Description

Technical Field

[0001] This invention belongs to the field of U-shaped tube equipment, specifically relating to a fully automatic U-shaped tube loading device. Background Technology

[0002] After the U-shaped tubes are manufactured, they need to be placed on the corresponding U-shaped tube support frame. Currently, the storage of U-shaped tubes can only be done manually by inserting them into the tubes, and there is no corresponding mechanical automation equipment.

[0003] Due to the characteristics of the U-shaped tube structure, one end is a straight tube with parallel vertical alignment, and the other end is an arc shape. Therefore, during the conveying process, it is necessary not only to ensure the clamping and positioning of the U-shaped tube, but also to ensure that the clamping and positioning mechanism supporting the U-shaped tube does not obstruct the forward movement of the U-shaped tube when it is inserted into the U-shaped tube support frame.

[0004] Therefore, it is necessary to design a fully automatic U-shaped tube assembly device to solve the problems of low safety factor and slow assembly efficiency of traditional manual methods. Summary of the Invention

[0065] The loading platform and the conveyor frame are slidably mounted on the ground rail.

[0066] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0067] 1. By combining the pushing of the push rod mechanism with the clamping and positioning of the clamping mechanism, a U-shaped tube conveying method that replaces the traditional manual insertion method with a mechanical automated structure is realized. Furthermore, by adjusting the displacement of the clamping mechanism, the problem of the push rod mechanism being unable to continue moving forward when the arc end of the U-shaped tube is conveyed to the clamping mechanism is avoided.

[0068] 2. By setting up a moving beam structure, it is possible to meet the needs of conveying U-shaped pipes of different widths and adjusting different conveying positions, thereby greatly improving the overall applicability of the equipment.

[0069] 3. By optimizing the structure of the push rod mechanism, it is made to be adjustable in both the longitudinal and lateral directions. Together with the push rod guide rail on the conveyor frame, it forms a two-stage horizontal progressive adjustment and a one-stage longitudinal position adjustment method, which can better convey the U-shaped tube and center it with the arc end of the U-shaped tube, ensuring the reliability and stability of the conveying process.

[0070] 4. By optimizing the clamping mechanism, a telescopic structure can be adopted to avoid affecting the conveying of the U-shaped tube. Alternatively, a folding structure can be used, as in the feeding clamping mechanism of this application. Both structural designs prevent the push rod mechanism from obstructing further movement when the curved end of the U-shaped tube reaches the clamping mechanism. Preferably, a telescopic clamping mechanism, combined with a pressure roller flipping mechanism, enables rapid overall lifting of the U-shaped tube, facilitating rapid loading and unloading alternation with the corresponding U-shaped tube feeding device.

[0071] 5. By optimizing the U-shaped tube feeding device, specifically adopting a flipping method, the operator can directly place the U-shaped tube on the flipping frame by horizontal hoisting or transportation, then clamp and position the U-shaped tube accordingly, and then adjust it from a horizontal state to a vertical state by rotating the flipping frame. Finally, the U-shaped tube is placed on the conveyor frame by overall transportation. By combining its overall structure, the integrated fully automatic tube loading operation is finally realized.

[0072] 6. By rationally and effectively setting the structural layout and drive method, the reliability and accuracy of the equipment during operation are greatly improved. Attached Figure Description

Detailed Implementation

[0081] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described and illustrated below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments provided by this invention without inventive effort are within the scope of protection of this invention.

[0082] Obviously, the accompanying drawings described below are merely some examples or embodiments of the present invention. Those skilled in the art can apply the present invention to other similar scenarios based on these drawings without any inventive effort. Furthermore, it is understood that although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content disclosed in this invention, modifications to design, manufacturing, or production based on the technical content disclosed in this invention are merely conventional technical means and should not be construed as insufficient disclosure of the present invention.

[0083] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention may be combined with other embodiments without conflict.

[0084] An automatic U-shaped tube loading device includes: a conveying frame 1, a push rod mechanism 2, and a clamping mechanism 3; wherein, the push rod mechanism 2 is used to push the arc-shaped end of the U-shaped tube and slides on the conveying frame 1; the clamping mechanism 3 is used to clamp the straight end of the U-shaped tube and is located at the path of the push rod mechanism 2; the push rod mechanism 2 passes through the clamping mechanism 3, and the clamping mechanism 3 adjusts its displacement to make room for the conveying of the U-shaped tube, thereby avoiding the clamping mechanism 3 from obstructing the conveying of the U-shaped tube on the conveying frame 1.

[0085] The U-shaped tube to be installed is placed on the clamping mechanism 3 for clamping and positioning. Then, the clamped and positioned U-shaped tube is pushed by the push rod mechanism 2. When the arc end (closed structure) of the U-shaped tube reaches the adjacent clamping mechanism 3, the clamping mechanism 3 is adjusted by displacement to avoid obstructing the movement of the U-shaped tube and the push rod mechanism 2, and to provide space for movement.

[0086] Because the actual dimensions and width of the U-shaped tubes vary, and their positions on the U-shaped tube support frame also differ, in some embodiments, to address these issues, the upper moving beam 101 and the lower moving beam 102 are arranged in parallel and slidably mounted on the conveyor frame 1 via the moving beam guide rail 103; clamping mechanisms 3 are mounted on the upper moving beam 101 and the lower moving beam 102; multiple clamping mechanisms 3 are provided on both the upper moving beam 101 and the lower moving beam 102, and preferably, a staggered vertical arrangement is adopted, as shown below. Figure 1 As shown, the above-mentioned configuration ensures reliable support for the straight end of the U-shaped tube and correspondingly reduces the number of clamping mechanisms 3, thereby lowering the manufacturing cost of the equipment. Specifically, the upper moving beam 101 and the lower moving beam 102 are driven by a moving beam drive mechanism 104, and there are various driving methods. Preferably, the moving beam drive mechanism 104 is located between the upper moving beam 101 and the conveyor frame 1, and between the lower moving beam 102 and the conveyor frame 1. Specifically, a lead screw motor is used for driving, which drives the upper moving beam 101 and the lower moving beam 102 to adjust their vertical positions. This method offers high precision, and the lead screw's inherent locking mechanism also ensures high safety and stability.

[0087] Since the upper beam 101 and lower beam 102 have been adjusted in position, if the push rod mechanism 2 cannot ensure that its push rod part is aligned with the arc end of the U-shaped tube, it may lead to uneven force during the pushing process. Since the straight end of the U-shaped tube is generally long, it is inevitable that it will undergo certain material deformation due to gravity. Therefore, in order to ensure the safety and reliability of the pushing process, in some embodiments, the push rod mechanism 2 includes: a push rod seat 201, a vertical push seat 202, and a horizontal push seat 203; wherein, the push rod seat 201 is slidably mounted on the conveyor frame 1 via the push rod guide rail 105; the vertical push seat 202 is slidably mounted on the push rod seat 201 via the vertical guide rail 204; the horizontal push seat 203 is slidably mounted on the vertical push seat 202 via the horizontal guide rail 205; the horizontal guide rail 205 and the vertical guide rail 204 are vertically arranged; the horizontal guide rail 205 and the push rod guide rail 105 are parallel to each other.

[0088] The push rod seat 201 can first be adjusted horizontally on the conveyor frame 1. When the pushing position is insufficient, a second horizontal adjustment is performed using the horizontal push seat 203. The vertical push seat 202 is mainly used for centering, ensuring the stability and balance of the force. Preferably, a corresponding elastic buffer layer can be provided at the front end of the horizontal push seat 203 to buffer the compression.

[0089] To address the driving issues of the push rod mechanism 2 in actual operation, some implementation methods have incorporated optimized designs to ensure its reliability and accuracy. Specifically, the push rod mechanism 2 further includes: a push rod seat pushing mechanism, a vertical push rod seat pushing mechanism, and a horizontal push rod seat pushing mechanism; the push rod seat pushing mechanism is located between the conveyor frame 1 and the push rod seat 201; the vertical push rod seat pushing mechanism is located between the push rod seat 201 and the vertical push rod seat 202; and the horizontal push rod seat pushing mechanism is located between the horizontal push rod seat 203 and the vertical push rod seat 202.

[0090] Preferably, the push rod seat pushing mechanism further includes: a drive shaft 214, which is rotatably mounted on the push rod seat 201, and is provided with a linkage gear 212 and a travel gear 213; a push rod seat drive motor 210, which is mounted on the push rod seat 201, and is provided with a drive gear 211 at its drive end; the drive gear 211 meshes with the linkage gear 212; and a rack guide rail 106, which is mounted on the conveyor frame 1, and is meshed with the travel gear 213 and the rack guide rail 106.

[0091] The push rod seat here uses a gear and rack structure, mainly considering the overall length of the U-shaped tube. Although other driving methods and structures can also achieve the motion effect, their stability and reliability are poor. For example, if a push cylinder is used, the length of the cylinder's drive shaft is difficult to meet the actual application. If a rope winder is used, its control accuracy is not high.

[0092] Preferably, the vertical pusher mechanism further includes: a vertical drive motor 206, which is mounted on the pusher seat 201; and a vertical lead screw 208 connected to the vertical drive motor 206 is threadedly connected to the horizontal pusher 203.

[0093] Preferably, the horizontal pusher mechanism further includes: a horizontal drive motor 207, which is mounted on the horizontal pusher 203; a horizontal lead screw 209 connected to the horizontal drive motor 207 is threadedly connected to the vertical pusher 202.

[0094] Both the vertical pusher mechanism and the horizontal pusher mechanism are adjusted using a threaded structure. Similarly, other drive structures, such as cylinders, hydraulic cylinders, electric cylinders, and rope winders, can also be used. However, considering accuracy and cost, a lead screw is preferred. To avoid mutual interference during operation, the vertical lead screw 208 and the horizontal lead screw 209 are preferably located on opposite sides of the vertical pusher 202.

[0095] The clamping mechanism 3 not only needs to clamp and position the branch end of the U-shaped tube, but also needs to ensure that it does not affect the normal transport of the U-shaped tube. Therefore, two structural methods can be adopted to avoid its impact on the U-shaped tube.

[0096] The first specific type of clamping mechanism 3 is a telescopic structure.

[0097] Specifically, the clamping mechanism 3 includes: a mounting base 301, a pressure roller slide 302, a pressure wheel slide 303, a pressure roller 306, a pressure wheel shaft 307, and a pressure wheel 308. The pressure roller slide 302 and the pressure wheel slide 303 are slidably mounted on the mounting base 301 via the pressure roller guide rail 304 and the pressure wheel guide rail 305, respectively. The pressure roller 306 and the pressure wheel shaft 307 are respectively located at the outer ends of the pressure roller slide 302 and the pressure wheel slide 303, and the pressure roller 306 and the pressure wheel shaft 307 are arranged in parallel. The pressure wheel 308 is located on one side of the pressure wheel shaft 307 and can rotate relative to the mounting positions of the pressure roller slide 303 and the pressure wheel shaft 307. Several annular grooves are evenly distributed on the pressure wheel 308. Through the structure of the annular grooves, multiple U-shaped tubes can be clamped simultaneously and separated individually to ensure the stability and reliability of the clamping.

[0098] With the above settings, the pressure roller 306 and pressure wheel 308 can be retracted as a whole. At the same time, the rotation of the pressure wheel 308 can not only clamp with the pressure roller 306, but also lift or lower the U-shaped tube as a whole, greatly improving the loading and unloading efficiency between the clamping mechanism 3 and the U-shaped tube feeding device.

[0099] In some embodiments, the clamping mechanism 3 further includes: a pressure roller slide pushing mechanism, a pressure wheel slide pushing mechanism, and a pressure wheel flipping mechanism 309; the pressure roller slide pushing mechanism is located between the mounting base 301 and the pressure roller slide 302; the pressure wheel slide pushing mechanism is located between the mounting base 301 and the pressure wheel slide 303; the pressure wheel flipping mechanism 309 is hinged between the pressure wheel 308 and the pressure wheel slide 303 or hinged between the pressure wheel shaft 307 and the pressure wheel slide 303. In practice, it is usually necessary to adjust the pressure wheel 308 to a 90° position, i.e., to keep it horizontal or perpendicular to the pressure wheel shaft 307. Therefore, when the pressure wheel 308 is fixed to the pressure wheel shaft 307, this can be achieved by rotating the pressure wheel shaft 307; when the pressure wheel 308 is rotatably connected to the pressure wheel shaft 307, this can be achieved by rotating the pressure wheel 308.

[0100] Preferably, the pressure roller slide pushing mechanism further includes: a pressure roller drive motor 310, the pressure roller drive motor 310 is mounted on the mounting base 301, and the lead screw connected to the pressure roller drive motor 310 is threadedly connected to the pressure roller slide 302.

[0101] Preferably, the pressure roller slide pushing mechanism further includes: a pressure roller drive motor 311, which is mounted on the mounting base 301, and the lead screw connected to the pressure roller drive motor 311 is threadedly connected to the pressure roller slide 303.

[0102] Similarly, both the pressure roller slide pushing mechanism and the pressure wheel slide pushing mechanism are adjusted using a threaded structure. Other driving structures, such as cylinders, hydraulic cylinders, electric cylinders, and rope winders, can also be used.

[0103] Preferably, the pressure roller tilting mechanism 309 is a pneumatic cylinder, a hydraulic cylinder, or an electric pusher cylinder.

[0104] The second specific type of clamping mechanism 3 is a folding structure.

[0105] Specifically, the clamping mechanism 3 can refer to the setting of the feeding clamping mechanism in this application, and the whole can be retracted by folding and unfolding.

[0106] In actual use, another problem that needs to be solved is how to place the U-shaped tube on the clamping mechanism 3. Therefore, a corresponding U-shaped tube feeding device is also needed.

[0107] The U-shaped tube feeding device further includes: a feeding platform 401, a feeding slide 402, a tilting frame 403, a feeding guide rail 404, a feeding clamping mechanism, a feeding clamping drive mechanism, and a tilting frame drive mechanism 412; the feeding slide 402 is slidably mounted on the feeding platform 401; the tilting frame 403 is hinged to one side of the feeding slide 402, so that the feeding slide 402 can be tilted from a horizontal state to a vertical state; the feeding guide rail 404 is mounted on the tilting frame 403; the feeding clamping mechanism is mounted on the feeding guide rail 404; the feeding clamping drive mechanism is located between the feeding clamping mechanism and the tilting frame 403; and the tilting frame drive mechanism 412 is located between the feeding slide 402 and the tilting frame 403.

[0108] The flipping frame drive mechanism 412 is used to realize the relative rotation of the flipping frame 403. The operator places the U-shaped tube horizontally on the flipping frame 403 in a horizontal state, and then clamps and positions it through the feeding clamping mechanism. Then, it is flipped to a vertical state, and the U-shaped tube is placed on the clamping mechanism 3 as a whole.

[0109] In some embodiments, the feeding clamping mechanism includes: a feeding clamping seat 405, a first hinge plate 406, a second hinge plate 407, a roller 408, a wheel 409, a roller driving mechanism 410, and a wheel driving mechanism 411. The first hinge plate 406 and the second hinge plate 407 are arranged in parallel and hinged to each other on the feeding clamping seat 405. The roller 408 and the wheel 409 are respectively disposed at one end of the first hinge plate 406 and the second hinge plate 407. The roller driving mechanism 410 and the wheel driving mechanism 411 are respectively hinged between the other end of the first hinge plate 406 and the second hinge plate 407 and the feeding clamping seat 405. The roller 409 has a plurality of annular grooves evenly distributed on it. Through the structure of the annular grooves, multiple U-shaped tubes can be clamped simultaneously and separated individually to ensure the stability and reliability of the clamping. Similarly, the structure of the feeding clamping mechanism in this application can also adopt the mechanical structure of the clamping mechanism 3 in this application.

[0110] First, the tilting frame 403 is in a horizontal position, and the U-shaped tubes are placed horizontally (i.e., both straight ends of the U-shaped tubes are on the same side of their corresponding rollers 409). Then, the U-shaped tubes are placed one by one, starting from the bottommost annular groove. After the first U-shaped tube is placed, the angle of the roller 408 is adjusted by the roller drive mechanism 410, so that the roller 408 and the innermost annular groove are relatively closed. This process is repeated until the U-shaped tube is installed in the outermost annular groove. Finally, the roller 408 and the roller 409 are relatively aligned, thus clamping and locking all the U-shaped tubes in the annular grooves. After the initial installation is completed, the tilting frame 403 is changed from a horizontal to a vertical position by the tilting frame drive mechanism 412, and then the entire frame can be moved to the designated position by moving the loading slide 402.

[0111] The tilting frame drive mechanism 412, the roller drive mechanism 410, and the wheel drive mechanism 411 are cylinders, hydraulic cylinders, or electric push cylinders; the loading clamping drive mechanism further includes: a loading clamping motor 413, which is mounted on the tilting frame 403, and the lead screw connected to the loading clamping motor 413 is threadedly connected to the loading clamping seat 405.

[0112] In some embodiments, it also includes: a ground rail 5; a feeding platform 401 and a conveyor frame 1 are slidably mounted on the ground rail 5.

[0113] Its working principle is as follows:

[0114] Several U-shaped tubes are installed between rollers 408 and 409 in the U-shaped tube feeding device, and the U-shaped tubes are individually clamped and positioned by the annular grooves on the rollers 409. Then, they are transported to the conveyor frame 1 with the help of the ground rail 5.

[0115] At this time, the pressure roller 306 of the clamping mechanism 3 on the conveyor frame 1 retracts. The handover of the U-shaped tube is ensured by adjusting the positions of the upper moving beam 101, the lower moving beam 102, and the feeding clamping mechanism. The U-shaped tube is placed on the pressure roller shaft 307, which then flips to lift the U-shaped tube. At the same time, the pressure roller 306 extends, completing the alternating clamping of the U-shaped tube. The U-shaped tube feeding device resets and returns to its initial state, ready for the next process.

[0116] The clamped U-shaped tube is pushed by the horizontal push seat 203 on the push rod mechanism 2. When it is moved to the corresponding clamping mechanism 3, the pressure roller 306 and pressure wheel 308 retract at the same time, providing the corresponding forward space for the arc end of the U-shaped tube and the push rod mechanism 2, so as to ensure the normal use of the equipment.

[0117] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
