For the processing of large cabinet clamps, single-position speakers connected to a conveyor are most often used. For smaller zags, ALs consisting of multi-position AS are appropriate. AL is a system of automatic machines located along the TP, which are united by transport devices and general control systems. The disadvantage is one-subject.

Advantages:

Possibility of implementing optimal TP; - the reliability of agricultural nodes increases, because there is repeated use;

Increase your production; - repeated use of elements of agricultural units; - simple solution to transport issues; - short terms of commissioning into production; - increased economic efficiency.

Main components: ag-e power heads. Other components: rotary power tables, beds.

AL layouts:

b) single-threaded //-th action(Fig. 5.4.2) is used to perform one operation when continuing it means. exceeds the required rate of release.

c) multi-threaded(Figure 5.4.3): designed for performing several operations, each of which is longer than the specified production rate.

d) mixed(with branching flow) (Figure 5.4.4): 1-working units, 2-distribution devices.

Typical layouts of automaticlines from aggregate machines and areas of their application.

Automatic lines in their simplest form are assembled on the basis of modular machines connected by a transport system. Automatic lines from modular machines can be divided into two main groups: lines with direct movement of workpieces from machine to machine (Group I) and lines with movement of workpieces in satellite devices ( II group).

Group I lines, depending on the method of moving parts between machines, can be divided into lines with through or direct-flow transport and with remote transport. In the first case, the parts conveyor passes directly through the working positions and the parts move in the same direction. In the second case, the parts conveyor is located behind the machines and the parts, in addition to moving from one position to another, additionally move perpendicular to the main conveyor, which is necessary for feeding them into the machine tools.

Processing schemes for automaticlines from aggregate machines.

1 Diagram of an automatic line of four machines with the same position of the part on the machines; processing is possible only on both sides; 1 loading of parts; 2, 4, 6 and 8 - working positions; 3.5 l 7 - intermediate positions; 9 - unloading parts

automatic line with intermediate rotation by 90°, processing of parts is possible on four sides

Lines of aggregate machines are lines with a rigid connection, and the downtime of any machine causes downtime of all machines in the line, which significantly reduces the technical utilization rate of the line, i.e. its actual productivity. To increase the utilization rate of lines consisting of a large number of machines, they strive to divide the lines into sections and introduce parts storage between the sections, i.e., create automatic line systems. 3 Diagram of a two-section systemautomatic lines: /-loading parts; 2 - 4, 6-3, 12 -16 working positions; 5 - rotary table; 9 - intersectional conveyor; 10 - intermediate storage; // - rotary drum; 17 - unloading parts 3rd section II section
