Description

    The present invention relates to a label sticking apparatus that has a suction plate that sucks a label and sticks the label sucked on the suction plate to an article.

2. Description of the Related Art Conventionally, there has been known a label sticking device that sticks a label that is wound in a roll shape and temporarily attached to a mount to an article that is conveyed on a conveyor by using a suction plate.
In this label affixing device, a label affixing method for avoiding the label from being affixed out of a predetermined position of an article by accurately adsorbing and holding the label at a predetermined aspiration position on an adsorption plate that adsorbs the label And the label sticking apparatus is devised (for example, refer patent document 1).
In addition, in the market where this labeling device is used, the shape of labels to be applied to articles has been diversified year by year. Conventionally, a lot of rectangular labels have been used. Labels that resemble the image of products such as apples, strawberries, and melons are often used.

In the conventional label sticking apparatus, after the label is sucked to the suction plate having the same shape and the same size as the label, the label is slid by a plurality of pressing means at the peripheral portion of the suction plate to thereby perform the predetermined on the suction plate. Since this has a complicated mechanism, the number of parts is high and the label attaching apparatus itself is large.
Further, when a plurality of labels having different sizes are used, it is assumed that an operation such as replacing the suction plate and adjusting the pressing means is required every time, and the operation is bothersome and problematic.
In addition, since the case of using an elliptical or other shape label is not considered, even if a pressing means is used for a label or a label having a curve smaller than the rectangular suction plate, the label is properly placed on the suction plate. Because the label cannot be held at the suction position, there is a problem that the label is stuck out of the predetermined position of the article.

Japanese Patent Laid-Open No. 02-57538

The present invention has been considered in view of the above problems. By providing a label guiding means for regulating and guiding the label to the regular suction position on the suction surface of the suction plate, the label has a smaller label and curve than the suction plate.

The suction detection sensor 44 outputs a signal to the main body 11.
The label guiding means 43 is formed integrally with a part of the suction surface 41 so as to protrude from the suction surface 41, and the part where the label guiding means 43 contacts the label L2 is a part of the peripheral edge of the label L2. Since it is formed like a cocoon of shape, it is in contact with the inside of the label guiding means 43 even when the label L2 is skewed when the label L2 is fed out in the direction of the arrow in FIG. The skew feeding is restricted, and the leading end of the label L2 is brought into contact with the shape of each tuft inside the label guiding means 43, so that it is guided to the normal suction position on the suction surface 41.
Thereafter, the suction plate 40 abuts on the article by the forward / backward movement of the piston rod 22 and the label L2 is applied, or air is supplied from the nozzle 23 into the suction plate 40 and the label L2 is sprayed and applied to the article. The label L2 can be attached without shifting to a predetermined position of the article.
As described above, by integrally forming the label guiding means 43 on a part of the suction surface 31, vibration due to the forward / backward movement of the piston rod 22 and friction in the case where the label L2 is pressed against the article are stuck. It has durability.

Next, a third embodiment of the present invention will be described with reference to the drawings.
FIG. 4 is a diagram for explaining the label guiding means in the third embodiment of the present invention. FIG. 4A is a schematic front view for explaining the suction plate from the suction surface, and FIG. It is a schematic right view for demonstrating an adsorption | suction board from the side.
The suction plate 50 detects a plurality of suction ports 52 for spraying or sucking the label L3 on the suction surface 51, label guiding means 53, and whether or not the label L3 is sucked by the suction surface 51 of the suction plate 50. The suction detection sensor 54 outputs a signal to the main body 11.
The label guiding means 53 is made of a magnetic metal or rubber, and forms a part of the periphery of the elliptical tip edge of the label L3, and is configured to be detachable from the attracting surface 51. FIG. Even when the label L3 is skewed when the label L3 is fed out in the direction of the arrow, the normal suction position on the suction surface 51 is controlled by the label L3 coming into contact with the inside of the label guiding means 53 and the skewing being restricted. Led to. At this time, depending on the size and shape of the label L3, the label guiding means 53 closes the suction port 52 that does not suck the label L3 on the suction surface 51 of the suction plate 50, so that the suction port 52 sucks the label L3. Since the label L3 is reliably adsorbed to the adsorbing plate 50, the label L3 can be prevented from dropping, and the label L3 can be stuck to a predetermined position of the article.
Thereafter, the suction plate 50 abuts on the article by the forward / backward movement of the piston rod 22 to attach the label L3, or air is supplied from the nozzle 23 into the suction plate 50, and the label L is sprayed and attached to the article. The label L can be attached without shifting to a predetermined position of the article.
As described above, the label guiding means 53 can be easily attached to and detached from the attracting surface 51 by using a magnetic metal or rubber, and a variety of labels can be obtained by changing the label according to the shape of the plurality of labels L3. The label L3 can be attached without shifting to a predetermined position of the article. Furthermore, when the label guiding means 53 is an elastic member such as a silicone sponge and is fixed to the suction surface 51 with an adhesive material, the label guiding means 53 can be made inexpensive, and the label L3 is pressed and pasted to the article. Further, the label guiding means 53 is elastically displaced, so that the label L3 can be surely pressed and attached to the article.

Next, a fourth embodiment of the present invention will be described with reference to the drawings.
FIG. 5 is a view for explaining the label guiding means in the fourth embodiment of the present invention. FIG. 5A is a schematic front view for explaining the suction plate from the suction surface, and FIG. It is a schematic right view for demonstrating an adsorption | suction board from the side.
FIGS. 6A and 6B are views for explaining attachment / detachment of the label guiding means in the fourth embodiment of the present invention. FIG. 6A is a schematic view in which the label guiding means is mounted, and FIG. It is the schematic for demonstrating removing a means.
The suction plate 60 detects a plurality of suction ports 62 for spraying or sucking the label L4 on the suction surface 61, label guiding means 63, and whether or not the label L4 is sucked by the suction surface 61 of the suction plate 60. The suction detection sensor 64 outputs a signal to the main body 11.
The label guiding means 63 has a box-shaped cylindrical shape, and is configured to be detachable from the suction plate 60 by forming a partial shape of the elliptical front end edge of the label L4 on the suction surface 61 side. Even when the label L4 is skewed when the label L4 is fed out in the direction of the arrow in FIG. 5A, the label L4 abuts on the inner side of the label guiding means 63 and the skew is restricted, so that the suction surface 61 is led to the normal suction position. At this time, depending on the size and shape of the label L4, the label guiding means 63 closes the suction port 62 that does not suck the label L4 on the suction surface 61 of the suction plate 60, so that the suction port 62 sucks the label L4. Since the suction force becomes strong, the label L4 is reliably sucked to the suction plate 60, so that the label L4 can be prevented from dropping and the label L4 can be stuck without shifting to a predetermined position of the article.
Thereafter, the suction plate 60 abuts on the article by the forward / backward movement of the piston rod 22 to attach the label L4, or air is supplied from the nozzle 23 into the suction plate 60, and the label L4 is applied to the article by spraying the label L4. The label L4 can be attached without shifting to a predetermined position of the article.
