Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for attaching adhesion prevention pieces between thin slices, which sequentially attaches adhesion prevention pieces for preventing adhesion between thin slices. This invention relates to materials that can be effectively used to prevent thinly sliced pieces of raw ham, smoked salmon, cheese, etc. from sticking together.

[Conventional technology]

When thin slices of raw ham, smoked salmon, cheese, etc. are scaled or stacked and vacuum packaged,
When the package is opened and served, the thin slices stick together due to the pressure applied during lining and vacuum packaging, making it difficult to separate the slices and often breaking them, resulting in loss. Furthermore, separation of thin slices is very time consuming.

In the present invention, an ultra-thin film is inserted between sliced pieces to prevent the sliced pieces from coming into contact with each other and to bring them into close contact.

As a conventional technology of this kind, Japanese Patent Application Laid-Open No. 59-93297
There are techniques described in the Publication No. 45-16071 and the Publication No. 16071 of the Special Publication.

That is, in the former case, one end of the wrapping paper, which is the material of the welding prevention piece, is pressed and adhered to the leading edge of the slab to be cut by a jet air flow, and then the leading edge of the slab is sliced with a blade. , a technique is described in which strips of paper are attached between the slices by cutting a wrapping paper adhered to a slab.

The latter also involves slicing by accelerating and ejecting the insert formed by this cut into the path of the thrown thin slice as soon as it cuts the insert material when the thin slice is thrown out of the knife. A technique for inserting an insert piece between the pieces is described.

[Problem to be solved by the invention]

However, all of the above-mentioned conventional techniques have a structure in which the wrapping paper and the inserting material, which are the raw materials for the adhesion prevention piece, are fed into the cutting area of the thin slice, which makes the feeding device for the material for the adhesion prevention piece extremely complicated. There is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a structure for supplying a film, which is a raw material for the adhesion prevention pieces, and an apparatus for attaching the adhesion prevention pieces between thin slices, which can simplify the structure of the entire apparatus.

〔Example〕

FIG. 1 is a partially cutaway front view showing a device for preventing adhesion between thin slices, which is an embodiment of the present invention, and FIG. 2 is a plan view thereof.

In this embodiment, the device for attaching a piece to prevent adhesion between thinly sliced pieces according to the present invention thinly slices an object 3 such as a ham, and attaches an extremely thin film 6 between the thinly sliced pieces 4. It is configured to be equipped with a prevention piece 15. This apparatus for attaching pieces to prevent thin slices from sticking together is equipped with a conveyor belt 5, and the conveyor belt 5 is endlessly wound around a conveyor belt holding frame 17 which is open only at the top surface except for the downstream end. There is. A large number of pores 5a are arranged in the conveyor belt 5 in the conveying direction, and the holding frame 17
It is designed to communicate with the inside. Holding frame 17
An intake pipe 9 is fluidly connected to the holding frame 17, and the intake pipe 9 is connected to a blower (not shown) or the like to evacuate the inside of the holding frame 17 under reduced pressure.

The conveyor belt 5 is configured to be intermittently fed by a drive device (not shown) including a servo motor or the like. A fixed size feed roll 16 is circumscribed on a part of the conveyor belt 5 so as to rotate in conjunction with the conveyor belt 5, and a conveyor fixed size feed cam 7 is fixed to this roll 16 so as to rotate together with the conveyor belt 5.
A conveyor fixed-length feed switch 8 is disposed in conjunction with this cam 7, and based on this switch 8, starting and stopping of intermittent feed in the drive device of the conveyor belt 5 is controlled. .

A film reel 6A is installed below the conveyor belt holding frame 17, and this reel 6A is rotatably mounted on a shaft. An extremely thin film 6, which is a material for the adhesion prevention piece 15, is wound around the reel 6A, and the end of the winding of the film 6 is unwound. The unwound film 6 is wound around the upstream end of the conveyor belt 5 in the transport direction, and is held on the conveyor belt 5 by suction through its pores 5a.

At the upstream end of the conveyor belt 5, a thin slice supply device 1A is installed. In this embodiment, the feeding device 1A is equipped with an object holding plate 2, which holds an object 3, such as a cylindrical ham, in a vertical position, and It is configured to feed in pitches in the direction. Further, a round knife 1 is installed at the lower end of this holding plate 2, and this round knife 2 is configured to advance and retreat in a direction parallel to the feeding direction in conjunction with the intermittent feeding of the conveyor belt 5. . By moving forward while rotating, this round cutter 2 rotates to cut the workpiece 3.
The end portion of the plate is cut into thin slices 4 having a predetermined thickness. Along with this cutting, the thin slices 4 are sequentially placed on the film 6 held on the conveyor belt 5.

On the other hand, an alignment plate 12 is provided outside the downstream end of the conveyor belt 5.
2 is configured to be moved toward and away from the drive device (not shown) in substantially the same direction as the moving direction. Furthermore, fixed scissor blades 10 and movable scissor blades 11 are installed between the downstream end of the conveyor belt 5 and the alignment plate 12.
By cutting the film 6 bridged between the conveyor belt 5 and the alignment plate 12, the adhesion prevention piece 15 is attached to the lower surface of the thin slice 4 on the alignment plate 12 side.
It is adapted to be substantially formed and installed.
Furthermore, a receiving tray 13 is installed directly below the alignment plate 12 as a receiving device for receiving the thin slices 4 that fall as the alignment plate 12 moves away from the alignment plate 12 via an adhesion prevention piece 15. is configured to move vertically.

Next, the action will be explained.

A workpiece 3 held on a workpiece holding plate 2 is cut by a circular knife 1 that rotates and reciprocates. At the falling point of the cut thin slices 4, they are held in a sealed conveyor belt holding frame 17, which operates intermittently in conjunction with the reciprocating movement of the round cutter 1 (i.e., it stops while the object is being cut). However, during the return process of the round cutter 1, it moves a certain distance, that is, one rotation of the fixed size feed roll 16.) A conveyor belt 5 is provided. This conveyor belt 5 is provided with pores 5a, and the ultra-thin film 6 is adsorbed by air taken in through an intake pipe 9. Therefore, the ultra-thin film 6 is transported as the conveyor belt 5 is moved intermittently.

The thin slices 4 cut by the round knife 1 fall one after another onto the ultra-thin film 6 adsorbed on the conveyor belt 5.

The conveyor belt 5 starts moving in conjunction with the movement of the round knife 1, that is, in response to a signal pulse when the round knife 1 is at its most advanced position (when cutting is finished). When the size feed roll 16 rotates once, the conveyor belt 5 is stopped by the operation of the conveyor size feed cam 7 fixed to the size feed roll 16 and the conveyor size feed switch 8.

The thin slices 4 that have been sequentially cut and transported are
It passes through the fixed scissor blade 10 and the movable scissor blade 11 and is transferred onto the alignment plate 12. At the end of the conveyor belt 5 where the thin slices 4 are transferred to the alignment plate 12, the film 6 is not attracted.

The alignment plate 12 moves in the horizontal direction in conjunction with the movable scissor blades 11. The alignment plate 12 moves to the right end (dotted line) just before the movable scissor blade 11 cuts the ultra-thin film 6, and transfers the thin slice 4 on the ultra-thin film 6 onto the thin-slice tray 13 or It is dropped onto the thin slices 4 stacked on the tray 13. That is, the ultra-thin film 6 carrying the thin slices 4 is cut after contacting the thin slice tray 13 (as described later, in the case of a scale row, the conveyor belt 18) or the preceding thin slice 4.

Furthermore, the movable scissor blade 11 starts lowering in response to a signal pulse emitted when the round blade 1 is in its last retreat (before the start of cutting the object 3). At the same time, the alignment plate 12 also starts moving in the horizontal direction. The movable scissor blade 11 further descends, and the alignment plate 12 completes its movement just before cutting the ultra-thin film 6, dropping the thin slice 4 on the ultra-thin film 6 as described above. That is, the ultra-thin film 6 of the movable scissor blade 11
The cutting is performed while the round knife 1 is cutting the workpiece 3, that is, while the conveyor belt 5 is stopped.

Further, the thin slice receiver 13 adjusts the distance between the upper end of the thin slice 15 on the thin slice receiver 13 and the alignment plate 12 by the operation of a slice height sensor 14 that detects the height of the thin slice 15 on the thin slice receiver 13. always keep constant.

Note that the thin slices 4 may be arranged in a scale-like manner by falling onto a conveyor belt 18 installed below the alignment plate 12, as shown in FIG.

According to the embodiment described above, the following effects can be obtained.

(1) Because the ultra-thin film is fed using a conveyor belt that absorbs it, mechanically there are problems with inertia of the ultra-thin film that moves intermittently and problems with film sagging. This makes it possible to obtain a film feeding means that has a very simple structure and is free from failure.

(2) Since the film is cut with scissors, the minimum amount of film required is sufficient, and there is no wastage of film, making it economical.

(3) Since the process of cutting the object to be cut and the process of cutting the film and stacking and arranging the thin slices are separated, it is possible to process about 100 pieces per minute, making it extremely efficient.

(4) Raw ham, smoked salmon, cheese, etc. that are separated by ultra-thin film after opening the vacuum package are insulated from the air on both sides by the film, so they are less likely to dry out and are very effective in maintaining freshness. .

(5) When plating after opening the vacuum package, thin slices can be separated quickly and without any difficulty, so there is no damage or loss, and the plating can be done neatly.
And it can be executed cleanly.

(6) Even when stored in the refrigerator, both sides are not exposed to air, making it difficult to dry out, making it difficult to lose weight and maintaining freshness.

〔Effect of the invention〕

As explained above, according to the present invention, the structure is simple, there is no failure, the amount of film used is minimal and there is no waste, high-speed operation is possible at 100 sheets per minute, and when stacking can be stacked up to a height of about 50 cm, and it is possible to obtain a device for attaching pieces between thin slices to prevent sticking between thin slices, which can pack unsliced raw ham, etc.
