Description

The proposed utility model relates to the field of machines (also often referred to as lines) that provide assembly of a label with a previously made container (for example, a glass, mainly a cardboard or plastic / polypropylene glass). By assembly in this text is meant the process of combining a label on a container and then fixing the label. The label located on the container (wrapped around the glass and fixed on it in some way) is mainly designed to prevent burns to the consumer's hands when using the container with hot liquid later, and also allows you to decorate the container with a label with a high quality seal applied on it. Labels are predominantly made of cardboard or similar flexible materials.

Further, in the text of the description and formula, the term “capacity” is used along with the term “glass” - since the predominant use of the proposed model is the use of the machine in relation to glasses, which, however, does not limit its purpose, and the use of the machine can be carried out in in relation to other containers, for example, closed on both sides or, on the contrary, in relation to products that do not have end sides (bottom), at the time of its assembly with a label; the terms “assembly” and “combination” are used along with the term “wrapping”, as they are more general and involve not only wrapping, but also fixing the label on the container.

To implement such an assembly of a container with a label, various machines (lines) are used.

Verpackungstechnik GmbH (патент Германии DE 10054727 (А1), 2002.05.08 г). Принцип работы данной линии (фиг.1-3) следующий.The CBU - DES line of the company’s production was chosen as the closest analogue

Verpackungstechnik GmbH (German patent DE 10054727 (A1), 2002.05.08 g). The principle of operation of this line (Fig.1-3) is as follows.

The assembly line for a container with a label consists of the main table 1, a feeder for non-wrapped containers 2, a feeder for a label 3 and a conveyor for a wrapped container 4.

Wrapped glasses are fed to the feeder in the form of a continuous stack and, using a conveyor belt, are transported to the main table. On the main table is an octagonal vacuum case with mandrels 5. The glasses are sequentially, one at a time, put on these mandrels, after which the octagonal case rotates 45 °, and the mandrel enters the label wrapping area around the glass.

The label in the form of a stack is inserted into the cartridge above the label-feeding device by the feeder, then it is removed from the stack by vacuum grippers and sent along the tape of the feeder to the glass wrapping area. While driving on the feeder, glue is applied to the label.

In the wrapping zone, the label is pressed to the glass with the lower clip 6, after which it is wrapped with side clips 7 and 8 around the glass, at the junction of the opposite edges of the label it is fixed with the upper clip 9.

Then the octagonal case again discretely rotates through an angle of 45 °.

After gluing the label, the glass remains on the mandrel until it enters the removal zone of the wrapped glass. The wrapped glass is removed (blown away by air) from the mandrel to the conveyor, gets into the stack, moves along the conveyor of the wrapped glass to the packing table and then is packed.

During the operation of this line, several shortcomings were identified. The first and main disadvantage is that the motion control by the lower clamp unit 6, the upper clamp unit 9 and the wrapping unit, which includes the clamps 7 and 8, is carried out exclusively mechanically, namely by moving the mechanical motion control unit for each of the nodes along the metal guide (on drawings), consisting of a copier 10, directly related to the movement of the main drive 14. Moreover, individual adjustment of the movement of each of the clamps 6, 7, 8, 9 is possible, but since the position settings of all imov set in one piece, you must fabrication, inspection and adjustment of the new part. In this case, if, for example, it is necessary to change the motion setting of only one of the clamps, leaving the motion setting of the remaining clamps unchanged, it is still necessary to change only one surface that sets the motion, and the rest, repeating, change the entire part (metal guide) as a whole. Such a change is a complex technological step, which greatly slows down the reconfiguration of the machine if necessary.

The second disadvantage is the impossibility of changing the closing order of the side clips 7 and 8 and, accordingly, changing, if necessary, the direction of overlap labels from right to left (Fig. 4). This feature is required for the implementation of complex non-standard stickers in which the sticker is not an ordinary strip of cardboard with a printed pattern, but is supplemented with various design elements, which requires the ability to overlap both clockwise and counterclockwise.

The technical result of the proposed technical solution is

increasing the efficiency of the machine, including increasing the speed of the machine by reducing the time it takes to feed the label, increasing the accuracy of positioning the label before gluing;

 the possibility of precise label positioning for any shape of the wrapping capacity and various forms of labels, provided, unlike the closest analogue, without the need to disassemble most of the machine and without replacing the complex and expensive part that mechanically sets the movement of all the clamps - a copier (which must be separately made before );

 the possibility of changing the direction of overlapping labels.

The specified technical result is achieved due to the next execution of the machine.

A container assembly machine with a label, comprising a main table 1 with a housing with mandrels 5 placed on it, a non-wrapped container feeder 2, a label feeder 3, a wrapped container conveyor 4, a lower clamp 6, side clamps 7 and 8 and an upper clamp 9; wherein the lower clamp 6 further comprises a separate actuator 12, the side clamp 7 further comprises a separate actuator 15, the lateral clamp 8 further comprises a separate actuator 16, and the upper clamp 9 has a separate actuator 11.

Each of these individual drives 11, 12, 15 and 16 consists of at least a mechanical rod 17 and a moving element and has a separate control that is not related to controlling the movement of the housing with mandrels 5 of the main drive 13 and the movement of the remaining elements of the machine, number of other individual drives; in other words, a drive, for example 12, can be controlled (and carry out its function) regardless of the position of the drive, for example 13 or 11, and, moreover, regardless of whether at least one of the other drives (or all drives together) or not, any of the drives is independent, controllable and separate from other drives.

Each of these individual drives 11, 12, 15 and 16, all together or separately, can be implemented as one of the options for the following types of drives:

 pneumatic drive;

 hydraulic drive;

 servo-driven electric cylinder;

 electric cylinder with step drive.

In the case of using a pneumatic actuator from the control processor, implemented as part of the machine, an electrical signal is supplied to the distributor coil, and compressed air (from the tank, (not shown in the drawings) can be implemented as universal, serving two or more machines, or individual for one machine) is fed in a given direction and with a given force into the pneumatic drive; in the case of using a hydraulic actuator from the processor, an electrical signal is supplied to the distributor coil and, under liquid pressure, is supplied in a given direction and with a given force to the hydraulic actuator. In the case of using the electric cylinder from the control processor, the electric signal is supplied to the servo drive control unit, and from the block to the servo drive itself.

The aforementioned control processor may be implemented as one, configured to control all drives, or each drive individually, or together several of these drives; and in the form of several separate independent or dependent processors, each of which controls one or more drives, and communication between such processors can be implemented.

The drives are controlled by the control processor in accordance with the software installed in this processor.

The specific type of drive used depends on and is selected depending on the task being solved and ease of execution, the presented list is not closed and, theoretically, other, more specific types of drives can be used in the proposed machine.

The relative arrangement of the drives and the schematic view of the connection with the clamps are shown in FIG. 5-8.

The connection between the drive and the clamp is carried out mainly by mechanical traction 17.

The presence of a separate drive 12 at the bottom clip 6 allows you to set the moment the clip starts and stops from the control processor, which, in turn, allows you to achieve more precise settings for the movement and position of the clip 6, that is, as a result of the location of the label relative to the surface of the container.

To ensure label wrapping around the container, separate drives 15 and 16 of each of the two side clamps are used (7 and 8, respectively). This embodiment of this machine node allows you to set the moments of the beginning of movement and stop of each of the clips 7 and 8 from the control processor, which leads to more precise settings for the movement and position of the clips, that is, as a result of the location of the junction of the opposite edges of the label. Also, the presence of independently controlled separate drives 15 and 16 allows, by setting the sequence of their operation, to change the direction of overlap of the label (Fig. 9) at the junction from left to right or from right to left without mechanical reconfiguration of the machine.

Similarly to the lower clip with a separate drive, the presence of the upper clip 9 of a separate drive 11 allows you to set the moment of start of movement and stop of the clip from the control processor, which, in turn, allows you to achieve more precise settings for the movement and position of the clip 9, that is, as a result of the location labels relative to the surface of the container.

Thus, with this implementation of the machine, separate control of the clamps allows you to configure and control each movement of each of the clamps separately. For example, at the first stage, at a low speed, in order not to disturb the positioning of the label relative to the container, press the label to it. Then, at the second stage, set the side clamps to such a program (and speed) of movement, in which at the beginning and at the end of the movement they move relatively slowly so as not to disturb the positioning of the label relative to the container (since at this stage it is pressed only by the lower clip and enough it can easily be shifted from the desired position), and in the main phase of the movement, the speed of the clamps increases, which allows to reduce the cycle time (saving this time, which is a fraction of a second, is insignificant for the process one tank, however, in the production of tens of thousands of products it is already hours, which is a serious savings). In addition, the presence of several independent from each other drives in the machine allows its more flexible adjustment, which prevents a significant part of positioning errors, which leads to fewer machine stops and an increase in its productivity with fewer rejects. Another effect of this solution is that tanks can be in production, firstly, with individual geometry and, secondly, from different materials that differ in their mechanical properties; the same applies to a label compatible with the container. Accordingly, in each such case, the optimal mode of movement of the clamps will differ from the optimal mode for a different geometry of the tank and other conditions. The proposed solution makes it easy, by reprogramming the speed and sequence of operation of the drives and, accordingly, the movement of the clamps, to select such an optimal mode for each option “container-label” individually, without resorting to the expensive and impossible operation without preliminary complex calculation work to change the mechanical setting of all clamps copier, inevitably accompanied by a stop, disassembly and testing of the entire machine.
