Description

Technical Field

[0001] This field relates to the technology of tarpaulin recycling, specifically a self-service tarpaulin folding and recycling machine. Background Technology

[0002] Rain tarpaulins are mostly made of polypropylene or polyethylene and are widely used for covering vehicles, ships, factory and mining goods, and outdoor tourism. They mainly serve to cover items and have the characteristics of sun protection, frost resistance, aging resistance, corrosion resistance, lightweight and easy folding.

[0003] The tarpaulins used in general are large in size and heavy in weight. Currently, the recycling and folding of tarpaulins is mostly done manually.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the specific embodiments described are only some embodiments of the present invention, and not all embodiments.

[0036] like Figure 1 , 2 As shown in Figure 3, a self-service tarpaulin folding and recycling machine is provided. One side of the cabinet 1 is provided with a tarpaulin inlet 100, and the other side of the cabinet is provided with a tarpaulin roll outlet 101. Preferably, a cabinet door 1010 is slidably connected to the side wall of the cabinet on the side of the tarpaulin roll outlet 101. The side of the cabinet door 1010 is connected to the telescopic rod of the electric push rod 1011. The base of the electric push rod 1011 is fixedly connected to the side wall of the cabinet 1.

[0037] A folding guide mechanism 2 is provided in the cabinet near the tarpaulin inlet 100, and a winding mechanism 6 is provided in the cabinet near the tarpaulin roll outlet 101. The folding guide mechanism 2 includes multiple vertically and parallelly arranged tarpaulin dividers 203. The lower end of the tarpaulin dividers 203 is connected to the cabinet 1 through a lifting mechanism 21, so that the divider base 201 can move vertically relative to the cabinet 1. A pressing forming component 20 is provided directly above the area between two adjacent tarpaulin dividers 203. The lower part of the pressing forming component 20 extends downward into the area between the two adjacent tarpaulin dividers 203, pressing the tarpaulin 5 in this area to form a wavy structure.

[0038] Preferably, the tarpaulin folding guide mechanism 2 further includes multiple rows of vertically and parallelly arranged guide frames 208, the arrangement direction of which is perpendicular to the conveying direction of the tarpaulin 5 (as shown in the attached figure). Figure 2As shown, the conveying direction of the tarpaulin is from right to left. The guide frame 208 is generally located at the tarpaulin inlet 100. Preferably, the guide frame 208 is respectively set at both ends of the tarpaulin separator 203 to guide the tarpaulin during conveying, so as to facilitate the smooth entry of the tarpaulin into the winding mechanism 6.

[0039] Depend on Figure 4 Furthermore, the lifting mechanism 21 includes a guide seat 202 and an electric push rod 207. The guide seat 202 is located at the bottom of the cabinet 1, and the guide seat 202 is slidably connected to one side of the lower end of the rain cover divider 203. Specifically, as shown... Figure 6 As shown, a guide groove 2020 is vertically opened on one side of the guide seat 202. A guide wheel 211 is provided on the side of the tarpaulin divider 203 opposite to the guide groove. The guide wheel cooperates with the guide groove and can roll along the guide groove 2020. The base of the electric push rod 207 is connected to the bottom of the cabinet 1. The end of the telescopic rod of the electric push rod 207 is connected to the lower end of the tarpaulin divider 203. The telescopic rod of the electric push rod 207 extends and retracts in the vertical direction to raise and lower the tarpaulin divider 203.

[0040] Preferably, each row of rain cover dividers 203 includes a front rain cover divider 2031 and a rear rain cover divider 2032. The bottom ends of the front rain cover divider 2031 and the rear rain cover divider 2032 are connected by several connecting base frames 201, and the telescopic rod end of the electric push rod 207 is connected to the lower end of the connecting base frame 201.

[0041] The top of the tarpaulin divider 203 is provided with a rotating component 204. The rotating component can be one or more of rotating parts such as rollers, wheels, rollers, or bearings. The rotation axis of the rotating component 204 is set parallel to the conveying direction of the tarpaulin. When the tarpaulin is pressed and folded by the pressing and forming assembly, the tarpaulin can drive the rotating component to rotate under the action of friction, which helps to reduce the movement resistance of the tarpaulin.

[0042] The multiple rows of tarpaulin dividers 203 are evenly arranged in the horizontal direction, and their bottom ends are connected by a connecting base 201 to form a whole. Through the longitudinal extension and retraction of two electric push rods, all the tarpaulin dividers 203 can be raised and lowered in the vertical direction.

[0043] Depend on Figure 5Furthermore, the guide frame 208 is supported by two columns to form an inverted V-shaped structure. The upper ends of the two columns are fixedly connected, and the lower ends are fixed to the cabinet 1. The top of the two columns is provided with a rotating component 210. The rotating component can be one or more of the rotating parts such as rollers, wheels, or bearings. The axial direction of the rotating component 210 is horizontal and perpendicular to the conveying direction of the tarpaulin. When the electric push rod 207 pushes the partition frame base 201 to rise to the highest point, the highest point of the rotating component 204 at the top of the tarpaulin partition frame 203 is higher than the highest point of the rotating component 210. When the electric push rod drives the partition frame base 201 to fall to the lowest point, the highest point of the rotating component 204 is lower than the highest point of the rotating component 210.

[0044] Preferably, the side of the column is further provided with a side rotating component 209. The side rotating component can be one or more of rotating parts such as rollers, wheels, rollers or bearings. The side rotating component 209 can be sleeved on the guide frame. The central axes of the two side rotating components 209 on the same guide frame are coplanar, and the plane is perpendicular to the conveying direction of the rain cloth. The two side rotating components 209 are arranged in a figure-eight shape and symmetrically distributed on both sides of the corresponding rain cloth separator frame 203.

[0045] Depend on Figure 2 , 3 Further, as can be seen from points 9 and 10, in order to effectively improve the effect and efficiency of subsequent rain cloth winding, a pair of pressing rollers 3 are provided between the rain cloth folding guide mechanism 2 and the winding mechanism 6. Before the rain cloth is clamped and wound by the telescopic rod 601, the pair of pressing rollers 3 press and guide the folded rain cloth 5. The axis of the pressing rollers 3 is set in the vertical direction, and the two pressing rollers 3 are axially symmetrically distributed with respect to the rotation center axis of the telescopic rod 601. To allow the pressing roller 3 to move perpendicular to the conveying direction of the tarpaulin 5, a clamping window 103 is provided on the top of the cabinet corresponding to the pressing roller. A clamping slide rail 305 is provided at the edge of the clamping window, and the clamping slide rail 305 is perpendicular to the conveying direction of the tarpaulin 5. A roller slide 302 is slidably mounted on the clamping slide rail 305. The rotating shaft of the pressing roller 3 passes through the clamping window 103 and is rotatably mounted on the roller slide 302. The side of the roller slide 302 is connected to the reciprocating telescopic mechanism 303. The purpose of using the pressing roller 3 is to expel the air inside the folded tarpaulin in advance, which is beneficial to the subsequent winding effect of the tarpaulin.

[0046] In addition, it is best to also rotate the other shaft of the pressing roller 3 onto the second roller slide 3020 located at the bottom of the cabinet 1. The bottom of the cabinet corresponding to the pressing roller 3 is provided with a second clamping slide rail 3050, and the second clamping slide rail is perpendicular to the conveying direction of the tarpaulin 5. The second roller slide 3020 is slidably mounted on the second clamping slide rail 3050, and the side of the second roller slide 3020 is connected to the telescopic component of the reciprocating telescopic mechanism 303.

[0047] The pressing roller 3 can be either a passive, follow-up mode where it rotates with the tarpaulin, or a powered, active rotation mode. For better quality, the active rotation mode is preferred. There are many active rotation modes, such as one end of the pressing roller 3 being rotatably mounted on a roller slide 302, with a roller motor 301 fixed to the top of the slide 302. The drive shaft of the roller motor 301 is connected to the end of the pressing roller 3's rotating shaft via a spline or coupling, allowing the roller motor 301 to directly drive the pressing roller 3.

[0048] It should be noted that the clamping window 103 is not a necessary component of this invention; its function is to facilitate the installation of the reciprocating telescopic mechanism 303 on the top of the cabinet and to facilitate the installation of the roller motor 301. In follow-up mode, the roller slide 302 and the reciprocating telescopic mechanism 303 can be directly suspended and installed on the top of the cabinet. Even in active rotation mode, the roller motor 301 can be installed inside the clamping roller 3 (such a structure exists in the prior art, such as a hub motor), and the roller slide 302 and the reciprocating telescopic mechanism 303 can be suspended and installed on the top of the cabinet.

[0049] One possible structure for the reciprocating telescopic mechanism 303 is as follows: the mechanism includes an electric push rod 3030, a connecting rod 306, and a mounting plate 3031 located on the outer side of the top of the cabinet. The mounting plate 3031 is hinged to the base of the electric push rod 3030. The telescopic rod end of the electric push rod 3030 is hinged to the power arm of the first connecting rod 3062. The support shaft of the first connecting rod 3062 is located on the mounting plate 3031 on the outer side of the top of the cabinet. The resistance arm of the first connecting rod is hinged to one end of the second connecting rod 3063, and the other end of the second connecting rod 3063 is hinged to the side of the roller slide 302.

[0050] Of course, the reciprocating telescopic mechanism 303 can also use pneumatic push rods, linear motors, electric push rods, and other parts that can extend and retract axially.

[0051] To improve the folding effect of the tarpaulin, such as Figure 3 As shown, the pressing and forming assembly includes a pressing frame 205 and an electric push rod 206. The pressing frame 205 is a flat square frame structure. All pressing frames 205 are arranged in parallel. The upper frame of the pressing frame 205 is hinged to the cabinet 1 on the side near the winding mechanism 6. The electric push rod 206 is located above the pressing frame 205. The base of the electric push rod 206 is hinged to the cabinet 1 directly above the pressing frame 205. The telescopic rod of the electric push rod 206 is hinged to the middle of the upper frame of the pressing frame 205. The end of the lower frame of the pressing frame 205 is rounded. Driven by the electric push rod 206, the pressing frame 205 can perform pitching motion around the hinge part between the pressing frame 205 and the cabinet 1 in the interval area between the corresponding two sets of rain cloth separators 203 to complete the folding of the rain cloth.

[0052] Depend on Figure 7 , 8 Furthermore, the winding mechanism 6 includes a winding slide rail 609, a winding reel table 605, and a reciprocating mechanism 603. The top of the cabinet corresponding to the winding reel table is provided with a winding window 102. A winding slide rail 609 is provided at the edge of the winding window 102, and the winding slide rail 609 is perpendicular to the conveying direction of the tarpaulin 5. The winding reel table 605 is slidably mounted on the winding slide rail 609. Specifically, a winding slide rail 609 can be provided on each side of the winding window 102. A slider 6090 is slidably mounted on the winding slide rail 609, and the top of the slider 6090 is fixedly connected to the bottom of the winding reel table 605.

[0053] A winding motor 6053 is provided on the side of the winding reel table 605. A winding bevel gear 6050 is rotatably mounted at the center of the winding reel table 605. The winding bevel gear 6050 has two mounting holes 6051 symmetrically inserted through its axis. An electric push rod 607 is fixedly installed at the entrance of the mounting hole 6051 (the upper end face of the winding bevel gear 6050). The telescopic rod 601 of the electric push rod 607 passes through the mounting hole 6051 and can extend into the cabinet. The tooth surface of the winding bevel gear 6050 meshes with the tooth surface of the drive bevel gear 6052. The drive bevel gear 6052 is fixed on the power output shaft of the winding motor 6053. A corresponding light-shielding photoelectric switch P1 is provided at the bottom end of the telescopic rod 601 of the two electric push rods 607 (one of which is equipped with a laser emitter, and the other is equipped with a photoelectric element corresponding to the laser emitter).

[0054] The 6053 winding motor can be controlled by a servo motor. The approximate diameter of the tarpaulin can be determined by the number of rotations fed back by the servo motor, and this information is then sent to an external display terminal for the user to know.

[0055] The winding reel platform 605 is connected to the reciprocating mechanism 603. One possible structure for the reciprocating mechanism 603 is as follows: the mechanism includes a lead screw 6030 located on one side of the winding slide rail 609 and a threaded sleeve 6031 located at the bottom of the winding reel platform 605. The lead screw 6030 and the threaded sleeve 6031 are screwed together. The outer end of the lead screw is connected to the power output shaft of the winding drive motor 608 fixed to the outer side of the top of the cabinet. During implementation, the diameter of the winding bevel gear 6050 should be larger than the diameter of the drive bevel gear 6052 to achieve speed reduction. Furthermore, to avoid affecting the operation of the telescopic rod 607, the threaded sleeve 6031 needs to make way for the telescopic rod 607 and is eccentrically located at the bottom of the winding reel platform 605, specifically on the side of the telescopic rod 607 at the bottom of the winding reel platform 605.

[0056] The reciprocating mechanism 603 described above can also adopt existing reciprocating chain, belt and other structural designs.

[0057] The telescopic rods 601 of the two electric push rods 607 mentioned above can be lowered to achieve the winding of the rain cloth. The detection process is as follows: when the telescopic rod 601 is lowered a certain distance, if the photoelectric switch P1 at its bottom is blocked by the rain cloth, the output electrical signal is a low level signal. Therefore, it is considered that the rain cloth 5 is sandwiched in the middle, and the winding motor 6053 starts to work.

[0058] Otherwise, the telescopic rod 601 returns to its original position, and the reciprocating mechanism 603 finely adjusts the position of the take-up reel 605 to the left or right (the fine adjustment can be set to 3-6 cm). Then it descends until the photoelectric switch P1 is blocked by the tarpaulin, thus determining the accurate position of the tarpaulin. Since the middle position of the pressure roller 3 is on the same line as the middle position of the two telescopic rods 601, the tarpaulin will enter the middle position of the two telescopic rods 601 after exiting the pressure roller 3. Under normal circumstances, no adjustment is required, but setting a fine-tuning program can increase the safety factor.

[0059] Depend on Figure 2 Furthermore, the winding mechanism 6 also includes a rain cloth roll storage slide 60, which is located at the bottom of the cabinet opposite the telescopic rod of the electric push rod 607. The slide 60 is preferably inclined, with the lower end of the slide located on the side of the rain cloth roll output port. The rain cloth roll storage slide is provided with multiple sliding rollers 6001 to better facilitate the sliding of the rain cloth roll 50. Baffles 6002 are provided on both sides above the slide to prevent the rain cloth roll from tipping over.

[0060] The telescopic rod 601 of the electric push rod is used as a rain cloth rewinding fork. After the telescopic rod 601 extends into the cabinet body near the bottom, it is driven by the winding motor 6053 to rotate around the vertical axis. The two telescopic rods 601 are used to clamp the folded rain cloth, and the rotation of the two telescopic rods 601 is used to rewind the rain cloth.

[0061] Depend on Figure 1 It is known that the outer side of the cabinet of the rain cloth inlet 100 is provided with multiple parallel roller support frames 103. The gap between the roller support frames 103 can ensure that the pressure frame 205 can pass through. The roller support frame is provided with rollers 1030 parallel to the rain cloth inlet.

[0062] Alternatively, it can also be done by Figure 11 It is known that the outer side of the cabinet of the rain cloth inlet 100 is provided with multiple parallel cloth support rods 103, and the gap between the cloth support rods 103 can ensure that the pressure frame 205 can pass through.

[0063] To improve work efficiency, the automatic tarpaulin folding machine control system of this invention is mainly composed of: equipment control system, sensors, cameras, industrial routers, self-service display terminals, etc.

[0064] The sensor includes several photoelectric switches P1 ( Figure 8 As shown), P3 ( Figure 3 (as shown in the image). During the rolling process, photoelectric switch P3 can automatically calculate the length of the rolled tarpaulin, with accurate data, eliminating the need for manual measurement.

[0065] The equipment control system can use an industrial computer (2G DDR2 / 320GHD / 6 serial ports / 1 parallel port / 4 USB / sound card / 100Mbps network card), or it can use a microcontroller control circuit based on a microcontroller such as C51 or STM32F103R8T6.

[0066] The equipment control system can interconnect with a cloud server or host computer via an industrial router. External sensors and cameras collect equipment data in real time. The self-service display terminal uses a touchscreen (P0) to input commands and display system status, allowing users to scan codes to retrieve items. The main control system is responsible for all sensor data acquisition, action command sending, logic judgment, and fault handling. The system issues corresponding judgments and commands based on different product models, thereby driving various servo motors to work and achieving intelligent control. Simultaneously, it can store the data of the rain tarpaulin rolls on a cloud server via the industrial router for easy subsequent querying and tracking. All the above circuitry is existing technology in existing self-service machines; therefore, this invention can be freely implemented.

[0067] When returning the tarpaulin, the user places the front of the tarpaulin 5 on the roller support or the tarpaulin support rod 103 and pushes the tarpaulin 5. The tarpaulin 5 enters through the tarpaulin inlet 100 and moves through the guide frame 208 and the front tarpaulin divider 2031 to directly above the rear tarpaulin divider 2032. At the same time, the pressing frame 205 above the tarpaulin rotates around the hinge under the drive of the electric push rod, causing the front end of the pressing frame 205 to move downward to the gap area between the adjacent tarpaulin dividers 203 below. During the downward movement, the lower edge of the pressing frame 205 will contact the tarpaulin below and exert downward pressure on the tarpaulin, causing the tarpaulin in the gap area to be pressed down into the gap area by the pressing frame 205, thereby forming a wave-shaped structure in that section of the tarpaulin, thus completing the folding process of that section of the tarpaulin. During the above process, the rotating component 204 at the upper end of the tarpaulin divider 203 rotates with the tarpaulin under the action of friction. Its main function is to guide the tarpaulin and ensure the smooth movement of the tarpaulin 5 during folding. It should be noted that during the above process, all the pressing frames 205 do not press down synchronously, but have a certain time delay. The time for the pressing frames 205 to press down on the tarpaulin gradually delays from the middle pressing frame 205 to the pressing frames 205 on both sides. That is, among all the pressing frames 205, one or two pressing frames 205 in the very middle area press down on the tarpaulin first, causing the tarpaulin to enter the corresponding interval area and form a protrusion. Then, the pressing frames 205 on both sides of the one or two pressing frames 205 press down on the tarpaulin, causing the tarpaulin to enter the corresponding interval area and form a protrusion, until the pressing frame 205 at the very edge completes the pressing action.

[0068] After folding, the electric push rod at the bottom of the tarpaulin divider 203 drives the tarpaulin divider 203 to move down, while the pressure frame 205 moves up (whether the pressure frame 205 needs to be raised to its original position here), so that the tarpaulin 5 is supported by the front and rear guide frames 208. The tarpaulin 5 then enters the range of the two pressing rollers 3. The two pressing rollers 3 move back to the center and rotate in opposite directions, venting and clamping the folded tarpaulin 5 and limiting it to the middle position of the cabinet, and sending the folded tarpaulin directly below the electric push rod 607.

[0069] Once one end of the tarpaulin is clamped into place by the telescopic rod 601, it is wound up under the drive of the winding motor 6053. The speed of the winding motor 6053 is adjustable, and the rotation of the telescopic rod 601 provides a certain stretching force for the entire tarpaulin to move forward. Driven by the rotational force of the telescopic rod 601, the tarpaulin is gradually stretched and straightened backward, while the front tarpaulin continuously enters above the tarpaulin separator 203. When the photoelectric switch P3 (located below the feed inlet of the pressing roller 3)... Figure 3 (As shown) When no tarpaulin signal is detected, it means that the tarpaulin is finished rolling, and the winding motor 6053 decelerates and stops.

[0070] After the roll is finished, the telescopic rod 601 of the electric push rod 607, driven by the reciprocating telescopic mechanism, moves the tarpaulin roll along the tarpaulin roll storage slide to a position close to the tarpaulin roll output port. Then, the telescopic rod of the electric push rod rises and disengages from the tarpaulin roll, allowing the tarpaulin roll to be stored in this section. The above steps are repeated to complete the folding and rolling process of the tarpaulin in the next adjacent section, ultimately forming a row of folded tarpaulin rolls in the tarpaulin roll storage slide.

[0071] Once the equipment is ready, simply set the parameters for the product to be folded on the monitor. The built-in program will automatically control the servo motors to fold, clamp, and roll up the tarpaulin. Simultaneously, the system monitors the equipment's operating status in real time, including all sensors and servo motors. The camera initiates visual inspection and sends the feedback data to the display screen in real time. Once rolled up, the system automatically generates information including the number of folds and whether the tarpaulin is intact, along with a QR code and a photo of the tarpaulin, facilitating subsequent tracking, retrieval, and scanning for product retrieval.

[0072] The user can control the extension and retraction of the telescopic rod of the electric push rod 1011 through the terminal P0 to open the cabinet door 1010. Then, driven by the reciprocating extension mechanism, the extension rod 601 of the electric push rod 607 moves the folded tarpaulin roll queue towards the cabinet door 1010. When a folded tarpaulin roll is pushed out and the cabinet door is closed immediately, the user can take it.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
