[0026] The specific implementation modes of the present invention are described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only used to illustrate the present invention in detail and do not limit the scope of the present invention in any way.

[0027] Embodiment 1: A tray shifting and changing device, see Figures 1 to 6 , including at least two transverse conveyor belts 1 and at least one toggle assembly 2, the toggle assembly 2 is arranged above the transverse conveyor belt 1 and cross-arranged with the transverse conveyor belt. In this embodiment, four parallel transverse conveyor belts are arranged, the two on the right are forward conveyor belts that convey the trays 3 from right to left, and the two on the left are reverse conveyor belts that convey the trays 3 from left to right. For the convenience of description above, the right side is not absolutely defined as forward and the left side as reverse, and it can be reversed according to actual needs.

[0028] Stoppers 11 are arranged at intervals on the transverse conveyor belt 1, and the distance between two adjacent stoppers 11 is equal to or slightly greater than the length of the tray 3. The transverse conveyor belt 1 is arranged on a mounting frame 12, and the mounting frame 12 has a transition plate 13 and a limit stop bar 14. The transition plate 13 is located at the bottom of the mounting frame 12, and a conveyor belt receiving groove 15 is arranged on the transition plate 13. The transverse conveyor belt 1 is arranged in the conveyor belt receiving groove 15. The two ends of the transverse conveyor belt 1 are driven by rollers, and the rotating shaft is installed at the two ends of the conveyor belt receiving groove 15. The height of the transverse conveyor belt 1 is the same as that of the transition plate 13. The tray 3 moves on the transition plate 13 under the push of the stoppers 11.

[0029] The limit stop bars 14 are arranged on both sides of each transverse conveyor belt 1, and the distance between two adjacent limit stop bars 14 is equal to or slightly larger than the width of the tray. The limit stop bars 14 extend to the toggle assembly 2, and there is no limit stop bar below the wave assembly 2 to provide space for the longitudinal displacement of the tray 3.

[0030] A conveyor belt drive motor 16 is provided at the right side of the bottom of the mounting frame 12, and the conveyor belt drive motor 16 is connected to a drive shaft 17. One end of the drive shaft 17 is connected to the forward conveyor belt on the right side through a forward connecting belt 18, and the other end of the drive shaft 17 is meshed with a reversing gear 19, and the reversing gear 19 is connected to the reverse conveyor belt through a reverse connecting belt 110. The driving roller shafts of the two forward conveyor belts on the right side are coaxially connected and move synchronously through a connecting rod. Similarly, the driving roller shafts of the two reverse conveyor belts on the left side are also coaxially connected and move synchronously through a connecting rod. Both the forward connecting belt 18 and the reverse connecting belt 110 are synchronous belts, which are respectively connected to the driving connecting rod shaft of the forward conveyor belt and the driving connecting rod shaft of the reverse conveyor belt and move synchronously in opposite directions.

[0031] Conveyor belt support wheels 111 are provided at both sides of the conveyor belt at the bottom of the mounting frame 12. The conveyor belt support wheels 111 are fixed by a gate-shaped frame 113 and clamped on both sides of the bottom of the transverse conveyor belt 1. A circular protrusion 112 is provided on the inner side of the conveyor belt support wheel 111. The transverse conveyor belt 1 is supported by the circular protrusion, and the side of the transverse conveyor belt 1 is located on the inner side of the conveyor belt support wheel 111. The conveyor belt support wheel 111 not only provides support for the transverse conveyor belt to prevent the natural falling caused by the lack of support at the bottom due to its excessive length, but also the clamping on both sides can ensure the stability of the conveyor belt.

[0032] The toggle assembly 2 includes a longitudinally moving annular toggle belt 21 and a toggle block 22 arranged on the toggle belt, which is used to realize the displacement of the tray 3 between the forward conveyor belt and the reverse conveyor belt. Driving rollers 23 are arranged at both ends of the inner side of the annular toggle belt 21, and the driving rollers 23 are arranged with external teeth. The inner side of the annular toggle belt 21 is provided with internal teeth meshing with the external teeth to ensure stability. Two driving rollers 23 are installed on both sides of the mounting frame 12. The adjacent driving rollers 23 of the two toggle assemblies 2 are connected by a coupling and a coaxial expansion sleeve to make them move synchronously. The toggle block 22 is provided with a groove matching the edge of the tray 3 so that the toggle block 22 can fit with the tray 3 to ensure the stability of the tray 3 when it is displaced and play a limiting function when the tray 3 moves horizontally.

[0033] The method for changing the direction of a tray using the above tray shifting and changing direction device comprises the following steps: Figure 7 ,

[0034] S1: The two teams of trays on the forward conveyor belt move to the left to reach the longitudinal transfer position. Figure 7 a;

[0035] S2: The first row of pallets at the head of the team moves one pallet position toward the reverse conveyor belt, such as Figure 7 b;

[0036] S3: The forward conveyor belt continues to move forward one box-carrying position, and the reverse conveyor belt moves backward one box-carrying position. Figure 7 c;

[0037] S4: The first row of three trays in the longitudinal transfer position moves one tray position to the reverse conveyor belt, such as Figure 7 d;

[0038] S5: Repeat S3 to S4 to transfer the trays between the forward and reverse conveyor belts, as follows:

[0039] S51: After S4, the forward conveyor belt continues to move forward one box-carrying position, and the reverse conveyor belt moves backward one box-carrying position, such as Figure 7 e;

[0040] S52: The two rows of four trays at the head of the team entering the longitudinal transfer position move one tray position toward the reverse conveyor belt, such as Figure 7 f;

[0041] S53: The forward conveyor belt continues to move forward one box-carrying position, and the reverse conveyor belt moves backward one box-carrying position. Figure 7 g;

[0042] S52: The two rows of four trays at the head of the team entering the longitudinal transfer position move one tray position toward the reverse conveyor belt, such as Figure 7 h;

[0043] The toggle assembly 2 moves the two rows of trays at the head of the queue into the longitudinal transfer position one tray position toward the reverse conveyor belt each time, completing the transfer of the trays on the forward conveyor belt to the reverse conveyor belt. It is foreseeable that if the forward conveyor belt and the reverse conveyor belt are changed to three each, three toggle assemblies 2 need to be provided, and the method of moving one tray position toward the reverse conveyor belt each time is still adopted, but three rows of trays need to be moved simultaneously, and so on.

[0044] The tray shifting device completes the transfer of the tray between the forward conveyor belt and the reverse conveyor belt, places the first category of food in the forward transported tray, and then transfers the tray to the reverse conveyor belt to load the second category of food, thereby placing different types of food in the same tray.

[0045] The utility model is described in detail above with reference to the accompanying drawings and embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the utility model, the specific parameters in the above embodiments may be changed to form a plurality of specific embodiments, which are all within the common variation range of the utility model and will not be described in detail here.
