Description

[Detailed Description of the Invention] Technical Field This invention relates to a pallet transfer device for concrete block molding.

PRIOR ART Concrete block molding pallets are molded by vibration and press pressure, so if they are repeatedly used one-sidedly every day, the distortion that occurs becomes large.

In addition, concrete sludge adheres to the surface in contact with the molded product, and this sludge gradually accumulates. Continuing to use the pallets in this state deteriorated the appearance of the products, further reduced the dimensional accuracy of the products, and sometimes led to the appearance of products that did not meet the specifications.

In the past, work was done to correct distortion, remove slag, or prevent adhesion, but recently, with the use of large molding machines, it is now possible to handle large pallets for the above work. It has become more difficult.

Purpose This invention is a pallet transfer device that is incorporated into a production line and has a device that continuously turns pallets.It reduces the work of correcting distortion and removing slag, and is thought to eliminate the work that occurs during turning. The aim is to provide a device that generates less noise.

Structure The structure of this invention is that one end of the pallet is supported by a rotary shaft 7 in the middle of the line that transfers the pallet after taking out the formed concrete block to the concrete block forming section, and the pallet is rotated from a horizontal position to a vertical position around this shaft. An upright plate 3 is provided with a driving piston 9 and a cylinder 2 at its lower part so as to be able to swing to a position, and has a pallet sensing contact point 1 on its upper surface, and a rotating shaft 8 adjacent to a rotating shaft 7 of this upright plate 3. Therefore, a pallet reversing device is provided which is pivotally supported at one end and has a receiving plate 5 having a driving piston 10 and a cylinder 4 at the bottom so as to be able to pivot from a horizontal position to a position where the pallet is transferred. This is a device for transferring pallets for molding concrete blocks.

The structure and operation of the device of this invention will be explained with reference to the drawings.Conveyor A (the left and right ends are cut and omitted) and conveyor B (the left and right ends are cut and omitted). The device of this invention is placed in the middle of a conveyor line for pallets 6 having It is located in In this state, the driving pistons 9 and 10 of the upright plate 3 and the receiving plate 5 are in the lowest position.

In this state, the pallet 6 sent by the left conveyor A is placed on the upright plate 3, and when its tip comes into contact with the pallet sensing contact 1, the cylinder 2
Then, the piston 9 for driving the upright plate, the cylinder 4, and the piston 10 for driving the receiving plate start to operate, the pistons 9 and 10 rise, and the upright plate is placed on the pallet 6 and rotates toward the rotating shaft as shown in the drawing. Turn around 7 and stand up almost vertically. At this time, the receiving plate rotates around the rotation axis 8 and rises to a position facing the pallet on the upright plate, and the pallet 6, which flies out due to inertia from the upright plate stopped in a vertical position and falls down, is shown in the drawing. It moves onto the receiving plate 5 as shown by the dotted line. The angle at which the receiving plate rises does not have to be vertical, but may be any angle that allows the receiving plate to receive the falling pallet reliably and with as little noise as possible.

When the pallet 6 moves to the receiving plate 5, the piston 9, the cylinder 2, the piston 10, and the cylinder 4 operate in the opposite direction to the upright position, and the upright plate 3 and the receiving plate 5 return to the state shown by the dotted line, and the pallet 6 is inverted from the state placed on the upright plate 3 and turned upside down.

When the receiving plate becomes horizontal, the pallet 6 is placed on the conveyor B from the receiving plate 5 and sent out to the right.
carried into position.

Effects As can be seen from the operation of the device of this invention explained above, this device allows pallets to be turned over safely and reliably in the middle of a continuous transfer line by a conveyor.

Furthermore, by inverting the pallet, the surface of the pallet that comes into contact with the concrete blocks is clean and free of concrete slag, and the forces acting on the pallet are also reversed, correcting the distortion of the pallet. Effective for maintaining product appearance and dimensional accuracy.

Further, the scum on the back side of the pallet falls off when the pallet is vibrated and deformed during use, and the surface becomes clean when the pallet is next turned over and used.

Therefore, the task of removing slag from the surface of the pallet can be reduced, and high-quality products can be manufactured.
