By the way, in this conventional label sticking apparatus, the guide plate 113 is provided on the upstream side of the second label sticking mechanism 110, and the second portion La of the label L protruding from the article W is pressed downward and bent, Although the bending by the most upstream pressure roller 111A is surely performed, when the label L is pressed by the guide plate 113 or when pressed by the pressure roller 111 (111A to 111F), Due to this resistance, the first portion La of the label L may be shifted from the first sticking surface Wa of the article W, and there is a problem that the sticking of the label L due to the shift of the label L is concerned.
Moreover, in the said conventional pressure roller 111, when the label L is affixed on the article | item W, since the pressing force to the 2nd adhesion surface Wb of the article | item W is weak, the 2nd part Lb of the label L peels or the label L and There was a problem that a gap was generated in the vicinity of the ridgeline Ka of the article W.

The present invention has been made in view of the above-described problems, and ensures that the first portion of the label is attached to the article immediately before the article reaches the second label attaching mechanism, and the second label attaching mechanism ensures that the second label is attached by the second label attaching mechanism. It is an object of the present invention to provide a label sticking apparatus that reliably prevents a sticking failure in which a label is displaced or peeled when two parts are bent and stuck.
Furthermore, it aims at providing the label sticking apparatus which prevented that the 2nd part of a label peels or a clearance gap produces in the vicinity of the ridgeline of a label and articles | goods.

In order to solve the above problems, the label sticking device of the present invention is a label for sticking a label across the first sticking surface and the second sticking surface sandwiching the ridgeline of the corner of the article conveyed in a predetermined conveying direction by a conveyor. A first label for attaching a first part of a label corresponding to the first application surface of the article so that a second part of the label corresponding to the second application surface of the article protrudes from the article. An affixing mechanism, and a second label affixing mechanism that is provided on the downstream side of the first label affixing mechanism and that affixes the second part of the label protruding from the article from the ridgeline of the article and affixes it to the second affixing surface of the article In a label sticking device comprising:

Next, the first portion of the label is pressed against the first application surface of the article by the upstream pressing member provided immediately after the first label application mechanism. Therefore, the sticking of the first portion of the label to the article is ensured. Further, immediately before the second label sticking mechanism, the first portion of the label is further pressed against the first sticking surface of the article by the downstream pressing member. Therefore, the first part of the label is more reliably attached to the article.
Thereafter, in the second label sticking mechanism, the second portion of the label is bent from the ridgeline of the article and stuck on the second sticking surface of the article. In this case, the first portion of the label is pressed against the first sticking surface of the article by the upstream pressing member, and further pressed against the first sticking surface of the article by the downstream pressing member. The sticking of the first part to the article is further ensured, so that the situation in which the label is displaced or peeled is prevented by the resistance when the second label sticking mechanism is bent, and the sticking failure is surely caused. Is prevented.

  Then, if necessary, the second label sticking mechanism is arranged along the conveying direction of the article and has a contact surface that contacts the second portion of the label, and the corresponding contact surface is applied to the second portion. It comprises a plurality of pressure rollers that roll along the ridgeline of the article while being in contact with each other and are arranged in such a manner that the angle of the corresponding contact surface with respect to the second sticking surface of the article decreases sequentially from the upstream side to the downstream side. ing. Thereby, the second portion of the label is bent from the ridge line of the article while sequentially abutting on the abutting surfaces of the plurality of pressure rollers whose inclination angle gradually decreases, and is affixed to the second affixing surface of the article, The most downstream pressure roller is pressed against the second application surface of the article to complete the application. In this case, the first portion of the label is pressed against the first sticking surface of the article by the upstream pressing member even if it comes into contact with the plurality of pressure rollers and receives resistance, and further, the first portion of the article is pressed by the downstream pressing member. Since it is pressed against one sticking surface, the sticking of the first part of the label to the article is further ensured, so that a situation where the label is displaced or peeled is prevented and a sticking failure occurs. It is surely prevented. In addition, the pressure roller can be changed and adjusted as appropriate depending on the rigidity of the label base material, the base material, and the adhesive strength of the glue. can do.

  In addition, if necessary, the upstream pressing member is configured by a leaf spring that is supported at one end on the base side and bent at the other end in an arc shape and elastically contacts the first portion of the label. Since the first portion of the label is pressed by the leaf spring, the first portion of the label is more reliably attached to the article. Further, since the leaf spring is used, it can be formed smaller than the roller, and when the label is small, the label can be surely pressed, which is extremely effective.

Further, if necessary, the downstream pressing member is constituted by a pressing roller that rolls on the first sticking surface of the article and presses the first portion of the label. Since it is a pressing roller, it can be formed so as to press the entire or substantially entire surface of the first portion of the label, and the first portion of the label can be more reliably adhered to the article.

According to the label sticking device of the present invention, the first portion of the label is pressed against the first sticking surface of the article by the upstream pressing member, and further pressed against the first sticking surface of the article by the downstream pressing member. As a result, the first part of the label is more reliably attached to the article. Therefore, when the second label attaching mechanism is bent, the label is displaced or peeled off due to the resistance of the second label attaching mechanism. It is possible to prevent the occurrence of a sticking failure.
Furthermore, it can prevent that the 2nd part of a label peels or a clearance gap arises in the vicinity of the ridgeline of a label and articles | goods.
