Abstract
Description
Technical Field
[0001] The present invention relates to a web winding and conveying system for a web processing system.
Background Art
[0002] Cross-reference to related applications This application is a PCT application of U.S. Provisional Application No. 63 / 467614, filed on May 19, 2023, claims the priority thereof, and the entire disclosure thereof is incorporated herein by reference.
[0003] Polymer films are manufactured by melting polymer pellets in an extrusion device and extruding the molten polymer from the gaps of a die (e.g., die slot, die lip) communicating with the extrusion device. The molten polymer film is extruded from the die in the form of a web or a tube. The web is cooled and processed by a cooling drum to form a single-layer web. The tube is processed by a blow film device and discharged in the form of a flattened two-layer web. The web is further processed through a configuration of rollers to impart desired physical properties to the web. The web is discharged from the configuration of rollers to a downstream winding system such as a turret winder, where the web is wound around a core.
[0004] Problems can occur when operating these systems. There is a risk that winding or other processing may be interrupted and / or problems with web quality or other malfunctions within the process may occur. In some cases, it is necessary to interrupt winding or other processing to correct or eliminate these problems (web quality defects, trim losses, poor roll change at the spindle, etc.). These require a slowdown in upstream processing or a shutdown of the machine. By the operator intervening to correct such scenarios, the operator may be placed in a dangerous area. By slowing down or stopping the full operation of the machine line, there is a risk of incurring time and material costs, especially during startup operations to return the line to its normal operating state.
[0005] Therefore, an improved system is needed to address the above problems. [Overview of the project]
[0006] In embodiments described herein, a roll transport assembly for a web processing system is disclosed, the assembly including a support beam movably mounted to the frame of the web processing system (for example, mounted to move vertically, horizontally, or a combination thereof).

[0028] As shown in Figure 4A, a web processing system according to one embodiment of the present disclosure (e.g., a web transport and winding system) is collectively indicated by the number 100. The web transport and winding system 100 includes a linear accumulator 10 positioned to receive a web W from an upstream part (not shown) of a machine, including a web processing system such as a blow film processing system in which a two-layer web is produced, or other types of systems in which a single-layer web is produced. The web W shown in Figures 4A to 10B, 12A, 12B, and 13 is a two-layer web, as shown in detail in Figure 4B. The web transport and winding system 100 is configured to process the two-layer web W by including a duplicate component, as described herein. The web transport and winding system 100 includes a plurality of guide rollers, 80A, 80B, 80C, 80D, 80E, 80F, and 80K, which guide the web W through the web transport and winding system 100. Guide rolls 80A, 80C, 80D, 80E, 80F, and 80K are uniformly cylindrical in shape. Guide roll 80K is a widening roll having a uniform cross-sectional diameter throughout its width, but is formed in a curved or arched shape used to generate a widening effect while directing the web toward the opposite end of the roll. Both the amount of curvature and the direction of rotation can be adjusted to increase or decrease the amount of widening effect across guide roll 80K. However, this disclosure is not limited in this respect, as other types of widening rolls can be employed, i.e., those having a non-uniform shape, i.e., an inverted crown shape where the thickness gradually decreases toward both ends of the guide roll (i.e., the outer diameter decreases) and the central part is thicker (i.e., the outer diameter increases). Guide rolls 80C and 80D form a nip into which the web W is drawn, with the assistance of guide roll 80C, which is a driven pull roll. Guide rolls 80E and 80F are operational during the web transport process and selectively form a leader nip, with the assistance of guide roll 80E pulling the web W into it. Guide roll 80E is a driven pull roll mounted on an axis that is fixed in place relative to the frame 100F and therefore does not have linear movement.Guide rolls 80E and 80F are shown spaced apart from each other in a standby position in Figure 5B. Guide roll 80F is movable toward guide roll 80E and toward each other (e.g., lateral translation relative to frame 100F) to form a nip (as shown in Figures 6, 7A, 8A, 8F, 9B1, 12A, 12B, 13), for example as shown in Figure 5B. Guide rolls 80E and 80F are perpendicularly close to the belt-type auxiliary conveyor assembly 60, as will be further described herein. As shown in Figures 8C1, 8C2, 8G, 8H, 8I, 12A, and 12B, the web conveying and winding system 100 includes two edge trim slitters 70 assembled in close proximity to the web W and positioned between idler rolls 80A and 80B. The edge trim slitter 70 is movably mounted on a linear rail 70R fixed to a beam 70B, which is fixed to a frame 100F. The edge trim slitter 70 includes a linear bearing 70L that moves along the linear rail 70R. Each edge slitter 70 includes a belt clamp 70C that engages with a drive belt 70BB. The drive belt 70BB is wrapped around a drive sprocket 70X, which is mounted on a gearbox 70Y. A motor 70M is drive-engaged with the gearbox 70Y and is fixed to the beam 70B via a mounting bracket 70G. Each edge slitter 70 includes a retractable and extendable cutting knife 70Z, with the cutting knife 70Z shown in the extended position, as shown in Figure 8I. Figure 8H shows the edge slitter 70 with the cutting knife retracted. The edge slitter 70 is transversely translatable across the web W from both ends (see Figures 12A and 12B) to the center position in order to form a narrow web strip WN by cutting, as shown in Figures 8C1 and 8C2 and annotated by arrow LL.
[0029] The web conveying and winding system 100 includes a conveying section 90, which includes several additional rollers that cooperate to convey the web W to a downstream winding system such as the dual turret winding system 200 shown in Figures 1 to 3. The dual turret winding system 200 includes a finished product roll cart 201, an overhead gantry 202 for finished product rolls, a winding machine core shaft 203, a winding machine web guide bar 204, a winding machine roll change carriage 205, a winding machine roll change lead-in roll 206, an electrostatic neutralizing bar 207, a winding machine lead-in roll including a separator nip 208, and an edge trim slitter 70.
[0030] Referring again to Figure 4A, the web transport and winding system 100 includes a roll transport assembly 20 that is movable (e.g., translational, vertical, and tilting) relative to a frame 100F (e.g., a fixed frame) to which the web transport and winding system 100 is assembled. As further described herein, the roll transport assembly 20 is movable from a storage position (e.g., Figure 4A) to a transport position (e.g., Figures 8A, 8B, 8D, 8E, and 8F) while the web is being transported again through the web transport and winding system 100. In this position, a portion of the roll transport assembly 20 unfolds to assist in transporting the web W to the leader. As will be further described herein, the roll conveying assembly 20 cooperates with the belt-type auxiliary conveyor assembly 60 to facilitate the attachment (e.g., adhesion) of a pair of narrow web strips WN of the two-layer web W (see Figures 8C1 and 8C2) to the upper leader strip 52U and the lower leader strip 52L.
[0031] The web transport and winding system 100 includes an upper leader supply system 50U and a lower leader supply system 50L. The upper leader system 50U includes an upper leader supply spindle roll 51U, which is rotatably mounted on a frame 100F and on which the supply section of the upper leader strip 52U (e.g., polymer web of film) is wound. The lower leader system 50L includes a lower leader supply spindle roll 51L, which is rotatably mounted on a frame 100F and on which the supply section of the lower leader strip 52L (e.g., polymer web of film) is wound. Although the web transport and winding system 100 is illustrated and described as including an "upper" leader supply system 50U and a "lower" leader supply system 50L, the present invention is not limited in this respect, as other relative positions of the leader supply systems 50U and 50L may be adopted, including, but not limited to, the left-side and right-side leader supply systems of the two leader supply systems being positioned along substantially the same horizontal line.
[0032] The upper leader system 50U includes an upper adhesive application system 54U located downstream of the upper leader spindle roll 51U. The upper adhesive application system 54U is configured to apply an adhesive, such as double-sided tape, to the upper leader strip 52U. An idler roll 55U is located opposite the upper adhesive application system 54U to prevent the upper leader strip 52U from flexing during adhesive application. An upper leader slitter 56U is located downstream of the upper adhesive application system 54U and is configured to cut the upper leader strip 52U laterally, thereby separating it from the upper leader spindle roll 51U. Another idler roll 57U is located downstream of the upper leader slitter 56U and is configured to guide the upper leader strip 52U beyond the idler roll 57U toward the leader dip formed by idler rolls 80E and 80F.
[0033] The lower leader system 50L includes a lower adhesive application system 54L located downstream of the lower leader spindle roll 51L. The lower adhesive application system 54L is configured to apply an adhesive, such as double-sided tape, to the lower leader strip 52L. An idler roll 55L is located opposite the lower adhesive application system 54L to prevent the lower leader strip 52L from flexing during adhesive application. A lower leader slitter 56L is located downstream of the lower adhesive application system 54L and is configured to cut the lower leader strip 52L laterally, thereby separating it from the lower leader spindle roll 51L. Another idler roll 57L is located downstream of the lower leader slitter 56L and is configured to guide the lower leader strip 52L beyond the idler roll 57L toward the leader dip formed by idler rolls 80E and 80F.
[0034] As shown in Figure 12B, idler rolls 57U and 57L, and the upper leader strip 52U and lower leader strip 52L, each have a width W57. Idler rolls 80E and 80F each have a width W80 that is approximately equal to the width W57. Although idler rolls 80E and 80F are illustrated and described as each having a width W80 that is approximately equal to the width W57, the present invention is not limited in this respect, as idler rolls 80E and 80F may have a larger width, approximately equal to the overall width of the divided roll 24, as shown in Figure 12A. As shown in Figure 8C2, the narrow web strip WN has a width WWN that is smaller than the total width WF of the web W, and slightly larger than the width W57 of idler rolls 57U and 57L, and the upper leader strip 52U and lower leader strip 52L. The first continuous conveyor belt 60B and the second continuous conveyor belt 60B are spaced laterally apart by a width W60, which is slightly larger than the width W57 of the idler rolls 57U and 57L, and the upper leader strip 52U and lower leader strip 52L, and slightly larger than the width W80 of each idler roll 80E and 80F. Because the width WNN of the narrow web strip is slightly larger than the width W57, the first continuous conveyor belt 60B and the second continuous conveyor belt 60B can grasp the narrow web strip WN, and the upper leader strip 52U and lower leader strip 52L can pass between the first continuous conveyor belt 60B and the second continuous conveyor belt 60B and the guide rollers 80E and 80F.
[0035] As shown in Figure 26, each of the upper leader system 50U and the lower leader system 50L includes a support column 100FX fixed to the frame 100F, and an extendable core shaft 51X attached to the support column 100FX. The upper leader spindle roll 51U and the lower leader spindle roll 51L are fixed to the corresponding extendable core shaft 51X. A brake or motor system 51B communicates with one of the corresponding extendable core shafts 51X to generate tension in the upper leader strip 52U and the lower leader strip 52L. The upper leader strip 52U and the lower leader strip 52L are wound around the corresponding upper leader spindle roll 51U and the lower leader spindle roll 51L, housed on them, and discharged from there. The upper leader slitter 56U and the lower leader slitter 56L are installed between the corresponding idler rolls 57U, 57L and the guide roll 58. The assembly frame 100F1 is fixed to the frame 100F and supports the idler rolls 57U, 57L, and the guide roll 58. A cylinder 81 is mounted to the assembly frame 100F1 and has a rod end 82 that extends movably from there. The rod end 82 is pivotally mounted to a connecting arm 83, which has the opposite end attached to a pivot pin 81P that engages with the guide roll 80F. The cylinder 81, rod end 82, connecting arm 83, and pivot pin 81P cooperate to move the guide roll 80F toward and away from the guide roll 80E. As shown in Figure 4A, the web transport and winding system 100 includes a rotary accumulator assembly 30 located downstream of the guide rolls 80C and 80D. The rotary accumulator assembly 30 includes a rail assembly 30A (e.g., two parallel tracks) mounted to the frame 100F or an adjacent structure. The core roll 30R is rotatably mounted on a shaft (not shown) that is movably fixed to the rail 30A at opposite ends of its shaft.To facilitate linear movement (e.g., horizontal movement) from the operating position of the shaft and core roll 30R (see Figure 4A) to the winding or construction position (see Figure 6), the transport position (see Figure 7A), and the unloading position (see Figure 10A), the shaft is mounted to the rail assembly so as to be movable (e.g., slidably, movable by a linear actuator, or movable by a rack and pinion guide). Before the cut web W is wound onto it, adhesive AD (see Figure 5B) is applied to the outer surface of the core roll 30R. The rotary accumulator assembly 30 is movable relative to the frame and includes a slitter knife 40 configured to cut the web W and separate the web W from normal downstream processing (i.e., detach the web W from its progress to the dual turret winding system 200).
[0036] The rotary accumulator assembly 30 includes a paster roll 30P that is rotatably mounted on the frame 100F and movable toward and away from the core roll 30R (e.g., guided movement along a horizontal trajectory). The paster roll 30P is configured to contact the web W and push the cut web W toward the core roll 30R so that the cut web W adheres to the core roll 30R by the adhesive AD on it (see Figure 5B). The paster roll 30P continues to push the cut web W toward the core roll 30R so that the web W is evenly wrapped around the core roll 30R. When the core roll 30R is full, the paster roll 30P retracts toward the core roll 30R.
[0037] The core roll 30R is in communication with a drive unit (not shown) which rotates the core roll 30R in the final stage of the transport process after the web W has been cut from its normal path, to facilitate the winding of the web thereon. The rotary accumulator system 30 includes a loader / unloader assembly 30H (e.g., an integrated hoist) having a pair of lift functions 30H1 and 30H2 (e.g., hooks, chain hoists, cables, etc.) adapted thereto. The lift functions 30H1 and 30H2 are configured to receive opposing ends of an axle, lift the axle and the loaded core roll 30R from the rail assembly 30A, and lower the loaded core roll 30R onto the cart 30C. The lift functions 30H1 and 30H2 are configured to receive opposing ends of an axle, lift the axle and a new empty core roll 30R and position it on the rail assembly 30A. As shown in Figure 7C, the rotary accumulator system 30 includes a standby idler roll 33 positioned below the core roll 30R and above the idler roll 57L. As shown in Figures 8C1 and 8C2, during the transition step from the rotary accumulator to the winding process of the winding spindle, the standby idler roll 33 guides the web W between the conveyor roll assembly 20 and the core roll 30R to provide a suitable cutting shape between the web W and the conveyor slitter 21.
[0038] As shown in Figures 5B, 8C1, 8C2, 12A, and 12B, the belt-type auxiliary conveyor assembly 60 includes a first continuous conveyor belt 60B assembled and driven around a pair of first conveyor rollers 60R1 and 60R2, and a second continuous conveyor belt 60B assembled and driven around a pair of second conveyor rollers 60R1 and 60R2. To facilitate the attachment of the web strip WN to the leader strip, a first conveyor roll 26A can be positioned adjacent to the opposite side of the first continuous conveyor belt 60B, and a second conveyor roll 26B can be positioned adjacent to the opposite side of the second continuous conveyor belt 60B. The belt-type auxiliary conveyor 60 is mounted to the frame 100F (see Figures 3 and 4) so as to move toward the roll conveying assembly 20 (see Figures 8D, 8E, and 8F) when the roll conveying assembly 20 is in the conveying position (for example, linearly), and so as to move away from the roll conveying assembly 20 (see Figures 9A, 9B1, and 9C) before and after conveying each of the pair of narrow web strips WN (see Figures 8C1 and 8C2) to the upper leader strip 52U and the lower leader strip 52L. For clarity, the pair of narrow web strips WN are indicated as WNU and WNL in Figure 9B2. As shown in Figure 9B2, the upper leader strip 52U is attached to the narrow web strip WNU by adhesive AD, and the lower leader strip 52L is attached to the narrow web strip WNL by adhesive AD.
[0039] As shown in Figure 24, the belt-type auxiliary conveyor assembly 60 includes two spaced-apart mechanisms, each also indicated by reference numeral 60. Each mechanism of the belt-type auxiliary conveyor assembly 60 includes a linear rail 67R mounted on a plate frame 66, and a linear bearing 67 that slides with the linear rail 67R and is mounted on a frame 100F. Each mechanism of the belt-type auxiliary conveyor assembly 60 includes a gearbox 65 mounted on the plate frame 66, and a motor 60M connected to the gearbox 65. The gearbox 65 is connected to a first conveyor roller 60R1 via a shaft and a unidirectional (i.e., clutched) radial bearing 64. The first conveyor roller 60R1 is thus driven in a unidirectional direction by the motor 60M and the gearbox 65. Each mechanism of the belt-type auxiliary conveyor assembly 60 includes a second conveyor roller 60R2, which is an idler roller rotatably mounted to a plate frame 66 via a shaft 69 and supported by a radial bearing 62. The continuous conveyor belt 60B is seated and wound around the outer circumferences of the first conveyor roller 60R1 and the second conveyor roller 60R2 and is driven by the first conveyor roller 60R1.
[0040] As shown in Figures 24 and 25, each mechanism of the belt-type auxiliary conveyor assembly 60 includes a cylinder 61 having an actuation rod 61A that extends movably from there. The tip of the actuation rod 61A is fixed to the plate frame 66. The cylinder 61 is assembled to the frame 100F via a bracket 61B. As shown in Figure 4A, the actuation rod 61A is extendable and retractable from the cylinder in response to the pressure of a fluid (e.g., hydraulic, pneumatic) applied to and released from the cylinder 61 in order to move the plate frame 66 and its attached components (e.g., a first conveyor roller 60R1, a second conveyor roller 60R2, and a continuous belt 60B) toward and away from the web W in direction L60.
[0041] As best shown in Figure 25, each mechanism of the belt-type auxiliary conveyor assembly 60 includes a guide plate 60G fixed to a plate frame 66. The guide plate 60G has a guide surface 60G1 that slides and engages with the underside 60B1 of the continuous conveyor belt 60B. The guide plate 60G ensures that the continuous conveyor belt 60B is held firmly against the rollers 26A and 26B that hold the web WN (i.e., prevents slack).
[0042] Referring to Figure 16, the roll conveying assembly 20 includes a support beam 22 movably mounted on the frame 100F by a support beam actuator system 22A, and a segmented roll 24 rotatably mounted thereto. The segmented roll assembly 24 includes a first end segment 24A and a second end segment 24B, with a central segment 24C positioned axially between the first end segment 24A and the second end segment 24B. A first conveying roll 26A is positioned between the first end segment 24A and the central segment 24C, and a second conveying roll 26B is positioned between the second segment 24B and the central segment 24C. As shown in Figures 23A, 23B, and 23C, the first end segment 24A, the second end segment 24B, and the central segment 24C are securely fastened to the support beam 22 via fasteners such as bolts 24Q. The web W permanently straddles the first end segment 24A, the second end segment 24B, and the central segment 24C. In some embodiments, the first end segment 24A, the second end segment 24B, and / or the central segment 24C include nozzles formed therefrom to discharge gases such as air in order to reduce friction between the web W and the first end segment 24A, the second end segment 24B, and the central segment 24C, and to help float or slide the web W over the first end segment 24A, the second end segment 24B, and the central segment 24C. In some embodiments, the first end segment 24A, the second end segment 24B, and the central segment 24C are rotatably mounted to a support beam 22. In some embodiments, as shown in Figures 8E1, 8E2, and 18, the nozzles 24N (e.g., holes or openings) are formed within or attached to the central segment 24C. The nozzle 24N is in communication (for example, via a manifold) with the internal region of the central segment 24C, which is provided with an air supply unit and connected to the nozzle 24N.The nozzle 24N discharges a gas such as air from the nozzle, pushing the narrow web strip WN (see Figures 8E1 and 8E2) downward along the belt-type auxiliary conveyor assembly 60 and guiding the narrow web strip WN to the web leader nip between guide rolls 80E and 80F. In the stowed position (raised position shown in Figure 16) and the forward position (i.e., a position between the stowed position shown in Figure 16 and the transport or lowered position shown in Figure 17), the first end segment 24A, the second end segment 24B, the center segment 24C, the first transport roll 26A, and the second transport roll 26B are coaxial with each other. The first end segment 24A and the second end segment 24B are approximately equal in length. The length of the first end segment 24A and the length of the second end segment 24B are each greater than the length of the center segment 24C. The lengths of the first conveyor roll 26A and the second conveyor roll 26B are each less than the length of the central segment 24C. The roll conveyor assembly 20 includes an actuation assembly 28 that is movably mounted to the support beam 22. As shown in Figures 18, 19, and 20A, the roll conveyor assembly 20 is fixed to the support beam 22 via a standoff support 31. A motor 28M is fixed to the top of the standoff support 31 via a coupling 31C. The actuation assembly 28 includes a first actuation rod 28A (e.g., a linear rail) and a second actuation rod 28B (e.g., a linear rail) coupled to each other by a cross member 28C. The first conveyor roll 26A is rotatably coupled to the first actuation rod 28A by a first bracket 29A (see Figure 17), and the second conveyor roll 26B is rotatably coupled to the second actuation rod 28B by a second bracket 29B (see Figure 17). The operating assembly 28 includes a first drive system 28A that translates the first transport roll 26A and the second transport roll 26B relative to the beam 22 (for example, so as to move away from the beam 22 downwards). The first drive system 28A includes a motor 28M and a lead screw 28Q coupled to a cross member 28C.Motor 28M rotates the lead screw 28Q, thereby moving the cross member 28C, the first actuation rod 28A, and the second actuation rod 28B in the upward direction of arrow Y and the downward direction of arrow X. The first actuation rod 28A and the second actuation rod 28B slide within corresponding pairs of linear bearings 31B, which are fixed to the lower portions of the standoff support 31 and the support beam 22.
[0043] As shown in Figures 18, 19, and 20A, the roll conveying assembly 20 includes a second drive system 22A configured to translate the roll conveying assembly 20 relative to the frame 100F (see Figure 4A for the frame 100F) (for example, upward in the direction of arrow Y, downward in the direction of arrow X, horizontally, and angularly). The second drive system 22A includes a first actuator system 22K arranged at the first end of the support beam 22, and a second actuator system 22K' arranged at the second end of the support beam 22. The first actuator system 22K includes a motor 22M fixed to the frame 100F via an assembly bracket 22J. A lead screw nut 22B is fixed to the support beam 22 in close proximity to the first end of the support beam 22. A lead screw 22D is connected to a motor, which is configured to rotate the lead screw 22D in a lead screw nut 22B to move the support beam 22 downward in the direction of arrow X and upward in the direction of arrow Y. A linear rail 22R is fixed to the frame 100F. A linear bearing system 22C is fixed to the first end of the support beam 22. The linear bearing system 22C is arranged to slide on the linear rail 22R in response to the movement of the support beam 22. A second actuator system 22K' is configured in the same way as the first actuator system 22K. In some embodiments, the first actuator system 22K and the second actuator system 22K' operate synchronously.
[0044] As shown in Figures 7C and 17, the roll conveying assembly 20 includes a conveying web slitter 21, which is pivotably fixed to a support beam 22 and assembled to translate-cut a narrow web strip WN (i.e., to separate or cut in an axial direction traversing the direction of travel of the web W, as indicated by arrow TT in Figures 12A, 12B, and 17). As best shown in Figures 22A and 22BC, the conveying web slitter 21 assembled to the roll conveying assembly 20 is pivotable in an arc-shaped path around a pivot pin 21P, as indicated by arrow 21A. An operating cylinder 21F is assembled to the support beam 22 via a mounting bracket 21N. The operating cylinder 21F has a rod end 21R that movably extends from the operating cylinder 21F. The rod end 21R is connected to the pivot pin 21P such that movement of the rod end 21R rotates the pivot pin 21P and the conveying web slitter 21 in the direction of arrow 21A. The transport web slitter 21 is shown in a retracted position close to the beam 22 in Figures 7C and 22A. In Figures 8E and 22B, the transport web slitter 21 is shown in an extended position, pivoted away from the beam 22 in the direction of arrow 21A to separate the narrow web strip WN from the core roll 30R.
[0045] As shown in Figures 11A and 11B, a method 400 for winding a web W and a transport system for a web processing system 100 are provided. The method first includes providing the web W to the web processing system 100 in normal operation 401. The method 400 includes a switching step 402 from a path to a turret winding system 200 to a rotary accumulator assembly 30. The switching step 402 includes engaging a paster roll 30P with a core roll 30R having adhesive on it (see Figure 5A), a slitter knife 40 cutting the web W from its path to the turret winding system 200 (see Figure 5A), the web W being transported to the rotary accumulator assembly 30 and beginning to wind the roll of web W onto the core roll 30R, and turning off the power to the turret winding system 200 and other equipment downstream of the rotary accumulator assembly 30 so that an operator can remove any problems in the turret winding assembly 200 and its path.
[0046] Method 400 further includes preparing a machine including a web processing system 100 for a rethreading step 403, in which an operator feeds out the prethreaded leader strip WP (see Figure 5A) (along with the leader strips 52U and 52L) to the turret winding assembly 200. This is done either by manual threading via the machine or by an automatic threading system which may be provided to safely transport and mount the prethreaded leader strip WP onto the spindle on the turret winding system 200 without requiring an operator to enter the internal machine area. The tail end of the prethreaded leader strip WP is positioned between guide rolls 80E and 80F, aided by a transport assist device 91 (see Figure 6). Adhesive such as tape is applied to the upper leader strip 52U and the lower leader strip 52L by an upper adhesive application system 54U and a lower adhesive application system 54L, respectively. At this point, the machine is ready to switch back to return to normal winding operation.
[0047] Method 400 further includes initiating a changeover step 404 to return from the rotary accumulator assembly 30 to the spindle on the turret winding system 200. Initiating the changeover step 404 involves retracting the core roll 30R to the transport position, moving the roll transport assembly 20 downward in the direction indicated by arrow X (see Figures 8E and 8F) to the transport position between the upper leader strip 52U and the lower leader strip 52L (see Figure 7A), and moving the belt-type auxiliary conveyor assembly 60 up to webline speed and into contact with the first transport roll 26A (i.e., a clutched roll that can rotate in only one direction) and the second transport roll 26B (i.e., a clutched roll that can rotate in only one direction). This includes: the edge trim slitter 70 moving to a transport position and engaging with the cutting section to produce a narrow web strip WN that is slightly wider than the upper leader strip 52U and the lower leader strip 52L (see Figures 8C1 and 8C2); the linear accumulator 10 engaging with the temporarily accumulated web to allow the downstream web to slow down slightly for transport; and the spindle on the turret winding system 200 rising to the transport speed, and then pulling the pre-thread leader WP, the upper leader strip 52U, and the lower leader strip 52L through the machine.
[0048] Method 400 further includes a conveyor roll assembly cutting step 405, which includes the conveyor web slitter 21 cutting the narrow web strip WN (see Figure 8E1), the first conveyor roll 26A and the second conveyor roll 26B extending downward along the belt-type auxiliary conveyor assembly 60 and guiding the narrow web strip WN to the web leader dip between guide rolls 80E and 80F, and the leader conveying system engaging with the tape conveying section, with the upper adhesive application system 54U and the lower adhesive application system 54L applying adhesive such as side tape to the upper leader strip 52U and the lower leader strip 52L. The narrow web strip WN intersects with the tape-fastened upper leader strip 52U and the lower leader strip 52L so that it can be guided to the winding spindle by the pre-threaded leader strip WP (taped on each side). The outer portion of the web W' (see Figures 8C1, 8C2, and 13), away from the center of the narrow web strip WN, is still wrapped around the core roll 30R at this point, as shown in Figure 8E1.
[0049] Method 400 further includes a retraction step 406, in which the roll conveying assembly 20 retracts upward in the direction indicated by arrow Y in Figure 9B1, the belt-type auxiliary conveyor assembly 60 retracts horizontally in the direction indicated by arrow X in Figure 9B1, the edge trim slitter 70 moves to its outer operating position and cuts the narrow edge trim strip WNT (see Figures 12A and 12B) that is still wrapped around the core roll 30R, the line speed increases to the normal operating speed, and the linear accumulator 10 begins to return to its operating position. The process includes the upper leader slitter 56U and the lower leader slitter 56L cutting the upper leader strip 52U and the lower leader strip 52L from the line, the leader clamp engaging to stop the upper leader strip 52U from the upper leader spindle roll 51U and the lower leader strip 52L from the lower leader spindle roll 52L, the edge trim WNT being guided into the trim chute 93 (see Figure 10B), and the roll change being initiated in the turret winding system 200 and transported to a new core. Once the edge trim strip WNT is guided into the trim chute 93, the web W' will not move any further toward the core roll 30R, and the rotation of the roll can be stopped.
[0050] Method 400 further includes an unloading step 407 in which the core roll 30R with the accumulated web W is retracted to the unloading position, as shown by the dashed line in Figure 10A. A loader / unloader assembly 30H (e.g., an integrated hoist) grips the core roll 30R with the web W wound around it, an accumulator arm assembly (i.e., rail assembly 30A) releases the latch from the core roll 30R, the loader / unloader assembly 30H drops the core roll 30R onto a cart 30C or the floor for removal from the machine area (see Figure 10A), a new core roll 30A is prepared with tape for the rotating accumulator assembly 30 and returned to the rail assembly 30A by the loader / unloader assembly 30H, and the core roll 30R moves to the transport-ready position. The operator can initiate transport if there is another web disturbance.
