Description

  The present invention relates to a sheet sticking apparatus, and more specifically, it is possible to continuously supply a raw material in which an adhesive sheet (label) is temporarily attached to a strip-shaped release sheet and to waste an adhesive sheet. There is no sheet sticking device.

A well-known label sticking device (sheet sticking device) rolls a roll with a label temporarily attached to a strip-shaped release sheet, and peels the label at the tip of a peel plate or the like while feeding the roll. And the structure etc. which are stuck on a to-be-adhered body, etc. are adsorb | sucking the said peeled label.
However, in the case of a roll wound in a roll, the label has curling wrinkles. That is, the label is curled, and if the label is sucked and held by a vacuum grid or the like, the suction force leaks and the label cannot be held. Such inconvenience becomes apparent in the case of a label on the center side of the roll. Moreover, the roll-shaped original fabric also has a problem that a dedicated connection device (see Patent Document 1) is required to realize continuous feeding.

  Such an inconvenience or problem can be solved by the supply method described in Patent Document 2, for example. This document prepares a plurality of originals with labels attached to a strip-shaped release sheet and accommodated in a packing case. By connecting the starting end portion, it is possible to continuously feed out the original fabric.

Sandwich. Before and after this, the drawer region E of the previously used raw laminate U set in the supply position P is pulled out in the direction of arrow D in FIG. Interconnection is performed by bonding to the starting end portion of the body U (see an enlarged view of portion B in FIG. 1).

  When the automatic pasting mode is selected in the state where the above initial work has been completed, the motors M1 and M2 are driven to start feeding out the raw fabric R, and the printing information previously input by the printer 43 is applied to the label L. The printed label L stops at a predetermined position at the tip of the peel plate 36 while being printed.

  When it is detected that the adherend W has reached a predetermined position through a sensor (not shown), the label L that has stopped at the predetermined position at the tip of the peel plate 36 is peeled from the release sheet RL while being vacuumed. Then, the vacuum grid 42 is lowered and the label L is attached to the adherend W.

  The release sheet RL collected by the collecting means 37 by feeding out the original fabric R and applying the label L is collected in the collection box 50 while being folded zigzag at the folding position when the original fabric laminate U is formed. Will be. When the detection means (not shown) detects that the collection length of the release sheet RL has reached a certain amount, the release sheet RL is cut through the cutter 51 and the collection box 50 is discharged by the supply means (not shown). In addition, a new collection box 50 is set at a predetermined position.

  When detecting means (not shown) detects that all of the previously used original laminate U has been fed out, the transfer means 16 supplies support means 15 that supports the subsequent used original laminate U. A predetermined operation is performed so as to be located at position P. That is, the sprocket 20 is rotated leftward by a predetermined angle by a motor (not shown), and the support means 15 that supports the next packing case 25 is detected by a sensor (not shown) and set to the supply position P. The empty packaging case 25 is collected by a collecting means (not shown).

  When the support means 15 for supporting the raw fabric laminate U used in the subsequent manner moves to the supply position P, the support means 15 that has been waiting on the lower side of the transfer means 16 at the same time is inverted upward, A new raw fabric laminate U is supported by the support means 15. At this time, the pull-out area E of the original fabric laminate U sent to the supply position P and the starting end portion of the newly set original fabric laminate U are connected via the adhesive tape T in the same manner as described above.

  As shown in FIG. 1, the support means 15 is tilted so that the upper end of the upright portion 19 is located on the left side of the lower end when the original fabric R is extended, that is, the upright portion 19 is extended out of the original fabric R. It is maintained in an inclined state toward the downstream side in the direction, whereby one end (the left end in FIG. 1) side of the raw fabric laminate U is supported by the upright portion 19 via the packing case 25. Accordingly, it is possible to smoothly feed out the original fabric R as compared with the case where the original fabric R is pulled out and fed out. Further, the original fabric laminate U is pulled out while being guided on both sides in the width direction by the side walls 25E of the packaging case 25, and inadvertent movement along the width direction is restricted, and the original fabric R that causes a decrease in label sticking accuracy. Meandering can be prevented.

  Therefore, according to such an embodiment, the raw fabric R can be fed endlessly, and the effect that the label L can be continuously stuck to the adherend W without stopping the operation of the sheet sticking apparatus 10 is achieved. Get.
