Description

[Detailed description of the invention] (Field of industrial application) The present invention targets long dough products such as rod-shaped dough products, square-shaped continuous products, and band-shaped dough products, and processes the long dough products in the longitudinal direction. It relates to a device used to continuously make diagonal incisions (cuts or cuts) on a surface.

(Prior art) As a conventional cutting device of this type,
For example, the one described in Japanese Utility Model Application Publication No. 60-121779 is known.

The conventional device described in FIG. 1 of the publication has a roll cutter with a spiral cutting edge protruding from its outer circumferential surface and a roller with a smooth outer circumferential surface arranged in parallel, and the gap between the roll cutter and the roller. By passing the strip-shaped dough through the roll cutter, a diagonal cut was made from one side of the strip-shaped dough using the spiral cutting blade of the roll cutter.

Furthermore, the conventional device described in FIG. 5 of the publication is as follows:
A pair of roll cutters each having a protruding helical cutting edge with the same helix angle and opposite helical direction are arranged in parallel, and by passing a strip-shaped dough product between both roll cutters, the spiral cutting edge of both roll cutters can be cut. The structure was such that diagonal cuts were made on both sides of the strip-shaped dough product.

(Problem to be solved by the invention) However, in the case of the former conventional device, the spiral cutting edge of the roll cutter bites into one side of the strip-shaped dough, and the other side is fully supported by the roller, resulting in a single-sided cut. Therefore, the biting depth of the spiral cutting edge becomes deeper, and the force in the width direction acts on the strip-shaped dough product accordingly due to the inclination of the spiral cutting edge.
There was a problem in that the strip-shaped dough product gradually shifted to one side as the cuts were made.

In addition, in the case of the latter conventional device, since the spiral cutting blade of the roll cutter cuts into both sides of the strip-shaped dough product, the cutting depth is half the thickness of the strip-shaped dough product. Although this has the advantage of reducing the force acting on the strip-shaped dough product in the width direction and preventing the strip-shaped dough product from shifting, on the other hand, the spiral cutting blades of both roll cutters are both formed with sharp tips. Therefore, it is technically extremely difficult to arrange the spiral cutting blades so that they are exactly abutting each other, and if the setting is incomplete and the spiral cutting blades are misaligned,
There was a problem in that the cuts were disturbed, and especially when forming fibrous meat with short cutting intervals, the fibrous meat would fall apart, which would hinder subsequent processing.

(Means for solving the problem) The present invention was devised to solve the above-mentioned conventional problems, and its purpose is to accurately butt the spiral cutting edges together. An object of the present invention is to provide a continuous diagonal cutting device that can easily make continuous diagonal cuts.

In order to achieve this purpose, in the present invention, a pair of roll cutters each having a helical cutting edge with the same helix angle and opposite helical direction protruding from the outer circumferential surface is installed in parallel, and the spiral cutting edge of one roll cutter is The tip of the spiral cutting blade of the other roll cutter is formed with a sharp tip, and the tip of the spiral cutting blade of the other roll cutter is formed with a flat tip. Both roll cutters are arranged in a butt state where they are in contact or close to each other.

(Function) In the continuous diagonal cutting device of the present invention, when a long kneaded product is passed between both roll cutters, a diagonal cut is made into the long kneaded product to be processed by the spiral cutting blade as both roll cutters rotate. can be administered.

Since the cuts in this case are double-sided cuts made by a pair of roll cutters, the depth of bite of the spiral cutting blades becomes shallow, and it is possible to prevent the long kneaded product from shifting.

In addition, the tip of the spiral cutting blade of one roll cutter is formed sharply, and the tip of the spiral cutting blade of the other roll cutter is formed flat, so that both spiral cutting blades can be cut within the range of this flat tip. Even if there is a misalignment in the butt, there is no problem with cutting, and the roll cutter can be set more easily and an accurate butt can be obtained.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 4 show a first embodiment of a continuous diagonal incision device A that processes a rod-shaped dough product M as a long dough product.

This continuous diagonal cutting device A mainly includes a pair of roll cutters 1 and 2.

One of the roll cutters 1 has 16 helical cutting edges 10, 10, .

The other roll cutter 2 has 16 left-helical cutting edges 20, 20... protruding from its outer circumferential surface at the same twist angle as each of the spiral cutting edges 10 of the roll cutter 1, and the tip of each of the spiral cutting edges 20 is formed into a narrow flat surface.

Then, the two roll cutters 1 and 2 are set as a pair, and the spiral cutting edge 10 of one of the roll cutters 1 is
Both roll cutters 1 and 2 are arranged parallel to each other in a butting state where the sharp end portion 11 of the other roll cutter 2 and the flat end portion 21 of the spiral cutting edge 20 of the other roll cutter 2 are in contact with each other, and both roll cutters 1 and 2 are rotated in the same manner. It has a structure that allows it to rotate in the opposite direction at different speeds.

Therefore, when the rod-shaped dough product M to be processed is fed between the roll cutters 1 and 2 at a constant speed, as the roll cutters 1 and 2 rotate, the helical cutting blades 10 and 20 that are in abutting contact form a strip. The rod-shaped dough product M is continuously cut diagonally at intervals.

In this case, the spiral cutting blades 10 and 20 will bite into the rod-shaped dough M from both sides, so the amount of penetration of each spiral cutting blade 10 and 20 is half the wall thickness of the rod-shaped dough M. Since the amount of biting becomes shallower by that amount, it is possible to prevent the rod-shaped dough product M from shifting to one side.

The spiral cutting blades 10 of the roll cutters 1 and 2
20 are the sharp tip portion 11 and the flat tip portion 2
Since the roll cutters 1, 2 are butted against each other, the positional deviation of the sharp tip portion 11 can be tolerated within the range of the width of the flat tip portion 21 when the roll cutters 1, 2 are set.

Next, FIGS. 5 and 6 show a continuous diagonal incision device B according to the second embodiment.
It is used to form striped cuts n diagonally at narrow intervals in this strip-shaped dough N, and in this case, both roll cutters 3 and 4 each have a large number of spiral cuts with narrow pitches. The cutting blades 30, 40 are provided in a protruding manner, and both roll cutters 3, 4 are arranged so that the sharp end of one spiral cutting blade 30 and the flat end of the other spiral cutting blade 40 are brought into close contact with each other.
The arrangement is the same as in the first embodiment.

Therefore, when the strip-shaped dough N is passed between the roll cutters 3 and 4, streak-like cuts n, n are formed at narrow intervals.
... will be formed in a diagonal direction. Note that other functions are similar to those of the first embodiment described above.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration of the present invention is not limited to the above-described embodiments, and the present invention may be modified without departing from the gist of the invention. included in the technical scope of the invention.

For example, the processing target can be long dough products such as stick-shaped dough products, square-shaped dough products, and strip-shaped dough products made from fish meat, livestock meat, flour, dairy products, etc. In addition, fibrous meat products can be processed. It is also possible to process a so-called crab leg-shaped rod-shaped kneaded product obtained by gathering and bundling the crab legs as it is or in a film-wrapped state.

Further, the number of threads, pitch between threads, helix angle, etc. of the roll cutter are appropriately determined depending on the details of the cutting process.

In addition, in a device using a roll cutter, it is possible that the cut product may get stuck between the strips of the spiral cutting blade and become clogged. Alternatively, a pushing member that advances and retreats in the radial direction is provided on the bottom surface between the strips, and this is operated by a cam as the roll cutter rotates, and the product is removed by the advancing motion. It may be pushed out from between the rows.

(Effects of the invention) As explained above, in the continuous diagonal cutting device of the present invention, the cutting depth of each spiral cutting blade is shallow due to the double-sided cutting using a pair of roll cutters, so that the product can be cut easily. The applied force in the width direction is reduced, and it is possible to prevent the product from shifting.

Furthermore, since the tip of the spiral cutting edge of one of the roll cutters is formed into a flat surface, it is possible to easily and accurately butt the spiral cutting blades together when setting both roll cutters.
