Device for printing and coloring under constant pressure on hand-held labeling devices

The invention relates generally to a hand-held device for labeling or printing and outputting labels, wel- ■ ches in the following briefly referred to as Handetxketti er gerät will. In such a device, the labels guided on a carrier tape are printed with letters and numbers or labeled, which include price information or other information, what the printed labels on the surfaces for example, be attached to commercial goods. The invention relates in particular to a constant pressure inscription and inking device for a hand-held labeling device.

In a hand-held labeling device known per se, a hand lever is used printed in the direction of a handle and then an inking roller, which is brought into contact with the type surface of a print or stamp head, moved so that it rolls on it, until it leaves the stamp head. In the meantime, the

Print or stamp head for printing the labels with the same brought into action, with the labels on a pressure or counter plate.

With conventional hand-held labeling devices, this depends on the pressure or the However, the pressure exerted on the die head directly depends on the force with which the hand lever is applied and squeeze the handle. Thus it is often difficult to use the hand lever and the handle correctly Force to move relative to each other. As a result, the stamp imprints on the labels are very often indistinct when the force operating the hand lever is too weak.

To prevent this disadvantage, a construction has been proposed in which the hand lever is divided into two levers, between which a compression spring is arranged, to store the energy resulting from the actuation force, whereby the printing or labeling process "can take place under a predetermined pressure which is determined by the energy is. However, since such a proposal does not dispense with a special energy storage element, such as a compression spring can be, the construction and the manufacturing process are complicated, which increases the manufacturing cost. The required number of parts is namely increased and the need for the hand lever in two with recesses Dividing up separate hand levers provided with the compression spring contributes to the increase in manufacturing costs.

In the two constructions discussed above, the inking roller is always with the front of the printing or stamping head in contact, even during the actual printing or labeling process, creating a resistance or a

809840/0905

Inhibition of the operation of the hand lever is opposed, which makes a soft stamping or printing impossible process to achieve.

The invention thus primarily pursues the goal of a constant pressure labeling and inking device for to create a hand-held labeling machine, which of the disadvantages conventional hand-held labeling devices is free.

Another object of the invention is to provide a constant pressure lettering and to provide inking apparatus of the above type in which an inking roller from a pressure or Stamp head is moved when a pivotably mounted on the frame of the labeling device hand lever by a predetermined Angle is shifted, the port movement of the inking roller or roller under the action of an elastic member takes place, which is mounted between an inking roller holder holding the inking roller and the device frame, whereby the low actuation force required to carry out the labeling or stamping process for the hand lever easily and can be reliably felt.

Another object of the invention is to provide a constant pressure marking and inking of the above Tjrps at which the labeling or printing at any time clean, soft and immediately under a constant pressure durchgefü hr can be t.

Another object of the invention is to provide a constant pressure lettering and inking apparatus of the foregoing Way of creating in which on any energy storage device omitted in favor of a reduction in the number of individual parts and for the purpose of simplifying the construction is.

A return spring 7 is under compression between a retaining eyelet 5 arranged at the upper edge of the hand lever 3 and a retaining pin 6 at the rear end of the handle 2, the The spring is so tensioned at any time that it loads the hand lever 3 in such a way that it moves clockwise into a rest position or released open position rotates, as in Fig.1 shown. The front, i.e. the one in Pig. 1 left half of the hand lever 3 is designed as a fork head 8, which a print or stamp head 9 carries. The printing or stamping head 9 is on its underside with one or more Oiypeflachen 10 and has a curved surface 11 on its lower front corner. The print or stamp head 9 also has a raised portion 13 with a triangular cross-section ge st old, which is arranged slightly above the curved surface 11 on each of the side walls 12. Two protruding pins 14 are in the upper end portions the side walls 12 are provided. With the reference number 15 is a pressure or counter plate designated with the pressure or Stamp head 9 cooperates when printing or stamping labels that are on a continuous label strip 16 be introduced.

The reference numeral 18 denotes a gate feed roller, which by pressing or releasing the hand lever 3 and the Handle 2 is set in motion so that it rotates gradually and the label tape 16 from the roll holder 17 unrolls and the plate 15 feeds. The components described so far do not belong to the core of the invention, which is why on their Discussion in detail is dispensed with.

809840/0905

At the front end portion of the equipment frame 1 is a holder mounting 19 is provided on which a dye supply device 20 is attached, which is an essential part of the constant pressure labeling and inking device according to the invention represents. The fabric feed device 20 comprises an inking roller holder 23 in which two each other spaced oppositely arranged side plates 21 by means of a connecting plate 22 at their front upper edge portions are connected to each other. An inking roller 26 is between the lower end portions of the side plates 21 of the inking roller holder 23 rotatable with the aid of an axle 25 mounted, the axle 25 being provided with two flanges 24. Two coil springs 27 are between the side plates 21 of the inking roller holder 23 and the front upper end portions of the Eahmens 1 arranged.

Essentially in the central sections and in the transverse direction, i.e. both in the direction to the left and to the right in Fig. 1, the side plates 21, two pivot pins 28 are provided which are at a predetermined distance below the upper edges of the side plates 21 are arranged so that these side plates 21 are clockwise and counterclockwise the sides of the holder mounting 19 can swing. In the upper portions of the side plates 21 are above the pivot pins 28 two substantially arcuate slots 29 are provided, the center line of which is on an arc of a circle around the pivot pin 28 runs. An elongated axis 30 is with both of them Ends in the arcuate slots 29 received, so that these can lead to the pivoting movement of the inking roller holder 23. The axle 30 is secure in the upper end portion of the Holder mounting 19 held and received in both side walls of the device frame 1.

809840/0905

In the rear upper edge portions of the side plates x 21, two protrusions are formed which are directed rearward, i. to the right in Pig. 1 protrude over the side plates, making them with the protruding pins 14 of the printing or Stamp head 9 can cooperate. Incidentally, each of the coil springs 27 has its one end portion 27a on one of two retaining pins 27 protruding from the lower end portions of the side plates 21 while the other end portions 27b of the springs are attached to the corresponding end of the elongate axis 30. It should be underlined that the pivot pins 28, the retaining pins 32 and the axis 25 are arranged on a neutral line P. If the hand lever 3 is in its not pressed position or marriage, as in Pig. 1, the axis of the coil springs 27 is to the right, i.e. to the rear of the neutral one Line P is offset and the rear, i.e. right-hand end of the archers 29 is held on the elongated axis 30.

The mode of operation of the hand-held labeling device constructed in this way is described below. The hand lever 3 is in his normal marriage according to Pig. 1 printed, i.e. actuated, and counterclockwise around axis 4 against the spring force the return spring 7 and the coil springs 27 are rotated. Accordingly, the fork head 8 also rotates counterclockwise the axis 4 and the pressure or stamp head 9 moves in the opposite direction the action of the coil springs 27 downwards.

In the meantime, the puddles 24 of the inking roller 26 are detected by the downwardly moving stamp head 9 and the inking roller holder 23 is rotated clockwise about the pivot pin 28. The consequence of this is that the inking roller 26 to the front on the type surface 10 of the print or stamp head 9 unrolls, whereby the type area is supplied with dye.

809840/0905

At the same time, the elongated axis 30 is relatively in the Slots 29 of the inking roller holder 23 moved.

Under the conditions in which the elongated axis 30, like in Pig. 2, is located substantially in the middle of the slots 29, i.e., under operating conditions, at which the axis of the coil springs 27 with the neutral line P is aligned, the inking roller holder 23 is in a turnover position in which the loading forces exerted by the coil springs 27 are directed neither clockwise nor counterclockwise. This has the consequence that the operating force of the Hand lever 3 counteracting force is canceled, so that the hand lever 3 can be operated without it of the clockwise spring force of the springs 27 is applied.

If the hand lever 3 is from the operating state shown in FIG Turned slightly counterclockwise, the inking roller holder becomes 23 moved forward, i.e. to the left in Fig. 2, because the flanges 24 of the axle 25 with the raised portion 13 of the printing or stamping head 9 cooperate. Then the elongated axis 30 is relative to the front end portions the slots 29 are displaced and the axis of the spiral springs 27 is allowed to be the neutral line according to FIG. 3 P forward, i.e. to the left in Fig. 3. That has the consequence that the exerted by the coil springs 27 Kxätze no longer act counterclockwise, but clockwise and that the inking roller holder 23 under the action of their Direction of alignment changed forces is caused to rotate clockwise. It is thus possible for the hand lever 23 to approach the handle 2 under the operating force exerted on the hand lever. In this way, the Type area 10 of the print or stamp head 9 in contact with the placed on the counter plate present label, so that the

809840/0905

Printing or labeling process under the predetermined pressure can take place, which is determined by the minimum actuation force that has to be overcome when the inking roller holder 23 passes through the envelope position.

The front edge sections are also in this operating state the slots 29 of the inking roller holder 23 at the elongated axis 30 held so that the inking roller holder 23 can no longer turn clockwise. At the same time, the protruding pins 14 are in contact the rear edges of the projections 31 of the inking roller holder 23-

If the hand lever 3 is released in this state, it is pivoted back under the action of the return spring 7 in a clockwise direction. The printing or stamping head 9 is then accordingly moved upward by the counter plate 15 and the projections 31 of the inking roller holder 23 are moved in the direction of arrow A (Pig. 3), which by means of the protruding pins 14 of the printing or stamping head 9 takes place. This has the consequence that the inking roller holder 23 to one Rotation in the counterclockwise direction about the pivot pin 28 caused will. Is the axis of the coil springs 27 first over the neutral line P in Pig. 2, the forces exerted by the coil springs are reversed in direction and no longer work clockwise, but counterclockwise. The inking roller holder 23 is also counterclockwise rotated, the inking roller 26 rolls on the type surface 10 until the inking roller holder 23 in its Has returned to rest position. Finally, the rear end projections of the slots 29 are in engagement with the elongated one Axis 30 and take the inking roller holder 23 and the hand lever 3 their in Pig. 1 starting positions shown.

809840 / 09-5

Above has been "described that in the invention Constant pressure labeling and inking device at Pressing the hand lever in the direction of the handle the inking roller initially in contact with the print or stamp head below the action of the elastic members is loaded, which is arranged between the inking roller holder and the device frame are. If, however, the hand lever of the labeling device has been pivoted or pushed through a certain angle, it is the inking roller under the action of the same elastic Links are loaded in the opposite direction, causing the inking roller to move away from the print or stamp head.

The most important feature of the invention is thus that the inking roller in the first stage of the printing or labeling process represents an obstacle to the printing process and that when the print or stamp head over the envelope position (neutral line P) passes away, the inking roller is positively removed from the print or stamp head becomes, this being done under the action of the springs 27.-At this moment the said obstacle disappears instantly and the printing or stamping head hits the counterplate or the one to be labeled or printed Label surface with constant force. This enables printing or labeling under constant pressure. MLt help of the inventive design of a Hand labeling device is primarily achieved the advantage that for printing or writing on the label tape required minimum pushing or actuating force for the hand lever can be easily and reliably felt when the Inking roller leaves the print or stamp head, while at all times a clean, smooth and correct printing with constant pressure is guaranteed.

809840/0905

It should also be underlined that pressing or pressing Hand lever can be made smooth, while the smoothness and speed of the printing process is increased because the Inking roller during the printing or labeling process is arranged away from the print or stamp head.

Perner should be noted that the device according to the invention any special energy storage device can be dispensed with, which reduces the number of individual parts and simplifies the construction as a whole. This in turn facilitates the manufacturing process, which leads to mass production of the device.
