Description

[Detailed Description of the Invention] The present invention relates to a take-up roll rotation device that can be applied to a web winder.

Figure 1 shows a typical example of a web winder (hereinafter referred to as a winder) in the paper and pulp industry, and Figure 2 shows a typical example of a web winder (hereinafter referred to as a winder) in the paper and pulp industry.
1 is a detailed view of a main part of the figure, showing a conventional take-up roll rotation device. Now, in Fig. 1, part a shows the paper unwinding part, part b shows the slitter part, part c shows the winding part, and part d shows the roll unloading part.The structure of this winder is widely known in the industry and will be described in detail. do not. When the winding operation is completed in the winder, the paper is cut from the winding roll 01 at right angles to the paper flow direction and taken out to the roll unloading section d.

In the roll unloading section d, the ends of the paper are taped so that the cut portions of the paper do not unwind and cause trouble when the take-up roll 01 is handled in a subsequent process. Taping is done in a fixed position, but if the take-up roll diameter does not change or the tape-fastening position of the take-up roll is not in an easy-to-work position due to space constraints, the take-up roll 01 may be rotated and taped. Place it in a comfortable position.

Next, in FIG. 2, the cushion roll 04 is rotated upward by a cylinder 05 about the axis of the rotary roll 03. When the take-up roll 01 comes in in this state, the cushion roll 04 moves downward while absorbing the rolling energy of the take-up roll 01 with the pneumatic (or hydraulic) cylinder 05, and the take-up roll rotates. It stands still between the roll 03 and the cushion roll 04. In this state, the roll 03 is rotated by the electric motor 06 via the chain 07, and the take-up roll 01 is rotated by the required amount and then stopped. After that, take-up roll 01
Tape it on. The tape-bound take-up roll 01 pushes the push roll 08 upward by a pneumatic (or hydraulic) cylinder 09 and is transferred to the take-out conveyor 10 . At this time, Stopparol 11 was
Pneumatic (or hydraulic) cylinder 12 centered around fulcrum 14
It is pushed forward via the arm 13.
Next, the take-up roll 01 collides with the stopper roll 11 and comes to rest on the take-out conveyor 10 while the rolling energy is absorbed by the cylinder 12.

However, the conventional roll rotation device has the following drawbacks. In other words, the number of rolls is large;
The structure is complicated and expensive, a distance is required between the tape fixing position and the take-out conveyor, and a minimum space is required for installing the cushion roll.

The present invention was proposed in order to eliminate the above-mentioned drawbacks of the conventional technology.The present invention has a rotating function and is capable of supporting the transferred winding roll and rotating the winding roll. It is rotatably installed at the tip of the arm that can rotate around the fulcrum and has the function of absorbing shock and fixing the stroke at any position in the middle of the stroke. It is equipped with a roll that receives the roll, receives the winding roll pushed out from the winder drum without impact, and moves the winding roll by an arbitrary fixed amount to a position where it is easy to tape the end of the winding roll paper. The purpose of the present invention is to provide a take-up roll rotating device that can be rotated and then moved onto a conveyor after taping has been completed, thereby greatly reducing the installation space, making the device simple and inexpensive. be.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 3 to 7 show embodiments of the present invention. In addition, in FIGS. 3 to 7, the same parts as in FIGS. 1 and 2 are indicated by the same reference numerals. Now 01

Reference numeral 11 denotes a stopper roll, which is rotatably attached to an arm 13, and the arm 13 is attached to a fulcrum 14.
It is supported by a bearing 24 and is rotatably provided around the center. A fixed frame 15 supports the pneumatic cylinder 23 and the bearing 24. Also sprocket 2
0 is fixed to the shaft end of the roll 03, and a sprocket 21 paired with the sprocket 20 is fixed to the shaft end of the reduction motor 06. Pneumatic cylinder 23
is swingably pinned to the bracket 26 and pinned to the arm 13 at a fulcrum 25. This pneumatic cylinder 23 can be mechanically stopped and held in the middle of a stroke, and is a commercially available product generally referred to as a lock cylinder. The bearing 24 rotatably supports the arm 13 and is fixed to the fixed frame 15. Further, the bracket 26 swingably supports the cylinder 23 and is fixed to the fixed frame 15.

30 is a mechanical locking mechanism of the pneumatic cylinder 23, and when pneumatic pressure is applied, the lock of the rod is released.
It is designed to automatically lock when air pressure is removed. In addition, 31 is a proximity switch, and the pneumatic cylinder 2
This is to detect the intermediate stop position of rod extrusion No. 3. 34 is a 2-position 3-port electromagnetic switching valve for pneumatic pressure, 35 is a commercially available volume booster valve for pneumatic pressure, 36 is a pressure reducing valve for pneumatic pressure, 37 is a 2-position 5-port electromagnetic switching valve for pneumatic pressure, and 38 is a pneumatic switching valve. A speed regulating valve with a check valve for pressure, 39 a flow regulating valve for pneumatic pressure,
40 is a pressure reducing valve for pneumatic pressure. Note that A, B, C, D, and P of the electromagnetic switching valves 34 and 37 indicate connection port positions. Further, 41 is a check valve for pneumatic pressure.

Next, the operation of the embodiment configured as shown in FIGS. 3 to 7 will be explained. As shown in FIG. It moves. At this time, the stopper roll 11 is pushed out to the frontmost position. As shown in FIG. 7, compressed air is supplied to the pneumatic cylinder 23 through a port PA of an electromagnetic switching valve 37, set by a pressure reducing valve 36, and applied to the rod retracting side through a volume booster 35. At this time, compressed air is sent to the mechanical lock mechanism 30 through port PA of the electromagnetic switching valve 34 to release the lock mechanism.

In this state, the take-up roll 01 is the stopper roll 1.
1, the stopper roll 11 retreats while absorbing the rolling energy of the take-up roll 01. The load acting on the stopper roll 11 is transferred to the pneumatic cylinder 2 through the arm 13 and the fulcrums 14 and 25.
3 to operate the rod to the extrusion side. At this time, the air on the cylinder head side of the pneumatic cylinder 23 is rapidly compressed and pressurized, and escapes from the volume booster valve 35. Conversely, the air on the cylinder end side of the pneumatic cylinder 23 rapidly expands and its pressure drops, and the air is sucked in through the check valve 41.

After absorbing the rolling energy of the take-up roll 01, the electromagnetic switching valve 37 is switched so that port PB is connected. Then, the pressure of the air on the cylinder head side of the pneumatic cylinder 23 is increased by the volume booster valve 35.
The compressed air set by the pressure reducing valve 40 is sent to the cylinder end side of the pneumatic cylinder 23 at a flow rate adjusted by the flow rate adjustment valve 39 so that the pressure is slightly higher than the exhaust pressure of the compressed air. As a result, the pneumatic cylinder 23 slowly moves toward the rod extrusion side, and the stopper roll 11
Slowly retreat. When the piston of the pneumatic cylinder 23 comes to the intermediate position of rod extrusion, this is detected by the proximity switch 31. Based on this detection signal, the electromagnetic switching valve 34 is switched so that ports A and B are connected.

As a result, the compressed air sent to the mechanical lock mechanism 30 is discharged to the atmosphere from the B port of the electromagnetic switching valve 34. This allows the mechanical locking mechanism 3
0 is activated and fixes the rod of the pneumatic cylinder 23 in the intermediate stop position. For this reason, Stopparol 11
stops in the middle of retracting, and the take-up roll 01 is rotated between the roll 03 and the stopper roll 11 as shown in Fig. 3.
Point supported. In this state, the reduction motor 06 is driven to rotate the roll 03 via the sprockets 20, 21 and the chain 07, thereby rotating the take-up roll 01.

When the take-up roll 01 rotates by the required amount, the deceleration motor 06 is stopped to stop the take-up roll 01. Next, the take-up roll 01 is secured with tape.
When the tape fixing is completed, the electromagnetic switching valve 34 is switched so that port PA is connected. For this purpose, compressed air is sent to the mechanical locking mechanism 30, and the rod of the pneumatic cylinder 23 is unlocked.

The supply of compressed air to the pneumatic cylinder 23 maintains the state before the mechanical locking mechanism 30 is activated.
By releasing the mechanical locking mechanism 30, the cylinder 23
The rod is slowly extruded and the stopper roll 1
1 slowly retreats and places the take-up roll 01 on the conveyor 10 without impact. Furthermore, cylinder 2
Rod No. 3 is extruded and stops at the rod end. The take-up roll 01 drives the conveyor 10,
The roll is carried in a direction perpendicular to the paper flow direction of the winder.

Next, when there is no take-up roll 01 on the conveyor 10, the electromagnetic switching valve 37 is switched so that port P-A is connected, and compressed air is sent to the cylinder head side of the pneumatic cylinder 23, pushing the stopper roll 11 forward. put out. The stopper roll 11 is a pneumatic cylinder 2
It stops at the rod retraction limit of 3 and prepares for the transfer of the next take-up roll. This completes the series of operations. In addition,
In the above description, the description of the control system was omitted except for one part. It is easy to use normal control technology to detect the movement of each device using limit switches, proximity switches, photoelectric switches, etc., and process the signals with a programmable controller to start and stop each device in sequence. This is because it can be achieved.

Since the present invention is structured as described in detail above, the conventional cushion roll for rotating the roll and the roll extrusion roll are not required, and the apparatus becomes inexpensive. Also, the device is more compact,
This has the advantage of requiring less installation space.
