Fig. 1 shows a partial perspective view of a cover supply system 1 according to an embodiment of the utility model. As shown in fig. 1, the cap supply system 1 includes a cap inlet 10, a cap carrier, a cap conveyance device, and a cap detection sensor 44. The cap carrying part includes a carrying disk 20, and is configured to convey caps supplied from the cap inlet 10 to a inspection station (not shown in the drawing) through the carrying disk 20, and convey qualified caps to a cap conveying device. The cover supply system 1 further comprises a controller (not shown in the figures) for controlling the various parts of the cover supply system 1.

The cap transfer device includes a cap supply port, a first transfer rail 31, a second transfer rail 32, and a split rail assembly. The carrier puck 20 delivers the inspected caps to the cap supply port, and the caps are selectively supplied to the first delivery rail 31 and/or the second delivery rail 32 by operation of the split rail assembly. The track-dividing assembly comprises a dial wheel 41, a driver 42, a support 43, a position sensor 45 and a displacement device 46.

Fig. 2 is a view similar to fig. 1, in which a portion of the track assembly (the click wheel 41 is not shown) is not shown to show the cap supply port 33, the cap supply port 33 being located in the tangential direction of the carrier disk 20. The direction in which the cap supply port 33 outputs the cap (first direction) coincides with the extending direction of the first conveying rail 31. The first conveying rail 31 has a first inlet 310, as shown in fig. 1 and 2, the first inlet 310 faces the cap supply port 33, and is adapted to receive 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 disposed opposite to each other in the width direction, and the first side frame 311 extends to the cap supply port 33 in the cap supply port 33 output direction (first direction) so that the first inlet 310 is aligned with the cap supply port 33. The second conveying rail 32 is located at a side of the second side frame 312, has a second inlet 320, and the second inlet 320 is directed toward the cap supply port 33 and is adapted to receive caps supplied from the cap supply port 33. As best shown in fig. 2, the first inlet 310 and the second inlet 320 are each directed toward the cap supply port 33, and the cap supply port 33 is located upstream of the first inlet 310 and the second inlet 320 in the cap conveyance direction and at the intersection of the extending direction of the first inlet 310 and the extending direction of the second inlet 320.

Referring back to fig. 1, the dial wheel 41 is provided with a plurality of dials 411 spaced apart from each other in the circumferential direction. The dial wheel 41 is disposed proximate to the cap supply port 33 such that one of the plurality of dials 411 can be located at the cap supply port 33 upstream of the first inlet 310 of the first conveyor rail 31 and the dials 411 are aligned with the first side frame 311 of the first conveyor rail 31 to allow a cap to enter the first conveyor rail 31 from the first inlet 310 or to be dialed to the second inlet 320 by the one dial. The plurality of paddles 411 of the paddle wheel 41 are uniformly disposed at the outer circumference of the paddle wheel 41, and the interval between two neighboring 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 greater than the outer diameter of the cap or the width of the first conveying rail 31, so as to facilitate the stable conveyance of the cap to the first conveying rail 31 through the gap between two neighboring paddles 411. The track assembly allows a lid to enter the first conveyor track 31 from the first inlet 310 of the first conveyor track 31 through a gap between one tab 411 at the lid supply port 33 aligned with the first side frame 311 of the first conveyor track 31 and an adjacent tab, or may cause the dial wheel 41 to be drivingly rotated to dial a lid supplied to the lid supply port 33 to the second inlet 320 of the second conveyor track 32 through the one tab at the lid supply port 33 aligned with the first side frame 311 of the first conveyor track 31.

The driver 42 is provided to drive the dial 41 to rotate. In one example, the driver 42 is a servo motor. However, the present utility model is not limited thereto. In other examples according to the utility model, the driver 42 may use any other suitable driving means. The dial wheel 41 and the driver 42 are each supported by a support 43. The click wheel 41 is rotatably connected to a support 43.

The position sensor 45 is used for zero calibration of the cover conveying device and is arranged to detect the rotational position of the click wheel 41. The position sensor 45 is arranged to detect the rotational position of the dial wheel 41 upon start-up of the cover supply system 1, i.e. upon start-up of the cover conveying means, and to send the detected position information to the driver 42, the driver 42 being arranged to selectively drive the dial wheel 41 to rotate to the calibration position in accordance with the position information. In the calibration position, one of the paddles 411 of the paddle wheel 41 is positioned at the cap supply port 33, the paddle 411 being aligned with the first side frame 311 of the first conveyor rail 31 to allow caps to enter the first conveyor rail 31 from the first inlet 310 or to be dialed by the paddle 411 to the second inlet 320. The position sensor 45 is located outside the dial 41 and is provided to detect a position of one of the plurality of dials on the outer circumference of the dial 41. As described above, the plurality of paddles of the paddle wheel 41 are uniformly disposed on the outer periphery of the paddle wheel 41, and therefore, by detecting the position of one of the paddles, the position of the other paddles can be determined therefrom, for example, the position of the paddle close to the first conveying rail 31 among the plurality of paddles. In the case where the dial wheel 41 is vertically disposed as shown in the drawing, the dial adjacent to the first conveying rail 31 is a dial located below among the plurality of dials of the dial wheel 41.

In the example shown in the figures, a position sensor 45 is mounted on the outside of the click wheel 41 and above the click wheel 41, the position sensor 45 being arranged to detect the position of the upper click piece of the click wheel 41 when the cover system 1 is started up, whereby the position of the lower click piece of the plurality of click pieces close to the first conveying rail 31 can be determined. However, the present utility model is not limited thereto. The position sensor 45 may be installed at other suitable positions as long as it is convenient to detect the position of the dial wheel 41 near the first conveying rail 31 and does not interfere with the operation of other devices. When the underlying paddle adjacent to the first conveying rail 31 is already at the cover supply port 33, more specifically when it is aligned with the first side frame 311 of the first conveying rail 31 at the cover supply port 33, it is explained that the paddle wheel 41 is already in the calibration position at this time, so that there is no need to rotate the paddle wheel 41. When the lower paddle adjacent to the first conveying rail 31 is not located at the cover supply port 33 and is not aligned with the first side frame 311, it is indicated that the paddle wheel 41 is not in the calibration position, and at this time, the driver 42 drives the paddle wheel 41 to rotate the paddle wheel 41 to the calibration position. Only when the dial wheel 41 is in the calibration position, the cap conveying means starts conveying caps to the first conveying rail 31 or the second conveying rail 32. Since the plurality of paddles 411 are uniformly disposed on the outer circumference of the paddle wheel 41 and the paddle wheel 41 is driven to rotate at a step pitch corresponding to the interval between adjacent paddles each time during cap conveyance, once the paddle wheel 41 is in the calibration position, even if the paddle wheel 41 is driven to rotate to dial a cap to the second inlet 320 of the second conveying rail 32 during subsequent cap conveyance, the other paddle of the rotated paddle 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, and thus, the above zero calibration is not required during subsequent cap conveyance. Therefore, the position sensor 45 performs the above detection only when the cover supply system 1 is started up.

Fig. 3 shows a rotational position of the click wheel 41, and fig. 4 shows a partial enlargement of fig. 3. As shown in fig. 3 and 4, one of the paddles 411 of the paddle wheel 41 is located near the cap supply port 33 and near the first conveying rail 31, but is not aligned with the first side frame 311, but 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, on the conveying path where the cap supply port 33 outputs the cap, and at this time, the paddles 411 will interfere with the cap being conveyed to the downstream first conveying rail 31 or the second conveying rail 32. When the position sensor 45 detects that one of the paddles 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, indicating that the paddle 41 is not in the aligned position at this time, the paddles will interfere with the conveying of the caps to the downstream first conveying rail 31 or the second conveying rail 32, whereupon the driver 42 drives the paddle 41 to rotate to the aligned position such that the paddles 411 are aligned with the first side frame 311 of the first conveying rail 31 so as not to interfere with the conveying of the caps to the first conveying rail 31 and is adapted to dial the caps to the second inlets 320 of the second conveying rail 32 as needed. For example, the dial wheel 41 may be rotated clockwise in fig. 3 and 4 such that the dial 411 indicated in the drawings is aligned with the first side frame 311. Or the click wheel 41 may be rotated counterclockwise in the drawing so that another click 411A located near the click shown in the drawing is aligned with the first side frame 311. At the time of zero calibration, the rotation direction of the dial wheel 41 may be determined according to the distance of the dial 411 of the dial wheel 41 from the first side frame 311 and the second side frame 312 in the width direction of the first conveying rail 31, so that zero calibration is completed by the rotation of the dial wheel 41 by a small angle.

The displacement means 46 are arranged to cause the dial wheel 41 to be rapidly moved away from the cap supply port 33 when a cap jam occurs in the cap transfer means, in order to rapidly handle the jam. Referring back to fig. 1, the displacement device 46 includes a movable member 461 and a fixed seat 462. The movable member 461 is fixedly coupled to the support 43 of the dial wheel 41 and is movably attached to the fixed seat 462. The movable member 461 is longitudinally movable relative to the fixed seat 462, thereby driving the click wheel 41 and its driver 42 to move longitudinally. In the example shown in the drawings, the movable member 461 and the fixed seat 462 are movably connected to each other by a slide rail fitting structure of a slide groove. A slide groove is provided on one of the movable member 461 and the fixed seat 462, and a slide rail is provided on the other of the movable member 461 and the fixed seat 462 in correspondence with the slide groove so that the movable member 461 can move relative to the fixed seat 462. However, the present utility model is not limited thereto, and in other examples according to the present utility model, the movable member 461 and the fixed mount 462 may be movably connected to each other by other suitable mating structures. In the example shown in the figures, the dial wheel 41 is arranged longitudinally above the cap supply port 33, and the displacement means 46 may move the dial wheel 41 longitudinally away from or towards the cap supply port 33. However, the present utility model is not limited thereto, and in other examples according to the present utility model, the dial wheel 41 may be laterally disposed at one side of the cap supply port 33, and accordingly, the displacement device 46 may be configured to move the dial wheel 41 laterally to be away from or close to the cap supply port 33.

Preferably, the cap conveyor may further be provided with a blowing device, the blowing pipe 47 of which is configured to blow gas toward the second conveyor rail 32 to accelerate the conveyance of the caps in the second conveyor rail 32. As shown in fig. 2, and most preferably, as shown in fig. 3, the second conveying track 32 includes a connecting section 321, an extending section 323, and a transition section 322. The connecting section 321 is located between the second inlet 320 and the transition section 322 of the second conveying rail 32. In one example, the second inlet 320 of the second conveying rail 32 may be an inlet of the connecting section 321. In the example shown in the figure, the direction in which the cap supply port 33 outputs the cap (first direction) coincides with the extending direction of the first conveying rail 31, and the first side frame 311 extends in the first direction and aligns the first inlet 310 with the cap supply port 33. The connecting section 321 of the second conveying rail 32 is disposed at an angle to the direction in which the cap supply port 33 outputs a cap. The extension 323 extends in a direction parallel to the direction in which the cap supply port 33 outputs the cap (first direction), that is, in parallel to the first conveying rail 31. Transition section 322 is located between connecting section 321 and extending section 323, connecting section 321 to extending section 323.

The blowing means are arranged to blow gas from the outside of the second conveying rail 32 through the blowing pipe 47 towards the transition section 322 of the second conveying rail 32, thereby facilitating a rapid conveying of the caps to the extension section 323 of the second conveying rail 32 after the caps have been toggled to the second inlet 320 of the second conveying rail 32 and out of the connection section 321. The inflation tube 47 is made of a deformable material. Thus, although the outlet of the air duct 47 is shown not facing the transition section 322 of the second conveyor rail 32, in use, the air duct 47 may be curved such that the outlet of the air duct 47 faces the transition section 322 of the second conveyor rail 32 to accelerate the transport of caps from the transition section 322 to the extension section 323.

Referring back to fig. 1 and 2, a cap detection sensor 44 is provided to detect the position of the clamp holding the cap. Specifically, the cap detection sensor 44 detects that the jig 21 holding the cap P is aligned with the access cap port 33. When the cap detection device 45 detects that the clamp 21 holding the cap is aligned with the cap supply port 33, the clamp 32 is controlled to release the cap P to the cap supply port 33, and the cap P is selectively supplied to the first conveying rail 31 or the second conveying rail 32 by the operation of the split rail assembly. In the example shown in the figures, the cover detection sensor 44 is mounted on a mounting frame above the carrier disk 20. However, the present utility model is not limited thereto. In other examples according to the utility model, the cover detection sensor 44 may be mounted at other suitable locations as long as it does not interfere with the operation of other devices.

When it is desired to convey the caps to the first conveying rail 31, the dial 41 is kept at the aligned position without rotation, i.e., one of the dials 411 of the dial 41 located below is aligned with the first side frame 311 of the first conveying rail 31 without impeding the caps from being supplied to the first conveying rail 31. Then, the cover P is conveyed to the first conveying rail 31 by the first inlet 310 of the first conveying rail 31 through a gap between the plectrum aligned with the first side frame 311 and the adjacent plectrum under the guide of the first side frame 311 of the first conveying rail 31.

When it is desired to transport the caps to the second transport rail 32, when the clamp 21 releases the caps P to the cap supply port 33, the driver 42 drives the dial wheel 41 to rotate by an angle such that the dials of the dial wheel 41 dial the caps P to the second inlet 320 of the second transport rail 32, and then the caps P are transported to the extension 323 via the connection section 321, the transition section 322. This angle of rotation of the dial wheel 41 corresponds to the angle between adjacent dials 411 such that, after rotating the angle to dial the cover P into the second entrance 320 of the second conveying rail 32, the next dial 411 of the dial wheel 41 is aligned with the first side frame 311 of the first conveying rail 31 in preparation for the separating operation of the next cover.

When it is necessary to alternately convey the plurality of caps supplied from the carrier tray to the first conveying rail 31 and the second conveying rail 32, the dial wheel 41 may be rotated and stopped at a predetermined cycle. The predetermined period may be determined according to the ratio of caps respectively transferred to the first and second transfer rails 31 and 32 and the transfer speed.

When a cap is jammed by accumulating in the vicinity of the cap supply port 33, for example, when the cap is jammed in the vicinity of the dial 411 in the second supply rail 32, the shift device 46 may move the dial wheel 41 longitudinally upward, away from the cap supply port 33, to facilitate quick handling of the jam. After the jam is eliminated, the shifting device 46 moves the click wheel 41 longitudinally downward, close to the cap supply port 33, to continue the cap conveyance.

The above shows exemplary embodiments of a cap transfer device and a cap supply system according to the present utility model. According to the cap conveying device and the cap supply system, the mechanical type rail separating assembly is adopted, caps can be rapidly supplied to corresponding conveying rails according to requirements, different requirements of a downstream filling line are met, and cap supply efficiency is improved. In one example, the cap conveyor according to the present utility model is capable of achieving a cap feed speed of 24000 pieces/hour. Moreover, the cover conveying device and the cover supplying system adopt a shifting device, so that when the cover is blocked, the poking wheel 41 can be quickly moved away from the cover supplying port 33, thereby being beneficial to quickly treating the blockage.

Herein, exemplary embodiments of the present utility model have been described in detail, but it should be understood that the present utility model is not limited to the specific embodiments described and illustrated in the above. Those skilled in the art will be able to make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. All such modifications and variations are intended to be within the scope of the present utility model. Moreover, all the components described herein may be replaced by other technically equivalent elements.
