Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to shelving equipment employed for storing loads directly or via pallets and for taking them out when necessary.

BACKGROUND TECHNOLOGY Conventionally, this type of shelving equipment, as seen in Japanese Utility Model Publication No. 18750/1983, has been constructed by mounting a wheel rail having a large number of wheels on a shelf frame and tilting the conveying (sliding) direction of the wheel rail. A structure is provided in which they are arranged in multiple upper and lower stages. According to this conventional structure, the load thrown into the upper part of the slope slides on the wheel and is received by the stopper provided at the lower end, and the loads thrown in sequentially are caught by the previous load and stored. Become. 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 above-mentioned conventional method, 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 the impact will be large when it is caught by the stopper, making the load unstable. It becomes a bad thing. Additionally, the dead space on the slope will be expanded, resulting in inefficient storage.

The object of the present invention is to provide a transport device that can reliably move loads at a constant speed while keeping the transport direction horizontal, that can be easily assembled and repaired, and that can compactly organize control piping, etc. We are happy to provide you with shelving facilities for use.

As described above, the conveying device 12 consisting of the pair of conveyors 10 and 11 is arranged in a plurality of groups in the conveying direction 13, each group consisting of six conveyors (a plurality of conveyors) arranged in a predetermined manner, as shown in FIG. 10, for example. Then 8 groups A, B, C, D, E, F, G, H
are arranged, and a transmission device 5 is arranged for each group A to H.
0 can be freely connected and separated. That is, each group is provided with a supply/discharge hose 95 connected to the cylinder device 56 in series, and these supply/discharge hoses 95 are connected to each other in series.
Each of them can be freely connected to and disconnected from a common air supply hose 98 from an air supply device 97 via a solenoid valve 96. 99 indicates a regulator, and 100 indicates a silencer. At the downstream end of each group A to H, there is a photoelectronic switch 10, which is an example of a stock detector.
1 is provided. Here, in two groups adjacent in the conveying direction 13, when the photoelectronic switch 101 of the upstream group is in the detecting operation and the photoelectronic switch 101 in the downstream group is not detecting, the transmission devices 50 of both groups are simultaneously in the connecting operation ( The air supply hose 98 and the supply/discharge hose 95 are configured to communicate with each other. And photoelectronic switch 101 of both groups
When both groups are simultaneously detected or not detected simultaneously, the transmission devices 50 of both groups are configured to perform a separating operation (blocking the air supply hose 98 and the supply/discharge hose 95) at the same time. For this purpose, each solenoid valve 96 is integrated into a respective control unit 102. Also, only the most downstream group A has its photoelectronic switch 1.
01 is detected, the transmission device 50 is configured to separate and move. The supply/discharge hose 95, the air supply hose 98, etc. are piped into the recess 20. 103 indicates a stopper.

In the above embodiment, each conveyor frame 14,
The roller 31, guide rail 35, transmission device 50, idle rollers 78, 88, etc. are incorporated in the roller 80, and hoses 95, 98 are piped into the recess 20, and the roller 80 is transported to the installation site of the shelving equipment. Each conveyor 10, 11 is attached during or after assembly of the shelf frame 1. This can be done by aligning the bolt holes 26, 90 with the through holes 28, 92, and then tightening the bolts 29, 93 passed through the through holes 28, 92 from below by engaging the nuts 27, 91. At that time, transport route 4
When 6 is long, each conveyor 10, 11 is joined in the length direction. However, parts such as Chain 41 are shared.

Next, the storage and conveyance operations 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 chain 41 is constantly driven by the motor 45, and therefore the sprocket 71 engaged with the chain 41 is rotating around the support shaft 70. Further, the transmission roller 72 is connected to the roller 31
The group of rollers 31 is forcibly rotated by contacting the lower part of the outer periphery of the roller. As a result, the pallet 48 on the conveyance path 46 is supported between the rollers 31 of both conveyors 10 and 11 and the idling rollers 78 and 88, and receives the conveyance force caused by the forced rotation of the group of rollers 31. 46. At this time, the idle roller 7 that is not driven
The 8th and 88th groups perform follow-up rotation.

Conveying device 1 consisting of a pair of conveyors 10 and 11
2 is basically created from palette 4 as described above.
8 (load 47), but in reality, the transport is controlled based on whether the photoelectronic switch 101 detects or does not detect the pallet 48. That is, when the pallet 48 is unloaded onto group H at the upstream end with the conveyance path 46 empty, the photoelectronic switch 101 of group H operates to detect, but the photoelectronic switch 101 of group G does not detect. Due to the fact that
is forcibly rotated, thereby conveying the pallet 48 from group H to group G. When the pallet 48 enters group G, the photoelectronic switch 101 of this group G operates to detect, but since group F is not detected, the transmission devices 50 of groups G and F operate to detect the pallet 48.
connects and transports 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, stop, and are stored in group A. When this pallet 48 is detected by the photoelectronic switch 101, the transmission devices 50 of group A are separated and moved. The second pallet 48 is conveyed in the same manner, and is stored in group B by coming into contact with the pallets 48 of group A. At this time, group B is detected and moved, but since group A is also detected and moved, the transmission device 50 of group B is also separated and moved. In such an operation, for example, as shown in FIG. 7, it is assumed that pallets 48 are stored in all groups A to H, and all transmission devices 50 are moved separately.
In this state, when the pallet 48 of group A is taken out by the forklift vehicle 8 as shown in FIG.
Since the photoelectronic switch 101 of group A is not detected, the transmission devices 50 of groups A and B are connected and move, thereby conveying the pallet 48 of group B to group A as shown in FIG. Then,
Since the photoelectronic switch 101 of group B becomes non-detecting, the transmission devices 50 of groups B and C are connected, and the pallet 48 of group C is conveyed 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 the same procedure can be performed. You can sequentially feed three or more locations.

In the embodiment described above, the driven rollers 31 and the non-driven idling rollers 78 are arranged every other time, but this may alternatively be a configuration in which every second roller 31 is arranged. Furthermore, when one conveyor 10 is entirely driven by rollers 31, it is particularly suitable for pallets 48 made of resin.

In the embodiment described above, the conveyance device 12 is formed by a pair of left and right conveyors 10 and 11, and only one of the conveyors 10 is of a driven type, but this uses long rollers and is conveyed by only the driven conveyor 10. A device 12 may be formed.

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 transported to the installation site in unit units in which piping is constructed in the recessed portion. can be incorporated into. Therefore, it is easy to assemble shelving equipment and repair transport equipment.
Control piping can be done compactly at the manufacturing site. When in use, the transmission device is connected and moved to transmit the driving force of the drive body to the roller.
By forcibly rotating this roller, a pallet (load) can be conveyed, and by disengaging the transmission and disabling the roller, conveyance of the pallet can be stopped. At this 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 carried out regardless of variations in load or the material of the pallet.
Moreover, since the moving speed can be made constant, it is possible to carry out stable conveyance, and furthermore, it is possible to arrange horizontally, and the conventional dead space can be eliminated, thereby providing shelf equipment with high storage efficiency.
