Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides an automatic splicing method for automatically transporting comb laps to items in a group of combs that require lap 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 lap transport device in the combing process of cotton spinning, a pair of running rails connecting a lap former and the upper part of a group of combers is bridged, and the combing wrap is hung on a running body that runs along the running rails. A lower grip hanger is attached to simultaneously lift multiple laps (generally 6 or 8 laps) produced by the wrap former and arranged to match the head spacing of the comber, and according to requests from the comber side. A device is provided for automatically conveying the comber onto a pre-lap stand, and such a conveying device is well known as disclosed in Japanese Utility Model Publication No. 45-21068.

By the way, in the past, the conveying device only had the function of automatically transporting the combed wraps to the lap placing table of each comb, and when the final unwinding was near, the combers were stopped and the laps with a small amount of wrap fleece were removed from the wrap unwinding section. At the same time as the fleece is being moved, the fully wrapped combed wrap mounted on the wrap table for replenishment is manually placed on the wrap feeding section, and then the fleece is spliced, and this lap splicing is done manually by the machine operator. It was done by asking for it.

(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 this industry in order to streamline the process and promote the shift to highly controlled work for drivers. Although some attempts have been made to install this type of equipment on the comber group side, the number of combers in recent spinning factories has increased to several dozen due to productivity reasons. In addition, 8-delivery coma is often used recently,
The number of wrap fleece automatic splicing devices is the number of combs x
There is a problem in that the number of units is 8, resulting in a huge increase in equipment costs.

On the other hand, it has been proposed to use one of the automatic splicing devices for 8 deliveries as a moving structure for a group of combs, 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 lap automatic conveyance device, but it also becomes complicated in terms of control because the timing between both devices must be adjusted appropriately, and it has many problems as a practical device. ing.

In view of the current situation, the present invention is an apparatus with an integrated structure that adds an automatic lap splicing function to an automatic lap conveyor, since the replenishment of laps and the lap splicing are performed at the same place and at different timings. By doing so, the waiting of the replenishment lap and the overlapping splicing of the end of the wrap fleece rewound by the comb and the tip of the fleece of the replenishment lap can be easily and reliably performed in a properly timed and sequential operation. The purpose is to promote automation and improve advanced work management by saving driver labor.

(Example) Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show the main structure of the entire device of the embodiment, and FIGS. 3 to 8 show the detailed structure of each part of the device. Consisting of six lap hanging mechanisms 2, 2..., the same number of spool support mechanisms 3, 3..., and the same number of air nozzles 4, 4..., both mechanisms 2, 2..., 3, 3... ...and air nozzles 4, 4...
... are attached to the movable frame 1 so that they can run integrally.

The movable frame 1 has four wheels, two front wheels and two rear wheels, with respect to a pair of running rails 5, 5 extending parallel to each other.
The above-mentioned rolling wheels 57, 57 are mounted, and are bridged between the wrap supply section of a comber preparation machine (not shown) and the upper part of a comb group in a combing process in which a large number of 6-delivery type combers are arranged side by side. It is guided by traveling rails 5, 5, and is movably formed directly above each comb and to the lap supply section. Since this traveling drive mechanism is a well-known one, its explanation will be omitted. .

In each figure, numeral 6 indicates a comb wrap wound around the spool 7.

A first lifting machine frame 8 is connected to the movable frame 1 via a hanging member such as a steel wire, and a second lifting machine frame 9 is connected to the movable frame 1 via a hanging member such as a triple telescoping tube 10. It is suspended so that it can be raised and lowered in the vertical direction while maintaining horizontality, and in the illustrated example, the first lifting machine frame 8 is located at the rear, and the second lifting machine frame 9 is at the front, and both machine frames 8 and 9 are provided parallel to each other so that their longitudinal directions intersect at right angles to the direction in which the movable frame 1 moves forward and backward.

Although a mechanism for raising and lowering the first elevator frame 8 is not shown, it can be raised and lowered by winding the steel wire 44 around a winding drum and rotating the drum in forward and reverse directions.

On the other hand, the main parts of the mechanism for raising and lowering the second elevator frame 9 are shown in FIGS. 7 and 8, and the thin rod 50, the intermediate cylinder 51, and the thick cylinder 52 are fitted in order, Slide bearings 53, 53' at each fitting part
The lower end of the thin rod 50 is fixed to the second elevator frame 9 using the triple telescoping tube 10 with the , a chain 54, which has one end locked to the upper end of the thin rod 50 and is inserted into the intermediate cylinder 51 and the thick cylinder 52, is engaged with the sprocket 46 which is rotatably fitted on the shaft 45 of the movable frame 1; The other end of the sprocket 46 is locked at an appropriate position on the sprocket 46, and when the sprocket 46 is rotated by the brake motor 47 until the chain 54 is engaged with nearly one turn, the second elevator frame 9 is rotated. It rises and reaches its limit, and when rotated in the opposite direction, it descends and reaches its lowering limit in a state of minimum engagement.By synchronously operating the same mechanisms located on the left and right sides, the system can be leveled. It can be held and moved up and down vertically.

In addition, a drive device consisting of a reducer 48 and a brake motor 47 is connected to one end of the shaft 45, and an electromagnetic brake 49 is connected to the other end, so that the shaft 45 can be moved up and down and stopped by sudden braking. By synchronously winding or unwinding the pair of chains 44, 44, the second elevator frame 9 can be held horizontally and moved up and down.

The above-mentioned lap hanging mechanisms 2, 2 and spool support mechanisms 3, 3 are respectively vertically disposed on the first lifting machine frame 8 and the second lifting machine frame 9 having the above-described structure, and the second lifting machine Although the air nozzles 4, 4 are attached to the frame 9, the air nozzles 4, 4 can also be provided on the first elevator frame 8 side.

First, the lap suspension mechanism 2 will be explained with reference to FIGS. 1 and 2. It is arranged so as to extend in the longitudinal direction at the center of the machine frame 8, and both ends are rotatably supported via bearings. a rotating shaft 12 and a first rotating shaft 12;
Six pairs of hooks 14, 14... are hung in relation to six fixed shafts 13 arranged and supported at equal intervals across the width direction of the elevator frame 8. It is installed in the same position.

Each of the hooks 14, 14 has a hole into which the fixed shaft 13 can be loosely inserted at the base of the shoulder, which is the upper end, and has a backing plate which can press the shoulder into the cam 15 fixed to the rotating shaft 12 from below. The hook portions serving as the lower end support portions are arranged symmetrically in the axial direction of the rotary shaft 12 so as to face each other between the pair of hooks 14, and the upper end portion is fitted onto the fixed shaft 13. ing.

A pair of springs 17, 17 are wound around each fixed shaft 13, one end of which is fixed to the machine frame 8, and the other end is connected to the shoulder base of the hooks 14, 14, so that the pair of hooks are always connected. The springs 17, 17 have a restoring force that tends to cause the lower end support parts to open in a direction in which they move away from each other.

On the other hand, a rotating shaft 12 having twelve cams 15 fixedly attached to each hook 14, 14 has a gear fitted to one end, and this gear and a motor 16 fixed to the first elevator frame 8 are connected to each other. The motor 16 can be driven in forward and reverse rotation by linking the gears fitted to the output shaft with a chain.

The wrap suspension mechanism 2, 2 configured in this manner is
A pair of hooks 14, 14 are arranged so that the hooks of the lower end support part face each other in the longitudinal direction of the machine frame 8, and each set is arranged horizontally in a row in the same longitudinal direction. When the motor 16 is rotated forward to rotate the rotary shaft 12, each pair of cams 15, 15 rotate simultaneously, and the restoring force of the springs 17, 17 causes the shoulders of the hooks 14, 14 to move against the cams 15, 15. The hooks 14, 14 gradually open the lower end support portions in a direction in which they move away from each other while being brought into sliding contact with the circumferential surface of the hooks 14, 14.

On the other hand, the motor 16 is rotated in the reverse direction and the cams 15,1
5 by a half turn, the shoulders of the hooks 14, 14 move downward against the restoring force of the springs 17, 17.
The lower end support portions gradually close in the direction of approaching each other, and thus it becomes possible to open and close the hooks 14 and 14 simultaneously and synchronously by rotating the motor 16 in forward and reverse directions. With the hook tip part serving as a support part, it is possible to insert the comb rap 6 from both sides in the axial direction and engage both ends of the spool 7 to support it in a suspended state, and also to release the support. .

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

A first rotating shaft 23 and a second rotating shaft 25 that are parallel to each other are rotatably supported on the second lifting machine frame 9 having a rectangular tube shape. It is supported by a plurality of bearing members 24 extending in the longitudinal direction approximately at the center of the inner part, while the second
The 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 20, 20, six in left and right pairs corresponding to the hooks 14, 14, and a nut portion 27 at the upper end thereof is formed on the first rotating shaft 23. In addition to screwing into the male threaded part, the vertical part is loosely inserted into a long hole 28 provided in the bottom plate of the machine frame 9, and is vertically installed. A total of 12 arms 21, 21, 6 in left and right pairs that form a relationship
is rotatably installed vertically around the second rotating shaft 25 by loosely fitting the fulcrum of the intermediate portion.

As shown in detail in FIGS. 5 and 6, the pair of left and right gripping arms 20, 20 have a shape in which the vertical portion and the curved portion are connected to each other, and the upper end of the vertical portion is provided with the aforementioned nut. having a section 27,
One arm 20 is screwed into a right-hand male thread provided on the first rotating shaft 23, and the other arm 20 is similarly screwed into a left-hand male thread so that they are vertically disposed in a symmetrical arrangement.

The first rotating shaft 23 has a gear 29 fitted in an appropriate position in the middle, and this gear 29 is connected to the machine frame 9.
The motor 3 is connected by a chain to a gear 31 fitted to the output shaft of a motor 30 fixed to the
By rotating the first rotating shaft 23 in the forward and reverse directions, the pair of gripping arms 20, 20, each having a nut portion 27 screwed into a right male threaded portion and a left male threaded portion, respectively, approach each other. Or, they move horizontally so that they are separated, and all six of them approach at the same time.
They begin to distance themselves.

Therefore, at the curved lower end portion of each gripping arm 20, 20, a shaft 3 is provided with a roller 18 horizontally protruding from the side of the lower end portion facing the other arm 20.
2, respectively, so as to be rotatable.

As the rollers 18, shoulder rollers with flanges are used in the illustrated example, but rollers without flanges may be used.Furthermore, in the illustrated embodiment, in addition to the rollers 18, an auxiliary roller 33 is installed in parallel with the rollers 33 according to the same installation procedure. It has a structure of a pair of rollers, two on each side on the left and right, and when it cooperates with a drive roller 19 (described later) to sandwich and support the ends of the comb wrap 6 from both the inside and outside, it forms a three-way structure. Although it has the advantage of being able to be supported stably by using a supporting method, it is possible to sufficiently achieve the purpose even if there are only one roller 18 on each side.

On the other hand, a pair of arms 21 and 2 are rotatably supported on the second rotating shaft 25 and arranged symmetrically.
1 is provided with a bearing part having a ball bearing (not shown) fitted in the lower end part of both ends sandwiching the fulcrum, and a protrusion 34 is provided in the upper end part of one arm 21. The driving roller 19 having an integral rotating shaft is rotatably bridged between the bearing parts of the arms 21, 21 and supported horizontally, while the upper end of the arm 21 on which the protrusion 34 is not provided. One end of the spring 36 is locked to the portion.

The other end of the spring 36 is latched to an appropriate position on the upper part of the bracket 26, and the elastic force acts to make each arm 21 stand upright in the vertical direction, and the spring 36 operates at a predetermined tilting position until it reaches the vertical position. The protrusion 34 is brought into contact with a stopper 35 protruding from the bracket 26, so that further swinging is suppressed.

Therefore, as shown in FIG. 4, the drive roller 19 is horizontally installed at a position above the roller 18 and the auxiliary roller 33 in a three-sided manner inside the curved portion of the gripping arm 20. , while the spring 36 always applies elastic force in the direction of approaching the rollers 18, 33, the stopper 35
It is positioned by

A gear 37 is fitted onto the shaft of each drive roller 19 to which elastic force is applied, and this gear 37 is connected to the second rotating shaft via an idle gear 38 rotatably attached to the arm 21. The gear 39 fitted on the second rotating shaft 2
When rotation is applied to 5, six drive rollers 19,
19 are designed to be rotated all at once in the same direction.

Note that 22 is a rotational drive source, such as a deceleration motor, which is fixed to the second elevator frame 9 with its shaft parallel to the second rotating shaft 25, and rotates the gear 40 fitted on the shaft for a second rotation. The drive rollers 19 are connected to a gear 41 fitted to the shaft 25, and the rotation of the motor 22 enables the drive rollers 19 to be actively rotated all at once.

Spool support mechanism 3 having the structure described above
The gripping arms 20, 20 of each pair are connected to the motor 3.
0, the triple telescoping tubes 10 and 1 are separated from each other until they are as far away as possible.
0 is synchronously extended and the second elevator frame 9 is lowered, and the drive roller 19 is positioned below the comb wrap 6', that is, the wrap payout section 11.
As the wrap fleece approaches the final unwinding position, the wrap fleece comes into contact with the upper surface of the wrap 6', of which only a few turns remain, and the arms 21, 21 are moved against the elastic force of the spring 36 to the drive roller. The roller 18 and the auxiliary roller 33 are stopped at a position where the side 19 is restrained from rising, and then the motor 30 is rotated in the forward direction to move the pair of gripping arms 20, 20 toward each other. When the flanges of the rollers 18 that are inserted into the spool 7' of the roller 6' from both sides touch the end of the spool 7', the motor 30 is stopped and the second elevator frame 9 is raised. As a result, as shown in FIGS. 4 and 6, the comb rope 6 can be supported and lifted by the rollers 18, auxiliary rollers 33, and drive rollers 19.

Furthermore, the motor 22 is rotated to rotate the drive roller 19.
By applying rotation to the comb fleece, it is possible to rotate the wrap fleece in a direction to tighten it while supporting the comb wrap 6'.

Next, the air nozzle 4 will be explained.
A structural example is shown in FIGS. 2 and 4, which includes a manifold pipe 42 installed along the second elevator frame 9, and a manifold pipe 42 installed along the machine frame 9 for feeding pressurized air into the pipe 42. An air nozzle 4 is provided in association with a blower device consisting of a blower 43 fixed to the manifold pipe 42 in the longitudinal direction of the manifold pipe 42 in correspondence with the lap hanging mechanisms 2, 2 and the spool support mechanisms 3, 3. In the illustrated example, six slit-shaped air outlets are arranged equally in the diagonally downward outer periphery.
Pressurized air in the form of an air curtain can be blown toward the outer circumferential axis of the comb wrap 6 placed on the comb wrap 1 .

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 extending portion of the wrap former and lowering the first lifting machine frame 8, and rotating the motor 16 semi-reversely, the pair of hooks 14,
After the six fully wound replenishing comb wraps 6 are suspended and supported at once by the wrap hanging mechanisms 2, 2, the machine frame 8 is moved upward (referred to as a wrap support means).

The movable frame 1 is moved by sending a lap splicing signal from the side of the comb group, and the lap feeding portions 11, 11 of the combers are nearing the final feeding when the comb wrap 6' leaves several turns after feeding. The movable frame 1 is guided upward and kept in a standby state.

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

Next, as the comb stops for lap splicing, the second elevator frame 9 is lowered, and the pair of rollers 18, 18 and the auxiliary rollers 33, 3 are lowered.
3 approaches and is pushed up by the contact of the drive roller 19 (see FIG. 10), and then the roller 1
8 and 33 into the spool 7 and the second elevator frame 9 is slightly raised, the comb wrap 6' is wrapped with the spool 7' of the comb wrap 6' supported by three lines, as is clear from the above explanation. It is floated from the feeding section 11 (see FIG. 11).

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

Next, the movable frame 1 is slightly moved in the forward direction, and then the second elevator frame 9 is lowered so that the comb wrap 6' approaches the comb payout rollers 60, 61 as much as possible. In this state, the spool 7' is connected to the wrap feeding portion 11,
11, above the feed-out rollers 60, 61, and on the wrap fleece feed-out side of the spool 7', is located almost perpendicularly to the wrap feed-out line of the feed-out rollers 60, 61, and the shortest distance is maintained between the spool 7' and the feed-out line.

Thereafter, the drive roller 19 is driven in the direction opposite to the direction in which the wrap is fed out, and the wrap fleece is draft cut. (Not shown) Next, the movable frame 1 is moved until the axes of the lap hanging mechanisms 2, 2 are directly above the center of the lap feeding section 11, the first lifting frame 8 is lowered, and the paired hooks 14, 1 are lowered.
By performing the separation action of 4, the lap hanging mechanism 2,
The full lap supported by 2 is placed on the feeding part 11.

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

After that, pressurized air is emitted diagonally downward and backward from the air nozzles 4, 4 in the form of an air curtain, and the pressurized air is sprayed against the end of the wrap of the combed wrap 6 placed on the wrap feed-out parts 11, 11, thereby making the wrap fleece. The unrolling start end is peeled off using pressurized air, and is made to hang downward and is attached to the fleece guide 56 of the wrap unwinding part 11.

In addition, it is preferable to align the posture of the comb wrap 6 on the wrap former side so that the winding end position of the comb wrap 6 can definitely hit the air blown out from the air nozzles 4, 4. In order to set it in the correct position, the second elevator frame 9 can be adjusted up and down from the state shown in FIG.

After confirming that the wrap fleece has fallen down along the fleece guide 56, the wrap feeder 11
When the comb is fed out, the tip of the wrap fleece on the replenishing side and the wrap fleece on the take-out side are fed out in a partially overlapping state.

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

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

In this way, the spool 7 leaving the short fleece remains supported by the spool support mechanisms 3, 3, and the mechanisms 3, 3 are moved horizontally, moved up and down, and released from support to be transferred to a predetermined spool storage section. I can do it.

(Effects of the Invention) The present invention provides spool support mechanisms 3, 3 movable integrally with the lap hanging mechanisms 2, 2 for supporting and transferring the replenishing comb rap 6, and both mechanisms 2, 2..., 3. , 3... can be moved up and down and released from support separately, and air nozzles 4, 4 are provided in connection with the above-mentioned two mechanisms 2, 2, 3, 3 for peeling off and hanging down the ends of the wrapped fleece using air pressure. Starting from the standby position for replenishment and splicing, the lifting and lowering of both mechanisms 2, 2, 3, 3,
By simple sequential operations related to support/release, pitch movement, reverse rotation or braking of the drive roller 19, and jet operation of the air nozzle 4, lap replacement, automatic splicing, and Spool collection can be performed consistently and accurately.

Furthermore, since this device can be used in common for a large number of combers, it can be configured compactly, and by simply adding a spool support mechanism 3 and an air nozzle 4 to a device that was conventionally used only for the purpose of lap transfer, and splicing can be performed automatically and rationally.

In this way, in the combing process, there is no need to separately add a guide mechanism such as a rail, and it is only necessary to add a few mechanisms to the movable frame 1 as it is already installed, so the structure is simple yet multifunctional. It is outstanding as a practical device. Furthermore, by implementing the present invention, the lap mounting stand on the comber group side is omitted, making effective use of space, and on the other hand, the work of lap jointing is eliminated, allowing the driver to perform other advanced management tasks. You can concentrate.
