Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention enables spinning of two or more types of yarn by arranging a large number of spinning machines in parallel, and also provides a method of simultaneously changing yarns. The present invention relates to a method for starting a spinning process in a spinning process.

(Prior Art) In recent years, labor saving has progressed in textile mills, and in many cases the automation of each process has gone one step further to include automation of connections and conveyance between each process.

In addition, in recent years, there has been a trend toward high-mix, low-volume production, and it has been proposed to operate the spinning machines in such a way that they spin multiple types of yarn instead of all spinning machines spinning the same type of yarn. It has been implemented. For example, the special public service announced on September 24, 1980,
5-36731, as shown in FIG.
, c to make a total of three groups, and one spare roving frame and one spinning frame d are installed, and each roving frame A, B, C, D and spinning frame a, b, c, d are connected to each other. The roving machines 1111A, B, and C are connected by a rail 61 and the Manshinomaki doffed by each roving machine A, B, and C are suspended from a pallet 62.
The spinning machines a and b are stored on the rails 61 by a transport vehicle 63 as necessary.

It is transported to the position corresponding to C, and at the same position, after being used in the spinning machine, the empty Shinomaki and Manshinomaki are replaced by hand.
A method has been proposed in which when all the full rolls on the pallet 62 are replaced with empty rolls, the rolls are again transported to the roving machines A, B, and C by the transport vehicle 63. However, this method uses spinning machines a and b.

Instead of replacing the Shinomaki used in C all at once, the weights that require Shino replacement occur randomly, and the worker hangs the empty Shinomaki of the weights that require Shino replacement on the pallet 62. Since this is a so-called preliminary roving changing method in which the manshin windings are replaced at any time, the burden of changing the rovings is extremely heavy on the operator. Furthermore, in order to increase the operating efficiency of spinning frame frames, spinning frame frames are generally operated 24 hours a day, or in nearly 24-hour operation, so that replacement work is required even late at night.

However, when working late at night, the operator's judgment becomes clouded, and the change of weights that require change cannot be carried out smoothly, resulting in a reduction in the operating efficiency of the machine.

In order to reduce the burden on the worker in changing the threads, the spinning machine creel is constructed with a conveyor magazine row in which the threads are hung, and when the threads of the spinning machine become empty, the empty threads (residual yarn bobbin) are hung up. Although there is a method for simultaneously replacing the lowered transport magazines and the transport magazine row from which the fully loaded rolls are suspended, it is impossible to apply the above method to this method. This is because the number of Manshin-maki used on a spinning frame is generally greater than the number doffed on a single Rover frame, so the Manshin-Maki doffed by a Rover is placed in the position of the Rover. If it is stored and transported to the spinning frame frame at the time of changing the frame, the number of spindles required by the spinning frame will not be sufficient.

(Problems to be Solved by the Invention) The present invention solves the problem of the conventional method for changing the pre-shin winding, which requires manpower to change the thread, and it is possible to solve the problem of the above-mentioned conventional method for changing the pre-shin winding. This paper proposes a new method that can reliably perform all-in-one replacement.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, each spinning machine frame in a group of spinning machines that spins two or more types of yarns has a simultaneous spin change system. We are hiring. Further, downstream of the spinning frame group, there is provided a blank winding magazine reserve section for accommodating a conveyance magazine row in which empty windings are suspended, which are automatically carried out from the spinning machine at the time of spinning change, and upstream is a blank winding magazine reserve section for accommodating a conveyance magazine row in which empty windings are hung, which are automatically carried out from the spinning machine at the time of spinning change. A Mitsushi-maki magazine reserve section is provided to store a transport magazine row in which the same type of Mitsshin-maki is suspended as needed for replacement of Shino. Further, a confirmation means for checking whether or not there is a space in the blank roll magazine reserve section for accommodating a row of blank roll transport magazines, and a confirmation means for suspending the required variety of Manshin rolls in the Manshin roll magazine reserve section. A means for confirming whether or not there is a transport magazine row is provided, and at the time of replacement, the replacement operation can be started based on confirmation of the existence of the space and the transport magazine row by the two means.

(Function) A group of spinning machines to which this invention is applied spins two or more types of yarn, and each spinning machine creel suspends the Shinomaki.
It consists of a row of transport magazines that hang blank rolls. At the time of refilling, the row of transport magazines with suspended empty rolls are carried out to the empty roll magazine reserve section located downstream of the spinning machine group. A transfer magazine row waits with the amount of Mitsshinomaki of the same type required for one Shino change suspended from the Mitsshinomaki magazine reserve section located upstream of the spinning machine group. is carried into the spinning machine frame.Then, when the spinning frame is used in the spinning machine frame and becomes empty and needs to be replaced, the operator presses the switch to start the spinning machine. If it is inserted, it is confirmed whether or not there is space in the empty magazine reserve section to accommodate the conveyance magazine row to be carried out from the spinning machine, and the requested type of Mitsushino is placed in the empty magazine reserve section. It is confirmed whether there is a transport magazine row with the required number of volumes suspended, and it is confirmed that there is a storage space in the empty volume magazine reserve section and that the required transport magazine row exists in the full volume magazine reserve section. After that, the changeover operation starts for the first time.

Next, the operation of the apparatus configured as described above will be explained. 2
Rover frame RF1. RF2 each spins different types of yarn, and in the first group of spinning machines, both sets of spinning machines RF1. Spinning is performed using different varieties of Manshinomaki 7 doffed from RF2. In addition, spinning machine group 1 is spinning machine 1 that spins different types of spinning machines.
are operated so that the winding is completed almost alternately. The five rows of transport magazines that make up the creel 2 of the spinning frame 1 are the roving frame RF1. It is constructed by connecting a large number of transport magazines 5 to suspend four times as many full rolls 7 as doffed at one time by RF2. A spinning machine 1 is located in a closed circuit consisting of a creel conveyance path 4, an empty winding magazine reserve section 10, a residual yarn bobbin processing device 11, an O-da 13, a full winding magazine reserve section 9, and a traveling rail 8a.
The number of transport magazines 5 required to form a creel 2 in groups
In addition to the rows, there are five rows of spare transport magazines.

Rover RF1. When the loader 13 completes the suspension of the full volume 7, the five rows of permuted transport magazines in which the bobbin hangers 6 for the number of spindles of the RF2 are suspended are automatically transferred to the full volume magazine reserve section by the action of the intermittent feed device 23. It is transported to the entrance of No. 9 and stopped at the same position. The worker is holding the Manshinomaki 7 suspended from the 5 rows of transport magazines transported by the intermittent feeder 23.
Check the product type, and press the corresponding product selection button on the control 119. As a result, if there are no 5 rows of transport magazines on any of the stock rails 9a to 9d of the Mitsshinomaki magazine reserve section 9,
The rail switching device @27 is switched to the stock rail 9a side on the side of one spinning machine.

After confirming that the rail switching device 27 has been completely switched and that the rail switching device 30 at the end of the connecting rail 17 has been switched to the magazine transport side, five rows of transport magazines are carried into the stock rail 9a. Then, by operating the type selection button and carrying in the 5 rows of transport magazines, the storage area corresponding to the stock rail 9a of the storage device 32 contains the information that the first row of transport magazines has been carried into the stock rail 9a and the transport magazine 5. The variety of Manshinomaki 7 hanging in the row is memorized.

In principle, the rail switching device 27 disposed at the entrance of the Mitsushi winding magazine reserve section 9 is switched by pressing the type selection button on the control panel 19, and the five rows of transport magazines are carried into the stock rails 9a to 9d. It returns to normal every time I go back. Further, the five rows of transport magazines are configured to be carried in preferentially from the stock rail 9a extending on the side closer to the spinning spinning 111 group (left side in FIG. 1). In other words, if you press the product selection button for the product type when there are no five rows of transport magazines on the four stock rails 9a to 9d,
As mentioned above, the rail switching device 27 is connected to the stock rail 9a.
When the product type selection button for the product type is pressed, the switching device 27 always switches to the stock rail 9a side until a total of 4 rows of 5 rows of transport magazines in the permuted sequence are carried into the stock rail 9a. Can be switched. In addition, if the 8 product selection button is pressed after 1 to 3 rows of the 5 product transport magazines have been carried into the stock rail 9a, the rail switching device/device 27 switches the stock rail 9a and the adjacent stock. It is switched to the rail 9b side, and the five rows of transport magazines of type B can be carried into the stock rail 9b. In other words, the type of Mitsshinomaki 7 suspended by the five rows of transport magazines carried into each stock rail 9a to 9d is suspended from the five rows of transport magazines carried first into each stock rail 9a to 9d. Determined by the variety of Manshinomaki 7,
Five rows of transport magazines hanging different types of Manshinomaki 7 are prevented from being carried into the same stock rail. Therefore, before carrying the five rows of permuted transport magazines to the stock rails 9a to 9d of the Mitsshinomaki magazine reserve section 9, the operator checks the type of Mitsshinomaki 7 suspended from the five rows of transport magazines. control! ! ! Just by pressing the 19 product selection buttons, 5 rows of transport magazines with 2 types of Shinomaki suspended can be transferred to spinning machine 1.
The creel 2 can be reliably connected to five rows of Nagatsuki conveyance magazines in which the same type of Manshinomaki is suspended.

Next, to explain the Shino change work, when the Shino rolls 7 suspended from the 5 rows of transport magazines that make up the creel 2 of the spinning machine 1 are used and become empty Shino rolls and need to be replaced, the operator replaces the Shino rolls. Turn on the changeover start switch located on the gear end side (right side in Figure 1) of the machine that requires this. Each machine in the first group of spinning machines has a selection switch (not shown) for selecting eight types of yarn, and which type of yarn is to be processed is set in advance by selecting the switch. When the Shino change start switch is turned on, the CPLJ 31 first confirms that the Shino change machine is stopped. Next, a detection device detects whether or not there is space in either of the stock rails 10a, 10b of the blank roll magazine reserve section 10 to accommodate the five rows of transport magazines in which empty rolls are suspended to be carried out from the blank change table. Based on the detection signal from 26, it is confirmed that there is space to accommodate the five rows of transport magazines. Further, the CPU 31 uses the data stored in the storage device 32 to determine the transport magazine row 5 waiting on each stock rail 9a to 9d of the Mitsushi-volume magazine reserve section 9.
It is sequentially determined from the stock rail 9a side closer to one spinning machine whether or not the leading transport magazine row is suspending the Manshinomaki 7 of the requested type (for example, the He type). and,
If the first 5 rows of transport magazines are those that suspend the requested type of Mitsshinomaki 7, it is determined whether it is a 4-car train or not, and if it is a 4-car train, a series of Shino change operations is started. A changeover start signal is outputted so that the changeover control circuit 33 that controls the changeover operation becomes operable. If none of the stock rails 9a to 9d has five rows of four-car transport magazines from which the requested type of Manshinomaki 7 is suspended, the Shino change signal is not output. If the above conditions are not satisfied and the changeover is not started within a certain period of time, the changeover start switch is turned on again later.

When the above-mentioned conditions are satisfied, the five rows of transport magazines in the creel transport path 4 of the Shino changing machine table are carried out from the creel transport path by the intermittent feeder 2°, and the transport magazines are transferred to the running rail 8a of the main transport path 8 and the empty Shino winding magazine reserve. The empty winding magazine reserve section 1o is
is carried into the specified location. On the other hand, the five rows of Nagatsuki's transportation magazines, which are waiting with the amount of Mitsshinomaki 7 of the same type suspended in the Mitsshinomaki magazine reserve section 9 for one Shino change, are backed up by the battery $15. It is carried through the running rail 8a into the creel conveyance path 4 of the shin changer stand, and the shin change work is completed. When five rows of transport magazines are taken out from inside the stock rail, the data of the corresponding stock rail stored in the storage device 32 is cleared by a signal from the reset input key 34.

The five rows of Nagatsuki transport magazines carried into the empty winding magazine reserve section 1o are transferred from the front side to the roving frame RF1. It is divided into permutations corresponding to the number of spindles of RF2, and is transported to a position where it can be engaged with the intermittent feed device 22a disposed downstream of the empty winding magazine reserve section 10. Then, the intermittent feed devices 22a to 22d are operated in sequence, and the five rows of conveyance magazines in the sequence are conveyed to the remaining yarn bobbin processing device 11. And the remaining thread bobbin processing device 1
After the remaining thread bobbin is removed in step 1, it is sequentially transferred to the loader 13, and in the loader 13, the Mitsushi windings 7 doffed by the roving frames RF1 and RF2 are sequentially suspended from the bobbin hanger 6 of the transport magazine 5. By the action of the intermittent feeder 23, the magazine is transported to the entrance of the fully wound magazine reserve section 9.

Note that the present invention is not limited to the above-described embodiment; for example, in the above-mentioned embodiment, the Manshin volume magazine reserve section 9
When transporting five rows of permuted transport magazines to the stock rails 9a to 9d, the operator visually confirms the type of Manshinomaki 7 suspended from the five rows of transport magazines and presses the type selection button on the control panel 19. The rail switching device 27 disposed at the entrance of the Mitsushi winding magazine reserve section 9 was configured to be switched by pressing . An identification device for identifying the type of Manshinomaki 6 may be provided, and the rail switching device 27 may be operated based on an identification signal from the identification device. It is also possible to adopt a configuration in which control is performed by a normal sequence circuit without using the CPU 31. Furthermore, the Rover RF1. In addition to RF2, a roving frame for spinning other types of products can be installed to change the configuration to spinning three or more types, or a row of transport magazines for long poems waiting in the Manshinomaki magazine reserve section can be replaced with a permuted transport magazine. The shape of each part may be modified without departing from the spirit of the invention, such as by constructing a long transport magazine row from the beginning instead of connecting rows.
It is also possible to change the configuration etc. arbitrarily.

Effects of the Invention As detailed above, according to the present invention, when spinning two or more types of yarn using a group of spinning machines arranged side by side, it is possible to change the threads of specific machines all at once without making a mistake in the type of yarn. This has an excellent effect in that it can be carried out reliably without any hindrance.
