The cap sorting device sorts the messy bottle caps into relatively fixed positions and consistent orientations, and then sends them to the production line so that the production line can install the bottle caps on the bottles. At present, visual inspection is usually used to detect bottle caps with unqualified orientations, and then intermittent control of robots or nozzles will remove the unqualified bottle caps. This method has a complex removal process and relatively high costs, and visual inspection is difficult to detect.

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] like Figures 1 to 7As shown, the cap sorting device of this embodiment comprises a rotating bin 1 and a cap sorting channel 2. The rotating bin 1 comprises a rotating bin body 11 and a cap placing plate 12 arranged on the top periphery of the rotating bin body 11. One end of the cap sorting channel 2 is connected to the cap placing plate 12 for the qualified bottle caps 100 to enter, and the other end of the cap sorting channel 2 extends to the outside of the rotating bin 1 for outputting the bottle caps 100.

[0042] A defective bottle cap returning mechanism 3 is provided on one side of the cover plate 12, and the defective bottle cap returning mechanism 3 is used to allow the qualified bottle caps 100 to pass through and blow the defective bottle caps 100 back into the rotating bin body 11;

[0043] The unqualified bottle cap returning mechanism 3 includes a cap blocking member 31 and an air blowing member 32. The air blowing member 32 is used to blow the bottle caps 100 on the cover plate 12 into the rotating warehouse body 11. The cap blocking member 31 is used to push the unqualified bottle caps 100 toward the rotating warehouse body 11 and block the qualified bottle caps 100 to prevent them from being blown into the rotating warehouse body 11 by the air blowing member 32.

[0044] In this embodiment, it is applicable to a Fig. 9The illustrated special-shaped bottle cap 100 (such as a gourd-shaped cap) comprises a cap column 101 and a cap bottom 102 disposed at the bottom of the cap column 101, and the cap bottom 102 protrudes toward the peripheral side of the cap column 101. The special-shaped bottle cap 100 is used as an example to illustrate the cap sorting process. The bottle cap 100 has three states on the cap placement plate 12, namely, a normal cap, that is, the cap bottom 102 faces downward, which is a qualified direction; a reverse cap, that is, the cap bottom 102 faces upward, which is a failed direction; and an inverted cap, that is, the bottle cap 100 is tilted, which is a failed direction. The cap sorting device of the present embodiment, when sorting caps, places a plurality of bottle caps 100 to be sorted into the rotating bin body 11, the rotating bin 1 rotates, and the bottle caps 100 gradually move onto the cap placing plate 12 under the action of centrifugal force, and when the bottle caps 100 on the cap placing plate 12 are rotated and transported to the unqualified bottle cap returning mechanism 3 with the cap placing plate 12, the unqualified bottle caps 100 are pushed and blown into the rotating bin body 11 under the pushing action of the cap blocking member 31 and / or the blowing action of the air blowing member 32, and the upper surface of the edge of one side of the cap bottom 102 of the qualified bottle caps 100 is not affected by the blowing of the air blowing member 32 under the blocking action of the cap blocking member 31, and continue to be rotated and transported by the cap placing plate 12, enter the cap sorting channel 2, and output the qualified bottle caps 100 outward. In the cap sorting device of the present embodiment, the unqualified bottle cap returning mechanism 3 is composed of a cap blocking member 31 and an air blowing member 32, and has a simple structure. The unqualified bottle caps 100 are rejected by the unqualified bottle cap returning mechanism 3 and returned to the rotating warehouse body 11 to be re-capped without adjusting the direction on the cover plate 12, and the cap sorting efficiency is high; the unqualified bottle caps 100 are rejected and returned to the rotating warehouse body 11 by the pushing action of the cap blocking member 31 and / or the blowing action of the air blowing member 32, and the returning process of the unqualified bottle caps 100 is simple and low in cost; the unqualified bottle caps 100 are prevented from being missed and rejected by the pushing and / or blowing action, and the missed rejection rate is low. Because the cap blocking member 31 can also limit and guide the qualified bottle caps 100 to prevent them from being blown into the rotating warehouse body 11 by the air blowing member 32, the qualified bottle caps 100 are prevented from being rejected, the wrong rejection rate is low, and the qualified cap sorting rate is high.

[0045] Furthermore, if Figure 2As shown, in this embodiment, the cap-blocking member 31 has a protruding portion, and there is a height difference between the protruding portion and the cover plate 12, and a cap-blocking channel 33 is formed between the protruding portion and the cover plate 12, and the cap-blocking channel 33 is used to allow the qualified bottle caps 100 to pass through and to limit the qualified bottle caps 100. When the qualified bottle caps 100 are conveyed to the cap-blocking member 31, since the height of the cap-blocking channel 33 matches the thickness of the cap bottom 102 of the qualified bottle caps 100, that is, the edge of one side of the cap bottom 102 of the qualified bottle caps 100 can just enter and pass through the cap-blocking channel 33, when the air blowing member 32 blows air, the edge of one side of the cap bottom 102 of the qualified bottle caps 100 is in the cap-blocking channel 33, and the upper surface of the edge of one side of the cap bottom 102 of the qualified bottle caps 100 can be The lower edge of the raised portion is blocked, so that the air blowing member 32 cannot blow the bottle cap 100 into the rotating warehouse body 11; when the unqualified bottle cap 100 is transported to the cap blocking member 31, the unqualified bottle cap 100 cannot enter the cap blocking channel 33 due to the limited height of the cap blocking channel 33, and the raised portion of the cap blocking member 31 contacts part of the unqualified bottle cap 100, thereby pushing the unqualified bottle cap 100, which can prevent the unqualified bottle cap 100 from being stuck in the cap blocking channel 33. The cap blocking member 31 can not only push the unqualified bottle cap 100, but also limit the qualified bottle cap 100, and the structure is simple and reasonable.

[0046] Preferably, in this embodiment, a fixed wall is further fixedly provided on the outer periphery of the cover plate 12 to prevent the bottle caps 100 from being thrown out of the cover plate 12 under the action of centrifugal force during the rotating conveying process on the cover plate 12 .

[0047] Specifically, in this embodiment, when the inverted cover is transported to the cover-blocking member 31, the cover bottom 102 of the inverted cover cannot enter the cover-blocking channel 33 due to its tilt, and the cover bottom 102 of the inverted cover contacts the side of the protrusion. Some of the inverted covers fall into the rotating warehouse body 11 before being transported to the air-blowing member 32 due to the pushing of the protrusion of the cover-blocking member 31 or the unstable center of gravity during the transport process. The remaining inverted covers are blown into the rotating warehouse body 11 under the blowing action of the air-blowing member 32; Figure 8 As shown, when the reverse cover is conveyed to the cover blocking member 31, the cover bottom 102 of the reverse cover cannot enter the cover blocking channel 33 because it is facing upward. Some reverse covers fall into the rotating warehouse body 11 before being conveyed to the air blowing member 32 due to the pushing of the fixed wall or the unstable center of gravity during the conveying process. The remaining reverse covers are blown into the rotating warehouse body 11 under the blowing action of the air blowing member 32.

[0048] Preferably, if Figure 7As shown, in this embodiment, the height of the air outlet of the air blowing member 32 (the distance between the air outlet and the cover plate 12) is less than the thickness of the bottle cap 100 (i.e., the maximum distance from the end face of the cover bottom 102 to the end face of the cover column 101), and greater than the thickness of the cover bottom 102. A channel is formed between the air blowing member 32 and the cover blocking member 31, through which only the cover column 101 can pass, so that only qualified bottle caps 100 can pass, and unqualified bottle caps 100 are prevented from passing through and being missed, and the missed rejection rate is lower. Of course, if Figure 8 As shown, in other embodiments, the height of the air outlet of the air blowing member 32 can also be greater than the thickness of the bottle cap 100. The blowing force of the air blowing member 32 can better act on the bottle cap 100, resulting in a good rejection effect, and can also prevent the bottle cap 100 from being stuck between the air blowing member 32 and the blocking member 31, causing congestion of the upstream bottle cap 100.

[0049] Preferably, in this embodiment, the air outlet of the air blowing member 32 is arranged at the end of the material blocking channel 33, and the portion of the qualified bottle caps 100 pressed by the protrusion at the end of the material blocking channel 33 is the largest, and the limiting position is more stable; while the portion of the unqualified bottle caps 100 squeezed out here is the largest, making it easier for the unqualified bottle caps 100 to be blown into the rotating bin body 11, and the structure is reasonable.

[0050] Preferably, in this embodiment, the raised portion is in a wedge shape, and the width of the raised portion gradually increases along the conveying direction of the bottle caps 100. When the unqualified bottle caps 100 are conveyed to the cap-blocking member 31, the unqualified bottle caps 100 are gradually pushed, and the pushing process is stable; when the qualified bottle caps 100 are conveyed to the cap-blocking member 31, as the conveying distance of the qualified bottle caps 100 is closer to the air-blowing member 32, more and more of the edge of one side of the cap bottom 102 is pressed by the raised portion, and the qualified bottle caps 100 are pressed more and more stably, less likely to be wrongly rejected, and the wrong rejection rate is lower.

[0051] Preferably, in the present embodiment, the width of the material blocking channel 33 is narrow (the maximum width of the material blocking channel 33 is 1 / 10-1 / 4 of the width of the cover plate 12), which is only enough to enter the edge of the bottom 102 of the qualified bottle cap 100, while other parts of the bottle cap 100 cannot enter. The qualified bottle cap 100 can be limited in a targeted manner. The fewer parts of the bottle cap 100 are stuck, the less interference occurs between the bottle cap 100 and the material blocking channel 33, and the normal movement of the qualified bottle cap 100 is less likely to be affected, and the stability is higher.

[0052] Preferably, in the present embodiment, a baffle plate (not shown in the figure) is further provided upstream of the unqualified bottle cap returning mechanism 3, and the baffle plate is arranged obliquely along the conveying direction of the bottle caps 100. When the bottle caps 100 in the rotating bin body 11 move onto the cover plate 12, the bottle caps 100 may form two or even multiple columns in parallel, and the bottle caps 100 are gathered into one column by guiding the bottle caps 100 on the cover plate 12 by the baffle plate, so that when the bottle caps 100 on the cover plate 12 are conveyed to the unqualified bottle cap returning mechanism 3, they are a single column and continuous bottle caps 100, so that the actual width of the cover plate 12 downstream of the baffle plate is similar to the bottom diameter of the bottle caps 100, and the unqualified bottle caps 100 are not easy to stay on the cover plate 12, thereby reducing the pressure of the unqualified bottle cap returning mechanism 3 on rejecting and returning the unqualified bottle caps 100. Preferably, in this embodiment, a fixed wall is further fixedly provided on the outer periphery of the cover plate 12 to prevent the bottle caps 100 from being thrown out of the cover plate 12 under the action of centrifugal force during the rotating conveying process on the cover plate 12 .

[0053] Furthermore, if Figure 2 As shown, in this embodiment, the cover blocking member 31 is located on the side above the cover plate 12 away from the rotating warehouse body 11, and the air blowing member 32 is located on the side above the cover plate 12 close to the rotating warehouse body 11, so that the pushing force and blowing force exerted on the unqualified bottle caps 100 can be directed toward the rotating warehouse body 11, and the layout is reasonable.

[0054] Furthermore, if Figure 2 As shown, in this embodiment, an air blowing mechanism 4 is further provided on one side of the cap placing plate 12, and the air blowing mechanism 4 is used to blow the bottle caps 100 on the cap placing plate 12 into the rotating bin body 11 when the cap sorting channel 2 does not need to be fed with caps. When the cap sorting channel 2 is full of caps or the downstream discharging equipment needs to be temporarily stopped due to a malfunction or other reasons, the air blowing mechanism 4 is turned on to blow all the bottle caps 100 that are about to enter the cap sorting channel 2 into the rotating bin body 11, so as to prevent the bottle caps 100 from being blocked due to the inability to discharge the caps, and to maintain the continuous operation of the rotating bin 1. When the subsequent downstream equipment is restored and the caps need to be fed again, the air blowing mechanism 4 can be turned off to immediately resume the operation without waiting for the restart of the rotating bin 1, and the working continuity is high. Preferably, along the conveying direction of the bottle caps 100, the air blowing mechanism 4 is located upstream of the cap sorting channel 2 and the unqualified bottle cap returning mechanism 3, and all the bottle caps 100 are blown back into the rotating warehouse body 11 before the bottle caps 100 enter the unqualified bottle cap returning mechanism 3, which can reduce the repeated work of the unqualified bottle cap returning mechanism 3, reduce equipment loss, and make the operation process reasonable.

[0055] Furthermore, if Figures 3 to 5As shown, in this embodiment, a cap blowing mechanism 5 is further provided in the middle of the rotating warehouse body 11, and the cap blowing mechanism 5 is used to blow the bottle caps 100 in the rotating warehouse body 11 onto the capping plate 12. The cap blowing mechanism 5 blows air and cooperates with the centrifugal force of the rotating warehouse 1 to send the bottle caps 100 to the capping plate 12, and the capping efficiency is higher. Preferably, in this embodiment, the bottom of the rotating warehouse body 11 is connected to the capping plate 12 through an inclined transition plate, and the transition is smooth, and the capping is easier.

[0056] Furthermore, in this embodiment, the cap blowing mechanism 5 includes an air blowing component 51, a hanger 52, a rotating seat 53 and a moving seat 54. The hanger 52 is fixedly arranged above the rotating warehouse body 11, the rotating seat 53 is rotatably and adjustably arranged on the hanger 52, the moving seat 54 is movably and adjustably arranged on the rotating seat 53, and the air blowing component 51 is arranged on the moving seat 54. By arranging the rotating seat 53 and the moving seat 54, the air blowing direction and air blowing height of the air blowing component 51 can be flexibly adjusted, and can adapt to the air blowing direction and height when there are different numbers of bottle caps 100 in the rotating warehouse body 11, and the adaptability is strong.

[0057] Preferably, in this embodiment, the air blowing component 51 is an air blowing nozzle, and a plurality of air blowing channels are provided on the air blowing nozzle, so that the force of the airflow acting on the bottle cap 100 is more comprehensive.

[0058] Preferably, in this embodiment, the rotation axis of the rotating seat 53 is parallel to the rotation plane of the rotating chamber 1, so that the air blowing direction of the air blowing component 51 can be adjusted up and down.

[0059] Furthermore, if Figure 6 As shown, in this embodiment, a cap-missing detection mechanism 6 is further provided in the rotating warehouse body 11, and the cap-missing detection mechanism 6 is used to detect whether there is a cap missing in the rotating warehouse body 11. The cap-missing detection mechanism 6 includes a mounting seat 61, a detection plate 62 and a proximity switch 63. The mounting seat 61 is fixed above the rotating warehouse body 11, and the detection plate 62 is set on the mounting seat 61 so as to swing up and down. The proximity switch 63 is set on the mounting seat 61 and arranged corresponding to the detection plate 62. When there are fewer bottle caps 100 inside the rotating warehouse body 11, the detection plate 62 will swing down and approach the proximity switch 63 due to its own gravity. After sensing for a period of time, the proximity switch 63 will sound an alarm to remind the staff to add caps to the rotating warehouse body 11.

[0060] Furthermore, if Figure 4 As shown, in this embodiment, a cap guide mechanism 8 is provided in the rotating warehouse body 11, and the cap guide mechanism 8 is used to gather the bottle caps 100 in the rotating warehouse body 11. Through the gathering effect of the cap guide mechanism 8 on the bottle caps 100 in the rotating warehouse body 11, the bottle caps 100 can be better blown on by the cap blowing mechanism 5, and the capping efficiency is higher. Specifically, the cap guide mechanism 8 gathers the bottle caps 100 to the blowing position of the cap blowing mechanism 5.

[0061] Furthermore, if Figure 4 As shown, in this embodiment, an accelerating air blowing mechanism 9 is provided on the cap sorting channel 2, and the accelerating air blowing mechanism 9 blows air along the discharging direction of the cap sorting channel 2 to accelerate the discharging of the bottle caps 100. By blowing air to the bottle caps 100 in the cap sorting channel 2 by the accelerating air blowing mechanism 9, the discharging of the bottle caps 100 can be accelerated, and the discharging efficiency is higher.

[0062] Furthermore, if Figure 1 As shown, in this embodiment, the discharge port of the cap sorting channel 2 is connected to a discharge guide rail 7, and a vibration component 71 is provided on the discharge guide rail 7. When the arranged bottle caps 100 are transported, they are vibrated by the vibration component 71 to prevent the bottle caps 100 from interfering with each other on the discharge guide rail 7 and causing obstruction.

[0063] Furthermore, the present invention also provides a method for sorting caps by the above-mentioned cap sorting device, which comprises: placing bottle caps 100 into the rotating warehouse body 11 of the rotating warehouse 1; using a driving device to drive the rotating warehouse body 11 to rotate, adjusting the rotation speed of the rotating warehouse body 11 so that the bottle caps 100 can enter the cap-setting plate 12 under the action of centrifugal force, and the bottle caps 100 can enter the cap-blocking channel 33 as the cap-setting plate 12 rotates; adjusting the blowing volume of the air blowing member 32 so that the positive caps on the cap-setting plate 12 can stay on the cap-setting plate 12 when passing through the cap-blocking channel 33 without being blown back to the rotating warehouse body 11, and the reverse caps and inverted caps are blown back into the rotating warehouse body 11 before entering the cap-blocking channel 33 or when passing through the cap-blocking channel 33. Through this method, the cap sorting device can process the bottle caps 100 efficiently and stably, and the processed bottle caps 100 can be output to the place where the bottle caps 100 are needed in a specific direction.

[0064] Furthermore, when the bottle caps are not needed, the air inlet valve of the blowing mechanism 4 is opened, so that the bottle caps 100 on the capping plate 12 are blown back into the rotating bin body 11 when passing through the blowing mechanism 4. Through the operation of the air blowing mechanism 4, the cap sorting mechanism can be prevented from outputting the bottle caps without stopping the rotation of the rotating bin 11. Since the rotating bin body 11 continues to rotate, the capping of the capping plate 12 can proceed normally. Therefore, this method can avoid the impact of stopping the rotating bin body 11 on the equipment, and at the same time, when the outside world needs to input the bottle caps 100, the bottle caps 100 can be sorted and output in time.

[0065] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above in the preferred embodiment, it is not used to limit the present invention.
