Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically cutting tofu to a predetermined size and packaging the tofu.

[0002]

2. Description of the Related Art In a conventional automatic tofu cutting and packaging apparatus, warm tofu immediately after production is cut into a certain size in a water tank and packed in a pack, so that the water temperature in the water tank rises, pollutes and propagates various bacteria. Not only that, but the sewage in the water tank is packed together with the fixed-size tofu in the packaging pack, which causes deterioration in quality due to turbidity and deterioration in storability due to warm water and various bacteria (JP-A-2-186957). Issue). In addition, there is a device for sandwiching a single-size cut tofu with a sandwich plate and storing it in a packaging pack on a conveyor, but there is a problem that soft tofu is destroyed by the sandwiching force of the sandwich plate.

[0003]

SUMMARY OF THE INVENTION The present invention uses two aquarium tanks for both relatively soft tofu and hard tofu to cool the slicing tofu of high temperature immediately after production and to cool the fresh water of relatively low temperature with less turbidity. Another object of the present invention is to obtain an automatic tofu cutting and packaging device with good quality and high storability that can be packaged in a packaging pack.

[0004]

In order to achieve the above-mentioned object, the present invention provides a movable machine frame which moves between two water tanks from one side to the other and which can move in and out of both of the water tanks. Providing a plurality of sets of tofu constant-size cutting partition plates at regular intervals, and providing the machine frame with a reciprocating tofu pushing plate facing each partition plate of each set and a reciprocating bottom plate facing each partition plate of each set. , Tofu automatic cutting and packaging device with a fixed-size tofu packaging box transfer conveyor installed in the other water tank On one water tank side, the partition plates of each set are close to each other, and in the other water tank, to the holding frame provided on the transfer conveyor. The tofu automatic cutting and packaging apparatus according to the invention, in which an expanding / contracting device for expanding the adjacent width of each partition plate of each set is provided immediately above the packaging box to be held, the reciprocating tofu pressing plate is vertically movable, and the tofu upper surface pressing plate. 1 automatic tofu cutting and packaging device according to the above-mentioned first or second invention The first was divided into two aquarium fish tank by a partition wall, constituted by tofu automatic disconnection packaging apparatus described respectively in the second or third invention.

[0005]

Therefore, the long rectangular tofu 12 'before sizing is moved toward the sizing cutting partition plate 4 by the reciprocating tofu pushing plate 5 as shown in FIG.
When the tofu 1 is slid from the position shown in FIG. 2 to the position shown in FIG.
2 ′ is cut to a fixed size by the tip blade 4 ′ of the partition plate 4, enters between the partition plates 4 and 4 of each set, and is supported on the bottom plate 6 that forms the bottom of the partition plates 4 and 4. In this state, the movable machine frame 3 is raised above one of the water tanks 1, further moved above the other water tank 2, and then lowered toward the transfer conveyor 7 in the other water tank 2. At that time, the adjoining width w between the partition plates 4 and 4 of each set is expanded by the expansion / contraction device 10, and the sized cut tofu 12 in each of the partition plates 4 and 4 of each set is sized by a plurality of fixed sizes supported by the conveyor 7. The tofu packaging boxes 9 and 9 are arranged immediately above (dotted line in FIG. 3 and phantom line in FIG. 6). In that state, the bottom plate 6
3 is slid from the position shown in FIG. 3 to the position shown in FIG. By doing so, the upper pressing plate 11 is lowered, so that the tofu 12 is forcibly accommodated in the packaging box 9 by the pressing plate 11 (see FIG. 5). Thereafter, the conveyor 7 moves to stop the empty packaging box 9 at that position, returns to the original position shown in FIG. 1 by the operation reverse to the above, and repeats the same operation as described above.

[0006]

EXAMPLE A partition 14 is provided on the common bottom plate 13, and the partition 14
First and second water tanks 1 and 2 are formed on both sides of, and a movable machine frame 3 that reciprocates between the water tanks 1 and 2 is provided. The water tanks 1 and 2 may be independent of each other without the partition wall 14. Then, a plurality of sets of tofu constant-size cutting partition plates 4 are attached to the machine frame 3 via a downward link rod 3 ',
The base end of 4 is fixed via the end plate 4 ″, and the tip ends of the partition plates 4 and 4 that are close to each other are contacted to form a sizing blade 4 ′ as shown in FIG. (C) As shown in the figure, it does not matter if the adjacent partition plates 4 and 4 are arranged at the base of the fixed sizing blade 4 '. The interval t (Fig. 7) between the pair of partition plates 4 and 4 is the tofu 1
The constant interval t is equal to the fixed size of 2. Further, the machine frame 3 is provided with a tofu pushing plate 5 which can be reciprocally slid toward the fixed interval t, and a perforated bottom plate 6 for draining can be reciprocally slid at the bottom of the fixed interval t. However, the non-perforated bottom plate 6 may be provided.

As shown in FIG. 4, the bottom plate 6 reciprocates to the left of the partition plate 4, and the pushing plate 5 reciprocates from the right side to the left side in FIG. 1. The racks 15 fixed to the machine frame 3 respectively. Alternatively, it can be reciprocated through the downward link rods 19 and 20 by the laterally moving pinion 17 or the fixed pinion 18 which meshes with the sliding rack 16 (see FIG. 1). Further, the pushing plate 5 is provided on a vertical rack 22 which is supported by a guide guide 21 of the lateral pinion 17 so as to be able to move up and down through the downward link rod 20, and a meshing pinion 23 provided on the guide guide 21 is provided on the vertical rack. 22
It is possible to move up and down by engaging with the upper surface of the pressing plate 5, and the upper pressing plate 11 of the cut tofu 12 is provided above the pressing plate 5. The first (one) water tank 1 is provided with a support plate 24 for supporting the rectangular tofu 12 'before sizing, and the second (other) water tank 2 is provided with an intermittent tofu packaging box 9 intermittently. A transfer conveyor 7 is provided.

In the first water tank 1, each set of the partition plates 4,
4 are close to each other (FIGS. 7 (a) and (b)), and in the conveyor 7 in the second water tank 2, since the packaging boxes 9 and 9 are held between the holding frames 8 and 8, The adjacent width w between the partition plates 4 and 4 is increased. The machine frame 3 includes the partition plates 4 and 4 of each set.
A plurality of space enlargement / reduction devices 10 are provided for each of the machine frames 3 and 3 to connect the machine frames 3 and 3, and the adjacent width w of the partition plates 4 and 4 of each set can be enlarged / reduced and adjusted by the operation of the device 10. In the second water tank 2, each set of partition plates 4 and 4 is arranged directly above the packaging box 9 of the conveyor 7. The expansion / contraction device 10 is one in which the links shown in FIGS. 8 and 9 (a) (b) are expanded / contracted by a cylinder, and each set of the partition plates 4 and 4 may be provided on the link. Reference numeral 25 in FIG. 6 is a supply guide plate for the uncut tofu 12 ', and 26 is a supply cylinder.

[0009]

Since the present invention is constructed as described above, the uncut tofu 12 'can be cut to a fixed size in one of the water tanks 1, and the fixed-size cut tofu 12 once rises in the air, Since it is cooled by the relatively cold fresh water in the other water tank 2 and at the same time it is packaged together with the relatively cool fresh water in the packaging box 9 (packing pack) and carried out, the packed tofu having good quality and excellent preservation is compared. There is an effect that can be obtained quickly. In addition, soft tofu can be safely packaged without fear of breaking even if it is relatively soft.
