Description

[Detailed Description of the Invention] The present invention relates to an improvement of a device for switching the vertical arrangement position of a rubber machine needle bed for a hand knitting machine.

Conventionally, long holes in the vertical direction were provided in a pair of support plates hanging down from both left and right sides of the front side of the rubber machine needle bed, while vertical holes were provided in the long holes in the support plates on both left and right sides of the rubber machine needle bed. By providing movably fitted protrusions and selectively locking the left and right protrusions in at least two predetermined upper and lower positions within the elongated hole, the rubber machine needle bed can be adjusted in relation to the main machine needle bed. A rubber machine needle bed that can be placed at an upper knitting position involved in knitting and a lower knitting position slightly below the upper knitting position and also involved in knitting in relation to the machine needle bed. As the vertical arrangement position switching device, there are those shown in Japanese Utility Model Publication No. 53-46368 and the device shown in Japanese Utility Model Application Publication No. 53-1855.

According to the former known example, when the rubber machine needle bed is placed in the upper knitting position, the protrusion is engaged with a switching adjustment member, and when the rubber machine needle bed is placed in the lower knitting position, the protrusion is locked. According to the latter known example, when the rubber machine needle bed is placed in the upper knitting position, the protrusion is adjusted. When the needle bed of the rubber machine is placed in the lower knitting position, it is engaged with a switching adjustment member that is a separate member from the adjustment member.

Therefore, according to these known examples, both
When the rubber machine needle bed is placed in the upper and lower knitting positions, the protrusions are locked by the switching adjustment member and the adjustment body, which are separate members, so that the adjustment with the switching adjustment member is easy. The locking height of the protrusion is likely to be distorted due to dimensional errors in assembly with the parts, relative looseness due to long-term use, etc. There is a drawback that it cannot be placed accurately in the position, and in order to avoid this drawback, more precision than necessary is required in the relative arrangement and shape of the switching adjustment member and the adjustment member body, and the design and manufacturing thereof are difficult. The disadvantage is that the cost is high.

However, the present invention particularly includes a manual switching member which is supported movably between two positions on each of the left and right supporting plates, and which engages a protrusion in order to place the rubber machine needle bed in the upper knitting position in one of the moving positions. a first locking portion that locks the rubber machine needle bed in the other moving position, and a second locking portion that locks the protrusion to place the rubber machine needle bed in the lower knitting position; The needle bed of the rubber machine can be switched between the upper and lower knitting positions using only the switching member, thereby eliminating the drawbacks of the conventional method, and making it easy to simply move the manual switching member between the two positions. The rubber machine needle bed can be quickly and reliably switched from one of the upper and lower knitting positions to the other or vice versa by a simple operation.

Furthermore, a main machine carriage 47 and a rubber machine carriage 48 are mounted on the main machine needle bed 1 and the rubber machine needle bed 11, respectively, and are connected to each other so as to be integrally slidable by connecting fittings.

This embodiment is configured as described above.

The operation of the device for switching the vertical position of the rubber machine needle bed 11 will be explained below.

That is, first, the upper horizontal portion 22 of the support plate 21 is
is inserted between the upper lower surface of the mounting member 6 and the support rod 9, its fitting hole 23 is engaged with the protrusion 10 and suspended from the support rod 9, and the positioning piece 27 is inserted into the positioning plate 45. By engaging and attaching the rubber machine needle bed 11 to the main machine needle bed 1 and fixing the receiving piece 46 with the mounting bracket 2, the rubber machine needle bed 11 is fixed as shown in FIGS. 1 and 2. Place it in the upper formation position so that the

In order to move the rubber machine needle bed 11 from the upper knitting position to the lower knitting position, as shown in FIG.
It is rotated clockwise against the spring force of the spring 44 until it comes into contact with the stopper piece 36. Then, the small diameter portion 20 of the protrusion 16 engages with the second locking portion 42 from the first locking portion 41 via the inclined surface 43, and therefore, the rubber machine needle bed 11 is lowered to the lower knitting position.
In this state, the weight of the rubber machine needle bed 11, which is much larger than the elasticity of the spring 44, is applied to the manual switching member 38 via the protrusion 16, so that the manual switching member 38 is moved to the position shown in FIG. It remains in position.

Conversely, in order to move the rubber machine needle bed 11 from the lower knitting position to the upper knitting position, the left and right manual switching members 38 are moved from FIG. 4 to FIG. 2 against the weight of the rubber machine needle bed 11. The rubber machine needle bed 11 can be returned to the upper knitting position by simply rotating it clockwise to the state shown.

Next, in order to place the rubber machine needle bed 11 from the above-mentioned upper knitting position or lower knitting position to an intermediate rest position or an unfinished rest position which is not involved in knitting in relation to the main machine needle bed 1, the manual switching member 38 is used. As shown in FIG. 5, the small diameter portion 20 of the protrusion 16 is rotated counterclockwise using the operating portion 39 against the spring force of the coil spring 37, as shown in FIG. 41, descends and once engages with the guide edge 30 (see Fig. 5), then descends further and engages with the intermediate holding edge 31 (see Fig. 6), whereby the rubber machine needle bed 1
1 is held in an intermediate rest position.

By further rotating the manual switching member 38 in the counterclockwise direction, the small diameter portion 20 of the protrusion 16 is
is disengaged from the intermediate retaining edge 31 and descends to engage the lower end retaining edge 32, thereby allowing the rubber machine needle bed 11 to be placed in the lower end rest position.

Furthermore, in order to place the rubber machine needle bed 11, which has been placed at the intermediate rest position or the lower end rest position, as described above, into the upper knitting position, the left and right sides of the rubber machine needle bed 11 must be kept in a substantially horizontal state by manual operation. It is sufficient to simply push up the small diameter portion 20 of the protrusion 16 into the curved groove 3.
By engaging with the inclined edge 33A of 3, the adjusting plate 2
9 in the counterclockwise direction in FIG. By rotating it counterclockwise, the small diameter portion 20 engages with the first locking portion 41 of the manual switching member 38, and the rubber machine needle bed 11 can be placed in the upper knitting position. be.

As described in detail above, the present invention has a manual switching member supported movably between two positions on each of the left and right support plates. A first locking part and a second locking part are provided for locking the protrusion in order to arrange it in a certain position. Therefore, by locking the protrusion with the first locking portion or the second locking portion of the manual switching member, the rubber machine needle bed can be moved up or down.
Since it has a configuration that can be switched to each of the lower knitting positions, the rubber machine needle bed can be placed in each of the upper and lower knitting positions by locking the protrusions with separate members, as in the conventional system mentioned at the beginning. It is possible to reliably avoid this configuration and the various drawbacks that arise from that configuration. Further, the rubber machine needle bed can be quickly and reliably switched from one of the upper and lower knitting positions to the other, or vice versa, by simply moving only the manual switching member between two positions. be.
