It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0039] As Figures 1-9 shown, the present application discloses a sheet turning device 100 for turning a sheet-shaped material, which is a glass sheet in the embodiments of the present application. The sheet turning device 100 includes a sheet conveying mechanism, a frame 13, and a turning mechanism 14.

[0040] Among them, the sheet conveying mechanism includes a sheet input mechanism 11 and a sheet output mechanism 12; the frame 13 has two working modules with the same range, the sheet conveying mechanism is arranged on the frame 13, and the sheet input mechanism 11 and the sheet output mechanism 12 are respectively arranged in the two working modules; the turning mechanism 14 is arranged on the frame 13, and the turning mechanism 14 includes a turning drive motor 142 and a turning frame 141. The turning drive motor 142 is arranged at the end of the turning frame 141 and is in transmission connection with the turning frame 141. The turning frame 141 is arranged between the sheet input mechanism 11 and the sheet output mechanism 12, and the extending direction of the turning frame 141 is perpendicular to the conveying direction of the sheet by the sheet conveying mechanism. The turning frame 141 includes turning clamps 143 arranged on its outer peripheral side, and the turning clamps 143 can drive the sheet to be turned from the sheet input mechanism 11 to the sheet output mechanism 12 through the driving action of the turning drive motor 142 on the turning frame 141.

[0041] It can be understood that the flipping mechanism 14 is arranged between the plate input mechanism 11 and the plate output mechanism 12, and the flipping mechanism 14 plays a role of transfer and transmission between the two, so that after the plate enters from the plate input mechanism 11, it can be transferred to the plate output mechanism 12 by the flipping mechanism 14, and the plate is then transferred from the plate output mechanism 12 to the next process procedure for subsequent processing.

[0042] An example of "the extension direction of the turning frame is perpendicular to the conveying direction of the plate by the plate conveying mechanism": the plate conveying mechanism conveys the plate in the horizontal direction, and the turning frame 141 is arranged in the vertical direction, that is, the horizontal direction and the vertical direction are two different directions of the horizontal plane.

[0043] In the embodiment of the present application, the flip frame 141 is composed of an internal hollow square tube structure and a flip clamp 143 on the outer peripheral side of the square tube structure; in other embodiments, the flip frame 141 can be optimized based on the flipping requirements of plates of different specifications and thicknesses. For example, a solid columnar structure can be used to drive the flip clamp 143 to rotate, and the columnar structure needs to be connected to the output shaft of the flip drive motor 142, and then the flip clamp 143 is driven to rotate through the output shaft of the flip drive motor 142.

[0044] In the embodiments of the present application, Figure 9 As shown, a flip motor mounting frame 134 is also provided on the frame 13 for fixing and mounting the flip driving motor 142 .

[0045] Based on the above structure, the plate flipping device 100 of the present application adopts a linear layout, and the flipping mechanism 14 is located between the plate input mechanism 11 and the plate output mechanism 12, forming a clear "in-flip-out" process, making the operation more intuitive, easy for operators to understand and use, improving the flipping efficiency, and shortening the moving distance of the plate, reducing the risk of plate damage caused by long-distance movement; through the driving action of the flipping drive motor 142, the need for manual intervention is reduced, the labor intensity is reduced, and at the same time, direct manual contact with the flipping plate is avoided, thereby reducing the risk of accidents caused by improper manual operation. Finally, the plate flipping device 100 can be applied to plates of different sizes and materials, and has certain versatility and adaptability.

[0046] like Figure 2 and Figures 6-8 As shown, the flip clamp 143 is a pair of wedge-shaped plate structures arranged opposite to each other, and a spacer 1431 is provided on the opposite side of each wedge-shaped plate structure, and a shock-absorbing pad 1432 is provided on the inner wall surface of the connection between the two wedge-shaped plate structures and facing the plate.

[0047] In the embodiment of the present application, both the spacer 1431 and the shock-absorbing pad 1432 are made of soft materials.

[0048] In the embodiment of the present application, the flipping clamp 143 includes a first clamping plate 1433 and a second clamping plate 1434, and the plate is embedded in the first clamping plate 1433 and the second clamping plate 1434. Further, the extending direction of the first clamping plate 1433 and the rotation axis direction of the flipping frame 141 are perpendicular to each other on the horizontal plane, that is, the extending axis of the first clamping plate 1433 and the rotation axis of the flipping frame 141 are arranged in a staggered manner and do not intersect; the extension line of the second clamping plate 1434 can pass through the rotation axis of the flipping frame 141, so that the first clamping plate 1433 and the second clamping plate 1434 can present an intersecting state and form an included angle capable of receiving the plate, and the shock-absorbing pad 1432 is arranged in the included angle, and the spacer 1431 is arranged on the surface of the first clamping plate 1433 facing the second clamping plate 1434 and on the surface of the second clamping plate 1434 facing the first clamping plate 1433.

[0049] It should be noted that the rotation axis of the flipping frame 141 refers to the axis where the central axis of the rotation of the flipping frame 141 driving the flipping clamp 143 is located. When the flipping drive motor 142 is arranged at the end of the flipping frame 141, that is, when the output shaft of the flipping drive motor 142 and the rotation center of the flipping frame 141 are collinear, the rotation axis of the flipping frame 141 is the axis where the output shaft of the flipping drive motor 142 is located.

[0050] Specifically, in the embodiment of the present application, the sheet input mechanism 11 is located on the left side of the flipping mechanism 14, and the sheet output mechanism 12 is located on the right side of the flipping mechanism 14. Therefore, when the sheet is on the flipping mechanism 14, it is flipped in the clockwise direction (see Figure 6 ). Thus, when the flipping drive motor 142 drives the flipping frame 141 to rotate and the flipping clamp 143 rotates to the sheet input mechanism 11, the first clamping plate 1433 can present a horizontally extended state, and the second clamping plate 1434 is located above the first clamping plate 1433, and the two form a wedge-shaped opening with an upward opening, so that the sheet can be smoothly translated into the wedge-shaped opening; when the flipping drive motor 142 drives the flipping frame 141 to rotate and the flipping clamp 143 rotates to the sheet output mechanism 12, the first clamping plate 1433 still presents a horizontally extended state, but the second clamping plate 1434 is located below the first clamping plate 1433, and the two form a wedge-shaped opening with a downward opening, so that the sheet can naturally move out of the flipping clamp 143 by its own weight and fall onto the sheet output mechanism 12.

[0051] Therefore, the entire process of the flipping mechanism 14 driving the sheet to flip is as follows: when the sheet enters the flipping clamp 143 through the sheet input mechanism 11, one side surface of the sheet can contact the spacer 1431 on the first clamping plate 1433, minimizing the impact on the glass to the greatest extent; when the flipping drive motor 142 drives the flipping clamp 143 to rotate to the vertical state, the lower edge of the sheet will abut against the shock pad 1432 in the wedge-shaped opening due to the gravity; when the flipping drive motor 142 continues to drive the flipping clamp 143 to gradually move towards the sheet output mechanism 12, the other side surface of the sheet can contact the spacer 1431 on the second clamping plate 1434. Therefore, the sheet will not make direct contact with other parts of the flipping clamp 143 during the entire flipping process, and the wear on the sheet is reduced through the spacer 1431 and the shock pad 1432.

[0052] Thus, based on the above structure, the wedge-shaped plate structure has a larger contact area, thereby increasing the frictional force on the sheet. This not only reduces damage to the sheet but also prevents the sheet from slipping during flipping. Moreover, the wedge-shaped design can adapt to sheets of different thicknesses. Even if the sheet thickness changes, a good flipping "clamping" effect can be ensured. By setting the spacer 1431 and the shock pad 1432, the friction between the flipping clamp 143 and the sheet can be reduced, preventing the surface of the sheet from being scratched. In addition, the shock pad 1432 can absorb the impact force generated by the sheet on the flipping clamp 143 during flipping, reducing damage to the sheet and the flipping clamp 143, and improving the stability of the flipping process.

[0053] It can be understood that the above-mentioned "clamping" does not mean the contact clamping of the two inner wall surfaces of the flipping clamp 143 on the sheet. Instead, the sheet is placed in the wedge-shaped flipping clamp 143, and during the flipping process, it can come into contact with a certain inner wall surface of the wedge-shaped flipping clamp 143 to drive the sheet to flip.

[0054] In addition, as Figure 8 shown, the length L of the extension axis of the first clamping plate 1433 from the rotation axis of the flipping frame 141 is in the range of 15 - 30 mm. Such a design not only enables the flipping clamp 143 to adapt to sheets of different thicknesses, ensuring that the flipping clamp 143 can effectively "clamp" sheets of different sizes, avoiding over-tightening or over-loosening of the clamping, which may cause damage to the sheet or unstable flipping, but also can optimize the movement trajectory of the flipping clamp 143, preventing the flipping clamp 143 from colliding with other components during flipping and improving the flipping efficiency.

[0055] As Figure 2 shown, the sheet input mechanism 11 and the sheet output mechanism 12 are symmetrically arranged with respect to the flipping frame 141 in a mirror image, simplifying the operation process, improving the work efficiency, and also enhancing the stability of the device, avoiding the occurrence of offloading phenomena.

[0056] In the embodiment of the present application, the configurations of the sheet input mechanism 11 and the sheet output mechanism 12 are the same. Both of them respectively include a transmission member 111 and a driving motor 112. The driving motor 112 is connected to the transmission member 111. The driving motor 112 can drive the transmission member 111 to extend in the vertical direction relative to the frame 13 and extend to the same height as the flipping clamp 143.

[0057] It can be understood that the purpose of the transmission member 111 of the sheet input mechanism 11 extending to the same height as the flipping clamp 143 is: to be able to push the sheet from the transmission member 111 into the flipping clamp 143. The purpose of the transmission member 111 of the sheet output mechanism 12 extending to the same height as the flipping clamp 143 is: to be able to push the sheet out of the flipping clamp 143 onto the transmission member 111.

[0058] In the embodiment of the present application, the flipping driving motor 142 is a servo motor, and the driving motor 112 in the conveying mechanism is a frequency conversion motor.

[0059] Preferably, the height of the transmission member 111 can be adjusted by the driving motor 112, so that it can not only reduce the moving distance of the sheet when entering and leaving the flipping clamp 143, improve the sheet transmission efficiency, but also adapt to sheets of different thicknesses to ensure that the sheet can smoothly enter and leave the flipping clamp 143.

[0060] In the embodiment of the present application, as Figure 9 shown, a driving motor mounting bracket 133 is further provided on the frame 13 for fixedly mounting a reducer. Preferably, the driving motor mounting bracket 133 is provided in two working modules and symmetrically arranged on both sides of the frame 13 for respectively placing the two reducers on the sheet input mechanism 11 and the sheet output mechanism 12. Furthermore, the driving motor 112 is fixedly arranged on the frame 13 through the reducer.

[0061] In the embodiment of the present application, as Figure 4 shown, the sheet input mechanism 11 and the sheet output mechanism 12 are respectively provided with lifting members 131. The lifting members are arranged on the frame 13 to adjust the relative height of the sheet input mechanism 11 and the sheet output mechanism 12. That is, before conveying the sheet, the relative height of the sheet input mechanism 11 and the sheet output mechanism 12 relative to the frame 13 is manually adjusted first to ensure that the sheet can be smoothly conveyed into the flipping clamp 143 and smoothly separated from the flipping clamp 143, avoiding problems such as sheet damage caused by a large height difference. After adjusting to the required height, the subsequent sheet conveying work can be started. And during the sheet conveying work, the heights of the sheet input mechanism 11 and the sheet output mechanism 12 are not changed.

[0062] In the embodiment of the present application, the number of the flipping clips 143 is multiple, and the multiple flipping clips 143 are arranged in a circumferential array to improve the stability of flipping the "clamped" plate.

[0063] Preferably, multiple groups of flipping clips 143 are arranged on the flipping frame 141 along the direction of its extension axis, and the adjacent groups of flipping clips 143 are arranged at equal intervals in sequence. At the same time, an even number of flipping clips 143 are arranged at the same position of the flipping frame 141, so that the two flipping clips 143 symmetrically arranged with respect to the rotation axis of the flipping frame 141 can simultaneously feed and discharge the plate; in the embodiment of the present application, four flipping clips 143 are arranged at the same position of the flipping frame 141, and the interval between each two flipping clips 143 is 90°, so that parallel operation can be realized, the flipping efficiency can be improved, the flipping cycle of a single plate can be shortened, and the production efficiency can be improved. At the same time, the four flipping clips 143 at the same position rotate at an angle of 90° during rotation, which can also improve the rotation efficiency of the flipping mechanism 14 and make the flipping speed of driving the plate faster.

[0064] As Figures 4-5 shown, the transmission member 111 includes a first conveyor belt 1111, a transmission shaft 1112, a driving wheel 1113, a driven wheel 1114, and a second conveyor belt 1115.

[0065] Among them, the transmission shaft 1112 is arranged on the frame 13 and is located at one end far from the flipping frame 141, and the rotation axes of the transmission shaft 1112 and the flipping frame 141 are arranged in parallel;

[0066] The first conveyor belt 1111 is sleeved on the output shaft of the driving motor 112 and the transmission shaft 1112, the driving wheel 1113 is sleeved on the transmission wheel to be coaxially arranged with the transmission wheel, the driven wheel 1114 is arranged on the frame 13 and is located at one end close to the flipping frame 141, and the second conveyor belt 1115 is sleeved on the driving wheel 1113 and the driven wheel 1114, so that the conveying direction of the second conveyor belt 1115 is perpendicular to the direction of the rotation axis of the flipping frame 141.

[0067] In the embodiment of the present application, the first conveyor belt 1111 refers to a chain, and the second conveyor belt 1115 refers to a timing belt. In other embodiments, the configurations of the first conveyor belt 1111 and the second conveyor belt 1115 can be set as required to meet the transportation of the plate.

[0068] It can be understood that the sheet input mechanism 11 and the sheet output mechanism 12 operate independently and do not interfere with each other, that is, when the sheet needs to be transported from the sheet input mechanism 11 to the flipping mechanism 14, the drive motor 112 in the sheet input mechanism 11 is turned on; when the sheet needs to be transported from the flipping mechanism 14 to the sheet output mechanism 12, the drive motor 112 in the sheet output mechanism 12 is turned on; if multiple sheets need to be transported at the same time, the sheet input mechanism 11 and the sheet output mechanism 12 on both sides can turn on the drive motor 112 at the same time to flip the sheets continuously and uninterruptedly.

[0069] like Figure 3 As shown, the frame is further provided with an adjusting member 132, and each second conveyor belt 1115 on the sheet input mechanism 11 and the sheet output mechanism 12 is provided with the adjusting member 132, and the adjusting member 132 is connected to the second conveyor belt 1115 to adjust the height of the second conveyor belt 1115. Preferably, each second conveyor belt 1115 is provided with two adjusting members 132, and the two adjusting members 132 are respectively arranged at both ends of the second conveyor belt 1115 to achieve balanced height adjustment.

[0070] In the embodiment of the present application, the second conveyor belts 1115 on the sheet input mechanism 11 and the sheet output mechanism 12 are both arranged horizontally; preferably, the upper plane of the second conveyor belt 1115 in the sheet input mechanism 11, i.e., the extension line of the transmission surface, can pass through the rotation axis of the overturning frame 141, and in the vertical direction, the upper plane of the second conveyor belt 1115 in the sheet output mechanism 12, i.e., the extension line of the transmission surface, is 8-12 mm away from the rotation axis of the overturning frame 141, and preferably, the distance between the extension line of the upper plane of the second conveyor belt 1115 in the sheet output mechanism 12 and the rotation axis of the overturning frame 141 is 10 mm. Specifically, in the vertical direction, there is a height difference between the upper plane of the second conveyor belt 1115 in the sheet input mechanism 11 and the upper plane of the second conveyor belt 1115 in the sheet output mechanism 12. The purpose of this arrangement is that: when the flip clamp 143 drives the sheet to rotate to the side of the sheet output mechanism 12, the second clamp 1434 is in a horizontal state, and the connection end of the first clamp 1433 and the flip frame 141 is relatively low, which makes it easy for the first clamp 1433 to squeeze the sheet. Therefore, in the vertical direction, when the second conveyor belt 1115 in the sheet output mechanism 12 is in a relatively low plane, the sheet can just be completely and smoothly separated from the flip clamp 13, and naturally transition to the second conveyor belt 1115 in the sheet output mechanism 12, thereby ensuring the integrity of the sheet transportation.

[0071] Further, it also includes a conveying speed reducer 113 connected to the drive motor 112. Specifically, the conveying speed reducer 113 is connected to the transmission shaft 1112 through a first transmission belt. The drive motor 112 precisely controls the rotation angle and speed of the transmission shaft 1112 through the conveying speed reducer 113 to ensure the rotation accuracy and stability and generate sufficient torque to easily lift the plate.

[0072] Thus, taking the transportation process of the plate input mechanism 11 as an example, the power transmission process is described as follows: when the drive motor 112 operates, the conveying speed reducer 113 operates synchronously. The output shaft of the drive motor 112 is connected to the transmission shaft 1112 through the first conveyor belt 1111, and then drives the rotation of the driving wheel 1113 by driving the rotation of the transmission shaft 1112. The driving wheel 1113 is connected to the driven wheel 1114 through the second conveyor belt 1115. Thus, the plate input mechanism 11 drives the plate to move on the second conveyor belt 1115 to transport the plate to the flipping clamp 143.

[0073] In other embodiments, the overall positions of the plate input mechanism 11 and the plate output mechanism 12 can be adjusted in the front-back and up-down directions, and are not limited to the design form of this application.

[0074] It can be understood that the flipping mechanism 14 of this application also includes a flipping speed reducer 144. Thus, the power transmission process of the flipping mechanism 14 is as follows: when the flipping drive motor 142 operates, the flipping speed reducer 144 operates synchronously. The output shaft of the flipping drive motor 142 is connected to the flipping frame 141, and then drives the rotation of the flipping clamp 143 by driving the rotation of the flipping frame 141.

[0075] As Figure 4 shown, the number of driving wheels 1113 is multiple, and the multiple driving wheels 1113 are sequentially and equidistantly sleeved on the transmission shaft 1112. Thus, multiple groups of second conveyor belts 1115 drive the plate to move simultaneously, realizing the stable transportation of the plate, avoiding the shaking and deviation of the plate during transportation, and improving the production quality.

[0076] In the above structural form, each second conveyor belt 1115 and each flipping clamp 143 are sequentially arranged at intervals and cross each other without interference.

[0077] Specifically, the extension axis of the upper surface of the second conveyor belt 1115 can pass through the rotation axis of the flipping frame 141, thereby ensuring that the sheet can smoothly, stably and unobstructedly enter and exit when moving from the second conveyor belt 1115 to the flipping clamp 143 or from the flipping clamp 143 to the second conveyor belt 1115. Specifically, the extension axis of the upper surface of the second conveyor belt 1115 can pass through the center of the flipping frame 141. However, the extension axis of the first clamping plate 1433 has a certain distance L relative to the center of the flipping frame 141. Thus, when the sheet needs to be conveyed to the flipping clamp 143, the sheet can directly enter the flipping clamp 143. When the sheet needs to be removed from the flipping clamp 143, the sheet can still slide onto the second conveyor belt 1115.

[0078] Thus, based on the above structural form, the sheet can smoothly move from the second conveyor belt 1115 to the flipping clamp 143, or move back from the flipping clamp 143 to the second conveyor belt 1115 without additional guidance or adjustment, reducing the operation steps and potential operation errors.

[0079] Preferably, the sheet turning device 100 further includes a detection mechanism, and the detection mechanism includes a sheet input detection component, a flipping detection component and a sheet output detection component.

[0080] Among them, the sheet input detection component is arranged on the sheet input mechanism 11 to detect the movement of the sheet relative to the sheet input mechanism 11; the flipping detection component is arranged on the flipping mechanism 14 to detect the flipping condition of the flipping clamp 143; the sheet output detection component is arranged on the sheet output mechanism 12 to detect the position of the sheet relative to the sheet output mechanism 12.

[0081] In the embodiment of the present application, the sheet input detection component, the flipping detection component and the sheet output detection component are all sensors.

[0082] In the embodiment of the present application, the sheet input detection component specifically further includes three sensors to respectively provide an entering signal, a deceleration signal and a stop-in-place signal of the sheet.

[0083] In the embodiment of the present application, the flipping detection component specifically further includes three sensors to respectively provide the flipping origin of the flipping clamp 143 and signals for confirming whether the rotation angle is correct. Specifically, as Figure 3 and Figure 9 shown, the three sensors are all fixed on the frame 13, and the three sensors are respectively an origin detection sensor 161 and two height detection sensors 162.

[0084] Among them, the origin detection sensor 161 is arranged on the flipping motor mounting bracket 134 to detect the original position of the flipping of the flipping clamp 143;

[0085] The two height detection sensors 162 further include a high-position detection member 1621 and a low-position detection member 1622. The number of the high-position detection members 1621 and the low-position detection members 1622 is two respectively. Along the rotation axis direction of the flipping frame, the two groups of high-position detection members 1621 are symmetrically arranged on both sides of the frame, and the two groups of low-position detection members 1622 are also symmetrically arranged on both sides of the frame. That is, one high-position detection member 1621 and one low-position detection member 1622 are arranged on one side of the rotation axis of the flipping frame, and the other high-position detection member 1621 and the other low-position detection member 1622 are arranged on the other side of the rotation axis of the flipping frame. The height detection sensor 162 is used to detect the positions of the first clamping plate 1433 and the second clamping plate 1434 when the flipping clamp 143 stops. Specifically, the high-position detection member 1621 is used to detect that the position of the flipping clamp cannot be lower than a preset minimum height, and the low-position detection member 1622 is used to detect that the position of the flipping clamp cannot be higher than a preset maximum height. The two high-position detection members 1621 and the two low-position detection members 1622 are used in pairs.

[0086] If the position of the first clamping plate 1433 is too low or the position of the second clamping plate 1434 is too high, the flipping drive motor 142 rotates forward or reverses by a certain angle for position correction to avoid the position of the first clamping plate 1433 being too low and the position of the second clamping plate 1434 being too high.

[0087] In the embodiment of the present application, the sheet output detection assembly specifically further includes two sensors, which are respectively used to provide the in-position signal and the leaving signal of the sheet.

[0088] Therefore, based on the above structural form, by setting the detection mechanism to utilize the information provided by the sensors, the control system can accurately master the movement and position of the sheet in each stage, thereby realizing precise process control. And the data collected by the sensors is used to automatically adjust and optimize the operation of each mechanism, improving the automation degree of the production line. By setting the flipping detection assembly, it can not only ensure that the flipping clamp 143 starts flipping from the correct position, guaranteeing the accuracy of the flipping process, but also ensure that the flipping clamp 143 reaches the predetermined flipping angle, avoiding insufficient or excessive flipping.

[0089] Regarding the setting form and setting position of each component in the detection assembly, there is no limitation in the present application as long as it can achieve the detection function and provide the detection signal, and all belong to the protection scope of the present application.

[0090] Preferably, an origin sensing plate is installed on the flipping frame 141, and an origin detection switch and a fork position detection switch are installed on the machine frame 13. Thus, when the flipping clamp 143 drives the sheet to gradually flip to the sheet output mechanism 12 and gradually approach the second conveyor belt 1115, the flipping drive motor 142 will slow down the rotation speed of the flipping frame 141 to ensure that the sheet stops steadily on the second conveyor belt 1115. After each detection switch confirms that the positions of the sheet and the flipping clamp 143 are correct, the sheet is sent out while the next sheet is input, starting the next cycle.

[0091] In addition, the sheet flipping device 100 further includes a controller, which is communicatively connected to the drive motor 112, the flipping drive motor 142, and the detection mechanism respectively.

[0092] So that: the controller can control the operation of the drive motor 112 based on the detection information of the detection mechanism to adjust the position of the sheet relative to the flipping mechanism 14; and / or, the controller can control the operation of the flipping drive motor 142 based on the detection information of the detection mechanism to change the rotation angle of the flipping clamp 143.

[0093] Thus, based on the above structural form, the controller can automatically adjust the operation of the drive motor 112 according to the real-time detection information provided by the detection mechanism, thereby precisely controlling the position of the sheet relative to the flipping mechanism 14 to ensure the correct placement and flipping of the sheet; and, the controller uses the detection information to control the operation of the flipping drive motor 142, which can precisely adjust the rotation angle of the flipping clamp 143 to ensure that the sheet is flipped to a predetermined angle, avoiding over-flipping or insufficient flipping. Therefore, the controller can synchronously coordinate the actions of the drive motor 112 and the flipping drive motor 142 to ensure the smooth progress of the sheet input, flipping, and output processes, improving the overall efficiency of the production line.

[0094] As Figure 1 shown, protective covers 15 are also provided on both sides of the machine frame 13. The protective covers 15 are independently installed on both sides of the machine frame 13, and the number of protective covers 15 on each side is three sections. Such a setting facilitates separate disassembly without the need for hoisting equipment. At the same time, the protective covers 15 are transparent, which is convenient for observing the interior of the sheet flipping device 100. Further, a protective alarm switch can be set to enhance safety.

Correspondingly, the scope of the claims of the present application is not limited to the foregoing specific embodiments either.
