Description

Technical Field

[0001] The utility model relates to the field of filling equipment, in particular to an automatic filling machine. Background Art

[0002] Existing automatic filling equipment generally adopts a fixed filling method of vertical drop. Although this design is simple and direct, it has certain limitations in practical applications. For liquids with lower viscosity, such as beverages and skin care water, due to their strong fluidity, dripping is prone to occur during the filling process. This not only affects the accuracy of filling, but may also cause contamination of packaging materials. In order to solve this problem, it is usually necessary to use other devices or methods, such as automatic cleaning devices or regular manual cleaning, to keep the production line clean and efficient. For liquids with higher viscosity, such as honey, chocolate, resin, etc., residue is prone to occur at the filling port. This not only reduces the filling efficiency, but may also cause material waste. In order to improve the filling accuracy of high-viscosity liquids, it is also necessary to add additional auxiliary quantitative mechanisms, such as cutting devices, but there may be safety hazards during use.

[0003] Existing automatic filling equipment is often designed for specific liquid types, requiring frequent replacement or adjustment of equipment during R&D and production, increasing costs. There is also a lack of universal equipment that can support the automatic filling of liquids with different viscosities. Utility Model Content

[0004] The purpose of the present invention is to address the deficiencies of the prior art. The present invention aims to provide an automatic filling machine, in which the filling mechanism can automatically move to a specified position. After each quantitative filling is completed, the filling mechanism can be controlled to lift up and cut off high-viscosity liquid, or to rotate and drop low-viscosity liquid, thereby effectively avoiding the problems of residue and dripping.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an automatic filling machine, including a motion control mechanism, a filling mechanism, and a posture adjustment mechanism, wherein the motion control mechanism is used to control the action element to perform the action according to the path planning; the filling mechanism is loaded with the liquid to be filled, and after aligning with the filling container, the target liquid is squeezed out; the posture adjustment mechanism is used to realize multiple motion posture adjustments of the filling mechanism, and the motion control mechanism includes at least three groups of mutually perpendicular linear modules, which constitute three-dimensional space coordinates, and each linear module includes a guide rail, a slider and a driving element; the filling mechanism is provided with a limiter and a fixing member, the limiter limits the filling mechanism from shaking displacement other than the moving direction of the filling mechanism, and the fixing member limits the displacement in the moving direction of the filling mechanism during the filling process; the posture adjustment mechanism includes a first posture adjustment mechanism for adjusting the angle of the filling mechanism relative to the horizontal plane, and a second posture mechanism for adjusting the rotation of the filling mechanism along the moving direction axis.

[0006] The stopper has an adjustable groove structure for matching the filling mechanism to lock in. It fixes the tail end of the filling mechanism to prevent the filling mechanism from shifting in the direction of the moving axis during the filling process.

[0007] Furthermore, the first posture adjustment mechanism includes a swinging guide rod mechanism and a motor. The swinging guide rod mechanism enables the guide rod to swing back and forth within a range of 0 to 90 degrees, with the motor serving as the power source. The second posture mechanism includes a rotating shaft, a motor, a brake assembly, and a connecting assembly. The rotating shaft is supported by bearings and connected to the filling mechanism. The brake assembly is used to maintain the current posture when the rotating shaft needs to be stopped or in the event of a power outage.

[0008] The significance of the present invention is also to provide an automatic filling machine, in which the filling mechanism can automatically move to a designated position. After each quantitative filling is completed, it can be controlled to lift up and cut off high-viscosity liquids, or controlled to rotate and throw off low-viscosity liquids, thereby effectively avoiding the problems of residue and dripping, and then automatically move to the next location to continue the filling task until all work is completed. The present invention is suitable for filling scenarios of liquids with different viscosities, and has no restrictions on the type and size of the filling container. Users can adjust the unit filling volume and filling motion trajectory according to actual needs. The significance of the present invention is also to enhance the versatility of the automatic filling device, adjust the filling strategy according to the viscosity of the solution, so that the same equipment can flexibly adapt to changing production environments, meet the filling needs of different types of liquids, and reduce equipment investment costs for small and medium-sized enterprises.

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0013] The utility model mainly consists of five parts: a motion control mechanism, a filling mechanism, a posture adjustment mechanism, a mounting mechanism and a control system.

[0014] Motion control mechanism: This mechanism is used to move the actuator to the specified coordinates and control the actuator to execute the motion according to the planned path. It includes three sets of mutually perpendicular automated transmission devices, forming a three-dimensional spatial coordinate system. The automated transmission devices can be linear modules, each of which includes a guide rail, a slider, and a drive element. The drive element can be a pneumatic cylinder, an electric cylinder, or a motor, preferably a servo motor.

[0015] Filling mechanism: loads the liquid to be filled, and after aligning it with the filling container, squeezes out the target liquid. It includes an injection assembly, a fixing assembly, a propulsion assembly and a base. The injection assembly includes a syringe and a piston rod, which are used to load the liquid. The fixing assembly includes a limiter and a fixing assembly, which are used to prevent the injection assembly from accidentally moving to ensure injection accuracy. The limiter has an adjustable groove structure, which is used to match the injection assembly to limit the jitter displacement of the injection assembly except in the long axis direction, but does not limit the rotation of the injection assembly along the central long axis; the fixing assembly is used to fix the tail end of the syringe to prevent the syringe from displacing in the long axis direction during the filling process. The propulsion assembly includes a screw, a linear guide, a pressure plate and a motor, which are used to apply extrusion force to the piston rod to extrude the target liquid in a quantitative manner. The base is used to fix and support the various components of the filling mechanism to ensure structural stability.

[0016] The posture adjustment mechanism is used to adjust the filling mechanism's various postures, such as swing and rotation. It comprises a first posture adjustment mechanism and a second posture adjustment mechanism. The first posture adjustment mechanism adjusts the filling mechanism's angle relative to the horizontal plane and includes a swinging guide rod mechanism and a motor. The swinging guide rod mechanism enables the guide rod to swing back and forth within a range of 0 to 90 degrees, with the motor serving as the power source. The first posture adjustment mechanism is located between the filling mechanism and the motion control mechanism. The second posture adjustment mechanism adjusts the filling mechanism's rotation along its central longitudinal axis and includes a rotating shaft, a motor, a brake assembly, and a connecting assembly. The rotating shaft is supported by bearings and connected to the filling mechanism. The brake assembly maintains the current posture when the rotating shaft needs to be stopped or in the event of a power outage. The posture adjustment mechanism can preset the appropriate injection angle before filling to accommodate liquids of varying viscosities and container shapes. It can also rotate or lift the filling mechanism during operation to discard low-viscosity liquids or cut off high-viscosity liquids, achieving more effective quantitative control.

[0017] Control system: An editable logic controller is used to send instructions to the motors to achieve six-axis coordinated operation, allowing users to set parameters according to different products and filling requirements, including hardware and software.

[0018] In order to make the technical problems to be solved by the present invention, the technical solutions proposed, and their beneficial effects more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. The scope of protection of the present invention is not limited by the specific embodiments.

[0019] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the utility model. Figure 1 The three groups of mutually perpendicular linear modules constitute the X-axis, Y-axis and Z-axis in three-dimensional space, which are used to control the movement of the injection site within the range of the device. Among them, the Y-axis 101 is fixed to the large base plate 401, and is composed of two mutually parallel and aligned linear modules, and also serves as the bottom support of other axes. The slider 1013 thereon is connected to the X-axis 102 through a connecting rod. One end of the connecting rod is provided with a thread and is fixed to the mounting surface of the linear module by bolts. The connecting rod is made of high-strength aluminum alloy material to ensure that the structure is light and stable. The first motor 1011 controls the connected X-axis 102 to move in the direction of the Y-axis 101. The Z-axis 103 is connected to the X-axis 102, and the Z-axis 103 can move in the direction of the X-axis 102. The Z-axis 103 is connected to the small base plate 201, and finally realizes the free movement of the injection mechanism on the small base plate 201 in three-dimensional space.

[0020] The small base plate 201 features an arc-shaped slot with an angle of 0 to 90 degrees, serving as an angled guide 2011. A second motor 2012 controls the injection mechanism's oscillation in the XZ plane. The syringe 202 rests against the stopper slot 2031. A fixing clip 2032, equipped with a positioning hole, engages with the clip via bolts to secure the end of the syringe barrel. A third motor 301 controls the push plate 2033's quantitative movement along the guide rail 1012, driving the syringe piston rod to expel liquid and also controlling the rotation of the entire injection mechanism along its central longitudinal axis. The large base plate 401 is equipped with multiple mounting holes. A positioning plate is mounted on the large base plate 401 and engages with the mounting holes via bolts. The positioning plate has positioning slots that determine the position of the components to be mounted thereon. A connecting plate is connected to the positioning plate via welding or bolts and features reinforcing ribs to enhance the stability of the entire mechanism. The container area 402 secures molds or containers arranged in a matrix, enabling program-controlled continuous filling.

[0021] The operation process is to add the liquid to be filled into the syringe 202, fix the syringe 202 on the device through the syringe holder 203, fix the mold to be filled to the container area 402 on the large base plate 401, control the syringe needle to move to the filling starting position through the XYZ axis, and then run according to the pre-set program. The operation steps include pushing the syringe 202 to squeeze out the liquid, and at the same time coordinating the translation in the direction of the X-axis 102 to match the rectangular structure of the mold so that the viscous liquid can cover the entire cavity. After one grid is filled, the syringe 202 swings upward to cut off the high-viscosity liquid, and then translates to the next filling position, and repeats the above operation. In order to improve efficiency, the motion program of the syringe 202 is set to "S-shaped" movement.

[0022] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and exemplary embodiments. They can be applied to a variety of fields suitable for the present invention. Further modifications will be readily apparent to those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrations shown and described herein without departing from the general concept defined by the claims and their equivalents.
