Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for packaging an annular bundle formed by winding an electric wire such as an indoor vinyl electric wire or a lead-in vinyl electric wire, or a linear body such as a thin pipe into a ring shape (coil shape). The present invention relates to a method and apparatus for doing so.

Generally, this type of circular bundle is wrapped with two pieces of paper or plastic tape, placed in a cardboard box, or wrapped in a heat shrink film. However, the method of wrapping with tape takes a considerable amount of time, the method of wrapping in cardboard requires expensive packaging materials and packaging machines, and the method of wrapping with heat shrink film has the drawbacks of being difficult to store and handle. Ta.

An object of the present invention is to provide a method and apparatus for packaging circular bundles that can be efficiently packaged using simple equipment and that are easy to store and handle.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 schematically shows a method of packaging a circular bundle according to the present invention, and this method is carried out as shown in FIG. 1 (A). The bundle 1 is placed on a sheet-like packaging material 2, and then, as shown in FIG. The annular bundle l and the packaging material 2 are lowered relative to each other, the packaging material 2 is squeezed into a cylindrical shape, and finally, as shown in FIG. It is horizontally moved by a pushing member (not shown) so as to wrap around the annular bundle 1a, and then pushed into the hole 1b of the annular bundle l to wrap the annular bundle l.

FIG. 2 shows a packaging device 1 suitable for carrying out the method of the invention.
As shown in FIG. 1(A), this packaging device 10 includes a table 14 that carries the annular bundle l placed on the packaging material 2 and is moved up and down by an air cylinder 12, and a A cylindrical restraining wall 16 restrains the packaging material 1 into a cylindrical shape, and the remaining portion 2a on the packaging material 2 squeezed into a cylindrical shape is attached to the upper surface 1a of the annular bundle l, as shown in FIG. 1(B). A plurality of pushing members 2 are arranged at intervals in the circumferential direction so as to be able to be moved horizontally by an air cylinder 18 so as to surround the cylindrical restraining wall 16, and to form an extension of the cylindrical restraining wall 16.
0. A transport table 22 is provided on the pushing member 20 to transport the annular bundle 1 while sliding it, and a transport hole 22 a is provided on the transport table 22 in alignment with the cylindrical restraining wall 16 .

Next, referring to FIG. 3, the state in which the method of the present invention is carried out by the packaging apparatus 10 shown in FIG. 2 will be described.
A) As shown in 4 and 9, the packaging material 2 is supplied onto the collar 20a of the pushing member 20 using a plurality of clips (not shown) from a supply of packaging material 2 wound into a coil (not shown), and 1 is cut by a cutter (not shown). . Next, as shown in FIG. 3B, the annular bundle l, which is the material to be packaged, is conveyed onto the conveyance table 22, and in front of it is raised to approximately the same height as the conveyance table 22, and the packaging material 2 is placed thereon. The transfer table 22 is placed on the table 14 through the carry-in hole 22a. Therefore, the annular bundle 1 is placed on the packaging material 2 and is exactly in the state shown in FIG. 1(A). Next, as shown in FIG. 3(C), when the table 14 is lowered in this state by the air cylinder 12, the packaging material 2 is restrained by the cylindrical restraining wall 16, so that the packaging material 2 is As shown in FIG. 1(B), it is squeezed into a cylindrical shape so as to wrap around the outer peripheral surface of the annular bundle 1.

Thereafter, as shown in FIG. 3(D), the pushing members 20 are moved radially inward by the air cylinder 18, so that the remaining portion 2a of the packaging material 2 is moved horizontally by these pushing members 20 into an annular bundle. When the table 14 is slightly raised as shown in FIG.
Since the remaining portion 2a of the packaging material 2 is pushed into the
As shown in C), the inner peripheral surface of the annular bundle 1 is completely wrapped. After wrapping the annular bundle 1 in this way, as shown in FIG.
As shown in (G), the table 14 is lowered,
The pushing member 20 is moved radially outward, and finally the table 14 is raised to the same height as the conveying table 22 or a slightly higher position as shown in FIG. 3(H), and the wrapped annular bundle is removed. Take out object 1.

According to the present invention, as described above, circular bundles can be automatically wrapped using simple equipment, so the work can be carried out economically and efficiently, and the packaging material is not limited, so storage and handling are easy. There is a real benefit in making it easier.
