Abstract

PURPOSE:To fit a motor box in a position set for a working space by detachably providing the motor box to an arbitrary position in front of a frame. CONSTITUTION:A motor box 20 is fitted to a frame 12 so as not to obstruct the way in the working space. For instance, since belt-passing holes 18 are provided at three places, the motor box 20 is fitted to any position out of these three places. A part of an endless belt 30 is pulled out from the belt-passing hole 18 at the central part, and it is wound aroung a motor pulley 24 through guide pulleys 26, 28. Thereby, the installation of an industrial robot 10 is completed. Then, a motor 22 is turned, and a slider 32 is moved along rails 16 with the movement of the endless belt 30.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an industrial robot for uniaxial movement.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
Pulleys are respectively provided at both left and right ends of 2, and the endless belt 130 is stretched over the pair of pulleys 114 and 115.
There is an industrial robot 100 for uniaxial movement in which a slider is provided on the endless belt 130, and the slider 132 is movable left and right along the frame 112.

In this industrial robot 100, in order to drive the slider 132, that is, the endless belt 130, a part of the endless belt 130 is pulled out forward from the left end of the frame 112, and the pulled out endless belt 13 is pulled out.
The motor 12 in which a part of 0 is provided in the motor box 120
It was hung on the second motor pulley 124. As a result, when the motor 122 is rotated, the belt 130 is driven and the slider 132 moves in the left-right direction.

[0004]

However, in this industrial robot 100, since the position of the motor box 120 is always fixed with respect to the frame 112, the dead space or the work space of the industrial robot 100 is reduced. Due to the installation conditions, this motor box 12
0 may get in the way.

In view of the above problems, the present invention provides a motor box that does not cause a problem when an industrial robot is installed.

[0006]

In the industrial robot of the present invention, pulleys are provided at both left and right end portions of a frame, an endless belt is hung on the pair of pulleys, and a slider is provided on the belt. In an industrial robot for uniaxial movement that is movable in the left-right direction along the frame, a motor box having a motor is detachably provided at an arbitrary position on the front surface of the frame, and a part of the endless belt is attached. The front end of the frame is provided so as to be pulled out forward from an arbitrary position, and a part of the pulled out endless belt is hung on a pulley of a rotation shaft of the motor inside the motor box.

[0007]

[Operation] The industrial robot having the above configuration will be described.

First, when installing an industrial robot,
Determine the position of the motor box. In this case, the motor box is mounted on the front surface of the frame so that the motor box does not get in the way. Then, a part of the endless belt is pulled out forward from the front surface of the frame to which the motor box is attached, and a part of the pulled out endless belt is hung on the pulley of the rotary shaft of the motor. As a result, when the motor is rotated, the belt is driven and the slider moves.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 10 is an industrial robot for uniaxial movement of this embodiment.

Reference numeral 12 is a frame of the industrial robot 10 and forms a rectangular parallelepiped.

Reference numerals 14 and 15 denote a pair of pulleys provided at both left and right ends inside the frame 12.

Reference numeral 16 is a rail provided in the left-right direction inside the frame 12.

Reference numeral 18 indicates the left side of the front surface of the frame 12,
It is a belt through hole provided at the center and on the right side at a required interval. The belt passage hole 18 is cut out from the upper end of the front surface of the frame 12.

Reference numeral 20 is a motor box in which a motor 22 is provided. The motor box 20 is detachably provided on the left side, the central part, and the right side of the front surface of the frame 12 with screws.

Reference numeral 24 is a motor pulley provided on the rotating shaft of the motor 22.

Reference numerals 26 and 28 are a pair of guide pulleys provided on the frame 12 side of the motor box 20.

Reference numeral 30 is an endless belt which is wound around the pulleys 14 and 15, the guide pulleys 26 and 28, and the motor pulley 24. The endless belt 30 is driven by the rotation of the motor 22.

Reference numeral 32 is a slider provided on the upper surface of the frame 12 so as to be movable in the left-right direction. The slider 32 is attached to the endless belt 30 and moves along the rail 16.

The installation state of the industrial robot 10 having the above structure will be described.

First, the motor box 20 is placed in the frame 1 so that the motor box 20 is in a position that does not interfere with the work space.
Attach to 2. For example, in the case of FIG. 2, since the belt through holes 18 are provided at three places, the motor box 20 is attached to any one of these three places (the central position in FIG. 1).

A part of the endless belt 30 is pulled out from the belt passing hole 18 in the central portion and is passed over the motor pulley 24 via the guide pulleys 26 and 28. This completes the installation of the industrial robot 10.

When the motor 22 is rotated, the slider 32
Moves along the rail 16 as the endless belt 30 moves.

With the industrial robot 10 having the above structure,
Since the motor box 12 can be installed at an arbitrary position with respect to the frame 12, the motor box 12 can be installed at a position where it does not interfere with the work space. Further, the motor box 20 is
Since it is provided outside the frame 12, the frame 12
The size in the front-back direction can be reduced.

Although the belt through holes 18 are provided at three places in the above embodiment, the present invention is not limited to this, and four or more places or two places may be provided at any place.

[0025]

As described above, according to the industrial robot of the present invention, the motor box can be mounted at any position with respect to the frame, so that the motor box can be mounted at a position corresponding to the working space.
