Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides an automatic splicing method for automatically transporting combed wrap to items in a group of combs that require wrap replenishment and at the same time performing automatic splicing. It relates to the apparatus used to carry out the method.

(Prior Art) Conventionally, as an automatic wrap conveying device in the combing process of cotton spinning, a pair of running rails connecting the wrap former and the upper part of the comber group is bridged, and the combed wrap is transferred to a running body running along the running rails. Attach the hanging grip hanger,
A plurality of wraps (generally 6 or 8 wraps) produced by a wrap former and arranged to match the comber head spacing are lifted simultaneously, and the comber is automatically moved in response to a request from the comber. A device for conveying onto the preliminary lap stand is provided, and as such a conveying device
As disclosed in Japanese Patent No. 5-21068 and the like (known in the art).

By the way, in the past, the conveyance device only had the function of automatically conveying the combed wrap to the wrap placing table of each comb,
When the final unrolling is near, the comber is temporarily stopped, the wrap with a small amount of lap fleece is moved from the wrap unwinding section, and the full combed wrap mounted on the wrap table for replenishment is manually placed on the wrap unwinding section. After the repairs were made, the fleece was lap-spliced, and this lap-splicing was done manually by a machine operator.

(Problem to be solved by the invention) Automatic splicing of wrap fleece in the combing process is a long-standing problem that has always been desired in the industry in order to streamline the process and promote the shift to highly controlled work by drivers. Therefore, some attempts have been made to install this type of equipment on the comber group side, but recently the number of combers in spinning factories has increased to several dozen due to productivity reasons. It also extends to
And since 8-delivery coma has been frequently used recently,
The number of automatic wrap fleece splicing devices is 8 times the number of combers, which poses a problem that causes a huge increase in equipment costs.

On the other hand, it has been proposed to use one automatic splicing device for 8 deliveries as a moving structure for a group of combers, but in this case as well, a control system is required in addition to a guide device such as a traveling rail to move it. Not only does it have a complicated structure because it intersects with the automatic wrap conveyor, but it also requires proper timing between both devices, making it difficult to control, and it has many problems as a practical device. are doing.

In view of the current situation, the present invention is an automatic wrap conveying device with an integrated structure that adds an automatic wrap/pipe splicing function, since the replenishment of wraps and the splicing of wraps are performed at the same location and at different timings.

The above-mentioned lap hanging mechanism (21, (2)
and spool support mechanisms (3), (3) are installed vertically, and air nozzles (41, 41,
(4) is installed, but this air nozzle (4),
(4) can also be provided on the first elevator frame (8) side.

First, the wrap suspension mechanism (2) will be explained with reference to FIGS. 1 and 2. It is arranged so as to extend in the longitudinal direction of the center of the machine frame (8), and both ends are rotatable via bearings. The rotary shaft (2) supported by the shaft and the first elevator frame (8)
A state in which six pairs of hooks αa... are suspended in relation to six fixed shafts arranged and supported at equal intervals across the width of the machine. It is installed with.

Fixed shaft α at the base of the shoulder which is the upper end of each hook αa and α
It has a hole into which hot water can be inserted loosely, and a backing plate whose shoulder part can be pressed from below to the cam fixed to the rotating shaft (b), and the hook part serving as the lower end support part is rotated. In the axial direction of the shaft (B), the pair of hooks Q4) and Q4) are arranged symmetrically so as to face each other, and the upper end portion is fitted into the 0th floor of the fixed shaft.

A pair of springs αη and α force are wound around each fixed shaft αω, one end of which is fixed to the machine frame (8), and the other end is hooked to a hook α.

A spring α is connected to the shoulder base of αO, and gives αD a restoring force that always tends to open the pair of hooks in a direction in which the lower end support parts move away from each other.

On the other hand, a rotating shaft (2) having 12 cams a9 fixedly attached to each hook α4), Q4) has a gear fitted to one end, and this gear and the first elevator frame (8) A gear fitted to the output shaft of a motor 00 fixed to the motor 00 is connected in a chain, so that the motor a0 can be driven in forward and reverse rotation.

The lap hanging mechanism (2), (21) configured as described above has a pair of hooks α, α, whose hook tips of the lower end support portion face each other in the longitudinal direction of the machine frame (8), and Each pair is arranged horizontally in a row in the same longitudinal direction, and when the motor αω is rotated in the forward direction to rotate the rotating shaft (2), the cams α9 and α9 of each pair rotate at the same time. The shoulders of hooks aa and αω are brought into sliding contact with the circumferential surfaces of cams QS and α9 due to the restoring forces of springs 0η and αη.
The α ships gradually open their lower end supports in a direction that moves them away from each other.

On the other hand, when the motor aQ is reversely rotated to rotate the cam α and αω by half a rotation, the shoulders of the hooks (14) and (14) are moved by the spring α.
Since it moves downward against the restoring forces of η and aη, the lower end support portions gradually close in the direction of approaching each other,
Thus, by the forward and reverse rotation of the motor 00, the hook αtortoise α~
The opening and closing of the combed wrap (6
) can be inserted into both ends of the spool (7) so as to sandwich it from both sides in the axial direction, and can be supported in a suspended state, and can also be released from support.

Next, the spool support mechanism (3) will be explained with reference to FIGS. 1 to 6.

A first rotation shaft (23) and a second rotation shaft (25), which are parallel to each other, are rotatably supported on the second elevator frame (9) having a rectangular cylindrical shape. The shaft (23) is attached to the machine frame (9
) is extended in the longitudinal direction and supported by a plurality of bearing members (24), while the second rotating shaft (
25) is extended to a position immediately below the first rotating shaft (23) by a plurality of brackets (26) fixed to the side plate of the machine frame (9).

The first rotating shaft (23) has a total of 12 gripping arms 11201.6 in pairs on the left and right that correspond to the hooks α4) and Q4). Ql screws the nut part (27) at the upper end into the male screw part formed on the first rotating shaft (23), and loosely inserts the vertical part into the long hole (28) provided in the bottom plate of the machine frame (9). It is pushed through and installed vertically, while the second rotating shaft (2

5) is rotatably installed vertically around.

As shown in detail in FIGS. 5 and 6, the pair of left and right gripping arms t20) and (2m) have a shape in which the vertical part and the curved part are connected to each other, and the upper end of the vertical part has the aforementioned shape. One arm 12 has a nut portion (27) that
is screwed into the right-hand male thread provided on the first rotation axis 3),
The other arm 12 is similarly screwed into the left male threaded portion and vertically disposed in a symmetrical arrangement.

The first rotating shaft (23) has a gear (2
9), and this gear (29) is attached to the machine frame (9).
) is connected to the gear (31) fitted to the output shaft of the motor (30), and the motor (30) is connected by a chain.
0) in the forward and reverse directions and the first rotating shaft (23) in the forward and reverse directions, a pair of gripping arms eΦ1 (
The 2Φ move horizontally toward or away from each other, and six of them approach and move away at the same time.

Therefore, at the curved lower end portion of each gripping arm (2, I2m), a roller αω is attached to the opposite arm (2Φ
The shafts (32) are rotatably fitted to shafts (32) that protrude horizontally from the opposite surface.

As for the roller 0 mentioned above, the illustrated example uses a flanged type roller, but it is also possible to use a roller without a flanged type.Furthermore, in the illustrated embodiment, an auxiliary roller (33) is attached in addition to the roller αω. It has a structure of a pair of rollers arranged side by side and two on each side on the left and right, and works together with the drive roller α1, which will be described later, to pinch the ends of the combed wrap (6) from both the inside and outside. When supported, it has the advantage of being able to be stably supported by adopting a three-pronged support system, but even with one each on the left and right sides of the old Colo 0, the purpose can be sufficiently achieved.

On the other hand, a pair of arms (21), which are rotatably supported by the second rotating shaft (25) and arranged symmetrically, are located at the lower end of both ends sandwiching the fulcrum. A bearing part having a ball bearing (not shown) fitted therein is provided respectively, and a protrusion (34) is provided at the upper end of one arm (21), so that the pair of arms (21), (21) A drive roller 09) having a rotating shaft integrally extending between the bearing parts of the drive roller 09)

One end of a spring (36) is locked to the upper end of the arm (21) on which the arm (21) is not provided.

The other end of the spring (36) is locked to an appropriate position on the upper part of the bracket (26), and the elastic force of each arm (2
The protrusion (3) is actuated to stand upright in the vertical direction, and the protrusion (3)

35), further swinging is suppressed.

Therefore, as shown in FIG.
and horizontally installed above the auxiliary rollers (33) in a three-pronged manner, and the springs (36) constantly apply an elastic force in the direction of approaching both rollers α8) and (33). The position is determined by (35).

A gear (37) is fitted onto the shaft of each drive roller α$ which is imparted with elastic force in this way.
7) is connected to a gear (39) fitted to the second rotating shaft (25) via an idle gear (38) rotatably attached to the arm (21), and the second rotating shaft (25) When rotation is applied to , the six drive rollers α (to) and αω are rotated all at once in the same direction.

In addition, (22) is a rotational drive source, for example, a deceleration motor, which is fixed to the second elevator frame (9) with its shaft parallel to the second rotating shaft (25), and is fitted onto the shaft. Gear (4
0) is connected to a gear (41) fitted to a second rotating shaft (25), and by rotation of the motor (22), it is possible to positively rotate each of the drive rollers α9 all at once.

The spool support mechanism (3) having the above-described structure is configured such that each pair of gripping arms QΦ, I2Φ is separated from each other by the reverse rotation of the motor (30) until they are far away from each other. The heavy telescopic tubes Cl0) and αQ are synchronously extended to lower the second elevator frame (9), and the drive roller αΦ is located at the lower combed wrap (6)', that is, at the wrap delivery portion αυ. Near the final unrolling, the wrap fleece comes into contact with the upper surface of the wrap (6)' with only a few remaining turns, and the spring (
arm (21) against the elastic force of 36).

(21) is stopped at a position where the drive roller α9 side is extended and moved upward, and then the motor (30) is rotated in the forward direction to move each pair of gripping arms (2 and ta in the direction toward each other). The auxiliary roller (33) is the spool (7) of the combed wrap (6).
The second elevator frame (9) is stopped at the same time as the motor (30) is stopped when the flanges of the rollers inserted from both sides touch the end of the spool (7)'. By raising it, as shown in Figures 4 and 6, the roller becomes zero.

The combed wrap (6) can be supported and lifted by the auxiliary roller (33) and the drive roller Ql.

Further rotate the motor (22) and drive roller α□□□
When rotation is applied to the combed wrap (6)', it is possible to rotate the wrap fleece in a direction to tighten it while supporting the combed wrap (6)'.

Next, to explain the air nozzle (4), structural examples are shown in Figs. 1, 2, and 4, and the manifold pipe (42) installed along the second elevator frame (9)
and a blower (43) fixed to the machine frame (9) in order to send pressurized air into the pipe (42), an air nozzle (4) is provided. 4) is the lap hanging mechanism (2).

(2) and the spool support mechanism (31, (3)), the manifold pipe (42) is equally divided in the longitudinal direction, and six slit-shaped outlets are cut in the diagonally downward outer circumference in the illustrated example. The air curtain-like pressurized air is directed toward the outer circumferential axis of the combed wrap (6) placed on the wrap delivery parts (11), (11) with the blowing direction directed diagonally backward. It can be sprayed on.

A method for automatically splicing using the embodiment apparatus described above will be described below with reference to FIGS. 1 to 8 and each of the figures from FIG. 9 onwards.

As is clear from the above description, by moving the movable frame (1) to the wrap feeding part of the wrap former, lowering the first elevator frame (8), and rotating the motor α0 semi-reversely, the pair of hook Q41. Use α0 to load the fully wound replenishment combed wrap (6)/knob hanging mechanism (2)
After suspending and supporting the six pieces at once in step (2), the machine frame (8) is raised (referred to as wrap support means).

The movable frame (1) is moved by a wrap splicing signal transmitted from the comb group side, and the comb group is connected.

The lap feeding part (11) of the comb where the wrap (6)' is nearing the final feeding leaving about several turns after feeding.
, (11) to guide the movable frame (1) and keep it in a standby state.

This operation corresponds to the wrap conveying means until the state shown in FIG. 9 is reached.

Next, as the comber stops for lap splicing, the second elevator frame (9) is lowered, and the pair of rollers α and α and auxiliary rollers (33) and (33) are brought closer together. , by pushing up by the contact of the drive roller α (
As is clear from the above explanation, the rollers Q8) and (33) are inserted into the spool (7) and the second elevator frame (9) is slightly raised. Then, the spool (7)' of the combed wrap (6)' is floated from the wrap delivery part αυ while being supported by three lines (see Fig. 11).

This operation corresponds to the spool support means shown in FIGS. 10 and 11.

Next, the movable frame (1) is moved by a slight pitch in the forward direction, and then the second lifting machine is moved so that the comb wrap (6)' approaches the comb payout rollers (60) and (61) as much as possible. Lower the frame (9). In this state, the spool (7)' has 8 parts αD, αυ
The wrap fleece feeding side of the spool (7)' is positioned in front of the feeding rollers (60), (61) and almost perpendicularly to the wrap i mulberry feeding line of the feeding rollers (60), (61), and the spool (7) Take the shortest distance between '' and the feed line.

Thereafter, the drive roller 0'8A is driven in the direction opposite to the direction in which the wrap is fed out, and the wrap fleece is draft cut. (Illustrations omitted) Next, the wrap hanging mechanism (2) moves the movable frame (1) until the axis of +21 is directly above the center of the wrap feeding part αυ, lowers the first lifting frame (8), and lowers the pair of hooks. A lap suspension mechanism (2) that performs a separation action on the α-ring α ship, (
Turn the full wrap supported by 2) and place it on section 8 0D.

The series of operations described above corresponds to the lap cutting and changing means shown in FIG.

After that, pressurized air is blown diagonally downward and backward from the air nozzle (41, (4)) in the form of an air curtain, and the pressurized air is applied to the winding end of the combed wrap (6) placed on the wrap delivery parts 0D and αD. The starting end of the wrap fleece is peeled off with pressurized air and hangs downward, along with the fleece guide (56) of the wrap unwinding part αυ.

In addition, the combed wrap (6) is placed on the lap former side so that the winding end position of the combed wrap (6) can definitely hit the air blown out from the air nozzle f4) and +41.
It is preferable to align the postures of the air nozzles f41. (In order to correctly set 41 in the predetermined position, it is sufficient to lift and lower the second elevator frame (9) from the state shown in FIG. 12.

After confirming that the wrap fleece has dripped down along the fleece guide (56), when the comb is fed out at the wrap feed section 0υ, the tip of the wrap fleece on the replenishing side and the wrap fleece on the take-out side are aligned. The parts are sent out overlapping each other.

In this way, unnecessary fleece is cut and automatically spliced by overlapping.

The operation described above corresponds to the automatic lap joining means shown in FIG.

In this way, the spool (7) leaving a short fleece remains supported by the spool support mechanisms (3), (3), and causes the mechanisms (3), (3) to move horizontally, move up and down, and release the support. The spool can be transferred to a predetermined spool storage section.

(Effects of the Invention) The present invention provides a wrap hanging mechanism (21, (21) and a movable spool support mechanism (31, +31) for supporting and transferring the replenishing combed wrap (6), and both mechanisms! (2)..., (31, (3)...) can be moved up and down and released from support separately, and an air nozzle (4) that peels off and hangs the end of the wrapped fleece using air pressure.

(4) above both mechanisms +21. (2), (3), (3
), starting from the standby position for supply and transfer, both mechanisms (2), (2), (
3), a unit structure device attached to the movable frame (11) by simple sequence operations related to raising and lowering f3), supporting/releasing, pinch movement, reverse rotation or braking of the drive roller αω, and jet operation of the air nozzle (4). Wrap replacement, automatic splicing, and spool retrieval can be performed consistently and accurately with just a single tap.

Furthermore, since this device can be used in common with many combers, it can be configured compactly.
3) and the air nozzle (4), conveyance and splicing can be carried out automatically and rationally.

In this way, in the combing process, guide mechanisms such as rails are required separately.
Since it is only necessary to add a few mechanisms to the movable frame (1) without adding any additional equipment, it is excellent as a practical device because it has a simple structure but can exhibit multiple functions. Furthermore, by implementing the present invention, the wrap mounting table on the combed group side is omitted, making effective use of space, and on the other hand, the work of joining the laps is eliminated.
This allows the driver to concentrate on other high-level management tasks.
