Hereinafter, a handgun for an inkjet marking apparatus according to the present invention will be described with reference to the drawings.

Figure 4 is an embodiment of the present invention, Figure 4a is a partial cut-away configuration of the present invention, the inkjet marking apparatus handgun according to the present invention is an inkjet printer (1) for printing by spraying ink on the printing object And a body 3 coupled with the inkjet printer 1 and a hinge 1b and having a camshaft 4 coupled thereto, a motor 5 for driving the camshaft 4, and the inkjet printer Composed of a block (6) coupled to (1) and moved along the camshaft (4), the block (6) coupled to the inkjet printer (1) is a camshaft (rotated by a motor (5) Reciprocate along 4).

Figure 5 is another embodiment of the present invention, Figure 5a is a partial perspective view of Figure 5, Figure 6 is a side view of the configuration of Figure 5, the inkjet marking apparatus handgun according to the invention the ink on the printing object Inkjet printer (1) for reciprocating movement by printing by spraying, the body (3) formed on one side of the inkjet printer (1), the saddle formed between the inkjet printer (1) and the body (3) A plate 8, a motor 5 housed in the body 3, a pair of pulleys 9 and 9 'rotated by the drive of the motor 5, and a pair of pulleys 9, 9 ') coupled to the power transmission belt (9a), the camshaft (4) rotated by the pulley (9') for driving the inkjet printer 1 reciprocating, and the inkjet printer (1) It is coupled to one side of the block 6 is moved along the camshaft 4 and consists of an operation switch 7 for generating an operation signal.

Reference numeral denotes a reset switch 7a.

Here, the body 3 is configured in a box shape so that components such as a motor 5 can be accommodated therein, and a guide groove 3a is formed on an upper surface of the body 3 to move the saddle plate 8. Guide me.

The saddle plate 8 is fixedly coupled to the inkjet printer 1, one end of the block 6 is coupled, the other end is coupled to one or more guide rollers (3b).

The block 6 is penetrated by the camshaft 4 and reciprocates along the grooves 4a and 4b formed in the camshaft 4.

The motor 5 is preferably configured as a servo motor capable of adjusting the forward and reverse rotation and position and speed.

A pulley 9 is connected to the shaft of the motor 5, and a pulley 9 ′ corresponding to the pulley 9 at a predetermined distance is connected by a belt 9a. As a result, the power transmitted to the pulley 9 is transmitted to the camshaft 4.

7 is an exemplary configuration diagram of a camshaft according to the present invention, wherein the camshaft 4 has a conveying groove 4a in which the block 6 is guided at the printing stroke and a returning groove in which the block 6 is guided at the return stroke. (4b) is formed differently, respectively.

That is, the conveying groove 4a in which the block 6 is guided at the printing stroke is formed between the grooves so that the transfer of the block 6 is relatively slow, and the returning groove in which the block 6 is guided at the return stroke ( 4b) is configured to be wide between the grooves so that the block movement is fast.

This is because the inkjet printer 1 sprays ink through the injection port 1a during the printing stroke so as to slow down the feeding speed so that a sufficient amount of ink can be ejected, and the inkjet printer 1 draws the ink during the return stroke. This is to speed up the feed in order to return to the home position faster because it does not spray.

In the camshaft shown in FIG. 7, the printing stroke of the inkjet printer 1 is completed only when the rotation of the camshaft is performed in seven rotations. However, the camshaft is transferred to the conveying groove 4a and the returning stroke of the inkjet printer 1 by only three rotations. The return groove 4b is formed differently.

Looking at the operation of the present invention as follows.

FIG. 8 is a view illustrating the operation of FIG. 4, and FIG. 8A is a view illustrating the operation of FIG. 5 in which the inkjet printer 1 and the printing object P have a slightly shifted angle from the parallel state during printing.

When the switch is pressed after bringing the handgun close to the object to be printed, the printing stroke and the return stroke of the inkjet printer 1 are started.

First, in the printing administration, the block 6 and the inkjet printer 1 coupled to the saddle plate 8 start at a position at one end of the camshaft 4 and are completed when the end is reached to the other end.

Since the block 6 is fixedly connected to the saddle plate 8 and the saddle plate 8 and the inkjet printer 1 are also fixedly coupled, the inkjet printer 1 and the saddle plate 8 and the block 6 are eventually connected. Will move together.

At this time, two guide rollers (3b) are formed on one side of the saddle plate (8) is moved along the guide groove (3a) formed in the body (3), the guide groove (3a) formed in the body (3) ) Is formed at an angle with respect to the camshaft 4, so that the block 6 can be smoothly moved and the inkjet printer 1 can be made small so as to have an angle α formed by the print object P. Make sure

That is, as shown in FIG. 8, if the rear side (the side where the ink supply line is coupled) of the inkjet printer 1 is fixed, a large amount of force is required to transfer the inkjet printer 1 and the block 6. ), And the angle (α) formed by the inkjet printer 1 and the printing object (P) becomes large, making accurate printing difficult.

Unlike this, if the guide groove (3a) is formed in the body as shown in Figure 8a, the guide roller (3b) coupled with the saddle plate 8 is moved along the guide groove (3a) and eventually the inkjet printer 1 Since the rear side moves together along the guide groove 3a, the force for transporting the block 6 is relatively small, so that the capacity of the motor 5 is not large, and the inkjet printer 1 and the printing object P This angle α is made small so that accurate printing is possible.

After the return stroke, the block 6 moves along the return groove 4b formed in the camshaft 4, so that the inkjet printer 1 returns to its original position much faster than the print stroke.

As described above, the present invention provides a handgun for a more automated inkjet marking apparatus which can print on a printing object as a reciprocating stroke of the inkjet printer itself without a driving roller and a guide roller, and printing is completed only by a switch operation.

In particular, the present invention is applied to the CIJ printer device for marking a product by transferring the product to the automation line, it is very useful for marking a product that is difficult to move, that is, difficult to mark the transfer to the product on the automation line It is suitable for small quantity products of various kinds, such as aviation industry.

Furthermore, even in the case of a severely curved product, ink can be sprayed on a constant basis, and a handgun for an inkjet marking apparatus capable of printing without direct contact with a printing object is provided.

In addition, by forming the printing groove and the return groove differently in the camshaft, it is possible to shorten the time required for the return stroke compared to the time required for the printing stroke of the inkjet printer.
