BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described.
The case of applying it to a machine for packaging squid somen will be described in detail as an example. For the sake of convenience, parts having the same functions are designated by the same reference numerals, and the description thereof will be omitted.

Reference numeral 1 denotes an object input section, which is an input conveyor 3 made up of a belt conveyor into which squid 2 which is an object is input, and a belt conveyor which transfers the cut squid cut into squid somes 2a to a second transfer conveyor 11. And a squid cutter 5 that cuts the squid 2 into squid somes 2a, which is provided between the loading conveyor 3 and the first transport conveyor 4. 6 is the above squid cutter 5
Is a receiving roller for the squid 2 and acts as a cutting board when the squid 2 is cut. Reference numeral 7 is a squid interval confirmation sensor for confirming the interval between the cut and conveyed squid somes 2a, and 8 is a sheet start sensor for issuing a start command for the sheet 12, both of which are provided at the end of the first conveyor 4.

The transport section 10 is a second belt conveyor.
The squid somen 2a is placed on the film-shaped sheet 12 which is composed of the transport conveyor 11 and is fed endlessly from the sheet roller 13 and is transported to the next sheet cutting unit 20.

FIG. 3 shows the details of the transport unit 10. The endless sheet 12 attached to the sheet roller 13 passes through a tension roller 14 and a free roller 15 that freely move up and down to adjust the tension of the sheet 12, and then the drive roller 1
6, the sheet is fed onto the second conveyor 11. 17
Is a sheet pressing roller that presses the sheet 12 onto the second conveyor 11.

The sheet cutting unit 20 is composed of a third conveyer conveyor 21 which is a belt conveyor, and cuts the above-mentioned sheet 12 into one packaging sheet 12a with the squid somen 2a placed thereon.

FIG. 4 shows details of the sheet cutting section 20. A sheet cutter 22 is provided at the starting end of the third conveyor 21.
Is provided. The sheet cutter 22 includes a motor 23
By a cylinder 25 of a rodless cylinder that is rotatably mounted on a table 24 of a rodless cylinder, and moves in the width direction of the seat 12 (shown by arrows A and B in FIG. 5) together with the motor 23. Sheet 12
Is cut into one packaging sheet 12a.

Frames 26 are provided upright on both sides of the starting end of the third conveyor 21 (only one frame is shown in FIG. 4 for convenience). The frame 26 is the above table 24
Is fixed, and an operation box 27 is attached to the upper part.

A pair of air cylinders 29 for raising and lowering the sheet fixing plate 28 are attached to the frame 26. The sheet fixing plate 28 fixes the endless sheet 12 at the time of cutting.

Reference numeral 30 designates a pair of sheet pressing rollers for pressing the packaging sheet 12a onto the third conveyor 21;
Is a sheet remaining confirmation sensor for confirming the remaining amount of the rolled sheet on the sheet roller 13.

The sheet folding section 40 is a folding bar 4 which can be raised and lowered.
1, the folding bar 41 projects upward just before the squid somen 2a placed on the packaging sheet 12a,
As the squid somen 2a progresses, the packaging sheet 12a becomes two
Fold it in half and wrap the squid somen 2a.

FIG. 6 and FIG. 7 show details of the sheet folding section 40. The folding bar 41 is a bar provided in the width direction of the packaging sheet 12a and can be moved up and down by an air cylinder 42. Reference numeral 43 is a ball bush for guiding the vertical movement of the folding bar 41.

An air blow 4 is provided just below the folding bar 41.
4 is provided. The air blow 44 is preferably installed obliquely so that the blowing of the air 45 slightly intersects with the packaging sheet 12a.

Reference numeral 51 denotes a buffer conveyor which is a belt conveyor, and conveys the squid somen 2a packaged with the packaging sheet 12a in the process of freezing and bagging.

The packaging machine according to the present invention operates as follows. First, the squid 2 is placed on the loading conveyor 3.

Next, the squid cutter 5 cuts the squid 2 into a soybean-like shape (squid somen 2a).

Next, the seat start sensor 8 detects the squid which has become the squid somen 2a.

Then, the driving roller 16 is actuated, and the sheet 1
2 is fed onto the second conveyor 11. It should be noted that the sheet 12 for the first operation is fed to the second conveyor 11 in advance.

At the same time, the second transfer conveyor 11 is driven, and the squid 2 on the first transfer conveyor 4 transfers to the second transfer conveyor 11.

Next, the seat 12 is fixed by the seat fixing plate 28.
Is fixed, and the sheet 12 is cut by the sheet cutter 22. As a result, one packaging sheet 12a is formed.

Squid 2 placed on the packaging sheet 12a
The sheet a moves to the third conveyor 21 of the sheet cutting unit 20 and is further conveyed.

In the third transfer conveyor 21, the packaging sheet 1 is
The folding bar 41 projects immediately before the squid 2a which is carried on the 2a and conveyed. The timing at which the packaging sheet 12a comes to the top of the folding bar 41 is set by a timer in a sequencer (not shown) in the operation box 27.

As a result, the folded packaging sheet 12a
Since the squid 2a passes underneath, the sheet 12 is folded in two with the progress of the packaging sheet 12a and the squid 2a placed thereon.

When the folding bar 41 is projected, the air blow 44
Operates to facilitate the folding of the packaging sheet 12a. This is because the packaging sheet 12a is prevented from being sandwiched between the conveyors 21 and 51 at the time of transfer of the conveyor. The packaging sheet 12a is configured to be folded at a position that divides the squid 2a into substantially equal parts.

The squid 2a wrapped with the packaging sheet 12a is transferred from the third conveyor 21 to the buffer conveyor 51.
To move to the next step. That is, the squid 2a packaged by the packaging sheet 12a is frozen in this state, and after frozen, it is packed in bags and shipped.

In the above, packaging of the cut squid 2a is automatically performed through a series of steps,
Contributes to speeding up work. In this example, the number of workers was changed from 5 to 2. Therefore, it also contributes to cost reduction.

Moreover, since no human hands are involved in the packaging process, it is hygienic. Moreover, since the number of workers on the site is reduced, this is also advantageous in hygiene.

Further, conventionally, since the sheet-like sheet 12 is used, it is necessary to manage for one day, but according to the present invention, since the roll-shaped sheet 12 is used, the management is unnecessary. Become. In addition, since a relatively low cost roll sheet is used, this also contributes to cost reduction.

The packaging machine according to the present invention is not limited to the above embodiment. For example, the type of conveyor forming each part does not matter.

The folding position of the packaging sheet 12a is arbitrary as long as the cut squid 2 can be packaged, and may not be a bisected position. Depending on the conveyance speed of the sheet 12 and the timing of the protrusion of the folding bar 41, the dimensions of the upper and lower sheets after the object is wrapped and folded in half can be set arbitrarily.

The sheet folding section 40 may be made of any constituent member, and for example, a member which sucks air from above may be considered.

Any means may be used for cutting the sheet 12 into the packaging sheet 12a, and for example, heat rays or ultrasonic waves may be used.

The installation of the air blow 44 is optional.

The angle of air blown by the air blow 44 can be set appropriately. However, according to the above-mentioned embodiment, the wrapping sheet 12a is smoothly folded, which is more advantageous for quick work.

The type of object to be packaged is arbitrary. In addition to the squid somen as described above, for example, dried squid, dried fish, meat, agricultural products and the like can be applied as long as they are wrapped by folding the film-like sheet 12.

[0041]

As described above, according to the packaging machine of the present invention, it is possible to efficiently and hygienize the conventional manual packaging such as squid somen. Further, there is an effect of contributing to the cost reduction of the above-mentioned packaging work.
