6. Because the swing-preventing claw 45 arranged at the lower end of the first frame body 11 is adopted, when the pushing head 5 drives the first frame body 11 to move leftwards, the fact that the speed of the rotatable accumulating trolley moving leftwards is higher than the speed of the pushing head 5 moving leftwards due to the change of the track gradient is prevented, and the rotatable accumulating trolley is prevented from being separated from the pushing head 5.

7.

The upper end of the second frame body 12 is provided with a limiting rod 34 in a manner of swinging back and forth, and the upper part of the left end of the limiting rod 34 abuts against the left side surface of the turntable base 32. The right end of the limiting rod 34 is fixedly connected with the right end of the locking rod 33. The lock lever 33 is disposed on the front and rear sides of the stopper lever 34. The left end upper portion of the lock lever 33 is provided with a first projection 331. Preferably, the left-right direction length of the first protrusion 331 matches the left-right direction length of the first through hole 311, and the front-back direction width of the first protrusion 331 matches the front-back direction width of the first through hole 311. The first protrusion 331 is aligned with the first through hole 311, and the first protrusion 331 is inserted into the first through hole 311.

The side fixedly connected with that goes up of the first track 2 that is located first support body 11 front side unlocks 22, first inclined plane 221 has been seted up respectively at both ends about unlocks 22, and first inclined plane 221 extends to both ends by the intermediate position of unlocks 22, and first inclined plane 221 extends by the upper end lower extreme of unlocks 22. An unlocking lever 36 is fixedly connected to a lower portion of the left end of the locking lever 33. Preferably, the lock release lever 36 is connected to the lock lever 33 by welding.

The unlocking rod 36 slides along the first inclined surface 221, the unlocking piece 22 presses the right end of the locking rod 33 upwards, the left end of the locking rod 33 moves downwards, the first protrusion 331 is far away from the first through hole 311, and the first rotary table 31 is unlocked. Only a specific position is required to be provided with the unlocking rod 36 with a specific length, so that the automatic unlocking and the automatic rotation of the first rotating disc 31 can be realized.

The technical scheme in the embodiment of the application at least has the following technical effects or advantages:

1. since the locking lever 33 swing-disposed at the upper end of the second housing 12, the first protrusion 331 formed at the upper portion of the left end of the locking lever 33, and the first through hole 311 formed at the first rotary disk 31 are employed, and the first protrusion 331 is fitted into the first through hole 311, it is achieved that the position of the first rotary disk 31 can be fixed when the first rotary disk 31 rotates to a designated angle.

2. Because the unlocking rod 36 fixedly connected to the lower end of the locking rod 33, the unlocking piece 22 arranged on the first track 2 at the front side of the first frame body 11 and the first inclined surface 221 arranged on the unlocking piece 22 are adopted, the unlocking rod 36 slides along the first inclined surface 221, when the rotatable stacking trolley moves to a position where a workpiece needs to be rotated, the unlocking rod 36 slides along the first inclined surface 221 and enables the right end of the locking rod 33 to move upwards, the left end of the locking rod 33 moves downwards, the first protrusion 331 is far away from the first through hole 311, and therefore automatic unlocking of the first rotary disc 31 is achieved.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
