SCHMIDT waeezcllgmwww ATTORNEYS CONTINUOUS WEB HANDLING AND WINDING APPARATUS I This invention relates to an apparatus for handling and winding a continuous web and more particularly to an apparatus for selectively feeding, guiding, starting and winding a continuous web at a plurality of winding stations.

In the winding of a continuous web such as fabric or the like, it is conventional practice to wind predetermined lengths of the web on successive mandrels or beams with the web being transversely severed between winding on successive mandrels.

Many apparatus heretofore been provided for the purpose of such winding. Typically, these winding apparatus include a single winding station which requires that the winding be discontinued during severing of the web to create a new leading end thereof, removal of the full mandrel, positioning an empty mandrel in the winding station, and starting the winding of the newly created leading end of the web around the empty mandrel. In addition, it has been common practice for most, if not all, of these steps to be carried out manually which in addition to limiting the production of the winding apparatus is costly and time consuming, in starting the newly created leading end of the web around an empty mandrel.

Other apparatus have been provided which include a plurality of winding stations to which the web may be selectively fed for the winding of the web on mandrels positioned therein. However, many of these apparatus, while allowing web to be wound at one of the winding stations while a full mandrel is being removed from the other winding station, have not alleviated manual starting of the web around an empty mandrel.

On the other hand, many web-winding apparatus have been devised of both the single and plural winding station type which include means for starting a newly created leading end of the web around an empty mandrel. However, these starting means have not proven to be entirely satisfactory for one or more reasons. In particular, these starting means have not been satisfactory due to the complexity of their structure, their unreliability and, more particularly, the necessity of having separate starting means for each winding station.

Thus, it is an object of this invention to provide an apparatus for handling and winding a continuous web including improved means for guiding a newly created leading end of the web toward a winding station and for starting the winding of the newly created leading end of the web.

Another object of this invention is to provide an apparatus for handling and winding a continuous web having a plurality of winding stations wherein the winding may be selectively transferred from one winding station to another without manual attention by the operator.

It is still another object of this invention to provide an apparatus for handling and winding a continuous web at a plurality of winding stations and including guide means and starting means for selectively guiding and starting a newly created leading end of the web around the selected one of the mandrels for the winding of the web thereon.

By this invention, the above objects are accomplished by providing an apparatus for selectively feeding, guiding, starting and winding a continuous web at a plurality of winding stations wherein the apparatus comprises means for selectively feeding the web along a longitudinal path of travel, means disposed adjacent the path of travel for severing the web to create a new leading end of the web, at least a pair of spaceapart mandrels for receiving and winding of the web thereon and defining winding stations, guide means operatively as sociated with the severing means and the mandrels and being movable relative to the mandrels between selective positions for selectively guiding the newly created leading end of the web from the severing means toward a selected one of the mandrels, and starting means operatively connected to the guide means and being responsive to movement thereof between the selective positions for positioning itself to direct and start the newly created leading end of the web around the selected one of the mandrels for winding of the web thereon.

In .the preferred embodiment of the apparatus, the guide means comprises an elongate guide arm pivotally mounted at one end thereof adjacent the severing means in the longitudinal path of travel of the web and being selectively pivotal to one position for guiding a newly created leading end of the web from the severing means toward one of the mandrels and being selectively pivotal to another position for guiding another newly created leading end of the web from the severing means toward another of the mandrels and means for pivoting the guide arm between the selective positions. The starting means preferably comprises an elongate conveyor means carried at one end thereof by the end of the guide arm remote from the severing means and being contractable in response to movement of the guide arm between the selected positions around the selected one of the mandrels for receiving the newly created leading end of the web from the guide arm and directing it between the conveyor means and the selected one mandrel around the selected one mandrel to start the winding of the web therearound.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which:

FIG. 7 is an enlarged elevational view similar to that of FIG. 6 without parts being in section and further illustrating the interconnection of the guide means and starting means;

FIG. 8 is an enlarged view of the lower portion of the apparatus of FIG. 6 and illustrating in dotted lines the successive contraction of the starting means about a selected one of the mandrels;

FIG. 9 is an enlarged sectional view taken substantially along the line l0l0 of FIG. 2; and

FIG. 10 is a wiring and pneumatic diagram schematically illustrating means for controlling the operation of the apparatus of FIG. 1.

Referring specifically to FIG. 1, there is schematically illustrated a winding apparatus, generally indicated at 20, constructed in accordance with the present invention for winding a continuous web W at a plurality of winding stations. The winding apparatus 20 includes a pair of spaced-apart

mounting plates

22 and 23 which, as illustrated, may be supported by support members 24 and 25, respectively from the ceiling, not shown, of a building structure and as will be described carry the selective feeding means and severing means of the winding apparatus 20.

A rotatable web guide roll 26 is journaled between

mounting plates

22 and 23. Adjacent guide roll 26 and between

mounting plates

22 and 23, there is mounted the means, generally indicated at 30, for selectively feeding web W along a longitudinal path of travel. The selective feeding means 30 comprises a pair of cooperating

feed rolls

31 and 32. Feed roll 31, preferably, has a smooth and substantially frictionless outer surface so that the web W may slip thereover when the selective feeding means 30 is not feeding the web W and may be formed of steel or the like.

As best illustrated in FIG. 2, feed roll 31 is drivingly connected by a pulley 33 and belt 34 to a drive motor M for driving rotation thereof. With reference to FIG. 10, it will be noted that drive motor M is a three-phase induction motor and has an attenuator 35 and relay switches 36 operatively connected thereto for selectively controlling the actuation thereof for driving of feed roll 31. The other feed roll 32, preferably, has a resilient and a high friction outer surface and, as illustrated in FIG. 2, may be a metal roll coated with rubber or other similar resilient and high friction material.

Feed roll 32 is journaled at opposite ends in

mounting plates

22 and 23 for free rotation and sliding movement relative to

plates

22 and 23 for selective positioning into and out of nipping or feeding relation with feed roll 31. Positioning of feed roll 32 is controlled by pneumatic means such as conventional spring-biased air-operated piston and cylinder assemblies 38 and 39 that are connected by links 40 and 41, respectively, to mounting

plates

22 and 23. As diagrammatically illustrated in FIG. 10, the free ends of pistons 38a and 39a of piston and cylinder assemblies 38 and 39, respectively, are drivingly connected by suitable means, not shown, to opposite ends of feed roll 32 and are normally spring biased in a retracted position to normally maintain feed roll 32 out of nipping or feeding relation with feed roll 31 so that web W may freely pass therebetween. When it is desired to feed the web W by selective feeding means 30, feed roll 32 is positioned by cooperating piston and cylinder assemblies 38 and 39 in nipping or feeding relation with feed roll 31, as shown in FIG. 2, and drive motor M actuated to drive feed roll 31. Thus,

feed rolls

31 and 32 will cooperate to feed the web W therebetween along a longitudinal path of travel.

Immediately beneath and in receiving relation to cooperating

feed rolls

31 and 32 is severing means, generally indicated at 50, for selectively severing the web to create a new leading end thereof. As best illustrated in FIGS. 2 and 9, the severing means 50 comprises normally spaced-apart cooperating

shearing blades

51 and 52 between which the web W passes. Shearing blade 51 is mounted on one side of the longitudinal path of the web W on a stationary bar 53 that extends transversely of web W between

mounting plates

22 and 23. Shearing blade 52 is carried on the other side of the longitudinal path of the web W by an oscillatable shaft 54 that is journaled at opposite ends in

mounting plates

22 and 23. One end of shaft 54 is drivingly connected to the pinion of an air-operated rack and pinion assembly, generally indicated at 55, which when actuated is capable of oscillating shaft 54 to bring shearing blade 52 into shearing relation with shearing blade 51 to transversely sever web W passing therebetween. Shearing blade 52 is preferably, as shown in FIG. 9, mounted in an offset relation to the longitudinal axis of shaft 54 in a longitudinally extending groove therein so that a scissorslike action is obtained by the cooperating

shearing blades

51 and 52 to improve the shearing action thereof.

When the web W is severed by shearing

blades

51 and 52, a new leading end of the web W is created. To facilitate in guiding a newly created leading end of the web W from the

feed rolls

31 and 32 between

shearing blades

51 and 52, an elongate tube 56 is disposed adjacent the path of web W parallel with and between feed roll 31 and shearing blade 52 as best shown in FIG. 2 and has a plurality of longitudinally spaced apertures therein through which air or the like may be selectively forced by means to be hereinafter described to form air jets. The apertures are positioned such that the air jets are directed toward the longitudinal path of the web W to deflect the same toward a guide plate 57 that guides the newly created leading end of the web W between the

shearing blades

51 and 52.

Beyond the cooperating

shearing blades

51 and 52 are a pair of

guide rolls

58 and 59, which are spaced on opposite sides of the path of travel of the web W for further guiding the web W along a longitudinal path of travel and which prevent damage to the web W by the

shearing blades

51 and 52. As noted in FIG. 2, the

guide rolls

58 and 59 are disposed at slightly different elevations with a guide plate 60 cooperating therewith to insure that a newly created leading end of the web W will be fed from the severing means 50 between

guide rolls

58 and 59.

With reference to FIG. 1, a generally rectangular frame 61, adapted to be supported on the floor F of a building structure or the like, is disposed centrally beneath the portion of the apparatus thus far described. At opposite ends 61a and 61b of frame 61 are identical pairs of spaced-apart upright stands 62. Each of the stands 62 having chucking and bearing assemblies 63 of conventional construction mounted thereon with the chucking and bearing assemblies 63 on each pair of stands 62 cooperating for removably and rotatably supporting mandrels 64 and 66, respectively, therebetween. Mandrel drive means in the form of drive motors 67 and 68 are drivingly connected to mandrels 64 and 66, respectively, by suitable means, not shown, for driving rotation thereof. As illustrated in FIG. 10, drive motors 67 and 68 have manual switches 69 and 70 operatively associated therewith, respectively, for controlling the actuation of motors 67 and 68 to drive mandrels 64 and 66.

Mandrels 64 and 66 define opposed, spaced-apart winding stations positioned symmetric with respect to web W passing from between guide rolls 58 and 59 and are equally capable of receiving and winding the web W thereon. Thus, in accordance with the apparatus 20 thus far described, web W may be drawn from a suitable supply source around guide roll 26, through the selective feeding means 30 and severing means 50 between guide rolls 58 and 59 and wound on either of the mandrels 64 and 66.

It is apparent that, when a predetermined amount of web W has been wound on one mandrel, the web W may be severed by severing means 50 and the newly created leading end selectively fed along a longitudinal path of travel by selective feeding means 30. However, means are needed for selectively guiding the newly created leading end of the web W toward the other mandrel and for starting the newly created leading end of the web W around the mandrel for the winding of the web thereon.

Thus, extending upwardly from opposite sides of rectangular frame 61 are pedestals 61 and 72 between which is carried means in accordance with the present invention for selectively guiding a newly created leading end of the web W from between the guide rolls 58 and 59 toward a selected one of the mandrels 64 and 66 and for starting the newly created leading of the web W around the selected one of the mandrels 64 and 66 for the winding of the web W thereon. More particularly, as best shown in FIGS. 2 and 4, cooperating air-operated rack and pinion assemblies are mounted by L-shaped brackets 81 on each of the

pedestals

71 and 72 with the pinions 82 thereof being connected by a main shaft 83 which is oscillatable in opposite directions between first and second selective positions upon selective actuation of the air-operated rack and pinion assemblies 80, the operation of which will hereinafter more fully described.

The guide means of the present invention is generally indicated at and is mounted on main shaft 83 and comprises an elongate guide arm 91, as best shown, in FIG. 2. The guide arm 91 includes suitably spaced-apart sidewalls 91a and 9112 which converge together at one end to form an apex 910. Main shaft 83 is disposed between

sidewalls

91a and 91b adjacent apex 91c and is keyed to guide arm 91 at

opposite sides

91d and 91e thereof to mount the end of guide arm 91 having the apex 91c adjacent severing means 50 in the longitudinal path of a newly created leading end of the web W. Thus, guide arm 91 may be selectively pivoted between first and second positions adjacent mandrels 64 and 66, respectively.

As in FIG. 2, upon pivoting guide arm 91 toward a selected one of the mandrels 64 and 66, the apex 91c thereof will be shifted to one side of the path of the longitudinal web W so that a newly created leading end of the web W will engage one of the

sidewalls

91a and 91b of guide arm 91 and be guided along the contour thereof toward the selected mandrel.

In order to start a newly created leading end of the web W around the selected one of the mandrels 64 and 66, starting means, generally indicated at 100, is operatively connected to guide means 90. The starting means 100 is so constructed and arranged that it is responsive to movement of the guide means 90 toward a selected one of the mandrels 64 and 66 to position itself to direct and start the newly created leading end of the web around the selected mandrel 64 and 66 for the winding of the web W thereon. With reference to FIGS. 1, 5 and 7, the starting means 100 comprises a plurality of elongate endless conveyor-belt-supporting

segments

101, 102, and 103 which are successively interconnected for pivoting movement relative to each other and to the guide arm 91. More particularly, segment 101 is pivotally connected to an extension of the end of guide arm 91 remote from severing means 50 and it to intermediate supporting segment 102. Intermediate segment 102 is in turn pivotally connected to the terminal segment 103.

Conveyor

belt supporting segments

101, 102, and 103 are similar in construction, thus, like parts of each will be designated by like reference numerals. Each

segment

101, 102, and 103 includes a pair of spaced-apart, elongate, supporting links 104 and each supporting link 104 in turn includes spaced apart plates 104a and 10417. The supporting links 104 of each segment are successively interconnected, as shown, in FIG. 4, for pivoting movement relative to each other and to guide arm 91. Pairs of supporting links 104 adjacent their ends are interconnected by cooperating rotatable pulleys 105. An endless conveyor belt 106 is trained around pulleys 105 and is contractable with the pulleys 105 upon pivoting movement of the successively interconnected supporting

segments

101, 102, and 103.

In order to pivot the successively interconnected supporting

segments

101, 102, and 103 to contract conveyor belt 106 around the selected mandrel 64 and 66 to which a newly created leading end of the web W is directed by guide arm 91 as schematically illustrated in FIGS. 1 and 3, drive means is provided which is responsive to movement of the guide arm 91 toward the selected mandrel. In particular, each of the airoperated rack and pinion assemblies 80 have a stationary gear 110, as best shown in FIG. 4, carried thereby concentric of main shaft 83. Follower gears 111 are carried by rotatable shafts 112 at

opposite sides

91d and 916 of guide arm 91 and mesh with stationary gears 110. Upon pivoting movement of guide arm 91, follower gears 111 follow stationary gears 110 to rotate shafts 112. Shafts 112 have eccentric cams 113 mounted thereon for rotation with shaft 112. Circular sprockets 114, FIG. 5, are freely mounted on shafts 112 adjacent cams 113 and have pins 115, respectively, which are engaged by cams 113 upon pivoting of guide arm 91 beyond predetermined limits toward a selected mandrel to rotate sprockets 114.

As best illustrated in FIGS. 4 and 6, separate sprockets I16, 117, and 118 are carried by supporting links 104 between plates 104a and 104b. It will be noted that

sprockets

116 and 117 are smooth. Drive chains 120

interconnect sprockets

114, 116, 1 17 and 118, as best illustrated in FIG. 6. Since

sprockets

116 and 117 are smooth, chain guide rolls 121 are provided in cooperation therewith for conforming the drive chains 120 therearound in frictional engagement with the

sprockets

116 and 117.

Thus, it can be seen that as guide arm 91 is pivoted toward a selected one of the mandrels 64 and 66, drive sprockets 114 will be rotated to drive drive chains 120 and rotate the other

interconnected sprockets

116, 117, and 118 to pivot the supporting

segments

101, 102, and 103 relative to each other and the guide arm 91 to contact the endless conveyor belt 106 around the selected mandrel. With reference to FIG. 8, there is shown in dotted lines the successive stages in the contraction of conveyor belt 106 around mandrel 64 upon movement of the guide arm 91 toward mandrel 64. The full lines represent the position of the conveyor belt 106 just before the pins 115 of drive sprockets 114 are engaged by cams 113 to start rotation of drive sprockets 114 and the drive chains 120 carried thereby. In the illustration of FIG. 8, the drive chain moves in the direction indicated by the arrow 122 to pivot the conveyor

belt supporting segments

101, 102, and 103 in a counterclockwise direction relative to each other and guide arm 91. The relative movement between the various segments and guide arm 91 is determined by the relative sizes of

sprockets

116, 117 and 118 and the friction characteristics thereof with drive chains 120.

As will be apparent, the relative movement should be as schematically illustrated in FIG. 8 so that endless conveyor belt 106 is contracted around the selected mandrel. In order to prevent loosing of the conveyor belt 106 during its contraction around the selected mandrel, the terminal pulley 105 is spring biased by conventional means 125 outwardly and longitudinally of conveyor-belt-supporting segment 103. With conveyor belt 106 tightly entrained around pulleys 105 and contracted around the selected mandrel, the conveyor belt 106 may be driven by the frictional engagement thereof with the selected mandrel. Thus, web W will be received from the guide arm 91 between conveyor belt 106 and the selected mandrel and directed around the selected mandrel for the winding of the web W thereon.

During normal operation of the winding apparatus 20 of the present invention the continuous web W is drawn from some suitable supply source as indicated in FIG. 1 under guide roll 26, over feed roll 31, between feed rolls 31 and 32, through severing means 50 and between guide rolls 58 and 59 to one of the rotatably driven mandrels 64 and 66 on which the web W is wound. Motor M for driving feed roll 31 is idle during this time and feed roll 32 is out of feeding relation with feed roll 31 so that web W is free to slip over feed roll 31.

Referring specifically to FIG. 10, there is schematically illustrated an example of a wiring and pneumatic control diagram for the winding apparatus 20 and from which the operation of the apparatus 20 will be described. Upon the winding of a predetermined amount of web W on a given mandrel, the rotation of that mandrel is discontinued by manually opening the appropriate control switch 69 and 70 to discontinue the winding of web W and its passage through the winding apparatus 20. Attenuator 35 is checked to insure that is adjusted so that feed roll 31 will not be driven by motor M upon the closing of switches 36 and the appropriate switch 69 and 70 closed to drive the other mandrel. Master switches are closed to energize a solenoid-actuated air valve 131 to supply air from a compressed air source 132 through tube 56 to establish air jets against the web W and to energize a time delay relay 133. Immediately thereafter, mandrel selective switch 134 is positioned to energize a double-acting solenoidactuated air valve 135 to supply air from a compressed air source 136 to the proper side of the air-operated rack and pinion assemblies 80 to cause guide arm 91 to pivot from its normally inactive position to an active position adjacent the selected mandrel. During movement of the guide arm 91, the converyor-belt-supporting

segments

101, 102, and 103 will be pivoted relative to each other and the guide arm 91 to contract the conveyor belt 106 around the selected mandrel. The frictional engagement of conveyor belt 106 with the mandrel drives the conveyor belt 106 in synchronism with the mandrel.

After positioning mandrel selective switch 134, normally open spring-biased switch 137 is closed to energize relay switches 139 and 140. The closing of relay 139 establishes a holding circuit for relay 138 while the closing of relay switch 140 energizes a solenoid-actuated air valve 141. Actuation of valve 141 causes air to be supplied from compressed air source 132 to air-operated piston and cylinder assemblies 38 and 39 to move feed roll 32 into nipping or feeding relation with feed roll 31. Simultaneously with the supply of air to piston and cylinder assemblies 38 and 39, air is supplied to normally open pneumatic switch 142 to close the same and energize relay 143 and close relay switches 36, previously described. Since the attenuator 35 is set so that the closing of relay switches 36 does not actuate motor M to drive feed roll 31, the web W will be nipped between feed rolls 31 and 32.

Normally open, severing switch 145 is now closed to energize solenoid-actuated air valve 146 to supply air from compressed air source 132 to rack and pinion assembly 55 to oscillate shaft 54 and bring shearing blade 52 into cooperation relation with shearing blade 51 to transversely sever the web W and create a new leading end of the web W.

Severing switch 145 is opened to return shaft 54 to its normal position. The attenuator 35 is now adjusted to feed the web W along a longitudinal path of travel. As the web W is fed, the newly created leading end of the web W is guided by the air jets from tube 56 and guide plate 57 between

shearing blades

51 and 52 and guide rolls 58 and 59. From the guide rolls 58 and 59 the newly created leading end of the web W is guided by guide arm 91 toward the selected mandrel and is received by conveyor belt 106 of starting means 100 and directed between the conveyor belt 106 and the selected mandrel to start the winding of the web W thereon.

After time delay relay 133 times out, normally closed relay switch 148 opens to deenergize double-acting solenoid-actuated air valve 135 so that air will be exhausted from rack and pinion assemblies 80. The weight of the guide means 90 and starting means 50 then cause the same return their normally inactive position. As will be apparent, it will be necessary to manually reset switches 130 and 134 for the next operation of the apparatus 20. Preferably, these switches are reset immediately so that feed roll 32 will be moved out of nipping relation with feed roll 31 and drive motor M deenergized and the winding to the other mandrel.
