Inking device for label printing and applying machine

This invention relates to a coloring device for use in a label printing and applying machine. In particular, the invention relates to a Improvement in a dyeing device for use in a hand-held or portable label printing machine and applying machine or the like, with the device the type surfaces of a print head can be evenly colored for accurate label printing.

In the conventional label printing and applying machines for stickers, the devices are for applying of color on the surface of the tyre in such a way that

709883/0707

TELEPHONE (OBO) 33 9B «a TELEX OS-9SS8O TELEGRAM MOtMAPAT TELECOPIER

that in most cases dye rollers are attached to the free ends of spring-loaded pivot arms, and the Dye rollers are pressed against the type surfaces and rolled over them to apply color.

For example, in a typical stainer, these are Kind in the conventional art a pair of spring-loaded swing arms at the front end portion of the machine body appropriate. Furthermore, a support frame carrying dye rolls is attached to the swing arms with springs. When the hand lever and the handle of the machine are squeezed together, the above mentioned Swivel arms are pivoted and the support frame is moved at the same time as this activity. Thus becomes the dye roll unrolled along the type surfaces of the print head, applying paint to the type surfaces.

This exemplary structure is described in detail in a later section for reference.

The conventional paint apparatus described above has the following disadvantages:

a) Because the dye roller in contact with the type surfaces is brought about by spring action, the application of paint is exposed to the risk of deterioration, when the force of the spring is weakened after using the machine for a long time. That is why the pressure is on the labels blurred, which has the worst disadvantages compared to an optical reading system that is highly precise Requires prints.

b) When the spring force wears off, then only the paint will be in the section near the surface of the dye roller used, the dye roller is not pressed by the type surfaces, _iind the color that is in

Central section of the dye roller is soaked, does not seep out. That is why printing a lot of labels impossible, which is uneconomical.

c) If the hand lever is squeezed together quickly, the dye roller sometimes only receives a light or no contact at all with the type surfaces, due to the rebound effect. Thus, a more reliable Pressure not expected.

A strong force is required to operate such a label printing machine, so that operators especially weak female operators, while handling over one getting tired for a long period of time.

e) In the conventional machine, the swivel arms, the support frame and the dye rollers are moved forward into the The front part of the machine body moves when the hand lever is fully compressed, so take the

protruding parts allow operators to see when the printed label is applied to the surface of a commodity, and accurate application of the label cannot be performed well.

In view of the above-described drawbacks caused in the conventional art devices occur, it is proposed according to the present invention to eliminate such errors.

It is therefore the primary object of the present invention to provide an improved staining device which is incorporated in a Label printing and applying machine is to be built in, with the necessary force to squeeze the hand lever is effectively reduced to simplify the operation of the machine.

Another object of the present invention is to provide a printing apparatus for a label printing and applying machine Provide, with dye rollers in contact with type surfaces with always cleaner and even intensity be brought to apply an even and suitable amount of paint to the type surfaces, whereby one achieves an accurate and even printing of the labels over a long period of time.

Another object of the present invention is to provide a coloring apparatus for a label printing and applying machine to provide, wherein the dyeing rollers are carried by a multi-link bracket mechanism that by the squeezing action of the hand lever is stowed in the inside of the machine housing. Thus can the obstruction to the operator's view must be removed to allow the application of labels to the surfaces of goods to facilitate.

Still another object of the present invention is to provide a coloring apparatus for a label printing and applying machine of the type described above, the staining device being simple in construction and durable in use and further can be easily produced at a low cost.

In accordance with the present invention, the multi-link bracket mechanism of the dyeing device yoke arms, which are actuated by pressing a hand lever, a support member for supporting the dye rolls; and a plurality of hinge brackets that operate the yoke arms and the support member together associate. A guide device for guiding the dye rolls is formed in the above-mentioned bracket mechanism. Furthermore, when the hand lever is fully pressed, the ironing mechanism moves the dye rollers to the inside

709883/0707

the same section of the label printing and applying machine, to be stowed in it.

The above-mentioned bow mechanism is also equipped with a pair of fixed pivot points or pivot pins, which are attached to the machine frame, other two

Pairs of fixed pivot points that are attached to the yoke arms, and several pairs of movable ones Pivot points or pegs, which all connect the hinge brackets with one another. Furthermore, the bracket mechanism is with a pair of spring-actuated operating brackets attached to one pair of fixed pivot points, and a pair of pivot brackets attached to the other pair of fixed pivot points on the yoke arms. the The above-mentioned guide device for the dye rolls comprises support shafts which are attached to the support part of the dye rolls and slots formed in the brackets to guide the support shafts.

A special idea of the invention lies in a coloring device which is to be built into a label printing and applying machine or the like and which facilitates the clear and precise printing of labels with constant and uniform application of color to the surfaces of the printing types. The dyeing apparatus has a multi-link bracket mechanism comprising yoke arms which are operated by pressing a hand lever, a support member for carrying the dye rollers, a plurality of brackets which operatively connect the yoke arms and the support member, and guide means formed in the hinge brackets to guide the dye rolls. The dyeing device is characterized in that, when the hand lever is pressed, the multi-link bracket mechanism moves the dyeing rollers in the direction of the housing of the label printing and applying machine and the dyeing rollers are picked up here. 709883/0707

The above and other objectives and characteristics of the The present invention will become even more apparent to the person skilled in the art from the following description, made in connection with the attached drawings in which

709883/0707

Reference will now be made to the accompanying drawings, wherein, the preferred embodiment of the present invention Invention will be described in detail.

Simply for reference, a typical staining apparatus construction is now being suggested in the conventional art described in the first place. As shown in Fig. 9, two swing arms 103 are swingable at the end portion of a machine frame 101 fixed, and they are urged counterclockwise by a spring 102. At the free ends the pivot arm 103 is pivotably articulated to a support frame 105, which is also operated in a counterclockwise direction by a spring 104 is pressed. A dye roller 106 is rotatable and fitted to the free ends of this support frame 105 in a suitable manner.

When a handle 107 and a hand lever 108 are pressed together, yoke arms 109 are rotated downward, and the cams 113 formed on the above swing arms 103 are depressed by the projections 110 provided on the free ends of the yoke arms 109. Thus, the swing arms 103 are rotated clockwise, and along with this operation, the support frame 105 is shifted to the left. Thus, the inking roller 106 is moved and rotated in contact with the type surfaces 112 of a printing head 111 while applying paint to the type surfaces 112.

The conventional dyeing machine having the one described above Mechanism has several disadvantages as follows:

a) Since the dye roller 106 against the type surfaces 112 is pressed by means of the springs 102 and 104, the contact pressure of the dye roller 106 is against the type surfaces 112 exposed to the risk of waning,

709883/0707

when the force of the springs becomes tired due to fatigue after a long period of time and repeated use. the Application of paint cannot be performed satisfactorily in such a state, and the The impression in the label print becomes indistinct. Especially when a label printing machine is used to print labels used for optical readers that use laser beams, for example, is the obscurity A critical mistake in printing, as high accuracy printing is required for optical reading.

b) When the spring force decreases, then the printing type surfaces not pressed into the dye roller, so that the stored in the inner section of the dye roller Color does not ooze out and so only the color that is in the sections near the surface of the dye roller is available. Accordingly, the possible number of printings that can be performed becomes reduces what is uneconomical.

c) When the hand lever 108 is pressed on quickly and instantly is, the dye roller sometimes does not come into contact with the type surfaces 112 due to the counteraction to such a rapid movement. Furthermore, in some cases, the dye roller leads such a weak touch that the desired pressure on the labels cannot be achieved.

d) It takes a great force to squeeze the handle 107 and the hand lever 108 together because when they are fully compressed, it is necessary to exert a counterforce against the force of a drive spring 114 on the Inside of the handle 107 is stretched and the hand lever 108 and the yoke arms 109 always in a counter-clockwise direction squeezes, and exert the force to move the dye roller 106

70 9883/0707

to move against the force of the springs 102 and 104 , ie the force to press down the cams 113 with the end portions 110 of the yoke arms 109 and to rotate the swivel tub 103.

Therefore, it has become very difficult for workers, especially weak female workers, to do so To use label printing machines continuously over a relatively long working hour .

e) Further, when the had lever 108 is fully squeezed, the pivot arms 103, the support frame 105 and the dye roller 106 are pushed out at the front portion of the label printing machine, and therefore when the printed label 116 is applied to the surface of a commodity under an applicator 115 It is difficult to see the label 116 because of the obstacles formed by the swing arms 103 and other parts, so that it becomes difficult to see the printed label 116 . to apply exactly to the desired location on a product.

In order to overcome the above-described disadvantages in the devices according to the prior art, the color device proposed according to the present invention.

upwardly protruding portion 22 of the swivel bracket 21 occurs. That is, the fixed pivot points 5 and 6 on the yoke arms 40 are moved downwards, so that the movable pivot point 17 on one side of the drive bracket 16, which is on the machine frame 44 is attached, is moved to the right, while another movable pivot point 18 on the other Side of the bracket 16 is almost moved upwards. At the same time, the swivel bracket 21 is turned counterclockwise the fixed pivot point 6 rotated.

In detail, the support member 36 and the support shaft 34 for the dyeing roller frame 41, so parts that to the upper End of the vertical slot 23 are pressed by the spring 25, to the right end portion of the horizontal Slot 28 of the guide bracket 27 through the swivel bracket

21 led. Practice the sliding activity described above the inking roller 42 under spring force a first coloring action on the surfaces of the types 46 of the print head 4 5, as shown in FIG.

Simultaneously with this first application of paint / since the swivel bracket 21 is rotated counterclockwise about the fixed pivot point 6, the upwardly projecting portion

22 of the bracket 21 pressed against the contact pin 8 of the operating bracket 7, which is in engagement with the other operating bracket 30 stands, and thus the mechanism is moved to the state shown in FIG.

If 'the stop of the upwardly extending portion 22 against the contact pin 8 overcomes the force of the spring 12, then the operating bracket 7 is further clockwise rotated, and as a result, the engagement between the operating bracket 30 and the engaging projection 10 of the Actuating bracket 10 (see Fig. 5) released, whereby the operating bracket 7 and 30 in the released state

709883/0707

are set. In other words, an operating bracket 7 is pivoted clockwise about the fixed pivot point 5, while the other operating bracket 30 is pivoted counterclockwise about the movable pivot point 29. Together With the activity described above, the second dye roller 43 gives the end faces of types 4 6 a second Paint application.

When this second application of paint is finished, then achieved the support shaft 34 of the dye roller is the right end of the horizontal slot 28 of the guide bracket 27.

If the hand lever 2 is further compressed, as shown in FIG. 8, then both the guide bracket 27 and the swivel bracket 21 rotated counterclockwise, together with a simultaneous movement of a each pivot point, whereby the dye rollers are received in the central portion of the machine frame 44. In detail the dyeing roller frame 41 supporting two dyeing rollers is formed vertically, and the end portion (on the

Side of the support shaft) of the support member 36 holding the frame is received in the accommodation recesses 55 (See FIGS. 4 and 5, in particular) which are formed in the underside of the yoke arms 40. Thus becomes the first dye roll 42 held between the yoke arms 40, and the second dyeing roller 43 is below the above-mentioned dyeing roller and held on the back of the print head 45. Accordingly, the dye rolls can be housed efficiently to eliminate the useless space, and the entire body of the label printing machine can be made compact will.

In addition, the stop projection 9 of the actuating bracket 7 comes into contact with the connecting bracket 15, so that the rotation of each bracket 7 is stopped. Furthermore, the end faces of the types 46 of the print head

In the next step, when the hand lever 2 is released, the multi-link bracket mechanism returns to its rest position 5, and at the same time the printed label unit 56 is placed under the applicator 57 to be applied to the surface of any commodity.

When operating the dye rollers 42 and 43 described above, the first dye roller 42 is placed on the end faces of the types 46 always unrolled under a certain pressure by the guide device, because the support shaft 34 in the end portion of the Support member 36 is guided and moved in the horizontal slot 28 of the guide bracket 27. Accordingly, if the The dye roll 42 is unrolled over the types 46, then the outer surface of the roll 42 is forcibly depressed so that, when the depressed portion of the dye roller 4 2 returns to its original shape, the color that is in the middle Section of the dyeing roller 42 is stored, seeps out to the outer surface of the dyeing roller 42 by itself. That's why can be the application of paint to the faces of the types

46 must always be carried out evenly and sufficiently.

Is further after the unrolling of the first dyeing roller 42, the second dyeing roller 43 in contact with the end faces of the Type 46 brought where the second dye roller 43 is actuated by the spring 25, but then the carrier 58 is on both sides unrolled on the lower surface of the print head 45, and therefore the second inking roller 4 3 can be on the Type 46 end faces can be unrolled without unnecessary pressure to complete the inking process to undertake. Accordingly, the application of paint

709883/0707

without unevenness effortlessly through such an additional Effect can be achieved.

As described above, the coloring apparatus of the present Invention has the following advantages:

a) The ink-impregnated part of the above-mentioned dye rollers are in contact with the end faces of the types below brought to a certain pressure by means of a movable guide mechanism, and therefore the amount of ink, which is applied to the end faces of the types, always evenly, and the exact pressure on the labels can be achieved without errors.

b) As a device for pressing the dye rollers against the faces of the types under constant pressure mainly uses the yoke mechanism, which is different from conventional devices that use spring action, differs. Therefore, the force that is required to depress the hand lever can be Minimum turning and operator fatigue can be greatly reduced.

c) It is prevented that the dye rollers and the bracket are led out of the machine housing at the front when the hand lever is pressed, and they can be inside the machine housing by means of a streamlined ironing mechanism can be stowed away. Therefore nothing obstructs the view in the front section the label printing machine, and the exact application of labels to the surfaces of the goods can be done without further to be accomplished.
