The present invention relates to improvements in winding machines and particularly to machines ior winding paper on one or a plurality of rolls as it comes from a previous stage in a paper making or handling process.
Paper as it is usually produced is provided with what may be termed a right side and a wrong side and it is generally desirable in the use of the paper to handle it in such a way that the right side will present itself for use or further processing. An object of the present invention has been to provide a winding machine which is capable of causing paper to be wound alternatively on one or a plurality of rolls and in such a way as to effect a reversal of the paper as it is received from a preceding operation in the paper making or handling process.
An important feature of the invention is the pro ision of improved devices for the feeding and guiding of the paper through the machine. The arrangement is such that the paper is fed uniformly and positively at various points so as to avoid any tendency toward wrinkling and it is automatically guided into the proper channels by both fixed and adjustable devices.
Numerous other features and advantages of the invention will appear from the detailed description of one admirable, illustrative form of the same which will now be given in conjunction with the accompanying drawings in which:
Figure 1 is a side view of a paper winding mechanism embodying the invention, and
Figure 2 is a plan view of the same.
The apparatus shown in the drawings is designed to receive a paper web 5 from a preceding stage in the production or handling of the paper, as from a slitting mechanism 6, and to wind the same onto two or more rolls such as '7 and 8 or alternatively to wind the whole width into one roll in either position.
As shown the roll 7 is formed by the winding rolls 9, 10 which are suitably driven in a way to be explained, and to which the paper is led from the slitting machine 6 beneath a plurality of conveyor belts 13 arranged side by side but spaced laterally and carried by idle guide rolls or pulleys 14 and 15 and above a plurality of similar cooperating conveyor belts 17 carried on rolls or pulleys 18 and 19. While all of the rolls 14, 15, 18 and 19 may extend completely across the width of paper handled by the machine, if desired, it is preferable to employ separate pulleys at spaced intervals for at least one support for each of the tapes so as to maintain the proper spacing of the tapes. One of the guide rolls or pulleys 14 and 15 is preferably adjustable transversely of its axis to maintain the conveyor belts thereon in relativelytaut condition. Similarly the guide roll or series of pulleys 18 is preferably adjustable to permit tensioning of the belts 17.
The conveyor belts 1'7 may be suitably driven as by means of a belt or chain 20 driving the roll 19 from the winding roll 12. In order to insure driving of the belts 17 at the same speed as the paper is fed and wound onto the rolls 5 7 and 8 provision may be made to permit clutching and unclutching of the roll 19 to the driving chain at will. For this purpose a clutch 200 adapted to be controlled by a foot pedal or a lever 201 may be provided. When the machine is first 70- placed in operation the clutch may be shifted to cause the roll 19 to be driven from the roll 12,0r other suitable source until the paper has been properly started on the core. The clutch may then be thrown out of engagement and the driving of the tapes may be effected by the frictional engagement of the paper and will then be at precisely the speed required. This method of operation will be found to completely eliminate difiiculties in the way of wrinkling of the paper due to theuneven feeding of same. It will not be necessary at any time to positively drive either of the rolls 14, 15 carrying the conveyor belts 13 but these'conveyor belts may be frictionally driven from the start by the conveyor belts 17 35 through contact with the paper web. Subsequently, when the clutch 200 is disengaged, the engagement of the paper between the upper and lower conveyor belts provides the desired traction for effectively driving both series of belts at the rate at which the paper is being wound.
The roll 8 is driven by the Winding rolls 11 and 12 which are similar to the rolls 9 and 10. From between the conveyor belts the paper may pass around the roll 14 and thence around the winding roll 10 and onto the roll? to be wound. For the purpose of providing a long are of contact about the roll 10 so as to secure adequate traction on the paper the roll 14 is preferably located substantially directly below the roll 10. This results in an arc of contact of the paper around the surface of the roll 10 for about 160 or more. Alternatively one or more of the paper strips pro duced by the slitting machine "6 may be carried forward on the conveyor belts 1'7 and beneath a fixed guide 23 around a guide roll 24 and around the winding roll 12 and onto the roll 8 to be wound thereon. Location of the roll 24 substantially directly under the roll 12, as shown, pro- 119 vides for a long arc of contact with the latter and insures proper traction.
It will be observed that the paper, as it is wound on either or both of the rolls 7 and 8 will have its relation reversed. Thus the surface which is uppermost as the paper leaves the slitting machine 6 will be faced inwardly as the paper is wound upon the rolls 7 and 8. This, as already explained, serves to present the right side of the paper in the way desired in the further processing of the same.
While the provisions of the upper series of belts 13 in conjunction with the lower series 1'7 serves to effectively confine and guide the paper, particularly as it is first threaded through the machine, these belts are not essential and they may, if desired, be dispensed with. The guiding function and the frictional engagement of the paper will then be effected through the cooperation of the rolls 14 and 15 and the belts 1'7. It is to be noted that the roll 15 is placed quite close to the roll 18 and has its axis on nearly the same horizontal plane as that of the roll 18. This serves to provide a comparatively large arc of contact between the roll or pulleys 15 and the surface of the paper or the belts 13.
In order to facilitate the division of the paper and the guiding of the various sections thereof onto the desired rolls adjustable guides are provided. These are pivoted at 26 and have operating levers or pedals 27 extending to the right in Figure 1 to within reach of an operator or attendant at this end of the machine or if desired suitable operating connections may extend to the side of the machine. These guides may be moved to the operative position shown in full lines in Figure 1 or dropped to inoperative position as shown in dotted lines. They may be held in either position by any suitable form of detents such as set screws or the like. There are several of these guides arranged across the width of the machine and between the conveyor belts 17. In operation selected guides are elevated to the position indicated in full lines in Figure 1 to guide selected strips of the paper web upwardly around the roll 14. Beyond the movable guides 25 are found a set of fixed guides 30 and a second set of fixed guides 31 to guide the paper to and around the winding roll 10. The remaining strips of the paper web 5 are carried forward on the conveyor belts 17 over the corresponding guides 25, which for this purpose are dropped to the position shown in dotted lines in Figure 1, beneath the fixed guide 23 and around the guide roil 24 to the winding drum 12. Guides 21 and 22 may be provided for suitably guiding these strips. Both of these guides may be fixed if desired although it is regarded as preferable to pivotally mount the guide 21 upon a rod 210 and provide either 1 the rod or the guide with a downwardly extending arm 211 which is accessible from the side of the machine. By the proper adjustment of this arm the guide 21 which extends upwardly between the various belts 17 may be shifted into T either the dotted or full line position shown.
side of the machine.
The winding rolls 9, 10, 11 and 12 may be driven in any usual or suitable manner as for example by means of separate electric motors such as indicated at 33, 34, 35, 36 in Figure 2 or they may be driven through suitable gearing from a common motor. As previously explained the roll 19 which at times serves to drive the belts 17 may be driven through the chain 20 from the motor 38 which drives the roll 12. However, if desired, a separate motor may be employed to drive the roll 19 so that a substantially equal load may be applied to the motors which drive the feed rolls.
While the machine disclosed herein is primarily intended for driving of the winding rolls 9, l0, l1 and 12 in the direction indicated by the arrows this direction might be reversed, if occasion required it, by merely reversing the direction of rotation of part or all of the driving motors, 33, 34, 35 and 36 and making other minor changes. In this event the paper would be wound upon the rolls '7 and 8 in opposite sense and the reverse side would be outermost. One pair of rolls 9 and 10 or 11 and 12 might, if desired, be reversed independently of the others so as to reverse only a part of the paper. Besides reversing the motors it would merely be necessary to swing the guide members 37 and 38 (Figure 1) about their pivots until their lower ends are adjacent the rolls 10 and 12. This will cause the paper to be directed around the rolls 9 and 11 and onto the right hand side of the rolls '7 and 8. The members 37 and 38 may suitably each comprise downwardly extending arms having a continuous bar carried at their lower ends and extending across the width of the machine.
In order to permit a quick stopping of the winding drums or rolls 9, 10, 11 and 12 whenever the necessity arises and also enable stopping of the paper rolls in any desired position so that the severed ends of a strip may be joined together suitable braking devices may be provided. For example in the drawings these devices have been conventionally shown as including a brake drum 40 secured to the axis of each of the rolls while a series of arms il may be adapted to be brought into cooperation with these drums upon operation of a foot pedal 42.
It will be understood that many variations in the particular structure described and shown can be made without departing from the spirit of the invention as defined in the claims. The expressions and terms used hereinabove have been employed for purposes of description merely and are not to be regarded as imposing any limitations on the invention.
