Description

Technical Field

[0001] The utility model relates to a novel hooking device which is applied to a dense stereoscopic warehouse to realize material box picking and placing operations, and belongs to the field of logistics warehousing. Background Art

[0002] In the field of logistics and warehousing, automation and intelligent control technologies have developed rapidly. With the continuous increase in industrial and commercial land and labor costs, intensive three-dimensional storage systems are widely used because they can fully utilize space efficiency and reduce labor demand accordingly. The material box-type three-dimensional warehouse used in e-commerce, food, medicine, new energy, logistics and other industries can realize the automatic storage and management of boxed goods, thereby improving the utilization rate of warehouse space, work efficiency and management level.

[0003] At present, the automatic storage and retrieval of material boxes below 30kg mainly adopts methods such as Miniload stackers and box shuttles, which cannot take into account the use requirements of low cost and high efficiency at the same time. Especially in the case of narrow width of the stereoscopic warehouse aisle, the existing technology lacks an effective solution. For example, in the previously disclosed Chinese patent application, the publication number is CN115649730A, its first-level left and right moving claw mechanism is guided by a guide rail slider and driven by a synchronous belt; the second-level extended movement claw is fixed as a whole on the first-level movement claw moving part, and the second-level claw adopts a left and right rotation mechanism. The initial state is parallel to the width direction of the trolley. When the first-level claw moves to the leftmost end, the second-level claw rotates to the left, and the second-level claw changes from being parallel to the width direction of the trolley to being parallel to the length direction, thereby completing the extension action of the second-level claw; at this time, the end claw rotates upward to complete the hooking action, and vice versa, the hooking action to the right is the same.

[0004] The above-mentioned prior art adopts three groups of power components, and the overall structure is relatively complex and has a high failure rate, which is not conducive to use in narrow aisles with limited width. The process of implementing the storage and retrieval of material boxes on the shelves takes a long time and has low operating efficiency.

[0005] In view of this, this patent application is proposed. Utility Model Content

[0006] The automatic material box hooking trolley described in the utility model aims to solve the problems existing in the above-mentioned prior art and propose a low-cost and high-efficiency automatic storage and retrieval solution for small-load material boxes, so as to have storage operation functions on both sides in narrow alleys, thereby effectively improving space utilization and quickly and accurately completing the purpose of hooking and storing material boxes under the condition of limited alley width.

[0007] To achieve the above-mentioned design purpose, the automatic material box hook trolley includes a trolley frame composed of a trolley frame side plate fixedly connected to the trolley frame bottom plate, and a material box pallet for supporting and feeding the material box to slide back and forth along its surface is arranged on the trolley frame; the first-level hook claw drive assembly is installed and fixed to the trolley frame through the first-level hook claw drive fixing plate, and its driving end is coaxially connected to the first-level hook claw active synchronous pulley, and the first-level hook claw driven wheel assembly is fixed to the trolley frame bottom plate by bolts, and a first-level hook claw transmission synchronous belt is closed-loop wound between the first-level hook claw active synchronous pulley and the first-level hook claw driven wheel assembly, and a synchronous belt clamping plate is fixedly connected to the first-level hook claw transmission synchronous belt; the synchronous belt clamping plate is installed and fixed to the second-level hook claw assembly, and the second-level hook claw assembly carries and drives the hook claw to extend and retract in two horizontal directions to complete the material box picking and placing operation.

[0008] Furthermore, a secondary hook assembly is fixedly installed on the top of the synchronous belt clamping plate, and its bottom is fixedly connected to a hook motion slider that is slidably buckled on the primary hook motion guide rail, and the hook motion slider is horizontally connected and extended along the bottom plate of the trolley frame.

[0009] Furthermore, two groups of material box guide strips are arranged on both sides of the frame for providing guidance and limitation in the horizontal direction.

[0010] Furthermore, the secondary hook assembly includes a bracket, which is fixedly connected to a guide rail fixing seat, and the slide rails are fixed on both sides of the guide rail fixing seat. The sliders connected to the slide rails are respectively fixedly connected to a rack fixing plate and a hook fixing plate; the hook is installed on the hook fixing plate, and the rack is fixed to the rack fixing plate; the motor reducer coaxially connected to the gear at the driving end is fixed to the guide rail fixing seat, and the gear is meshingly connected to the rack.

[0011] In summary, the automatic box hooking trolley proposed in this application has the following advantages:

[0012] 1. This application can be used in conjunction with an aerial storage vehicle to quickly and efficiently complete the picking and placing of material boxes in both horizontal directions. It is suitable for use in lanes with limited width and can be applied to e-commerce warehousing and logistics industries, such as electronics, food, medicine, etc., in automatic warehousing scenarios with small goods.

[0013] 2. This application proposes a two-stage telescopic fork structure for narrow lane widths, which can complete the storage and retrieval of the material box in both horizontal directions when the ratio of the lane width to the material box length is 1.5, solving the technical problem caused by the high storage density of the material boxes on the shelves and the small spacing between adjacent material boxes (such as only 15mm, which makes it impossible to use a similar shuttle clamping claw mechanism). This application adopts a corresponding claw structure to hook the groove in the middle of the material box, and accordingly obtains a more flexible and effective solution.

[0014] 3. Compared with the clamping hook structure on both sides of the existing shuttle car, the overall structure of this application is more compact. There is no need to hook from the left and right sides of the material box. The spacing between the material boxes on the shelf can be 15mm, which significantly improves the storage density.

[0015] 4. The overall hook structure adopted in this application adopts a set of power components, and the energy consumption and failure rate are low. BRIEF DESCRIPTION OF THE DRAWINGS
