The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0050] like Figures 1 to 17The material tray 1 loading and unloading device shown includes:

[0051] The material tray 1 includes a plurality of material placement slots 11 for placing bottles, a support rod 12 protruding from one end surface of the material tray 1, a positioning pin 13 sleeved on the support rod 12, and at least two groups of clamping grooves 14 opened on the edge of the material tray 1. Figure 1 , Figure 2 As shown, when multiple layers of material trays 1 are stacked, the support rod 12 is used to support the upper material tray 1, and the positions of the material trays 1 are accurately positioned by the clamping between the positioning pins 13. At the same time, when grabbing the material tray 1, the clamping claw is extended into the clamping groove 14 to carry the material tray 1. It should be pointed out here that the height of the support rod 12 can be set according to the height of the material inside the material placement slot 11. It should be pointed out here that the material of the material tray 1 needs to have a certain hardness, which can be stainless steel, aluminum alloy, PP or HDPE, or other materials that can bear materials and have a certain hardness.

[0052] The cache mechanism 2 includes a first cache rack 21 for storing the material tray 1, and a first clamping assembly 22 for clamping the clamping groove 14. The first cache rack 21 also has a first output port 21a1, and the first clamping assembly 22 is arranged at the first output port 21a1. Figure 3 , Figure 4 , Figure 5 As shown, a plurality of material trays 1 can be stored in the first buffer rack 21, and the first clamping assembly 22 clamps the material tray 1 at the bottom layer by extending into the clamping groove 14, and outputs the material tray 1 at the bottom layer in sequence through the first output port 21a1 during operation. It should be pointed out here that the first clamping assembly 22 has many forms, and can be a clamp driven by pneumatics, or can be driven by electric, hydraulic, etc.

[0053] The transfer mechanism 3 includes a frame 31, a longitudinal transfer component 32 slidably connected to the frame 31 and moving toward or away from the first output port 21a1, a second buffer rack 33 for storing the material tray 1, and an output component 35 for transferring the second buffer rack 33, the second buffer rack 33 has a second input port 33a1 and a second output port 33a2, and the longitudinal transfer component 32 can pass through the second input port 33a1 and the second output port 33a2. Figure 3 , Figure 4 , Fig.13 , Fig.15As shown, the longitudinal transfer component 32 can slide relatively through the second output port 33a2 and the second input port 33a1. The longitudinal transfer component 32 is used to receive the material tray 1 delivered from the first output port 21a1 on the one hand, and is used to receive the material tray 1 delivered from the loading and unloading mechanism 4 on the other hand. The second cache rack 33 is used to cache multiple material trays 1 delivered from the loading and unloading mechanism 4. When the material trays 1 in the second cache rack 33 are full, the output component 35 moves out the second cache rack 33 filled with material trays 1 for unloading.

[0054] The loading and unloading mechanism 4 includes a lifting assembly 41 fixed on the frame 31 for lifting the material tray 1, and a lateral transfer assembly 42 for conveying the material tray 1 back and forth between the first output port 21a1 and the lifting assembly 41. Figure 3 , Figure 4 , Figure 5 , Fig. 9 As shown, the material tray 1 output from the first output port 21a1 is received by the longitudinal transfer component 32, and is transferred to the transverse transfer component 42, and then the material tray 1 is transported to the lifting component 41 by moving the transverse transfer component 42, and the material tray 1 is first aligned with the lifting component 41 by lowering the lifting component 41, and then the lifting component 41 is raised to receive the material tray 1, and when the operating station empties or fills the material tray 1 on the lifting component 41, the transverse transfer component 42 transfers the material tray 1 to the first output port 21a1. It should be pointed out here that there are many forms of control of the transverse transfer component 42 and the lifting component 41, which can be controlled by a motor, or by a cylinder or hydraulic pressure.

[0055] The first output port 21a1, the second input port 33a1 and the second output port 33a2 are coaxially arranged. Figure 3 , Figure 4 , Figure 5 , Fig.15 As shown, by arranging the first output port 21a1, the second input port 33a1 and the second output port 33a2 to be coaxial, the smoothness of transmission between the buffer mechanism 2, the pick-up and delivery mechanism 3 and the loading and unloading mechanism 4 is improved, the transmission resistance and time are reduced, and the overall production efficiency is improved.

[0056] like Figure 3 , Figure 4As shown, in the specific working process of the present invention, firstly, a plurality of material trays 1 are placed into the first cache rack 21, and the material tray 1 at the bottom layer in the first cache rack is clamped by the first clamping assembly 22, and the lateral transfer assembly 42 is moved to the first output port 21a1, and then the longitudinal transfer assembly 32 is driven to the first output port 21a1 to dock the material tray 1 at the bottom layer, and the first clamping assembly 22 is released, and the longitudinal transfer assembly 32 drives all the material trays 1 in the first cache rack 21 to move downward, and after moving to the height of a material tray 1, the first clamping assembly 22 clamps the material tray 1 at the first output port 21a1; the lifting assembly 41 is lowered, and the lateral transfer assembly 4 ... lateral transfer assembly 32 is driven to the first output port 21a1 to dock the material tray 1 at the bottom layer, and the lateral transfer assembly 32 is driven to the first output port 21a1 to dock the material tray 1 at the bottom layer, and the lateral transfer assembly 32 is driven to dock the material tray 1 at the bottom layer, and the lateral transfer assembly 32 is driven to dock the material tray 1 at the bottom layer, and the lateral transfer assembly 32 is driven to dock the material tray 1 at the bottom layer, and the lateral transfer assembly 32 is driven to dock the The transfer assembly 42 clamps the material tray 1 on the longitudinal transfer assembly 32 to the lifting assembly 41, and the lifting assembly 41 rises to receive the material tray 1. Other external stations clamp the materials on the material tray 1, or clamp the materials onto the material tray 1. When the materials on the material tray 1 are emptied or filled, the transverse transfer assembly 42 clamps the material tray 1, and then the lifting assembly 41 is lowered. The transverse transfer assembly 42 transfers the material tray 1 to the first output port 21a1; the longitudinal transfer assembly 32 rises to receive the material tray 1, and docks the material tray 1 at the bottom of the first cache shelf 21 again. The first clamping assembly 22 opens, and the longitudinal transfer assembly 32 drives the material tray 1 to move down. The material tray 1 is transferred in this cycle until the material tray 1 in the second cache shelf 33 is full, and the output assembly 35 pushes out the second cache shelf 33 to unload the material tray 1 in the second cache shelf 33.

[0057] The present invention can realize continuous loading and unloading operation of the material tray 1 through the multi-disc storage function of the first cache rack 21 and the second cache rack 33. This design ensures that when one material tray 1 is loading and unloading, the other material tray 1 is already in a standby state, thereby significantly reducing the waiting time and improving the continuous operation capacity and overall production efficiency of the production line. At the same time, the entire device integrates multiple automation mechanisms such as caching, picking up and delivering, loading and unloading, etc., realizing the full automation from storage and transportation to loading and unloading of the material tray 1, which not only reduces the burden of manual operation, but also reduces the possibility of human error, further improving the stability and reliability of the production process, and then through the cooperation of the clamping groove 14 on the material tray 1 and the first clamping component 22, the cooperation of the longitudinal transfer component 32 and the second cache rack 33, etc., the entire device is more flexible and smooth during operation. At the same time, the coaxial arrangement of the first output port 21a1, the second input port 33a1 and the second output port 33a2 also optimizes the flow path of the material tray 1 in the device, and improves the flow efficiency and production efficiency.

[0058] like Figure 5 , Figure 8As shown, the first cache rack 21 includes a first bottom plate 21a, a plurality of first baffle assemblies 21b perpendicular to the first bottom plate 21a, a first output port 21a1 is opened on the first bottom plate 21a, the area of ​​the first output port 21a1 is slightly larger than the area of ​​the material tray 1, and the first output port 21a1 is also provided with a first in-position detection assembly 23. The first baffle assembly 21b is used to return the material tray 1 to its original position, so that the upper and lower multi-layer material trays 1 are aligned to prevent the material trays 1 from offsetting. The design that the area of ​​the first output port 21a1 is slightly larger than the area of ​​the material tray 1 ensures that the material tray 1 can pass smoothly during the output process, avoids the problem of jamming or damage caused by size mismatch, and ensures the smooth transition of the material tray 1 from the cache mechanism 2 to the pick-up mechanism 3 or the loading and unloading mechanism 4. The first in-place detection component 23 added at the first output port 21a1 can monitor in real time whether the material tray 1 has reached the specified position to achieve precise control and automated operation. At the same time, through in-place detection, the system can accurately judge the state of the material tray 1, thereby triggering subsequent loading and unloading or transfer operations, thereby improving the accuracy and reliability of automated control.

[0059] like Figure 7 , Figure 8 As shown, in order to make the first baffle assembly 21b return the material tray 1 more accurately, the first baffle assembly 21b includes a first fixed guide plate 21b1 fixedly arranged, and a first movable guide plate 21b2 movably connected to the first fixed guide plate 21b1. The first fixed guide plate 21b1 and the first movable guide plate 21b2 are configured so that the angle formed when the two are reset is the same as the edge angle of the material tray 1, and both ends of the first fixed guide plate 21b1 and the first movable guide plate 21b2 have a bend 21b3. The first fixed guide plate 21b1 and the first movable guide plate 21b2 are configured so that the angle formed when the two are reset is the same as the edge angle of the material tray 1, ensuring that the material tray 1 can be accurately guided and positioned when entering, exiting or passing through the baffle assembly, reducing the risk of the material tray 1 being blocked or damaged due to angle deviation. The bends 21b3 arranged at both ends of the first fixed guide plate 21b1 and the first movable guide plate 21b2 can guide the material tray 1 that is not accurately returned.

[0060] In order to make the clamping assembly of the material tray 1 more stable, Figure 5 , Figure 6As shown, the first clamping assembly 22 includes two groups of first clamping jaws 22a that are relatively arranged and can be relatively close to or away from each other in the direction of the material tray 1, a first driving member 22b for driving the first clamping jaws 22a, and a first guide assembly 22c fixedly connected to the first clamping jaws 22a. The first clamping jaws 22a include clamping jaws 22a1 that can be inserted into the clamping groove 14 and fixed jaws 22a2 fixed above the material tray 1. The two groups of first clamping jaws 22a that are relatively arranged can be relatively close to or away from each other under the drive of the first driving member 22b, so as to achieve accurate clamping of the material tray 1. The clamping jaws 22a1 can be inserted into the clamping groove 14, which increases the stability and accuracy of the clamping and prevents the material tray 1 from shifting or falling off during the transmission or processing process. The material tray 1 is clamped between the clamping jaws 22a1 and the fixed jaws 22a2, and the material tray 1 can be prevented from falling off during the transfer process by fixing the two. It should be pointed out here that the first driving member 22b and the second driving member 42b, the longitudinal driving member 32c, the transverse driving member 42d, the output driving member 35b, and the lifting driving member 41b described below have many forms, which can be motor-driven, hydraulically driven, pneumatically driven, magnetically driven, or other forms of driving.

[0061] In some embodiments of the present invention, Fig.13 , Fig.14 As shown, the longitudinal transfer assembly 32 includes a longitudinal support plate 32a for receiving the material tray 1, a linear guide assembly 32b connected between the frame 31 and the longitudinal support plate 32a, and a longitudinal driving member 32c for driving the longitudinal support plate 32a to slide. The longitudinal support plate 32a also has a positioning column 32a1. The linear guide assembly 32b ensures the linear movement of the longitudinal support plate 32a on the frame 31, reduces the offset and shaking during the movement, and ensures the stability and accuracy of the material tray 1 during the transfer process. The setting of the positioning column 32a1 further enhances the positioning accuracy of the material tray 1 on the longitudinal support plate 32a, which can cooperate with the positioning hole or specific structure on the material tray 1 to ensure that the position of the material tray 1 during the transfer process is accurate. The setting of the longitudinal transfer assembly 32 can complete two tasks at the same time, one is to move the material tray 1 out of the first cache rack 21, and the other is to receive the material tray 1 in the second cache rack 33. It should be pointed out here that the linear guide assembly 32b has many forms, which can be a linear guide or a linear bearing, an oil-free bushing or a ball screw, or a guide shaft and a support and other forms.

[0062] In order to make the material tray 1 delivered by the loading and unloading mechanism 4 be stacked more accurately, Fig.15 , Fig.16As shown, the second cache rack 33 includes a second base plate 33a, a plurality of second baffle assemblies 33b perpendicular to the second base plate 33a, a second output port 33a2 is opened on the second base plate 33a, the second base plate 33a also has a limit block 33c adapted to the edge of the material tray 1, the second base plate 33a is configured to place the material tray 1, and the second input port 33a1 also has a second in-place detection assembly 34, wherein the second baffle assembly 33b also includes a second fixed guide plate 33b1 fixedly connected to the second base plate 33a, and a second movable guide plate 33b2 rotatably connected to the second fixed guide plate 33b1, the second fixed guide plate 33b1 and the second movable guide plate 33b2 are configured so that the angle formed when the two are reset is the same as the edge angle of the material tray 1, and both ends of the second fixed guide plate 33b1 and the second movable guide plate 33b2 have a bending portion 21b3. By setting a stopper 33c adapted to the edge of the material tray 1, it can be ensured that the material tray 1 can be accurately aligned when placed, preventing the material tray 1 from sliding or offsetting in the cache rack. The second bottom plate 33a can also be used to place the material tray 1, so that the material tray 1 can be placed in the second cache rack 33 without falling off after leaving the longitudinal transfer component 32. The second baffle assembly 33b is a combination of the second fixed guide plate 33b1 and the second movable guide plate 33b2. When the two are reset, the angle formed is the same as the edge angle of the material tray 1, which helps the material tray 1 to be smoothly guided and positioned when entering and exiting the cache rack, reducing the jamming and collision of the material tray 1 during the movement process, and improving the fluency and efficiency of the overall operation. The second in-place detection assembly 34 is set to monitor in real time whether the material tray 1 has been correctly placed on the second cache rack 33. This function is particularly important for automated production lines because it can ensure that the material tray 1 performs the next operation at the correct time and position, thereby improving the automation and accuracy of the production line. The bending part 21b3 here has the same function as the bending part 21b3 on the first cache shelf 21, which will not be described again.

[0063] In some embodiments of the present invention, Fig.13 , Fig.17As shown, the output assembly 35 includes a sliding assembly 35a for the second cache rack 33 to slide on the frame 31, an output drive member 35b with one end fixed on the frame 31 and the other end fixed on the second bottom plate 33a, and a buffer 35c is also provided on the frame 31. The buffer 35c is configured so that when the second input port 33a1 is coaxially arranged with the first output port 21a1, the buffer 35c abuts against the second bottom plate 33a. The sliding assembly 35a with one end fixed on the frame 31 and the other end fixed on the second bottom plate 33a ensures the smooth sliding of the second cache rack 33 on the frame 31. This design reduces vibration and noise during movement, and improves the stability and reliability of the overall equipment. The output drive member 35b ensures that the second cache rack 33 can be accurately moved to the specified position, thereby improving the accuracy and efficiency of material processing. When the second input port 33a1 is coaxially arranged with the first output port 21a1, the buffer 35c abuts against the second bottom plate 33a. Through the buffering effect, the impact and vibration that may be generated by the second cache rack 33 during rapid movement or positioning are reduced, thereby avoiding damage to the equipment and extending its service life.

[0069] S30: The lateral transfer assembly 42 moves to the first output port 21a1, clamps the material tray 1 and transfers it to the lifting assembly 41, and the lifting assembly 41 rises to receive the material tray 1;

[0070] S40: After the material tray 1 is full or empty, the lateral transfer assembly 42 transports the material tray 1 to the first output port 21a1, and the longitudinal transfer assembly 32 receives the material tray 1 and moves it down to the second buffer shelf 33;

[0071] S50: the longitudinal transfer assembly 32 drives the material tray 1 to receive a new material tray 1 output from the first output port 21a1, thereby performing a cyclic transfer;

[0072] S60: When the material tray 1 on the second cache rack 33 is full, the longitudinal transfer component 32 moves to the outside of the second cache rack 33, and the output component 35 transfers the second cache rack 33 to the outside of the frame 31, unloads the material tray 1, and then moves back to the working position.
