Description

The invention relates to equipment for packing various products and products into film, in particular poultry tuchke, and can be used in the food industry. The purpose of the invention is to increase operational reliability.

The drawing shows schematically a device for applying adhesive tape to the necks of the packages, front view.

The device for applying the adhesive tape includes a bed 1 on which the coil 2 for the adhesive tape is mounted, a looper consisting of two rollers 3 and 4, a knife 5 for cutting the package neck, a knife 6 for cutting the adhesive tape mounted on an axis 7 sec. rotation, a clamp 8 of the end of the adhesive tape, a device for gripping and tensioning the adhesive tape, including a G-shaped slide, on which a rotating presser double shoulders lever 10 is fixed. The slide 9 is mounted in guides 11 mounted above the looper.

Clamping pin 10 is mounted to rotate on the axis 12.

The roller 3 of the looper for forming statutes can be rotated on axis 13, and roller 4 is fixed on rod 14 so that it can rotate on axis 15 and deflect relative to axis 16 by spring 17. on the plate 19. The L-shaped slider 9 is attached to the protrusion 20. The lever 10 has a curved shape and is equipped with a clamp 21 on one shoulder, and its other arm is bent at an angle to interact with the stopper 22 fixed on the frame 1 and the slot 23 . Slider 9 is associated with return load 24.

The device works as follows.

The adhesive tape from the coil 2 is pulled under the roller of the lock 8, resting on the plate 19, up to the knife 6 and cut off its end. In the initial position, the double-arm lever 10 with one shoulder is fixed under the limiter 22, and the other its shoulder with the clamp 2 is raised above the slider 9.

The mouth of the package manually or otherwise pushed into the slot 23.

The neck of the package oce (| Güdzhaet while the lever 10 from the limiter 22. Next, moving the neck over the slot 23, act on the protrusion 20 of the slide and push it along the guide 11 to the end of the adhesive tape that lies freely on the knife edge 6. The slide 9 at it moves the knife 6 mounted on the axis 7 and passes over it under the adhesive tape. The package neck, approaching the upper part of the slot 23, releases the lever 10. It turns on the axis 12, At the same time, the pressure 21 is lowered onto the adhesive tape and presses it to the crawler 9. At the highest point e slits 23 neck packet frees the projection 20 of the slider 9, slider 9 while holding clamp 21, the adhesive tape under the action of the load 24 are returned to the original position. In this case, the lever 10 enters his shoulder by limiter 22 and the clamp 21 is lifted, freeing the end of the adhesive tape.

Moving down through the slit neck of the package, sticky tape to it. The end of the adhesive tape is fixed by sticking on clamp 2, in the area between coil 2 and clamp 21, the tape lies freely on the knife edge 6. When you move the tape down with the neck, it is pulled and cut off by the knife 6. in the looper, where a loop is formed, due to the passage between a rotating roller 4 mounted on an axis 13 and a roller 3 fixed on a brush with the possibility of rotation on an axis 15 and a deflection under action about an axis 16,

After this, the knife 5 cuts off the extra part of the neck (| package.

The use of the proposed device makes it possible to ensure a twofold increase in productivity by 1.2 times and to reduce the consumption of adhesive tape to 10 m per 1000 packages.

Execution of the proposed device with a clamping device for gripping and tensioning adhesive tape installed above the looper in guides and fitted with a L-shaped slider with a swiveling two-arm clamp mounted for reciprocating and shifting and installing a knife for detaching adhesive tape can be rotated, eliminates slippage of the neck of the package along the tape, as the adhesive tape before it is applied to the neck of the package is moved to its original position bloom over the looper and is in a strained position. When the neck moves along the slot to the looper, the tape is caught. This ensures uniform coverage of the neck on both sides with adhesive tape and good loop quality. Thus, it increases reliability in operation when applying adhesive tape to r eagles of packages.
