[0002] The yarn drum is mainly a workpiece that provides a bearing platform for the fine yarn that has been twisted into fine yarn through multiple processes. The yarn drum itself is heavy. When the yarn is wound on the yarn drum, its total weight will exceed the manual handling capacity. Therefore, it is necessary to set up a specific automatic lifting device for loading and unloading.

[0003] Traditional yarn reels are usually installed manually, but the reel head is heavy, which requires a certain amount of physical strength from the installer, making it difficult and dangerous to install. Currently, there are also equipment that uses automatic lifting mechanisms to assist the reel head in lifting and lowering to facilitate the loading and unloading of yarn reels, such as:

However, the lifting mechanism can only lift the pan head to a certain height to assist workers in installing the pan head. It does not have a pan head advancement mechanism, and the installation is still inconvenient.

[0005] In view of this, it is urgently necessary to provide an automatic lifting device for assembling and unassembling the yarn bobbin to solve the above problems. Utility Model Content

[0034] An automatic lifting device for facilitating the loading and unloading of yarn bobbins provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Combine Figure 1-Figure 5 As shown, the utility model provides an automatic lifting device for facilitating the loading and unloading of yarn disk heads, comprising a plurality of yarn disk heads 100, a traction mechanism 200 for transporting the yarn disk heads 100, a reciprocating mechanism 300 installed on the traction mechanism 200, and a non-obstructive clamping mechanism 400 for lifting the yarn disk heads 100. The traction mechanism 200 is used to carry yarn disks that are empty or fully loaded with yarn, the reciprocating mechanism 300 is used to provide stable lifting and reciprocating motive force to the non-obstructive clamping mechanism 400, and the non-obstructive clamping mechanism 400 is used to clamp yarn disks that are empty or fully loaded with yarn.

[0037] The traction mechanism 200 includes a rail-type base 210, wheels 220, end plates 230, vertical rods 240, guide components 250, clamping seats 260, transmission components 270, winding rollers 280 and cables 290; the reciprocating mechanism 300 includes a slide 310, a first hydraulic component 320, an inclined frame 330, a support plate 340, a slider 350, a clamp 360, a clamp 370 and a second hydraulic component 380; the unobstructed clamping mechanism 400 includes a load-bearing frame 410, a column 420, an adapter 430, a clamping arm 440, a limiting cross bar 450, a return spring 460 and a beam frame 470.

[0038] The traction mechanism 200 includes a guide assembly 250, a track-type base 210 that carries multiple yarn heads 100, two end plates 230 mounted on the track-type base 210, two vertical rods 240 mounted in the two end plates 230, four wheels 220 evenly distributed at the bottom of the track-type base 210, two clamping seats 260 fixedly mounted on the track-type base 210, a transmission assembly 270 fixedly mounted on one of the clamping seats 260, a winding roller 280 movably mounted in the two clamping seats 260, and a cable 290 wound around the winding roller 280.

[0039] The reciprocating mechanism 300 includes a slide 310 movably mounted on two vertical rods 240, a support plate 340 disposed on top of the slide 310, a slider 350 mounted on the bottom of the support plate 340, a first hydraulic component 320 fixedly mounted on one end of the slide 310, a clamp 360 fixedly mounted on the support plate 340, an inclined frame 330 movably connected to the top of the hydraulic sub-rod in the first hydraulic component 320 and the clamp 360, two clamps 370 fixedly mounted inside the support plate 340, and a second hydraulic component 380 mounted inside the two clamps 370;

[0040] The unobstructed clamping mechanism 400 includes four beams 470, a return spring 460 installed inside the support plate 340, two limiting cross bars 450 installed at both ends of the return spring 460, two sets of clamping force arms 440 arranged on the two limiting cross bars 450, a load-bearing frame 410 connected to the top of the hydraulic sub-rod in the second hydraulic component 380, two columns 420 fixedly installed at both ends of the load-bearing frame 410, and an adapter 430 installed at the bottom end of the column 420.

[0041] Spinning is the act of twisting shorter fibers to form a continuous, infinitely extending thread or yarn that can be used to weave cloth. All spinning machines only do two things: first, they aggregate a large number of short fibers into loose strips, and then pull out the strips little by little and twist them into fine coarse yarn. The coarse yarn becomes longer through twisting to form fine yarn. With the development of mechanical technology, the spinning process has gradually been replaced by machinery instead of manual labor. After processing is completed, the yarn needs to be wound onto a yarn reel, and the yarn reel itself is heavy. The weight of a yarn reel full of yarn will exceed the ability of manual handling and lifting.

[0042] At this time, the device can provide the yarn disc head 100 with automatic lifting and assembly capabilities without causing obstruction at both ends of the yarn disc head 100, thereby facilitating the quick connection of the fixed pin and the movable pin toward the two ends of the yarn disc head 100.

[0043] Example 2:

[0044] Combine Figure 1-Figure 3 As shown, based on Example 1, the track-type base 210 is composed of two horizontal rails and two sets of reinforcing ribs installed on the two horizontal rails, and the top of the horizontal rail is provided with a groove adapted to constrain the yarn disk head 100;

[0045] The wheel 220 is composed of a U-shaped shell and a load-bearing wheel;

[0046] The transmission assembly 270 is composed of a chassis and a motor, and a gear plate adapted to mesh with the ring gear at one end of the winding roller 280 is installed on the transmission shaft inside the motor;

[0047] The guide assembly 250 consists of two L-shaped pads, a guide rod, and a guide wheel movably mounted in the middle of the guide rod using a bearing;

[0048] The cable 290 passes through the annular groove outside the guide wheel.

[0049] The traction vehicle is used to drive the rail-type base 210 to move along the indoor floor, and the unobstructed clamping mechanism 400 is pushed toward the yarn rack. As the yarn disk head 100 is moved as a whole to the designated yarn rack indoors, the internal motor of the transmission component 270 is running, and its internal transmission shaft will cooperate with the gear to drive the winding roller 280 to rotate, and the cable 290 will drive the support plate 340 to provide stable traction force. At the same time, the two symmetrically arranged vertical rods 240 can provide sufficient compressive restraint force for the stable lifting of the support plate 340. Finally, the stable lifting unobstructed clamping mechanism 400 can quickly and safely load and unload each yarn disk head 100 under the lifting of the recursive mechanism 300.

[0050] Example 3:

[0051] Combine Figure 2-Figure 5 As shown, based on Example 1, the slide 310 is a cross-shaped structure as a whole, and a cross-shaped slideway is opened in the plate in the middle of the slide 310, and the slider 350 is adapted to be clamped in the cross-shaped slideway;

[0052] A rectangular through hole is defined at one end of the support plate 340 away from the slider 350 , and the return spring 460 is installed in the rectangular through hole.

[0053] According to the loading and unloading requirements of the empty or fully wound yarn drum, when the empty yarn drum is removed from the yarn rack, the second hydraulic component 380 is operated in advance, and the two sets of clamping force arms 440 under pressure and traction can quickly clamp the empty yarn drum and remove it from the yarn rack. As the first hydraulic component 320 operates, the support plate 340 pulled by the inclined frame 330 can evacuate the hoisted empty yarn drum from the yarn rack, and finally the empty yarn rack can be quickly removed;

[0054] According to the above-mentioned steps for removing the empty yarn disk, when it is necessary to quickly install the yarn disk full of yarn onto the yarn rack, the reverse operation of the above steps can automatically assemble the yarn disks full of yarn evenly distributed on the track-type base 210 on the yarn rack, thereby reducing the manual labor intensity and ensuring the safety of workers.

[0055] Example 4:

[0056] Combine Figure 3-Figure 5 As shown, based on the above embodiment, the unobstructed clamping mechanism 400 further includes four beams 470;

[0057] One end of the beam 470 is fixedly mounted on the end surface of the return spring 460 , and the other end of the beam 470 is adapted to bear pressure on the clamping arm 440 ;

[0058] The clamping force arm 440 is composed of a bent clamping rod, a fan-shaped reinforcement frame, and a fan-shaped rubber pad installed inside the fan-shaped reinforcement frame.

[0059] By operating the second hydraulic component 380, as the internal hydraulic sub-rod rises and falls, the load-bearing frame 410 installed on the top of the hydraulic sub-rod can apply balanced pressure to the two columns 420 and the adapter 430. As the two sets of clamping force arms 440 are under pressure, the two sets of clamping force arms 440 supported by the two limiting cross bars 450 can adaptively clamp the empty or fully wound yarn reel at the moment of force, and the reel head of the yarn reel can be fixed without obstruction, and the lifted yarn reel will not cause any obstruction to the assembly of the fixed pin or the movable pin.

[0060] The working principle and usage process of the present invention are as follows: according to the replacement demand of the yarn reel on the yarn rack, when the yarn reel on the yarn rack is empty and needs to be replaced, the worker can drive a traction vehicle such as a forklift to drive the traction mechanism 200 as a whole to approach the yarn rack until the unobstructed clamping mechanism 400 is facing the assembly direction of the yarn reel, and then run the motor in the transmission assembly 270. At this time, the transmission shaft inside the motor will cooperate with the gear transmission winding roller 280, and the cable 290 will be wound on the winding roller 280. At this time, the pulled recursive mechanism 300 and the unobstructed clamping mechanism 400 can be lifted as a whole toward the position where the yarn rack is to be assembled, until the unobstructed clamping mechanism 400 rises to the specified position, and then the first hydraulic component 320 can be controlled to operate. When the hydraulic sub-rod in the first hydraulic component 320 contracts downward When the chuck 360 and the support plate 340 pushed by the inclined frame 330 will drive the unobstructed clamping mechanism 400 to be pushed toward the position to be assembled on the yarn rack until the unobstructed clamping mechanism 400 moves to the top of the position to be assembled, and then the second hydraulic component 380 is operated until the hydraulic sub-rod in the second hydraulic component 380 contracts downward, and the load-bearing frame 410 applies pressure to the two columns 420 and the two sets of clamping force arms 440 to expand at the same speed until the two sets of clamping force arms 440 position and clamp the two ends of the yarn disk head 100. After the hydraulic sub-rod in the second hydraulic component 380 extends upward, the two sets of clamping force arms 440 can clamp the disk heads at both ends of the yarn disk head 100, and finally the clamped yarn disk head 100 is lifted and transferred to the track-type base 210 according to the above operation method.

[0061] Similarly, when each yarn disk head 100 is fully wound with yarn and waiting to be assembled, the device can push each yarn disk head 100 fully wound with yarn toward the assembly position of the yarn rack in the above manner. At this time, the device can safely load and unload the yarn disk head 100 while reducing the interference of the suspended yarn disk head 100 on the fixed pin and the movable pin.

[0062] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
