[0002] A bottle making machine is a piece of mechanical equipment used to manufacture glass bottles and jars. The forming molds of a bottle making machine require oiling after a certain period of operation. This involves applying a release agent to the molds to ensure the mold's service life and the quality of the resulting bottles and jars. During the production process, the bottle making machine must perform a series of actions, and oiling must be performed within a short time interval without colliding with the rotating machine mechanism. Currently, oiling is primarily performed manually. However, the quality of manual oiling varies from person to person, making it difficult to achieve standardized control of product quality. The labor intensity is high, and work efficiency is low. Furthermore, the equipment is exposed to high-temperature molten glass, which poses certain risks. Summary of the Invention

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please refer to Figure 1 and Figure 2 As shown, the automatic oiling device 20 for a bottle making machine according to an embodiment of the present invention includes a control component 210 , a guide rail 220 , a position sensor 240 , a moving base 250 , a robotic arm 260 and an oiling component 270 .

[0028] The control component 210 is electrically connected to the position sensor 240 , the moving base 250 , the robotic arm 260 and the oiling component 270 .

[0029] The movable base 250 is mounted on the guide rail 220 and is capable of moving along the guide rail 220. A robotic arm 260 is mounted on the movable base 250, and an oiling component 270 is mounted on the robotic arm 260. The robotic arm 260 is used to drive the oiling component 270 to the molding die 30 for oiling. A position sensor 240 is used to detect the position of the movable base 250 on the guide rail 220. Multiple position sensors 240 are provided, distributed along the guide rail 220. The control component 210 controls the docking position of the movable base 250 based on signals fed back from the position sensors 240.

[0030] The automatic oiling device for a bottle making machine includes a control component, a guide rail, a position sensor, a movable base, a robotic arm, and an oiling component. The movable base is disposed on the guide rail, the robotic arm is disposed on the movable base, and the oiling component is disposed on the robotic arm. The movement of the movable base can drive the robotic arm and the oiling component thereon to move. Multiple position sensors correspond one-to-one to the positions of multiple forming molds. The control component controls the docking position of the movable base based on signals fed back by the position sensors, causing the robotic arm to move to the forming mold. The robotic arm drives the oiling component to the forming mold for oiling within a time interval without colliding with the rotating bottle making machine mechanism, and then moves to the next forming mold for oiling after completion. Thus, the automatic oiling device for a bottle making machine and the bottle making machine can realize the automation of the oiling work without stopping the machine, ensuring the uniform oiling quality of each group of forming molds, which is not affected by human factors. At the same time, it reduces the labor intensity of personnel, improves work efficiency, and avoids the personal danger of manual oiling.

[0031] It is understandable that the control component 210 can be a commonly used controller, such as the control component 210 can be but not limited to an industrial computer, a programmable logic controller (PLC), etc.

[0032] Guide rails 220 are constructed from high-precision rails to enhance travel accuracy, thereby improving the precision with which the robotic arm 260 guides the oiling component 270 to the mold during oiling. Guide rails 220 include a drag chain 221, which houses a built-in cable 230. Cable 230 connects the moving device to the control component 210, exchanging signals and implementing control actions.

[0033] like Figure 2 As shown, in one example, the moving seat 250 includes a base 251 and a driving mechanism, and the base 251 is powered by the driving mechanism to achieve movement on the guide rail 220. In the specific example shown in the figure, the driving mechanism includes a servo motor 252 and a reducer 253 connected to the servo motor 252.

[0034] In one example, the robotic arm 260 is mounted upside down on the moving base 250. In one example, the robotic arm 260 is mounted on the moving base 250 via a connecting flange 254.

[0035] Robotic arm 260 is preferably a small robot arm. It utilizes its size to reach into the interior of the linear bottle making machine, avoiding contact with other components. Its arm span is sufficient to reach into the mold cavity, and its load capacity is sufficient to freely move the oiling component 270. Robotic arm 260 is preferably heat-resistant, dust-proof, and oil-proof to adapt to the operating environment of a linear bottle making machine.

[0036] Preferably, robotic arm 260 has at least three joints to enable flexible movement of oiling component 270 in three dimensions. In one specific example, robotic arm 260 has six joints. Before oiling, several joints work together to retract oiling component 270 into a desired position. During oiling, several joints work together to extend oiling component 270 into a desired position.

[0037] like Figure 2 As shown, in one example, the oiling component 270 includes a spray gun bracket 271 and a spray gun 272. The spray gun bracket 271 is set on the robot arm 260, and the spray gun 272 is set on the spray gun bracket 271. More specifically, the spray gun bracket 271 is connected to the last section of the robot arm 260 through a flange 261.

[0038] In one example, a spray gun 272 is provided with multiple spray holes of varying diameters to control the spray pressure. The oil mist sprayed from these holes has different spray distances. By designing the diameters of the various spray holes, the atomized spray can be aligned with the shape of the mold cavity, ensuring uniform contact across the cavity and ensuring even oiling of concave and convex areas.

[0039] It is understood that the oiling method is not limited to spraying. In other examples, the oiling component 270 can also be a brush, such as an oil brush, a rotating brush, etc. Alternatively, the oiling component 270 can include both a spray gun 272 and a brush to address specific needs such as molds with different bottle shapes and localized oiling locations.

[0040] like Figure 2 As shown, in one example, the automatic oiling apparatus 20 for a bottle making machine further includes a storage tank 280. Storage tank 280 is disposed on the movable base 250 and is in communication with the spray gun 272. In this example, the storage tank 280 stores release oil and moves with the movable base 250. During the oiling process, the storage tank 280 delivers the oil to the spray gun 272 via a pipeline.

[0041] Furthermore, the storage tank 280 has a storage cavity and an air inlet, an air outlet 282, and an oil outlet 283 connected to the storage cavity. The air inlet is used to input compressed gas into the storage cavity. The air outlet 282 is connected to the first pipe 291, and the oil outlet 283 is connected to the second pipe 292. The first pipe 291 and the second pipe 292 converge and connect to the third pipe 293, which is connected to the spray gun 272.

[0042] Preferably, the first, second, and third conduits 291, 292, and 293 are arranged along the robotic arm 260 to avoid being scattered and affecting the movement of the bottle-making components. The first, second, and third conduits 291, 292, and 293 are preferably made of high-temperature-resistant, flexible tubing to withstand high-temperature operating environments and flexibly deform with the movement of the various joints of the robotic arm 260.

[0043] A control valve 294 is located at the confluence of the first and second conduits 291 and 292. This valve is electrically connected to the control unit 210 and is controlled to open and close by the control unit 210. When the control valve 294 is opened, the compressed gas in the storage chamber forces the oil out, which then flows through the second conduit 292 and into the third conduit 293. The oil then flows along with the airflow through the third conduit 293 and into the spray gun 272. The control valve 294 is preferably a fast-acting valve.

[0044] It is understandable that a delivery pump may be provided on the third pipeline 293 for pumping oil to the spray gun 272 .

[0045] In one example, a stirring mechanism 284 is provided in the storage cavity. The stirring mechanism 284 is used to stir the oil in the storage cavity to make the oil uniform.

[0046] like Figure 2 As shown, in one example, the automatic oiling device 20 for a bottle making machine further includes an air pressure detector 310. The air pressure detector 310 is provided on the storage tank 280 and is used to detect the air pressure in the storage cavity.

[0047] Furthermore, an air pressure regulating valve 320 is provided on the air intake pipe connected to the air inlet of the storage tank 280. The air pressure detector 310 and the air pressure regulating valve 320 are electrically connected to the control component 210 respectively. The control component 210 controls the opening of the air pressure regulating valve 320 according to the signal feedback from the air pressure detector 310 to control the air pressure in the storage cavity to be within a set range.

[0048] In one example, an air source processing triplex 330 is provided on the air inlet pipe connected to the air inlet of the storage tank 280. More specifically, the air source triplex consists of a water separator, a pressure reducing valve, and an oil mist collector, which are used to filter moisture, regulate pressure, and add lubricating oil mist, respectively.

[0049] like Figure 2 As shown, the air pressure regulating valve 320 and the air source processing triplet 330 are both disposed in a mobile electric control box 340, which is disposed on the mobile base 250 and moves with the mobile base 250. It is understood that the mobile electric control box 340 is also provided with electrical components.

[0050] like Figure 2As shown, in one example, the automatic oiling device 20 for a bottle making machine further includes a distance sensor 350, which is disposed on the movable base 250. The distance sensor 350 is used to detect the distance between the distance sensor 350 and the forming mold 30, thereby verifying the parking position of the movable base to ensure accurate positioning.

[0051] More specifically, a bracket 360 is provided on the moving base 250 , and the distance measuring sensor 350 is provided on the bracket 360 .

[0052] Please refer to Figure 3 As shown, in one example, the automatic oiling device 20 for a bottle making machine further includes a safety device 400, which is electrically connected to a control unit. The safety device 400 is mounted on a movable base 250. When an obstacle enters a protective zone 410 surrounding the safety device 400, the control unit controls the robot arm 260 to reset. Furthermore, the automatic oiling device 20 for the bottle making machine can be shut down to prevent the automatic oiling device 20 from colliding with an obstacle and potentially causing a production accident. It should be noted that the protective zone 410 in the accompanying drawings is merely a schematic representation and does not represent the actual size of the protective zone 410.

[0053] Furthermore, the protection zone 410 of the safety device 400 is the area scanned by the safety device 400 at a preset radius, with the safety device 400 itself as the center. This means that the area within the preset radius around the safety device 400 is the protection zone 410. For example, if the preset radius is 2 meters and the scanning angle of the safety device 400 is 200 degrees, that is, the angle between the starting radius and the ending radius of the safety device 400's scanning is 200 degrees, then the protection zone 410 faces the ground and focuses on monitoring obstacles on the ground. It is understood that the preset radius and preset angle of the protection zone 410 can be adjusted according to actual conditions.

[0054] Optionally, the security device 400 is any one of a three-dimensional space intrusion detector, a laser scanner, an image monitor, and a radar monitor.

[0055] like Figure 2 As shown, in one example, the automatic oiling device 20 for bottle making machine further includes a liquid level detector 370, which is disposed on the storage tank 280 and is used to detect the liquid level in the storage tank 280. In one example, the liquid level detector 370 is a differential pressure detector.

[0056] Furthermore, the automatic oiling device 20 for the bottle making machine also includes an alarm (not shown in the figure). The alarm and the liquid level detector 370 are electrically connected to the control component 210. When the liquid level detector 370 detects that the liquid level in the storage tank 280 is lower than the set value, the control component 210 controls the alarm to sound an alarm.

[0057] like Figure 2 As shown, in one example, the automatic oiling device 20 for the bottle making machine further includes a temperature detector 380 . The temperature detector 380 is disposed on the storage tank 280 and is used to detect the temperature of the oil in the storage tank 280 .

[0058] Furthermore, the temperature detector 380 is electrically connected to the control component 210. When the temperature detector 380 detects that the temperature in the storage tank 280 exceeds a set value, the control component 210 controls the alarm to sound an alarm.

[0059] like Figure 1 As shown, in one example, the automatic oiling device 20 for the bottle making machine is further provided with a display screen 390 for the operator to operate and view the operation status of the device.

[0060] Furthermore, the present invention provides a bottle making machine comprising a machine base, a forming mold, and the automatic lubricating device 20 for the bottle making machine described in any of the above examples. The machine base comprises multiple forming molds, each of which is mounted on the machine base. A guide rail 220 is mounted on the machine base and positioned above the forming molds. Multiple position sensors 240 correspond to the positions of the multiple forming molds.

[0061] like Figure 4 and Figure 5 As shown, in one example, the oiling component 270 further includes a limiting mechanism 273 , a telescopic elastic member 274 , a pressing mechanism 275 and a closing mechanism 276 .

[0062] The release agent is sprayed outwards via a spray gun 272. The spray gun 272 is an aerosol spray gun 272, which can spray the release agent in the form of aerosol.

[0063] The limiting mechanism 273, the retractable elastic member 274, the pressing mechanism 275, and the closing mechanism 276 are sequentially mounted on the spray gun 272 along the discharge direction of the spray gun 272. The ends of the retractable elastic member 274 elastically abut against the limiting mechanism 273 and the pressing mechanism 275, respectively. The closing mechanism 276 has a first side 2761 and a second side 2762 opposite the first side 2761. Furthermore, the closing mechanism 276 is provided with an exhaust hole 2763 extending from the first side 2761 to the second side 2762. The pressing mechanism 275 is movably connected to the spray gun 272 and is movable along the spray gun 272. Under the elastic force of the retractable elastic member 274, the pressing mechanism 275 is pressed against the second side 2762 of the closing mechanism 276, and the pressing mechanism 275 covers the exhaust hole 2763.

[0064] Currently, the method for spraying release agent involves inserting the nozzle of an oil sprayer into the mold cavity when the preform mold is closed, spraying an aerosolized release agent. However, because the oil sprayer cannot precisely control the amount of release agent sprayed each time, it can sometimes spray excessive amounts, significantly impacting the quality of the bottles produced, leading to excessive bottle defects and a decrease in product yield. Furthermore, in high-temperature environments, some of the sprayed aerosolized release agent evaporates outside the mold cavity, resulting in significant waste and uneven distribution of release agent within the mold cavity, resulting in poor release. The automatic oiling device 20 for bottle-making machines, as described above, can address this problem.

[0065] Specifically, when spraying release agent into the preform mold of a bottle making machine, the preform mold is first closed, and a spray gun 272 is inserted into the mold cavity through the preform mold opening. The sealing mechanism 276 seals the mold opening to seal the mold cavity, and then aerosol release agent is sprayed into the mold cavity. Since the sealing mechanism 276 seals the mold opening, the mold cavity forms a closed space, which prevents excessive waste of release agent due to high-temperature volatilization, thereby saving release agent usage and reducing material costs. At the same time, the atomized release agent is fully in contact with the mold cavity within the closed preform mold cavity, achieving uniform adsorption.

[0066] The sealing mechanism 276 is provided with an exhaust hole 2763. When the sealing mechanism 276 seals the die opening, the exhaust hole 2763 communicates with the die cavity. The capping mechanism 275 is pressed against the sealing mechanism 276 by the elastic force of the retractable elastic member 274 and covers the exhaust hole 2763 on the sealing mechanism 276. When the dosage of the release agent sprayed by the spray gun 272 is appropriate, the pressure in the mold cavity of the primary mold is insufficient to lift the capping mechanism 275. When the dosage of the release agent sprayed by the spray gun 272 is too much, the air pressure inside the mold cavity is high, exceeding the pressure exerted by the capping mechanism 275 on the sealing mechanism 276. At this time, the capping mechanism 275 is lifted by the aerosol, and the excess release agent overflows from the die cavity through the exhaust hole 2763. This avoids the problem of excessive dosage of release agent, which would cause excessive defects in the manufactured bottles and reduce the yield rate.

[0067] It can be understood that the closing mechanism 276 is provided with a first mounting hole, and the spray gun 272 is passed through the first mounting hole.

[0068] Optionally, the closing mechanism 276 and the spray gun 272 can be fixedly connected, that is, the position of the closing mechanism 276 on the spray gun 272 is fixed. The closing mechanism 276 and the spray gun 272 can also be movably connected, that is, the position of the closing mechanism 276 on the spray gun 272 is adjustable.

[0069] In one example, the closing mechanism 276 is a flat plate structure having two plate surfaces, namely a first side 2761 and a second side 2762 , wherein the second side 2762 faces the capping mechanism 275 .

[0070] In one example, the closing mechanism 276 is a circular plate-shaped structure. Further, the first mounting hole is provided at the center of the closing mechanism 276 .

[0071] It is understood that in other examples, the closing mechanism 276 is not limited to being a flat plate structure, as long as the closing mechanism 276 can cover the die opening of the prototype mold.

[0072] Preferably, the sealing mechanism 276 is made of a high temperature resistant material and can withstand the high temperature environment of the primary mold.

[0073] Optionally, the number of the exhaust holes 2763 is not limited to only one, and there may be multiple exhaust holes.

[0074] In one example, there are multiple exhaust holes 2763 , and the multiple exhaust holes 2763 are centrally symmetrically distributed around the axis of the spray gun 272 .

[0075] In one example, all of the vent holes 2763 have the same shape and size.

[0076] In a specific example, the sealing mechanism 276 is provided with four exhaust holes 2763 of the same shape and size, and the four exhaust holes 2763 are centrally symmetrically distributed with the axis of the spray gun 272 as the center.

[0077] It is understood that the capping mechanism 275 is provided with a second mounting hole, and the spray gun 272 is passed through the second mounting hole. The capping mechanism 275 is movably connected to the spray gun 272 and can move along the spray gun 272.

[0078] In one example, the capping mechanism 275 is a flat plate-shaped structure.

[0079] In one example, the cover pressing mechanism 275 is a circular plate-shaped structure. Further, the second mounting hole is provided at the center of the cover pressing mechanism 275 .

[0080] In one example, the capping mechanism 275 is coaxially arranged with the closing mechanism 276 .

[0081] It can be understood that in other examples, the cover mechanism 275 is not limited to a flat plate structure, as long as it can cover all the exhaust holes 2763 on the closing mechanism 276.

[0082] In one example, the vent hole 2763 on the closing mechanism 276 is located near the edge of the capping mechanism 275. In this way, excess release agent is more likely to overflow to the outside through the vent hole 2763.

[0083] Preferably, the capping mechanism 275 is made of a high-temperature resistant soft material, such as rubber, which can withstand the high temperature environment of the primary mold and make it easier for excess release agent to overflow to the outside through the exhaust hole 2763.

[0084] As will be understood, the telescopic elastic member 274 is provided with a third mounting hole, through which the spray gun 272 is inserted. The ends of the telescopic elastic member 274 elastically abut against the limiting mechanism 273 and the pressing mechanism 275, respectively. As the distance between the limiting mechanism 273 and the pressing mechanism 275 moves closer or further, the telescopic elastic member 274 contracts or extends. As will be understood, when the telescopic elastic member 274 contracts, the elastic force applied to the pressing mechanism 275 increases, and when the telescopic elastic member 274 extends, the elastic force applied to the pressing mechanism 275 decreases.

[0085] In one example, the telescopic elastic member 274 is a spring, and the elastic coefficient of the spring can be selected according to actual conditions.

[0086] In one example, the position of the limiting mechanism 273 on the spray gun 272 is adjustable. More specifically, the limiting mechanism 273 is movably connected to the spray gun 272 and can move along the spray gun 272 to adjust the distance between the limiting mechanism 273 and the capping mechanism 275.

[0087] In the above-mentioned example, the oiling component 270 and the position of the limiting mechanism 273 on the spray gun 272 are set to be adjustable. Before the spraying work, the oiling component 270 can be debugged. After determining the dosage of the release agent sprayed each time based on the spraying effect or experience, by adjusting the position of the limiting mechanism 273 on the spray gun 272, when the release agent is sprayed, the force of the release agent on the capping mechanism 275 and the force of the telescopic elastic member 274 on the capping mechanism 275 are roughly balanced. If the dosage of the release agent is too large when spraying, the air pressure in the mold cavity will lift the capping mechanism 275, and the excess release agent will overflow to the outside of the mold cavity through the exhaust hole 2763, thereby avoiding overspraying and achieving the purpose of controlling the spraying amount.

[0088] If after the position of the limiting mechanism 273 is adjusted, from the perspective of the spraying effect, it is considered that the amount of release agent sprayed each time is insufficient or excessive, the amount sprayed each time can be appropriately increased or decreased, and then the position of the limiting mechanism 273 can be adjusted again until a satisfactory spraying effect is achieved. The debugging of the oiling component 270 is then completed.

[0089] In one example, the limiting mechanism 273 has a threaded hole, and the surface of the spray gun 272 has a thread 2721. The limiting mechanism 273 is threadedly connected to the spray gun 272 through the threaded hole. The threaded connection between the limiting mechanism 273 and the spray gun 272 allows for more precise adjustment of the position of the limiting mechanism 273 on the spray gun 272.

[0090] In one example, the limiting mechanism 273 is a nut. Furthermore, in one example, the limiting mechanism 273 is a self-locking nut. A self-locking nut can self-lock by friction, preventing loosening and displacement due to vibration during use, thereby ensuring that the retractable elastic member 274 is pressed tightly against the cover mechanism 275.

[0091] In one example, the oiling component 270 further includes a gasket 277. The gasket 277 is sleeved on the spray gun 272 and is located between the limiting mechanism 273 and the telescopic elastic member 274.

[0092] In one example, the limiting mechanism 273, the telescopic elastic member 274, the pressing cover mechanism 275 and the spray gun 272 are detachably connected, so that the limiting mechanism 273, the telescopic elastic member 274 and the pressing cover mechanism 275 can be easily removed from the spray gun 272 for replacement or cleaning.
