Description

Technical Field

[0001] This utility model relates to the field of bottle handling equipment technology, and in particular to a bottle splitting mechanism. Specifically, it is a bottle splitting mechanism for diverting bottles arranged in a single channel to a dual channel, and is applicable to filling production lines in industries such as beverages and pharmaceuticals. Background Technology

[0002] On bottle packaging production lines, bottles are typically sorted by bottle unscramblers and then output in an orderly manner through a single channel. However, to improve production efficiency, subsequent processes such as filling machines often require dual or multi-channel input to achieve parallel processing. This necessitates the installation of a flow diversion mechanism between single-channel and dual-channel systems.

[0003] In existing technologies, common diversion methods include mechanical levers, slides, or turntable mechanisms. However, these mechanisms have the following problems: First, mechanical levers are prone to causing bottles to jam or tip over due to irregular bottle shapes or speed mismatches. Second, slide mechanisms rely on gravity for diversion, but bottles are prone to collisions or accumulation in the slide, affecting transmission stability. Furthermore, although turntable mechanisms can achieve smooth transmission, traditional turntable designs are simple and lack precise control, making them prone to positional deviations at high speeds, causing bottles to fail to accurately enter the dual channels.

[0004] For example, some existing diversion devices rely on simple mechanical linkages or pneumatic controls, which suffer from low control accuracy and poor stability. They are prone to jamming when the bottle flow rate is high, and cannot meet the needs of modern high-speed production lines. These existing technologies have not effectively solved the problems of bottle jamming and low efficiency in high-speed production, and their mechanisms are complex and maintenance costs are high.

[0005] Therefore, there is an urgent need in this field for a bottle splitting mechanism that is simple in structure, precise in control, and highly reliable, in order to improve the overall efficiency and stability of the production line. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bottle splitting mechanism, which achieves smooth and efficient bottle splitting by optimizing the mechanism design and control logic, reducing bottle jamming, and improving the automation level and reliability of the production line.

[0007] The above-mentioned utility model objective is achieved through the following technical solution:

[0008] This invention provides a bottle splitting mechanism, comprising a single-channel bottle feeding conveyor belt, a small turntable, a main turntable, a drive servo, a dual-group gripping mechanism, a transition port blocking and lifting mechanism, and a gripping and translating mechanism. The single-channel bottle feeding conveyor belt is used to orderly transport bottles to the small turntable. The small turntable is intermittently rotated under the control of the drive servo, allowing the bottles to enter the working position. The dual-group gripping mechanism is used to grip the bottles. The transition port blocking and lifting mechanism is vertically and vertically arranged in the transition channel between the small turntable and the main turntable. The gripping and translating mechanism is used to translate the gripped bottles to the corresponding working position on the main turntable.

[0009] According to one embodiment of the present invention, the single-channel bottle feeding conveyor belt includes a belt drive system, a guide rail, and a speed sensor. The belt drive system is driven by a motor, the guide rail is used to limit the position of the bottles, and the speed sensor is used to monitor the conveying speed and feed it back to the control system.

[0011] According to one embodiment of the present invention, the main turntable includes two parallel turntable channels, each channel being equipped with an independent drive motor and a position detector. The rotation of the main turntable is synchronized with the gripping and translation mechanism to ensure a smooth transition of the bottle.

[0012] According to one embodiment of the present invention, the drive servo is a servo motor system, including an encoder, a reducer and a controller. The encoder is used to provide position information, and the controller controls the intermittent movement of the small turntable according to a preset program.

[0013] According to one embodiment of the present invention, the dual-grip mechanism includes two sets of robotic arms, each set of robotic arms being pneumatically or electrically driven and having gripping claws and pressure sensors. The gripping claws can adjust the gripping force to adapt to different bottle shapes.

[0014] According to one embodiment of the present invention, the transition port blocking lifting mechanism is a lifting plate driven by a cylinder or an electric push rod. When the lifting plate is in the blocking position, it closes the transition channel, and when it is in the descending position, it allows the bottle to pass through. The transition port blocking lifting mechanism is equipped with a position sensor for detecting the lifting status.

[0015] According to one embodiment of the present invention, the gripping and translation mechanism includes a linear guide rail, a slider and a drive motor. The slider is equipped with a double gripping mechanism. The drive motor drives the slider to move horizontally through a lead screw or belt. The translation distance is adjustable to adapt to different workstation spacings.

[0016] According to one embodiment of the present invention, a control system is also included. The control system is a PLC or a microprocessor, which is electrically connected to the drive servo, the gripping mechanism, the transition port blocking lifting mechanism, and the gripping translation mechanism to realize automated control. The control system has a preset working cycle, including the timing logic of the small turntable rotation, gripping, lifting, translation, and release.

[0017] According to one embodiment of the present invention, the control system further includes a human-machine interface for parameter setting and fault diagnosis; the system supports communication interfaces with upstream bottle unscramblers and downstream filling machines to achieve production line integration.

[0018] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects:

[0021] 3. Strong adaptability: The key components of the mechanism (such as the clamping force and translation distance of the gripping mechanism) are adjustable, which can adapt to bottles of different shapes and sizes, thus enhancing the versatility of the mechanism.

[0022] 4. Compact structure and integration: The overall layout is reasonable and the structure is compact, making it easy to integrate with existing bottle unscramblers, filling machines and other equipment, thus reducing the cost of production line transformation.

[0023] 5. Easy maintenance: The modular design makes it easier to maintain and replace each component, reducing the life cycle cost of the equipment.

[0024] 6. High degree of automation: The PLC control system enables the automated operation of the entire diversion process, reducing manual intervention and improving the intelligence level of the production line.

The rotation cycle is set by the control system, typically once every 2 seconds.

[0051] Workflow: Bottles enter the small turntable 2 from conveyor belt 1. The turntable rotates 36 degrees and stops. The gripping mechanism 5 grabs the bottle. The transition port blocking lifting mechanism 6 descends. The gripping translation mechanism 7 moves the bottle to the main turntable 3. The transition port blocking lifting mechanism 6 rises.

To improve durability, key moving parts can be made of stainless steel or have a surface-hardened finish. In addition, an automatic centralized lubrication system can be added to the bearing housings and guide rails to reduce daily maintenance workload.
