Description

Technical Field

[0001] The present invention relates to the technical field of awning recycling, and specifically to a drop-down awning folding and recycling device and a recycling method. Background Art

[0002] Rain cloth is mostly made of polypropylene or polyethylene materials, and is widely used in covering vehicles, ships, factory and mine goods, outdoor tourism and other fields. It mainly plays the role of covering objects and has the characteristics of sun resistance, anti-freeze, anti-aging, anti-corrosion, light weight and easy to fold.

[0003] The commonly used width specifications of tarpaulins are 12-16 meters, and the length is generally 16-30 meters. Due to their large size and heavy weight, the recycling and folding of tarpaulins are mostly done manually. The folding process requires the cooperation of two people. In a certain open space, the tarpaulin is first unfolded and flattened, and then folded layer by layer, and finally rolled into a cylindrical shape about 1.8 meters long.

[0004] During the implementation of the above method, the tarpaulin will inevitably be dragged and rubbed on the ground. Long-term dragging and friction will inevitably greatly reduce the service life of the tarpaulin. In addition, the folding and rolling of the tarpaulin using the above method is very cumbersome and requires a large number of people. Even a small number of people can take a long time to operate.

[0017] Based on the above-mentioned tarpaulin folding and recycling device, the present application proposes a drop-down tarpaulin folding and recycling method, which is implemented by the following steps:

[0018] S1. Multiple telescopic mechanisms are provided on either side of a predetermined vertical drop area of ​​the awning, serving as the awning folding area. The telescopic mechanisms all extend toward the awning, and the vertical planes along which the telescopic mechanisms extend are parallel to each other. The telescopic mechanisms on both sides are staggered. Driven by a driving force, the telescopic mechanisms on both sides extend toward the awning, and the front end of each group of telescopic mechanisms pushes the corresponding awning area forward, causing it to deform concavely, giving the awning a wavy structure as a whole.

[0019] S2. A tarpaulin rolling fork is set below the tarpaulin folding area as the tarpaulin rolling area. The rolling fork is driven to rotate by a driving mechanism. After the lower end of the tarpaulin folded in the tarpaulin folding area is compressed, the compressed tarpaulin is picked up by the rolling fork. The driving mechanism drives the rolling fork to rotate, thereby driving the folded and compressed tarpaulin to rotate, thereby realizing the rolling of the tarpaulin.

[0020] On the basis of the above steps, a tarpaulin compression area is further provided between the tarpaulin folding area and the tarpaulin rolling area for continuously compressing the tarpaulin. The tarpaulin compression area includes a tarpaulin compression mechanism provided below the telescopic mechanism. The tarpaulin that has been folded and moved downward in the tarpaulin folding area is continuously compressed from both sides to the center. The compression direction is horizontal and perpendicular to the telescopic direction of the telescopic mechanism. After continuous compression, the tarpaulin rotates with the winding fork to realize the winding of the tarpaulin.

[0021] As a preferred embodiment of the above method, in step S1, the two sides of the vertical falling area of ​​the awning are respectively folding area one and folding area two, the number of telescopic mechanisms in folding area one is one more than the number of telescopic mechanisms in folding area two, and the telescopic mechanisms in folding area two correspond one to one with the center of the interval area between the two adjacent groups of telescopic mechanisms in folding area one. When the awning is folded, the acute angles formed by the elongation directions of the telescopic mechanisms in folding area one and folding area two and the horizontal direction gradually decrease from the telescopic mechanism in the middle to the telescopic mechanisms on both sides.

[0022] As a preferred embodiment of the above method, in step S1, a freely rotatable push-type guide head is provided on one end of the telescopic mechanism for pushing the tarpaulin to be folded, and the axial direction of the push-type guide head is horizontal and perpendicular to the telescopic direction of the telescopic mechanism.

[0023] As a preferred embodiment of the above method, in step S2, a group of winding forks are arranged on each side of the tarpaulin, which are driven to rotate by a group of driving mechanisms respectively. The two groups of winding forks are arranged facing each other, and each group of driving mechanisms is provided with a telescopic assembly, which can drive the driving mechanism and the winding fork to move forward and backward along the forking direction of the winding fork to fork the compressed tarpaulin and release the rolled-up tarpaulin.

[0024] As a preferred embodiment of the above method, the tarpaulin compression step is as follows: two parallel compression plates constituting the tarpaulin compression mechanism are driven by a telescopic assembly connected thereto to move toward each other to compress the tarpaulin between the two compression plates; one or more guide rollers are respectively provided on opposite sides of the two compression plates, and the axial direction of the guide rollers is horizontal and perpendicular to the compression direction of the compression plates.

[0025] The beneficial effects of the above scheme are:

[0026] 1. In the above technical solution, the tarpaulin is folded and rolled up by releasing it longitudinally from top to bottom and making it enter the folding area, compression area and rolling area in sequence. Compared with the traditional tarpaulin collection method (laying the tarpaulin flat on the ground for folding, pulling and rolling), the wear of the tarpaulin is avoided to a great extent, and the service life of the tarpaulin is effectively improved.

[0027] 2. In the above technical solution, a rotatable guide head is provided at the front end of the telescopic mechanism. The guide head is in direct contact with the tarpaulin. When the tarpaulin falls, the guide head can realize passive rotation under the action of friction, which can not only guide the falling process of the tarpaulin, but also reduce the friction between the tarpaulin and the guide head, thereby further reducing the wear on the tarpaulin and effectively improving the service life of the tarpaulin.

[0028] 3. The telescopic mechanism in the folding area can adjust the pitch angle under the action of the second electric push rod, so that the telescopic mechanism in the middle position can first push the tarpaulin to produce concave deformation, and the telescopic mechanisms on both sides can push the tarpaulin to produce concave deformation later, avoiding the problem that the two sides of the tarpaulin complete the concave deformation first, resulting in the central area of ​​the tarpaulin being unable to undergo concave deformation. This method of gradual concave deformation from the middle area to both sides can make the tarpaulin better folded to form a wavy structure, effectively ensuring the folding effect of the tarpaulin.

[0029] 4. The setting of the tarpaulin compression mechanism in the compression area plays a good transition role for the tarpaulin from the folding area to the rolling area. It squeezes and compresses the folded tarpaulin to effectively reduce the thickness of the tarpaulin after being folded, which provides convenience for the tarpaulin to be picked up by the rolling fork in the subsequent steps. Only simple manual processing is required to make the rolling fork accurately pick up the tarpaulin in the folded state, effectively reducing tedious manual operations.

[0030] 5. The above technical solution solves the problem that the existing technology cannot achieve mechanized rolling of the tarpaulin, effectively reduces labor costs and greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The roller's axis is horizontal and perpendicular to the length of the telescopic plate 22.

[0050] In this embodiment, the number of telescopic mechanisms of the guide component 1 2a is one more than the number of telescopic mechanisms of the guide component 2 2b.

[0054] The following describes an embodiment of the drop-down awning folding and recycling method in combination with the working principle of the above-mentioned device.

[0055] Folding tarpaulin

[0056] Taking the tarpaulin used on a large truck as an example, when the tarpaulin needs to be rolled up, the above device is placed just below the tarpaulin, and the tarpaulin is controlled to gradually fall from the top and enter the tarpaulin folding area A. Figure 1 As shown, a set of push-type folding guide assemblies is installed on both sides of the awning folding area. Each set includes multiple telescopic mechanisms. Each telescopic mechanism has a freely rotatable push-type guide head at the front end, with its axis horizontal and perpendicular to the telescopic mechanism's extension direction. The telescopic mechanisms all extend toward the awning, and the vertical planes along which the telescopic directions of all the telescopic mechanisms extend are parallel to each other. The telescopic mechanisms on both sides are staggered. When the telescopic mechanisms extend toward the awning under the action of driving force, the front end of each set of telescopic mechanisms pushes the corresponding area of ​​the awning forward, causing it to deform concavely, giving the awning an overall wavy structure.

[0057] The folding step is completed when the tarpaulin forms a wavy structure.

[0058] Rain cover compression

[0059] A tarpaulin compression area C is provided below the tarpaulin folding area. Figure 1As shown, it is used to continuously compress the tarpaulin, which includes a tarpaulin compression mechanism arranged below the telescopic mechanism, and utilizes the telescopic assembly to push the two compression plates to move toward each other along the horizontal guide rod, thereby continuously compressing the tarpaulin that has been folded and moved downward between the two compression plates from both sides to the center, and its compression direction is horizontal and perpendicular to the telescopic direction of the telescopic mechanism.

[0060] The first guide roller and the second guide roller arranged on the sides of the two compression plates guide and squeeze the tarpaulin. The distance between the two upper first guide rollers is greater than the distance between the two lower second guide rollers, so that when the tarpaulin is folded and passes through the compression mechanism, the channel in the compression area of ​​the tarpaulin forms a V-shaped structure, so that the tarpaulin can pass through the area more smoothly and the compression effect is better.

[0061] Roll up tarpaulin

[0062] Two sets of opposite tarpaulin rewinding forks are arranged below the tarpaulin compression area as the tarpaulin rewinding area B. Figure 1 As shown, the winding fork is driven to rotate by the driving mechanism. After the lower end of the awning folded in the awning folding area is compressed, the compressed awning is picked up by the winding fork. The driving mechanism drives the winding fork to rotate, thereby driving the folded and compressed awning to rotate, thereby realizing the winding of the awning.

[0063] Since the driving mechanism is equipped with a telescopic assembly, it can drive the driving mechanism and the winding fork to move forward and backward along the forking direction of the winding fork. Therefore, when the winding fork completes the winding of the tarpaulin, the telescopic assemblies on both sides retract backward, and the winding fork can be pulled out from the rolled tarpaulin to release the rolled tarpaulin.

[0064] In order to ensure the folding effect of the tarpaulin, in the above steps, the two sides of the vertical falling area of ​​the tarpaulin are set as folding area one and folding area two respectively. The number of telescopic mechanisms in folding area one is 5, and the number of telescopic mechanisms in folding area two is 4. The telescopic mechanisms in folding area two correspond one to one with the center of the spacing area between the two adjacent groups of telescopic mechanisms in folding area one.

[0065] When folding the tarpaulin, the acute angles formed by the extension directions of the telescopic mechanisms in folding area 1 and folding area 2 and the horizontal direction gradually decrease from the telescopic mechanism in the middle to the telescopic mechanisms on both sides, that is, the lines connecting the centers of the push-type guide heads in each folding area form an arched structure opening downward, so as to ensure that the push-type guide head at the front end of the telescopic mechanism in the middle position contacts the tarpaulin earlier than the other push-type guide heads on both sides of the same side, and pushes forward to make the area of ​​the tarpaulin form a depression earlier.

[0066] Multiple experiments have shown that the method of extending all telescopic mechanisms forward at the same time to push the tarpaulin in the corresponding area to cause a concave deformation cannot achieve a good folding effect due to the large size and weight of the tarpaulin and its poor flexibility.

[0067] By using the push-type guide head in the middle position to first push the middle part of the tarpaulin to cause a concave deformation, and then using the push-type guide heads on both sides to gradually spread the concave deformation of the tarpaulin to both sides, the tarpaulin can be gradually contracted from both sides to the middle, thereby effectively ensuring a good folding effect of the tarpaulin.

[0068] Finally, some of the problems in the above technical solution are explained as follows:

[0069] 1. The "push-type" mentioned above means that the push-type guide head can extend forward and push the tarpaulin in the corresponding area to cause a concave deformation under the push of the telescopic mechanism at its rear.

[0070] 2. The push-type guide head adopts a roller connected to the front end of the telescopic plate of the telescopic mechanism through a bearing, which can rotate freely. It can effectively ensure that the roller passively rotates under the action of the friction force when the tarpaulin falls, so as to guide and buffer the tarpaulin.

[0071] 3. In the above scheme, the telescopic components mentioned in the tarpaulin compression mechanism and the tarpaulin rewinding mechanism can adopt the multi-link mechanism and driving mechanism in the prior art to realize the telescopic function (such as Figure 7 and 8 As shown), or directly adopt electric push rod, hydraulic cylinder or pneumatic cylinder and other structures to realize the telescopic function.

[0072] 4. Before folding the tarp, a lifting device can be used to lift the tarp so that it is directly above the folding area. In this embodiment, the technical solution of the automatic tarp retracting device described in Patent 201821691388.4 can be adopted. The automatic retracting device is lifted by a forklift, and the tarp is pre-wound on the retracting roller. By controlling the rotation of the retracting roller, the tarp can be controlled to fall into the folding area.

[0073] 5. It should be noted that, in the above structure, the push-type guide head can also include a drive motor 29, which is installed at the front end of the telescopic plate. The output shaft of the drive motor 29 is coaxially connected to the roller. The motor drives the roller to actively rotate, which can effectively ensure the smoothness of the tarpaulin falling. Figure 11 shown.

[0074] 6. In addition, multiple rubber strips 241 can be evenly arranged on the outer circumference of the roller to form an arc structure. The outer arc surface of the rubber strips 241 contacts the tarpaulin and plays a pulling role in the fall of the tarpaulin without causing damage to the tarpaulin. Figure 11 shown.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
