be removed from the support bar by loosening the wing nut at the base of the support bar. 11.1 Test Panels Panels must be flat and free from contamination (degreased, no finger prints) to ensure a consistent application of the coating materials. (Also see para 18.0 Associated products) Important Test sample panels should be positioned to the holder in such a way that they are supported at each of the four corners to ensure that the surface is presented flat and perpendicular to the traverse of the spray gun. (The image below refers)

12.0 Spray Gun Preparation

12.1 Gun Post Assembly The SH0590 & SH0581 panel sprayers are designed for twin guns use allowing the spray gun to be mounted central to the post. The height of the spray gun is not adjustable, its position provides uniform coverage for maximum panel lift. The horizontal distance between gun and panel is adjustable by releasing locking screw and moving plate left or right. If this is insufficient then plate can be turned through 180°.

12.2 Airlines to Spray Guns Two colour coded lines supply air to the guns. The large green line carries mains air used to propel the paint from the gun. The smaller red line activates the gun trigger, switching the gun on or off as it receives the signal from the machine.

12

13.0 Operating Instructions

13.1 Instructions Ensure that you have read and understood all sections of this manual, particular attention to be drawn to the control panel operation section, before operating the panel sprayer. 13.2 Air Supply Check that the mains air supply is connected at the machine bulkhead, supply is turned on and no air leaks are present at the connection. Any air leaks must be dealt with before proceeding to operate the sprayer. 13.3 Isolator Valve Remove the right-hand cover panel, check the isolator valve is set to on position and that the machine pressure is set to no more than 7.5 bar (100psi) 13.4 Control Panel Set the control panel “Air On/Off” switch to On position, if the spray guns operates immediately check “manual spray” switch is set to the “Off” position and operate reset. If the panel holder and gun are not in their starting positions (Panel Holder fully in the down position, gun post set to end of the left-hand position of travel) press the emergency stop button then hold reset switch until they return. Ensure nothing is obstructing the traverse/gun post and keep clear of the gun post when operating reset. 13.5 Spray Gun Setting Set the guns distance between the guns and the panel holder. It is possible to position the gun central to the panel holder by first turning the traverse speed control to a low figure, pressure the emergency stop button then operate manual left/right until the gun is in front of the panel holder. If this procedure is followed reset must be actioned prior to start, machine will only start from starting position as previously mentioned. Fill both gun reservoirs with the previously prepared sample material (paint, varnish etc.) Using the “Manual Spray switch position check the gun pressure is correct by noting the gauge reading on the control panel, adjust as necessary using the pressure regulator gauge.

13

With the manual spray switch “ON” check spray gun settings for optimum fluid and air delivery to achieve the required atomisation, next switch to “Off”. NOTE. THIS CAN ONLY BE OPERATED FOLLOWING EMERGENCY STOP. 13.6 Traverse Speed Select the required traverse speed. 13.7 Panel Lift Select the lift increment switch between 40 & 50 mm on the SH0586 and customer defined settings for the SH0582 model. 13.8 Coats Counter Set the number of coats as required for each gun (Note the panel lift has been pre determined), see above) 13.9 Flash-off Timers Set the Flash-Off Timers 0 – 10 minutes. 13.10 Test Panels Place the test panels onto the holder checking first that the holder is masked to prevent overspray and assist in subsequent cleaning. 13.11 Start Button Prior to starting check the following:

• Select the required traverse speed • Set the lift increments. (40 -50 on the SH590 model, customer specification from 10 – 500 on

SH0581 model) • Set the number of coats required. • Set the number of passes required. • Select gun 1 or gun 2 or auto 1 + 2. • Set the Flash-off Timers for both guns 1 & 2. • Place the test panels on to the Panel Holder checking first that the holder is secured and suitably

masked to facilitate cleaning. • Press the start button. • Monitor the spraying sequence and settings, changing flash-off timers and traverse speed to

achieve optimum results. • Before starting the next sequence remember to check the material levels in the gun reservoirs and

that the status of the switches, timers, counters are correctly set. • Press the start button to operate the machine, if necessary monitor the sequence, changing flash-off

timers and traverse speed as required. • When the sequence is complete remember to check material levels in the guns reservoir and that

status switches, timer and counter are all set is required. • Press emergency stop switch then reset before starting another cycle.

17.0 Associated Products

To contribute towards obtaining consistent film application we recommend the following products:

17.1 Test Panels We offer a range of steel and aluminium panels for the Sprayers to ensure constancy of the surfaces for film application.

17.2 Wet film thickness gauges To obtain the optimum Panel Sprayer settings (speed of application, panel lift, gun settings.) these gauges offer a quick method of checking the wet film thickness at the application stage. This is partially important when in determining the % loss between wet and subsequent dry film thickness.

17.3 Further information on Accessories For further information on these products, also for products for use after the coating film has cured. (Dry film Thickness Gauges, Gloss, Opacity and Colour Meters) visit our website www.tqcsheen.com

16

18.0 Maintenance

18.1 Safety Any work carried out on mechanical parts within the machine frame should be performed with caution. Please note that cover panels are NOT safety interlocked so the system should be isolated from mains air pressure using the ISOLATION SWITCH (inside right hand side panel).

To operate, press the cap down and this will vent the system.

NOTE: To reset isolation switch press orange button inside cap.

18.2 Compressed Air Filter The filter is intended to remove moisture from the mains air supply. As water collects in the bowl of the filter it is necessary to regularly check the filter bowl to ensure that water does not accumulate to such an extent that it could enter the control system. This may be caused by a particularly damp supply or a sudden surge in the moisture content. To manually release accumulated water, the water release valve at the base of the bowl should be unscrewed one or two turns. The valve should never be fully unscrewed. Tighten the valve again after the water has drained.

18.3 Traverse Assembly WARNING: In the event of any adjustment being made, main air must be disconnected.

With traverse cylinder mounted onto frame and gun post assembly fitted carryout following checks:

1. Check for free and smooth movement in both directions – Set Speed controller to a low figure e.g. 10-20. Press emergency stop any operate manual left/right switch.

2. Check for no lateral movement of carriage by pushing and pulling gun post.

The carriage slide system can be adjusted if necessary as detailed below.

To adjust the carriage slide loosen grub screw, these lock adjusting screws.

If carriage is loose:

1. Slacken screws “A”. 2. Turn screws “B” clockwise in small increments ensuring even adjustment. 3. Tighten screws ”A”.

Reverse if carriage is too tight.

17

18.4 General Inspection • Check for air leaks. • Inspect brushes for wear. • Check panel lift assembly is secure. • Check the security of the earth stud connection.

18.5 Fault finding – Skills Requirements The level of fault finding is limited to checking that the main functions are operating correctly and conducting elementary level inspection and checking.

Pneumatics Engineer For full investigation of finding faults the skills level required is that of a trained pneumatics engineer this is outside the general scope of the customer’s operators and engineers, should the occasion arise when a full investigation is required please contact our Service Dept. who will be able to advise accordingly.

The nature of the fault finding listed in this manual is first stage investigation, this will enable the local engineer to check that the operator settings are functioning correctly and can relay the information to TQCSheen Service engineers.

18.6 Pre-Fault Finding Checks Prior to fault finding check the following:

• Main air supply on at 6 – 6.5 bar (90 to 100 psi). • Counters are reset and pre-set value is not less than 1. • Manual/auto switch is set to AUTO. • Check for air leaks. (Supply line, couplings etc.)

In the event of a fault occurring reset the sprayer to its start condition in the following manner: 1) Press the emergency stop 2) Switch the reset on and hold until both LIFT and TRAVERSE cylinders are returned to their start

positions.

18

18.7 Panel Sprayer Fault Finding Machine will not start when START button is pressed:

• Check the air supply to the machine is supplying approximately 6.5 bar (100PSI) • Check the machine is turned on • Check the machine is reset fully • Check the lift cylinder carriage is fully retracted and is sitting on limit switch. If carriage is on the

switch then the switch could be faulty 18.8 Traverse faults When the start button is pressed, the traverse cylinder should go from left to right.

• If the cylinder goes from left to right, sprays, and then returns straight away then check the counter is set up. Check the counter is not giving a continuous output by removing the A output pipe from the coats counter, and checking that air is coming from the counter. If air is coming from the output, try resetting the machine and also press the manual reset button on the front of the counter. If the fault still occurs, a new counter will be required.

• If the machine traverses from left to right then returns straight away then lifts then repeats this until it reaches the number of passes then returns to the start position, this is usually caused by one of the logic elements on the logic module become faulty. This will require changing and the services of an service engineer.

• If the traverse travels one way fast and back the other way slow, the cylinder seals could be worn. To check this, open the door on the machine and listen for air leaks from the cylinder. Also, the internal seals could be worn. To check these turn the air supply off to the machine and disconnect the pipes to the cylinder. Apply an air supply to one end of the cylinder (turn air on slowly), the cylinder should then traverse to the other end if air still comes out of the cylinder once it has reached the end then the seals are worn. Repeat for the other end of the cylinder.

18.9 Machine Stops in Mid Cycle (Lift Cylinder Faults) If the machine stops during the cycle check:

1) The speed of the lift cylinder is not too quick when it lifts, this can cause the magnetic reed switches on the carriage to miss the contacts, which will in turn stop the machine. To adjust the speed of the cylinder there is a flow restrictor at the top and the bottom of the cylinder which when adjusted will speed up or slow down the cylinder.

2) Check the magnetic switches are set up properly, e.g. the distance between the switch and the switch contact (gap should be between 1mm/2mm).

3) Check the switches are working (when the switch gives an output, the indicator button should be sticking out. If not, replace the switch.

4) If the cylinder is not lifting try adjusting the flow restrictors on the cylinder, and adjust the cylinder carriage by loosening the ten adjusting screws on the side of the carriage.
