Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to doffing of a full package from a textile machine, and more particularly to a doffing device for a yarn processing machine.

[0002]

Until relatively recently, yarn packages have been manually picked up from the package winding mechanism of textile machines,
It is then picked up by a truck or moved to a storage area. Due to the increasing size of packages to reduce doffing cycles from textile machines, and the heavy weight of the packages, manually doffing such packages is a daunting task. And, package damage is more likely to occur. Therefore, proposals have been made to automate the package doffing work.
One such proposal is British Patent Publication No. 2248245.
No. specification.

The device described therein has a track extending around the building in which the textile machine is located, between the machine, the empty tube supply station and the full package receiving station, A carrier travels along this track to transport the empty tubes to the machine and to transport the full package from the machine. Transfer devices located at the supply station, the machine and the receiving station transport the empty tubes or packages between the station and the carrier or between the carrier and the machine as appropriate. All operations are controlled by a computer, which can also control many similar machines in the same factory.

[0004]

Although the above-described arrangement is very ideal from the viewpoint of reducing the amount of manual handling of heavy packages, it is very economically expensive.

A much less expensive proposal is to transfer the full package from the processing machine to a trolley or to a wheeled cassette, where the cassette is lined with pegs or other package receiving means. The pegs have a one-to-one correspondence with the package winding mechanism of the textile machine. In a typical yarn processing machine, 108 package winding mechanisms are arranged in three rows (row) on one side of the processing machine, and four winding mechanisms are provided for each partition (bay) of each row. Done 9
There are two partitions. Thus, preferably, the cassette is provided with pegs or other package receiving devices in three stages and the number of columns (so-called weights) is selected to suit a particular machine user. If there is only one frame (weight) per cassette, then 36 cassettes will be doffed from each side of the machine, which may not be automated as in the expensive arrangement described above. , Very time consuming.

A more preferred arrangement is to use a cassette with four frame (weight) pegs and a length equal to the partition length. This requires nine cassettes on each side of the machine and their removal is much less time consuming than the one frame (weight) arrangement.

In all cases, all cassettes are simultaneously ejected by the towing device into the "train" state, however, the trains are so long that each maneuver has to be carried around the factory. It will be very difficult to maneuver unless it is divided into several packages with 108 packages or less.

In order not to make a place (weight) in any part of the machine that does not produce a finished yarn of satisfactory quality, it is necessary to identify where each package was produced after being fried from the machine. What you can do is important. Therefore, it is desirable that the packages be fried in order from the machine, and that the order of the packages be maintained during the transfer operation to the package storage station. In the first device described above, maintaining such a package order can be easily achieved,
By manually removing a large number of cassettes, maintaining this order is not guaranteed.

[0009]

OBJECTS OF THE INVENTION It is an object of the present invention to provide an apparatus for doffing packages from a textile machine that is less expensive than the first apparatus described above and is also more convenient than the second apparatus described above. Moreover, it is to provide a device that does not take much time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. 1, one side of a double-sided yarn processing machine 10 is shown, and this processing machine 10 includes a creel 11 of a package 12 for supplying a raw yarn,
For each yarn, the first supply device 13, the heater 14, the cooling plate 15, the false twist unit 16, itself and the first supply device 1
It comprises a second supply device 17, a second heater 18, a third supply device 19 and a winding mechanism 20 which act so as to draw the yarn between them. The second heater 18 and the third supply device 19 may be appropriately omitted depending on the desired textured yarn characteristics. The package winding mechanism 20 is arranged in three rows (row) extending in the longitudinal direction of the processing machine, and each stage has 36 frames (so-called weight) of package winding in each step of the processing machine 10. Nine partitioning bays
There are four frames (weights) in each partition.

A worker passage 21 is provided between the creel 11 and the main frame 22 of the processing machine, and the worker passage 21 is provided with a transfer device 23 and a cassette 24. If the cassettes 24 are of the type shown in FIG. 2, there may be 18 such cassettes arranged in the longitudinal direction of the processing machine 10 and only one such cassette 24 is provided. It is visible in Figure 1. The cassette 24 comprises, as shown in FIG. 2, each a frame 25 on which twelve package receiving devices are provided as pegs 26 arranged in six stages and four frames in the figure. Has been. Cassette 2
The vertical spacing of the steps of the pegs 26 on the 4 is substantially 60 the vertical spacing of the steps of the package winding mechanism 20 of the processing machine 10.
%, While the lateral frame (weight) interval of the pegs 26 on the cassette 24 is the package winding mechanism 2 along the machine 10.
It is substantially half of the frame (weight) interval of 0.

Each cassette 24 is provided with wheels 27 so that the cassette 24 can run on a machine track arrangement 28 which is parallel to the processing machine 10 and slightly above the floor 29. Is provided. Attached to the cassette 24 is a connector 30 (FIGS. 2-5) that allows two or more such cassettes 24 to be connected in a "train" condition.

The trolley 31 (FIG. 6) is provided with an auxiliary trolley track arrangement 32 above the floor surface 29 at the same height, so that the cassette 24 extends from the machine track arrangement 28 to the trolley 3.
It is possible to drive to 1. As can be seen from FIG. 6, the track arrangement 32 of the trolley is formed in a U shape.
One cassette 24 can be housed in the trolley 31, four cassettes 24 being located next to each other along the longitudinal side of the trolley and one cassette 24 being located on the front side of the trolley 31. In this way, the nine sets 24 of cassettes 24 are stored in one relatively short trolley 31 which makes it possible to move more easily in the factory where the textile machine 10 is mounted.

As can be seen from FIG. 7, the factory layout may include a supply station 33 of empty tubes 34,
In the first possible operating mode two trolleys 31
Are moved to this supply station 33 manually or, in particular if connected, by a towing vehicle (not shown). Each trolley 31 is loaded with nine cassettes 24, and 216 empty tubes 34 can be attached to the pegs 26 of these cassettes 24 by a manual or mechanized transfer device (not shown). When the package being wound on at least one side of the textile machine 10 is substantially full, the trolley 31 is moved to that side of the machine 10 and the cassette 24 is transferred to the machine track arrangement 28. The eighteen cassettes 24 extend along the entire length of the machine 10, and the pegs 26 located on the alternate frames (weights) have a predetermined positional relationship with the package winding mechanism 20 of the machine 10.

The transfer device 23 then replaces the full package from the processing machine 10 with the empty tube 34 from the cassette 24. This replacement first involves the first frame (weight) on that side of the processing machine 10. The package 35 of the three winding machines of FIG.
As shown in FIG. 3, the empty tubes are replaced with the empty tubes 34 in the upper row and the alternating rows of the same frame. In order to operate in this way, the transfer device 23 moves from one end of the machine 10 toward the other end on the rail 36 provided along the machine 10 and near the first frame of the winding package 35. , For example machine 10
The magnetic marker provided at the position is detected and the operation is stopped.

The transfer device 23 is provided with an arm (not shown), and this arm projects outside the transfer device 23 and engages with three yarns as the yarns move upward toward the package 35. Then, these yarns are retracted so as to be drawn into the yarn passage of a cutter (not shown) provided in the transfer device 23. The cutter is then activated to cut the yarn,
Suction device (not shown) in which the yarn end is provided close to the cutter
To suck. Three transfer cradle 37 extend to remove the package 35 from the winding mechanism 20 and bring them to the transfer device 23. At the same time, three transfer pegs of the transfer mechanism (not shown) of the transfer device 23 extend from the transfer device 23 to grip the empty pipe 34, and the empty pipe 34 is taken out from the peg 26 of the frame of the cassette 24. Held on a transfer peg.

The transfer mechanism is then rotated 90 ° and the empty tube 34
The transfer peg provided with is aligned with the winding package 33, and has a height different from that of the package 35 in the vertical direction. The package 35 is then transferred to the sets of transfer pegs of the transfer device and moved vertically to position the empty tube 34 in the transfer cradle 37, which is now an empty take-up mechanism. The empty tube 34 is extended to 20 and positioned. The transfer mechanism again moves vertically and pivots 90 °, and the package 35 is transferred to the empty peg 26. The transfer device 23 then moves along the machine 10 and is positioned in the frame next to the full package 35 of the machine 10. The above-described exchange operation by the transfer device 23 between the full-roll packages 35 and the empty tubes 34 is repeated, and this exchange operation causes all the full-package 35 to be doffed from that side of the machine 10 and the empty tubes It continues until 34 is fed to the winding mechanism 20 on this side which is empty. In the winding mechanism 20, each frame of the full-winding package 35 has an empty tube 34.
As it is replaced by the yarn end, the yarn end is gripped by a yarn hooking device (not shown) of the transfer device 23 and picked up from the suction device described above, and the yarn hooking device extends toward the machine 10, whereby the yarn Is hooked on the empty tube 34. The processing of the yarn including the winding of the new package 35 is started.

The cassette 24 then becomes as shown in FIGS. The cassette 24 may be ejected here if desired, but in operation in this mode the cassette 2 is dispensed until the winding of the package 35 is completed.
4 may rest on the side of the machine 10. Transfer device 2
The doffing of the full-wrapped package 35 from the machine 10 and the removal of the empty tube 34 from the cassette by means of 3 are repeated as described above, the transfer mechanism from the initial position to the cassette 24 and the internal stage of the cassette. It is moved by the distance between the direction and the frame direction. When this second package doffing operation is completed, the cassette 24 becomes as shown in FIGS. 4 and 5. At this time, the cassette 24 needs to be ejected,
The two trolleys 31 are transferred to the trolley track arrangement 32, and the cassettes 24 mounted on the trolleys 31 are transferred to the packaging station 38. Package 35 is cassette 24
May be removed manually or by another mechanized transfer device (not shown). This mode of operation allows the doffing of the package 35 twice from the machine 10 without manual intervention, which allows the machine 10 to operate overnight without a night shift. This significantly reduces the operating costs of the machine 10.

In another operating state, one trolley 31 with nine cassettes 24 mounted as in FIG.
Are brought to the machine 10 either manually or by a towing vehicle. The nine cassettes 24 are then transferred to the track arrangement 28 of the machine and extend along substantially half the length of the machine 10. The removal of the empty tubes 34 from the first frame of the pegs 26 of the first cassette 24 and their replacement with the full-roll package 35 from the first frame of the winding mechanism 20 are performed as described above. When this is complete, the cassette 24 is moved along the machine 10 approximately the inner frame spacing of the cassette, and the empty tube 34 from the second frame of the peg 26 is removed and the second of the winding mechanism 20 is removed. It is replaced with the package 35 from the frame. This operation is for cassette 2
4 is repeated as the transfer device 23 is moved along the machine 10 at about half the speed at which it is moved.
This operating condition causes all packages 35 from one side of the machine 10 to be stored in nine cassettes 24 and placed on one trolley 31. As a result, the machine 10
With all 108 packages 35 installed from one side of the trolley 31, maneuvering the trolley 31 along the factory is much easier than previously described, especially when space is limited. Become.

Optionally, two yarns being treated at adjacent locations on the machine 10 may be combined to form a single yarn. In this case, the first mode of operation described above allows doffing four full roll packages 35 from the machine 10 before the cassette 24 is transferred to the trolley 31 and goes to the packaging station 38. . In the operation of the second mode described above, when a yarn in which two yarns are combined is manufactured, the two-dough package 35 can be stored in the trolley 31 before the trolley 31 is moved to the station 38. is there.

The present invention requires much less human intervention than previous methods, thereby reducing the operating costs of the machine 10. Moreover, it offers greater flexibility of operation than is possible with known devices. In addition, any of the modes of operation described above maintains the doffing sequence of full-wound packages from the winding machine on the cassette and trolley, thereby maintaining such sequence to the storage station. This allows the machine location that manufactured the quasi-standard package to be easily identified.
