Embodiment Construction

[0013] Referring to the drawings, these show, inter alia: a bobbin 1; a bobbin support arm, generally called a bobbin holder arm 2; a driving and transverse cylinder 3 (the cylinder 3 is connected to the Cooperate to form bobbins, and its existence and function have nothing to do with the specific purpose of the present invention); Conveyor belt 4 and rolling chute 5, are used for allowing bobbin 1 to be positioned at bobbin holder arm 2 by gravity from forming Location Scroll to Conveyor 4.

[0014] exist figure 1 In the working state of , the yarn (not shown) is unwound from the supply bobbin (not shown) and wound around the bobbin 1 after passing through a series of devices whose function is to eliminate yarn defects.

[0015] Corresponding to the detection of the pre-determined dimensions of the bobbins 1 formed, or, in any case, to the instruction to replace 1, as figure 2 It is shown that the yarn from the supply bobbin is cut off and the rotation of the bobbin 1 is ...

Abstract

The invention relates to a device for the automatic doffing of bobbins in a crosswinding machine, of the type comprising a rolling chute (5) on which the bobbin is free to roll towards a conveyor belt (4), wherein said rolling chute (5) is hinged around a rotation pin (8), around which it can rotate varying the level difference between its ends, a flap (9) being hinged to the end of said rolling chute (5) facing the conveyor belt (4), whose portion facing the conveyor belt (4) slides on a fixed supporting counter-edge (11).

Description

technical field [0001] The invention relates to a device for automatically doffing bobbins on cross-winding winders and for replacing bobbins that have reached a predetermined size with new bobbins on which yarn from a supply bobbin is wound on a new bobbin to form a new bobbin. Background technique [0002] It is known that the cross-winding operation mainly includes the unwinding of the yarn from the supply weft bobbin, the elimination of possible yarn defects of the yarn, and the operation of cross-winding on the bobbin according to the shape and size. The end goal of the line will vary. If the yarn is intended to be fed in a high-speed machine, the bobbin is usually cylindrical, or truncated with a slight taper, and conversely, if the yarn is intended to be fed in a low-speed machine, the bobbin It is a truncated cone with a larger taper. The taper is selected in such a way that it is always ensured that the bobbins are unwound correctly in the presence of more or les...
