Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a winding device capable of individually and safely unloading a winding roll of a belt-shaped body such as a paper web.

[Prior Art] For example, a wide web is cut in a width direction by a slitter and wound on cores arranged on both sides of a winding drum.

In recent years, with increasing speed of printing technology and the like, the winding diameter of the winding roll tends to increase, and the weight of the winding roll also increases more and more.

Therefore, the work of removing the heavy take-up roll from the take-up device and placing it on the table requires careful attention.

Conventionally, as shown in FIG. 7, when winding of the winding roll a is completed, the lifter b below the winding roll a rises,
Place the take-up roll a with the stopper c protruding,
Next, the table is returned to the same height as the table d, the stopper c is pulled in, and the winding roll a rolls on the table d and is discharged.

[Problems to be Solved by the Invention] However, in the take-up roll a in which thick and thin paper is taken up, the take-up diameter becomes uneven between the take-up rolls a or within the take-up roll a, and is constant over the entire width. In the lifter b which rises to the height of, the thin portion of the paper is fogged and cannot be lifted by the lifter b, and it is difficult to remove from the winder.

Further, since the lifter b moves up and down by the fluid pressure cylinder f, it does not always have a stable structure, and if the winding diameter of the winding roll a becomes uneven as described above, an unbalanced load is applied to the lifter b, so that it is safe. There was a problem in terms of stability and mechanical stability.

Further, the lifter b had substantially the same length as the winding drum e, and even if the number of the winding roll a was one, the entire lifter had to be moved up and down.

The present invention is intended to solve the problems of the conventional lifter described above and to enable the individual winding rolls to be unloaded stably and reliably.

[Means for Solving the Problems] The present invention provides a pair of substantially horizontal support frames that extend in a zigzag pattern on both sides of the winding drum in a direction orthogonal to the axial direction of the winding drum. A plurality of pairs are arranged so that they can be tilted downward around the end on the side, and a roll support that supports the take-up roll and that can adjust the nip pressure is provided on each pair of support frames as the take-up roll becomes thicker. It is provided so that it can move away from the take-up roll, and a tilting fluid actuator that can tilt the support frame in the vertical direction is connected to each support frame. Furthermore, a rotation angle detection that can detect the tilt angle of each support frame And a distance detector that can detect the roll diameter of each take-up roll supported by each support frame in a non-contact manner so as to be movable in the axial direction of the take-up drum. Based on the detection signals from the measuring device and the distance detector, an arithmetic and control unit is provided to send a signal for safely and reliably landing and unloading each winding roll according to the roll diameter to the tilting actuator. I chose

[Operation] The maximum winding diameter of each winding roll after winding is individually detected by the non-contact distance detector, and the tilt amount of each support frame pair is adjusted by the tilting fluid pressure actuator, resulting in different winding diameters. The take-up roll can be individually unloaded.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention, which is arranged on both sides of a take-up drum 1 so as to form a striped pattern, and a pair of support frames 3 are arranged at intervals larger than the width of the take-up roll 2. , 3 ′
So that they can be rotated parallel to each other in the vertical plane,
Piston rods 7, 7'of fluid pressure cylinders 6,6 'pivotally attached to the base frames 5,5' by 4'and pivotally mounted on the base frames below the supporting frames 3,3 '. Pins 8 and 8'are connected to the undersides of the support frames 3 and 3'to allow the support rods 3 and 3'to rotate by the protrusion and retraction of the piston rods 7 and 7 '.

The pins 4, 4'of the supporting frames 3, 3'are attached to the pins 4, 4 '
A pinion 12 fixed to the detection shaft 11 of a rotary type rotation angle detector 10 by providing arcuate gears 9 around 4,4 'respectively.
Is engaged with the gear 9.

Winding roll supports 13, 13 'are arranged on the respective support frames 3, 3'movably over substantially the entire length in the longitudinal direction. The support
13, 13 'have a chuck device for holding the take-up roll 2, and by changing the moving speed on each support frame 3, 3', the nip pressure applied to the take-up roll 2 being taken up is changed. I can adjust it.

Further, below the take-up drum 1, an endless rail 14 such as a belt or a chain is provided over substantially the entire length of the take-up drum 1 between a drive wheel 16 driven by a motor 15 and a driven wheel 17 that freely rotates. The non-contact distance detectors 19 and 19 'by ultrasonic waves, laser beams, etc. are respectively wound on the winding rolls 2 which are wound around the blocks 18 and 18' provided at equal division positions of the length of the endless rail 14. Mounted toward the winding roll 2, the distance to the surface of each winding roll 2 is detected, the distance signal is wirelessly transmitted to the arithmetic controller 20, and the arithmetic controller 20 calculates the diameter of the winding roll 2 from the distance.
The hydraulic unit 22 is capable of controlling the amount of withdrawal of the piston rods 7, 7'of the fluid cylinders 6, 6'and the nip pressure by the supports 13, 13 '. Reference numeral 23 in the figure denotes a rotation speed detector.

With the above-described structure, the winding roll support members 13, 13 'on the support frames 3, 3'arranged on both sides of the winding drum 1 are arranged.
When the endless rail 14 is rotationally moved by the drive wheel 16 while the strip 21 such as a paper web is wound around the core supported by the core 18, the blocks 18, 18 'fixed to the endless rail 14 are not in contact with each other. The distances to the respective winding rolls 2 are detected by the distance detectors 19 and 19 'in the width direction.

If the detection distance to each winding roll 2 is constant within each winding roll 2, it indicates that the winding roll 2 is wound with a uniform winding diameter in the width direction.

If the winding distance is not constant in each winding roll 2, a portion with a large detection distance indicates a small winding diameter, and a portion with a small detection distance indicates a large winding diameter. The moving speed of the bodies 13, 13 'is adjusted by the arithmetic controller 20, the nip pressure is increased, and the winding diameter of the winding roll 2 is made uniform in the width direction.

While winding, the endless rail 14 continuously rotates,
Since the positions of the non-contact position detectors 19 and 19 'are always confirmed by the rotation amount of the motor 15 that drives the drive wheels 16 detected by the rotation speed detector 23, each support for supporting each winding roll 2 is supported. Precise instructions are sent to the bodies 13 and 13 '.

When the distance detected by the non-contact position detectors 19 and 19 'becomes less than a certain value, it means that the winding diameter of each winding roll 2 has reached the planned winding diameter, and thus the winding is completed. To do. The arithmetic controller 20 calculates the maximum winding diameter for each winding roll 2 from the detected distance, and calculates the tilting angles of the support frames 3, 3 ′ necessary for unloading each winding roll 2. By pulling in the piston rods 7, 7'of the fluid pressure cylinders 6, 6'by the hydraulic unit 22, the respective support frames 3, 3 'are tilted downward, and the rotation of the respective support frames 3, 3'rotates. When the detected angle is detected by the angle detector 10 and the detected angle coincides with the tilting angle for unloading, the retraction of the piston rods 7, 7'is stopped, and the winding rolls 2 are moved to the table 25 by removing the chucks at both ends. Is unloaded on top.

As described above, since the positions of the non-contact position detectors 19 and 19 'are always confirmed, the maximum diameter is detected for each winding roll 2,
Calculated and hydraulic cylinders 6, 6'of each support frame 3, 3 '
The support is sent for each and the individual winding rolls 2 having different winding diameters can be unloaded.

FIG. 4 and FIG. 5 show another embodiment of the present invention, in which the non-contact distance detectors 19 ″ are directed toward the winding rolls 2 on both sides of the winding drum 1 in a configuration similar to that of the above embodiment. This is an example in which the head can be swung and can be reciprocally moved below the winding drum 1 along a rail 24.
In the figure, the same reference numerals as those in FIGS. 1 to 3 indicate the same elements.

Also in the case of this embodiment, the winding diameters of the winding rolls 2 can be made uniform individually as in the case of the above-described embodiment, and the winding rolls 2 can be unloaded based on the maximum diameter.

The winding device of the present invention is not limited to the above-described embodiment, but as shown in FIG.
19, 19 'may be movable in a vertical plane, the non-contact distance detector may be arranged at the rear or above each winding roll, the tilting means of the support frame, the roll support The means for moving the body may be other means,
Needless to say, various changes can be made without departing from the scope of the present invention, such as being applicable to winding and unloading of belt-shaped bodies other than paper webs.

[Advantages of the Invention] As described above, according to the winding device of the present invention, the pair of support frames are tiltably disposed by the tilting fluid pressure actuator on the side of the winding drum, and the roll diameter of the winding roll is increased. Since the distance detector that detects contactlessly is arranged so as to be movable, the widthwise maximum winding diameter of each winding roll is detected after the winding is completed, and the tilt angle of each support frame is calculated, It is possible to unload different take-up rolls individually and securely, prevent damage to the surface layer of the take-up roll and rupture of the take-up roll due to collision at the time of landing, and take-up the take-up roll at high speed. It becomes possible. Further, since the distance detector is provided so as to be movable in the axial direction of the winding drum, it is possible to control the landing of all the winding rolls with a small number of distance detectors. Further, since only the pair of support frames that support the take-up roll are tilted, power energy is significantly reduced as compared with the conventional full-width lifting. Further, during winding of the take-up roll, non-uniformity of the take-up diameter of the take-up roll can be individually detected, so that the take-up diameter can be corrected by adjusting the nip pressure and the like.
