BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card machine in which a card cylinder is rotatably provided between left and right cylinder bends, and a flat group is rotatably provided so as to cover an upper peripheral surface of the card cylinder. is there.

[0002]

2. Description of the Related Art In a conventional general card machine, a fixing member (flexible bend) is attached to an outer upper part of a cylinder bend, and both ends of a flat located on an outer periphery of an upper part of a card cylinder are attached by arcuate supporting surfaces of the fixing member. Since it is supported, friction occurs between the flat and the supporting surface of the fixing member on which the flat slides, and the flat or fixing member wears, and the gauge between the flat cloth and the wire of the card cylinder is There was a problem that it was not kept constant for a long period of time and had to be adjusted frequently.

To solve this problem, JP-A-60-19
There is a card machine disclosed in Japanese Patent No. 4123, which is
A large number of arcuate rollers are rotatably mounted on the outer upper part of the cylinder bend, and the guide support surface of the flat end is formed at the upper ends of these many rollers, or an endless belt is provided between the rollers arranged in such a manner. There has been one in which both ends of the flat are supported by winding and the upper surface of the belt and the roller rotates or the conveyor belt circulates as the flat moves around, thereby preventing the generation of friction between the roller or the conveyor belt and the flat.

[0004]

In the conventional card machine described above, since a flat arc-shaped guide supporting surface is formed by a roller positioned on the outer circumference of the upper part of the card cylinder or a belt hung on the roller, a considerable number of them are formed. Without the use of rollers, a guide support surface that can smoothly guide the flat cannot be obtained, and the structure is complicated as a whole, and maintenance is not easy. In addition, since the distance between these adjacent rollers is very small, this part is easily clogged with fly dust that floats in the factory, and there are many rotating parts. It was high, and the rotation of the roller and the conveyor was not performed smoothly, and the flat could not move smoothly in some cases.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A card machine 1 of the present invention will be described with reference to the drawings. A card cylinder 4 is rotatably provided by a driving device (not shown) between the left and right cylinder bends 3 fixed to the side frame 2. A wire 7 is provided on the peripheral surface of the card cylinder 4 together with a clothing 6 attached to a flat 5a, which will be described later, for performing a carding action on the fibers. An endless flat group 5 is wound around three plane blocks 8 in the drawing, which are rotatably supported by a support member (not shown) provided on the cylinder bend 3. The flat group 5 is formed by connecting a plurality of flats 5a by a chain 9, and one of the plane blocks 8 is rotatable by a driving device (not shown). It is possible to go around by covering the upper peripheral surface of the. Further, at both ends of the flat 5a, a gauge block 10 supported by a supporting surface 15 of a rotating ring 14 described later is provided.
Is installed. Therefore, by changing the gauge block 10 to a different size, the spacing S between the mounting surface of the flat 54a to which the clothing 6 is mounted and the mounting surface of the card cylinder 4 to which the wire 7 is mounted (shown in FIG. 4). ) Can be changed to an arbitrary size, and the gauge T can be kept constant no matter which size of the clothing (wire) of different lengths produced by many manufacturers in the spinning factory is selected and used. The intervals can be set.

Next, the rotating ring 14 rotatably supported on the outside of the cylinder bend 3 will be described. The outer peripheral surface of the rotating ring 14 serves as a supporting surface 15 for supporting the gauge block 10 of the flat 5a positioned on the upper peripheral surface of the card cylinder 3 over the entire circumference, and the inner peripheral surface has, for example, five rotations in the illustrated case. It is supported by rollers 13. The rotary roller 13 is rotatably supported by the tip of the slide member, and the slide member 11 is mounted on a guide member 12 fixed to the cylinder bend 3 and the side frame 2 so as to be movable in the radial direction. Further, one end of an adjusting screw 16 is screwed to the slide member 11, and the other end of the adjusting screw 16 is positioned by a tightening nut 18 and an adjusting nut 19 via a through hole 17 of the guide member 12. Then, the tightening nut 18 is loosened and the adjusting nut 19 is adjusted to move the adjusting screw 16, so that the rotary roller 13 together with the slide member 11 can be adjusted in the mounting position in the radial direction. Therefore, the rotating ring 14 can be eccentrically moved by adjusting the mounting positions of the five rotating rollers 13 in the radial direction, and the distance (gauge) T (gauge) between the clothing 5 of the flat 5a and the wire 7 of the card cylinder 4 can be adjusted. (Shown in FIG. 4) can be finely adjusted. Further, a power transmission belt 22 is stretched around a pulley 20 attached to one of the rotary rollers 13 and a pulley 21 attached to one of the plain blocks 8, and the plain block is moved along with the orbital movement of the flat 5. The rotation of 8 is transmitted to the rotating roller 13 and the rotating ring 1
4, the support surface 15 of the flat member 4 positively rotates at the same speed as the orbital speed of the flat 5. It should be noted that, of the five rotary rollers 13, two rotary rollers 13 attached to the side frame 2 in FIG. 1 are biased radially outward by springs so that the loads applied to the five rotary rollers 13 become equal. Is desirable.

Next, the card machine 1 configured as described above
The action of will be described. When the card machine 1 is operated, the take-in roller 24 and the doffer 25 rotate counterclockwise, and the card cylinder 4 rotates clockwise. Further, the flat group 5 orbits counterclockwise, and at this time, the rotary roller 13 is rotated by the power transmission belt 22, and the rotary ring 14 rotates clockwise at the same speed as the orbital speed of the flat group 5. The wrap supplied by the action of a dish plate and a feed roller (not shown) is passed by the take-in roller 24 to the card cylinder 4 in sequence while performing the dust removal and fiber opening actions, and the carding action between the flat group 5 and the cylinder. By this, small fruit residue, leaf residue and short fibers are removed, separated into individual fibers, transferred to the doffer 25, formed again into fiber scraps, and taken out from the doffer 25 as a web by a doffing device (not shown).

As described above, in the card machine 1 of this embodiment, the rotary ring 1 is rotated at the same speed as the orbital speed of the flat group 5.
4 is rotated and the support surface 15 of the rotating ring 14 supports the gauge blocks 10 provided at both ends of the flat 5, so that no friction occurs between the gauge block 10 and the rotating ring 14 and the gauge block 10 (Rotating ring 14)
Can be prevented from being worn, and the gauge T can be kept constant for a long period of time. Further, since the flat 5a located on the upper peripheral surface of the card cylinder 4 is supported by the supporting surface 15 of one rotating ring 14 instead of a large number of rollers as in the conventional case, the structure of the device itself is simplified, In addition, since there are few rotating parts, it is possible to minimize the occurrence of defects due to the attachment of cotton wool.

In the card machine 1 of this embodiment, since the distance S between the mounting surface of the flat 5a to which the clothing 6 is mounted and the peripheral surface of the card cylinder 4 to which the wire 7 is mounted can be changed, it is flat. Although the gauge blocks 10 are attached to both ends of 5a, the gauge blocks 10 may be removed and the rotary ring may be changed as shown in FIGS. The rotary ring 50 is composed of an inner ring 51 and a plurality of arc members 52, and the arc members 52 are fixed to the side surfaces of the inner ring 51 by screws 55 via the long grooves 54 in the radial direction. The outer circumference of the circular arc member 52, which is continuous with a slight circumferential gap, serves as the support surface 15 that supports both ends of the flat 5a.
Further, the arc member 52 has a protruding piece 52a on which the adjusting bolt 5 is attached.
3 is attached, and the tip of the adjusting bolt 53 is in contact with the peripheral surface of the cylindrical portion 51a of the inner ring 51. Therefore, the circular arc member 52 is provided with a screw 5 to the side surface of the inner ring 51.
It is possible to adjust the position in the radial direction by releasing the fixation by 5 and adjusting the adjusting bolt 54.
The distance S between a and the card cylinder 4 can be adjusted.
By adjusting the position of the arc member 52, the plurality of arc members 5
Although the support surface 15 formed by the outer peripheral surface of 2 is not exactly a perfect circle, the amount of radial movement of the arc member 52 with respect to the diameter of the inner ring 51 is extremely small, which poses no practical problem. There is no. Further, even if the gauge blocks 10 are attached to both ends of the flat 5a, the rotating ring may be changed to the above-described configuration, and the gauge blocks 10 may be supported by the supporting surface of the arc member 52 without any problem.

Further, in the above embodiment, the rotary ring 14
Is configured so that one of the rotary rollers 13 is connected to one of the plain blocks 8 by a power transmission belt 22 so as to positively rotate, but this is stopped, and hooking recesses are formed on the support surface 15 of the rotary ring 14 at a predetermined pitch. The engaging pieces that engage with the hooking recesses are provided in the gauge blocks 10 at both ends of the flat 5 corresponding to the pitch of the hooking recesses, and the engaging pieces of the gauge block 10 are moved by the orbital movement of the flats so that the hooking recesses of the rotary ring 14 are engaged. Alternatively, the rotating ring 14 may be positively rotated by hooking. Further, due to the friction between the gauge block 10 and the supporting surface 15 of the rotating ring 14, the rotating ring 14 may rotate at the same speed by the orbital movement of the flat 5a.
