DE1611917C2 - Hand-held device for printing, dispensing and attaching self-adhesive labels adhering to a carrier tape - Google Patents

Description

The invention relates to a hand-held device for printing, dispensing and attaching to a carrier tape Adhesive self-adhesive labels to objects of any shape, with a housing with a hollow Handle and an actuating lever which is mounted on the housing and can be swiveled into the hollow handle, which is held in the spread position by a spring, with a pull-off device for the label tape, Consists of a driven feed roller that rotates when the actuating lever is swiveled out and a pressure roller that is resiliently pressed against this, with a supply reel for the label tape a printing unit made of type wheels and a counter pressure device which can be moved relative to one another and between which the label tape is passed and printed before the feed, with mechanical connections on the one hand between the operating lever and feed rollers and with one of the Counterpressure device associated deflection edge, on which the label coming into dispensing position is almost completely detached from the carrier tape and is provided in front of an elastic pressure roller through which it can be pressed onto the object to be labeled.

Devices of this type are used, among other things, in department stores, supermarkets, self-service shops etc. used to label the goods. The label comes with the price, in-store labels, possibly imprinted with the amount of VAT, etc. and accessed by a user on the goods to be labeled pressed on.

In a known hand-held device, the counter-pressure device is through the base plate of the housing formed and the printing unit consisting of the type wheels can be displaced perpendicular to the base plate. The type wheels that form the printing unit can be opened from the outside by turning adjustment wheels also twist, which changes the price printed on it, etc. One of the users of these devices The request made to the manufacturers is to have the printing unit as close as possible to the issuing point to be arranged so that it was the first to be printed with the new setting when the type wheels were adjusted Label reached the issuing point as quickly as possible. In other words, with a new one Label provided with an imprint should appear as soon as possible at the issuing point, without the need for a Larger number of labels showing the old print are in the housing and donated first Need to become. This not only has the disadvantage that the labels showing the old print are lost, but also the operational disadvantage that you have to label "empty" a few times before the new imprint appears at the issuing point. Often too little is achieved as a result of inattentiveness or fatigue Labeled "empty" so that a piece of goods to be labeled is often still with the previously set price, etc. is printed, which leads to annoyance. It should be noted that the handheld devices are especially in department stores can only be operated by semi-skilled workers. In the known device can be a certain The minimum distance between the printing unit and the issuing point should not be less than a length of about two corresponds to five labels. After changing the printing unit, there are still around two to five labels with old imprint donated.

In the known device, the printing unit cannot be placed directly next to the issuing point. One reason for this is that the printing unit has a certain minimum height. If you wanted it placed directly next to the issuing point, the device would be very high there at its tip. One could Then no longer put it in tight spaces, such as in shoes, to attach labels. It would also make it more difficult to aim the device to accurately apply a label to a small area.

The type wheels forming the printing unit have a certain diameter that is not below the limit can be. This diameter also requires a certain minimum distance from the dispensing point or the elastic pressure roller. The distance must be at least equal to half the diameter of the Be type wheels. 6o

The invention is based on the object of providing a hand-held device of the type mentioned at the outset for Printing, donating and attaching self-adhesive labels on a carrier tape to any to form shaped objects so that the printed label is always donated and sent to one Object is attached so that incorrect labeling with a label with a wrong impression is not possible more is possible. To solve this problem, the invention provides that the counter-pressure device in the form one rotatable about a fulcrum fixed to the housing and one film drum guiding the label tape comprehensive pressure crucible is formed, which by means of the actuating lever between a pressure position Can be swiveled on the type wheels, which are fixedly mounted in the housing, and on the label dispensing position is that the feed rollers are mounted on the pivotable pressure platen and that also the pressure roller for the labels at the front end of a lever mounted on a fixed pivot point in the housing is arranged, which is pivotable by means of the hand lever that it is at the end of each Label feed movement is placed on the label located on the front of the pan in the dispensing position.

The invention has thus departed from the view that the counter-pressure device is stationary stand and the type wheels must be movable. With such a construction you do not come below a minimum distance between the printing point and the issuing point, which is at least the length of corresponds to a label. The device according to the invention is characterized in that the type wheels are stationary are mounted in the housing and the counter-pressure device is in the form of a pivot point in the housing stored and by the operating lever between a rest or pressure position and the dispensing position has pivotable pressure platen. This pressure crucible thus has a double function. Once he forms that The counterpressure device and, on the other hand, it transports the label from the printing position to the dispensing position. The Label tape is guided over the printing platen past the type wheels around which the deflection device forming leading edge of the printing platen deflected and then passed through the take-off device, wherein the extraction device consists of a rotatably mounted in the pressure platen and is pivoted when the Actuating lever rotating take-off roller and a counter-pressure roller elastically pressed against it consists, wherein the pressure roller pressing the label onto the item of goods continues at the front end a lever is attached, which is pivotably mounted about a pivot point in the housing and with the Actuating lever is in operative connection in such a way that the pressure roller is at the end of a feed movement placed on the label located in the dispensing position above the item of goods.

Due to the mobility of the printing platen according to the invention with the pair of feed rollers attached to it and the pivotability of the pressure roller ensures that the last one printed Label Provided Immediately: An affixing of a label with an even from an earlier setting resulting impression value on an object is excluded. Immediately after changing the printing unit by turning the type wheels, the new imprint appears on the label to be dispensed. Trouble with the Customers and complaints are no longer to be feared, even if the handset is inattentive Trainees are used, the connection between the adjustment of the type wheels and the Do not pay attention to the appearance of a correctly printed label on the deflecting edge of the device.

The most expensive individual part of the handheld device by itself, the type roller consisting of the type wheels, lies protected and immovable in the device. This immovability of the heavy Typerl roller leads

also to the fact that the masses to be moved are comparatively small compared to known devices. this not only reduces user fatigue, but also leads to one with the same amount of effort higher top speed of the printing unit or printing platen. This promotes an accurate and sharp Pressure.

Another advantage results from the accommodation of the film drum in the otherwise unused space inside of the pressure crucible. This means that the film drum does not take up any special space for itself would lead to an enlargement of the device.

Due to the pivotability of the pressure roller lever bearing and in particular by its indirect connection with the spring arranged in the handle results in the further advantage that the pressure roller in hard Serving object to be labeled feathers something on the can and auswei- chen. ¹ The resilient suspension of the pressure roller absorbs the impact resulting from a hammer-blow-like pressure. You can also label individually and apply the device precisely to small areas, e.g. B. on the crown caps of lemonade bottles.

The device can be modified by using plastic and aluminum for less stressed parts produce with low weight. Interlocking parts such. B. journals, bearings and Guide slots are made of high-alloy steels and / or hardened. This results in a largely permanent freedom from play and a sufficient service life even with rough operation.

Appropriate refinements of the invention form the subject matter of the subclaims. Using the example of In the embodiment shown in the drawing, the invention will now be further described. It is

F i g. 1 is a plan view of the essential parts of the device with the housing shells removed, namely. in the dispensing or dispensing position and with the actuating lever pivoted out,

F i g. 2 shows a corresponding view with a simultaneous schematic representation of a housing shell, namely in the pressure position of the device with the actuating lever swiveled in,

F i g. 3 shows a schematic plan view of the printing platen, the film drum, and the take-off device below simultaneous display of the path of the label tape and

F i g. 4 shows a view of the type edges and the film drum from a viewing direction rotated by 90 °.

F i g. 2 shows a housing shell 10 to which the fixed immovable handle 14 is rigidly connected. With the Handle 14 works together with the pivotable actuating lever 16. Between handle 14 and Actuating lever 16 is a compression spring, not shown, which the two levers in the in F i g. 1 shown Spread position or rest position pushed apart. The label tape supply 20 in the form of a supply reel is arranged above the handle 14. The label tape 22 winds from the label tape supply 20 from, the path of which is shown in FIG. 3 is shown. The operating lever 16 is fixed to the housing around a Pivot point 24 pivotable. It is forked towards the front, and this fork is located in one leg A slot 26 is located. In this slot 26 there is a pin 28 which belongs to a rocker arm 30. The rocker 30 is pivotable about a pivot point 31 fixed to the housing. At its front end it carries an inking roller 32.

This inking roller 32 is used to inking the printing unit or the type wheels 34. These type wheels 34 can be adjusted individually with a printing unit adjusting axis 36 shown schematically in FIG will.

In the lower leg of the fork of the operating lever 16 there is a cam slot 38. In the Curve slot 38 runs a pin 39. This pin 39 belongs to a lever 40. The lever 40 is around a fulcrum 41 fixed to the housing can be pivoted. At its front end it carries the elastic pressure roller 42.

The pressure crucible 46 can be pivoted about a further pivot point 44 fixed to the housing. Its front end forms the deflecting edge 47. The pressure crucible 46 is connected to the actuating lever 16 via a lever 48. This lever 48 is seated on pins 52 and 54, which extend from the actuating lever 16 and pressure platen 46. A Projection 56 of lever 40 presses on lever 48 and holds it on pins 52 and 54.

The film drum 58 sits loosely on the axis or the pivot point 44 fixed to the housing. 4 shows the prongs 60 on the circumference of the film drum 58, which fits into the notches on the two edges of the label tape 22 intervene. A large gear 62 is non-rotatably seated on one end face of the film drum 58. This gear 62 meshes with a smaller gear 64 which is seated in a rotationally fixed manner on the feed roller 66. The draw roll 66 is rotatable about an axis 68. This axis 68 is mounted in the pressure crucible 46. An elastic counter pressure and draw roll 70 cooperates with draw roll 66. The counter-pressure roller 70 is seated on one End of a rocker 72 which can be pivoted about an axis 74. The axis 74 is in a projection stored, which proceeds from the pressure crucible 46. On the axle 74 there is also a spring that acts as the counter-pressure roller 70 presses against the feed roller 66.

A ratchet wheel 78 is also seated on one end face of the film drum 58. A pawl 80 engages in this ratchet wheel a, which is pivotable about a pivot point 82 fixed to the housing. She is under the influence of a spring, not shown, which presses it against the ratchet 78.

After the above detailed description, a complete workflow will now be described. The Handheld device takes the one shown in FIG. 1 shown rest or spread position, in which the spring, not shown the actuating lever 16 pushes off the handle 14. First the label tape 22 is inserted. For this the rocker 72 is pivoted about its axis 74 in a clockwise direction. You can extend it by about 90 ° the in F i g. Pivot 1 tilted position and then comes across a stop at which it stops. the The beginning of the label tape 22 is withdrawn from the label tape supply 20, between the film drum 58 and feed roller 66 pushed through, turned over around the deflecting edge 47 and then between feed roller 66 and counter-pressure roller 70 pushed through. The rocker 72 is then pivoted counterclockwise in the position shown in Figure 3, in which the label tape 22 between the two rollers 66 and 70 is jammed. For further preparation, the type wheels 34 are rotated into the desired position.

If now the operating lever 16 from the in F i g. 1 into the in F i g. 2 position shown is pivoted, the following happens:

The pressure crucible 46 is pivoted clockwise via the lever 48. He takes that Label tape 22 with that on its underside 49

rests on (see Fig. 3). When the in Fig. 2 The end position shown presses the platen 46 a label against the type wheels 34, so that this label is printed. The inking roller 32 has moved past the type edges 34 with a time advance and colored them. During this inking movement, the rocker 30 swings in a clockwise direction around the pivot point 31 fixed to the housing. The drive takes place via the pin 28, which passes through the slot 26 of the Operating lever 16 is taken. The inking roller 32 rolls on the type wheels 34 and colors them before each printing process. The inking roller 32 is impregnated with paint that is essential for many hundreds of Printing processes is sufficient.

Simultaneously with this rotation of the platen 46, the film drum 58 also rotates by one Label length. The film drum 58 sits loosely on the axis of the platen 46. Nevertheless, it does so Clockwise rotation with. The counter pressure roller 70 is by the spring against the Draw roller 66 printed. This in turn is coupled to the film drum 58 via the gears 64 and 62. The feed roller 66 rotates together with the platen 46 about the pivot point 44. About its own Axis 68, however, the feed roller 66 cannot rotate because it is attached to it by the counter-pressure roller 70 is prevented. As a result, it takes the film drum 58 with it, and the label tape 22 becomes the length of one Label peeled off. It hangs up on the film drum.

When the actuating lever 16 is pivoted in, the lever 40 also swings with the pressure roller 42 in Clockwise direction. The pin 39 forcibly guided in the cam slot 38 forces the oscillating movement of the lever 40. During the printing process, the pressure roller 42 is in the end position shown in FIG. One too many dispensed label that moves around the deflection edge 47 from the carrier strip when the carrier strip has solved, lies with its front edge under the pressure roller 42. It will be the next donation "Too much" printed on the object to be labeled. This then only receives two Labels, which doesn't do any harm. But it is avoided that the excess label in the device falls back and there the guides etc. clogged.

While the rocker bearing the inking roller 32 oscillates at a constant angular velocity, increases the angular velocity of the lever 40 at the end of the upward movement. This results from the Curve shape of the cam slot 38. This ensures that the pressure roller 42 does not hit the Inking roller 32 hits and there is always a sufficient distance between these two rollers.

After the operator by pressing the operating lever 16 and handle 14 together Has triggered the movements explained above and thus printed a label, she now leaves the operating lever 16 go. Under the pressure of the spring it is in the pivoted or dispensing position shown in FIG. 1

emotional. At the same time, the operator holds the tip of the hand-held device over the one to be labeled Surface and performs a slight pulling movement so that the pressure roller 42 applies the label dispensed to the Surface rolls up. While now the operating lever

ίο 16 from the position shown in FIG. 2 into the position shown in FIG moves, the following happens:

Under the action of the lever 48, the pressure platen 46 swings about its counterclockwise direction Pivot point 44. This pivoting or rotating movement

the film drum 58 cannot participate. When rotated in a clockwise direction, the pawl 80 runs via the teeth of the ratchet 78. When rotated counterclockwise, the pawl 80 pushes however, against the flanks of the teeth of the ratchet wheel 78, preventing any rotation of the film drum 58. Correspondingly, the gear 62 cannot rotate either. The feed roller 66 must, however, the pivot and take part in the rotary movement of the pressure platen 46, since it is rigidly connected to this. The same applies

the gearwheel 64, which is firmly seated on the feed roller 66. This gear 64 now rolls up like a planetary gear a sun gear on gear 62. It turns. The feed roller 66 rotate accordingly and the counter-pressure roller 70. The feed roller 66 rotates in a counterclockwise direction about its axis 72. The carrier strip is taken along. That is, on the deflection edge 47, a label from Carrier strip loosens. This release takes place during the entire movement of the deflecting edge 47 on one

Circular path between the two positions of FIG. 2 and 1. In the end position shown in Fig. 1 has a label almost completely detached from the carrier strip and lies with its leading edge under the pressure roller 42, which has meanwhile also moved downwards.

This movement is constantly increasing in speed, so that the front edge of the dispensed label by the rapidly approaching pressure roller 42 vigorously is pressed onto the object to be labeled. This completes the printing and dispensing process.

In the following, the position of the pressure crucible 46 in the dispensing position of the device will be briefly explained. the F i g. 1 and 3 show that a donated and separating from the carrier strip at the deflection edge 47 Pushes the label exactly under the pressure roller 42. This ensures that the label is secure and accurate is pressed. The angle through which the platen 46 swings is set so that the underside 49 of the Pressure crucible in the dispensing or rest position shown in FIGS. 1 and 3 by about 15 ° relative to the Horizontal is inclined downwards.
