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

[0028] The cap conveying device of the embodiment is a waterfall cap sorting machine, which uses the principle of the center of gravity of the cap to screen. Since the conveyed cap 1 is very thin, the difference between the forward cap 2 and the reverse cap 3 is very small, and during the lifting process, part of the reverse cap 3 cannot fall off, the reverse cap 3 is lifted and conveyed to the cap pressing machine, causing the cap pressing machine to be stuck or the cap to be unable to fall off, causing production to stop.

[0029] As shown in Figure 1 The cap conveying device of the embodiment includes a conveying structure 10, a rejection structure 20, a first detection structure, and a controller. The conveying structure 10 includes a conveying member 11 and a plurality of limiting rods 12. The conveying member 11 can move the cap 1 along the vertical direction. The plurality of limiting rods 12 are arranged on the conveying member 11 along the circumferential direction of the conveying member 11. Each limiting rod 12 extends along the width direction of the conveying member 11. Any two adjacent limiting rods 12 and the conveying member 11 form a containing space for containing the cap 1. The rejection structure 20 includes a first mounting member 21, a first driving member 22, and a rejection assembly 23. The first mounting member 21 is arranged on the conveying structure 10. The first driving member 22 is arranged on the first mounting member 21 and is drivingly connected with the rejection assembly 23 to move the rejection assembly 23 towards or away from the conveying member 11. The first detection structure is arranged on the conveying structure 10 to detect the position of the limiting rod 12. The controller is signal connected with the first detection structure and the first driving member 22 to move the rejection assembly 23 by the first driving member 22.

[0030] The technical scheme is applied to the cover conveying device, which comprises a conveying structure 10, a removing structure 20, a first detection structure and a controller. The conveying structure 10 comprises a conveying member 11, which can drive the cover 1 to move along the vertical direction. The conveying structure 10 further comprises a plurality of limiting rods 12 arranged on the conveying member 11, the plurality of limiting rods 12 are arranged at intervals along the circumferential direction of the conveying member 11, and each limiting rod 12 extends along the width direction of the conveying member 11. Any two adjacent limiting rods 12 and the conveying member 11 form an accommodation space, which is used to accommodate the cover 1. The removing structure 20 comprises a first mounting member 21 arranged on the conveying structure 10 and a first driving member 22 arranged on the first mounting member 21. The removing structure 20 further comprises a removing assembly 23, which is drivingly connected with the first driving member 22, so that the removing assembly 23 moves towards the conveying member 11 or away from the conveying member 11. The first detection structure is arranged on the conveying structure 10, and is used to detect whether the limiting rod 12 passes through the first detection structure. The controller is signal connected with the first detection structure and the first driving member 22, and controls the first driving member 22 to drive the removing assembly 23 to move. Through the above arrangement, the cover 1 can enter the accommodation space and move along the vertical direction under the driving of the limiting rod 12. When the first detection structure detects that the limiting rod 12 passes through the first detection structure, the controller controls the first driving member 22 to operate, the first driving member 22 drives the removing assembly 23 to move towards the conveying member 11, and then the removing assembly 23 can contact the reverse cover 3. After the removing assembly 23 contacts the reverse cover 3, the removing assembly 23 drives the reverse cover 3 to move away from the conveying member 11, so that the reverse cover 3 can be removed, and the reverse cover 3 is prevented from being conveyed to the capping machine. Therefore, the technical scheme of the embodiment effectively solves the problem that the reverse cover 3 may enter the capping machine in the related art.

[0031] The first mounting member 21 is a first mounting plate.

[0032] It should be noted that the first driving member 22 can drive the removing assembly 23 to reciprocate, that is, after the first driving member 22 drives the removing assembly 23 to move towards the conveying member 11 by a preset distance, the first driving member 22 drives the removing assembly 23 to move away from the conveying member 11 by a preset distance, regardless of whether the removing assembly 23 has the reverse cover 3 or not.

[0033] The conveying structure 10 further comprises a rack, and the conveying member 11 and the first mounting member 21 are arranged on the rack. The conveying member 11 is a conveying plate chain. In other embodiments, the conveying member 11 can be a conveying belt.

[0034] The preset included angle is between 75° and 85°, and can be 75°, 77°, 80°, 83° or 85°.

[0035] The ejecting assembly 23 has an ejecting position and an avoiding position. When the ejecting assembly 23 is in the ejecting position, the distance between the ejecting assembly 23 and the conveying member 11 is a first distance. When the ejecting assembly 23 is in the avoiding position, the distance between the ejecting assembly 23 and the conveying member 11 is a second distance. The first distance is smaller than the second distance. When the ejecting assembly is in the ejecting position, the ejecting assembly 23 can take the reverse cover body 3 out of the accommodating space. When the ejecting assembly 23 is in the avoiding position, the ejecting assembly 23 has a space with the cover body 1 in the accommodating space.

[0036] The first driving member 22 is a cylinder. The first driving member 22 includes a plurality of telescopic rods arranged at intervals.

[0037] After the cover body conveying device moves the cover body 1 along the vertical direction, the cover body 1 enters the capping machine.

[0038] As shown in the drawings, Figures 1 to 3 In the embodiment, the ejecting assembly 23 includes a second mounting member 231 and a plurality of suction accessories 232. The second mounting member 231 is connected with the telescopic rod of the first driving member 22, and extends along the width direction of the conveying member 11. The plurality of suction accessories 232 are arranged at intervals on the second mounting member 231. The telescopic rod of the first driving member 22 can drive the second mounting member 231 to move, and then the second mounting member 231 can drive the plurality of suction accessories 232 to move. Thus, when the reverse cover body 3 needs to be ejected, the telescopic rod of the first driving member 22 can drive the second mounting member 231 to move towards the conveying member 11 or away from the conveying member 11, and then drive the plurality of suction accessories 232 to move towards the conveying member 11 or away from the conveying member 11. Thus, when the reverse cover body 3 exists in the accommodating space, the suction accessories 232 can take the reverse cover body 3 out of the accommodating space.

[0039] The second mounting member 231 is a second mounting plate.

[0040] In the embodiment, the suction accessories 232 are suction cups. The vacuum adsorption principle is used to realize that the suction accessories 232 take the reverse cover body 3 out of the accommodating space.

[0041] The number of the suction accessories 232 is determined according to the number of the cover bodies 1 that can be accommodated along the width direction of the conveying member 11.

[0042] In other embodiments, the suction accessories 232 can also be magnets, and correspondingly, the material of the cover body 1 is metal.

[0043] As shown in the drawings, Figure 2 and Figure 5As shown, in the embodiment, the plurality of suction accessories 232 are arranged at equal intervals along the width direction of the conveying member 11. The diameters of each cover body 1 are the same, so that the plurality of suction accessories 232 are arranged in one-to-one correspondence with the plurality of cover bodies 1, and when the reverse cover body 3 exists in the accommodation space, the suction accessory 232 can accurately contact the reverse cover body 3 and move the reverse cover body 3 out of the accommodation space.

[0044] As shown in the drawings, Figure 5 and Figure 6 As shown, in the embodiment, the cover conveying device further comprises a suction structure and an inflation structure, the suction accessory 232 is provided with a vent hole, the vent hole is connected with the suction structure and the inflation structure, and the suction accessory 232 has a suction cover state and a separation state. When the suction accessory 232 is switched from the separation state to the suction cover state, the suction structure is communicated with the vent hole, and when the suction accessory 232 is switched from the suction cover state to the separation state, the inflation structure is communicated with the vent hole. When the suction accessory 232 moves towards the conveying member 11, the suction structure is communicated with the vent hole, so that the suction accessory 232 can stably contact the reverse cover body 3, and the suction accessory 232 can drive the reverse cover body 3 to move. After the suction accessory 232 drives the reverse cover body 3 to move away from the accommodation space, the suction structure is disconnected from the vent hole, the inflation structure is connected with the vent hole, and then under the action of the airflow, the reverse cover body 3 can be separated from the suction accessory 232.

[0045] The vent hole is arranged on the suction disc.

[0046] The suction structure comprises a vacuum generator. The vacuum generator is provided with a generator exhaust silencer, which can reduce noise.

[0047] As shown in the drawings, Figure 2 As shown, in the embodiment, the rejection assembly 23 comprises a gas distribution valve 233, the gas distribution valve 233 is provided with a first communication hole, a second communication hole and a plurality of third communication holes, the first communication hole is communicated with the suction structure, the first communication hole is communicated with the plurality of third communication holes, the second communication hole is communicated with the inflation structure, the second communication hole is communicated with the plurality of third communication holes, and the plurality of third communication holes are arranged in one-to-one correspondence with the plurality of suction accessories 232. When the suction structure is communicated with the first communication hole, the airflow can be sucked into the suction accessory 232, and then the airflow can flow into the suction structure through the third communication hole and the first communication hole in turn. When the inflation structure is communicated with the second communication hole, the airflow can flow into the gas distribution valve 233 from the inflation structure, and then flow out through the plurality of third communication holes, and then flow into the suction accessory 232.

[0048] The suction structure further comprises a vacuum degree adjusting valve arranged between the gas distribution valve 233 and the vacuum generator, which can adjust the vacuum flow to ensure that the air pressure reaches the required suction of the reverse cover body 3.

[0049] The first air pressure adjusting valve is arranged between the second communication hole and the air charging structure to adjust the air pressure, so as to avoid that the air pressure of the air blown out from the suction accessory 232 is too large, the reverse cover body 3 is blown back to the conveying member, the air pressure is too small, the reverse cover body 3 cannot be separated from the suction accessory 232, and is always adsorbed on the suction accessory 232, thereby affecting the subsequent operation of the removing assembly 23.

[0050] As shown in Figure 2 and Figure 4 In the embodiment, the cover conveying device further comprises a second detection structure, the second detection structure is signal connected with the controller, and the second detection structure is used to detect the position of the telescopic rod of the first driving member 22, so that the controller controls the suction accessory 232 to switch from the cover suction state to the separation state. After the telescopic rod of the first driving member 22 drives the plurality of suction accessories 232 to move towards the direction away from the conveying member 11, the second detection structure can detect the position of the telescopic rod of the first driving member 22, so that the controller can judge that the reverse cover body 3 has left the containing space according to the detection signal of the second detection structure, and then the controller can control the air charging structure to communicate with the second communication hole to blow air into the suction accessory 232, so that the cover body 1 is separated from the suction accessory 232.

[0051] When the removing assembly 23 moves from the removing position to the avoiding position, the air charging structure inputs air flow into the suction accessory 232 through the second communication hole, that is, the suction accessory 232 switches from the cover suction state to the separation state.

[0052] As shown in Figure 2 and Figure 3 In the embodiment, the cover conveying device further comprises a blowing structure 30, the blowing structure 30 is arranged on the side of the conveying member 11 and outputs air towards the other side of the width direction of the conveying member 11. The blowing structure 30 can blow air to form air flow, and the air flow can apply a pushing force to the cover body 1, so that the cover body 1 moves towards the side of the conveying member 11, the cover body 1 in the containing space corresponds to the suction accessory 232, and then the removing assembly 23 can adsorb all the reverse cover bodies 3 in the containing space.

[0053] In other embodiments, the blowing structure 30 can not be arranged, the length direction of the limiting rod 12 is arranged to have a preset angle with the width direction of the conveying member 11, so that the cover body 1 moves towards the side of the conveying member 11 under the action of its own gravity, and the plurality of cover bodies 1 are arranged in close contact. At the same time, the plurality of suction accessories 232 are also arranged to be spaced apart along the length direction of the limiting rod 12, so as to facilitate the suction accessory 232 to adsorb the reverse cover body 3.

[0054] As shown in Figure 3As shown, in this embodiment, the air blowing structure 30 includes a mounting rod 31 disposed on the conveying structure 10. The mounting rod 31 extends along the conveying direction of the conveying member 11, and an air outlet 311 is provided on the mounting rod 31. Gas can be blown out through the air outlet 311.

[0055] It should be noted that the mounting rod 31 is provided with a fourth connecting hole, which is connected to the inflation structure.

[0056] Mounting rod 31 is mounted on the frame.

[0057] like Figure 1 As shown, in this embodiment, the cover conveying device further includes a baffle 40 disposed on the side of the mounting rod 31 away from the conveying component 11, and a preset interval is provided between the baffle 40 and the limiting rod 12. The gas flowing out of the vent 311 can exert an impact force on the cover 1. The baffle 40 prevents the cover 1 from being blown off the receiving space by the airflow and also prevents multiple covers 1 from overlapping under the action of the airflow. The preset interval between the baffle 40 and the limiting rod 12 ensures the normal operation of the conveying component 11 and the limiting rod 12.

[0058] The preset interval is between 2mm and 4mm, specifically, it can be 2mm, 2.5mm, 3mm, 3.5mm, or 4mm. In this embodiment, the preset interval is 3mm.

[0059] A second air pressure regulating valve is also provided between the fourth connecting hole and the inflation structure, which can regulate the air pressure to prevent the cover 1 from moving toward the side of the conveyor 11 when the air pressure is too low, and to prevent the airflow from blowing the cover 1 out of the conveyor 11 and the baffle 40 when the air pressure is too high.

[0060] It should be noted that the baffle 40 is transparent, making it easy to observe the cover 1.

[0061] like Figure 1 As shown, in this embodiment, the rejection structure 20 further includes a receiving structure 50 disposed below the conveying structure 10. At least a portion of the conveying structure 10 is located within the receiving structure 50, which is used to receive the cover 1. The receiving structure 50 can hold the cover 1, facilitating the conveying structure 10 to move the cover 1 vertically. After the reverse cover 3 separates from the adsorption member, the reverse cover 3 falls into the receiving structure, facilitating the conveying structure 10 to move it again.
