になっている。As one of the conventional needle selecting devices of this type, Japanese Examined Patent Publication Sho 47-34672
There is one disclosed in the publication. In this needle selection device, a first needle selection piece to which a strong spring is applied and a second needle selection piece to which a weak spring is applied and which can be adsorbed and held in a fixed position by an electromagnet are opposed to each other, and the electromagnet is turned off. In the case of, the knitting needle butt guided between the first and second needle selection pieces is guided forward by the hypotenuse of the first needle selection piece to push the second needle selection piece open While passing between the needle pieces, when the electromagnet is on, the second needle selection piece is attracted and held, so that the knitting needle butt is guided rearward by the hypotenuse of the second needle selection piece and While pushing the needle selection piece open, it passes between these needle selection pieces. Then, the knitting needle bats thus sorted forward and backward are sorted forward and backward by a single branch plate.

選別できる選針装置を提供することを目的とする。However, this conventional needle selection device has the following problems. (A) In addition to the electromagnet, two front and rear movable needle selection pieces and two springs are required, so that the structure is complicated, the number of parts is large, and the size is large and expensive. (B) Since two springs are used, and one of them must be stronger than the other spring but weaker than the magnetic force of the electromagnet, the setting of the force relationship is delicate and the accuracy is This causes defective needle selection. (C) Since the front-back sorting of the knitting needle butt as described above by the first and second needle selection pieces is effective only for sliding in one direction of the carriage, the needle selecting device having the above-mentioned structure is paired in right and left. That is, since the carriage must be provided on both the left and right sides and electrically controlled individually, it becomes expensive and the electrical control becomes complicated. Therefore, the present invention solves the above-mentioned conventional problems, and has a simple structure and a reliable needle selection operation, and a knitting needle butt can be selected forward and backward with respect to sliding of the carriage in both directions with one needle selecting device. An object is to provide a needle device.

A mountain-shaped cam that engages with the knitting needle butt is provided on the back surface of the carriage, and a sorting member that faces the top of the mountain-shaped cam and forms a sorting passage is movable back and forth between the front position and the rear position and at all times. It is installed by pressing forward with a spring to hold it in the front position. The knitting needle butt guided to the sorting passage by one oblique side of the chevron cam causes the sorting member to be pushed from the front position to the rear position against the spring, so that the knitting needle butt sorting passage is The front-rear width of the passing portion is made larger than the front-rear width of the selection passage when the selection member is at the front position. An electromagnet capable of holding the sorting member pushed to the rear position by the knitting needle butt at the rear position as it is by electromagnetic force is attached to the carriage. When the sorting member is held at the rear position by the electromagnet, the knitting needle bat pushed to the rear position moves laterally as it is, while when the sorting member is not held at the rear position by the electromagnet, the sorting member is moved to the rear position. When the pushed knitting needle butt crosses the top of the chevron cam, it is propelled forward by the spring. Left and right first distribution cams that engage with the knitting needle bats that have been sorted forward and backward by the sorting member and sort them back and forth on the right and left outer sides of the sorting passage on the back surface of the carriage, and the first sorting cams. The left and right second distribution cams that engage with the knitting needle bats distributed to the front and rear to further distribute these to the front distribution passage and the rear distribution passage are provided symmetrically. The left and right first distribution cams are vertically mounted on the carriage and are urged downward by springs. The left and right second distribution cams are attached to the carriage so as to be swingable back and forth. Further, the needle selection device according to the present invention may further have the following or configuration in addition to the above configurations. On the knitting needle butt, caps having distribution protrusions on the top surface are capped, and on the left and right end cams provided on both left and right ends of the carriage to distribute the knitting needle butt back and forth, on the distribution protrusions of the cap. A first cam portion that engages and a second cam portion that engages with the outer peripheral surface of the cap after the first cam portion and the distribution protrusion are engaged with each other are provided. A knitting method switching member that can be manually switched between a locked state in which the sorting member is restrained to the rear position against the spring and a lock released state in which the sorting member is released, and the knitting method switching member from the unlocked state.

部材の切換操作を軽快に行うことができる。The operation of the above constructions is as follows. The knitting needle butt is guided to the top portion by the hypotenuse of the chevron cam and pushes the sorting member to the rear position against the spring to enter the sorting passage between the top of the chevron cam and the sorting member. At this time, when the electromagnet is turned on, the selection member is held at the rear position by the electromagnetic force of the electromagnet, so that the knitting needle butt moves laterally without receiving the repulsive force (spring force) from the selection member, and the first vibration is generated. After being guided to the rear by the minute cam, it is further guided to the rear distribution path by the second distribution cam. On the other hand, when the electromagnet is off, the knitting needle butt that has entered the sorting passage continues to receive the repulsive force (spring force) from the sorting member,
On the contrary, from the time when the top of the mountain-shaped cam is exceeded, it is pushed back forward by this repulsive force, guided forward by the first distribution cam, and then guided further forward by the second distribution cam. . The front and rear sorting and sorting operation of such a knitting needle bat are
The same is done for either the left or right direction of the carriage. Since the left and right first distribution cams are vertically movable and are urged downward by springs, it is possible to buffer the impact when the knitting needle butt is engaged. Since the left and right second distribution cams can swing back and forth, respectively, when a traversing knitting needle butt collides, it tilts while being slightly pushed by the knitting needle butt, and is smooth without blocking the lateral movement of the knitting needle butt. Sort into. According to the above configuration, when the knitting needle butt introduced into the passage on the back of the carriage is sorted back and forth by the end cams on the left and right ends of the carriage, the distribution protrusion on the top surface of the cap attached to the knitting needle butt ends first. After engaging with the first cam portion of the cam and being slightly distributed, the outer peripheral surface of the cap is engaged with the second cam portion and is further biased in the distributed direction of the knitting needle butt. That is, it is possible to avoid the lateral movement of the knitting needle bat by the two-step distribution. According to the above configuration, when the sorting member is locked in the rear position by the knitting method switching member, the knitting needle butt is always sorted backward, so that the knitting needle butt is flat knitted, and when unlocked, the knitting needle butt follows the on / off of the electromagnet. As described above, the patterns are knitted in the front and back, resulting in pattern knitting. When the knitting method switching member is switched from the unlocked state to the locked state, the electromagnet is in a non-energized state, that is, is forcibly turned off, so that the sorting member can be released from the magnetic force of the electromagnet, and the knitting method switching member can be switched. Can be done lightly.

As shown in FIG. 2, the sorting cam 13 is fixed to the lower side of the front end of the vertical front and rear operation plate 23 of a magnetic material, and constitutes one sorting member 24 with this. As shown in FIG. 3 and FIG. 3, the front-rear operation plate 23 is slidable back and forth so as not to be disengaged in the guide groove 26 of the resin electromagnet mounting base plate 25 screwed onto the carriage base plate 2. It is fitted and urged forward by a spring 27. By this biasing, the sorting cam 13 is normally held at the front position shown by the chain line in FIG. Front and rear working plate
The rear end of 23 is projected downward from the window hole 28 provided in the carriage base plate 2, and the sorting cam 13 attached to the lower side of the tip is projected from the window hole 28 to the lower side of the carriage base plate 2. ,
It can be moved back and forth within the width of the window hole 28. Further, a locking projection 29 is provided on the upper side of the rear end of the front-rear operation plate 23. As shown in FIG. 3, a pair of left and right electromagnets 30 are fixed on the left and right sides of the front and rear operation plate 23 on the electromagnet mounting base plate 25. As shown in FIGS. 6 and 7, the left and right electromagnets 30 have their N and S magnetic pole faces 30N and 30S oriented in the same direction, and their N and S poles face each other. The front and rear actuating plates 23 are arranged symmetrically so as to sandwich the left and right sides. When the left and right electromagnets 30 are simultaneously energized, the front and rear actuation plates
23 is attracted and held despite the bias of the spring 27. As shown in FIG. 2 and FIGS. 6 and 7, a weaving method switching member 32 having a circular dial knob 32a is rotatably supported on a supporting shaft 31 integrally projecting on the carriage base plate 2. There is. On the lower side of the knitting method switching member 32, a sliding blade 33 having a guide elongated hole 33a fitted to the support shaft 31 is mounted so as to be slidable back and forth. The sliding vane 33 is provided with a pin 34 projecting upward and an engaging elongated hole 35 is provided in front of the pin 34. The locking projection 29 at the rear end of the front-rear operation plate 23 slidably projects into the engagement elongated hole 35. The knitting method switching member 32 is provided with a switching elongated hole 36 having an arc shape as a whole, and the pin 34 of the sliding vane 33 projects into the switching elongated hole 36. The switching elongated hole 36 includes a pattern knitting portion 36a that draws an arc having a large radius from the center of rotation (the support shaft 31) of the knitting method switching member 32, a flat knitting portion 36b that draws a small arc, and a bent portion 36c that connects these. Consists of. On the outer peripheral edge of the knitting method switching member 32, a switch actuating cam portion 37 is provided with a bent portion 36c of the switching elongated hole 36.
It is formed so as to project at a position facing to. The switch actuating cam portion 37 has a sufficient arc length that extends beyond both ends of the bent portion 36c. On the other hand, as shown in FIG. 3, a holding plate 38 mounted on the electromagnet mounting base plate 25 is provided with a switch member 39 which is actuated by a switch actuating cam portion 37 to shut off the left and right electromagnets 30 from the power source. . When the knitting method switching member 32 is set at the pattern knitting position shown in FIG. 6, the pin 34 of the sliding blade 33 engages with the pattern knitting portion 36a of the switching slot 36, and the sliding blade 33 Hold in the front position. In this case, since the sorting cam 13 can move back and forth with respect to the window hole 28 and the locking projection 29 of the forward / backward moving plate 23 with respect to the engaging elongated hole 35, the sorting cam 13 and the forward / backward operating plate 23 can move. Is allowed to move back and forth by the selection member 24, the switch actuating cam portion 37 of the knitting method switching member 32 is disengaged from the switch member 39, and the electromagnet 30 can be energized.
By controlling ON / OFF of, the needle for pattern knitting is selected as described later. However, when the knitting method switching member 32 is manually turned clockwise in FIG. 6, as shown in FIG. 7, the flat knitting portion 36 of the switching slot 26 is changed.
When the pin 34 is engaged with b, the sliding blade 33 is retracted, so that the sliding blade 33 is pulled by this and the sorting member 24 is also retracted against the spring 27, and is locked in the rear position so that it cannot move back and forth. At this time, the switch actuating cam portion 37 of the knitting method switching member 32 pushes the contact piece 39a of the switch member 39 to switch the switch member 39, so that the electromagnet 30 is disconnected from the power supply. The left and right first distribution cams 16 are substantially elliptical left and right guide holes provided in the electromagnet mounting base plate 25 as shown in FIG.
40 are fitted so that they can move up and down, but cannot rotate. In this distribution cam 16, since the flange portion 16a at the upper end is pressed from above by the pressing spring 41 having the base end fixed to the lower surface of the pressing plate 38, the flange portion 16a is normally pressed against the electromagnet mounting base plate 25. Is held at the lower limit position, and the left and right distribution cams are
The lower end portion of 16 projects downward from the window hole 28 of the carriage base plate 2 on both the left and right sides of the selection passage 15. The lower end edge of the distribution cam 16 is like a cutting edge that is pointed toward the tip of the distribution cam 17 of the base 2. That is, the front and rear surfaces of the lower end form front and rear slopes, and the lower end edge that is the ridgeline of these forms the sorting passage 15
It is a hypotenuse that slopes downward from the side toward the left and right. The knitting needle butt 21 that has passed through the sorting passage 15 is distributed to the front when the rear slope of the distribution protrusion 22 engages with the front slope of the first distribution cam 16, and the distribution protrusion is distributed. When the front slope of 22 engages with the rear slope of the first distribution cam 16,
It is distributed to the rear. When engaged in this way, the distribution cam 16 has a cushioning action because it has a margin to ascend against the pressing spring 41. The left and right second distribution cams 17 have a triangular shape as shown in FIG. 3, and the front surface and the rear surface thereof have the knitting needle butt 21 as shown in FIGS. The front and rear slopes are inclined in the opposite direction from the tip in order to distribute to the passage 43. The rear surface of the left and right guide cams 18 is the second distribution cam 17
The slope is larger than the slope on the rear side. The distribution cam 17 and the guide cam 18 are integrated as described above, and a shaft portion having a screw hole 44 on the upper surface of the distribution cam 17 is provided.
45 and a spring hooking pin 46 are integrally projected. Then, the shaft portion 45 of the left and right sorting cams 17 and the spring hooking pin 46 are
The carriage base plate 2 is inserted into the left and right bearing long holes 47 provided on the left and right respectively, and the screw 48 is inserted into the screw hole 44 from above the carriage base plate 2.
The left and right distribution cams 17 and the left and right guide cams 18 integrated with the left and right distribution cams 17 are pivotally attached to the lower side of the carriage base plate 2 so as to be able to swing back and forth with the shaft portion 45 as a fulcrum. Bearing long hole
The width of 47 is slightly larger than the outer diameter of the spring hooking pin 46, and the left and right distribution cams 17 and the left and right guide cams 18 are allowed to swing back and forth within a slight predetermined angle range. Left and right sorting cam 17
A tension spring 49 is stretched between the spring hooking pins 46, and the left and right distribution cams 17 are normally held in a state where the triangular tips thereof are directly opposed to each other. The end cams 10 at the left and right ends of the carriage base plate 2 are formed by forming two triangular first and second cam portions 10a and 10b with their tips facing outward as shown in FIGS. ing. First
The cam portion 10a of the second cam portion 10a is formed at a height that engages with the distribution protrusion portion 22 of the knitting needle butt 21, and the second cam portion 10b has a height that engages with the outer peripheral surface of the cap 20 and the first cam portion. It is formed slightly inside 10a. The end cams 19 at the left and right ends of the rear partition wall 6 are also the first and second
The two cam portions 19a, 19b are formed in the same manner as the end cam 10. In FIG. 1, reference numeral 50 is a yarn mouth, and in FIGS. 2 and 8, 51 is a resin needle bed. Also in FIG.
A, B, C, D indicate positions of the knitting needle butt 21 on the needle bed 51, A is a rear needle rest position, B is a rear knitting position, C is a front knitting position, and D is a front needle rest position. Next, the operation of this needle selection device will be described. FIG. 1 is a path of the knitting needle butt 21 when the selection member 24 is unlocked by the knitting method switching member 32 and, for example, intarsia knitting is performed, and FIG. 4 is an enlarged view of a part thereof. Knitting needle butt in rear knitting position B (or front knitting position C)
Reference numeral 21 denotes a guide cam which passes from the rear of the main cam 7 between the main cam 7 and the switching guide cam 8 as the carriage 1 slides.
It passes through between 18 and the front partition wall 4, and enters the front distribution passage 42 as shown in FIG. The knitting needle butt 21 entered here enters the selection passage 15 while being guided by the peripheral surface of the cap 20 slidingly contacting one oblique side 12b of the chevron cam 12. At this time, the selection cam 13 is at the front position shown by the chain line in the figure, and therefore the front-rear width of the selection passage 15 is smaller than the distance H between the outer peripheral surface of the cap 20 of the knitting needle butt 21 and the rear surface of the distribution protrusion 22. With its rear surface engaged with the front edge 13a of the selection cam 13, the selection cam 13 is pushed (retreated) from the front position shown by the chain line in the figure to the rear position shown by the solid line against the spring 27. . When the electromagnet 30 is off when retracted in this manner, the front-rear actuating plate 23 is not attracted to the electromagnet 30 and receives the bias of the spring 27 as it is, so that the knitting needle butt 21 exceeds the top 12a of the chevron cam 12. As shown by the chain line in the figure, the sorting cam 13 propels it in the opposite direction to the front, and the rear slope of the distribution protrusion 22 engages with the front slope of the first distribution cam 16. At this time, since the first distribution cam 16 can move up and down and is pressed downward by the pressing spring 41, the shock caused by the collision with the knitting needle butt 21 can be buffered. The knitting needle butt 21 is distributed to the front by the front slope of the first distribution cam 16, and the other oblique side 12c of the mountain-shaped cam 12 is further distributed by the propulsive force of the selection cam 13.
Is guided to the front distribution path 42 along the front side slope of the second distribution cam 17. On the other hand, when the left and right electromagnets 30 are simultaneously turned on when the sorting cam 13 is retracted to the rear position by the knitting needle butt 21, the front and rear working plates 23 are attracted from the left and right sides by the magnetic pole surfaces 30N and 30S of these electromagnets 30, As shown in FIG. 5, the sorting cam 13 is held at the rear position. Therefore, the knitting needle butt 21 moves laterally as it is from the top portion 12a of the chevron cam 12, the front slope of the distribution protrusion 22 engages with the rear slope of the first distribution cam 16,
After the knitting needle butt 21 is distributed rearward, the knitting needle butt 21 is distributed to the rear distribution passage 43 along the rear slope of the second distribution cam 17. In this case, since the second distribution cam 17 can swing slightly back and forth as described above, the cap 20 of the knitting needle butt 21
Even if the outer peripheral surface of the second distribution cam 17 collides with the tip of the second distribution cam 17, the distribution cam 17 escapes slightly forward, so that the knitting needle butt 21 can be smoothly traversed and distributed. The knitting needle butt 21 sorted by the sorting cam 17 is guided further rearward by the guide cam 18. In this way, when the knitting needle butt 21 enters the sorting passage 15, it is sorted back and forth one by one according to the on / off state of the electromagnet 30, and further sorted by the first and second sorting cams 16 and 17. The knitting needle butt 21 distributed to the front distribution passage 42 takes the front knitting position C when exiting the carriage 1 as shown in FIG. 1, and the knitting needle butt 21 distributed to the rear knitting passage 43 is rear knitting. Take position B. In the case of intarsia knitting, when the sliding direction of the carriage 1 is reversed, the knitting needle butt 21 at the front knitting position C is also guided by the switching cam 9 and merges with the knitting needle butt 21 at the rear knitting position B. Then, these knitting needle butt 21 enters the sorting passage 15 from the left and right opposite directions, and the electromagnet 30 is turned on / off in the same manner as described above.
According to the OFF state, it is sorted back and forth, and further sorted by the first and second sorting cams 16 and 17 forward and backward. In the case of plain knitting, the switching cam 9 is switched to the position shown by the chain double-dashed line in FIG. 1, and the knitting method switching member 32 is turned from the state shown in FIG. 6 to the state shown in FIG. In this case, if the electromagnet 30 is turned on in the same manner as when knitting or pulling up knitting, the front and rear working plate 23 is attracted to the electromagnet 30, and therefore the sorting by the front and rear working plate 23 and the sorting 13 cam is performed. In order to retract the member 24, in addition to the force against the spring 27, a force against the attracting force of the electromagnet 30 is also required, which is a large operation for turning the knitting method switching member 32 to the state shown in FIGS. 6 to 7. You need power. However, when the knitting method switching member 32 is rotated clockwise from the state shown in FIG. 6, the pin 34 of the sliding blade 33 is bent at the bent portion 36c of the switching slot 36.
Before entering, the switch actuating cam portion 37 actuates and switches the switch member 39 so that the electromagnet 30 is disconnected from the power source as described above. Therefore, when the sorting member 24 is actually retracted, the pin 34 is bent at the bent portion 36.
As the electromagnet 30 is forcibly turned off immediately before the process of entering the flat knitting portion 36b through c, the knitting method switching member 32 is moved from the pattern knitting position of FIG. 6 to the flat knitting position of FIG. The attraction force of the electromagnet 30 does not act when switching to the knitting position. When the knitting method switching member 32 is switched to the flat knitting position shown in FIG. 7, the selection cam 13 is locked in the rear position as described above. In this case, the knitting needle butt 21 at the front knitting position C enters the space between the opening / closing cam 11 and the end cam 10 as it is and moves laterally while being guided by the front partition wall 4, and the knitting needle butt 21 at the rear knitting position B moves at the switching cam. 9 Knitting needle butt from the front knitting position C
Merge with 21. And these knitting needle butt 21 is a Yamagata cam 12
Guided by the hypotenuse 12b of the car and enter the screening passage 15, the screening cam 1
Since 3 is locked in the rear position, as shown in FIG. 5, any knitting needle butt 21 laterally moves straight from the top 12a of the chevron cam 12 and is sorted rearward by the first sorting cam 16. , The second distribution cam 17 distributes further rearward, and when the switching cam 9 is pushed open through the rear distribution passage 43 to get out of the carriage 1, which knitting needle butt 21
Also takes the rear knitting position B. When the knitting needle butt 21 separated from the carriage 1 is sorted back and forth by the end cam 10, first, the slope of the distribution protrusion 22 of the knitting needle butt 21 is moved to the first end of the end cam 10 as shown in FIG. After being engaged with the inclined surface of the cam portion 10a and distributed slightly back and forth, the outer peripheral surface of the cap 20 is continuously moved to the second cam portion 10b.
It is further divided in the same direction by engaging with the slope of the. That is, since the knitting needle butt 21 is distributed in two stages, the straight collision with the end cam 10 does not hinder the traverse of the knitting needle butt 21, and the knitting needle butt 21 can be distributed smoothly. This also applies to the case where the end cam 19 is used.

の切換操作を軽快に行うことができる。The needle selecting device of the present invention has the following effects. Instead of positively moving the knitting needle butt or the needle selection piece by the electromagnetic force of the electromagnet to sort back and forth, the knitting needle butt causes the sorting member to retreat from the front position to the rear position, and the electromagnet is turned on and off during the retreat. When it is on, the knitting needle bat is laterally moved as it is while the sorting member is held at the rear position by its electromagnetic force, while when the electromagnet is off, the knitting needle bat is propelled forward by the spring force acting on the sorting member. In order to sort the knitting needle butt back and forth,
The structure is simple and the operation is reliable as compared with the conventional structure in which a pair of movable selection pieces and springs are required. After the knitting needle bats sorted front and back are sorted forward and backward by the first sorting cam, further sorted by the second sorting cam forward and backward, the knitting needle bats can be reliably guided to the sorting passages forward and backward. It is economical because one needle selecting device can similarly select the needle in either the left or right sliding direction of the carriage. Since the first distribution cam is vertically movable and is urged downward by the spring, it is possible to buffer the impact when the knitting needle butt is engaged. The second distribution cams on the left and right can swing back and forth, and when a laterally moving knitting needle butt collides, it tilts while being slightly pushed by the knitting needle butt, so that the knitting needle butt can be smoothly moved without blocking the lateral movement. You can sort. According to claim 2, when the knitting needle butt introduced into the passage on the back side of the carriage is sorted back and forth by the end cams at the left and right ends of the carriage, the distribution protrusion on the top surface of the cap attached to the knitting needle butt ends first. Since the outer peripheral surface of the cap is engaged with the second cam portion and is further biased in the direction in which the knitting needle bat is distributed after engaging with the first cam portion of the cam and being slightly distributed, the knitting needle butt It can be sorted smoothly without blocking the lateral movement of the car. According to the third aspect, the plain knitting mode and the pattern knitting mode are easily switched by manually operating the knitting method switching member to switch between the locked state in which the sorting member is locked at the rear position and the locked state in which the sorting member is released. be able to. When switching the knitting method switching member from the unlocked state to the locked state, the electromagnet can be forcibly turned off.
The sorting member can be released from the magnetic force of the electromagnet, and the switching operation of the knitting method switching member can be performed easily.
