JPH08325899A - Preparatory apparatus for looming in loom - Google Patents

Abstract

PURPOSE: To improve the operating efficiency of operations requiring relative movement of a warp yarn and a dropper pin without causing damage to the warp yarn or structural complication in a preparatory apparatus for looming of the type for supporting the warp yarn from a full warper beam in a state thereof previously threaded through the dropper pin, a heald and a reed. CONSTITUTION: This preparatory apparatus for looming is obtained by temporarily supporting a contact bar 3 and dividing rods 5 on a carrier pedestal so as to provide a larger interval (L0) between the top of the contact bar 3 and the tops of the dividing rods 5 than that (L1) between the top of a contact bar inserting hole 11 of a dropper pin 1 and a warp yarn inserting hole 12. Thereby, the warp yarn inserting hole of the dropper pin is maintained at a higher level than that of the tops of the dividing rods. The relation is further kept even when the warp yarn is slackened. As a result, the frictional resistance between the warp yarn and the dropper pin is not increased without bending the warp yarn. That is, the relative movement of the warp yarn and the dropper pin is facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine preparation device, and more particularly to a machine preparation device of a type in which warps from a full warp beam are preliminarily inserted through a dropper pin, a heald and a reed. The present invention relates to improvement of workability in the device.

[0002]

2. Description of the Related Art In machine work, it is common practice to insert warps from a full warp beam through dropper pins, healds and reeds in advance. After such insertion is completed, the full warp beam, the warp unit (comprising a dropper pin, a contact bar and a divide rod), the heald and the reed are supported by a supporting member such as a stand and a hanging member. In this way, when the circumference of the warp stop unit is supported by the support member, the warp stop unit is supported in the same state as when the loom was mounted.

In such a supporting state, as shown in FIG. 14, the distance L0 from the upper end of the contact bar 3 to the upper end of the divide rod 5 is from the upper end of the contact bar insertion hole 11 formed in the dropper pin 1. Warp insertion hole 12
The contact bar 3 and the divide rod 5 are supported so as to be smaller than the distance L1 up to. In other words, the dropper pin 1 is in a state of hanging on the warp.

However, in such a setting state, when the warp yarn is loosened, the dropper pin 1 is lowered by that amount, and the position of the warp yarn insertion hole 12 of the dropper pin 1 is lower than that of the divide rod 5. As a result, the warp is bent at the divide rod 5 and the warp insertion hole 12 of the dropper pin 1, and this bending increases the frictional resistance of the warp T to the dropper pin 1. Then warp T and dropper pin 1
It becomes difficult to move the and relative to each other (especially in the case of the fluff yarn or the wool yarn, this tendency becomes strong), and the work that requires such relative movement becomes complicated. That is, workability is reduced.

In order to avoid such inconvenience of workability deterioration,
In the technique proposed in Japanese Patent Application Laid-Open No. 2-264039, a vibration imparting mechanism that gives a relative vibration action between the dropper pin and the warp is used.

[0006]

However, according to such a conventional technique, since the warp is vibrated, the warp is easily damaged. In addition, since the vibration applying mechanism is provided, the structure of the stand is inevitably complicated.

In view of the above-mentioned drawbacks of the prior art, the present invention relates to a warp yarn preparation device of a type for supporting a warp yarn from a full warp beam in a state in which the warp yarn is inserted into a dropper pin, a heald, and a reed in advance. It is an object of the present invention to improve workability of a work that requires relative movement of a warp yarn and a dropper pin without causing structural complication.

[0008]

For this reason, in the present invention, the distance between the upper end of the contact bar and the upper end of the divide rod is greater than the distance between the upper end of the contact bar insertion hole of the dropper pin and the warp insertion hole. Therefore, the gist of the present invention is to temporarily support the contact bar and the divide rod on the stand so that

[0009]

The dropper pin is supported by the contact bar through the upper end of the contact bar insertion hole. Therefore, the upper end of the divide rod is maintained at the same height as or lower than the warp thread insertion hole of the dropper pin. Moreover, this relationship is maintained even if the warp yarn is loosened. Therefore, the warp does not bend, and the frictional resistance between the warp and the dropper pin does not increase. That is, the relative movement of the warp and the dropper pin becomes easy.

[0010]

EXAMPLE In the present invention, the relationship between the two distances (L0: L1) is defined as described above. Here, the "contact bar" is inserted through the dropper pin, and the warp breaks during weaving. A rod-shaped body that engages with the dropper pin that has fallen due to, forms an electric circuit including the engaging contact portion, and is in an energized state. The "divide rod" is a rod-like member that is provided between a plurality of rows of dropper pins and that partitions the dropper pins of adjacent rows so as not to interfere with each other.

The setting relationship between the distance L0 and the distance L1 will be described more specifically with reference to FIGS. 1 and 2. First, in the case shown in FIG. 1, the warp thread insertion hole 12 has a round hole shape. At this time, the interval L1 is from the upper end of the contact bar insertion hole 11 of the dropper pin 1 to the center of the warp insertion hole 12. However, in the case shown in FIG. 2, the warp thread insertion hole 12 is in the shape of a long hole opened downward. At this time, the interval L1 has a range of Lmax (the interval from the upper end of the contact bar insertion hole 11 to the lower end of the warp thread insertion hole 12) and Lmin (the interval from the upper end of the contact bar insertion hole 11 to the upper end of the warp thread insertion hole 12). It will be. Which of the intervals L1 is set within this range is appropriately determined at the design stage. In any case, the interval LO is set to be equal to or greater than the interval L1.
It is set smaller than the distance from the upper end of the contact bar insertion hole to the lower end of the dropper pin. That is, the contact bar is set in a state in which it can be engaged with the dropper pin.

Next, one embodiment of the mounting preparation device of the present invention will be described with reference to FIGS. In the illustrated machine preparation system, a drawing machine is used to drop the warp from the full warp beam to the dropper pin of the warp unit,
After passing through the heald and the reed, they are made to stand by on a stand equipped with a cross suspender as shown in FIG. At this time, the contact bar and the divide rod forming the warp stopping unit are suspended and supported, and in this suspended state, the intervals L0 and L1 are set to be equal to each other.

The cross suspension 71 on the stand 6 is composed of a horizontal bar 71a and a vertical bar 71b assembled in a cross shape with each other. A heald frame is supported on the horizontal member 71a, and one end of the reed is It is mounted on a hook 74 locked to the heald frame. Further, as shown in FIG. 5, a suspension member 72 is suspended and supported on the horizontal bar 71a. The suspension member 72 supports the contact bar 3, the divide rod 5 and the like via a suspension spacer 73. The horizontal member 71a is provided so that its vertical position can be adjusted along the vertical member 71b.

The hanging member 72 has a plurality of comb-teeth-shaped protrusions 72a which are directed downward and are arranged side by side in the front-rear direction (the warp threading direction). It has a pair of flange pins 72b. Further, hook-shaped support seats 72e for supporting the warp guiding pipe 75 are formed on the front and rear lower sides thereof. In addition, the upper end of the hanging member 72, via a pair of rollers 72c,
It is movably mounted on the horizontal rod 71a of the cross suspension 71, and its front and rear positions are fixed by fastening screws 72d.

The suspension spacer 73 is suspended and supported at the front and rear ends by the suspension member 72 via flange pins 72b. The hanging spacer 73 has a plurality of comb-teeth-shaped protrusions 73a that are directed upward and are arranged side by side in the front-rear direction, and a key-shaped hole 73b that opens upward is defined between the protrusions 73a.

The above-mentioned hanging member 72 and hanging spacer 73
In assembling with, the protruding portion 72a of the hanging member 72 is arranged so as to close the upper end of the hook-shaped hole 73b of the hanging spacer 73. Also, the adjacent protrusions 7 of the hanging member 72
One contact bar 3 is housed between 2a,
The contact bar 3 is attached to the protruding portion 7 of the hanging spacer 73.
3a supports from below. Further, one divider rod 5 is housed in each hook-shaped hole 73b of the hanging spacer 73. A large number of dropper pins 1 are inserted into and supported by each contact bar 3. The distance LO from the upper end of each contact bar 3 to the upper end of the corresponding divide rod 5 is equal to the distance L1 from the upper end of the contact bar insertion hole 11 of the dropper pin 1 to the warp insertion hole 12. As a result, the warp thread insertion hole 12 of the dropper pin 1 and the upper end of the divide rod 5 have substantially the same height.

Next, in the above system, the operation of transferring the warp stopping unit, the heald frame and the reed from the drawing machine to the stand 6 will be described. Here, the "drawing machine" is a machine for automatically passing the warp through the dropper pin, the heald, and the reed, and is composed of an elevator 8, a heald frame track 7, and a main body having a threading function. . Note that FIG. 3 shows a state at the time when the above threading is completed.

When working, first the lifting member 8 of the lift 8 is used.
Drop 1 Then, the heald frame track 7 is brought close to the elevator 8, and the hook at the upper end of the vertical rod 71b of the cross suspension 71 is hooked on the elevator member 81 of the elevator 8.

In this state, the elevating member 81 is raised and the cross suspension 71 is pulled out from the column of the heald frame track 7. Then, the heald frame track 7 is retracted from the elevator 8.

After that, the stand 6 on which the full warp beam B is placed is moved toward the elevator 8 and its supporting column 61 is moved.
Is positioned directly below the cross-shaped suspending tool 71 suspended from the elevating member 81. By lowering the elevating member 81 in this state, the vertical bar 71b of the cross hanger 71 is inserted into the column 61 on the stand 6, and the cross hanger 7 is removed from the elevating member 81. After that, the elevating member 81 is raised.

FIG. 4 shows the stand 6 in a state in which the cross suspension 71 is collected. At this time, the distance C between the warp stop unit and the heald frame is smaller than the distance D when the loom is attached to the loom. However, the fastening screw 72
By loosening d and horizontally moving the suspending member 72 together with the suspension unit on the horizontal bar 71a of the cross suspension 71, the distance between the suspension unit and the heald frame is as shown in FIG. 6 from C. Extended to D.

The dropper pin 1 squeezes the warp yarn T when the space is expanded. However, as described above, since the warp thread insertion hole 12 of the dropper pin 1 and the upper end of the divide rod 5 are supported at the same height, the sliding resistance is small and the warp stop unit can be easily moved. That is, since the warp yarns are not overly moved during movement, the damage can be avoided.

For the same reason, the warp beam B is rewound and the warp ends protruding from the reed are pulled out, and a film is welded to the warp ends to fix the warp ends without disturbing them. Without damaging the
It can be done easily.

In the subsequent work, the warp beam B and the cross hanger 71 are recovered from the stand 6 by a not-shown mounting device. After that, these are moved to the loom, and the warp beam B, the warp unit, the heald frame, and the reed are transferred to the loom. On the loom, there is a dropper box 9 as shown in FIG.
Is installed in advance. The dropper box 9 is composed of a bracket 91, a plurality of spacers 92 supported by the bracket 91 and arranged side by side in a direction orthogonal to the warp, and a pair of oval tubes 93 provided at front and rear ends. There is. Six spacers 3 are accommodated in each spacer 92, and five divider rods 5 are accommodated between adjacent spacers 92.

Next, another embodiment of the mounting preparation device of the present invention will be described with reference to FIGS. In the machine mounting preparation system shown in the figure, the stand collects the suture stop unit, the heald frame, and the reed from the cross suspension, and mounts and supports the suture stop unit and the heald frame. In the supported state, the distances L0 and L1 are set to be equal to each other. It should be noted that members having substantially the same functions as those in the previous embodiment are denoted by the same reference numerals.

In this embodiment, as shown in FIG. 6, a dropper box 9 as shown in FIG. 7 is preliminarily mounted on the stand 6, and the warp stopper unit is a suspension member 7.
It is removed from No. 2 and is housed in this dropper box 9. Here, by placing the contact bar 3 on the dropper box 9 on a pair of support tools, the warp thread insertion hole of the dropper pin 1 and the upper end of the divide rod 5 are positioned and supported at the same height. . Further, as shown in FIG. 6, a heald frame housing portion 76 is provided on the stand 6, and the heald frame is housed in the heald frame housing portion 76 after being removed from the cross hanger 71.

Next, an example of the arming preparation work by this system will be described. The configuration in which the warp stop unit is suspended is the same as that shown in FIG. First, the cross hanging device 71
The hanging member 72 is horizontally moved along the horizontal bar 71a of the above, and the distance C between the warp stop unit and the heald frame is increased.
To the distance D on the loom.

The cross suspension 71 is inserted into the support column 61 of the cradle by the same procedure as in the first embodiment. As described above, on the stand 6, the distance between the placing portion 76 of the heald frame and the dropper box 9 has already been set to the same D as when the loom was installed.

Then, the hooking unit, the heald frame, and the reed are transferred from the cross hanger 71 onto the stand 6. The state during this period is shown in FIG. In addition, cross hanging device 7
1 is not inserted into the column 61 of the cradle, and the cross suspender 71 is hooked on the elevating member 81 so that the warp unit, the heald frame and the reed are transferred from the cross suspender 71 to the cradle. The lower end of the vertical bar 71b of 71 may be shortened. When the transfer is completed, the cross suspension 71
Remove from the stand 6. Then, as shown in FIG. 8 and FIG.
The contact bar 3 is supported by a pair of supporting tools 94. In this state, since the warp thread insertion hole 12 of the dropper pin 1 and the upper end of the divide rod 5 are supported at the same height position, the resistance against relative movement between the dropper pin 1 and the warp thread T is reduced. Therefore, for example, the work of pulling out the warp while rewinding the warp beam B becomes easy.

Then, the warp beam B, the dropper box 9 accommodating the warp stopping unit, the heald frame and the reed are transferred from the stand 6 to a mounting device (not shown). After that, after moving to the loom, these are collectively transferred to the loom.

In order to extend the distance C between the warp unit and the heald frame to the distance D when the loom is installed, in the second embodiment, the warp unit is moved on the cross suspension 71. ing. However, in the case of a fluffy warp, it may be difficult to move the warp even if the present invention is adopted. In such a case, as shown in FIGS. 10 and 11,
A pair of temporary placement tools 95 placed on the support plate 62 fixed to the upper ends of the columns 61 of the stand 6 are used. That is, the contact bars 3 are once placed on the temporary placement tool 95, and the contact bars 3 are transferred to the dropper box 9 one by one, thereby expanding the interval (from C to D) as described above. I'll do it. That is, the distance C between the warp stopping unit and the heald frame is transferred to the stand 6 and the distance is expanded to D as described above.

In the example shown in FIGS. 12 and 13, instead of the temporary placement tool 95, the receiving tool 96 is fixed on the stand 6, and the hanging spacer 73 with the latch 73a is removed from the hanging member 72. And is inserted into the receiving tool 96 from above. The subsequent procedure for expanding the interval is similar to the above case.

[0033]

Since the relative movement of the warp yarn and the dropper pin is facilitated, the workability of the work requiring such relative movement is greatly improved. Moreover, for that purpose, since the support state around the warp stop unit is simply changed from that of the conventional one, the structure related to the stand is not particularly complicated.
