Of course, to describe the preferred embodiment of the present invention, the base sheet 100 to be punched out to be fed to the die cutter 1 is limited to the base film 100 on which the pads 101 are arranged. However, And it is to be understood that the types of fabrics supplied for the punching operation in the die cutter 1 are very diverse and that the present invention is applicable to a variety of known sheet-like fabrics capable of performing punching operations in a die cutter .

1 to 3, the sheet feeding portion 10 is integrally disposed on one side of the main housing portion 60 which is one side of the striking portion 20, and the sheet feeding portion 10 Is provided with a guide frame 110 having a frame structure having a predetermined width so as to guide the transfer of the base film 100.

The guide frame 110 is fixedly disposed on one side of the main housing unit 60 and includes a horizontal frame 111 and a slant frame 112. The horizontal frame 111 has a flat plate- The inclined frame 112 is coupled to one side of the horizontal frame 111 and has one end formed as a free end, and a plurality of guide rollers 114 are arranged so as to be rotatable with a predetermined interval, I am taking.

The upper plate driving part is a driving part for moving the lifting and lowering shaft 124 up and down by crankshaft rotation. The upper plate driving part includes a main motor 125, a crankshaft (not shown) including a connecting rod, Not shown).

The crankshaft and the camshaft are driven through the motor drive to perform the one-stroke cranking operation, although the specific configuration is not shown in the figure because the upper-plate driving portion is located inside the main housing portion 60 It will be possible to fully understand the driving relationship even though it is not specifically shown in the drawings because it is a universal and well-known technology.

1, a main motor 125 for driving the crankshaft and the camshaft of the upper plate driving unit is mounted on one side of the inside of the main housing unit 60, as shown in FIG. 1 And the crankshaft and the camshaft are rotatably linked by the main motor 125 so as to be rotatably connected to each other and are formed inside the main housing unit 60. [

That is, each time the crankshaft and the camshaft are driven by the main motor 125 and the crankshaft rotates by one wheel (that is, one stroke), the ascending and descending axes 124 connected to each other by the connecting rod of the crankshaft The connecting rod of the crankshaft and the lifting / lowering shaft 124 are interlocked with each other so that the punching operation can be performed once.

As the main motor 125 is driven, the crankshaft and the camshaft are repeatedly rotated. When the crankshaft and the camshaft perform one rotation (i.e., one stroke) The punching operation is continuously performed in accordance with the intervals of the pads 101 on the base film 100 transferred from the sheet feeding portion 10 to the punching position of the punching portion 20, And is repeated.

The driving of the main motor 125 is automatically controlled through the control signal of the control unit 40, which will be described later.

1 to 3, the sheet discharging portion 30 is a portion for providing a driving force necessary for conveying the base film 100, and is provided with a striking portion 20 on the opposite side of the sheet feeding portion 10, And pulls out the base film 100 processed by the striking portion 20 and discharges the base film 100. [

The sheet discharging unit 30 includes a servo motor 130 for providing a driving force required to feed the base film 100 and an extrusion roller 131 connected to the servo motor 130 for rotation And an auxiliary roller 132 for engaging with the extrusion roller 131 to pull the base film 100 therefrom.

The servo motor 130 is a motor capable of controlling the speed of the servo motor 130 so that the servo motor 130 can control the speed of the servo motor 130. The servo motor 130 is controlled by the control unit 40, Speed control is performed precisely in accordance with the data value (that is, the pitch amount).

In other words, the sheet discharging unit 30 sequentially discharges the base film 100 by passing between the auxiliary rollers 132, which are in contact with the extrusion roller 131, At this time, the sheet discharging unit 30 is controlled by the amount of the conveying pitch of the base film 100 calculated by the control unit 40 (that is, the conveying distance of the base film 100) .

The control unit 40 is integrally disposed on one side of the main housing unit 60 as a unit for setting the overall operation state of the die cutter 1 and performing automatic control by a predetermined program.

As described above, the control unit 40 is provided with a controller having various control programs built therein, and is capable of appropriately setting a work state by an operator.

Particularly, the control unit 40 of the die cutter 1 according to the present invention controls the driving of the main motor 125 of the striking unit 20 and the driving of the striking unit 20 according to the feeding state of the base film 100, , And the driving of the servomotor 130 of the sheet discharging portion 30 is controlled.

That is, the distance between the pads 101 arranged on the base film 100 is detected by the mark sensor 151 of the detection unit 50, The speed of the servomotor 130 of the sheet discharging unit 30 is controlled so that the pad 101 is not detected in the position where the pad 101 is to be arranged in the detection signal sent from the detecting unit 50 The main motor 125 of the upper plate driving unit is stopped to temporarily stop the punching operation of the ascending and descending plate portion 120 by the ascending and descending operations so that the punching operation is not performed on the base film 100, The driving of the main motor 125 is repetitively and continuously controlled so that the main motor 125 is driven to perform a punching operation when the pad 101 having the pad 101 is placed at the punching position.

The process of controlling the punching operation through the control unit 40 is schematically shown in Figs. 5 to 9, and a more detailed description thereof will be described later.

The detecting unit 50 detects the feeding state of the base film 100 and is mounted on the horizontal frame 111 of the sheet feeding unit 10 as described above.

The detecting unit 50 includes a sensor unit 150 including a mark sensor capable of detecting the arrangement interval of the pads 101 arranged on the base film 100 and the arrangement of the pads 101, And a position adjustment guide unit 153 for adjusting the position of the sensor unit 150 by supporting and fixing the sensor unit 150.

The sensor unit 150 sequentially senses the arrangement position of the pads 101 in a scan form when the pads 101 arranged on the base film 100 are conveyed along the width control conveying path 113, 101 and the arrangement of the pads 101 can be calculated by the control unit 40. The sensor used in the sensor unit 150 may be a kind of distance measuring sensor The mark sensor 151 is used.

The mark sensor 151 is assembled and mounted in a state in which the sensing position can be finely adjusted through the sensor fixing bracket 152.

1 to 3, the mark sensor 151 is arranged close to the upper side of the base film 100 conveyed along the width-adjusting conveying path 113, so that the pads arranged on the base film The sensing signal is provided so that the control unit can calculate the arrangement interval of the pads 101 and the arrangement of the pads 101 in a sequential and continuous manner.

At this time, on the horizontal frame 111 on which the detection unit 50 is mounted, an arbitrary sensor sensing line L2 is set by the operator, from which the mark sensor 151 starts to sense the pad 101. [

That is, the sensor sensing line L2 is a position at which the mark sensor 151 is located. Since the mounting position of the mark sensor 151 according to the present invention is not always fixed at a predetermined position, As a result, the sensor detection line L2 can be arbitrarily changed by the operator.

Here, when sensing the pad 101 with the mark sensor 151 on the basis of the sensor sensing line L2, for example, as shown in FIG. 5, It is preferable to start the detection in a state where the front edge line of the pad F1 that first starts sensing is aligned with the sensor sensing line L2.

The position adjustment guide unit 153 includes a plurality of rail shafts 154 arranged vertically and parallel to each other to mount the sensor unit 150 and adjust the sensing position along the width direction of the base film 100 through slide movement, And a guide shaft 155 capable of sliding the sensor unit 150 in the lengthwise direction in which the base film 100 is transported while adjusting the sensing position while supporting both ends of the rail shaft 154.

The guide shaft 155 has a rod or a bar shape and is fixedly arranged at the both side edge portions of the upper end of the horizontal frame 111 in the form of both end support beams arranged side by side along the conveying length direction of the base film 100.

The rail shaft 154 is vertically and parallelly arranged with a bar or a bar shape. A sensor fixing bracket 152 of the sensor unit 150 is slidably fitted on the rail shaft 154, The slide block 156 is inserted and inserted into the guide shaft 155 so as to be slid along the guide shaft 155 in the conveying length direction of the base film 100, It is assembled to be able to adjust the position through movement.

Even in a state where the pads 101 to be punched are arranged at irregular intervals on the base film 100 in the process of performing the punching operation according to the present invention through the die cutter 1 having the above-described configuration, The automatic control process for supplying the electric power to the vehicle is as follows.

5 to 9 are schematic views illustrating an automatic control process for sequentially feeding pads arranged on a base film to an accurate punching position in a die cutter according to the present invention.

Here, the irregularly arranged pads 101 on the base film 100 shown in Figs. 5 to 9 are sequentially arranged in the order of F1, F2, F3, F5, F6, ... In order to facilitate understanding of the drawings, the present invention is described by exemplifying a state in which the pad 101 is not arranged at a position where the pad 101 is to be arranged on the base film 100, It is to be understood that virtual pads 101a and F4 are shown with dotted lines for the sake of clarity.

5 to 9, before the die cutting tool 1 according to the present invention performs a punching operation, the neck mold 122 on which the blade is mounted in the striking portion 20 is operated up and down A marking position aligning line L1 is set at a position where a punching operation is performed and a mark sensor PX serving as a detecting unit 50 is placed on the sheet feeding portion 10 which is a position spaced a predetermined distance S away from the punching position aligning line L1. (151), thereby setting the sensor sensing line (L2).

The punch alignment line L1 is set so as to coincide with the trailing edge line of the punching target pad 101 when viewed from the direction of conveyance of the punch 101 The sensor sensing line L2 is a state in which the front end edge line of the pad 101 that first starts sensing is aligned with the sensor sensing line L2 when the sensing direction is the transfer direction of the pad 101 5 < / RTI > (F1)).

The operator accurately measures the distance between the punch alignment line L1 and the sensor sensing line L2 and inputs the measured distance to the control program of the control unit 40. The operator also inputs the specification of the pad 101, The pad 101 on the base film 100 which is detected by the mark sensor 151 of the detection unit 50 and the pad 101 of FIGS. 5 to 9 , F2, F3, F5, ...) of the base film 100 on the basis of the detection signal for the irregular arrangement interval of the base film 100. [

When the preparation of the control preparation and the preparation of the punching work are completed with the basic data necessary for controlling the punching work being set as described above, the base film 100 requiring the punching work is fed from the sheet feeding portion 10 to the punching portion 20 And feeds the fed sheet onto the conveying path extending between the extruding roller 131 of the sheet discharging portion 30 and the auxiliary roller 132.

When the base film 100 having the irregularly arranged pads F1, F2, F3, ... is put into the die cutter 1 and the preparation for punching work is finally completed, (130) and starts to transport the base film (100).

As the base film 100 is transferred in this manner, the first edge line of the first pad to be punched 101 (i.e., the pad indicated by F1 in Fig. 5) is connected to the sensor sensing line L2 of the mark sensor 151 ) From the time of sorting.

At this time, the base film 100 is pulled between the extrusion roller 131 and the auxiliary roller 132 by being driven by the servo motor 130, and the first pad F1 to be punched is moved to the punching position F2 and F3 arranged on the base film 100 are scanned sequentially to scan the arrangement states of the pads F1, F2 and F3 to the control unit 40 .

Particularly, as shown in FIG. 6, when the trailing edge line of the first punching target pad F1 is positioned at the punching position aligning line L1 of the predetermined punching portion 20 of the operator, the first punching operation is performed .

The first punching operation as described above is performed by the control unit 40 in such a manner that the first edge line of the first punching target pad F1 receives a sensed signal as it is scanned from the point of passing the sensor sensing line L2, Since the traverse distance of the base film 100 is calculated on the basis of the measured distance S between the stroke L2 and the punch alignment line L1, A control signal for controlling the driving of the main motor 125 is sent out by the control unit at the time when the pawl 20 is positioned on the pawl alignment line L1 so that the crankshaft and the camshaft of the upper- The first and second punching target pads F1 accurately aligned on the punch alignment line L1 on the upper surface of the jig portion 121 are moved up and down one by one as the first and second punching target pads F1, And perform a punching operation.

When the punching operation is performed on the pad F1 to be punched in this way, the base film 100 is transferred to the sheet discharging portion 30 by driving the servo motor 130. [

At this time, the transfer distance of the base film 100 is such that the interval S1 between the first pad F1 and the second pad F2 is detected through the mark sensor 151 and the control unit 40 calculates the distance S1 The speed of the servomotor 130 is precisely controlled by the control unit 40 so that the trailing edge line of the second punching target pad F2 is aligned with the punching alignment line L1 (The distance of ejection of the base film 100 toward the sheet discharging portion 30) through the speed control of the servo motor 130 so as to coincide with the position of the base film 100.

When the second punching target pad F2 is aligned with the punch alignment line L1, the controller 40 controls the driving of the main motor 125 to perform the second punching operation in the same manner as described above The servo motor 130 is driven by the control signal of the control unit 40 to transfer the base film 100 to the sheet discharging unit 30. [

Since the control unit 40 calculates the interval S2 between the second pad F2 and the third pad F3 through the sensing signal sent from the mark sensor 151, The third pad P3 to be peened to be punched is controlled to the punching position alignment line L1 as shown in Fig. 8 by controlling the speed of the servo motor 130 by controlling the feeding distance of the base film 100 So that the distance of movement of the base film 100 can be controlled so as to be accurately aligned.

In this way, the control unit 40 calculates the arrangement interval between the pads F1, F2, F3, ... according to the preset control program according to the detection signal continuously transmitted as the mark sensor 151 scans. Control is performed to differentiate the transfer distance of the base film 100 according to the arrangement interval of the pads F1, F2, F3,... According to the calculated data values (data values according to the arrangement intervals of the irregular pads). That is, the control unit 40 controls the speed of the servo motor 130 to control the distance of the base film 100 to be differentiated according to the arrangement interval of the pads F1, F2, F3,.

Even if the pads F1, F2, F3, ... are arranged at irregular intervals on the base film 100 in the above-described manner, the pads F1, F2, F3, ), It is possible to improve the defective product due to the punching work and improve the process yield.

8 and 9, in the process of controlling the feed distance of the base film 100 through the speed control of the servo motor 130 in the control unit 40, There may be a case where the pad 101a is missing at a position where the pad 101 is to be arranged.

In such a case, as described in the related art, if the pads are not detected by the sensor in the related art, an emergency sound is generated and the punching operation of the die cutter is stopped to manually return the base film It was supposed to set.

However, in the case of the present invention, as shown in FIG. 8, a position where the pad 101a is not arranged on the base film 100 (for example, a virtual pad F4 shown by dotted lines in FIGS. The controller 100 stops the driving of the main motor 125 temporarily so as to temporarily stop only one punching operation and controls the drive of only the servo motor 130 in the control unit 40 The transfer distance of the base film 100 is increased by the length S3 in which the pad 101a is missing and until the next punching target pad F5 is aligned with the punch alignment line L1 as shown in Fig. By this transfer, subsequent punching work is performed.

In the process of repeatedly performing the punching operation, the main motor is stopped so that the punching operation is not performed on the base film 100, and the one-stroke operation of the crankshaft and the cam shaft is temporarily stopped, When the stamping operation is performed on the base film 100 without the pad 101a by controlling the motor 130 to be sufficiently fed until the pad F5 at the next position is located at the punch alignment line L1 It is possible to prevent breakage of the base film 100 that may occur and also to solve the problem that the die cutter must be set to an emergency stop and reset by the operator.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various changes, modifications and equivalents.
