[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a label manufacturing apparatus provided with a mechanism for winding a scrap in label manufacturing.
[0002]
[Prior art]
In recent years, in label manufacturing, a label continuous body in which a predetermined number of labels each having a die-cut line formed thereon is adhered to a peeling body, and an unnecessarily referred to as a swarf by leaving only the label on the peeling body. Winding the part is performed. It is desired that such a scrap be taken up in one step of label production be continuously performed.
[0003]
Therefore, FIG. 6 is an explanatory view of winding a scrap in a conventional label production. FIG. 6A is a schematic perspective view, and FIG. 6B is an explanatory view of separation of scraps from a continuous label body. In FIGS. 6A and 6B, a label continuous body 101 is formed such that a label base 103 is releasably adhered to a release body 102 having a release agent formed on a predetermined base (for example, paper) with an adhesive. The label base 103 is in a state where predetermined information is printed or printed on an area where a predetermined number of labels are to be formed, and a cutout line is formed in the area, so that the label 104 can be separated from the label 104 and the scrap 105. It is said.
[0004]
Such a label continuous body 101 is sequentially conveyed, and the scrap 105 is separated at the guide roller 106. The separated scrap 105 is sequentially wound on a winding shaft 107 and wound on a paper tube 108 fixed at the time of winding. Then, the scrap 105 is separated, and the peeled body 102 in a state where only the label 104 remains is wound up, for example.
[0005]
[Problems to be solved by the invention]
However, since the take-up scrap take-up mechanism in the above-mentioned conventional label manufacturing apparatus is designed to take up only at one point, if the take-up roll becomes large and must be removed in one process, the apparatus is temporarily stopped. It must be stopped and removed, a new paper tube 108 must be set on the take-up roller 107 and re-started, which causes a problem that the production efficiency is reduced.
[0006]
The present invention has been made in view of the above problems, and has as its object to provide a label manufacturing apparatus that continuously winds up scraps in label manufacturing to improve manufacturing efficiency.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, according to the invention of claim 1, a label continuum in which a predetermined number of labels are die-cut on a label substrate that is releasably adhered to a release body, the label of the label substrate is removed. A label manufacturing apparatus including a winding unit that winds an unnecessary body other than the above, wherein the winding unit includes a rotation support unit in which at least two winding shafts are arranged at predetermined intervals, and the one winding shaft includes: Reversing drive means for winding the unnecessary body at a winding position, rotating the rotation support means to position the other winding shaft at the winding position when a predetermined winding amount is reached, and Cutting means for cutting the unnecessary body wound by the one winding shaft when the winding shaft is located at the winding position.
[0008]
According to the second aspect of the invention, the rotation of the winding shaft is controlled in accordance with a winding amount of the unnecessary body, and the cutting unit is switched to the other winding shaft at the winding position. In this case, the unnecessary body is cut by controlling the rotation speed of the winding shaft after the winding is completed.
[0009]
As described above, at least two winding shafts arranged at a predetermined interval are used in the rotation supporting means, and when the winding of the unnecessary body by the winding shaft reaches a predetermined amount, the reversing drive means rotates the rotation. The supporting means is rotated to position the other winding shaft at the winding position, and the unnecessary body wound by the cutting means is cut. That is, the unnecessary body is sequentially wound by the two winding shafts, and the unnecessary body roll that has been wound and cut is removed, thereby eliminating the need to stop the apparatus when removing the unnecessary body winding roll. In addition, it is possible to save time by stopping the apparatus, and to prevent unnecessary load from being applied to the label continuity 21 because the apparatus is not decelerated or accelerated when the apparatus is stopped or restarted. This makes it possible to improve the manufacturing efficiency of the label manufacturing apparatus by continuously winding the unnecessary body.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration diagram of a scrap removal winding means in a label manufacturing apparatus according to the present invention. 1 (A) and 1 (B), a scrap removal winding means 11 is configured such that a rotation support plate 12 as a rotation support means is rotatable by a rotation shaft 13 and is wound around both ends of the rotation support plate 12 at predetermined intervals. The take shafts 14 and 15 are provided rotatably. Then, paper tubes 16 and 17 are fitted to the respective winding shafts 14 and 15. The rotating shaft 13 constitutes a part of the inversion driving means.
[0011]
The winding shafts 14 and 15 include various known types such as a cone fastening system, an air shaft system, and a center cone system. Here, the air shaft system will be described as an example. That is, the paper tubes 16 and 17 are fitted to the winding shafts 14 and 15, and air is injected into the winding shafts 14 and 15 to protrude the expansion pieces to fix the paper tubes 16 and 17. By discharging the air, the expansion pieces are retracted so that the paper tubes 16 and 17 can be freely inserted and removed.
[0012]
On the other hand, as described above (FIG. 6B), the label continuum 21 is formed such that the label base 23 can be peeled off by an adhesive on a release body 22 having a release agent formed on a predetermined base (for example, paper). The label base 23 is adhered, and predetermined information is printed or printed on a region where a predetermined number of labels are formed, and a stamp line is formed in the region, so that the label 24 portion and the unnecessary body (cut waste 25 ) Part is in a separable state. That is, after the above-described label continuous body 21 has been die-cut as described below, unnecessary bodies of the label base 23 are separated as the scraps 25 at the guide roller 31 and the scraps 25 are removed by the scrap-winding means. It is wound up at 11.
[0013]
Here, FIG. 2 shows a conceptual diagram of a label manufacturing apparatus provided with the scrap rewinding means of FIG. In FIG. 2, the label manufacturing apparatus 41 is a device in which the label continuous body 21 before die-cutting is supplied in the form of a roll, and the conveyed label continuous body 21 is provided with a die-cut cylinder 43 via a guide roller 42. It is conveyed in the direction of the guide roller 31. The die-cutting cylinder 43 is formed by forming a die-forming groove (or hole) having a predetermined size on the surface of the rotating body, and forms a die-cutting line in a region on the label base 23 that becomes a label by rotation.
[0014]
At the guide roller 31, an unnecessary body (cut waste 25) is separated from the label continuous body 21 and wound by the scrap waste winding unit 11. Are wound up in a roll shape via a guide roller 44 in a state where they are peelably adhered.
[0015]
The die-cutting cylinder 43 is driven by a die-cutting drive unit 51. The die-cutting drive unit 51 drives the die-cutting cylinder 43 to rotate in synchronization with the transport speed of the label continuous body 21. The winding shafts 14, 15 in the above-mentioned scrap removing winding means 11 are driven by a winding shaft driving section 52, and the winding shaft driving section 52 is controlled to rotate by a driving control means described later (FIG. 3). The winding shafts 14 and 15 are individually driven and controlled by the signal. The rotation shaft 13 and the inversion drive section 53 constitute an inversion drive means. Further, the winding shaft drive section 52 also supplies air to the winding shafts 14 and 15 and drives exhaust.
[0016]
The rotating shaft 13 in the above-mentioned scrap rewinding means 11 is driven by a reversing drive unit 53, and the reversal drive unit 53 has reached a predetermined amount of the remnants 25 being wound by the winding shafts 14 and 15. At this time, the rotation support plate 12 is rotated, for example, by 180 degrees. The supply of the label continuous body 21 from the roll shape is performed by the supply driving unit 54, and the roll continuous winding of the label continuous body 21 from which the scraps 25 are separated is performed by the winding drive unit 55. In this case, the supply speed (transport speed) of the supply drive unit 54 and the winding speed of the winding drive unit 55 are controlled so as to be synchronized.
[0017]
FIG. 3 shows a block diagram of the drive control means of the label manufacturing apparatus of FIG. In FIG. 3, the drive control means 61 includes a control means 62, a bus 63, an interface (IF) 64, first and second winding shaft drive control means 65 and 66, an inversion drive control means 67, and a stamping drive as appropriate. Control means 68, supply drive control means 69 and winding drive control means 70 are provided. The control means 62 controls the overall operation of the label manufacturing apparatus 41 as a whole, and stores a program therefor. Further, the IF 64 is a drive control signal generated in the drive control unit 61 for the above-described die cutting drive unit 51, take-up shaft drive unit 52, inversion drive unit 53, supply drive unit 54, and take-up drive unit 55. Is sent.
[0018]
The first and second winding shaft drive control means 65 and 66 generate a rotation drive control signal for winding the scrap 25 by the winding shafts 14 and 15 and generate the rotation drive control signal inside the winding shafts 14 and 15. To generate air and air exhaust control signals. The rotation drive control signal is a control signal for reducing the number of rotations by, for example, torque control in accordance with the transport speed of the scrap 25 wound by the winding shafts 14 and 15.
[0019]
Further, when the winding of one of the winding shafts 14 and 15 is completed and the winding of the other is started, the rotation of the winding shaft 14 or 15 whose winding has been completed is increased to reduce the rotation speed. By applying a tension generated by the difference, the scrap 25 is cut. The rotation control for cutting the scrap 25 forms cutting means. In addition, instead of controlling the rotation speed of the winding shafts 14 and 15 as described above, a cutting blade may be separately provided.
[0020]
The inversion drive control means 67 sends a rotation drive control signal to the inversion drive unit 53 that rotates the rotating shaft 13 when the scrap 25 wound by the winding shaft 14 (15) reaches a predetermined amount. Generate and send. By the way, although it is not shown whether or not the scrap 25 wound by the winding shaft 14 (15) has reached a predetermined amount, for example, a means for detecting the winding amount is provided on the rotation support plate 12. Alternatively, since the winding speed is known in advance, the time from the start of winding may be set, and the rotation drive control signal may be sent to the inversion drive unit 53 at each time. The stamping drive control means 68 generates and sends a rotation drive control signal synchronized with the transport speed of the label continuous body 21 to the stamping drive unit 51 which rotates the stamping cylinder 43.
[0021]
The supply drive control means 69 generates a rotation drive control signal for supplying the label continuous body 21 at a predetermined supply speed (conveyance speed) from the roll-like state and sends it to the supply drive unit 54. Is made constant, for example, by torque control according to the supply amount. The winding drive control means 70 generates a rotation drive control signal for winding the label continuous body 21 (the peeled body 22 and each label 24) from which the conveyed scrap 25 has been separated into a roll. The feeding speed is sent to the winding drive unit 55, and the speed is reduced by, for example, torque control in accordance with the winding amount because the transport speed needs to be kept constant in order to prevent loosening.
[0022]
Therefore, FIGS. 4 and 5 are explanatory diagrams of the scrap-wound winding operation by the scrap-wound winding means in FIG. In FIG. 4 (A), first, in the scrap removal winding means 11, paper tubes 16 and 17 are fitted to the winding shafts 14 and 15, respectively. The paper tubes 16 and 17 (at least one of the winding shafts 14 and 15 for winding) may be fixed. Here, as shown in FIG. 1A, the scrap 25 is wound around the paper tube 16 fitted to the winding shaft 14.
[0023]
When the first winding shaft drive control unit 65 generates a rotation drive control signal for rotating the winding shaft 14 and sends it to the winding shaft drive unit 52, as shown in FIG. The scrap 25 is wound up by the winding shaft 14 (paper tube 16) positioned at the winding position. At this time, the winding shaft 14 (paper tube 16) is, for example, torqued according to the winding amount. The rotation is controlled in the deceleration direction by the rotation drive control signal by the control.
[0024]
When it is determined from the detection means (not shown) or the time from the start of winding that the winding amount of the scrap 25 by the winding shaft 14 (paper tube 16) has reached a predetermined size, it is shown in FIG. As described above, the inversion drive control means 67 sends a rotation drive control signal for rotating the rotary shaft 13 clockwise by 180 degrees to the inversion drive unit 53.
[0025]
When the rotation support plate 12 is rotated by the rotation of the rotating shaft 13, the winding shaft 15 (the paper tube 17) is positioned at the winding position, and the winding shaft 14 that has performed the winding described above is rotated by the winding shaft 15. It is assumed that there was a position. At this time, since the adhesive is applied to the back surface of the scrap 25, the adhesive becomes the adhesive state with the paper tube 17 by the adhesive.
[0026]
Therefore, as shown in FIG. 5A, the first winding shaft drive control means 65 generates a rotation drive control signal so as to increase the rotation speed of the winding shaft 14 and rotates the winding shaft 14. Let it. As a result, a large tension is applied to the scrap 25 located between the rotary shaft 15 and the rotary shaft 14 and the cut waste 25 is cut.
[0027]
Subsequently, the first winding shaft drive control unit 65 generates a stop signal for stopping the rotation of the rotary shaft 14 and a stop signal for stopping the air supply to the rotary shaft 14, and sends the signal to the winding shaft drive unit 52. Send out. Further, the second winding shaft drive control means 66 generates a rotation drive control signal to rotate the winding shaft 15 and sends it to the winding shaft drive unit 52.
[0028]
Then, as shown in FIG. 5 (B), when the roll-shaped scrap 25 taken up from the rotating shaft 14 is removed for each paper tube 16 and a new paper tube 16 is fitted to the rotating shaft 14. The first winding shaft drive control means 65 generates an air supply signal for supplying air into the winding shaft 14 and sends it to the winding shaft driving section 52 to fix the paper tube 16. The operations shown in FIGS. 4B to 5B are repeated until the supplied label continuum 21 disappears.
[0029]
As described above, it is not necessary to stop the apparatus when removing the scrap 25 wound up in a roll form from the rotary shafts 14 and 15, so that it is possible to save time due to stopping the apparatus and to stop and stop the apparatus. Since deceleration and acceleration are not performed upon restart, it is possible to prevent unnecessary load from being applied to the label continuous body 21 and to wind the scrap 25 at a constant speed, thereby improving the manufacturing efficiency of the label manufacturing apparatus. Can be achieved.
[0030]
The shape of the rotary support 12 is not limited to the shape shown in the embodiment, but may be a desired shape within an appropriate design range. In addition, the function and effect of the present invention can be obtained if at least two rotary shafts are provided on the rotary support body 12. However, three or more rotary shafts may be provided depending on the winding amount of the scrap to be removed and the space for installation. Good thing.
[0031]
