Description




TECHNICAL FIELD




The present invention relates to a needle selector for a knitting machine and, more particularly, to a needle selection finger formed by combining a plurality of members, and a needle selector for a knitting machine which uses it.




BACKGROUND ART




In a knitting machine such as a circular knitting machine or weft knitting machine, vertical motions of the working needle are selected on the basis of a knitting procedure stored in a storage such as a floppy disk, to knit a fabric of a desired knit texture. Various types of needle selectors are used for selecting the vertical motions of the working needle.




Before describing the needle selector according to the present invention, the outline of needle selection in a knitting machine will be explained with reference to a circular knitting machine schematically illustrated in

FIGS. 4A

to


4


C.





FIG. 4A

is a schematic perspective view for explaining the basic knitting mechanism of a circular knitting machine. As illustrated in

FIG. 4A

, the circular knitting machine has a knitting cylinder


1


rotatable in the direction indicated by an arrow A. A plurality of vertical grooves (not shown) are formed in the outer surface of the knitting cylinder


1


along its longitudinal axis. Working needles


2


are arranged slidably in the vertical grooves. Usually, needle selection jacks


12


are arranged under the working needles


2


to be able to abut against the lower parts of the working needles


2


. A cylinder-shaped cam base


15




a


is stationarily arranged under the knitting cylinder


1


. A plurality of raising cams


15


with predetermined shapes are arranged on the upper part of the cam base


15




a


at predetermined intervals.




The basic principle of knitting will be briefly described. When each working needle


2


on the rotating knitting cylinder


1


is thrust upward by the corresponding raising cam


15


through the needle selection jack


12


, it projects from the upper surface of the knitting cylinder


1


. A yarn


5


fed from a yarn bobbin


6


is supplied to the hook of the projecting working needle


2


, thus forming a yarn loop. Then, the working needle


2


is lowered by a known mechanism (not shown), so one stitch is formed. Therefore, control operation of forming a stitch by selecting whether vertical motion is to be applied to the working needle


2


, or allowing advance to the next knitting step without forming a stitch can be performed. As a result, a desired fabric can be knitted. In order to provide such motions to the working needles, in the knitting machine, the needle selection jacks


12


are usually arranged in contact with the lower parts of the working needles


2


. The vertical motions of the working needles are controlled, by selectively engaging the needle selection jacks


12


and raising cams


15


, by using a needle selector


3


, operating on the basis of information from a controller


4


with a built-in storage that stores a knitting procedure.




Next, a case wherein piezoelectric bodies are used as needle selection means will be described with reference to

FIGS. 4B and 4C

which show the relationship among the working needles


2


, needle selection jacks


12


, and needle selector


3


.

FIGS. 4B and 4C

are schematic views that facilitate understanding of the operation of the needle selection means with ease.




A piezoelectric body


7


can be either curved as shown in

FIG. 4B

, or curved as shown in

FIG. 4C

, in the direction opposite to that shown in

FIG. 4B

, depending on how a voltage is applied to it. A finger


9


is arranged at the tip of the piezoelectric body


7


to be linked to it. In

FIGS. 4B and 4C

, the piezoelectric body


7


, finger


9


, and raising cam


15


are positioned within the surface of the drawing, and the working needle


2


and needle selection jack


12


move circularly together with the knitting cylinder


1


(not shown) from the top to the bottom of the surface of the drawing (or in the reverse direction). The needle selection jack


12


can swing about a fulcrum


12




a


as the center. A needle selection butt


13


(upper part) and raising cam butt


14


(lower part) project sideways from the needle selection jack


12


as shown in

FIGS. 4B and 4C

.




When the piezoelectric body


7


is curved as shown in

FIG. 4B

, the needle selection butt


13


of the needle selection jack


12


which moves circularly hits the finger


9


. As a result, the needle selection jack


12


is thrust clockwise about the fulcrum


12




a


as the center, and the raising cam butt


14


of the needle selection jack


12


cannot engage with the raising cam


15


. Therefore, the needle selection jack


12


is not thrust upward by the raising cam


15


, and accordingly the working needle


2


is not thrust upward.




When the piezoelectric body


7


is curved as shown in

FIG. 4C

, the finger


9


at its tip does not hit the needle selection butt


13


of the needle selection jack


12


which moves circularly together with the knitting cylinder


1


. Hence, the needle selection jack


12


remains in the vertical direction, and accordingly the raising cam butt


14


at the lower end of the needle selection jack


12


engages with the raising cam


15


. Therefore, the needle selection jack


12


is thrust upward along the inclined surface of the raising cam


15


, and accordingly the working needle


2


is also thrust upward.




A member indicated by reference numeral


25


in

FIGS. 4B and 4C

is a finger pivot stopper formed by part of the frame of the needle selector. When the position of the member


25


is appropriately determined, the finger


9


engages with the needle selection butt


13


reliably, so the finger


9


is prevented from drifting over contact with the needle selection butt


13


.




In this manner, selective engagement of the needle selection butt


13


of the needle selection jack


12


with the finger


9


at the tip of the piezoelectric body


7


enables the working needle


2


to move upward freely as desired and thereby enables a knit fabric of any desired knit texture to be knit.





FIG. 5

shows the relationship between the piezoelectric body


7


and finger


9


of this piezoelectric needle selector


3


.




As shown in

FIG. 5

, the finger


9


is arranged to be movable relative to the piezoelectric body


7


having a bimorph piezoelectric element. Power is applied to the piezoelectric body


7


to actuate the finger


9


. This motion of the finger


9


causes the working needles of the knitting machine to be selected (more specifically, via the needle selection jack


12


), and knitting of a fabric with a predetermined knit texture is made possible. The rear end of the piezoelectric body


7


is movably supported via a spherical body, i.e., a rotary body


20


, by a support


21


or a concave part


22


of a housing. The tip of the piezoelectric body


7


is movably linked via a rotary body


16


into a U-shaped groove


17


(to be referred to as a slit


17


hereinafter) at the rear end of the finger


9


. The piezoelectric body


7


is arranged with its predetermined position between the rear end and the tip of the piezoelectric body


7


being pinched by a rotary body


23


rotatably fitted to a support


24


or the housing.




As shown in

FIG. 5

, the finger


9


is supported at its intermediate portion


9




b


by a support


10




b


through a pin


18


. Hence, when the piezoelectric body


7


flexes, its motion vertically moves a rear end (piezoelectric body engaging portion)


9




a


of the finger


9


. As a result, the finger


9


swings about the pin


18


, serving as the pivot support point of the finger


9


, as the center, so a bar-shaped portion


9


C of the finger


9


projecting through an opening


11


of a support


10




a


swings, and consequently a tip


9




d


moves vertically. The vertical motion of the tip


9




d


causes the rising motion of the working needle


2


described above to be selected.





FIG. 6A

is a side view of a conventionally known finger


9


, and

FIG. 6B

is a front view of the same. As shown in

FIGS. 6A and 6B

, the finger


9


is comprised of a bar-shaped thin elongated member


9




c


extending from a butt abutting surface


9




d


at its tip to reach a central portion


9




b


having a pivot support point


18




a


, and a piezoelectric body engaging portion


9




a


extending from the central portion


9




b


in the other direction. The pivot support point


18




a


is on a longitudinal axis 9X


1


of the bar-like thin elongated member. The piezoelectric body engaging portion


9




a


has a slit


17


to accommodate a curved motion end


16


of the piezoelectric body.




As shown in

FIGS. 6A and 6B

, the conventionally known finger


9


is formed of a material, integral from its butt abutting surface


9




d


on the knitting cylinder-side tip to the piezoelectric body engaging portion


9




a


of the needle selector.




The shape, size, and the like of the finger


9


, however, change depending on the type of the knitting machine, the type of the needle selector, and the knit texture of the fabric to be knitted by this knitting machine. The manufacturer of the needle selector for the knitting machine copes with this situation by preparing very many types of fingers in stock.




In view of this, it has been discussed to form a predetermined finger in the following manner. The operatively downstream portions (to be referred to as finger members in the following description) of fingers which have butt abutting surfaces engageable with the needle selection jacks of the knitting cylinder and the operatively upstream portions (to be referred to as finger holding members in the following description) of the fingers which have the piezoelectric body engaging portions for the needle selector are fabricated by separate manufacturing steps, and are kept in stock. A finger holding member and finger member are appropriately selected and combined in accordance with the type of the knitting machine in which the finger is to be used, and with the knit texture of the target fabric, thus forming the predetermined finger. This can greatly reduce the number of the types of fingers to be kept in stock.




A finger (to be referred to as a module finger hereinafter) which is formed by combining a finger holding member and finger member to match the object is recently known. An example of the module finger will be described hereinafter with reference to

FIGS. 7A and 7B

showing perspective views.




A module finger


30




a


shown in

FIG. 7A

is comprised of a finger member


31




a


and finger holding member


40




a


. The finger member


31




a


is comprised of a butt abutting portion


33




a


having a butt abutting surface


32




a


at its tip, and a support


34




a


extending like a bar from the butt abutting portion


33




a


. The finger holding member


40




a


has a metal plate slit


44




a


at its lower part to form a piezoelectric body engaging portion


45




a


. A connecting plate


46


is connected to the upper side of the slit


44




a.






The finger member


31




a


and finger holding member


40




a


of the module finger


30




a


shown in

FIG. 7A

are connected using a synthetic resin after the lower part of the support


34




a


of the finger member


31




a


and the connecting plate


46


above the finger holding member


40




a


are manually arranged to oppose each other. Namely, a connecting portion


51


is formed from the synthetic resin.




The module finger


30




a


obtained with this method cannot be used for high-speed rotation, since the positional relationship between the butt abutting surface


32




a


and piezoelectric body engaging portion


45




a


is low. Furthermore, the complicated manual operation using the synthetic resin increases the cost.




A module finger


30




b


shown in

FIG. 7B

is comprised of a metal finger member


31




b


substantially identical with the finger member


31




a


shown in

FIG. 7A

, and a synthetic resin finger holding member


40




b


. The module finger shown in

FIG. 7B

is manufactured in the following manner. More specifically, first, the finger member


31




b


is manufactured with high precision by using a metal material, and is kept in stock. When fabricating a specific module finger


30




b


, a finger member


31




b


with a structure suitable for the knit texture of the fabric is selected. A mold corresponding to the structure of the target finger holding member


40




b


is loaded in an injection molder, and the finger member


31




b


is arranged at a predetermined position in the mold of the injection molder. Then, a synthetic resin is injected.




The module finger


30




b


shown in

FIG. 7B

, which is obtained in accordance with the above method, has excellent size precision. Regarding the manufacture of the module finger


30




b


, the expensive injection molder must be operated by a skilled operator. This increases the cost of the obtained module finger.




Although a demand for a module finger with which the stock of the fingers can be decreased and which can be manufactured to meet the situation has arisen, such a module finger is substantially difficult to become popular.




It is an object of the present invention to solve the problems of the conventionally known module finger and to provide a new module finger with which fingers that need to have various types of shapes can be supplied quickly as required at a low cost.

and

FIGS. 3A

to


3


C, the finger holding member


40


is formed of a plastic main body


41


fabricated with an injection molding. A connecting portion


41


to be connected to the finger member


31


is formed at the upper part (the finger member


31


side) of the finger holding member


40


. A piezoelectric body engaging portion


45


to engage with a piezoelectric body


7


is formed at the lower part of the finger holding member


40


on the opposite side to the connecting portion


41


. The connecting portion


41


has a concave part


42


to accommodate part of the support


34


of the finger member


31


described above. An insertion type concave part


42




a


where the inserting projection


36


of the finger member


31


is to be inserted is formed on the left side of the concave part


42


. The projection


35


of the finger member


31


is to be accommodated in the upper right portion of the concave part


42


. When the inserting projection


36


of the finger member


31


is fitted in the insertion type concave part


42




a


of the finger holding member


40


, the two members


31


and


40


are positioned relative to each other. With the two members


31


and


40


being combined in this manner, the finger holding member


40


has the hole


37




a


at a position corresponding to the hole


37

31


toward the insertion type concave part


42




a


of the finger holding member


40


in a direction indicated by an arrow C in

FIGS. 1 and 3C

. At this time, when the inserting projection


36


of the finger member


31


is inserted in the insertion type concave part


42




a


of the finger holding member


40


, the two members are positioned.




In this manner, when the two members


31


and


40


are combined, the hole


37


of the finger member


31


and the hole


37




a


of the finger holding member


40


are aligned on one straight line. When a pin-shaped member


50


is inserted through the holes

on the module finger


30


side slides along with the swing motion of the piezoelectric body


7


. The piezoelectric body engaging portion


45


is a portion which engages with the tip


16


of the piezoelectric body


7


. These portions are conventionally known structures in the arrangement of the finger, as described in

FIG. 5

, and a detailed description thereof will accordingly be omitted.




The module finger shown in

FIG. 1

,

FIGS. 2A and 2B

, and

FIGS. 3A

to


3


C is merely an example of the module finger of the present invention, and can be modified in various manners. For example, in the module finger


30


shown in

FIG. 1

, the finger member


31


and finger holding member


40


may be integrally combined to each other without using the pin-shaped member


50


but with an adhesive or by ultrasonic welding. In this case, the two members are positioned by inserting the inserting projection


36


of the finger actuating member


31


into the insertion type concave part


42




a


of the finger holding member


40


.




As described above, the concave part


42


and insertion type concave part


42




a


for accommodating at least some lower part (


35


,


36


) of the support


34


of the module finger


30


are formed in one end of the finger holding member


40


. The respective members have the holes


37


and


37




a


so as to form a hole extending through the support


34


and connecting portion


41


when the support is inserted and positioned in these concave parts. As shown in

FIG. 1

, with the finger member


31


and finger holding member


40


being positioned, the pin-shaped member


50


is inserted in the through hole formed by the holes


37


and


37




a


, so that the finger member


31


and finger holding member


40


are integrally connected to each other. With this arrangement, the positional relationship between the butt abutting portion


33


of the finger member


31


and the piezoelectric body engaging portion


45


of the finger holding member


40


(or the positional relationship between the butt abutting portion


33


and the pivot support


43


of the finger holding member


40


) is determined by inserting the supports (


35


,


36


) of the module finger


30


in the concave part


42


and insertion type concave part


42




a


of the finger holding member


40


. Furthermore, when the pin-shaped member


50


is arranged in the holes (


37




a


,


37


) extending through the connecting portion


41


of the finger holding member


40


and the projection


35


of the finger member


31


, the finger member


31


and finger holding member


40


can be positioned more reliably, and the finger member


31


and finger holding member


40


are integrally connected to each other.




Positioning of the finger holding member


40


and finger member


31


by means of the concave parts (


42


,


42




a


) and the supports (


35


,


36


) is not limited to the above embodiment, but can be modified in various manners. In fine, this positioning is achieved by forming at least one portion where part of the finger member and part of the finger holding member are combined to each other face to face, such that the positional relationship between the butt abutting surface of the finger member and the piezoelectric body engaging portion (or pivot support) of the finger holding member relative to each other is defined accurately.




In the manufacture of the above finger module, a plurality of finger members


31


are manufactured and kept in stock for the respective types so as to cope with the knit textures of various types of fabrics. A plurality of types of finger holding members


40


are manufactured and kept in stock in accordance with the specification of the needle selector where the finger module is to be built. Finger members are selected in accordance with the target knit texture, and finger holding members are selected in accordance with the needle selector where they are to be built. The selected finger members and finger holding members are assembled, combined, and integrated as described with reference to

FIG. 1

,

FIGS. 2A and 2B

, and

FIGS. 3A

to

C. As a result, various types of finger modules can be provided.




As the knitting cylinder rotates, the butt abutting surfaces at the tips of the finger members come into intermittent contact with the butts of a large number of needle selection jacks at a high speed. Accordingly, the finger members are preferably made of a metal having high impact resistance and high wear resistance.




The finger holding member engages with one end of the piezoelectric body by its piezoelectric body engaging portion, and receives the swing motion of the piezoelectric body. At this time, since the finger holding member and piezoelectric body engage with each other in continuous contact, the finger holding member requires high shape precision, but does not require high impact resistance or high wear resistance unlike the finger member. Accordingly, a relatively inexpensive resin material, e.g., a plastic material, having high workability is preferably used to form the finger holding member.




As described above, the module finger according to the present invention is formed by fabricating a finger member and finger holding member, which have different performances required in the manufacture and operation, using separate materials, and by combining them. Consequently, various many types of fingers can be formed by combination of a comparatively small number of types of finger members and finger holding members. Since a simple and reliable integral connecting method is employed, a new demand for a high quality finger can be coped with quickly at a relatively low cost.
