The invention relates to packaging machinery, in particular, to devices for packing a group of objects into a shrink film, and can be used in chemical and other industries.

The purpose of the invention is to reduce packaging material and improve packaging quality.

Figure 1 shows the device, front view; figure 2 is the same, side view; on fig.Z - section aa in figure 1; figure 4 is a group of tubes in a sheath of film; on fig.Z - section bb in figure 4.

The device for packing a group of tubes into a shrink film consists of a horizontal conveyor 1 with holders 2 in the form of spring-loaded clothes pegs. Conveyor 1 is connected with a sprocket unit with a drive not shown), and under one of its branches a carriage 3 is installed with vertical partitions 4 dividing it into 5 cells, the number of which is determined by the tube-laying scheme, with the possibility of rotation around the fixed support in the lower parts from the rod 6, rigidly attached at one end to the top of the carriage, and the other to the piston rod 7 of the pneumatic cylinder, one end of which is made in the form of a rack 8, and the other in the form of a ratchet 9. Under the carriage 3 there is an orientator 10, in the top housing parts and which are mounted a series of screw guides 11 with the possibility of turning around its own

At the end of the frame 12, the driver 15 is rigidly fixed for the kinematic connection of the frame 12 with the piston rod 7 of the pneumatic cylinder, its end with the rack 8, through the eccentric 16 mounted on the axis 17, and the wheel 18 s

overrunning clutch 19.

In the lower part of the housing of the orientator 10, a collar 20 of the sleeve former and a device for welding and cutting the film are installed coaxially with it, which includes a movable weld sponge 21 to form a longitudinal seam of the film 22 unrolled from a roll 23 and movable welding sponges 24 to form a cross stitch .

Photosensors 25 and a microswitch 26 are mounted above the carriage 4, as well as a microswitch 27 controlled by the movement of the pneumatic cylinder piston rod 7, i.e. its end with a ratchet 9, through the ratchet wheel 28, on which the pins 29 are mounted.

The tubes 30 are fed from a tubing 31 by a pusher mounted on the latter, which forcefully inserts the tubes 30 into the spring-loaded pegs of the holders 2,

The carriage 3, the orientator 10 with screw guides 1I during operation of the device are installed so that they form a path for passage of only one row of tubes 30. For placing the second row of tubes, the carriage 3 turns, each time the center lines of each cell 5 of the slide 3, the forming screw guides 11 and the feeding screw guides 11 in the first and second rows are made towards each other at an angle (X, so that, when passing by the flat ends, the tubes 30 also turn towards each other, which provides the styling conditions There is an acute angle ft between the flat end of the tube 30 and the horizontal plane, as well as between adjacent rows of tubes 30

The device works as follows.

The tubes 30 installed by the tube 31 into the holders 2 of the conveyor 1 rotating at a constant speed are fed to the carriage 3, the First tube 30, crosses the beam of the photosensor 25, which commands the piston 7 of the pneumatic cylinder to move, while the carriage 3 rotates, and the rack bar 8 rotates the wheel 18 with the axis 17 to the eccentric 16 at a certain angle, and the frame 12 through the leader 15 advances along with the laths 13 and the fingers 14, which turn the screw guides 11 towards each other. At the same time, the other end of the piston rod 7 with the ratchet 9 turns the ratchet wheel 28 by one tooth clockwise.

The first tube 30 is moved by the transport port I to the microswitch 26, which gives a signal to unclench the pegs of the holders 2. The row tube 30, the pad under the action of gravity, passes freely through the cells of the carriage 3, slides along the working surfaces of the screw guides 11 with their flat ends ( one side), turning at an angle of / 3 relative to the horizontal plane, and then falls into the sleeve of the film, welded with transverse and longitudinal seams.

Next, the device operates in the following sequence.

The first tube of the next row intersects the beam of the photo sensor 25, while the cylinder 7 of the pneumatic cylinder moves in the opposite direction, but the frame 12 remains stationary due to the overrunning clutch 19, and the ratchet 9 slides along the tooth of the ratchet wheel 28.

The tube 30 switches the microswitch 26, and the tubes are reset from the decompressed holders 2.

Laying the upper rusa tube 30 is similar to the bottom.

After laying the upper tusa of the tubes 30, the formation of the group of tubes ends.

The formation and laying of the tubes 30 with orientation takes place continuously, and as soon as the second block begins to be grouped the tubes 30 and the piston rod 7 of the pneumatic cylinder moves forward and, consequently, the ratchet 9 turns the ratchet wheel 28 by one tooth, the gauge 29 switches the microswitch 27, which sends a signal to the stretching mechanism (not shown) of the film 22 from the roll 23, the movable jaws 21 form longitudinal sides, and the jaws 24 - transverse seam and the finished package is retracted into the heat-shrinking tunnel for shrinking the film and then cooling it Niemi. I

Next, the cycle of stacking tubes in the film

repeats.

The use of the device will significantly improve the quality of packaging of groups of tubes, and groups of tubes packed in shrink film can be easily folded into a stable stack.

Thus, all mechanisms of the device are arranged vertically so that they form a path for free passage of the tube under the action of gravity, excluding the contact of the outer surface of the tube having a decorative coating with the mechanisms.

In the orientator, the screw guides have an internal diameter slightly smaller than the flat end of the tube so that the screw surface of the guide serves as a support for the flat end, while the tube itself passes freely through the guide without touching its internal surfaces.

The swiveling cassette serves to prioritize the passage of the tubes into the corresponding row of screw guides, which allows for various technological schemes for laying the tubes, for example, the flat ends of the tubes in one direction only or the flat ends of the adjacent rows of tubes towards each other.
