BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage conveyor apparatus utilizing a storage conveyor such as a gravity roller conveyor for temporarily storing loads.

[0002]

2. Description of the Related Art When constructing a large-scale temporary storage storage conveyor device, it is conceivable to construct a long-length storage conveyor, for example, a gravity roller conveyor, in a plurality of upper and lower stages in a plurality of rows. Can be In such a case, unless the inclination angle of the gravity roller conveyor is kept at the required upper limit, the load that slides downward due to gravity will have a long sliding distance. The impact at the time of colliding with the stopper at the end or the previously stopped load is increased, which causes inconvenience such as collapse of the load. However, if the inclination angle of the gravity roller conveyor is kept to a necessary minimum, there is a possibility that the load may unexpectedly stop due to contact with a side guide or the like in the middle of the gravity roller conveyor. When such a situation occurs, the situation may be such that the worker can easily approach the place and take appropriate measures such as moving the load stopped on the conveyor. desired.

On the other hand, when a large number of gravity roller conveyors are arranged in parallel in the horizontal direction, if the entirety is supported by a common support frame, the support frame itself becomes large, and its assembly accuracy and installation accuracy are increased. Even if assembly and installation can be performed with high accuracy, a wide support frame that supports the entire gravity roller conveyor due to local level change due to deterioration of the installed floor surface over time and subsidence. Local stress concentration may occur, which may lead to accidents such as breakage.

At the unloading end (inclination lower end) side, one collecting drive conveyor 8 is disposed for each unit, and a unloading driving conveyor 9 for merging and discharging the loads from the respective collective driving conveyors 8 is stored. It is arranged at right angles to the conveyor 3 and horizontally. The assembling drive conveyor 8 is capable of changing the angle in any direction up, down, left, and right with the unloading end side as a fulcrum,
By changing the angle, the carry-in end can be moved up and down three levels and horizontal three levels within one storage conveyor unit 1A or 1B.
Alternatively, it can be connected to the discharge end of the storage conveyor 3 in the row.

As shown in FIGS. 2 and 4, the supporting frames 4, which are provided upright at appropriate intervals in the longitudinal direction of the storage conveyor 3 independently for each of the storage conveyor units 1A and 1B, are arranged in the horizontal direction. Conveyor support members 10 are provided in upper and lower three stages. On each of the conveyor support members 10, three rows of storage conveyors 3 in the left-right horizontal direction are supported in parallel. Therefore, the height of the conveyor support member 10 changes little by little for each supporting frame 4 so that the storage conveyor 3 to be supported is inclined at a predetermined angle over the entire length. Also, as shown in FIGS. 1A and 4, the floor surface 11 on which the support frame 4 is erected is also provided so that the height of the support frame 4 that supports the inclined upper end side of the storage conveyor 3 is not unduly increased. The storage conveyor 3 is formed in a stepwise manner so as to be higher toward the upper end side of the slope.

As shown in FIGS. 2 to 4, the maintenance / inspection corridor 2 comprises a corridor main body 12 and a support member 13 for suspending the corridor main body 12 at appropriate intervals in the longitudinal direction.
A pair of right and left support members 13 are provided so as to rise vertically from both left and right sides of the corridor main body 12, and a hook portion 13a is formed at an upper end thereof. Note that the pair of left and right support members 13 may be separately fixed to the left and right sides of the corridor main body 12, or integrated with a horizontal member supporting the corridor main body 12, and the corridor main body 12 is mounted on this horizontal member. It may be fixed.

The maintenance and inspection corridor 2 is suspended at an appropriate height of the passage 5 between the two storage conveyor units 1A and 1B by using support members 13 which form a pair of right and left. That is, the hook portion 1 of the support member 13 is attached to the horizontal connecting member 14 in the length direction of the conveyor located on the side of the passage 5 of the supporting frame 4 in both storage conveyor units 1A and 1B.
The maintenance and inspection corridor 2 is suspended by hanging the 3a so as to be freely detachable.

Further, the corridor body 11 of the corridor 2 for maintenance and inspection
Is a storage conveyor 3 as shown in FIGS. 1A and 4.
Are divided into a long horizontal portion 15 along the length direction and a short inclined portion 16 connecting between the long horizontal portions 15, and each of the portions 15, 16 is provided with a support member 13. Of course, the support members 13 are disposed at both ends in the longitudinal direction of the portions 15 and 16, and especially for the horizontal portion 15 having a long overall length, the support members 13 are also provided at appropriate positions in the middle in the longitudinal direction. It is arranged.

[0014] As shown in FIG.
A stair (or ladder) 17 for raising and lowering the worker can be attached to at least one end in the length direction of, for example, the end on the side where the height from the floor decreases. In addition, the erection height of the maintenance and inspection corridor 2 is such that the storage conveyor 3 below the corridor 2 can perform maintenance and inspection from the floor 11 in the passage 5 and the storage conveyor 3 above the corridor 2. 3 is set so that maintenance and inspection can be performed from the corridor 2. Therefore, when the number of storage conveyors 3 is large and the height of the storage conveyor units 1A and 1B is higher, the maintenance and inspection corridor 2 may be constructed with two or more stages. Of course, it is not necessary to install the maintenance and inspection corridor 2 over the entire length of the passage 5 between the storage conveyor units 1A and 1B, and for example, an area where the maintenance and inspection of the storage conveyor 3 can be performed from the floor 11 or another mount. In this case, the maintenance inspection corridor 2 can be omitted.

Further, in the illustrated embodiment, each of the storage conveyor units 1A and 1B is constituted by three upper and lower storage conveyors 3 in three horizontal rows. However, the number of rows and columns of the storage conveyors 3 is not limited. 5 inner floors 1
1 and the corridor 2, the storage conveyor units 1 </ b> A and 1 </ b> B on both the left and right sides must be configured so that maintenance and inspection of all the storage conveyors 3 can be performed. Of course, if a maintenance inspection passage can be secured outside the left and right storage conveyor units 1A, 1B with the passage 5 interposed therebetween, the number of storage conveyors 3 in each storage conveyor unit 1A, 1B can be increased. Further, as shown in FIG.
A and 1B can be used as a unit, and a plurality of units can be arranged in parallel. In this case, it is possible to secure a passage between the storage conveyor units 1A and 1B adjacent to each other on the back side opposite to the passage 5 side, and to install the maintenance inspection corridor 2 in the passage.

As the storage conveyor 3, a gravity roller conveyor is generally used. When the total length is particularly long, for example, a fixed area on the carry-in end side is constituted by a drive conveyor, and the carried load is accelerated downward. It is also possible to configure so that it can be sent out.
