Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a yarn processing device that performs yarn steaming treatment on a package between a winder and a double twister.

[Prior Art] Since spun yarn is in a false twisted state, it is necessary to fix the twist, and for this purpose, yarn steaming is performed using a steam device.

Conventionally, as shown in Japanese Patent Application Laid-open No. 61-215728, for example, thread steaming of cotsup was carried out in the conveyance path between a spinning machine and a winder that rewinds the spun spun by this spinning machine into a large package cage. There was a steam device installed.

[Problems to be solved by the invention] However, in the case of the above-mentioned conventional device, it is necessary to process a large amount of thread steaming at once due to the time required to feed the threads to the winder, so a large steam device is required. Not only that, but a large space was also required to install this steam equipment. Furthermore, since the processing speed of the winder was fast, it was not possible to take enough time for the thread steaming process.

Therefore, the purpose of the present invention is to solve the above-mentioned problems of the conventional technology, and to provide a yarn processing device that can reduce the size of the steam device, reduce the installation space, and allow sufficient time for the yarn steaming process. do.

[Means for Solving the Problems] In order to achieve the above object, the present invention uses a winder that rewinds the spun yarn into a large package cage, and a double twister that double-twists the threads of the two package cages together. A conveyance path is provided between the twister and the package cages carried out from the winder, which are stacked in two layers on a tray and conveyed to the double twister, and in the conveyance path is a casing that can be raised and lowered to airtightly cover the plurality of two-tiered packages on the conveyance path. and a steam supply/discharge part for supplying and discharging steam into the casing, and a steam device for thread steaming the package was provided.

[Operation] The packages carried out from the winder and stacked in two stages on the tray are covered by the descending casing while being conveyed to the double twister via the conveyance path, and are subjected to thread steaming treatment. In this way, instead of using the yarn in the kotsupu state, the yarn steaming process was carried out using packages equivalent to the amount of yarn for several tens of kotsupu, stacked in two tiers, and covered with a casing at the same time, so that the same amount of yarn could be processed. It takes only a few tenths of the space compared to doing thread steaming in a pot. Furthermore, since the winding speed of the double twister is slow, it is possible to take enough time for the yarn steaming process of the package.

[Example] Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a winder that rewinds the spun spun by a spinning machine (not shown) into a large package 2, and this winder 1 is equipped with a double-twisted yarn from the two package cages 2. A double twister 3 for further winding is connected via a conveyance path 4. A belt conveyor 5 is provided at the end of the winder 1 to transport the package cages 2, and a circulation path 6 is formed around the double twister 3 to circulate the package cages 2 and their empty bobbins on a tray 10. . This circulation path 6 includes the conveyance path 4, a return conveyor 7 that connects the empty bobbin discharge side of the double twister 3 and the carry-in side of the conveyance path 4, and the carry-in end of the return conveyor 7 and the discharge end of the conveyance path 4. It mainly consists of a first package circulation conveyor 8 that connects the packages 2 and a second package circulation conveyor 9 that returns only the packages 2 from the return conveyor 7 to the conveyance path 4.

The conveyance path 4 includes a pre-stage conveyor 4a located at the discharging end of the winder side conveyor 5 and connected to the discharging end of the return conveyor 7;
It is mainly composed of a second-stage conveyor 4b that connects the delivery end of the double twister 3a and the package delivery side of the double twister 3.

Further, a delivery device 11 is installed between the discharge end of the winder-side conveyor 5 and the front-stage conveyor 4a to remove empty bobbins from the tray 10 and to deliver the package 2 from the winder-side conveyor 5 onto the tray 10. ing. Incidentally, as shown in FIG. 3, the tray 10 is adapted to carry two package cages 2 in two stacks, one above the other.

A steam device 12 for thread steaming the package 2 is provided on the conveyance path 4. In the embodiment, this steam device 12 is used as shown in FIG.
is installed between a front stage conveyor 4a and a rear stage conveyor 4b which are perpendicular to each other, and has a package mounting table 13 which connects these conveyors 4a and 4b and forms the bottom surface of the steam chamber. This package mounting table 13 is formed to be large enough to line up three package 2s.
4 is supported so that it can be raised and lowered freely.

Further, a seal plate 15 on which the lower end of the casing 14 is seated is attached to the package mounting table 13, and a steam inlet 16 and a steam outlet 17, which are steam supply and discharge parts, are formed. is equipped with a valve 18,1 as shown in FIG.
A steam supply pipe 20 and a steam discharge pipe 21 each having a diameter of 9 are connected to each other.

A frame 2 stands up from one side of the package mounting table 13 in order to raise and lower the casing 14.
2 and the package mounting table 1, a ball screw screw rod 23 is mounted on bearings 24, 25.
A ball screw bearing 26 is attached to the casing 14 and is threaded onto the screw rod 23 of the casing 14.
A motor 27 is connected to the upper end of the motor 3 via pulleys 28, 29 and a belt 30.

In order to transfer the package 2 from the discharging end of the pre-stage conveyor 4a onto the package mounting table 13 disposed on one side of the discharging end of the pre-stage conveyor 4a, the package mounting table 1 at the discharging end of the pre-stage conveyor 4a is used.
A pusher 32 driven by a cylinder 31 is provided at a position facing 3. Note 33
is the guide rod attached to the pusher 32, 3
4 is a package stopper arranged at the discharge end of the front stage conveyor 4a.

In the above configuration, after the empty bobbin is removed by the package delivery device 11, the package delivery device 11 removes the empty bobbin from the tray 10 having the empty bobbin conveyed from the return conveyor 7 to the front conveyor 4a, and then the package conveyed from the winder side conveyor 5 is placed on the tray 10 having the empty bobbin conveyed from the return conveyor 7 to the front conveyor 4a. 2 is delivered. When the packages 2 are conveyed to the unloading section by the pre-stage conveyor 4a, they are transferred one by one onto the package mounting table 13 by the pusher 32. When a predetermined number of package cages 2 are lined up on the package mounting table 13, the casing 14 is lowered by rotating the screw rod 23 to cover the package 2, and steam is placed in the steam chamber partitioned by the casing 14 and the package mounting table 13. The package 2 is steamed by filling it with steam through the supply and exhaust pipes 20 and 21. When the thread steaming is completed, the steam in the steam chamber is suctioned and discharged through the steam exhaust pipe 21, and then the casing 14 is raised. The package 2 that has been subjected to thread steaming in this way is pushed out from above the package mounting table 13 to the carry-in end of the rear conveyor 4b via the package 2 carried onto the package loading table 13 by the pusher 32, and then transferred to the rear conveyor 4a. Therefore, it is conveyed to the double twister 3.

In this way, thread steaming is performed in the package 2 state, so unlike conventional equipment that performs thread steaming in the packaged state, the same amount of thread can be processed in a few tenths of the space. This makes it possible to downsize the steam device and reduce its installation space. Further, since the winding speed of the double twister 3 is generally slow, a sufficient amount of time can be taken for the yarn steaming process of the package 2.

The steam device may have a structure in which a steam chamber is formed below the package mounting table 13 in which the package 2 is lowered and accommodated, and the upper part of the steam chamber is sealed with a lid during thread steaming. Further, a wax injection section may be provided in the steam chamber so that waxing can be performed in addition to thread steaming. Furthermore, the size of the package mounting table 13 is not limited to the embodiment.

[Effects of the invention] According to the invention, the following excellent effects are achieved.

The yarn steaming process is performed by stacking the yarn equivalent to several tens of threads in two tiers and covering them with casings at the same time. Unlike the above device, only a few tenths of the space is required to process the same amount of yarn, making it possible to downsize the steam device and reduce its installation space.

Since the yarn steaming is performed before the double twister, the winding speed of the double twister is slow, so it is possible to take enough time for the yarn steaming process of the package.

If yarn evaporation is performed before the yarn is evaporated and then immediately fed to the winder, the moisture in the yarn will cause the slab catcher (especially the capacitive type) to malfunction, so it is necessary to take time to dry the yarn after evaporation. Since the double twister does not have a slab catcher in the first place, it can be supplied to the double twister immediately after the thread steaming process. Moreover, since the yarn is supplied to the double twister in a moist state, it is possible to prevent the occurrence of fluff due to ballooning of the unwound yarn.
