[0001] The present invention belongs to the technical field of storage racks, and in particular relates to an automated three-dimensional inventory warehouse rack for door processing and production. Background Art

[0002] When storing door panels, use multi-layer storage racks; storage racks are widely used in the field of logistics and warehousing; when storing door panels, conventional door panels are stacked horizontally, which is inconvenient to take out, and long-term stacking may cause damage to the door panels; Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art and to propose an automated three-dimensional inventory warehouse rack for door processing and production.

[0004] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0005] An automated three-dimensional inventory warehouse rack for door processing and production, comprising a support frame, a cargo plate first fixed to the bottom of the support frame, a liftable middle cargo plate second, and a liftable top plate;

[0006] The top surfaces of cargo pallet 1 and cargo pallet 2 are both arranged with trapezoidal bracket 1 in an array, the bottom surface of cargo pallet 2 and the bottom surface of the top plate are both arranged with trapezoidal bracket 2, and L-shaped card plates are symmetrically installed at both ends of the side wall of trapezoidal bracket 2 to form a door panel placement slot;

[0007] When the cargo plate 2 is lowered, the trapezoidal support 2 at its bottom is embedded in the gap between the adjacent trapezoidal support 1 at the bottom to form a three-dimensional constraint network to limit the displacement of the door panel;

[0008] Pneumatic restriction structures are installed on both sides of the rear end of cargo plate 1 and cargo plate 2, including L-shaped restriction plates, air cylinder 1, air cylinder 2 and air cylinder 2's pressure rod. When trapezoidal support 2 descends, the pressure rod is triggered to drive the L-shaped restriction plates to retract, thus restraining the rear side of the door panel.

[0009] L-shaped inclined plates are arranged on both sides of the trapezoidal bracket, and ball bearings 1 and 2 are arranged on the inner wall of the trapezoidal bracket to reduce the friction of the door panel.

[0010] Preferably, the cargo plate 2 and the top plate are slidably connected to the support frame through a sliding frame.

[0011] Preferably, a hydraulic cylinder 1 is fixedly connected to the bottom of the support frame, and the output end of the hydraulic cylinder 1 is fixedly connected to the sliding frame installed on the side wall of the cargo plate 2. A hydraulic cylinder 2 is installed on the top of the sliding frame, and the output end of the hydraulic cylinder 2 is fixedly connected to the bottom end of the sliding frame installed on the side wall of the top plate.

[0012] Preferably, the air cylinder 2 of the pneumatic limiting structure includes a piston groove, a piston 2 is installed on the inner wall of the piston groove, and a return spring is installed between the bottom of the piston 2 and the bottom of the inner wall of the piston groove. After the pressure rod is pressed by the trapezoidal bracket 2, the compressed gas is sent to the air cylinder 1, driving the L-shaped limiting plate to move.

[0013] Preferably, the side wall and the bottom of the L-shaped leaning plate are respectively provided with a rolling groove 1 and a rolling groove 2, and the inner walls of the rolling groove 1 and the rolling groove 2 are respectively connected to the ball 1 and the ball 2 in a rolling manner.

[0014] Preferably, the bottom of the second ball is connected to a support plate, and the support plate is connected to a third hydraulic cylinder via a connecting rod and an integrated frame, and the third hydraulic cylinder drives the support plate to rise and fall.

[0015] Preferably, a thrust spring is provided on the inner side of the L-shaped limiting plate, and its two ends are respectively fixedly connected to the L-shaped limiting plate and a trapezoidal bracket for adaptively adjusting the thickness of the door panel.

[0016] Preferably, a guide hole is provided on one side wall of the trapezoidal bracket, and a guide rod passes through the guide hole and is connected to the L-shaped leaning plate to limit its lateral displacement.

[0017] Preferably, a stop plate is provided at the bottom of the L-shaped limiting plate, and a second slope and a third slope are provided on the top surface of the stop plate. A first slope is provided at the bottom of the L-shaped limiting plate, corresponding to the second slope and the third slope of the stop plate, which triggers the retraction of ball two when squeezed.

[0018] Preferably, the hydraulic cylinder one, hydraulic cylinder two and hydraulic cylinder three are controlled in series, and the lifting and lowering of cargo plate two and top plate synchronously adjust the contact state of ball two.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the present invention;

[0020] This automated three-dimensional inventory warehouse rack for door processing and production uses a cross-constraint design of multi-layer liftable shelves and ladder-shaped brackets to achieve oblique three-dimensional storage of door panels, effectively avoiding the risk of tipping and compression deformation caused by traditional horizontal stacking.

[0021] This is an automated three-dimensional inventory warehouse rack used for door processing and production. The three-dimensional constraint network formed by the trapezoidal bracket and the L-shaped pallet, combined with the dynamic response of the pneumatic restriction structure, automatically locks both sides of the door panel during the lifting and lowering of the cargo panel, significantly improving storage stability and space utilization.

[0022] This is an automated three-dimensional inventory warehouse rack used for door processing and production. The L-shaped inclined plate and its ball guide design greatly reduce the friction resistance when the door panel is pushed in, avoiding surface scratches. At the same time, through the adaptive adjustment of the ball retractable mechanism and hydraulic linkage, it is compatible with door panels of different thicknesses and prevents structural damage caused by extrusion.

[0023] This is an automated three-dimensional inventory warehouse rack used for door processing and production. The entire rack adopts hydraulic drive and pneumatic coordinated control to achieve automated and synchronous operation of door panel storage and retrieval, cargo panel lifting and lowering, and protection mechanisms, reducing the intensity of manual intervention. It is especially suitable for the efficient turnover and long-term storage needs of large quantities of door panels. At the same time, the optimized angle design of the double-bevel trapezoidal bracket further ensures that the door panels are evenly stressed, extending their service life.

DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0039] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0040] In the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] Example 1: Reference Figures 1-12 An automated three-dimensional inventory warehouse rack for door processing and production includes a shelf 1, which includes a support frame 101 and a layered system mechanism; the layered system mechanism is composed of a fixed bottom cargo plate 102, a liftable middle cargo plate 2 103 and a liftable top plate 104 to form a layered storage space:

[0042] Cargo pallet 102 is fixedly connected to the bottom of the support frame 101, and the top surfaces of cargo pallet 102 and cargo pallet 2 103 are both arranged in an array with trapezoidal brackets 1 2;

[0043] The bottom surface of the middle cargo plate 2 103 and the bottom surface of the top plate 104 are both provided with a trapezoidal bracket 2 3. L-shaped clamping plates 301 are symmetrically installed at both ends of the side walls of the trapezoidal bracket 2 3 to form a door panel placement groove 302 for restraining the door panel 10. By adopting a double-bevel guide design for the trapezoidal bracket 1 2 and the trapezoidal bracket 2 3, the door panel 10 can be leaned against at an angle without shaking or tipping over when placed upright.

[0044] When the middle cargo plate 2 103 executes the down command, the trapezoidal bracket 2 3 at its bottom is precisely embedded in the reserved gap between the adjacent trapezoidal bracket 1 2 of the bottom cargo plate 1 102, forming a three-dimensional constraint network, effectively improving the storage stability of the door panel 10; and restricting the door panel 10 leaning against the side wall of the trapezoidal bracket 1 2, so that the door panel 10 is placed more firmly;

[0045] Specifically: cargo plate 102 is fixedly installed at the bottom of the support frame 101, and both sides of cargo plate 102 and top plate 104 are fixedly connected with sliding frames 105, and the inner wall of the sliding frame 105 is slidably connected to the outer wall of the support frame 101. The bottom of the support frame 101 is fixedly connected with hydraulic cylinder 106, and the output end of hydraulic cylinder 106 is fixedly connected to the sliding frame 105 installed on the side wall of cargo plate 2 103. The top of the sliding frame 105 is fixedly installed with hydraulic cylinder 2 107, and the output end of hydraulic cylinder 2 107 is fixedly connected to the bottom end of the sliding frame 105 installed on the side wall of the top plate 104;

[0046] Furthermore, in the above solution, the door panels 10 leaning against the sides of cargo pallet 102 and cargo pallet 2 103 are at risk of sliding sideways. To this end, pneumatic restriction structures 4 are added to the rear ends of cargo pallet 102 and cargo pallet 2 103. The door panels 10 on both sides are restricted by retractable L-shaped restriction plates 404.

[0047] One end of the L-shaped limiting plate 404 is fixedly connected to the gas cylinder 1, and the inside of the cargo plate 1 102 and the inside of the cargo plate 2 103 are both provided with gas cylinder 2, the output end of gas cylinder 2 is connected to the input end of gas cylinder 1, and the input end of gas cylinder 2 is connected to the output end of gas cylinder 1; the top of gas cylinder 2 corresponds to the trapezoidal bracket 2 3;

[0048] When the trapezoidal support 2 3 descends, its bottom end pushes the pressure rod 407 of the gas cylinder 2 downward, driving the piston 2 406 to descend along the piston groove 405, and transmitting the internal gas into the gas cylinder 1 through the pipe connected between the output end of the gas cylinder 2 and the input end of the gas cylinder 1, pushing the piston 1 402 and pulling the L-shaped limiting plate 404 through the moving rod 403 to limit the door panel 10;

[0049] Specifically, the pneumatic restriction structure 4 includes an air cylinder 1, an air cylinder 2, and an L-shaped restriction plate 404. The air cylinder 1 includes a piston cylinder 1 401, which is fixedly mounted on the rear end of the trapezoidal bracket 1 2. The inner wall of the piston cylinder 1 401 is slidably connected to a piston 1 402. The top end of the piston 1 402 is fixedly connected to a moving rod 403. The end of the moving rod 403 away from the piston 1 402 is fixedly connected to the L-shaped restriction plate 404.

[0050] Gas cylinder 2 includes a piston groove 405 opened inside cargo plate 102 and cargo plate 2 103, the inner wall of the piston groove 405 is slidably connected to piston 2 406, the top of piston 2 406 is fixedly connected to a pressure rod 407, the top of the pressure rod 407 corresponds to the trapezoidal bracket 2 3, and a return spring 408 is fixedly installed on the bottom of the inner wall of the piston groove 405, and the top of the return spring 408 is fixedly connected to the bottom end of piston 2 406; the bottom output end of the piston groove 405 of gas cylinder 2 is connected to the top input end of the piston cylinder 1 401 of gas cylinder 1, and the top input end of the piston groove 405 of gas cylinder 2 is connected to the bottom output end of the piston cylinder 1 401 of gas cylinder 1;

[0051] Working principle: When the trapezoidal bracket 2 3 descends, its bottom end pushes the pressure rod 407 of the gas cylinder 2 downward, driving the piston 2 406 to descend along the piston groove 405, and transmitting the internal gas into the gas cylinder 1 through the pipe connected between the output end of the gas cylinder 2 and the input end of the gas cylinder 1, pushing the piston 1 402 to move downward, and pulling the L-shaped limiting plate 404 to move through the moving rod 403, thereby restricting the door panel 10 through the L-shaped limiting plate 404 and the trapezoidal bracket 1 2;

[0052] Furthermore, when the door panel 10 is pushed in from the front end and leans against the trapezoidal support 1 2, the oblique edge of its bottom contacts the top of cargo board 1 102 or cargo board 2 103, and the contact area becomes smaller. The pressure of the door panel 10 itself is concentrated, which may cause damage to the oblique edge of the bottom of the door panel 10 where it contacts cargo board 1 102 or cargo board 2 103. To this end, L-shaped oblique plates 6 are provided on both sides of the trapezoidal support 1 2 to support the inclined door panel 10. The bottom of the inclined door panel 10 contacts the bottom end of the inner wall of the L-shaped oblique plates 6, thereby increasing the contact force area of the bottom.

[0053] Furthermore, an array of rolling grooves 601 are formed on the outer wall of the L-shaped leaning plate 6, and a first ball 602 is rollingly connected to the inner wall of the first rolling groove 601; a second rolling groove 603 is formed in the bottom of the L-shaped leaning plate 6, and a second ball 604 is fixedly connected to the second rolling groove 603; when in use, one end of the door panel 10 is placed on the L-shaped leaning plate 6 and pushed inward; the rolling first ball 602 and second ball 604 reduce the contact area between the door panel 10 and the L-shaped leaning plate 6, thereby reducing friction and minimizing damage to the door panel 10 caused by friction;

[0054] Example 2: Reference Figures 1-12 , which is basically the same as Example 1, but there is a problem that, due to the different thicknesses of the door panels 10 placed in different batches, if the door panel 10 is thickened, when the trapezoidal bracket 2 3 is lowered and inserted into the gap between the two adjacent trapezoidal brackets 2 below, the thickened door panel 10 may be squeezed. To this end: further, the L-shaped leaning plate 6 is not fixedly connected to the trapezoidal bracket 2, and both ends of the inner side of the L-shaped limiting plate 404 are fixedly connected to the thrust spring 701, and the end of the thrust spring 701 away from the L-shaped limiting plate 404 is fixedly connected to the outer side of the trapezoidal bracket 2, and a guide hole 703 is opened on the trapezoidal bracket 2, and the inner wall of the guide hole 703 is slidably connected to the guide rod 702, and one end of the guide rod 702 passes through the guide hole 703 and is fixedly connected to the inner side of the L-shaped leaning plate 6, and a vertical array of blocks 811 is distributed on the side wall of the trapezoidal bracket 2;

[0055] When in use: place one end of the door panel 10 on the L-shaped leaning plate 6 and push it inward; the rolling balls 1 602 and 2 604 reduce the contact area between the door panel 10 and the L-shaped leaning plate 6, thereby reducing friction and minimizing damage to the door panel 10 caused by friction.

[0056] When the trapezoidal bracket 2 3 descends and is inserted into the gap between the two adjacent trapezoidal brackets 1 2 below, it may cause squeezing of the thickened door panel 10 placed on the L-shaped inclined plate 6. By setting the thrust spring 701, when the door panel 10 is squeezed, the elastic expansion and contraction of the thrust spring 701 provides it with a certain variable space to avoid damage to the door panel 10 caused by hard squeezing. At the same time, when the trapezoidal bracket 2 3 rises, it contacts the restriction of the door panel 10 on the side wall of the trapezoidal bracket 2. Under the reset thrust of the thrust spring 701, the door panel 10 on the trapezoidal bracket 2 is moved away from the trapezoidal bracket 2, making it easier to grab.

[0057] Example 3: Reference Figures 1-12 , which is basically the same as Example 2. The technical problem in the above solution is that the ball 1 602 and the ball 2 604 are provided to reduce the friction between the door panel 10 and the L-shaped leaning plate 6. However, when the trapezoidal bracket 2 3 is lowered and inserted into the gap between the two adjacent trapezoidal brackets 1 2 below, the door panel 10 placed on the L-shaped leaning plate 6 is squeezed, and another pressure is applied between the door panel 10 and the ball 1 602 and the ball 2 604, which may cause the ball 1 602 and the ball 2 604 to be pressed. 4 leaves marks on the door panel 10, causing damage to the door panel 10. Therefore, further steps are as follows: a ball adjustment structure 8 is provided in the rolling groove 1 601 and the rolling groove 2 603, and the bottoms of the rolling groove 1 601 and the rolling groove 2 603 are both set as open structures; the bottom of the L-shaped limiting plate 404 is opened as an inclined surface 1 804, and a support plate 802 is provided below the inclined surface 1 804. The top surface of the support plate 802 is opened with an inclined surface 2 805, and the side of the inclined surface 2 805 close to the trapezoidal bracket 1 2 is opened with an inclined surface 3 806, as shown in FIG. Figure 12 As shown, if the trapezoidal bracket 2 3 is lowered and inserted into the gap between the two adjacent trapezoidal brackets 1 2 below, squeezing the door panel 10 placed on the L-shaped leaning plate 6, the L-shaped leaning plate 6 will move toward the trapezoidal bracket 2 3, and the bottom of the ball 1 602 will lose its support. The ball 1 602 will move downward along the rolling groove 2 603 and sink into the rolling groove 2 603, causing the door panel 10 to directly contact the bottom of the inner wall of the L-shaped leaning plate 6, thereby preventing the ball 1 602 from directly contacting the door panel 10 under pressure and causing damage.

[0058] Furthermore, the inner wall of the second rolling groove 603 is slidably connected to a support plate 801, the top of the support plate 801 is rollingly connected to the bottom surface of the second ball 604, and the bottom surface of the support plate 801 is connected to a telescopic mechanism;

[0059] The telescopic mechanisms on cargo plate 1 102 and cargo plate 2 103 are connected in series with hydraulic cylinder 1 106 and hydraulic cylinder 2 107 respectively;

[0060] For example, when the door panel 10 is currently being installed on the second pallet 103, the second hydraulic cylinder 107 is controlled to pull the top plate 104 downward, and the telescopic mechanism then drives the support plate 801 and the second ball 604 downward, so that the second ball 604 is immersed in the second rolling groove 603.

[0061] The telescopic mechanism includes: a connecting rod 807, one end of the connecting rod 807 is fixedly connected to the bottom end of the support plate 801, and the other end is fixedly connected to the integrated frame 808, the side of the L-shaped leaning plate 6 close to the trapezoidal bracket 2 is fixedly connected to the U-shaped frame 809, and a hydraulic cylinder three 810 is fixedly installed on the U-shaped frame 809, and the output end of the hydraulic cylinder three 810 passes through the U-shaped frame 809 and is fixedly connected to the integrated frame 808.

[0062] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patented invention. It should be noted that those skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention. These variations and improvements are equivalent modifications and improvements to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
