[Structure] A guide rail 2a and a rail 1 are provided below a moving object, and a first guide portion 3, a second guide portion 4, and a third guide portion 5 are provided between the guide rail 2a and the rail 1. And a clamp means for clamping the guide rail 2a and the rail 1 and a spring 7 for connecting the first and third guide portions 3 and 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a moving device using a jack as a driving force.

[0002]

[Prior art]

 Conventionally, a moving device using a jack as a driving force is known to move a moving object on one side of expansion and contraction of the jack, and return the jack to its original state on the other side, that is, a technique of moving by a so-called worm-like insect movement. .

[0003]

[Problems to be solved by the device]

 However, in the above technique, since only one of the expansion and contraction of the jack contributes to the movement, the moving speed becomes half or less of the jack speed.

Therefore, an object of the present invention is to provide an efficient moving device that uses a jack as a driving force and has a high moving speed.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a moving device using a jack as a driving force, a guide rail and a rail for moving the moving object are provided below the moving object, and the guide rail and the rail are provided on the piston rod side of the jack. A first guide portion, a second guide portion at a cylinder end portion of the jack, and a third guide portion between the first and second guide portions are provided, and the first, second and third guide portions are provided. Clamping means for clamping the guide rail and the rail are respectively provided at the upper end and the lower end of the guide portion 3, and springs are provided for connecting the first and third guide portions.

[0006] It is preferable that the above-mentioned clamp means is configured such that the tightening jack is operated by a limit switch in accordance with expansion and contraction of the jack.

[0007]

[Action]

 In the moving device configured as described above, the rail is clamped by the clamp at the lower end of the first guide portion, and the guide rail is clamped by the clamps at the upper ends of the second and third clamps to extend the jack. Move the moving object, then clamp the moving object with the clamps at the upper ends of the first and third guide sections, and clamp the rail with the clamp section of the second guide section to move the moving object by shortening the jack. To do.

Then, if the guiderel and the rail are clamped by the upper and lower clamps of the third guide portion and all the clamps of the first and second guide portions are released, the jack can be moved by a spring force against a moving object. Since it returns to the position of and, if this operation is continued, the jack can be extended and retracted.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, a guide rail 2 a that moves integrally with the moving object 2 is provided below the moving object 2, and the guide rail 2 a includes the first guide portion 3, the second guide portion 4, and the third guide portion 4. It is movably provided on the upper part of the rail 1 through a plurality of moving devices which are basically constituted by the guide portion 5 of the cylinder 6, the cylinder 6a of the jack 6, the piston rod 6b and the spring 7.

Also referring to FIG. 2, the piston rod 6 b of the jack 6 is attached to the first guide portion 3 by the pin 8, and the cylinder 6 a is attached to the second guide portion 4 by the pin 8. There is. The first guide portion 3 and the third guide portion 5 are connected by a spring 7.

Further, the first to third guide portions 3, 4 and 5 are provided with tightening jacks 9 which are clamping means, respectively, and are connected to limit switches (not shown) which are interlocked with the jacks 6.

The operation will be described below with reference to FIG. First, the rail 1 and the guide rail 2a are clamped by the lower end A of the first guide part 3, the upper end E of the second guide part 4 and the upper end F of the third guide part 5, respectively (FIG. 3-K). When the jack 6 is extended, the upper end D of the first guide portion 3, the lower end B of the second guide portion 4 and the lower end C of the third guide portion 5 slide, the spring 7 extends, and the moving object is only d. Move (Fig. 3-L). Next, when B, F and D are clamped and the jack is contracted, the moving object moves by d (Fig. 3-M).

Then, when the upper end F and the lower end C of the second guide portion are clamped and the other clamps are opened, the force of the spring 7 extending causes the jack 6 to return to the original position with respect to the moving object ( Figure 3-N). The above operation may be repeated.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it is possible to move at approximately twice the speed compared with the conventional technology in which only one of the expansion and contraction of the jack is operated, and the work efficiency is improved. .
