Description

Electronically operated jacquard device and cartridge for use in it.

Technical sector

The present invention relates to an apparatus electronically driven jacquard and a cartridge for use in the same.

State of the art

A jacquard device is used to control positions of a plurality of threads placed in a body of machine. More particularly, the apparatus determines a position of a selection pin to manipulate each individual thread or a thread group The selection pin mounted on the body of machine is pushed along its length in a direction to / from the jacquard device.

On the other hand, for the machine body jacquard, an alternative mechanism is provided to perform a alternative movement of this jacquard machine body along of the longitudinal direction of the selection pin. In a state no contact in which the selection pin has no contact with a selection head, the relative position ratio is changed between the jacquard machine body and the selection pin in the longitudinal direction When the jacquard machine body and the selection pin are in their initial positions one respect to another, the selection head may come into contact with the selection pin. In addition, in this contact state, the pin of selection moves against the pushing force in association with a jacquard machine body movement and it is fixed on position.

That is, in the pinless contact state selection in which it is not in contact with the head of selection, the selection pin remains in position initial. In the state with contact, in association with a movement of the jacquard machine body, it only moves with it the selection pin in its condition with contact.

As a result, according to a head position of selection, the position of the pin can be controlled selection.

As a jacquard device of this type, Recently an appliance, a so-called machine, has been used electronically operated jacquard, as disclosed in JP 2001 348 752 A. With this jacquard machine electronically operated, changing the position of the selection head is performed according to a bending movement of a piezoelectric body. With the selection pin selection, using electronic information for thread placement, is possible to obtain a general purpose jacquard machine.

The way driven jacquard machine Electronics uses a so-called cartridge type construction. Plus particularly, in order to operate selectively a fixed number of selection pins (for example, seven pins), the machine includes a plurality of units of cartridges, each unit including a corresponding number (per example, seven) of selection heads to operate the pins Therefore, it is necessary that the machine includes cartridges corresponding in number to a value obtained by dividing the number of selection pins that must be placed between the number of Selection heads included in the cartridges.

Each cartridge includes a fixed number of heads of selection, being able to pivot each selection head so selective between a contact position where you are in contact with the selection pin and a contactless position in which no is in contact with the selection pin, in association with a bending movement of an operating element consisting of a piezoelectric body. The cartridge also includes a pin retention that provides or forms a pivot for the head of selection. In addition, a front end part of this head of selection acts as a contact part to get in touch with the selection pin while an end part of base of the selection head forms an arrangement part of operative element in which the operative element is to be arranged, and beyond this, an electronic control part is provided to control the bending movements of these elements operational

From the base end side of the cartridge, an electronic control section is provided that has a electronic component circuit board to control joining movements of the operational elements, a part of provision of operating element arranged upwards with respect to the same in which a fixed number of operating elements constituted by piezoelectric bodies are arranged to be able to flexing, a head arrangement portion disposed toward above with respect to the same one in which a fixed number are arranged of selection heads, and a pin input part of selection arranged upwards with respect to it (adjacent to front (upper) end of the cartridge) into which the selection pins. In the pin input part of selection, partition walls are provided to divide steps of input of the respective selection pins to each other.

Figure 13 shows details of proximity of a head arrangement part 7b currently preferred by the present inventors for use in the jacquard apparatus with the construction described above.

As shown in Figure 13, in the case of a conventional selection head (8), its front end it is formed as an inclined face (face tilted down to the right in figure 13) and the front end of a selection pin (N) has a hemispherical shape without any special treatment.

In addition, the selection pin (N) is configured to descend along a guiding face (19) of selection pin formed in the cartridge body.

It has been found, however, that the following problem with the use of a conventional construction of This type described above. That is, as shown in Figure 13 (d), as the lower end of the pin (N) selection comes into contact with the inclined face, when the selection pin (N) collides with the selection head (8), to Sometimes the selection pin can bounce as illustrated in (and). A bounce of this type can cause operation wrong.

With regard also to the relationship between selection head (8) and pin guide face (19) of selection described above, these elements come into contact linear with each other, so that a head bounce can occur (8) selection as indicated by an inclined arrow up and to the right in (f). As a result, it is difficult that the selection head (8) adopts a stable position, thus, It tends to fail.

Furthermore, if a pushing force is applied involuntarily to the selection head (8) for some reason in the direction towards the non-contact position side, as illustrated in (g), the constituted operating element (9) by a piezoelectric body it can be subjected to an involuntary pivoting force (indicated by the arrow
left).

Object of the invention

The present invention has been realized in view of the state of the art described above and its object main is to provide a jacquard device operated in a manner Enhanced electronics and a cartridge for use in it, which can guarantee stable selection operations for a period for a long time and that can also guarantee a movement stable selection head although the front end of the selection pin comes into contact with the front end of The selection head.

To achieve the object mentioned above, according to the present invention, a jacquard apparatus is proposed electronically operated comprising:

a cartridge that includes a selection head that can be selected so pivoting between a contact position where it is in contact with a selection pin and a contactless position in which no is in contact with the selection pin in association with a bending motion of an operative element comprising a piezoelectric body and a retention pin that provides a pivot for said selection head;

a body of jacquard machine to permanently support said cartridge; Y

a mechanism alternative to perform an alternative movement of said body of jacquard machine along a longitudinal direction of the selection pin;

characterized in that said selection pin directed towards said selection head has an end of shape convex in volume; Y

one end of said directed selection head towards said selection pin has a concave part to accommodate in said same convex end in volume of the pin of selection.

       \ vskip1.000000 \ baselineskip
    

With the jacquard drive device electronic with the construction described above, when the selection pin is in contact with the selection head, the convex selection head side end in volume of selection pin enters the concave part of the head of selection.

Therefore, the head side end of selection pin selection is fixed in position within the concave part that surrounds or joins the convex shape by volume. For another side, if the previous movement is observed from the head side selection, with the entry of the front end of the pin selection in the concave part, the position relationship between them.

As a result, compared to the case in which the front end of the selection head is constructed simply as an inclined face, the state of retention between They can be stable. Therefore, it is possible to avoid rebound of the selection pin due to a position relationship unstable, an involuntary pivoting displacement of the side of selection head between the contact position and the position without contact as well as the application of an involuntary force to operational element

When implementing the described construction above, according to a further aspect of the present invention, a cartridge is proposed for use in a jacquard powered device electronically, including the cartridge a head of selection that can be pivotally selected from a contact position where you are in contact with a pin selection and a contactless position where you are not in contact with the selection pin in association with a movement of flexion of an operative element constituted by a body piezoelectric and a retaining pin that provides a pivot for said selection head;

including the jacquard apparatus a mechanism alternative to perform an alternative movement of a body of jacquard machine along a longitudinal direction of the selection pin;

said cartridge being fixedly attached to a retention plate of said jacquard machine apparatus;

characterized in that:

said pin of selection directed towards said selection head has one end convex in volume; Y

one end of said selection head directed towards said selection pin It has a concave part to accommodate the same end convex in volume of the selection pin.

       \ vskip1.000000 \ baselineskip
    

Preferably, in the jacquard apparatus electronically operated with the construction described previously, said volume convex shape comprises a shape conical; and said concave part is formed by a pair of sides straight formed at said end of the directed selection head towards the selection pin and extending along the longitudinal direction of the retention pin.

If the concave part is formed by a pair of straight sides (straight faces) formed at said end of the head of selection directed towards the selection pin and that extends along the longitudinal direction of the pin retention as described above, straight sides, as a pair, can come into contact with the conical part of the pin selection.

As a result, the position relationship between they can be even more stable, thus achieving the object of the invention.

Needless to say, the same construction can be implemented in the cartridge according to the described invention previously.

In addition, in the jacquard device powered by electronically described above, preferably, said end of the selection head includes, on one of its faces which is a pivotal front side in the pivoting movement from said contactless position to said contact position, a head side stop part that comes into contact with a cartridge body in said position without contact; Y

a stop part of side is provided concave cartridge to come into contact with said part of head side stop in said contact position, avoiding thus an additional pivoting movement of the selection head.

       \ vskip1.000000 \ baselineskip
    

With the above, as the part of head side arrest and side side detention cartridge enter with their faces in contact with each other, the position of the selection head can be maintained even more stable.

Needless to say, the same construction can be implemented in the cartridge according to the described invention previously.

Still preferably, a length of said selection head from said pivot to a position that is in contact with the selection pin is equal to or shorter than a length from said pivot to an operative position in the that said operating element transmits an operating force to the selection head

With this, the displacement of the element operational can be transmitted reliably to the side end of selection pin of the selection head.

Needless to say, the same construction can be implemented in the cartridge according to the described invention previously.

Detailed description of the invention

An embodiment of an electronically operated J jacquard apparatus according to the present invention that includes a number of machine cartridges electronically operated jacquard of the invention which is used to control the placement of a bar (TB) higher than a lace lace machine (R).

In the following analysis, first, you briefly describe the construction of the lace machine (R) on tiptoe and its operations with reference to figures 1 to 3.

       \ vskip1.000000 \ baselineskip
    

Lace lace machine

Figure 1 shows a schematic construction of the lace lace machine (R), which shows the machine R of lace lace seen from its front side so oblique

With this lace lace machine (R) in operation, a plurality of strands warp threads (w) wrapped around a plurality of folders (Bm) are guided from lower positions of the machine body through a battan (S) to a knitting section to interlock with a plurality of bobbin threads (b) to form a socket (RL) of lace. The lace lace (RL) formed is raised and retained from alternately using a back point bar (BPB) and a front dot bar not illustrated and rises at the same time by a porcupine cylinder (PPR) arranged above and that It has a wire comb around it.

The lace (RL) lace produced is collected then by means of a pick-up roller (W) that is in contact with the porcupine cylinder (PPR).

Now, as shown in Figure 1, with This lace lace machine (R), a mechanism is provided oscillating (not shown) to swing coils (B) that contain the bobbin threads (b), along the direction towards front and back of the lace lace machine (R). The coil position (B) is invariable in relation to the direction to the right / left of the machine (R) lace lace.

Between the batán (S) and the positions of oscillation of the coils (B), bars (BB) are interposed lower and upper bars (TB) arranged in this order mentioned from the lower side of the machine body (the side of batan) to move the warp warp threads (w) along of the direction to the right / left of the machine (R) lace lace. These two types of bars (BB, TB) are configured to place the warp warp threads (w) in position in relation to the direction to the right / towards the left of the machine body. As position relationships between these threads (w) of folding warp and the threads (b) of coil vary in association of time with movements towards front and back of the coils (B), the socket can be formed (RL) on tiptoe.

       \ global \ parskip1.000000 \ baselineskip
    

Next, with reference to Figure 2, will describe this process of lace formation (RL) of lace.

In figure 2, some lines (shown as dotted lines and vertical extension line) shown in parallel to the vertical direction represent the bobbin threads (b). In relationship with these bobbin threads (b), the warp threads (w) of folder are placed using the bottom bars (BB) and the bars (TB) higher.

With this lace lace machine (R), to as the warp warp threads (w) move as along the lateral and forward and backward directions to interlacing with the bobbin threads (b), the socket (RL) of lace. More particularly, each strand warp thread (w) it is specified in its position in a knitted fabric that is going to be formed, having the warp thread (w) of folding parts (ww) transverse alternately that extend along the lateral direction and arched woven advance parts (wh) that they extend along the direction forward and backward, that is, representing the progress of the tissue operation.

In the example shown in Figure 2, from a transverse first part (ww1) which is a first woven part place in the sequence of the tissue operation up to a fourth cross section (ww4) to be knitted later, the thread (w) of warp beater alternatively adopts a position rear face, a front face position, a face position rear and a front face position, relative to the thread (b) coil

In the drawing, the position of each thread (b) of bobbin is shown fixed and the folding warp thread (w) is shows to move between the front side and the back side of this bobbin thread (b). However, with the lace machine (R) of current lace, as explained earlier in the present document with reference to figure 1, in relation to the thread (w) of warp of folder that is in a fixed position in relation with the forward and backward direction of the machine body, the bobbin thread (b) will repeat its position movements at along the direction forward and backward, thus determining the positional relationship between the warp warp thread (w) and the bobbin thread (b).

After the previous description about of the front and back side relationship between the thread (w) of folding warp and bobbin thread (b), then describe the formation of the transverse parts (ww) and the tissue advancing parts (wh) described above.

In this figure 2, stages (a), (b), (c), (d) and (e) show the interlocking positions and states of the thread (w) folding warp on the upper bar (TB) and the bar (BB) lower in the respective states.

As described earlier in the present document, the warp warp thread (w) is placed by means of the upper bar (TB) and the lower bar (BB). Plus particularly, the folding warp thread (w) is inserted into through guide holes (h) provided in the upper bar (TB) and the lower bar (BB), respectively. As shown, the hole (ht) guide provided in the upper bar (TB) is relatively large and has a rectangular shape, thus allowing the folding warp thread (w) adopts a position located on the right side of the bobbin thread (b) or a position located in the left side of it. Meanwhile, the hole (hb) guides provided on the bottom bar (BB) is a relatively guide hole small that can substantially fix the position of the thread (w) of folding warp in it.

Therefore, in Figure 2, step (a), the position of the folding warp thread (w) in relation to the bobbin thread (b) as shown is determined as the Folding warp thread (w) is placed on the left side in the hole (ht) guide provided in the center of the upper bar (TB), thus determining its position in relation to the bobbin thread (b1) which is located on the right end side in the drawing.

Then, as the tissue progresses, the upper bars (TB) move to the left two levels and at the same time the lower bars (BB) move the same amount to the left, in this position, the position of this folding warp thread (w) in relation to the lower thread (b3) which is the third from the right side as well, forming the transverse part (ww1). After this process, the bobbin thread (b) moves along the forward direction and back of the machine body, so that the thread (w) of folding warp is placed on the front side in relation to the bobbin thread (b) to be braided with this bobbin thread (b). This is the state illustrated in Figure 2, step (b). In this way, the described tissue advance part (wh) is formed previously.

In the subsequent weaving process, the movement lateral that involves the upper bars (TB) and the bars (BB) lower (the state shown in figure 2, step (c) to form a transverse part (ww2) and forward and forward movements behind the bobbin thread (b) in the respective stages (change of state shown in figure 2, step (c) to the state shown in the figure 2, step (d), and change of the state shown in figure 2, step (d), to the state shown in figure 2, step (e)), is will be performed repeatedly, so that the tissue of lace lace point.

Figure 3 schematically shows the relationship of position between the upper bars (TB) and the bars (BB) Bottoms on the lace lace machine (R).

       \ newpage
    

These upper bars (TB) and bars (BB) lower are adapted to move respectively along of the right / left direction of the body of machine. For example, the top bar (TB) can adopt one of 33 (thirty-three) positions from 0 to 32 while the bar (BB) Bottom can take one of two positions of 0 and 1. The placement right / left of these respective bars (TB, BB) is performed by machines (Jt, Jb) jacquard provided individually for the respective bars (TB, BB).

That is, the right / left placement of the Upper bar (TB) is performed using a jacquard machine (Jt) upper, comprising a jacquard apparatus (J) according to the present invention. With this machine (Jt) jacquard, the upper bar (TB) is move along the right / left direction in figure 3 in relationship with a spire (D) that is placed vertically with respect to the machine body using a machine (Jt1) jacquard de chapita for the selection of two positions, so that the movement to the left of the bar (TB) above the amount of a placement piece (s) (see figure 4) provided in the front end of the spire.

On the other hand, the lower jacquard machine (Jb) It is built as a machine (Jb) jacquard of selection of two positions, to determine the position of the lower bar (BB) in one of the two positions along the direction towards the right / left of the machine body which is the direction right / left in figure 3.

As shown in Figure 3, the bars (BB) lower are pushed to the left by a mechanism of thrust (springs (sp) of traction) arranged on the opposite side (the left end in figure 3) towards the position of machine layout (Jb) jacquard and front ends (right ends) of the bars are connected to pins (N) of selection through rods (A) of coupling adjustment. The Selection pins (N) are provided in correspondence of one to one with the bottom bars (BB).

       \ vskip1.000000 \ baselineskip
    

Top jacquard machine

Figures 4 to 8 show a construction of placement for the upper bar (TB) used by the machine (Jt) superior jacquard in relation to the present invention.

As shown, the top bar (TB) will be pushes side of machine body (R) lace lace by the spring (sp). So, when you are free of any limitation, the upper bar (TB) is pushed / moved to the side upper left in the drawings. On the other hand, for the bar (TB) upper, a positioning lever (L) is provided for Get hooked with it. And this positioning lever (L) includes a pair of stops (Ba). In the illustrated example, the stop (Ba) located on the left side is a stop (Bab) for a movement towards behind, while the stop (Ba) located on the right side is a stop (Baf) for a forward movement. These movements towards front and back work like a pair. Specifically while the forward motion side mechanism is performing the placement of the upper bar (TB), the side mechanism of backward movement is preparing for an operation of next placement. Therefore, placement operations can be carried out efficiently and continuously, without returning the bar (TB) higher than its original (OP) position (its movement towards the lace body machine (R) by the mechanism of push).

Now, for the stops (Ba), a couple of drive blades (DB) that perform an alternative movement between the original illustrated position (OP) and a position (PD) of placement. Also, with respect to these drive sheets (DB), the drive sheet (DB) located on the left side in the Figure is the leaf (DBb) of backward motion drive and the drive sheet (DB) located on the right side in the Figure is the leaf (DBf) of motion drive towards in front of. The drive sheets (DB) are constructed so that when the upper bar (TB) is in a movement towards Forward or backward, a corresponding drive DB sheet only to it performs an alternative movement along the right / left direction in the figure.

In the above, the bar (TB) has been described upper and the lever (L) operatively connected to it. As shown in Figure 4 etc., on the bottom side of the lever (L), the vertical positions of the parts (s) of placement are controlled according to the forward movement and the backward movement, respectively.

The control of this vertical position is carried out by means of a spindle (D) provided for each piece (s) of placement, a selection pin (N) provided down with respect to the spout (D) and a jacquard cartridge (C) driven from electronic way (cartridge) also related to this invention and intended to control the above components.

The chapita (D) includes, in its end part top, the placement parts (s) described above for its use in the placement of the lever (L). The spider (D) includes also, in its intermediate part, large diameter parts Da for limit the fall motion to lower end positions of the same, in joint action with a limitation plate (P1) shown in figure 4.

When the selection pin (N) is raised, the lower end of the spire (D) also rises as Contact this selection pin (N).

The selection pin (N) is an element to bar mode, which includes, at its front end, a part (Na) that is in contact with the spire that can be activated to enter in contact with the lower end of the spout (D) to raise it. As shown, this part (Na) that is in contact with the spire is formed as an enlarged diameter part, whose downward movement is limited by the plate (P2) of limitation.

Each cartridge (C) jacquard drive electronic is configured to contact the pin (N) selection from its lower side in association with a operation of a selection head (8), thus guiding pin N of selection and also the spine (D) to its elevated positions.

Next, with reference to figures 4, 5, 6, 7 and 8, the operation of the upper bar (TB), lever (L), spindles (D), pins (N) selection and selection heads (8) included in the cartridges (C) jacquard electronically operated.

Figure 4 shows a state characterized because both cartridges (C) are in their descended positions (the lower level) and the lever (L) connected to the bar (TB) upper is in its rightmost position (the position (OP) original lever (L)). This original position (OP) is set by an action of a return mechanism (no shown) included in the lace lace machine (R). In this position (OP), the placement parts (s) can move towards above between the drive sheet (DB) and the stop (Ba).

Figure 5 shows a placement status of the upper bar (TB) at the time of forward movement. In this, between the drive sheet (DBf) and the stop (Baf) corresponding to the forward movement, a plurality of placement pieces (s) move up and are fixed on position. At this time, the jacquard cartridge (Cf) of electronic drive for forward movement (level more superior).

Figure 6 shows a state that is performed with a time interval from the state of figure 5. In this status, the drive jacquard cartridge (Cf) is lowered Electronic forward movement. In this state, between the drive sheet (DBf) and stop (Baf) corresponding to the forward movement, the plurality of placement pieces (s) they bind and retain, so that the spire (D) maintains its position. In this, the position relationship between the lever (L) and the cartridges (Cf, Cb) is a relationship in which the cartridge side is shifted to the right side, relative to the state shown in figure 4. As for the jacquard machine, in fact, put that the cartridge side position is fixed, the lever (L) (for therefore, the upper bar (TB) is located on the left side in the Figure 4. Figures 7 and 8 also show position relationships relative to different cartridge side positions relative to the lever (L).

Figure 7 shows a placement status of the upper bar (TB) during an initial phase of movement towards behind. With the time interval from the state shown in the Figure 6, while the jacquard machine (Cf) operated in a manner electronic forward movement remains lowered, the machine (Cb) jacquard electronically driven movement backwards rises. In this state, enter the sheet (DBb) of drive and stop (Bab) corresponding to the movement towards back, the plurality of placement pieces (s) rise according to the selection head position (8) included in this cartridge (Cb).

Figure 8 shows a placement status of the upper bar (TB) in the backward movement, after the state shown in figure 7. With the time interval, the Cartridge (Cf) jacquard electronic motion drive forward is retained in its downward position while the cartridge (Cb) jacquard motion electronic drive backwards rises. In addition, between the drive sheet (DBb) and the stop (Bab) corresponding to the backward movement, the plurality of placement pieces (s) are joined and retained, thus completing the placement of the upper bar (TB) in the backward movement.

Figure 9 shows the detailed construction of the described electronic drive jacquard cartridge (C) previously. On top of this cartridge (C), it define a plurality of holes (5) of selection pin in those who will be guided and inserted the plurality of pins (N) of selection.

Figure 11 shows a selection pin (N) in detail. As shown, the selection pin (N) includes, at its lower end, a conical part (N3) that enters head contact (8) selection. Therefore, as is shown in figure (12) in positions (d) and (g), in the state of contact between a concave part (14) of contact formed in the selection head (8) and this selection pin (N), this state Contact can be performed reliably and stably, avoiding for example the bounce offset of the pin (N) of selection. More particularly, this state of contact between they are made as a linear contact as indicated by a line point and line in figure 11.

Now, for the jacquard machine body (1), as shown in figure 3, a mechanism (6) is provided alternative to perform an alternative movement of the body (1) of jacquard machine, therefore, the jacquard cartridge (C) of electronic drive along the vertical direction of so that the spout (D) and the placement parts (s) can move up along the vertical direction.

The head part (8a) is formed with a length equal to or shorter than the input part (8b) of operational element More particularly, as observed in from the pivot (PIV) formed by the retaining pin (12), regarding the relationship between the operational position of the element (9) operational (arm length is indicated by (p1)) and position operation of the concave part (14) of contact formed at the end front of the head part (arm length is indicated by (p2)), the operating position of the concave contact part (14) is it is closest to the pivot (PIV) (that is, p1? p2). How result, a small displacement of the element can be transmitted (9) operating at the head stably.

As shown in Figure 10, the part (8a) head includes the concave part (14) of contact that is extends down. As can be understood from the Figure 11, this concave part (14) of contact is constituted by a combination of two straight sides (15, 16) (flat sides) straight) that extend along the thickness direction of the head part (8a) (which is the longitudinal direction of the pin (12) retention, the direction of depth in figure 10). As a result, as shown in Figure 12 (d), the part (N3) conical provided on the front end of the pin (N) of selection can fit tightly or tightly in this part (14) concave contact. Therefore, as described earlier in this document, the state of contact between these two parts are performed as a linear contact, as is represented by the dotted and dashed line in figure 11.

With the construction described above, in the front end of the head part (8a), the part (15) of straight side located on the left side in figure 12 works as an inclined guiding part to guide the head (8) of selection from the contactless position to the position of contact when the selection pin (N) is placed in contact with the head (8) of selection. In the example shown in the figure 12, this part is formed as an inclined face that extends up to the left from its base end (the side lower in the figure) to its front end (upper side in the figure). In operation, since the front end of the selection pin (N) comes into contact with this inclined face, the selection head (8) will swing to the left which is the contact position side, thus making the position of contact be stable.

Also, at the front end of the head (8) selection and on the left side in figure 2, that is, in its face which is the front side pivotally in the pivoting movement of the selection head (8) from the position no contact to the contact position, a part is provided (17) head side arrest that comes into contact with the body (7) of the cartridge in the contact position.

On the other hand, in the cartridge body (7), it provides a cartridge side stop (18) to enter contact with a left end face of the part (8a) of head when the selection head (8) is adopting the position of contact, thereby avoiding additional pivoting movement of this selection head (8). Specifically, as is shown in figure 12, this part (18) of side stop cartridge is intended as a concave part that is concave from the guiding face (19) of body selection pin (7) of cartridge in its direction to the right / to the left (side pivoting front), so that the head part (8a) and the part (18) cartridge side stop contact face each.

The operative element input part (8b) It is intended as an extension part that extends on the side rear of the selection head (8), and in a central part in as for the thickness thereof, an entry hole (20) is provided into which the operative element (9) enters. This hole (20) of entrance is planned as a game hole that allows movement pivoting of the element (9) operative therein.

Operating element arrangement part

Within the provision part (7c) of operating element, a number of elements are arranged (9) operations constituted by corresponding piezoelectric bodies to the number of the selection heads (8). Each one of these operational elements (9) have their fixed rear end for provide a pivot and has its front end that enters the entrance hole (20) of the selection head (8). The operating elements (9) receive control signals respectively for them from the component circuit board (10) electronic section (7d) of electronic control, so that each operative element (9) flexes in its direction towards the right / left in figure 12. This body piezoelectric is specifically a ceramic transducer piezoelectric. As a result, its bending motion controls the pivoting movement of the selection head (8).

Electronic control section

Within this control section (7d) electronic, component circuit board (10) is provided electronic devices to control the operation of the elements (9) operational According to control information transmitted separately to the electronically driven jacquard cartridge (C), it perform the control functions (switch control of selection) to control the pivoting movements of the elements (9) operational.

Referring to the materials they form the respective parts of the jacquard cartridge (C) driven in a manner electronics, cartridge body (7), retaining pin (12) and the selection head (8) are formed respectively of Resin and the selection pin (N) is formed of metal.

In the foregoing, the machine constructions (Jt) jacquard operated in a manner electronic and jacquard cartridge (C) driven in a manner electronics according to the invention. Next, your operation with reference to figure 12.

This figure illustrates a series of movements, showing pivoting movements of the selection head (8) in operational association with pivoting movements of the element (9) operating that is located on the bottom side. In association with the reciprocating vertical movement of the cartridge (C), the pin (N) of selection moves vertically with respect to the cartridge (C). In this figure, the down arrow of the selection pin (N) represents an upward movement of the cartridge (C).

In the position of Figure 12, (a) shows a state in which the selection pin (N) and the cartridge (C) are in their initial positions, in which the selection pin (N) is retained in the contactless position which is its initial position while the cartridge (C) (also the machine body (1) jacquard) is located in its lowest position (the position lower).

Next, the operation will be explained from the left side in the figure.

1. Initial position

This is a status of the position relationship shown in position (a), characterized in that the head (8) of Selection adopts the contactless position.

2. The selection pin enters while the head of selection adopts contactless position

From the state shown in position (a), the additional condition shown in position (b) is performed when the selection pin (N) additionally enters the cartridge (C) while the selection head (8) maintains its position.

In this, as shown, since the cartridge (C) moves up, the selection pin (N) enters the cartridge (C) to a more internal position in the same.

3. Selection head contact position

In the state shown in position (c), with receipt of operational contact position information for the selection pin as knitting data, the element (9) operating is swung to the right side to pivot the Selection head (8) to its contact position. In this state, when the cartridge (C) moves up, this causes a relative downward movement of the selection pin (N), so that the conical part (N3) of the selection pin (N) enters contact with the upper end of the selection head (8). How result, the selection pin (N) and eventually the spigot (D) moves up and the placement piece (s) is retained in its elevated position, so that the position of the bar (TB) upper can be fixed stably.

In the operating mode described above, even when the selection pin (N) bounces when it comes into contact with the selection head (8) as shown in position (e) or the selection head (8) per se bounces from its contact position to the non-contact position as shown in position (f), due to the ingenious arrangements described above in the form of the leading end of the selection head (8) and the shape of the lower end of the Selection pin (N), the good and stable operating conditions shown in positions (d) and (g) can be realized.
