Description

 Technical Overview Description Of Operation

- WMV 'TULZ' Surface Coating Equipment

Note: The video posted on YouTube by Riley Industries Ltd is very useful and I recommend that the description below is read in conjunction with the video and process layout drawing in 4. Appendix 1. Reference: https://www.youtube.com/watch?v=yQADfHoc9w8

1. Process Module Overview

The WMV 'TULZ' plant consists of 7 stations, whilst standing at the HMI control station looking from left to right these being:-

1. Finished Processed Parts Unloading (Ref Items 7 & 8 Appendix 1)

2. Used Basket Washing (Ref Items 9 & 10 Appendix 1)

3. Pre-Processed Parts Loading Carriage and Part Loading Chute (Ref Items 1, 2 & 3 Appendix 1)

4. Surface Coated Parts Dryer (usually 10 min cycle time) (Ref Item(s) 6 Appendix 1)

5. Surface Coated Parts Dryer (usually 10 min cycle time) (exactly the same as 4.)

6. Basket Into 'TULZ' Tower Transfer Arm

7. 'TULZ' Tower (Approximately 5 min cycle time) (Ref Item 4 Appendix 1)

All of these stations are serviced by the, indexed for position, overhead transporter carriage. There are 5-off baskets in the system, and all should be at some point in the cycle to ensure efficient processing. There is no 'parking' station in the system for an unused or spare basket.


2. Process Description

2.1 The empty basket is lowered by the overhead transport carriage ('transporter') into the oscillating, floor mounted, in-feed carriage. Parts are manually loaded by the operator into the basket through the aligned loading access. The grid covering the loading access is interlocked to ensure the operator cannot easily access the basket until into position and basket rotation has stopped.

2.2 When the basket has been loaded to the correct pre-determined level for the parts being coated the grid is lowered and the cycle start button pressed.

2.3 The motorised, floor mounted, transport carriage will then move to centre line with the overhead transport carriage, which will lower the grab finger frame to the basket rim, close around the rim and elevate the basket until the basket bottom rim is around head height. Sensors are fitted to ensure full location of the grab fingers on the basket rim.

2.4 Once elevated, the filled basket will be transported along the overhead gantry to align with the 'TULZ' tower in-feed arm, where the loaded basket is lowered onto the location cradle on the transfer arm. The overhead transporter grab finger frame will then raise to clear the basket, allowing the transfer arm a clear arc into the 'TULZ' tower. The side access door of the 'TULZ' tower will raise automatically to enable a clear path for the transfer arm with loaded basket.

2.5 The transfer arm raises to engage the upper rim of the basket to the grab fingers of the driven head within the 'TULZ' tower.

2.6 The transfer arm retracts to the parked position, the side access door of the 'TULZ' tower lowers, preventing excessive splashing of liquid coating medium outside of the tower.

2.7 The large volume bath containing the specified liquid surface coating medium will raise to fully dip the loaded basket. The driven head will then oscillate to ensure an even coat of the liquid coating medium, especially for tubular parts. When the submerged basket oscillation is complete the bath will lower slightly enable the driven head and basket to tilt and then spin at slow speed enabling excess liquid coating medium to return to the bath, preventing excess drag-out.

2.8 When the dipping cycle has completed the bath will fully lower to floor level, the side access door of the 'TULZ' tower will raise and the transfer arm will swing through its operating arc to position the cradle below the basket, raise to locate the grab fingers onto the lower rim of the basket, then swing back through the operating arc to the overhead transporter centre line.

2.9 The overhead transporter will move into position on-centre to the now dipped basket. It will raise the dipped basket from the transfer arm cradle and transport along to a vacant drying station where the basket is lowered into the drying unit, the overhead transporter moves away to enable the drying station lid to lower and close. Hot air generated from two heating elements is then blown into the chamber during the cycle. The whole drying unit module tilts over in an arc to ensure the parts tumble within the internally rotating drum, ensuring even drying of the parts. Once the, usually, 10 minute cycle has completed the module returns to the vertical position and the lid opens.

2.10 The overhead carriage will motor accurately into position, the frame will lower and elevate the basket to height. The transporter will traverse along to the extreme end to the location of the unloading station. The basket is then lowered onto the cradle and sensored grab fingers grip the lower rim of the basket.

2.11 The basket will not empty until the operator activates the cycle by push button. Once activated the basket will rotate to even the internal load. The rotation stops, the holding cradle will then rotate horizontally to tip the product to the vibrating chute below.

2.12 The vibratory chute traverses the parts, through diverters to assist with even flow, into receiving work tins. Control of the vibratory exit chute is by the operator to prevent overfilling or spillage of the receiving work tins.

2.13 Once emptying of the basket is completed the overhead transporter moves to position to retrieve the basket from the cradle and transfer the dirty basket to the washing station. The used basket is lowered into the internal cradle, the overhead transporter moves away, enabling the lid the close and high pressure, heated wash solution, is sprayed on all surfaces, internal and externally, of the rotating basket. This will ensure the perforations of the basket do not clog with applied, baked, surface medium. This ensures efficient application during every cycle of the surface coating medium. The wash solution is returned to the heated wash solution reservoir via a pumped system.

2.14 The wash solution holding reservoir has an internal weir system to contain the build up of solids within the reservoir. This assists with an extended life of the wash solution.


3. Peripheral Information

3.1 The control of the process within the 'TULZ' tower is controllable in seconds for the dipping time, basket spinning duration, direction of spin, angle of the basket etc. Usually this process is approximately a 5 minute duration.

3.2 The drying process is usually a 10 minute process, hence the need for 2 drying stations. The system will place 1 loaded basket after coating into 1 dryer, then at the following basket will be placed into the second dryer. At this point, if the process is being run efficiently, the coated, dried product is being unloaded whilst the 2 dryers are both running together for a short period.

3.3 Following the unload, the empty basket is placed into the basket wash station prior to placement into the product loading oscillating carriage. Then the process cycle starts again with parts loading into the basket.

3.4 Different types of liquid coating medium can be used in the separate large capacity baths placed into the 'TULZ' tower. The baths are on wheels. Access to change the baths is by a large side door in the 'TULZ' tower.

3.5 The baths are connected to the system via a plug allowing the system to read the bath identification, 'Bath 1', 'Bath 2'

3.6 The system is then programmed via the HMI panel according to the coating medium requirement for all of the required parameters, such as dipping time, spin speed, drying time, solid parts, tubular parts, etc.

3.7 The basket wash station is also programmable for duration.

3.8 Location of this equipment ideally requires clear fork truck access to the end face at the 'unloading station' end. This allows the heavy baskets to be removed / replaced for periodic replacement or maintenance in the system.
