Problems solved by technology

However, due to the rotation of the rollers during operation, the bolts can hardly be removed for changing the rollers or can no longer be removed at all
The so-called breakaway torques for removal have increased over time in such a way that the removal of the contact disks is rather difficult and the bearings of the corresponding contact disks are partially damaged so that the bearings have to be replaced

Embodiment Construction

[0024] figure 1 An arrangement 1 with creel 2 and a downstream draw frame 100 is shown in a conventional arrangement.

[0025] The creel 2 is constructed in a known manner and will not be described again.

[0026] Furthermore, the draw frame 100 has a coiling device 110 on the output side. The coiling device 110 comprises, in the example shown, a can track 111 for full cans and a preferably driven can guide 112 which moves the empty cans to the actual, unmarked coils on the can changer of the sliver plant 110 . The can changer has, for example, a can mover 113 in a known manner. On the side of the draw frame 100 there is an operating platform 102 . At one end of the operating platform 102 there is an operating terminal 101 here. Furthermore, a drafting mechanism cover 103 can be seen, which covers the drafting section 104 in a known manner. Upstream of the drafting section 104 in the fiber strand transport direction, there is a measuring system 120 , which has two unmark...

Abstract

The device (120) has a clamping section (124) and a roller section (126, 131, 127) with a drive section (131), a receiving section (126b) and a fastening section (123). The roller section (126) is rotationally connected to a drive element. The receiving section ( 126 b ) accommodates the roller ( 125 ) and is arranged downstream of the drive section ( 131 ), viewed along the axis of rotation of the roller section ( 126 ). The fastening section (123) is arranged downstream of the receiving section (126b) viewed in the direction and has a fastening opening (123a) which is open towards the clamping side facing away from the receiving section (126b). The solid opening extends towards the receiving section (126b) and is arranged outside the axis of rotation. The clamping section (124) rests on the receiving section (126b) from the clamping side and has an associated through-opening (122a) for each fastening opening (123a) which, viewed in the direction, corresponds to the Align with the fastening opening (123a). The fastening element (3) is force-fitted and / or form-fitted into the associated through-opening (122a) from the mounting side to hold the clamping section (124) on the roller (125). in the fastening opening (123a). The axes of rotation of the roller sections ( 126 ) of the two devices ( 120 ) of the measuring system ( 120 ) of the textile machine ( 100 ) run parallel to one another and are spaced apart from one another as viewed in this direction.

Description

technical field [0001] The present invention relates to the fastening of the rollers, in particular the measuring rollers of the drafting mechanism. Background technique [0002] Such rollers are constructed to be independent at one end. The rollers are thus fixed so as to be freely rotatable with respect to their axis of rotation, usually a clamping sleeve is put on from the free ends and fixed by means of centrally arranged screws. However, the rotation of the rollers during operation results in that the bolts can hardly be removed for replacing the rollers or can no longer be removed at all. The so-called breakaway torque for dismantling has increased over time in such a way that dismantling of the contact disks is rather difficult and partially damages the bearings of the respective contact disks, so that the bearings must be replaced. SUMMARY OF THE INVENTION [0003] The task of the present invention is to address said disadvantages. [0004] According to the inve...
