Description

Detailed Description of the Invention [Field of Industrial Application] The present invention is a method for processing plate materials from a pre-process to a post-process between two processes in the field of processing plate materials of regular length or irregular length with a constant width, including metals and non-metals. The present invention relates to a sheet material stocker for transferring, and in particular to an automatic rapid-forwarding mechanism for sheet materials.

For example, processing of board materials (workpieces) such as printed boards generally requires multiple processes, and processing equipment such as processing machines and inspection equipment are arranged for each process to form a processing line. The plates are sequentially transferred to the device and processed. The processing time of each process equipment often varies due to changes in the length, thickness, etc. of the board material, or differences in the processing capacity of the equipment itself. In order to smoothly transfer the plate material in response to fluctuations in the processing equipment of the pre- and post-process equipment, it is important to rapidly transport the received plate material to the delivery side at a speed greater than the processing line speed.

[Conventional technology]

FIG. 5 is a schematic side view for explaining a conventional plate stocker. In the figure, an endless conveyor chain 3 is stretched between two pulleys 1 and 2 that are spaced apart. A large number of plate holders 4 are arranged and fixed on the conveyor chain 3 at predetermined intervals. The plate material holder 4 has a plate material (for example,
A receiving groove 4a for receiving and holding a printed board 7 is formed. Conveyor chain 3 is
When the pulley 2 is rotationally driven by the motor 5, it is driven to revolve between the pulleys 1 and 2 together with the holder 4 in the directions of arrows A and B. The plate material 7 is transported in the direction of arrow _A1 to the receiving section 6 by a carry-in path 9-1 consisting of rollers, and then continues into the receiving groove 4 of the waiting plate material holder 4 in the receiving section 6.
The leading end side is fitted into the inside a and held by the plate material holder 4, and is transferred by the conveyor chain 3 to the dispensing section 8 side (in the direction of arrow A). Then, the plate material 7 is transferred to the dispensing section 8 through a discharging path 9-- which consists of rollers.
2, placed in a horizontal state, and transferred to the unloading path 9.
-2, it is carried out in _{the two} directions of arrow A. and,
The plate material holder 4, which is now empty after the plate material 7 has been delivered, is once again conveyed to the receiving section 6 side (in the direction of arrow B) by the conveyor chain 3, and the plate material transfer as described above is repeated.

[Problem that the invention seeks to solve]

In the structure described above, all of the large number of plate holders 4 are fixed to the conveyor chain 3 and move together with the conveyor chain 3, so that the receiving section 6 and the dispensing section 8 can only operate synchronously at all times. For this reason, there is a problem in that the plate material 7 cannot be rapidly forwarded from the receiving side to the dispensing side in order to continuously feed the plate material 7 smoothly in response to fluctuations in the processing time of the pre- and post-processing devices. That is, the above conventional example can only be used as a device exclusively for receiving or dispensing the plate material 7.

[Means for solving problems]

The present invention provides a fast-forwarding mechanism for a plate material stocker that solves the above-mentioned problems.As a means thereof, according to the present invention, there is provided an input part having a plate receiving mechanism, and a plate material transferred from the input part. In a plate material stocker comprising a stocking part for stocking and an output part having a dispensing mechanism for discharging the plate material from the stocking part, on a rail arranged in a loop between the receiving mechanism and the dispensing mechanism, A large number of plate material holders that can freely run around are provided, and an endless belt that runs close to the holders and transports the holders is provided, and can automatically engage the holders and the belt at opposing positions. A fast-feeding mechanism for a plate material stocker is provided, which includes an engaging member, and fast-feeds the holder while rotating the belt and engaging the holder with the engaging member.

As an example, it is preferable that the engaging member is a magnet attached to one of the opposing positions of the holder and the belt, and a magnetic material or a magnet attached to the other.

[Effect]

The fast-feeding mechanism of the plate material stocker mentioned above is such that the engaging member attached to the endless belt for conveyance automatically engages with the engaging member attached to the plate material holder to rapidly feed the plate material holder. Through this holder, the plate material can be quickly transported and stored from the receiving side to the dispensing side. This makes it possible to smoothly transfer the plate material in response to fluctuations in processing time of the pre- and post-process equipment.

A plurality of magnets 27 are attached to the outer surface of the belt 26 at predetermined intervals (for example, about 400 mm pitch) so as to face the magnetic material 14e of the hanger 14. Therefore, the belt 26 runs while the magnet 27 approaches the magnetic material 14e of the hanger 14 in a free state and attracts the magnetic material 14e, so that the hanger 14 can be transported in the clockwise direction (in the direction of arrows J and K). It is located in The hanger 14 thus transferred is stopped and stored upstream of the receiving mechanism 11-2 and the dispensing mechanism 13-2 by the stopper mechanisms 46 and 47, respectively. The speed of this belt 26 is set higher than the processing line speed, for example, it is often set to about twice the processing line speed.
You can fast forward and stock up. Therefore, as an example, the processing line speed is 1.6m/S.
If the speed of the belt 26 is approximately twice as high as 3
It is set to about m/S. In reality, both left and right ends of the magnet 27 are fixed onto the belt 26 by fittings (not shown), and an abutment roller (not shown) is attached to the fittings. When the magnet 27 attracts the magnetic material 14e of the hanger 14, this contact roller contacts the lower surface of the horizontal member 14a and creates a minute gap g (see FIG. 2, for example) between the magnet 27 and the magnetic material 14e. , about 0.5 mm) to prevent direct contact between the two, thereby preventing noise generation and smoothing the rotation of the belt 26.

In addition, the receiving mechanism 11-2 and the dispensing mechanism 13-2
is the same mechanism as described above, and is constructed as described below. Left and right side plates 22-1, 22-2
The support shafts 23 and 33 supported by the support shafts 23 and 33 are connected to the 90° indexes 24-1 and 24-2, respectively, and are driven to rotate. A pair of left and right discs 34, 34 are inserted and fixed to the support shafts 23, 33, respectively. each disk 3

They are arranged at 90° intervals and are mounted so as to be slidable in the radial direction. Each engaging claw 35 has an engaging groove 35a at its outer end for fitting and holding the hanger 14.
is formed, and a roller 35b is provided at the inner end. Then, each engaging pawl 35 is applied with a pressing force toward the center of the disk 35 by a tension coil spring 37, thereby causing the roller 35b to move toward the rotating cam 3.
It is elastically pressed against the outer periphery of 8A, is driven to protrude and retract in the radial direction by the cam 38A, and is driven in the circumferential direction by the disk 35. The rotating cams 38A are fixed to both ends of a hollow cylindrical outer shaft 38B rotatably disposed around the outer periphery of the support shafts 23, 33, and are driven by the outer shaft 38B. The outer shaft 38B is rotated in the forward and reverse directions with respect to the support shafts 23 and 33 individually within a predetermined rotation angle range by a drive device (not shown) such as a cylinder via a drive plate 38C and a pin 38D fixed thereto. As a result, the cam 38
A is driven, and in conjunction with this, the engaging claw 35 is driven to protrude and retract at a predetermined position. In addition, the stopper mechanism 46,
47 is a pair of parallel cylinders 46-
1 and 46-2, and 47-1 and 47-2, and their piston rods 46a-1 and 46a-
2, and 47a-1 and 47a-2 perform a protruding or retracting operation as necessary, so that the hanger 1
4 is stopped and stocked, and one by one is sent out independently to the receiving mechanism 11-2 and the dispensing mechanism 13-2.

Next, the operation of this embodiment configured as described above will be explained with reference to FIG. In the figure, the belt 26 is constantly rotated clockwise (in the direction of arrows J and K). Therefore, the empty hanger 14 (lower hanger 14 in the figure) is transported in the direction of arrow K while its magnetic material 14e is attracted by the magnet 27 of the belt 26, and is stopped by the stopper mechanism 46. In this state, the receiving mechanism 11-2 rotates the cam 38A, causes the engagement claw 35 to protrude, and holds the empty hanger 14 in the engagement groove 35a.
Next, the engaging claw 35 moves the disk 34 clockwise (in the direction of arrow G) while holding the hanger 14.
The hanger 14 is rotated by 90 degrees and stopped in a state where the hanger 14 is held horizontally and opposed to the carry-in path 11-2. In this state, the plate material 15 is carried in from the direction of arrow D on the receiving side through the carry-in path 11-1, fits into the receiving groove 14d of the hanger 14, and is held by the hanger 14. Then the disk 34
is rotated 90 degrees clockwise (in the direction of arrow G), and the hanger 14 and the plate 15 are rotated and transferred upright toward the stock section 12. Continued engagement claw 3
When the hanger 14 is retracted toward the center by rotation of the cam 38A, the hanger 14 is released from the engaging claw 35 and becomes free, and the magnetic material 14e is attracted to the magnet 27 of the belt 26 and transferred in the direction of arrow J. . This hanger 14 is then stopped by a stopper mechanism 47 on the dispensing side. The plate material 15 transferred to the receiving side in this way remains held on the hanger 14 and is moved to the rail 25-1.

Rotate the disk 34 90 degrees clockwise to remove the plate 15.
horizontally onto the unloading path 13-1, and
3-1, it is carried out in the direction of arrow E. after that,
When the engaging claw 35 is retracted toward the center by the action of the cam 38A, the empty hanger 14 is transferred in the direction of arrow K by the belt 26. By repeating the above operations, the plate material 15 can be received, stocked, and dispensed. The fast-feeding mechanism including the belt 26 can rapidly feed the plate material 15 individually without synchronizing with the receiving mechanism 11-1 and the dispensing mechanism 13-2.

〔Effect of the invention〕

As explained above, according to the present invention, a large number of plate material holders (hangers) that can run freely around the loop-shaped rail and an endless belt that rotates close to the holders are provided. By providing engagement members that can be automatically engaged at opposing positions of the two, an effect can be obtained in that the plate holding member can be rapidly fed, that is, the plate can be rapidly fed. This makes it possible to smoothly transfer the plate material in response to fluctuations in processing time of the pre- and post-process equipment. still,
