Description

[Detailed description of the invention] (Objective of the invention, field of industrial application) The present invention is utilized in the field of tofu production.

The present invention relates to a tofu cutting device.

(Prior art and its problems) In the tofu manufacturing process, the tofu is compressed and packed in JQJ boxes and then cut into the final product.If you are not used to this cutting process, you may end up cutting the tofu into deformed cubes, which may result in the product being cut into deformed cubes. loses its value.

For this reason! Although it has been desired to mechanize the cutting process, it has not yet been fully realized and it has been considered difficult to mechanize this cutting process.

In the case of firm tofu, the bottom of the mold box will be the surface of the tofu. Since the surface of tofu is hard, when cutting from the top of the mold box, that is, from the back side of the tofu, the surface must be cut completely to the surface, otherwise the surface will collapse and lose its commercial value.

Therefore, when cutting σ rot, it is necessary to cut from the surface.

(Objective of the present invention) The present invention is.

(a) Mechanizing the tofu cutting process, (b) Preventing the surface of tofu from molding by cutting from the surface, etc. The purpose is to provide a disconnection device.

(Structure of the present invention) The present invention includes a reversing device l for reversing a mold box, and an η! σ from the box
This tofu cutting device is equipped with a switching device 2 for taking out the curd, and a cutting device 3 for cutting the tofu taken out from the mold box.

Then, the mold box placed on the reversing device 1 is reversed, put into the exchange device 2 for taking out the σ-fu from the mold box, and the tofu is taken out.The tofu is cut and sent to the water tank. Repeat this operation to sequentially cut the tofu.

(Example) The present invention will be described in more detail based on an example shown in the drawings.

The other end of the swinging arm 314 is rotatably attached to a rod head of a cylinder 310 which is rotatably attached to the pillar 311 (the base portion) with a pin.

A cutter 31 is attached to the rod head 312 of the cutting cylinder 311 and is capable of cutting off rot in the mold box 101 in one go.

Ru.

(1) After placing the mold box 101t-4JL on the reversing arm 10, the clamping cylinder 150 is operated to rotate the clamping tool 15 inward, thereby clamping and fixing the mold box 101.

(2) Remove the bottom plate 102, open the cloth 11], and open the mold box +0
1 and place the bottom plate 102 directly on top of the tofu.

(3) Activate the cylinders 110 and 130, rotate the cloth stop lever 13 in the direction F, and press the mold box 101 from above while holding the cloth.

(4) The above 41 width stopper lever! At the same time, the bottom plate holder 12 also rotates upward, and the bottom plate 102 is pressed and fixed from above.

(5) The roller stand 22 and the 4110 receiving frame 24 are stopped and waiting at approximately the same position as the -E edge of the fixed base frame 21.

(6) Operate the cylinder 230 and press the press roller 2.
31 to open the cloth stopper lever 23 outward.

(7) Actuate the actuator M, rotate the reversing arm lO to the right in FIG. 1, and place the mold box 101 a on the exchange frame 21.

(8) When the bottom plate 102 slides down a little along with the tofu and rests on the -L of the roller stand 22, the cylinders 110 and 130 operate to release the temporary fixation of the cloth. As a result, the dish towel hangs outside the dish towel receiving frame 24.

(9) Operate the cylinder 230 and push up the roller 23
1 is lowered to close the cloth stopper lever 23, and the cloth is held between the claw 232 at the tip and the cloth receiving frame 24.

(10) When the cylinders 220 and 240 are activated, the roller stand 22 descends with the tofu placed on it, and the dish towel receiving frame 24 and dish towel stopper lever 23 descend with the dish towel sandwiched therebetween. As a result, the cloth is peeled off from the tofu (11), the roller table 22 is lowered to the edge of the exchange frame 21, and the tofu is removed from the mold box 1.
Move from 01 to replacement frame 21.

(12) Activate actuator M 1 reversing arm 10
is reversed and returns to its original state. The clamping tool 15 is released and the mold box 101 is replaced.

(13) Activate the cylinder 230, open the second lever 23 of the cloth 11 to the outside, and release the grip of the cloth 1.
Remove 1.

(14) Operate the cylinder 310 and cutter 31
is set right above the exchange frame 21, the cylinder 311 is operated, and the cutter 31 cuts the tofu in the exchange frame 21.

(16) Rotate the cutter 31 upward and return it to its original position.

(17) Operate the cylinder 220 to raise the roller stand 22. When the cylinder 220 is raised to the position indicated by the imaginary line in Figure 0, the stopper rod 253 is stopped by the stopper 198. As a result, the roller stand 22 is tilted about the shaft 228, and the tofu is dropped into the water tank together with the bottom plate 2.

(18) The roller stand 22 is lowered by the cylinder 220, and the cloth receiving frame 24 and the cloth holding lever 23 are moved by the cylinder 220.
40 and wait at the position shown in (5).

In this embodiment, the operations described in (h) are repeated, and the work from reversing the mold box to cutting the burr can be efficiently performed.

Note that the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims.

(Effects of the Invention) The present invention includes a reversing device 1 for reversing a mold box, a switching device 2 for taking out tofu from the mold box, and a cutting device 3 for cutting the tofu taken out from the mold box.

(a) The labor-intensive process of cutting tofu can be mechanized.

(b) Since tofu is cut from the surface, it is possible to provide a tofu cutting device that can prevent molding of the surface of tofu.
