Description

Magazine and method for transferring a module to a magazine

The invention relates to a magazine with at least one place for receiving a module, which can be interchangeably arranged on a machine or a device. The invention further relates to a method for transferring such a module to a magazine

In particular, the invention relates to the fields of machine tools and coordinate measuring devices. In these fields, tools (eg, machining tools or scanning tools, such as styli) or sensors for performing certain tasks (eg, measuring the geometry of difficult-to-access surface areas of workpieces, eg, bores) are replaced It should be noted that these are in many cases high-precision machines or devices, so that when transferring a module (eg the tool or measuring sensor) to the magazine or vice versa, the procedure must be gentle. The devices and machines are In many cases, for example, in gantry-type coordinate measuring machines, the part (eg the measuring arm of a coordinate measuring machine) can be attached to a any point within In this operating range, the magazine can also be located from which at least one module can be accommodated. If a measuring sensor of a coordinate measuring machine is mentioned here, then this term includes any type of sensors and scanning tools, in particular pushbuttons ( z B styli without their own sensor for coupling to a sensor) for the mechanical probing of Werkstuckoberflachen, optical buttons and other measuring devices that can be interchangeably arranged on the device or the machine The sensor may also be a device to turn in turn Therefore, the sensor z B can also have a device in which signals recorded when carrying out coordinate measurements are processed. The sensor can also have a control device with which at least the operation of a part of a coordinate Enmessgerats or a machine tool is controlled, for example, the operation of a mechanical or optical probe

The magazine has a plurality of storage locations, each for receiving pin modules for use in measuring workpiece dimensions on coordinate measuring machines on There are permanent magnets on Provided With Each Memory Space To accommodate a pen module located in the magazine by a holding module of a coordinate measuring machine, the holding module is moved down until it engages the pen module. Further down movement decouples the pen module from the storage space, so that it It will be possible to remove the pen module from the storage location. The aforementioned magnets hold the pen module in the magazine slot until the downward force generated by the receiving CMM is so great that the pen module of FIG the storage space lost and also removed from the magnet

The disadvantage of this is that on the one hand a relatively large force is needed to keep the module safely in the magazine space and on the other hand, the correspondingly greater force to remove the module from the magazine location, must be applied by the coordinate measuring In addition, the coordinate measuring the module moving in a certain direction to remove it from the magazine place Conversely, the coordinate measuring device for transferring the module to the magazine must first position the module exactly in the correct position of the magazine location and then releases the Halteverbmdung to the module by a correspondingly high force Frequently, this holding force is a magnetic force of one or more permanent magnets During such a tear-off process, care must be taken that the module is exactly at the desired position in the magazine space verb In particular, when magnetic forces from permanent magnets are used to hold the module in the magazine, jerky movements of the coordinate measuring machine may occur Re-adjustment of the measuring systems may require or even damage the device

It is an object of the present invention to provide a magazine and a method of the aforementioned kind, which reduce potentially harmful effects in the transfer of a module to a magazine on the transferring machine or the transferring machine. In particular, it should be possible, a module even then to hand over to the magazine when the transferring machine or transferring device is unable to generate high transfer forces or transfer speeds, including high inertia forces due to a large mass in the case of low speed

In accordance with one aspect of the present invention, the actual detachment operation in which the module is replaced by the device or machine (hereafter the Therefore, the device is relieved of the task of performing a certain movement or exerting a minimum force to separate the retention connection to the module. Also, the device does not need to be complex Have facilities that reduce the force applied by the device holding force, as is the case, for example, in the case of electromagnetic holding devices

In particular, a magazine is proposed with at least one space for accommodating a module, in particular a replaceable tool of a machine tool or a replaceable measuring sensor of a coordinate measuring machine, wherein the space comprises a holding device for holding a module and a Abloseeinnchtung for detaching the module from a machine or a Gerat the module holds, wherein the space is configured so that the Abloseeinnchtung a module from a machine or from a device that holds the module, and removes, so that the module of de ^r machine or the Device to the holding device handed over wirα

The invention also proposes a method for transferring a module, in particular a replaceable tool of a machine tool or a replaceable measuring sensor of a coordinate measuring machine, from a machine or a device to a magazine with at least one space for receiving the module, the module being characterized by a detachment of the magazine from a machine or device that holds the module, is loosened and removed so that the module is transferred from the machine or device to the magazine

For the Ablosevorgang, ie for the removal and removal of the module from the device energy is needed The energy can be supplied to the magazine during the execution of the Ablosevorganges, eg in the form of electrical energy with which a motor of the magazine is operated is preferred in that the energy required for the detachment process is stored in the magazine or in a device mechanically connected to the magazine. For example, an electromagnetic energy store may be used. Alternatively or additionally, energy may be stored by pneumatic or hydraulic means, wherein a gas or a liquid is under pressure and the pressure is used to perform the Ablosevorgang Pneumatic or hydraulic devices can also be used when the energy is not or not completely stored in the magazine, but is supplied from the outside However, an embodiment in which the energy is stored in mechanical form in the magazine is particularly preferred. For this purpose, the Abloseeinπchtung preferably has a tensionable elastic means, for example, one or more springs (eg helix-shaped springs)

Stored mechanical energy has the advantage that it can be easily stored without loss In addition, the mechanical energy can be stored without great effort and at low speed of movement, especially when removing a module from the magazine, as will be described later

It is therefore preferred that the Abloseeinnchtung comprises a tensionable elastic means, wherein the space is designed so that the elastic means in a tensioned state, when the holding means does not hold a module, or can be brought into the tensioned state and that in the elastic Device stored mechanical energy when the elastic device is in the tensioned Zusianα, is useful to a module from a machine or from a device that holds the module to solve and remove so the module from the machine or the device the holding device is handed over

In particular, the space may be configured such that the elastic device is in a relaxed state when the holding device holds a module. The energy stored in the magazine can therefore be used to disengage and remove the module from the machine or device

Therefore, when the stored energy is mechanical energy, the tensioning elastic device is in a tensioned state when there is no module at the magazine location. During and / or after the transfer of a module from the machine or device to the magazine location the elastic device is in the relaxed state, whereby the stored energy is released and is used to solve the module of the machine or the device and remove Especially when the module is held on the machine or the device by means of magnetic forces The distance traveled by the module during removal does not have to be large. For example, the distance is only one or two tenths of a millimeter. The magnetic force between the device and the module decreases so much that the device is moved away from the module without significant effort can Preferably, a soft stop is provided at the magazine location, to which the module and / or the holding device that holds the module stops when the module is removed from the device. A soft stop can be achieved, for example, by striking surfaces of involved ones But a soft stop can also be achieved in that at least one of the abutting parts has an area that is elastically deformable in all these cases prevents the module is displaced by a shock in its holding position with respect to the holding device or even damaged by the impact

In a preferred embodiment, the holding device is already in contact with the module to be transferred when the module is removed from the machine or device. In particular, the Abloseeinπchtung the holding device and thus also move the module held by the holding device, so that the module of the For example, the machine or apparatus will position the module in the fixture or on the fixture so that the fixture is held by the fixture and at the same time by the machine or apparatus. The fixture then moves the fixture together Preferably, the module is moved in a first direction by the stripper mechanism to release and remove the module from the machine or apparatus. The holder is configured such that the module before moving in the he In other words, in the case of the release of energy stored in the magazine, the module is moved in the first direction to move the module away from the machine or the device to be loosened or removed, wherein the module is introduced into the holding device before the release of the stored energy in the second direction, which is transverse to the first direction When the module is first introduced into the holding device or holding device and module together engage and the module is only then removed from the device, the holding device can be constructed in a simple manner without complex and possibly malfunctioning components, such as B without moving brackets, which must be brought into a holding position to hold the module Rather, the device itself einfuh the module in the holding device or engage with it. The device is therefore robust and reliable. The device itself does not have to perform complex movements and is therefore relieved of tasks which it would have in the state of the art It is only necessary to apply the counterforce required to replace the module. For example, the device can be fixed in position as soon as the module has been inserted into the holding device

According to one embodiment of the invention, the magazine has a triggering device which releases energy stored in the magazine upon actuation of the triggering device in order to release and remove the module from the machine or device. In particular, the energy can therefore be provided to the relay device the energy stored in the magazine is sufficient to operate the termination device so that the termination device removes and removes the module from the device. The stored energy is preferably stored mechanical energy, eg mechanical energy stored in said elastic device Energy ZB, the elastic device on a spring accumulator

In principle, all conceivable embodiments for the Ausioseemricntung in question In the case of a mechanical energy storage, the release device z B can be electrically operated example, an electrically actuatable magnetic switch loose a mechanical locking element, so that the mechanical energy is released is preferred However, that the device, on which the module is still attached, the triggering device actuated ZB can after the correct positioning of the module in the holding device or upon reaching the correct holding position of the module in the holding device or on the holding device, the triggering device are mechanically or otherwise actuated by mechanical actuation abuts the device and / or the module z B to a mechanically movable actuating element of the release device, whereby z B via a lever mechanism, the release device is unlocked and the mechanical energy is released In another For example, upon reaching the correct position of the module in or on the holding device, an electrical contact is closed or an electrical switch is actuated, which causes the triggering device to release the stored energy. Other possibilities of actuating the triggering device by the device and / or For example, the device may execute a predefined movement or exert a predefined force on the magazine after the module has been correctly positioned in or on the holder by the device. This predefined movement and / or force Then, when the triggering device ZB operates in the above-described case where the module is inserted in the second direction in the holding device, the device can make a movement transverse to this second direction (eg in the first direction) and thereby actuate the triggering device It is also suggested that the energy stored in the magazine be provided thereby (ie, transmitted to the magazine) that upon transfer of a module located in the magazine location to a machine or apparatus, that machine or apparatus will apply the energy to the magazine transfers. For example, in the case of a mechanically stored energy, the machine or device performs a motion that stores the energy in the magazine. In this case, a part of the magazine or the magazine location against elastic forces (eg, against spring forces) are moved. In the case of the above-mentioned elastic device, this thereby enters the tensioned state.

In other words, the elastic means is adapted to be brought into the tensioned state by the machine or apparatus to receive a module held by the holding means before the machine or apparatus removes the module from the holding means. This corresponds to a method in which the energy required to store the energy in the magazine is at least partially transferred from a machine or device to the magazine before and / or while the machine or device is held by the magazine Module takes over.

The magazine preferably has a detection device with which it is detected whether a module is located in the magazine location and / or whether the energy required for detaching and removing the module from the device is stored in the magazine With the aid of such detection, the device can an information can be transmitted by means of which the device can check and / or decide whether it transfers a module to a specific magazine location. For example, in the case of a mechanically stored energy, an electrical contact can be closed in the tensioned state of the elastic device. By detecting this closed state, the detection device determines that the mechanical energy is stored. The detection device may e.g. wirelessly or via an electrical line connection to the controller of the device, e.g. be connected to the coordinate measuring machine.

In a particular embodiment of the magazine this has an elastic device which is designed to be brought to a machine or a device in a tensioned state upon the transfer of a held by the holding device module and after removing the module from the holding device by transition in a relaxed state to bring the holding device in a predefined state (eg in a predefined position) in which the holding device again receive a module This makes it possible already on the basis of the state (eg position, position is also understood an orientation) of the holding device to decide whether the magazine location is ready for receiving a module Here, the predefined position not only of the elastic device In particular, the elastic device is a second elastic device, wherein the first elastic device may be the device described above in which the mechanical energy for detaching and removing the module from the device is stored

In a corresponding method, the machine or apparatus transmits energy to the magazine prior to and / or during the transfer of the module from the magazine, the energy being used to move the magazine to a predefined state during and / or after the module is accepted in which the magazine is again ready to accept a Modu. The predefined state may, for example, be the predefined position

Measuring sensor is held in the magazine place

The embodiment of the invention described below is a preferred exemplary embodiment. In the description of the exemplary embodiment, features of the invention are described which may also be present in other embodiments

1 shows a section through a magazine location and a free end of a coordinate measuring machine 1. The free end may be, for example, the end of a sensor with Sensonk for generating a scanning signal, the end of a part of such a sensor or the end of an arm In particular, the module may be a scanning tool (eg, a stylus, or a combination of styli), a part of a Sensonk, or a full sensonk sensor

For example, the free end is formed by a freely movable in several directions arm of the coordinate measuring machine 1 A module 3, z B a measuring sensor with a plate-shaped coupling piece 4 is at the free end z B by magnetic forces of a in held the module 3 and / or arranged in the coordinate measuring machine 1 permanent magnet

In order to transfer the module 3 to the magazine location, the coordinate measuring machine 1 has already introduced the module 3 into a holding device 5 in front of the snapshot shown in FIG. 1. The holding device 5 has a recess 2 which is open at the side (above the image plane) on the basis of a further exemplary embodiment (US Pat. 10 and 13) is described with reference to a three-dimensional representation nor a similar magazine space, which also has a laterally open recesses

1 shows a dot-dash line L, which approximately perpendicularly intersects the surface of the free end of the coordinate measuring machine 1 and extends approximately centrally through the magazine location. The recess 2 is also on the surface of the holding device 5, which faces the free end of the coordinate measuring machine 1 , open from this opening, the recess 2 extends along the line L and extends in its course in the interior of the holding device 5 Therefore, a wider area 4a of the module 3 can be introduced from the coordinate measuring machine 1 in the enlarged part of the recess 2

More generally, the holding device of the magazine location and the module are matched in their dimensions and in their shape designs to one another such that the holding device can detach and remove the module from the free end of the device when it applies the force required for this purpose

It can not be seen from FIG. 1 and the further figures of this exemplary embodiment that the holding device 5 can have a downwardly opening so that a part of the module or parts connected thereto (eg a stylus for mechanically touching workpiece stucco surfaces) pass through the holding device From the drawing (Figures 10 and 13) of the already mentioned further exemplary embodiment, however, a similar design can be seen, in which the opening passes down

The holding device 5 has laterally, transversely to the line L ₁ projecting portions 6a, 6b, which may also be a circumferential, annular area The projecting portions 6 form a Abstück, at least one spring, in the exemplary embodiment two Plungers 9a, 9b The springs may be, for example, hehxformige springs. However, other spring devices are also suitable, eg with leaf springs. On at least one side, the at least one spring is supported 9 at a in the direction of the line L against the holding device 5 movable element 7 from

More generally, the holding device is movable relative to an element of the magazine, wherein in a relative movement, a spring device is either stretched or relaxed, depending on the direction in which the relative movement takes place

Furthermore, FIG. 1 shows a release device 8, upon actuation of which a relative movement of the holding device and of the element movable relative to it takes place, during which the at least one spring is relaxed and thus corresponding stored mechanical energy is released. The release device does not have to be on the outside as shown in FIG Rather, the triggering device can also be integrated in the central region of the holding device 5, for example. B Also other than mechanical embodiments of a triggering device are conceivable. In the illustrated case, the triggering device 8 has a recess. 12 with hook-like finish

In the tensioned state of the springs 9, the hook-like end 10 comprises the projection 6a of the holding device 5 The release device z B is designed so that at a in the image plane upward movement of the holding device 5, the hook-like end 10 of the projection 6a lost (s Fig 2) and relaxation of the springs 9a, 9b, a relative movement of the holding device 5 and the element 7 takes place In the exemplary embodiment, the holding device 5 moves down, along the line L to By a console 1 1 defined stop of the projections 6a, 6b is achieved by the movement of the holding device 5 down the module 3 is released from the free end of the coordinate measuring machine 1 and removed from this

If in this description of the exemplary embodiment of the above or below the speech, this is only the orientation with respect to the arrangement shown in Figures 1 to 9 The line L may in practice, however, extend in any direction, for example in the horizontal direction

As shown in Figure 1 and Figure 2, the movable member 7 has a hutformiges profile, wherein the opening of the hat is oriented upward The middle region of the element 7 is therefore located further down than the outwardly projecting portions where the Plunging springs 9 At the central region of the element 7, another elastic device, eg a spring 13, is supported. At its opposite end, the elastic device is supported on the bracket 11 or associated parts The element 7 is movable in the direction of the line L relative to the console 11 Such movements will be discussed in more detail (see FIGS. 6, 7 and 9). It can be seen in particular from FIGS. 1 and 7 and from FIG Element 7 has a recess 16 which cooperates with a second release device 15 so that the element 7 can be held in the cocked position of the elastic device 13 and upon actuation of the second release device 15, a movement of the element 7 upwardly relaxing the elastic device This transition from the tensioned to the relaxed state of the elastic device 13 is represented by FIGS. 8 and 9

At this point, reference should be made to a specific detail of the combination of the element 7 and the holding device 5, which in practice, however, can be configured differently. In the exemplary embodiment, the projections 6a, 6b of the holding device 5 extend through passage openings 30a, 30b in the Element 7 through outward

As already described, the transition from the state shown in FIG. 1 to the state shown in FIG. 2 is achieved by triggering the triggering device 8 and releasing the mechanical energy stored in the elastic device 9 Pulling force upward, along the line L are triggered z by the coordinate measuring machine 1 is moved accordingly Alternatively, the release device 8 by a reverse movement of the module 3 down along the line L or by a lateral movement in the plane of the figure 1 z B is drawn to the right or to the left Such a movement moves the module 3 z B only by one or two tenths of a millimeter

After the module 3 has been removed from the free end of the coordinate measuring machine 1, as shown in FIG. 2, the coordinate measuring apparatus 1 can be removed with its free end from the magazine location (as shown in FIG. 3)

In order to take over the module 3 again from the magazine location, in the exemplary embodiment shown here, the free end of the coordinate measuring machine 1 is positioned in the direction of the line L above the magazine location, as shown in Figure 4 downwardly projecting portions 31 of the coordinate measuring machine. 1 aligned so that upon movement of the coordinate measuring machine 1 in the direction of the line L to the magazine location to the projecting portions 31 abut on the element 7 on both sides of the module 3, as shown in FIG 5 is shown 6 shows the continued movement of the coordinate measuring machine 1 in the direction of the line L so that the elastic device 9 (in this case the helical springs) is tensioned, ie mechanical energy is stored in it. The final state of this movement of the coordinate measuring machine 1 is shown in FIG Note that not only the elastic means 9 but also the second elastic means 13 has been brought into the tensioned state by the movement of the coordinate measuring apparatus 1 along the line L. Accordingly, both the first release means 8 hold the holding means 5 in its cocked state relative to the first movable element 7 as well as the second release device 15 hold the element 7 in the cocked position relative to the console 11

In the state shown in FIG. 7, the module 3 is again in mechanical contact with the free end of the coordinate measuring machine 1 (as in the situation according to FIG. 1). If at least one permanent magnet is provided, the holding connection between the coordinate measuring device 1 and the module 3 maintain the HaiteverDinαung is already reached again in the state shown in Figure 7, while the module 3 is still held by the holding device 5

Now the coordinate measuring machine 1 moves the module 3 out of the holding device 5 by a movement transverse to the line L (eg by moving it vertically upwards to the image plane of Fig. 8). At the end of this lateral movement the coordinate measuring device 1 can move with the one of it module 3 optionally carry out a predefined movement (eg downwards or upwards in the direction of the line L), so that a weak force is exerted on the element 7, which leads to actuation of the second triggering device 15, as shown in FIG two different positions of the triggering device 15 is indicated, however, the draw of the triggering device can also be done in other ways, for example, electrically controlled

However, in any case, it is preferred that the triggering device 15 be actuated as soon as the coordinate measuring device 1 has removed the module from the holding device 5, so that the element 7 and the holding device 5 are in a position to release the energy stored in the elastic device 13 is brought and / or brought into a state in which again a module can be inserted into the holding device 5. This state, namely an elevated position of the element 7 and the holding device 5 with respect to the state shown in Figure 8 is shown in FIG Now, a device can again introduce a module 3 into the holding device 5, as shown in FIG

A second exemplary embodiment for a magazine location will now be described with reference to FIGS. 10 and 13. Identical or equivalent parts as in the first exemplary embodiment according to FIGS. 1 to 9 are designated by the same reference symbols. In the following, only the differences from the first exemplary embodiment will be described

The magazine location is in the state corresponding to FIG. 9 in the first exemplary embodiment, ie, the magazine location is ready to take over a module and to separate it from the device the module carries

In the embodiment shown in FIG. 10, the movable element 7 and the holding device 5 each have a region protruding in the horizontal direction. In these regions, the contact between the movable element 7 and the device takes place and between the module and the holding device Holding device 5 in this projecting portion of the recess 2, which allows the magazine space to pull the module from the device and hold the removal of the module is possible because the device abuts the top of the movable element 7 (Fig 13) and Thus, it can not move down while the holding device 5 moves with the module down The force of the tensioned springs 9 is dimensioned so that the holding force with which the device holds the module is overcome

10 shows a preferred principle of the invention, namely that the movable element 7 has a recess 21 in the projecting area into which the module to be transferred to the magazine location is introduced. The recess is shaped (here U-formιg) and arranged such that on the other hand, allows the edge of the recess 21, which is formed by the movable member 7, that the device, similar to that described with reference to Figure 5 to Figure 7 for the first exemplary embodiment, the movable element 7 can print down so as to establish contact between the device and the module The relative mobility between the movable element 7 and the holding device 5 is made possible by a guide (as shown in the embodiment of Fig. 10), for example, two vertically extending grooves 7c on the movable element 7 and corresponding projections (not shown in FIG. 10 recognizable) on the holding device 5, which engage in the grooves 7c.

The relative mobility between the movable member 7 and the bracket 11 is also made possible by a guide having (in the embodiment shown in Fig. 10) two vertically extending projections 11b on the opposing columnar portions 11a of the bracket 11, wherein the movable element 7 is located between the columnar regions 11a and thus can move in the vertical direction. Accordingly, the movable member 7 has two vertically extending grooves 7a, in which the projections 11b engage. In order to be able to recognize this guidance from FIG. 10, the upper part of the right-hand columnar region 11a of the console 11 is omitted, and only parts of its edges are shown by dashed lines.

FIG. 13 shows the corresponding side view of the arrangement according to FIG. 10, wherein an exchange plate with stylus is held by the magazine location. This state corresponds to the situation shown in the first embodiment in FIG. The device is still in mechanical contact with the adapter plate and the magazine position is about to deduct the adapter plate from the device down. Of the device arranged above the changeover plate, only the lower part 42 is shown for reasons of clarity of illustration in Fig. 13, which abuts the top of the movable element 7.

An exchange plate for interchangeable attachment to a coordinate measuring machine is shown in FIG. 11. The exchange plate 31 is a possible embodiment of a module 3, which can be transferred to a magazine location according to the invention and can be picked up again by the device. The exchange plate 31 has on its upper side from the prior art known elements 32 and shape design, which allow the precise, correct position and reproducible mechanical contact with a coordinate measuring machine. On its underside it has a cylindrical, downwardly extending projection 34 which merges into a larger diameter ring 35 at the bottom. In this case, the projection 34 and the ring 35 extend coaxially to the same vertical central axis. Therefore, the projection 34 forms a groove-like taper with a cylindrical outer periphery. The outer diameter of the cylindrical surface is smaller by the required clearance than the width of the In the embodiment of Figures 1 to 9, the recess 2 widens down to a wider zone In the embodiment of Figures 10 and 13, the recess 2, however, downwardly open and has only one Area that has the same width everywhere

At its lower end, below the ring 35, the projection 34 has an area of slightly smaller diameter than where the projection cooperates with the recess 2. At the lower, free end there is an opening 37 into which the upper end of a stylus or a different stylus can be used a complete measuring sensor 41, at the lower end 42 of the exchange plate 31 is coupled, wherein in the opening 37 of the exchange plate 31, a stylus 43 is inserted, Fig. 12 shows

In Figure 14, a retainer 55 and a movable member 57 of a further Ausfuhπjngsfo ^r m of the invention like ate Magazinpiatzes are shown whose function and mobility of the holding device 5 and the movable member 7 as shown in FIG 1 to FIG 10 corresponds Unlike the other embodiments, the recess However, the recess 52 is adapted to a corresponding groove 54 of a sensor, ie, the groove 54 and the recess 52 can cooperate such that the sensor 56 is held by the holding device 55. In this case, the recess 52 Similar to the previously described embodiments z B be open at the front, so that the sensor can be inserted through the opening into the recess and moved out of this The sensor 56 may have a complete Sensoπk for generating scanning signals ZB could the sensor shown in FIG 41 corresponding with a groove 54 are provided, so that the modified sensor can be received by a magazine magazine according to the invention
