Description

Technical Field

[0001] This utility model relates to the field of cardboard box sorting technology, specifically a clamping device for sorting lightweight cardboard boxes. Background Technology

[0002] In modern logistics warehousing and cargo transfer centers, forklifts are the core equipment for handling and stacking palletized goods. However, traditional forklift forks are mainly used for picking up and lifting goods, such as cardboard boxes, and their function is relatively limited. When faced with scenarios that require quickly and accurately picking specific goods from densely stacked piles of goods, or handling non-standard goods of different sizes, traditional forklifts are inadequate. Operators need to repeatedly fine-tune the forklift position, which is not only inefficient and labor-intensive, but also poses a safety risk of damage or even tipping over due to operational errors.

[0003] To address the aforementioned issues, some auxiliary clamping devices installed on forklift forks have emerged in the market. However, existing devices often suffer from the following drawbacks: 1) Limited clamping dimension, typically only capable of clamping in one direction (e.g., the width direction), unable to simultaneously secure the goods in both the X and Y axes, resulting in insufficient stability; 2) Poor synchronization, where asynchronous action of multiple hydraulic cylinders can lead to arm tilting, uneven force application, and potential damage to the goods; 3) Cumbersome and unreliable connection and fixing methods with the forklift, affecting operational safety.

[0004] Therefore, there is an urgent need in this field for a sorting device that can be integrated into forklifts, is easy to operate, has stable and reliable clamping, and is highly adaptable, in order to improve the level of automation and operational efficiency of logistics sorting.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] Therefore, the purpose of this utility model is to provide a clamping device for sorting lightweight cartons. By setting mutually perpendicular X-axis clamping components and Y-axis clamping components, a grid-shaped clamping frame is formed, which can apply clamping force from the front, back, left, and right directions of the goods at the same time. This ensures that the cartons are subjected to multi-dimensional constraint forces during the picking and moving process, effectively preventing them from swaying back and forth or shifting left and right, and greatly improving the stability and safety of the handling process.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A clamping device for sorting lightweight cardboard boxes, comprising:

[0009] As a connecting base frame, the fork sleeve frame has two sets of cross frames symmetrically connected at the bottom, and two sets of mounting brackets are connected between the two sets of cross frames.

[0010] The bottom of the horizontal frame is connected to the vertical frame, and the horizontal frame and the vertical frame are set one-to-one and arranged in a grid pattern.

[0011] The X-axis clamping assembly is connected to the mounting bracket and provides clamping action in the X-axis direction.

[0018] As a preferred embodiment of the clamping device for sorting lightweight cartons described in this utility model, the locking assembly includes fixed frames connected to both sides of the fork sleeve frame end, with each pair of fixed frames arranged opposite to the other, and a positioning bolt connecting the two sets of fixed frames through the bolt, which is locked to the fixed frame by a positioning pin.

[0019] As a preferred embodiment of the clamping device for sorting lightweight cartons described in this utility model, the top of the fork frame is connected to a connecting frame, and an oil circuit control component is provided on the connecting frame.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] By setting mutually perpendicular X-axis clamping components and Y-axis clamping components, a grid-shaped clamping frame is formed, which can apply clamping force from the front, back, left and right directions of the goods at the same time.

[0024] The synchronization valve in the oil circuit control component ensures that the two hydraulic cylinders driving the same set of clamping arms can extend and retract synchronously, so that the two sets of opposite clamping arms can contact the side of the goods in parallel, avoiding the goods being squeezed, deformed or damaged due to one side being subjected to force first. This is especially important for transporting goods packaged in cartons, fragile items and other similar items. Attached Figure Description

[0051] With the cooperation of the fixing frame 410, the positioning bolt 420 and the positioning pin 421, the sorter can be quickly and securely installed on or removed from the forklift forks, simplifying the installation process, requiring no complicated tools, saving time, and allowing the equipment to be flexibly switched between different forklifts.

[0052] Please continue reading. Figure 1 The connecting frame 130 is equipped with an oil circuit control component 500. The oil circuit control component 500 includes a solenoid valve 510 connected to the main oil supply line via a connecting bolt, and a synchronization valve 511 connected to the outlet end of the solenoid valve 510. There are two sets of synchronization valves 511. The two sets of synchronization valves 511 are respectively connected to the X-axis clamping component 200 and the Y-axis clamping component 300. The oil circuit control component 500 also includes a pressure regulating valve 520 connected to the oil supply line, and a pressure gauge 521 connected to the pressure regulating valve 521.

[0053] The synchronization valve 511 in the oil circuit control component ensures that the two hydraulic cylinders driving the same set of clamping arms (such as two X-axis clamping arms) can extend and retract synchronously, so that the two sets of opposite clamping arms can contact the side of the goods in parallel, avoiding the goods being squeezed, deformed or damaged due to one side being subjected to force first. This is especially important for transporting goods packaged in cartons, fragile items and other similar packaging.

[0054] The hydraulic circuit control component 500, which integrates the solenoid valve 510, the synchronization valve 511, the pressure regulating valve 520 and the pressure gauge 521 on the connecting frame 130, realizes centralized management of the hydraulic system. The system working pressure can be easily set through the pressure regulating valve (monitored in real time by the pressure gauge), thereby adjusting the clamping force according to the weight and material of the goods. It realizes stepless switching between gentle mode and strong mode, which protects the goods and avoids system overload.

[0055] Working principle: When in use, this utility model forms a grid-shaped clamping frame by setting mutually perpendicular X-axis clamping components 200 and Y-axis clamping components 300. It can apply clamping force from four directions (front, back, left, and right) to the goods simultaneously, ensuring that the goods (especially pallets) are subjected to multi-dimensional constraints during forklift handling and movement. This effectively prevents the goods from swaying back and forth or shifting left and right, greatly improving the stability and safety of the handling process. Furthermore, through the synchronization valve 511 in the hydraulic control component, it is ensured that the two hydraulic cylinders driving the same set of clamping arms can extend and retract synchronously, so that the two sets of opposite clamping arms can contact the sides of the goods in parallel, avoiding the squeezing, deformation, or damage of the goods caused by one side being subjected to force first. This is especially important for transporting packaged goods such as cartons and fragile items.

[0056] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
