Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for easily winding thin long sheet material such as house vinyl for farming, film material, cloth and the like.

(Prior Art) Conventionally, the winding work of a long sheet material such as house vinyl outdoors is done manually because a large sheet winding device used in a factory cannot be used. A device for rotating a winding core with a roller and winding a long sheet on the winding core or a device for guiding a sheet with a roller and winding the sheet around the winding core is disclosed in Japanese Utility Model Publication No. 60-180255 and Japanese Utility Model Publication No. 180255. 56-28086
It is disclosed in the publication.

(Problems to be solved by the invention) In the conventional manual winding method, the distortion of the winding of the sheet is corrected with two workers who manually rotate and support a winding pipe of about several meters. It was necessary to have two or more workers arranged at the required positions on the side edge of the seat, and a total of four or more workers. In addition, the actual development of Sho 60-18025
The winding core of the sheet winding device disclosed in Japanese Utility Model Publication No. 5 and No. 56-28086 is located in the vicinity of the roller inside the apparatus main body. Therefore, the sheet is introduced into the main body of the device, the sheet comes into contact with the roller and other parts of the machine, and the sheet is damaged,
There is a problem in that it may be difficult to smoothly wind up a sheet by being entangled in a roller or a mechanical member. This was a big problem especially in the case of agricultural work sheets in poor condition.

(Means for Solving Problems) The present invention solves such problems and enables a small number of people to wind a long sheet material, and the wound sheet does not come into contact with the main body of the apparatus or the roller, and the operation is smooth. (EN) It is intended to provide a practical long sheet material winding device capable of winding a sheet on a sheet, and also capable of carrying the apparatus easily and inexpensively. The gist of the invention is to dispose a pressing roller that rotates to a position where an upper space of the pipe feeding roller can be opened above a pair of pipe feeding rollers having a short width, and to rotate one or both of the pipe feeding rollers. At the same time, an adjusting lever mechanism is provided that allows the height of the pressing point of the pressing roller to be adjusted freely.In addition, one end of the pipe that serves as the winding core of the long sheet material is inserted between the pair of pipe feed rollers and the pressing roller. Further, there is provided a long sheet material winding device in which the other end of the pipe is supported by a pipe supporting member arranged at a position far away from the main body of the device. Here, the pipe feeding roller and the pressing roller may be those which can rotate the pipe with a required friction, and may be those with tires and knurls.

(Operation) In the present invention, the adjusting lever mechanism is operated to rotate the pressing roller to a position distant from the space above the pair of pipe feed rollers. After that, one end of a pipe, which is a long sheet winding core having a required diameter, is placed above the pair of feed rollers, and the other end is rotatably supported by the pipe support member. After that, the adjusting lever mechanism is operated to rotate the pressing roller to bring it into contact with the upper portion of the pipe, and rotatably support the pipe in cooperation with the pair of pipe feeding rollers. Next, one end of the long sheet material is wound or adhered to the pipe. Then, one or both of the pipe feed rollers are rotated by a prime mover or manually. When the pipe feed roller is rotated, the pipe rotates due to its friction and automatically winds the sheet material.
At the side edge of the sheet material, there are about two workers who move the sheet to adjust it so that the sheet is distorted and wound properly.

The diameter of the pipe as the winding core used in the present invention can be used by adjusting the pressing position of the pressing roller as long as the diameter is within the required range regardless of size.

(Example) In the present example shown in the drawings, two devices are arranged on the hand truck (1) on the left and right sides, and the pipe feed rollers (3) are rotated simultaneously by the engine (2) of the truck (1). I have to. or,
Wheels with tires are used as the pipe feeding roller (3) and the pressing roller (4). Further, the adjusting lever mechanism (5) includes a substrate (50) to which the pressing roller (4) is attached, a pivot shaft (51) rotatably pivoting the substrate, and a lever extending rearward from the substrate (50). (52), a rear wall plate (54) having a long slanted through hole (53) penetrating through the lever, and a spring (55) for urging the lever downward. The rotation of the motor (2) is transmitted by the chain (6) and the left and right pipe feed rollers
Rotate the common rotating shaft (7) of (3). The other axis of rotation (8)
Are linked by another chain (9) and the two pipe feed rollers (3) are rotated in the same direction. on the other hand,
The presser roller (4) is freely rotatable. The pipe supporting member (12) has a pipe receiving portion (13) whose tip is branched in a Y shape and can rotatably support the pipe, and its lower end is tapered so that it can be pierced and fixed in a field. A step is provided.

Note that another example is shown in FIG. This pipe support member
The reference numeral (12) has a Y-shaped pipe receiving portion (13), the lower end of which is embedded in the concrete block (14) so as not to move under the weight of the concrete block (14).

In this embodiment, when the lever (52) is pushed upward along the through hole (53), the presser roller (4) is rotated upward around its pivot axis (51), and the pipe feed roller (3) is rotated. Open the space above. Place the pipe (10) on it and open the lever (52).
When it is moved downwards (53), the presser roller (4) rotates and comes into contact with the pipe (10), and the spring (55) causes the pipe (10) to move.
Press (10) to secure the required frictional force. Pipe (1
The other end of (0) is placed on the pipe receiving portion (13) of the pipe supporting member (12). After that, the long sheet material (11) is wound around the pipe (10) a plurality of times by hand, or lightly adhered with cellophane tape or the like. Next, drive the motor (2) and chain (6), (9)
The pipe feed roller (3) is rotated by the pipe (10)
Rotates to wind the sheet material (11).

In this embodiment, the left and right sheet materials (11) can be wound simultaneously by operating the two right and left units at the same time. Also, this device and the pipe support member pipe etc. can be placed and moved on the hand truck (1), and can be transported very quickly and easily.
The ridges can be easily moved.

In the figure, (15) is a remote control wire for adjusting the rotation speed of the engine (2), (16) is a pipe stopper, and (17) is a pipe holding arm.

(Effect of the Invention) As described above, according to the present invention, the winding work of a long sheet material can be considerably mechanized, the number of workers can be efficiently performed, and the device can be simple and compact. There is an effect that it can be easily transported and moved, and the sheet material winding operation can be efficiently performed by an inexpensive device. In addition, the diameter of the winding pipe can be used even if the diameter of the winding pipe is somewhat large or small. Further, since the pipe serving as the winding core is located at a position largely separated from the main body of the apparatus, the sheet does not come into contact with the main body of the apparatus and the roller, so the sheet can be smoothly wound.
