Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing machine for transferring a work into a plurality of processing machine main bodies by an articulated robot, and more particularly to a processing machine which is downsized and can be installed in a small space. is there.

[0002]

2. Description of the Related Art Conventionally, this type of processing machine has an articulated robot, a plurality of NC machine tools, etc., and the articulated robot is configured to reciprocate through a slide mechanism installed on the floor. There is. On the other hand, the NC machine tools are arranged side by side on both sides of the articulated robot along the slide direction of the slide mechanism.

Further, in this processing machine, the articulated robot reciprocates to transfer the work into the NC machine tool, and when the machining of the work is completed in the NC machine tool, the articulated robot makes the NC machine tool. It is configured to take out the work from inside.

[0004]

However, in such a conventional processing machine, since the articulated robot reciprocates through the slide mechanism installed on the floor surface as described above, the floor surface is not Since the installation space required for the slide mechanism is obstructed and the space between the articulated robot and each NC machine tool cannot be made close, the processing machine becomes large and the processing machine can be installed only in a large space. There are problems such as.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a processing machine which can be installed in a small space.

[0006]

In order to achieve the above object, the present invention provides a slide mechanism slidably provided along a top frame installed above a floor surface, and a movable portion of the slide mechanism. An articulated robot that is suspended from the articulated robot and that grips and transfers the work in the stocker, and a plurality of processing machine bodies that are arranged on both sides of the articulated robot along the sliding direction of the movable part. It is characterized by

[0007]

According to the present invention, the articulated robot is suspended and attached to the movable portion of the slide mechanism, and the slide mechanism is slidably provided along the top plate frame installed above the floor surface. Since the installation space of the mechanism is on the top plate frame side, the space between the articulated robot and the plurality of NC machine tools can be reduced on the floor surface without being obstructed by the installation space of the slide mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a processing machine according to the present invention will be described in detail below with reference to FIGS.

In this processing machine, as shown in FIG. 1, a top plate frame 1 is installed above a floor surface 3 by a pair of columns 2a and 2b, and the bottom plate side of the top plate frame 1 has a top plate frame 1 A slide mechanism a that is slidable along is provided.

The slide mechanism a is composed of a rodless cylinder 4, and a movable portion inside the rodless cylinder 4, that is, a piston 5 (see FIG. 4).
Is provided so as to be capable of reciprocating between the pair of columns 2a.

Further, the piston 5 has a bracket 6
The articulated robot 7 is mounted in a suspended state via the, and when the piston 5 of the rodless cylinder 4 approaches the column 2a on one side, the articulated robot 7 has a two-stage work stocker. The work W is grasped and transferred from within 8.

In addition, in the vicinity of the articulated robot 7, as shown in FIG. 2 and FIG.
C machine tools 9a to 9d are provided, two NC machine tools 9a and 9b of which are located on one side of the articulated robot 7 and in the sliding direction of the piston 5 (indicated by arrow a in the figure). It is installed side by side. The other two NC machine tools 9c and 9d are located on the other side of the articulated robot 7 and are arranged side by side along the sliding direction of the piston 5 (indicated by arrow a in the figure).

At this time, since the installation space of the slide mechanism a is located on the top plate frame 1 side as described above, on the floor surface 3, the articulated robot 7 and the articulated robot 7 are not obstructed by the installation space of the slide mechanism a. Each NC machine tool 9a
The interval with ~ 9d can be made close.

The two-stage work stocker 8 is installed directly on the column 2 on one side, and the work W in the stocker 8 is appropriately supplied by an operator or the like.

Further, the articulated robot 7 can freely move within the range of the two-dot broken line (robot work area) as shown in FIGS. 1 to 3 by adjusting and controlling the angle of each joint. It is configured.

The operation of the processing machine configured as described above will be described below with reference to FIGS. 1 to 3. It should be noted that the work W is set in advance in the work stocker 8.

According to this processing machine, first, when the piston 5 of the rodless cylinder 4 moves toward the column 2a on one side and the multi-joint robot 7 comes closest to the column 2a on one side, the multi-joint is generated. The robot 7 grabs the work W from the two-stage work stocker 8 and transfers it to the NC machine tool 9a. The workpiece W transferred in this way is the NC machine tool 9a.
The first processing is performed inside.

Next, when the first machining as described above is completed, the articulated robot 7 grasps and takes out the machined work W from the NC machine tool 9a. After that, when the piston 5 of the rodless cylinder 4 moves toward the strut 2b on the other side and the articulated robot 7 reaches the front surface of the NC machine tool 9b, the articulated robot 7 moves the work W inside the NC machine tool 9b. Transfer to. Work W transferred in this way
Performs the second machining in the NC machine tool 9b.

Further, the NC machine tools 9a, 9 as described above are used.
Simultaneously with the machining in b, the same machining is performed in the other NC machine tools 9c, 9d.

By the way, the articulated robot 7 as described above is used.
Of work W by NC and NC machine tools 9a, 9b
When the work W is repeatedly processed by the process, and the work W is processed into a desired shape, the articulated robot 7 causes the work W to
Is transferred into the two-stage work stocker 8 and the work W is returned to its original position.

When all the works W in the two-stage work stocker 8 are processed, the works W are newly set in the work stocker 8 instead of the processed works.

Therefore, according to the above embodiment, since the installation space of the slide mechanism is located on the top plate frame side, the installation space of the slide mechanism is not obstructed on the floor surface, and the articulated robot and the plurality of joint robots are not interfered with. The distance from the NC machine tool can be reduced.

In the above embodiment, a total of four NC machine tools are installed on both sides of the articulated robot.
It is not limited to this number. Further, in the above embodiment, the top plate frame is installed above the floor surface by the pair of columns, but the top plate frame may be installed directly on the ceiling.

[0024]

As described above, in the processing machine according to the present invention, the articulated robot is suspended and attached to the movable portion of the slide mechanism, and the slide mechanism is mounted on the top plate frame installed above the floor surface. Since the slide mechanism is slidable along the installation space, the installation space of the slide mechanism is located on the top plate frame side. Therefore, on the floor surface, the articulated robot and the NC machine tools are not obstructed by the installation space of the slide mechanism. Can be closely spaced. As a result, the processing machine can be downsized, and the processing machine can be installed in a small space.
