Description

Painting device for barcode base {Painting device for barcode base}

The present invention is a painting apparatus for painting the base of the bar code indicating the specifications of the article on the surface of the article or wrapping paper, and more particularly, to improve the removal means of the paint applied to the mask, preventing clogging of the injection port and cleaning means of the injection port By doing so, the workability is more improved, and relates to a painting device for a barcode base that prevents environmental pollution.

Currently, it is common to display a bar code indicating the specifications of a product on the surface of an article or a package. As a method of displaying the bar code, a label on a product package is printed by a printing method or a bar code printed label is attached to the article or a package. Doing.

However, some special parts of the conventional bar code representation method as described above, that is, the bar code display method of the brown tube, can be printed by the conventional bar code printing method due to various factors such as the washing process and the high temperature and high temperature furnace. As it is impossible to do this, special printing of bar codes on ceramic tape has been used until now.

The ceramic bar code labels mentioned above are uneconomical problems, which are a factor of the cost increase because they depend on the total imports.

Therefore, according to the patent application 19049 by the applicant of the present invention, a plurality of masks having a printing hole are rotated by an endlessly rotating chain, and when the electric mask reaches a certain position, paint is automatically sprayed to the mask. Since the paint sprayed through the printer to be painted on the surface of the article, not only shortening the working time, but also the painting position is constant, the base painting paper for the bar code has been created to increase the productivity.

However, in the painting printing method as described above, since the cleaning of the paint sprayed mask is performed by a separate chemical agent (paint solvent such as thinner), the use of the paint is regulated, and the use thereof is regulated. If there is no spraying operation from the nozzle, the paint is solidified and the spraying nozzle is clogged, so there is a problem that the user has to clean the spraying nozzle one by one.

The present invention has been made to eliminate the problems as described above, by changing the cleaning means of the electric mask to the removal means by the brush, not the paint solvent, and the removal means by the brush is operated by the suspension drive means, The paint removal efficiency is improved, and when the supply of the product is stopped, the mask is transported a certain distance to spray on the part where the printing hole is not formed to prevent the blockage of the injection port, and the accumulated paint coagulated material to a separate cleaning means. It is an object of the present invention to provide a bar code base painting apparatus which can be removed by, thereby significantly reducing the defective rate while increasing its productivity.

Technical means for achieving the above object is that the electric brush drive means and the suspension device of the drive means and the drive means for varying the injection flow path and the cleaning flow path as the rotating shaft of the injection nozzle is rotated.

1 is a front explanatory view of the painting apparatus of the present invention, Figure 2 is a side cross-sectional view thereof.

A spray nozzle formed in the main body 1 to coincide with a mask 4, 4 'having an orbital chain 2 and a printing hole 3, and a printing hole 3 of the mask 4, 4'. In the conventional bar code base painting apparatus having a (5),

Brushes 7 and 7 'which are rotated by the vertical drive motors 6 and 6' are built in the main body 1, and the chain 2 and the mask between the electric brushes 7 and 7 '. (4) (4 ') is moved.

In addition, the spray nozzle 5 at the time of one-step movement of the endless track chain 2 with the scattering prevention duct 19 and the masks 4 and 4 'which prevents the paint from scattering when the spray nozzle 5 is sprayed. And a forward and backward movement cylinder 20 for moving back and forth the injection unit with the scattering prevention duct 19 attached thereto.

In addition, the up and down drive motors 6 and 6 'are guide plates inserted into the left and right support bars 8 and 8'.

(9) (9 ') is formed so as to be movable up and down, the handle is to be moved up and down by a separate spring (10) (10') and the rotation is symmetrical in the center of the electric guide plate (9) (9 ') (11) and (11 '), and in the normal operation of the painting apparatus, the center of the printing hole (3) of the mask (4) (4') and the spray nozzle (5) coincide, and the painting apparatus When the paint is not sprayed, in order to prevent the spray nozzle 5 from clogging, the masks 4 and 4 'are transferred at a predetermined distance so that the center of the spray nozzle 5 is separated from the printing hole 3. Intermittent injection operation is made toward 4 '.

Further, the rotary shaft 13 having the injection hole 12 is rotatably arranged at the tip of the injection nozzle 5, and connecting flow passages 14 and 14 'are formed on both sides of the injection nozzle 5, In normal operation, the spray nozzle 5 and the paint pump 15 and the paint container 16 are connected,

When the spray nozzle 5 is cleaned, a separate solvent pump 17 and a solvent container are rotated so that the spray hole 12 communicates with the connection passages 14 and 14 '. It is combined with (18).

Referring to the operation of the present invention by the above configuration in more detail by the accompanying drawings as follows.

As shown in FIGS. 2 to 3, the brushes 7 and 7 ′ spaced up and down are built up by the drive motors 6 and 6 ′ in the main body 1, and the chains are separated between the spaces. 2) and a plurality of masks 4 and 4 'are configured to rotate.

Therefore, while the chain 2 and the mask 4 and 4 'on the caterpillar are rotated, the drive motors 6 and 6' and the brushes 7 and 7 'installed thereon are rotated at high speed. The brush 7, 7 ′ rubs against both surfaces of the mask 4, 4 ′ and removes paint and foreign matter on the surface.

At this time, the drive motor (6) (6 ') is the one that can be added or reduced the pressure by the suspension structure, which will be described in more detail,

Drive motors 6 and 6 'spaced up and down are coupled to support rods 8 and 8' which are installed on both sides thereof by guide plates 9 and 9 ', respectively, to be moved up and down, and electric guide plates. The handles 11 and 11 'are screwed into the centers of the parts 9 and 9' by springs 10 and 10 ', respectively, which are piled up and down.

Accordingly, when the handles 11 and 11 'are rotated, the handles 11 and 11' are moved up and down, and the springs 10 and 10 'are moved up and down by the handles 11 and 11'. ), The pressing force is added and subtracted, and the separation distance and the pressing pressure of the driving motors 6 and 6 'can be varied.

The lower ones of these drive motors 6 and 6 'are coalesced on the support rods 8 and 8' by their own weight, and the upper drive motors are mounted on springs installed in the center of the support rods 8 and 8 '. It is constructed to be coalesced in the lower part.

Therefore, the user operates the handles 11 and 11 'described above to improve the paint removing effect of the masks 4 and 4' passed through the upper and lower brushes 7 and 7 '. When the pressure is increased or more pressure is applied than necessary, the wear of the mask (4) (4 ') is severe or the rotational force of the chain (2) is affected by the operation of the handle (11) (11'). It can be reduced.

Therefore, since the mask is not washed by a paint solvent using a conventional thinner or the like, the environmental pollution is prevented, and the secondary environmental pollution by the disposal of the paint solvent is also prevented.

In addition, since the paint for bar code base is painted to increase productivity, the volatiles are easily removed and dried after a certain period of time, so that the paint surface is made safe even by friction or contact. The injection nozzle 5 also has a problem that the residue of the paint is always left, so that the paint nozzle volatilizes and solidifies when waiting without spraying for a predetermined time, thereby clogging the spray nozzle 5.

Therefore, the present invention eliminates such a problem, so that even when the supply of the object to be printed is delayed or paused, the spray nozzle 5 can spray paint at a predetermined time interval, as shown in FIG. 4A. When the object is smoothly supplied, the printing holes 3 and scattering prevention ducts 19 of the masks 4 and 4 'are made to coincide with the centers of the spray nozzles 5, so that the barcodes can be transferred through the printing holes 3. When the base is secured to be sprayed with sufficient area to be printed, and the supply of the object to be printed is temporarily stopped or rested during the printing operation, the mask 4 and 4 'are fixed at a predetermined height, that is, as shown in FIG. Even though the area of the paint discharged through the spray nozzle 5 is moved so as not to invade the electric printer 3, the paint is scattered even though the spray nozzle 5 is sprayed at regular intervals. It is sprayed to the mask (4) (4 ') within the range of the prevention duct 19, the paint is not sprayed to the printing hole 3, there is no outflow of the paint, as well as the paint is continuously sprayed, Clogging of the injection nozzle 5 due to volatilization of the solvent does not occur at the time.

Therefore, when the object to be printed is re-inserted, reworking can be performed quickly by simply correcting only the positions of the masks 4 and 4 ', and clogging of the injection nozzle 5 also does not occur.

Since the curing time of the conventional bar code base paint is about 15 minutes or so, the intermittent injection time of the aforementioned injection nozzle may also be intermittently sprayed once or several times within the time.

In addition, the anti-scattering duct 19 is configured to enable the expansion and coupling of the duct plate (19a, 19b, 19c, 19d) of the required standard as shown in Figure 6, the anti-scattering duct (19) It is possible to quickly and easily remove the paint cohesive on the inner surface of the), and although not shown in the inner surface of the anti-scattering duct (19) detachably provided by replacing the adsorption cloth in the case of excessive adhesion of the paint to improve the work efficiency Various configurations can be devised, such as planning.

In addition, since the tip of the electric spray nozzle 5 is always buried, the paint on the outside thereof is cured after a certain time, and the cured paint falls off together by the pressure of the spray nozzle 5 spraying the paint. Since the sprayed paint adheres to the bar code printing surface and causes printing defects, and the cured paint accumulates gradually, the diameter of the tip portion of the spray nozzle 5 gradually decreases, thereby increasing the spray pressure as well as the spraying state. Inconveniently, conventionally, there has been a cumbersome process of cleaning the tip of the injection nozzle 5, which has been previously described by the user every predetermined time, with a paint solvent.

However, in the present invention, the rotary shaft 13 having the separate injection hole 12 is extended to the tip of the injection nozzle 5, and the connecting passages 14 and 14 'are provided on both sides of the tip of the injection nozzle 5, respectively. When the injection nozzle 5 is normally operated as shown in FIG. 5A, the injection hole 12 of the rotary nozzle 13 coincides with the tip of the injection nozzle 5. When the paint is sprayed to the outside, that is, the printing hole 3 of the mask (4) (4 '), and the injection hole 12 of the rotary shaft 13 is clogged or narrowed after a certain time has elapsed. As shown in FIG. 5B, the rotary shaft 13 is rotated so that the injection holes 12 connect the two connecting passages 14 and 14 ',

The paint solvent is rotated through the injection hole 12 through the solvent pump 17 and the solvent container 18 connected to the connecting passages 14 and 14 ', thereby causing the injection hole 12 to be blown by the paint solvent. By washing, to remove the solidified paint to improve the paint spraying state of the spray nozzle (5).

When the cleaning process is completed, the rotary shaft 13 is rotated again so that the tip of the injection hole 12 and the injection nozzle 12 coincide with each other, so that the paint for the bar code base is painted by the paint pump 15 and the paint container 16. Is to be injected.

Such washing and spraying operations can be smoothly progressed by repeatedly operating at a predetermined time by the user, and the productivity and productivity are reduced as well as the number of workers and work processes are reduced.

The bar code base painting apparatus of the present invention as described above improves the removal efficiency of the paint remaining in the mask, and when the supply of the article is stopped, the mask rises by a certain height and is sprayed at a predetermined time interval at the portion where the printing hole is not formed. This prevents paint from solidifying at the nozzle inlet and removes accumulated paint solidified by a separate cleaning means, which significantly reduces the defect rate while increasing productivity and shortens the work process as well as reducing the number of workers. It is effective to prevent environmental pollution.
