[0004] When the first conveyor line and the second conveyor line do not move relative to each other to the accurate position, that is, when their upper surfaces are flush with each other, the product may move in the transition position where the two are close to each other, thereby causing the product to fall or get stuck, resulting in product damage or scrap. Utility Model Content

[0005] The present application provides a conveying device to solve the problem that current products are prone to getting stuck or falling in lifting and conveying scenarios.

[0006] The present application provides a conveying device, which has a conveying direction and a height direction, and the product is conveyed along the conveying direction; the conveying device comprises: a first conveying platform and a second conveying platform, the first conveying platform and the second conveying platform are sequentially arranged at intervals along the conveying direction, the first conveying platform and the second conveying platform can move relative to each other in the height direction, the first conveying platform has a first surface for carrying the product in the height direction, and the second conveying platform has a second surface for carrying the product in the height direction;

[0007] and an arrester, the arrester comprising:

[0008] A blocking member, the blocking member comprising a main body and an adjusting portion, the main body being rotatably disposed at one end of the first conveying platform close to the second conveying platform;

[0009] A guide member, the guide member is arranged at one end of the second conveying platform close to the first conveying platform, the guide member is provided with a guide groove recessed in a direction away from the first conveying platform, and at least a portion of the guide groove is inclined compared to the height direction;

[0010] Wherein, the first conveying platform and the second conveying platform move relative to each other so that the adjusting part moves in the guide groove to realize switching between the anti-fall state and the flow state; in the anti-fall state, the first surface is located on the side of the second surface carrying the product in the height direction, and part of the main body is located on the side of the first surface carrying the product in the height direction; in the flow state, the first surface is flush with the second surface and the first conveying platform and the second conveying platform are relatively stationary, and the main body is flush with the first surface in the height direction.

[0011] To implement the above technical solution, when the height of the first conveyor platform is higher than that of the second conveyor platform due to control errors and other reasons, the main body part is above the first surface to block the product, thereby avoiding the jamming of the item. When the first surface is lower than the second surface, the product will be blocked by the second conveyor platform and will definitely not flow out of the first conveyor platform, and there will be no risk of falling. In addition, in this case, the guide groove has two faces to constrain the adjustment part, so as to avoid the collision and rebound caused by the adjustment part and the single inclined plane restriction in the prior art caused by the excessive speed during the descent of the item, thereby causing the main body part to rotate around the rotation axis, resulting in an unstable situation.

[0013] To implement the above technical solution, the specific structure of the guide groove is refined. The guide surface provides a guiding function, and the limit surface provides a limiting function. The combination of the two can provide a relatively stable and reliable guiding function for the adjusting part, thereby avoiding the adjustment part from colliding with the guide surface and rebounding due to excessive speed, which in turn causes the main body to rotate around the rotation axis, resulting in an unstable situation; and when the adjusting part enters the guide groove from the bottom of the guide groove, the functions of the limit surface and the guide surface are interchanged. The limit surface plays a guiding role, and the guide surface plays a limiting role. At this time, the main body can also be driven to rotate, thereby making the application scenarios of the blocker richer.

[0021] To implement the above technical solution, the first connecting member is detachably connected to the first base portion through its first waist-shaped hole so that the position of the first connecting member on the first base portion can be adjusted, and the position of the blocking member can be further adjusted, which is more convenient for installation and debugging.

The second conveying platform is equipped with a driving member that drives itself to reciprocate along the height direction. There are two blockers, and the other blocker is arranged between the ends of the second conveying platform and the third conveying platform that are close to each other.

[0024] As one of the optional embodiments of the present application, the center of gravity of the blocking member is located below the rotation axis of the blocking member in the height direction so that the blocking member forms the anti-fall state in a natural state.

[0025] To implement the above technical solution, the center of gravity of the blocking member is set so that the blocking member can complete the setting of the anti-fall state by its own gravity without external power, thereby simplifying the device structure and increasing the service life.

[0026] As one of the optional implementation schemes of the present application, a weight-reducing hole is formed through the blocking member, and the weight-reducing hole and the adjusting portion are respectively arranged at two ends of the main body.

In addition, in this case, the guide groove has two faces to constrain the adjustment part, so as to avoid the collision and rebound caused by the adjustment part and the single inclined plane restriction in the prior art during the descent of the item due to excessive speed, thereby causing the main body part to rotate around the rotation axis, resulting in an unstable situation. This case can provide a relatively stable and reliable guiding constraint effect, so that the rotation of the main body part is more stable and reliable;

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0047] The following is combined with Figure 1-6 The present application is further described.

[0048] Reference Figure 1 and Figure 2 , is a conveying device provided by the present application, the conveying device has a conveying direction X, a width direction Y and a height direction Z, the conveying direction X, the width direction Y and the height direction Z are perpendicular to each other, and the product is conveyed along the conveying direction X. The conveying device includes a first conveying platform 1, a second conveying platform 2 and a third conveying platform 7 arranged in sequence along the conveying direction X, the first conveying platform 1 and the second conveying platform 2 can move relative to each other in the height direction Z, and the second conveying platform 2 and the third conveying platform 7 can move relative to each other in the height direction Z. The implementation structure of the relative motion function is specific to this embodiment, a driving member 8 is arranged at a corresponding position of the second conveying platform 2, and the driving member 8 is arranged as a screw lifting mechanism driven by a servo motor, and the second conveying platform 2 is fixedly arranged on the lifting slider of the driving member 8 to realize the above-mentioned relative motion function. Among them, the first conveying platform 1 has a first surface 1a for carrying products in the height direction Z, the second conveying platform 2 has a second surface 2a for carrying products in the height direction Z, and the third conveying platform 7 has a third surface 7a for carrying products in the height direction Z. In this embodiment, three conveying platforms are provided, namely, a first conveying platform 1, a second conveying platform 2 and a third conveying platform 7. During the production process, the product first enters the first conveying platform 1, and the driving member 8 drives the second conveying platform 2 to move from the first conveying platform 1 to the third conveying platform 7. Figure 1 The position shown in the figure moves upward along the height direction Z until the first surface 1a is flush with the second surface 2a, and the product enters the second conveyor platform 2 from the first conveyor platform 1. Then the driving member 8 drives the second conveyor platform 2 to descend until the second surface 2a is flush with the third surface 7a, and the product enters the third conveyor platform 7 from the second conveyor platform 2.

[0049] It should be noted that the first surface 1a refers to the plane formed by the lines of the highest positions of the plurality of conveying rollers in the first conveying platform 1 in the height direction Z. The product in this embodiment refers to a transport box with a receiving groove. The second surface 2a and the third surface 7a are similar.

[0050] It should be noted that, in this embodiment, the driving member 8 is used to drive the second conveyor 2 to complete the relative movement between the first conveyor 1 and the second conveyor 2, and the relative movement between the second conveyor 2 and the third conveyor 7. However, it is not excluded that in other optional embodiments, the first conveyor 1, the second conveyor 2 or the third conveyor 7 can all move freely along the height direction Z and stop at a certain position, thereby realizing the above functions.

[0051] It should be noted that, in the present embodiment, three conveying platforms are provided, which does not exclude the possibility that the conveying platforms may be provided in two, four or other different numbers in other optional embodiments, as long as the function of relative movement between two adjacent conveying platforms is ensured.

[0052] Reference Figure 1 and Figure 2 The conveying device also includes an interceptor 3. In this embodiment, two interceptors 3 are provided, one of which is provided between the ends of the first conveying platform 1 and the second conveying platform 2 facing each other, and the other interceptor 3 is provided between the ends of the second conveying platform 2 and the third conveying platform 7 facing each other. The function of the interceptor 3 is to avoid the problem of poor product conveying that may occur when the products flow between the first conveying platform 1, the second conveying platform 2 and the third conveying platform 7 due to the misalignment between the conveying platforms. The structures of the two interceptors 3 are the same, so in this embodiment, the interceptor 3 located between the first conveying platform 1 and the second conveying platform 2 is selected for detailed description.

[0053] Reference Figure 1 , Figure 2 and Figure 3 The blocker 3 includes a blocker 31 and a guide 32. The blocker 31 includes a main body 311 and an adjusting part 312. The main body 311 is in the shape of a long strip. The main body 311 is rotatably arranged at one end of the first conveyor 1 close to the second conveyor 2. Specifically, a bearing is rotatably arranged at one end of the first conveyor 1 close to the second conveyor 2. The main body 311 is sleeved on the outer ring of the bearing to complete the setting of the rotation configuration. The adjusting part 312 is a bearing. A fixed shaft 3121 is protrudingly arranged on one side of the main body 311 close to the second conveyor 2. The inner ring of the bearing is fixedly sleeved outside the fixed shaft 3121, so that the adjusting part 312 protrudes from one side of the main body 311 close to the second conveyor 2. The guide 32 is arranged at one end of the second conveyor 2 close to the first conveyor 1. The guide 32 is in the shape of a rectangular block. A guide groove 321 is recessed on the guide 32 in the direction away from the first conveyor 1. At least part of the guide groove 321 is inclined relative to the height direction Z.

[0054] Furthermore, the relative movement between the first conveyor platform 1 and the second conveyor platform 2 enables the adjustment portion 312 to move in the guide groove 321 to switch between the anti-drop state and the flow state; in the anti-drop state, the first surface 1a is located on the side of the second surface 2a that carries the product in the height direction Z, and the main body 311 is located on the side of the first surface 1a that carries the product in the height direction Z. In the popular description of this embodiment, in the anti-drop state, the first surface 1a is higher than the second surface 2a, and the main body 311 is higher than the first surface 1a. At this time, the main body 311 will form a blocking effect on the product on the surface of the first conveyor platform 1, and the product will not flow from the first conveyor platform 1 to the second conveyor platform 2, thereby realizing the anti-drop function; in the flow state, the first surface 1a is flush with the second surface 2a and the first conveyor platform 1 and the second conveyor platform 2 are relatively stationary, and the main body 311 is flush with the first surface 1a in the height direction Z.

[0055] The above setting makes it possible that when the height of the first conveyor 1 is higher than the second conveyor 2 when the first conveyor 1 and the second conveyor 2 cooperate due to control errors or other reasons, the part of the main body 311 that is above the first surface 1a can block the product, thereby avoiding the jamming of the item. As for when the first surface 1a is lower than the second surface 2a, the product will be blocked by the second conveyor 2 and will definitely not flow out of the first conveyor 1, and there will be no risk of falling. In addition, in this case, the guide groove 321 has two faces to constrain the adjustment part 312, so as to avoid the collision and rebound caused by the adjustment part 312 and the single inclined plane restriction in the prior art during the descent of the item due to excessive speed, thereby causing the main body 311 to rotate around the rotation axis, resulting in an unstable situation. This case can provide a relatively stable and reliable guiding and restraining effect, so that the rotation of the main body 311 is more stable and reliable.

[0056] It should be noted that, refer to Figure 2 and Figure 3 , the center of gravity of the blocking member 31 is located below the rotation axis of the blocking member 31 in the height direction Z so that the blocking member 31 forms an anti-fall state in a natural state. The setting of the center of gravity of the blocking member 31 enables the blocking member 31 to complete the setting of the anti-fall state by its own gravity without the need for external power, thereby simplifying the device structure and increasing the service life. In this embodiment, the above center of gravity setting is completed by the weight of the adjustment part 312 and the weight reduction hole 31a that is opened through the main body 311. The weight reduction hole 31a and the adjustment part 312 are respectively arranged at both ends of the main body 311. In other optional embodiments, the rotation of the main body 311 can also be completed by applying power from the outside.

[0057] Reference Figure 2 and Figure 5The guide groove 321 is provided with a first opening 3211 and a second opening 3212 in sequence along the height direction Z. The first opening 3211 is located at the top end of the guide groove 321, and the second opening 3212 is located at the bottom end of the guide groove 321. The first opening 3211 and the second opening 3212 are both provided with chamfers 6. The adjustment portion 312 can enter the guide groove 321 smoothly from the first opening 3211 and the second opening 3212, further improving the stability of the adjustment process. The guide groove 321 has a guide surface 4 and a limiting surface 5 facing each other. The distance between the guide surface 4 and the limiting surface 5 is equal to the diameter of the adjustment portion 312, so that the adjustment portion 312 is placed in the guide groove 321 and contacts with the guide surface 4 and the limiting surface 5 at the same time. The guide surface 4 provides a guiding effect, and the limit surface 5 provides a limiting effect. The combination of the two can provide a relatively stable and reliable guiding effect for the adjusting part 312, thereby preventing the adjusting part 312 from colliding with the guide surface 4 and rebounding due to excessive speed, thereby causing the main body 311 to rotate around the rotation axis, resulting in an unstable situation; and when the adjusting part 312 enters the guide groove 321 from the bottom of the guide groove 321, the functions of the limit surface 5 and the guide surface 4 are interchanged. The limit surface 5 plays a guiding role, and the guide surface 4 plays a limiting role. At this time, the main body 311 can also be driven to rotate, so that the application scenarios of the blocker are richer.

[0058] Reference Figure 2 and Figure 5 The guide surface 4 includes a first surface 41 and a second surface 42 connected in sequence along the height direction Z. The second surface 42 is located on the side of the first surface 41 away from the second surface 2a. The first surface 41 is an arcuate surface, and the first surface 41 is concave in the direction away from the limiting surface 5. Since part of the guide surface 4 is an arcuate surface, the contact between the adjustment portion 312 and the guide surface 4 is smoother, and the adjustment process is more stable and smooth. The second surface 42 is parallel to the height direction Z, and the second surface 42 is connected to the first surface 41 in an arc shape. When the adjustment portion 312 abuts against the second surface 42, the main body 311 no longer rotates, indicating that the adjustment portion 312 has moved to the limit position.

[0059] Reference Figure 1 , Figure 2 and Figure 5 , the working principle of the barrier 3 is described in detail in combination with the barrier 3 between the first conveying platform 1 and the second conveying platform 2.

[0060] During the production process, the product first enters the first conveying platform 1, and the driving member 8 drives the second conveying platform 2 along the height direction Z from Figure 1The position shown in the figure moves upward until the first surface 1a is flush with the second surface 2a, and the product enters the second conveyor 2 from the first conveyor 1. At this time, if the first surface 1a is higher than the height of the second surface 2a when the driving member 8 drives the second conveyor 2 to stop running due to movement errors or other reasons, the main body 311 is higher than the height of the first surface 1a. At this time, the product is blocked by the main body 311 and cannot move from the first conveyor 1 to the second conveyor 2. This setting is because when the first conveyor 1 is higher than the second conveyor 2 and there is a height difference, the product may tip over, tilt and get stuck when it moves from the first conveyor 1 to the second conveyor 2. The above setting avoids this situation. When the product is blocked, the controller of the driving member 8 can be notified in the subsequent process to adjust the position of the second conveyor 2, and finally ensure the smooth passage of the product. Since it is not within the scope of this solution, it will not be described in detail. Similarly, the transportation logic of the blocker 3 between the second conveyor 2 and the third conveyor 7 and the implementation principle of the blocker 3 can be obtained.

[0061] Reference Figure 3 and Figure 4 The first conveying platform 1 includes a first base portion 11 and a first connecting member 12 disposed at one end of the first base portion 11 near the second conveying platform 2. The first connecting member 12 is provided with a first waist-shaped hole 12a. The first connecting member 12 is detachably connected to the first base portion 11 through the first waist-shaped hole 12a. The blocking member 31 is disposed on the first connecting member 12. The first connecting member 12 is detachably connected to the first base portion 11 through its own first waist-shaped hole 12a, so that the position of the first connecting member 12 on the first base portion 11 can be adjusted, and further the position of the blocking member 31 can be adjusted, which is more convenient for installation and debugging.

[0062] Reference Figure 3 and Figure 4 The first connecting member 12 includes a first side plate 121, a middle plate 122, and a second side plate 123 connected in sequence along the width direction Y, a first waist-shaped hole 12a is provided on the first side plate 121 and the second side plate 123, a second waist-shaped hole 122a is provided on the middle plate 122 along the width direction Y, and the middle plate 122 is bolted to the first side plate 121 and the second side plate 123 through the second waist-shaped hole 122a. The first connecting member 12 also includes a carrier plate 124, a third waist-shaped hole 124a is provided on the carrier plate 124 along the height direction Z, and the carrier plate 124 is bolted to the middle plate 122 through the third waist-shaped hole 124a, and the blocking member 31 is rotatably arranged on the carrier plate 124.

[0063] Reference Figure 5The second conveying platform 2 includes a second base part 21 and a second connecting member 22. The second connecting member 22 is provided with a fourth waist-shaped hole 22a along the width direction Y. The second connecting member 22 is bolted to the second base part 21 through the fourth waist-shaped hole 22a. The guide member 32 is arranged on the second connecting member 22. Specifically, the second connecting member 22 includes a first edge plate 221, a transition plate 222 and a second edge plate 223 connected in sequence along the width direction Y. Among them, the fourth waist-shaped hole 22a is opened on the first edge plate 221 and the second edge plate 223, and the fourth waist-shaped hole 22a extends along the height direction Z. The transition plate 222, the first edge plate 221 and the second edge plate 223 are also provided with a fifth waist-shaped hole 222a along the width direction Y. The first edge plate 221 and the transition plate 222, and the second edge plate 223 and the transition plate 222 are bolted through the fifth waist-shaped hole 222a. The guide member 32 is fixedly arranged on the transition plate 222.

[0064] The above setting allows the guide member 32 and the blocking member 31 to be fine-tuned in both the height direction Z and the width direction Y, thereby making installation and debugging more convenient and quick.
