Moreover, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0023] Reference Figure 1 This invention proposes a method for preparing the sheath for tube seasonings, comprising the following steps: S100: Deliver the hose in the first position to the designated release position; S200: Under the action of gravity, the hose is released from a designated position. Due to the difference in structure or weight between the hose's port end and tail end, the hose's posture is automatically adjusted to a second posture with the port end facing upwards, and it is placed on the receiving and transmitting component in the second posture. S300: The clamping mechanism clamps and fixes the hose in the second position, and drives the receiving and transmission component to carry the clamped and fixed hose to the film-coating station for film coating.

[0024] Specifically, in step S100, the hose in its first posture is transported to the designated release position by a conveying device (such as a conveyor belt). This first posture can be any initial posture of the hose during transport, such as horizontal or inclined placement. The conveying device operates continuously and stably to ensure the hose accurately reaches the release position, laying the foundation for subsequent posture adjustments and sheath preparation.

[0025] In step S200, when the hose reaches the designated release position, due to the structural or weight difference between the hose's inlet and outlet ends, the hose will automatically adjust its posture under the influence of gravity. For example, if the inlet end is lighter than the outlet end, the hose will rotate around a fulcrum, which can be the edge of the release position, causing the inlet end to gradually face upwards, eventually adjusting to a second posture with the inlet end facing upwards. This posture adjustment process requires no additional power device or complex mechanical structure; it can be completed solely based on the hose's own characteristics, making it simple and reliable. After adjusting its posture, the hose falls onto the receiving and transmitting component in the second posture. The receiving and transmitting component can be a tray or conveyor belt with a certain degree of elasticity and cushioning performance, which can smoothly support the hose and prevent damage to the hose during the descent.

[0026] In step S300, after the hose is placed on the receiving and transferring component, the clamping mechanism begins to operate. The clamping mechanism can be composed of two or more relatively movable grippers. Driven by a power unit, the grippers approach the hose and apply a suitable clamping force, firmly clamping and fixing the hose in its second position. The design of the clamping mechanism must ensure that the clamping force is moderate, preventing the hose from loosening or falling off during transfer without damaging it. It is understood that the power unit can be pneumatic, electric, etc. After the hose is clamped and fixed, the receiving and transferring component begins to move under the action of the drive unit, carrying the clamped and fixed hose to the film-coating station. When the hose reaches the film-coating station, the film-coating equipment begins the film-coating operation. The entire transfer process is smooth and accurate, ensuring that the hose enters the film-coating station in the correct position, guaranteeing high-quality film coating.

[0027] It is understood that the method of this invention utilizes the inherent structural or weight differences of the hose to achieve automatic posture adjustment, eliminating the need for manual intervention or complex mechanical adjustment devices. This significantly reduces the hose posture adjustment time and improves the efficiency of the entire sleeve preparation process. Simultaneously, the automated conveying and clamping mechanism can quickly and accurately transport the hose to the sleeve station, further increasing production speed. Compared to traditional methods requiring additional power units or complex mechanical structures for posture adjustment, the method of this invention has a simple structure, requires no additional energy consumption or complex maintenance, and reduces equipment and operating costs. Furthermore, the reduction in manual operation also lowers labor costs. Through precise posture adjustment and a stable conveying process, the hose enters the sleeve station in the correct posture, ensuring the accuracy and consistency of sleeve application and improving the packaging quality of the hose-based condiments. At the same time, it avoids errors and damage that may be caused by manual operation, further enhancing the overall product quality.

[0028] In some specific embodiments, the hose is a common plastic hose with a lightweight plastic cap at the nozzle and a sealed solid structure at the tail end, making the nozzle lighter than the tail end. First, the hose, initially positioned horizontally, is transported to a designated release position via a conveyor belt. The conveyor belt operates at a constant speed to ensure the hose reaches the release position accurately. Upon reaching the release position, due to the lighter weight at the nozzle, the hose rotates around the edge of the release position under gravity, gradually adjusting to a second position with the nozzle facing upwards. The adjusted hose then falls onto a receiving and transferring component below. This component is a conveyor belt with an elastic buffer layer, ensuring smooth hose support. Next, the clamping mechanism begins operation. This mechanism consists of two cylinder-driven grippers. When the hose falls onto the receiving and transferring component, a sensor detects the hose's position signal and transmits it to the control system. The control system then controls the cylinders to move the grippers closer to the hose and apply appropriate clamping force, firmly clamping and securing the hose. Finally, the receiving and conveying unit, driven by the motor, begins to operate, carrying the clamped and fixed hose to the film-coating station. Once the hose arrives at the film-coating station, the film-coating machine automatically performs the film-coating operation, completing the entire film-coating preparation process.

[0029] In other specific embodiments, the hose is a metal hose with a thin metal flange at the nozzle end and a thicker metal seal at the tail end, making the nozzle end lighter than the tail end.

[0030] The hose is conveyed to the designated release position in an arbitrary initial posture via a vibratory feeder. The vibratory feeder allows the hose to continuously adjust its posture during transport, ultimately arriving at the release position in a relatively random posture. Upon reaching the release position, due to the lighter weight of the hose end, gravity causes the hose to automatically adjust to a second posture with the end facing upwards, and it falls onto the receiving and conveying component below. The receiving and conveying component is a tray with grooves whose shape matches the hose's second posture, ensuring better hose fixation. The clamping mechanism consists of four motor-driven grippers arranged in a rectangular pattern. After the hose falls onto the receiving and conveying component, a photoelectric sensor detects the hose's position and feeds a signal back to the control system. The control system then controls the four motors to move synchronously, causing the grippers to move closer to the hose and apply a uniform clamping force, firmly holding and fixing the hose. Driven by a servo motor, the receiving and conveying component precisely conveys the hose along a preset track to the film-coating station. Once the hose reaches the film-coating station, the film-coating equipment performs the film-coating operation, completing the film-coating preparation.

[0031] This application further proposes that in a flexible condiment production line, the flexible tube is initially placed on a conveyor device in a horizontal position with its axis parallel to the horizontal plane, for example, lying flat on a conveyor belt. As the conveyor belt runs, the flexible tube is transported to a designated area. Upon reaching the designated position, due to the structural or weight difference between the tube's opening and closing ends—for example, the opening end has a lighter cap while the closing end is a sealed solid structure—the flexible tube automatically adjusts from a horizontal position to an upright position with its axis perpendicular to the horizontal plane under the action of gravity, i.e., the opening end facing upwards, and falls onto the receiving and conveying component below. If the flexible tube is initially in a sideways position, it will also adjust to an upright position under the action of gravity and its own structural weight difference. Utilizing the difference in gravitational torque generated by the structural or weight difference between the opening and closing ends of the flexible tube, the flexible tube rotates around a fulcrum when it is in a free-falling or freely rotating state, ultimately achieving an upright position with the opening end facing upwards. This embodiment is simple and direct, requiring no additional power unit or complex mechanical structure to achieve posture adjustment, reducing costs, improving production efficiency, and ensuring that the hose enters the subsequent film coating process in an accurate posture, thereby improving film coating quality.

[0032] This application further proposes that in the production of tube condiments, the upstream conveyor line uses a conveyor belt, on which the tubes, lying flat, are neatly arranged. The conveyor belt runs continuously, transporting the tubes to the end of the conveyor line, which is the designated release position. There is a certain height difference between the conveying plane of the conveyor line and the receiving plane of the receiving component; for example, the conveyor line is at a higher position, and the receiving component is at a lower position. When the tubes reach the end of the conveyor line, they fall from the conveying plane under the action of gravity onto the receiving component, ready for subsequent posture adjustment. By setting a height difference, the tubes are allowed to fall naturally under gravity, providing conditions for subsequent posture adjustment under gravity. This setup makes the tube transport and falling process simple and orderly, facilitates control of the tube position and the starting point of posture adjustment, and improves the stability and accuracy of the entire film preparation process.

[0033] It should be noted that during the preparation of the condiment tubing for film coating, the receiving and conveying component employs a belt conveyor mechanism with at least one clamping surface. After the tubing falls from its designated release position and adjusts to its second posture, it rests on the belt conveyor mechanism. During operation, the clamping surface of the belt conveyor contacts the tubing, providing constraint and stability, preventing the tubing from swaying or tipping during transport, and ensuring stable delivery to the film coating station. The belt conveyor mechanism fulfills the tubing transport function, while the clamping surface stabilizes the tubing's posture, ensuring accurate arrival at the film coating station. This improves the stability of the tubing during transport, reduces film coating errors caused by tubing swaying or tipping, and enhances film coating quality and production efficiency.

[0034] In the embodiments of this application, the belt conveyor mechanism receiving the transport component is configured as a double-layer belt structure during the preparation of the condiment sleeve on the flexible tube. When the flexible tube falls onto the belt conveyor mechanism in a second posture, the flexible tube is clamped in the gap formed between the upper and lower belts of the double-layer belt structure. For example, the upper and lower belts clamp the flexible tube with a certain pressure, and the flexible tube is stably transported as the belts move. During the transport process, the double-layer belt structure can effectively prevent the flexible tube from shaking or shifting. The double-layer belt structure applies clamping force to the flexible tube through the upper and lower belts, and uses the friction between the belts and the flexible tube to drive the flexible tube to move, while constraining the posture of the flexible tube. In addition, compared with a single-layer belt, the double-layer belt structure clamps the flexible tube more firmly, which can effectively avoid posture deviation of the flexible tube during transport, and improve the quality and efficiency of the sleeve preparation.

[0035] Specifically, in the preparation of the condiment tube sleeve, the gap between the upper and lower belts of the double-layer belt structure is designed to match the outer contour of the main body of the tube in its second posture. For example, if the tube body is cylindrical, the gap is designed as a corresponding cylindrical space. When the tube falls into the gap in its second posture, the upper and lower belts tightly clamp the main body of the tube. During the operation of the belt conveyor mechanism, friction drives the tube to move stably.

[0036] In other embodiments, the gap between the upper and lower belts of the double-belt structure is designed to fit the outer contour of the hose tail portion in the second posture. For example, the hose tail portion may have a special shape, such as a square protrusion, and the gap is designed accordingly. When the hose falls into the gap, the upper and lower belts clamp the tail portion. As the belts move, the hose is moved by the friction with the tail portion.

[0037] Understandably, the fitted gap shape of the double-layer belt structure ensures effective clamping of the main body of the hose, guaranteeing the hose's stable posture during delivery. Clamping the tail section further stabilizes the hose's posture, making it particularly suitable for hoses with special structures or weight distributions at the tail section, thus improving the quality of membrane preparation.

[0038] This application further proposes to install sensors, such as photoelectric sensors or vision sensors, along the transmission path during the preparation of the condiment tube sleeve. After the tube is clamped and fixed by the clamping mechanism, as it is transported to the sleeve station by the receiving and transmission component, the sensors monitor the tube's posture in real time. If the sensor detects a deviation in the tube's posture exceeding the allowable range, such as an excessively large tilt angle or deviation from a preset position, the sensor transmits a signal to the control system. The control system triggers an adjustment signal according to a preset program, adjusting the clamping force of the clamping mechanism or the transmission parameters of the receiving and transmission component; if the deviation is too large to adjust, a stop signal is triggered, stopping the equipment for inspection and adjustment. The sensors monitor the tube's posture in real time, converting the posture information into electrical signals and transmitting them to the control system. The control system determines whether to trigger an adjustment or stop signal based on preset thresholds, achieving real-time control and adjustment of the tube's posture. This allows for timely detection and adjustment of posture deviations, preventing sleeve failures due to posture issues, improving sleeve quality and production stability, and reducing the scrap rate.

[0039] To promptly identify hoses with non-compliant filling volumes, ensure product quality consistency, prevent substandard products from entering subsequent sealing processes, and improve overall production quality, this application further proposes that the filled and sealed hoses be conveyed to a weighing device via a conveying device. The weighing device accurately weighs each hose, records the weight data, and transmits it to the control system. If the hose weight does not fall within the preset range, the control system issues an alarm or marks the hose for further processing. The weighed hoses then proceed to step S100 for subsequent operations.

[0040] It should be noted that after filling and sealing, the tubing is transported to sterilization equipment, such as a high-temperature sterilization tunnel. Inside the tunnel, the material inside the tubing is heated. After a certain period of high-temperature treatment, any microorganisms that may be present inside the tubing are killed. The sterilized tubing, still at a high temperature, directly enters step S100. During transport and attitude adjustment, its residual heat is used to maintain a certain temperature environment, reducing heat loss. Specifically, the tubing is placed in the high-temperature sterilization tunnel, with the tunnel temperature set at no less than 85°C, for example, 90°C. The tubing remains in the tunnel for no less than 90 seconds, for example, 100 seconds. Under this high-temperature environment, any microorganisms that may be present inside the tubing are effectively killed. The sterilized tubing then enters the subsequent film preparation process. The high-temperature environment denatures and coagulates the proteins within the microorganisms, rendering them biologically inactive, thereby achieving the purpose of killing microorganisms and ensuring the hygienic quality of the condiments inside the tubing.

[0041] A second aspect of this invention provides a sleeve packaging device for tube condiments, comprising a sleeve preparation mechanism and an automatic sleeve packaging machine. The sleeve preparation mechanism applies any of the above-described methods for preparing sleeves for tube condiments. Specifically, the sleeve preparation mechanism includes the aforementioned techniques and structures for posture adjustment, conveying, clamping, and detection. The automatic sleeve packaging machine is located downstream of the sleeve preparation mechanism. After the tube has undergone posture adjustment and stable conveying in the sleeve preparation mechanism, it enters the automatic sleeve packaging machine. The automatic sleeve packaging machine automatically applies the sleeve to the tube, completing the entire sleeve packaging process. It can be understood that the sleeve preparation mechanism adjusts the tube to a suitable posture and stably conveys it to the automatic sleeve packaging machine, while the automatic sleeve packaging machine automatically completes the sleeve packaging action using a mechanical structure and control system, achieving efficient packaging of tube condiments. The two work together to complete the sleeve packaging of tube condiments. The entire device achieves automated production of sleeve packaging for tube condiments, improving production efficiency and product quality, reducing manual operation, lowering labor intensity and human error, and enhancing production stability and reliability.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
