Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal transport vehicle. Background Technology

[0002] During the processing of boards, steps such as laying, cold pressing, hot pressing, gluing, and edge trimming are required. Transport vehicles are needed to transfer the boards between these steps. Existing transport vehicles usually require manual unloading and can only be used for one method of placing boards, such as stacking them directly or placing them individually. However, since the board loading methods differ for each step, such as in the cold pressing step where boards are stacked together, but in other steps like hot pressing where individual boards are typically loaded and transported, the single stacking method of the transport vehicles is difficult to adapt to the different board loading methods for each step.

[0026] The conveying mechanism 2 is located on the top of the frame 1 and serves as a platform for placing and conveying sheet metal. The conveying mechanism 2 includes a plurality of rollers 21 spaced apart along the conveying direction, a plurality of rollers 22 spaced apart along the axial direction on each roller 21, and a conveying drive mechanism for driving the plurality of rollers 21 to rotate synchronously. The rollers 21 are rotatably connected to both sides of the frame 1, and the highest point of the rollers 22 is higher than the plane of the frame 1.

[0027] It should be noted that the conveying drive mechanism is an existing mechanism, which includes a transmission component and a drive motor. The transmission component can be composed of sprockets and synchronous belts. Two sprockets are provided on each roller 21. The sprockets on adjacent rollers 21 are connected by synchronous belt transmission. The drive motor is connected to one of the rollers 21. The drive motor can drive multiple rollers 22 to rotate synchronously through the transmission component.

[0028] A lifting mechanism 3 is located below the conveying platform and is used to lift the sheet metal above the conveying mechanism 2. The lifting mechanism 3 includes a lifting cylinder 31, multiple lifting rods 32, and a mounting plate 33. The mounting plate 33 is located below the conveying platform, and the multiple lifting rods 32 are fixed to the mounting plate 33, with the lifting rods 32 positioned at the gaps in the rollers 21 so that they can extend beyond the conveying platform when lifted. The lifting cylinder 31 is fixed to the crossbeam of the frame 1, and the telescopic end of the lifting cylinder 31 is connected to the bottom of the mounting plate 33. When sheet metal is loaded and unloaded, it is conveniently stacked on the conveying platform via the conveying mechanism 2.

[0029] The multi-layer board-laying rack assembly 4 includes frame bodies 41 located on both sides of the top of the vehicle frame 1 and an adjustment mechanism 42 for adjusting the distance between the two frame bodies 41. Several board-laying slots 411 are vertically spaced on opposite sides of the two frame bodies 41. The adjustment mechanism 42 includes a screw 422, a guide rod 423, a U-shaped mounting frame 421, and a first drive motor 424. The U-shaped mounting frame 421 is fixed to the outer top of the vehicle frame 1. The screw 422 is located in the middle of the U-shaped mounting frame 421, with one end connected to the vehicle frame 1. The frame 41 is rotatably connected, with its other end rotatably connected to the U-shaped mounting frame 421 and extending out of the U-shaped mounting frame 421 to connect to the first drive motor 424. A guide rod 423 is parallel to both sides of the screw 422, with one end connected to the frame 1 and the other end connected to the U-shaped mounting frame 421. The lower middle portion of the frame 41 is provided with threaded sleeves 425 threadedly connected to the screw 422, and the lower sides of the frame 41 are provided with sliding sleeves 426 movably fitted with the guide rods 423. Rotating the screw 422 moves the frame 41, and adjusting the distance between the two frames 41 accommodates the placement of plates of different widths. The frame also has a baffle 44 to block the insertion opening of the plate placement slot, and slots 43 for inserting the baffle 44 are correspondingly provided at the upper and lower ends of the inner side of the frame. Inserting the baffle 44 provides lateral restraint during the transport of stacked plates.

[0030] The rear limit plate 5 is set at the rear edge of the platform; the rear limit plate 5 is set with two horizontal intervals. When the plate is placed on the conveying platform, the rear limit plate 5 is used to limit the plate, which can ensure that the plate is aligned and the plate is not easy to fall off the conveying platform.

[0031] The ejection mechanism 6 is used to eject the sheet material from the multi-layer board rack assembly 4. The ejection mechanism 6 includes a push plate 62 and an ejection cylinder 61 that controls the extension and retraction of the push plate 62. The ejection cylinder 61 is fixed to the rear side of the middle part of the lifting plate 76, and the extension and retraction end of the ejection cylinder 61 passes through the lifting plate and connects to the push plate 62.

[0032] The lifting mechanism 7 is used to control the height of the pushing mechanism 6. The lifting mechanism 7 includes a drive shaft 71, a driven shaft 72, a sprocket 73, a transmission chain 74, and a second drive motor 75. A bracket 70 is provided at the rear end of the frame 1.

A lifting plate 76 is connected between the two transmission chains 74 near the side of the frame 1.

[0033] When the transport vehicle is used to transport stacked boards, the stacked boards are placed on the conveying platform of the conveying mechanism 2. The rear limiting plate 5 acts as a rear limiter. A baffle 44 can be inserted into the frame 41, and the width of the two frames 41 can be adjusted according to the width of the boards through the adjusting mechanism 42, which can act as a side limiter to prevent tipping during transportation. During transportation, the lifting mechanism 3 lifts the stacked boards as a whole above the conveying platform, making the transportation process more stable. When unloading the boards, the transport vehicle is placed on the lifting platform. After the conveying platform of the transport vehicle is aligned with the unloading platform, the lifting mechanism 3 retracts, and the conveying mechanism 2 moves to send the stacked boards to the corresponding unloading platform.

[0034] When the processing step is single-board feeding and conveying, the baffle 44 on the frame 41 is removed, and the width of the two frames 41 is adjusted according to the width of the board by the adjustment mechanism 42. The boards are then inserted into the placement slots of the frames 41 respectively. When the boards are unloaded, the transport vehicle is placed on the lifting platform so that each layer of boards corresponds to the board placement layer. Then, the position and height of the ejection mechanism 6 are adjusted by the lifting mechanism 7 to eject the corresponding boards.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
