DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 1 The present invention relates to an automatic circular cutting device for cutting paper and other materials into circular shapes. "Related American technology and its problems" Rolled cardboard is wrapped in wrapping paper in the circumferential direction, and then both ends are closed with circular single-sided paper. There is a conventional circular cutting device for cutting paper as shown in Figure 7. In the figure, the center of a rectangular piece of paper 52 placed on a table 5l is pressed by a paper presser 54 provided at the tip of the vertically movable shaft of an air cylinder 53 so that the paper 52 can rotate horizontally. Then, one end of the paper 52 is artificially wedged into the upper slitter 55 and the lower slitter 58. Thereafter, the upper and lower slitter 55 and the lower slitter 56 are rotated in the directions of arrows 55a and 58a by a rotation drive device (not shown) attached to the rotation shafts of the upper and lower slitter 56. As a result, the paper 52 is horizontally rotated around the paper retainer 54 in the counterclockwise direction of the arrow 52a in the drawing, and is cut into a circular shape by the engagement of the upper slitter 55 and the lower slitter 56. However, with the above-mentioned conventional device, the number of sheets of paper that can be cut at one time is determined by the driving force of the rotary drive device that rotates the upper slitter 55 and the lower slitter 56, and the engagement of the upper and lower slits and the lower slitter, and the cut surfaces are uneven. It is limited by various conditions such as Also, due to the structure of the previous device, it was possible to cut a predetermined number of sheets of paper. It has to be replaced every time a cut is made, and 1 has to be manually inserted into the upper and lower slitters 55 and 56 each time, which is extremely cumbersome and has low work efficiency. Ta. Furthermore, since the material paper is rotated by the upper and lower slits 55, 56, there are various inconveniences such as the outer shape of the cut material is often not a perfect circle. [Object of the present invention] The present invention is capable of increasing the amount of paper that can be cut at one time, reducing the number of manual work steps and automating the process, and furthermore, making the cutting surface extremely circular and completely circular, and also allowing the cutting radius to be adjusted freely. We have made it possible to provide a rotating circular cutting device that allows cutting to be changed. [Means for Solving the Problem] In order to solve the above-mentioned problem, the self-U circular cutting device of the present invention has a slide shaft that is moved up and down by a first motor attached to a support, and a slide shaft provided at the bottom of the slide shaft. The slide shaft is equipped with an arm that is horizontally rotated by a second motor, a cutter that is moved vertically by a third motor attached to the arm is attached to the tip of this arm, and a restraining plate is provided at the bottom of the slide shaft. [Operation] The first motor attached to the column is driven to move the slide shaft up and down.

Further, the guide wooden body +7a is long and has a flange in the center, and has a screw 28a above the flange.
An adjustment bolt 26 having a diameter is inserted. Further, the adjustment bolt 26 is configured so that its tip can be locked by a stopper 27 within the recess 17c of the guide wooden body 17a. It is fixed with a hexagon head bolt 28. In addition, this hexagon socket head bolt 28 also fixes the flexible shaft 8 inserted into the adjustment bolt 26 at the same time, and the flexible shaft 1B is attached to the third motor 7.
It is connected to the output shaft of the speed reducer 7a. The female thread 26b of the upper flange of the slider +7b is screwed into the male thread 28a of the adjustment port 26, and the guide wooden body 1
A pedestal with wheels 3l is fixed to the lower tip of 7a with screws, and L is attached to surround the main body 17a.
A letter-shaped card 33 is attached. Further, a contact switch 15a is provided on the paper holding disc l5. Next, the internal structure of the cylindrical body 9 will be explained below using diagram I84. Inside the cylinder 9, a cylinder pedestal 20 is fitted and fixed to the slide shaft 4, and on the outer peripheral surface of the cylinder pedestal 20, contacts 21a,
2lb, 21c, 21d are fitted, and these contacts 2
1a, 2lb, 21c, and 21d are connected to a control circuit (not shown) by cords 24a, 24b, 24c, and 24d. Plan boxes 23a, 23b, 23c, and 23d each having a spring inside are provided on the inner wall of the cylindrical body 9 facing the contacts 21a, 2lb, 21c, and 21d, and these brush boxes 23a, 23b, 2
3c and 23d are brushes 22a, 22b and 22, respectively.
c, 22d are supported so as to be pressed against the contacts 21a, 2lb, 21c, 21d, and each brush box 23a. 23b, 23c, and 23d are connected to the third motor 7 by cords 25a, 25b, 25c, and 25d. Next, the functions and operations of each part will be explained below. The forward and reverse rotation of the first motor 5 controlled by the control circuit is decelerated by the reducer l3, and the slide shaft 4 is moved up and down by adjusting the rack 4a and the pinion gear 14 attached to the rotating shaft 13a of the reducer I1+3. I am working to make this happen. When the slide shaft 4 rises, the stopper 4b provided on the slide shaft 4 reaches the upper limit, and the switch 12
a and turn on this limit switch 12a, then. The control circuit is O of this limit switcher l2a.
The N operation is detected and the rotation of the first motor 5 is stopped. Also. Conversely, when the slide shaft 4 descends due to the reverse rotation of the first motor 5, the stopper 4b contacts the lower limit switch +2b, turning on the limit switch 12b. The control circuit detects the ON operation of this limit switch 12b,
The rotation of the l-th motor 5 will be stopped. As a result, the slide shaft 4 moves up and down within the range determined by the upper and lower limit switches 12a and +2b. Next, the operations of the second motor 6 and the third motor 7 will be explained. The rotation of the second motor 6 is decelerated by a reducer 8a, and the rotation of the second motor 6 is reduced by a gear reducer 8a.
Rotate. This rotation of the gear 6b causes the cylinder 9 by the gear 9a meshing with the gear 6b to rotate around the axis of the slide shaft 4. Due to this rotation of the cylinder 9, the cutter holder l7 at the tip of the arm 16 rotates in a perfect circle around the axis of the slide shaft 4. At this time, the brushes 22a, 22b on the inner surface of the cylinder 9. 22c
22d rotates with the cylindrical body 9 while tracing the outer peripheral surface t of the contacts 21a, 2lb, 21c, and 21d.
As a result, the contacts 21a, 2lb, 21c. The coats 24a, 24b, 24c, 24d connected to the brush box 21d and the cords 25a, 25b, 25c, 25d connected to the brush box 23a, 23b, 23c, 23d always maintain a conductive state. Therefore, the electric signal from the control circuit can always be supplied to the third motor 7 regardless of the rotation of the cylinder 9. The rotation of the third motor 7 driven by the electric signal from this control circuit is decelerated by the deceleration fi7a and rotates the flexible shaft 18. When this shaft 18 rotates, the adjustment bolt 2 attached to the base end of the shaft 18
6 rotates, and this rotating adjustment bolt 26
The stator 17b, which is screwed together, is screwed and moves up and down. After placing the paper material to be cut on the table 2, the operator issues a command to the control circuit to start cutting by operating a switch on a control panel (not shown). In response to this, the control circuit reversely rotates the first motor 5 to lower the slide shaft 4. And slide axis 4 maximum f
When the paper holding disc 15 of the section presses the material paper, the contact switch 15a is turned on. The control circuit is this switch 15
The ON operation of a is detected and the rotation of the first motor 5 is stopped. Furthermore, after this, the control circuit drives the second motor 6 to rotate the arm 1B connected to the cylinder 9, and also drives the third motor 7 to screw feed the slider 17b to move the canter 32 on the table 2. Lower it so that it bites into the material paper. The lowering of this cutter 32 is sequentially lowered each time the arm 1B rotates, and when the cutter 32 further descends to a predetermined lower limit position,
A contact switch (not shown) turns on. In response to this ON operation of the contact switch, the control circuit stops the lowering of the cutter 32 and reversely drives the third motor 7 to return the cutter 32 to its initial predetermined position. At the same time, the drive of the second motor 6 is stopped to stop the rotation of the arm l6, and the first motor 5 is further driven to raise the slide shaft 4 to the upper limit position limited by the limit switch +2a, thereby all operations are completed. Complete. Through the above operations, the material paper on the table 2 is sequentially cut into perfect circles centered around the slide shaft 4 and whose radius is the length from the slide shaft 4 to the cutter holder l7. The cutting radius is determined by adjusting the arm 16 in and out of the arm holder 9b. In the above example, the motors 5, 6, and 7 were ordinary electric motors, and the operation was restricted by limit switches and contact switches provided in each part, but the motors themselves were used as stepping motors to directly control the amount of rotation of the motors. You can do it like this. In this way, the paper holding disk 15 is provided at the bottom of the slide shaft that moves up and down, and this holds down the paper to be cut, and the cutter 32 of the rotating arm 16 provided on the slide shaft is aligned with the horizontal rotation of the arm 16. Since the paper is lowered in sequence, paper of any thickness can always be cut into perfect circles. [Effects of the Invention] As stated above, according to the present invention, the paper to be cut is fixed and the cuff to be cut is moved in a circular motion while the vines are sequentially lowered in this direction. It is possible to quickly and accurately cut a large amount of paper into a perfect circle with a small amount of power, without any irregularities on the cutting surface. In addition, since the paper itself does not rotate like in the past, the space occupied by the entire device can be minimized, and unlike conventional methods that could not cut paper larger than the table on which the paper is placed, it is possible to cut paper that is larger than the table on which the paper is placed. You can freely make decisions without any restrictions. Furthermore, the cutting radius can be freely changed, and the only process that requires human labor is replacing the paper material.
It is possible to easily cut large quantities with extremely accurate dimensions. Note that this device can also cut materials other than paper into perfect circles that can be cut with a cutter such as a.
