Description
- The present disclosure relates to a rebar packaging method and a rebar packaging rectangular tray, and more particularly, to a rebar packaging method and a rebar packaging rectangular tray which are for easily loading and storing rebars.
- In general, rebars are mainly used to form the skeletons of structures in construction or industrial sites for the purpose of mechanical strength enhancement.
- Such rebars are manufactured in a bar shape or a roll shape having a predetermined length, and then used after bending the rebars in shapes corresponding to the shapes of corresponding structures in construction sites or processing plants. In addition, when bending a heavy rebar having a weight of 50kg or greater, it is not easy to manually bend the rebar, and thus a rebar banding device is usually used.
- Rebars manufactured using such a banding device are subjected to a process of collecting and packing a plurality of rebars before providing the rebars to customers, and then the packaged rebars are transported to customers.
- The process of loading rebars in a given space and the process of packaging and storing the loaded rebars are mostly performed by manpower, and thus a considerable time is required for loading and packaging rebars.
- As described above, since such loading and packaging processes are generally performed by manpower, the prices of rebars are high when rebars are supplies to customers.
- In recent years, attempts have been made to use automated facilities or the like when storing produced rebars. However, it may be inconvenient to load rebars having various shapes by using automated facilities, and it is difficult to automate all processes for packaging loaded rebars. Thus, such processes are still performed by manpower.

The upper ends of theside portions 122 of thesupports 120 may be bound together using a binding material (e.g., an iron strap) to maintain the state in which thesupports 120 are seated on therectangular tray 110. - In the operation of loading the
rebars 200, therebars 200 are loaded in such a manner that therebars 200 cross thecenter portions 121 of thesupports 120 which are spaced apart from each other. That is, therebars 200 are loaded on upper portions of thesupports 120 seated in theseating grooves 1111. In the present embodiment, therebars 200 are previously bent in a "U" shape, andcenter portions 121 of therebars 200 may be placed on thesupports 120 which are provided as a pair.

That is, while the wrapping machine rotates around therebars 200 and thesupports 120, the wrapping machine may wrap therebars 200 and thesupports 120 with thevinyl 300 as one unit as shown inFIG. 5 . - The separating operation is for separating the
rebars 200 and therebars 200, which are bound together as one use by using thevinyl 300, from therectangular tray 110. Specifically, as shown inFIG. 6 , thesupports 120 seated in theseating grooves 1111 are moved upward to separate thesupports 120 from theseating grooves 1111. At this time, therebars 200 are separated from therectangular tray 110 together with thesupports 120 in a state in which therebars 200 are supported on thecenter portions 121 of thesupports 120 and the sides of therebars 200 are wrapped with thevinyl 300. After the separating operation, therebars 200 and thesupports 120 may be moved to a storage location or delivered to a customer requiring therebars 200. - In addition, a label attaching operation in which a label (not shown) describing information such as specifications or dimensions of the
rebars 200 is attached to thevinyl 300 may be performed before the separating operation. However, instead of performing the label attaching operation before the separating operation, the label attaching operation may be performed after the separating operation. - According to the rebar packaging method of the present disclosure, it is possible to easily load
various rebars 200 and then packaging therebars 200, and thus the time required for loading and packaging may be reduced. - In addition, since rebar loading and packaging may be performed using an automated facility, time and efforts may be minimized compared with manual work.
- In addition, various types of
rebars 200 may be maximally loaded in a narrow area, and thus a space necessary for loadingrebars 200 may be reduced. - In addition, since additional boxes or containers are not needed for loading and storing
rebars 200, costs for transportation or the like may be effectively reduced. - In the above-described embodiment, an example in which rebars 200 are arranged in the
rectangular tray 110 is illustrated, but this is a non-limiting example. That is, as shown inFIGS. 7A to 8D ,rebars 200 may be arranged in various forms. - Specifically, as shown in
FIGS. 7A to 7D , ten, eight, seven, or sixrebars 200 may be horizontally arranged on therectangular tray 110. In this case, therebars 200 having a "U" shape may be arranged in a zigzag form according to the size of therebars 200 such that therebars 200 may be arranged side by side at slight intervals for dense arrangement in a given space. - In addition, as shown in
FIGS. 8A to 8D , it is also possible to horizontally arrange five, four, three, or tworebars 200 in various forms. In particular, inFIGS. 8C and 8D ,bent feet 200a which are bent inward are provided on ends of therebars 200, and therebars 200 are arranged in an overlapping manner in which eachrebar 200 is spaced apart fromadjacent rebars 200 such that thebent feet 200a are not in contact with each other. - In addition, the shapes of rebars are not limited to the shapes described above, and examples of rebars include a
rebar 201 having a stirrup shape as shown inFIG. 9A , arebar 202 having a cap bar shape as shown inFIG. 9B , andrebars - In addition, the shapes and arrangements of rebars are not limited to those described above, and design changes for various shapes and arrangements are also possible.
- While embodiments have been described with reference to the accompanying drawings, these embodiments are for illustrative purposes only, and it will be understood by those of ordinary skill in the art that various changes and other equivalent embodiments may be made therefrom within the scope of the invention that is defined by the following claims.
