The present invention relates to a fully automatic perforator, and more particularly, to a fully automatic perforator for completing a process of perforating paper while the perforation drill moves automatically according to a preset program.

In general, the electric paper perforator moves to the base plate 1, the guide post bar 2 which is vertically mounted on the base plate 1, and the guide post bar 2, as shown in FIG. The member is guided and installed to move up and down, and the head portion 5 installed in the vertical direction so that the drill drill 4 is rotatable to the motor 3 provided therein, and the head portion 5 is increased by a predetermined distance. , The handle portion 6 for lowering, and the adjusting bar 7 for adjusting the lifting and lowering distance of the head portion 5.

In addition, the head portion 5 is provided with a pressing device associated with a pressing plate 8 which is pushed up and down vertically in front of the drilling drill 4 and fixed by pressing a document to be drilled at a predetermined pressure, and the base plate ( 1) is a scale is engraved on the scale plate (9) formed at the rear end vertically to adjust the punching interval, the upper side of the document guide plate 10 is formed with a vertical portion to align the side of the document during work Equipped

The general drilling machine configured as described above may interfere with the base plate 1 under the document when the drilling drill 4 descends more than necessary during the drilling operation, or the base plate 1 may also be drilled. Lower the adjustment bar (7) to adjust the length of the drill drill (4) is lowered so as not to interfere with the base plate (1).

Since the documents are distorted due to the rotational force of the drill drill 4 and the perforations of the upper and lower documents are not vertically formed, the documents are slightly distorted. When the handle part 6 was operated downward, the head part 5 was operated downward, so that the drill drill 4 rotated with the rotational force of the motor 3 to perforate the documents. In the case where a plurality of punched holes were drilled at regular intervals, the documents were moved continuously by measuring the distance between the punched holes with the scale on the scale plate 9 and measuring the gap.

However, when the conventional punching machine punches the documents at regular intervals, the distance between the punching holes is adjusted by measuring the scale manually, so that the gap between the punching holes occurs and the gap between the punching holes must be measured by the scale at the time of punching. Therefore, there was a problem in that the efficiency and precision of the drilling operation falls.

In addition, the conventional perforator has a problem that it is cumbersome to adjust the adjustment bar to prevent interference between the base plate under the paper and the blade of the perforation drill, and there is a risk of a safety accident due to difficulty in precise adjustment.

In addition, the conventional perforator has problems such as breaking the perforation blade when overload occurs during the perforation, there is a problem that there is a risk of safety accident because there is no device that accurately detects the overload.

In addition, in the conventional drilling machine, the motor driving the drilling drill is connected to the top of the drilling drill and rises upward, making it difficult to reduce the height of the product, which has disadvantages in space utilization and the high center of gravity. There was a problem.

In addition, the conventional perforator has a problem that there is a fear that the other side of the document does not reach the document guide plate is provided with a document guide plate to align the side of the document only on one side of the upper surface of the base plate.

The present invention has been made to solve the above problems, the object of the present invention is programmed so that all the operation is fully controlled by the microcomputer, so that pressing the button once, the table moves automatically while various kinds of perforations The present invention provides a fully automatic punching machine which continuously ends only once and prevents a punching gap error.

Another object of the present invention is to provide a fully automatic puncturer having a double means for detecting the moment when the puncture is completed to ensure that the puncture completion signal is detected by the other one even if any puncture completion detection means malfunctions have.

Another object of the present invention is to provide a fully automatic perforator with high safety by preventing accidents such as breaking the perforation blade by automatically stopping the perforation when the perforation motor is overloaded during perforation.

Hereinafter, with reference to the accompanying drawings illustrating a preferred embodiment according to the present invention in detail.

As shown in Figures 2 and 3, the automatic punching machine according to the present invention by pressing the main body frame 100, the table 200 to put the paper to be punched, and several stacked paper horizontally from above to fix the paper A paper clamp 230 for maintaining the horizontal portion of the perforated portion, a pair of left and right holders 210 having a vertical portion for aligning the left and right of the paper, and a holder support means 220 for supporting each of the fixtures, table Table conveying means 300 for moving the left and right, two guide rods extending vertically, a drill fixing body 140 through which the guide rod and guided vertical movement by the guide rod, and a drill fixing body 140 Perforated drill 150 which is supported by a bearing in the drill fixing body 140 and rotatably installed therethrough and vertically extended downwardly of the drill fixing body 140; Pushing means 190 and a drill fixing body 140 is installed in the drill fixing body 140 to be vertically raised and lowered from the front of the drill drill 150 and associated with a pressing plate 191 for pressing and fixing a drilling target. Perforated motor 160 fixedly coupled to the), the lifting and lowering motor 180 provided in the main body frame 100, the spur gear 182 connected to the shaft of the lifting and lowering motor 180, and the main body frame ( 100 and fixed to the pinion 183 engaged with the spur gear 182 and the drill fixing body 140 and engaged with the pinion 183 to move in the vertical direction in accordance with the rotation of the pinion 183. As a result, the rack 184 moves the drill fixing body 140 in a vertical direction, and a controller 400 including a circuit board, a microcomputer mounted thereto, a memory, a control panel for manipulation, and the like.

In addition, when the drill fixing body 140 reaches the highest point, the first limit switch 500 and the drill fixing body 140 which are in contact with a portion of the drill fixing body 140 to send a signal to the control unit 400 are at the lowest point. When reaching, the second limit switch 600 which contacts a portion of the drill fixing body 140 and sends a signal to the control unit 400 is installed at an appropriate position of the main frame 100. A portion of the drill fixing body 140 in contact with the first and / or second limit switch may be manufactured in a protruding shape relative to the periphery thereof. It is preferable that the 1st and 2nd limit switches consist of a hinge roller lever type switch.

The pressing means 190 in front of the drilling drill 150 is because the paper is not aligned vertically when the paper is distorted due to the rotational force of the drilling drill 150, the pressing plate 191 is a drill drill 150 Pressing the upper surface of the paper prior to this contact and the drilling drill 150 is to maintain the state of pressing the paper even during the drilling operation. A spring 192 is installed between the pressing plate 191 and the drill fixing body 140 so that the pressing plate 191, which has been lowered together with the drill fixing body 140, starts pressing the papers until the drilling is completed. ), The spring 192 is contracted as the pressure rises, and the pressing means 190 descends to the maximum by the unfolding force of the spring 192 when the pressing plate 191 is not in contact with the paper. The upper end is caught by the drill fixing body 140 and is moved up and down with the drill fixing body 140 without any lowering.

The body frame 100 forming the skeleton is made of a high strength aluminum alloy. In addition, the belt pulley 151 connected to the top of the drill drill 150 and the belt pulley connected to the top of the drilling motor 160 are not fixed to the drilling motor 160 on the drill fixing body 140 like the conventional electric drill. In the state where the drilling drill 150 and the drilling motor 160 are fixed to the drill fixing body 140 so as to have the same height, the belt 170 is hooked to both belt pulleys and the drilling motor 160 is mounted through the belt 170. Since the structure of transmitting the driving force to the drilling drill 150, the height of the product is reduced by the length of the drilling motor.

A motor encoder 181 for detecting the rotational speed of the motor is coupled to the rear end of the raising and lowering motor 180. When the drilling drill 150 punches paper, the load is applied to the motor. If the drilling blade is damaged or the drill hole is blocked, the drilling work is not performed smoothly. If the motor is overloaded, the rotation speed of the motor falls below a certain value. When the encoder 181 detects and delivers the control to the control unit 400, the puncturing motor 160 is automatically stopped to prevent a safety accident. There is also a method of determining whether the motor is overloaded by measuring the electrical resistance value of the motor, but since this method is not a good implementation of the function in practical terms, the perforator according to the present invention is a motor that accurately detects the motor rotation speed 100% The encoder is used to implement these functions.

The lower part of the control panel 400 exposed to the outer surface has a power switch, a start switch, a table shift switch, a drill drill and a reset switch for returning the table to its original position, a drill drill lowering switch, a drill drill A rotary switch is provided. In addition, the upper part of the control panel 400 is programmed so that all operations are fully controlled by the microcomputer so that when the button is pressed once, the table 200 automatically moves and the drilling ends continuously at once. There are 12 types of programs related to the punch type, and these buttons can be used to select any punch type.

4 is a plan view of a frame unit on which a table and a punch pad are mounted according to an exemplary embodiment.

When the drilling is completed and the drilling drill 150 reaches the lowest point, the drilling blade at the bottom of the drilling drill 150 touches the drilling pad 120 made of a conductive rubber material mounted in the groove of the frame portion. When the punch blade touches the punch pad 120 made of conductive rubber, it senses this and transmits an electric signal indicating that the drill drill 150 has reached the lowest point to the controller 400, and the controller 400 moves up / down the motor 180. Reverse the direction of rotation so that the drill drill 150 is raised. As a result of this action, the drilling drill 150 descends as soon as it touches the drilling pad 120. At this time, if the puncturing pad 120 is old, a malfunction may be reduced, but the second limit switch 600 having the same function detects a puncturing completion signal in a double manner, thereby causing a malfunction of the puncturing pad 120. The problem is reduced.

On the table 200, when the table 200 is in the center of the center, the scale is displayed as 0, and the numerical value is increased while going to both sides, so that it is easy to match the center of the papers, and A5 paper, A4 paper, B4 paper, etc. Straight lines drawn parallel to each standard sheet of paper are marked for easy alignment.

On the table 200, paper sheets are closely symmetrically positioned so that vertical sides of the “b” shaped holders for fixing and aligning the paper sheets are faced to each other. Fixture 210 is supported by the support means 220 is installed on both ends of the table (200). Fixture support means 220 has a passage is formed so that the fixture 210 is in close contact and pass in the left and right direction, the fastener 221 is screwed to tighten the fastener 221, the end of the fastener 221 is a fixture 210 When the stopper 210 is not moved and the fastener 221 is released without touching, the end of the fastener 221 which is in contact with the stopper 210 is moved from the stopper 210 so that the stopper 210 can move left and right.

It is a top view of the table conveying means in the state which removed the table.

As shown, the table conveying means 300 has a horizontal conveying motor 310 for generating power for moving the carrier 340, and two for conveying the power of the horizontal conveying motor 310 to the worm 330. Spur gear 320 and the worm 330, the screw thread is formed on the outer circumferential surface to move the carrier horizontally through the rotational movement, and the male thread of the worm 330 on the inner circumferential surface of the through hole and connected to the worm 330 Carrier 340 for moving the table 200 fixedly coupled to the upper end while the female thread is formed to be engaged to move horizontally in accordance with the rotation of the worm 330, and horizontally with the worm 330 while penetrating the carrier 340 The anti-rotation guide shaft fixed to the table carrying means 300 to prevent the rotation of the carrier 340 according to the rotation of the worm 330 to move the carrier 340 horizontally, and detects the position of the carrier 340 To prevent left and right separation of the carrier 340 and the center position It comprises a proximity sensor 360 for holding.

In the center of the front surface of the carrier 340, the reference detector 341 protruded forward and bent downward is fixedly coupled to move left and right along a straight path along with the movement of the carrier 340. The proximity sensor 360 provided on the circuit board 370 has a reference detector 341 when the reference detector 341 is moved to the left to the maximum, when it is moved to the right and at the middle, respectively. It is installed at the position to be detected and connected to the control unit. Limit switch may be installed in place of proximity sensor, but limit switch is slower than direct proximity sensor, has poor directivity, is affected by dust, etc., and has a short lifespan. It is preferable to use a proximity sensor as a means.

The rear side of the horizontal conveying motor 310 is provided with a motor encoder 311 for detecting the rotational speed of the motor so that the horizontal conveying motor 310 is rotated by the correct rotational speed under the control of the controller and the moving distance of the table 200. Precisely adjust the
