Equipment Overview
The equipment is for pushing bread on a conveyor belt sideways to transfer it to a sideways-moving conveyor belt.

There is a stopper in front of the device that pushes the bread sideways, and the stopper opens and closes in a set interval.

Problems with the air cylinder
The speed is unstable with the air cylinder, so when the speed was raised too much, the time it took to push the bread sideways after the stopper opened became too long or too short.

This caused problems like

• The bread being pushed away from the set position
• After pushing, the vertical axis not lifting in time during the return, causing contact with the bread

Such problems caused the bread to get smashed.

CT Effect due to motorization
By motorizing the process, the speed became unified and the movement became accurate. This made high-speed operation possible.

As a result, the cycle time (round-trip movement) reduced from 4.0 seconds to 2.3 seconds. Work time was reduced by 2 hours per day.

Three workers used to be placed on this line to maintain packing machines and restore the product when “Choco Tei” occurred in the process before and after the packing machine. Cost for these labors were reduced.

Process: Marking

Parts are measured and checked by product type using a camera before the marking process.

This data is sent to the XSEL controller using serial communication. The XSEL controller corrects the character size and angle, then moves the pen attached to the Cartesian robot to mark the alphanumeric characters.

This process was previously done by hand, but automating had the following effects.

• The cost of errors that happened when done by hand were eliminated.
• Labor costs were reduced.
• It became possible to fulfill the automation requests by car manufacturers.

Motorizing the removal of defective products made high speed possible and lowered costs.

[Issues Until Now]

• An air cylinder was used for the movement of the plate that removes defective products.
• Adjusting air pressure was difficult, and removal speed was unstable. This caused defective products to get stuck on the entry of the conveyor when the speed became low.
• The speed of the removal conveyor was set slow to ensure the removal of defective products.

[Improvement with Motorization]

• Removal speed was stabilized. This prevented defective items from getting caught at the entrance of the removal conveyor.
• The speed of the removal conveyor was raised.

[Improvement Results]

• Line speed increased by 40%
• Production per day increased from 15,000 units to 21,000 units (1 line)
• Line Stoppage Resolved ・ Labor Cost Reduced
• Annual Labor Cost Reduction Effect of $1,800
