(Problems to be Solved by the Invention) In the above-mentioned conventional system, the panel W placed in an upright state on the transport conveyor 1 in the driving state is then moved by the conveyor 1 by the feeding action of the transport conveyor 1. 1. Fall over and flip over. When the panel W is turned over due to falling, there is a problem in that the panel itself is distorted or broken due to the impact of the turning (turning over).

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, this invention uses a conveyor disposed between a first processing machine and a second processing machine, and a second processing machine. a swing arm jyo that clamps the end of the panel processed by the first processing machine and pulls the panel up to a predetermined position on the conveyor at a predetermined downward angle; and a swing arm jyo that is released at the pulling end of the swing arm jyo. and a support roller disposed at a predetermined height position above the conveyor to contact and support the upper front side of the panel placed in an upright state on the conveyor. A support arm is rotatably disposed at one end in front of the panel placed upright on the conveyor, and this support arm is held in a substantially horizontal state by a balancer. , a cup support is provided at the other end of the support arm so as to be movable in the arm direction of the support arm, and the cup support is provided with a cup support that is configured to abut against the front side of the panel in the upright state and separate the panel. A suction cup is rotatably provided to absorb the suction cup, and the suction cup is always held by a spring in a normal position facing the front side of the panel in the upright position, and the panel is moved by the conveying action of the conveyor. At the time of reversal, the support arm is supported by the balancer and tilts downward using its one end as a fulcrum, the cup support is pulled out in the direction of the support arm, and the suction cup is biased by the biasing force of the spring. It is configured to rotate downward against the resistance.

(Function) In the panel reversal auxiliary device in the panel reversal conveyance device configured as described above, the panel is placed in an upright state on the conveyor by the swing arm jaw, and the upper front side of the panel is placed on the support roller. When the panel is supported by the panel, the suction cup provided on the cup support of the support arm comes into contact with the front side of the panel and attracts the panel. The panels placed upright on the upper surface of the conveyor are successively tilted by the feeding action of the conveyor while the upper part of the front side is supported by the support arm via the suction cup. It is reversed along the upper surface of the conveyor. Further, the support arm that guides the inversion of the panel is tilted downward using one end as a fulcrum while being supported by the balancer, the cup support is pulled out in the direction of the arm, and the suction cup is in a state where the panel is suctioned. , rotate downward.

In this way, by inverting the panel along the top surface of the conveyor while the panel is attracted by the suction cup provided on the cup support of the support arm supported by the balancer, the shock of the panel inversion is reduced. It can be prevented.

Furthermore, when reversing the panel, the cup support is pulled out in the direction of the support arm;
By rotating the suction cup downward with respect to the cup support, the panel can be reliably supported from the upright position to the position where it is flipped onto the conveyor, and the support arm can be tilted downward from the horizontal position. The displacement angle to the position can be made as small as possible.

(Example) An example of this invention will be described below with reference to the drawings.

In FIG. 1, the conveyor 1, the swing arm 5, and the support rollers 8 are substantially the same as those of the prior art. That is, the conveyor 1 is configured by a conveyor belt 4 stretched between both driving and driven rollers 2 and 3, and a conveyor belt 4 is stretched between both driving and driven rollers 2 and 3.
It is arranged between the second processing machine (double press type) A and the second processing machine (single press type) B on the right side.

The swing arm jaw 5 has a fixed upper jaw 6 and a movable lower jaw 7 at its tip, and has a forward end position where it clamps the end of the panel W processed by the first processing machine A, and a forward end position where it clamps the end of the panel W processed by the first processing machine A. It moves back and forth between a pulling end position where the end of the panel W is held between two positions, and the panel W is pulled up to a predetermined position on the conveyor 1 at a predetermined downward angle.

The support roller 8 made of synthetic resin, rubber, etc. is a wire installed horizontally at a predetermined height from the top surface of the conveyor 1 and perpendicular to the conveyor 1 near the entrance side of the conveyor 1. 9
It is rotatably arranged around the The support roller 8 contacts and supports the upper part of the front side (right side in FIG. 1) of the panel W which is released at the pulled-up end of the swing arm 5 and placed on the conveyor 1 in an upright state.

In front of the panel W placed upright on the upper surface of the conveyor 1, there is a support arm 10 in the shape of a rectangular frame, with one end (the right end in FIG. It is rotatably installed as a. And this support arm 10
Always use balancer 12 (a commercially available one may also be used)
It is held almost horizontally by the

Left and right guide shafts 13 are provided on the other end (left end in FIG. 1) of the support arm 11 and protrude toward the front side of the panel W, and these guide shafts 13 have cup supports 14, It is inserted so that it can move freely in the axial direction and is prevented from turning. The cup support 14 is supported by a support spring 15 which is stretched substantially freely between the support 14 and the support arm 10.

At the tip of the cup support 14, a conveyor 1 is provided.
A suction cup 16 is rotatably attached by a pin 17 to abut the front side surface of a panel W placed upright on top and to attract the panel W in a separable manner. This suction cup 16 is urged clockwise in FIG. is maintained.

The suction cup 16 is connected to a bench lily 22 through a suction pipe 21, and the inside of the suction cup 16 is brought into negative pressure by the suction action of the bench lily 22. A solenoid valve 24 is disposed in the middle of a supply pipe 23 that supplies compressed air to the bench lily 22.

In this embodiment configured as described above, when the panel W is processed in the first processing machine A, the swing arm 5 moves forward to the forward end position and clamps the end of the panel W. Thereafter, the swing arm 5 moves the conveyor 1 while holding the panel W at a predetermined downward angle.
Pull it up to the specified position, stop at this pulling end,
Release panel W. Then, the upper part of the front side of the panel W is supported by the support roller 8, and the panel W is placed in an upright state on the upper surface of the transport conveyor 1 which is in the driving state. At this time, the front side of the panel W comes into contact with the suction cup 16.

As described above, when the swing arm 5 moves back to the pulling end, the solenoid valve 24 is opened almost at the same time, and compressed air is supplied to the bench lily 22 from the supply pipe 23. Then, the air inside the suction cup 16 is sequentially extracted by the bench lily 22. Therefore, when the panel W is placed on the upper surface of the transport conveyor 1 which is in the driving state, the suction cup 16 that comes into contact with the front side of the panel W is attracted to the panel W at the same time.

Therefore, the panel W placed upright on the upper surface of the transport conveyor 1 is supported by the support arm 10 via the suction cup 16 at the front upper part of the panel W, and is moved by the feeding action of the transport conveyor 1. It is then sequentially tilted and reversed along the upper surface of the conveyor 1. In addition, the support arm 10 that guides the panel W inverted is tilted downward about the support shaft 11, and the suction cup 16 is in a state where the panel W is suctioned.
It rotates about the pin 17 as a fulcrum and extends in the axial direction of the guide shaft 13.

At the same time or just before the panel W is reversed onto the upper surface of the conveyor 1, the limit switch (or a proximity switch) 25 is actuated by the downward tilt of the support arm 10, and the solenoid valve 24 is closed. Then, the suction action of the bench lily 22 is stopped, and the suction cup 16 is separated from the panel W.

Thereafter, the support arm 10 is returned to its original horizontal position by the balancer 12, and the suction cup 16 is returned to its original position by the return spring 18, while the panel W which is inverted on the upper surface of the conveyor 1
is transported towards the second processing machine B, where
One cycle of reversing and transporting the panel W is completed.

Note that the torque spring (not shown) built into the balancer 12 maintains a reversal speed such that when the panel W is reversed onto the upper surface of the conveyor 1, no impact force of reversal is applied to the panel W. It is assumed that the spring force is set to be sufficient to hold the support arm 10 and return the support arm 10 to its original horizontal state.

(Effects of the invention) As described above, according to this invention, when a panel placed upright on the top surface of a conveyor is reversed along the top surface of the conveyor by the feeding action of the conveyor, By inverting the panel along the top surface of the conveyor while the panel is attracted by the suction cup provided on the cup support of the support arm supported by the balancer, it is possible to prevent the impact of panel inversion. . As a result, it is possible to actively prevent distortion, breakage, etc. that occur in the panel due to the impact of panel inversion.

Further, when the panel is reversed, the support arm is tilted downward while the panel is being supported by the balancer, and the cup support is pulled out in the direction of the support arm, and the suction cup is pulled out from the support arm. By rotating downward, the panel can be reliably supported from the upright position to the position where it is flipped onto the conveyor, and the displacement angle of the support arm can be changed from the horizontal position to the downward tilted position. can be made smaller. As a result, it is possible to more reliably prevent the impact of panel reversal, and the time required for the support arm to return to its original horizontal position can be shortened by reducing the displacement angle of the support arm. This also has the effect of speeding up the reversal.
