Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a conveyor belt turning device. Background Technology

[0002] In the production of sheet-like products (such as adapter sheets), to improve packaging and shipping efficiency, it is necessary to maintain the product's consistent state during transportation, i.e., keeping it facing either front or back. Existing patent CN221138835U discloses a flipping device capable of quickly flipping sheet-like products, thereby improving production efficiency. However, this device can only flip individual products, failing to meet the needs of existing production lines. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a conveyor belt flipping device, which realizes the automatic flipping of sheet products on the conveyor belt through two flipping mechanisms set on the side of the conveyor belt, thus solving the problem of inconsistent posture of sheet products on the conveyor belt.

[0004] To solve the above-mentioned technical problems, the present invention provides a conveyor belt flipping device, including a first conveyor belt and a second conveyor belt disposed below the discharge end of the first conveyor belt, and further including a first flipping mechanism and a second flipping mechanism disposed on one side of the second conveyor belt; when the workpiece is loaded, it is in an initial posture, and the first flipping mechanism is disposed below the discharge end of the first conveyor belt, so that after the workpiece falls from the discharge end of the first conveyor belt, it flips from the initial posture to a first posture and moves along the second conveyor belt in accordance with the first flipping mechanism; the second flipping mechanism is disposed on the movement path of the workpiece, and the workpiece can be transformed from the first posture to a final posture that is 180 degrees flipped from the initial posture under the action of the second flipping mechanism.

[0005] Furthermore, the first flipping mechanism includes a first guide plate disposed below the discharge end of the first conveyor belt. The first guide plate is installed on one side of the second conveyor belt along the running direction of the second conveyor belt, and the angle between the guide surface of the first guide plate and the surface of the second conveyor belt is greater than 90°, so that after the workpiece falls from the discharge end of the first conveyor belt, it flips from the initial posture to the first posture and can move on the second conveyor belt along the first guide plate.

[0006] Furthermore, the first flipping mechanism also includes a first limiting plate disposed on the other side of the second conveyor belt opposite to the first guide plate. The first limiting plate is perpendicular to the surface of the second conveyor belt, and the minimum distance between the first limiting plate and the first guide plate is less than the minimum width of the workpiece.

[0007] Furthermore, the second flipping mechanism includes a second guide plate and a second limiting plate. The second guide plate and the first guide plate are disposed on the same side of the second conveyor belt, and the guide surface of the second guide plate extends from the outside to the inside of the second conveyor belt along the running direction of the second conveyor belt to form an inclined surface, which enables the workpiece to move along the second guide plate and flip to the second posture after abutting the guide surface of the second guide plate. The second limiting plate and the second guide plate are disposed on opposite sides of the second conveyor belt, so that the workpiece moves along the second limiting plate and is adjusted to the final posture after abutting the second limiting plate.

[0008] Furthermore, the second conveyor belt includes two parallel, elongated conveyor belts, the distance between the two elongated conveyor belts being less than the minimum width of the workpiece.

[0009] Furthermore, an anti-drop baffle is provided between the gaps of the two slender conveyor belts. The upper surface of the anti-drop baffle is not higher than the surface of the second conveyor belt, which is used to prevent the workpiece from falling out of the gap when the workpiece is adjusted in the second flipping mechanism.

[0010] Furthermore, the width of the elongated conveyor belt is not less than the minimum distance between the first limiting plate and the first guide plate.

[0011] Furthermore, it also includes: a posture adjustment mechanism, which is disposed between the first flipping mechanism and the second flipping mechanism, so that a workpiece that has not flipped to the first posture after falling from the discharge end of the first conveyor belt can move along the posture adjustment mechanism and readjust to the first posture after abutting the posture adjustment mechanism.

[0012] Furthermore, the posture adjustment mechanism includes an adjustment block, which is opposite to the first guide plate, and the adjustment surface of the adjustment block extends from the first limiting plate to the first guide plate along the running direction of the second conveyor belt and forms an inclined surface, so that the workpiece that has not flipped to the first posture after falling from the discharge end of the first conveyor belt can move along the adjustment surface direction after abutting the adjustment block until it fits against the first guide plate.

[0013] Furthermore, it also includes: an emergency discharge mechanism disposed between the attitude adjustment mechanism and the second flipping mechanism, the emergency discharge mechanism including a driver and a side baffle, the side baffle and the first guide plate being disposed on the same side of the second conveyor belt, and the outer side of the side baffle being fixed to the driving end of the driver; when the driver is in a stopped state, the surface of the side baffle and the guiding surface of the first guide plate are located on the same plane; the fixed end of the driver is fixed outside the second conveyor belt, and the driving end is fixed to the outer side of the side baffle.

[0014] The conveyor belt flipping device of this utility model has at least the following beneficial effects: it can realize the automatic flipping of sheet products on the conveyor belt through two flipping mechanisms set on the side of the conveyor belt, solving the problem of inconsistent posture of sheet products on the conveyor belt; in the event of workpiece accumulation between the posture adjustment mechanism and the second flipping mechanism, the workpieces accumulated on the second conveyor belt can be removed by the emergency material discharge mechanism; compared with the traditional method that requires independent equipment to flip the workstation, this application can save intermediate transfer time, and realize the flipping of the product at the same time as conveying it to the next workstation, thus improving efficiency.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Please refer to Figure 1The present invention exemplifies the structure of a conveyor belt flipping device. The illustrated conveyor belt flipping device includes a first conveyor belt 1, a second conveyor belt 2, a first flipping mechanism 3, and a second flipping mechanism 4. The second conveyor belt 2 is positioned below the discharge end of the first conveyor belt 1, allowing sheet-like workpieces to fall onto the second conveyor belt 2 after being discharged from the first conveyor belt 1. In this embodiment, to reduce the space occupied by the device, the second conveyor belt 2 and the first conveyor belt 1 are arranged in an L-shape. It should be noted that in this embodiment, the state of the sheet-like workpiece when it is being fed (i.e., its position above the first conveyor belt 1) is defined as the initial posture. The purpose of this device is to flip the sheet-like workpiece in the initial posture to a final posture that is 180 degrees flipped from the initial posture. In this embodiment, the flipping process requires two posture adjustments. The first adjustment occurs when the sheet-like workpiece falls from the discharge end of the first conveyor belt 1 and enters the first flipping mechanism 3. This first flipping mechanism 3 is located on one side of the second conveyor belt 2, below the discharge end of the first conveyor belt 1. This allows the sheet-like workpiece to form a first posture that conforms to the first flipping mechanism 3 after falling, and to move along the second conveyor belt 2 in this first posture. The second posture adjustment occurs in the second flipping mechanism 4, which is positioned along the workpiece's movement path. This mechanism further adjusts the workpiece from its first posture to a final posture that is 180 degrees flipped from its initial posture. By using these two flipping mechanisms, the sheet-like workpiece can automatically adjust its posture on the conveyor belt, meeting the requirements for automated production and packaging of sheet-like workpieces, thus improving production efficiency.

[0029] Please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of another embodiment of the conveyor belt flipping device of this utility model. Figure 3 for Figure 2 A magnified view of a portion of point A in the middle, and Figure 3 The diagram below shows the structure of the first flipping mechanism 3 in this device. The first flipping mechanism 3 includes a first guide plate 31 and a first limiting plate 32. The first guide plate 31 is installed on one side of the second conveyor belt 2 along its running direction. The guiding surface of the first guide plate 31 is approximately a plane, which forms a certain angle with the surface of the second conveyor belt 2. This allows the workpiece to flip by no more than 90° when it falls from the discharge end of the first conveyor belt 1 and adheres to the guiding surface of the first guide plate 31, i.e., flipping from the initial posture to the first posture. Since one side (front or back) of the workpiece adheres to the first guide plate 31, while the other side still falls on the second conveyor belt 2, the workpiece can move along the running direction of the second conveyor belt 2 in the first posture of adhering to the first guide plate 31.

[0030] In addition, to prevent some workpieces from colliding with the first guide plate 31 or the second conveyor belt 2 and bouncing after falling from the discharge end of the first conveyor belt 1, causing them to fall off the conveyor belt 2, a first limiting plate 32 is also provided in this embodiment. The first limiting plate 32 is arranged opposite to the first guide plate 31, and the distance between the two decreases from top to bottom, so that the two form a certain angle. At the same time, the minimum distance between the two is less than the minimum width of the workpiece, so that the workpiece will definitely be in contact with the first guide plate 31 or the second conveyor belt 2 after falling from the discharge end of the first conveyor belt 1.

[0031] Figure 5 for Figure 2 A magnified view of section C, which is also a schematic diagram of the attitude adjustment mechanism. Please refer to... Figure 2 and Figure 5 Because of the arrangement of the first limiting plate 32 and the first guide plate 31, although it can prevent the workpiece from colliding with the first guide plate 31 or the second conveyor belt 2 and bouncing after falling from the discharge end of the first conveyor belt 1, causing it to fall off the conveyor belt 2, such an arrangement cannot ensure that all workpieces are adjusted to the first posture before entering the second flipping mechanism 4. Therefore, this embodiment also includes a posture adjustment mechanism. The posture adjustment mechanism is arranged between the first flipping mechanism 3 and the second flipping mechanism 4, so that workpieces that have not flipped to the first posture after falling from the discharge end of the first conveyor belt 1 (i.e., workpieces that are attached to the first limiting plate 32) can move along the posture adjustment mechanism and readjust to the first posture after abutting against the posture adjustment mechanism.

[0032] Specifically, the attitude adjustment mechanism includes an adjustment block 6. The adjustment block 6 is disposed opposite to the first guide plate 31. The adjustment block 6 operates through its adjustment surface, which is an inclined surface extending from the first limiting plate 32 to the first guide plate 31 along the running direction of the second conveyor belt 2. This allows the workpiece, which is attached to the first limiting plate 32, to re-attach to the first guide plate 31 along the adjustment surface when it reaches the adjustment block 6, thus completing the attitude adjustment of the workpiece that has not been flipped to the first attitude.

[0033] Figure 4 for Figure 2 Please refer to the enlarged view at point B, which is also a structural schematic diagram of the second flipping mechanism 4. Figure 2 and Figure 4The second flipping mechanism 4 includes a second guide plate 41 and a second limiting plate 42. The second guide plate 41 is located on the same side of the second conveyor belt 2 as the first guide plate 31, and its structure and function are similar to those of the adjusting block 6. The second guide plate 41 operates through its guiding surface, which is an inclined surface extending inward from the outer side of the second conveyor belt 2 (also the side of the first guide plate 41) to the inner side (i.e., the side of the second limiting plate 42) along the running direction of the second conveyor belt 2. Similar to the adjusting block 6, when the workpiece moves to the second guide plate 41 in its first posture, the workpiece abuts against the guiding surface of the second guide plate 41, causing the workpiece to move along the direction of the guiding surface, thereby flipping the workpiece to a second posture. The second limiting plate 42 is arranged opposite to the second guide plate 41, and the second limiting plate 42 and the second guide plate 41 are arranged on opposite sides of the second conveyor belt 2. The working surface of the second limiting plate 42 is parallel to the running direction of the second conveyor belt 2, so that after the workpiece comes into contact with the second limiting plate 42, it can move along its working surface and adjust to the final posture.

[0034] Please refer to Figure 1-7 Since the sheet-like workpiece in this embodiment has a protruding structure in the middle, the second conveyor belt 2 is configured as two parallel, slender conveyor belts to accommodate the workpiece. This allows the protruding structure to be placed in the gap between the two slender conveyor belts when the workpiece is on the second conveyor belt 2, thereby improving the stability of the workpiece on the second conveyor belt 2. At the same time, the distance between the two slender conveyor belts is less than the minimum width of the workpiece, thus preventing the workpiece from falling out of the gap.

[0035] For further details, please refer to Figure 4 An anti-drop baffle 5 is provided in the gap between the two slender conveyor belts. The upper surface of the anti-drop baffle 5 is not higher than the surface of the second conveyor belt 2, so that the workpiece can fall from the gap between the two slender conveyor belts when the workpiece is adjusted in the second flipping mechanism 4.

[0036] It is worth mentioning that the width of each of the above-mentioned slender conveyor belts should not be less than the minimum distance between the first limiting plate 32 and the first guide plate 31, so as to ensure that when the workpiece is in the first flipping mechanism 3, its front and back sides can only be attached to the first limiting plate 32 or the first guide plate 31, while one side can only be on the second conveyor belt 2.

[0037] Figure 7 for Figure 6 The enlarged view at point D, which is also a structural schematic diagram of the emergency material discharge mechanism 7 in this device, is shown in the attached image. Figure 7 and Figure 6In this embodiment, an emergency discharge mechanism 7 is also included. This emergency discharge mechanism 7 is disposed between the attitude adjustment mechanism (in this embodiment, the attitude adjustment mechanism is the adjustment block 6) and the second tilting mechanism 4, that is, the emergency discharge mechanism 7 is located in the path of the workpiece moving from the adjustment block 6 to the second tilting mechanism 4. When workpieces accumulate at the next workstation at the end of the second conveyor belt 2, the emergency discharge mechanism 7 can be opened to allow the workpieces to fall off the second conveyor belt 2, thereby ensuring the smooth operation of the production line. Specifically, the emergency discharge mechanism 7 includes a driver 71 and a side baffle 72. The side baffle 72 serves as the "door" of the emergency discharge mechanism 7. This side baffle 72 and the first guide plate 31 are located on the same side of the second conveyor belt 2, and the outer side of the side baffle 72 (the side facing away from the second conveyor belt 2) is fixed to the driving end of the driver 71. When the driver 71 is in a stopped state (i.e., not driven), the inner surface of the side baffle 72 and the guiding surface of the first guide plate 31 are on the same plane. This ensures that when the driver 71 is stopped, the workpiece can maintain its first posture after moving along the first guide plate 31 to the side baffle 72. In this embodiment, the driver 71 can be a motor or other driving device. The fixed end of the driver 71 is fixed outside the second conveyor belt 2, and its driving end is fixed to the outer side of the side baffle 72. When workpieces accumulate at the next workstation at the end of the second conveyor belt 2, the driver 71 can be activated, causing the side baffle 72 to open a discharge space relative to the second conveyor belt 2 under the drive of the driving end, allowing the workpiece to fall from there.

[0038] In summary, the working principle of the conveyor belt flipping device of this utility model is as follows: After the workpiece is loaded onto the first conveyor belt 1, it is in the initial posture. As the first conveyor belt 1 moves, the workpiece falls from the discharge end of the first conveyor belt 1 to the first guide plate 31 and flips to the first posture. At this time, some workpieces that have not completed the first posture flipping will stick to the first limiting plate 32. As the second conveyor belt 2 moves, when this part of the workpiece moves to the adjusting block 6, it can readjust its posture to the first posture along the adjusting block 6. After that, all workpieces continue to run with the second conveyor belt 2 in the first posture to the second guide plate 41, and move along the second guide plate 41 and flip to the second posture. Then, under the limiting action of the second limiting plate 42, the workpiece adjusts its posture to the final posture, completing a 180° flip relative to the initial posture.

[0039] Compared with the prior art, the conveyor belt flipping device of this utility model can automatically flip sheet-like products on the conveyor belt through two flipping mechanisms set on the side of the conveyor belt, thus solving the problem of inconsistent posture of sheet-like products on the conveyor belt. When workpieces accumulate at the next workstation at the end of the second conveyor belt 2, the emergency discharge mechanism 7 can be opened to allow the workpieces to fall off the second conveyor belt 2, thereby ensuring the smooth operation of the production line.
