Description

one

This invention relates to devices for receiving raw, freshly molded articles, such as bricks, from a press for semi-dry pressing silicate, ceramic and other stones or blocks, and transferring the blanks to reloading devices for further transfer to parquet platforms.

A device is known for receiving freshly molded articles from the press, for example silicate -KHpinnMa, which contains a frame, a vertically closed conveyor with an actuator, load-carrying elements and a mechanism for expanding the load-carrying elements.

However, in a known device, when forming a series of articles, the product slides over the surface, which degrades the quality of the surface of the products.

The purpose of the invention is to improve the quality of products during the formation of rows.

This is achieved by the fact that under the upper branch of a vertically closed conveyor the upper and lower directions are mounted, the rails on which the rollers of the sliding cargo carriers rest, their elements made in the form of hinged diavans with support plates, headers, and in the upper direction the rail is The curvilinear is located in the horizontal plane: a groove, and the lower direction is Yush, and the rail consists of articulated links, “the outer ones of which are located in the horizontal plane, and the middle one is inclined.

In addition, the support platform is made in the form of a jumper, in the middle part of which a plate, lined with an elastic coating, such as rubber, is rigidly mounted, and plastinas equipped with pins that enter the curved groove of the upper guide rail are freely installed at the ends. .

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same plan; in fig. 3 - the same, side view; in fig. 4 is a section through A to A of FIG. one; in fig. 5 - a section on BB on fpg. one; in fig. 6 is a section along BB in FIG. one; in fig. 7 - node I on

fng four.

The device contains a 1T drive shaft 1 connected to a periodic rotation drive and a driven shaft 2 mounted remotely from the first one and parallel to it.

The housings of the shaft 3 sub-branches of the drive shaft are fixed, while the housings of the bearings of the 4-shaft are fixed with the possibility of movement. by means of screws 5 in the horizontal direction from the middle position.

Two identical vertical gear disks 6 are mounted on the shafts. Every two opposite disks mounted on different shafts are wrapped around endless load-carrying bodies 7 (platforms). Each body carrying the body consists of an even number of pairs of double articulated discrete elements 8, equipped with rollers 9 placed between the elements on their hinges.

The load-carrying organs are mounted in such a way that their lower branches sag freely, and the upper ones are mounted with limited mobility in a vertical plane by a system of rails consisting of upper janer rails 10, horizontal lower inlet rails 11, horizontal lower output rails 12 and lower intermediate inclined rails 13 , with the latter pivotally connected to the inner ends of the input and output rails. The upper and lower input and output rails have brackets 14 for attachment to the frame (not shown in the drawings) with the possibility of adjustment. Along the entire length of its lower surface, the upper rail has a rectangular plane in contact with the rollers, the width of said plane being equal to the length of the rollers. The same width of the prince of the lower rails that are in contact with the rollers of the upper planes ensures reliable direction of the load-carrying organs.

The discrete elements of the upper branches of the load-carrying organs at the site of receiving blanks are located in one line straight-line, and at the areas of shifting and forming the layer of blanks zigzag. In the latter case, the contacting of the rollers alternates between the lower plane of the upper copying rails and the upper plane of the lower output and intermediate rails. At the same time, the horizontal pitch between the alternating rollers gradually decreases in the shearing area and reaches a minimum at the forming section, which is equal to the pitch between the rows of blanks after they are displaced. This mutual arrangement of the discrete elements is preserved during the movement of the full load-bearing organs as a whole. The latter are interconnected by a T-shaped. And in cross section are perforated jumpers 15, the number of which is half the number of pairs of discrete elements.

At the ends of the jumpers there are one hole each for the attachment to the hinges of the load-carrying bodies, on which the jumpers are mounted with a step through each even hinge, i.e., only on those rollers that come in contact with the upper rails on the sections of the zigzag position of the discrete elements in the vertical plane.

lia mid T-shaped jumpers rigidly fixed rectangular plates

with an upper elastic coating 16, for example, a layer of rubber. At the ends of the T-shaped jumpers, the U-shaped plates 17 with bent edges, grasping the horizontal flanges of the jumpers, are loosely worn with the possibility of longitudinal movement. The upper plane of the U-shaped plates has the same direction: K | ryty, kaki-rectangular plates. The total number of plates on one jumper is equal to the number of rows of blanks on the device. The free end of the horizontal shelf of the U-shaped plate, facing outward, is elongated, placed in motion over the upper rails and has a hole in which the pins 18 are rigidly fixed. The pins fit into the groove of the upper rails with the possibility of contact and sliding along the horizontal guiding surface m 19, made on the top

plane top copy rails.

In the bottom part of the upper rails, along their entire length, a series of holes 20 are made, intended to allow the building material waste to freely wake up through these holes.

A safety ruler 21 with a small gap of 0.5–1.5 mm under the upper row of jumpers is mounted along the axis of symmetry of the device. It serves to prevent breakage of the jumpers in case of overload and is fixed with its ends on the cases of 22 gear pairs 23. The gear pairs are mounted on shafts mirroring each other and are interconnected by an intermediate shaft 24 with a compensating sleeve 25.

The press table with the molds in which the blanks are located, the passage over the device for receiving the blanks, is stopped so that the blanks are positioned each

above plates 16 and 17 with some gap between it and.

The blanks ejected from the press lie on the upper planes of the plates 16 and 17 with an elastic coating that protects the blanks.

from damage. Then turn on the drive of the periodic Turning of the drive shaft 1, from which the rotation is transmitted by means of gears 23 and the intermediate shaft 24 to the driven shaft 2. The shafts 1 and 2 rotate simultaneously and rotate the disks 6 that sit on them, which move the load-carrying units 7 s jumpers 15 and mounted on the last plates 16 and 17.

In this case, the workpieces smoothly move in the longitudinal direction from the drive shaft 1 to the follower 2. In the further movement, the distance between the bridges 15 decreases and the rows of workpieces approach each other. Convergence

a series of blanks is completed in the area of horizontal arrangement of the lower output rails 12. In the process of their movement, the load-carrying bodies 7 undergo form change. Pairs of articulated elements 8 after the passage of the place

receiving blanks form a broken zigzag line relative to each other, the shape of which stabilizes towards the end (Slanted lower slats 13 and then, going out of the space between the slats 10 and 12, the rollers 9 are gripped by a tooth; the drives 6 of the driven shaft 2 and elements 8 are transferred in distribution, to the lower return branch.

At the same time, the vertical pins 18 slide along the guide surfaces 19 of the upper copying rails 10 and move the plates 17 along the webs 15, bringing the rows of blanks closer to providing a predetermined gap between them. After passage of the tongs 18 along the guides along the section of the formation of the layer of blanks, the plates 17 are moved apart, and the plugs 18 exit from the guides.

The device allows simultaneous shearing of the blanks in two mutually perpendicular directions and forms a layer of predetermined dimensions consisting, for example, of eighteen blanks.

After passing in the opposite direction along the lower branch of the parts carrying the bodies 7, the pins 18 fall into the guide grooves 19 from the left curved end of the rails 10.

The process takes place continuously.

The removal and cleaning of the formed layer from the device is carried out in a known manner, for example, using the simplest group gripping body.
