Description

Surface marking spray system

The present invention is a spraying system for marking the surface of an object, particularly a spraying system for spraying markings on the surface of food.

The proverb "food is the heaven for the people" explains the importance of food to people. With the outbreak of several food safety incidents, food safety is becoming more and more important to people. In addition to stricter additives and preparations for processed foods In addition to the relevant laws and regulations of the process, the labeling of the origin and production date of natural foods is also increasingly important.

In the past, the source or production date of food was marked on the outer packaging. However, the food contained in the outer packaging is easily replaced, so the label directly marked on the food is more reliable. In the prior art, the method of setting a mark on the food is nothing more than sticking a sticker on the outer surface of the food. This method requires pre-printing the sticker and then pasting it one by one, which consumes a lot of man-hours and needs improvement.

In view of this, the present invention focuses on the research on the method of setting the label on the food, in order to improve the time-consuming shortcomings of the prior art.

In order to achieve the above-mentioned object of the invention, the technical means adopted by the present invention is to provide an object surface marking spraying system, which includes: a conveying platform with a conveying belt on it; a main support, which is located on the side of the conveying platform; Spraying components, which are connected to the main support and relatively located above the conveyor belt. Each spraying component is arranged at intervals and includes a connecting rod and an inkjet unit. Each connecting rod is pivotally connected to the main support and each inkjet The units are arranged on the corresponding connecting rods, and each ink-jet unit is arranged in a stepped arrangement, and a cushion pad is arranged on the bottom side of each ink-jet unit.

Furthermore, each spraying assembly includes a recovery unit, and each recovery unit is respectively connected with the main bracket, the corresponding connecting rod and the corresponding inkjet unit to drive the inkjet unit to return to a preset position.

Furthermore, a sensing unit is provided on the conveying platform, and a sensing unit is provided at the end of the spraying assembly.

The advantage of the present invention is that the spraying assembly can be used to spray the logo directly on the object quickly and easily. The stepped inkjet unit can spray more rows of objects on the limited conveyor belt width and cooperate with the connecting rod. The pivotal setting of the inkjet unit enables the inkjet unit to move up and down according to the slight height difference between multiple objects to accurately spray on the surface of the object, and cooperate with the setting of the cushion to protect the surface of the object from damage due to impact.

Please refer to FIG. 9A to FIG. 12B. The spraying egg 70 is taken as an example to illustrate the operation mode and process of the present invention, but not limited to this. The present invention can also be used to spray text or patterns on other foods.

First, please refer to Figures 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 spray assembly 30 is adjusted to a height suitable for the egg 70. The initial position of the egg 70 can be The left or right side of the spraying assembly 30 is not limited to the illustration. The conveyor belt 11 is started to drive the egg 70 to travel under the spraying assembly 30. When the egg 70 passes through the first sensing unit 12, the control computer 60 will know There will be food passing and preparation for spraying operation.

Next, please refer to FIGS. 10A, 10B, 11A, and 11B. The egg 70 continues to advance and touches the inkjet unit 32. Each inkjet unit 32 sprays a preset logo 80 on the contacted egg 70. The unit 32 has a certain length, so the stepped arrangement can make the relative positions of the inkjet units 32 stagger, and can correspond to the position of each row of eggs 70 in the standard egg carton, then each inkjet unit 32 corresponds to a row The position of the egg 70. And because the size of each egg 70 is different, there will be a slight drop in height. The higher egg 70 will push the inkjet unit 32 it touches to drive the connecting rod 31 to move upward to match the height of the egg 70 At this time, the cushion 323 absorbs the impact force generated when the ink jet unit 32 contacts the egg 70 to avoid breaking the egg shell when the egg 70 pushes the ink jet unit 32 to move upward.

Finally, referring to Figures 12A and 12B, the conveyor belt 11 continues to advance so that all the eggs 70 pass under the inkjet unit 32, and the operation of spraying the marks 80 on all the eggs 70 is completed, and when the eggs 70 leave the inkjet unit 32 After that, the inkjet unit 32 that is forced to move upward is returned to the initial height by the action of the recovery unit 33 for subsequent spraying operations. Please further refer to Figure 13A and Figure 13B. The appearance of the logo 80 can be designed according to requirements. It can be a text logo 80 as shown in Figure 13A, or a Quick Response Code 80A (Quick Response Code) as shown in Figure 13B. , QR CODE for short) to link to a specific web page, which can display the food’s production history, manufacturing date, expiration date and other information.

Please refer to Figures 14A and 14B. Taking the spraying of the cantaloupe 71 as an example, since the cantaloupe 71 is larger than an egg, the horizontal adjustment assembly 40 can be used to adjust the position of the array of spraying components 30 to separate the rows of cantaloupe 71 The vertical adjustment component 50 can be used to adjust the height of the spraying component 30 in advance so that the initial height matches the height of the cantaloupe 71 so as to facilitate the operation of spraying the logo on the cantaloupe 71.

To sum up, the present invention directly sprays the logo on the object through the spraying assembly, and achieves the purpose of rapid spraying. With the stepped inkjet unit, it is aimed at objects arranged at a smaller interval (such as boxed eggs). The spraying operation is performed, and the pivoted connecting rod is used to make the inkjet unit move up and down to respond to the slight height difference of each object, and the buffer pad is set to avoid the occurrence of when the inkjet unit contacts the object. The impact force will damage the surface of the object.

The above is only an embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed in the above embodiment, it is not intended to limit the present invention.
