  • the drive pulley 40and the traversing cam 42 are affixed to a common shaft 48.
  • the shaft 48 is rotatably supported by bearings (not shown) that are mounted in the traverse housing 50. These bearings support the shaft 48 intermediate the drive pulley 40 and the traverse cam 42 and at its outer end. With this construction when the drive pulley 40 is rotated the cam 42 is caused to rotate about the axis of shaft 48.
  • the cam 42 is provided with a pair of continuous spiral grooves 52 and 54 with transition grooves 56 at each end of the cam connecting the spiral grooves 52 and 54 together.
  • the spiral groove 52 is a left hand helix and the spiral groove 54 is a right hand helix. These helices have the same pitch and consequently guide the strand guide 38 back and forth across the face of the package 32 at the same rate.
  • the strand guide 38 is slidably mounted on a support bar 58 and is provided with a cam follower 60 which is received within and guided by the grooves 52 and 54 to accurately reciprocate the guide 38 back and forth across the face of the package 32.

  • the strand starting guide 46 is mounted on the outer end of the traverse housing 50 above the guide bar 44.
  • the strand starting guide 46 is a piston type double acting air cylinder which is connected by pneumatic lines to a valve (not shown). By manipulating the valve the air cylinder can be actuated to extend or retract a piston rod which has an enlarged portion or guide 62 at its outer end. An outer surface of the guide 62 is aligned with a cylindrical starting surface 64 on the mandrel assembly 36.
  • the guide 62 diverts the strand 30 from its normal position which would be centered with respect to the traverse assembly 34 to the outer end of the traverse assembly where it is aligned with the starting surface 64 of the mandrel assembly 36.
  • the strand 30 moves back toward the center of the traverse assembly where it is automatically picked up by the strand guide 38 for the winding of the package 32.
  • the mandrel assembly 36 comprises the mandrel 66 which carries the package 32 and a shaft 68 on which the mandrel 66 is rotatably mounted.
  • the mandrel assembly 36 is a motor with the mandrel 66 forming the rotor of the motor and the shaft 68 forming the stator of the motor.
  • This motor is the sole driving means for both the mandrel assembly 36 and the traverse assembly 34.
  • One end of the shaft or stator 68 is mounted in a clamping block 70 on a carriage assembly 72.
  • the clamping block 70 supports the shaft and the mandrel is in turn, supported on the shaft or stator 68 by a bearing 74 near the clamping block 70 and a similar bearing not shown at the outer end of the shaft 68.
  • the shaft or stator 68 is hollow and an electrical cable 76 for the motor pass from an electrical box 78 throughthe hollow shaft 68 to the windings of the motor.
  • the mandrel 66 includes a main portion which receives paper tubes for the packages 32 and an extension having a pulley 80 thereon.
  • the pulley 80 is aligned with the drive pulley 40 of the traverse assembly. In this way, the mandrel motor not only effects the rotation of the mandrel 66 but also provides a drive for the traverse assembly 34.
  • the carriage 72 which supports the mandrel assembly 36 is slidably mounted on a pair of horizontally extending support rods 82 and 84 which are bolted or otherwise secured at their ends to the cabinet or frame of the assembly.
  • the support rods 82 and 84 are parallel with respect to each other and extend perpendicular to the longitudinal axes of both the traverse assembly 34 and the mandrel assembly 36.
  • the support rods 82 and 84 serve to both support and guide the carriage 72 in a direction which is perpendicular to the axes of the mandrel assembly 36 and the traverse assembly 34 so that the mandrel 66 with the package 32 thereon can be withdrawn from the traverse assembly 34 while being maintained in the correct orientation with respect to the traverse assembly 34 to assure the proper formation of the package 32.
  • the carriage 72 is also provided with a hydraulic double acting piston type cylinder assembly 86 for effecting the movement of the carriage along the support rods 82 and 84 both toward and away from the traverse assembly 34.
  • a hydraulic double acting piston type cylinder assembly 86 for effecting the movement of the carriage along the support rods 82 and 84 both toward and away from the traverse assembly 34.
  • One end of the cylinder of the piston assembly 86 is secured by a bolt 88 to the cabinet while the other end of the housing is received within a recess 89 of the carriage 72.
  • the outer end of the piston rod 90 of the cylinder is secured to the carriage 72 by a bolt 91.
  • a four-way solenoid valve assembly (not shown) is provided to exhaust hydraulic fluid from one side of the piston to a resevoir while admitting pressurized hydraulic fluid to the other side of the piston from a pressure line to effect the movement of the piston and consequently the carriage 72.
  • the valve is a three-position valve and is spring centered so that it normally is in its neutral position wherein both ports to the hydraulic cylinder 86 are closed. Upon actuation the valve is shifted from its neutral position to admit and exhaust hydraulic fluid from the cylinder 86 and thereby effect movement of the carriage.
  • the drive train of the winding apparatus includes an idler pulley 92 secured to the carriage 72 and an adjustable idler pulley 94 mounted on the frame of the assembly.
  • the idler pulley 92 is rotatably mounted on a shaft 96 which is secured by means of a clamping block 98 to the carriage 72.
  • the axis of rotation of the idler pulley 92 is parallel to the axes of rotation of the pulleys 40 and 80 and the pulley lies in the same vertical plane as pulleys 40 and 80.
  • the axis of rotation of the idler pulley 94 is also parallel to the axes of rotation of pulleys 40 and 80 and the pulley 94 lies in the same vertical plane as pulleys 40 and 80.
  • the adjustable idler pulley 94 is rotatably mounted on a shaft 100 which is secured to a slide 102 by a pair of bolts 104.
  • the slide is provided with a pair of depending blocks 106 which extend parallel to the axis of shaft 100 and are slidably mounted on a pair of rods 108 extending through the blocks and perpendicular to shaft 100 in a generally horizontal plane.
  • the rods 108 which provide both support and guidance for the slide 102, are mounted in a pair of support blocks 110 and 112 that are affixed to the frame of the strand winding assembly.
  • a shaft 114 is provided to effect movement of the slide 102 and consequently the idler pulley 94.
  • One end of the shaft 114 is rotatably supported in a collar which is mounted in block 110.
  • the collar 120 permits the shaft to rotate but prevents axial movement to the shaft 114 relative to the block 110.
  • the other end of the shaft 114 is threaded and is received in threaded apertures within blocks 106. Consequently, by turning the shaft 114, the idler pulley 94 can be adjusted in a plane which includes the other pulleys of the drive assembly.
  • the idler pulley 94 can be adjusted to provide the proper tension in a double sided toothed timing belt 1 16 which is trained about the pulleys.
  • a set screw 122 can be tightened to prevent further movement of the shaft 114.
  • the traverse drive pulley 40 and the idler pulley 94 are both mounted on the cabinet or frame of the assembly and remain stationary during the winding operation of the apparatus.
  • the mandrel pulley 80 and the idler pulley 92 are both mounted on the carriage 72 and move with the carriage 72 as the mandrel 66 recedes from the traverse assembly 34 during the winding operation.
  • the mandrel pulley 80 lies intermediate the traverse drive pulley 40 and the idler pulley 94.
  • the line of travel of the belt from the traverse drive pulley 40 to the idler pulley 92 is parallel to the line of travel of the belt between the mandrel pulley 80 and the idler pulley 94.
  • a sensing unit 124 of the winding apparatus detects the diameter of the package 32 and actuates the four way valve for the hydraulic cylinder 86 to move the carriage 72 and consequently the mandrel 66 in accordance with the package diameter so that the mandrel 66 is properly positioned relative to the traverse assembly 34.
  • the sensing unit 124 includes a roller bail 126 which extends the entire length of the package 32 and is supported by a pair of arms 128 which are affixed to a shaft 130.
  • the roller bail 126 is a thin walled alumi num tube with a gas bearing mounted in each end that is in turn secured to one of the arms 128.
  • the gas is supplied to the bearing from a source of pressurized air through bores in the shaft arms 128 and shaft 130. Since the roller bail 124 turns on gas (compressed air) bearings, there is no friction and very little inertia. Thus the roller bail 124 exerts little or no drag on the strand 30.
  • the shaft 130 is rotatably mounted in the traverse assembly housing 50 and extends through the cabinet of the winding apparatus.
  • the shaft 130 has a collar 132 affixed thereto which is provided with a radially extending arm 134.
  • a spring 136 extends between and is secured to both the arm 134 and a bolt 138 in the frame of the apparatus.
  • the spring 136 which is in tension exerts a clockwise torque (as viewed in FIG. 6) on the shaft 130 which in turn exerts a clockwise torque on the roller bail 126 to urge it into contact with the surface of the package 32.
  • the force exerted is approximately 3 pounds which is distributed by the roller bail 126 across the entire surface of the package 32. This force is sufficient to keep the bail in contact with the package but the force is not high enough to damage the strand 30 as the strand is wound onto the package 32.
  • the collar 132 also includes a boss 140 which has a rod 142 mounted therein.
  • the rod 142 extends upward from the boss 140 and has an upper end which is located adjacent a switch 144 which activates the valve for the hydraulic cylinder 86.
  • the actuating arm 146 of the switch 144 and the rod 142 are normally separated when the surface of the package 32 is in the correct position relative to the strand guide 38. However, as the package 32 builds in diameter the roller bail 126 is forced away from the mandrel 66 and rotates the shaft in a counter clockwise direction thereby bringing the rod 142 into contact with the actuating arm 146 of the switch 144.
  • the switch is a touchswitch wherein contact between the rod 142, which is a grounding rod, and the actuating arm 146 of the switch completes the circut to actuate the valve for the hydraulic cylinder.
  • the four-way valve for the hydraulic cylinder 86 is actuated to move the mandrel 66 away from the traverse assembly 34 to thereby reposition the surface of the package 32 in the correct location relative to the strand guide 38. This allows the roller bail 126 to rotate in a clockwise direction under the influence of the spring 136 to bring rod 142 back to its original position and deactuate the valve for the hydraulic cylinder.
  • a piston of a hydraulic'shock absorber or dash pot 148 is connected to another arm 150 extending out from the collar 132 to dampen or eliminate any sudden movements of the roller bail 126.
  • the hydraulic shock absorber 148 comprises a hydraulic cylinder 150 with inlet-outlet ports 152 and 154 on either side of the piston.
  • the inlet-outlet ports 152 and 154 are connected by means of a fluid conduit 156 having a valve 158 therein to regulate the flow of fluid from one side of the piston to the other to thereby impede the movement of the piston and consequently, the rotation of the shaft 130 to prevent any sudden movement.
  • the strand 30 is first passed on the outside of the starting guide head 62, over the guide bar 44 and onto the surface 64 of the mandrel. As mentioned before, the starting surface 64 is beyond the paper tube on which the package is wound. As the mandrel 66and the traverse assembly 34 are accelerating to their operating speeds the strand is wound on the starting surface 64 of the mandrel. When the mandrel 66 and the traverse assembly 34 have reached their operating speeds, a timed relay switch actuates the strand guide cylinder 46 to retract the starting guide. Once the strand guide 62 is no longer contacting the strand 30, the strand shifts toward the center of the traverse assembly 34 where it is picked up by the reciprocating strand guide 38.
  • the strand guide 38 guides the strand back and forth across the paper tube and commences to build the package 32 on the paper tube.
  • the roller bail 126 is pushed farther and far ther away from the axis of the mandrel thereby causing the shaft 130 to rotate in a counterclockwise direction to bring the rod 142 into contact with the switch 144 that actuates the valve for the hydraulic cylinder 86.
  • the mandrel 66 is moved a small increment away from the traverse assembly 34 to again bring the surface of the package 32 into the proper position relative to the strand guide 38.
  • the mandrel motor not only turns the mandrel 66 but also pulley 80 which in turn drives the belt 1 16.
  • the belt 116 which is also trained over the pulley 40 as well as the idler pulleys 92 and 94 drives the traverse assembly 34 at a'rate which is directly proportional to the speed of the mandrel 66.
  • the mandrel 66 can be moved relative to the trasverse assembly 34 without having to utilize separate drive trains for the mandrel 66 and the traverse assembly 34.
  • the mandrel motor is provided with a conventional programmer which programs the motor to slow down as the diameter of the package 32 increases. This is done to provide a constant draw rate by maintaining a constant speed for the surface of the package 32.
  • the constant draw rate by the mandrel 66 together with the constant angle of introduction and departure of the strand 30 from the strand guide 38 and the constant angle of introduction of the strand 30 to the package 32 effected by movement of the mandrel 66 rather than the traverse assembly 34 permits a constant tension to be maintained on the strand 30. Since the traverse assembly 34 is driven by the mandrel 66 and since the speeds of these two elements are directly proportional, the traverse assembly 34 is slowed down as the mandrel 66 is slowed down which also contributes to the precision winding of the package 32. The strand is accurately guided onto the package 32 by the cam 42 and strand guides 38.
  • roller bail is held in contact with the package 32, to assure proper actuation of the hydraulic cylinder 86 to move the mandrel, without exerting any drag on the strand 30. Consequently, the apparatus of the present invention forms an excellent package well suited for use in subsequent processes.
