Definitions
- the present invention relates to a tool transport system for exchanging tools between a central tool magazine for storing a large number of tools and one or more machine tools.
- a method for exchanging tools on machine tools is proposed using a central tool magazine for accommodating a large number of different tools.
- EP 2 750 828 B1 describes a tool changing device on a tool magazine of a machine tool.
- the tool is used by means of a manipulator on a tool magazine that has one or more tool magazine wheels.
- the tool magazine itself is loaded manually.
- DE 10 2018 201 426 A1 discloses a feed device for tool magazines of a machine tool, which allows a tool or workpiece magazine to be loaded in a partially automated manner.
- an additional toolbar is provided, which can be populated manually by an operator.
- the tool bar with manually equipped tools can then be fed to a transfer position from the loading position that can be reached by the operator via a rotary lifting device of the feed device.
- a tool transport system for exchanging tools between a central tool magazine and one or more machine tools can at least comprise: a guided transport module for commuting between a central tool magazine and one or more machine tools along a transport path; a supporting guide for accommodating the transport module and for defining the transport path of the transport module, the transport module comprising a transport platform with at least one tool transport bar for accommodating a large number of tools, and the transport platform being spaced apart from the transport module in the vertical direction, preferably downwards.
- This arrangement and the use of the central tool magazine make it possible to efficiently change/replace a large number of tools from a central magazine on the machine tools without interrupting the machining cycles and without obstructing the space around the machine tool (horizontal access area to the machine tool). .
- the vertical tool feed combined with the central tool magazine and the rotatable transport platform is therefore an extremely efficient way of changing tools.
- the transport platform can preferably be designed to be rotatable about a vertical axis in order to change the spatial orientation of the tool transport bar.
- the transport platform can be used flexibly and efficiently for changing tools.
- the loaded bar can be rotated in the direction of movement for the translatory movement of the transport platform to enable safe and low-vibration transport of the tools.
- the rotation also makes it possible to use the rear of the transport platform for changing tools, e.g. using an additional tool transport bar. Loading and exchanging on a machine tool or the magazine is therefore possible with just one pendulum travel.
- a support frame for accommodating and rotatably mounting the transport platform can be provided and the support frame can preferably completely frame the transport platform in at least one plane for safe and low-vibration support.
- the support frame can be provided hanging on the transport module in order to enable improved access and thus quick tool changes.
- the transport module can have a first drive for moving along the transport path and a second drive for rotating the transport platform about a vertical axis.
- This configuration makes it possible to keep the drives small and to place them close to the movement axes in order to enable low-vibration and robust movements.
- these integrated drives are advantageously fed via the power supply on the rails in order to enable efficient energy transmission.
- a vertical movement of the transport platform itself is not provided in a preferred development (i.e. arrangement rigid in the vertical direction), so that the weight of the transport platform can be further reduced and the masses moved can therefore also be kept to a minimum.
- the supporting guide can be arranged at a vertical distance from the central tool magazine and/or the machine tools, with the supporting guide preferably being arranged at least partially above the central tool magazine and/or the machine tools (e.g. on the hall roof of a machine hall or on pillars which extend vertically over the machine tools extend out).
- the overhead arrangement makes it possible to freely transport the tools over the machine tools, preferably with them minimal transport distances to control the machine tools directly for the tool change.
- the supporting guide can comprise at least one rail on which guide means of the transport module engage, the transport module being displaceable and preferably only being mounted on the supporting guide.
- the rails advantageously establish a direct path between the tool magazine and the machine tool in order to enable efficient tool transport. Reaching in and storing the transport module only on the rails enables efficient assembly and quick tool transport with reduced energy consumption.
- the transport platform can have a first tool transport bar and a second tool transport bar, preferably arranged opposite one another (preferably spaced apart and parallel to one another).
- Each tool transport bar can have a plurality of transport mounts for storing tools in a loading direction.
- the loading direction of the first and second tool transport bar can be configured in opposite directions.
- the transport platform can be accommodated on a bearing shaft and the bearing shaft can be journalled on the support frame, the second drive being connected to the bearing shaft by means of engagement means and rotating the bearing shaft in order to rotate the transport platform. This enables efficient and low-vibration turning of the transport platform.
- the supporting guide can have stops along the transport path, which each have the central tool magazine and the at least one Machine tool are assigned and where the transport module stops for exchanging tools.
- the transport module can advantageously be a shuttle car with castors for fast travel, comprising a self-propelled drive that drives the transport module along the rails of the supporting guide, and the self-drive is in particular the first drive.
- a production system can have at least one machine tool, a central tool magazine for storing tools and a tool transport system.
- the central tool magazine and the at least one machine tool can each include a tool supply bar that can be moved into a transfer position for changing tools with the tool transport bar of the transport module.
- the tool delivery bar can be moved vertically upwards into the transfer position and back, and the tool delivery bar can be set up to carry out an upward or downward stroke movement in order to transfer the tools to the tool transport bar in the transfer position.
- the disclosure of DE 10 2018 201 426 B1 and AKZ DE 10 2020 211672.5 is hereby incorporated by reference.
- the tool transport bar can advantageously be set up to move into an overlapping position with the tool supply bar, so that tool grippers of the tool transport bar and are arranged one above the other.
- a method for exchanging tools between a central tool magazine and one or more machine tools with a tool transport system wherein the central tool magazine and the at least one machine tool each have a tool supply bar and the tool transport system comprises: a guided Transport module with at least one tool transport bar and a supporting guide for receiving the transport module and for defining the transport path of the transport module, can comprise the steps of: commuting the transport module between stops of the transport path at a central tool magazine and one or more machine tools along a transport path; Exchange of tools at the stops by a lifting movement of the tool supply bar.
- the following steps can advantageously be provided: moving the tool delivery bar vertically upwards into a transfer position and then preferably moving the tool transport bar into an overlapping position with the tool delivery bar; and to transfer the tools to the tool transport bar in the transfer position, performing an up-stroke movement or a down-stroke movement of the tool staging bar; and/orrotating the transport platform about a vertical axis in order to change the spatial orientation of the tool transport bar for exchanging the tools.
- FIG. 1 shows a first overview of the tool transport system with the transport module (P);
- FIG 2 shows another illustration of the tool transport system, with the transport platform being in the neutral position (tool transport bar (E2) is at right angles to the transport path along the rails);
- FIG. 3 shows a detailed illustration of the transport module with the transport platform (PT);
- FIG. 4 shows an overview of a central tool magazine and the tool transport system arranged above it
- FIG. 5 shows a further representation of the tool transport system, which is arranged above the central tool magazine and the individual machine tools;
- FIG. 6 shows a side view of the tool transport system above the central tool magazine and the machine tool
- FIG. 8 shows a plan view of the tool transport system with the machine tools and a central tool magazine
- Fig. 9 shows the transport platform (PT) in a rotated position relative to the track
- the tool transport system for exchanging tools between a central tool magazine ZWM and a machine tool WZM is shown.
- the tool transport system includes a transport module P, which is also referred to as a shuttle module.
- the pendulum module has its own drive and can be moved along the supporting guide F in a translatory manner.
- the transport module P also has a transport platform PT, which is attached to the transport module P in a suspended manner.
- the transport platform PT is therefore only preferably fixed on a single side and the other sides are free.
- the supporting guide F is arranged via a horizontal carrier F3 and a vertical carrier F4 in the area above the machine tool WZM or the central tool magazine ZWM.
- This overhead arrangement with respect to the machine tool and the central tool magazine makes it possible to use the transport module P to transport the corresponding tools via the individual machine tools and the central tool magazine, preferably on a direct route. This keeps the work area around the machine tools and around the central tool magazine free to enable the tools to be changed efficiently without interrupting the machining cycles.
- the supporting guide F is preferably arranged with a first and a second rail F1 and F2 in the vertical direction higher than the upper end of the individual machine tools and/or the central tool magazine.
- the transport module P is therefore also further away relative to the floor on which the machine tool and the tool magazine are provided than the upper end of the individual machine tools and the central tool magazine.
- the supporting guide F has a first rail F1, which is designed, for example, as an I-profile support, and a second rail F2, which is preferably also designed as an I-profile support.
- the transport module P can be provided on the underside of these rails, in the direction of the workshop floor, via sliders or rollers, so that the transport module P can slide or roll along the rails.
- the guide surfaces of the rails are preferably directed in the direction of the workshop floor or floor.
- the supporting guide F comprises a profile beam, which is arranged along the transport path, with a rail being fixed to the underside.
- Two profile supports are preferably provided, with each profile support being assigned its own rail, namely the first rail F1 and the second rail F2, which preferably run parallel to one another along the transport path.
- the profile supports of the load-bearing guide F are preferably firmly connected to one another via struts F6, so that there is a distance between the supports or between the first rail Fl and the second rail F2 is constantly guaranteed over the entire transport route.
- the supporting guide F with the profile carrier is also set up to absorb the entire weight force and loading force of the transport module P, which is provided hanging on the rails.
- the profile supports are in turn firmly connected to the horizontal support F3, for example via a screw connection or a welded connection.
- All structural components of the transport module P and in particular the transport platform PT are preferably arranged in the vertical direction below the supporting guide F.
- the suspended arrangement of the transport module P also allows safe and easy access to the slides or rollers of the transport module P, which are engaged with the rails, so that efficient maintenance becomes possible.
- Particularly preferably, only one toothed rack F5 is provided, which is provided along the first rail F1 and which has markings for position detection by the transport module P.
- the transport module P therefore particularly preferably always autonomously detects its own position along the transport path.
- the supporting guide F which is attached to the horizontal support F3 via the profile supports, is preferably designed in such a way that the horizontal support F3 is only fixed on one side to a vertical support F4, so that the connected supports F3 and F4 form an L-shape.
- the two supports are preferably welded to one another, with the vertical support F4 being screwed to the workshop floor opposite the connection point of the vertical support F4 to the horizontal support F3.
- This carrier configuration is preferably provided at least at each stop of the transport module P along the transport route. This ensures a stable tool transfer from Transport module P to the respective machine tool or the central tool magazine, which are assigned to the stop Hl, H2, H3, H4. In particular, mechanical vibrations that can arise during the transfer process can be efficiently absorbed, so that a safe and precise transfer of the tools can be achieved.
- the transport module P is provided hanging on the underside of the supporting guide F.
- the means of engagement such as sliders or rollers of the transport module P, engage on the rails of the supporting guide F, so that the transport module P can be slidably mounted on the rails or the profile supports of the supporting guide F.
- the transport module P is designed to be movable in translation along the rails, and this movement can be controlled particularly advantageously by the first drive A1.
- the first drive Al is attached directly to the transport module B and preferably has a horizontal orientation.
- the first drive A1 can engage in the toothed rack F5 via corresponding gear wheels in order to achieve a forward or backward movement of the transport module B along the transport path.
- the energy is transmitted to the first drive, for example, via appropriate cable connections, which are provided on the profile carrier and can be carried along with the transport module B accordingly.
- the energy is advantageously transmitted via a driver which is ground along the rails.
- energy can be transmitted without contact, for example inductively.
- the first drive A1 is therefore preferably provided on the upper side of the transport module P, directly next to a rail of the supporting guide F.
- a second drive A2 is provided on the same side and preferably next to the first drive A1, which preferably has a vertical alignment of the longitudinal axis and which is provided in order to carry out a rotary movement of the transport platform PT.
- the transport platform PT has the tool transport bar E2, in which a large number of tools W can be used. In the example shown in Fig. 1, eight tools W in a tool transport bar E2 be used. Opposite the tool transport bar E2 shown is another tool transport bar, which in turn can accommodate a large number of tools W.
- the transport platform PT is designed to be rotatable via the second drive A2, so that the orientation of the tool transport rail can be determined relative to the transport path or to the longitudinal direction of the rails.
- a first or a second tool transport bar E2 can be arranged such that this is at the front of the transport module and therefore in the direction of movement along the transport path.
- a rotation of the transport platform PT can also be used to rotate a tool transport bar E2 in such a way that it is arranged to the rear of the transport module P, ie opposite to the direction of movement along the transport path.
- the transport platform PT When driving to a corresponding stopping point with the aim of handing over tools, it is therefore possible to use the rotary movement of the transport platform PT to set up corresponding tool locations on the tool transport bar E2 for contact with the receiving device of the machine tool WZM or the central tool magazine ZWM.
- the rotary movement of the transport platform PT also enables tools W to be exchanged and exchanged between two stopping points in just one pendulum movement of the transport module P.
- a first tool transport bar E2 can be used to exchange appropriate tools W; and for exchanging tools, the transport platform PT can be rotated in such a way that the second tool transport bar E2 is moved into the contact area with the transfer unit of the machine tool WZM or the central tool magazine ZWM. It is therefore not necessary for the transport module P to move repeatedly between two stopping points for a changing and simultaneous changing operation.
- the rotatable transport platform PT When approaching a stopping point, the rotatable transport platform PT therefore makes it possible, for example, to place tools in the first tool transport bar E2*. to change and to exchange tools from the second tool transport bar E2, so that maximum flexibility and efficiency can be achieved in the tool changing process.
- the rotational movement of the transport platform is particularly preferably controlled directly by the transport module controller PS, which is provided directly on the transport module P.
- the transport module controller PS which is provided directly on the transport module P.
- the support frame PR is designed in such a way that it encloses the transport platform PT and preferably at least frames it in one plane. This frame serves as a stabilization and support mechanism for the rotating transport platform PT.
- the rotatable transport platform PT is rotatably mounted on the support frame PR via a rotary shaft.
- the transport module controller PS is provided on the lateral support frame PR.
- the transport module P is shown in the engaged position with the tool supply bar of the machine tool WZM.
- the machine tool WZM has a tool lift El with a loading bar E1B, which can be moved vertically upwards.
- the tools held vertically in the tool transport bar E2 can be lifted out of the tool transport bar E2 by a lifting movement of the tool lift of the machine tool, or they can be inserted into this tool transport bar E2 by a downward lifting movement.
- a lifting movement of the transport module P can thus be avoided.
- FIG. 1 A further illustration of the tool transport system is shown in FIG.
- the transport platform PT shown has a central middle piece which connects the top to the bottom of the transport platform PT.
- This central platform receptacle PT2 is therefore arranged in such a way that the axial extension is aligned with the axis of the transport platform PT.
- laterally spaced side platform mounts PT1 are located to the right and left of the central platform mount PT2. Both the central platform mount PT2 and the lateral platform mounts PT1 open out together at an upper connecting section and a lower connecting section. In the intermediate area, the openings PT3 are provided for optimizing the vibration of the transport platform PT and for further weight savings.
- the tool transport rails E2, E2* are provided on the lower attachment section, which are preferably directly connected to the attachment section on the underside with the lateral platform mount and the central platform mount PT1, PT2.
- the transport platform also has a rotary shaft PTL protruding in the vertical direction at the top and at the bottom of the transport platform PT. These protruding portions form a rotary shaft.
- this rotary shaft On the underside of the transport platform PT, this rotary shaft has a lower rotary axis section PT4 for receiving and supporting the transport platform PT, and on the upper side of the transport platform PT an upper rotary axis section PT5 for the rotary track mounting of the transport platform PT and for absorbing the axial forces, such as weight forces.
- the rotary shaft of the upper and lower rotary axis section opens into respective rotary shaft receptacles of the support frame PR. These recordings of the support frame PR allow a rotary movement of the rotary shaft.
- the rotary shaft can also be referred to as a storage shaft PTL, since this storage of the Transport platform PT is achieved and at the same time a rotational movement about the storage shaft axis is made possible.
- the support shaft axis is a vertical axis.
- the support frame PR includes two opposite side supports PR1 and PR2. These side supports are each designed as a cross-section that tapers, and therefore becomes smaller in the direction of the workshop floor, as a support or as a profile. On the underside of the side supports PR1 and PR2 there is a lower support bracket PR4 which firmly connects the first and second side supports PR1 and PR2 to one another. On the upper side of the side supports PR1 and PR2 is the upper support PR3, which firmly connects the side supports PR1 and PR2.
- the transport module controller PS is preferably provided on the outer side surface of the side support PR2, which can be used to control the first and second drives and to detect the position of both the rotational position of the transport platform and the position of the transport module along the transport path.
- the 2 also shows the L-shaped support arrangement with the vertical support F4 and the horizontal support F3 fastened thereon.
- the support assembly receives the supporting guide at the top.
- the transport module P provided on the rails via the sliders is firmly connected to the support frame PR, which is firmly fixed to the sliders hanging downwards.
- the axis of rotation of the bearing shaft PTL is also provided between the sliders of the transport module P in order to enable the transport platform PT to rotate with as little vibration and as effectively as possible.
- FIG. 3 shows a detailed view of the transport module P.
- the rail sliders S are located on the upper side of the transport module and serve to mount the entire transport module P on the rails.
