A rotary plate, a support bracket reciprocally movable in parallel with the drive shaft and connected to a traverse member, and disposed between the support bracket and the rotary plate in a state of sandwiching both surfaces of the rotary plate. And a conversion means for converting the rotational movement of the rotary plate into the reciprocating movement of the support bracket.

Further, in order to achieve the second object, a drive shaft rotated by a drive means, a rotary plate fixed integrally with the drive shaft in an inclined state with respect to the drive shaft, and reciprocating in parallel with the drive shaft. A support bracket that is movably provided and is connected to the traverse member, a bracket that is integrally movable with respect to the support bracket and that is attached so that the distance from the drive shaft can be changed, and both sides of the rotary plate are held. In this state, there is provided conversion means arranged between the bracket and the rotary plate for converting the rotary motion of the rotary plate into the reciprocating motion of the support bracket.

[Operation] In the device of the present invention, the movement of the rotating plate (swash plate) that rotates integrally with the drive shaft as the drive shaft rotates is converted into reciprocating motion by the converting means, and the reciprocating motion can be performed in parallel with the drive shaft. The traverse member is reciprocated along with the reciprocating motion of the support bracket by being transmitted to the provided support bracket. In the device according to the second aspect, the distance between the conversion means and the drive shaft is changed by changing the fixing position of the bracket provided with the conversion means for converting the rotational movement of the rotary plate into the reciprocating movement of the support bracket. That is, the size of the radius of the engaging position of the converting means with respect to the rotary plate is changed to change the stroke length of its reciprocating motion, and the stroke length of the traverse member, that is, the traverse width of the traverse device is changed accordingly.

[Embodiment 1] An embodiment of the present invention will be described below with reference to FIGS. A drive shaft 2 is rotatably supported by a support box 1 provided at one end of the machine base in parallel with the longitudinal direction of the machine base, and is rotationally driven by a drive means such as a motor (not shown). A disk 3 as a rotating plate is fixed to the drive shaft 2 so as to be integrally rotatable in a state of being inclined with respect to the drive shaft 2. A pair of guide locks 4 are fixed in the support box 1 parallel to the drive shaft 2, and a support bracket 5 connected to one end of a traverse rod 6 as a traverse member is slidably supported on the guide rod 4. There is. An accommodating groove 5a extending parallel to the drive shaft 2 is formed in the support bracket 5, and the bracket 7 is slidably accommodated in the accommodating groove 5a. An adjustment bolt 8 is fixed to the bracket 7 in a state of penetrating the support bracket 5 in a state of being orthogonal to the drive shaft 2, and the bracket 7 is rotated relative to the drive shaft 2 by rotation of a nut 9 screwed to the adjustment bolt 8. Approaching,
Can be separated. The bracket 7 is formed with a pair of elongated holes 10 extending in parallel with the adjusting bolts 8, and the bolts 11 screwed to the support bracket 5 while penetrating the elongated holes 10.
Thus, the bracket 7 is fixedly fastened to the support bracket 5.

A pair of arms 12 is formed on the bracket 7 so as to extend in the direction opposite to the adjusting bolt 8 while sandwiching the disk 3. A ball is placed inside the arm 12 that faces the disk 3 across it.
A recess 14 for receiving a part of 13 is formed, and a piece 15 arranged so as to hold the disk 3 on both sides thereof is supported at a predetermined position between both arms 12 via a ball 13. The ball 13 and the piece 15 constitute conversion means for converting the rotational movement of the disc 3 into the reciprocating movement of the support bracket. Since the machining of the disk 3 is extremely simple as compared with the machining of the cylindrical cam, the manufacturing of the entire drive device becomes easier than that of the device using the conventional cam.

Next, the operation of the device configured as described above will be described.
When the drive shaft 2 rotates, the disc 3 also rotates integrally. Disk 3
Is inclined with respect to the drive shaft 2, and the piece 15 is supported by the ball 13 in a state in which it cannot revolve around the drive shaft 2, so that the piece 15 moves with the rotation of the disk 3. It reciprocates between the position shown by the chain line and the position shown by the solid line in the figure. Since the piece 15 is slidably supported on the ball 13,
The angle is freely changed according to the contact state with the disc 3, and while performing a seesaw motion around the point A, while rotating due to the difference in the distance from the center of the drive shaft 2 of the portion contacting the disc 3. Reciprocate on line L. The reciprocating motion of the piece 15 is transmitted to the bracket 7 via the ball 13, and the traverse rod 6 is also reciprocated by the support bracket 5 reciprocating integrally with the bracket 7 along the drive shaft 2.

Stroke of reciprocating traverse rod 6
Is equal to the stroke of the reciprocating motion of the bracket 7, and its value is proportional to the distance between the position where the piece 15 is arranged and the center of the drive shaft 2. This distance can be changed by changing the fixing position of the bracket 7 with respect to the support bracket 5. When changing the fixing position of the bracket 7 to the support bracket 5, first, the bolt 11 is loosened to release the tightened state of the bracket 7, and then the nut 9 is rotated. Thereby, the bracket 7 is moved in the direction orthogonal to the drive shaft 2 by being guided by the elongated hole 10 and the bolt 11, and the distance between the drive shaft 2 and the bracket 7 is changed. By tightening the bolt 11 with the bracket 7 moved to a predetermined position, the fixing position of the bracket 7 to the support bracket 5 is changed as shown in FIGS. Therefore, in the apparatus of this embodiment, the size of the stroke of the reciprocating motion of the traverse rod 6, that is, the traverse width can be easily changed by changing the fixing position of the bracket 7.

[Second Embodiment] Next, a second embodiment will be described with reference to FIG. In this embodiment, the method of supporting the ball 13 is different from that of the device of the previous embodiment, and the other structures are the same. In the device of this embodiment, an adjusting bolt 16 is screwed onto both arms 12 of the bracket 7 while extending parallel to the drive shaft 2, and a ball 13 is fixed to the tip of the adjusting bolt 16. A nut 17 for preventing the adjustment bolt 16 from loosening is screwed. In the device of this embodiment, when assembling the device, the positional interval between the two pieces 15, the ball 13 and the disc 3 can be finely adjusted by adjusting the screwing amount of the adjusting bolt 16, so that the device can be easily assembled. Become.

The present invention is not limited to the above embodiment, and for example, as shown in FIG. 6, a piece 15 having a shape obtained by cutting a part of a sphere is used, and the cut surface is in contact with the disk 3. You may assemble in the state which does. In this case, the number of parts is reduced and the assembling is simplified as compared with the above embodiment. Further, in each of the above-described embodiments, the piece 15 is supported by the bracket 7 which is attached to the support bracket 5 so as to be able to change the distance from the drive shaft, and the distance between the drive shaft 2 and the piece 15 can be changed. However, the support bracket 5 and the bracket 7 may be integrally formed so that the distance between the piece 15 and the drive shaft 2 cannot be changed. Further, a belt may be used as a traverse member instead of the traverse rod 6.

[Effects of the Invention] As described in detail above, according to the present invention, the manufacture thereof is simpler than that of the conventional device using the cylindrical cam. Further, in the device according to the second aspect, in addition to the above effect, the stroke size of the traverse member can be easily changed without changing parts by changing the distance between the drive shaft and the disposition position of the replacing means.
