Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pedestal for an industrial robot, and particularly to a pedestal for an industrial robot that is easy to transport and install.

(Prior Art) Industrial robots have recently come to be used for assembling various industrial equipment such as automobile manufacturing.

An example of the structure of an industrial robot is a θ-axis rotatably mounted on a base fixed to the floor of a factory, and a swingable W attached to the θ-axis.
A swingable U-axis installed at the tip of the W-axis, U
It consists of a wrist attached to the tip of the shaft.

By the way, such a robot body is manufactured in a factory, and if it passes inspection, each arm of the robot is folded to a predetermined position and the robot body is packaged in a predetermined manner, leaving the base of the robot body intact. After that, the hook of the chain block is engaged with the hanging part provided at the base of the robot body, the robot body is lifted by the chain block, and the packaging wooden box is placed on the bottom plate of the forklift. By housing the robot in a wooden box, the entire robot is packed. Thereafter, a forklift lifts the robot body together with the packaging wooden box, and the robot is shipped from the factory.

After the robot body packed and transported in this manner arrives at the site where it is to be installed, it is unpacked and further transported to the installation site by a transport means such as a chain block. Then, the robot body is fixed to the floor by inserting a mounting bolt, etc., which has been set up on the floor in advance, into the hole of the installation flange that is formed protruding from the side of the lower part of the robot body, and securing it with a nut. .

FIG. 3 is an explanatory diagram of an example of the base of a conventional robot. An installation flange 12 is provided at the bottom of the base 11 and extends laterally, and an eye bolt 13 for hanging from a chain block or the like is provided at the top of the base 11 to protrude. Therefore, when transporting the robot, the chain block hook is hooked onto the eye bolt 13 and lifted onto the transfer device as described above, and the robot is transported, and when installed, the robot is mounted using the installation flange 12 that protrudes further from the base of the robot. It is fixed to the floor with bolts.

(Problems to be solved by the invention) For this reason, transportation is time-consuming, and the installation location includes the floor area of the installation flange shown by the dotted line in Figure 3. There were also problems with work safety due to the protrusion of eye bolts and installation flanges.

In other words, the pedestal that forms the base of the conventional robot as described above protrudes laterally as an installation flange that protrudes from the side of the lower part of the robot body, which unnecessarily increases the bottom area of the packaging wooden box. It has its drawbacks. In addition, in a robot manufacturing factory, for example, after assembly is completed, transportation to an inspection site and from the inspection site to a packaging site is carried out by pulling the hook of the chain block onto the hanging part provided at the base of the robot body, as described above. However, there is also the problem that complicated transportation methods such as transportation using a hoist must be used.

The present invention is intended to improve the above-mentioned drawbacks of the conventional technology.The purpose of this invention is to reduce the bottom area of the packaging wooden box as much as possible when packaging robots, and also to eliminate the need for two claws, such as those used in forklifts. To provide a robot pedestal that can be easily transported by a holding transfer device without using a bottom plate for a forklift.

(Means for Solving the Problems) According to the present invention, in a robot pedestal that is used by being fixed to an installation surface with bolts, there is a base portion that is integrally assembled as a pedestal at the bottom of the robot, and a side surface of the base portion. The present invention is characterized by comprising a horizontal groove-shaped recess formed on both sides into which a fork of a forklift is inserted when transporting the robot, and a bolt insertion hole for fixing the robot that penetrates from the recess to the installation surface of the robot. A robot pedestal is provided.

(Function) The pedestal of the present invention has a horizontal groove-like recess into which the fork of a forklift is inserted into the base itself, which is assembled integrally at the bottom of the robot body. In addition, a bolt insertion hole for mounting the robot is provided that penetrates from the horizontal groove-shaped recess into the installation surface, so by using the bolt insertion hole, it can be used in a narrow space without lateral overhang. The robot can be fixed with the mounting bolt.

(Example) Next, an example of the present invention will be described in detail using the drawings.

FIG. 1 is a perspective view showing the overall configuration of a robot according to the present invention that is easy to transport and install. In FIG. 1, reference numeral 1 denotes a θ-axis fixed part of the robot fixed to the floor surface, and a θ-axis movable part 2 that can rotate within a predetermined rotation range is mounted on the upper part.
A W-axis 3 that can swing within a predetermined rotation angle is attached to the θ-axis movable section 2, and a U-axis 4 that can swing within a predetermined rotation angle is provided at the tip of the W-axis 3. Furthermore, a wrist 5 is provided at the tip of the U-shaft 4.

In addition, the lower part of the θ-axis fixing part 1 is a base 6 that becomes a pedestal.
A horizontal groove-shaped recess 61 is carved on both sides of the base 6 into which a fork of a forklift can be inserted from the front and rear directions. The flange portion 62 at the bottom of the recess 61 has a bolt insertion hole 6 for fixing the robot that penetrates from the recess 61 to the installation surface.
3 are provided in plural numbers with a predetermined diameter. This bolt insertion hole 63 for fixing the robot does not protrude laterally from the bottom of the base like the conventional installation flange 12 shown in FIG. Configured to be fixed.

FIG. 2 is an explanatory diagram of the robot of this embodiment seen from the front.

When transporting within a manufacturing plant, after inserting a fork 7 such as a forklift into the recess 61 provided in the base 6, it can be easily lifted from the floor and moved to a desired location within an inspection site, for example. It can be done.

Also, at the installation site, the fork of the transfer device is used to transport the device using the upper recess 61, and then the fork is pulled out, and the mounting bolt is inserted into the bolt insertion hole 63 provided in the flange portion 62, and the base 6 is attached to the floor. Fix it and install the robot.

Therefore, transportation does not require much effort, and the third
There is no need for an installation location that includes the floor area of the installation flange as shown by the dotted line in the figure. Moreover, there are no eye bolts or installation flanges protruding from the base.
It is also superior in terms of safety during transportation and installation work.

(Effect of the invention) According to the robot pedestal of the invention, a recess into which the fork of a forklift can be inserted is provided at the base of the lower part of the robot body, so there is no need to lift the robot using an eye bolt or the like when transporting the robot. It can be easily transported to a predetermined location.

In addition, the installation flange that protrudes laterally as in the past is eliminated, and the bolt insertion hole is provided on the bottom surface of the recess, so there is no lateral protrusion.
Installation is possible in a narrow floor space.

Furthermore, since the floor area of the wooden box for packaging the robot is reduced, it is possible to reduce the amount of packaging materials and transportation costs.

Furthermore, since there are fewer protrusions at the base of the robot than in the past, there is also the advantage that work safety is improved.
