Description

Technical Field

[0001] This utility model relates to the field of box conveying technology, and more specifically, to a flipping device. Background Technology The current market offers a wide variety of packaging equipment. Many products require flipping after being boxed to meet the requirements of subsequent palletizing processes. Existing technology typically includes a conveyor belt and a flipping rod. The box is placed on the conveyor belt and transported by the friction of the belt. During this sliding process, the box comes into contact with the flipping rod, and under the resistance of the rod, the box flips over, with each flip approximately 90°.

[0002] The inventors discovered during their research that existing box-flipping devices have at least the following drawbacks: The height of the baffle is fixed, and it can only flip boxes with a set shape, size and weight. During the flipping process, the box slips relative to the conveyor belt, causing the flipping to fail, resulting in the boxes piling up and making transportation inconvenient. Utility Model Content

[0003] The purpose of this invention includes, for example, providing a flipping device that can adaptively adjust to boxes of different sizes and weights, is not prone to slipping, and has a wide range of applications.

[0004] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a flipping device for flipping a box, comprising: A conveying mechanism and a flipping mechanism are provided. The flipping mechanism includes an angle adjustment component and a blocking component. The conveying mechanism is used to carry a target box and can convey the target box along a set direction by utilizing the friction between the conveying mechanism and the target box. The angle adjustment component is connected to the conveying mechanism. The blocking component includes a slide rod and a stop rod. The slide rod is connected to the angle adjustment component, and the stop rod is slidably connected to the slide rod in the extension direction of the slide rod. The angle adjustment component is used to adjust the angle between the slide bar and the set direction; the stop bar is used to contact the target box, and can slide relative to the slide bar under the action of the target box, and provide a flipping force to the target box after sliding to a certain height.

[0005] In an optional embodiment, the angle adjustment assembly includes an adjustment disc, a locking member, and a connecting rod; the adjustment disc is connected to the conveying mechanism, the adjustment disc is provided with an arc-shaped guide groove, the locking member is slidably engaged with the arc-shaped guide groove, and can be locked relative to the adjustment disc after sliding; the connecting rod is connected to the locking member; and the slide rod is connected to the connecting rod.

[0006] In an optional embodiment, the adjustment dial is provided with angle scale lines.

[0007] In an optional embodiment, the blocking assembly further includes a limiting member connected to the slide bar, the limiting member being used to contact the stop bar to adjust the stop bar to its lowest position on the slide bar.

[0008] In an optional embodiment, the limiting member has a lock state and an unlock state that can be switched between each other. When in the locked state, the limiting member and the slide rod are fixed relative to each other in the extension direction of the slide rod; when in the unlocked state, the limiting member and the slide rod are slidably engaged in the extension direction of the slide rod.

[0009] In an optional embodiment, the blocking assembly further includes a pulley assembly movably mounted on the slide bar, and the blocking bar is fixedly connected to the pulley assembly.

[0010] In an optional embodiment, the pulley assembly includes a base plate and at least three pulley bodies, all of which are mounted on the base plate and distributed on both sides of the slide rod to clamp the slide rod; the stop bar is connected to the base plate.

[0011] In an optional implementation, the conveying mechanism is configured as a belt conveyor.

[0012] In an optional embodiment, the stop bar is configured as a cylindrical bar.

[0013] In an optional embodiment, the number of the flipping mechanisms is multiple, and the multiple flipping mechanisms are arranged at intervals in the set direction.

[0014] The beneficial effects of this utility model embodiment include, for example: In summary, before using the flipping device provided in this embodiment, the position of the angle adjustment component is adjusted according to the weight of the target box, so that it drives the stop bar to move. The angle of the stop bar relative to the set direction is adjusted to ensure that, in the initial state, the friction between the conveying mechanism and the target box is greater than the resistance generated by the weight of the stop bar in the extension direction of the slide bar. The target box can push the stop bar to slide upward along the slide bar under the drive of the conveying mechanism, and the target box will not slip relative to the conveying mechanism. As the height of the stop bar increases, the contact position between the stop bar and the target box gradually adjusts to a position above the center of gravity of the target box. Since the flipping torque provided by the stop bar is F_torque = F_push * L, where F_push is the horizontal force applied by the stop bar to the target box, and L is the flipping lever arm (the vertical distance between the contact point of the stop bar and the target box and the center of gravity of the target box), it can be seen from this formula that the flipping torque and the flipping lever arm are positively correlated. As the flipping lever arm increases, the flipping torque increases. When the stop bar rises to a certain height, the bottom of the target box on the side closest to the stop bar first leaves the conveying mechanism. The target box rotates around the side away from the stop bar, and the target box gradually flips. When the target box flips to the point where its center of gravity is located on the vertical plane away from the stop bar, the target box completes the flip under its own weight. The stop bar, now above the target box, no longer obstructs it, and the target box can continue to be conveyed along the set direction under the drive of the conveying mechanism. Meanwhile, the stop bar slides downwards and resets under its own weight. Attached Figure Description

Detailed Implementation

[0018] 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.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] In existing technologies, box flipping is generally achieved by fixing a flipping rod above the conveyor belt. As the box approaches the flipping rod under the action of the conveyor belt, the front side of the box contacts the flipping rod, and the box is blocked by the flipping rod. The front side of the box tilts upward, and the bottom surface forms an angle with the conveyor belt. As the box continues to approach the flipping rod, the angle gradually increases, eventually completing the flipping. Because the height of the flipping rod is fixed, and its position cannot be adjusted when it contacts the box, its flipping torque is fixed. When the size or weight of the box changes, there is a possibility that the box will slip on the conveyor belt and fail to flip. In other words, the existing flipping rod technology is only suitable for flipping boxes of specific sizes and weights, and its application range is limited.

[0025] In view of this, the designers have provided a flipping device that can adaptively adjust the flipping torque, adapt to the flipping of boxes of different sizes and weights, has a wide range of applications, and is less likely to cause boxes to slip and stack, which is beneficial for flipping and transporting boxes.

[0026] Please refer to Figures 1-3 This embodiment provides a flipping device for flipping a box, which can be a cube or cuboid shape, etc. The flipping device includes a conveying mechanism 100 and a flipping mechanism 200. The flipping mechanism 200 includes an angle adjustment component 210 and a blocking component 220. The conveying mechanism 100 is used to carry the target box 001 and can transport the target box 001 along a set direction 002 by utilizing the friction between the conveying mechanism 100 and the target box 001. The angle adjustment component 210 is connected to the conveying mechanism 100. The blocking component 220 includes a slide rod 221 and a stop rod 222. The slide rod 221 is connected to the angle adjustment component 210, and the stop rod 222 is slidably connected to the slide rod 221 in the extending direction of the slide rod 221. The angle adjustment component 210 is used to adjust the angle between the slide bar 221 and the set direction 002; the stop bar 222 is used to contact the target box 001, and can slide relative to the slide bar 221 under the drive of the target box 001, and provide a flipping force to the target box 001 after sliding to a certain height.

[0027] As described above, the working principle of the flipping device provided in this embodiment is as follows: Before use, adjust the position of the angle adjustment component 210 according to the weight of the target box 001, so that it drives the stop bar 222 to move. Adjust the angle of the stop bar 222 relative to the set direction 002 to ensure that in the initial state, the friction between the conveying mechanism 100 and the target box 001 is greater than the resistance generated by the weight of the stop bar 222 in the extension direction of the slide bar 221. The target box 001 can push the stop bar 222 to slide upward along the slide bar 221 under the drive of the conveying mechanism 100, ensuring that the target box 001 will not slip relative to the conveying mechanism 100. As the height of the stop lever 222 increases, the contact position between the stop lever 222 and the target box 001 is gradually adjusted to a position above the center of gravity of the target box 001. Since the flipping torque F_torque = F_push * L provided by the stop lever 222, where F_push is the horizontal force applied by the stop lever 222 to the target box 001 and L is the flipping lever arm, which is the vertical distance between the contact point between the stop lever 222 and the target box 001 and the center of gravity O of the target box 001, according to this formula, the flipping torque and the flipping lever arm are positively correlated. As the flipping lever arm increases, the flipping torque increases. When the stop lever 222 rises to a certain height, the bottom of the side of the target box 001 closest to the stop lever 222 leaves the conveying mechanism 100 first, and the target box 001 rotates around the side away from the stop lever 222, and the target box 001 gradually flips. When the target box 001 flips to the side where its center of gravity is located on the vertical plane away from the stop bar 222, the target box 001 completes the flip under its own gravity. The stop bar 222 is above the target box 001 and will no longer block the target box 001. The target box 001 can continue to be conveyed along the set direction 002 under the drive of the conveying mechanism 100, while the stop bar 222 slides down and resets under its own gravity.

[0028] In other words, please combine Figure 4 and Figure 5 As the stop lever 222 and the target box 001 change from position 1 to position 2, L gradually increases, and the flipping torque gradually increases. When the flipping torque increases to the set value, it can make the left side of the target box 001 leave the conveying mechanism 100 first and start the clockwise flipping action until the stop lever 222 contacts position 3 on the target box 001. At this time, the center of gravity O of the target box 001 is located on the right side of the vertical axis Y. Under the action of gravity, the target box 001 automatically completes the clockwise flipping.

[0029] The following embodiments illustrate the details of the flipping device of this application by way of example.

[0030] Please refer to Figures 1-5In this embodiment, optionally, the flipping device includes a conveying mechanism 100 and a flipping mechanism 200. The conveying mechanism 100 can convey the target box 001 along a set direction 002. There can be two flipping mechanisms 200, arranged at intervals along the set direction 002. Each flipping mechanism 200 can flip the target box 001 90° on the conveying mechanism 100. The two flipping mechanisms 200 working together can flip the target box 001 180° on the conveying mechanism 100. When it is necessary to flip the target box 001 180°, the two flipping mechanisms 200 working together decompose the flipping action of the target box 001, reducing the difficulty of flipping.

[0031] In this embodiment, optionally, the conveying mechanism 100 can be configured as a belt conveyor mechanism 100. The belt conveyor mechanism 100 can refer to existing known structures; for example, it includes a support, a conveyor belt, a motor, a drive pulley, and a driven pulley. The support can be fixed to the ground, the motor is fixed to the support, and both the drive pulley and the driven pulley are rotatably connected to the support. The axes of the drive pulley and the driven pulley are parallel and spaced apart in a set direction 002. The conveyor belt is simultaneously supported and tensioned by both the drive pulley and the driven pulley. The motor is connected to the drive pulley and can drive it to rotate, causing the conveyor belt to rotate due to friction. The conveyor belt has two horizontal sections, distributed vertically, with the target box 001 placed on the upper horizontal section. The target box 001 has friction with the conveyor belt, and the target box 001 is conveyed by this friction. The frictional force between the target box 001 and the conveyor belt, F_friction = G_box * u, where G_box is the weight of the target box 001 (a known quantity), and u is the coefficient of friction (a known quantity). F is proportional to the weight of the target box 001.

[0032] It should be noted that when placing the target box 001 on the conveyor belt for transport, the weight of the target box 001 can be obtained first using a weighing mechanism to confirm the magnitude of the friction.

[0033] The weighing mechanism can refer to existing known structures, and is not specifically limited in this embodiment. The transfer of the target box 001 between the weighing mechanism and the conveying mechanism 100 can be achieved by a robotic arm or the like.

[0034] In this embodiment, optionally, the two flipping mechanisms 200 can be configured to have the same structure and the same working principle. In order to avoid repetition and redundancy, this embodiment will use the specific structure and working principle of one flipping mechanism 200 as an example for explanation.

[0035] In this embodiment, optionally, the flipping mechanism 200 includes an angle adjustment component 210 and a blocking component 220. The angle adjustment component 210 is mounted on the bracket and connected to the blocking component 220, which can adjust the angle of the blocking component 220 to adapt to target boxes 001 of different sizes and weights.

[0036] Optionally, the adjustment assembly includes an adjustment disc 211, a locking element 212, and a connecting rod 213. The adjustment disc 211 can be a protractor disc, meaning it has angle scale lines for determining angles. The adjustment disc 211 can be fixed to the side of the bracket using bolts or other structural components. The locking element 212 can be a bolt, with one end connected to the connecting rod 213. The locking element 212 can move relative to the adjustment disc 211 and lock after movement. The connecting rod 213 is rotatably connected to the adjustment disc 211 and can connect to the blocking assembly 220. With this design, when adjusting the angle of the blocking assembly 220, the locking element 212 is first unlocked relative to the adjustment disc 211, and then the connecting rod 213 is rotated. The connecting rod 213 drives the locking element 212 and the blocking assembly 220 to rotate. The angle of rotation of the connecting rod 213 can be directly obtained from the angle scale lines on the adjustment disc 211, making angle adjustment convenient and accurate. After the angle is adjusted, the connecting rod 213 is locked onto the adjusting plate 211 by the locking member 212. The angle of the connecting rod 213 is locked, which also locks the blocking component 220.

[0037] It should be understood that in other embodiments, the angle of the connecting rod 213 can be monitored in real time by an angle measuring instrument, and the angle value can be prompted by voice broadcast or display screen.

[0038] Optionally, the adjusting disc 211 is provided with an arc-shaped groove 2111 surrounding the rotation center of the connecting rod 213. That is, the arc-shaped groove 2111 is an arc segment, and the center of the circumference of the arc-shaped groove 2111 coincides with the rotation center of the connecting rod 213. The locking member 212 can move in the arc-shaped groove 2111, thereby improving stability.

[0039] It should be understood that the locking element 212 can be a bolt or the like, for ease of operation.

[0040] Optionally, the blocking assembly 220 includes a slide rod 221, a stop rod 222, a limiting member 223, and a pulley block 224. The slide rod 221 is fixed to the connecting rod 213, and the two can be connected by bolts or other structural components. The slide rod 221 can be perpendicular to the connecting rod 213, which improves structural compactness and space utilization. The limiting member 223 can be a sleeve, fitted over the slide rod 221. The limiting member 223 can be connected to the slide rod 221 by bolts or other structural components, and it has a switchable locked state and an unlocked state. That is, when the bolt is tightened, the limiting member 223 is locked on the slide rod 221, and the limiting member 223 will not slide relative to the slide rod 221 in the extension direction of the slide rod 221. Correspondingly, when the bolt is loosened, the limiting member 223 can slide relative to the slide rod 221 in the extension direction of the slide rod 221, thereby adjusting the position of the limiting member 223. After the adjustment is completed, the bolt is tightened again to lock the limiting member 223.

[0041] Meanwhile, the pulley assembly 224 includes a base plate 2241 and pulley bodies 2242. There are multiple pulley bodies 2242, and more specifically, at least three, which improves stability. Specifically, in this embodiment, there are three pulley bodies 2242, all mounted on the base plate 2241. The three pulley bodies 2242 are distributed on both sides of the slide rod 221 to clamp it. The pulley bodies 2242 are in contact with the slide rod 221, resulting in low friction and easy sliding. The stop rod 222 is connected to the base plate 2241, and the stop rod 222 and pulley bodies 2242 are distributed on opposite sides of the base plate 2241. By clamping the slide rod 221 with the three pulley bodies 2242, not only can the stop rod 222 slide flexibly in the extension direction of the slide rod 221, but the pulley bodies 2242 also remain in place, improving structural stability and reliability.

[0042] Obviously, in other embodiments, the number of pulley bodies 2242 can also be two, four, etc.

[0043] It should be noted that the lowermost pulley body 2242 of the pulley body 2242 can contact the limiting member 223. That is, under the action of gravity, the pulley assembly 224 and the stop bar 222 together have a tendency to slide downward along the extension direction of the slide bar 221. When they slide to contact the limiting member 223, the pulley assembly 224 can no longer slide, thus determining the initial position of the stop bar 222. Since the position of the limiting member 223 is adjustable, the initial position of the stop bar 222 can be adjusted according to needs, making it flexible in use.

[0044] That is, in the initial stage when the target box 001 contacts the stop bar 222, the target box 001 needs to drive the stop bar 222 to slide upward along the extension direction of the slide bar 221, gradually increasing the overturning torque. Therefore, in order to reduce the sliding distance of the stop bar 222 and reduce the wear between the two, the initial position of the stop bar 222 is generally adjusted to a position above the center of gravity of the target box 001.

[0045] It is worth noting that in the initial stage, the target box 001 needs to push the stop lever 222 and the pulley block 224 together to slide relative to the slide rod 221. This requires overcoming the resistance F generated by the sum of the weights of the stop lever 222 and the pulley block 224 in the extension direction of the slide rod 221. The magnitude of the resistance F is related to the angle α between the slide rod 221 and the set direction 002. Therefore, before transporting the target box 001, the friction F can be calculated first. Then, based on the fact that friction F > resistance F, the range of values ​​for α can be obtained. Finally, the angle adjustment component 210 can be used to adjust α to any value within the range.

[0046] It should be understood that the two flipping mechanisms 200 are designed independently and can work independently without affecting each other.

[0047] The flipping device provided in this embodiment, through the cooperation of two flipping mechanisms 200, enables the target box 001 located on the conveyor belt to perform two 90° flipping actions respectively, and finally realizes the flipping of the target box 001°. It is easy to operate, and the flipping mechanism 200 can adaptively adjust the flipping torque according to the size and weight of the target box 001, making the flipping smoother and with a wide range of applications.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
