Description

  The present invention relates to a small winding device that transports a label continuous body, in which a plurality of label pieces are continuously attached to a mount, and performs small winding as a small winding roll. It is related with the small winding apparatus which peels off the label piece located in board | substrate from a mount, and carries out small winding.

  Conventionally, a roll-shaped continuous label body is printed by a printing machine in a manufacturing stage and wound up in a roll shape as a large-diameter original roll. Usually, the length of the original roll wound up by a printing machine is , The length of the roll-shaped label continuous body used for the label applicator is about 150 to 300 m, so that the original roll can be used with the label applicator. In addition, a small winding device that uses a small winding roll as a small diameter roll is used.

  In addition, when a small roll is used in a label applicator, the label piece between the label peeling part and the take-up part of the label applicator is not necessary when setting the label applicator, so-called label set loss. Since it cannot be used as a part, there has been proposed a small winding device that peels off a label piece of about one round of outer periphery, which is a label set loss part, from a backing sheet (for example, see Patent Document 1).

  In the small winding device of Patent Document 1, the sheet is moved below the peeling plate (313) (the numbers in parentheses indicate the symbols described in Patent Document 1. The same applies hereinafter), and the original sheet (3) is conveyed. The route is changed so as to be folded by the peeling plate (313). The label (2b) folded back and peeled off by the peeling plate (313) comes into contact with the peeling roller (320) rotating at high speed, and is blown into the label storage box (318) and stored. In this small winding device, the label (2b) for the outer periphery of the small winding roll (4) is peeled off from the separator (1), whereby the setting to a labeling machine or the like can be easily performed. It becomes like this.

The slack 25 (see FIG. 6) is provided on the label continuum 20 in the means 60.

(Configuration of peeling means 60)
The whole structure of the peeling means 60 is demonstrated in detail based on FIG.
As shown in FIG. 4, the peeling means 60 is constituted by a peeling member 61, a suction roller 62, a collection roller 63 and a movable unit 70, and an unnecessary label piece that becomes a label set loss portion 32 from the conveyed label continuous body 20. 21 is peeled and collected.

The peeling member 61 is a member formed in a plate shape, and supports the label continuous body 20 from the mount 22 side by the upper support surface 61a. A sharpened portion 61 b that is sharpened toward the downstream side is formed at the downstream end of the peeling member 61. The sharp portion 61b is a corner portion where the support surface 61a and a tip surface 61c inclined at an angle θ (see FIG. 3) with respect to the support surface 61a intersect, and are sharpened at an acute angle. In the peeling member 61, when peeling off the label piece 21, the label piece 21 is bent by bending the transport path of the label continuous body 20 at an acute angle with the surface on the mount 22 side inward with the tip of the sharpened portion 61b as a base point. Is peeled off from the mount 22.
That is, the peeling member 61 conveys and guides the mount 22 to which the label piece 21 is attached while being bent at an acute angle, and is along a transfer path 64 (see FIG. 3) in which the mount 22 is bent at an acute angle. When conveyed, the label piece 21 temporarily attached to the surface of the mount 22 operates so as to be peeled off from the mount 22 by its own waist strength (rigidity).

  The suction roller 62 is rotatably provided on the label piece 21 side of the label continuous body 20, and faces the sharpened portion 61 b of the peeling member 61 with the label continuous body 20 interposed therebetween. A vacuum pump 66 (see FIG. 3) is connected to the suction roller 62 via a valve 65 (see FIG. 3), and an outer peripheral surface 62a of the suction roller 62 communicates with the vacuum pump 66 (see FIG. 3). A number of suction holes 67 are provided. The plurality of suction holes 67 can vacuum suction (suction) the surface of the label piece 21 peeled off from the mount 22, whereby the suction roller 62 removes the label piece 21 from its outer periphery while reversing the front and back of the label piece 21. Transition to the surface 62a.

  The collection roller 63 is provided on the side opposite to the label continuous body 20 so as to face the suction roller 62, and is driven by the rotation of the suction roller 62. The collection roller 63 transfers the label piece 21 from the suction roller 62 to the outer peripheral surface 63a by adhering the adhesive layer 23 (see FIG. 2) of the label piece 21 vacuum-sucked by the suction roller 62 to the outer peripheral surface 63a. And collect. Further, the collecting sheet constituting the outer peripheral surface 63a can be wound around the collecting roller 63 in an exchangeable manner. It is preferable to use an inexpensive paper material (for example, newspaper) for the collection sheet.

  The movable unit 70 includes a movable roller 71, an air injection unit 72, and a receiving unit 73. The movable roller 71, the air injection unit 72, and the receiving unit 73 are integrated as one unit when the label piece 21 is peeled off. To work.

  The movable roller 71 is provided on the label piece 21 side of the conveyed label continuum 20 and in the vicinity of the downstream side of the suction roller 62. The movable roller 71 can move forward and backward with respect to the label continuous body 20 to be conveyed. In this example, as shown by the white arrow in FIG. 4, the movable roller 71 can move toward the vicinity of the lower portion of the sharp portion 61b. is there. When the label piece 21 is peeled off, the movable roller 71 advances toward the label continuous body 20 and enters the vicinity below the sharpened portion 61b using the inclination of the tip end surface 61c. As a result, the movable roller 71 bends the conveyance path of the label continuum 20 at an acute angle with the tip of the sharpened portion 61b as the base point and the surface on the mount 22 side as the inner side.

  The air injection unit 72 is a pipe provided on the upper portion of the movable roller 71 via a support body 75 and extends in parallel with the axial direction of the movable roller 71. The air injection portion 72 is provided with a large number of injection holes 76 arranged along the axial direction. The numerous injection holes 76 are connected to an air pressure source 78 (see FIG. 3) via a valve 77 (see FIG. 3), and the adhesive layer 23 of the label piece 21 peeled off from the mount 22 (see FIG. 2). Air is sprayed to the side to cause the label piece 21 to warp and press the label piece 21 against the outer peripheral surface 62 a of the suction roller 62.

  The receiving portion 73 is a member formed in a dish shape from below the air injection portion 72 toward the downstream side of the label continuous body 20, and is fixed to the support body 75. The receiving portion 73 receives the label piece 21 that has fallen without being attracted to the outer peripheral surface 62 a of the suction roller 62.

  It should be noted that the form and the number of elements constituting the “peeling means” according to the present invention are not particularly limited to the peeling means 60 shown in FIG. 4, and can be arbitrarily changed according to the required specifications. is there.

(Operation example of the small roll device 40)
Next, an operation example of the small winding device 40 by the control unit 56 will be described based on the flowchart shown in FIG. 5 and the action explanatory diagrams shown in FIGS. The present invention is not limited to this operation example.

  As shown in FIG. 5, the process starts in step SS, and in step S1, the winding shaft 42, the upstream-side transport roller 43, the downstream-side transport roller 45, and the slitter 53 are rotated so that the label continuous body to the winding shaft 42 is obtained. Start winding 20A.

  In step S2, it is determined whether or not the number measured by the number counting means 47 is a set number. Here, the set number is a number set according to the number of label pieces 21 wound around one small roll 30. If the number of label pieces 21 is not the set number, step S2 is repeated.

  On the other hand, when the number of the label pieces 21 is the set number in step S2, the process proceeds to step S3, and the operations of the winding shaft 42, the upstream side conveyance roller 43, the downstream side conveyance roller 45, and the slitter 53 are stopped. Stop taking. In step S4, the upstream-side transport roller 43 and the suction roller 62 are rotated.

  At this time, as shown in FIG. 6, only the label continuous body 20 upstream of the nip roller 46 is transported by the rotation of the upstream transport roller 43, so that the label continuous between the peeling member 61 and the nip roller 46. The body 20 relaxes.

  Returning to FIG. In step S5, the transport amount measuring means 51 determines whether or not the continuous label body 20 has been transported by a predetermined amount. Here, the predetermined amount is a conveyance amount of the label continuum 20 corresponding to the slack 25 necessary for peeling the label piece 21. If the label continuum 20 is not conveyed by a predetermined amount, the slack 25 is insufficient and step S5 is repeated.

  On the other hand, if the label continuous body 20 has been conveyed by a predetermined amount in step S5, the process proceeds to step S6, the slack 25 is used to move the movable roller 71 to the vicinity below the sharp portion 61b, and the air injection unit 72 Inject air. Further, in step S7, the winding shaft 42, the downstream conveying roller 45, and the slitter 53 are rotated, and the winding of the label continuous body 20A onto the winding shaft 42 is resumed.

  As a result, as shown in FIG. 7, the conveyance path of the label continuum 20 is sharpened (bending angle indicated by θ <b> 1) by the movement of the movable roller 71 and the sharp part 61 b that is sharpened at an angle θ (see FIG. 6). And the downstream portion of the label piece 21 peels from the mount 22. At the same time, as shown in FIG. 8, when the air hits the pressure-sensitive adhesive layer 23 side of the label piece 21 peeled off from the mount 22, the label piece 21 is warped and pressed against the outer peripheral surface 62a of the suction roller 62, and By being vacuum-sucked by the suction roller 62, it is completely peeled off from the mount 22 and is further easily transferred to the outer peripheral surface 62 a of the suction roller 62.

  Further, as shown in FIG. 9, as the suction roller 62 rotates, the adhesive layer 23 of the label piece 21 vacuum-sucked by the suction roller 62 adheres to the outer peripheral surface 63 a of the collection roller 63. As a result, the label piece 21 is transferred from the suction roller 62 to the collection roller 63 and collected on the outer peripheral surface 63 a of the collection roller 63.

  Returning to FIG. In step S <b> 8, the transport amount measuring unit 52 determines whether the label continuous body 20 has been transported by a predetermined amount. Here, the predetermined amount is the transport amount of the label continuum 20 corresponding to the length L of the label set loss portion 32. If the label continuous body 20 is not conveyed by a predetermined amount, step S8 is repeated.

  On the other hand, if the label continuous body 20 has been conveyed by a predetermined amount in step S8, the process proceeds to step S9, where the rotation of the suction roller 62 and the vacuum suction are stopped, and at the same time, the winding shaft 42, the upstream conveyance roller 43, and the downstream conveyance. The operation of the roller 45 and the slitter 53 is stopped, and the winding is stopped.

  Next, in step S10, the movable roller 71 is moved backward to eliminate the slack 25 of the label continuous body 20, and then the winding shaft 42, the upstream conveyance roller 43, the downstream conveyance roller 45, and the slitter 53 are rotated. The winding of the label continuous body 20A onto the winding shaft 42 is resumed.

  Here, the means for eliminating the slack 25 of the label continuous body 20 can be selected from various means, but in order to eliminate the slack 25 smoothly, the downstream transport speed is set to V1, and the upstream transport speed. When V2 is V2, it is desirable to transport the label continuum 20 so that the relationship of V1> V2 is satisfied (see FIG. 10).

  In step S11, when the rear end of the label set loss portion 32 is transported to the position of the cutter 55, the winding shaft 42, the upstream transport roller 43, the downstream transport roller 45, and the slitter 53 are stopped for winding. Is stopped, and the continuous label body 20A is cut by the cutter 55. This completes the operation of the small winding device 40.

(Effect of embodiment)
The effect of the small winding device 40 described above will be described.
According to the small roll device 40, the label piece 21 is peeled from the mount 22 by bending the transport path of the label continuous body 20 by the peeling member 61, and the label piece 21 peeled from the mount 22 is vacuumed by the suction roller 62. The label piece 21 can be adsorbed to the outer peripheral surface 62a by suction. Therefore, the conventional label storage box becomes unnecessary, space saving can be realized, and the small winding device 40 can be downsized.

  Moreover, since the conveyance path of the label continuous body 20 is bent at an acute angle with the surface on the side of the mount 22 as the inner side with the tip of the sharp portion 61b of the peeling member 61 as a base point, the label piece 21 can be easily peeled off from the mount 22 Can do.

  Further, the label piece 21 adsorbed on the outer peripheral surface 62 a of the suction roller 62 can be transferred to the collection roller 63 and collected. As a result, a large amount of label pieces 21 can be efficiently recovered simply by replacing the newspaper or the like constituting the outer peripheral surface 63a of the recovery roller 63.

  Further, the label piece 21 peeled off from the mount 22 can be warped by the air ejecting section 72 and can be satisfactorily attracted to the outer peripheral surface 62 a of the suction roller 62.

  Further, the movable roller 71 can easily bend the conveyance path of the label continuum 20 at an acute angle, and the label piece 21 can be more favorably peeled from the mount 22, and the movable roller 71 and the air injection unit By configuring 72 as one movable unit 70, the structure of the peeling means 60 can be simplified, and the accuracy of the operating positions of the movable roller 71 and the air injection unit 72 can be increased.

  In addition, since the receiving unit 73 is provided in the movable unit 70, even if the label piece 21 is not attracted to the outer peripheral surface 62a of the suction roller 62 for some reason, the receiving piece 73 is dropped. 21, the dropped label piece 21 falls into the apparatus and cannot be recovered, or the label piece 21 is mixed into the label continuous body 20 in the middle of conveyance and cannot be used as the small roll 30 (product). There is no worry of doing.

  Furthermore, if the label continuous body 20 is transported and the slack 25 is eliminated while the downstream transport speed V1 is higher than the upstream transport speed V2, the slack 25 of the label continuous body 20 can be smoothly eliminated. it can.

  On the other hand, if the downstream transport speed V1 and the upstream transport speed V2 are set to the same magnitude, the slack 25 is not eliminated. Further, it is possible to reduce the slack 25 by transporting only the downstream label continuum 20, and when the slack 25 is eliminated, the upstream label continuum 20 can be transported. Since a problem such as a strong tension acting on the label continuum 20 is likely to occur at the start of conveyance of the label continuum 20, this is not a desirable means.

  In this respect, if the label continuous body 20 is transported in a state where the downstream transport speed V1 is higher than the upstream transport speed V2, the slack 25 can be gradually eliminated, and the label continuous body 20 has a strong tension. There is no worry of acting. As a result, the slack 25 of the continuous label body 20 can be eliminated smoothly.

  As mentioned above, although this invention was demonstrated using embodiment, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment.
