Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a blanket and other blanked fabrics (including fur leather, etc.)
It is referred to as "haired fabric" or "fabric". The present invention relates to a shearing device for shaving the surface, and more particularly to a shearing device for trimming long and short hairs on the surface of a fabric to produce a flat and glossy fabric.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, a large number of blade members 124a are attached to a cylindrical cylinder 12 as shown in FIG.
Rotary blades 1 spirally arranged along the outer circumference of 3
24 and a fixed blade 125 provided below the rotary blade 124 are combined, and the positional relationship between the rotary blade 124 and the fixed blade 125 and the entire shearing mechanism 102 including the rotary blade 124 and the fixed blade 125 are moved in the vertical direction. By doing
By adjusting the positional relationship with the cloth supporting member 104 of the shearing table provided below, the surface of the haired cloth W moving on the cloth supporting member 104 of the shearing table is shaved.

[0003]

As described above, in the conventional shearing device, when the surface of the haired cloth W moving on the cloth supporting member 104 of the shearing table is subjected to the shaving, the rotation of the rotary blade 124 and the fixed blade 125 is performed. By moving the entire shearing mechanism 102 in the vertical direction, the positional relationship between the shearing table provided below and the fabric supporting member 104 is adjusted, but the weight is heavy and the rotating blade 124 is moved at high speed. Rotation, for example, moving the entire shearing mechanism 102 in the vertical direction, which needs to be rotated at 1,000 rpm or more, involves extremely difficult work, and due to the structure of the apparatus, the precision of shearing on the surface of the wool fabric W is increased. It was difficult to maintain accuracy.

[0004] In particular, in order to continuously shear the surface of the long haired cloth W having a seam, a seam of the haired cloth W is detected by a sensor, and a shearing mechanism is provided based on the detection signal. Although it is necessary to move the entirety of the shearing mechanism 102 in the vertical direction instantaneously, as described above, it is extremely difficult to move the entirety of the shearing mechanism 102 in the vertical direction. It is difficult to continuously perform shaving on the surface of the fabric W, and there is a problem that the working efficiency is significantly reduced.

[0005] In the conventional shearing apparatus, the upper surface of the haired cloth W moving on the cloth supporting member 104 of the shearing table includes the rotating blade 124 and the fixed blade 1.
25, it is not possible to confirm the state of the wool fabric W in the vicinity of the shearing position. Therefore, when an abnormal situation occurs, prompt and accurate measures are taken. There is a problem that it is difficult to perform.

By the way, in view of the above-mentioned problems of the conventional shearing device, the present inventor has previously described a suction box 221 and a rotary blade 224 disposed inside the suction box 221 as shown in FIG. Proposed a shearing device in which a shearing mechanism 202 having a fixed blade 225 disposed on the outer wall surface of a suction box 221 is fixedly provided on a base 201 (Japanese Patent Publication No. 7-113188).
Reference).

However, in this shearing apparatus, the shearing table mechanism 203 is swung to adjust the positional relationship between the shearing mechanism 202 and the fabric support member 204 of the shearing table mechanism 203. , And it was difficult to always maintain high precision of the shearing on the surface of the wool fabric W.

Further, in this shearing device,
A fabric support member 204 that supports the haired fabric W in opposition to the rotary blade 224 and the fixed blade 225 of the shearing mechanism 202.
Is provided so as to be swingable by the manual lever 207. Therefore, of the problems of the conventional shearing device, the shearing of the surface of the long wool fabric W having a seam is one of the problems of the conventional shearing device. The point that it is difficult to carry out continuously is still not solved.

[0009]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional shearing device, the present invention makes it possible to easily and precisely adjust the positional relationship between the shearing mechanism and the fabric supporting member of the shearing table mechanism. It is an object of the present invention to provide a shearing device that can perform the shearing of the surface of a long continuous cloth having a seam while being able to perform the shaving continuously.

As shown in FIG. 2, a rail 13 for fixing a rail 13 slidably supporting the shearing table mechanism 3 to the upper surface thereof. An laying portion 11, a shearing mechanism fixing portion 12 for fixing the shearing mechanism 2, and a boss portion 15 for pivotally supporting a delivery roll 59 of the cloth W described later are formed.
In this case, the base 1 is formed to have a size and weight that can securely support the shearing mechanism 2 and the shearing table mechanism 3. Further, at an appropriate position in the vicinity of the rail laying portion 11 of the base 1, the movement adjusting mechanism 7 abuts and forms a fixing portion 14 a of the abutting plate 14 for positioning the shearing table mechanism 3. In addition, a boss 16 is formed on the base 1 to support another roll (not shown) that moves the fabric W while guiding the fabric W.

As shown in FIG. 3, a shearing mechanism 2 fixed to the base 1 includes a suction box 21, a rotary blade 24 disposed inside the suction box 21, and an outer wall surface of the suction box 21. And a fixed blade 25 disposed therein.
In this case, a shutter member 22 is slidably provided on the outer wall surface of the suction box 21 so as to face the fixed blade 25, and a slit 27 is formed by the shutter member 22 and the fixed blade 25 so as to form a gap 27 between the slit 27 and the opening. It is formed so that the position can be adjusted arbitrarily.
