[Problem that the invention attempts to solve]

However, with the drive device of the conventional food forming/cutting machine mentioned above, it is difficult to raise and lower the forming/cutting machine main body in accordance with the descending speed of the food material, and it is difficult to move the main body of the forming/cutting machine up and down in accordance with the descending speed of the food material. When forming and cutting a round bar-shaped food material surrounding the outer periphery of the core material, if the squeeze piece of the food forming/cutting machine main body is closed at a constant speed, the outer skin material cannot be sufficiently stretched and formed, resulting in the cut product being cut. The preferred pattern for closing the squeeze pieces differs depending on the material of the food material, such as the upper and lower end surfaces of the food material are not joined by the outer skin material, and this poses a problem in that it is difficult to neatly shape and cut multiple types of food materials made of different materials. This invention solves the above-mentioned problems and is capable of reliably forming and cutting food materials that descend at a predetermined speed, and is also capable of easily handling the forming and cutting of multiple types of food materials with different materials. The purpose is to provide a driving device for a machine.

By rotating the main shaft with an electric motor, the elevating cam is driven and the elevating platform is lowered, and the food forming/cutting machine body can be lowered in accordance with the speed of the rod-shaped food material that is descending at a predetermined speed. As the lifting platform descends, the opening/closing shaft supported by the opening/closing template moves, and the operating rod moves via the power transmission mechanism.
By closing the squeeze piece of the shaping/cutting machine main body, a rod-shaped food material can be shaped and cut, and then the shaping/cutting machine main body can be returned to the upward position and the squeeze piece can be opened. Therefore, depending on the shape of the elevating cam and the opening/closing template, it is possible to perform the closing operation of the drawing piece that is suitable for the material of the food material, especially the material of the outer skin material, while lowering the main body of the forming/cutting machine. , can cleanly shape and cut food materials.
Moreover, since a template is used to open and close the aperture piece,
Compared to using a cam, the complicated opening operation can be performed by a squeeze piece, and the opening/closing template is removably fixed to the device frame, so multiple types of opening/closing templates can be used depending on the material of the food material, etc. By preparing these in advance and replacing them depending on the material of the food material, etc., the pattern in which the squeeze pieces close can be easily changed depending on the food material to be used.

These diaphragm pieces 40 are supported by the frame 38 along each side around the opening 38b so that one oblique side can move back and forth in a straight line, and the other oblique side slides on the long bottom side of the adjacent diaphragm piece 40. The fact that a regular hexagonal hole that can be opened and closed is formed in the center side of the aperture piece 40, which is movably supported and surrounded by the long base of the aperture piece 40, is similar to that shown in the above-mentioned Japanese Utility Model Publication No. 85178/1983.

b are formed respectively. In addition, in FIG. 1, 42 is a round bar-shaped food material that is double extruded from a nozzle of an extruder (not shown), and the food material 4
2 is a food material 42 consisting of a core material such as bean paste and a skin material 42b surrounding the outer periphery of the core material.
are arranged to descend so that their axes coincide with the center of the hole formed by the drawing piece 40, and a conveyor for carrying out (not shown) is disposed below the forming/cutting machine body 30. . Next, the operation of the embodiment configured as above will be explained. A round bar-shaped food material 42 extruded from a nozzle of an extruder (not shown) descends at a predetermined speed, and the lower end of the food material 42 reaches the forming/cutting machine main body 30.
The aperture piece 40 reaches the lower end thereof in a fully opened state. At this time, the main shaft 8 is rotated by the drive of the electric motor 6 via the reducer 5, pulley 9a, timing belt 11, and pulley 9b, and the lifting cam 10 is also rotating. The cam follower 14 engaged with the cam groove 10a descends according to the shape of the cam groove 10a, and the lifting platform 11 starts to descend from its upper limit against the spring force of the spring 12 via the lifting arm 13. The shaping/cutting machine main body 30 descends together with the lifting table 11 at the same speed as the food material 40. As the lifting platform 11 descends, the opening/closing shaft 15 also descends, and the roller 2 connected to it via the joint 18
A spring 16 is attached to the guide surface 21a of the opening/closing template 21 which is fixed to the device frame 1 via the bracket 22.
Since the roller 20 is pressed by the spring force of
The opening/closing shaft 15 moves in the left-right direction in the figure via the joint 18. This movement is magnified by the rotation of the link lever 25 and transmitted to the interlocking shaft 24, the interlocking shaft 24 moves in the opposite direction to the opening/closing shaft 15, and the intermediate gear 33 rotates via the drive side rack 32. , the driven side rack 34 moves downward in FIG. 2, and the operating rod 31 also moves downward in FIG. 2 via the connecting shaft 35. Therefore, as the squeeze piece 40 fixed to the operating rod 31 moves, the other squeeze pieces 40 also move, and the hole formed by these pieces is gradually made smaller from fully opened, thereby squeezing the food material 42. Recessed portion 40b on the lower surface of piece 40
When the shaping/cutting machine main body 30 reaches its lower limit, the hole formed by the squeezing piece 40 is completely closed, the food material 42 is cut, and the shaped and cut food material is transported out. It falls onto a conveyor and is carried out by this conveyor. Further, the upper part of the cut portion of the food material 42 is located in the recess 4 on the upper surface of the squeeze piece 40.
The lower part is formed by 0a. After the forming/cutting machine main body 30 reaches its lower limit and the hole is completely closed, the cam groove 1 of the lifting cam 10 and the opening/closing template 21 is opened.
0a and the shape of the guide surface 21b, the aperture piece 4
0 moves in the opening direction, and the forming/cutting machine main body 30 rises via the lifting table 11, and returns to the state before operation via the power transmission mechanism 41, but the round bar-shaped food material 42 is moved at a predetermined speed. Since the lower end of the food material 42 is at the upper limit of the shaping/cutting machine main body 30, the squeezing piece 40 returns to the fully open state, and the above-described operations are repeated. In this embodiment, the roller 20 pressed against the guide surface 21a of the opening/closing template 21 is
1, the throttle piece 40 narrows the hole to some extent by passing through the part shown by the solid line in FIG. Fully closed, lifting platform 1
1, the roller 20 passes through the part shown by the broken line in FIG. 1 and rapidly opens to its full opening, and the lifting platform 11 reaches its upper limit, resulting in an almost elliptical movement that repeats the above-mentioned operation. , aperture piece 40
performs the motion shown in Figure 3a. For this reason, food material 4
Even though the outer skin material 42b of No. 2 is made of a highly elastic material, after it is gathered together, it is slightly loosened and gathered again, and as shown in FIG. 3b, the core material 42a
In addition to adhering to the food material after forming and cutting,
Even at the lower end, the food material whose upper and lower end surfaces are joined can be molded and cut without reducing the thickness of the outer skin material 42b too much. On the other hand, if the opening of the throttle piece 40 is closed quantitatively as shown in FIG. 4a as the lifting platform descends, as shown in FIG. 4b,
The outer skin material 42b made of a material with high elasticity is cut without being able to gather all the parts, and the outer skin material 42b is not joined at the upper and lower end surfaces of the food material after forming and cutting. Then, by using other opening/closing templates with different shapes of guide surfaces prepared in advance depending on the material of the food material, especially the material of the outer skin, food materials of different materials are joined to the desired shape at the top and bottom end surfaces. Can be cut into shapes. To replace the opening/closing template, remove the thumb screw 23, remove the opening/closing template 21 from the bracket 22, and then tighten the opening/closing template with a different guide surface shape to the bracket 22 with the thumb screw 23. So it's easy to do. The cam groove 10a of the lifting cam 10 is formed in such a shape that the lifting table 11 is lowered at the same speed as the food material 42 and raised rapidly. In this embodiment, when cleaning the forming/cutting machine main body 30, the case 2 of the protrusion 38a of the frame 38 is fixed by the knob screw 36 while the electric motor 6 is stopped.
7 and pull the molding machine main body 30 to the left in FIG.
5 side and the frame 38 is attached to the case 27 of the support part 26.
Remove from. Alternatively, remove the knob screw 36, remove the cover 29, and remove the case 27 of the support part 26.
A part of the upper surface is opened, and from this opening, the pressure of the operating rod 31 against the connecting shaft 35 by the knob screw 44 is loosened, and the frame 3 is further removed by the knob screw 39.
By loosening the pressure of the protrusion 38a of 8 on the case 27 and pulling the forming/cutting machine main body 30 to the left side in FIG.
At the same time, the operating rod 31 is pulled out from the connecting shaft 35. Therefore, in any of the above states, carry the forming/cutting machine main body 30 to an appropriate location and remove the drawing piece 4.
0 from the frame body 38 and wash them, and also clean the conveyor for carrying out which was located below the forming/cutting machine main body 30 at the time of installation. Thereafter, the drawing piece 40 is assembled to the frame body 38, and the frame body 38 is fixed to the case 27 in the reverse order of the above-described removal operation, and the forming/cutting machine main body 30 is returned to the state before being removed. The shaping/cutting machine main body 30 can be replaced with one having various polygonal openings, for example, a regular octagonal opening, by the same operation as in cleaning. In addition, in this invention, the mechanism for removably fixing the opening/closing template to the equipment frame can be changed as appropriate, such as making the opening/closing template removable from the equipment frame together with the bracket, and the opening/closing shaft can be replaced with a stylus instead of a roller. This may be used and pressed against the guide surface of the opening/closing template. Furthermore, in this invention, the power transmission mechanism can be modified as appropriate as long as it is connected to the opening/closing shaft and the member at the output end is connected to the operating rod, but the structure of the embodiment can be used to reduce the size.

[Effect of the idea]

As explained above, according to this invention, by rotating the main shaft with an electric motor, the elevating cam is driven and the elevating table is lowered, and the food material cutting machine body is lowered at a predetermined speed. It can be lowered according to the speed, and as the lifting platform descends, the opening/closing shaft is guided by the opening/closing template and moves the operating rod via the power transmission mechanism, thereby reducing the aperture of the forming/cutting machine body. By closing the pieces, the rod-shaped food material can be shaped and cut, and then the shaping/cutting machine body can be returned to the upward position and the squeeze pieces can be opened. Therefore, in this invention, the shapes of the lifting cam and the opening/closing template allow the closing operation of the drawing piece according to the material of the food material to be performed while lowering the main body of the forming/cutting machine. The molding can be cut cleanly, and since a template is used to open and close the drawing piece, any complex closing action can be performed on the drawing piece, and the opening/closing template can be removably fixed to the device frame. By doing so, it is possible to easily change the opening/closing template according to the material of the food material, etc., and it is possible to provide a drive device for a food forming/cutting machine suitable for forming and cutting multiple types of food materials of different materials. There is an effect.
