Referring to FIGS. 13A to 13C , when registering an ERP product when a heat treatment product is received, a barcode-printed process movement table (input sheet) is issued for each container. The process movement table shows the manufacturer, product name, standard, material, required hardness, heat treatment method, container, and weight.

Then, when the work order is given in the order of production management work progress, the work order is set for each unit. When the process movement table is recognized on the barcode reader terminal connected to the computer, the loading amount (KG) for the product, the load shell one input amount, and the sorting device The charging height is automatically set and transmitted to the supply panel (monitor for display of work status).

The supply panel displays the load shell net weight, displays the working time of 1 hour/3,600 seconds, and operates once every 25 seconds of the working time, a total of 144 times per hour.

The pitch progress time is 1~25 seconds, and the amount of work is 1 hour 680kg The processing weight varies depending on the processing setting product.

Residual weight 680kg One-time work load 4.7KG The cumulative total is the total weight made per one time and is subtracted from the remaining amount.

When the feeder frequency (speed) is set to 4.7kg at a time while slowly changing the feeder frequency (speed) to 5Hz when 80% of the product is injected into the loadshell by proceeding with the feeder frequency (speed) 50Hz, the feeder frequency speed stops and operates once every 25 seconds, and operates once every 25 seconds. If the work load exceeds 110% with 4.9kg (count 4.7kg as 100%), when it exceeds 10%, an elapsed sound sounds and the supply device stops. If the weight overloaded on the load shell hopper is removed due to a stop due to excessive loading, it will operate again.

example)

When the barcode is recognized in the process movement table, the alignment device and charging height sensor 1~11 are set, but if you give a command to the 3rd position, it automatically moves after the set time (3rd stage position is set for 5 minutes)

After 5 minutes, the alignment value and the loading amount height sensor automatically move to the 3rd position.

When the heat treatment product touches the loading level sensor, the feeding device automatically stops, and when it is removed, it automatically proceeds again. In other words, if barcode is recognized when inputting a product, the loading amount (kg), one input amount, supply speed, alignment device, loading amount height sensor, etc. are made at once based on the ERP registered product.
