Description

Technical Field

[0001] The utility model relates to the technical field of ampoule bottle production, in particular to a tray pushing mechanism. Background Art

[0002] In the medical, food and other industries that require strict hygiene control, sterilization is an important step to ensure product safety and sterility. As a commonly used equipment in these industries, sterilization carts are usually used to load trays to be sterilized and are processed by specific sterilization equipment. However, after the sterilization process is completed, how to efficiently and safely remove the multi-layer trays in the sterilization cart has always been a problem that needs to be solved. Traditional tray removal methods mostly rely on manual operation, which is not only inefficient, but also easy to cause secondary contamination during operation, affecting the sterility of the product. Especially when handling a large number of trays, manual operation is not only labor-intensive, but also difficult to ensure the accuracy and consistency of the operation. In order to solve the above problems, some automated tray removal devices have appeared on the market, but these devices are often complex in structure, cumbersome in operation, and poor in adaptability to sterilization carts, and it is difficult to meet the needs of sterilization carts of different specifications and sizes. Therefore, it is of great significance to develop a tray pushing mechanism with simple structure, convenient operation and strong adaptability to improve the efficiency and safety of tray removal in sterilization carts. Utility Model Content

[0003] In order to solve the problems existing in the background technology, the utility model proposes a tray pushing mechanism. Through the cooperation of a tray pushing plate movably arranged on a frame, a retractable push rod, and a lifting drive device and a retractable drive mechanism, the tray pushing mechanism can realize the efficient and safe removal of multi-layer trays in the sterilization vehicle, providing strong support for sterilization work in the medical, food and other industries.

[0004] The utility model is realized through the following technical scheme: a tray pushing mechanism comprises a frame, on which a tray pushing mechanism for horizontally pushing multiple layers of trays in a sterilization vehicle is arranged; the tray pushing mechanism comprises a tray pushing platform movably arranged on the frame, on which a telescopic push rod is arranged, and on which a lifting drive device for driving the tray pushing plate to be lifted and lowered is arranged on the frame, and the lifting drive device drives the tray pushing platform to be lifted and lowered to the height position of each layer of trays; on the tray pushing platform, a telescopic drive mechanism for driving the push rod to be extended and retracted is arranged, and the telescopic drive mechanism drives the push rod to move horizontally to push the tray in the sterilization vehicle away from the sterilization vehicle.

[0005] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0006] Preferably, the lifting drive device is a synchronous belt lifting mechanism and is equipped with an independent driving source, the driving source is a servo motor, the lifting drive device includes a lifting guide rail and a lifting belt conveyor arranged on the frame, a lifting seat is arranged on the synchronous belt of the lifting belt conveyor, a lifting slider cooperating with the lifting guide rail is arranged on the lifting seat, the push plate is arranged on the lifting seat, and the lifting belt conveyor drives the push plate to lift and lower along the lifting guide rail.

[0007] Preferably, the telescopic driving mechanism includes a first synchronous belt mechanism, a first telescopic guide rail, a second synchronous belt mechanism, and a second telescopic guide rail which are arranged on a push plate along a pushing direction of the push rod, the first synchronous belt mechanism is connected to a servo motor, a first telescopic movable seat is arranged on the synchronous belt of the first synchronous belt mechanism, a first telescopic sliding block which cooperates with the first telescopic guide rail is arranged on the first telescopic movable seat, the second synchronous belt mechanism and the second telescopic guide rail are arranged on the first telescopic movable seat, the push rod is arranged on the synchronous belt of the second synchronous belt mechanism through a synchronous belt clamp, a second telescopic sliding block which cooperates with the second telescopic guide rail is arranged on the push rod, and the synchronous belt of the second synchronous belt mechanism is also connected to the push plate through a synchronous belt clamp.

[0008] Preferably, a plurality of the push rods and telescopic drive mechanisms are arranged side by side, and the plurality of telescopic drive mechanisms share one servo motor.

[0009] Preferably, a push plate is provided at the end of the push rod, and the push plate is arranged perpendicular to the push rod.

[0010] The beneficial effects of the utility model are mainly reflected in the following aspects:

[0011] (1) Improve operational efficiency: Through the automated tray pushing mechanism and lifting drive device, the tray pushing mechanism can quickly and accurately lift to the height of each layer of trays, and drive the push rod to move horizontally through the telescopic drive mechanism to push the tray out of the sterilization vehicle. This process does not require manual intervention, which greatly improves the operational efficiency of tray removal; at the same time, it reduces the difficulty of operation. Traditional tray removal methods rely on manual operation, which is labor-intensive and inefficient. The tray pushing mechanism greatly reduces the labor intensity of operators through automated operation, allowing them to focus on other more important work; the tray pushing mechanism adopts a modular design, and components such as the tray pushing plate and push rod can be adjusted as needed to adapt to sterilization vehicles of different specifications and sizes. This design makes the tray pushing mechanism highly adaptable and flexible, and can meet the needs of different industries.

[0012] (2) The synchronous belt lifting mechanism and servo motor are used as the lifting drive device to ensure the accuracy and stability of the lifting of the push plate. The high-precision control of the servo motor enables the push plate to be accurately lifted to the height position of each layer of the pallet, thereby improving the accuracy and reliability of the operation.

[0013] (3) Efficient telescopic drive: The telescopic drive mechanism adopts a dual synchronous belt mechanism and dual telescopic guide rail design, and is driven by a servo motor to achieve rapid and smooth telescopic movement of the push rod. This design not only improves the movement efficiency of the push rod, but also ensures the stability of the push rod during the telescopic process, avoiding damage to the pallet or operation failure caused by shaking or deviation of the push rod.

[0014] (4) Multiple push rods in parallel operation: Multiple push rods and telescopic drive mechanisms are arranged side by side, and multiple telescopic drive mechanisms share one servo motor. This design not only improves the space utilization of the equipment, but also reduces costs. At the same time, the parallel operation of multiple push rods can push multiple trays at the same time, further improving the operating efficiency. A push plate perpendicular to the push rod is set at the end of the push rod, which can better fit the bottom of the tray and ensure the stability and safety of the tray during the pushing process. At the same time, the design of the push plate can also reduce the friction between the tray and the push resistance, and improve the pushing efficiency; due to the modular design and adjustable components, this tray pushing mechanism can adapt to sterilization carts of different specifications and sizes. Whether it is a large or small tray, it can be adapted by adjusting the position and number of the push plate and push rods, which improves the versatility and flexibility of the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, a tray pushing mechanism comprises a frame, on which is installed a tray pushing mechanism for horizontally pushing multiple layers of trays in a sterilization trolley; the tray pushing mechanism comprises a tray pushing platform 11 movably installed on the frame, on which is installed a retractable push rod 9, and on which is installed a lifting drive device for driving the tray pushing platform 11 to rise and fall, and the lifting drive device drives the tray pushing platform 11 to rise and fall to the height position of each layer of trays; on the tray pushing platform 11, a telescopic driving mechanism for driving the push rod to extend and retract is installed, and the telescopic driving mechanism drives the push rod to move horizontally to push the tray in the sterilization trolley away from the sterilization trolley.

[0026] The lifting drive device 4 is a synchronous belt lifting mechanism and is equipped with an independent driving source, which is a first servo motor 5. The lifting drive device includes a lifting guide rail 8 and a lifting belt conveyor 7 installed on the frame. A lifting seat is installed on the synchronous belt of the lifting belt conveyor, and a lifting slider matching the lifting guide rail is installed on the lifting seat. The push plate is installed on the lifting seat, and the lifting belt conveyor drives the push plate to lift and lower along the lifting guide rail. The specific lifting process is that the first servo motor drives the rotating shaft to rotate, and the rotating shaft drives the synchronous belts of the lifting belt conveyors 7 on both sides to move, thereby driving the lifting seat on the synchronous belt conveyor to move along the lifting guide rail, thereby driving the push plate platform 11 to lift and lower to the height position of each layer of the pallet.

[0027] The telescopic driving mechanism includes a first synchronous belt mechanism 13, a first telescopic guide rail 12, a second synchronous belt mechanism 15, and a second telescopic guide rail 14 installed on the push plate along the pushing direction of the push rod. The first synchronous belt mechanism is connected to a second servo motor 6. A first telescopic movable seat 16 is installed on the synchronous belt of the first synchronous belt mechanism. A first telescopic slider 20 matching the first telescopic guide rail is installed on the first telescopic movable seat 16. The second synchronous belt mechanism and the second telescopic guide rail are installed on the first telescopic movable seat. The push rod is installed on the synchronous belt of the second synchronous belt mechanism through a synchronous belt clamp 18. The second telescopic guide rail cooperates with the second telescopic slider 21, and the synchronous belt of the second synchronous belt mechanism is also connected to the push plate through the synchronous belt clamp 17, so as to realize pushing. The pushing process is: the second servo motor drives the first synchronous belt mechanism 13 to move, and then the synchronous belt of the first synchronous belt mechanism drives the first telescopic moving seat and the second synchronous belt mechanism to extend, so as to realize the first-level telescopic extension. Since the synchronous belt of the second synchronous belt mechanism is also connected to the push plate through the synchronous belt clamp 17, during the extension of the second synchronous belt mechanism, the synchronous belt of the second synchronous belt mechanism also rotates, so as to drive the push rod to extend, so as to realize the second-level telescopic extension.

[0028] There are multiple push rods and telescopic drive mechanisms arranged side by side, and multiple telescopic drive mechanisms share a second servo motor 6 through a transmission shaft 19. This design not only improves the space utilization of the equipment, but also reduces the cost. At the same time, multiple push rods can be operated in parallel to push multiple pallets at the same time, further improving the operating efficiency.

[0029] In addition, a tray pushing plate 10 is installed at the end of the push rod 9. The tray pushing plate 10 is installed perpendicular to the push rod, which can better fit the bottom of the tray and ensure the stability and safety of the tray during the pushing process. At the same time, the design of the tray pushing plate can also reduce the friction between the tray and the pushing resistance, and improve the pushing efficiency; due to the modular design and adjustable components, the tray pushing mechanism can adapt to sterilization vehicles of different specifications and sizes. Whether it is a large or small tray, it can be adapted by adjusting the position and number of the tray pushing plate and the push rod, which improves the versatility and flexibility of the equipment.

[0030] The operation process of this equipment is: place the sterilization cart on the mobile cart or AGV cart, push the cart to place the sterilization cart on the support frame, at this time, the blocking cylinder piston rod extends to position the sterilization cart on the support frame, and the No. 2 servo motor drives the push rod platform to move to the height between the sterilization cart pallet layers (at the same time, the No. 3 servo motor drives the roller to move to the same height), and the No. 1 servo motor drives the three push rods to extend at the same time to push a row of pallets onto the roller. At this time, the cylinder piston rod at the bottom of the roller conveyor extends to keep a certain distance between the roller and the sterilization cart to avoid scratches during movement. The No. 3 servo motor drives the roller conveyor to move to the set height. At this time, the roller conveyor starts and drives the pallet to transfer to the next process.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
