Problems solved by technology

The above two automatic doffing systems and the roving frame are not completely independent settings, and are not suitable for the upgrade of the roving frame
In addition, the above-mentioned automatic doffing system also has defects such as long doffing time and production efficiency that needs to be further improved.

Embodiment Construction

[0016] See Figure 1 and figure 2 , an automatic doffing system, including a yarn taking vehicle cover 1, a lifting platform cover 2, and a manipulator cover 3 for converting empty bobbins and full bobbins. When doffing, the take-up car in the take-up car set carries the doffing fork that is consistent with the number of spindles of the roving frame and moves forward to the designated position of the full bobbin, and the doffing fork removes the corresponding full bobbins respectively. Then the yarn-taking car moves to the designated position and waits to receive the following empty bobbins; the platform of the lifting platform lowers and delivers the empty bobbins with the same quantity as the number of spindles of the roving frame to the yarn-taking car. The doffing fork uses its front fork to pick up the corresponding empty bobbins, and the empty bobbins are transferred to the take-up car, and the take-up car moves forward to send the empty bobbin to the designated position ...

Abstract

The invention discloses an automatic doffing system, which comprises a charka, a lifting platform, empty bobbins and a full-bobbin conversion manipulator. The charka carried the doffing forks consistent with the number of spindles of a coarse spinner moves forward to take off the respectively corresponded full bobbins, and then the charka moves backward to a designated location to wait. The platform is dropped so that the empty bobbins can be delivered to the charka. The charka moves forward, moving back to the full yarn extraction position after sending the empty bobbins to the designated location. The platform extracted and carried the full bobbins is lifted to a designated height, waiting for the replacement. The manipulator is provided with two taking parts. When in the process that a taking part is taking a full bobbin of one position of the platform, the other taking part is taking an empty bobbin at the same time. Afterwards, two positions of the taking part are swapped and in handover. Respectively, the empty bobbin is handed over to a vacated position of the full bobbin, and the full bobbin is handed over to the next spinning procedure. Such-and-such until the full bobbins on the platform are all replaced to the empty bobbins. The invention and the coarse spinner are independently arranged to facilitate the upgrading and maintenance of the spinning users.

Description

technical field [0001] The invention relates to an automatic doffing system (device) for a roving frame. Background technique [0002] In the prior art, the automatic doffing system (device) of the roving frame is roughly divided into two categories from the installation layout: the built-in automatic doffing system and the external automatic doffing system. The main technical scheme adopted by the built-in automatic doffing system is roughly: the track is fixed on the upper dragon rib (lower dragon rib), the spindle nozzle and the empty bobbin tube are driven into the car by the drag chain, and the full yarn and the empty bobbin are carried out. Tube conversion. The main technical scheme adopted by the external automatic doffing system is roughly: the lifting platform is in front of the car (behind the car), when doffing, the lower dragon tendon moves forward (backward), and the lifting platform brings the hanging spindle and the empty bobbin down. Set (transfer) the full...
