Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a non-powered lifting conveying device. Background Art

[0002] Currently in the automobile manufacturing industry, there are two main ways to transport bumpers on bumper assembly lines. One is to rely on gravity sliding chutes for transportation.

The other is to use a motor to drive the belt to rotate. However, when using a motor to drive the belt to rotate, each chute requires two 0.5KW motors, which consumes a lot of electricity. Both of the above methods cannot meet the needs of users. Utility Model Content

The push rod 44 is connected to the second platform assembly 42. When the second platform assembly 42 drives the push rod 44 to rotate upward and return to the original position, the push rod 44 abuts against the stopper 11 to move the stopper 11 from the blocking position 111 to the release position 112, thereby separating the stopper 11 from the pallet 200, so that the pallet 200 can move smoothly from the first discharge port 212 to the second platform assembly 42.

[0048] In this embodiment, a blocking structure may also be provided at the second discharge port 222 for abutting against the tray 200 to limit the tray 200 from moving from the second discharge port 222 to the first platform assembly 34 , thereby preventing the tray 200 from directly sliding off the second discharge port 222 when the first platform assembly 34 is not abutting against the second discharge port 222 .

[0049] like Figure 7 and Figure 8 As shown, in one embodiment, the second lifting mechanism 4 also includes a tension spring 45, one end of the tension spring 45 is connected to the frame 1, and the other end of the tension spring 45 is connected to the stopper 11, and the push rod 44 is slidably connected to the second platform assembly 42, and the push rod 44 has an extended position 441 and a retracted position 442. When the push rod 44 is in the extended position 441, the push rod 44 drives the stopper 11 to move from the blocking position 111 to the release position 112; a baffle 443 is provided at one end of the push rod 44 away from the first discharge port 212, and the baffle 443 is used to abut against the pallet 200 so that the pallet 200 can drive the push rod 44 to move from the extended position 441 to the retracted position 442 through the baffle 443. When the push rod 44 is in the retracted position 442, the push rod 44 is separated from the stopper 11 so that the tension spring 45 can drive the stopper 11 to move from the release position 112 to the blocking position 111; specifically, the push rod 44 and the first platform assembly 42 are connected. The assembly 34 is slidably connected. When the first platform assembly 34 rotates downward, the push rod 44 is in the extended position 441 due to gravity. When the second platform assembly 42 rotates from the second feed port 221 to the first discharge port 212, the push rod 44 in the extended position 441 can abut against the block 11, so that the block 11 moves from the blocking position 111 to the release position 112, thereby separating the block 11 from the pallet 200, so that the pallet 200 can move from the first discharge port 212 to the second platform assembly 42. At this time, the tension spring 45 is in a stretched state. When the pallet 200 moves to the second platform assembly 42, it abuts against the baffle 443 on the push rod 44. The baffle 443 drives the push rod 44 to move from the extended position 441 to the retracted position 442. The push rod 44 is separated from the block 11, and the tension spring 45 is reset to drive the block 11 to move from the release position 112 to the blocking position 111.

Specifically, in order to ensure that the tray 200 can slide stably on the first smooth bar 213 and the second smooth bar 223, the number of the first smooth bar 213 and the second smooth bar 223 is multiple. , multiple first smooth bars 213 and multiple second smooth bars 223 are snap-connected with the frame 1 for easy installation and removal, and multiple first smooth bars 213 are arranged at intervals on the frame 1 so that multiple first smooth bars 213 can respectively contact with the bottom of the tray 200 at intervals to ensure the stability of the tray 200 sliding from the first feed port 211 to the first discharge port 212 under the action of gravity; multiple second smooth bars 223 are arranged at intervals on the frame 1 so that multiple second smooth bars 223 can respectively contact with the bottom of the tray 200 at intervals to ensure the stability of the tray 200 sliding from the second feed port 221 to the second discharge port 222 under the action of gravity. In this embodiment, the first smooth bars 213 and the second smooth bars 223 are existing structures, and their specific structures and functions are not described in this embodiment.
