Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material conveying magazine and a method of vertically placing a plate material using the same, and more particularly to a plate material conveying magazine having a simple structure and easy handling and a plate material using the same. Vertical mounting method.

[0002]

2. Description of the Related Art Conventionally, cement-based board materials such as siding materials have been used as outer wall panels for prefabricated houses and the like. As a method of transporting the cement-based plate material such as the siding material, as described in Japanese Patent Laid-Open No. 3-264305, a semi-hardened cement-based plate material is laid on a tray plate in a large number and placed in a magazine rack. Hold and invert the magazine rack 90 degrees by the reversing device to hold the cement board side by side in a vertical posture, and put the magazine rack in the 90 degree inversion into the autoclave to cure and harden the cement board. A method of carrying is disclosed. The reason for curing and curing the semi-hardened cement board in the vertical position is that when the cement board is in the horizontal state, excess water that has leached out is left on the cement board and is discharged to the outside. Although not carried out, the surplus water flows down in the vertical position, so that the curing time by the autoclave can be shortened.

[0003]

However, in this method, when a large number of cement-based plate materials stacked on the tray plate are put in and held in the magazine rack, the pressing member provided in the magazine rack is used as the spring member. Insert the cement board in the state of pulling up against it, and when the insertion is completed, release the pushing force of the pressing member and elastically press the cement board loaded on the tray board by the spring force of the spring material. The handling was complicated because of this. Further, when the cement-based board material in the semi-hardened state is cured and cured, the spring material and the pressing member are thermally deformed, and the operation is not smoothly performed, which may cause a problem in handling. Further, since a pressing mechanism is required, there is a problem that it is complicated and inefficient in space.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a plate material conveying magazine which has a simple structure and is easy to handle, and a plate material vertical mounting method using the same. .

[0005]

A method according to the above-mentioned object.
The plate material conveying magazine described is a tubular support frame having a substantially square cross section having a gap into which each roller of the roller conveyor enters at least on one side surface, and is fixed to the tubular support frame, and is slightly inclined to the side where the rollers enter. And a plate material placing member having an upper end of the roller having a gap capable of projecting from the inner surface thereof, and fixed to the cylindrical support frame, and arranged orthogonal to one side end portion of the plate material placing member. And a plate supporting member.

A plate material carrying magazine according to a second aspect is the plate material carrying magazine according to the first aspect, wherein the inclination angle of the plate material placing member is 3 to 7 °. A method for vertically placing plates according to claim 3 is a method for vertically placing a plurality of horizontally stacked plates using the plate transport magazine according to claim 1 or 2, wherein the tubular support is provided. A frame, the plate material mounting member is mounted on a roller conveyor at a position in the lower portion, a step of carrying in the plurality of horizontally stacked plate materials on the plate material mounting member of the plate material transport magazine, A step of detecting that the plate material has been carried into the plate material transfer magazine, rotating the plate material transfer magazine by 90 °, and placing the end portion of the plate material on the plate material support member in a slightly inclined state.

According to a fourth aspect of the present invention, there is provided a method for vertically placing a plate material,
In the method according to claim 3, the plate material carrying magazine is rotated by 90 ° by a turning arm having an opening angle of 90 ° arranged at an intermediate position of each roller of the roller conveyor. According to a fifth aspect of the present invention, in the method of vertically placing the plate material according to the third or fourth aspect, the plurality of horizontally stacked plate materials are placed on a pallet. Claim 6
In the method for vertically placing the plate material described in the above, in the method according to any one of claims 3 to 5, the plurality of horizontally stacked plate materials or pallets are pressed against the plate material support member.

[0008]

In the method for vertically placing a plate material using the plate material transfer magazine according to claims 1 and 2 and the plate material transfer magazines according to claims 3 to 6, the tubular support frame of the plate material transfer magazine is provided on at least one side surface. There is a gap where each roller of the roller conveyor enters, and the plate material placing member that is arranged slightly inclined to the side where the roller enters and has a gap where the upper end of the roller can protrude from the inner surface is below the upper end of the roller. At a certain position, a plurality of horizontally stacked plate materials are loaded onto the plate material mounting member of the plate material transport magazine.
Next, when it is detected that the plate material has been loaded into the plate material transfer magazine and the plate material transfer magazine is rotated by 90 °, the plate material is fixed to the tubular support frame and is disposed orthogonal to one end of the plate material mounting member. The end portions of the plurality of plate members are in contact with each other on the support member and are placed in a slightly inclined state. Since the tubular support frame has a substantially square cross section, it is easy to handle.

Particularly, in the plate material carrying magazine according to the second aspect, the plate material mounting member has an inclination angle of 3 to 7 °.
If the inclination angle is 3 ° or less, the handling of the plurality of vertically placed plate materials is difficult due to lack of stability. on the other hand,
When the inclination angle is large, the inclination angle between the tubular support frame and the plate material mounting member and the inclination angle between the tubular support frame and the plate material supporting member are large, which is inefficient in space. Practically, the inclination angle is preferably 7 ° or less.

In the method of vertically placing a plate material according to a fourth aspect, the plate material conveying magazine is rotated by 90 ° by a turning arm having an opening angle of 90 ° arranged at an intermediate position of each roller of the roller conveyor. Therefore, the structure is simple and transport problems can be reduced. In the vertical placing method of the plate material according to the fifth aspect, since the plurality of horizontally stacked plate materials are placed on the pallet, stable handling can be performed regardless of the shape and strength of the plate material. In the vertical placing method of the plate material according to the sixth aspect, since the plurality of horizontally stacked plate materials or pallets are pressed against the plate material supporting member, the plate materials do not move while the plate materials are rotating.

As shown in FIGS. 3 and 8 and 9, the pressing device 15 includes a pressing cylinder 40 provided on a mounting seat 39 via a bracket 38 mounted on a base 33 of the roller conveyor 11, and a pressing cylinder 40. It is composed of a pressing member 41 attached to the tip of the. By pushing the rod of the pressing cylinder 40 forward, the pressing material 41 is applied to one end surface of the pallet 14, and the plurality of laterally stacked cement-based board materials 10 on the pallet 14 mounted on the board material mounting member 29 are mounted. The plate material conveying magazine 12 is pushed into the plate material supporting member 30 side. The pressing devices 15 are provided at two positions on both ends of the pallet 14 in the longitudinal direction and outside the turning arm 18.

The trolley 16 conveys a plate material conveying magazine 12 containing the cement-based plate material 10 which is placed in a substantially vertical state by the turning device 13 to a curing place, and as shown in FIG. 2, it travels above the building. The loading crane 17 is used to mount the plate material transport magazines 12 (four in this embodiment).

As shown in FIGS. 1 and 2, the loading crane 17 travels on the upper part of the building to transfer an empty plate material carrying magazine 12 which has been completely cured to a turning device 13 or to be driven by the turning device 13. This is for loading the plate material conveying magazine 12 in which the cemented plate material 10 in the vertical state is stored on the carriage 16.

Next, a method of vertically placing a plate material according to an embodiment of the present invention will be described. Note that the overall operation will be described with reference to FIGS. 1 and 2, and the details of the turning of the plate material transport magazine 12 will be described with reference to FIGS. 7 to 9. The empty plate material transport magazine 12 (FIG. 7A) on the conveyor 42 is transferred by the loading crane 17 onto the turning arm 18 of the turning device 13 (FIG. 7B). At this time, the closing member 27 is placed on the turning arm 18 substantially horizontally. At this time, the rod 37 of the hydraulic cylinder 36 of the turning device 13 is extended. With the plate material carrying magazine 12 placed on the two turning arms 18 of the turning device 13,
Pallet 14 with horizontally placed cement board 10
By the roller conveyor 11, the plate material transport magazine 12
The roller 11 a can be inserted to the inner frame space portion 44 of the plate material transfer magazine 12 so that the roller 11 a can be transferred onto the plate material mounting member 29. (As shown in FIG. 4, there are three closing members 27 on the side where the roller 11a is inserted, two plate member mounting members 29 and plate member supporting members 30, a lateral member 21,
A space is formed by 22 and. )

Next, the rod 37 of the hydraulic cylinder 36
With the retracting arm 18 slightly retracted, the turning arm 18 is rotated about the synchronous shaft 35 in the clockwise direction by about 3 °, and the closing member 27 is tilted by 3 ° with respect to the horizontal direction (in this state, the plate material transport magazine 12). The upper surface of the plate material mounting member 29 is below the upper end of the roller 11a of the roller conveyor 11), and a plurality of cement-based plate materials 10 horizontally stacked on the pallet 14 at a loading place (not shown)
Is fed into the empty plate material carrying magazine 12 (FIG. 8 (C)). At this time, the roller conveyor 11 is stopped by a pallet position detector (not shown).

Further, the rod 37 of the hydraulic cylinder 36
Is retracted a little, and the turning arm 18 is further rotated clockwise by 2 °, so that the closing member 27 is moved about 5 degrees with respect to the horizontal direction.
Tilt (in this state, the upper surface of the plate material placing member 29 of the plate material carrying magazine 12 is the same as or above the upper end of the roller 11a of the roller conveyor 11), and the cement board 10 in the plate material carrying magazine 12 is leveled. The state is set (FIG. 8D). Next, the rod of the pressing cylinder 40 of the pressing device 15 is extended, the pressing material 41 is applied to one end surface of the pallet 14, and a plurality of horizontally stacked cements on the pallet 14 mounted on the plate material mounting member 29 are placed. The plate material 10 is used as the plate material support member 3 of the plate material transportation magazine 12.
Push it so that it abuts 0 (FIG. 9 (E)).

Next, after the rod of the pressing cylinder 40 is contracted to retract the pressing member 41, the rod 37 of the hydraulic cylinder 36 is largely retracted, and the turning arm 18 is rotated.
Is rotated clockwise by 85 ° so that the closing member 27 is in a substantially vertical direction (FIG. 9 (F)). As a result, the cement-based plate material 10 in the horizontal (horizontal) state is rotated by 85 ° together with the plate material transport magazine 12 to be in a substantially vertical state (inclined by 5 ° with respect to the vertical direction). At this time, since the cement-based plate material 10 is in contact with the plate-material support member 30, the cement-based plate material 10 does not move in the plate-material transfer magazine 12 even when the plate-material transfer magazine 12 is rotated. in this way,
After the plate material transport magazine 12 has been rotated by 90 ° in total, the cement-based plate material 10 always has a constant inclination (5 ° with respect to the vertical direction, and this inclination causes no problem in the process).
Since it is held, it can be handled in a substantially vertically stacked state without falling.

Next, the plate material carrying magazine 12 on the turning arm 18 is lifted by the loading crane 17 to lift the cart 1
Place on top of 6. The dolly 16 on which a predetermined number of plate material transport magazines 12 are mounted is transported to a curing place, and the cement material plate material 10 is taken out from the plate material transport magazine 12 that has finished curing and is transported to the conveyor 42 by the loading crane 17.

As described above, the rotation of the plate material transport magazine 12 by the turning device 13 and the carriage 1 by the loading crane 17
6 is transferred to the cylindrical support frame 4 of the plate material transport magazine 12
3 can be performed using the outer frame portion, while the loading and unloading of the cement-based plate material 10 into the plate material transport magazine 12 are
This can be performed using the inner frame space portion 44 of the plate material transport magazine 12 (which is composed of the plate material mounting member 29, the plate material supporting member 30, and the closing members 25 and 28). Therefore, the handling of the plate material carrying magazine 12 can be performed regardless of the inclination of the cement-based plate material 10 in the plate material carrying magazine 12.

In this embodiment, the inclination of the cement board 10 is set to 5 ° with respect to the vertical direction, but it is practically 0 to 20.
And preferably 3 to 7 °. If it is 7 ° or more, the volumetric efficiency of the cement-based plate material with respect to the inner frame space portion of the plate-material conveying magazine is deteriorated, while if it is 3 ° or less, the cement-based plate material may collapse due to vibration during transportation. Further, in the figure, the cement-based plate material is stored in the plate material transport magazine in a substantially full state, but regardless of the number of sheets, it can be handled in a vertically stacked state without falling.

In this embodiment, since the semi-hardened cement board material is conveyed, a pallet is used. However, if there is no problem in strength of the board material during conveyance, the pallet may be omitted. At this time, when the pressing device is used, the required number of plate materials to be pressed is determined in consideration of the contact area of the pressing material, the strength of the plate material, and the like. Further, the pressing device does not necessarily have to be provided, and may be provided as needed.
