Abstract

PURPOSE:To enable the supplying a sufficient packed volume of sliver to all spindles without causing any trouble by using a space required for the arrangement of only four rows of cylindrical cans, even in a spinning machine which has such a spindle pitch as to require five-rows arrangement of can in its back side when the cylindrical cans are used. CONSTITUTION:Can-transferring apparatuses 2a and 2b are placed in two rows parallel with the longitudinal direction of a flyer frame 1 in its back side. The flyer frame 1 has such values of pitch and number of the spindles la as to require five rows if the cylindrical cans would be used for supplying sliver to all spindles. On each of the can-transferring apparatuses 2a and 2b, cans 3 of a half number of the total spindles are placed in a raw in such a manner that the longitudinal direction of the cans coincides with the sending-out direction of the sliver S. The can 3 is a case with a bottom, which has a rectangular cross section having the ratio of width vs. length of about 1:4-5 and is designed to have almost the same amount of volume as that of the cylindrical can. Sliver S in each can 3 is supplied to each corresponding spindle 1a via a corresponding feed roller 14 placed above the can 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliver feeding method for a spinning machine, and more particularly to a sliver feeding method suitable when the cans arranged in a plurality of rows behind the spinning machine stand are large.

[0002]

2. Description of the Related Art In a roving machine, it is essential to perform a sliver splicing work for joining a sliver in progress and a sliver in a full sliver can for supplying new sliver before the sliver is completely exhausted. Generally, in the roving machine, the operation of the machine stand is stopped during the sliver splicing work in order to avoid an illegal draft of the sliver. Also, the can is generally formed in a cylindrical shape,
In order to reduce the number of times the machine stand is stopped due to the sliver splicing work, a large diameter machine with an inner diameter of about 20 inches (508 mm) and a height of about 42 inches (1067 mm) is usually used. On the other hand, the spindle pitch of the roving frame depends on the spinning number,
It is about 110 to 130 mm, which is smaller than the can diameter.

Therefore, as shown in FIG. 10, the cans 52 are arranged in a plurality of rows behind the roving machine stand 51, and the feed rollers 53 are arranged at the upper positions corresponding to the rows of the cans 52, respectively. . Then, each feed roller 53
A guide (not shown) is provided at a position corresponding to each can, and the sliver S is guided to the weight 54 of the roving machine stand 51 via the guide.

Further, in recent years, various automations have been carried out in spinning factories for labor saving and productivity improvement, and an automatic sliver splicing machine for a roving machine is also disclosed (for example,
JP-A-2-91233, etc.). Further, a method has also been proposed in which a roving machine and a kneading machine are connected by a can conveying device to automatically convey a can.

[0005]

When a large diameter cylindrical can is used, the number of rows of the cans 52 being spun arranged behind the roving machine stand 51 is 4 due to the relationship between the weight pitch and the can diameter. There are cases where the number of rows is good and cases where five rows are required.

For example, in a roving machine with a weight pitch of 130 mm and 120 weights, the can 52 has an inner diameter of 508 mm,
If the outer diameter of 520 mm is used, the length of the winding portion of the roving machine is 130 mm × 120 = 15600 mm,
A length of 520 mm x 3 with 30 cans 52 arranged in a line
It becomes equal to 0 = 15600 mm. Therefore, Kens 52
The sliver S can be supplied to all the weights 54 by arranging in four rows.

However, in a roving machine with a weight pitch of 110 mm and 120 weights, the length of the winding section of the roving machine is 110
mm × 120 = 13200 mm, which is approximately equal to the length 13000 mm in which 25 cans 52 having the same diameter are arranged in one row. Therefore, the can 52 is placed behind the roving machine base 51.
Only by arranging the cans in four rows, only the cans 52 for 100 spindles can be arranged, and the remaining cans 52 for 20 spindles need to be arranged in the fifth row as shown in FIG. If one row is 2
Even if the cans are arranged in a state where the number of the cans is six and the length is slightly longer than the length of the winding portion (length 13520 mm), the remaining 16 cans need to be arranged in the fifth row.

When the cans 52 are arranged in five rows, not only one extra feed roller 53 is required,
It is necessary to secure a space for arranging the cans 52 in the fifth row and for maintaining a predetermined distance from the cans 52 in the fourth row, and a large area is required for arranging the cans.

In the sliver splicing machine disclosed in Japanese Patent Laid-Open No. 2-91233, a spare full sliver can must be arranged side by side with a can to be spliced at the time of the sliver splicing work. As a result, if the number of supply sliver cans is large, a larger area is required for the cans arrangement.

When performing a sliver splicing operation with a sliver splicing machine, it is generally necessary to arrange the cans so that the sliver ends of full sliver cans are at predetermined positions. However, when the can is cylindrical, the can is easily rotated during the transportation from the kneading process to the roving process by the can transportation device, and the position of the end of the sliver in the transportation direction changes during the transportation. As a result, there is also a problem that the can 52 must be arranged so that the sliver end is located at a predetermined position before it is arranged behind the roving machine stand 51.

The present invention has been made in view of the above problems, and an object thereof is that, when a cylindrical can is used, the can array arranged behind the spinning machine stand is, for example, five rows. Even in a machine with a pitch pitch, the sliver with the same capacity can be supplied to all the weights in the space required for arranging the cylindrical cans in four rows, which is less than that, and the can transport path between the cans and the previous process. An object of the present invention is to provide a sliver supply method for a spinning machine that does not require an increase in the area of the sliver.

[0012]

In order to achieve the above object, in the invention according to claim 1, a case where cylindrical cans for accommodating a sliver are arranged behind the spinning machine stand along the longitudinal direction of the spinning machine stand. When the sliver is supplied to all the weights of the spinning frame in a container having substantially the same volume as that of the can, the width in the plane cross section is smaller than the diameter of the can, and the ratio of the width to the length is approximately 1: 4 to 5. The sliver housing part of the can whose volume is approximately twice that of the can is divided into two equal parts by partition walls extending in parallel with the longitudinal direction of the can, so that the longitudinal direction is the sliver spinning direction. Are arranged in two rows behind the spinning machine stand, and the number of sliver housings in each row is 1/2 of the total weight of the spinning machine stand, and the sliver in each sliver housing is arranged in each can row. Corresponding to the above It was to be supplied through the.

According to the second aspect of the present invention, the spinning machine stand is provided with a container having substantially the same volume as when the cylindrical cans for storing the sliver are arranged behind the spinning machine stand along the longitudinal direction of the spinning machine stand. In the case where the sliver is supplied to all the weights of the can, a can whose width in the plane cross section is smaller than the radius of the can and whose width-length ratio is approximately 1: 4 to 5 and whose volume is approximately equal to the can, Arrange the sliver in each can in two rows so that the longitudinal direction is the spinning direction of the sliver, and the number of cans in each row is 1/2 of the total weight of the spinning machine stand. The feed is provided via a feed roller arranged above the can row.

In this case, it is preferable that each of the cans is provided with a connecting means for connecting two adjacent cans so as to be integrally movable in parallel.

[0015]

In the invention described in claim 1, a can having a width-to-length ratio of approximately 1: 4 to 5 in the plane cross section behind the spinning machine base has a longitudinal direction thereof as the sliver spinning direction. Are arranged in two columns. The sliver is drawn out from each of the two sliver accommodating portions formed by dividing the can into two equal parts by a partition wall, and the sliver passes through feed rollers arranged above it corresponding to each of the can rows and then the sliver stands of the spinning machine stand. Supplied to the weight. Since the width of the sliver accommodating part is smaller than the radius of a normal cylindrical can, even if the number of cans corresponding to 1/2 of the total weight is arranged in one line in each line, the cylindrical cans are usually arranged in four lines. It fits in the can placement space.

Since there are two rows of sliver accommodating portions, the number of feed rollers can be two. In other words, the number of feed rollers is two in the case of the four-row arrangement and three in the case of the five-row arrangement. Also, if the sliver end of a full can is placed at a predetermined position, when the can is placed behind the spinning machine stand, the sliver end is placed at a predetermined position simply by aligning the front-back direction of the can. Work becomes easy.

Further, since the width of the can is smaller than the diameter of the conventional cylindrical can, the area of the carrying path for carrying the can with the previous process does not increase. Also in the invention described in claim 2, the arrangement space of all the cans is accommodated within the can arrangement space when the cylindrical cans are normally arranged in four rows. Further, the required number of feed rollers and the positional relationship of the sliver end portions are the same as in the first aspect of the invention. Further, since the width of the can is smaller than the radius of the conventional cylindrical can, the area of the transport path when transporting the can between the previous process is almost halved.

According to the third aspect of the present invention, by connecting two cans and carrying them integrally, an unstable state at the time of carrying due to the narrow width of one can is eliminated. .

[0019]

A device (not shown) is provided. The push-out device includes an air cylinder arranged along the longitudinal direction of the can conveying device 2a, 2b, and a locking member at the tip of its piston rod. The locking member is held at a position where it can be locked with the can 3 by a spring, and when the can 3 relatively moves from the base end side of the piston rod toward the locking member, a position that allows the can 3 to pass through. It is possible to evacuate to.

An extruding device 11c for pushing out the full sliver can 3F on the full can stocking device 4 on the side of the full can carrying device 5 at a position corresponding to the can loading side of the full can stocking unit 4 onto the full can stocking unit 4. Is provided. The pushing device 11c is also the pushing device 11a, 11b.
Similarly to the above, the full-can transporting device 5 is actuated when the full-can transporting device 5 is stopped based on a detection signal from a detection sensor (not shown).

On the unloading side of the full can stock portion 4, there is provided an extruding device (not shown) which is the same as the one arranged on the second end side of the can conveying devices 2a, 2b. An extruding device 11d is disposed on the side of the full can stock portion 4 at a position corresponding to the can loading side of the full can transport device 7. The pushing device 11d pushes the full sliver can 3F placed at a position corresponding to the full can conveying device 7 by the pushing device onto the full can conveying device 7.

The empty can transfer device 8 is constituted by connecting a plurality of transfer devices 8a whose transfer directions are different from each other by 90 degrees, and a can direction changing part 12 for changing the direction of the can 3 is connected to each transfer device 8a. Is provided. The can direction changing section 12 includes a turntable 12a, a sensor (not shown), and an extrusion device 12b. Then, the can direction changing section 12 changes the direction of the can 3 fed from the upstream side transport device 8a onto the turntable 12a by 90 degrees and sends it to the downstream side transport device 8a.

As shown in FIG. 1, a creel 13 is installed behind the roving machine base 1 so as to extend in a direction orthogonal to the longitudinal direction of the roving machine 1. The feed roller 14 is supported by the creel 13 in a state of extending along the longitudinal direction of the roving frame 1 above the feed roller 14 at approximately the center of each can row. Each feed roller 14 is provided with a sliver guide 15 corresponding to each can. The sliver guide 15 has a pair of truncated cone-shaped guide members connected to each other via a connecting portion having a diameter smaller than that of the small diameter portion with the small diameter portions facing each other. The sliver guide 15 is attached so as to be movable along the feed roller 14, and is fixed at a position where the path of the sliver S supplied from each can 3 to each weight 1a does not intersect.

As shown in FIG. 6, a traveling rail 16 is provided on the creel 13 above the sliver supply can row.
The bracket 1 extends along the feed roller 14.
It is supported through 7. The sliver splicer 18 is supported in a suspended state with respect to the traveling rail 16 via a bracket 20 equipped with a drive roller (not shown) and a driven roller 19, and is supported by a motor (not shown). It moves along the traveling rail 16 by reverse rotation. The sliver splicing machine 18 includes a sliver piecing unit, a sliver presser, a sliver cutting device (none of which are shown), a sliver gripping arm 21, and the like, and connects the sliver S hanging from the feed roller 14 and the sliver S of the full sliver can 3F.

The traveling rail 16 is formed longer than the feed roller 14. The sliver splicing machine 18 is shared by a plurality of roving machine bases 1, and a carrier (not shown) that moves along the side of the roving machine base 1 requires work. It is designed to be transported to the end of 16.

Since the kneading machine 6 accommodates the sliver S uniformly in the can 3 having a rectangular cross section, the can supporting device (not shown) arranged below the tube wheel of the coiler device has the can 3. It is configured to be reciprocally movable in the longitudinal direction. This configuration is, for example, Japanese Patent Publication No. 35-8122.
It is disclosed in the publication. As shown in FIG. 7, the tube wheel 22 is formed such that the coil diameter of the sliver fed by its rotation is substantially equal to the width of the can 3. Further, the can support device is arranged on a support plate (not shown) which can be raised and lowered.

In the coiler device of the drawing machine 6, when the tube wheel 22 is stopped, the sliver outlet of the tube wheel 22 is stopped at a predetermined position near the first end of the can 3. Further, the drawing machine 6 is equipped with a sliver end restricting device (not shown) having basically the same structure as the sliver end restricting device disclosed in JP-A-3-293267. The sliver gripping arm and the sliver guide arm of the sliver end regulation device cause the sliver end to hang down to a predetermined position outside one end of the can 3 in the longitudinal direction when the sliver S is completely stored.

Next, the operation of the device configured as described above will be described. First, the operation of the drawing machine will be described. The can 3 conveyed to the drawing machine 6 accommodates a predetermined amount of sliver S by the coiler device of the drawing machine 6. Can 3
The lifting plate is held in the raised position while the sliver is being supplied to the lifting plate. In this state, the coiler device is operated, and the sliver S is sent out from the tube wheel 22 into the can 3 while the can 3 is reciprocally moved in the longitudinal direction. Then, as shown in FIG. 8, they are housed in a coil shape. When the can 3 is full, the support plate is lowered to a position where the bottom of the can 3 corresponds to the can transport device 5. Then, the sliver end regulating device is actuated, and the sliver end portion is arranged so as to hang down at a predetermined position outside one end in the longitudinal direction of the can 3. Then, the can 3 is extruded onto the full can conveying device 5 by a can extruding device (not shown) provided on the side of the kneading machine 6.

The full sliver cans 3F transferred onto the full can stocking device 5 are carried to a position corresponding to the full can stock part 4 and transferred onto the full can stock part 4 by the pushing device 11c. Assuming that the side where the sliver end SE of the full sliver can 3F hangs is the rear side, the full sliver can 3F transferred from the kneading machine 6 onto the full can conveying device 5 is conveyed backward by the full can conveying device 5. Then, the direction of the full sliver can 3F is transferred to the full can stock unit 4 by the lateral movement without being changed.

The full sliver cans 3F are laterally conveyed in the full cans stocking section 4, and the full sliver cans 3F stocked in the full cans stocking section 4 are fed forward one by one onto the full cans conveying device 7. Then, it is conveyed forward by the full can conveying device 7 and pushed out by the pushing device 11.
By the action of a and 11b, the full sliver can 3F is laterally transferred and placed on the can conveying devices 2a and 2b which require the sliver can 3F. Then, the cans 3 adjacent to the predetermined positions on the can conveying devices 2a and 2b are arranged in a state of being in contact with each other. As a result, unlike the case of the cylindrical can, even if the position of the sliver end SE is not detected and the orientation of the full sliver can 3F is not corrected, the sliver end SE is automatically set to a predetermined position on the rear side of the full sliver can 3F. Full sliver cans 3F are arranged in a line in a state of hanging down to the position.

Each roving machine base 1 has three cans 3 in front and rear rows.
The sliver S is supplied from. Since Kens 3 has 2 rows,
The number of feed rollers 14 is also improved to two. Therefore,
If the conventional cylindrical can is arranged in five rows, the number of feed rollers 14 is five, and the can conveying device is also five rows, the structure of the entire apparatus is simple and the manufacturing cost is low. Further, when the sliver splicing work is performed by the sliver splicing machine 18 that moves on the traveling rail 16 that is installed above the can row, the number of traveling rails 16 is reduced and the manufacturing cost is reduced.

Further, the space required for arranging the cans 3 becomes narrower, and the distance from the roving machine stand 1 to the cans 3 in the rear row becomes shorter. Therefore, the distance until the sliver S supplied from the rear row reaches the weight 1a is shorter than that in the case of five rows, and the possibility of the false draft of the sliver S is reduced, and the product (spun roving) is reduced. Improve the quality of.

When the sliver S is consumed and the can 3 approaches the sky, the operation of the roving machine stand 1 is stopped, and the sliver splicing work and the can replacement work are performed. First, the sliver splicer 18 moves forward along the traveling rail 16 to perform the sliver cutting work. The sliver S is suspended from the feed roller 14 as shown in FIG. Next, the can replacement work is performed.

The can replacement work will be described by taking the rear row as an example. During the can replacement work, the full sliver cans 3F on the full can transfer device 7 are fed one by one onto the can transfer device 2b by the action of the pushing device 11b as described above. When the full sliver can 3F is pushed onto the can conveying device 2b, the can row on the can conveying device 2b is pushed to the second end side of the can conveying device 2b via the full sliver can 3F, and the end on the second end side is pushed. The empty can 3 is moved to a position where it can be engaged with the pushing device. The empty can 3 is transferred onto the empty can transfer device 8 by the pushing device.
The empty can 3 transferred onto the empty can transfer device 8 is transferred to the kneading machine 6 by the empty can transfer device 8. The direction of the empty can 3 is changed by the can direction changing section 12,
It is conveyed while always moving along the longitudinal direction.

When the number of full sliver cans 3F for one row is sent out, the delivery from the full can stocker 4 is completed. Further, the number of times of operation of the pushing device 11b is counted by the counter, and after the pushing device 11b completes the pushing operation for the number of one row, the operation of the full-can transporting device 7 is stopped. The full sliver cans 3F sent from the kneading machine 6 by the time of the next can replacement are sequentially transferred onto the full can stock part 4 and arranged in a line as described above.

When the can replacement is completed, the sliver splicing machine 18 starts moving from the standby position in the opposite direction to the sliver cutting work, and intermittently stops at a predetermined position corresponding to the sliver S to successively perform the sliver splicing work. . Since the sliver end portion SE of the full sliver can 3F hangs down to a predetermined position on the rear side of the can 3, the sliver end portion SE can be easily and surely gripped by the sliver gripping arm 21, and the sliver splicing work can be performed smoothly.

In this embodiment, since the width W of the can 3 is smaller than half the diameter of the conventional cylindrical can, the empty can transfer device 8 and the full can transfer for transferring the can to and from the drawing machine 6. The installation area of the devices 5 and 7 is almost halved. As a result, the degree of freedom in layout is increased.

The present invention is not limited to the above embodiment, but may be embodied as follows, for example. (1) The number of spindles of the roving machine base 1 is not limited to 120 spindles, and the spindle pitch is not limited to 110 mm. For example, in the case of 96 weights, if four rows of cylindrical cans are arranged, one row has 24 rows. If the weight pitch is 130 mm, there is no problem in arranging 24 cylindrical cans in one row, but if the weight pitch is 110 mm, only 20 cylindrical cans can be arranged in one row, and five row arrangements are required. Also, even if the weight pitch is 120 mm, it is 520 mm.
It is difficult to arrange the cylindrical cans in 4 rows, but it becomes 5 rows. However, by using the can 3 of the above-mentioned embodiment, the arrangement in 2 rows is sufficient, and the same effect as that of the embodiment can be obtained. Also, Ken 3
The width W and the length L are not limited to the values in the above embodiment,
The number may be appropriately changed as long as the number of the cans 3 can be arranged without any trouble. Further, the can 3 is not limited to the rectangular tube shape, and may have a shape in which both end portions in the longitudinal direction are chamfered, or an oval-shaped plane having arcuate surfaces on both sides in the longitudinal direction.

Needless to say, the can 3 of the above embodiment may be used even when the conventional cylindrical can can be arranged in four rows. Even in this case, as compared with the case where the cylindrical can is used, the sliver end portion can be easily arranged at a predetermined position, and the installation areas of the full can transfer devices 5 and 7 and the empty can transfer device 8 are reduced, and There is an advantage that the numbers of the rollers 14 and the can conveying devices 2a and 2b are reduced.

(2) The cans 3 do not necessarily have to be arranged in contact with each other, and in particular, when the cans whose total width is ½ of the total weight are arranged in one row due to the weight pitch. If the length is larger than the length, the cells may be arranged at appropriate intervals.

(3) The can 3 is not limited to the one having the receiving plate 3b supported by the coil spring 3b, but the can 3
It is also possible to provide guide holes extending in the up-down direction on both front and rear sides, and provide hooking portions projecting from the guide holes on both sides of the receiving plate 3b so as to be movable up and down along the guide holes. In this case, the receiving plate 3b is always arranged at the bottom of the can 3.
Then, the kneading machine 6 is provided with an elevating mechanism which engages with the hooking portion of the receiving plate 3b to elevate and lower the receiving plate 3b, and when the sliver S is accommodated in the can 3 by the kneading machine 6, the receiving plate 3b is held. It is gradually lowered from the ascended position and stored. As an elevating mechanism, for example, there is one in which a hook is attached to a chain that is reciprocally driven, such as the device disclosed in Japanese Patent Laid-Open No. 50-123941.

(4) Width W twice that of the can 3 of the above embodiment
The inside of the can 3D having two parts is divided into two equal parts by a partition wall 23 extending parallel to the longitudinal direction of the can 3D, and two sliver accommodating parts 24 are provided.
A can 3D provided with a and 24b may be used. In this case, the number of cans 3D in one row is 1/4 of the total weight, but the total number of sliver housing portions 24a and 24b is 1 of the total weight.
/ 2. The receiving plates are independently supported by the coil springs (neither shown) in the accommodating portions 24a and 24b. Then, each sliver housing portion 24
The sliver accommodated in a and 24b is simultaneously supplied to each weight 1a via the feed roller 14 and the sliver guide 15.

Also in this case, the arrangement space of the can rows and the structure of the creel section are the same as those in the above-mentioned embodiment. Also, Ken 3
The moving direction of the can 3D when D is conveyed is also the same as that in the above embodiment. Since the width W of the can 3D is twice that of the can 3, the widths of the full-can transport devices 5 and 7 and the empty can transport device 8 are twice as wide as those in the above-described embodiment. However, even if the width W doubles, it is smaller than the diameter of the cylindrical can, so that the area required for installing the full-can transport devices 5 and 7 and the empty can transport device 8 is almost the same as the conventional one.

Further, in this case, the width W of the can 3D becomes wider, so that the stability at the time of conveyance is improved as compared with the can 3 of the above-mentioned embodiment. Further, in this case, each can transport device 2a, 2
Number of cans 3D arranged in b and one roving machine base 1
Therefore, the number of cans 3D required is 1/2 of that in the above-described embodiment, so that the operating frequency of each of the extrusion devices 11a to 11d, the full-cans conveyors 5 and 7, and the empty cans conveyor 8 is also 1/2. Therefore, the service life of each device is extended.

When this can 3D is used, when the sliver S is accommodated by the kneading machine 6, as shown in FIG. The can 3D is arranged at a position corresponding to the tube wheel 22. In that state, the sliver S is accommodated in the sliver accommodating portion 24a while the can 3D is reciprocally moved in the width direction in the same manner as described above. When the accommodation of the sliver S in the accommodation portion 24a is completed, the can 3D is moved in the direction of the arrow A, and the sliver accommodation portion 24b is moved to the tube wheel 22.
Is placed at a position corresponding to. Then, in this state, the coiler device is operated again to store the sliver S in the sliver storage portion 24b.

(5) A can 3 having a narrow width W as in the embodiment.
In addition, a connecting means may be provided to connect two adjacent ones in parallel so as to be integrally movable. The connecting means is, for example, a hook provided on at least one of the front and rear surfaces of each can 3,
And a hook portion hooked on the hook. Alternatively, a magnet 25 (shown by a chain line in FIG. 3) fixed to one side wall extending in the longitudinal direction of the can 3 may be used as the connecting means. In this case, the cans 3 are provided in two types, one in which the N pole of the magnet 25 is fixed on the outer side and the other in which the S pole is fixed on the outer side. Use in facing state. Then, usually, a pair of two sliver accommodating portions 24a, 24b is used in the same manner as the can 3D. In that case,
The same action and effect as when using the can 3D is exhibited.

If a space similar to the conventional one cannot be secured as the installation space for the full can transporting devices 5 and 7 and the empty can transporting device 8, the cans are transported individually one by one as in the can 3 of the above embodiment. Used in the state. As a result, the same can 3 can play the role of two types of cans, and the manufacturing cost can be reduced. When the magnets are used as the connecting means, it is preferable that the magnets are detachably fixed to the cans 3, and when the cans 3 are individually transported, the magnets are preferably removed and used.
If the magnets are removed and used, it is not necessary to pay attention to the direction of the can 3 so that magnets having different magnetic poles do not face each other.

(6) A roller conveyor provided with a large number of rollers that are positively driven may be used as the full can stock unit 4, the full can transfer devices 5, 7 and the empty can transfer device 8. Further, a roller conveyor having a large number of rollers that are positively driven may be used for the can conveying devices 2a and 2b.

(7) Depending on the production capacity of the drawing machine 6, a plurality of full can stock parts 4 may be provided. Alternatively, the full sliver cans 3F may be arranged in the full can stock part 4 so as to form one row in the longitudinal direction. In this case, it is preferable to stock the required number of full sliver cans 3F in the can transfer devices 2a and 2b in a plurality of lines instead of stocking them in the one line full can stock unit 4. Further, since the can replacement time of the roving machine stand 1 is known in advance, the can transfer device 2 that requires the next can replacement before the can replacement time comes.
The full sliver can 3F may be arranged on the full can conveying device 7 on the upstream side of the positions corresponding to a and 2b.
In this case, the time required for can replacement can be shortened, the stop time of the roving frame 1 can be shortened, and as a result, the operating rate of the roving frame can be improved.

(8) First of each can conveying device 2a, 2b
Instead of arranging the pushing devices 11a and 11b at positions corresponding to the ends, like the device disclosed in Japanese Patent Laid-Open No. 3-293267, the can moving device moves along the full-can transport device 7 to move each can transport device. It is also possible to provide a carry-in device that stops at the first ends of the cans 2a and 2b and carries in the full sliver can 3F on the full can conveyer 7 onto the can conveyers 2a and 2b.

(9) The sliver guide 15 is not limited to the one in the above embodiment, and a sliver guide whose tip is expanded in a V shape may be attached to a support rod provided in parallel with the feed roller 14. .

(10) The sliver splicing work may be performed manually, or the operator may carry out the can transfer between the drawing device 6 and the can transfer devices 2a and 2b. (11) It may be applied to spinning machines other than the roving spinning machine.

[0062]

As described above in detail, according to the present invention, even in a machine stand having a weight pitch such that the cans arranged in the rear of the spinning machine stand are, for example, five rows when a cylindrical can is used, The sliver of the same capacity can be supplied to all the weights in the space required for arranging the cylindrical cans in four rows less than that, and it is necessary to increase the installation area of the transfer device necessary for transferring the cans to the previous process. There is no. In addition, the number of feed rollers and the number of can transporting devices constituting the creel unit is reduced to less than half, and the manufacturing cost is reduced.

Further, in addition to the above effects, in the invention described in claim 2, the installation area of the transfer device required for the transfer of the cans between the preceding steps is almost half, and the degree of freedom of layout is increased. In the invention according to claim 3, even if the can has a narrow width and is poor in stability during transportation, by using two cans connected in the width direction, instability during transportation can be eliminated.
