Description

The useful model belongs to equipment for the production of sausage products, mainly intended for use as part of an automatic line for the production of sausages or sausages.

The linker mechanism performs the function of dividing the continuously filled bar into portions, as well as transporting the finished product to the hanging device or forming table.

Linker mechanisms used in devices for making sausages or anchovies are widely known, for example from |1| or from 21 or from IZ). Known linker mechanisms include the first and second linker tapes with separators attached to them, which are driven by pulleys made with the possibility of rotation on the corresponding vertical axes. Linker mechanisms are equipped with drives, and can also be equipped with various additional elements, depending on the technical problem to be solved.

However, in known sources of information, the mechanism of tension of linker tapes has not been disclosed.

The closest analogue of the useful model is the linker mechanism for the production line of sausages or anchovies by MEMAS (OE) |41.

The known linker mechanism includes a protective casing of the linker mechanism, the first and second guide housings, the first and second linker belts with separators attached to them, the first and second pulleys, made with the possibility of rotation on the corresponding first and second vertical axes, the third and fourth pulleys, made with the possibility of rotation on the corresponding third and fourth vertical axes to bring the corresponding first and second linker tapes into counter-parallel movement, and the first and second devices for tensioning the corresponding linker tapes. Each device for tensioning the linker tapes is a toothed rack of circular cross-section installed in the opening of the guide housing. A spring-loaded axis is installed in the gear rack, which, compressing the spring, has the possibility of axial movement in the hole of the gear rack.

A fork with a driven pulley is installed at the end of the axle. A handle with a toothed sector is installed on top of the guide housing, which in the closed state fixes the toothed rail in the axial direction. The guide body is mounted on a plate, which, in turn, is mounted on the axis of the drive pulley.

To install and tighten the linker tape, it is necessary to remove the fixing from the toothed rail with the specified handle, after which it can move freely along the axis of the opening of the guide housing. Install the linker tape on the drive pulley, pull out the gear by hand

From the rail with the driven pulley, thereby selecting the gap between the pulley and the linker belt.

By turning the handle, lock the toothed rail, which, when locked, moves forward and compresses the spring installed on the axis, thus ensuring the tension of the linker tape. Install the link belt on the drive pulley with the movable body so that the spacers installed on this link belt mesh with the spacers on the second link belt.

The disadvantages of the closest analogue are the following: 1. Over time, the spring loses its rigidity, due to which the tension force changes. 2. Fixation of the departure of the driven pulley on the toothed rail is stepped, therefore it is impossible to achieve constancy of the tension force of linker tapes of different sizes, in addition, when re-installing the same linker tape, it is possible to fix it on different teeth of the rail with different degrees of spring compression, which will also lead to changes in the tension of the linker tape. 3. Complexity of the linker tape replacement process. All manipulations when tensioning the linker tape are performed manually, the process requires the support of the linker tape until it is fully tensioned, as well as the extension of the toothed rails and their fixation with the help of a handle.

The technical result achieved in the useful model is: 1. Constant and adjustable tensioning effort of the linker tape, which eliminates the risk of human error. 2. Simplified process of replacing the linker tape.

C. Ease of manufacturing due to the elimination of the most time-consuming parts of the unit (rail, toothed sector, handle block), as well as reducing the total number of parts.

The claimed technical result is achieved by the fact that in the linker mechanism of the device for making sausages or anchovies, containing the first and second guide bodies, the first and second linker tapes with separators attached to them, the first and second pulleys, made with the possibility of rotation on the corresponding first and second vertical axes, the third and fourth pulleys, made with the possibility of rotation on the corresponding third and fourth vertical axes for bringing the first and second linker tapes, respectively, into counter-parallel movement, the first and second tensioning devices of the corresponding linker tapes and the protective casing of the linker mechanism, according to the useful model, the first and second devices for tensioning the corresponding link tape are made in the form of the first and second linear drives, respectively, on which the corresponding first and second pulleys are fixed.

Each of the first and second guide bodies can be made in the form of upper and lower plates connected by supports, in which the corresponding first and second linear actuators are installed.

Each linker belt can be made in the form of a cable, or a chain, or a smooth belt, or, what is better, a toothed belt.

It is particularly preferable that the first and second linear actuators are made in the form of first and second pneumatic cylinders, respectively, each containing a rod and a rodless cavity.

The linker mechanism is preferably equipped with a sensor for the position of the protective casing of the linker mechanism, made with the possibility of controlling the air supply to the rod cavity of the pneumatic cylinders of the tensioning mechanism of the first and second linker tape.

The declared useful model is explained by drawings:

Fig. 2 - linker mechanism in the process of tensioning one of the linker tapes;

Fig. 3 - a schematic representation explaining the principle of operation of a private example of the implementation of a linear drive in the form of a pneumatic cylinder;

Fig. 4 - linker mechanism in section A-A.

The claimed linker mechanism includes first and second linker tapes with spacers attached to them. The linker belt can be made in the form of a cable, or a chain, or a smooth belt, in this implementation example, the linker belt is made in the form of the first 1 and the second 2 closed toothed belts with separators 3 attached to them. The first toothed belt 1 goes around the first guide housing 4 and the first pulley 5, made by the driven with the possibility of rotation on the corresponding first vertical axis b and the third pulley 7, made by the driver with the possibility of rotation on the corresponding third vertical axis 8 to drive the first toothed belt 1. The second toothed belt 2 surrounds the second guide housing 9 and the second pulley 10, made by the driven with the possibility of rotation on the corresponding second vertical axis 11, and the fourth pulley 12, made by the driver with the possibility of rotation on the corresponding fourth vertical axis 13 to drive the second toothed belt 2 in the opposite -parallel movement relative to the first toothed belt 1.

The first and second tension devices of the corresponding toothed belt are made in the form of the first and second linear drives, respectively, made in this example in the form of the first

From 14 and the second 15 pneumatic cylinders, on the rods of which the first 16 and second 17 forks are fixed, in which the first 6 and second 11 axes of the first 5 and second 10 pulleys are installed, respectively.

The first and second guide housings in this example are made in the form of upper 18 and 19 and lower 20 and 21 plates, connected by supports 22, in which the corresponding first 14 and second 15 pneumatic cylinders are installed. Plates 18 and 20 and 19 and 21 are made to ensure the possibility of movement of said forks 16 and 17 between them.

The principle of operation of the linker tape tensioning device.

The tension of each linker belt, in this example the first toothed belt 1 and the second toothed belt 2, is carried out by the corresponding pneumatic cylinders 14 and 15.

The principle of operation is explained on the example of tensioning the first toothed belt 1 using the first pneumatic cylinder 14.

The principle of tensioning the toothed belt (according to Fig. 1-4) is that the tension of the toothed belt occurs due to the difference in pressure in the rodless and rod cavities of the pneumatic cylinders (P and P2, respectively).

To ensure the necessary tension force of the first toothed belt 1, air with a specified pressure P1 is constantly supplied to the rodless cavity 23 of the pneumatic cylinder 14. Air is not supplied to the rod cavity 24 of the pneumatic cylinder 14. Due to the difference in pressure on the piston 26 on the side of the rod cavity 24 and on the side of the rodless cavity 23, the rod 25 pulls the first toothed belt 1 (Fig. 4).

The protective casing (not shown in the figures) of the linker mechanism is equipped with a position sensor (not shown in the figures), which through the control system (not shown in the figures) controls at least one distributor (not shown in the figures), which is responsible for the supply of air with pressure P2 into the rod cavity 24 of the pneumatic cylinder 14.

When opening the protective casing of the linker mechanism, the specified distributor under the influence of the specified position sensor supplies air with a pressure of Рg equal to the air pressure P1 in the rodless cavity 23 into the rod cavity 24 of the pneumatic cylinder 14. The pressure from the two sides of the piston 26 is approximately equalized, the pressure of the rod 25 on the first toothed belt 1 and the tension of the first toothed belt 1 weakens, which allows the replacement of the first toothed belt 1.

To do this, it is enough to press the rod 25 of the cylinder 14 through the driven pulley 5, which is installed on the fork 16, with a small effort, and remove the first toothed belt 1. After removing the first toothed belt 1, the rod 25 of the pneumatic cylinder 14 together with the driven pulley 5,

installed on fork 16, will extend to the maximum distance. This happens due to the peculiarity of rod pneumatic cylinders, in which, in case of equality of pressures in the rod and rodless cavities of the pneumatic cylinder, the force acting on the piston 26 of the pneumatic cylinder 14 on the side of the rodless cavity 23 is slightly higher than the opposing force created on the side of the rod cavity 24 of the pneumatic cylinder 14.

To put on the first toothed belt 1, made closed, you should first put on the first toothed belt 1 on the driven pulley 5 installed on the fork 16 of the rod 25 of the pneumatic cylinder 14.

Next, applying a slight force, pull the opposite part of the first toothed belt 1, thereby pulling in the rod 25 with the driven pulley 5 installed on it, until it becomes possible to put this part of the first toothed belt 1 on the driven pulley 7.

Since a small amount of tension is maintained during timing belt replacement, the timing belt does not need to be maintained until it is fully tensioned.

When closing the protective casing of the linker mechanism according to the signal of the position sensor, the distributor releases excess pressure P2 from the rod cavity 24 of the pneumatic cylinder 14.

Due to the difference in pressure on the piston 26 on the side of the rod cavity 24 and on the side of the rodless cavity 23, the rod 25 pulls the first toothed belt 1.

The tension of the second toothed belt 2 occurs similarly with the help of the second pneumatic cylinder 15. The first 1 and the second 2 toothed belts are installed so that the dividers C are opposite each other.

The technical result achieved in the claimed utility model: 1. Constant and adjustable tensioning effort of the linker tapes, which eliminates the risk of human error. 2. Simplified process of replacing the linker tape. The tension is automatic when the skin is closed, and thanks to the pre-tensioning force during the installation of the belt, it does not need to be maintained until it is fully tensioned.

Z. Ease of manufacture. Thanks to the use of a pneumatic cylinder, it was possible to get rid of the most time-consuming parts of the unit (rail, toothed sector, handle block), and also to reduce the total number of parts. The cost of the node has been significantly reduced.
