DEVICE WITH DIGITAL PROGRAM CONTROL FOR INDUSTRIAL EQUIPMENT

It was filed on August 26, 1960 for L 678167/25 to the Committee on Inventions and Discoveries under the Council of Ministers of the USSR

Published in the Bulletin of Inventions L10, 1962.

Devices are known for automating machine tools based on the use of counting sensors, kinematically associated with an additional organ.

Automation methods are also known that provide quick machine changeover from one part processing to another based on the use of digital software control and computer systems for machine tools.

The proposed device differs from that known by the use of a mechanism for automatically measuring and fixing the dimensions of a moving rolling stock, made in the form of a contact sensor with contacts arranged around the circumference and with a brush moving along them. The brush is connected to a roller reproducing the stanti path. In addition, the device contains a counting mechanism for selecting the optimal cutting program, which provides for minimum waste and a mechanism for adjusting the completeness using a comparison scheme for numbers in order of their order in a row. The comparison circuit consists of individual searchers for each number of a bar line, a common searcher, an individual relay of each bar, and a general purpose relay.

The drawing shows a block diagram of the device.

All pre-calculated parts manufacturing programs constitute the unit / tram storage device. When configuring a device and an aggregate controlled by it for a particular group, program parts that provide for the manufacture of these parts are entered into block 2 of the internal memory of the machine. At the same time, the numerical ratios between the total quantities of parts required by the production task are entered into block 2 of the internal memory.

No. 147431-2. The volume of the internal memory block 2 is determined by the number of combinations of parts.

In addition to programs, the internal memory block contains tuning numbers.

Setup numbers come from block 3 measurements. They are the results of a measurement of a unit of raw or semi-finished product.

For each of the three possible measurement coordinates, measurement unit 3 gives a number. But the tuning part of the internal memory block 2 contains for each program several possible numbers forming a certain numerical zone.

Operations for entering programs, tuning numbers and completeness numbers are performed manually before starting the work; After that, the device goes to automatic operation.

The complete adjustment control unit 4 compares the numbers expressing the relative need for details of each of the dimensions, and determines the type of detail, the need for which is greatest. Details are conventionally distinguished by number.

A feature of the comparison scheme adopted in block 4 is that the numbers are not compared on the basis of magnitude, but on the basis of their location in a decreasing row of numbers. This makes it possible to determine the largest number of rows, not the production of; rhymetrical operations. The number is determined with a part number.

Having determined the number of the part that requires the most, the device sends a signal to adjust the equipment. Signals confirming the manufacture of parts are taken into account by the adjustment unit 4 of completeness. They are subtracted individually from the number expressing the relative need for this part.

During the manufacture of scarce parts, a continuous observation is made of the size of the remaining raw material.

When the predetermined values of the raw material residue have been transferred, the measuring device of unit 3 is turned on and the exact volume of the remaining raw material is measured. The measurement results give tuning numbers, which enter the block of 2-internal memory, and the program is selected.

The data of the selected program is transferred to block 5 of the device’s RAM. The device generates signals for setting up the equipment, corresponding to the manufacture of parts provided by the program.

For best results, programs may contain different part numbers in different quantities.

The counting mechanism of the device associated with the RAM unit 5 takes into account the manufacture of parts according to the number m, compares it with the programmed ones, issues commands “and intermediate changeovers, and, after all program operations have been completed, a signal about its execution. The number of parts manufactured according to the program is taken into account in unit 4 of the regulation of completeness in the form of subtracted from numbers expressing the need for details of different numbers.

After finishing the work on the program, the equipment is again rearranged to produce a deficient part from a new unit of raw material or semi-finished product.

The completeness adjustment unit 4 and the operative memory unit 5 are connected with the sorting storage unit 6. If the unit 7, controlled by the device, has a part sorting unit according to numbers, the sorting is automatically controlled.

The block 6 of the memory device stores the number of the part made by the units. This number is the same address as the part.

The sorting counting device takes into account the path traveled by the part along the sorting path and compares the actual address of the part with the address specified in block 6 of the memory. If the addresses match, a reset occurs flying into the .bunker.

The proposed device is practically applied to control an assembly that opens long products.

The initial parts of the rolled steel are disclosed to the details of the deficit number, and the end parts (within 4-5 g) according to the programs.

The device is made on the relay-contact elements. The volume of the internal memory block 2 is chosen to be forty programs. Each cutting program contains information on the number and numbers of the parts included in it, and the tuning numbers. Programs are recorded on punched tapes and entered into block 2 of internal memory, made in the form of a plug-in switch.

Measurement unit 3 is made in the form of a contact sensor. The contacts are located around the circumference and the brush moving along the rollers reproducing the path of the moving rental bar moves along it.

The completeness adjustment unit 4 is made on, relays and step finders.

The memory block 5 and the computer program of the programs are made on the relay. The block 6 of the memory and the block 7 of the counting sorting device are made on the relay and schagovyh searchers.

The 8 digitally controlled cutting unit is designed for harvesting shops of agricultural machinery plants, materials handling equipment and other factories that use high-quality rolled products in large quantities.

The Research Institute of Agricultural and Tractor Mechanical Engineering manufactured a prototype of the proposed device complete with a nesting unit.

The prototype passed technological tests and is intended for implementation at the Rostselmash plant.
