A shelving system

Abstract

Automated storage racks are widely used due to their small footprint and high space utilization; however, existing racks require manual loading and unloading of materials, or rely on complex automated storage and retrieval systems. Factory material handling also requires manual retrieval. Automated loading and unloading, and automated material handling through information technology, are generally difficult to achieve in factories, primarily due to the lack of simple and practical automated racks. To address these issues, this invention provides an automated storage and unloading rack device that enables automatic control and loading / unloading. Furthermore, it allows for automatic material selection through information management.

Technical Field

[0001] This invention relates to the field of mechanical equipment, and in particular to a three-dimensional shelving system. Background Technology

[0002] Automated storage racks are widely used due to their small footprint and high space utilization. However, existing automated storage racks require manual loading and unloading of materials or rely on complex automated warehouse systems. Factory material handling also requires manual material retrieval. Automated loading and unloading, as well as automated material handling through information technology, are generally not feasible for factories due to the extreme difficulty. The main reason for this is the lack of simple and practical automated storage racks. Summary of the Invention

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] Material loading process:

[0039] The lifting device 2 is located on the ground, the material is placed in the material frame, and the material frame is placed on the lifting device 2.

[0040] Lifting device 2 rises: Start motor 287, which drives worm gear main 286, turbine main 285, connecting rod 284, worm gear pair 283, turbine pair 282, and lifting drive wheel 281 to rotate. Lifting drive wheel 281 interacts with lifting rack 15 on the end face of dovetail slide rail 17, driving lifting device 2 and material frame to rise. When the lower end of dovetail slider 22 of lifting device 2 reaches above the lever mechanism 4 of the empty shelf, the rise stops.

[0041] Rack 23 opens: Control latch pusher 27 drives latch 26 to extend, latch 26 pushes drive rack 23 to lift. Since drive rack 23 on dovetail slider 22 is hinged by two parallel rods, rack 23 tooth surface translates and reaches the position that can cooperate with drive wheel 39.

[0042] The lever mechanism 4 opens the telescopic support frame 33: At this time, the telescopic support frame 33 of the empty shelf is located at the front end and reverses upward to the vertical position under the action of the torsion spring 364, and is located outside the lever mechanism 4. The motor 287 reverses and drives the lifting device 2 to descend. The lower part of the dovetail slider 22 moves the handle of the lever head 41 and drives the upper arm 42, the lower arm 44, and the lever 45 to rotate until the upper arm 42 reaches the extreme vertical limit position. At the same time, the lever 45 pushes the telescopic support frame 33 to open.

[0043] Lifting device 2 presses telescopic support frame 33 to rotate: Lifting device 2 continues to descend, and pulley 34 on telescopic support frame 33 contacts the bottom of support plate 25. Under the action of support plate 25, pulley 34 drives telescopic support frame 33 to rotate downward.

[0044] Unloading to telescopic support frame 33: When the telescopic support frame 33 reaches the horizontal position, the pulley 34 enters the release notch 24 of the U-shaped frame 21, the telescopic support frame 33 lifts the material frame, and the telescopic support frame 33 and the material frame are released from the U-shaped frame 21.

[0045] The telescopic tray 33 moves the material frame into the shelf: The lifting device 2 continues to descend, the drive rack 23 reaches and acts on the drive wheel 39, the drive wheel 39 drives the main shaft gear 38 and the tray rack 35, and drives the telescopic tray 33 and the slide plate mechanism 36 to move the material frame into the shelf along the tray slide groove 32.

[0046] Lifting device 2 descends: Control latch pusher 27 drives latch 26 to retract, bracket device 3 continues to descend to the ground;

[0047] It is worth mentioning that when the lifting device 2 passes the lever mechanism 4 during its descent, the forearm 44 protrudes. Since the forearm 44 is hinged to the upper arm 42 and connected by the elastic body 43 to form a joint, the lifting device 2 will pull the forearm 44 to straighten it to avoid interference. After the lifting device 2 disengages from the lever mechanism 4, the lever mechanism 4 returns to its free state under the action of the elastic body 43 and the tension spring 46.

[0048] Material feeding process:

[0049] Lifting device 2 rises: Start motor 287, lifting drive mechanism 28 and lifting rack 15 work together to lift lifting device 2;

[0050] Remove the telescopic support frame 33 and the material frame on it: When the upper end of the drive rack 23 approaches the drive wheel 39 below the target shelf, control the locking tongue pusher 27 to drive the locking tongue 26 to extend, the locking tongue 26 pushes the drive rack 23 to lift the drive wheel 39, the drive wheel 39 drives the main shaft gear 38 and the support frame rack 35, and further drives the telescopic support frame 33 and the material frame on it to move out.

[0051] The telescopic support frame 33 and its loading frame are moved to the lifting device 2: when the telescopic support frame 33 reaches the outer limit position, it stops; after the lifting device 2 arrives, it lifts the loading frame on the telescopic support frame 33.

[0052] Lifting device 2 disengages from telescopic support frame 33: Lifting device 2 rises further, and telescopic support frame 33 rotates around slide plate axis 362 under the action of torsion spring 364, with pulley 34 closely attached to the bottom of support plate 25. Lifting device 2 continues to rise until telescopic support frame 33 rotates to a vertical position and disengages from telescopic support frame 33.

[0053] Lifting device 2 falls: After the lifting device 2 disengages from the telescopic support frame 33, the control motor 287 reverses and the lifting device 2 falls. At the same time, the control latch pusher 27 drives the latch 26 to retract until the lifting device 2 descends to the ground.
