For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Reference below Figure 1-Figure 17 A conveying device 100 according to an embodiment of the present invention is described.

[0042] like Figure 1 As shown, the conveying device 100 according to the embodiment of the present utility model includes a body 1 , a first conveying unit 21 , a second conveying unit 22 , a first lifting unit 41 and a rotating unit 6 .

[0043] Please refer to the attached Figure 8 The first conveying unit 21 is provided on the machine body 1 and can convey articles along a first direction. The second conveying unit 22 is provided on the machine body 1 and embedded in the first conveying unit 21 and can convey articles along a second direction, which intersects with the first direction.

[0044] like Figure 8 and Fig. 9 As shown, the first lifting unit 41 can drive the second conveying unit 22 to rise and fall relative to the first conveying unit 21 to adjust the height of the second conveying unit 22 relative to the first conveying unit 21. Since the second conveying unit 22 is embedded in the first conveying unit 21, the items on the second conveying unit 22 can be transferred to the first conveying unit 21, or the items on the first conveying unit 21 can be transferred to the second conveying unit 22.

[0045] For example, the second transmission unit 22 Fig. 9 The height position shown moves down to Figure 8 When the height position is shown, the articles on the second conveying unit 22 are conveyed to the first conveying unit 21; of course, the second conveying unit 22 is automatically Figure 8 The height position shown moves up to Fig. 9 When in the height position shown, the articles on the first conveying unit 21 can be conveyed to the second conveying unit 22 .

[0046] Exemplarily, when the conveying device 100 is used, it can include at least two of the following multiple usage modes: 1. Articles conveyed along the first direction can be conveyed to the first conveying unit 21 along the first direction, and conveyed to the designated position through the first conveying unit 21; 2. Articles conveyed along the second direction can be conveyed to the second conveying unit 22 along the second direction, and conveyed to the designated position; 3. Articles conveyed along the first direction can be conveyed to the first conveying unit 21 along the first direction, and conveyed to the second conveying unit 22 through the first conveying unit 21, and then conveyed to the designated position through the second conveying unit 22; 4. Articles conveyed along the second direction can be conveyed to the second conveying unit 22 along the second direction, and conveyed to the first conveying unit 21 through the second conveying unit 22, and then conveyed to the designated position through the first conveying unit 21.

[0047] It can be seen that the second conveying unit 22 is embedded in the first conveying unit 21 , making the structure of the conveying device 100 more compact, which is beneficial to reducing the space occupied by the conveying device 100 and facilitating mutual transmission between the first conveying unit 21 and the second conveying unit 22 .

[0048] like Fig.15 As shown, that is, the objects can enter the conveying device 100 from the first direction and the second direction, and be conveyed to the designated location by the conveying device 100. In the conveying process of the objects, no manual handling is required, and the conveying device 100 can convey objects from different directions, which is conducive to reducing labor intensity, improving the automation degree of the conveying device 100, and improving the conveying efficiency.

[0049] like Figure 3 , Figure 4 and Figure 6 As shown, the rotating unit 6 can drive the first conveying unit 21 and the second conveying unit 22 to rotate synchronously around the preset axis N, so that the first conveying unit 21 and the second conveying unit 22 rotate relative to the machine body 1, and the preset axis N is perpendicular to the conveying surface of the first conveying unit 21. Before the rotation, the first conveying unit 21 and the second conveying unit 22, the first conveying unit 21 can receive and convey objects from the first direction, and the second conveying unit 22 can receive and convey objects from the second direction; after the rotation, the conveying direction of the first conveying unit 21 and the conveying direction of the second conveying unit 22 are changed, wherein the first direction and the second direction intersect. In summary, by driving the first conveying unit 21 and the second conveying unit 22 to rotate by the rotating unit 6, the conveying device 100 can receive and convey objects from multiple directions, thereby improving the efficiency of the conveying and the versatility of the conveying device 100. At the same time, the posture of the objects sent from the conveying device 100 can be adjusted by the rotating unit 6, that is, the placement posture of the objects sent to the conveying device 100 can be the same or different from the posture of the objects sent from the conveying device 100.

[0050] For example, with the first direction and the second direction being perpendicular, the article is first conveyed to the second conveying unit 22, the second conveying unit 22 descends to convey the article to the first conveying unit 21, and then the first conveying unit 21 conveys the article. In the above process, the rotating unit 6 does not work, that is, the conveying directions of the first conveying unit 21 and the second conveying unit 22 do not change. After the article passes through the conveying device 100, its conveying direction changes by 90°, and its conveying posture does not change; or, the article is first conveyed to the second conveying unit 22, and then the rotating unit 6 drives the second conveying unit 22 to rotate 90°, and then the second conveying unit 21 rotates by 90°. If the conveying unit 22 continues to convey the article, the conveying direction and conveying posture of the article will change after passing through the conveying device 100; or, the article is first conveyed to the first conveying unit 21 (if the first conveying unit 21 is not in the same direction as the direction in which the article is conveyed, the rotating unit 6 can first drive the first conveying unit 21 to rotate so that the direction in which the article is conveyed is consistent with the conveying direction of the first conveying unit 21), and then the rotating unit 6 drives the first conveying unit 21 to rotate 90°, and then the first conveying unit 21 continues to convey the article, then the conveying direction and conveying posture of the article will change after passing through the conveying device 100; but it is not limited to this.

[0051] It can be seen that when the conveying device 100 is used to transport items to the detection device, since the detection device has requirements for the placement posture of the item, after detecting the placement posture of the item and judging whether the placement posture of the item is the same as the placement posture requirement of the detection device, if they are the same, there is no need to change the placement posture of the item when conveying it through the conveying device 100. If they are different, the placement posture of the item is changed at the same time when conveying it through the conveying device 100.

[0052] Of course, the rotation angle range of the first conveying unit 21 and the second conveying unit 22 driven by the rotating unit 6 can be specifically set according to actual needs, for example, it can be rotated within a range of 90°, 280°, or 360°.

[0053] Please refer to the attached Fig.16, in the conveying direction of the first conveying unit 21, the distance between one end of the first conveying unit 21 and the preset axis N is L11, and the distance between the other end of the first conveying unit 21 and the preset axis N is L12; in the conveying direction of the second conveying unit 22, the distance between one end of the second conveying unit 22 and the preset axis N is L21, and the distance between the other end of the second conveying unit 22 and the preset axis N is L22, wherein at least one of L11 and L12 is equal to at least one of L21 and L22, including the following schemes: 1. L12≠L11=L21≠L22; 2. L12≠L11=L21=L22; 3. L12=L11=L21=L22; 4. L12=L11=L21≠L22.

[0054] Therefore, when the articles rotate with the first conveying unit 21, the articles are placed more stably on the conveying device 100, which is beneficial to maintaining the balance of the articles and reducing the probability of damage. Moreover, no matter whether the at least one end of the first conveying unit 21 in the conveying direction is used to receive foreign articles, or the at least one end of the second conveying unit 22 in the conveying direction is used to receive foreign articles, the receiving positions in the above two states are at an equal distance from the preset axis. The first conveying unit 21 and the second conveying unit 22 can provide basically consistent receiving references when receiving foreign articles in the above two different states, so that the first conveying unit 21 and the second conveying unit 22 can stably receive foreign articles at the same time, and it is not easy for foreign articles to fall due to the large difference in the receiving positions of the first conveying unit 21 and the second conveying unit 22, and it will have high requirements for coordination with other conveying units.

[0055] The following description is made by taking as an example that the distance L11 between one end of the first conveying unit 21 in the conveying direction and the preset axis N is equal to the distance L21 between one end of the second conveying unit 22 in the conveying direction and the preset axis N. It should be pointed out that the specific examples are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the conveying device 100 referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0056] When the rotating unit 6 drives the first transmission unit 21 and the second transmission unit 22 to rotate synchronously around the preset axis N, the motion trajectory of one end of the first transmission unit 21 and the motion trajectory of one end of the second transmission unit 22 are the same and circular, wherein the circular motion trajectory takes the preset axis N as the center and L11 as the radius. Therefore, it is only necessary to keep a certain distance between the first transmission unit 21 and other matching parts (such as the third transmission unit 23 and the fourth transmission unit 24 in the figure) or only to keep a certain distance between the second transmission unit 22 and other matching parts (such as the third transmission unit 23 and the fourth transmission unit 24 in the figure), and the first transmission unit 21 and the second transmission unit 22 will not interfere with other matching parts, which is conducive to simplifying the layout of the transmission device 100 and increasing the transmission range of the transmission device 100.

[0057] Optionally, the distance L12 between the other end of the first conveying unit 21 and the preset axis N is equal to the distance L21 between one end of the second conveying unit 22 and the preset axis N; optionally, the distance L12 between the other end of the first conveying unit 21 and the preset axis N is equal to the distance L22 between the other end of the second conveying unit 22 and the preset axis N; optionally, the distance L11 between one end of the first conveying unit 21 and the preset axis N is equal to the distance L22 between the other end of the second conveying unit 22 and the preset axis N.

[0058] In the related art, the rotating component can drive the first conveying unit and the second conveying unit to rotate, but the transportable range of the second conveying unit is smaller than that of the first conveying unit, and the first conveying unit can only realize the operation of rotating after conveying the items to the second conveying unit. In the present application, the second conveying unit 22 is embedded in the first conveying unit 21, and the second conveying unit 22 can receive and convey the items to the first conveying unit 21, thereby increasing the conveying range of the second conveying unit 22, thereby increasing the conveying range of the conveying device 100, and increasing the conveying scheme of the conveying device 100.

[0059] An optional conveying scheme S1 is: the first lifting unit 41 drives the second conveying unit 22 to rise above the conveying surface of the first conveying unit 21, and the items are conveyed to the second conveying unit 22; the first lifting unit 41 drives the second conveying unit 22 to descend, so that the items on the second conveying unit 22 are conveyed to the first conveying unit 21 and continue to be conveyed through the first conveying unit 21.

[0060] An optional conveying scheme S2 is: the first lifting unit 41 drives the second conveying unit 22 to descend so that the conveying surface of the second conveying unit 22 is lower than the conveying surface of the first conveying unit 21, and the items are conveyed to the first conveying unit 21; the first lifting unit 41 drives the second conveying unit 22 to rise so that the items on the first conveying unit 21 are conveyed to the second conveying unit 22, and continue to be conveyed through the second conveying unit 22.

[0061] An optional conveying scheme S3 is: the first lifting unit 41 drives the second conveying unit 22 to rise above the conveying surface of the first conveying unit 21, the items are conveyed to the second conveying unit 22, the rotating unit 6 drives the second conveying unit 22 to rotate to change the conveying direction of the second conveying unit 22 until the requirements are met, and the items are continued to be conveyed through the second conveying unit 22.

[0062] An optional conveying scheme S4 ​​is: the first lifting unit 41 drives the second conveying unit 22 to descend so that the conveying surface of the second conveying unit 22 is lower than the conveying surface of the first conveying unit 21, the items are conveyed to the first conveying unit 21, and the rotating unit 6 drives the second conveying unit 21 to rotate to change the conveying direction of the first conveying unit 21 until the requirements are met, and continue to be conveyed through the first conveying unit 21.

[0063] It is understandable that the transmission scheme can also be other combinations of the above transmission steps. In a specific example, an appearance detection mechanism is required to detect the appearance of the object, and the appearance detection device needs to specify the placement posture of the object to avoid misjudgment and wrong judgment. The transmission device 100 of the present application can change the placement posture of the object through a combination of multiple transmission schemes, which is conducive to reducing the labor input of workers and further improving the degree of automation.

[0064] The difference from the prior art is that the transmission range of the second transmission unit 22 is expanded, and thus the transmission range of the transmission device 100 is expanded. The transmission device 100 can implement multiple transmission schemes, among which the second transmission unit 22 can directly transmit the items to the first transmission unit 21, simplifying the steps of transmitting the items, which is conducive to reducing the transmission time and improving the transmission efficiency.

[0065] According to the conveying device 100 of the embodiment of the utility model, the first conveying unit 21 and the second conveying unit 22 are driven to rotate around the preset axis by the rotating unit 6, and the conveying device 100 can receive and convey items from multiple directions, thereby improving the efficiency of conveying, and the placement posture of the items after being conveyed by the conveying device 100 can be adjusted or adjusted accordingly according to actual needs. At the same time, when the first conveying unit 21 and other matching components can maintain a suitable distance, the first conveying unit 21 and the second conveying unit 22 will not interfere with other matching components, which is conducive to simplifying the layout of the conveying device 100, and also improves the transmission range of the conveying device 100, and increases the transmission scheme of the conveying device 100. The preset axis N is perpendicular to the conveying surface of the first conveying unit 21, so that when the items rotate with the first conveying unit 21, the items are placed more stably on the conveying device 100, which is conducive to maintaining the balance of the items and reducing the probability of damage.

[0066] like Figure 2 As shown, in some embodiments, the conveying device 100 further includes a third conveying unit 23. The third conveying unit 23 is spaced apart from the first conveying unit 21, and the third conveying unit 23 is arranged on one side of the first conveying unit 21 in the third direction and is used to convey articles along the third direction. The third conveying unit 23 can receive articles conveyed to at least one of the two ends of the first conveying unit 21 in the conveying direction, or the third conveying unit 23 can receive articles conveyed to at least one of the two ends of the second conveying unit 22 in the conveying direction.

[0067] The rotating unit 6 can drive the first conveying unit 21 and the second conveying unit 22 to rotate, so that the conveying direction of the second conveying unit 22 is parallel to the conveying direction of the third conveying unit 23. At this time, the third conveying unit 23 can receive the items at at least one of the two ends of the second conveying unit 22 in its conveying direction, and continue to convey them along the third direction; or, the rotating unit 6 can drive the first conveying unit 21 and the second conveying unit 22 to rotate, so that the conveying direction of the first conveying unit 21 is parallel to the conveying direction of the third conveying unit 23. The third conveying unit 23 can receive the items at at least one of the two ends of the first conveying unit 21 in its conveying direction, and continue to convey them along the third direction.

[0068] The conveying device 100 further includes a fourth conveying unit 24, which is spaced apart from the first conveying unit 21. The first conveying unit 21 is provided with the fourth conveying unit 23 on at least one of the two sides in the fourth direction. The fourth conveying unit 23 is used to convey articles toward at least one of the two ends of the first conveying unit 21 in the conveying direction, and / or the fourth conveying unit 24 is used to convey articles toward at least one of the two ends of the second conveying unit 22 in the conveying direction. Thus, the conveying device 100 can realize the conveying of articles on the fourth conveying unit 23 to the third conveying unit 23, and at the same time, it is convenient to further enrich the conveying mode of the conveying device 100.

[0069] Combination Figure 5 and Fig.16 From the perspective of FIG. 6 , the rotating unit 6 can drive the first conveying unit 21 and the second conveying unit 22 to rotate, so that the conveying direction of the second conveying unit 22 is parallel to the conveying direction of the fourth conveying unit 24. At this time, the fourth conveying unit 24 can receive the items at at least one of the two ends of the second conveying unit 22 in its conveying direction, and continue to convey them along the fourth direction; of course, the first conveying unit 22 can also receive the items on the fourth conveying unit 24, which will not be repeated here.

[0070] like Figure 5 and Fig.16 As shown, in some embodiments, the conveying device 100 further includes a second lifting unit 42, which can drive the first conveying unit 21 and the second conveying unit 22 to rise and fall synchronously relative to the machine body 1, so as to adjust the height of the first conveying unit 21 and the second conveying unit 22, so as to enable the first conveying unit 21 and the second conveying unit 22 to receive and convey items with corresponding height positions. For example, the height positions of the items before and after being conveyed by the conveying device 100 are the same or different. The rotating unit 6 drives the first conveying unit 21 and the second conveying unit 22 to rotate through the second lifting unit 42; or, the second lifting unit 42 drives the first conveying unit 21 and the second conveying unit 22 to rise and fall through the rotating unit 6.

[0071] Among them, the rotating unit 6 can drive the first conveying unit 21 and the second conveying unit 22 at a preset height position to rotate. At the preset height position, the first conveying unit 21 and the second conveying unit 22 are both arranged to avoid the third conveying unit 23 and the fourth conveying unit 24 in the up and down directions, so that the first conveying unit 21 and the third conveying unit 23 are separated in height, so that the rotation of the first conveying unit 21 and the second conveying unit 22 is smoother and less susceptible to interference from the third conveying unit 23, thereby improving the stability and efficiency of the transmission, and the transmission interval between the first conveying unit 21 and the third conveying unit 23, and the transmission interval between the first conveying unit 21 and the fourth conveying unit 24 can be set to be relatively small, which is beneficial to improving the compactness of the structure of the conveying equipment 100 and saving occupied space.

[0072] For example, the rotating unit 6 drives the first conveying unit 21 and the second conveying unit 22 to rotate through the second lifting unit 42. The conveying end of the first conveying unit 21 is adjacent to the conveying start end of the third conveying unit 23, and the article can be more smoothly conveyed from the first conveying unit 21 to the third conveying unit 23; or, the conveying end of the second conveying unit 22 is adjacent to the conveying start end of the third conveying unit 23, and the article can be more smoothly conveyed from the second conveying unit 22 to the third conveying unit 23. When it is necessary to rotate the first conveying unit 21 and the second conveying unit 22, the first conveying unit 21 and the second conveying unit 22 are raised by the second lifting unit 42, so that the first conveying unit 21 is spaced apart from the third conveying unit 23 in height, so that the rotation of the first conveying unit 21 is smoother and less susceptible to interference from the third conveying unit 23, thereby improving the stability and efficiency of the conveying. For example, if it is necessary to transfer items on the second conveying unit 22 to the third conveying unit 23, the second conveying unit 22 can be lifted by the second lifting unit 42, and the second conveying unit 22 can be rotated by the rotating unit 6 to a position where its conveying direction is consistent with the conveying direction of the third conveying unit 23, and then the second conveying unit 22 can be lowered to be flush with the third conveying unit 23.

[0073] like Figure 5 As shown, in some embodiments, the conveying surface of the third conveying unit 23 is flush with the conveying surface of the fourth conveying unit 24. Therefore, the first conveying unit 21 and the second conveying unit 22 can convey the articles on the third conveying unit 23 to the fourth conveying unit 24, and the conveying height positions of the front and rear articles are consistent. During the conveying process of the articles, the articles can be conveyed at the same height, reducing the bumps during the conveying process and making the conveying more stable.

[0074] like Figure 3 , Figure 4 and Figure 7As shown, in some embodiments, the conveying device 100 further includes a mounting plate 7, the first conveying unit 21, the second conveying unit 22 and the rotating unit 6 are all mounted on the mounting plate 7, and the second lifting unit 42 cooperates with the mounting plate 7 to directly drive the mounting plate 7 to rise and fall. The mounting plate 7 and the machine body 1 slide up and down through the first guide structure 31, the first guide structure 31 includes a first guide hole 311 and a first guide column 312 slidingly matched with the first guide hole 311, and there are multiple first guide structures 31, and at least two of the multiple first guide structures 31 are arranged at the corner positions of the mounting plate 7. The mounting plate 7 carries the first conveying unit 21 and the second conveying unit 22, and the second lifting unit 42 abuts against the mounting plate 7 and lifts the mounting plate 7, and can synchronously lift the positions of the first conveying unit 21 and the second conveying unit 22, with a simple structure and high reliability. The first guide structure 31 guides the movement of the mounting plate 7, which is conducive to a more stable movement of the mounting plate 7. When multiple first guide structures 31 are provided, the stability of the movement of the mounting plate 7 can be further improved.

[0075] like Figure 7 As shown, for example, the second lifting unit 42 includes a second lifting motor 421 and a second lifting mechanism 422, the second lifting mechanism 422 includes a second lifting machine 4221 and a second lifting platform 4222, the second lifting platform 4222 abuts against the mounting plate 7, and the second lifting machine 4221 can transmit the driving force of the second lifting motor 421 to the second lifting platform 4222, so that the second lifting platform 4222 drives the mounting plate 7 to rise and fall.

[0076] like Figure 7 As shown, in some embodiments, the rotating unit 6 includes a third driver 61 and a rotating module 62. The third driver 61 drives the first conveying unit 21 and the second conveying unit 22 to rotate through the rotating module 62. A part of the rotating module 62, the first conveying unit 21 and the second conveying unit 22 are all arranged on the upper side of the mounting plate 7, and another part of the rotating module 62, the third driver 61 and the second lifting unit 42 are arranged on the lower side of the mounting plate 7. The upper end of the rotating module 62 is connected to the mounting plate 7, the driver drives the rotating module 62 to rotate, and the rotating module 62 drives the mounting plate 7 to rotate. A part of the rotating module 62 is arranged on the upper side of the mounting plate 7, which is conducive to the connection between the rotating module 62 and the mounting plate 7 and improves the convenience of assembly. The first conveying unit 21 and the second conveying unit 22 are arranged on the upper side of the mounting plate 7, and the other part of the rotating module 62 and the third driver are arranged on the lower side of the mounting plate 7, so as to make full use of the height space and make the structure more compact.

[0077] like Figure 6 As shown, for example, a mounting plate avoidance portion 71 is provided on the mounting plate 7 to allow a portion of the rotating module to pass through.

[0078] like Figure 2 , Figure 15-17 As shown, in some embodiments, the conveying device 100 also includes a centering unit 5, the centering unit 5 includes a first limit group 51 and a second limit group 52, the first limit group 51 and the second limit group 52 are respectively embedded in the third conveying unit 23 and can respectively move synchronously relative to the third conveying unit 23 along the fourth direction, and the moving directions of the first limit group 51 and the second limit group 52 are opposite, the first limit group 51 and the second limit group 52 can move relative to each other or move back to back, the fourth direction is perpendicular to the third direction, and the centering unit 5 adjusts the posture of the object so that the object can be placed according to the preset posture when it arrives at the specified position, thereby improving the degree of automation and reliability of the conveying.

[0079] For example, when the appearance of an object is to be inspected, the appearance inspection device needs to specify the placement posture of the object to avoid misjudgment and wrong judgment. The third conveying unit 23 and the centering unit 5 embedded thereon can convey the object to a designated location, and during the conveying process, the centering unit 5 adjusts the object according to the preset posture, thereby improving the automation and reliability of the conveying.

[0080] It should be further explained that the first limiting group 51 and the second limiting group 52 are arranged relatively to each other and can respectively abut against the two ends of the object in the fourth direction. The outer contour of the object is tangent to the first limiting group 51 and the second limiting group 52, so that the object is placed in a preset posture.

[0081] like Figure 2 As shown, in combination with the above embodiment, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the fourth direction. Under the premise that the centering unit 5 and the rotating unit 6 are inactive, the first direction is parallel to the third direction, that is, the movement trajectory of the object when it is transported along the first direction is parallel to the movement trajectory of the object when it is transported along the third direction; the first limit group 51 and the second limit group 52 in the centering unit 5 are close to each other in the direction toward each other, and the movement trajectory of the first limit group 51 and the second limit group 52 are both parallel to the fourth direction, the fourth direction is perpendicular to the first direction, and the second direction is parallel to the fourth direction.

[0082] like Figure 8 and Fig.10 As shown, in some embodiments, the first conveying unit 21 includes a first mounting frame 211 and a first conveying module 212 (the first conveying module 212 may include a first flexible transmission member 2122 and a plurality of rollers 2123 described below), and the first conveying module 212 is mounted on the first mounting frame 211. Fig.11 and Fig.12As shown, the second transmission unit 22 includes a second mounting frame 221 and a second transmission module 222 (the second transmission module 222 may include a plurality of driving wheels 2222, a plurality of driven wheels 2223 and a plurality of second flexible transmission members 2224 as described later), and the second transmission module 222 is mounted on the second mounting frame 221. Figure 8 The first mounting frame 211 and the second mounting frame 221 slide up and down through the second guide structure 32. That is, through the second guide structure 32, the second mounting frame 221 can slide up and down relative to the first mounting frame 211, so that the second conveying module 222 can slide up and down relative to the first conveying module 212. The second guide structure 32 includes a second guide hole 321 and a second guide column 322. The second guide hole 321 and the second guide column 322 slide and cooperate, which is simple and reliable, and convenient to set and assemble, which is conducive to the second conveying unit 22 sliding more smoothly and stably relative to the first conveying unit 21. There are multiple second guide structures 32, and at least two of the multiple second guide structures 32 are arranged at the corner positions of the second mounting frame 221. By setting multiple second guide structures 32, it is conducive to improving the stability and reliability of the guide. And / or, the first lifting unit 41 is installed on the first mounting frame 211, and the first lifting unit 41 is arranged relative to the first driver 2121 of the first conveying module 212. Such an arrangement can improve the utilization rate of the first mounting frame 211 and make the structure more compact.

[0083] like Fig.11 As shown, in a specific example, the second guide hole 321 is disposed on the second mounting frame 221 of the second conveying unit 22; Fig.13 As shown, the second guide post 322 is disposed on the first mounting frame 211 of the first conveying unit 21. Of course, the second guide hole 321 can be disposed on the first mounting frame 211 of the first conveying unit 21, and the second guide post 322 can be disposed on the second mounting frame 221 of the second conveying unit 22. A first stopper 323 is disposed at one end of the second guide post 322, which helps to prevent the second guide post 322 from being disengaged from the second guide hole 321, thereby improving reliability.

[0084] like Figure 8-Figure 10 As shown, in some embodiments, the first conveying unit 21 includes a first mounting frame 211, a first driver 2121, a first flexible transmission member 2122 and a plurality of rollers 2123, the plurality of rollers 2123 are arranged at intervals along the conveying direction of the first conveying unit 21, and the axial ends of each roller 2123 are rotatably arranged on the first mounting frame 211, and the first driver 2121 drives the plurality of rollers 2123 to rotate synchronously through the first flexible transmission member 2122. Fig.13 and Fig.14As shown, the second conveying unit 22 includes a second mounting frame 221, a second driver 2221, a plurality of driving wheels 2222, a plurality of driven wheels 2223 and a plurality of second flexible transmission members 2224, each second flexible transmission member 2224 corresponds to a driving wheel 2222 and at least one driven wheel 2223, the second driver 2221 drives the plurality of second flexible transmission members 2224 to rotate synchronously through the plurality of driving wheels 2222, and each second flexible transmission member 2224 is arranged between two adjacent rollers 2123. The second flexible transmission member 2224 is arranged between the two rollers 2123, the second driver 2221 drives the driving wheel 2222 to rotate, the driving wheel 2222 and the driven wheel 2223 are connected through the second flexible transmission member 2224, the driving wheel 2222 drives the driven wheel 2223 to rotate, and the second flexible transmission member 2224 can also convey items to a designated position, the second flexible transmission member 2224 here can transmit power to the driven wheel 2223, the second flexible transmission member 2224 at any position can transmit power, the second flexible transmission member 2224 is continuous without gaps, and the second flexible transmission member 2224 can convey items. For example, the second flexible transmission member 2224 can be a belt, and the friction force of the belt is used to drive the items to move. The second transmission unit 22 uses the second flexible transmission member 2224 to transmit items, which has a simple structure and is stable and reliable in conveying items.

[0085] like Figure 13-14 As shown, in some embodiments, the second conveying unit 22 satisfies at least one of the following conditions: Condition A1, the diameter of the driving wheel 2222 is greater than the diameter of the driven wheel 2223, and the rotation speed of the driven wheel 2223 is greater than the rotation speed of the driving wheel 2222, which can improve the efficiency and speed of object conveying; Condition A2, the driving wheel 2222 is arranged below the driven wheel 2223 at intervals, and the two driven wheels 2223 corresponding to the second flexible transmission member 2224 are arranged at opposite sides of the driving wheel 2222 along the conveying direction of the second conveying unit 22, and the second conveying unit 22 further includes a plurality of tensioning wheels 22 25. Each second flexible transmission member 2224 corresponds to at least one tensioning wheel 2225. The tensioning wheel 2225 is arranged on the outer side of the second flexible transmission member 2224. In the up and down directions and the transmission direction of the second transmission unit 22, the tensioning wheel 2225 is arranged between the driving wheel 2222 and the corresponding driven wheel 2223. The relative position between the driven wheel 2223 and the driving wheel 2222 is fixed. The tensioning wheel 2225 can tension the second flexible transmission member 2224, so that the second flexible transmission member 2224 is pressed against the driving wheel 2222 and the driven wheel 2223, thereby improving the transmission efficiency and reliability.

[0086] like Figure 13-14As shown, in some embodiments, the second transmission unit 22 satisfies condition A2, and the position of at least one tensioning wheel 2225 corresponding to the second flexible transmission member 2224 is adjustable in a preset direction, and the preset direction is parallel to the transmission direction of the second transmission unit 22, or the preset direction is the up-down direction, or the preset direction is inclined relative to the up-down direction and the transmission direction of the second transmission unit 22. The second flexible transmission member 2224 is stretched and loosened during use, and the tensioning wheel 2225 can tension the second flexible transmission member 2224 to ensure that the second flexible transmission member 2224 is normally transmitted without slipping. The tensioning wheel 2225 can be adjusted according to the specific situation of the aging of the second flexible transmission member 2224 to improve the transmission reliability of the second flexible transmission member 2224.

[0087] like Figure 13-14 As shown, in some embodiments, the plurality of tensioning wheels 2225 corresponding to each second flexible transmission member 2224 include a first tensioning wheel 22251 and a second tensioning wheel 22252, and the first tensioning wheel 22251 and the second tensioning wheel 22252 are respectively arranged on opposite sides of the driving wheel 2222. By arranging the plurality of tensioning wheels 2225 on different sides of the driving wheel 2222, the second flexible transmission member 2224 can be tensioned from different positions, further improving the transmission reliability of the second flexible transmission member 2224. The second driver 2221 is arranged at intervals on one side of the driving wheel 2222 in the transmission direction of the second transmission unit 22, that is, the second driver 2221 is arranged at intervals from the driving wheel 2222, and the second driver 2221 is arranged at one side of the driving wheel 2222 in the transmission direction of the second transmission unit 22. The second driver 2221 can be arranged below the second transmission unit 22, making full use of the height space of the second transmission unit 22, so that the structure of the second transmission unit 22 is more compact.

[0088] like Figure 13-14 As shown, in a specific example, the second mounting frame 221 is provided with a second avoidance portion and a third avoidance portion, the second avoidance portion can avoid the driving wheel 2222, and the driving wheel 2222 can be close to the second mounting frame 221, which is conducive to reducing the gap and distance between the driving wheel 2222 and the driven wheel 2223, thereby saving the material of the second flexible transmission member 2224; the third avoidance portion can avoid the second driver 2221, and the second driver 2221 is connected to the driving wheel 2222 through a tension belt. In summary, on the basis of ensuring the structural strength of the second mounting frame 221, the structure of the second transmission unit 22 is more compact.

[0089] like Figure 8-Figure 9As shown, in some embodiments, in the conveying direction of the second conveying unit 22, at least one of the two ends of the second conveying unit 22 extends out of the first conveying unit 21. For example, both ends of the second conveying unit 22 extend out of the first conveying unit 21, so that the article can be conveyed from any end of the two ends of the second conveying unit 22 in its conveying direction to the second conveying unit 22; for another example, one end of the second conveying unit 22 in its conveying direction extends out of the first conveying unit 21, and the article can be conveyed from the above-mentioned one end of the second conveying unit 22 to the first conveying unit 21. It can be seen that the part of the above-mentioned at least one end of the second conveying unit 22 extending out of the first conveying unit 21 is conducive to the second conveying unit 22 to better receive the article, reduce the influence of the first conveying unit 21 on the second conveying unit 22 receiving the article, and improve the reliability of the transmission.

[0090] In the related art, articles can be conveyed from other conveyor belts along the second direction to the second conveying unit. Under the restriction of components such as the frame and the shell, there is a certain distance between other conveyor belts and the conveying unit, and a gap is formed between other conveyor belts and the conveying unit. When passing through the gap, the placement of the articles may change, or even fall from the gap and be damaged. In the present application, the second conveying unit 22 extends out of the first conveying unit 21 to receive articles, which is conducive to smoother conveying of articles and improving the reliability of article conveying; in addition, the second conveying unit 22 is embedded in the first conveying unit 21, so that the second conveying unit 22 is not likely to affect the reliability of the first conveying unit 21 in receiving articles, which is convenient for the first conveying unit 21 to stably receive articles at either end of its conveying direction.

[0091] like Fig.14 As shown, for example, the end of the second flexible transmission member 2224 in the transmission direction away from the second driver 2221 extends out of the first conveying unit 21. The end of the second flexible transmission member 2224 extending out of the first conveying unit 21 receives the article, and at this time, the center of gravity of the second conveying unit 22 is offset to the end receiving the article. Since the second driver 2221 is arranged at the lower side of the other end of the second flexible transmission member 2224, the center of gravity of the second conveying unit 22 can be balanced, and the position arrangement is more reasonable.

[0092] In some embodiments, at least one end of the second conveying unit 22 extends out of the machine body 1. For example, both ends of the second conveying unit 22 extend out of the machine body 1; for another example, one end of the second conveying unit 22 extends out of the machine body 1. The second conveying unit 22 can convey items outside the machine body 1, that is, the portion of the second conveying unit 22 extending out of the machine body 1 can receive and convey the items, and during the transmission of the items, the portion of the second conveying unit 22 extending out of the machine body 1 is staggered, which is conducive to avoiding interference between the second conveying unit 22 and the machine body 1 and improving the stability of the item transmission.

[0093] like Figure 8-Figure 14 As shown, in some embodiments, the first conveying unit 21 includes a first mounting frame 211, a first driver 2121, a first flexible transmission member 2122 and a plurality of rollers 2123. The plurality of rollers 2123 are arranged at intervals along the conveying direction of the first conveying unit 21, and the two axial ends of each roller 2123 are rotatably arranged on the first mounting frame 211. The first driver 2121 is arranged on the same side of the axial direction of the plurality of rollers 2123, and the first driver 2121 drives the plurality of rollers 2123 to rotate synchronously. In the conveying direction of the second conveying unit 22, one end of the second conveying unit 22 is away from the first flexible transmission member 2122, and the other end of the second conveying unit 22 is close to the first flexible transmission member 2122, wherein one end of the second conveying unit 22 extends out of the first conveying unit 21, and the other end of the second conveying unit 22 does not extend out of the first conveying unit 21, so that the extended end of the second conveying unit 22 is not easy to interfere with the first flexible transmission member 2122. The first driver 2121 drives the plurality of rollers 2123 to rotate, and the plurality of rollers 2123 roll relative to the first mounting frame 211 and convey the articles along the conveying direction of the first conveying unit 21. The specifications of the plurality of rollers 2123 are consistent, and the articles are more stable during the conveying process, so that the articles are conveyed by the rollers 2123, which is conducive to improving the stability and reliability of the article conveying. The first driver 2121 is arranged on the same side of the axial direction of the plurality of rollers 2123, which can simplify the structure and arrangement of the first flexible transmission member 2122, making the structure more compact and reasonable.

[0094] like Figure 8-Figure 14 As shown, in combination with the above-mentioned specific embodiments, there is an avoidance space between the multiple rollers 2123 through which the second conveying unit 22 can pass, so that the second conveying unit 22 can be set in the avoidance space between the multiple rollers 2123, and under the lifting of the first lifting unit 41, the second conveying unit 22 can be lifted and lowered relative to the first conveying unit 21 and pass through the avoidance space.

[0095] like Fig.10 As shown, in a specific example, the first mounting frame 211 includes a first mounting portion and a second mounting portion, and one axial side of the plurality of rollers 2123 is rotatably disposed on the first mounting portion, and the other axial side of the plurality of rollers 2123 is rotatably disposed on the second mounting portion. The first driver 2121 and the first flexible transmission member 2122 are disposed on one side of the first mounting portion of the plurality of rollers 2123, and the second conveying unit 22 can extend from one side of the second mounting portion of the plurality of rollers 2123 to the second mounting portion. Since the first flexible transmission member 2122 needs to be arranged on the first mounting portion, it is difficult for the second conveying unit 22 to extend from the first mounting portion, and a first avoidance portion 2111 is provided on the second mounting portion to avoid the second conveying unit 22 and extend the second conveying unit 22 from the first avoidance portion 2111 to the first conveying unit 21.

[0096] In some embodiments not shown in the figures, the roller 2123 in the first conveying unit 21 adopts an electric roller structure, and a motor for driving the electric roller to rotate is arranged inside the electric roller. The multiple electric rollers can rotate independently relative to each other, and the setting of the first flexible transmission member 2122 is cancelled. Therefore, the second mounting parts can be adopted at both axial ends of the electric roller, and both ends of the second conveying unit 22 can extend out of the first conveying unit 21.

[0097] Combination Fig.12 and Fig.13 For example, the first lifting unit 41 includes a first lifting ramp 411, a first lifting motor 412 and a lifting wheel 413. The first lifting motor 412 is a linear motor and includes a stator unit 4121 and a mover unit 4122, and the mover unit 4122 can make a linear motion relative to the stator unit 4121, wherein one end of the mover unit 4122 is connected to the first lifting ramp 411, and the lifting wheel 413 is fixedly connected to the second mounting frame 221, and the lifting wheel 413 abuts on the slope of the first lifting ramp 411. When the first lifting unit 41 needs to lift the second conveying unit 2222, the mover unit 4122 moves and drives the first lifting ramp 411 to move, and the top of the first lifting ramp 411 gradually approaches the lifting wheel 413. When the second conveying unit 2222 is lifted to a preset position, the lifting wheel 413 abuts against one end of the first lifting ramp 411 near the top of the slope.

[0098] For example, the second flexible transmission member 2224 extends out of the first conveying unit 21 at one end thereof in the conveying direction away from the second driver 2221. The end of the second flexible transmission member 2224 extending out of the first conveying unit 21 receives the article, and at this time, the center of gravity of the second conveying unit 22 is offset toward the end receiving the article. Since the second driver 2221 is disposed at the lower side of the other end of the second flexible transmission member 2224, the center of gravity of the second conveying unit 22 can be balanced, and the position arrangement is more reasonable.

[0099] like Fig.16 As shown, the fourth conveying unit 24 can directly convey the article to the first conveying unit 21 in the first state. The first conveying unit 21 rotates under the action of the rotating unit 6, so that the conveying direction of the first conveying unit 21, that is, the first direction, is parallel to the conveying direction of the fourth conveying unit 24. In the first state, the first direction is parallel to the fourth direction, and the conveying surface of the first conveying unit 21 is flush with the conveying surface of the fourth conveying unit 24.
