Definitions
- the invention relates to a printing unit according to the preamble of claim 1.
- Such printing units are found in particular in price labeling devices and hand stamping use. In its basic They consist of several pressure belts or wheels, which are manually adjustable by means of an adjustment button, so that selectable print types are placed in the print position can. After inking up in the printing position printing types with ink, which is usually indicated by a Ink roller or ink pad can be printed on an item - especially a price label - printed on it become.
- a ribbon printing unit is, for example, from EP 153651 A became known.
- DE 2604745 A discloses a hand stamp in which between Adjacent washers inserted between adjacent pressure tapes are that define a distance between two printing tapes.
- a disadvantage is that the assembly of the printing units is relatively complex. A simultaneous insertion of all Printing tapes in the printing unit is not conceivable, since between each two spacers a spacer is to be inserted, see above that a production only manually or through complex machines is possible. The printing units are thus due to manufacturing technology Problems relatively expensive.
- the object of the present invention is a To create printing unit, the printing ribbons easily adjustable are, and that is easy and inexpensive to manufacture.
- a printing unit with a Housing several type carriers arranged side by side in the housing, which are individually adjustable and have print types, and at least one between two adjacent type carriers positionable spacer solved in that the spacer between a first position in which it is not positioned between the type carriers, and a second Position in which it is positioned between the type carriers, is movable.
- the main idea is to make the spacer movable, in particular pivotable or also displaceable, in the housing the printing unit.
- the spacer is from its first Position (rest position in which the assembly of the type carrier is not hindered) in his second position (working position) spent in the it between two neighboring type bearers intervenes, and in which it is assigned the friction between the neighboring type holders by producing the necessary Distance between them is reduced.
- the advantages of the invention are primarily that Friction between adjacent type carriers against one Printing unit without spacers is reduced, so that the Adjusting the type carrier required forces also reduced are.
- the manufacturing effort is compared to that State of the art, in the washers between the type carriers are much less.
- the spacer be form-fitting to attach on a rotatable axis, so that it through Rotation of the axis between its first and second position is pivotable.
- Such an axis is particularly advantageous if several spacing elements are spaced apart a common axis are arranged, and each spacer by rotating the axis to a second position can be spent in between two neighboring type holders is arranged. This allows multiple spacer elements are simultaneously placed in their second (work) position, what the manufacturing effort for printing units with more than reduced two type carriers.
- the type carriers can be special, the coaxial printing tapes Wrap arranged adjustment wheels at least partially.
- the spacer is arranged in the vicinity of the setting wheels and preferably also engages between adjacent dials.
- An advantage here is that the friction between the neighboring dials during the setting process is, so that easier adjustability is advantageous Episode is. It should be noted that in the context of the invention It is also conceivable to use wheels as type carriers is; then the spacer would be between neighboring ones Engage pressure or setting wheels.
- the printing unit 10 shown in FIG. 1 contains one out of two Housing halves 12 and 14 composite printing unit housing, in which several arranged in parallel to adjustment wheels 16 and Deflection wheels 18 guided around the pressure range 20 are accommodated.
- the printing unit 10 is in particular for use provided in hand labeling devices.
- the print ribbons 20 are not included in Figure 1 for reasons of clarity shown, but clearly visible in Figure 2.
- the printing tapes 20 alternately carry printing types on their outer peripheral surface 22 and display types 24.
- the assignment of print types 22 to the Display types 24 are made such that print types 22, which are currently in the printing position on a deflection wheel 18, and display types 24, which are indicated by a on the top of the housing arranged window 26 are visible, in each case the same Number, the same letter or the like. This means that through the window 26 on the top of the housing through it can be seen which character with the below print types 22 located on the deflection edge onto a recording medium can be printed.
- the print bands 20 are around dials 16 guided around, which are rotatably mounted on a sleeve 28.
- the sectional drawing of Figure 2 shows that in the sleeve 28th three slots are attached to the right in Figure 1 lying sleeve ends are open. Reach through these slots Teeth 32,34,36 through which are attached to an adjusting shaft 42 are.
- the adjusting shaft 42 is in a bushing 44 slidably mounted in the housing half 14.
- an operating button 48 attached, with the help of the Adjustment shaft 42 axially shifted on the one hand and on the other hand can be rotated. Due to the axial displacement of the adjusting shaft 42 are the teeth 36 attached to it initially with the recesses 46 of an adjusting wheel 16 to be adjusted Engaged, and by rotating the adjusting shaft 42nd then, the printing tape 20 passed around its outer circumference until a desired print type 22 in Printing position is located below the deflection wheel 18. As before The respective position of the print types can be mentioned 22 checked through the window 26 attached to the top of the housing become. To achieve a drive connection between the pressure bands 20 and the setting wheels 16 have the pressure bands 20 teeth 50 on their inner surface, which in recesses 52 engage in the outer peripheral surfaces of the dials 16.
- This Latching mechanism includes a sleeve 28 attached Locking finger 54, which is on the inner surface of the sleeve radially inwards protrudes and engages in recesses 56 which are in one area introduced the outer peripheral surface of the adjusting shaft 42 are.
- a locking recess 56 is provided for each of the setting wheels mounted on the sleeve 28 16.
- the adjusting shaft 42 extends in the section immediately adjacent to the operating button 48 through a bushing 44 on a conical cap 64 is attached.
- a conical cap 64 is attached.
- One of the functions of this cap 64 is for a smooth covering of the upper part of the printing unit 10 to worry about.
- it also carries a window 26 surrounding it Frame 27, which is slidably mounted on the top of the housing is; the type of storage is clearly shown in Figure 2.
- Another locking mechanism for the dials 16 exists from a coil spring 66 which is parallel to the longitudinal axis of the Adjusting shaft 42 is arranged on the circumference of the adjusting wheels 16 is that they are in the recesses 52 on the circumference of the dials 16 partially penetrates, which can be clearly seen in Figure 2 is. So that the dials 16 can be rotated, though the screw spring 66 engages in its recesses according to FIG. 2, is the coil spring on an elastically compliant Pad 68 stored. When turning the setting wheels 16 can dodge the coil spring 66 in this way and thereby press into the cushion 68.
- the deflection wheels 18 are rotatably mounted on an axis 70, which extends parallel to the longitudinal axis of the setting shaft 42. Another locking mechanism works with the deflection wheels 74 together, the deflection wheel in a manner known per se 18 locked in a position in which a printing type 22 is in the printing position.
- FIG. 2 it can be seen that a second printing unit 72, which with the printing unit shown on the left in FIG. 2 essentially is the same, but has smaller print types 22 ', in the Housing 10 is installed.
- Printing unit spacer elements 80 are provided between two positions adjustable are:
- the spacer elements In the second position are the spacer elements with the reference symbol 80 marked. They are between two adjacent printing tapes 20 and their tip is between the Positioning wheels 18 positioned over which the printing tapes 20th run.
- the spacers 80 thus prevent in the second position a touch of adjacent pressure tapes 20, which increases the friction significantly reduced between them and an easier setting enables the pressure tapes with the actuating button 48.
- the first position is primarily from manufacturing Reasons, because it allows the printing tapes 20 at the same time, ie (directly next to each other with respect to FIG. 1) to bring into the housing of the printing unit 10. Subsequently the spacer elements from position 80 by pivoting in position 80 ', in which the distance between define adjacent print bands.
- the second printing unit 72 Since the second printing unit 72 has significantly smaller printing types 22 ' and thus has thinner pressure bands 20 ', is the friction less between the latter, so that spacer elements are dispensed with can be.
- the spacer elements are common are arranged on an axis 82 and by (cylindrical) Spacers 84 are kept apart from each other.
- the axis 82 has a provided square cross-section, while the spacer elements 80 equipped with a hole 86 with two straight side surfaces are so that the spacer elements 80 in the form and are torque-locked on the axis 82 because the Axis 82 extends through hole 86.
- the spacer elements 80 are roughly rectangular and point near one of the shorter ones Open hole 86.
- Figure 4 shows the view of a spacer element 80. It is in its end region opposite the hole 86 is trapezoidal shaped. The distance from hole 86 and that at the top left in FIG. 4 drawn corner is slightly larger than the distance between Hole 86 and the corner of the Spacer 80.
- the shape of the spacer 80 is chosen so that a rotation in the printing unit 10 between the first and the second position is possible - that's why it's on his drawn in on the right in Figure 4, the hole 86 adjacent Rounded side so that no collision with the top Wall of the housing of the printing unit 10 occurs - and that one perfect separation of the adjacent pressure tapes 20 and setting wheels 18 is achieved, to which the trapezoidal shape contributes.
- the result is a printing unit, especially with relative large print types that are easy to use and characterized by simple manufacturing.
