Description

Technical Field

[0001] The present invention relates to an automated creel hanger device, belonging to the technical field of printing and dyeing automation. Background Art

[0002] In the yarn dyeing industry, the yarn bobbins with the yarn wound on them are usually stacked on a creel, which is then hoisted into the dye vat of the dyeing machine. A hydraulic pump is then used to circulate the dye liquid in the vat so that the fine pigment molecules in the dye liquid can penetrate into the fiber structure of the yarn. The creel has always been hoisted manually and with traditional hook-type lifting equipment.

[0003] With the development of science and technology and the country's active promotion of automation technology, dyeing and finishing machinery, as an important industrial industry, has been included in the key projects of industrial automation. In order to cooperate with the development of the intelligent dyeing plant project, the above-mentioned manual creel lifting operation is the first part to be solved. Replacing manual processing with electromechanical control can greatly improve production efficiency and economic benefits. In order to fully build the configuration of an unmanned dyeing plant, a set of lifting equipment that cooperates with the automated creel lifting system is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to provide a set of automated creel hoisting devices, which can comprehensively improve the operational efficiency and economic benefits of creel hoisting, and further meet the needs of automated creel transportation in unmanned dyeing plants.

[0005] Specifically, the automated creel hanger device described in the present application includes a center column, a claw arm, a claw arm opening and closing ring, a driving device and a locking claw device. The claw arm is opened and closed on the outer surface of the center column. The claw arm opening and closing ring moves up and down along the outer wall of the center column under the drive of the driving device to push the claw arm to open and close. The locking claw device is arranged on the periphery of the claw arm opening and closing ring.

[0006] Furthermore, the center column is a cylinder, and its size, shape and material are designed and selected based on the safety stress level generated by the weight of the lifting load on the center column; a center column locking pin is provided on the top of the center column, and is connected to the center column top cover through the center column locking pin; the center column of the creel hanging claw is connected to the overhead crane system through the locking pin and the top cover. When necessary, the center column can be separated from the overhead crane by pulling out the locking pin.

[0007] Furthermore, there are several claw arms, and a protruding mounting block for installing the claw arm is provided at the bottom of the central column. The claw arm is installed on the mounting block of the central column through a claw arm locking pin. Its size, dimension, shape and material are designed and selected based on the safety stress level generated by the weight of the lifting load on the claw arm.

[0008] Furthermore, the number of the claw arms is three, and the three claw arms are distributed on the bottom periphery of the central column at equal intervals of 120°.

[0009] Furthermore, the claw arm locking pin forms a movable hinge, which enables the claw arm to have flexible opening and closing movements. The tip of the claw arm is designed with a curved hook shape so as to be used to pick up the oblate top of the central hanging column of the creel.

[0010] Furthermore, the upper end of the claw arm is designed with a curved track to cooperate with the rising action of the claw arm opening and closing ring to open the claw arm tip. When the claw arm opening and closing ring descends, the claw arm tip will return to a naturally closed state.

[0011] Furthermore, the driving device is a pneumatic pump, which is arranged on the central column, and its end is connected to the claw arm opening and closing ring, pushing the claw arm opening and closing ring to move up and down along the surface of the central column.

[0012] Furthermore, the claw arm opening and closing ring is composed of two fixedly connected circular rings, the upper ring is smaller and is sleeved on the periphery of the central column, while the lower ring is larger and is sleeved on the periphery of the mounting block.

[0013] Furthermore, the upper ring slides vertically up and down along the surface of the central column, while the lower ring slides down along the surface of the mounting block at the bottom of the central column.

[0014] Furthermore, the top periphery of the lower ring is provided with pulleys equal in number to the claw arms and corresponding in position. Furthermore, the number of the pulleys is three, and the three pulleys are arranged at equal intervals of 120°.

[0015] Furthermore, the surface of the pulley contacts the curved track of the claw arm. When the claw arm opening and closing ring moves upward, the pulley will push the curved track of the claw arm toward the surface of the center column through the lever action of the claw arm locking pin, so that the claw arm tip opens outward; when the claw arm opening and closing ring moves vertically downward, the pulley will also close the claw arm tip through the lever action of the locking pin hinge. When the claw arm opening and closing ring drops to the lowest position, the inner diameter of the lower ring will naturally limit the claw arm, so that the claw arm cannot be opened. It is used to limit the rise of the claw arm opening and closing ring to ensure that the claw arm will not be accidentally opened due to the accidental rise of the claw arm opening and closing ring.

[0016] Furthermore, the locking claw device is arranged on the periphery of the claw arm opening and closing ring, including a half-moon gear lock pin, a first half-moon lock pin, a second half-moon lock pin and a driving gear; the half-moon gear lock pin, the first half-moon lock pin and the second half-moon lock pin jointly form a circular ring, which surrounds the axis of the central column and is driven by an electric motor and a driving gear to rotate clockwise and counterclockwise and swing back and forth.

[0017] Furthermore, the half-moon gear lock pin, the first half-moon lock pin and the second half-moon lock pin are all provided with pin keys protruding inward, and the lower ring edge of the claw arm opening and closing ring is provided with a milling groove gap for the pin keys to be inserted.

[0018] Furthermore, the pin key can rotate and swing back and forth at the bottom of the center column, and the cylindrical surface at the bottom of the center column is provided with a vertical keyway corresponding to the pin key. When the pin key enters the keyway, the claw arm opening and closing ring can move upward. However, when the pin key is not in the keyway, the claw arm opening and closing ring is blocked by the bottom of the center column and cannot move upward, thus forming a pin arm effect.

[0019] Furthermore, the automated creel hanger device also includes a central hanging column, and a round disc for the claw arm to grab is provided on the top of the central hanging column.

[0020] Furthermore, the disc is provided with a ring so that the creel can be lifted by a conventional hook when necessary. The size, shape and material of the disc and the ring are designed and selected based on the safe stress level of the disc and the ring caused by the weight of the lifting load.

[0021] The automated creel hoist device described in the present application can comprehensively improve the operational efficiency and economic benefits of creel hoisting, and further meet the automated creel transportation needs of unmanned dyeing plants. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following non-limiting description of the technical solution described in the present application is given in conjunction with the accompanying drawings and embodiments.

[0035] The automatic creel hanger device described in the present invention comprises a creel hanger claw and a central hanger column, wherein the creel hanger claw is used to grab the central hanger column, such as Figure 1-2 As shown, the creel hanging claw comprises a center column 3, a claw arm 5, a claw arm opening and closing ring 4 and a locking claw device; a center column top cover 1 is provided at the top of the center column, and the center column top cover 1 is connected to the center column 3 using a center column top cover locking pin 6. The center column 3 can be separated from the center column top cover 1 by simply pulling out the center column top cover locking pin 6; three pneumatic pumps 2 are also provided on the center column 3 at equal intervals of 120° to push the claw arm opening and closing ring 4 up and down. The center column top cover 1, the center column 3 and the center column top cover locking pin 6 are all made of steel, and their size and shape are designed according to the safety stress level generated by the weight of the lifting load.

[0036] like Figure 3 As shown, the three claw arms 5 are equally spaced at 120° and are installed at the bottom of the center column 3 using a claw arm locking pin 7. The claw arm locking pin 7 forms a movable hinge, allowing the claw arms 5 to open and close flexibly.

[0037] The claw arm 5 is made of steel, and its size and shape are designed according to the safe stress level caused by the weight of the hoisted load.

[0038] like Figure 4As shown, the upper ring hole of the claw arm opening and closing ring 4 slides vertically up and down along the surface of the center column 3, while the lower ring hole slides along the surface of the bottom of the center column 3. Three pulleys 8 are installed around the top of the lower ring, and the three pulleys 8 are installed at equal intervals of 120°. The claw arm opening and closing ring 4 is made of steel, and its size and shape are mainly designed considering the shape and size of the center column 3 and the opening and closing stroke of the claw arm 5.

[0039] like Figure 5 and Figure 6 As shown, the surface of the pulley 8 contacts the curved track of the claw arm 5. When the claw arm opening and closing ring 4 moves vertically upward, the pulley 8 will push the curved track of the claw arm 5 toward the surface of the center column 3 through the lever action of the claw arm lock pin 7, thereby causing the claw arm 5 to open outward. When the claw arm opening and closing ring 4 moves vertically downward, the pulley 8 will also close the claw arm 5 through the lever action of the claw arm lock pin 7. When the claw arm opening and closing ring 4 drops to the lowest position, the inner diameter of the lower ring will naturally prevent the claw arm 5 from opening.

[0040] like Figure 7 As shown, the periphery of the claw arm opening and closing ring 4 is provided with a half-moon gear lock pin 9, a first half-moon lock pin 10, a second half-moon lock pin 11 and a driving gear 12. The half-moon gear lock pin 9, the first half-moon lock pin 10 and the second half-moon lock pin 11 are combined to form a ring, which surrounds the axis of the central column 3 and is driven by the electric motor and the driving gear 12 to swing back and forth in a clockwise and counterclockwise rotation. The clockwise and counterclockwise rotation and swinging operation of the half-moon joint lock pin ring group are all position controlled by a digital programming control system, but are not limited to the use of other forms of position control systems. The half-moon gear lock pin 9, the first half-moon lock pin 10 and the second half-moon lock pin 11 are all provided with a pin key 13, and the lower ring periphery of the claw arm opening and closing ring 4 is provided with a milling slot 14 to allow the pin key 13 to pass through.

[0041] like Figure 8 and Fig.11 As shown, the pin key 13 can rotate and swing back and forth at the bottom of the center column 3, and the cylindrical surface at the bottom of the center column 3 is provided with three vertical key slots 15. When the pin key 13 enters the range of the key slot 15, the claw arm opening and closing ring 4 can move upward. However, when the pin key 13 is not within the range of the key slot 15, the claw arm opening and closing ring 4 is blocked by the bottom of the center column 3 and cannot move upward, thus forming a pin arm effect.

[0042] like Figure 9-10 As shown, a hanging plate 17 is provided on the top of the modified central hanging column to provide a flat surface for the claw tip of the claw arm 5 to grab. A hanging ring 16 is also provided on the surface of the hanging plate 17. When necessary, a conventional hanging hook can be used to buckle on the hanging ring 16 to hang the creel. Fig. 9It is also shown that the claw tip of the claw arm 5 has a special hook-shaped design so as to be used to grab the flat surface of the hanging plate 17 of the central hanging column. The connecting section 18 is used to connect the hanging plate 17 and the central hanging column 19 (at Fig. 9 and Fig.10 The central sling 19 only shows a small section); the sling disc 17 and the sling ring 16 at the top of the central sling are both made of steel, and their size and shape are mainly designed considering the safety stress level generated by the weight of the hoisting load.

[0043] It should be understood that the above contents including the drawings are not limitations of the technical solution. In fact, any improvement of the technical solution based on the same or similar principles, including changes in the size, shape, and materials used in the structure, and replacement of components with similar functions, are within the technical solution claimed for protection by the present invention application.
