Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating device for shielding scratches that occur on the bodies of glass bottles, such as beer bottles or bottles for carbonated drinks such as cider and cola.

Conventionally, as a method for shielding this kind of glass bottle from scratches, the author of this paper published Japanese Patent Publication No. 56-62371 (Japanese Unexamined Patent Publication No. 56-62371). Since the coating is applied to the scratched portions of bottles by dipping or dipping, it is difficult to quickly and efficiently apply the coating to a large number of scratched bottles.

This invention was made in view of the above-mentioned conventional situation, and its purpose is to improve the work efficiency by quickly and efficiently coating a large number of worn bottles. Our goal is to provide the following.

The present invention will be described with reference to embodiments shown in the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a conveyance path for bottles 2. On one side of this conveyance path 1, a rotary disk 4 whose center is attached to a drive shaft 3 is disposed with its peripheral edge close to the conveyance path 1. ing.

Reference numerals 5 and 6 indicate entrance/exit star wheels disposed across the rotary disk 4 and the conveyance path 1, and 7 and 8 are disposed outside the star wheels 5 and 6 at intervals such that the body 2a of the bottle 2 can pass therethrough. This star wheel 5 is formed by a guide frame equipped with an elastic friction material 9 such as a sponge on the part that faces and contacts the body 2a.
, 6 and the guide frames 7 and 8, the bottles 2 sent on the conveyance path 1 are supplied onto the rotary disk 4, and the bottles 2 are discharged from the rotary disk 4 onto the conveyance path 1 again. ing.

A plurality of through holes 1 are provided along the circumferential direction on the periphery of the rotary disk 4.
0 are bored at equal intervals, a pulley 11 is attached to the lower part of the through hole 10, and a bottle holder 12 is rotatably supported on the rotary disk 4. A bottle crossing plate 13 is fixed between each pedestal 12 on the rotary disk 4, and this plate 1
3 and the surfaces of the pedestal 12 are substantially on the same horizontal plane as the conveyance path 1. Gears 17 and 18 that mesh with the gear 16 attached to the drive shaft 3 are attached to the shafts 14 and 15 of the star wheels 5 and 6, so that the rotation of the star wheels 5 and 6 is linked to the rotation of the rotary plate 4. It's getting old. Wheel axis 14
, 15 have pulleys 9 and 20, and a pulley 23 is mounted on a shaft 22 which is installed upright on a machine frame 21 on the opposite side of the rotary disk 4 from the star wheels 5 and 6 and adjacent to the rotary disk. It is installed at the same height as the pulley 11 on the stand 12, and a part of the pulley 11 is installed between the pulleys 19, 20 and the pulley 23.
A V-belt 24 is wound around the V-belt 24 so as to make contact with the V-belt 24.
When the belt 24 rotates, the pedestal 12 of the pulley 11 that comes into contact with the belt 24 rotates relative to the rotary disk 4. A coating roller 28 is rotatably supported on the drive shaft 3 on the rotary disk 4 via a bearing 27, and is eccentric to the opposite side of the star wheels 5, 6 by a desired amount e with respect to the center of the shaft 3. The coating roller 28 has a coating portion 2 with sponge lining on the upper and lower peripheral surfaces.
8a, and a pulley 29 is attached to the upper part. The tip of an arm 31 supported by a support 30 in a direction perpendicular to the conveyance path 1 is also detachably attached to the coating roller 28, so that the eccentricity e can be adjusted as appropriate!
I am doing it. Rotating shafts 34 and 35 are supported on the arm 31 via bearings 32 and 33, and intermediate rollers 3 made of stainless steel are mounted on the rotating shafts 34 and 35, and are in rotatable contact with each other.
6 and a sponge-lined supply roller 37 are disposed with the intermediate roller 36 in rotatable contact with the coating roller 28. The supply roller 37 is pumped up from a tank (not shown) to a nozzle (not shown).
A coating liquid is supplied to the intermediate roller 36, which is further transferred to an intermediate roller 36 to form a uniform thin film, and then sent to a coating portion 28a of a coating roller 28. Supply roller 37
A tray (not shown) is provided at the bottom of the tank to receive excess coating liquid, and when it is accumulated, it is circulated back to the tank.

The coating liquid is preferably an emulsified dispersion liquid containing dimethyl silicone as a main dispersion component, such as sorbitan fatty acid esters or glycerin monoesters. Further, two pulleys 38 and 42 are attached to the rotating shaft 35 on the upper and lower sides, and a V-belt 39 is wound around the pulley 38 and the pulley 29 of the coating roller 28. A V-belt 43 is wound around a pulley attached to the shaft. 40,4
Reference numeral 1 denotes gears attached to the rotating shafts 34 and 35 in mesh with each other, and 44 an arm branch attached to the arm 31. The guide frames 7 and 8 are held by the arm branch 44.

On the other hand, the upper part of the drive shaft 3 has a similar size to the rotary disk 4.
A rotary disk 48 having the same number of support bosses 47 as the pedestals 12 is attached to a peripheral portion facing the pedestals 12 . An elevating rod 50 having a holding head 49 at its lower end is supported by the boss portion 47, and the head 49 holds the upper part of the bottle 2, whose lower part is held by the pedestal 12, so that the bottle 2 can rotate. I'm starting to do that. The holding head 49 is connected to the lifting rod 50 via a spring 51 and a thrust bearing 52. A cam roller 55 is installed inside the upper part of the lifting rod 50, and a spring 5 is installed between the roller installation part and the boss part 47.
6 is attached to constantly urge the holding head 49 upward. A cam portion 57 of a cam member 58 supported by the drive shaft 3 is engaged with the cam roller 55, and the cam portion 56 rotates the bottle 2 on the pedestal 12 from the inlet star wheel 5 to the outlet star wheel 6. During movement, the lifting rod 50 is pushed down against the spring 56. The cam member 58 is fixed to an arm 60 supported by a column 59. Furthermore, in FIG.
A drying section A and a finishing section C are provided before and after the rotational direction of the coating section B where the body section 2a of the bottle 2 held by the bottle 2 is coated by sliding contact with the coating section 28a of the coating roller 28. There is a supply pipe 61 in the drying section A.
A plurality of air nozzles 62 are arranged to inject air toward the body 2a of the empty bottle 2, and in the finishing section C, a wiping belt 63 made of cotton cloth or the like is in contact with the bottle body 2a on the pedestal 12. It is arranged so that it can rotate.

Next, the operation of the above embodiment will be explained.

When the drive shaft 3 is rotated by a motor (not shown), the rotary disks 4, 48 and the star wheels 5, 6 are rotated in forward and reverse directions, respectively.

Also, due to the rotation of the star wheels 5 and 6, the pulleys 19 and 20 and the pulley 23 attached to the wheel shafts 14 and 15 are rotated.
The V-belt 24 wrapped around the belt also rotates, and is thereby sequentially moved together with the rotary plate 4 to the drying section A and the finishing section C.
a pedestal 1 that is located at and comes into contact with the belt 24;
2 is rotated. On the other hand, when the rotating shaft 35 of the supply roller 37 is rotated by the motor connected via the belt 43, the intermediate roller 36 is rotated in the opposite direction to the supply roller 37 via the gears 40 and 41, and the coating roller 2
8 is rotated in the same direction as the rotary disk 4 via a V-belt 39.

The bottles 2 washed with water and sent by the conveyor 1'' through the conveyance path 1 in the above process are separated from each other by a certain distance by an inlet star wheel 5 and a guide frame 7, as shown in FIG. The bottle body 2a is guided through the plate 13 over the bottle holder 12 of the turntable 4, and the bottle body 2a is moved by the rotating wheel 5 between each tooth 5'' of said wheel 5 in its recess 5'' and in the elastic It contacts the friction material 9 and is moved while rotating.

Thereafter, the elevating rod 50 is pushed down by the cam part 57, and the head 49 holds the upper part of the bottle 2, so that the upper and lower parts of the bottle 2 are completely held by the head 49 and the pedestal 12. Next, when the bottle 2 held as described above advances to the drying section A, the pulley 11 of the pedestal 12 moves to
Since the bottle 2 comes into contact with the belt 24, it rotates several times, and during this period, air is jetted from the nozzle 62 toward the body 2a, drying the surface of the body 2a.

Next, when the bottle 2 advances to the coating section B, the body section 2a comes into sliding contact with the coating section 2δa of the coating roller 28, and from the coating section 28a, the nozzle and the supply roller 37
The coating liquid supplied to the coating roller 28 via the intermediate roller 36 is applied to the scratches generated on the upper and lower parts of the body 2a.

Since the bottle 2 rotates on its own axis due to frictional contact with the coating roller 28, this coating is done evenly over the entire circumference. Furthermore, if uneven coating occurs during coating, it can be adjusted by changing the attachment position of the tip of the arm 31 to the coating roller 28 and adjusting the amount of eccentricity e. When the bottle 2 further advances to the finishing section C, the pulley 11 of the pedestal 12 comes into contact with the belt 24, so the bottle 2 rotates several times, and during this time, the bottle 2 rotates in the opposite direction to the rotation direction. The surface of the body portion 2a is wiped off by the cleaning belt. After being wiped off, the bottles 2 are transferred from the pedestal 12 of the rotary disk 4 to the conveyance path 1 via the crossing plate 13 by the outlet star wheel 6 and the guide frame 8, with the bottles 2 being spaced at the required intervals in the same manner as described above. are separated and discharged.

This is to continuously coat and shield the scratches that occur on the bodies 2a of the large amount of bottles that are fed on the conveyor 1 as described above.

In the above embodiment, the rotary disk 4 was arranged on one side of the conveyance path 1, but it is not necessarily necessary to have such a structure. It may also be provided with a supply and discharge section. Furthermore, although the coating liquid is supplied to the coating roller 28 from a nozzle via the supply roller 37 and the intermediate roller 36, it may be configured to directly supply the coating liquid to the coating roller 28. design changes are possible. Since this invention is configured as described above,
It is possible to quickly and efficiently apply the coating to a large number of scratched bottles, it can reliably cover scratches that occur on the body of the bottle, and it does not require any human intervention at all.
It has excellent effects such as significantly increasing work efficiency compared to conventional methods.
