  As is clear from the above description, the present invention has the following effects.

<Effect of the Invention of Claim 1>
The material passed through the material through gap formed between the movable die and the fixed die provided with its position fixed opposite to the movable die is removed by the removal operation of the movable die, and the forming material is removed. A punching device for forming,
A helical shaft for moving the movable mold, and
A rotating threaded body that is screwed into the helical shaft and that reciprocally moves the helical shaft by a rotational movement;
Drive means for rotating the rotary screw body;
A control unit for controlling the driving means;
A maximum gap distance storage unit that stores a set maximum gap distance of a material passing gap for movably passing the material formed between the movable mold and the fixed mold provided in the control unit; With
The set maximum gap distance is determined by the maximum separation stop position of the helical shaft so that the gap distance is wider than the thickness of one piece of the material and narrower than the thickness of two pieces of the material. Since the punching device is characterized by being controlled as described above, the following effects can be obtained.
That is,
(1) The movable mold is reciprocated by the linear reciprocating motion of the spiral shaft by the rotating screw, and the pushing operation of the movable mold of the spiral shaft toward the fixed mold is a pulling operation, and “the setting” The maximum gap distance is determined by the maximum separation stop position of the helical shaft so that the gap distance is wider than the thickness of one of the materials and narrower than the thickness of two of the materials. That is, since the helical shaft that pushes the movable mold determines and regulates the material gap distance, there is no collision between the movable mold and the material through gap forming operation (when not pulled out).
Therefore, the vibration and noise during the pulling operation are only the driving sound of the driving means (generally a servo motor is suitable), the rotating sound of the rotating screw and the frictional sound with the helical shaft, and the pulling sound when the material is pulled out. The total vibration and total noise are equivalent to or smaller than the operation sound and vibration of a laser copy machine in a general office.
As a result, a card forming device consisting of a card removing device linked to a printing machine that prints a picture of a card or the like on a plate-shaped or sheet-shaped material is also installed in a place where quietness is required, such as an office, and a card or the like is installed. It is possible to create and issue.
In addition, since vibration is extremely small, small size, and light weight, there is almost no need to reinforce the base part of the place where it is installed. It can be easily realized without reinforcing the floor.
Further, since the vibration is low, adverse effects due to vibration on the fixed type, the movable type, and the apparatus are greatly reduced, so that the durability and stability of the entire apparatus are greatly improved.
(2) A maximum gap distance storage unit for storing the set maximum gap distance of the material through gap is provided, and the gap distance of the material through gap is wider than the thickness of one piece of material, and two pieces of the material Since the gap distance is narrower than the thickness of the spiral shaft, it is controlled so as to be determined by the maximum separation stop position of the helical shaft. The maximum gap distance corresponding to materials of different thicknesses can be quickly realized by simple and easy operation only by setting the maximum gap distance.
(3) The movement of the movable type is restricted by the rotational linear reciprocation of the spiral shaft, and the restricted movement is longer than the thickness of one material and shorter than the thickness of two materials. The operation is always regulated within the gap distance, and the rotation (forward / reverse rotation) of the spiral shaft is a slight rotation operation that does not cause any harm even if it is touched by a hand.
Accordingly, for example, if the bank card (thickness standard is 0.76 mm), the maximum set gap of the material through gap is, for example, 0.76 mm + 0.38 mm = 1.14 mm (appropriate between 0.9 mm and 1.4 mm) In this case, the position where the linear reciprocating motion and the movable distance are only 1.14 mm of the spiral shaft and the movable type.
That is, it is a movable movement of a 1.14 mm device, and during operation it is a movement with 0.76 mm of material in it, so a finger is put in a gap of 1.14 mm−0.76 m = 0.38 mm. There is no danger at all, and therefore a safe punching device (particularly suitable for pulling out materials of 1 mm or less from cards such as bank cards and credit carts) is realized without any danger such as pinching a finger.
Therefore, when extracting a material of 1 mm or less, there is no need for a safety enclosure surrounding the movable mold part and the spiral shaft, and a removal apparatus that is sufficiently safe even without a safety enclosure is realized.
(4) According to the above (1), it is possible to reduce the height to 1.5 m or less, which is easy for the operator to work, and to achieve a reduction in size, weight, and cost.
This realizes cost reduction in packing, transportation, installation location, ease of assembly and installation.
Moreover, since only the driving system such as the servo motor and the control system including the setting display consume electricity, high energy saving is realized.
(5) According to the above (1), since the operation unit is a simple structure that does not require much maintenance, such as drive means (generally a servo motor is suitable), a reduction gear, a rotating screw, and a helical shaft, There is no need for dirt maintenance such as to do, and there is an effect of realizing high reliability and high maintainability.
(6) Since the punching operation and the material through-gap forming operation are realized with the minimum movement distance of the spiral shaft and the stamping portion thereof, the prior art requires time until the next punching operation until the timing wheel makes one round. In comparison, since there is no such waiting time, a high productivity punching device is realized.
(7) For example, high-precision reciprocating stop control such as 1/100 mm and 1/1000 mm can be easily realized depending on the gear ratio. Easy to do.

<Effects of Invention of Claim 2>
Since the helical shaft is a ball screw and the rotary screw is a ball screw nut, the punching device according to claim 1 has the same effect as that of the invention according to claim 1 and is described below. Has an effect.
That is,
Achieves lower vibration, lower noise, smoother operation, higher accuracy of stop position and higher durability.

<Effect of the Invention of Claim 3>
A movable mold and a fixed mold are integrated on the same guide shaft,
A separation elastic body that functions to always separate the movable mold and the fixed mold by a repulsive biasing force is provided,
The separable distance of the movable type that can be separated by the separation elastic body is a separation distance exceeding a set maximum gap distance,
The separation device according to any one of claims 1 and 2, wherein a separation speed for separating the movable mold of the separation elastic body is faster than a separation speed of the spiral shaft. In addition to the same effects as those of the invention described in any one of the above, the following effects can be achieved.
That is,
The separation distance of the movable type that can be separated by the separation elastic body is a separation distance exceeding the set maximum gap distance, and the separation speed for separating the movable mold of the separation elastic body is faster than the separation speed of the spiral shaft. This means that the movable type is always operating against the spiral shaft by the repulsive force of the separating elastic body, so there is no hitting sound due to the movable type movement, and the movable type and the helical shaft Has an effect of being an integrated operation like fixed members.
Thus, for example, in a die-cutting as shown in FIG. 7, it is not necessary to adjust and set the material passage gap in advance by the tightening means 6 (nuts etc.). Furthermore, the tightening means 6 (nuts etc.) Therefore, it is possible to speed up the disassembling and assembling work of the die.

When the meat portion remains, the punch edge blade and the out edge blade bite in, and the remaining meat portion breaks and the forming material is removed when the bottom dead center position is reached or more Since the punching device according to claim 3 is completed before, the same effect as the effect of the invention according to claim 3 is obtained and the following effect is also obtained.
That is,
The punch dead edge whose punch bottom edge is determined by the bottom dead center of the helical shaft, does not reach the out edge edge position where the punch edge edge bites into the material and becomes the other cutting edge of the forming material, and has penetrated into the material The remaining portion of the material remains between the outer edge blade and the outer edge blade, and the remaining edge portion breaks with the punch edge blade and the outer edge blade biting into the material to complete the removal of the forming material. As a result, the broken part of the periphery of the forming material becomes a smooth state due to the exothermic temperature at the time of extraction, and thus the periphery can be formed into a smooth material with no burrs, and the punch edge blade and the out edge blade Since the punching is performed in a non-contact manner, the durability of punching out is improved, and the punch edge blade and the out edge blade are not in contact with each other, so that the edge blades can be on the same line.

<Advantageous Effects of Invention>

While being supported on the body 8, a washer 57 is attached to the movable mold mounting portion 47 protruding upward from the movable mold 4, the fastening means 6 is screwed, and the movable mold 4 is fastened and moved by the fastening means 6. The separation elastic body 8 is compressed, and the movement of the movable mold 4 that attempts to move away from the fixed mold 3 by the repulsive elastic force of the separation elastic body 8 is restricted to about 2 mm to 10 mm by the tightening means 6 made of a nut. .
In the present embodiment, the thickness A of the material A regulated by the embossing portion 87 and the set maximum gap distance of the material through gap 7 are wider than 0.8 mm of the material A and more than 1.6 mm of two sheets. A narrow maximum clearance is set. Specifically, it is 1.4 mm. (In general, thin cards are about 0.25 mm, and credit cards are about 0.8 mm.)
In this state, the movable mold 4 and the fixed mold 3 are coupled and integrated.
The punching pressure of one 0.8mm-thick vinyl credit card (85.6mm x 54mm) is about 1.32t, and it is a combination of a ball screw and a ball screw nut. Is possible.

The set maximum gap distance is stored in a set maximum gap distance storage unit (not shown).
There are the following methods or methods for storing (setting) the set maximum gap distance in the set maximum gap distance storage unit.
(1) The material is passed through a gap wider than the material of the fixed mold 3 and the movable mold 4, the movable mold 4 is lowered, and the thickness of the material is displayed on a display (not shown) so as to be sandwiched between the material and both molds. Then, the movable mold is lifted from the position by approximately half the distance of the material, and the position is stored in the set maximum gap distance storage unit as the set maximum gap distance.
(2) Setting by numerical input. For example, if the material has a thickness of 0.8 mm, enter a number of 1.3 mm (select a number between 0.9 mm and 1.5 mm) or a large number of numbers (0 to 9). And the value is stored in the set maximum gap distance storage unit as the set maximum gap distance.
(3) One material is set between the fixed mold and the movable mold and the movable mold is operated so that one material is sandwiched between the fixed mold and the movable mold. Is stored in the “thickness storage unit for one material”, then two materials are set between the fixed mold and the movable mold, the movable mold is operated, and the material 2 is fixed between the fixed mold and the movable mold. In the state where the sheet is clamped, this sandwiching position is stored in the “2 material thickness storage section” as the thickness of 2 materials, and an appropriate position between the stored 1 material thickness and the 2 material thickness is set. The maximum gap distance is stored in the set maximum gap distance storage unit.
(4) One material is set between a fixed mold and a movable mold, and the movable mold is operated so that one material is sandwiched between the fixed mold and the movable mold. Is stored in the “one material thickness storage unit”, and a distance obtained by adding a distance smaller than the thickness of one material (for example, a thickness distance of ½ of the material) to the thickness of one material is set as the maximum gap. The distance is stored in the set maximum gap distance storage unit as a distance.

  The disengageable distance from the fixed mold 3 of the movable mold 4 that can be separated by the separation elastic body 8 is a separation distance that exceeds the set maximum clearance distance of the material passing gap 7, and the movable mold 4 of the separation elastic body 8 is separated. The separation speed of the helical shaft 83 is controlled to be slower than the separation speed to be made.

The material A is passed through the material through gap 7 and set. (See Figure 7)
The die pressing portion 87 that contacts and pushes down the receiving plate 26 moves downward while compressing the entire movable die 4 against the elastic repulsive force of the separating elastic body 8, and the flange storage body 36 and the punch-out guide body 19. Then, the material A is sandwiched between the movable punch 30 and the fixed punchout 22, and the lowering of the punchout guide body 19 is stopped by the flange housing 36.
Further, the die pressing portion 87 is lowered to contract the punch side compression elastic body 37, so that the flange side housing 36 cannot be lowered and the movable side punch 30 is lowered, and the movable side punch 30 is moved from the lower surface of the flange housing body 36. It protrudes downward.
The protruding movable punch 30 presses the fixed punchout 22 while holding the fixed punchout 22 and the material A therebetween.
The punched-out compression elastic body 20 is compressed and contracted by the pressed-out fixed-side punchout 22, and the fixed-side punchout 22 sinks (moves) into the punch-out guide body 19.
The material A portion pressed and clamped by the movable side punch 30 and the fixed side punch-out 22 by the sinking operation is punched from the material A to form the forming material B, and the extracted material C having a trace from which the forming material B has been extracted. Is formed. (See Figure 8)
When the die pressing portion 87 rises, the entire movable die 4 is lifted by the elastic repulsive force of the separation elastic body 8 while being in urging contact with the die pressing portion 87 (the separation elastic body 8 The movable die 4 is moved by stopping at a predetermined position of the die pushing portion 87 (the material through gap 7 is set to a maximum gap distance of 1.4 mm). The rise is stopped.
As the movable mold 4 is raised, the compression restraining force to the punch side compression elastic body 37 is released, the punch side compression elastic body 37 expands and pushes up the punch flange portion 29 with its elastic repulsive force, and the punch flange portion 29, the movable punch 30 integral with the punch 29 also rises, the punch flange 29 is pressed against the jaw 32 and stops. The movable punch 30 is entirely contained in the punch through hole 34, and its lower surface is the lower surface of the flange housing 36. Form the same surface.
On the fixed mold 3 side, as the movable mold 4 and the movable punch 30 are raised, the compression pressure to the punch-out compression elastic body 20 is released, so that the punch-out compression elastic body 20 expands and the punch-out flange is expanded. The punch 21 is pushed up and the upper surface of the punch-out flange 21 is brought into contact with the jaw 17 and stopped. As the punch-out flange 21 rises, the fixed punch-out 22 rises with the forming material B still on the fixed punch-off. The upper surface of 22 and the upper surface of the punch-out guide body 19 are flush with each other. Therefore, since the forming material B has no return place other than returning to the trace of the extracted material C, it is surely returned to the trace and the set maximum gap distance is set. The material through gap 7 of 1.4mm wider than one sheet of material A and narrower than two sheets allows the forming material to be transported without being removed from the trace even if there is warping. It is transferable to the section 98. (See Figure 9)

The separation elastic body 8 that separates the fixed mold 3 and the movable mold 4 by the elastic force is compressed by the mold pressing portion 87 so that the elastic repulsion force is strengthened.
Therefore, even after the punching operation is completed, the movable mold 4 to be pushed away by the separation elastic body 8 is stopped at the stop position of the mold pressing portion 87, and is also applied to the mold pressing portion 87 by the elastic repulsive force of the compressed separation elastic body 8. Since it is pressed, the vibration of the movable mold 4 is canceled by the elastic pressing force of the separation elastic body 8, and the movable mold 4 is stopped without fine movement to the set maximum gap distance position and without making a sound. doing.
Since the mold pressing part 87 presses the movable mold 4 and regulates the material passing gap 7 to a predetermined set maximum gap distance, it is also possible to use a clamping die without the clamping means 6, 6. , 6 can be set to an appropriate position.

The driving means 85 is controlled so as to stop at the maximum separation stop position at which 115 is obtained, and the bottom dead center 113 of the bottom dead center setting section 114 is also sent to the driving means control section 123, so that the driving means control section 123 spirals. The driving means 85 is controlled so that the shaft 83 stops at the bottom dead center position where the bottom dead center 113 is reached.
The detection data 128 for each punching operation is sent to the maximum gap distance determination unit 122. If the detection gap distance of the detection data 128 deviates from the set maximum gap distance 115, the maximum separation is performed without stopping the punching operation. The stop position is automatically changed within one reciprocating operation or several reciprocating operations so that the set maximum gap distance 115 is reached.
The set maximum gap distance 115 will be determined by the maximum separation stop position of the helical shaft so that the gap distance is wider than the thickness of one piece of material and narrower than the thickness of two pieces of material. It has become.
