Description

Field of the Invention

[0001] The disclosure relates to the field of dyeing and finishing equipment, and in particular to a yarn cage conveyor equipment.

Background of the Invention

[0002] In recent years, with the rapid development of textile dyeing and finishing industry, how to improve production rate and reduce cost becomes the primary task of each enterprise; and it is an inevitable tendency for dyeing to develop towards semi-automatization and full-automatization. The conveyance of yarn cage is an important factor for production rate and cost; therefore, fast and accurate conveyance of yarn cage has an important real significance in the dyeing industry.

[0003] In prior art, during the dyeing production of bobbin yarn, workers hoist a yarn cage in and out a dye vat through a manual crown block (that is, electric overhead travelling crane, also called motor hoist). The crown block in the prior art comprises a first beam, a second beam and a hanger, wherein the first beam moves along a first direction, the second beam is arranged on the first beam and can move along the extension direction of the first beam, and the hanger is arranged on the second beam through a steel cable. The first beam and the second beam are driven by a motor respectively, and the steel cable is dragged by a motor. During operation, an open-loop control mode is adopted, and the movements of the first beam, the second beam and the hanger are controlled by manually pressing a button on the operation handle of the crown block; when the hanger reaches a correct position, workers hang the lug of the yarn cage and the yarn cage on the hanger of the crown block using a steel cable, thereby implementing the conveyance of the yarn cage.

[0004] However, the yarn cage conveying method in the prior art has drawbacks as follows:

(1) Since the crown blocks is open-loop controlled and the manual operation is instable and immeasurable, the crown block can not be positioned accurately and the operation is time consuming.

(2) Since the steel cable is a flexible part, if the yarn cage and the crown block are viewed as a whole body, the rigidity is insufficient, consequently the steel cable has big swing and can not be controlled during the travelling process of the crown block hanging the yarn cage, thus collision and other safety accidents are easy to happen.

(3) Since workers need to connect the lug of the yarn cage with the hanger of the crown block using a steel cable every time, the operation is time consuming; further, the steel cable is easy to break due to abrasion and thus leads to accidents.

[0005] EP0316151A1 discloses an extendable multiple beam attached to a crab of an overhead traveling crane, wherein the multiple beams are provided with roller supporting members inside at their corners. Each roller supporting member is provided with one or more rollers which are in touch with a corner of another separate beam situated directly inside. When the inside beam moves upwards or downwards to let the multiple beam extend or retract, the rollers roll on the corner of the inside beam to lead the movement. The roller supporting members can be detached easily from the separate beams to inspect or exchange the rollers or other parts. CN102351102A discloses a winding machine yarn carrier.

Detailed Description of the Embodiments

[0018] The embodiment of the disclosure is described below in detail in conjunction with accompanying drawings. However, the disclosure can be implemented by multiple different methods limited and covered by the claims.

[0019] As shown in Fig. 1 and Fig. 2, the yarn cage conveyor equipment of the disclosure comprises: a first beam 100, a second beam 200, a mechanical gripper 300, a position detection unit and a control device, wherein the first beam 100 is arranged on a guide rail 400 and can move along the guide rail 400; the second beam 200 is moveably arranged on the first beam 100 and can move along the first beam 100; the mechanical gripper 300 is arranged on the second beam 200 and comprises a telescoping mechanism 310 and a grab mechanism 320 connected with the telescoping mechanism 310; the position detection unit is used for detecting the positions of the first beam 100 and the second beam 200; and the control device is used for controlling the movements of the first beam 100, the second beam 200 and the mechanical gripper 300 according to the position information detected by the position detection unit. Preferably, the position detection unit is a magnescale.

[0020] As shown in Fig. 3, a yarn cage 600 comprises a base 620 and a vertical post 610 arranged on the base 620, wherein the end part of the upper end of the vertical post 610 is provided with a grab part 611 matched with the grab mechanism 320. Preferably, the grab part 611 is a groove or a convex.

[0021] During use, the position detection unit detects the position of the first beam 100 and the second beam 200 at all times; the control device compares the information detected by the position detection unit with a preset position information of yarn cage; when the mechanical gripper 300 which has been conveyed through the composite motion of the first beam 100 and the second beam 200 is positioned above the yarn cage 600, the control device controls the telescoping mechanism 310 to extend downwards (that is, towards the yarn cage 600); when the grab mechanism reaches the preset position, the control device further controls the grab mechanism to capture the grab part 611 of the yarn cage 600. Then, the control device can control the telescoping mechanism 310 to contract so as to lift the yarn cage 600, and further control the first beam 100 and the second beam 200 to move to a target position. Thus it can be seen that, in the whole operation, the yarn cage conveyor equipment of the disclosure realizes close-loop control through the position detection unit and the control device, thereby realizing the accurate positioning of the mechanism gripper 300, improving working efficiency, shortening production cycle and reducing labour cost. Meanwhile, the disclosure uses the grab mechanism 320 to capture the yarn cage 600, thereby overcoming the disadvantage existing in prior art that workers need to connect the yarn cage 600 with the crown block through a steel cable, improving rigidity and stability of operation. During the entire conveying process, the yarn cage 600 would not swing greatly, thereby avoiding collision and other potential safety accidents, and avoiding accidents caused by worn and broke steel cable.

Particularly, the piston rod of the first cylinder 312 is connected with the connecting plate 314 through a connecting rod 315. Refer to Fig. 2, the upper end of the guide rod 311 can move freely in the vertical direction; when the telescoping mechanism 310 performs an extension motion, the upper end of the guide rod 311 moves downwards; when the telescoping mechanism 310 performs a contract motion, the upper end of the guide rod 311 moves upwards.

[0026] As shown in Fig. 2 and Fig. 3, the grab mechanism 320 comprises: a second cylinder 321, a jaw 323 and a base 322; the second cylinder 321 is mounted on the base 322; the jaw 323 comprises a first hinge part 324 and a second hinge part; the jaw 323 is connected with the base 322 through the first hinge part 324, and the jaw 323 is connected with the piston rod of the second cylinder 321 through the second hinge part. Through the second cylinder 321, the jaw 323 can be expanded and closed. When the jaw 323 is closed, the yarn cage 600 can be grabbed; when the jaw 323 is expanded, the yarn cage 600 can be released. Preferably, the jaw 323 has a self-locking function to prevent accidentally loose.

[0027] As shown in Fig. 2 and Fig. 4, the yarn cage conveyor equipment further comprises a guide device 500, which comprises a frame 510 and a guide wheel mounted on the frame 510, wherein the guide wheel contacts the guide rail 400 in a rolling manner.

Preferably, there are two guide wheels. At least one part of the guide rail 400 is clamped between the two guide wheels. When two guide wheels are adopted, the guide rail 400 can be clamped between the two guide wheels, thus guide effect is improved, error is reduced and the precision of positioning and re-positioning is improved. Preferably, the frame 510 is provided with a mounting hole 550; the inside of the frame 510 is provided with a reinforced rib 520. The guide device 500 can be mounted on the first beam 100 through the mounting hole 550 and a bolt.
