Abstract

PURPOSE: A prescription sheet printing saving device of a medication package machines is provided to efficiently use and reuse the ribbon by supplying a print unit and a ribbon saving device of an improved structure. CONSTITUTION: Dispatch is stopped while a dispatching roll shaft winding a ribbon is clicked. The dispatching roll shaft moves only as much as a printed area. The tension of a sensitive plate(61) and a weight sensitive bar(60) becomes a released state on the ribbon. At the same time, a sensitive piece unit of an end of the sensitive plate descends and gives a sensitive signal to a sensing switch(64). The sensitive signal transfers to a central control unit and drives a motor(45) for driving the winding roll shaft. Then, the tension is fed to the ribbon again so that the sensitive plate and weight sensitive bar ascend and keep in a printing wait state.

Description

Saving mechanism for ink ribbon of medicine package

The present invention relates to a device for saving a printing ribbon of a pharmaceutical packaging machine, and more particularly, to an improvement of a printing unit that is applied to various kinds of pharmaceutical packaging machines to perform printing on the packaging paper.

Widely used in large hospitals and pharmacies, the medicine packaging machine prepares each prescription medicine by printing the prescription instructions, the name of the patient, and the date according to the patient on the surface of a series of continuous band-shaped wrapping paper. The medicine is injected and sealed.

This kind of medicine packing machine is widely used in large hospitals where various kinds of medicines are prepared and performs a large amount of medications, and a plurality of containers for classifying drugs, slides and parallel packaging containers driven in parallel with the containers. It is an integrated machine that has a feeding section, a printing section on a pharmaceutical packaging paper, and the like.

In such a device of the related art, the pharmaceutical packaging paper is made of a transparent or translucent paper or vinyl, etc., and is hung on a pair of feeding shafts having a roll shape wound and made into a strip shape that can be continuously cut to a long length. Supplied. In addition, a ribbon containing a printing head and ink for performing printing on the pharmaceutical packaging paper is also provided to perform the printing on the pharmaceutical packaging paper.

In the conventional configuration, the ink ribbon or the thermal transfer ribbon for printing is fed at the same feeding speed and distance as that of the pharmaceutical packaging paper, so that ink or transfer ribbon of the same length as the pharmaceutical packaging container is required for printing. As a result, the relatively expensive waste of ribbon was severe.

The printing unit U of the saving device of the printing ribbon of the medicine packaging machine which the example structure is shown as a perspective view in FIG.

It is mounted on the lower inner side of the entire drug packaging machine (not shown), and after feeding and feeding the wrapping paper, the medicine is added and sealed. Such a configuration is disclosed in a variety of sources and the like. Only the printing unit U will be described.

The printing base 1 which is processed by metal plate etc. is connected to the front cover base 2 and the hinge shaft 3 so that the cover base 2 is rotated to the front side to open and the drawing of such an open state is 2 degrees. . The printing base 1 is attached to the fixing bracket 4 from above to increase the structural strength.

On the fixing bracket 4, the first guide shaft 10 and the second guide shaft 11 serve as guide rods for guiding and supplying the packaging paper P fed from the feeding roll of the packaging paper (not shown). The printing roll bracket 21, which is mounted and receives the elastic factor roll 20, such as a rubber material, is also fixed upright on the fixing bracket 4. As shown in FIG.

The printing head shaft 13 is shown as a front view in FIG. 3, and the printing head 25 is rotatably attached to the end of the head arm 24 to the printing roll bracket 21, which is an extended cantilever shaft guide. The drive actuator 26 pivotally drives the head arm 24 with (13) as the axial center to perform printing on the elastic factor roll 20. As shown in FIG. The print head 25 may be used in various ways such as a conventional thermal transfer method.

The encoder bracket 50 is mounted on the middle portion of the printing roll bracket 21 to be fixed upright, and the encoder arm 51 hinge-fixed to the encoder bracket 50 is connected to the bullet body, and the encoder 52 is connected to the end thereof. Is mounted, and the encoding disk 53 of the encoder 52 is connected to the second guide shaft 11.

On the other hand, the ribbon R is inserted into the feeding roll shaft 30 which is erected to the printing base 1 in the state of being wound on the initial branch pipe or the winding holder 40 and the like and freely fixed to the rotation, and is also spaced apart from each other. The take-up holder 41 is also fitted to the take-up roll shaft 31, which is freely fixed to allow upright rotation, so that mutual feeding and take-up are possible. 45 is a ribbon guide shaft for guiding the ribbon (R).

The rotation of the take-up roll shaft 31 is controlled by the motor 45, and a specific control mode will be described later.

The feed roll shaft 30 has a structure for limiting its rotation on the rear surface of the printing base 1, which is a plate member, and as shown in FIG. 3, the feeding roll shaft 30 is formed on the outer periphery of the same axis as the feed roll shaft 30. 70 is formed in a uniform tooth on the circumference coaxially with the feeding roll shaft 30, and the clicking bar 72 is rotatably fitted to the shaft pin 71 fixed upright to the printing base 1.

The click king bar 72 is a rack-shaped body having teeth on one side thereof, which makes gear connection with the click king tooth 70, and the click king bar 72 overcomes the elastic force of the spring 74 by the driving actuator 73. By driving up and down, the feeding roll shaft 30 is rotated.

In the winding roll shaft 31, as clearly shown in Figs. 2 and 4,

A weight sensitive bar 60 for sensing the state of the ribbon R is mounted upright, and a sensitive plate 61 is installed to freely rotate on the take-up roll shaft 31.

The free end side of the sensitizing plate 61 is bent to have a sensation piece 63 which can be flowed between the guide grooves 62 integrally so that the sensation piece 63 cooperates with the sensing switch 64 to perform the below-described action. It is preferable that the length of the guide groove 62 be approximately equal to the width of the printing area G to be printed, as apparent from the operation described below.

As the above-mentioned configuration, the wrapping paper P is

Packing paper not shown again, passing between the second guide shaft 11 and the encoding disk 53 via the first guide shaft 10, which is a rod-shaped body, and between the elastic factor roll 20 and the print head 25. It is fed to the dosing and sealing device of (P). An exemplary example of the wrapping paper P is shown as a top view in FIG. 5,

Encapsulated paper that can be cut along the perforation line (L) with other adjacent wrapping paper (P), and the name of the medication, the dosage method, the precautions, the number of doses, etc. are printed in a number of lines on the front. It is preferable that the saving device of the printing ribbon of the pharmaceutical packaging machine of the present invention is applied to the packaging paper having the area G.

On the contrary, the ribbon R passes through the feeding roll shaft 30 between the guide shaft 33 and the encoding disk 53 from the feeding roll shaft 30 to the lower side of the wrapping paper P, and the elastic factor roll 20 and the printing head ( 25) is also sent to the take-up roll shaft 31 via the weight-sensitive bar 60, which is also fixed upright on the induction plate 61 via via.

A drive motor (not shown) of the drive shaft of the feed roll 100 to wind the drug wrapping paper, a motor 45 for driving the take-up roll shaft 31 to drive the feed roll shaft 30, and a drive. The sensing switch 64 which emits a sensitive signal by the actuator 26 and the sensitive piece 63 is transmitted to the central control unit, which is also a control unit of the entire medicine packaging machine, to control the operation.

The effect of the saving device of the printing ribbon of the pharmaceutical packaging machine of this invention is demonstrated to the said structure.

The wrapping paper P is formed between the second guide shaft 11 and the encoding disk 53 via the first guide shaft 10, which is a rod, together with the ribbon R, the elastic factor roll 20, and the printing head 25. Extends into and feeds,

Accordingly, the encoding disk 53 feeds the encoding signal to the central control unit to transmit information about the current feeding speed and the control speed.

As shown in Fig. 4A, upon receiving a print command from the central control device, the print head 25 is placed on the ribbon R by the driving actuator 26 with respect to the wrapping paper P with respect to the elastic factor roll 20. Will be executed in close proximity to

Since the printing is usually performed in the printing area G having a plurality of rows, the printing head 25 is operated by the driving actuator 26 to perform printing while repeating the action of dropping and attaching the wrapping paper P several times. ,

At the same time, the driving motor of the drive shaft of the roll for winding the wrapping paper P is rotated and the winding roll 31 of the ribbon R is driven.

In this state, the click king bar 72 engaged with the click king tooth 70 of the feeding roll shaft 30 of FIG. 3 overcomes the elastic force of the spring 74 by the driving actuator 73, and is upward of the click king tooth 70. The feeding of the ribbon R is freely performed between the areas of the printing in a state where the cleaking is released by moving to.

In this process, the wrapping paper (P) and the ribbon (R) are moved almost together, and once the printing is finished,

The drive motor of the drive shaft of the roll winding the wrapping paper P is operated so that the wrapping paper P is positioned between the elastic factor roll 20 and the printing head 25 with another adjacent wrapping paper P '.

During this operation, the click king bar 72 engaged with the click king tooth 70 of the feeding roll shaft 30 of FIG. 3 is contracted by the driving actuator 73 and the elasticity of the spring 74 causes the click king bar 72 to move. Since the tooth is connected with the click king tooth 70 and the rotation is limited, the feeding of the ribbon R is not made.

That is, the feeding roll shaft 30 wound around the ribbon R is clicked on and stops feeding further and only moves by the printed area to be fed.

Therefore, the ribbon R is in the same state as the ribbon R 'of FIG. 4B, and the induction plate 61 and the weight sensitive bar 60, which are freely rotated and fitted to the take-up roll shaft 31, have a tension on the ribbon R. The state is released (a).

At the same time, the sensitive piece 63 of the end of the sensitive plate 61 is lowered to cause a sensitive signal to the sensing switch 64,

This sensitive signal is transmitted to the central controller to rotate the motor 45 for driving the take-up roll shaft 31 (b),

Accordingly, tension is applied to the ribbon R again so that the sensitive plate 61 and the weight sensitive bar 60 are raised to maintain the printing standby state.

The above operation is repeatedly performed according to the feeding of other adjacent ribbons R, R ', R "... So that the printing of the entire ribbon R is performed uniformly.

Therefore, the printing is performed on the ribbon R without damaging the printing portion due to the application of excessive tension, and transfers only as much as the row area for printing, so that the ink or transfer area capable of printing the ribbon R can be used as much as possible. Will be.

In the above configuration, since the control mode of the central control apparatus can be implemented as a device having various programming means, it is not described in the present invention.

The above-described saving device for printing ribbon of the pharmaceutical packaging machine of the present invention makes full use of the printing area G of the ribbon R, so that the printing area is printed using the entire area without the idle area of the ribbon R. Cost is minimized, and the cost is reduced.
