Description

The invention relates to the automation of technological processes in mechanical engineering, mainly for flexible automated assembly production.

The aim of the invention is the expansion of technological capabilities due to the simultaneous assembly of products of different nomenclature.

The drawing shows an assembly line that implements the proposed method.

An automated assembly line contains a working 1, distribution 2, return 3 and auxiliary 4 conveyors, transverse conveyors 5-14 for connecting conveyors 1-4, satellites of the first type 15 -19 for assembling the base unit and mounting attachable nodes at the base unit, satellites of the second type 20 - 23 for assembling the connected nodes, the device 24 - 27, 28 for reading the satellite code, the device 29, production assemblies. The essence of the invention: products are collected on satellites and transported on encoded satellites separately with base and attached nodes to the assembly modules. Then, selective supply of satellites with attachable nodes to the assembly module is performed in the quantity and design corresponding to the design of the base unit served in the satellite before receiving the satellites with the attachable nodes. This ensures the launch of automated lines for the assembly of the next product execution while completing the assembly of products of previous designs. 1 ill.

Satellites are equipped with a carrier code for the execution of nodes. The satellites of the first type have conditional codes: satellites without a base node 15 — AO code; satellites with a base node of the first execution 16, the second execution 17, the third execution 18 - codes A1, A2, respectively. AZ: satellites with assembled product 19 - code C1. The satellites of the second type have conditional codes: satellites without an attachable node 20 — VO code;

Worker 1 and distribution 2 conveyors are connected by transverse conveyors

5. 7, 9 with the possibility of supplying satellites to the assembly modules and transverse conveyors 6, 8, 12 with the possibility of returning the satellites to the distribution conveyor. Distribution 2 and return 3 conveyors are connected by transverse conveyors 13, 14 with the possibility of organizing a buffer storage of satellites. Auxiliary conveyor 4 is located in the module area parallel to the working conveyor 1 and is connected to the distribution conveyor 2 using a transverse conveyor 10, which provides satellites 21, 22, 23 with attached nodes to the module 35 and a transverse conveyor 11, which returns satellites 20 without an attached 'node to the distribution conveyor. Devices 24 - 27 of reading the satellite code are located on the distribution conveyor 2 in the zone of supply of satellites to the assembly modules. The satellite code reader 28 is optional and located on the working conveyor 1 in the satellite feed zone with the base unit to the assembly module 35. The satellite encoding devices 29.30 are located on the working conveyor 1 in the satellite transmission zone to the distribution conveyor 2. Reset devices 31.32 the satellite codes are located on the working 1 and auxiliary 4 conveyors in the satellite issuing zone, from the assembly module 35. A commercially available programmable controller can be used as a command generation unit, e.g. KPM-30-01 IGFR.468361.002 TU. Block 36 with the help of mathematical software has the ability to process information received from the code reader 27 located in the aeon of supply of satellites 21, 22, 23 to the assembly module 35, and the additional code reader 28, and then issue commands to the mechanisms providing supply of satellites 21, 22, 23 according to the code (execution of the connected node) and in the quantity corresponding to the code (execution of the base node) of satellites 16, 17, 18, submitted to the assembly module 35 before receiving satellites 21,22, 23. As a system 37 aut automatic addressing of satellites, a complex of technical means can be used on the basis of serial programmable controllers, or microcomputers,

The structural diagram of an automated assembly line shows an example of a specific implementation of the method for assembling products of three versions (the number of versions of products simultaneously assembled on the line can be increased in accordance with the capacity of the satellite code carrier).

Satellites of the first type of base unit 15 (conditional code-AO), according to the code received from the reader 25, are sent by the control system 37 and conveyors 2, 7 to the assembly module 33. After assembly, the satellites are transcoded by the device 30 in accordance with the execution of the base unit (conditional the codes are A1, A2, AZ) defined by the control system 37, and they are sent by conveyors 1,8, 2, 9 to the assembly module 35. Satellites of the second type without base unit 20 (conditional code - BO) are also supplied by conveyors 2, according to the code, 5 to the assembly module 34. Collect at the joining node and recode the satellites in accordance with-its execution (conditional codes - B1, B2, EOI) given by the control system 37. The coded satellite nodes with attachable directed conveyors 6, 2 to the assembler module 35.

Satellites of the first type with a base node of versions A1, A2, and AZ, upon arrival, piece by piece conveyor 1 passes to the assembly module 35. At the same time, the code is read by the device 28 and information is transmitted to the processing unit 36. From satellites of the second type with a connected 'node of versions B1, B2, OTs, upon receipt, also read the code by the device 27, and the code information is transmitted to the processing unit 36. When the satellite code with the attached node matches the satellite code with the base node, the block 36 issues commands to the conveyor mechanisms 10.4, which the satellites provide with the attached node in a given quantity to the assembly module 35. If the satellite codes do not match, the satellites with the attached node are sent to. buffer storage organized by conveyors 2, 13, 3, 14.

On the assembly module 35, the attachable nodes are removed from the second type satellites and the product is assembled on the first type satellite. The codes from the satellites are reset by devices 31.32 (transcoding into conditional codes AX (AO), (BO). The second type of satellites without nodes (conditional code BO) are sent to the assembly module 34 by conveyors 4, 11,2, 13, 3, 14 , 2. Satellites of the first type with the product (conditional code-C1) are transported by conveyor 1 to the next assembly module for subsequent operations, or to remove the product 5 from the satellite, after which satellites without nodes are sent by conveyors 1, 12, 2, 13, 3, 14. 2 to the assembly module 33.

By supplying satellites to the assembly module 35 with satellites 21, 22, 23, according to the code and in the quantity corresponding to the satellites with the base node 16, 17, 18, filed individually before receiving satellites 21, 22, 23. it is possible to simultaneously assemble complex products of different nomenclature, it is not necessary to stop the automated line when the assembly of the current product is completed and to restart the line when switching to the assembly of the next product, which reduces the time for reconfiguration of the automated line and expands its technological some opportunities.
