Description

[Detailed description of the invention] [Industrial application field] This invention relates to a panel reversing device for reversing panels to be transported in press molding equipment, etc., and enables high-speed operation of the panel transport device between upstream and downstream sides. This is to prevent mutual interference.

[Prior Art] When processing panels, it is often necessary to process from one direction suitable for processing.

For example, if a panel is processed using a drawing press to form a downwardly convex shape, and then press forming is performed, the downwardly convex panel must be reversed to form an upwardly convex shape. First, a panel reversing device has been used conventionally.

Conventionally used panel reversing devices include:
There are various types, but the two main types used are swing arm type and shuttle feeder type.

The swing arm type panel reversing device 1 has a third
As shown in the figure, it is equipped with a reversing arm 3 that protrudes upward from the swing shaft 2, and is used to move each panel P between the drawing position A and the next press position B. The panel conveyor device 4 and 5 is installed in the middle of two panel conveyors 4 and 5 installed to convey the panel P, and is designed to invert the panel P and send it to the next process.

Then, the reversal of the panel P accompanying drawing and pressing is performed as follows.

In case a in the figure in which the panel reversing device 1 is in a standby state in the continuous processing state, drawing processing is performed at the drawing processing position A, and the panel conveying device 4 for drawing processing is placed on the panel reversing device 1 side. Completed panel P-
1, and in the panel conveyance device 5 for press working,
Panel P-3 for press processing is being mounted on the press machine which is stopped at press processing position B, and panel P-2 which has been inverted is placed at panel reversal position C for press processing. It has become a state.

From this state, as shown in b in the figure, when each of the panel transport devices 4 and 5 moves by half of its moving distance, the reversing arm 3 of the panel reversing device 1
It rotates 90 degrees to the drawing press side, becomes horizontal, and receives the panel P-1 from the panel reversal position C.

As shown in c in the figure, when each of the panel conveyance devices 4 and 5 is on the drawing press side and the panel reversing device side opposite to a, the drawing machine places the drawn panel on the panel conveyance device 4. P-0 is sent out, and press processing is performed in the press processing machine. At the same time, the panel conveyance device 5 on the press side receives the panel P-2 that has been inverted from the panel inversion position C.

Thereafter, as shown in d in the figure, when each of the panel conveyance devices 4 and 5 moves in the opposite direction by half of its movement distance, the panel reversing device 1 reverses the panel P-1 to the panel reversing position C. It will be kept.

Furthermore, when the respective panel conveyance devices 4 and 5 move to the state e in the figure, the panel reversing device 1
The reversing arm 3 returns to the vertical state and enters a standby state, and the panel P advances to the respective positions A, B, and C.

Therefore, by repeating similar operations, the panel P is conveyed and the panel P is reversed.

[Problem to be solved by the invention] However, in such a swing arm type panel reversing device 1, the reversing arm 3 must swing 360 degrees in order to perform the reversing operation of one panel P.
There is a problem in that the time required for reversing becomes long and it is not possible to increase the speed of drawing or pressing.

Although not shown, even in a shuttle feeder type panel reversing device, a single panel cannot be reversed unless the shuttle moves 360 degrees.
Similarly, there is a problem that the processing speed cannot be increased.

Furthermore, with swing arm type panel reversing devices, when the reversing arm is in a horizontal state, each transport device has only moved half of its travel stroke, so there is a problem in that interference between these devices must be prevented. .

Similarly, in a shuttle feeder-type panel reversing device, there is a problem in that the conveying device and the panel reversing device in a standby state may interfere with each other, and the respective processing positions must be installed apart from each other.

This invention was made in view of the problems of the prior art, and aims to provide a panel reversing device that can reverse a panel with a small rotation angle and does not cause interference in a standby state.

[Means for Solving the Problems] In order to solve the problems of the above-mentioned prior art, the panel reversing device of this invention is installed between two panel conveying devices that approach and separate from each other within the same plane. In a panel reversing device that inverts and delivers a panel to be transported from one panel transport device to another panel transport device in an approaching state, the leading end is located at a transport position in an approaching state between the two panel transport devices. A reversing arm, in which a reversing part protrudes from both sides of a rotation axis, is provided so as to be able to rotate about a horizontal axis in a transport plane, and the reversing part of the reversing arm is set at a standby position that is perpendicular to a transfer position of the transport device. It is characterized by being provided so that it can be stopped at any time.

[Function] According to this panel reversing device, a plate-shaped reversing arm is used in which reversing parts are formed on both sides of the rotation axis, and is kept in a vertical position. In addition to being able to invert a single panel, the plate-shaped inverting arm is placed vertically in a standby state, so the conveying devices can be installed close to each other and interference with each other can be prevented.

[Example] Hereinafter, an example of this invention will be described in detail based on the drawings.

FIGS. 1 and 2 are a schematic structural diagram and an explanatory diagram of the reversing operation of an embodiment of the panel reversing device of this invention.

This panel reversing device 10 is installed, for example, between a drawing position A and a press working position B, and includes two panel conveying devices that carry a drawn panel P or a panel P for pressing (after drawing). The panel transport devices 4 and 5 are arranged between the panel transport devices 4 and 5 so as to move toward and away from each other.

First, these panel conveyance devices 4 and 5 have U-shaped support members 4a and 5 that are open on the inside in the direction of movement.
fluid pressure cylinders 4b, 5b are connected to the base end portions of these support members 4a, 5a so as to be able to reciprocate in the transport direction. and,
A pair of gripping arms 4c and 5c are provided inside the support members 4a and 5a, facing each other, and are adapted to be gripped by fluid cylinders 4d and 5d, respectively.

Next, the panel reversing device 10 moves to the drawing position A.
The panel P carried by the panel transport device 4 and placed in the pre-inversion position D is received from this pre-inversion position D, inverted, and the panel P with the front and back reversed is placed in the panel inversion position C on the press forming side. It is a device that does

In this panel reversing device 10, the reversing arm 11
U-shaped inverted portions 12 and 13 are formed on both sides of the holder so that both ends thereof are open. A pivot shaft 14 is provided at the center of the reversing arm 11, and the pivot shaft 14 is installed horizontally at right angles to the transport direction so that the reversing arm 11 can rotate with the reversing sections 12 and 13 located on both sides. A drive mechanism is provided to enable rotation.

The length of the reversing arm 11 is such that when the reversing arm 11 is turned into a horizontal state, each of the reversing parts 12 and 13 can grip the panel P at the pre-reversing position D or the panel reversing position C.

Each of the reversing parts 12 and 13 is provided with gripping arms 15 and 16 facing each other, and is adapted to perform an opening/closing gripping operation using fluid pressure cylinders 17 and 18.

A reversing operation by the panel reversing device 10 configured as described above will be explained.

First, in the continuous processing state, the second panel represents the case where the panels P processed at the drawing processing position A and the press processing position B are taken out and sent to the next process.
In the case of Figure a, each panel conveyance device 4, 5 has moved to a position away from the panel reversing device 10,
The panel conveying device 4 receives the panel P-1, and the panel reversing device 10 receives the reversing arm 1.
1 rotates from the vertical position and receives the panel P-2, which is in the pre-inversion position D, at the lower reversing part 13 with the gripping arm 16, while the panel that was already gripped by the gripping arm 15 in the upper reversing part 12 P-3 is inverted and placed in the panel inversion position C.

When the reversing arm 11 of the panel reversing device 10 turns 90 degrees from this state to the vertical state, the panel P-2, which was placed at the pre-reversing position D, is moved by the reversing section 13, as shown in b in the figure. The state is lifted upward, and the reversing arm 11 is in a standby state.
At the same time, the panel transport devices 4 and 5 move to close positions, and the panel transport device 4 transports the panel P-1 to the pre-reversal position D, and the panel transport device 5 transports the panel P-1 to the panel reversal position C. Receive the inverted panel P-3 that was placed there. Then, drawing and pressing are performed in this state.

Furthermore, the reversing arm 11 of the panel reversing device 10
When it turns 90 degrees and becomes horizontal again, as shown in c in the figure, each panel transport device 4, 5 has moved to a position away from the panel reversing device 10, as in case a, and the panel The conveying device 4 receives the next panel P-0, and the panel reversing device 10 receives the next panel P-0.
Now, while the panel P-2 held by the upper reversing section 13 of the reversing arm 11 is reversed and placed on the panel reversing position C, the panel P-2, which is at the pre-reversing position D, is placed on the lower reversing section 12. 1 gripping arm 1

When the reversing arm 11 of the panel reversing device 10 turns 90 degrees from this state to the vertical state, as shown in d in the figure, the panel P-1, which was placed in the pre-reversing position D, becomes the same as in the case b. , the state is lifted upward by the reversing part 12, and the reversing arm 11
is in a standby state. At the same time, the panel transport devices 4 and 5 move to close positions, and the panel transport device 4 transports the panel P-0 to the pre-reversal position D, and the panel transport device 5 transports the panel P-0 to the panel reversal position C. Panel P-2 in an inverted state
receive. Then, in this state, drawing and pressing are performed again.

Furthermore, the reversing arm 11 of the panel reversing device 10
When it turns 90 degrees and becomes horizontal again, as shown in e in the figure, each panel transport device 4, 5 moves to a position away from the panel reversing device 10, as in cases a and c. , the panel conveying device 4 receives the next panel P-4, and the panel reversing device 10 moves the panel P-1 held by the reversing section 12 on the upper side of the reversing arm 11 to the panel reversing position C.
At the same time, the lower reversing section 13 receives the panel P-0 at the pre-reversing position D.

By conveying and reversing the panel P in this way, one panel P can be reversed by rotating the reversing arm 11 180 degrees, and moreover, by keeping the reversing arm 11 on standby in a vertical position, , the conveying devices 4 and 5 can be brought closer to each other or separated from each other.

Therefore, it is possible to double the processing speed of drawing or press processing compared to the conventional method.

Furthermore, the installation interval between the two panel conveyance devices can be narrowed, and in this case as well, there is no interference between the respective devices.

In addition, although the above embodiment describes the inversion of the panel between the drawing process and the press process, the present invention is not limited to this, and can be applied to a wide range of cases where it is necessary to invert the panel.

Further, the configuration of the reversing arm and the configuration of the gripping arm are not limited to the illustrated example, and other mechanisms may be used.

[Effects of the invention] As described above in detail with one embodiment, the panel reversing device of this invention includes a plate-shaped reversing arm in which reversing portions are formed on both sides of the pivot axis, and Since the reversing arm is placed in a vertical standby position, one panel can be reversed by rotating 180 degrees, greatly increasing the processing speed. Therefore, the conveying devices can be installed close to each other and interference with each other can be prevented.
