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. This relates to a plate stocker for transferring.

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 equipment and processed. In this case, the processing time of each processing apparatus often varies due to variations in the size (for example, length), thickness, etc. of the plate material, or differences in processing capacity of the apparatuses themselves. Therefore, it is desired that this type of sheet material stocker has the function of smoothly and efficiently receiving and discharging sheet materials in response to fluctuations in processing time of pre- and post-process equipment. Ru.

[Technology of technology]

FIG. 7 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 fixedly arranged on the conveyor chain 3 at predetermined intervals. The plate material holder 4 has a receiving groove 4a for receiving and holding a plate material (for example, a printed board) 7.
is formed. The conveyor chain 3 is rotated between the pulleys 1 and 2 together with the holder 4 in the directions of arrows A and B by the rotation of the pulley 2 by the motor 5 . 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 the leading end side is fitted into the receiving groove 4a of the plate material holder 4 waiting in the receiving section 6. is held by the plate material holder 4, and is moved to the dispensing part 8 side (arrow A) by the conveyor chain 3.

The empty plate material holder 4 that has been discharged is again conveyed by the conveyor chain 3 to the receiving section 6 side (in the direction of arrow B), 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 fixedly installed on 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 it is not possible to simultaneously receive and deliver the plate material 7 in response to fluctuations in the processing time of the pre- and post-process processing apparatuses. That is, the conventional example described above has a problem in that it can only be used as a device exclusively for receiving or dispensing the plate material 7.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a loop-shaped rail disposed between a board material loading path and a board material unloading path, and a large number of board material holders that can freely run around the rail. and an endless belt carrying a magnet that runs close to the holder and uses magnetic attraction to transfer the holder, and the upper horizontal portion of the loop-shaped rail constitutes a stock portion. , the front swinging part constitutes a receiving mechanism for receiving the board carried in from the carry-in path by the holder, and the rear swing part constitutes a dispensing mechanism for discharging the board held by the holder to the carry-out path. A mechanism is configured to stop and store the holders on the upstream side of the rails of the receiving mechanism and the dispensing mechanism, and indexing the holders one by one and feeding them independently to the receiving mechanism and the dispensing mechanism, respectively. A plate material stocker is provided, which is provided with a stopper mechanism and further includes means for forcibly turning the holder at each of the turning portions independently of the operation of the endless belt.

[Effect]

The above-mentioned sheet material stocker has an input section and an output section that can each independently transfer the sheet material, and the stocking section has the function of temporarily holding and stocking the sheet material, so it is possible to transfer the sheet material to the pre- and post-process equipment. It is possible to smoothly perform both the receiving and discharging operations of the plate material in response to the fluctuations in the amount of the plate material.

The receiving mechanism 11-2 is supported by a support shaft 23 supported by left and right side plates 22-1 and 22-2 erected on the base 21. The support shaft 23
It is connected to a 90° index mechanism 24-1 and driven to rotate. A pair of left and right discs 34 are mounted on the support shaft 23,

The figure is an explanatory view of the structure and operation of the rotary cam 38A section and the engaging claw 35 as seen from the direction of arrow F in FIG. 3. Fourth
As shown in the figure, the cylinder 43 is arranged substantially horizontally in correspondence with the drive plate 38C. The base end 43a of the cylinder 43 is rotatably supported by a fixed pin 44, and the tip end of the piston rod 43b is rotatably connected to a pin 38D fixed to the drive plate 38C. Four engaging claws 35 are arranged on the disk 34 at 90° intervals on the vertical center line P and on the horizontal center line Q perpendicular to these, and their inner ends are attached to the four engaging claws 35. cam 38A via the roller 35b
is elastically pressed against the outer circumferential surface (cam surface) of the still,
In this case, the four engaging pawls 35 are designated by numerals 35-1, 35-2, 35-3, and 35-4, respectively, for convenience of explanation. Cam 38A is large diameter cam surface 3
8A-1 and a small diameter cam surface 38A-2. The cam 38A rotates the pin 38D at rotation angles α and β back and forth with respect to the center line P by the reciprocating movement (in the direction of arrow L) of the piston rod 43a of the cylinder 43.
By being driven to the position, it is rotated to the positions corresponding to α and β in conjunction with this pin 38D.
This rotational movement of the cam 38A causes the engagement claw 35-1 to
~35-4 are moved in and out of the disk 34 in the radial direction. Therefore, when the roller 35b of the engaging claw 35 is rolled onto the large diameter cam surface 38A-1 of the cam 38A, the engaging claw 35 is moved to a position where it protrudes outward and engages the hanger 14, and the roller 35b is moved onto the small diameter cam surface 38A-1 of the cam 38A. Cam surface 38A-
2, it sinks inward and the hanger 14
is moved to a position where it is released. Note that the relationship α≒β is set, and the sum of these two is, for example,
It is set at about 30°. Now, the cam 38A is set corresponding to the position where the pin 38D is first moved to the position α (as shown by the two-dot chain line in FIG. 4). At this time, the engaging claw 35-1 on the center line P is connected to the cam 38.
The engaging pawl is pressed onto the small diameter cam surface 38A-2 of A and is maintained in the inwardly recessed position, that is, the release position with respect to the lower hanger 14 on the center line P, and the engagement claw is on the one-way center line P. 35-3 is maintained in a position where it is pressed against the large-diameter cam surface 38A-1 of the cam 38A and protrudes outward, that is, in a position where it engages and holds the upper hanger 14 on the center line P. Next cam 38A
is the position corresponding to the position β as the pin 38D is moved from the position α to the position β, that is,
It is rotated to the position shown by the solid line in FIG. Along with this rotational movement of the cam 38A, the roller 35b of the engaging claw 35-1 is moved onto the large diameter cam surface 38A-1 and protrudes outward, so that the engaging claw 35-1 is lowered and stopped on the center line P. It engages with the hanger 14 on the side via the engagement groove 35a, and the engagement claw 35-3 engages with the roller 35b.
is moved onto the small diameter cam surface 38A-2 and sinks inward to release the upper hanger 14 on the centerline P.
As a result, the released hanger 14 is transferred along the rail 25-1 (25-2) in the direction of arrow J (see FIG. 2) and is transferred to the stock portion 12 (first,
Figure 2). In addition, at the same time, the engaging claw 35-2 on the horizontal center line Q is connected to the large diameter cam surface 38A-
1 to hold the hanger 14 horizontally,
This hanger 14 receives and holds the plate material 15 (Fig. 2) carried in horizontally from the carry-in path 11-1 (Fig. 2) via the receiving groove 14d. On the other hand, the engaging claw 35-4 is located on the small diameter cam surface 38A-2 in an empty state. Now, next, the engaging claw 35-1 is moved by the arrow G by the disc 34 while holding the hanger 14.
The roller 3 is rotated 90 degrees in the direction and is placed on the horizontal center line Q, that is, at the position where the engaging claw 35-2 is
5b is transferred by rolling on the large diameter cam surface 38A-1. At the same time, the engaging claw 35-2 is
3, 35-3 to 35-4, and 35-4 to 35-1. And during this time, cam 3
8A is returned to its original position corresponding to the position α of pin 38D. Now, the engagement claw 35-1 is the engagement claw 35-1.
-2 is moved to the position where it is located, and the hanger 14
receives and holds the plate material 15 in the same manner as in the case of the engaging claw 35-2 described above, and is again rotated by 90 degrees in the direction of the arrow G by the disc 34 to be placed on the vertical center line P.
That is, the engaging claw 35-3 is moved to the position where it is located, and then the hanger 14 is released. after that,
The engaging claw 35-1 is connected to the engaging claw 35-4 by the disc 34.
is returned to the initial position via the position where it was located, and the same operation as above is repeated.
In addition, the other engaging claws 35-2, 35-3 and 35-4
The engagement claw 35-1 also performs the same operation as the engagement claw 35-1, with the phases shifted by 90 degrees. In this way, the receiving mechanism 11-2 is configured to receive the plate material 15 carried in from the carry-in path 11-1 (FIG. 2), rotate it at 90° intervals, and feed it into the stock section 12 in an upright manner. There is.

The stock section 12 is constructed as follows. Left and right side plates 22 erected on the base 21 (Fig. 3)
-1, 22-2, a pair of loop-shaped left and right rails 25-1, 25-2 are arranged to connect the receiving mechanism 11-2 and the dispensing mechanism 13-2. rail 2
A large number of hangers 14 are arranged on the hangers 5-1 and 25-2, which can freely move around. hanger 14
is the horizontal member 14a and the vertical members 14b and 14b at both ends.
It is formed into an H shape, and four running rollers 14c are provided at both ends corresponding to the horizontal member 14a, and these four rollers 14c form pairs of two upper and lower rollers to form rails 25-1, 25-2 is placed between them. In addition, hanger 14
A plate receiving groove 14d is formed inside each of the vertical members 14b at both ends, and a magnetic material (or magnet) 14e is attached to the center of the lower surface of the horizontal member 14a. An endless belt (flat belt or timing belt) 26 for transferring the hanger 14 is placed opposite the lower surface of the magnetic material 14e at the receiving mechanism 11-2.
There are four pulleys 45 between the and dispensing mechanism 13-2.
spanned by. Four pulleys 45 are provided integrally at the front end (receiving mechanism 11-2 section) and rear end (dispensing mechanism 13-2 section) of the stock section 12, one of which is connected to the belt 29 (the second section). 1 and 3) by a drive motor 28 (FIG. 1), the belt 26 is rotationally driven in a clockwise direction (in the direction of arrows J and K). A plurality of magnets 27 are mounted on 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, in FIG. 2, when the belt 26 is rotated in the direction of the arrow J (and the direction of the arrow K), the magnetic material 14e of the hanger 14 in the free state is attracted to the magnet 27 of the belt 26, and the hanger 14 rotates in the direction of the arrow J and arrow K. It is automatically transferred in the K direction, and stopped and stored upstream of the receiving mechanism 11-2 and the dispensing mechanism 13-2 by stopper mechanisms 46 and 47, which will be described later. The speed of this belt 26 is often set to about twice the processing line speed, so that the hanger 14 can be moved quickly and stored. For example, if the processing line speed is
In the case of about 1.6 m/s, the speed of the belt 26 is set to about twice that, about 3 m/s. The magnet 27 is actually fixed at both left and right ends onto the belt 26 by mounting 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. 3, 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. Now, adjacent to both left and right ends of the belt 26, the receiving mechanism 11-2 and the dispensing mechanism 13-
2 to form a pair of left and right guide rails 3 in a loop shape.
0-1 and 30-2 are arranged. Guide rail 3
Guide grooves 30-1a and 30-2a that go around in a loop shape are formed on the outer circumferential surfaces of 0-1 and 30-2, respectively. Then, the horizontal member 14 of each hanger 14
On the lower surface of a, these left and right guide grooves 30-1a, 3
Two guide rollers 14f that fit into either one of the rollers 0-2a and are arranged in pairs in the front and rear are provided, respectively. In other words, the reference numeral 14-1 in FIG.
With respect to the front and rear adjacent hangers indicated by and 14-2, the front hanger 14-1 is provided with a guide roller 14f that fits into the right guide groove 30-2a, while the rear hanger 14-2 The guide roller 14f fits into the left guide groove 30-1a.
will be placed. In this way, the guide rollers 14f are arranged alternately on the left and right for each hanger 14 adjacent to each other in the front and back. This is devised so that the distance between the front and rear of each stocked hanger 14 can be reduced. The guide rollers 14f are arranged as a pair of front and rear, so that the hanger 14
The guide grooves 30-1a and 30-2a serve to prevent the hanger 14 from skewing when it is transported around the rails 25-1 and 25-2. Now, stopper mechanisms 46 and 47 are respectively disposed on the upstream side of the transfer of the hanger 14 between the receiving mechanism 11-2 and the dispensing mechanism 13-2. The stopper mechanisms 46 and 47 include a pair of cylinders 46-1 and 46-2 and 47-1 and 47- which are arranged in parallel.
The piston rods 46a-1 and 46a-2 and 47a-1 and 47a-2 are connected to the side plates 22-1, 22-2 and the guide rail 25-1,
The side plate 22- can be inserted and retracted by penetrating through 25-2.
1 and 22-2 are arranged symmetrically.
The stopper mechanisms 46 and 47 are the same mechanism and are configured to individually perform the same operation. Therefore, as a representative example, the operation of the stopper mechanism 46 will be explained with reference to FIG. In addition, in FIG. 5, the reference numeral 25-2 indicates a loop-shaped rail as described above, and for the sake of easy explanation, a specific hanger is indicated by the reference numeral 14-2.
1, 14-2, and 14-3, respectively. Now, as shown in Figure 5 A, point the arrow K on the rail 25-2.
The piston rod 46a-1 protrudes and stops the hanger 14-1 that has been transferred in the direction (FIG. 2, the direction from the dispensing mechanism 13-2 to the receiving mechanism 11-2), and the hanger 14-1 is thereby stopped.
2, 14-3 to 14 are sequentially stopped and stocked. At this time, the piston rod 46a-2 is recessed as shown in the figure. Next, as shown in the figure below, the piston rod 46
a-2 protrudes and holds the hanger 14-1 between it and the piston rod 46a-1.
4-Stop and stock hangers below 2. The position of this clamped hanger 14-1 corresponds to the position of the lower hanger 14 on the vertical center line P in FIG. 4 described above. In this state, the hanger 14-1 is in the fourth position.
The engaging claw 35-1 illustrated in the drawing projects outward from the disc 34 and is engaged and held by the engaging claw 35-1.
Next, as shown in Figure C, the piston rod 46a-1 retracts to release (freely) the hanger 14-1 from the stopper mechanism 46. This released hanger 14-1 is transferred in the direction of arrow G by the engaging claw 35-1. Next, as shown in Figure 2, the piston rod 46a-1 protrudes again. Next, as shown in Fig. E, the piston rod 46a-2 is retracted and the hanger 14-2 is stopped by the piston rod 46a-1, resulting in the same state as shown in Fig. A, and then the piston rod 46a-1 , 46a-2 repeating the same operations as described above, the hangers 14-2 and below are indexed and transferred in the same manner as in the case of the hanger 14-1. Incidentally, the protruding operation of the piston rod 46a-1 in Fig. 2 and the retracting movement of the piston rod 46a-2 in Fig. 5 are not independent operations as described above, but may be made to operate synchronously. The stock section 12 is constructed as described above,
It has a function of storing a large number of hangers 14, and also indexes and receives them one by one.
-2 and the dispensing mechanism 13-2 each have an individual dispensing function.

Now, the dispensing mechanism 13-2 of the output section 13 is supported by a support shaft 33 that is supported by the left and right side plates 22-1 and 22-2 and is connected to and rotationally driven by the 90° index mechanism 24-2. It will be done. This dispensing mechanism 13-2 is basically the same mechanism as the above-mentioned receiving mechanism 11-2 and is configured to perform the same operation, and is the same as the receiving mechanism 11-2 when it is reversed 180 degrees in the front-back direction. It was placed in Therefore, the dispensing mechanism 13-2 includes the same parts as the receiving mechanism 11-2, and cooperates with the stopper mechanism 47 to deliver the plate material 1 to the stock portion 12.
The plate material 15 is delivered by rotating and transporting the hangers 14, which are held upright and holding the hangers 5 one by one, horizontally with respect to the delivery path 13-1. The dispensing mechanism 13-2 is configured to operate independently without synchronizing with the operation of the receiving mechanism 11-2.

The delivery path 13-1 is provided adjacent to the delivery mechanism 13-2. The unloading path 13-1 is basically:
The structure is almost the same as the carry-in path 11-1. That is, an endless belt that acts as a conveyor (e.g.
Rubber timing belt) 36-1, 36-2
Two of them are arranged on each of the left and right sides of the carry-out path area. Pulleys (for example, timing pulleys) 48-1, 48-2 on which these belts are hung are arranged in pairs on the front and rear sides of the left and right sides, respectively. Rotating shafts 49-1 and 49-2, which are rotatably supported on both left and right sides and fixedly support pulleys 48-1 and 48-2, respectively, are disposed at the front and rear. The motor 39 (Fig. 1) for rotationally driving the rotating shaft 49-2 via a gear mechanism is connected to the rotating shaft 49-2.
It is arranged adjacent to 2. Rotating shafts 49-1 and 49
A plate passage detector 4 equipped with a plate passage detection sensor (for example, an optical reflective sensor) 42a between the
2 (FIG. 1) is provided. The conveyance path 13-1 configured in this way is connected to the belt 4 by the motor 39.
8-1 and 48-2 are constantly rotated clockwise (the upper side of the belt is in the direction of arrow E), and the dispensing mechanism 13
-2, the plate material 15 (see Fig. 1) is carried out in the direction of arrow E, that is, toward the subsequent process. The plate material passage detection sensor 42a is positioned and fixed by sliding arbitrarily on the detector main body 42b in accordance with the length of the plate material 15. The reason for providing a plurality of sensors 42a is to accommodate a plurality of lengths of the plate material 15. When the plate material 15 passes over a predetermined sensor 42a, the sensor 42a sends a passing signal of the plate material 15 to a control device (not shown), and the control device sends a drive signal to the dispensing mechanism 13-2 based on this signal. do. The dispensing mechanism 13-2 performs the dispensing operation of the next plate material 15 based on this signal. In this way, the discharged plate materials 15 are controlled so as not to overlap each other. The plate length detector 41 (FIG. 1) serves to detect in advance the length of the plate 15 to be delivered and to send this signal to the control section. The carrying-out auxiliary belts 40 (FIG. 1) are provided as a pair on the left and right, and are used to ensure that the plate material 15 discharged from the dispensing mechanism 13-2 is transferred to the belt 36 for carrying out.
-1, 36-2, and is arranged as shown in Fig. 6. FIG. 6A is a side view showing the mounting structure of the auxiliary belt 40 seen from the direction of arrow M in FIG. 1, and FIG. In the figure, a pulley 50-1 is supported and fixed to a rotating shaft 49-1. A support member 51 is rotatably attached to the support shaft 49-1 adjacent to the pulley 50-1. A pulley 50-2 is rotatably attached to the tip of the support member 51 in correspondence with the pulley 50-1. An auxiliary belt 40 is hooked around these pulleys 50-1 and 50-2. A protrusion piece 51a is integrally provided at the base end portion of the support member 51. Projecting piece 51
One end side of the tension coil spring 52 is locked to a, and the other end side is a locking member 53A fixedly installed on the base.
is locked. As a result, a clockwise rotational force is applied to the support member 51. On the other hand, the protruding piece 51
a is stopped by the stopper 53B at an appropriate position, that is, at a position where the upper surface of the belt 40 on the pulley 50-2 is approximately the same as the upper surface of the carry-out belt 36-1. Since the auxiliary belt 40 is attached as described above, the belts 36-1 and 3 for carrying out
The belt 36- is rotated in the same direction as the belt 36-2.
1, 36-2, and securely transfers this plate material 15 to belts 36-1, 36-2.
It will be sent on 36-2. Note that this auxiliary belt 40 is similar to the belts 36-1, 36- for carrying out.
If the outer circumferential surface of No. 2 (the surface that contacts the plate material 15) has sufficient frictional force, it may be omitted.
In addition, in FIG.
A pair of plate turning stoppers are shown facing each other on the left and right sides of the stock part, and 55 is a fullness sensor provided on the side of the stock part. The swing stopper 54 is composed of a cylinder mechanism and has a rod 54a that can be retracted inward in the left and right direction. This will be supported once. That is,
The swing stopper 54 is caused by the bending of the plate 15 due to its own weight, so that the tip of the plate 15 is bent by the belts 36-1, 36.
- 2 plays the role of preventing contact with the previous plate material 15 being carried out. The fullness sensor 55 detects when the stock portion is full of the plate material 15, that is, the hanger 14.

〔Effect of the invention〕

As explained above, according to the present invention, the human power section 11 and the output section 13 can each independently perform the receiving operation and the discharging operation of the plate material 15, and the stock section 12 is arranged in a loop shape. A large number of hangers 14 that can freely run around are transferred arbitrarily, and the hangers 14 are moved by the stopper mechanisms 46 and 47.
It is possible to stop and stock the plate materials 15 and to index them one by one to the input section 11 and the output section 13 as necessary, so that the receiving and processing of the plate materials 15 can be done in response to fluctuations in the processing time of the front and rear process equipment. The practical effect of being able to perform both dispensing and dispensing smoothly is remarkable. Therefore, according to the present invention, the plate material 1 is
5 can be transferred rationally, and the operating rate of each process equipment can be improved.
