Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a workpiece conveying device installed between two press machines to convey a workpiece from one press machine to the other press machine. .

Prior Art A conventional conveying device for this type of workpiece is U.S. Patent No. 3.
, 407,724, but
In the conveying device shown in this conventional example, two
A workpiece support claw is fixed directly to a belt wrapped around two pulleys, and the workpiece is placed on the workpiece support claw of this belt and moved from one press machine to another. , the posture of the workpiece could not be changed during its movement.

If you want to move a workpiece processed by one press machine to the other press machine by changing its horizontal orientation, conventionally, the workpiece is transferred by another process before or after being transferred by a transfer device. is rotating horizontally,
There was a problem that one extra processing step was required.

OBJECTS OF THE INVENTION The present invention was conceived in view of the above-mentioned problems, and it is possible to horizontally turn a workpiece while being transferred from one press machine to another, thereby making it possible to rotate the workpiece between adjacent press machines. An object of the present invention is to provide a workpiece conveyance device that can convey a workpiece while changing its posture in the horizontal direction without requiring a turning process using a special device.

Structure of the invention A string such as a timing belt is stretched in the length direction of the guide frame, and a power source capable of forward and reverse driving is connected to this string, so that the string can run freely on the guide frame. Connect the engaged traveling carrier, and connect the engaged traveling carrier to the traveling carrier.
A revolving carrier having a panel stand fixed to its upper part is rotatably provided, and a guide plate is attached to the guide frame so that the mounting orientation of the revolving carrier can be freely changed to guide the revolving carrier according to the traveling movement of the traveling carrier, so that the traveling carrier is guided. While traveling along the frame, the traveling carrier is configured so that its attitude can be horizontally turned by a guide plate.

Example Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is a frame, and this frame 1 is movable in the front and rear directions on four wheels 2. A guide tube 3 is vertically provided in the center of the frame 1, and a guide post 4 is rotatably and slidably fitted into the guide tube 3. A boss part 5 is provided on the upper part of the guide post 4. A cylinder 6 is fixed inside the guide tube 3, and a piston 6 fixed to the boss portion 5 is attached to the cylinder 6.
α is fitted. Pivot shafts 7, 7 are protruded from the front and rear outer surfaces of the boss portion 50, and the intermediate portion of the transfer unit 8 is pivotally supported on these two phase support shafts 7.7. The transfer unit 8 is composed of a support frame 9 and a guide frame 10 fixed above the support frame 9, and the two phase support shafts 7.7 are connected to the support frame 9. Pulleys 11α are provided at both ends of the guide frame 10,
IIA is supported, and timing belt 1 is attached to these.
2 is the wrapping. One pulley 11α has a reducer 1
A motor 14 is connected via 3. This motor 14
can be freely switched between forward and reverse rotation.

I5 is a bearing.

Reference numeral 16 denotes a running carrier fixed to the timing belt 12, and this running carrier 16 is engaged with the guide frame 10 through rollers 17 so as to be able to run freely. Reference numeral 18 denotes a rotating carrier mounted on the upper side of this traveling carrier 16 so as to be able to rotate freely, and a panel stand 1 is mounted on the upper part of this rotating carrier I8.
9 is fixed. The swing carrier I8 has a swing lever 2.
0 is provided, and this pivot lever 20 is connected to a roller unit 22 via a link 21. Reference numeral 23 denotes a guide plate for guiding this roller unit 22, and this guide plate 23 is attached to the upper surface of the guide frame 10 so that its attachment orientation can be changed freely.

The conveyance device having the above configuration is installed between two press machines, and its position in the front and back direction is adjusted by moving the frame 1 with wheels 2.

By rotating the timing belt 12 in the forward and reverse directions, the traveling carrier 16 is reciprocated along the guide frame 10 of the transfer unit 8, and the panel 24 processed by one press machine is attached to the panel provided above the traveling carrier 16. It is placed on the stand 19-H and transported horizontally to the other press machine [FIG. 5(A)].

At this time, the transfer unit 8 is tilted about the pivot shaft 7.7, so that it can be transported with a head difference [FIG. 5(B)].

(C)]. Furthermore, by attaching the guide plate 23 with an inclination in the front-rear direction, the rotating carrier 18 is rotated by a predetermined angle, for example, 90 degrees, while the traveling carrier 16 is moving, and the panel 24 is conveyed while being rotated by 90 degrees.
Figure 5 (E)]. Further, by rotating the transfer unit 8 in the horizontal direction and traveling on the traveling carrier 16 while rotating the rotating carrier 18 according to the rotation angle or by an angle, the panel 24 is conveyed in a horizontally offset manner [FIG. 5] (D)].

The height of the transfer unit 8 is adjusted by supplying hydraulic pressure to the cylinder 6.

The tilting and turning movements of the transfer unit 8 may be performed manually by an operator, but a power source capable of fine control such as a servo motor may also be used. After tilting and turning, the transfer unit 8 is held and held by a locking mechanism. Although the frame 1 is movable in the front and rear directions, it is fixed to the floor using locate pins or the like during work.

Effects of the Invention Since the present invention is as described above, by installing the workpiece conveyance device having the above structure between the press machines, the workpiece such as a panel processed by one press machine can be simply fixed horizontally. In addition to feeding, the workpiece can be rotated horizontally while being transferred from one press machine to the other, and the workpiece can be moved between press machines that come into instant contact without the need for a turning process using special equipment. The conveyance process can be simplified because the conveyance can be carried out while changing the posture in the horizontal direction.
