Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for palletizing single-sided packed products.

Conventionally, many plate-shaped products are generally packaged only on one side, and several of these are stacked and shipped and transported as a bundle. By the way, among the above-mentioned products, for example, in the case of wall board materials, they are stacked together to make a bundle with the packaging side facing forward, but inorganic wall board materials are resistant to external forces. There is a problem in that they are relatively brittle and break easily, and therefore, when they are bundled together, some kind of packaging method must be taken for the back non-packing side as well.

To solve this problem, as shown in Figure 1, when stacking several products B with packaging A on the surface, only product B', which is the outermost layer, is inverted so that packaging A' is on the outside. In some cases, the packages A and A' are stacked so that the packages A and A' are located at the outermost layer of the stacked product group.

The above-mentioned loading means is advantageous in terms of cost since there is no need to package the laminate in a separate process later, but when stacking, it is necessary to invert the last laminate, such as a turntable, etc. It is necessary to turn the product by 180 degrees every specified number of sheets using a machine, which causes the supply flow of the product to be intermittent, making it impossible to improve the processing speed.

In view of the above-mentioned problems, this invention was made with the aim of providing a pallet loading method for products packed on one side, in which the reversal of products after a specified number of products can be carried out smoothly without interfering with the product flow. The products are transported by a belt conveyor with the packing surface of the products facing a fixed side, either left or right, and are reversed at intervals slightly wider than the unit length of the products along the front and back of the flow direction of the conveyor. An edge is provided, and the product on the conveyor is pushed sideways so that the front or rear end of the product selectively comes into contact with either the front or rear edge of the reversing edge, and the product is reversed by contact with the reversing edge. The product group is characterized by stacking a plurality of products so that the packaging surface is exposed on the outermost layer surface of the product group.

Next, the present invention will be explained with reference to figures showing specific implementation means.

FIG. 2 is a plan view of an embodiment of the invention.

In the method of the present invention, first, a product 3 with packaging 2 applied only on one side is transported by a commonly used conveyor 1, such as a belt conveyor or a roller conveyor, so that the two sides of the packaging are facing the direction of travel (arrow P). , place it so that it faces either the left or right side (the right side in the figure), and transport it. On the sides of the conveyor 1, reversing edges 4A and 4B are provided along the flow direction (arrow P) with an interval L slightly wider than the unit length l of the product 3. , 4B, so that the product on the conveyor 1 is pushed out by the cross conveyor 5 or the like so that the front end 3A or the rear end 3B of the product selectively comes into contact with either one of the reversing edges 4A, 4B, and the product is pushed out along the chain line by contact with the reversing edges 4A, 4B. As shown, the product is turned over and a predetermined number of products 3 are stacked on the product receiver 6.

In the above, when the first product to be stacked is pushed out laterally from the conveyor 1,
The front end 3A of the product is brought into contact with the front end side reversal edge 4A, and the rear end 3B of the product is brought into contact with the rear end side reversal edge 4B for the last sheet.

Note that the means for selectively bringing the product 3 into contact with the front and rear edges 4A, 4B are the reverse edges 4A, 4B.
4B, product 3 transferred by conveyor 1
In addition to adjusting the timing between the speed of the cross conveyor 5 and the speed of the cross conveyor 5 appropriately using a synchronizing device, or using a counter device that counts products for each specified number of sheets, The reversing edges 4A, 4B are appropriately moved in a direction perpendicular to the extrusion direction (arrow Q) to select a contact position with respect to the product 3.

When the product 3 stacked as described above reaches a specified number, the pusher cylinder 9 is activated by the detection device 8 such as a phototube that detects this, and the product 3 is bundled into a bundle and then stored. It is transferred onto the ripper conveyor 10.

Since this invention is configured as described above,
When reversing the direction of the product every predetermined number of sheets, the product is pushed out by a cross conveyor, etc., and at the same time, the reversing edge is brought into contact with this, so the flow of the product is very smooth, and it is also possible to It has various effects, such as being easy to implement because it does not require large-scale equipment.
