Description

Technical Field

[0001] This application relates to the technical field of flipping machines, and in particular to an in-situ flipping machine. Background Technology

[0002] In automated processing of sheet materials (such as woodworking, furniture production, and building material processing), it is often necessary to flip the sheets to facilitate double-sided processing or to interlock and glue two sheets together. The sheet flipping machine, as the core equipment for achieving this operation, plays a crucial role in improving production efficiency and automation.

[0003] Currently, existing sheet metal flipping equipment on the market typically employs large-span rotary mechanisms or relies on long production lines to complete the flipping and conveying of sheets. This traditional flipping equipment often requires a significant amount of transverse space in the workshop during continuous operation, resulting in low space utilization and increased site costs for businesses. Furthermore, existing flipping mechanisms are prone to instability and vibration when gripping and flipping heavy or large sheets due to uneven force distribution in the mechanical structure or limitations in the transmission method. When bonding two sheets, the lack of effective guiding and centering correction mechanisms often leads to poor bonding accuracy and misalignment, making it difficult to meet the demands of high-quality continuous operation.

[0004] Therefore, in order to overcome the above-mentioned defects in the existing technology, how to design an in-situ flipping machine that can make full use of vertical space to effectively reduce the space occupied by the equipment, and significantly improve the stability of plate flipping, conveying and bonding, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In order to reduce the space occupied by the equipment and improve the stability of the board flipping, this application provides an in-situ board flipping machine.

[0006] This application provides an in-situ flipping machine, which adopts the following technical solution:

[0007] A type of in-situ flipping machine includes a base frame. Two layers of horizontal frames are arranged on the top surface of the base frame. Multiple conveyor rollers are spaced apart on the top surfaces of the two horizontal frames. A vertical frame assembly is arranged on one side of the base frame. A main beam is arranged on one side of the vertical frame assembly. Multiple main arms are spaced apart on one side of the main beam. A flipping arm is arranged at one end of each main arm. The multiple flipping arms are staggered with the multiple conveyor rollers. The main beam is equipped with a flipping component for simultaneously driving the multiple flipping arms to flip. Each flipping arm is equipped with a suction cup assembly. The vertical frame assembly is equipped with a lifting component for raising and lowering the main beam.

[0008] By adopting the above technical solution, during continuous operation of the flipping machine, the main arm and flipping arm are first lowered below the conveyor rollers by the lifting assembly. After the first board is conveyed onto the conveyor rollers of the upper crossbeam, the main arm and flipping arm are lifted by the lifting assembly. At this time, the flipping arm lifts the first board, and the suction cup group fixes the first board with negative pressure. Then, the second board is conveyed onto the upper crossbeam. After the second board is in place, the flipping assembly is activated. The flipping assembly simultaneously drives multiple flipping arms to flip. The multiple flipping arms together drive the first board to flip 180 degrees through the suction cup group. Finally, the lifting assembly drives the first board to descend until the two boards are glued together. This process is repeated. By utilizing the upper space to complete the flipping of the boards, not only is manual work reduced, but the space occupied in the horizontal area is also reduced, which helps to improve the timeliness of board flipping.

[0009] Optionally, the lifting assembly includes a main shaft rotatably mounted on the top surface of the upright assembly, the main shaft being driven by a chain gear transmission assembly, a main beam being guided and lifted on one side of the upright assembly, and the main beam being fixedly connected to one side of the chain gear transmission assembly, a counterweight being guided and lifted on the other side of the upright assembly, and the counterweight being fixedly connected to the other side of the chain gear transmission assembly, and the upright assembly being provided with a first driving member for driving the main shaft to rotate.

[0010] By adopting the above technical solution, when the first driving component drives the main shaft to rotate, the main shaft drives the chain gear transmission group to drive. The counterweight is used to balance the gravity when lifting the plate and avoid the chain gear transmission group from skipping teeth. Under the action of the chain gear transmission group, the chain gear transmission group drives the main beam to rise and fall. The main beam simultaneously drives multiple main arms and tilting arms to rise and fall, which helps to improve the stability of lifting and falling the plate.

[0011] Optionally, the tilting assembly includes a drive shaft that passes through and is rotatably connected to multiple main arms. The inner side of each main arm and one side of the middle of the tilting arm are connected to a synchronous pulley. The main beam is provided with a second drive component for driving the drive shaft to rotate.

[0012] By adopting the above technical solution, when the second driving component drives the transmission shaft to rotate, the transmission shaft drives multiple flipping arms to flip simultaneously through the synchronous pulleys. At this time, the multiple flipping arms rotate synchronously and drive the plate to flip 180 degrees through the suction cup assembly, which helps to improve the stability of the plate flipping.

[0013] Optionally, the inner side of the cross frame is provided with a vertical bearing seat, and a horizontal shaft is rotatably connected inside the vertical bearing seat. The horizontal shaft is driven by an elastic flat belt connected to each of the conveying rollers. The elastic flat belt is a Möbius strip structure. The cross frame is provided with a third driving component for driving the horizontal shaft to rotate, and the cross frame is provided with an adjusting component for adjusting the tension of the elastic flat belt.

[0014] By adopting the above technical solution, when the third driving component drives the horizontal shaft to rotate, the horizontal shaft simultaneously drives multiple elastic flat belts. At this time, each elastic flat belt drives the corresponding conveyor roller to rotate independently. Compared with gear chain belt transmission, this not only helps to reduce the noise generated during transmission, but also helps to independently adjust the spacing between each conveyor roller, thereby improving the stability of the sheet material being conveyed on the conveyor roller.

[0015] Optionally, the adjusting assembly includes a screw, a slider is provided on one side of the crossbeam with a vertical bearing, a vertical hole is provided on one side of the crossbeam corresponding to the position of the slider, the slider is slidably connected in the vertical hole, the screw is rotatably connected to the outside of the crossbeam, and the screw is threadedly connected to the slider.

[0016] By adopting the above technical solution, when it is necessary to adjust the tension of the elastic flat belt, the screw is driven to rotate. Under the restriction of the vertical hole, the screw drives the slider to rise and fall within the vertical hole. The slider drives the vertical bearing to rise and fall, and the vertical bearing drives the horizontal shaft to rise and fall. The horizontal shaft then adjusts the tension of the elastic flat belt, ensuring the stability of the conveyor roller transmission.

[0017] Optionally, a support frame is provided on the inner side of the cross frame, and a clamping crossbar is symmetrically slidably arranged on the top surface of the support frame. Multiple clamping plates are provided on the top surface of the clamping crossbar, and the cross frame is provided with a drive assembly for driving the two symmetrical clamping crossbars to move towards each other.

[0018] By adopting the above technical solution, the opposing clamps are used to centrally transport the plate on the conveying roller. The spacing between the opposing clamps is adjusted according to the specifications of the plate. At this time, the drive assembly drives the two clamping bars to move towards each other, and the two clamping bars then drive the clamps to move towards each other, which helps to improve the applicability of the flipping machine.

[0019] Optionally, the drive assembly includes a cylinder and a rack and pinion drive assembly, both of which are disposed on the top surface of the support frame. The telescopic end of the cylinder is connected to one of the clamping crossbars, and both ends of the rack and pinion drive assembly are connected to two symmetrical clamping crossbars.

[0020] By adopting the above technical solution, when the cylinder is started, the cylinder drives one of the clamping bars to move through the telescopic end. At the same time, one of the clamping bars drives the other clamping bar to move in the opposite direction through the gear and rack transmission group, which facilitates the convenience of adjusting the distance between the opposing clamping plates according to the actual specifications of the plate.

[0021] Optionally, each of the plurality of clamps includes a vertically extending main body and an outwardly folded inclined portion located at its top end. The outwardly folded inclined portion extends obliquely from the upper end of the main body in a direction away from the front of the main body, forming an angle greater than 90° between the two.

[0022] By adopting the above technical solution, the outward tilting part facilitates the position correction when the first board is lowered, which helps to ensure that the upper and lower boards are centered and fitted together.

[0023] Optionally, a push-pull clamp is provided on the outer side of the lower crossbeam, and a stop block is provided on the outer side of the upper crossbeam corresponding to the position of the push-pull clamp. The upper and lower crossbeams are provided with fixing members for fixing the push-pull clamp and the stop block.

[0024] By adopting the above technical solution, when the span of the plate is too long, it is necessary to avoid deformation in the middle when the cross frame is under load. At this time, the positions of the push-pull clamp and the stop block are adjusted simultaneously so that they are placed in the middle position of the cross frame under load. Then, the push-pull clamp is activated so that the extension end of the push-pull clamp is pressed against the bottom surface of the stop block to play an auxiliary support role.

[0025] Optionally, a limit baffle is provided at one end of the cross frame, and the cross frame is provided with a lifting component for driving the limit baffle to rise and fall.

[0026] By adopting the above technical solution, the lifting component drives the limit baffle to rise. When the board is conveyed on the conveying roller and comes into contact with one side of the limit baffle, the third driving component is turned off. At this time, the conveying roller stops conveying and the board loading operation is completed, which helps to improve the convenience of board flipping and bonding.

[0027] In summary, this application includes the following beneficial technical effect:

[0028] This application employs a clever spatial layout, staggering the main boom, tilting arm, and conveyor rollers. During continuous operation, the first sheet is lifted by a lifting assembly, leaving space below for the second sheet to be conveyed and positioned. Subsequently, the first sheet is tilted 180 degrees and lowered for bonding directly in the space above it. This in-situ and multi-level operation mode avoids the lateral area required for large-span tilting operations of traditional equipment, significantly saving space in the workshop.

[0040] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0041] See Figures 1-2A type of in-situ flipping machine includes a base frame 1, with two layers of horizontal frames 2 fixedly connected to the top surface of the base frame 1. In this embodiment, two layers of horizontal frames 2 are fixedly installed. Conveyor rollers 3 are fixedly installed on the top surfaces of the two layers of horizontal frames 2, and multiple conveyor rollers 3 are provided, with adjacent conveyor rollers 3 spaced apart. A vertical frame assembly 4 is fixedly connected to one side of the base frame 1, and a main beam 5 is installed on the side of the vertical frame assembly 4 facing the horizontal frames 2. Main arms 6 are fixedly connected to the side of the main beam 5 facing the horizontal frames 2, and multiple main arms 6 are provided, arranged in a linear array along the length of the main beam 5. A flipping arm 7 is installed on one end of each main arm 6 facing the horizontal frames 2, and the position of the flipping arm 7 is staggered from the position of the conveyor rollers 3, which facilitates the insertion of the flipping arm 7 into the spacing between adjacent flipping arms 7. In addition, a flipping assembly is installed on the main beam 5, which is used to simultaneously drive multiple flipping arms 7 to flip. A suction cup assembly 8 is fixedly installed on the support surface of the flipping arm 7, and the suction cup assembly 8 is connected to a negative pressure pump through a hose. The support frame 4 is also equipped with a lifting assembly, which is used to lift the main beam 5.

[0042] The specifications of the board 34 are diverse. When bonding small-sized boards 34, the two boards 34 are first conveyed to the upper and lower cross frames 2 by the conveying roller 3. Since the board 34 is small, the board 34 in the lower cross frame 2 can be taken out manually. Then the lower board 34 is flipped manually and finally bonded to the board 34 in the upper cross frame 2 to complete the bonding operation of the board 34.

[0043] When bonding larger sheet materials 34, the main arm 6 and the tilting arm 7 are first lowered and positioned below the conveyor roller 3 of the upper crossbeam 2 using a lifting assembly. After the first sheet material 34 is conveyed onto the upper crossbeam 2 via the conveyor roller 3, the main arm 6 and the tilting arm 7 are then raised by the lifting assembly. At this point, the tilting arm 7 lifts the first sheet material 34 and uses the suction cup assembly 8 to apply negative pressure to fix it. Next, the second sheet material 34 is conveyed onto the upper crossbeam 2 via the conveyor roller 3. Once the second sheet material 34 is in place, the tilting assembly is activated. The tilting assembly simultaneously drives multiple tilting arms 7 to tilt, and the multiple tilting arms 7, together with the suction cup assembly 8, tilt the first sheet material 34 180 degrees. Finally, the lifting assembly lowers the first sheet material 34 until the two sheets 34 are bonded together. This process is repeated to complete the continuous bonding operation of the sheet materials 34.

[0044] For details, see Figure 1 , Figure 3 and Figure 4The lifting assembly includes a main shaft 9, which is rotatably connected to the top surface of the upright assembly 4. A chain gear transmission assembly 10 is connected to the side wall of the main shaft 9, each chain gear transmission assembly 10 mainly consisting of a chain belt and two sprockets. A main beam 5 is guided and lifted on the side of the upright assembly 4 facing the crossbeam 2, and the main beam 5 is fixedly connected to one side of the chain belt of the chain gear transmission assembly 10. A counterweight 11 is guided and lifted on the side of the upright assembly 4 away from the crossbeam 2, and the counterweight 11 is fixedly connected to the other side of the chain belt of the chain gear transmission assembly 10. In addition, the upright assembly 4 is also equipped with a first driving member 12, which drives the main shaft 9 to rotate.

[0045] When the first drive unit 12 is started, the first drive unit 12 drives the main shaft 9 to rotate. The main shaft 9 simultaneously drives the chain gear transmission group 10 to drive. Under the gravity balance of the counterweight 11, the chain gear transmission group 10 drives the main beam 5 to rise and fall. The main beam 5 simultaneously drives multiple main arms 6 and tilting arms 7 to rise and fall. The tilting arms 7 then drive the plate 34 to rise and fall through the suction cup group 8. In the above process, the counterweight 11 helps to avoid the chain gear transmission group 10 from skipping teeth.

[0046] For details, see Figure 4 The tilting assembly includes a drive shaft 13, which is rotatably mounted on the side of the main beam 5 facing the crossbeam 2, and the drive shaft 13 rotates simultaneously and passes through multiple main arms 6. A synchronous pulley 14 is drively connected to the inner side of the main arm 6 and the middle side of the tilting arm 7. A second drive component 15 is also mounted on the main beam 5, which drives the drive shaft 13 to rotate.

[0047] When the second drive unit 15 is started, the second drive unit 15 drives the transmission shaft 13 to rotate. The transmission shaft 13 drives the corresponding flipping arm 7 to flip through the synchronous belt pulley 14. At this time, multiple flipping arms 7 rotate synchronously, and multiple flipping arms 7 drive the plate 34 to flip outward 180 degrees through the suction cup group 8.

[0048] It is worth noting that when flipping the easily flowable adhesive sheet 34, the adhesive can easily be flung out of the equipment at the moment of flipping. To reduce the occurrence of this situation, please refer to [link / reference needed]. Figure 5 The top surface of the main beam 5 is detachably equipped with an arc plate 16. Multiple suction nozzles 17 are fixedly connected to the inner side of the arc plate 16. The multiple suction nozzles 17 are also connected to the negative pressure pump through hoses, and the suction port of the suction nozzle 17 is outwardly flared.

[0049] As the tilting arm 7 tilts, the negative pressure pump starts, and multiple suction nozzles 17 simultaneously adsorb the adhesive surface of the board 34, thereby counteracting the centrifugal force when the board 34 tilts instantly, reducing adhesive splashing outside the equipment, and the outwardly expanding suction nozzles 17 help to increase the suction range and improve applicability.

[0050] See Figure 6 and Figure 8 The inner side of the cross frame 2 is equipped with a vertical bearing 18, and a horizontal shaft 19 is rotatably mounted inside the vertical bearing 18. The horizontal shaft 19 is connected to each conveyor roller 3 via an elastic flat belt 20. It is worth noting that the elastic flat belt 20 is a Möbius strip structure, which is a one-sided, boundaryless continuous curved surface formed by twisting one end of a flat elastic belt 180° and then bonding it end-to-end. Simultaneously, the cross frame 2 is also equipped with a third drive component 35, which drives the horizontal shaft 19 to rotate.

[0051] When the third drive unit 35 is activated, it drives the horizontal shaft 19 to rotate. The horizontal shaft 19 then drives the corresponding conveyor rollers 3 to rotate via multiple elastic flat belts 20. Compared to gear and chain drive, using the elastic flat belts 20 not only reduces mechanical noise from the transmission mechanism but also allows for independent adjustment of the distance between adjacent conveyor rollers 3, facilitating the lowering of the tilting arm 7 between adjacent conveyor rollers 3 and improving work efficiency.

[0052] See Figure 9 To facilitate adjustment of the tension of the elastic flat belt 20, the cross frame 2 is also equipped with an adjustment assembly. The adjustment assembly includes a screw 21, and a vertical hole 22 is provided through the side wall of the cross frame 2. The slider 36 is slidably connected in the vertical hole 22. The screw 21 is rotatably connected to the side of the cross frame 2 away from the conveyor roller 3 via a support, and the screw 21 is threadedly connected to the slider 36.

[0053] It is worth mentioning that the screw 21 is positioned offset from the main arm 6 and the tilting arm 7, which helps to avoid interference and collision between the main arm 6 and the tilting arm 7 and the screw 21 when they sink. When the screw 21 is rotated, under the rotation limit action of the vertical hole 22, the screw 21 drives the slider 36 to rise and fall, and the slider 36 drives the vertical bearing 18 to rise and fall, which in turn tightens or loosens the tension of the elastic flat belt 20.

[0054] See Figure 6 and Figure 10 To facilitate the centering and limiting of the plate 34 on the conveyor roller 3, a support frame 23 is fixedly connected to the inner side of the cross frame 2. A clamping crossbar 24 is symmetrically slidably connected to the top surface of the support frame 23. A clamping plate 25 is fixedly connected to the top surface of the clamping crossbar 24. There are multiple clamping plates 25, which are arranged in a straight array along the length of the clamping crossbar 24.

[0055] In addition, the crossbeam 2 is also equipped with a drive assembly, which is used to drive the two symmetrical clamping crossbars 24 to move towards each other. The drive assembly includes a cylinder 26 and a gear and rack transmission assembly 27. The cylinder 26 and the gear and rack transmission assembly 27 are both fixedly connected to the top surface of the support frame 23, and the gear and rack transmission assembly 27 is symmetrically installed on both sides of the cylinder 26. The telescopic end of the cylinder 26 is fixedly connected to one of the clamping crossbars 24, and both ends of each gear and rack transmission assembly 27 are fixedly connected to the two symmetrical clamping crossbars 24.

[0056] When cylinder 26 is started, the extension end of cylinder 26 drives one of the clamping bars 24 to move. At the same time, one of the clamping bars 24 drives the other clamping bar 24 to move in the opposite direction through the gear and rack transmission group 27.

[0057] It is worth noting that each of the multiple clamps 25 includes a vertically extending main body 28 and an outwardly folded inclined portion 29 located at its top. The outwardly folded inclined portion 29 extends obliquely from the upper end of the main body 28 in a direction away from the front of the main body 28, and the two form an angle greater than 90°.

[0058] When the first board 34 descends, the outward tilting part 29 corrects the position of the first board 34 as it descends, ensuring that the upper and lower boards 34 are centered and fitted together.

[0059] See Figure 2 and Figure 7 A push-pull clamp 30 is installed on the outer side of the lower crossbeam 2, and a stop block 31 is installed on the outer side of the upper crossbeam 2. The push-pull clamp 30 and the stop block 31 are directly opposite each other. The upper and lower crossbeams 2 are equipped with fasteners. In this embodiment, the fasteners are bolts. The push-pull clamp 30 and the stop block 31 are detachably connected to the crossbeam 2 by bolts.

[0060] When the span of the plate 34 is too long, it is necessary to prevent deformation in the middle of the cross frame 2 when it is under load. At this time, the positions of the push-pull clamp 30 and the stop block 31 are adjusted simultaneously so that they are placed in the middle position of the cross frame 2 under load, and the positions are fixed by bolts. Then, the push-pull clamp 30 is activated so that the telescopic end of the push-pull clamp 30 is pressed against the bottom surface of the stop block 31, thereby playing an auxiliary support role.

[0061] See Figure 2 A limit baffle 32 is installed at one end of the cross frame 2. The cross frame 2 is also equipped with a lifting component 33, which is used to drive the limit baffle 32 to rise and fall. In this embodiment, the lifting component 33 is a cylinder 26.

[0062] The limiting baffle 32 is used to cooperate with the clamping plate 25 to align and bond the two plates 34. When the lifting component 33 is started, the lifting component 33 drives the limiting baffle 32 to rise. When the plate 34 is conveyed on the conveying roller 3 until it comes into contact with one side of the limiting baffle 32, the transmission of the conveying roller 3 is stopped, so that the plate 34 is stably placed on the conveying roller 3.

[0063] It should be noted that the first drive component 12, the second drive component 15, and the third drive component 35 are geared motors, and their transmission methods are direct drive or belt drive.

[0064] The working principle of an in-situ flipping machine:

[0065] The specifications of the board 34 are diverse. When bonding small-sized boards 34, the two boards 34 are first conveyed to the upper and lower cross frames 2 by the conveying roller 3. Since the board 34 is small, the board 34 in the lower cross frame 2 can be taken out manually. Then the lower board 34 is flipped manually and finally bonded to the board 34 in the upper cross frame 2 to complete the bonding operation of the board 34.

[0066] When bonding larger sheet materials 34, the first drive unit 12 is activated first. The first drive unit 12 drives the main shaft 9 to rotate. The main shaft 9 simultaneously drives the chain gear transmission group 10. Under the gravity balance of the counterweight 11, the chain gear transmission group 10 drives the main beam 5 to descend. The main beam 5 simultaneously drives multiple main arms 6 and tilting arms 7 to descend. At this time, the main arms 6 and tilting arms 7 sink below the conveyor roller 3.

[0067] Based on the specifications of the actual processed sheet metal 34, the spacing between the relative clamping plates 25 is adjusted. To do this, cylinder 26 is first activated. The extension and retraction end of cylinder 26 moves one of the clamping crossbars 24. Simultaneously, one clamping crossbar 24, through a gear and rack transmission assembly 27, drives another clamping crossbar 24 to move towards it. At this point, the spacing between the opposing clamping plates 25 is the same as the width of the sheet metal 34. Next, lifting component 33 is activated, causing the limiting baffle 32 to rise. Then, the first sheet metal 34 is conveyed onto the conveyor roller 3 on the upper crossbar 2 until the sheet metal 34 abuts against one side of the limiting baffle 32.

[0068] After the first plate 34 is positioned correctly, the first drive unit 12 is reset and activated, which causes the flipping arm 7 to adhere to and lift the first plate 34 via the suction cup assembly 8. Next, the second plate 34 is conveyed onto the conveyor roller 3 of the upper crossbeam 2, and is also positioned by the clamping plate 25 and the limiting baffle 32. After the second plate 34 is in place, the second drive unit 15 is activated, which drives the transmission shaft 13 to rotate. The transmission shaft 13 drives the corresponding flipping arm 7 to rotate via the synchronous pulley 14. At this time, multiple flipping arms 7 rotate synchronously, and multiple flipping arms 7 drive the first plate 34 to rotate outward by 180 degrees via the suction cup assembly 8.

[0069] Finally, the first drive component 12 lowers the flipping arm 7, and under the action of the outward tilting part 29, the position of the first plate 34 is corrected when it is lowered, so that the upper and lower plates 34 are centered and attached.

[0070] In summary, through clever spatial arrangement, the main arm 6, the tilting arm 7, and the conveyor roller 3 are staggered. During continuous operation, the lifting assembly raises the first plate 34, leaving space below for the second plate 34 to be conveyed into position. Subsequently, the first plate 34 is tilted 180 degrees and lowered for bonding directly in the space above it. This in-situ and multi-level operation mode avoids the lateral area required for large-span tilting in traditional equipment, greatly saving workshop space.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
