Description

Equipment for labeling CD discs

The invention relates to a device for labeling laser discs, comprising a support plate for placing labels, a label mandrel matching with the free inner diameter of the center hole of the label and protruding from the support plate, and a free inner diameter of the center hole of the CD matched with the label Guide lugs arranged concentrically with the mandrel, wherein the label mandrel and the guide lugs are connected to the carrier plate.

Such a device is known from Japanese patent publication HEI5-325495. The label mandrel is fixedly connected with the guide protrusion. With the CD placed, the guide projections are pressed down together with the label mandrel into contact with the label placed on the support plate with the adhesive side up. It is not clearly visible from above when the CD is in contact with the label. There is no reference quantity to which the amount of depression can be located when viewed by eye. In addition, the required shoulder configurations on the label mandrel or on the guide projections are not always favorable.

In addition, see German Utility Model 296 17 424 for prior art. In addition, see German utility model 295 21 471. The goal of German utility model 295 17 424 is similar to the well-known goal of the Japanese publication mentioned by mentioning, all is to provide a kind of guide projection or label mandrel to be guided evenly and advantageously on the whole depression stroke, and The object of utility model 295 21 471 is above all to implement a capture process. The guide protrusion and the label mandrel are combined in a single rod-shaped member with a guide curve at the lower end. By means of this guide curve, while the label previously placed on the carrier plate is centered, the separate component must be aligned with the carrier plate, ie inserted into the through-opening there during lowering and thus centered. Because in the construction of this device, when the CD is folded with the label, the CD also rests on a shoulder that is constructed and combined in said separate member, so the label is not visible. Here too, when viewed from above, it is not possible to discern how far the CD is in contact with the label when it is lowered. However at times this may be critical for reliable operation and correct application of labels.

Starting from the prior art cited first, the present invention aims at existing technical difficulties and improves the known equipment for labeling laser discs to make it easy to use.

This technical difficulty is first and foremost solved in the object of claim 1 , according to which the label mandrel is designed to move relative to the guide projection, which is stationary. Since the guide protrusion is fixed, when the label mandrel is depressed by means of the CD, a relative movement occurs between the guide protrusion and the label mandrel, and this relative movement can be used as a measure of the depression. Specifically, this dimension is given when the guide lug emerges from the CD. This amount of threading corresponds to the approach distance between the CD and the label that is just hidden by the CD when viewed from above. This enables advantageous and reliable labeling.

The object of the invention is also the apparatus for labeling compact discs described in the introduction, in which the label mandrel, which can be sunk against the spring force into the plane of the support plate for pressing down, is also provided with a cover.

Such a device is fully known by the submitted text of DE-GM 296 17 424. However, it is mentioned there that the guide projections protrude from the label mandrel by an amount which is equal to many times the thickness of the CD. Furthermore, this device works well and is easy to operate. However, although so far not proven in practice, the document argues that, due to the dimension of the radial projection of the CD relative to the label mandrel and guide projection, a leverage force is produced. With a corresponding eccentric load, this lever force tends to bring the CD into a skewed position relative to the guide projections before the CD is pressed down by means of the cover. Since the CD cannot continue to deflect after this, the possibility of some kind of damage cannot be ruled out in theory; especially at the same time that the downward elastic deflection due to this deflection will not be slight or very slight.

Proceeding from this, the invention also proposes that the dimension of the guide projection protruding from the label mandrel only roughly corresponds to the thickness of the CD. In this way, on the one hand, the CD remains unmistakably centered; on the other hand, the guide projections can continue to guide and center the cover provided for pressing down on the CD. At the same time, however, the CD jumps out of the device should the eccentric loads indicated above be possible. This measure can also be used in the embodiment described first, since this possibility is provided even for label mandrels that are movable relative to the guide projections.

The object of the present invention also includes a method of labeling CDs by means of a device having a label mandrel adapted to the free inner diameter of the central hole of the label and protruding from the support plate and a device for pressing down against a spring force. Caps for label mandrels that sink into the plane of the support plate.

Such a method is also known from the submitted text of DE-GM296 17 642. However, it is proposed there that the CD is first mounted on the guide projections and then sinks together with the guide projections when placed on the label mandrel. Therefore, the problem to be faced by the method of the present invention is to provide a method that can be easily implemented.

The first measure taken for this purpose is to first secure the CD to the cover and then press the cover with the CD down against the label mandrel until the CD comes into contact with the label. The invention proposes that the CD is no longer fixed and pressed down together with guide projections concentric with the label mandrel, but that the CD is fixed on the cover, and the cover together with the CD fixed on the cover overcomes the position of the label mandrel. The spring resistance presses down, whereby just contact is achieved between the label and the CD. Here too, self-centering is preferably formed between the CD fastened to the cover and the label centered by means of the label mandrel. Specifically, this can be achieved in different ways, as will be explained in more detail below. In addition, it is also preferable to clip a CD on the cover. For example, a jumpable fastening pin can be provided for this purpose, which snaps in easily by pressing the CD onto the cover (from below). As we all know, a CD is very light in weight, so a relatively small elastic force of the fixing pin should be sufficient. Particularly preferably, the fastening to the pressure cap takes place by means of a locking projection protruding downwards in the center of the pressure cap. However, the fastening to the pressure cap can also be achieved by means of locking projections protruding downwards at the edge. The locking protrusion on the edge exceeds the radial dimension of the CD. According to another suitable form, in this case a further latching projection or a fixed counter-stop is also provided on the opposite side.

In a further detail of one of the aforementioned embodiments, the invention also proposes that the label mandrel is constructed in several parts. If, firstly, the circular shape of the label mandrel's cross-section is advantageous in terms of providing a support surface, then a multi-part construction of the label mandrel is also advantageous for other reasons which will be explained further below. According to a further development of this rule, the label mandrel can in particular consist of at least two sub-label mandrels which complement each other circumferentially to form the label mandrel. In this case, it is advantageous if a carrier plate and webs of guide projections are provided between the two partial label mandrels. As a result, the guide projections can be connected directly to the support plate in the continuation of the plane of the support plate and thus to the fixed part of the device. If a cover is provided in the device, it is also provided in another configuration that the cover has a central opening. The inner diameter of this hole matches the outer diameter of the guide projection. Especially if the guide projection is designed to be stationary, the length of the central hole should be such that the protruding guide projection completely enters this hole when pressed down. Even if the hole is not a through hole, that is, a tube that is closed at one end (and protrudes from the upper side of the cover), the advantage that the pressing process can be judged by the size of the guide protrusion still exists; and it is advantageous that , as the amount of depression increases, the guide between the cover and the guide protrusion can be better guided. In addition, it is also designed that the cover has a hole and possibly an edge protruding upwards but leaving the hole open, from which the protrusion of the guide projection can be seen. This configuration is particularly advantageous for the continuous visual determination of the depression stroke described in the introduction. In this respect, however, the last described embodiment is not restricted, and graduations, for example, can also be provided on the stationary guide projections. Instead of producing by injection molding, it is also possible to provide a foam structure made of elastically restoring foam. Such a foam material can also be used instead of a spring to support a corresponding (injection-molded) tank. As far as the label mandrel is concerned, it is also proposed in a further embodiment to design it as an elastic part which is integral with the carrier plate. The required elasticity of the label mandrel, especially when produced by injection molding, can be obtained by the material properties of the label mandrel itself. In a further embodiment, the basic structure with regard to the separate configuration of the guide projection and the label spindle and all the embodiments described further therefor also provide for a gap to be provided between the guide projection and the label spindle. On the one hand, this configuration facilitates the placement of the CD on the label mandrel or on the upper shoulder of the label mandrel; on the other hand, this clearance also forms a suitable protection for the structures associated with the free inner diameter of the CD.

The stated possibility of achieving the required depression of the label mandrel can also be supplemented by a leaf spring instead of the known helical spring (see submission DE-GM 296 17 424), which is located on the label mandrel The underside is arranged in a cross therewith. Especially in the object by GM 196 17 424, setting such a leaf spring replacing the pressure spring 20 described there should have its own independent significance within the scope of the present invention. The disclosed content of DE-GM 296 17 424 is also fully included in the description of the application, and the features of this utility model are also suitably incorporated in the claims of the application.

With regard to other details of the spring construction with leaf springs, the disk 35 described in the mentioned utility model can be omitted without necessity. The ends of the transversely tensioned leaf springs are fixed to the outer cylindrical wall of the device.

A further advantageous embodiment of the invention also provides that the guide projections are designed as projections adapted to the outer diameter of the CD. In this case it is also advantageous if the guide projections are immobilized. At the same time it is also possible to construct the label mandrel as a closed can with an upwardly extending can bottom providing a support surface for the central region of the CD. In this case, the guide projection can be designed, for example, as a ring-shaped wall segment. A plurality of annular wall sections distributed along the circumference can be provided, which at the same time allow easy loading of the CD, since one can insert one's hand into the gaps between the wall sections.

For the embodiment described here in which the CD is fastened to the cover or pressure cover, it is important that the CD is centered relative to the label on the carrier plate 3 by means of the label mandrel. Specifically, by having the label mandrel have a central guide, in particular a hole, in which the fastening projection for the CD, which is formed in the center of the pressure cap, is guided. That is to say a guide chain or mating chain is realized, whereby first the label mandrel is guided centrally relative to the carrier plate, and then the pressure cap is guided centrally in the label mandrel by means of the fastening lugs.

Referring first to FIG. 1, an apparatus 1 for labeling a compact disc 2 will be described. The device 1 has a support plate 3 on which a label 4 can be placed with the adhesive side facing up, it is here only drawn as floating above the support plate 3 for the sake of clarity. The support plate 3 is centrally provided with a mandrel 6 which passes through a central hole 12 of the support plate 3 and protrudes from the support plate 3 appropriately. The outer diameter of the label mandrel 6 matches the inner diameter of the label 4 . In addition, the guide projection 9 is configured concentrically with the label mandrel 6, and its outer diameter matches the free inner diameter of the CD 2. The label mandrel 6 and the guide protrusion 9 are respectively fixed on the device 1 . In this embodiment, the guide projection 9 is fastened in a base plate 10 which itself is secured by a ring-shaped flange 11 protruding downwards from the support plate 3 and substantially matching the outer diameter of the label mandrel 6 . The label mandrel 6 can overcome the elastic force of the spring 7 and move relative to the fixed guide protrusion 9 . The label mandrel 6 configured here as a ring is pressed down by the CD or the cover 13 by means of the CD 2 during use until the shoulder surface 8 is substantially aligned with the surface of the support plate 3 in a plane.

In particular the cover 13 has a central guide pin 14 which can be inserted into a pin hole 15 of the cylindrical guide projection 9 in this exemplary embodiment. Between guide pin 14 and wall 17 of cover 13 , guide pin 14 is formed with an annular space 16 corresponding at least to wall thickness S of guide projection 9 . The wall 17 is likewise cylindrical and has an upper roof 18 . Overall, the wall 17 forms the grip section of the cover 13 . A double inner and outer guidance is provided by means of the pin 14 and the annular space 16 . The guide surfaces that will come into contact with each other increase in size as the amount of depression increases.

It is also significant that a step 19 is formed on the support plate 3 on the radially outer side (see in particular FIG. 3 ). The radius R of step 19 is smaller than the radius R of CD 2. Therefore, in the state after pressing down, leave space between CD 2 outer edge and support plate 3. In the embodiment of FIG. 3, this distance is utilized to form a catch bead 20 (see FIG. 3). They first allow for example CD 2 and cover 13 to be snapped together, cover 13 and the CD 2 of snap-in connection are then inserted in the hole 15 of guide projection 9 by means of pin 14 and thus realize the centering of label.

The construction of the device according to one of the embodiments of FIGS. 1 to 3 can be seen in more detail from the perspective view shown in FIG. 4 . In a further variant here it is provided that the outer wall of the label mandrel 6 is designed as a complete cylinder. The fixing of the label mandrel 6 relative to the base 10 or on the entire device 1 is here achieved by means of snap-in tabs 32 . On the end face of the locking tab 32 there is a guide surface 33 inclined downwards, so that during assembly it is elastically bent outwards to spring back a locking step 34 protruding inside the cylinder formed by the label mandrel 6 superior.

The embodiments shown in Figures 5 to 7 provide substantially the same structure, but have the following features.

In the embodiments of FIGS. 1 to 3, the label mandrel 6 is configured in one piece and in the form of a ring, whereas in the embodiments of FIGS. A sub-label mandrel 6'. The guide projections 9 ′ can likewise be formed in one piece with the carrier plate 3 , with webs 21 remaining between the partial label mandrels 6 ′ in the circumferential direction, which connect the guide projections 9 ′ to the support plate 3 . Furthermore, the label mandrel 6 or, in the exemplary embodiment shown in FIGS. 5 to 7 , the partial label mandrel 6 ′ is at a distance a radially inside from the cylindrical outer surface of the guide projection 9 ′. This leaves a circular ring connected to the carrier plate 3 via the web 21 , which means that there is a gap between the guide projection 9 or 9 ′ and the label mandrel 6 ′. Obviously, if the configuration of the guide projections 9 according to the embodiment of FIGS. 1 to 3 is selected, this recess can also be formed even when using a circularly closed label mandrel 6 .

FIG. 7 shows the bridging of the guide projections 9 ′ in the embodiment shown in FIGS. 5 to 7 .

The embodiment shown in FIGS. 8 to 10 corresponds to the embodiment shown in FIGS. 5 to 7 with the difference that here too the label mandrel 6 or partial label mandrel 6 ′ is formed directly in one piece with the carrier plate 3 . This configuration is shown in the die casting diagram of FIG. 10 . The sub-label mandrel 6 ′ is formed on the annular body 22 in a flap shape. As already explained with reference to FIG. 6 , the annular body 22 is formed due to the distance a. Based on the die-casting diagram shown, under the locking position according to Fig. 8, the pre-tensioning force given by the material is generated to pre-tighten the position shown in Fig. 8, so after the labeling process is completed, the elastic force makes the sub-labeling mandrel 6' rebound. More specifically, the sub-label mandrel 6' is connected on the radially inner side near the guide projection 9 by means of a hinge shaft formed by die-casting technology, and can move freely on the radially outer side.

In addition, the opposite configuration is also possible, ie the hinge axis is on the radial outside, while the valve is free to move on the radial inside. This configuration is even more advantageous, since no relative movement occurs between the edge of the label bore and the label mandrel when pressing down.

The feature of the sub-label mandrels constructed in the embodiment shown in FIGS. 9-11 is that they are constructed on one of the two parts of the support plate 3 or the pressure cover 13 as a whole and can be snapped open in the vertical direction. Housing segments which are integrally connected with the associated housing parts. The expandable housing segments preferably have a radial extent from radially inner to radially outer. Here, the springable housing segments are all connected radially on the inside to the associated part. They form the cantilever ends radially on the outside.

The embodiment shown in FIG. 11 corresponds to the embodiment shown in FIG. 8 . Here, however, the guide projection 9 has no inner bore 23 . The cover 13 therefore has only one bore 24 which is adapted to the cylindrical shape of the guide projection 9 .

An alternative support edge 25 is also shown in the embodiments shown in FIGS. 5 to 11 (in principle all embodiments are possible). The outer diameter of support edge 25 is obviously smaller than the outer diameter of CD 2, so also have the advantage of the step described for Fig. 3 in principle in this embodiment.

In the embodiment shown in FIGS. 12 and 13 , a guide bead 9 ″ is formed from a plurality of individual guide bead 9 ″.

Here, guide protrusion 9 " matches the radius R of CD 2, that is to say the inner surface 26 of guide protrusion 9 " is located at radius R ', and radius R ' is actually equal to or only slightly greater than radius R. It can be seen from the figure that the inner surface 26 is also configured in the shape of a cylindrical segment. Furthermore, in this embodiment, the sub-guide projections 9 ″ are configured integrally with the support plate 3 .

This configuration should also be explained as follows, that is, the support plate 3 is configured as a tank bottom and has a tank wall surrounding the edge of the tank bottom (that is, the guide projection 9 ″). The tank wall is configured correspondingly interrupted, between two The space between the can wall sections 9" is used to facilitate the insertion or removal of CDs. In order to form the two opposing recesses, two tank wall sections 9'' are formed.

Furthermore, a label mandrel 6" is formed which is not passed through by the guide projection 9". In this exemplary embodiment, the label mandrel 6 ″ is pot-shaped and has a continuous, round and planar end face (can base) 27 .

In addition, a modified cover 13' is provided, the lower support surface 28 of which is substantially continuous. Here, however, it can also be provided, as described for FIG. 14 , that the underside of the cover 13 or 13 ′ be provided with pressure-enhancing ribs 29 . Specifically, the pressure enhancing ribs 29 are a plurality of ribs extending radially relative to the centerline of the pressure cover. They are in a position overlapping the end face 8 of the label mandrel 6 . Each radially extending rib is bounded radially on the outside by a continuous annular rib.

Furthermore, the cover 13' has a radius corresponding to the radius R, so that the cover 13' can also be placed on the CD guided by the guide projections 9" and the CD can be pressed down for the labeling process.

As can be seen from Fig. 13, there are two guide protrusions 9 "in total. The opening between the guide protrusions 9" along the circumference can be convenient for putting into CD 2.

In the exemplary embodiment shown in FIG. 14, a guide projection 9''' formed integrally with the label mandrel 6''' is formed. Important is that the step height h of guide protrusion 9'' matches the thickness d of CD 2. In the embodiment shown in FIG. 14, the step height h is approximately equal to twice the thickness d of the CD 2. However, it can also be approximately equal to twice the thickness d. The reason why in this embodiment the step height h is only chosen to be substantially equal to twice d is that a pressure-enhancing rib 29 of a thickness of substantially one d is formed on the underside of the cover 13".

In addition, it is important to have a central groove 30 on the inside of the guide projection 9'', which cooperates with a corresponding centering pin 31 on the cover 13". In this embodiment, this groove 30 and the centering pin 31 are respectively Conical in shape.

15 and 16 show an alternative embodiment of the cover, which, incidentally, can in principle be combined with all embodiments of the device described above.

In this embodiment, it is first of all important that a projection 35 extending downwards and beyond a CD fastened to the cover is formed on the cover 13'' on the radially outer side. They can be used, for example, to protect CDs that have been fastened to the cover. Such an embodiment here also makes sense, for example, for covers according to FIGS. 19 , 21 or 24 , where a central centering securing projection is also formed. However, a cover according to FIG. 15 can still be provided here, wherein a cover base 37 with such a radial extent is formed that it encloses the CD and prevents it from being fastened just laterally by the projection 35 protruding downwards. The CD on the cover is damaged.

The particular feature of the cover 13''' in the embodiment shown in FIGS. For this purpose, as can be seen from the top view of FIG. 16 , the pressure fixing projection 35 is connected in this exemplary embodiment to the actuating projection 36 in order to form a one-piece structure. The manipulation protrusion 36 extends vertically upward relative to the cover bottom 37 . The manipulation projection 36 is connected to the pressure fixing projection 35 via a connecting arm 37 . The connecting arm 37 is connected by means of a connecting spring 38 integrally formed with the cover 13'' by injection molding. Furthermore, a certain cutout 39 is formed in this region of the cover bottom 37 . The cutout 39 passes through the connection spring 38 only.

Furthermore, the connecting springs 38 are designed in such a way that they essentially only allow a radially inward movement of the actuating projection 36 and the pressure fixing projection 35 .

It can also be seen from the figure that the actuating projection 36 is formed in the region of the fastening pin 40 . However, the actuating projection 36 (when not actuated) is not integral with the outer circumference of the fixing pin 40 , but protrudes radially from the fixing pin 40 by a dimension m. If a CD is caught now, then by pressing the manipulation projection 36 and the fixing pin 40 together, under the situation of the manipulation projection 36 and thus the pressure fixing projection 35 moving radially inwards, a radial movement can be achieved. Clamp CD 2 in place. In addition, a counterstop 41 is formed at the opposite location, which protrudes downwards from the cover plate 37 corresponding to the pressure fixing projection 35 .

The pressure fixing projection 41 can also be realized in the same way, alternatively or additionally, by a counter-fixing projection 42 protruding downwards from the cover base 37 . Of course, the opposite fixing protrusion 42 only needs to have a thickness consistent with the CD thickness. Furthermore, fastening pins can also be formed on the cover bottom 37 according to one of the other embodiments described above.

In particular in this embodiment it is also possible to completely dispense with the guide projections. For example, based on a design similar to that of the pin 14 , it can have an outer diameter directly identical to the inner diameter of the label mandrel 6 . As far as FIG. 1 is concerned, the guide projection 9 can be omitted without replacement.

In the device shown in FIG. 17 an alternative cover 43 is provided, which has a combined lower snap-in fastening 44 . What is important is that, as can also be seen from the top view of FIG. 18 , the latching securing device 44 is positioned in its latching position in the unactuated state. When manipulating or CD 2 is placed on the cover 43, the catch section 45 that the upper side stretches out from the cover 43 moves toward the center of the cover 43 or toward the stationary catch section 46. Visible from the top view of FIG. 18, but further details can also be seen in conjunction with the bottom view of FIG. Connect with cover 43.

This locking fixture is made up of a flange 49 matching with the CD 2 inner diameter and a locking fixture 50 protruding downward from the flange 49. In this embodiment, the cross-section of the clamping and fixing device 50 is convex and curved. After passing the apex of the curve, a pushing effect is produced by the upper curve in the direction of the cover 43 . When the clamping fixture 50 is relaxed, it continues to push the CD 2 upwards. The curve on the lower inlet side facilitates insertion into the inner hole 51 of the label mandrel 6 . As can be seen from the figure, the outer diameter of the clamping fixture 50 at the maximum diameter is greater than the inner diameter of the CD 2.

Furthermore, with regard to the device, one of the above-mentioned embodiments can be used. In particular, an integrally elastic label mandrel 6 can also be formed in a variant of the illustrated embodiment.

It is also not necessarily required that the snap-in fastening device 50 is guided in the bore 51 of the label mandrel 6 . The bore 51 can also be correspondingly larger than the (largest) outer diameter of the snap-in fixture 50 . It must exceed the diameter of CD 2 when cover 43 is constructed with this radially extending section, and cover 43 for example can be guided on the guide projection 9 ' that is constructed in the equipment by Fig. 12. Here also can cause a plurality of guiding contacts between the radially protruding part of cover 43 and the protrusion 9 ". Then no longer need to guide CD 2 on the protrusion 9 " of this embodiment, but only need Guide the cover on which the CD 2 is centered.

Shown in the embodiment shown in Figure 20 is how CD 2 is introduced by clamping fixture 50, to reach the fixed position shown in Figure 17.

The bottom view in Fig. 20 shows the cover 43 without the CD 2, that is, in a relaxed state. One of the clamping and fixing protrusions 50' can be configured with a larger width (larger circumferential length), while the other clamping and fixing protrusion (movable locking protrusion) 50" can be configured with a smaller circumference. to length.

In this embodiment, although not absolutely necessary, pressure-enhancing ribs 29 are provided on the underside of cover 43 . The contact between CD 2 and cover 43 is bounded by the underside of pressure enhancing rib 29. Specifically, an annular outer pressure-enhancing rib 29 is constructed, and its radius from the centerline of the cover 43 (or the centerline of the CD 2 hole) is substantially equal to the diameter of the label mandrel 6 (in the embodiment shown in FIG. greater than this diameter). Furthermore, this pressure enhancing rib 29 is positioned in an unillustrated central medial region of the CD. Starting from the annular outer pressure strengthening rib 29, there are pressure strengthening sub-ribs 29' extending radially inwards. As shown in the figure, their inner dimensions are substantially equal to the inner diameter of CD 2.

In the embodiment shown in FIG. 21 it is significant that the guide projection 52 is designed as a hollow body. More specifically, the guide projection 52 has a wall section 52' which is springable transversely to the longitudinal axis L. As shown in FIG.

In this embodiment, the guide protrusion 52 is composed of arc segments extending longitudinally one by one. These arc segments are separated from each other by slot-like holes 53 which also extend in the longitudinal direction. It can be seen that the grooves 53 are discontinuous and terminate at the upper and lower ends in the also cylindrical wall region of the guide projection 52 .

The wall is generally cylindrical in shape.

It is also significant that the mentioned arc or wall section 52' is curved outwards. Since the material is of spring-elastic construction, for example a plastic die-cast part, the CD can be pushed in, during which the wall section 52' moves slightly inwards. After the CD is pushed on as shown in FIG. 21 , a snap-in fastening is thus formed.

In this embodiment, the outer diameter of the guide projection 52 (given the possibility of deflection in the radial direction) is slightly larger than the inner diameter of the associated CD hole.

It is also significant that, as can be seen in particular from FIG. 22 , the label mandrel 54 has a nose 55 . This is particularly meaningful especially when the device works in combination with a label, such as the device known from German utility model document 296 19 143.4. The document contents of this utility model are all included in the description of the present invention, and the features of this utility model are also suitably absorbed in the claims of this application.

Furthermore, as can be seen from the cross-sectional view shown in FIG. 21 , the outside of the label mandrel 54 is a continuous cylindrical wall 56 . A through hole is formed on the inside at the bottom of the hole 51 . The fixing support 57 of the bottom part 58 is inserted into the hole 51 . A fixing element 60 that exceeds the diameter of the hole 59 is provided on the upper side of the fixing support 57 . The label spindle 54 is thereby only prevented from further upward movement, for example due to the force of the spring 61 .

During manipulation, the end edge 52 " of the guide projection 52 is inserted into the hole 51 up to the mandrel section 51 '. It is also particularly preferred here that the free length a of the guide projection 52 is greater than that of the guide projection when the CD 2 is fixed. The insertion depth b of the riser 52 in the hole 51.

When the guide protrusion 52 was inserted in the label mandrel 54, the guide protrusion 52 had such a free length that the CD 2 that had been mounted on the guide protrusion 52 had a distance with respect to the end face 8. Maintain this distance even during the labeling process.

In the embodiment shown in FIGS. 24 and 25 the following changes have been made compared to the embodiment shown in FIG. 7 . In addition, reference is made to the descriptions of the above-mentioned embodiments.

It is first important that the wall section 52' has a clamping step 62 on its outer surface (see cross-section in FIG. 25). The clamping step 62 matches the free inner diameter of the CD 2. The outer diameter of clamping step 62 is big to the degree that CD 2 can be clamped and fixed. Here it does not or practically does not bring about an inward bending of the wall section 52'.

In this embodiment, a further lead-in step 62' is provided below the clamping step 62, which should first be passed when the CD is inserted. But it has not yet resulted in jamming here.

It can also be seen that dimension a is also chosen to be greater than dimension b in this embodiment. Inserting the pressure cap 43 into the central hole of the label mandrel 54 causes the CD 2 to "float" above the end face 8 of the label mandrel 54. The distance c produced between the end face 8 and the underside of the CD 2 remains even when the label mandrel 54 is pressed down.

The spring 61 is designed as a helical spring, the coil diameter increasing upwards. The coil with the smallest diameter rests on the inner surface of the bottom member 58 . A fixing tube 63 is formed in the center of the bottom part 58 and an opening 64 is formed in the outer surface of the bottom part 58 .

A fixed plug 64 is packed into the fixed pipe 63 upper end, and it is fixed by friction connection in the fixed pipe 63. It can be seen that the fixing plug 64 has a fixing edge 65 which protrudes beyond the outer diameter of the tube 63 and which, against the action of the spring 61 , combines the fixing bottom part 58 with the label mandrel 54 . The outer diameter of the fixing plug 64 is smaller than the inner diameter of the guide protrusion 52 .

FIG. 26 shows an alternative design which differs from that shown in FIGS. 24 and 25 , especially with regard to the spring structure, but is otherwise identical to them.

The important point is the provision of a leaf spring or spring wire 70 which extends transversely to the label mandrel of the sleeve which is configured as a downwardly open sleeve and which is fixed in a cylindrical side wall extending downwardly from the support plate 3 on the radially outer side , the underside of the device is also on this side wall. In more detail, for this purpose a groove 72 is formed on the inner side of the lower end of the cylindrical surrounding side wall 71 , into which groove the end 73 of the spring 70 is inserted. In addition, a locking ring 74 is annularly clamped at the lower end of the side wall 71 . Together with the bottom 75 of the side wall 71 it forms a triangular groove 72 for the end of the spring 70 .

In addition, the annular flange 11 protruding downwards from the support plate 3 and substantially matching the outer diameter of the label mandrel 54 is configured to have a length downwards such that the spring 70 is positioned at the position of the label mandrel 54. In the raised position it presses against the lower end face 76 of the flange.

In addition, the inner sleeve part 77 of the label mandrel 54 which is integrally formed with the label mandrel 54 is configured with the support disk 3, on which the spring 70 extends and is also centrally guided on the inner side of the above-mentioned sleeve part 77 in the assembled state. The guide projection 52 that is fixed with CD 2. At the same time, a safety device is thus formed which prevents the label mandrel 54 from coming off upwards.

In particular, the support disc 3 is connected below the support bottom 79 of the sleeve 77 by two circular segment-shaped tabs 78 , leaving an aperture between the tabs for the spring 70 to extend through it. The end face of the guide projection 52 is supported against the upper side of the support bottom 79 in the assembled state of the device shown in the figure, and then, by means of this support, the CD 2 is pressed down on the label 4 by further pressing on the pressure cover 13, Just right to label CD 2.

For all the pressure caps described here which fasten a CD on their underside, they are also preferably completely separated from the other device part, namely the support disc with the labeling mandrel. That is to say that these parts can be completely separated from each other.

FIG. 23 shows a title sheet 62 having a CD sleeve insertion portion 63. As shown in FIG. The insert part 63 is composed of two rectangular base parts 63' and 63", which have different width dimensions (the length extending in the direction of the transverse edge of the title sheet 62).

The insertion portion 63 is detachably arranged in the title sheet 62 .

To facilitate separation, perforated lines 64, 64', etc. are provided. These perforation lines are configured such that a certain connection still exists. These split lines are structured so that some parts do not cut through the sheet through its full thickness.

The title sheet 62 according to FIG. 23 has the Din A4 format. Alternatively, there is a "letter size" format, ie 21.5cm on the narrow side and 27.2cm on the long side.

Crease lines or separation lines 65 are used for edge chamfers, which conform to the inside thickness of the CD case.

The outermost separation lines 64"" and 64" of the one or other rectangular portion 63', 63" are at different distances from the associated transverse edge 66, 66'.

The outermost dividing line of the larger rectangular portion 63' is at a smaller distance from the associated transverse edge than the outermost dividing line 64"" is relative to the transverse edge 66'.

Furthermore, the rectangular portion 63' or 63" is arranged symmetrically with respect to the longitudinal centerline 67 of the title sheet.

A dividing line 64'' extending between the first and second rectangular portions 63' and 63" perpendicular to the longitudinal length of the header sheet 62 is arranged off-center with respect to the length of the header sheet.

In addition, one side of the dividing line 64'' extends to the left longitudinal side in FIG. 23 . Otherwise it does not extend to the right vertical edge.

All disclosed features are essential to the invention. The disclosure content of this application also includes the entire disclosure content of the associated/accompanying earlier documents (prior application texts), the features of which are also expediently incorporated in the claims of the present application.
