The present invention relates to a printing position adjusting device of a disposable syringe scale automatic printing machine, and when printing the scale on the outer circumferential surface of the disposable syringe with the disposable syringe scale automatic printing machine, the syringe user can easily check the scale of the syringe when using the syringe. It relates to a device for fixing the orientation of the syringe so that the graduation can be printed.

Conventional syringe printing position adjusting device is a patent application registered application No. 92-1217 of the present application, the printing device for printing on the outer circumferential surface of the container, Japanese Patent Laid-Open No. 48-92109, Japanese Patent Laid-Open No. 58- In the 25864 publication, the above-mentioned Japanese Patent Application Laid-Open No. 48-92109 communicates with the inside of the hollow rotating drum 101 connected to the decompression device in order to hold the to-be-printed object in a direction parallel to the rotating shaft 102. A large number of ruminant requests 103 formed with 104 are arranged in parallel, and the to-be-printed material supplied in the request 103 has a drum b 101 having a length b between the outer circumferential surface and the request 103. In the state of adsorption holding by the air flow flowing into the negative pressure chamber 101a in the It is.

Therefore, the above-described conventional printing apparatus holds the container in the ruminant request 103 formed on the outer circumferential surface of the rotating drum 101 by the air flow flowing into the negative pressure chamber 101a of the rotating drum 101. As the printing is performed while maintaining the holding state, the printing is performed on the surface after holding the container correctly in the request 103 rather than simply printing at a certain position of the container. However, there is a drawback that cannot be done.

In addition, it is necessary to adjust the flow of air in the matching chamber 101a by calculating a friction coefficient so that the object to be printed and the electronic roll 106 do not slip, as well as the size of the hole 104 of the material selection request 103. There are drawbacks such as the need to calculate the diameter.

Further, in the latter Japanese Laid-Open Patent Publication No. 58-25864, the simple rotating plate 108 is attached to the output end 107a of the short rotary drive unit 107 provided at the proper position of the main frame 111. The sun gear 109 is pivotally arranged on the outer circumference of the pivot plate 108 to install the planetary gear 110 and rotates in the same period as all the sun gear 109 and the planetary gear 110. Install a chuck 112 to fix the plurality of screen printing units 129 in the vicinity of the chuck 112 so as not to support the driving of the short rotating plate 108, and the short rotating plate 108 rotates briefly. In this state, the screen printing unit 129 moves forward in the state of the same period as the rotation of the chuck 112 so as to press the to-be-printed material, thereby printing the to-be-printed plate. Spring-loaded chuck 112 into a suitable chucking position In addition, the short rotating plate 108 is accompanied by a simple rotation in a predetermined direction, and moves to the rear with the rack 113 stationary near the front direction as a driving source to rotate the to-be-printed object and at the same time avoid the screen printing unit 129. Screen printing is performed while pressing the to-be-printed object by moving at the same speed as the rotational circumferential speed of the printed matter.

Therefore, screen printing may be performed in multiple colors on the outer circumferential surface of the container. However, if the outer circumferential surface of the container is to be printed in the correct position, such as a syringe, this may not be performed.

At present, the disposable syringe scale automatic printing machine is operated when the syringe is supplied to the printing device of the printing machine, so that the syringe is inserted into the circular syringe insertion groove to be transported. As a result, the direction in which the graduation was printed on the outer circumferential surface of the syringe was not constant.

In the case of using a syringe, since the support jaws of the left and right sides of the syringe are supported by the recognition and the middle finger, and the piston of the syringe is pressed with the thumb, the scale is not printed on the outer circumferential surface of the side without the support jaws of the syringe as shown in FIG. In addition, when the scale is printed on the side with the base as shown in Figure 7, it is inconvenient to check the scale while holding the syringe.

In order to solve the above problems, the applicant of the present invention devised a printing position adjusting device of the disposable syringe automatic printing machine so that the scale can be printed at a position where the scale can be easily checked when the syringe is used as shown in FIG. And the printing position adjusting device of the disposable syringe automatic printing machine of Utility Model Application No. 92-1217.

The printing position adjustment device is attached to the guide plate for inducing the direction of the syringe to be transported on the syringe transfer plate so that the syringe is transported while maintaining a constant direction, by attaching the direction adjustment bar to the printing position the syringe is transferred to the printing position When the end of the direction adjustment is to adjust the direction by pushing the base of the syringe as appropriate.

However, the above printing position adjusting device is designed to press the syringe body to prevent the syringe from rotating excessively due to inertia when the end of the direction adjustment pushes the support base of the syringe. Since the syringe direction adjustment by the pushing method is inferior in accuracy, there was a problem that the error of the position where the scale is printed is somewhat large.

In order to solve this problem, the present invention attaches a rotating disk of the same size to the upper portion of the disk for transporting the syringe, and attaches a plurality of syringe fixtures to the upper and lower sides of the disk so as to move upward and downward, A circular cam was attached so that the syringe fixture could operate up and down while rotating so that the direction of the syringe could be more accurately fixed.

The present invention is designed to move up and down along the cam as the syringe fixture rotates integrally with the syringe transfer plate. When the syringe is supplied to the syringe transfer plate, the syringe fixture descends to fix the direction of the syringe constantly, and the syringe prints. When it is in position, it rises and the syringe rotates with the printing roller so that the graduation can be printed.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 4, the present invention is perforated at a predetermined interval around the coupling hole (2) is inserted into each of the coupling holes (2) to enable the syringe fixture (4) to move up and down, The combined rotary disc 6 is attached to the syringe transfer plate 8 so as to rotate integrally with the syringe transfer plate 8 at a slight interval on the top of the syringe transfer plate 8 of the known disposable syringe scale automatic printing machine, and the syringe transfer plate ( The outer side of the 8) is a circular cam (10) is attached so that the syringe holder (4) can be moved up and down when the rotating disk 6 and the syringe transfer plate (8) rotates.

It can be fixed so as not to rotate in the syringe insertion groove (12).

On the outer circumference of the syringe fixture 4 protruding annular 14 is protruded in the lower portion, the anti-rotation jaw 15 is protruding in one side of the central portion, the snap ring coupling groove 16 is provided in the upper portion, The coil spring 18 is inserted and coupled to the outer circumference of the upper portion 14, and the screw portion 20 is formed on the upper portion thereof, the locking jaw 22 is protruded on the lower portion thereof, and the rotation preventing groove 23 is provided therein. The coupling ring 24 is inserted and coupled thereto, and a snap ring 26, which is held inward so that the coil spring 18 and the coupling ring 24 do not fall, is fixed to the snap ring coupling groove 16.

The syringe fixture 4 inserts the coupling ring 24 coupled to its outer circumference into the coupling hole 2 of the rotary disk 6 from the bottom to maintain a constant direction, and then from the top to the fixing nut 28. It is attached to the rotating disc 6 by fixing. At this time, only the coupling ring 24 is fixed so as not to flow to the rotating disc 6, the syringe fixture 4 is able to move up and down in the coupling ring 24 while the coil spring 18 is pressurized and relaxed, Rotation prevention jaw 15 protruding on the outer circumference is inserted into the rotation prevention groove 23 of the coupling ring 24, thereby maintaining a constant direction without rotation.

The syringe fixture 4 is attached to the wheel 30 to be rolled along the circular cam 10 on one side of the protruding annular 12 formed on the lower outer periphery, the syringe holder 4 is the bottom surface of the syringe A syringe fixing groove 32 of upper and lower beams in which an upper support jaw can be inserted and fixed is provided, and the syringe fixture 4 is hollow so as to penetrate up and down. The syringe pressing rod 34 is inserted to be rotated integrally with the syringe and is supported by the coil spring 18a downwardly.

The inside of the syringe fixture 4 is wide and the upper portion is narrow so that the locking jaw 22a is formed so that the syringe pressing rod 34 coupled to the inside thereof does not fall out, and the syringe pressing rod 34 is formed at the upper portion thereof. Snap ring coupling groove (16a) for fixing so as not to escape to the top after being coupled is contemplated. On the other hand, the syringe pressing rod 34 has a lower portion is thick and the upper portion is thin, so that the engaging jaw 22d is formed on the outer circumference, the screw hole 36 is formed on the upper surface of the syringe pressing rod 34.

The syringe pressing rod 34 has a bearing 38, a spacing retaining ring 40, a bearing 38a, a spring bearing ring 42, a coil spring 18a on an upper portion of the engaging jaw 22d formed on the outer circumference thereof, After inserting and engaging the flow ring 44, the side bearing 46, the flow ring 44a, and the release preventing ring 48 in sequence, the screw 50 is inserted into the syringe pressure rod 34 to prevent them from escaping upward. After coupling to the screw hole 36 formed on the upper surface of the), it is inserted into the inside of the syringe fixture (4), and then fixed to the snap ring (26a) is carried out to the snap ring coupling groove (16a).

At this time, the syringe pressure rod 34 is caught by the engaging jaw 22a formed in the interior of the syringe fixture 4, the bearing 38 coupled to the outer circumference, so as not to escape to the lower portion of the syringe fixture 4, the syringe pressure When the outer diameter of the screw head of the screw 50 coupled to the upper surface of the rod 34 is larger than the inner diameter of the release preventing ring 48 coupled to the lower portion thereof, the syringe pressing rod 34 below the release preventing ring 48 is combined. All components coupled to the 1) do not come out of the upper portion, and the syringe pressure rod 34 does not come out of the syringe fixture 4 by the snap ring 27a.

As shown in FIGS. 4 and 5, the circular cam 10 attached to the outside of the syringe transfer plate 8 has a high portion of the syringe supply groove 52 for supplying the syringe to the rotating disc 6. It is gradually lowered toward the printing roller 54, and quickly becomes the middle height in the printing roller 54 portion, and then rises again after passing the printing roller 54 to maintain the high state until the syringe feed groove 52 portion. have. Therefore, as the wheel 30 attached to one side of the protruding annulus 14 of the syringe fixture 4 rolls around the circular cam 10, the syringe fixture 4 moves up and down. Reference numeral 56 denotes a syringe outlet groove for discharging the graduated syringe, 58 denotes a syringe insertion groove 12 recessed in the syringe transfer plate 8 to prevent the syringe from escaping to the outside while being transported. To prevent the release of the syringe, 60 is the shaft screw for attaching the wheel 30 is attached to one side of the protruding annular 14 protruding in the syringe fixture 4, 62 is the support jaw on the left and right of the syringe, 64 is the Cap insert.

The operation process of the present invention configured as described above is as follows.

When the syringe scale automatic printing machine is operated, the syringe transfer plate 8 and the rotating disc 6 attached to the upper portion by the motor (not shown) rotate in the direction of movement of the clock hand as seen from the top. When the syringe body is inserted perpendicularly to the groove of the syringe feed slot 52, and the support jaw 62 on the left and right sides of the syringe is fed to the syringe transfer plate 8 with the left and right sides of the syringe feed slot 52, the syringe is One by one is inserted into the syringe insertion groove 12 recessed in the syringe transfer plate 8 and conveyed toward the printing roller 54.

As shown in FIG. 5 (a), since the height of the circular cam 10 is high in the syringe supply groove 52, the syringe insertion groove 12 when the syringe is inserted into the syringe insertion groove 12. The syringe fixture 4 located at the top of the coil spring 18 is pushed up while being pressed, so that the syringe can be inserted into the syringe insertion groove 12 without being interrupted by the syringe holder 4. While the syringe is inserted into the syringe insertion groove 12 and transported toward the printing roller 54, as shown in FIG. 5 (b), the height of the circular narrow cam 10 is gradually lowered, so that the syringe fixture 4 is lowered. The upper base jaw 62 of the syringe is fixed.

Since the syringe fixing groove 32 recessed on the bottom of the syringe holder 4 has a shape of upper and lower light, the direction of the syringe inserted into the syringe insertion groove 12 while the syringe holder 4 is lowered is slightly changed. Even if it is changed, the locking jaw of the upper portion of the syringe can be accurately fixed between the syringe fixing groove (32). While the syringe holder 4 holds the syringe in the direction of the syringe, the syringe push rod 34 inserted into the syringe holder 4 is raised while the bottom surface thereof is pressed on the upper portion of the syringe and the coil spring 18A is pressed. Press and hold the syringe.

When the syringe is transported to the position of the printing roller 54, as shown in Fig. 5 (c), since the circular cam 10 is quickly brought to the middle height, the coil spring 18 is pressed and the syringe fixture 4 The half rises, and the support jaw 62 of the syringe leaves the syringe fixing groove 32 of the syringe holder 4. However, the syringe pressing rod 34 inserted into the syringe fixture 4 is pressed by the cap spring 64 of the upper portion of the syringe while being lowered by the coil spring 18a. At this time, the syringe pressure bar 34 is pressed down the upper portion of the syringe in a state not completely lowered.

When the printing roller 54 rotates to print a scale on the outer circumference of the syringe body, the syringe body is rotated in engagement with the printing roller 54. At this time, since the syringe pressure rod 34 holds the syringe, the syringe and the syringe The pressure rod 34 is rotated together. The friction between the outer circumferential surface of the syringe pressurization rod 34 and the inner surface of the syringe holder 4 is reduced, the friction with the upper snap ring 26a is reduced by the side bearing 46, and the upper snap ring by the side bearing 46 is reduced. Friction with (26a) is reduced and rotation is smooth.

When the syringe passes the printing roller 54, as shown in Figure 5 (a), the circular cam 10 is raised again, the coil spring 18 is pressed while the syringe fixture 4 is raised The syringe is completely out of the syringe fixture 4, and the syringe push rod 34, which is inserted into the syringe fixture 4, remains completely lowered and still maintains a constant distance from the top of the syringe. When the syringe is transferred to the syringe outlet groove 56, the graduated syringe is discharged, and the syringe holder 4 is moved toward the syringe supply slot 52 while being raised.

Therefore, the present invention is designed so that the syringe fixture 4 fixes the syringe while the syringe is inserted into the syringe insertion groove 12 of the syringe transfer plate 8 and is transported toward the printing roller 54. Solving the conventional problem that the direction of the syringe becomes inconsistent due to the syringe body not being fixed, such that the syringe body hits the syringe escape preventing plate 58, so that the graduation can be printed on a constant direction of the outer peripheral surface of the syringe body. .

In the present invention, if you want to slightly adjust the direction in which the scale is printed according to the thickness of the syringe, loosen the fixing nut 28 coupled to the upper part for each syringe fixture 4, and then the direction of the syringe holder 4 in the desired direction. After adjusting, tighten the fixing nut 28 again. Since the scale of the syringe is preferably printed between one base 62 of the syringe and the other base 62, the printing starts in a direction similar to the direction when the syringe is fed from the syringe feed slot 52. It should be possible.

In the present invention, even if there is no syringe push rod 34, the purpose can be achieved, but in this case, when the syringe fixture 4 is raised in the vicinity of the printing roller 54, the syringe push rod 34 is pressing the syringe Unlike the case, since the direction of the syringe may move finely, some errors may occur in the printing position. And the purpose of the present invention can be achieved even by removing the bearings 38, 38a and side bearings 46 coupled to the syringe pressure rod 34, but in this case, the rotation of the syringe is somewhat smooth during graduation printing. There is a problem.
