Suspended chain, walks wheel, guide rail is formed by deep processing from 16Mn materials, used using ball bearing as chain Life-span is more than 5 years.What chain pitch was commonly used has 150/200/240/250 etc., and single-point load-bearing is also each different.Pass through choosing simultaneously Suspender type is selected, the single-point load-bearing of chain can be increased.The pipeline can arbitrarily turn, climb, and adapt to various geographical environment bars Part.The material distributing in air that the pipeline is used primarily in workshop is served, scheme reasonable in design, can be by phases such as warehouse, assembly lines Artis organically combines, and can make the logistics in workshop in order to the full extent, produces bigger benefit.The pipeline also can As frame of motorcycle portion dress, and spraying equipment drying conveying equipment.
Wired belt conveyer 207:The plastics swivel pin that extends on the whole width of conveyer belt of module net belt, being molded into The guipure of type is assembled into interlocking unit.Such a process increases the intensity of conveyer belt, it is possible to which group is connected into any desired width And length.Baffle plate and side plate can also be interlocked with swivel pin, as one of conveyer belt global facility.
The material of conveyer belt has:Carbon steel, stainless steel, thermoplastic chain, according to different in width, no can be chosen the need for your product The carrier bar of similar shape requires to complete plane conveying, plane turning, lifting, decline etc..
The structure type of wired belt conveyer 207 has:The forms such as horizontal linear conveying, lifting climbing conveying, conveyer belt can be set up Lift baffle plate, side shield.
It may also be noted that power roller-way plate, horse, pull bar, bearing, drive device by power roller tub assembly, aluminium With chain composition.Unpowered roller bed plate, horse, pull bar, bearing by unpowered roller tub assembly, aluminium are constituted.Power roller-way is by driving Dynamic device drives the sprocket wheel on conduction chain, each power roller bucket of chain-driving to rotate, so as to begin with rotationally transportation work.Nothing Power roller-way extrudes workpiece by people's push-and-pull workpiece or workpiece, is moved on roller.
In the present embodiment, the top of conveyer 207 is additionally provided with the pallet 205 for arrangement of goods 206.
In the present embodiment, the conveying direction of the conveyer 207 is to be vertically arranged with the direction of travel of car body 200.
It is pointed out that when car body 200 is run, the operation of the direction along ng a path of car body 200 runs to a certain position needs When unloading, start conveyer 207, unload goods 206 from track side.
As shown in Figure 3-4, the present embodiment provides a kind of walking mechanism of stacking motor spindle, and its drive mechanism uses straight-line electric Machine 100.
Embodiment two
On the basis of embodiment one, the present embodiment provides a kind of automated warehousing logistics system, including described rail Shuttle.
It is pointed out that the automated warehousing logistics system that the present embodiment is provided, it includes described rail shuttle, Therefore its all advantage with rail shuttle, is not just repeated herein.
It may also be noted that the automated warehousing logistics system that the present embodiment is provided, its general configuration is as existing There is technology to be disclosed, just do not repeat herein.
To sum up, the beneficial effects of the utility model are as follows:
First, high-speed response:Because rail shuttle directly eliminates the larger mechanical transmissioning piece of some responsive time constants (such as reductor, chain etc.), greatly improves whole closed-loop control system dynamic response performance, and abnormal reaction is sensitive quick.
2nd, precision:Linear drive system eliminates the drive gap and error due to waiting mechanical mechanism generation, reduces slotting Mend the tracking error come when moving by transmission system hysteresis band.Feedback control is detected by linear position, you can greatly improved The positioning precision of rail shuttle.
3rd, rigidity is high:Due to " direct drive ", it is to avoid because of the elasticity of intermediate transmission link when startup, speed change and commutation The motion delay phenomenon that deformation, fretting wear and backlass are caused, while also improving its transmission stiffness.
4th, speed is fast:In the short rail shuttle straight line moving motion of acceleration and deceleration process, its high speed speed of travel is met (it is required that up to 180~300M/min or higher).High-speed drive active response, greatly shortens its acceleration and deceleration process.To realize Moment is reached at a high speed when dynamic, and energy moment standard is stopped again during high-speed cruising.Higher acceleration can be obtained, it is general up to 2~10g (g= 9.8m/s2), haul distance is unrestricted.
5th, quiet, noise is moved low:Due to eliminating the mechanical friction of the parts such as gearing, noise will when it is moved Substantially reduce.
6th, efficiency high:Due to without intermediate transmission link, eliminating energy loss during mechanical friction, transmission efficiency is significantly Improve.
Finally it should be noted that:Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it System;Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should Understand:It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole Technical characteristic carries out equivalent substitution;And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly The scope of each embodiment technical scheme of type.
