Abstract

PURPOSE:To secure a constant speed transport and facilitate the assembly and servicing of a transport device by providing a pair of right and left roller type conveyors inside multi-stage compartment storing spaces horizontally in the depth direction of transport, and providing a drive device, free to connect and disconnect, on either one of the conveyors. CONSTITUTION:Conveyors 10, 11 in respective compartment storing space 7 connects a supply and discharge hose 95 to an air supply source by the switch- over of a solenoid valve to extend a cylinder unit 56 and moves a pivot shaft 70 upward to press a transmission roller 72 against a roller 31 from the under side. In this case, since chains 41 are always driven by a motor, a sprocket 71 is rotated around a shaft 70 and, since the transmission roller 72 is pressed against the roller 31, the roller 31 is rotated forcibly. A load is thereby moved inside each compartment storing space 7. When the connection of an air hose to the supply and discharge hose 95 is interrupted by the switch-over of the solenoid valve, the load is stopped in movement.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides for storage of backs directly or via pallets;
This relates to shelving equipment that is used to take out items as needed.

2. Description of the Related Art Conventionally, this type of shelving equipment has been used, for example, in

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. In addition, some pallets cannot be used depending on the material of the pallet, for example, in terms of R friction resistance. 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.

As mentioned above, the conveyor system consists of a pair of conveyors IO and IL. 112, for example, as shown in FIG.
A plurality of groups in the conveyance direction 13, with six (plurality) arranged in a predetermined arrangement as one group, 8 groups A in the embodiment,
B, C, D, E, F, G, H are arranged, each group A
The transmission device 50 can be freely connected and disconnected for each period of .about.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 9G.・Can be shut off freely. 99
1 is a regulator, and 100 is a silencer. A photoelectronic switch 101, which is an example of a stock detector, is provided at the downstream end of each group A to H. 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 of both groups are in the detecting state or non-detecting state at the same time, the transmission devices 50 in both groups are configured to simultaneously shut off the MeC air supply hose 98 and the supply/discharge hose 95.

To this end, each solenoid valve 96 has 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. 103 indicates a stopper.

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, which has passed through the through hole 28.92 from below, through the nut 27.91. At that time, when the conveyance path 46 is long,
Each conveyor 10.11 is joined lengthwise. However, things like Cheno 41 are shared.

Next, the storage and conveyance work 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 9B to the supply/discharge hose 95, the support shaft 70 is swung upward by the expansion of the cylinder device 56 due to air pressure, and the transmission roller 72 is 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
It is supported between the rollers 31 and idle rollers 78, 88 of both conveyors 10.11, and is conveyed on this conveyance path 46 while receiving the conveyance force due to the forced rotation of the rollers 31 group. At this time, the idle roller 7 that is not driven
8.88 group 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 photoelectronic switches 101 of group H are detected, but the photoelectronic switches 101 of group G are not detected. Connect and group H.

The roller 31 of G is forcibly rotated, thereby conveying the pallet 48 from group H to group G. pallet 48
enters group G, the optoelectronic 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 connect and operate, moving the pallet 48 from group G to group F. transport to. The pallets 48 that have been sequentially conveyed to the downstream side in this manner come into contact with the stoppers 103, stop, and are stored in group A.

Then, when this pallet 48 is detected by the optoelectronic switch 101, the transmission device 50 of group A is separated and moved. The second pallet 48 is also 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, the transmission device 50 of group B is also moved separately. 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 moved separately. When the pallet 48 of group A is taken out by the forklift truck 8 in this state 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, when the pallets 48 of group A are being sequentially fed from group E to group D, by taking out the pallets 48 of group A, 2f! Sequential feeding can be performed at location B, and sequential feeding can be performed at three or more locations in the same way.

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.

Effects of the Invention According to the present invention having the above-mentioned configuration, both conveyors can be transported to the site and installed in a shelf frame in a unitized state with each conveyor frame. Therefore, assembly of the shelf equipment and repair of both conveyors can be easily performed. During use, a barret (load) supplied to the upstream end of the conveying device is conveyed toward the downstream end by forced rotation of rollers to which the driving force of the driving body is transmitted via a transmission device. This allows pallets to be fed sequentially and stored densely from the downstream end to the upstream side.

In this way, the pallet can be forcibly moved, and reliable movement (progressive feeding) can always be performed regardless of variations in load or the material of the pallet.

Moreover, by being able to keep the moving speed constant, it is possible to carry out stable conveyance, and furthermore, it can be arranged horizontally.
It is possible to eliminate the conventional dead space and provide shelf equipment with high storage efficiency.
