[0001] The utility model relates to the technical field of trolleys, in particular to an automatic palletizing and discharging trolley. Background Art

[0002] Sheet material is a common material in the material market. According to different usage situations, the material requirements for sheet material are also different. During the processing and production of sheet material, it is necessary to transport and stack the sheet material. By stacking, the sheet material can be placed in an orderly manner, which is conducive to loading the sheet material. During the transportation and stacking process, in order to reduce manual operation and ensure efficiency, relevant mechanical equipment will be used to complete the corresponding work. At present, the automatic palletizing and discharging trolley is a new type of discharging equipment in sheet material processing equipment.

[0003] The existing discharging trolleys mainly have the following technical problems:

[0004] 1. The structure of the existing discharging trolley is relatively fixed. Usually, the tabletop is set according to the sheet material to be placed, and generally, components such as positioning and guiding are not equipped. There are requirements for the outer dimensions of the finished sheet material placed, and the adaptability is poor.

[0005] 2. The existing discharging trolley is not equipped with a palletizing device and cannot meet the stacking requirements of trapezoidal plates, rectangular plates, rhombic plates, and special-shaped plates at the same time. It cannot be flexibly typeset according to the finished products and cannot be adjusted in real time online.

[0006] 3. The existing discharging trolley needs to be used in combination with a discharging rack and a lifting table, and the structures of the discharging rack and the lifting table are relatively fixed, with high manufacturing costs, maintenance costs, and large floor areas. Content of the Utility Model

[0007] In view of the technical problems existing in the background art, the utility model provides an automatic palletizing and discharging trolley.

[0008] The technical solution for the utility model to solve the technical problems is as follows:

[0009] According to one aspect of the present utility model, an automatic palletizing discharging trolley is provided, which includes a discharging table surface, guide rods, a beating mechanism and a traveling mechanism. A plurality of positioning holes are formed in the upper surface of the discharging table surface, and the guide rods are respectively installed in the positioning holes. A plurality of the beating mechanisms are respectively arranged along the outer edge of the discharging platform. The beating mechanism includes a column connected to the discharging table surface, a lifting mechanism arranged on the column, a telescopic mechanism arranged on the lifting mechanism, and a beating assembly arranged at the front end of the telescopic mechanism. The traveling mechanism is arranged at the bottom of the discharging table surface. Among them, the plurality of positioning holes are used to enclose the stacking range of the sheet materials. The guide rods installed in the positioning holes play a guiding role when the sheet materials are blanked. The beating assembly is used to beat and align the stacked sheet materials to achieve the orderly placement of the sheet materials. The lifting mechanism and the telescopic mechanism are respectively used to drive the beating assembly to achieve lifting movement and telescopic movement, so as to facilitate the beating and alignment of sheet materials of various shapes and sizes. The traveling device is used for the movement of the trolley to facilitate the conveying of the sheet materials.

[0010] Further, an installation plate is arranged on the column, and the installation plate is connected to the edge of the discharging table surface, which is convenient for the assembly of the beating mechanism at the edge of the discharging table surface.

[0011] Further, the lifting mechanism includes a first linear slide rail and a first rack respectively vertically fixed on the column. A first slider is movably arranged on the first linear slide rail. A sliding plate is fixed on the first slider. A lifting motor is arranged on the sliding plate. A first gear meshing with the first rack is arranged at the output end of the lifting motor. When the lifting motor drives the first gear to rotate, the first gear can be lifted and moved on the first rack, and then drive the telescopic mechanism and the beating assembly installed at the front end of the telescopic mechanism to lift and move, so as to facilitate the beating assembly to reach the height of the stacked sheet materials. The first linear slide rail and the first slider form a vertical linear guide rail, which improves the stability of the lifting mechanism during movement. Preferably, there are two such vertical linear guide rails.

[0012] Furthermore, the telescopic mechanism includes a positioning arm, a telescopic motor and a second slider respectively fixed on the sliding plate. The flapping assembly is installed at the front end of the positioning arm. Inside the positioning arm, a second rack and a second linear slide rail are fixedly arranged. The output end of the telescopic motor is provided with a second gear meshing with the second rack. The second slider is slidably connected with the second linear slide rail. The telescopic motor drives the second gear to rotate, which can then drive the second rack engaged therewith to move back and forth. The second rack drives the positioning arm to move back and forth, realizing the back-and-forth movement of the flapping mechanism at the front end of the positioning arm to approach the sheet materials stacked on the discharge table. The second slider and the second linear slide rail form another linear guide. The second slider is fixed relative to the sliding plate, and the second linear slide rail moves back and forth on the second slider. To further ensure the stability of the second linear slide rail during movement, it is preferable to set two second sliders on the sliding plate to jointly support a second linear slide rail.

[0013] To save space and facilitate installation, an installation groove is provided inside the second linear slide rail, and the second linear slide rail is installed in the installation groove. In addition, a connecting plate can also be installed on the sliding plate, and the lifting motor can be installed on the sliding plate through the connecting plate.

[0014] Furthermore, limit blocks are respectively arranged at both ends of the positioning arm to limit the movement range of the positioning arm.

[0015] Furthermore, the flapping assembly includes a flapping driving device installed at the front end of the positioning arm and a stopper installed at the front end of the flapping driving device.

The shape of the stopper is mainly an arc surface on the front side, which can be a fan-shaped surface, a cylindrical surface, a semi-cylindrical surface, etc. The overall shape is preferably a cavity-shaped semi-cone upper part and a cavity-shaped semi-cylinder lower part fixedly arranged up and down, which is convenient for assembly and flapping of the sheet materials. Designing the cavity-shaped semi-cone upper part enables the stopper to move to a position aligned with the cavity-shaped semi-cylinder lower part under the action of the semi-cone even if there are sheet materials on the upper part during the upward movement.

[0016] Furthermore, an end mounting seat is arranged at the end of the positioning arm. A third linear slide rail is vertically arranged on the end mounting seat. A third slider is movably arranged on the third linear slide rail. The third linear slide rail and the third slider form another linear guide. The flapping driving device is fixedly connected with the third slider. A locking device is arranged on the third slider to lock the third slider on the third linear slide rail, which is convenient for fine-tuning the height of the stopper during the operation of the trolley.

[0017] Further, the traveling mechanism includes multiple pairs of wheel supports correspondingly arranged at the bottom of the discharging tabletop. Wheels are respectively installed on the wheel supports. Each pair of wheels is respectively connected to a synchronous shaft through a connecting sleeve. A trolley motor is arranged on one of the synchronous shafts. End caps are arranged on the outer sides of the wheel supports.

[0018] Further, it also includes a drag chain arranged on the discharging tabletop, which is convenient for the arrangement and movement of various cable harnesses and the like.

[0019] Further, it also includes a hard rail arranged through a backing plate. The wheels are adapted to the hard rail and are rollingly arranged on the hard rail, which is convenient for the reciprocating movement of the trolley.

[0020] Further, a corresponding controller can also be set for the automatic palletizing and discharging trolley. The controller is connected to each motor, driving device, etc., receives external control instructions, and controls each motor and driving device as required. It can also be linked with other systems of the sheet metal production line, such as the sheet metal nesting and conveying system, etc. According to the feedback information of the nesting and conveying system, it obtains information such as the shape and size of the sheet metal to be stacked. It obtains the sheet metal quantity information by setting a counter, obtains the control instructions for each motor and driving device based on the received information, and controls each motor and driving device to complete corresponding operations.

[0025] (4) Through the beating and alignment function of the beating mechanism, the present utility model is applicable to the palletizing and conveying of various types of finished sheet metals, and has strong applicability;

[0026] (5) The utility model installs the flapping drive device by setting a third linear slide rail and a third slider at the front end of the positioning arm to form a linear guide rail, which can realize the fine adjustment of the height of the stopper.

[0027] (6) After calculating and processing the feedback signals from other supporting systems on the sheet metal processing production line, the utility model generates corresponding instructions, and controls each motor and drive device according to the instructions to complete the alignment and flapping of the sheet metal. The mutual linkage between the mechanical and electrical components makes the palletizing process simpler and smoother, with high automation, easy to operate and maintain.

[0028] (7) The discharging trolley of the utility model combines the functions of palletizing and conveying. It does not require a discharging rack and a lifting table, greatly reducing the floor area and the equipment investment cost. At the same time, the discharging trolley can be linked between processes according to the requirements of factory digitization and intelligentization, and can be transmitted in multiple directions, being more flexible and maneuverable, with a high degree of integration.
