Description

the end of the label is guided to the surface of the item; the pressing mechanism equipped with a roller; a mechanism that supports the paper substrate during the transfer of the label onto the rotating object and adjusts the tension applied to the label by rotating the object; a reel that supplies the labeling device with labels, and a mechanism that rolls up an empty paper base. The roller of the mechanism takes the working position only when gluing the free ends of the label on the surface of the object. When gluing on the central part of the label, the roller does not function.

The disadvantages of all the above labeling devices are the presence of the tape transporting the labels, since a special device is required to unwind this tape, difficulties in disposing of these tapes, and the need for complex tracking devices that detect the presence of any labels on the speed control labels. movement of the carrier tape in order to synchronize its speed with the speed of objects in order to ensure the correct transfer of the label to the object.

A device for applying labels is known, comprising a feeder for continuously feeding a long labeling tape into the cutting mechanism, and feed rollers for feeding the labels cut to the required length by the cutting mechanism to the drum to support them. After applying glue to a drum-supported label, the label is glued to the labeling vessel, the cutting mechanism does not completely cut the label from the tape, leaving uncut the parts whereby the back end of the cut label is connected to the front end of the roll tape. The feeder of the labeling tape and the rollers for feeding the cut labels have different feed rates, so that the remaining uncut connecting parts are cut by the tension applied to the label. As a result, a continuous direction towards the feed rollers is formed at the front end of the roll belt.

The disadvantage of this device and the method of labeling realized with the help of it is the need to prefabricate a tape from a continuous series of labels with labels, and the presence of a tracking device and

complex tape feed rate control system so that the tape cut takes place exactly in the right place between the labels.

A disadvantage is also the need to transport these labels from the printing house and store on tapes (rolls).

The purpose of the invention is the expansion of technological capabilities.

This goal is achieved due to the fact that the device is equipped with a printing mechanism for printing the requisites of the labels on the paper tape;

The paper tape cutter, the label cutter, is kinematically connected to each other and to the printing mechanism, with the latter positioned in front of the glue dispenser in the feed direction of the paper tape, and the label cutter is mounted to cooperate with the labeling drum. The paper feed mechanism, the glue applicator, the labeling drum, the label cutter and the printing mechanism are interconnected via a chain drive. Printing mechanism

consists of a cylinder and offset rollers mounted with the ability to interact with it.

The drawing shows the device

for labeling items.

The device for labeling objects consists of a feed mechanism 1 with a roll of clean paper tape, pulling rollers 2, a printing mechanism made in the form of a blanket cylinder 3, which interacts with the supporting and rolling rollers 4 and 5 of the applicator 6, the cutting mechanism 7, the labeling drum 8, covered by the strapping belts and provided with openings communicating with the vacuum system (not shown in the drawing), a roller conveyor 9, feeding objects 10 with a uniform pitch from the drum 11 with the cells and 12, equipped with a fence 13 and a bunker 14 with objects 10.

Rollers 5 rollers interact with paint on cylinders 15 placed in baths 16 and squeegees 17, which remove excess paint. Above the roller conveyor 9 is also mounted a massaging belt 18.

The device for labeling objects works as follows.

Objects 10 (ampoules, vials), loaded into the hopper 14, under the action of the force of weight are lowered down and captured by the cells 12 of the drum 11 carrying them on a roller conveyor 9. The barrier 13 prevents the objects 10 from falling out of the cells 12 of the drum 11. The roller conveyor 9 delivers items 10 with the same step to the labeling drum 8.

At the same time, the pull rollers 2 unwind the blank paper ribbon from the roll of the feeding mechanism 1 and feed it to the offset cylinder 3, which interacts with the tape without slipping. The cylinders 15 pick up paint from the baths 16, the surplus of which is removed by squeegees 17 and transfer it to roll rollers 5, also equipped with squeegees 17 and transferring paint to the offset cylinder 3. The offset cylinder 3 paints the print on the tape supported by roller 4, i.e. we receive the ready labels supplied with all necessary requisites.

Next, a tape consisting of a continuous row of labels is applied on the back side with glue by mechanism 6, and it goes to labeling drum 8, where each label is cut off from tape by mechanism 7, the cut label is held on labeling drum 8 by vacuum.

The drum 8 transports the label to item 10, to which it is facing with the side smeared with glue, the vacuum is turned off, and the ironing straps press the label to item 10. Next, item 10 with the label conveyor 9 is fed to the tallying strap 18, which tightly presses the label and fixes it on item 10.

The proposed device allows to simplify the design due to the use of

rigid kinematic connection instead of a complex tracking system and control of the feed speed of the tape.

The expected economic effect from the implementation of the invention will be 3.7 thousand rubles.
