Definitions

  • the present invention relates to an electronic driven jacquard apparatus and a cassette for use therein.
  • a jacquard apparatus is used for controlling positions of a plurality of threads set on a machine body. More particularly, the apparatus determines a position of a select pin for handling each single thread or a group of threads.
  • the select pin mounted on the machine body is urged along the length thereof in a direction to/away from the jacquard apparatus.
  • a reciprocating mechanism for reciprocating this jacquard machine body along the longitudinal direction of the select pin.
  • the select pin Under a non-contacting condition where the select pin is free from contact with a select head, the relative positional relationship between the jacquard machine body and the select pin in the longitudinal direction is changed.
  • the select head can contact the select pin.
  • the select pin is moved against the urging force in association with a movement of the jacquard machine body and fixed in position.
  • the select pin under the non-contacting condition of the select pin not contacting the select head, the select pin is maintained at its home position. Under the contacting condition, in association with a movement of the jacquard machine body, only the select pin under its contacting condition is moved therewith.
  • the position of the select pin can be controlled.
  • the electronic driven jacquard machine employs a so-called cassette type construction. More particularly, in order to selectively operate a fixed number of select pins (e.g. seven pins), the machine includes a plurality of units of cassettes, each unit including a corresponding number (e.g. seven) of select heads for operating the pins. Therefore, the machine needs to include cassettes corresponding in number to a value obtained by dividing the number of select pins to be positioned with the number of select head included in the cassettes.
  • Each cassette includes a fixed number of select heads, each select head being selectively pivotable between a contacting posture contacting the select pin and a non-contacting posture not contacting the select pin, in association with a bending movement of an operational member comprised of a piezoelectric body.
  • the cassette further includes a retaining pin which provides or forms a pivot for the select head. And, a leading end portion of this select head acts as a contacting portion to come into contact with the select pin, whereas a base end portion of the select head forms an operational member disposing portion where the operational member is to be disposed, and further beyond this, there is provided an electronic controlling portion for controlling bending movements of these operational members.
  • an electronic controlling section having an electronic component circuit board for controlling binding movements of the operational members, an operational member disposing portion disposed upwardly thereof where a fixed number of operational members comprised of piezoelectric bodies are disposed to be bendable, a head disposing portion disposed upwardly thereof where a fixed number of select heads are disposed, and a select pin entering portions disposed upwardly thereof (adjacent the leading (top) end of the cassette) which the select pins enter.
  • the select pin entering portion there are provided partitioning walls for partitioning entrance passages of the respective select pins from each other.
  • Fig. 13 shows details of vicinity of a head disposing portion 7b presently preferred by the present inventors for use in the jacquard apparatus having the above-described construction.
  • a select head 8 As shown in Fig. 13 , in the case of a conventional select head 8, its leading end is formed as an inclined face (face downwardly inclined to the right in Fig. 13 ) and the leading end of a select pin N has a semi-spherical shape without any special treatment.
  • select pin N is configured so as to be lowered along a select pin guiding face 19 formed in the cassette body.
  • the operational member 9 comprised of a piezoelectric body may be subjected to an inadvertent pivotal force (indicated by the left arrow).
  • the present invention has been made in view of the above-described state of the art and its primary object is to provide an improved electronic driven jacquard apparatus and a cassette for use therein, which can ensure stable selecting operations for an extended period of time and which can ensure also stable movement of the select head even the leading end of the select pin comes into contact with the leading end of the select head.
  • an electronic driven jacquard apparatus comprising:
  • the select head side end of the select pin is fixed in position within the concave portion which surrounds or binds the cubically convex shape.
  • the positional relationship therebetween is fixedly determined.
  • the retention condition therebetween can be stable. Consequently, it is possible to prevent the rebounding of the select pin due to unstable positional relationship, an inadvertent pivotal displacement of the select head side between the contacting posture and the non-contacting posture as well as application of an inadvertent force to the operational member.
  • a cassette for use in an electronic driven jacquard apparatus including a select head pivotally selectable between a contacting posture contacting a select pin and a non-contacting posture not contacting the select pin in association with a bending movement of an operational member comprised of a piezoelectric body and a retaining pin providing a pivot for said select head;
  • the jacquard apparatus including a reciprocating mechanism for reciprocating a jacquard machine body along a longitudinal direction of the select pin; said cassette being used fixedly attached to a retaining plate of said a jacquard machine apparatus; characterized in that:
  • said cubically convex shape comprises a conical shape; and said concave portion is formed of a pair of straight sides formed at said end of the select head facing the select pin and extending along the longitudinal direction of the retaining pin.
  • the concave portion is formed of a pair of straight sides (straight faces) formed at said end of the select head facing the select pin and extending along the longitudinal direction of the retaining pin as described above, the straight sides, as a pair, can come into contact with the conical portion of the select pin.
  • said end of the select head includes, in a face thereof which is a pivotal front side in the pivotal movement from said non-contacting posture to said contacting posture, a head side stopper portion which comes into contact with a body of the cassette under said non-contacting posture; and there is provided a concave cassette side stopper portion for coming into contact with said head side stopper portion under said contacting posture, thus preventing further pivotal movement of the select head.
  • the posture of the select head can be maintained in an even more stable manner.
  • a length of said select head from said pivot to a position contacting the select pin is equal to or shorter than a length from said pivot to an operational position where said operational member transmits an operational force to the select head.
