Description

 The invention relates to the field of general mechanical engineering and can be used in various automatic production lines that require high-speed equipment of variable quantity parts, as well as in ammunition supply mechanisms, for example, for completing modular propelling charges in high-speed self-propelled artillery installations.

 Closest to the claimed method is a known method of assembling parts according to the application of France N 2617145, B 65 G 37/00, 1788, according to which first the parts are placed in a vertically located store in several rows inside the drawers, then for the next technological operation determine the required number of parts and complete a set of them, feeding them from the storage location in the store to the position of completing parts located outside the store and located on the way of supplying parts to the work area, and the supply of parts from each of the first row of the store to the picking position is carried out alternately with the help of two devices for reloading parts. After completing the configuration, the completed set of parts is transferred to the working area.

 This method, although it allows for the acquisition and supply of various parts and the desired working area, however, the use of this method is limited by its relatively low efficiency, due to the large time spent on several sequentially performed auxiliary operations.

 The task to which the invention is directed is to increase the efficiency of the process of assembling parts.

 This problem is solved primarily with the help of the technical result from the use of the claimed invention, which consists in a significant reduction in the time required to complete the entire acquisition cycle and supply parts to the work area.

This result is achieved by the fact that in the known method of assembling parts, according to which the parts are first placed in the store in several rows, then for the next technological operation, the required number of parts is determined and the kit is completed from them, feeding them from the storage location in the store to the position for completing parts, located on the way the parts are fed into the work area,
firstly, the parts inside the store are placed in separate cells and give them to the picking position step by step, moving each part only inside the store,
secondly, the picking of parts selected for the next technological operation from different rows of the store, is carried out among themselves by simultaneously placing them on the picking position, made in the form of a series of elongated in one line directed towards the working area, empty cells of each row of the store, with replacing empty cells in the corresponding row of the store.

 The special initial placement of all components to be completed, as well as the special conditions for completing parts, can reduce the number of required process operations and, accordingly, significantly reduce the time required to complete this work, and, as a result, significantly increase the efficiency of the parts assembly process.

 The possibility of implementing this method is confirmed by the following description of the original design of the installation proposed by the applicant for the assembly of parts.

 The closest in technical essence and the achieved result from its use to the claimed solution is the known design of the installation for assembling parts according to the application of France N 2617145, B 65 G 37/00, 1988. This installation contains a vertically arranged magazine, divided into rows, in each of which are parts, and made in the form of a set of boxes with removable parts, as well as a mechanism for transferring parts to a line directed towards the working area, made in the form of two devices for reloading parts.

 Such an installation, although it allows you to complete and feed into the work area in automatic mode various parts in different combinations, but because of its relatively low productivity, its scope is limited.

 The problem to which the invention is directed, is to increase the efficiency of the process of high-speed configuration and supply of parts.

 This problem is solved primarily with the help of the technical result from the use of the claimed invention, which consists in a significant increase in the productivity of the installation due to a significant reduction in the time required to complete the cycle of picking parts and feeding from the place of their storage to the working area.

 This result is achieved by the fact that in the known installation for assembling parts containing a magazine divided into rows, in each of which parts are placed, and a mechanism for transferring parts to a line directed towards the working area, the magazine is made in the form of a set of parallel independent continuous stepper conveyors with cells for single parts, with one row of cells, one cell for each independent continuous step conveyor, located on the same line inside the store, directed towards p bochey zone composed of empty cells, where all the independent continuous stepper conveyor also perform the function items transmission mechanism on a line directed towards the working area.

The invention is illustrated by drawings, in which
- figure 1 shows the design of the inventive installation for the assembly of parts (front view); parts intended for submission to the work area;
- figure 2 shows a scan of the inventive installation to show the design of continuous step conveyors;
