Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic tofu molding machine, and more particularly to an automatic tofu molding machine that makes tofu by molding while continuously conveying tofu raw materials.

[0002]

[Prior Art]

 Conventionally, as an apparatus for continuously producing tofu, for example, one shown in Japanese Patent Publication No. 53-39507 is known.

In the device disclosed in this publication, as shown in FIGS. 3 and 4, a wide endless lower filter cloth (b) is placed on a so-called caterpillar-shaped plate conveyor (b). A caterpillar-shaped pressure conveyor (f) is arranged so as to extend from above and face the plate conveyor (a) from above. In FIG. 3, the pressure conveyor is omitted for convenience.

Furthermore, in FIG. 3, a large number of undulating side plates (c) mounted by pivoting the respective base ends are attached to both side edges of the plate conveyor (a) which moves toward the left side (arrow X direction). It is set up. This undulating side plate (c) is erected via the left and right guide rails (d) and (d) fixed to the base, and the middle part of the lower filter cloth (b) that moves with the plate conveyor is U-shaped in cross section. The width of the tofu fabric is determined by changing the shape of the tofu. Further, an upper filter cloth (g) is arranged so as to cover the outer surface of the pressure conveyor (f).

Then, for example, a predetermined amount of tofu raw material is supplied from the charging port (e) to this trough portion and is conveyed in a predetermined direction while being pressed from above by a pressure conveyor (f) (not shown in FIG. 3, FIG. 4). Unnecessary water is removed by compressing with a suitable pressure at (See), and the tofu solidified into a rod shape is continuously fed out from one end (the left end in FIG. 3) on the lower filter cloth (b).

The thus-solidified rod-shaped tofu is cut at regular intervals with a cutter (not shown) to continuously make tofu of a required size.

[0007]

[Problems to be solved by the device]

 In the above conventional apparatus, the lower filter cloth moves in the original flat state of the filter cloth except for the return side and feed side tow molding sections, but in the area of the tow molding section at the intermediate section of the feed side, the lower filter cloth rises and falls. It is forcibly bent at a right angle through the side plate. Therefore, the lower filter cloth is likely to have wrinkles in the bent portion and its vicinity. For this reason, in order to suppress the occurrence of wrinkles, for example, the lower filter cloth needs to be relatively strongly pulled and tensioned so that wrinkles do not occur on the tofu molding surface which is the bottom surface of the filter cloth.

However, since the lower filter cloth is bent, it is not possible to apply uniform tension, and the filter cloth itself is constantly repeatedly bent and stressed due to tension, which is a serious disadvantage. As a result, the bent portion and the portion in the vicinity thereof are particularly quickly damaged, which is extremely shorter than the original life of the filter cloth when it is not used in this manner.

An object of the present invention is to provide a completely new tofu automatic molding machine which can prevent the lower filter cloth from being damaged as described above.

[0010]

[Means for Solving the Problems]

 The above-mentioned problems of the present invention are as follows: a plate conveyor which is horizontally provided so that a lower filter cloth is placed on the upper surface thereof, a position regulating means which stands upright on both side surfaces of the plate conveyor, and a sieve raw material between the pressure conveyor above the plate conveyor. In a tofu automatic molding machine configured to continuously supply a rod-shaped tofu dough, and the lower filter cloth is configured to be always kept flat in the tofu molding region. In addition, a pair of left and right side wall conveyors, whose lower ends are moved in the same speed and in the same direction as the lower filter cloth, are arranged side by side on both side edges of the upper surface of the lower filter cloth. Can be solved by machine.

[0011]

[Action]

 In this way, the present invention allows the lower filter cloth to move in a series of flat states without being bent in the tofu molding region which is the middle part, and instead of not bending the lower filter cloth, the lower filter cloth is moved at a constant speed. The pair of left and right side wall conveyors that move at the same time can be arranged side by side to form a required tow molding region between these side wall conveyors and the upper surface of the filter cloth conveyor on the feed side.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the tofu molding machine of this embodiment. FIG. 2 is a schematic plan view of the tough molding area in this embodiment.

In FIGS. 1 and 2, the lower filter cloth 1 is mounted and stretched on a plate conveyor 2 as in the conventional apparatus. The lower filter cloth 1 is always composed of a series of flat surfaces on both the feeding side and the returning side. A pair of left and right side wall conveyors 3, 3 are provided so as to face the left and right side edges of the lower filter cloth 1 at least over the tofu molding region, with the lower edges close to each other.

The side wall conveyors 3 and 3 are stretched over front and rear pulleys 4, 5, 4 and 5 which are erected on the base with the lower filter cloth 1 interposed therebetween, and flat upright surfaces face each other. It has a structure like this. The pair of side wall conveyors 3, 3 are driven in the same direction as the lower filter cloth 1, that is, the plate conveyor 2, and at a constant speed. The structure of the side wall conveyor 3 is such that the portion of the stainless steel standing plate 9 fixed to the chain 8 is slidably guided along the plate conveyor 2 to the guide rails 6 and 6 provided on the base. It can be configured.

Therefore, through the lower filter cloth 1 held by the side wall conveyors 3 and 3 and the plate conveyor 2 and the upper filter cloth 10 held by the pressure conveyor 7, a tofu molding section a having a rectangular cross section is always formed. Are formed. The pressure conveyor 7 is arranged in parallel with the plate conveyor 2 at a constant interval as in the conventional case, and the upper filter cloth 10 is positioned below the pressure conveyor 7 as in the conventional case. It is provided.

With this configuration, the lower filter cloth 1 can be moved in a series of flat states in the tofu molding region without being bent, and an unnecessary load is not applied to the lower filter cloth 1. The required toughening zone can be formed.

In the illustrated embodiment, the side wall conveyors 3 and 3 are formed in the shape of a plate conveyor in which a short rail-shaped stainless steel standing plate 9 is fixed to the outer surface of each chain 8 forming an endless chain. The chain is engaged with the front and rear pulleys 4 and 5 composed of sprocket wheels to move at a constant speed with the lower filter cloth 1. The material of this conveyor is a filter cloth or a water-permeable porous plate. Needless to say, it may be a belt or may be variously modified as long as it forms side walls cooperating with both side edges of the upper surface of the filter cloth conveyor 1, not necessarily water permeability.

The drive system of each of the conveyors may use a different power source, but in order to at least completely match the moving speeds of the conveyors in the molding area, the structure is such that they are driven by the same power source. This is preferable because it becomes easy to synchronize the transport speed of each conveyor simply by mechanical means such as a speed reducer.

As described above, according to the present invention, the lower filter cloth is moved in a series of flat states without being bent in the tofu molding region which is an intermediate portion, and instead of bending the lower filter cloth, the moving speed of the lower filter cloth is not changed. A pair of left and right side wall conveyors that move at a constant speed can be juxtaposed to form a required tofu forming area between these side wall conveyors and the upper surface of the filter cloth conveyor on the feed side.

[0020]

[Effect of the device]

 As described above, the present invention makes a pair of left and right side wall conveyors 3 and 3 standing on a separate base stand on the upper surface of the lower filter cloth 1 which moves as a flat surface, and these side wall conveyors 3 and 3 and the plate are placed side by side. With the lower filter cloth 1 held by the conveyor 2 and the upper filter cloth 10 held by the pressure conveyor 7, it is not necessary to bend the lower filter cloth 1 as in the conventional case to form the rectangular tofu-forming part a. Therefore, the lower filter cloth is not damaged as in the conventional one, and the plate conveyor 2 supporting the lower filter cloth 1 is a single belt conveyor and the undulating side plate and the like are not necessary. Since the structure is simple and there is no difficulty in forcing the undulating side plates to stand upright through the guide rails, it is extremely efficient without considering the wear of each part.
