Description

Technical Field

[0001] This utility model relates to the field of material pushing attachment technology, and in particular to a material pushing device without a support. Background Technology

[0002] Flexible material pushing attachments for unloading pallets are a crucial component of intelligent loading equipment. Currently available equipment is not very effective at shaping and loading unloading pallets, nor at placing them from the forklift teeth to the ground. It cannot detect whether the material is properly shaped, leading to over-stacking, excessively long unloading goods that prevent the truck doors from closing, or damage due to over-shaping. Therefore, there is a need to design an electric unloading material pushing device to meet the requirements of flexibility, depth detection, high efficiency, and high reliability. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a trayless material ejection device. This invention has a reasonable structure, is easy to assemble, and features the ability to sense ejection force, flexibility, high efficiency, and high reliability. It is effective for shaping and loading trayless materials onto trucks and for placing trayless materials from the forklift teeth onto the ground.

[0005] To achieve the above objectives, the technical solution of this utility model is: a trayless material ejection device, comprising: The backplate assembly has several trayless forks mounted underneath it. A pusher mechanism is disposed in front of the backplate assembly and above the trayless forks; A fork-scissor mechanism is disposed between the back plate assembly and the push plate mechanism, with one end of the fork-scissor mechanism connected to the back plate assembly and the other end of the fork-scissor mechanism connected to the push plate mechanism; An electric cylinder is mounted behind the backplate assembly and is connected to a servo motor to power the forklift mechanism.

[0006] This utility model features a compact structure, ease of assembly, flexibility, sensing capabilities, high efficiency, and high reliability, providing an efficient and reliable solution for shaping and loading pallet-less materials onto trucks and for placing them on the ground. By precisely controlling the thrust and stroke of the push cylinder with a servo motor, the pusher mechanism can flexibly adjust the pushing force according to material characteristics and shaping requirements, achieving flexible operation. Simultaneously, the forklift mechanism design enhances the stability and load-bearing capacity of the device, ensuring that materials will not fall or be damaged due to uneven force during the pushing process.

[0007] In some embodiments, the ejector cylinder is mounted behind the backplate assembly via an ejector cylinder mounting base. One end of the ejector cylinder is connected to the ejector cylinder mounting base, and the other end is connected to the fork-scissor mechanism. This invention positions the ejector cylinder mounting base behind the backplate assembly. Compared to traditional hydraulic ejectors, the fixed end of the fork-scissor mechanism is mounted on the backplate assembly, minimizing the attachment's off-load distance and reducing the downward shearing moment of the load center on the forks under heavy loads. This significantly reduces the rigidity requirements of the forks, resulting in a lighter structure.

[0008] In some embodiments, the bottom of the pusher mechanism is provided with a plurality of guide wheels, and each guide wheel moves within the unsupported material fork. The guide wheels at the bottom of the pusher mechanism prevent the pusher assembly from sagging and affecting material shaping when it extends 1.5 meters. Furthermore, the pusher mechanism of this invention is supported on the fork by the guide wheels, reducing the instantaneous vibration caused by force changes when the pusher mechanism stops extending from the point of extension, resulting in a smoother delivery of goods.

[0009] In some embodiments, the backplate assembly is provided with a guide groove for the movement of the forklift mechanism. The design of this guide groove ensures the stability and accuracy of the forklift mechanism during movement, effectively preventing equipment wear or malfunctions caused by movement deviations. Simultaneously, the precise positioning of the guide groove also improves the working efficiency and reliability of the entire trayless material ejection device.

[0010] In some embodiments, material photoelectric sensors for detecting the real-time position of the material are provided on both sides of the backplate assembly. These sensors enable real-time monitoring of the material's position on the forks and feed this information back to the control system. Based on the received position information, the control system precisely controls the pushing distance and speed of the pusher mechanism, thereby ensuring that the stack of goods meets the shaping requirements. This design not only improves the accuracy of goods shaping but also avoids problems such as damage to goods or poor shaping results due to over-pushing or under-pushing.

[0011] In some embodiments, photoelectric sensors for detecting the real-time position of the pusher mechanism are provided on both sides of the backplate assembly. These photoelectric sensors can capture real-time position changes of the pusher mechanism and rapidly transmit this data to the control system. Based on the received pusher position information, the control system dynamically adjusts the operating parameters of the pusher mechanism, such as speed and acceleration, to ensure that the pusher mechanism maintains a stable and efficient state during the delivery of goods. This precise control method not only improves the efficiency of goods delivery but also greatly enhances the stability and safety of equipment operation, effectively reducing the risk of equipment failure due to abnormal operation of the pusher mechanism.

[0012] In some embodiments, roller assemblies are provided on both sides of the backplate assembly. The roller assemblies serve as guides for vertical movement.

[0013] In some embodiments, the palletless forks are detachably connected to the backplate assembly. This detachable connection design greatly facilitates the installation, disassembly, and subsequent maintenance of the equipment. When the forks wear out or need to be replaced to accommodate different cargo sizes, workers can quickly and easily remove the forks from the backplate assembly and install suitable new forks without having to perform a large-scale disassembly of the entire device. This effectively saves time and labor costs and improves the flexibility and maintenance efficiency of the equipment.

[0014] The working principle of this utility model is as follows: When the forks pick up goods, the forklift mechanism is in the retracted state and the goods are close to the push plate mechanism. When the goods reach the designated position, the servo motor is activated, and the servo motor drives the push cylinder to provide power to the forklift mechanism. The forklift mechanism transmits the power to the push plate mechanism, which pushes the goods forward until they are disengaged from the forks. After the goods are in place, the push plate mechanism continues to push forward to shape the material until the push torque reaches the designated value. Then, the push plate mechanism retracts to complete the material shaping.

[0015] In summary, the beneficial effects of this utility model are: This utility model features a compact structure, ease of assembly, flexibility, sensing capabilities, high efficiency, and high reliability, providing an efficient and reliable solution for shaping and loading pallet-less materials onto trucks and for placing them on the ground. By precisely controlling the thrust and stroke of the push cylinder with a servo motor, the pusher mechanism can flexibly adjust the pushing force according to material characteristics and shaping requirements, achieving flexible operation. Simultaneously, the forklift mechanism design enhances the stability and load-bearing capacity of the device, ensuring that materials will not fall or be damaged due to uneven force during the pushing process.

[0016] This invention places the electric cylinder mounting base behind the back plate assembly. Compared with the traditional hydraulic pusher, the fixed end of the scissor mechanism is mounted on the back plate assembly, which minimizes the load-loss distance of the attachment, reduces the downward shearing torque of the load center on the fork when the fork is under heavy load, greatly reduces the rigidity requirements of the fork, and makes the structure lighter.

[0017] This invention features guide wheels at the bottom of the pusher mechanism to prevent the pusher assembly from sagging and affecting material shaping when it extends 1.5 meters. Furthermore, the pusher mechanism is supported on the forks by the guide wheels, reducing the instantaneous vibration caused by force changes when the pusher mechanism stops extending, resulting in smoother delivery of goods.
