(54) DEVICE FOR REGISTRATION OF THE PERFORMANCE OF A CLOSED CONVEYOR

one

The invention relates to devices for monitoring and recording the operation of machines and is intended to automatically take into account the movement of products when they are repeatedly turned on closed conveyor lines.

A device for counting products that once pass through a conveyor from loading to unloading is known, comprising sensors for moving articles, a pulse distributor, a memory unit, a time delay unit and reversible counters, and inputs of one of. which are connected to the output elements 1.

The known device does not determine the time the product stays on the conveyor during its repeated circulation, which is important if the product is made of a fast-growing material, for example, uncured rubber.

The closest to the proposed technical entity is a device for recording the performance of a closed conveyor, containing the first and second sensors of displaceable products, the output of the last

Reverse meters are used in this device for counting the production, which, first, makes it difficult

The drawing shows a block diagram of the device. The device for registering the performance of a closed conveyor contains the first and second sensors 1 and 2 of moving parts, elements 3 and 4 delays, the first and second elements And 5 and 6, counters 7 to 8, the third and fourth elements And 9 and 10, the block And entering information , the fifth element And 12, the element IL 13, the adder 14, the element 15, the memory block 16, the conveyor movement sensor 17, the pulse distributor 18. The information input unit 11 inputs the value of the work in progress. The device works as follows. The signals from the first and second sensors 1, 2 of moving parts are delayed by delay elements 3 and 4 equal to the distance between the locations of the sensors to move the products. When the signals from sensors I and 2 coincide with the movement of products with the signals at the output of elements 3 and 4, the delays in counters 7 and 8, through the first and second elements, And 5 and 6, are recorded into units, which means respectively hanging on the product conveyor or removing it. The pulse, according to the output of the second sensor 2 for moving parts, is recorded in the cell of the memory block 16, which is selected by the signal with the distributor {8 pulses, received at the corresponding address input of the memory block 16. In the absence of a signal at the output of the second sensor 2, the movement of products, the contents of the cell selected by the distributor 18 pulses through the element 15 are erased. Thus, the number of revolutions made by the product from the moment it is hung on the conveyor to the moment of removal is calculated. At each completion of a complete turnover, the work in progress on the conveyor is calculated. The signals from the distributor 18 pulses reset the adder 14 to the zero state and record, through the fifth element AND 12, the OR element 13, the value of the incomplete at the beginning of the operation period from the information input unit. Other signals from the distributor 18 pulses write to the adder 1-4 through the third and fourth elements AND 9 and 10, the OR element 13 of the compatible counters 7 and 8, respectively. Moreover, the contents of the counters 7 are fed directly, and the counters 8 - in the additional codes. In this device, counters 7 and 8 work only in the summation mode, which facilitates the calculation of the material balance of products on the conveyor in work in progress at the beginning and end of the work and removed from the conveyor. The readings of counters 7 and 8 characterize the total producer, the visibility of the hanging and lifting parts. This mode of operation increases the reliability of the device as a whole. The use of the proposed device allows improving the quality of operational control of sections by reducing losses associated with the uncertainty of functioning of sections operating on a closed conveyor. Reducing the time to receive operational information about the balance of work in progress will ultimately lead to an increase in output and a decrease in simple equipment.
