ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an automatic cutting and solder-less connection apparatus, wherein a covered electric wire rolled and coiled in a wire reel is intermittently uncoiled from the wire reel and being cut by a cutter into a predetermined length; each ends of the predetermined length cut wire is stripped in such a manner that a covered portion of the covered wire is removed from the end of the predetermined length cut wire and that a core wire in the predetermined length cut wire is disclosed; the disclosed core wire is fit into a terminal; and the terminal is made with solder-less connection so as to combining the terminal and the core wire. The present invention relates specifically to an automatic cutting and solder-less connection apparatus, wherein since a belt conveyor unit is controlled to drive corresponding to the variable length of a product to be produced, previous reduction of emergency stop case of the apparatus, previous reduction of no good products causing case and low consumption of electric power are able to be proceeded, even though the length of a product to be produced is variable.
2. Description of the Related Art
A general automatic cutting and crimping apparatus is known by an official gazette, Japanese Patent Application Laid-Open No. 6-96630. The general automatic cutting and crimping apparatus is the construction that covered electric wire is intermittently fed from the wire reel and being cut by a cutter and that each ends of the predetermined length cut wire is stripped in such a manner that a covered portion of the covered wire is removed from the end of the predetermined length cut wire and that a core wire disclosed is fit into a terminal by crimping so as to combining the terminal and core wire.
In the general automatic cutting and crimping apparatus, in case to produce a product having a length excess, for example 50 cm, when an electric wire is fed out with the length of the product to be produced, the fed out portion of the electric wire is jammed against any unit located around the feeder unit, thereby causing emergency stop of the apparatus and causing no good products. Therefore, the fed out portion of the electric wire is required to be restricted from curing or other deforming by any method.
In this connection, an improved apparatus includes a transferring conveyor which is full-time driven to transfer the fed out portion of the electric wire toward the down-stream direction.
According to the general automatic cutting and crimping apparatus, even though the length of a product to be produced is comparatively large, the fed out portion of the electric wire is not jammed against any unit located around the feeder unit, thereby avoiding to cause emergency stop of the apparatus and to cause no good products.
However, since the general automatic cutting and crimping apparatus described above full-time transfers the fed out portion of the electric wire toward the down-stream direction notwithstanding whether the length of a product to be produced is large or small, it is difficult to save consumption of electric power during operation.
Therefore, it is necessary to further improve an apparatus wherein previous reduction of emergency stop case of the apparatus previous reduction of no good products causing case and low consumption of electric power are able to be proceeded, even though the length of a product to be produced is variable.
SUMMARY OF THE INVENTION
The present invention has been achieved with such points in mind.
It is therefore is an object of the present invention to provide an automatic cutting and solder-less connection apparatus, wherein since a belt conveyor unit is controlled to drive corresponding to the variable length of a product to be produced, previous reduction of emergency stop case of the apparatus, previous reduction of no good products causing case and low consumption of electric power are able to be proceeded, even though the length of a product to be produced is variable.
To achieve the object, according to a first aspect of the present invention, there is provided an automatic cutting and solder-less connection apparatus, comprising: a length measuring unit intermittently feeding a covered electric wire; a cutting a stripping unit cutting the covered electric wire into a predetermined length, the cutting and stripping unit stripping in such a manner that a covered portion of the covered wire is removed from the end of the predetermined length cut wire; and end-treating unit connecting a core wire disclosed by removing the covered portion with a terminal; a conveyor unit transferring the covered electric wire from the down-stream of the covered electric wire toward the up-stream of the covered electric wire; a center process unit deciding whether a length of a product to be produced is in excess of an appropriate length which is previously determined; and a drive control unit controlling the conveyor unit to dive according to the result of the decision by the center process unit.
In the automatic cutting and solder-less connection apparatus, depending upon the result that the conveyor unit is controlled to drive corresponding to the variable length of a product to be produced, previous reduction of emergency stop case of the apparatus, previous reduction of no good products causing case and low consumption of electric power are able to be proceeded, even though the length of a product to be produced is variable.
According to a second aspect of the present invention as it depends from the first aspect, there is provided an automatic cutting and solder-less connection apparatus, wherein the drive control unit controls the conveyor unit to dive according to the result of the decision by the center process unit where the length of a product to be produced is in excess of the appropriate length; and the drive control unit controls the conveyor unit to stop the dive according to the result of the decision by the center process unit where the length of a product to be produced is not in excess of the appropriate length.
In this apparatus, according to the control depending upon the variable length of a product to be produced, previous reduction of emergency stop case of the apparatus, previous reduction of no good products causing case and low consumption of electric power are able to be proceeded, even though the length of a product to be produced is variable.
According to a third aspect of the present invention as it depends from the first or the second aspect, there is provided an automatic cutting and solder-less connection apparatus, wherein the conveyor unit transfers the up-stream portion of the electric wire in a direction where the length measuring unit feeds the covered electric wire in such a manner that the electric wire is kept substantially straight.
By the apparatus according to the third aspect of the invention, the up-stream portion of the electric wire is transferred in the same direction where the length measuring unit feeds the covered electric wire, not in reverse direction. Therefore, the same result as by the first aspect is gained.
According to a fourth aspect of the present invention as it depends from the one aspect among the first aspect to the third aspect, there is provided an automatic cutting and solder-less connection apparatus, wherein a transferring speed by the conveyor unit is set the same speed or excess speed of the covered electric wire fed by the length measuring unit.
In this apparatus, since the up-stream portion of the electric wire is transferred at the appropriate speed, the same result as by the first aspect is gained.
According to a fifth aspect of the present invention as it depends from the one aspect among the first aspect to the fourth aspect, there is provided an automatic cutting and solder-less connection apparatus, wherein the length of a product to be produced is determined by process data including substantial data in relation to the product to be produced.
In the apparatus according to the fifth
