Description

DETAILED DESCRIPTION OF THE INVENTION Industrial field of application: The present invention relates to a fur, in particular an expensive fur cutting machine.

Conventional technology: Mink, fox and other furs have a habit of raw tanning and are difficult to form into a desired shape when tanned, so the fur is cut into strips, and the strips are sewn together after removing the strain. Is normal.

The cutting method is performed manually or mechanically with a sharp blade such as a razor.

When cutting, it is necessary to apply a blade from the back side of the fur and take great care not to cut the hair growing on the surface.

A typical cutting machine currently used is (a) in Fig. 3.
As shown in the figures and (b), a cutting body A having a rotatable horizontal shaft in which a plurality of rotating disc blades (1) are arranged at appropriate intervals by a spacer (2), and fur to be cut (5) A large number of needles (6) for feeding the rotating disc blade (1) of the cutting body A to the horizontal cylindrical shaft (6a)
The fur carrier B, which is planted in, is the main component. The roller (4) has a function of pressing the fur (5) from above and capturing it on the fur carrier B, and the cover (3) has a function of preventing the fur cut into a band from being wrapped around the cut body A. do.

The fur to be cut (5) with the inside of the skin up is the cut body A and the carrier B.
By rotating with, it is sent between the two and the rotating disc blade
Only the skin is cut in (1). It is desirable to perform this work carefully by hand because the fur to be cut is expensive, but it goes without saying that it can be mechanized and automated very easily.

Problems to be Solved: The fur cutting machine having the shape shown in FIGS. 3 (a) and 3 (b) can be safely used for furs with relatively short hair such as mink. However, in the case of long fur such as fox fur, it is not suitable for use due to the drawbacks listed below.
There is no choice but to rely on manpower for cutting.

(A) Since the fur carrier B has a cylindrical shape, the fur cannot be held unless the large number of relatively short needles (6) are used, and the hair is easily entangled with the needle. It causes hair damage.

(B) Since the needle (6) rotates about the horizontal cylindrical axis (6a), the fur (5) and the needle (6) come close to each other before cutting is performed,
Therefore, an unfavorable phenomenon of pressing the hair against the blade (1) occurs, and the blade that cuts the skin further easily cuts the hair.

(C) The needle (6) that has passed under the blade (1) may wind up the belt-shaped fur along the cylindrical surface of the fur carrier B, and make the cutting operation impossible.

Means for Solving the Problems: In order to solve the above problems, in the present invention, the fur carrier B is a horizontal flat plate. Along with this, the needles to be implanted are made longer and the density of implantation is reduced (1 to 1.8 needles / cm ² , the conventional needle length is approximately 19
mm, about 35 mm in the present invention).

That is, the present invention provides a cutting body having a plurality of rotating disc blades, which are arranged on a rotatable horizontal shaft, concentrically with the shaft center, and vertically and at appropriate intervals, and a fur to be cut is fed to the cutting body to cut the fur. In a fur cutting machine including a carrier for discharging the band-shaped fur that has been discharged, a conventional cylindrical carrier is discharged, and the fur is attached to the lower part of the rotary disc blade attached to the horizontally held cutting body. , A horizontal flat plate-like carrier that is reciprocally movable in the horizontal direction perpendicular to the horizontal axis, in which a large number of needles are planted vertically, and the fur to be cut is placed on the carrier and held by the needles. In this state, the fur cutting machine has a structure in which the fur is cut horizontally into the fur in a state of being cut into strip-shaped fur.

Action: The fur to be cut is held by a large number of needles planted in the upper part of the carrier with the back of the skin facing upward and the hair hangs down, and enters the lower part of the cutter to be cut. When the horizontal plate-shaped carrier is used, the gap between the disc blade and the carrier is obviously less changed in the traveling direction of the carrier, as compared with the horizontal cylindrical carrier. For this reason, the gravitational force acts more conspicuously, and the bristles suspended almost downward are housed between the needles and are hardly wound around the rotating disc blade. Further, therefore, hair is hardly cut by the disc blade.

In addition, when the horizontal flat plate carrier is used, a longer needle can be used and the density of the needles (the number of needles per unit area) can be made smaller than that of the cylindrical carrier, and as a result,
The strength of the carrier is increased (commercial needle length is about 19 mm and average diameter is 1 mm, whereas the needle of this invention is about 35 mm in length and average diameter is about
It is 1.1 mm. ), Resulting in less hair pain.

Example: In FIGS. 1 and 2 (a) and (b), a plurality of disc blades (1) are concentrically arranged on a horizontal axis (1a) at appropriate intervals by a spacer (2). It is attached to form a cut body A.

The cutting body A is rotated by the driving machine (9) in the direction of the arrow to perform cutting. The carrier B has a structure in which a large number of needles (6) are planted on a horizontal flat plate (8), and the fur to be cut (5) is fixed and held by the tips of these needles (6), and a handle (10) is used. When moving from the left to the right in FIG. 1, it is cut into strips by the rotary disc blade (1) (FIG. 2 (a)). The driving machine (9) rotationally drives the rotary disc blade (1), and at that time, the rotary disc blade (1) blows a small amount of air to the left side of FIG. 1 and FIG. 2 (a). To the right to prevent curling of hair and reduce cutting of hair by the rotating disc blade. The perforated plate (7) has a large number of holes (7a) that can be loosely fitted in the needles (6) erected on a horizontal flat plate, and the carrier B is shown in FIGS. 2 (a) and 2 (b).
As shown in the figure, the fur is cut, and after the cutting is finished, the attached hair is removed by letting it escape upward at the right end of the rail (11) in FIG. be able to. (After removing the cut hair, attach it to the original position, move it to the left in FIG. 1, hold the fur to be cut, repeat the cutting work.) The cover (12) protects the rotating disc blade (1). And acts to prevent dust. (2) is the spacer of the rotating disc blade (1),
(3) is a cover of the rotary disc blade (1) for preventing the cut belt-shaped fur from being caught, (4) is a holding roller for preventing the fur to be cut from coming off the needle (6), (5) ) Is the fur to be cut.

The smaller the number of needles to be planted in the carrier B per unit area of the horizontal plate, the less damage to the fur, but the number of needles used in the present invention is about 1 to 1.8 needles / cm ² . By setting the length of the needle to about 35-40 mm, the damage to the fur can be minimized.

Effect of the Invention: In the present invention, since a horizontal flat plate is used as the fur carrier, the band-shaped fur that has been cut is not wrapped around the cut body.
It can be taken out without damaging the hair, so that the work efficiency of the cutting machine can be increased and a beautiful product can be obtained.

Further, by removing the waste hair by the hole plate that loosely fits the needle planted on the horizontal flat plate, it is possible to keep the circumference of the needle of the horizontal flat plate clean and prevent troubles due to the waste hair, Failure due to this can be prevented.
