The invention relates to a hand-labeling apparatus of the kind set forth in claim 1.

For example, from United States Patent 3,265,553, a labeling apparatus of the aforementioned kind is known, which apparatus has a transporth wheel with radially extending pins, which crane port wheel is driven from a one-way one-way coupling, which in turn is driven by the unified weight bar. In one embodiment of the apparatus according to the aforementioned patent, there is a counter-pressure roller, which, however, serves only to hold the carrier belt against the transport wheel.

known

Ted this and other / hand-labeling apparatus of the kind in question, each time the pivot of the control arm advances, the label tape is fed a taped stretch so that a new label appears at the outlet, and the label tape advance occurs by turning the conveyor wheel which includes the perforated tape alone. by means of the pins engaging in perforation holes in the label tape, thereby pushing the tape forward. The swinging of the control arm is usually carried out in a rigorous manner, so that relatively high speeds of rotation of the transport wheel and especially very high hedge accelerations are achieved. As a result, at each swing of the operating arm, the belt is also rapidly accelerated and advanced at high speed, so that the forces transmitted by the pins on the perforation holes from the transport wheel are disproportionate, which frequently causes the perforate holes to tear up. This results in feed disturbances which may cause incorrect preparation of the labels at the outlet and, when the labels are to be printed, to an inaccurate application of the pressure, and in many cases even to a complete failure of the apparatus, so that it is necessary to manually pull the tape and re-insert this into the appliance.

The labeling apparatus according to the invention is peculiar to the design according to the characterizing part of claim 1, which has several significant advantages.

Thus, the movement of the transport wheel by means of a latch of the specified kind results in the advantage that, due to the engagement of the latch with its pins, the transport wheel is still rotated at exactly the same angle and partly the advantage that the latch is fixed at the correct setting with its front edge. presses against the circumference of the transport wheel so that the label tape is firmly clamped between the latch and the transport wheel. As a result, the driving forces are transmitted to the tape over its entire width, thereby eliminating the tear of the label tape. This avoids all the disruptions caused by the prior art hand-labeling apparatus caused by the use of the label tape.

To ensure that the latch does not cause damage to the tape when the arm with the latch returns to its initial position after a feeding operation, the invention may be further embodied as set forth in claim 2. Although during the return of the arm with the latch to the initial position, it may be advantageous if, according to the invention, the design is as claimed in claim 5, whereby it is possible always to keep the label tape under a certain tension.

In the apparatus of the present invention, the operating arm is pivotal about an axis at the rear end of the apparatus, and at the same time, in the design according to the invention, the supporting arm of the latch should extend rearwardly for the axis of the transport wheel. Therefore, according to the invention, it may be advantageous if the configuration is furthermore as stated in claim 4 wherein the support arm is only oscillated indirectly by the operating arm, but that only small frictions occur, so that the support arm and thus the latch can ensure a smooth oscillation movement. thereby assuring that the swing of the carrier arm is always fully accomplished, thereby further ensuring the exact feed length of the label tape.

3 141111

With the previously known labeling apparatus, the labeling of the label tape takes place only during part of the movement of the operating arm and usually only under the arms return to its initial position. Therefore, it is for the future! Keeping the tape at the available time provided briefly. However, the design according to the invention means that this time can be extended and the influence on the label tape during the feeding is further reduced, namely if the forward movement of the control arm is used as a back movement to advance the tape. For this purpose, the design according to the invention can also be as set out in claim 5. During the swinging of the operating arm, the rocker arm is also pivoted, thereby increasing the distance between the outlet and the transport wheel, so that the belt is pulled further along the outlet during the swinging of the rocker arm. During return of the control arm to its initial position, the rocker arm also returns to its initial position, thereby reducing the distance between the outlet and the transport wheel, while simultaneously turning the transport wheel to retract the label tape. As a result, the label belt is advanced at a slower speed beyond the outlet than corresponding to the movement of the transport wheel, which results in a further reduction of the load on the belt, which also helps to ensure a very accurate feed length.

In addition, according to the invention, the configuration may be as set out in claim 6. In this way, not only is a very simple construction, but also the further essential advantage that the outlet is resilient at the front end of the rocker, so that the conveying effects, the carrier belt is exposed to during the transfer of the label to the object to be labeled is greatly diminished.

The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 is a longitudinal section through an embodiment of the invention; and FIG. 2 shows a simplicity of the embodiment of FIG. 1, indicated by an arrow IT in FIG. 1, Bet on a dry scale.

The apparatus shown at the rear end has a hollow handle 1, with which a control arm 3 is pivotally connected by means of a bolt 2, which at its front end engages in the end of the apparatus housing 4 a layer hole 5 * which is open at the arm the leading edge, and in which engages a bolt 6 which interconnects two identical arms to form a rocker arm 7 "which is pivotally mounted about a bolt 8. The distance between the rocker arm 7 *" two side arms is somewhat larger than the widest label band useful in the apparatus. The handle 1 is formed as part of a side wall constituting the base plate 9 of the apparatus housing, in which the bolt 8 is fixed. The second side wall of the apparatus housing 4 is constituted by a corresponding plate, not shown in parallel with the plate 9, which, after mounting the individual parts of the apparatus, is permanently fastened to the apparatus by means of cladding plates 50 and spacer bolts not shown.

In the rocker arm 7 * closest to the handle 11 of the handle 3 is formed a 4 1A1 111 long hole 51 through which extends a hollow 52 which is fixed to an angle piece 55. Also this angle piece "consists of two spaced apart flat punches The angle piece 53 is pivotally mounted about a bolt 54 secured in the housing and carries a latch 55 · Between the angle plate 53ts two plate-shaped parts there is about the bolt 54 pivotally mounted a feed wheel 56 »having radially protruding pins 28. The circumference of the transport wheel 56 * may be provided with a coating with high surface friction, but may also comprise a metal wheel with a ribbed circumference.

A spring 57 inserted between the bolt 6 and the bolt 14 retains the rocker arm 7 in the stream of FIG. 1. A label tape roll 35 is. inserted in the apparatus, removably mounted in bearings not shown in the two side walls 9- Separation plates 58 and 59 limit it to occupy the space of the roll 33. The roller is located almost completely inside the apparatus, whose side parts at the top have rectilinear restrictions. Therefore, no special measures are required to remove the roller 33 · The label tape consists of a carrier belt 29 on which square labels 31 are detachably disposed without spacing. On the forward portion 12 of the rocker arm 71 s, near the free end of the rocker arm 7 *, a printing plate 12 is attached, and the label strip 29 extends, in the illustrated embodiment, a roller 60 rotatably mounted around the bolt 8 to the leading edge 15 and from there Directly to the circumference of the feed hole 56 * s, the radial pins 28 of the wheel engaging in perforation holes in the carrier 29 · Near the forward end of the rocker arm 71 s, it carries on each side an upwardly extending arm 18, which two arms carry a bearing bolt at their free ends. 48, which constitutes a pivot bearing for two outside of each side of the pivot arm 7, placed on the pivot arms 19, pivotable angles 19, between whose free ends are rotatably mounted a color roller 20, as in the embodiment shown in FIG. 1 rests on printing types in an unspecified printing plant 22.

On the forward end of the rocker arm 7 *, which extends downwardly out of the housing, is a cam 61 of a resilient material. Between the printing plate 15 and the cam 61 are provided support elements 62 for the labels. The cam 61 has a proximal cylindrical tooth holder 63 which is secured between the side arms of the rocker arm 7 and four finger-shaped teeth 64 which extend in a resting position at an acute angle with the direction in which the belts move over the pressure plate 15.

If the control arm 3 is pressed downwards, the rocker arms 7 are pivoted in the clockwise direction and the angle piece 53 is also pivoted in this direction. Thereby, the latch 55 swings across a neighbor of the nearest radial pins 28.

During this movement, a resilient ratchet plate 65 retains the transport wheel 56. At the same time, the color roller 20 is moved over the printing types and positioned to the side of the printing unit 22. As the rocker arms 7 make a pivotal movement about the bolt 8, the loop formed by the label carrier belt 29 will thus be extended. at the end of the oscillation movement, a belt length is extracted from the supply roller 33 corresponding to a half feed step, without the feed wheel% moving. In this end position, a label 31 above the printing plate 15 is pressed against the types of the printing plant 22 * so that the label 31 is printed. The lever 3 is released, the spring 57 pivots the rocker arm 7 opposite the clockwise back to the output position. Thereby, the leading edge 66 of the latch 55 * abuts against the adjacent radial pin 28.

A spring 67 seeks to hold the latch 53 Fired so that in its resting position it does not press against the transport wheel 561 s perimeter. However, during the return movement, the leading edge 66 of the latch 55 * abuts against a pin 28, the latch 55 will pivot in a counterclockwise direction, and its leading edge will thereby press the belt toward the surface of the feed wheel 561 s, thereby clampingly holding on to it.

During the swing back of the swivel arm 71, the front label 31 * is further loosened at the outlet due to its stiffness as the belt 29 bends around the pressure plate 15 and the label then slides over the supporting members 62 and sits in advance by means of the printing unit 22 with a pressure. face up against teens 64 * s undersides. The label 31 still adheres with its rear end to the band 29 or to the support member 62. Through the spaces between the teeth 64, the leading edge of the label is clearly visible. The protruding front portion of the label 31 *, whose adhesive surface is on the underside facing away from the teeth 64, is now placed in the desired position on the object to be. is labeled, which is easily and accurately possible because the front edge 68 of the label is visible. Then, by moving the device backwards completely from the apparatus, the label is pulled out and pressed by the cam 61 * finger-shaped teeth 64 against the object to be labeled.

The front cover 69 of the device housing 4 is designed so that from above the front can be seen the label 31 ** 0 front edge between the teeth 64 of the cam 6l *

The FIG. 1, the angle of 7 ° between the line of sight 71 µg of the underside 72 of the apparatus corresponds in the illustrated embodiment to the nearest 80 °.
