Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a label sticking device suitable for sticking a band-shaped label to a container such as shampoo or cosmetics.

[0002]

[Prior Art]

 Generally, in a factory for manufacturing shampoo for washing hair, for example, as shown in FIG. 9, after filling a bottle 1 as a container made of a plastic material or the like with a shampoo liquid through a filling port (not shown), The filling port is covered with the cap 2. Then, by using the labeling device, a belt-shaped label (sealing sticker) 3 such as a catch copy label for differentiating from other companies' products and increasing the willingness to purchase is attached from the upper end surface 2A side of the cap 2 to the shoulder of the bottle 1. It is attached to the part 1A side and shipped.

Here, the label sticking device is provided with a carrier device including a star wheel, and a belt-shaped label 3 that is provided in the middle of the carrier of the carrier device and is continuously supplied by using a negative pressure. Then, an attachment device that attaches the center side of the label 3 to the upper end surface 2A of the cap 2, and a delivery device that is located on the downstream side of the attachment device and is provided in the middle of the delivery of the delivery device and has a predetermined interval. The pressure-bonding device is composed of a pair of rollers that are spaced apart in the longitudinal direction and that can be moved up and down.

The label sticking apparatus according to the prior art has the above-described structure. First, when an operator arranges the bottle 1 with the cap 2 attached on the carrying apparatus in an upright state, the bottle 1 is transferred. It is conveyed to the attachment position sequentially by the device. Then, the attachment device attaches the label 3 so that the central portion thereof is located on the upper end surface 2A of the cap 2 and temporarily fixes it. Next, the bottle 1 with the label 3 attached to the upper end surface 2A of the cap 2 is again transported to the downstream side by the transport device and is placed at the crimping position. Then, the crimping device attaches the label 3 to the bottle 1 by moving both rollers downward and pressing both ends of the label 3 toward the shoulder 1A side of the bottle 1 by the rollers. wear.

[0005]

[Problems to be solved by the device]

 By the way, in the above-described conventional label sticking apparatus, the label 3 is stuck to the upper end surface 2A of the cap 2 by the sticking apparatus, temporarily fixed by the adhesive on the back surface of the label 3, and then the label is stuck by the crimping apparatus on the downstream side. 3 is attached to bottle 1. However, in the attachment device, since the central part of the label 3 is only temporarily fixed to the upper end surface 2A of the cap 2, both ends of the label 3 are unstable, and the label is conveyed from the attachment device to the pressure bonding device in the next step. If the label 3 is subjected to vibrations or shocks during transportation, or if it is exposed to air from an air conditioner or the like while the label 3 is being held, the label 3 is likely to be slanted or twisted from its original attachment position.

Therefore, when the label 3 is pressed by each roller of the pressure bonding device, not only sticking defects such as wrinkles occur on the label 3, but also the label 3 is peeled off from the upper end surface 2 A of the cap 2. There is a problem that the product value and the yield are significantly reduced because the bottle 1 to which the label 3 is not attached is manufactured. In particular, shampoos, cosmetics, and the like are also image products, so if these bottles 1 that are not properly attached are shipped, market complaints are likely to occur, and there is a problem that credit will be significantly reduced.

The present invention has been made in view of the above-mentioned problems of the prior art. When a label is attached to a container, the label is prevented from causing a sticking defect such as a shift or a twist, and the label is attached accurately. It is an object of the present invention to provide a labeling device that can be used.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the structure adopted by the present invention is a conveyor for conveying a container filled with contents and covered with a cap from one side to the other side in a rollover state, and the conveyor. A label supply unit which is provided above the conveyor and is provided in the middle of conveyance of the label and supplies the strip-shaped label attached to the mount from the upper side to the lower side, and the front side of the mount supplied by the label supply unit. A frame which is provided so as to be movable up and down adjacent to the position and has leg portions on the left and right sides, a pair of rods which are rotatably provided on each leg portion of the frame, and a lower end side of each rod.
