Description

Technical Field

[0001] The utility model relates to the technical field of warehousing and logistics equipment, in particular to a fork mechanism of a multi-basket material box vertical warehouse stacker. Background Art

[0002] Currently, the electronics industry has a wide variety of products, and the efficiency of using traditional freight vehicles for transportation, operation, and storage is extremely low. In order to improve operational efficiency and reduce manual labor intensity, some factories use multi-basket material box vertical warehouse stacker systems for material turnover. Stackers are key lifting devices in high-rise warehouses. Stackers generally have multiple cache locations. Stackers use fork mechanisms to transport material boxes, store them in cache locations, or transport them from cache locations to processing stations. This process requires the stacker to use a cylinder to drive the fork mechanism to rotate and adjust the position. However, the cylinder drive rotation is prone to shaking, changing the position of the transferred material box, causing errors, and resulting in the material box being unable to be placed in the cache location. In addition, the fork mechanism of the current multi-basket material box vertical warehouse stacker needs to frequently clamp and release the material box during the material box transfer process. The structure is complex and the operation process is cumbersome, which affects the logistics transfer efficiency. Utility Model Content

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0031] Please refer to Figure 1 and 2 An embodiment of the present utility model provides a fork mechanism of a multi-basket material box vertical warehouse stacker, which is applied to a palletizer and mainly includes a bracket 1, a rotating platform 2 and a cargo platform 3.

[0032] The bracket 1 is generally installed on a vertical slide rail on one side of the palletizer frame to support and install the rotating platform 2 and the cargo platform 3.

[0033] like Figure 3 As shown, the bracket 1 includes an L-shaped support frame 11 and a horizontal mounting plate 12 . The horizontal mounting plate 12 is arranged on the horizontal side of the support frame 11 , and the rotating platform 2 and the cargo platform 3 are installed on the horizontal mounting plate 12 .

[0034] In some embodiments, in order to facilitate the installation of the fork mechanism of the multi-basket material box vertical warehouse stacker on the palletizer, the bracket 1 also includes a vertical mounting plate 13, which is U-shaped. The vertical mounting plate 13 is arranged on the vertical side of the support frame 11, and the bracket 1 is installed on the vertical slide rail of the palletizer through the vertical mounting plate 13.

[0035] The rotating platform 2 mainly includes a first motor 21, a gear mechanism and a rotating base 22. The rotating base 22 is rotatably mounted on the bracket 1. The first motor 21 is connected to the gear mechanism, and the gear mechanism is connected to the rotating base 22 to drive the rotating base 22 to rotate around the vertical axis.

[0036] Specifically, the gear mechanism includes a driving gear 23 and a driven gear 24, and the driving gear 23 and the driven gear 24 are both horizontally arranged and rotatably mounted on the upper surface of the bracket 1. The driving gear 23 and the driven gear 24 are engaged, and the first motor 21 is mounted on the lower surface of the bracket 1. The first motor 21 is connected to the driving gear 23, and the rotating seat 22 is fixedly mounted on the upper part of the driven gear 24.

[0037] like Figure 2 and 3 As shown, the driving gear 23 and the driven gear 24 are specifically installed on the upper surface of the horizontal mounting plate 12, and the first motor 21 is installed on the lower surface of the horizontal mounting plate 12. The first motor 21 is connected to the driving gear 23 through a right-angle reducer 25. The right-angle reducer 25 is fixedly mounted on the lower surface of the horizontal mounting plate 12, with the input end connected to the first motor 21 and the output end connected to the driving gear 23. The first motor 21 drives the right-angle reducer 25 to transmit the power to the driving gear 23, and the driving gear 23 and the driven gear 24 are engaged for transmission, so that the driven gear 24 rotates, thereby driving the rotating base 22 to rotate around the vertical axis.

[0038] like Figure 3 and 4 As shown, the cargo platform 3 mainly includes a bottom plate 31 and two telescopic plates 32 arranged on both sides of the bottom plate 31. The inner ends of each telescopic plate 32 are respectively provided with a fixed barrier rod 35 that is fixedly connected and a movable barrier rod 34 that is rotatably connected. The movable barrier rod 34 is also connected to a second motor so as to be driven to rotate by the second motor.

[0039] The extension and retraction of the telescopic plate 32 can drive the movement of the two fixed bars 35 and the two movable bars 34. The telescopic plate 32 is typically a multi-stage electrically retractable plate, capable of multiple stages of extension and retraction along its length. The specific structure is conventional and will not be described in detail here. In this embodiment, the cargo platform 3 also includes a U-shaped outer frame 33. The base plate 31 is fixedly mounted to the bottom surface of the outer frame 33, and the two telescopic plates 32 are respectively disposed on the inner side surfaces of the outer frame 33. The telescopic plates 32 can extend and retract along the inner side surfaces of the outer frame 33.

[0040] Among them, the two fixed baffles 35 are horizontally arranged, the distance between the two fixed baffles 35 is smaller than the width of the stacked material box 100, the two baffles are located on the same horizontal line, and one end of each fixed baffle 35 is vertically fixedly connected to the inner side surface of one of the telescopic plates 32, and the other end extends toward the inner side surface of the other telescopic plate 32.

[0041] The outer side of the telescopic plate 32 is provided with a hinge seat 36. The movable blocking rod 34 is a bent rod with an obtuse angle. One end of the movable blocking rod 34 passes through the telescopic plate 32 and is hingedly connected to the hinge seat 36. The position of the telescopic plate 32 through which the movable blocking rod 34 passes is provided with a movable groove to prevent the telescopic plate 32 from affecting the rotation of the movable blocking rod 34. The second motor is fixed to the outer side of the telescopic plate 32 and connected to the movable blocking rod 34.

[0042] The second motor can drive the movable barrier 34 to be retracted and released. For example, in this embodiment, the second motor can drive the movable barrier 34 to rotate 90 degrees, that is, to rotate between a vertical state and a horizontal state. The movable barrier 34 rotates to a vertical state, which is the retracted state; and rotates to a horizontal state, which is the released state.

[0043] In order to ensure that the transferred box 100 moves in the predetermined area and reduce the deviation of the transferred box 100, side bars 37 are respectively provided on both sides of the bottom plate 31. The two side bars 37 are located between the two telescopic plates 32 and are parallel to each other. The distance between the two side bars 37 is slightly larger than the width of the transferred box 100.

[0044] After the transferred material box 100 enters the two telescopic plates 32 , it moves between the two side bars 37 so that the position of the transferred material box 100 entering and exiting the cargo platform 3 can be accurately controlled.

[0045] like Figure 1 As shown, the fork mechanism of a multi-basket material box vertical warehouse stacker of the present invention is installed on a vertical slide rail on one side of the stacker frame during operation. The other adjacent side of the stacker frame is arranged with a production line. The stacker frame has multiple buffer positions arranged continuously along the vertical direction. The buffer positions are generally rectangular frame structures. During operation, the stacker needs to use the fork mechanism of the multi-basket material box vertical warehouse stacker to transfer the material box 100 on the production line to a buffer position on the frame, and transfer the material box 100 from a buffer position on the frame to the production line.

[0046] The process of transferring the material box 100 on the production line to a buffer position on the rack is as follows:

[0047] First, the fork mechanism of the multi-basket material box vertical warehouse stacker is controlled to slide on the vertical slide rail to the height of the transferred material box 100 on the production line, and the first motor 21 drives the rotating seat 22 to rotate so that the two telescopic plates 32 are close to one end of the two movable blocking rods 34 and face the vertical direction of the production line;

[0048] Then, the two second motors are controlled to drive the two movable blocking rods 34 to rotate to a vertical state, and the two telescopic plates 32 are controlled to extend to both sides of the transferred material box 100 on the production line, so that the transferred material box 100 enters between the two telescopic plates 32; the two second motors are controlled to drive the two movable blocking rods 34 to rotate to a horizontal state, so that the transferred material box 100 is confined between the two movable blocking rods 34 and the two fixed blocking rods 35; by controlling the two telescopic plates 32 to retract, the two movable blocking rods 34 drive the rotated material box 100 to move onto the bottom plate 31;

[0049] Then, the fork mechanism of the multi-basket material box vertical warehouse stacker is controlled to slide on the vertical slide rail to the height of a cache position on the frame, and the first motor 21 drives the rotating seat 22 to rotate 90 degrees, so that the two telescopic plates 32 are close to one end of the two movable blocking rods 34 and face the cache position;

[0050] Then, by controlling the two telescopic plates 32 to extend into the buffer position, the two fixed blocking rods 35 drive the rotated material box 100 to move into the buffer position; then controlling the two second motors to drive the two movable blocking rods 34 to rotate to a vertical state, releasing the transferred material box 100;

[0051] Finally, the two telescopic plates 32 are controlled to retract from the cache position, and the transferred material box 100 is stored in the cache position.

[0052] It can be understood that the specific process of transferring the material box 100 on a cache position on the rack to the production line is basically the same as the process of transferring the material box 100 on the production line to a cache position on the rack. The only difference is the original position and the pre-storage position of the transferred material box 100, which will not be further explained here.

[0053] In this document, directional terms such as front, back, top, and bottom are defined based on the positions of components in the accompanying drawings and relative to each other, and are intended for clarity and convenience in describing the technical solution. It should be understood that these terms are relative and may vary depending on usage and placement. The use of these directional terms should not limit the scope of protection claimed in this application.

[0054] The above embodiments and features of the embodiments may be combined with each other unless there is a conflict. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
