Part 2
It consists of a holding surface drive section that moves relative to the main holding section, a second arm for feeding that is shorter in length than the first arm, and a synchronous movement of the first and second arms in opposite directions. and a rocking device that swings the first main holding surface and the second main holding surface from a state in which they are horizontal to each other to a state in which they approach each other and face each other in a clasped palm shape, and vice versa; In the state facing the shape, the second
The arm is configured to swing at an angle of more than 90 degrees with respect to the horizontal line, and the first arm for receiving is set to swing at an angle of less than 90 degrees with respect to the horizontal line.

The reversing device of the present invention includes a base, a first arm,
It is composed of a second arm and a swinging device.

The base is for pivotally supporting the arm, and can be configured in various ways depending on the length, weight, etc. of the plate material.

The first arm is the same as the arm used in the conventional reversing device, and includes a first pivot part that is swingably supported on the base, and an arcuate part that extends in an arc shape from the first pivot part. Consisting of a first main holding part that forms a first main holding surface so that a plate can be placed thereon, and a first sub-holding part that forms a first sub-holding surface that extends substantially perpendicularly to the first main holding surface. has been done.

The second arm includes a second pivot portion pivotally supported on the base so as to be able to swing in the opposite direction in synchronization with the first arm, a second main holding portion forming a second main holding surface, and a second main holding portion that forms a second main holding surface. a second sub-holding part that is movable relative to the holding part and forms a second sub-holding surface that is substantially perpendicular to the second main holding surface;
and a holding surface drive section that moves the sub-holding section relative to the second main holding section. As the holding surface driving section, various conventionally known means such as a cylinder and a motor can be used.

The first arm and the number of first arms are not particularly limited, and may vary depending on the length and weight of the plate material to be reversed.
It may be one, or it may be two or more. In addition, when a plurality of arms are provided, it is desirable that the plurality of first arms or the plurality of second arms be driven by the same drive shaft so that they swing simultaneously. Also, the first
By interlocking the cardinal portion and the second cardinal portion, respectively,
It is desirable that the second arm be configured to swing in the opposite direction in synchronization with the swing of the first arm.

As for the rocking device, various conventionally known means can be used, and drive sources such as cylinders and motors can be used, and chain mechanisms, various link mechanisms, etc. can be adopted.

In addition, in the reversing device of the present invention, the arms that are open horizontally are brought together so as to pass from one arm (for example, the first arm) onto the other arm (for example, the second arm), but at this time, If the angle of inclination of the first arm is about 95 degrees, the plate material can be more accurately passed over the second arm.

In addition, conventionally known means can be used to place the plate processed in the previous process on the arm or to forward the plate after being turned over to the next process. For example, the method shown in FIG. As shown by the imaginary line, the plate material can be horizontally moved and conveyed using a belt conveyor.

[Operation] The reversing device of the present invention places a plate on the main holding part of one of the second arms when the two arms are opened horizontally, and operates the swinging device to bring each arm together. When the plate material is almost 100% held by the sub-holding section, the holding surface driving section is driven to swing the second sub-holding section, and the plate material is held by the sub-holding section of the other first arm. This is a device that rotates the two arms in opposite directions to turn over the horizontally opened plate after passing it by placing it on a holding part. That is, when the two arms are open in a horizontal state and the plate material is placed on the second main holding part of the second arm, the second arm and the first arm are synchronously swung so that their palms join together. When the holding surface drive unit is activated to lower the second sub-holding part, the plate is passed onto the first sub-holding part of the first arm, and by opening the arm again, the plate is reversed. It is held on the first main holding part of the first arm in this state.
