Description

[0001] The invention relates to a bending device for automatically bending an air-conditioning pipe, preferably an air-conditioning hose, comprising a base body movable relative to a machine frame, on which at least one bending roller and at least one counter-holding roller are mounted in a motion-coupled manner, and a movement device for freely moving the base body within a horizontally oriented movement plane in the use position of the bending device, preferably by means of translational movements in two bidirectional spatial directions. Furthermore, the invention relates to a laying system for automatically laying an air-conditioning pipe on a reinforcement device with at least one such bending device.Furthermore, the invention relates to a method for automatically bending an air conditioning pipe by means of such a bending device and to a method for automatically laying at least one air conditioning pipe by means of such a laying system.

[0002] Conventionally, air conditioning pipes are bent using a bending mechanism in which a bending roller bends the air conditioning pipe by rotating around a securely positioned counter-roller to define a bending radius for the air conditioning pipe by pressing it against the counter-roller. The axis of the counter-roller defines the rotation trajectory, and the outer diameter of the counter-roller defines the bending radius of the air conditioning pipe. The bending roller can be moved independently of the counter-roller during the rotation trajectory. Such bending devices are known, for example, from DE 44 19 418 A1 and EP 4 029 621 A2.

[0003] A disadvantage of the state of the art is that the bending radius is limited by the geometry of the counter-holding roller, so that if a change in the bending radii for the air conditioning pipe is desired in a conversion process step, at least the counter-holding roller must be changed or the bending process of the air conditioning pipe is limited to a single bending radius of the air conditioning pipe.

[0004] Typically, air conditioning pipes are bent with a multitude of bends and stored in their entirety after the bending process. If necessary, they are manually secured—preferably via a mounting device for connection to separate equipment—to prevent unwanted slippage of the bent air conditioning pipe during post-processing steps. This is evident, for example, from documents EP 1 619 005 A2 and DE 10 2004 034 707 A1.

[0005] A disadvantage of the state of the art is that the connection of the air conditioning pipe is limited to the prefabrication of the air conditioning pipe and is restricted to boundary conditions that are not taken into account during the bending process - such as the geometry of the separate device - so that sufficient fixation of the air conditioning pipe cannot be guaranteed or at least requires complex additional manipulation steps in the connection.

[0006] The objective technical problem of the present invention is therefore to provide a bending device which is improved compared to the prior art, as well as a laying system and a method in which the disadvantages of the prior art are at least partially eliminated and which are characterized in particular by increased functionality via a particularly favorable arrangement of component parts on the bending device in order to increase flexibility and / or user-friendliness or to be able to cause a faster and more resource-efficient bending and / or laying process of air conditioning pipes.

[0007] This problem is solved by the features of claim 1.

[0008] It is therefore provided according to the invention that on the base body the at least one bending roller and the at least one counter-holding roller are adjustable in a relative positioning to one another on the base body and / or at least one connecting device for fastening the air conditioning pipe to a reinforcement device, preferably a reinforcement mat, is arranged in a movement-coupled manner with the at least one bending roller and the at least one counter-holding roller.

[0009] This makes it possible to avoid changing the counter-holding roller and, if necessary, adjusting the center distance between the counter-holding roller and the bending roller, while also allowing the bending radii of the air conditioning pipe to be adjusted quickly and easily in a continuous manner and at any time before, during or after the bending process.

[0010] In addition, there is the positive feature that the movement coupling between the connection device and the component parts involved in the bending process allows the air conditioning pipe to be fixed to the reinforcement device during the bending process, whereby a proper connection between the air conditioning pipe and the reinforcement device can be ensured.

[0011] In the context of the invention, the bending process can be interpreted as the introduction of a plurality of bending radii into the air conditioning pipe. Manual processing steps are generally not required in connection with the bending of a bending radius, the adjustment of the relative positioning between the at least one counter-holding roller and the at least one bending roller, or the fixation of the air conditioning pipe to the reinforcement device—particularly due to the shared movement coupling on the base body.

[0012] The bending radius for the air-conditioning pipe can be determined during the movement of the bending device and adjusted during the bending process. The bending radius can be defined by the spacing of the at least one bending roller and the at least one counter-holding roller, as well as, if necessary, by the movement trajectory—in particular, the relative movement of the at least one counter-holding roller and the at least one bending roller to the air-conditioning pipe.

[0013] In general, a rotational or pivoting movement of the at least one bending roller can be superimposed on a movement of the at least one counter-holding roller to bend the air conditioning pipe. The bending radius can be determined by the spacing, preferably distancing in the longitudinal direction of the base body, of the at least one bending roller and the at least one counter-holding roller and / or the movement sequence of the base body in the plane of movement. Limiting the bending radius to the outer diameter of the counter-holding roller is not necessary; the bending radius can be variably adjusted depending on the requirements of the air conditioning pipe by pressing the air conditioning pipe against the at least one counter-holding roller (defining a bending head) via the at least one bending roller.For example, a requirement for the air conditioning pipe that may need to be taken into account may be a spacing of reinforcing bars of the reinforcement device and / or a desired spacing of straight air conditioning pipe sections.

[0014] The spacing between the at least one bending roller and the at least one counter-holding roller can be adjusted by their relative positioning on the base body—particularly in the longitudinal direction. During a bend, it is not absolutely necessary for both the at least one bending roller and the at least one counter-holding roller to be arranged on the air conditioning pipe in a direction orthogonal to a neutral fiber of the air conditioning pipe.

[0015] According to the invention, it is possible to generate different bending radii with the same bending device during the bending process of the air conditioning pipe without having to force a production stop, wherein, for example, a first area of the air conditioning pipe has smaller bending radii (for more efficient air conditioning) and another area of the air conditioning pipe has larger bending radii (to conserve resources).

[0016] The adjustment of the bending radii of the air conditioning pipe and / or the number and / or positioning of fixing points of the air conditioning pipe on the reinforcement device can be flexibly automated.

[0017] The air conditioning pipe can generally be made of metal, wherein the air conditioning pipe is preferably designed in the form of an air conditioning hose made of plastic or plastic-like material for heating and / or cooling.

[0018] In the context of the invention, movement-coupled can be interpreted in such a way that when the base body moves in the direction of movement - in particular in the longitudinal direction along the machine frame - the at least one bending roller and / or the at least one counter-holding roller and / or the at least one connecting device are also moved at the same time, wherein in general, for example, at least during an adjustment process of the relative positioning to one another and / or a bending of the air conditioning pipe, a movement of the at least one bending roller and / or the at least one counter-holding roller and / or the at least one connecting device - in particular transversely to the direction of movement and / or longitudinal direction along the machine frame - can be provided that is decoupled from the movement of the base body.In general, the at least one bending roller can be fixed in the relative positioning to the at least one bending roller during a bending of the air conditioning pipe - in particular on the base body.

[0019] As stated at the outset, protection is also sought for a laying system for automatically laying an air conditioning pipe, preferably an air conditioning hose, on a reinforcement device, preferably a reinforcement mat, comprising at least one such bending device.

[0020] The longitudinal extent of the base body generally corresponds to the transport path of the base body with a region of the supply of air conditioning pipe at one end of the base body and the at least one bending roller at an opposite end of the base body, wherein the longitudinal extent corresponds parallel to the alignment along straight sections of the air conditioning pipe, wherein the bending radius or the radius of curvature for the air conditioning pipe can be adjusted by spatially distancing the at least one bending roller from the at least one counter-holding roller.

[0021] The base body can be regarded as a common movement device for coupling the movement of the at least one bending roller, the at least one counter-holding roller and / or the at least one connecting device in order to jointly transport the component parts or the entities involved in the bending process and / or laying process via the movement coupling in the sense of a shuttle, away from separate and independent devices.

[0022] Preferably, the movement coupling is in the transport direction of the base body. Particularly preferably, the at least one counter-holding roller and / or the at least one bending roller and / or the at least one connecting device are mounted on the base body as a common, one-piece base body, wherein the spacing of the at least one counter-holding roller and the at least one bending roller on this base body is variable.

[0023] As stated at the outset, protection is also sought for a method for automatically bending an air conditioning pipe by means of such a bending device, wherein the following method steps are carried out: the at least one bending roller and the at least one counter-holding roller are adjusted on the base body of the bending device in a relative positioning to one another on the base body and the air conditioning pipe is bent, preferably in the region of a reinforcement device arranged within a laying system, by pressing the air conditioning pipe via the at least one bending roller onto the at least one counter-holding roller, preferably with simultaneous translational movement and / or pivoting movement of the base body in the plane of movement, wherein it is optionally provided that the relative positioning of the at least one bending roller to the at least one counter-holding roller on the base body is changed during the bending process of the air conditioning pipe.

[0024] As stated at the outset, protection is also sought for a method for automatically laying at least one air conditioning pipe by means of such a laying system, wherein the following method steps are carried out: the at least one bending device is arranged relative to at least one reinforcement device arranged on the laying system, preferably in the use position of the laying system in the vertical direction below the at least one reinforcement device, the at least one bending device bends the at least one air conditioning pipe during a movement along the at least one reinforcement device and the at least one connecting device fastens the at least one air conditioning pipe to the at least one reinforcement device during the bending process of the air conditioning pipe, preferably at a plurality of fixing points.

[0025] Advantageous embodiments of the invention are defined in the dependent claims.

[0026] According to an advantageous embodiment of the invention, it is provided that the at least one connection device is designed in the form of an automated cable tying machine for fixing the air conditioning pipe by means of a cable tie, preferably made of metal or plastic, wherein it is preferably provided that the at least one connection device comprises a cable tie reel and / or a cable tie clip magazine.

[0027] For example, the cable tying machine comprises two gripper jaws that can be pivoted relative to one another, with which the air conditioning pipe can be gripped together with the reinforcement device. The gripper jaws press the air conditioning pipe against the reinforcement device, if necessary to contact the reinforcement device. Preferably, the gripper jaws are spaced apart from one another in an open position so that spacings between the air conditioning pipe and a reinforcement bar can be compensated for within the range of a diameter of the air conditioning pipe.

[0028] Preferably, the at least one connection device comprises a camera or sensor system for detecting a position of the air conditioning pipe and / or the reinforcement device. This is generally not necessary due to the movement coupling and / or relative arrangement to the at least one bending roller. Manual or downstream fastening of the air conditioning pipe to the reinforcement device is not necessary.

[0029] It is preferably provided that a pivoting drive is provided for rotating or pivoting the base body within the plane of movement.

[0030] By means of a swivel drive, the base body can be swiveled relative to the machine frame in addition to the movement device for positioning the bending device in such a way that the air conditioning pipe is bent.

[0031] Advantageously, in one embodiment of the invention, at least one drive device for adjusting the at least one bending roller relative to the at least one counter-holding roller and / or the at least one counter-holding roller relative to the at least one bending roller is arranged on the base body, wherein it is preferably provided that the spacing between the at least one bending roller and the at least one counter-holding roller can be changed by the at least one drive device during a bending process of the air conditioning pipe.

[0032] The at least one drive device can influence the bending radius of the air conditioning pipe by positioning the at least one bending roller relative to the at least one counter-holding roller.

[0033] The bending radius for the air conditioning pipe can be generated by the pivoting process via the pivot drive for a given spacing between the at least one bending roller and the at least one counter-holding roller, wherein in general a superposition of the movement of the base body caused by the pivot drive and the movement of the base body caused by the movement device can be used to define a bending radius - optionally in superposition with a pivoting movement of the at least one bending roller relative to the at least one counter-holding roller that is decoupled from the pivoting movement of the base body.

[0034] In general, it is also conceivable to use only the pivoting movement between the at least one bending roller relative to the at least one counter-holding roller to define the bending radius for the air conditioning pipe. Due to the multitude of movement mechanisms arranged on the base body and the usable degrees of freedom associated with the base body, the bending radius can be defined particularly flexibly via the spacing between the at least one bending roller and the at least one counter-holding roller.

[0035] Preferably, the at least one connection device comprises a drive means with which the at least one connection device can be pivoted and / or displaced relative to the base body independently of the at least one bending roller and the at least one counter-holding roller, although this is generally not absolutely necessary. Particularly preferably, the at least one connection device comprises a motor for opening and closing the at least one connection device.

[0036] In one embodiment of the invention, it has proven advantageous that the at least one bending roller and / or the at least one counter-holding roller is mounted rotatably or pivotably on the base body

[0037] This allows the bending radius for the air conditioning pipe to be set and / or the bending radius for the air conditioning pipe to be generated.

[0038] According to an advantageous embodiment of the invention, it is provided that the base body has a longitudinal extension parallel to a transport direction of the bending device oriented in the use position of the bending device, wherein the at least one bending roller and the at least one counter-holding roller are spatially spaced from one another along the longitudinal extension and / or can be adjusted in a spacing along the longitudinal extension.

[0039] The spacing in the longitudinal direction along the longitudinal extent of the base body oriented in the transport direction is to be distinguished from a general spacing between the at least one counter-holding roller and the at least one bending roller in the course of a bending process according to the prior art, since the spacing in the longitudinal direction is independent of the pivoting process of the at least one bending roller relative to the at least one counter-holding roller and does not concern the spacing between the at least one counter-holding roller and the at least one bending roller orthogonal to the longitudinal extent.

[0040] An advantageous variant is that the base body a feed device for transporting the air conditioning pipe relative to the base body is arranged, wherein it is preferably provided that the feed device comprises a plurality of driven transport rollers, and / or a sensor system is arranged for detecting a length of the air conditioning pipe moved relative to the base body, wherein it is preferably provided that the sensor system is designed as a rotary encoder, and / or a cutting unit is provided for severing the air conditioning pipe, wherein it is preferably provided that the cutting unit is arranged between the at least one bending roller and the feed device or the sensor system.

[0041] The feed device allows air conditioning pipe sections to be bent and laid to be continuously fed to the bending device. Preferably, the air conditioning pipe is straightened by the transport rollers before the bending process. Preferably, a straightening device separate from the transport rollers is provided, and / or the transport rollers function as a straightening device.

[0042] The sensors can detect a section of air conditioning pipe that has already been fed into the bending device, for example to cut the air conditioning pipe to length, bend it or connect it at a defined position.

[0043] The cutting unit allows a length of air conditioning pipe for a variety of reinforcement devices to be fed to the bending device from a storage device, such as a reel, without the need to interrupt the bending process due to the feeding of the air conditioning pipe to the bending device.

[0044] It is particularly preferred that the laying system at least one transport device, preferably in the use position of the laying system, which is translationally displaceable in the horizontal direction, for transporting the reinforcement device to the at least one bending device and / or at least one gripping device, preferably in the form of a traverse with at least one gripper, for holding the reinforcement device during a bending process of the air conditioning pipe and / or a reel for the air conditioning pipe to be bent.

[0045] The bending process can comprise carrying out a plurality of bends of the air conditioning pipe, wherein the transport device and / or the gripping device can efficiently integrate the bending process and the laying process into a production chain in which the semi-finished product is successively processed into a precast concrete component with the concrete cast around the reinforcement device together with the air conditioning pipe.

[0046] In one embodiment of the invention, it is provided that the at least one connecting device is arranged behind the at least one bending roller and the at least one counter-holding roller in the transport direction of the at least one bending device.

[0047] As a result, the air conditioning pipe can be secured essentially immediately after a bending process step and / or during transport of the base body along the reinforcement device. Alternatively or additionally, it can generally be provided that the at least one connection device is arranged upstream of the at least one bending roller and the at least one counter-holding roller in the transport direction.

[0048] According to a preferred embodiment of the invention, it is provided that the air conditioning pipe is bent during a translational movement and / or pivoting movement of the base body in the plane of movement and / or the at least one bending roller and the at least one counter-holding roller are moved in the plane of movement during the bending process of the air conditioning pipe.

[0049] Preferably, the bending process is carried out by relative pivoting of the at least one bending roller relative to the at least one counter-holding roller and / or the base body, wherein the at least one counter-holding roller can be moved relative to the base body or can be positioned stationary.

[0050] It has proven advantageous that in a process step preparatory to the bending process the reinforcement device is transported by a transport device to a gripping device and / or the reinforcement device is gripped by the gripping device and / or the transport device and the gripping device are moved vertically relative to each other in the use position of the laying system and / or the transport device is moved away from the gripping device or vice versa.

[0051] According to an advantageous embodiment of the invention, it is provided that during the fastening of the at least one air conditioning pipe, at least one cable binding machine encloses at least one reinforcing bar of the at least one reinforcing device and the at least one air conditioning pipe and automatically connects them to one another via at least one cable tie.

[0052] A separate holding device, which is positioned on the reinforcement device and adapted to the geometry of the air conditioning pipe, is therefore not required.

In general, the bending roller 4 or the counter-holding roller 5 can have its own means for changing the spacing between the bending roller 4 and the counter-holding roller 5.

[0079] The rotation means can be rotated or pivoted relative to the base body 3 as an alternative or in addition to changing the spacing between the bending roller 4 and the counter-holding roller 5 in order to carry out the bending process of the air conditioning pipe 2.

[0084] An exemplary method for automatically laying the air conditioning pipe 2 can be explained as follows: The bending device 1 is arranged relative to the reinforcement device 9 arranged on the laying system 24 in the use position of the laying system 24 in the vertical direction below the reinforcement device 9 (an alternative arrangement is generally possible), the bending device 1 bends the air conditioning pipe 2 during a movement along the reinforcement device 9 and the connecting device 8 fastens the air conditioning pipe 2 to the reinforcement device 9 during the bending process of the air conditioning pipe 2 at a plurality of fixing points 30 between the air conditioning pipe 2 and the reinforcement device 9.

[0085] The connection is preferably made via the connection device 8 in that, during the fastening of the air conditioning pipe 2, a cable binding machine 10 encloses at least one reinforcing bar 31 of the reinforcing device 9 and the air conditioning pipe 2 and automatically connects them to one another via a cable tie 11.

[0086] Fig. 3e differs from Fig. 3d merely in the sense that the bending device 1 is viewed from a different angle.

[0087] The connection device 8 comprises a cable tie reel 12 and a cable tie clip magazine.
