Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a drive device for a food forming/cutting machine such as a filling machine.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Application Publication No. 60-85178, for example, an aperture piece guide with a regular hexagonal opening was used as the frame of the main body of a food molding machine, and six trapezoidal shapes were installed in the opening of the guide. The diaphragm pieces are each supported so as to be linearly reciprocating along each side around the opening, and are also supported so as to be slidable relative to each other, and a hole similar in shape to the opening of the diaphragm piece guide is formed that can be opened and closed. When the hole is opened, a rod-shaped food material that descends at a predetermined speed is placed in the hole, and the drive device slides the squeeze pieces to close the hole, thereby forming the food material into a nearly spherical shape with each squeeze piece. Food molding and cutting machines that cut food products using In addition, the drive device of this food molding and cutting machine transmits an electric motor that rotates forward and backward to the aperture piece through a motion conversion mechanism that converts rotation into linear reciprocating motion, and opens and closes the aperture piece in the horizontal direction. Ta.

[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 cutting a round bar-shaped food material that surrounds the outer periphery of the core material, if the squeeze piece of the food forming cutting machine body is closed at a constant speed, the outer skin material cannot be stretched sufficiently and the cutting process will be interrupted. The problem is that the preferred pattern for closing the squeeze piece differs depending on the material of the food material, such as the upper and lower end surfaces of the product are not joined by the outer skin material, and it is difficult to neatly shape and cut multiple types of food materials made of different materials. It was hot. This invention solves the above-mentioned problems and can reliably shape and cut food materials that descend at a predetermined speed, and also allows the device to be large-sized to mold and cut multiple types of food materials made of different materials. The purpose of the present invention is to provide a drive device for a food forming/cutting machine that can be easily handled without any problems.

[Means to solve the problem]

The drive device of the food forming and cutting machine according to this invention is as follows:
A main shaft driven by an electric motor is vertically supported on the device frame, a lifting cam is provided on the main shaft for raising and lowering a lifting platform that is movably supported on the device frame, and several throttle pieces are attached to the frame. The frame body of the main body of the food forming and cutting machine, which is supported in an openable and closable manner, is mounted on the lifting platform, and a camshaft that is interlocked with the main shaft or rotated by the electric motor is pivotally supported on the lifting platform, and the camshaft is attached to and detached from the camshaft. an opening/closing cam plate is movably fixed, an opening/closing shaft supported by the cam plate is movably supported on a lifting platform, and an operating rod for opening/closing the throttle piece is connected to the opening/closing shaft via a power transmission mechanism; The rotation of the main shaft causes the throttle pieces to open and close following the shape of the cam plate.

[Effect]

The drive device for the food forming and cutting machine based on this invention is
By rotating the main shaft with an electric motor, the elevating cam and the opening/closing cam plate are driven in synchronization, and the elevating cam lowers the elevating platform, which lowers the main body of the food forming and cutting machine at a predetermined speed. While lowering the food material according to the speed of the food material, the opening/closing shaft is moved by the opening/closing cam plate, and the operating rod is moved via the power transmission mechanism to close the aperture piece of the forming/cutting machine main body. As a result, a rod-shaped food material can be shaped and cut, and then the shaping and cutting machine main body can be returned to the upward position and opened. Therefore, depending on the shape of the elevating cam and the opening/closing cam plate, it is possible to perform a closing operation of the drawing piece adapted to the material of the food material, especially the material of the outer skin material, while lowering the forming/cutting machine main body. Can cleanly shape and cut food materials. Furthermore, the opening/closing cam plate that opens and closes the throttle piece is removably fixed to a camshaft supported on the lifting platform.
Unlike if the opening/closing cam plate was attached removably directly to the main shaft, it would be troublesome to replace the opening/closing cam plate because it would get in the way of other parts.In contrast, the camshaft is placed in a position where the opening/closing cam plate can be easily attached/detached. In addition, this cam plate can be installed in a part that does not make the device large. Therefore, multiple types of opening/closing cam plates are prepared in advance according to the material of the food material, and these can be installed in a part that does not make the device large. By changing the material, etc., the pattern in which the squeeze pieces close can be easily changed depending on the food material used.

A round bar-shaped food material 45 extruded from a nozzle of an extruder (not shown) descends at a predetermined speed, and the lower end of the food material 45 is attached to the forming/cutting machine main body 34.
The aperture piece 44 reaches the lower end thereof in a fully open state. At this time, the main shaft 8 is rotated by the drive of the electric motor 6 via the reducer 5, pulley 9, timing belt 11, and pulley 10, and the elevating cam 14 is also rotating, so the cam groove 14a of the elevating cam 14 is rotated.

also moves downward in Figure 2. For this reason, the operating rod 35
By moving the throttle piece 44 fixed to the holder, the other throttle pieces 44 also move, and the hole formed by these pieces is gradually made smaller from fully opened, so that the food material 4
5 is squeezed and shaped by the concave portion 44b on the lower surface of the drawing piece 44, and when the shaping/cutting machine main body 34 reaches the lower limit,
The hole formed by the throttle piece 44 is completely closed,
The food material 45 is cut, and the shaped and cut food material falls onto a conveyor for carrying out and is carried out by this conveyor. Further, the lower part of the upper part of the cut portion of the food material 45 is formed by the recess 44a on the upper surface of the squeeze piece 44. After the forming/cutting machine main body 34 reaches its lower limit and the hole is completely closed, the throttle piece 44 moves in the opening direction depending on the shape of the cam groove 14a and the cam surface 24a of the elevating cam 14 and the opening/closing cam plate 24. The forming/cutting machine main body 34 rises via the lifting platform 15 and returns to the state before operation via the power transmission mechanism 48, but the round bar-shaped food material 45 descends at a predetermined speed. Therefore, the aperture piece 44 is returned to the fully open state before the forming/cutting machine main body 34 reaches its upper limit, and the above-described operations are repeated. In this embodiment, one of the opening/closing cam plates 24 is
By synchronizing the rotation and one round trip of the lifting table 15, the food forming and cutting machine can be operated at high speed. In addition, the link lever 29 controls the linear reciprocating movement of the opening/closing shaft 25 due to the rotation of the opening/closing cam plate 24.
By transmitting a large amount of movement to the interlocking shaft 28 by the rotation of the cam plate 24, the opening/closing cam plate 24 can be made smaller without the shape of the opening/closing cam plate 24 directly expressing the cutting pattern by the aperture piece 44. This leads to the miniaturization of the drive device. moreover,
Due to the shape of the cam surface 24a of the opening/closing cam plate 24,
As shown in FIG. 3a, when the lifting platform 15 is lowered, the closing operation of the throttle piece 44 temporarily stops or opens slightly, and then the hole is narrowed again and is fully closed at the lowering limit of the lifting platform 15. When the lifting table 15 is reversed in its upward movement, it rapidly opens to its full opening, and the throttle piece 44 moves as shown in FIG. 3a so that the lifting table 15 reaches its upper limit. Therefore, the outer skin material 45b of the food material 45 is
Even if the material is highly elastic, after it is gathered, it is slightly loosened and gathered again, so that it adheres tightly to the core material 45a as shown in FIG. Outer skin material 45
The food material can be molded and cut into a desired shape in which the upper and lower end surfaces are joined without making the thickness of b very thin. On the other hand, if the aperture piece closes the hole quantitatively as shown in Fig. 4a as the lifting platform descends, as shown in Fig. 4b, the The outer skin material 45b of the material is cut without being gathered together, and the outer skin material 45b is not joined at the upper and lower end surfaces of the food material after forming and cutting. By using opening/closing cam plates prepared in advance with different cam surfaces depending on the material of the food material, especially the material of the outer skin, food materials made of different materials can be shaped into the desired shape with the upper and lower end surfaces joined. Can be shaped and cut. Opening/closing cam plate 2
To replace item 4, remove the thumbscrew 47 and remove the opening/closing cam plate 24 from the tip surface of the camshaft 22, then replace the opening/closing cam plate with a different cam surface with the thumbscrew 47 on the camshaft 22.
In this case, the opening/closing cam plate is small, and the camshaft 22 is rotated from the main shaft 8 via the transmission shaft 18, etc., so it is easy to replace the part of the device frame 1. The opening/closing cam plate 24 can be arranged, and these can be easily replaced. The cam groove 14a of the lifting cam 14 may be formed in such a shape that the lifting table 15 descends at the same speed as the food material 45 and rises rapidly. In this embodiment, when cleaning the forming/cutting machine main body 34, the case 31 of the protrusion 42a of the frame 42 is fixed by the knob screw 43 while the electric motor 6 is stopped.
By loosening the pressure on the molding machine body 34 and pulling the molding machine body 34 to the left side in FIG.
Remove the frame 42 from the case 31 of the support part 30, leaving it on the side. Alternatively, remove the knob screw 32,
Remove the cover 33, open a part of the upper surface of the case 31 of the support part 30, loosen the pressure of the operating rod 35 against the connecting shaft 39 by the knob screw 40 through this opening, and then remove the frame body by the knob screw 43. 42
Loosen the pressing of the protrusion 42a against the case 31,
By pulling the forming/cutting machine main body 34 to the left in FIG. Therefore, in any of the above states, select a suitable location for the forming/cutting machine main body 34, remove the drawing pieces 44 from the frame 42, wash them, and remove the lower part of the forming/cutting machine main body 34 when installed. Clean the unloading conveyor located at Thereafter, the aperture piece 44 is assembled to the frame body 42, and the frame body 42 is fixed to the case 31 in the reverse order of the above-described removal operation, and the forming/cutting machine body 34 is returned to the state before being removed. The shaping/cutting machine main body 34 can be replaced with one having various polygonal openings, for example, a regular octagonal opening, by the same operation as in cleaning. In this invention, the camshaft may be driven by an electric motor that rotates the main shaft via a rotational force transmission mechanism incorporating a suitable flexible member. Further, 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 and the operating rod, but the structure of the embodiment can be made smaller.

[Effect of the idea]

As explained above, according to this invention, by rotating the main shaft with an electric motor, the elevating cam and the opening/closing cam plate are synchronously driven, and the elevating platform is lowered by the elevating cam. While the main body of the food forming/cutting machine is lowered in accordance with the speed of the rod-shaped food material that is descending at a predetermined speed, the opening/closing shaft is moved back and forth by the opening/closing cam plate provided on the lifting platform, and the operating lever is operated via the power transmission mechanism. By moving 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 moved back up and opened. Therefore, in this invention, the shape of the lifting cam and the opening/closing cam plate allows the closing operation of the squeeze piece according to the material of the food material to be performed while lowering the forming/cutting machine body.
Food materials can be formed and cut cleanly, and the opening/closing cam plate is removably fixed to the camshaft provided on the lifting platform, so although it is small, it can be easily used as the opening/closing cam plate according to the material of the food material. This has the effect of providing a drive device for a food molding and cutting machine suitable for molding and cutting a plurality of types of food materials of different materials.
