Abstract

PURPOSE:To enhance operation rate by taking loads out from plural automatic warehouses formed with racks and take-in/out devices and carrying them in a common carrying device and providing a load shelter in its midway side portion. CONSTITUTION:By the contraction of the cylinder device 23 of an automatic warehouse 18A, a parting rail portion 20a on the load handling portion rail 20 side is connected to a main rail 21. (Other automatic warehouses 18B-18D are the same.) A self-running vehicle 25 which holds a load and comes from a former process is moved to the parting rail 20a, and the cylinder 23 is extended so as to be stored in a defined rack 1 through the load handling rail 20 by a take-in/out device 6. Delivery is the reverse. In this case, when the order of loads delivered from respective automatic warehouses 18A-18 is, for example, 5D, 5B, 5A, 5C and it is changed to the order of 5A-5D, preceding loads are sheltered in a load shelter 35 so as to make following loads pass and arrange the order.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is used to store and manage multiple types of cargo, take out the desired cargo in response to a command, and then transport it to the next process. This relates to equipment for changing the shipping order in automated warehouses.

Conventional technology In the past, this type of automated warehouse was
The structure of Japanese Patent No. 39984 is provided. In this conventional structure, an automated warehouse is configured by a pair of left and right shelves and a cargo delivery position located between these shelves, and a plurality of automated warehouses are arranged in parallel. Then, a shoot inlet conveyor is disposed outside the end of one shelf, a shoot out conveyor is disposed outside the end of the other shelf, and a common conveyor is provided that intersects between the outer ends of each conveyor. A load conveyor is installed.

Loading is carried out by transferring the load on the load conveyor to the shoot-loading conveyor, then receiving the load that has reached the end with the load transfer device, and then transferring it to the intended compartment storage space of both phases. . In addition, when unloading, the cargo is taken out from the compartment storage space targeted by the cargo delivery system and transferred to the shoot conveyor.
This is done by passing the load that has reached the end to the load conveyor.

Problems to be Solved by the Invention In the conventional configuration described above, there is no problem in randomly transporting the loads taken out from each phase to the next process by the load conveyor in the order in which they were taken out. However, if you want to take out cargoes of native seeds from each phase and then decide on the order of the species and transport them as one group to the next process, the order in which they are passed from each shoot output conveyor to the material transport conveyor must be controlled. As a result, the operating rate of the automatic storage system will decrease.

The purpose of the present invention is to efficiently take out loads from each automated warehouse to a transport device in a random manner without determining the order, and to rearrange the order of the loads in one group during transport to the next process. The purpose of the present invention is to provide a facility for changing the shipping order in an automated warehouse.

Means for Solving the Problems In order to solve the above problems, the present invention has been devised! The equipment for changing the output order in a warehouse consists of multiple automated warehouses consisting of shelves and loading/unloading devices, a common transport device for transporting the loads taken out from these automated warehouses, and a grape shelter on the side of this transport device. We have established a department.

According to the configuration of the present invention, the transport 81 from each automated warehouse
One group of loads randomly taken out above is transported to a load sheltering section by a conveyance device, and among the loads of one group, the loads whose ranking needs to be changed are taken out to the load sheltering section and evacuated - and the order is changed. By sending out the load from the load handling section onto the conveyance device based on the above and conveying the load on the conveyance device, it is possible to roughly replace the load into one group whose rank is determined.

Example An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a pair of shelves arranged side by side with a passage 2 placed thereon, each of which is composed of a frame body 3 and a number of holding rods 4 arranged from the frame body 3 toward the passage 2 side, and these holding rods 4 are cylindrical in shape. Loads 5A, 5B, and 50° 5D, shown as objects, are fitted and held inside. The loading/unloading device @ 6 arranged in the passageway 2 includes a traveling machine body 8 supported and guided by a floor rail 7, a lifting platform 10 supported and guided by a post 9 erected from the traveling vehicle body 8, and this lifting platform. 10
It is composed of a loading/unloading tool 11 provided on the top so as to be movable left and right, a traveling drive device 12, a lifting drive device 13, etc.
It can run freely along the front surface of the shelf 1. The loading/unloading shell 11 is installed on the lifting platform 10 so as to be able to move left and right. and a support arm 16.The automated warehouse 1 constructed in this way
88, 188.18C, and 18D are arranged in plurality (four in the embodiment) with the passage 2 parallel to each other.

To each your own! ll In the warehouses 18A, 18B, 18C, and 18D, a cargo handling section rail 20, which is shaped like a letter 0 in plan view, is placed between the outer ends of the storage shelves 1 in the warehouses 18A, 18B, 18C, and 18D. It is arranged as a height. Main rails 21 constituting a common conveyance device are disposed at the same level across the outer sides of the arcuate portions of the respective material handling section rails 20. The parallel parts of each material handling section rail 20 and the main rail 21 are formed in divided rail parts 20a and 21a, and these divided rail parts 20a and 21a are integrated by a connecting member 22, and are an example of a drive device.

By operating the cylinder device 23, it is possible to move freely in the parallel direction. Note that the connecting member 22 is supported and guided by a guide device 24. The self-propelled vehicle 25, which can run freely guided by both rails 20.21, includes a main body 26, a plurality of wheels 27 attached to the main body 26 to be placed on the upper surface of the rails 20.21, and the wheels. A traveling drive device 28 is attached to the main body 26 to be interlocked with the body 27 and can be driven in forward and reverse directions, a guide roller 29 is attached to the main body 26 to face the side surface of the rail 20.21, and a lower part of the main body 26. It consists of a load support rod 30 provided in the load support rod 30, etc., and this load support rod 30 is

5 has an annular rail 36, and the parallel part between the main rail 21 and the annular rail 36 is divided into rail parts 21b and 36.
b, and these divided rail portions 21b,
A cylinder device 38 is interlocked with a connecting member 37 in which the cylinder 36b is integrated.

Next, the warehousing work and the warehousing work in the above embodiment will be explained.

When performing warehousing work, for example, as shown in the example corresponding to the automatic warehouse 18^ at the upper end of FIG. connected to. The load is supported by the load support rod 30, and the self-propelled vehicle 25, which has traveled from the previous process while being supported and guided by the main rail 21, is transferred to this divided rail portion 20a and stopped. Next, by extending the cylinder device 23, as shown by the automatic color 418B at the lower end, the divided rail portion 20a supporting the automobile 25 is removed.
is connected to the material handling rail 20. Then, the self-propelled vehicle 25 is run forward or backward, and the intermediate automatic warehouse 188.18
It is stopped at the end of the material handling section rail 20 as shown by C. At this time, when one of the two ends is set as the warehousing side and the rest as the warehousing side, the self-propelled vehicle 25 is always driven to the warehousing side. If the vehicle is not set, the vehicle is caused to travel toward one of the ends, and when two self-propelled vehicles 25 are inserted one after the other, the vehicles are distributed to both ends and are caused to travel. After the self-propelled vehicle 25 is stopped at the end, the traveling body 8 is stopped, but this may be stopped in advance. Then, after the multistage extension/retraction tool 14 is moved to project in either the left or right direction and the support arm 16 on the projecting side is inserted into the cylinder,
By raising the lifting table 10, the load supported by the load support rod 30 is lifted by the support arm 16. Next, by moving the multi-stage ejector/retractor 14 in and out, the load is positioned on either side of the lifting platform 10. Further, once the self-propelled vehicle 25 is placed at both ends, the load is supported by the other support arm 16 by operating the multi-stage ejector 14 in the opposite direction. The loading/unloading device 6, which supports one or two loads with the loading/unloading tool 11 in this way, is stopped facing the target holding rod 4 by traveling of the traveling body 8 and raising and lowering of the lifting platform 10.

Then, by performing the reverse operation of the receiver described above, the load is fitted and held onto the holding rod 4. If there are two loads, transfer the other load by performing the same operation on the shelf 1 on the opposite side, either at this location or at another location where you have traveled and raised/lowered it. Ru.

The self-propelled vehicle 25, which has become empty due to receiving the cargo at the load/unloader @6, transfers to the divided rail section 20a by traveling in the opposite direction to that described above, and then connects the divided rail section 20a to the main rail 21. This main rail 21
I can go back to.

Note that the empty self-propelled vehicle 25 is not necessarily on the main rail 21.
There is no need to return it to the warehouse, and it may be kept on standby in the cargo handling section rail section 20 for the next delivery. At this time, it is also possible to store a plurality of empty self-propelled vehicles 25 on either end side, and in this case, one by one, the empty self-propelled vehicles 25 can be driven to the other end side as they are taken out. That's fine.

The unloading operation is similar to the warehousing operation described above. In this case, an empty self-propelled vehicle 25 is put into the cargo handling rail 20 from the main rail 21, and an actual self-propelled vehicle 25 is transferred from the cargo handling rail 20 to the main cargo handling rail 20. It is returned to the rail 21.

When the dividing rail section 20a is connected to the material handling rail 20 during the above-mentioned loading and unloading, the remaining dividing rail section 21a is also connected to the main rail 21. Therefore, the empty or real self-propelled vehicle 25 on the main rail 21 can be made to sequentially travel downstream via the divided rail portion 21a. Furthermore, since each automatic warehouse 188 to 180 has one shift section using the dividing rail 21a, etc., the distance between the shift sections of the main rail 21 can be increased, and this distance can be used to increase the distance between the shift sections of the main rail 21. The self-propelled vehicle 25 can also be stored.

Each automated warehouse 188 to 18D or different types of cargo 5
A to 5D are stored, and each automated warehouse 18A to 1
There are times when the loads 5A and -5D taken out one by one from 8D are transported to the next process as one group.

In this case, each [JIIfa warehouse 18A to 18D may be
Due to the difference in the cycle time of the loading/unloading device 6 depending on the position on the shelf 1 at which the loads 5A to 5D are taken out, one group transported by the main rail 21 is moved along the temporary line (see Fig. 1).
As shown in ^) and (B), the order of the six items 5A to 5D is different. In the next process, for example, 5A from the beginning as shown by the solid line FC) as one group of loads.
- If you want items in the order 5B-5C-5D, and a group of cargo is transported in the order 5D-5B-5A-5C as shown by the temporary line (8), do the following: Rankings will be coarsened. Note that in the following, the movement of the loads 5A to 5D is explained, and all of this is performed via the self-propelled vehicle 25. That is, in the load shelter part 35,
First, the leading load 5D is transferred to the dividing rail portion 36b, and then the load 5D is transferred to the annular rail 36. Similarly, the second load 5B is also placed on the annular rail 3.
6 and the state shown in the solid line in FIG. 3 is obtained. Then, as shown by the temporary line in FIG. 3, the third load 5A is passed by using the dividing rail 21b, and this is designated as the top. Next, the load 5B is separated by the circular movement of the annular rail 36 at the rail portion 36b.
After stopping at , it is returned to the main rail 21 and moved to the next process. Then, after passing the last load 5G using the divided rail portion 21b, the load 5D remaining on the annular rail 36 is returned to the main rail 21 in the same manner as described above. ), rearrange them into one group of the desired permutation.

Note that if the order of one group before reaching the load sheltering section 35 is as requested by the next process, the load is passed through without being replaced with silk at the load sheltering section 35.

In the above embodiment, the loads 5A to 5D are taken out one by one from each of the automatic warehouses 1188 to 18D to form one group. Sometimes they are grouped without
In addition, two or more items may be taken out from some or all of the automatic warehouses 188 to 180 and grouped.'lCKThe order of taking out as shown in Figure 1 (A) (B)
The ranking (C) after regrouping is an example, and the ranking FA) (
B) is always random as mentioned above, and the ranking (
C) is based on the requirements of the next process. Each automated warehouse 1
8A to 181) are centrally controlled by one control section, and the reassembly control of the load sheltering section 35 is performed based on this control.

In the above embodiment, the loads 5A to 5D made of cylindrical objects are handled by a suspended transport type self-propelled vehicle 25, but this is also a type in which a rectangular load is handled by a loading and conveyed type self-propelled vehicle. It may be.

Further, although a self-propelled vehicle system is shown as the conveying device, it may also be a conveyor system such as a bell 1 or a chain conveyor.

FIG. 4 shows another embodiment of the cargo receiving arm 35. As shown in FIG.

That is, the dividing rail 21b and the shunting rail portion 39 are integrated with the connecting member 37, and the connecting member 37 is connected to the cylinder device 3.
A plurality of sets connected to the main rail 21 are arranged in the direction of the main rail 21 so that each set can be operated independently.

Effects of the Invention According to the present Komei having the above-mentioned configuration, one group of loads randomly taken out from each automated warehouse onto the transport device is transported by the transport device to the load shelter section, and then the priority among the loads in one group is Loads that need to be changed can be taken out and evacuated to this load retracting section.

Then, by sequentially sending the cargo from the cargo shelter to the transport position based on the order, it is possible to
They can be rearranged into groups and transported. As a result, each person can take out loads from the vJ warehouse to the transport device at random without determining the order, and it is possible to increase the operating rate on the automated warehouse side.
