[0002] In the modern warehousing and logistics industry, stacker is a common automated equipment, widely used in warehouses, distribution centers and other places for efficient storage and retrieval of goods. Stacker refers to a special crane that uses a fork or a skewer as a picking device to grab, transport and stack or pick and place unit goods from high-rise shelves in warehouses, workshops, etc.

[0003] Stacking crane, also known as stacker, is the most important lifting and transportation equipment in the stereoscopic warehouse. Stacker usually adopts a single-station design, that is, it can only handle one cargo position at a time, or adopts a double-station design, which can only pick up and place cargo in the horizontal direction, which limits the work efficiency to a certain extent, especially when it is necessary to handle multiple cargo positions at the same time, it cannot meet the use needs at one time. For this reason, it is necessary to provide a four-station stacker with an upper and lower double-station design, which can pick up and place horizontal and vertical cargo at the same time, and adopt a liftable cargo platform to adjust the cargo space according to the cargo size, so as to adapt to the pick-up and placement of various cargoes and improve work efficiency.

[0021] Hereinafter, an embodiment of a four-station stacker of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 A four-station stacker according to an embodiment of the utility model is shown, comprising a stacker gantry 1: a horizontal pulley 2 is fixedly installed at the bottom of the stacker gantry 1, a double-station cargo bin 3 is installed in the inner cavity of the stacker gantry 1, a double-station cargo platform 4 is arranged below the double-station cargo bin 3, two limiting tubes 11 are fixedly connected to both sides of the top of the double-station cargo platform 4, two limiting rods 12 are fixedly connected to both sides of the bottom of the double-station cargo bin 3, the limiting rods 12 are slidably connected to the surface of the limiting tubes 11, and the limiting rods 12 are slidably connected to the surface of the limiting tubes 11. The coordinated use of the tube 11 and the limiting rod 12 plays a limiting and guiding role on the double-station cargo platform 4, making the double-station cargo platform 4 more stable and reliable during the lifting process. A fixed box 5 is fixedly connected to the center of the bottom of the double-station cargo warehouse 3. The inner cavity of the fixed box 5 is provided with a lifting assembly 6. The lifting assembly 6 includes a lifting column 61 fixedly connected to the front and rear sides of the top of the double-station cargo platform 4. The top of the lifting column 61 is fixedly connected to a rack 62. The inner cavity of the fixed box 5 is rotatably connected to a rotating rod 63. The front and rear ends of the movable rod 63 are both passed through the outside of the fixed box 5 and fixedly connected with a gear 64, which meshes with the rack 62. A stepper motor 7 is fixedly installed on the right side of the fixed box 5. A worm 8 is rotatably connected to the inner cavity of the fixed box 5. The right end of the worm 8 passes through the right side of the fixed box 5 and is fixedly connected to the output shaft of the stepper motor 7. A worm wheel 9 is fixedly connected to the surface of the rotating rod 63, which meshes with the worm wheel 9. The front and rear sides of the top of the double-station cargo compartment 3 are both fixedly connected with a limiting sleeve 65. The rack 62 is slidably connected to the inner cavity of the limit sleeve 65, and the electric forks 10 are fixedly installed on both sides of the bottom of the inner cavity of the double-station cargo warehouse 3 and both sides of the top of the double-station cargo platform 4. Through the coordinated use of the stepping motor 7 and the worm 8, the worm wheel 9 is driven to rotate, so that the rotating rod 63 rotates. At the same time, the coordinated use of the worm 8 and the worm wheel 9 has a check effect on the rotating rod 63, thereby preventing the rotating rod 63 from rotating by itself and causing the double-station cargo platform 4 to slip.

[0023] Working principle: When the utility model is used, the user drives the double-station cargo bin 3 up and down through the stacker gantry 1, and drives the stacker gantry 1 and the double-station cargo bin 3 to move to the corresponding storage position through the horizontal pulley 2, and takes and places the goods through the electric fork 10. During use, the double-station cargo bin 3 and the double-station cargo platform 4 can be used in conjunction to take and place goods in the two horizontal storage positions and the two vertical storage positions. During use, the user can adjust the double-station cargo platform 4 and the double-station cargo bin 3 according to the height of the goods. The spacing between them can be adjusted, so that the storage space of the double-station cargo platform 4 can be adjusted. When adjusting, the user turns on the stepper motor 7, and the stepper motor 7 drives the worm 8 to rotate, so that the worm wheel 9 drives the rotating rod 63 to rotate, and under the meshing transmission action of the gear 64 and the rack 62, the rack 62 and the lifting column 61 can be lifted up and down, so that the use height of the double-station cargo platform 4 can be adjusted up and down, and the spacing between the double-station cargo platform 4 and the double-station cargo warehouse 3 can be adjusted, so as to adapt to the needs of taking and placing goods of different heights.

[0024] To sum up: the four-station stacker, through the coordinated use of the stacker gantry 1 and the horizontal pulley 2, allows the double-station cargo bin 3 and the double-station cargo platform 4 to be lifted up and down in the inner cavity of the stacker gantry 1, and at the same time, through the coordinated use of the lifting assembly 6 and the stepper motor 7, the distance between the double-station cargo platform 4 and the double-station cargo bin 3 can be adjusted, thereby achieving the purpose of simultaneously picking up and delivering goods at four stations and adjustable cargo space.
