Description

The invention relates to packaging equipment and can be used in the engineering industry and others.

A device for grouping articles is known, comprising a conveyor with sides for products, a lifting and lowering table with limiters for products and a transition mechanism located between THEM and supors 1.

The design of this device allows the transport of groups of products only in the forward direction, but it is not intended to form groups that differ from each other in the shape, number and size of the products.

The purpose of the present invention is to expand the technological capabilities of the device, improving the quality and reliability of grouping, which differ from each other in the shape, quantity and size of products.

To achieve this goal, in a known device for grouping articles by batches, the table’s supporting surface consists of a MOVING and stationary parts, on

the joints between which the teeth are fixed with the possibility of entering one part into another, and the transitional mechanism consists of a fixed and movable comb, installed with the possibility of entering one another, the movable of which is connected to the movable part of the table, while the guides, stops and stops are movably fixed for adjusting the distance between each other. In addition, on the lifting table is fixed cutter for

products.

FIG. 1 shows the proposed device, a general view (T is the lowest position of the lifting table, II is the uppermost position of the lifting table); on

FIG. 2 - section A-A of FIG. one.

A device for grouping products in batches contains a conveyor 1 for supplying products 2, a collecting station equipped with a limit switch 3, made in the form of a moving vertically reciprocating lifting table consisting of moving 4 and non-moving 5, and having the ability to enter to a friend thanks to the serrated grooves 6, 7

Parts 4, b interact with each other with a rack-and-pinion gear 8, with a fused tooth-shaped arm 9 reinforced with a shaft 10, which is located in the body of the fixed part 5, and the slats 8 are connected to the movable part 4. The position of the bottom part 4 is fixed by latches il, which interact with the latter through the slots 12. On the lifting table there is a pair of stops 13, 14, which can fit into each other through grooves 15, 16 and are connected by a guide 17, rigidly connected to the stop 13 and freely - with: limiter I. Limiters 13., 14 sf united through axis 18, rack 19 and housing 20 with j parts 4, 5, led axis 18 can move relative to rack 19, and rack 19 relative to housing 20. The required position of axes 18 and racks 19 is fixed by latch 21.

 On the lifting table, a mechanism is mounted, preventing the supply of other products, made in the form of a trimmer 22, rigidly connected with the movable part 4 of the lifting table.

 Between the conveyor 1 and the lifting table there is a transition mechanism consisting of a basement 23 and a fixed 24 combs, which fit into each other through paragraphs 25, 26. The movable comb 23 of the transitional mechanism interacts with the movable part 4 of the lifting table by means of the holder 27, rigidly fixed on the movable part 4 of the lifting table through the grooves 28 located on the comb 23, the position of the movable comb 23 is fixed by the latches P, which interact with the latter through the slots 29. On the sides of the conveyor 1, and on the comb 23 races olozhena pair of abutments 30 and the guides 3, which can enter into each other due to the slots 32, 33 and .soedineny between a guide 17 rigidly associated with the stop 30 and loosely - with the guide 31.

The stops 30 and guides 3 connect the gots with the frame of the conveyor 1 and the comb 23 through the; axle. , the rack 19 and the housing 20. The required position of the axis 8 and the rack 19 is established by means of the switches 21.

Each of the guided lines, guides, and stops is double-sized, and is flexibly fixed to adjust the distance between them.

A mechanism is provided for withdrawing a group of products in the form of a pusher 34 and conveyor 35, which can be placed both in the direction of transport and in the perpendicular direction.

A device for grouping articles by party works as follows.

The individual products 2 are conveyed by the conveyor 1 so that they fill the entire surface of the conveyor I, bounded by the directions 31, arranged either in parallel rows in the transverse direction or in P1 or so order depending on the shape of the products. As a series of products 2 accumulates on the conveyor, the total friction force between the products 2 and the surface of the moving conveyor 1 overcomes the total friction force between the products 2 and the surface of the lifting table, as well as between the products 2 and the surface of the transition mechanism and the product 2 Next to move to the movable part 4, and then to the fixed part 5 of the lifting table, the surface of which in the direction of motion is limited by the limiters 13, 14. Having collected the required number of rows of products 2, depending on the size of the lifting table in the direction of movement, the front row of items 2 presses the limit switch 3, and the lift table rises to the required height, transporting the group of items made to the plunger 34. In the process of lifting, the slam-shutter 22 rises along with the table, blocking the way for other items which at this time on. are poured on the conveyor 1 in the transition mechanism. The pusher 34 moves the product group to the conveyor 35, the lifting table is lowered to its original position and the cycle is repeated.

The number of products from which a group may be composed depends on the size of the lifting table in the direction of movement, on the distance between the stops 13, 14, the stops 30, the guides 31 and on their height.

The size of the lifting table in the direction of movement can vary within wide limits as follows. By rotating the shaft 10 by means of a rack and pinion gear 8, 9, the movement of part 4 of the lifting table moves along the surface of the body, immobile. part 5, calling in last due to grooves b, 7. Limiters 14, moving together with part 4, slide along guides 17 and entering stop bars 13, thanks to grooves 15, 16. When moving the movable part 4, the holders 27 interact with a movable comb 23 of the transition mechanism through pairs 28 and move the latter to the same distance that part 4 moves, with the comb 23 moving along the body of the stationary comb 24, its exit due to the slots 25, 26. The stops 30 located on the comb 23 move with it, and 17 slides along the guides 31, and the stops 30 exit the guides 3 due to the grooves 32, 33. The required size of the lifting table in the direction of motion is set using clamps 11, which interact with part 4 of the table through the grooves 12, and with the dies 23 - through the slots 29.

The distance between the stops 13, 14 by the stops 30 and the guides 31 (in the cross-section direction of the table) varies by moving the horizontal axis 18 relative to the stand 19. The height of the stops 13, 14, the stops 30 and the guides 31 varies by moving the stand 9 relative to the housing 20. The required distances and heights are set by the clips 21.

The proposed device makes it possible to improve the quality and reliability of the formation of groups of products, and also allows you to make groups of products that differ from each other in shape, quantity, and frame sizes. For example, groups of cigarettes, bottles, cans, bottles, briquettes, various parts of the machine-building industry, etc. can be formed on the proposed device. The expected annual economic effect from the introduction of one machine is 65.6 thousand rubles.
