3 to 6, the printing unit 100 is a single printing roller 110 that rotates in contact with the outer circumferential surface of the outer cylinder of the syringe conveyed by the second index 22 and the printing roller A plurality of ink transfer units 120a and 120b disposed in a plurality of peripheries of the print roller 110 to transfer ink of each unique color to the outer circumferential surface of the print roller 110 by height, and the print roller 110 It is composed of a position adjusting unit 130 for adjusting the position of each ink transfer unit (120a, 120b).

The printing roller 110 is preferably made of a resin or silicone material having an outer circumferential surface elasticity in order to maximize the effect of printing performance. The printing roller 110 is installed adjacent to one side of the second index 22 so that the outer peripheral surface is in close contact with the outer cylinder of the syringe.

A driving motor (not shown) for driving the printing roller 110 is installed below the base 10. This drive motor rotates the printing roller 110 through a power transmission member consisting of a gear or a belt. The printing roller 110 may be controlled to the rotational speed by the power transmission member.

The ink transfer unit 120 may be provided in plurality for each color of ink printed on the outer cylinder of the syringe. In the present embodiment, two ink transfer units 120a and 120b are provided and described, for example.

Each of the ink transfer units 120a and 120b forms a body in common, and has a housing 121 in which ink is stored at the bottom, an intaglio roller 122 in which printing contents are engraved, and an ink stored in the lower portion of the housing 121. The coating roller 123 applied to the roller 122, and the blade roller 124 for wiping the ink applied to the negative roller 122 before the negative roller 122 is in contact with the printing roller 110. And each of the ink transfer unit (120a, 120b) is arranged in a plurality around the printing roller 110 to transfer the ink of different colors to the printing roller (110).

The intaglio roller 122 is preferably a metal material having excellent strength for the intaglio processing, and is disposed in front of the housing 121 to be in contact with the printing roller 110. The intaglio roller 122 may be engraved with a variety of contents, such as the scale to be printed on the outer cylinder for the syringe, the manufacturer, model name, production date, notices.

And the intaglio roller 122 is rotated independently through the drive motor (M1) installed in the base 10 lower. That is, the intaglio roller 122 penetrates the bottom of the housing 121 and is rotatably connected to a driving shaft connected to the driving motor M1 installed at the bottom of the base 10. In this case, the driving motor M1 may be installed to rotate the intaglio roller 122 while adjusting the rotation speed through a power transmission member made of a gear or a belt.

The application roller 123 is installed inside the housing 121 adjacent to the intaglio roller 122 and has a spiral groove 123c extending in the longitudinal direction on an outer circumferential surface thereof. The coating roller 123 is connected to the intaglio roller 122 through a first fixing bracket 125 fixed to one side of the housing 121 and a second fixing bracket 126 connected to the first fixing bracket 125. It is installed in close proximity, the lower portion of the spiral groove 123c is installed to be immersed in the ink stored in the lower housing 121. The second fixing bracket 126 is provided with a drive motor (M2) for driving the coating roller 123, the coupling portion with the housing 121 is formed with a slot hole (126a) for the coating roller 123 Position adjustment to the intaglio roller 122 side is made possible.
Therefore, when the coating roller 123 is rotated, the ink stored in the lower portion of the housing 121 is guided by the spiral groove 123c and rises to the top of the coating roller 123 along the spiral groove 123c. Continuous application is made to the outer peripheral surface.

The intaglio rollers 122a and 122b of the ink transfer units 120a and 120b are disposed at different heights so as not to overlap with the printing roller contact sections of the other intaglio rollers.

Therefore, at least one of the intaglio rollers 122a and 122b and the application rollers 123a and 123b as described above in a state where ink of different colors is stored in each of the housings 121 of the ink transfer units 120a and 120b. When is arranged at a different height, the ink of different colors for each height can be transferred to the outer peripheral surface of the printing roller 110.

On the other hand, the outer side of the coating roller 123 may be further provided with a guider 127 to maintain a predetermined gap along the outer circumferential surface of the coating roller 123. The guider 127 is formed spirally from the top to the bottom of the coating roller 123 while maintaining a constant gap along the outer circumferential surface of the coating roller 123. The guider 127 is fixed with the lower end immersed in the lower portion of the housing 121 together with the application roller 123.

In this case, when the application roller 123 is rotated, an ink film is formed between the guider 127 and the application roller 123, and the ink film thus formed is guided by the helical guider and naturally rises to the top of the application roller. Ink may be evenly applied to the outer circumferential surface of the application roller 123.

Further, when the spiral groove 123c is formed on the outer circumferential surface of the coating roller 123, the ink stored in the lower portion of the housing 121 rises along the spiral groove 123c through the guider 127 more smoothly and quickly. Can proceed.

The blade 124 is installed at the point before the intaglio roller 122 is in contact with the printing roller 110. The blade 124 is in line contact with the outer peripheral surface of the intaglio roller 122 with a predetermined force or more to wipe the ink applied to the outer circumferential surface of the intaglio roller 122 before the intaglio roller 122 contacts the printing roller 110.

Therefore, the blade 124 is preferably made of a soft material having excellent elasticity such as resin, silicone or rubber so that the ink applied to the outer circumferential surface can be easily wiped off.

On the other hand, the blade 124 is preferably provided with an adjustment screw (124b) to adjust the degree of close contact with the intaglio roller 122. In this case, the blade 124 is rotatably installed in an upright state through the bottom surface of the housing 121, the adjustment screw 124b is through the bracket 124a fixed to the outer wall of the housing 121 It is coupled to contact with a support extending from the outside of the body of the blade 124.

Therefore, when the tightening degree of the adjustment screw 124b is changed, the contact pressure to the intaglio roller 122 is adjusted while the rotational state of the blade 124 is changed, so that maintenance of the blade can be easily performed.

As shown in Figure 7 and 8, the upper portion of the base 10 is provided with a position adjusting unit 130 for adjusting the position of the printing roller 110 and the respective ink transfer units (120a, 120b). The position adjusting unit 130 is a first transfer robot 130a for reciprocating the printing roller 110 and the optional ink transfer unit 120a independently in one direction, respectively, and at least about the printing roller 110 at least. At least one second transfer robot 130b installed at least one and moving the ink roller unit 120b reciprocally in different directions on the same plane while moving in one direction together with the printing roller 110, and the first transfer robot ( 130a) and the main frame 130c on which the second transfer robot 130b is installed.

Of these, the first transfer robot (130a) is a transfer rail 131, both ends of which are fixed to the main frame (130c), is installed to be movable along the transfer rail 131, the printing roller 110 and any ink Spirally coupled to the first block 132 and the second block 133 on which the transfer unit 120a is placed, and to the first block 132 and the second block 133 through the main frame 130c, respectively. A first bolt 134 and a second bolt 135 are provided to impart a reciprocating movement force to the block that is spirally coupled during forward and reverse rotation.

Therefore, when the first and second bolts 134 and 135 are properly manipulated, the first block 132 and the second block 133 can be moved independently, and thus the first block 132 and the second block ( It is possible to finely adjust the distance between each printing roller 110 placed on the 133 and the optional ink transfer unit 120a. Through this, the adhesion between the print block 110 and the intaglio roller 122a can be finely adjusted.

And the center of the first block 132 and the second block 133 is a driving motor (120) of the intaglio roller 122a of the printing roller 110 and the arbitrary print transfer unit (120a), respectively, below the base 10 ( It is penetrated to receive power from M1). In addition, the upper surface of the base 10 corresponding to the movement trajectory of the printing roller 110 and the arbitrary print transfer unit 120a is moved by the printing roller 110 and the optional print transfer unit 120a. Of course, the opening is formed so as not to interfere with the upper surface of the).

The second transfer robot 130b may include a guide rail 136 having both ends fixed to the main frame 130c in parallel with the transfer rail 131 of the first transfer robot 130a, and the guide rail 136. A guide block 137 installed to be movable along the transfer block, and a transfer rail 138 fixed to the guide block 137 and the first block 132 and movable along the transfer rail 138. The third block 139 on which the other ink transfer unit 120b is placed is helically coupled to the third block 139 through the guide block 137 and reciprocated to the third block 139 which is helically coupled during forward and reverse rotation. It is composed of a third bolt 140 to impart a moving force.

Therefore, when the third bolt 140 is properly manipulated, the third block 139 can be moved to the printing roller 110 side along the transfer rail 131 and placed on the third block 139. The interval between the other ink transfer unit 120b and the printing roller 110 can be finely adjusted. Through this, the adhesion between the print block 110 and the intaglio roller 122b can be finely adjusted.

In addition, the center of the third block 139 is formed so that the intaglio roller 122b of the other print transfer unit 120b can receive power from the driving motor M1 installed under the base 10, and the other printing Of course, the upper surface of the base 10 corresponding to the movement trajectory of the transfer unit 120b is open so that the other print transfer unit 120b does not interfere with the upper surface of the base 10.

In this embodiment, the other ink transfer unit is installed and illustrated as an example, but when a plurality of different ink transfer unit is arranged for a variety of color printing, the second transfer robot (130b) of the other ink transfer unit It should be installed in a number to correspond to the number.

On the other hand, the ink inlet groove 111 formed horizontally on the outer circumferential surface of the printing roller 110 prevents bleeding between the ink transferred to the outer circumferential surface of the printing roller 110 by the intaglio rollers (122a, 122b). That is, when the ink transferred to the upper portion of the outer circumferential surface of the printing roller 110 by the intaglio roller 122b of the other printing transfer unit 120b flows down, the flowed ink is drawn into the ink inlet groove 111, so that any By the intaglio roller (122a) of the printing transfer unit (120a) of the printing roller 110 can be prevented from spreading with the ink transferred to the lower peripheral surface.

Therefore, the outer circumferential surface of the printing roller 110 is partitioned by the number of ink transfer units 120 through the ink inlet groove 111.

Referring to the process of performing color printing on the outer cylinder of the syringe using the outer cylinder color printing apparatus for a syringe of the present invention having such a configuration as follows.

First, when the printing apparatus is driven, the first and second indexes 21 and 22 are rotated and the outer cylinder of the syringe starts to be drawn out from the outer cylinder storage unit, and at the same time, the printing unit 100 is operated.

The operation of the printing unit 100 is made through the ink transfer units 120a and 120b operated simultaneously with the rotation of the printing roller 110. Each of the ink transfer units 120a and 120b constitutes the ink transfer units 120a and 120b. The printing roller 110 and the application roller 123 are rotated in the opposite direction to the second index 22 and the intaglio roller 122 rotates in the same direction as the second index 22 to perform a printing operation. At this time, the degree of adhesion between the printing roller 110 and each of the intaglio rollers 122a and 122b is already adjusted by the position adjusting unit 130 before the operation of the printing unit 100.

When the coating roller 123 immersed in the lower portion of the housing 121 is rotated, the ink stored in the lower portion of the housing 121 rises to the upper portion of the coating roller 123 through the spiral groove 123c of the coating roller. In the process, the ink is formed on the outer peripheral surface of the bracket and the ink film is formed adjacent to the coating roller due to the viscosity of the ink is thereby uniformly applied to the outer peripheral surface of the coating roller 123.

The intaglio roller 122 rotates in the opposite direction while maintaining a predetermined gap with the coating roller 123. The ink roller is formed on the gap by the viscosity of the ink applied on the outer circumferential surface of the coating roller 123. 123) The ink applied to the outer circumferential surface is evenly applied to the outer circumferential surface of the intaglio roller 122.

The intaglio roller 122 having the ink evenly coated on the outer circumferential surface is cleaned by the blade 124 just before the contact with the printing roller 110 in the process of rotation. The wiped ink flows down the blade 124 and is recovered to the lower portion of the housing 121 again, and the ink is infiltrated only in the recess groove.

Therefore, when the rotation of the intaglio roller 122 proceeds to come into contact with the printing roller 110, a small amount of ink remaining in the intaglio groove of the intaglio roller 122 is buried on the outer circumferential surface of the printing roller 110, thereby transferring. do. At this time, the intaglio rollers 122 of each of the ink transfer units 120a and 120b are disposed at different positions, so that the transferred ink is not duplicated.

As a result, ink of different colors for each height is collectively transferred to the outer circumferential surface of the printing roller 110 by the intaglio rollers 122, and then the outer cylinder passing through the first and second indexes in turn is printed roller 110. Since the printing is made in various colors while contacting the outer circumferential surface of the printing roller 110 in the process of passing through, the printing can be performed in various colors on the outer cylinder for the syringe through a single printing process without repeating several printing processes. Will be.

Meanwhile, the transferred ink of the printing roller 110 may flow down along the outer circumferential surface of the printing roller 110 during a long time of use, and in this case, the ink flowing down into the ink inlet groove 111 formed in the printing roller 110. Since the ink is introduced, the bleeding of the ink during the printing process can be prevented. The worker may periodically clean the ink collected in the ink inflow groove 111.

The operator freely adjusts the rotation direction and the rotation amount of the bolts of the position adjusting unit 130 by adjusting the gap between the outer cylinder and the printing roller 110 or the gap between the printing roller 110 and the intaglio roller 122. I can regulate it.

According to the outer cylinder color printing apparatus for a syringe according to the present invention configured as described above, a variety of information including a graduation displayed on the outer cylinder of the syringe by placing a plurality of intaglio rollers at different heights around the printing roller for printing to the outer cylinder They can be printed in color quickly and easily through a batch process.

While the invention has been shown and described with respect to specific embodiments thereof, it will be understood that the invention can be variously modified and modified without departing from the spirit or scope of the invention as set forth in the following claims. It should be included in the scope of the invention.
