The label printer P includes a label paper supply unit 2 on the rear side (right side in the drawing) and a stocker 13 on the front side (left side in the drawing), and prints on the label paper S fed out from the label paper supply unit 2. Then, the label L printed on the label paper S is discharged. The discharged label L is cut into a preset length dimension, and stocked in the stocker 13 in a stacked state from the top in the discharge order.

[Label paper supply unit 2]
The label paper supply unit 2 includes a label roll support unit 21 and a guide roller 22. A label roll R around which a continuous label sheet S is wound is rotatably supported by the label roll support portion 21. The label paper S pulled out from the upper surface side of the label roll R is tensioned so as not to be loosened by the guide roller 22, and is fed forward while being printed by the printing unit 3.

[Printer 3]
The printing unit 3 is provided so that the print head 31 and the platen roller 32 face each other in the vertical direction. The upper print head 31 performs printing on the upper surface side of the label paper S, and the platen roller 32 continuously conveys the printed label paper S forward. Since the label sheet S is wound in a roll shape, a curl that faces upward on the convex surface is attached, that is, the convex surface side is the printing surface.

[Cutter unit 4]
A cutter unit 4 that cuts a label L printed on the label paper S into a preset length dimension is disposed and fixed on the front side of the printing unit 3. Of course, the label L is a piece of paper with a curl to which a curl similar to the label paper S is attached. The cutter unit 4 accommodates upper and lower cutters 42 and 43 that are vertically opposed to each other in a case 41. An inlet 41a having a tapered guide is formed through the rear surface side of the case 41 with the upper and lower cutters 42 and 43 interposed therebetween, and the label L is continuously convex upward on the front side. A discharge port 41b for discharging is formed through.

  The upper cutter 42 is fixed to the upper portion of the case 41 so as to face downward. The lower cutter 43 is attached to the lower portion of the case 41 so as to be reciprocated by the power supplied from the power cord 44 and cooperates with the upper cutter 42 to cut the label L from the continuous label paper S. An abnormality detection sensor 45 is provided above the case 41. When an abnormality such as a paper jam is detected near the inlet 41a, a warning signal is issued and the operation of the label printer P is stopped. .

[Label stacking mechanism 1]
The label stacking mechanism 1 will be described based on an enlarged view (FIG. 2) schematically represented. The label stacking mechanism 1 is provided on the front side (downstream side) of the discharge port 41b, and mainly includes the guide member 11, the electrostatic removal brush 12, and the stocker 13, and the curl discharged from the discharge port 41b. The attached label L is stacked from the top in the order of discharge with the convex surface facing upward.

[Guide member 11]
The guide member 11 is an L-shaped resin piece that guides the label L discharged from the discharge port 41 b toward the stocker 13. The guide member 11 includes a vertical side portion 11v extending in a substantially vertical direction and a horizontal side portion 11w extending from the lower end to the front side. The vertical side portion 11v has a through hole 11a formed through, and is fixed to the front side of the case 41 so that the communication hole 11a communicates with the discharge port 41b. An elongated guide hole 11b through which the label L discharged from the communication hole 11a, that is, the discharge port 41b is inserted is formed in the lateral side portion 11w so as to penetrate vertically at a position lower than the discharge port 41b. On the upper side of the front edge portion of the guide hole 11b, an introduction piece 11c that extends obliquely rearward and guides the label L to the guide hole 11b is formed. In addition, you may form the guide member 11 with a metal.

[Static removal brush 12]
The electrostatic removal brush 12 is attached to the upper side of the communication hole 11a so as to be superimposed on the front side of the vertical side portion 11v, and extends downward from the support fixing portion 12a to cover the front side of the discharge port 41b. And a flexible brush bristle portion 12b constituting a warm shape. The brush bristle portion 12b functions as a pressing member that removes static electricity charged on the label L and presses the label L downward and behind the guide hole 11b in the lateral side portion 11w.

[Stocker 13]
The stocker 13 is formed below the guide member 11 so as to extend in the discharge direction of the label L, and is formed in a tray shape so that the labels L can be stacked in the discharge order. A plurality of ribs (not shown) extending in the front-rear direction are formed on the upper surface 13a of the stocker 13, and are slid so that the label L does not stick.

[Distance between guide member 11 and stocker 13 in height direction]
Each member constituting the label stacking mechanism 1 is as described above, but the label L discharged so as to be inserted through the guide hole 11b is stretched by its own winding rod, and as shown in FIG. The lateral side portion 11w of the guide member 11 is held so that the side e1 is pressed against the upper surface 13a of the stocker and the rear end side e2 is hooked on the front end lower portion 11d and the rear edge upper portion 11e of the guide hole 11b. An interval in the height direction of the stocker 13 is set. The label L is formed of a material and a thickness that can secure a waist that can be stretched with a roll. In order to prevent the rear end e2 from being easily released from being caught, it is necessary to be careful not to make the distance in the height direction too small. In addition, as described above, the “guide hole” includes a notch portion such as a comb shape as long as it can guide and hold the discharged label.

[Operation of the above embodiment]
The operation of the above-described embodiment will be described with reference to FIGS. 1 and 3 to 8.

  When the operation of the label printer P is started from a state in which the label sheet S is held between the print head 31 and the platen roller 32, the label sheet S is printed on the platen while being printed on the upper surface side by the print head 31. The roller 32 is fed forward. As shown in FIG. 1, the printed label L fed out from the printing unit 3 is introduced into the cutter unit 4 from the introduction port 11a and discharged from the discharge port 41b, and further pushes away the brush bristle portion 12b. However, it is inserted into the guide hole 11b and comes out above the stocker 13.

  As shown in FIG. 3, the label L inserted through the guide hole 11b further advances, and the front end e1 is pressed against the upper surface 13a of the stocker 13 and temporarily stops in a state of being inserted into the guide hole 11b. Then, printing on the upper surface of the label is completed. At this time, the label L is in a state in which static electricity is removed by the static electricity removing brush 12.

  Next, the cutter unit 4 is activated, and the lower cutter 43 moves upward to cut the label L from the label paper S as shown in FIG. The rear end side e3 of the cut label L is dropped downward by its own curl and pressing of the electrostatic removal brush 12, and is held in a state of being caught in the guide hole 11b as described above. The lower cutter 43 cuts the label L and then moves downward to return to the original position.

  In a state where the printed label L (hereinafter referred to as “preceding label Lp”) is held on the front end side e1 and the rear end side e2 by winding, as shown in FIG. A new label L (hereinafter referred to as “subsequent label Lf”) is discharged from the discharge port 41b while being printed out by the printing unit 3 while being forwarded. The front end side e3 of the succeeding label Lf advances above the preceding label Lp dropped downward and is pressed by the brush bristle portion 12b so as to cover the upper surface of the preceding label Lp.

  When the succeeding label Lf further advances and is inserted into the guide hole 11b, as shown in FIG. 6, the leading label Lp, in particular, the rear end side e2 is bent in the opposite direction to the curling heel at its curled heel and waist. While being pushed down, it is discharged in a state along the preceding label Lp. Therefore, the preceding label Lp is not pushed to be rounded by the succeeding label Lf.

  When the discharged length of the subsequent label Lf increases to some extent, the contact area with the preceding label Lp increases. Then, as shown in FIG. 7, the preceding label Lp was further strongly pressed by the increased frictional force with the subsequent label Lf and dropped onto the stocker 13, and the subsequent label Lf was dropped with the winding kite. The preceding label Lp is pressed from above. The succeeding label Lf is in a state in which the front end side e3 is along the preceding label Lp, so that it does not hit the preceding label Lp and be turned over.

  The subsequent label Lf is further advanced while maintaining the state of pressing the preceding label Lp from above, and is superimposed on the preceding label Lp as shown in FIG. Thereafter, the subsequent label Lf is cut off from the label paper S by the cutter unit 4 and the front end side e3 is pressed against the upper surface 13a of the stocker 13 as in the label L shown in FIG. The guide member 11 is held in a state of being caught in the guide hole 11b. Then, the operations as shown in FIGS. 5 to 8 are repeated, and the labels are further stacked.

[Features of label stacking mechanism 1]
The label stacking mechanism 1 has the following characteristic points.

  First, a guide member 11 having an elongated guide hole 11b that is provided at a position lower than the discharge port 41b and through which a label L with a winding rod that is formed so as to penetrate vertically is inserted, and a guide member 11 and is formed so as to extend in the discharge direction of the label L, and includes a tray-like stocker 13 on which the label L is stacked. e1 is pressed against the upper surface 13a of the stocker 13, the rear end side e2 is held in a state of being hooked on the front end lower part 11d and the rear edge upper part 11e of the guide hole 11b, and the subsequent label Lf discharged so as to overlap the upper face The feature is that the hooking to the guide hole 11b is released by being pressed downward.

  According to the first feature point, the preceding label Lp is pressed downward by the succeeding label Lf and is released in a state of being bent in the direction opposite to the curl, so that the rear end side e2 is rounded. It is prevented. Since the succeeding label Lf is guided by the guide hole 11b and the upper surface of the preceding label Lp held in the guide hole 11b, the front end side e3 is prevented from being rounded. Accordingly, the discharged labels are stacked while maintaining a state in which the printed surface can always be confirmed with the convex surface facing upward without curling and turning over. In particular, since the label stacking mechanism 1 does not require a driving device, the label stacking mechanism 1 is safe and has no fear of breakage.

  Secondly, an electrostatic removal brush 12 that presses the rear end side e2 of the label to be held against the rear edge upper side 11e of the guide hole 11b is disposed above the guide member 11. doing.

  According to the second feature point, the rear end side e2 of the held preceding label Lp is reliably prevented from floating upward by the brush bristle portion 12b of the electrostatic removal brush 12. This prevents a problem that the subsequent label Lf sinks below the preceding label Lp and the labels L are not stacked in the discharge order. In particular, since the electrostatic removal brush 12 is also used as a label pressing member, the label stacking mechanism can be configured at a lower cost than when a separate pressing member is provided.

[Modification of the above embodiment]
In the above embodiment, the guide member 11 and the stocker 13 are fixed, but both or either of them may be movable in the vertical direction so that the height can be adjusted. The appropriate distance between the guide member and the stocker varies depending on the length of the label L and the strength of the waist. By making these heights adjustable, it is possible to handle labels of various sizes. is there.

  In the above embodiment, the stocker 13 has a fixed length, but the length in the label discharge direction (front-rear direction) may be adjustable. The appropriate length of the stocker varies depending on the length of the label in the discharge direction. By making this adjustable, it is possible to deal with labels of various sizes.

  In the above embodiment, a label stacking mechanism for stacking labels, which are paper sheets with curling paper, is implemented. However, the present invention is not limited to labels, and may be applied to the case of stacking receipts and other paper sheets with paper winding paper. It can be done. In addition, the “roller” is not limited to the one that is actually wound in a roll shape, but when the same curving as when actually wound is made by passing through the inside of the roller mechanism, etc. Shall also be included.

  In addition, the paper-sheet-stacking mechanism with folds according to the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
