SU427510A3 - DEVICE FOR MANUFACTURING AND FILLING SHELLS WITH CIGARETTES12 - Google Patents

Description

The invention relates to packaging technology, namely, devices for making wrappers and filling them with cigarettes, and may find application in the tobacco industry.

The devices of this designation are known, which include an endless chain conveyor with rods, holders for making wrappers, a conveyor for feeding blocks of cigarettes, a magazine for blanks of shells, a device for folding shells, heating elements and grippers for transferring the shells to the conveyor.

In such devices, each rod consists of two parts - one (main), mounted on a conveyor chain, and the other, movable relative to the first.

The movable part is adapted to be displaced relative to the core for removal of the finished shells.

Such an embodiment of the rods complicates the design of the device, reduces the speed of the conveyor and, therefore, its productivity.

A distinctive feature of the proposed device is that each rod is made in the form of a rectangular parallelepiped with at least one concave longitudinal face.

The device should be equipped with clamps and for sealing the shells made in the form of brushes.

On the fit. 1 schematically shows the proposed device, a side view of the supporting rods; in fig. 2 - rod when receiving the shell blanks, vertical section; in fig. 3 is a diagram of the position of the rod with brushes. in the formation of the shell by “mode

brushes on the side faces; in fig. 4 is a diagram of the end of the formation of the longitudinal bend of the shell; in fig. 5 is a diagram of the position of the rod upon receipt of the finished object. The device contains an endless conveyor 1 for movement by means of a hook 2 of cigarette blocks 3 a device for making and supplying to the conveyor / shells 4. The shells of cigarettes 3 are pushed into the shell 4 with the aid of the stop 5.

The device for the manufacture of shells 4 includes a chain-fed conveyor 7 with drive rods 6 with driven 8 and tension 9 rollers.

Conveyor 7 has two straight sections, where sheath formation occurs. Near the conveyor, a mechanism 10 is assembled for the harnessing of blanks 11, which are housed in the magazine 12. The blanks are retrieved by a pneumatic conveyor 13 and transferred by a segment 14, which then applies glue to certain surfaces:

Each rod 6 is a rectangular parallelepiped with at least one concave longitudinal face 16.

| In the course of the movement of the conveyor 7, devices 16 are mounted for bending the ends of the casing, finger 17 for the stub, and levers 18 and 19 of the casing base. On the other side of the conveyor 7 mounted heating elements 20.

Next to each rod 6, a holder 21 is attached to the chain of the conveyor 7, which serves to act on the glued joint of the sheath.

Below the drive roller 8, a device 22 is mounted for transferring the shells to the conveyor 1. A lever 23 is provided to release the shells from the holders.

The concave faces 15 of each rod 6 provide ready-made shells that are free to sit on the rods, i.e., are easily removable from them.

Shell formation occurs in the following manner.

With the aid of a pneumatic vacuum pump 13, the preform 7 / shell is removed from the magazine 12. Then the segment 14 anosites glue onto certain parts of its surface and places it in front of the next rod 6 with the help of a lever (see Fig. 1). After that, the workpiece bends around the rod and covers its side faces 15. The brushes act on the shells of this (see Fig. 3), pressing it to the edges 15. Then the turf 21 departs from the rod, and the fixture 16 bends the ends of the workpiece (see Fig. 4). A longitudinal seam is formed, to which the holder 21 n fits. At the next stage, the base bends.

shell pr, and using the finger 17 and equalizers 18 and 19.

The shell formed around the rod freely encircles it (see Fig. 5). Then the rod with the finished casing passes by the heating elements 20, and their glued base is fixed. Under the action of the lever 23 on the holder 21, the latter departs, the released shell is shrunk from the rod by the gripper 24. The latter reciprocates in a vertical plane and is equipped with air traps. With ta rod, obo. The breakage falls on the gripper 25, which rotates around an axis and transfers it to the conveyor 1 with its narrow side. Lever 26 turns it over on a wide face, and the casing is ready to receive the next block. The stop 5 holds it in place until a block of cigarettes enters it.
