Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a needle selection device for a knitting machine that selects knitting needles only in a specific range of an operating knitting needle section and does not select knitting needles in other ranges.

Conventionally, in this type of needle selection device, for example, a knitting needle operation plate that can cover a specific range of knitting needles is placed on the needle bed, while a carriage that slides on the needle bed is provided with a carriage that slides on the needle bed to operate the knitting needles. Some knitting machines are equipped with means for operating a plate to advance the knitting needles corresponding to the knitting needle operation plate, and a sorting means for sorting out the advanced knitting needles.

In addition, as another example, by sliding the carriage,
There has also been proposed a device in which the course of the knitting needles in the specific range is changed using a course changing cam on the carriage so that a sorting action is applied only to the knitting needles in that specific range.

Reference numeral 113 denotes a sorting difference enlarging cam that advances the knitting needle 20 butt which has passed below the sorting cam 112 and returned upward.

The knitting needles 20 butts sorted backward by the above sorting device are guided to the knitting preparation position the needle selection position Y (state).

This embodiment is configured as described above.

Below, a specific range (in this example, a group of 24 consecutive knitting needles) of the working knitting needle section (the section of the knitting needle 2 at the knitting preparation position The needle selection action will be explained.

That is, the moving body 40 is set in advance so that the protrusion 91 on the moving body enters between the fixed and movable guide pieces 95 and 96 immediately before the sorting device on the rear side in the sliding direction of the carriage approaches the specific range. Projection 91, carriage 98, fixed and movable guide piece 95
, 96, etc. are set in advance.

First, from a state in which the carriage 98 passes through the working knitting needle section and the moving body 40 is rotating, for example, in the direction of the arrow shown in FIG. 3, the carriage 98 is slid in the opposite direction to start the movement. When the direction of movement of the member 40 is changed to the direction opposite to the arrow in FIG. After being transferred by a predetermined amount, a new needle selection operation signal train corresponds to the reading section 28 of the rear operating body 26.

Next, the carriage 98 approaches the working knitting needle section, and just before the sorting device 109 on the rear side in the sliding direction of the carriage approaches a specific range, the protrusion 91 on the moving body is fixed, and the movable guide pieces 95, 96 are fixed. As the movable guide piece 96 moves, the swing plate 88 swings and the contact piece 70 and the fitting hole 90 are separated.

As a result, the actuating piece 62 on the rotating shaft 60, which is already rotating in the direction opposite to the arrow shown in FIG. 3, rotates the first and second cam plates 67, 72 and the rotating shaft 64 in the same direction. The rotation continues until the abutment piece 70 abuts the stopper 74 from the opposite side and is fitted into the other fitting hole 90.

At the beginning of the rotation of the rotation shaft 64, the first release member 7
5, all the rear actuating bodies 26 move upward toward the drive position a as the depression of the first switching body 36 is released.

However, at this time, one of the release cams 86 of the release plate 82 is
The rear actuating body 26 corresponding to the second switching body 39B pushed down by B is placed in the non-driving position C as it is.

As a result of the upward movement of the rear operating body 26, as shown in FIG. 10A. As shown in the figure, the rear actuating body 26 corresponding to the through hole 12 of the selection body 11 is located at the drive position a, and
The rear actuator 26 corresponding to the non-porous portion 13 is arranged at the intermediate position b.

At the same time that the upwardly movable rear operating body 26 is placed in the driving position a, the operating levers 27 are driven in a circular manner starting from the rear operating body 26 at the end, as shown in FIG. 10A. Coinciding with and in synchronization with the corresponding cam piece 33 of the body 31, the knitting needles 2 at the ends of the specific range are sequentially rolled down by the rolling down cam 111.

In this case, for example, when the rear effector 26 and the corresponding knitting needle 2 disposed at the drive position a, the action portion 27 of the rear effector 260 is rotated by the cam piece 33 of the circulation drive body 31. The needle selection body 6 is placed in the needle selection action position through the swinging of the front actuating body 23, and immediately before this placement, the corresponding knitting needle 2 is lowered and placed in the same pressing position.
The needle selection portion 7 of the needle selection unit 6 engages with the reduction knitting needle 2, and the knitting needle 2 is locked in the reduction position, and this locked state remains until the reduction knitting needle 2 passes the selection cam 112. This is maintained by the engagement between the rear operating body 26 and the cam piece 33.

When the locking is released, the needle selection body 6 returns to the non-selecting position, so that the knitting needles 2 in the rolled-down position are removed from the needle selection portion 7 and rise, thereby reducing the selection difference. The magnifying cam 113 guides the needle to the needle selection position Y.

On the other hand, regarding the rear operating body 26 disposed at the non-driving position C and the corresponding knitting needles 2, since the rear operating body 26 is not driven by the cam piece 33 of the circulating drive body 31, the corresponding needle selection section The body 6 remains in the non-operating position for needle selection, and therefore, even if the corresponding knitting needle 2 is once pushed down, that knitting needle 2 is not retained by the needle selection portion 7 and rises again in front of the selection cam 1120. Then, it is retracted by the sorting cam 112 and guided to the knitting preparation position X.

In this way, the knitting needles 2 in a specific range are sequentially sorted starting from those at the ends thereof, and each step actuating body 26 corresponding to one second switching body 39A is sequentially driven and non-driven by each of the cam pieces 33. , and immediately after each knitting needle 2 corresponding to each rear actuating body 26 is sequentially sorted, the large diameter cam surface 19 to the small diameter cam surface 18 of the operation cam 160 correspond to the engagement pin 81 of the rotating lever 80. Along with this (see FIG. 3), the release plate 82 moves to the position shown by the two-dot chain line in FIG. Instead of each corresponding rear actuating body 26 being placed in the non-driving position C, the other second switching body 3
9B is released, and the corresponding rear actuating bodies 26 are allowed to move upward, and are divided into drive and intermediate positions a and b by the selection body 11 (see FIG. 10).

Thereafter, the remaining knitting needle selection operations in the specific range are continued and completed in accordance with the above-mentioned procedure.

As the process ends, the corresponding cam piece 33 at the extreme end passes through the rear operating body 26 at the extreme end, and at the same time,
Since the first switching body 36 is pushed down by the first release body 75, all the rear effecting bodies 26 are placed in the non-driving position C at the same time.

Note that when the cam piece 33 at the farthest end passes through the rear operating body 26 at the farthest end, the rear operating body 26 at the farthest end on the opposite side
6, the cam piece 33 at the end of the same direction side comes to match, but each rear actuating body 26 corresponding to the second switching body 39A on the same direction side is already placed at the non-driving position c. Therefore, there is no trouble that a knitting needle sorting operation is performed further, and the knitting needle sorting operation can be accurately carried out only in the specific range.

In the manner described above, the knitting needle selection action in a specific range is performed.

When the carriage 98 is slid back and forth, the knitting needle group in a specific range is caused to move in and out of the rear actuating body 26 from the other second switching body 39B side in accordance with the same procedure as described above. They are also sorted sequentially starting from the end opposite to the above.

Incidentally, the knitting needle group selected as described above is used for pattern knitting when the carriage turns back and slides.

A second embodiment embodying the present invention will be described below with reference to FIGS. 11 to 15 (a) to (b).

Note that the same names and symbols as in the first embodiment are used for the same parts as in the first embodiment.

The selection body 11, feed drum 17, rear operating body 26, circulation drive body 31, guide wheel 42, etc. shown in FIG.
etc. are the same as those in the first embodiment, so a description thereof will be omitted, and only the different parts will be described below.

That is, as shown in FIG. 13, two groups of knitting needles (24 needles) in a specific range of the same size as in the first embodiment are placed on the upper surface of the specific position of the moving body indicated by 40 in the figure. A rack 114 is provided as a power source necessary for sorting.

In the figure, reference numeral 115 denotes a rotating shaft vertically pivoted on a fixed base 116 on the rear side of the fixed support plate 16, and at its upper end is a power intake gear 117 that meshes with the rack 114 of the moving body 40 and rotates. is fixed, and a power transmission gear 11 is attached to the lower end.
8 is fixed.

In the figure, reference numeral 119 denotes a switching body in the form of an elongated plate, and the fixed support plate 16
Several guide pieces 1200 fixed to the guide holes 121 are fitted into and supported to enable left and right movement.

The switching body 119 is provided with a rack-shaped engagement hole 122 that meshes with the power transmission gear 118 for a length corresponding to the length driven by the rack 114, and the rear operating body 26 is provided in the left and right intermediate portions of the switching body 119. An upward motion permitting portion 123 having a predetermined length V that permits upward movement in the direction of the drive position a, and a pair of left and right inclined surfaces 124 that guide the upward and downward movements of the rear operating body 26 are formed. The left and right sides of the motion allowing portion 123 have a length that can cover all the groups of rear effecting bodies 26,
A holding portion 125 for holding the rear operating body 26 in the non-driving position C is provided.

The length V of the upward motion allowing portion 123 is determined by the distance W between adjacent needle selection portions 7 of each needle selection member 6 (see FIG. 9);
Or, is it approximately equal to the required needle selection length Z (see Fig. 15A, the range from when 20 butts of knitting needles begin to be pressed down until the selection of the batts is completely completed), which is approximately equal to this interval W?
It is slightly larger than this length, and has a length that sufficiently covers the operating length from when the rear actuating body 26 at the drive position a starts being driven by the corresponding cam piece 33 until it is completed.

By this, in particular, it is possible to eliminate erroneous needle selection where the knitting needles 2 locked to the needle selection part 7 of the needle selection unit 6 are released from the needle selection part 7 before the selection cam 1120 and are sorted backwards. I can do it.

Furthermore, the entrance portion of the guide hole 1210 of the right side portion of the guide piece 120 shown in FIG. 11 has a taper for smooth insertion of the switching body 119 as shown in FIG. A shaped guide portion 126 is formed.

This embodiment is configured as described above.

The knitting needle selection function in a specific range of the working knitting needle section will be explained below.

That is, in advance, the sorting device 109 on the rear side in the carriage sliding direction
The carriage 98, the moving member body 40, and the moving member body 40 are arranged so that the rack 114 on the moving member body 40 meshes with the power intake gear 111 immediately before the carriage (which may have a sorting action on the front side in the sliding direction of the carriage) approaches the specific range. The arrangement of the power intake gear 117 and the like is set in advance.

By sliding the carriage 98, just before the sorting device 109 on the rear side in the sliding direction approaches the specific range, the rack 114 on the moving body is moved, as shown in FIG. It meshes with the power intake gear 117, thereby causing the switching body 119 to move laterally in the direction of the arrow shown in FIG. 15A.

Along with this lateral movement, the upward movement permitting portion 123 sequentially allows the upward movement of the rear effecting body 26 in the direction of the drive position a, starting from the rearmost actuating body 26 at the end, and prevents the upward movement. The permitted rear actuating bodies 26 are divided into a drive position a and an intermediate position b by the selection body 11, and only the rear actuating bodies 26 divided into the drive position a are driven by the cam piece 33.

Furthermore, in synchronization with each of the rear actuating bodies 26 being driven and non-driven, the needle selection portion 7 of each corresponding needle selection body 6 locks or does not lock each reduction knitting needle 2; The locked knitting needles 2 are sorted forward, and the unlocked knitting needles 2 are sorted backward.

In this way, the knitting needle selection action progresses sequentially, and
The rear actuating body 26 that was driven and undriven first is sequentially placed in the undriven position C by the holding part 125 on the opposite side (the 15th
), so that when the holding part 125 disposes the rear operating body 26 at the opposite end in the non-driving position C, the rack 1
14 and the power intake gear 117 are disengaged, and the lateral movement of the switching body 119 is stopped.

Further, when the carriage 98 is turned back and slid to move the moving body 40 in the opposite direction, the rack 114 meshes with the power intake gear 117 from the opposite side, and the switching body 119 moves in the opposite direction. Along with this, the knitting needles 2 in the specific range are sequentially sorted from the end opposite to the needles 2 in the same manner as described above.

A third embodiment embodying the present invention will be described below with reference to FIGS. 16 to 18.

Note that the same names and symbols as in each of the above embodiments are used for the same parts as in each of the above embodiments.

Although not shown, in this embodiment, related structures such as the selection body 11, the feed drum 17, the guide shaft 42, the rotation shaft 46, etc. are similar to those of the previous embodiment.

Particularly different parts will be explained below. In the figure, reference numeral 127 denotes a front actuating body in place of the front actuating body 23 of each of the above embodiments, each of which is constituted by a linear elastic body that can be elastically bent.
Usually, it has enough strength to move the needle selection member 6 from the needle selection non-active position to the active position without bending.

These front actuating bodies 127 are connected to the needle selection body 6 in the same manner as in each of the embodiments described above.

In the figure, reference numeral 128 denotes a bending body made of an elongated plate-like member, which can be moved within a small range in the left and right direction by means of a pair of fixed support rods 129 and a horizontally elongated hole 130 into which the support rods 129 are inserted. and is always pulled in the opposite direction to the needle selection body 6 by a spring 131,
A horizontally elongated hole 132 into which each of the front actuating bodies 127 is inserted is bored in the left and right intermediate portions thereof.

By moving the bending body 128 to one side (restricted position) against the action of the spring 131, the 18th
As shown in the figure, all the front actuators 127 are aligned on one side, and all the needle selection members 6 connected thereto are placed in the needle selection non-operating position.

In this state, even if the front actuator 127 is driven by the rear actuator 26 at the drive position a, the portion of the front actuator 127 that is rearward of the bending actuator 128 is elastically bent. The driving force is not transmitted to the corresponding needle selection unit 6.

Further, the bending body 128 is moved to the other side (
The 16th
As shown in the figure, all front actuators 127 are allowed to swing freely.

A generally belt-shaped actuating belt 133 that protrudes rearward is fixed to the moving part body indicated by 40 in the figure at least on the rear surface of the rear linear portion between both guide wheels, and approximately in the middle thereof, a specific A band-free section 134 having a working length necessary to carry out the sorting action of the knitting needles 2 in the range is provided.

In the figure, reference numeral 135 denotes a rotating rod pivotally attached to an upright plate 136 that is installed and fixed on the rear lower side of the needle bed, and its upper end is attached to the rear surface of the operating band 133 or the moving member body in the band absent area 134. 40
A roller 137 that rotates in contact with the rear surface of the
Further, the lower end portion is connected to the bending body 128 and has an approximately L shape.
It is brought into contact with a monopod erecting piece 139 of a crank 138 in the shape of a letter.

Further, the lower end of the rotating rod 135 is always provided with the spring 13.
10 elastic force is applied to the bending actuating body 128 and the crank 138.
through which the roller 13
7 is in pressure contact with the moving member body 40 at the rear surface of the operating band 133 or the band-free portion 134 .

As will be clear from the following explanation, the operating band 133, the band-free portion 134, the rotating rod 135, and the crank 138 are activated by the bending operation when the sorting device 109 on the carriage performs a knitting needle sorting operation in a specific range. It constitutes a switching body that places the body 128 in the unrestricted position and places the bending body 128 in the restrained position when the sorting device 109 passes outside the range.

In the figure, reference numeral 140 denotes a regulating plate fixedly arranged on the opposite side of the roller 137 with the moving body 40 interposed therebetween, and prevents the moving body 40 from deflecting against the pressing force of the roller 137.

This embodiment is configured as described above.

The knitting needle selection function in a specific range of the working knitting needle section will be explained below.

That is, in advance, just before the sorting device 109 on the carriage approaches a specific range, the carriage 98 and the moving member body 40 are moved so that the band absent portion 134 on the moving member body corresponds to the roller 137.
Set the placement and connection relationships such as.

Further, all the rear actuating bodies 26 are driven by the selection body 11, and are divided into intermediate positions a and b, and are driven and non-driven by the cam piece 33 of the circulation driving body 31.

By sliding the carriage 98, as shown in FIG. 11, while the roller 137 is in contact with the actuating band 133, the bending actuating body 128 is placed in the restraining position. Even when the front actuating body 127 is driven or de-driven, the driving force is not transmitted to the corresponding needle selection body 6.

Immediately before the sorting device 109 of the carriage 98 approaches the specific range, the band absent portion 134 corresponds to the roller 137, and the bending body 128 is placed in the unrestricted position.

As a result, the driving and non-driving power of the front actuating body 127 is transmitted to the corresponding needle selection unit 6, and in synchronization with this, the reduction knitting needles 2 are sorted forward or backward. It is done the same way as in the example.

Further, when the knitting needle 2 corresponding to the front operating body 127 at the endmost part corresponds to the position of the sorting cam 112, the roller 1
37 corresponds to the actuating band 133, so that the bending actuating body 128 is placed in the restraining position.

This completes the knitting needle selection action in the specific range.

Further, when the carriage 98 is turned back and slid, the group of knitting needles in the specific range can be sorted from the opposite side in the same manner as described above.

As described in detail above, the present invention includes a plurality of needle selection members each having a needle selection portion for braiding each knitting needle, and a plurality of needle selection members connected to the needle selection members and divided into selection members. A working body, a circulation driving body that drives the working body at one division position in a fixed order to move the corresponding needle selection body, and a corresponding movement in synchronization with the driving and non-driving of the working body by the circulation driving body. In a needle selection device comprising a selection device on a carriage that selects needles by associating knitting needles with a needle selection unit, in particular, the selection device on a sliding carriage passes through a specific range of the active knitting needle section. Only when the driving force of the circulation drive body is transmitted to the needle selection body through the actuation body of the one sorting position in relation to the movement of the movement body, and when the sorting device passes outside the range. Since the driving force is configured so as not to be transmitted to the needle selection unit, there is no need to place the group of knitting needles in the specific range in advance at other positions or change the course. By simply passing the carriage over the active knitting needle section, the selection operation of the knitting needle group in the specific range can be performed accurately.

Further, driving the action portion of each of the actuating bodies with respect to the circulating drive body,
At least the end portions located on one side and the other side of the boundary between the first switching body that switches to each non-driving position all at once and a specific pair of actuating bodies that are adjacent to each other in the order of being driven and non-driven. a pair of second switching bodies capable of individually switching the operating portion of the actuating body to the driving and non-driving positions, and the first switching body only when the sorting device on the sliding carriage passes through the specific range. a first release member that causes a switching member to freely displace the operating portions of all of the operating members in the drive position direction; and an action that corresponds to the one first switching member when the sorting device approaches the range. and a second release member for reversing the driving/non-driving positional relationship of the operating portions of the respective actuating bodies by switching the second switching bodies after the body is driven or undriven. Therefore, even though the circulation drive body is in circular motion, it is possible to very easily and accurately determine which actuation body is first driven or not driven in response to the circulation drive body. Accordingly, the boundary between the knitting needle group in the specific range and the knitting needle group in the other range can be clearly distinguished, and the knitting needle selection action in the specific range can be carried out more accurately. After the actuating body corresponding to the above is driven and de-driven, the actuating body remains in the non-driving position, which may cause malfunctions such as redundant driving of this actuating body by the circulation 6 driving body, etc. It is possible to reliably prevent needle selection errors caused by this.

Further, at least a portion of each of the actuating bodies connected to the needle selection body is usually constituted by a bendable elastic body having a strength sufficient to withstand movement of the needle selection body; In relation to the body part, a bending actuator is provided which is movable between restraint and non-restraint positions that do not allow the body part to bend or not to transmit the driving force to the needle selection body; , comprising a switching body that places the bending body in the non-restricted position only when the sorting device passes through a specific range, and places the bending body in the restrained position when the sorting device passes outside the range. Therefore, not only can the knitting needle selection action in the specific range be accurately performed by a simple operation as described above, but also because an elastic body is applied to the operating body, the overall related structure can be further simplified, and the It has various excellent effects such as being able to roughen the manufacturing and assembly accuracy.
