Description

Translation device of integral doffing pipe gripper

Technical Field

The utility model belongs to the technical field of the spinning frame and specifically relates to a ware translation device is grabbed in collective doffing.

Background

When the spinning frame pipe gripper works, two strokes, transverse translation and vertical movement need to be realized, the vertical movement is realized by a herringbone swing arm in the prior art, the transverse translation is realized as disclosed by a translation type pipe gripper combination device disclosed by the utility model patent with the patent number of 201620263867.0, a plurality of transverse horizontal guide rails need to be arranged on a rack, a pipe gripper cross beam is driven from the inner side to the outer side of the rack under a linear driving mechanism, and the length of the horizontal guide rails is not less than the stroke required by the pipe gripper cross beam, so that the horizontal guide rails form a plurality of convex parts in the transverse direction of the spinning frame, and form obstacles for operators and articles; in addition, in order to provide a horizontal guide rail with a certain stable structure, a lifting beam is required to be arranged on the herringbone swinging arm to serve as a connection foundation of the horizontal guide rail and a corresponding linear driving mechanism, and the load of the herringbone swinging arm is large no matter whether the linear driving mechanism is an air cylinder or a gear rack mechanism.

Disclosure of Invention

The utility model aims to solve the above problem, provide a pipe ware translation device is grabbed in collective doffing that the stroke of grabbing tub ware crossbeam does not rely on horizontal guide rail to reduce horizontal migration mechanism to the occupation in horizontal space on the one hand, on the other hand reduces the load of chevron shape swing arm, specifically realizes by following technical scheme:

a translational device for collective doffing tube grippers comprises a tube gripper cross beam provided with a plurality of tube grippers and at least two long herringbone arms, wherein the two long herringbone arms are arranged on a rack in an up-and-down swinging manner, the upper ends of the long herringbone arms are respectively provided with a rotating shaft and a driving mechanism for driving the rotating shaft to rotate, the rotating shafts are respectively and fixedly connected with horizontally arranged swing rods, and one ends of the swing rods are hinged with the tube gripper cross beam through pin shafts; when the rotating shaft rotates, the pipe gripper beam can horizontally move transversely.

The device for translating the doffing tube grippers collectively is further designed in such a way that the driving mechanism comprises a motor and a pair of bevel gears, and the motor drives the rotating shaft to rotate through the bevel gears.

The integral doffing pipe gripper translation device is further designed in that a rotating shaft base is hinged to the upper end of the long herringbone arm, the rotating shaft is rotatably arranged on the rotating shaft base, a motor base is fixedly arranged on one side of the rotating shaft base, the motor is arranged on the motor base, and a pair of bevel gears which are meshed with each other are fixedly arranged on the rotating shaft and an output shaft of the motor respectively.

The beneficial effects of the utility model reside in that:

the swing rods are driven to rotate through the rotating shaft, so that the pipe gripper cross beam, the rack and the at least two swing rods form a parallel four-bar linkage mechanism, and the pipe gripper cross beam can obtain a stroke which is twice as long as the swing rods, namely the stroke of the pipe gripper cross beam is not equal to the length of the horizontal guide rail, so that the problem of interference caused by the horizontal guide rail in the prior art is basically eliminated; in addition, because a horizontal guide rail is not required to be arranged, a lifting cross beam serving as a horizontal guide rail connection foundation is omitted, and the load of a vertical driving mechanism, namely the herringbone swinging arm, is directly lightened.

Detailed Description

The invention is further described with reference to the drawings and examples in the following description:

the integral doffing pipe gripper translation device comprises a pipe gripper cross beam 1 provided with a plurality of pipe grippers and at least two long herringbone arms 2, wherein the lower ends of the long herringbone arms are hinged on a rack, the middle parts of the long herringbone arms are hinged with one ends of short herringbone arms 3, the other ends of the short herringbone arms 3 are horizontally and linearly movably arranged on the rack through a screw rod mechanism 4 shown in the figure, and therefore the two long herringbone arms can be vertically and swingably arranged on the rack; the upper end of the long herringbone arm 2 is respectively provided with a rotating shaft 5 and a driving mechanism 7 for driving the rotating shaft to rotate, the rotating shafts 5 are respectively and fixedly connected with swing rods 6 which are horizontally arranged, and one end of each swing rod is hinged with the pipe gripper cross beam 1 through a pin shaft; when the rotating shaft rotates, the pipe gripper beam 1 can horizontally move.

The swing rods are driven to rotate through the rotating shaft 5, so that the pipe gripper beam 1, the rack and the at least two swing rods 6 form a parallel four-bar linkage as shown in the figure, and the pipe gripper beam 1 can obtain a stroke twice as long as the swing rods, namely the stroke of the pipe gripper beam 1 is not equal to the length of the horizontal guide rail, so that the problem of interference caused by the horizontal guide rail in the prior art is basically eliminated.

Specifically, the drive mechanism 7 includes a motor 71 and a pair of bevel gears 72, and the motor rotationally drives the rotary shaft via the bevel gears. The upper end of the long herringbone arm is hinged with a rotating shaft base, the rotating shaft is rotatably arranged on the rotating shaft base 73, a motor base 74 is fixedly arranged on one side of the rotating shaft base, the motor is arranged on the motor base, and a pair of bevel gears which are meshed with each other are fixedly arranged on the rotating shaft and an output shaft of the motor respectively.

Obviously, compared with the prior art, because the horizontal guide rail is not required to be arranged, the lifting beam serving as the connection foundation of the horizontal guide rail is eliminated, and the load of the vertical driving mechanism, namely the herringbone swinging arm, is directly lightened.
