Abstract

PURPOSE:To economize manhour by automatically transshipping and piling-up cubic shaped articles from the line for intermittently transporting said shaped articles onto the pallet on a dolly which transfers in each direction of back and forth, right and left, and downward. CONSTITUTION:When a shaped article 10 which is formed by cutting a material 9 into a prescribed length in a saw-cutter 1 is loading-disposed, the length of an expandable apron 3 is set so that the distance from the top edge of the apron to a stopper 8 on a pallet 4 is equal to the length of the shaped article. Then, the shaped articles 10 sent-out through the saw cutter 1 are arranged right and left in a prescribed quantity in the state where the front edge is attached onto the stopper 8, onto the pallets 4 which are arranged laterally in succession along a transversely advancing rail, and thus, the first array is formed. Then, a dolly 2 is advanced by the length of the shaped article 10, and the second array is formed through the same operation, and afterwards the third array is formed similarly. Thus, after the first layer is formed, the pallet 4 is lowered by one layer, and then the second, the third layers... are formed similarly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a line that sequentially and intermittently transports finished products of the same size and shape, using a pallet on a trolley that moves in each direction, front and rear, left and right, and downward. This is related to the method of re-pounding and stacking (cutting general vC purple lumber in a cutting area, etc., and using a conveyor supply device)
When dispensing a product, the product is written down manually or by a collecting device (magnet, crane). In the case of hunting with M amount such as copper plate v J Bonko Yoko, VC has the disadvantage that it is not a sword ≧ri that involves many dangers, but a harm is caused by the human body V and the koshiooke, etc., and accurately. It is a beautiful congratulations letter for a beautiful festival.

Our aim is to solve the problems of the conventional method and provide a method for automatically and accurately transshipping and stacking cargo without causing it to collapse.

That is, in the method of the present invention, the conveyed length t.

Cubic products 10 (including a group of multiple integrated products) with the same dimensions of width W and height h are intermittently sent out, and
In the direction of the X arrow in Fig. 1 (b), which is defined as the +X direction), b once in the feed direction (b in the direction of the X arrow in Fig. This provides a method for automatically and accurately stacking C pieces in sequence in the X arrow direction and +Z direction in FIG. 1(B).

Hereinafter, as an example, an embodiment will be described in which the method of the present invention is employed for cutting and stacking laminated steel materials.

In Figs. 2 and 3, 2 l uses a saw cutter to cut the long material 9 with saw teeth while intermittently extruding the material 9 to 1b.
The finished product is 10. The figure shows nine pieces of material being combined and cut. 3 is a telescopic apron which will be described later; 4
is a pallet on which cut products are placed. The pallet 4 is supported by the trolley 2, front and back (Y direction 1cIJ), left and right (
It can be freely moved in the X direction) and up and down (in two directions) by respective drive mechanisms.

In other words, the trolley 2-1 moves the rails on the base ll back and forth (in the Y direction).
The trolley 2-2 moves to the left and right on the rail on the trolley 2-1 (
The cart 2-3, which moves in the X direction) and supports the pallet 4, has a mechanism that allows it to be lifted up and down (in two directions) by means of a lifting device on the cart 2-2. Also, 6 is a one-legged fence installed on the apron 3, and 7 is a movable fence equipped with a spring, and while the product 10 is moving on the apron, it moves in a constant direction of movement toward the fixed fence on the left side. It turns out. 8 is a stopper on the top of the pallet 4 to control the flow of the finished product (1+stop position). Furthermore, the palette
Several short ribs 13 having a pentagonal cross section with one corner cut out are arranged in the direction perpendicular to the direction of movement of the product V on the upper curve of the product 4.The product can be transferred and placed on the pallet 4 without resistance. It looks like this.

On the other hand, the position detection switch l'7. , trolley 2-2
On the sides there are positioning dogs (movable as described below) in two directions, Yl.

xs + Zl, Z2 r z3'7j" is attached to the dog rail shoe 4. Yu 5. Yu 6, and can stop the pallet on the trolley at a predetermined position in X, Y, and Z by contacting the position detection switch. .Also, the positioning dogs Y, X, p-, and Z are all set at predetermined positions of the dog rail 141, truck 2-.z, and dog rail 16, respectively, to regulate the position at the start of loading. The function of the positioning sensor obtained from the position detection switch and the positioning dog may be replaced by various positioning sensors such as a phototube type or an electromagnetic sensor type.

In the above configuration, when loading products according to the present invention, the length of the telescopic apron is first adjusted so that the front end of the apron 3 and the front edge of the foremost product on the apron 3 are aligned. Fix it. That is, the length of the telescopic apron is set to be n times the finished product length t (n: a positive integer) from the cutting position (12 in FIG. 2).

In the example shown in the figure, it is 3t. Furthermore, the distance Nm from the tip of the apron 3 to the stopper 8 of the pallet 4 is set to the finished product length t, and the dog Y1 is fixed to the rail 14, and further Yl-Y2. Set the distance to t and add X2+. Similarly, dog X1. X2...X5゜XI X2

After the preparations are completed as described above, the material 9 is cut n11 times by the saw cutter. However, the first finished product was pallet 4
When the pallet is pushed upward, a signal indicating that the pallet on the cart can be moved is input to the computer. Then, the following operations are sequentially performed in accordance with the command signal (stop signal) for starting the next cutting.

0, + A predetermined minute distance is maintained so that the product transferred onto pallet 4 and the product on apron 3 to be fed next do not come into contact with each other when the pallet is moved to the left (X direction). Pallet 4 moves forward (Y direction) (
(■) in FIG. 4, this operation is performed using, for example, a time count that is input into a computer.

(2) Next, pallet 4 is moved at a distance of product width W (dog
X2] to the left (X direction). (■ in Figure 4) (3) Next, write (the small distance traveled at IJ &
(IJ (2) (3) Immediately upon completion of the operation, the command number (6) is released, and the next product is pushed out onto the apron s by the feeding device and positioned on the pallet 4.

As described above, the above operations are repeated one after another (■■■... . . .■ in FIG. 4) to finish arranging VCa pieces of products in the X direction. When the a-th product is sent out and the first product row is formed, the command signal (stop signal) is activated, and the pallet moves forward (in the Y direction by product length t (distance between Y + Yz)), and at the same time moves to the right. It moves aW distance in the -X direction and stops.

Next, perform the same operation as in the above-mentioned ``Yuta 1'' to line up the second row in the X direction. In this way, b products are placed in the Y direction. The first layer of products is now placed on the pallet 4, and the pallet is moved downward by a distance equal to the product height -gh due to the contact between the horizontal position switch 19 and the positioning dogs Z, , z2. (20,000 do). Dog X B I that simultaneously regulates the position i in the X direction
After returning to the position determined by the dog YF that regulates the position in the Y direction (the trajectory indicated by the dashed-dotted line in FIG. 4), it automatically returns to the positions Xl and Yl.

After that, repeat the same operation as for the first layer, the second layer, and the third layer.
Layering and loading continue. FIG. 5 shows the sequence of the above operations.

The above is true! One example is the simultaneous cutting of a long steel material with a saw cutter and the simultaneous feeding [7].Although we have described loading, it is also possible to apply this method to general transportation in which cubic products of a certain size are intermittently transported, reloaded, and piled up. Needless to say. As described above, according to the present invention, the core layer of the finished product can be neatly and accurately coated without causing the two parts to deviate.
