Description

The claimed utility model relates to equipment for the production of sausages, mainly intended for use in an automatic line for the production of sausages or small 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 the manufacture of sausages or small sausages are widely known, for example from [1], or from [2], or from [3]. Known linker mechanisms include first and second linker belts with spacers attached thereto, driven by pulleys rotatable on respective vertical axes.

Linker mechanisms are equipped with drives, and can also be equipped with various additional elements, depending on the technical problem being solved.

However, the known sources of information do not disclose in any way the mechanism of tension of the linker tapes.

The closest technical solution is a linker mechanism for the line for the production of sausages or small sausages from VEMAG (DE) [4].

The known linker mechanism includes a protective sheathing of the linker mechanism, the first and second housing guides, the first and second linker belts with spacers attached to them, the first and second pulleys capable of rotation on the respective first and second vertical axes, the third and fourth pulleys rotatable on respective third and fourth vertical axes to drive the respective first and second linker belts in counter-parallel movement, and first and second tensioning devices for the respective linker belts. Each linker belt tensioner is a circular toothed rack mounted in a bore of the guide body. A spring-loaded axle is installed in the toothed rack, which, by compressing the spring, has the possibility of axial movement in the hole of the toothed 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 body, which in the closed state fixes the toothed rack 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 tension the linker tape, it is necessary to remove the fixation from the toothed rack with the indicated handle, after which it has the ability to move freely along the axis of the hole of the guide body. Install the linker belt on the drive pulley, pull out the toothed rack with the driven pulley by hand, thereby selecting the gap between the pulley and the linker belt. By turning the handle, fix the toothed rack, which, when locked, moving forward, compresses the spring mounted on the axle, thereby providing tension on the linker tape. Place the linker belt on the movable body drive pulley so that the spacers installed on that linker belt engage with the spacers on the second linker belt.

The disadvantages of the known technical solution are as follows:

1) Over time, the spring loses its stiffness, which changes the tension force.

2) Fixation of the departure of the driven pulley along the toothed rack is stepped, therefore it is impossible to achieve a constant tension force of linker belts of different sizes, in addition, when reinstalling the same linker belt, fixation on different teeth of the rack with a different degree of spring compression is possible, which will also lead to a change in the tensile force of the linker tape.

3) The complexity of the process of replacing the linker tape. All manipulations when tensioning the linker tape are performed manually, the process requires maintaining the linker tape until it is fully tensioned, as well as extending the toothed racks and fixing them with a handle.

The technical results achieved in this utility model are

1) Constant and adjustable tension of the linker tape, which eliminates the risk of human error.

2) Simplified process of replacing the linker tape.

3) Ease of manufacture by eliminating the most labor-consuming parts of the assembly (rack, gear sector, handle block), as well as reducing the total number of parts.

The claimed technical results in the linker mechanism of the device for the production of sausages or small sausages, containing the first and second guides of the body, the first and second linker belts with spacers 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 the fourth pulleys, made with the possibility of rotation on the respective third and fourth vertical axes to drive the first and second linker belts, respectively, in counter-parallel movement, the first and second tensioning devices of the corresponding linker belts and the protective skin of the linker mechanism are achieved due to the fact that the first and the second tensioning device of the corresponding linker tape is made in the form of the first and second linear drives, respectively, on which the corresponding first and second pulleys are fixed.

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

Each linker belt can be in the form of either a cable or a chain, or a smooth belt, or, preferably, a toothed belt.

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

The linker mechanism is preferably equipped with a position sensor of the protective sheathing of the linker mechanism made with the possibility of controlling the air supply to the rod cavities of the pneumatic cylinders of the linker belt tensioning mechanism.

The claimed utility model is illustrated by the following non-limiting drawings:

The claimed linker mechanism contains the first and second linker tapes with spacers attached to them. The linker tape can be made in the form of either a cable or a chain or a smooth belt, in this embodiment, the linker belts are made in the form of the first 1 and second 2 closed toothed belts with spacers 3 attached to them. The first toothed belt 1 bends around the first guide body 4 and the first a pulley 5, made driven with the ability to rotate on the corresponding first vertical axis 6; and a third pulley 7, made by the leading, rotatable on the corresponding third vertical axis 8 to drive the first toothed belt 1 in motion. The second toothed belt 2 bends around the second guide body 9 and the second pulley 10, made slave with the possibility of rotation on the corresponding second vertical axis 11, and the fourth pulley 12, made of the leader, rotatable on the corresponding fourth vertical axis 13 to drive the second toothed belt 2 in the opposite direction. -parallel movement relative to the first toothed belt 1.

The first and second tensioning device of the corresponding toothed belt is made in the form of the first and second linear actuator, respectively, made in this example in the form of the first 14 and second 15 pneumatic cylinders, on the rods of which the first 16 and second 17 forks are fixed, in which the first 6 and the second 11 are installed the axes of the first 5 and second 10 driven pulleys, respectively.

The first 4 and second 9 guides of the housing in this example are made in the form of the corresponding 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 enable the movement of said forks 16 and 17 of the respective pneumatic cylinders 14 and 15 between them.

The principle of operation of the linker tape tensioner:

Each linker belt, in this example the first toothed belt 1 and the second toothed belt 2, is tensioned by the respective pneumatic cylinders 14 and 15.

Let us consider the principle of operation using the example of tensioning the first toothed belt 1 using the first pneumatic cylinder 14.

The principle of tensioning the toothed belt (in accordance with Fig. 1-4), is that the tension of the toothed belt occurs due to the pressure difference in the rodless and rodless cavities of the pneumatic cylinders (P1 and P2, respectively).

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

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

When the protective casing of the linker mechanism is opened, the specified distributor, under the influence of the specified position sensor, supplies air to the rod cavity 24 of the pneumatic cylinder 14 with a pressure P2 equal to the air pressure P1 in the rodless cavity 23. The pressure on both 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 is released, allowing the first toothed belt 1 to be replaced.

To do this, it is enough to slightly press on the rod 25 of the cylinder 14 through the driven pulley 5, which is installed on the fork 16 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 mounted on the fork 16 will move out to the maximum distance. This is due to the peculiarity of the rod pneumatic cylinders, in which, in the case of equal pressures in the rod and rodless cavities of the pneumatic cylinder, the force acting on the piston 26 of the pneumatic cylinder 14 from the side of the rodless cavity 23 is slightly higher than the counteracting force created from 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 mounted on the fork 16 of the rod 25 of the pneumatic cylinder 14. Then, applying a slight force, pull on the opposite part of the first toothed belt 1, thereby retracting 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 drive pulley 7.

Because Since a slight tension is retained during toothed belt replacement, the toothed belt does not need to be maintained until it is fully tensioned.

When the protective sheathing of the linker mechanism is closed, according to the signal from the position sensor, the distributor relieves excess pressure P2 from the rod end 24 of the pneumatic cylinder 14. Due to the pressure difference on the piston 26 from the side of the rod end 24 and from the side of the rodless end 23, the rod 25 pulls the first toothed belt 1.

The tension of the second toothed belt 2 is similar with the help of the second pneumatic cylinder 15. The first 1 and second 2 toothed belts are installed so that the spacers 3 are opposite each other.

The technical results achieved in the declared utility model:

1) Constant and adjustable tension force of the linker belts, which eliminates the risk of human error.

2) Simplified process of replacing the linker tape. Tensioning occurs automatically when the casing is closed, and due to the pre-tensioning force during installation, the belt does not need to be maintained until fully tensioned.

3) Ease of manufacture. Thanks to the use of a pneumatic cylinder, it was possible to get rid of the most labor-consuming parts of the assembly (rack, toothed sector, handle block), as well as to reduce the total number of parts. The unit cost has been significantly reduced.
