Embodiment 1 FIG.
1 is a front view showing a laser processing apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a plan view showing the apparatus of FIG. In the figure, 1 is a laser processing apparatus main body for performing laser processing on a workpiece 10, 2 is a carry-in portion for an operator to prepare the workpiece 10 to be processed, 3 is a carriage for storing the workpiece 10 before processing, This is a positioning unit for previously positioning the workpiece 10 before processing.

  5 is an unloading unit for unloading the workpiece 10 after processing, 6 is a cart for storing the unloaded workpiece 10, 7 is a loader for conveying the workpiece 10 from the cart 3 of the loading unit 2, and 8 is unloading from the laser processing apparatus main body 1. An unloader that transports the workpiece 10 to the section 5, 9A is a defective product discharging section that receives the defective workpiece 10, and 21 is a workpiece reversing device that reverses the workpiece 10.

  Next, the overall operation will be described. 3 is a configuration diagram schematically showing the arrangement state of the apparatus of FIG. 1, FIG. 4 is an explanatory diagram showing the work flow of the apparatus of FIG. 3, and FIG. 5 is a time chart showing the work flow of FIG. The workpieces 10 housed in the carriage 3 of the carry-in unit 2 are transported and positioned one by one by the loader 7 to the positioning unit 4 and then transported to the laser processing apparatus main body 1.

  In the laser processing apparatus main body 1, a reference mark provided in advance on the workpiece 10 is detected by a detection unit (not shown), and laser processing is performed only on a normal workpiece 10. The workpieces 10 of different types or defects are conveyed to the defective product discharge unit 9A by the unloader 8 without laser processing. The normal workpiece 10 after laser processing is conveyed to the workpiece reversing device (reversing machine) 21 by the unloader 8 and is reversed 180 degrees there.

  The inverted workpiece 10 is conveyed by the unloader 8 and stored in the carriage 6. When all the workpieces 10 in the carriage 3 are thus laser-processed and stored in the carriage 6 in an inverted state, the empty carriage 3 in the carry-in section 2 and the carriage 6 in the carry-out section 5 are replaced. Then, laser processing is performed on the back surface in the same manner as the front surface.

  In such a laser processing apparatus, when the laser processing is performed on both surfaces of the workpiece 10, the workpiece 10 is automatically inverted, so that the inversion work is not required and the working efficiency is improved.

  6 to 10 are perspective views showing the work reversing device 21 of FIG. 1 in the order of operation, and FIGS. 11 to 16 are side views showing the work reversing device 21 of FIG. 1 in the order of operation. In the figure, reference numerals 22 and 23 denote first and second tables which can reciprocate between a clamping position facing each other and a delivery position at which a workpiece is delivered to the workpiece processing apparatus body 1, and 24 is a first table. The rotating mechanism rotates the first and second tables 22 and 23 by 180 degrees with the workpiece 10 sandwiched between the second tables 22 and 23 and reverses the workpiece 10.

It is a rodless cylinder as a table driving mechanism for reciprocating the tables 22 and 23 in the horizontal direction between the clamping position and the delivery position.

  Next, the operation of the work reversing device 21 will be described. When the workpiece is received, the first table 22 is driven by the rodless cylinder 27 and moved to the delivery position as shown in FIGS. The workpiece 10 after the laser processing is transported by the suction unit 8a of the unloader 8 and placed on the first table 22 at the delivery position. Thereafter, the suction of the workpiece 10 by the suction unit 8a is released, and the suction unit 8a is moved to the standby position.

  Thereafter, as shown in FIGS. 8 and 12, the first table 22 is returned to the clamping position by the rodless cylinder 27. Thereby, when the workpiece 10 is received between the first and second tables 22 and 23, the workpiece 10 is clamped by the clamping mechanism 25 as shown in FIG. In this state, the rotation mechanism 24 is driven, and as shown in FIGS. 9 and 14, the first and second tables 22 and 23 are rotated 180 degrees, and the sandwiched work 10 is reversed.

Thereafter, the workpiece 10 on the second table 23 is sucked by the suction unit 8 a and is transported by the unloader 8 to the cart 6 of the unloading unit 5.

  In such a work reversing device 21, since the entire work 10 is reversed while being sandwiched between the first and second tables 22 and 23, the sheet-like work 10 having a thin plate thickness and a weak waist is handled. Even in such a case, the work 10 does not bend and fall, and even if the size of the work 10 is changed, adjustment is not required, and adjustment work is not required. Further, since the workpiece 10 is clamped by the clamping mechanism 25, the positional deviation of the workpiece 10 before and after reversal is prevented.

  Further, since the work 10 is delivered by horizontally projecting the first and second tables 22 and 23 to the delivery position, as shown in FIG. 1, a defective product discharger 9A is provided below the delivery position. Can be arranged. That is, the defective workpiece is conveyed to the defective product discharge unit 9A by the unloader 8 when both the first and second tables 22 and 23 are in the clamping position. For this reason, the workpiece 10 after laser processing and the defective workpiece are not overlapped, and it is easy to eliminate the defective workpiece, and damage to the normal workpiece 10 is prevented.
