The disadvantages of the known device are the following: the presence of a central source of programs necessary to store information about the processing of a part, limiting the range of parts to the capacity of its memory, increasing the number of communications to the machines, the need to stop the entire production in case of malfunctions in the central source of programs; the availability of a central tool for controlling the location of the instrument and controlling the traffic flow, leading also to a significant increase in communications

and causing a halt in production; the connection of all machines with a central source of programs, which, in the case of processing parts of one batch on all machines of the same type at the same time or with a small time difference, forces to have devices for reproduction and displacement of parts processing programs.

Thus, the main drawback of the device is the complexity of its construction. .

The purpose of the invention is to simplify the device.

The goal is achieved by the fact that the device contains a mobile block of parameters for a part, the inputs of which are connected to the output of the storage unit from the first to fifth, with the third output of the machine control unit, with the second output of the control unit, with the first and second inputs devices, from the first to the eighth outputs of the mobile block of parameters memory, parts are connected respectively to the second input of the decryption block of commands, with the fourth input of the storage unit of the warehouse parts, with the fourth input of the unit pack machine, with the fourth input of the tool search unit, with the second input of the control unit and with the first, second outputs of the device, the third input of which is connected to the fifth input of the storage unit of the storage parts and the third input of the control unit, the fourth input and the third output of which are connected respectively with the fourth input and the third output of the device.

The device contains (Fig. 1): block 1 display and setting modes, block 2 memory production state, block 3 Coptrol, block 4 memory warehouse parts, block 5 command decryption, block 6 addressing, block 7 control the machine, block 8 tool search, moving block 9 of part parameter memory. In addition, the positions 10 and I denote the mobile memory blocks of the part parameters of two adjacent production sites.

An embodiment of the device may contain (FIG. 2): satellite 12, transport 13, robot manipulator 14, personal store 15, reloading position 16, addressing means 17, storage of workpieces 18, accumulator 19, machine 20, supply branch 21 of transport, place 22, robot loader 23, chuck 24, central tool store 25, transferor 26, satellite 27, cell 28 of the warehouse of blanks.

The notation in FIG. 3 are similar to those in FIG. 2

The device for production control works as follows.

Procurement on satellite 12 with information in block 10 of the previous production site containing the address of the initial data of the part processing and robot control data on transport 13 of the previous production site goes to its reload position. From the reloading position, the robot manipulator 14, depending on the program read, transfers the workpiece, if necessary, to its edge, to the satellite 27 (Fig. 3) of this section, which is currently at the reloading position 16, or to the free cell 28 of the warehouse 18 workpieces while simultaneously transmitting information by reading and writing either to block 9 of satellite 27 or to block 4 to us of warehouse parts 18. At the same time, information on the presence and type of workpiece is transmitted to block 2, which is reflected on block 1 upon request. The production is planned in advance and transferred to unit 1.

Releasing accumulator 19 of any machine 20 calls the workpiece from warehouse 18. If any workpiece can be processed on any machine (impersonal mode of operation), the robot arm 14 installs the next workpiece on the rim 27, remove it from the cell 28 of warehouse 18. When addressing mode operation of the reader when moving the cells 28 of the warehouse 18 is carried out by detecting a certain workpiece, followed by installing the overload position 16 on the free satellite 27. In both cases, the information is transmitted to the satellite block 9, which is e clamp parts is moved via a feed branch 21 of transport. In the case of the address mode, the addressing information of this satellite is read at the isolation locations 22, and the satellite is sent, depending on the address, to the drive 19 that caused it. If any workpiece can be processed on any machine, the latter will unbind the calling device stops the first satellite 27 that arrives at the supply branch 21 of the transnort and sends it to the indicated accumulator, simultaneously calling a new stock from warehouse 18 to replenish the accumulator that caused previous workpiece. Taking into account that the time of transportation of the workpiece from the warehouse to any of the drives 19 is less than the minimum processing time, the machine is always provided with blanks in the drive.

According to the program of the machine, at the end of the machining of the part, the twin-spindle headstock is rotated by 180 °, the workpiece pre-installed by the robot 23 in the cartridge 24 and the part removed from the machining zone with the simultaneous call of the robot loader 23 are entered into machining. and the range of time to remove a part and load a new one is equal to the time it takes to process a part, and simple machine tools are excluded due to the expectation of a robot. Machine maintenance robot loader 23 performs in order of priority. Simultaneously with loading the workpiece into the machine spindle, information is transmitted by reading and writing to block 7 via the machine, as well as transferring information to the tool search in the central tool store 25 with the tool search block 8 and unloading it by the non-depositor 26 into the individual store 15. For processing the subsequent part, only the tool that is missing in the individual store 15 is selected. After processing the details of the tool, the tool that is not used for the subsequent part is returned aets in neutral store 25. Thus, while the machine handles the details of one party, Saanen tool in the individual store 15 is made only to the extent of its deterioration, but nomenclature of the tool remains constant. When returning the instrument to the central store 25 in block 2, data about the number of a specific instrument in it is received. BECAUSE the machine 20 has in the control unit 7 of the machine control the DEVICE of monitoring the condition of the tool, there is no need to take into account the total velt of his work and his replacement is carried out by the command of the control device with simultaneous transmission of this command through the control unit 7 of the machine 20 to the block 1.

The robot loader 23 installs the machined part on the same SATELLITE 27, WHICH he takes to prepare it on the machine with simultaneous transmission and formatting of the actual condition of the part received from the mounted part program of the specified part from the control unit 7. Block 9 of the southeast 27. Then the SATELLITE 27 with the part and information about it is sent according to the further technological process either to the semi-finished goods warehouse or to the finished parts warehouse, which is done by address means nn 17, at the places where the freight traffic is unfolded, we should read the address information and the corresponding direction of the satellite 27.

SATELLITE 27 stops at the corresponding overload position 16. Calls the robot-matipulor 14. Which reads information from the second 9 of the satellite 27 and, in case of the necessary part, loads the order into one of the warehouses, or overloads to the transshipment position of the transport of the subsequent production site. In this case, information about the actual state of the warehouses is sent to block 2, which, if necessary, is reflected in block 1.

The operation of the equipment from the warehouse of semi-finished products is similar to the work from the warehouse of blanks. The part from the finished parts warehouse by the robotic manipulator 14, if necessary, is turned over and unresponsive to the transport of the subsequent production site and installed on the satellite with simultaneous transmission of information on the actual condition of the part by reading and writing in block 11, and then the smudge is sent to the next production system.
