Description

one

The invention is intended for use in automating the process of sorting sheets on a metal cross cutting machine.

A device for automatic sorting of sheets on cross-cutting units is known, comprising a strip defect tracking unit electrically interconnected, a strip quality quality storage unit, a cutting sensor, a conveyor belt motion sensor and a sheet flow switch 1 control unit. A disadvantage of such a device is unreliability and as a consequence, the need to introduce a special transfer scheme, which significantly complicates this device.

The proposed device for improving reliability in operation is equipped with a switch, the input of which is connected to the output of the cut sensor, a block of sheet memory, the outputs of which are connected to the input of the sheet flow switch control unit, keys of the sheet memory, whose inputs are respectively connected by the output buses of the switch and the output of the memory block of the quality of the strip, and the outputs with the inputs of the blocks of the sheet memory, which are stored with the keys, one of the control inputs of which is connected to the corresponding switch, with its output bus switch And the signal input - a motion sensor of the conveyor belt, as well as counters, the inputs of which are connected to the outputs of the storage key, and outputs - to additional inputs respectively zapominayush their keys and memory blocks sheet heel.

The drawing shows the block diagram of the pre-expanded device.

Block 1 for tracking defects. And the strip with a BMS output is connected to the input of block 2 of the quality memory of the strip, the output of which is connected to the input of all keys 3 of the sheet memory. The cut sensor 4 is connected to the read input of the block of the strip quality parameter strip and the input of the switch 5. The switch outputs are connected to the control inputs of the keys 3. The outputs of these keys are connected to the inputs of blocks 6 of the sheet memory, the outputs of which, in turn, connected to the control unit switch sheet flow 7. The conveyor belt motion sensor 8 is connected to the inputs of the storage keys 9, which are connected to the counters 10 by an input and a switching input to the outputs of the switch. The outputs of the counters are connected by the read inputs of the blocks of the sheet memory and the inclusive inputs of the storage keys.

In the process of cutting the strip, the ia sheets switch 5 receives impulses from the sensor 4

cut. Synchronously with the arrival of AHM pulses, the output signal of the switch moves the enabling signal, which is successively fed to the key pairs 3 and 9. When a pulse is received from the cut sensor on the memory block 2, the information is transferred from this memory block through the currently open key 3 to the block 6. At this time, also opens the key 9 and remembers its state. Through this key, the counter 10 starts, and the pulses from the sensor 8 of the conveyor belt are received. When a counter is formed in a counter equal to the distance from the axis of the scissors to the sheet flow switch, a pulse is emitted from the counter output, meaning that the rear edge of the sheet in question has reached the sheet flow switch. This impulse closes the key 9 and reads from the block 6 the quality information of the next sheet. At this point, a command is issued to set the switch to the position corresponding to the received information.
