Description

Technical Field

[0001] This utility model relates to a wooden I-beam tilting and conveying mechanism, belonging to the technical field of wooden beam processing equipment. Background Technology

[0002] Timber I-beams, a common type of wooden structural component used in construction, are widely used in the building industry due to their unique "I"-shaped structure. They typically consist of a central web and two side flanges. This structural design allows timber I-beams to effectively reduce their weight while maintaining strength, thus improving material utilization efficiency.

[0003] Currently, in the production of traditional wooden I-beams, the pre-assembly of the web and side flanges is mainly done manually. However, manual assembly is slow and cannot meet production demands, resulting in very low production efficiency. Furthermore, manual assembly requires workers to maintain bent-over and raised-arm postures for extended periods, and involves constant handling and adjustment of the web and flanges, leading to high labor intensity.

[0004] To address the problems associated with manual assembly and meet actual production needs, a utility model patent with Chinese patent application number CN200920136768.6 discloses a wooden I-beam assembly machine. In operation, the upper and lower bearing surfaces, already coated with adhesive, are placed in a movable clamp for tenon jointing with the web. The web is then placed on a positioning plate, and friction conveying wheels gradually transport the wooden I-beam forward. Because the movable clamp is funnel-shaped, the upper and lower bearing surfaces are gradually compressed. The pre-formed wooden I-beam is then fed into a fixed clamp, also funnel-shaped, and transported forward in the same manner, thus being compressed and shaped. This method can replace manual assembly, improving production efficiency and reducing the labor intensity of operators.

[0005] However, the above-mentioned assembly machine still has the following problems in actual use:

[0006] When assembling the wooden I-beams, it is still necessary to manually flip the two side flanges and align them with the middle web before placing the aligned wooden I-beams into the assembly machine for tenoning and extrusion molding. It cannot achieve automatic flipping and conveying of the two side flanges and the middle web, resulting in low automation and high labor intensity for operators. Utility Model Content

[0007] In order to solve the above-mentioned problems existing in the prior art, this utility model provides a wooden I-beam flipping and conveying mechanism.

[0008] The technical solution of this utility model is as follows:

[0009] A wooden I-beam flipping and conveying mechanism includes a frame. The frame is provided with a first conveying mechanism for clamping and conveying flange plates and a second conveying mechanism for conveying web plates. The first conveying mechanisms are symmetrically arranged on the frame, and the second conveying mechanism is located between the two first conveying mechanisms. The frame is also provided with a flipping mechanism for flipping the first conveying mechanisms. By flipping the first conveying mechanisms, the flipping mechanism can flip the flange plates clamped by the first conveying mechanisms to form an assembly posture that adapts to the web plates.

[0010] The first conveying mechanism includes clamping and conveying assemblies evenly arranged along the length of the frame. Each clamping and conveying assembly includes a support body. A slide rail is provided on the front side wall of the support body, and a slider is slidably connected to the slide rail. A clamping hydraulic cylinder is also provided on the slider. The piston part of the clamping hydraulic cylinder is connected to the slider. The cylinder seat part of the clamping hydraulic cylinder is hinged to the top of the support body through a first hinge. A first auxiliary pressure roller is rotatably connected to the end of the slider away from the clamping hydraulic cylinder. A second auxiliary pressure roller is rotatably connected to the bottom of the support body. A transmission mechanism is provided in the middle of the support body. The transmission mechanism is formed by two bevel gears meshing perpendicularly to each other. A conveying roller is connected to the vertically arranged bevel gear through a connecting shaft. A spatial structure for clamping and conveying the flange plate is formed between the conveying roller, the first auxiliary pressure roller, and the second auxiliary pressure roller. The flange plate is located within the spatial structure. A transmission assembly is connected to the horizontally arranged bevel gear. The transmission assembly drives the bevel gears in each clamping and conveying assembly on the same side to move synchronously.

[0011] The transmission assembly includes a transmission motor mounted on the clamping and conveying assembly. The transmission motor is fixedly connected to one side wall of the support body of the first clamping and conveying assembly. A transmission rod is connected to the output of the transmission motor. The transmission rod passes through a bevel gear horizontally arranged in each clamping and conveying assembly located on the same side, thereby realizing the transmission connection of these bevel gears together.

[0012] The flipping mechanism and the first conveying mechanism are arranged in a one-to-one correspondence. The flipping mechanism includes a flipping motor fixedly mounted on the frame. A flipping rod is connected to the output of the flipping motor. A connection port is opened at the bottom of the support body in each clamping and conveying assembly. The flipping rod is fixedly connected to the clamping and conveying assembly at the corresponding position by passing through the connection port in each clamping and conveying assembly. When the flipping rod rotates, the clamping and conveying assembly at the corresponding position rotates accordingly.

[0013] The flipping mechanism further includes a flipping hydraulic cylinder mounted on the frame. The cylinder seat of the flipping hydraulic cylinder is hinged to the frame via a second hinge, and the piston of the flipping hydraulic cylinder is hinged to a support body in one of the clamping and conveying components via a third hinge.

[0014] The second conveying mechanism includes a profile support, the bottom of which is connected to the frame via a lifting assembly, and the top of which is provided with an I-beam support block, and the top of which is provided with symmetrically arranged flow strips.

[0015] The lifting assembly includes symmetrically arranged worm gear transmission seats. The worm bodies of both sides of the worm gear transmission seats are vertically arranged and their tops are fixedly connected to the profile bracket. The worm wheel parts of the two sides of the worm gear transmission seats are connected together by a linkage rod. A lifting motor is also provided on one side of the worm gear transmission seat, and the output part of the lifting motor is connected to the worm wheel part of the worm gear transmission seat on that side.

[0016] This utility model has the following beneficial effects:

[0017] This invention features a first conveying mechanism for clamping and conveying the flange plates and a second conveying mechanism for conveying the web plates, along with a flipping mechanism. In use, the first and second conveying mechanisms convey the flange plates and web plates. The flipping mechanism causes the first conveying mechanisms on both sides to flip, so that the flange plates are perpendicular to the web plates, forming an assembly posture compatible with the web plates. After this, the first and second conveying mechanisms feed the flange plates and web plates into subsequent assembly machinery, such as assembly machines, for the required assembly operation. Compared to existing technologies, this invention achieves automatic flipping and conveying of the two side flange plates and the middle web plate, enabling automatic assembly of wooden I-beams when used with assembly machines. It boasts advantages such as high automation and reduced operator workload. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Example: Please refer to Figures 1-5 This embodiment provides a wooden I-beam tilting and conveying mechanism, including a frame 1. The frame 1 is equipped with a first conveying mechanism 4 for clamping and conveying flange plates 2 and a second conveying mechanism 5 for conveying web plates 3. The conveying directions of both the first and second conveying mechanisms 4 and 5 are parallel to the length direction of the frame 1. The first conveying mechanisms 4 are symmetrically arranged vertically on the frame 1, and the second conveying mechanisms 5 are positioned between the two first conveying mechanisms 4 on either side. By arranging the first and second conveying mechanisms 4 and 5 as described above, the subsequent assembly of the flange plates 2 and web plates 3 can be facilitated.

[0033] The frame 1 is also provided with a flipping mechanism 6 for flipping the first conveying mechanism 4. The flipping mechanism 6 is arranged in a one-to-one correspondence with the first conveying mechanism 4. The flipping mechanism 6 can flip the flange plate 2 clamped by the first conveying mechanism 4 by flipping the corresponding first conveying mechanism 4, so as to adjust it to the assembly posture that is compatible with the web plate.

[0034] With the aforementioned setup, when assembling the wooden I-beams, the operator places the two side flange plates 2 into the corresponding first conveying mechanism 4 and the web plate 3 into the two side second conveying mechanisms 5. The first conveying mechanism 4 conveys the flange plates 2, and the second conveying mechanism 5 conveys the web plate 3. During this process, the operator controls the flipping mechanism 6 to flip the two side first conveying mechanisms 4 so that the flange plates 2 are flipped to be perpendicular to the web plate 3, so that the pre-cut slots on the two side flange plates 2 are aligned with the web plate 3. After this, the first conveying mechanism 4 and the second conveying mechanism 5 continue to convey the flange plates 2 and the web plate 3, and send the flange plates 2 and the web plate 3 into the subsequent existing technology such as the assembly machine for assembly, so that the required assembly operation can be carried out. The overall operation requires less manual intervention and has a high degree of automation.

[0035] In this embodiment, the first conveying mechanism 4 includes clamping and conveying assemblies 40 evenly arranged along the length of the frame 1. The number of clamping and conveying assemblies 40 can be selected according to actual conditions, such as the length of the wooden beams to be assembled, and is not limited here. The clamping and conveying assembly 40 includes a support body 401. A vertically arranged slide rail 402 is fixedly arranged on the front side wall of the support body 401. A slider 403 is slidably connected to the slide rail 402. A clamping hydraulic cylinder 404 is also arranged on the slider 403. The piston part of the clamping hydraulic cylinder 404 is fixedly connected to the slider 403. The cylinder seat part of the clamping hydraulic cylinder 404 is hinged to the top of the support body 401 by a first hinge 405. A first auxiliary pressure roller 406 is rotatably connected to the end of the slider 403 away from the clamping hydraulic cylinder 404. A second auxiliary pressure roller 407 is rotatably connected to the bottom of the support body 401. The projections of the first auxiliary pressure roller 406 and the second auxiliary pressure roller 407 are coincident. A transmission mechanism 408 is provided in the middle of the support body 401. The transmission mechanism 408 is formed by two bevel gears meshing perpendicularly with each other. Both bevel gears are rotatably connected to the middle position of the support body 401. A vertically arranged bevel gear is fixedly connected to a conveying roller 410 via a connecting shaft 409. When the vertically arranged bevel gear rotates, it drives the conveying roller 410 to rotate. The conveying roller 410, the first auxiliary pressure roller 406, and the second auxiliary pressure roller 407 form a spatial structure 411 for clamping and conveying the flange plate 2. The flange plate 2 is located within the spatial structure 411. When clamping and conveying the flange plate 2, the flange plate 2 is abutted against the first auxiliary pressure roller 406, the second auxiliary pressure roller 407, and the conveying roller 410. The first auxiliary pressure roller 406, under the action of the clamping piston rod, cooperates with the second auxiliary pressure roller 407 to clamp the flange plate 2 so that it is not easy to fall off. The conveying roller 410 rotates along with the vertically arranged bevel gear to convey the flange plate 2. A transmission assembly 42 is connected to a horizontally arranged bevel gear. The transmission assemblies 42 are symmetrically distributed on the frame 1. Both sides of the transmission assembly 42 can drive the bevel gear in each clamping and conveying assembly 40 located on the same side to move synchronously.

[0036] In this embodiment, the transmission assembly 42 includes a transmission motor 421 fixedly mounted on one of a plurality of clamping and conveying assemblies 40 located on the same side as it. Preferably, it is mounted in the clamping and conveying assembly 40 located in the middle to ensure the stability of the subsequent transmission rod 422. The transmission motor 421 is fixedly connected to one side wall of the support body 401 of this first clamping and conveying assembly 40. The output part of the transmission motor 421 is drivenly connected to the transmission rod 422. The transmission rod 422 is fixedly passed through the bevel gears arranged horizontally in each clamping and conveying assembly 40 located on the same side, thereby realizing the transmission connection of these bevel gears together.

[0037] With the aforementioned setup, when the first conveying mechanism 4 is in use, the operator places the flange plate 2 into the space structure 411, making it abut against the conveying roller 410. Then, the operator controls the clamping hydraulic cylinder 404 to start working. The clamping hydraulic cylinder 404 pushes the slider 403 to move along the slide rail 402, thereby driving the first auxiliary pressure roller 406 to move closer to the second auxiliary pressure roller 407, so as to clamp the flange plate 2 in the space structure 411. After that, the operator controls the drive motor 421 to start working. The drive motor 421, through the transmission rod 422, can drive the horizontally arranged bevel gear in each clamping and conveying assembly 40 to rotate, thereby driving the corresponding vertically arranged bevel gear to rotate, so that the conveying roller 410 rotates accordingly, so as to convey the flange plate 2 in the space structure 411.

[0038] In this embodiment, the flipping mechanism 6 includes a flipping motor 61 fixedly mounted on the frame 1. A flipping rod 62 is drivenly connected to the output of the flipping motor 61. Each clamping and conveying assembly 40 has a connection port 412 at its bottom. The flipping rod 62 is fixedly connected to the support body 401 of each clamping and conveying assembly 40 by passing through the connection port 412 of each clamping and conveying assembly 40 on its corresponding side. When the flipping rod 62 rotates, it causes each clamping and conveying assembly 40 to rotate along with it through the cooperation with the connection port 412, thereby realizing the flipping of the clamping and conveying assembly 40 and flipping the corresponding flange plate 2 to rotate it to a suitable position.

[0039] To improve the stability of the clamping and conveying assembly 40 during flipping, in this embodiment, the flipping mechanism 6 further includes a flipping hydraulic cylinder 63 mounted on the frame 1. The cylinder seat of the flipping hydraulic cylinder 63 is hinged to the frame 1 via a second hinge 64, and the piston of the flipping hydraulic cylinder 63 is hinged to the support body 401 of one of the clamping and conveying assemblies 40 located on its corresponding side via a third hinge 65. When the flipping hydraulic cylinder 63 rotates, it pushes the clamping and conveying assembly 40 to move, thereby driving all the clamping and conveying assemblies 40 located on its corresponding side to enter a flipping motion around the flipping rod 62. Combined with the operation of the flipping motor 61, it has two power sources for applying force, thus improving the stability of the clamping and conveying assembly 40 during flipping.

[0040] In this embodiment, the second conveying mechanism 5 includes a profile support 51. The profile support 51 is arranged in a direction that corresponds to the length direction of the frame 1. The bottom of the profile support 51 is connected to the frame 1 via a lifting assembly 52. ​​The top of the profile support 51 is provided with a plurality of I-beam support blocks 53 evenly arranged along the length direction of the profile support 51. The number of I-beam support blocks can be selected according to actual conditions and is not limited here. The top of the I-beam support blocks 53 is provided with symmetrically arranged flow strips 54. The flow strips 54 are arranged in a direction that corresponds to the length direction of the frame 1, and the web plate 3 is placed on the flow strips 54. With the aforementioned setup, during the conveying process, the web plate 3 can slide along the flow bar 54 under its own gravity (the flow bar 54 is a common conveying mechanism, and it has a certain tilt angle, mostly around 2 to 6 degrees. Therefore, the web plate 3 placed on the flow bar 54 can slide under its own gravity) to achieve the conveying of the web plate 3. Setting the second conveying mechanism 5 as a non-powered conveying mechanism can not only meet the conveying requirements of the web plate 3, but also reduce the power consumption of this flipping conveying mechanism during operation.

[0041] In this embodiment, the lifting assembly 52 includes worm gear transmission seats 521 arranged symmetrically on both sides, and the worm gear transmission seats 521 are mounted on the frame 1. The worm bodies 522 of both sides of the worm gear transmission seats 521 are vertically arranged and their tops are fixedly connected to the profile bracket 51. The worm wheel portions of the two sides of the worm gear transmission seats 521 are connected together by a linkage rod 523. A lifting motor 524 is also provided on one side of the worm gear transmission seat 521, and the output of the lifting motor 524 is connected to the worm wheel portion of the worm gear transmission seat 521 on that side. With the aforementioned setup, when the lifting motor 524 starts working, it can drive the worm gear transmission seat 521 to perform corresponding transmission, so that the two worm bodies 522 can move up and down accordingly. This can adjust the horizontal height of the profile bracket 51, thereby adjusting the horizontal height of the web plate 3. This enables the assembly of multi-size wooden beams. That is, by making the height of the web plate 3 adjustable, it can be well aligned with the slots pre-cut on the two side flange plates 2, thus enabling the assembly of multi-size wooden beams.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
