Presentation of designs to YKK Team leader : Poon San On (Zen) Team members: Lee Man Kit(Jason) Kong Yau Choi(Eddie) Mak Fu Shun(Vincent) Wong Ching Pong (Richard)
Introduction Founded in 1966, YKK Hong Kong Limited is as a subsidiary of YKK Corporation. The company is one of the biggest corporation in producing and selling zippers.
We are glad to do the manufacturing project working under YKK. Today, we present the designs of adhesive paper tapping machine.
For the different size of the box, some parts can be adjusted.
Advantages: The mechanism is simple. The cost is relatively low. The box need not to stay in one place and can move through all the process. Disadvantage: The machine is in L-shape, a large area may be needed.
Operation 1 When the box arrives at the set position, the belt will stop.( There are some sensors to detect the box’s position.) Two gears will start to move in x-direction through the “rack and pinion”. Since there are drafts to connect everything, two adhesive papers are moving in x-direction too.
Operation 2 At the same time, there are a plastic smoother and a brush following it. So the adhesive paper can be sticked on the box. By installing a timer on the machine, the belt will move again when the process is finished.
Pros and Cons Advantages Low in cost User-friendly Disadvantages Big in size (occupied large area) Slow
Designed by Zen 2 stages for sticking the adhesive papers. 1 stage for compressing the adhesive papers against the box. 8 pneumatics to adjust position. 3 sensors with timers to stop the box.
Step 3: The bar is extended with Pneumatic to absorb the adhesive paper using the absorber! Step 1: The box is moved by rollers, there is one sensor to stop there is one sensor to stop the roller from moving when arriving at the mechanism. Step 2: The four pneumatics extend to push the box in the middle position!
Step 4: The Absorber absorbs the adhesive paper and pulls it out to the one end of the box then stop!
Step 5: The Absorber absorbs the adhesive paper and Pulls it out to the one end of the box then stop! Step 6: The cutter is extended to cut off the adhesive paper
Step 7: The Absorber retreats, and return to the beginning position! Step 8: The 4 pneumatics and the cutter retreat! Step 9: The rollers will start moving the box after a few seconds using a timer.
Step 10: The box is moved to the next stage for front attachment! and the absorber return to original position! Step 11: the Front attachment is the same as the Back attachment!
Step 12: The plate will push the two adhesive papers against the box, and make them stick together smoothly and firmly! The plate can rotate 90 degree to compress the latter adhesive paper.
Operation 234 Box stops at 2 Start to put adhesive paper on the box Box stops at 3 Make sure the adhesive paper stick on the box Also, at 2, the adhesive paper start to put on the box Box stops at 4, then 3 will run again its operation
Sticking part cylinder Paste the adhesive paper on the box at right position (operating by rack and pinion) After that, the adhesive paper will reture the starting position by rack and pinion, to the ready state for next side
Pressing part To make sure that the adhesive paper has stricked on the box. Load the “T” shape brush down to the box.
Adhesive paper roller Adhesive paper Gear connected to rack
Advantages Easy to assemble: Few components to be added in the system Effenient: Two adhesive paper can be put for two boxes at the same by two structures Space saving : only one conveyor is required
Disadvantages The “T” shape brush and lots of sensors will be used to detect the positions of the boxes Time costly: The boxes have to be stopped for the whole operation
