Description

[Detailed description of the invention] [Industrial application field] A clearer device installed above the detaching roller of a combing machine used in the spinning process. The endless apron is configured to swing along the touching roller and in relation to the swinging of the detaching roller, and to rotate the endless apron in relation to this swinging.

[Prior Art] It is well known that a clearer device is attached to the top of the top detaching roller of a conventional combing machine. Generally, plate-shaped or roll-shaped clearers are used as these clearer devices, but these clearers can jump up due to the reciprocating movement and rotation of the detaching roller, and the contact surfaces are separated and cannot be reliably It is suitable for the disadvantage that cleaning cannot be carried out. Further, with such a clearer, it is necessary to remove peelable fibers attached to the clearer. Based on the above, the present applicant has provided an apron-type clearer with an endless apron above the top detatting roller, and also makes the clearer oscillate in response to the movement of the back top detatting roller. We are proposing a system that rotates the endless apron. For example, Jikko 52-
Publication No. 27940 is that. However, in the clearer device disclosed in this publication, the specific structure and operating means thereof were insufficient, and there were problems in handling and maintenance.

[Problems to be Solved by the Invention] Therefore, the present invention improves the structure of such an apron-type clearer device by driving the rotation of the endless apron by swinging the clearer. It is designed to be easy to handle and to ensure reliable operation management.

[Means for Solving the Problems] That is, the present invention connects the clearer roller shaft via two swinging suspension rods to a suspension shaft that supports both ends of the stud provided on the roller stand via a bracket. A clearer frame consisting of a side wall, a frame fixed to this side wall, and a cross guide attached to this is pivotally supported on both sides of the clearer roller with the clearer roller being sandwiched between the clearer roller shaft. One end of the clearer roller shaft is supported and swung in a groove of a swing arm pivotally supported by the stud, and a ratchet gear is attached to the other end, and this ratchet gear is fixed to the clearer roller shaft and The ratch gear is rotated by the swinging of the clearer roller shaft in correspondence with the engagement pawl provided in the case which is biased by a coil spring, and the clearer roller shaft is rotated, and the clearer roller shaft is attached to the hanging support shaft. The comb bar to which the comb is attached is pivotally supported via a comb lever, and the comb is brought into contact by its own weight with an apron clearer roller that is stretched between a clearer roller and a cross guide, and the comb bar is attached to the protruding boss portion at the other end of the swing arm. One end of the oscillating lever is pivotally supported.
