Description

  The present invention relates to an apparatus for winding a label peeled off from a postcard, a sealed letter, a card or the like by an automatic label peeling apparatus, and an automatic label peeling apparatus provided with the label winding apparatus.

  For example, postcards in which confidential information that is not desired to be known to humans, such as account numbers and personal identification numbers, are often mailed in a state where a label is attached to the secret information portion and concealed. Then, the recipient needs to peel off the label from the postcard that has been mailed and check the contents. Usually, the label is peeled off at the recipient, and the processing capacity is as low as about 30 sheets / minute, and the work efficiency is poor.

  In view of this, the present inventors have proposed an automatic label peeling apparatus that can peel a label at high speed and reliably from a paper sheet to which the label is attached (see Patent Document 1).

JP 2000-142918 A

  The automatic label peeling apparatus described in Patent Document 1 includes a label winder as shown in FIG. 8 as means for collecting a large amount of labels separated from paper sheets.

  That is, the label 81 separated from the paper sheet is transported between the rubber roller 83 and the label take-up holder 84 by the plurality of rollers 82 from the label gripping body 76, and finally the label is taken up by the label take-up holder 84. It is wound by its own adhesive strength.

  The label take-up holder 84 is pressed against the rubber roller 83 so that the center of the label take-up holder 84 can move up and down as indicated by the two-dot chain line in FIG. It has become.

  In the configuration as described above, since a large amount of labels are separated from the paper sheets at high speed and wound on the label winding holder 84, the label winding holder 84 needs to be frequently replaced. For this reason, the label take-up holder 84 must be easily removable.

  As a simple method for supporting the label take-up holder so as to be easily removable, for example, a method for supporting the label take-up holder from the left and right freely by a spring force can be considered. However, in this method, the label take-up holder is likely to be shaken by the pressing force from the rubber roller. If the spring force is strengthened and supported to prevent shaft runout, it becomes difficult to remove the label take-up holder.

  If the label take-up holder is swung, the left and right pressing forces of the rubber roller against the label take-up holder will be different, causing the label to be unwound to the label take-up holder and causing troubles such as machine stoppage. Become.

  The above problem is particularly likely to occur when winding a label that is not web-like but discontinuously discharged, and can be said to be a problem peculiar to an automatic label peeling apparatus that separates a large amount of labels from paper sheets at high speed.

  Therefore, in view of the above circumstances, the present invention provides a label winder that can easily remove the label winder holder and can effectively prevent the shaft roll of the label winder holder, and this label winder. It is an object of the present invention to provide an automatic label peeling apparatus that can prevent a machine stop due to a trouble in a label winding unit.

The label winding holder is sandwiched by the sandwiching means A and the sandwiching means B and supported around the rotation shaft,
The clamping means A is fixed to the rotating shaft, and the clamping means B has a structure that can be detached from the rotating shaft,
The end of the rotating shaft on the clamping means A side is placed on a plurality of bearing rollers in a state where movement in the axial direction is constrained,
The end of the rotating shaft on the clamping means B side is simply placed on a plurality of bearing rollers.
Further, the axial movement of the rotary shaft is restricted by providing a pair of set collars at the end of the rotary shaft on the clamping means A side so as to sandwich the plurality of bearing rollers. .

  Moreover, the label automatic peeling apparatus of the present invention is at least a means for automatically peeling a label attached to a paper sheet and a label automatic peeling apparatus having a label winding means for winding the peeled label. The label winding device of the present invention is used as the label winding means.

According to the label winding device of the present invention, the rotating shaft that supports the label winding holder is supported by simply placing both ends of the rotating shaft on a plurality of bearing rollers so as to freely rotate. Can be easily removed with the label take-up holder. In addition, since one of the holding means (holding means B) for supporting the label winding holder on the rotating shaft has a structure that can be detached from the rotating shaft, the label winding holder can be replaced by removing the holding means B. It can be done easily.
In addition, the rotating shaft that supports the label take-up holder is not supported by a spring or the like from the lateral direction, but is supported on a plurality of bearing rollers in a state in which movement in the axial direction is constrained. The label take-up holder does not shake due to the pressing force from the roller, and troubles such as machine stoppage due to the labels being taken up unevenly can be prevented.

  In addition, by incorporating the label winding device of the present invention into the label automatic peeling device, an automatic label peeling device that can prevent machine stoppage due to trouble in the label winding portion is realized.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a front view showing a label winding device according to an embodiment of the present invention in a partial cross section. In the figure, 1 is a rubber roller, 2 is a cylindrical label winding holder, 3 is a shaft (rotating shaft), 4 is a fixed cone with a hook fixed to the rotating shaft 3 (corresponding to the clamping means A), 5 A slide cone with a hook detachable from the rotary shaft 3 (corresponding to the holding means B), 6a and 6b are set collars, and 7 and 8 are bearing rollers.

  This label winding device winds a label conveyed between the rubber roller 1 and the label winding holder 2 around the label winding holder 2 by the adhesive force of the label itself.

  The label take-up holder 2 is supported around the rotary shaft 3 by being sandwiched on both sides by a fixed cone 4 with a hook and a slide cone 5 with a hook. In this example, removable cylindrical members 9a and 9b are interposed between the label winding holder and each cone to reinforce the label winding holder 2 made of a paper tube or the like.

  The material of the label take-up holder 2 is not particularly limited. However, since the label take-up holder is usually disposable after taking up the label, an inexpensive paper tube or resin is preferable.

  The fixed cone 4 with the hook is fixed to the rotary shaft 3 and supports one end of the label take-up holder 2 via the cylindrical member 9a. Moreover, the slide cone 5 with a hook is fixed to the rotating shaft 3 and can be further removed, and supports the other end of the label take-up holder 2 via a cylindrical member 9b.

  Fixing the slide cone 5 with the hook to the rotary shaft 3 is performed by the cone mounting boss 10. This mechanism will be described with reference to FIGS. FIG. 2 is a partial cross-sectional view showing a state in the middle of fixing by the cone mounting boss 10, and FIG. 3 is a cross-sectional view taken along the C-C 'plane in FIG.

  The slide cone 5 with a hook is provided with two guide pins 5b, and these guide pins 5b are inserted into guide holes on the cone mounting boss 10 side. Thereby, the front-end | tip of the two compression springs 10a attached to the cone attachment boss | hub 10 is inserted by the groove | channel provided in the slide cone 5 with a hook (refer FIG. 1). In FIG. 1, in order to express this insertion state, the slide cone 5 with cone and the cone mounting boss 10 are shown in a cross section on the D-D ′ plane in FIG. 3.

  Then, as shown in FIG. 2, with the knock pin 3 a attached to the rotating shaft 3 being inserted into the guide groove 10 b provided in the cone mounting boss 10, the cone mounting boss 10 together with the flanged slide cone 5 is moved. The knock pin 3a is accommodated in the end 10c of the guide groove 10b by rotating in a predetermined direction. Thereby, the slide cone 5 with a hook is fixed to the rotating shaft 3 by the spring force of the compression spring 10a attached to the cone mounting boss 10, and supports the end portion of the label take-up holder 2 via the cylindrical member 9b. be able to.

  When removing the flanged slide cone 5 from the rotary shaft 3, the procedure may be reversed. That is, when the cone mounting boss 10 is rotated together with the hooked slide cone 5 in the direction opposite to that when the knock pin 3a is accommodated in the end portion 10c of the guide groove 10b, the cone mounting boss 10 is easily separated by the force of the compression spring 10a. Then, the cone mounting boss 10 and the slide cone 5 with the hook can be detached from the rotary shaft 3.

  As shown in FIG. 1, the rotating shaft 3 that supports the label take-up holder 2 by the mechanism as described above is rotatably supported at its both ends on a plurality of bearing rollers. FIGS. 4A and 4B are diagrams for explaining this support state, and show cross sections along the A-A ′ plane and the B-B ′ plane in FIG. 1, respectively.

  A pair of set collars 6a and 6b are attached to the end of the rotary shaft 3 on the side of the fixed cone 4 with a flange at a predetermined interval (corresponding to the width of the bearing roller 7). Then, the bearing roller 7 is sandwiched between the set collars 6a and 6b, and the rotary shaft 3 is mounted on the two bearing rollers 7 and 7 attached to the base 11 at a predetermined interval as shown in FIG. Placed. Thereby, the edge part by the side of the fixed cone 4 with a hook of the rotating shaft 3 is supported in the state which restrained the movement of the axial direction (horizontal direction).

  On the other hand, since the cone mounting boss 10 and the flanged slide cone 5 need to be removed on the rotating shaft 3 side with the flanged slide cone 5 side in order to replace the label take-up holder 2, the above set collar is attached. Not. Then, the end of the rotary shaft 3 on the side of the slide cone 5 with the flange is simply placed on the two bearing rollers 8 and 8 attached to the base 12 at a predetermined interval as shown in FIG. Has been supported.

  The bases 11 and 12 are supported in the vertical direction by a spring mechanism (not shown), and the label take-up holder 2 supported around the rotating shaft 3 is pressed against the rubber roller 1 by the spring force of the spring mechanism. As a result, the label take-up holder 2 can move in the vertical direction in accordance with the take-up of the label, and can take up a large number of labels continuously.

  According to the configuration described above, the rotary shaft 3 that supports the label take-up holder 2 is supported by simply placing both ends thereof on a plurality of bearing rollers. It can be easily removed by lifting the two together. Further, since one end of the label take-up holder 2 is supported by a slide cone 5 with a hook that can be easily removed from the rotary shaft 3, the label take-up holder 2 can be replaced by removing the slide cone 5 with a hook. It can be done easily.

  In addition, since the rotary shaft 3 that supports the label take-up holder 2 is supported on a plurality of bearing rollers, the label take-up holder 2 does not run out due to the pressing force from the rubber roller 1, and the label is removed. Uneven winding can be prevented.

  The label winding device of the present invention is not limited to the above-described embodiment, and appropriate design changes can be made within the scope of the gist of the present invention.

  As a specific example, for example, a configuration as shown in FIG. 5 or 6 can be used as a means for restraining the axial movement of the end of the rotating shaft on the clamping means A side.

  In the previous example, the bearing roller is sandwiched between a pair of set collars, but FIG. 5 is an example in which the set collar is sandwiched between bearing rollers. That is, only one set collar 6 is attached to the end of the rotary shaft 3 on the fixed cone 4 side with a flange, while the bearing rollers 7 are arranged in two rows with a spacer 13 having the same thickness as the set collar 6 interposed therebetween. By using a total of four, the movement of the rotating shaft 3 in the axial direction is restricted.

  FIG. 6 shows an example in which one of the pair of set collars is replaced with a hooked fixed cone 4. That is, the bearing roller 7 is sandwiched between the end 4 a of the fixed cone 4 with the hook and the set collar 6. In addition, although aluminum is normally used for the fixed cone 4 with a hook for weight reduction, in the structure of FIG. 6, in order to prevent abrasion of the fixed cone 4 with a hook, it is good to use stainless steel similarly to a set collar.

  In the previous example, the rubber roller side is fixed and the label take-up holder is pressed against it by a spring force. Conversely, the label take-up holder side may be fixed and the rubber roller pressed against this by a spring force or the like. .

Next, the automatic label peeling apparatus of the present invention will be described.

  In FIG. 7, 71 is a postcard supply unit, 72 is a postcard to which a label is attached, 73 is a transport unit, 74 is a sensor unit, 75 is a postcard holder body (paper sheet holder body), and 76 is a label. The tail barrel portion 77 is a sorting and collecting mechanism. Reference numeral 78 denotes a label winder, which uses the above-described label winder of the present invention.

  The outline of the automatic label peeling apparatus will be briefly described with reference to FIG. 7. First, the postcard 72 is stored in the postcard supply unit 71 in a stacked state with the surface to which the label is attached facing up. The transport unit 73 takes out the postcards 72 from the postcard supply unit 71 one by one at a predetermined interval, and transports the postcards 72 to the postcard holder body unit 75. The postcard gripping body 75 grips the front end of the postcard 72 based on the signal from the sensor for detecting the postcard of the sensor unit 74, and then rotates clockwise in the figure. Based on the signal from the sensor for detecting the label of the sensor unit 74, the label gripping body 76 grips the leading end of the label affixed to the postcard held by the postcard gripping body 75, and thereafter Rotate clockwise.

  As described above, the postcard holder body 75 rotates while holding the leading end portion of the postcard, and the postcard and the label 76 are separated by rotating the label holding body portion 76 while holding the leading end portion of the label. Is done. The separated label is conveyed between the rubber roller 1 and the label take-up holder 2 of the label take-up device of the present invention described above by the plurality of rollers 82 as shown in FIG. Finally, the label is wound around the label winding holder 2 by the adhesive force of the label itself.

  At this time, in the label winding device of the present invention, since the label winding holder does not cause shaft wobbling, it is possible to prevent troubles such as machine stoppage due to uneven winding of the label which has been regarded as a problem in the past. This can improve the reliability of the automatic label peeling apparatus.
