[0028] Figure 1 FIG. 1 shows a partial stereoscopic view of a cover supply system 1 according to an embodiment of the present utility model. Figure 1 As shown, the cap supply system 1 includes a cap inlet 10, a cap carrier, a cap conveying device, and a cap detection sensor 44. The cap carrier includes a carrier disc 20, and is configured to transport the caps supplied from the cap inlet 10 to a detection station (not shown in the figure) through the carrier disc 20, and to transport the caps that have passed the detection to the cap conveying device. The cap supply system 1 also includes a controller (not shown in the figure) for controlling various parts of the cap supply system 1.

[0029] The cap conveying device includes a cap supply port, a first conveying rail 31, a second conveying rail 32 and a track dividing assembly. The carrier disc 20 conveys the qualified caps to the cap supply port, and the caps are selectively supplied to the first conveying rail 31 and / or the second conveying rail 32 through the operation of the track dividing assembly. The track dividing assembly includes a toggle wheel 41, a driver 42, a support 43, a position sensor 45 and a shifting device 46.

[0030] Figure 2 is with Figure 1 A similar view is shown, in which a part of the rail dividing assembly is not shown (the toggle wheel 41 is not shown) to show the cap supply port 33, which is located in the tangential direction of the carrying disk 20. The direction (first direction) in which the caps are output from the cap supply port 33 is consistent with the extending direction of the first conveying rail 31. The first conveying rail 31 has a first inlet 310, such as Figure 1 and Figure 2As shown, the first inlet 310 faces the cap supply port 33 and is suitable for receiving the caps supplied from the cap supply port 33. The first conveying rail 31 includes a first side frame 311 and a second side frame 312 arranged opposite to each other in the width direction. The first side frame 311 extends to the cap supply port 33 along the direction (first direction) in which the caps are output from the cap supply port 33, so that the first inlet 310 is aligned with the cap supply port 33. The second conveying rail 32 is located on the side where the second side frame 312 is located, and has a second inlet 320. The second inlet 320 faces the cap supply port 33 and is suitable for receiving the caps supplied from the cap supply port 33. Figure 2 As best shown in the figure, both the first inlet 310 and the second inlet 320 face the cap supply port 33. In the cap conveying direction, the cap supply port 33 is located upstream of the first inlet 310 and the second inlet 320, and is located at the intersection of the extension direction of the first inlet 310 and the extension direction of the second inlet 320.

[0031] Return to see Figure 1 , the toggle wheel 41 is provided with a plurality of paddles 411 spaced apart from each other in the circumferential direction. The toggle wheel 41 is arranged close to the cap supply port 33, so that one of the plurality of paddles 411 can be located at the cap supply port 33, upstream of the first entrance 310 of the first conveying rail 31, and the paddle 411 is aligned with the first side frame 311 of the first conveying rail 31, so as to allow the cap to enter the first conveying rail 31 from the first entrance 310, or to allow the cap to be toggled to the second entrance 320 by the one paddle. The plurality of paddles 411 of the toggle wheel 41 are evenly arranged on the outer circumference of the toggle wheel 41, and the interval between two adjacent paddles 411 corresponds to the outer diameter of the cap to be conveyed or the width of the first conveying rail 31, and is equal to or slightly larger than the outer diameter of the cap or the width of the first conveying rail 31, so as to facilitate the cap to be stably conveyed to the first conveying rail 31 through the gap between two adjacent paddles 411. The split track assembly allows the cover to enter the first conveying rail 31 from the first entrance 310 of the first conveying rail 31 through a gap between a paddle 411 located at the cover supply port 33 and aligned with the first side frame 311 of the first conveying rail 31 and an adjacent paddle, or it can enable the paddle wheel 41 to be driven to rotate so as to paddle the cover supplied to the cover supply port 33 to the second entrance 320 of the second conveying rail 32 through the paddle located at the cover supply port 33 and aligned with the first side frame 311 of the first conveying rail 31.

[0032] The driver 42 is configured to drive the toggle wheel 41 to rotate. In one example, the driver 42 is a servo motor. However, the present invention is not limited thereto. In other examples according to the present invention, the driver 42 can use any other suitable driving device. The toggle wheel 41 and the driver 42 are both supported by a support 43. The toggle wheel 41 is rotatably connected to the support 43.

[0033] The position sensor 45 is used for zero position calibration of the cap conveying device, and is configured to detect the rotation position of the toggle wheel 41. The position sensor 45 is configured to detect the rotation position of the toggle wheel 41 when the cap supply system 1 is turned on, that is, when the cap conveying device is started, and send the detected position information to the driver 42, and the driver 42 is configured to selectively drive the toggle wheel 41 to rotate to the calibration position according to the position information. At the calibration position, a paddle 411 of the toggle wheel 41 is located at the cap supply port 33, and the paddle 411 is aligned with the first side frame 311 of the first conveying rail 31 to allow the cap to enter the first conveying rail 31 from the first entrance 310, or to allow the cap to be toggled to the second entrance 320 by the paddle 411. The position sensor 45 is located outside the toggle wheel 41, and is configured to detect the position of one of the plurality of paddles on the outer periphery of the toggle wheel 41. As described above, the plurality of paddles of the paddle wheel 41 are evenly arranged on the outer circumference of the paddle wheel 41. Therefore, by detecting the position of one of the paddles, the positions of the other paddles can be determined, for example, the position of the paddle close to the first conveying rail 31 among the plurality of paddles can be determined. In the case where the paddle wheel 41 is arranged vertically as shown in the figure, the paddle close to the first conveying rail 31 is the paddle located at the bottom among the plurality of paddles of the paddle wheel 41.

[0034] In the example shown in the figure, the position sensor 45 is installed on the outside of the toggle wheel 41 and is located above the toggle wheel 41. The position sensor 45 is configured to detect the position of the upper paddle of the toggle wheel 41 when the cap supply system 1 is turned on, thereby determining the position of the lower paddle close to the first conveying rail 31 among the multiple paddles. However, the utility model is not limited to this. The position sensor 45 can be installed at other suitable positions as long as it is convenient to detect the position of the paddle of the toggle wheel 41 close to the first conveying rail 31 and does not hinder the operation of other devices. When the lower paddle close to the first conveying rail 31 is already at the cap supply port 33, more specifically, when the paddle is aligned with the first side frame 311 of the first conveying rail 31 at the cap supply port 33, it means that the toggle wheel 41 is already in the calibration position at this time, so there is no need to rotate the toggle wheel 41. When the lower paddle close to the first conveying rail 31 is not located at the cap supply port 33 and is not aligned with the first side frame 311, it means that the toggle wheel 41 is not in the calibration position. At this time, the driver 42 drives the toggle wheel 41 to rotate the toggle wheel 41 to the calibration position. Only when the toggle wheel 41 is in the calibration position, the cap conveying device starts to convey caps to the first conveying rail 31 or the second conveying rail 32. Since a plurality of paddles 411 are evenly arranged on the periphery of the toggle wheel 41, and the toggle wheel 41 is driven to rotate at a step corresponding to the interval between adjacent paddles each time during the cap conveying process, once the toggle wheel 41 is in the calibration position, even if the toggle wheel 41 is driven to rotate to toggle the cap to the second entrance 320 of the second conveying rail 32 during the subsequent cap conveying process, another paddle of the rotated toggle wheel 41 will be located at the cap supply port 33, more specifically, aligned with the first side frame 311 of the first conveying rail 31, so in the subsequent cap conveying process, the above-mentioned zero position calibration is no longer required. Therefore, the position sensor 45 performs the above detection only when the cap supply system 1 is powered on.

[0035] Figure 3 shows a rotational position of the toggle wheel 41, Figure 4 Shows Figure 3 A partial enlarged view of Figure 3 and Figure 4As shown, a paddle 411 of the paddle wheel 41 is close to the cover supply port 33 and the first conveying rail 31, but is not aligned with the first side frame 311. Instead, it is located between the first side frame 311 and the second side frame 312 of the first conveying rail 31 in the width direction of the first conveying rail 31, and is located on the conveying path for outputting covers from the cover supply port 33. At this time, the paddle 411 will hinder the covers from being conveyed to the downstream first conveying rail 31 or the second conveying rail 32. When the position sensor 45 detects that a paddle 411 is not aligned with the first side frame 311 of the first conveying rail 31 but is located between the first side frame 311 and the second side frame 312 in the width direction of the first conveying rail 31, it means that the toggle wheel 41 is not in the calibration position at this time, and the paddle will hinder the cap from being conveyed to the downstream first conveying rail 31 or the second conveying rail 32, so the driver 42 drives the toggle wheel 41 to rotate to the calibration position, so that the paddle 411 is aligned with the first side frame 311 of the first conveying rail 31, so as not to hinder the cap from being conveyed to the first conveying rail 31, and is suitable for toggling the cap to the second entrance 320 of the second conveying rail 32 as needed. For example, the toggle wheel 41 can be moved along Figure 3 and Figure 4 The paddle wheel 41 can be rotated clockwise in the figure so that the paddle 411 indicated in the figure is aligned with the first side frame 311. Alternatively, the paddle wheel 41 can be rotated counterclockwise in the figure so that another paddle 411A located near the paddle shown in the figure is aligned with the first side frame 311. During the zero position calibration, the rotation direction of the paddle wheel 41 can be determined according to the distance between the paddle 411 of the paddle wheel 41 and the first side frame 311 and the second side frame 312 along the width direction of the first conveying rail 31, so that the zero position calibration is completed by rotating the paddle wheel 41 at a smaller angle.

[0036] The shifting device 46 is configured to quickly move the shifting wheel 41 away from the cap supply port 33 when a cap jam occurs in the cap conveying device, so as to quickly deal with the jam. Figure 1, the shifting device 46 includes a movable part 461 and a fixed seat 462. The movable part 461 is fixedly connected to the support 43 of the toggle wheel 41 and is movably attached to the fixed seat 462. The movable part 461 can move longitudinally relative to the fixed seat 462, thereby driving the toggle wheel 41 and its driver 42 to move longitudinally. In the example shown in the figure, the movable part 461 and the fixed seat 462 are movably connected to each other through a slide groove and a slide rail matching structure. A slide groove is set on one of the movable part 461 and the fixed seat 462, and a slide rail matching with the slide groove is set at a corresponding position on the other of the movable part 461 and the fixed seat 462, so that the movable part 461 can move relative to the fixed seat 462. However, the utility model is not limited to this. In other examples according to the utility model, the movable part 461 and the fixed seat 462 can be movably connected to each other through other suitable matching structures. In the example shown in the figure, the toggle wheel 41 is longitudinally arranged above the cover supply port 33, and the shifting device 46 can make the toggle wheel 41 move longitudinally to leave or approach the cover supply port 33. However, the present invention is not limited thereto, and in other examples according to the present invention, the toggle wheel 41 can be transversely arranged on one side of the cover supply port 33, and accordingly, the shifting device 46 can be configured to move the toggle wheel 41 transversely to leave or approach the cover supply port 33.

[0037] Preferably, the cap conveying device may also be provided with a blowing device, wherein the blowing pipe 47 of the blowing device is configured to blow gas toward the second conveying rail 32 to speed up the conveying of the caps in the second conveying rail 32. Figure 2 As shown, and optimally, as Figure 3 As shown, the second conveying rail 32 includes a connecting section 321, an extension section 323 and a transition section 322. The connecting section 321 is located between the second entrance 320 of the second conveying rail 32 and the transition section 322. In one example, the second entrance 320 of the second conveying rail 32 can be the entrance of the connecting section 321. In the example shown in the figure, the direction (first direction) in which the cover supply port 33 outputs the cover is consistent with the extension direction of the first conveying rail 31, and the first side frame 311 extends along the first direction and aligns the first entrance 310 with the cover supply port 33. The connecting section 321 of the second conveying rail 32 is arranged at an angle to the direction in which the cover supply port 33 outputs the cover. The extension section 323 extends in a direction parallel to the direction (first direction) in which the cover supply port 33 outputs the cover, that is, an extension parallel to the first conveying rail 31. The transition section 322 is located between the connecting section 321 and the extension section 323, connecting the connecting section 321 to the extension section 323.

[0038] The blowing device is configured to blow gas from the outside of the second conveying rail 32 toward the transition section 322 of the second conveying rail 32 through the blowing pipe 47, so that after the cap is moved to the second inlet 320 of the second conveying rail 32 and sent out from the connecting section 321, it is beneficial for the cap to be quickly transported to the extension section 323 of the second conveying rail 32. The blowing pipe 47 is made of a deformable material. Therefore, although the outlet of the blowing pipe 47 is not shown to be toward the transition section 322 of the second conveying rail 32 in the figure, when in use, the blowing pipe 47 can be bent so that the outlet of the blowing pipe 47 is toward the transition section 322 of the second conveying rail 32 to accelerate the conveying of the cap from the transition section 322 to the extension section 323.

[0039] Return to see Figure 1 and Figure 2 , the cover detection sensor 44 is configured to detect the position of the fixture holding the cover. Specifically, the cover detection sensor 44 detects that the fixture 21 holding the cover P is aligned with the cover supply port 33. When the cover detection device 45 detects that the fixture 21 holding the cover is aligned with the cover supply port 33, the fixture 32 is controlled to release the cover P to the cover supply port 33, and through the operation of the split track assembly, the cover P is selectively supplied to the first conveying rail 31 or the second conveying rail 32. In the example shown in the figure, the cover detection sensor 44 is mounted on a mounting frame above the carrier disc 20. However, the utility model is not limited to this. In other examples according to the utility model, the cover detection sensor 44 can be installed at other suitable positions as long as it does not interfere with the operation of other devices.

[0040] When it is necessary to convey the cap to the first conveying rail 31, the toggle wheel 41 is kept in the calibration position without rotating, that is, a paddle 411 located at the bottom of the toggle wheel 41 is aligned with the first side frame 311 of the first conveying rail 31, and does not hinder the cap from being supplied to the first conveying rail 31. Thus, under the guidance of the first side frame 311 of the first conveying rail 31, the cap P is conveyed to the first conveying rail 31 from the first entrance 310 of the first conveying rail 31 through the gap between the paddle aligned with the first side frame 311 and the adjacent paddle.

[0041] When it is necessary to transport the cap to the second transport rail 32, when the clamp 21 releases the cap P to the cap supply port 33, the driver 42 drives the toggle wheel 41 to rotate an angle, so that the paddle of the toggle wheel 41 toggle the cap P to the second entrance 320 of the second transport rail 32, and then the cap P is transported to the extension section 323 through the connecting section 321 and the transition section 322. The angle of rotation of the toggle wheel 41 corresponds to the angle between adjacent paddles 411, so that after rotating the angle to pry the cap P into the second entrance 320 of the second transport rail 32, the next paddle 411 of the toggle wheel 41 is aligned with the first side frame 311 of the first transport rail 31 to prepare for the next cap separation operation.

[0042] When it is necessary to alternately convey the plurality of caps supplied by the carrier disk to the first conveying rail 31 and the second conveying rail 32, the toggle wheel 41 can be rotated and stopped at a predetermined cycle. The predetermined cycle can be determined according to the ratio of the caps conveyed to the first conveying rail 31 and the second conveying rail 32 respectively and the conveying speed.

[0043] When the caps are accumulated and blocked near the cap supply port 33, for example, when the caps are blocked near the paddle 411 in the second supply rail 32, the shifting device 46 can move the paddle wheel 41 longitudinally upward to leave the cap supply port 33, so as to facilitate rapid handling of the blockage. After the blockage is eliminated, the shifting device 46 moves the paddle wheel 41 longitudinally downward to approach the cap supply port 33 to continue conveying the caps.

[0044] The above shows an exemplary embodiment of the cap conveying device and the cap supply system according to the utility model. The cap conveying device and the cap supply system according to the utility model adopt a mechanical rail-dividing assembly, which can quickly supply the caps to the corresponding conveying rails as needed, meet the different needs of the downstream filling lines, and help improve the efficiency of cap supply. In one example, the cap conveying device according to the utility model can reach a cap supply speed of 24,000 pieces / hour. In addition, the cap conveying device and the cap supply system according to the utility model adopt a shifting device, which can quickly move the toggle wheel 41 away from the cap supply port 33 when the cap is blocked, which is conducive to quickly dealing with the blockage.

[0045] Here, the exemplary embodiments of the utility model have been described in detail, but it should be understood that the utility model is not limited to the specific embodiments described and shown in detail above. Without departing from the purpose and scope of the utility model, those skilled in the art can make various modifications and variations to the utility model. All these modifications and variations fall within the scope of the utility model. Moreover, all components described herein can be replaced by other technically equivalent components.
