Abstract

PROBLEM TO BE SOLVED: To always keep a jointed condition between the leading and trailing ends of a long body constant for prevention of the occurrence of an inferior jointed part by feeding a plurality of roll-shaped long bodies, which are retained at a plurality of shafts 3 coaxially on a rotating disc, while connecting them in order from the long bodies. SOLUTION: A plurality of shafts 3 are mounted coaxially on a rotating disc 1, and a long body 2 of roll shape retained at the shaft 3 positioned at the lower side is guided by a plurality of guide rolls 5 and is fed to the next packing process and so on. When it is confirmed visually or by a sensor that all the long bodies 2 of roll shape are worn and the trailing end part of the long body is delivered, a feed line is stopped temporarily. The leading end part delivered from the long part 2 of roll shape is pressed against the trailing end of the long body 2 of roll shape of the lower shaft 3 to be jointed by a vacuum chuck 7 together with a double-sided adhesive tape 8, and feed line operation is restarted. The disc 1 is rotated by 1/3 turn to repeat the same movement.

2. Description of the Related Art As an example of the use of a long body, for example, a long body is used as a packaging material, and a fluid content such as a powdered medicine, a liquid seasoning, and a powdered oxygen absorbent is used. A method for preparing the stored package and the like are mentioned, and various methods are further known for the method for preparing the package, and if one of these is specifically exemplified, the following method can be mentioned. . One of them is orthogonal to the longitudinal direction of the long wrapping material while facing the two wrapping material of the long wrapping material (hereinafter referred to as the long wrapping material or simply the long sized body) which is fed out and moving in the vertical direction. Seal the part that forms the lower part (lower edge) of the package and both sides of the long packaging material that forms the side of the package along the longitudinal direction, and fill the specified amount of content from the opening on the top After that, a so-called four-way seal that seals the opening is used to form a strip-shaped packaging body in which a large number of packaging bodies are arranged in series, and the obtained strip-shaped packaging body is used as a product as it is,
There is a method in which the product is cut into individual packages at the seal part. The other one is to fold a long wrapping material continuously in a horizontal state, fold it in half from the center in the longitudinal direction, and to fold it in the longitudinal direction at regular intervals with respect to a V-shaped wrapping material whose bottom is the fold. A predetermined amount of content is filled from the upper portion which is formed by opening the sealing portion which is orthogonal to each other, and then a so-called three-way seal that seals the opening portion of the upper portion is formed into a strip-shaped packaging body in which a large number of packaging bodies are connected in series. In the same manner as in the case of a four-sided seal, the obtained strip-shaped package is used as a strip-shaped package,
This is a method in which individual packages are cut at the seal portion.

As described above, the elongated body is widely used. However, even though it is an elongated body, its length is limited due to transportation and storage, and it is in a roll form. Although it is different from the material and the width, the total length is usually about 100 to 2000 m except for special ones. Therefore, as described above, when using the roll-shaped long body as a packaging material, when continuously producing a package, a plurality of roll-shaped long bodies are prepared and the rolls supplying the long body are provided. When the end of the elongated strip was approaching, the operator had to wait and connect the beginning and the end of a new roll-shaped strip prepared. Further, in order to make the connection without impairing the continuity of manufacturing, a shaft for supporting the roll-shaped long body which newly starts the supply of the long body is changed to the roll which is currently supplying the long body. It is necessary to provide it close to the long shaft so that the connection can be smoothly performed. However, if such a configuration is adopted, the two shafts always alternate between the roll-shaped long body being supplied and the spare roll-shaped long body, that is, for example, two shafts are used to feed the long-shaped body. In the case where the long body was supplied from the upper shaft first and the lower shaft was used as a spare in the case of being installed perpendicularly to the direction, the roll-shaped long body fixed to the upper shaft was consumed. After that, the elongated body is supplied from the lower shaft, and the upper shaft serves as a spare. In this way, the fact that the positional relationship of the shaft that holds the roll-shaped elongated body that supplies the elongated body is sequentially changed means that
It means that the positional relationship between the starting end and the terminating end of the long body at the connection point changes with each connection, that is, the starting end and the terminating end may go up or down, and as a result, the connection of the long body. In many cases, there was variation in the adhesive strength of the parts, and the connection part came off during operation, and the operation had to be stopped. To solve that problem,
Various means and measures are conceivable, but the adoption of these means and measures tends to make continuous supply of long bodies difficult or complicated, so a continuous supply method of long bodies without such problems is strongly recommended. It has been demanded. The present inventors have made various studies on means for solving these problems in view of the current situation.

[0004]

SUMMARY OF THE INVENTION The present inventors have found that these problems are caused by providing a plurality of shafts for holding a roll-shaped elongated body for supplying the elongated body concentrically on a rotatable disc. The inventors have found that they can be solved by means, and completed the present invention.

That is, according to the present invention, a long body from a plurality of roll-like long bodies held by a plurality of concentrically provided shafts on a rotatable disc is connected and supplied in sequence.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic view of a continuous feeding device of a long body showing an example of the device of the present invention. A disk 1 rotatable by a motor has a plurality of shafts 3 concentrically (three in FIG. 1). ) Is provided, and the elongated body 2 is supplied to the subsequent steps such as the packaging step while being guided to a plurality of guide rolls from the elongated elongated body 2 held by the shaft located below. On the other hand, when the roll-shaped long body held by the lower shaft is consumed, the shaft located above the shaft holding the roll-shaped long body for supplying the long body instead of the long body A preliminary roll-shaped long body for feeding the long body is held, and the leading end of the long body is led out and is waiting to be connected to the end of the long body being fed. Outside the disk, a double-sided adhesive tape 8 for connecting the end and the start of the elongated body, an adhesive tape cutting cutter 9 and an adhesive tape pressing tool 10 for attaching the cut adhesive tape to the beginning of the elongated body. A mechanism for connecting to the starting end of the elongated body is provided. Further, a vacuum chuck 7 is provided for pressing and adhering the start end of the long body to which the adhesive tape is attached and the end end of the roll-like long body held on the lower lower shaft.

From the continuous feeding device having the above structure,
The long body is continuously supplied by the following procedure. First, the long body is continuously supplied from the roll-shaped long body held by the shaft located at the lower portion. When all of the roll-shaped long body is consumed and the end of the long body is extended, the end of the long body is visually confirmed or confirmed by a sensor (not shown), the supply line is temporarily stopped, At the starting end of the long body that is fed from the roll-shaped long body held on the upper shaft, the starting end to which the double-sided adhesive tape has already been attached,
It is pressed and connected to the end by a vacuum chuck. At the same time as the connection is completed, the operation of the supply line is started and the elongated body is continuously supplied again. On the other hand, when the connection between the terminal end and the starting end is completed, the disk having the shaft holding the roll-shaped elongated body in a concentric circle is rotated one-third by a motor or the like (not shown) to move the elongated body to the previous position. The shaft holding the roll-shaped long body that had been supplied was moved to a position that was not directly related to the supply of the long body, and the paper tube (core) that remained due to consumption of the long body It is removed and a new roll-shaped long body is loaded. The removal of the paper tube and the loading of the roll-shaped elongated body can be automatically performed by interlocking with the rotation of the disc. Furthermore, the shaft that was loaded and held with a new roll-shaped long body moved to the upper part as the disc rotated,
When it is in a fixed position, it is rotated by a motor, and the elongated body is extended by a certain length to the guide roll. At this time, blowing air from the air nozzle to the part where the long body is wound is a preferable method because the long body can be smoothly fed. The starting end of the long body extended to the vacuum chuck is fixed to the vacuum chuck by the vacuum and is supplied from the roll-shaped double-sided adhesive tape.The double-sided adhesive tape cut to a certain length is fixed by the vacuum and rotated The double-sided adhesive tape is attached by an adhesive tape pressing tool that can be attached to the starting end surface of the long body. The release paper of the double-sided adhesive tape is removed from the surface by an operation such as blowing air. The roll-shaped long body held on the shaft having the starting end to which the double-sided adhesive tape is attached is held until the roll-shaped long body held by the lower shaft and supplying the long body is consumed. It is made to wait in the state. By repeating the above procedure, the long body is continuously supplied.
