[0065] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0066] Example 1: See Figures 1 to 16 As shown, a vertical lifting cabinet system for intelligent storage and retrieval includes a cabinet body 1, a material tray 2, a material placement position 3, a material taking and placing device 4, a lifting device 5 and a material input and output device 6.

[0067] Cabinet:

[0068] See also Figures 1 to 3 , 10 to 12, the cabinet 1 includes a bottom frame 11, a top frame 12 and two groups of support modules 13, and the two ends of the bottom frame 11 and the top frame 12 are respectively connected to the bottom and top of the two groups of support modules 13;

[0069] The cabinet 1 further includes a plurality of side beams 14 , which are respectively disposed at the front and rear sides between the two groups of support modules 13 , and two ends of the side beams 14 are respectively connected to the two groups of support modules 13 .

[0070] The material placement positions are respectively set on the inner walls of the two groups of support modules, which are used to carry the material trays. Therefore, the support modules are the main load-bearing components, and the top frame and bottom frame are used to connect the top and bottom of the two groups of support modules to ensure that the distance between the tops and the bottoms of the two groups of support modules are equal, so as to ensure that the support modules will not fall or tilt, and also make them perpendicular to the horizontal plane. The side beams connect the middle parts of the two groups of support modules to further ensure that the middle parts of the two groups of support modules will not deform and ensure that the two groups of support modules will be parallel to each other.

[0071] The support module 13 includes a support seat assembly 131 and a plurality of column assemblies 132. The two sides of the base frame 11 are respectively connected to two groups of support seat assemblies 131 of the support module 13. The top of the column assembly 132 is connected to the side of the top frame 12.

[0072] The support seat assembly 131 includes a plurality of support columns 1310 and a connecting piece 1311. The plurality of support columns 1310 are arranged at intervals from front to back, and the plurality of support columns 1310 are connected to the connecting piece 1311. A height-adjusting foot cup 1312 is installed at the bottom of each support column 1310.

[0073] The bottom of each column assembly 132 is detachably connected to the top of a support column 1310 .

[0074] In this embodiment, the connecting piece acts as a crossbeam, which is used to connect and fix multiple support columns. The support column and the connecting piece are perpendicular, and the foot cup is used to adjust the height of the support column so that the support column is perpendicular to the horizontal plane. The support seat assembly is pre-assembled and debugged in the processing workshop, and then transported to the installation position of the lifting cabinet for rapid assembly. In this way, the support seat assembly is pre-adjusted, and when the lifting cabinet is assembled on site later, the support seat assembly is placed where it needs to be placed. The height adjustment foot cup is fine-tuned on site according to the plane of the installation position to ensure that the support column is perpendicular to the horizontal plane, and then the column assembly and the support column are connected to achieve rapid installation of the support module. In this way, adjacent support columns and column assemblies are parallel to each other and perpendicular to the horizontal plane, so that the entire cabinet has high precision and good safety and stability in use.

[0075] See also Fig.11 As shown, the connecting member 1311 includes an inner plate 1314 and multiple outer plates 1315. The inner sides of multiple support columns 1310 are connected to the inner plate 1314. Each of the outer plates 1315 is respectively arranged between adjacent support columns 1310, and both ends of the outer plates 1315 are connected to adjacent support columns 1310.

[0076] In this embodiment, there are 4 support columns and column assemblies in each support module. The inner plate and outer plate are made of straight plate, U-shaped plate (or U-shaped channel steel), hollow square plate (square channel steel) or plate-like material with inner opening. Preferably, U-shaped channel steel is used, which not only has good strength but also relatively low cost. During assembly, the inner wall of the column is connected to the outer wall of the inner plate, and the outer plate is arranged between adjacent support columns. The two ends of the outer plate are connected to two adjacent support columns. In this way, the outer side of the support column will not have an outer protrusion, which is more beautiful. The inner plate is arranged on the inner side of the support column, which is not exposed to the outside and can be conveniently connected and fixed to the chassis for maintenance.

[0077] The bottom of the column assembly 132 is connected to the top of the support column 1310 via a first locking member 1320 .

[0078] In this embodiment, the support column and the column assembly adopt U-shaped plates (U-shaped channel steel) or hollow square plates (directional channel steel), and U-shaped channel steel is preferably adopted, and its U-shaped opening is arranged inward, and the bottom surface of the column assembly is against the top surface of the support column, or there is a micro gap between the two, and the first locking member is sleeved on the outside of the connection between the support column and the column assembly, or is arranged on the inner wall of the connection between the support column and the column assembly. Taking the support column and the column assembly adopting U-shaped channel steel as an example, the first locking member also adopts U-shaped channel steel. In this embodiment, the first locking member is arranged on the inner wall of the connection between the support assembly and the column assembly, and the bolts lock and fix the upper and lower parts of the first locking member to the column assembly and the support column respectively. Of course, welding can also be used for fixing.

[0079] Similarly, due to different application scenarios, the height of the lifting cabinet is selected according to actual conditions. Therefore, the column assembly 132 includes multiple columns 1321, and the multiple columns 1321 are arranged in sequence from bottom to top. The bottom column 1321 is connected to the support column 1310; the adjacent columns are connected via the first locking member 1320. Similarly, each column is also a U-shaped channel steel opening inward, and the outer surface of the first connecting member contacts the inner wall of the adjacent column. The adjacent columns are connected by bolts, or welded to achieve the fixation of the adjacent columns. In this way, different numbers of columns can be rotated to form a column assembly according to the required height of the lifting cabinet, thereby adjusting the height of the lifting cabinet, so that the cabinet body can be modularly assembled and height adjusted.

[0080] Discharge position :

[0081] See also Figures 1 to 3 As shown, a plurality of support members 31 are provided on the inner wall of the cabinet 1, and the plurality of support members 31 are spaced from bottom to top, and a support spacing 32 is formed between adjacent support members 31, and the support spacing 32 on the left inner wall of the cabinet 1 corresponds to the support spacing 32 on the right inner wall of the cabinet 1 one by one, and the support spacing 32 on the left inner wall of the cabinet 1 and the support spacing 32 on the right inner wall of the cabinet 1 form the discharge position 3;

[0082] Each of the support members 31 is installed on the inner walls of at least two adjacent column assemblies 132 .

[0083] Among them, in this embodiment, four column assemblies are arranged on each support module, and the four column assemblies are arranged at intervals from front to rear. Multiple support members are installed on the inner walls of the two front column assemblies from bottom to top, and multiple support members are installed on the inner walls of the two rear column assemblies from bottom to top. The support members are arranged perpendicular to the column assemblies, and the multiple support members are arranged parallel to each other.

[0084] Since the support spacing is formed between adjacent support members, each support spacing on the left support module is directly opposite to each support spacing on the right support module, and the bottom surface of each support spacing on the left side is flush with the bottom surface of each corresponding support spacing on the right side, the left and right support spacings on the same plane form a discharge position, and the two sides of the material tray are respectively placed in a support spacing of the left support module and the right support module, so that the material tray is placed in a discharge position. Among them, the discharge position on the two front column assemblies on the left side and the two front column assemblies on the right side constitutes the front discharge position 33, and the discharge position on the two rear column assemblies on the left side and the two rear column assemblies on the right side constitutes the rear discharge position 34.

[0085] In this way, the support member can not only be used to support the material pallet, but also can be used to connect two adjacent column assemblies to ensure that the spacing between the two adjacent columns is consistent from bottom to top, thereby ensuring that the column is always perpendicular to the horizontal plane.

[0086] In this embodiment, since the support seat assembly is pre-processed and debugged, after the subsequent column assembly is installed, it is ensured that the support spacing on the left support module and the support spacing on the right support module correspond one to one and are respectively on the same plane, so that the two sides of the corresponding discharge position are flush, ensuring that the material tray can be stably placed in the discharge position.

[0087] Material tray:

[0088] See also Figure 4 , 5 As shown in 15, the material tray 2 is used to be placed in the cabinet 1, and a discharge cavity 21 is provided on the top of the material tray 2, and the discharge cavity 21 is used for storing materials.

[0089] Among them, since the discharge cavity is used for storing materials, different materials have different heights, and some materials are relatively high, which may be multiple times the height of a single support spacing. Therefore, in order to allow the ends of the material tray to be smoothly inserted into the support spacing on both sides without affecting the placement of materials into the cabinet and preventing adjacent material trays from interfering with each other, two support blocks 22 are respectively provided on the left and right sides of the material tray. The two support blocks 22 are spaced apart from each other, and the bottom surface of the support block 22 is flush with the bottom surface of the material tray, or the bottom plane of the support block is above the bottom plane of the material tray. The height of the support block is less than the height of the material tray, and the height of the support block is also less than the height of the support spacing. When the material tray is placed in the discharge position, the support blocks on both sides thereof are respectively against the support spacing, and the bottom surface of the support block is against the top surface of the support member, and the material tray is supported by the support member and the support block.

[0090] At the same time, downwardly extending extension plates 23 are respectively arranged on the front and rear sides of the left and right ends of the material tray 2. The four extension plates 23 are respectively arranged on the left and right sides of the front end and the left and right sides of the rear end of the material tray 2. A groove 24 is provided at the bottom of the extension plate 23. The groove is connected to the outer side wall of the corresponding extension plate. The groove is set to cooperate with the material taking and putting device, so that the material taking and putting device can drive the material tray to move forward and backward through the groove.

[0091] Loading and unloading device :

[0092] See also Figures 6 to 9 As shown, the material taking and placing device 4 is vertically movable and arranged in the cabinet 1 between the front material placing position 33 and the rear material placing position 34, and the material taking and placing device is used to take the material tray out of the material placing position or send it into the material placing position, and the material taking and placing device can also take the material tray out of the material loading and unloading device or send it into the material loading and unloading device.

[0093] The material taking and placing device 4 includes a bracket 41, a driving mechanism installed on the bracket 41 and two sets of tray driving components 42, and the lifting device 5 drives the bracket 41 to move vertically along the cabinet 1;

[0094] The two groups of tray driving components 42 are symmetrically arranged on the left and right sides of the bracket 41, and the tray driving components 42 include a transmission chain 43, two transmission gears 44 and two transmission members 45. The two transmission gears 44 are rotatably installed on the side wall of the bracket 41 at a front-back interval, the transmission chain 43 is wound around the two transmission gears 44, and the two transmission members 45 are installed on the inner side wall of the transmission chain 43 at intervals.

[0095] The driving mechanism is installed on the bracket 41 , and the driving mechanism drives the transmission chains 43 on both sides to rotate simultaneously.

[0096] In this embodiment, the left and right sides of the bracket are respectively connected to the cabinet body for vertical movement. In this embodiment, the middle part of the bracket is a hollow structure, and two sets of tray driving members are installed on the inner wall of the hollow part. Two transmission gears are arranged at intervals in front and back, and the line between the top surfaces of the two transmission gears is arranged parallel to the top surface of the support. The driving mechanism is installed in the hollow structure, and drives the transmission chains on both sides to transmit in the same direction at the same time.

[0097] Since two transmission members are installed on the inner wall of the transmission chain, the distance between the two transmission members is equal to the distance between the two grooves. Since the groove is below the material tray, the transmission member is used to be inserted into the groove, and then through the movement of the transmission chain, the transmission member inserted into the groove simultaneously pulls the material tray to move, thereby realizing the movement of the material tray to the bracket, or from the bracket to the discharge position, feeding and discharging device.

[0098] The transmission member 45 includes a mounting block 46 and a transmission rod 47 disposed on the inner wall of the mounting block 46 . The mounting block 46 is mounted on a chain plate of the transmission chain 43 , and the transmission rod 47 is mounted on the inner side wall of one end of the mounting block 46 .

[0099] When the transmission chain at the transmission member rotates to the end side of the transmission gear and moves upward, the transmission member moves upward following the transmission chain and is inserted into the groove;

[0100] When the transmission chain at the transmission member rotates to the end side of the transmission gear and moves downward, the transmission member moves downward following the transmission chain and disengages from the groove.

[0101] In this embodiment, the mounting block is connected to both ends of a chain plate, the transmission chain is composed of multiple chain plates, and the transmission rod is connected to one end of the inner side of the mounting block. When the material tray needs to be moved, the bracket is first moved to the position at the height of the material tray to be moved. For example, when the material tray on the front discharge position is taken out, the transmission rod is at the lower end side between the two transmission gears. A stop bar 35 is set in each support spacing. The stop bar in the front support spacing is set at the front side of the support spacing to prevent the material tray from moving forward and leaving the cabinet body, and limit its forward movement distance. The stop bar in the rear support spacing is close to the rear side of the support spacing, which limits the material tray from moving backward and leaving the cabinet body, and limits the position of the material tray. When the material discharging device needs to be able to hook the material tray to move. The rear end of the material tray in the front discharge position will be outside the rear side of the support below it, and the front end of the material tray in the rear discharge position will be outside the front side of the support below it. The ends of the two transmission gears will face the ends of the material tray and have a slight gap. At this time, the top of the transmission chain moves backward, and the transmission chain under the transmission gear moves forward. When the transmission member moves to the bottom of the front transmission gear and moves upward (moves to the end of the transmission gear), the angle of the mounting plate will change from horizontal state - tilted upward from left to right - vertical state - tilted upward from right to left - horizontal (turned 180 degrees at this time). In the process of tilting upward from left to right to vertical state, the transmission rod will enter the groove. In the process of vertical state - tilting upward from right to left - horizontal, since the transmission rod is in the groove and the transmission rod is on the upper side of the transmission gear at this time, it will move backward with the transmission chain, driving the material tray to move backward and move to the bracket. When the other When the transmission member rotates to the transmission gear on the front side, it will face the groove at the front end of the material tray and hook into the groove at the front end, and then continue to drive the material tray to move backward. At this time, the two transmission members are respectively at the top of the two transmission gears, so that the material tray is completely moved to the bracket, the transmission chain stops rotating, and then the lifting device drives it to move to the corresponding height, for example, to the front side of a rear side discharge position below, and then the transmission chain continues to keep the top moving backward, driving the material tray to move backward. At this time, the transmission rod at the transmission gear on the rear side moves to the rear end (end) of the transmission gear and moves downward, and it will move downward to disengage from the groove at the rear end of the material tray, and the other transmission rod continues to move backward, pushing the material tray to continue to move backward into the rear side discharge position. When the material tray completely enters the rear side discharge position, the other transmission rod also rotates to the rear end of the transmission gear on the rear side and moves downward to disengage from the groove at the front end of the material tray, thereby realizing separation from the material tray. At this time, the bracket moves up and down and will not collide with the material tray.Therefore, according to the above principle, the forward and backward movement of the material tray is realized according to the forward and reverse rotation of the transmission chain. When the transmission chain is driven, the forward and backward movement of the material tray is realized through the cooperation of the transmission rod and the corresponding groove.

[0102] In this embodiment, the left and right sides of the top of the bracket 41 are respectively provided with inwardly extending support plates 48, which are located above the transmission chain and are arranged close to the transmission chain. When the transmission rod pulls the material tray to move to the bracket, the support blocks at both ends thereof respectively abut against the support plates on both sides of the bracket, and the material tray is supported by the support plates and the support blocks. At the same time, in order to ensure that the support blocks abut against the support plates smoothly and will not be stuck by the ends of the support plates, guide plates 49 inclined downward toward the corresponding sides are respectively arranged at both ends of the support plates, so that when the transmission rod pulls the material tray to move toward the bracket, the support blocks are guided by the guide plates and abut against the support plates.

[0103] The bracket can be connected to the column assembly in a vertical sliding manner, or can be connected to the column assembly in a vertical sliding manner by rolling contact between the roller and the column assembly.

[0104] See also Figure 6 , 7 As shown, the driving mechanism includes a first motor assembly 410, a first connecting shaft 411, and driving gears 412 respectively arranged at both ends of the first connecting shaft 411. The first motor assembly 410 is mounted on the bracket 41. The first connecting shaft 411 is rotatably connected to the bracket 41, and the first connecting shaft 411 is arranged parallel to the axis of the transmission gear 44. The two driving gears 412 are respectively engaged with the transmission chains 43 on both sides. The first motor assembly 410 drives the first connecting shaft 411 to rotate, and drives the transmission chains 43 on both sides to rotate through the driving gears 412. Thus, two sets of transmission chains are driven to transmit in the same direction at the same time.

[0105] In this embodiment, a sensor is also set on the side wall of the bracket, and an upper detection block and a lower detection block are set on the inner wall of the cabinet. The sensor can detect the moving height position of the bracket. If the sensor detects the upper and lower detection blocks, it means that the bracket has moved to the upper and lower limit positions and cannot move further, thereby ensuring safety and reducing safety hazards.

[0106] Lifting device :

[0107] See also Figure 2 , 9 As shown, the lifting device 5 is used to drive the material taking and placing device to move vertically and move the material taking and placing device to any height position, so that the material taking and placing device faces the material placing position at any position and faces the material inlet and outlet device.

[0108] The lifting device 5 includes a lifting transmission motor 51 and two sets of side transmission belts 52. The upper pulley and the lower pulley are respectively provided on the left and right sides of the inner wall of the cabinet 1. The two sets of side transmission belts are respectively wound around the upper and lower pulleys on both sides. The lifting transmission motor is arranged at the bottom of the cabinet and also includes a transverse transmission rod 53. The two ends of the transverse transmission rod are respectively connected to the lower pulleys on both sides. The lifting transmission motor drives the transverse transmission rod to rotate, and at the same time drives the lower pulleys on both sides to rotate, and drives the side transmission belts on both sides to rotate. Among them, the two ends of the bracket are respectively connected to the side transmission belts on both sides. When the side transmission belts rotate, the bracket is driven to move up and down, thereby realizing the vertical movement of the material taking and placing device.

[0109] Feeding and discharging device :

[0110] See also Figure 1 , 2 , 13~16 The rear end of the material loading and unloading device 6 is arranged below the lowest front side material discharge position, and the front end of the material loading and unloading device is arranged outside the front end of the cabinet. The material loading and unloading device is used to deliver the material tray into the cabinet or deliver the material in the cabinet out of the cabinet, and the material taking and placing device can also deliver the material tray into the material loading and unloading device or take the material tray out of the material loading and unloading device.

[0111] The feeding and discharging device 6 includes a second driving mechanism and at least one set of feeding and discharging components;

[0112] The material inlet and outlet assembly includes two groups of support assemblies spaced apart from each other, the support assembly includes a support frame 61 and a slide frame 62, the rear end of the support frame 61 is connected to the inner wall of the cabinet 1 and is arranged directly below the front material discharge position 33, and the front end of the support frame 61 extends out of the cabinet 1 and is arranged outside the front side of the cabinet 1;

[0113] The slide 62 is slidably disposed on the support frame 61, the upper portion of the slide 62 is disposed above the top surface of the support frame 61, and the second driving mechanism drives the slide 62 to move forward and backward along the support frame 61;

[0114] A material pulling and pushing member 63 is also provided at the top front end of the slide 62 , and the material pulling and pushing member 63 is used to limit the material tray 2 on the slide 62 .

[0115] The rear end of the support frame is arranged below the lowest support member and is arranged parallel to the support member, and the front end thereof extends out of the cabinet and is located outside the cabinet. When it is necessary to take or place materials, the second driving mechanism drives the slide to move backward into the cabinet and is located directly below the support member. The material taking and placing device takes out the material tray on the placing position and places it on the material taking and placing device, and then moves to the rear side of the slide, and then sends the material tray to the support components on both sides. At this time, the support blocks on both sides of the material tray are against the top surfaces of the slides on both sides. At this time, the material pulling and pushing member will limit the support blocks of the material tray, and then the second driving mechanism drives the slide to move forward. Since the material pulling and pushing member limits the support blocks on the slide, when the slide moves forward, it will drive the material tray to move forward and out of the cabinet at the same time, and then the personnel, manipulators or other mechanisms outside the cabinet will take out the materials in the material tray, or put the materials into the material tray. After the material picking and placing is completed, the second driving mechanism drives the slide to move backward, so that the slide moves into the cabinet and is directly below the front material placement position. Then the material picking and placing device pulls the material tray on the slide to the material picking and placing device, and then sends the material tray on the material picking and placing device to the corresponding material placement position.

[0116] See also Figures 14 to 16 As shown, the material pulling push member 63 includes a pushing block 631 and a material pulling member 632. The bottom of the pushing block 631 is fixedly installed on the top front end of the slide 62. The front end of the material pulling member 632 is rotatably connected to the pushing block 631. The rear end of the material pulling member 632 is provided with a hook 633 extending downward.

[0117] The rear end face of the hook 633 is an inclined surface 634 that tilts upward from front to back, and a decoupling rod 64 facing the inclined surface is provided on the side wall of the cabinet. An inclined decoupling hook 68 is provided on the top front side of the pulling piece, and the inclined decoupling hook is arranged opposite to the decoupling rod. When the slide moves backward, the decoupling rod contacts the inclined decoupling hook and pushes the rear end of the hook to rotate upward. The rear end face of the inclined decoupling hook is an inclined decoupling inclined surface 69 that tilts upward from front to back.

[0118] In this embodiment, the push block is arranged so that when the slide moves backward, the push block will abut against the front end surface of the support block at the front end of the side of the material tray and push the material tray to move backward along with the slide. The material pulling member is a plate-shaped mechanism, and a notch is arranged on the top of the push block. The front end of the material pulling member is rotatably connected to the notch through a rotating shaft. Since the front end of the push-pull member is rotatably connected to the push block, the rear end of the push-pull member will automatically rotate downward under its own weight, and the bottom surface of the push-pull member will abut against the bottom surface of the notch. When the loading and unloading device pushes the material tray to move forward, the bottom surface of the support block will abut against the top surface of the slide, and the material tray moves forward. At this time, the bottom plane of the hook will be below the top plane of the support block, and due to the existence of the inclined surface, the support block on the front side will first contact the inclined surface. Since the inclined surface is inclined upward from front to back, the front end of the pulling member is rotatably connected with the pushing block, which will push the rear end of the pulling member to move upward through the inclined surface, and make the bottom surface of the hook abut against the top surface of the support block, and the material tray continues to move forward. When the support block at the front end continues to move forward until the support block on the front side moves forward until the front end of the hook, the pulling member is subjected to its own weight and its rear end rotates downward, causing the hook to rotate downward and be located at the rear side of the front block. At this time, the front end of the support block on the front side contacts the pushing block, and the material tray disengages from the loading and unloading device, and then the second driving mechanism drives the slide to move forward. When the slide moves forward, the hook will hook the support block on the front side, and drive the support block and the material tray to move forward, so that it moves out of the cabinet.

[0119] When the slide moves backward, the push block will push the material tray to move backward. In order to achieve the separation of the hook support block, a unhooking rod is set on the side wall of the cabinet. The height of the unhooking rod will be above the top plane of the support block and opposite to the unhooking inclined surface. When the support block moves backward, when the slide moves backward and is about to reach the rear end, the unhooking rod moves to face the unhooking inclined surface and contacts the unhooking inclined surface, and pushes the oblique unhooking to rotate upward through the unhooking rod, so that the hook follows the upward rotation and separates from the support block, and the subsequent material taking and releasing device can normally pull the material tray backward to separate from the slide and pull the material parts.

[0120] In this embodiment, there are two groups of material input and output components, and the two groups of material input and output components are arranged at an interval up and down, so that the two groups of material input and output devices can drive two groups of material trays to move at the same time, one group of material trays moves backward, and one group of material trays moves forward, that is, the material trays go in and out one by one, which improves the convenience of taking and placing materials, when taking materials from one group of material trays.

[0121] In this embodiment, the second driving mechanism includes a second motor 651, a second transmission rod 652 and a plurality of belts.

[0122] Two support frame pulleys 653 are provided on the inner wall of each support frame 61, and the two support frame pulleys 653 are spaced apart from each other, and a belt 654 is wound around the two support frame pulleys 653. The slide on the upper material inlet and outlet assembly is connected to the belt on the upper support frame, and is connected to the belt above the support frame pulley, and the slide on the lower material inlet and outlet assembly is connected to the belt on the upper support frame, and is connected to the belt below the support frame pulley. A side panel 655 is provided on the left and right sides of the front end of the cabinet body, and the side panel is connected to the corresponding upper and lower groups of support frames. A plurality of outer pulleys 656 are provided on the side panel, and a belt 654 is provided on the outer side of each side of the side panel. The belt is wound around the outer pulley on the outer side of the corresponding side panel, and two of the outer pulleys are respectively connected to a support frame pulley at the front end of the two support frames, and the two ends of the second transmission rod are respectively connected to two oppositely arranged outer pulleys. The second motor drives the second transmission rod to rotate, and drives the belt and the outer pulley on the outer side of the side panel to rotate. When the outer pulley rotates, it will simultaneously drive the rotation of the support frame pulleys in the two groups of feeding and discharging components. When the support frame pulley rotates, it will also drive the belt transmission thereon, and then drive the slide to move. When the outer belt of the side panel is driven, the upper support frame pulley and the lower support frame pulley in the two groups of feeding and discharging components will be driven to rotate in opposite directions. Therefore, the belts in the two groups of feeding and discharging components are driven to move in opposite directions, so that when one group of slides moves forward, the other group of slides moves backward, realizing the one-in-one-out action of the two groups of material trays.

[0123] A cross bar 66 is also provided, which is provided below the front end of the feeding and discharging device, and the two ends of the cross bar are connected to the bottom of the front end of the side panels on both sides. A control screen mounting frame 67 is slidably provided on the cross bar, and the control screen mounting frame is used to install the control screen. The operator can use the control screen to control the operation of the lifting cabinet or view the data of the lifting cabinet according to the operating habits, etc., without affecting the loading and unloading of materials. The control screen can be a tablet computer, which is used to control the automatic operation of the lifting cabinet and can also display some data of the lifting cabinet.

[0124] In the present invention, detection gratings are respectively arranged on the left and right sides below the front discharge position, which are used to detect the height of the material on the material tray sent into the cabinet by the feeding and unloading device, so that the subsequent material tray with materials of corresponding height can be sent to the corresponding discharge position. In this way, materials of different heights will not collide with the material tray in the upper discharge position, thereby ensuring the stability and quality of the discharge.
