Description

[Detailed description of the invention] (1) The present invention relates to an improvement of a label pasting device for bottles.

(2) Problems that the invention aims to solve When manufacturing bottled products, it usually involves the work of pasting a label on the bottle after filling it with contents and closing the lid.
When applying a label to a part of a rectangular bottle, for example, only to the front side, the label applying apparatus does not require much ingenuity.
For example, when attaching a label only to the front of the body of a bottle, the label with adhesive applied to the back side is temporarily attached to the required location on the body of the bottle using a label feeder, and the belt conveyor that moves the bottle is required. The label can be easily attached to the front surface of the bottle by providing a roller or the like that presses the front surface of the bottle body to which the label is temporarily attached.

However, if a label is to be wrapped around the entire circumference of the bottle and applied, automating the process would require complicated equipment. If the bottle is cylindrical in shape and the label is attached to the body, it is not difficult to do so by using a device that smoothly rotates the entire bottle. However, when attempting to automate the process of attaching a label all around the neck of a bottle with a square body shape and a cylindrical neck, conventionally extremely complicated equipment was required. Unless a very large quantity of products is to be produced, it is actually difficult to mechanize such work due to the cost required for the equipment.

The purpose of this invention is to use a relatively simple device to
Particularly, the object of the present invention is to provide a device for automatically pasting a label all around the cylindrical neck of a square bottle.

(3) Means for Solving the Problems The present invention, which was made to achieve the above object, is based on a bottle with a rectangular body that passes as a conveyor belt moves, as shown in Figure 1. In an apparatus for pasting labels around the neck, a primary label pressing unit 1 comprises a pair of sponge rollers 3 that press the neck of the bottle as it passes along the first surface of the body; A primary guide 2 that guides the bottle that has passed through the primary label pressing part in a posture with the first surface facing downward; A star wheel 4 is provided for turning the bottle so that a second side next to the first side of the body is on the lower side; a secondary guide 5 that guides the bottle with the second side facing down; a secondary label pressing unit 6 that presses the neck of the bottle while the bottle is moving with the second side facing down; Next, a turning protrusion 7 provided on the guide 5 changes the direction of the bottle so that a third surface further adjacent to the second surface of the body becomes the lower side; A label sticking device characterized by having a tertiary label pressing section 8 for further pressing the neck.

(4) Effect In the labeling device having the above structure, when a bottle whose neck has already been temporarily pasted with a label coated with adhesive on the back side by the label feeder, as the conveyor belt moves, the neck of the bottle first becomes attached to the pair of labels. sponge·
It passes through a primary label pressing section 1 consisting of a roller 3. Here, the central part of the label is affixed to the neck, and in particular the proximal end of the label is completely affixed to the neck of the bottle, but the tip is still hardly affixed.
The bottle that has left the primary label press 1 follows the flow of the conveyor belt along the primary guide 2 and hits the star wheel 4, its orientation is significantly reversed and it moves along the secondary guide 5, its neck being The bottle is pressed again by the secondary label pressing section 6, but at that time, the direction of the bottle has already been turned by the star wheel 4, so the tip of the label that could not be pressed by the primary label pressing section 1 Most of the parts are pasted. Furthermore, while the bottle is moving along the secondary guide 5 according to the flow of the conveyor belt, it hits the turning protrusion 7 and further changes its direction, and then the neck is moved by the tertiary label pressing part 8. It is further pressed down, and the remaining unattached portion of the tip of the label is also affixed to the neck of the bottle, and the label is affixed to the entire circumference of the neck.

(5) Embodiments Hereinafter, embodiments of the present invention shown in the drawings will be described in detail. FIG. 1 is a plan view of the present invention, and FIG. 2 is a front view of the secondary label pressing section. Note that in FIG. 1, arrows indicate the flow direction of the conveyor belt.

According to the present invention, the bottle 10 to which a label is to be attached to the neck 11 is temporarily attached to the neck 11 by a label feeder at the top of the conveyor belt 9, with the label 12 having its back surface coated with adhesive. In this state, we approach the device according to the present invention. In this case, a portion of the base end 13 and most of the distal end 14 of the label 12 are not yet attached to the neck 11 at all (bottle 10-A).

The primary label pressing unit 1 includes a pair of sponge rollers 3 arranged at the height of the neck 11 of the bottle 10.
The sponge roller 3 is given a force directed upward of the conveyor belt 9 by a tension spring 15. The bottle 10 carried by the conveyor belt 9 passes between the pair of sponge rollers 3 while pushing them apart left and right against the force of the tension spring 15, and the label 12 that has been temporarily pasted on the bottle 10 passes between them. A considerable portion is pressed and adhered to the neck 11 by the sponge roller 3. In particular, the proximal end 13 with a slight unattached portion remaining is completely attached to the neck 11 of the bottle 10. However, the tip 14 of the label 12 is not yet attached (bottle 10-B).

Further along the primary guide 2 a conveyor belt 9
The bottle 10 carried by the conveyor belt 9 leaves the tip of the primary guide 2 and hits the star wheel 4, and the force carried by the conveyor belt 9 rotates the star wheel 4 by one frame, and the bottle 10 itself is further turned in a certain direction. (Bottle 10-C).

The bottle 10 that has come out of the frame of the star wheel 4 passes through a secondary label pressing section 6 while moving along the secondary guide 5. The main part of the secondary label pressing section 6 is pivotally attached to the shaft arm 20, has a sponge-like cushioning material 16 on the pressing surface, and has a tension spring 17 that applies upward force to the conveyor belt 9. The pressing member 18 is provided with a pressing member 18.
The tip of is arranged at a position that corresponds to the neck portion 11. Bottle 10 inserted into secondary label pressing section 6
The neck 11 hits the pressing member 18 and is moved by the conveyor belt while pushing the pressing member 18 against the force of the tension spring 17, but the neck 11 is held by the pressing member 18 until it comes off the tip of the pressing member 18. (Bottle 10-D). At this time, since the direction of the bottle 10 has already been turned by the star wheel 4, most of the tip 14 of the label 12, which could not be pressed by the primary label pressing section 1, is pressed against the neck 11 by the pressing member 18. It is pressed against the surface and pasted, but the most advanced part is still left unpasted.

Furthermore, the bottle 10 moves along the secondary guide 5 and hits a turning protrusion 7 provided in the middle, further changing the direction by 90 degrees.
It turns once (bottle 10-E) and passes through the tertiary label pressing section 8 provided at the end (bottle 10-F). The structure of the tertiary label pressing part 8 is the same as that of the secondary label pressing part 6, and the main part is pivotally attached to the shaft arm 25, has a sponge-like cushioning material 21 on the pressing surface, and has a tension spring 22. A pressing member 2 is applied with a force directed upward of the conveyor belt 9 by
3, and the tip of the pressing member 23 is arranged at a position that hits the neck 11. Here too, bottle 1
0 passes through the secondary label pressing part 6, the neck part 11 hits the pressing member 23, moves while pushing the pressing member 23 against the force of the tension spring 22, and the neck part 11 hits the pressing member 23. The neck 11 is pressed by the pressing member 23 until it is released from the tip, but at this time, the bottle 10 is further turned 90 degrees by the turning protrusion 7, so the second label pressing part 6 Label 12 that I couldn't hold down
The leading edge of the label is completely adhered, thus completing the labeling operation. (Bottle 10-G).

In addition, each member constituting this device, that is, the primary to
The position, angle, and height of the tertiary label pressing parts 1, 6, 8, the primary and secondary guides 2, 5, and the star wheel 4 relative to the belt conveyor 9 can be arbitrarily and easily changed. Therefore, when working with bottles of different sizes,
The position of each member relative to the belt conveyor 9 is adjusted to achieve the objective.

(5) Effects of the invention As described above, according to the invention, a label can be automatically affixed to the entire circumference of the cylindrical neck of a particularly square bottle. In addition, since this label sticking device can be constructed by simply combining conventional label pressing means and guide means, the structure is simple and can be manufactured at low cost. - The position, angle, and position relative to the conveyor can be arbitrarily and easily changed, so when working with bottles of different sizes, you can adjust the position of each member without replacing the entire device. Label pasting work is possible.
