The goods are packed in a packing box having a size and shape that matches the shape and size.
When mass-producing goods, many packing boxes are required.
The developed parts to be assembled in the packaging box are cut out by cutting a plate-like material (for example, a corrugated board) into a predetermined shape.
In order to manufacture a large number of corrugated packaging boxes and plastics cases, a manufacturing method in which a desired shape is punched from a flat plate material such as corrugated cardboard, paper, or plastic sheet is often used.
A punching device is used to use this manufacturing method.

The outer shape punching blade is embedded in the die base plate by exposing the blade from the surface of the die base plate along the outer shape of the die to be punched.
The punching blade for a punching hole is embedded in the die base plate 21 by exposing the blade from the surface of the die base plate along the outline of the punching hole to be punched.
The blade of the punching blade 22 is exposed from the surface of the mold base plate 21 at a predetermined height. This exposed part is called a blade girder.

The pushing tool 23 pushes a punched piece from the punching blade 22. For example, the sheet-like member remaining surrounded by the punching blade when the punching shape is punched becomes a punched piece.
In general, the pusher 23 is an elastic body such as a synthetic rubber block having a thickness larger than the height of the blade girder.
A plurality of elastic bodies are mounted side by side on the mold base plate 21 along the blade girder of the punching blade 22.

  The pushing tool 40 is a block that presses a sheet-like material (corresponding to a workpiece) against the punching die 20 fixed to the die holder 30.

The operation of the punching device will be described below.
The sheet-like material is inserted into the gap between the punching die 20 and the pushing tool 40.
The pushing tool 40 is pressed against the punching die 20.
A sheet-like material is pressed against the punching die 20. The pusher 23 is compressed by the pressing force of the pusher 40.
The cutting edge of the punching blade 22 punches a sheet-like material and punches a punching shape having a desired shape.
The pushing tool 40 is pulled away from the punching die 20.
The pusher 23 tries to restore the compressed shape, and pulls the sheet-shaped material away from the punching die by the compression restoring force.
The sheet-like material in a state where the punched piece and the punched sheet-like material are integrated is pulled away from the punching device.
Thereafter, the punched scraps are separated from the sheet-like material to obtain a product having a desired shape.

In the product manufactured using the punching device, a mark pressed by the pusher 23 remains.
The thickness of the part with the trace pushed by the extrusion tool 23 of the product is thinner than the thickness of the flat plate-like material.

On the other hand, until the shape of a product to be mass-produced is determined, it is customary to make a prototype with a sample cutter.
Below, the structure of a sample cutter is demonstrated based on a figure.
FIG. 13 is a front view of a conventional sample cutter. FIG. 14 is a side view of a conventional sample cutter. FIG. 15 is a side sectional view of a conventional machine head.
A general sample cutter is an apparatus provided with a work head holding a processing tool on an XY plotter.
The sample cutter includes a work holding base 100, a work head 200, a work head moving mechanism 300, and a control device (not shown).
The workpiece holder 100 holds the workpiece 10 on the holding surface S.
The machine head 200 has a machining tool capable of cutting the workpiece 10 held on the holding surface S.
The machine head moving mechanism 300 is a mechanism that moves the machine head 200 parallel to the holding surface S.

The operation of the sample cutter will be described below.
A sheet-like material (corresponding to the workpiece 10) is held on the holding surface S.
When the machine head moving mechanism 300 moves the machine head 200 parallel to the holding surface S under the control of the control device, the processing tool 210 cuts the sheet-like material 10 into a desired shape.
The punched scraps are separated from the sheet-like material 10 to obtain a product having a desired shape.

Assemble the products made using the sample cutter and build the packaging box.
Conduct the specified strength test to confirm the strength of the packaging box.
When it is confirmed that the usability and strength of the packaging box satisfy the requirements, the design of the packaging box is finalized.
The punching die 20 is manufactured so that the packaging box whose design is determined can be mass-produced.
When the punching die 20 is manufactured, it can be incorporated into a punching device to mass-produce packaging boxes.

As described above, in the packaging box manufactured using the punching device, the trace pushed by the pusher 23 remains.
As a result, there was a problem in that the strength of the packaging box manufactured using the punching device was lower than that of the packaging box that was prototyped with the sample cutter.

The rotary joint 214 is a pipe connection member for supplying compressed air to the processing tool main body 213.

The machine head base 220 is a foundation structure that is supported and moved by a machine head moving mechanism 300 described later.
For example, the work head base 220 is a structure that is guided by a Y-axis linear guide 312 provided along a Y-axis direction on a Y-axis cross beam 311 described later so as to be movable in the Y-axis direction.
The work head base 220 is guided by a Y-axis linear guide 312 by a Y-axis drive motor (not shown) and reciprocates in the Y-axis direction.

The machine head moving base 230 is a structure that is guided by the machine head base 220 so as to be movable in the direction along the Z axis.
The machine head moving base 230 is supported by a linear guide provided on the machine head base 220 and extending along the Z axis, and is driven by the machining tool lifting mechanism 250 so as to be able to reciprocate along the Z axis.

The processing tool rotation mechanism 260 is a mechanism that swings the processing tool 210 about the Z axis and stops it.
For example, the processing tool rotation mechanism 260 includes an electric motor 261 and a drive belt 262.
The electric motor 261 is fixed to the work head moving base 230 and has a drive pulley on the rotating shaft.
The drive belt 262 is stretched around the drive pulley and the work head rotating table 240.
As a result, when the electric motor 261 is rotated forward or backward, the machining tool 210 fixed to the work head rotating base 240 rotates to one side around the Z axis, and the cutting edge of the cutter faces in either direction around the Z axis.

The machine head moving mechanism 300 is a mechanism that can move the machine head 200 along the holding surface S.
For example, the machine head moving mechanism 300 moves the machine head 200 parallel to the holding surface S.
For example, the work head moving mechanism 300 includes an X axis moving mechanism (not shown) and a Y axis moving mechanism 310.
The X-axis movement mechanism moves the Y-axis movement mechanism 310 back and forth in the X-axis direction and stops.
The X-axis movement mechanism includes an X-axis linear guide (not shown) and an X-axis drive mechanism (not shown).
The X-axis linear guide is a linear guide that is located in the vicinity of two sides along the X-axis of the workpiece holder and extends in the direction along the X-axis. The Y-axis moving mechanism 310 is guided by the X-axis linear guide so as to be reciprocally movable in the X-axis direction.
The X-axis drive mechanism is composed of a drive belt and an electric motor.
The electric motor is fixed to the workpiece holder 100 and has a drive pulley on the output shaft.
The drive belt is a timing belt that spans between a drive pulley and a driven pulley fixed to the workpiece holding base 100.
The Y-axis moving mechanism 310 is fixed at one place on the drive belt.
As a result, when the electric motor is rotated forward or backward, the Y-axis moving mechanism moves forward or backward along the X-axis.

For example, the Y-axis moving mechanism 310 includes a Y-axis cross beam 311, a Y-axis linear guide 312, a Y-axis drive mechanism (not shown), and the Y-axis moving mechanism 310. Consists of.
The Y-axis cross beam 311 is a beam structure extending along the Y-axis. Both ends of the Y-axis cross beam 311 are guided by the X-axis linear guide so as to be movable along the X-axis.
The Y-axis linear guide 312 is a linear guide that is fixed to the Y-axis cross beam 311 and extends along the Y-axis.
The machine head 200 is guided by the Y-axis linear guide 312 so as to be reciprocally movable along the Y-axis.
The Y-axis moving mechanism is a mechanism that drives the work head 200 in the Y-axis direction, and includes an electric motor and a driving belt.
An electric motor is fixed to one end in the longitudinal direction of the Y-axis cross beam and has a drive pulley on the output shaft.
A driven pulley is provided at the other end in the longitudinal direction of the Y-axis cross beam.
A drive belt is bridged between the drive pulley and the driven pulley.
The work head is fixed at one position of the drive pulley.
As a result, when the electric motor rotates forward or reverse, the work head 200 reciprocates along the Y axis. When the electric motor stops, the work head 200 stops.
When the X axis moving mechanism reciprocates the Y axis moving mechanism 310 along the X axis, the work head 200 reciprocates along the X axis.

As a result, the machining tool 210 can be moved closer to the holding surface S along the Z-axis by the machining tool lifting mechanism 250 so that the tip of the cutter 211 of the machining tool 210 is positioned in the immediate vicinity of the holding surface S.
In such a state, the cutting edge of the cutter 211 is directed in the advancing direction of the cutter 211 by the processing tool rotating mechanism 260 and the work head 200 is moved along the holding surface S by the X-axis moving mechanism and the Y-axis moving mechanism.
When the workpiece 10 is held on the holding surface S, the machining tool 210 can cut the workpiece 10.
Here, a line formed by cutting the workpiece is referred to as a cutting line G.

The pushing mechanism 400 is a mechanism that can push the surface of the workpiece along a cutting line G of the workpiece that can be cut by the machining tool 210.
The pushing mechanism 400 includes a pushing member 410, a pushing member holder 420, a pushing spacer 430, and a pushing base 440.

The pushing member 410 is a roller that rolls in contact with the surface of the workpiece 10 along the cutting line G.
Here, “rolling” means “moving while rotating”.
When the machining tool cuts the workpiece, the pushing member 410 may be able to crush the workpiece.
One pushing member 410 may be disposed on one side across the cutting line G, and may roll along the cutting line G in contact with the surface of the workpiece.
One pushing member 410 may be positioned beside the cutter 211 and roll in contact with the surface of the workpiece 10 along the traveling direction of the cutter 211.

The pair of pushing members 410 may be positioned facing the side of the cutter 211 and may roll in contact with the surface of the workpiece 10 along the traveling direction of the cutter 211.

The pushing member holder 420 is a member that supports the pushing member 410 in a rollable manner and is supported by the work head 200.
For example, the pushing member holder 420 is supported at the end of the work head rotating table 240.

The pushing spacer 430 is a part that adjusts the relative distance between the pushing member 410 and the holding surface S.
For example, the push spacer 430 can adjust the relative distance in the direction along the Z axis between the tip of the cutter 211 and the rolling surface of the push member 410.
When a tail push spacer 430 having an arbitrary thickness is selected from a plurality of push spacers 430 having different thicknesses, the direction along the Z axis between the tip of the cutter 211 and the rolling surface of the push member 410 is changed. The relative distance can be arbitrarily selected.
As a result, the relative distance between the pushing member 410 and the holding surface S can be adjusted.

The push-in base 440 is a member that is fixed to the end of the work head rotary table 240 and into which the push-in member holder 420 is fitted.
The pushing-in base 440 is fixed to the work head rotating base 240 with bolts.
The pushing member holder 420 is guided by the pushing base 440 and is movable in the Z-axis direction. The set screw can fix the relative movement of the push-in member holder 420 and the push-in base 440 in the Z-axis direction.

When the work head 200 is moved along the holding surface S, the cutter 211 cuts the workpiece and creates a cutting line. The conical surfaces of the pushing members 410a and 410b squeeze the portion along the cutting line while rolling.
When the work head 200 is retracted, a mark is formed on the workpiece by crushing a portion having a width of the same number as the length of the conical surface along the cutting line.
