0002

2. Description of the Related Art A conventional slide unit of this type has a structure as shown in FIGS. 3 and 4, as shown in, for example, Japanese Patent Application Laid-Open No. 58-114886. In FIG. 3, 1 is a substrate, 2 is a fixed block fastened to the substrate 1, and 3 is a fixed block fastened to the substrate 1 as well. 4 is a block that slides in the axial direction, and 5 is a slide shaft, two of which are arranged parallel to the moving direction, and one end is fastened to the fixed block 2 and the other end is fastened to the fixed block 3. Reference numeral 6 denotes a stopper for regulating the moving position of the block 4, and 7 a cover made of a steel plate, which is designed in consideration of the safety and aesthetics of the entire apparatus.

In FIG. 4, 8 is a detector mounting member, 9 is a photoelectric detector for detecting a stop position, and 10 is a member to be detected.

[0004] The operation of the slide unit configured as described above will be explained below.

The movement position of the block 4 is regulated by a stopper 6, which is guided by the slide shaft 5 and can be set arbitrarily. Further, a detector 9 that detects the moving position of the block 4 also moves according to the position of the stopper 6.

[0006]

[Problems to be Solved by the Invention] However, in the structure in which the base plate 1 is used as the main body member as described above, the slide shaft 5 is required to mount the stopper 6 that arbitrarily changes the stroke position of the block 4. A cover for protecting the mounting member 8 and the detector 9 is also indispensable for mounting the detector 9, which complicates the mechanism itself and causes an increase in cost and an obstacle to miniaturization.

[0007]Furthermore, the installation of this device is limited by the position of the mounting tap, making it extremely inconvenient for production equipment compatible with FMS, which requires flexibility in installation mode. Was.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a slide unit that can be made compact and simple as a whole, is easy to use, and is low in cost.

[0009]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the slide unit of the present invention has a main body having a U-shaped cross section. a moving body that moves in a direction perpendicular to the moving body, a bearing that guides the movement of the moving body, a driving means that moves the moving body along the bearing, and a stop member that restricts the range of movement of the moving body. The inner wall surface of the main body has a long groove for attaching a stop member, which is provided in parallel to the moving direction of the movable body, in order to attach the stop member, and the outer wall surface of the main body has a long groove for attaching the stop member. a detector for detecting the position of the main body, and a long groove for mounting the detector provided parallel to the moving direction of the moving body for passing the wires of the detector, and a long groove for installing the detector for installing the main body. It is characterized by having a plurality of main body installation long grooves provided parallel to the direction of movement.

0010

[Function] With the above configuration, the main body is unified and the number of parts is reduced, and the wiring process for the detector can be simplified, making the entire device more compact and lower cost. By using the long groove for installing the stop member on the inner wall of the main body, the position of the stop member can be set flexibly and easily.By using the long groove for installing the main body on the outer wall of the main body, Restrictions on how the main body can be installed can be relaxed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 11 is a main body having a U-shaped cross section, 12 is a movable body that moves inside the main body 11 in a direction perpendicular to the U-shaped cross section of the main body 11, and 13 is a moving body attached to the main body 11. , a bearing that guides the movement of the moving body 12;
14 is a rodless cylinder as a driving means for moving the movable body 12 along the bearing 13; 15 is a detected magnet for detecting the position of the block 12; 16 is a detector with a T-shaped cross section for detecting the detected magnet 15. , 17 is a translucent black acrylic cover that protects the detector 16 or makes the lamp display clearer during detection, and 18 is a steel plate cover.

In FIG. 2, reference numeral 19 designates a stop member for arbitrarily setting the range of motion of the movable body 12, 20 a plate attached to the end face of the main body 11, and 21 also a plate. 22 is a long groove for attaching a stop member. 23 is a long groove for mounting a detector, and a long groove extending portion 23a is provided in a direction perpendicular to the longitudinal direction of the long groove. 24, 25, 26
, 27 are long grooves for installing the main body, each of which is provided parallel to the moving direction of the movable body 12.

The operation of the slide unit constructed as described above will be explained below with reference to FIGS. 1 and 2.

The moving body 12 air-driven by the rodless cylinder 14 is linearly driven by the bearing 13 inside the main body 11 in a direction perpendicular to the U-shaped cross section of the main body 11. Its range of motion is regulated by the stop member 19, and its position is determined by the long groove 2 for attaching the stop member.
2 can be set arbitrarily. Further, the stop position of the movable body 12 is detected by a detector 16 that detects the position of a detected magnet 15 provided on the movable body 12, and is displayed by a lamp through a cover 17. The position of the detector 16 is also determined by the stop member 19.
Similarly, it is freely movable in the longitudinal direction of the long groove 23 for mounting the detector. Further, the wiring of the detector 16 can be routed through the long groove extending portion 23a provided in the long groove 23 for mounting the detector, thereby simplifying the wiring process.

Furthermore, long grooves 24, 25, 26 for installing the main body are provided.
, 27 are provided on each surface of the outer wall of the main body 11,
This slide unit has a large degree of freedom in mounting, and the mounting bracket can be simplified.

As described above, according to this embodiment, the main body has a U-shaped cross section, and the main body is provided with a stop member, a detector, a long groove for attaching these to the main body, and a plurality of long grooves for attaching the main body. As a result, the number of parts can be reduced, and the entire device can be made more compact and simple, including the simplification of the wiring process for the detector, and an easy-to-use, low-cost slide unit can be realized.

Further, the translucent black acrylic cover 17 protects the detector 16 from dirt and dust, and at the same time has the effect of making the red lamp display clearer.

[0019]

Effects of the Invention As described above, the present invention attaches each member to the wall surface of a main body having a U-shaped cross section, and also connects the long groove for passing the detector wiring and the long groove for installing the main body in the direction of movement of the moving body. By providing them in parallel, the entire device can be made more compact, the wiring process can be simplified, and costs can be reduced, and the degree of freedom in installing the main body can be increased, making it possible to use the device as an FMS compatible device.
