Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to the following: Every time a pre-processing machine, such as a first liner, is full,
The delivery can is automatically exchanged with an empty can, and the previously exchanged full can is sent out to the rear side of the back-end machine, such as a second line forming machine, etc., and in connection with sending out the full can. Nα3 of post-processing machine A predetermined number of feed cans and empty cans are intermittently moved to a predetermined amount, and then the empty cans that have been used up in the processing machine are sent one by one to the pre-processing machine, and the pre-processing machine and the post-processing machine This device relates to a can circulation movement device between spinning machines that circulates a predetermined number of cans arranged in a spinning machine, and can be applied to spinning machines such as those used in the filament process where a front-process machine and a post-process machine correspond one-to-one. This device is mainly suitable for continuous spinning machines with two or more steps.

BACKGROUND OF THE INVENTION Conventionally, many devices have been proposed for circulating and moving the delivery cans and empty cans of a front-end machine, as well as the feed cans of a back-end machine, as described above. Among them, in the conventional device disclosed in Japanese Patent Publication No. 36-18372, a predetermined number of cans are fixed on a large turntable, and the fixed number of cans are moved all at once by intermittent rotation of the turntable. It looks like this. In addition, Japanese Utility Model Publication No. 41-13545 discloses that there is a linear can passage in front of the front process machine for changing cans in the left and right direction of the machine base, which communicates with the can passage of the front process machine, and a can passage for the rear process machine. A can circulation moving device is disclosed which includes a can circulation passage consisting of a T1-shaped can passage in which feed cans and empty cans are disposed. Furthermore, in Japanese Patent Publication No. 41-9816, a can exchange arm having four arms and a semicircular can passage are provided in front of the preprocessing machine, and the preprocessing machine is provided with a can exchange arm having four arms and a semicircular can passage. A straight can passageway in which full cans sent out from the side are arranged;
A polygonal can circulation moving device is disclosed, which is formed by an inclined can passage for arranging the feed cans of a post-processing machine, and a can passage for sending empty cans exhausted in the post-processing machine to the front-processing machine. . This special public service 1977-
Publication No. 9816 and the above-mentioned Utility Model Publication No. 41. - The can circulation moving device disclosed in Publication No. 1.3545 creates a space for one or more cans or two cans in a passageway such as the delivery side of full cans exchanged on the front-process machine side. Two locations are provided for replacing cans in the front-end machine and for moving full cans after replacement.
The feed cans n 5 or empty cans of the post-processing machine are moved separately according to a predetermined order.

Problems to be Solved by the Invention In recent years, the speed of various spinning machines has been increased, and in particular, the speed of various spinning machines has been increased.
The spinning speed reaches 800 meters per minute, compared to the previous 15 meters per minute.
This is more than 5 times as much as the linear machine, which costs around 0 US. In addition, in recent years, in order to reduce the number of can exchanges which increases with the increase in speed of wire forming machines, the cans have been made larger and the can exchange has been automated. However, there is a limit to the rationalization of such a single spinning machine, and in recent years, the filament process consisting of a first filament machine and a second filament machine, or this filament process and carding, has been developed. Continuous spinning, which is a process that connects processes, is now being recognized again.

In addition, in such continuous spinning, a predetermined number of slivers spun from multiple carding machines are directly supplied to the first filament machine, whereas in the filament process, the first filament machine The spun sliver is temporarily stored in a deliverance, and the Nα6 deliverence, which was automatically exchanged in the first drawing machine, is used as the feed sliver of the second drawing machine.
The sliver is fed to the rear side of the wire drawing machine, and a predetermined number of slivers pulled out from the feed can are superimposed in parallel and fed to the drafting section of the second wire drawing machine, and the wire drawing machine The machine is stopped and the cans are automatically replaced every time the cans are full. However, as with recent filament machines, when the spinning speed reaches 800 meters per minute, the feeding speed of the sliver on the supply side also increases to more than 100 meters per minute. In a single-filament machine, if the automatic can exchange is not completed in a short time, a large amount of sliver will remain on the supply side, making subsequent spinning difficult.

In addition, a predetermined number of feed cans placed on the rear side of the second wire drawing machine are set up to taper by gradually reducing the sliver storage capacity of each can to a predetermined amount during production, and the sliver is sequentially exhausted starting from the cans on the negative side. When one of the feed cans becomes empty or most of the sliver is used up, the feed can is intermittently moved one by one during operation of the machine. However, as mentioned above, the sliver on the supply side of this second sliver is also
Because it is being pulled out from the can at a higher speed than 00Na 7 US,
If this intermittent movement of the feed can is carried out rapidly during operation, cuts or uneven thickness may occur in the sliver being fed. In recent years, high-speed wire forming machines have adopted cans equipped with spring-loaded catch plates to prevent the spun sliver from flying out of the cans at the beginning of operation.

For this reason, when a full can leaves the coiler table after replacing the can, a portion of the stored sliver protrudes greatly from the two sides of the can due to the spring force and restoring force of the fibers, and the amount of protrusion increases to 400 to 500 millimeters. Then, the full can is sent to the post-processing machine with the sliver protruding. In this case, the aforementioned Jikosho 41. -1.354
When the conventional can circulation moving device disclosed in No. 5 and Japanese Patent Publication No. 41/9816 is adopted, a full can with a protruding sliver collides with a stationary can in front, causing the sliver to collapse. It may cause trouble. Furthermore, the conventional device disclosed in Japanese Patent Publication No. 36-18372 requires a revolution-revolution coiler in order to accommodate the spun sliver of the first filament machine in a coiled manner in a stationary can. Due to its structure, this revolving coiler has a
The limit is about 50 m/min, which is extremely difficult to achieve with the recent spinning machines, where the spinning speed has reached 800 m/min. It had drawbacks such as being large.

Furthermore, in a can circulation moving device based on continuous spinning, if the cans with different total weights, from full cans to empty cans, placed on the circulation path, are not reliably moved to a predetermined amount, the subsequent This will interfere with the automatic exchange of cans and the automatic supply of sliver to post-processing machines, causing trouble.

Means for Solving the Problems As mentioned above, the present invention was developed as a result of various studies on the current state of spinning machines such as wire spinning machines in recent years, where speeding up and large packaging have been promoted, and conventional can circulation moving devices. The gist of this is that the front process machine and the Na 9 back process engine are placed at an appropriate distance in the front and back direction of the machine, and the delivery of the front process machine, empty cans, and after the cans are replaced. A semicircular can passage in which full cans are arranged communicates with a semicircular can passage on the front-processing machine side, and a U-shaped can in which the feed cans and empty cans of the post-processing machine are continuously arranged. A can circulation path is provided from the passageway, and the U-shaped can passageway on the back-end machine side is equipped with an actively driven roller conveyor that rotates intermittently every time the front-end machine is full. In front of the machine, there is an intermittent rotating can exchange arm with at least three arms, and this can exchange arm automatically exchanges the delivery can and empty can every time the previous process machine is full, and the previous process. The full can is fed from the standby position to the sliver supply position on the back-processing machine side, and the next empty can is fed into the front-processing machine. The roller conveyor is set at a speed higher than the speed of the cans on the roller conveyor, and the previous full can sent out from the standby position by the rotation of the can exchange arm is moved to the mouth Nu1. 0 As the conveyor rotates, it catches up with the moving feed can and moves to a predetermined sliver supply position while pushing the feed can in front, thereby moving each feed can on the roller conveyor to the next predetermined position. An object of the present invention is to provide a can circulating and moving device which eliminates the drawbacks of the prior art and enables continuous spinning in a spinning machine such as a filament machine, which promotes high speed and large packaging. It is.

Operation The can circulating device of the present invention as described above has a tapered setup in advance by gradually reducing the sliver storage capacity to a predetermined amount on the U-shaped can passage on the back-processing machine side equipped with an actively driven roller conveyor. A predetermined number of slivers (same number as the number of doublings) and at least one empty sliver are consecutively arranged, and a predetermined number of slivers drawn automatically or manually from each feed can are polymerized in parallel to perform post-processing. It is supplied to the drafting section of the machine. In addition, on the semicircular can passage provided on the front side of the front-processing machine, a delivery can for the Nn1l front-processing machine, an empty can for can replacement, and a full can for which the can has been replaced are placed, one each. The sliver spun by the front-end machine is then stored in the delivery case. After that, each time the delivery can of the front-end machine becomes full and the front-end machine stops, the can exchange arm and roller conveyor rotate according to the full can command.
Can exchange on the front-processing machine side and movement of the feed can and empty can on the rear-processing machine side start almost simultaneously, and when the can exchange arm on the front-processing machine side rotates by a predetermined angle, the can exchange and the empty cans on the front-processing machine side are replaced. At the same time, the full delivery cans are moved to the next position and the cans are automatically exchanged, and at the same time, the previously full cans that were in the standby position are also sent to the sliver supply position on the back-processing machine side.

However, the can exchange speed using this can exchange arm is limited to the roller conveyor on the back-processing machine side or the roller conveyor.
Because the speed is set to be faster than the speed of the second can, the previous full can that was sent out from the standby position by the rotation of this can exchange arm is being moved by the rotation of the roller conveyor in the middle of being sent out. When it catches up with the feed can and moves to the predetermined sliver supply position while pushing the feed can in front, each feed can on the roller conveyor moves one can reliably and reaches the predetermined next position. , the can exchange arm and the roller conveyor are simultaneously stopped by an appropriate detection command. Also,
Along with the movement of the feed cans mentioned above, the empty cans placed on the roller conveyor also move to the front-process machine side, and during this movement, the can exchange arm sends them to the standby position on the can passage of the front-process machine side and waits. do. In this way, the replacement of the cans on the front-process machine side, the sending out of the previous full cans, the movement of the feed cans on the rear-process machine, and the feeding of empty cans to the front-process machine side are completed, and the front-process machine is started. On the other hand, when the can is replaced, the sliver connected between the full can and the coiler is cut by the movement of the full can. In addition, the last full can that was moved from the standby position to the sliver supply position is automatically or N
α13 is manually spliced onto the end of the sliver being fed and is continuously fed to the drafting section of the post-processing machine.

EXAMPLE Hereinafter, the present invention will be explained in detail with reference to an example shown in the drawings. In FIGS. 1 and 2, numeral 1 indicates a 1-head, 1-delivery first filament machine which is a pre-process machine for the filament process. A second wire-stretching machine 2 with one head and one delivery, which is a post-processing machine, is arranged at an appropriate interval, and between the first wire-stretcher 1 and the second wire-stretcher,
The can circulation moving device 3 of this embodiment is provided. This can circulation moving device 3 has a semicircular can passage 7 in which a delivery can 4 of the first filament machine 1, an empty can 5 for replacing cans, and a previous full can 6 are disposed in the first filament machine 1. A candish wheel 8 for the can dish 4 is arranged in the center of the can passage 7, and the can dish wheel 8 arranged on the can dish wheel 8 rotates in a predetermined direction to move the machine. The spun sliver sent out through the coiler of the stand is formed into a coil shape and Nα
14 to be stored in the delivery case 4, and a predetermined number of cans (same number as the number of doublings) of the second wire wire machine 2 are placed at the front end of the semicircular can passage 7 on the first wire wire machine side. In this embodiment, a case of five is shown), and the feed sequence 9 is
A U-shaped can passage 11 in which at least one empty can 10 is disposed is connected, and the U-shaped can passage 11 on the second filament machine side and the semicircular can passage 11 on the first filament machine side are connected. A can circulation passage 12 is formed by the passage 7, and the U-shaped can passage 11 on the side of the second filament machine includes:
The first wire-stretching machine 1
is equipped with an actively driven roller conveyor 13 that rotates intermittently in a predetermined direction every time the cans are full;
A can exchange arm 16 having more than one arm 15 (four arms is shown in the illustrated example) is fixed to the can exchange arm 16.
The vertical shaft 14 is rotated intermittently in the direction shown in the figure at a predetermined angle every time the first wire stripping machine is full, through an appropriate drive source such as a motor M3, a Cheno wheel, and an appropriate transmission mechanism such as a Cheno wheel. Further, the can exchange speed by the can exchange arm 16 is configured to move faster than the roller conveyor 13.
Alternatively, the can circulation moving device 3 is configured such that the speed is set higher than the speed of the cans 9 and 10 on the roller conveyor. The roller conveyor [3] and the can exchange arm 16 are driven by motors M1, M2, and M2, which are the respective driving sources.
3 is electrically connected to an auto counter (not shown) equipped on the first wire stripping machine 1, and starts almost simultaneously every time the first wire stripping machine 1 in operation is stopped according to a command from the auto counter, When the can exchange arm 16 rotates by a predetermined angle, it is stopped almost at the same time in response to the detection command, and the operation of the first wire drawing machine 1 can be resumed in response to the detection command.

In this embodiment, in which the can circulation moving device 3 as described above is arranged between the first wire drawing machine 1 and the second wire drawing machine 2, the U-shaped can circulating device 3 on the second wire drawing machine 2 side equipped with the roller conveyor 13 is used. A predetermined number of feed cans 9 (same number as the number of doublings, the illustrated example shows a case of five) of which the sliver storage capacity is gradually reduced to a predetermined amount and are stacked in advance on the can passage 11 are placed on the can passage 11, and at least one Empty book cans 10 (the illustrated example shows the case of one book) are arranged consecutively as shown in the figure, and a predetermined number of slivers 17 pulled out automatically or manually from each feed can 9 are guided as shown in the figure. They are polymerized in parallel via rollers 18 and the like, and then supplied to the drafting section 19 of the second filament machine 2. In addition, on the semicircular can passage 7 provided on the front side of the first wire stripping machine 1, there are a delivery can 4 for the first wire stripping machine, an empty can 5 for replacing cans, and a full can for which the can has been replaced. One can 6 is arranged for each delivery can 4, and the spun sliver of the first filament machine 1 is accommodated in the delivery can 4. Thereafter, when the delivery sensor 4 of the first striping machine 1 becomes full and an auto counter (not shown) is activated, and the first striping machine 1 is stopped by the full can command, the auto counter etc. Based on the full can command, the can exchange arm 16 and the roller conveyor 13 exchange the empty can 5 at Nα171 and the full can delivery can 4 via the respective motors M1, M2, M3, etc.
This automatic exchange and the movement of the feed can 9 and the empty can 10 on the second wire drawing machine 2 side are started almost simultaneously, and when the can exchange arm 16 on the first wire drawing machine side rotates by a predetermined angle in the direction shown in the figure, the The empty can 5 and the full delivery can 4 that were in the standby position on the 1-line machine side are moved to the next position and automatic can exchange is performed, and at the same time, the previous full can that was in the standby position is moved to the next position. 6 is also delivered to the sliver supply position on the second filament machine side. However, this can exchange arm 16 has a can exchange speed that is higher than that of the roller conveyor 13 on the second wire forming machine side.
Or, because the speed is set higher than that of the cans 9 and 10 on the roller conveyor, the rotation of the can exchange arm 16 causes the previous full can 6 sent out from the standby position shown in FIG. The feed can 9 is being moved by the rotation of the roller conveyor 13 during feeding.
Ha 18 catches up with the feed can 9 and moves to the predetermined sliver supply position while pushing the feed can 9 in front, and when the Ha 18 sliver 9 reliably moves for one can and reaches the predetermined next position, the can exchange arm 16 The roller conveyor 13 is simultaneously stopped by a command from a detection means such as a limit switch (not shown). In addition, as the feed cans 9 move, the empty cans 10 placed on the roller conveyor 13 also move toward the first stripping machine, and during this movement, the can exchange arm 16 moves the can passage 7 on the first stripping machine side. It is sent to the standby position above and waits until the next can exchange. In this way, the cans can be automatically exchanged on the first stripping machine side, the previous full can 6 is fed out, the feed can 9 is moved on the second striping machine side, and the empty can 10 is moved on the first striping machine side. When the feeding is completed, the operation of the first wire forming machine 1 is restarted. On the other hand, the sliver connected between the replaced full can and the coiler is cut by the movement of the full can. In addition, each time one of the feed cans 9 becomes empty, the sliver end of the previous full can 6 that was moved to the sliver supply position is automatically or manually transferred to the end of the sliver that is currently being supplied. It is continuously supplied to the tensioner Nα 19 of the second wire drawing machine 2.

In the embodiment described in -, the motor M4 is installed at the standby position of the previous full can 6 placed in the can passage 7-hi provided on the side of the first stripping machine 1, as shown in FIG. A turntable 20 is provided which moves intermittently together via a cheno wheel and a chenno, etc., and the full can 6 placed on the turntable 20' is slowly rotated in response to a can exchange completion command, etc., and the sliver end is is detected by a phototube (not shown), etc., and positioned at a predetermined position.Furthermore, the positioned sliver end is pulled upward by a gripping means such as a suction arm that can be raised and lowered and rotated, and the sliver end is automatically extracted. Thereafter, after the full can 6 is moved to a predetermined supply position, the automatically fed sliver end may be automatically supplied to the second filament machine 2 via a suitable sliver supply device. However, since these sliver end gripping means and sliver supply device are not the gist of the present invention, detailed explanation thereof will be omitted.

The present invention has a can circulating passage of a can circulation moving device installed in front and rear process equipment as shown in L below. The U-shaped can passageway on the side of the subsequent processing machine is equipped with an actively driven roller conveyor that rotates intermittently every time the preprocessing machine is full.
A can exchange arm that rotates intermittently and has at least three or more arms is installed, and this can exchange arm automatically exchanges the delivery can and empty can every time the previous process machine is full, and exchanges the previous full can. and feeding the next empty can to the front-processing machine side, furthermore, setting the can exchange speed for this can exchange to a speed faster than the speed of the can on the roller conveyor or the roller conveyor, As the can exchange arm rotates, it moves from the standby position to the previous full can keraiba feeding position, which moves each feed can on the roller a21 conveyor to the next predetermined position. This reduces the machine stoppage time when replacing the carding can, reduces the amount of sliver stagnation fed from the connected carding machine, and also reduces most of the movement of the feed can on the downstream machine side. Since the feeding can can be carried out at high speed, the sliver in progress will not be cut or unevenness will occur when the can is moved, and the feed cans, which have different total weights due to the taper setup, can be moved near the end of their movement. Since the cans are pushed by the previous full cans sent out by the can exchange arm and reliably move to their respective predetermined next positions, there is no problem with the automatic supply of sliver or the automatic exchange of cans that will be carried out thereafter. In addition, when the previous full can is sent out from the front process machine side by the can changing arm, the sliver that protrudes from the top of the can will not collapse due to the impact when the can is caught up, and the sliver that protrudes from the top of the can will not collapse. It has the feature that it does not interfere with the automatic feeding of sliver to be carried out, and as a result, continuous spinning can be carried out using spinning machines such as filament machines, which have recently become popular for speeding up and large packaging.
