Description

  The present invention relates to a head mechanism, and more particularly, to data relating to creation of an image such as image density data representing image density (hereinafter referred to as image density data representing image density). Various data are collectively referred to simply as “image data.”) By pressing the processing tool against the processing surface of the workpiece, the processing surface is stamped to form a recess, In addition to forming an image formed by the recesses formed by the stamping on the surface to be processed (hereinafter, “image formed by the recesses generated by the stamping” is appropriately referred to as “the stamped image”), Two head devices (for example, in the above-described embossing and cutting device, an embossing head for performing engraving and a clipping device). Cormorants and the cutting head is two heads apparatus having a different function, respectively. Head portion about the head mechanism in apparatus composed of a).

  2. Description of the Related Art Conventionally, as a device that presses a processing tool against a processing surface of a workpiece based on image data and forms various stamped images such as characters, figures, or symbols on the processing surface, for example, Patent Literature A stamping machine as disclosed in No. 1 is known.

  Such a stamping machine is configured, for example, such that a machining tool is provided at a lower portion of a plunger provided so as to pass through a solenoid, and when the solenoid is energized, the plunger is sucked and the machining tool is lowered.

  As the machining tool descends, the machining tool abuts the work surface of the work piece and presses the work surface, thereby stamping the work surface to form a recess and striking the work surface. An engraved image is formed.

  At this time, if the energization time to the solenoid is changed according to the image data, the intensity of the pressing force applied to the work surface by the processing tool changes, and the shape changes according to the intensity change of the pressing force. Since the recessed portion thus formed can be formed on the workpiece, a desired stamped image can be formed on the workpiece surface of the workpiece.

  In such an engraving machine, when an engraved image formed on a workpiece is to be cut out in a desired area, a manual cutting operation using a cutter or the like by an operator, or an engraving machine is separate. It was necessary to prepare a dedicated cutting machine and to perform a cutting operation using the cutting machine.

  For this reason, conventionally, when a stamped image formed by a stamping machine is cut out in a desired area and commercialized, the labor cost of an operator and the cost of introducing a cutting machine are incurred. At the same time, when a cutting machine is introduced, a place for arranging the cutting machine is required, and there is a problem that a large arrangement space must be taken.

As a technique for solving such problems, a stamping and cutting device as disclosed in Patent Document 2 is known.

  In the stamping and cutting device disclosed in Patent Document 2, a stamping head for creating a stamped image and a cutting head for cutting out the contour of the stamped image are mounted on one guide rail.

  Further, the cutting head and the cutting head are connected by a connecting portion constituted by a magnet or the like, and an engagement hook provided on the cutting head is provided on a side member of the cutting and cutting device. It is configured to be separated by engaging with a hook, and to be controlled for movement by the same driving device.

  When a desired stamped image is created based on image data from the host computer, the cutting head and the stamping head are connected and moved by moving the cutting head. The head is moved to form a stamped image.

  In addition, when performing an image cropping operation based on image data, the cutting head and the cutting head are separated, the cutting head is fixed to the side member, and only the cutting head is driven to drive the cutting image. The contour is cut out.

  For this reason, in the stamping and cutting device disclosed in Patent Document 2, it becomes possible to form a stamped image and cut out a desired region with a single device, thereby suppressing an increase in cost. In addition, it is not necessary to take a large arrangement space.

However, in the stamping and cutting device disclosed in Patent Document 2, when a stamped image is formed, the stamping head and the cutting head are integrally connected by the connecting portion, and the movement is controlled by the driving device. The

  For this reason, when it is arranged on the guide rail, the head part in which the embossing head and the cutting head are integrated becomes larger in the width direction (sub-scanning direction in which the head part moves), and the head part When moving in the sub-scanning direction, a large inertia is generated in the head portion.

  For this reason, in addition to simply reducing the size of the head device such as the stamping head and cutting head in the head, it is desirable to propose a head configuration that reduces the size in the width direction as much as possible. It was rare.

Here, the head portion composed of the embossing head and the cutting head is simply provided close to the embossing head and the cutting head without adopting a configuration in which the embossing head and the cutting head are coupled by the coupling portion. Thus, a technique for reducing the size has been proposed (described in a modification of Patent Document 2).

  However, in such a case, it is necessary to provide a space between the embossing head and the cutting head so that at least an operator can change his / her hand and change the tool attached to the embossing head and the cutting head. Therefore, it is difficult to downsize the head portion to a certain size or less in the width direction.

  Therefore, a proposal of a mechanism capable of providing a space around the two head devices in a head portion in which two head devices having different functions such as a marking head and a cutting head are disposed in proximity to each other. Was desired.

  The stamping head 30 is provided with a locking portion 40 on the upper side of the right side surface and a lever 42 on the right side surface 40 a of the locking portion 40.

  The locking part 40 has a recessed part 40c on the upper side in the vicinity of the rear end part 40b.

  Further, the lever 42 is provided with a convex portion 42a provided to protrude rightward on the upper side of the front side, and a convex portion 42c provided to protrude rearward at the rear end portion 42b. (See FIGS. 5A and 5B).

  The convex portion 42c is located on the rear side of the concave portion 40c of the engaging portion 40 with the rear end surface 42ca adjacent thereto, and the upper end portion 42cb thereof is the same as or slightly lower in the height direction with the lower end portion 40ca of the concave portion 40c. It arrange | positions so that it may be located in.

  The lever 42 is connected to the right side surface 40a of the locking portion 40 by a shaft 46. When the convex portion 42 is pressed downward by the operator, the lever 42 rotates by a predetermined amount about the shaft 46 as a central axis. The upper end portion 42cb of the convex portion 42c is positioned above the upper end portion 40cb of the concave portion 40c.

  Further, the head portion 10 is formed by the carriage 28, the marking head 30, and the cutting head 32.

  In the head portion 10, a hook 44 is provided on the upper end surface 28 c of the carriage 28.

  The hook 44 includes a standing portion 44-1 erected from the upper end surface 28c of the carriage 28, a substantially rectangular plate spring 44-2 disposed on the upper side of the erected portion 44-1, and a standing portion. A hook portion 44-3 is disposed below the portion 44-1 so as to be rotatable about a shaft 48 as a central axis, and is biased downward by a leaf spring 44-2 (FIG. 4 ( a) See (b)).

  In the head unit 10, a stamping head 30 is rotatably provided at a left end 28 a of the carriage 28, and a cutting head 32 is fixedly provided on the right side of the carriage 28. Yes.

  That is, the marking head 30 is connected to the left side end portion 28a of the carriage 28 by a hinge 38 provided at the left side end portion 28a of the carriage 28, and a shaft 38a extending in the height direction is connected to the stamping head 30. A carriage 28 is rotatably disposed as a central axis.

  The stamping head 30 is fixed to the carriage 28 by engaging the hook portion 44-3 of the hook 44 with the concave portion 40c of the locking portion 40.

  That is, in the head unit 10, the embossing head 30 is fixed to the carriage 28 by the lock mechanism including the locking portion 40, the lever 42 and the hook 44, or the embossing head 30 is rotated with respect to the carriage 28. It is possible to do.

  That is, the head unit 10 is in a state where the cutting head 30 is fixed to the carriage 28 when the machining tool 34 attached to the cutting head 30 is replaced (the state shown in FIG. 3A). Then, the engagement state between the locking portion 40 and the hook 44 is released by the operator by the lever 42, and the stamping head 30 is rotated by rotating in the direction of arrow A about the shaft 38a as the central axis. (The state shown in FIGS. 3B and 4A and 4B).

  Further, when the head unit 10 actually uses the stamping and cutting device 100, the head unit 10 is rotated (in the state shown in FIGS. 3B, 4A, and 4B). Therefore, the operator rotates the shaft 38a in the direction of the arrow B around the shaft 38a as the center axis, and the locking portion 40 and the hook 44 are engaged, and the stamping head 30 is fixed to the carriage 28. (The state shown in FIG. 3A).

In the above configuration, the case where the cutting head 30 is rotated in the head unit 10 and the case where the cutting head 30 is fixed to the carriage 28 will be described.

  First, when the embossing head 30 is rotated in the head portion 10, the operator presses the convex portion 42a of the lever 42 downward (see FIG. 6A). The convex portion 42c of the lever 42 is pushed upward (see FIG. 6B).

  Then, the convex portion 42c is pushed upward, so that the hook portion 44-3 rotates in the direction of arrow C about the shaft 48 against the urging force of the leaf spring 44-2 (FIG. 6C). To see.)

  At this time, the tip portion 44-3a of the hook portion 44-3 rotated by the convex portion 42c comes to be positioned above the upper end portion 40cb of the concave portion 40c, and the engagement between the concave portion 40c and the hook portion 44-3. The state is released (see FIG. 6D).

  Then, in a state where the engagement state between the concave portion 40c and the hook portion 44-3 is released, the operator rotates the embossing head 30 in the direction of arrow D to rotate the embossing head 30 ( Reference is made to FIG.

  In this way, the operator performs a predetermined operation such as replacing the machining tool 34 attached to the embossing head 30 while the embossing head 30 is rotated.

Next, a case where the embossing head 30 is fixed to the carriage 28 in the head unit 10 will be described.

  First, when the embossing head 30 is rotated, in the hook 44, the hook portion 44-3 rotates in the direction of the arrow E with the shaft 48 as the center axis by the urging force of the leaf spring 44-2, and the tip portion 44. -3a is in contact with the standing portion 44-1 (see FIGS. 7A and 7B).

  Then, after the operator moves the embossing head 30 in the direction of arrow F and presses the locking portion 40 against the hook 44 (see FIGS. 7C and 7D), the embossing head 30 is moved. Further, the locking portion 40 is pushed into the hook 44 by moving in the arrow F direction.

  At this time, the hook portion 44-3 is pushed upward by the inclined portion 40ba above the rear end portion 40b of the locking portion 40 against the urging force of the leaf spring 44-2.

  Then, the tip portion 44-3a of the hook portion 44-3 pushed upward falls into the concave portion 40c of the locking portion 40, and the hook portion 44-3 urged downward by the leaf spring 44-2. The recessed portion 40c is engaged (see FIG. 7E).

  Thus, when the embossing head 30 is fixed to the carriage 28, the operator operates the host computer and the operation panel 20 to move the head unit 10 in the main scanning direction in the embossing and cutting device 100, and the sheet 12. Moves in the sub-scanning direction to form a stamped image, and the formed stamped image is cut out in a predetermined area.

As described above, the head unit 10 includes the embossing head 30 that is rotatable at the left end portion 28a of the carriage 28 by the hinge 38 having the axis 38a as the center axis. The cutting head 32 is disposed on the right side of the carriage 28 so as to be close to the head 30.

  For this reason, in the head part 10, compared with the head part (refer FIG. 8 (a)) which consists of the cutting head and cutting head by the prior art which are indicated by patent document 2, it stamps. Since there is no need to provide a connecting portion for connecting the head and the cutting head and a locking portion for separating the embossing head and the cutting head, the size is reduced in the width direction (see FIG. 8). .)

  Further, in the head unit 10, the stamping head 30 rotates about the shaft 38 a as a central axis, so that a space can be created around the stamping head 30 and the cutting head 32.

  For this reason, in the head part 10, it becomes possible to arrange | position the cutting head 32 so that it may adjoin to the cutting head 30, and it becomes possible to reduce the size of the head part 10. FIG.

  Furthermore, in the head part 10, since the stamping head 30 rotates to the left side, a space can be created on the right side and the back surface of the stamping head 30, not only the replacement of the processing tool 34, Even when maintenance of the stamping head 30 is performed, the stamping head 30 can be inspected from a desired surface.

The above-described embodiment can be modified as shown in the following (1) to (6).

  (1) In the above-described embodiment, the stamping and cutting device 100 including the head unit 10 in which the stamping head 30 and the cutting head 32 are disposed has been described. Of course, the present invention is not applied only to the head portion 10 of the engraving and cutting apparatus 100.

  In addition, the marking head 30 is rotatably arranged by a hinge 38 at the left side end portion 28 a of the carriage 28, and the cutting head 32 is rotatably arranged by a hinge 50 at the right side end portion 28 b of the carriage 28. You may make it install (refer FIG.9 (c)).

  In this case, the locking mechanism described in the above embodiment is disposed on the right side surface of the embossing head 30 and the upper end surface 28c of the carriage 28, and the left side of the cutting head 32 and the upper side of the carriage 28 are disposed. The end face 28c is provided with a lock mechanism that is symmetrical with the lock mechanism.

  (3) In the above-described embodiment, the stamping head 30 is rotatably disposed at the left end 28a of the carriage 28 by the hinge 38 having the shaft 38a extending in the height direction. However, it is needless to say that the present invention is not limited to this.

  That is, the structure is such that the stamping head 30 is rotatably arranged by a hinge 52 having a shaft 52a extending in the width direction at the upper left side of the carriage 28, and the stamping head 30 is pulled up to the front side. (Refer to FIGS. 10A and 10B).

  In this case, when combined with the modification (2), the cutting head is rotatably arranged by the hinge 54 in which the shaft 54a extends in the width direction at the upper right side of the carriage 28. The configuration is such that 32 is pulled forward (see FIGS. 10C and 10D).

  Further, the stamping head 30 is rotatably disposed by a hinge 52 having a shaft 52a extending in the width direction at the upper left side of the carriage 28, and the shaft 54a is disposed in the width direction at the upper right side of the carriage 28.
