Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for suspending and moving a plate material, and in particular, for suspending and moving a scrap plate which is scraped due to a flaw or the like in a thick plate before finish rolling. The present invention relates to a plate material suspending / moving device suitable as a device to be dropped into a bag or the like.

[0002]

Conventionally, in a thick plate manufacturing process, a plate piece that is scrap due to a flaw or the like in the thick plate before finish rolling is moved in a suspended state and dropped into a scrap bag. The work of putting in is done,
It can be suspended and moved while stably supporting such plate pieces,
Moreover, there is no device that can be easily removed by dropping it on the scrap bag.

That is, as a suspension moving device for thick plates,
There is a slab lifter that lifts up with the tip of the claw pressed against the side surface of the plate material, but this is for thick plate materials with a plate thickness of 80 mm or more, and is usually scraped.
With a 0 mm thick plate, it is not possible to suspend and move while stably supporting it. Further, according to the claw hacker in which the wire rope is attached to the upper end of the L-shaped metal fitting that receives the lower surface of the plate material, by engaging the metal fittings at a plurality of positions of the plate material, the thick plate to be scraped is stably supported. However, when removing the suspended plate, it is necessary to place a bar called a 10,000 bar underneath the plate and lift the plate from the bracket to remove the bracket. Is hard to come off from the plate.

Further, as a device capable of stably moving a thin plate in a suspended state, it has a plurality of pairs of L-shaped arms in the length direction of the plate member, which are engaged with the plate member from the respective widthwise outer sides, and are directed inward. There is a sheet lifter that receives the lower surface of the plate material by the claw portion (the upper surface is formed horizontally). However, also in this case, when all the L-shaped arms are moved outward in the width direction to remove the suspended plate member from the lower surface of the plate member, the plate member is placed on the upper surface of the claw portion. Since the shaped arm receives a relatively large load from the plate member, the plate member follows the movement of the L-shaped arm, and as a result, a force that causes the plate member to rotate in the plane is exerted. The plate material remains on the claws and becomes difficult to remove. Therefore, as described above, it is necessary to remove the L-shaped arm in a state where the plate member is floated from the L-shaped arm by using a bar or the like.

The present invention has been made by paying attention to the problems of the prior art as described above, and it is possible to suspend and move while stably supporting a plate material, and to claw from the plate material without using a bar material or the like. It is an object of the present invention to provide a suspension moving device that can be easily removed.

[0006]

In order to achieve the above object, the present invention provides an L-shaped arm having inwardly facing claw portions for receiving the lower surface of the plate member on each side in the width direction of the plate member, and the L-shaped arm. L-shaped arm supporting device for supporting the plate member so as to be movable back and forth from each side in the width direction, a pressing arm for pressing the plate member on each side in the width direction, and the pressing arm as the L-shaped arm. A holding arm support device that separately supports the plate member so as to be movable back and forth from each side in the width direction, and a hanging mechanism engagement that integrally engages the L-shaped arm support device and the holding arm support device with a hanging mechanism. A suspension moving device for a plate material is provided.

According to the plate material hoisting and moving device of the present invention, when the hoisting mechanism is engaged with the hoisting mechanism engaging portion to hoist and move the plate material, the L-shaped arm is advanced to the plate material and its claw portion is used. Since the lower surface of the plate member is received, the plate member is stably suspended and moved. At that time, if the plate member is pressed by the pressing arm, the suspending movement is performed more stably. Further, when the plate material is removed, the claw portion is removed from the lower surface of the plate material by retracting the L-shaped arm from the plate material while the plate material is being pressed by the pressing arms on each side in the width direction. Thereby, when the claw portion is removed, the pressing arm restrains the plate material from following the movement of the claw portion, so that the plate material is prevented from rotating in the plane,
The claw can be easily removed from the plate material. Then, if the pressing arm is subsequently removed from the plate material, the plate material easily drops.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a plate material suspending / moving device in this embodiment, FIG. 2 is a front view of an L-shaped arm viewed from the direction A in FIG. 1, and FIGS. It is a perspective view showing a state.

This suspension moving device has a long plate (suspension mechanism engaging portion) 1 arranged in the length direction of a plate S to be suspended and moved, and a hook suspension fixed to the center of the upper surface of the long plate 1. The metal fittings (suspension mechanism engaging portion) 11 and the width direction members 2 to 4 arranged below the long plate 1 with the length direction orthogonal to the long plate 1 and the width direction members 2 and 3. Two pairs of L-shaped arms 5 and 6 supported on the lower side so as to be movable along the length direction thereof.
And a pair of pressing members 7 supported on the lower side of the width direction member 4 so as to be movable along the length direction thereof.

In this embodiment, the widthwise members (L-shaped arm supporting devices) 2 and 3 for supporting the L-shaped arms 5 and 6 support the pressing member 7 at each end of the long plate 1 in the lengthwise direction. A width direction member (holding arm support device) 4 is arranged at the center of the long plate 1 in the length direction. Each of the width direction members 2 to 4 has a rail below which guides the L-shaped arms 5 and 6 or the upper end of the pressing member 7 along the length direction, and the L-shaped arms 5 and 6 or the pressing arm along the rail. The L-shaped arms 5 and 6 and the pressing member 7 are moved automatically by remote control. As a result, the L-shaped arms 5 and 6 and the pressing member 7 are independently supported by the long plate 1 so as to be movable back and forth with respect to the plate material S from each side in the width direction.

The L-shaped arms 5 and 6 have claws 51 and 61 at their lower ends that receive the lower surface of the plate S at the widthwise ends of the plate S, and the claws 51 and 61 are the widthwise members 2 and 3. The lower ends of the shafts 52 and 62 extending vertically downward from are bent at right angles, and the upper and lower surfaces thereof (shown by reference numerals 51a and 51b in FIG. 2) are formed as inclined surfaces. And each two L-shaped arms 5, 6
With the claw portions 51 and 61 opposed to each other in the width direction members 2,
The claws 51 and 61 are attached inwardly in the width direction of the plate material S by being attached to the plate member 3. Also, the claws 51, 6
The inclined surface of the upper surface 1 is provided to facilitate removal of the claw portions 51 and 61 from the lower surface of the plate material S.

The pressing member 7 is, for example, a plate material having a predetermined thickness in a gate shape (the lower portions are bifurcated pressing arms 7a and 7b).
It is formed by cutting out into a plate, and is arranged so that its plate surface extends vertically downward from the width direction member 4. Further, the lower end position of the pressing member 7 is lower than the upper end position L ₁ of the claw portions 51, 61 of the L-shaped arms 5, 6, so that the L-shaped arms 5, 6 are sandwiched from the side surface in the width direction. Plate material S
The surfaces of the pressing arms 7a and 7b are surely pressed against the respective side surfaces in the width direction of the.

Therefore, when the scrap thick plate piece is suspended, the crane in which the hook is hooked on the metal fitting 11 is operated, and the scrap thick plate piece (plate material S) is first moved to above the scrap thick plate piece. The L-shaped arms 5 and 6 of the L-shaped arms 5 and 6 are suspended and moved, and the distance between the L-shaped arms 5 and 6 and the pressing member 7 forming a pair by the width-direction members 2 to 4 is wider than the width of the plate material S. The crane is lowered to a position where the upper surfaces of the claw portions 51 and 61 are below the lower surface of the plate material S.

After that, the L-shaped arms 5 and 6 and the pressing member 7
By moving the plate inward in the width direction of the plate S,
As shown in FIG. 2, at each end in the length direction of the plate S, the plate S is placed on the claws 51 and 61 of the L-shaped arms 5 and 6, and the side faces in the width direction are formed by the shafts 52 and 62. At the central portion in the length direction of the plate material S, the side surfaces in the width direction of the plate material S are sandwiched and held by the pressing arms 7a and 7b of the pressing member 7. In this state, the crane is lifted and laterally moved to the upper position of the scrapback, and then lowered to the drop position set in consideration of equipment damage prevention and noise prevention.

Next, by moving only the L-shaped arms 5 and 6 toward the outer side in the width direction of the plate material S while keeping the pressing member 7 as it is, the plate material S is moved by the pressing arms 7a and 7b as shown in FIG. The claw portions 51 and 61 of the L-shaped arms 5 and 6 are removed from the lower surface of the plate material S in a state where each side surface in the width direction is pressed. At this time, since both side surfaces in the width direction of the plate material S are supported by the pressing arms 7a and 7b, the plate material S does not follow the movement of the claw portions 51 and 61 and does not rotate in the plane, and the claw portion 51 , 6
Since the upper surface 1 is an inclined surface, the claw portions 51 and 61 can be easily separated from the plate material S.

After the claws 51 and 61 are disengaged from the plate material S, the pressing member 7 is moved outward in the width direction of the plate material S to remove the pressing arms 7a and 7b from the plate material S, whereby the plate material S is removed. In the air at the drop position, the suspension is released from the suspension device and falls into the scrap bag. The plate material S
The movement of the pressing member 7 at the time of opening is detected by, for example, providing a load sensor (for example, an ON / OFF switch) on the L-shaped arms 5 and 6, and detecting that the plate material S is detached from the L-shaped arms 5 and 6 by the load sensor. If you do it immediately after being told,
This is preferable because the plate material S is reliably dropped.

As described above, in the hoisting and moving apparatus of this embodiment, both sides of the plate S facing in the width direction of the plate S at four points in the lengthwise direction (L-shaped arms 5 and 6 and the pressing arms 7a and 7b). Since the plate material S is suspended and moved while pressing the surface, the plate material S can be stably suspended and moved. Further, the suspended plate material S can be easily removed from the L-shaped arms 5 and 6 without using a bar material or the like.

Here, the force applied to the plate member when the claw portion of the L-shaped arm is detached from the plate member will be described with reference to FIGS. As shown in these figures, in order to remove the claw portion, when the claw portion is moved outward in the width direction of the plate material while the plate material is on the plate material S, the plate material S is obliquely sandwiched (one end in the length direction and the other. Forces F ₁ and F ₂ outwardly in the plate width direction are generated on the portions of the plate material on the L-shaped arms 5 and 6 arranged at the ends), whereby a force F ₃ (rotating the plate material S in the plane is generated. A clockwise force is generated in the case of FIG. 5, and a counterclockwise force is generated in the case of FIG. On the other hand, the pressing arms 7A and 7B adjacent to the L-shaped arms 5 and 6 have forces F ₄ and F ₅ that press the plate S inward as a reaction of the force of the plate S pressing the pressing arms 7A and 7B. Occurs. As a result, a force F ₆ opposite to the force F ₃ is generated on the plate material S, so that the plate material S is prevented from rotating in the plane.

Therefore, as in this embodiment, with respect to the L-shaped arms 5 and 6 arranged at the respective ends in the lengthwise direction on the respective sides in the widthwise direction of the plate material S, the L-shaped arms are arranged from the center position in the lengthwise direction. By disposing the pressing arm 7a on the No. 5 side and the pressing arm 7b on the L-shaped arm 6 side from the center position in the longitudinal direction, it is possible to prevent the plate material S from rotating both clockwise and counterclockwise. Also,
In the above-described embodiment, in order to stably suspend and move the plate material S, the L-shaped arms 5 and 6 are arranged on the end side in the length direction of the plate material S, and the holding arms 7a and 7b are arranged on the center side in the length direction. However, the L-shaped arms 5 and 6 do not necessarily have to be arranged outside the pressing arms 7a and 7b (in the length direction of the plate material). That is, as shown in FIGS. 5 and 6, the longer the distance from the rotation center of the plate S to the holding arms 7A, 7B, the holding arms 7A, 7B for obtaining the same rotation moment (force F ₆ ).
Since the rigidity of can be made smaller, it is necessary to dispose the pressing arm on the end side in the length direction of the plate material S for this purpose.
The pressing arm may be arranged outside the L-shaped arm.

Further, in the above embodiment, the widthwise sides of the plate S are pressed by pressing the surfaces of the pressing arms 7a and 7b against the lateral sides of the plate S in the widthwise direction. The present invention is not limited to this, and any material can be used as long as it can restrain the movement of the plate material S in the width direction. Further, in the above-described embodiment, the pair of L-shaped arms and the pressing arms are provided at positions facing each other in the width direction of the plate material, but these do not necessarily have to be arranged facing each other.

The number of the L-shaped arms and the holding arms to be installed is not limited to the number in this embodiment, and is set according to the length of the plate material to be suspended and moved, the rigidity of the L-shaped arms and the holding arms, and the like.

[0022]

As described above, according to the hoisting and moving device of the present invention, when the plate member is removed, the plate member is prevented from following the movement of the L-shaped arm and rotating in the plane, and Since the part is easily detached from the plate member, the suspended plate member can be easily removed from the L-shaped arm and dropped in the air without using a rod member or the like. As a result, the work of dropping the thick plate scraps into the scrap bag is efficiently performed.
