Description

Technical Field

[0001] The utility model relates to the technical field of metal material warehousing, and particularly relates to an intelligent three-dimensional storage library for accessing and storing plates. Background Art

[0002] In the fields of manufacturing various metal material structures, management operations such as steel procurement, inventory, and issuing for use are indispensable.

[0003] For metal structures of steel plates, since the materials used generally have various materials and specifications, and the sizes of the steel plates are relatively large, there is not enough space to place them separately during storage. They can only be stacked according to the actual loading situation of the transport vehicles, resulting in the mixed stacking of materials of various materials and specifications. Even if a preliminary classification is carried out during warehousing and basic identification signs are established for subsequent searching and issuing and reduction of inventory, it still requires a large amount of labor and time, and it is also impossible to stack them in the order of production. When put into production, it is necessary to selectively issue and put them into production according to the process requirements. Therefore, when issuing, it is necessary to search and issue according to the production requirements. In the case of mixed stacking of materials, a large amount of material turning work must be carried out, with a huge workload, more time-consuming, and poor operation safety. When issuing for subsequent production, the search is repeated again, wasting a large amount of manpower and material resources, with extremely low work efficiency. If there is an error in the search during issuing, it will also lead to material scrapping.

[0004] In addition, if the materials are stacked in a covered warehouse, although they can be effectively protected during storage, it will occupy a large amount of workshop or special warehouse; if the materials are stacked in an open-air warehouse, it will cause material rust (severely rusted materials will also be scrapped), and rust removal treatment must be carried out for subsequent processing, which will increase production costs, lengthen the turnover time, and reduce production efficiency, forming a vicious cycle.

[0005] Therefore, it is very necessary to adopt a new and efficient material inventory method to achieve the management operation purposes of less site occupation, safe storage, clear search, and efficient issuing for production. Content of the Utility Model

To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.

[0053] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0054] See also Figures 1 to 6 As shown, the utility model provides an intelligent plate storage and retrieval stereoscopic warehouse, comprising:

[0055] The three-dimensional storage unit 100 is erected on the ground and has a multi-layer storage platform for storing boards 400 of different specifications in layers;

[0056] A lifting and feeding unit 200 is lifted and connected to the front side of the three-dimensional storage unit 100, and has a feeding platform for feeding plates to achieve storage and retrieval; and

[0057] An intelligent control unit 300 is used to control the first two units to work in coordination;

[0058] Among them, when the feeding platform is flush with one of the storage platforms, the storage platform on that layer will run synchronously and at the same speed as the feeding platform.

[0059] Specifically, the three-dimensional storage unit 100 includes a shelf 110 with a rectangular structure, and a multi-layer storage platform is arranged in the shelf 110 at an equal height; each storage platform includes at least three first support shafts 120 arranged in parallel and rotatably connected to the shelf 110, one end of which is connected to a first motor 130, and the first motor 130 is fixedly installed on the shelf 110; a plurality of first sprockets 121 are arranged at equal intervals on each first support shaft 120, and the first sprockets 121 at the same position on the plurality of first support shafts 120 are connected to each other through a pair of first covered chains 122 (see for details). Figure 6 As shown). That is, the first covered chain 122 is movably mounted around the first sprocket 121 at the same position of multiple first support shafts 120, forming a storage platform on each layer of the shelf to transport and store the plates. Each storage platform is provided with a first motor 130, and the multi-layer storage platforms operate independently of each other and do not interfere with each other. The first motor 130 drives the first support shaft 120 to perform forward or reverse rotation under the command of the control signal, driving the first covered chain 122 and the plates stored thereon to enter and exit the shelf, thereby realizing automatic storage or use of the plates in the warehouse.

[0060] The shelf 110 includes a pair of front columns 111, a pair of rear columns 112 and at least a pair of middle columns 113. The first support shaft 120 is rotatably connected between the pair of front columns 111, the pair of rear columns 112 and the pair of middle columns 113 respectively through bearings. The first motor 130 is fixedly installed on a rear column 112, and its output shaft is connected to one end of the first support shaft 120 through a coupling. Specifically, the front columns 111, the rear columns 112 and the middle columns 113 are made of H-shaped steel, and they are welded and connected into a three-dimensional frame through a number of rectangular tubes arranged horizontally and vertically. In order to strengthen the overall structure, a number of vertical rectangular tubes are also arranged between the front columns 111 and between the rear columns 112 to be used as secondary columns. If it is used outdoors, fixed or movable rain shields can be installed on the five sides (except the bottom surface) of the shelf 110 to protect the metal plates from rusting due to sun and rain.

[0061] See Figure 4 As shown, a vertical guide rail 114 is connected to the front side of each front column 111, and a vertical rack 115 is fixedly connected to one side of the vertical guide rail 114. The lifting and conveying unit 200 includes a lifting frame 210, and the lifting frame 210 has a pair of lifting columns 211 and a longitudinal beam 212 vertically connected between the lower ends of the pair of lifting columns 211. The lifting columns 211 are slidably matched with the vertical guide rail 114, and a lifting motor 213 is fixedly installed at each end of the longitudinal beam 212. A lifting gear 214 is fixedly connected to the output shaft of the lifting motor 213, and the lifting gear 214 meshes with the vertical rack 115. The lifting motor 213 drives the lifting gear 214 to rotate forward and backward under the command of a control signal, so as to drive the lifting and conveying unit 200 to move precisely up and down along the height direction on the front columns 111 of the shelf 110, and precisely lift the plate to the storage platform at the corresponding height of the three-dimensional storage unit 100.

[0062] A pair of traveling wheels 215 are rotatably connected to each lifting column 211, and the traveling wheels 215 are in rolling cooperation with the vertical guide rail 114. Specifically, the traveling wheels 215 are movably installed on the lifting column 211 through a pin shaft, and their treads are in positive contact with the front surface of the vertical guide rail 114 and slide on the vertical guide rail 114 in a rolling manner. That is to say, replacing the sliding between the lifting column 211 and the vertical guide rail 114 with the rolling of the traveling wheels 215 can greatly reduce the frictional resistance during the up and down movement of the lifting and conveying unit 200 along the vertical guide rail 114.

[0063] A plurality of brackets 216 are connected to one side of each lifting column 211 facing the vertical guide rail 114, and each bracket 216 is rotatably connected to a limiting wheel 217, and the limiting wheel 217 is in rolling cooperation with the other side of the vertical guide rail 114. Specifically, the limiting wheel 217 is movably mounted on the bracket 216 through a pin, and the tread of the limiting wheel 217 keeps in contact with the back of the tread of the vertical guide rail 114, and can roll and slide on the contact surface. That is to say, the overturning constraint of the lifting and feeding unit 200 can be realized through the limiting wheel 217, so as to ensure that the lifting and feeding unit 200 is always in a relative posture with the three-dimensional storage unit 100.

[0064] See also Figure 5 As shown, the feeding platform is arranged in the lifting frame 210, and the feeding platform includes three second support shafts 220 arranged in parallel and rotatably connected to the lifting frame 210, one end of which is connected to a second motor 230, and the second motor 230 is fixedly installed on the lifting frame 210; a plurality of second sprockets 221 corresponding to the first sprocket 121 are arranged at equal intervals on each second support shaft 220, and the second sprockets 221 at the same position on the plurality of second support shafts 220 are connected by a pair of second covered chains 222. Specifically, the second covered chain 222 is movably mounted on the second sprockets 221 at the same position of the plurality of second support shafts 220, forming a feeding platform of the lifting feeding unit 200 to transport the plate. The second motor 230 drives the second support shaft 220 to perform forward or reverse rotation under the command of the control signal, drives the second covered chain 222 and the plate stored thereon to enter and exit the lifting feeding unit 200, thereby realizing the function of the plate automatically entering and exiting the three-dimensional storage unit 100.

[0065] In this embodiment, the first sprocket 121 and the second sprocket 221 are both double-row sprockets; the first covered chain 122 and the second covered chain 222 are both double-row covered chains.

[0066] The lifting frame 210 includes a pair of end beams 218, one end of which is vertically connected to the lower end of the lifting column 211 and is perpendicular to the longitudinal beam 212 (i.e., the angle is 90°); the second support shaft 220 is rotatably connected between the pair of end beams 218 through bearings; the second motor 230 is fixedly installed on one end beam 218, and its output shaft is connected to one end of the second support shaft 220 through a coupling. Specifically, the lifting column 211, the longitudinal beam 212 and the end beam 218 are welded to each other to form a platform frame. A diagonal brace 219 is also welded between the upper end of the lifting column 211 and the other end of the end beam 218 to form a triangular support, which is used to strengthen the rigidity and stability between the lifting column 211 and the platform frame.

[0067] The intelligent control unit 300 includes a computer 310 with a built-in control program, a handheld laser coder, and a signal display light installed on each storage platform (not shown in the figure); the computer 310 is fixedly installed on the shelf 110, and is used to control the start and stop of the first motor 130, the lifting motor 213, and the second motor 230; the handheld laser coder and the signal display light are electrically connected to the computer 310, the handheld laser coder is used to laser code the plate, and the signal display light is used to display the stock status of each storage platform. Specifically, the computer 310 has the ability to perform programmed automatic operation and manual operation, receive / send and process information and instructions transmitted by the information system, automatically search and analyze whether there is material or no material on each storage platform of the three-dimensional storage unit 100, automatically plan the incoming plates to enter any storage platform without material on any layer for storage and record, and automatically search for the location of the required outbound plates and issue outbound operation instructions.

[0068] The working principle (steps) of the utility model are as follows:
