Description

The present invention relates to a plate material adsorbing device used for adsorbing a plate material having a ferromagnetic material at least partially when it is moved, separated, or fixed, and a plate material transport device configured by using the plate material adsorption device. In particular, the present invention relates to a ferromagnetic material carrying tool and a conveying device useful when conveying a ferromagnetic material formed in a thin plate shape.
Such a transport tool can be very useful for a system (transport device) for moving a plate-like ferromagnetic material such as an iron plate.

  In FIG. 5, the typical perspective view of the conventional board | plate material adsorption | suction instrument 200 is illustrated. The plate material adsorbing device 200 is manufactured as a ferromagnetic material transporting tool useful for transporting a plate-shaped ferromagnetic material, and the permanent magnet 20 is parallel to the bottom surface 20a and the opposite side thereof. It is formed in a columnar shape having a bottom surface 20b. The height direction of the column in the columnar solid shape coincides with the x-axis direction of the drawing. That is, the illustrated length h is the height of this columnar shape.

  In this plate material adsorbing device 200, four permanent magnets 20 are used. In each permanent magnet 20, n-poles are arranged on the bottom surface 20a whose normal direction coincides with the negative direction of the x-axis, and the normal line. The s pole is disposed on the bottom surface 20b whose direction coincides with the positive direction of the x-axis. As these permanent magnets, an Alnico cast magnet, a ferrite sintered magnet, a rare earth sintered magnet, or the like is used. These permanent magnets 20 are bonded with an adhesive such that the bottom surfaces 20a and 20b face each other.

  FIG. 6 is an explanatory diagram for explaining the operation of the conventional plate material adsorbing device 200. Description of magnetic field lines in the half space in the drawing is omitted. FIG. 6 is a schematic side view of the plate material adsorbing device 200 of FIG. 5, but in the past, in the conventional manner, in the x-axis direction, that is, in the height direction of each permanent magnet 20, it is practically one long piece. Magnets are formed, and the magnetic poles are arranged at the left and right ends. When the plate material adsorbing device 200 having such a structure is manufactured, as shown in FIG. 6, the magnetic field lines are arranged so as to greatly wrap around from the leftmost n pole to the rightmost s pole. The magnetic force of the plate material adsorbing device 200 is adjusted by adjusting the magnetic force of each permanent magnet or by optimizing the number of permanent magnets to be used. When adjusting the magnetic force of each permanent magnet, its size, material, etc. may be adjusted appropriately.

  Such a conventional plate material adsorbing device 200 is used when adsorbing and transporting a metal plate such as a plate-shaped iron plate. In particular, when a plurality of plate materials are stacked and loaded, and only one uppermost plate material is to be adsorbed, the plate material so that the normal direction of the plate material coincides with the z-axis direction of the drawing. An adsorption device 200 is used. According to this arrangement relationship, the amount of magnetic flux passing through the second plate material from the top can be suppressed relatively less than other arrangement relationships, so this method can be used when only the uppermost plate material is to be adsorbed. (Placement relationship) is adopted.

  However, for example, when the thickness of a plate made of a ferromagnetic material such as steel is 1 mm or less, only the uppermost one of the stacked plates is stacked using a conventional plate material adsorbing device. It may be difficult to adsorb. In such a case, as a countermeasure, a method of weakening the magnetic force of the plate material adsorption device can be considered, but if the magnetic force of the plate material adsorption device is weakened, it becomes difficult to stably and reliably adsorb the uppermost one plate material. Become. In addition, a method of increasing the number of plate adsorption devices with weak magnetic force and adsorbing only the uppermost one using a conventional plate adsorption device can be considered, but an increase in the number of plate adsorption devices used, In many cases, the form and configuration of the equipment are restricted due to an increase in the number of attachments of the plate material adsorbing device. Depending on the thickness of the plate material to be handled, a derivation problem occurs in terms of equipment change and equipment cost.

In order to solve such a problem, conventionally, for example, a floater or the like has been used in order to lift the uppermost plate member of the plate members stacked in piles. FIG. 7 illustrates the usage of the conventional floater 90. Reference numerals C1, C2, and C3 indicate iron plates having a thickness of about 0.5 mm, and due to the strong magnetic force of the floater 90, the right end portions C1a and C2a of the iron plates C1 and C2 are both temporary. Is magnetized in the s pole. For this reason, the right end C1a and the right end C2a are repelled by the magnetic force, and as a result, the iron plate C1 is lifted upward. Further, sometimes, in order to ensure this lifting, an auxiliary measure is taken between the iron plate C1 and the iron plate C2, such as sending air from the surroundings using a blower.
However, even when such a floater or blower is used, the costs associated with these instruments and devices are not negligible.

  Further, a plate material adsorbing device that adsorbs a plate material by sucking air is generally used. However, such a device assumes various requirements regarding the sealing property of the plate material, such as that the surface of the plate material is flat or smooth to some extent, or that the plate material is not provided with holes, etc. Such an apparatus is not necessarily appropriate when handling a general metal plate or the like that should allow for the optionality in forming a hole or an uneven shape, and its application range is limited. In addition, since such an apparatus uses an atmospheric pressure difference, there are not a few cases where derivative problems occur in terms of equipment cost, apparatus operating efficiency, apparatus controllability, and the like.

The present invention has been made to solve the above-described problems, and its purpose is to stably and surely adsorb only the uppermost sheet when a large number of thin plates are stacked and stacked. It is to realize a plate material adsorption device that can be used.
A further object of the present invention is to realize a plate material adsorbing device excellent in application range, equipment cost, controllability, operation efficiency, and the like.
Furthermore, a further object of the present invention is to realize a plate material adsorbing device that is less prone to chipping and is less likely to be damaged.

Moreover, the further objective of this invention is implement | achieving the board | plate material conveyance apparatus which fully harnessed the advantage of the above board | plate adsorption devices.
However, it is sufficient that the above-mentioned individual objects are achieved individually by at least one of the individual means of the present invention, and the individual inventions of the present application simultaneously solve all the above-mentioned problems. It does not necessarily guarantee that there is a means that can be solved.

In order to solve the above problems, the following means are effective.
That is, according to the first means of the present invention, when a plate material having a ferromagnetic material at least partially is moved, separated, or fixed, m pieces (m ≧ m) are used in the plate material adsorption device used for magnetically adsorbing the plate material. 2), the m permanent magnets are fixed to each other with the same kind of magnetic poles facing each other, thereby forming m-1 joints, and the joint surfaces of at least one joint This is to adsorb the plate material by bringing a part of the periphery of the metal plate or a part of the side wall of the joined body of at least one joint part closer to or in contact with the plate material.

  However, the shape of the joint may be considered two-dimensionally or three-dimensionally. In other words, the above-described joined body means a space occupied by the adhesive when, for example, an adhesive that joins the permanent magnets has a thickness that cannot be ignored. In addition, it is assumed that the above joined body can exist as such a gap region between magnets regardless of whether or not an occupying substance such as an adhesive is present in such a gap region.

  According to a second means of the present invention, in the first means described above, the permanent magnet is substantially plate-shaped in which one side of two substantially parallel bottom surfaces is N-pole and the other side is S-pole. In this case, a plate material adsorbing surface for adsorbing the plate material is formed by collecting and aligning a part of each side wall of the m permanent magnets on the same surface.

  Moreover, the 3rd means of this invention is forming the joining part of m-1 places by joining the same kind magnetic poles with an adhesive agent in said 1st or 2nd means.

  According to a fourth means of the present invention, in any one of the first to third means, the permanent magnet is composed of a rubber magnet or a bond magnet.

According to a fifth means of the present invention, there is provided a plate material transporting device for transporting a plate material having a ferromagnetic material at least in part, wherein the plate material adsorbing instrument constituted by any one of the first to fourth means is used. It is to provide at least one or more.
By the above means of the present invention, the above-mentioned problem can be effectively or rationally solved.

The effects obtained by the above-described means of the present invention are as follows.
That is, according to the first means of the present invention, the permanent magnets are fixed with the same kind of magnetic poles facing each other, so that the magnetic poles disappear locally when the different magnetic poles are joined together. There is no. That is, unlike the conventional configuration of FIG. 5, there is no fact that a single elongated magnet is formed, and the magnetic poles of the individual permanent magnets are locally dispersed even after the plate material adsorbing device is configured. Be placed. For this reason, the distance between the n pole and the s pole closest to each other is maintained at the shortest without changing from the distance before the junction. As a result, most of the magnetic lines of force that run from the n-pole side to the s-pole side are concentrated in the vicinity of the plate material adsorption device, and as shown in FIG. Therefore, according to the first means of the present invention, since the region having a high magnetic flux density can be concentrated in the vicinity of the plate material adsorption device, a plate material (ferromagnetic material) such as an iron plate having a thickness of 1 mm or less is stabilized. Can be reliably adsorbed, and at the same time, it is possible to easily avoid adsorbing the second plate located below.
That is, according to the first means of the present invention, even when a large number of thin plate materials are stacked and stacked, a plate material adsorbing device that can stably and surely adsorb only the uppermost one is easily manufactured. be able to.

  The permanent magnet to be used is a substantially plate-shaped permanent magnet in which one of two substantially parallel bottom surfaces is an N pole and the other one is an S pole, and a part of each side wall of each of the permanent magnets is the same surface. A configuration in which a plate material adsorbing surface for adsorbing a plate material is formed by gathering and aligning them on top is also found in, for example, the conventional plate material adsorbing device 200 of FIG. In the case of FIG. 5, the above-mentioned same plane means the xy plane or a plane parallel to the xy plane. If such a structure is followed, the structure of a board | plate material adsorption | suction instrument can be simplified, Therefore The manufacturing cost and productivity of a board | plate material adsorption | suction instrument can be made favorable.

  However, in the conventional plate material adsorbing device 200 of FIG. 5, it is not possible to obtain the operation and effect of the first means of the present invention. The second means of the present invention has been conceived to achieve both of these actions and effects. Therefore, according to the second means of the present invention, the action of the first means of the present invention described above. -While obtaining an effect, the structure of a board | plate material adsorption | suction instrument can be simplified, and the manufacturing cost and productivity of a board | plate material adsorption | suction instrument can be made favorable.

  In these plate material adsorption | suction apparatuses of this invention, the method of joining permanent magnets may be arbitrary. The string may be wound and fixed many times, or may be fixed using a gummed tape or a vinyl tape. However, if these means are used, there is a risk that the dimensional error of the plate material adsorbing device and the variation for each product will increase. In addition, the dimensions of the plate material adsorbing device may change over time, and the production time tends to be long.

  However, according to the third means of the present invention, since the same kind of magnetic poles are joined together with an adhesive, such a fear is small. In particular, it is desirable to use a strong instantaneous adhesive as the adhesive. According to the third means of the present invention as described above, the dimensional error of the plate material adsorbing device and the variation of each product may occur, the size of the plate material adsorbing device may change over time, or There is less risk of lengthening the time.

Moreover, according to the 4th means of this invention, since said permanent magnet is comprised from a rubber magnet or a bond magnet, a board | plate material adsorption | suction instrument does not break or chip. Moreover, since it is easy to form at least the surface of a rubber magnet or a bond magnet softly, there is no risk of scratching the plate material to be handled.
Further, these materials are flexible, have excellent shape flexibility, have high dimensional accuracy, and can be formed thin, so that high productivity can be ensured in addition to the above effects. In particular, when a plate material having a thickness of 1 mm or less is adsorbed, it is easy to adjust the strength of the magnetic force moderately.

  Further, specific actions and effects of the fifth means of the present invention will be illustrated in detail in Example 2 described later. According to the fifth means of the present invention, even when a large number of thin plates are stacked and stacked, it is easy to manufacture a plate material transporting device that can stably adsorb and transport only the uppermost one. can do.

Hereinafter, the present invention will be described based on specific examples.
However, the embodiments of the present invention are not limited to the following examples.

  FIG. 1 is a schematic perspective view of a plate material adsorbing device 100 according to the first embodiment. In this plate material adsorbing device 100, a total of eight permanent magnets 10 having similar shapes are alternately arranged in the opposite direction and periodically arranged in the x-axis direction. In other words, for any of the eight permanent magnets 10 in total, the bottom surface whose normal line points to the negative direction in the x-axis direction is called the bottom surface 10a, and the normal line points to the positive direction in the x-axis direction. The bottom surface is called the bottom surface 10b. At this time, the bottom surfaces 10a of the odd-numbered permanent magnets 10 have n poles in order from the front left side, and the bottom surfaces 10a of the even-numbered permanent magnets 10 have s poles in order from the left side.

  The adjacent permanent magnets 10 are opposed to each other with the same magnetic poles and joined with a strong instantaneous adhesive. For example, the first permanent magnet 10 from the left side on the near side and the second permanent magnet 10 from the left side on the near side are bonded to each other with the s poles facing each other and fixed with a strong instantaneous adhesive.

  Each permanent magnet 10 is composed of a high-performance rubber magnet (anisotropic flexible magnet). That is, this rubber magnet is manufactured by kneading and rolling a ferrite magnet powder having a high characteristic with a relatively inexpensive material and a synthetic rubber or polymer resin for imparting appropriate elasticity. Thus, the crystal orientation of the ferrite magnet powder is mechanically oriented in one direction.

The characteristics of such a rubber magnet are summarized below.
(A) Magnetic properties are higher than sintered isotropic ferrite magnets.
(B) Easy post-processing such as punching, cutting, drilling and bending.
(C) The specific gravity can be manufactured lightly.
(D) High degree of freedom in dimension and shape.
(E) There is no worry about cracks and cracks like a sintered magnet.
(F) Since it is rich in elasticity, vibrations of the plate material can be reduced or damage to the plate material can be avoided during adsorption or transportation.

  In other words, in the plate material adsorbing device 100 described above, the permanent magnet 10 is a substantially plate-shaped permanent magnet in which one of two substantially parallel bottom surfaces has an N pole and the other surface has an S pole, and has eight permanent magnets. A plate material adsorbing surface for adsorbing a plate material is formed by collecting and aligning a part of each side wall of the magnet on the xy plane, and the configuration of the plate material adsorbing device 100 described above is the first to first of the present invention. It can be said that all four means are implemented at the same time.

  FIG. 2 is an explanatory diagram for explaining the operation of the plate material adsorbing device 100 according to the first embodiment. If the plate material adsorbing device is configured as described above, the permanent magnets are fixed to each other with the same type of magnetic poles facing each other, so that the magnetic poles disappear locally when the different types of magnetic poles are joined together. Does not happen. That is, unlike the conventional configuration of FIG. 5, there is no fact that a single magnet having a simple structure extending long is formed, and the magnetic poles of the individual permanent magnets remain locally even after the configuration of the plate material adsorption device. Distributed. For this reason, the distance between the n pole and the s pole that are closest to each other is maintained at the shortest without changing from that before the bonding. As a result, as shown in FIG. 2, most of the magnetic field lines running from the n-pole side to the s-pole side are concentrated in the vicinity of the plate material adsorbing device. Therefore, according to the present invention, since the region having a high magnetic flux density can be easily concentrated in the vicinity of the plate material adsorbing device, a plate material (ferromagnetic material) such as an iron plate having a thickness of 1 mm or less can be stably and reliably provided. At the same time, it is possible to easily avoid the adsorption of the second plate located below.

By configuring such a plate material adsorbing device 100, even when a large number of thin steel plates having a thickness of about 0.2 mm are stacked and laminated, the plate material (ferromagnetic material) can be stably and reliably adsorbed, It has been found that the adsorption of the second plate material located below can be avoided.
By adjusting or optimizing the following adjustment parameters, it is possible to manufacture an optimal plate material adsorbing device corresponding to the thickness of the plate material.
(A) Magnetic force and size of each permanent magnet (b) Arrangement period of each permanent magnet in the x-axis direction in FIG. 2 (c) Number of arrangement of permanent magnets By appropriately selecting the values of these adjustment parameters, the plate material Even when a large number of layers are stacked, it is possible to adjust so that only the uppermost plate is stably and reliably adsorbed.

  In FIG. 3, the usage example of the board | plate material adsorption device 100 in the present Example 2 is illustrated typically. This example is an example in which the plate material adsorbing device 100 of the first embodiment is used for the configuration of the conveyor 600. The distance between the left and right bottom surfaces of the feed roller R described in a substantially cylindrical shape (substantially columnar height H) is secured to the same extent as the width of the plate material to be sucked and transported. The substantially columnar height H of the roller R may be larger or smaller than the width of the plate material, but it is preferable that the plate material is interposed between at least two belts 60. The belt 60 may be made of metal, plastic, rubber, or cloth.

For example, when the belt 60 is formed of a metal chain, the feed roller R is preferably provided with, for example, a gear-like convex portion that fits into the concave portion (hole or groove) of the chain (belt 60). Alternatively, the feed roller R may be configured so that three gears are arranged in parallel at substantially equal intervals around a single rotation shaft (rod). The material and configuration of these belts and rollers may be selected appropriately or optimally according to the size, thickness, weight, etc. of the plate material to be adsorbed and transported.
For example, when the plate material is very heavy, it is of course desirable to configure the belt 60 with a metal chain. Since a rubber magnet or the like can be easily processed, forming the plate material adsorbing device 100 using a rubber magnet or the like is advantageous when assembled to a belt such as a chain. In this case as well, the plate material adsorbing device 100 may be assembled so as to be in direct contact with the plate material (metal plate to be conveyed).

Further, each belt 60 is provided with the plate material adsorbing device 100 of the first embodiment described above at an appropriate arrangement period. This interval does not necessarily have to be constant. A method of fixing the plate material adsorbing device 100 to the belt 60 may be arbitrary.
For example, when such a belt conveyor (conveyor 600) is manufactured, a plate made of a ferromagnetic material or the like can be adsorbed downward (or any one of the upper sides) and carried.

FIG. 4 is a schematic side view of the plate material transport apparatus 800 according to the third embodiment. The configuration of the second embodiment is applied to the plate material transport device 800. That is, also in FIG. 4, the belt 60 and the feed roller R having the same configuration as in FIG. 3 are used. For example, each belt 60 of the conveyor 600 is provided with the plate material adsorbing device 100 of Example 1 described above at an appropriate arrangement period. However, in FIG. 4, the description of the plate material adsorbing device 100 is omitted.
The vertical movable axis α of the feed roller R1 is vertically controlled by the take-in control arm 70. Since the horizontal movable shaft β for rotationally driving the feed roller R2 is supported and fixed so as to have some elasticity in the horizontal direction, the tension applied to the belt 60 according to the vertical reciprocation of the take-in control arm 70 is increased. It moves slightly in the horizontal direction so that the fluctuation range is minimized.

  Each of the other feed rollers R also drives each conveyor 600 to rotate. The raising / lowering mechanism 81 and the raising / lowering mechanism 82 are comprised with the hydraulic lift. On the left side of the lower surface of the conveyor 600 on the right side of FIG. 4, a single plate material C is adsorbed by an appropriate magnetic force by the plate material adsorption device 100. This plate material C is the last (lowermost) plate material loaded on the plate material supply stand 82a of FIG. 4, and the plate material C loaded second from the last (lowermost) is the main plate material C. It is adsorbed on the upper surface of the left conveyor 600 in FIG. 4 and conveyed to the left side.

  When the take-up control arm 70 is pushed downward, these plate materials C are pushed downward simultaneously by the lower movable central portion of the vertical movable shaft α, the feed roller R1, and the belt of the conveyor 600 (belt 60 in FIG. 3). , It is adsorbed by the lower central part of the conveyor 600 and taken in on a conveying line composed of two conveyors 600. However, when the plate material C stacked on the plate material supply table 82a is adsorbed to the lower central portion of the conveyor 600 as described above, the position of the plate material supply table 81a is slightly lower than the position shown in FIG. Was located at. Such position control is synchronously controlled among the take-in control arm 70, the lift mechanism 81, and the lift mechanism 82 so that the throughput (transport efficiency) of the transport line is kept substantially constant.

  That is, the elevating mechanism 81 and the elevating mechanism 82 continuously and stably supply a large number of plate materials C on the transport line composed of the two conveyors 600 by a so-called double buffering method. . In addition, since these two conveyors 600 both have a configuration conforming to the first embodiment and the second embodiment, the plate material stacked in a large number on each plate material supply base (81a, 82a). C can be reliably adsorbed one by one and taken into the transport line.

[Other variations]
The embodiment of the present invention is not limited to the above-described embodiment, and other modifications as exemplified below may be made. Even with such modifications and applications, the effects of the present invention can be obtained based on the functions of the present invention.

  For example, in the first embodiment (FIG. 1), a high-performance rubber magnet (anisotropic flexible magnet) is used for each permanent magnet 10, but the type of these permanent magnets 10 may be arbitrary. An anisotropic rare earth bonded magnet (an example: Nd—Fe—B material) may be used.

  In the second embodiment (FIG. 3), the conveyor 600 is configured by using three belts 60, but the number of belts to be used may be arbitrary. In the second embodiment, the plate material adsorbing devices 100 are arranged on the belt 60 in a row substantially periodically. However, these arrangement forms need to be arranged in a row or periodically. There is no.

  In the third embodiment (FIG. 4), the plate material transport device 800 is configured using two conveyors 600. However, the conveyor 600 on the left side in FIG. For this, a normal conveyor that does not have the plate material adsorbing device 100 may be adopted.

  In the third embodiment (FIG. 4), the conveyor 600 is pressed against the plate material C by the up and down movement of the take-in control arm 70, and the plate material C is taken into the conveyance line. The configuration of the apparatus to be taken in may be arbitrary, for example, may be prepared independently of the conveyor 600. For example, the patent publications of Japanese Patent No. 1978784 and Japanese Patent No. 1978785 have a system configuration in which a charging device having an air cylinder and a vacuum cup is prepared in a configuration independent of a predetermined conveyor and a metal plate is taken into a predetermined conveyance line. Although illustrated, in constructing such a charging device, the above-described plate material adsorbing device 100 or the like can be arranged in the position of each vacuum cup instead of using an air cylinder or a vacuum cup. In such an embodiment, the operation and effect of the present invention based on the means of the present invention can be obtained.

It can also be used when moving, separating or fixing a plate material having a ferromagnetic material at least partially.
Therefore, for example, when the material, thickness, weight, etc. are substantially constant, for example, when a large number of plates with different detailed specifications such as color are irregularly mixed and stacked, these plates are The plate material adsorbing apparatus of the present invention is also very useful because it can pick up the plate materials one by one from the top even when it is desired to configure a device that automatically classifies items.
