Description

[Detailed description of the invention] The present invention is suitable for dividing an object to be processed, such as an ovary of a predetermined length, into multiple parts in the longitudinal direction, particularly in a pre-boiled state, in order to obtain an ovary, etc. that is wrapped inside the ovary. It is related to a cutter for cutting into parts.

Conventionally, in order to obtain the ovary that can be wrapped in the ovary, it has been carried out to cut the porpoise into a predetermined length and then divide it vertically into 4 to 8 parts, but this work originally required manual labor. This was done in a highly inefficient manner.

Therefore, some automatic dividing cutting machines have been proposed and put into practical use in order to automate the dividing work, but these cutting machines often have a structure that simply divides the parts into multiple parts, making it difficult to perform sufficient cutting. Instead, the cutting residue accumulates, greatly reducing the efficiency of dividing and cutting, and the current situation is that it has not been possible to carry out dividing and cutting that is industrially and commercially satisfactory.

Based on the current situation, the present inventor has conducted various studies with the aim of providing a cutting cutter suitable for efficiently and efficiently dividing the ovary, etc., and has first developed a tapered conical cutter. A plurality of thin blades are arranged along the generatrix of the virtual conical surface at predetermined intervals in the radial direction with respect to the central axis of the conical shape, and their tapered tips are gathered together by a gathering member, while the other end on the rear side is For example, we have proposed a dividing cutter that is fixed to a connecting member that is connected to the tip of a centering guide device for feeding out an ovary, etc., located on the machine frame side of an automatic dividing cutting machine.

However, when the ovary to be cut into pieces is still raw, the above proposal is extremely effective in terms of the need for strength to withstand the resistance when cutting the ovary into pieces. We have found that if it is possible to cut the fish into pieces with a beautiful cut surface, rather than just raising them at the end, it is possible to pre-boil them and then cut them into pieces, and we have found that this is more effective in terms of cutting efficiency. .

Based on this knowledge, when we observed the state of the cutter when it was cut into pieces, we found that since the previous cutter was fixed by a gathering member on the tip side, this created resistance and caused damage to the boiled ovary. I learned that it wasn't.

Therefore, the present invention aims to further improve the above-mentioned proposed dividing cutter so that it can work smoothly and efficiently on relatively flexible workpieces such as boiled ovaries. On the side, the objects are not fixed to an aggregating member, but are held in a free state each month, and the objects are aggregated in that state.

Hereinafter, specific examples of the cutter of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows an example of an automatic dividing/cutting mechanism using the cutting cutter of the present invention, in which objects A to be processed such as ovaries are predetermined in each transport case 3 of a transport conveyor 2 installed in a machine frame 1. The centering guide is supplied in the same length, is moved sequentially, reaches a predetermined position, and is protruded at the tip of the piston rod 5 by the operation of a fluid cylinder 4 such as an air cylinder, and is disposed at the protruding end. The figure shows a mode in which the sheet is sent to a device 6 and is accurately divided into a plurality of pieces by a dividing cutter 7 provided at the tip using centering guidance.

This mode is used as a simple and practical mechanism suitable for dividing and cutting ovaries, etc., regardless of their thickness, but in the case of thick ovaries, since there is a core in the inner core, it is not necessary to remove the core. It is necessary to do it.

FIG. 2 shows an example of a preferred mechanism for cutting the ovary into multiple pieces while simultaneously corening the ovary.

That is, in this mechanism, the ovary, which is the object to be processed, is transported by a conveyor belt (not shown) and dropped into the supply section 13 one after another, and then the ovary is transported at the tip of the piston rod 12 by the actuation of a separately provided fluid cylinder 11. After the feed is sent to the first centering guide device 14 and the outer diameter is made uniform by the outer diameter cutter 15, the supply receiver, which is arranged so that it can be sequentially moved from each working position by the turret shaft 16, is moved to the stopping position. It is sequentially sent to the second centering guide device located at a.

Then, when the object to be processed is sent out, it rotates around the turret shaft 16, and the centering guide device 6 that has received the object to be processed reaches the next centering position and performs the necessary centering operation. This is done in preparation for the next step of dividing and cutting.

In this way, once the centering is completed, the turret shaft 16 is moved again.
Each centering guide device rotates around , transports the centering-completed workpiece to the dividing and cutting position C, and in the same manner as in FIG. The object to be processed is brought to the cutter 7 for dividing and cutting, and the object is divided and cut.

The split cutting cutter 7 disposed at the end of each mechanism as described above is the main part of the present invention, and the details of the split cutting cutter 7 according to the present invention are shown in FIGS. 3 to 5. One example is shown.

That is, as is clear from these figures, the splitting cutter of the present invention is composed of a plurality of thin blades 7a arranged in a radial direction with respect to the central axis along the generatrix of the virtual conical surface of the conical shape. The narrowed end side is assembled in a free state without using any members, while the other expanded end side is a thin blade clamping extension section attached to the machine frame 1 at the tip of the centering guide device 6. It is fixed by a connecting member 9 with 10.

In this case, when attaching the thin blades 7a, first attach each thin blade 7a to the extending portion 10 of the connecting member 9 along the locus of an imaginary circle centered on the intersection of the central axes of the thin blades 7a to be gathered. An insertion slit 9' is made using a milling machine or the like, a part of the thin blade 7a is inserted into the slit 9', held using a jig, and fixed and integrated by brazing or the like.

In addition, when the thin blades 7a are assembled, the tips of the plurality of thin blades 7a may be assembled so that they touch each other at one point at the aggregated end, or they may be aggregated with a gap left in the center at the aggregated end. You can.

In particular, in the latter case, the passing dark resistance at the center is relaxed, so it is very effective depending on whether the object to be treated is thick, thin, or flexible.

In order to create a gap in the center of the aggregated end, a jig such as a wire material is inserted through the center, and a plurality of thin blades 7a are inserted and fixed into each slit in the clamping extension. After that, the wire can be formed by pulling out the wire material.

Further, as shown in FIG. 4, the connecting member 9 has a through hole 9b in its center for passing the object to be processed such as an ovary, and the thin blade holding extension portion 10 is provided around the through hole 9b in a predetermined manner. It extends integrally to the position.

Furthermore, when the ovary passing through the through hole 9b is relatively soft due to boiling, the guide 6a is made to protrude from the centering guide device 6 to ensure reliable feeding. A substantially semicircular hole portion 9C that smoothes the protrusion of the thin blade 7 is formed around the through hole 9B.
The guide 6a is provided in this portion 9C so as to avoid the position of the clamping extension portion 10 of a, and the guide 6a is projected from the centering guide device 6 toward the cutter 7 portion.

Thus, the splitting cutter 7 created above has a connecting member 9 attached to the tip of the centering guide device 6, but the connecting member 9 has a structure as shown in FIG. By doing so, it is possible to engage and disengage the locking pin 8 provided on the machine frame 1 side and perform simple connection.

In the above description, a plurality of thin blades 7a are provided, but the number of blades is normally selected as appropriate depending on the thickness of the object to be cut and the purpose of use, and is from 4 to 12 blades. is the most common.

However, the separate establishment is not bound to this.

In addition, it is of course possible to make appropriate modifications to each part of the present invention as long as it does not deviate from the above objectives.
This is also included in the present invention.

The present invention has a diagonal upward configuration. Next, we will describe how such a cutter is used to cut submunitions, etc. Boiled submunitions sent out by the centering guide device 6 in Figs. The object to be processed A such as
The object to be processed is fed into the cutter from the widening side where a plurality of blades 7a are arranged, and as it advances, the object to be processed comes into contact with the thin blade 7a from the narrowing side on the tip side, and moves outward from the center. A straight line is cut radially toward the target.

FIG. 6 shows the henchman thus cut into pieces.

During this cutting, it is extremely important that the cutting action occurs outward from the center of the object to be processed, and is similar to the action of pulling a knife to cut, rather than pushing it against the blade. This not only extends the life of the cutter, but also provides a substantially triangular or trapezoidal cross-section of the cut product, which is effective for stable divisional cutting.

In particular, the thin blade holding extension portion 10 also serves to reinforce the blade portion during divisional cutting.

In addition, in the case of cutting the object to be processed without going through the centering process as shown in Fig. 1, and in the case of dividing the object to be processed after core counting as shown in Fig. 2, the detailed structure of the cutter is changed to this. It is a good idea to make them different at the same time, and these changes are made by utilizing the connection and separation of the locking groove 9a and the locking pin 8.

As described above, the cutting cutter of the present invention has a plurality of thin blades arranged radially with respect to the central axis along the generatrix of the virtual conical surface, and has a tapered shape so that it can easily handle the workpiece being fed. Unlike conventional push-cutting, the cutter cuts radially outward from the center, making the cut surface smooth and strong enough to withstand the cutting force of the thin blade.
It is possible to improve the life of the knife.

Moreover, since the tip is concentrated but remains free, there is no resistance even in the case of a flexible object such as a boiled henchman, and there is no possibility of damage or incorrectness of the submunitions. It does not cause splitting, and fiber waste such as henchmen due to cutting does not accumulate inside the cutter, and the cutting ability can be maintained for a long time, greatly increasing the splitting efficiency. Due to the smoothness of the cutting, the tendency of the cut individual henchmen etc. to curve outward after being cut into pieces can be prevented, and high-quality divided henchmen etc. can be obtained.

The cutter of the present invention is particularly useful when cutting the henchmen used for ovary tempura into parts after boiling the henchmen in advance, and greatly increases production efficiency compared to the conventional method.
