One end thereof presses against the lower surface of the other side of the rocking plate 88 and acts to maintain the fit between the fitting hole 90 and the abutment piece 7R at all times.

Reference numeral 93 denotes a horizontally long shaft rod supported rotatably around a horizontal axis at the rear of the fixed support plate 16; A push-down piece 94 is fixed to the upper side surface against the spring to rotate the swinging plate 88 and disengage the fitting relationship between the fitting hole 90 and the abutment piece 70, and the other end A movable guide piece 96 is fixed to the front surface of the moving part body 40 so as to sandwich the moving part body 40 between it and a fixed guide piece 95 on the needle bed, and can be detached by rotation.

The connection between the movable guide piece 96 and the front surface of the moving body 40 is as follows:
Normally, the spring 92 is maintained by applying upward elastic force to the push-down piece 94 via the swing plate 88.

In the figure, reference numeral 97 denotes a starting protrusion that is detachably supported by the moving body 40, and as shown in FIG. The entire structure is made of an elastic hard elastic material such as hard rubber.

The activation protrusions 97 are arranged at regular intervals on the moving body 40 (at each operating length necessary for the knitting needle selection action in a specific range, which will be described later).
Each of the small protrusions 98 is fixed by being pushed into a pair of upper and lower locking holes 99, which are bored over the entire circumference (at least only in the rear straight portion), against the elastic action of the locking holes 99.

When the actuating protrusion 97 enters between the fixed and movable guide pieces 95 and 96 due to the movement of the moving body 40, it moves the movable guide piece 96 forward and moves the movable guide piece 96 forward. The rotation of the rod 93 and the pressing down action of the rocking plate 88 by the pressing piece 94 are performed.

When the driving force of the circulating drive tree is transmitted to the needle selection body 6 through the rear operating body 26 at the driving position a and the corresponding operating body 23, and when the sorting device passes outside the range, A specific range needle selection driving device is configured to prevent the driving force from being transmitted to the needle selection unit 6.

Further, the small protrusion 98 of the starting protrusion 97 and the locking hole 99 of the moving part body 40 allow the relative arrangement of the moving part body 40 and the specific range needle selection drive device (particularly the starting protruding piece 97). By relatively shifting the moving body 40 in the direction of movement, the shifting device causes the driving force to move when passing through a range of a similar size that is linked to the knitting needle pinch from the specific range of the driving force. configured.

In the figure, reference numeral 100 denotes a carriage mounted on the upper surface of the needle bed so as to be able to slide from side to side, and on the rear side thereof, a pair of connections are fitted and connected to connection holes 101 at specific positions in the front straight portion of the movement body 40. A piece 102 is provided, and as the piece 102 slides left and right, the moving body 40 is rotated forward and backward.

On the lower surface of the carriage 100, there are, for example, well-known front and rear partition plates 103, 104 and a knitting cam 105 that can constitute two front and back passages for so-called two-color simultaneous knitting as shown in FIG. , Semi-retreat cam 106 Back-and-forth swing cam 107, 10
8. In addition to the switching cam 109, the fixed cam 110, etc., the following wing selection device 111 is provided on both the left and right sides of these cam groups.

That is, it is a forward cam that passes behind the knitting cam 105 at 112 in the figure and advances the knitting needle 20 butt a certain distance after the completion of t knitting.

113 is the knitting needle 20 advanced by the advance cam 111.
This is a lowering cam that lowers the butt and brings the knitting needles 2 into relation to the needle selection body 6.

Reference numeral 114 denotes a needle selection cam that is arranged at an angle on the outside of the reduction cam 113, which allows the knitting needle 20 butt at the reduction position, which is locked to the needle selection portion 7 of the needle selection unit 6 by reduction, to pass through.
After being once lowered, the knitting needle 20 butt, which has returned to the upper position without being retained by the needle selection portion 7, is retreated.

Reference numeral 115 denotes a sorting difference enlarging cam that advances the knitting needle 20 butt which has passed below the sorting cam 114 and returned upward.

Knitting needles 2 sorted backwards by the sorting device consisting of the above
The butts of the knitting needles 2 selected forward at the knitting preparation position X on the 0-butt needle bed 1 are guided to the needle selection position Y just before the stitches come off (the state in which the stitches are suspended above the open lunch). .

This embodiment is configured as described above.

Below, a specific range (a group of 24 consecutive knitting needles in this example) of the working knitting needle section (20 knitting needle sections at the knitting preparation position The needle selection action will be explained.

That is, the starting protrusion 97 on the moving body is set in advance so that it 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. The piece 97 is fitted and locked into a predetermined locking hole 99 of the movement part body ura.

First, from the yoke in which the carriage 100 passes through the active knitting needle section and the moving member tree 40 is rotating in the direction of the arrow shown in FIG. 3, the carriage 100 is slid in the opposite direction. When the moving direction of the moving body 40 is changed to the direction opposite to the arrow shown in FIG.
1 reaches the end of the moving knitting needle group, the feed cam 49
The selection body 11 is transferred by a predetermined amount, and a new needle selection operation signal train corresponds to the reading section 28 of the rear effector 26.

Next, the carriage 100 approaches the working knitting needle section, and just before the sorting device 111 on the rear side in the sliding direction of the carriage approaches a specific range, the activation protrusion 97 on the moving body is fixed and the movable guide piece 95 .96 and its movable guide piece 9
The swing plate 88 swings in conjunction with the movement of the contact piece 7.
0 and the insertion hole 90 are separated.

As a result, the actuating piece 62 on the rotating wheel 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, as the pressing down of the alignment body 36 is released by the switching cam 75, all the rear actuating bodies 26 move upward toward the drive position a. .

However, at this time, one of the release cams 86 of the release plate 82 is
The rear actuator 26 corresponding to the auxiliary alignment row 139B pushed down by B remains in the non-drive position c.

As a result of the upward movement of the rear operating body 26, the rear operating body 26 corresponding to the through hole 12 of the selection body 11 is placed in the drive position a, as shown in FIGS. The rear effector 26 corresponding to the hole 13 is arranged at the intermediate position b.

At the same time that the rear operating body 26 that moves upward is placed at the driving position a, the operating portions 27 of the rear operating body 26 are rotated in order from the rearmost operating body 26 at the end, as shown in FIG. 12A. ，
Coinciding with and synchronously with the corresponding cam piece 33 of the driving body 31, the knitting needles are sequentially rolled down by the rolling down cam 113 starting from the knitting needles at the ends of the specific range.

In this case, for example, when the rear effector 26 and the corresponding knitting needle 2 arranged at the drive position a, the action portion 27 of the rear effector 260 is rotated by the cam piece 33 of the circulation actuator 31. Through the swinging of the front actuating body 23, the needle selection body 6 is placed in the needle selection action position, and just before this placement, the corresponding knitting needle 2 is pressed down and placed in the same pressed 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 114. This is maintained by the engagement between the rear operating body 26 and the cam piece 33.

When the engagement is disengaged, the needle selection body 6 returns to the needle selection inactive position, so that the knitting needles 2 at the lowered position are disengaged from the needle selection portion 7 and rise, and the selection is performed. Difference enlargement cam 115
The needle selection position Y is derived by

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 needle selection non-operating position, and therefore, even if the corresponding knitting needle 2 is once pushed down, that knitting needle 2 is not locked in the needle selection portion 7 and therefore rises again before the selection cam 1140. Then, it is retracted by the sorting cam 114 and guided to the knitting preparation position X.

In this way, the knitting needles 2 in a specific range are sequentially sorted starting from the ends thereof, and the respective rear actuating bodies 26 corresponding to one auxiliary alignment body 39A are sequentially driven and non-driven by the respective cam pieces 33, Immediately after the knitting needles 2 corresponding to the rear operating bodies 26 are sequentially sorted, the large-diameter cam surface 79 to the small-diameter cam surface 78 of the operating cam 76 correspond to the engagement pin 81 of the rotating lever 80. Along with this, (the FIG. 3 reference release plate 82 moves to the position shown by the two-dot chain line in FIG. Each rear actuating body 26 is in the non-driving position c
Instead of being located at
is allowed to move upward and is driven by the selection body 11, each intermediate position a
, b (see Figure 12b).

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

As this 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 alignment body 36 is pushed down by the switching cam 75,
All the rear effecting bodies 26 are simultaneously placed in the non-driving position c.

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 in the same direction coincides with the cam piece 33 on the same direction side, but each rear actuating body 26 corresponding to the auxiliary alignment body 39A on the same direction side has already been placed in the non-driving position c. Therefore, there is no problem of further knitting needle selection, and the knitting needle selection can be performed accurately 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 turned back and slid, the rear actuating body 26 is driven and de-driven from the other auxiliary aligning body 39b side in accordance with the same procedure as described above, and the knitting needle group in a specific range is also moved as described above. The items are sorted sequentially starting from the opposite end.

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

Now, since it is possible to shift the specific range that performs the above-mentioned knitting needle selection action in the lateral direction in relation to the knitting needle pitch, this will be explained below.

That is, in the case of this embodiment, the activation protrusion 97 is removed from the locking hole 99 on the moving body 40 that is currently locked, and the activation protrusion 97 is removed from the locking hole 99 adjacent to the right side in FIG. 99, the specific range where the knitting needle selection action is performed is:
The position shifts to the right side by one needle selection cycle (a group of 24 knitting needles), and the needle selection action is performed in exactly the same manner as described above.

Further, the activation protrusion 97 is further inserted into the appropriate locking hole 99 in the left or right direction.
By replacing the needle with the needle, the specific range in which the knitting needle selection action is performed can be shifted to the left or right by an appropriate needle selection period.

According to this embodiment, the specific range is shifted by fitting the activation protrusion 97 into each of the locking holes 99 on the moving body 40, but instead of this, for example, , the activation protrusion 97 is always fixed to the moving body 40,
This may be achieved by rearranging the fixed guide piece 95 and the movable guide piece 96 together in the direction of movement of the moving body 40.

Furthermore, according to this embodiment, when the specific range is adjusted, it is performed every one needle selection cycle (every 24 knitting needle groups), but this is made smaller, that is, when the knitting needles are It may be done every other needle or every few needles, or conversely, it may be done every group of knitting needles that is larger than the number of knitting needles for the one needle selection cycle. For example, the locking holes 99 may be formed in the moving body 40 with a finer pinch or with a coarser pitch.

A second embodiment embodying the present invention will be described in detail below with reference to FIGS. 13 to 18 (A to 18).

Note that the same names and symbols will be used loosely for the same parts as in the first embodiment.

The related structures of the selection body 11, feed drum 17, rear operating body 26, circulating drive body 31, guide shaft 42, etc. shown in FIG. Since this embodiment is the same as the first embodiment, the explanation thereof will be omitted, and only the different parts will be explained below.

That is, as shown in FIG. 15, 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 movement section book indicated by 40 in the figure. A rack 116 is provided as a power source necessary for sorting the knitting needles, and connecting holes 117 are bored around the entire circumference at intervals corresponding to one needle selection cycle (a group of 24 knitting needles).

In the figure, reference numeral 118 denotes a rotary shaft vertically pivoted on a fixed base 119 on the rear side of the fixed support plate 16, and at its upper end there is a power intake gear that meshes with the rasok 116 of the moving body 40 and rotates. 120 is fixed, and a power transmission gear 1 is attached to the lower end.
21 is fixed.

In the figure, 122 is an elongated plate-shaped switching body, and the fixed support plate 16
Several guide pieces 1230 fixed to the guide hole 124 are fitted and supported to enable left and right movement.

The switching body 122 is provided with a rack-shaped engagement hole 125 that meshes with the power transmission gear 121 for a length corresponding to the length driven by the rack 116. An upward motion permitting portion 126 of 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 1'27 that guide the upward and downward movements of the rear operating body 26
is formed, and furthermore, on the left and right of the upward motion allowing portion 126,
A holding portion 128 is provided that has a length that can cover all the groups of rear effecting bodies 26 and holds the rear effecting bodies 26 at the non-driving position C.

The length V of the upward motion allowing portion 126 is equal to the distance W between adjacent needle selection portions 7 of each needle selection member 6 (see FIG. 11).
It is said to be approximately equal to or slightly larger than the required length of needle selection 2 (18th
(See Figure A, the range from when the knitting needle 20 butts begin to be pressed down until the sorting of the bats is completely completed), and moreover, the driving position i! It has a length that sufficiently covers the operating length from when the rear operating body 26 of a is started to be driven by the corresponding cam piece 33 until it is completed.

This particularly eliminates erroneous needle selection where the knitting needles 2 locked on the needle selection part 7 of the needle selection unit 6 are released from the needle selection part 7 before the selection cam described later and are sorted backwards. I can do it.

Furthermore, as shown in FIG. 17, the right-hand end of the guide piece 120 has a guide hole 121 at its entrance to facilitate fitting of the switching body 122 therein. A tapered guide portion 129 is formed.

By sliding the needle selection carriage 130,
Immediately before the lowering cam 134 of the sorting device 133 approaches the specific range, the ratchet 116 on the moving body engages with the power intake gear 120, as shown in FIG. It is moved laterally in the direction of the arrow shown in FIG. 18A.

Along with this lateral movement, the upward movement permitting portion 126 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 the driving and non-driving of each of the rear actuating bodies 26, the needle selection portion 7 of each corresponding needle selection body 6 locks or does not lock the reduction knitting needle 2. The locked knitting needles 20 butts are sorted forward, and the unlocked knitting needles 20 butts are sorted backwards.

In this way, the knitting needle selection fraud proceeds sequentially, and the rear actuating body 26 that is driven and undriven first is sequentially placed in the non-driving position C by the holding part 128 on the opposite side (the first
8), when the holding portion 128 positions the rear operating body 26 at the opposite end to the non-driving position C, the rack 116 and the power intake gear 120 are disengaged and the switching is interrupted. Lateral movement of body 120 stops.

Also, the needle selection carriage 130 is folded back and slid to move the moving body 40.
When is moved in the opposite direction, the lasso 116 meshes with the power intake gear 120 from the opposite side to the switching body 12.
2 moves in the opposite direction, and along with this, the knitting needles 2 in the specific range are sequentially sorted from the end opposite to the above in the same manner as above.

In order to shift the specific range in which the above-mentioned knitting needle selection action is performed, after operating the operating piece 140 and disengaging the connecting pin 139 from the connecting hole 117 of the moving body 40, the needle selecting carriage 13 is moved.
0 and insert the connecting pin 139 into the desired connecting hole 117.
to be inserted into.

This allows the specific range to be adjusted to the needle selection carriage 130.
can be shifted in the sliding direction by a desired needle selection period, and a group of knitting jumps within this range can be selected by the same method as described above.

Now, regarding the rank on the moving body 40 of this embodiment,
The present invention may be modified to those shown in FIGS. 19 to 21, which show a third embodiment embodying the present invention.

That is, 142 in the figure is a single flexible rack plate made of a bullet plate, which replaces the rack 116 of the second embodiment, and has an operating length that provides the power necessary to select a group of knitting needles in a specific range. death,
A downward U-shaped engagement groove 143 is provided on the left and right sides of the lower surface, and an inclined surface 144 is provided on the left and right ends of the upper surface.

A stepped locking pin 145 is implanted in the moving body 40 so as to maintain an interval between both engaging grooves 143 of the rank plate 142, and a pair of adjacent stepped locking pins 145 are provided with a stepped locking pin 145. On the other hand, the rack plate 142 is supported by the moving body 40 by fitting the two engaging grooves 143 into each other.

Reference numeral 146 in the figure denotes a rack guide plate, which is fixed in the needle bed at a position corresponding to the power intake gear 120 and engages with the upper and rear surfaces of the rank plate 142 supported by the moving body 40.
The rack plate 142 is restrained on the moving body 40.

Note that the engagement groove 143 of the rank plate 142 and the moving body 4
By means of the stepped locking pin 145 on the 0, a shifting device having the same function as in each of the embodiments described above is constructed.

Therefore, in order to shift the specific range in which the knitting needle selection function is performed, it is only necessary to fit the engaging groove 143 of the rack plate 142 into a desired one of the stepped locking bins 145.
The knitting needle selection action in the specific range is performed in accordance with the second embodiment.

As described in detail above, the present invention includes a plurality of needle selection sections each having a needle selection section for braiding each knitting needle, and a plurality of needle selection sections connected to the needle selection section and divided into selection sections. An operating body, a circulating drive body that drives the operating body at one division position in a fixed order to move the corresponding needle selection body, and a circulating drive body that moves the corresponding needle selection body in synchronization with the driving and non-driving of the operating body by the circulating drive main body. In a needle selection device comprising a needle selection device on a carriage that selects needles by associating knitting needles with a needle selection unit, in particular, the selection device on the sliding carriage passes through a specific range of the operating knitting needle section. transmitting the driving force of the circulation drive body to the needle selection body through the actuation body at the one sorting position in relation to the movement of the movement unit only when the selection device passes outside the range; In some cases, a specific range nail selection drive device is provided that prevents the driving force from being transmitted to the needle selection body, so there is no need to take the trouble of arranging the knitting needle group in the specific range to another position or changing the course in advance. 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, between each of the operating bodies and the carriage, the relative arrangement of the moving body and the carriage or the specific range needle selection drive device is relatively shifted in the direction of movement of the moving body,
The present invention is equipped with a shifting device that transmits the driving force to the needle selection body when the selection 8+1 position passes through a range of a similar size that is shifted from the specific range in relation to the knitting needle pitch. It has excellent effects such as being able to obtain more diverse needle selection patterns by arbitrarily shifting the specific range without fixing it.
