Description

Technical Field

[0001] The invention relates to the technical field of plastic hoarding processing, and in particular to a plastic hoarding feeding device and a feeding method. Background Art

[0002] Plastic panels, also known as plastic panel boxes, are a foldable or stackable plastic box structure composed of a pallet, a box body, a box cover and other parts. The preparation process of plastic panels mainly involves preparing a long section of material through loading, feeding, heating, bending and unloading. Due to the long length of plastic panels, a large amount of physical space is required for storage before processing. Generally, processing plants have sufficient height space. Therefore, stacking plastic panels into a U shape can effectively reduce the floor area occupied and make full use of the height space.

[0003] Currently, plastic hoardings are mostly placed flat on a plane and moved in the X, Y, and Z directions by moving mechanisms such as slide rails. However, there is little discussion on stacking the plastic hoardings in a U shape to save area and loading the U-shaped plastic hoardings. Summary of the invention

[0004] The present invention provides a plastic panel loading device and a loading method, the purpose of which is to solve the problems existing in the prior art.

[0005] The present invention proposes a plastic panel feeding equipment, comprising: a transplanting mechanism and a suction cup driving mechanism, the transplanting mechanism comprising a moving component with two degrees of freedom of movement in X and Z directions, the suction cup driving mechanism comprising a third transverse slide rail and a feeding suction cup component, the moving component with the degree of freedom of movement in the Z direction is slidably connected to the third transverse slide rail through a second slider, the third transverse slide rail is connected to two feeding suction cup components with opposite movement directions and capable of rotating 90 degrees through a slider, the feeding suction cup component comprises a mounting frame, a rotating motor, a suction cup, a rotating frame, and a telescopic component, the mounting frame is mounted with a rotating motor, the output end of the rotating motor is fixedly connected with a rotating frame, two telescopic components are mounted on the rotating frame, a suction cup is fixedly mounted on one end of the telescopic component away from the rotating motor, the suction cup is elliptical in shape, after the suction cup is flipped 90 degrees, the short axis of the suction cup is in the vertical direction, the area below the suction cup is made of a material with low hardness and easy to deform, and the remaining areas are made of a material with high hardness and not easy to deform.

[0006] Furthermore, the third transverse slide rail includes a laser ranging sensor A and left and right rotating screws with external threads in opposite directions at both ends of the outer ring surface, and the two opposite directions of the external threads of the left and right rotating screws are respectively connected to a left-hand slider and a right-hand slider engaged with the external threads, and the left-hand slider and the right-hand slider are respectively connected to a loading suction cup assembly and a laser ranging sensor B, and the laser ranging sensor A is arranged in the middle position of the third transverse slide rail.

[0007] Furthermore, the telescopic assembly includes two spring components, and the two spring components are symmetrically arranged on the edges of the suction cup. The line connecting the center points of the two spring components and the suction cup is in the same straight line as the short axis of the suction cup. When the telescopic assembly is parallel to the ground, the line connecting the center points of the two spring components and the suction cup is perpendicular to the ground.

[0008] Furthermore, the spring component includes a compression spring, a limit shell, an electric telescopic block, a compression component, and a tension and pressure sensor. The limit shell is fixedly mounted on the rotating frame. The limit shell is a hollow cylinder with a certain thickness. The tension and pressure sensor is fixedly mounted on the rotating frame inside the limit shell. The tension and pressure sensor is fixedly mounted with a compression spring at one end away from the rotating frame. The compression spring is fixedly mounted with a compression component at one end away from the tension and pressure sensor. The electric telescopic block is arranged inside the limit shell.

[0009] Furthermore, the compression component includes a compression rod, a movable ball, and a groove. The compression rod is connected to a compression spring. A plurality of movable balls are provided on the compression rod near the end of the compression spring. The movable balls are in rolling contact with the limit shell. The groove is provided on the compression rod. The groove is a smooth transverse funnel shape. The side with a large surface area is provided on the outer surface of the compression rod, and the side with a small surface area is provided inside the compression rod. The end of the groove is located inside the compression rod and is in an arc shape.

[0010] Furthermore, the electric telescopic card block is arc-shaped near the compression rod end, and a rubber head is provided at the insertion end of the electric telescopic card block. The central axis of the arc of the electric telescopic card block is consistent with the central axis of the arc of the groove. The width of the electric telescopic card block is not greater than the minimum width of the groove. The total length of the electric telescopic card block when it pops out is greater than the total length of the groove. The electric telescopic card block pops out when the compression spring is not subject to force.

[0011] A feeding method for a plastic panel feeding device comprises the following steps:

[0012] S1 positioning, first, the feeding suction cup assembly is moved toward each other to the middle position of the third transverse slide rail through the third transverse slide rail, and then, the suction cup drive mechanism is moved to the top of the U-shaped plastic enclosure through the moving assembly with the freedom of movement in the X and Z directions in the transplanting mechanism, and at the same time, it is ensured that after the feeding suction cup assembly is rotated 90 degrees, the height of the suction cup is lower than the side height of the U-shaped plastic enclosure stacked at the bottom, so as to ensure that it can be adsorbed to each plastic enclosure;

[0013] S2 adsorption, through the rotating motor, drives the rotating frame, telescopic assembly and suction cup to rotate 90 degrees towards the plastic panels on both sides, and starts the pulling pressure sensor, and through the third transverse slide rail, the loading suction cup assembly located in the middle position moves back to the two sides of the plastic panels and continues to move back to each other. When the suction cup contacts the plastic panels, the compression spring at the corresponding position of the suction cup is compressed after being subjected to pressure, and the loading suction cup assembly continues to move back to each other until all the compression springs are compressed by pressure. At this time, the suction cup is completely in contact with the plastic panels, and then the third transverse slide rail stops the loading suction cup from moving back to each other, and the suction cup adsorption is performed;

[0014] S3 unloading, after the suction cup absorbs the plastic enclosure, the loading suction cup assembly is moved toward each other through the third transverse slide rail, and the absorbed enclosure is moved upward through the transplanting mechanism. When the tension and pressure sensor measures that there is no force, the electric telescopic block pops up and uses the rebound force of the compression spring to insert into the groove. When the electric telescopic block is inserted into the groove, the third transverse slide rail stops the loading suction cup assembly from moving toward each other. When the plastic enclosure moves out of the storage device, the third transverse slide rail causes the loading suction cup assembly to move away from each other. At the same time, the rotating motor drives the rotating frame, the telescopic assembly and the suction cup to rotate 90 degrees to present a vertical state. When the rotating frame, the telescopic assembly and the suction cup rotate 90 degrees, the distance measured by the laser ranging sensor A is not less than the distance measured by the laser ranging sensor B. When the distances measured by the laser ranging sensor A and the laser ranging sensor B are the same, the opposite movement of the loading suction cup assembly is stopped, and then the plastic enclosure is unloaded by moving downward through the transplanting mechanism, and then the electric telescopic block is retracted to turn off the tension and pressure sensor.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The present application can conveniently adsorb the U-shaped plastic enclosure by rotating the feeding suction cup assembly 90 degrees. At the same time, through the two spring components symmetrically arranged up and down on the suction cup, the adaptive ability of the suction cup can be improved during compression adsorption, and it can be fully in contact with the plastic enclosure, thereby improving work efficiency;

[0017] 2. The present application designs the suction cup to be elliptical in shape. When the suction cup is flipped 90 degrees for adsorption, the short axis of the elliptical suction cup is in the vertical direction. When adsorbing, the plastic enclosures in the upper and lower directions of the suction cup have a certain angle slope. By adopting an elliptical suction cup with the short axis in the vertical direction, the angle difference can be effectively reduced, which is convenient for adsorption. Since the area below the suction cup contacts the U-shaped plastic enclosure first during adsorption, the area below the suction cup is made of a material with lower hardness and easy to deform, and the remaining area is made of a material with higher hardness and not easy to deform, which can effectively improve the adsorption capacity and reduce the damage to the U-shaped plastic enclosure during adsorption.

[0018] 3. In the present application, a plurality of movable balls are arranged near the compression spring end of the compression rod, and the movable balls are in rolling contact with the limit shell. The movable balls can significantly reduce the friction between the limit shell and the limit shell by using the rolling characteristics, thereby reducing damage. At the same time, the compression rod can be effectively prevented from shaking in the limit shell when subjected to pulling pressure, thereby improving the efficiency of the electric telescopic block being inserted into the groove;

[0019] 4. In the present application, the plug-in end of the electric telescopic card block is set as a rubber head. The rubber has good elasticity and wear resistance, which can reduce the impact force on the groove when it pops out. At the same time, the groove is set to a smooth horizontal funnel shape. The outer surface size is larger than the size of the electric telescopic card block, which is convenient for the insertion of the card block and makes the telescopic component achieve a locking effect. It can effectively prevent the telescopic component from shaking back and forth due to the tension of the plastic enclosure during the unloading process, causing the plastic enclosure to fall off and be damaged.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, a plastic enclosure material feeding equipment comprises a storage device 1, in which U-shaped plastic enclosures 100 are stored, and also comprises a feeding device 2, wherein the feeding device 2 is arranged above the storage device 1, and the feeding device 2 comprises a bracket 21, a transplanting mechanism 22 and a suction cup driving mechanism 23, wherein the transplanting mechanism 22 is fixedly arranged on the bracket 21, and the transplanting mechanism 22 comprises a moving component with two degrees of freedom of movement in the X and Z directions, which are respectively a first transverse slide rail 221, a first slider 222, a first motor 223, a second longitudinal slide rail 224, a second slider 225, and a second motor 226, wherein the first transverse slide rail 221 is fixedly arranged on the bracket 21, and the first transverse slide The rail 221 is slidably connected to the second longitudinal slide rail 224 through the first slider 222, the first transverse slide rail 221 is driven by the first motor 223, the second longitudinal slide rail 224 is slidably connected to the suction cup drive mechanism 23 through the second slider 225, the second longitudinal slide rail 224 is driven by the second motor 226, the suction cup drive mechanism 23 includes a third transverse slide rail 231 and a loading suction cup assembly 232, the third transverse slide rail 231 is fixed on the second slider 225, and is driven by the second motor 226 to slide on the second longitudinal slide rail 224, the third transverse slide rail 231 is connected through a slider to two loading suction cup assemblies 232 with opposite movement directions and capable of rotating 90 degrees.

[0029] like Figure 1-4 As shown, the feeding suction cup assembly 232 includes a mounting frame 2321, a rotating motor 2322, a suction cup 2323, a rotating frame 2324, and a telescopic assembly 2325. The rotating motor 2322 is installed on the mounting frame 2321, and the output end of the rotating motor 2322 is fixedly connected to the rotating frame 2324. Two telescopic assemblies 2325 are installed on the rotating frame 2324. The two telescopic assemblies 2325 are respectively located at the two corners of the plastic enclosure 100. The suction cup 2323 is fixedly installed at one end of the telescopic assembly 2325 away from the rotating motor 2322. When the feeding suction cup assembly 232 is adsorbed, it can adsorb the two corners of the plastic enclosure 100. The suction cup 2323 is elliptical in shape. After the suction cup 2323 is flipped 90 degrees, the short axis of the suction cup 2323 is in the vertical direction. The suction cup 23 The area below 23 is made of a material with lower hardness and easy to deform, and the remaining areas are made of a material with higher hardness and not easy to deform. The present application designs the suction cup 2323 to be an elliptical shape. When the suction cup 2323 is flipped 90 degrees for adsorption, the short axis of the elliptical suction cup 2323 is in the vertical direction. During adsorption, the plastic enclosure 100 in the upper and lower directions of the suction cup 2323 has a certain angle slope. By adopting an elliptical suction cup 2323 with the short axis in the vertical direction, the angle difference can be effectively reduced and adsorption is convenient. During adsorption, the area below the suction cup 2323 preferentially contacts the U-shaped plastic enclosure 100. Therefore, the area below the suction cup 2323 is made of a material with lower hardness and easy to deform, and the remaining areas are made of a material with higher hardness and not easy to deform. This can effectively improve the adsorption capacity and reduce damage to the U-shaped plastic enclosure 100 during adsorption.

[0030] like Figure 1 As shown, the third transverse slide rail 231 includes a laser ranging sensor A2311 and left and right screw rods 2312 with external threads in opposite directions at both ends of the outer ring surface, and the two opposite directions of the external threads of the left and right screw rods 2312 are respectively connected with a left-hand slider 2313 and a right-hand slider 2314 meshing with the external threads, and the left-hand slider 2313 and the right-hand slider 2314 are respectively connected with a loading suction cup assembly 232 and a laser ranging sensor B2315, and the laser ranging sensor A2311 is arranged in the middle position of the third transverse slide rail 231.

[0031] like Figure 2-3As shown, the telescopic component 2325 includes two spring components 24, and the two spring components 24 are symmetrically arranged at the edges of the suction cup 2323. The center point connection line of the two spring components 24 and the suction cup 2323 is in the same straight line as the short axis of the suction cup 2323. When the telescopic component 2325 is parallel to the ground, the center point connection line of the two spring components 24 and the suction cup 2323 is perpendicular to the ground. Since the plastic enclosure 100 is in a U-shaped state when stacked, the suction cup 2323 cannot be completely attached to the plastic enclosure 100 during adsorption. The plastic enclosure 100 is tightly closed, resulting in reduced adsorption efficiency. By symmetrically arranging the two spring components 24 on the edge of the suction cup 2323, when rotating 90 degrees, the two spring components 24 are distributed up and down on the suction cup 2323, so that the bottom suction cup 2323 will first contact the plastic enclosure 100. By continuing to apply pressure, the lower spring component 24 is compressed, so that the upper part of the suction cup 2323 can also contact the plastic enclosure 100, so that the suction cup 2323 can be completely in contact with the plastic enclosure 100, and then adsorption can be performed.

[0032] like Figure 3 and Figure 5As shown, the spring component 24 includes a compression spring 241, a limit shell 242, an electric telescopic block 243, a compression component 244, and a tension pressure sensor 245. The limit shell 242 is fixedly mounted on the rotating frame 2324. The limit shell 242 is a hollow cylinder with a certain thickness. The tension pressure sensor 245 is fixedly mounted on the rotating frame 2324 inside the limit shell 242. The compression spring 241 is fixedly mounted on one end of the tension pressure sensor 245 away from the rotating frame 2324. The compression spring 241 is fixedly mounted on one end of the tension pressure sensor 245 away from the tension pressure sensor 245. The electric telescopic block 243 is provided with a compression component 244. Placed inside the limiting shell 242; the compression component 244 includes a compression rod 2441, a moving ball 2442, and a groove 2443. The compression rod 2441 is connected to the compression spring 241. The compression rod 2441 is provided with a plurality of moving balls 2442 near the end of the compression spring 241. The moving balls 2442 are in rolling contact with the limiting shell 242. The moving balls 2442 can significantly reduce the friction between the limiting shell 242 and the limiting shell 242 by using the rolling characteristics, reduce damage, and can effectively prevent the compression rod 2441 from shaking in the limiting shell 242 when subjected to pulling pressure. The groove 2443 is provided on the compression rod 2441. The groove 2443 is in the shape of a smooth transverse funnel, with a side with a large surface area arranged on the outer surface of the compression rod 2441, and a side with a small surface area arranged inside the compression rod 2441. The end of the groove 2443 is located inside the compression rod 2441 and is in the shape of an arc. The end of the electric telescopic card block 243 close to the compression rod 2441 is in the shape of an arc, and a rubber head is provided at the insertion end of the electric telescopic card block 243. The central axis of the arc of the electric telescopic card block 243 is consistent with the central axis of the arc of the groove 2443. The width of the electric telescopic card block 243 is not greater than the minimum width of the groove 2443, and the total length of the electric telescopic card block 243 when it is ejected is greater than the total length of the groove 2443. The electric telescopic block 243 pops out when the compression spring 241 is not under force, and the plug-in end of the electric telescopic block 243 is set to a rubber head. The rubber has good elasticity and wear resistance, which can reduce the impact force on the groove 2443 when it pops out. At the same time, the groove 2443 is set to a smooth horizontal funnel shape, and the outer surface size is larger than the size of the electric telescopic block 243, which is convenient for inserting the block. The electric telescopic block 243 is inserted into the groove 2443, so that the telescopic component can achieve a locking effect, which can effectively prevent the telescopic component 2325 from shaking back and forth due to the pulling force of the plastic enclosure 100 during the unloading process, causing the plastic enclosure 100 to fall off and be damaged.

[0033] A feeding method for a plastic panel feeding device comprises the following steps:

[0034] S1 positioning, first, the feeding suction cup assembly 232 is moved toward each other to the middle position of the third transverse slide rail 231 through the third transverse slide rail 231, and then, the suction cup drive mechanism 23 is moved to the top of the U-shaped plastic plate 100 through the moving assembly with the freedom of movement in the X and Z directions in the transplanting mechanism 22, and at the same time, it is ensured that after the feeding suction cup assembly 232 is rotated 90 degrees, the height of the suction cup 2323 is lower than the side height of the U-shaped plastic enclosure 100 stacked at the bottom, so as to ensure that it can be adsorbed to each plastic enclosure 100;

[0035] S2 adsorption, through the rotating motor 2322, the rotating frame 2324, the telescopic component 2325 and the suction cup 2323 are driven to rotate 90 degrees towards the plastic panels 100 on both sides, and the pulling pressure sensor 245 is started, and the loading suction cup assembly 232 located in the middle position is moved back to the two sides of the plastic panel 100 through the third transverse slide rail 231 and continues to move back to each other. When the suction cup 2323 contacts the plastic panel 100, the compression spring 241 at the corresponding position of the suction cup 2323 is compressed after being subjected to pressure, and the loading suction cup assembly 232 continues to move back to each other until all the compression springs 241 are compressed by pressure. At this time, the suction cup 2323 is completely in contact with the plastic panel 100, and then the third transverse slide rail 231 stops the loading suction cup 2323 from moving back to each other, and the suction cup 2323 is adsorbed;

[0036] S3 unloading, after the suction cup 2323 absorbs the plastic enclosure 100, the feeding suction cup assembly 232 is moved toward each other through the third transverse slide rail 231, and the absorbed enclosure is moved upward through the transplanting mechanism 22. When the tension pressure sensor 245 detects that there is no force, the electric telescopic block 243 pops up and uses the rebound force of the compression spring 241 to insert into the groove 2443. When the electric telescopic block 243 is inserted into the groove 2443, the third transverse slide rail 231 stops the feeding suction cup assembly 232 from moving toward each other. When the plastic enclosure 100 moves out of the storage device 1, the third transverse slide rail 231 causes the feeding suction cup assembly 232 to move away from each other, and the rotating electric The machine 2322 drives the rotating frame 2324, the telescopic component 2325 and the suction cup 2323 to rotate 90 degrees to present a vertical state. When the rotating frame 2324, the telescopic component 2325 and the suction cup 2323 rotate 90 degrees, the distance measured by the laser ranging sensor A2311 is not less than the distance measured by the laser ranging sensor B2315. When the distances measured by the laser ranging sensor A2311 and the laser ranging sensor B2315 are the same, the opposite movement of the loading suction cup assembly 232 is stopped, and then the plastic enclosure 100 is unloaded by moving downward through the transplanting mechanism 22, and then the electric telescopic block 243 is retracted to close the tension pressure sensor 245.

A feeding method for plastic panel feeding equipment according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1 positioning, first, the feeding suction cup assembly (232) is moved toward each other to the middle position of the third transverse slide rail (231) through the third transverse slide rail (231), and then, the suction cup drive mechanism (23) is moved to the top of the U-shaped plastic plate (100) through the moving assembly with the freedom of movement in the X and Z directions in the transplanting mechanism (22), and at the same time, it is ensured that after the feeding suction cup assembly (232) is rotated 90 degrees, the height of the suction cup (2323) is lower than the side height of the U-shaped plastic enclosure (100) stacked at the bottom, so as to ensure that it can be adsorbed to each plastic enclosure (100); S2 adsorption, through the rotating motor (2322), the rotating frame (2324), the telescopic component (2325) and the suction cup (2323) are driven to rotate 90 degrees towards the plastic panels (100) on both sides, and the tension pressure sensor (245) is started, and the loading suction cup assembly (232) located in the middle position is moved back to the two sides of the plastic panels (100) through the third transverse slide rail (231) and continues to move back to each other. When the suction cup (2323) contacts the plastic panels (100), the compression spring (241) at the corresponding position of the suction cup (2323) is compressed after being subjected to pressure, and the loading suction cup assembly (232) continues to move back to each other until all the compression springs (241) are compressed by pressure. At this time, the suction cup (2323) is completely in contact with the plastic panels (100), and then the third transverse slide rail (231) stops the loading suction cup (2323) from moving back to each other, and the suction cup (2323) is adsorbed; S3 unloading, after the suction cup (2323) absorbs the plastic enclosure (100), the loading suction cup assembly (232) is moved toward each other through the third transverse slide rail (231), and the absorbed enclosure is moved upward through the transplanting mechanism (22). When the tension pressure sensor (245) detects that there is no force, the electric telescopic block (243) pops out and is inserted into the groove (2443) by using the rebound force of the compression spring (241). When the electric telescopic block (243) is inserted into the groove (2443), the third transverse slide rail (231) stops the loading suction cup assembly (232) from moving toward each other. When the plastic enclosure (100) moves out of the storage device (1), the third transverse slide rail (231) causes the loading suction cup assembly (232) to move away from each other and rotate at the same time. The motor (2322) drives the rotating frame (2324), the telescopic assembly (2325) and the suction cup (2323) to rotate 90 degrees to present a vertical state. When the rotating frame (2324), the telescopic assembly (2325) and the suction cup (2323) rotate 90 degrees, the distance measured by the laser distance sensor A (2311) is not less than the distance measured by the laser distance sensor B (2315). When the distances measured by the laser distance sensor A (2311) and the laser distance sensor B (2315) are the same, the reverse movement of the loading suction cup assembly (232) is stopped, and then the plastic enclosure (100) is unloaded by moving downward through the transplanting mechanism (22), and then the electric telescopic block (243) is retracted to close the tension pressure sensor (245).
