Abstract

Use: packaging in bags of compressed bulk material in the chemical and light industry and in the building materials industry. SUMMARY OF THE INVENTION: The device comprises an intake and outlet conveyors and an orientation mechanism for objects placed between them. The orientation mechanism is made in the form of a gutter with a side guide wall. The chute is made in the form of a surface formed by rotating a rectilinear generatrix at an angle of 90 °. The side guide wall is located on the outside of the groove. The device is provided with a stop to prevent objects from tipping over at the junction of the chute with the discharge conveyor. 2 Il.

The invention relates to a packaging technique, in particular, to devices for packaging in bags of rectangular shaped pieces, for example a bulk material compressed into briquettes.

A device for reloading rectangular shaped pieces, for example, bulk material pressed into briquettes, packaged in bags, contains an intake and discharge conveyors and an orientation mechanism for objects placed between them and made in the form of a forks driven by force. cylinders.

The disadvantage of this device is its low reliability, due to the complexity of the design of the mechanism for the orientation of objects, made in the form of a forks, carried out by the reciprocating rotational movement in two

mutually perpendicular planes. In this case, an exact kinematic coupling of the gripping forks with a diverting and receiving conveyors located at different levels is required.

A device for reloading rectangular shaped pieces is known, comprising a receiving and discharging conveyor to the sealing device and an object orientation mechanism arranged between them and made in the form of a groove with a lateral guide wall and a curved guide arranged above the groove. In this case, a drop bar is fixed at the receiving conveyor at an angle to its longitudinal axis.

A disadvantage of the known device is that it is unsuitable for reloading rectangular shaped pieces, packed in bags, with their installation on the smallest supporting surface.

about

for reliable orientation of the open mouth of the bag relative to the sealing device.

The aim of the invention is to provide a reliable orientation of the mouth of the bag relative to the sealing device by placing the rectangular shaped pieces on the smallest supporting surface.

Achievement of a positive effect — reliable orientation of the bag mouth relative to the sealing device — is provided by the design of the mechanism for orientation of piece objects made in the form of a groove with a side guide wall, while the groove is made in the form of an oblique ruled surface formed by turning the straight line forming an angle equal to 90 °. In the process of sliding along the chute, a piece object, for example a loose briquette bagged in a bag, is rotated around the corresponding forming ruled surface and fed by the smallest supporting surface to a conveyor discharging to the sealing device, and the stop prevents the piece from tipping over at the point of reception on the discharger .

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view.

The device for reloading rectangular pieces of objects includes a receiving conveyor 1 and a discharge conveyor 2 located at different levels and connected to each other by an orientation mechanism of objects 3 made, for example, from a steel sheet, in the form of a groove 4 having the form of an oblique ruled surface formed by rotation of the rectilinear generatrix 5 at an angle of 90 ° and provided with a side guide wall 6 rigidly fixed on the outside of the groove. At the junction of the chute 4 with the discharge conveyor 2, a stop 7 is installed to prevent objects from tipping over, for example, in the form of a sheet of metal bent at an angle of 90 ° and commensurate with the piece object packed in the bag.

The device works as follows.

Pieces 3, for example, briquettes made of rectangular loose material sized 600x400x200 mm and weighing 30-50 kg, placed in bags, for example, are fed from a hydraulic press to a receiving conveyor 1 coupled to an object orientation mechanism along a forming 5 ruled surface. Moving along the receiving conveyor 1, item 3, packaged in a bag, initially hangs over the chute 4 of the orientation mechanism, and when less than half the length of the item remains on the receiving conveyor 1

3, the latter is transferred to chute 4 and begins to slide along its ruled surface. In the process of sliding the subject

0 3 rectangular shape, bagged in contact with the ruled surface of the chute 4 along a straight line - forming 5 of this surface and with respect to the ruled surface the tangential plane.

From the beginning of the slide at each subsequent point in time, the object 3 rotates around the corresponding forming 5 ruled surface

0 of chute 4, being in a position of unstable equilibrium, so that the angle of inclination of the object 3 to the horizon increases from 0 to 90 ° (at the end of the slide). This position of bagged items

5 3 rectangular shape in the process of sliding excludes the possibility of their stopping and jamming. During sliding, objects 3 turn in two mutually perpendicular planes by 90 ° in each.

Side wall 6, rigidly fixed to the outside of the gutter

4, eliminates the rolling of items 3, packaged in bags, with a ruled surface

5 gutters 4, and also contributes to their reversal in such a way that its smallest support surface, i.e. the bottom of the bag, the items 3 packed in the bags are mounted on the discharge conveyor 2.

0 At the same time the open mouth of the bag is directed upwards. Stop 7. Installed at the place of docking of the chute 4 with the discharge conveyor 2, at the reception site of objects 3 packed in bags, is commensurate with objects 3 along the height, prevents them from tipping over and contributes to the orientation of objects packed in. bags open upwards, on a discharge conveyor relative to a sealing device (not shown).
