- ABSTRACT Mechanism for doffing large packages of roving from a mandrel of a winder.
- the mechanism includes an upright stand mounted on a base which, in turn, is supported on wheels.
- a plate is slidably supported for vertical movement on the stand and is moved in a vertical direction by a fluid-operated ram, the piston rod of which is connected to the plate through a cable.
- a first elongate arm is pivotally mounted on the plate for pivotal movement in a vertical plane.
- a transverse arm extends outwardly from an end of the first arm and an elongate supporting member is connected to the transverse arm and located generally parallel to the first arm.
- the elongate supporting member has guide means at an end to enable the elongate member to be aligned with the mandrel to receive a roving package and a sleeve on which it is wound which are slid off the mandrel onto the elongate member.
- the base also has means cooperating with means on the floor adjacent the winder for positioning the overall mechanism relative to the mandrel.
- the elongate supporting member has resilient bands forming annular chambers around the member which are inflated to engage and hold the roving package. With the package held on the elongate supporting member, the mechanism is moved to a location spaced from the winder with the package over a pallet. The supporting member is then pivoted to a vertical position and lowered to place the package on the pallet. Air is then exhausted from the resilient bands and the elongate supporting member raised to separate it from the package.
- This invention relates to doffing mechanism for handling large packages of wound fibers.
- the present invention relates to doffing mechanism for removing a package from a mandrel of a winder, transporting the package to a pallet, and depositing the package thereon.
- the apparatus includes a verticallyextending stand mounted on a base which, in turn, is supported on suitable wheels or casters.
- the stand includes vertical guide rails on which is mounted a plate.
- the stand also has a fluid-operated ram having a cable connected to the plate to move the plate vertically with respect to the rails when the ram is operated.
- a housing is associated with the stand and encloses a small hydraulic pump and a battery for operating same.
- a first elongate arm has a central portion pivotally supported by the plate and a transverse arm is affixed to an end of the first arm and extends outwardly therefrom.
- An elongate supporting member has an end affixed to an outer end of the transverse arm with the elongate supporting member being positioned generally parallel to the first arm, the three elements forming a U-shaped configuration.
- the free end of the elongate supporting member has guide means engageable with an end of the mandrel on which the large package of roving is wound, to facilitate alignment of the elongate supporting member with the mandrel.
- the base of the mechanism further includes means cooperating with positioning means on the floor to position the mechanism in a receiving location relative to the mandrel.
- the elongate supporting member has two spaced, resilient bands thereon forming annular fluid chambers. Passage means communicate with these chambers and extend through the elongate supporting member to a valve arrangement by means of which fluid can be supplied to the bands to expand the annular chambers and engage a sleeve or tube on which the roving package is wound.
- a fluid-opeated, package-engaging member is also employed to engage the end of the package opposite the free end of the mandrel, thereby to slide the package off the mandrel and onto the supporting member. At this time, the resilient bands are expanded to firmly engage the package.
- the overall mechanism is then rolled on the wheels of the base to the pallet and the package positioned thereover.
- the elongate supporting member is pivoted to a vertical position and lowered with the end of the package engaging the pallet, and the air being exhausted from the resilient bands, enabling them to contract and separate from the package, or specifically from the sleeve on which it is wound.
- the elongate supporting member is then raised until the free end of the member is clear of the package. At this time, the member can be pivoted back to the horizontal position and the mechanism moved into position adjacent the mandrel or another mandrel to receive another wound package.
- Another object of the invention is to provide mechanism for handling a large package, which mechanism engages the package through a central opening therein by means of resilient bands expandable by fluid pressure.
- Still another object of the invention is to provide doffing mechanism for removing large fiber packages from a mandrel and for transporting them to a pallet by only one man.
- a further object of the invention is to provide doffing mechamism for removing large packages from a mandrel by engaging the interior of a sleeve on which the package is wound, and transporting the package thereby.
- Yet a further object of the invention is to provide apparatus for doffing a roving package from a mandrel and transporting it to a receiving platform more quickly and easily.

- FIG. 2 is a plan view of the apparatus of FIG. 1;
- FIG. 3 is a view in elevation taken along the line 3-3 of FIG. 1;
- FIG. 4 is a view similar to F l0. 3 of the doffing mechanism, but showing a portion of the mechanism in an unloading position;
- FIG. 5 is an enlarged, fragmentary plan view of a modified portion of the doffing mechanism
- H6. 6 is an enlarged, detailed view in section, taken along the line 6-6 of FIG. 5;
- FIG. 7 is a fragmentary view in elevation of a pivotal connection of the doffing mechanism.
- FIG. 8 is a fragmentary detailed view taken along the line 8-8 of FIG. 2.
- a suitable winder with which the invention can be employed is indicated at 10, and basically includes a housing 12, an expandable mandrel 14, and a level wind device 16.
- the housing 12 contains suitable drive and control mechanism for operating the mandrel l4 and the level wind device 16.
- the mandrel 14 has three expandable segments 18, the positions of which are controlled by an end knob 20 which can be turned to move the segments 18 in and out.
- the level wind device 16 includes an eye 22 for directing roving back and forth along the mandrel 14, as is well known in the art.
- a large cylindrical package of roving is wound on the mandrel l4 and specifically on a sleeve or tube, preferably of flexible material, positioned over the mandrel 14.
- the roving is basically formed in the usual manner, from a plurality of smaller packages of strand mounted on a creel, with the strands from the packages collected and twisted into the roving which is then wound onto the mandrel 14. In this instance, a large package in the order of 300- 500 pounds is produced, this taking several hours to complete.
- the completed package is then removed, after the mandel segments 18 are collapsed by rotation of the knob 20, and the package is transferred to a pallet on which it is shipped, typically in groups of four, to a customer.
- the customer Because of the extensive length of the roving in the package, the customer has relatively few knots to tie to connect roving ends. This substantially reduces labor time and also improves the quality of the products which inherently will have fewer knots therein. Since the single large package requires less space than a large number of small ones of equal total weight, shipping space and storage space are correspondingly reduced, with inventory and other handling problems being correspondingly simplified. Any problem with pilferage of small packages also is eliminated.
- the present invention provides doffing mechanism indicated at 26 (FIGS. 1-3) which overcomes the above problems and has other advantages.
- the doffing mechanism 26 can be handled readily by one man and the package can be doffed and taken to the pallet quickly and easily. Further, the outer surface of the package 24 is not engaged by the doffing mechanism so that possible damage to the roving is correspondingly reduced.
- the mechanism 26 includes a base 28 formed by a tubular member comprising two legs 30 and 32 connected by a rear transverse leg 34.
- the base 28 is mounted on front and rear wheels 36 to move the doffing mechanism 26 into position relative to the winder l and to transport the doffed package.
- a V-shaped channel 38 is affixed to the floor in a predetermined position near the winder and receives an end of the base leg 32 to place it in a predetermined position.
- Diagonally opposite the forward end of the leg 32 is a drop pin 40 located in a tubular bracket 42 affixed to the base 28. The lower end of the pin 40 is received in a recess 44 formed in the floor in a predetermined position.
- the channel 38 and the recess 44 in cooperation with the pin 40, thereby fully locate the base 28 to the doffing mechanism 26 in a predetermined position relative of the winder, in order to enable the doffing mechanism 26 to more readily receive the package 24 from the winder.
- An, upright stand indicated at 46 is mounted on base cross members 48 (FIGS. 3 and 4) and basically includes a channel-shaped member 50 having a rear wall 52 and side walls 54 and 56 terminating in outwardly extending flanges 58 and 60 (see also FIG. 5).
- the flanges 58 and 60 form guide rails for a front plate 62 having L-shaped flanges 64 and 66 extending around the flanges 58 and 60 so that the plate 62 is guided for vertical movement on the flanges 58 and 60.
- a circular mounting plate 68 (see also FIG. 7) is centrally affixed to the front plate 62. To move the plates 62 and 68 vertically, a flexible member or cable 70 (FIGS.
- a fluid-operated ram 74 is located within the channel formed by the member 50 and has a piston rod 76 extending upwardly and terminating in a pulley 78 which engages an intermediate portion of the cable 70.
- the plates 62 and 68 are raised when the piston rod 76 is extended and lowered by means of gravity when the piston rod 76 is retracted.
- a reservoir, a pump, and a battery can be located in a housing 77 behind the channel member 50 to operate the cylinder 74.
- a stop assembly 80 is mounted on the side wall 56 of the member 50 adjacent the flange 60.
- the stop assembly 80 includes a supporting plate 82 which is movable with the front plate 62 and slidably carries a stop pin 84 by means of ears 86.
- a spring 88 urges the stop pin 84 toward the channel side wall 56.
- the pin 84 In its normal forward position toward the wall, the pin 84 can engage a triangular stop member 90 on the side wall 56 to automatically position the plates 62 and 68 in a desired vertical position relative to the mandrel 14.
- the pin 84 is retracted by a lever 92, the plates 62 and 68 can be lowered.
- a package engaging and supporting unit indicated at 94 (FIGS. 5 and 7) is mounted on the circular plate 68.
- the unit 94 includes a circular plate 96 which is pivotally connected to the circular plate 68 by a pin or axle 98.
- a first elongate arm 100 is affixed to the circular plate 96 through an elongate bracket 102 and an intermediate plate 104.
- a transverse arm 106 is structurally integral with an end of the first arm I00 extending outwardly from the channel member 50 and terminating in an elongate supporting member 108.
- the member 108 is substantially parallel to the first arm 100 and is spaced therefrom a distance exceeding the radius of the package 24.
- the elongate supporting member 108 has a central core or supporting arm 110 which is structurally integral with the transverse arm 106.
- the supporting member includes a rear stop flange 112 and two cylindrical sections 114 mounted on the supporting arm 110 by annular flange members 116.
- Two resilient bands 118 also extend around the arm 110 and are held in position by the annular flange members 116.
- the bands 118 When not expanded, the bands 118 are of a diameter equal to the sections 114, and being smaller than the diameter of the sleeve on which the package is wound.
- fluid such as air is supplied to annular resilient chambers 120 formed by the bands 118, they expand toward the dotted line position, as shown in FIG.
- the air can be supplied through one of the flanges 116 into the side of the band 118 by a line 122 which extends through the arms 110, 106, and 100 back to a point near the channel member 50 where a valve and a suitable fitting (not shown) can be located through which air under pressure can be supplied.
- a guide member 124 which includes a guide wall 126 extending outwardly therefrom.
- the guide wall 126 is preferably semi-cylindrical, being open on one side.
- This guide wall is of a size to be received around the end knob of the mandrel 14 thereby to facilitate alignment of the elongate supporting member 108 with the mandrel 14.
- the thickness of the wall is about equal to the difference in diameters of the segments 18, when slightly retracted, and the knob 20.
- the stop assembly 80 is located in a manner to position the guide member 123 at the same height as the knob 20 when the stop pin 84 engages the stop member 90.
- the supporting member 108 can then be moved into alignment with the mandrel 14 by moving the mechanism 26 in from the side with the leg 32 aligned with the channel 38.
- the package 24 can be slid off the mandrel 14 and onto the elongate supporting member 108 by a package sliding device 128 (FIG. l-3) located on the winder housing 12.
- This device includes a fluidoperated cylinder 130 having a piston rod 132 terminating in an ejection plate 134.
- the cylinder 130 is affixed to the top of the housing 12 with the plate 134 located adjacent the front of the housing, between it and the package being formed.
- the plate 134 engages the end of the package and slides it onto the elongate supporting member 108.
- the package sliding device 128 can be mounted on the first arm 100 of the unit 94, if desired.
- the plate 134 in this instance, is pivotally mounted so it can clear the package 24 on the mandrel 14 when the piston rod 132 is extended, with the plate then being swung to a position behind the rear of the package 24. Fluid is then supplied to the rod end of the cylinder to retract the piston rod and cause the plate 134 to slide the package onto the elongate supporting member 108.
- the drop pin 40 can be raised from the recess 24 and the doffing mechanism 26 wheeled to a platform or pallet 136 (FIG. 4) with the legs 30 and 32 of the base 28 extending under the pallet so that the elongate supporting arm 108 and the package 24 are positioned thereabove.
- the elongate supporting member 108 is pivoted to a vertical position and the stop pin 84 is then retracted to enable the package to be lowered by gravity toward the pallet 136.
- the stationary, circular plate 68 has an arm 138 extending upwardly therefrom and the pivotable circular plate 96 has a similar arm 140 extending therefrom.
- the arm 138 pivotally carries a cylindrical member 142 and the arm 140 pivotally carries an internally-threaded cylindrical member 144.
- the latter engages a threaded portion 146 of a crank 148 having a crank arm 150 extending outwardly from a rear end thereof, and the member 140 rotatably receives an intermediate portion of the crank arm and is prevented from longitudinal movement with respect thereto.
- the arm 140 moves outwardly from the arm 138 to the final position shown in FIG. 4.
- the member 108 is in vertical position with the package likewise being vertical.
- the air to the resilient bands 118 can be released to enable the chambers to retract to the normal position and release the package sleeve.
- the plate 62 is subsequently raised by operation of the hydraulic ram 74 until the lower end of the supporting member 108 is free of the package 24 resting in its on-end position.
- the supporting member 108 can then be moved back to its horizontal position and the mechanism wheeled to another winder to receive another package or back to the same winder, as the case may be.
- the doffing mechanism according to the invention has a number of advantages. Only one man is required to remove the package from the mandrel 14, transfer it to a loading platform or pallet, and unload the package thereon. The operation is relatively simple and can be done quickly. Further, the outer cylinder surface of the package is never engaged by the doffing mechanism. The doffing mechanism due to the U-shaped configuration of the supporting member and the arms, also requires little space beyond the length of the package for doffing.
