Definitions

  • the present invention relates mainly to a side plate provided in a draft device.
  • a draft device in a spinning machine appropriate drafting may be prevented by an increased amount of floating fibers having failed to be nipped by draft rollers.
  • an appropriate arrangement distance (gauge) needs to be set between the draft rollers.
  • the gauge between the draft rollers to be set varies depending on, for example, the type or application of fibers to be spun.
  • a side plate is conventionally used to position the plurality of draft rollers in the draft device.
  • a side plate of this kind is disclosed in, for example, the Unexamined Japanese Utility Model Application Publication ( Jikkai-Hei) No. 4-123268 .
  • the Unexamined Japanese Utility Model Application Publication ( Jikkai-Hei) No. 4-123268 discloses a gauge adjusting mechanism configured as described below. That is, the gauge adjusting mechanism has roller shaft support members that individually support roller shafts of top rollers positioned behind a second top roller around which an apron band is installed.
  • the roller shaft support members are movably mounted to a side plate of a cradle.
  • the gauge between the rollers can be adjustably changed by moving the roller shaft support members forward and backward with respect to the draft device.
  • this configuration makes it possible to adjust the gauge to a desired value to eliminate the need to prepare various side plates. This also eliminates the need to replace the side plate with a different one and mount the different side plate again every time the gauge is changed.
  • the support member for the gauge adjusting mechanism is movably mounted to the side plate with slits and screws. Consequently, to accurately place the draft rollers at positions where the desired gauge is set in order to prevent possible uneven drafting, the support members must be screwed shut with the positions of the support members precisely adjusted within the range of the size of the slit. Therefore, a gauge changing and fine-tuning operation is complicated and requires a substantially long time and substantially much man-hour.
  • the gauge is changed in each of a large number of spinning units.
  • an object of the present invention is to provide a side plate which enables a reduction in costs and which allows gauges to be easily and reliably adjusted.
  • a first aspect of the present invention provides the following configuration of a side plate used to position a plurality of draft rollers in a draft device. That is, the side plate comprises a fixed mennber and a movable member.
  • the fixed member comprises roller support portions that support the draft rollers, and the fixed member is mounted to the draft device at a fixed position.
  • the movable member comprises roller support portions that support the draft rollers, and a position of the movable member with respect to the draft device is changeable within a predetermined stroke.
  • a preset first pitch is provided between the draft roller on the fixed member side and the draft roller on the movable member side.
  • a preset second pitch different from the first pitch is provided between the draft roller on the fixed member side and the draft roller on the movable member side.
  • the gauge between the draft roller on the fixed member side and the draft roller on the movable member side can be easily changed by changing the mounting position of the movable member between the first end and second end of the stroke range. Furthermore, the first pitch or the second pitch can be accurately provided by positioning the movable member at the first end or second end of the stroke range. Thus, the operation of fine-tuning the position of the movable member need not be performed. This also facilitates the gauge changing operation. Furthermore, the gauge can be adjusted without the need to remove the draft rollers from the roller support portions of the fixed member and the movable member. Therefore, the effort and time required for the gauge changing operation can be reduced.
  • the movable member comprises a plurality of roller support portions, and moving the movable member integrally moves the plurality of roller support portions.
  • the side plate is preferably configured such that with the fixed member fixed to the draft device, the movable member is replaceable with another movable member having roller support portions arranged at a distance from each other which is different from the distance between the roller support portions of the first movable member.
  • the gauge changing operation can be efficiently performed.
  • the gauge can be changed to any of various values simply by moving and replacing the movable member with a different one with the fixed member remaining unchanged. This enables a reduction in the manufacturing costs of the side plate.
  • the movable member has an abutting surface that contacts with the fixed member to position the movable member at the appropriate end of the stroke range.
  • the first pitch and the second pitch can be reproducively obtained using the simple configuration.
  • a slot or a groove is formed in at least one of the fixed member and the movable member, and an end of the slot or groove is used to position the movable member at the appropriate end of the stroke range.
  • the first pitch and the second pitch can be reproducively obtained using the simple configuration.
  • the movable member comprises a slot having one open end, and the movable member is mounted to the draft device or the fixed member with a shaft portion of a mounting member inserted through the slot.
  • the movable member can be removed from the draft device without the need to remove the mounting member. Consequently, the operation of attaching/removing the mounting member can be omitted, facilitating the operation of replacing the movable member with a different one.
  • the side plate preferably has the following configuration. That is, the fixed member comprises a reference display portion, and the movable member comprises two position display portions. When the movable member is positioned at one of the ends of the stroke range, the reference display portion aligns with one of the two position display portions.
  • reading the reference display portion and the position display portions makes it possible to easily determine whether or not the movable member is reliably positioned at the appropriate end of the stroke range.
  • the first pitch and the second pitch are displayed close to the respective position display portions as numbers.
  • This configuration makes it possible to easily determine which gauge has been provided between the draft roller on the fixed member side and the draft roller on the movable member side.
  • a second aspect of the present invention provides a draft device comprising the side plate and a textile machine comprising the draft device.
  • Figure 1 shows a spinning machine 1 serving as a textile machine and comprising a large number of juxtaposed spinning units (yarn processing units) 2.
  • each of the spinning units 2 has a draft device 7, a spinning device 9, a yarn feeding device 11, and a winding device 12 as main components.
  • the spinning unit 2 is configured such that the draft device 7 is provided near an upper end of a casing 6 of the spinning machine 1 main body so that a fiber bundle 8 fed from the draft device 7 is spun by the spinning device 9.
  • a spun yarn 10 discharged by the spinning device 9 is fed downward by the yarn feeding device 11.
  • the spun yarn 10 then passes through a clearer (yarn defect detector) 52 which detects a defect in the yarn and which cuts the defective yarn to remove the defective yarn part.
  • the spun yarn 10 is then wound by the winding device 12 to form a package 45.
  • the spinning machine 1 is equipped with a blower box 80 and a motor box 81. Furthermore, although not shown in the figure, the spinning machine 1 comprise a yarn splicing vehicle provided so as to travelable in a direction in which the spinning units 2 are arranged and a doffing vehicle provided so as to be travelable independently of the yarn splicing vehicle.
  • FIG. 2 shows an enlarged side view of the draft device 7, the spinning device 9, and the yarn feeding device 11.
  • the draft device 7 comprises a draft roller that draws a sliver 13 into a fiber bundle 8.
  • the draft roller is composed of a top roller and a bottom roller arranged opposite each other.
  • the top roller is composed of four rollers, that is, a back roller 14, a third roller 15, a middle roller 16 around which an apron belt 17 is installed, and a front roller 18. These top rollers 14, 15, 16, 18 are mounted to a cover-like cradle 20 provided in the draft device 7.
  • a bottom roller is composed of four rollers, a back bottom roller 24, a third bottom roller 25, a middle roller 26 around which an apron belt 27 is installed, and a front bottom roller 28.
  • the bottom rollers 24, 25, 26, 28 are mounted to the draft device 7 main body and arranged opposite the top rollers 14, 15, 16, 18.
  • a spring box (not shown in the drawings) is provided inside the cradle 20 to bias the top rollers 14, 15, 16, 18 so as to press the top rollers 14, 15, 16, 18 against the bottom rollers 24, 25, 26, 28. This allows the sliver 13 to be nipped between the top rollers 14, 15, 16, 18 and the bottom rollers 24, 25, 26, 28.
  • the respective top rollers 14, 15, 16, 18 are positioned by a side plate 70 mounted to a side surface of the cradle 20. This sets the distances (gauges) between the nip points of the top rollers 14, 15, 16, 18 for the sliver to predetermined values.
  • Each of the cradles 20 is provided for two spinning units 2 as shown in Figure 2 , and the side plate 70 is mounted to each of the opposite surfaces of the cradle 20. The details of the configuration of the side plate 70 will be described below.
  • the sliver 13 fed to the draft device 7 is drawn by the draft rollers, rotationally driven at different speeds, and is thus formed into the fiber bundle 8, which is then fed to the spinning device 9, as shown in Figure 2 .
  • the spinning device 9 pneumatically spins the fiber bundle 8 fed from the draft device 7.
  • the pneumatically spun fiber bundle 8 is fed to the yarn feeding device 11 as the spun yarn 10.
  • the yarn feeding device 11 comprises a delivery roller 39 supported by the casing of the spinning machine 1 main body and a nip roller 40 provided so as to freely contact and leave the delivery roller 39.
  • the spun yarn 10 discharged by the spinning device 9 is sandwiched between the delivery roller 39 and the nip roller 40, and the delivery roller 39 is then rotationally driven.
  • the spun yarn 10 can thus be fed to the winding device 12.
  • the cradle 20 is provided so as to be pivotable around a pivoting shaft portion 29 with respect to the draft device 7. Furthermore, a cradle handle 23 is fixed to the cradle 20. In this configuration, while the spinning machine 1 is in operation, the cradle 20 is in the position shown in Figure 2 and is locked by a lock mechanism (not shown in the drawings). The cradle 20 is opened by unlocking the lock mechanism and raising the cradle handle 23. In this condition, the following operations are performed: a maintenance operation including replacement of the top roller 14, 15, 16, 18 or the bottom roller 24, 25, 26, 28, an operation of adjusting the gauge between the draft rollers as described below, and the like.
  • FIG. 3 shows a diagram of the entire side plate 70 according to one embodiment of the present invention.
  • the side plate 70 is divided into a front member (fixed member) 21 and a back member (movable member) 22.
  • Each of the front member 21 and the back member 22 is made of metal and formed like a plate having a predetermined thickness.
  • the front member 21 comprises a front roller support portion 78 that supports the front roller 18 and a middle roller support portion 76 that supports the middle roller 16.
  • the back member 22 comprises a third roller support portion 75 that supports the third roller 15 and a back roller support portion 74 that supports the back roller 14.
  • the roller support portions 74, 75, 76, 78 have recess portions respectively.
  • the top rollers 14, 15, 16, 18 can be positioned by positioning and supporting bearing portions of the respective top rollers 14, 15, 16, 18 in the recess portions.
  • the front roller support portion 78 and the middle roller support portion 76 are both formed in the front member 21. Consequently, the gauge between the front roller 18 and the middle roller 16 is unchangeable.
  • the third roller support portion 75 and the roller support portion 74 are both formed in the back member 22. Consequently, the gauge between the third roller 15 and the back roller 14 is unchangeable.
  • the positions of the roller support portions 74, 75, 76, 78 are such that the gauge between the front roller 18 and the middle roller 16, and the gauge between the third roller 15 and the back roller 14 are set equal to preset predetermined distances.
  • plural types of back member 22 are manufactured and prepared which have different gauges between the third roller 15 and the back roller 14.
  • Circular penetrating mounting holes 69, 69 are formed in the front member 21 of the side plate 70.
  • the front member 21 is mounted to the cradle 20 by threadably inserting screws 91, 92 through the mounting holes 69, 69 (see Figure 4 ).
  • the threadable insertion of the screws immovably fixes the side plate 70 to the cradle 20. Consequently, the front roller support portion 78 and the middle roller support portion 76 are fixed and the positions thereof are unchangeable.
  • a notch portion 63 and a slot portion 61 are formed in the back member 22 of the side plate 70.
  • the notch portion 63 and the slot portion 61 are formed to be elongate along a direction in which the roller support portions 74, 75, 76, 78 are arranged (the direction in which the sliver 13 travels).

  • An inner portion of the cradle 20 is padded at the positions of the internally threaded holes by welding or the like to so as to offer an appropriate strength.
  • the back member 22 can be moved within a predetermined stroke range along the notch portion 63 and the slot portion 61 by loosening the screws 93, 94 ( Figure 4 ) for mounting. This means that the gauge between the middle roller 16 and the third roller 15 can be changed with the gauge between the front roller 18 and the middle roller 16, and the gauge between the third roller 15 and the back roller 14 maintained constant.
  • the position of the roller support portions 74, 75, 76, 78 and the position of the abutting surface of the abutting portion 62, and the like are set such that in the condition in Figure 4 , in which the back member 22 is positioned at the first end of the stroke range, a preset first pitch (gauge) P1 is provided between the middle roller 16 and the third roller 15.
