PACKING SYSTEM FOR HEAT SET

FIELD

This disclosure relates to systems and methods for handling yarn packages.

BACKGROUND

Conventionally, yarn packages formed on a winder of a heat set are handled by an operator. The operator cuts a yarn sample, ties a loose end of the yarn package, and stacks the yarn package on a pallet. This requires a substantial number of operators and exposes the operators to typical occupational hazards. Accordingly, a way to reduce direct operator interaction is desirable.

Further, conventionally, an operator cuts a yarn sample from a yarn package to dye and test the sample for quality assurance purposes. An operator subsequently ties the loose end of the yarn package to secure the package. This operation exposes operators to typical occupational hazards. Accordingly, a way to reduce direct operator interaction is desirable.

SUMMARY

Described herein, in various aspects, is a system having at least one winder configured to wind yarn to form a yarn package. At least one sampling and tying machine is configured to remove a portion of the yarn of the yarn package and tie off a free end of the yarn around the yarn package to inhibit the yarn package from unwinding. A dunnage supply area has therein at least one support structure for receiving a plurality of yarn packages thereon. The system further includes at least one case assembly area and a robotic arm. The robotic arm is configured to move the yarn package from the at least one winder to the at least one sampling and tying machine: move the yarn package from the at least one sampling and tying machine to the at least one case assembly area: and stack the yarn package on a support structure in the at least one case assembly area.

In another aspect, a method includes winding, by a winder, yarn to form a yarn package. A robotic arm moves the yarn package from the winder to at least one sampling and tying machine. The robotic arm moves the yarn package from the at least one sampling and tying machine to a case assembly area. The robotic arm stacks the yarn package on a support structure in the at least one case assembly area.

Also described herein, in various aspects, is a system for sampling and tying yarn of a package having a free end. The system includes a spindle and a first actuator. The first actuator is configured to rotate the spindle in a first direction and opposed second direction. A yarn sampling assembly is configured to receive a portion of the yarn comprising the free end. A yarn tying assembly is configured to tie a knot in the yarn of the package to prevent unwinding of the yarn from the package.

In another aspect, a method includes receiving a package comprising yarn on a spindle. The yarn has a free end. A first actuator coupled to the spindle rotates the package to deliver the free end to a sampling assembly. The sampling assembly removes a portion of the yarn comprising the free end to provide a yarn sample and to form a new free end of the yarn remaining on the spindle.

INTRODUCTION

Disclosed herein, and with reference to FIGS. 1 and 2, is a system 10 for handling yarn. The system 10 permits automation for handling yarn packages from once they have been formed on one or more winders 10. For example, the system 10 can move yarn packages from the winder(s) 20 to a sampling and tying machine 30 by a robotic arm 60. The sampling and tying machine 30 can be configured to remove a portion of the yarn of the yarn package and tie off a free end of the yarn around the yarn package to inhibit the yarn package from unwinding. Once the yarn package has been sampled and the free end of the yarn has been tied, the robotic arm can stack the yarn to form a case 50. In some aspects, the case can comprise yarn packages stacked on one or more support assemblies (referred to herein collectively as dunnage). Automated guided vehicles (AGVs) can remove cases and deliver dunnage for forming additional cases.

EXEMPLARY EMBODIMENTS

In some aspects, the system 10 can comprise at least one winder 20 configured to wind yarn to form a yarn package 22 as is known in the art. The at least one winder 20 can be, for example, a winder of a heat set apparatus 24 as is known in the art. Typically, the winder receives yarn following a heat setting process, and the winder is configured to wind the yarn (for example, around a substrate such as a tube or cone) to form yarn packages 22. The winder can have a driven roller in contact with the yarn package. The driven roller can rotate the yarn package to wind yarn around the substrate (e.g., as the yarn leaves the heat set apparatus 24).

The system 10 can further comprise at least one sampling and tying machine 30. Each sampling and tying machine 30 can be configured to remove a portion of the yarn of the yarn package 22 and tie off a free end of the yarn around the yarn package to inhibit the yarn package from unwinding. The sampling and tying machine(s) 30 can deliver yarn into respective sample drawers 32. A quality control specialist can retrieve the samples in the sample drawers 32 for testing. Further aspects of exemplary sampling and tying machine(s) 30 are described in detail herein.

The system 10 can comprise a dunnage supply area 40 having therein one or a plurality of support structures 42 for receiving a plurality of yarn packages thereon. The support structures 42 can include pallets 44 that can form bottoms of a case 48 (shown without yarn packages to include detail of the support structures) as well as spacers 46 that are positioned between adjacent layers of yarn packages. Optionally, a spacer 46 can also form a top layer (e.g., a cap) of a case 48. Each of the support structures 42 can comprise features that support the position of the packages positioned thereon. For example, the support structures 42 can define cylindrical recesses 43 that are configured to support the yarn packages 22 and maintain the yarn packages in particular spacing. The pallets 44 can further define receptacles 45 for receiving forks of a fork truck.

The system 10 can comprise at least one case assembly area 50 for forming cases 48. In some optional aspects, each case 48 can comprise a pallet 44 defining a bottom of the case. One or more layers of yarn packages 22 can be stacked on the pallet 44. For example, the case 48 can comprise one layer, two layers, three layers, four layers, or more than four layers of yarn packages 22. Spacers 46 can be positioned between each layer of yarn packages 22. Optionally, a spacer 46 can define a top of the case 48.

Referring to FIG. 5, in further exemplary aspects, the pallet 44 can be a sheet. For example, the pallet 44 can be a cardboard sheet. In exemplary aspects, the pallet can be a flat cardboard sheet. In further aspects, each spacer 46 can be a sheet (e.g., a cardboard sheet). In some aspects, the pallet 44 and the spacers 46 can be similar or identical. For example, the same types of cardboard sheets can be used as both the pallet 44 and the spacers 46. Thus, in some aspects, the support structures can be interchangeable. In these aspects, elements for managing the stack of support structures comprising different elements (such as a staging rack) can be omitted. Optionally, the pallet 44 and spacers 46 can have horizontal dimensions that are slightly smaller than the case 48 so that the yarn packages 22 on the outer edges extend outwardly from the pallet 44 and the spacers 46.

The system 10 can comprise a robotic arm 60. The robotic arm 60 can be configured to move each yarn package 22 from the one or more winders 20 to the one or more sampling and tying machines 30. The robotic arm 60 can then move the yarn package 22 from the at least one sampling and tying machine 30 to the at least one case assembly area 50 and stack the yarn package 22 on a support structure 42 in the at least one case assembly area 50.

In some aspects each winder 20, each sampling and tying machine 30, the dunnage supply area 40, the at least one case assembly area 50, and the robotic arm 60 can be within a locked-out area 70. For example, the system 10 can comprise a barrier 72 that surrounds the locked-out area 70. The barrier 72 can comprise at least one retractable door 74 that selectively permits access to the locked-out area 70. For example, a retractable door 74 can be positioned in front of each case assembly area 50 and the dunnage supply area 40. In this way, dunnage can be delivered, and cases 48 can be removed. Each retractable door 74 can comprise an actuator 76 that is configured to rotate in a first direction to roll the door upwardly and in a second direction to lower the door.

In some aspects, each case assembly area 50 can comprise a conveyor 52. The conveyor 52 can be, for example, a belt conveyor. The conveyor 52 can move a case 48 out of a respective retractable door 74 and onto an AGV 90. Similarly, the dunnage supply area 40) can comprise a conveyor 52 that receives support structures 42 from an AGV 90 and moves the support structures into the system through a retractable door 74.

In exemplary aspects, the support structure(s) 42 in the dunnage supply area 40 can include at least one pallet 44, at least one spacer 46, or a combination thereof. For example, the support structures 42 can be provided to the dunnage supply area 40 according to ratios in which the support structures are used. For an exemplary system that is configured to form a case 48 having one pallet 44, four layers of yarn packages 22, spacers 46 between each layer of yarn packages and a spacer 46 defining a top of the case, the case can use, in total, one pallet 44 and four spacers 46. Dunnage can, therefore, be delivered in the same ratio of four spacers 46 and one pallet 44, and arranged in the order in which completed cases. For example, as shown in FIG. 2, the support structure(s) 42 can be provided in a stack of alternating pallets 44 and a corresponding number of spacers 46 used with each pallet. A single dunnage delivery can comprise a plurality of pallets (e.g., 2, 3, 4, 5, or more pallets) and a corresponding ratio of spacers.

The robotic arm 60 can further be configured to handle the support structures 42. For example, the robotic arm 60) can be configured to move a support structure 42 of the at least one support structure in the dunnage supply area 40 to the at least one case assembly area 50. For example, the robotic arm 60 can place a pallet in an empty case assembly area. The robotic arm 60 can place spacers 46 on top of completed layers of yarn packages 22.

The robotic arm 60 can comprise a dual-function end of arm tool (EOAT) 62. The EOAT can comprise a first gripper that is configured to grip a yarn package. In some exemplary aspects, the first gripper can comprise a plurality of projections that can be inserted into the tube of a yarn package 22 and move radially outwardly from each other to bias against inner surfaces of the tube. For example, the first gripper can comprise two, three, four, or more projections that move radially outwardly. The projections can be retracted inwardly to release the yarn package. The EOAT 62 can further comprise a second gripper for gripping and releasing the support structures 42. The second gripper can comprise, for example, a vacuum gripper. For example, the EOAT can comprise a vacuum supply (e.g., a pump) and one or more suction cups 64 (six shown) that are in communication with the vacuum supply and configured to apply negative pressure from the vacuum supply to grip the support structure.

The system 10 can further comprise a staging rack 80 that is configured to store at least one support structure from the dunnage supply area. For example, as shown, a single stack of support structures is provided for supplying two case assembly areas 50. Accordingly, it can be understood that the top support structure 42a of the stack of support structures 42 can be either a pallet or a spacer. Depending on the current stack the partially assembled case 48 requiring the next support structure, it may or may not need the top support structure 42a of the stack of support structures 42. Thus, the robotic arm 60 can pick from either the top support structure 42a or the staging rack 80. The robotic arm 60 can further take the top support structure 42a and position it on the staging rack, thereby exposing a lower support structure below the top support structure. Accordingly, the system 10 can be configured to track inventory of the order of the support structures 42 in the dunnage supply area 40) as well as the support structures 42 on the staging rack 80. The staging rack 80 can be configured to hold at least one support structure 42, at least two support structures 42, or exactly two support structures 42.

The system 10 can further comprise one or a plurality of automated guided vehicles (AGVs) 90. The AGV(s) 90 can be configured to deliver the support structures 42 to the dunnage supply area 40. The AGV(s) 90 can further be configured to carry the cases 48 from the case assembly area 40. Each AGV 90 can comprise a conveyor 92 that is configured to align with a respective conveyor 52 to transfer support structures 42 and cases 48.

In some aspects, the at least one winder 20 can comprise two winders. In some aspects, the at least one sampling and tying machine 30 can comprise two sampling and tying machines. In some aspects, the at least one case assembly area 50 can comprise two case assembly areas. The system 10 can comprise logic that is configured to control transfer yarn packages from a first winder, to a first sampling and tying machine, to a first case assembly area, and to control transfer yarn packages from a second winder, to a second sampling and tying machine, to a second case assembly area.

Referring to FIG. 3, in some aspects, a global system 100 can comprise a plurality of systems 10 as disclosed herein and a plurality of AGVs 90 to deliver dunnage to and receive cases from the plurality of systems 10.

In further or alternative aspects, and with reference to FIGS. 5-6, a conveyor 120 (e.g., a roller conveyor) can receive the case 48 from the conveyor 52 and carry the case from the winder 20. For example, the conveyor 52 can comprise tracks 53 that can move horizontally to carry the case 48 laterally. The tracks 53 can then move vertically downwardly to place the case 48 on the conveyor 120.

In some optional aspects, case 48 can be wrapped in a wrapping material (e.g., polymer wrap). For example, referring to FIGS. 6 and 7, the conveyor 120 can carry the case 48 from the case assembly area 50 to a first wrapper 130 that is configured to wrap the case about a first axis (e.g., a horizontal axis). In exemplary aspects, the first wrapper 130 can surround the case 48 so that the case 48 is receivable therein. The first wrapper 130 can comprise an actuator 132 that moves a material roll 134 around a periphery of the case about the first axis to wrap the wrapping material around the case 48. In exemplary aspects, the first wrapper can comprise a wheel that rotates around the package, and the material roll 134 can be mounted to the wheel. In some aspects, the first axis can be parallel to, or substantially parallel to, an axis of movement of the conveyor 53.

In further aspects, a second wrapper 140 can be configured to wrap the case 48 about a second axis (e.g., vertical axis). For example, referring to FIG. 8, the second wrapper 140 can provide wrapping around the case 48 so that said wrapping surrounds a vertical axis that extends through the case 48. In some aspects, the second wrapper 140 can comprise a rotatable platform 142 that rotates to thereby rotate the case 48 relative to a second roll of wrapping material. The second wrapper 140 can further comprise a stabilizing plate 144 that is vertically movable to be positioned on top of the case 48. The stabilizing plate 144 can retain the case 48 on the rotatable platform 142 as the rotatable platform rotates relative to the roll of wrapping material so that said wrapping material is applied to an outer periphery of the case.

A method can comprise winding, by a winder 20, yarn to form a yarn package 22. A robotic arm 60 can move the yarn package 22 from the winder 20 to at least one sampling and tying machine 30. The robotic arm 60 can move the yarn package 22 from the at least one sampling and tying machine 30 to a case assembly area 50. The robotic arm 60 can stack the yarn package 22 on a support structure 42 in the at least one case assembly area.

In some aspects, the robotic arm 60 can stack a first layer of yarn packages on a pallet 44, place a spacer 46 on the first layer of yarn packages 22, and stack a second layer of yarn packages on the spacer 46. In further aspects, the robotic arm 60 can stack a second layer of yarn packages and a second spacer 46 on the second layer of yarn packages.

In one aspect, the end of arm tool 363 can be the first gripper 358 of the yarn sampling assembly 350, wherein the yarn 23 of the remaining portion of the free end 25 remains gripped by the first gripper 358. After the sample of yarn is cut, the first gripper 358, gripping the remaining free end 25 of yarn 23, can be used to tie the remaining free end 25 of yarn 23 around the yarn package 22.

The yarn tying assembly 360 can further comprise a first surface 362 and a second surface 364. The first surface 362 and second surface 364 can be spaced along a first axis 370. In one aspect, the first surface 362 and the second surface 364 can comprise a first rod 367 and a second rod 369. Further, the first rod 367 and second rod 369 can extend along a second axis 372 which is substantially perpendicular to the first axis 370. The first surface 362 and second surface 364 can be configured to engage yarn 23 of the yarn package 22. For example, the end of arm tool 363, controlled and moved by the multi-axis robotic arm 361, can circle the first surface 362 and second surface 364 to loop the remaining free end 325 of yarn 323 around the first surface 362 and second surface 364. The path of the end of arm tool 363, and therefore, the remaining free end 25 of yarn 23 is illustrated by arrow 365 in FIG. 16 and FIG. 17. The looped yarn 23 around the first surface 362 and second surface 364 creates a through opening 376.

The yarn tying assembly 360 can further comprise a tying gripper 366. The tying gripper 366 can be positioned between the first surface 362 and the second surface 364 along the first axis 370. The tying gripper 366 can be configured to receive the remaining free end 25 of yarn 23. For example, the end of arm tool 363, controlled and moved by the multi-axis robotic arm 361, can circle the first surface 362 and second surface 364, wrap around the yarn package 22. and feed the remaining free end 25 of yarn 23 through the tying gripper 366 as shown by arrow 365 in FIG. 16 and FIG. 17. The tying gripper 366 can comprise opposed gripping surfaces 374 that can be configured to move toward and away from each other. When the opposed gripping surfaces 374 are away from each other or spaced apart. the remaining free end 25 of yarn 23 can pass between the opposed gripping surfaces 374. The opposed gripping surfaces 374 can then move towards each other to pinch or grip the remaining free end 25 of yarn 23. In one aspect, the opposed gripping surfaces 374 can include a protruding edge 377 and a recessed edge 378 that is complementary to the protruding edge 377. Further, the protruding edge 377 and the recessed edge 378 can have respective and complementary wedge shapes.

Further, the protruding edge 377 can comprise a protrusion, and the recessed edge 378 can comprise a slot configured to receive the protrusion when the tying gripper 366 closes. These exemplary configurations of the opposed gripping surfaces 374 ensure the remaining free end 25 of yarn 23 is secured by the closed tying gripper 366.

The yarn tying assembly 360 can comprise a second actuator. The second actuator can be configured to move the yarn 23 engaged on the first surface 362 and second surface 364, relative to the yarn 23 in the tying gripper 366 and along the second axis 372. In one aspect, the second actuator can comprise a pusher 381 configured to push the yarn 23 off the first rod 367 and the second rod 369. Further, the pusher 381 can push the yarn 23 off the first rod 367 and the second rod 369 by pushing a plate 379 configured to engage with the yarn 23. When the yarn 23 is pushed off the first surface 362 and second surface 364, the yarn 23 looped around the first surface 362 and second surface 364 is pushed past the tying gripper 366 securing the remaining free end 25 of yarn 23, and the remaining free end 25 of yarn 23 is pulled through the through opening 376 created by the looped yarn 23, thereby creating an overhand knot in the yarn 23. In one aspect, after the yarn 23 is pushed off the first surface 362 and second surface 364, the first actuator 330 can rotate the spindle, and therefore, the yarn package 22, in the second direction indicated by arrow 34 in FIG. 18, while the remaining free end 25 of yarn 23 remains gripped by the tying gripper 366. When the yarn package 22 is rotated in the second direction, the overhand knot created by the yarn tying assembly 360 is pulled tight.
