Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of stacking a wide variety of molded products in an appropriate packing mode according to their cross-sectional shapes, and is used as auxiliary equipment on the molded product take-out side of a roll molding machine. It relates to a molded product stacking device used.

[0002]

2. Description of the Related Art In the case of a molded product such as a lightweight channel steel, a molded product is generally shown in FIG. 9 (the lightweight channel steel is shown).
1 is arranged side by side in a plurality of rows and stacked in a plurality of stages. In order to stack the molded products 1 as described above, the molded products 1 may simply be brought into close contact with each other and packaged. Therefore, the molded product stacking apparatus for stacking the molded products 1 has one of the molded products 1 in advance as shown in FIG. 9B. They are inverted and combined, and the pairs are arranged side by side in a row so that they are pressed against each other. Then, the lifter on which the stacked molded products are placed is lowered to arrange the next stage horizontally in a plurality of rows.

[0003]

Since the general form of packing the molded products is the above-mentioned stacking procedure, the conventional molded product stacking apparatus does not have a problem with the positional accuracy of the molded products in the lateral direction. . However, in the case of molded products such as stainless molded products that are likely to be damaged by contact with each other, it is not preferable to simply pack them in close contact with each other. In order to prevent scratches, it is conceivable to interpose a scratch prevention member such as a slip sheet for preventing scratches between the molded products. Even if such a scratch prevention member is attempted to be interposed, a conventional molded product stacking apparatus is used. I can't handle this. That is, in order to interpose a scratch prevention member or the like, it is necessary to make the side-by-side spacing of the molded products accurate, but in the conventional molded product stacking device, they are simply brought into contact and arranged.
Precise side-by-side spacing cannot be ensured.

Further, although the cross-sectional shapes of the molded products are various, it is a conventional molded product stacking apparatus to stack the various molded products in an appropriate packing mode according to their cross-sectional shapes. I can't.

The present invention has been made in view of the above circumstances, and it is possible to stack a wide variety of molded products so as to have an appropriate packing mode according to their cross-sectional shapes. An object of the present invention is to provide a molded product stacking device that can be packaged so as not to be damaged.

The stacking operation of the molded products (the case of the lightweight channel steel in the illustrated example) by the above-described molded product stacking apparatus 10 will be described mainly with reference to FIGS. 4 to 6, the order of steps is indicated by a serial number of. In the initial state, the slider 14 and pusher 15 stand by at the slider initial position and the pusher initial position (positions in FIGS. 1 and 2), respectively. As shown in FIG. 4 (slider advancing step), the slider 14 starts moving forward when the molded article 1 reaches the vicinity of the tip of the lateral feed conveyor 11 by detecting it with a sensor (not shown), and receives the molded article 1 as shown in FIG. (Pusher lowering step) Moves forward to the forward end. Next, pusher 15
From the pusher origin position (position in FIG. 4) to the slider height position (height position in FIG. 4),
It moves forward by a distance set according to the order in which the molded products are sent. FIG. 4 (pusher advance process) shows a state in which the pusher has advanced by a set distance. Then, as shown in FIG. 5 (slider retracting step), the slider 14 is retracted and the pusher 15 is moved.
The molded product 1 stopped by is dropped onto the product pallet 13.

In the illustrated case, the operation is performed when the first molded product 1 is placed on the product pallet 13 and the subsequent second molded product 1 is placed on the product pallet 13, and the pusher 15 is the first molded product. 1, the molded product 1 that has fallen at a position spaced apart from the first molded product 1 has a space S from the first molded product 1 as shown in FIG. Next, as shown in FIG. 5 (pusher returning step), the pusher 15 is retracted to the pusher initial position.

Similarly, as shown in FIG. 5, the third molded product 1 is placed on the product pallet 13 and the first stage table (upward U-shaped placement is referred to as a table, and vice versa). After finishing all (referred to as the back), the inverted molded products 1 are stacked. In this case, the molded product 1 provided in the middle of the lateral feed conveyor 11 is inverted in advance, and is fed to the tip of the lateral feed conveyor 11 in this inverted posture, and the molded product 1 in the above table is paired with the same operation as described above. Drop it in the form of. In this case, place it slightly offset from the molded product in the table. Although details will be omitted, such stacking in the embodiment is performed with a slip sheet 40 (shown by a broken line) for preventing scratches on the molded product.
This is to intervene between the molded products. In order to arrange the interleaving paper 40 as shown in FIG. 6, the interleaving paper is placed on top at the stage of FIG. 5, and then the back side is stacked as shown in FIG. In order to perform such stacking, the molded product drop position determined according to the order of the molded products sent must be accurate. However, the pusher 15 can accurately control the molded product drop position. Can be stacked.

After the stacking of the front and back sides of the first stage is completed as described above, the product pallet 13 together with the lifter 12 is lowered by the height of one stage (FIG. 6 shows the state after the lowering). In the same manner, the second stage is stacked. When one package has two layers, the stacking is completed in the state shown in FIG. After that, the lifter 12 descends, and the carry-out conveyor 19
Receives the product pallet 13 and carries it out in the direction of arrow (c). The L-shaped product pallet 13 is an assembling type, and the frame material of the side wall portion is attached to the product pallet U-shaped after or before unloading. In addition, the carry-out roller 1
After unloading at 9, the wire is hooked on the wire hooking part (not shown) of the product pallet 13 and hung by a crane to be transported to a predetermined place.

FIG. 7 to FIG. 8 show the stacking procedure when the molded products have a special cross section. This molded product 1'has a generally V-shaped cross-sectional shape with a claw formed at one end, and since simple stacking is not appropriate, the product pillow 41 is placed at the end of the product pallet 13 as shown in the drawing, One side of 1'is stacked in such a posture that one side of the product 1'is on the product pillow 41. That is, one side of the V-shape of the molded product 1 ′ is stacked in the order in which it is sent, and the other side with the claws is arranged side by side in the order substantially standing on the product pallet 13. In this case,
7. The slider advancing process, the pusher lowering process in FIG. 7, the pusher advancing process in FIG. 7, the slider retracting process in FIG. 8, and the pusher returning process in FIG. 8 are basically the same as the above-described operation. In the case of this molded product 1 ', the operation of lowering the lifter 12 is not necessary. FIG. 8 shows a state in which the stacking for one package is completed. Although illustration is omitted, this stacking also envisions interposing a slip sheet between the molded products 1'to prevent scratches. In this case as well, it is necessary to make the intervals between the molded products 1'accurate, and the molded product stacking apparatus 10 of the present invention makes this possible.

The cross-sectional shape itself of the molded product applicable to the molded product stacking apparatus of the present invention is not limited to that of the embodiment. Further, although the present invention is for stacking molded products on a product pallet, the structure of the product pallet itself is not particularly limited.
