Detailed implementation manners

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0026] As Figure 1 , Figure 2As shown in the figure, the sheet sorting mechanism of this embodiment includes: a flipping platform 100, a sheet pressing component 200, and a vibration component 300. The flipping platform 100 is used to carry the material box 10, and the sheet 20 is arranged in the material box 10. The flipping platform 100 has a first position and a second position. When the flipping platform 100 is in the first position, the flipping platform 100 is horizontally arranged to receive the material box 10 on the horizontal plane; when the flipping platform 100 is in the second position, the flipping platform 100 is vertically arranged to flip the material box 10 into a vertical state, and the sheet 20 in the material box 10 is also flipped into a vertical state. The sheet pressing component 200 is slidably installed on the flipping platform 100 and can be flipped along with the flipping of the flipping platform 100. The sheet pressing component 200 includes a pressing plate 210 and a plurality of rollers 220. The plurality of rollers 220 are rotatably installed on the pressing plate 210. The roller surfaces protrude from the surface of the pressing plate 210 facing the flipping platform 100 and are in rolling contact with the sheet 20. The pressing plate 210 can be driven to move along a first direction A, approaching or moving away from the flipping platform, driving the rollers 220 to press the sheet 20 gently; the pressing plate 210 can also be driven to move along a second direction B to avoid the material box, preventing the pressing plate 210 from affecting the placement of the material box 10 on the flipping platform 100. The first direction A is perpendicular to the horizontal plane, and the second direction B is perpendicular to the first direction A. The vibration component 300 is used to drive the sheet 20 to move along the first direction A when the flipping platform 100 is in the second position. When the flipping platform 100 is in the first position, the material box 10 is placed on the flipping platform 100, and the sheet pressing component 200 drives the pressing plate 210 to drive the rollers 220 to move towards the sheet 20. The rollers 220 are in contact with the sheet 20 to prevent the flipping platform 100 from flipping and the sheet 20 from falling out of the material box 10 after flipping in place. The flipping platform 100 is flipped to the second position, and the material box 10 and the sheet 20 in the material box 10 are vertically arranged. The vibration component 300 drives the sheet 20 to move in the first direction A. The multiple movements of the sheet 20 make the sheet 20 neat. During the vertical movement of the sheet 20, the outermost sheet 20 is in rolling contact with the rollers 220. The axial direction of the rollers 220 is perpendicular to the first direction A, reducing the friction force and improving the sorting effect of the sheet 20.

[0027] Furthermore, the rollers 220 are in floating contact with the sheet 20. After the rollers 220 are in contact with the sheet 20, there is a certain floating amount in the first direction A, avoiding hard contact between the rollers 220 and the sheet 20 and damaging the sheet 20. And when the flipping platform 100 is in the second position, during the movement of the sheet 20 along the first direction A, there is a certain gap between the sheets 20, which is more conducive to the sorting of the sheet 20.

[0028] Specifically, as Figure 3As shown, the roller 220 is rotatably connected to the pressure plate 210. The pressure component 200 further includes a connecting arm 230. The pressure plate 210 and the connecting arm 230 are floatingly connected by a plurality of support members 240. The connecting arm 230 is rotatably connected to the pressure plate 210. Mounting grooves 231 are provided on the surfaces of the connecting arm 230 and the pressure plate 210 facing each other. Support members 240 are provided in the mounting grooves 231. The support members 240 are preferably springs.

[0029] Referring again to Figure 1 As shown, the pressure component 200 further includes a first driving member 250 and a second driving member 260. The second driving member 260 is mounted on the flipping platform 100. The second driving member 260 is preferably a rodless cylinder, and its driving direction is set along the second direction B, driving the pressure plate 210 to move along the second direction B to avoid the material box 10. The driving end of the second driving member 260 mounts the first driving member 250. The first driving member 250 is preferably a combination of a motor and a lead screw, and its driving direction is set along the first direction A, driving the pressure plate 210 to move along the first direction A to approach or move away from the sheet 20.

[0030] The upper surface of the flipping platform 100 is provided with a fixed clamping block 110 and a movable clamping block 120. The two clamping blocks cooperate with each other to clamp the opposite sides or opposite corners of the material box 10. When the flipping platform 100 is in the second position, the two clamping blocks are arranged vertically. The fixed clamping block 110 is used to support the material box 10, and the movable clamping block 120 is used to cooperate with the fixed clamping block 110 to clamp the material box 10. In this embodiment, the flipping platform 100 rotates about the diagonal axis. There are two fixed clamping blocks 110, which are installed on the flipping platform 100. The two fixed clamping blocks 110 form a right-angle surface to abut against a corner of the material box 10. There is one movable clamping block 120, which has a right-angle surface and is used to abut against the other corner of the material box 10 opposite to the fixed clamping block 110. The movable clamping block 120 is connected to a third driving member 121. The third driving member 121 is preferably a cylinder and is installed on the lower surface of the flipping platform 100, driving the movable clamping block 120 to approach or move away from the material box 10 to clamp or release the material box 10, and can adapt to material boxes 10 of different sizes. The third driving member 121 is installed on the lower surface of the flipping platform 100, which can save space.

[0031] In other embodiments, the flipping platform 100 can also rotate about the central axis of both sides. At this time, the fixed clamping block 110 and the movable clamping block 120 have flat surfaces to abut against the opposite sides of the material box.

[0032] The upper surface of the flipping platform 100 is further provided with a fourth driving member 130. The driving end of the fourth driving member 130 is connected to a first pressing plate 131. The driving direction of the fourth driving member 130 faces the edge of the sheet 20. The fourth driving member 130 is preferably a cylinder, which drives the first pressing plate 131 to press the sheet 20. A plurality of air blowing holes 132 are provided on the surface of the first pressing plate 131 facing the sheet 20. An external positive pressure device is connected to blow air towards the sheet 20, and the sheet 20 is dispersed during the movement of the sheet 20 along the first direction A.

[0033] There are two fourth driving members 130, which are located on two adjacent sides of the sheet 20. And when the flipping platform 100 is in the second position, the fourth driving members 130 are located above the material box 10 to align the sheet 20 towards the same corner.

[0034] The upper surface of the flipping platform 100 is further provided with a fifth driving member 140. The fifth driving member 140 is preferably a clamping cylinder, and its driving end is connected to a second pressing plate 141, which drives the second pressing plate 141 to flip and clamp the material box 10 towards the flipping platform 100.

[0035] Reference Figure 1 、 Figure 4 As shown, a pallet 150 is slidably arranged on the upper surface of the flipping platform 100, and the pallet 150 can be driven to be inserted between the material box 10 and the sheet 20. In this embodiment, one corner of the sheet 20 facing the material box is aligned. There are two pallets 150, and the two pallets 150 are vertically arranged to support the downward corner of the flipped sheet 20. In other embodiments, if one side of the sheet 20 facing the material box is aligned, the pallet 150 supports the downward side of the flipped sheet 20.

[0036] The mounting method of the pallet 150 is as follows: The pallet 150 is mounted on a mounting base 151. The mounting base 151 is slidably mounted on a mounting plate 153 through a first slide rail 152. A sixth driving member 154 is also provided on the mounting plate 153. The sixth driving member 154 is preferably a rodless cylinder, and its driving direction is perpendicular to the flipping platform 100, driving the pallet 150 to approach or move away from the flipping platform 100. The mounting plate 153 is slidably mounted on the flipping platform 100 through a second slide rail 155. A seventh driving member 156 is provided on the lower surface of the flipping platform 100. The seventh driving member 156 is preferably a cylinder, and its driving direction is parallel to the flipping platform 100. When the flipping platform 100 is in the first position, the extending direction of the first slide rail 152 and the driving direction of the sixth driving member 154 are both set along the first direction A, and the extending direction of the second slide rail 155 and the driving direction of the seventh driving member 156 are both set along the third direction C. The seventh driving member 156 drives the pallet 150 to move along the third direction C, and the third direction C is perpendicular to the first direction A and the second direction B. When the flipping platform 100 is in the second position, the extending direction of the first slide rail 152 and the driving direction of the sixth driving member 154 are changed to be along the third direction C, and the extending direction of the second slide rail 155 and the driving direction of the seventh driving member 156 are changed to be along the first direction A.

[0037] The vibration assembly 300 includes a push plate 310. When the flipping platform 100 is in the second position, the push plate 310 can be driven to reciprocate along the first direction A and lift the sheet 20 through the opening 11 provided at the edge of the material box 10. There are four openings 11, which are respectively located on the side surfaces of the material box 10. There are two push plates 310, which are commonly connected to the same sliding plate 320. The sliding plate 320 is connected to an eighth driving member 330. The eighth driving member 330 is mounted on the lower surface of the flipping platform 100. The eighth driving member 330 is preferably a motor and lead screw assembly. When the flipping platform 100 is in the first position, the driving direction of the eighth driving member 330 is set along the third direction C. After the flipping platform 100 is flipped to the second position, the driving direction of the seventh driving member 156 is changed to be along the first direction A.

[0038] After the flipping platform 100 is flipped, the seventh driving member 156 drives two push plates 310 to extend into the cartridge 10 from the openings 11 on the adjacent sides of the cartridge 10, lift the sheet 20, and the seventh driving member 156 drives the two supporting plates 150 to slide along the second slide rail 155 and approach the cartridge 10. The sixth driving member 154 drives the two supporting plates 150 to slide along the first slide rail 152 and insert between the sheet 20 and the cartridge 10. The seventh driving member 156 drives the two push plates 310 to repeatedly lift the sheet 20 to align the sheet 20. Since there is a foam between the cartridge 10 and the sheet 20, without the setting of inserting the supporting plate 150 between the sheet 20 and the cartridge 10, the existence of the foam will affect the alignment effect of the sheet 20. The insertion of the supporting plate 150 between the sheet 20 and the cartridge 10 also extends the edge length of the cartridge 10, better supports the sheet 20, and prevents the sheet 20 from falling off.

[0039] An air blowing hole can also be provided at one end of the push plate 310 facing the sheet 20, externally connected to a positive pressure device to blow air towards the sheet 20. During the process of aligning the sheet 20, the sheet 20 is blown to prevent adjacent sheets 20 from clinging to each other and affecting the alignment effect.

[0040] The vibration assembly 300 can also select an electromagnetic vibrator to directly drive the vibration of the flipping platform 100.

[0041] The bottom surface of the cartridge 10 is provided with a hollow part communicating with each opening 11; the flipping platform 100 is provided with a through hole 160, and a sensor 170 is installed on the lower surface of the flipping platform 100 to detect whether the sheet 20 is aligned in place. The sensor 170 selects a laser sensor, and the installation position of the sensor 170 on the flipping platform 100 can be changed according to the size of the sheet 20. The light of the sensor 170 passes through the through hole 160 and the hollow part. Both the through hole 160 and the sensor 170 are provided with two. When the flipping platform 100 is in the second position, the sensors 170 are both located above the edge of the sheet 20. When the sheet 20 is aligned in place, the light of the sensor 170 is not blocked, and the sensor 170 can transmit a signal to the controller, and the controller controls the sheet aligning mechanism to perform the next operation.

In this embodiment, the connecting arm 230 is fixedly connected to the pressing plate 210, the rollers 220 are connected to both ends of the first shaft body 270, and the first shaft body 270 is rotatably connected to the pressing plate 210. A groove is provided on the lower surface of the pressing plate 210, and the first shaft body 270 is floatingly connected to the pressing plate 210 through a support member 240. The support member 240 is preferably a spring, one end of the spring abuts against the groove, and the other end abuts against the first shaft body 270.

[0043] As Figure 6As shown in the figure, it is a structural diagram of the material pressing assembly 200 of the third embodiment of the present utility model. The roller 220 is rotatably installed on a connecting plate 280. The connecting plate 280 is rotatably connected to the material pressing plate 210 through a second shaft body 290.
