Raise the efficient way of efficiency of crankshaft product line

5h) theory is achievable 562. Grinder of graph 1 OP70, OP80 and Buffer layout however, we are casting postpartum discovery formally, manipulator did not achieve initial design requirement. The Chantaijia of OP70 is versed in cycle time is 68s now, time of the makings on manipulator is 12s, aggregate 80s; Be versed in a total cycle time for 40s; Should be versed in every treatment 10 spare partses need to spend 80s to undertake nap to emery wheel, graph the 2 logistic time that are manipulator. In the discovery when moving actually, manipulator appeared on machine tool and amortize Buffer 2 a few problems: There should be a machine tool to need prune among OP70 grinder emery wheel, there is a part in on-line Buffer 2, there is a spare parts on the Shift Unit above Buffer 2, original manipulator should take expect Shift Unit from Buffer 2 buffer, in order to satisfy the treatment of machine tools of next OP80 of line working procedure. But manipulator did not have this pace action, return the Shift Unit before OP70 machine tool to take however makings, stay in upper part of OP70 machine tool to await machine tool nap to be over emery wheel, send makings hind to the machine tool, arrive again among Buffer 2 buffer take makings the Shift Unit that goes up to Buffer 2, next the manipulator on OP80 takes treatment of expect OP80 grinder from Shift Unit, the working procedure after such meetings are caused lacked a material, influence product line fast. According to everyday 3, 251 weekday will calculate, a class will be little produce 56, reduce production every year at least 3 × of 56 × crankshaft of 251=42 168 root. Manipulator is in of machine tool upper part await a problem to be able to be opposite our yield can cause very big loss. Graph analysis of problem of Nextpage of time of logic of the manipulator before 2 improvement is in the light of manipulator above OP70 the problem that await and do not carry out clear empty Buffer 2 to operate, we undertook comparative careful analysis and contrast to the logistic relation of manipulator. From where does the signal that drives manipulator to produce an action come? Such how many signal is there? What kind of logistic concern do these signal follow? Through dominating the analysis of the program and research to manipulator, we discover the signal that sends manipulator has 3 kinds: A -- the machine tool treatment that finish or the fluctuation makings signal that put forward a spare parts to machine demand; B -- go up from the drawer expect machine tool, need manipulator comes over the signal of capture; C -- the requirement signal that Buffer puts forward buffer of clear empty Buffer. The logic of the signal source that the logistic order of the signal source that the graph sends manipulator 3 kinds 3 sends manipulator 3 kinds according to above is ordinal (see a picture 3) , the first step that we discover the presence of these 3 kinds of signal of manipulator is constant is ordinal: A kind signal preferential, B kind signal next, C kind signal just is satisfied finally. When 3 kinds of signal appear at the same time, when the signal that expects on the demand signal of next makings on the machine tool, drawer namely and clear empty Buffer appear at the same time, manipulator issues the order of signal of the makings on the demand signal of makings and drawer on preferential executive machine tool. Accordingly, manipulator needs the condition of Buffer of clear empty buffer to have the following below automatic circumstance: 1.

Buffer has makings; 2.

Shift Out is not had makings and accepting makings position; 3.

Be being used at sending the Z2 machinery of makings ungual hand must be empty-handed; 4.

In above condition contented circumstance falls, manipulator still needs an additional requirement, do not have A inside 20s namely kind signal and B kind the occurrence of signal, manipulator ability arrives inside Buffer take expect OP80 treatment. In addition, we are transmitted to the signal of manipulator and machine tool also undertook an analysis, discovery has additionally one kind of circumstance to also can cause manipulator to did not carry out C kind the operation of signal, it is OP70 grinder is in be about grinding is over crankshaft when, the machine tool can shift to an earlier date 44s signals to manipulator, ask its give a machine tool to expect up and down, between the empty Yu Shi that the manipulator below the circumstance that works in OP70 only station so has 24s only. This also is to cause manipulator cannot a reason of empty Buffer of crankshaft Qing Dynasty. Integrated above is analysed to the principle of manipulator and machine tool, only when this working procedure a machine tool is machined when, manipulator should spend 44s to await machine tool treatment to finish, 18s is spent to be changed to the machine tool again even later makings, send order of come off work eligible part, manipulator always is maintaining the execution of 62s to command position, and only 6s carries out clear empty Buffer to command. Visible, when OP70 machine tool repairs emery wheel, manipulator cannot execute function of clear empty Buffer. The main reason that creates this appearance has two: 1.

The signal that the machine tool sends manipulator to carry out fluctuation to expect is too early, took up the working hours of manipulator; 2.

The time that 20s of condition of contented clear empty Buffer just starts order of quiet light locomotive trip is too long. Those who transform train of thought and report of proposal above problem to give manipulator logic to go up is unreasonable, we are empty to affecting manipulator Qing Dynasty the main at 2 o'clock reason of Buffer put forward to improve train of thought and solve measure: 1.

Send manipulator to carry out the issue with the too early signal that expects up and down in the light of the machine tool, we think OP70 gives out A kind the timeline that signal gives manipulator is unreasonable. OP70 machine tool shifts to an earlier date 44s gives manipulator signal, cause manipulator to wait to go up in upper part of OP70 machine tool makings, latency time is the longest achieve 51s, manipulator of this paragraph of time can finish C originally kind the command of signal. We adjusted the executive time of manipulator, change manipulator logic, receive the fluctuation that gives out to the machine tool to expect the ability after 26s of the delay time after demand signal is carried out. 2.

The problem with the too long time that just starts order of quiet light locomotive trip in the light of 20s of condition of contented clear empty Buffer, we undertook adjustment to the logistic time of manipulator. Manipulator was not receiving the A that receives OP70 to give out kind the B that signal and drawer give it kind when signal, c is carried out after need awaits 20s again kind signal. Although Buffer has,such meetings are caused makings, manipulator also won't execute the order of amortize of clear empty Buffer. Accordingly, we the conditional time clear empty Buffer by original 20s instead 5s. The test and verify after Nextpage improves we change to what afore-mentioned place do undertook is versed in an effective treatment test and verify: Undertake machining with a machine tool only, additionally 1 does not machine the long emery wheel with imitating a machine tool, there is crankshaft part on Buffer, send expect OP70 the machine tool when manipulator, manipulator can arrive after 5s on Buffer the OP80 machine tool that takes a spare parts to give sequel undertakes machining. Add man-hour at the same time when two, manipulator won't go clear empty Buffer. Through 1 week production observation, improvement of manufacturing moving effect is clear, manufacturing efficiency rises greatly (see a picture 4) , graph 5 for me corporation engine plant produces the spot. Graph the manipulator logic time after 4 improvement pursues although manipulator of conclusion of site of production of 5 engine factory can replace artificial operation, improve labor condition of the worker greatly, put jockey person from the solution in onerous, drab work environment, raise labor to manufacture efficiency. But the thinking of opposite person is logistic, if the logistic time design of manipulator is unreasonable, also can create manufacturing incur loss through delay and waste. Want to find best manufacturing time, the test and verify that need carries out through production and fumble, a few bottleneck that manufacture efficiency to be being affected in production are versed in undertake an analysis, make feasibility plan, realize what crankshaft line produces to produce thereby the can biggest change.
