DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The same components as those of the conventional example are designated by the same reference numerals,
The description is omitted except when necessary.

FIG. 1 shows the first and second conveyors, which are the devices of this embodiment, while being cut (with slits).
A view of the winding rolls which are not separated from each other placed, the winding rolls are separated from each other, and the short pipe is removed in a direction perpendicular to the roll axis of the winding roll. Is the first
Of the take-up rolls 1 to 4 placed on the conveyor 7 which is the conveyor of FIG. 4, (b) is a view of the take-up roll 4 separated by the conveyor 8 which is the second conveyor, ( FIG. 2C shows a state in which the short tube 6 exposed in the gap between the separated winding rolls 4 and 3 is grasped by an arm 20 of another device and is being removed. FIG. FIG. 3 is a side view of the device 19, and FIG. 3 is a perspective enlarged view of the vicinity of the arm 20 of FIG.

In FIG. 1, reference numeral 7 denotes a first conveyor, which receives four unseparated winding rolls 1 to 4 which are still cut from a web winding device (not shown) and rolls of the winding rolls 1 to 4. It is provided so that it can be transported in the axial direction. A second conveyor 8 is provided in series with and independently of the conveyor 7, and can be operated and stopped independently of the conveyor 7. 15 and 16 operate conveyors 7 and 8, respectively.
A drive motor to be stopped, 20 is a short pipe removing device 19 described later.
It is the figure which showed typically only the arm 20 of.

Next, the operation of the above configuration will be described.

1 by the same means as FIG. 5 of the conventional example.
As shown in (a), after the winding rolls 1 to 4 are transferred onto the conveyor 7, the drive motors 15 and 16 of the conveyors 7 and 8 are simultaneously activated to move the winding rolls 1 to 4 toward the conveyor 8. .. When the take-up roll 4 is separated from the conveyor 7, the conveyor 7 is stopped. The conveyor 7 is stopped after the take-up roll 4 is completely transferred onto the conveyor 8. At this point, as shown in the state of FIG. 1B, the winding rolls 3 and 4
The space opens.

When a suitable gap is formed between the winding rolls 4 and 3 in this way, the conveyor 8 is also stopped. In FIG. 1, the short tube 6 remains on the winding roll 4, but of course the winding roll 3
You may leave it in

That is, which of the winding rolls 3 and 4 the short tube 6 is left to is free, and the short tube 6 and the core tube 5 for winding remain in the hardened eye. The conveyors 7 and 8 for transferring the take-up rolls 1 to 4 are widely known in the paper manufacturing industry together with their structures and control methods, and therefore description thereof will be omitted.

The short tube 6 remaining on the winding roll 4 is removed by the short tube removing device 19 shown in FIGS. However, the short pipe 6 may be removed manually.

Next, the short pipe removing device 19 will be described with reference to FIGS. In both figures, the arm 20 has a link 22.
It is opened and closed by the operation of the air cylinder 21 via. 32
The arm 20 is moved through the base 29 by the hydraulic cylinder 33 that operates the link 31 installed on the frame.
Move in the vertical direction indicated by.

Linear bearing guide 2 installed on the base 29
The pedestal 27 guided by 8 is moved by the air cylinder 30 in the axial direction of the take-up roll 4.

A guide rod 24 fixed to a support 23 of the arm 20 is supported by a bearing 25, and an air cylinder 26 moves the arm 20 in a direction perpendicular to the axis of the winding roll 4 as shown by an arrow B.

The arm 20 stands by above the center of the winding roll 4 at a position where the rod of the air cylinder 26 is retracted. When the take-up roll 4 stops on the conveyor 8, the air cylinder 26 first projects to the right in FIG. 2, and the arm 20 moves to the center position of the take-up roll 4 as indicated by arrow B.

Next, the rod of the hydraulic cylinder 33 operates in the pushing direction and the arm 20 descends in the direction indicated by the arrow C,
The short pipe 6 is stopped at a position where it can be clamped. Subsequently, the air cylinder 21 operates in the rod retraction direction and the arm 20 grasps the short tube 6. With the short tube 6 held by the arm 20, the air cylinder 30 is actuated to move the arm 2 through the mount 27.
The short tube 6 is pulled out from the winding roll 4 by operating 0 on the conveyor 7 side.

Next, the air cylinder 26 operates toward the rod retracting side, and moves the arm 20 in the direction indicated by the arrow D to the position of the short pipe receiver 34. At this time, the rod of the air cylinder 21 is actuated in the protruding direction, the arm 20 is opened and the short pipe 6 is released, and the short pipe 6 falls into the short pipe receiver 34.

Next, the air cylinder 30 is activated and the arm 2
0 moves in the advancing direction of the take-up roll conveyor. Further, in the height direction, the operation of the hydraulic cylinder 33 causes the arm 20 to move so as to be positioned above the short pipe 6 to be pulled out next time.

This completes one cycle of removing the short pipe 6. Since each operating point and operation control in the above operation can be easily performed by known means using a commercially available contactless switch, limit switch, photoelectric switch or other sensor and programmable logic controller,
No details will be given. When the removal of the short pipe 6 from the take-up roll 4 is completed, the take-up roll 4 is sent to the next step by the conveyor 8, and then the take-up roll 3 is received by the conveyor 8 and the short pipe 6 is removed by the same operation as described above. The same operation is sequentially carried out to remove the short tube 6 from the winding rolls 4, 3, 2 and separate the winding rolls 4, 3, 2, 1 individually. The hydraulic cylinder 33 and the air cylinders 21 and 26 do not specify their types. Other types of actuators may be used respectively.

In this embodiment, the short pipe removing device 19 is used as a means for removing the short pipe 6. However, the short pipe removing device may be carried out manually by an operator without using this device, or by another device. Good.

Further, for example, if the conveyors 7 and 8 are installed in advance such that the winding roll 4 is already placed on the conveyor 8 in a state corresponding to FIG. It is sufficient to operate the conveyor 8 alone while keeping 7 stopped to separate the take-up roll 4 from the take-up rolls 3, 2, 1 and is not necessarily restricted to the description of the operation of this embodiment. Even if the number of take-up rolls increases, it is free to install the first and second conveyors on a stand-by-position basis so that the first take-up roll always hangs on the second conveyor. Included in the present invention.

Further, the conveyors 7 and 8 do not necessarily need to include a stop operation. For example, a weight change detecting means and a speed changing means are provided in the conveyor 8, and the conveyors 7 and 8 are always operated at a constant speed, When more than half of the axial length of the take-up roll is transferred to the conveyor 8 and more than half of its weight is loaded on the conveyor 8, it is detected for a moment and the conveyor 8 is accelerated for a second time. Alternatively, the leading winding roll may be separated from the winding roll, and the short pipe removing device 19 may be automated so as to remove the short pipe 6 during that time. At that time, in order to ensure a sufficient separation gap between the first winding roll and the second winding roll, the conveyor 8 starts to accelerate when, for example, about 40% of the weight of the winding roll is loaded on the conveyor 8. However, it is also possible to increase the coefficient of friction of the conveyor 8 with respect to the take-up roll so that the conveyor 7 can be pulled away from the conveyor 7.

As described above, according to the present embodiment, the heavy unrolled take-up roll can be easily separated by the combination of the operations of the conveyors 7 and 8, so that the short pipe 6 can be easily removed. It has the advantage that it can be done.

Particularly, in the case of the present embodiment, since the short pipe removing device 19 is used for removing the short pipe 6, there is an advantage that all steps can be automatically and efficiently performed.

[0032]

Since the present invention is constructed as described above, it has the following effects. (1). In a winder that produces a winding roll by connecting a plurality of winding roll core tubes with a short tube inserted in the inner peripheral portion of the core tube, the short tubes can be easily removed from the winding roll. The productivity of the winding roll is improved. (2). Since the process of automatically removing the short tube mounted in the core tube for the winding roll can be automated, unmanned operation and labor saving can be achieved. (3). Safety is improved because no workers are required.
