Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom cover conveying device of the can body includes: a first conveying structure 10, a cover storage rack 20, a second conveying structure 30, a first detection device 41, a second detection device 42, a third detection device 43 and a controller 50. The first conveying structure 10 is used to transport the cover body. The cover storage rack 20 has a conveying channel 21, and the upper end of the cover storage rack 20 is connected to the first conveying structure 10. The second conveying structure 30 is connected to the lower end of the cover storage rack 20. The first detection device 41, the second detection device 42 and the third detection device 43 are arranged on the cover storage rack 20 at intervals, and are all used to detect the cover body. The first detection device 41 is located below the second detection device 42, and the second detection device 42 is located between the first detection device 41 and the third detection device 43. The controller 50 is electrically connected to the first detection device 41, the second detection device 42 and the third detection device 43 and controls the start and stop of the first conveying structure 10 and the start and stop of the second conveying structure 30.

[0028] By applying the technical solution of this embodiment, the cap body enters the conveying channel 21 of the cap storage rack 20 from the first conveying structure 10, and then moves from the conveying channel 21 to the second conveying structure 30. The first detection device 41, the second detection device 42 and the third detection device 43 are arranged on the cap storage rack 20, and are used to detect the cap body. The second detection device 42 is located between the first detection device 41 and the third detection device 43, and the first detection device 41 is located below the second detection device 42. The controller 50 is connected to the first detection device 41, the second detection device 42 and the third detection device 43, and controls the start and stop of the first conveying structure 10 and the second conveying structure 30. Through the above-mentioned setting, when the third detection device 43 detects the cap body, the controller 50 controls the first conveying structure 10 to stop, and the second conveying structure 30 is running at this time, and the cap body in the conveying channel 21 is transported to the second conveying structure 30. When the second detection device 42 does not detect the cap body, the controller 50 controls the first conveying structure 10 to start. When the first detection device 41 does not detect the cap, the controller 50 controls the second conveying structure 30 to stop, and the first conveying structure 10 continues to transport the cap to the conveying channel 21. When the second detection device 42 detects the cap, the controller 50 controls the second conveying structure 30 to start, which can prevent too many caps in the cap storage rack 20, and can also prevent too few caps in the cap storage rack 20, thereby ensuring the processing efficiency of the can body and avoiding poor can body sealing. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that there are too many bottom caps in the cap storage rack and overflow from the cap storage rack, which will affect the processing efficiency of the can body.

[0029] It should be noted that when the first conveying structure 10 suddenly pauses, the second conveying structure 30 will not stop, that is, it will continue to run until there is no cover body in the cover storage rack 20. When the first conveying structure 10 resumes normal operation, due to the increase in the height difference of the conveying channel 21, the cover body is easily affected by the air resistance during the falling process, which may cause the cover body to reverse or deviate. The technical solution of this embodiment is provided with a first detection device 41, a second detection device 42 and a third detection device 43, and can control the start and stop of the first conveying structure 10 and the second conveying structure 30, which can avoid the cover body from moving too far in the cover storage rack 20, and thus can effectively avoid the problem of cover body reversal or cover body deviation.

[0030] like Figures 2 to 4 As shown, in this embodiment, the distance between the first detection device 41 and the second detection device 42 is greater than or equal to the distance between the second detection device 42 and the third detection device 43. The above arrangement can keep more caps in the conveying channel 21, so that no caps are transported to the second conveying structure 30.

[0031] like Figures 2 to 4As shown, in this embodiment, the distance a between the first detection device 41 and the bottom of the storage cover rack 20 and the distance b between the first detection device 41 and the third detection device 43 satisfy: 0.25≤a / b≤0.5. The above arrangement can make the number of covers in the storage cover rack 20 more reasonable, preferably, a / b=0.35.

[0032] like Figures 2 to 4 As shown, in this embodiment, the distance b between the first detection device 41 and the third detection device 43 is greater than or equal to 900 mm.

The arrangement of the outer frame 22 and the inner frame 23 can make the structural strength of the storage cover rack 20 better. Specifically, the inner frame 23 includes a plurality of columns 231, so that the structure of the inner frame 23 is simple, and the cover body can be limited, so that the position stability of the cover body is better.

[0034] like Figures 2 to 4 As shown, in this embodiment, the outer frame 22 includes a frame body 221 and a plurality of beams 222 disposed on the frame body 221, and the first detection device 41, the second detection device 42, and the third detection device 43 are respectively disposed on the plurality of beams 222. The provision of the plurality of beams can improve the structural strength of the frame body, and the beams can provide a fixed position for the first detection device 41, the second detection device 42, and the third detection device 43, thereby making the positions of the first detection device 41, the second detection device 42, and the third detection device 43 more stable.

[0035] Specifically, in this embodiment, the first detection device 41 , the second detection device 42 and the third detection device 43 are all infrared detection structures.

[0036] like Figures 2 to 4 As shown, in this embodiment, the first conveying structure 10 includes a frame 11 and a conveyor belt 12 arranged on the frame 11, and a magnetic member is arranged in the frame 11. The arrangement of the magnetic member can absorb the cover body, thereby making the cover body move stably on the conveyor belt 12.

[0037] like Figures 2 to 4As shown, in this embodiment, the first conveying structure 10 further includes a stopper 13, which is arranged at the end of the conveyor belt 12 and located at the side of the cap storage rack 20, and the stopper 13 cooperates with the cap body to stop the cap body so that the cap body falls into the conveying channel 21. The setting of the stopper 13 can stop the cap body, and the cap body can fall into the conveying channel 21 after being stopped by the stopper 13.

[0038] Specifically, the stopper 13 is a stop block.

[0039] like Figure 5 As shown, in this embodiment, the controller 50 includes a PLC, the input end of the first detection device 41 is connected to the first input end of the PLC, the input end of the second detection device 42 is connected to the second input end of the PLC, and the input end of the third detection device 43 is connected to the third input end of the PLC. The control stability of the above-mentioned PLC is good.

[0040] like Figure 5 As shown, in this embodiment, the first output end of the PLC is connected to the first conveying structure 10, the second output end of the PLC is connected to both the first conveying structure 10 and the second conveying structure 30, and the third output end of the PLC is connected to the second conveying structure 30. The above arrangement can realize the control of the start and stop of the first conveying structure 10 and the second conveying structure 30.

[0041] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0042] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0043] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
