Description

  The present invention relates to a label attaching device for attaching a label to a product conveyed on a conveying means such as a conveyor, and more specifically, regardless of the size, shape, etc. of the product, and the application of the product etc. with a simple operation. The present invention relates to a label affixing device that can affix a label to any surface such as an upper surface, a side surface, and a lower surface of a body.

  Most conventional label applicators are dedicated machines, and are designed to apply labels to predetermined places on an adherend. And the position which can be affixed is also limited to any one of the upper surface, side surface and lower surface of the product.

  Therefore, when constructing a system for applying a label to an adherend, a dedicated label applicator is disposed along the conveyor line that conveys the adherend, and the attachment position varies. In addition, replace the label applicator for upper surface application, side surface application, lower surface application, etc., or place multiple types of label applicators for upper surface application, side application, and lower application on one conveyor line in advance. It was necessary to keep it.

  Since multiple types of labeling devices must be arranged or replaced, not only a considerably large arrangement space is required, but also multiple expensive labeling devices are purchased, resulting in a significant increase in overall costs. There was a disadvantage.

In view of this, there has been disclosed a label sticking device in which a single label sticking device can attach labels to a plurality of surfaces such as an upper surface, a side surface, and a lower surface of an adherend such as a product. For example, it is provided with a label pressing means, provided with a turning means that can turn from the affixing position on one side of the label adherend to the affixing position on the other side of the adherend, and the label adherend on the front side and the left side by one unit. A label affixing device (see Patent Document 1) that can affix a label, a guide rail is provided so as to surround the periphery of the label adherend, a label pressing means is provided, and an advance / retreat mechanism that moves within the guide rail is provided. A label affixing device (see Patent Document 2) that can affix a label to the left side surface, right side surface, and upper and lower surfaces of a label adherend on a table is disclosed.

  However, the label affixing devices described in Patent Documents 1 and 2 are complicated, large in size, and expensive. For this reason, it has been difficult to introduce such a labeling apparatus for products with a small production quantity.

  Also, when sticking labels on various sticking surfaces such as the top surface, side surface, and bottom surface of an adherend such as a product with a single label sticking device, the warping of the label due to gravity is particularly significant in the case of top surface bonding and bottom surface bonding. Due to the effect, a slight deviation is likely to occur in the application timing. Due to such subtle timing shifts on the adherend that is transported at high speed on the belt conveyor, the label sticking position is greatly shifted, and the label feed timing to the adherend is adjusted each time the adherend is changed. There was also a problem that had to be done.

Therefore, the present invention can be applied to any surface such as the upper surface, side surface, and lower surface of the adherend with simple operation regardless of the size and shape of the adherend, and the arrangement space. An object of the present invention is to provide a label sticking apparatus that can save space and cost.

The present invention has been made in view of such circumstances,

The guide unit is rotatably supported by the lifting device with an axis parallel to the conveying direction of the commodity conveying means, and is configured to be locked at a predetermined angle. Thus, the above object is achieved.

  Further, the turret worm is rotatably supported by arranging a handle shaft having a worm gear attached to one end and the handle portion attached to the other end, and a turret worm having one end of the guide portion fixed coaxially. In addition, the above-described object is achieved by the label sticking device having a mechanism in which the guide portion for fixing the label driving portion can be rotated 180 degrees with respect to the vertical direction by the gear mechanism engaged with the worm gear.

  Since the embodiment of the present invention is configured as described above and the label feeding portion can be rotated 180 degrees with respect to the vertical direction, even if the shape of an adherend such as a product is a flat surface or a curved surface, In addition, the label can be supplied in parallel to the adherend surface of the adherend with a simple operation, regardless of whether the adherend surface of the product is the upper surface, side surface, or lower surface. Is possible. And since it can respond to such various label affixing operations with a single label affixing device, it is possible to provide a label affixing device that can save the arrangement space and reduce the cost.
