Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a distractor feeder for feeding blanks to a press machine.

[Prior Art] Distack feeders are widely used to improve productivity and automate press machines.

Such a distack feeder feeds one blank from a plurality of blanks.
The blank is taken out and fed to the press machine I1Ill.

A conventional distack feeder includes a quantitative holding device that holds multiple blanks, a blank separating device that separates one blank from the multiple blanks held in this quantitative holding device, and a blank separating device that separates one blank from the multiple blanks held in this quantitative holding device. a suction device that suctions and takes out the material using a vacuum cup or the like;
It consists of a lift cylinder device that pushes up multiple blanks from below to a quantitative holding device. Further, the separating device generally has a structure in which a plurality of magnets are arranged facing each other with a distack center interposed therebetween.

Therefore, the blanks pushed up by the lift cylinder device are held by the quantitative holding device and separated one by one by the separating device.

Thereafter, the suction device transfers the separated uppermost single blank to an appropriate position for delivery to the press machine.

[Problems to be solved by the invention] However, the above-mentioned conventional disorder feeder has the following problems:
It had many problems as follows.

That is, even if the quantitative holding device/separation device is provided in advance at a predetermined position, it is quite difficult to position and stop a pallet containing a plurality of blanks at a predetermined position.

This is because, in terms of performance, it is necessary to set a small gap between each magnet of the separation device and the blank.

If you do not do this and push the blank up with a lift cylinder device while this condition is left unattended, the quantitative holding device and separation device may be damaged due to a collision.

In addition, in order to prevent such equipment damage, it is necessary to adjust the position of the quantitative holding device and separation device each time depending on the position of the blank pushed up by the lift cylinder device and the form of the blank. This requires excessive labor and requires an excessive amount of equipment and storage space. As a result, the productivity of press working decreases and costs increase.

In order to facilitate the above-mentioned replacement work, for example,
As disclosed in Publication No. 6531, a quantitative holding device and a separating device are assembled into a movable frame and replaced at another location. Since it is necessary to prepare a quantitative holding device, etc., the cost of equipment is large and it cannot be called a drastic countermeasure.In particular, it does not satisfy the current demands for pressing blanks of a wide variety of shapes.

In addition, when a plurality of magnets of a separation device are set with a small gap between blanks held in a quantitative holding device, at most the plurality of blanks are held between the lift cylinder device and the suction device from above and below. therefore,
There is also a problem in that all or part of the plurality of blanks are displaced in the horizontal direction due to the strong magnetic force of each magnet.

Further, the quantitative holding device and the separating device are set depending on the form of the target blank, that is, they are generally fixed to a frame or the like as disclosed in the above-mentioned publication. Therefore, after a plurality of blanks are once supported by the holding device, if the mold is replaced or the number of produced pieces is changed, it is extremely difficult to recover the blanks remaining in the quantitative holding device.

In particular, the form and number of quantitative holding devices installed are limited due to the relationship with the separation device, layout, and economical reasons. Therefore, it is not possible to stably hold blanks with complicated shapes or high weight blanks, and there is a drawback that the current demands for blanks of a wide variety of shapes and weights cannot be met.

The purpose of the present invention is to solve the above-mentioned problems, and to reduce the burden on the quantitative holding device, and to provide excellent applicability that can stably hold a wide variety of blanks and supply blanks smoothly and quickly. The objective is to provide a de-stack feeder with

[Means for Solving the Problems] The present invention provides a centering device, etc. that regulates the position of the blank before supplying it to the quantitative holding device, and also includes a pawl member on the centering device, etc. to reduce the load on the quantitative holding device. At least the claw member provided on the centering device is formed so that the direction thereof can be changed.

That is, there is a separation device having a plurality of magnets arranged oppositely with a distack center in between, a quantitative holding device that holds a plurality of blanks stacked between the magnets, and a separation device that adsorbs the separated blanks and transfers them to an intermediate conveyance means. In a distack feeder equipped with a suction device for delivery, a front stopper and a centering device that presses a plurality of blanks against the front stopper to regulate the position of the blanks relative to the quantitative holding device, etc. are arranged opposite to each other with the distack center interposed therebetween. The front stopper and the centering device are each provided with a claw member that supports the blank held between the magnets and reduces the load on the quantitative holding device, and at least the claw member provided on the centering device can be changed in direction within a horizontal plane. In order to achieve the above object, the centering device is attached to the centering device.

[Function] In the present invention having the above configuration, after the position is regulated by the cooperation of the front stopper and the centering device, a plurality of blanks are pushed up to the quantitative holding device, thereby preventing equipment damage and supplying blanks at accurate positions. can. At the same time, since part of the blank load is supported by the claw members of these devices, the load on the quantitative holding device can be reduced.

Further, since the direction of at least the claw member on the centering device side can be changed depending on the form of the blank, it is possible to stably hold a blank with a complicated form, and it is possible to dramatically improve the expansion and usability of the target blank.

Therefore, from the replenishment position C, the lifter 62. Transfer device 61
The blank W supplied using the blank W is lifted upward in the figure by the lift cylinder device 63 and aligned by the cooperation of the front stopper adjusting device 10 and the centering device 30. Thereafter, the samples are held in a quantitative holding device 70 and separated one by one by a separating device 80. The separation device 80 of this embodiment includes a plurality of magnets 81
It is formed by including.

The uppermost blank W that has been magnetically separated is attracted by the vacuum cup of the suction device 91 that has descended, and is pulled up to the conveyance line L. Here, the two-sheet detection device 92 is activated to check the number of blanks that are being sucked.

If it is one sheet, it is pitch-transferred to a transfer press 100 (in the figure, 101 is a transfeed means, 102 is a mold, and 103 is a bolster) by an intermediate conveyance means 94.

In other words, the intermediate conveying means 94 moves the blank W that was sucked by the suction device 91 and the elevating body 96 that moves the movable body 95 that reciprocates with a constant stroke and the vacuum cup 97 up and down between the conveyance line L and the holding member 99, and the suction device 91. It is composed of gripping jaws 98 and the like. Therefore, each idle stage center P2 . P3. Blanks W can be conveyed at a predetermined pitch for each P4. It is transported from the i&final idle stage P5 to the press first stage center S by the transfer feed means 101.

Here, the technical features of the distack feeder 60 according to the present invention are as shown in FIGS. 1 to 9, as shown in FIGS. The front stopper 11 and the centering device 30 are arranged to face each other in order to avoid collision with the quantitative holding device 70 etc. and to prevent damage to these devices, and the front stopper 11 and the centering device 30 are each provided with a quantitative holding device 70 (claw member 71
) is provided to reduce the load on the quantitative holding device 70 (claw member 71), and a claw member 35 for securely holding the target blank is provided. It is attached to the centering device 30 so that its direction can be changed within a horizontal plane.

In addition, in order to further demonstrate and effectively utilize the above-mentioned functions, as shown in FIG. The configuration is such that a lateral force is applied to a plurality of blanks W that are held in a manner that they can be approached separately from the center P1 to eliminate misalignment of the blanks, and that a separating device 80 having a strong magnet 81 can be set quickly and accurately. .

Furthermore, the front stopper 11 forms a part of the front stopper adjusting device 10 in order to be able to adjust its position with respect to the distack center P1, and the front stopper 11 has a structure that can withstand a predetermined collision force. , it is possible to horizontally transport a plurality of stacked blanks W by the transfer device 61, and it is also possible to improve the positional accuracy of the plurality of blanks W with respect to the distack center P1.

The main components will be separated below.

The front stopper adjustment device 10 is shown in FIGS. 1 and 5 to
As shown in FIG. 7, the structure is roughly divided into a pressing member 12, a claw member 16, a drive control mechanism, and a pressure receiving means attached to the machine frame 29-1.

That is, the pressing member 12 is located at the distack center (position f).
) is erected parallel to Pi, and its surface forms a front stopper (reference surface) 11 and also serves as a quantitative holding device 7.
0 (as shown in FIG. 11, eight claw members 71), a portion 12U protrudes above it. However, this portion 12U can be separated from the lower side (12D) for manufacturing convenience.

The front stopper 11 has the role of colliding the front ends of the stacked blanks that are transferred laterally by the transfer device 61 and regulating the position of the blanks W with respect to the distack center P1, and therefore receives the pressure of the collision force. A cylinder device 28 is provided as a means. Cylinder equipment! 28 is a bracket 2 integrated with the machine frame 29-1.
It is attached to 9-2. Also, a contact detector 1 detects that the blank W collides with the front stopper 11.
An actuation bar 15 is provided for actuating 5D. The operating bar 15 is rotatably mounted on the support shaft 13 of the pressing member 12, and its lower end projects leftward in the figure from the front stopper 11.

The amount of protrusion is regulated by a spring and stop bin 14 (not shown).

Furthermore, the claw member 16 is formed to reduce the load on the quantitative holding device 70 and to be able to collect the plurality of blanks W left in the quantitative holding device 70 when there is a change in the production plan or the like. has been done.

That is, the claw member 16 has the same form as the claw member 71 forming the quantitative holding device 70 as shown in FIG.
It is rotatably attached to the pressing member 12 via a support shaft 19 . Further, it is urged by a spring 18 and locked by a limit bin 17 so as to be in a predetermined position. Further, the distal end side of the claw member 16 projects further toward the distack center P1 than the front stopper 11, and the upper surface thereof is horizontal. Therefore, in FIG. 1, the plurality of blanks W pushed up from below are further pushed up while rotating the claw member 16 clockwise against the biasing force of the spring 18. Then, the blank W is supported by the claw member 16 which has returned to the predetermined position due to the biasing force of the spring 18. That is, the claw member 16
is attached to the pressing member 12 using an anti-back method.

Here, as shown in FIG. 11, four sets of claw members 16 are provided.

As shown in FIGS. 5 to 7, the drive control mechanism positions the front stopper 11 at a desired position in the direction of the distack center P1, and as shown in FIG. Drive is controlled by forward and backward movement.

Each screw 25 is driven by a female screw rotating body 22 which is rotatably mounted on the brackets 2-2. Both male screw rotating bodies 22,22 are synchronously rotated by a chain 24 stretched across a sprocket 2323. The drive source is a motor 20 connected to a female threaded rotating body 22 on the lower side in FIG. 1 via a gear a side 21. Each screw 25 is connected to the pressing member 12 via a spherical bearing 27. In addition, 2
3 is an optical disc for detecting the feed amount.

Therefore, the screw 25 can be moved forward and backward by controlling the rotation of the motor 20 using an appropriate control circuit (not shown) and rotating the double male screw rotating body 22 via the gears 8i42i and the like.

The amount of displacement in forward and backward movement is accurately controlled by feeding back the amount of rotation from the optical disk 23 to the control circuit.

Here, the drive control mechanism can quantitatively move the front stopper 11 forward and backward relative to the bracket 292 that is a part of the machine frame 29-1.

In addition, when a large forward and backward movement is required, the machine frame 29-1 itself can be moved and fixed relative to the machine body (rail 2) via the wheels 3.3. In other words, the rough position with respect to the machine body is determined by the fixed position of the machine frame 29-1, and the position of the front stopper 11 with this machine frame 29-1 (bracket 29-2) as a position reference is determined by @adjustment of the drive control mechanism. This is the configuration that will be used.

Next, the centering device IL30 is shown in FIGS.
As shown in FIGS. 8, 9 and 11.

The base body 43 is reciprocatably mounted on the rail 2 via wheels 3.3. A pressing member 32 is provided at the front end portion of this base body 43. The pressing member 32 is divided into two parts, an upper part 32U and a lower part 32D, which protrude above the fixed quantity holding device 70, in order to provide a strong function.

First, the entire pressing member 32 is moved forward and backward by rotating a screw 41 mounted on the body by a motor 39 via a gear mechanism 40.

Rotation control of the motor 39 is performed by a control circuit (not shown) (equivalent to the control circuit of the front stopper adjustment device 10), and is controlled by feedback using an optical disk 42.

Therefore, if the control circuit controls the reciprocating movement of the body 43, the upper part 32U (pressing surface 31U) forming the pressing member 32
) can only be positioned.

On the other hand, the lower portion 32D can reciprocate with respect to the base body 43 by a fixed stroke. That is, the lower part 32D is supported by a pair of guide rods 47, 47 that are slidably guided by the base body 43, and is supported by the cylinder device 44 (cylinder 45, rod 46).
) is driven by.

Here, the lower part 32D (pressing surface 31D) of the pressing member 32 cooperates with the front stopper 11 to apply a lateral pressing force to the blank W before supplying the blank W to the quantitative holding device 70, and presses the blank W against the table. Blank W on 64
This is used when adjusting the posture of the meter, that is, the position relative to the quantitative holding device 70.

The upper part 32U (pressing surface 31U) is a strong magnet of the separation device 80 that applies a lateral force to the plurality of blanks W supported by the quantitative holding device 70 in cooperation with the upwardly projecting portion 12U of the pressing member 12. This is to prevent the blank W from shifting when setting the blank W.

The pressing member 32 also includes a spring 37 and a limit pin 36.
A claw member 35 whose position is regulated by the claw member 35 is provided.
is rotatably attached to the support shaft 38.

This claw member 35 is formed of an anti-back type like the claw member 16 of the front stopper adjustment device 10, and is of the eleventh
As shown in the figure, two sets of claw members 7 of the quantitative holding device 70
1.71.

Here, the claw member 35 is attached to the centering device 30 (pressing member 32U) so as to be able to change its direction in a horizontal plane via an angle adjustment means 48 whose details are shown in FIG. Note that in FIGS. 8 and 9, the angle adjustment means 48 is omitted for convenience of explanation.

That is, in order to mechanically position a plurality of blanks W transferred laterally by the transfer device 61 by colliding with the front stopper 11, the transfer posture of the blanks W must be determined. For example, as shown in FIG. If the blank W is in such a form that the straight portion S is moved toward the front stopper 11 side.

Therefore, since the claw member 35 on the centering device 30 side corresponds to the inclined portion, the blank W cannot be held effectively in many cases.

The angle adjusting means 48 provided to solve this technical problem is constructed as shown in FIGS. 2 and 3.

In FIG. 2, the claw member 35 is provided on a rotating body 48E via a support shaft 38, and a handle 48A is directly connected to the rotating body 48E via a shaft 48B. Furthermore, a plurality of holes 48G are provided at the upper part of the shaft 48B and are arranged at equal angles around the circumference. A lock pin 48D is inserted into this hole 48C.

Therefore, pull out the lock pin 48D from the hole 48C,
By rotating the rotating body 48E with the handle 48A, the direction of the claw member 35 can be changed within the horizontal plane. The set angle is locked by inserting the lock pin 48D into the hole 48C. In addition, in this embodiment, seven holes 48C are provided so that the angle can be set to 0 degrees, 30 degrees, 45 degrees, and 60 degrees.
has been established.

Further, as shown in FIG. 11, the separating device 80 in this embodiment includes a total of eight magnets 81, 81. . . , each magnet 81 is movable forward and backward from each base 83, and has a handle 84. An angle setting mechanism 82 including a bevel gear 85 etc. allows the shaft 86 to be
It is rotated around , and is formed to be set at an angle according to the contour of the blank W.

Therefore, each magnet 81 is set in advance to match the contour of the blank W, and then each magnet 8
1 to the blank W, and then each magnet 8
Setting of the separation device 80 is completed by retracting the separation device 1 by, for example, 7 mm and locking the separation device 80.

On the other hand, the fixed quantity holding device 70 supports and places a predetermined amount (number of blanks) W in the separation device 80, and is attached to the holder of each magnet 81 so as to protrude from the surface of each magnet 81. There is.

As shown in FIG. 1, this device 70 includes a claw member 71, a support shaft 74 that rotatably supports the claw member 71, and a claw member 35.
It is formed of a spring 73 and a limit pin 72 for maintaining a predetermined posture, and the same number of magnets 81 are provided.

Such claw members 71 and the like are attached to the front stopper adjusting device 10.
and the pawl member 3 of the centering device 30.
5 etc., and each claw member 16, 35.71
are installed so that they are at the same height.

[Effect] The operation of this embodiment will be explained below.

First, the reference plane of the front stopper adjusting device 10, that is, the position of the front stopper 11 is set.

The set position is such that when the tip (straight portion S) of the blank W transferred laterally by the transfer device 61 comes into contact with the front stopper 11, the blank W is at a predetermined position with respect to the distack center P1. Selected.

Here, when the plurality of transferred blanks W come into contact with the front stopper 11, the contact detector 15D is activated to stop the transfer device 61. Therefore, multiple blanks W
is stopped at a predetermined position relative to the distack center P1. Here, a plurality of blanks W can be supplied to a predetermined position in a stacked state without using a pallet.

Next, the lift cylinder device 63 is activated, and the table 64
to adjust the multiple blanks W to the position (in Figure 1, the two-dot chain line indicates Wl).
).

Subsequently, the cylinder device 44 of the centering device 30 is activated to push the pressing member 32D to the right in FIG. 1, and apply a lateral force to the plurality of blanks W1 on the table 64 with its pressing surface 31D. The attitude of the blank W1 is corrected between it and the front stopper 11. Thereafter, the cylinder device 44 is returned to its original position.

Furthermore, the table 64 is pushed up by the lift cylinder device 63. The uppermost part of the plurality of blanks or the claw member 71 of the quantitative holding device 70 is rotated about the support shaft 74. The pawl member 16 of the front stopper adjusting device 10 and the pawl member 35 of the centering device 30 are also rotated in the same manner. Further, the table 64 is pushed up, and it is confirmed that the lowest position of the plurality of blanks has reached above each claw member 71, 16, 35, and then the table 64 is pulled down.

Here, the multiple blanks are W2 shown by the two-dot chain line in Figure 1.
4, that is, each claw member 16. is held by the quantitative holding device 70 and does not fall downward.
35 reduces the load on the quantitative holding device 70, and
Effective for stably holding blanks with complex shapes.

That is, it is assumed that the angle of the claw member 35 of the centering device 30 is set by the angle adjustment means 48 according to the form of the blank. That is, as shown in FIG. 4, by changing the orientation in the horizontal plane, it is possible to stably hold blanks in a plurality of shapes.

Then, by controlling the motor 39 of the centering device 30, the pressing member 32U is further pushed slightly and accurately toward the destacking center P1, and the plurality of blanks W2 are pressed against a portion 120 of the front stopper 11. Multiple blanks W
2 is clamped and fixed in position between the portion 12U and the pressing member 32U. All or part of the plurality of blanks W2 will not be displaced in the horizontal direction due to at least other external forces.

In this state, the separation device 80 is set.

That is, each magnet 81 whose angle has been adjusted in advance is once brought into contact with the blank W2, and then retreated from this state by, for example, 7 mm. Therefore, each magnet 81 has an equal gap of 7 mm with respect to the blank held in the metering bold device 70.

In this case, even if the magnetic force of each magnet 81 is large, the position of the blank will not shift. Subsequently, when the pressing member 32U is pulled back away from the blanks by the motor 39, the plurality of blanks are magnetically separated by the separating device 80.

Then, the separated uppermost single blank is placed in the adsorption device 9.
1 and delivered to the intermediate conveyance means 94.

Note that the blank held by the quantitative holding device 70 is
Before the front stopper 11 part 12U and the pressing member 32 part 32U are clamped together by a lateral force, the vacuum cup of the suction device 91 is lowered as before, and the table 64 is raised to blank the part 12U by a vertical force. You can hold it down.

According to this embodiment, the front stopper adjustment device 10 (front stopper 11) and the centering device 30 are arranged to face each other, and the positions of the plurality of blanks W are regulated or adjusted before being supported by the quantitative holding device 70. Since the configuration is such that the blank W and the quantitative holding device 70
Collisions with other objects are prevented and blanks can be fed smoothly.

In addition, the front stopper (reference surface) 11 and the pressing member 32
Both U (suppression surface 31U) are at the distac center P1.
Since it is formed so that it can be moved away from and approached, and the position of the blank can be corrected between the transfer device 61 and the quantitative holding device 70, the quantitative holding device 70 and the separating device 80 can be attached to the frame for each blank as in the past. This eliminates the trouble of fixing the frame to a blank and replacing the frame depending on the blank, and the duplication of equipment, and provides wide flexibility to supply a wide variety of blanks.

Also, a pressing member 12 (front stopper 11).

Since the pressing member 32 (32U) is provided with the claw members 16.35, not only can the load on the quantitative holding device 70 be reduced, but also irregularly shaped blanks can be held stably.

In particular, since the claw member 35 is attached to the centering device 30 (pressing member 32U) so as to be able to change its direction within the horizontal plane, the angle can be adjusted according to the shape of the blank, even if the blank has a complicated shape. The quantitative holding device 70 (claw member 71) can be held securely, the number of installations, etc. is likely to be limited, and the drawbacks of the quantitative holding device 70 (claw member 71) can be compensated for, and the quantitative holding device can be simplified.

Further, a portion 12U of the front stopper 11 and a portion 32U of the pressing member 32 are configured to protrude above the fixed amount holding device 70 (claw member 71), and each portion 12U
Since U and 32U are configured to be able to approach and separate from the distack center, the blanks held in the quantitative holding device 70 can be moved without being affected by the strong magnetic force of the magnet 81.
Can be held stably. Therefore, separation equipment! 80 settings can be made quickly and accurately.

In addition, the front stopper adjustment device 10 can minutely and accurately position the front stopper 11 by controlling the motor, and can also adjust the assembly position relative to the machine body (rail 2) via the wheels 3. can also be applied. Moreover, the cylinder device 28 as a pressure receiving means
is provided, so the stacked blanks W can be transported as they are without the pallet and can be accurately positioned. This makes it possible to further simplify the control equipment and the like around the transfer device 61 and the distack center 21, and to reduce the setting space.

Furthermore, the centering device 30 has five pressing members 32 (3
2U, 32D) can be precisely and minutely positioned by motor control, and only the lower suppressing member 32D can be moved in and out by a predetermined stroke using the cylinder device 44.
It is possible to efficiently regulate the position of the blanks prior to supplying them to the fixed quantity holding device 70 and to prevent blanks from shifting during the setting of the separation device 'f180.

Furthermore, the claw members 16.35 of the front stopper adjusting device 10 and the fixed amount holding device 70 are attached to the magnet 8.
Claw member 7 of quantitative holding device 70 that moves forward and backward together with 1
Since it is possible to hold a plurality of blanks in an appropriate amount instead of 1, by reversing the above procedure, the blanks W, which were initially supported by the quantitative holding device 70, can be placed on the table 64 again and recovered to the transfer device 61. can.

Note that the pressing member 12 forming the front stopper 11 of the front stopper adjustment device 1O was integrally molded, but
The pressing members 32 of the centering device 30 are 32U and 32D.
In the same way as when it was formed in a split mold with
D) and the upper portion 12U may be constructed as a separate type, or it may be implemented that the pressing members 32U and 32D are integrally constructed.

Of course, the claw member 1 of the front stopper adjustment device 10@
6 can also be easily formed to be changeable in direction like the claw member 35 on the centering device 30 side.

[Effects of the Invention] As is clear from the above description, the present invention regulates the position of a plurality of blanks using a centering device that cooperates with a front stopper, and then supplies them to a quantitative holding device, and provides claw members on the front stopper and the centering device. In addition, the claw member on the centering device side is installed so that its orientation can be changed within the horizontal plane, making it possible to supply multiple blanks without damaging the equipment, reducing the load on the metering holding device, and making it possible to handle complex configurations. It has an excellent effect of being able to securely hold the blank and achieve quick and smooth data stack feeding.
