Patent document 1: Japanese Unexamined Patent Publication 2009-160084 publication
Patent document 2: Japanese Unexamined Patent Publication 2004-105392 publication
Patent document 3: Japanese Unexamined Patent Publication 2006-167069 publication
But, in the operation analysis apparatus of so existing Sewing machines, there is following problem.
(1) activity duration determined by Sewing machines cannot be categorized as " periodic time " and " irregular activity duration " by the operation analysis apparatus of the Sewing machines recorded in patent document 1.
Making operation and using the activity duration needed for stopwatch measurement fabricated product the side of operator viewing operator, obtains its mean value.Owing to carrying out this measurement operation to all operations person, so take extremely many Measuring Time.
(2) the production management device of the Sewing machines recorded in patent document 2 is identical with the operation analysis apparatus of the Sewing machines recorded in patent document 1, cannot distinguish the periodic of " take, make, place " sewing object etc. and irregular operation.
In addition, the content of the periodic of " take, make, place " etc. cannot certainly also be distinguished.If consider " take, make, place " in further detail, then " to take " and activity duration (" picking and placeing operation " time) of " placement " is subject to the impact of the laying method of material or the configuration of Sewing machines etc.On the other hand, the activity duration (" making operation " time) of " making " is easily subject to the impact of making the difficulty of operation that the technical ability of operator or the material of sewn object or shape cause.
In order to improve productivity to shorten the activity duration time, different with the process of the improvement that " making operation " adopts to " picking and placeing operation ".
The production management device of the Sewing machines recorded in patent document 2 only cannot distinguish the time of " making operation " in periodic.Therefore, existence cannot determine inefficient reason in detail, cannot find the problem of the main points that operation improves.
(3) Recoring device of the Sewing machines recorded in patent document 3 can record the action of " take, make, place ", but there is the problem that cannot judge the deviation of activity duration.
Usually, " making operation " is the operation of the impact of the technical ability being subject to operator, and it is the less operation of the deviation of activity duration.
Make the activity duration upper reason producing deviation as this, can consider: (1) operator does not carry out suitable operation; And (2) result from the material of sewing object or the difficulty of making operation of shape, the fluffing/bending material that waits namely due to material is unstable, causes the difficulty etc. of making operation.
Like this, ameliorative way is different because of operation, so need to classify to operation and clear and definite where existing problems.
The job class of operator is only main operation (Sewing machines carries out the time of action) and operation in addition by the operation analysis apparatus of existing Sewing machines, cannot be applied to suitable improvement activity.
