Its main use is: In the top shelf of the warehouse in orbit, will be located at the mouth of the goods in goods mesh; Or the opposite, take out loans in case the goods to the mouth of roadway, the loading and unloading finish homework. 2 O the early 70 s, China began to research the type of machine of roadway when the three-dimensional warehouse, according to not complete count, up to now has been built more than three hundred seats. Stacking machine as a three-dimensional storehouse of the most important lifting transportation equipment, also obtained fast development. 2 version of the present situation of stacking crane technology. According to the current machinery industry standard, the position of the stacking crane classification of ways. E.g. by supporting mode, use, the method of control, structure, operation such as classified track. But no matter what type of stacking machine, is general by the mobile mechanism, level of lifting mechanism, manifest Taiwan and goods fork institutions, frame and electrical equipment, and other basic parts. In the present application of three-dimensional warehouse, stacking machine is the most common in the form of the structure and operation track classification. 2.1 version of the good way of spider crane structure From the structure form difference at present in the warehouse stacker has a double set on structure and single pillar structure. double pillar stacker. Double post the stacker frame structure by two root made on the beams, and to form a rectangle beam under the framework. Pillar form well pipe and pipe. Square tube and be lifting guide rail, pipe additional hoisting guide double pillar stacker the biggest advantage is the strength and the brush sex are quite good, and smooth operation. General for lifting height, weight and higher up large speed high level of three-dimensional storehouse stacker, many with double pillar structure, double pillar stackers lifting mechanism, widespread use of the chain transmission, by motor reducer drive sprockets rotation, through the chain traction machine parts made on or along the hoisting guide for lifting movement. Due to the chain transmission used more closed chain or balance by empty asked size limit device, transmission and decorate a complicated. But positioning precision. single pillar stacker. Single pillar of stacker frame structure by a root of the pillar and beam. Pillar used more larger h-beam or welding production, pillar additional guide. The weight of the lighter, consume little material, so manufacturing relatively low cost, but the rigid is a bit poor. Because parts of Taiwan and the goods on the eccentricity of the opposite effect, and walk, the braking force level from the effect, make single pillar stacker in used on have limitations. Not suitable for lifting weight and the running speed of the high level of stacking machine. Single pillar stackers hoisting structure, the widespread use of the wire rope transmission, by motor reducer drive drum rotating, through the wire rope traction machine parts made on or along the lifting rails for lifting movement. For wire rope transmission, transmission and decorate relatively easy, but positioning accuracy is a bit poor. Version of stacking crane to track the performance Stacker level drive general installation in stacker next beam, through the electricity Machine speed reducer drive wheel rotation, make stacker level concerning the direction. This ground driving way most common use. General use two bearing wheel, and along the laying on the ground track (usually also called to rail) operation. Through the bottom two groups of level round orbit direction, the top two groups in stacker guide wheel along in orbit (usually also called day rail) operation auxiliary oriented. According to the running track form difference, there is a straight line type stacker and curve operation type stacking machine. L straight lines type stacking machine. Straight line type stacker can only be in the roadway straight orbit, unable to convert roadways. Only through the other transportation equipment of transformation, such as stacker car transport. Straight line type stacker can realize the operation, and can satisfy the loading and unloading higher frequency three-dimensional storehouse homework, most widely used. curve operation type stacking machine. Curve operation type stacking locomotive wheels and the beam under the vertical axis of the hinged, can be in the ring or other curve orbit, can go curve, not through the other transportation equipment can then from a roadway to transfer to another roadways. Such stacker usually also called transition stacker. Curve operation type stacker in used on have limitations, only applies to the loading and unloading frequency low three-dimensional storehouse. Because not only by the turning radius to the limit, and turning special slow speed, and can't meet the person library of frequency and high warehouse operation. The position of the roadway stacking crane development trend. Along with the development of modern industrial production, stacking crane technology of version continuously improved and perfected. The world's major industrial countries starting point on the development of new products and reliable performance and high on the operation on pay more attention to the practicality and safety. In stacker, we shall see and world advanced nation gap, summarizing the experience find out the deficiency, break traditional ideas, has introduced new appearance and higher performance stacker. In make stacking machine has higher precision at the same time, increase speed to get shorter operation cycle and more production ability. Believe that, through our continuous efforts more high speed, safe and reliable heap when the machine will continue to digest imported from abroad domestic, make the position of stacking crane development roadway to an update to the stage.
