Description

  The present invention relates to a carriage mechanism of a processing apparatus, and more particularly to a carriage mechanism of a processing apparatus that performs desired processing on the surface of a medium that is a processing target.

  In this specification, “media” includes various materials such as resin materials such as PVC and polyester as well as various recording media made of paper such as plain paper.

  In the present specification, the width direction of the medium is appropriately referred to as “main scanning direction”, and the longitudinal direction of the medium is appropriately referred to as “sub-scanning direction”. The main scanning direction that is the width direction of the medium and the sub-scanning direction that is the longitudinal direction of the medium are orthogonal to each other.

  2. Description of the Related Art Conventionally, as a processing apparatus, there is known a processing apparatus that uses a cutter pen mounted on a carriage that moves in a main scanning direction with respect to a medium that is transported in a sub-scanning direction by a transporting device.

  In such a processing apparatus, a processing means is mounted on a moving head.

  More specifically, a cutter pen as a processing tool is held by a pen holder included in a carriage, and media is processed by the tip of the cutter pen.

  2. Description of the Related Art Conventionally, a carriage of such a processing apparatus has an elevating mechanism that moves a processing tool up and down by a single solenoid provided in the carriage. However, such a single solenoid has a problem in that there is a limit to the maximum load of the suction force.

  In addition to the single solenoid that moves the processing tool in the vertical direction, there is a processing apparatus that includes a mechanism that assists the lifting mechanism.

  Specifically, for example, according to the technique disclosed in Japanese Utility Model Laid-Open No. 2-14952, which is presented as Patent Document 1, when cutting a medium, the depth of cut can be set in two stages. Therefore, two solenoids are provided.

  More specifically, in Patent Document 1, a first solenoid is provided on the side surface of the cutter, and the force of the first solenoid is transmitted to the processing tool via a lever to lower the processing tool by one step. ing.

  At this time, the depth of the cut for cutting the media is adjusted by adjusting the length by expanding and contracting the spring connected to the upper end of the processing tool.

  The second solenoid arranged on the upper part of the carriage is directly transmitted to the processing tool, and the mechanism further lowers the one-step processing tool.

  As described above, when the suction force of the solenoid is directly transmitted, there is a problem that a stable cutting pressure cannot be obtained because the load is changed by the heat generated from the coil.

  As another example, there is a high-pressure carriage that combines a conventional AC solenoid and a voice coil solenoid. Such a high-pressure carriage includes an AC solenoid iron core, a slider column that serves as an operating part of a processing tool, and adjustment. The mechanical parts for use were integrated with the movable slider itself.

  In such a high-pressure carriage, since many of the necessary mechanisms are connected and integrated on the slider as described above, the weight of the movable slider itself increases.

  As a result, the spring force required to raise the weight of the heavier slider is required, so there are new problems such as a decrease in the maximum cut pressure due to the cut off of the cut pressure on the voice coil solenoid side and a significant decrease in slider lift response. It was something to invite.

  FIG. 1 is a schematic configuration perspective view of an example of a processing apparatus equipped with a carriage mechanism of a processing apparatus according to the present invention.

  The processing apparatus 10 shown in FIG. 1 is a paper move type that performs processing on media using processing means mounted on a carriage that moves in the main scanning direction with respect to the media conveyed in the sub-scanning direction. It is a processing device.

  First, the processing apparatus 10 includes a fixed base member 12 extended in the main scanning direction, and side members 14L and 14R arranged orthogonally to the base member 12 at both left and right ends of the base member 12. The left and right side members 14L and 14R are connected to each other, and have a central wall 16 having a rail for a carriage 20 described later on the wall surface, and extend in the main scanning direction on the front of the central wall 16. A guide rail 18, a rail 20 arranged parallel to the wall surface of the central wall 16 along the main scanning direction, and a carriage 20 slidably mounted on the guide rail 18. And a motor (not shown) for moving the carriage 20 in the main scanning direction.

  Further, the carriage 20 detachably holds a processing tool such as a cutter pen described later. The processing tool is moved up and down by a built-in first lifting mechanism 22 (voice coil solenoid) and moved in a direction (Y direction) orthogonal to the X direction by driving a Y motor (not shown). . Thus, by moving the medium and the carriage 20 relative to each other, a predetermined process can be performed on the medium.

  Such a processing apparatus 10 is provided with an operation panel 24 for inputting a user's desired instruction. The contents of various settings made by operating the operation panel 24 are processed by a built-in microcomputer.

  Further, the contents of various settings are stored in a predetermined area of the memory means as information used for various processes for processing realized by a microcomputer.

  That is, it is configured to receive data from the operation panel 24, various sensors, etc., and to drive and control output devices such as the X motor, Y motor, and the lifting mechanism of the carriage 20 to perform predetermined processing on the media. Yes.

  Next, the configuration of the carriage 20 that holds the cutter pen 26 as a processing tool will be described with reference to FIGS. 2 (a) and 2 (b).

  2 (a) and 2 (b) are enlarged schematic perspective views of essential parts showing the internal structure of the carriage 20 of the processing apparatus 10 according to the present embodiment.

  The carriage 20 has a cutter pen 26 installed so as to be movable in the vertical direction, a voice coil solenoid 22 as a first lifting mechanism as a drive source of the cutter pen 26, and a downward force applied to the cutter pen 26. The assist load leaf spring 30 is applied to the assist load leaf spring 30 and the assist solenoid 32 is a second lifting mechanism serving as a drive source for the assist load leaf spring 30.

  More specifically, first, the skeleton of the carriage 20 includes a substantially L-shaped carriage base 20a serving as a bottom portion and a wall portion 20b serving as a rear surface thereof.

  The carriage base 20a and the wall portion 20b are coupled on the back side of the carriage 20, that is, on the central wall 16 side of the processing apparatus 10.

  A voice coil solenoid 22 is disposed in the vicinity of the center of the bottom upper surface 20aa of the carriage base 20a serving as the skeleton of the carriage 20.

  The voice coil solenoid 22 has a magnet (not shown) on the inner wall portion of the voice coil solenoid 22, and further has a coil 22a that can move in the vertical direction inside the magnet.

  A tool holder 20 c is connected to the coil 22 a of the voice coil solenoid 22.

  Here, the tool holder 20c is a substantially L-shaped member that operates in the vertical direction in conjunction with the coil 22a of the voice coil solenoid 22, and is oriented in the direction facing the carriage base 20a and on the wall 20b. It is arranged along.

  That is, the carriage base 20a and the tool holder 20c are arranged to form a square shape.

  As described above, the tool holder 20c moves in the vertical direction in conjunction with the coil 22a of the voice coil solenoid 22. However, the tool holder 20c extends in the vertical direction and is fixed to the carriage base 20a. Since the slider 20d (described later) disposed and the shaft 20e disposed on the wall 20b along the vertical direction are configured to be fitted, the slider 20d moves up and down.

  Next, the configuration of the tool holder 20c will be described. The tool holder 20c is connected to the coil 22a of the voice coil solenoid 22, the assist load leaf spring 30, which will be described later, and the cutter pen 26. is there. Further, since the tool holder 20c, the assist load leaf spring 30, and the cutter pen 26 are substantially integrated, the tool holder 20c moves in the vertical direction in conjunction with the coil 22a of the voice coil solenoid 22.

  More specifically, a grip portion 20f for gripping the cutter pen 26 is disposed on the side surface of the tool holder 20c.

  The cutter pen 26 is detachably held by such a holding portion 20f.

  Note that the gripping part 20f moves up and down integrally with the tool holder 20c.

  Further, the slider 20d described above is disposed in the gap between the voice coil solenoid 22 and the gripping portion 20f in the tool holder 20c so as to extend in the height direction.

  More specifically, the slider 20d has a lower end fixedly erected on the carriage base 20a, and an upper end fixed to an upper base 20g described later.

  That is, the slider 20d is erected on the carriage base 20a so as to be parallel to the wall portion 20b and to penetrate the tool holder 20c.

  In addition, a hole is formed in the upper surface of the tool holder 20c so that the slider 20d can be disposed.

  Furthermore, the side surface of the tool holder 20c has a cylindrical portion 20h at a position facing the grip portion 20f.

  The cylindrical portion 20h is formed so as to partially surround the slider 20d.

  As described above, the tool holder 20c is configured to move up and down along the rail 20e disposed along the wall portion 20b with the slider 20d as a support shaft.

  Next, the upper base 20g that supports the upper end of the slider 20d will be described. The upper base 20g is disposed in a space immediately above the tool holder 20c with a predetermined gap from the tool holder 20c. This is a planar member.

  The upper base 20g is positioned so as to be closer to the side surface of the gripping part than the center of the carriage 20, and is arranged to be parallel to the bottom upper surface 20aa of the carriage base 20a.

  The upper base 20g is fixedly installed so as not to move up and down.

  The front end portion of the upper base 20g and the lower end portion of the cylindrical portion 20h are stretched by a spring 28 arranged so as to be parallel to the slider 20d. Therefore, a force that biases the cutter pen 26 upward is applied by the spring 28.

  Next, an assist solenoid 32 is provided on the upper surface of the upper base 20g.

As the assist solenoid 32, for example, a butting type AC solenoid or the like can be used.

  The assist solenoid 32 has an iron core 32a protruding downward, and a hole is formed in the upper base 20g so as to be inserted through the iron core 32a.

  Further, an assist load leaf spring 30 is disposed below the iron core 32a of the assist solenoid 32.

  The assist load leaf spring 30 is a plate-like elastic body formed in a substantially T shape, and is distorted by pressing.

  The upper surface of the upper end portion of the assist load leaf spring 30 is disposed so that the lower end portion of the iron core 32a abuts when the assist solenoid 32 is operated.

  Therefore, the assist load leaf spring 30 is screwed at its lower end to the tool holder 20c so that the vicinity of the T-shaped intersection is located directly below the iron core 32a.

Since the assist load leaf spring 30 is locked to the tool holder 20c, when the force is applied from the assist solenoid 32, the assist load leaf spring 30 is distorted according to the pressure. The tool holder 20c is pushed downward in conjunction with the distortion of the spring 30.

  In the above configuration, the operation of the carriage 20 during machining using the machining apparatus 10 according to the present embodiment will be described below with reference to FIG.

  The operation of the processing apparatus 10 including the carriage mechanism 20 of the processing apparatus according to the present invention is a known technique, and thus the description of the entire operation is omitted.

  FIGS. 3A, 3B, and 3C are schematic explanatory views showing the operation status of the carriage 20 during processing, and FIG. 3A shows the state of the carriage 20 before operation. FIGS. 3B and 3C show a state of the carriage 20 in operation.

  First, the carriage 20 of the processing apparatus 10 according to the present embodiment is not operated with the voice coil solenoid 22 and the assist solenoid 32 before the operation, and the cutter pen 26 is positioned at the standby position in the height direction. (See FIG. 3A).

  When the processing apparatus 10 is driven by an instruction from the microcomputer, the carriage 20 moves in the main scanning direction and the sub-scanning direction, and the voice coil solenoid 22 operates.

  When the voice coil solenoid 22 is operated, the coil 22a is attracted downward by the internal magnet, the coil 22a moves downward, and is pressed down to the lowest end.

  The tool holder 20c connected to the coil 22a moves downward as the coil 22a moves (see FIG. 3B).

  For this reason, as shown in FIG. 3B, the position of the cutter pen 26 in the height direction is changed to be positioned at the height a.

  Further, along with the operation of the voice coil solenoid 22, the assist solenoid 32 is also operated.

  When the assist solenoid 32 is operated, the iron core 32a protrudes downward.

  Next, when the iron core 32 a protrudes downward, the lower end of the iron core 32 a comes into contact with the leaf spring 30, and a downward force is applied to the leaf spring 30.

  When a downward force is applied to the leaf spring 30, the end of the leaf spring 30 is pulled downward, and the tool holder 20c connected to the end of the leaf spring 30 is also pulled downward. It is done.

  In this case, more load can be applied to the cutter pen 26 than when only the voice coil solenoid 22 is operating.

When the voice coil solenoid 22 and the assist solenoid 32 stop operating, the cutter 28 is raised by the spring 28.

  As described above, the cutter pen 26 repeatedly moves up and down as the voice coil solenoid 22 and the assist solenoid 32 move.

  As described above, according to the carriage mechanism 20 of the processing apparatus of the present invention, force is applied to the cutter pen 26 in two steps using the voice coil solenoid 22 and the assist solenoid 32. The raising and lowering of the cutter pen 26 can be processed with a stable operation.

  Therefore, according to the machining apparatus 10 including the carriage mechanism 20 of the machining apparatus according to the present invention, the raising / lowering of the processing tool such as the cutter pen is performed in two stages, thereby improving the response speed without affecting the elevation response. It is possible to make it.

Moreover, according to the processing apparatus 10 provided with the carriage mechanism 20 of the processing apparatus according to the present invention, it is possible to stably lift and lower a processing tool such as a cutter pen.

  When the voice coil solenoid 22 is activated, the coil 22a moves downward, is pushed down to the lowest end, and the tool holder 20c connected to the coil 22a moves downward as the coil 22a moves (FIG. 5 ( See b)).

  Then, as shown in FIG. 5 (b), the position of the cutter pen 26 in the height direction is changed, and is lowered from the standby position before operation (see FIG. 5 (a)) to the position of height A.

  Further, when the assist solenoid 32 is operated, the iron core 32 a protrudes downward, the lower end portion of the iron core 32 a comes into contact with the upper end portion of the compression spring 202, and a downward force is applied to the compression spring 202.

  As the downward force is applied to the compression spring 202, the tool holder 20c in which the compression spring 202 is disposed is also pushed downward.

As in the case of the carriage 20 of the processing apparatus 10, the cutter pen 26 is lowered .

  As described above, by using the voice coil solenoid 22 and the assist solenoid 32, the force of the assist solenoid 32 is transmitted to the tool holder 20c via the compression spring 202, and the cutter pen 26 is moved up and down. It ’s good.

By tensioning the spring between the lower surface and the lower surface, the force of the assisting solenoid 32 can be transmitted to the tool holder 20c.

  (3) In the above embodiment, a paper move type processing apparatus is used. However, the present invention is not limited to this, and recording paper is placed on a base having a large area. A so-called flat bed type processing apparatus that is fixedly mounted may be used.

  (4) In the above-described embodiment, the solenoid is used as a means for assisting the raising and lowering of the cutter pen. However, the present invention is not limited to this, and the cutter pen can be driven using a driving means such as a motor. The raising / lowering may be controlled.

Here, FIG. 6 shows an enlarged explanatory view of the main part of the processing apparatus, which has a motor 302, a cam 304, and a spring 306 in the carriage 300 instead of the assist solenoid 32. This is different from the carriage 20 of the processing apparatus 10 described above.

  As shown in FIG. 6, the motor 302 is disposed above the upper base 20g, and is disposed such that the axis at the center thereof is parallel to the sub-scanning direction.

  An elliptical cam 304 is connected to the tip of the central axis of the motor 302. Further, the cam 304 comes into contact with the shaft end portion 307a of the shaft 307 urged upward by the spring 306 to the lower side of the cam 304 by the rotation of the motor, and the shaft 307 can be moved up and down.
