Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to a clamping reversing conveying device. Background Art

[0002] In the field of production line transportation, the transportation of boxes is inseparable from the production line. When some boxes need to be turned, they are generally moved manually and transported to another production line. However, the manual turning of the boxes has high labor intensity, low automation, and low transportation efficiency. In order to solve this problem, a rotating line structure is introduced in the field of production line transportation, but the existing rotating conveyor line structure often uses a motor to drive a gear sprocket or a right-angle roller conveyor line to rotate, which has a slow rhythm and high equipment cost. During the rotation process, the box is prone to shaking and moving out of position. When the next station equipment needs precise positioning accuracy, it cannot meet the requirements and cannot meet the current production line transportation needs. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention is further described below through specific implementation methods.

When the slot-type photoelectric sensors 6 detect a signal that the box on the conveyor belt 3 reaches the reversing station, the clamping and correction mechanism 4 works to clamp the box on the conveyor belt 3 and cooperates with the driving mechanism 5 to realize rapid reversal of the box without shaking during the reversing process, and can provide position accuracy for the next station to ensure accurate conveying of the box.

[0022] The base 1 includes a rotating base 11 for supporting the rotating disk 2 and a plurality of supporting spacers 12 circumferentially distributed between the rotating disk 11 and the base 1, wherein the base 1 can be installed on the ground through a plurality of adjusting bases 13, and the height can be adjusted by adjusting the bases 13 to adapt to the height of different production conveyor lines.

[0023] The rotating disk 2 comprises a rotating disk body 21 rotatably disposed on the rotating seat 11 , and a bracket plate 22 disposed on the top of the rotating disk body 21 for mounting the conveyor belt 3 and the clamping and correcting mechanism 4 .

[0024] The clamping and correction mechanism 4 clamps the box entering the conveyor belt 3 and corrects its conveying position, including two clamping plates 41 arranged on the rotating disk 2 and movable toward or away from each other, a moving member 42 arranged on the rotating disk 2 and connected to drive the two clamping plates 41 to move, and two guiding members 43 respectively arranged at the upper ends of the two clamping plates 42; wherein, the upper end of the clamping plate 41 extends upward through the conveyor belt 3 and is located on the inner side of the conveyor belt 3, including a clamping plate body 411 and a plurality of clamping rods 412 arranged at intervals on the clamping plate body 411 and passing through the conveyor belt 3.

[0025] The moving part 42 includes a moving motor 421 arranged on the rotating disk 2, a moving screw rod 422 connected to the moving motor 421, a first nut seat 423 and a second nut seat 424 respectively arranged on the two clamping plates 41 and cooperating with the moving screw rod 422, two mounting plates 425 arranged on the rotating disk 2 and located on the outside of the conveyor belt 3, two guide rods 426 arranged between the two mounting plates 425 and located on both sides of the moving screw rod 422, and two guide seats 427 respectively arranged on the clamping plates 41 and cooperating with the two guide rods 426; wherein, the thread setting directions of the first nut seat 423 and the second nut seat 4424 are opposite.

[0026] The guide member 43 is arranged between multiple clamping rods 412, and includes a guide plate 431 arranged at the upper ends of the multiple clamping rods 412, a multiple guide wheels 432 arranged at intervals along the length direction of the guide plate 431, and a guide plate 433 inclined outward at the front end of the guide plate 431. The two guide plates 433 inclined outward cooperate with the multiple guide wheels 432 to guide the box body to enter between the two clamping plates 41; wherein, the slot-type photoelectric sensor 6 is arranged at the rear end of the clamping plate 41, and is arranged in front and behind the guide plate 433 on the same side.

[0027] The driving mechanism 5 includes a driving cylinder 51 arranged on the base 1 and connected to the rotating disk 2, a connecting plate 52 arranged at the bottom of the rotating disk 2 and movably connected to the driving cylinder 51, a limiting component 53 arranged on the base 1 for limiting the rotation angle of the rotating disk 2, a positioning seat 54 arranged on the base 1, and a mounting seat 55 rotatably arranged in the positioning seat 54 for mounting the driving cylinder 51; wherein the connecting plate 52 is arranged in an L shape, and the piston rod of the driving cylinder 51 is connected to the connecting plate 52 through a fisheye joint 56. By controlling the operation of the driving cylinder 51, the rotating disk 2 is driven to rotate within a range of 90 degrees, thereby realizing the reversing conveying of the box.

[0028] The limit assembly 53 includes a limit rod 531 arranged at the bottom of the rotating disk 2 and two limit members arranged on the base at an angle of 90°.

By setting two limit members at an angle of 90° on the rotating surface of the limit rod 531, the rotation angle of the rotating disk 2 is accurately limited to ensure the accuracy of the reversing conveying of the box.

[0029] When the box is being transported on the conveyor belt, it flows forward between the two clamping plates 41 through the cooperation of the guide plate 433 and the guide wheel 432. When the slot-type photoelectric sensor 6 detects that the box is in place, the conveyor belt 3 is controlled to stop working, and at the same time, the moving motor 421 is controlled to drive the moving screw 422 to rotate so that the two clamping plates 41 move toward each other to clamp the box; then the driving cylinder 51 is controlled to drive the rotating disk 2 to rotate, and under the action of the limit member, the conveyor belt is rotated 90°; then the moving motor 421 is controlled to reverse and the conveyor belt 3 is operated, so that the box can flow smoothly into the next receiving production line, completing the 90° reversing conveying of the box.

[0030] The present application limits the structure of the reversing conveying device and introduces a clamping and correction device 4 to clamp and limit the box entering the conveyor belt 3 to prevent the box from shaking during the rotation of the conveyor belt 3. At the same time, the box is centered to provide position accuracy for the next workstation; wherein, the rapid rotation of the rotating disk 2 is achieved by setting a driving cylinder 51. Compared with the traditional method of a motor combined with a gear sprocket, the equipment structure is simple and the structural cost is low.
