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.

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

with the connecting plate 314 respectively; the grab mechanism 320 is connected with
the connecting plate 314. 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;
