Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a device that separates laminated plates one by one. The present invention relates to a device for separation.

[Technical background of the invention and its problems]

For example, a device for separating sheets stacked on a pallet one by one is generally equipped with suction attachments such as vacuum parts or electromagnets at the lower ends of a plurality of support rods that are hung vertically on a lifter frame that can be raised and lowered. It is what it is. Since all the suction attachments mentioned above are placed at the same height,
In the case of a plate material whose top surface is horizontal, it can be adsorbed without any problems. However, when plate materials with uneven parts such as burring or louvers applied to one part are laminated using a plate processing device such as a pallet punch press, the plate materials may be curved due to the level difference in the uneven parts. Due to the above-mentioned unevenness, it has been difficult in the past for all types of suction attachment to suction the plate material.

It is comprised of a transfer device 7 that transfers the separated plate material S to a predetermined position.

The board support device 5 includes roller conveyors 11 on both sides that movably support both sides of a pallet 9, which serves as a mounting table on which the stacked boards S are placed and supported.
and a lifter device 13 that supports the pallet 9 between both roller conveyors 11 so as to be able to move up and down. This lifter device 13 has the function of pushing up the pallet 9 in order to keep the height position of the top of the plate material S stacked on the pallet 9 almost constant at all times. Lifter device 13
is equipped with a horizontal table 15 that supports the pallet 9 from below, a cross link mechanism 17 for moving the table 15 up and down, and a hydraulic cylinder (not shown) for operating the cross link mechanism 17. . Since the configuration and operation control of this type of lifter device are common, detailed explanation thereof will be omitted.

The plate material separation device 1 is arranged near one side of the plate material support device 5 so as to attract and lift the vicinity of one end edge of the plate material S loaded on the plate material support device 5. More specifically, pillars 19 are erected at both side positions near one side of the plate material support device 5, and at the upper ends of both pillars 19, a horizontal column located at the upper part of the plate material support device 5 Both ends of the beam member 21 are supported. In other words, the entire structure is gate-shaped.

Vertical guide members 23 are provided on the mutually opposing inner surfaces of the pillars 19 on both sides, and an elevating member 25 is guided and supported on each guide member 23 so as to be movable up and down. Each lifting member 25
The lifter frame 27 integrally supports both ends of the lifter frame 27 located above the plate support device 5, and is configured to move up and down synchronously by the operation of an appropriate lifting device as described later. There is.

That is, a double structure drive sprocket 29 is provided near the upper end of the inner surface of each support column 19, and a driven sprocket 31 is rotatably provided below the drive sprocket 29. Upper and lower sprockets 2
A chain 33 is wound around each of the chains 9 and 31, and each chain 33 and each of the elevating members 25 are connected as appropriate. In order to rotate each driving sprocket 29 synchronously, a lifting motor 35 is mounted at an appropriate position on the beam member 21. The sprocket 37 provided on the output shaft of the lifting motor 35 and each drive sprocket 29 include:
An endless drive chain 39 is appropriately wound, and an idle sprocket 41 is rotatably provided near one of the drive sprockets 29. Therefore, by appropriately rotating the lifting motor 35, the lifter frame 2
It will be understood that 7 is raised and lowered.

As shown in FIGS. 1 and 3, an appropriate number of guide holders 45 are provided on the upper and lower surfaces of the lifter frame 27, respectively, for guiding and holding an appropriate number of lifting rods 43 in a vertically movable manner. In this embodiment, the lifting rod 43 is made of a pipe material, and a vacuum pad 47 is swingably attached to the lower end thereof as a suction attachment for suctioning the plate material S. Note that the suction attachment is not limited to vacuum pads, and it is also possible to use, for example, an electromagnet.

In this embodiment, each lifting rod 43 is made of pipe material, and its upper end is connected to an appropriate suction device and is connected to the lifter frame 27.
It is connected to a vacuum pipe 49 supported by a flexible hose 51. At the top of this lifting rod 43 is a weight 53 that acts as a stopper.
is screwed on so that its position can be adjusted. Therefore, by adjusting the position of the weight 53, the height position of the vacuum pad 47 when the weight 53 contacts the upper guide holder 45 can be made equal.

Each lifting rod 4 is connected to the lifter frame 27.
An appropriate number of fixing devices 55 are installed on the lifter frame 27 in order to fix the lifter 3 at any vertical position. More specifically, a backup plate 5 is provided between each lifting rod 43 and the lifter frame 27.
7 is provided, and an operating beam 5 is provided facing the backup plate 57 with each lifting rod 43 in between.
9 is provided. The operating beam 59 is provided so as to be able to reciprocate toward and away from the backup plate 57, and its appropriate position is set relative to the lifter frame 27 in order to operate the operating beam 59.
It is supported by a plurality of fixing cylinders 61 (see FIG. 2) as operating mountings mounted on the holder.

The operating beam 59 extends in the direction in which the lifting rods 43 are arranged (left-right direction in FIG. 2), and a back-up plate 57 for backing up each lifting rod 43 is provided at a position where the working beam 59 corresponds to each lifting rod 43. A pressing member 63 that can be pressed and fixed is provided.
This pressing member 63 is an integrally provided guide pin 6.
A spring 67 is elastically mounted between the pressing member 63 and the working beam 59 to bias the pressing member 63 in the direction of the lifting rod 43.

With the above configuration, each lifting rod 43 can be fixed and released by moving the actuating beam 59 toward and away from the backup plate 57 using the fixing cylinder 61. Therefore, when the lifter frame 27 is lowered and each vacuum part 47 comes into contact with the plate S with each lifting rod 43 released, each lifting rod 4
3 moves up and down relatively following the curves and uneven portions of the plate material S. Therefore, in this state, each lifting rod 43
By fixing the vacuum pad 47, the vacuum pad 47 will stick to the irregularities of the plate material S, etc.

In order to securely fix each lifting rod 43, it is desirable to form appropriate uneven portions such as serrations on each lifting rod 43 and the pressing member 63. Further, although it is possible to provide each operating beam for each lifting rod 43, it is preferable that one operating beam corresponds to a plurality of lifting rods 43.

Referring to FIGS. 1 and 2, the transfer device 7
serves to draw and transfer the plate material S, which has been adsorbed by each vacuum putt 47 provided in the plate material separation device 1 and has one edge lifted, from above the pallet 9 to a transfer station for sending it to the next process. It is something. The pedestal 69 of this transfer device 7 is constructed by appropriately combining shaped steel. On the side surface of this frame 69 facing the plate material support device 5, an appropriate number of stoppers 71 for positioning the pallet 9 fed onto the roller conveyor 11 of the plate material support device 5 and a stacked plate material S of the pallet 9 are provided. A general magnetic floater 73 is attached to magnetically separate one end edge. Further, a general two-sheet detector 75 is mounted on the side surface of the pedestal 69 to detect whether or not only one plate S has been separated by the plate separation device 1. Since the magnetic floater 73 and the two-piece detector 75 are well known, detailed explanation thereof will be omitted.

On the upper part of the pedestal 69 in the transfer device 7,
Support beams 77 are provided that pass between the columns 19 in the plate separation device 1 and extend above both sides of the plate support device 5 . A pair of inner rails 79 and outer rails 81 are laid in parallel on the support beams 77 on both sides.

More specifically, the support table 83 horizontally supports the plate material S separated by the plate material separation device 1, and both sides of the support table 83 are slidably supported on the inner rails 79 via a plurality of slide members 87. has been done. The vicinity of the center of the support table 83 is supported from below by a support roller 91 provided on the pedestal 69 via a bracket 89.

A plurality of free bearings 9 are provided on the upper surface of the support table 83 to support the plate material S in a movable manner.
3 is attached to the upper surface so as to be freely retractable, and a riding roller 95 is provided at the tip so that the plate S can be easily lifted onto the support table 83.
is rotatably provided.

In order to reciprocate the support table 83 along the inner rail 79, a sprocket 97 is rotatably provided on the pedestal 69 at a distance along the inner rail 79.
An endless chain 99 extending around the support table 83 is connected as appropriate. The sprocket 97 is appropriately connected to a table operating motor 101 mounted on the pedestal 69. Further, the pedestal 69 is provided with control switches 103, 105, and 107 such as limit switches for controlling the backward end, intermediate stop position, and forward end of the support table 83. Each of the above control switches 103, 10
5, 107 is a table operating motor 10 when operated by the chain 99 or a dog (not shown) provided on the support table 83.
This functions to control the operation of 1.

The pull-in clamp device 85 moves the plate material S separated by the plate material separation device 1 onto the support table 8.
3. It has the effect of pulling it upward. This retraction clamp device 85 is constructed by mounting a plurality of work clamps 113 on a horizontal moving beam 111 whose both ends are supported reciprocally on the outer rail 81 via a slide member 109. More specifically, the moving beam 111 is located above the upper surface of the support table 83 and is movable relative to the support table 83. The work clamp 113 is provided with upper and lower clamp jaws for clamping the edge portion of the plate material S, and since it is a general type, a detailed explanation thereof will be omitted.

In order to reciprocate the movable beam 111 along the outer rail 81, sprockets 115 are provided on the pedestal 69 at a distance in the direction along the outer rail 81, and an endless sprocket is wound around the sprocket 115. The chain 117 and the moving beam 111 are appropriately connected. Further, one sprocket 115 is suitably interlocked and connected to a retracting motor 119 mounted on the pedestal 69 (parallel to the operating motor 101 on the table, not shown). This retracting motor 119 can be controlled and driven as appropriate, either individually or synchronously with the table operating motor 101.

In the above configuration, when the pallet 9 on which the plate materials S are stacked is placed on the roller conveyor 11 by a forklift or the like, and is transferred toward the pedestal 69 of the transfer device 7 and comes into contact with the stopper 71,
The pallet 9 and the plate material S are positioned. The pallet 9 positioned as described above is pushed up by the lifter device 13, and the uppermost plate S
When the lifter device 13 reaches a predetermined height position, the operation of the lifter device 13 is stopped. The edge portions of the plate materials S near the top stacked on the pallet 9 are separated into upper and lower parts by the action of the magnetic floater 73.

When the plate material S is pushed up to a predetermined height position as described above, the fixation of each lifting rod 43 in the plate material separation device 1 is released, and the plate material S is suspended vertically by the weight 53, its own weight, etc. the lifter frame 27 by driving the lifting motor 35.
When the lift rod 43 is lowered, the vacuum pad 47 provided at the lower end of each lifting rod 43 comes into contact with the upper surface of the uppermost plate S near the edge. At this time, if the plate material S has a curve or an uneven portion, each lifting rod 43 moves up and down relative to the uneven portion, etc., and follows the upper surface of the plate material S. That is, almost all the vacuum parts 47 come into contact with the upper surface of the plate material S without any force.

As described above, after each lifting rod 43 follows the upper edge of the plate material S, the fixing cylinder 61 in the fixing device 55 is actuated to fix each lifting rod 43 to the lifter frame 27, and the suction attachment is lowered. The plate material S is attracted by the plurality of vacuum parts 47 by operating simultaneously or with appropriate timing. Thereafter, the lifter frame 27 is raised by rotating the lifting motor 35 in the opposite direction to that described above. When the lifter frame 27 is appropriately raised and the plate material S that has been sucked and raised integrally rises to a position corresponding to the two-piece detector 75, the lifter frame 27 is temporarily stopped and the two-piece detector 75 Then, it is detected whether or not two plates S are sucked, and if two plates S are sucked, they are combined into one plate by an appropriate operation. Next, the lifter frame 27 is further raised, and when the plate material S being sucked reaches a height position corresponding to the work clamp 113 in the transfer device 7, the lifter frame 27 stops raising.

After the lifter frame 27 stops rising, each lifting rod 43 is released from being fixed by the fixing device 55, and the weight 53 of each lifting rod 43 is attached to the upper guide holder 45.
The end edge of the plate material S becomes horizontal. When the edge of the plate material S is in a horizontal state in this way, the table actuating motor 101 is activated to advance the support table 83 until the control switch 105 for the intermediate stop position is activated, and the plate material S is almost The plate material S can be easily clamped by the work clamp 113 by keeping it horizontal. After that, the retracting motor 119 is activated to move the moving beam 1.
11 in the direction of the plate material S, and the moving beam 111
The edge portion of the plate material S is clamped by a work clamp 113 provided at. After clamping, the operation of the suction device is stopped and the suction of the plate material S by the vacuum pad 47 is released.

After the edge of the plate S is clamped by the work clamp 113, the table operating motor 10
1 and moves the support table 83 to the left in FIG.
It will be placed on 3. At this time, due to the action of the riding roller 95, the plate material S is not damaged. The entire plate S is placed on the support table 83 when the support table 83 is moved forward most and the control switch 107 is activated to stop it. After that, the table operating motor 1
01 and the retracting operation motor 119 are simultaneously driven to rotate in opposite directions and integrally moved to the original position, the plate material S is pulled into the transfer station for the next process. The plate material S drawn into the transfer station is transferred to the next process by an appropriate transfer means.

[Effects of the Invention] As can be understood from the above description of the embodiments, the present invention has a lifter frame 27 that is movably disposed above the mounting table 9 on which the stacked plate materials S are placed. A plurality of lifting rods 43 equipped with suction attachments 47 at their lower ends that can freely suction the plate material S.
The actuating beam 59, which is supported so as to be relatively vertically movable and extends in the direction in which each of the lifting rods 43 is arranged, presses and fixes each lifting rod 43 against the lifter frame 27 in a direction in which it is released. An actuating device 61 for moving the working beam 59 is provided, and each lifting rod 43 is provided at a position corresponding to each lifting rod 43 of the working beam 59.
A pressing member 63 is provided for pressing and fixing the lifter frame 27 to the lifter frame 27.

As is clear from the above configuration, in the present invention, the lifter frame 27 that supports a plurality of lifting rods 43 having suction attachments 47 at the lower end so as to be relatively movable up and down, An actuating beam 59 extending in the arrangement direction is provided, and an actuating device 61 for actuating the actuating beam 59.
is provided. Each lifting rod 43 is located at a position where the operating beam 59 corresponds to each lifting rod 43.
A pressing member 63 is provided for pressing and fixing the lifter frame 27 to the lifter frame 27.

Therefore, according to the present invention, when the lifter frame 27 is lowered and the plate material S on the mounting table 9 is to be suctioned by the plurality of suction attachments 47,
By keeping each lifting rod 43 fixed by the pressing member 63 in an open state, each lifting rod 43 can be adjusted to the lifter frame 27 in accordance with the unevenness of the plate material S.
It rises relatively to the surface and follows the unevenness of the plate material S.

When the actuating beam 59 is actuated by the actuating device 61, each lifting rod 4 is moved by each pressing member 63.
3 is fixed to the lifter frame 27 at the same time. That is, since the plurality of lifting rods 43 are simultaneously fixed and released by the operation of the operating beam 59, the structure for fixing and releasing becomes simpler.

Moreover, each lifting rod 43 is not directly pressed and fixed by the operating beam 59 extending in the direction in which the plurality of lifting rods 43 are arranged, but each lifting rod 43 is pressed and fixed by a pressing member 63 provided on the operating beam 59. Because of this configuration, even if there is a manufacturing error in the diameter of each lifting rod 43, for example, each lifting rod 43 can be reliably pressed and fixed at the same time.
