[0002] The beverage industry is constantly evolving. Conventional beverage caps are mostly threaded seals, approximately 10mm high. However, to achieve more functionalities, such as solid-liquid separation, taller caps are now being used instead of shorter ones, screwing onto the bottle opening. These caps are typically quite tall; for example, honey caps are approximately 60mm high.

[0003] Existing production lines are often designed based on the dimensions of lids of a single height, and can only transport and cap lids of that single height, making them incompatible with lids of significantly different heights. In other words, lids of different heights cannot share the same mechanism, otherwise, situations may occur such as lids that are too tall getting stuck in the conveyor channel or lids that are too short falling off the conveyor channel.

[0035] 200, First lid; 300, Second lid. Detailed Implementation

[0036] Reference Figures 1 to 4As shown, the cap feeding and dispensing device of this embodiment includes a cap guiding mechanism 1 and at least two cap feeding mechanisms 2. The cap guiding mechanism 1 can be used to transport caps of different heights to the cap gripping station. Specifically, the first cap 200 is a conventional beverage cap. The height of the first cap 200 is approximately 10mm. In practice, the height range of the first cap 200 can be from 10mm to 13.5mm. The second cap 300 is a honey cap, milk tea cap, sports cap, etc. The height of the second cap 300 is approximately 60mm. The height range of the second cap 300 can also be from 30mm to 65mm. Specifically, in one embodiment, the second cap 300 is a honey cap, and the height of the honey cap is 60.5mm. The cap guiding mechanism 1 can transport the first cap 200 and the second cap 300 of different heights to the cap gripping station respectively.

[0037] Furthermore, all the cap-feeding mechanisms 2 are spaced apart from each other on the outer periphery of the cap-guiding mechanism 1. Each cap-feeding mechanism 2 has a first conveying body 212, which has a first channel 2120 adapted to the height of the cap. The width of the first channel 2120 provided in all the cap-feeding mechanisms 2 is different. Specifically, all the cap-feeding mechanisms 2 are located on the outer periphery of the cap-guiding mechanism 1. In one embodiment, as shown... Figure 1 and Figure 2 As shown, the cap feeding mechanism 2 includes a first cap feeding mechanism 21 and a second cap feeding mechanism 22. The first cap feeding mechanism 21 and the second cap feeding mechanism 22 are spaced apart along the outer periphery of the cap guiding mechanism 1, and the first cap feeding mechanism 21 and the second cap feeding mechanism 22 are arranged at an angle. The first cap feeding mechanism 21 is used to transport the first cap 200 to the cap guiding mechanism 1, and the second cap feeding mechanism 22 is used to transport the second cap 300 to the cap guiding mechanism 1. Since the height of the second cap 300 is greater than the height of the first cap 200, the first channel 2120 provided by the first cap feeding mechanism 21 is a first through groove, and the width of the first through groove is adapted to the height of the first cap 200; the first channel 2120 provided by the second cap feeding mechanism 22 is a second through groove, and the width of the second through groove is adapted to the height of the second cap 300, so that the first cap 200 and the second cap 300 are each transported in the first conveying body 212 of the corresponding cap feeding mechanism 2, and are not easily jammed or detached. This cap feeding and cap separating device can accommodate at least two caps of different heights. By arranging the first cap-feeding mechanism 21 and the second cap-feeding mechanism 22 at intervals along the outer periphery of the cap-guide mechanism 1, the space of the outer periphery of the cap-guide mechanism 1 is made reasonable use. The included angle between the first cap-feeding mechanism 21 and the second cap-feeding mechanism 22 can be between 15 degrees and 60 degrees.

[0038] In some embodiments, the first channel 2120 is provided with a turning section 2122. The inlet end of the turning section 2122 faces a first direction, which is the height direction of the guide cover mechanism 1. The outlet end of the turning section 2122 is curved toward the center of the guide cover mechanism 1, and the outlet end of the turning section 2122 is located below the inlet end of the turning section 2122. Specifically, refer to... Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the lid enters the first channel 2120 in a horizontal position, meaning the central axis of the lid is perpendicular to the axis of the first channel 2120. (Refer to...) Figure 7 As shown, after entering from a horizontal position, the lid transitions to an upright position via a turning section 2122, where the central axis of the lid is parallel to the axis of the first channel 2120. Preferably, in one embodiment, the first conveying body 212 is configured as a square tube structure, including two limiting plates connected and fixed to each other by fasteners. A first channel 2120 for conveying the lid is located between the two limiting plates. The height of the second lid 300 is six times the height of the first lid 200. The first channel 2120 of the first lid-feeding mechanism 21 is a first through groove, and the first channel 2120 of the second lid-feeding mechanism 22 is a second through groove, the width of which is six times the width of the first through groove. Further, the second lid 300 has a constricted opening structure, and a limiting structure can be protruding inside the first conveying body 212 corresponding to the constricted opening structure to ensure that the second lid 300 does not tilt during conveying within the first channel 2120. (Refer to...) Figure 5 and Figure 7 As shown, by setting the turning section 2122, the cover naturally transitions from a horizontal state to an upright state after entering from the horizontal state. No additional components are needed to assist the cover in changing from a horizontal to an upright state. This also facilitates the sequential arrangement and conveying of the covers in the first conveyor body 212 within the first channel 2120, reducing waiting time and improving conveying efficiency. The turning section 2122 can be set as a semi-circular arc.

[0039] Optionally, the first channel 2120 further includes a straight section 2121 extending along a first direction and a flat conveying section 2123 extending along a second direction; the straight section 2121 is connected to the inlet end of the turning section 2122, and the flat conveying section 2123 is connected to the outlet end of the turning section 2122. The second direction is perpendicular to the first direction to ensure that the lid can smoothly transition from a horizontal state to an upright state in the first conveyor body 212, and also to make the lid conveyed more smoothly in the first conveyor body 212, so as to facilitate the sequential arrangement and conveying of more lids in the first conveyor body 212.

[0040] Furthermore, the cap feeding and dispensing device also includes a cap gripping mechanism 4, located at the cap gripping station. The cap gripping mechanism 4 has a screw-on head or a gripping head 41 to grasp the first cap 200 or the second cap 300 at the cap gripping station and to rotate and screw the first cap 200 or the second cap 300 into the bottle body. There is a gap between the cap gripping station and the cap feeding mechanism 2. To guide the first cap 200 or the second cap 300 to the cap gripping station one by one, the cap feeding and dispensing device provides a cap guiding mechanism 1 between the cap gripping station and the cap feeding mechanism 2. Since the first cap 200 and the second cap 300 are each conveyed by their respective first cap feeding mechanism 21 and second cap feeding mechanism 22, they are less likely to get stuck or fall off; and both the first cap 200 and the second cap 300 can be guided to the cap gripping mechanism 4 through the cap guiding mechanism 1. Therefore, the cap feeding and dispensing device is compatible with first caps 200 and second caps 300 that have significant height differences. Thus, the cap feeding and dispensing device can achieve the co-line production of caps of various heights. When producing caps of different heights, it is not necessary to replace the entire device, saving costs and reducing the time required for changeover between different caps.

[0041] To increase the conveying efficiency of the first cover 200 or the second cover 300 to the cover guide mechanism 1, both the first cover feeding mechanism 21 and the second cover feeding mechanism 22 are provided with a second conveying body 211. The second conveying body 211 extends along the first direction and is spaced apart from the straight section 2121, with its lower end connected to the horizontal conveying section 2123. In one embodiment of the invention, when the cover enters the second conveying body 211, the central axis of the cover is parallel to the first direction, and the cover falls straight down in the second conveying body 211. The friction between the cover and the side walls of the second channel 2110 is small, and the speed is relatively fast. By adding a separate channel for conveying the cover, the cover can be selectively conveyed from the first channel 2120 or the second channel 2110, thereby improving the conveying efficiency.

[0042] Optionally, the second conveyor 211 includes a first mounting member 2111, a tube 2112, and a support frame 2113. The tube 2112 is located on the outer periphery of the guide cover mechanism 1. The first mounting member 2111 connects the tube 2112 and the guide cover mechanism 1. The support frame 2113 is mounted on the horizontal conveying section 2123. The tube 2112 extends along a first direction and is connected to the support frame 2113. The support frame 2113 supports the tube 2112 and has a fixed channel communicating with the horizontal conveying section 2123 and the tube 2112. The first cover 200 or the second cover 300 falls from the tube 2112 into the horizontal conveying section 2123 through the fixed channel. The tube 2112 of the second conveyor 211 is limited to the outer periphery of the guide cover mechanism 1 by the first mounting member 2111 and is fixed above the horizontal conveying section 2123 of the first conveyor 212 by the support frame 2113. Preferably, the tube 2112 is a circular tube. The inner diameter of the tube 2112 of the first cap feeding mechanism 21 is slightly larger than the diameter of the first cap 200, so that the first cap 200 is conveyed within the tube 2112 of the first cap feeding mechanism 21. Similarly, the inner diameter of the tube 2112 of the second cap feeding mechanism 22 is slightly larger than the diameter of the second cap 300, so that the second cap 300 is conveyed within the tube 2112 of the second cap feeding mechanism 22. The support frame 2113 can be a frame structure, including two side plates and a top plate. The side plates can be fixed to the outside of the horizontal conveying section 2123, and the top plate is used to connect to the tube 2112. The top plate has a fixing hole communicating with the tube 2112, so that the first cap 200 or the second cap 300 can pass through the fixing hole and fall into the horizontal conveying section 2123 of the first conveying body 212. Both side plates are equipped with locking feet, which can be used to fix the bottom plate 121 or pad 124 below to support the tube body 2112.

[0043] Furthermore, to ensure that the first cap 200 or the second cap 300 is delivered to the cap guiding mechanism 1, the cap feeding mechanism 2 also includes an air blowing assembly 23, which is located in the turning section 2122 and is positioned towards the flat delivery section 2123. The first cap 200 or the second cap 300 falls from the tube 2112 into the flat delivery section 2123 through a fixed channel, and enters the cap guiding mechanism 1 through the air thrust of the air blowing assembly 23.

[0044] Reference Figure 1 , Figure 2 and Figure 4As shown, the second cap feeding mechanism 22 also includes a second mounting member 2124. One end of the second mounting member 2124 is disposed on the straight section 2121, and the other end extends along the second direction to connect with the tube body 2112 or with the cap guiding mechanism 1. The second mounting member 2124 is installed on the top of the straight section 2121 or on the outside of the straight section 2121, and is connected to the tube body 2112 to install the first conveyor 212 onto one side of the second conveyor 211, and is connected to the cap guiding mechanism 1 through the second conveyor 211, thereby being installed on the outer periphery of the cap guiding mechanism 1.

[0045] Preferably, the turning section 2122 is arc-shaped. After the first cover 200 or the second cover 300 enters from the straight section 2121, it falls straight into the turning section 2122. To ensure that the first cover 200 or the second cover 300 is not easily stuck in the turning section 2122, the cover feeding mechanism 2 also includes an air blowing assembly 23. The air blowing assembly 23 is located in the turning section 2122 and is arranged in the direction of the flat feeding section 2123. The first cover 200 or the second cover 300 is conveyed in the first conveying body 212. After the first cover 200 or the second cover 300 passes through the turning section 2122 from a horizontal state, it becomes an upright state and is then pushed into the cover guiding mechanism 1 by the air blowing assembly 23.

[0046] The air blowing assembly 23 is movably mounted on the turning section 2122. Specifically, the air blowing assembly 23 includes a third mounting member installed on the turning section 2122, and also includes an air blowing element and a locking fastener. The air blowing element is mounted on the third mounting member via the locking fastener. The third mounting member has an arc-shaped adjustment groove, the curvature of which can be adapted to the curvature of the turning section 2122. By tightening or loosening the locking fastener, the air blowing element can be assembled onto the third mounting member or the position of the third mounting member can be adjusted.

[0047] Reference Figure 5 and Figure 8 As shown, there can be multiple air blowing components. The air outlets of the air blowing components are positioned at the turning section 2122 facing the flat delivery section 2123, so that the first cover 200 or the second cover 300 is blown from the turning section 2122 to the guide cover mechanism 1 by the air thrust of the air blowing components. In one embodiment, there are two air blowing components, which are spaced apart at the third mounting member, and the air outlets of the two air blowing components face the flat delivery section 2123. The air blowing components are existing and can be connected to an external air source.

[0048] Optionally, the cover guiding mechanism 1 includes a frame 11, a cover assembly 12, and a cover dispensing plate 13. The cover assembly 12 is detachably mounted on the frame 11. One end of the cover assembly 12 is adjacent to any of the cover feeding mechanisms 2, and the other end is connected to the cover gripping station. The cover assembly 12 extends around the outer periphery of the cover dispensing plate 13 and is spaced apart from the outer periphery of the cover dispensing plate 13. There is a guide channel between the cover assembly 12 and the cover dispensing plate 13 for the cover to pass through. The cover dispensing plate 13 rotates on the frame 11, and multiple covers enter the cover dispensing plate 13 and can be conveyed one by one to the cover gripping station along with the cover dispensing plate 13. The outer edge of the cover dispensing plate 13 has several slots 131 facing the cover plate 122. The covers conveyed by the cover feeding mechanism 2 can enter any one of the slots 131 and move with the cover dispensing plate 13. Specifically, the cap is blown from the flat conveyor section 2123 to the cap distribution plate 13 by the air blowing assembly 23, and enters the clamping slot 131. The cap distribution plate 13 rotates, driving the cap to be conveyed to the cap gripping station. Furthermore, all the edges of the clamping slots 131 are set with arcs to make a smooth transition, so that the cap can transition from the clamping slot 131 to the cap gripping station by inertia.

[0049] When the first cover 200 or the second cover 300 moves with the cover-separating plate 13, in order to ensure that the first cover 200 does not detach from the cover-separating plate 13 and to ensure that the first cover 200 or the second cover 300 enters the cover-grabbing station, a cover-protecting assembly 12 is provided on the outer periphery of the cover-separating plate 13.

[0050] Reference Figure 2 As shown, the cover assembly 12 includes a base plate 121, a cover plate 122, and a pressure plate 123. A frame 11 is mounted on the base plate 121. Cover plates 13 are spaced apart above the base plate 121. The cover plate 122 and pressure plate 123 are located above the base plate 121 and are arranged sequentially along a first direction. The cover moves within the space between the base plate 121 and the pressure plate 123 and is conveyed to the cover-grabbing station. Figure 2 and Figure 3 As shown, in one embodiment, the pressure plate 123 and the base plate 121 limit the cover in the vertical direction, and the cover plate 122 and the cover plate 13 limit the cover in the lateral direction, so that the cover can only be conveyed along the motion trajectory guided by the cover guide mechanism 1, thereby ensuring that the cover is accurately conveyed to the cover gripping station.

[0051] In order to facilitate the replacement of the appropriate cover plate 13 according to the first cover 200 or the second cover 300, the cover plate 13 has multiple cover units, which are spliced ​​together to form a circular turntable, and all cover units are provided with a snap-fit ​​131.

[0052] In one embodiment, when switching from producing the first cap 200 to producing the second cap 300, multiple cap sub-units can be detached from the frame 11 and replaced with thicker cap sub-units, correspondingly, such as... Figures 10 to 13 As shown, the cover plate 122 of the cover assembly 12 needs to be replaced with a thicker cover plate 122 to cooperate with the cover distribution plate 13 to limit the second cover 300, thereby ensuring that the second cover 300 can be smoothly conveyed in the cover guide mechanism 1. When producing covers of different heights, it is not necessary to replace the entire device. Only the cover plate 122, the cover distribution plate 13 and the cover gripping head 41 in the cover gripping mechanism 4 need to be replaced. Then, the pad plate 124 can be installed or removed accordingly to complete the production changeover of different covers. It is not necessary to replace the entire cover guide mechanism 1 and the cover gripping mechanism 4, which greatly reduces the time for production changeover of different covers.

[0053] Furthermore, referring to Figure 12 and Figure 13 As shown, the protective cover plate 122 has a stepped structure 1220 on the side facing the cover plate 13 to limit the constriction structure of the second cover 300 and ensure that the second cover 300 is smoothly conveyed in the guide cover mechanism 1.

[0054] Optionally, the cover assembly 12 also includes a pad 124, which is located above the base plate 121 and forms a limiting channel with the pressure plate 123 for the movement of the cover. The pad 124 extends below the first cover feeding mechanism 21, which is mounted on the pad 124.

[0055] Since the height of the first cover 200 is less than the height of the second cover 300, and the position of the pressure plate 123 remains unchanged, a pad 124 needs to be installed below the cover plate 122 to limit the vertical movement of the first cover 200 through the pad 124 and the pressure plate 123, ensuring the stability of the first cover 200 during transport by the cover guide mechanism 1. The pad 124 may include a first pad structure and a second pad structure. The first pad structure is installed below the first cover feeding mechanism 21, and the second pad structure is installed above the base plate 121. When switching production to the second cover 300, only the second pad structure needs to be replaced and disassembled, without disassembling the first pad structure and the first cover feeding mechanism 21, greatly shortening the changeover time.

[0056] Optionally, the cap feeding and dispensing device further includes a cap blocking mechanism 3, which is located between the cap feeding mechanism 2 and the cap guiding mechanism 1. The cap blocking mechanism 3 has a pressing member 31 that moves in a first direction to press the cap located below the pressing member 31. The pressing member 31 can be configured as a pressing block structure.

[0057] Furthermore, referring to Figure 6 and Figure 9As shown, the pressure plate 123 is provided with a through hole 1230 corresponding to the pressure member 31 to allow the pressure member 31 to move. The cover mechanism 3 also includes a driving member, which is used to drive the pressure member 31 to rise and fall. The driving member can be a cylinder or a motor. The driving member is located above the pressure plate 123.

[0058] Optionally, the cap feeding and dispensing device also includes a cap gripping mechanism 4 and a pull rod mechanism 5. The cap gripping mechanism 4 is located on the frame 11 and at the cap gripping station. The cap guiding mechanism 1 also includes a rotating shaft 14. The rotation axis of the rotating shaft 14 extends along a first direction. The cap dispensing disc 13 is connected to the end of the rotating shaft 14 away from the frame 11. One end of the pull rod mechanism 5 is hinged to the top of the frame 11, and the other end is hinged to the cap gripping mechanism 4.

[0059] Reference Figure 2 , Figure 4 and Figure 7 As shown, the upper part of the rotating shaft 14 is connected to the frame 11 via a bushing. Two bearings are installed between the middle part of the rotating shaft 14 and the bushing. The middle part of the rotating shaft 14 is tapered and has a pin gear 141 installed thereon. The pin gear 141 is fixed to the rotating shaft 14 via a clamp and bolts. The pin gear 141 is driven by the drive shaft of the cover grabbing head 41. The cover grabbing head 41 rotates around the central axis of the cover grabbing mechanism 4, thereby driving the pin gear 141 to rotate around the center of the cover divider. The lower part of the rotating shaft 14 is provided with a tightening sleeve. A positioning plate 132 and a cover divider 13 are fixed to the outside of the tightening sleeve. The cover divider 13 is fixed to the positioning plate 132 with bolts. Because the rotation of the pin gear 141 drives the rotating shaft 14 and the cover divider 13 connected to it to rotate synchronously, it drives the first cover 200 or the second cover 300 to be sent synchronously to the bottom of the cover grabbing head 41.

[0060] Because the cap-grabbing mechanism 4 requires the installation of the cap-grabbing head 41, its overall height is relatively high. Therefore, the cap-grabbing mechanism 4 is fixed to one side of the guide cap mechanism 1 via a mounting bracket. Simultaneously, the top of the cap-grabbing mechanism 4 is connected to the frame 11 of the guide cap mechanism 1 via a pull rod mechanism 5. The pull rod mechanism 5, the mounting bracket, and the cap-grabbing mechanism 4 form a triangle, improving the stability of the cap-grabbing mechanism 4 and preventing significant shaking when gripping the first cap 200 or the second cap 300. The angle between the pull rod mechanism 5 and the top surface of the frame 11 is 45 degrees.

[0061] Furthermore, the cap feeding and dispensing device also includes a detection mechanism 6, which is designed on the frame 11 and located above the rotating shaft 14.

[0062] The detection mechanism 6 can be used to detect whether the first cap 200 or the second cap 300 has entered the filling machine. If the detection mechanism 6 detects that the first cap 200 or the second cap 300 has entered, the detection mechanism 6 can send a cap release signal to the corresponding cap blocking mechanism 3. If the detection mechanism 6 detects that neither the first cap 200 nor the second cap 300 has entered, the detection mechanism 6 can send a cap blocking signal to the cap blocking mechanism 3.

[0063] Reference Figure 1 , Figure 10 and Figure 11 As shown, during the production of the second cover 300, the second cover 300 is fed downwards from the first conveyor body 212. The turning section 2122 of the first conveyor body 212 has a certain curvature. The second cover 300, initially horizontal, becomes upright after passing through the turning section 2122, and then enters the cover-separating plate 13 under the thrust of the air blowing assembly 23. The second cover 300 passes through the limiting space between the cover plate 122 and the cover-separating plate 13. The cover-separating plate 13 can separate multiple second covers 300. Several latches 131 are provided on the outer edge of the cover-separating plate 13. The latches 131 have a smooth, rounded transition, and a stepped structure 1220 can be provided on the side of the latches 131 facing the second cover 300 to ensure smooth movement of the high cover during operation. The cover-separating plate 13 includes multiple cover-separating units. Generally, there are two cover-separating units. The joints between the cover-separating units have a rounded structure to improve the flatness after installation. Several washers are installed above the cover plate 122, and a pressure plate 123 is installed above the washers. The pressure plate 123 can prevent the second cover 300 from jumping or tilting during the conveying process of the cover tray 13. Bolts extend from the bottom of the cover plate 122 to connect and fix the cover plate 122, washers and pressure plate 123. The second cover 300 moves within the space formed by the cover plate 122, cover tray 13 and pressure plate 123 until it moves to the cover gripping station, where it waits to be gripped by the cover gripping head 41. A cylinder of the cover blocking mechanism 3 is installed above the pressure plate 123. The cylinder can be controlled by the detection mechanism 6 to start releasing the cover into the cover tray 13 at the corresponding station.

[0064] The cylinder is positioned before entering the cap-separating plate 13. When the cylinder drives the pressing component 31 upward, there is no resistance above the second cap 300, and the air-blowing assembly 23 starts blowing air to push the second cap 300 into the latch 131 of the cap-separating plate 13. The cap-separating plate 13 continues to rotate, and the closely arranged second caps 300 are separated at equal intervals and sent to the cap-grabbing station below the cap-grabbing head 41. When the detection mechanism 6 issues a cap-blocking signal, the cylinder of the cap-blocking mechanism 3 moves downward, and the pressing component 31 at the end of the cylinder applies downward pressure to the second cap 300 to prevent the second cap 300 from entering the cap-separating plate 13, while the air-blowing assembly 23 stops blowing air.

[0065] Reference Figures 1 to 6As shown, during the production of the first cap 200, the first cap feeding mechanism 21 is held at the outer periphery of the cap distribution plate 13. The protective cap plate 122 and the cap gripping head 41 are removed and replaced with suitable protective cap plates 122 and suitable cap gripping heads 41, and then the first pad plate 124 structure is installed. The first cap 200 continues to slide down via the first conveyor body 212, and the thrust of the auxiliary air blowing assembly 23 causes the first cap 200 to be conveyed to the slot 131 of the cap distribution plate 13.

[0066] Above the pressure plate 123, there is a cylinder for the cap-blocking mechanism 3. The piston rod of the cylinder is connected to the pressure member 31. When the cap-blocking mechanism 3 receives the cap-releasing signal sent by the detection mechanism 6, the cylinder moves upward and the pressure member 31 separates from the upper part of the first cap 200. The first cap 200 enters the cap-separating plate 13 under the air blowing action of the air blowing assembly 23. The first cap 200 moves on the pad plate 124. The cap-separating plate 13 separates multiple first caps 200 at equal distances and sends them one by one to the cap-grabbing station.

[0067] When the cover blocking mechanism 3 receives the cover blocking signal sent by the detection mechanism 6, the piston rod of the cylinder moves downward, and the pressing component 31 quickly presses down the first cover 200, so the first cover 200 cannot enter the cover plate 13, and the air blowing component 23 stops blowing air.
