Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for changing the threads in a fine loom, and more specifically, bobbin hangers are installed in two rows in the front and back on the creel, and Shinomaki bobbins are suspended from the two rows of bobbin hangers in the front and back. The present invention relates to a method and apparatus for changing the front and rear rows of Shino-waki bobbins in a Kazu spinning machine that guides lees yarn from the Shino-waki bobbin to a drafting section and outputs paper.

Generally, the winding diameter of a full bobbin of a weaving tin bobbin attached to the creel of a spinning machine is larger than the spindle pitch of a fine loom.

Therefore, the Shinomaki bobbins are arranged in two rows in the combined longitudinal direction with an interval twice the spindle pitch, and a roving rod or roving guide is installed between the front and rear rows of bobbins to guide the roving from the Shinomaki bobbin. be done. However, the Shinomaki bobbin was suspended above the machine stand, which was higher than the worker's height.
Moreover, the weight of a full bobbin has become extremely large in recent years, and
It has started to exceed K9. Therefore, the work of replacing the wire on a Kazu paper spinning machine requires lifting a heavy bobbin up to the height of the user's height, making the work difficult. It is quite hard work to handle the same number of empty bobbins. In particular, ``In order to replace the bobbin at the back of the machine (back row bobbin), it is extremely difficult to remove the empty bobbin and install the full bobbin while avoiding obstacles such as roving guides. In addition, when changing the thread, in addition to removing the empty bobbin and installing a full bobbin, it is also necessary to cut the roving thread in progress, take out the roving end of the full bobbin, and attach the thread to the drafting section. After that, many troublesome operations such as thread splicing are required, but all of these operations are much more difficult to perform on the bobbin on the back side of the machine than on the bobbin in front of the combination (front row bobbin).The present invention The object of the present invention is to enable quick and easy exchange of empty bobbins and full bobbins and other replacement work.

According to the present invention, the above-mentioned object is achieved by providing a method and apparatus for automatically replacing the front row Shinumaki bobbin and the rear row Shinumaki bobbin.

That is, the above-mentioned object is achieved by making it necessary to perform the refilling work only on the front row bobbins. According to the present invention, the creel is provided with bobbin hangers in two rows, front and rear, and the rovings are guided from the respective Shino-waki bobbins suspended from the bobbin hangers to the drafting section to be graded, and the bobbin hangers in the front and rear rows are In a Kazu spinning machine that starts weaving with a medium-sized bobbin installed in one row of bobbin hangers and a full bobbin installed in the other row of bobbin hangers, the front row Shinomaki bobbin and the rear row Shinomaki bobbin are connected. When replacing the winding bobbin, grasp the pair of front and rear bobbin hangers that suspend the Shinomaki bobbin, pull out both bobbin hangers from the bobbin hanger holder, turn the bobbin hanger 1800 degrees in a horizontal plane, and remove both bobbin hangers. Swap the position of
Insert both bobbin hangers into the bobbin hanger holders on the opposite side from the one before replacing them, release the grip on the bobbin hangers, and complete the replacement of the front and rear pair of Shinomaki bobbins. It is characterized by going sequentially from one end of the pond to the other end of the pond.

According to the present invention, the Shinomaki bobbin exchange device has a pair of grips that can grip the front and rear bobbin hangers, a support member that slidably supports the grips, and two approximately elliptical cam grooves, A grooved cam that engages a cam follower of the grip in the cam groove to control the gripping and releasing movement of the bobbin hanger and the approaching and separating movements of both grips, a grooved cam drive mechanism that rotates the grooved cam, and a grooved cam drive mechanism that rotates the grooved cam. A Shino shunting machine, which includes a clutch mechanism that engages and disengages from a cam and rotates the support member integrally with the grooved cam, is movable in the longitudinal direction of the frame of the spinning machine.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

An embodiment of the apparatus of the present invention is illustrated in FIGS. 1-14.

As shown in Fig. 1, a plurality of creel pillars 2 are disposed at appropriate intervals in the longitudinal direction of the machine in the center of the assembly 1 of the paper machine, and drafters on each side of the paper machine are installed. Above part 17,
Two rails 7 and 8 supported by the creel pillar 2
Two rows of bobbin hangers 14, front and rear, are supported. In the conventional case, since weaving is started with full bobbins loaded on both the front and rear bobbin hangers, the front and rear bobbins become empty at the same time. Therefore, it was necessary to replace the two rows of bobbins at the same time. On the other hand, when using the Shinomaki bobbin changing device of the present invention, among the two rows of bobbin hangers, "one row of bobbin hangers is loaded with a medium-sized bobbin, and the other row of bobbin hangers is loaded with a medium-sized bobbin." Load a full bobbin and start spinning.

Therefore, since the emptying times of the front row bobbins and the rear row bobbins are different, it is possible to replace the bobbins one row at a time. If you try to change the bobbin in the back row while it is in that position, it will be difficult to do as described above, so before or after replacing the spare full bobbin with the empty bobbin (or small bobbin), The Shinomaki bobbin in the front row and the Shinomaki bobbin in the rear row are replaced by the Shinomaki bobbin replacement device of the invention. That is,
If you load a medium bobbin into the bobbin hanger in the rear row and a full bobbin into the bobbin hanger in the front row and start the grade, the following steps will be taken: ``The rear row bobbin will be empty first, so the positions of the front row bobbin and the rear row bobbin will be swapped.'' After that, perform the Shinokae work.
On the other hand, when starting weaving with a full bobbin loaded on the rear row bobbin hanger and a medium bobbin loaded on the front row bobbin hanger, after replacing the spare full bobbin with the empty or small bobbin in the front row, Swap the positions of the front row bobbin and back row bobbin.

By doing this, it is only necessary to always replace the empty or small bobbin located in the front row with the spare full bobbin when changing the bobbin.

As mentioned above, you can load a full bobbin into either the front or rear bobbin hanger, but it is better to load a full bobbin into the front row bobbin hanger and when it becomes a medium bobbin, replace it with the small bobbin in the rear row, which will allow the bobbin to be replaced at a narrower interval. This is preferable because it can be carried out smoothly.

In the embodiment shown in FIG. 1, the rear row bobbin hanger 14'
This is a case where a medium bobbin is set, a full bobbin is set on the bobbin hanger 14 in the front row, and weaving is started.

In Fig. 1, the bobbin in the rear row is the empty bobbin 15C (in the following explanation, the bobbin, including the small bobbin with roving still remaining on the bobbin, will be referred to as an empty bobbin), and the bobbin in the front row is the medium bobbin 15B. This shows a state in which Shino Kasai is about to start. In the embodiment shown in FIG. 1, a Shino switching machine 10 of the present invention for replacing bobbins in the front and rear rows, and a spare full bobbin 15A (or empty bobbin 15C) are installed on each side of the spinning machine.
A bobbin hanger 18A for hanging the bobbin and a Shino exchange machine 64 for exchanging the empty bobbin 15C in the front row with the spare full bobbin 15A are provided.

The Shino shunting machine 10 and the Shino shunting machine 64 may be installed as dedicated machines in each spinning machine, but similar to the conventionally known self-propelled auto doffer (auto doffer for fine paper tube yarns), multiple machines may be installed. It is preferable to share it with spinning machines. The bobbin hanger 18A for full and empty bobbins is supported by the spare rail 4 supported by the creel pillar 2 above the front row bobbin hanger. The Shino shunting machine 10 has bobbin hangers 14 in the front and rear rows.
It is placed above the machine and moves in the longitudinal direction of the machine to sequentially replace the front and rear rows of bobbins. The Shinogatari≠Ken machine 64 runs along the spindle row at the front of the machine, and the empty bobbin 15 in the front row
C and the spare full bobbin 15A are replaced one after another. DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure and operation of the knee replacement device of the present invention will be explained in detail below with reference to the drawings. As shown in FIG. 1, in this embodiment, the creel pillar 2 is extended upwards compared to a normal creel pillar.

A spare rail bracket 3 is fixed to the upper part of the creel pillar 2 and extends to both sides in the machine width direction. The tips of the spare rail bracket 3 protrude above the path in front of the loom, and spare rails 4 extending over the entire length of the loom are attached to both tips of the bracket 3, respectively. The preliminary rail 4 is a hollow columnar body with an open bottom, as shown in its cross-sectional shape in FIG. Both ends of the spare rail 4 in the longitudinal direction are closed, and from the closed end, the bobbin hanger 18
A bobbin carriage 5 with A is inserted. The bobbin carriage 5 will be detailed later. A bracket 6 is attached to the spare rail bracket 3 at a position inside the spare rail 4.

A front rail 7 extending in the longitudinal direction of the machine is fixed to the lower end of the bracket 6. On the other hand, a rear rail 8 is fixed to a bracket 9 attached to the middle portion of the creel pillar 2.
The space above the front row rail 7 and the rear row rail 8, regulated by the bracket 3, bracket 6, and creel pillar 2, becomes a passage 11 for the Shino shunting machine 10 to travel. As shown in FIG. 3, a bobbin hanger holder 12 and a spring catch 13 are attached to the front row rail 7 and the back row rail 8 at an interval P (see FIG. 8) that is twice the spindle gauge of the spinning machine. The bobbin hanger holder 12 and spring catch 13 of the rail 7 are arranged opposite to the bobbin hanger holder 12 and spring catch 13 of the rear rail 8.

As shown in FIGS. 3 and 4, a spring catch 13 is provided on the lower surface of the bobbin hanger holder 12, and the bobbin hanger holder 12 and the spring catch 13 each have a closing portion 12a and an opening portion 13a. Both the closing parts 12a and 13a are in an aligned state. Further, the closing portions 12a, 13a on the front rail side and the openings of the bobbin hanger holder and spring catch on the rear rail side face each other. The opening 12a of the bobbin hanger holder 12 is connected to an engagement groove 14 provided at the top of the bobbin hanger 14.
On the other hand, the opening part 13a of the spring catch 13 can be elastically engaged with a step part 14b provided below the engagement groove 14a of the bobbin hanger 14. Therefore, the bobbin hanger 1 is inserted into both the openings 12a and 13a.
4, the bobbin hanger 14 connects to the bobbin hanger holder 12 and the spring catch 13.
It is removably attached to and suspended in a stable state due to its elastic force. Note that instead of the spring catch 13, a magnet, for example, a magnet, is attached to the upper surface 12b of the bobbin hanger holder 14.
In addition to providing rubber, a magnetic material such as an iron plate may be provided in the portion of the bobbin hanger 14 that contacts the upper surface 12b to ensure that the bobbin hanger 14 is held by magnetic force. At the top of the bobbin hanger 14, another engagement groove 14c is provided above the engagement groove 14a.

The engagement groove 14c is formed in the bobbin hanger holder 12 when the bobbin hanger 14 is suspended on the bobbin hanger holder 12.
It protrudes above the upper surface 12a and engages with grippers 52 and 53 (see FIG. 12) of the Shino shunter 10, as described later. Referring again to FIG. 1, it is assumed that the Shinonaki bobbins 15 that are first suspended by the bobbin hanger 14 have different winding diameters in the front row and in the rear row. For example, the front row bobbin hanger 14 is loaded with a full bobbin, and the rear row bobbin hanger 14 is loaded with a medium bobbin. A lees guide 16 is disposed below the bobbin hanger 14 and at a position midway between the suspended front and rear row bobbins.

This hammer thread guide 16 is attached to the creel pillar 2 by a support village 16a. Figure 5 shows the matching thread guide 16.
In this embodiment, the roving guide is annular and has a thread guiding hole 16b. FIG. 6 shows another embodiment of the roving guide 16. In this embodiment, the roving guide has a partially open C-shape and has a thread guiding hole 160 and a thread guiding groove 16c. . In Figure 1, bobbins 15 in the front and rear rows
Each roving pulled out from the thread guide hole 16b of the roving guide 16
After passing through the paper, the paper is supplied one by one to the drafting section 17, where the paper is output. A movable bobbin carriage 5 equipped with a bobbin hanger 18A is suspended from spare rails 4 arranged on both sides of the creel pillar 2, respectively.

As shown in FIGS. 7 and 8, in the bobbin carriage 5, a bobbin hanger 18A for one row of creels and one or several spare bobbin hangers 18B for replacement of threads are arranged at the same bobbin interval P of the creel. Bobbin carriage bar 19 at intervals
installed on. A vertical guide roller 20, a horizontal guide roller 21, and a stop pin 22 are provided on the upper surface of the bobbin carrier 19. As shown in FIG.
It can be placed on top of a and can be moved on top of it. The horizontal guide roller 21 can engage with the vertical surface 4b of the preliminary rail 4. The stop pin 22 is attached to one end of the bobbin carriage 19 as shown in FIGS. 7 and 8, and when the bobbin carriage 5 is inserted into the spare rail 4, a spring catch 23 attached to one end of the spare rail 4 is attached. The stop pin 22 is inserted into and held elastically. This positions the bobbin carriage bar 19, that is, the bobbin carriage 5. In this positioning state,
As shown in FIG. 8, the position of the bobbin hanger 18A is shifted from the creel bobbin by a half pitch (P/2). A full bobbin 15A must be suspended from the bobbin hanger 18A of the bobbin carriage before the start of replacement, but there are two ways to do this.

One is to suspend the bobbin carriage 5 on the spare rail 4 while leaving the bobbin hanger 18A empty, and then attach a full bobbin 15A to the bobbin hanger 18A.

Another method is to attach the full bobbin 15A to the bobbin hanger 18A in advance before suspending the bobbin carriage 5 on the spare rail 4.
and insert the bobbin carriage 5 into the spare rail 4 by means of suitable transport means. In either case, the full bobbin 15A is not hung on the bobbin hanger 18B for replacement, which is disposed at one end of the bobbin carrier 19, and is left empty. As shown in FIG. 9, a predetermined number of spinning machines 1 having creels configured as described above are arranged side by side with passages of appropriate width between the machines to form a spinning machine 24.

The out-end side of this paper pulp machine group 24 (the right side in Fig. 9)
Two rails 25 for the transport vehicle 26 for the Shino shunting machine are installed above the end of the machine. The transport vehicle 26 is equipped with two symmetrical Shino shunting machines 10, 10 in order to simultaneously replace the front and rear row bobbins of the fine loom on both sides of the fine loom.
Then, by reciprocating on the rails 25, the shinoki shunters 10, 10 are joined to the outer ends of the front and rear rows of wheels 7, 8 on both sides of the kasu loom 1. As shown in FIG. 1, the two Shino shunting machines 10 running along the front and rear rows of wheels 7 and 8 on each side of the fine loom are symmetrical to each other and have the same structure. , one Shino shunting machine 10 (the left Shino shunting machine in Fig. 1) will be explained with reference to Figs. 10 and 11.

Left and right driving wheels 27 and driven wheels 28 are attached to the main body 29 of the Shino shunting machine 10.

The drive wheel 27 is fixed to an axle 36, and a gear 37 built into the main body 29 is similarly fixed to the axle 36.
The gear 37 meshes with a gear 35 fixed to an output shaft 34 of a brake-equipped traveling motor 33 disposed within the main body 29. The left and right driving wheels 27 and driven wheels 28 are movably mounted on the front rail 7 and the rear rail 8 of the paper mill 1. That is, the main body 29 of the Shino shunting machine is movable on the front and rear rails 7 and 8. A control box 30 is mounted on the top surface of the main body 29.
Two current collectors 31 are provided above 0 in a protruding manner. These two collectors 31 contact the trolley wires 32 wired above the creel when the Shino shunting machine 10 is placed on the front and rear rows of the creel 7, 8, and the Shino shunting machine 10
Power is supplied to the The traveling motor 33 is capable of forward and reverse rotation, and when the motor 33 rotates, the drive wheels 27 are driven via the gears 35 and 37. As a result, the Shino shunting machine 10 reciprocates on the front and rear rails 7 and 8. In addition, the Shino shunting machine 1 is equipped with a photoelectric stop position detector 38, and each time the stop position detector 38 detects the detection piece 39 or the bobbin hanger holder 12 while the Shino shunting machine 10 is running, A detection signal is issued, and the traveling motor 33 is suddenly stopped in accordance with the command of this signal, thereby reliably stopping the Shino shunting machine 10 at a predetermined position. A main shaft 41 perpendicular to a boss portion 40a of a bracket 40 fixed to the inner wall of the main body 29 is rotatably inserted with iron, and a clutch 42 is slidably coupled with a key to an intermediate portion of the main shaft 41. One end of a shift lever 43 is engaged with this clutch 42, and this shift lever 43 is constantly biased by a spring 44 so as to raise the clutch 42. The other end of the shift lever 43 is connected to a clutch switching solenoid 45.
When energized, shift bar 43 causes clutch 42 to move downwardly. When the clutch 42 is raised upward, the upper teeth 42a of the clutch 42 mesh with the teeth 40b formed at the lower end of the boss portion 40a of the bracket 40, thereby regulating the rotation of the main shaft 41. Further, when the clutch 42 is slid downward by the excitation of the solenoid 45, the lower teeth 42b of the clutch 42
7 meshes with clutch teeth 48 integrally provided on the upper surface of the clutch. A grooved cam 46 is fitted onto the main shaft 41 so as to be freely rotatable, and two cam grooves 46a and 46b are formed on the lower surface of the grooved cam 46.

The above-mentioned gear 47 and clutch teeth 48 are integrally connected to the upper side of the grooved cam 46. The gear 47 meshes with a gear 50 attached to the output shaft of a drive motor 49 that is capable of forward and reverse rotation. Therefore, when the motor 49 rotates, the grooved cam 46 is driven via the gear 50 and the gear 47 and rotates in a horizontal plane. . As shown in FIG. 12, two cam grooves 46a and 46b formed on the lower surface of the grooved cam 46 have substantially similar gourd shapes and are arranged concentrically.

Two pairs of grippers 52, 53 are provided in the cam grooves 46a, 46b.
Cam followers 51 provided at the top of each engage. Each pair of grippers 52, 53 is connected to two guide rods 54a held by a grip holder 54 keyed to the main shaft 41.
, 54b (FIG. 10). The lower ends of the left and right grippers 52, 53 have claw portions 52a, 5.
3a, and these claw portions 52a and 53a can be engaged with the engagement grooves 14c at the tops of the front and rear row bobbin hangers 14, respectively. As shown in FIG. 12, when the grooved cam 46 rotates relative to the main shaft 41, each pair of grippers 52 and 46b engage with the cam grooves 46a and 46b. It serves to narrow or widen the distance between the cam followers 51 of 53, and to move the bobbin hangers in the front and rear rows toward and away from each other.

As a result, each pair of grippers 52, 53 grips the bobbin hanger 14 in the front row or the rear row, and approaches and separates from each other, or releases the bobbin hanger 14. That is, when the main shaft 41 is stationary and the grooved cam 46 rotates, the gripper 52 has its cam follower 51 engaged with the inner cam groove 46a.
Guide rod 54a5 according to the shape of inner cam groove 46a

a, 54b. As described above, the main shaft 41 remains stationary and only the grooved cam 46 rotates when the upper teeth 42a of the clutch 42 and the teeth 4Qb formed on the boss portion 40a are engaged, that is, when the solenoid 45 is excited. This is the case where it has not been done. On the contrary, when the solenoid 45 is energized, the lower teeth 42b of the clutch 42 and the clutch teeth 48 are engaged, and the clutch 42 and the main shaft 46 are keyed together, so the gear 47 When the grooved cam 46 and the main shaft 41 rotate, the grooved cam 46 and the main shaft 41 rotate in synchronization. Since the guide rods 54a and 54b also rotate together with the main shaft 41, no relative movement occurs between the grooved cam turtle 6 and the grippers 52 and 53. Switching of the clutch 42 mentioned above is controlled by a plurality of switches.

That is, as shown in FIG. 10 and FIG. 12 la, a switching switch dog 56 and an operation completion detection switch dog 57 are fixed to the upper surface of the gear 47 connected to the grooved cam 46, and the switch dogs 56 and 57 correspond to each other. Limit switches 58 and 59 are arranged at fixed positions on the outside. The clutch switching solenoid 45 is activated by commands from these limit switches 58 and 59. Further, when the limit switch 59 for detecting completion of operation is activated, the traveling motor 33 is electrically connected so as to be restarted. In FIG. 12, la, 2a, 3a, 4a are switch dogs 56, 57 and IJ mitt switches 58, 59.

At the first position, that is, the start position 1, each pair of grippers 52, 53 is in an open state, as shown by lc, and the respective claws 52a, 53a of the grippers 52, 53 are in an open state.
is not engaged with the bobbin hanger 14. The front row and rear row bobbin hangers 14 are suspended by bobbin hanger holders 12 and spring catches 13 attached to the front row rail 7 and the rear row rail 8, respectively. At the start position, the operation completion switch dog 57 faces the operation completion detection limit switch 59, and when the motor 49 starts rotating, the operation completion switch dog 5 again faces the operation completion detection limit switch 59.
The rotation of the gear 47 and the grooved cam 46 continues until the operation completion detection IJ mitt switch 59 is activated. That is, when the grooved cam 46 rotates 360 degrees, it stops. The state at the second position when rotated 90 degrees from the starting position is 2a.

In this position, the front and rear row bobbin hangers 14 are firmly gripped by the claws 52a and 53a of each pair of grippers 52953, and are pulled out from the respective closing portions 12a and 13a of the bobbin hanger holder 12 and spring catch 13, so that the front row bobbin hangers 14 and back row bobbin hanger 1
4 is brought closer. When the second position is reached, the changeover switch dog 56 contacts the limit switch 58, so that the solenoid 45 is energized and the lower tooth 42b of the clutch 42 engages with the clutch tooth 48 (FIG. 12, 2c).

The state at the third position when rotated by 0° is shown in FIG. 12, 3a?
3b and 3c.

During 180° from the second position to the third position, the switch dog 56 continues to contact the limit switch 58, so the solenoid 45 is maintained in an energized state, and therefore the lower clutch tooth 42b and the clutch tooth 48 are They remain engaged. During this 180° rotation, the main shaft 41 and the gripper holder 54 rotate together with the grooved cam 46. As a result, the positions of the front and rear row bobbin hangers 14 that suspend the bobbin are switched. 3c shows the state at the time of replacement.

During this exchange, the bobbins are exchanged while the two pairs of grippers are close to each other in the center, as in the case of the second position, so bobbins can be exchanged even in a narrow space, and adjacent bobbins can be exchanged. I won't come into contact with you. The state at the fourth position when rotated 360° from the starting position is shown in FIGS. 4a, 4b, and 4c.

Between the third and fourth positions, the switch dog 5
6 does not contact the limit switch 58, the solenoid 45 is demagnetized, the clutch 42 is raised again, and the teeth 42a of the upper example of the clutch 42 mesh with the teeth 40b of the boss portion. Therefore, while the grooved cam 46 rotates from the third position to the fourth position, the main shaft 41 remains stationary. Each gripper 52, 53 is therefore slid along the guide rod' according to the cam grooves 46a, 46b. In this case, the first
Contrary to when moving from one position to the second position, the distance between the pair of grippers 52, 53 increases and each gripper 5
2 and 53 move outward and away from each other.
As a result, the bobbin hanger 14, which had been gripped by the grippers 52 and 53, is inserted into the openings 12a and 13a of the bobbin hanger holder 12 and the spring catch 13, and is gripped by the grippers 52 and 53.
The claw portions 52a and 53a of 53 are separated from the engagement groove 14c at the top of the bobbin hanger 14 to release the bobbin hanger 14. Then, the switch dog 57 comes into contact with the operation completion detection limit switch 59, so the rotation of the motor 49 is stopped and the travel motor 33 is restarted. As mentioned above, the front and rear rows of the bobbin hanger 14 are exchanged by the Shino exchange machine, but this mainly involves two mechanisms:
That is, the bobbin hanger 14 is connected to the bobbin hanger holder 12.
This is accomplished by a mechanism for attaching and detaching the spring catch 13 and a mechanism for rotating the bobbin hanger 14 by 180 degrees.

In the embodiment described above, the two cam grooves 46a, 46b, the two pairs of grippers 52, 53 having the cam followers 51 that engage with these cam grooves, and the guide rod 54a that slidably support the grippers cooperate with each other. The bobbin hanger 14 is attached and detached by operation. In other words, each of the above elements constitutes the bobbin hanger attachment/detachment mechanism 55. Also groove cam 4
The grippers 52 and 53 are moved by the cooperative work of the clutch teeth 48 integrally connected to the clutch 6, the clutch 42 meshing with the clutch teeth, the main shaft 41 keyed to the clutch 42, and the gripper holder 54 keyed to the main shaft 41. The respective elements constitute a turning mechanism 60. Shino Switching Machine 1 When switching the front and back rows of the bobbin hangers 14, if you turn the bobbin hangers in the same direction as the previous rotation, that is, you will rotate the bobbin hangers twice in the same direction. When the yarn is turned, the two rovings connected to the drafting section 17 from the front and rear Shino-waki bobbins become intertwined with each other, and if the grading is continued in this state, thread breakage will occur.

In order to prevent this, the direction of rotation of the bobbin hanger may be reversed each time the wires are replaced. For this purpose, as shown in FIG. 10 and FIG.
, 618 are the lower front row and rear row bobbin hangers 14
The top of one bobbin hanger (the left bobbin hanger in FIG. 13) is connected to the other bobbin hanger among the bobbin hangers 14 that are arranged opposite to each other and that are located in the front and rear rows at the most extreme position on the approach side of the Shino shunting machine. 14 (the difference between the two is indicated by h in FIG. 13), and the upper glue mitt switch 61A or 61B is activated at the higher top. Therefore, the positions of the bobbin hangers having high tops are switched between the front row and the rear row every time the threads are replaced, so the limit switches 61A and 61B are activated alternately every time the threads are replaced. The motor 49 that drives the gear 47 of the grooved cam 46 rotates forward or reverse in response to commands from the limit switches 61A, 61B, and as a result, the direction of rotation of the rotation mechanism 60 is reversed. As shown in FIG. 14, drafting sections 17, 17 located on the left and right sides of the virtual plane S-S connecting the axes of the front and rear bobbins.
When braided yarn is supplied from the front row and rear row Shinomaki bobbins 15, each Shinomaki bobbin is placed on the side where the drafting section 17 to which the roving drawn from the bobbin is located is located, that is, the virtual 1 on the right or left side with respect to the plane S-S
It rotates alternately forward and reverse by 800 degrees. 14th
In the example shown in the figure, the medium bobbin 15B in the front row passes through the left side of the roving guide 16, and the empty bobbin 15C in the rear row passes through the right side of the roving guide 16 and is replaced. Hereinafter, an example of a method for automatically replacing Shino-maki bobbins using the above-mentioned Shino-switching machine 10 will be described.

Prior to the change of paper grain, while the paper mill 1 is in operation, the bobbin carriage 5 with full bobbins 15A for one creel row suspended from the bobbin hanger 18A is inserted into the spare rails 4 on both sides of the creel via an appropriate conveyance means. As shown in FIGS. 8 and 14, each droplet pobbin 15A is located at an intermediate position (P
Position it so that it is in 2). A transport car 26 for a Shino shunter is connected to the out-end side of the spinning frame 1 to which the spare full bobbin 15A is supplied. Thereafter, as shown in FIG. 1, when the bobbins in the rear row become medium-sized bobbins and the bobbins in the front row become medium-sized, the left and right Shino shunting machines 10 mounted on the Shino shunting machine carrier 26 are creeled. The vehicle is moved onto the front and rear rails 7 and 8 on both sides of the vehicle, and is launched into the left and right aisles 11 from the out-end side toward the gear end. When the Shino shunter 10 starts from the out-end side and the limit switches 61A and 61B attached to the front of the main body 29 reach above the first bobbin hanger 14 on the entry side, one limit is set as shown in FIG. Bobbin hanger 14 with switch down
The rotating direction of the rotating mechanism 60 is electrically memorized in advance.

When the Shino shunter 10 moves further forward and the stop position detector 38 detects the detection piece 39 disposed in front of the first bobbin hanger 14 as shown in FIG. 10, this command causes the travel motor 33 to stop. , the left and right pair of grippers 52 and 53 of the attachment/detachment mechanism 55 are the first bobbin hanger 14 in the front and rear rows,
The first Shino exchange position corresponding to 14 (Fig. 10,
(See FIG. 11), the Shino shunting machine 10 stops. Shino shunting machine 1
0 stops, the motor 49 that drives the attachment/detachment mechanism 55 is activated in response to the detection command from the stop position detector 38. As described above with reference to FIG. 12, the attachment/detachment mechanism 55
During one rotation of the grooved cam 46 by the cooperative work of the turning mechanism 60, the front row medium bobbin 158 and the rear row small ball bobbin 15 are rotated.
The position of C is swapped, and the bobbin hanger 14 that suspends the medium bobbin 158 is supported by the bobbin hanger holder 12 and spring catch 13 in the rear row, while the bobbin hanger 14 that suspends the small bobbin 15C is supported by the bobbin hanger holder in the front row. 12 and a spring catch 13. In order to exchange the front and rear bobbins in this manner, as explained above with reference to FIG. Even if the rovings are threaded and each roving is supplied to the drafting section 17, the rovings will not become entangled and no roving breakage will occur. Therefore, the replacement of the front and rear row bobbins by the Shino shunter 10' can be carried out while the shino paper machine 1 is in operation.
Alternatively, it can also be carried out in the camphor stand of the papermaking machine. Paper paste machine 1
By performing the shinoki replacement work during the operation of the loom, it is possible to shorten the time that the kasu loom is on standby for the shino replacement.
When the grooved cam 46 rotates once, the limit switch 59 is activated by the switch dog 57, the drive motor 49 is stopped by the command of the limit switch 59, the travel motor 33 is restarted, and the left and right knee replacement machines 10 are activated. will move towards the next Shino replacement level.

As shown in FIG. 4, the bobbin hanger holder 12 of the rear bobbin hanger 14 has been replaced with the stop position detector 38.
Each time it is detected, the machine stops at the next Shino exchange position, and the front row medium bobbin 15B and the rear row small bobbin 15C are exchanged in the same order. Knee change machine 1 From the out end side to the gear end side, the bobbin is changed forward and backward for 2 spindles at a time, and after the change for one row of creels is completed, it runs in the opposite direction and moves to the out end side. The vehicle returns to the Shino shunting machine transport vehicle 26, which is waiting there. As described above, when the exchange of the medium bobbin 15B and the small bobbin 15C on both sides of the creel is completed and the left and right Shino exchange machines return to the carrier car 26 that they have, the appropriate At this timing, the transport vehicle 63 for the Shino exchange machine is joined.Then, the left and right Shino exchange machine carriers 64 mounted thereon are started along the front of the spinning machine 1 from the end side to the out end side.Then, the front row Empty bobbin 15C and spare full bobbin 15A
The exchange is performed sequentially from the gear end side to the out end side. At this time, the empty bobbin 15C transferred from the front row bobbin hanger 14 of the creel to the bobbin hanger 18A of the spare rail 4 is actually a small bobbin 25C with a small amount of roving remaining, and by the transfer, the empty bobbin 15C is transferred to the bobbin hanger 18A of the spare rail 4. The roving is cut. The bobbin suspended on the spare rail becomes a remaining thread bobbin. Before the cut lees end reaches the trumpet of the drafting section 17, a replacement staff member pulls out the roving from the full bobbin in the front row of the creel and inserts the roving end into the trumpet of the drafting section 17. Shino-tsugi is performed sequentially. After completing the exchange of bobbins for one row of creels, the left and right Shino exchange machines 64 move in the opposite direction and wait on the end side when the Shino replacement staff completes the Shino joint. Return to the transport vehicle 63 for the Shino exchanger.

In the above explanation, the full bobbin 1 suspended on the spare rail 4 is
5A was supplied before replacing the bobbins in the front and rear rows, but it may be performed before replacing the bobbins in the rear row before supplying the full bobbin 15A.

In addition, it was explained that the front row bobbin and full bobbin replacement should be started after the front and rear row bobbin replacement has been completed for all stirrups, but the Shino exchange machine 64 is connected to the Shino exchange machine 10 from both directions. It is also possible to allow the Shino shunting machine 10 to enter and perform the work following the Shino shunting machine 10. Furthermore, in the above embodiment, it was explained that the full bobbin 15A is loaded on the front row bobbin hanger 14, and the medium bobbin 15B is loaded on the rear row bobbin hanger 14 to start bushing. 14
Place the medium bobbin 15B on the back row bobbin hanger 1.
4, a full bobbin 15A may be loaded and weaving may be started.

In that case, the Shinomaki bobbin in the front row becomes an empty (small bobbin) first, so after replacing the empty bobbin 15C in the front row with the spare full bobbin 15A and performing the Shino splicing, From this, the full bobbin 15A in the front row and the medium bobbin 25B in the back row are replaced. In the above, it has been explained that the empty bobbin 15C and the full bobbin 15A are exchanged automatically by the Shino exchanger 14, but according to the method and apparatus of the present invention, the empty bobbin 15C in the front row and the spare bobbin 15A can be exchanged. Therefore, the empty bobbin 15C and the full bobbin 15A can be easily and quickly replaced manually.

Further, the full bobbin 15A to be replaced does not necessarily need to be suspended from the spare rail 4, but may be prepared in advance on a creel shelf or a transport vehicle. According to the invention,
By making the winding diameter of the Shinomaki bobbin, which is loaded on the creel at the start of paper output, different between the front row bobbin and the rear row bobbin, only one row of the front row or rear row bobbin will always have small balls, and the other rows will have small balls. The bobbin is made to be a medium ball at that point.

If the bobbins in the front and rear rows are swapped with medium and small bobbins, they will not interfere with the adjacent bobbins, making it easier to swap in space. According to the present invention, since the bobbins in the front row and the bobbins in the rear row are replaced together with the bobbin hanger, the bobbins can be replaced automatically without causing breakage of the roving even during paper output.

Further, according to the present invention, since the small bobbin to be replaced with the spare full bobbin is always positioned in the front row of the creel before the replacement is performed, it is easy to replace the full bobbin with the small bobbin.

Therefore, it can be performed easily and quickly even by hand. Furthermore, since only the front row bobbin is replaced with a full bobbin, automation is easy.
