As shown in fig. 1, the overturning and conveying mechanism provided by the embodiment of the utility model includes: a conveyance driving device 100, a movable member 200, and a rail frame 300; the movable piece 200 is in transmission connection with the conveying driving device 100; the movable member 200 is movably mounted to the rail frame 300, and the movable member 200 and/or the rail frame 300 are provided with a flip-type adapting portion 400 tending to an engaged state; in the engaged state, the conveyance driving device 100 drives the movable member 200 to flip around the flip-fitting portion 400 with respect to the rail frame 300.

When the transport driving device 100 drives the movable member 200 to move relative to the rail frame 300, first, the movable member 200 moves in the x-direction relative to the rail frame 300, so that the effect of transportation can be achieved. Secondly, when the turnover adapting part 400 is aligned and gradually engaged, the movable part 200 can turn around an axis parallel to the y direction along with the movement of the movable part 200 in the x direction, and the turnover adapting part 400 gradually disengages from the engaged state along with the movement of the movable part 200 in the x direction, so that the movable part 200 can be further turned, and thus the up-and-down turning of the movable part 200 can be realized while the movable part 200 is conveyed, and the turning angle of the movable part 200 can be 90-270 degrees. When the turnover conveying mechanism is used for turnover of the flexible piece, the movable piece 200 is preferably turned 180 degrees, so that the flexible piece can be turned while being conveyed, and the flexible piece can be bent relative to the edge of the movable piece 200, so that the flexible piece can be folded and bundled later.

In an alternative embodiment, the flip-over adaptor 400 may include a magnetic attraction device mounted to the movable member 200 or the track frame 300, and when the transport driving device 100 drives the movable member 200 to move to a magnetic force action area with respect to the track frame 300, the magnetic force may drive the flip-over adaptor 400 to be engaged, thereby driving the movable member 200 to flip. It is also possible to mount magnetic attraction means on both the movable member 200 and the rail frame 300, and to provide motive force for the flip-over adapter 400 to engage by attraction or mutual repulsion of the two magnetic attraction means.

In another alternative embodiment, a spring may be mounted on the movable member 200 or the rail frame 300, where the spring maintains an elastic power storage state when the conveying driving device 100 drives the movable member 200 to move along the x direction relative to the rail frame 300, and the elastic force of the spring drives the flip-adapting portion 400 to flip when the movable member 200 moves to the engagement area of the flip-adapting portion 400, so as to realize a cooperative action of translation and flip.

As shown in fig. 1, 2 and 3, in the embodiment of the present utility model, the roll-over adapting section 400 includes: a pivot support portion 401 provided to the movable member 200 and a branch guide portion 301 provided to the rail frame 300; the pivot support 401 is offset from the center of gravity of the moveable member 200, and the pivot support 401 tends to engage the branch guide 301 under the force of gravity of the moveable member 200.

Specifically, the gravity of the movable member 200 may cause the movable member 200 to tend to deflect, and thus the pivot support portion 401 tends to cooperate with the branch guide portion 301, not only without increasing the power source, but also utilizing the gravity of the movable member 200. When the movable member 200 can clamp or dock the workpiece, the center of gravity of the workpiece and the center of gravity of the movable member 200 should be located on the same side of the inversion axis, so that the clamping or docking of the workpiece does not affect the effect that the inversion fitting portion 400 tends to engage.

In order to facilitate the structural layout and to better utilize gravity to realize the overturning, the pivoting support 401 is deviated from the overturning axis of the movable member 200, in the initial state that the conveying driving device 100 drives the movable member 200 to move relative to the guide rail frame 300, the gravity of the movable member 200 makes the pivoting support 401 trend toward the extending direction of the branch guide 301, the pivoting support 401 moves to a position opposite to the branch guide 301 along with the movement of the movable member 200, the gravity of the movable member 200 deflects under the gravity of the movable member 200, and the pivoting support 401 is in sliding fit with the branch guide 301. After the movable member 200 translates past the branch guide 301, continued movement of the movable member 200 will pull the pivot support 401 to move in a reverse direction along the branch guide 301, gradually disengaging the engaging state on the one hand, and continuing to flip the movable member 200 about the flip axis on the other hand.

Further, the guide rail frame 300 is provided with a sliding guide portion 302, and the conveying driving device 100 is used for driving the movable member 200 to slide reciprocally along the sliding guide portion 302; the branch guide 301 is connected to the middle of the slide guide 302.

In the present embodiment, the sliding guide portion 302 extends along the x direction, and the branch guide portion 301 extends along the z direction, wherein the x direction is perpendicular to the z direction; a first relief portion 303 is provided between one end of the sliding guide portion 302 and the branch guide portion 301, and a second relief portion 304 is provided between the branch guide portion 301 and the other end of the sliding guide portion 302.

Wherein, the first abdication portion 303 and the second abdication portion 304 may be configured as arc chamfers, when the pivot support portion 401 slides from the sliding guide portion 302 into the branch guide portion 301, the pivot support portion 401 slides along the first abdication portion 303, and abdication and guiding are performed by the first abdication portion 303, thereby ensuring that the pivot support portion 401 can smoothly slide into the branch guide portion 301; when the pivot support portion 401 slides from the branch guide portion 301 into the slide guide portion 302, the pivot support portion 401 slides along the second abdication portion 304, abdication and guiding by the second abdication portion 304 are ensured, so that the pivot support portion 401 can smoothly slide to the slide guide portion 302.

In the present embodiment, the sliding guide portion 302 is configured as a lateral chute extending in the x-direction, and the branch guide portion 301 is configured as a longitudinal chute extending in the z-direction, which is easy to process and low in cost.

In addition, the pivot supporting portion 401 is configured as a pulley adapted to the branch guiding portion 301 and the sliding guiding portion 302, the axis of the pulley is parallel to and spaced from the turning axis of the movable member 200, the radially extending swing arm 202 can be mounted on the shaft 210, the pulley is rotatably connected to the swing arm 202, and the pulley slides along the transverse sliding groove and the longitudinal sliding groove, so that the sliding resistance is reduced, and the turning action jamming of the movable member 200 can be avoided.

In the initial state, the shaft rod 210 and the pivot support 401 are both matched with the sliding guide 302, and as the conveying driving device 100 drives the shaft rod 210 to move along the sliding guide 302, the pivot support 401 enters the position of the branch guide 301, the material taking part 220 turns around the axis of the shaft rod 210 under the action of gravity, and the pivot support 401 slides into the branch guide 301. After the pivot support 401 slides along the branch guide 301 to the z-direction limit position, the conveying driving device 100 continues to drive the shaft rod 210 to move along the sliding guide 302, at this time, the pivot support 401 slides reversely along the branch guide 301 and finally returns to the sliding guide 302, and in this process, the material taking part 220 continues to turn around the axis of the shaft rod 210, and finally completes 180 degrees of turning. When the conveyor drive means 100 drives the shaft 210 in a reverse direction along the slide guide 302, the reversing action is reversed, thereby reversing the take-off 220 back to the original state.
