Description

Technical Field

[0001] The utility model relates to the technical field of logistics assembly equipment, and particularly relates to a tray stacking mechanism with trays. Background Art

[0002] In fields such as factories, logistics, and warehousing, trays are used as carriers for goods or products.

[0031] Such as Figure 1 - Figure 2As shown in the figure, a tray stacking mechanism includes a frame body 1, a tray box conveying line 2 installed on the frame body 1, a conveying motor assembly 3 installed on the frame body 1, a lifting assembly 4 installed on the frame body 1, a slewing bearing assembly 5 installed under the frame body 1, and a tray box pin assembly 6 installed on the frame body 1. The slewing bearing assembly 5 enables the rotation of the stacking mechanism and serves as the support for the entire mechanism. The tray box conveying line 2 serves as the support for the tray box 7. The conveying motor assembly 3 drives the tray box conveying line 2 to convey the tray box 7. The lifting assembly 4 controls the up and down movement of the tray box 7. The tray box pin assembly 6 fixes the lifted tray box 7. The above components cooperate with each other to achieve the stacking and transfer of the tray box 7.

[0032] The tray box conveying line 2 installed on the frame body 1 has no position limit as long as it can safely and stably convey the tray box 7. The conveying motor assembly 3 installed on the side of the frame body 1 can only be installed on the driving wheel side of the tray box conveying line 2 and does not interfere with other components. The lifting assembly 4 can only be installed on the lower side of the frame body 1, and two groups of lifting cylinders are evenly distributed to ensure the stability of the up and down movement of the tray box 7. The slewing bearing assembly 5 can only be installed under the frame body 1, and it is necessary to ensure the stability of the entire stacking mechanism during rotation, lifting of the tray box, and conveying of the tray box. The tray box pin assembly 6 installed on the frame body 1 has no position limit as long as it can cooperate with the lifting assembly 4 to stably fix and release the tray box 7. When the various mechanisms (referring to the frame body 1, tray box conveying line 2, conveying motor assembly 3, lifting assembly 4, slewing bearing assembly 5, tray box pin assembly 6) in this case cooperate, they need to cooperate through a program.

[0033] The frame body 1 includes a frame welded by rectangular tubes, and a slewing detection switch, a guide rail, and a height detection switch are provided on the frame.

[0034] The tray box conveying line 2 is installed on the frame body 1, that is Figure 2 on the upper side.

[0035] The conveying motor assembly 3 is installed on the side of the frame body 1, that is Figure 2 on the right side.

[0036] The lifting assembly 4 is installed on the lower side of the frame body, that is Figure 1 on the lower side.

[0037] The slewing bearing assembly 5 is installed under the frame body 1, that is Figure 1 on the lower side.

[0038] The tray box pin assembly 6 is installed on the frame body 1, that is Figure 1 on the upper side.

[0039] In the practical process, without excluding other possible positional relationships of the components, the tray box conveying line 2, conveying motor assembly 3, lifting assembly 4, slewing bearing assembly 5, and tray box pin assembly 6 installed on the frame body 1 can achieve the stacking and transfer of the tray box 7.

[0040] The stacking and transfer of the above-mentioned cassette 7 are as follows:

[0041] In the initial state, the rotation detection switch on the frame 1 detects and adjusts the guide rail to align with the existing cassette feeding station guide rail through the slewing support assembly 5. The lifting cylinder of the lifting assembly 4 retracts, and the pin of the cassette pin assembly 6 retracts;

[0042] Feeding: After receiving the signal that the cassette 7 enters, the conveying motor assembly 3 starts, and the cassette conveying line 2 drives the cassette 7 into the internal part of the stacking mechanism. After the cassette detection switch on the cassette conveying line 2 detects that the cassette 7 is in place, the conveying motor assembly 3 stops;

[0043] Stacking: The lifting cylinder of the lifting assembly 4 lifts the cassette 7 to the top high position. After the cassette 7 is in place, the pin of the cassette pin assembly 6 extends to fix the cassette 7. The lifting assembly 4 returns to the initial position and waits for the next cassette. After repeating a round of feeding steps, the lifting cylinder of the lifting assembly 4 lifts the cassette 7 to the lifting middle position. At this time, the just-entered cassette 7 lifts the previously entered cassette 7 to a certain height, disengaging it from the pin. The pin of the cassette pin assembly 6 retracts, and the lifting cylinder of the lifting assembly 4 continues to lift the cassette 7 to the top high position. The pin of the cassette pin assembly 6 extends to fix the cassette 7, completing the stacking action, and the lifting assembly 4 returns to the initial position;

[0044] Discharging: After the pin of the pin assembly 6 retracts, the lifting cylinder of the lifting assembly 4 returns to the initial position, and the cassette 7 returns to the cassette conveying line 2 again. At this time, the slewing support assembly 5 starts to rotate. The rotation detection switch on the frame 1 detects and adjusts the guide rail to align with the existing cassette discharging station guide rail through the slewing support assembly 5. The conveying motor assembly 3 starts, and the cassette conveying line 2 takes the cassette 7 out of the stacking mechanism.

[0045] In the above steps, the "lifting middle position" and "top high position" when the lifting cylinder of the lifting assembly 4 rises are detected by the height detection switch on the frame 1. The extension and retraction of the pin of the cassette pin assembly 6 are detected by the magnetic sensor switch on the telescopic cylinder. Each component cooperates with the detection switch to ensure the stability and reliability of the system.

[0046] In the practical process, a tray-type stacking mechanism is installed in a specific application scenario. The rotation of the stacking mechanism is realized through the slewing support assembly, which also serves as the support of the entire mechanism. The cassette conveying line serves as the support of the cassette. The conveying motor assembly drives the cassette conveying line to convey the cassette. The lifting assembly controls the up and down lifting of the cassette. The cassette pin assembly fixes the lifted cassette. The above components cooperate with each other to achieve the stacking and transfer of the cassette.
