Description

Technical Field

[0001] The invention belongs to the technical field of yarn processing, and in particular relates to a device for identifying the direction of yarn rod ends. Background Art

[0002] In the industrial production process, yarn production generally includes the following steps: (1) the spinning stage: a strand is ring-spun to produce bobbin yarn; (2) the winding process: the yarn is unwound from the bobbin (yarn rod), its defects are cleaned and it is rewound into a package, which contains a larger number of yarns.

[0003] When the yarn enters the winding process and is unwound from the yarn rod, the yarn rod will exist in four states. The first is that the yarn on the yarn rod is not successfully unwound, that is, the bobbin yarn is still complete; the second is that a small part of the yarn on the yarn rod is unwound, that is, most of the yarn remains; the third is that most of the yarn on the yarn rod is unwound, that is, a small part of the yarn remains; the fourth is that the yarn on the yarn rod is completely unwound, that is, the yarn rod without yarn.

[0004] After the unwinding process is completed, the yarn rods need to be recycled and reused. The diameters of the two ends of the yarn rods are different, that is, the two ends are respectively a large end and a small end. For ease of use, the recycled yarn rods need to be placed in a consistent manner during recycling. However, in the existing process, most of the arrangements are made by manually adjusting the direction of the yarn rods. This method is inefficient and brings a lot of workload to production and processing. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a device for identifying the direction of the big and small ends of a yarn stick, which can identify the big end and the small end of the yarn stick to facilitate the arrangement of the yarn sticks.

[0006] The technical solution of the present invention is: a device for identifying the direction of yarn rod ends, comprising:

[0007] A conveying mechanism for conveying the yarn sticks;

[0008] Two identification components, the identification components include a test arm that can be displaced along the conveying direction, an inner guide piece arranged along the conveying direction, an outer guide piece arranged opposite to the inner guide piece, and a displacement sensor for sensing displacement information of the test arm, and the area between the inner guide piece and the outer guide piece forms an identification channel through which the end of the yarn supply rod passes;

[0009] A guide member, disposed on the support plate and used to guide the movement of the yarn stick so that the end of the yarn stick enters the identification channel;

[0010] The outer guide plate is provided with a strip limiting groove arranged along the conveying direction, one end of the test arm passes through the strip limiting groove and extends into the identification channel, and when the yarn rod passes through the identification channel, the end of the yarn rod can push the corresponding test arm to move in the strip limiting groove.

[0011] The principle of the head identification mechanism in the present invention is:

[0012] When the yarn stick transported on the conveying mechanism is transported to the large and small head identification mechanism station, it is guided by the guide member during the transportation process so that the yarn stick passes through the identification channel. The two ends of the yarn stick correspond to the two identification channels respectively. As the yarn stick moves, since the diameter of the big end of the yarn stick is larger, the big end of the yarn stick will preferentially contact the test arm corresponding to the position of the big end, pushing the test arm to move. When the test arm undergoes displacement changes, the corresponding displacement sensor will sense the displacement change of the test arm, and the position and direction of the big end and the small end of the yarn stick can be determined.

[0013] The guide member in the present invention may have various structural forms. Preferably, the guide member is a spring guide piece.

[0014] Preferably, the large and small head identification mechanism further comprises a mounting plate for mounting a test arm, the test arm comprises a connecting portion connected to the mounting plate and movable relative to the mounting plate, and a reset spring is arranged between the connecting portion and the mounting plate. After the yarn rod passes through the test channel, in order to facilitate the test of the next yarn rod, the test arm can be restored to its original position under the action of the reset spring, so as to wait for the identification of the large and small ends of the next yarn rod.

[0015] Preferably, the displacement sensor is mounted on the mounting plate.

[0016] Preferably, the mounting plate is provided with a position adjustment slot for mounting and adjusting the position of the displacement sensor. The present invention can adjust the position of the displacement sensor in the position adjustment slot according to actual needs.

[0029] The guide member 42 is disposed on the support plate 11 and is used to guide the movement of the yarn stick so that the end of the yarn stick enters the identification channel. The guide member 42 in the present invention can have various structural forms, and the guide member 42 is a spring guide piece.

[0030] The outer guide plate 413 is provided with a strip-shaped limiting groove arranged along the conveying direction. One end of the test arm 411 passes through the strip-shaped limiting groove and extends into the identification channel. When the yarn stick passes through the identification channel, the end of the yarn stick can push the corresponding test arm 411 to move in the strip-shaped limiting groove.

[0031] The principle of the present invention is:

[0032] When the yarn stick transported on the conveying mechanism 1 is transported to the station of the large and small end identification mechanism 4, it is guided by the guide member 42 during the transportation process so that the yarn stick passes through the identification channel. The two ends of the yarn stick correspond to the two identification channels respectively. As the yarn stick moves, since the diameter of the big end of the yarn stick is larger, the big end of the yarn stick will preferentially contact the test arm 411 corresponding to the position of the big end, pushing the test arm 411 to move. When the test arm 411 undergoes a displacement change, the corresponding displacement sensor 414 will sense the displacement change of the test arm 411, and the position and direction of the big end and the small end of the yarn stick can be determined.
