(Cl. 57-34) ABSTRACT OF THE DISCLOSURE A combination spinning or twinin and cheese winding fiber processing machine is provided. The spindles of the fiber processing machine are divided into two groups carried by spindle mounting means in the spinning apparatus. Those of one group lie in bobbin winding positions in the spinning apparatus while those of the other group lie in cheese winding positions of the combined machine. Means is provided for moving the cheese winding apparatus along the frame of the machine and for delivering to it to be wound into a cheese yarn drawn from the bobbins located in the cheese winding positions Without removal of the bobbins from the spindles carried by the spindle mounting means of the spinning apparatus.

This invention relates to an apparatus for forming cheeses by the direct winding of full bobbins without doffing operation in fiber processing machines such as spinning frames and twisting machines.

Generally, in spinning frames or twisting machines (hereinafter referred to as fiber processing machines), full bobbins are first dotfed from the spindles and then placed on an automatic winder (hereinafter referred to as automatic winding machine) for forming cheeses. Thus, much time and labor and required for this dofling operation. Further, in order to place full bobbins on the automatic dotfing machine, it is require-d to transport the full bobbins to such machine. It is also required to insert the full bobbins one by one onto the spindles of the automatic winding machine, which requires further time and labor. Moreover, in the known system, fiber processing machines and automatic winding machines are separately installed, so that much space is required, with the increased cost of installation. 1

Another system recently developed is known wherein an automatic winding machine is arranged to be movable in front of and along a fiber processing machine, and besides the ring rails inherent to the fiber processing machine, exchange rails are additionally provided for inserting full bobbins thereinto, whereby yarns on the full bobbins on said exchange rails are wound into cheeses by the automatic winding machine moving along the fiber processing machine. However, this system only incorporates an automatic winding machine into a fiber processing machine with the view to decreasing the floor space required for installation of the automatic winding machine and the labor of transportation of full bobbins. Thus, full bobbins on the side of the spindle rails as produced by the twisting and winding operation of the fiber processing machine still have to be removed to the exchange rails either manually or by an expensive and complicated automatic bobbin exchanger. Thus, the problem of bobbin exchange is left unsettled, still requiring labor or troublesome automatic bobbin exchangers.

The present invention eliminates the aforesaid drawbacks and provides improvements wherein a large number of spindles mounted on the spindle rails on a fiber 3,391,527 Patented July 9, 1968 processing machine are divided into two groups, each spindle group being in exchangeable relation to the other so as to be capable of being positioned either in the drafting, twisting and winding regions or twisting and windin regions or in the cheese winding regions of the fiber processing machine, the latter machine performing its drafting, twisting and winding operation or twisting and winding operation on the empty bobbins of the spindle group positioned in said drafting, twisting and Windi g or twisting and winding regions, the full bobbins of the other spindle group being treated, without being dofifed, by an automatic winding machine travelling in front of and along the fiber processing machine for forming cheeses, it being so arranged that when the bobbins of one spindle group positioned in the drafting, twisting and winding regions or twisting and winding regions have become full, the yarns on the full bobbins of the other spindle group have also been completely wound into cheeses, whereupon the two spindle groups are exchanged at a time, the aforesaid operations being then repeated.

Since the invention is thus arranged, it is possible to omit the convention-ally indispensable dofiing operation and preclude the necessity of transporting full bobbins to automatic winding machines, hereby saving time and labor heretofore required for dofiing operation, and eliminating the use of complicated automatic bobbin exchanger. Hence the invention can promote the efiiciency of textile operation. K

On the premise that yarn knotting operation can be automatically carried out if use is made of a full automatic winding machine and that the time required for said winding machine to wind the yarn of one full bobbin into a cheese is much less than the time required for completing one full bobbin, it is possible to set the treating power of the automatic winding machine, i.e., the number of the full bobbins which it can treat to form cheeses during the time required for completing one full bobbin, so that if the full automatic winding machine is allowed to run step by step so as to treat said set number of full bobbins in a predetermined time, cheeses can be continually produced one by one each time after either one group of spindles have completed the formation of full bobbins once or twice.

In order to decrease the number of dofling and donning operations and of operators, there has heretofore been a tendency to increase the amount of yarn per bobbin. According to the present invention, it is no longer necessary to take the trouble to produce such increased full bobbins, since no operator is required for dofling and donning operations. As a matter of course, the diameter of the rings of fiber processing machines can be decreased as well as the lift, so that by frequently repeating the formation of small full bobbins, it is possible to speed up fiber processing machines to promote the efiiciency of textile operation.

Moreover, according to the invention the promotion of the efliciency of textile operation is further assisted by the fact that the drafting, twisting and winding operation effected by fiber processing machines and the cheese Winding operation effected by automatic winding machines can be concurrently and repeatedly carried out.

Further, according to the invention, without the need of exchanging bobbins on the side of fiber processing machines and automatic Winding machines, the same effect of bobbin exchange as before can be expected simply by exchanging the positions of two spindle groups at a predetermined time. Consequently, the troublesome bobbin exchange can be entirely avoided.

The invention will now be described with reference to the accompanying drawings. Although the following description is given with reference to an instance in which the invention is applied to a spinning frame, a similar construction may be made in accordance with the invention in case of a twisting machine.

FIG. 16 is a view similar to FIG. 15, but showing a modification thereof.

Referring to the drawings, in FIG. 1 is shown a method of dividing a number of spindles into two groups and alternately positioning the thus grouped spindles in drafting and winding sections corresponding to draft roller mechanisms and in cheese winding sections operated by automatic winding machines. In other Words, a number of spindles 2 laterally disposed on a frame 1 are divided into a first group of spindle 2 in odd numbers and a second group of spindles 2" in even numbers. The odd numbered and even-

numbered spindles

2, 2" are separately driven by drive shafts 3, 3', respectively, journalled in parallel to the frame. It will be noted that in such a kind of spinning frame, spindles are arranged correspondingly to each other on both sides of the frame 1. Thus, spindles in odd or even numbers on one side are associated in pairs with those in odd or even numbers on the other side. Such pairs can be divided into two groups in connection with different power sources by drivingly associating them with respective drive shafts 3, 3' as by tapes 4, 4', as shown in FIGS. 1 and 2. The draft roller mechanisms 5 of the spinning frame are of known construction, and are mounted on the spinning frame members F with twice the spindle pitch, i.e. as shown in FIG. I the draft rollers 5 are spaced twice as far apart as the adjacent spindles 2' and 2". It is necessary that these draft roller mechanisms be so arranged on the frame F as. to correspond to either the even-numbered or the odd-numbered spindle group carried by frame 1. These two spindle groups 2' and 2", their two drive shafts 3, 3', and the clutches and power source to be later described are so constructed that they may be integrally moved a half the roller pitch either to the right or to the left at the predetermined time by movement of frame 1 on which they are mounted relative to frame members F on which the rollers 5 are mounted, by any suitable means (not shown). Further, these two drive shafts 3 and 3 are connected to a single power source (not shown) through clutches for the change of drive (not shown). The change of drive is such that when one drive for a first spindle group which now confronts or corresponds to the draft roller mechanisms is being driven, the other drive shaft for the other or second spindle group which now confronts or corresponds to the cheese winding regions is in disengagement from the power source. Thus, the spindle group corresponding to the draft roller mechanisms is rotated at a high speed, thereby allowing the spindles to effect the usual drafting and spinning operation in cooperation with the draft roller mechanisms, while the other spindle group deviated from said draft roller mechanisms is in a stationary condition and hence the yarns on the full bob-bins on these spindles are stationary so that they will be successively wound into cheeses by means of automatic winding machines travelling stepwise along the spinning frame.

In this spinning frame embodying the invention wherein spindles arranged in rows are divided into two groups by the relation of odd and even numbers, the object of simultaneously effecting the drafting and winding operation and the cheese winding operation requiresthe provision of a ring rail which is different from known one. That is to say, for drafting and winding, it is necessary to raise and lower spindle rails along bobbins. On the other hand, at the cheese winding regions adjacent the draft roller mechanisms, such ring rail constitutes an obstacle, which is required to be removed. Thus, the ring rails used herein should be of such a structure as to meet the above-mentioned conditions. One such statisfactory form of ring rail 6 is shown in FIGS. 1 and 4. As shown, it is composed of a ring rail base body 6' disposed inside the spindle rows to extend along the full length of the frame and vertically movable, and ring support plates 6" outwardly projecting therefrom to correspond to the draft roller mechanisms. The ring support plates 6" are fitted with rings 7 including travellers. With the arrangement thus made, it is possible to effect the building motion of the ring rails at the draft roller mechanism and simultaneously effect the two distinct operations, i.e. a drafting, twisting and winding operation and a cheese winding operation, with the spindles of the two groups maintained in a row on either side.

In FIG. 3 the left half shows the drafting, twisting and winding regions operated by the roller draft mechanism while the right half shows the cheese winding regions operated by the automatic winding machines. In such drafting, twisting and winding regions it is required to provide means for separating yarns connected to full bobbins therefrom when the two spindle groups are to be exchanged and for winding the thus separated yarns extending from the draft roller mechanisms around their respective empty bobbins newly supplied to the drafting, twisting and winding regions.

The means will now be explained. As shown in FIGS. 3, 4 and 5, each drafting, twisting and winding region is provided with an arm body 11 adapted to press down a spun yarn 9 to press down a spun yarn 9 to cause the latter to cross a yarn gripper body 10. Such arm bodies are secured to a common shaft 12 in such a manner that they may correspond to their respective drafting, twisting and winding regions and be positioned somewhat laterally of the spindles. A rod 13 is provided at the free end of each arm body so as to cross said spun yarn for pressing down the latter upon the falling-down of the arm body.

The yarn gripper 10, which serves to temporarily grip the spun yarns pressed down by the arm bodies, is so mounted that it is positioned in front of the spindles and somewhat below yarn holder bodies 14 rigidly secured to the spindles. The yarn gripper body 10 is in the form of an elongated bar extending along the full length of the frame and is composed of fixed and movable rods 10' and 10", respectively, contacted with each other at their side surfaces and adapted to be shiftable to change their relative position, as shown in FIGS. 6 and 7. Further, it is provided with

recesses

15 and 15 on the upper surfaces of both rods at the places thereof corresponding to the drafting, twisting and winding regions. Blocks 16 are fitted in said recesses to stride the latter, said blocks being rigidly secured to the movable rod by means of bolts 17. FIG. 6 shows a condition in which the spun yarn is not gripped, while FIG. 7 shows another condition in which it is gripped. Though not shown in FIGS. 6 and 7, guide

plates

18, 18 for spun yarns are rigidly secured to the fixed rod of the yarn gripper body 10, on both sides of the recesses, as shown in FIGS. 4 and 5, in order that the spun yarns, when pressed down by the arm bodies, may be positively guided to cross the recesses of the yarn gripper body. Yarn transfer bodies 19 which serve to cause the spun yarns extending between the yarn gripper body and the draft roller mechanisms to be seized by empty bobbins are provided in front of the yarn gripper body. These yarn transfer bodies are mounted on a transverse rod 20 extending along the full length of the frame so as to correspond to the drafting, twisting and winding regions and are normally held in a condition shown in solid lines in FIGS. 3 and 4. The transverse rods are supported by and between two arm bodies 21 having their root portions pivoted to the frame. Thus, when the yarn gripper body 10 grips the spun yarns and new bobbins are supplied to the drafting, twisting and Winding regions, the yarn transfer bodies are swung forwardly by the swing movement of the arm bodies 21, thereby supplying the spun yarns connected between the yarn gripper body and the draft roller mechanisms to the yarn holder bodies 14 at the roots of the spindles. The structure of such yarn holder body rigidly secured to the root of a spindle is shown in FIGS. 8 and 9. It consists of a circular plate 24 having a hub sleeve 22 to be rigidly secured to the root of a spindle and two or three grooves 23 equispaced on the surface. These grooves are so arranged as to extend in the direction of the rotation of the circular plate, and receive therein the front ends 25 of plate springs 25 as shown in FIGS. 10. The roots of the plate springs are rigidly secured to the peripheral upright edge of the circular plate. Thus, the spun yarn can be held between the front end 25' of the plate spring and the inner wall 23' of the grooves.

The operation of the present invention is as follows.

When the drafting, twisting and winding operation of one group of spindles is completed to provide full bobbins in a condition shown on the left-hand side of FIG. 3, the ring rails are lowered at a high speed to the lowermost level as shown in FIG. 5, and the spun yarns are wound two or three turns around the lower portions of the full bobbins, whereupon the group of spindles are simultaneously stopped. At this time, the cheese winding operation shown on the right-hand side of FIG. 3 has just been completed also. Thereafter, the ring rails are raised at a high speed to a position free from interfering with the successive operations, i.e., a position shown in dot and dash lines in FIG. 3. After the ring rails have been raised to the predetermined level, the arm bodies fall down to a position shown in dot and dash lines in FIGS. 3 and 5, thereby causing the spun yarns to cross the recess of the yarn gripper body. Simultaneously therewith, the yarn gripper body is actuated to grip the crossing portions of the spun yarns as shown in FIG. 7. In this condition the group of spindles carrying thereon full bobbins are simultaneously rotated one or two turns thereby cutting off the spun yarns between the yarn gripper body and spindles. In so doing, the arm bodies 11 are returned to the solid line position shown in FIG. 3. Upon the completion of the cutting of the spun yarns, the two spindle groups are simultaneously moved in a predetermined direction by /2 roller pitch, so that the full bobbin-carrying spindles are positioned in the adjacent cheese winding regions, while the empty bobbins which were positioned in the cheese winding regions are now positioned in the drafting, twisting and winding regions. That is to say, the two spindle groups exchange their positions. In this condition the yarn transfer bodies in front of the yarn gripper body advance towards the corresponding spindles thereby to press down the spun yarns connected between the yarn holder bodies and the draft roller mechanisms against the lower portions of the yarn holder bodies below the spindles, and then said group of spindles are simultaneously rotated one or two turns, whereupon the yarns are inserted into the grooves of the yarn holder bodies which, in turn, positively grip the spun yarns. At the same time, the spun yarns are released from the yarn gripper body, and then the ring rails are again lowered to the lowermost position, whereupon the group of spindles in the drafting, twisting and winding regions are simultaneously driven, so that the next drafting and spinning operation is started. Concurrently with the drafting, twisting and winding operation, the automatic winding machines associated with the frame begin cheese winding operation. In addition, on either side of the frame are provided rails 27 and 28 extending along the full length of the frame for the auto matic winding machines 26, as shown in FIG. 3.

Now, the reason why a series of drafting-winding and cheese winding can be smoothly effected by such concurrent operations, namely, drafting, twisting and winding operation effected by the spinning frame and cheese winding operation effected by the automatic cheese winding machine, will be described by showing an example. Supposing, for example, that the yarn delivery speed of the spinning frame is 30 m./min. and the winding speed of the automatic winding machines is 800 m./min., it suffices that one automatic cheese winding machine has charge of full bobbins, about 24 in number calculated as an approximate value of 800/30. On the other hand, the Weight of a cheese is generally of the order of 1.8 pounds. Thus, if the amount of the yarn on a full bobbin is adjusted to about 0.037 pound, it is possible to produce one cheese from 48 full bobbins. That is to say, it is possible to produce one cheese by allowing an automatic winding machine to execute one reciprocation per 24 spindles. Therefore, it is seen that it suffices for this purpose to provide such automatic winding machines on either side of the frame with a ratio of one machine per 24 spindles. It is to be understood that the numerical values given above are only by way of example, and that other various combinations may be obtained as desired based upon the aforesaid principle by suitably determining the weight of one cheese and the amount of the yarn on one full bobbin. 7

FIG. 11 shows another embodiment of the invention, wherein two spindle groups 29 and 30 are adapted to be driven by a single tape 31. Thus, of the spindles arranged in a row, those located at odd numbers form one group and those located at even numbers form the other group, the exchange of the positions of said spindle groups being effected in the same manner as the first embodiment by simultaneously shifting all spindles a half the roller pitch in one direction. Thereafter, the spindle group which is deviated from draft roller mechanisms 32 will be somewhat tilted outwardly away from the tape. This tilting mechanism will be described with reference to FIG. 12. Plates 54 each supporting a spindle are arranged on the frame, said support plates being hinged at 55 so that they may be tilted relative to the frame at a predetermined time. Fixedly positioned below the front end portions of these support plates is a cam plate 56 provided with raised portions 56' at the places thereof confronting the draft roller mechanisms. Thus, those support plates which ride on said raised portions are in lifted position as shown in FIG. 12, so that the spindles supported thereby are in drafting, twisting and winding condition and the spindle wharves are, of course, in contact with the tape, which is supported for driving the spindles, as aforesaid, by any suitable tape supporting means (not shown) e.g. of the known form shown in DAS 1,066,112 published by the German Patent Ofiice Sept. 24, 1959. On the other hand, the other support plates positioned in the cheese winding regions are forwardly tilted against the recesses 56" of the cam plate, so that the corresponding spindle wharves are out of contact with the tape and in stopped position. In this condition, cheese winding operation is carried out. It will be seen that if the base member on which are mounted these support plates is moved by A2 roller pitch, the as-raised and as-lowered support plates will be lowered and raised by the recesses and raised portions of the cam plate, all respectively. In short, the group of spindles confronting the draft roller mechanisms are contacted with the tape, are rotated at a high speed, and perform the intended drafting and spinning operation in cooperation with the draft roller mechanisms, while the other spindles are in stopped position so that the yarns on the full bobbins carried by these stopped spindles are Wound into cheeses by the automatic winding machines. The other arrangements of this embodiment are the same as the first embodiment.

FIGS. 13 through 16 show a further embodiment, wherein spindles are arranged in two rows, front and rear, on each side of the frame, said front and rear rows each forming one group. After the lapse of the predetermined time, the pairs of spindles are simultaneously to tated through 180 whereby the positions of the two groups of spindles are exchanged. This will be described in more detail with reference to FIGS. 13 through 16.

Spindles

33 and 34 are arranged in two rows on each side of the frame, the outer spindle group 33 being posi- 1 tioned on the cheese winding region side, the inner spindle group 34 being in a position to cooperate with the draft roller mechanism 35, all the spindles of the group 34 being in contact with a single tape 36 and driven at a high speed. This will be further described with reference to FIG. 14. A spindle rail 37 is provided with as many bearing sleeves 38 as the spindles of one group vertically extending therefrom and arranged at fixed intervals. Shafts 40 for spindle support plates 39 are rotatably fitted in said bearing sleeves. The spindle support plates are in the form of elongated plates having said shafts secured to the middle portions of the lower surfaces thereof and are supported on the upper surfaces of the bearing sleeves. Pairs of bolsters 41, 42 are secured to the spindle support plates at their opposed end portions equidistant from the axes of the shafts 40, each pair receiving therein a pair of spindles. The spindle support plates are so placed that these pairs of spindles may be positioned in front and rear relation as shown in the figure. That is to say, two spindle rows, front and rear, are provided on the spindle rail. In this condition the spinning frame is run to wind spun yarns 43 onto bobbins 44. When the bobbins become full, the machine is stopped, whereupon the spindle support plates are turned through 180, thereby effecting the positional exchange between the full bobbins in rear row and empty bobbins in front row. This means that the full bobbins assume the front row position and the empty bobbins assume the rear row position to cooperate with the draft roller mechanisms. In these conditions, spinning and winding operation is again effected at rear row and concurrently therewith the automatic winding machines provided in front of the spinning frame draw yarns from the full bobbins in front row and wind them into cheeses. Each of the shafts of the spindle support plates has a worm wheel 45 secured to the lower end thereof. These worm wheels mesh with corresponding worms 47 mounted on a common shaft 46. Thus, by rotating the common shaft, all the spindle support plates are rotated through 180 to exchange the positions of the front and rear spindle rows at a time. In this case, if it is so arranged that all the spindle support plates are rotated at a time, it will be apparent from FIG. 15 that the distance between each pair of spindles must be relatively long. For the purpose of decreasing such distance, it may be so arranged that half the spindle support plates, positioned at every second place, are simultaneously rotated by like worms 47A carried by a common shaft 46A, followed by the next simultaneous rotation of the other by like worms 47B carried by a common shaft 4613, thereby completing the positional exchange of the front and rear rows at two times, as shown in FIG. 16. With this arrangement, the spindle distance can be shortened. In addition, in effecting the positional exchange of the two groups, the above-mentioned third embodiment also must be provided with means for cutting the spun yarns off their full bobbins and winding the thus separated yarns around the empty bobbins supplied to the drafting, twisting and winding regions. Unlike the first embodiment, in this case the arm bodies for pressing down yarns are positioned in front of the spindles, while the yarn gripper body and yarn transfer bodies are positioned at the rear of the spindles. With this arrangement, it is possible to smoothly perform the procedures at the time of the bobbin exchange in the same manner as the first embodiment.

In addition, in the drawings, 48 designates a sliver bobbin; 49, 50 snail wires; 51 the dram of the automatic winding machine; 52 a cradle; and 53 a cheese.
