Flexible automated production (HAP) contains technological machines 1, a transport storage system (TNS) 2, having a central storage bin 3, made of sections 4 radially diverging from the bottom of the base 5. On the side surfaces of sections 4 are load-carrying cells 6. Sections 4 are rigidly fixed to the base 5. The base 5 is mounted in bearings 7 mounted on a fixed support and connected to a turn actuator 8 In each section 4 an opening 9 is made according to the largest dimensions of the machines 1 located in the work zone you -THC 2. Near each of the machine 1 mounted manipulator 10. The aperture 9 in each section 4 is L-shaped. Load cells in each section

4, there may be C1 escaping (to have an appropriate shape, a device) for storing the tooling or blanks (parts), or chips. Sections 4 can be made of links 11 pivotally interconnected, having actuators 12, which can be tightly

lindras 13, wherein the working medium can be driven through a distribution system 14 including channels 15 located in the base 5 and connecting power cy-. Lindra 13 through fixed, on the basis of 5 rotation of the coupling 16 and; valve 17, controlled by a command control computer (not shown) and connected to the energy sources of the working fluid.

Section 4 can be equipped with movable, 1st links 18, mounted on guides 19 and having a movement drive g (Figs. 9, 10). In order to rotate and precisely position the storage warehouse 3, sections 4 are mounted on rollers 20 and have locking slots 21 for extension stops 22 installed in the machines 1.

Warehouse 3 may include sections 4 installed in several Rus 23 (including those mounted on the base of the base 5) using ring guides 24 having an individual drive 25 of self-rotation relative to the rack. The power supply to the actuators 25 is carried out by means of the connectors 26 and the channels 27. The self-rotating sections 28 provide for the transfer of products from the start 1 to the machine 1 or from section 4 to section 4.

Warehouse 3 may also include a section-store 29, which is made ring-shaped and has a self-rotation drive 30. On the upper surface of the section 28 are located around the circumference of the cell 6. To interact with this section with other sections 4 or with the manipulators 10, auto operators 31 are installed on the upper sides of section 4, interacting with 3 volumes and with 32 tool magazines made covering radially section 4 in the form of a chain structure.

GAP works as follows.

Manipulators 10 are located between machines 1 (in the initial position) at the same radial distance from the stand as machines 1. When sections A are rotated, manipulators 10 are in the opening zone 9 made in sec-1; and x 4 .

The maintenance of sections A with the manipulator 10 can be organized in two ways.

The first option is the working area of the manipulator 10 is a sector of a cylinder (Fig, 1, 2). In this case, the manipulator 10 serves two machines 1 and two sides of two adjacent sections A, the Machine 1 is serviced by two manipulators 10, the first delivers production objects from cargo trucks, their 6 cells located on one side of section A and returns production objects in them, the second delivers production objects from cells 6 located on the other side of the section and returns production objects to them. The first variant of the maintenance of sections A can provide the transfer of workpieces of tooling from section A of one row of located machine 1 either directly from the machine to another machine or to the section located above it. Rotation of warehouse 3 in the process of such an exchange of production objects is not needed.

In the second embodiment, the manipulator 10 serves one machine and one section completely, both sides (FIG. 3). The scope of the manipulator 10 covers one side of section A, the second side of the section. And it is serviced by the manipulator 10 after section A rotates about the vertical axis 00 on 180 and fixing its position. Fig. 3 shows section A, which is rotatable about the vertical axis 00. The loading and unloading zone for both the first and the second service organization of sections A by the manipulator 10 can be fixed (located in one particular place) and not fixed. If the loading-unloading area is not fixed, then the exchange of production objects with sections A of the HPS 2 is performed simultaneously by any sections A, B of the manipulator function 10, except for loading products from cells 6 of section A to machine 1 and placing them into section A, Includes loading and unloading sections 4, When fixed

The loading-unloading zone of the manipulator mounted in this zone serves the machine 1 and two sides of the adjacent sections A (FIG. 1).

To ensure the acceleration of the transfer of the parts from the storage warehouse 3 to the machines 1 or to the unloading positions of section A, they can have pivot links: 11, hingedly connected to the rest of section A, Servicing the processor 10 cells 6 of section A,. having links 11, is as follows. The external frontal side of link 11 is serviced in its non-deployed position. The cells 6 of the link 11, located on its inner side, as well as the cells of section A, which are closed by it when it is not deployed relative to section A, are serviced by the manipulator 10 after the turn of the specified link 11 relative to section A by 90,

The main purpose of section 28 5 is to provide flexible inter-site communications in the automated area, allowing to process workpieces with any predetermined processing route. In the absence of section 28, a rigid movement path of the blanks in the automated area can be implemented. In this case, the number of machines on which the part will be machined, or the numbers of the first and last machines along the path of the workpieces can be different. In small-scale production, different parts have different technological processing routes and need not necessarily be sequenced on all machines. For example, a part after machining on the first machine should be machined on a third and fifth machine, the rest of the machines should not be involved in the machining of this part. Under these conditions, the operative transfer of the workpiece from the first to the third and from the third to the fifth in accordance with the request by this processing route is carried out by the independently controlled section 28. The preparation after processing on the machine 1 by the manipulator 10 is delivered to section 28, which transports billet (group of blanks) to a given section A of the warehouse 3 in accordance with the technological route of its processing, where the billet was overloaded from section 28 v

Section 4. Freed from Section 28 serves the following remarks. Section 28 also transports the finished parts used by the tool to the unloading area of the TNS 2 and from the loading zone transports the billet in section 4 of various machines 1.

The invention implements three variants of the organization of the instrumental support system using THC 2,

The tooling system according to Fig. 8 consists of a ring-shaped autonomous-rotary section 29, which is the central tool shop, individual tool shops 32, and auto-operators 31. Using the manipulator 10 20, a tool is changed from the control computer using the control computer. spindle machine 1 in accordance with the program of processing parts. In the course of operation, the central shop 29 implements the exchange of tools between the individual shops of 32 tools using the auto-operator 31. Thus, it is possible to exchange tools between the machines in automatic mode from the control computer.

The instrumental support system of the automated section according to the second variant consists of a central tool magazine 29 and individual tool stores for each machine 1 (Fig. 9). Link 18, performing the functions of an individual magazine, has the ability to move along horizontal guides 19. Tools in link 18 can be placed in slots of the moving chain or in slots located along the periphery of the disk, or have a different placement pattern. as close as possible to the working area of the machine being serviced. In this position of the link 18, the tool in the machine spindle is changed by means of the manipulator 10 according to the command of the control computer in accordance with the part program. In the leftmost position of the link 18, tools are exchanged with the central magazine 29. The instrumental support system of the automated section in the third embodiment (FIG. 10) consists of
