Description

Technical Field

[0001] The utility model relates to the technical field of product transportation equipment, in particular to a transfer trolley for a tray. Background Art

[0002] With the development of electronic technology, people have proposed the concept of electronic paper, which is also called digital paper. It is an ultra-thin and ultra-light display screen, which can be understood as a "display as thin as paper, soft and erasable". Before processing the electronic paper, it needs to be transported to a designated location by a transport cart, and then unloaded to the subsequent processing equipment; however, in order to realize the collective transportation of multiple electronic papers, multiple electronic papers need to be placed in the Tray first, and each electronic paper is separated by a separator to avoid damage to the electronic paper during transportation. When unloading, it is only necessary to unload the Tray from the transport cart one by one.

[0003] After the tray is unloaded, the electronic paper in the tray is taken out one by one, and the spacer paper is loaded into another tray. After the electronic paper is taken out, the tray with the spacer paper is placed on the stacking platform to support the tray. After multiple trays are stacked on the stacking platform, the stacking platform can be operated to transport the stacked trays out and transport them to the storage device for easy removal by the staff.

[0004] However, the volume of the tray is large, and when multiple trays are stacked together, the staff cannot lift them up for transportation. In order to facilitate the removal of the trays on the storage device and transport them, a transfer trolley is used; however, when the existing transfer trolley is used to transport the stacked trays, the trays are easily separated from the transfer trolley, thereby causing damage to the trays. Therefore, a tray storage mechanism is provided to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a detailed description of a tray transfer trolley of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1-2As shown, an embodiment of a tray transfer trolley of the utility model includes a frame 10581 and a plurality of universal wheels 10582 arranged at the bottom of the frame 10581, and a handrail 10583 is provided on the frame 10581. The staff pushes the handrail 10583 to push the frame 10581 to move; wherein, a pair of horizontally arranged and mutually parallel strip frames 10584 are provided on the top of the frame 10581, and the spacing between the strip frames 10584 on both sides is the same as the size of the tray 105, and a plurality of universal wheels 10582 for transferring the tray 105 are rotatably provided on the side where the strip frames 10584 on both sides are close to each other. 05, the support rollers 10585 are arranged in a horizontal array and are arranged on the same strip frame 10584 and between adjacent support rollers 10585. Under the action of the first transmission member 10586, the support rollers 10585 arranged on the same strip frame 10584 can rotate synchronously; after the Tray 105 is placed on the frame 10581, under the action of the support rollers 10585, the stacked Tray 105 can move on the frame 10581, so as to facilitate the adjustment of the position of the Tray 105. A shift lever 105813 for blocking the Tray 105 is provided on the side of the frame 10581 close to the handrail 10583, and a clamping component for clamping the Tray 105 is provided on the side of the frame 10581 away from the shift lever 105813; after the stacked Trays 105 are placed on the supporting rollers 10585, the Tray 105 is pushed to adjust the placement position. When the Tray 105 contacts the shift lever 105813, the Tray 105 is placed in the designated placement position, and the clamping component automatically clamps the Tray 105, so that in the process of pushing the frame 10581 to move, the Tray 105 can be stably transferred and transported to prevent the Tray 105 from detaching from the supporting rollers 10585 and causing damage to the Tray 105.

[0027] In order to enable the tray 105 to automatically adjust to the designated placement position, a fixed block 10588 is provided on the vehicle frame 10581, and a transmission shaft 10589 with an axially horizontal arrangement is provided on the fixed block 10588. The transmission shaft 10589 is placed between the strip frames 10584 on both sides, and the axial direction is perpendicular to the length direction of the strip frames 10584. The two ends of the transmission shaft 10589 are respectively fixedly connected to different support rollers 10585, so that the support rollers 10585 on both sides rotate synchronously. Under the action of the transmission shaft 10589, the support rollers 10585 on both sides can rotate synchronously. In addition, a mounting seat 105810 is also provided on the vehicle frame 10581, and a servo motor 105811 is installed on the mounting seat 105810. The output shaft of the servo motor 105811 is connected to one of the support rollers 10585 through a second transmission member 105812. After the servo motor 105811 is started, one of the support rollers 10585 is driven to rotate through the second transmission member 105812, and the support rollers 10585 on the strip frames 10584 on both sides are driven to rotate synchronously under the transmission of the first transmission member 10586 and the transmission shaft 10589, so as to drive the Tray 105 to move, thereby realizing the straightening of the Tray 105 placed on the support rollers 10585. In addition, guide plates 10587 for guiding the Tray 105 are provided on the tops of the strip frames 10584 on both sides. When the Tray 105 is moved by the support rollers 10585, the guide plates 10587 are used to guide and limit the Tray 105, so that the Tray 105 always moves in a straight line.

[0028] like Figure 3As shown, the Tray 105 includes a rectangular frame 10501 (the shape of the electronic paper is also rectangular), and a tray bottom 10502 is provided at the bottom of the frame 10501. The frame 10501 and the tray bottom 10502 are combined to form the Tray 105 for holding the electronic paper. In addition, a clamping groove 10503 for a clamping component to be clamped is provided at the bottom of the frame 10501. After the stacked Trays 105 are placed on the support roller 10585, the frame 10501 is placed on the support roller 10585. After the Tray 105 is stabilized, the clamping component is clamped into the clamping groove 10503, thereby clamping the Tray 105 placed on the support roller 10585, so that the stacked Trays 105 can be stably placed in the process of pushing the frame 10581 to move. In addition, a positioning protrusion 10504 is provided on the top of the frame 10501, and a positioning hole 10505 for the positioning protrusion 10504 to pass through is provided on the bottom thereof. When multiple trays 105 are stacked together, the positioning protrusion 10504 of the lower tray 105 will pass through the positioning hole 10505 of the upper tray 105, so that the multiple trays 105 can be stably stacked together.

[0029] like Figure 4As shown, the clamping component includes a fixing seat 105814 arranged on the frame 10581, and the fixing seat 105814 is placed on the side of the frame 10581 away from the armrest 10583, wherein a clamping block 105816 which can be automatically clamped into the clamping slot 10503 is provided on the fixing seat 105814; after the Tray 105 is placed firmly, the clamping block 105816 is automatically clamped into the clamping slot 10503, thereby clamping the Tray 105, so that the stacked Trays 105 are stably placed. Furthermore, a rotating shaft 105815 is provided on the fixing seat 105814, which is arranged horizontally in the axial direction and is perpendicular to the length direction of the strip frame 10584 in the axial direction. The clamping block 105816 is fixedly arranged with the rotating shaft 105815. The top of the clamping block 105816 is used to be clamped into the clamping slot 10503 to clamp the Tray 105. The clamping block 105816 swings on the fixing seat 105814 through the rotating shaft 105815, so that the clamping block 105816 can be clamped into or out of the clamping slot 10503. A spring 105819 for applying force to the card block 105816 is provided between the fixed seats 105814. The spring 105819 applies a thrust to the card block 105816 so that the card block 105816 is inserted into the card slot 10503. When a force is applied to the card block 105816 to disengage from the card slot 10503, the spring 105819 will be compressed. After the force on the card block 105816 stops, the card block 105816 automatically resets under the action of the compressed spring 105819, and the card block 105816 can be automatically inserted into the card slot 10503. In addition, a bevel 105820 is provided at the top of the block 105816. When the stacked trays 105 are conveyed to the support roller 10585, the tray 105 on the lowest layer contacts the bevel 105820 on the top of the block 105816, causing the block 105816 to swing automatically and the spring 105819 to be compressed. When the tray 105 is conveyed to contact the gear lever 105813, the block 105816 is aligned with the slot 10503. Under the action of the compression spring 105819, the block 105816 is automatically inserted into the slot 10503. In order to limit the block 105816, an arc-shaped slide groove 105818 is provided on the block 105816, and a fixed column 105817 is also provided on the fixed seat 105814, and one end of the fixed column 105817 is placed in the arc-shaped slide groove 105818. When the block 105816 swings on the fixed seat 105814 through the rotating shaft 105815, the fixed column 105817 slides in the arc-shaped slide groove 105818, and under the action of the fixed column 105817 and the arc-shaped slide groove 105818, the swing angle of the block 105816 is limited.Additionally, the card block 105816 may be disposed on the fixing seat 105814 via an elastic member (metal spring or torsion spring, etc.) so that the card block 105816 is elastically connected to the fixing seat 105814 , which can also achieve the goal of automatically inserting the card block 105816 into the card slot 10503 .

[0030] After the frame 10581 is pushed to the designated position, it can be connected to the storage device for storing multiple Trays 105. During the connection, a force is applied to the card block 105816 to disengage from the card slot 10503, thereby automatically unlocking the Tray 105. In order to facilitate the connection between the frame 10581 and the storage device, a positioning wheel 105821 is provided on the side of the frame 10581 away from the handrail 10583. The positioning wheel 105821 can be used to make the frame 10581 be connected to the storage device. When the frame 10581 is connected to the storage device, it can be better positioned; in addition, an armature 105822 for stable connection is provided on the side of the frame 10581 away from the handrail 10583. After the frame 10581 is positioned by the positioning wheel 105821, the frame 10581 is attracted to the electromagnet on the storage device through the armature 105822, thereby forming a closed magnetic circuit with the electromagnet, thereby realizing the connection between the frame 10581 and the storage device.

[0031] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0032] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
