The cylinder making machine generally includes a paper feed unit having a paper feed ruler movable in a direction perpendicular to the direction of transport of the blanks and a blank presser, and a plurality of units arranged in parallel in the direction of transport of the blanks for bending the blanks into new pieces. Each unit is movable in a direction perpendicular to the direction of conveyance of the blank,
In addition, an appropriate number of frames are provided so that the belt follows the bending line of the blank, and the position of each frame is controlled by a separate controller.However, in recent years, cylinder making has become a method of producing a wide variety of products in small quantities. ′ The number of blank sets has increased.

For this reason, the proportion of time spent replacing blanks in the working hours of -day increases, resulting in a decrease in work efficiency.

By the way, conventionally, the movement of the frame position of each unit due to blank replacement was controlled by the operator inputting the position of each frame individually into the controller.
This also required a lot of time and resulted in poor work efficiency.

In view of the above, the present invention has been made for the purpose of providing a method for moving a frame in a shida cylinder making machine so that the frame can be easily moved when replacing blanks. Control the positions of all frames in each unit by inputting three values: the dimension F from the center of the unit to the paper feed ruler, the width X of one side wall of the blank, and the width y of the other side wall. This is how it was done.

In order to control the positions of each of the belts 10 and the glue container 19, a main controller 20 shown in FIG. Each unit 4 is provided with a sub-controller 21 shown in FIG. 5, which is electrically connected to the main controller 20. Note that the sub-controller 21 in FIG. 5 is that of the unit 4C.

The main controller 20 has a pattern key 22a- and a T/key 22 for inputting blank B data.
Various keys 22 such as b-, F, x, and y selection keys 220, a storage device (not shown) for storing and reading out each dimension of the set blank B, a switch 23 for fully automatic simultaneous activation, Also provided is a display device 24 that informs the operator of each of the above-mentioned situations.

On the other hand, each of the sub-controllers 21 includes a pulse generator, rotary encoder, magnet scale, etc., for signal reading, comparison of set values, storage device when it is necessary to memorize each dimension of blank B, automatic origin calibration, etc. A discriminating device (both not shown) for moving to the + side and one side centering on 0 is built in, and these are controlled by a microcomputer (not shown). Also,
On the surface of the sub-controller 21, a number of display sections 25 corresponding to each frame 7 and glue container 19 are provided, and each display section 25 includes a digital display device 24, a digital switch 26, a manual movement switch 27, an automatic, A manual switching snap switch 28 and the like are provided. Further, on the side of the display section 25, a collision warning lamp 29, a snap switch 30 for automatic stop in the event of a collision, and a full stop switch 3 are provided.
1, a unit stop switch 32, a power indicator lamp 33, etc. are provided.

By the way, the microcomputer (not shown) of the main controller 20 includes the belt 10 and the glue container 19.
For the position of 10A'F (2x +2y) +210B:

Here, A: width of belt IOA B: width of belt IOB C: width of belt ioo, IOD, iog G: width of belt IOF, IOH D: width of belt 10G = 8 = H: width of belt 10, 10J Width x Width of side wall 12 of blank B y Width F of side wall 11 of blank B: Position of paper feed ruler 2.

Among the above-mentioned values, the width of each belt 10 is A% BXO%G
, D, , H are constant values regardless of the blank B of different dimensions, so the numeric keypad 22b of the main controller 20
You can enter it into your computer in advance using . Therefore, when replacing the blank B, use the numeric keypad 22b of the main controller 20 to enter the dimensions X and y of the two side walls 11A and 12A of the new blank B, and the position value F from the center of the paper feed ruler 2. When the data is input to the microcomputer, the computer performs calculations to calculate the positions of the glue container 19 and each transfer bell) 5.10°, that is, the frame 7, and move them.

In addition, n/2 appearing in multiple calculation formulas is belt 5.1
This is a term for controlling the position so that the edge of the width of 0 matches the folding line 13 instead of the center.

The above-mentioned movement control of the frame 7 includes a centralized control method in which the above-mentioned three types of data X% YsF are inputted through the main controller 20 when replacing the blank B, and a control method in which the blank B is stored by specifying its memory number. Digital switch 2 for each sub-controller 21
There are three individual methods for setting the dimensions of the blank B in step 6. Among these, the central control method and the individual method can be used as a storage method by storing the numerical values.

Next, the operation of the above-described embodiment will be explained. When setting the position of the frame 7 using the digital switch 26 for each sub-controller 21 individually, go to the unit 4 where the setting is required and set the position near the frame 7. Move the frame while checking the safety status of the attachments. Further, fine adjustment of the position of the frame 7 is performed manually using the manual movement switch 27 while checking the current position of the frame 7 on the display device 25.

Next, operate the fully automatic/simultaneous start switch 23 of the main controller 20 using the centralized control method or memory method,
When moving the frame 7 to the set blank B dimensions, if the work before changing the blank B dimensions is simple, there will be less obstruction between the frame 7 and the attachment or between both frames 7. The values of the dimension F at the position of the ruler 2 and the two dimensions xXy of the blank B are inputted using the respective keys 22, and each frame 7 can be moved all at once using the start switch 23.

Additionally, if there is an obstacle between the frame 7 and the attachment, or between both frames 7 and 7, the data from the main controller 20 is transferred to the sub-controller 21 of each unit 4 before the frame 7 starts moving. , go to each unit 4, check the current position and setting position of each frame 7 on the display device 25 of the sub-controller 21, remove any obstacles, and then return to the main controller 2.
Return to 0 and perform -simultaneous movement.

After controlling the movement of each frame 7, several 11-blanks B are fed into the cylinder making machine 1, and if there is a slight deviation in the completed box, operate the sub-controller 21 to move the frame again. Finely adjust the position of 7.

According to this embodiment, the main controller 2
3 data to 0 , can be performed for each unit 4 by the sub controller 21, so the main controller 2o
There is no need to go back and forth between each unit to make adjustments.
The time for adjustment can be significantly reduced.

In addition, since the sub-controller 21 is arranged for each unit 4, even if a problem occurs in the equipment of one unit 4, it is sufficient to repair only that unit, and the entire cylinder making machine 1 needs to be repaired or stopped. No adverse effects. Furthermore, since the movement of the frame 7 can be controlled by the sub-controller 21 while checking the status of the cylinder making machine 1, it is possible to prevent troubles that often occur in the past, leading to damage to the cylinder making machine 1.

As explained above, the method for moving the frame in the cylinder making machine according to the present invention is to provide the controller with the dimension F from the center of the paper feed section to the paper feed ruler, the width X of one side wall of the blank, and the width of the other side wall. Since the positions of all frames are controlled by inputting three values, including the width y of This can significantly improve productivity.
