(5) DRIVING ROLLGAN FOR ORIENTED PRODUCT FEEDING

I

The invention relates to industrial transport, in particular to driven roller conveyors for oriented feeding of products.

Known for live rolls oriented, supply products containing the frame on which the cage with load-carrying rollers 11.

The design of the roller table provides transportation of products of cylindrical shape of different diameters.

However, the disadvantage of these roller conveyors is that they do not allow to transport products of different profiles, for example, channels, angles, etc.

Known tayuha drive roller conveyors for oriented supply of products, containing a stand and a frame placed on it, the length of which is equipped with horizontal support shafts with pivoting clips arranged on them, on which supporting shafts are mounted with

THEM with load-carrying rollers and C23 asterisks rigidly connected with them.

The clips of these roller tables are made in the form of two discs, on the circumference of which the gruesonesya rollers are located. The drive of the roller table is carried out through a chain which is in engagement with those clutch sprockets, which are in the upper position.

The design of such roller tables is decompressed. It ensures transportation of products of various profiles, while the level of supply of products always remains constant regardless of their profile.

The disadvantage of these roller conveyors is that their design does not allow to adjust the position of products in height, which reduces the functionality of the roller table.

Claims (2)

Meanwhile, in the process of processing and transporting products of different profiles, it is often necessary to change the height of their placement on the roller table, for example, when applying product cutting to a combined shearing press that has cutting holes located at different heights. The aim of the invention is to enhance the functionality of the roller table by adjusting the feed height of the products of various profiles in accordance with the position of the aperture devices. This goal is achieved in that each cage is provided with a block of sprockets mounted on its shaft, at least two of which are connected by endless chains to the cogs sitting on the supporting shafts of the cage, and a third is associated with an asterisk gray clip It is advisable to provide one of the star blocks with an additional star connected to the roller table drive. Figure 1 shows the roller conveyor, side view; in fig. 2 - view A of FIG. one; in fig. 3 - section bb of figure 2; in fig. section bb of FIG. 3; in fig. 5 shows a section of GGD FIG. T. Roller contains a frame 1 with 1W of the frame 2 placed on it, on which the horizontal support shafts 3 are mounted. The shafts k, made in the form of two shoulders, are mounted on the shafts, at the ends of which there are load-carrying rollers 6 on the supporting shafts 5. Clip rollers have the form differing from each other corresponding to the form of the transported products. An asterisk 7 is mounted on the shaft 5 of each carrying roller, and an asterisk 8, 9, U is mounted on the shaft 3 of each cage (fig.O. Two asterisks B and 9 cages are connected respectively by means of chains 11 and 12 with asterisks 7 of this cage, and a third the sprocket 10 is connected by a chain 13 with a similar sprocket of the neighboring cage.If necessary, cages can be made not in the form of double-arm levers, but in some other form, for example, disks, while the number of load-carrying rollers and sprockets on the cage can be more than two . Starter block set It contains an additional sprocket I, connected by a chain 15 to a leading 9 4 star 1b mounted on the output shaft of the gearbox 17 connected to the drive roller motor 18. The frame 2 is movable in a horizontal plane relative to the frame 1. Moving the frame carried out by means of worm gears, each of which consists of a screw .19 and a worm gear 20 of figure 5), mounted on a screw 21, which is mounted in a nut 22 attached to frame 2. The screws are interconnected between An internal shaft 23, at the end of which a handle 2k is fastened, for turning the sleeves on the shafts 3 are mounted worm gears 25 (fig.) interacting with screws 26. The screws 26 of all the sleeves are connected by an intermediate shaft 27, at the end of which a handle 28 is located . To feed the strip material of the live rolls with additional horizontal rollers 29 mounted in bearings 30. On the axis 31 attached to the side of the bed 1. The roll table works as follows. In order to feed the product 32, for example for cutting to a shearing press, the yoke cage is turned into a position that provides the necessary height for the positioning of the supplied products in accordance with the height of the receiving devices. When the drive motor 18 is turned on, the movement through the chain 15 is transmitted to the block of stars and through the chains 11 and 12 to the stars of the 7 load-carrying rollers. At the same time, by means of the chain 13, the movement is transmitted to the block of stars and the load-carrying rollers of the neighboring cage, and from it in a similar way to the other cages of the roller table. If it is necessary to change the height of the supplied products (for example, when changing the profile of the rolled product fed to the cutting in the combined scissors), the clips are rotated to the required position, which is performed by rotating the handle 28. The intermediate shaft 27 is rotated and by means of the screws 26 and the worm gear 25, the rotation is transmitted to the shafts 3 and the clips. To adjust the position of the products across the width of the roller table, the frame 2 is moved in a horizontal plane relative to the bed 1. This is done by turning the knob. The intermediate shaft 23 is rotated, screws 19 with worm wheels 20 and screws 21. Nuts 22, which sit on screws, move along them and transmit movement to frame 2. Thus, the design of the drive roller table allows to transport products of various profiles and provides adjusting the height of the product in accordance with the position of the receiving device, which provides enhanced functionality of the role of the ganges. Claim 1. Driving roller conveyor for oriented supply of a product containing a frame, a frame placed on it and horizontal support shafts installed along it with pivoting clips arranged on them, on which supporting shafts are mounted with load-carrying rollers and rigidly connected them with asterisks, characterized in that, in order to extend the functionality by adjusting the feed height of the products of different profiles in accordance with the position of the receiving devices, each The yoke is provided with a sprocket unit mounted on its support shaft, at least two of which are connected by endless chains with sprockets sitting on the supporting shafts of the given yoke, and a third sprocket is associated with an asterisk of the neighboring yoke block. 2. The rolling table according to Claim 1, which is one of the fact that one of the blocks of asterisks is equipped with an additional asterisk connected to the drive of the roller table. .
