[0064] The present invention will be described in further detail below with reference to specific embodiments:

[0065] like Figure 1 、 Figure 2 As shown, a storage structure includes a material rack 1, a feeding mechanism 2 and a storage and retrieval mechanism 3.

[0066] like Figure 1 As shown, the rack 1 has a driving area 11 inside, and the driving area 11 is arranged in a straight line. The two sides of the driving area 11 are storage areas 12, and the storage area 12 is used to store materials. It has several layers in the height direction; Figure 2 As shown, the longitudinal direction of the driving area 11 is set as the Y-axis direction, the horizontal direction perpendicular to the Y-axis direction is set as the X-axis direction, and the vertical direction perpendicular to the Y-axis direction is set as the Z-axis direction.

[0067] like Figure 2-5 As shown, the feeding mechanism 2 is fixed in the driving area 11 and is located at the end of the driving area 11, and includes a silo 21 for storing stacked materials and a first transfer component 22 for transferring materials in batches.

[0068] Regarding silo 21, Figure 3 、 Figure 4 As shown, the silo 21 has several workstations for stacking materials; the silo 21 includes a supporting plate 211 and a sleeve rod 212 fixed on the supporting plate 211; the supporting plate is positioned, and a roller is provided at the bottom and rollers are provided on both sides to facilitate the smooth placement of the supporting plate 211 loaded with materials at the designated position; the central axis of the sleeve rod 212 is provided along the Z-axis direction, and several sleeve rods 212 are fixed to the workstations corresponding to the materials and are distributed along the X-axis direction and the Y-axis direction; in this embodiment, three workstations are distributed along the X-axis direction and two workstations are distributed along the Y-axis direction in the silo 21, for a total of six workstations.

[0069] Regarding the first transfer component 22, as shown in FIG. Figure 4 、 Figure 5 As shown, the material is displaced in two directions, including a first driving member 221 that displaces the material along the Z-axis direction, and a second driving member 222 that displaces the material along the Y-axis direction; wherein:

[0070] a. The first driving member 221 includes a mounting frame 01, a suction cup 02 and a first actuator 03; the mounting frame 01 is horizontally arranged above the material, the suction cup 02 is fixed on the mounting frame 01 and distributed corresponding to the workstations, and the first actuator 03 drives the mounting frame 01 to move along the Z-axis direction to synchronously absorb the material on the top layer of each workstation; in this embodiment, the first actuator 03 uses a combination of a servo motor and a screw to drive the mounting frame 01 to move, and the movement stroke of the mounting frame 01 along the Z-axis is greater than the length of the sleeve rod 212, thereby ensuring that the mounting frame 01 can move to a position higher than the material.

[0071] b. The second driving member 222 includes a bracket 04 and a second actuator 05; the bracket 04 is located above the material, and has a notch 041 on its end surface that is aligned with the workstation. The notch 041 is arranged along the Y-axis direction, and the width of the notch 041 is smaller than the width of the material, and the material is supported above the notch 041; the second actuator 05 drives the bracket 04 to move along the Y-axis direction. In this embodiment, the second actuator 05 also adopts a combination of a servo motor and a screw rod; the bracket 04 that can be displaced has two workstations, including a loading workstation above the silo 21, and a feeding workstation that is completely moved out of the silo 21; as shown in FIG. Figure 4 As shown, the loading station corresponds to area A in the figure, and the feeding station corresponds to area B in the figure. When bracket 04 is in the feeding station, first actuator 03 drives suction cup 02 to absorb the material and move it upward; when bracket 04 is in the loading station, suction cup 02, which has absorbed the material, is above bracket 04.

[0072] Regarding the structure of the silo 21 and the first transfer assembly 22, the working principle of the feeding mechanism 2 is as follows. Figure 4 、 Figure 5 As shown:

[0073] (1) In the initial state, each station in the silo 21 is fully loaded with materials, and the amount of materials at each station is the same, that is, the height is the same;

[0074] (2) Bracket 04 is at the feeding station, corresponding to area B. At this time, the first actuator 03 is working, driving the mounting frame 01 to drive the suction cup 02 to move downward and simultaneously absorb the materials at the top of each station; after the absorption is completed, the mounting frame 01 continues to move upward so that the height of the absorbed materials is higher than the height of the end face of the bracket 04;

[0075] (3) The second actuator 05 drives the bracket 04 to move to the loading station, which corresponds to area A. Then, the first actuator 03 drives the mounting frame 01 to move downward, placing the material on the bracket 04. At this time, each material is supported above the slot 041;

[0076] (4) The second actuator 05 drives the bracket 04 to move to the feeding station, that is, Figure 4 、 Figure 5 The state shown is waiting for the next process to execute the action.

[0077] Regarding deposit and withdrawal mechanism 3, Figure 1 As shown, the storage and retrieval mechanism 3 is arranged in the driving area 11, and can perform lifting and lowering movements in the vertical direction, as well as reciprocating movements along the length direction of the driving area 11. It includes a guide seat 31 and a second transfer component 32 to realize the transfer of materials between the material rack 1 and the feeding mechanism 2.

[0078] Regarding the guide seat 31, Figure 2 As shown, the driving area 11 has a pair of parallel guide rails 13 at the upper and lower ends. The upper and lower ends of the guide seat 31 cooperate with the guide rails 13 and achieve displacement along the Y-axis direction through the seventh actuator; the seventh actuator is a combination of a servo motor, a synchronous pulley, and a synchronous belt. The guide seat 31 includes an upper seat 311, a lower seat 312, and a plurality of guide posts 313 connecting the upper seat 311 and the lower seat 312; the second transfer assembly 32 cooperates with the guide posts 313 and achieves displacement along the Z-axis direction through the eighth actuator; the eighth actuator is a combination of a servo motor, a synchronous pulley, and a synchronous belt. Regarding the configuration of the servo motor, synchronous pulley, and synchronous belt, since it belongs to the traditional transmission method, this embodiment will not be described in detail.

[0079] Regarding the second transfer assembly 32, as shown in FIG. Figure 6 As shown, when obtaining the material on the feeding mechanism 2, it needs to move to the side of the feeding station where the bracket 04 is located; the second transfer assembly 32 causes the material to be displaced in three directions, including a third driving member 321 that successively displaces the material along the Z-axis direction, a fourth driving member 322 that displaces the material along the Y-axis direction, a fifth driving member 323 that displaces the material again along the Z-axis direction, and a sixth driving member 324 that displaces the material along the X-axis direction; wherein:

[0080] a. Regarding the third driving member 321, Figure 7 As shown, the third driving member 321 includes a plug plate 06 and a third actuator 07; Figure 6As shown, the insert plate 06 is aligned with the slot 041 and is inserted into the slot 041 when the hopper 21 is in the feeding station, so that the material moves along the Z-axis direction through the third actuator 07. In this embodiment, the third actuator 07 is a lifting cylinder, and the number of lifting cylinders is the same as the number of stations where the material is distributed along the X-axis direction. Therefore, there are three lifting cylinders and three insert plates 06 in this embodiment.

[0081] b. Regarding the fourth driving member 322, as shown in FIG. Figure 7 As shown, the fourth driving member 322 includes a pair of transmission plates 08 and a fourth actuator 09. The fourth actuator 09 drives the pair of transmission plates 08 to open and close for supporting or unloading materials, or drives the pair of transmission plates 08 to move synchronously along the X-axis direction; wherein, the "open state" means that the distance between the pair of transmission plates 08 is greater than the width of the material, that is, Figure 9 As shown; "closed state" means the distance between a pair of transmission plates 08 is less than the width of the material, that is Figure 10 As shown. The positive direction of the X-axis is set as X1, and the negative direction of the X-axis is set as X2. When the pair of transmission plates 08 open and close, they move in the X1 and X2 directions, respectively. When the pair of transmission plates 08 move synchronously, they move simultaneously in the X1 or X2 directions. In this embodiment, the fourth actuator 09 uses a combination of a servo motor and a lead screw, with two sets provided, each corresponding to a pair of transmission plates 08. The pair of transmission plates 08 perform opening and closing movements corresponding to each position of the third actuator 07. A conveyor belt 081 that moves along the Y-axis is provided around the outer end surfaces of the pair of transmission plates 08. The conveyor belt 081 is driven by a servo motor, a drive shaft, and a synchronous pulley, driving the material supported above it to move along the Y-axis.

[0082] c. Regarding the fifth driving member 323, Figure 8 As shown, the fifth driving member 323 includes a support plate 010 and a fifth actuator 011. The support plate 010 is arranged on the end side of the movement direction of the upper end surface of the conveyor belt 081 to support the material unloaded by a pair of transmission plates 08; the fifth actuator 011 drives the support plate 010 to move along the Z-axis direction; in this embodiment, the fifth actuator 011 uses a lifting cylinder, and the number of lifting cylinders is the same as the number of workstations for the material, and is distributed along the X-axis direction and the Y-axis direction; of course, when the subsequent loading tray 012 carries the material, not all lifting cylinders need to perform the action, and they can be reasonably controlled according to the specifications of the loading tray 012.

[0083] d. Regarding the sixth driving member 324, as shown in FIG. Figure 7 、 Figure 11As shown, the sixth driving member 324 includes a loading tray 012, a pair of clamping seats 013 for positioning the loading tray 012, and a sixth actuator 014; the end surface of the loading tray 012 has a cavity 0121 for the support plate 010 to pass through, and carries the material supported by the support plate 010 when it moves downward; the pair of clamping seats 013 move along the Y-axis direction to position or unload the loading tray 012, and the movement of the clamping seats 013 can be driven by a cylinder; as shown Figure 12 As shown, both side ends of a pair of clamping seats 013 have hooks 0131 for positioning the loading tray 012. When the pair of clamping seats 013 move close to each other, the hooks 0131 are used to cooperate with the loading tray 012 and can drive the loading tray 012 to move synchronously; when the pair of clamping seats 013 move away from each other, the hooks 0131 are separated from the loading tray 012, which facilitates the storage of the loading tray 012; the sixth actuator 014 is connected to the cylinder driving the clamping seat 013 and is installed under the loading tray 012. The driving clamping seat 013 drives the loading tray 012 to move along the X-axis direction and store it in the storage area 12; in this embodiment, the sixth actuator 014 uses a rodless cylinder.

[0084] The third driving member 321, the fourth driving member 322, the fifth driving member 323 and the sixth driving member 324 need to cooperate with each other during operation. The inserting plate 06 performs an upward movement when the pair of transmission plates 08 are in the "open state", and the inserting plate 06 performs a downward movement when the pair of transmission plates 08 are in the "closed state". When the material height is higher than the upper end surface of the transmission plate 08, the pair of transmission plates 08 switches from the "open state" to the "closed state".

[0085] The support plate 010 performs an upward movement when a pair of transmission plates 08 are in the "closed state", and performs a downward movement when a pair of transmission plates 08 are in the "open state"; when the support plate 010 is against the lower end surface of the material, the pair of transmission plates 08 switches from the "closed state" to the "open state".

[0086] Based on the structure of the guide base 31 and the second transfer assembly 32, the working principle of the access mechanism 3 is as follows:

[0087] (1) Combination Figure 2 As shown, the eighth actuator drives the second transfer assembly 32 to move to a specified height, as shown in FIG. Figure 6 As shown, it is necessary to ensure that the inserting plate 06 can be inserted into the slot 041 and is lower than the height of the material on the bracket 04;

[0088] (2) The seventh actuator drives the second transfer assembly 32 to move toward the side of the bracket 04 at the feeding station, and inserts the insert plate 06 into the slot 041; the third actuator 07 drives the insert plate 06 to move upward and lift the material; then the seventh actuator drives the second transfer assembly 32 to move in the opposite direction, so that the material is moved out with the insert plate 06 to the corresponding position of the designated storage area 12;

[0089] (3) Figure 7 As shown, a pair of transmission plates 08 moves to above any inserting plate 06, and is located on both sides of the corresponding inserting plate 06, and is in the "open state", and the corresponding inserting plate 06 drives the material to pass through the pair of transmission plates 08 and move upward, so that the material height is higher than the height of the upper end surface of the transmission plate 08; then, the pair of transmission plates 08 switches to the "closed state", and moves along the X1 direction and the X2 direction respectively, so as to approach each other; the inserting plate 06 continues to drive the material to move downward until the material is supported on the transmission plate 08; the conveyor belt 081 around the transmission plate 08 works to convey the material at the head end of the transmission plate 08 to the tail end; at this time, if the material is aligned with the cavity 0121 on the loading tray 012, there is no need to adjust the position. If the material is not aligned with the cavity 0121 on the loading tray 012, the fourth actuator 09 drives the pair of transmission plates 08 to move synchronously, and adjusts the material to above the cavity 0121 where no material is loaded;

[0090] (4) Figure 8 As shown, the fifth actuator 011 drives the support plate 010 to move upward through the cavity 0121 on the loading tray 012 and lifts the material supported on the transmission plate 08 upward; then, the pair of transmission plates 08 switches to the "open state" and moves in the X1 direction and the X2 direction respectively, so as to move away from each other; then the support plate 010 drives the material to move downward through the pair of transmission plates 08 until the material is supported on the loading tray 012; during this process, if the corresponding model of the loading tray 012 has only four cavities 0121, the corresponding four fifth actuators 011 will perform the action; if the corresponding model of the loading tray 012 has six cavities 0121, all corresponding fifth actuators 011 will perform the action;

[0091] (5) After the materials on the pair of transmission plates 08 are unloaded, they are synchronously moved in the X1 direction or the X2 direction, so that the pair of transmission plates 08 move to the two sides of another inserting plate 06 loaded with materials, and the above steps (3) and (4) are repeated to transfer the materials on the inserting plate 06 to the loading tray 012;

[0092] (6) After all the materials on the insert plate 06 are transferred to the loading tray 012, or after the loading tray 012 is fully loaded with materials, Figure 11As shown, the sixth actuator 014 drives the loading tray 012 to move toward the side of the storage area 12 along the X-axis direction, and the base 013 used to position the loading tray 012 moves away along the Y-axis direction, so that the hook 0131 disengages from the loading tray 012, and then the loading tray 012 and the materials are stored in the storage area 12 at the same time.

[0093] (7) The seventh and eighth actuators operate to move the second transfer assembly 32 to the side of the storage area 12 where no materials are stored. The sixth actuator 014 drives the pair of clamps 013 to move to the side of the other empty loading tray 012. The pair of clamps 013 move closer to each other, so that the hook 0131 positions the loading tray 012 and transfers the loading tray 012 to the top of the support plate 010 for the next material loading, and the cycle repeats.

[0094] The present invention can perform bidirectional actions. The above working principle explains the process of transferring materials from the silo 21 to the loading tray 012 and entering the storage area 12 with the loading tray 012; of course, the materials stored in the storage area 12 can also be transported in reverse and stacked in the silo 21. During this process, the sixth actuator 014 is used to pull the fully loaded loading tray 012 out of the storage area 12 and push the empty loading tray 012 back to the storage area 12.

[0095] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention.
