For the purpose this specification, winding station (W) is that be provided with take-up roll and the take-up roll of rewinding machine work Point.

Winding station (W) in be provided with third take-up roll (R3), relative to paper web (3) from the direction (F3), institute It states third take-up roll (R3) and is arranged on downstream relative to the first two take-up roll (R1, R2).In addition, second winding roller (R2) is opposite It is arranged in the height lower than the first roller (R1) in the pedestal of equipment.In the embodiments shown in the drawings, the first roller (R1) and The position of the axis of second roller (R2) is fixed.Third roller (R3) is located at the top of the second roller (R2) and has corresponding axis To end (S3, S30), the axial end portion (S3, S30) is connected to the actuator (A3) as further shown in following, the cause Dynamic device (A3) allows the third roller (R3) to be moved to the second roller (R2) and move from the second roller (R2), that is, such as following into one Step description, allow third roller (R3) mobile from above-mentioned pressure area (N) movement and towards above-mentioned pressure area (N).With reference to institute in attached drawing The embodiment shown, actuator (A3) is revolving actuator.

Four-roller (R4) is set in winding station (W).

The axis of the roller (R1, R2, R3, R4) is parallel to each other.

In an end (S30) of third roller (R3), such as with reference to the right hand end of Fig. 5, corresponding toothed wheel (RS30) Be bonded with intermediate toothed wheel (RF), the toothed wheel (RF) in centre again with by corresponding motor (M) drive with tooth Driving wheel (RM) engagement.It in this way, is that third roller (R3) provides power, thus the motor control by motor (M) The third roller (R3) is made around the rotation of corresponding axis (X3).It is provided on another end (S3) of third roller (R3) The wheel (RS3) of tooth, the toothed wheel (RS3) is by intermediate toothed wheel (RFD) and key in an end of four-roller (R4) (S4) toothed wheel (RS4) engagement on.With reference to Fig. 5, left end (S4) of toothed wheel (RS4) key in four-roller (R4) On.Therefore, motor (M) also controls the rotation that four-roller (R4) surrounds corresponding axis (X4).In other words, motor (M) Determine that third roller (R3) surrounds rotation of its own axis (X3) by means of transmission device (RM, RF, RS30), then roller (R3) is again Determine that four-roller (R4) surrounds the rotation of its own axis (X4) by transmission device (RS3, RFD, RS4).In fact, third roller (R3) it constitutes and is transmitted to the element of four-roller (R4) for that will move from motor (M).

Third roller (R3) is supported by right arm (B30) and left arm (B3).Specifically, right arm (B30) is box shaped and wraps Containing transmission gear (RM, RF, RS30).It is caused in addition, right arm (B30) is connected to rotation by corresponding hinge bar (M30) and (T30) Dynamic device (A3).Right arm (B3) is the arm in hook-type and is hinged on fixed pin (P3) that the fixed pin (P3) is limited to The fixation wall (FW) of rewinding machine (RW).Pin (P3) axis be axis that is horizontal and being parallel to roller (R3, R4) (X3, X4).Moreover, as shown in figs. 5 a and 6, selling the axis of the axis of (P3) and the output shaft across bushing (300) of motor (M) It is overlapped, the bushing (300) the is inserted in rewinding machine opposite with side wall (FW) of rewinding machine that pin (P3) is inserted into Side wall (FW) in.Right arm (B3) is connected to actuator (A3) by two hinge bars (M3, T3), one of hinge bar (M3) It applies on the bar (C3) activated by actuator (A3).

In this way, as described further below, roller (R3) can be relative to the instantaneous diameter for being formed by paper roll It is arranged at the position of more or less separate core (4).In other words, actuator (A3) control third roller (R3) is around pin (P3) The rotation of axis, and third roller and four-roller can surround respective axis (X3, X4) rotation under the control of motor (M) Turn.

According to the present invention, by completing paper roll for four-roller (R4) is with first three roller (R1, R2, R3) associated, so that Final stage of the rolling of paper on core is related to using all four rollers (R1, R2, R3, R4)), at this stage, own Four rollers are around paper roll and limit the space with variable volume, and the formation of the paper roll is completed in the space.

In other words, according to the present invention, the diameter of the paper roll formed in station (W) is lower than predetermined value (for example, 90mm) phase Between, four-roller (R4) is all in off-position；And when reaching the predetermined value, the four-roller (R4) is in operation winding Position, to help that paper web (3) is wound up on core (4) using other three rollers (R1, R2, R3), until reaching paper roll Final diameter (for example, 140 millimeters).In off-position, four-roller (R4) is spaced apart with the paper roll formed, and is being operated Winding position, the four-roller (R4) contact with paper roll (L).

Four-roller (R4) is connected to corresponding positioning actuator (A4), and the positioning actuator (A4) allows four-roller (R4) It is respectively placed in position (A) and operation winding position (B) of raised NOR operation as described further below.Four-roller (R4) reduced position (B) is position of the four-roller (R4) in the completion stage of paper roll.

With reference to embodiment shown in the drawings, four-roller (R4) answers the right arm (B40) of right end (S40) by means of support phase The left arm (B4) of left end (S4) is answered with support phase and is connected to corresponding positioning actuator (A4).On each arm in the arm It is equipped with hinge bar (M40, T40；M4, T4) transmission device, have hinge bar (M40, T40；M4, T4) transmission device Connect the arm to the horizon bar (C4) operated by actuator (A4).The arm (B40, B4) is on the axis (X3) of third roller Hingedly.Therefore, rotation of actuator (A4) control four-roller (R4) around the axis (X3) of third roller (R3).Left arm (B4) has Box shaped structure and include transmission gear (RS3, RFD, RS4).

Therefore, said mechanism allows following movement:

A) third roller (R3) surrounds the rotation of its axis (X3)；

B) four-roller (R4) surrounds the rotation of its axis (X4)；

C) rotation of the third roller (R3) around the axis of pin (P3)；

D) rotation of the four-roller (R4) around the axis (X3) of third roller (R3).

Specifically, rotation c) corresponds to the movement of third roller (R3) from pressure area (N) and the movement towards pressure area (N), is related to The rotation d) of four-roller (R4) is also similar.

As described further below, once completing the winding to paper roll in station (W), four-roller (R4) is moved back to Initial raised position (A) is to discharge the paper roll (L1) completed.

This four take-up rolls (R1, R2, R3, R4) are only assisting paper web (3) wound in the completion stage on core (4) each other Make.In the initial stage of winding, i.e., during the diameter of the paper roll of formation is less than predetermined value, be used only first three roller (R1, R2, R3), and these rollers realize the initial stage wound according to scheme known per se.Completion stage of the four-roller (R4) in paper roll Intervention multiple advantages have been determined.In fact, the four-roller (R4) plays the role of pressure roller, the four-roller is last Last sheet material of paper roll is pressed on that sheet material below last sheet material by winding portion, therefore even if is used Less amount of glue, also due to the pressure that thus applies and facilitate the gluing of part to hang down.Meanwhile four-roller (R4) has Help be kept accurately at paper roll (L) in winding station (W).In fact, although first three roller (R1, R2, R3) is relative to core (4) Substantially asymmetrically it is arranged, but positioning of the four-roller (R4) in reduced position (operation winding position " B ") helps In the space that the paper roll (L) that limit is being formed ideally is included, to almost eliminate the negative shadow of the oscillation of the paper roll It rings, caused by the oscillation is often as the structure of the winding speed executed and paper roll.In addition, the formation when paper roll is completed simultaneously And four-roller (R4) back to initial raised position (A) when, the paper roll of completion can be by previously by the four-roller (R4) side occupied is removed from winding station (W), to allow to start new circulation.

According to another aspect of the present invention, when the rewinding using the deceleration system for being provided with paper roll in winding station downstream (W) When with machine, four-roller (R4) is conducive to paper roll and enters in the deceleration system.

For example, the deceleration system includes multiple reduction rolls known per se with reference to Fig. 2A-Fig. 2 H and Fig. 3 A- Fig. 3 H (D1,D2,D3).In fact, reduction roll (D1, D2, D3) is winding the defeated of the paper roll (ER) in station downstream (W) along setting is parallel to The direction positioning of plane out.Each reduction roll in reduction roll (D1, D2, D3) is revolved around its own axis with scheduled angular speed Turn.Therefore, because roller (D1, D2, D3) and the contact between the paper roll (LI) that output plane (ER) leaves, along output plane (ER) control of the paper roll speed by roller (D1, D2, D3), to prevent paper roll (LI) from using in an uncontrolled fashion from rewinding It is come out in machine.

With reference to the rewinding machine of the deceleration system equipped with such paper roll, four-roller (R4) --- in four-roller In the movement of repositioning in raised position (A) --- it can make with the paper roll (LI) completed towards the output Obtain part of the part rather than just reel system that four-roller is also deceleration system.

It is described below and is related to the possible example of two operated with of reel system according to the present invention.

The first example will be described with reference to Fig. 2A-Fig. 2 H.

The stage shown in Fig. 2A, wherein paper roll (L) is in the completion stage, and core (4) has been located at roller (R1) upstream position between roller (R2), all four rollers (R1, R2, R3, R4) are all contacted with paper roll (L).At this stage, Roller (R3) and roller (R4) are in winding position.Particularly, roller (R4) is reduced to operation winding position (B).In fig. 2b, paper roll is complete At roller (R3) and roller (R4) are in previously mentioned position, and roller (R4) continues to rotate, to apply on the paper roll of completion (LI) Plus-pressure, the pressure assist and promote the gluing of part to hang down.In follow-up phase shown in fig. 2 C, when roller (R4) is increased When, roller (R3) is maintained at position and the acceleration of previous stage, so that the paper roll (LI) completed be made to be detached from simultaneously from the first roller (R1) It is pushed to four-roller (R4).Meanwhile the core (4) for forming next paper roll being proceeded between roller (R1) and roller (R2) on it. In the stage shown in fig. 2 C, the paper roll (LI) of completion is briefly contacted with roller (R2) and roller (R3).(figure in the next step 2D), when four-roller (R4) further increases, third roller (R3) is reduced and the paper roll (L1) completed is further away from winding It stands.In the follow-up phase shown in Fig. 2 E, third roller (R3) is further decreased, and four-roller (R4) continues to increase until four-roller reaches To maximum raised position (A), the paper roll being completed at the same time (LI) continues far from the movement of winding station.Then (Fig. 2 F), when third roller (R3) towards when the point of arrival decline of new core (4), four-roller (R4) reduces and pushes the paper roll of completion (L1) to first deceleration Roller (D1).At this stage, four-roller (R4) helps that the paper roll (L1) completed is discharged from winding station.In next stage (figure 2G), when further decline third roller (R3) determines it and the new paper roll (L) for the paper roll being previously completed is replaced to contact, into one Step reduces four-roller (R4) and determines that the paper roll (LI) completed finally is transported to reduction roll (D1, D2, D3).The stage shown in Fig. 2 H In, paper roll (L) has reached predetermined diameter (for example, 90mm), and reduces four-roller (R4) again to operation winding position (B). In this stage, all four rollers (R1, R2, R3, R4) are all contacted with the paper roll (L) continuously formed, until completing the shape of paper roll At.

The second example will be described with reference to Fig. 3 A- Fig. 3 H.
