Description

[Detailed Description of the Invention] Industrial Application This invention is used for the setup of an automatic sheet folding machine. To further describe, the position of the folding guide and the position of the ruled line of the sheet in the automatic folding machine are described. The present invention relates to a setting device for an automatic folding machine that is ideally used for setting.

2. Description of the Related Art A ruled line is preliminarily formed on a sheet to be folded by an automatic folding machine in order to facilitate folding work. When folding this paper sheet from the ruled line, as shown in FIG. 3, the folding guide A is arranged in alignment with the ruled line L of the paper sheet P, and the paper sheet is sandwiched by the conveying belt B and the pressing belt C. P is moved forward and bent from the ruled line L by the bending guide A and the torsion plate S. In the figure, D is a frame to which the screw E is screwed, F is a support for the transfer belt B screwed to the screw, and G is a handle for rotating the screw E to move the support F. Show. (Actual Kimiaki
(See No. 58-2585) In this folding process, when the paper sheet P is bent, the inner surface of the ruled line L rises in a convex shape as shown in FIG.
I can make a bump K.

Conventionally, when positioning the folding guide A, the position of the ruled line of the paper sheet is set to the real side, the dimensions are driven into the keyboard, and the folding guide is once arranged at the value on the real side, and then the size of the bump is set. We are predicting that it will be finely adjusted.

Problems to be Solved by the Invention The conventional example has the following problems.

(1) Since it is necessary to set the bending guide once at a position that matches the ruled line and then finely adjust it in consideration of the size of the hump that occurs during bending, a large amount of adjustment time is required.

(2) Since the fine adjustment requires specialized knowledge and experience, an expert must do it.

Means for Solving the Problem The present inventor is aware that the size of the hump that occurs when the paper sheet is bent is related to the thickness of the paper, and the hump is bent without being affected by the hump. It has been found that in order to do this, the folding guide should be separated from the ruled line in accordance with the thickness of the paper sheet, and the folding guide should be arranged at the closest position where the guide does not come into contact with the hump.

Therefore, it was considered to create position adjustment data relating to the thickness of the paper sheet and the position displaced from the ruled line, and to automatically calculate the position of the folding guide using a computer based on these data.

Therefore, the present invention is configured as follows to achieve the above object.

A work stand on which a paper sheet is placed; a device provided on the work stand for measuring the thickness of the paper sheet; a device provided on the work stand for measuring the position of a ruled line formed on the paper sheet A computer for inputting the measurement data of both the devices and for inputting the position adjustment data regarding the shift position from the ruled line corresponding to the thickness of the sheet, and determining the position of the folding guide from the data. And a setting device of an automatic folding machine having;

Action Place the paper (work) on the work stand, measure the thickness of the paper with the device that measures the thickness of the paper, etc., and measure the position of the ruled line of the paper with the device that measures the position of the ruled line. . Then, when these measurement data are input to the computer in which the position adjustment data is input, the shift position of the folding guide corresponding to the thickness of the sheet is automatically calculated.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is a work table, 2 is a work (paper sheet) that is folded by an automatic folding machine, and 2a to 2d are ruled lines indicating folds. 3 is a setting device of an automatic folding machine, a device for measuring the thickness of the paper sheet, a device for measuring the position of the ruled line of the paper sheet, and a device for determining the position of the folding guide from the thickness of the paper sheet ( Computer) and.

As a device for measuring the thickness of the paper sheet, for example, a thickness detector 4 having a detection needle 4a is used, and as a device for measuring the position of the ruled line of the paper sheet, for example, a magnetic scale 5 and a detection head 6 are used.
As a device for determining the position of the folding guide based on the thickness of the sheet, for example, a thickness detector 4 and a detection head 6
The computer 7 electrically connected to is used.

Position adjustment data regarding the thickness of the paper and the position displaced from the ruled line is input to the computer 7. This position adjustment data is for separating the folding guide from the ruled line in accordance with the thickness of the paper sheet so that the paper sheet is not affected by the humps that occur during folding.

Then, when the thickness of the paper sheet is input, the computer 7 automatically calculates the position of the folding guide based on the position adjustment data.

The computer 7 is electrically connected to the automatic folding machine 8, and when the position of the folding guide is determined, the computer 7 automatically moves the folding guide of the automatic folding machine to the determined position.

Next, the operation of this embodiment will be described. The work table 1
The work 2 is placed on the work 2, and the magnetic scale 5 and the thickness detector are installed on the work 2.

When the detection head 6 of the magnetic scale 5 is moved to the direction of arrow A6 on the magnetic scale with the base point 0 determined and stopped at the position of the ruled line 2b, the magnetic scale 5 gives a pulse by the amount moved from the base point 0 (variable position). The number of output pulses is counted and used as the moving digital amount. For example, if a device that produces one pulse with a movement of 0.1 m / m (resolution) is used, a displacement output of 1000 pulses will be output from the magnetic scale 5 as a pulse with a movement of 100 m / m. This digital amount is input to the computer 7 in binary or decimal number, and the size from the base point to the ruled line 2b is read.

In this way, the dimensions of the ruled lines 2a to 2d of the work 2 are read.

When the detection needle 4a of the thickness detector 4 contacts the work 2, the thickness t of the work 2 is detected, and its value is
It is automatically input to the computer 7. Computer 7
The dimensions of the ruled lines 2a to 2d of the work 2 and the thickness t of the work 2 are
When the dimension of is input, the computer 7 calculates the position of the bending guide from the dimension of the thickness t of the work 2,
While determining the position, the position adjusting device (not shown) of the automatic folding machine is operated to move the folding guide to the determined position.

Other Embodiments The present invention is not limited to the above embodiments, and for example, an optical scale, a potentiometer, a magnetic encoder, or a pulse encoder may be used as a device for measuring the position of the ruled line of a paper sheet.

Effect of the Invention Since the invention is configured as described above, the work is placed on the work stand, the thickness of the work and the position of the ruled line are measured, and when the measured values are input to the computer, the thickness of the net leaf is determined. Correspondingly, the shift position of the bending guide is automatically calculated. If a bending guide is provided based on the calculation result, the ideal position for bending is obtained.

Therefore, it is possible to accurately know the ideal position of the folding guide in an extremely short time as compared with the conventional example, and it is possible to improve the operation rate of the automatic folding machine. Further, unlike the conventional example, even a non-specialist can easily and accurately determine the position of the bending guide.
