Description

  The present invention relates to a label sticking device for sticking a label having an adhesive layer on one side to a container, and in particular, a container transport device for transporting a container to a label sticking position and an adhesive layer on one side. A label transporting device that transports the label on the side opposite to the pressure-sensitive adhesive layer on which the label is attached to the container and that guides the label to the label application position, and a label supply device that supplies the label to the label transporting device. In the label applicator, the label applicator can transport the labels to the label applicator sequentially so that the label can be applied to the container efficiently without increasing the size of the label applicator, and the label transport device is transported by the container transport device. Even when the number of containers to be changed fluctuates, it is characterized in that the label can be appropriately applied to the container stably.

  Conventionally, various label applicators have been used to attach a label having an adhesive layer on one side to a container.

  In recent years, a heat-sensitive adhesive is used for the pressure-sensitive adhesive layer of the label, and after printing on the surface of the label opposite to the pressure-sensitive adhesive layer, the surface of the label on which the pressure-sensitive adhesive layer is formed is heated. There is also used a label sticking device that imparts viscosity to the heat-sensitive adhesive used in the pressure-sensitive adhesive layer and attaches the label having the viscosity to the pressure-sensitive adhesive layer to the container.

  In recent years, a drum-type label applicator as shown in Patent Document 1 has been proposed as a label applicator for sequentially attaching labels using heat-sensitive adhesive to the adhesive layer in this manner. ing.

  Here, in the label sticking apparatus shown in Patent Document 1, a continuous label body in which a pressure-sensitive adhesive layer is provided on one side of a long label substrate is cut into individual labels by a cutter. At the same time, a drum having a plurality of suction holes with a plurality of suction holes for sucking and holding the surface opposite to the adhesive layer of the cut label is provided at equal intervals on the peripheral surface, and this drum is rotated. Every other label cut at the label supply position is held by the label holding portion of the drum.

  Then, with the label held in every other label holding part provided on the drum in this manner, the pressure-sensitive adhesive layer of the label held by the heating device provided around the drum is heated, and the pressure-sensitive adhesive layer When the heat-sensitive adhesive in the adhesive layer is given viscosity, and the label with viscosity applied to the adhesive layer is returned to the label supply position, it passes without supplying the label to the label holding section. The label is attached to the container and guided to the label attaching position, and the container is guided to the label attaching position in synchronization with the label, the label is attached to the container, and the above operation is repeated. The labels are attached in order.

However, in the case where every other label is held in the label holding part of the drum and stuck to the container in this way, the efficiency of sticking the label to the container becomes very poor, and many labels are attached to the label holding part of the drum. In order to hold it, it is necessary to use a drum having a very large diameter, which causes a problem that the apparatus becomes large. In addition, when the number of containers guided to the label application position fluctuates, there are various problems such as an operation that appropriately controls the timing of holding the label on the label holding portion of the drum. .

  An object of the present invention is to solve various problems as described above in a label sticking apparatus for sticking a label having an adhesive layer on one side to a container.

  In this device, a container transporting device that transports a container and guides it to a label application position, and a label with an adhesive layer provided on one side is transported in a state where the surface opposite to the adhesive layer is sucked and held. In a label sticking device provided with a label transport device that leads to a position and a label supply device that supplies a label to the label transport device, in particular, when a label using a heat-sensitive adhesive is applied to a container, the label Without increasing the size of the affixing device, the labels can be transported sequentially to the label affixing position by the label transporter so that labels can be applied to containers efficiently, and the number of containers transported by the container transporter varies. Even in such a case, it is an object to enable a label to be properly and stably attached to a container.

  In this device, in order to solve the above-described problems, a container transport device that transports a container and leads it to a label sticking position, and a label provided with an adhesive layer on one side of a label substrate are opposite to the adhesive layer. In a label sticking device comprising a label transport device that transports in a state where the side surface is sucked and held and leads to a label sticking position, and a label supply device that supplies a label to the label transport device, the label transport device described above, An endless belt-shaped label holding member with a plurality of suction holes, which is driven to rotate, and the surface opposite to the adhesive layer of the label are sucked through the suction holes to suck and hold the label on the label holding member. When the first sensor and the second sensor are provided at a predetermined distance at a position where the container is transported by the container transport device and guided to the label attaching position. A stopping device for stopping the container conveyed to the labeling position by the container conveying device, and stopping the container by the stopping device when the container is detected by the first sensor and the second sensor. A controller is provided that releases the container to the label application position and supplies the label to the label transport apparatus by the label supply device to guide the label to the label application position.

  Here, when a heat-sensitive adhesive is used for the pressure-sensitive adhesive layer in the above-mentioned label, the label is transported to the portion where the label is guided to the label application position by the above-mentioned label transport device so as to face the pressure-sensitive adhesive layer of the label to be transported. A heating device for heating the heat-sensitive adhesive is provided.

  Moreover, when using the elongate label continuous body by which the adhesive layer was provided in the single side | surface of the elongate label base material, a label continuous body is guide | induced to said label conveyance apparatus to said label supply apparatus.
