[0003] In the conventional tray feeding device, the following technical problems are generally present: 1. The equipment needs to be stopped and waited when the tray is loaded or unloaded on the material bin; 2. The material bin needs to be regularly and quantitatively loaded and unloaded; 3. The next tray cannot be supplied to the processing station until the previous tray is recycled to the material bin. INVENTION CONTENTS

[0004] The utility model aims to provide a multi -position tray classification, warehouse and feeding device to solve the technical problems in the background art.

[0005] The multi -position tray classification, warehouse and feeding device comprises a base plate, a material seat and a moving module installed on the base plate, a plurality of storage units arranged beside the moving module installed on the material seat, the storage units are used for stacking the trays, the moving module is drivingly connected with a moving frame, a taking and placing module is installed on the moving frame, the moving module is used for driving the moving frame to move the taking and placing module to each storage unit, the taking and placing module is used for taking out the tray on the storage unit and feeding the tray to the processing station, and is used for sending the tray used on the processing station back to another storage unit.

[0006] According to the technical scheme, since a plurality of storage units are arranged, the moving module can drive the moving frame to move the taking and placing module to each storage unit, that is, the taking and placing module can take out the tray on the storage unit and feed the tray to the processing station, and send the tray used on the processing station back to another storage unit, therefore, when the taking and placing module takes out all the trays on a storage unit or sends the tray used on the processing station back to the storage unit, the moving module can drive the moving frame to move the taking and placing module to another storage unit, so as to take out the tray on the other storage unit and feed the tray to the processing station, and send the tray used on the processing station back to the other storage unit for stacking, during which, the operator or the mechanical hand can supplement the tray to the empty storage unit or take out the stacked tray in the storage unit; so that the utility model has the following beneficial effects:

[0007] 1. When replenishing material trays to empty storage units or removing stacked material trays from storage units, the equipment does not need to stop and wait.

[0008] 2. Since there are several storage units, the material trays can be placed in the storage units only before all the material trays in the storage units have been taken out and the material trays in the storage units have been filled with the finished products. This eliminates the need to take out and put out material trays at fixed times and in fixed quantities.

[0009] 3. Because it is equipped with several storage units, it is possible to classify and store the material trays in the processing station into various storage units according to the different processing conditions of the processing station.

[0010] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0011] In some embodiments, the mobile frame is equipped with at least two pick-and-place modules, such that when one pick-and-place module removes the material tray from the storage unit and supplies it to the processing station, the other pick-and-place module is used to return the material tray used by the processing station to another storage unit.

[0012] According to the aforementioned technical solution, it is possible to eliminate the need to wait for the previous material tray to be returned to the hopper before it can be retrieved from another storage unit, thereby improving the efficiency of loading and unloading.

[0013] In some implementations, the mobile module is independently driven connected to at least two mobile frames;

[0014] According to the technical solution, during the process of the mobile module driving one of the mobile frames to move the pick-and-place module to transport the material tray on the processing station and put it back into the storage unit, the mobile module simultaneously drives another mobile frame to move the pick-and-place module to transport the material tray in another storage unit to the processing station. Therefore, it is possible to remove the next material tray from another storage unit and supply it to the processing station without waiting for the previous material tray to be returned to the hopper.

[0015] In some embodiments, the storage unit is equipped with an opening and closing cylinder, which drives trays located at the bottom of the storage unit that can be brought together or opened. The trays are used to hide on both sides of the bottom of the material tray stacked at the bottom. The pick-and-place module includes a conveyor line and a lifting module. The conveyor line is used to support the bottom sides of the material tray, and one end of the conveyor line extends to the bottom of the storage unit. The lifting module is driven to connect a lifting top plate located below the storage unit and the conveyor line. The lifting top plate is used to lift the material tray on the conveyor line into the storage unit and to place the material tray in the storage unit onto the conveyor line.

[0016] According to the described technical solution, the present invention achieves the following beneficial effects:

[0017] 1. The lifting module drives the lifting plate to rise, lifting the material trays stacked on the pallets. Then, the opening and closing cylinder drives the pallets to open apart, moving them away from the bottom sides of the material trays. After that, the lifting module drives the lifting plate to descend until the lowest stacked material tray is below the pallet. Then, the opening and closing cylinder drives the pallets to close together, moving them to the bottom sides of the second lowest stacked material tray. After that, the lifting module drives the lifting plate to continue descending until it is below the conveyor line, placing the material trays on the lifting plate onto the conveyor line. The conveyor line then transports the material trays to the processing station. Thus, the material trays in the storage unit are removed and transported to the processing station.

[0018] 2. The conveyor line transports the material trays from the processing station to the top of the lifting platform. Then, the lifting module drives the lifting platform to rise, lifting the material trays on the conveyor line to below the material trays supported by the pallets. Next, the opening and closing cylinders drive the pallets to open apart, moving them away from the bottom sides of the material trays, allowing the material trays on the pallets to stack on the material trays on the lifting platform. The lifting module then drives the lifting platform to continue rising until the material trays at the lowest position are higher than the pallets. The opening and closing cylinders then drive the pallets to close together, moving them to the bottom sides of the material trays at the lowest position. Finally, the lifting module drives the lifting platform to descend and reset. At this point, the stacked material trays are placed on the pallets. Therefore, the material trays in the processing station are transported and stored in the storage unit.

[0019] In some embodiments, the bottom sides of the material tray are provided with clearance openings for the tray to extend into.

[0020] According to the technical solution, when the opening and closing cylinders drive the pallets to move closer together, the pallets can stably support the stacked material trays.

[0021] In some embodiments, corner posts are installed at the four corners of the storage unit, and the outer corners of the stacked material trays on the storage unit slide inside the corner posts so that the stacked material trays can be raised and lowered vertically.

[0022] According to the aforementioned technical solution, the stacked material trays are prevented from tilting and collapsing during lifting.

[0023] In some implementations, the top of the corner post is an opening to allow stacked material trays to be removed or placed in from the top of the corner post;

[0024] According to the technical solution, when the pick-and-place module removes or stacks material trays on the pallet, the operator or robot can replenish material trays or remove stacked material trays based on the storage unit without pausing the equipment.

[0025] In some embodiments, the angle folding column is installed with a position sensor for sensing the height and number of stacked material trays;

[0026] According to the technical scheme, each storage unit can determine whether the stacked material trays are full or the material trays are taken out according to the height of the stacked material trays, so as to give a signal to the moving module to drive the moving frame to move the taking and placing module to another storage unit.
