[0027]

Next, the operation of the chip processing apparatus according to the embodiment thus constructed will be described together with the overall operation of the automatic perforation system incorporating the same.

When the system is started, the carriage 15 of the article carry-in device A moves to the article take-out position above the carry-in pallet carriage 10 and is mounted on the moving table 16 located above the front splicing plate 11. The holding body that has been pushed down. Then, after the uppermost attachment plate 11 is magnetically attracted to the holder, the carriage 15 is lifted to raise the attachment plate 11, and the carriage 15 is positioned at the article receiving position. It is moved to the article delivery position above the cart 25. Then, the holding body is lowered again to release the magnetic attraction of the attachment plate 11, so that the attachment plate 11 is transferred to an appropriate position of the support device 19 in the carry-in carriage 25.

When one splicing plate 11 is transferred to the supporting device 19, the first positioning device 20 and the second positioning device 21 are operated in a predetermined order, and the X- Positioning in the Y direction is performed. That is, every time one attachment plate 11 is transferred to the supporting device 19, the attachment plate 11 is transferred.
By repeating the cycle of positioning in the XY direction, a predetermined number of the splicing plates 11 are stacked on the supporting device 19 in a positioned state.

In the same manner as described above, the article carrying-in device A to the article automatic positioning device B from the carry-in pallet trolley 10 are used.
Each time the splicing plate 11 is transferred to the rear side of the support device 19 in the first positioning device 20 and the second positioning device 21.
To position the contact plate 11 in the XY directions. As a result, in the article automatic positioning device B, a plurality of splicing plates 11 are respectively stacked at two positions before and after being separated in the X direction.

In the article automatic positioning apparatus B which has completed the positioning of the splicing plate 11, the drive motor is rotated,
The carrying cart 18 is moved toward the article automatic punching device C along the transfer rails 17, 17 and is positioned at the article delivery position. At this time, the attachment plate 1 on the carriage 18 for loading
One corner of 1 coincides with the reference point of the punch 22. In this state, both holding means 2 of the article holding device 23
4, 24 are actuated to grip both ends of the splicing plate 11 in the Y direction, so that the splicing plate 11 is delivered from the carrying cart 18 to the article holding device 23 and held there. In the punching machine 22, the movement of the drill is controlled on the basis of preset punching position data, and a drilling process is performed on each splicing plate group held by the article holding device 23.

Splicing plate 11 by the above-mentioned automatic article punching device C
When the boring process is completed, the carry-out carriage 25 arrives at the article receiving position, the holding by the article holding device 23 is released, and the base 29 of the carry-out carriage 25 is moved up and down, whereby the attachment plate 11 is delivered on the support member group. After the carry-out carriage 25 has moved to the chip processing position, the tilting cylinder 35 is biased to tilt the table 31 from the horizontal posture to the tilted posture, as shown in FIG. At this time, the splicing plate 11 is also inclined at a predetermined angle, and most of the chips adhering to the upper surface of the splicing plate 11 slide off the slanting upper surface of the splicing plate and are collected by the chute.

Further, the actuation cylinders 45 of the air blowing devices 26 are biased to tilt the frame-like frame 39 from the retracted posture to the actuated posture, whereby the supply pipes 40
The nozzle 41 disposed at the position of the nozzle 41 approaches the upper surface of the inclined contact plate 11. In this state, by supplying air to each supply pipe 40, the air is blown from each nozzle 41 to the upper surface of the splicing plate, and the chips remaining on the upper surface are blown away by the air and removed. It At this time, the chips that are caught in the perforated through hole or at the upper end are also reliably removed by the force of the air, and are collected in the chute.

That is, since the chips adhering to the surface of the splicing plate 11 are reliably removed, the transportation of the splicing plate 11 to the subsequent process is not hindered. Moreover, since the cutting chips can be automatically removed from the attachment plate 11, the worker can be freed from heavy labor in a bad environment, and the production efficiency can be dramatically improved.

After the above-mentioned chip removing work is completed, the tilting cylinder 35 is reversely biased to return the table 31 to the horizontal posture, and the working cylinder 45 is reversely biased to form the frame-like frame. 39 is returned to the retracted position. Then
The attachment plate 11 on the table 31 is transferred to the unloading pallet truck 12 via the article unloading device E.

[0036]

[Modifications] The chip processing method and apparatus according to the present invention are not limited to the above-described embodiments, and various modifications described below can be adopted, for example. During the chip removing process, the table, the frame-shaped frame, or both are oscillated within a predetermined range by the forward and reverse urging of corresponding cylinders to change the air blowing angle with respect to the upper surface of the contact plate. In this case, the chips adhering to the splicing plate can be removed more reliably. The supply pipe or the nozzle may be swung with respect to the frame. The air may be sprayed intermittently. The supply pipe may be configured to be movable in the vertical or horizontal direction with respect to the frame, and air may be blown from the nozzle to the contact plate while moving the supply pipe. The chips can be blown off efficiently. At this time, the table can be swung. Furthermore,
By making the air spray fine and intermittent, it becomes possible to more efficiently blow the chips. The swinging means for swinging the table or the frame may be constituted by a motor, a cam, a link mechanism and the like which are provided separately from the cylinder for tilting the member. Further, the tilting means for tilting the table is not limited to the cylinder of the embodiment, and a means using a motor and a cam, a link mechanism or the like, or other means can be appropriately adopted. Further, the frame-shaped frame may be fixedly arranged in an inclined operating posture as long as it does not hinder the carrying-out of the splicing plate from the table. Although the nozzle is provided in the supply pipe in the embodiment, the supply pipe may be provided with only the outlet.

In the embodiment, the table is tiltably arranged on the carry-out carriage that conveys the splicing plate from the automatic article punching device to the chip processing position. However, a transfer device similar to the article carry-in device is used for automatic article punching. It is possible to arrange the device between the device and the chip processing device, and transfer the attachment plate to a table that is tiltably arranged at the chip processing position to perform the chip removal process. Further, the number of attachment plates placed on the table is not limited to a plurality, and it may be one, or may not be placed in a plurality of rows in the X direction.

[0038]

As described above, according to the chip treatment method and apparatus of the present invention, the chips adhering to the surface of the article can be automatically and surely and efficiently removed.
That is, the worker can be relieved from heavy labor in a bad environment, and automation can be achieved to dramatically improve the production efficiency.
