SU821305A1 - Device for applying adhesive tape onto package necks - Google Patents

Description

The invention relates to equipment for packaging products, mainly poultry carcasses, in a film, and relates to a device for applying adhesive tape to the neck of packages, and can be used in the food industry.

Closest to the proposed is a device for applying adhesive tape to the neck of the package containing a coil for adhesive tape and a knife for cutting the latter [1

This device has a looper made in the form of two rollers mounted with the possibility of reciprocating motion, while one of the rollers is mounted with the possibility of reciprocating motion, and the knife is placed on the other roller. In the device 2Θ, the throat with the tape attached to it is run in the rollers, forming a loop. The disadvantage of this device is that the neck from the moment of contact with the adhesive tape until it is cut into a 25th knife goes a long way, while the operator performs three movements, and therefore the productivity of the device is not high enough. In addition, this device is difficult in its 30 design, which reduces the reliability of its operation.

The purpose of the invention is to increase the productivity and reliability of the device.

This goal is achieved by the fact that the proposed device for applying adhesive tape to the neck of the bag is equipped with an additional coil for adhesive tape, while the coils are mounted on axes mounted in the slots of the plates with the possibility of free rotation and movement, and serves as a looper.

Figure 1 schematically shows a device for applying adhesive tape on the neck of packages, front view; figure 2 - site cutting adhesive tape.

The device comprises coils 1 and 2 for adhesive tape and a knife 3 for cutting the latter.

Coils 1 and 2 are mounted on axes 4 and 5 installed in slots b and 7 of plates 8 and 9 with the possibility of free rotation and movement, and serve as a looper.

Coils 1 and 2 have the possibility of contacting one another in the slot 10, which is blocked by plates 3 and 11 and 12, plate 13 and knife 3, mounted in pairs on axes 14 and 15 and connected with loads 16 and 17. Limiters 18 serve as days for restricting the movement of goods and knife 19 - to cut off the excess part of the neck 20 of the package. ''

The device operates as follows.

The twisted neck of the '20 bag with the product packaged in it is fed through the slot 10 between the coil 10 and 1, 2, in contact with one another adhesive surfaces. To get started, the horses of the tapes of both coils are glued and stretched along the slot 10 down to the knife 3,. at the same time, adhesive tapes cover the neck of the bag. Then, with further movement, the neck with the loop formed on it presses on the plates 11 and 13, which, moving down, bring the plate jq 12 into the passage zone of the tapes glued together to deflect them. With a slight delay, the plate 13, moving down, brings the knife 3 into the working area, and the cuttings are cut off. Further movement of the neck with the adhesive tape superimposed on ** ’ensures that the free part of the neck is cut off with the help of knife 19. Then plate 12 and, knife 3 are returned to their original position under the action of loads 16 and 17.

The proposed device is simple in design, reliable in operation and has high performance.

Claims (1)

11 hours 12, plate 13 and a knife 3 fixed in pairs on axes 14 and 15 and connected with loads 16 and 17. Restrictions for limiting the movement of loads are used by stoppers 18, and knife 19 for cutting off an extra part of the package neck 20. The device works as follows. The twisted neck of the 20 package with the product packed in it is fed through the slot 10 between the coils 1 and 2, in contact 1 C 11 f 1 The model with another adhesive surface. To start the work, the constors of the tapes of both coils are glued together and pulled down along the section 34 down to the knife 3, while the adhesive tapes cover the top of the package. Then, with further movement of the mouth with the loop formed on it, it presses on the plates 11 and 13, which, moving downward, lead the plate 12 to the zone of passage of glued together tapes to deflect them. With a slight delay, the plate 13, moving downwards, brings the knife 3 into the working area, and the pulses are cut off. The next movement of the neck with adhesive tape applied to it ensures cutting off the free part of the neck with a knife 19. Then the plate 12 and the knife 3 return to their original position under the action of weights 16 and 17. The proposed device is simple in design, reliable in operation and has a high performance. Claims An apparatus for applying an adhesive tape to the necks of packages, comprising a coil for adhesive tape and a knife for cutting the latter, characterized in that in order to increase productivity and reliability of operation, it is provided with an additional coil for adhesive tape, wherein the coils are fixed on the axes installed in the slots of the plates with the possibility of free rotation and moving / and serve as a looper.
