Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for converting a spinning machine. To be more specific, two newly prepared full bobbins at the Shino of the small ball bobbin being spun on the front and rear of the creel of the spinning machine are spouted and spliced together. The present invention relates to a method for replacing a pair of front and rear small bobbins during spinning.

[0002]

2. Description of the Related Art When a Shinobaki bobbin hung on a bobbin hanger of a spinning machine becomes empty or becomes a small bobbin, the Shinobaki bobbin is replaced with a full bobbin. It is necessary to put out the full end of the bobbin and connect it to the end of the small bobbin, or insert the full end of the full bobbin into the drafting part of the spinning machine again.

[0003] In order to save labor in the spinning process, automation is also required for the process of connecting and replacing the spinning machine. For example, in Japanese Patent Laid-Open No. 61-102428, the spare rails are arranged in two rows in the front and rear, and a pair of front and rear bobbins hung on bobbin hangers in the front and rear rows of the spinning machine are combined with full bobbins on the two rows of spare rails. A method of sequentially changing the machine frame from one end to the other end of the spinning machine is disclosed. In Japanese Patent Laid-Open No. 61-119728, a bobbin is provided along the longitudinal direction of the machine frame of the spinning machine instead of arranging the spare rails in a row. A method is disclosed in which a pair of front and rear bobbins and a full bobbin on a spare rail are replaced every other pitch. However, the methods disclosed in the above-mentioned two publications only perform the changeover automatically, and the extension of the end of the end and the connection of the end must be performed manually as before.

The applicant of the present invention filed on Sep. 10, 1985 under the name of "method of replacing a spinning machine" in order to automate the sword end and sewage joint work.
In Japanese Patent No. 2928, at least two full bobbin Shino ends on a spare rail are squeezed out by a Shino exchange running along a machine base and spliced to at least a pair of front and rear small ball bobbins being spun during spinning. At the same time, we are proposing a method to exchange those full bobbins and small bobbins. This method is an excellent method that helps to achieve complete automation of the Shino-exchange and Shino-joining process in the spinning machine, but because the sashimi, Shino-tsuki, and Shino-changing operations are performed in series at the same location, There is a problem that the structure of the exchange becomes complicated and the processing time of the replacement work becomes long. Therefore, the present invention provides a Shino conversion method in which the Shino end finding work and Shino replacement are performed in parallel at different places to shorten the processing time of a series of Shino replacement works, and which can be performed by an extremely simple device. The purpose is to provide.

It employs a configuration in which no work is performed.In that case, the full bobbin of the spare rail and the small bobbin of the creel are mechanically moved from one end of the spinning machine to the other end without any human intervention. Can be exchanged.

In addition, in addition, in the front and rear bobbin hanger pair rows of the creel, the plurality of adjacent front and rear small bobbin pairs are used as work units so that work can be performed simultaneously. In this case, since the full bobbin and the small bobbin are replaced in pairs, the entire spinning machine can be replaced in a short time.

It is a schematic plan view which shows order (relationship position).

Therefore, the working procedure in this embodiment is that, for the same full bobbin and the small bobbin, the shin end exiting work and the shino joining work shown in the middle stage are performed, and then the lower shino exchange work is performed. Actually, however, as shown in the figure, the middle end Shino end exiting / joining work and the lower Shino exchange work are performed in parallel with each other on another full bobbin and small bobbin.

[0012] In carrying out the method of changing the sash according to the present embodiment, the bobbin hangers on the front and rear rows of the creel of the spinning machine are arranged such that full bobbins and medium bobbins are alternately arranged in front and back to form a pair. Figure 1
As shown in (1), the pair of front and rear Shino-maki bobbins F ₂ and B ₂ are small bobbins. At this time, as shown in the middle of FIG. 1 (1), Shino r _1, r ₂ from Kodama bobbins F _2, B ₂ is supplied via a roving guide 3 trumpet 2 upstream of the drafting unit 1 of the spinning machine Is spun out. In the figure, 10 is a Shino exchange, 4a and 4b are pegs for supporting the respective full bobbins M ₁ and M ₂ when moving them, and 5a and 5b are full bobbins M ₃ that have been spliced after the Shino end exit, The pegs support the small bobbins F ₂ and B ₂ and the full bobbins M ₃ and M ₄ when moving the small bobbins F ₂ and B ₂ to exchange M ₄ with the small bobbins F ₂ and B ₂ .

These pegs 4a, 4b and peg 5
Each of a and 5b is supported by a Shino end exit and Shino joint operation mechanism or Shino conversion operation mechanism that operates independently or in association with each other in the Shino exchange, enabling vertical movement, front-rear movement, left-right movement and rotation. There is. Reference numeral 6 is a Shino joint head for connecting the Shino ends of the full bobbins M ₁ and M ₂ to Shino r ₁ and r ₂ of the small bobbins F ₂ and B _{2 being} spun, and 7a and 7b are full bobbin M ₁ and It is a suction nozzle that draws out the tip from M ₂ .

Although a shinko hanging plate is used when performing the shino exchange, only the movement locus (see the lower part of FIG. 3 (5)) is shown and omitted for simplification of the drawing. Incidentally, an example of the structure of the peg, Shinotsu head, etc. was filed by the same applicant as the applicant on August 31, 1985 under the name of "Shino exchange method in spinning machine".
Since it is described in detail in Japanese Patent Publication No. 26, the operation thereof will be described hereinbelow.

The pair of small bobbins F ₂ and B _{2 in} front and rear are in a state in which the number of remaining pieces is small and need to be replaced. As shown in the upper part of FIG. The head 6 stops at a position with respect to the small bobbins F ₂ , B ₂ . Figure 1 (2) pegs 4a, 4b is increased full bobbin M ₁ which is suspended on the bobbin hanger of the pre rail obliquely forward direction as shown in the upper and middle when this happens, M ₂ Remove and lower to return to the original position. The SaiMitsuru bobbin M _1, M ₂ are pegs 4a such that the distance between the full bobbin M _1, M ₂ is expanded in order to facilitate the withdrawal of Shino end below, may 4b is moved. At that time the suction nozzle 7a, 7b GaMitsuru bobbin M _1, M ₂ suction to pull the Shino end from the time the pegs 4a, 4b are full bobbin M ₁ by being rotated by the rotation means in the mechanism for supporting the peg , M ₂ is rotated in the rewinding direction of Shino.
In this case, since the full bobbins M ₁ and M ₂ are lowered to a lower position, the amount of ascent of the suction nozzles 72 and 76 can be reduced, the size of the device can be prevented from increasing, and the dispensing operation can be facilitated.

Next, the Shino-joint head 6 extending between the full bobbins M ₁ and M ₂ and the respective suction nozzles 7a and 7b (in the figure, two Shino-joint heads are provided for simplification of the drawing). However, in reality, the Shino joint heads are arranged and operate corresponding to the respective Shino joints), and then the Shino joint head 6 is cut to form the Shino end. Then, while swinging in the clockwise direction as shown by the arrows in the upper and middle stages of Fig. 2 (3), the shining end is guided above the trumpet 2 and the small balls bobbins F ₂ and B ₂ being spun ₁ , r
_When the Shinobashi end of the full bobbin is overlapped with ₂ , the Shinobashi of the full bobbin is released to perform Shino splicing (upper and middle stages in Fig. 2 (4)). Shino r ₁ and r ₂ of the small bobbins F ₂ and B ₂ are grasped and cut by the Shinotsu head.

Then, as shown in the upper and middle stages of FIG. 3 (5), the Shinobu head 6 swings counterclockwise and returns to its original position. The full bobbins M ₁ and M ₂ are rotated in the rewinding direction so as not to break the shinko when moving the hinoki joint head 6, or in the winding direction so that the shinko does not become loose. Next, in order to suspend the full bobbins M ₁ and M ₂ that have been spliced to each other on the bobbin hanger of the spare rail, the pegs 4a and 4b are raised diagonally in the forward direction and the mutual intervals are narrowed to reduce the full bobbin M.
Attach ₁ and M ₂ to the bobbin hanger of the spare rail (Fig. 3
(6) (upper and middle), and then the pegs 4a and 4b are lowered and stored in the original position (upper and middle of FIG. 3 (7)).

Next, as shown in FIG. 1 (1), the work procedure for replacing the full bobbin and the small bobbin that have already been spliced together will be described.
This will be described below with reference to the upper and lower drawings of FIG. Incidentally, a pair of pegs 5a, 5b for shino exchange of this embodiment.
Is stored in the front position corresponding to the small bobbin to be replaced as shown in the upper part of FIG.

The pegs 5a and 5b are provided on a peg unit that moves forward and backward, and the interval between the pegs changes during the forward and backward movements of the peg unit, and at the forward end the distance between the bobbin hangers before and after the creel becomes the lower position of the spare rail. In the upper and lower positions of FIG. 1 (2) and FIG. 3 (5), the bobbin hangers of the spare rail are spaced. Then, rotate the peg unit 90 ° and move the peg unit forward slightly, and it will correspond to the position directly below the empty bobbin hanger on the spare rail (the empty bobbin hanger after the previous full bobbin has been removed).
When the peg unit is rotated 180 °, it corresponds to the position directly below the full bobbin that is suspended on the spare rail by the Shino end opening / sinking joint work described above. When the peg unit is further rotated 90 °, the spare rail is rotated. It is designed to return to the lower position of. Since the device is pending, a detailed description will be omitted.

As shown in the lower part of FIG. 1 (1), the full bobbins M ₃ and M which have been spliced to reach the trumpet.
₄ is mounted on the bobbin hanger of the spare rail. Next, the pegs 5a and 5b are directed toward the machine frame of the spinning machine as shown by the arrows in the upper and lower parts of FIG. 1 (2) in order to remove the small bobbins F ₄ and B ₄ from the bobbin hanger of the creel of the spinning machine. It moves forward, rises, engages with the lower ends of the small bobbins F ₄ , B ₄ , removes the small bobbins, then descends, and then moves backward. At this time, the pegs 5a, 5b are rotated by a rotating means in a mechanism for supporting the pegs 5a, 5b to wind up the remnants hanging from the small bobbins F ₄ , B ₄ .

Next, the peg unit is rotated by 90 ° so that the small bobbins F ₄ and B ₄ on the pegs 5a and 5b correspond to positions directly below the empty bobbin hangers on the spare rails (FIG. 2 (3), upper and lower stages). . Then pegs 5a, 5b
Goes up and attaches the small bobbins F ₄ and B ₄ to the empty bobbin hangers on the spare rails (Fig. 2 (4) upper and lower stages).

Next, the peg unit is rotated 180 ° and the peg 5 is placed directly below the full bobbins M ₃ and M _{4 on} the spare rail.
The full bobbins M ₃ and M ₄ are removed from the bobbin hanger of the spare rail by ascending and descending after associating a and 5b. Next, move the peg units of pegs 5a and 5b 90 °
The pegs 5a and 5b face (vertical same plane) in front of a pair of front and rear bobbin hangers of the creel from which the small bobbin has been rotated to remove the small bobbin (top and bottom in FIG. 3 (5)).

[0023] It should be noted that the peg 5a in order to eliminate the slack of Shino from the SaiMitsuru bobbin M _3, M _4, 5b is full bobbin M
₃ and M ₄ rotate in the winding direction, while full bobbins M ₃ and M
_In order to hook the Shino from ₄ on the roving guide 3, the Shino hanging plate reciprocates as shown by the arrow in the lower part of Fig. 3 (5). Peg 5a to avoid the tension Shino from its SaiMitsuru bobbin M _3, M ₄ is abnormally large, 5b rewind.

Next, as shown in the upper and lower stages of FIG. 3 (6), the peg unit is moved forward, and the pegs 5a and 5b supporting the full bobbins M ₃ and M ₄ are directly below the bobbin hangers before and after the creel of the spinning machine. After moving forward until it reaches the position, the bobbins M ₃ and M ₄ are lifted and mounted on a pair of front and rear bobbin hangers of the creel of the spinning machine. After that, the pegs 5a and 5b descend and retreat to return to their original positions in the Shino exchange (Fig. 3 (7)). Thus, a series of Shino end exit, Shinotsu and Shino exchange work is completed, and this work is continued from one end of the spinning machine to the other end.

FIG. 4 shows a second embodiment of the conversion method according to the present invention.
Shown in FIG. 4 shows only the drawing of FIG. 1 (1) showing the work procedure of the first embodiment, and the work procedure after that is shown in FIG.
Since it is substantially the same as (2) to FIG. That is, the upper part of Fig. 4 (1) shows the relative positions of the full bobbin, the small bobbin, the peg, the suction nozzle, the Shino joint head, etc. in the Shino end exit, Shino joint, Shino exchange work.
The middle row is a schematic side view showing the relative positions of the respective members when the full bobbins M ₁ and M ₂ arranged in a staggered state on the spare rail are in a state immediately before being spliced. Four

FIG. 9 is a schematic side view showing the relational positions of the respective members just before M ₄ are arranged in a staggered state on the auxiliary hanger and immediately before being replaced with small bobbins F ₄ and B ₄ .

In the second embodiment, the full bobbins are arranged in a zigzag state on the spare rail. Therefore, the diameter of the full bobbin is
There is an advantage that it can be made larger than the bobbin hanger pitch in the longitudinal direction of the spinning machine creel. Since the work procedure of the Shino end exit, Shinotsu, and Shino exchange is substantially the same as that of the first embodiment, detailed description will be omitted.

5 to 7 show the work procedure of the third embodiment of the reshuffling method according to the present invention (FIG. 5 (1) to FIG. 7).
(7)). In the third embodiment, the full bobbins M ₁ , M ₂ , M ₃ and M ₄ to be replaced are arranged in two rows along the machine frame of the spinning machine, so that on the creel of the spinning machine. When the Shino-maki bobbin hung on the bobbin hanger becomes a small bobbin, from the one end of the machine frame of the spinning machine to the other end (from bottom to top in the top plan views of Figs. 5 to 7) This is a Shino exchange method that allows Shino-Hataguchi, Shinotsu, and Shino exchange. The steps will be described below in order.

The relationship among the upper, middle and lower stages in each of FIGS. 5 (1) to 7 (7) is shown in FIG.
It is the same as (1) to FIG. 3 (7), that is, the work procedure of the Shino end exit and Shino joint in the middle stage, and the work procedure of Shino exchange between the full bobbin and Kodama bobbin already joined in the lower stage are schematically shown. It is shown in a side view, and the upper part shows the work procedure of both in a plan view.

When carrying out the method of replacing the bobbin according to the third embodiment, the bobbin hangers of the creel of the spinning machine are suspended from the bobbin of the same diameter, usually a full bobbin, to start spinning. The middle part of FIG. 5 (1) shows a state in which the full bobbins hanging on the bobbin hanger on the creel of the spinning machine become small bobbins F ₁ and B ₁ as the spinning progresses. In this state, the shino r ₁ and r ₂ from the small bobbins F ₁ and B ₁ are supplied to the trumpet 2 upstream of the drafting section 1 of the spinning machine through the roving guide 3 and spun.

As in the first embodiment, the pegs 5a and 5b change the peg spacing during the forward and backward movement of the peg unit. At the trailing end of the peg unit, it corresponds to the position directly below the empty bobbin hangers in the front and rear rows of the spare rail, and the peg unit is rocked to the left and right to correspond to the position directly below the full bobbin on the spare rail and return to the original position. I'm supposed to come back. 6
Is a head joint, and 7a and 7b are suction nozzles.
The pegs 4a, 4b; 5a, 5b, the connecting head 6, and the suction nozzles 7a, 7b are the same as in the first embodiment, and are described in detail in the above-mentioned JP-A-62-53426. Therefore, in the present specification, only the operation will be described below.

As shown in the middle part of FIG. 5 (2), when performing the Shino end exit and Shino joint according to the third embodiment, the Shino joint head 6 is stopped at a position corresponding to the small bobbins F ₂ and B ₂ .
Pegs 4a in this state, 4b is off the bobbin hanger bobbin full and is suspended in M _1, M ₂ on the spare rail rises narrowed mutual spacing, and其後descends and returns to the original position . Therefore drawer Shino end later been expanded is full distance of the bobbin M _1, M ₂ is in a state of returning to the original position is facilitated. In the mechanism in which the suction nozzles 7a and 7b move in the middle part of FIG. 5 (2) as shown by arrows to suck and pull out the shin end from the full bobbins M ₁ and M ₂ , and at the same time, the pegs 4a and 4b support the pegs. The full bobbins M ₁ and M ₂ are rotated in the rewinding direction by rotating them by the rotating means.

Next, the Shino joint head 6 grips the Shino joint head 6 which extends between the full bobbins M ₁ and M ₂ and the respective suction nozzles 7a and 7b. 6 (3), the Shino joint head is oscillated in the clockwise direction as shown by the arrows in the upper and middle sections of FIG. 6 (3), and its shin end is guided above the trumpet 2 to spout small balls. The Shino ends of the bobbins F ₂ and B ₂ are overlapped on the Shino r ₁ and r ₂ and the Shino joint is performed as described above (the upper and middle rows of Fig. 6 (4)), and the small bobbin upstream of the Shino joint. F ₂ , B
₂ Shino r ₁ and r ₂ are cut off.

Next, as shown in the upper and middle stages of FIG. 7 (5), the Shino joint head 6 swings counterclockwise and returns to its original position. The full bobbins M ₁ and M ₂ are rotated in the rewinding direction so that the Shinobu head 6 is not cut when moving.
It is rotated in the winding direction so that the looseness of Shino does not become too large. Next, peg 4 is used to suspend the full bobbins M ₁ and M ₂ that have been spliced on the bobbin hanger on the spare rail.
a and 4b perform mutual reduction and upward movement to mount the full bobbins M ₁ and M ₂ on the bobbin hanger of the spare rail (upper and middle stages of FIG. 7 (6)), and then pegs 4a and 4b. Is lowered and is stored in the original position (the upper and middle stages of FIG. 3 (7)).

Next, the working means for replacing the full bobbin and the small bobbin that have been spliced together as described above will be described with reference to FIGS.
(7) Description will be made with reference to the upper and lower drawings. Figure 5
As shown in the lower part of (1), the full bobbins M ₃ and M ₄ which have already been spliced and have reached the trumpet 2 are mounted in two rows in the front and rear on the bobbin hanger of the spare rail.

Next, the pegs 5a and 5b are small bobbins F ₄ ,
B ₄ In order to remove from the bobbin hangers of the creel of the spinning machine, FIG. 5 (2) lower in as indicated by arrow, to advance towards the machine frame of the spinning machine, Kodama bobbins F ₄ rises, B ₄ It engages with the lower end of the and removes the small bobbin, then descends and then retreats.
At this time, the pegs 5a, 5b are rotated by a rotating means in a mechanism for supporting the pegs 5a, 5b to wind up the remnants hanging from the small bobbins F ₄ , B ₄ .

After that, the pegs 5a and 5b are lifted in the vertical direction, and the small bobbins F ₄ and B ₄ are mounted on the pair of front and rear bobbin hangers directly above the spare rail (FIG. 6 (3) lower stage). Pegs 5a, after 5b is a slightly downward in order to deviate from the bobbin F _4, B ₄ Kodama, adjacent to a pair of bobbin hangers before and Kodama bobbins F _4, B ₄ is mounted immediately before on the pre-rail, and already The full bobbins M ₃ and M ₄ joined together are moved to a position below a pair of front and rear bobbin hangers on which the bobbins M ₃ and M ₄ are suspended, as shown by an arrow in the upper part of FIG. 6 (4).

[0038] Thereafter pegs 5a, 5b returns elevated full bobbin M ₃ are, M ₄ and the lowered original position removed from the bobbin hanger of the preliminary rails. In this state, the pegs 5a, 5
The full bobbins M ₃ and M ₄ on b are the small bobbins F ₂ and B _{2 first.}
Since the bobbin hanger is displaced by one pitch in the longitudinal direction of the spinning machine from the position of a pair of front and rear bobbin hangers on the creel of the spinning machine that was removed, the pegs 5a and 5b are shown in order to return the position to the original position. 7 (5) Move to the upper row as indicated by the arrow.

[0039] Note that when the movement of the full bobbin M _3, M ₄ is full bobbin M _3, pegs 5a to eliminate loosening of Shino from M _4, 5b is a full bobbin M _3, M ₄ in the winding direction On the other hand, the shining plate is rotated to rotate the shining plates from the full bobbins M ₃ and M ₄ on the roving guide 3 as shown in FIG. 7 (5).
Reciprocate as indicated by the arrow in the lower part of the drawing. At this time, rotate the full bobbin in the rewinding direction to loosen the shin so that it does not break.

Next, as shown in the upper and lower parts of FIG. 7 (6), the pegs 5a and 5b supporting the full bobbins M ₃ and M ₄ are arranged such that their intervals correspond to the intervals of the bobbin hangers before and after the creel of the spinning machine. Then, the full bobbins M ₃ and M ₄ are mounted on the pair of front and rear bobbin hangers of the creel of the spinning machine. After that, the pegs 5a and 5b descend and retreat to return to their original positions in the Shino exchange (Fig. 3 (7)).

Thus, a series of Shino end exit, Shinotsu and Shino exchange work is completed, and thereafter this work is continued from one end of the spinning machine to the other end. However, in any embodiment, it goes without saying that only the Shino end exit and Shino joint work is performed at the beginning and only the Shino exchange work is performed at the end. In the above-described first embodiment, this work is performed every other pair of front and rear bobbin hangers on the creel of the spinning machine, and half the small bobbins on one side of the machine base are replaced with full bobbins. Then, all the small bobbins on one side of the machine stand are replaced with full bobbins.

As described above, the work of the Shino end exit and Shino joint of the middle stage and the Shino exchange work of the lower stage are performed in parallel at the same time, but the timing of the work procedure does not have to be the same as in the middle lower stage of the figure. Needless to say. The present invention achieves its object by performing the Shino end exit and Shino joint work and Shino exchange work at different places substantially in parallel, and the embodiment is only one example. For example, in the above embodiment, since Shino exchange may be performed within Shino end exit and Shino joint time, Shino exchange is performed with a pair of pegs 5a and 5b in order to simplify the structure and downsize the Shino exchange. Known JP-A Nos. 61-102428 and 61-119.
You may use two sets of pegs for small bobbin and full bobbin like No.728.

In addition, in order to prevent the shin end of one full bobbin from being entangled with the other full bobbin at the time of shinotsugi, and widen the interval between the full bobbins taken out from the spare rail in order to ensure the extension of the shin end. Although the tip of the Shino end is exposed (the upper step of (2) in FIGS. 1 and 7), this step may be omitted depending on the gap between the full bobbins hanging on the spare rail.

[0044]

As described above, according to the present invention, a series of reshuffling work in a spinning machine is divided into first and second work, and these first and second work are simultaneously performed in parallel. The processing time for a series of replacement jobs can be shortened, and the work capacity can be greatly increased. Also, in the first work, the full bobbins are removed from the bobbin hanger and lowered, and the shining ends of the full bobbins are squeezed out in this lowered state, so it is easy to squeeze the squirting ends of the full bobbins at a low position. And surely. After finishing the mouth in the first work, raise the pair of full bobbins and hang them again on the bobbin hanger of the spare rail,
In the second work, the full bobbin and the small bobbin that are suspended on the spare rail are replaced by the previous replacement work, so the first and second works can be easily performed by a simple mechanism.
