The detailed operation of the inversion piling device 22 will be described with reference to FIGS. In FIGS. 1 and 10, the suction arm 32 is in a standby state. The product 1 molded by the molding machine and cut to a fixed length by the cutting machine is conveyed in the direction of arrow a by the roller conveyor 20 which is a run-out table of the molding equipment, and stops by hitting the stopper 20a at the front end. Then, the suction arm 32 waiting on the upper side descends, and sucks the product 1 as shown in FIG. In the following description of the operation of the suction arm 32, the suction arm 32 will be described.
The lifting and lowering is performed by the lifting table 24 being driven by the lifting drive mechanism 28 to move up and down, and the suction arm 32 moves forward (moves to the right in FIG. 1) and retracts (moves to the left in FIG. 1). The horizontal movement of the suction arm 32 is performed by the horizontal drive mechanism 31 which is driven by the horizontal drive mechanism 31, and the suction arm 32 is rotated by the rotation of the shaft 33 which is driven by the rotation drive mechanism 34. However, the operation of these drive sources will be omitted, and description will be simply given of the up / down movement, forward / backward movement, and rotation of the suction arm 32.

As shown in FIG. 2, the suction arm 32 that has sucked the product 1 rises to the height position shown in FIG.
Then, it moves forward (moves to the delivery lifter 21 side) as shown by the arrow and is positioned above the delivery lifter 21 as shown in FIG. 4, and then, as shown in FIG. 5, on the adsorbed product 1 and the delivery lifter 21. It descends until the gap with the already stacked products 1 becomes narrow. Then, the attraction of the electromagnet 32b of the attraction arm 32 is released, and the product 1 drops and is stacked on the product already stacked on the delivery lifter 21. Suction arm 3 with products separated at the position shown in Fig. 5.
2 rises as shown by an arrow and at the same time rotates in a counterclockwise direction about an axis 33 as an arc arrow, and is folded horizontally as shown by a chain double-dashed line.

The folded back adsorption arm 32 continues to retract (moves to the left in the figure) to reach the position shown by the solid line in FIG. 6, and then descends to the position shown by the chain double-dashed line as indicated by the arrow.
Next, as shown by the broken line arrow, the vehicle advances and stands by under the roller conveyor 20 as shown in FIG. By this time, the next product 1 has been conveyed on the roller conveyor 20. Then, the suction arm 32 rises, and the suction arm 32 sucks and holds the product 1 on the roller conveyor 20 in the process of raising the suction arm 32.
Position of the product 1 and then rotated 180 ° clockwise as indicated by the circular arc arrow and positioned above the delivery lifter 21 as indicated by the chain double-dashed line. Is held in an inverted posture. In this way, the product 1 is inverted by the 180 ° rotation of the suction arm 32. Then, the suction arm 32 descends from the position of the chain double-dashed line in FIG. 8 as indicated by the broken line arrow, and the product 1 held by suction in the inverted state is transferred to the product on the delivery lifter 21 as shown in FIG. Close, then electromagnet 3
The adsorption by 2b is released and the product 1 is dropped. The product 1 that is dropped at this time is the opposite of the product that was previously stacked, and is stacked in such a manner that the irregularities of both products are engaged.

The suction arm 3 with the product 1 separated at the position shown in FIG.
2 rises and then retreats to return to the standby state of FIG. Hereinafter, the operations shown in FIGS. 1 to 9 are repeated to alternately invert the products and stack the products on the transfer lifter 21.

The delivery lifter 21 may be lowered by a predetermined amount each time, for example, a pair of products which are turned upside down are stacked, so that the height position for receiving the products from the suction arm 21 becomes constant. ..

Although the electromagnet 32b is used as the suction portion of the suction arm 32 in the embodiment, the suction portion is not limited to this, and may be a suction portion of a vacuum suction system, for example. Also,
The product targeted by the inversion piling device of the present invention is not limited to the flat deck plate as in the embodiment, but can be applied to various cases where it is necessary to alternately invert and stack upside down.

The inversion piling device of the present invention can also be applied as an inversion depiling device in which products are taken out one by one from the product group in which the front and back are alternately inverted and the front and back are in the same direction. In this case, the lifting drive mechanism 28, the lateral drive mechanism 31, and the rotation drive mechanism 34 are controlled so that the operation of the suction arm 32 is opposite to the above-described operation. That is, assuming that the products are alternately stacked on the transfer lifter 21 with the front and back reversed, the suction arm 32 sucks the uppermost product on the transfer lifter 21 in the state of FIG. After that, when it is turned 180 ° in the opposite direction of the arrow in FIG. 8 and folded back,
When the product 1 is held on the upper surface and is lowered from the position shown in FIG. 8, the product remains on the roller conveyor 20 as shown in FIG. 7, and the suction arm 32 is further lowered. Then, the suction arm 32 retracts to the left from the position shown in FIG.
After reaching the position indicated by the dashed line, it rises to the position indicated by the solid line, and the suction arm 32 advances from the position shown in FIG.
After reaching the position indicated by the dotted line, the suction arm 32 is rotated 180 ° clockwise (rotated in the direction opposite to the arc arrow in FIG. 5).
Located above the suction arm transfer lifter 21,
Next, it descends and picks up the product on the delivery lifter 21,
Then, after ascending to the position shown in FIG. 4, it retreats to be positioned above the roller conveyor 20 as shown in FIG. 3, and then descends to place the product 1 on the roller conveyor 20. By this time, the product previously dropped onto the roller conveyor 20 has been conveyed. In this way, the products stacked upside down on the transfer lifter 21 are taken out onto the roller conveyor 20 in the same direction. This reversal depiling device can be used, for example, when the panned product is subjected to some processing.

Although a roller conveyor is used as the transfer conveyor in the embodiment, the present invention is not limited to this, and may be, for example, a belt type conveyor divided into a plurality of parts. In short, it is sufficient if the suction arm has a space where the suction arm can move up and down at the position of the transport conveyor.

Further, in the above-mentioned embodiment, the inversion piling device is installed in the run-out table part of the cold roll forming equipment. ) Is applicable.

[0021]

According to the present invention, since the product is inverted and stacked by adsorbing and moving the product by the adsorbing arm and releasing the product, the collision noise of the product is small and the noise is reduced.

Since the suction arm which can be rotated by 180 ° and the movable table which is attached to the suction arm and is movable in the lateral direction of the conveyor and can be moved up and down, the equipment cost can be reduced.

Since the product is inverted and stacked by one device, space can be saved as compared with the conventional system in which the inversion device and the stacking device are separately provided. In addition, since the product is directly taken out from the conveyor and is subjected to the inversion piling, unlike the conventional method using the inversion device having the annular frame, it is not necessary to convey the product further forward from the inversion operation position. However, space can be saved. Further, unlike the conventional method using the reversing device having the first and second arms, a lateral feeding conveyor for laterally feeding the product from the feeding conveyor is not necessary, and in this respect, space saving can be achieved.
