Description

Technical Field

[0001] This invention belongs to the field of warehousing equipment technology, and in particular relates to a multifunctional storage rack with flip-up shelves. Background Technology

[0002] With the rapid development of the logistics and warehousing industry, the requirements for warehouse space utilization and operational efficiency are constantly increasing. Warehouse racks typically consist of uprights and multiple layers of horizontally fixed shelves. They are simple in structure, low in cost, and widely used in warehouses, workshops, and retail locations.

[0003] However, in actual use, because the shelves adopt a fixed horizontal installation structure, when goods need to be placed on the middle and lower shelves, the upper shelves will form obvious physical obstructions, resulting in limited operating space. It is difficult for staff to put the goods in smoothly and directly. For large and heavy goods, the angle needs to be adjusted repeatedly for insertion, and sometimes multiple people need to cooperate. During the operation, the goods are prone to tipping over due to unstable posture, posing a safety hazard and prolonging the normal storage and retrieval operation cycle.

[0004] Therefore, there is a particular need for a multi-functional storage rack with flip-up shelves to solve the above problems. Summary of the Invention

[0005] To overcome the shortcomings of existing shelving with fixed shelves, upper shelves obstructing access to lower shelves, and causing goods to tip over and posing safety risks, this invention provides a multi-functional storage rack with flip-up shelves.

[0006] This invention is achieved through the following technical means: a multi-functional storage rack with flip-up shelves, comprising a frame, fixed plates, shelves, limiting strips, and pulleys. Four layers of fixed plates are fixedly connected to the frame, with two fixed plates symmetrically distributed on each layer. Four shelves are rotatably arranged vertically at equal intervals on the frame. Limiting strips are fixedly connected to the fixed plates. Two pulleys are rotatably arranged on both the front and rear sides of the shelves. The rack also includes spur gears, a drive motor, a lead screw, sliding rods, a connecting plate, guide rods, springs, and racks. Two spur gears are symmetrically rotatably arranged on the right side of the shelves. A drive motor is installed on the top of the frame. A lead screw is fixedly connected to the output shaft of the drive motor. Three vertically distributed sliding rods are threaded through the lead screw. Connecting plates are fixedly connected between the front and rear ends of the three sliding rods. Seven guide rods are fixedly connected inside the connecting plates. The seven guide rods are distributed in three areas. A rack is slidably arranged between the guide rods in the same area. Springs are sleeved on the guide rods. The left and right ends of the springs are connected to racks and the inner wall of the connecting plate, respectively.

[0007] Preferably, the wheel surface of pulley two maintains rolling contact with the top surface of the limiting strip.

[0008] Preferably, it also includes limiting rods, with two limiting rods symmetrically fixed to the right side of the frame, and the limiting rods passing vertically through the sliding rod.

[0009] Preferably, the assembly also includes a guide plate, a limiting plate, a spring, a pulley, and a wedge plate. The guide plate is fixedly connected to the fixed plate, and the limiting plate is slidably mounted on the guide plate. The bottom surface of the limiting plate presses against the wheel surface of the corresponding pulley. Two springs are fixedly connected between the limiting plate and the guide plate. A pulley is rotatably mounted on the right end of the guide plate. Three wedge plates are vertically mounted on the sides of the two connecting plates that are far apart from each other. The movement trajectory of the wedge plates intersects with the position of the pulley.

[0010] Preferably, the frame also includes guide rails, a lifting frame, slide rails, sliding plates, electric push rods, shovels, servo motors, transmission gears, and racks. Two guide rails are symmetrically installed on both the front and rear sides of the frame. A lifting frame is slidably arranged between the four guide rails. Two slide rails are installed on both the front and rear sides of the right side of the lifting frame. A sliding plate is slidably arranged between the two slide rails on the same side. An electric push rod is installed on the sliding plate. The piston rod end of the electric push rod is fixedly connected to the lifting frame. A shovel is installed between the left ends of the two sliding plates. Two servo motors are installed side by side on the lifting frame. A transmission gear is fixedly connected to the output shaft of the servo motor. Racks are installed on both the front and rear sides of the left side of the frame. The transmission gear meshes with racks on the same side.

[0011] Preferably, the piston rod of the electric actuator is initially in the extended state, and the sliding plate is initially located at the leftmost end of the slide rail.

[0012] Preferably, the frame also includes a support frame, which is installed on the right side of the middle of the frame. The lower ends of the lead screws all pass vertically through the support frame and form a rotational engagement with the support frame. The bottom end of the limiting rod is fixedly connected to the support frame.

[0013] Preferably, it also includes pulleys three, with five pulleys three rotatably arranged on both the front and rear sides of the lifting frame, and the wheel surface of the pulleys three maintaining rolling contact with the frame surface.

[0014] Preferably, it also includes a fourth pulley, which is rotatably mounted on the sliding plate, and the wheel surface of the fourth pulley maintains rolling contact with the surface of the lifting frame.

[0015] Preferably, the device also includes rollers, with two rollers symmetrically rotated on the upper part of the lifting frame, and the wheel surfaces of the rollers maintaining rolling contact with the surface of the shovel plate.

[0016] The beneficial effects of the present invention are: 1. By setting up an upward-flipping shelf, in conjunction with a drive motor, lead screw, sliding rod and connecting plate, the rack can accurately mesh with the spur gear when it moves down, driving the upper shelf to flip upward to avoid obstruction, effectively eliminating the obstruction of the operating space of the lower shelf, and facilitating the smooth placement of goods.

[0017] 2. By setting a guide plate, a limiting plate and spring 1, the shelf is normally limited to a horizontal state to prevent unexpected rotation. When the connecting plate drives the wedge plate to move down, the wedge plate pushes pulley 1, causing the limiting plate to move laterally and disengage from pulley 2, realizing the automatic linkage of shelf unlocking and flipping. The structure is reliable and responds promptly.

[0018] 3. The automatic lifting of the lifting frame is achieved by driving the transmission gear along the rack and pinion via a servo motor. In conjunction with the electric push rod driving the sliding plate to move laterally along the slide rail, the shovel accurately delivers the support frame to the target shelf, completing the automated placement of goods and significantly improving warehousing efficiency and operational safety.

[0031] Example: A multi-functional storage rack with flip-up shelves, such as... Figures 1-4 and Figures 7-11 As shown, the system includes a frame 1, a fixing plate 2, shelf 3, a limiting strip 4, and pulleys 5. Four fixing plates 2 are fixedly connected to the frame 1, with two fixing plates 2 symmetrically distributed in each layer. Four shelf 3s are rotatably mounted on the frame 1, vertically and equidistantly distributed. Limiting strips 4 are fixedly connected to the fixing plates 2. Two pulleys 5 are rotatably mounted on both the front and rear sides of each shelf 3. The wheel surfaces of the pulleys 5 maintain rolling contact with the top surfaces of the limiting strips 4, thus restricting the shelf 3 to a horizontal state, allowing it to initially only rotate upwards. The system also includes a spur gear 6, a drive motor 7, a lead screw 8, a sliding rod 9, a limiting rod 91, a connecting plate 10, a guide rod 1001, a spring 1002, and a rack 11. Two spur gears 6 are symmetrically mounted on the right side of each shelf 3. The top of the frame 1 is bolted to the drive motor 7, which... A lead screw 8 is fixedly connected to the output shaft. The output shaft of the drive motor 7 extends vertically downward, and the lead screw 8 is fixedly connected to the output shaft via a coupling. Three vertically distributed sliding rods 9 are threaded through the lead screw 8. Two limiting rods 91 are symmetrically fixedly connected to the right side of the frame 1. The limiting rods 91 pass vertically through the sliding rods 9 to provide movement guidance for the sliding rods 9 and prevent the sliding rods 9 from deflecting under the drive of the lead screw 8. Connecting plates 10 are fixedly connected between the front and rear ends of the three sliding rods 9, respectively. Seven guide rods 1001 are fixedly connected inside the connecting plate 10. The seven guide rods 1001 are distributed in three areas. A rack 11 is slidably arranged between the guide rods 1001 in the same area. A spring 1002 is sleeved on the guide rod 1001. The left and right ends of the spring 1002 are connected to the rack 11 and the inner wall of the connecting plate 10, respectively.

[0032] like Figures 7-10As shown, it also includes a guide plate 201, a limiting plate 202, a spring 203, a pulley 204, and a wedge plate 205. The guide plate 201 is fixedly connected to the fixed plate 2. The limiting plate 202 is slidably mounted on the guide plate 201. The bottom surface of the limiting plate 202 presses against the wheel surface of the corresponding pulley 5, thereby limiting the pulley 5 and the layer plate 3 to the current horizontal state, preventing the layer plate 3 from rotating unexpectedly. Two springs 203 are fixedly connected between the limiting plate 202 and the guide plate 201. A pulley 204 is rotatably installed on the right end of 201. Three wedge plates 205 are bolted to the two connecting plates 10 on opposite sides. The movement trajectory of the wedge plates 205 intersects with the position of the pulley 204. When the connecting plate 10 moves the wedge plates 205 downward, the wedge plates 205 contact the corresponding pulley 204 and push the pulley 204 through the inclined plane, so that the limiting plate 202 overcomes the elastic force of the spring 203 and moves to the right, thereby disengaging from the wheel surface of the corresponding pulley 25 and releasing the limiting of the layer plate 3.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, it also includes guide rails 12, lifting frame 13, slide rails 14, sliding plate 15, electric push rod 16, shovel plate 17, servo motor 18, transmission gear 181, and rack 19. Two guide rails 12 are bolted to both the front and rear sides of the frame 1. The lifting frame 13 is slidably mounted between the four guide rails 12. Two slide rails 14 are bolted to both the front and rear sides of the right side of the lifting frame 13. A sliding plate 15 is slidably mounted between the two slide rails 14 on the same side. An electric push rod 16 is bolted to the sliding plate 15. The piston rod of 6 extends horizontally to the right, and the end of the piston rod is fixedly connected to the lifting frame 13. The piston rod of the electric push rod 16 is initially in the extended state. The sliding plate 15 is initially located at the leftmost end of the slide rail 14. The left ends of the two sliding plates 15 are connected by bolts to the shovel plate 17. The lifting frame 13 is connected by bolts to two servo motors 18. The output shaft of the servo motor 18 is fixedly connected to the transmission gear 181. The front and rear sides of the left side of the frame 1 are connected by bolts to rack 19. The transmission gear 181 meshes with the rack 19 on the same side.

[0034] like Figure 1 and Figure 10 As shown, it also includes a support frame 101. The support frame 101 is bolted to the right side of the middle part of the frame 1. The lower ends of the lead screws 8 all pass vertically through the support frame 101 and form a rotational engagement with the support frame 101. The bottom end of the limiting rod 91 is fixedly connected to the support frame 101.

[0035] like Figures 4-6As shown, it also includes pulleys 131. Five pulleys 131 are rotatably arranged on both the front and rear sides of the lifting frame 13. The wheel surface of the pulleys 131 maintains rolling contact with the surface of the frame 1, thereby improving the lifting stability of the lifting frame 13.

[0036] like Figure 5 As shown, it also includes a pulley four 151. The pulley four 151 is rotatably mounted on the sliding plate 15. The wheel surface of the pulley four 151 maintains rolling contact with the surface of the lifting frame 13, thereby reducing the sliding resistance of the sliding plate 15.

[0037] like Figure 4 As shown, it also includes rollers 171. Two rollers 171 are symmetrically and rotatably arranged on the upper part of the lifting frame 13. The wheel surface of the rollers 171 maintains rolling contact with the surface of the shovel plate 17 to ensure that the shovel plate 17 moves smoothly.

[0038] In use, first place the support frame 20 on the shovel plate 17, and then stack goods on the support frame 20. Then start the drive motor 7, which drives the lead screw 8 to rotate clockwise, driving the three sliding rods 9 to move down synchronously. The connecting plate 10 also descends. When the bottommost rack 11 moves down and meshes with the spur gear 6 of the second shelf 3, the rack 11 pushes the spur gear 6 to rotate, causing the second shelf 3 to flip upward, thus avoiding the operating space of the first shelf 3. During the meshing process, the rack 11 can slide into the connecting plate 10 along the guide rod 1001 and compress the spring 1002, which plays an adaptive role and avoids jamming. At the same time, the downward movement of the connecting plate 10 drives the wedge plate 205 to move down synchronously. The bottommost wedge plate 205 contacts the corresponding pulley 204. By pushing pulley 204 through the inclined plane, the limiting plate 202 overcomes the tension of the left spring 203 and compresses the right spring 203, moving to the right and thus disengaging from the corresponding pulley 5, releasing the limitation on the second shelf 3, allowing the second shelf 3 to flip freely. Then, the electric push rod 16 is activated, controlling the piston rod of the electric push rod 16 to retract, pulling the sliding plate 15 to slide to the right along the slide rail 14. When the sliding plate 15 reaches the rightmost end of the slide rail 14, the shovel plate 17 sends the support frame 20 onto the first shelf 3, so that the bottom surface of the support frame 20 contacts the bearing surface of the first shelf 3. At this time, the piston rod of the electric push rod 16 is extended again, driving the sliding plate 15 and the shovel plate 17 to move to the left and reset. The support frame 20 and the goods on it remain on the first shelf 3. When goods need to be stacked onto the second shelf 3, first control the drive motor 7 to reverse, causing the lead screw 8 to rotate counterclockwise. The connecting plate 10 moves upward, and the bottommost rack 11 disengages from the spur gear 6 of the second shelf 3. During disengagement, rack 11 drives the spur gear 6 to rotate in the opposite direction, causing the second shelf 3 to flip downward back to a horizontal position. When the bottommost rack 11 continues to move upward and passes the spur gear 6 of the third shelf 3, immediately control the drive motor 7 to rotate the lead screw 8 clockwise, causing the bottommost rack 11 to move downward and mesh with the spur gear 6 of the third shelf 3, driving the third shelf 3 to flip upward, thus avoiding the operating space of the second shelf 3. Then, place the support frame 20 and goods back on the shovel plate 17 and start the servo. Motor 18 drives transmission gear 181 to rotate. Transmission gear 181 meshes with rack 19 and rolls upward along rack 19. Lifting frame 13 rises accordingly until shovel 17 is raised to an appropriate height and the bottom surface of support frame 20 is aligned with the bearing surface of the second shelf 3. Then, the piston rod of electric push rod 16 is retracted again, causing sliding plate 15 to move shovel 17 to the right, sending support frame 20 onto the second shelf 3. The way goods are placed on the third shelf 3 is the same as on the second shelf 3. By driving the corresponding rack 11 to mesh with the spur gear 6 of the fourth shelf 3, the fourth shelf 3 is flipped upward to avoid the operating space of the third shelf 3. Then, support frame 20 is sent into the third shelf 3, thus achieving interference-free placement of goods on each layer.
