Description

[0001]
[Industrial application fields]
The present invention relates to a web winder used in a paper mill or the like, and more particularly to an apparatus for automatically supplying a core to a web winder.
[0002]
[Prior art]
In a paper mill or a paper processing plant, a web winding device generally called a winder or the like is used to rewind a winding roll made by winding paper or to obtain a small winding roll.
[0003]
The general structure of this web winding device is shown in FIG. The winding device of this figure is a type in which the winding roll 2 is wound up in a zigzag plane arrangement on both sides of the winding drum 1, and is frequently used in recent papermaking relations. Explaining the schematic structure, the web 4 is unwound from a large take-up roll (mill roll) 3 set in the unwinding section, and the web 4 is slit by the slitter 5 and divided in the width direction. The divided web 4 is supplied to the outer periphery of the winding drum 1, wound around a core (winding core) 6 that is in contact with the winding drum 1 in a pressurized state and is rotating together. The winding rolls 2 are formed in a zigzag plane arrangement on the left and right.
[0004]
When the winding roll 2 is gradually thickened and reaches a predetermined winding length, the winding device is stopped, the support arm 7 supporting the core 6 is turned, and the winding roll 2 is lowered onto the floor. Further, it is transferred onto a transfer conveyor. On the other hand, the winding device supplies the core 6 for the next winding roll to the winding unit while the support arm 7 turns and lowers the winding roll 2. Although there is a type that is directly supplied to the take-up unit manually, an automatic core supply device that automatically supplies the core from the core storage device is used recently without using the manual operation.
[0005]
Next, an example of an automatic core supply apparatus will be described. Since the basic structure of a conventional apparatus is similar to that of the present invention, the description will be given with reference to FIGS. 1 and 2 of the present invention. This automatic core supply device takes out the core from the core storage device 14 installed beside the winding device, and places the core on the recesses of the slide rails 8 installed in two rows above the winding drum 1. It has a configuration in which it is slid and supplied one by one. When all the cores have been supplied onto the slide rail 8, the two slide rails 8 (core holding portions) pivot around the take-up drum 1 with the core 6 held in the recesses to the position near the take-up position. Then, the chucking nose 12 of the core support device 11 waiting here is inserted into the end of the core, and the setting of the core is completed.
[0006]
As another example of the automatic core supply device, after all the cores have been supplied onto the slide rail above the winding drum 1, the core is gripped from above by the gripping device (core holding unit), and the arm remains gripped. There is also a model in which the core setting is completed by inserting the chucking nose of the core supporting device that is waiting here and moving to the vicinity of the winding position.
[0007]
However, in the example of FIGS. 1 and 2, the slide rail 8 rotates around the winding drum 1 to the winding position with the core 6 held in the recess, and the chucking nose of the core support device is inserted into the core. In the process up to this point, the problem that the core 6 falls from the slide rail 8 is likely to occur. This problem is particularly likely to occur when there are a plurality of core types and the same slide rail 8 is used for many types of cores.
In addition, the method of gripping the core from above has an operation of replacing the gripping device in accordance with the core outer dimensions, which deteriorates the work efficiency.
[0008]
[Problems to be solved by the invention]
The core holder of the conventional automatic feeder has the following problems to be solved.
The first problem is that the outer diameter of the core is not one type, and there are a plurality of main types such as 3 inches, 6 inches, and 12 inches. It is necessary to replace the core holding part such as a gripping device, and efficient operation cannot be performed.
[0009]
The second problem is that when the core is supplied, there is a case where the core is not sufficiently held in the core holding portion and the core cannot be reliably set on the core support device 11. For example, the problem that the core 6 falls from the slide rail 8 before the slide rail 8 turns around the winding drum 1 to the winding position with the core 6 held in the recess and passes it to the core support device. Occurs.
The second problem is related to the first problem, and supply troubles such as core dropping are the same for multiple types of cores, focusing on efficiency when there are multiple types of cores. This is particularly likely to occur when using a core holding part (slide rail 8, gripping device, etc.).
[0010]
An object of the present invention is to solve these problems, and can be used in common for cores having different outer diameters, and causes troubles such as dropping when moving while holding the core. It is to provide an automatic core supply device having no core holding part.
[0011]
[Means for Solving the Problems]
