[0036] The present invention provides a blanking device 100.

[0037] In the embodiments of the present invention, as Figures 1 - 6 shown, the blanking device 100 includes:

[0038] A blanking frame 10, with a feeding port 11 provided on one side of the blanking frame 10, and a blanking space communicated with the feeding port 11 is provided inside the blanking frame 10;

[0039] A material transporting mechanism 20, the material transporting mechanism 20 is installed inside the blanking frame 10, and the feeding end of the material transporting mechanism 20 is connected to the feeding port 11;

[0040] A lifting mechanism 30, the lifting mechanism 30 is installed on one side inside the blanking frame 10, the lifting mechanism 30 is used to drive the loading device to lift, and the output end of the lifting mechanism 30 has a mounting position 31 for detachably mounting with the loading device;

[0041] A detection device, the detection device is used to detect the change of the sheet material on the loading device; and

[0042] A controller, the controller is respectively connected to the lifting mechanism 30 and the detection device.

[0043] In the technical solution of the present invention, when the sheet material printing machine discharges materials, the detection device detects the change of the sheet material on the material loading device. When the sheet material reaches or is higher than the preset height, the detection device sends a detection signal to the controller, and the controller controls the lifting mechanism 30 to drive the material loading device to descend a preset distance based on the detection signal sent by the detection device, so that the sheet material is lower than the preset height. That is, every time a sheet material is placed on the material loading device, the lifting mechanism 30 drives the material loading device to descend by the height of a sheet material, or at intervals of a preset time, the lifting mechanism 30 drives the material loading device to descend a predetermined height. This cycle continues until the material loading device descends to the preset position, and then one-time material discharging is completed. The automatic material discharging of the sheet material printing machine improves the material discharging efficiency and reduces the labor cost.

[0044] The technical solution of the present invention also adopts a detachable connection between the material loading device and the installation position 31 of the lifting mechanism 30. After the material loading device is full of materials, the material loading device is removed and taken out of the material discharging device 100, and another empty material loading device is installed on the installation position 31. The sheet material printing machine continues to discharge materials, reducing the time for workers to take away the full sheet materials on the material loading device and improving the material discharging efficiency.

[0045] In this embodiment, the height refers to the height of the sheet material relative to the ground, not the height of the sheet material itself.

[0046] In this embodiment, there are two lifting mechanisms 30, which are symmetrically arranged on both sides inside the material discharging frame 10. During material discharging, the two lifting mechanisms 30 are respectively located on both sides of the material loading device; of course, in other embodiments, there can also be only one lifting mechanism 30, but the installation position 31 for installing the material loading device on the lifting mechanism 30 is long enough, and the free end of the installation position 31 exceeds the center line of the material loading device, so that when the material discharging device 100 discharges materials, the material loading device will not tip over; or, there can also be three or more lifting mechanisms 30, but the improvement in the lifting efficiency and fixing effect of the material loading device is not much. Therefore, preferably, the number of the lifting mechanisms 30 is set to two. Compared with using only one lifting mechanism 30 to drive the material loading device to lift and lower, using two lifting mechanisms 30 symmetrically arranged on both sides of the material loading device respectively to drive the material loading device has a greater lifting effect, the material loading device is stressed evenly, and it is more stable during the lifting and lowering process.

[0047] In this embodiment, the detection device is installed on the material discharging frame 10, and the detection device is a diffuse reflection type photoelectric sensor. The photoelectric sensor is arranged on one side of the material loading device. The photoelectric sensor emits light, and the photoelectric sensor itself receives the light reflected back by the sheet material through diffuse reflection. When the photoelectric sensor receives the reflected light, it means that the light emitted by the photoelectric sensor is blocked and reflected by the sheet material, and the height of the sheet material is higher than or equal to the preset height. The detection device sends a detection signal to the controller to control the lifting mechanism 30 to drive the material loading device to descend.

[0048] In other embodiments, the detection device may also be a photoelectric switch, which includes a light emitter and a light receiver. The light emitter and the light receiver are respectively arranged on both sides of the material loading device. When the height of the sheet material is lower than the preset height, the light emitted by the light emitter is received by the light receiver; when the height of the sheet material is higher than or equal to the preset height, the light emitted by the light emitter will be blocked by the sheet material, and the light receiver cannot receive the light emitted by the light emitter. Then, the light receiver sends a detection signal to the controller to control the lifting mechanism 30 to drive the material loading device to descend.

[0049] Further, as Figures 1 - 3 shown, the lifting mechanism 30 includes a mounting member 32, and the mounting member 32 includes a positioning structure. The positioning structure is arranged on the mounting position 31 for positioning the material loading device when the material loading device is detachably mounted on the mounting position 31.

[0050] Specifically, the blanking manipulator has a fixed material taking position. Therefore, when blanking, it is necessary to position the material loading device, and the sheet material on the material loading device also needs to be positioned so that the sheet material is located at the material taking position of the blanking manipulator, ensuring that the blanking manipulator will not deviate during material taking, which is beneficial to the subsequent printing process.

[0051] Further, as Figures 2 - 3 shown, the lifting mechanism 30 includes a mounting member 32, and the mounting member 32 includes a positioning structure. The positioning structure is arranged on the mounting position 31 for positioning the material loading device when the material loading device is detachably mounted on the mounting position 31.

[0052] Specifically, when the material loading device is mounted on the mounting member 32 through the positioning structure, the material loading device can be located below the discharging end of the material transporting mechanism 20. The projection of the material loading device in the vertical direction partially coincides with or the edges are exactly adjacent to the projection of the material transporting mechanism 20 in the vertical direction, preventing the sheet material from not falling onto the material loading device after being transported out from the discharging end of the material transporting mechanism 20.

[0053] Further, as Figures 2 - 3 shown, the positioning structure includes positioning studs 321. The positioning studs 321 are arranged on the surface of the mounting member 32 for mounting with the material loading device, and the positioning studs 321 are used for detachably mounting with the positioning holes at the bottom of the material loading device.

[0054] Specifically, the positioning studs 321 protrude from the surface of the mounting member 32 for mounting with the material loading device, and the positioning holes at the bottom of the material loading device correspond to the shape of the positioning studs 321.

[0055] In this embodiment, the positioning boss 321 is frustum-shaped, and the diameter of the free end of the positioning boss 321 is smaller than the diameter of the orifice of the positioning hole, so that the positioning boss 321 can be inserted into the positioning hole without precise alignment, facilitating the installation of the positioning boss 321 and the positioning hole.

[0056] Of course, in other embodiments, the positioning boss 321 can also be cylindrical, conical, pyramidal, etc.

[0057] In this embodiment, the positioning post extends in the up and down direction on the surface of the mounting member 32 for mounting with the loading device. In other embodiments, the positioning post can extend towards the inside of the blanking space, and the positioning post is used for detachably mounting with the positioning groove at the bottom of the loading device.

[0058] Specifically, the free end of the positioning post extends in the horizontal direction perpendicular to the material conveying direction, and the positioning groove on the bottom plate of the loading device also extends in the horizontal direction perpendicular to the material conveying direction, being adapted to the positioning post. The positioning post can be prism-shaped or cylindrical. The cylindrical positioning post can be installed with the positioning groove at any angle without the need to be adjusted to a specific angle. However, the prism-shaped positioning post needs to be adjusted to an angle adapted to the shape of the positioning groove for installation. Therefore, the cylindrical shape is more convenient for the positioning post to be aligned and installed with the positioning groove at the bottom of the loading device.

[0059] Further, as Figures 2 - 3 shown, the mounting member 32 includes a connecting portion 322 and a mounting portion 323 connected to the connecting portion 322. The connecting portion 322 extends in the lifting direction of the loading device, and the mounting portion 323 extends towards the inside of the blanking space.

[0060] Specifically, the length direction of the mounting portion 323 extends in the horizontal direction perpendicular to the material conveying direction, and the length of the connecting portion 322 extends in the up and down direction. That is, the mounting member 32 is "L"-shaped, with the longer part being the connecting portion 322 and the shorter part being the mounting portion 323.

[0061] The bottom surface of the loading device is mounted with the mounting portion 323, and the side surface abuts against the connecting portion 322. The lifting mechanism 30 drives the loading device to lift by being mounted on the side surface of the loading device, without being mounted directly below the loading device, releasing the space in the lifting direction of the loading device within the blanking device 100, so that the structure of the blanking device 100 can be made more compact, or the loading capacity of the loading device per time can be increased.

[0062] Further, as Figures 2 - 3 shown, the mounting member 32 further includes a mounting plate 324, and the mounting plate 324 is mounted on the mounting portion 323.

[0063] Specifically, the material loading device is detachably installed on the mounting plate 324. The contact area between the mounting plate 324 and the material loading device is larger. Therefore, when the lifting mechanism 30 drives the material loading device to lift, the material loading device can maintain stability and reduce the loosening of the sheet material caused by shaking.

[0064] Further, as Figures 2 - 3 shown, the surface of the mounting plate 324 for mounting the material loading device is a stepped shape that gradually decreases along the extending direction of the mounting portion 323.

[0065] Specifically, the size specifications of the material loading devices are different. The surface of the mounting plate 324 for mounting the material loading device being set as a stepped shape is beneficial to mounting material loading devices with different size specifications. Positioning studs 321 are provided on the surfaces of different steps of the steps. When the material loading device is not mounted on the topmost step, the side wall of the material loading device abuts against the side wall of the upper step. When the material loading device is mounted on the topmost step, the side wall of the material loading device abuts against the side wall of the connecting portion 322, which plays a role in fixing the material loading device.

[0066] Further, as Figures 1 - 3 shown, the lifting mechanism 30 further includes an assembly plate 33, a lifting assembly 34 and a sliding member 35. The assembly plate 33 is mounted on the blanking frame 10. The lifting assembly 34 is mounted on the assembly plate 33. The sliding member 35 is mounted on the output end of the lifting assembly 34. The mounting member 32 is mounted on the sliding member 35.

[0067] Specifically, the lifting assembly 34 drives the sliding member 35 to slide up and down relative to the assembly plate 33. The mounting member 32 is connected to the sliding member 35 to drive the mounting member 32 to move in the up and down direction, thereby driving the material loading device mounted on the mounting member 32 to lift.

[0068] The lifting assembly 34 can be a motor screw mechanism, and the sliding member 35 is connected to the output end of the motor screw mechanism; the lifting assembly 34 can also be a motor gear and rack mechanism, and the sliding member 35 is connected to the output end of the motor gear and rack mechanism; the lifting assembly 34 can also be a cylinder mechanism, and the output end of the cylinder mechanism is connected to the sliding member 35, or other structures capable of driving the material loading device to lift.

[0069] Further, as Figures 2 - 3 shown, the lifting assembly 34 includes a driving member 341, a transmission member 342 and a driven member 343. The driving member 341 is mounted on the side of the assembly plate 33 away from the mounting member 32. The driven member 343 is mounted on the side of the assembly plate 33 facing the mounting member 32. The transmission member 342 is respectively connected to the output end of the driving member 341 and the input end of the driven member 343. The sliding member 35 is mounted on the output end of the driven member 343.

[0070] In this embodiment, the driving member 341 includes a motor fixed on the assembly plate 33, the driven member 343 includes a screw rod and a nut sleeve sleeved on the screw rod, both ends of the screw rod are fixed on the assembly plate 33, the nut sleeve is connected to the sliding member 35, the transmission member 342 is a belt, one end of the belt is connected to the output end of the motor, and the other end is connected to the input end of the screw rod. The rotation output of the screw rod and the nut sleeve is converted into a linear output.

[0071] Of course, in other embodiments, the transmission member 342 can be set as a gear set. A driving gear is installed on the output end of the motor, a driven gear is installed on the input end of the screw rod, and a transmission gear is installed between the driving gear and the driven gear. The power of the motor is transmitted to the screw rod through the meshing of the driving gear and the transmission gear, and the meshing of the transmission gear and the driven gear.

[0072] Further, as Figures 2 - 3 shown, the sliding member 35 includes a slide rail 351 and a slider 352 movably installed on the slide rail 351. The slide rail 351 is connected to one side of the assembly plate 33 facing the loading device. The slider 352 is connected to the output end of the driven member 343. The slider 352 is provided with a chute, and the groove surface of the chute is slidably connected to the surface of the slide rail 351, so that the slider 352 is movably connected to the slide rail 351. Concave snap grooves 353 are formed in the side wall surfaces on both sides of the slide rail 351, and snap convex portions 354 are formed by the arching of the groove surfaces on both sides of the chute. The snap convex portions 354 are connected to the snap grooves 353.

[0073] Specifically, the number of the sliding members 35 is two, which are respectively arranged on both sides of the driven member 343.

[0074] The slide rail 351 extends in the up and down direction. The slider 352 is connected to the nut sleeve. When the screw rod rotates, the nut sleeve moves up and down, driving the slider 352 to move up and down. The slider 352 is connected to the mounting member 32, so that the loading device on the mounting member 32 moves up and down in the up and down direction.

[0075] The mounting member 32 is installed on the slider 352. Compared with the mounting member 32 being installed on the nut sleeve, it reduces part of the vibration caused by the cooperation of the screw rod and the nut sleeve, making the mounting member 32 move more smoothly.

[0076] The slider 352 is connected to the mounting member 32, and the slider 352 will receive a large horizontal component force perpendicular to the length extension direction of the slide rail 351. The slider 352 and the slide rail 351 are matched by the snap convex portion 354 and the snap groove to prevent the slider 352 from disengaging from the slide rail 351, ensuring the smooth sliding of the slider 352 on the slide rail 351.

[0077] Further, as Figure 1As shown, the blanking device 100 further includes a bracket 51 installed on the blanking frame 10, a first pushing drive member 341 installed on the bracket 51, and a first pushing plate 52 installed at the output end of the first pushing drive member 341. The first pushing plate 52 is used to align the sheet materials on the loading device.

[0078] Specifically, the first pushing drive member 341 is a cylinder, and the driving direction of the cylinder is the horizontal direction perpendicular to the feeding direction, so as to drive the first pushing plate 52 to move in the horizontal direction perpendicular to the feeding direction, and align the sheet materials on the loading device in the horizontal direction perpendicular to the feeding direction.

[0079] Further, as Figure 1 shown, a plurality of convex strips 521 are formed by the spaced protrusions on the lower edge of the first pushing plate 52, so as to be arranged alternately with a plurality of slats installed at intervals on the upper surface of the loading device. The slats extend in the horizontal direction perpendicular to the feeding direction.

[0080] Specifically, the distances between the convex strips 521 are equal, and the distances between the slats are equal. When the loading device is at the highest position, the convex strips 521 are alternately inserted into the intervals between the slats, preventing the sheet materials from passing through the gap between the lower edge of the first pushing plate 52 and the upper surface of the loading device when the first pushing plate 52 is pushing the materials, and the sheet materials not being pushed away by the first pushing plate 52, resulting in the sheet materials not being aligned.

[0081] Further, as Figures 4 - 6 shown, the blanking device 100 further includes a flat plate 61 installed on the blanking frame 10, a second pushing drive member 341 installed on the flat plate 61, a pushing slide rail 63 installed on the flat plate 61, and a pushing rod 64 installed at the output end of the second pushing drive member 341. The pushing rod 64 is slidably installed on the pushing slide rail 63. The pushing rod 64 is arranged in a staggered manner with the material conveying mechanism 20. The pushing rod 64 is used to align the sheet materials on the material conveying mechanism 20.

[0082] In this embodiment, the second pushing drive member 341 includes a second pushing motor installed on the flat plate 61, a pushing slide block 622 slidably installed on the pushing slide rail 63, a runner 623 installed on the flat plate 61, a pushing belt 624 with one end connected to the runner 623 and the other end connected to the output end of the motor, and a connecting block 625 respectively connected to the pushing slide block 622 and the pushing belt 624. The pushing rod 64 is installed on the pushing slide block 622. The pushing slide rail 63 extends in the horizontal direction perpendicular to the sheet material feeding direction. The motor drives the belt to rotate, so that the connecting block 625 moves in the horizontal direction perpendicular to the sheet material feeding direction, driving the pushing slide block 622 to move in the horizontal direction perpendicular to the sheet material feeding direction, so as to align the sheet materials on the material conveying mechanism 20 in the horizontal direction perpendicular to the sheet material feeding direction.

[0083] Of course, in other embodiments, the second pusher driving member 341 may be a component with linear output such as a cylinder, a motor screw mechanism, a motor rack and pinion mechanism, etc.

[0084] Furthermore, as Figure 4 shown, the blanking device 100 further includes a third pusher driving member 71 installed on the lower side of the material transporting mechanism 20 and a third pusher plate 72 installed on the output end of the third pusher driving member 71.

[0085] Specifically, the third pusher driving member 71 is a cylinder, and the driving direction of the cylinder is the sheet material feeding direction, so as to drive the third pusher plate 72 to move along the sheet material feeding direction, and push the sheet material on the material loading device neatly in the sheet material feeding direction.

[0086] Furthermore, as Figure 4 shown, the material transporting mechanism 20 includes a mounting bracket 21 installed on the feeding frame, a first material transporting component 22 and a second material transporting component 23 installed on the mounting bracket 21 in sequence along the sheet material feeding direction, and a material transporting driving member 24 for jointly driving the first material transporting component 22 and the second material transporting component 23.

[0087] Specifically, the feeding end of the first material transporting component 22 is communicated with the feeding port 11, the discharging end of the first material transporting component 22 corresponds to the feeding end of the second material transporting component 23, the sheet material enters from the feeding port 11, is transported by the first material transporting component 22 and the second material transporting component 23 to the discharging end of the second material transporting component 23, and the sheet material falls from the discharging end of the second material transporting component 23 to the material loading device.

[0088] The output end of the material transporting driving member 24 is connected to the input end of the second material transporting component 23, and a roller 25 is further connected to the output end of the material transporting driving member 24. The roller 25 is in transmission connection with the input end of the first material transporting component 22. Only by setting one driving member 341 can the two material transporting components be driven to operate simultaneously, reducing the part cost and the installation space.

[0089] Furthermore, as Figures 4 - 5 shown, the first material transporting component 22 includes a plurality of first rollers 221 whose two ends can be rotatably connected to the mounting bracket 21, driven wheels 222 installed at both ends of the first rollers 221, and a leather belt 223 connecting the adjacent driven wheels 222 in transmission;

[0090] The second material transporting component 23 includes a plurality of second rollers 231 whose two ends can be rotatably connected to the mounting bracket 21, and a plurality of material transporting belts 232 whose two ends are respectively installed on the two second rollers 231.

[0091] In this embodiment, the structures of the first material transporting component 22 and the second material transporting component 23 are different, but in other embodiments, the structures of the first material transporting component 22 and the second material transporting component 23 may be the same.

[0092] Specifically, both the first roller 221 and the second roller 231 extend along the horizontal direction perpendicular to the sheet feeding direction, and the material conveying belt 232 is arranged along the sheet feeding direction.

[0093] In the first material conveying assembly 22, the first roller 221 adjacent to the second material conveying assembly 23 is the driving member, and is drivingly connected to the roller 25 at the output end of the material conveying driving member 24 through the driven wheel 222 of this driving member to obtain power. The driven wheels 222 of the remaining first rollers 221 in the first material conveying assembly 22 are drivingly connected to the driven wheel 222 connected to the roller 25 to obtain power.

[0094] In the second material conveying assembly 23, the second roller 231 connected to the output end of the material conveying driving member 24 is the driving member, and the remaining second rollers 231 obtain power from this driving member through the material conveying belt 232.

[0095] Further, as Figures 4 - 6 shown, a plurality of first rollers 221 are arranged along the sheet feeding direction. On the outer side of the mounting bracket 21 and below the first rollers 221, two secondary driven wheels 224 are further provided. The two secondary driven wheels 224 are arranged in the vertical direction, and are drivingly connected to the driven wheels 222 of the first rollers 221 on both sides, which can increase the wrap angle between the leather strip 223 and the driven wheel 222 and improve the transmission force.

[0096] Further, as Figures 4 - 6 shown, the mounting bracket 21 is connected with an adjusting frame 26, which is located below the second material conveying assembly 23. The second material conveying assembly 23 further includes an adjusting roller 233 movably mounted on the adjusting frame 26. The adjusting roller 233 is drivingly connected to the second roller 231 through the material conveying belt 232.

[0097] Specifically, the adjusting roller 233 moves in the vertical direction. By adjusting the position of the adjusting roller 233, the tension of the material conveying belt 232 is adjusted to maintain the transmission force.

[0098] Further, as Figures 4 - 6 shown, a shielding plate 27 is mounted on the mounting bracket 21. The shielding plate 27 is located above the first material conveying assembly 22 and the second material conveying assembly 23 to prevent the sheet from flipping upwards during transportation.

[0099] Further, as Figure 4 shown, a material arrival sensor 28 is mounted on the shielding plate 27 near the feeding port 11. The material arrival sensor 28 is connected to the controller.

[0100] Specifically, when the upstream device of the blanking device 100 sends a sheet material, the material arrival sensor 28 detects that the sheet material enters the feeding end of the material transporting mechanism 20. The material arrival sensor 28 sends a material arrival signal to the controller, and the controller controls the material transporting driving member 24 to drive the first material transporting assembly 22 and the second material transporting assembly 23 to operate based on the material arrival signal sent by the material arrival sensor 28, so as to transport the sheet material to the material loading device.
