2. Description of the Related Art In a process of processing a printing material of a large diameter and a wide width (a printing material) and producing a printing material of various diameters (lengths) and widths, the width and length are processed to meet individual order requirements. Machine is needed. Such machines are known as slitting machines and comprise a cutter for slitting large width and length material sheets into demanding width and length demand sheets. Here, in the slitting machine, a slit width and a slit length are set in order to slit a demand sheet of a desired width and length.

[0003]

However, in the current slitting machines, the setting of the slit width and the slit length is constant during the charging of the material to be processed. Therefore, in order to change the setting, it has conventionally been necessary to temporarily suspend the operation of the slitting machine. For this reason, for various order requests,
It is necessary to supply high-priced large-diameter and wide-width printing materials without waste, and a device that can perform slitting work only by data input work in order to reduce the work load on workers. Machine control and work instructions (work instruction creation) Is required.

In the past, allocating demand paper to material paper simply involved arranging them in order of delivery date from the front. For this reason, many paper portions are not used as demand paper, and a large amount of extra material has been generated.

[0005] Further, the setting of the slit width and the slit length has conventionally been performed manually by manual instructions based on output materials such as paper. Therefore, it took a lot of time to create the instruction.

The present invention has been made to solve the above-mentioned conventional problems, and automatically sets a slitting machine capable of allocating demand paper to material paper without waste and reducing a portion of paper not used as demand paper. Accordingly, an object of the present invention is to provide a slit instruction control device capable of not only reducing the number of materials but also reducing the number of hands and improving the productivity by improving the operation speed.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided demand information indicating at least the outer dimensions and delivery date of a demand sheet obtained after slitting, which is input by an input device such as a keyboard.
And means for reading material information indicating at least the outer shape of the material paper as the raw material of the slit, and the delivery date of the demand information is allocated to the material paper in order from the earlier delivery date, and the unallocated portion If the delivery date can be assigned later, the above-mentioned problem is solved by providing a calculation means for performing the assignment.

[0008] In the slit instruction control device,
A means for transmitting the information of the result of the allocation to the slitting machine is provided, so that the setting of the slitting machine can be automatically performed by the transmission, thereby further reducing the manpower and further improving the productivity by improving the working speed. be able to.

FIG. 7 shows an instruction calculation process performed in this embodiment.

In this figure, first, at step 151, the DB
The demand DB 22 and the material DB 23 are read from the storage unit 20A of the server 20. In step 153, the demand data is sorted in order of delivery date, slit width, and slit length. In step 155, the material data is sorted in the material 1D order. In step 157, demand data material allocation processing is performed. The demand data material allocation process is shown in the flowchart of FIG. In step 159, the calculation result is written in the insertion order DB 24 and the slit position DB 25.

FIG. 8 is a flowchart of the demand data material allocation process.

In step 171 of this figure, a material loop counter and a demand data loop counter are initialized. In step 173, the material data loop up to step 183 is repeated until the following equation is satisfied.

(Material data loop counter)> (Total number of data in material DB) (1)

In step 175, as shown in FIG. 11, the unwinding left end of the material is set as a reference point (0). In step 177, step 181 is executed until the following equation is satisfied.
Repeat the demand data loop up to.

(Demand data loop counter)> (Total number of data in demand DB) (2)

Step 179 is an allocation process, and details are as shown in FIG. After step 183, the process returns to step 157 in FIG.
Go to 9.

FIG. 9 is a flowchart of the assignment process.

In this figure, in step 201, it is determined whether or not the target demand data has already been allocated. If Y, proceed to “return”; if N, proceed to step 203. In step 203, a demand data allocation position calculation process whose details are shown in FIG. 10 is performed. In step 205, it is determined whether the demand data can be allocated to the allocation target material. If Y, the demand data is assigned to the material in step 207,
At step 209, the demand data lube counter is reset. If the answer is N in Step 205 or after Step 209, the process proceeds to “Return”.

FIG. 10 is a flowchart of the demand data allocation position calculation process.

In this figure, first, in step 221, current allocation information such as an allocation start position, an allocatable width, and an allocatable length is stored. In step 223, a demand data allocation start position is calculated. This means that a demand data allocation start position of a material in which a demand data allocation start position is calculated is a position where Y (length direction) is close to the reference point and X (width direction) is also close to the reference point. Things.

The condition A in step 225 is to determine whether the following equation is satisfied. Condition A considers the case where the material to be allocated changes.

(Previous allocation target material) = (current allocation target material) (3)

The condition B in step 227 is to determine whether the following equation is satisfied. When there is no demand data that can be allocated, when the allocation start position is calculated again, it becomes the same as the previous position, and thus such a condition is determined.

(Previous allocation start position) = (current allocation start position) (4)

The condition C of step 229 is to determine whether or not there is a demand sheet (demand order) already allocated on the X coordinate of the Y coordinate of the obtained allocation start position.

First, when the condition A is Y and the condition B is Y, in step 243, the allocation target region obtained last time is excluded from the target regions for which the allocation start position is calculated. Thereafter, the flow branches forward to step 223.

If the condition A is Y, the condition B is N, and the condition C is Y, in step 242, the length (Y-axis direction) of the area to be allocated is determined by the Y coordinate of the allocation start position. It is assumed that the Y coordinate is subtracted from the slit end position of the demand data on the X axis (Y is fixed and X is an arbitrary straight line).
If there are a plurality of pieces of demand data, the demand data whose slit end position is not on the X axis and whose X coordinate value is large is selected. It is assumed that the width of the layout target area is obtained by subtracting the X coordinate of the layout start position from the material width.

When condition A is N, or condition A is Y
If the condition B is N and the condition C is N, it is assumed in step 241 that the Y coordinate of the layout start position is subtracted from the length of the material to the length of the layout target area.
The width of the area to be allocated is the material width.

Subsequently, after steps 242 and 241, the area and position of the layout target area are obtained from the length and width.

Hereinafter, Tables 1 to 4 described above are taken as an example.
The assignment of the demand paper to the material paper will be described. Table 1
In the demand DB 22 of the production order number “1111”
If demand papers from “1111” to “555555555” are sequentially assigned to material papers as they are, the result is as shown in FIG. 12, where the number of paper parts that are not used as demand papers increases and wasteful. Therefore, the assignment to which the present invention is applied is performed as follows. 13 to 25, the shaded portion is an allocation target area to which demand data can be allocated. Further, the mark "D" at the upper left of the allocation target area is the allocation start position.

First, in FIG. 13, the entire width of the material sheet is the area to be allocated. When the allocation target area is calculated for the allocation target area, first, demand data is allocated as shown in FIG. 14, and the production order number is “11111111”.
Demand paper is allocated.

Next, in FIG. 15, the production order number is “11”.
The right side of the demand sheet of “111111” is the allocation target area. When the allocation target area is calculated for the allocation target area, demand data is allocated as shown in FIG. 16, and a demand sheet with a production order number “33333333” is allocated.

Next, in FIG. 17, the production order number is “33”.
The right side of the demand sheet of “333333” is an allocation target area. When the allocation target area is calculated for the allocation target area, it is found that the demand paper is not allocated at all.

In FIG. 18, the production order number is “3333”.
The area under the demand sheet "3333" is the allocation target area. When the allocation target area is calculated for the allocation target area,
It turns out that no demand paper is allocated.

In FIG. 19, the production order number is “1111”.
Under the demand sheet of “1111” or “33333333”, the entire width of the material sheet is again the allocation target area. When the allocation target area is calculated for the allocation target area,
Demand data is assigned as shown in FIG. 20, and a demand sheet with a production order number of “222222222” is assigned.

Next, in FIG. 21, the production order number is “22”.
The right side of the demand sheet of “222222” is the allocation target area. When the allocation target area is calculated for the allocation target area, demand data is allocated as shown in FIG. 22, and a demand sheet with a production order number of “555555555” is allocated.

In FIG. 23, the production order number is “2222”.
Under the demand sheet of “2222” or “555555555”, the entire width of the material sheet is the area to be allocated again. When the allocation target area is calculated for the allocation target area,
Demand data is allocated as shown in FIG. 24, and a demand sheet with a production order number of “44444444” is allocated. At this stage in FIG. 24, all the demand sheets in Table 1 are allocated, and the allocation calculation ends. The end result is as shown in FIG.

FIGS. 24 and 25 made by applying the present invention.
Is less wasteful than the layout result of FIG. 12 described above. Further, the above-described assignment of the present embodiment is automatically performed by the slit instruction control device 10,
From the result, a loading order DB 24 and a slit position DB 25 can be obtained. Further, such a result can be automatically transmitted to the slitting machine control device 12 to automatically set the slit width and the slit length.

As described above, in the present embodiment, the present invention can be effectively applied. Therefore, by automatically setting the slitting machine capable of allocating the demand paper to the material paper without waste and reducing the portion of the paper not used as the demand paper, it is possible to not only reduce the material, but also reduce the number of hands and increase the work speed. Productivity can be improved.

[0067]

According to the present invention, by setting a slitting machine capable of allocating demand paper to material paper without waste and reducing a portion of paper not used as demand paper,
Not only the material can be reduced, but also the labor can be reduced, and the productivity can be improved by improving the working speed.

Further, according to the present invention, it is possible to reduce unnecessary material costs by creating a highly efficient material use instruction. By automatically creating instruction contents, the time for instruction creation conventionally performed manually can be greatly reduced.
