Abstract

A turret winder (10) for winding web material (40) on spindle-supported cores (32) has a turret (20) which is moveable into three indexing positions (A, B, C), one of which is a web transfer, cutting and winding station (B), and another of which is a winding completion station (C). Frames (12, 13) adjacent to the turret (20) support carriages (65, 70) which support a secondary lay-on roll (80). The carriages (65, 70) include a primary carriage (65) which is moveable vertically with respect to the turret (20) and a lay-on roll carriage (70) which is moveable horizontally with respect to the primary carriage (65). The lay-on roll carriage (70) has an arm (85) which is engaged by the turret (20) during movement of the spindle (29) between the above two positions so that arcuate movement of the spindle (29) is translated to movement of the lay-on roll carriage (70) in such a manner that the lay-on roll (80) accurately follows the movement as the building roll (55) moves to the winding completion station (C).

Description

CONTINUOUS WINDER BACKGROUND OF THE INVENTION This application relates to turret-type network winders and, more particularly, to a winder that includes a primary positioning cylinder and auxiliary positioning cylinders that act in conjunction with a roll in formation to prevent air is carried by a winding network between the network and the corrugations of the cylinder. In turret-type winders, a positioning cylinder is used on which the net passes before the net is fastened to the surface of the forming roll. By partially wrapping the incoming network over the positioning cylinder, a clamping point can be formed with the forming roll in which air is excluded between the network and the cylinder while the roll in formation is in the winding station. However, before completion of the cylinder, it must be separated or moved to a winding termination station so that a newly placed core can be carried to the winding station, and so that the network can be cut and transferred to the winding station. core when the winding of the roll in formation is finished, thus starting a new roll in a new core. The now finished roll is separated or moved to an exit station where the roll is removed and a new core is inserted into the spindles. During the separation movement from an individual winding station, the auxiliary positioning cylinder has the task of excluding the air and then sends the roll to the winding termination station and continues to function as a positioning cylinder until the roll is completely formed. The auxiliary positioning cylinder picks up the net and secures it to the forming roll during the transfer, and maintains the ratio as the roll in formation moves to the finishing station. As the auxiliary positioning cylinders have been mounted to the turret itself, this causes unnecessary complications due to the need to operate the positioning cylinders on a rotating or moving member, increases the weight of the turret and requires that said auxiliary positioning cylinder is dedicated to a given position in the turret. When the turret includes three or more winding spindles or axes, this configuration becomes complicated and expensive. Therefore, there is a need for a more simplified and positive configuration whereby a positioning cylinder can be related to a forming roll and make it precisely follow the movement of the forming roll from an initial network formation station to a winding termination station. BRIEF DESCRIPTION OF THE INVENTION Therefore, this invention is directed to an improved turret winder for winding paper, plastic film or other network material in cores supported by spindles, where a turret is mounted for gradual rotation to carry the spindles and the cores therein successively from a network cutting station and primary training, to a winding termination station, and then to a roll exit station and new core loading. The opposite ends of an auxiliary positioning cylinder are mounted between the primary support carriages and end structures that are independent of the turret. The auxiliary positioning cylinder is positioned along side sides of the turret in the general vicinity of the primary training station. The primary support trolleys are mounted on the end structures for limited vertical movement. Each of the carriages of the secondary support positioning cylinders can be moved generally horizontally on the respective primary carriages between a retracted position and an advanced or operating position. The positioning cylinder carriages have a rigid member such as an arm which, when moved to the operating position, is aligned so as to engage a bearing or hub positioned on the axis of a cylinder spindle. As a result, the movement of the spindle between the first forming station and the winding termination station causes the primary carriage to move, concurrently on its generally vertical axis due to the constraint between the turret and the carriage arm. The auxiliary positioning cylinder is mounted or placed in a fixed relation to the arm so that while the arm is in contact with the spindle bearing, the auxiliary positioning cylinder holds the forming roll substantially in the region of convergence of the network that is running with the roll in formation. The positioning function is continued by the auxiliary positioning cylinder in the rest of the transfer at the roll termination station. As the rotary movement of the turret translates into vertical movement of the primary carriage, a geometric relationship is maintained between the auxiliary positioning cylinder and the forming roll during the separation movement and subsequently, with the second carriage retracting laterally as necessary in the primary carriage to accommodate the curved movement of the cylinder during separation and the larger size of the forming roll after separation. In this way, a roll without cuts is formed along the cutting end of the network. In the apparatus of this invention, the position of the auxiliary positioning cylinder is directly related to the position of the axis of the spindle of the forming roll during the movement of the turret from the moment of coupling with the secondary carriage arm to and through the formation end of the roll. Then, an envelope angle of the network in the auxiliary positioning cylinder can be maintained while the roll formation is finished. The apparatus of the invention further includes a combined electrostatic charge bar and blade carriage. A rotary cutting blade configuration or other network cutting configuration is mounted on this carriage together with an electrostatic charging bar. The carriage can be moved between a retracted position in which the network cutting apparatus and the loading bar are positioned remotely with respect to the network that is running. However, when a network cut and transfer is desired, the carriage moves along rails mounted on the side structures and in an operating position with respect to the network going to a separate forming roll and a new core. on a spindle at a winding start station. The cutting device of the network and the loading bar, in the advanced or operating position of the car, presents a load for the network and for the core accompanied by a cut of the network to allow an immediate wrapping of the network in the core By means of the primary positioning cylinder and subsequently, the carriage of the loading bar and blade can be retracted. Therefore, an important object of the invention is to provide a turret-type winder without cut-outs in which an auxiliary positioning cylinder is mounted on a movable carriage, and the position of the positioning cylinder is directly related to the position of the axis of the spindle of the role in formation. A further object of the invention is to provide a turret winder for winding paper or plastic film material on cores supported by spindles, in which a turret is mounted for rotation on a horizontal axis and on which an auxiliary positioning cylinder is mounted. in a secondary car which, in turn, is mounted on a primary carriage for orthogonal movement with respect to the movement of the primary carriage, and in which the carriages are temporarily coupled to a spindle of a forming roll as the roll is carried in the turret between a winding position and a roll finishing position, to provide a smooth transfer of a primary positioning cylinder to the auxiliary positioning cylinder. A more particular object of the invention is the provision of a turret winder, as mentioned above, in which a positioning cylinder trolley has an arm that can be placed to engage with a bearing in the hub of a spindle moving between a winding station and a winding termination station, so that the carriage of the positioning cylinder moves in a geometric relationship with the spindle of the turret as the spindle of the turret moves between said stations. Other objects and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the Figures of the drawings, which represent a preferred embodiment of the invention, a turret-type winder constructed in accordance with this invention is generally shown at 10 in Figure 1 and has a pair of lateral structures 12 and 13 laterally separated substantially identically in and between which are mounted the components of the rotary winder. The side structures are supported on a suitable floor and are connected or joined by beams 14 and 15.

A three station or three position winding turret is generally illustrated at 20. In each end structure, the turret has a circular support plate 22 mounted on saddle bearings 23 on the end plates, and is actuated by an activator. of separation 25. Individual motor activators 28 are provided for each of the three winding spindles 29, and rotate with the turret. The spindles 29 each support a core in which the network is wound, it being understood that the core can be placed on the spindles by means of a suitable core charger. Figure 1 shows a finished roll 60 that has been cut and formed into segments corresponding to the width of the knives in a machine cutter, although the invention is not limited to a winder for cutting material only. For the purposes of this invention, the turret itself is of conventional construction, in which the end plates of the turret 22 are in the saddle bearings 23 in the openings in the end plates 12 and 13. The turret is shown having three spindles but the turret can be designed with more or less than three if desired. The description and operation of the positioning cylinder assemblies and the network cutting assembly are best observed and understood with reference to the partially diagrammatic views of Figures 3 to 6 seen in the end structure 13. The structure illustrated in Figures 3 to 6 it is, of course, repeated in reverse in the structure of the opposite end of the apparatus. The turret in Figure 3 is shown in one of its three separate positions, corresponding to the spindle locations shown. Each spindle has a core represented by the number 32. The separate positions, shown in Figures 3 to 6, can be referred to as the roll loading and exit station at the 9 o'clock position, the cutting station of the network, network transfer, and initial roll formation at 5 o'clock, and the finishing station of the forming roll at the 1 o'clock position. For simplicity in this description, these separation stations can be referred to hereinafter as station "A", station "B" and station "C", respectively. The incoming network 40 is carried on a series of guide rollers 41, 42 and 43 that extend between the lateral structures of the winder and, if the net has been trimmed, the trimmed portion is removed from the net by a roller 44. If the machine is equipped with a cutter, it is placed between the rollers 42 and 43. The remaining net is carried between a pair of pick-up rollers 45 and 46 and on lower guide rollers 47 and 48 and on a primary positioning cylinder 50. The positioning cylinder 50 is mounted to the side structure in a arm 51 and is controlled by a cylinder 52. The spindle and the rollers rotate counterclockwise as seen in Figure 3. In Figure 3, it will be seen that the network 40 is applied in slightly wrapped relationship to the primary placement cylinder 50 to core 32 at station "B" which will define and become a forming roll 55 on turret 20. Station "B" is the primary formation station at which a larger portion of the size of the roll is achieved while being held by the positioning cylinder 50. Figure 3 also illustrates a finished roll 60 in station "C". It is important to be able to separate the forming roll 55 at station "B" to the finishing station "C" while continuing an uninterrupted winding process and while applying the network with a positioning cylinder. For this purpose, a secondary positioning cylinder assembly includes a primary positioning carriage 65 which is mounted for generally vertical movement in the side structures on the vertical rails 66. The weight of the carriage 65 is mainly carried by a cylinder 68 attached to the lateral structures 12 or 13. A secondary positioning cylinder carriage 70 is mounted on the primary positioning carriage 65 for generally horizontal movement, as seen in Figures 3 to 6, on a rail 72 attached to the primary carriage. The movement of the carriage 70 is controlled by cylinders back to back 75. The respective carriages 70 in each end structure are joined by a crossing member 76. The secondary carriages 70 can be moved in the respective primary carriages 65 between a retracted position as shown in lf ß and an extended operating position as shown in Figures 3 and 4. In the extended position, an auxiliary positioning cylinder 80 is placed by the carriage 70 to receive, without intervention, the net and the roll in formation 55 as the roll is separated between positions B and C, as described in greater detail below.

The auxiliary positioning cylinder 80 is fixed in position in the secondary carriage 70, and, during the initial portion of the separation, it is accelerated by the motor 82 and is brought into contact with the periphery of the forming roll 55 as it begins to be carried away. the turret from station "B" to station "C". The carriage 70 is in the "ready" or standby position as shown in Figure 3. The primary positioning cylinder 50 will be partially retracted due to the size of the roll in formation. At the point where the forming roll 55 (Figure 4) leaves the primary positioning cylinder 50, this roll now becomes a guide roll for the network and guides the net over the auxiliary positioning cylinder 80. During this movement , the secondary carriage 70 moves to the right on the rails 72 as necessary to accommodate the curved movement of the forming roll 55 during separation. The cylinder 75 operates to apply the desirable clamping pressure on the roll 80 with the circumference of the roll 55 while maintaining a small degree of winding in the auxiliary positioning cylinder 80. The secondary carriage 70 includes the feature of being provided with a medium to inter-relate the position of the primary carriage 65 with respect to the axis of a winding spindle, as the spindle and the roll move from position B to position C. For this purpose, the secondary carriage 70 is formed with an arm integral extending transversely 85. The lower surface of the arm 85 is provided with a horizontally flat flange 90. During the transfer of the forming roll from its initial forming position shown in Figure 3 towards the terminating station "C" , the spindle on which the training net is mounted moves through an intermediate position, as shown in Figure 4. In this position intermediate n, the arms 85 in the planar flange 90 move into contact with a hub bearing enlarged cylinder 92. The buckets 92 are positioned at each end of each spindle and are in coaxial alignment with the axis of the respective spindle. The hubs 92 form a temporary interconnection between the movement of the associated spindle and the carriages, 65 and 70, by means of which the curved or translational movement of the spindle is transferred directly as a free lift to the arm 85. Also, in this position, approximately 90% of the weight of the carriages 65 and 70 is supported by the cylindrices 68, so that the remaining 10% forces the assembly towards a lower position. As the partially formed roll is separated, the associated hub 92 engages the arm 85. This occurred approximately after 30 ° to 40 ° rotation. The continuous rotary movement of the turret causes the primary carriage, which is counterbalanced by the cylinders 68, to be lifted on the rails 66 carrying with it the secondary carriage 70 and the auxiliary positioning cylinder 80. This relationship is maintained until completion of the formation of the roll, as illustrated in Figure 5. As the turret 20 is not separated until the roll forming in station "B" reaches a substantial size, in the range of approximately 70 to 90% of its diameter complete, a relatively fixed geometrical relationship is maintained by the concurrent movement of the carriages 65 and 70 once the arm 85 has coupled the bearing hub of the associated spindle 92. The auxiliary positioning cylinder 80 is maintained in a position such that the The net always wraps the cylindro 80 before making contact with the roll in formation. The geometrical relation is changed only slightly by the fact that the roll in formation will increase its diameter after separation to station "C". The curved movement of the roll 55, as well as its increase in diameter, after separation, is accommodated by the translation movement of the carriage 70 on the rail 72 and accompanied by the winding movement of the arm 85 on the surface 90 as length of the associated bearing hub 92. The cylinder 75 maintains a suitable winding pressure. The weight of the set of the carriages 65 and 70 is substantially supported by the air actuators 68 so that the main portion of the weight of the combined carriages is relieved, thus limiting the effort required to translate the separation movement of the turret in a lifting or lifting movement of the combined carriages 65 and 70. Figure 5 illustrates the position of the parts during the cutting and transfer of the network to a new core in station "B" and prior to the removal of a completely rolled roll 60 in station "A". The cutting and transferring of the network is carried out by means of components mounted on a network cutting blade carriage 100 at each end structure 12, 13 which can be moved horizontally on the guide rails 102 associated with each of the respective end structures. The carriages 100 are joined together for common movement by a cross member 105 and occupy a normally retracted position, as shown in Figures 3, 4 and 6. The carriages 100 are secured and fixed in the retracted position, as shown in the Figure 3, by means of a downwardly extending arm 101 mounted on the carriage 65 which, when the carriage 65 is lowered, engages a cam roller or roller 106 on the carriage 100 preventing any inadvertent movement of the carriage 100 from its rest position. or stored. During the cutting and transfer of the net, the carriage 65 is raised thereby releasing the arm 101 of the roller 106 and then the carriage 100 moves to an operating position as shown in Figure 5. The carriage 100 has a blade assembly rotary 1 10. The rotating knife assembly includes a cutting blade 1 12 and a mesh driving rod 1 13. In the cutting position of the carriage 100, the rod 1 13 folds the tensioned net, and the blade rotates clockwise in bar 1 13, as shown in Figure 5, and is carried through the network. Additionally, the carriage 100 has an electrostatic charging bar 120 which is activated concurrently with the firing of the blade 12 to place an electrostatic charge on the network and the core, and thus help to join the network to a core in the station. B "in Figure 5. The electrostatic charge bar 120 can be made and operated generally in accordance with US Pat. Ser. No. 4,678,133 and the U.S. Patent of North America Serial Number. 4, 770, 358, except that the load bar is not mounted on an arm. After said cutting and transfer of the network to a new core in station "B", the roll in station "C" is fully wound. The carriage 100 retracts to its resting position. The carriage 70 can be raised to the position shown in Figure 6. In this position, the carriage 70 and the arm 85 are now completely free of the finished roll and can be lowered to the position shown in Figures 3 to 6. With the particular geometry of the invention as shown in Figures 1 to 6, which represent a preferred embodiment, rolls of large diameter or rolls of maximum design size for the particular turret, are transferred or separated between stations B and C and, for a very brief moment of time, the network that is running while making contact with the roll in formation 55 will be pressed by the auxiliary positioning cylinder 80 l slightly into the point at which the network makes contact with the roll in formation. The air is excluded by maintaining a substantial pressure between the cylinder 80 and the forming roll during said separation until the roll arrives at station "C", at which point the network will make contact with the positioning cylinder before it makes contact with the roll in formation. The separation is carried out very quickly and is carried out in a time between approximately 1 to 3 seconds while a sufficient clamping pressure is used to eliminate trapped air. The winder of this invention is also particularly designed for rolls in formation of a diameter smaller than the maximum diameter of roll 55 as shown in station "C" in Figure 5. The condition of transferring a roll between stations B and C for a smaller diameter roll is illustrated in Figure 7, wherein similar parts are indicated with the same reference numbers as those used in Figures 1 to 6. The only difference is that the diameter of the forming roll 55a being separated is smaller than that of roll 55 of the rolls 55a. Figures 1-6 and the geometry is such that, at no time the network that is running comes in contact with the roll in formation before making contact with any of the placement cylinders. In Figure 7 it will be seen that the running network moves at the fixing point at the convergence between the positioning cylinder 80 and the surface of the forming roll 55a. Therefore, with a smaller roll, the time during which the running net is allowed to contact the surface of the forming roll before being pressurized by the positioning cylinder is reduced or eliminated. This condition may be desirable for sticky or stretched films that are subject to poor winding quality if the air is trapped between the layers. The angle of the network stroke to the clamping point between the cylinder 80 and the forming roll can be adjusted and controlled by the position of the primary cylinder 50 after it interrupts contact with the surface of the roll in moving formation. The operation of the turret winder for winding netting material, in accordance with this invention, is most apparent from the foregoing description. It will be understood that the core 32 is placed in the spindle at station "A" and moved to station "B" by rotating the turret 20 to achieve the position and condition illustrated in Figure 3. Assuming that the network 40 it has been cut and transferred by means of the electrostatic charge bar 1 13 to the core 32 in the station, the formation will begin by activating the winding of the center of the spindle motors 28 while the network is partially wrapped and held by the positioning cylinder pri mario 50, polarized by the activator 52. The roll will be allowed to continue to be formed to a substantial size before separation is required, and the carriages 65 and 70 can be carried from the position shown in Figure 6 to the position shown in FIG. Figure 3. That is, the carriage 65 is lowered and the secondary carriage 70 moves to its operative position shown in Figure 3. At a selected point in the formation of the roll 55, the turret 20 is for carrying the auxiliary positioning cylinder 80 in contact with the surface of the forming roll. The motor 82 is used to bring the positioning cylinder 80 to speed, and the separation returns the positioning cylinder, the roll 50 rotates on the axis of rotation of the arms 51 and the cylinder 80 moves horizontally with the movement of the carriage 70 against the loading of the activator 75. After approximately 30 ° to 40 ° of rotation, the surface of the forming roll 55 lifts the primary positioning cylinder 80 and the net then runs on this cylinder and directly to the defined clamping point between the positioning cylinder 80 and the roll in formation. When the positioning is under the control of the auxiliary positioning cylinder 80, the separation is continued with the surface 90 of the arm 85 coming into contact with the outer race of the hub bearing 92 and all the additional rotational movement to the position C is then related to a corresponding retraction and lifting movement of the carriages 65, 70. After the arm 101 releases the roller 106, the carriage of the knife 100 can then be moved on the rail 102 to the operating position shown in Figure 5. When the formation of the roll is finished based on the diameter of the roll in position C, the arc blade assembly 10 can be fired to bring the blade 12 through the network and simultaneously the static bar 120 is activated to load the network relative to the adjacent core 32, to affect the transfer of the cutoff end of the network 40 on the surface of the core, and the winding of the roll in formation is now finished. In the next separation step, the roll formed now moves to station "A" where it is removed, and a new core is loaded. While the shape of the apparatus described herein constitutes a preferred embodiment of this invention, it should be understood that the invention is not limited to this precise form of apparatus, and that changes can be made therein without departing from the scope of the invention being defined. in the appended claims.
