DETAILED DESCRIPTION

[0024] Example one

[0025] For example Figures 1-4As shown, the reciprocating product grabbing device provided in the embodiment comprises a mounting plate 1, a limiting track 6, a rack 7 and a plurality of jaw mechanisms.

[0026] The mounting plate 1 is installed at the upper end of the rack 7, and a linear driving mechanism 8 for driving the mounting plate 1 to lift is installed on the rack 7. It is necessary to supplement that the linear driving mechanism 8 is one of a pneumatic cylinder, a hydraulic cylinder or an electric push rod. A transmission belt 2 is installed below the mounting plate 1, and a power assembly for driving the transmission belt 2 to move is arranged on the mounting plate 1. The power assembly comprises a servo motor 4 and two transmission rollers 3. Both of the transmission rollers 3 are rotatably installed on the mounting plate 1, the transmission belt 2 is sleeved on the two transmission rollers 3, and the servo motor 4 is arranged on the mounting plate 1 and its output shaft is connected with the rotating shaft of the transmission roller 3.

[0027] A plurality of jaw mechanisms are equidistantly installed on the outer periphery of the transmission belt 2. The jaw mechanism comprises a cylinder 5, a spring 14, a movable shaft 17 and a plurality of clamping assemblies. The fixed plate 11 is connected between the cylinder 5 and the transmission belt 2. The movable shaft 17 movably penetrates through the cylinder 5. The inner wall of the cylinder 5 is provided with a fixed ring 19. The movable shaft 17 is connected with a movable ring 18. The spring 14 is sleeved and installed on the movable shaft 17. The spring 14 is located between the movable ring 18 and the fixed ring 19. The clamping assembly is provided with at least three groups. The plurality of clamping assemblies are installed on the lower end of the cylinder 5 in an annular array. The clamping assembly comprises a clamping frame 12, a rotating frame 13 and a rotating rod 16. The rotating frame 13 is connected with the cylinder 5. The clamping frame 12 is rotatably installed on the rotating frame 13. The clamping frame 12 is in a "C" shape. The bottom end of the clamping frame 12 is provided with a rubber clamping block 15. The arrangement of the rubber clamping block 15 can reduce noise and buffer. One end of the rotating rod 16 is hinged with the end portion of the clamping frame 12, and the other end thereof is hinged with the movable shaft 17.

[0028] The limiting track 6 is connected with the mounting plate 1. The limiting track 6 is arranged for half a circle around the outer periphery of the transmission belt 2. One end of the limiting track 6 is upwardly raised.

[0029] Specifically, when the tea can on the work station A is conveyed to the work station B, the work station A and the work station B in the technical scheme are respectively the lower two ends of the transmission belt 2. The work station B is arranged at the upwardly raised position adjacent to the limiting track 6. The tea can is placed at the position directly below the work station A. When the jaw mechanism moves to the position of the work station A, the movable shaft 17 is just separated from the limiting track 6 at this time. The compressed spring 14 is quickly reset and drives the movable shaft 17 to move upward. Under the cooperation of the rotating rod 16, the clamping frame 12 is driven to turn inward, thereby realizing the clamping work of the tea can. With the continuous movement of the transmission belt 2, when the movable shaft 17 starts to contact with the raised position of the limiting track 6, the movable shaft 17 gradually moves downward. That is, the plurality of clamping frames 12 are synchronously turned outward, thereby releasing the clamping of the tea can. At this time, the tea can falls into the work station B, thereby realizing the whole conveying process.
