Description

The utility model relates to industrial transport, in particular to devices for piecewise transverse movement of long products and can be used in the machine-building industry related to the processing of long length material, for example, in metallurgy, forging and stamping, etc., as well as in the construction industry .

From the patent of the Russian Federation 2043286 (publ. 09/10/1995) a device for disassembling packages of long products is known. The device comprises a unit for the delivery of blanks from a package and a tilter. The unit for dispensing workpieces includes a swinging grate, curved movable beams with the possibility of rotation on the axis, a fixed beam and at least two trolleys on a chain drive that can be moved along the fixed beam. The carts are equipped with hydraulically shaped figured forks, which can be rotated on the pinion shaft, which is meshed with the rack. Figured forks are made with teeth of different lengths, and the teeth are equipped with hooks.

The package is placed on a swinging grate, the movable beams are tilted using an eccentric mechanism, and part of the workpieces falls on the fixed beams. Dismantling the package from the fixed beams and moving the workpieces along the specified beams is carried out by manipulating trolleys and figured forks. To do this, the hooks of the figured forks are brought to the package from below and the carts are horizontally moved, removing the lower workpieces from under the upper hooks. The upper workpieces are pushed using a hook on an elongated tooth.

Then the workpieces are shifted by the tilter using slotted cutouts on the figured forks. Scanned blanks are pushed with an elongated tooth onto the roller table.

The disadvantages of the device are its complex design, low reliability of piece-wise separation of blanks from the package and low reliability of transferring blanks with a tilter.

For the closest analogue, a piece-by-piece device for moving long products according to the patent of the Russian Federation 485584, published on 09/25/1975, was selected. The device comprises a conveyor, three groups of fixed and movable beams with a toothed working surface mounted parallel to the length of the workpiece. Each group includes two movable beams and one fixed beam. The movable beams are driven in reciprocal motion in antiphase using eccentrics. The first group of beams is mounted obliquely and equipped with a pivoting tilt lever located behind it. In the second and third groups, the movable and fixed beams are equipped with an inclined flat front section and are made with the arrangement of their serrated profiles on the curved sections of the beams.

The movable beams of the first group capture the ends of the products from the conveyor with their teeth and move them along the teeth of the stationary beam of the first group at a speed exceeding the speed of the feed conveyor. As a result, the front end of the product is removed from the bag. The beams of the second and third groups by the front sections of their movable beams, playing the role of a vibrating table, split the package and separate from it the product captured by the beams of the first group. Further, the beams of the second and third groups capture the product along the length of the teeth of its movable and fixed beams. The ends of the products that have reached the upper part of the beams of the first group are transported further by the rotary lever-tilter, and the products roll down the rear inclined planes of the first group of beams.

The disadvantages of the closest analogue:

- The tooth profiles, the shape of the beams and the orientation in the space of the first group of beams are different from the profiles of the teeth, the shape of the beams and the orientation in the space of the second and third groups of beams, which complicates the manufacture and installation of equipment. In addition, the teeth of the second and third groups of beams have a different shape due to their implementation on the curved sections of the beams, which requires great precision manufacturing.

- A small range of regulation of the working stroke of the beams, limited by the magnitude of the eccentricity of their mechanism.

- It is not excluded that the products may overlap when moving, because separated from the bundle and move the product at their ends, i.e. the movement of products is not parallel.

- The beams of the first group are installed obliquely with the movement of the products up, which does not exclude the fall of products under the action of gravity.

- The tilter is installed only on the extreme group of beams, which is associated with the risk of overlapping products with each other during transportation.

- The tilter can only push the product from one end, without grabbing the product, which is unreliable.

- No drive, i.e. there is no stacking of products in a row in front of the tilter, as a result, the tilter can idle, which leads to irregular work and malfunctions in the process.

Thus, this device of piece moving long products is unreliable in operation and has a complex structure.

The technical problem, which is aimed at solving the utility model, is to ensure reliable operation of the unit piece moving long products, while simplicity of its design.

The proposed utility model allows to obtain the following technical result:

- guaranteed piece selection of products from the pack;

- the exclusion of overlapping products during the analysis of the pack, moving along the beams and in the process of shifting to the issuing conveyor;

- ensuring non-stop operation of the tilter and subsequent equipment;

The technical problem is solved in that the device for piecewise movement of long products, like the closest analogue, contains a group of fixed and movable beams with a toothed working surface and a rotating tilter placed behind them. Unlike the closest analogue, the beams are made with the identical tooth profile, the movable beams have the possibility of synchronous vertical lifting-lowering, the movable and fixed beams in each group are installed with offset tooth profiles, the fixed beams are equipped with inclined rear sections, and the tilter contains at least two a disk with cutouts for capturing and dispensing products.

In this case, the displacement of the tooth profiles of the movable and fixed beams is made for guaranteed piece selection of products from the pack.

In addition, each of the tilter disks can be made with at least one notch.

In addition, each cut-out is asymmetric for single-piece capture of the product by one side of the cut-out and delivery of the product from the other side of the cut-out.

In addition, each group of beams may contain an additional fixed beam made with a smooth horizontal section and an inclined rear section.

In this case, the fixed, movable and additional fixed beams are mounted mirror symmetrically, and further from the axis of symmetry are additional fixed beams.

In addition, bumpers are installed at the lower ends of the inclined rear sections of the fixed beams.

In this case, each chipper can be made in the form of an elastic element or a rigid stop.

In FIG. 1 shows a device for piece moving long products; in FIG. 2 - a device in the form AA of FIG. 1. In FIG. 3a, 3b, 3c, 3d schematically shows a group of beams, respectively, in the initial position, when lifting the movable beam to the middle position, in the upper position of the movable beam and the lower position of the movable beam.

The device of FIG. 1 contains groups 1 of beams, each of which includes a fixed beam 2 and a movable beam 3. The movable and fixed beams 3 and 2 are located mirror symmetrically. The movable and fixed beams 3 and 2 are installed in parallel and are made with an identical serrated profile in their horizontal sections (Fig. 2). The movable beams 3 have the possibility of synchronous lifting and lowering by means of electrically controlled mechanisms 4. The fixed beams 2 are equipped with smooth inclined rear sections 5. At the lower end of each inclined rear section 5 there is a chipper 6 which can be made in the form of an elastic element, for example, a cantilever fixed spring , or hard stop. Next, a tilter 7 is installed (Fig. 2), which is at least two disks 8, rigidly mounted on a rotating shaft 10, on a support structure that is integral with the beams. Each disk 8 is made with one or more cutouts 9. In FIG. 2 shows an example of a tilter 7 with two diametrically opposite cutouts 9. The output conveyor 11 can be made of a roller type. Each group 1 of beams can be equipped with an additional fixed beam 15 located further from the axis of symmetry compared to beams 3 and 2.

Consider the operation of the unit device for moving long items.

A pack of long products 14, for example, a cylindrical profile, in particular rods or pipes, is placed on a fixed beam 2 (Fig. 2). In the initial position (Fig. 3a), the movable beam 3 is in its lower position. The electrically controlled mechanism 4 of the movable beams 3 is turned on. When lifting the movable beams 3 (Fig. 3b), the tops of their teeth split the pack of products 14 due to the fact that the movable and fixed beams 3 and 2 are installed with a displacement of the tooth profiles by a distance of L (see Fig. 3a) guarantees piece selection of products from the pack. In the upper position of the movable beam, the articles 14 separated from the stack are rolled towards the next cavity between the teeth of the fixed beam 2 (Fig. 3c). Then the movable beam 3 is lowered to the lower position, and the products 14 separated from the bundle slide into the cavity between the next teeth of the fixed beam 2 (Fig. 3d). When this product 14, captured by groups of beams 1 from both ends, move in parallel. Subsequent cycles of raising and lowering the movable beams 1 lead to a piecewise separation from the stack of the following products 14 and a stepwise parallel movement of the separated products 14, which eliminates the overlap of the products during movement, even in the case of curved products.

For processing products of increased length are additional fixed beams 15 having a horizontal supporting 16 and an inclined rear surface 17 (Fig. 1).

Further, the products 14 roll along the inclined rear sections 5 and 17 and accumulate on them, and the extreme product 14, when it rests on the chippers 6, is located in the area of the cutouts 9 of the tilter disks (Fig. 2). The length of the inclined rear sections 5 and 17 (storage capacity) provides non-stop operation of the subsequent equipment, the chipper 6 softens the impacts of the products 14 and dampens the vibrations of the structure.

When the shaft 10 of the tilter is rotated, the end product 14 is captured by cutouts 9 of a trough-like shape (FIG. 2), and the depth of cutouts 9 prevents the product 14 from falling out during transport by the tilter 7. The asymmetric shape of the cutout 9 facilitates piece-wise capture of the product 14 by one side of the cutout 9 (FIG. 2), and the issue of the product after transportation on the other side of the cutout 9. Due to the fact that two disks 8 of the tilter are installed at both ends of the product, overlapping of the products during transfer to the delivery conveyor 11 is excluded.

Thus, a reliable and rhythmic operation of the device for piece-wise movement of long products, from disassembling the bundle to entering the delivery conveyor, with the exception of overlapping of the products, is ensured.

In addition, the implementation of the movable and fixed beams 3 and 2 with the same toothed profile in their horizontal sections, as well as with the teeth of the same shape, easy to manufacture, significantly simplifies and unifies the design of the device.
