Description

BACKGROUND OF THE INVENTION

The present invention relates to a printing device, wherein, with respect to a duplicator of the printing device, the number of ink rolls to be interposed between a bottling roll for supplying ink and an application roller for applying ink onto a printing impression roll is reduced; the ink is thereby rapidly supplied to the printing impression roll, the scattering of ink adhering to each of the rolls and the heating of each of the rolls are restricted to a minimum, and the color of ink to be supplied can be changed with ease; and with respect to the duplicator having a reciprocating printing impression roll, the construction is made to properly adjust for the error of the printing position which occurs due to the deviation of a printing paper sheet generated during contact of the impression face of the printing impression roll with the printing paper sheet, the friction resistance during contact of the printing impression roll with the printing paper sheet to perform forward or backward movement, the fact that the printing paper sheet is not properly supplied and arranged at a specified place on a base stand and the like; the detachment of an upper chase plate can be performed safely and with ease in a die cutting device for punching labels, seals and the like in which a pattern or letters is suitably printed on paper or film by the duplicator without cutting the peeling sheet, with respect to a punched residue winding device, while allowing continuous punched residue generated when a product is suitably and continuously punched from a strip-shaped printed article which is not to be cut, it becomes possible to tightly wind by performing the so-called surface winding to securely reel the continuous punched residue without loss, and if the punched residue is cut, a reeling device for reeling the residue and a device in an upstream step thereof are immediately stopped, and control is made extremely simple, rapid, and accurate so as to make the printing state of the strip-shaped printed article and the downstream processing state by a downstream step processing device to be regular within an acceptable range in relation to the printing device.

Prior art

With respect to a printing device comprising a duplicator for performing intermittent printing onto a strip-shaped article subjected to printing supplied from a paper supply device using a printing impression roll which performs positive or reversed rotation when performing forward or backward movement in a direction perpendicular to a transmission direction of the strip-shaped article subjected to printing; a die cutting device for punching a strip-shaped printed article printed by the duplicator into a suitable shape; and a punched residue winding device for winding a punched residue after punching by the die cutting device; in the case of the duplicator, an application roller for applying ink during the forward step onto a printing impression face of the printing impression roll which performs positive or reversed rotation while performing forward or backward movement, and an application roller for applying ink during the backward step, are allowed to contact each of the individual ink rolls which rotate in the reverse direction with respect to the rotation direction of each of the application rollers, so as to adhere ink onto each of the application rollers; and in the conventional duplicator, for example, as shown in Figs. 5A, 5B, and 5C, a plurality of ink rolls are interposed between a bottling roll 46 for sending ink from an ink tank 45 and the application roller 48 for applying ink onto the printing impression roll 47.
By disposing such a plurality of ink rolls therebetween, the adhesion of ink onto the application roller for applying ink onto the printing impression roll has been equalized.
According to US-A-4 691 630, a printing device similar to that described above is disclosed having:

a printing impression roll which is movable forwards while rotating in one direction and backwards while rotating in an opposite direction, along a line perpendicular to a direction of feeding a strip-shaped article subjected to printing to be fed from a paper supply device, such that printing on the article subjected to printing is performed intermittently during the forward and backward movements of said printing impression roll;
a pair of ink rolls which are provided above said printing impression roll at a distance therefrom in parallel with a shaft of said printing impression roll;
a pair of application rollers which are swung to bring them into alternate contact with said printing impression roll and said pair of ink rolls, whereby an ink is applied by said ink rolls to a printing impression of said printing impression roll;
a roll train having a bottling roll, an access roll and kneading rolls, all of said rolls coming into consecutive contact with each other; and an ink tank disposed above said roll train in contact with a peripheral surface of said bottling roll, whereby the ink contained in said ink tank is fed to said ink rolls via said roll train.

In contrast, with respect to a duplicator in which a printing impression roll is allowed to perform positive or reversed rotation with forward or backward movement, and in which a printing paper sheet is intermittently supplied and stopped by a certain length in a direction perpendicular to the forward or backward movement direction to perform printing, a phenomenon has occurred in which the printing paper sheet deviates slightly during contact of the printing impression roll with the printing paper sheet.
The applicant has made various improvements for devices for adjusting such deviation of the printing paper sheet, and for example, has filed a patent application as Japanese Patent Application No. 59-162505.
This patent application applies to a duplicator having a reciprocating printing impression roll which is formed such that a rack mechanism is formed in parallel with the moving direction of a reciprocating printing impression roll, a gear is attached to one end of a rotation shaft of the printing impression roll, and the gear is allowed to engage with a rack of the rack mechanism; thereby the printing impression roll is allowed to perform positive or reversed rotation in accordance with the reciprocating movement; characterized in that an operation control mechanism is arranged for controlling operation of the above-mentioned printing impression roll; the operation control mechanism comprises a preceding positive or reversed rotation mechanism which permits rotation in which the positive or reversed rotation in accordance with the reciprocating movement of the above-mentioned printing impression roll is faster than the standard positive or reversed rotation when the engagement of the above-mentioned gear with the rack of the rack mechanism is the engagement of a standard gear with a standard rack engaging therewith, and a slip driven rotation mechanism which rotates the printing impression roll to slip the forced positive or reversed rotation to simulate the rotation due to the engagement of the abovementioned gear with the rack of the rack mechanism to some extent when the printing impression roll is applied with forced positive or reversed rotation force to rotate faster than the standard positive or reversed rotation; the above-mentioned rack mechanism is formed such that a first rack and a second rack arranged in parallel are allowed to approach or contact so as to simultaneously engage the above-mentioned gear with the first rack and the second rack; tooth grooves of the first rack and the second rack are formed to have a groove width wider than that of the standard rack; the formation is made to suitably deviate phases of the tooth grooves of the first rack and the second rack; the formation is thereby made such that an engagement state of simultaneous engagement of the gear with the first rack and the second rack is controlled to give forced positive or reversed rotation so as to slightly precede the rotation in accordance with the reciprocating movement of the printing impression roll with respect to the above-mentioned standard positive or reversed rotation.
Furthermore, the present state of the art in the printing device with respect to the control of a printing state of the strip-shaped printed article and a downstream processing state by the downstream step processing device is such that trial printing is performed several times, a skilled person observes it visually so as to judge whether the error is within an acceptable range or exceeds the range, and correction is made by manual work in accordance with the perception of the skilled person.
Additionally, a die cutting device in such a printing device is formed to have a sliding mechanism for detaching its upper chase plate in which, between an upper frame and a lower frame of the die cut of the printing device, items such as labels, seals and the like are inserted into the upper chase plate made of thick steel attached with a punching blade at its lower face in a detachable manner via suitable rails at both sides in a manner simply capable of free insertion and detachment in forward and rearward directions, and when the punching blade is exchanged or the punching blade is inspected, the upper chase plate is slid forwardly to once remove the upper chase plate from the rails, and thereafter the upper chase plate is turned.
In addition, a printing production device for labels and the like is provided for various markets in which a strip-shaped printed article on which a pattern or letters is continuously and suitably printed by a duplicator, is suitably and continuously punched by a die cutting device at a portion containing the pattern or letters as a predetermined product in the next step, and such a printing production device for labels and the like is necessarily added and provided with a punched residue winding device after punching the product with respect to the strip-shaped printed article as having a reeling device for automatically winding the continuous punched residue generated during the operation period.
Such a punched residue winding device has a general structure in which the continuous punched residue, after suitably and continuously punching a predetermined product from the strip-shaped printed article by means of the die cutting device, is simply and automatically wound by means of the reeling device.
However, in the conventional duplicator, with respect to its ink supply mechanism, a plurality of ink rolls is interposed between the bottling roll for supplying ink and the application roller for applying ink onto the printing impression roll, and it has therefore taken a long time to allow ink to arrive at the printing impression roll from the ink tank.
In addition, a plurality of ink rolls rotate, so that ink adhered to each of the rolls has scattered. At the same time, a plurality of ink rolls are in rotating abutment, so that each of the ink rolls has been easily heated.
Furthermore, because of the presence of a plurality of ink rolls therebetween, a plurality of ink rolls should be exchanged when the color of the ink is changed, and it has taken a long time to do the exchanging work or washing work for the roll.
In addition, in the patent application in relation to the above-mentioned Japanese Patent Application No. 59-162505, although the deviation of the printing paper sheet generated during the contact of the impression face of the printing impression roll with the printing paper sheet can be adjusted, it has been impossible to adjust the deviation of the printing paper sheet generated during the reciprocating movement on the printing paper sheet after the contact of the printing impression roll with the printing paper sheet.
This deviation of the printing paper sheet occurs due to frictional resistance during reciprocating movement with the contact of the printing impression roll with the printing paper sheet, and due to the fact that the printing paper sheet is not accurately supplied and arranged at a specified place on a base stand and the like.
As a result, for example, when a printed portion is punched by a press machine or the like after the completion of printing during the production of labels and the like, the print position deviates from a predetermined position, -so that problems have occurred in which the pattern of a label or the like cannot be accurately punched during the punching process.
In addition, in order to avoid such a situation, a lock bolt which fixes the printing impression roll and its gear is loosened, and the change of the phase of the printing impression roll must be set by manual rotation; the adjustment of the contact face between the impression face of the printing impression roll and the printing paper sheet has therefore been extremely troublesome.
Furthermore printing operation should be interrupted one by one so as to perform such an adjustment, and this has consumed time in the printing operation.
On the other hand, with respect to the printing device, in relation to the control of the printing state of the strip-shaped printed article and the downstream processing state by the downstream step processing device, a long time is required for correction, even in the case of being performed by a skilled person, or the correction cannot be made accurately due to dependency on the perception of the operator, or the labor costs become high because of the requirement of a skilled person; therefore, it has been regarded as completely impossible to contemplate lowering the cost of printing, which has been a large problem in printing work.
In addition, with respect to the die cutting device, due to a combination of the facts that the punching blade is attached to the lower face of the upper chase plate and the upper chase plate is made of thick steel, the upper chase plate is extremely heavy, and it is therefore troublesome to exchange the punching blade or inspect the punching blade, and there is a fear of accidental dropping, which is extremely dangerous.
Furthermore, in the case of the structure of the abovementioned punched residue winding device, the continuous punched residue is highly likely to be cut, and the punched residue itself is a strip-shaped article after the punching of the product, so that it is cut during winding, or it is almost impossible to tightly wind, and the continuous punched residue cannot be wound in a regular manner, resulting in occurrence of various inconveniences.

- said ink tank and said roll train are mounted on said sliding base stand ;
- said roll train comprises said bottling roll whose peripheral surface is in contact with said ink tank, said access roll whose peripheral surface is in contact with said bottling roll, a fixed metallic roll whose peripheral surface is in contact with said access roll, a first kneading roll whose peripheral surface is in contact with said metallic roll, and a second kneading roll whose peripheral surface is in contact with said first kneading roll ; and
- the contact between said first kneading roll and said second kneading roll of said roll train with said ink rolls is separated by the movement of said sliding base stand.

Preferably, the ink tank and the bottling roll are installed on the sliding base stand in a detachable manner.
More preferably, the printing device comprises a further second slinding base stand, with a second ink tank and roll train mainted thereon.
Additionally, the problem of the above-mentioned task is solved in accordance with the fact that with respect to the printing device, the duplicator is constituted to have the printing impression roll of forward or backward movement which is formed such that a rack mechanism is formed in parallel with the movement direction of the printing impression roll which performs forward or backward movement, a gear is attached to one end of a rotation shaft of the printing impression roll, and the printing impression roll is allowed to perform positive or reversed rotation in accordance with the forward or backward movement by engaging the gear with a rack of the rack mechanism, a preceding positive or reversed rotation mechanism is arranged such that the positive or reversed rotation in accordance with the forward or backward movement of the printing impression roll is made to have faster rotation than the standard positive or reversed rotation in which the engagement of the gear with the rack of the rack mechanism is regarded as the engagement of a standard gear with a standard rack engaging therewith, the rack mechanism is formed such that a first rack and a second rack arranged in parallel are allowed to approach or contact so as to simultaneously engage the gear with the first rack and the second rack, tooth grooves of the first rack and the second rack are formed to have a groove width which is wider than that of the standard rack, the formation is made to suitably deviate phases of the tooth grooves of the first rack and the second rack, and thereby the formation is made such that an engagement state of simultaneous engagement of the gear with the first rack and the second rack is controlled to give forced positive or reversed rotation so as to slightly precede the rotation in accordance with the forward or backward movement of the printing impression roll with respect to the standard positive or reversed rotation, and the rack mechanism is constituted in a manner capable of movement in the forward or backward movement direction of the printing impression roll.
The problem of the above-mentioned task is solved in accordance with the fact that with respect to the printing device, in relation to the punched residue winding device, a reeling device for the punched residue is constituted by a reeling roller which performs driving and rotation and a reeling auxiliary roller which is arranged in a substantially parallel manner closely adjacent to the reeling roller, the reeling roller is formed so as to wind at a speed faster than a printing speed by the duplicator by a certain ratio, the formation is made to apply pressure in a direction to abut against the reeling auxiliary roller by its own weight or suitable urging force, and the formation is made to allow the continuous punched residue to pass between the reeling roller and the reeling auxiliary roller so as to wind around the reeling roller.
The problem of the above-mentioned task is solved in accordance with the fact that with respect to the punched residue winding device, the continuous punched residue to be wound by the reeling roller has one face as an adhesive adhering face, and the construction is made such that winding is performed allowing the adhesive adhering face to contact with the peripheral surface of the reeling roller.
Furthermore, the problem of the above-mentioned task is solved in accordance with the fact that with respect to the punched residue winding device, a residue cut detecting bar which is arranged to give tension which does not cause cutting of the punched residue by means of its own weight or urging force is provided between a guide roller arranged at a rearward portion from the die cutting device and the reeling device for reeling the punched residue arranged at a rearward portion from the guide roller, and the formation is made such that when the repulsive resistance from the punched residue ceases in a state of giving tension to the punched residue by means of the residue cut detecting bar, the entire apparatus including the die cutting device and the reeling device is immediately stopped.
In the printing device according to the present invention, in relation to the duplicator thereof, when the ink is supplied from the ink tank to the ink roll via the bottling roll, the access roll, the fixed metal roll, and the kneading roll, the kneading roll is rotated at a high speed so as to adhere the ink onto the kneading roll, the ink roll, and the fixed metal roll to circulate it; thereby the adhesion of ink onto the application roller is made uniform.
In addition, to the sliding base stand are fixed the bottling roll for sending ink from the ink tank, the access roll which rotates with the support arm to suitably abut against the bottling roll, and the fixed metal roll and the kneading roll for adhering ink supplied by the bottling roll and the access roll onto the ink roll, the sliding base stand is suitably moved to allow the kneading roll to abut against the ink roll, and the kneading roll is rotated at high speed so as to adhere the ink onto the kneading roll, the ink roll, and the fixed metal roll to circulate it.
When the color of the ink is changed, the ink supply body is removed, an ink tank provided with ink having a predetermined color is installed onto the ink supply body, and this ink supply body is installed onto the sliding base stand.
In addition, in the printing device according to the present invention, at first, assuming that the printing paper sheet does not deviate when the printing paper sheet contacts with the printing impression, the positional relationship between the gear of the printing impression roll and the rack mechanism is set so as to provide printing at a regular position. While maintaining the second rack of the rack mechanism to be fixed, the first rack is moved, and the phase of the tooth for the first rack and the second rack is deviated. At this time, the tooth grooves of the first rack and the second rack are made to have a groove width wider than the tooth groove of the standard rack so as to allow slack beforehand, so that the phase of the tooth for the first rack and the second rack is deviated, thereby the tooth groove becomes narrow to approach the width of the tooth groove of the standard rack.
At a position after the approach toward the tooth groove of the standard rack to some extent, the first rack is fixed, and the printing impression roll is allowed to perform forward or backward movement.
At this time, the preceding positive or reversed rotation mechanism is arranged at one end of the rotation shaft, so that the gear has the engagement between the gear and the rack mechanism which always performs preceding rotation to a degree of slack, and for example, when the printing impression roll 1 moves from the left to the right, the teeth of the gear abut against the left side of the rack tooth groove, that is, the rearward side with respect to the moving direction of the gear so as to engage with the rack mechanism. Therefore, the rotation of the printing impression roll in this case always maintains a preceding state with respect to the standard rotation of the printing impression roll rotating in accordance with the forward or backward movement with the engagement between the rack having the regular groove width and the gear.
As described above, the degree of deviation of the printing paper sheet toward the forward direction of the movement of the printing impression roll during the contact between the printing paper sheet and the printing impression of the printing impression roll is offset by allowing the preceding rotation beforehand with respect to the standard rotation of the printing impression roll.
In addition, the deviation of the printing paper sheet which occurs due to the frictional resistance during the forward or backward movement with the contact of the printing impression roll with the printing paper sheet after the contact of the printing impression roll with the printing paper sheet, the fact that the printing paper sheet is not accurately supplied and arranged at a specified place on the base stand and the like is offset by moving the rack mechanism toward the forward or backward movement direction of the printing impression roll. That is, when the rack mechanism is moved in the forward or backward movement direction of the printing impression roll, the printing impression roll also rotates via the gear in accordance with the moving action, so that the contact face between the printing paper sheet and the printing impression of the printing impression roll is adjusted using the rotation of the printing impression roll in accordance with the movement of the rack mechanism.
Furthermore, the punched residue winding device after the punching of the product in the printing device according to the present invention is formed such that with respect to the punched residue winding device after the punching of the product for the strip-shaped printed article in which the strip-shaped printed article continuously and suitably printed with a pattern or letters by the duplicator is subjected to suitable and continuous punching using the die cutting device in the next step at the portion containing the pattern or letters as a predetermined product; and there is provided the reeling device for automatically winding the continuous punched residue generated during the period, the reeling device being constituted by the reeling roller which performs driving and rotation, and the reeling auxiliary roller which is arranged substantially parallel closely adjacent to the-reeling roller; the reeling roller being formed to apply pressure in the direction to abut against the reeling auxiliary roller by its own weight or suitable urging force, so that when the above-mentioned continuous punched residue is allowed to pass between the reeling roller and the reeling auxiliary roller so as to wind around the reeling roller, the continuous punched residue is wound around the winding roller while pressure is being applied by the winding auxiliary roller, so that it is wound tightly.
Moreover, at this time, the construction is made with respect to the winding speed by the reeling roller so as to wind at a speed faster than a printing speed by the duplicator by a certain ratio, so that the continuous punched residue is always wound in a state of tension, and it is wound tightly and reeled in a regular manner.
The continuous punched residue to be wound by the reeling roller has as one face an adhesive adhering face, and the formation is made such that winding is performed while allowing the adhesive adhering face to contact the peripheral surface of the reeling roller, so that when it is tightly wound in a regular manner to yield a rolled state, the so-called surface winding state is obtained, so that no winding deficiency due to the adhering force of the adhesive results, which is extremely convenient for handling.
Furthermore, tension to an extent which does not cause cutting is given to the above-mentioned punched residue by means of the weight of the residue cut detecting bar itself or the urging force, thereby when the punched residue is cut, the repulsive resistance from the punched residue disappears when giving tension to the punched residue by the residue cut detecting bar, so that the entire apparatus including the above-mentioned die cutting device and the reeling device is stopped, so as to prevent deficiency of treatment which may produce winding deficiency and a disordered state of the punching reside as generated when the punched residue is cut.

PREFERRED EMBODIMENTS OF THE INVENTION

An example of the present invention will be explained hereinafter on the basis of the drawings.
As shown in Fig. 1, a printing device 1 according to the present invention comprises a duplicator 3 which performs intermittent printing onto a strip-shaped article subjected to printing S1 supplied from a paper supply device 2 using a printing impression roll which performs positive or reversed rotation while performing forward or backward movement in a direction perpendicular to a sending direction of the strip-shaped article subjected to printing S1, an image processing mechanism 7 which detects and corrects deviation of a printing position of a printed article and the like, a laminating mechanism 4 which laminates a transparent adhesive film onto a print face of the printed strip-shaped printed article S2, a die cutting device 5 which punches the strip-shaped printed article S2 printed by the duplicator 3 into a suitable shape, a punched residue winding device 6 which winds a punched residue A after punching by the die cutting device 5, and a product winding device 8 which winds the punched product. In the figures in this case, it is not shown that in the rearward direction of the duplicator 3, a drying mechanism is arranged for drying ink printed by the duplicator 3.
The above-mentioned duplicator 3 comprises a bottling roll 13 for sending ink from an ink tank 12, an access roll 15 which rotates with a support arm 14 to suitably abut against the bottling roll 13, and a fixed metal roll 18 and a kneading roll 19 for adhering ink supplied by the bottling roll 13 and the access roll 15 onto ink rolls 16 and 17 as an ink applying device 11.
The access roll 15 which constitutes the ink applying device 11 has such a structure that it abuts against the bottling roll 13 when it tilts upward, and it abuts against the fixed metal roll 18 when it tilts downward. In addition, the kneading roll 19 which abuts against the fixed metal roll 18 comprises two rolls 20 and 21 which rotate while being provided with a driving device. The two rolls which constitute the kneading roll 19 abut against the ink rolls 16 and 17 and supply ink to the rolls 16 and 17.
The ink applying device 11 shown in Fig. 1 is constituted such that to a sliding base stand 24 attached in a manner capable of sliding in the horizontal direction via a rail 23 arranged in the lateral direction of a duplicator main body 22 are fixed the bottling roll 13 for sending ink from the ink tank 12, the access roll 15 which rotates with the support arm 14 to suitably abut against the bottling roll 13, and the fixed metal roll 18 and the kneading roll 19 for adhering ink supplied by the bottling roll 13 and the access roll 15 onto the ink rolls 16 and 17.
As shown in Fig. 2, the two sliding base stands 24 and 25 are attached to the rail 23, and when the ink tanks 12 for different colors are installed on each of the sliding base stands 24 and 25, then the sliding base stands 24 and 25 are suitably slid, and inks having different colors can thereby be easily supplied to the ink rolls 16 and 17.
In addition, when an ink supply body 26 comprising the ink tank 12 and the bottling roll 13 is installed on the sliding base stands 24 and 25 in a detachable manner, inks having different colors may be optionally supplied with ease. For example, as shown in Fig. 3 and Fig. 4, this ink supply body 26 is constituted by installing the ink tank 12 which has a box shape having its bottom plate inclined and one side wall in an open state onto a base frame body 27 provided with the bottling roll 13. The base frame body 27 fixes both side walls 29 and 30 through a bottom plate 28, and 4 bottling rolls 13 are arranged between both side walls 29 and 30. In addition, the base frame body 27 is attached with handles 31 and 32 in order to make transportation thereof easy in a manner capable of free rotational movement.
On the other hand, as shown in Fig. 3, a side wall 33 of the ink tank 12 is cut out so as to substantially form a circular arc, so as to abut against a rotation shaft 34 of the base frame body 27 which supports the above-mentioned bottling roll 13 by a shaft to allow the peripheral surface of the bottling roll 13 to enter into the ink tank 12. Owing to such a constitution, the ink in the ink tank 12 is sufficiently adhered to the rotating bottling roll 13. when the ink tank 12 is installed on the base frame body 27, a stopper 35 which is attached to the bottom plate of the ink tank 12 abuts against the bottom plate 28 of the base frame body 27 to be fixed at a predetermined position.
Printing onto the strip-shaped article subjected to printing 51 placed on a printing pressurizing stand 36 is performed by rotating and pressurising a predetermined printing impression roll 38.
This printing impression roll 38 proceeds leftwardly from a position shown in Fig. 2 (continuous line) while performing counter-clockwise rotation. A printing impression face of the printing impression roll 38 contacts the strip-shaped article subjected to printing 51 which stops after being supplied by every certain length in a direction perpendicular to the proceeding direction of the printing impression roll 38 on the printing pressuring stand 36 so as to perform the first printing.
The printing impression roll 38 further proceeds leftward (two-dot chain line in Fig. 2), which arrives at the left end and changes its rotation direction into the clockwise direction to begin proceeding in the right direction. After the printing impression roll 38 has made the first printing onto the strip-shaped article subjected to printing S1, the strip-shaped article subjected to printing S1 is subjected to paper supply by a predetermined length and stops again, and the printing impression face of the printing impression roll 38 proceeding from the left end contacts this strip-shaped article subjected to printing S1 to perform the second printing and returns to the position shown in Fig. 2 (continuous line).
In the meantime, an application roller 39 abuts against the printing impression face of the printing impression roll 38 when the.printing impression roll 38 proceeds from the r right end to the printing position (continuous line in Fig. 2), and the ink is applied onto the printing impression face while performing upward movement.
At this time, since the printing impression roll 38 rotates counter-clockwise, the application roller 39 which abuts thereagainst applies ink while rotating clockwise, and the application roller 39 performs rotational movement together with its support arm 40 upwardly during the period of proceeding of the printing impression roll 38 to the central printing position to be lifted up to a position for abutting against the ink roll 16, which abuts against the ink roll 16 rotating counter-clockwise (two^∼dot chain line in Fig. 2). Therefore, while maintaining the initial clockwise rotation of the application roller 39, the ink is smoothly applied onto the printing impression face.
During the period in which the printing impression roll 38 completes the first printing onto the strip-shaped article subjected to printing S1 and proceeds to the left end of the duplicator main body 22, the strip-shaped article subjected to printing S1 is supplied by a certain length and stops. When the printing impression roll 38 arrives at the left end of the duplicator main body 22, another application roller 41 performs rotational movement together with a support arm 42 downward to abut against the printing impression roll 38 (two-dot chain line in Fig. 2). When the printing impression roll 38 starts proceeding from the left end of the duplicator main body 22 toward the central direction, the printing impression roll 38 rotates clockwise opposite to the case of the first printing.
Therefore, the application roller 41 which abuts against the printing impression roll 38 applies ink onto the printing impression face while rotating counter-clockwise opposite to the printing impression roll 38, and the application roller 41 performs rotational movement upwardly together with the support arm 42 during the period of proceeding of the printing impression roll 38 to the central printing position to be lifted up to a position to abut against the ink roll 17 (continuous line in Fig. 2). At this time, the ink roll 17 which abuts against the application roller 41 rotates clockwise opposite to the application roller 41. Therefore, the application roller 41 lifted upward while rotating counter-clockwise abuts against the ink roll 17 rotating clockwise, so that the ink is smoothly applied while maintaining the initial rotation of the application roller 41.
The ink rolls 16 and 17, which supply ink to these application rollers 39 and 41, rotate while abutting against the kneading roll 19 respectively. That is, the roll 20 of the kneading roll 19 which abuts against the ink roll 16 rotates clockwise, and the roll 21 of the kneading roll 19 which abuts against the ink roll 17 rotates counter-clockwise.
Thus, the printing impression roll 38 performs the second printing onto the strip^∼shaped article subjected to printing S1, which returns to the right end of the duplicator main body 22, and as shown in Fig. 2, the application roller 39 performs rotational movement downward together with the support arm 40 to abut against the printing impression roll 38. During this period, the strip-shaped article subjected to printing S1 is supplied by a certain length and stops.
Then, the printing impression roll 38 starts proceeding again from the right end of the duplicator main body 22 toward the central direction, and goes on to the third printing in accordance with the same cooperative relationship as that of the first printing.
The above-mentioned movement in which the application rollers 39 and 41 abut against the printing impression roll 38 to thereafter perform the rotational movement to abut against the ink rolls 16 and 17 and further to perform the rotational movement from the abutment against the ink rolls 16 and 17 toward the abutment against the printing impression roll 38 is conducted, for example, by means of suitable cooperation with cam mechanisms 43 and 44 shown in Fig. 2.
On the other hand, as described above, the above-mentioned printing impression roll 38 is attached to th e duplicator main body 22 in a manner capable of forward or backward movement, which is supported by the shaft in a rotatable manner.
A gear 53 is fixed to one end of a rotation shaft 52 of the printing impression roll 38, and at a downward position of this gear 53 is arranged a rack mechanism 54 in parallel with the forward or backward movement direction of the printing impression roll 38, and the construction is such that the rack mechanism 54 is allowed to engage with the gear 53, thereby the printing impression roll 38 is allowed to perform positive or reversed rotation while performing forward or backward movement. The forward or backward movement of the printing impression roll 38 is conducted by means of a driving belt arranged at one end or both ends of the rotation shaft 52.
At one end of the rotation shaft 52 of the above-mentioned printing impression roll 38 thus formed is arranged a preceding positive or reversed rotation mechanism 57.
The preceding positive or reversed rotation mechanism 57 thus formed has such a structure that the positive or reversed rotation in ac accordance with the forward or backward movement of the above-mentioned printing impression roll 38 is allowed to rotate faster than the standard positive or reversed rotation in which the engagement between the above-mentioned gear 53 and the rack mechanism 54 is regarded as the engagement between a standard gear and a standard rack engaging therewith. Concretely, as shown in Fig. 6, it comprises a gear 58 which is fixed to one end of the rotation shaft 52 of the printing impression roll 38 and a rack 59 which is arranged at a downward position of the gear 58 in parallel with the forward or backward movement direction of the printing impression roll 38. This rack 59 is set to give rotation faster than the standard positive or reversed rotation in which the engagement between the above-mentioned gear 53 and the rack mechanism 54 is regarded as the engagement between the standard gear and the standard rack engaging therewith.
At this time, the preceding positive or reversed rotation mechanism 57 may be added with a slip driven rotation body. With respect to this slip driven rotation body, when forced positive or reversed rotational force is applied to the printing impression roll 38 to provide rotation faster than the standard positive or reversed rotation, the forced positive or reversed rotation is subjected to slip to simulate the rotation in accordance with the engagement between the above-mentioned gear 53 and the rack mechanism 54 to some extent so as to allow the printing impression roll 38 to rotate. Concretely, for example, it comprises a disk which is fixed to the rotation shaft 52 by means of a pin or the like, a gear which outwardly fits to the rotation shaft 52 in a freely rotatable manner and has fewer teeth than those of the above-mentioned gear 53, a pressurizing disk which outwardly fits to the rotation shaft 52 in a manner capable of free sliding and is arranged at a position to interpose the gear with the disk, and a spring which is arranged between a spring base plate fixed to the rotation shaft 52 and the pressurising disk and pressurizes the pressurizing disk toward the direction of the gear (not shown).
On the other hand, with respect to the above^∼mentioned rack mechanism 54, a first rack 60 and a second rack 61 arranged in parallel are allowed to approach or contact, and the above-mentioned gear 53 engages with the first rack 60 and the second rack 61 at the same time. The teeth of the first rack 60 and the second rack 61 are formed such that the backlash becomes large when the gear 53 is engaged; that is, the tooth groove of the rack is made to have a groove width which is wider than the regular one to provide looseness.
As shown in Fig. 7, the rack 59 which constitutes the preceding positive or reversed rotation mechanism 57 is fixed to a frame 62 through a side plate 69. The first rack 60 which constitutes the rack mechanism 54 is installed on a base body 68 for the rack in a manner capable of sliding. In addition, the second rack 61 which constitutes the rack mechanism 54 is fixed on the base body 68 for the rack. A base stand 63 for placing the strip-shaped article subjected to printing S1 is fixed in the duplicator by means of a constitution other than the frame 62.
The movement adjustment of the first rack 60 which constitutes the above-mentioned rack mechanism 54 is performed, for example, as shown in Fig. 6, such that a screw rod 64 is allowed to abut against one end face of the first rack 60 so as to screw this screw rod 64. The screw rod 64 is attached at a predetermined position through a joint piece 65 having substantially an L-shape. Therefore, when the screw rod 64 is rotated, the first rack 60 on the base body 68 for the rack moves to deviate phases of teeth of the first rack 60 and the second rack 61. In this case, when a dial knob 66 is attached to one end or the other end of the screw rod 64, visual observation of the movement adjustment becomes possible, which is extremely convenient. When the movement adjustment is completed, a handle 67 for the rack is rotated to fix the position of the first rack 60.
Furthermore, with respect to the first rack 60 and the second rack 61 which constitute the rack mechanism 54, the entire movement adjustment is possible. As described above, the first rack 60 and the second rack 61 are fixed to the base body 68 for the rack. Therefore, for example, as shown in Fig. 6, the movement adjustment thereof is performed such that a screw rod 70 is allowed to abut against one end face of the base body 68 for the rack, and the screw rod 70 is screwed. The screw rod 70 is attached to a side wall 71 with screwing engagement. Therefore, when the screw rod 70 is rotated, the first rack 60 and the second rack 61 move together with the base body 68 for the rack. In this case, when a dial knob 72 is attached to one end or the other end of the screw rod 70, visual observation of the movement adjustment becomes possible, which is extremely convenient. When the movement adjustment is completed, a handle 73 for the base body for the rack is rotated to fix the position of the base body 68 for the rack.
Next, the operation thereof will be explained in the following.
That is, at first, assuming that the strip-shaped article subjected printing S1 does not deviate when the strip-shaped article subjected to printing S1 contacts with the printing impression 56, the positional relationship between the gear 53 of the printing impression roll 38 and the rack mechanism 54 so as to perform printing at a regular position. While maintaining the second rack 61 in the rack mechanism 54 fixed, the screw rod 64 is rotated to move the first rack 60 so as to deviate the phase of the teeth of the first rack 60 and the second rack 61. At this time, since the tooth grooves of the first rack 60 and the second rack 61 have been formed to have a groove width wider than the tooth groove of the standard rack to give looseness, the phase of teeth of the first rack 60 and the second rack 61 deviates, and thereby the tooth groove becomes narrow to approach the width of the tooth groove of the standard rack.
At a position to approach the tooth groove of the standard rack to some extent, the first rack 60 is fixed, and the printing impression roll 38 is allowed to perform forward or backward movement.
At this time, since the preceding positive or reversed rotation mechanism 57 is arranged at one end of the rotation shaft 52, with respect to the gear 53, the engagement between the gear 53 and the rack mechanism 54 always provides preceding rotation of a degree of the looseness, and for example, as shown in Fig. 8, when the printing impression roll 38 moves from the left to the right, as shown in Fig. 9, the teeth of the gear 53 abut against the left side in the rack mechanism 54, that is, the rearward side with respect to the movement direction of the gear 53 so as to engage with the rack mechanism 54. Therefore, the rotation of the printing impression roll 38 always maintains a preceding state with respect to the standard rotation of the printing impression roll 38 rotating in accordance with the forward or backward movement with engagement between the rack having the regular groove width and the gear.
By doing so, the degree of deviation of the strip-shaped article subjected to printing S1 in the forward direction of the movement of the printing impression roll 38 during the contact between the strip-shaped article subjected to printing S1 and the printing impression 56 of the printing impression roll 38 is offset by performing preceding rotation beforehand with respect to the standard rotation of the printing impression roll 38.
As a result, when printing is performed while rotating the printing impression roll 38 in accordance with the forward or backward movement, as shown in Fig. 8, in the case of the movement in the forward direction from the left to the right, in a stage of migration from a step shown in (A) in which the printing impression 56 has not yet contacted the strip-shaped article subjected to printing S1 to a step shown in (B) in which the printing impression 56 contacts the strip-shaped article subjected to printing S1, the printing impression 56 movingly deviates from the regular position in the movement direction of the printing impression roll 38, so that the gear 53 is allowed to perform the preceding rotation to that extent as described above in the relationship between the gear 53 and the preceding positive or reversed rotation mechanism 57, thereby the contact is performed with the strip-shaped article subjected to printing S1 faster than an expected movement position of the printing impression roll 38 to cause deviation, and when the expected regular printing position of the printing impression roll 38 contacts with the strip-shaped article subjected to printing S1, the strip-shaped article subjected to printing S1 has already preceded to give deviation, so that the degree of deviation is offset, and in a step shown in (C), the printing can be performed onto the regular position of the strip-shaped article subjected to printing S1.
On the other hand, the deviation of the strip-shaped, article subjected to printing S1, which occurs due to frictional resistance during the forward or backward movement of the printing impression roll 38 while contacting the strip-shaped article subjected to printing S1 after the contact of the printing impression roll 38 with the strip-shaped article subjected to printing S1, the fact that the strip-shaped article subjected to printing S1 is not accurately supplied and arranged at a specified place on the base stand 63 and the like, is offset by moving the rack mechanism 54 in the forward or backward movement direction of the printing impression roll 38. That is, when the screw rod 70 is rotated to move the rack mechanism 54 in the forward or backward movement direction of the printing impression roll 38, the printing impression roll 38 also rotates in accordance with the moving action thereof, so that the contact face between the strip-shaped article subjected to printing S1 and the printing impression 56 of the printing impression roll 38 is adjusted using the rotation of the printing impression roll 38 in accordance with the movement of the rack mechanism 54.
When a pattern or letters is continuously and suitably printed onto the strip^∼shaped article subjected to printing S1 by means of the duplicator 3 as described above so as to form a print portion 82, the detection of a printing state and a printing position is performed, and the correction thereof is performed, if necessary.
Next, with respect to the printing device 1, the construction is such that the strip-shaped article subjected to printing S1 which is an adhesive paper or the like having an adhesive layer at the back face of a substrate such as paper, a film or the like being constituted by protecting its lower face with peeling paper having a peeling treatment face, is sent from the paper supply device 2, the label printing of a pattern or letters is performed by the intermittent duplicator 3 having the above-mentioned reciprocating printing impression to form the strip-shaped printed article S2, and then laminating processing is optionally applied to the surface of the printed strip-shaped printed article S2 by means of the laminating device 4, and then labels as the product are continuously punched by means of the die cutting device 5.
In the downstream step of the die cutting device 5 is added and provided the punched residue winding device 6 having a reeling device 132 for reeling the continuous punched residue A after punching labels from the strip-shaped printed article S2. The product after the removal of the punched residue A is wound by the product winding device 8, or individually cut just before this device 8.
As shown in Fig. 10, this punched residue winding device 6 is formed such that the punched residue A continuously sent from the die cutting device 5 through a sending roller 133 is allowed to pass through a guide roller 134 to be wound by the reeling device 132 arranged at an upward position.
This reeling device 132 is constituted by a reeling roller 135 which is driven to rotate by a driving device such as a motor or the like (not shown), and a reeling auxiliary roller 137 is arranged substantially parallel closely adjacent to the reeling roller 135, the reeling roller 135 has a construction so as be to pressurize in the direction to abut against the reeling auxiliary roller 137 using its own weight or suitable urging force, which is driven and rotated at a faster rotation speed by a predetermined ratio as compared with a printing speed of the above-mentioned intermittent duplicator 3, so as to make it possible to always apply tension to the strip-shaped printed article S2.
The formation is made such that the punched residue A in a state of the formation of the reeling device 132 as described above is allowed to pass between the reeling roller 135 and the reeling auxiliary roller 137 to be wound by the reeling roller 135.
In addition, the construction is such that the continuous punched residue A to be wound by the reeling roller 135 is wound in such a way that provided that its one face is an adhesive adhering face Al, the adhesive adhering face Al contacts the peripheral surface of the reeling roller 135.
This provides the so-called surface winding in which the adhesive adhering face Al of the continuous punched residue A is wound with adhesion around the peripheral surface of the reeling roller 135, which is extremely convenient for handling.
Between the guide roller 134 and the reeling device 132 thus arranged is provided a residue cut detecting bar 136 arranged to give tension so that the above-mentioned punched residue A is not cut by means of its own weight.
Its concrete structure is such^∼that one end of the rotatable residue cut detecting bar 136 is supported in a manner capable of free tilting in upper and lower directions, and the residue cut detecting bar 136 is arranged to apply tension by its own weight downward to the strip-shaped punched residue A passing between the guide roller 134 and the reeling device 132.
By doing so, when the punched residue A is cut, the repulsive resistance from the punched residue A disappears in a state of giving tension to the punched residue A by the residue cut detecting bar 136, so that the whole apparatus including the above-mentioned die cutting device 5 and the reeling device 132 stops, so as to prevent the winding deficiency which may occur when the punched residue is cut and the treatment deficiency which may provide a disordered state of the punched residue. In this case, when the winding speed of the residue is faster than the sending speed from the die cutting device 5, the residue cut detecting bar 136 is lifted upwardly, and when the residue cut detecting bar 136 is lifted to a position above a certain position, the reeling device 132 is stopped, or when the residue cut detecting bar 136 is lowered to a position below a certain position, the reeling device 132 is operated again.
In this case, although not shown in the figures, the residue cut detecting bar 136 may be formed to apply tension to the punched residue A by urging force provided by a spring or the like instead of its own weight, and the abovementioned guide roller 134 itself may be formed to be capable of driving rotation.
Of course, the present invention is not limited to the above-mentioned example.
The present invention constituted as described above lies primarily in the printing device comprising the duplicator 3 for performing intermittent printing onto the strip-shaped article subjected to printing S1 supplied from the paper supply device 2 using the printing impression roll 38 which performs positive or reversed rotation while performing forward or backward movement in the direction perpendicular to the sending direction of the strip-shaped article subjected to printing S1, the die cutting device 5 for punching the strip-shaped printed article S2 printed by the duplicator 3 into a suitable shape, and the punched residue winding device 6 for winding the punched residue A after punching by the die cutting device 5, wherein the duplicator 3 is provided with the ink applying device 11 which allows the application roller 39 for applying ink during the forward step onto the printing impression face of the printing impression roll 38 which performs positive, or reversed rotation while performing forward or backward movement and the application roller 41 for applying ink during the backward step to contact with each of individual ink rolls 16 and 17 which rotate in the reversed direction with respect to the rotation direction of each of the application rollers 39 and 41 so as to adhere ink onto each of the application rollers 39 and 41, which comprises the bottling roll 13 for sending ink from the ink tank 12, the access roll 15 which performs rotational movement with the support arm 14 so as to suitably abut against the bottling roll 13, and the fixed metal roll 18 and the kneading roll 19 for adhering ink supplied by the bottling roll 13 and the access toll 15 onto the ink rolls 16 and 17, and the kneading roll 19 is rotated at a high speed so as to adhere ink onto the kneading roll 19, the ink rolls 16 and 17 and the fixed metal roll 18 to circulate it, so that the adhesion of ink onto the application rollers 39 and 41 can be made uniform using an extremely small number of the rolls 19, 16, 17, and 18.
That is, the ink is allowed to adhere to and circulate on the kneading roll 19, the ink rolls 16 and 17, and the fixed metal roll 18, and thereby no unevenness is given for the amount of ink to b applied onto the kneading roll 19, the ink rolls 16 and 17, and the fixed metal roll 18, and the adhesion of ink onto the application rollers 39 and 41 can be made uniform.
In addition, only the access roll 15, the fixed metal roll 18, the kneading roll 19, and the ink rolls 16 and 17 are present between the bottling roll 13 for sending ink and the application rollers 39 and 41 for applying ink onto the printing impression roll 38, so that the ink can be smoothly applied onto the printing impression roll 38 in accordance with rotation of each of the rolls 15, 18, 19, 16, and 17.
Furthermore, the number of rolls 15, 18, 19, 16, and 17 is small, so that the scattering of ink adhered to each of the rolls 15, 18, 19, 16, and 17 can be restricted to the minimum. At the same time, the number of each of the rolls 15, 18, 19, 16, and 17 to rotate in abutment is small, so that the heating of each of the rolls 15, 18, 19, 16, and 17 can be restricted, and the duplicator main body 12 can be continuously used for a long time.
On the other hand, when the Constitution is made by fixing the bottling roll 13 for sending ink from the ink tank 12, the access roll 15 which performs rotational movement with the support arm 14 to suitably abut against the bottling roll 13, and the fixed metal roll 18 and the kneading roll 19 for adhering ink supplied by the bottling roll 13 and the access roll 15 onto the ink rolls 16 and 17 to the sliding base stand 24 which is attached in a manner capable of sliding in the horizontal direction via the rail 23, the sliding base stand 24 can be suitably moved to allow the kneading roll 19 to abut against the ink rolls 16 and 17 with ease. In this state, when the kneading roll 19 is rotated at a high speed, the ink adhered to each of the rolls 15, 18, 19, 16 and 17 is adhered and circulated, and no unevenness occurs in the amount of ink to be applied onto the kneading roll 19, the ink rolls 16 and 17, and the fixed metal roll 18.
When inks having different colors are installed on the sliding base stands 24 and 25 beforehand, only by suitably sliding the sliding base stands 24 and 25, the inks having different colors can be applied onto the printing impression roll 38 with ease.
Furthermore, when the ink applying device 11 is constituted such that the ink supply body 26 comprising the ink tank 12 and the bottling roll 13 is installed on the sliding base stand 24 in a detachable manner, it is possible to perform washing of the ink tank 12 and the bottling roll 13 and supplemental supply of ink without interrupting the printing operation, and only by suitably sliding the two sliding base stands 24 and 25, the inks having different colors can be applied onto the printing impression roll 38 with ease.
Therefore, it is unnecessary to exchange a plurality of rolls every time the color of ink is changed, and it is possible to change the color of ink to be applied onto the printing impression roll 38 easily and rapidly.
Alternatively, the duplicator according to the present invention is provided with the ink applying device 11, and this ink applying device 11 comprises the bottling roll 13 for sending ink from the ink tank 12, the access roll 15 which performs rotational movement with the support arm 14 to suitably abut against the bottling roll 13, and the fixed metal roll 18 and the kneading roll 19 for adhering ink supplied by the bottling roll 13 and the access roll 15 onto the ink rolls 16 and 17, and its constitution is extremely simple, so that a large amount of products can be produced in a short time to provide products at a low cost.
In addition, with respect to the duplicator 3, the deviation of the strip-shaped article subjected to printing S1, which occurs due to the friction resistance during the forward or backward movement with the contact of the printing impression roll 38 with the strip-shaped article subjected to printing S1, the fact that the strip-shaped article subjected to printing S1 is not supplied and arranged at a specified place on the base stand 63 and the like, can be adjusted by the simple operation.
That is, the rack mechanism is constituted in a manner capable of movement in the forward or backward directions of the printing impression roll 38, and the printing impression roll 38 also rotates in accordance with the movement action thereof through the gears 53 and 58, so that the contact face between the strip-shaped article subjected to printing S1 and the printing impression 56 of the printing impression roll 38 is adjusted using the rotation of the printing impression roll 38 in accordance with the movement of the rack mechanism 54.
As a result, complicated operation is avoided in which the lock bolt which fixes the printing impression roll 38 and its gear is loosened so as to set the change of phase of the printing impression roll 38 with manual rotation, and the contact position between the strip-shaped article subjected to printing S1 and the printing impression of the printing impression roll 38 can be controlled rapidly.
In addition, in the operation in which the lock bolt is loosened so as to set the change of phase of the printing impression roll 38 with manual rotation, it is difficult to perform fine phase setting, and the phase of the printing impression roll 38 must be set again and again during printing, whereas according to the present invention, anyone can extremely accurately control the contact position between the strip-shaped article subjected to printing S1 and the printing impression 56 of the printing impression roll 38 by means of the simple operation.
Moreover, even during the forward or backward movement of the printing impression roll 38, the rack mechanism can be moved to -control the contact position between the strip-shaped article subjected to printing S1 and the printing impression 56 of the printing impression roll 38, so that the printing operation is never interrupted.
Therefore, by moving the rack mechanism 54 in the forward or backward movement direction of the printing impression roll 38, the deviation of mold punching due to color deviation during printing or printing positional deviation can be prevented.
Therefore, in order to make the printing state of the strip-shaped printed article and the downstream processing state by the downstream step processing device to be regular within an acceptable range, anyone can perform the control extremely easily, rapidly, accurately, and without training.
The punched residue winding device 6, which automatically winds the continuous punched residue A during the period after suitably and continuously punching by means of the above-mentioned die cutting device 5, is constituted by the reeling roller 135 which performs driving and rotation and the reeling auxiliary roller 137 which is arranged in a substantially parallel manner closely adjacent to the reeling roller 135; the reeling roller is formed so as to apply pressure in the direction to abut against the reeling auxiliary roller 137 by its own weight or other suitable urging force, so that when the construction is made such that the above-mentioned continuous punched residue A is allowed to pass between the reeling roller 135 and the reeling auxiliary roller 137 so as to wind around the reeling roller 135, the continuous punched residue A is wound by the reeling roller 135 while being pressed by the reeling auxiliary roller 137, so that it is possible to wind tightly.
In this case the construction is made such that the winding is performed at the winding speed by the reeling roller 135 which is faster than the printing speed of the duplicator 3 by a certain ratio, so that the continuous punched residue A is always wound in a state of tension, is wound tightly, and can be reeled in a regular manner.
With respect to the continuous punched residue A to be wound by the reeling roller 135, provided that its one face is the adhesive adhering face Al, the construction is made to wind allowing the adhesive adhering face Al to contact with the peripheral surface of the reeling roller 135, so that when it is wound tightly and in a regular manner, the so-called surface winding state is obtained, so that there is no winding deficiency due to adhesive effects of the adhesive, no cutting of the residue or the like, which makes handling extremely convenient.
Moreover, the residue cut detecting bar 136 which is arranged to give tension so as to cut the above-mentioned punched residue A by means of its own weight or urging force is provided between the guide roller 134 arranged at the rearward portion from the die cutting device 5 and the above-mentioned reeling device 132 for reeling the punched residue A arranged at the rearward portion from the guide roller 134, and the formation is made such that when the repulsive resistance from the punched residue A disappears in the state of giving tension to the punched residue A by means of the residue cut detecting bar 136, the entire apparatus including the above-mentioned die cutting device 5 and the reeling device 132 is immediately stopped, whereby in the punched residue winding device 6, after the punching of the product with respect to the strip-shaped printed article S2 having the reeling device 132, when the tension which does not cause cutting is given to the above-mentioned punched residue A by the own weight of the residue cut detecting bar 136 or the urging force, then the punched residue A can be securely wound with the reeling device 132 in a regular manner.
In addition, when the punched residue A is cut, the repulsive resistance from the punched residue A disappears in the state of giving the tension to the punched residue A by the residue cut detecting bar 136, so that the whole apparatus, including the above-mentioned die cutting device 5 and the reeling device 132, stops immediately; and it is possible to prevent the winding deficiency generated when the punched residue is cut and the treatment deficiency in which the punched residue becomes disordered.
Therefore, using an extremely simple device, the continuous punched residue generated when the product is suitably and continuously punched from the strip-shaped printed article S2 is tightly wound in a regular manner without being cut, and when the punched residue is cut, the reeling device for reeling the residue and the device in the upstream step thereof are immediately stopped to prevent disorder, and the continuous punched residue can be treated in a regular manner.
Thus, according to this invention, there are provided various excellent effects such that the number of the ink rolls to be interposed between the bottling roll for supplying ink and the application roller for applying ink onto the printing impression roll is reduced; thereby, the ink is rapidly supplied to the printing impression roll, the scattering of ink adhered to each of the rolls and the heating of each of the rolls are restricted to the minimum, the color of ink to be supplied can be easily changed, the error in the printing position which occurs due to the deviation of the printing paper sheet generated during the contact between the impression face of the printing impression roll and the printing paper sheet, the friction resistance during the contact between the printing impression roll and the printing paper sheet to perform the forward or backward movement, the fact that the printing paper sheet is not accurately supplied and arranged at a specified place on the base stand and the like can be adjusted by an extremely-simple operation, and in order to make the printing state of the strip-shaped printed article and the downstream processing state by the downstream step processing device to be regular within an acceptable range, the control can be performed extremely easily, rapidly, and accurately, and furthermore, the continuous punched residue generated when the product is suitably and continuously punched from the strip-shaped printed article is reeled in a regular manner without being cut, and when the punched residue is cut, the reeling device for reeling the residue and the device in the upstream step thereof are immediately stopped to prevent disorder, and the state in which the continuous punched residue can be treated in a regular manner can be ensured and the like.
