Abstract
Description
Technical Field
[0001] This application relates to a capping machine system. More specifically, this application relates to a capping machine system with a non-rotational torque sensor. Background Technology
[0002] A capping machine is a machine that locks a bottle cap onto a bottle by rotating the cap so that the inner thread of the cap engages with the outer thread of the bottle.
[0003] However, bottle caps may not lock properly due to misalignment or angle during installation, and existing capping machines often struggle to confirm whether the cap is securely locked onto the bottle after rotation. Because existing capping machines rely on pulleys or gears to transmit torque, requiring multiple transfers, a dynamic torque sensor is installed at the end of the machine. This increases the manufacturing cost of the capping machine. Therefore, solving these problems has become an important issue. Utility Model Content

[0042] The following describes a capping machine system and capping assembly according to embodiments of this application. However, it will be readily apparent that embodiments of this application provide many suitable inventive concepts that can be implemented in a wide range of specific contexts.

[0044] The following illustrations are specific examples of the various components and their arrangements to simplify the description of the invention. These specific examples are not intended to limit this application. For example, if the following illustrations describe a first feature formed on or above a second feature, it indicates that it includes embodiments where the first and second features are in direct contact, and also embodiments where additional features may be formed between the first and second features, so that the first and second features may not be in direct contact.

[0045] Figure 1 This is a schematic diagram illustrating a capping machine system C according to an embodiment of this application. The aforementioned capping machine system C can be used to install a bottle cap (not shown) onto the bottle opening B1 of a bottle B, and can confirm whether sufficient torque is provided to the bottle cap to lock the bottle cap onto the bottle B.
[0046] like Figure 1 and Figure 2 As shown, the capping machine system C mainly includes a motor 100, a reducer 200, a non-rotating torque sensor 300, a capping assembly 400, a base 600, and at least one drive component 800.
[0047] The motor 100 and the reducer 200 can constitute the shaft 120 of the capping machine system C. Specifically, the motor 100 can be connected to the reducer 200 via a coupling, and the reducer 200 is then connected to the coupling of the capping assembly 400 via a rotating shaft, thereby constituting the shaft 120 of the capping machine system C in this embodiment. The aforementioned shaft 120 can extend along the axis 121.
[0048] The reducer 200 is connected to and fixed relative to the motor 100. The reducer 200 can be used to reduce the speed of the motor 100 and increase torque to provide better stability during cap tightening. For example, the reducer 200 may include a gear reducer, a worm wheel reducer, a planetary gears reducer, a cycloid reducer, and / or combinations of the foregoing, but is not limited thereto.
[0049] The non-rotational torque sensor 300 can be connected to the reducer 200, and the reducer 200 can be positioned between the motor 100 and the non-rotational torque sensor 300. Specifically, the non-rotational torque sensor 300 is configured to detect the magnitude of the torque provided by the capping machine system C during the cap tightening process.
[0050] The cap assembly 400 includes a fixed base 410, a rotary slip ring 420, and a gripper 500. A non-rotational torque sensor 300 and the rotary slip ring 420 are fixed to the fixed base 410, with the fixed base 410 positioned between the non-rotational torque sensor 300 and the rotary slip ring 420. A shaft 120 passes through the non-rotational torque sensor 300 and the fixed base 410 and engages with the rotary slip ring 420. It should be noted that a distance is maintained between the shaft 120 and both the non-rotational torque sensor 300 and the fixed base 410; therefore, the non-rotational torque sensor 300 and the fixed base 410 will not rotate with the rotation of the shaft 120.
[0051] The gripper 500 can be connected to the rotary slip ring 420, and the rotary slip ring 420 can be connected to the gas supply device S. Gas is supplied to the rotary slip ring 420 through the gas supply device S, which will drive the gripper 500 to move and grasp the bottle cap.
[0052] In this embodiment, the gripper 500 may include a rotating portion 510 and at least one gripping portion 520. The rotating portion 510 is connected to the shaft 120 via a rotating slip ring 420, so that when the shaft 120 rotates, the rotating portion 510 of the gripper 500 can be driven to rotate. The gripping portion 520 is disposed on the rotating portion 510, and the gripping portion 520 can be driven by the rotating slip ring 420 to move relative to the rotating portion 510 in a direction closer to or away from the axis 121.
[0053] like Figure 1 As shown, in this embodiment, the fixing base 410 of the cap assembly 400 can be movably mounted on the base 600. For example, the base 600 may be provided with a guide rail 610 extending along a direction parallel to the axis 121, and a slider 620 movable along the guide rail 610 may be provided on the guide rail 610, and the fixing base 410 may be fixed to the slider 620. In this way, the cap assembly 400 and the motor 100, reducer 200, non-rotational torque sensor 300 and gripper 500 connected to the cap assembly 400 can be driven to move along the axis 121 when the slider 620 moves.
[0054] The drive assembly 800 includes a drive part 810 and a fixing part 820. The drive part 810 may include, for example, a cylinder, and the drive part 810 can drive the fixing part 820 to move toward the bottle or can, so that the bottle or can B can be fixed by the drive assembly 800.
[0055] The following describes how to use the capping machine system C. When a user wants to use the capping machine system C to install a bottle cap onto the bottle mouth B1 of bottle B, the rotating slip ring 420 can drive the gripping part 520 of the gripper 500 to move toward the axis 121 to grip the bottle cap, and the drive assembly 800 can grip bottle B so that the bottle mouth B1 of bottle B is aligned with the gripper 500 (that is, so that the axis 121 of the axis 120 overlaps with the bottle mouth B1).
[0056] Next, the slider 620 can move along the guide rail 610 toward bottle B, and the bottle cap held by the gripper 500 can contact bottle B. Finally, the motor 100 can drive the gripper 500 to rotate, so that the bottle cap is locked.
[0057] It should be noted that because the motor 100, reducer 200, and non-rotational torque sensor 300 are fixed relative to each other and to the mounting base 410, a reaction force will be transmitted to the motor 100 when the cap is tightened onto the bottle B. The non-rotational torque sensor 300 can measure this reaction force to determine whether the torque output to the cap assembly 400 reaches the desired default value.
[0058] If the measured torque reaches the default value, it indicates that the bottle cap has been securely locked onto bottle B. The rotating slip ring 420 can drive the gripper 500 to move away from axis 121 to release the bottle cap. If the measured torque does not reach the default value, it indicates that the bottle cap is not securely locked onto bottle B (e.g., due to misalignment of the installation angle). The axis 120 can be rotated in the opposite direction, and the locking process can be repeated.
[0059] Furthermore, since the motor 100, reducer 200, non-rotating torque sensor 300 and capping assembly 400 in the capping machine system C of this application embodiment are arranged along axis 121, the torque provided by the motor 100 can be directly transmitted to the capping assembly 400 without the need for transmission through other components (such as pulleys or gears). Therefore, the torque transmission efficiency of the capping machine system C can be improved and the manufacturing cost of the capping machine system C can be reduced.
[0060] For example, the aforementioned usage methods can be found in [reference]. Figure 3 In step S1, the motor 100 can input torque to the reducer 200. In step S2, the reducer 200 can then output torque to the cap assembly 400.
[0061] In step S3, the cap assembly 400 can lock the cap. Then, in step S4, the non-rotational torque sensor 300 can confirm whether the torque output to the cap assembly 400 has reached a default value.
[0062] If the torque measured by the non-rotational torque sensor 300 does not reach the default value, step S5 can be performed. In step S5, the cap assembly 400 can be rotated in the opposite direction to loosen the cap from the bottle B, and after step S5, step S3 can be performed again.
[0063] If the torque measured by the non-rotational torque sensor 300 has reached the default value, then step S6 can be performed. In step S6, the gripper 500 can release the bottle cap, and the bottle cap can remain locked on the bottle B.
[0064] Please see Figure 4 In another embodiment of this application, the capping machine system C may include a motor 100, a non-rotational torque sensor 300, a capping assembly 400, a base 600, and at least one drive assembly 800, wherein the structure and configuration of the non-rotational torque sensor 300, the capping assembly 400, the base 600, and the drive assembly 800 are similar to those of the motor 100, the non-rotational torque sensor 300, the capping assembly 400, the base 600, and the drive assembly 800. Figure 1 and Figure 2 The embodiments are the same, so they will not be described again here.
[0065] In this embodiment, the shaft 120 can be formed solely by the rotating shaft of the motor 100, and the motor 100 can be directly fixed to the non-rotational torque sensor 300. In other words, the non-rotational torque sensor 300 can directly contact the motor 100, thus the non-rotational torque sensor 300 can measure the torque provided by the motor 100 more quickly and accurately.
[0066] In summary, this application provides a capping machine system, including a motor, a shaft, a capping assembly, and a non-rotational torque sensor. The motor constitutes at least a portion of the shaft. The capping assembly is connected to the shaft and includes a fixed base. The non-rotational torque sensor is fixed to the fixed base and does not rotate with the shaft. The non-rotational torque sensor measures whether the torque output to the capping assembly reaches a default value.
[0067] This application also provides a cap assembly, which is connected to a shaft, and the shaft provides torque to the cap assembly. The cap assembly includes a fixed base and a rotary slip ring. The rotary slip ring is connected to the fixed base and engaged with the shaft.
