Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for a flexible belt-shaped article such as a long thin sheet that is continuously conveyed, and in particular, a winding device that automatically winds the leading edge of a sheet onto a winding drum. It relates to a device for carrying out the process.

Conventionally, winding the leading edge of a sheet onto a winding drum has been performed manually, but this work involves the risk of fingers getting caught in the drum, etc., and is inefficient.

The present invention aims to eliminate the above-mentioned danger and improve the efficiency and accuracy of the work by mechanizing this work. When winding up with a winding drum (Surf Ace Roller), in order to lift the leading edge of the sheet onto the winding drum, a nozzle that blows out compressed air at high speed is installed. The feature is that the sheet is floated and caught by a liner that is previously transferred to the winding drum from an auxiliary roller in the winding direction, and the leading edge of the sheet is guided to the winding drum.

Next, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, 5 is a belt conveyor,
The belt conveyor 5 continuously conveys the sheets 6 from left to right. Reference numeral 1 denotes a winding drum (surf ace roller) for winding up the sheet 6, which rotates in contact with the belt of the belt conveyor 5, and is pivotally attached to the tip of an arm 8 that is pivotally supported on the machine frame 7. ing. Furthermore, arm 8 and machine frame 7
A hydraulic cylinder device 9 is interposed between the winding drum 1 and the belt conveyor 5, so that the winding drum 1 can be held at a position separated from the belt conveyor 5 when the winding drum 1 is not in use.

2 is a liner wound around the drum 10, which is made of cloth,
It is made of polyethylene, etc., and is wound together between sheets to prevent the sheets from adhering to each other when the sheets are wound up on a winding drum.
an auxiliary roller 3 disposed close to the winding drum 1 in the direction of movement of the belt conveyor 5;
The leading end of the winding drum 1 is wound in advance through the winding drum 1. Reference numeral 4 denotes a fluid ejecting means, which in this embodiment is a high-pressure air supply pipe, and is designed to eject air from a nozzle 11 at its tip to float the tip of the sheet 6. In operation, the sheet 6 is conveyed to the right by the conveyor. Immediately after the tip of the winding drum 1 contacts the winding drum 1 (the state shown in FIG. 2), a detector (not shown) detects this, and high-pressure air is ejected from the nozzle 11 in response to the signal. The tip of the sheet 6 is influenced by this ejected air and floats up (the state shown in FIG. 3).

In this state, the sheet 6 continues to move to the right, and as the nozzle 11 continues to eject the sheet, the leading edge of the sheet 6 rises along the winding drum 1, and eventually there is a gap between the liner 3 and the winding drum 1. It is held between the sheets (the state shown in FIG. 4), and thereafter is wound up together with the liner 3 onto the winding drum 1 (the state shown in FIG. 5). Note that in the state shown in FIG. 5, the air ejected from the nozzle 11 is no longer needed.
The supply may be stopped.

As explained above, according to the present invention, when a flexible belt-shaped article such as a long thin sheet that is continuously conveyed is wound onto a winding drum, the winding of the leading edge of the sheet onto the drum is automated. be able to.
Furthermore, since the liner exists between the strip-shaped articles, there is no risk of the strip-shaped articles adhering to each other. Therefore, by installing an automatic cutter and installing two winding drums in parallel, sheets of a certain length can be continuously cut.
It also allows for good winding.
Its practical effects are remarkable. Furthermore, by providing an auxiliary roller that wraps the tip of the liner around the winding drum in advance in the vicinity of the belt conveyor traveling direction of the winding drum, tension is applied to the liner to facilitate winding of the tip of the object to be wound. between the belt conveyor and the auxiliary rollers.
Further, in the traveling direction of the belt conveyor, only when winding the leading end of the material to be wound around the winding drum, a fluid ejecting means is disposed for ejecting fluid to the interface between the belt conveyor and the leading end of the material to be wound to make it float. This has the effect that the leading end of the object to be wound can be automatically and reliably rolled up without manual intervention as in the conventional case.

Claims (1)

[Claims] 1 Flexibility that allows the material to be wound up that is continuously conveyed on a belt conveyor to be continuously wound up with the liner being held between the winding drums that are pressed against the top surface of the material to be wound up. In the winding device for a belt-shaped article, an auxiliary roller is disposed near the winding drum in the direction of movement of the belt conveyor, and an auxiliary roller is provided to wrap the tip of the liner around the winding drum in advance;
Between the belt conveyor and the auxiliary roller, and only when the leading end of the material to be wound is wound around the winding drum, in the direction of movement of the belt conveyor, the boundary surface between the belt conveyor and the leading end of the material to be wound is What is claimed is: 1. A winding device for a flexible belt-shaped article, characterized in that it is equipped with a fluid ejecting means that ejects fluid to make it float.
