Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for intermittently transferring a film, paper, metal foil, composite paper or other sheet-like work for die cutting, cutting, and half-cutting to an intermediate position of thickness. In addition, the present invention relates to an anvil roller suitable for printing a sheet-like work, a working apparatus using the same, and a method of using the apparatus.

[0002]

2. Description of the Related Art For example, a composite paper consisting of a label paper on which necessary characters, figures, symbols, etc. are printed and having an adhesive layer on the back surface, and a release paper pre-attached on the back surface of the label paper is used as a work. The label paper of the work is punched out so that only the label portion having the required contour shape adheres and remains on the release paper, and the remaining portions of the label paper are separated and removed from the release paper. The work is sandwiched between the working roller and the anvil roller that are continuously rotated in synchronization with each other and continuously passed, and the work roller is provided on the peripheral surface of the working roller, for example, a flexible etching blade, an engraving blade, The blade edge of the punching blade that divides the required contour shape, such as the implanting blade, to the depth corresponding to the thickness of the label paper under the backup of the work with the anvil roller. It has been conventionally practiced to bite into the label and punch out the required label portion from the label paper.In this case, the remaining portion of the label paper, excluding the required label portion, is separated from the release paper and rolled. It is rolled and removed.

However, since this prior art technique allows the work to continuously pass between the continuously rotating work roller and the anvil roller, it is possible to realize high work efficiency. According to this, at least the circumference of the working roller, and by extension, the entire length of the punching blade disposed there over the entire circumference of the working roller, corresponds to one or a plurality of pitches of the printed label portion. Since it is unavoidable that other types of labels need to be punched for other types of labels that differ in the pitch length of the required label and the size of the label in the workpiece length direction, etc. It is necessary to prepare another working roller having a perimeter suitable for the part. Therefore, for punching of many kinds of label parts having different pitch lengths, etc. It is forced to prepare working rollers in the number corresponding to the class, this, equipment cost, there is an inconvenience that would result in an increase in such inventory management costs.

[0004]

For this reason, the work efficiency is unavoidably lowered, but in order to prevent an increase in the facility cost, inventory control cost, etc., the work is determined in accordance with the pitch length of the label portion, etc. Is intermittently transferred in units of length, and for each intermittent transfer, for example, by a magnetic attraction or the like attached to a work roller having a sufficiently long circumference, a flexible etching blade having a required length shorter than the roller circumference, It has been proposed to punch out the required label portion.

According to this proposed technique, one working roller having a sufficiently long circumferential length is magnetically attracted by various kinds of flexible etching blades prepared according to the type of the label portion, as required. Since one work roller itself can be used for punching of many kinds of label parts, it is possible to sufficiently realize the downsizing of the device based on the punching process with the pair of rotary rollers, as well as the equipment cost, etc. Can be effectively prevented from increasing, and mainly by changing the flexible etching blade to cope with punching of various label parts,
Since no large-scale setup change or the like is required, it is possible to make the work efficiency due to the intermittent feed of the work negligible, especially in the case of multi-type small-quantity machining.

By the way, in punching the label portion according to such a proposed technique, as shown in FIG. 9, for example, a work in which a flexible etching blade 101 having a required length is magnetically attracted to a peripheral surface thereof. Roller 102
And the anvil roller 103 that forms a pair with the roller 102.
Etching blade 10 in a state where and are continuously rotated.
Matching the timing of reaching the predetermined work position of 1,
Based on the operation of the pair of feed rollers 104, the work w is intermittently fed between the work roller 102 and the anvil roller 103 over a predetermined length, whereby the work w is moved around the etching blade 101. When the punching process is performed for the distance corresponding to the length in the direction, the feeding amount of the work w once is set to the flexible etching blade 101.
When the length is made substantially equal to the circumferential length of the flexible etching blade 10, as shown in FIG.
1 is started when the front end 101a of the flexible etching blade 101 in the rotating direction comes closest to the anvil roller 103, while the rear end 101b of the flexible etching blade 101 in the rotating direction of FIG.
As shown in FIG. 0, after the punching process is completed closest to the anvil roller 103, as shown in FIG. 11, a point at which the closest position is slightly passed, for example, a margin existing between required label portions. Almost the entire part is the rollers 10
It will be stopped at the time when it passes through the radial straight line position connecting the centers of 2, 103.

However, under such a stopped posture of the work w, the cutting edge of the rear end 101b of the etching blade 101 is still in the state of biting into the work w. If the working roller 102 and the anvil roller 103 forming a pair are continuously rotated, the work w is scratched or scraped by the edge of the etching blade 101, and the work w is damaged.

Therefore, the work w is based on the above-mentioned proposed technique.
In order to sufficiently prevent damage to the work w by performing intermittent feeding, the rear end 10 of the etching blade 101
It is necessary to feed a large amount of the work w to the position where 1b completely comes out of the work w, and in most cases,
An extra length of about half the circumference of the pair of rollers 102 and 103 is fed.

However, when the workpiece w is intermittently fed in this way, the next punching process for the workpiece w must be properly started at a predetermined position when the workpiece w is appropriately fed. It is necessary to pull back and displace the work w by the reverse rotation operation of the feed roller 104 until the predetermined start start point of the next processing for the above coincides with the work start position of the front end 101a of the etching blade 101. There is a problem that the existence thereof causes a reduction in punching work efficiency, complicates a mechanism such as a feeding drive unit and operation control, and makes it difficult to secure high processing accuracy.

The present invention has an object to solve such a problem of the proposed technique, and an object of the invention is to reduce the size of the device as an advantage brought about by the proposed technique. While preventing the increase in equipment cost, suppressing the decrease in work efficiency, etc., it is not necessary to feed extra work when intermittently feeding sheet-like work, and eventually pull back the extra work By eliminating the displacement process, the reduction of work efficiency due to the existence of the pull-back displacement process, complication of the mechanism such as the feed drive unit and operation control, difficulty of ensuring accuracy, etc. were sufficiently removed. Anvil Laura,
A working apparatus using the same and a method of using the apparatus are provided.

[0011]

An anvil roller according to the present invention forms a pair with a work roller, is continuously rotated in synchronization with the work roller, and is intermittently fed with a film, paper, metal foil,
A work roller provided with magnetic attraction or the like on a part of the peripheral surface of a composite paper or other sheet work, generally a long work, which can be a flexible etching blade or other punching blade. The work roller has a diameter of approximately the same as that of the work roller for backing up the work by the work roller by sandwiching the work roller between the work roller and the work roller provided on the work roller. A convex surface having a larger radial distance from the center of the roller than the other portions is provided near the rear side in the rotation direction of the portion corresponding to the rear end in the rotation direction.

By using the anvil roller as a pair with the working roller, for example, the work as described above,
When applying for punching label paper,
Under continuous rotation in synchronization with each other, the work is moved to the circle of the punching blade at the same timing as the front end of the punching blade on the working roller in the rotating direction reaches the predetermined working position. A distance approximately equal to the circumferential length, or more precisely,
Intermittent feeding between both rollers at a speed that is substantially equal to the roller peripheral speed by a distance that is the length of the blank area between required label areas added to the circumferential length of the punching blade. Allows the label paper to be punched as intended without scratching the work, and eventually to the label paper, without the need for extra feeding that requires pulling back the work.
It can be applied accurately without fear of damage such as scratching.

That is, when the work is intermittently fed in this way, the trailing end of the punching blade in the rotating direction comes closest to the anvil roller, so that one predetermined punching operation is completed and then the above-mentioned operation is performed. As described above, while the work is being fed by an amount equivalent to the blank distance between the label portions, the cutting edge of the trailing edge of the punching blade is under the action of the convex surface formed on the peripheral surface of the anvil roller. The work roller and the anvil roller are separated from each other after the intermittent feeding of the work is stopped because the work roller is completely disengaged from the work that has been bitten based on the displacement of the work roller from the center axis of the anvil roller. Even if continuous synchronized rotation is continued, damage to the work by the cutting edge of the punching blade can be sufficiently prevented.

Thus, according to this anvil roller,
When performing necessary processing such as punching while intermittently feeding the work, it is not necessary to feed the work more than the margin distance between the required label parts,
It is also unnecessary to pull back and displace the excessively fed work in order to perform the intended processing on the work.

The same applies to the case where the working means provided on the working roller is a printing plate, and the direction of rotation of the printing plate when the work is intermittently fed by a required minimum amount. It is possible to sufficiently prevent the rear end from being contaminated due to rubbing of the work by the escape displacement of the working roller provided with the printing plate with respect to the anvil roller.

Here, when the convex surface provided on the anvil roller is formed in a curved surface shape in which the protruding height is gradually changed at least in a part of the circumferential direction of the roller, the work roller of the working roller contacting the convex surface is Each of the escape displacement and the approach displacement with respect to the central axis of the anvil roller can be made sufficiently smooth to effectively prevent the occurrence of impact, vibration and the like due to the displacement of the work roller.

Further, when such a convex surface is provided at the portions corresponding to the flanges at both end portions of the work roller,
The convex surface can always function reliably without affecting the working means of the working roller arranged on the peripheral surface of the main body, and without being affected thereby. By the way, when the convex surface is provided only on the portion corresponding to the flange of the work roller, the formation area of the convex surface can be minimized if necessary.

The convex surface has a circumference of the working roller and
In relation to the circumferential length and the number of the working means arranged on the circumferential surface of the working roller, the working means may be provided at a plurality of places spaced in the circumferential direction.

Also, on the convex surface of the anvil roller,
When the means for adjusting the position in the circumferential direction with respect to the working roller is provided, the convex surface is provided at the rear end in the rotating direction of the working means according to the circumferential length of the working means arranged on the working roller. On the other hand, it is possible to always position the rear side so as to correspond accurately.

In this case, when the adjusting means is a member which is attached to the roller shaft of the anvil roller and engages and disengages with the gear for the working roller from the roller shaft, for example, a screw, the structure is simple. It is possible to easily adjust the circumferential position of the convex surface underneath.

Further, a working apparatus using an anvil roller according to the present invention is any one of the above-mentioned anvil rollers and a pair of the anvil rollers, is pressed against the anvil roller side, and is provided with working means on its peripheral surface. The work roller is provided with a feed roller pair that intermittently feeds the work over a predetermined length.

Here, the feed roller pair is intermittently operated with respect to the anvil roller and the working roller that are continuously rotated, and the timing is adjusted when the front end of the rotation of the working means provided on the working roller reaches the working position. Start feeding the work by the feed roller pair, and stop the feeding when the working means finishes the predetermined work and then feeds an extra distance corresponding to the margin between the required label portions. Then, in cooperation with the work roller and the anvil roller,
The intended work can always be done accurately.

This means that a pair of pulling rollers for exerting a required tension on the work passing between the anvil roller and the working roller are provided, and the pair of pulling rollers are also intermittently operated almost simultaneously with the pair of feed rollers. It is more effective when tension is constantly applied to the work during the displacement of the work.

Also in these cases, the convex surface provided closer to the rear side in the rotation direction than the portion of the anvil roller corresponding to the rear end of the rotation of the working means has the same structure as that of the working roller, as described above. Under the abutment of the convex surface there, because it causes the escape displacement in the direction away from the central axis of the anvil roller,
Without the need to feed excess work, the working means, especially the blade edge at the rear end of its rotation, can be completely removed from the work, and there is no risk of damage or stains on the work due to the insertion of the blade edge. It can be reliably removed, and the structure of the feeding mechanism and the like, operation control, etc. can be simplified, and high work accuracy can be realized.

In such an apparatus, one shared motor for driving each roller pair is provided, and in particular, each of the feed roller pair and the tension roller pair is directly or directly connected to the motor via at least one clutch. When indirectly connected, the structure of the device can be simplified and the size and cost of the device can be reduced as compared with the case where a plurality of motors are provided.

The method of using the working device using the anvil roller according to the present invention is such that when any one of the above-mentioned working devices is used, the work extending from between the pair of feeding rollers is intermittently moved by the pair of feeding rollers. The feeding is started in synchronism with the arrival of the working means provided on the continuously rotating working roller, and by extension, the front end of the turning direction of the working roller at the working position, and the intermittent feeding is started in the turning direction of the working means. When the trailing edge of the trailing edge slightly passes the position closest to the anvil roller, the trailing edge is stopped, and at this intermittent feed position, the working roller is displaced in a direction away from the central axis of the anvil roller, It is to bring out the complete escape from the work. According to this usage method, it is possible to surely realize the action and effect peculiar to the convex surface of the anvil roller.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an anvil roller according to the present invention in a combined posture with a work roller, in which 1 is a work roller and 2 is an anvil roller paired with the work roller 2, respectively.

Under the relation, it projects radially outwards by approximately the thickness of the working means. Further, here, such a working roller 1 and, by extension, the respective flanges 8
Is pressed against the anvil roller 2 by an urging means such as a spring 10 installed in the support frame 3.

Here, the work roller 1, particularly the main body portion 9 of the work roller, is made of, for example, a magnetically rigid material, and the required working means, for example, a flexible punching blade, is provided on the peripheral surface thereof. The printing plate, etc., can be magnetically attracted and fixed over the circumferential length within the range of the roller circumferential length, as illustrated in the side view of FIG. Here, this working means 11 is usually 0.3 to 0.8 mm.
The working roller 1 including the working means 11 has a body outer diameter equal to that of the anvil roller 2, and more preferably the peripheral speed from between the working means 11 and the anvil roller 2. By removing the difference, the forces exerted by the rollers 1 and 2 on the respective surfaces of the sheet-like work w are made substantially equal.

Here, when the working means 11 is mounted on the peripheral surface of the main body of the working roller 1, either the mounting start end position or the end position is always fixed on the peripheral surface of the working roller. Is preferable in order to facilitate the adjustment of the circumferential position of the anvil roller 2 in accordance with the position of the working means.
On the peripheral surface of the working means 11, a slit for inserting one of the ends of the working means 11 or other position restraining portion, or
It is preferable to provide a mark or the like for facilitating the positioning.

Further, here, the working roller 1 is paired,
With respect to the anvil roller 2 which holds the work w between the work roller 1 provided with the work means 11 on the circumferential surface, the two rollers 1, 1 are shown in FIG.
As shown in an enlarged view of a main part of a vertical cross section orthogonal to the central axis of 2, the portion 2b of the peripheral surface 2a corresponding to the rear end 11a in the rotating direction of the working means 11 is located on the rear side in the rotating direction. The radial distance R ₁ from the roller center O is
R ₂ becomes larger than the radial distance R of the other portion, and the convex surface 12 that abuts the flange peripheral surface of the work roller 1 is provided.

Here, the angular range θ in the circumferential direction of the formation area of the convex surface 12 is set to about 5 to 15 ° so that the convex surface 12 can effectively exhibit the intended function. In addition, each working means 1 having various circumferential lengths
On the other hand, it is preferable that the original backup function of the anvil roller is sufficiently exhibited.

More preferably here, the convex surface 12
Is a curved surface shape in which the amount of protrusion from the circumferential surface 2a gradually changes in the circumferential direction in at least a part of the circumferential direction of the roller, and preferably, as shown in FIG. It is provided only at the portion corresponding to the flange 8. According to the former, the contact impact of the convex surface 12 on the work roller 1 can be softened, and according to the latter, the work roller 1
The convex surface 1 without any effect on the body part 9 of the
The formation area of 2 can be made the minimum necessary. Therefore, in FIG. 3, the convex surface 12 provided only on the portion corresponding to the flange 8 has a triangular mountain shape as a whole, and the apex thereof has a curved surface shape.
Can have a curved surface as a whole.

By the way, the formation of such a convex surface 12 on the anvil roller 2 is performed here by fastening a block 13 provided with the convex surface 12 in advance into a notch of the roller main body with a bolt. However, instead of this, the convex surface 12 can also be formed by overlaying or spraying the roller body.

It should be noted that the convex surface 12 as described above has a plurality of intervals in the circumferential direction of the anvil roller 2 in relation to the number of surfaces of the applied working means 11 on the circumferential surface of the working roller. It can also be formed at a portion, and according to this, the cycle time of intermittent feeding by the feed roller pair can be shortened according to the number of convex surfaces.

Further, as shown in FIG. 1, in order to make it possible to properly adjust the circumferential relative position of the convex surface 12 thus provided on the anvil roller 2 with respect to the circumferential surface of the working roller 1. , Attached to roller 2,
A bolt or other screw member 14 for fixing and separating the gear 7 meshing with the gear 6 fixed to the working roller 1 from the roller shaft 5 is used as the position adjusting means of the convex surface 12.
By loosening the screw member 14 and freeing the gear 7 with respect to the roller shaft 5, the relative rotational displacement of the anvil roller 2 is allowed, while the screw member 14 is tightened to move the gear 7 to the roller. By fixing to the shaft 5, the anvil roller 2
Restrains the relative rotational displacement with respect to the gear 7.

In the relative rotation of the anvil roller 2 and, by extension, the convex surface 12, the location specified in relation to the circumferential length of the working means 11 applied to the working roller 1 is specified. In order to simply and accurately rotate only a fixed amount, the shaft fixing ring 15 side fixed to the roller shaft 5 and rotated together with the convex surface 12 and the gear 7 that meshes with the gear 6 and is not rotationally displaced. It is preferable to provide a scale 16 on one side and a mark 17 indicating the rotation amount on the other side between the side and the side.

FIG. 2 is a partial cross-sectional schematic line side view illustrating a working apparatus using the anvil roller as described above, which is a pair of the working roller 1 and the anvil roller 2.
With regard to (1) and (2), a pair of feed rollers 21 for intermittently feeding the sheet-like work w over a predetermined length between them.
And a desired tension is applied to the work w sandwiched between them and passed between the work roller 1 and the anvil roller 2, preferably, a pair of pulling rollers having a slightly higher peripheral speed than the feed roller 21. 22 is provided.

Here, at least one of these roller pairs is arranged so as to be biased toward the upper side or the lower side in the figure with respect to the rollers 1 and 2, and the work w is transferred to the roller 1 or the roller 2. The contact length can be increased, and the meandering of the work w can be advantageously restrained.

With respect to the roller pair thus arranged, preferably one motor for driving each roller pair is provided, and each of the feed roller pair and the tension roller pair is
It is connected to the motor via at least one clutch.

FIG. 4 is a schematic line side view showing an example thereof.
FIG. 4A shows that one motor M is connected to one of the pair of rollers 1 and 2 under the meshing of the gears 6 and 7 by a transmission means 23 such as a belt or a chain, and the other common transmission is performed. By means 24, each of the feed roller pair and the pull roller pair is also directly connected in the same manner.

Under such a connection mode, when the pair of rollers 1 and 2 are continuously rotated while the pair of feed rollers and the pair of pulling rollers are intermittently rotated, Each of the pulling roller pairs,
It is necessary to connect and disconnect with the motor M using each clutch.

In FIG. 4 (b), one motor M is connected to the rollers 1 and 2 and the feed roller pair by the transmission means 25, and the feed roller pair is connected to another transmission means 26.
Is connected to the pair of pulling rollers by.

According to this, the pulling roller pair can also be simultaneously connected / disconnected to / from the motor M by connecting / disconnecting the motor power under the action of the clutch 27 provided on the feed roller pair side. So with one clutch,
It is possible to control the intermittent rotation of both roller pairs. In addition,
Reference numeral 28 in the drawing schematically shows a brake.

With the working apparatus configured as described above, for example, for a sheet-like long work which is a composite of label paper and release paper, only the required label portion is attached and remains on the release paper. When performing a punching process, the working means 11 may be, for example, a flexible etching blade, which is a punching blade having a required length, and the punching blade 11 is used as a work piece as illustrated in FIG. The front end of the roller 1 in the rotating direction is magnetically adsorbed and disposed on the peripheral surface of the main body of the roller 1, and the anvil roller 2 is provided.
The relative position in the circumferential direction of the convex surface 12 of the is adjusted so that it is located close to the rear side of the rear end 11a in the rotating direction of the punching blade 11, as described above. To do.

While continuously rotating the rollers 1 and 2 as described above under the action of the motor M, the work w supplied between them is sandwiched between the rollers 1 and 2, and the work w is When making the required punching process by making the edge of the punching blade 11 bite into the label paper of
When the front end of the punching blade 11 on the work roll 1 in the rotating direction reaches the work position thereof, for example, the position closest to the anvil roller 2, the feed roller 21 shown in FIG. The work w is intermittently operated to feed the work w between the rollers 1 and 2 by a length substantially equal to the circumferential length of the punching blade 8, and together with this feeding, the pulling roller 22
Is also intermittently operated to apply a sufficient tension to the work w for smooth and reliable punching.

FIGS. 5 and 6 are sectional views showing the starting state and the progressing state up to the middle of the punching process accompanying the feeding of the work w, respectively. The punching process is shown in an enlarged sectional view in FIG. As described above, the punching blade 11 ends when the trailing end 11 a in the rotating direction comes closest to the anvil roller 2. On the other hand, the feeding of the work w is stopped when the punching process is completed, and as shown in FIG. 7, the workpiece is fed further by the distance δ corresponding to the margin between the required label portions. Then, the pulling roller 22 is also stopped.

In this apparatus, both rollers 1 and 2 continue to rotate even after the feeding of the work w is stopped, but here, the distance of the work w after the punching is completed. During the extra feed over δ,
As shown in FIG. 7, the convex surface 12 of the anvil roller 2 is
By contacting the peripheral surface of the flange of the work roller 1, the flange 8, and thus the work roller itself, is displaced and displaced in the direction away from the central axis of the anvil roller 2 against the pressing force of the spring 10. Since the cutting edge of the trailing end 11a of the punching blade 11 that has cut into the work w is completely extracted from the work w, the continuous rotation thereafter of the pair of rollers 1 and 2 is Since the work is performed without affecting w, the damage of the work w by the punching blade 11 can be sufficiently prevented.

On the other hand, when the convex surface 12 is separated from the work roller 1 as the rollers 1 and 2 rotate, the work roller 1 returns to its original position based on the pressing force of the spring, and this return state is set. Below, the working roller 1 rotates under the contact of the flange peripheral surface with the anvil roller peripheral surface 2a. Therefore, by selecting the projection amount of the work roller flange 8 from the main body portion 9 to be slightly larger than the thickness of the punching blade 11, for example, the work for the work w by the punching blade 11 is performed as intended. In addition, the relative rotation of the rollers 1 and 2 with respect to the work w for which the intermittent feeding is stopped is performed in the presence of the clearance between the peripheral surface of the anvil roller and the main body portion 9 of the work roller 1. It can be smoothly performed without any hindrance, and the punching blade 11 can start the same punching processing as described above when it reaches the working position again.

FIG. 8 is an enlarged side view showing another mode of forming the convex surface. In this figure, the convex surface 12 is mainly composed of an arc curved surface portion 12a which is concentric with the central axis of the anvil roller 2, and is first described. The circumferential length of the curved surface portion 12a is considerably longer than that of the convex surface described above, and the curved surface portion 12a is
At both ends in the circumferential direction of the respective inclined surfaces 12b and 12
It is formed so as to be smoothly continuous with the roller peripheral surface 2a via c. In addition, here, each inclined surface 12b
It is also possible to make at least one of and 12c a curved shape.

It goes without saying that the convex surface 12 thus formed can also function in the same manner as described above, but according to this example in which the circumferential length of the curved surface portion 12a is increased, the roller 1 In combination with the control of the rotation speeds of 2 and 2, it is possible to more sufficiently reduce the vibration or impact caused by the displacement of the work roller 1.

[0053]

As described above, according to the present invention, under the action of the anvil roller having a simple structure, the work means arranged on the work roller is stopped for the work to be intermittently fed by a required amount. The work roller and the anvil roller can be separated from each other without damaging the work without feeding the surplus work, and thus withdrawing and displacing the work. It is possible to continuously rotate without leaving, and at the same time, it is possible to simplify the mechanism such as the feeding drive unit and the operation control, and to realize high processing accuracy.
