Description

Technical Field

[0001] This invention relates to a bottle outlet device for a blow molding machine, and more particularly to a dual-duct bottle outlet device for a rotary blow molding machine. Background Technology

[0002] In the field of automated beverage filling technology, after the PET blow molding machine outputs the bottles, they need to be sent to the filling machine for beverage filling. However, in existing production lines, each PET blow molding machine can only supply PET bottles to one filling machine, meaning that each production line can only fill one type of beverage. It is impossible to configure two filling machines for one blow molding machine to achieve simultaneous filling of two beverages, which greatly increases the investment cost of production line equipment and filling efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the problem that existing blow molding machines can only supply PET bottles to one filling machine, making it impossible to fill two beverages simultaneously. The invention provides a rotary blow molding machine dual-air duct bottle outlet device with high filling efficiency, low equipment cost, and high stability.

[0004] The objective of this invention can be achieved using the following technical solutions:

[0005] A rotary blow molding machine with dual air duct bottle outlet device, comprising:

[0006] A robotic arm used to grip bottles;

[0007] The first blowing device is used to blow the bottle toward the first filling machine;

[0008] The second blowing device is used to blow the bottles toward the second filling machine;

[0009] A bottle-pulling device is used to push a bottle into the input end of the first blowing device or the input end of the second blowing device;

[0010] The lane switching device is used to control the movement of the bottle toward the input end of the first blowing device or the front transition channel of the second blowing device;

[0011] The system includes multiple robotic arms, which are distributed and rotate circumferentially. The output end of the front transition channel is connected to the input end of the second blowing device. The robotic arms drive the bottles to rotate towards the input end of the first blowing device and the front transition channel of the second blowing device. When the separation switch device closes the front transition channel of the second blowing device, the bottle-pulling device pushes the bottles delivered by the robotic arms into the input end of the first blowing device. When the separation switch device opens the front transition channel of the second blowing device, the bottle-pulling device pushes the bottles delivered by the robotic arms through the front transition channel into the input end of the second blowing device, thus achieving dual-channel bottle separation.

[0012] As a preferred embodiment, the robotic arm includes a turntable and grippers disposed on the turntable, wherein there are multiple grippers arranged along the circumferential direction of the turntable.

[0013] As a preferred embodiment, both the first and second blowing devices include a duct slide plate with grooves for guiding the sliding of the bottle, a hood mounted above the duct slide plate, and a fan for inputting airflow into the hood and blowing the bottle along the duct slide plate.

[0014] As a preferred embodiment, the bottle-removing device includes a first bottle-removing mechanism and a second bottle-removing mechanism. The first bottle-removing mechanism is located in front of the input end of the first blowing device, and the second bottle-removing mechanism is located in front of the input end of the second blowing device. When the channel switch device closes the front transition channel of the second blowing device, the first bottle-removing mechanism pushes the bottle that has moved to the input end of the first blowing device, causing the bottle to enter the groove of the air duct slide plate of the first blowing device. When the channel switch device opens the front transition channel of the second blowing device, the second bottle-removing mechanism pushes the bottle that has moved to the input end of the second blowing device, causing the bottle to enter the groove of the air duct slide plate of the second blowing device.

[0015] As a preferred embodiment, the first bottle-pulling mechanism includes a first rotating shaft located in front of the input end of the first blowing device, and a first bottle-pulling plate located on the first rotating shaft; when the first rotating shaft drives the first bottle-pulling plate to rotate, the channel switch device closes the front transition channel of the second blowing device, and the first bottle-pulling plate pushes the bottle into the input end of the first blowing device.

[0016] As a preferred embodiment, the second bottle-pulling mechanism includes a second rotating shaft located in front of the input end of the second blowing device, and a second bottle-pulling plate located on the second rotating shaft; when the second rotating shaft drives the second bottle-pulling plate to rotate, the channel switch device opens the front transition channel of the second blowing device, and the second bottle-pulling plate pushes the bottle into the input end of the second blowing device.

[0017] As a preferred embodiment, the lane switching device includes a third rotating shaft and a lane baffle disposed on the third rotating shaft; the third rotating shaft drives the lane baffle to swing, so that the lane baffle opens or closes the front transition channel of the second blowing device.

[0018] As a preferred embodiment, the dividing baffle is located at the entrance of the front transition channel of the second blowing device. When the dividing baffle opens the front transition channel of the second blowing device, the input end of the first blowing device is connected to the front transition channel of the second blowing device. When the dividing baffle closes the front transition channel of the second blowing device, the dividing baffle guides the bottle into the input end of the first blowing device.

[0019] As a preferred embodiment, the lane divider switch also includes a cam mechanism, which drives the third rotating shaft to rotate and thus drives the lane divider baffle to swing.

[0020] As a preferred embodiment, the cam mechanism includes a rotary disk with a cam slide, and a connector that is slidably fitted onto the cam slide at one end, with the other end of the connector connected to a third rotating shaft. When the rotary disk rotates, the rotary disk drives one end of the connector fitted into the cam slide to slide along the cam slide, thereby driving the third rotating shaft to swing.

[0021] As a preferred embodiment, the connector includes a pin and a connecting rod. One end of the pin is slidably fitted onto the cam slide, and the other end of the pin is fixedly connected to the third rotating shaft via the connecting rod.

[0022] Implementing this invention has the following beneficial effects:

[0023] 1. This invention enables one blow molding machine to supply bottles to two filling machines simultaneously, allowing the two filling machines to fill different beverages respectively. This greatly reduces the number of blow molding machines used, lowers equipment investment costs, and improves filling efficiency.

[0024] 2. The dividing baffle of the present invention is cleverly designed at the entrance of the front transition channel of the second blowing device. The dividing baffle opens the front transition channel of the second blowing device, allowing the bottle to be rotated by the robot arm through the front transition channel to the input end of the second blowing device. The dividing baffle also closes the front transition channel of the second blowing device, preventing the bottle from entering the front transition channel of the second blowing device and guiding the bottle along the edge of the dividing baffle into the input end of the first blowing device. The structure is simple and ingenious, and can quickly distribute the bottle into two air channels, thereby forming two separate rows of bottles that are transported to the first filling machine and the second filling machine respectively.

[0025] 3. This invention drives the third rotating shaft to oscillate through the rotation of a cam mechanism. This oscillation of the third rotating shaft coordinates with the oscillation of the first rotating shaft and the rotation angle of the second rotating shaft. When the transition channel is opened and closed, the first and second bottle-pulling mechanisms push the bottles into the corresponding input ends of the first and second air-blowing devices. This achieves synchronous driving of the first, second, and third rotating shafts, enabling dual-channel bottle separation. This structure eliminates the need for numerous sensors to monitor the working status and rotation angle of the first, second, and third rotating shafts. Instead, it uses the transmission ratio of a transmission mechanism for control, greatly improving operational stability. The transmission mechanism can be a gear transmission mechanism or a pulley transmission mechanism. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0037] Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This embodiment relates to a dual-channel bottle ejection device for a rotary blow molding machine, including a robotic arm 1 for gripping bottles, a first blowing device 2 for blowing bottles toward a first filling machine, a second blowing device 3 for blowing bottles toward a second filling machine, a bottle ejection device 4 for pushing bottles into the input end of the first blowing device 2 or the input end of the second blowing device 3, and a lane switching device 5 for controlling the movement of bottles toward the input end of the first blowing device 2 or the front transition channel 31 of the second blowing device 3.

[0038] Multiple robotic arms 1 are provided, and they are distributed and rotated in the circumferential direction. The output end of the front transition channel 31 is connected to the input end of the second blowing device 3. The robotic arms 1 drive the bottles to rotate towards the input end of the first blowing device 2 and the front transition channel 31 of the second blowing device 3. When the channel separation switch device 5 closes the front transition channel 31 of the second blowing device 3, the bottle pulling device 4 pushes the bottles conveyed by the robotic arms 1 into the input end of the first blowing device 2. When the channel separation switch device 5 opens the front transition channel 31 of the second blowing device 3, the bottle pulling device 4 pushes the bottles conveyed by the robotic arms 1 through the front transition channel 31 into the input end of the second blowing device 3, thereby realizing the dual-channel bottle separation.

[0039] The entire device of this invention is located between the blow molding machine and the filling machine. By employing this device, one blow molding machine can simultaneously supply bottles to two filling machines, enabling the two filling machines to fill different beverages respectively. This significantly reduces the number of blow molding machines required, lowers equipment investment costs, and improves filling efficiency. Specifically, during operation, multiple robotic arms 1 drive the bottles to rotate circumferentially. After the lane divider switch 5 closes the front transition channel 31 of the second blow molding device 3, when the bottle is rotated by the robotic arm 1 to the input end position of the first blow molding device 2, the bottle-pulling device 4 pushes the bottle delivered by the robotic arm 1 into the input end of the first blow molding device 2. After the lane divider switch 5 opens the front transition channel 31 of the second blow molding device 3, the bottle is rotated by the robotic arm 1 through the front transition channel 31 to the input end of the second blow molding device 3, and then the bottle-pulling device 4 pushes the bottle delivered by the robotic arm 1 into the input end of the first blow molding device 2. This structure is equipped with two blowing devices. By controlling the opening or closing of the front transition channel 31 of the second blowing device 3 through the channel switching device 5, and controlling the working state of the bottle pulling device 4, the bottles are distributed to the input ends of the first blowing device 2 and the second blowing device 3 for conveying, thereby forming two rows of bottles that are simultaneously conveyed to the filling machine. The structure is ingeniously designed and reduces the cost of equipment.

[0040] The robotic arm 1 includes a turntable 11 and multiple grippers 12 mounted on the turntable 11, arranged circumferentially along the turntable 11. The center of the turntable 11 is externally powered via a connecting shaft. During the rotation of the turntable 11, the turntable 11 drives the grippers 12 to rotate. When the channel switch closes the front transition channel 31 of the second air blowing device 3, the grippers 12 rotate the bottle, and the bottle is pushed into the input end of the first air blowing device 2 by the bottle-pulling device 4. When the channel switch opens the front transition channel 31 of the second air blowing device 3, the grippers 12 rotate the bottle to the input end of the second air blowing device 3, and then the bottle is pushed into the input end of the second air blowing device 3 by the bottle-pulling device 4.

[0041] Both the first air-blowing device 2 and the second air-blowing device 3 include an air duct slide plate 24 with a groove 23, an air shroud 25 mounted above the air duct slide plate 24, and a fan 26 for inputting airflow into the air shroud 25 and blowing the bottle along the groove 23 of the air duct slide plate 24. The inlet of the groove 23 of the first air-blowing device 2 is the input end of the device; similarly, the inlet of the groove 23 of the second air-blowing device 3 is the input end of the device. After the bottle is pushed into the groove 23, the fan 26 inputs airflow into the air shroud 25 and blows the bottle along the groove 23 of the air duct slide plate 24 towards the outlet of the groove 23.

[0042] like Figure 1 and Figure 4 As shown, the bottle-pulling device 4 includes a first bottle-pulling mechanism 41 and a second bottle-pulling mechanism 42. The first bottle-pulling mechanism 41 is located in front of the input end of the first blowing device 2, and the second bottle-pulling mechanism 42 is located in front of the input end of the second blowing device 3. When the channel switch device 5 closes the front transition channel 31 of the second blowing device 3, the first bottle-pulling mechanism 41 pushes the bottle that has moved to the input end of the first blowing device 2, causing the bottle to enter the groove 23 of the air duct slide plate 24 of the first blowing device 2. When the channel switch device 5 opens the front transition channel 31 of the second blowing device 3, the second bottle-pulling mechanism 42 pushes the bottle that has moved to the input end of the second blowing device 3, causing the bottle to enter the groove 23 of the air duct slide plate 24 of the second blowing device 3. The bottle that enters the groove 23 of the air duct slide plate 24 is conveyed towards the filling machine along the groove 23 under the blowing of the airflow.

[0043] The first bottle-removing mechanism 41 includes a first rotating shaft 411 located in front of the input end of the first blowing device 2, and a first bottle-removing plate 412 located on the first rotating shaft 411. When the first rotating shaft 411 drives the first bottle-removing plate 412 to rotate, the channel switch device 5 closes the front transition channel 31 of the second blowing device 3, and the first bottle-removing plate 412 pushes the bottle into the input end of the first blowing device 2. The second bottle-removing mechanism 42 includes a second rotating shaft 421 located in front of the input end of the second blowing device 3, and a second bottle-removing plate 422 located on the second rotating shaft 421. When the second rotating shaft 421 drives the second bottle-removing plate 422 to rotate, the channel switch device 5 opens the front transition channel 31 of the second blowing device 3, and the second bottle-removing plate 422 pushes the bottle into the input end of the second blowing device 3. As the robotic arm 1 continuously rotates the bottles towards the input end of the first blowing device 2 and the front transition channel 31 of the second blowing device 3, the channel divider switch 5 continuously opens and closes the front transition channel 31 of the second blowing device 3, causing the bottles delivered by the robotic arm 1 to be divided into two rows that enter the input end of the first blowing device 2 and the front transition channel 31 of the second blowing device 3 respectively. When the channel divider switch 5 closes the front transition channel 31 of the second blowing device 3, the first bottle-pulling plate 412 pushes the bottles delivered by the robotic arm 1 into the input end of the first blowing device 2. When the channel divider switch 5 opens the front transition channel 31 of the second blowing device 3, the robotic arm 1 moves the bottles through the front transition channel 31 to the input end of the second blowing device 3, and then the second bottle-pulling plate 422 pushes the bottles delivered by the robotic arm 1 into the input end of the second blowing device 3.

[0044] like Figures 1 to 3 As shown, the lane switching device 5 includes a third rotating shaft 51 and a lane-separating baffle 52 disposed on the third rotating shaft 51. The third rotating shaft 51 drives the lane-separating baffle 52 to swing, causing the lane-separating baffle 52 to open or close the front transition channel 31 of the second blowing device 3. The third rotating shaft 51 is externally powered. The lane-separating baffle 52 is disposed at the entrance of the front transition channel 31. By controlling the rotation direction and rotation angle of the third rotating shaft 51, the lane-separating baffle 52 can open and close the front transition channel 31. After the lane-separating baffle 52 opens the front transition channel 31, the robot arm 1 carries the bottle first into the entrance of the front transition channel 31, and then moves to the input end (entrance of the slide 23) of the second blowing device 3 and is pushed into the entrance of the slide 23 of the second blowing device 3 under the push of the second bottle-pulling plate 422.

[0045] The dividing baffle 52 is located at the entrance of the front transition channel 31 of the second air blowing device 3. When the dividing baffle 52 opens the front transition channel 31 of the second air blowing device 3, the input end of the first air blowing device 2 is connected to the front transition channel 31 of the second air blowing device 3. At this time, the robot arm 1 drives the bottle to rotate to the input end position of the second air blowing device 3, and then the bottle is pulled out from the robot arm 1 and pushed into the groove 23 of the air duct slide plate 24 of the second air blowing device 3 under the push of the bottle pulling device 4. When the dividing baffle 52 closes the front transition channel 31 of the second air blowing device 3, and the robot arm 1 drives the bottle to rotate to the connection between the input end of the first air blowing device 2 and the front transition channel 31 of the second air blowing device 3, the bottle is blocked by the dividing baffle 52 and cannot enter the input end of the second air blowing device 3. Under the guidance of the dividing baffle 52, the bottle is pushed into the input end of the first air blowing device 2 by the bottle pulling device 4. The dividing baffle 52 of this structure is cleverly designed at the entrance of the front transition channel 31 of the second blowing device 3. The dividing baffle 52 serves to open the front transition channel 31 of the second blowing device 3, allowing the bottle to be rotated by the robot arm 1 through the front transition channel 31 to the input end of the second blowing device 3. Furthermore, the dividing baffle 52 also serves to close the front transition channel 31 of the second blowing device 3, preventing the bottle from entering the front transition channel 31 of the second blowing device 3 and guiding the bottle along the edge of the dividing baffle 52 into the input end of the first blowing device 2. The structure is simple and ingenious, and can quickly distribute the bottles into two air channels, thereby forming two separate rows of bottles that are transported to the first filling machine and the second filling machine respectively.

[0046] like Figure 1 , Figure 2 and Figure 5As shown, the lane divider switch device 5 also includes a cam mechanism 53, which drives the third rotating shaft 51 to rotate and thus drives the lane divider baffle 52 to swing. The first rotating shaft 411, the second rotating shaft 421 and the cam mechanism 53 of the present invention are externally powered through a transmission mechanism 54; a single motor is used to simultaneously drive the first rotating shaft 411, the second rotating shaft 421 and the cam mechanism 53 to rotate through the transmission mechanism 54. This invention drives the third rotating shaft 51 to swing through the rotation of the cam mechanism 53. This swinging motion of the third rotating shaft 51 coordinates with the swinging motion of the first rotating shaft 411 and the rotation angle of the second rotating shaft 421. When the third rotating shaft 51 opens and closes the transition channel 31, the first bottle-pulling mechanism 41 and the second bottle-pulling mechanism 42 can push the bottles into the corresponding input ends of the first blowing device 2 and the second blowing device 3. This achieves synchronous driving of the first rotating shaft 411, the second rotating shaft 421, and the third rotating shaft 51, enabling dual-channel bottle separation. This structure eliminates the need for numerous sensors to detect the working state and rotation angle of the first rotating shaft 411, the second rotating shaft 421, and the third rotating shaft 51. Instead, it uses the transmission ratio of the transmission mechanism 54 for control, greatly improving operational stability. The transmission mechanism 54 is either a gear transmission mechanism or a pulley transmission mechanism.

[0047] The cam mechanism 53 includes a rotating disk 532 with a cam slide rail 531, and a connector 533, one end of which is slidably fitted into the cam slide rail 531. The other end of the connector 533 is connected to a third rotating shaft 51. When the rotating disk 532 rotates, the rotating disk 532 drives one end of the connector 533 fitted into the cam slide rail 531 to slide along the cam slide rail 531, thereby driving the third rotating shaft 51 to swing. The cam slide rail 531 and one end of the connector 533 are connected with a clearance fit, so that the connector 533 can slide relative to the rotating disk 532 within the cam slide rail 531.

[0048] The connecting component 533 includes a pin 534 and a connecting rod 535. One end of the pin 534 is slidably sleeved on the cam slide rail 531, and the other end of the pin 534 is fixedly connected to the third rotating shaft 51 via the connecting rod 535. As shown in the figure, the connecting rod has an L-shaped structure. One end of the L-shaped connecting rod is fixedly connected to the upper end of the pin 534, and the other end of the connecting rod 535 is fixedly connected to the third rotating shaft 51.

[0049] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
