Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when manufacturing a memory hard disk or the like, punches a plate-shaped raw material with a press machine or the like to form a large number of disks, and conveys this to a stacking step by a conveyor. The present invention relates to a method and an apparatus for reversing a disk.

[0002]

2. Description of the Related Art Discs formed by punching with a press machine are stacked as they are stacked due to the warpage imparted at the time of punching. Is being done.

Various methods have been proposed for alternately stacking the disks conveyed on the conveyor in the reverse direction. For example, the conveyors where multiple discs are transported face up and the conveyors where multiple discs are transported face down intersect at the stacking position at the stacking position, and the discs are alternately ejected from these conveyors. It is conceivable that stacking will alternate between the front and back.

However, since a plurality of conveyors are installed in this method, a large work space is required, and when the discs are conveyed face up from the punching process, the punched discs are directly conveyed to the conveyor. Although it may be moved to the upper side, in order to convey the punched disc face down on the conveyor, the punched disc must be turned inside out and placed on the conveyor. For the purpose of putting it on the conveyor, for example, since complicated disk transfer means such as dropping from the reversing conveyor to the transfer conveyor installed below it and transferring it is required, the equipment becomes large-scale and the disk becomes large. Is not preferable because it tends to be damaged.

[0005]

One of the problems to be solved by the present invention is to use one conveyor for sequentially transferring the disks in the same direction among the plurality of disks sequentially transferred. An object of the present invention is to provide a disc reversal processing method capable of reversing an arbitrary disc.

Another object of the present invention is to provide a disc reversal processing method capable of reversing an arbitrary disc among a plurality of discs with almost no damage to the discs.

Another problem to be solved by the present invention is to use a single conveyor in which the disks are sequentially transferred in the same direction and invert any disk among a plurality of disks sequentially transferred on this conveyor. DISCLOSURE OF THE INVENTION It is to provide a disk inversion processing device capable of performing the above.

Yet another object of the present invention is to provide a disc reversal processing device capable of reversing any one of a plurality of discs without damaging the discs.

[0009]

The first means for solving the problems of the present invention is to pick up a disk carried on a conveyor with the receiving port of the disk holder facing the upstream side of the conveyor and pick up the disk in this manner. To provide a disk reversal processing method characterized in that the disk holder is moved so that the disk is turned upside down, and a disk in the disk holder is returned onto the conveyor with the receiving port of the disk holder facing the downstream side of the conveyor. is there.

A second object solving means of the present invention is a disk reversal processing method according to the first object solving means, wherein an arbitrary disk selected from a plurality of disks conveyed on a conveyor is a disk holder. An object of the present invention is to provide an inversion processing method for a disc that is turned inside out.

A third object solving means of the present invention is a disk reversal processing method according to the first object solving means, wherein it is detected that the disk in the disk holder is sandwiched between the disk holder and the conveyor. And a method of reversing a disk, wherein the disk holder is temporarily reversed slightly in the circumferential direction to release the disk from being sandwiched between the disk holder and the conveyor. It is in.

A fourth means for solving the problems of the present invention is a conveyor for transferring a disk, a disk inverting means having at least one disk holder installed in the middle of the conveyor and having a receiving port for receiving the disk, the conveyor and the disk inverting. Drive means for driving the means, the disk holder comprises a pair of holder pieces arranged on both sides of the conveyor belt in the width direction, and the drive means comprises a disk holder of the disk inverting means Pick up the disc to be carried over through the receptacle and move the disc picked up in this way to turn it over and drive the disc holder to put the thus flipped disc back onto the conveyor It is to provide a disk inversion processing device characterized by the above.

A fifth problem solving means of the present invention is a disk reversal processing device according to the fourth problem solving means, wherein the driving means sandwiches the disk in the disk holder between the disk holder and the conveyor. It includes a disc pinch detector that detects that the disc is pinched and a reverse rotation command generator that temporarily reverses the circumferential movement of the disc holder when the disc pinch detector detects pinching of the disc. A feature of the present invention is to provide a characteristic disk reversal processing device.

In this way, the disc conveyed on the conveyor is picked up by the disc holder and turned upside down,
Then, if you return it from the disc holder onto the conveyor, you can flip any disc on the conveyor.
It is possible to mix front-side and back-side discs on one conveyor, so that one selected conveyor can be flipped using a single conveyor in which multiple discs are sequentially fed in the same direction. Typically, every other disc conveyed on the conveyor can be inverted and conveyed alternately face up and face down, but as will be described later in detail, face up, face up, It can be face down, face up, face up, ---, or can be reversed for any number such as face down, face down, face up, face down, face down, ---.

Further, since the disc is picked up by the disc holder and turned inside out, unlike the case where a plurality of conveyors are provided with steps and are dropped inside out.
There is less risk of damaging the disc, and further, when the disc holder returns the disc to the conveyor, the disc holder is temporarily reversed, and the drive means is appropriately controlled so that the disc is moved between the disc holder and the conveyor. The disc quality can be maintained without being damaged by being sandwiched by.

As described above, when the disc is prevented from being sandwiched between the disc holder and the conveyor by temporarily reversing the disc holder or the like, the flow of the disc does not stop on the conveyor and the post-processing of the disc is prevented. There is no adverse effect.

According to the present invention, for example, a plurality of disks, which are conveyed in the same direction on one conveyor and are spaced apart from each other, are turned over by using a disk reversing means, and the plurality of disks on the conveyor are reversed.

It consists of a pair of holder pieces. This disc holder first picks up the disc conveyed on the conveyor with the receiving port facing the upstream side of the conveyor, moves the disc holder picking up the disc in this way so that the disc is turned upside down, and then the receiving port. To the downstream side of the conveyor, and put the disk in the disk holder back onto the conveyor.

When the disc holder moves in the circumferential direction (angular displacement) about an axis extending in the direction transverse to the conveyor near the conveyor surface, the disc holder picks up one disk above the conveyor conveyor surface. From this position to the position of turning this disc over and back on to the conveyor, and then subsequently in the same direction below the conveyor's transport surface to return to the position where it picks up another disc that is trailing on the conveyor, and so on. The disc can be turned over in the same manner. In this case, the plurality of disc holders can be arranged at an angular interval around the rotation axis, and the plurality of disc holders can invert any selected disc among the plurality of discs on the conveyor. .

The disc reversing means may be driven so that one disc holder swings about an axis extending in the direction transverse to the conveyor near the conveying surface of the conveyor. In this case, the disc holder is located between the position where the receiving port faces the upstream side of the conveyor to pick up the disc above the conveying surface of the conveyor and the position where the receiving port faces the downstream side of the conveyor and returns the disc onto the conveyor. Move back and forth.

When the disc holder moves in the circumferential direction around an axis extending in the direction transverse to the conveyor near the conveying surface of the conveyor, when the disc holder returns the disc onto the conveyor with its receiving point facing upstream of the conveyor. In addition, the disc may be sandwiched between the transport surface of the conveyor and the disc holder. As described above, the disc that is about to be returned onto the conveyor by detecting that the disc is sandwiched between the conveying surface of the conveyor and the disc holder and temporarily reversing the disc reversing means slightly is the disc disc. The pinched state between the holder and the conveyor is released.

The conveyor driving motor 32 is driven at a predetermined speed based on the supply speed of the disk 12.
It should be noted that the feedback signal Fs32 from the speed detector 44 of the motor 32 is fed back to the motor drive unit 38 to monitor whether or not the rotation speed of the motor 32 has reached a predetermined rotation speed. Does not correspond to the supply speed, the motor 32 is controlled to increase the rotation speed until it reaches a predetermined rotation speed.

As shown in FIG. 1, the driving means 20 includes three optical sensors, first to third, arranged in a work area from a position where the disk 12 is picked up from the conveyor 14 to a position where the disk 12 is returned to the conveyor 14. 48A, 48B,
48C and a fourth optical sensor 48D arranged at a position slightly upstream of the transport surface 14A of the conveyor 14 from the disk return position of this work area, and these optical sensors 48A to 48D The signal is input to the program controller 42 and the motor drive unit 38
And the servo motor drive unit 40 are controlled,
The details will be described later together with the description of the operation of the method of the present invention.

This control system has three relays R1 to R3 controlled by the program controller 42, and the first relay R1 is the motor drive unit 38.

This is a reverse rotation relay that opens and closes the reverse rotation normally open relay contact r3 that constitutes the command generator. Start / stop relay R1
And R2 are excited or degaussed by a manual switch (not shown), and the reverse relay R3 is, as will be described later,
It is excited when the disk 12 is sandwiched.

The drive means 20 used in the present invention is shown in FIG.
, A disc pinch detector 50 for detecting that the disc 12 in the disc holder 16 is pinched between the disc holder 16 and the transport surface 14A of the conveyor 14.
And a reverse rotation command generator 52 which temporarily slightly reverses the rotation of the disk inverting means 18 when the disk pinching detector 44 detects the pinching of the disk 12. The disk pinch detector 50 is, as will be described later, a galvanometer 5 for detecting the load current I of the servo motor 34.
6 is operated.

In the illustrated example, the disk pinch detector 50
As shown in FIG. 4, when the torque set by the torque setter 54 of the servo motor drive unit 40 is exceeded, it is determined that the disk 12 is sandwiched between the disk holder 16 and the conveyor 14, and the normally open contact 50a is opened. It consists of a relay that closes and generates a disc pinch signal Sh. The disc sandwiching signal Sh is input to the program controller 42, which temporarily activates the reverse rotation command generator 52 of the servo motor drive unit 40 to generate the reverse rotation signal Rs. In the illustrated embodiment, the reverse command generator 52 comprises a reverse relay contact r3 which is closed by the previously described reverse relay R3.

Next, the method of the present invention will be described with reference to FIGS. 1, 4 and 5.
More specifically, with reference to the following, a plurality of disks 12 punched by a press machine (not shown) at a predetermined punching speed are intermittently supplied onto the conveyor 14 one by one. The conveyor 14 moves at a predetermined speed by the conveyor driving motor 32 and conveys the disk 12 toward the disk inverting means 18, and the disk inverting means 18 causes the optical sensors 48A to 48D to detect the disk 12 as will be described later. The disk 12 is intermittently rotated by a predetermined angle in the clockwise direction in FIG. 5 or the like by sequential detection to perform the reversing operation of the disk 12. The details will be described with reference to FIG.

In the illustrated example, the disk inverting means 18 is
Since the four disc holders 16 are mounted on the pair of frames 22, 22 'at intervals of 45 degrees, one disc holder, for example, the disc holder 16A of FIG.
Is in a position to pick up the disk 12 from the conveyor 14, the preceding disk holder 16C, which is two preceding, is in a position to return the disk 12 to the conveyor 14. As shown in FIG. 5, when the disc holder 16 is in a position to pick up the disc 12 from the conveyor 14, the receiving port 16a thereof is provided.
Corresponds to the transport surface 14A facing the upstream side of the conveyor 14, and when the disc holder 16 is in a position to return the disc 12 to the conveyor 14, its receiving port 16a faces the downstream side of the conveyor 14 and transport surface 14A. It corresponds to.

In this state, as shown in FIG. 5, one disk 12A passes through the optical sensor 48A, and this disk 12 becomes one disk holder 1 of the disk inverting means 18.
This disc holder 16A through the receiving port 16a of 6A
Once inside, the first optical sensor 48A will
Detecting that 2 has entered the disc holder 16A,
This detection signal is input to the program controller 42. It should be noted that the discs denoted by reference numerals 12A and 12C in FIG.
Disc and disc holder 1 to be picked up by A
6C shows the disc returned to the transport surface of the conveyor 14 from 6C.

Therefore, the controller 42 controls the servomotor drive unit 40 to supply the drive signal Ds34 to the servomotor 34, the servomotor 34 rotates normally, and the disk reversing means 18 as a whole is centered on the axis of the rotary shaft 26. To move clockwise in FIG. In this way, the disc inverting means 18 moves (rotates) in the circumferential direction, and
As shown in, when the second optical sensor 48B detects the disk 12A in the disk holder 16A, this detection signal is input to the program controller 42, and the controller 42 controls the servo motor drive unit 40 to control the servo motor 34. Of the disk is stopped, and the disk reversing means 34 is stopped.

In this way, while the disc reversing means 18 is stopped, the disc 12S following the disc 12A picked up by the disc holder 16A is not picked up by the disc holder 16 of the disc reversing means 18 and is not rotated by the disc reversing means. When the disk 12S passes through the optical sensor 48D and the optical sensor 48D inputs a detection signal to the controller 42, the controller 42 is transferred to the servo motor drive unit 40.
And the servomotor 34 rotates in the normal direction.

By the normal rotation of the servo motor 34, the disk holder 16A moves clockwise from the position shown in FIG.
When the optical sensor 48C detects the disk 12A in the disk holder 16A, the controller 42 controls the servo motor drive unit 40 to stop the servo motor 34. Therefore, as shown in FIG. 7, the disc holder 16A stops at a position displaced by 90 degrees from the initial position in FIG. When the disc holder 16A is stopped at this position, the disc holder 1 immediately after that is stopped.
6D is in a position to pick up the disk 12D from the conveyor 14, and the previous disk holder 16B is in a position to return the corresponding disk 12B on the conveyor 14 in an inverted state. Therefore, by driving the conveyor 14, the disc holder 16D follows the disc 12S and then the conveyor 1
4 picks up the disk 12D that has been conveyed on the disk 4, and the disk holder 16B transfers the disk 12B to the conveyor 1
It is turned inside out and returned to 4.

In this way, the intermittent normal rotation of the servomotor 34 causes the respective disk holders 16 of the disk reversing means 18 to intermittently angularly displace around the axis of the rotary shaft 26, but the initial disk pick-up is performed. A position (see reference numeral 16A in FIG. 5), a position displaced by about 45 degrees from this pick-up position (45-degree displacement position), and a position further displaced by 45 degrees from this 45-degree angle displacement position, that is, the original pick-up position. From the 90 ° angular displacement position (90 ° displaced position) to the disk return position further 90 ° angular displacement from this 90 ° displaced position.

As shown in FIG. 5, the disc holder 1
While 6A is picking up the disk 12A, the disk 12C which has been turned over and returned from the second preceding disk holder 16C onto the conveyor 14 is conveyed by the conveyor 14, and this turned-over disk 12C is the fourth optical sensor. 48D, but in this case the fourth optical sensor 48D
Detected the passage of the disk 12C, but at this time,
Since the servo motor 34 is normally rotating in response to the detection signal from the first optical sensor 48A, the fourth optical sensor 48
The detection signal from D is the servo motor drive unit 40
Will not be adversely affected.

In this way, every other disk 12 sequentially supplied to the conveyor 14 is the disk reversing means 1.
8 is picked up and turned inside out, the conveyor 14
On the downstream side of, the discs 12 facing up and the discs 12S facing up are alternately conveyed, and thus the discs 12 facing up and down are alternately stacked in the stacking process.

On the other hand, for some reason, the conveying speed of the conveyor 14 and the moving speed (angular displacement speed) of the disk inverting means 18 do not match each other, and as shown in FIG. It is possible that the disc holder 16 may pinch the disc 12 with the conveying surface 14A of the conveyor 14 before it is returned to the corresponding disc holder 16 and ejected from the corresponding disc holder 16.

The torque setter 54 of the servo motor drive unit 40 determines the rotation torque of the servo motor 34 by Fk.
When the disk 12 is sandwiched between the transfer surface 14A of the conveyor 14 and the disk holder 16 as described above, and the rotation torque of the servo motor 34 exceeds this value Fkg · cm, it is detected. The sink 56 detects the load current I corresponding to this large torque, the relay of the disk pinch detector 50 is excited, the normally open relay contact 50a is closed, and the program controller 42 excites the reverse relay R3.

When the reverse rotation relay R3 is excited, the reverse rotation relay contact r3, which is the reverse rotation command generator 52, is closed, and the servo motor drive unit 40 causes the reverse rotation servo motor 3 to rotate.
4 is temporarily reversed slightly. As described above, the time for which the servo motor 34 is rotated in the reverse direction and is maintained in that state is set by the timer in the program controller 42, and the time is about 0.2 to 0.3 seconds. The reverse rotation angle of the disc holder 16 is preferably about 2 to 3 degrees (see FIG. 9).

As described above, when the servomotor 34 temporarily reverses slightly, the disc 12 in the disc holder 16 is sandwiched between the disc holder 16 and the conveying surface 14A of the conveyor 14, as shown in FIG. Is released from the state of being Since the conveyor 14 is still moving, when the disc 12 is released, the disc 12 is released.
Are unwound from the disk holder 16 by the conveyor 14 and returned onto the conveyor 14.

As described above, the motor drive unit 38 and the servo motor drive unit 40 have the signal S corresponding to the supply speed which is the punching speed of the disk 12.
Since the conveyor drive motor 32 and the disk reversing servomotor 34 are driven at a speed proportional to this supply speed after receiving s, the time during which the disk 12 is transported on the conveyor 14 and the time during which the disk 12 is turned upside down are provided. It is possible to perform the stacking of the disks satisfactorily without causing variations in the intervals at which the disks 12 are controlled and sent to the stacking process.

In the above embodiment, the disc 12 is moved to the disc holder 16 at the disc returning position of the disc holder 16.
The drive means 20 includes a disc pinch detector 50 and a reverse rotation command generator 52 of the servomotor 34 in order to release the pinch detector from the conveyor surface 14A of the conveyor 14 when it is pinched. For example, if the disc holder 16 is formed in a divergent shape toward the receiving opening 16a, or if the disc holder 16 has an opening that is sufficiently larger than the thickness of the disc 12, the disc holder 16 will not sandwich the disc. In this case, the driving means 20
The disc pinch detector 50 and the reverse rotation command generator 52 are not required.

In the above embodiment, the disk inverting means 1
8 includes four disc holders 16, but the number of disc holders is not limited to four, and may be one or a plurality other than four. Further, in the illustrated embodiment, the disc reversing means 18 has four disc holders 16 in the working area from the disc pick-up position to the disc returning position in order above the transport face 14A of the conveyor 14 and near the transport face 14A in one direction. Moves in a circumferential direction (rotational or angular displacement) around a rotation axis (a central axis of the rotation axis 26) extending across the same, and subsequently moves in the same direction in the non-working area below the conveyor surface 14A of the conveyor 14. Then
It is configured to return to the working area again to reach the disc pick-up position. However, for example, if the disc reversing means 18 comprises only one disc holder 16, the disc reversing means 18 allows the disc holder 16 to be transported in the work area above the transport surface 14A of the conveyor 14. It may be configured to oscillate (reciprocate) about a rotation axis extending across the vicinity of the surface 14A. In this case, if the disk holder 16 is provided with stopper means so that the disk holder 16 does not swing beyond the working area at both ends of the working area, the disk holder 1 will be in the disk returning position.
6 does not pinch the disk 12 with the transport surface 14A of the conveyor 14 or fail to pick up the disk 12 at the disk pick-up position.

Further, in the above embodiment, the conveyor 14
A plurality of discs conveyed above are alternately turned upside down so that the discs 12 are conveyed on the downstream side of the conveyor 14 alternately face up and face down. However, every two discs 12 are turned upside down. 12 face up, face up,
The discs 12 may be conveyed in the order of face down, or conversely, the disc 12 may be conveyed in the order of face up, face down, face down. In the latter case, the disc holder 16 of the disc reversing means 18
The positional relationship of is set according to such an inversion processing method.

Further, in the above-described embodiment, in order to convey the front-faced disk 12 on the conveyor 14 without inverting it, the disc-reversing means 18 is driven intermittently so that the front-faced disk 12 is removed while the disc-reversing means 18 is stopped. Although the disc is passed, the disc inverting means 18 may be continuously driven to pick up a disc facing up and pass it without inverting. This can be performed by appropriately setting the interval between the disc holders 16 adjacent to the disc inverting means 18 or the angular displacement speed of the disc inverting means 18.

[0052]

According to the present invention, as described above, the disc carried on the conveyor is picked up by the disc holder, turned inside out, and then returned from the disc holder onto the conveyor. Can be reversed to mix front-side and back-side discs on the conveyor, so multiple discs are fed in the same direction using one conveyor to properly arrange the discs face-up and face-down be able to.

Further, since the disc is picked up by the disc holder and turned upside down, unlike the case where a plurality of conveyors are provided with steps to turn over by dropping, the disc is less likely to be damaged, and further, the disc holder is not turned over. When the disk holder returns the disk to the conveyor due to the temporary reversing action of the disk etc., the disk quality can be maintained without being damaged by being pinched between the disk holder and the conveyor. There is a real advantage that the disk can be processed efficiently without obstructing the flow of the disk.
