FIG. 5 shows an open state in which the cam follower 74 rides on the peak portion of the cam 73 and the tip portion of the holding member 76a is separated from the holding member 76b.
[0051]
The postcard and label separation operation by the postcard holder body 60 and the label holder body 70 having the above-described configuration will be described with reference to FIG.
[0052]
First, when the postcard detection sensor 52 detects the passage of the postcard 11, the signal is transmitted to the drive system of the postcard holder body 60, and the postcard 11 is inserted between the holding member 66a and the holding member 66b. Then, the wheel 61 starts to rotate. Then, the cam follower 64 moves from the state shown in FIG. 5 to the valley portion of the cam 63, and as shown in FIG. 6A, the two holding members 66a hold the leading end portion of the postcard 11, and in this state The wheel 61 continues to rotate.
[0053]
On the other hand, when the label detection sensor 53 detects the passage of the label 12, the signal is transmitted to the drive system of the label holder body 70, and as shown in FIG. The wheel 71 begins to rotate at the timing when the leading ends of both edges of the label 12 attached to the held postcard 11 are inserted between the holding member 76a and the holding member 76b. Then, the cam follower 74 moves from the state shown in FIG. 5 to the valley portion of the cam 73, and the two holding members 76a hold the end portions of the both edges of the label 12 as shown in FIG.
[0054]
As shown in FIG. 6B, the postcard 11 is generally in close contact with the wheel 61 while being curved by the guide member 67, and both edge portions of the label 12 are peeled off by the label both-end peeling portion 30 in advance. The holding member 76 having an edge-shaped tip is surely inserted between the postcard 11 and the label 12, and the leading end portions of both edges of the label 12 are surely secured by the holding member 76a. Can be held in.
[0055]
The wheel 61 and the wheel 71 continue to rotate while holding the postcard 11 and the label 12 respectively, and when the postcard 11 and the label 12 are rotated to a position where the postcard 11 and the label 12 are completely separated, the cam follower 64 is connected to the cam 63 on the postcard holder body 60 side. From the valley portion to the mountain portion, the holding member 66a opens the postcard 11 as shown in FIG. Even after the postcard 11 is opened, the wheel 61 continues to rotate, and stops exactly one rotation until the state shown in FIG. The released postcard 11 slides down the slider 81 (see FIG. 1) and is stacked on the postcard stack unit 80.
[0056]
On the other hand, the wheel 71 on the side of the label gripping body 70 continues to rotate while holding the label 12 and conveys it to the label winding unit 90. As will be described in detail later, when the label 12 is conveyed to a predetermined position of the label winder 90, the cam follower 74 on the label gripping body 70 side moves from the valley portion of the cam 73 to the peak portion, and the holding member 76a. Opens the label 12. Even after the label 12 is released, the wheel 71 continues to rotate, and stops exactly one turn to the state shown in FIG.

[0062]
The released label 12 is pressed against the wheel 71 by the presser roller 91 and is transported between the transport roller 94 and the guide roller 93 along the guide member 92 by the rotation of the wheel 71 as shown in FIG. Is done. The press roller 91 and the guide roller 93 may be made of, for example, Teflon (registered trademark) so that the label 12 does not adhere.
[0063]
The label 12 is finally wound around the paper tube 96 by the adhesive force of the label itself. The paper tube 96 is installed such that its center can move in the vertical direction as shown by a two-dot chain line in FIG. Further, when a certain amount or more of the label 12 is wound, the winding diameter detection sensor 97 detects this, and the apparatus automatically stops and prompts replacement of the paper tube 96.
[0064]
According to the apparatus configuration of the present example described above, the label 12 and the postcard 11 are automatically and continuously separated only by storing the postcard 11 with the label 12 affixed in the postcard supply unit 10. The label 12 can be peeled off very efficiently. Further, since the label 12 and the postcard 11 are forcibly separated in a state where they are separately held, the label can be peeled off at high speed and reliably. Furthermore, the consumable item is only the paper tube of the label winder, and maintenance is extremely easy.
[0065]
In the above-described embodiment, a postcard has been described as an example of paper sheets. However, the present invention can be widely applied to sealed letters, cards, and the like.
[0066]
