Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a foil stamping machine that stamps scales at predetermined intervals on the edges of a long piece of cloth.

(Conventional technology) For example, long pieces of cloth such as clothing are 120 m or 240 m long.
It is cut into predetermined unit lengths such as 10m and 15m before being shipped.

Long pieces of cloth are cut to lengths a little longer than the predetermined length using a measurer, but it takes time and effort to apply the measurer to the measurement, resulting in poor work efficiency.

In order to perform the above-mentioned work efficiently, the applicant attempted to apply a scale to the selvage of the cloth as a substitute for a measure, and as a means of doing so, the applicant applied an existing foil stamping machine that stamps trademarks and quality indications on the selvage of long cloth. I paid attention.

This foil stamping machine, as shown in Figures 7 and 8,
A foil stamping device 30 provided on the running path of the cloth 9;
A pair of guide rollers 34, 34, 35, 35 are provided on each side of the foil stamping device, and lifting rollers 36, 36 are provided so as to be able to rise and fall between each guide roller 34, 34, 35, 35 and move up and down alternately. , a drawing roller 25, 2 that draws the cloth at a constant speed.
It consists of 6.

When the elevating roller 36 on the downstream side of the foil stamping device 30 descends while catching the cloth, the retracting roller 2
Even though the rollers 5 and 26 are rotating at a constant speed, the amount of cloth pulled in by the rollers 25 and 26 and the amount of slack in the cloth due to the lowering of the lifting roller 36 correspond to each other, so that the amount of slack in the cloth is instantaneously below the foil stamping device 30. The running of the cloth is stopped, and during this time the marking drum 5 of the foil stamping device 30 is lowered, and the foil-covered tape T passed between the drum 5 and the cloth is pressed against the cloth to stamp the cloth with foil.

(Problems with the prior art) As mentioned above, during foil stamping, the cloth is momentarily stopped by the correspondence between the amount of slack in the cloth due to the lowering of the lifting roller 36 and the amount of cloth being pulled in by the pulling rollers 25 and 26. Even if the timing of raising and lowering the raising and lowering roller 36 is constant, the guide rollers 35, 34
The feed rate of the cloth was not constant due to fabric slips, etc. Therefore, even if the scales were stamped with foil, the length between the scales varied, making the scales completely unreliable and unusable as a measurer.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned problems, and is installed on the running path of the cloth and sends out a signal every time the cloth passes a certain length in accordance with the stamping interval for the scale. A length measuring device 8 that generates a signal, a cloth feeding device 2 that performs an intermittent running drive that repeatedly moves and stops the cloth, and a cloth feeding device 2 that is movable up and down on the cloth traveling path and descends in synchronization with the stop of the intermittent feeding of the cloth by the cloth feeding device. a support stand 4 that is rotatably supported on the support stand 4 and has a scale convex portion 53 formed on its outer periphery; A foil-covered tape T that passes between a driving device 52 that rotates and drives the ticking, and the cloth running path and the marking drum 5.
The cloth feeding device 2 is configured with a driving device 71 that drives
8, the cloth feed is stopped intermittently by a signal from the length measuring device 8 every time the cloth moves a certain length, and the timer 3 stops every time the foil stamping is completed a predetermined number of times.
8 is activated, and the cloth feeding device 2 is activated for the set time to feed the cloth by the length of the cutting margin. When the cloth feeding is completed by the length of the cutting margin, the cloth feeding device 2 is operated again according to the signal from the length measuring device 8. It is characterized in that the cloth feeding device 2 operates.

(Operation and Effect) When the length measuring device 8 detects that the cloth has traveled a predetermined hot stamping interval distance, the cloth feeding device stops and the cloth stands still. In synchronization with this, the marking drum 5 descends, and the foil-covered tape T passed under the drum 5 is pressed against the cloth by the scale convex portion 53 protruding from the outer periphery of the drum. Foil stamp.

The cloth feeding device 2 stops feeding the cloth in response to a signal that the length measuring device 8 detects that the cloth has traveled an accurate predetermined distance. It is possible to cut a long piece of cloth into a predetermined length based on the standard, and there is no need to apply a measurer as in the past, greatly improving work efficiency.

After repeating the above operations and completing a predetermined number of foil stampings, the timer 38 activates the cloth feeding device 2 for a short time to feed the cloth by the length of the cutting margin, and the foil stamping operation is performed again.

As described above, since a cutting allowance can be secured for each unit length of the cloth, the cloth will not be cut shorter than the required length.

(Example) FIG. 1 shows a state in which a cloth 9 is stretched around a foil stamping machine.

The above foil stamping machine can stamp numbers every 1m,
Also, a predetermined cutting allowance can be provided for each arbitrary length in the range of 1 to 15 cm, and foil stamping can be performed again every 1 m.

In the example, the length is 240m with seams in multiple places.
Numbers 13 to 0 are foil-stamped in descending order every 1m on the long cloth 9, a cutting allowance of 10cm is provided every 13m, and the process of foil-stamping numbers every 1m is repeated.

However, if the fabric seam passes the hot stamping position during foil stamping from 13 to 0, the fabric will stop running immediately, and no matter what the number immediately downstream of the fabric seam is, it will continue to flow immediately upstream of the fabric seam. The number 13 is foil stamped, and then the numbers up to 0 are foil stamped in descending order in the same way as above.

The foil stamping machine has vertical columns 11 erected at the four corners of the base 1,
A support frame 12 is fixed on the pillar.

A guide roller 1 is installed on the support frame 12 and the vertical column 11.
3 is rotatably supported, and the long cloth 9 folded upstream of the base 1 is pulled up to one end of the support frame 12, descends along the vertical column 11, passes over the base 1, and then It rises along the other vertical column 11 and further hangs down from the other end of the support frame 12 via the swinging housing 15.

The cloth feeding device 2 that feeds the cloth 9 from the upstream side to the downstream side includes a pair of large and small pull-in rollers 25 and 26 arranged approximately in the center of the base 1 and a pair of feed-out rollers 27 and 27 arranged at the downstream end of the support frame 12. and a motor 21 that drives these rollers 25 and 27.

The motor 21 rotates an intermediate shaft 23 via a reducer 22 and a chain transmission means, and the intermediate shaft 23 is connected to a clutch 24 and chain transmission means 24a, 24b.
It is connected to the pull-in roller 25 and the feed-out roller 27 via.

Although the intermediate shaft 23 is constantly rotating, the clutch 24 is disengaged by a signal from a length measuring device 8, which will be described later, and the intermediate shaft 23 and the chain transmission means 24a, 24b are separated, and the feeding of the cloth 9 is stopped.

A brake (not shown) is connected to the retracting roller 25 and acts at the same time as the clutch 24 is disengaged, so that the retracting roller 25 is stopped instantly.

The swinging housing 15 is connected to the support frame 12 by a wire 16.
Each time the cloth 9 passes through the housing 15 for a certain length, the cloth 9 swings back and forth by the swinging device 10 driven by the chain transmission means 24b. The cloth 9 is folded into a bundle.

As shown in FIG. 4, a length measuring device 8 for measuring the feed amount of the cloth 9 is provided on a horizontal plate 17 fixed between the vertical columns 11, 11 on the upstream side.

The length measuring device 8 has a shaft 82 rotatably supported on a mounting plate 81 perpendicular to the direction of movement of the cloth, and a rubber roller 83 that contacts the cloth and rotates by friction as the cloth runs. , 83 are fixed.

A circular rotation detection plate 85 with slits 84 formed at equal intervals on the outer periphery is attached to the shaft 82, and a detector 86 provided on the mounting plate 81 is inserted into the slits 8.
After counting 4, the detection plate 85 and the rubber roller 83
The number of rotations of the cloth 9, and therefore the amount of travel of the cloth 9, is detected.

In the embodiment, the outer circumferential length of the rubber roller 83 is 30 cm.
There are 30 slits 84 on the rotation detection plate 85, and each time one slit 84 is counted, the cloth is fed 1 cm.

A micro brake 87 prevents overrun rotation of the rubber roller 83 when the cloth stops running on the shaft 82 to which the rubber roller 83 is attached, and a known seam detector 88 detects the seam of the cloth based on changes in the thickness of the cloth. is in place.

The rotation detector 86 is connected to the control panel 18
The rotation detector 85 detects the slit 84.
Every 100 counts, that is, every time the cloth travels 1 meter, a signal is issued to operate the lifting device 44 of the marking drum 5 of the foil stamping device 3, which will be described later.

The control panel 18 is provided with a setting button 19 for setting the cutting length of the cloth, and a first timer 38 and a second timer 39 for operating the feeding device 2 for a predetermined time. If the rotation detector 86 emits the number of signals set by the button 19, that is, the fabric 9 has reached the predetermined cutting length, 13 m in the example.
When the fabric is moved for 10 cm, the feeding device 2 operates for the time set in the first timer 38 and feeds the fabric by 10 cm.

Further, when the cloth seam detector 88 issues a detection signal, the feeding device 2 operates for the time set in the second timer 39, and feeds the cloth 9 by about 30 cm.

The length measuring device 8 and the cloth pull-out rollers 25, 26
A foil stamping device 3 is installed on the base 1 between the
The foil stamping device 3 stamps a cloth 9 on a base 1 as shown in FIG.

The support stand 4 has a pair of arms 41, 4 whose base ends are pivoted to each wall plate 31, 31 so as to be rotatable in a vertical plane.
1 and the arms 41, a connecting plate 42 that connects the arms 41, 41;
43, and a lifting device 44 is connected to the support base 4.

The lifting device 44 has a rotating shaft 45 penetrating through the wall plates 31, 31, and pins 4 at eccentric positions at both ends of the shaft.
A disc 46 having a protruding pin 47 is attached thereto, and the pin 47 and the arms 41, 41 of the support base 4 are pivotally connected by a rod 48.

The rotation shaft 45 is connected to the intermediate shaft 23 of the cloth feeding device 2 via the gear transmission means 4a, the one-turn clutch 40, and the chain transmission means 24c, and is connected to the one-turn clutch 40 by the signal from the length measuring device 8. A linked solenoid (not shown) operates to actuate the one-turn clutch 40, causing the rotating shaft 45 to make one rotation,
The pin 47 and rod 4 at eccentric positions on the rotating shaft 45
The support stand 4 connected at 8 is swung up and down once around the arm 41.

Support arms 50, 50 are protruded from the lower surface of the connecting plate 43 on the free end side of the support base 4, and a rotating shaft 51 is supported in parallel with the plate 43 by passing through the arms 50, 50.

A stamping drum 5, a first slit plate 6 for regulating the rotation angle of the drum 5, and a second slit plate 60 for determining the stamping start position of the drum 5 are attached to the rotary shaft 51.

The marking drum 5 has scale protrusions 53 protruding from its outer periphery at equal intervals. As shown in FIG. 5, the scale convex portion 53 of the embodiment divides the outer periphery of the drum 5 into 16 equal parts and sequentially represents numbers 0 to 15 in the rotational direction of the drum 5. The marking drum 5 is approximately 20 cm further than the cloth seam detector 88.
It is located on the downstream side.

Sixteen slits 61 are formed at equal angles in the first slit plate 6, and numbers 0 to 15 are marked on each slit in order in the direction of rotation of the first slit plate 6.

The first slit plate 6 aligns each slit 61 with the scale convex part 53 of the marking drum 5 in phase, and the first slit plate 6 corresponds to the number of the scale convex part 53 of the drum 5.
For example, the numbers on the stamping drum 5 are shifted by 180°.
When the number 13 on the first slit plate 6 is located directly below, the number 13 on the first slit plate 6 is located directly above.

A slit 62 is formed at one location on the outer periphery of the second slit plate 60, and the second slit plate 60 is attached to the first slit plate 6 so as to be positionable in the rotational direction.

On the support stand 4 are the first slit plate 6 and the second slit plate 6.
a first detecting the slit 62 of the slit plate 60;
Second detectors 63 and 64 are provided, and the first detector 6
3 is a slit 61 located directly above the first slit plate 6
The second detector 64 is placed at a position where it detects that the slit 62 of the second slit plate 60 is positioned directly above.

A rotary drive device 52 is disposed on the connecting plate 42 on the base end side of the support base 4, and the drive device 52 and the rotary shaft 51 of the marking drum 5 are linked through a chain 54.

The rotary drive device 52 of the embodiment is a so-called synchro motor 52a that rotates at a very low speed in exact proportion to the number of cycles of the AC power supply.

The synchro motor 52a rotates in response to a detection signal from the limit switch 37 that detects the raised position of the lifting device 44, and rotates the slit 6 of the first slit plate 6.
Stops every time 1 is detected. However, if the cloth travels by the numerical value set by the cloth length setting button 19, which is 13 meters in the embodiment, the second slit plate 60
The synchro motor 52a rotates until the second detector 64 detects that the slit 62 has reached directly above, and the number 13 on the marking drum 5 faces directly below. or,
When the cloth seam detection device 88 issues a signal indicating that a cloth seam has been detected, the synchro motor 52a
Similarly to the above, the second slit plate 60 rotates while the slit 62 is positioned directly above.

A tape supply reel in which two reel support shafts 75 and 76 are rotatably attached to the upper part between the wall plates 31 and 31 of the foil stamping device 3, and a foil-covered tape T is wound around the reel support shaft 76 on the side of the cloth transition path. 77 is the tape take-up reel 7 attached to the other reel support shaft 75.
8 is installed.

Foil-covered tape T is a strip of paper with gold foil applied to one side.

The foil-coated tape T pulled out from the supply reel 77 is passed around tape guide shafts 79, 79, 79 that are freely rotatably disposed on both sides of the lower part of the stamping drum 5, and then passed through the lower part of the stamping drum 5 and taken to the take-up reel. Guided by 78. A pair of tape tensioning rollers 70, 70 are rotatably disposed at positions remote from the marking drum 5 with respect to the cloth transfer path, and a rotation drive device 71 is linked to one tensioning roller 70. The rotary drive device 71 drives the marking drum 5.
The synchro motor 71a is similar to the drive device 52 in the above, and rotates once every time the limit switch 37 detects the raised position of the support base 4, and rotates the tension roller 70 by an angle corresponding to one pitch of the tape T. let

The roller 70 and the take-up reel shaft 75 are connected via a belt 73 and a slip mechanism 74,
The take-up reel shaft 75 is rotated by the rotation of the roller 70.
rotates and winds up the tape T onto the reel 78.

If a large tension is applied to the tape between the roller 70 and the take-up reel 78, the slip mechanism 74 will work and the rotation will not be transmitted to the take-up reel shaft 75, so that the tape T can be cut without straining the tape. This will be prevented.

However, the numbers 13 to 0 were stamped on the cloth in descending order every 1 m, and a cutting allowance of 10 cm was set between 0 and 13.
I will explain the procedure for foil stamping the numbers 13 to 0.

As shown in FIG. 1, the long cloth 9 is passed through the cloth foil stamping machine, and as shown in FIG. match.

Set the cutting length setting button 19 on the control panel 18 to the value 13. When the start button (not shown) is pressed, the synchro motor 52a rotates while the slit 62 of the second slit plate 60 reaches the directly above position, and a second detector detects when the slit 62 of the second slit plate 60 reaches the directly above position. 64 is detected, the synchro motor 52a stops, and the number 12 on the marking drum 5 faces straight down.

In this state, the electric circuit of the control panel 18 is turned on, the feeding device 2 is activated, and feeding of the cloth 9 is started. Every time the cloth is fed by 1 meter, the length measuring device 8 operates the one-turn clutch 40 of the lifting device 44 that raises and lowers the support stand 4, thereby causing the support stand 4 to reciprocate up and down once. As a result, the stamping drum 5 presses the foil-covered tape T against the edge of the cloth by means of the downwardly facing scale convex portion 53 representing the number 13, thereby stamping the foil.

When the support base 4 supporting the marking drum 5 rises, the limit switch 37 detects this and rotates the synchro motor 52a. The motor 52a stops instantly when the first slit plate 6 rotates one pitch of the slit. As a result, the marking drum 5 also rotates by one pitch, and the number 13 on the scale convex portion 53 is directed directly downward.

During the above operation, the synchronized motor 71a of the foil-covered tape winding device 7 rotates once, and the foil-covered tape T
Wind up one pitch.

The above operation is repeated every time the cloth 9 is fed 1 m, and numbers 13 to 0 are stamped with foil on the edges of the cloth every 1 m. When the length measuring device 8 finishes sending the signal 14 times, the feeding device 2 is activated by the first timer 38 to feed the cloth by 10 cm. Next, the slit 62 of the second slit plate 60
synchro motor 52 until it reaches the directly above position again.
a rotates, that is, the numbers 14 and 15 of the scale protrusion 53 that are not used for foil stamping pass directly below the position at high speed, and from the state where the number 13 reaches the position directly below, the same foil stamping operation as described above is repeated.

Pull out the cloth 9 that has been folded to the downstream side from above and use a separate process to stamp the 10 cm between the foil-stamped numbers 13 and 0.
If it is cut approximately at the center of the cutting allowance, the length of one unit of cloth will not be shorter than 13 m.

If the seam detector 88 detects a seam in the cloth while the cloth is being fed, the second timer 39 operates the feeding device 2 so that the cloth travels 30 cm. Between the seam detector 88 and the foil stamping drum 5
Since they are 20 cm apart, the cloth stops at a position where the seam passes 10 cm past the marking drum 5. At the same time, the synchronized motor 52a for driving the stamping drum rotates until the slit 62 of the second slit plate 60 reaches the position directly above, and the stamping starts again from the position where the number 13 is stamped. Therefore, some irregular length remains downstream from the seam of the cloth, but this can be removed when the cloth is cut. Therefore, it is possible to prevent seams from forming in the cloth wound as a unit.

In the example, numbers were stamped in descending order such as 13, 12, 11...2, 1, 0, but this is for the following reason.

The cloth cut into units is wrapped around a core material and shipped, but at that time the length of the cloth wrapped is required to be indicated on the outer edge of the cloth. 0, 1, 2...11,
When numbers are foil-stamped in ascending order such as 12 and 13, when the fabric folded into a bundle on the downstream side of the foil-stamping device is pulled up from above and cut at a predetermined position, if it is wound up in the pulling direction, one unit of fabric will be stamped. The number 0 is located at the outer edge of the cloth. In order to position the number 13 on the outside, when the cloth is cut, it must be wound in the opposite direction to the direction in which the cloth is pulled.
One more step is added and work efficiency is poor. On the other hand, if numbers are stamped in descending order like 13 to 0 as in the present application, the cloth can be wound up in the same tension direction when it is cut.

When cutting the cloth into 15m or 10m pieces, the slits 62 of the second slit plate 60 are cut into the first slit plate 6.
The key is to align the slits 62 of the second slit plate 60 with the slits 61 of the first slit plate 6 marked with the numbers 15 and 10 of the length you want to cut the cloth. Yes.

It goes without saying that the configuration of each part of the present invention is not limited to the above-mentioned embodiments, but can be modified in various ways within the technical scope of the claims for utility model registration.
