Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade of a ball remover for removing balls such as sweaters, socks, and blankets.

2. Description of the Related Art Conventionally, the blade of this type of pill remover has an inner blade whose rotation axis direction is substantially perpendicular to the cloth surface on which the pill is taken, and an outer blade which forms a part of a sphere. It was Further, the inner blade was always in contact with the outer blade and rotated.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional configuration, when a pill removing device is moved on the cloth and the pills are removed, the width of the pills is determined by the diameter of the outer blade around the rotation axis. When it is attempted to increase the ball take-out width, it is necessary to increase the diameter of the outer cutter, which causes the entire body to become large. Further, the inner blade is always in contact with the outer blade and rotates, so that the blade has a short life.

Means for Solving the Problem In order to solve this problem, the blade of the pill remover of the present invention has a drive unit and a shaft rotated by the drive unit so as to be in a state substantially parallel to a cloth ground for taking pills. An inner blade that is disposed and attached long in the direction of the rotation axis, an outer blade that is located outside the inner blade and has a pill introduction portion, the drive unit, and the inner blade are built-in.
And consisting of a body that holds a part of the outer blade in a form exposed to the outside of the body, the outer blade is arranged in the body by utilizing the elasticity of the outer blade itself or through another elastic body, At this time, the inner blade and the outer blade have a gap, and the outer blade and the inner blade are in contact with each other only when removing pills.

Working With this configuration, the pill removal width can be widened and the blade life can be extended without enlarging the body of the pill removal device.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, 1 is a main body, 2 is a drive unit disposed inside the main body 1, and 3 is a rotary shaft that rotates by the rotation of the drive unit 2, to which an inner blade 4 extending in the direction of the rotary shaft is fixed. 5 is an outer blade located outside 4 of the inner blade and is a pill introducing hole 5a.
And is held outside the main body 1 in a partially exposed form. Further, as shown in FIG. 2, the outer blade 5 and the inner blade 4 normally maintain a clearance 6 between them. FIG. 3 shows a state of removing pills, where 7 is a cloth and 7a is a pill. Fig. 4 shows outer blade 5
The spring 8 is arranged at the end of the convex portion 1a provided inside the main body 1.
This is an example in which the clearance 6 is maintained by combining the above and the hole 5b provided in the outer blade 5.

Next, the operation will be described. The rotation of the drive unit 2 is transmitted to the rotary shaft 3, and the rotary shaft 3 rotates together with the inner blade 4. At that time, there is a gap 6 between the inner blade 4 and the outer blade 5, and the outer blade and the inner blade are not in contact with each other. When performing the pill removal operation, the outer blade 5 exposed from the main body 1 is brought close to the fabric 7, and the outer blade 5 is pressed against the fabric 7 so that the inner blade 4 comes into contact with the outer blade 5 and, at that time, is removed from the pill introduction hole 5a. The pills 7a that have entered the inside of the blade 5 are cut. In this state, the main body 1 is moved in the direction orthogonal to the rotation axis direction. The cut pills are collected in a predetermined storage unit (not shown). When the outer blade 5 and the cloth 7 are separated from each other, the gap 6 is formed by the elasticity of the outer blade 5 itself or the spring 8.

EFFECTS OF THE INVENTION As described above, according to the present invention, the size of the main body is increased by lengthening the cutting edge portion in the rotational axis direction within a structurally and functionally permissible range and moving the main body in the direction orthogonal to the rotational axis direction. The pilling width can be increased without making the size larger than necessary. Also, by arranging the outer blade on the main body via the elasticity of the outer blade itself or another elastic member, it is possible to reliably maintain the gap between the inner blade and the outer blade except during the pill removal operation. It is to improve the life.
