Description

Technical Field

[0001] The present invention belongs to the technical field of automatic workpiece flipping, and particularly relates to a conveying and flipping mechanism and an implementation method thereof. Background Art

[0002] As Figure 6 shown, during the production process, the workpiece needs to be flipped (90 degrees or 180 degrees), Figure 6 from left to right are the incoming material state, the 90-degree flipping state, and the 180-degree flipping state, and then conveyed to the next process. The traditional flipping method is to use a motor or a rotary cylinder on the workstation to drive the fixture or tooling to flip the workpiece. The main problems of this traditional method are that the flipping mechanism is complex, the cost is high, and the speed is slow. If continuous production is carried out on the production line, the conveying line needs to be separately cut, and the flipping mechanism is arranged in the middle of the conveying line, resulting in a complex overall structure and high cost. Summary of the Invention

[0003] The purpose of the present invention is to provide a conveying and flipping mechanism to solve the problems raised in the above background art. A conveying and flipping mechanism provided by the present invention has the characteristics of simple structure, low cost, and high efficiency.

[0004] Another purpose of the present invention is to provide an implementation method of a conveying and flipping mechanism.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A conveying and flipping mechanism includes a conveyor belt, an air blowing component is connected inside the middle position of the conveyor belt, a position detection sensor is connected at a position corresponding to the air blowing component on one side of the conveyor belt, and the conveyor belt and the position detection sensor are respectively signal-connected to a controller.

[0006] Further in the present invention, the conveyor belt is a double-row conveyor belt.

[0007] Further in the present invention, the air blowing component includes an air blowing block and air blowing holes. Among them, the air blowing block is connected to the conveyor belt, and several air blowing holes are provided on the air blowing block.

[0008] Further in the present invention, an air vent speed regulating valve is connected to the air inlet end of the air blowing block.

[0009] Further in the present invention, a flipping blocking rod is connected at a position corresponding to the air blowing component on the other side of the conveyor belt.

[0010] Further in the present invention, guiding components are respectively connected to both sides of the conveyor belt.

[0011] Further in the present invention, the guiding component includes a mounting seat and a guiding rod. Among them, the mounting seat is installed on the side of the conveyor belt, a support column is connected above the mounting seat, a clamping seat is provided on the support column, and the guiding rod is installed on the clamping seat.

[0012] In the present invention, further, the clamping seat is slidably connected to the support column through an adjustment shaft, and an adjustment screw is engaged above the support column, and the end of the adjustment screw abuts against the adjustment shaft.

[0013] In the present invention, further, the implementation method of the conveying and flipping mechanism includes the following steps:

[0014] (1). The L-shaped workpiece transferred from the previous process is conveyed forward through the conveyor belt;

[0015] (2). When the L-shaped workpiece reaches the position of the in-place detection sensor, the blowing assembly is triggered to blow air;

[0016] (3). The air blowing holes are ventilated, and the air blowing force F gives an upward force to the L-shaped workpiece, so that the front bottom of the L-shaped workpiece is separated from the conveyor belt. However, under the action of the forward frictional force f of the conveyor belt, the right bottom of the L-shaped workpiece continues to move forward with the conveyor belt. At this time, the L-shaped workpiece is flipped under the action of the torque M. When the resultant torque ΣM of the L-shaped workpiece caused by the applied air blowing force F is less than 0, the L-shaped workpiece will flip clockwise;

[0017] (4). If only a 90-degree flip of the L-shaped workpiece is required, the flipping blocking rod is installed above the conveyor belt, and the L-shaped workpiece is blocked by the flipping blocking rod to prevent it from flipping more than 90 degrees;

[0018] (5). If a 180-degree flip is required, the flipping blocking rod does not need to be installed, and the ventilation speed regulating valve is adjusted to adjust the air flow speed and extend the air blowing time, increasing the resultant torque ΣM of the L-shaped workpiece to achieve a 180-degree flip;

[0019] (6). After the L-shaped workpiece is flipped in place, the blowing assembly stops blowing air, and the L-shaped workpiece continues to be conveyed forward in the flipped posture.

[0020] In the present invention, further, for the implementation method of the conveying and flipping mechanism, the conveyor belt is a double-row conveyor belt; the blowing assembly includes a blowing block and air blowing holes. Among them, the blowing block is connected to the conveyor belt, and several air blowing holes are provided on the blowing block; a ventilation speed regulating valve is connected to the air inlet end of the blowing block; a flipping blocking rod is connected to the position corresponding to the blowing assembly on the other side of the conveyor belt; guiding assemblies are respectively connected to both sides of the conveyor belt; the guiding assembly includes a mounting seat and a guiding rod. Among them, the mounting seat is installed on the side of the conveyor belt, a support column is connected above the mounting seat, a clamping seat is provided on the support column, and the guiding rod is installed on the clamping seat; the clamping seat is slidably connected to the support column through an adjustment shaft, and an adjustment screw is engaged above the support column, and the end of the adjustment screw abuts against the adjustment shaft.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention does not require truncating the conveyor line, nor does it need to use a rotating tooling method to flip the workpiece. Instead, it directly uses a pneumatic method to flip the workpiece at the middle position of the conveyor line, with a simple structure, low cost, and high efficiency.

[0023] 2. The present invention applies an upward air blowing force F to the workpiece through blowing, so that a clockwise torque M is generated under the action of the air blowing force F to drive the workpiece to flip. The structure is simple, the cost is low, and only by adjusting the magnitude of the intake air volume to find the balance point of the external force for flipping the workpiece, the flipping of the workpiece can be easily achieved, with simple and convenient control and convenient installation.

[0024] 3. When the present invention needs to flip the workpiece by 90 degrees, it can be achieved by means of the cooperation of the flipping blocking rod, and the switching between flipping the workpiece by 90 degrees and 180 degrees is simple and convenient.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figures 1 - 5 , the present invention provides the following technical solution: A conveying and flipping mechanism includes a conveyor belt 1. An air blowing assembly 2 is connected inside the middle position of the conveyor belt 1. A position detection sensor 3 is connected to the position corresponding to the air blowing assembly 2 on one side of the conveyor belt 1. The position detection sensor 3 is of the CX-411A-C05 type sold by Panasonic. The conveyor belt 1 and the position detection sensor 3 are respectively connected to the controller in a signal connection.

[0036] Further, the conveyor belt 1 is a double-row conveyor belt, and the double-row conveyor belt is of the GVTWAU-50-800-25-TA220-SCM-15-S-C type sold by MISUMI.

[0037] By adopting the above technical solution, the L-shaped workpiece 5 is conveyed by the double-row conveyor belt.

[0038] Further, the air blowing assembly 2 includes an air blowing block 21 and air blowing holes 22. Among them, the air blowing block 21 is connected to the conveyor belt 1. A plurality of air blowing holes 22 are provided on the air blowing block 21. An air vent speed regulating valve 23 is connected to the air inlet end of the air blowing block 21. The air vent speed regulating valve 23 is of the PSL6M5A type sold by AirTAC. The air inlet end of the air vent speed regulating valve 23 is connected to the air source through a connecting pipe, and an electromagnetic valve is connected to the connecting pipe. The electromagnetic valve is connected to the controller in a signal connection.

[0039] By adopting the above technical solution, the L-shaped workpiece 5 is blown through the air blowing holes 22, so as to apply an air blowing force F to the L-shaped workpiece 5 to promote the flipping of the L-shaped workpiece 5; the air vent speed regulating valve 23 is used to regulate the air flow speed.

[0040] Further, a flipping blocking rod 4 is connected to the position corresponding to the air blowing assembly 2 on the other side of the conveyor belt 1.

[0041] By adopting the above technical solution, when it is necessary to flip the L-shaped workpiece 5 by 90 degrees, it is necessary to limit the L-shaped workpiece 5 through the flipping blocking rod 4 so that it stops after flipping 90 degrees.

[0042] The controller is of the FX3U-48M type sold by Mitsubishi Electric.

[0043] Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 lies in that: Further, guiding components 6 are respectively connected to both sides of the conveyor belt 1. The guiding component 6 includes a mounting seat 61 and a guiding rod 62. Among them, the mounting seat 61 is mounted on the side of the conveyor belt 1. A support column 63 is connected above the mounting seat 61. A clamping seat 65 is provided on the support column 63. The guiding rod 62 is mounted on the clamping seat 65. The clamping seat 65 is slidably connected to the support column 63 through an adjusting shaft 64. An adjusting screw 66 is engaged above the support column 63. The end of the adjusting screw 66 abuts against the adjusting shaft 64.

[0045] By adopting the above technical solution, the movement of the L-shaped workpiece 5 can be guided by the guiding rod 62; at the same time, the distance between the guiding components 6 on both sides can be adjusted, so as to be applicable to workpieces of different sizes.

[0046] Further, the implementation method of the conveying and flipping mechanism of the present invention includes the following steps:

[0047] (1). The L-shaped workpiece 5 transferred from the previous process is conveyed forward by the conveyor belt 1;

[0048] (2). When the L-shaped workpiece 5 reaches the position of the in-place detection sensor 3, the blowing component 2 is triggered to blow air;

[0049] (3). The air blowing holes 22 are ventilated, and the air blowing force F gives an upward force to the L-shaped workpiece 5, so that the front bottom of the L-shaped workpiece 5 is separated from the conveyor belt 1. However, under the action of the forward frictional force f of the conveyor belt 1, the right bottom of the L-shaped workpiece 5 continues to move forward with the conveyor belt 1. At this time, the L-shaped workpiece 5 rotates under the action of the moment M. As Figure 5 shown, when the resultant moment ΣM of the L-shaped workpiece 5 caused by the applied air blowing force F is less than 0, the L-shaped workpiece 5 will rotate clockwise;

[0050] (4). If only a 90-degree rotation of the L-shaped workpiece 5 is required, the rotation blocking rod 4 is installed above the conveyor belt 1, and the L-shaped workpiece 5 is blocked by the rotation blocking rod 4 to prevent it from rotating more than 90 degrees;

[0051] (5). If a 180-degree rotation is required, the rotation blocking rod 4 does not need to be installed, and the air flow speed and the air blowing time are adjusted by adjusting the ventilation speed control valve 23 to increase the resultant moment ΣM of the L-shaped workpiece 5 to achieve a 180-degree rotation;

[0052] (6). After the L-shaped workpiece 5 rotates in place, the blowing component 2 stops blowing air, and the L-shaped workpiece 5 continues to be conveyed forward in the rotated posture.

[0053] The formula used for the force synthesis of the L-shaped workpiece 5 is: ΣM = M G +M FB -M F ; ΣFx = -f - FBx = 0; ΣFy = F N +F - G - F By = 0. Wherein, f is the frictional force, F is the air blowing force, F N is the supporting force, G is the gravitational force, F B is the restraint force of the flipping blocking rod.

[0054] In summary, the present invention does not require truncating the conveying line, nor does it need to use a rotating tooling method to flip the workpiece. Instead, it directly uses a pneumatic method to flip the workpiece at the middle position of the conveying line, with a simple structure, low cost, and high efficiency. The present invention applies an upward air blowing force F to the workpiece by blowing air, so that a clockwise moment M is generated under the action of the air blowing force F to drive the workpiece to flip. The structure is simple and the cost is low. Only by adjusting the amount of intake air to find the balance point of the external force for flipping the workpiece can the flipping of the workpiece be easily achieved, with simple and convenient control and convenient installation. When the present invention needs to flip the workpiece by 90 degrees, it can be achieved by means of the cooperation of the flipping blocking rod, and the switching between flipping the workpiece by 90 degrees and 180 degrees is simple and convenient. The present invention is provided with a guiding component, which can guide the movement of the workpiece through the guiding rod; at the same time, the distance between the two guiding components can also be adjusted to be applicable to workpieces of different sizes.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
