DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly for removing pills generated on the surface of a woven fabric while using and wearing the woven fabric, and relates to a pill removing device capable of cleaning and arranging the woven fabric surface. .

[Prior art]

Fabrics such as woven fabrics used for clothes and interiors are
A pill is generated on the surface due to friction or scratching during use. In order to significantly impair the appearance of the pill product and reduce the service life, pill removal and a reciprocating blade method using a rotary blade method have been conventionally proposed. Due to the difference and the speed difference of the inner blade, pill removal in reciprocating operation was likely to be uneven, and there was a disadvantage that the outer diameter was increased when trying to increase the working width. For this reason, there is also a reciprocating blade system, but there is a drawback that a powerful suction is required without dragging the pill into the blade hole with a movable blade. Therefore, the present inventor has considered a pill removing device having an outer blade curved in a U-shape with a rotary blade and having a large working width evenly moved by moving in a lateral direction.

[Problems to be solved by the invention]

However, since the inner blade provided on the outer blade curved in a U-shape with a rotary blade is formed in the same size, if the blade hole is formed large in order to remove a large pill, a large blade hole on the opposite side is formed. There were cases where pills came out of the fabric or the dough was cut on the lower surface. Further, when the blade hole is made small, there is a disadvantage that a large pill cannot be obtained. The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a pill removing device that can remove large pills, does not scatter pills, and does not damage the fabric. It is in.

The provided cover plate 61 is detachably attached to the rear opening. When the hair ball storage case 6 is attached to the main body 1 such that the lower portion is fitted into the upper surface recess of the mounting base 12, an elongated hole 63 is formed in the communication port 16 vertically penetrating the mounting base 12. In addition, the cover plate 61 faces the air inlet 15 which is open at the front of the portion of the main body 1 where the fan 41 is accommodated. Next, the inner cutter block 2 will be described. The inner blade block 2 includes an inner blade 20 configured by mounting a plurality of blades 21 on a base 23, a mounting plate 27 for mounting the inner blade 20 to the outer blade block 3, and a base 23. And a rotating shaft 22 that penetrates through. The base 23 has flanges at both ends as shown in FIG.

And the outer blade 30 of the present invention mounted on the frame 31. The outer blade 30 is provided as a thin metal plate having a number of blade holes 32 formed therein.
As shown in FIG. 5, these blade holes 32 have a large opening area at one end, and the other end and the central portion (the outer blade)
The opening area of the blade hole 32 at the top (when the 30 is curved) is made small, and a small blade hole having a smaller opening than the other end is formed at the center. That is,
In FIG. 5, the blade hole 32a located at one end is larger than the other end and the blade holes 32b and 32c at the center, and the blade hole 3a at the center is larger.
2c is set smaller than the blade hole 32b at the other end. In addition,
The peripheral blade hole 32d is for facilitating bending of the outer blade 30. Further, the rows of the blade holes 32 are configured to have an inclination indicated by θ in the figure. The outer blade 30 has a plurality of engagement holes 33 on both side ends, and a plurality of locking projections 35 formed on both inner surfaces of the frame 31 are locked in the engagement holes 33. As a result, as shown in FIG. 2, the outer blade 30 is attached to the lower surface of the frame 31 in a state of being curved downward. At this time, since the size of the engagement hole 33 is larger than that of the locking projection 35, the outer cutter 30 has its own blade within a range where the engagement between the engagement hole 33 and the locking projection 35 is allowed. It is in a state of projecting downward by elasticity. The inner cutter block 2 is mounted in the outer cutter block 3 and is attached to the main body 1 together with the outer cutter block 3.
Attachment of the inner cutter block 2 to the outer cutter block 3 is performed by fitting portions 38, 38 formed on both end pieces of the outer cutter block 3,
This is performed by inserting the mounting pieces 28, 28 on the mounting plate 27 of the inner cutter block 2. As shown in FIG. 4 (c), the fitting portion 38 has a ridge 39 on its inner surface, and the mounting piece 28 has a concave on its outer surface which engages with the ridge 39 as shown in FIG. 4 (b). A groove 29 is provided. The outer blade block 3 is attached to the main body 1 by using grooves formed on both lower sides of the mounting base 12 of the housing 10 of the main body 1.
17 and 17, ribs 37 provided on the upper part of the inner surface on both sides of the frame 31
Is performed by engaging. The outer cutter block 3 is mounted by sliding from the distal end surface of the main body 1. At this time, the rotation shaft 22 of the inner cutter block 2 is mounted.
Is formed by inserting a deformed cross section of one end protruding from the end face of the outer cutter block 3 into a square hole formed on one surface of the pulley 43 to connect the pulley 43 with the rotary shaft 22, that is, the inner cutter 20. And the motor 4 are connected. Pulley 43 and rotating shaft
The connection with 22 is made in these axial directions. When the outer cutter block 3 and the inner cutter block 2 are attached to the main body 1 in this manner, the inner cutter 20 becomes as shown in FIG.
Outer blade 30 and frame 31 in outer blade block 3, mounting base 1
2. Then, the periphery is surrounded by the mounting plate 27. If the motor 4 is rotated, the inner blade 20 also rotates about the rotation shaft 22. Here, when the outer cutter block 3 and the inner cutter block 2 are attached to the main body, the outer cutter block 3 and the inner cutter block 2 are attached such that a large blade hole 32a on one side of the curved outer cutter 30 on the front side in the rotation direction of the inner cutter 20 is located. Each blade 21 of the inner cutter 20 moves in the outer peripheral direction along the slit 26 by centrifugal force generated by rotation about the rotation shaft 22. A spring may be arranged between the base 23 and the blade 21, and the blade 21 may be urged to the outer peripheral side by the spring. As shown in FIG. 8, the hair ball H generated on the fabric S is cut while holding the grip portion 11 of the main body 1 with one hand and pressing the fabric S with the other hand. The beading device is moved along the fabric S. At this time, the direction of movement of the pill remover and the direction of rotation of the inner cutter 20 are in the relationship shown in FIG. 7, and a larger pill H is introduced into the inside through the blade hole 32 having a larger opening area of the outer cutter 30. The inner blade 20 is pulled downward and cut. The small pills H are introduced into the inside through a small hole 32 having a small opening area at the center of the outer blade 30, and are cut by the inner blade 20 slidingly contacting the inner surface of this portion. At this time, the down-cut side (that is, the inner blade of the curved outer blade 30)
The pill cut at 20 rotation direction front side moves in the direction of the arrow of rotation, but a small blade at the up-cut side of the bottom surface and the other side (that is, the inner blade 20 of the curved outer blade 30 rearward in the rotation direction). Since the hole 32 is formed, the hair ball does not jump out of the blade hole, and is fed into the hair ball storage case 6 through the communication port 16 and the elongated hole 63. Further, since only some of the blade holes 32 are large, the suction effect of the fan 41 is improved, and the hair balls H can be easily introduced into the blade holes 32 even on the side of the blade hole 32 having a large opening. Also, as shown in FIG. 6, when operated in the opposite direction, the pill is easy to remove because the blade hole 32 is small. At the center of the outer blade 30 which comes into contact with the fabric S, a blade hole 32 having the smallest opening area is provided.
Since there is only one, the fabric S is not cut. Further, since the row of the blade holes 32 has the inclination of θ as described above, a large number of hair balls H are hardly cut at the same time, and thus the cutting load is small. Furthermore, the blade 21 of the inner blade 20
Is moved to the outer peripheral side by centrifugal force, so that when a thread or the like is wound, the blade 21 easily retreats to the rotation center side. Then, the cut hairball H is moved from the communication port 16 of the mounting base 12 formed in the tangential direction of the rotation locus of the inner blade 20 by the centrifugal force caused by the rotation of the inner blade 20 and the suction force by the fan 41. It is fed into the hair ball storage case 6 through the long hole 63.
The communication port 16 and the long hole 63 have a length substantially equal to the length of the inner blade 20 in the longitudinal direction. The exhaust of the fan 41 is performed from the exhaust port 14. The pills H accumulated in the pill storage case 6 are disposed of by removing the pill storage case 6 from the main body 1 and removing the cover case 62. The hair balls H remaining inside the outer cutter block 3 are cleaned by removing the outer cutter block 3 from the main body 1. By the way, it is conceivable that the up-cut side blade hole 32 is a large blade hole. However, if the up-cut side blade hole 32 is a large blade hole, as shown in FIG. The pillow H introduced into the hole is pushed out of the blade hole 32 until it is cut off by the blade 21 at the upper end portion of the blade hole 32, so that the hair ball H is not preferable. On the other hand, when the down-cut side blade hole 32 is a large blade hole as in the present invention, the hair ball H introduced into the large blade hole 32 is bladed at the lower end of the blade hole 32 as shown in FIG. twenty one
It is easy to scissors.

【The invention's effect】

As described above, in the present invention, a rotary inner blade in which a plurality of blades are arranged in the circumferential direction, and a blade hole for introducing pills is provided, and is curved along the inner blade to cooperate with the inner blade. In a pill removing device provided with an outer blade for cutting a pill, a blade hole larger than a blade hole provided on the top and the other side is formed on one side of the curved outer blade on the front side in the rotation direction of the inner blade. Because of this, large pills can be easily removed with a large blade hole on the down cut side, and only a part of the blade hole is a large blade hole, so it is possible to introduce a pill into the blade hole with little suction. The pill can be removed quickly, and the pillow can be removed on the up-cut side without damaging the fabric since the blade hole at the top (that is, the center) is small.
In addition, by making the top hole smaller than the hole on the other side of the outer blade, when the outer blade comes into contact with the fabric, it is difficult for the cloth to enter from the top hole of the outer blade and the cloth is cut. Can be prevented.
