Transporting wheel rails with a large number of wheels (
A structure is provided in which the rollers are arranged in multiple upper and lower stages with the sliding direction inclined. According to this conventional structure, loads thrown into the upper part of the slope slide on wheels and are stopped by a stopper provided at the lower end, and loads that are thrown in sequentially are stopped by the previous loads and stored. will be done. The stored load is then taken out from the lower part of the slope as needed, and the removal trace is filled in by the sliding of the rear load.

Problems to be Solved by the Invention According to the conventional method as described above, the load is moved by sliding using the free rotation of the wheels, so the free rotation may not be carried out smoothly or there may be variations in the load. In some cases, the sliding cannot be performed reliably, resulting in poor reliability. Furthermore, in view of frictional resistance, for example, some pallets may not be usable depending on their material. For these problems, it is possible to set a sufficient angle of inclination, but if the angle of inclination is large, the sliding speed will be high and not constant, and when the stopper is stopped, the impact will be large, etc. stability becomes poor. In addition, the dead space on the slope will increase, resulting in inefficient storage.

A bolt 93 passed from below through a through hole 92 formed in
It can be freely connected to the nut 91 via the port I/hole 90.

As mentioned above, the conveyance device 12 consisting of a pair of conveyors 10.11 is arranged in a conveyor direction 1 in a group of six conveyors (a plurality of conveyors) in a predetermined arrangement, as shown in FIG. 10, for example.
3, multiple groups, in the example 8 groups A, B, C,
D, E, F, G, and H are arranged, and the transmission devices 50 can be freely connected and separated for each group A to H. That is, each group is provided with a supply/discharge hose 95 having cylinder devices 56 connected in series, and these supply/discharge hoses 95 are connected to a common air supply hose 98 from an air supply device 97 via a solenoid valve 96, respectively.・Can be shut off freely. 99 indicates a regulator, 100 indicates a silencer, each group A~
At the downstream end of each H, a photoelectronic switch 101, which is an example of a stock detector, is provided. Here, in two groups adjacent in the conveying direction 13, when the optoelectronic switch 101 of the upstream group is in the detection operation and the optoelectronic switch 101 in the downstream group is not in the detection operation, the transmission devices 50 of both groups are simultaneously in the connection operation ( The air supply hose 98 and the supply/discharge hose 95 are configured to communicate with each other. When the photoelectronic switches 101 in both groups are simultaneously in the detecting operation or in the non-detecting operation at the same time, the transmission devices 50 in both groups are configured to simultaneously perform the separating operation (cutting off the air supply hose 98 and the supply/discharge hose 95).

To this end, each solenoid valve 96 is connected to a respective control unit 10.
It is incorporated within 2. Further, only the most downstream group A is configured so that the transmission device 50 is separated and moved when the optoelectronic switch 101 is detected and moved.

The supply/discharge hose 95, the air supply hose 98, etc. are piped into the recess 20. 1 to 3 indicate stoppers.

In the above embodiment, each conveyor frame 14.80 includes a roller 31, a guide rail 35, a transmission device 50, an idling roller 78.88, etc., and also includes a recess 2.
A hose 95.98 is piped to the 0, and the shelving equipment will be installed on site. Each conveyor 10.degree. 11 is then attached during or after assembly of the shelf frame 1. This can be done by aligning the bolt hole 26.90 with the through hole 28.92, and then tightening the bolt 29.93 passed through the through hole 28.92 from below by engaging the nut 27.91. At that time, when the conveyance path 46 is long,
Each conveyor io, il is joined lengthwise. However, things like Cheno 41 are shared.

Next, the storage and transportation of the load 47 in the above embodiment will be explained.

4 and 5, the solenoid valve 96 is switched to connect the air supply hose 98 to the supply/discharge hose 95, and the expansion of the cylinder device 56 due to air pressure causes the support shaft 70 to swing upward, and the transmission roller 72 The state in which the rollers 31 are pressed against the corresponding rollers 31 from below is shown. At this time, the chino 41 is constantly being driven by the motor 45, and therefore the sprocket 71 engaged with the chino 41 is rotating around the support shaft 70. Further, the transmission roller 72 is in contact with the lower portion of the outer circumference of the roller 31, thereby forcing the group of rollers 31 to rotate. As a result, the pallet 48 on the conveyance path 46 is moved by the rollers 31 and idle rollers 7 of both conveyors 10 and 11.
8.88, and is conveyed on this conveyance path 46 while receiving a conveyance force due to the forced rotation of the roller group 31. At this time, the idle roller 78 that is not driven
．． 88f\ performs follow-up rotation.

The conveying device 12 consisting of a pair of conveyors 10 and 11 basically conveys the pallet 48 (load 47) as described above, but in reality, the photoelectronic switch 101
Conveyance control is performed based on whether the pallet 48 is detected or not detected. That is, when the transport path 46 is empty, the forklift truck 8 moves the group H at the upstream end.
When the pallet 48 is lowered, the optoelectronic switch 101 of group H operates, but the optoelectronic switch 1 of group G
Since 01 is not detected, the transmission device 50 is connected by the operation of the control unit 102 and the solenoid valve 96, and the rollers 31 of group H1G are forcibly rotated, thereby transporting the pallet 48 from group 14 to group G. do. When pallet 48 enters group G, this group
Since the optoelectronic switch 101 detects and operates but does not detect group F, the transmission devices 50 of groups G and F are connected and move to transport the pallet 48 from group G to group F. The pallets 48 thus conveyed sequentially to the downstream side come into contact with the stopper 103 and stop, and are stored in group A.

When this pallet 48 is detected by the opto-electronic switch 101, the transmission device 50 of group A is driven by the same amount. The second pallet 48 is conveyed in the same manner, and is stored in group B in contact with the pallet 48 to the group. At this time, group B is detected and moved, but since group A is also detected and moved, the transmission device 250 of group B is also driven by that amount. In such an operation, it is assumed that, for example, as shown in FIG. 7, pallets 48 are stored in all groups A to H, and all transmission devices 50 are driven in minutes. In this state, when the pallet 48 of group A is taken out by the forklift truck 8 as shown in FIG. Then, as shown in FIG. 9, the pallets 48 of group B are conveyed to group A. Then, since the optoelectronic switch 101 of group B becomes non-detected, the transmission devices 50 of groups B and C are connected, thereby transporting the pallet 48 of group C to group B as shown in FIG.

By repeating such actions, the pallets 48 can be sequentially fed.

For example, as shown in FIG. 11, by taking out the pallet 48 of group A while sequentially feeding the pallets 48 from group E to group D, sequential feeding can be performed at two locations in the direction of the conveyance path 46, and in the same way. 312i
It is possible to perform forwarding of more than one location.

In the above embodiment, the driven rollers 31 and the non-driven idle rollers 78 were arranged every other time.
Alternatively, when one conveyor 10 is all driven by rollers 31,
It is particularly suitable for the pallet 48 made of resin.

In the above embodiment, the conveying device 12 is a pair of left and right conveyors 10.
．． 11, and only one of the conveyors 10 is driven, but it is also possible to use long rollers and form the conveying device 12 with only the driven conveyor 10.

Effects of the Invention According to the present invention having the above configuration, the conveying device has rollers, a transmission device, etc. disposed within the conveyor frame, and can be installed and transported to the site in unit units with piping installed in the recessed portion. It can be assembled into a shelf frame. Therefore, assembly of the shelf equipment and repair of the conveyance device can be easily performed, and furthermore, control piping and the like can be done compactly at the production site. When in use, the transmission device is connected and moved to transmit the driving force of the drive body to the rollers, and by forcing the rollers to rotate, pallets (loads) can be conveyed. Conveyance of the pallet can be stopped by deactivating the rollers. At that time, by detecting the presence or absence of cargo in each group and controlling the connection and separation of the transmission device, pallets can be sent sequentially between groups, and the pallets can be stored densely from the group at the downstream end to the group at the upstream side. I can do it. In this way, the pallet can be forcibly moved, and reliable movement (progressive feeding) can always be performed regardless of load variations or the material of the pallet. Moreover, since the moving speed can be made constant, it is possible to carry out stable transportation, and furthermore, it is possible to arrange horizontally, eliminate the conventional dead space, and provide IIN equipment with good storage efficiency.
