[0033] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0034] As Figures 1 to 5 shown, the present utility model discloses a sheet material transportation and feeding device, which includes a base 1. Four pulleys 2 are rotatably provided at the bottom of the base 1, and a push frame 3 is provided on the side wall of the base 1.

[0035] A plurality of connecting screws are vertically provided on the top of the base 1. The plurality of connecting screws are arranged in a matrix and the arrangement area is rectangular. Vertically arranged driving screws 6 are respectively rotatably provided on the base 1 outside the four corners of the arrangement area of the connecting screws. A motor 8 is provided at the bottom of the base 1 as a driving source. A transmission assembly is provided between the motor 8 and the four driving screws 6, and the motor 8 drives the four driving screws 6 to rotate synchronously through the transmission assembly.

[0036] The transmission assembly includes a main transmission shaft 9 rotatably provided in the base 1. Sub-transmission shafts 10 perpendicular to it are rotatably provided in the base 1 above both ends of the main transmission shaft 9. The main transmission shaft 9 is provided above the output shaft of the motor 8. A first worm is coaxially provided on the output shaft of the motor 8. A first worm gear meshing with the first worm is coaxially provided at the corresponding position on the main transmission shaft 9. Second worms are respectively coaxially connected to both ends of the main transmission shaft 9. Second worm gears meshing with the second worms are respectively coaxially connected to the corresponding positions on the two sub-transmission shafts 10. Third worms are respectively coaxially connected to both ends of the two sub-transmission shafts 10. Third worm gears 11 meshing with the four third worms are respectively rotatably provided in the base 1 on the sides of the four third worms. The four third worm gears 11 are respectively coaxially connected to the four driving screws 6. When the motor 8 operates, the main transmission shaft 9 is driven to rotate through the transmission connection between the first worm gear and the first worm. The two sub-transmission shafts 10 are driven to rotate synchronously through the transmission between the second worms and the second worm gears at both ends of the main transmission shaft 9. The four driving screws 6 are driven to rotate synchronously through the transmission connection between the third worms and the third worm gears when the two sub-transmission shafts 10 rotate synchronously.

[0037] A material plate 4 is provided on the base 1. A plurality of sliding holes 42 arranged in a matrix are provided on the material plate 4. The arrangement area of the sliding holes 42 is rectangular. The positions of the plurality of sliding holes 42 on the material plate 4 respectively correspond to the plurality of connecting screws. Four screw holes 41 respectively threadedly engaged with the four driving screws 6 are also provided at the corresponding positions on the material plate 4. After the four screw holes 41 on the material plate 4 are threadedly engaged with the four driving screws 6, the plurality of sliding holes 42 on the material plate 4 are respectively coaxial with the plurality of connecting screws on the top of the base 1.

[0038] A plurality of surrounding rods 5 are provided at the top of the base 1. The outer diameter of the surrounding rod 5 is adapted to the inner diameter of the sliding hole 42. The surrounding rod 5 includes a sleeve 51 at its bottom and a detection rod 53 at its top. The sleeve 51 is in threaded fit with the connecting screw. A plurality of short rods 52 are provided between the sleeve 51 and the detection rod 53. The plurality of short rods 52 are coaxially threaded together in sequence from head to tail. The lowermost short rod 52 is coaxially threaded to the top of the sleeve 51, and the uppermost short rod 52 is coaxially threaded to the bottom of the detection rod 53. The length of the surrounding rod 5 can be adjusted by increasing or decreasing the number of short rods 52.

[0039] The surrounding rod 5 passes through the sliding hole 42 and can be in threaded connection with the connecting screw directly below the sliding hole 42. The surrounding rod 5 not only serves as a fence for the plates on the material plate 4, but also realizes guiding when the material plate 4 is lifted or lowered through the sliding connection between the surrounding rod 5 and the sliding hole 42, so that the material plate 4 is lifted and lowered vertically. In this embodiment, three surrounding rods 5 are equidistantly arranged in the two length directions of the plate, and two surrounding rods 5 are arranged in the two width directions of the plate. The ten surrounding rods 5 are respectively in contact with the side walls of the plate to fence it, and the plate is fixed when placed between the ten surrounding rods 5.

[0040] A position detection unit is provided in the detection rod 53. The position detection unit detects the position of the plate. The position detection unit includes a through hole 13 provided on the inner wall of the detection rod 53 in contact with the plate. A hemispherical detection ball 12 is provided in the through hole 13. The inner diameter of the through hole 13 is smaller than the diameter of the detection ball 12, so that when the detection ball 12 slides outward in the through hole 13, only part of the spherical body of the detection ball 12 can pass through the through hole 13 and be outside the detection rod 53. A plurality of first spring telescopic rods 14 are provided on the inner side wall of the detection ball 12. The end of the first spring telescopic rod 14 away from the detection ball 12 is fixed in the detection rod 53. Under the elastic force of the first spring telescopic rod 14, the detection ball 12 remains in contact with the through hole 13, and the detection ball 12 is exposed outside the through hole 13 to the greatest extent. Second spring telescopic rods 16 and third spring telescopic rods 15 are also provided on the inner side wall of the detection ball 12 and are arranged parallel to the first spring telescopic rod 14. A first touch switch 17 and a second touch switch 18 are respectively provided in the detection rod 53 in the sliding direction of the second spring telescopic rod 16 and the third spring telescopic rod 15 and are matched with them. A controller 19 electrically connected to the first touch switch 17 and the second touch switch 18 is also provided in the detection rod 53. The controller 19 is electrically connected to the motor 8. The distance between the second touch switch 18 and the detection ball 12 is greater than the distance between the first touch switch 17 and the detection ball 12. When the detection ball 12 slides inward, the second spring telescopic rod 16 contacts the first touch switch 17 first. As the detection ball 12 continues to slide inward, the third spring telescopic rod 15 contacts the second touch switch 18 only then.

[0041] A suction cup mechanism 7 that can move in three directions is arranged at the feeding place of the processing equipment. The suction cup mechanism 7 includes a suction cup frame. A plurality of suction cups are arranged at the bottom of the suction cup frame. The suction cup frame is driven by a three-way driving mechanism to move in three directions. The motor 8 runs to drive the material plate 4 to rise, and the stacked plates on the material plate 4 rise accordingly. After the suction cup mechanism 7 adsorbs the topmost plate, it transfers it to the processing equipment for feeding.

[0042] The working process of the present utility model is as follows:

[0043] According to the size of the plate, the positions of a plurality of surrounding rods 5 are set to ensure that when the plates are stacked on the material plate 4, there are surrounding rods 5 on each side of the plate for enclosure. According to the stacking height of the plates, the number of short rods 52 is adjusted to control the length of the surrounding rods 5. If the operation of placing the plates on the material plate 4 is manual work, the enclosure on one side can be removed to facilitate feeding. After the plates are stacked, a plurality of surrounding rods 5 on this side are connected to the base 1;

[0044] The device is pushed to the processing equipment by the pushing frame 3. The suction cup mechanism 7 adsorbs the plate and feeds the plate into the processing equipment. The topmost plate is first sucked out of the device vertically upward. During the process that the plate rises and slides past the detection ball 12, after the side of the plate slides past the detection ball 12, it pushes the detection ball 12 inward and compresses the first spring telescopic rod 14 until the third spring telescopic rod 15 contacts the second touch switch 18. The second touch switch 18 transmits an electrical signal to the controller 19. The controller 19 controls the motor 8 to run, and the four driving screws 6 rotate to drive the material plate 4 to rise. After the plate leaves the detection ball 12, the detection ball 12 resets under the elastic force of the first spring telescopic rod 14, and most of the detection ball 12 exposes outside the through hole 13. As the material plate 4 rises, the topmost plate first contacts the lower part of the detection ball 12. As the material plate 4 continues to rise, the topmost plate gradually pushes the detection ball 12 to slide inward. Since the distance between the second touch switch 18 and the detection ball 12 is greater than the distance between the first touch switch 17 and the detection ball 12, the second spring telescopic rod 16 first contacts the first touch switch 17. The first touch switch 17 transmits an electrical signal to the controller 19, and the controller 19 controls the motor 8 to stop, so as to realize the positioning of the height of the plate, so that the suction cup mechanism 7 can adsorb the plate every time it descends the same height, not only avoiding the plate being pushed out of the device due to excessive rise of the material plate 4, but also because the plate can be positioned, different thickness plates can be stacked on the material plate 4.

[0045] The utility model can adjust the arrangement mode and length of the surrounding rod 5 according to the size and stacking height of the plate, can accommodate different plates and allow different stacking heights, has a wide application range, and can automatically suck out the plates stacked on the material plate 4 and feed them to the processing equipment through cooperation with the suction cup mechanism 7. The position detection unit provided on the upper part of the surrounding rod 5 can position the plate to be adsorbed. A variety of plates with different stacking thicknesses can be mixed and stacked in the material plate 4, and the suction cup mechanism 7 cooperates to perform automatic feeding, improving the operation efficiency and reducing the labor intensity of workers.

[0046] The above embodiments are only the preferred embodiments of the utility model, and do not limit the technical solution of the utility model. As long as the technical solution can be realized on the basis of the above embodiments without creative labor, it shall be regarded as falling within the scope of the patent right of the utility model.
