Description

[Detailed description of the invention] This invention relates to a set-up comb for a flat knitting machine.

For example, as shown in FIG. 1, a set-up comb 6 having hook-shaped comb teeth 4 at the tips of the teeth is provided below the opening 3 of the V-bed flat knitting machine 1 so that the set-up comb 6 can be moved up and down. The tooth tip 4a of the needle bed 2 is configured to be able to move upwardly and retractably from the opening 3, and the set-up comb 6 is connected to an elevating drive device such as a chain 7, and is moved upwardly and downwardly toward the lower side of the needle bed 2. Set-up comb 6
a backward position that does not interfere with the operation of the set-up comb 6; and a forward position that allows the knitted fabric (not shown) attached to the set-up comb 6 in the lowered position to be pressed from behind the hook of the comb teeth 4 of the set-up comb 6. A stitch separation action plate 8, in which the stitch separation action section 8a can freely move forward and backward, is disposed between the stitch separation action plate 8 and the forward and backward drive device 9 thereof, which is connected to the forward position ( With respect to the stitch separation action portion 8a of the stitch separation action plate 8 (dotted line in Fig. 1),
A drive device (not shown) capable of relatively upwardly displacing the position of the tooth tip 4a of the set-up comb 6 by a certain amount is disposed at least on either the set-up comb 6 or the stitch separation action plate 8. When the set-up comb 6 is placed, the tip of the teeth 4a
When the set-up comb 6 is raised to above the opening 3, the hook at its tip can catch the stitches of the set-up course within them.If the set-up comb 6 is set free in this state, even with the weight of the set-up comb 6, This allows the knitting start end of the knitted fabric 25 to be pulled down while applying appropriate tension to the knitted fabric, and when the set-up comb 6 has descended to a predetermined position (the position indicated by the chain line in Figure 1),
Pushing the vicinity of the lower end of the knitted fabric 25 from the back side of the hook of the comb teeth 4 with the stitch separation action plate 8 and slightly raising the set-up comb 6 or slightly lowering the stitch separation action plate 8 allows the knitting to begin. The stitches can be automatically removed from the hooks of the comb teeth 4.

More specifically, this invention is intended to provide a set-up comb that can be conveniently implemented in a set-up device as described above.

That is, generally the width of a knitted fabric knitted by a flat knitting machine can be changed arbitrarily. Therefore, the set-up comb 6 as described above has the following effects over the entire width of the needle bed:
It must have 4 comb teeth. However,
If all of the comb teeth 4 are fixed at the same height with respect to the substrate 5, when a knitted fabric of an arbitrary width narrower than the total width is knitted by this flat knitting machine,
The comb teeth 4 that are not covered with knitted fabric are the comb teeth 4 that are covered with knitted fabric.
Because it is at the same height as the comb teeth 4, if the leftover yarn on the knitting start side gets entangled with the former comb teeth 4, the loop of the knitted fabric end hanging on the comb teeth 4 should be Even if it can be automatically removed by the stitch separation action plate 8, the above-mentioned leftover yarn entangled with the comb teeth 4 where the loop has not been formed will be removed by the stitch separation action plate 8.
It has been found that there are cases where this cannot be avoided.

This invention is based on the above-mentioned knowledge and attempts to provide a set-up comb that does not cause the above-mentioned troubles. The set-up comb has a large number of comb teeth embedded in the upper end of a substrate, and the substrate has a large number of longitudinal protrusions arranged in parallel on the front surface of the upper part, and the protrusions are Two straps with appropriate vertical spacing are placed horizontally on the front part, and the space between each of the protrusions has a large number of comb teeth like the needle grooves of the needle bed of a flat knitting machine. Each of the comb tooth grooves has a tooth tip as described above at its upper end, and a flexible tooth rod portion that can be elastically deformed back and forth within the comb tooth groove is provided at the lower part thereof. , and a comb tooth having a butt is implanted in the front surface of the flexible tooth rod portion so that it can be inserted and removed; In a normal state, the flexible tooth rod portion has a butt in the comb tooth groove. It has a shape that can be engaged with each band, and when the butt is positioned between the upper and lower bands, the comb teeth are maintained in a position where the tips of the teeth protrude a predetermined amount from the upper end of the comb tooth groove. , when the flexible tooth rod portion is elastically deformed, the comb teeth can freely slide up and down within the comb tooth groove without engaging the butt with the strap, and the lower end of each comb tooth and the lower part of the base plate Between the right places,
A spring for biasing the comb teeth in the downward direction is detachably provided, and the comb teeth are prevented from descending at a position where the tips of the comb teeth are drawn into the comb grooves. The set-up comb is characterized by the fact that it is equipped with a stopper.

One embodiment will be described with reference to FIG. 2 and below. In the set-up comb 6 of this invention, the comb teeth 4 and the substrate 5 for attaching the comb teeth 4 are particularly constructed as follows.

That is, on the front surface of the upper part of the substrate 5 (the left side surface in FIGS. 3 and 4), a large number of vertical protrusions 11 are arranged in parallel, and dovetail grooves are formed in the protrusions 11. Then, the two straps 1 in the transverse direction of the protrusion 11
2 and 13 are inserted horizontally with a certain vertical interval between them, and a large number of comb tooth grooves 14 shaped like the needle grooves of the needle bed of a flat knitting machine are inserted between each of the protrusions 11. The spacing portions are also formed. A flat comb tooth 4 is inserted into each comb tooth groove 14 behind the bands 12 and 13 from above so that it can be freely inserted into and removed from the comb tooth groove 14. The comb teeth 4 are provided with a hook-shaped tooth tip 4a as described above at the upper end facing forward, and at the lower part thereof, the tip is U-shaped when viewed from the side, and the tip portion is elastic back and forth within the comb tooth groove 14. It includes a displaceable flexible tooth rod portion 4b,
The front surface of the distal end of the flexible toothed rod portion 4b is provided with the band 1 by elastic deformation of the flexible toothed rod portion 4b.
2 and 13 are provided with protruding butts 16 that can be freely engaged and detached. That is, the flexible toothed rod portion 4b has a shape that allows the butt 16 to engage with the straps 12 and 13 in the normal state, and when the butt 16 is positioned between the two straps 12 and 13. , the comb teeth 4 are maintained in a state in which the tips 4a thereof protrude by a predetermined amount from the upper end of the comb tooth groove 14 (FIG. 3), and the band 1 is
Even with the vertical interval between 2 and 13, the comb teeth 4 can be moved up and down only within the range of a certain permissible stroke l, but the comb teeth 4 are Push the tip from the front,
When the flexible toothed rod portion 4b is elastically deformed, the butt 16 can be disengaged from the engagement with the bands 12 and 13, and the comb teeth 4 can be removed upwardly from within the comb tooth groove 14. 4 and lowered within the comb tooth groove 14 so that the tip 4a of the tooth is retracted into the comb tooth groove 14 (FIG. 4). 17 is for preventing the comb teeth 4 from descending at the position where the tip of the comb teeth 4 is drawn into the comb tooth groove 14.
This is a stopper consisting of a protruding strip that protrudes at a suitable place on the front surface of the lower part of the board 5, and reference numeral 18 denotes a spring hook formed at the lower end of the comb teeth 4 in order to bias the comb teeth 4 to the lowered position. 4c and a spring hanging protrusion 20 formed at the lower end of the plate 19 which is fixed at a proper position on the lower part of the board 5, is a spring detachably stretched.

In FIG. 2, 21 is a sleeve fixed to both sides of the base plate 5 of the set-up comb 6, and the set-up comb 6 is attached to a pair of vertical rails 22 into which the sleeve 21 can be slidably inserted. It is supported in an upright position and is movable up and down.

Since the set-up comb 6 according to this invention has the above-mentioned configuration, the comb teeth 4 of this set-up comb 6
pushes the upper end of the flexible toothed rod portion 4b from the front to elastically deform it, and pushes the butt 16 at the tip of the flexible toothed rod portion 4b into the comb tooth groove 1 deeper than the strap 12.
4, it can be inserted into the comb tooth groove 14 from above, and the protrusion 16 is inserted into the upper and lower straps 1.
When the spring 18 is stretched between the hook 4c at the lower end of the comb teeth 4 and the hook 20 on the substrate 5, the comb teeth 4 will be attached to the flexible tooth rod portion 4b. The butt 16 of the butt 16 is engaged with the ferrule 13, and the tooth tips 4a of the butt 16 are held in the operating position in which they protrude by a predetermined amount from the upper end of the base plate 5 (Fig. 3), and in this state, the flexible toothed rod portion 4b When the front surface of the butt 16 is pushed deeper into the comb groove 14 than the strap 13, the comb teeth 4 are lowered by the force of the spring 18,
The tooth tip 4a is kept in a non-active position recessed into the comb tooth groove 14 (FIG. 4).

To return from this state to the state shown in Figure 3,
While pressing butt 16 from the front, insert comb teeth 4 into spring 1.
All you have to do is push it up against the force of 8.

As described above, the set-up comb 6 of this invention allows any comb tooth 4 to be moved up and down within the comb tooth groove 14, and can be extremely easily set to either the working position or the non-working position as described above. However, as shown in FIG. 2, if only the comb teeth 4 necessary for the set-up of the knitted fabric 25 are kept in the working position according to the set-up width of the knitted fabric 25, the set-up comb 6 can be Since all the comb teeth that have never existed at the knitting start end of the knitted fabric 25 are kept within the comb tooth groove 14 that cannot act on the knitting yarn 26 of the set-up course, the knitted fabric of any width Even in such cases, the knitted fabric can be smoothly separated from the set-up comb by using the above-mentioned stitch separation action plate without causing the troubles mentioned at the beginning.

In addition, in the set-up comb of this invention, the comb teeth 4 with the tooth tips 4a kept in the working position transfer the downward force applied by the spring 18 to the butt 16 held on the strap 13. However, each comb tooth 4 can be raised and lowered individually within the range allowed by the spacing between the upper and lower straps 12 and 13. It is freely displaceable and is always elastically biased in the direction of pulling down the knitted fabric. Therefore, in the set-up comb of this invention, when the pull-down resistance of the knitted fabric is not constant in the width direction due to forming knitting, etc., the comb teeth 4 automatically adjust to the resistance. By moving up and down, the optimum pulling force can be applied to the entire width.

Furthermore, in the set-up comb of this invention, the comb teeth 4 can be easily inserted and removed from the comb tooth grooves 14, so if the tips 4a of the comb teeth 4 are damaged, they can be easily replaced.

In the above embodiment, the flexible tooth rod portion 4b of the comb teeth 4 is formed into a U-shape, and a butt 1 is provided at the tip of the flexible tooth rod portion 4b.
However, the shape of this part of the comb teeth and the position of the butt are not limited to the above embodiment, and in other embodiments, for example, the comb teeth are 4 may be formed to have the side surface shape shown in FIG. 5 to form a flexible toothed rod portion 4b in which the butt 16 can be freely engaged and detached from the bands 12 and 13 in the same manner as described above.
