For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0034] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0035] Referring to Figures 1 to 9 As shown, a cup dropping device includes a cage assembly 1, a cup fork assembly 2 and a cup dropping assembly 3 which are arranged in sequence from top to bottom. The cage assembly 1 includes a plurality of cages 11 arranged horizontally. The upper part of the cage is provided with a cage inlet 111, and the lower part is provided with a cage outlet 112. The cage is provided with a longitudinal guiding member 12 and a transverse guiding member 13. Among them, the longitudinal guiding member 12 includes longitudinal guiding members arranged on both longitudinal sides of the cage. The longitudinal guiding members are driven by a longitudinal adjusting driver to move longitudinally. The transverse guiding member 13 includes transverse guiding members arranged on both transverse sides of the cage. The transverse guiding members are driven by a transverse adjusting driver to move transversely. The size of the cage is adjusted by the cooperation of the longitudinal guiding members and the transverse guiding members, and the cup is guided to fall from the cage.

[0036] Among them, the cage assembly 1 is provided with an upper cage plate and a lower cage plate that are parallel up and down. The upper cage plate and the lower cage plate are generally rectangular. There are column supports arranged therebetween, specifically distributed at the four corners of the rectangle and the transverse middle positions of the longitudinal sides. By arranging a row of cage inlets 111 on the upper cage plate and correspondingly arranging a row of cage outlets 112 on the lower cage plate, a plurality of cages 11 arranged horizontally are formed. Therefore, the surrounding sides of the cage are not provided with closed side walls, but the size of the cage is adjusted by the cooperation of the transverse guiding members and the longitudinal guiding members, and the cup is guided to fall from the cage.

[0037] As an implementation manner, as Figures 2 to 4As shown, the longitudinal guide member includes at least one guide rod 121. In order to simultaneously adjust the longitudinal guide members of a plurality of squirrel cages 11 arranged horizontally, the longitudinal adjustment driver includes a transverse connecting plate 122 connected to all the guide rods, a longitudinal slide rail 123 cooperating with the transverse connecting plate 122, and a longitudinal adjustment driving cylinder 124 for driving the transverse connecting plate 122 to longitudinally slide along the longitudinal slide rail 123. Moreover, an inclined or arc-shaped curved guide section can be provided at the upper part of the guide rod to guide the cup body into the squirrel cage. In this embodiment, two guide rods 121 are arranged side by side on one longitudinal side of each squirrel cage. Of course, only one guide rod 121 can also be arranged at the middle position on one longitudinal side. It can be understood that the longitudinal guide member can also be arranged in a plate-like structure, and the longitudinal adjustment driver can also use other linear driving devices such as an oil cylinder or an electric cylinder to drive the transverse connecting plate to longitudinally slide.

[0038] As an embodiment, the transverse guide member includes an upper hinge plate 131 and a lower hinge plate 132. The lower end of the upper hinge plate is hinged to the upper end of the lower hinge plate through an intermediate pin shaft. The upper end of the upper hinge plate is hinged to an upper pin shaft. The lower hinge plate is connected with a transverse moving member 133, and the lower end of the lower hinge plate is a free end and is not connected to other components. After the transverse moving member 133 moves transversely, the position of the intermediate pin shaft changes, and at the same time, the inclination angle of the upper hinge plate 131 changes.

[0039] In order to realize the simultaneous adjustment of the lateral guides of several squirrel cages 11 arranged horizontally, the upper hinge plates of adjacent squirrel cages are hinged by the same upper pin shaft, and the upper pin shaft is freely arranged without being fixed to other components. The lower hinge plates on the adjacent sides of adjacent squirrel cages are respectively connected to a first lateral moving member and a second lateral moving member on the longitudinal two sides, and the moving directions of the first lateral moving member and the second lateral moving member are opposite. The upper pin shafts corresponding to the lateral outer sides of the two squirrel cages at both ends are hinged to the squirrel cages, and the corresponding two lower hinge plates are respectively connected to the first lateral moving member and the second lateral moving member on the longitudinal two sides. A lateral moving plate 134, namely a first lateral moving plate and a second lateral moving plate, is respectively arranged on the longitudinal two sides of the squirrel cage assembly. A plurality of first lateral moving members are connected to the first lateral moving plate, and a plurality of second lateral moving members are connected to the second lateral moving plate. A lateral adjustment driver is respectively arranged on the longitudinal two sides of the squirrel cage assembly. The lateral adjustment driver includes a lateral slide rail 135, a lateral slider slidably matched with the lateral slide rail, and a lateral adjustment driving cylinder 136 for driving the lateral slider to slide along the lateral slide rail. The first lateral moving plate and the second lateral moving plate are connected to the lateral slider of a corresponding lateral adjustment driver. The above technical solution can realize the synchronous adjustment of the two lateral guides on the lateral two sides of the squirrel cage, and the directions are opposite. No matter how it is adjusted, the middle part between the two lateral guides on the lateral two sides of the squirrel cage always corresponds to the middle position of the squirrel cage. Therefore, when the cup falls from the squirrel cage, it is also located at the middle position. In this way, when it continues to fall, it keeps facing the cup fork assembly 2 and the cup dropping assembly 3 directly below.

[0040] The above longitudinal slide rail 123, longitudinal adjustment driving cylinder 124, lateral slide rail 135, and lateral adjustment driving cylinder 136 are all arranged on the lower squirrel cage plate. Among them, the longitudinal slide rail 123 is fixed to the bottom surface of the lower squirrel cage plate, the longitudinal adjustment driving cylinder 124 is fixed to the longitudinal two sides of the lower squirrel cage plate through a cylinder fixing bracket, the lateral slide rail 135 is fixed to the upper surface of the lower squirrel cage plate, and the lateral adjustment driving cylinder 136 is fixed to the lateral two sides of the upper surface of the lower squirrel cage plate through a cylinder fixing bracket, and all can be fixed by screws.

[0041] It can be understood that the lateral guide can also adopt a structure similar to the guide rod or guide plate of the longitudinal guide, and its adjustment method can also adopt a method similar to that of the longitudinal guide, that is, two lateral adjustment drivers in the lateral two directions are used to correspondingly adjust the lateral guides on the lateral two sides of all squirrel cages.

[0042] As Figure 4 and Figure 5 shown, the cup fork assembly 2 includes a pair of upper cup forks 21 and a pair of lower cup forks 22 corresponding to each squirrel cage, and a cup body accommodating space is formed between a pair of upper cup forks 21 and a pair of lower cup forks 22 corresponding up and down. As Figure 6As shown, the upper cup forks 21 and the lower cup forks 22 are both provided with fork openings that cooperate with the side surface of the cup body. A plurality of pairs of upper cup forks are driven to open and close by an upper cup fork driver, and a plurality of pairs of lower cup forks are driven to open and close by a lower cup fork driver.

[0043] Since the shapes of the cup bodies are diverse, the common ones are round cups and square cups. In order to make the fork openings adapt to cup bodies of different shapes, such as Figure 6 As shown, the fork opening includes an arc-shaped groove 211 and transverse cutting fork surfaces 212 extending transversely arranged on both sides of the arc-shaped groove. Among them, the transverse cutting fork surfaces 212 can act on the side surface of the square cup, and the arc-shaped groove can cooperate with the outer arc of the round cup.

[0044] Furthermore, all the upper cup forks on one longitudinal side are arranged on the same first upper cup fork connecting plate, and all the upper cup forks on the other longitudinal side are arranged on the same second upper cup fork connecting plate. The upper cup fork driver is an upper cup fork driving cylinder. Each of the transverse two ends of the first upper cup fork connecting plate is connected to an upper cup fork driving cylinder 23, and each of the transverse two ends of the second upper cup fork connecting plate is connected to an upper cup fork driving cylinder 23. And the four upper cup fork driving cylinders 23 act simultaneously to achieve synchronous movement of the upper cup forks. All the lower cup forks on one longitudinal side are arranged under the same first lower cup fork connecting plate, and all the lower cup forks on the other longitudinal side are arranged under the same second lower cup fork connecting plate. The lower cup fork driver is a lower cup fork driving cylinder 24. Each of the transverse two ends of the first lower cup fork connecting plate is connected to a lower cup fork driving cylinder 24, and each of the transverse two ends of the second lower cup fork connecting plate is connected to a lower cup fork driving cylinder 24. And the four lower cup fork driving cylinders 24 act simultaneously to achieve synchronous movement of the lower cup forks.

[0045] The working principle of the cup fork assembly is as follows: First, a plurality of pairs of upper cup forks are driven to open by the upper cup fork driver, and a plurality of pairs of lower cup forks are driven to close by the lower cup fork driver. At this time, the cups falling from the cage assembly 1 enter the cup body accommodation space; then the upper cup forks are driven to close by the upper cup fork driver, so only one cup can enter the cup body accommodation space each time; finally, a plurality of pairs of lower cup forks are driven to open by the lower cup fork driver, and the cups in the cup body accommodation space fall. In this way, it circulates repeatedly to achieve the individual falling of the cups.

[0046] It can be understood that all the upper cup forks on one longitudinal side can also be directly an integral structure. All the lower cup forks on one longitudinal side can also be directly an integral structure without being connected by a cup fork connecting plate. All the upper cup forks and lower cup forks of the integral structure on each longitudinal side are correspondingly arranged on the cup fork driving beam 25. The cup fork driving beam is provided with cup fork driving guide sleeves 251. The cup fork assembly bracket includes transverse side plates on both sides. There are cup fork driving guide rods between the two longitudinal sides of the transverse side plates. The cup fork driving guide sleeves 251 are slidably connected with the cup fork driving guide rods.

[0047] Such as Figure 9As shown in the figure, the cup dropping assembly 3 includes a plurality of cup dropping support rods 31 corresponding to a plurality of mouse cages 11. The top of the cup dropping support rod is provided with a cup dropping tray 311, and the bottom end is arranged on a lifting bracket 32, and the lifting bracket 32 is driven by a lifting driver to lift and lower. After the lifting driver drives the lifting bracket 32 to rise, the cup fork assembly releases the cup, and the cup falls onto the cup dropping tray 311. Then the lifting driver drives the lifting bracket 32 to descend, and the cup is taken away.

[0048] In order to fix the cup on the cup dropping tray to prevent it from falling, the cup dropping tray 311 is a suction cup that can firmly adsorb the cup. A corresponding air path structure of the suction cup is designed. Among them, a lifting cross beam 321 and a lifting air pipe 322 are arranged side by side on the lifting bracket 32. An air passage that is connected up and down is arranged inside the cup dropping support rod. The upper end of the air passage is connected to the suction cup, the bottom end of the cup dropping support rod is arranged on the lifting cross beam, and the bottom end of the air passage is connected to a first air pipe joint 312. The lifting air pipe 322 is provided with a plurality of second air pipe joints 3221 corresponding to the plurality of first air pipe joints, and the first air pipe joint and the second air pipe joint are connected by a connecting air pipe. In this way, by only controlling the lifting air pipe 322, the air paths of the cup dropping trays of a plurality of cup dropping support rods can be uniformly controlled, and the consistent action of the cup dropping tray 311 can be realized.

[0049] As an implementation manner, the lifting driver includes a lifting transmission belt 33, a lifting driving block 323, and a lifting guide rod 3231. The lifting transmission belt 33 is driven by a transmission belt pulley, and the transmission belt pulley is driven by a lifting driving motor 331. A driven belt pulley and a tensioning belt pulley that cooperate with the lifting transmission belt are also provided. The above-mentioned lifting transmission belt 33 and the corresponding belt pulleys are arranged on the side of the machine frame, and the lifting driving motor 331 is installed on the top of the machine frame. The lifting transmission belt is fixed to the lifting driving block through a pressing plate. The lifting driving block is connected to the lifting bracket. The lifting driving block is provided with a guiding sleeve, and the guiding sleeve is in guiding cooperation with the lifting guide rod. It can be understood that the lifting driver can also adopt a cylinder, an oil cylinder, an electric cylinder, etc. to drive the lifting bracket 32 to lift and lower.

[0050] The above is only the specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
