[0029] like Figure 1-4 As shown, a cantilever servo-controlled sheet metal buffer device provided by the present invention is applied to a CNC sheet metal punching, shearing and folding automated production line, and comprises a conveying unit 1, a transfer unit 2 and a buffer unit 3 which are arranged in sequence.

The conveying frame 101 is welded from rectangular tubes. Adjacent conveying rollers 102 are connected in pairs through roller chains, and can rotate under the action of a first variable frequency motor 103 and a first sprocket system 104, so as to realize plate conveying. A lifting frame 107 is arranged below the conveying rollers 102, and a lifting cylinder 108 is arranged below the lifting frame 107 to drive it to perform lifting movement along a guide shaft 109. A plurality of first synchronous belt pulley systems 113 are arranged above the lifting frame 107, and the first synchronous belt pulley systems 113 are installed on the lifting frame 107 through a first aluminum profile 114 and a first bracket 115, and the first synchronous belt pulley systems 113 are respectively arranged on adjacent conveying rollers 1 02, a second variable frequency motor 105 is arranged on the lifting frame 103, and the second variable frequency motor 105 is connected to the first transmission shaft 110 through the first seat bearing 106, and the first transmission shaft 110 is provided with a plurality of first synchronous wheels 111 respectively connected to the plurality of first synchronous belt pulley systems 113, and a tensioning wheel 112 is also arranged between the first synchronous wheel 111 and the first synchronous belt pulley system 113, so that the first synchronous belt pulley system 113 can rotate under the drive of the second variable frequency motor 105, and further, the conveying direction of the first synchronous belt pulley system 113 is perpendicular to the conveying direction of the conveying roller 102, so as to deliver the plate to the transfer unit 2, and further, a pneumatic lifting guard 116 is also arranged at one end of the conveying frame 101 close to the next process.

[0031] The transfer unit 2 is arranged on one side of the conveying unit 1, and includes a plurality of second synchronous belt wheel trains 209 arranged at intervals. The second synchronous belt wheel trains 209 are used to realize the round-trip transportation of the sheet material between the conveying unit 1 and the buffer unit 3, and there is a buffer space between adjacent second synchronous belt wheel trains 209. Specifically, the second synchronous belt wheel trains 209 are distributed on the transfer frame 202 through the transfer bracket 201, and a third variable frequency motor 205 is arranged on the transfer frame 202. The third variable frequency motor 205 is connected to the second transmission shaft 207 through a second belt seat bearing 206. A plurality of second synchronous wheels 208 respectively connected to the plurality of second synchronous belt wheel trains 209 are arranged on the second transmission shaft 207. In this way, the second synchronous belt wheel train 209 can rotate under the drive of the third variable frequency motor 205, and the conveying direction of the second synchronous belt wheel train 209 is consistent with the conveying direction of the first synchronous belt wheel train 113.

[0032] The cache unit 3 includes a multi-layer cache tube 314 that is arranged corresponding to the cache space and can be lifted and moved. Multiple cache tubes 314 at the same height constitute a cache tube 314 storage layer. The multi-layer cache tube 314 can be connected to the second synchronous belt wheel system 209 with cache tubes 314 of different heights under the action of the driving component, thereby realizing the multi-layer cache function of the sheet material. Specifically, the cache unit 3 includes a cache frame 301 arranged on the side of the transfer unit 2 away from the conveying unit 1, and the multi-layer cache tube 314 is installed on the cache frame 301 The movable bracket 313 can be moved up and down along the vertical guide rail 311 on the cache frame 301 under the action of the driving component. The driving component includes a servo motor 302. The servo motor 302 is connected to the third transmission shaft 306 through a reducer 303. The third transmission shaft 306 is provided with second sprockets 305 at the positions corresponding to the left and right ends of the movable bracket 313. The second sprocket 305 drives the movable bracket 313 to move up and down through the chain 310, thereby driving the multi-layer cache tube 314 to move up and down.

[0033] When a cantilever servo-controlled sheet material caching device of the present invention is used, the sheared sheet material passes through the conveying roller 102 and runs to the pneumatic lifting edge 116 to stop, and the conveying roller 102 stops rotating at the same time. The lifting frame 107 below the conveying roller 102 drives the first synchronous belt wheel system 103 to rise upward under the action of the lifting cylinder 108, and the first synchronous belt wheel system 103 lifts the sheet material on the conveying roller 102. At this time, the idle cache round tube 314 storage layer of the cache unit 3 is switched, and the selected cache round tube 314 storage layer is lifted and lowered to the docking position with the second synchronous belt wheel system 209 by the servo motor 302, and then the second frequency conversion motor 105 driving the first synchronous belt wheel system 113 and the third frequency conversion motor 205 driving the second synchronous belt wheel system 209 work simultaneously, and the sheet material will run along the transmission of the first synchronous belt wheel system 113 and the second synchronous belt wheel system 209 to the cache round tube 314 storage layer corresponding to the cache unit 3 for storage. When the folding machine needs to process the plate, a signal will be given. At this time, the cache tube 314 storage layer of the plate to be taken out is connected with the second synchronous belt wheel system 209, and the lifting frame 107 at the conveying roller 102 drives the first synchronous belt wheel system 113 to the falling position, driving the third frequency conversion motor 205 of the second synchronous belt wheel system 209 to reverse, and the second synchronous belt wheel system 209 transports the plate from the cache tube 314 storage layer and falls on the conveying roller 102 of the conveying unit 1, and can enter the next process under the action of the conveying roller 102.

[0034] To sum up, the cantilever servo-controlled sheet material buffer device provided by the present invention can temporarily store the sheared sheet in the buffer unit, wait for the processing notification of the next process, and then return the sheet from the buffer unit to the conveying unit, which can improve the automation degree and production efficiency of the entire production line, realize batch processing of sheets, and has the advantages of simple structure, stable and reliable, high efficiency, etc.
