Further, a scrap collecting box 90 is provided at a position directly opposite to the rejecting device 80, and the food cans 100 rejected by the rejecting device 80 can be collected in the scrap collecting box 90.

The embodiment of the utility model provides an automatic sign indicating number equipment of beating of this food jar need not shut down the operation, to food jar 100 impel, beat the sign indicating number, detect, the defective work rejects each other and does not influence, degree of automation is high, has improved the efficiency of beating sign indicating number work widely, has reduced operator's intensity of labour.

It should be noted that the embodiment of the present invention provides an automatic coding device for food cans, which performs unified coordination control on each electric component through a control device (not shown) during operation, so as to ensure coordination of each device or mechanism, thereby achieving automation. The control device can adopt a PLC (programmable logic controller) or a computer which is formed by the prior art and has mature technology, and programs are set according to the time requirements so as to control the coordination work of each device or mechanism.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
