BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a magnetic material using a magnetic chain.

[0002]

2. Description of the Related Art An apparatus for transporting magnetic material comprising a combination of a magnet rail and a belt conveyor is known. However, in the known magnetic material conveying device, the conveyor belt is slackened, and a gap is generated between the magnet rail and the belt conveyor. As a result, the magnetic material is not sufficiently adsorbed. The disadvantage is that the position of the magnetic material is shifted. Further, in the case where the transport chain itself is constituted by permanent magnets to attract the magnetic material, the magnetic sheet is directly obstructed to the magnetic material sheet while the transport chain is running in order to release the magnetic material sheet from the transport chain. Mechanical force by the
No. 28), when a transport roller made of a permanent magnet is added to the transport chain, the magnetic sheet collides with a stopper during travel of the transport chain, and the magnetic sheet is released from the transport chain by mechanical force. (Japanese Unexamined Patent Publication No.
However, there is a drawback that a large impact force acts on the transport chain at the point where the magnetic sheet is forcibly peeled off during the action of the magnetic force, resulting in a large fluctuation in tension on the transport chain. .

[0003]

The problem to be solved by the present invention is that in a transfer device for a magnetic material applied to a destacking device or a piling device, a slack occurs in a transfer chain and a gap is formed between the magnet rail and the transfer chain. It is an object of the present invention to devise a magnetic material transporting apparatus that does not cause the magnetic material to be displaced on the transport chain during transport.

[0004]

The object of the present invention is attained by the features set forth in claim 1 of the utility model registration.

The present invention will be described based on an embodiment shown in the drawings.

1, 2, 3, and 4 show a case where the apparatus for transporting a magnetic material according to the present invention is applied to a sheet destacking apparatus. The destacking device comprises a lifting device 1 which piles the blank sheet material 2 and a magnet separator 3, and the magnet separator 3 acts on the uppermost area of the sheet pile until the suction force between the blank materials 2 becomes weaker. Help to pull apart. A sheet lift device 4 for reciprocating the piston by pneumatic drive above the piled blank material 2 is arranged so as to vertically move a piston rod having a suction head for sucking sheets one by one at a lower end. Has been established. The suction head is formed so as to perform vacuum suction. Another magnetic material chain 8 to be described below can be further provided on the blank material 2 having a large width with an interval in the depth direction from the plane of FIG. In that case, the seat lift device 4 is disposed between the two magnetic material chains 8 and the magnetic material chain 8
In the case where there is only one, it is arranged outside the traveling range of the magnetic material chain 8 so as not to interfere with the magnetic material chain 8, and is fixed to a stand (not shown). Lifting device 1 is blank material 2
Rises by the thickness of the blank material 2 each time one sheet is destacked by the sheet lift device 4, and the topmost height position of the piled blank material 2 always acts as it is.

The seat lift device 4 is provided above the lift device 1.
The magnet rail 5 and the endless magnetic chain 8 are disposed so as to cross the magnetic chain 8.
Is wound around the sprockets 6 and 7 in the range of both turning portions. Another chain 9 is wound around the sprocket 6 and the sprocket of the drive motor 10,
As a result, the rotation of the drive motor 10 is transmitted to the sprocket 6, whereby the magnetic chain 8 can run in the direction of arrow A. A normal magnetic roller chain or silent chain is used as the magnetic material chain 8, and in this case, is the suction surface for the blank material 2 a narrow side surface of the chain link [FIGS. 3 and 4 (a)]. ,
A flat chain [FIG. 4] in which a normal chain link is bent at a right angle and extended to adsorb the blank material 2 on a flat wide surface.
(B)] or a chain according to the shape and weight of the blank material 2 to be conveyed, such as a top plate chain (not shown), and whether the blank material has an irregular shape whose center of gravity is significantly separated from the center of its planar shape. The links can be variously shaped, or variously shaped adapters can be attached to the chain links. As shown in FIGS. 3 and 4A, the magnetic material chain 8 is
4 is guided while being attracted to the guide rail 11 in such a manner as to roll on the ridge-shaped guide rail 11 of the magnet rail 5 and sandwich the ridge- shaped portion of the guide rail from both sides with a chain link, or FIG. ), The chain roller 14 of the magnetic material chain 8 is guided by the guide rail 13.
The guide rail 13 is guided while being sucked by the guide rail 13 while rolling on the guide rail 13 while being fitted into the concave groove. The magnetic chain 8 is attracted to the magnet rail 5 and thus to the guide rail 11 or 13 by the magnet rail 5.
Of the blank material 2 by the action of the permanent magnetic field of the magnetic material chain 8 and the guide rail 11 or 1
3 is achieved by the action of the induced magnetic field of the magnetic chain 8 by the permanent magnetic field of the magnet rail 5 via the magnet rail 5. In the magnet rail 5 shown in FIG. 1, the blank 2 conveyed by the magnetic material chain 8 in the direction of the arrow A is separated from the magnet rail 5 within a range passing through the right end of the magnet rail 5 (region deviating from the magnet rail 5). As the distance increases, the induced magnetic field of the magnetic chain 8 is rapidly reduced, and the blank 2 is released from the magnetic chain 8 and dropped. FIGS. 5, 6 and 7 show the case where the magnetic material conveying device according to the present invention is applied to a sheet pile device. The sheet piler serves for destacking or unloading blank sheet material 2 from another sheet lifter or processing station, transported by a magnetic chain 8 and piled onto the lifter 1. The sheet pile device includes the lift device 1 and a pusher device 15 located above the lift device 1. Although the separator 3 is not required, a common device with the destack device is used, and only the pusher device 15 is connected to the sheet lift device 4. In some cases, the separator 3 is used after replacement. A pusher device 15 for reciprocating the piston by pneumatic drive is a lower end of a piston rod that moves up and down, and pushes the blank material 2 being sucked by the magnet rail 5 and being conveyed onto the lift device 2 so that the blank material 2 It will be piled one by one. At this time, the magnetic force for attracting the blank 2 is applied by the induced magnetic field of the magnetic chain 8 due to the permanent magnetic field of the magnet rail 5 and is smaller than the magnetic force due to the permanent magnetic field. During the travel, the pusher device 15 can be easily removed from the magnetic material chain 8 in the range of the magnet rail 5.

In the area where the pusher device 15 is provided, the magnet rail 5 is crossed with the pusher device 15.
An endless magnetic chain 8 is provided, and the magnetic chain 8 is wound around the sprockets 6 and 7 in both turning ranges. Another chain 9 is wound around the sprocket 7, and the chain 9 is wound around a sprocket of the drive motor 10 at another turning point. As a result, the drive of the drive motor 10 causes the magnetic material chain 8 to move in the direction indicated by the arrow B.
You will be traveling in the direction. Another magnetic material chain 8 can be provided for the wide blank material 2 at a distance from the plane of FIG. 1 in the depth direction. In that case, the pusher device 15 is disposed between the two magnetic material chains 8, and when there is only one magnetic material chain 8, the pusher device 15 is arranged so as not to interfere with the magnetic material chain 8.
And is fixed to a gantry (not shown).

When the blank material 2 reaches the area of the magnet rail 5 by sucking and transporting the blank material 2 by the magnetic material chain 8, the blank material material 2 is pushed down by the sheet pusher device 15. Will be piled up. Since the lift device 1 descends by the thickness of the blank material 2 every time one sheet is piled,
The height position of the uppermost blank 2 of the sheet pile is always unchanged.

The apparatus for transporting magnetic material according to the present invention can be used for transporting various types of blank material, whether it is flat, corrugated, can, dish-shaped, irregular or isotropic as long as it is a magnetic material. Can be done.

[0011]

According to the present invention, in the magnetic material conveying apparatus according to the present invention applied to the destacking device and the piling device, the gap due to the slack of the magnetic material chain is formed between the magnet rail and the magnetic material chain. Can occur,
The magnetic material chain is loosened and the magnetic material is not sufficiently adsorbed.The position of the magnetic material does not shift with respect to the magnetic material chain during transportation. The blank material can be accurately lowered to the position. Since the position of the blank material does not shift with respect to the magnetic material chain during transportation, the blank material is not damaged during transportation. In the region outside the magnet rail, the magnetic chain is not magnetized, so that the induction magnetic field of the magnetic chain is not formed by the permanent magnetic field of the magnet rail, so that the attraction of the magnetic material sheet to the magnetic chain is cut off. Therefore, the magnetic material sheet that has been sucked and conveyed by the magnetic material chain up to that point is
The magnetic sheet is released from the magnetic chain and falls without any mechanical force being applied to the magnetic sheet. As a result, fluctuations in the tension of the transport chain that occur during traveling of the transport chain are minimized.

Since the blank is directly sucked by the magnetic material chain, the chain does not meander even with a deformed blank. Great cost performance. Very easy to maintain. The magnitude of the magnetic force is determined by the magnet rail. In addition to being applied to destacking and piling devices, even if it is inclined, raised, curved, the blank material is below or above the magnetic chain, The present invention can be applied to various types of conveyance paths, even if the conveyance is reversed and the shape is twisted.
