Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sewing hooking and unwinding operation for a sewing machine for sequentially processing a plurality of cloths wound in a roll shape. , A continuous and mechanical device.

(Prior Art) This type of conventional work is a work other than rewinding and rolling off a cloth (hereinafter referred to as a winding rod) wound in a roll shape,
In other words, from taking out the winding rod, carrying, setting, edge out, cloth alignment, edge alignment, sewing hook, sewing thread cut and sewing thread cut end fraying stop, and tidying and storing the knotted part (mainly by thread knotting). In addition to the fact that almost all the work is labor intensive, most of the work is handheld by the worker during the unwinding and rewinding of the winding rod, which is mechanically performed after the fabric is tied up. It is an efficient task.

As a specific example of the conventional method, a typical anti-union bar method will be described below.

FIG. 1 is a schematic view of this. First, one winding rod 1 to be untied and unwound is taken out of these trolleys 2 for carrying and carrying, and the unwinding rod container 4 of the unwinding rod container 4 is held. Bring it in and rotate it with one hand while pulling out the cloth tip with the other hand. This cloth tip is overlapped with the cloth rear end of the cloth 5 that has already been unwound and most of it has been shaken off, and the ears are aligned. Then, the front and rear cloths are hooked and bound by the manual sewing machine 3. Cut the sewing thread empty ring generated by this sewing thread knotting to an appropriate length with scissors, and perform thread knotting to prevent fraying of the sewing thread empty ring that is continuous with the fabric, and then cut the sewing thread knotting material. The end portion of the cloth that has been pulled out for rearranging is put back into the unwinding stand container (case) 4 while being organized. This completes the work of uncoupling the winding rod carried into the unwinding vessel container 4, and mechanically rewinds the winding rod in the unwinding vessel container 4 by the swing-off device 7 into the spreading-loading trolley 8. Shaken off. As the unwinding of the unwinding rod of this winding rod progresses and the trailing edge of the cloth passes the detector 6, the swinging-off device 7 stops at the same time, and immediately thereafter, this swinging-off device 7 reverses for a predetermined short time and then The rear end of the cloth for tying up the winding rod is unrolled, and all the unwinding work is completed by manually taking out and storing the empty winding core. And the union and unwinding will be performed alternately.

(Problems to be Solved by the Invention) As described above, most of the conventional unwinding and unwinding work of the round rod cloth is performed manually. It is a burden.

2 The work involved in hanging and tying the sewing machine is extremely complicated and the work efficiency is extremely low.

3 The operating rate of the workers during the mechanical rewinding and swinging off of the winding rod is very poor.

4 Most of the work of uncoupling and unwinding is manual work, so it lacks stability for a long time, and it is difficult to connect it to the next process.

There are many problems such as.

The stacking device 400 is usually composed of the cloth swinging-off device 27 and the spread loading carriage 26.

On the other hand, the winding rod supply device 200 in the continuous automatic unwinding and unwinding rod machine 100 according to the present invention is, for example, as shown in FIG.
It is composed of a loading carriage 201 having a built-in multi-tiered sloping base 3 and a conveying device 201 having a single conveyer conveyor 4 capable of moving up and down.

Hereinafter, a specific configuration of the winding rod supply device 200 of the continuous automatic unwinding rod machine 100 according to the present invention will be described.

That is, when a plurality of fabric winding rods 1 to be unwound and unwound are rolled down on the right descending inclined table 3 that divides the inside of the loading carriage 2 in multiple stages, the outer winding ends wind around the outside of the winding rod. The cart 2 loaded in such a direction is arranged in parallel with the machine as shown at the left end of FIG.

A conveyor 4 for moving a winding rod upright to the cart 2
Will stop rotating as soon as it detects that the uppermost winding rod of the tilt table 3 in the carriage 2 has been completely conveyed by the idle rotation of the conveyor 4, and will rotate the four ball screw shafts 5 capable of forward and reverse rotation. Therefore, it starts descending and stops at the detector A ₂ provided at a predetermined position to convey the second winding rod of the tilt table 3, and then the conveyor 4
The lift 7 attached to the lift chain 6 provided in parallel with the following also descends following this and stops at the detector B ₂ provided corresponding to the stop position of the conveyor 4 and waits.

Incidentally, the lift chain 6 in the present invention may be provided so as to be connected to the above-mentioned transfer device 201, or the winding rod unwinding device 3 arranged continuously to the transfer device 201.
It may be provided by being connected to 00, or may be independently arranged between the transport device 201 and the winding rod unwinding device 300. The winding rod unwinding device 30 for the winding rod 1 discharged from 201 at an appropriate timing
Any material can be supplied as long as it can be supplied to the introduction portion of 0.

Next, a pressing tool (not shown) provided at the left end of the conveyor 4
Is actuated and the second stage of the load receiving plates 8 provided at the right end of each stage of the tilting platform 3 in the carriage 2 is released by releasing its clasp (not shown). As shown in the figure, it forms a straight line with the second-stage tilt table 3, and the plurality of winding rods 1 loaded on the second-stage tilt table 3 all roll in order and start to rotate at the same time. These winding rods are stacked one by one on the conveyor 4 from the second-stage load receiving plate 8 by the plurality of slip stopper claws 9 attached to the conveyor 4.

When the heads of these winding rods on the conveyor 4 reach the detector 10, the leading winding rods drop from the right end of the conveyor 4 onto the lift 7 waiting below, and at the same time the rotating conveyor 4 stops. . The stopped conveyor 4 waits until the lift 7 becomes empty and returns to the position of the detector B ₂ .

On the other hand, the lift 7 loaded with the leading winding rod rises as the lift chain 6 starts to rotate, and stops rising by the detector 11 provided at the upper limit predetermined position of the lift chain 6, and the lift chain 6 moves. The air cylinder 12 provided so as to suspend the lift 7 is extended to lift the lift 7.
Is tilted forward, and the winding rod loaded on this rolls down onto the slide 13 provided in parallel with the lift chain 6 as shown in the figure.

The lift 7 that has finished dropping and supplying the winding rod immediately returns to a horizontal position due to the shortening of the air cylinder 12, and at the same time, starts to descend due to the rotation of the lift chain 6, and is detected at a predetermined stop position. The conveyor 4 which has been stopped at the container B ₂ starts rotating again, so that the remaining winding rod on the second-stage load receiving plate 8 of the carriage 2 is conveyed by the slip-stop claw 9 to convey only one conveyor. 4 is loaded on the conveyor 4, and when the leading winding rod on the conveyor 4 reaches the detector 10, the leading winding rod falls from the right end of the conveyor 4 onto the lift 7 stopped below, and at the same time the conveyor 4 is rotating. Stops.
In this stopped conveyor 4, the lift 7 becomes empty and the detector
It will wait again until it returns to the position of B ₂ .
The lift 7 on which the leading winding rod is loaded again rises when the lift chain 6 thereof starts to rotate, and the lift 7 is stopped by a detector 11 provided at a predetermined upper limit position of the lift chain 6 to lift the lift 7. Stand by with one winding rod loaded on top.

Here, the conveyor 4 and the lift 7 repeat such an operation several times so that the conveyor 4 or the carriage 2
In the case where all the winding rods on the second sloping table 3 in the above are carried out by the lift 7, even if the empty lift 7 is stopped at the position of the detector B ₂ , the conveyor 4 moves above the lift 7. Since the winding rod does not fall and the detector 10 does not detect it, the conveyor 4 continues to idle and stops rotating after a certain time, and starts to descend due to the rotation of the four ball screw shafts 5 that can be rotated in the forward and reverse directions, and then tilts. The detector A ₃ provided at a predetermined position to convey the third winding rod of the table 3 stops, and the lift 7 also descends following this, and the detection is provided corresponding to the stop position of the conveyor 4. By stopping at the container B ₃ , all the winding rods on the third-stage inclining table 3 are also conveyed in order in the same manner as the winding rod on the second-stage inclining table 3 in the carriage 2 described above. By repeating such an operation thereafter, the winding rods loaded on all the tilt bases 3 in the carriage 2 are sequentially carried. It is is will be.

Next, a specific example of the configuration of the winding bar unwinding device 300 used in the continuous automatic unwinding and unwinding machine 100 according to the present invention will be described in detail. That is, the winding rod unwinding device according to the present invention

A sewing machine hooking and uncoupling means 306 including a sewing machine 39 and a sewing machine thread empty ring suction means 46 for sucking an empty ring of extra sewing thread that has not been sewn to the cloth on at least one of the ends of the cloth. It is composed of

Hereinafter, a specific configuration of the winding rod unwinding device 300 according to the present invention will be individually described.

By the way, the winding rod that has fallen from the lift 7 onto the slide 13 rolls on the slide 13 and
A side plate 14 extending the right end of 13 vertically, a side plate 15 provided on the opposite side of the side plate 14, a main reversing roll 16 capable of forward and reverse rotation provided below the middle of the side plates 14 and 15, a lower end of the side plate 14 and a main plate. Auxiliary roll 17 and side plate provided very close to the unrolling roll 16
Auxiliary roll 18, which is very close to the lower end of 15 and is installed with a space between it and the main unwinding roll 16, and two winding rod guides provided between the side plates 14 and 15 that can move back and forth. Board
It rolls down into the upper unwinding bar base 302 formed by being surrounded by 19 and is held by the main unwinding bar roll 16 and the auxiliary roll 17 or 18, and FIG. I saw it.

Next, the winding rod dropped and supplied onto the upper unwinding rod base 302 is positioned in the width direction. When the detector 20 (not shown in FIG. 3) of FIG. 2 detects that the winding rod falls into the upper unwinding rod base 302, the two winding rod guide plates 19 of FIG. From each end position, they started to approach each other at the same speed along the guide bar 21 (driving part is not shown), and were cut out so that the paper tube protrusions 22 at both ends of the winding rod could pass sufficiently. When one of the two winding rod guide plates 19 hits the end face of the winding rod, it starts pushing the winding rod, and the winding rod on the upper unwinding bar base 302 starts to move toward the other winding rod guide plate 19. become,
When the other winding rod guide plate 19 hits the other end face of this winding rod, the detectors 23 provided on the two winding rod guide plates 19 together detect that the winding rod guide plates 19 are approaching each other. The two winding rod guide plates 19 temporarily stop and then retract slightly and stop. Through the above operation, the winding rod dropped and supplied onto the upper unwinding rod base 302 is positioned in the width direction. That is, the centering operation has been performed, and this state is shown in FIG.

Then, the main unwinding roll 16 rotates counterclockwise 2-3 times, and the winding rod on the main unwinding roll 16 is rotated 2-3 times in the winding direction.
Rotate the roll end of the winding rod to make it wrinkle-flat, and then the main unrolling roll 16 starts to rotate clockwise to start the outer end of the winding rod, and the main unrolling roll 16 and the auxiliary roll 18 The end of the winding rod begins to come out from the gap and all slides down on the stand 24.

Then, it starts to descend vertically from the lower right end of the slide 24, and when the terminal reaches the detector 25 provided at the lower right end of the slide 24, the main unrolling roll 16 temporarily stops its rotation and then slightly reverses. Wind up the terminal a little and stop. With the above operation, the end of the winding rod on the upper unwinding bar base 302 has been made, and this state is shown in FIG.

On the other hand, the tip is already ahead of this winding rod (reverse winding of the winding rod).
The cloth that has been unwound and finished the unwinding is supplied to a cloth collecting apparatus 400 that is mostly composed of the cloth swinging-off device 27, the spread-loading trolley 26, and the like. Alternatively, as another example of the fabric collecting device 400 according to the present invention,
It may be supplied directly to an appropriate winding machine or may be sent to a continuous supply device to the next processing equipment by a device for shaking off the cloth, and the cloth residue is from the cloth pulling roll group. It has been hung down and is waiting to stop just above the horizontal position of the detector.

Main roll roll 16 that will be unrolled from now on
This means that the outer winding end portion of the upper winding rod and the inner winding end portion of the winding rod that has already been unwound face each other. These are shown in FIG.

Next, the edges of the two cloth fabrics, which are vertically suspended from the winding rod cloth side and the unwinding cloth side, are aligned. The two sides of each of the two fabrics, that is, the fabric side of the first side portion, for example, the right side portion and the second side portion, for example, the left side portion, are sandwiched in the center of the fabric. All of the four ear grippers 29, which are provided so as to be movable in parallel and horizontally, start moving at the same speed toward the cloth ear at the same time, and this one gripper 29
When it hits the fabric ear, two air nozzles 31, which are horizontally installed toward the inside of the tip of the fabric ear guide plate 30 of the holding device 29, spray at the same time when the holding device 29 is started. The high-speed air, which had begun, is also blown from both sides of the fabric ear portion, and the fabric ear portion enters the inside of the holding device 29 while the folding wrinkles are sufficiently extended. This is shown in FIG. When the cloth ear reaches the cloth edge detector 32 provided at the lower end of the ear gripper 29 in this way, the ear gripper 33 also provided on the side surface of the ear gripper 29 is activated. Then, the cloth ears are gripped, and at the same time when the other three gripping tools 33 have finished gripping the respective cloth ears, the gripper 29 stops moving and approaches, and the air nozzle 31 also operates at high speed. Stop injection.
This is shown in FIG.

In the embodiment of the present invention, as shown in FIGS. 7 to 9, the two ear holding portions 29B and 29D on the right side which is the first side are fixedly integrated. To form a first pair of first ear pinching portions, while a second pair
The two ear holding portions 29A and 29C on the left side, which is the side of the, are connected so as to be integrated with the fixing portion to form a second pair of ear holding portions that is a second pair, and The respective ear sandwiching portions forming the first pair and the second pair are configured to be able to move in the approaching direction and the separating direction in synchronization with each other.

Furthermore, the two ear gripping portions 29B and 2 that compose each pair.
The distance from 9D and the distance between the two ear gripping parts 29A and 29C are
It can be adjusted appropriately.

By executing the function of the ear gripping section, the two edges of the cloth are aligned.

Next, preparation is made for stitching the cloth ends with these two edges aligned. First, in order to eliminate the slack and creases in the width direction of the fabric caused by the holding device 29 holding the respective fabric ears and approaching each other, this time,
When each of the grippers 29 starts to retreat at the same speed while gripping each of the cloth ears, slack and creases are eliminated, and the tension of the gripping cloth begins to act on the gripper 29. When all the spring-loaded limit switches 34 provided in the drive devices of the four holding devices 29 are activated, the four holding devices 29 stop retreating at the same time. This is the ninth
Shown in the figure.

Next, as a preparation for stitching, the two cloth cloths are woven together. After the main unwinding roll 16 rotates slightly clockwise, the winding rod on the main unwinding roll 16 is slightly unwound and loosens between the winding rod side holding device 29 and the winding rod side. two clamping devices 29 ^a and 29 ^B are clamped vessel 29 ^C for I connexion solutions rod fabric side to the operation of the pusher 35 while sandwiching the fabric ears each
And 29 ^D , and at the same time, the fabric press bar 36 provided under the holding device 29 is pressed by the pressing tool 37.
Of the two cloths that are moved vertically by the operation of the holding device 29 and are vertically held by the holding device 29.
Press down on 38 to secure. This is shown in FIG.

With the above, the preparation for suturing the two cloth cloth ends is completed, and finally, the sewing machine is knotted and knitted. Next, the running sewing machine 39 in the winding rod unwinding device 300 according to the present invention, and a sewing thread that sucks an empty ring of the extra sewing thread that has not been sewn to the cloth on at least one of the end portions of the cloth. A specific example of the sewing machine hook-and-tie means 306 including the air-ring suction means 46 will be described. First of all
In FIG. 1, a known automatic traveling sewing machine 39 in which the sewing machine head is tilted by 90 ° and attached, starts self-propelled from a predetermined position on the right end of a sewing machine traveling rail 40 provided in the width direction of the fabric, and is provided in front of the sewing machine stitching portion. When the cloth edge is introduced into the two cloth edge guide plates 41, the cloth edge detector 42 shown in FIG. The high-speed air nozzle 43 for straightening wrinkles and the high-speed air nozzle 44 for blowing out the mess-cut cloth of the cloth anti-smear cloth start to spray, and at the same time, the running sewing machine 39 makes a slight empty stitch, and then mess-cuts the sewn cloth end straightly. Start stitching the fabric. At this time, the tips of the ears of the cloth are introduced into the sewing portion of the running sewing machine 39 while the wrinkles are sufficiently extended by the high-speed air jetted from the high-speed air nozzle 43, and the mess-cut cut cloth is the high-speed cutting cloth. The high-speed air jetted from the air nozzle 44 blows off the knife portion and hangs down from the end cut cloth portion. Then, when the cloth edge detector 45 behind the sewing section of the sewing machine reaches the cloth edge that is sewn by messing the cloth end, the cloth edge breaks, the wrinkles are stretched, the high-speed air nozzle 43 stops jetting, and the running sewing machine 39 The speed is reduced while synchronizing the running and the suturing, and the fabric edge is stopped so as to be directly above the sewing thread empty ring suction device 46 provided behind the sewing portion of the sewing machine in FIG. Next, this sewing thread empty ring suction device
46 moves up and sucks down the excess empty sewing machine thread loop that hangs from the right ear end stitching portion of the cloth, that is, the stitching start point, and descends. Then, the sewing machine thread melting cut heater 47, which is provided between the cloth stitching section and the suction device 46 and is heated to a temperature higher than the melting cutting temperature of the sewing machine thread and is on standby, advances to melt the excess sewing thread empty ring. And then retreat. As a result, the cutting ends of the sewing machine empty loop that is continuous with the stitching start point of the cloth are prevented from fraying due to the fusion of the sewing machine threads, and the cut excess sewing machine empty circle is sucked by the suction device 46. Are eliminated by. Next, the traveling sewing machine 39 again starts traveling and stitching at the same time, and continues stitching while messing the fabric cloth. During this time, the four ear grippers 33 release their respective ear grips, and all the ear grippers 29 expand and retract, returning to their original positions and aligning the next cloth winding rod. Wait until.

Then, the fabric edge detector 45 attached to the traveling sewing machine of FIG. 11 progresses the stitching, and the fabric mesquished immediately before passing through the left edge of the fabric is completely separated from the fabric cloth and falls, Immediately after passing, the high-speed air nozzle 44 blows off the messcut cloth of the cloth and the jetting stops, and the running sewing machine 39
Stops only the stitching to reduce the running speed, and stops so that the left edge of the cloth is right above the sewing machine empty-ring suction device 46 in FIG. Next, the sewing machine empty-ring suction device 46 ascends and sucks and lowers the excess sewing thread empty-loop that is connected to the stitching portion of the running sewing machine 39 from the left ear end stitching portion of the cloth, that is, the stitching end portion. This is shown in FIG. Then, the sewing machine thread melting cut heater 47 advances again, and the excess sewing machine thread empty ring is melted and cut back. As a result, the cut ends of the empty loop of the sewing thread, which is continuous with the stitching end portion of the cloth, are prevented from fraying due to the fusion of the sewing threads with each other. The sewn part of the sewn part will hang down inside the aspirator 46. By the above-mentioned operation, the sewing of the two cloth cloth ends with the sewing machine is completed.

Next, the unwinding of the winding rod on the upper unwinding rod base connected to this connection portion is performed, and first, the press bar 36 that press-fixes the fabric connection portion in FIG. 10 presses this. It is returned to the origin by the operation of the tool 37, and the connection part is made free. Subsequently, the cloth pulling roll group 28 and the swing-off device 27 shown in FIG. 2 start to operate slowly, and the cloth is unraveled and loaded.
The umbilical part hung on the sewing machine starts to be loaded and unloaded to 26. When the cloth comes into contact with the centering roll 48 of the cloth, this starts centering of the unwound cloth, and the main unrolling roll 16 starts rotating clockwise to unwind the winding rod supported on it. The bar is started, and soon after the cloth is unwound, the cloth is centered and shaken off at a predetermined cloth speed. During this time, the traveling sewing machine 39 retracts the sewing machine traveling rail 40 and returns to the origin, and waits until the next winding rod is sewn by the sewing machine. In this way, after the winding rod is unrolled for a while, the main unwinding roll 16 moves horizontally to the swing-off side while rotating, and the winding rod 1 in the unwinding rod constitutes the bottom portion of the lower unwinding rod stand 303. It is dropped onto the roller group 49 and immediately returns to its original position. At this time, the two winding rod guide plates 19 shown in FIG. 5 start to expand along the guide bar 21, return to their original positions, and stand by until the centering of the next winding rod. .

In this way, when the unwinding of the winding rod on the roller group 49 forming the bottom portion of the lower unwinding rod stand 303 progresses to form only the paper tube, the paper tube rolls the roller forming the bottom portion of the lower unwinding rod table 303. Group 49
From the roll gap, it falls onto the paper tube conveyer 50 provided below the lower unwinding bar stand 303 and is discharged at a proper time. On the other hand, the final end of the unwound fabric, that is, the inner winding end of the winding rod passes through the detector 51, and at the same time, the main unrolling roll 16 and the centering roll 48 stop their rotation, and the pulling roll group 28 and The swing-off device 27 reduces its speed, and the end-rolled end wrinkle straightening bar 52 causes the pressing tool 53 to
When the inner winding end passes through this gap, the wrinkles are extended by the movement of the inner winding end and the fixed inner winding end wrinkle extending bar 54 forming a narrow gap. Then, at the same time when the inner winding end passes through the detector 55 of the inner winding end, the pull-up roll group 28 and the swing-off device 27 are stopped, and the inner winding end remains slightly above the detector 55. As described above, the unwinding of the winding rod dropped and supplied onto the lower unwinding rod stand 303 is completed.

Subsequently, the end of the unwinding rod of the unwinding rod of the next winding rod is to be exposed, and the pull-up roll group 28 and the swing-off device 27 start to reverse at a low speed and are suspended by these. The inner winding end of the unraveling cloth that stayed slightly above the detector 55 slowly descended along the vertical guide plate 56,
After temporarily stopping at the horizontal position of the detector 25 provided below, the pulling-up roll group 28 and the swing-off device 27 are rotated slightly forward and stopped, so that the inner winding end of the unraveling cloth is Stop and wait just above the horizontal position of the detector 25.

On the other hand, during this time, the winding rod to be unwound next is dropped and supplied from the lift 7 waiting at the upper limit predetermined position to the upper unwinding rod stand that has already finished the unwinding and is waiting, The supply unwinding bar cycle has started.

By performing a series of the above-described series of winding rod supply / congealing and unwinding rod cycles in succession, all of the plurality of fabric winding rods 1 loaded on the loading carriage 2 are mechanically sequentially supplied / conveying and unwinding. Will be sticking.

(Effects of the Invention) By mechanically complicating the work of unwinding and unwinding the conventional round wound cloth, which is often complicated and inefficient, (1) From the removal of the unwinding rod to the unwinding and unwinding work No longer needed, and the unmanned work of unionizing and unraveling was achieved. (Conventionally, one person was used for each unwinding rod machine.) (2) The unwinding rod work was speeded up, and the productivity of this was greatly improved.

(3) The stability of the unwinding rod work over a long period of time was dramatically improved, and it became possible to connect it to the next process.

(4) The quality of the mating part was improved stably. In particular, when the sewing machine thread is made of polyester, T / C, nylon, etc., the cut portion of the sewing machine thread is melted by melting the empty ring of the extra sewing machine thread with a heater. The sewing threads fused to each other, which provided an anti-fraying effect, eliminating the need for an anti-fraying thread knot.
