[Industrial applications]
The present invention relates to a circular knitting machine that knits a pattern by electromagnetically controlling operations of a knitting tool, for example, a sinker, a knitting needle (latch needle, compound needle), an intermediate member (jack, etc.), a hook member, and the like. It relates to a card device.
[0002]
[Prior art]
Taking a pile patterning device using a sinker as an example, a conventional device is, for example, as described in Japanese Patent Application Laid-Open No. 3-45755 (see FIG. 11 attached). That is, a knitting needle N mounted on the needle groove of the rotary cylinder C and controlled by a cam member, and a sinker dial SD provided on the upper outer peripheral side of the rotary cylinder C, and a plurality of upper and lower pairs are provided in the cam groove of the sinker dial SD. The sinker S and the select jack SJ to be formed are slidably fitted so as to be pushed by the respective cam members in the horizontal direction. Each butt SJ1 is formed at the outer end of each select jack SJ, and each butt SJ1 of the select jack SJ is pushed by selectively pushing an actuator A provided corresponding to each bat. In addition, the sinker S engaged with the select jack SJ is pushed in the horizontal direction, and the knitting operation of the knitting needle N is performed to perform the pile pattern setting operation.
[0003]
Japanese Patent Application Laid-Open No. Hei 5-239751 discloses a circular knitting machine using a knitting tool controlled by a swinging piece.
[0004]
[Problem to be solved]
In the pile pattern setting device described in JP-A-3-45755, the butt at the outer end of the pile sinker is pushed by the operating piece of the actuator. Not only was the speed limited and high-speed operation was difficult, but also as can be seen from FIG. 11, the view of the knitted parts was obstructed by the holding members and actuators on the outer periphery of the knitted parts. It is difficult to check the knitting state of the section and to supply the knitting yarn to the knitting needle via the yarn path member when the knitting yarn is cut.
[0005]
Further, Japanese Patent Application Laid-Open No. Hei 5-239751 discloses that not only a knitting needle but also a sinker can be controlled using a rocking piece, but a specific embodiment of the sinker control is not disclosed. Regarding the control of the knitting needle, the swinging piece is provided with a plurality of protruding control bats. There is a risk that the rocking piece may break the bat. Furthermore, since the knitting cam that engages with the control butt has a vertical cross section, if any external force acts on the rocking piece, the control bat may come off the knitting cam.

It is preferable that the intermediate member lasing cam 9 be a mechanism that can be moved in and out. In FIG. 12, by turning the knob 9c, the intermediate member lasing cam 9 can be drawn in by the screw 9b fixed to the knob screwing with the sinker cap. When the intermediate member lasing cam 9 comes out as shown in FIG. 6, only the non-pile selection is performed, and it can be used, for example, when adjusting the degree. Further, since the intermediate member lasing cam 9 is supported by the spring 9a, when an abnormal external force is applied to the intermediate member lasing cam 9, the intermediate member lasing cam 9 retracts, and damage to the butt 3a of the intermediate member 3 is minimized. It can be.
[0016]
As shown most clearly in FIGS. 1 and 10, a rocking piece base material 4 is set in the sinker groove in the outer peripheral direction of the intermediate member 3, and the rocking piece base material 4 The swinging piece 5 is fitted as much as possible. The rocking piece base material 4 has at least one butt 4a controlled by a cam track T4 formed by the first intermediate cam 10 and the second intermediate cam 11. The upper part of the rocking piece base material 4 is a semicircular recess 4e. A circular projection 5e protrudes from the lower part of the swinging piece 5 so as to correspond to the recess 4e, and the recess 4e and the projection 5e are pivotally connected to each other. The left and right ends of the swinging piece 5 are symmetrical left and right, forming upper wedge portions 5c and 5d and lower portions to be sucked 5a and 5b. A step is provided between the left and right sucked portions 5a and 5b and the lower center portion.
[0017]
Suction members 13 a and 13 b (see FIGS. 1 and 3) are attached to the sinker cap 17 so as to face the rocking piece 5. These suction members 13a and 13b selectively suction the suctioned portions 5a and 5b of the oscillating piece 5 based on a signal output from the controller based on predetermined pattern information set in advance. Before the rocking piece 5 enters the suction members 13a and 13b, the rocking piece 5 in a free swing state is horizontally moved by the inclined surface of the rocking piece cancel cam 14 (see FIGS. 1 and 10). It is desirable that the swinging pieces 5 pass through the suction members 13a and 13b. Further, it is preferable to use a control electromagnet as the attraction members 13a and 13b.
[0018]
When the sinker 2 is moved forward, a signal is sent from the controller to the suction member 13b, and the suctioned portion 5b of the swinging piece 5 corresponding to the suction member 13b is sucked (see FIG. 3 <BB cross section in FIG. 1>). ). By this time, the ground yarn GY has been supplied to the knitting needle 1 from the ground yarn supply port 6a over the sinker top 2f of the sinker 2.
[0019]
After the sucked portion 5b passes through the suction member 13b, the wedge portion 5d of the rocking piece 5 engages with the upwardly inclined portion 12a of the trapezoidal cross section of the rocking piece lasing cam 12, and the rocking piece 5 becomes a rocking piece mother. It is extruded in the direction of the center of the knitting machine together with the material 4 (see FIG. 4a <C-C cross section of FIG. 1).
[0020]
The front end 4 b of the extruded rocking piece base material 4 pushes the rear end 3 b of the intermediate member 3. The butt 3a of the intermediate member 3 is engaged with the upwardly inclined portion 9a of the intermediate member lasing cam 9, and the intermediate member 3 is pushed out toward the center of the knitting machine (see FIG. 5a <cross-sectional view taken along line DD in FIG. 1).
[0021]
The rear end 2c of the sinker 2 is extruded by the front end 3c of the extruded intermediate member 3. When the intermediate member 3 reaches the vertex 9b of the intermediate member lasing cam 9, the extruded intermediate member 3 advances the sinker 2 to a position where the pile loop can be formed on the sinker nose 2b (FIG. 6A <E in FIG. 1). -E sectional view>). At this time, the pile yarn PY is supplied to the knitting needle 1 from the pile yarn supply port 6b over the sinker nose 2b of the sinker 2. FIG. 7 shows a state in which the pile loop PL is knitted on the sinker nose 2b by the sinker 2 that has moved forward.
[0022]
At the vertex 9b of the intermediate member lasing cam 9, it is preferable that the extruded tip of the nose 2b of the sinker 2 is set to move 0.3 mm or more inward from the circumferential operation line of the knitting needle. By setting in this way, a pile loop can be reliably formed at a position 0.3 mm or more away from the tip of the sinker nose 2b.
[0023]
After the intermediate member 3 is pushed out to the position where the intermediate member 3 engages with the intermediate member lasing cam 9 by the rocking piece preform 4, the butt 4 a of the rocking piece preform 4 engages with the downward inclined portion 10 b of the first intermediate cam 10. Then, the rocking piece base material 4 is returned to the non-pile position together with the rocking piece 5.
[0024]
In the above configuration, the intermediate member 3 and the intermediate member control cam may be omitted. In this case, the rocking piece lasing cam 12 pushes the rocking piece 5 together with the rocking piece base material 4, and the rocking piece base material 4 directly pushes the sinker 2.
[0025]
When the sinker 2 is not moved forward, a signal is sent from the controller to the suction member 13a to suck the suctioned portion 5a of the swinging piece 5 corresponding to the suction member 13a (see FIG. 3). In FIG. 3, it is not clear which of the suctioned members 5a and 5b is adsorbed to which of the adsorption members 13a and 13b due to a drawing limitation.
[0026]
The swinging piece 5 sucked by the suction member 13a does not engage with the rising slope 12a of the swinging piece lasing cam 12, and the swinging piece 5 passes below the rising slope 12a of the swinging piece lasing cam. Then, the rocking piece 5, the rocking piece base material 4, and the intermediate member 3 move in the circumferential direction without moving in the front-rear direction (see FIGS. 4B, 5B, and 6B). The sinker 2 is controlled only by the sinker cams 7 and 8 without engaging with the intermediate member 3. At this time, even if the pile yarn PY is supplied, the pile loop PL is not formed because it is knitted on the sinker top 2f. The ground yarn GY is supplied to the knitting needle 1 over the sinker top 2f of the sinker 2 together with the pile yarn PY (see FIG. 6B <cross-sectional view taken along the line EE of FIG. 1).

The suction members 133a and 133b are attached to the needle selecting device 36 so as to face the rocking piece 51. These suction members 133a and 133b selectively suction the suctioned portions 51a and 51b of the oscillating piece 51 based on a signal output from the controller based on predetermined pattern information set in advance. Before the rocking piece 51 enters the suction members 133a and 133b, the rocking piece 51 in a free swing state is aligned horizontally by the inclined surface of the rocking piece canceling cam 141 (see FIG. 13). It is desirable that the swinging piece 51 passes through the suction members 133a and 133b. Further, it is preferable to use a control electromagnet as the attraction members 133a and 133b.
[0042]
When the knitting needle 1 is not raised, a signal is sent from the controller to the suction member 133b, and the suctioned portion 51b of the swinging piece 51 corresponding to the suction member 133b is sucked. After the sucked portion 51b passes through the suction member 133b, the wedge portion 51d of the rocking piece 51 engages with the upwardly inclined portion 120a of the trapezoidal cross section of the rocking piece lasing cam 120, and the rocking piece 51 becomes a rocking piece mother. It moves upward with the material 41. Then, the butt 41b that engages with and disengages from the cancel cam 102 immediately below the U-shaped portion 41f of the swinging piece base material 41 is pushed toward the center by the inclined surface 102a of the cancel cam 102.
