Description

The invention relates to a magazine container for storing tools such as drills, milling cutters or the like, with a receiving body in which around a main axis distributed around a plurality of radially oriented with respect to the main axis, an insertion of tools enabling tool holders are formed, which with respect to the main axis radially having outside facing and in the circumferential direction of the main axis mutually offset outer openings, and having a rotatably mounted on the receiving body around the main axis cover having a covering the outer openings covering wall, which is penetrated by an access opening, by turning the cover selectively opposite one each the outer openings is positionable to allow removal or insertion of a tool.

One from the EP 0 349 951 known magazine container of this type includes a cylindrical receiving body with axially and radially extending tool holders, in each of which a tool for storage purposes can be inserted. The radially aligned tool holders are open to the radially oriented lateral surface of the receiving body, with their mouths are covered by an annular cover wall of a rotatably attached to the front side of the receiving body cover. In this way are the inserted tools prevented from falling out. In order to enable a selective removal of tools, the cover wall is penetrated by an access opening which is positioned by turning the cover in alignment with respect to the insertion openings of the tool holders to remove the desired tool. The tool holders consist of tubes of constant diameter, which extend to just before the cover wall of the cover.

The known magazine container is particularly suitable for accommodating tools with consistently slim shape as is the case for example with drill bits and bits. An accommodation of milling cutters or similar tools, which adjoins a thin mounting shank a relatively wide, provided with cutting work section, is only possible if the pick-up tubes have a total tuned to the dimensions of the working section diameter. This would have, since the largest tool to be taken into account must be taken into account, relatively large diameter of the tool holders result and, accordingly, a greatly reduced recording capacity.

It is therefore the object of the present invention to provide a magazine container which is suitable for receiving tools with respect to a mounting shank voluminöser working section and yet has a high absorption capacity.

To solve this problem, it is provided that the tool holders are formed in a centrally arranged core portion of the receiving body, wherein its outer openings open towards the periphery of the core portion radially outwardly of the core portion is preceded by a larger in size antechamber, the bottom of a radially over the Core portion projecting and spaced to the outer openings bottom wall of the receiving body is limited, and that the cover extends radially beyond the core portion and thereby covers all the antechambers, except in the region of the access opening, above the bottom wall and in the core portion radially outwardly opposite region.

Such a designed magazine container offers the possibility einzustekken tools with their serving for clamping in a machine clamping shaft in the tool holders, so that their possibly a larger diameter than the clamping shaft having, usually provided with cutting work sections in the core section radially upstream vestibule come to lie, which is due to its relative to the tool holders larger cross section in a position to accommodate even relatively bulky work sections. Since the vestibules are located radially further outside than the tool holders, there is already a geometrically greater space for accommodating the working sections of tools, which is optimally utilized here, especially since the tools housed in the tool holders have a fan-like structured arrangement spreading out towards the outside. By the dimensions of the tool holders need only be matched to the usually relatively thin cross sections of the Einspannschäfte of tools, a relatively high number and density of tool holders can be realized within the core portion around the main axis without being affected by possibly larger diameter having working sections of the tools to be, which are housed in the radially outer vestibules. It is also easily possible to store tools whose sections lying in the anterooms strong have different diameter. The cover can be rotated about the suitably passing through the center of the core portion main axis to place the access opening in the area of that vestibule in which a tool to be removed is arranged or in which a previously removed tool to be used again. The remote from the access opening vestibules are shielded by the bottom wall of the receiving body and by the cover of the cover access safe.

Particularly useful is an arrangement in which the individual vestibules are not separated from each other. Instead, the antechambers here are formed by directly adjoining longitudinal sections of a container interior, which is disposed radially outwardly of the core section, which extends in a circular arc around the core section uninterruptedly and to which the individual outer openings open. On the one hand, this increases the space available in the individual anterooms and, on the other hand, facilitates access to the antechambers selected by appropriate positioning of the access opening for removal of a tool. In addition, the production of such a design is more cost-effective than the provision of measures required to create mutually separated vestibules. Nevertheless, a mutual division of adjacent vestibules by separating bodies arranged on the receiving body or comparable separating means is quite possible in order to obtain a kind of compartment division. It is also an arrangement conceivable in which groups of vestibules are realized as constituents of arcuate container interior, in which case these several container interior spaces are separated from each other.

The arcuate container interior can in principle extend over 360 °. But he can also, especially in one Area in which the access opening is positioned when not in use, be interrupted and there, for example, have a subdivision body, which separates the facing end portions of an extension of less than 360 ° having container interior from each other and possibly also closes.

In the dependent claims further advantageous embodiments of the magazine container are listed.

It makes sense if the cover is rotatable in a neutral position in which the access opening is assigned to any vestibule. In this neutral position then all the vestibules are covered by the cover and the tools housed therein shielded to the environment.

In an advantageous development of the receiving body contains in addition to the tool holders a storage compartment for storage of small parts such. Screws or dowels. This storage compartment is closed by a removable or swing-away closure body in a manner that allows opening as required. In this case, the arrangement is selected in particular such that the closure body is covered by the cover hood when the access opening is located in the region of an anteroom and is not accessible. However, for use of the storage compartment, the cover can be twisted into a storage compartment position in which the access opening occupies a position in the closure body, so that its handling for opening and closing the storage compartment is possible.

The storage compartment is expediently formed by a storage container, which is arranged radially next to the core section and located below the cover hood, which simultaneously can serve as a subdivision body for the arcuate container interior, if this has an angular extent of less than 360 °.

Appropriately, a pertinent arrangement that the storage compartment position simultaneously corresponds to the above-mentioned neutral position.

Optimum access to the tools is possible if the access opening is located partly in the top wall section opposite the bottom wall of the receiving body and partly in the radially outer wall section of the cover wall of the covering hood, wherein there is no subdivision. It is then possible to access the respectively selected vestibule from both radially outside and from above and in the area between them.

In conjunction with a storage compartment, the aforementioned design offers the advantageous possibility of disposing the detachable or pivotable closure body on the upper side of the storage compartment opposite the bottom wall of the storage compartment in an optimally accessible manner, without problems due to the section of the access opening formed in the upper wall section of the cover wall of the cover hood is accessible when the cover has been turned into the storage compartment position.

The core section is in particular of columnar design, wherein it projects upwards from the bottom wall lying below. The outer openings of the tool holders are in this case expediently on the radially outwardly oriented lateral surface of the core portion. The cover itself is preferably on the upwardly projecting upper end face of the core portion so as to cover not only the bottom wall but also the core portion.

The tool receptacles, which are preferably designed as plug-in receptacles, can be defined by a plurality of holding brackets arranged alternately on the upper side and on the underside, which are expediently offset relative to one another in the longitudinal direction of the tool receptacles, which simplifies removal from the mold in the production of pointed casting.

Preferably, the tool holders are formed and adapted to the male portions of the tools that the respectively inserted tool is held slightly clamped without the involvement of the cover, so that a certain axial fixation takes place, the uncontrolled movements of the tools along the tool holders prevented and yet at Demand a withdrawal of the tools allowed without much effort.

Particularly advantageous, however, is a design in which the tools seated in the tool holders are alternatively or additionally releasably clamped between the core portion of the receiving body and the cover. The core portion and the cover take over here even directly the function of clamping elements, so that can be dispensed with additional, separate clamping elements.

In this context, it is advantageous if on the underside of the cover a concentric with respect to the main axis, annular projection is formed, whose radial distance from the main axis is chosen so that it comes to lie in the region of the tool holders and the clamping surfaces on its underside comprising, against the uncovered by the tool holders sections of the inserted tools can press to clamp the tools with opposite, ie upwardly oriented support surfaces of the core portion.

Particularly advantageous is a pertinent realization of the clamping measures that takes place by appropriate coordination with respect to the dimensions of the tools clamping all those tools that are currently not in the access opening. The tool, however, in whose area the access opening is positioned, is not or only slightly clamped and can thus be easily pulled out.

An axially immovable clamping of the recorded tools is particularly advantageous, because thereby even when vibrations of the magazine container a migration of the recorded tools radially outward and in contact with the cover wall is prevented. The latter could lead due to sharp cutting on the tools that the cover is damaged and / or the cover jammed with respect to the tools.

To realize the selective release of each selected by positioning the access opening tool, it is advantageous if the tool holders have below each other at the same level lower support surfaces, which arranged below the cover, facing each other also at the same level and facing downward clamping surfaces is. The tools are thus each clamped between an opposing pair of surfaces consisting of a lower support surface and a clamping surface. In the area of access opening, however, such a clamping surface is missing, for example by forming a sufficiently large recess, or is a substitute a holding surface is present whose distance from the lower support surfaces is greater than that of the clamping surfaces, so that the tools sitting in the selected tool holder tools can be pulled out with little or no effort.

If the clamping surfaces are recessed and in particular concave, results from the interaction with the inserted tools when turning the cover a locking function. This is associated with the advantage that the access opening can always be positioned in a precisely aligned manner in the respectively selected vestibule.

Conveniently, the cover is biased with respect to the core portion in its central region in the axial direction of the main axis. The bias takes place in particular in the central region, preferably under elastic deformation of the cover and expediently using a prestressing acting bayonet closure device. In this way, a uniform transfer of the clamping forces on the tools is possible.

The pretensioned in the central region cover expediently slidably with the downwardly projecting outer edge of its cover wall on the bottom wall of the cover body. By biasing a certain stiffness is achieved here, which counteracts an uncontrolled rotation of the cover.

Conveniently, the downwardly projecting edge of the cover also contributes to the rotary mounting of the cover with respect to the receiving body by this edge dips into a centering and rotational bearing effective depression of the bottom wall, which is preferably formed as extending in the circumferential direction of the bottom wall guide groove.

The figures show a combination consisting of a magazine container designated overall by reference numeral 1 and a plurality of tools 2 stored in the magazine container 1 for selective removal.

The tools 2 are, in particular, machining tools for machining or abrasive machining of workpieces. Each tool 2 contains a clamping shaft 3 serving for releasable clamping in a processing machine and an axially adjoining working section 4 provided with tool-typical cutting edges, which is brought into engagement with the workpiece to be machined during the intended use of the tool 2.

The tools 2 are, for example, drills and / or milling cutters. Special milling cutters have the frequent feature that their working section 4, in particular, is made out Fig. 3 and 5 can see well, a larger and usually much larger outer diameter than the clamping shaft. 3 The magazine container 1 comprises a preferably circular contoured, provided on the outer circumference if necessary with a suspension tab 6 receiving body 5, which consists in particular of plastic material. At the top of the receiving body 5, with its open side ahead, a cover 12 is attached, which is rotatable relative to the receiving body 5, to the longitudinal axis of the receiving body 5 hereinafter referred to as the main axis 13, extending through the centers of the receiving body 5 and the cover 12 extends therethrough.

The receiving body 5 contains in its central region a columnar in the axial direction of the main axis 7 extending core portion 8. It is suitably designed substantially circular cylindrical and has a radially outwardly oriented lateral surface 14. In the region of the cover 12 facing upper end face 15 of Core section 8 appropriately graded in the region of its outer circumference.

The core section 8 rises axially from an expediently substantially disc-shaped bottom wall 16, which extends in a ring-shaped, concentric arrangement, radially outward around the core section 8. At its outer edge, the bottom wall 16 is expediently provided with a ring-shaped self-contained groove-like recess 17, the slot-shaped opening of which faces the top of the magazine container 1 and whose function will be discussed. The optional suspension tab 6 is in particular radially radially outwardly integrally formed on the outer edge portion of the bottom wall 16.

On the bottom wall 16, immediately radially following the core portion 8, sits only a relatively small circumferential length portion the bottom wall 16 engaging storage container 18 whose floor plan corresponds to that of a radially inside verkappten circular sector. According to Fig. 4 It is advantageous if the bottom wall 16 at the same time forms the container bottom wall, although it is also possible to place the storage container 18 as a separate component on the bottom wall 16.

The storage container 18 projects radially next to the core portion 8 upwards, wherein it can project beyond the core portion 8 a piece. In the radial direction, it extends to the outer edge region of the bottom wall 16, wherein it ends in front of the groove-like depression 17.

The storage container 18 encloses with its wall a storage compartment 22, which is particularly suitable for the storage of bulk material present small parts such as screws or dowels.

The storage compartment 22 has an opening 23 facing away from the bottom wall 16. A closure body 24, which is designed in particular in the manner of a cover, extends over it and is either removable or, as in the exemplary embodiment, pivotally mounted. The closure body 24 may optionally in a Fig. 1 to 9 resulting, the storage compartment 22 occlusive closed position or in a Fig. 10 apparent, the opening 23 releasing open position shifted and in particular be pivoted. As an example, he is in the embodiment for making accessible the storage compartment 22 is pivoted upward, with its pivot bearing portion 25 of the core portion 8 facing inside of the storage container 18 is assigned. Conveniently, the closure body 24 with the storage compartment 22 bounding Wall of the storage container 18 by latching means 26 releasably latched.

In the core portion 8 of the receiving body 5, distributed around the main axis 13 around, a plurality of the main axis 13 radially oriented tool holders 27 are formed. With respect to the main axis 13 radially extending longitudinal axes of the tool holders 27 are indicated by dash-dotted lines 28. Conveniently, the tool holders 27 are evenly distributed and are also expediently at the same axial height with respect to the axial direction of the main axis 13.

The tool holders 27 are formed in the form of holes and terminate with radially outwardly oriented outer openings 32 to the lateral surface 14 of the core portion 8. These outer openings 32 are consequently arranged in the circumferential direction of the main axis 13, ie around the main axis 13, at a distance from each other. Only in the area of the sector in which the storage container 18 is located, no tool holders 27 and outer openings 32 are present.

Each outer opening 32 is axially outwardly preceded by a separate vestibule 38, whose cross-section is greater than that of the associated tool holder 27. The vestibules 38 close radially to the outside of the core portion 8 and are thus radially inwardly of this core portion 8 and at the bottom of the bounded at a distance below the outer openings 32 bottom wall 16.

The preferably substantially cup-shaped or bowl-shaped cover 12 includes a centrally disposed mounting wall 33 preferably circular outline to which outside, under concentric arrangement, a designated as a cover wall 34 further wall section connects. The mounting wall 33 is located opposite the upper end surface 15 of the core portion 18 and is connected via the closure part 35 of a bayonet catch 36 (see Fig. 7 ) held in a rotatable manner on the core portion 8. The cover wall 34 extends radially beyond the core portion 8, wherein it has an adjoining the mounting wall 33, the bottom wall 16 at a distance axially opposite upper wall portion 34a and an adjoining, down to the bottom wall 13 extending outer wall portion 34b , which is opposite to the lateral surface 14 of the core portion 18 with a radial distance. The mounting wall 33 may be set slightly lower with respect to the upper wall portion 34a with the interposition of an annular step 37.

The cover wall 34 delimits together with the inner core portion 8 and the bottom wall 16, the antechambers 38. The latter adjoin each other peripherally around the core portion 8 around directly to each other, preferably without mutual separation or separation directly into each other. In other words, the antechambers 38 are formed by directly adjoining longitudinal sections of a container interior 42 which extends in a circular arc around the core section 8, being radially inward of the core section 8, on the underside of the bottom wall 33 and otherwise of the cover cover 12 is limited. In other words, the container interior 42 is not completely closed due to the inserted storage container 18 annular space.

In an embodiment not shown, the adjacent vestibules 38 are arranged on the receiving body 5 Partitions partitioned each other, so that there is a compartment division. However, since the tools 2 are held securely in the tool holders 27, such subdivision means, even in favor of a simpler manufacturing, can be dispensed with.

The cover wall 37 of the cover 12 is penetrated locally by an access opening 43. Their measured in the direction indicated by a double arrow direction of rotation 44 of the cover 12 approximately correspond to those of an anteroom 38. Thus, there is the possibility of the access opening 43 by turning the cover 12 selectively in the area opposite each of an antechamber 38 and thus associated with this vestibule 38 Position outer opening 32 to allow access to the thus selected vestibule 38.

The 8 and 9 show a state in which the access opening 43 is positioned in the region of a vestibule 38, so that there is the possibility to insert a tool 2 according to double arrow 45 through the access opening 43 with its clamping shaft 3 in the associated tool holder 27 or pull out of this.

While not in use, the cover 12 can be in the example from Fig. 1 . 6 and 10 rotate apparent neutral position in which the access opening 43 angularly with respect to the main axis 13 occupies the same position as the storage container 18. Thus, the access opening 43 is assigned to any of the vestibules 38 and all vestibules 38 are shielded from the environment.

If there were no storage container 18, the access opening 42 positioned in the local area would be without function. Instead of the storage container 18, if necessary, a wall arranged on the receiving body 5 could be provided which closes the access opening 43 in its neutral position from the inside.

Due to their positioning in the area of the storage container 18 and its storage compartment 22, the neutral position in the embodiment can also be referred to as a storage compartment position. Here, the access opening 43 in the neutral position has the function of allowing access to the storage compartment 22. More specifically, the access opening 43 inter alia comes over the closure body 24 and allows access to the closure body 24 so that it can be handled for the purpose of opening or closing the storage compartment 22.

Preferably, the access opening 43 extends without interruption both at least partially over the outer wall portion 34b and at least partially over the upper wall portion 34a. As a result, a tool 2 to be removed or inserted can be comfortably detected both axially from the outside and from above if the access opening 43 is positioned accordingly. The removal and insertion of a tool 2 takes place through the outer opening section 43b of the access opening 43 formed in the outer wall section 34b. The formed in the upper wall portion 34a upper opening portion 43a of the access opening 43 allows in the embodiment in particular the pivoting up of the cover body formed as a cover 24 for opening the storage compartment 22, as it is made Fig. 10 is apparent.

If there is no storage container 18 or is the closure body 24 pointing radially outwards Side of the storage container 18, the access opening 43 may also be formed exclusively in the outer wall portion 34 b.

As an anti-theft device during the sales phase of the magazine container 1 can be formed on the receiving body 5 an easily breakable or cutable locking tab 45 which protrudes into the central opening of the cover 12 in the access opening 43 and acts as a stop element that prevents rotation of the cover 12 in both directions , Before the first use of the magazine container 1, the locking tab 45 is removed by breaking or cutting, which is why it is indicated in the drawing only by dash-dotted lines. Preferably, the securing tab 45 is formed on the storage container 18, in particular by integrally molding on the wall of the storage compartment 22. The measured in the direction of rotation 44 width of the securing tab 45 suitably corresponds approximately to the corresponding measured width of the access opening 43 at the relevant point.

An advantage of the exemplary magazine container 1 is that the cover 12 and the core portion 8 cooperate as clamping elements, between which the seated in the tool holders 27 tools 2 are releasably clamped so that they even with a concussion of the magazine container 1 in conjunction with an inclined position the same do not tend to slip out of the tool holders 27 and come with the cover 34 in potentially damaging contact.

In order to realize this clamping function, the tool holders 27 are at least partially open at their upper side facing the cover 12, so that at least one Part of the inserted clamping shaft 3 is axially accessible from above. In order to generate the open areas, the tool holders 27 may be designed in a particularly advantageous manner.

The core portion 8 is formed in this context as a hollow body, in particular cup-like structured with downwardly facing opening. In Fig. 7 If you look from below into the interior 46 of the hollow core section 8 into it.

As already mentioned, the core section 8 is stepped at the outer edge of its upper end region. He therefore has a the lateral surface 14 defining lower longitudinal portion 47 of larger diameter, followed by an upper length portion 48 of smaller diameter, connected via a perpendicular to the main axis 13 extending annular intermediate wall 52. The tool holders 27 include a running in the intermediate wall 52 and the lower longitudinal portion 47 passing through channel-shaped longitudinal portion 53 which is open to the outer surface 32 to the lateral surface 14 toward the formation of the outer opening. Axially inside it penetrates the wall of the upper longitudinal section 48, so that the tool holder 27 is open into the interior 46 of the core section 8. An inserted tool 2 lies with its clamping shaft 3 in the channel-shaped longitudinal portion 53 and also immersed in the interior 46 a. In Fig. 7 the protruding into the interior 46 end portions of the Einspannschäfte 3 are clearly visible.

Each channel-shaped longitudinal section 53 forms an upper support surface 54 pointing upwards to the cover 12, on which the clamping shaft 3 of the inserted tool 2 is supported. In the embodiment, the lower support surface 54 is composed of a plurality of surface sections together, one of which is formed by the indented upper edge of the lower longitudinal portion 47 of the core portion 8 and the other at an axially spaced in this regard, arcuately shaped lower headband 55th

Between the two surface sections of the lower support surface 54 defined in this way, there is a lower recess 56, which is opposite a top retaining bracket 57 which bridges over the channel-shaped longitudinal section 53 and which is likewise curved. An inserted clamping shaft 3 is thus spanned by a lower headband 55 and an axially spaced upper headband 57 and fixed in the transverse direction.

The recess 56 allows in the injection molding of the receiving body 5 a favorable penetration for a the upper headband 57 predetermining mold and thus facilitates the demolding process. The entire receiving body 5 can thus be very easily removed axially, ie in the axial direction of the main axis 13.

Due to the thus designed tool holders 27, the inserted tools 2 are held without the cooperation of the cover 12 in the transverse direction and can not tip over despite relatively heavy working section 4 in the rule.

Conveniently, the tool holders 27 defining boundary surfaces are matched to the cross-section of the male shank 3, that the inserted tool 2, even without the cooperation of the cover 12 undergoes a slight clamping and is thereby prefixed frictional. However, the tools 2 can still be moved relatively easily in the tool holder 27 axially.

Above the channel-shaped longitudinal section 53, the tool holders 27 are each partially open. An inner open area 58 is located between the circumferential wall of the upper length portion 48 of the core portion 8 and the spaced upstream upper headband 57. An outer open area 59 is located axially between the upper headband 57 and the lateral surface 14, at the same level as the outer Surface portion of the lower support surface 54th

In order to meet the mentioned clamping function, the cover 12 is provided at the outer edge of its mounting wall 33 with an axially downwardly projecting annular projection 62 which is arranged coaxially to the main axis 13 and whose radial distance from the main axis 13 is the same size as the Accordingly, measured radial distance between the main axis 13 and the outer open areas 59. Thus, the annular projection 62 extends beyond the outer open areas 59 of all tool holders 27 away.

The annular projection 62 forms with its downwardly facing edge surface of a plurality of clamping surfaces 63, which are recessed and in particular concave and which are distributed in a grid around the main axis 13, which corresponds to the distribution grid of the tool holders 27. If the cover 12 is rotated in the neutral position, each tool holder 27 is located in the region of the outer open area 59 above one of the clamping surfaces 63 against.

The mutual distance between the lower support surface 54 and the clamping surface 63 extending beyond it is slightly smaller than the diameter of the clamping shaft 3 when the tool 2 is not inserted. Therefore, the inserted tool becomes in the region of its clamping shaft 3 between the lower support surface 54 and the clamping surface 63 clamped axially immovable. Even with strong shocks is thus prevented that the tools 2 slip out of their tool holders 27.

The required for the clamping action bias is achieved by the above-mentioned bayonet fitting 36. The closure part 35 passes through from above a first passage opening 64 formed centrally in the attachment wall 33 and subsequently a second passage opening 65 coaxial therewith, which is formed in the upper end wall 66 of the core section 8 defining the upper end face 15. With a head portion 70 it is supported from above against the mounting wall 33 from. On the underside of the upper end wall 66, a bayonet-like latching structure 67 is formed, with which a locking member 68 projecting from the closure part 35 engages when the closure part 35 is rotated during its assembly. As a result, the cover 12 is biased in the region of its mounting wall 33 down toward the upper end face 15, but without it coming to rest. It remains on 4 and 5 apparent gap 69 between the mounting wall 33 and the upper end surface 15th

The counterforce applied by the cover 12 results from the fact that the cover 12 is supported by the downwardly projecting outer edge 73 of its cover wall 34 on the bottom wall 16. Due to the flexibility of the existing in particular of a thin plastic material cover 12 experiences the cover 12 by the bias a certain elastic deformation. The edge 73 expediently engages in the groove-like recess 17 and is supported therein. At the same time, the groove-like depression 73 acts as a guide groove for centering and pivoting the cover 12. Alternatively or additionally, the cover 12 may, however, also be rotatably mounted on the shaft of the closure part 35 passing through the first passage opening 64.

Instead of the bayonet lock device 36, the axial bias between the cover 12 and the receiving body 5 could also be caused by other biasing means.

Due to the existing to some extent flexibility of the cover 12, in particular due to the existing gap 69, the cover 12 can be rotated in spite of the positive cooperation between the clamping surfaces 63 and the tools 2 under each temporary elastic deformation with relatively little effort according to double arrow 44. As a result, the clamping surfaces 63 each temporarily out of engagement with the tools 2, to then apply the next tool in the series. Due to the expediently existing recessed design, the clamping surfaces 63 act simultaneously as latching means which fix the cover 12 releasably latching in the various rotational positions by the interaction with the tools 2. This provides a further level of security against unwanted twisting of the cover 12 with respect to the receiving body. 5

In one embodiment, not shown, the biasing means formed for example by a bayonet catcher 36 are designed so that they can be temporarily detached to that tool 2, which is located in the access opening 43, without risk of injury with little effort to pull out of the tool holder 27 can , By such a temporary release of the bias voltage, if necessary, the rotation process 44 can be facilitated. In the embodiment, the tool 2 selected by positioning the access opening 43 can be easily removed even without releasing the biasing means. This is due to the fact that the cover 12 is designed such that it exerts less or no clamping force with respect to a tool 2 currently assigned to the access opening 43, compared with the clamping force exerted on the other tools 2. The respectively selected tool 2 is thus automatically released for removal, without the need for actuation of the biasing means.

To realize this, the lower support surfaces 54 of all tool holders 27 are arranged lying in the axial direction of the main axis 13 at the same height in the embodiment. If one assumes that the clamping shanks 3 of all the tools 2 to be stored in one and the same magazine container 1 have the same diameter, this leads to the fact that the upper surface sections associated with the outer open regions 59 also have the same diameter Clamping shanks 3 are at the same height. The corresponding contour line is in Fig. 8 indicated at 74.

All clamping surfaces 63 of the cover 12 are mutually also at the same height relative to the axial direction of the main axis 13. The corresponding contour line is in Fig. 8 at 75 dashed and is referred to below as the lower contour line 75. When the clamping surfaces 63 act on the tools 2, the lower contour line 75 coincides with the contour line 74 defined by the tools 2.

In the area of the access opening 43, the annular projection 62 is provided with a downwardly open recess 76, which in the axial direction of the main axis 13 has a greater depth than the clamping surfaces 63. Its overhead vertex lies on an upper contour line 77, which is spaced to the lower contour line 75 by a certain amount.

If the access opening 43 for removing a tool 2 is positioned in the region of an antechamber 38 - in particular under position specification of the latching interaction between the concave clamping surfaces 63 and the clamping shafts 3 - the recess 76 comes over the outer open area 59 of the tool 2 located within the access opening 43 to lie. The degree of spacing between the lower contour line 75 and the upper contour line 77 is chosen so large that the cover 12 here no clamping function with respect to the selected tool 2 exerts - it is preferably no contact - and this can therefore be easily pulled out.

Alternatively, the height distance between the contour lines 75, 77 could also be set such that the upper edge surface of the recess 76 acts as a holding surface, which abuts on the tool 2, but with significantly lower bias than is the case with the clamping surfaces 63, so that the clamping action is greatly reduced and in turn the tool 2 can be pulled out with little effort or even plugged in again.

The clamping surfaces 63 are not necessarily designed as edge surfaces of depressions. They could also be formed directly by a rectilinearly contoured edge region of an annular projection 62, if no special value is placed on a latching function.

The non-clamping of the currently selected tool 2 could be caused instead of a recess 76 by a simple interruption of the annular projection 62.

In the stepped transition region between the mounting wall 33 and the cover wall 34, a recess pattern 78 may be formed in the outer surface of the cover 12, which facilitates the gripping of the cover 12 for introducing the torque.

In the area of the bottom wall 16 within the container interior 42 retaining tabs 79 can be formed on the receiving body 5, which serve to fix an inserted production formation carrier.

By the cover 12 as the receiving body 5 is contoured circular, several magazine container 1 can be conveniently stacked. A recess 83 on the underside of the bottom wall 16 allows a centering placing on the cover 12 of an underlying magazine container. 1

By the cover 12 is formed transparent, the stored tools 2 and any product information from the outside are always clearly visible.

About the centrally acting biasing means, here in the form of a bayonet fitting 36, a uniform contact pressure is built up.

By the width of the access opening 43 is not greater than the width of each vestibule 38, the risk of injury when removing a required tool 2 is minimized.

If the cover 12 is rotated in the neutral position, all tools 2 are automatically clamped securely. It is then assigned to each tool holder 27, a clamping surface 63.

Due to the fact that the tools 2 are stored with radially inwardly pointing clamping shaft 3, which have larger transverse dimensions working sections 4 are radially further out, where due to the larger dimensions of the receiving body 5 in the coinciding with the direction of rotation 44 circumferential direction more space is available ,
