Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present application, the web supplied from the feeding unit is converged by a web concentrator, and the converged sliver is sequentially sent to the calendar roller and the draft roller, and the sliver unevenness measured upstream of the draft roller is drafted. The present invention relates to a card machine in which sliver unevenness is removed by controlling the speed change of rollers.

[0002]

[Prior art]

 A card machine that controls the sliver unevenness as described above is conventionally a card machine that is close to the downstream side of the delivery section, which is generally composed of a doffer and a delivery roller, and the web concentrator and the upper and lower calendar rollers are close to the delivery section and cannot be separated from each other. The card machine base is provided with at least a pair of upper and lower variable draft rollers downstream of the calendar roller so as not to come close to or separate from the sending portion.

[0003]

[Problems to be solved by the device]

 In the above card machine, the web concentrator, the calendar roller, and the draft roller are provided on the card machine base so as not to come close to or separate from the feeding portion, so that the sliver is spliced or the sliver immediately after passing the web concentrator is passed. During operations such as when observing the condition, a sufficient working space cannot be formed between the feeding section and the web concentrator, and there is a problem that these operations are difficult.

On the other hand, in Japanese Patent Laid-Open No. 57-95315, a web focusing device and a calendar roller are attached to a support (housing), and the support is attached to a card machine stand so as to approach and separate from a delivery mechanism. Some are provided. Considering the case where the technique of Japanese Patent Laid-Open No. 57-95315 is applied to a card machine having the draft roller, at the time of work, the support is largely separated from the delivery section to thereby provide a delivery section and a web converging device. The above work can be performed easily because a sufficient working space is formed between the draft roller and the calendar roller provided on the support body when the support body is located far away from the feeding section. The calendar roller is placed on the card stand so that there is sufficient movement space between the draft roller and the calendar roller so that the support roller does not interfere with the feeding roller. There was a drawback that the device for the web focusing part including it became large.

From the above, the object of the present application is to provide a card for controlling draft unevenness on the downstream side of the feeding section, which can form a sufficient working space between the feeding section and the web converging device at the time of work and can also be used for the web converging section. It is to provide a card machine that can be miniaturized.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present application, a web concentrator, a pair of upper and lower calendar rollers and a draft roller are sequentially arranged on the downstream side of the feeding section including the doffer and the feeding roller, and the measurement is performed on the upstream side of the draft roller. In a card machine in which the draft roller is rotated at variable speed according to the unevenness of the sliver to remove the unevenness of the sliver, the web focusing device, the calendar roller, and the draft roller are attached to a support, and the support is It is characterized in that it is mounted on the card machine base so as to come close to and separate from the approaching position close to the sending-out part and the separating position far from it.

[0007]

[Action]

 During normal operation of the card machine, the support is brought close to the feeding section, and the web fed from the feeding section travels a short distance to the web concentrator and is converged on the sliver by the web concentrator. Further, the bundled sliver is sent to a calender roller and a draft roller, and for example, the calender roller portion detects the thickness of the sliver, and the draft roller is shifted depending on the size of the sliver unevenness, so that the sliver unevenness is removed. . Further, at the time of work, the support is moved away from the sending-out portion, and a sufficient working space is formed between the sending-out portion and the weight concentrator, so that the work can be performed easily.

As shown in FIG. 3, a roller shaft 33 is rotatably supported via a bearing 32 in a shaft support hole 31 formed in the calendar roller support block 27. At the center of the roller shaft 33, a lower calendar roller 34 having a length substantially the same as that between the left and right support blocks 27 is keyed. A groove 36 into which a convex portion 37 of an upper calendar roller 35 described later is fitted is formed in the central portion of the outer periphery of the lower calendar roller 34. A pulley 38 is fixed to the right end portion of the roller shaft 33, and a belt 40 is wound around the pulley 38 and the pulley 39 fixed to the drive shaft 23 so that the rotation of the drive shaft 23 can be prevented by the roller shaft. It is designed to be transmitted to 33.

As shown in FIG. 2, a pair of left and right support walls 43 are juxtaposed on the upper surface of each of the left and right calendar roller support blocks 27. A fixed shaft 44 is fixed to the support wall 43, and a base end of a swing arm 46 is swingably supported on an end of the fixed shaft 44 via a bearing 45. A roller shaft 47 is installed between the left and right swing arms 46, and a convex portion 37 is formed in the central portion of the roller shaft 47 via a bearing 48 in the central portion of the roller shaft 47, as shown in FIG. A roller 35 is rotatably supported.

Further, as shown in FIG. 1, a loose fitting hole 52 into which the pressure bolt 51 is loosely fitted is formed at the tip of each swing arm 46, and the pressure bolt 51 has a lower screw portion 51. The compression member 53 is screwed to the pressure member support block 29, the compression vane 53 is interposed between the bolt head 51b and the swing arm 46, and the swing arm 46 is biased counterclockwise about the fixed shaft 44 as a fulcrum. ing. That is, the upper calender roller 35 is pressed against the lower calender roller 34, pressurizing the sliver between the rollers 34, 35, and the oscillating arm 46 oscillates depending on the size of the sliver thickness (uneven sliver unevenness) to be applied. It is designed to move.

Further, as shown in FIGS. 1 and 4, the draft roller support block 28 is provided with a distance detection sensor 55 for measuring a distance between the draft roller support block 28 and a detected body 54 fixed to the lower surface of the swing arm 46. ing. The distance detection sensor 55 is connected to a control device 56, and the control device 56 controls the lower draft roller 58 such that the draft thickness becomes constant depending on the measured value from the distance detection sensor 55 and the rotation speed of the doffer or the calendar roller. Is calculated, and a shift command is output to the servo motor SM so as to rotate the lower draft roller 58 at this rotation speed.

Next, as shown in FIGS. 1 and 4, a roller shaft 57 is rotatably supported between the support blocks 28 via bearings 60, and a lower draft roller 58 is provided at the center of the shaft 57. It is fixed. A pulley 62 is fixed to the left end of the shaft 57, a belt 64 is wound around the pulley 62 and a pulley 63 fixed to the draft variable drive shaft 25, and the lower draft roller 58 rotates at a variable speed. It is free. As shown in FIG. 5, front and rear support walls 65 are fixed to the upper surfaces of the left and right draft roller support blocks 28, and both ends of the roller shaft 61 are fitted between the support walls 65. There is. An upper draft roller 59 is rotatably supported at the center of the roller shaft 61 via a bearing 66, as shown in FIG.

Further, as shown in FIGS. 2, 4 and 5, the base of a swinging piece 68 having a U-shaped cross section is swingably supported on each of the fixed shafts 44. A pressure member 70 biased downward by a spring 69 is attached to the swing piece 68 at a position corresponding to the roller shaft 61 of the upper draft roller 59, and as shown in FIG. The front end of the piece 68 is engaged with the hook pin 71 by the tip of the hook hook 72 rotatably supported by the pressure member support block 29. Therefore, when the hooking pin 71 and the hooking hook 72 are engaged with each other, the pressing body 70 presses both ends of the roller shaft 61 so that the lower drafting roller 58 and the upper drafting roller 59 are in pressure contact with each other.

As shown in FIG. 1, the feed roller side surfaces of the calendar roller support block 27 and the support wall 43 are formed on a continuous inclined mounting surface 74, on which a web focusing device 76 is fixed. There is. The web converging device 76 is an integrated device of a gatherer 77, a sliver guide 78 and a drampet 79. The gatherer 77 has a shape that is long in the machine width direction so as to cover the delivery rollers 4 and 5, and has a web focusing hole 80 in the center thereof so that a wide web supplied from the delivery rollers 4 and 5 can be provided. It converges and becomes a sliver. The sliver guide 78 attached to the front face of the gatherer 77 has an opening 81 for discharging excess air contained in the sliver formed above, and a hollow conical trumpet 79 is fixed to the front face of the sliver guide 78. Although the gatherer 77 of the web converging device 76 is of a fixed type, it may be of a rotary eplone type including a pair of conveyors as is well known.

Next, the operation of the card machine 1 configured as described above will be described. During normal operation of the card machine 1, the support 13 is positioned at the proximity position A as shown in FIG. Then, the doffer 2, the stripping roller 3, the feeding rollers 4, 5 and the lower calendar roller 34 are rotated at a predetermined speed ratio by the motor M. Further, the lower draft roller 58 is rotationally driven at a predetermined draft ratio with respect to the calendar roller 34 by the action of the servo motor SM. The wide web stripped from the doffer 2 by the stripping roller 3 is fed between the delivery rollers 4 and 5 and then converged by the web converging device 76 to form a sliver, which is then calendered. It is drafted between the rollers 34 and 35 and the draft rollers 58 and 59, and finally accommodated in a can (not shown).

In the moving operation of the sliver, when the sliver passes through the upper and lower calendar rollers 34, 35, the uneven thickness of the sliver causes the upper calendar roller 35 to move with respect to the lower calendar roller 34, and the swing arm 46. Swings around the fixed shaft 44 as a fulcrum. At that time, the distance detection sensor 55 has detected the detected object 54 of the swing arm 46, and the measurement value of the distance detection sensor 55 is sent to the control device 56, and the control device 56 makes the sliver thickness larger than the measurement value. The rotation speed of the lower draft roller 58 that becomes constant is determined, and a shift command is output to the servo motor SM. Therefore, during normal operation, the lower draft roller 58 is gear-shifted so that the sliver thickness is constant.

Next, when the operation of the card machine 1 is stopped and the work such as web spouting and sliver observation is performed, the rocking cylinder 20 is operated to work with the support 13 together with the web focusing device 76, the calendar rollers 34, 35. Also, the draft rollers 58 and 59 are oscillated to move from the proximity position A (shown in FIG. 1) close to the feed unit 6 to the separated position (shown in FIG. 6) away from the feed unit 6, and the feed unit 6 and the web concentrator. A sufficient working space is formed with 76, and the worker works. As described above, when the support 13 is swung from the approaching position A to the separating position B, the calendar rollers 34 and 35 and the draft rollers 58 and 59 are rotated clockwise in FIGS. Therefore, even if the work is performed while the sliver is being spliced, the sliver will not be fed in the opposite direction to the feeding direction. When the support 13 swings from the separated position B to the close position A, the calender rollers 34 and 35 and the draft rollers 58 and 59 rotate counterclockwise to prevent the sliver from breaking.

As described above, in the card machine 1 of the present embodiment, during normal operation, the draft rollers 58 and 59 are controlled to change speed according to the size of the thickness of the sliver. The slide thickness can always be set to a constant value, and a pair of upper and lower draft rollers 58 and 59 are provided downstream of the calendar rollers 34 and 35, and between the calendar rollers 34 and 35 and the draft rollers 58 and 59. Since the draft ratio is variable, the apparatus can be configured more compactly than the one in which two pairs of upper and lower draft rollers are provided downstream of the calendar roller and the draft ratio is changed between the front and rear draft rollers. Further, the web converging device 76, the calendar rollers 34, 35 and the draft rollers 58, 59 are integrally provided on the support body 13, and the support body 13 can be moved between a position A close to the delivery section 6 and a separation position B. Therefore, no extra moving space is required between the calendar rollers 34 and 35 and the draft rollers 68 and 59, and the support 13 is positioned at the separating position B during the work, and the space between the feeding unit 6 and the web concentrator 76 is reduced. Sufficient working space can be formed, and the worker can easily perform the work.

In the above-described embodiment, the sliver unevenness is detected by the upper and lower calendar rollers 34 and 35 provided with the groove 36 and the concave portion 37, and the distance detection sensor 55. A micrometer may be provided to detect the thickness of the sliver.

[Effect of device]

 As described above, in the card machine of the present application, the web focusing device, the calendar roller, and the draft roller are attached to the support body, and the support body is provided on the card machine base so as to be close to and away from the feeding portion. At the time of work, the support can be separated from the feed-out portion, and a sufficiently large work space can be formed between the feed-out portion and the web concentrator, so that the work can be performed easily. Moreover, since the draft roller and the support body also move closer to and away from the delivery section, no extra moving space is required between the draft roller and the calendar roller, and the fleece focusing portion including the draft roller can be made compact.
