The winding rolls are automatically stopped each time a filled batch is removed and an empty core is automatically released from the magazine A trough receives the filled batch and a fabric cutter is positioned between the trough and the winding rolls. The fabric cutter is effective to restart the winding rolls after each cutting operation and also activates an air blast to blow the severed leading edge of the fabric into engagement with the empty core.
PATENTED JANI 9 [an I SHEET 2 (1F 3 I NVEN T 0R5 FRANK CATALLO 1 DONALD FOREMAN ATTORNEY PATENTEB mu 91911 $556,424 sum BM 3 INVENTORS 4 FRANK CATALLO DONALD FOREMAN a hni. 27 ATTORNEY FABRIC BATCHER THE INVENTION This invention relates generally to new and useful improvements in winding and reeling equipment and particularly seeks to provide a simple, inexpensive semiautomatic machine for batching relatively small diameter rolls of fabric from a continuously supplied fabric web.
The current trend in many portions of the textile industry is toward the continuous or near continuous production and finishing of the goods, whether knitted or woven. In many instances this requires the use of high-speed automatic, complicated and expensive batching equipment in which the continuously travelling fabric web emerging from a processing machine or a range of synchronized processing machines, must be continuously batched or wound into rolls containing a predetermined length of fabric or of a predetermined diameter, after which the web must be severed and its lead end automatically transferred to a new core which also must be automatically positioned at the winding station. Any web speed in excess of a very few hundred feet per minute requires this type of automatic equipment. HOwever, the batching of knit fabrics at linear speeds on the order of 75 yards per minute does not require or warrant the investment in such expensive and complicated fully automatic batchers, although the batching should be able to be effected without either slowing or stopping the processing machines from which the fabric to be batched emerges.
Therefore, an object of this invention is to provide a novel fabric batcher particularly suitable for use in connection with processing machines that continuously operate at moderate linear speeds.
Another object of this invention is to provide a fabric batcher of the character stated that includes a two-roll drum or surface winder normally operating at a surface speed substantially equal to the lineal output speed from an associated fabric-processing machine but periodically stoppable to permit the removal of a fabric batch without necessitating either the slowing down or stopping the associated processing machine.
Another object of this invention is to provide a fabric batcher of the character stated that includes a storage compartment to receive and temporarily retain the continuously advancing fabric each time the surface winder is stopped for removal of a roll of batched fabric and further includes a speedup drive for taking up the stored fabric each time a new roll is batched.
Another object of this invention is to provide a fabric batcher of the character stated that includes a receiving trough for each completed fabric batch and a manually operated cutoff knife interposed between the trough and the surface winder for severing thefabric.
Another object of this invention is to provide a fabric batcher of the character stated that includes a magazine for mandrel-mounted cores and release mechanisms to cause a core to be dropped into winding position each time a new fabric batch is to be wound.
A further object of this invention is to provide a fabric batcher of the character stated that includes an intermittently operable air blast for transferring the severed lead end of the fabric web into winding engagement with each freshly supplied core.
A further object of this invention is to provide a fabric batcher of the character stated that is simple in design, rugged in construction and economical to manufacture.
With these and other objects, the nature of which will be apparent, the invention will be more fully understood by reference to the drawings, the accompanying detailed description and the appended claims.
In the drawings:
FIG. 1 is an end elevation, looking toward the delivery end, of a fabric batcher constructed in accordance with this invention;
FIG. 2 is an enlarged vertical transverse section taken along line 2-2 of FIG. 1;
FIG. 3 is an enlarged fragmentary detail side elevation taken along line 3-3 of FIG. 1;
FIG. 4 is an enlarged horizontal section taken along line 4-4 of FIG. 1',
FIG. 5 is an enlarged transverse section taken along 55 of FIG. 1; and
FIG. 6 is an enlarged detail section taken along line 6-6 of FIG. 2.
Referring to the drawings in detail. the invention. as illustrated, is embodied in a fabric batcher that includes a pair of spaced parallel side frames 5,5 between which are journaled a pair of horizontally spaced parallel winder rolls 6,6 adapted to be driven in the same direction of rotation from a drive unit 7 through an electric clutch 8 and sprocket and chain means 9 for normal speed operation or through an electric clutch 10 and sprocket and chain means 11 for a somewhat higher speed operation.
A core magazine, generally indicated 12, which is adjustable both to its lateral position and to its width, is supported on a pair of horizontally spaced parallel rods or tubes 13,13 extending transversely between the side frames 5,5 and includes a pair of generally C-shaped sideplates 14,14 slidable mounted on the rods 13. Opposed sleeves 15,15 and clamps 16,16 are provided adjacent the lower ends of the sideplates 14 for preventing lateral sway of the sideplates and for clamping them into position at any desired location along the rods 13.
The sideplates l4 carry a pair of upwardly extending symmetrically opposed channels 17,17 that are adapted to receive and retain a supply of empty cores 18 each of which is mounted on a freely removable mandrel 19.
The under face of each channel 17 is provided with a detent lug 20 pivotally mounted thereon and adapted to be oscillated into and out of a slot in the channel face by an air cylinder 21 each time a fresh core 18 is to be dropped into engagement with the winder rolls 6 to start a new fabric batch.
In further accordance with this invention, means are pro vided to automatically stop the winding rolls 6 each time a filled batch is to be removed in order to allow time to sever the fabric and pass the free severed end into engagement around a fresh core 18 that has been released from the magazine 12. To this end an abutment or trigger plate, generally indicated 22 (see FIGS. 1, 3 and 4), is pivotally mounted on one of the magazine sideplates 14 with its inner edge portion 23 positioned across the path of travel of a roll mandrel 19 after the fabric batch has wound to its desired diameter. It will be understood that the vertical length of the inner edge portion 23 must be sufficient to span the full range of paths of travel of the mandrels from minimum to maximum diameters of the fabric batches. The outer edge portion 24 of the plate 22 serves as an abutment for contacting the actuating element of a microswitch 25. A pair of torsion springs 26,26 resiliently bias the inner edge 23 of the plate 22 toward its associated channel 17. When a filled batch is manually removed laterally from the winder rolls 6,6 its mandrel 19 will engage the inner edge portion 23 of the plate 22 and force the plate to oscillate about its pivot, thus actuating the microswitch 25 to stop the winder rolls 6,6 and to cause a suitably installed solenoid valve (not shown) to actuate the air cylinder 21 and permit a fresh (empty) mandrel and core to slide down the channels 17,17 into engagement with the fabric resting on the stopped winding rolls.
As indicated in FIG. 2 of the drawings each filled batch is simply rolled off from the winding rolls 6,6, across a cutter track, generally indicated 27, and into a receiving trough 28 from which it is removed after the trailing fabric has been severed as will be hereinafter more fully described.
The cutter track 27 includes a box girder 29 extending transversely between the frames 5,5 and tilted 45 about its longitudinal axis. The upper face of the girder is slotted to receive a pair of angle bars 30,30 having spaced parallel outwardly projecting flanges 31,31 which together define a fabric-tensioning rail. A fabric cutter, generally indicated 32,
is adapted to be manually reciprocated along the cutter track 27 and includes a central supporting plate 33 provided at its right end (as view in FIG. 6) with a generally V-shaped throat 34, the vee of which is coplanar with the outer edges of the flanges 31. A cutting blade 35 is removable clamped to the plate 33 adjacent to the vee of the throat 34. The plate 33 rotatably carries two sets of outer wheels 36,36 which span the flanges 31,31 and two sets of inner wheels 37,37 adapted to engage the inner face of the associated slotted web of the box girder 29. A handle'38 extends upwardly from the plate 33 for operation of the cutter.
The initial position of the cutter 32 is at the extreme left, as viewed in FIG. 1 of the drawings in order to provide clearance for the rolled fabric batch to pass over the cutter track 27 without obstruction. After the rolled batch has been received by the trough 28, the cutter is manually moved to the right and the throat 34 thereof receives the edge of the fabric to be cut. As the cutter progresses to the right the outer wheels 36 thereof stretch the fabric around the flanges 31,31 so that the blade 35 may readily and cleanly cut the fabric. When the cutter reaches the far edge of the fabric, an abutment 39 carried by the cutter contacts an actuating lever 40 of a microswitch 41 mounted on the right hand clamp 16 to actuate a solenoid valve (not shown) to release an air blast from a pipe 42 to blow the freely severed end of the fabric up onto the newly positioned empty core on the winding rolls 6,6 and to simultaneously restart the rolls 6 through the clutch 8. Then the cutter 32 is returned to its initial position at the left end of the track 27.
In the meantime, a continuously driven draw roll 43. having a peripheral speed equal to the linear discharge speed of the fabric from the associated processing unit, keeps feeding the fabric toward the batcher. When the winder rolls 6,6 are stopped the fabric drops into a loop as indicated in dotted lines at 44, and if this loop should become too large, the slack may be taken up by temporarily disengaging the clutch 8 and engaging the clutch which operates a higher speed drive for the rolls 6,6.
It is of course to be understood that variations in arrangement and proportions of parts may be made within the scope of the appended claims.
