A pocket sorting system is to put items, such as clothes, in a pocket called a pouch, and then sort these items by type or number, and then pack them. refers to a set of systems.

It can be used when sorting and packing a lot of clothes in a large place such as a clothing warehouse. Accordingly, the pocket sorting system is also called a pouch sorting system.

On the other hand, in order to automate logistics by building such a pocket sorting system, an adapter with a pocket is required, and this adapter must move along a line such as a drive chain. At this time, considering the size of the pocket sorting system, it may be considered to use a chain made of metal.

However, considering that the pocket sorting system is a huge system structure that is installed on a ceiling in a wide place, when a long metal chain is connected and applied as a driving means, it is necessary to press-fit while applying a split pin or a snap ring. This is not an easy problem.

In addition, when a metal chain is applied, there is a problem that a large amount of driving force is needed unnecessarily due to a large weight, and there is a problem that a lot of difficulties in maintenance occur in that lubricants must be periodically sprayed.

Prior to a detailed description of the non-metallic prefabricated chain 520 , it will be described in turn from the warehousing station 100 . The storage station 100 forms a place where the goods are received through a pocket (Pocket) suspended from the adapter 540 (Adapter).

As mentioned for a moment before, the pocket sorting system according to this embodiment puts items such as clothing in a pocket called a pouch, and then sorts the items by type or number, and then packs them. It is a series of systems that

In such a system, a place for loading items such as clothing in a pocket is the wearing station 100 . For reference, the pocket circulates along the line hanging from the adapter 540 while supporting the clothing. Accordingly, the pocket of the packing station 300 forms an empty pocket, and when the empty pocket arrives at the wearing station 100 , a worker loads an article such as clothing into the pocket.

A packing station 300 is provided around the warehousing station 100 . The packing station 300 constitutes a place for packing sorted items. That is, when the goods stored in the warehousing station 100 are sorted through the sorting station 500 and then arrive at the packing station 300 , the worker residing in the packing station 300 packs the sorted goods.

The warehousing and packing lines 508 and 509 are provided so that the warehousing station 100 and the packing station 300 can be connected to the system logistics line 400 .

For example, when the volume of cargo is large, the adapter 540 may be temporarily stored in the buffer line 505 . Of course, in the present embodiment, since the first and second sorting lines 501 and 502 form a closed loop, if the packing operation is delayed due to a large amount of traffic, the article is not sent to the packing station 300 . The first and second sorting lines 501 and 502 may be continuously circulated.

The system logistics line 400 is a line disposed on the outside of the sorting station 500 and selectively connected to the sorting station 500 , and one side is disposed adjacent to the warehousing station 100 and the packing station 300 .

It is a partial cross-sectional view of a prefabricated chain and an adapter applied state, FIG. 6 is a horizontal state arrangement of a non-metallic prefabricated chain and an adapter, FIG. 7 is an inclined state arrangement of FIG. 6, and FIG. is an operation diagram of an adapter assembling (Accumulation) process, FIG. 10 is a structural diagram of a movable stopper unit, FIG. 11 is a cross-sectional view of a non-drive profile, and FIG. It is a partial cross-sectional view, Figure 13 is a horizontal arrangement view of the no-drive profile and the adapter, Figures 14 to 18 are diagrams for explaining the adapter branching unit, Figures 19 to 23 are diagrams for explaining the adapter joining unit, 24 to 28 are diagrams for explaining an adapter branching and merging unit, and FIGS. 29 and 30 are diagrams for explaining a chain driving unit.

Referring to these drawings, each line of the pocket sorting system applied to the system according to the present embodiment has a line for moving the adapter 540 with a driving force, and for moving the adapter 540 with the weight of the adapter 540 without driving force. is the line

In this embodiment, the first sorting line 501 , the second sorting line 502 , and the system distribution line 400 are driving lines for moving the adapter 540 with a driving force, and the third sorting line 503 and the buffer line 505 is applied as a no-drive line that moves the adapter 540 without a driving force. The warehousing and packing lines 508 and 509 may also be applied as non-driven lines.

The first sorting line 501 , the second sorting line 502 , and the system distribution line 400 as driving lines for moving the adapter 540 by driving force have substantially the same structure. That is, the first sorting line 501 , the second sorting line 502 , and the system distribution line 400 include a driving profile 510 to which a chain 520 that moves the adapter 540 by a driving force is coupled. In particular, the chain 520 at this time is applied as a non-metallic prefabricated chain 520 that can be disassembled and assembled.

When the non-metallic prefabricated chain 520 is applied, unlike conventional metal chains, installation work can be easily performed without split pins or snap rings, and the driving force can be lowered by weight reduction, and furthermore, maintenance work can be performed more easily than before. .

And, as described above, the third sorting line 503 including the warehousing and packing lines 508 and 509 includes a no-drive profile 530 that moves the adapter 540 without a driving force. In this case, the third sorting line 503 is inclined so that one end of the third sorting line 503 connected to the first sorting line 501 is higher than the other end connected to the second sorting line 502 . As described above, since the third sorting line 503 is disposed to be inclined, the adapter 540 having a constant weight may move with its own weight on the inclined third sorting line 503 . Therefore, it is not necessary to apply the third sorting line 503 as a driving line, and thus power loss can be reduced.

The adapter body 541 is provided with a barcode or RFID for identification information of the product. Accordingly, it is possible to sort articles according to predetermined information. A QR code may be used instead of a barcode.

An opening 541a is formed in a lower region of the adapter body 541 . A hanger-type pocket may be caught in the opening 541a. Of course, since the opening 541a is not necessarily formed, it should be said that the adapter of the type without the opening 541a also falls within the scope of the present invention.

An adapter head 542 having a constricted shape is formed at an upper end of the adapter 540 . The adapter head 542 is used as a place where the clamp 525 of the non-metallic prefabricated chain 520 is selectively hooked and connected as shown in FIGS. 6 to 9 .

One side of the adapter body 541 is provided with a bearing-embedded adapter wheel 543 .
