Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tofu packaging apparatus, and more particularly to an apparatus for automatically placing tofu into packaging packs.

Due to the nature of tofu that is extremely easily damaged, it has been impossible to automatically or mechanically perform the process of packaging tofu, including placing the tofu in a plastic pack.

For this reason, conventionally, putting tofu in a pack was done manually, and then covering it with a plastic sheet was done mechanically.

Therefore, packaging of tofu has been extremely inefficient and time-consuming.

As described above, the present invention provides a new tofu packaging device that automatically packs tofu, which has traditionally been a bottleneck in tofu packaging. This is an extremely useful invention because it can be carried out automatically by a machine.

Hereinafter, a device according to the present invention will be specifically explained based on an illustrated embodiment.

In Figure 1, reference numeral 1 denotes an endless chain that is tilted upward to the left and hooks onto each pair of sprockets 2 (only the upper sprocket is shown) in a direction perpendicular to the paper surface. be.

A series of top plates 3 are fixed to the pair of chains 1 at intervals, and these constitute an endless conveyor A for conveying tofu by placing tofu T on these top plates 3. There is.

The right end of this endless conveyor is in one end of water tank C (see Figure 4) which stores tofu cut to a predetermined size. do.

In the area of the endless conveyor A where tofu is conveyed, a pair of tofu guides 5 are fixed to a pair of metal fittings 4 as shown in FIG.
is installed to regulate the position of tofu being transported.

An ear piece 31 is formed at the rear end of the top plate 3 in the traveling direction to regulate the position of the tofu in the front and back direction.

Above the endless conveyor A, chains 7 are connected to each pair of sprockets 6 and are arranged in pairs in the direction of the paper.
is installed.

Pack guide bars 8 are attached to the chain 7 at predetermined intervals, and a pack P is supplied one by one from a conventional pack feeder (not shown) in the direction of the thick arrow, and is supported by the pack guide bar 8 as shown in the diagram. An endless pack transport conveyor B is configured to transport packs P in synchronization with the transport of tofu by conveyor A.

A pack reversal guide 9 for supporting the pack P so that the pack P does not come off is disposed outside the sprocket 6 on which the transport pack P is reversed.

In addition, the conveyor B in the area where the pack P faces downward
As best shown in FIG. 3, a chain rail and pack receiver 1o is provided below the pack to support the pack and prevent it from falling off.

In addition, in FIG. 3, reference numeral 11 indicates a pair of guides that regulate the left and right positions of the bag.

The pack P conveyed by the conveyor B is synchronized with the conveyance of the tofu by the conveyor A, and is gradually placed on the tofu T on the conveyor A in an inclined state while being conveyed in the quantity direction as shown in FIG. Go, chain rail and pack receiver,
It comes off the support provided by 10 and rests on the tofu.

On the outside of the upper left end to the tofu conveyor endless conveyor (′!.

A pair of endless chains 14 are disposed that extend around the sprocket 12 and the guide 13, and a tofu pack support bar 15 is attached to the endless chain 14.

16 is a reversal guide for a pack containing tofu.

After the pack containing tofu is turned over, it is discharged facing upward and transferred to the next packaging process.

Next, the operation of the device described above will be explained. Fourth
As shown in the figure, a tofu T cut to a predetermined size is placed in a water tank C, and this tofu T is transferred manually or by other appropriate means to an endless conveyor conveying tofu that is placed in the water tank C. They are placed on the top plate 3 of A, and are sequentially lifted and conveyed as shown in FIG.

On the other hand, packs P transported by endless pack transport conveyor B
is reversed so that it faces downward, and is conveyed in the same direction and at the same speed in synchronization with the conveyance of tofu on conveyor A.

As the tofu is transported, the pack P facing downward and the tofu T gradually approach each other, and the pack P is gradually placed on the tofu in an inclined state, and while air is exhausted from the bottom of the pack, the tofu is placed inside the pack and the pack is closed. When the tofu is removed from conveyor B, it is placed in a pack facing downward.

The downward facing pack containing tofu is guided by the bar 15 and the reversing guide 16 at the end of the conveyor A, and is reversed upward.
It is turned upward and transported to the next packaging process on a conveyor or the like as appropriate.

The above-described action can be seen in the movement of the tofu T and the pack P as shown in FIG.

In addition, in the embodiment described above, specific examples have been explained as the endless tofu conveyor A, the endless pack conveyor B, and the reversing mechanism, but the present invention is not limited to these, and any suitable structure may be adopted. Needless to say.

In addition, in the above-mentioned embodiment, the endless tofu conveyor is
One end of the tofu is placed in a water tank, and the tofu is transported from within the water tank, but this is just an example, and the tofu cut to a predetermined size is fed onto the tofu transport conveyor using a conveyor or the like. The key point is to feed the tofu onto the tofu conveyor using an appropriate means, place the tofu at predetermined intervals, and convey the tofu.1. It is fine as long as it can be done.

Furthermore, in the illustrated embodiment, the tofu conveying endless conveyor has an inclined part that gradually rises after tofu is placed thereon, but the running trajectory of this conveyor is also inclined relative to the tofu, and the tofu is packed. It goes without saying that an appropriate design may be adopted in the design of the machine as long as it can be covered.

Furthermore, any suitable structure for placing tofu on the endless tofu conveyor may be adopted.

The device according to the present invention covers tofu that is being carried on a conveyor from above with the pack tilted relative to the tofu. By expelling air from the bottom of the pack, you can smoothly put tofu inside the pack.

Therefore, in the apparatus according to the present invention, the tofu is smoothly placed in the pack while being placed on the conveyor, and the tofu is not damaged when being placed in the pack.

As described above, according to the apparatus of the present invention, the work of putting tofu inside a pack by hand can be done mechanically and automatically, so that tofu can be packed extremely efficiently and hygienically.
