Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a material supply / processing apparatus for a press machine capable of automatically supplying a material piece at a high speed to a press machine for punching a plate material into a required shape and discharging the material piece.

[0002]

2. Description of the Related Art Conventionally, the press work obtained by punching a product of a required shape or an intermediate product from a flat plate material piece cut to a required size is almost always done by a worker except for a large press machine equipped with a transfer feeder. The current situation is that supply of materials and discharge of scrap materials after punching are being performed.

To describe an example from the supply of the material piece to the press machine to the post-treatment, an operator of the press machine firstly cuts the material piece into a required size by an electromagnet provided on the bed of the press machine. Appropriate amount of material is piled up at the place where the applied iron plate separator is placed so that the material pieces are separated one by one. Next, this separated piece of material is manually placed on the die upper surface of the press at a predetermined position, and then the upper die of the press is operated for one stroke to punch a product from the piece of material. The punched product is dropped and received by a product receiving portion provided below the lower die mounting position. The frame-shaped scrap pieces after the product has been punched are removed before the next piece of material is placed on the die top surface. The frame-shaped scrap pieces are piled up in appropriate places on the bed of the press machine, and when the frame-shaped scrap pieces are collected, they are transferred to a scrap container or the like. Similarly, when the product is accumulated in an appropriate amount, it is taken out from under the lower die mounting portion and transferred to a pallet or the like for transportation so that it can be easily transferred to the next step. One press worker does more than usual.

Recently, there has been an attempt to adopt a transfer robot in order to rationalize such manual work. Further, a method of using a fixed-length feeding device in combination is also known.

[0005]

When the above-mentioned manual supply of the material pieces to the processing of the product after press working and the processing of scraps are carried out, the material pieces can be handled by hand depending on the size and weight of the material piece. Since it will be taken and handled by us, productivity is usually about 30 hours when operating for 8 hours a day.
Processing of 00 sheets (about 6000 Kg) is the limit.

Moreover, since the work height for hand-replacement of the material pieces changes, the worker becomes stiff during standing work and frequently moves an article having the above-mentioned weight, which necessitates heavy work. Conventional transfer robots and automatic supply / transfer devices that try to relieve workers from such heavy labor and improve productivity require repetitive motions. There is a limit to the operation speed for surely transferring the conveyed product, the material supply speed is substantially slow, and the work capacity is naturally low.

The present invention aims to solve such a conventional problem, and is capable of supporting continuous operation of a press machine, and supplies a material piece in conjunction with the vertical movement of a slide having an upper die holder. Another object of the present invention is to provide a material supply processing device for a press machine capable of automatically discharging punched products and punching scraps.

[0008]

In order to achieve the above-mentioned object, the present invention has the following advantages: (a) A stacked material piece is installed in a frame installed on the side of a press so that the stacked material pieces can be adjusted to the feeding speed. A material receiving and supplying means having an elevating and lowering support which is sequentially lifted up and having a separating mechanism for separating the sheets one by one, (b) a material separated by the separating mechanism above the material receiving and supplying means A material piece adsorbing and lifting means for adsorbing and holding one piece to a required height, and (c) a material piece adsorbed and lifted by the material piece adsorbing and lifting means,
Material piece striking means for striking from the side end to the press machine side and flying and transporting it on the supply path, (d) this material piece striking means is operated in a predetermined order in conjunction with the elevation of the upper die holder of the press machine As described above, the operating means connected to the upper die holder of the press machine, and (e) the material piece feeding process by the operating means, the material piece blown by the material piece striking means is placed at a predetermined position on the lower die of the press machine. A material supply processing device for a press machine, comprising: a material piece receiving means for a press machine, which has the supply path for guiding up to and a sensor for detecting completion of supply of the material piece.

Further, according to the present invention, the above-mentioned material receiving / supporting supply means, material piece suction lifting means, material piece striking means, operating means, and material piece receiving means for the press machine are further provided, and the lower die of the press machine is further provided. , A pair of guide bars that lift the scraps to the outside of the machine and eject them to the outside of the machine, a cam that tilts the guide bars, and a fluid pressure cylinder that operates the cams. It is preferable to provide a scrap discharging means composed of a positioning guide plate for temporarily applying a protruding reaction force.

[0010]

According to the present invention having such a configuration, when the material pieces having a required size are stacked and received on the elevating and lowering support of the material receiving and supplying means and the press machine is operated, the upper die of the press machine is operated. The vertical movement of the holder is directly transmitted to the operating means, and the operation of the operating means causes the material piece lifted by the material receiving and supplying means to be moved by the material piece suction lifting means to 1
The pieces are lifted one by one, and are struck laterally by the interlocking material piece striking means to move forward from the suction state (press machine side).
The material piece is skipped, moved and dropped on the supply path, transferred to the lower position of the press machine as it is, and when the acceptance of the material piece is confirmed by the sensor attached to the position, the product is punched, These operations are automatically and continuously operated.

Further, in the present invention, by providing the scrap discharging means as described above, after the material pieces are supplied as described above and the punching operation is performed by the press machine, the upper die of the press machine is lifted. The scrap pieces after punching the product from the material pieces are immediately pushed up and simultaneously ejected to the discharge side so that they can be promptly removed to the outside of the machine, so that everything from supply to discharge is automatically performed. As a result, the press punching work is continuously performed without human intervention, so that workability can be improved and safety can be secured at the same time.

The material piece striking means 30 and the material receiving means 50 that guides and receives the material piece B which has been transported in flight from the supply path 51 to a predetermined position of the lower die 4 of the press machine 2. In addition,
The positional relationship between the press machine 2 and the material supply processing apparatus 1 is preferably arranged as close as possible to the side of the frame of the press machine 2.

The support frame 11 is formed in a vertically long frame structure with a space in which material pieces B having a required size can be vertically stacked and raised. An opening is provided on the side of the press 2 at a position slightly higher than the upper surface of the lower die 4 of the press 2 in the middle of the support frame 11, and a feed path having a downward slope from the opening to the upper surface of the lower die 4 of the press 2. 51 is erected. It should be noted that the supply path 51 is provided with a large number of rolling elements (for example, rollers) arranged on the upper surface.

The operation lever 17b provided with the feed claw 17a is kept constant when a material piece acceptance detection signal is transmitted, for example, 3 to 4 times from a sensor 45 (see FIG. 3) arranged near the lower die of the press 2. The operation cylinder 16a which is reciprocated a distance causes the ratchet gear 17 to rotate at a constant rotation angle and is gradually rotated by a lifting drive mechanism 16, which causes the wire rope 13 to rotate.
Is wound up to raise the lifting support 12.

In order to lower the elevating support 12, the feed claw 17a of the lifting drive mechanism 16 and the ratchet gear 17 are disengaged from each other, and a handle wheel attached to the end of the support shaft 15a of the take-up reel 15. This can be done by unwinding the wire rope 13 from the take-up reel 15 by reverse rotation (not shown).

A plurality of known electromagnetic separators 18 corresponding to the outer shape of the material piece B are disposed on the upper portion of the material piece receiving / supporting and supplying means 10 having such a structure, and are mounted on the elevating support body 12. The material pieces B which are piled up and raised are released one by one by the electromagnetic separator 18 at the upper portion and are raised.

The material piece adsorbing and lifting means 20 includes a support rod 21 which is supported at the upper position of the support frame 11 so as to be vertically movable with respect to the material piece B which is raised by the material receiving and supplying means 10. A plurality of attraction pieces 23 (permanent magnets) are attached to the lower surface of a holding plate 22 attached to the lower end of the support rod 21, and a roller 24, which is a vertically movable operation piece attached to an intermediate position of the support rod 21, is used. It is configured to be moved up and down by the operating means 40.

The material hitting means 30 has a base end supporting frame.
Mainly is a striking lever 31 pivotally supported on the upper part of 11 by a pin 33, and a cam surface 32 having a concave curved surface is formed in a curved intermediate portion, and a cam lever 35 of an operating means 40 is provided with respect to the cam surface 32.
The cam follower 36 at the tip comes into contact with the cam follower 36, and the displacement of the cam follower 36 causes the striking lever 31 to strike. The striking part 31 'at the tip of this striking lever 31
Is formed in a concave shape capable of applying a lateral striking force to the side end of the material piece B in a state of being sucked by the suction piece 23 of the material suction means 20 and being lifted to the uppermost position. Then, the middle portion of the striking lever 31 and the support frame

Pins 44 are connected to each other. One of the connecting portions of the cam lever 35 and the operation arm 41 is formed in a long hole.

Further, a sensor 45 for detecting whether or not the piece of material to be processed is received is provided at a proper position adjacent to the upper surface of the lower die 4 in the press machine 2. The sensor 45 detects the reception of the piece of material. The signal is counted by a control mechanism (not shown), and is associated with, for example, every three to four times, the operation cylinder 16a in the lifting drive mechanism 16 of the material piece supporting / feeding means 10 is moved up and down once by a predetermined stroke. ing. The operation of the operating cylinder 16a raises the lifting support 12 as described above.

Scrap discharge means 60 is attached to the periphery of the lower die 4 of the press machine 2 and the side portion adjacent to the lower die 4 except the material piece supply side, preferably the rear side. As the scrap discharge means 60, as shown in FIG. 3, a plurality of guide rollers 61a are provided so that the scrap pieces C can be discharged from above the lower mold 4 to the discharge side (front side in this specific example).
Guide bars 61, 6 that are arranged with part of them protruding to the upper surface
1'is arranged on both sides of the lower mold 4, and both guide bars 61, 61 '
Is mounted on the die surface plate with a hinge 61c on the downstream side of the discharge, and a tilting cam is provided on the upstream end side of the guide bars 61, 61 '.
61d and 61d are formed.

On the upstream side of these guide bars 61, 61 ',
A cam 63 'for lifting and tilting the guide bars 61, 61', which are operated to move forward and backward by the fluid pressure cylinder 62, in the flow direction.
63 'is attached to the forward side of the operating member 63. Further, the operating member 63 is provided with a projecting piece 63a which comes into contact with the end of the scrap piece C by the forward movement of the fluid pressure cylinder 62 and kicks out the scrap piece C in the flow direction of the scrap piece C. Furthermore, a positioning guide plate 64 for the piece of material B pivotably attached to the lower part is arranged at a downstream position between the guide bars 61, 61 '. The positioning guide plate 64 is always biased to a tilted state by a pulling spring 65, and a cam piece 64a is attached to one side end of the positioning guide plate 64 in the width direction. The cam piece 64a is in contact with the tip cam 66 'of the cam lever 66 which is arranged along the guide bar 61 and whose rear end is connected to the operating member 63, and the positioning guide plate 64 is normally erected. ing.

In the cam lever 66, the tip end of the cam 66 'is gradually tilted by the forward movement of the cam lever 66 via the cam piece 64a in the required section, and the cam 66' is moved.
Positioning guide plate 64 at the position where the rear end is separated from cam piece 64a
Is formed to tilt. Incidentally, reference numeral 67 in the figure
Is a stopper, 68 and 68 'are guide plates, and 69 is a fixed positioning guide plate, which is supported by the lower die mounting plate. Further, the tilting direction of the positioning guide plate 64 can be tilted forward or backward as required.

In the material supply / processing apparatus of the present invention thus constructed, the elevating / lowering support body 12 of the material receiving / supporting / supplying means 10 is lowered, and the preset outer dimensions (constant size) are set on the elevating / lowering support body 12. When the press machine 2 is driven by stacking a required amount of the material pieces B (which are aligned with each other), and the press machine 2 is driven, the material piece B is connected to the side connecting part 43 of the upper die holder 3 of the press machine 2 with a fixed connecting piece 43. The operation arm 41 is vertically swung with the pivot pin 42 with respect to the support frame 11 as a base point.

When the operation arm 41 descends, FIG. 5 (b)
As shown by, the cam lever 35 connected to this operation arm 41 via the pin 44 at the intermediate position has the pin 3 of the pivot point.
5'is used as a fulcrum to rotate downward, and via the roller 24 in contact with the cam lever 35, the material piece suction lifting means 20
The holding plate 22 is lowered, and the adsorption pieces 23 attached to the lower surface of the holding plate 22 are stacked on the elevating support 12 and separated by the electromagnetic separator 18 into pieces one by one. Then, one piece of the material piece B is adsorbed and held. Immediately before the suction holding operation of the material piece B is performed, the cam lever
As the cam follower 36 at the tip of 35 descends, the cam surface
The striking lever 31 which is curved via 32 is retracted. Therefore, the striking lever 31 does not interfere with the lowering of the holding plate 22 of the material piece suction lifting means 20.

When the upper die holder 3 of the press 2 shifts to the ascending stroke, the operation arms 41 to be connected together start to rotate upward, and the upward rotation of the operation arm 41 also causes the cam lever 35 to rotate upward. By this cam lever 35, the holding plate 22 holding the material piece B by suction is also pulled up via the roller 24. Of course, the cam lever
35 Displacement of cam follower 36 at the tip 36 Strike lever 31
Moves in the forward direction.

Immediately before the upper die holder 3 of the press 2 reaches the upper limit position in the ascending stroke, as shown in FIG. 5 (a),
When the holding plate 22 for sucking and holding the material piece B approaches the upper limit position, the striking portion 31 ′ of the striking lever 31 is aligned with the upper limit position to the side end of the material piece B sucked and held by the holding plate 22. Abut. Since these operations are performed within a short time, the side end of the material piece B is substantially hit by the hitting portion 31 'of the hitting lever 31. Since the material piece B is attracted by the plurality of magnet pieces 23 attached to the holding plate 22 as described above, strong attraction and holding is performed in the vertical direction, but the holding force is weak in the lateral direction. , When it is hit, it slides on the suction surface and moves forward (press machine 2
Since the material piece B is a flat plate, it will fly to a position near the lower mold 4 of the press machine 2 on the supply path 51 and drop, because the material piece B is a flat plate.

The material piece B dropped onto the supply path 51 has a supply path surface provided with a plurality of rollers forming the supply path 51, which is formed in a downward slope toward the lower die 4 of the press 2.
Further, since it is provided with a guide, it is slid as it is due to the inertia when dropped and is supplied to a predetermined position on the lower mold 4. When the material piece B is received at a predetermined position of the lower die 4, a sensor 45 for confirming the acceptance of the material piece B is detected, and a material piece acceptance signal is sent to a control mechanism (not shown) of the press machine 2 and the material supply processing apparatus 1. Is transmitted, the press machine 2 continues to operate. Therefore, the upper die of the press 2 is lowered and the product is punched from the material piece B. During this period, the next piece of material B is in a state of being adsorbed and lifted by the piece of material adsorbing and lifting means 20 in the same manner as described above, and the striking lever 31 of the piece of material striking means 30 retracts to strike the next piece of material B. Becomes

In the press machine 2, when the punching operation of the product is finished, the upper die rises, so that the punched scraps (scrap pieces C) in a frame shape after the product is punched out,
The scrap is discharged by the scrap discharging means 60. In the operation of the scrap discharging means 60, the upper die starts to move up by a command from a control mechanism (not shown), the pressing force against the upper surface of the scrap piece C is removed, and at the same time, the fluid pressure cylinder 62 operates to move the operating member 63 forward. . Then, the lower mold 4 is moved by the cam pieces 64a, 64a attached to the operating member 63.
Cam 61 at the upstream end of the guide bars 61, 61 'located on both sides of the
When d and 61d are operated, both guide bars 61 and 61 'are lifted with respect to the discharge downstream side and are inclined (see FIG. 4).

Simultaneously with this operation, a thrust force in the discharge direction is applied to the discharge upstream end of the scrap piece C by the protruding piece 63a attached to the operating member 63. At this time, the discharge downstream side of the scrap piece C is received by the positioning guide plate 64 when the material piece B is supplied, and the positioning guide plate 64 is also received.
A cam piece 64a attached to one end of the cam 64 is connected to the operation member 63.
As a result, the scrap piece C is gradually tilted toward the front side (discharging upstream side), and a reaction force corresponding to the thrust in the discharging direction by the projecting piece 63a is applied to the scrap piece C. As a result, scrap piece C
Is gradually lifted by the contact resistance with the positioning guide plate 64, and eventually the cam 66 'at the tip of the cam lever 66 and the cam piece 64a.
When the displacement in the contact state with the scrap becomes large, the scrap piece C is repelled by the stress, and the scrap spring passes over the positioning guide plate 64 largely tilted forward by the force of the pulling spring 65 and is discharged onto a scrap discharge path (not shown) that is arranged in advance. And sent into a scrap stocker (not shown).

In this way, when the scrap piece C is discharged, the fluid pressure cylinder 62 is immediately retracted by the command of the control mechanism and returned to the original positions of the guide bars 61, 61 'and the cam lever 66, and Then, the positioning guide plate 64 is also returned to the upright state, and the next material piece B is received on the lower mold 4. Since the punched product is punched to the lower side of the lower die 4 and drops at the same time, if the product is slid down into a stocker (not shown) to be received, the product can be conveniently transported.

As described above, the material piece B is supplied to the press machine 2, and the punched product and the scrap piece C are discharged while the upper die of the press machine 2 shifts to the ascending stroke. On the other hand, the material piece adsorbing and lifting means 20 moves to receive the next material piece B, and the material piece striking means 30 shifts to the striking standby state, and thereafter, the punching work is repeated in the same manner as described above. While such an operation is being performed, in the material receiving and supplying means 10, for example, the material piece B is 3 to 4 pieces.
When the sheets are supplied, as described above, the operation cylinder 16a of the lifting drive mechanism 16 is reciprocated for a required stroke by the command signal from the control mechanism, and the operation lever 17b swings, and is attached to the operation lever 17b. The feed gear 17a rotates the ratchet gear 17 by a predetermined rotation angle. The take-up reel 15 is operated via the support shaft 15a of the ratchet gear 17 in the winding direction of the wire rope 13 for suspending the lifting support 12. Therefore, every time 3 to 4 pieces of the material pieces B are supplied, the material pieces B loaded on the elevating / lowering support body 12 are lifted up, and the material pieces B are lifted in the range of raising and lowering the holding plate 22 of the material piece suction lifting means 20. It is surely adsorbed, lifted and supplied.

It should be noted that although not shown, a limit switch is provided in advance so as to stop at the upper limit when the elevating support 12 is raised to the maximum, and the supply operation is stopped by this limit switch. Further, in order to restart the supply of the material pieces, it is sufficient to lower the elevating / lowering support 12 and stack a new required amount of the material pieces B to activate the material pieces.

As described above, according to the material supply processing apparatus for the press machine of the present invention, when supplying the material pieces,
Since the materials picked up and picked up one by one are struck from the side and blown to the vicinity of the supply target position to be supplied, it is possible to omit the retreat of the conveying means when conveying the material pieces. Therefore, since the material can be supplied in synchronism with the operation of the press machine, it is possible to follow the working capacity of the press machine, and it becomes possible to perform punching work at a high speed which has not been predicted previously. By the way, if the operation example is increased, it is possible to supply a steel plate of 500 × 300 mm and a thickness of about 2 mm at 30 to 50 sheets / min.

[0037]

As described above, according to the present invention, it is possible to perform the punching press work by supplying the material to the press machine at a high speed with a simple structure, and it requires manpower except for supplying the material. It is possible to automate the process from material supply to product removal with high efficiency. Further, since it is not necessary to manually place scraps of materials and products as well as scraps, safety is enhanced, and labor saving and rationalization of this kind are promoted.
