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.

Adhesive Machine Design 1

By Vincent

Once the box press the senor, cylinder will push the box to the second conveyer. Therefore, the box can change the direction.

Sensor

Then the box will pass through the sticking 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.

brush

smoother

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

AdvantagesLow in cost User-friendly

DisadvantagesBig 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: Step 1: The box is moved by rollers,The box is moved by rollers, there is one sensor to stop there is one sensor to stop the roller from movingthe roller from movingwhen arriving at the mechanismwhen arriving at the mechanism..

Step 2:Step 2:The four pneumaticsThe four pneumaticsextend to push the box extend to push the box in the middle position!in the middle position!

Step 4:

The Absorber absorbs the adhesive paperand pulls it out to the one end of the box then stop!

Step 5:The Absorber absorbsthe adhesive paper and Pulls it out to the one end of the box then stop!

Step 6:Step 6:The cutter is extended to The cutter is extended to cut off the adhesive papercut off the adhesive paper

Step 7:The Absorber retreats, andreturn to the beginningposition!

Step 8:Step 8:The 4 pneumatics and the The 4 pneumatics and the cutter retreat!cutter retreat!

Step 9:Step 9:The rollers will start movingThe rollers will start movingthe box after a few secondsthe box after a few secondsusing a timer.using a timer.

Step 10:The box is moved to the next stage for frontattachment!and the absorber returnto original position!

Step 11:the Front attachment isthe 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.

The box is

then carried

on for next

process

Advantages

Compacted, everything is done within shorter distance.

It requires smaller area, save space.

Do not require to turn the box by 90 degree.

Disadvantages

Complicated with many mechanisms and parts.

Has to stop for a while, the efficiency will be decreased.

The cost is high.

Adhesive paper design 4

Operation

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.

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

Adhesive machine design 4

By Richard

Operation 1

•First, the box will be picked up by the pump.•Then, the box will be rotated by 90 degrees.

Air pumpConveyor 1

Operation 2

After rotation, the box will be on another conveyor with larger width.

The adhesive paper device will put the paper on the box and smooth the paper.

Cutter

Operation 3

• After the operation, the box will be rotated by 90 degree again.

• Finally, it is putting back to the conveyor for further process.

Advantages

Efficient: Two adhesive papers will be attached and smoothed at the time

Time saving: Time can be saved when two pump is used.

Disadvantages

The structure is complicated.Cost is relatively high.The box have to move and rotate from one

to another place.
