Description

[Detailed description of the invention] [Industrial application field]

This invention improves logistics efficiency and work efficiency by making the transport of goods between each distribution line a town function when a plurality of distribution lines are arranged in parallel, through which goods carried in are carried out after a predetermined operation. Concerning logistics methods for improvement.

[Conventional technology]

The logistics system to which the conventional method is applied will be explained with reference to Figure 3. FIG. 3 is a layout diagram of this logistics system. In Figure 3, two distribution lines are installed side by side. Each distribution line consists of the same receiving station 1, 11, branching station 2, 12, work station 3, 13, shipping station 4, 14, and temporary storage station 5, 15, respectively. Work station 3.13
, temporary storage station 3.13 each consists of five working rooms and five storage rooms. For example, in the case of work station 3, work rooms 3at 3bt 3c+
3d. Including 3e. The following transport means are in charge of transport between each station. That is, between the receiving stations l, 11 and the branching station 2.12, the automatic guided vehicles 6, 16 pass through the branching station 2.12 via the work station 3.13.
and shipping stations 4 and 14 are conveyors 7,
A crane 9.19 is in charge between the branch station 2.12 and the temporary storage stations 5 and 15, respectively. The outline of the logistics is as follows. To describe the distribution line on side 1 in FIG. 3 as a representative example, articles are transported to receiving station 1 by an external conveyance means such as a truck, and
The work is done in any of the work areas 38 to 3e, and the shipping stage is
4, from where it is removed by another external transport means. A control device, which will be described later, specifies for each article which workshop it is to be worked on, and the article is delivered to a receiving station corresponding to that workshop. In addition, when the designated work area is occupied and is in use, the item is temporarily stored in one of the vacant storage rooms of the temporary storage station 5 by the crane 9 from the branch station 2, and the designated work area is made available for use. I'll have to wait until then. The control device will be explained with reference to Figure 2. Second
The figure shows the configuration of a control device in a logistics system to which the method according to the present invention is applied, and is common to conventional methods. In FIG. 2, various commands and information as will be described later are input to the general control section 40, and calculation results are output to each transport command section 60, 70, and 80. Each transport command unit 60
, 70, and 80 respectively control the operation commands for the automatic guided vehicle 6.16, the conveyor 3.13, and the crane 9.19, and specifically, the automatic guided vehicle 6.16, the conveyor 3.13, and the crane 9.19.
Instruct each crane 9.19 the starting and ending points for transporting each item. Further, the display unit 50 displays the main input and output states of the comprehensive control unit 40. By the way, regarding the input to the comprehensive control unit 40,
S is designation information of a workplace or an alternative workplace for each item, and U is arrival information, which is a signal from a sensor installed at each loading station that indicates which item has been transported to which receiving station. ■ is the vacant information of the workshop, W is the vacant information of the storage room, which workshop. This is a signal from a sensor installed in each storage room as to whether or not it is empty.

[Problem to be solved by the invention]

The conventional technology described above works well when the imported goods are worked on at the work site of the distribution line, but problems arise when the goods have to be worked at the work site of another distribution line for some reason. Become. In other words, in FIG. 3, the article was initially delivered to the receiving station 1 with the assumption that it would be worked on at the work station 3a, but due to a change in the situation, the corresponding work station was moved to the work station 13c on a different distribution line.
When the change was made to the above, it became a problem as transport between logistics lines was not possible. If you try to force it, automatic guided vehicle 6
The article is transported from receiving station 1 to branching station 12 at receiving station l. In addition to requiring construction work to lay tracks between the branching stations 12, there are problems such as the automatic guided vehicle 6 not being able to carry out the original transport, which impedes logistics efficiency, and reducing work efficiency by delaying the original transport of goods. occurs. The object of this invention is to solve the problems that exist in the conventional technology, and to be able to transfer goods between distribution lines even when work is reassigned to a distribution line different from the distribution line into which the goods were brought in. The objective is to provide a logistics method that can improve logistics efficiency and work efficiency.

[Means to solve the problem]

In order to solve this problem, the logistics method according to the present invention includes a logistics line in which a receiving station, a branching station, a work station having one or more workplaces, and a shipping station are arranged in series in the above order. A plurality of the above are arranged in parallel; between the loading station and the branch station in each distribution line, and the branch station passing through the work station. First and second transport means respectively responsible for transporting between shipping stations are installed; a temporary storage station belonging to each distribution line and consisting of one or more storage chambers is placed near the branching station; A third conveying means related to the storage station is installed; the articles carried into each of the receiving stations are not temporarily stored in any of the storage rooms of the temporary storage stations of the distribution line to which each of the receiving stations belongs. In the method in which work is carried out at one of the workstations, either directly or after passing through, and then transported to the next shipping station, in a common vicinity with temporary storage stations belonging to each of the distribution lines adjacent to each other. A delivery station is arranged at each of the receiving stations; each of the third conveying means is in charge of passing through each of the temporary storage stations and between branch stages and delivery stations on both sides thereof; articles carried into each of the receiving stations are Transported from the branch station of the distribution line to which the receiving station belongs via the corresponding delivery station to at least the adjacent branch station,
directly from this branch station without undergoing temporary storage in one of the corresponding temporary storage stations.
After that, the work is carried out at one of the work stations corresponding to the branch station, and then the work is carried out to the next shipping station.

[For use]

As a normal form of distribution, when work is designated at a certain workplace, the goods are delivered to the receiving station of the distribution line to which that workplace belongs, and are transported by first and second transport means to a branch station and then to a temporary storage station. Either directly without temporary storage in one of the storage rooms, or after that, it is transported to a designated work station or an alternative work site, and after the designated work there, it is transferred to the next shipping station. transported. If the designated workplace belongs to a distribution line different from the receiving station, the incoming goods will be transported to the branch station corresponding to the receiving station, and from there each 38th
After being transported between lines by the I transport means to a branch station of another distribution line via the corresponding delivery station, it is transported by the second transport means to a designated or substitutable work site, and after the work there, the next The products are transported to the shipping station. In addition, when a designated or alternative workspace is in use and unavailable, incoming goods will be sent through a branch station to one of the available storage rooms at the temporary storage station, where they will be temporarily stored until the previous workspace becomes available. Stored.

[Actual 8% Example] An application example of the distribution method according to the present invention will be explained below with reference to the drawings. Figure 1 is a layout diagram of a logistics system. In the figure, the differences between this logistics system and the conventional example shown in Figure 3 are:
The delivery station 10 is placed at an intermediate position that is common to and near the temporary storage stations 5.15 of each adjacent distribution line; ■ The crane 8.18 as the third transport means passes through the temporary storage station 5. There are two points: between the branching station 2 and the delivery station 10, which pass through the temporary storage station 15, and between the branching station 12 and the delivery station 10, which pass through the temporary storage station 15. The other units are the same as the conventional example,
The same symbols as in Fig. 3 are given. The operation of this logistics system is as follows. In a normal physical distribution system, for example, when work is designated at a workplace 3d, the goods are delivered to the receiving station 1 of the distribution line to which the workplace 3d belongs, and the automatic guided vehicle 6 as the IVi transport means and the second transport By the conveyor 7 as a means, the transfer is carried out via the branch station 2 directly without temporary storage in any storage room of the temporary storage station 5, or after that, to the designated work area 3d of the work station 3, or alternatively thereto. It is transported to a possible work station 3e, and after a predetermined work is performed there, it is transported to the next shipping station 4. At this shipping station 4, the items that have undergone the specified work wait to be transported by truck. If the designated workshop belongs to a distribution line different from receiving station 1, for example, if it is workshop 13d, the incoming goods are transported to branch station 2 corresponding to receiving station 1, and from there a crane as a third transport means 8 and 18, and is transferred between the lines to the branching station 12 of the adjacent distribution line via the corresponding delivery station 10, and then transferred to the designated workplace 13d or an alternative workplace 13e by the conveyor 17 as the 21st transport means. After the work is done there, it is transported to the next shipping station 14, where it waits to be unloaded. Note that when the designated workplace 13d or the alternative workplace 1.3e is in use and unavailable, the imported articles go through the branch station 12 and are transferred to the temporary storage station 15.
In any of the available storage rooms, the previous workshop 13d
Or it will be temporarily stored until 13e becomes available. Therefore, the delivery of articles is not necessarily limited to the receiving station of the distribution line to which the work site to be worked belongs, but may be carried in to either receiving station 1 or 11. This increases the degree of freedom in transporting goods; for example, there is no need to wait until a receiving station becomes vacant, and you can freely select an available receiving station when you want to transport goods, which improves logistics efficiency and ultimately Helps improve work efficiency.

【Effect of the invention】

In this invention, it is possible to transfer goods between each distribution line, so even if the incoming goods are designated to be worked at a work station that belongs to a different distribution line from the receiving station where they were brought in, Stacein. After passing through the delivery station, the goods can be transferred to another distribution line and work can be carried out at a designated or substitutable workplace. For example, there is no need to wait until a receiving station becomes vacant, and you can freely select an available receiving station when you want to deliver goods, thus improving logistics efficiency and work. Efficiency can be improved.
