Description

[Detailed description of the invention]

[Industrial Field of Application 1] The present invention relates to a flat knitting machine, a needle bed and needles used therein. [Prior Art] In a conventional flat knitting machine, as shown in FIGS. 3 and 4, a plurality of needles 422 are arranged in parallel on a needle bed 21, and the needles 23 are inserted into the needle grooves. A knitting machine is known in which a cam 25 on a carriage is brought into contact with a butt 24 provided protruding from the needle 23 to cause the needle 23 to appear and disappear. Since knitting is performed by raising the needles 23 to the working position where they contact the cam 25 on the carriage, the m-dolles 23, which are not related to knitting, are lowered to the non-working position and are not used for knitting. The needle 23 used must be in the active position and must not fall into the inactive position. For this purpose, conventionally, an auxiliary needle 27 having an inverted U-shape is inserted into the needle 1122 with the lower side of the auxiliary needle 27 holding the end of the needle bed substrate 26, and the other side is brought into contact with the back surface of the substrate 26. It was slidably attached to the needle bed base plate 26 in contact with the needle bed base plate 26. When the needle 23 is placed in the operating position, the auxiliary needle 27 is pushed in, and the arm end 28 that contacts the back surface of the needle bed base plate 26 is engaged with the recess 29. When the needle 23 is placed in the inactive position, the butt 30 of the auxiliary needle 27
Pull it out until it touches 1. This causes needle 2
The bat 2A of No. 3 takes a non-active position where it does not come into contact with the cam 25. With the above structure, it is necessary to provide an auxiliary needle at the lower end of the needle bed 21 to ensure the working and non-working positions of the needle, and the operating range of the needle is also required, so the length of the needle bed is increased. However, it was also necessary to create a space for the auxiliary needle to operate.

Problem to be Solved by the Invention 1 In view of the above points, the present invention provides a knitting machine, a needle bed, and needles that can eliminate the use of auxiliary needles and shorten the length of the needle bed in the vertical direction. The purpose is to obtain. [Means for Solving the Problems] The knitting machine of the present invention communicates a plurality of needle grooves provided in parallel on a needle bed, and provides a needle locking wire at the lower part of the needle groove, so that the wire is inserted into the needle groove. On the side edge of the tail of the needle,
An engaging concave portion that engages with the needle locking wire was provided. The needle bed of the present invention has a plurality of needle grooves arranged in parallel at the bottom thereof.
A needle engagement wire was inserted across the plurality of needle grooves. The needle for a knitting machine of the present invention has a concave portion on the side edge of the tail portion for retaining a needle locking wire provided in the needle groove of the needle bed. K action] When the needle is passed through the needle grooves arranged in parallel on the needle bed and raised to a position where the tail end of the needle touches at least the needle locking wire provided to intersect with the needle grooves, the needle will be in the working position. When the needle is further pulled down and the engagement recess provided on the round end edge of the needle is engaged with the wire, the needle can take the inactive position 1. Then, due to the engagement between the wire and the engagement recess,
The needle is fixed without any movement. The above selection of needle positions is performed manually one by one. EXAMPLE An example of implementing the present invention will be described below with reference to the drawings. The needle bed 1 has a plurality of needles W43 arranged in parallel on the substrate 2. A wire 5 is provided in the lower part 4 of II3 to pass through the parallel needle grooves 3 and intersect with the needle grooves 3. On the other hand, an engagement recess 9 is formed in a portion of the end edge 8 of the needle 6 to be inserted into the needle groove 3 that contacts the innermost portion 7 of the needle 21i3 and is positioned at the needle tail. The edge 8 from the engagement recess 9 to the end of the needle tail is slightly retracted away from the innermost part 7 of the needle groove, and a wire abutment slope 10 is formed at the end of the needle, as will be described later. This can be easily done when the needle 6 is pulled down. In 11, is needle 6 the needle? A band 12 is a cam provided on the carriage 13 to prevent it from falling off from II3. When knitting is carried out in the above-mentioned knitting machine, the unused needles are manually pulled down to the inactive position I in advance. That is, by pressing the needle butt 15 with your fingers and applying force in the pulling direction, the actual wire is moved to the needle 6. The contact slope 10 crosses over the wire 5 and the engagement recess 9 engages with the wire 5, and the needle 6 is fixed without any movement and remains at that position during the knitting operation. (Figure 2). Conversely, when the needle 6 is placed in the operating position, the engagement recess 9 of the needle 6 and the wire 5 are disengaged by manually pulling up the butt 15 in one direction.
At least the wire abutting slope 10 is located above the wire 5 (this becomes the operating position). [Effects of the Invention] The tIl, needle bed, and needle of the present invention are constructed as described above. Therefore, the position of the needle is fixed by the wire in the needle groove, and the auxiliary needle can be removed because it can be selected between the working position and the non-working position without using the auxiliary needle as in conventional devices. Therefore, the length of the needle bed in the downward direction can be reduced accordingly, and its structure can also be simplified.
