SU971736A1 - Stepping accumulating conveyer - Google Patents

Description

The invention relates to mechanical engineering, in particular to conveyor devices of automated lines, and can be used for transportation by receiving, storing and entering products.

A known chain conveyor drive contains parallel endless traction chains interconnected by axes on which freely rotating supporting rollers are mounted, with rollers mounted in guides located at the ends of the axle, an additional supporting guide is installed at the loading point of the conveyor having a stop placed in months. Those unloading conveyors, while at the end of each carrier roller an additional roller is cantilevered, the diameter of which is less than the radius of the carrier roller, and the additional roller interacts with the additional anchor rail made in the form of a movable one from water in the vertical plane of the wedge 11.

The disadvantage of this chain conveyor drive is that it provides only a small amount of

accumulated products, due to the length of the conveyor. As a result of the lack of a reception and delivery mechanism, the loading and unloading of the transported products is carried out individually, which reduces the productivity of the conveyor. The use of loading products on this conveyor in several rows simultaneously drastically reduces

10 the reliability of his work.

The closest technical solution to the invention is a stepping conveyor drive comprising a frame with closed chains mounted on it, connected pargill-type slats, a conveyor belt and a supporting element 2.

The disadvantage of this stepping conveyor is its relatively low productivity due to the formation of unloaded discharge sections when the supply of parts from the supply conveyor is stopped.

The purpose of the invention is to increase the capacity of the storage conveyor.

This goal is achieved by the fact that a stepping conveyor drive containing a frame with mounted on

Claims (2)

30 closed chains, connected by parallel strips, the conveyor and the supports of the Hbtfi element are provided with brackets attached to the chains, on which the strips are fastened, the conveyor is made of three sections with gaps between them, the slats are located above the conveyor, and the supporting element made in the form of a plate placed under the slats at the level of the conveyor. 1 depicts a stepping conveyor drive; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 1. The stepping conveyor drive has parallel-arranged closed traction chains 1 moved by drive sprockets 2 placed on shafts 3. Shafts 3 are mounted in brackets 4 fixed to the frame. At the end of each shaft 3 there is a ratchet mechanism for providing stepping feed chains 1, including a ratchet wheel b, pawl 7 and stop 8. To drive chains 1, there are hydraulic cylinders 9 and 10, placed on frame 5 and working one for loading products into the drive and the other for unloading them. Perpendicular to the chain and above them there is a mechanism for receiving and dispensing products with tray 11. The bottom of tray 11 is made in the form of a middle section of a tratier 12, for example, roller, plate or tape type. The conveyor 12 is equipped with a movable shut-off device 13. For the drive of the conveyor 12 there is an electric motor; body 14. Traction chains 1 are connected to each other by parallel bars 15 fixed above support element 16 on brackets 17. For free movement of transported products from the reception and delivery mechanism to the hopper and back, the plate supporting element is installed at the same level with the conveyor plane 12, on which the products are located. The slats 15 are placed parallel to the axis of the tray 11 at a distance equal to the width of the middle section of the conveyor, forming the walls of the tray 11 for guiding the products coming from the feed section 18 t of the conveyor belt. The middle section of the transponder 1 is installed between the inlet section 18 and the outlet section 19. With the possibility of passing between them in the gaps 20 and 21 of the brackets 17. The storage conveyor can operate in two modes: in the receive and accumulate mode and in the release mode. The conveyor operates in accumulation mode as follows. Products are delivered to the bottom of the tray 11 of the mechanism for receiving and issuing products at the intake section of a traporter. The middle section of the conveyor 12, which is driven from the electric motor 14, of the product, slips from the rest of the way into the cutter 13, which is closed when the conveyor is in accumulation mode. The walls for the products moving on the conveyor 12 are served by the walls of the tray 11 formed by parallel strips 15 connecting the pulling chains 1. After the receiving and dispensing mechanism conveyor section 12 is completely filled, the hydraulic cylinder 9 is commanded to load. Cylinder E drives the ratchet pawl 7. The dog departs from the stop 8 and, approaching the protrusion of the ratchet wheel b, turns it, and with it the shaft 3 with driving sprockets 2 chains 1 on it. The traction chains 1 are set in motion. At the same time, the parallel strips 15 move over the conveyor section 12 and move the products — the storage support element 16 by one row. At this time, the subsequent strips 15 are installed above the conveyor section 12, forming the guiding walls of the tray 11 for the next row of incoming products. Further, the operation cycle of the conveyor belt is repeated. . The conveyor operates in unloading mode in reverse order. When unloading, the command is given to the hydraulic cylinder 10 and the product is moved. The strips 15 from the support element 16 are transported to the conveyor section 12. In this case, the cutter 13 is opened and the products are conveyed to the discharge section 19 along the conveyor sections. Then, the cycle of operation in unloading mode is repeated. This invention provides batch loading and unloading of products, which leads to an increase in productivity of the stepper conveyor. Invention A stepping conveyor drive comprising a frame with closed chains mounted on it, connected by parallel strips, a conveyor belt and a supporting element, characterized in that, in order to increase productivity, it is provided with chain-attached brackets on which the slats are fixed, the conveyor is made of three sections with gaps between them, the slats are located above the conveyor, and the supporting element is designed as a plate placed under the slats at the level of the conveyor.
