Summary of the invention
Here, the present invention is a background with thing as above, and it solves problem and is to provide a kind of Tufting machine that can mix the neotectonics of the pile fabric that exists with simple structure manufacturing circle suede with the clipping both sides.
Below, be recited as the solution of the present invention that solves above-mentioned problem and finish.In addition, the inscape that is adopted in each scheme of being put down in writing below just can adopt with combination arbitrarily as possible.
Promptly, first scheme of the present invention, a kind of Tufting machine, by referring to that the bar plate supports from face side the base fabric of being carried to a direction by the output roller, simultaneously break-through there is the pin of knitting wool to pierce through this base fabric and thus this knitting wool is pierced through this base fabric from rear side, on the other hand, use makes the throughput direction of free end and this base fabric relative and approaching with respect to this pin, the cover oral area of reciprocal deflection is caught this fine hair that pierces through this base fabric on the direction of leaving, form the knitting wool circle thus, and cut off this knitting wool circle that captures by this cover oral area by cutter with respect to the relative displacement of this cover oral area, it is characterized in that: be provided with and make the indexing application unit of described finger bar plate in the displacement on the direction that described base fabric pierces through of described pin, make this refer to that the displacement of bar plate allows its displacement to the face side of this base fabric by this indexing application unit, can remove the trap state that described knitting wool circle is caught by described cover oral area thus.
In the Tufting machine of making according to this programme, make by indexing application unit to refer to that the bar plate is the displacement of base fabric face side in the direction that pierces through of pin, allow displacement by removing or relax support that the finger bar plate by the base fabric face side carries out to the face side of base fabric.Thus, can relax the tension force that is formed the knitting wool of circle by the seizure of cover oral area in the face side of base fabric, the also actings in conjunction such as displacement of for example overlapping oral area can be removed the trap state of being caught circle by the cover oral area.And the circle of removing from the trap state of being caught by the cover oral area does not cut off by cutter, plants in base fabric with the shape of enclosing suede.On the other hand, when referring to bar plate invariant position,, catch by the cover oral area, keep the trap state of catching thus by the cover oral area with the state that applies tension force to knitting wool with disclosed Tufting machine was same in the past.And the circle of being caught by the cover oral area finally cuts off by cutter and plants in base fabric as clipping.
Like this, in the Tufting machine that is made as according to the structure of this programme, make the position displacement that refers to the bar plate, do not need to change like that the operation of the cover oral area that cover oral area that clipping uses and circle suede uses thus in the past, can form circle suede and clipping selectively by indexing application unit.And, because the replacing that does not need to overlap oral area, can not interrupt forming clipping and circle suede selectively, so can mix the pile fabric that exists with clipping with manufacturing efficient manufacturing circle suede with the machining accuracy of excellence by the conveying operation ground of the base fabric that carries out of output roller.
In addition, circle suede mixes existence with clipping form is mixed the existence with the clipping zone except for example dividing circle suede zone clearly, can adopt various forms such as mixing existence randomly.For example, expansion force that also can be by suitable adjusting base fabric, refer to the bar plate addendum modification, put on the size of the tension force of knitting wool, the displacement direction of cover oral area etc. by the cover oral area, present state that only is formed with circle suede and the state that only is formed with clipping selectively, in addition, also can present circle suede and clipping both sides brokenly.
And then, in the Tufting machine that is made as according to the structure of this programme, structure beyond the indexing application unit that refers to the displacement of bar plate also can be used with the roughly same structure of disclosed cutting machines in the past realize.Thus, can realize to make circle suede mixes the pile fabric that exists with clipping Tufting machine with simple structure.In addition, can obtain to form circle suede mixes the pile fabric of existence with clipping Tufting machine by employed cutting machines since are in the past carried out very little transformation.
In addition, as the concrete structure of the indexing application unit in this programme, can suitably adopt various structures.For example, can support by cylinder mechanism, servomotor and refer to the bar plate and displacement also can be used the pinion and rack displacement, can adopt various forms.In addition, what is called make the direction that refers to the displacement of bar plate be pin pierce through direction to what base fabric pierced through, might not be parallel with the reciprocating direction of pin, as long as be meant the bar plate with respect to the face side of base fabric away from direction.Preferably, to vertical below the surface of base fabric is enclosed and to be planted processing, refer to that at this moment the bar plate is from the supported underneath base fabric.And, refer to that by making the bar plate is vertical or to the displacement of oblique below, base fabric also utilizes gravity effect displacement floppily downwards.
Alternative plan of the present invention is the described Tufting machine of first scheme as described, it is characterized in that: the rotating shaft that is extended on width by the face side that can make described finger bar plate be centered around described base fabric back and forth rotates the rotating mechanism of displacement and regulates this rotation amount governor motion that refers to the reciprocal rotation addendum modification of bar plate that is undertaken by this rotating mechanism and constitutes described indexing application unit.More particularly, as one of this alternative plan, shown in third party's case of the present invention, can preferably adopt following proposal: constitute described rotating mechanism by linkage, and constitute described rotation amount governor motion by cylinder mechanism.
So, can constitute indexing application unit with simple structure.As the cylinder mechanism in third party's case, can suitably adopt well-known cylinder such as cylinder, hydraulic cylinder mechanism here.In addition,, and only limit to cylinder mechanism like that not as third party's case, for example also can use servomotor etc. as the rotation amount governor motion in the alternative plan.
Cubic case of the present invention is first any described Tufting machine to third party's case as described, it is characterized in that: described finger bar plate is made as segmenting structure on the width of described base fabric, this bar plate of cutting apart that respectively refers to is provided with described indexing application unit respectively, make thus these respectively refer to the bar plate can be respectively in the displacement on the direction of piercing through of described pin.
In the Tufting machine that is made as according to the structure of this programme, by making the displacement respectively on the width of base fabric of a plurality of finger bar plates, not only can on the throughput direction of base fabric, make circle suede mix existence with clipping, and can with the width of throughput direction quadrature on make and enclose suede and mix existence with clipping.Thus, circle suede and clipping alternately can be formed reticulate pattern on the width of base fabric, and then be controlled to be more high accuracy by the displacement that each is referred to the bar plate, this pattern that can form clipping or circle suede on the incline direction of base fabric is continuously arranged, so can form more complicated or various pattern.
Promptly, can set the displacement that respectively refers to the bar plate independently of each other to the direction of separating with respect to base fabric, so can for example only form clipping, only make clipping mix existence brokenly at specific region formation circle suede or in the specific region with circle suede in the specific region, and then the zone of mixing existence at clipping and circle suede brokenly also can make the clipping and the relative scale of circle suede change.And, be on the throughput direction not only at base fabric, on width, also can be divided into referring to cutting apart of bar plate and count corresponding zone, carry out so various settings respectively.
In addition, in the time will referring to be made as segmenting structure on the width of bar plate at base fabric,, also can be set as segmenting structure for each and the corresponding part of these divided finger bar plates for for example overlapping oral area.Thus, the conditions such as tension force that put on circle by the cover oral area also can refer to the setting of bar plate to each separation, can carry out aforesaid clipping and the selectable formation of enclosing suede more accurately.
