\u201cChaku\u201d translates as \u201cload\u201d or \u201cinsert\u201d. Using the same word twice \u2013 \u201cChaku-Chaku\u201d \u2013 offers a clue that this particular lean production method<\/a> is based on comparatively simple working processes. All that workers have to do is load a machine, or position a workpiece in it, and move workpieces from one machine to another. The actual processing work and ejection steps are completed in a largely or entirely automated process. All the workstations needed to manufacture a product are located as closely to each other as possible to avoid long distances. This results in lines being arranged in a U or \u03a9 shape, as is the case in the one-piece flow<\/a> method. The worksteps and workstations are arranged in a strict sequence and, often, each member of staff will be able to operate every station. One crucial advantage to the Chaku-Chaku principle is that it introduces flexibility to the system\u2019s output, which means per-person productivity remains consistently high, even if the number of staff is increased. After all, the focus is on ensuring the people \u2013 rather than the stations and machines \u2013 are working to their full capacity. In other words, the machines wait for the people and not the other way around.<\/p>\n<\/div><\/div><\/div><\/div><\/div> As explained above, when work is organized using the Chaku-Chaku method, the actual processing of the work piece happens largely on an automated basis. Frequently, a machine will also eject the processed part itself, too. This is often because suitable ejection devices can be added to a machine relatively cheaply. By contrast, incorporating a device that could load work pieces into a machine with precision would be a very expensive affair. This is why Chaku-Chaku works well in combination with the Hanedashi method. In this method, which equates to automatic unloading, the operator places the work piece into the machine by hand, with the machine processing it and subsequently ejecting<\/a> it. The operator can then pick up the workzpiece and either take it to the next workstation or pass it on to the next operator on the line. While the processed workpiece is being passed on, the machine readies itself for processing the next workzpiece. As a result, operators can complete their work without any distractions and the ergonomics of the assembly workstation<\/a> are enhanced, since staff can avoid the unergonomic movements associated with unloading tasks.<\/p>\n<\/div> When it comes to ejection processes, Karakuri\/LCA (Low Cost Automation)<\/a> \u2013 i.e. automation systems that don\u2019t use drives, sensors, electricity or compressed air \u2013 can be very useful. For instance, Profile Tube System D30<\/a> can be used to create automated applications that rely solely on the laws of gravity and mechanics. If staff following the Chaku-Chaku method are operating several machines in parallel, it is pretty much impossible for them to maintain an overview of everything at the same time. However, lean production has a tried-and-tested solution for this, too \u2013 Jidoka<\/a>. If machines are fitted with monitoring systems that use sensors, for example, they can identify when something has gone wrong and shut themselves down automatically. This is why Jidoka is also referred to as autonomation \u2013 a combination of the words \u201cautomation\u201d and \u201cautonomy\u201d.<\/p>\n<\/div><\/div><\/div><\/div><\/div> Poka-Yoke<\/a>, which translates as \u201cthe avoidance of unfortunate errors\u201d, is another tool that helps operators run multiple machines smoothly under the Chaku-Chaku method. Poka-Yoke utilises mechanisms that either directly avoid mistakes (hard Poka-Yoke) or point out a potential error (soft Poka-Yoke). When using the Chaku-Chaku method, only hard Poka-Yoke is taken into account. For example, imagine a machine that will only start processing a part when that part has been inserted correctly and in a precise position. This means the operator can move straight on to the next machine in the Chaku-Chaku line and will only need to return to the previous one when the Hanedashi mechanism has done its job.<\/p>\n However, Poka-Yoke is not just helpful when the rabbit chase principle<\/a> is being followed, i.e. when every operator needs to have mastered every workstep. Poka-Yoke can also be combined with Chaku-Chaku when the sequence principle is being implemented. In this scenario, operators only take care of certain sequences in the Chaku-Chaku cell and therefore don\u2019t need to take responsibility for every workstep. All the same, no matter which approach is taken, organisation and clarity are absolutely essential because the Chaku-Chaku method is based on processes that have become second nature and high speeds. 5S<\/a> from the visual management<\/a> toolbox is the ideal lean method for delivering these essentials:<\/p>\n Are you interested in fascinating reports and innovations from the world of lean production? .<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":" \u201cChaku\u201d translates as \u201cload\u201d or \u201cinsert\u201d.
