To provide a panel transport device that can separate panels one by one and efficiently perform panel laying work.

[Disclosure of the invention]

The panel carrying device of the present invention includes a column having a plurality of claw engaging portions lined up in the vertical direction and whose lower end serves as a panel holding portion, and an ascending and descending body and a descending body fitted to the column so as to be able to move up and down, respectively. and a check pawl provided on the ascending/descending body and the descending body to engage with the pawl engaging portion of the support column to prevent the ascending/descending body and the descending body from descending; a pair of panels that are connected to each other so as to be rotatable in an opening/closing direction, extend substantially parallel to each other with their lower portions closed, and have a panel holder, and the panel holder holds stacked panels arranged between them. a pair of arm support levers each having both ends rotatably connected to the lowering and lowering body and both clamping arms, an opening/closing operation device for opening and closing the pair of clamping arms, and an opening/closing operation device attached to the clamping arm. The suspension rope engaging portion 14 is provided with a sling engaging portion 14.

According to the configuration of the present invention, each time the clamping arm is opened or closed by the opening/closing operation device, the clamping arm moves upward by one pitch of the pawl engaging portion with respect to the column. In other words, the lifting body to which the gripping arm is attached and the lowering lifting body to which the gripping arm is connected by the arm support lever are prevented from moving downward with respect to the column by the check claws, so the opening and closing of the gripping arm is prevented. Due to the expansion and contraction of the distance between the ascending and descending body and the descending body, the rising and descending body and the descending body move upward with respect to the column.

In this way, each time the clamping arm assembly rises relative to the column, and the column holds down the panel at its lower end, by opening and closing the clamping arm, the bottom panel is separated, and the remaining panels are separated. It will be held by the holding arm again after being shifted downward by one step. In this way, the panels can be easily separated one by one from the ones on the lower tier, so that the work of disposing the panels can be carried out efficiently.

As shown in FIG. 4(C), the outer surface of the ascending/descending body 4 is provided with a loading display 15 and a touch display 14 for aligning the direction of the claw operating handle 6a. The loading display 15 and the touching display 14 can be indicated by the words "loading" and "laying" or by a colored part, etc. When the claw operation handle 6a is aligned with the touching display 14, it is reversed. The stop pawl 6 has a sloped end facing upward as shown in FIG. 2, and the check pawl 7 has a similar structure to the check pawl 6 and is attached to the lowering/lowering body 5, and has a pawl operating lever 72.

The opening/closing operation device 12 will be explained. As shown in FIG. 2, an L-shaped bar 27 is rotatably attached to the ascending/descending body connecting rod 18, and an elongated hole 28 formed in a horizontal piece of the L-shaped bar 27
A lowering/lowering body connecting rod 19 is inserted through the lowering/lowering body connecting rod 19 . L-shaped bar 2
An opening/closing lever insertion tube 29 is formed at the tip of the horizontal piece 7, and the lower end of a round bar-shaped opening/closing lever 30 is inserted into and removably into the opening/closing lever insertion tube 29.

The safety device 31 (FIG. 1) will be explained. A second L-shaped lever 32 is attached to the ascending/descending body connecting rod 18 located near the rear strut/arm assembly 17 in the figure, and between the second L-shaped lever 32 and the tip of the horizontal piece of the above-mentioned lever 27. A horizontal bar 33 is joined to. Two safety levers 34 are rotatably attached to the horizontal bar 33, and a notch 34a on the lower surface of the tip of the safety lever 34 engages with the clamping arm connecting rod 20. The safety device 31 prevents the panel 10 from falling due to the unexpected opening of the clamps 7-1)A and 1IB.

The opening/closing and stepping movements of operation clamping arms 1)A and 1)B are
This will be explained based on the diagram and FIG. Figure 2 is panel 1
0 is held by clamping arms 1)A and 1)B,
The non-return pawl 6.7 is arranged so that the sloped end thereof faces upward.

That is, the claw operating levers 6a and 7a are set to the touching side. In this state, when the opening/closing lever 30 is rotated in the direction indicated by the arrow in FIG. 2, the L-shaped bar 27 is rotated in the direction indicated by the arrow B using the ascending/descending body connecting rod 18 as a fulcrum. At this time, the elongated hole 2B of the L-shaped bar 27 is engaged with the lower elevating body connecting rod 19, and as the L-shaped bar 27 rotates, the elongated hole 2B of the elongated hole 28 It will move relatively to . The distance from the ascending/descending body connecting rod 18 to the long hole 28 is longer at the left end position of the elongated hole 28, so as the L-shaped bar 27 rotates, the ascending/descending body connecting rod 18 and the descending body connecting rod 18 are connected. The distance between the rod 19 becomes longer. At this time, the lowering/lowering body 5 is prevented from moving downward by the non-return claw 7 engaging with the claw engaging portion l of the support post 3, and the lower end of the support post 3 is in contact with the top of the panel lO. , the ascending/descending body 4 ascends along the support column 3 as shown by arrow C. The check pawl 6 is easily removed upward from the pawl engaging portion 1. When the ascending/descending body 4 rises, the clamping arms IIA, II
Since B is connected to the lowering and lowering body 5 by the arm support lever 12, it opens and rotates as shown by the arrow, and moves as shown by the arrow E.
rise like. The arm support lever 12 rotates in the direction of arrow F. When the opening/closing lever 3o is rotated until the non-return pawl 6 engages with the pawl engaging portion 1 one pitch above and the rotation is stopped, the ascending/descending body 4 is held at that position, and the clamping lever LIA
, IIB are held open. This state is shown in Figure 3 (
A) is shown by a chain line, and FIG. 3(B) is shown by a solid line.

When the opening/closing lever 30 in FIG. 2 is rotated from this open state in the direction opposite to the arrow A, the elongated hole 28 and the lower elevating body connecting rod 19 are connected to each other as the L-shaped bar 27 rotates, contrary to the above. As a result of this engagement, the ascending/descending body connecting rod 18 and the descending ascending/descending body connecting rod 19 tend to approach each other.

However, since the ascending/descending body 4 cannot be moved downward due to the engagement of the non-return claw 6, the descending/descending body 5 rises as shown by the chain line in FIG. As the lowering and lowering body 5 rises, the holding arms 1)A and 1)B close.

In this way, the opening/closing lever 30 allows the clamping arm lIA,
When IIB is opened and closed, the clamping arm 1)A.

1) B can be moved upward by one pitch of the claw engaging portion 1 of the support column 3, and the lowermost panel IO can be separated. Therefore, the panel 10 can be installed easily.

Next, the operations from loading to laying the panel 10 will be explained according to FIGS. 4(A) to 4(N).

As shown in FIGS. 4(A) and 4(B), the opening/closing lever 30 is rotated in the downward direction to open the clamping arms IIA and IIB, and as shown in FIG. 4(C), the claw operating levers 6a and 7a are Align with loading display 15. In this state, as shown in FIG. 4(D), the entire panel transport device is lifted up by a crane via the hanging rope 35 engaged with the hanging rope engaging part 14, and the panel 1 is lifted up by a crane.
When the panel holding part 2 at the lower end of the column 3 hits the top surface of the panel 10, it is lowered slowly so as to sandwich the stack of 0.
While the column 3 remains stationary, the check claws 6 and 7 of the ascending/descending body 4 and the descending body 5 are freely disengaged from the claw engaging portion 1 of the column 3, and the clamping levers 1)A, IIB are lowered. Stacked panels 10
The number display 26 of the support 3 corresponding to the number of pieces (Fig. 4 (E)
) Stop the crane from lowering this panel transport device.

Then, turn the claw operation levers 6a, 6b toward the touch display 14 side.

- After this, as shown in Fig. 4 (F) (G), open/close lever 3
0 and close the clamping arms IIA and IIB. Thereby, the panel 10 is held by the panel holders 8.9 of the clamping arms 1)A, 1)B. After closing the clamping arms IIA and IIB, the safety lever 34 is rotated to engage the clamping arm connecting rod 20 (FIG. 4(H)), thereby completing the loading operation.

When laying the ground, place it in place 36 as shown in Figure 4 (!).
The panel carrying device is carried and lowered, and the hanging ropes 35 are sufficiently loosened. In this example, the touching place 36 is a beam that becomes a hallway of an apartment complex. After lowering the panel transport device in this way, remove the safety lever 34 (Fig. 4 (J)'), and then confirm that the claw operating levers 6a and 6b are on the touch display 14 side (Fig. 4 (J)'). (K)) After confirming the filtration, fully open the clamp arms 1)A and 1)B using the opening/closing lever 30, and then return them to their original closed states (Fig. 4 (L) and (M)).
.

Whether it is completely opened or not can be confirmed by the "clack" sound produced when the non-return pawl 6.7 engages with the pawl engaging portion 1. When the clamping arms IIA and IIB are opened and closed, the operation described above with reference to FIGS. 2 and 3 causes the bottom panel lO
are separated, and the holding arms 1)A and 1)B rise by one pitch of the claw engaging portion 1 of the support column 3 to hold the remaining panel 10. Thereafter, this panel transport device is lifted up by a crane and moved one panel next to panel 1O, as shown in Fig. 4 (K).
) to (M) until all the panels 10 are laid. When the laying is finished, return the claw operating levers 6a, 7a to the loading display 15 side. (Figure 4 (N)) This panel transport device Return to panel loading area.

FIGS. 5(A) to 5(D) show the process of laying the panels 10 in a row at the touching location 36 by the above-mentioned repeated operation.
As shown in FIG. 5(D), the last panel 10° does not have the joining protrusion 23 and cannot be held by the clamping arm IIA, so it is lowered into a two-layered state.

In the embodiment described above, the opening/closing operation device 13 is composed of an L-shaped bar 27 and an opening/closing lever 30, but the opening/closing operation device 13 includes a pair of clamping levers 1)A, IIB.
It may be of any type as long as it can be opened and closed, and other types of structures may be adopted.

〔Effect of the invention〕

In the panel carrying device of the present invention, each time the clamping arm is opened or closed by the opening/closing operation device, the clamping arm moves upward by one pitch of the pawl engaging portion relative to the column.

In other words, the lifting and lowering body to which the clamping arm is attached and the lowering and lowering unit to which the clamping arm is connected by the arm support lever are prevented from moving only downwards with respect to the column by the check claw. Due to the expansion and contraction of the distance between the ascending and descending body and the descending body as they open and close, the rising and descending body and the descending body move upward with respect to the column.

In this way, the clamping arm rises relative to the column each time it is opened and closed, and the column holds the panel at its lower end, so by opening and closing the clamping arm, the bottom panel is separated, and the remaining panels are held in place by the clamping arm. It will be held by the arm again after being shifted downward by one step. In this way, the panels can be easily separated one by one from the ones on the lower tier, which has the effect that the work of touching the panels can be carried out efficiently.
