DETAILED DESCRIPTION OF THE INVENTION This invention relates to a scratch coating device for glass bottles such as beer bottles.

[Direct]ヱ目L4 Conventionally, as a device of this type, the one described in Japanese Patent Publication No. 5545.5/1987 proposed by the present applicant is known.

However, in this known coating device, the coating liquid is supplied from the inside in the direction of conveyance of the beer bottle, which is conveyed from the bottle supply section to the bottle discharge section on a rotary disk. Only one section can be provided. Therefore, it is not possible to supply a large amount of the coating liquid, and it is difficult to say that the desired area of the body of the beer bottle is always sufficiently coated, resulting in uneven coating.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a coating device that can supply just enough coating liquid and prevent uneven coating.

In order to achieve the above object, the coating device of the present invention includes a glass bottle transfer path provided with a bottle supply section on one side in the circumferential direction and a bottle discharge section on the other side, A star wheel that is rotatably installed on the road and receives the body of a crow bottle supplied from the bottle supply section into a recess formed between its teeth to maintain the distance between the bottles, and also transports the iron kettle by rotation. a rotating roller provided at the tip of each tooth and a concave portion of the star wheel so as to be able to come into contact with the body of the glass bottle; a driving member for rotating the star wheel; and a rotating roller provided on the outer periphery of the glass bottle transfer path. and a guide plate having an elastic body on the inner surface with which the body of the glass bottle sent by the rotation of the star wheel slides, and a plurality of notches provided at predetermined intervals in this guide plate to the outer periphery toward the glass bottle transfer path side. an elastic coating roller that is rotatably supported vertically with a part of the roller protruding, and that applies a coating liquid to the body of the glass bottle that rotates by slidingly contacting the elastic body during transportation; and these coating rollers. The roller has a nozzle in sliding contact with the outer circumferential surface of the roller that does not protrude from the notch, and a coating liquid supply member that supplies the coating liquid from the nozzle to the coating roller.

In the above, a plurality of nozzles may be provided at predetermined intervals in the axial direction of the coating roller, and a valve may be provided to each of these nozzles to adjust the coating liquid supplied thereto.

■---Glass bottles are fed from the bottle supply section along the glass bottle transfer path without being kept at a distance by the rotation of the star wheel.
It is sent without being rotated (rotated) by sliding contact between the rotating roller provided on the star wheel and the elastic body of the guide plate. When you reach the position of the coating roller,
Since the body of the bottle does not rotate, it is rotated by pressing the roller, and during this rotation, the coating liquid is applied from the coating roller to the surface of the body. Then, at the position of the coating roller where multiple applications are made,
This is done around the entire circumference of the bottle as it rotates, thereby covering up any scratches on the body surface. The glass bottle that has been coated is discharged to the bottle discharge section.

As described above, since the coating liquid is supplied from a plurality of locations from the outside in the direction of conveyance to the glass bottle being sent on the glass bottle transfer path, it is possible to supply just the right amount of coating liquid.

．． The beer bottles 13 are received in the recesses formed between the teeth of the beer bottles 10, and the beer bottles 13 that are placed on the plate base 5 and sent without being kept at a distance from each other are formed to form a transfer path that stands up in a line and continuously transfers them. There is.

The plate stand 5 is rotated by a cam mechanism (not shown) during one rotation of the rotary disk 7, and this rotation causes the bottle 13 that rests on the upper surface of the plate table 5 and whose mouth is held by a gripper to be rotated by a cam mechanism (not shown). is rotated, and a label is attached to the body portion 13a.

Reference numeral 14 denotes a rotating roller provided at the tip of each tooth of the star wheel 9 and in the recess, with which the body 13a of the beer bottle 13 comes into contact when received in the recess.

Reference numeral 15 denotes an arcuate guide plate, which is provided on the outer periphery of the transition plate 8 from the labeler main body side to a position near the exit roaster wheel 1O at a height sufficient to cover the body 13a of the beer bottle 13.

An elastic body 16 made of sponge or the like is provided on the inner surface of the guide plate 15, and the body 13a of the beer bottle 13 to be transferred slides thereon. In addition, as shown in FIGS. 2 and 3, a plurality of (four in this embodiment) notches 17 are provided at predetermined intervals in the length direction of the guide plate 15, and the transition plate 8 extends from these notches. A coating roller 18 made of an elastic material such as a sponge with a part of its outer circumference protruding toward the side is attached to the bearing 2.

On the outer circumferential surface of the coating roller 18 that does not protrude from the notch 17 toward the crossing plate 8 side, a plurality of coating liquid supply nozzles 22 (five in this embodiment) are spaced at predetermined intervals in the axial direction and slide through their tip openings. The rear end openings of these nozzles 22 are arranged sideways in contact with each other, and the rear end openings of these nozzles 22 are collectively connected to a single pipe 23, and a supply pipe 25 is connected to a coating liquid supply member (not shown) via a T-shaped joint 24. connected to. A regulating valve 26 is provided near the opening at the tip of the nozzle 22 so that the amount of coating liquid supplied from the nozzle 22 can be adjusted. 1st
In the figure, 28 is a support member that supports the supply pipe 25 and is attached to the kite board 15.

As the coating liquid applied to the bottle in the above, there is, for example, a scratch shielding agent mainly composed of silicone resin disclosed in Japanese Patent Laid-Open No. 61-6152.

Next, the operation of the embodiment will be explained.

When a driving member (not shown) is driven, the inlet conveyor 1, the inlet star wheel 3, the rotary disk 7 of the labeler main body 6, the coating device star wheel 9, and the output rotor wheel 1O1 and the output conveyor 11 rotate and stand up from the inlet conveyor l. The beer bottles 13 that are sent are kept at a distance by the concave part of the inlet star wheel 3, are sent over the transition plate 2, and are transferred onto the plate stand 5 provided on the rotary disk 7 of the labeler main body 6.

The beer bottle 13 transferred onto the plate stand 5 is fed one round by the rotation of the rotary disk 7, during which time it is rotated on its own axis as described above, and a label is attached to the bottle body. and,
The printing plate 5 is transferred onto the transfer plate 8 of the coating device. The beer bottles 13 transferred onto the crossing plate 8 are transferred on the plate 8 by the rotation of the star wheel 9 while being kept at a distance by the concave portion of the wheel. It slides on the rotating roller 14 and the elastic body 16 of the guide plate 15 and rotates (rotates) as shown in FIG. The beer bottle 13 thus rotated and transferred on the plate 8 first comes to a position where the first coating roller 18 is located. Here, as shown in FIG. 2, the upper part 173 of the body 13a of the bottle is still in sliding contact with the uncut portion of the elastic body 16 of the guide plate 15, so the rotation (autorotation) is maintained and the bottle is The body 13a presses the coating roller 18, and this pressure causes the coating liquid supplied from the nozzle 22 to be applied to the surface of the body 13a.

The coating liquid is not only applied by sliding the body 13a onto the elastic body 16 at the position of a plurality of coating rollers 18, but also applied to the elastic body through a bottle to which the coating liquid has already been applied. 16 (the part where there is no coating roller 18) is also transferred and stretched, and the non-notched parts are also applied by sliding contact with the elastic body 16, so that the coating is carried out evenly over the entire circumference, Scratches on the surface of the body portion 13a are covered. Along with this application, the coating roller 18 is rotated in the opposite direction, and the coating liquid is supplied from the nozzle 22 to the area where the coating liquid has decreased due to the application.

Furthermore, if there is a part of the body 13a of the bottle where the coating liquid should be applied for a particularly long time during the application, the amount of supply is adjusted using the regulating valve 26 provided in the nozzle 22 near the part.

The bottles 13 coated with the coating liquid are then kept at a distance from the star wheel 9 by the rotation of the outlet star wheel 10 in the concave portion of the wheel, and then transferred from the transfer plate 8 to the outlet conveyor II, where they are transferred from the transfer plate 8 to the outlet conveyor II. Sent to subsequent process.

As mentioned above, the body 13 of the beer bottle 13 immediately after laher is pasted.
The coating liquid is supplied to a from the outside in the direction of transport by a plurality of coating rollers 18. In this embodiment, the coating roller 18 is rotated by the rotation of the bottle I3 being transferred. The coating roller may be forcibly rotated using a V-belt connecting the coating roller, a drive motor, or the like.

In addition, the embodiment merely shows a preferable example, and the detailed design can be changed in various ways without changing the gist.

The invention of claim 1 has the above-mentioned configuration, and is a system in which the coating liquid is supplied from a plurality of locations on the outside of the glass bottle being transferred in the direction of transfer, so that it is possible to supply the coating liquid to the glass bottle in just the right amount. can. Therefore, coating unevenness is completely eliminated.

According to the second aspect of the present invention, when supplying the coating liquid to the coating roller, it is possible to supply the coating liquid only to an arbitrary part of the body of the glass bottle, and the amount of the coating liquid to be supplied can also be arbitrarily adjusted using a valve.
