Description

The invention relates to food, chemical, pharmaceutical industries, in particular to labeling machines for applying labels from continuous label tape to cylindrical containers.

In modern production conditions, there is a need to apply labels of different heights on cylindrical containers, as well as the need to apply labels at different distances from the bottom of a cylindrical container. At the same time, equipment retooling should take a minimum amount of time, require a minimum of effort and qualification of the maintenance staff.

For the labeling of cylindrical containers, in particular bottles, labels of various heights are used. To ensure accurate labeling of the container, the height of the drum of the labeling machine should be equal to the height of the label.

A labeling machine is known from the prior art, comprising a conveyor for receiving and withdrawing cylindrical containers, for example bottles, a device for separating them, a drive vacuum drum, a device for supplying continuous label tape from a bobbin to the surface of a vacuum drum, a device for applying glue to a label tape and subsequent cutting it into individual labels, a device for rolling labels onto a container, a device for heating glue, as well as a drive, synchronization and regulation device tires, and in the container for the preparation of glue there is an adhesive pump for feeding glue to the surface of the glue drum, in which, like in the glue drum, there are built-in devices for heating the glue (see German Utility Model Patent No. 202005002793, B65C 3/16, 04/21/2005).

Closest to the technical nature of the claimed solution is a labeling machine containing a conveyor for the entry and exit of cylindrical containers, such as bottles, a device for separating them, a drive vacuum drum, a device for feeding continuous label tape from a bobbin to the surface of a vacuum drum, a device for applying glue on a label tape and its subsequent cutting into separate labels, a device for rolling a label onto a container, a device for heating glue, and also devices drive, synchronization and regulation of the machine itself, and in the container for the preparation of glue there is an glue pump for supplying glue to the surface of the glue drum, in which, like in the glue drum, there are built-in devices for heating the glue, the device for rolling the label is made flat and covered with elastic material, for example rubber (see patent RU 2326030, B65C 3/16, 05/11/2006).

A common disadvantage of the known technical solutions is the need to change the drive vacuum drum in case of a change in the height of the applied label, which requires additional labor and time. Another disadvantage of the known solutions is the limitation of the function of the device, because there is no possibility of applying labels at different distances from the bottom of the container.

The objective of the invention is to eliminate this drawback, making it possible to apply labels of different heights at different distances from the bottom of the tank.

The technical result of the invention is to expand the technological, functional capabilities of the machine, allowing the application of labels of different heights at different distances from the bottom of the tank, without interrupting the process and maintaining high performance labeling machine regardless of the height of the applied label and the distance from the bottom of the tank.

The technical result is achieved in that in a labeling machine containing a frame on which a conveyor is installed for the entry and exit of cylindrical containers, for example bottles, a device for separating them, a drive vacuum drum, a device for feeding continuous label tape from a reel to the surface of a vacuum drum, device for applying glue to a label tape and then cutting it into separate labels, a device for rolling a label onto a container, a device for heating glue, and also devices drive, synchronization and regulation of the machine itself, and an adhesive pump is installed in the container for glue preparation to supply glue to the surface of the glue drum, in which, like in the glue drum, there are built-in devices for heating the glue, the device for rolling the label is made flat and covered with elastic the material, for example rubber, according to the invention, the drive vacuum drum is equipped with a set of removable rings or disks with collars of different heights, and the outer diameter of the ring or disk is equal to the outer diameter of the drum on, and the conveyor for the entry and exit of containers has a height adjustment mechanism, while the lower part of the machine frame has bushings with screw-in supports for adjusting the machine height in order to fit the conveyor working surfaces for the entry and exit of cylindrical containers with the working surfaces of the previous and subsequent technological line of machines. In the case of using the ring, its inner diameter is 0.85-0.98 of the outer diameter of the drum.

The set of features contained in the independent claim is not known from the prior art, which indicates the conformity of the claimed technical solution to the patentability criterion of "novelty."

According to the scientific, technical and patent literature, no combination of features has been found that allows us to solve a problem that could not be previously solved by known technical solutions. In the prior art there are no solutions having features that match the distinguishing features of the proposed technical solution, which indicates that the technical solution meets the patentability criterion of "inventive step".

The compliance of the proposed solution to the patentability criterion of "industrial applicability" is due to the fact that the proposed technical solution is efficient and it can be used in the food, chemical, pharmaceutical industries.

In the drawings, for clarity, only those details are presented that are necessary for understanding the essence of the invention, and the accompanying elements, well known to specialists in this field, are not presented.

The base of the machine is a frame 1 (Fig. 1), on which a conveyor 2 (Fig. 2) is installed for the entry and exit of cylindrical containers 3, for example bottles, a device for separating them 4, a drive vacuum drum 5, a device for feeding continuous label tape 6 from a bobbin onto the surface of the vacuum drum 5, a device for applying glue to the label tape 7 and a device for its subsequent cutting into individual labels 8, a device for rolling the label onto a container 9, a container for preparing adhesive 10, inside which the device is installed your for heating glue, with an adhesive drum 11, inside of which there is also a device for heating glue, as well as a drive, synchronization and regulation device for the machine itself.

The drive vacuum drum 5 is equipped with a set of removable rings 12 (Fig. 3) or disks with beads 13 (Fig. 5) of different heights L, and the outer diameter of the ring or disk D _to (Fig. 3) is equal to the outer diameter of the drum D _b (Fig. 7). The drive vacuum drum 5 is made with the possibility of installation and fixing on its upper surface of the ring 12 or disk to provide additional increment of the drive vacuum drum 5. The design of the ring or disk assumes a shoulder 13, the height L of which is selected so that the sum of the heights of the drum N (Fig. . 7) and the shoulder L of the ring or disk, i.e. H + L (FIG. 7) was equal to the height of the label T (FIG. 10). The retention of the upper part of the label on the vertical surface of the ring 12 or disk, on which there is no vacuum, is ensured by the free electric charge resulting from the friction of the label tape on the vertical surface of the ring or disk.

The conveyor 2 for the entry and exit of the containers has a height adjustment mechanism, which contains a screw 14 (Fig. 8), a plate 15 with grooves, nuts 16 (Fig. 9) on the axes 17 for mounting the conveyor to move the conveyor 2 in a vertical plane 2 to the frame of the machine 1. To avoid violation of the horizontal position of the conveyor 2 when moving it in a vertical plane on the frame of the machine 1 left and right, as well as on the frame of the conveyor 2 are installed pairs of carriage - guide 18 (Fig. 9).

In order to align the working surfaces of the conveyor 2 for the entry and exit of cylindrical containers with the working surfaces of the previous and subsequent machines in the technological line, the lower part of the carcass 1 of the machine has bushings 19 (Fig. 1) with screw supports 20 for adjusting the machine in height.

When used as an increment of the ring 12, its inner diameter equal to 0.85-0.98 of the outer diameter of the drum is optimal.

Labeling machine operates as follows.

When changing the height of the label T (Fig. 10), a ring 12 or a disk is mounted on the drive vacuum drum 5. The height L of the shoulder 13 is selected so that the sum of the height of the drum N and the height of the shoulder L, i.e. H + L was equal to the height of the label T.

When changing the distance from the bottom of the container to the lower border of the label S (Fig. 10), the position of the conveyor 2 is changed. The conveyor 2 is moved in the vertical plane using the screw 14 (Fig. 8) along the grooves of the plate 15, after loosening the nuts 16 (Fig. 9) on the axes 17, which are used to mount the conveyor 2 to the frame of the machine 1.

To ensure alignment of the working surface of the conveyor 2 with the working surfaces of the previous and subsequent machines in the production line, the height of the carcass 1 of the machine is adjusted by means of supports 20 screwed into the bushings 19.

After the actions performed, the machine is started.

When changing the label height, the machine adjustment process is repeated as described above.

The use of the claimed labeling machine will expand the technological capabilities of the labeling machine, avoid the need to replace the drive vacuum drum when changing the height of the label, will provide the ability to apply labels at different distances from the bottom of the tank.
