The bottle 9 is held by rotary sleeves 7, 8 by both ends. At a position where the tip of an air- permeable sheet 1 more or less has passed the top of the bottle 9, the first frame 3 rotates, and the second frame 6 rotates successively, and the belt 10 covers almost the whole periphery of the bottle 9, and when the belt 10 is driven in the direction shown by arrow D, the sheet 1 is wrapped on the bottle 9.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method for handling breathable sheets such as highly breathable paper, cushion sheets, and porous sheets. The attached items are related to the equipment.

The present invention is particularly suitable for use as a device used in the packaging process for bottles, but is not limited thereto.

In addition, the air permeable sheets to which the wrapping device of the present invention is applicable are not limited to packaging paper, but include Japanese paper for various uses, shrink paper, mesh-like films, cloth, plastics, wire mesh, etc.
It can be applied to all types of breathable sheets such as other porous materials.

[Prior Art] When packaging glass bottles, etc., thick, porous, and highly air permeable paper is used to increase cushioning properties and protect the bottle. Bottles that contain various beverages or alcoholic beverages and are made into products at factories are packaged for cosmetic and protection purposes in the final process. Conventionally, the work of packaging bottles using such breathable sheets has been carried out manually by workers.

[Problems to be Solved by the Invention] Wrapping the breathable sheet around the bottle by hand is a cumbersome packaging operation and has poor production efficiency.

On the other hand, devices or winding devices that automatically process various types of thin sheet materials and... Automatic winding equipment has not yet been developed.

The present invention has been made in view of the above-mentioned problems of the prior art, and aims to provide a device for winding a breathable sheet that can automatically and reliably wrap the breathable sheet around a cylindrical body such as a bottle. shall be.

[Means for Solving the Problems] In order to achieve the above object, the breathable sheet wrapping device according to the present invention wraps the breathable sheet along the circumferential direction of a cylindrical body around which the breathable sheet is wrapped. a first frame that supports the continuous belt so as to be able to approach and separate from the cylindrical body; and a second frame that allows the end of the belt to approach and separate from the cylindrical body.

[Operation] When the cylindrical body is attached, the first frame moves to a position close to the cylindrical body and engages the continuous belt with the cylindrical body. Subsequently, the second frame moves toward the cylindrical body and engages the end of the continuous belt with the cylindrical body, thereby engaging the continuous belt over substantially the entire circumference of the cylindrical body.

The breathable sheet is transported and wrapped around the cylinder by a continuous belt. After the winding is completed, the second frame first separates from the cylindrical body, and then the first frame separates from the cylindrical body.

[Example 1] FIG. 1 is a perspective view of an apparatus for winding a breathable sheet according to the present invention. A breathable sheet 1 with thick cushioning properties for packaging is wound and fed in the direction of the device 2 as indicated by arrow A. The winding device 2 includes a first frame 3 pivotally connected to a first rotating shaft 4 and a second frame 6 pivotally connected to an end of the first frame 3 via a second rotating shaft 5. are doing. The first frame 3 can move toward and away from the bin 9 by rotating around the first rotating shaft 4 in the direction of arrow B. The second frame 6 can move toward and away from the bin 9 by rotating in the direction of arrow C about the second rotating shaft 5 as the center Φ.

The bin 9 to which the breathable sheet 1 is to be wrapped is the rotating sleeve 7
．． 8, both ends are held and supported in a predetermined position.

A continuous belt 10 that is driven in the direction of the arrow is attached to the first frame 3 and the second frame 6.

Next, the operation of the winding apparatus having the above structure will be explained with reference to FIGS. 2 and 3.

The breathable sheet 1 is conveyed in the direction of arrow A, and the leading end reaches the top of the bin 9 and stops at a position slightly beyond this. Here, the first frame 3 rotates around the first rotating shaft 4 in the direction of arrow B to bring the continuous belt 10 into contact with the bin 9. Subsequently, the second frame 6 rotates around the second rotating shaft 5 in the direction of arrow C to bring the end of the continuous belt 10 into contact with the bin 9. As a result, the continuous belt 10 contacts and covers almost the entire circumference of the bottle 9 (FIG. 3). In this state, by driving the continuous belt 10 in the direction indicated by the arrow, the breathable sheet 1 is rotated and wound together with the bottle 9 in the direction indicated by the arrow. If the frictional force between the breathable sheet and the cylinder around which it is wrapped is small, the cylinder may be fixed without rotating and only the breathable sheet may be transported along the circumference of the cylinder by a continuous belt. .

When the winding operation is completed, first, the second frame 6 is rotated around the second rotating shaft 5N8 in the direction away from the bottle 9 (in the direction opposite to arrow C) to separate it from the bottle 9, and then the first frame 3 is moved away from the bottle 9. It is rotated around the first rotating shaft 4 in a direction away from the bottle 9 (in the direction opposite to arrow B) and separated from the bottle 9. As a result, the entire device 2 is separated from the bin 9 for winding (a continuous bell) 1
0 leaves bin 9.

FIG. 4 shows the overall flow in the case where the winding of the breathable sheet as described above is automated and the bottles are packaged using an apparatus.

FIG. 4(a) shows the step of taking out the breathable sheet. The take-out lever 13 is an adhesive tape 1 attached to a breathable sheet 1.
This breathable sheet 1 is taken out through 2. The breathable sheet 1 taken out is transferred to the packaging position of the bottle 9 (FIG. 4(b)). The breathable sheet 1 is released from the take-out lever 13 at a predetermined position on the stage 17. The breathable sheet 1 is then sent to the wrapping device 2 and automatically wrapped around the bottle 9 as described above. In this case, the adhesive tape 12 attached to the breathable sheet 1 may be cut and removed by appropriate means. When double-sided adhesive tape is used, the adhesive tape can be used as it is for fixing after wrapping the breathable sheet.

The breathable sheet 1 wrapped around the bottle 9 further has a fourth
As shown in Figure (C), the tip is pinched by a squeezer 20 and rotated together with the bottle 9 to twist the sheet at the tip of the bottle 9 and fix the package.

[Effects of the Invention] As explained above, the present invention includes a continuous belt that moves along the circumferential direction of a cylindrical body around which a breathable sheet is to be wrapped, and a frame that supports this continuous belt is attached to the cylindrical body. On the other hand, since it is configured to be able to approach and separate in two stages, the continuous belt can be easily and reliably engaged around the entire cylindrical body, and the breathable sheet can be smoothly wrapped around the cylindrical body, resulting in high reliability. Automatic winding is accomplished.
