Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, in particular to a bottle discharging device and packaging equipment. Background Art

[0002] In non-bottom-supported bottle conveying methods for liquid packaging equipment, after the bottle is capped and discharged from the capping machine, when the bottle is discharged using the bottle neck hanging and lifting method, the bottle discharge star wheel can be raised and lowered according to the height of the bottle to discharge the bottle onto the conveyor chain. Although this bottle discharge method can improve the compatibility of the bottle discharge star wheel and reduce the machining precision requirements of the bottle discharge star wheel components; however, because the bottle discharge star wheel is mostly a single-layer structure, during the conveying process, only the bottom guide plate of the bottle discharge guide plate can penetrate into the bottle discharge star wheel to guide the bottle transition to the conveyor chain, resulting in poor stability during the bottle discharge process and prone to bottle jams. Moreover, if the bottle discharge star wheel is set to multiple layers, the weight of the bottle discharge star wheel will increase, resulting in poor installation stability and strength. Utility Model Content

[0003] The purpose of the utility model is to provide a bottle discharging device and packaging equipment, which can reduce the weight of the star wheel assembly, improve the installation stability and installation strength of the star wheel assembly, and reduce the probability of bottles getting stuck during the bottle discharging process.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

The star wheel assembly is connected to the wheel seat through the connecting assembly. The star wheel assembly includes three parallel and spaced ribs, two of which cooperate to form a star wheel bottom plate, and the other rib serves as a star wheel top plate. The star wheel top plate is relatively spaced above the star wheel bottom plate. The conveyor chain is arranged on one side of the star wheel assembly, and the conveying channel on the conveyor chain is connected to the bottle discharge port of the star wheel assembly.

[0008] The guide assembly is fixedly arranged on the conveying chain, and the guide assembly includes a plurality of guide plates. The plurality of guide plates extend into the star wheel assembly at intervals along the height direction to guide the bottles from the star wheel assembly to the conveying chain.

[0009] As a further technical solution, the guide assembly further includes a mounting shaft, the plurality of guide plates are provided as a first guide plate and a second guide plate, the first end of the first guide plate and the first end of the second guide plate are both connected to the mounting shaft, and the first guide plate is fixedly connected to the conveyor chain;

[0010] The second end of the first guide plate extends to below the star wheel bottom plate and can guide the bottom end of the bottle. The second end of the second guide plate extends between the star wheel bottom plate and the star wheel top plate and can guide the middle part of the bottle.

[0011] As a further technical solution, a second end of the first guide plate and a second end of the second guide plate are both provided with a guide curved surface on one side close to the star wheel assembly.

[0012] As a further technical solution, at least one of the first end of the first guide plate and the first end of the second guide plate is adjustably connected to the mounting shaft along the axial direction of the mounting shaft.

[0013] As a further technical solution, the connecting assembly includes a pin and a threaded connector, and a connecting hole and a threaded hole are provided on the star wheel base plate. The pin passes through the connecting hole to be connected to the wheel seat, and the threaded connector passes through the threaded hole to be connected to the wheel seat.

[0014] As a further technical solution, a plurality of the connecting holes and the threaded holes are provided, a plurality of the pins and the threaded connectors are provided correspondingly, and the plurality of connecting holes and the plurality of threaded holes are alternately arranged along the circumferential intervals of the star wheel base plate.

[0015] As a further technical solution, a reinforcement plate is fixedly provided on the upper end surface of the wheel seat, and the star wheel base plate is fixedly connected to the reinforcement plate.

[0016] As a further technical solution, the star wheel assembly also includes at least one connecting shaft, the three ribs are fixedly sleeved on the connecting shaft through connecting holes, and the center lines of the three ribs are collinear with the axis of the wheel seat.

[0017] As a further technical solution, the star wheel assembly further includes a plurality of toggle plates, and a plurality of the toggle plates are arranged on the peripheral walls of the star wheel top plate and the star wheel bottom plate at intervals along their respective circumferential directions.

[0018] The packaging equipment comprises a capping machine and a bottle discharging device, wherein the outlet of the capping machine is connected to the bottle inlet of the bottle discharging device, and the outlet of the capping machine is higher than the bottle inlet.

[0019] Compared with the existing technology, the bottle discharging device and packaging equipment provided by the present invention have the following technical advantages:

[0020] 1. Because the star wheel bottom plate is composed of two ribs and the star wheel top plate is composed of one rib, when bottles are discharged by hanging the bottle neck and rotating and lifting, the center of gravity of the bottle is close to the bottom of the bottle. Therefore, the star wheel bottom plate and the star wheel top plate cooperate with each other. On the one hand, multiple guide plates extend into the star wheel assembly at intervals along the height direction, which can guide the bottles from the star wheel assembly to the conveyor chain, thereby improving the stability of the bottle during the discharge process and reducing the probability of the bottle getting stuck during the bottle discharge process. On the other hand, the star wheel bottom plate composed of two layers of ribs ensures the guidance effect on the bottom of the bottle, thereby reducing the probability of the bottle getting stuck. The star wheel top plate composed of a single layer of ribs ensures the guidance effect on the top of the bottle. At the same time, due to the reduction of one layer of ribs, the overall weight of the star wheel assembly can be reduced, thereby improving the installation stability and strength of the star wheel assembly.

[0021] 2. Since the bottle inlet of the bottle discharge device is connected to the outlet of the capping machine, and the outlet of the capping machine is higher than the bottle inlet, after the bottle is capped in the capping machine, as the capping machine operates, the bottle with the cap installed comes out of the outlet, then descends through the bottle inlet and enters the bottle discharge device. In the bottle discharge device, the star wheel bottom plate ensures the guidance effect on the bottom of the bottle, and the star wheel top plate ensures the guidance effect on the top of the bottle, thereby reducing the probability of the bottle getting stuck in the packaging equipment. The star wheel top plate composed of a single layer of ribs ensures the bottle discharge effect while minimizing the weight of the star wheel assembly and the packaging equipment.

[0041] Combine Figures 1 to 5As shown, the bottle discharging device provided in this embodiment can reduce the weight of the star wheel assembly 220, improve the installation stability and installation strength of the star wheel assembly 220, and reduce the probability of the bottle 10 being stuck during the bottle discharging process. Specifically, the bottle discharging device includes a wheel base 100, a bottle discharging mechanism 200 and a guide assembly 300; the bottle discharging mechanism 200 includes a connecting assembly 210, a star wheel assembly 220 and a conveying chain 230. The star wheel assembly 220 is connected to the wheel base 100 through the connecting assembly 210. The star wheel assembly 220 includes three parallel and spaced ribs 221, two of which cooperate to form a star wheel bottom plate, and the other rib 221 serves as a star wheel top plate. The star wheel top plate is relatively spaced above the star wheel bottom plate. The conveying chain 230 is arranged on one side of the star wheel assembly 220, and the conveying channel on the conveying chain 230 is connected to the bottle outlet of the star wheel assembly 220; the guide assembly 300 is fixedly arranged on the conveying chain 230, and the guide assembly 300 includes a plurality of guide plates, which extend into the star wheel assembly 220 at intervals along the height direction to guide the bottle 10 from the star wheel assembly 220 to the conveying chain 230.

[0042] Since the star wheel bottom plate is composed of two ribs 221 and the star wheel top plate is composed of one rib 221, when the bottle 10 is discharged by hanging the bottle neck and rotating and lifting, the center of gravity of the bottle 10 is close to the bottom of the bottle 10. Therefore, the star wheel bottom plate and the star wheel top plate cooperate with each other. On the one hand, multiple guide plates extend into the star wheel assembly 220 at intervals along the height direction, which can guide the bottle 10 from the star wheel assembly 220 to the conveyor chain 230, thereby improving the stability of the bottle 10 during the bottle discharging process and reducing the probability of the bottle 10 getting stuck during the bottle discharging process. On the other hand, the star wheel bottom plate composed of the double-layer ribs 221 ensures the guiding effect on the bottom of the bottle 10 to reduce the probability of the bottle getting stuck. The star wheel top plate composed of the single-layer rib 221 ensures the guiding effect on the top of the bottle 10. At the same time, due to the reduction of one layer of rib 221, the overall weight of the star wheel assembly 220 can be reduced, thereby improving the installation stability and installation strength of the star wheel assembly 220.

[0043] Preferably, the guide assembly 300 also includes a mounting shaft 310, and multiple guide plates are provided as a first guide plate 320 and a second guide plate 330. The first end of the first guide plate 320 and the first end of the second guide plate 330 are both connected to the mounting shaft 310, and the first guide plate 320 is fixedly connected to the conveyor chain 230; the second end of the first guide plate 320 extends to the bottom of the star wheel bottom plate and can guide the bottom end of the bottle 10, and the second end of the second guide plate 330 extends between the star wheel bottom plate and the star wheel top plate and can guide the middle of the bottle 10.

[0044] In addition, in this embodiment, the width of the first guide plate 320 is greater than the width of the second guide plate 330, and a plurality of connection holes are provided at intervals on a side of the first guide plate 320 near the star wheel assembly 220. A plurality of connecting bolts pass through the corresponding connecting holes to securely connect the first guide plate 320 to the conveyor chain 230, thereby connecting the guide assembly 300 to the conveyor chain 230. This arrangement further improves the connection strength and stability of the guide assembly 300 when connected to the conveyor chain 230, while preventing interference between the connecting bolts and the bottles 10 being guided.

[0045] Combine Figure 3 and Figure 5 As shown, in this embodiment, since the star wheel assembly 220 is composed of a star wheel bottom plate and a star wheel top plate, two guide plates are correspondingly provided, namely a first guide plate 320 and a second guide plate 330. When the guide assembly 300 is connected to the conveyor chain 230 via the mounting shaft 310, the second end of the first guide plate 320 can guide the bottom end of the bottle 10, and the second end of the second guide plate 330 can guide the middle of the bottle 10, thereby ensuring the stability of the bottle 10 during the bottle discharge process and reducing the possibility of the bottle 10 getting stuck during the bottle discharge process.

[0046] In some other embodiments, the number of guide plates can be increased according to actual needs, for example, three guide plates can be provided. During the process of the bottle 10 being unloaded, the three guide plates guide the upper, middle and lower parts of the bottle 10 respectively.

[0047] Preferably, a second end of the first guide plate 320 and a second end of the second guide plate 330 are both provided with a guide curved surface on one side close to the star wheel assembly 220 .

[0048] Specific combination Figure 5 As shown, since most bottles 10 are cylindrical, with a small portion having at least one curved surface, the first and second guide plates 320 and 330 are correspondingly provided with curved guiding surfaces. These curved surfaces curve away from the axis of the star wheel assembly 220 to further enhance the guiding effect of the first and second guide plates 320 and 330 on the bottles 10, thereby further reducing the probability of bottles 10 becoming stuck during the bottle removal process. Furthermore, using cylindrical bottles 10 as an example, the curvature of the curved guiding surface on the first guide plate 320 corresponds to the cross-sectional diameter of the lower portion of the bottle 10, while the curvature of the curved guiding surface on the second guide plate 330 corresponds to the cross-sectional diameter of the upper portion of the bottle 10, further enhancing the guiding effect on the bottles 10.

[0049] In other embodiments, flexible members may be provided on both the curved guide surfaces of the first guide plate 320 and the second guide plate 330. This reduces the probability of bottles 10 getting stuck during the bottle dispensing process while also minimizing scratching of the outer walls of the bottles 10 by the first and second guide plates 320 and 330, thereby ensuring the aesthetics of the bottles 10.

[0050] Preferably, at least one of the first end of the first guide plate 320 and the first end of the second guide plate 330 is adjustably connected to the mounting shaft 310 along the axial direction of the mounting shaft 310 .

[0051] With such arrangement, during the bottle discharging process, the distance between the first guide plate 320 and the second guide plate 330 can be adjusted according to the height of the bottles 10 being guided, so as to ensure the guiding effect for bottles 10 of different specifications and improve the applicability of the guide assembly 300 and the bottle discharging device. The connection mode in which the first guide plate 320 and the second guide plate 330 are adjustably connected to the mounting shaft 310 can be set as follows: threaded holes are provided at the first ends of the first guide plate 320 and the first ends of the second guide plate 330, the mounting shaft 310 is set as a threaded rod, the first guide plate 320 and the second guide plate 330 are threadedly connected to the threaded rod through their respective threaded holes, and the distance between the first guide plate 320 and the second guide plate 330 is changed by screwing the corresponding guide plates; or, the first ends of the first guide plate 320 and the first ends of the second guide plate 330 are fixedly connected to the mounting shaft 310, the mounting shaft 310 is set as a telescopic rod, and the distance between the first guide plate 320 and the second guide plate 330 is changed by adjusting the telescopic amount of the telescopic rod itself; the connection mode in which the first guide plate 320 and the second guide plate 330 are adjustably connected to the mounting shaft 310 is not limited to this, and can be set according to actual conditions in other embodiments.

[0052] Preferably, the connecting assembly 210 includes a pin 211 and a threaded connector 212. A connecting hole and a threaded hole are provided on the star wheel base plate. The pin 211 passes through the connecting hole to be connected to the wheel seat 100, and the threaded connector 212 passes through the threaded hole to be connected to the wheel seat 100.

[0053] Combine Figure 1 and Figure 2 As shown, the threaded connector 212 is used to connect the star wheel assembly 220 to the wheel seat 100, and the pin 211 is used to withstand the torsional force during the rotation of the star wheel assembly 220. In this way, the torsional force borne by the threaded connector 212 can be reduced, thereby improving the connection effect of the star wheel assembly to the wheel seat 100 and extending the service life of the threaded connector 212, thereby extending the service life of the bottle discharging device.

[0054] Furthermore, there are multiple connection holes and threaded holes, and multiple pins 211 and threaded connectors 212 are correspondingly provided. The multiple connection holes and the multiple threaded holes are alternately arranged along the circumference of the star wheel base plate. Figure 1 As shown, this arrangement further enhances the connection strength and stability of the star wheel assembly after it is connected to the wheel seat 100 through the cooperation of multiple pins 211 and multiple threaded connectors 212. In this embodiment, three connecting holes and three threaded holes are provided, with three pins 211 and three threaded connectors 212 provided, and the three connecting holes and three threaded holes are arranged alternately along the circumference of the star wheel base plate. The number of connecting holes and threaded holes provided is not limited to this number; in other embodiments, the number of connecting holes and threaded holes may be appropriately increased or decreased based on actual conditions.

[0055] Preferably, a reinforcing plate 110 is fixedly provided on the upper end surface of the wheel seat 100, and the star wheel bottom plate is fixedly connected to the reinforcing plate 110. Figure 2 As shown, the reinforcing plate 110 fixedly connected to the upper end surface of the wheel seat 100 can increase the connection area between the star wheel base plate and the wheel seat 100, thereby further improving the connection strength and connection stability of the star wheel assembly 220 to the wheel seat 100, thereby ensuring the stability of the bottle 10 during the bottle-out process, and reducing the probability of the bottle 10 getting stuck during the bottle-out process.

[0056] Preferably, the star wheel assembly 220 further includes at least one connecting shaft 222 , and the three ribs 221 are fixedly sleeved on the connecting shaft 222 through connecting holes, and the center lines of the three ribs 221 are collinear with the axis of the wheel seat 100 .

[0057] Combine Figure 1 and Figure 4 As shown, in this embodiment, six connecting shafts 222 are provided, and the six connecting shafts 222 are evenly spaced around the axis of the star wheel assembly 220, ensuring the connection strength and connection stability between the star wheel bottom plate and the star wheel top plate while ensuring the concentricity of the star wheel bottom plate and the star wheel top plate, thereby further improving the extradition effect on the bottle 10.

[0058] Preferably, the star wheel assembly 220 further includes a plurality of toggle plates 223, and a plurality of toggle plates 223 are provided on the peripheral walls of the star wheel top plate and the star wheel bottom plate at intervals along their respective circumferential directions. Figure 1 and Figure 4 As shown, as the star wheel assembly 220 rotates, a plurality of shifting plates 223 spaced apart on the peripheral walls of the star wheel top plate and the star wheel bottom plate are driven to rotate, thereby shifting the bottles 10 to improve the bottle discharging efficiency and effect.

[0059] The packaging equipment includes a capping machine 400 and a bottle discharging device. The outlet of the capping machine 400 is connected to the bottle inlet of the bottle discharging device, and the outlet of the capping machine 400 is higher than the bottle inlet.

[0060] Since the bottle inlet of the bottle discharging device is connected to the outlet of the capping machine 400, and the outlet of the capping machine 400 is higher than the bottle inlet, after the bottle 10 is capped in the capping machine 400, as the capping machine 400 operates, the bottle 10 with the cap installed gradually descends after exiting the outlet and enters the bottle discharging device from the bottle inlet. In the bottle discharging device, the star wheel bottom plate ensures a guiding effect on the bottom of the bottle 10, and the star wheel top plate ensures a guiding effect on the top of the bottle 10, thereby reducing the probability of the bottle 10 getting stuck in the packaging equipment. In addition, by providing the star wheel top plate composed of a single-layer rib plate 221, the weight of the star wheel assembly 220 and the packaging equipment is minimized while ensuring the bottle discharging effect.

[0061] In some other embodiments, the outlet of the capping machine 400 can also be set to be lower than the bottle inlet. After the bottle 10 is capped in the capping machine 400, as the capping machine 400 operates, the bottle 10 with the cap installed gradually rises after coming out of the outlet and enters the bottle discharge device from the bottle inlet.

[0062] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
