In this embodiment, the inclined rib 16, the inclined surface 155, and the L-shaped lever 154 are provided to automatically catch the tray 2 when the tray is gripped, and to automatically release the tray 2 when the tray is pushed out. When grabbing, the tray 2 will not be clamped between the circulating lifting mechanism 1 and the production line because the protrusion 156 hooks the groove 21 of the tray 2.

The preferred bevel 155 of this embodiment is triangular. The projection 156 is rectangular.

A lifting type circulating production line comprises a circulating lifting mechanism 1, wherein the circulating lifting mechanism 1 comprises an installation frame 11, a bearing plate 13, a grabbing mechanism 15 used for grabbing a tray 2, a first telescopic structure 12 used for driving the bearing plate 13 to slide up and down on the installation frame 11, and a second telescopic structure 14 used for driving the grabbing mechanism 15 to horizontally slide on the bearing plate 13.

The sliding box 151 is horizontally slidably disposed on the bearing plate 13, and one side of the sliding box 151 close to the tray 2 is fixedly connected to the telescopic rod of the second telescopic structure 14.

The preferable conveying line of this scheme is any one of belt assembly line, board chain line, doubly fast chain.

In the scheme, the first telescopic structure 12 and the second telescopic structure 14 are preferably any one of a screw rod mechanism, a cylinder mechanism, a hydraulic cylinder mechanism and an electric telescopic mechanism.

It should be explained that the slide cassette 151 can be horizontally slidably disposed on the carrier plate 13 through a slider-and-slide mechanism. The surface of the horizontal plate 152 is slightly smaller than the inner cross section of the sliding box 151, so that the horizontal plate 152 can slide in the sliding box 151. The middle of the top surface of the sliding box 151 may be provided with a through hole between the vertical rods having a larger diameter than the L-shaped rod 154, so that the vertical rod of the L-shaped rod 154 can slide in the middle of the top surface of the sliding box 151. To facilitate the installation of the spring 153, the top surface of the slide case 151 is detachably coupled to the slide case 151, and the bottom end of the spring 153 may be welded to the horizontal plate 152. A through groove is formed in the side wall of the slide case 151 in the up-down direction to facilitate the horizontal bar of the L-shaped bar 154 to slide on the side of the slide case 151. The ramp 155 and the angled ridge 16, the projection 156 and the groove 21 can be seen in fig. 1-6. The top surface of the angled bead 16 is slightly above the lowermost end of the angled surface 155.

The first telescopic structure 12 is arranged at the bottom of the mounting frame 11, the bearing plate 13 is arranged at the top end of the first telescopic structure 12, and the bearing plate 13 can realize lifting movement in the mounting frame 11 through telescopic movement of the first telescopic structure 12; the second telescopic structure 14 is disposed on one side of the bearing plate 13, the sliding box 151 is disposed on the bearing plate 13 and fixedly connected to the second telescopic structure 14, and the sliding box 151 moves left and right on the bearing plate 13 by the telescopic movement of the second telescopic structure 14. Grooves 21 are formed on both sides of the tray 2, and the protrusions 156 can hook the grooves 21. A proximity switch may be provided on the slide case 151 or the protrusion 156. For the purpose of illustration, the two lines are divided into an upper line 32 and a lower line 33.

The working principle of the invention is described in connection with fig. 1-6:

when the invention is used, the left circulating lifting mechanism 1 is responsible for grabbing the trays 2 on the lower layer conveying line 33 onto the bearing plate 13, extending the first telescopic structure 12, lifting the bearing plate to the corresponding position of the upper layer conveying line 32, and then pushing the trays onto the upper layer conveying line 32. The circulating lifting mechanism 1 on the right side is responsible for grabbing the trays 2 on the upper-layer conveying line 32 onto the bearing plate 13, so that the first telescopic structure 12 contracts, the bearing plate descends to the position corresponding to the lower-layer conveying line 33, and then the trays are pushed onto the lower-layer conveying line 33.

The principle of the grabbing process, as shown in fig. 5-6, the second telescopic structure 14 drives the sliding box 151 to move toward the side adjacent to the tray 2, so that the inclined plane 155 contacts with the inclined rib 16, and the sliding box 151 is further pushed, and due to the blocking of the inclined rib 16, the inclined plane 155 moves along the inclined rib 16 like an inclined plane to the bottom of the sliding box, and the plurality of springs are in an extended state, and the top of the protrusion 156 is lower than the bottom of the groove 21 of the tray 2.

When the proximity switch senses that the tray moves to the protrusion 156, the second telescopic structure 14 and the first conveying line 32 are synchronously contracted, and when the inclined plane 155 is away from the inclined rib 16, the L-shaped rod 154 is lifted under the action of the plurality of springs 153, and the protrusion 156 can hook the groove 21 of the tray 2, so that the tray 2 is grabbed on the loading plate 13. When the pallet 2 is fully seated on the carrier plate 13, the movement of the second telescopic structure 14 is stopped.

The pushing out process is opposite to the grabbing process, and the second telescopic structure 14 extends to push the tray to the corresponding conveying line. When the slide cassette 151 moves to the far left, the angled rib 16 abuts the angled face 155, so that the L-shaped bar 154 descends to the far bottom of the slide cassette, with the top of the projection 156 below the bottom of the recess 21 of the pallet 2, and the pallet 2 is conveyed away by the respective conveyor line.

The control principle of the first telescopic structure 12 and the second telescopic structure 14 for controlling the grabbing mechanism 15 to grab the tray 2 is the prior art and will not be described herein.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
