Description

The present invention relates to a pre-cut device and a method for discharging pre-cut materials, which make it possible to discharge and efficiently pack pre-cut products for use in building construction while making effective use of space.

In order to make construction work more efficient, pre-cut products are packaged for each construction site and transported to the construction site. To this end, it has been proposed, for example, to pre-cut products used for openings in buildings for each opening in order to improve the efficiency of packaging operations (Patent Document 1).

Patent No. 6704875 Patent No. 5943977

For example, the number of products precut for use in a single opening in a building can range from a few to 20 or more. In order to take out the precut products one after another from the precutting device and package them, these products are sequentially discharged onto a discharge conveyor. A technique for sorting these products in the order of packaging has also been introduced (Patent Document 2).

If all the products to be packed are lined up on the discharge conveyor and the products can be taken out with plenty of time, packing can be carried out efficiently using the optimal packing method.

FIG. 1 is a block diagram showing an embodiment of a pre-cutting device of the present invention. FIG. 2 is an explanatory diagram (1) showing an example of a product discharge method. FIG. 2 is an explanatory diagram (2) showing an example of a product discharge method. It is a flowchart of the computer program which controls the operation|movement of the said pre-cut apparatus.

Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 depicts a known pre-cutting device 12 for processing feather pattern material. This device is controlled by a control computer 14. The control computer 14 stores precut data 16 in a storage device, and the control section 18 reads this precut data 16 to control the following devices.

Materials 20 to be precut are stacked on the input conveyor 22. These raw materials 20 are sent out one by one toward the conveyance path 26 by the feeding device 24.

The conveyance path 26 includes a roller conveyor, a belt conveyor, etc. for conveying the material 20. The processing device 28 is a device that precuts the material 20 according to the instructions of the precut data 16 under the control of the control unit 18 .

The conveyance path 26 is separated into an inlet side and an outlet side of the processing device 28, and is driven independently to convey the product 30. Inside the processing device 28, a clamp (not shown) grasps and moves the material 20 to perform pre-cutting.

The product 30 precut by the processing device 28 is sent out on the conveying path 26 in the direction of arrow A shown in FIG. 1(a) (conveying direction). When the rear end of the product 30 (the end on the processing device side) is detected by the rear end sensor 38, the conveying path 26 stops conveying the product 30.

The discharge device 32 is a device that pushes out the product 30 that has stopped on the conveying path 26 in the direction of arrow B (extrusion direction) toward the alignment conveyor 34. The alignment conveyor 34 has the function of moving the product 30 pushed out by the discharge device 32 in the width direction of the discharge conveyor 36 (direction of arrow C).

The alignment conveyor 34 is a device composed of a belt conveyor or the like that receives precut products 30 in order from the conveyance path 26 and aligns them in the width direction of the discharge conveyor 36 to a length that is equal to or less than the width of the discharge conveyor 36. .

The discharge device 32 has a function of pushing out the products aligned on the alignment conveyor 34 onto the discharge conveyor 36 all at once. The discharge conveyor 36 has a function of sending the extruded products 30 aligned in the width direction in the discharge direction (direction of arrow D) without disrupting the alignment. This is also a device composed of a belt conveyor and the like.

Figure 1(a) is a plan view of a comparative example of the discharge conveyor 36, and Figures 1(c), 1(d), and 1(e) are plan views of an embodiment of the discharge conveyor 36. For example, if the products 30 are discharged as shown in Figure 1(b), and the length of the discharge conveyor 36 in the direction of arrow D is 1.2 m, the discharge conveyor 36 will be full with about 10 products.

On the other hand, if the products 30 can be arranged in a length of, for example, 2 m in the width direction, about three times as many products can be delivered to the discharge conveyor 30 as shown in FIGS. can be placed on top. This increases the storage capacity of the discharge conveyor 36 and allows the packing work to be carried out with plenty of time while taking out the products 30 one by one.

In FIG. 1C, the products 30 arranged in the width direction are sequentially discharged on the discharge conveyor 36 with their right ends aligned. In addition, in FIGS. 1(d) and (e), in order to prevent the load from collapsing when packed, the gaps between the products 30 arranged in the width direction do not overlap when viewed from the discharge direction, and the products 30 are arranged in order. It is being discharged.

An example of a method of arranging the products 30 will be introduced below, but the method of arranging the products is arbitrary. For example, it is also possible to align the products 30 on the conveyance path 26. Another method is to provide a function to sequentially stop and line up the products 30 on the conveyance path 26.

However, as described above, if a dedicated alignment conveyor 34 for aligning the products 30 is added to an existing line, there is no need to modify the existing conveying path 30. In addition, when various methods for arranging the products 30 are adopted, there is an advantage that the degree of freedom of computer control is increased.

Furthermore, in the above example, the pre-cut products 30 are arranged to a length that is less than the width of the discharge conveyor 36, but if this alignment length is set to the length for packaging, the arranged products 30 can be arranged all at once. It can be taken out and packed. In other words, it is possible to further improve the efficiency of the packing operation. In this case, for example, it can be linked with a device that automatically takes out products from the discharge conveyor 36 and packs them.

A specific procedure of the discharge method will be explained using FIGS. 2 and 3. First, in FIG. 2(a), a description will be given of a state where the product 30a is precut and is transported on the transport path 26 in the transport direction (direction of arrow A). When the rear end sensor 38 detects the rear end of the product 30a, the conveyance of the product 30a is stopped.

Next, in FIG. 2(b), the discharge device 32 pushes out the product 30a in the extrusion direction (arrow B direction). As a result, the products 30a are fed onto the alignment conveyor 34.

Next, in FIG. 2(c), the products 30a are sent on the alignment conveyor 34 toward the width direction of the discharge conveyor 36 (in the direction of arrow C). The product 30a is fed to a position where the next precut product 30b can be arranged behind the product 30a. This position is calculated from the pre-cut data 16.

At this time, the next precut product 30b is being conveyed onto the conveying path 26. In Fig. 2 (d), when the rear end of the product 30b is detected by the rear end sensor 38, conveying of the product 30 in the direction of arrow A is stopped at this location.

Next, as shown in FIG. 3A, the product 30b is pushed out from the conveyance path 26 toward the alignment conveyor 34 (in the direction of arrow B) by the discharge device 32.

Thereafter, in FIG. 3(b), the products 30a and 30b move on the alignment conveyor 34 in the width direction of the discharge conveyor 36 (in the direction of arrow C). The amount of movement at this time is also calculated from the pre-cut data 16.

At this time, the next precut product 30c is fed onto the conveyance path 26. When the rear end sensor 38 detects the rear end of the product 30c, the conveyance of the product 30c is stopped.

Thereafter, as shown in FIG. 3(c), the products 30c are pushed out from the conveyance path 26 onto the alignment conveyor 34 by the discharge device 32. The three products 30a, 30b, and 30c are now aligned in the width direction of the discharge conveyor 36. This total length is almost the width of the discharge conveyor 36. In the example shown in this figure, the width of the discharge conveyor is slightly wider than the length of one piece of material 20.

In this embodiment, each time the products of one material are aligned, they are collectively pushed out to the discharge conveyor. That is, the discharge device 32 pushes out a line of aligned products 30a, 30b, 30c from the alignment conveyor 34 in the direction of the discharge conveyor 36. As shown in FIG. 3(d), the discharge conveyor 36 sequentially transports a row of products that were lined up immediately before, and receives a row of products pushed out by the discharge device 32.

Note that it is also possible to first detect the tips of the precut products 30 with the tip sensor 40, and then align the products 30 while moving them toward the right side in order from the left end of the alignment conveyor 34 in the figure.

Further, in the above example, the discharge device 32 performed the operation of pushing out the products 30 from the conveyance path 26 to the alignment conveyor 34 and the operation of pushing out the aligned products 30 from the alignment conveyor 34 to the discharge conveyor 36. However, this operation may also be performed by separate and independent devices. Furthermore, the expression "push out" is used to distinguish it from conveyance, etc., but it is used in the same sense as "move."

The operation of the above alignment conveyor is controlled by a computer program. For example, the control shown in Figure 4 is performed. The operations of Figures 2 and 3 are also controlled in the same manner.

First, in step S11 in FIG. 4, the rear end of the precut product is detected. In step S12, it is determined whether the product can be pushed out onto the alignment conveyor 34. When the result of this judgment is YES, the process moves to step S13, and when the result is NO, the process moves to step S18.

Since there are no products 30 on the alignment conveyor 34 at the start of pre-cutting, the answer is YES. However, if there are several products 30 on the alignment conveyor 34 and there is no room for the next product to line up, the answer is NO.

If there is another product on the alignment conveyor 34 and a new product cannot be pushed out, in step S18, the products aligned on the alignment conveyor are pushed out to the discharge conveyor. Thereafter, it is determined in step S19 whether the pre-cutting has been completed, and the process returns to step S11.

In step S13, the products are pushed out onto the alignment conveyor. In step S14, the total length L of the product to be precut next is acquired. Then, in step S15, M=L+product interval G is calculated.

In step S16, the products on the alignment conveyor are moved by M. In this way, a gap equal to L+product spacing G is created. In step S17, it is determined whether the products can be moved on the alignment conveyor by L+product interval G. Next, it is determined whether there is room to extrude the pre-cut product.

If the result of this determination is yes, the process proceeds to step S11, where preparations are made to receive new products. If the result is no, the process proceeds to step S18. As explained above, in step S18, the aligned products are pushed out onto the discharge conveyor. If it is determined in step S19 that pre-cutting is not complete, the process returns to step S11.

In step S11 described above, the total length of the products when they are arranged is determined, and the products 30 are moved in the direction of arrow C (width direction) on the arrangement conveyor 34 within the range of this limit. Although the width of the discharge conveyor is the maximum, the limit can be set freely such as the length of the material 20 or the length of the package.

In step S16, the aligned products 30 are moved in the direction of arrow C (width direction), but the amount of movement can be freely set. This makes it possible to ensure that, for example, when aligning products 30 equivalent to one piece of material as shown in FIG. 1(d), the position of the gap between the previously aligned products does not overlap with the position of the gap between the next aligned products.
