Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tool for cutting cakes, etc., using a long band blade with excellent flexibility.

[Conventional technology]

Conventional cutting tools that are installed in a cutting device and are directly involved in cutting objects such as cakes, breads, processed meat products, and seaweed sushi rolls are shown in FIGS. 5 to 7.
As shown in the figure, a plurality of rigid linear cutting blades 2 with protrusions 1 caulked at both ends are attached to a pair of mounting members 3, 3 ( In Fig. 5, the left mounting member is omitted. It has a structure in which the cutting blade 2 is fixed (Jikko Sho 49-
18786, JP-A-61-241095).

[The problem that the idea aims to solve]

However, in the above-mentioned conventional structure, it is necessary to drill a hole in the cutting blade 2 and fit the protrusion 1 into the hole and caulk it, which increases the unit price of the cutting blade 2 and also requires the mounting member 3 and the spring member. 4, slit 3a,
Since it is necessary to form the mounting member 4a with high precision by electric discharge machining or the like, the costs of the mounting member 3 and the spring member 4 are also increased, resulting in a problem that the overall cost is increased.

The present invention aims to provide a cutting tool that can be manufactured at relatively low cost.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a cutting tool in which a cutting blade is attached to a pair of attachment members arranged in parallel with each other at an interval, in which each of the attachment members is fixed in a straight line by a fastening means. It is composed of a plurality of clamping blocks that are fastened together, and the cutting blade is a long, bendable band blade. a middle curved portion and one or more intermediate curved portions, the necks of these curved portions are sandwiched in the pinching grooves of the pinching blocks of each mounting member, and the portions between the pair of mounting members are aligned parallel to each other. A pair of mounting members are installed in a serpentine shape, and a regulating member for regulating the inner circumferential shape of each curved portion is individually inserted into each of the end curved portions and each intermediate curved portion, and a regulating member is individually inserted into the intermediate curved portion. One or more inserted regulating members are configured to be expanded diameter spring members.

[Effect]

The band blade portions aligned parallel to each other between the pair of attachment members serve as the cutting portion that actually cuts the object to be cut, such as a cake. No matter how many such cutting parts there are, there is no need to caulk a fixing protrusion to the band blade as in the conventional case. Further, since the neck of the curved portion of the band blade is sandwiched between the pinching blocks constituting the mounting member, the pinching blocks do not need to be machined with such high precision, and the cost is generally reduced.

The expanding diameter spring member inserted into the middle curved portion of the band blade pulls the band blade outward to keep it taut, so the band blade does not loosen.

〔Example〕

1 to 3 show an embodiment of the present invention, and in the figures, reference numeral 10 indicates a band blade. This band blade 10 is a long steel member with a blade 10a attached to one edge of the band-shaped long steel member, and has a structure that has excellent flexibility and can be freely curved. Also, code 1
Reference numeral 1 designates a pinching block, and the upper side surface has a pinching groove 11a for the band blade 10, and the outer surface perpendicular to the side surface (for the left pinching block 11 in FIG. 1, the left side surface and the right pinching groove 11a) In the block 11, arc-shaped depressions 11b are formed on the right side surface, a fixed edge 11c is protruded from the lower part, and a through hole 11d is bored in the center of the fixed edge 11c. ing.

The pinching blocks 11 are arranged in plurality (8 in FIG. 1).
) arranged in a straight line with their sandwiching grooves 11a facing each other and their through holes 11d aligned;
The tie bolts 12 are inserted into the through holes 11d and are integrally connected by tightening nuts 12a, thereby forming the mounting members A and B. Each mounting member A,
In B, the fixed edges 11c of each pinching block 11 are placed in the grooves 14 of the frame-shaped base 13 and held down with the presser metal fittings 15, the presser metal fittings 15 are fixed with bolts 16, and the base 1 is secured.
3 are attached parallel to each other on two opposing sides. The tie bolt 12 and nut 12a constitute a fastening means.

Further, the band blade 10 has both ends and a middle part curved in an arc shape to form two end curved parts 10b and six middle curved parts 10d on the outside of the mounting members A and B. Each neck portion 1 of the curved portions 10b and 10d

It is sandwiched between eleven clamping grooves 11a and 11a, and is installed in a meandering manner with the portions between the pair of mounting members A and B aligned parallel to each other.

Reference numeral 17 denotes a regulating member made of an enlarged diameter spring member with a C-shaped cross section. The regulating member 17 is inserted into each curved portion 10b, 10d of the band blade 10 and
While restricting the inner circumferential shape of b and 10d, it acts to expand the diameter and pulls the band blade 10 in the length direction to create appropriate tension. The regulating member 17 of the end curved part 10b of the band blade 10 is arranged at the concavely curved arc-shaped corner part 11e of the sandwiching blocks 11, 11 that are adjacent to each other.

Next, the operation of the cutting tool according to the present invention constructed as described above will be explained.

To attach the band blade 10 to the pair of mounting members A and B, loosen the nut 12a and bolt 16 to create a gap between the pinch blocks 11, 11, and fit the band blade 10 into the pinch groove 11a through the gap. At the same time, the restricting member 17 is reduced in diameter with an appropriate jig and inserted into each of the curved portions 10b and 10d of the band blade 10, and the entire band blade 10 is set.
The bolt 16 is tightened appropriately so that the band blade 10 does not come out of the pinch groove 11a and the tensioning function of the regulating member 17 works, and the jig is removed, and the regulating member 17 is set in a free state, and the band blade 10 is tensioned. After this, the nut 12a and bolt 16 are completely tightened and fixed. In addition, to remove the band blade 10, loosen the nut 12a and bolt 16 and remove the pinch block 1.
A gap is made between 1 and 11, and the band blade 10 is extracted from there.

The cutting tool of the present invention is attached to a well-known cutting device, and cuts a cake or the like into a constant width using band blade portions aligned parallel to each other between a pair of attachment members A and B.

The fixed structure of B is arbitrary. The band blade 10 shown in the figure is designed so that all parts thereof can be curved in the same way, but it can also be structured so that only a part of it can be curved by partial tempering or the like. It is not necessary that all of the regulating members 17 be expanded diameter spring members.

[Effect of idea]

As explained above, the cutting tool of the present invention is a cutting tool in which a cutting blade is attached to a pair of mounting members arranged in parallel with each other at an interval, and each of the mounting members is fixed in a straight line by a fastening means. It is composed of a plurality of clamping blocks that are fastened together, and the cutting blade is a long, bendable band blade. A curved end portion and one or more intermediate curved portions are formed, and the necks of these curved portions are sandwiched between the pinching grooves of the pinching blocks of each mounting member, and the portions between the pair of mounting members are parallel to each other. A pair of mounting members are installed in a meandering manner in alignment with each other, and regulating members for regulating the inner peripheral shape of each curved portion are individually installed in each of the end curved portions and each intermediate curved portion. One or more regulating members inserted into the curved part are configured as diameter-expanding spring members, and there is no need to caulk the protrusions like a conventional cutting blade, and the slit can be precisely formed by electrical discharge machining. Since it does not need to be well formed, it can be manufactured at low cost. Moreover, each diameter-expanding spring member applies tension evenly to the entire cutting blade, which has the effect of maintaining a tensioned state.
