Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0021] see figure 1 , figure 2 , an embodiment of an automatic doffing trolley in the present invention, including a grabbing device 1 with a yarn gripper 5 and a yarn cutter 4, and the gripping device 1 is arranged above the yarn gripper 5 and the yarn cutter 4 A clamping auxiliary device. The yarn clamping auxiliary device includes an L-shaped yarn guide plate 3 and a yarn guide hook 2. The inner side of the L-shaped yarn guide plate 3 is a V-shaped groove in the middle, and the V-shaped groove of the L-shaped yarn guide plate reaches the L-shaped yarn guide plate. The inner sides of the two ends of the shaped yarn guide plate are smooth curves. The yarn guide hook 2 includes a fixed part and a crotch part, the yarn guide hook 2 fixed part is V-shaped, the V-shaped fixed part of the yarn guide hook is fixed on the edge of the V-shaped groove of the yarn guide pl...

Abstract

The invention provides an automatic doffing car, which comprises a gripping device with a yarn gripper and a yarn cutter and is characterized in that: the gripper device is provided with a yarn gripping auxiliary device above the yarn gripper and yarn cutter; the yarn gripping auxiliary device comprises an L-shaped yarn guide plate and a yarn guide hook; a V-shaped groove is formed in the middle of the inner side of the L-shaped yarn guide plate; the yarn guide hook includes a fixed part and a hook part, wherein the fixed part of the yarn guide hook is fixed on the edge of the V-shaped groove of the yarn guide plate; the yarn guide hook part has an arch-shaped structure which is raised upwards; the yarn guide hook and the V-shaped groove form a notched triangular yarn guide area which is in the cutting range of the yarn cutter and gripping range of the yarn gripper; the yarn can be cut and clamped in the triangular yarn guide area; and when the tube yarn is gripped above the yarn guide plate of a yarn cleaner after the doffing car reaches to the pointed position, the auxiliary yarn is sent to the yarn cutting and clamping positions rapidly and accurately.

Description

technical field [0001] The invention relates to a kind of textile machinery equipment, in particular to a doffing trolley equipped with a fine-link automatic winding machine and a tray-type automatic winding machine, specifically an automatic doffing trolley. Background technique [0002] The automatic doffing trolley is a kind of doffing equipment equipped on the automatic winding machine, and it is a necessary configuration on the fine-link automatic winding machine and the tray-type automatic winding machine. It is an automatic doffing equipment selected according to user requirements on the basic type of automatic winding machine. Its purpose is to reduce the labor intensity of the car operator and realize the automation of doffing. [0003] When the single spindle sends a full bobbin signal, the doffing trolley will remove the full bobbin from the support arm, put the prepared empty bobbin on the support arm, and grab the bobbin from the designated position by the grab...
