Description

  The present invention is a print in which a variable-size cut paper or a continuous printed second print paper is bonded to a first print paper that has been printed continuously while aligning the respective print positions. The present invention relates to a paper laminating apparatus.

  One continuous paper is cut between each printed picture printed on the sheet cutting device to make the positional relationship between the printed pictures on this continuous paper unrelated, and between the printed pictures on the other continuous paper. There is known a technique in which the feeding position of each cut printed picture is adjusted by a feeding conveyor with the interval as a reference so as to match the two (for example, see Patent Document 1).

  In addition, there is also a type in which an unprinted upper sheet is pasted on the upstream side of the printing apparatus on the printed lower sheet, and then the upper sheet is printed so as to match the printing position of the lower sheet. (For example, refer to Patent Document 2).

  All of the conventional techniques described above are bonded together by aligning the printing positions. However, only one cut sheet (Patent Document 1) or only continuous paper (Patent Document 2) can be bonded to one continuous sheet. Because it is limited and the work content that can be processed is specified and lacks versatility, it is necessary to equip each dedicated machine in order to be able to produce a wide variety of products. There was a problem that the equipment cost would increase. In the above-mentioned Patent Document 2, printing is performed on the upper sheet after bonding in accordance with the printing position of the lower sheet, and the printed position of both the upper and lower sheets is accurately aligned. The upper and lower papers printed in advance could not be bonded with high accuracy.

  The present invention has been made in view of the above, and the second printed paper preprinted on the first continuous printed paper preprinted by one apparatus is continuously continuous with the cut paper. It is an object of the present invention to provide a printing paper laminating apparatus that can be selectively aligned in a paper shape and bonded, and has versatility.

  In order to achieve the above object, a printing paper laminating apparatus according to the present invention is preliminarily printed on a first printing paper on a first running line that runs the first continuous printing paper at a predetermined speed.

A second mark set for detecting the detected timing mark A sheet feed control roller that is controlled by the detection values of the first and second mark sensors in each of the first and second travel lines and passes the pattern of each printing paper to the laminating device at the same timing. A cut cylinder provided with a cutter on the outer periphery is provided on the upper side of the receiving cylinder of the laminating apparatus, and the second printing paper wound around the receiving cylinder by the cutter is placed at a predetermined pitch. Can be switched between a cutting operation at a position where the cutter is separated from the receiving cylinder and a state where the second printing paper is not cut, and the second printing paper is cut into the first printing paper by the laminating apparatus. In this configuration, the printed pattern positions are matched and pasted in a continuous paper form.

  In the printing paper laminating apparatus, the cylinder of the laminating apparatus has a vacuum configuration in which a large number of suction holes are provided on the peripheral surface, and the cut cylinder of the laminating apparatus is detachable from the main body frame. Yes.

  According to the present invention, by selectively using the cutting cylinder of the laminating apparatus, the second printing paper pre-printed with respect to the first continuous paper-like printing paper pre-printed is in a continuous paper state. Can be selectively and accurately aligned in either of the cut paper state or the cut paper state, and a single printing paper laminating device can produce a wide variety of product types, making it possible to produce a wide variety of products. It becomes possible.

  In addition, an increase in the amount of work that can be processed by a single device makes it possible to reduce equipment costs and reduce product costs.

  Furthermore, since the work function is improved as described above, it is possible to work on the contents of a plurality of devices with a single device, so that it is possible to reduce the installation space of the device at the work site.

  FIG. 1 schematically shows a printing paper laminating apparatus. In FIG. 1, reference numeral 1 denotes a first paper feeding unit that feeds a first continuous paper-like printing paper 2 to a first traveling line A. The winding unit 4 is located on the most downstream side of the first traveling line A and winds up the first printing paper 2. The winding unit 4 is located on the upper side of the first traveling line A and is a second continuous paper. This is a second paper feed unit that supplies the printing paper 5 to the second travel line B. The second traveling line B is configured such that the printing paper 5 travels toward the upstream side of the first traveling line A.

  The first printing paper 2 has a predetermined pattern printed on the surface at a predetermined pitch and a timing mark printed for each pattern. Further, the second printed paper 5 is printed with the same pattern as the pattern of the first printed paper 2 on the surface of the first printed paper 2 and the pasted pattern to be pasted on the surface of the first printed paper 2. Timing marks are printed for each pasted pattern.

  Reference numeral 6 denotes a first paper which is arranged immediately downstream of the first paper feeding unit 1 and feeds the first printing paper 2 supported by the first paper feeding unit 1 to the first travel line A at a predetermined speed. One feeding control roller 7 is a pulling roller comprising a pair of rollers that are arranged downstream of the first travel line A and pull the first printing paper 2 on the travel line A at a predetermined speed. . In this embodiment, the pulling roller 7 has a function of a reference conveying roller, and the pulling roller 7 rotates at a constant rotational speed. The speed of the first paper feed control roller 6 is controlled with respect to the rotation of the pulling roller 7.

  8, in the second traveling line B, the second printing paper 5 from the second paper feeding unit 4 is moved in a direction opposite to the traveling direction (upstream direction) of the first printing paper 2 at a predetermined speed. It is the 2nd paper feed control roller which consists of a pair of roller to supply.

  Timing marks printed for the respective patterns of the first printing paper 2 and the second printing paper 5 immediately downstream of the first paper feeding control roller 6 and the second paper feeding control roller 8, respectively. First and second mark sensors 9 and 10 for detecting the above are provided.

  11 is a gluing device for gluing the surface of the first printing paper 2 fed by the first paper feed control roller 6 with a predetermined pattern; 12 is a gluing device 11 for the first travel line A; The laminating device is disposed on the downstream side of each of the second paper feed control rollers 8 on the second travel line B.

  The second paper feed control roller 8 in the second travel line B is basically rotated at the same travel rotational speed as the pulling roller 7 serving as a reference transport roller, but is detected by the second mark sensor 10. The rotational speed is controlled via the control device according to the value.

  That is, the detection value of the first mark sensor 9 and the detection value of the second mark sensor 10 are compared by a control device (not shown), and if there is a difference between the detection values of the mark sensors 9 and 10, The second sheet feeding control roller 8 is controlled by the control device so that this difference becomes zero.

  FIG. 2 schematically shows the bonding apparatus 12 in an enlarged manner, wherein 13 is a receiving cylinder, 14 is an impression cylinder that is slidably contacted from below, and the receiving cylinder 13 is connected to the impression cylinder 14. The rolling contact portion is rotated so as to face the traveling direction of the first printing paper 2 passing therethrough. The receiving cylinder 13 has a vacuum structure and is not particularly shown, but is hollow and has a large number of pores communicating with the hollow portion on the peripheral surface. The hollow portion is evacuated by a vacuum device. By doing so, the vacuum function acts on the peripheral surface of the receiving cylinder 13. The receiving cylinder 13 is rotated slightly faster than the peripheral speed of the first paper feed control roller 6 by a drive mechanism (not shown). Then, the second printing paper 5 fed from the second paper feed control roller 8 is wound from the upper side of the receiving cylinder 13 via the guide roller 15 and is reversed by the rotation of the receiving cylinder 13 to be the first It is superimposed on the upper side of the printing paper 2 and travels along the first travel line A in the same direction as the first printing paper 2.

  Reference numeral 16 denotes a cut cylinder provided on the upper side of the receiving cylinder 13 so as to be able to contact and separate. The cut cylinder 16 is supported by a frame 17 which is detachable from a main body frame 17 supporting the receiving cylinder 13. In a state where the frame 17 is fixed to the main body frame 18, a cutter 19 provided on the cutting cylinder 16 comes into contact with the receiving cylinder 13 to cut the second printing paper 5 along the receiving cylinder 13. The cut drum 16 is driven by a drive motor (not shown) such as a sectional motor that can independently change the rotation speed.

  The first and second paper feed control rollers 6 and 8, the pulling roller 7, the rollers of the gluing device 11, and the receiving cylinder 13 in the above configuration are respectively connected to the main drive device of the printing paper laminating device via a differential device. They are connected so that their rotation speed can be adjusted.

  The drive motor that drives the cut cylinder 16 is driven and controlled based on the detection signal of the second mark sensor 10 that detects the timing mark of the second printing paper 5 in this drive state. Yes.

  In the above configuration, a case where the second printing paper 5 is bonded to the first printing paper 2 in a continuous paper state will be described. In this case, the rotational phase of the cut cylinder 16 is fixed so that the cutter 19 is detached from the receiving cylinder 13. Alternatively, the cut cylinder 16 is removed from the main body frame 18 together with the frame 17 that supports the cut cylinder 16.

  In this state, the first printing paper 2 supported by the first paper feed unit 1 is fed to the travel line by the first paper feed control roller 6 and the pulling roller 7. At this time, the pulling roller 7 rotates at a constant rotation speed, and the first printing on the first travel line A is performed by controlling the first paper feed control roller 6 with respect to the pulling roller 7. The paper 2 travels at a constant speed under an appropriate tension, and is then taken up by the take-up unit 3.

  While the first printing paper 2 on the first traveling line A travels at a constant speed, a timing mark printed on each pattern printed at a constant pitch is first. It is detected by the mark sensor 9 and then pasted by a pasting device 11 to a necessary place for each of the pictures.

  On the other hand, the second printing paper 5 supported by the second paper feeding unit 4 is fed to the second travel line B by the second paper feeding control roller 8 and passes through the laminating device 12 to the first. Is attached to the upper side of the printing paper 2 and travels to the first travel line A by the pulling roller 7 together with the first printing paper 2. At this time, the second mark sensor 10 detects the timing mark printed on the second printing paper 5 together with the pattern.

  At this time, the pattern and timing marks printed on the second printing paper 5 are printed at the same pitch as that of the first printing paper 2, and this pattern is pasted on the second printing paper 5. In the aligning device 12, the paper is passed through the second paper feed control roller 8 so as to travel at the same position as the pattern of the first printing paper 2 at the same timing.

  As a result, the first printing paper 2 and the second printing paper 5 are pasted together by the laminating apparatus 12 in a state in which the pitches of the respective patterns are matched, and are, for example, stacked on the winding unit 13 as a continuous label. Rolled up into a roll.

  At this time, as described above, the pattern and timing marks printed on the second printing paper 5 are printed at the same pitch as that of the first printing paper 2, but when printing both printing papers 2, 5. There are cases where there is a shift in the vertical direction of each pattern (timing mark) due to the different conditions.

  For this reason, the control device (not shown) compares the detection values of the first mark sensor 9 and the second mark sensor 10, and if there is a difference between the detection values of the two sensors 9, 10, the second supply is performed. The rotational speed of the paper control roller 8 is controlled with respect to the pulling roller 8, and alignment is performed so that the detection values of both mark sensors 9, 10 are the same.

  As a result, the first and second printing papers 2 and 5 are bonded together in a state in which the respective patterns are registered in the vertical direction, and are wound by the winding unit 3.

  Next, a case will be described in which each pattern of the second printing paper 5 is bonded to each pattern position of the first printing paper 2 while being cut to a predetermined size.

  In this case, the cutting cylinder 16 in the laminating apparatus 12 is rotated in accordance with the travel of the second printing paper 5 in a state where the second printing paper 5 is continuously laminated to the first printing paper 2. It is driven and cut into a predetermined size for each pattern of the second printing paper 5, sucked by the receiving cylinder 13, transferred, and pasted on the first printing paper 2.

  The rotation of the cut cylinder 16 at this time is detected at the timing that matches the detection timing when the timing mark printed on the second printing paper 5 is detected by the second mark sensor 10. And the timing (registration) of the pattern of the cut paper and the first printing paper 2 by the second printing paper 5 is detected by the first and second mark sensors 9 and 10 in the same manner as in the case of continuous pasting. The second sheet feeding control roller 8 is controlled so that there is no deviation.

It is a front view which shows roughly the printing paper bonding apparatus which concerns on this invention. It is a configuration explanatory view schematically showing a main part of the present invention.
