Description
Technical Field
[0001] This invention relates to the technical field of glass pushing and transferring, and in particular to a glass bottle pushing device with a segmented push rod. Background Technology
[0002] The glass bottle pusher is a key piece of equipment in the glass bottle production line. Its core function is to stably and accurately push the glass bottles sent from the conveyor into the annealing furnace to eliminate the internal stress of the glass bottles.
[0003] For example, utility model patent application CN222389049U discloses a three-axis servo bottle pusher, including a frame, a longitudinal slide plate that can slide longitudinally along a horizontal plane on the frame, a longitudinal motor that drives the longitudinal slide plate to slide back and forth fixedly connected to the frame, a transverse slide plate that can slide laterally along a horizontal plane on the longitudinal slide plate, and a transverse motor that drives the transverse slide plate to slide back and forth fixedly connected to the longitudinal slide plate; by using separate longitudinal motor, transverse motor and lifting motor, the three bottle pushing actions are adjusted separately, and the three actions are precisely coordinated, so that the glass bottle is pushed into the annealing furnace quickly and smoothly, with high machine speed and stable glass bottle without tipping over.
[0004] However, the following defects were found: when the glass bottles are pushed and fed on the conveyor belt, the greater the friction between the conveyor belt and the bottom of the glass bottle, the greater the interaction force between the push rod and the glass bottle. The pushing force of the push rod will cause local pressure damage or scratch damage to the outer wall of the glass bottle that has been preliminarily heat-melted and formed, thus affecting the quality of the glass bottle shipment. How to reduce the interaction force between the push rod and the glass bottle in the bottle pushing operation has become an urgent technical problem to be solved. Summary of the Invention

[0020] Compared with the prior art, the present invention provides a glass bottle pushing device with a segmented pusher, which has the following beneficial effects: The glass bottle pushing device with a segmented pusher uses a non-contact pressure-reducing lifting mechanism to evacuate or inflate the glass bottle, so that the air pressure inside and above the glass bottle is lower than the atmospheric pressure at the bottom. Under the action of pressure difference, the atmosphere forms an upward and downward "pushing force" on the glass bottle, which can reduce the friction between the glass bottle and the conveyor belt, thereby reducing the force exerted by the pusher body on the glass bottle during the pushing and unloading operation, and reducing the damage rate during the pushing and unloading process. The non-contact pressure-reducing lifting mechanism avoids direct contact with the glass bottle, and can prevent other parts of the glass bottle from being bumped and damaged during the auxiliary lifting process.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.
[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] Example 1 Please refer to Figures 1-7A glass bottle pushing device with segmented push rods includes a frame 1, a pushing drive mechanism, and a bottle pushing mechanism mounted on the pushing drive mechanism. The bottle pushing mechanism includes a push rod body and a non-contact pressure reducing and lifting mechanism. The pushing drive mechanism provides moving power for the push rod body and the non-contact pressure reducing and lifting mechanism. The non-contact pressure reducing and lifting mechanism is used to reduce the friction between the glass bottle and the conveyor belt. The non-contact pressure reducing and lifting mechanism includes a lifting drive component 2 and a lifting frame 3 mounted on the lifting drive component 2, a main air pipe 4 fixedly mounted on the lifting frame 3, and multiple branch air pipes 5 evenly distributed on the main air pipe 4. Furthermore, the push-drive mechanism can employ a linear drive slide, which provides power for the push rod body and the non-contact pressure-reducing lifting mechanism to move vertically along the glass bottle conveying direction; the push-drive mechanism can also employ a two-dimensional mechanical slide, which provides power for the push rod body and the non-contact pressure-reducing lifting mechanism to move along the glass bottle conveying direction and perpendicular to the glass bottle conveying direction; the lifting drive component 2 can employ a telescopic cylinder and guide rods, with the telescopic cylinder providing power for the lifting frame 3 to rise and fall, and the lifting drive component 2 can also employ a mechanical slide or other equivalent components that drive the lifting frame 3 to move up and down. It should be noted that this invention is applicable to small-diameter constricted-neck bottles such as beer bottles, but not to large-diameter bottles such as wide-mouth bottles.
[0035] When the push drive mechanism uses a linear drive slide, the glass bottle will move laterally along the synchronous belt under the action of inertia. Relative sliding will occur between the glass bottle and the push rod body, which will cause scratches on the outer wall of the glass bottle. Although using a two-dimensional mechanical slide (i.e. the longitudinal motor and transverse motor drive structure disclosed in the utility model patent application CN222389049U, a three-axis servo pusher) can reduce the risk of scratching during the glass bottle feeding process, its structure is complex.
[0036] Therefore, the above solution has been further optimized. For details, please refer to [link / reference needed]. Figures 1-4The push drive mechanism includes a longitudinal slide 16 slidably mounted on the frame 1, a sliding drive 17 that provides power for the sliding of the longitudinal slide 16, a transverse slide 18 slidably mounted on the longitudinal slide 16, and a reset drive 23 for resetting the transverse slide 18. A guide ramp 19 is fixedly mounted on the frame 1, and a roller 20 that contacts one side of the inclined side of the guide ramp 19 is rotatably mounted on the transverse slide 18. Furthermore, a track is provided on the frame 1, the longitudinal slide 16 is slidably mounted on the track, a guide rod is provided on the longitudinal slide 16, and the transverse slide 18 is slidably mounted on the guide rod. The reset drive 23 is preferably a spring, which is sleeved on the guide rod. One end of the spring abuts against the transverse slide 18, and the other end of the spring abuts against the frame 1. The reset drive 23 can also be an electric cylinder, which is fixedly mounted on the frame 1. The output end of the electric cylinder extends to push the transverse slide 18 to reset. The reset drive 23 can also be a tension spring, with both ends of the tension spring hinged to the frame 1 and the transverse slide 18 respectively. When the transverse slide 18 moves laterally and longitudinally, the tension spring is stretched. When the sliding drive 17 drives the longitudinal slide 16 to reset, the tension spring contracts, and the transverse slide 18 automatically resets to its initial position. The sliding drive 17 is preferably a telescopic cylinder, with both ends of the telescopic cylinder hinged to the longitudinal slide 16 and the frame 1 respectively. The sliding drive 17 can also be a mechanical slide or other equivalent components that can drive the longitudinal slide 16 to slide. The push rod body and the non-contact pressure reducing and lifting mechanism are both fixedly mounted on the transverse slide 18.
[0037] Please refer to Figures 1-3 Specifically, it also includes a lifting platform 21, on which the frame 1 is fixedly installed; furthermore, the lifting platform 21 can be a scissor lift platform, or a hydraulic cylinder lift platform or other equivalent components that have a lifting drive effect on the frame 1; the lifting platform 21 and the sliding drive 17 are automatically controlled to start and stop by an external control system.
[0038] In this embodiment, the orifice diameter of the gas distribution pipe 5 is smaller than the mouth diameter of the glass bottle. A 1-3mm annular gap is left between the gas distribution pipe 5 and the mouth of the glass bottle. The air pressure entering the glass bottle at the annular gap is less than the air intake of the gas distribution pipe 5. The air intake of the gas distribution pipe 5 should preferably be more than 10 times the air intake at the annular gap. The gas distribution pipe 5 is a rigid pipe, such as a metal pipe. The main gas pipe 4 is connected to an external vacuum device. The gas distribution pipes 5 are used for the extraction of gas from the glass bottle. After the external vacuum device is activated, the air inside the glass bottle is extracted through each gas distribution pipe 5 and the main gas pipe 4. The air pressure inside the glass bottle is much lower than the air pressure outside the glass bottle. The external atmospheric pressure has a lifting effect on the glass bottle. The atmospheric pressure distributes the weight of the glass bottle, greatly reducing the friction between the bottle and the conveyor belt. The suction force exerted by the air distribution pipe 5 on the inside of the glass bottle should be less than or equal to the weight of the bottle to prevent relative sliding between the bottle and the push rod body after the bottle is lifted, thus avoiding scratches caused by the push rod body and preventing the bottle from tipping over due to instability during the pushing process. While suctioning out the internal air pressure of the glass bottle, some external cold air is allowed to enter the bottle through the annular seam to cool the inside of the bottle, thereby reducing the temperature and increasing the surface hardness of the bottle and reducing the amount of scratches when the bottle is pushed.
[0039] Please refer to Figure 5 The sliding driver 17 can push the longitudinal slide 16 to move longitudinally. At this time, the roller 20 is in contact with the inclined edge of the guide slope plate 19. Under the pushing action of the guide slope plate 19, the transverse slide 18 moves laterally while following the longitudinal movement of the longitudinal slide 16. The conveyor belt conveys the glass bottle at a speed of V1, the transverse movement speed of the push rod body on the transverse slide 18 is V2, and the longitudinal movement speed is V3; where V1=V2; the inclined angle of the inclined edge of the guide slope plate 19 is preferably 45°, at which time V1=V2=V3; that is, by adjusting the longitudinal pushing speed V3 of the sliding driver 17 on the longitudinal slide 16 to be equal to the conveyor belt conveying speed V1 of the glass bottle, the glass bottle and the conveyor belt can be kept relatively stationary in the conveyor belt conveying direction during the glass bottle being pushed and unloaded. The glass bottle will not slide relative to the push rod body during the unloading operation, thereby avoiding the push rod body from scratching the outer wall of the glass bottle, and further reducing the damage rate of the glass bottle during the pushing and unloading operation.
[0040] Furthermore, by employing a sliding actuator 17, in conjunction with the guide slope plate 19, synchronous lateral and longitudinal movement of the push rod body can be achieved. This design is simple in structure, saves equipment costs, and effectively reduces the failure rate during subsequent use of the equipment.
[0041] The lifting platform 21 can drive the frame 1 to move up and down. After pushing the glass bottles on the conveyor belt, the lifting platform 21 drives the frame 1 to move up until the bottom of the bottle pushing mechanism is higher than the glass bottles on the conveyor belt. The sliding driver 17 drives the longitudinal slide 16 to reset, and the transverse slide 18 is reset under the action of the reset drive 23, so that the bottle pushing mechanism returns to the initial position of the bottle pushing operation after crossing the glass bottles on the conveyor belt.
[0042] Example 2 For further optimization of the above solution, please refer to [link / reference]. Figures 6-8 A jet head 6 is installed at the end of the gas distribution pipe 5. The jet head 6 is equipped with multiple nozzles 7. The jet ends of the nozzles 7 are arranged radially toward the glass bottle. The multiple nozzles 7 are evenly distributed around the jet head 6. A bottle stopper 24 is provided on the jet head 6. An annular channel is formed between the bottle stopper 24 and the bottle mouth of the glass bottle. Furthermore, the central axis of the bottle stopper 24 coincides with the central axis of the bottle mouth of the glass bottle. The gap of the annular channel is 1-2mm. The outlet end of the nozzle 7 is flush with or higher than the bottle mouth of the glass bottle by 0-5mm. The two ends of the main gas pipe 4 are connected to an external air pressure pressurization device through flexible pipes. The external air pressure pressurization device can be an air pump or a high-pressure compressed air source to ensure the airflow velocity at the nozzle 7.
[0043] Pressurized airflow is forced into the main air pipe 4 by an external pressurizing device. This pressurized airflow passes through the distribution pipe 5, the jet nozzle 6, and the nozzle 7, and then exits radially along the mouth of the glass bottle. According to Bernoulli's principle, the high-speed airflow blows horizontally over the annular channel, creating a low-pressure zone within the annular channel. This high-speed airflow continuously draws air out of the bottle through jet entrainment, significantly reducing the internal pressure. As the air is drawn out of the glass bottle and the internal pressure decreases, the external atmospheric pressure pushes the bottle upwards from the bottom, causing it to be "sucked" up and down. This reduces the pressure of the glass bottle on the conveyor belt, thereby reducing the friction between the bottle and the conveyor belt. This reduces the interaction force between the pusher body and the glass bottle, thus lowering the bottle's height. The incidence of scratches on the outer wall; it should be noted that the upward thrust generated by the pressure difference between the inside and outside of the glass bottle should be less than the weight of the glass bottle itself. While "reducing the weight" of the glass bottle, it is necessary to prevent the glass bottle from directly detaching from the conveyor belt to ensure the stability of the glass bottle when it is pushed; the negative pressure generated above the bottle mouth can also accelerate the upward movement of airflow on the outer wall of the glass bottle, so as to further accelerate the heat dissipation of the glass bottle from the inside and outside, thereby accelerating the hardening of the outer wall of the glass bottle and reducing the scratches caused by the push rod body on the outer wall of the glass bottle; in addition, it should be noted that the lifting frame 3 is equipped with a baffle or shield (not shown in the figure) located between two adjacent jet heads 6 to reduce the mutual interference of the airflow ejected from the two adjacent jet heads 6.
[0044] For details, please refer to Figure 6The push rod body is provided with multiple spacer blocks 8 evenly distributed at equal intervals. On both sides of the spacer block 8, there are arc-shaped parts 9 that fit with the outer wall of the glass bottle. The corresponding arc-shaped parts 9 on two adjacent spacer blocks 8 form a semi-ring. The center of the semi-ring coincides with the central axis of a corresponding gas distribution pipe 5 on the upper part of the two spacer blocks 8.
[0045] The spacer block 8 can guide the glass bottle between two adjacent spacer blocks 8, so that the outer wall of the glass bottle contacts the arc-shaped part 9 on the two spacer blocks 8, so that the mouth of the glass bottle is exactly below the corresponding air distribution pipe 5. In this way, the glass bottle and the air distribution pipe 5 can be automatically aligned, so that the bottle stopper 24 on the jet head 6 can be smoothly inserted into the mouth of the glass bottle. Under the action of the spacer block 8, the spacing between each glass bottle is the same, and the glass bottles are neatly and equally spaced.
[0046] For details, please refer to Figure 6 An electric control valve 10 is installed on the gas distribution pipe 5, and multiple sensors 11 are installed on the push rod body. The multiple sensors 11 are located between two adjacent spacers 8. Furthermore, the sensors 11 are connected to the corresponding electric control valve 10 through an external control system (such as a DCS control system, PLC control system, etc.). The electric control valve 10 takes priority over the solenoid valve. The sensors 11 can be contact sensors, such as strain gauge pressure sensors or conductive rubber sensors. The sensors 11 and the electric control valve 10 can be conventional and known mature products on the market. The structure and control principle of the electric control valve 10 and the sensors 11 will not be described in detail here.
[0047] When the glass bottle contacts the arc-shaped part 9 on the spacer block 8, the sensor 11 contacts the bottle wall. The sensor 11 converts the pressure signal at the time of contact into an electrical signal and transmits it to the external control system. The external control system processes the signal and transmits it to the corresponding solenoid valve 10, causing the solenoid valve 10 to open and the corresponding jet head 6 to start jetting. This achieves automated control of the start and stop of the jet head 6. When the sensor 11 is not in contact with the glass bottle, the solenoid valve 10 is in the closed state, avoiding the jet head 6 from being in the jetting state for a long time, so as to reduce the waste of pressurized airflow.
[0048] The glass bottles conveyed by the conveyor belt are at a high temperature, while the temperature of the push rod body on the side closest to the glass bottle is significantly higher than the temperature of the side furthest from the glass bottle. The uneven heating of the front and back of the push rod body causes uneven expansion. Over time, the push rod body is prone to bending, which causes misalignment between the glass bottle and the corresponding air nozzle 6 at both ends of the push rod body. The bottle stopper 24 and the central axis of the glass bottle mouth are offset, affecting the force balance when the glass bottle is pumped or blown.
[0049] Therefore, the above solution has been further optimized; please refer to the following: Figure 9The push rod body includes multiple rod segments 12, multiple hinge pins 13, and multiple locking bolts 14. The end of the rod segment 12 is provided with an open shaft hole 15. The hinge pin 13 is inserted into the open shaft hole 15 at the end of two adjacent rod segments 12. The end of the rod segment 12 is provided with a threaded hole that passes through the opening of the open shaft hole 15. The locking bolt 14 is screwed into the threaded hole. Furthermore, two adjacent rod segments 12 are hinged together by the hinge pin 13. The hinge pin 13 is locked to the inner wall of the open shaft hole 15 by the locking bolt 14.
[0050] Specifically, rod segment 12, hinge pin 13, and locking bolt 14 are all made of cast iron.
[0051] The push rod body adopts a multi-segment 12 design to reduce the bending degree of a single segment 12, thereby effectively reducing the bending offset at both ends of the push rod body. When the push rod body bends, two adjacent segments 12 can be rotated around the corresponding hinge axis 13 to adjust them so that the segments 12 tend to be on the same horizontal line. After adjustment, the two segments 12 can be locked to the hinge axis 13 by locking bolts 14. The low coefficient of thermal expansion of cast iron further reduces the amount of bending caused by heat in the push rod body, so that the glass bottles pushed by the push rod body are aligned in a straight line.
[0052] Please refer to Figure 6 The rod segment 12 is provided with a slide rail 22, and the spacer block 8 is slidably installed on the slide rail 22. The spacer block 8 is screwed with a threaded set screw, and the spacer block 8 is locked to the slide rail 22 by the threaded set screw. Furthermore, the arc-shaped part 9 is detachably connected to the spacer block 8. The arc-shaped part 9 is made of a high-temperature resistant flexible material, such as high-temperature resistant silicone or high-temperature resistant fiber.
[0053] The spacer block 8 can be replaced according to the glass bottle with different outer diameter, and the distance between two adjacent spacer blocks 8 can also be adjusted to push glass bottles with different outer diameter. After adjustment, the spacer block 8 is locked to the slide rail 22 by the threaded set screw, which improves the applicability of the device.
[0054] It should be noted that the logical movement of each component in this case can be automatically programmed and controlled by an external control system. Other selected electrical control components such as related sensors and induction switches required for electrical control are not within the protection scope of this case and will not be elaborated further. Operators can select appropriate electrical control components according to their needs.
[0055] The glass bottle pushing device with segmented push rod provided by this invention is used as follows: Please refer to... Figure 6Initially, the push rod body is located on one side of the glass bottle, flush with the lower part of the rows of glass bottles on the conveyor belt. The sliding driver 17 pushes the longitudinal slide 16 to move towards the glass bottle, and each glass bottle enters between the corresponding two adjacent spacers 8. Under the action of the arc-shaped part 9, the glass bottle is positioned below the corresponding jet nozzle 6. After the sensor 11 detects that the glass bottle is in position, it transmits a signal to the external control system. The external control system controls the lifting drive 2 to move the lifting frame 3 downward. The bottle stopper 24 on the jet nozzle 6 enters the bottle mouth, while the jet end of the nozzle 7 is located at or slightly above the bottle mouth. The electronic control valve 10 opens, and a negative pressure is generated above the bottle mouth under the action of high-speed airflow. The gas inside the glass bottle is "sucked out," and the glass bottle... As the air pressure inside decreases, a pressure difference is created between the air pressure at the bottom of the glass bottle and the air pressure inside and above the glass bottle. The glass bottle is "lifted" upward by atmospheric pressure, and the force exerted by the glass bottle on the conveyor belt decreases. As the longitudinal slide 16 continues to move, the rollers 20 on the transverse slide 18 contact the guide slope 19 and roll along the inclined edge of the guide slope 19. The guide slope 19 creates a synchronous longitudinal and transverse pushing effect on the transverse slide 18. The glass bottle is pushed out from the conveyor belt. The lifting platform 21 drives the frame 1 to move upward. The bottom of the push rod body disengages from the glass bottle and is higher than the glass bottle. The sliding driver 17 drives the longitudinal slide 16 to reset. Under the action of the reset drive 23, the transverse slide 18 resets, ready to unload the next row of glass bottles at the conveyor belt.
[0056] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
