Abstract

PURPOSE:To make storage efficiently performable in a narrow floor space, besides simplification in traveling drive, by traveling each carrier on a constant route by a common driver free of contact or separation, and performing the storage in a way of transferring it to vertical plural stages of gravity guide rails. CONSTITUTION:On a constant route 5, a carrier 4 receives traveling force from a driver 18, and travels after being supported and guided by a guide rail 1. At a notched part 35, the carrier 4 is transferred onto a relay rail 39 of a warehousing side transferrer 40 from a terminal of the guide rail 1, then transferred to a gravity guide rail 36. Then carrier 4 on the gravity guide rail 36 automatically travels to the terminal side with its own tilt and subjected to storage. Here, the carrier 4 supporting loads of the same type is warehoused in the same gravity guide rail 36 and assortment is also performable. Thus, storage is efficiently performable in a narrow follow space, besides simplification in traveling drive.

It transfers from the end of the guide rail to the relay rail of the warehousing side transfer device, and then moves to the gravity guide rail to which the relay rail is connected. The carrier on the gravity guide rail automatically moves toward the end due to its inclination.
Storage is performed sequentially starting from the end. When connecting the relay rail to the gravity guide rail, for example, by selecting the type of load supported, carriers supporting the same type of load can be stored on the same gravity guide rail for sorting. can also be done. To unload the carrier from the gravity guide rail group, first connect the intermediate rail of the unloading side transfer device to the terminal end of the selected gravity guide rail, and transfer the carrier from the gravity guide rail to the intermediate rail. This can then be done by connecting the intermediate rail to the starting end of the guide rail and transferring the carrier to the guide rail.

Next, the operation of the above embodiment will be explained.

On the fixed path (5), the carrier (4) travels under the moving force of the drive device (to). In other words, the carrier (
The passive part (a) of 4) is placed on the 10th rack, and at this time it is located above the upper surface of the gravity roller 0; also the guide rail 0), so the carrier ( 4
) side, the passive part OQ is strongly pressed against the 10th-ra wire, and the contact direction of the upper roller (8) to the upper guide surface (1a) and the lower guide surface (1b) of the lower roller αO are
) is in the opposite direction, so it is supported and guided without falling or wobbling. Therefore, as the roller chain (b) moves, the carrier (4) travels on a fixed path (5), but at that time, the third
As shown in the solid line in the figure, when the 10th line is caught by the 10th rule (goods), the 10th line is moved by the movement of the roller chain ■.
Since the -ra (4) frictionally rolls on the No. 1 rule (C), the carrier (4) has a forward feed rate due to the rotation of the large-diameter No. 10-R wire, which is equal to the moving speed of the roller chain @. It will be transported at a medium speed with added Also, as shown by the imaginary line in Figure 3, when the 20th rail (E) receives the 20th rail (E), the 20th rail (■) undergoes frictional rotation on the second rail (□□□) due to the movement of the roller chain slope. move, and this 20th-la (1
) is rotated at a higher peripheral speed (increased speed), and the carrier (4) increases the moving speed of the roller chain @ by increasing the circumferential speed. It will be transported at a high speed with the addition of forward feed speed due to accelerated rotation. Furthermore, as shown by the imaginary line in Figure 3, when the 30th rail (C3) is received at the 8th rail (to), the 30th rail (3+) is moved by the movement of the roller chain.
It rolls with friction on the rail, but since no rotational force is applied to the 10th rail, the rotation is stopped.
The carrier (4) supported by the wire will be transported at the same low speed as the roller chain.

Carrier (4) traveling at any of the speeds mentioned above
is stopped by a stopper device fi (57) at the end opposite to the cutout. The empty intermediate rail (to) is then lowered and connected to the end of the guide rail (1). Then, the stopper device (57) is moved in and out to move the carrier (4) onto the relay rail (to) and stopped at the stopper device @-. Note that carrier (4) follows a fixed path (
5) While traveling on the relay rail (to)
is in the connected state, the relay rail (G) may be transferred to the relay rail (G) without being stopped by the stopper device I (57). The carrier (4) escapes laterally outward, cutting off the transmission of running force. Also, the carrier (4) descends because the support provided by the 10th wheel is released. 89a), resulting in a slight descent.Then, the intermediate rail (A) is raised and connected to the starting end of the target gravity guide rail (to) of the gravity guide rail (7) group. Then, by moving the stopper device (7) in and out, the carrier (4) automatically transfers from the intermediate rail (to) to the gravity guide rail (7). When connecting to the gravity guide rail (1), by selecting the type of article (IQ), it is possible to connect the same type of article OQ (carrier R4) to the same gravity guide rail (to).
It is also possible to have them stocked and sorted. The carrier (4) that has transferred to the gravity guide rail (7) automatically travels to the end side due to its inclination and is caught by the stopper device (toward), or the carrier that has stopped in front (4) through the pan bar 00, and are sequentially stored.

Gravity Guide Rail (To) Carrier from Sen (4)
For unloading, first, the relay rail (51) of the unloading side transfer device (52) is raised and lowered to connect it to the terminal end of the selected gravity guide rail (to). And the stopper device (7
), the leading carrier (4) automatically moves to the relay rail (51).

At this time, the following group of carriers (4) also travels, but this is caught by the stopper device which projects again in conjunction with the tie ring. The carrier moved to the relay rail (51) (
4) is received by the stopper device (56), and after lowering the relay rail (51) and connecting it to the guide rail (1), the stopper device (56) is moved in and out to connect the guide rail ( Move on to 1). At that time, the passive part 0!
9 rides on the vehicle, and thereafter it travels on a fixed route (5) receiving power from the drive device 0→.

In addition, when transferring from the relay rail (a) to the gravity guide rail (to) and from the gravity guide rail (■) to the relay rail (51), each transfer device V (52) is It may be forced to travel by a provided transfer device (feeder).

In the above embodiment, the carrier (4) is shown as a trolley, but it may also be in the form of a hanging hanger. Further, the drive device may be of a chain type with a constant speed, and the contact may be of a dog type.

Effects of the Invention According to the present invention having the above configuration, each carrier is driven along a fixed path by a common drive device that can freely communicate with each other, and therefore, the traveling drive can be carried out in a simple manner, and the separation effect Storage can be done easily. Further, storage can be efficiently carried out in a narrow occupied space by moving to a plurality of gravity guide rails in the vertical direction, and sorting can be performed by making the product types the same for each gravity guide rail. Furthermore, the gravity type allows storage to take place automatically and without gaps between the carriers.
