The transport unit 150 is provided with a manipulator (not shown) that is driven by a motor (not shown). The workpieces 510 and 520 are conveyed from the conveyance unit 150 to the support bases 410 and 420 by such a manipulator.

  When the prior art processing apparatus 100 as shown in FIGS. 5A and 5B is driven, the processing unit main bodies 220 and 320 are moved by the drive motors 250 and 350 connected to the horizontal support units 210 and 310, respectively. The machining heads 240 and 340 are moved in the vertical direction by drive motors 260 and 360 that are slid in the horizontal direction and connected to the vertical support portions 230 and 330, respectively. Thus, the two workpieces 510 and 520 are machined simultaneously while adjusting the cut length and the cut depth for each of the machining heads 240 and 340.

  However, in the processing apparatus 100 of the prior art, at least four drive motors 250, 350, 260, 360 are required to adjust the cutting length and the cutting depth of the processing heads 240, 340. Furthermore, although not shown in the drawings, another manipulator is also required for the manipulator of the conveyance unit 150, so that the number of driving motors required for the entire processing apparatus 100 is further increased.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following drawings, the same members are denoted by the same reference numerals. In order to facilitate understanding, the scales of these drawings are appropriately changed.
FIG. 1 (a) is a side view of a processing apparatus according to the present invention, and FIG. 1 (b) is a top view of the processing apparatus according to the present invention. As shown in these drawings, the base 11 of the processing apparatus 10 is provided with a processing unit 20. The processing portion 20 includes a horizontal support portion 21 supported by the base surface 12 of the base 11 and a processing portion main body 22 that slides on the horizontal support portion 21 in the horizontal direction. As can be seen from FIG. 1B, the first vertical support portion 23 and the second vertical support portion 33 have a predetermined distance on the vertical surface 29 of the processing portion main body 22 perpendicular to the base surface 12. They are provided in parallel with each other. Further, a machining head 24 for machining, for example, grinding the workpiece is provided at the tip of the shaft extending from the lower end of the vertical support portion 23. Although not shown in the drawing, it is assumed that the vertical support portion 33 is similarly provided with a machining head 34. These processing heads 24 and 34 are, for example, rotating blades, but processing heads 24 and 34 having other configurations may be employed.

  As can be seen from FIG. 1A and FIG. 1B, a drive motor 25 that slides the processing portion main body 22 along the base surface 12 is connected to the horizontal support portion 21. Further, drive motors 26 and 36 for moving the shafts of the machining heads 24 and 34 perpendicularly to the base surface 12 are connected to the vertical support portions 23 and 33, respectively.

  Therefore, in the present invention, when it is required to move the machining heads 24 and 34 in the horizontal direction (X direction), the drive motor 25 slides the machining unit body 22 along the base surface 12 of the base 11. Move. Since the processing heads 24 and 34 are integrally assembled with the processing unit main body 22, the processing heads 24 and 34 are indirectly moved in the horizontal direction by the drive motor 25. That is, in the present invention, the single drive motor 25 serves to move both the machining heads 24 and 34 in the horizontal direction.

  On the other hand, when it is required to move the machining heads 24 and 34 in the vertical direction (Y direction), the machining heads 24 and 34 may be moved up and down directly by the drive motors 26 and 36. Although not shown in the drawings, instead of providing the dedicated drive motors 26 and 36 for the machining heads 24 and 34, the machining heads 24 and 34 are integrally moved up and down by a single drive motor. Also good.

  Further, in FIG. 1B, a conveyance unit 60 that conveys the workpiece 51 is disposed on the base surface 12 in front of the machining heads 24 and 34. The transport unit 60 includes a rotating body 61 that is rotated in the direction of the arrow by a drive motor 65, and the rotating body 61 is provided with a rotating disk 62 that rotates concentrically. As shown in the drawing, a plurality of holding portions 70 that hold the workpiece 51 are provided on the upper surface 63 of the rotating disk 62.

  In the embodiment shown in FIG. 1B, eight holding portions 70, each of which is a substantially L-shaped member, are arranged at equal intervals in the circumferential direction of the rotating disk 62. Each of these holding portions 70 is arranged with the apex facing inward. Accordingly, the angle α formed by each of the elongated portions constituting the L-shaped holding portion 70 and the radius of the rotating disk 62 is 45 °.

  In the illustrated embodiment, the rotating disk 62 is rotated once by eight index rotations (indexing rotations). Specifically, the shaft portion of the rotating body portion 61 has a substantially octagonal prism structure, and when this shaft portion rotates once in the corresponding substantially octagonal column type casing, the shaft portion is a substantially octagonal column type casing. And the rotating body 61 can be fixed at that position. These engagement positions correspond to the positions of the plurality of holding portions 70 shown in FIG. Therefore, in the present invention, the workpiece on the holding unit 70 can be easily and accurately positioned at a position corresponding to the processing heads 24 and 34 simply by rotating the transport unit 60. As a matter of course, the number of holding portions 70 other than eight may be provided on the rotating disk 62.

  2A, 2B, and 2C are a top view, an end view, and another end view showing a state in which the workpiece is held by the holding portion, respectively. As shown in FIG. 2A, each holding portion 70 includes two elongated portions 71 and 72 arranged so as to be orthogonal to each other at a vertex portion 80 having a substantially cubic shape. The elongated portion 71 is located on the upstream side in the rotation direction of the transport unit 60 (see FIG. 1B), and the elongated portion 72 is located on the downstream side in the rotational direction. On the upper surfaces of the elongated portions 71 and 72, notched surfaces 73 and 74 that are notched so as to face other adjacent holding portions 70 are formed. As can be seen from FIG. 2A to FIG. 2C, these notch surfaces 73 and 74 are inclined by about 45 ° with respect to the upper surface 63 of the rotating disk 62.

  As shown in the figure, quadrangular columnar workpieces 51a and 51b are provided on the cut-out surfaces 73 and 74, respectively. That is, in this invention, it is set as the structure by which the two to-be-processed objects 51a and 51b are installed with respect to the one holding | maintenance part 70. FIG. And the phase of the to-be-processed objects 51a and 51b installed in the notch surfaces 73 and 74 has shifted | deviated about 90 degrees mutually.

  By the way, in the processing apparatus 10 of the present invention, the workpiece 51 (the workpieces 51a and 51b) is machined as follows. 3 (a), 3 (b) and 3 (c) are a top view, an end view and a side view, respectively, showing the workpiece 51 after machining. As can be seen from these drawings, the workpiece 51 is ground by the same length at a part of two opposing long edges of the upper surface 59 thereof. Therefore, two inclined surfaces 52 and 53 whose phases are shifted from each other by about 90 ° are formed on the workpiece 51 after machining.

  Hereinafter, machining using the processing apparatus 10 of the present invention will be described. First, as described with reference to FIGS. 2A to 2C, the workpiece 51 is installed on the cut surfaces 73 and 74 of the plurality of holding portions 70 of the rotating disk 62, respectively. At this time, as can be seen from FIG. 1B, the elongated portion 71 of the holding portion 70a and another holding portion 70b adjacent to each other with one holding portion 70 spaced from the holding portion 70a in the rotation direction of the rotary body 61. The elongated portion 72 is positioned in a straight line. In other words, at this time, the elongated portion 72 of the holding portion 70a and the elongated portion 71 of the holding portion 70b are positioned in parallel to each other.

  Then, the rotating body 61 is rotated to a desired position as shown in FIG. In the present invention, since the indexing rotatable transport unit 60 is employed, the elongated portion 72 of the holding portion 70a and the elongated portion 71 of the holding portion 70b correspond to the vertical support portion 33 and the vertical support portion 23. Can be easily positioned.

  Next, the drive motors 26 and 36 of the vertical support portions 23 and 33 are driven to lower the machining heads 24 and 34. Thereby, the cutting depth D with respect to each to-be-processed object 51 becomes settled (refer FIG.3 (b)). In other words, in the present invention, the cutting depth D can be controlled by adjusting the movement distances of the machining heads 24 and 34 by the drive motors 26 and 36. Note that the lowest lowered positions of the machining heads 24 and 34 are positions corresponding to the upper surfaces of the elongated portions 71 and 72 of the holding unit 70, for example, the upper surface 72c shown in FIG. The heads 24 and 34 are lowered to the lowest lowered position.

  Thereafter, the drive motor 25 of the horizontal support unit 21 is driven to slide the processing unit main body 22 relative to the horizontal support unit 21, thereby causing the processing unit main body 22 to approach the transport unit 60. As can be seen from FIG. 4, one upper edge portion 51 c of the workpiece 51 b installed on the elongated portion 72 of the holding portion 70 a protrudes from a surface k that contacts the upper surface 72 c of the elongated portion 72. Although not shown in the drawing, it is assumed that the upper edge portion of the workpiece 51a installed in the elongated portion 71 of the holding portion 70b also protrudes in the same manner.

  Therefore, when the processing unit main body 22 is brought close to the transport unit 60, the processing head 34 moves in a direction penetrating the paper surface of FIG. 4, and thereby the upper edge portion 51c is ground. In the present invention, since both the processing heads 24 and 34 are provided in the processing unit main body 22, when the processing head 34 is ground, the processing head 24 is ground in the same manner as the upper edge of the workpiece 51a of the holding unit 70b. Process. This is because the elongated portion 72 of the holding portion 70a and the elongated portion 71 of the holding portion 70b are positioned in parallel with each other on the conveyance portion 60 that can be accurately index rotated with respect to the processing heads 24 and 34. Is also possible. That is, in the processing apparatus 10 of the present invention, two workpieces 51 can be ground simultaneously by a single operation in which the processing unit main body 22 approaches the transport unit 60 by the drive motor 25.

  In the present invention, the moving distance by which the processing portion main body 22 moves from the end surface 55 of the workpiece 51 toward the opposite end surface 58 corresponds to the cut length L of the workpiece 51 (FIG. 3A). See). That is, in the present invention, the cutting length L can be controlled by adjusting the moving distance of the processing portion main body 22 by the drive motor 25. After the predetermined cut length L is obtained, the machining heads 24 and 34 are raised by reversely rotating the drive motors 26 and 36 of the vertical support portions 23 and 33. Next, the processing unit main body 22 is returned to the initial position by the drive motor 25.

  Thereafter, the rotary body 61 of the transport unit 60 is index-rotated only once in the direction of the arrow, and the other holding parts 70c and 70d adjacent to the holding parts 70a and 70b are positioned at the grinding position, and the holding parts 70c and 70d The workpiece 51 is ground in the same manner as described above.

  By repeating this operation, the workpieces 51 on all the holding portions 70 are sequentially ground. As described above, in the present invention, the first and second machining heads 24 and 34 are integrally slid by the single drive motor 25. Therefore, even when the same conveying unit as that in the conventional technique is used, the number of drive motors required in the processing unit 20 of the processing apparatus 10 can be reduced as compared with the conventional processing apparatus. Therefore, in the present invention, it is possible to simplify the configuration of the processing apparatus and reduce the manufacturing cost, and also reduce the power consumption required for use.
