Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method for converting a spinning machine. More specifically, the present invention relates to a method for replacing the Shino-Rom bobbins suspended from two rows of bobbin hangers on the front and rear with two newly prepared full bobbins for each pair of front and rear bobbins.

[Conventional technology and its problems]

When the Shinobaki bobbin hanging on the bobbin hanger of the spinning machine becomes empty or becomes a small bobbin, the Shinobaki bobbin is replaced with a full bobbin, and the full bobbin Shino is replaced with a small bobbin Shino. It is necessary to splice or insert the full bobbin into the drafting section of the spinning machine again.

On the other hand, in spinning factories, automation of each process is progressing in order to further save labor, and the demand for the automation extends to the Shino exchange / Shinetsu process in the spinning machine. A conventionally known automatic reshuffling method, for example, as disclosed in Japanese Patent Laid-Open No. 60-71724, sets the same size of shinomaki for each of the front row and the rear row of the creel of the spinning machine and spins them (for example, the front row). When the bobbin in the front row becomes a small bobbin, there is a method to replace the small bobbin with a full bobbin on the spare rail that is located just above the bobbin position in the front row of the creel. Are known. However, this replacement method requires a replacement operation of replacing the small bobbin in the front row with a full bobbin and then moving the bobbin that is the middle ball in the back row to the front row in preparation for the next replacement. In addition to complicating the work involved in the replacement, there was a problem with the equipment that Shino's front and rear replacement machines had to be installed on the spinning machine.

Further, in the spinning machine adopting the above-mentioned reshuffling method, the bobbin hangers in the front row or the rear row are always hung with the same size of bobbin hangers, so that the maximum diameter of the full bobbin is the bobbin hanger pitch of the creel. Inevitably, the large bobbin packaging is restricted by the bobbin hanger pitch value of the creel of the spinning machine.

[Object and Summary of Invention]

Therefore, the present invention is a method for replacing the bobbins in the front row and the rear row of the creel, and if the method is used, a bobbin having a shining diameter larger than the bobbin hanger pitch of the creel is used. It is an object of the present invention to provide a method of reshuffling that makes it possible.

A first invention is a spinning machine for exchanging a full bobbin in a single row suspended on a bobbin hanger on a spare rail provided in front of the creel and a bobbin suspended on two bobbin hangers before and after the creel. When the pair of front and rear Shinobaki bobbins become small bobbins, the Shino exchange that runs intermittently from one end of the machine base to the other is stopped at a predetermined replacement work position, and the replacement is performed. At the work position, at least a pair of front and rear small bobbins are simultaneously removed from the creel by the Shino exchange, and then at the crease small bobbin removal position, at least two corresponding full bobbins on the spare rail are moved toward the machine base by the Shino exchange. Are suspended in the front row of the creel, and the left ones are simultaneously suspended so that they are located in the rear row of the creel, respectively. Wherein the sequentially performed at each replacement operation position toward the end.

A second invention is a spinning machine for exchanging a full bobbin in a single row suspended on a bobbin hanger of a spare rail provided in front of the creel and a bobbin suspended on two bobbin hangers before and after the creel. When the pair of front and rear Shinobaki bobbins become small bobbins, the Shino exchange that runs intermittently from one end of the machine base to the other is stopped at a predetermined replacement work position, and the replacement is performed. At the working position, at least one pair of front and rear small bobbins are simultaneously spliced with the corresponding full bobbin ends of the spare rails by the Shino exchange.
After that, at least one pair of front and rear small bobbins after the shino connecting by the Shino exchange are simultaneously removed from the creel by the Shino exchange, and then at least two full bobbins corresponding to the spare rails are installed at the removal position of the creel or empty bobbin by the Shino exchange. To the platform, the right one is suspended in the front row of the creel and the left one is suspended in the rear row of the creel at the same time. It is characterized in that it is sequentially performed at each replacement work position.

As shown in the lower side view of FIG. 6), the full bobbins M ₁ and M ₂ supported by the pegs 4a and 4b, which have been retracted, move to the precise position as shown in the upper layout of FIG. 1 (6). It moves in the longitudinal direction of the spinning machine and returns to its original position. Next, move the bobbins M ₁ and M _{2 to} the shino R ₁ and R ₂ roving guide 3
In order to hang each of them, a shining plate (not shown) moves along the trajectory of the arrow shown in the lower side view of FIG. 1 (7). Its SaiMitsuru bobbin M _1, M Shino R ₁ of _2, R ₂ is pegs 4a so as not to cut, 4b GaMitsuru rotating bobbin M _1, M ₂ in the rewinding direction. Next, in order to suspend the full bobbins M ₁ and M ₂ to the corresponding bobbin hangers of the creel of the spinning machine, the full bobbins M ₁ and M ₂ are moved to the positions below the bobbin hangers. At that time, the two full bobbins M ₁ and M ₂ were arranged in the zigzag state up to that time, so that they should be lined up in a row in front and rear in FIG. 1 (8).
As shown by the arrow in the upper diagram of the machine, the full bobbins M ₂ on the left side toward the machine stand in the rear row and the full bobbin M ₁ on the right side toward the machine stand in the front row while being moved toward the center side so as not to interfere with each other. Change the distance of movement so that it comes to, and move forward. At that position, the pegs 4a, 4b move up to hang the full bobbins M ₁ , M ₂ on their respective bobbin hangers, then descend and then move back to positions 5a, 5b in Fig. 1 (1). On the other hand, the pegs 5a, 5b for the small bobbin also descend and return to the positions 4a, 4b in Fig. 1 (1), and the Shinotsu heads 6a, 6b rotate counterclockwise to return to their original positions ( Fig. 1 (9)). As can be seen by comparing FIGS. 1 (1) and 1 (9), the pegs 4a, 4b for full bobbins shown in FIG. 1 (1) have completed one reshuffling. ), The peg for the small bobbin shown in Fig. 1 (1)

It should be noted that the embodiments described full bobbin M ₁ M ₂ of FIG. 1 (4) is retracted rightward upward layout (FIG downward), the full bobbin M ₃ M ₄
By retracting to the left (upward in the figure), two pairs of front and rear small bobbins F ₂ B ₂ and F ₄ B ₄ can be simultaneously replaced.

FIG. 2 shows a work procedure of a second embodiment of the reshuffling method according to the present invention (FIGS. 2 (1) to 2 (9)). As can be seen by comparing FIG. 2 with FIG. ₁ , the arrangement states of full bobbins M ₁ , M ₂ , M ₃ , M ₄ and small bobbins F ₁ , F ₂ , F ₃ , F ₄ in the second embodiment. Is the same as that of the first embodiment. The difference from the first embodiment is that the full bobbin and the small bobbin are moved, but in the first embodiment, the full bobbin peg and the small bobbin peg are moved. In the second embodiment, only one pair of pegs is used for loading and unloading the Shino winding bobbin to and from the spinning machine. In addition, the fork 8 for vertically moving the Shino winding bobbin and the Shino winding bobbin are used. The difference is that the hangers 7a and 7b are used for temporary holding to divide the functions. The steps will be described below in order.

In Fig. 2 (1), as in Fig. 1 (1), the pair of front and rear small bobbins F ₂ and B ₂ has a small amount of remaining shinko, and the shino exchange 10 is in the state where shino exchange is required. Stop in position.

Previously Dzu Kodama bobbins F _2, B ₂ pegs 5a to disengage from the respective bobbin hangers of the creel of the spinning machine, 5b reaches the lower Kodama bobbins F _2, B ₂ corresponding forward. Next, the fork 8 advances a little and then rises to reach the full bobbins M ₁ , M on the spare rail as shown by the arrow in the upper layout of FIG. 2 (2).
Remove ₂ and go down. At that time the second diagram (1) hangers 7a was in indicated away with, 7b pending temporary its position full bobbin M _1, M ₂ is inserted into the full bobbin M _1, M ₂ are biassing Then, the fork 8 moves backward. Shino R _1, R ₂ from the full bobbin M _1, M ₂ is sucked by the suction nozzle, whereby hangers 7a, 7b GaMitsuru bobbin M _1, Shino from M ₂ R _1, R ₂ is rotated so rewound (Fig. 2 (2)). Next FIG. 1 (3) in the case as well as the full bobbin M _1, M ₂ and Shino R ₁ extending between each of the suction nozzles, R ₂ a ShinoTsugi head 6a, 6b is grasped and then rotated clockwise While making the width, the Shino end is guided to the trumpet 2 where the Shino r ₁ and r ₂ of the small ball bobbins F ₂ and B ₂ are spliced. At this time, the hangers 7a and 7b rotate to rewind the shino R ₁ and R ₂ from the full bobbins M ₁ and M ₂ (FIG. 2 (3)). In order to advance the space for taking out the small bobbins F ₂ and B ₂ from the spinning machine, the hangers 7a and 7b are shown by arrows in the upper layout of FIG. 2 (4) while holding the full bobbins M ₁ and M ₂ . Evacuate away from each other. Meanwhile pegs 5a, 5b is lowered downwardly from the bobbin hangers of the creel of the spinning machine Kodama Remove the bobbin F _2, B ₂ and rise. Shino r ₁ of the Saishino is cleaved by splicing Kodama bobbins F _2, B ₂ Kodama and down hanging from a bobbin F _2, B _2, r
₂ is wound by rotating the pegs 5a and 5b (Fig. 2 (4)). In order to mount the small bobbins F ₂ and B ₂ on the bobbin hanger of the spare rail, the pegs 5a and 5b are retracted, and the position immediately below the corresponding bobbin hanger of the spare rail as shown in the upper layout of FIG. 2 (5). The small bobbins F ₂ and B _{2 which} have moved to and have reached this position are gripped by the forks 8 (FIG. 2 (5)). The fork 8 moves up and hangs the small bobbins F ₂ and B ₂ on the bobbin hanger of the spare rail, and then descends and retreats to return to the original position. Hanger 7
The full bobbins M ₁ and M ₂ gripped by a and 7b rise slightly,
Then, the width is adjusted (Fig. 2 (6)). In this state, the full bobbins M ₁ and M ₂ have reached just above the pegs 5a and 5b, so by slightly lowering the next hangers 7a and 7b, the full bobbins M ₁ and M ₂ move to the pegs 5a and 5b. Supported. Meanwhile Shino hanging plate exerts a second view (7) Shino R ₁ of the lower side full bobbin M ₁ moves along the locus shown in FIG, M _2, R ₂ in the roving guide 2 (FIG. 2 (7) ). The full bobbins M ₁ and M ₂ are moved by the pegs 5a and 5b just below the bobbin hanger of the creel of the spinning machine along the trajectory shown by the arrow in the upper layout of FIG. 2 (8) as in FIG. 1 (8). Move to position. On the other hand, the hangers 7a and 7b also move left and right and return to their original positions (Fig. 2 (8)). Peg
As the 5a and 5b rise, the full bobbins M ₁ and M ₂ are suspended on the bobbin hanger of the spinning reel creel, and then the pegs 5a and 5b.
b descends and then retreats and returns to the original position, and the Shinobu heads 6a and 6b rotate counterclockwise to return to the original position (Fig. 2 (9)). Thereafter, the above work is repeated to replace half of the spinning machine.

FIG. 3 shows a work procedure of a third embodiment of the reshuffling method according to the present invention (FIGS. 3 (1) to 3 (15)). As can be seen by comparing FIG. 3 with FIG. ₁ , the arrangement states of full bobbins M ₁ , M ₂ , M ₃ , M ₄ and small bobbins F ₂ , B ₂ , F ₃ , F ₄ in the third embodiment. Is the same as the first embodiment, except that the pegs 4a, 4b and the hangers 7a, 7b are used to move the shinomaki bobbin.
The steps will be described below in order.

In FIG. 3 (1), the small bobbins F ₂ and B ₂ are in a state requiring shino exchange, and the extension exchange 10 is stopped at the shino exchange position. Then peg 4a, 4b rises full bobbin M ₁ from the bobbin hanger of the preliminary rail, M ₂ was removed and lowered, whereas Shino R ₁ in both disposed obliquely full bobbin M _1, M _2, R ShinoTsugi head 6 serving as a suction nozzle for sucking ₂ rises sucks full Shino bobbin M _1, M _2, pegs 4a, 4b are rotated in a direction unwinding the SaiMitsuru bobbin M _1, M ₂ (Fig. 3 (2)). Next, while rotating the full bobbins M ₁ and M ₂ , the Shino joint head 6 descends while continuing the suction (Fig. 3 (3)), and the Shino joint head 6 is sucked from the full bobbins M ₁ and M _2. Grasp the extending Shino R ₁ and R ₂ and swing them. At this time, since the suction is continued, the shin is cut downstream of the shin joint head 6 to form the shin end (3rd part).
Figure (4)). The Shinotsuji head 6 advances and grips the Shino end near the trumpet 2 upstream of the drafting section of the spinning machine, and superimposes it on Shino r ₁ and r ₂ of the small bobbin F ₂ and B ₂ , where the full bobbin The shino joint is completed by removing the shino end from the shino end and holding the shino r ₁ and r ₂ of the small bobbin F ₂ and B ₂ while the hanger 7
Divide a and 7b into full bobbins M ₁ and M ₂ and move them forward (Fig. 3 (5)). While raising the hangers 7a, 7b and returning the hinoki joint head 6 to its original position, the pegs 4a, 4b are moved forward to remove the small bobbins F ₂ , B ₂ (Fig. 3 (6)). In order to make a space for removing the small bobbins F ₂ and B ₂ from the spinning machine, the hangers 7a and 7b hold the full bobbins M ₁ and M ₂ as shown by the arrow in the upper layout of FIG. 3 (7). retreats away from each other, the pegs 4a, 4b is a Kodama bobbins F _2, B ₂ drops removed from the creel bobbin hangers of the spinning frame to rise. Kodama bobbins F _2, Shino r ₁ from B ₂ are down hanging, r ₂ is peg 4a, Kodama bobbins F _2, B ₂ wound assume by rotating the 4b (FIG. 3 (7)). The pegs 4a, 4b are retracted together with a space between them (Fig. 3 (8)), and the relative positions of the pegs 4a, 4b are rotated as shown by the arrow in the upper layout of Fig. 3 (9). Then move to the position just below the bobbin hanger on the spare rail. The pegs 4a, 4b are lifted to hang the small bobbins F ₂ , B ₂ on the corresponding bobbin hangers on the spare rail (Fig. 3 (10)), and then the hangers 7
Move a and 7b together with full bobbins M ₁ and M ₂ as shown in the upper layout of Fig. 3 (11), and lower hangers 7a and 7b to support full bobbins M ₁ and M ₂ on pegs 4a and 4b. Let Hanger
7a and 7b are retracted and contracted, while the Shino hanging plate (not shown) is moved along the locus shown in the lower side view of Fig. 3 (11) to move Shino R _{1 of} full bobbins M ₁ and M _2. , R ₂ on the roving guide, then return the Shino hanging plate to its original position. At this time, the full bobbins M ₁ and M ₂ are rotated in the unwinding direction by the pegs 4a and 4b (Fig. 3 (12)). The full bobbins M ₁ and M ₂ are moved by the pegs 4a and 4b so that the full bobbins M ₁ and M ₂ are aligned in a line in the vertical direction in the longitudinal direction of the spinning machine (Fig. 3 (13), and then the pegs 4a and 4b, 4b are advanced so as to widen the mutual space (Fig. 3 (14)), and the full bobbins 4a, 4b are suspended by the corresponding bobbin hangers of the creel by raising the pegs 4a, 4b, and then the pegs 4a. , 4b are returned to their original positions ((15) in FIG. 3), and the above work is repeated to replace half of the spinning machines.

FIG. 4 shows the working procedure of the fourth embodiment of the reshuffling method according to the present invention (FIGS. 4 (1) to 4 (6)). As can be seen by comparing FIG. 4 with FIG. 3, the fourth embodiment is carried out using the apparatus of the third embodiment, but the working procedure is different, and first, the small bobbins F ₂ and B ₂ are removed. The work begins by retracting the full bobbins M ₁ and M ₂ from the bobbin hanger of the spare rail and lowering them (Fig. 4 (3)). After the operation, the Shino hanging from the Kodama bobbins F ₂ and B ₂ is wound up (Fig. 4 (4)), and the Shining hanging plate is used to hook it onto the roving guide (Fig. 4 (5)). ), Suspend the full bobbins M ₁ and M ₂ on the bobbin hanger of the creel of the spinning machine and empty the bobbin.
F ₂ and B ₂ are suspended on the bobbin hanger of the spare creel (Fig. 4 (6)). Needless to say, the full bobbins M ₁ and M ₂ may be hung on the bobbin hanger and then the hanging operation may be performed, and the same applies to the above embodiments.

Next, the relationship between the diameter of the full bobbin supplied, the longitudinal pitch of the full bobbin, and the pitch of the creel of the spinning machine will be described with reference to FIGS. 5 (A) to 5 (C). As described above, by using the method of changing the thread according to the present embodiment, the full bobbin and the middle ball bobbin can be alternately mounted on the creel on the spinning machine one by one in front and rear, so that the conventionally known small bobbin in the front row can be mounted on the spare rail. A large full bobbin can be used as compared with the replacement method in which the full bobbin is replaced. Thus, when arranging the full bobbins larger than the creel pitch along the longitudinal direction of the spinning machine, it is preferable to arrange the full bobbins in a zigzag pattern as shown in FIGS. That is, as shown in FIG. 5A, 1> m when the full bobbin diameter is 1, the creel pitch is m, and the full bobbin longitudinal pitch is n, and when n = m, (A)
It may be staggered as shown in the figure, and when 1 <m and n = m, they are arranged linearly as shown in FIG. And n = m
In this case, after the B ₁ F ₁ Shino exchange is first performed, then the Shino exchange 10 may perform the Shino exchange to the position corresponding to B ₃ F ₃ , so the bobbin hanger of the spare rail may be fixed. However, when arranging l> m and n> m as shown in FIG. 5 (C), the carriage which travels on the spare rail is replaced after the shino exchange by the conveying means as disclosed in, for example, JP-A-60-67368. Every time 10 is run, the carriage (nm) of the spare rail is moved to make the next small bobbin B ₃ F _{3 correspond} to the next full bobbin M ₃ M ₄ and perform the shino exchange. When 1 <m and n = m as shown in FIG. 5 (B), it is meaningless to spin a full bobbin and a medium bobbin alternately during the first spinning as in the above embodiment. In such a case, full bobbins should be set on all bobbin hangers as usual, and then spun. At this time, B ₁ F ₁ , B ₂ F ₂ ...
... and a pair of small bobbins before and after should be sequentially exchanged.
At this time, if the full bobbins are arranged in a line as shown in FIG. 5B, the next small bobbin B ₂ F ₂ and the full bobbin M ₃ M ₄ will not correspond, so the Shino exchange 10 will be moved after the Shino exchange. Each time, the carriage of the spare rail that suspends the full bobbin is moved by the pitch m of the creel, or the spare rail is moved back and forth 2
The full bobbins may be arranged in rows so as to correspond to the pair of front and rear small bobbins, and the bobbins may be sequentially replaced.

〔The invention's effect〕

As described above, the present invention, when the pair of front and rear Shinobaki bobbins becomes a small bobbin, stops the Shino exchange machine running intermittently from one end to the other end of the machine base at a predetermined exchange work position, At the exchange work position, at least a pair of front and rear small bobbins are simultaneously removed from the creel by the Shino exchange, and then the Shino exchange moves the corresponding at least two full bobbins to the machine base to the machine base at the small bobbin removal position of the creel. At the same time, the shino exchange work is performed by suspending so that the ones in the front row of the creel and the left ones in the back row of the creel are performed at the same time. Even if at least two full bobbin Shino corresponding to the spare rail are connected to the bobbin Shino, it is possible to easily replace the Shino without tangling these Shino bobbins, resulting in a full bobbin. Easily to yarn end finding the Shinotan in a state of being positioned in front above the creel is quickly Shino piecing can result. In addition, since at least a pair of front and rear small bobbins, which are alternately positioned along the longitudinal direction of the machine base, are simultaneously replaced, a full bobbin larger than the creel pitch interval can be set, and the existing spinning frame with a small creel interval can be installed. Can use a large bobbin with a large diameter.

Further, according to the present invention, prior to the shino exchange, at least one pair of front and rear small bobbins are simultaneously spliced at the shino end of the corresponding full bobbin of the spare rail by the shino exchange, and then at least the front and rear pair after the shino splice is performed by the shino exchange. Since the small bobbin of is replaced at the same time as at least two full bobbins corresponding to the spare rail, at least a pair of front and rear small bobbins can be mechanically connected and replaced, and the replacement work is completely automated. There is an effect that can be done.

[Claims] 1. A spinning machine for exchanging a full bobbin in a single row suspended on a bobbin hanger on a spare rail provided in front of the creel and a bobbin suspended on two rows of bobbin hangers before and after the creel. In the Shino conversion method, when a pair of front and rear Shino winding bobbins become small bobbins, the Shino exchange that runs intermittently from one end to the other end of the machine base is stopped at a predetermined replacement work position, and the replacement work is performed. Position, remove at least a pair of front and rear small bobbins from the creel at the same time by the Shino exchange, and then move the corresponding at least two full bobbins on the spare rail to the machine base by Shino exchange at the small bobbin removal position of the creel. At the front row of the creel, the shino exchange work is performed by simultaneously suspending so that the left ones are located in the rear row of the creel respectively. Shino of actuation method in a spinning machine, characterized in that sequentially carried out in the replacement position towards. 2. A spinning machine for exchanging a full bobbin in a single row suspended on a bobbin hanger of a spare rail provided in front of the creel and a bobbin suspended on two bobbin hangers before and after the creel. In the Shino conversion method, when a pair of front and rear Shino winding bobbins become small bobbins, the Shino exchange that runs intermittently from one end to the other end of the machine base is stopped at a predetermined replacement work position, and the replacement work is performed. At the position, the Shino exchange machine simultaneously joins the Shino ends of the corresponding full bobbins of the spare rail to the Shino of the front and rear pair of small ball bobbins, and then the Shino exchange machine creels at least the front and rear pair of small ball bobbins after the Shino exchange machine. After removing them simultaneously from the machine, use the Shino exchange to move at least two corresponding full bobbins on the spare rail to the machine base at the creel small ball or empty bobbin removal position. The right one is hung on the front row of the creel, and the left one is hung on the rear row of the creel at the same time. A method for replacing a spinning machine that is performed sequentially at work positions.
