However, according to the above construction, it is necessary to provide a chain sprocket for winding the endless roller chain on the driving side and the driven side, and the non-acting portion of the endless roller chain is Since a space to pass therethrough is required in parallel with the acting portion, there is a problem that a wasteful space is increased and the transport apparatus as a whole cannot be made compact.

Further, it is necessary to consider that a portion where the non-acting portion of the endless roller chain passes does not interfere with other members or a cover body is provided so as not to contact an operator. In terms of safety, there is a problem that it requires a lot of space and is bulky. Such a problem is not limited to the transporting device of the moving panel, and has always occurred when an endless roller chain is used to transport various loads.

The present invention has been made to solve these problems, and an object of the present invention is to provide a compact conveying device while using a roller chain.

[0007]

In order to achieve the above-mentioned object, a conveying device of the present invention comprises a roller chain which is movable by being inserted into a guide rail, and a storage box which communicates with one end of the guide rail. The guide rail is provided with an engaging means for engaging and disengaging a baggage, which is composed of a chain sprocket engaged with the roller chain and a driving means for rotating the chain sprocket forward and backward. It is characterized in that it can be moved back and forth along the guide groove.

A vertical axis 51 is rotatably and non-fallably supported by a support frame 50 suspended and fixed by a hanging rod from the ceiling via a bearing 58, and the lower surface side of the vertical axis 51 is the same as the guide rail 10. The rotating rail 52 having a cross-sectional shape is fixed. The end surface of the rotary rail 52 is formed in an arc shape in a plan view, and along the arc, the end surface of the main rail 4, one end surface of the end rail 13, both end surfaces of the guide rail 10, and the storage rails 11a and 11b. The starting end face is formed in an arc shape. A chain sprocket 53 is fixed to the upper part of the vertical axis 51, and an endless roller chain 57 is wound between the rotation motor 54 mounted on the support frame 50 and the drive chain sprocket 56 on the speed reduction mechanism 55 side.
When the rotation motor 54 is operated, the rotation rail 52 rotates 90 degrees in plan view and stops.

Next, a storage / conveyance device for moving the moving panel 5 forward and backward along the pair of storage rails 11a and 11b in the storage section 1 will be described.
It has substantially the same structure as the transfer device 9 provided on the guide rail 10 side, and a pair of guide rails 26 ′ on both sides of the storage rails 11 a and 11 b similar to those arranged on the side of the guide rail 10. , 26 'are arranged, and the roller chain 27' is arranged to move back and forth along the inside thereof.
A support block 34 'having the same structure as in FIGS. 5 and 6 is attached to the tip of the roller chain 27', and the second hook body 6 is attached to the support block 34 '.
Similarly, 0 is attached by the horizontal pin 35 so as to take the horizontal posture and the upward rotation posture.

The second hook bodies 60, 60 are provided with a downwardly extending locking groove 60a at the tip of the second hook body 60, 60 projecting upward on the support plate 30 below the pair of suspension supports 8, 8 in each moving panel 5. The two engaging members 61, 61 are engaged and disengaged. Therefore, in the plan view shown in FIG. 14, a direction (arrow C direction) in which the first locking member 31 can be removed from the first hook body 29 held in the horizontal state and the second hook held in the horizontal state in the same manner. Since the direction in which the second locking member 61 can be detached from the body 60 (the direction of arrow B) is orthogonal to each other, it moves along the main rail 4 to change the direction of the direction changing device 12, 1.
In the moving panel 5 stopped at two positions, the first hook member 29 is locked to the second locking member 61 by the second hook member 60 without rotating the first hook member 29 upward with respect to the first locking member 31. The moving panel 5 can be pulled and moved.

Roller chains 27 ', 27' arranged on the sides of the two storage rails 11a, 11b are drawn into and out of the storage boxes 62, 62 arranged at the ends of the guide rails 26 ', 26'. And each storage box 6
A chain sprocket (not shown) that engages with the roller chains 27 ′ and 27 ′ in 2, 62 includes one storage drive motor 63 (which can rotate forward and backward), a reduction mechanism (not shown), and a transmission shaft 64. It is driven to rotate (see FIG. 1), and the pair of roller chains 27 ', 27' and the second hook body 6 are connected.

Then, in order to unlock each second hook body 60 with respect to the second locking member 61, the guide rail 26 '.
An elevating guide rail 65, which is moved horizontally in a horizontal direction and has a length substantially equal to the length of the storage rail, is supported by an elevating guide shaft 66.
It is supported by a guide cylinder 67 which is fixed to the above and other parts so as to be vertically movable and cannot fall off. Further, the rack rod 68 provided so as to project upward from the elevating guide rail 65 is driven up and down by an elevating drive motor 69 and a pinion (not shown).

Therefore, when both the elevating guide rails 65, 65 are in the lowered position, the guide pins 36 'projecting laterally of the respective second hook bodies 60 do not contact the upper surface thereof, but both the second hooks. The bodies 60, 60 are retained in a state of being locked to the second locking members 61, 61 below the pair of suspension supports 8, 8.
On the other hand, when both the elevating guide rails 65, 65 are in the raised position, the guide pin 36 'is lifted and the tip side of the second hook body 60 is rotated upward to move the second locking member 61.
The lock with is released.

With these constructions, the guide rail 1 is attached to the moving panel 5 temporarily stopped at the stop device 14.
The roller chain 27 along 0 is advanced in the direction of arrow B to lock the first hook body 29 to the first locking member 31, and then after the releasing operation of the stop device 14, the roller chain 27 is moved in the direction of arrow A. When the pair of suspension supports 8 and 8 of the moving panel 5 come to the turning devices 12 and 12,

Lock 60.

Next, the pair of turning devices 12, 12 is set to 9
When it is turned 0 degrees, the suspension supports 8 and 8 are rotated to the rotary rails 52 and 5.
While riding on 2, swing horizontally by 90 degrees and store rail 11
It becomes possible to transfer to the starting end side of a and 11b. Therefore, the roller chains 27 ', 27' are retracted in the direction of arrow C and the second hook bodies 60, 60 move the moving panel 5 in the direction of arrow C at right angles to the storage rails 11a, 11b in plan view. be able to. At this time, as described above, the engagement between the first hook body 29 and the first engagement member 31 is naturally released.

Then, when the moving panel 5 is moved (retracted) in the direction of arrow C and stopped at a predetermined position to raise both the elevating guide rails 65, 65, each second hook body 60 causes the second hook member 60 to move. Since the lock is released with respect to 61, both the elevating guide rails 65, 65 are lowered after that, and the next moving panel 5 is drawn into both the storage rails 11a, 11b. 'To arrow D
Forward in the direction.

When the movable panel 5 suspended from the two storage rails 11a and 11b is carried out to the main rail 4 side, the operation is the reverse of the above, and the rotary rails 52 and 52 that are aligned with the two storage rails 11a and 11b. After the suspension supports 8, 8 are transferred to the rear, the first hook body 29 at the last retracted position is moved forward, and is locked by the first locking member 31, the rotary rails 52, 52
So as to be aligned with the guide rail 10,
12, and then the first hook body 29 is moved in the direction of arrow B by the operation of the hook drive motor 44. At this time, as described above, the second locking member 61 naturally comes off the second hook body 60. First hook body 29
When the guide pin 36 in step up on the inclined guide portion 32 in the vicinity of the entrance / exit 3, the locking of the first hook body 29 and the first locking member 31 is released, so that the moving panel 5 naturally stops. . From here, the operator manually moves the moving panel 5 along the main rail 4 to a predetermined partition. When the moving panel 5 passes through a seated switch position (not shown), the moving body 18 of the stop device 14 moves forward, and the succeeding moving panel 5 is restricted from leaving so as not to approach the moving panel 5 at the advanced position. .

FIG. 15 shows another embodiment of the engagement / disengagement relationship between the first hook member and the first locking member and the second locking member relationship with respect to the second hook member. The second locking member 73 is a round bar-shaped member or the like protruding upward from the upper end of the moving panel 5, and the first hook body 71 and the second hook body 7 are provided.

The present invention can be applied not only to transporting the moving panel of the above embodiment, but also to transport other loads. For example, the guide rail can be arranged horizontally, vertically inclined, or vertically curved if it is a type in which the luggage is hung and supported by a hook body as an engaging means. Furthermore, if the hook body does not receive a downward load and the luggage is pushed and pulled by the side of the guide rail, a guide groove is formed on one side of the guide rail and the hook body is guided along the guide groove. Can also be made movable.

[0030]

As described above, the transport device of the present invention has a roller chain that is movable by being inserted into a guide rail, and the roller chain in a storage box that communicates with one end of the guide rail. A chain sprocket engaged with the roller sprocket and drive means for rotating the chain sprocket forward and reverse, and engaging means for engaging and disengaging the luggage at the tip of the roller chain is provided in a guide groove formed in the guide rail. It is configured so that it can be reciprocally moved along.

According to this structure, the roller chain which is fed out from the storage box by the chain sprocket in accordance with the normal rotation of the driving means is inserted into the guide rail, and the engaging means is attached to the tip of the roller chain. The luggage can be pushed out and conveyed. Conversely, when the drive means is rotated in the reverse direction, the roller chain in the guide rail is drawn so as to be stored in the storage box, and the luggage can be drawn in and conveyed by the engaging means at the tip of the roller chain. it can.

Therefore, since the roller chain is present only at the position where it is inserted into the guide rail, the guide rail plays the two roles of the guide portion of the roller chain and the cover body at the same time. Further, unlike the conventional endless roller chain, a passage (space) for passing the non-acting part is not required, and a chain sprocket on the driven side is also unnecessary. Therefore, there is an effect that the conveying device can be made extremely compact.
