The invention relates to methods and equipment for packing mainly loose fine dust products into cardboard, polymeric or metal drums, boxes and containers with a film liner and can be used in the chemical and related industries.

The aim of the invention is to increase the tremendous and cost-effective packaging by more fully filling rigid containers.

The method of packing bulk materials includes securing the liner of film material to the filling nozzle, placing the loose part of the liner in a rigid container, attaching the container to the filling nozzle, feeding the product into the liner while weighing it, freeing the container from the attachment to the filling nozzle, not removing it from the liner , compacting the product in the insert by shaking the container, removing the insert from the filling nozzle, sealing the insert, placing it completely in a rigid container and e In the method of sealing of the liner and the rigid containers are chosen such that the liner dimensions in cross-section, and the height greater than the corresponding dimensions of the container

Fig. 1 shows the device, a general view, Fig. 2 shows a section A-A in Fig. 1, Fig. 3-8 shows a view B in Fig. 1 (various positions of the mechanisms), Fig. 9-

14- separate steps of the packaging method.

A device for packing granular products into rigid containers, for example, in carriage-wound drums, includes conveyor 1 supplying empty drums 2, conveyor made in the form of roller table 3, and receiving conveyor 4 discharging drums 2 with a filled liner 5 3, a filling nozzle 6 is connected with weights (not shown) with a device 7 for securing an insert 5 thereon, made, for example, in the form of two clamps 8, mounted so as to move one towards the other and back from the pneumatic cylinder Ditch 9 and with the ability to interact with the outer surface of the filling nozzle 6 Fixture 10 for reinforcing rigid containers on it is also mounted on nozzle 6 and made as a pair of interlocking /. -shaped levers 11 Each pair of levers 11 is installed with the ability to interact with the corresponding clamp 8 Above the filling nozzle 6 there is an outlet nozzle 12 of the brutto-weighing batcher

Under the roller 3 on the shock absorbers 13 fixed frame 14, equipped with a vibrator

15 On the frame 14 with the possibility of reciprocating movement in the vertical plane from the drive 16, a plate 17 is installed with supporting plates 18, which are arranged parallel to the rollers 19 of the roller table 3 and with the possibility of passage between these rollers 19 In order to prevent the plate 17 from shifting (rotating) in the horizontal plane Four fingers 20 are fastened on it, which are slidly slid through the holes in the frame 14. On the supporting plates 18 on opposite sides of the roller table 3, rotary locks 21 are fixed, which pairwise pivotally connected with the respective actuators 22, mounted on the plate 17. Pneumatic jacks are used as the actuators 16 and 22.

The device works as follows. Empty open drum 2 (rigid container) is fed by conveyor 1 to roller table 3 and last under filling nozzle b (Fig. 1 -3). Insert 5 of film material, the dimensions of which in cross section and in height exceed the corresponding dimensions. drum 2 is placed in drum 2 (FIG. 9) at the position of the conveyor 1 or directly5 but at the position of the roller table 3 The upper open end of the liner 5 is put on manually or automatically on the filling nozzle 6 At the same time the clamps 8 of the device 7 and enclosure 10 for fastening packaged drum 2 on additional filling nozzle 6 is opened Then drive 16 is turned on and lifts plate 17. At that, support plates 18 placed on plate go upwards between rollers 19 of roller table 3, abut against bottom of drum 2 and raise it for some a distance 5 S sufficient to feed the bottom of the drum 2 / -shaped levers 11 of the tool 10 After the lifting of the drum 2 has been completed, the pneumatic cylinders 9 of the tool 7 operate and clamp the clamps 8

Q the neck of the liner 5 on the filling nozzle 6. The released (. -Shaped) levers 11 of the tool 10 rotates towards each other under the force of gravity and is fed by the lower ends under the drum 2 (Fig. 5)

5 After this, the reversing drive 16 is again switched on and lowers the plate 17 with the supporting plates 18 to the initial position. At that, the drum 2 hangs on the V-shaped levers 11 (FIG. 6) Fingers 20 fixed on the plate 17 and passed through the frame holes 14, perform a guiding function in the reciprocating movement of the plate 17.

A gross weighing dosing device is switched on and from its outlet pipe 12 to the filling pipe 6 and, accordingly,

in the insert 5, placed in the drum 2. attached to the filling nozzle 6, the bulk product is fed. At the same time, when weighing the product supplied to the container

is corrected for empty drum weight with liner. The delivery of the product continues until the set mass of the dose is inserted in the insert 5. In this case, the level of the collected dose of the bulk product may exceed the position of the upper edge of the neck of the liner and be located in the loading port (Fig. 10).

After reaching a given packaged dose of product, the actuator 16 is turned on and re-lifts the plate 17 with the supporting plates 18. At the same time, the supporting plates 18 are brought under the bottom of the drum 2 and raise it by a certain amount (Fig. 5), releasing the L-shaped levers 11 devices 10. Drives 22 are turned on, which also use pneumatic cylinders, and rotate the latches 21 until they stop against the side surface of the drum 2, thereby clamping (fixing) the drum 2 onto the surface of the support plates 18 (FIG. 7). There is a recess (zig) near the bottom of the drum, into which the clips 21 are put into place. The vibrator 15 is turned on, from which the vibration is transmitted to the frame 14 mounted on shock absorbers 13 connected to the frame 14, plate 17 to the supporting plates 18 and, accordingly, to the drum 2 and the product found in it. By means of the three, the product is compacted, and its level is lowered (Fig. 11) below the upper level of the drum 2.

After the process of sealing the product is completed, the vibrator 15 is turned off, the pneumatic cylinders 9 of the device 7 are activated and the clamps 8 and /, the shaped levers 11 of the device 10 are retracted in opposite directions (Fig. 8). The pneumatic cylinders 22 are then activated, and the drum is released from catching the latches 21. The actuator 16 is turned on, lowering the plate 17 with the supporting plates 18 to the lowest position, and the drum 2 with the product is installed on the rollers 19 of the roller table 3 (Fig. 3) and is output to the receiving conveyor four.

On the receiving conveyor 4 (Fig. 12), a neck is formed at the liner 5, on which a sealing seam is formed with the help of the welding tool. Next, the neck of the liner 5 is filled inside the drum 2, it is covered with a lid (Fig. 13), which is sealed (secured), for example, by means of a pressure profiling device (Fig. 14). Ready packaged drum 2 with a sealed liner 5 enters the warehouse.

Due to the use of prekkp; to-we of methods and devices for packaging, a considerable density and cost-effectiveness of packaging is achieved due to the high degree of filling of the internal volume of rigid containers (drums) with high accuracy of dosing. This ensures a high degree of automation and ease of maintenance due to the elimination of dust in the workplace.
