Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to an automatic loading and unloading device for pallets on a cigarette pack transport vehicle. Background Technology

[0002] In the cigarette packaging transportation industry, traditional loading and unloading operations rely on manual handling or simple conveying equipment, which makes it difficult to improve loading and unloading efficiency, results in high labor intensity for workers, and cigarette packages are easily damaged during frequent handling, increasing logistics loss costs.

[0003] With the application of automation technology, existing automated cigarette pack loading and unloading systems mostly adopt fixed rails and rigid push rod structures. The guide mechanism has a narrow adjustment range, making it difficult to adapt to different sized carriages. The linkage stability between the drive unit and the carrier is poor, and goods are prone to shifting and jamming during transportation, affecting loading and unloading efficiency and equipment lifespan. While some adjustable rail solutions attempt to solve the adaptation problem, their complex structures and high maintenance costs, along with the multi-point independent motor-driven split conveyor mechanism, still suffer from poor synchronization. Furthermore, the rigid locking structure between the loading trolley and the drive unit lacks buffer adjustment, failing to cope with motion interference caused by deformation of the carriage floor, severely restricting the reliability and adaptability of the loading and unloading system. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automatic loading and unloading device for pallets of cigarette pack transport vehicles, which adopts a specific structure and can fully solve the above-mentioned problem.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An automatic pallet loading and unloading device for a cigarette pack transport vehicle includes a transport pallet, a transmission guide rail, and a drive device. The transmission guide rail is arranged along the longitudinal centerline of the upper surface of the vehicle floor. Side plates are provided on both sides of the vehicle floor and are parallel to the transmission guide rail. A sliding plate is provided inside the transmission guide rail. The sliding plate is driven by the drive device and slides along the transmission guide rail. A transport pallet is provided above the transmission guide rail. The two sides of the transport pallet are engaged in the side plates, and the transport pallet slides synchronously along the transmission guide rail through the sliding plate.

[0007] In a preferred embodiment, rollers are provided on the inner side of the side plate, and the two sides of the transport pallet are engaged inside the side plate and roll in contact with the rollers.

[0008] In a preferred embodiment, the two sides of the sliding plate are connected to first pulleys via rotating shafts. The first pulleys are engaged with the inner side of the transmission guide rail, allowing the sliding plate to slide along the transmission guide rail in a limited manner.

[0009] In a preferred embodiment, the drive device includes a drive motor located inside the sliding plate. The drive motor is connected to a drive gear via a drive shaft, and the drive shaft and drive gear are coaxially fixed to drive their rotation. The tail end of the drive motor is connected to a spiral power supply line, and the other end of the spiral power supply line is connected to the truck's power system.

[0010] In a preferred embodiment, the inner side of the transmission guide rail is provided with a toothed plate, and the drive gear meshes with the toothed plate.

[0011] In the preferred embodiment, an electric telescopic rod is provided on the inner side of the sliding plate, and a locking pin is connected to the end of the electric telescopic rod. A corresponding locking hole is provided on the bottom of the transport pallet, and the locking pin can be inserted into the locking hole after it extends out to achieve locking.

[0012] In the preferred embodiment, displacement sensors are provided on the inner side of the sliding plate and the bottom of the transport tray, and the displacement sensors are wirelessly connected to the electric telescopic pole to control the locking action.

[0013] In a preferred embodiment, a second pulley is provided at each of the four corners of the bottom of the transport pallet, and the second pulley makes rolling contact with the floor of the vehicle.

[0014] An automatic pallet loading and unloading device for a cigarette pack transport vehicle, which has the following advantages:

[0015] 1. The transmission guide rail is set along the longitudinal centerline of the carriage floor, and together with the parallel side plates on both sides, it forms a stable transportation guidance structure. Under the action of the drive device, the sliding plate slides along the transmission guide rail, driving the transport pallet to move synchronously, realizing the automated loading and unloading of cigarette packs. Compared with traditional manual handling or simple conveying equipment, it greatly improves loading and unloading efficiency, while reducing the labor intensity of workers, reducing the damage of cigarette packs caused by human operation, and effectively reducing logistics loss costs;

[0016] 2. Rollers on the inner side of the side plate roll in contact with the transport pallet, and second pulleys at the four corners of the bottom of the transport pallet roll in contact with the floor of the truck bed. These two rolling structures significantly reduce friction during the sliding process, making cigarette pack transportation smoother and further improving loading and unloading efficiency while reducing energy consumption. The first pulleys on both sides of the sliding plate, connected by a pivot shaft, are engaged with the inner side of the transmission guide rail, ensuring stable sliding of the sliding plate along the guide rail and preventing cargo jamming due to sliding deviation, thus improving the stability and reliability of the equipment operation.

[0017] 3. The drive unit adopts a transmission method in which the drive motor drives the drive gear through the drive shaft to mesh with the toothed plate on the inner side of the transmission guide rail. Compared with the traditional rigid push rod structure, this transmission method has stable power transmission, a wider adjustment range, and can adapt to the loading and unloading needs of different sized truck bodies. The spiral power supply line connected to the tail of the drive motor is connected to the truck's power system to provide stable power to the drive unit and ensure continuous operation of loading and unloading operations;

[0018] 4. The electric telescopic rod inside the sliding plate engages with the locking hole at the bottom of the transport pallet, achieving precise engagement under the control of the displacement sensor. At the same time, the coordinated work of the electric telescopic rod and the displacement sensor avoids the problem of poor synchronization caused by using multiple independent motor drives, thus improving the smoothness and stability of loading and unloading operations.

Detailed Implementation

[0025] As shown in Figures 1 and 2, an automatic pallet loading and unloading device for a cigarette pack transport vehicle includes a transport pallet 2, a transmission guide rail 5, and a drive unit 8. The transmission guide rail 5 is arranged along the longitudinal centerline of the upper surface of the vehicle floor 1. This arrangement ensures that the transport pallet 2 moves smoothly along the central axis of the vehicle during loading and unloading, preventing cigarette packs from tipping over or colliding due to deviation. Side plates 3 are provided on both sides of the vehicle floor 1 and are parallel to the transmission guide rail 5. The side plates 3 serve as auxiliary limiting devices, further ensuring the operational stability of the transport pallet 2. The transmission guide rail 5 is equipped with a sliding plate 6, which is driven by the drive device 8 and slides along the transmission guide rail 5. The sliding plate 6 serves as an intermediate carrier for power transmission, converting the power of the drive device 8 into linear motion. A transport pallet 2 is provided above the transmission guide rail 5. The two sides of the transport pallet 2 are engaged in the side plate 3, and the transport pallet 2 slides synchronously along the transmission guide rail 5 through the sliding plate 6, thereby realizing the automated loading and unloading of cigarette packs transported on the transport pallet 2, which greatly improves the loading and unloading efficiency and reduces the errors and losses caused by manual intervention.

[0026] Preferred solutions include Figure 1As shown, rollers 4 are provided on the inner side of the side plate 3. The two sides of the transport pallet 2 are engaged in the side plate 3 and roll in contact with the rollers 4. The rollers 4 effectively reduce the friction of the transport pallet 2 during the sliding process. When the sliding plate 6 moves the transport pallet 2, the rollers 4 can roll along with the transport pallet 2, making the sliding of the transport pallet 2 smoother, reducing energy loss, and also reducing the wear between the transport pallet 2 and the side plate 3, extending the service life of the equipment. In addition, it can better maintain the stability of the transport pallet 2 during loading and unloading, preventing the cigarette packs from shaking.

[0027] Preferred solutions include Figure 2 As shown, the sliding plate 6 has first pulleys 7 connected to both sides via rotating shafts. The first pulleys 7 engage with the inner side of the transmission guide rail 5, allowing the sliding plate 6 to slide along the transmission guide rail 5. The cooperation between the first pulleys 7 and the inner side of the transmission guide rail 5 forms a stable guiding structure, restricting the sliding plate 6's freedom in the horizontal direction, ensuring it can only slide along the direction of the transmission guide rail 5. When the drive device 8 is working, the first pulleys 7 can roll within the transmission guide rail 5, not only ensuring the sliding accuracy of the sliding plate 6 but also further reducing frictional resistance during the sliding process. This ensures that the sliding plate 6 can stably and efficiently transmit power to the transport pallet 2, preventing interruption or deviation of cargo transportation due to poor sliding.

[0028] Preferred solutions include Figure 3 As shown, the drive unit 8 includes a drive motor 801, which is located inside the sliding plate 6. The drive motor 801 is connected to a drive gear 803 via a drive shaft 802. The drive shaft 802 and the drive gear 803 are coaxially fixed to drive their rotation. The tail end of the drive motor 801 is connected to a spiral power supply cable 11, and the other end of the spiral power supply cable 11 is connected to the truck's power system. The drive motor 801 serves as a power source, providing power to the entire loading and unloading device. When the drive motor 801 starts, it drives the drive gear 803 to rotate via the drive shaft 802. The design of the spiral power supply cable 11 ensures that the drive motor 801 moves with the sliding plate 6 while stably providing power to it, avoiding the impact of wire tangling or pulling on equipment operation. The drive gear 803 meshes with the toothed plate 501 on the inner side of the transmission guide rail 5, converting the rotational motion of the drive motor 801 into the linear motion of the sliding plate 6. This gear-toothed plate transmission method has the advantages of accurate transmission ratio, high transmission efficiency, and reliable operation, and can provide a stable driving force for the sliding plate 6 to meet the loading and unloading needs under different working conditions.

[0029] Preferred solutions include Figure 3As shown, the inner side of the transmission guide rail 5 is provided with a toothed plate 501, and the drive gear 803 is meshed with the toothed plate 501. During the loading and unloading operation, the drive gear 803 rolls along the toothed plate 501, causing the sliding plate 6 to slide within the transmission guide rail 5. Because the tooth profile design of the gear and toothed plate can ensure good meshing accuracy, it can effectively reduce power loss and improve transmission efficiency during power transmission, while ensuring the smooth movement of the sliding plate 6. This ensures that the cigarette packs on the transport pallet 2 will not shift or shake during transportation due to unstable power transmission.

[0030] Preferred solutions include Figure 2 and Figure 4 As shown, an electric telescopic rod 9 is provided on the inner side of the sliding plate 6. A locking pin 10 is connected to the end of the electric telescopic rod 9. A corresponding locking hole 13 is provided on the bottom of the transport pallet 2. The locking pin 10 can be inserted into the locking hole 13 after extending. During actual loading and unloading, when the sliding plate 6 needs to move the transport pallet 2, the electric telescopic rod 9 extends after receiving a control signal, pushing the locking pin 10 into the locking hole 13 at the bottom of the transport pallet 2, firmly connecting the sliding plate 6 and the transport pallet 2, allowing them to move synchronously. When the loading and unloading operation is completed or when it is necessary to separate the sliding plate 6 and the transport pallet 2, the electric telescopic rod 9 shortens, causing the locking pin 10 to exit from the locking hole 13, thus separating the two. This locking method is simple to operate, reliable in connection, and allows for flexible control of the connection and separation of the sliding plate 6 and the transport pallet 2 according to actual needs. It also buffers the impact of deformation of the carriage floor 1 to a certain extent, ensuring the smooth progress of loading and unloading operations.

[0031] Preferred solutions include Figure 2 and Figure 4 As shown, displacement sensors 12 are correspondingly installed on the inner side of the sliding plate 6 and the bottom of the transport pallet 2. The displacement sensors 12 are wirelessly connected to the electric telescopic rod 9 to control the locking action. The displacement sensors 12 monitor the relative position of the sliding plate 6 and the transport pallet 2 in real time. When the position of the two reaches the preset locking condition, the displacement sensor 12 transmits a signal to the electric telescopic rod 9, controlling the electric telescopic rod 9 to extend, so that the locking pin 10 inserts into the locking hole 13 to achieve locking. When a signal that separation is required is detected, the displacement sensor 12 sends a signal again, controlling the electric telescopic rod 9 to shorten, so that the two separate. Through this automated control method, the accuracy and automation of loading and unloading operations are improved, errors that may occur in manual operation are avoided, and the sliding plate 6 and the transport pallet 2 are accurately connected and separated at the appropriate time, ensuring the safety and stability of loading and unloading operations.

[0032] Preferred solutions include Figure 4As shown, second pulleys 14 are provided at the four corners of the bottom of the transport pallet 2, and the second pulleys 14 roll in contact with the floor 1 of the carriage. The setting of the second pulleys 14 further reduces the friction between the transport pallet 2 and the floor 1 of the carriage. During the movement of the transport pallet 2 driven by the sliding plate 6, the second pulleys 14 can roll freely on the floor 1 of the carriage, making the movement of the transport pallet 2 easier and more flexible. At the same time, the four second pulleys 14 are evenly distributed at the four corners of the bottom of the transport pallet 2, which can effectively distribute the weight of the transport pallet 2 and the cigarette packs it carries, avoiding damage to the floor 1 of the carriage or tilting of the transport pallet 2 due to excessive local stress, ensuring the stability of the transport pallet 2 during the entire loading and unloading process, and providing a reliable guarantee for the safe transportation of cigarette packs.
