Description

Object surface marking spraying system

technical field

The invention relates to a spraying system for marking the surface of an object, in particular to a spraying system for spraying markings on the surface of food.

Background technique

The proverb "people take food as their heaven" illustrates the importance of food to people. With the outbreak of several food safety incidents, food safety has become increasingly important to people. In addition to the relevant laws and regulations on the production process, more and more attention has been paid to the fact that natural foods are marked with their origin and production date.

In the past, the source or production date of food was mainly marked on the outer packaging. However, the food contained in the outer packaging can be easily replaced, so the label directly marked on the food is more credible. However, in the prior art, the method of setting labels on food is nothing more than sticking stickers on the outer surface of the food. This method requires pre-printing stickers and then sticking them one by one, which takes a lot of man-hours, and has some areas for improvement. .

SUMMARY OF THE INVENTION

In view of this, the purpose of the present invention is to provide a method for setting labels on food, so as to improve the time-consuming shortcomings of the prior art.

In order to achieve the above-mentioned purpose of the invention, the technical means adopted in the present invention is to provide a surface marking spraying system of an object, which includes:

a conveying platform with a conveying belt on it;

a main bracket, which is located on the side of the conveying platform;

A plurality of spraying components are connected with the main support and are relatively positioned above the conveyor belt. Each spraying component is arranged at intervals and includes a connecting rod and an inkjet unit. The inkjet units are arranged on the corresponding connecting rods, and the inkjet units are arranged in a stepped arrangement, and a buffer pad is arranged on the bottom side of each inkjet unit.

Further, each spraying component includes a restoring unit, and each restoring unit is respectively connected with the main support, the corresponding connecting rod and the corresponding inkjet unit, so as to drive the inkjet unit to return to a preset position.

Further, the conveying platform is provided with a sensing unit, and the end of the spraying assembly is provided with a sensing unit.

The advantage of the present invention is that the use of the spraying component can quickly and easily spray the logo directly on the object, and the stepped ink jet unit can spray more rows of objects corresponding to the limited width of the conveyor belt, and cooperates with the connecting rod. The pivoting arrangement allows the inkjet unit to move up and down according to the slight height difference between multiple objects to accurately spray the surface of the object, and cooperate with the setting of the buffer pad to protect the surface of the object from damage due to impact.

The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

In one embodiment, the aforementioned lateral adjustment assembly 40 and longitudinal adjustment assembly 50 can be automated adjustment units without manual manipulation.

In one embodiment, the present invention can be provided with a control computer 60 to control the ink jet volume of the spraying component 30 and the words or patterns to be sprayed, and can also control the automatic horizontal adjustment component 40 and vertical adjustment component 50 .

Please refer to FIGS. 9A to 12B , taking spraying eggs 70 as an example to illustrate the operation method and process of the present invention, but not limited thereto, the present invention can also be used to spray characters or patterns on other foods.

First, referring to FIGS. 9A and 9B , place the egg 70 to be sprayed with characters or patterns on the conveyor belt 11 . At this time, the height of the spraying assembly 30 is adjusted to a height suitable for the egg 70 , and the initial position of the egg 70 can be located at The left or right side of the spraying assembly 30 is not limited to the illustration. The conveyor belt 11 is activated so that the eggs 70 are driven toward the bottom of the spraying assembly 30. When the eggs 70 pass the first sensing unit 12, the control computer 60 That is, it is informed that there will be food passing through, and it is ready to be sprayed.

10A, 10B, 11A, and 11B, the egg 70 continues to advance and contacts the inkjet unit 32, and each inkjet unit 32 sprays the contacted egg 70 with a preset mark 80. The unit 32 has a certain length, so the stepped arrangement can make the relative position of each inkjet unit 32 staggered, and can correspond to the position of each row of eggs 70 in a standard egg carton, then each inkjet unit 32 corresponds to a row Egg 70 position. Since the size of each egg 70 is different, there will be a slight drop in height. The taller egg 70 will push the inkjet unit 32 in contact with it, so that it drives the connecting rod 31 to move upward to match the height of the egg 70 . At this time, the impact force generated when the ink jet unit 32 contacts the egg 70 is absorbed by the buffer pad 323 to avoid breaking the egg shell when the egg 70 pushes the ink jet unit 32 to move upward.

12A and 12B , the conveyor belt 11 continues to advance so that all eggs 70 pass under the inkjet unit 32 , and completes the work of spraying the logo 80 on all eggs 70 , and when the eggs 70 are separated from the inkjet unit 32 Afterwards, the inkjet unit 32 that is moved upward by force is returned to the original height by the action of the restoring unit 33, so as to carry out the subsequent spraying operation. Please refer to FIG. 13A and FIG. 13B further, the form of the logo 80 can be designed according to requirements, and can be a text logo 80 as shown in FIG. 13A , or a quick response matrix code 80A (Quick Response Code, QRCODE for short) to connect to a specific web page, the specific web page can present the production history, date of manufacture, expiration date and other information of the food.

Please refer to FIG. 14A and FIG. 14B . Taking spraying cantaloupe 71 as an example, since the cantaloupe 71 is larger than an egg, the horizontal adjustment component 40 can be appropriately used to adjust the positions of the spraying components 30 in the array, so that the positions of the cantaloupe 71 in each row are respectively adjusted. The vertical adjustment assembly 50 can be used to adjust the height of the spraying assembly 30 in advance, so that its initial height conforms to the average height of the cantaloupe 71 , so as to facilitate the operation of spraying and marking the cantaloupe 71 .

To sum up, the present invention achieves the purpose of rapid spraying by directly spraying the logo on the object through the spraying component. The step-like inkjet unit is used to target objects arranged at small intervals (such as boxed eggs). Carry out the spraying operation, and use the pivoted connecting rod to make the inkjet unit move up and down to respond to the slight height difference of each object, and the setting of the buffer pad can avoid the inkjet unit and the object. The force of the impact can damage the surface of the object.

Of course, the present invention can also have other various embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding Changes and deformations should belong to the protection scope of the appended claims of the present invention.
