Abstract

PURPOSE:To continuously and automatically wind up a sheet-like material, by providing a cutting device for cutting the secured sheet-like material before and after the joint section thereof. CONSTITUTION:When a photoelectric tube 81 detects a joint section 2c, a nip 93 is pressed against a guide roller 91, and therefore, the posterior sheet-like material 2b is secured. Thereafter, the joint section 2b is clamped between a retainer plate 34 and a guide plate 31 to be secured, and further, the wind-up of the preceding sheet-like material by a spool core A is stopped, and a cutting device 40 is moved, so that the sheet-like material is cut in front and rear of the secured joint section 2c. At this time, even if the wind-up is interrupted, a treatment device does not stop it operation so that the posterior sheet-like material 2b is continuously fed, and therefore, the posterior sheet-like material 2b is reserved by a fabric reserving machine 52 which lowers a dancer roller 83. Then, a pusher 57 pushes the leading end of the posterior sheet-like material 2b into between a spool core B and a winder 74, and then the nip 39 is moved upward to release the fixing of the sheet-like material 2b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a winding device that divides a sheet-like material into a plurality of windings and winds them up. More specifically, the present invention relates to a winding device that connects a plurality of windings in sequence and, for example, divides a sheet-like material that has been continuously processed in a processing device into a plurality of windings and winds them around a core.

[Prior Art] Conventionally, when dividing fabrics, leather-like sheets, plastic sheets, etc. into predetermined lengths and winding them up, continuous sheets without joints are measured with a length meter to determine the predetermined length. The winding is performed by cutting each core and replacing the winding core sequentially. When processing such a sheet-like material that is divided into a plurality of pieces and wound, the trailing end of the preceding sheet-like material that has been unwound from one core to the processing device is then coated with another core. The front end portions of the trailing sheet-like material unwound from the winding machine are joined, the sheet-like material is sequentially and continuously processed, and then the sheet-like material is divided into a plurality of pieces again and wound around a winding core.

Such winding operations mainly rely on the work of workers, but in particular, the work of dividing the sheet-like material again and winding it up is entirely done by the workers, and the number of sheets to be joined is small, and If the diameter of the roll is not very large, the sheet-like materials are first wound onto one core while being joined, and then each sheet-like material is separated and re-wound. If the joint part is compressed by the winding of the sheet-like material, or if the length of one sheet-like material is long, or if the diameter of each roll becomes large, the sheet-like material may be The object is unjointed at the joint, or cut before and after the joint, and then divided into individual sheet-like objects and rolled up. This method is generally adopted especially for fabric and leather-like sheets.

[Problems to be Solved by the Invention] With conventional winding devices, when winding up joined sheet-like materials, the worker monitors the joint and either unravels the joint or cuts the joint before and after the joint. Then, the work of winding it onto each core was performed.

However, replacing the core in this case requires a long period of monitoring, and if the sheet material is wide or soft, it may be necessary to cut the joint and insert a new core. There was a problem in that the workability of winding was poor and that a large number of workers were required due to the need for rapid processing.

The present invention was made to solve the above-mentioned problems, and provides a sheet-like article having joints.

To provide a winding device for a sheet-like material that can continuously and automatically cut the work of cutting before and after a joint part and winding it around a new core, thereby reducing manual labor and labor, and further enabling automatic continuous operation. With the goal.

[Means for Solving the Problems] In the sheet-like material winding device according to the present invention, the joint portion between the preceding sheet-like material and the following sheet-like material sent out from the processing device reaches the first position. a first detector for detecting the occurrence of a change in the number of sheets;
a winder that receives a signal transmitted from the first detector and moves the winding core of the trailing sheet material to a winding start position; and detects that the joint has reached a second position. a second detector; a fixing device that receives a signal transmitted from the second detector to fix the sheet-like object at a second position; and a fixing device that cuts the fixed sheet-like object before and after the joint. and a winding device that winds the leading end of the trailing sheet-like material, which has been cut by the cutting device, around a winding core.

[Function] In the present invention, the first detector detects that the joint between the leading sheet-like material and the trailing sheet-like material has reached the first position, and the first winder Upon receiving the signal transmitted from the first detector, the core of the trailing sheet material is moved to the winding start position, and the second detector detects that the joint portion has reached the second position. Then, the fixing device receives the signal No. 43 transmitted from the second detector and fixes the sheet-like object at the second position, and the cutting device cuts the sheet-like object fixed by the above-mentioned fixing device at the joint part. The winding device wraps the leading end of the trailing sheet material after it has been cut by the cutting device around the core of the trailing sheet material.

Therefore, the winding work of the sheet-like material is performed automatically and continuously, and there is no need to wait or monitor the above-mentioned joints.
In addition, the burden on the workers is reduced because the manual work is reduced.
