Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jacquard machine having a pair of counter-moveable knives passing each other and a stiffness controllable by a cross needle (main needle), in particular a double-acting full-opening jacquard machine. In this case, the rigid blade is not configured in a bipedal shape, and the rigid blade is provided with two main hooks which are received and engaged with the driving members provided on the pair of knives, and the main hooks are received and engaged with the driving members provided on the pair of knives. This invention relates to a type in which a free range is provided for making it possible to control the movement and adjustment of firmness by means of a cross needle to a position where alignment cannot be achieved.

The known conventional double-acting, full-opening jacquard machine has a double-leg structure with a horizontal needle that is controlled to push and move, and each leg is provided with a main hook, and one leg is equipped with a lock. It looks like it has a hook.

The main hook belongs to a pair of knives that pass each other and are movable up and down oppositely, and these movable knives serve to lift the stiffener from the lower rod opening position to the upper rod opening position, while the locking hook belongs to a stationary locking knife that is different from a moving knife.

The locking knife serves to ensure that the lock remains in place in the raised upper lever position.

The disadvantage of this type is that when a pair of counter-moving knives pass each other, care must be taken to ensure that the rigidity, which is moved downward from the upper to the lower lever position, is not grasped by the rising knife. However, in order to ensure that this condition is met, the control of the pushing motion of the vertical nail by the horizontal needle must be maintained until the time when the pair of knives pass each other, and therefore, in order to maintain this, This creates an unfavorable state of motion in the reading mechanism, which requires approximately half a shed stroke, corresponding to approximately 180 degrees of crankshaft rotation, to move the transverse needle along with the card, and its maintenance over such a long period of time. This causes a large amount of friction at the point of contact between the horizontal needle and the vertical nail, which has a disadvantageous effect on the movement of the vertical nail and the horizontal needle that presses it.

In order to overcome this drawback, there are some types in which a pair of counter-moving knives are shifted vertically so that they do not pass each other, but this requires an extra length of illumination. This is by no means an advantageous solution, since it has the effect of increasing the instability of its motion and increases the overall height of the machine accordingly.

Therefore, an even more advantageous solution was proposed in Japanese Patent Application Laid-open No. 52-214.
It is known from the specification of No. 62 (Japanese Patent Application No. 51-88976).

According to this, a pair of knives that are movable in opposite directions and pass each other are arranged parallel to a horizontal needle (main needle),
The illuminator is not configured in a bipedal shape, but is provided with two main hooks belonging to the pair of knives, and is placed between the pair of knives.

The pair of knives are provided with driving members spaced apart from each other in the longitudinal direction (lengthwise direction) of the knives in order to receive the main hooks of the lights, and the lights are free between the driving members. It is said to be adjustable within a range.

This is because the push adjustment control movement by the horizontal needle of the illumination is
It is carried out along the longitudinal axis of the knife (longitudinal axis), as opposed to previously known conventional jacquard machines, which are carried out at right angles to the knife longitudinal axis (longitudinal axis). It is required that the

The entraining member of the knife is configured such that the entraining surface can entrain the main hook belonging to the instrument when the instrument changes its shed position together with the main hook of the instrument; The main hook resting on top slides on this entrainment surface, so that the light contacts the knife, while the free main hook is freed from the range of movement of another knife which is movable oppositely. It is assumed that

On the other hand, if the main hook of the light is located in the free range between the carrying parts of the knife, the light remains in its basic position.

However, in this type of known solution, the knife is arranged parallel to the cross needle, and the push adjustment control movement of the illuminated cross needle is carried out along the longitudinal axis of the knife. This is a requirement, and in this respect the structure is fundamentally different from the previously known conventional Jacquard machine, in which the knife was arranged at right angles to the horizontal needle.
Not only does this result in structural complexity and inconveniences in machine installation and handling, but
The biggest drawback is that the pitch of the horizontal needle or the pitch of the illumination, which corresponds to the perforation pitch in the row direction of the card to perform the reading movement of the horizontal needle, is determined by the arrangement interval of the knives, so the perforation pitch dimension of the card is In order to make the width dimension of the card in the perforation row direction, which is defined by this, smaller than that of the previously known conventional Jacquard machine, it became necessary to form the knife from a fairly thin plate bar material. Because it is long and cannot form any support at the middle part other than both ends, it does not have sufficient strength, and it is easy to bend, causing problems in reliable movement and high-speed operation. It is a possibility.

The object of the present invention is to eliminate the above-mentioned drawbacks of the knife of the type known from the specification of JP-A-52-21462, to make the knife thicker and to sufficiently increase its strength. Moreover, the pitch of the horizontal needles and illuminators corresponding to the perforation pitch in the card row direction can be made considerably smaller, thereby ensuring reliable movement and high-speed operation, and further increasing the efficiency of the machine. It is.

According to the present invention, the knife driving member for receiving and engaging the main hook of the illuminator is not provided directly on the knife, but is provided on a plate-like member attached to the knife. The plate has a surface perpendicular to the knife and is a tongue-like body projecting obliquely upward to the side of the plane of the entraining member, the free range being between the knife and the entraining member. This is achieved by arranging the knife in a direction transverse (perpendicular) to the transverse needle.

In short, the light is pushed and adjusted by the main needle in a direction perpendicular to the length direction of the knife on the surface of the plate-like member in that direction. If it is placed in the free range formed in the plane of the plate-shaped element between it and the driving element, the illumination remains in its basic position without the main hook being received in the driving element.

Therefore, the direction in which the knife crosses the horizontal needle (perpendicular direction)
Since the knives are arranged at a very large pitch, the spacing between the knives can be set fairly large without being affected by the pitch of the horizontal needles and illuminators, which corresponds to the perforation pitch in the row direction of the leading edge. It can be made thick and durable.

Moreover, the entraining member for receiving and engaging the main hook of the illumination is an individual plate-shaped member of a size that is not so large but is attached to the knife in parallel with the horizontal needle, intersecting (orthogonal to) the knife. Since each plate-like member can be made quite thin without much problem in terms of strength, it can be attached at a fairly small pitch, and this allows the pitch of horizontal needles and vertical nails corresponding to the perforation pitch in the row direction of the card to be made quite small. It can be done.

Furthermore, the fact that the entraining member is not provided directly on the knife but on the plate member reduces damage to the knife;
This contributes to making it easier to adjust the attachment pitch or arrangement pitch of the vertical nails and horizontal needles as well as the plate-like members, and to facilitate their individual inspection, repair, and replacement.

In the present invention, individual upright plate-like members are attached to project from the space between oppositely adjacent pairs of knives on both sides of each knife in a direction intersecting (perpendicular to) the knives.

Therefore, between adjacent pairs of knives, the portions of the plate-like members extending from the respective knives extend in opposite directions and are opposed to each other.

Advantageously, the projecting portions of the plate-shaped member on both sides of the knife are present at the same location on both sides of the knife and are formed as a single piece, but if necessary they can be present with slight offsets in the length direction of the knife.

One each near or at the tip of the protruding portion on both sides of the knife of each plate member or 2Ili! ill entraining members are provided on the sides of the plate-like member and protrude oppositely from each other.

At least one of the parts of the individual plate-like elements that project on both sides of the knife is provided with a suitable projecting distance between the knife and the driving member, which distance forms a free range.

Each plate member is arranged and attached to each knife at exactly the same pitch in the length direction of the knife.

Each plate-like member may be located at the same location on each knife with matching pitches, or each pair of adjacent knives may have a slight overhanging portion facing each other in opposite directions between the knives. or in a staggered pattern with a deviation of half the pitch of the attached pitch, and in the former case, the parts of each adjacent pair of knives that protrude in opposite directions from each other come into contact with each other. It is necessary to set the length so that the distance does not overlap.

In any case, a vertical nail is made to exist between a pair of adjacent knives, between adjacent portions of the plate-like members from those knives that protrude in opposite directions, and the plate-like members Adjacent parts of the protruding parts between the two knives are provided so as to protrude oppositely from the sides of the vertical nail correspondingly to the respective driving members that protrude so as to face each other. The two main hooks are brought into appropriate receiving engagement to carry out the entrainment when changing the shed position of the vertical nail, while the horizontal needle pushes the vertical nail in a direction transverse (orthogonal) to the length of the knife. 2 when the main hook of the vertical peg is moved along the plate into a free range due to the overhanging distance between its knife and the driving member.
None of the two main hooks are in receiving engagement with the entraining member and are not entrained.

Here, the distance between the tips of the two main hooks that protrude in opposite directions from the sides of the vertical nail is the distance between the adjacent parts of the parts of the plate member that protrude in opposite directions between the knives. It is smaller than the spacing between adjacent mutually projecting entrainment members of the projecting portions.

As in the case where each plate-like member is made to exist at the same location by matching the attachment pitch on each knife, it is necessary to provide a gap between the opposing overhanging portions of a pair of knives so that they do not come into contact with each other, and therefore, the If the opposing protruding driving members of the protruding parts require an interval that is offset from each other in the direction that intersects the knife, the two main hooks of the vertical nail must also be spaced apart from each other to the left and right in accordance with this. It is provided so as to protrude from opposite sides of the vertical nail.

On the other hand, when the plate-like members are arranged in a staggered manner by shifting the attachment pitch for each knife, the opposing projecting parts between a pair of knives are inserted into each other. In the case where the two protruding parts of the protruding portions are arranged so that they overlap each other, and the driving members of the protruding parts are located at the same place between the pair of knives, the two parts of the vertical nail The main hook is provided so as to protrude symmetrically from both sides of the vertical nail at the same location without requiring the above-mentioned offset.

The driving member that projects contrary to the side of the plate-shaped member and the main hook that projects contrary to the side of the vertical nail corresponding to this,
It is advantageous that both of them are provided at the same height level with respect to the plate-like member and with respect to the vertical nail, but in some cases, they may be provided with different height levels above and below.

The entraining member has a slope for receiving and engaging the main hook, and can be formed as a plate hook-shaped tongue projecting diagonally upward from the side of the plate member. It can be formed by bending or punching a part of it.

The main hook can be formed as a plate hook-like tongue or bar that projects obliquely downward from the side of the vertical nail, and can be easily formed by bending a part of the vertical nail.

The vertical nail is preferably formed as a flat bar, but is not limited thereto and may also be in the form of a round bar.

According to one embodiment of the present invention, a space such as a recess or a hole capable of receiving the main hook is provided above the driving member of the plate member, and a space such as a recess is also provided below the main hook of the vertical nail. established,
The main hook placed on the mounting surface of the driving member slides on the mounting surface due to the load applied to the vertical nail, and the receiver is inserted in the space between the main hook and the driving member, and the vertical nail is drawn into contact with the plate, whereby the free main hook of the other vertical peg is released from the range of movement of the entraining member of the plate of the other counter-moving knife and is no longer in receiving engagement.

According to another more advantageous embodiment of the present invention, the two main hooks projecting laterally and oppositely to each other are tiltable integrally with respect to each other about a pivot in a direction that intersects the direction of their protrusion. It is assumed that it is pivoted to the nail.

In this case, when one of the main hooks is received and engaged with one of the driving members, the load applied to the vertical nail causes the main hook to tilt upward about the pivot axis, and at the same time, the other The free main hook is tilted downwards so that it rests against the side surface of the peg, so that the other free main hook can move into the driving member of the other peg without the peg touching the plate. Release from the range of motion and no receptive engagement is achieved.

In this case, as in the previous embodiment, no space is required above the plate-like member's guide member or below the main hook of the vertical nail, and the vertical nail does not come into contact with the plate-like member, so reliable operation can be expected. , which is advantageous for high-speed operation.

In this case, the two main hooks are balanced around the pivot axis with respect to the vertical nail, and are automatically restored from the tilted state. A restoring biasing spring is provided so that the restoring is performed.

Note that the locking knife can be arranged parallel to the moving knife and intersecting (orthogonal to) the horizontal needle, or conversely, it can be arranged so that it is intersecting (orthogonal) to the moving knife and parallel to the horizontal needle. The locking hook of the peg belonging to the locking knife is provided on the side of the peg with a corresponding orientation.

When the locking knife is placed parallel to the horizontal needle, a slope for mounting the locking hook is formed by bending or punching a part of the knife so that it protrudes to the side of the locking knife and forms a diagonally upward hook. A locking member consisting of a tongue-shaped body with a hole is provided above the locking knife, and a space such as a recess is provided on the upper side of the locking member. Provided as a hook-shaped item that protrudes from the side of the vertical nail,
As a result, when the locking hook is placed on the mounting surface of the locking member, the locking hook slides on the mounting surface due to the load applied to the vertical nail, and the locking hook and locking knife are separated. It can be fitted into the space and the vertical nail touches the locking knife.

The present invention will be described below with reference to illustrated embodiments.

The first embodiment shown in FIGS. 1 to 3, which corresponds to a double-acting, full-opening jacquard machine, shows a pair of knives 1, 1 which are vertically movable oppositely and pass each other. 1
, 1 serve to lift the vertical nail 2.

The knives 1, 1 are attached with plate-like members 3, 3 that stand upright perpendicular to the length direction of the knives 1, 1.

The vertical nail 2 is carried by the knives 1, 1 by the main hook 4 on its upper part being engaged with a carrying member 5 provided on the plate member 3.

A cross needle (main needle) 6, which is essential to a reading device (not shown) for controlling the vertical nail 2, is inserted in a direction perpendicular to the length direction of the knife 1°1 and parallel to the plate member 3. It is extending.

In FIG. 1, an arrow indicates the longitudinal direction of the machine, and the horizontal needle 6 extends in the direction of this arrow.

A stationary locking knife 7 is arranged parallel to the direction in which the horizontal needle 6 extends in the direction of this arrow, and this locking knife 7 locks the vertical nail 2 in the raised position with the locking member 8. The receiving engagement of the locking hook 9 serves to retain the vertical nail 2 in its raised upper lever position.

The plate-like members 3 are attached at a predetermined pitch in the length direction of the knife 1, and when viewed from above, the pitches are matched for each knife 1 and the plate members 3 are located at the same location (see FIG. 3).

As shown in FIG. 4, the plate-like member 3 is a single piece having portions on both left and right sides of the knife 1 that protrude in a direction perpendicular to the length direction of the knife, and a surface perpendicular to the length direction of the knife. It has two entrainment members 55 that protrude symmetrically and oppositely to the sides of the surface of the plate-like member at the same height level near the tips of the parts that protrude on both sides, and both protrude. The tips of the parts are upright edges 10, 10, and one of the protruding parts is provided with an appropriate protruding interval between the knife 1 and the driving member 5, and the surface of the plate-like member in this interval is free. A range 11 is formed.

The plate-like member 3 has a portion between the pair of knives 1, 1 that protrudes in opposite directions, and between the tips of each portion, the portions that are aligned in plan view do not come into contact with each other. The length is such that a slight gap is formed.

As a result, the illumination 2 is made to exist at the interval of the attachment pitch of the plate-like member 3 between the pair of knives 1, 1,
The knives 1 are attached to each of the pair of knives 1, 1, and the parts of the two plate members 3, 3 which are diagonally adjacent when viewed from above, protrude from each other in opposite directions between the pair of knives. Two driving members 5, 5 which protrude in opposition to each other with an offset in the cross direction serve to lift and carry the illuminator 2.

The entraining member 5 is a tongue-shaped body that is partially bent from the plate-like member 3 and protrudes diagonally upward at an appropriate angle. It is a slope, and there is a concave space above the entraining member 5 of the plate member 3.

As shown in FIG. 5, the illumination 2 is made of a flat rod, and has a T-shaped upper end, and the above-mentioned two driving members 5 are attached at both left and right ends of the T-shape.
, 5, two main hooks 4, 4 protrude oppositely from the sides of the light fixture 2 at the same height level with a deviation corresponding to the deviation between the two main hooks 4, 4.
have.

The main hook 4 is made of a tongue-like body formed by bending a part of the illumination 2 to protrude obliquely downward in correspondence with the driving member 5, and there is a space below the main hook 4.

The interval between the protruding tips of the two main hooks 4, 4 of the light is smaller than the inner interval of the attaching pitch of the plate-like member 3, and the two protruding ends facing each other with a staggered position are used to carry the light. This is larger than the distance between the protruding tips of the entraining members 5,5.

Accordingly, as shown in FIGS. 6 and 7, one of the main hooks 4 of the illumination 2 is placed on and engaged with the driving member 5 of the plate-like member 3 of one of the knives 1 belonging thereto. When the main hook 4 slides downward on the mounting surface due to the tensile load applied to the light fixture 2, the main hook 4 and the driving member 5 are connected to the upper side of the driving member and the lower side of the main hook. Fitting into the space, the illuminator 2 comes into contact with one of the plate-like members 3 as if being drawn to it.

This allows the other free main hook 4 on the opposite side of the illumination 2 to
is retracted and released from the movement range of the driving member 5 of the plate-shaped member 3 of the other counter-moving knife 1 belonging thereto to a position where it does not come into contact with it.

Therefore, the illumination 2 is in a downward movement tendency, the knife 1,
1 pass each other, the other free main hook 4 can be attached to the rising knife 1 without the need for a suppression adjustment control by the cross needle 6 even to this point.
without being carried away by the movements of

In this case, when the illumination 2 comes into contact with the plate-like member 3, if there is a risk that it will come into contact with another plate-like member that faces and aligns with that plate-like member, causing a problem, the upper end of the illumination 2 should be The two main hook portions may be provided with a slight lateral step-like deviation, or the plate-like member 3 may be attached to each pair of knives 1, 1 with a slight deviation without being completely aligned. .

The pressure adjustment control movement of the light fixture 2 is controlled by the horizontal needle 6, which moves the knife 1,
This is carried out in a direction along the plate member 3 perpendicular to the length direction of the plate member 1 .

As a result of this movement, as shown in FIGS. 8 and 9, when one of the main hooks of the light fixture 2 is moved to the free range 11 of the plate member 3 and positioned opposite thereto, the main hook Each hook 44 has its own entraining member 5.5.
The illuminator 2 is not lifted up by the vertical movement of the knives 1, 1, and is not retracted from the receiving engagement.
Stay in that basic position.

This operation is performed by slight tilting without requiring any bending or deflection of the illuminator 2.

The locking knife 7 has a locking member 8 consisting of a tongue-shaped body that is partially punched out and bent laterally and projects diagonally upward.
The upper side of the member 8 has a space for a punched hole.

Correspondingly, the locking hook 9 is also made of a tongue-shaped body that is formed by punching and bending a part of the light fixture 2 laterally and protruding diagonally downward. A hole space is formed.

As a result, the locking hook 9 is placed on the locking member 8,
The vertical nail 2 slides downward due to the tensile load applied to the vertical nail 2 on its mounting surface, and the locking hook 9 and the locking member 8 fit into the rain space, and the vertical nail 2 contacts the locking knife 7. As a result, the vertical nail 2 remains at the lifted upper lever position.

The disengagement of the locking hook 9 from the locking member 8, which is necessary for lowering the vertical nail 2 to the lower punching position, is performed by the main hook 4 being carried by the knife 1, which is raised to the upper punching position of the vertical nail 2. This is carried out by a slight lifting by the receptive engagement of the cross needle 5 and the previously described pushing adjustment control movement of the cross needle 6.

However, in this lever configuration, since the knives 1, 1 are arranged in a direction perpendicular to the horizontal needle 6, the arrangement pitch of the knives is not related to the perforation pitch in the row direction of the card. Because they are not directly related, the pitch of the knife array can be made considerably larger, making the knives thick and strong without the risk of bending, etc., allowing reliable movement and high-speed operation without problems, increasing the efficiency of the machine. .

Moreover, the plate member 3 that is perpendicular to the knife and parallel to the horizontal needle does not pose much of a problem in terms of strength and can be made quite thin, so the pitch at which it is attached to the knife can be made quite small, and the vertical nail 2 and horizontal needle 6 thereby The arrangement pitch of the cards and the corresponding perforation pitch of the cards can be made considerably smaller.

Furthermore, the knife 1 is not damaged, the plate member 3, the vertical nail 2, and the horizontal needle 6 are removed.
It will be easily understood that pitch adjustment and replacement/repair are easy.

In addition, in the figure, 12 is a bottom plate, and 13 is a hanging cord.

Next, in the second embodiment shown in FIGS. 10 to 12, the plate member 3 attached perpendicularly to the knife 1 is shifted by half the attachment pitch between the pair of knives 11 in a staggered manner. It exists in the form of

As shown in FIG. 13, the plate-like member 3 has two upper and lower gauges at different heights protruding from the sides, respectively, near the tip of the part that overhangs on both sides of the knife 1. Four entraining members 5 are provided.

The entraining member 5 is made of a tongue-shaped body formed by punching out and bending a part of the plate-like member 3, and has a space above it for a hole punched in the plate-like member 3 by punching.

Plate members 3, 3 from each of the knives 1, 1 are inserted between the pair of knives 1, 1.
The parts that project in opposite directions overlap each other when viewed in plan, so that adjacent parts of the projecting parts protrude opposite each other, one above and the other below. The two driving elements 5, 5 are located in the same position without deviation in the direction transverse to the knife and serve to drive the peg 2 located between them.

In this case, the driving element, which projects on the opposite side with its projecting part, serves to drive the adjacent nail.

Therefore, the vertical nails 2 are arranged so that one nail exists for every half pitch of the attachment pitch of the plate member 3 to the knife 1.

As shown in FIG. 14, the vertical nail 2 is provided with a horizontally opposite side, which corresponds to the two upper and lower driving members 5, 5, which do not have the above-mentioned deviation in the knife cross direction, for driving the vertical nail 2. The two protruding main hooks 4, 4 are connected to each other at the same location without being shifted from side to side.
A tongue-like body is provided on one side edge of the upper end portion with a vertical deviation, and a portion of a vertical nail is bent, and a space is formed below the main hook 4.

When the main hook 4 is received and engaged by the driving member 5 in carrying the vertical nail 2, the vertical nail 2 is drawn to and comes into contact with the plate member 3, as shown in FIGS. 15 and 16.

Also, by the pressure adjustment control movement of the vertical nail 2 in the direction parallel to the plate-like member 3 and intersecting the knife 1 by the horizontal needle 6, the
As shown in FIG. L7 and FIG. 18, the main hook 4 has a free range 11 formed in a plane perpendicular to the length direction of the knife 1 that exists due to the overhang interval between the knife 1 of the plate member 3 and the driving member 5. will be moved to

These points are the same as the first embodiment.

Next, in the third embodiment shown in FIGS. 19 to 21, the plate-like members 3 are arranged in a staggered manner between the pair of knives 1, 1 and are shifted by half the pitch of attachment to the knives when viewed in plan. The nails 2 are arranged to be present at every half pitch of the attachment pitch of the plate member 3 to the knife.

In order to carry the vertical nail 2, between the pair of knives 1, 1, the portions of the adjacent plate members 3, 3 that project in opposite directions to each other protrude laterally in opposition to each other. The entraining members 5, 5 are provided so that they can be brought into alignment with each other, superimposed on each other, without any cross-direction deviation or difference in level between the knife and the knife.

As shown in FIG. 22, the plate-like member 3 is provided with a total of four entraining members 5, two on the lower edge of each of the tips of the portions that protrude on both sides of the knife 1, so that they mutually form the shape of a square. It is being

Note that these driving members 5 are not limited to the lower edge of the plate-like member 3;
It may also be provided between the lower edge and the upper edge.

The vertical nail 2 has two main hooks 4, 4 as shown in FIG.
However, it is an integral object that protrudes completely symmetrically from the side of the vertical nail 2 without any deviation from left to right or up and down, and mutually forms an arrowhead shape or an inverted chevron shape. , are pivotally attached to the upper end of the vertical peg 2 so as to be tiltable about a pivot shaft 14 that is perpendicular to the projecting direction, integrally located between the two.

In order to recover from the integral tilting of both the main hooks 4, 4 around the pivot axis 14, the boss part at the center of the tilting of both the main hooks 4, 4 is provided with a side of the vertical nail 2 from the support part 15 below. The upper end of a thin bar spring 16 extending vertically along the section is fitted and engaged.

The upper end of the bar spring 16 is as shown separately in FIG.
V formed on the end face of the rotation center boss portion of both main hooks 4, 4
It may be made to draw and touch the recess 17 of the character shape.

The bar spring 16 may be replaced with a suitable spring such as a coil spring for restoring both main hooks 44 from tilting.

Providing this spring 16 is advantageous against vibrations and in high-speed operation, but if both main hooks 4, 4 are accurately balanced around the pivot 14, this alone will have a restoring effect from tilting. Not necessarily necessary.

In this embodiment, as shown in FIGS. 25 and 26, when the main hook 4 of one of the vertical nails 2 is received and engaged with the driving member 5 of the plate-shaped member 3 of one of the knives 1 belonging to it, , the engaged main hook 4 tilts upward about the pivot axis 14 due to the tensile load applied to the vertical nail 2, which causes the other free main hook 4 to simultaneously and integrally tilt downward. and comes into contact with the side surface of the vertical nail 2.

Therefore, unlike the first and second embodiments, the knives 1, 1 pass each other in their downward movement tendency without the vertical nail 2 coming into contact with the plate member 3 and without any tilting or bending. The range of movement of the entraining member 5 of the plate-shaped member 3 of the other rising knife 1 to which the other free main hook 4 belongs, even if it is not pushed and controlled by the cross needle 6 up to that point. It is not retracted and released from the receiving engagement and is not unintentionally taken to the upper shed position.

Therefore, it works reliably, is extremely advantageous for high-speed operation, and has extremely high machine efficiency.

In this case, the spring 16 serves to recover from the tilting movement when the main hooks 4, 4 are released from the receiving engagement by the entraining member 3.

Next, in the fourth embodiment shown in FIGS. 29 to 31, the plate member 3 is placed at the same location between the pair of knives 1 and 1 by matching the attachment pitch, and the vertical nail 2 is placed between the plate member 3. It is arranged so that it exists for each attached pitch.

The opposing sides of the portions of the plate members 3, 3 that are adjacent to each other in the diagonal direction between the pair of knives 1, 1 for carrying the vertical nail 2 and protrude in opposite directions from each other. Even though the two entraining members 5, 5 projecting in the direction can be in the same state at the height level, there is a displacement between them in the direction transverse to the knife when viewed in plan.

The two main hooks 4, 4 of the vertical nail 2 are pivotally attached to the vertical nail 2 so as to be able to tilt integrally.

In these respects, this embodiment is like a combination of the first embodiment and the third embodiment.

As shown in FIG. 32, the plate-shaped member 3 has a groove at the lower edge (not necessarily the lower edge) of the tip of the part that overhangs on both sides of the knife 1, at the same height level and opposite to each other. A protruding driver element 5 is provided.

As shown in FIG. 33, the vertical nail 2 has two main hooks 4 4 which protrude sideways in opposite directions at the same height level, and is connected between the two aforementioned driving members 5 and 5 for driving the vertical nail 2. The pivot shaft 14 in the direction perpendicular to the projecting direction is integrally formed into a reverse ■ shape with a shift left and right in response to the shift.
It is connected to the upper end of the vertical nail 2 and pivoted to the upper end of the vertical nail 2 so as to be tiltable about the pivot shaft 14.

It is also provided with a spring 16 for restoring the two main hooks 4, 4 from their integral tilting motion.

In this embodiment, as shown in FIGS. 34 and 35, when one main hook 4 of the vertical nail 2 is received and engaged with one of the driving members 5 belonging thereto, the load applied to the vertical nail 2 Due to the simultaneous integral tilting of both main hooks 4, 4, the vertical nail 2 is prevented from coming into contact with the plate member 3, and the other free main hook 4 is retracted and released from the range of movement of the other driving member 5 belonging thereto. This embodiment is similar to the third embodiment in this respect, except that the two main hooks are shifted from side to side.

As shown in FIGS. 27 and 28, and FIGS. 36 and 37, the third embodiment and the fourth embodiment refer to the push by the horizontal needle 6 of the vertical nail 2 in the direction orthogonal to the knife. In a dynamic adjustment control movement, the main hook 4 is moved into the free range 11 due to the overhanging distance between the knife 1 of the plate-shaped member 3 and the driving member 5, and the vertical nail 2 is released from the movement of the pair of knives 1, 1. There is no lifting, and this action is carried out with a slight tilting of the vertical peg 2.
