HANDLING DEVICE WITH DEFINED REST CONFIGURATION

Description

[0001] The invention relates to a handling device for handling and, if necessary, transporting objects.

[0002] In production or logistics environments, there are often a large number of handling stations where objects must be moved, for example, from a storage rack onto a pallet. Hand-held handling devices can be used to move the objects, allowing for a high degree of flexibility during loading. Hose lifters with suction grippers arranged at the end of a lifting hose can be used as lifting aids. Crane-like constructions are also known. EP289042A1, for example, describes a stationary lifting aid in which a suspension cable is guided along a horizontally aligned, laterally pivoting boom. A vacuum gripper can be arranged on the suspension cable to secure the objects to the device. After picking up the objects, the operator can manually move them to their destination and set them down there. Industrial trucks are often used to move objects over longer distances, e.g.Forklifts. When objects are loaded from the industrial truck into storage areas or handling stations, problems can arise due to the space requirements of the handling equipment used or poor positioning of the handling equipment. In particular, considerable maneuvering effort can be required if the handling equipment is stationary.

[0003] Handling devices are known from US 2018 / 182658 A1, US 2018 / 086489 A1, US 2018 / 043529 A1, US 2018 / 354136 A1, DE 295 08 758 U1 and EP 0 189 356 A2, with a vertically extending support and with a horizontally extending arm rotatably and / or displaceably arranged on this support.

[0004] The object of the present invention is to provide a handling device which can be operated comfortably and can be moved easily and safely between different locations.

[0005] The object is achieved with a handling device having the features of claim 1. The handling device comprises a support which, during intended operation of the handling device, extends along a vertical support axis. A first cantilever member is arranged on the support and is non-rotatable and non-displaceable, extending in a first cantilever plane transverse to the support along a first cantilever direction. The cantilever plane is preferably arranged orthogonally at an angle of 90° to the support. The first cantilever member can in particular have a first end section which is screwed, welded, or otherwise connected to the support. The first cantilever member is preferably not adjustable in length and / or not telescopic. In particular, the first cantilever member is rigidly connected to the support.

[0006] A second cantilever member is pivotally mounted on the first cantilever member in a second cantilever plane by means of a first joint. The first joint is preferably designed as a first rotary joint with a single degree of freedom, wherein it is rotatable about a first axis of rotation running parallel to the support axis. The first joint can comprise ball or cylindrical roller bearings. The first joint and the second cantilever member are arranged in particular at a second end section of the first cantilever member. The second end section is arranged opposite the above-mentioned first end section of the first cantilever member. The second cantilever member can also have a first end section and a second end section, wherein the first end section of the second cantilever member is assigned to the second end section of the first cantilever member.

[0007] A third cantilever member is pivotally mounted on the second cantilever member in a third cantilever plane by means of a second joint. The second joint is preferably designed as a rotary joint with a single degree of freedom, wherein it is rotatable about a second axis of rotation running parallel to the support axis. The second joint can preferably comprise ball or cylindrical roller bearings. The second joint and / or the third cantilever member is arranged in particular at a second end section of the second cantilever member. The second end section is arranged opposite the first end section of the second cantilever member. The third cantilever member can have a first end section and a second end section, wherein the first end section of the third cantilever member is assigned to the second end section of the second cantilever member.

[0008] A connecting section for coupling a lifting and / or gripping device is provided on the third cantilever member. The connecting section is preferably arranged opposite the first end section of the third cantilever member.

[0009] The first joint and the second joint are configured such that, along the support axis, the first cantilever plane lies above the second cantilever plane, and the second cantilever plane lies above the third cantilever plane. The first cantilever member, the second cantilever member, and the third cantilever member are thus arranged in a cascade or descending step-like manner. Furthermore, the cantilever members and / or the joints are configured such that the first cantilever plane, the second cantilever plane, and / or the third cantilever plane are each parallel to one another and / or such that the first cantilever plane, the second cantilever plane, and / or the third cantilever plane are each orthogonal to the support axis.

[0010] The joints and the cantilever members are designed such that the second cantilever member can pivot beneath the first cantilever member, and that the third cantilever member can pivot beneath the second cantilever member and beneath the first cantilever member. The first joint is preferably designed such that the second cantilever member can pivot as desired by more than 360° about the first axis of rotation. The second joint is preferably designed such that the third cantilever member can pivot as desired by more than 360° about the second axis of rotation. The pivoting of the cantilever members enables a high degree of freedom of movement for a coupled lifting and / or gripping device. In a plane parallel to the third cantilever plane, the lifting and / or gripping device can therefore be moved almost as desired.Due to the rigid attachment of the first cantilever member to the support, easy operability of the handling device is achieved since the range of movement of the cantilever members is shifted and / or limited along the cantilever direction.

[0011] A locking device is preferably provided on the support and / or on the first cantilever member, in which the third cantilever member can be fixed in a rest configuration. The third cantilever member preferably has a locking section associated with the locking device. The locking device and the locking section are preferably designed and arranged in such a way that they are coordinated with one another and such that the locking section can be fixed in the locking device, thereby predetermining the clearly defined rest configuration for the second cantilever member and the third cantilever member.

[0012] For mobile handling devices with movable links, care must be taken when moving the entire handling device to ensure that the links do not extend too far to the side or even deflect sideways. The rotationally and displacement-resistant arrangement of the first cantilever link and the ability to secure the second and third cantilever links using the locking device and locking section enable a compact rest configuration, as explained in more detail below.

[0013] An advantageous development of the invention provides that the connecting portion and / or the locking portion is arranged on the second end portion of the third cantilever member, wherein the second end portion of the third cantilever member faces away from the second joint. If the connecting portion and the locking portion are arranged on the second end portion of the third cantilever member, a consistent location for coupling the lifting and / or gripping device is provided in the region of the locking device in the rest configuration.

[0014] Advantageously, the first cantilever member has a first length, the second cantilever member a second length, and the third cantilever member a third length. The first length corresponds to the distance between the support and the first joint along the cantilever direction. The second length corresponds to the distance between the first joint and the second joint. The third length corresponds to the distance between the second joint and the connecting section. It is advantageous if the sum of the second length of the second cantilever member and the third length of the third cantilever member is greater than the first length of the first cantilever member. In the rest configuration, the second joint is preferably located laterally next to the first cantilever member. It is conceivable that in the rest configuration, the second joint is located laterally next to the first cantilever member and behind the first joint along the cantilever direction.

[0015] In the rest configuration, the second joint is located between the support and the first joint, viewed along the extension direction of the first cantilever member, but is offset orthogonally to the cantilever direction next to the first cantilever member. This allows for the realization of a boom with a great length and span that requires little lateral space in its rest configuration. Preferably, in the rest configuration, the second cantilever member and the third cantilever member form an angle between 30° and 180°, preferably an obtuse angle, with each other at the second joint.

[0016] It is advantageous if the first length of the first cantilever member is longer than the second length of the second cantilever member and / or longer than the third length of the third cantilever member. Furthermore, it is advantageous if the third length of the third cantilever member is longer than the second length of the second cantilever member. The shorter design of the movable cantilever members ensures smooth handling of the handling device by the operator.

[0017] In an advantageous further development, the connecting section and / or the locking section of the third cantilever member is offset upwards along the support axis. Preferably, the connecting section and / or the locking section is located in the second cantilever plane or above the second cantilever plane, i.e. on the side of the second cantilever plane opposite the third cantilever plane. Accordingly, a lifting and / or gripping device can be arranged as high as possible on the connecting section without the installation space of the entire handling device having to be increased. If, for example, a hose lifter with a long stroke length is to be coupled to the connecting section, it can thus be ensured that the gripping element with a minimum length does not hang too low in the retracted configuration of the hose lifter.In this context, it is advantageous if a distance along the third cantilever member between the second joint and the connecting portion and / or the locking portion is greater than or equal to the second length of the second cantilever member. This allows the third cantilever member to be pivoted completely beneath the second cantilever member, even if the connecting portion and / or the locking portion of the third cantilever member is offset upward along the support axis.

[0018] The support is designed as a column extending along the support axis, which is particularly height-adjustable and, furthermore, particularly telescopic. Consequently, a lifting and / or gripping device to be coupled is movable in all three spatial directions X, Y, and Z. This provides a high degree of flexibility for the operator when handling the device.

[0019] A further development of the invention provides that the handling device comprises a base housing with a central longitudinal axis running parallel to the cantilever direction and with a transverse axis running orthogonal to the central longitudinal axis and parallel to the first cantilever plane. The support is preferably arranged off-center with respect to the central longitudinal axis on the base housing, in particular in a rotationally and / or displacement-resistant manner. In this respect, the support is arranged on the base housing at a distance from the central longitudinal axis along the transverse axis. Accordingly, the handling device can be easily driven under and moved by an industrial truck.

[0020] It is advantageous if the locking device is arranged on a side of the support and / or the first cantilever member facing the central longitudinal axis. Furthermore, it is advantageous if both the locking device and the locking section are arranged in the second cantilever plane. Consequently, it is obvious for the operator to arrange the second cantilever member and the third cantilever member in the rest configuration between the central longitudinal axis and the first cantilever member.

[0021] Advantageously, the locking device and / or the locking section is configured such that the locking section can be locked into the locking device along a movement path coming from the central longitudinal axis. In this respect, the lateral space required for pivoting the boom into the rest configuration is kept as small as possible. The operator can lock the second cantilever member and the third cantilever member into the rest configuration, preferably only coming from the central longitudinal axis. In the rest position, the second joint is then preferably located laterally next to the first cantilever member, in particular on the side of the first cantilever member facing the central longitudinal axis. The first cantilever member and the second cantilever member form an acute angle with one another at the first joint. As a result, the rest configuration is assumed without forming a laterally projecting interfering contour.It is also conceivable for the second cantilever member and the third cantilever member to be significantly longer in total than the first cantilever member. In this case, the second joint can be located between the first cantilever member and the central longitudinal axis in the rest configuration, or between the first cantilever member and another longitudinal axis that runs parallel and off-center to the central longitudinal axis relative to the support. This also ensures that the second cantilever member and the third cantilever member do not form a laterally protruding interference contour in the rest configuration.

[0022] In a further development of the invention, the base housing has at least one tine receptacle for at least one tine of a fork of an industrial truck, wherein the tine receptacle is designed in particular in the manner of a tine overshoe. The base housing and / or the tine receptacle is preferably designed such that the industrial truck can pass underneath the base housing and the at least one tine can be inserted into the at least one tine receptacle. This enables easy transport of the handling device by means of the industrial truck.

[0023] The base housing preferably contains a power source, which is designed in particular as a replaceable and / or rechargeable battery. The battery can be easily inserted into or removed from the base housing.

[0024] A vacuum pump can also be arranged in the base housing. The support, the first cantilever member, the second cantilever member, and the third cantilever member preferably have channels, in particular internal channels, for conveying media and / or data between the vacuum pump and the connecting section. Furthermore, the support, the first cantilever member, the second cantilever member, and the third cantilever member can be designed as hollow profiles, with the internal cavities of the hollow profiles forming said channels. This provides an internal pressure control system for a connectable lifting and / or gripping device, and prevents interference caused by hoses.

[0025] In a further development of the invention, at least one support leg is provided on the base housing, which can be adjusted parallel to the support axis into a lower support position along the support axis and into an upper release position along the support axis. In the support position, the load acting on the handling device can be guided into the ground via the at least one support leg. In the upper release position, the handling device can be moved without the at least one support leg touching the ground.

[0026] It is advantageous if the at least one support leg is configured such that the at least one support leg moves into the upper release position when the locking section is secured in the locking device and / or when an industrial truck has driven under the handling device. It is further advantageous if the at least one support leg is configured such that the at least one support leg moves into the lower support position when the locking section is released from the locking device. Preferably, a control device is provided which is configured to move the support position into the upper release position and the lower support position. Accordingly, the at least one support leg can be moved automatically into the respectively optimal position. The control device can in particular be arranged in the base housing or on the connection section.

[0027] Advantageously, the handling device comprises a lifting and / or gripping device arranged at the connecting section of the third cantilever member. The lifting and / or gripping device is preferably designed as a hose lifter, comprising a lifting hose that can be shortened by applying negative pressure, and a suction gripping device arranged at the free end of the lifting hose for suctioning up an object to be lifted. The vacuum supply required for operation of the lifting hose and the suction gripping device is preferably provided through internal channels in the cantilever members and, in particular, also through internal channels in the support.

[0028] Further details and advantageous embodiments of the invention can be found in the following description, on the basis of which various embodiments are described and explained in more detail.

[0030] In the Fig. 1 bis 3 a handling device 10 is shown which comprises a support 14 extending along a support axis 12 which, during normal operation of the handling device 10, is vertical. The support 14 is designed as a column 14 which is telescopic and therefore height-adjustable. A first cantilever member 16 is arranged on the support 14, which is fastened to the support 14 in a rotationally and displacement-proof manner and which extends in a first cantilever plane 18 along a first cantilever direction 20. The first cantilever plane 18 and the first cantilever direction 20 each run orthogonally, at an angle of 90° to the support axis 12. The first cantilever member 16 has a front first end section 22 and a rear second end section 24. The first cantilever member 16 is connected to the support 14 in the front first end section 22.

[0031] A first pivot joint 26 is arranged at the rear second end section 24 of the first cantilever member 16. The pivot joint 26 is rotatable about a first axis of rotation 28, wherein the axis of rotation 28 runs parallel to the support axis 12. The first pivot joint 28 comprises cylindrical roller bearings 29. The first pivot joint 28 is shown in detail in Fig. 3a visible. By means of the first pivot joint 26, a second cantilever member 30 is pivotally mounted on the first cantilever member 16.

[0032] The second cantilever member 30 is pivotable about the rotation axis 28. The second cantilever member 30 extends in a second cantilever plane 32 along a second cantilever direction 34. The second cantilever member 30 has a front first end section 36 and a rear second end section 38, wherein the first end section 36 is assigned to the first pivot joint 26. At the first end section 36, the second cantilever member 30 has a first joint section 31 running along the first rotation axis 28, which leads from below into the first pivot joint 26 and is enclosed by the cylindrical roller bearings 29.

[0033] A second pivot joint 40 with a second pivot axis 42 is arranged at the second end portion 38 of the second cantilever member 30, wherein the second pivot axis 42 runs parallel to the support axis 12 and the first pivot axis 28. The second pivot joint 40 also includes cylindrical roller bearings 29.

[0034] A third cantilever member 44 is pivotably mounted on the second cantilever member 30 by means of the second pivot joint 40. The third cantilever member 44 is pivotable about the second pivot axis 42. The third cantilever member 44 extends in a third cantilever plane 46 along a third cantilever direction 48. The third cantilever member 44 has a front first end section 50 and a rear second end section 52, wherein the first end section 50 is assigned to the second pivot joint 40. At the first end section 50, the third cantilever member 44 has a second joint section 45 running along the second pivot axis 42, which leads from below into the second pivot joint 40 and is enclosed by the cylindrical roller bearings 29.

[0035] At the rear second end portion 52 of the third cantilever member 44, a connecting portion 54 is provided for coupling a lifting and / or gripping device 55.

[0036] The first pivot joint 26 is designed such that according to Fig. 3a along the support axis 12, the first cantilever plane 18 lies above the second cantilever plane 32. The second pivot joint 40 is designed such that along the support axis 12, the second cantilever plane 32 lies above the third cantilever plane 46. The first pivot joint 26 and the second pivot joint 40 are designed such that the first cantilever plane 18 lies above the third cantilever plane 46. Furthermore, the pivot joints 26, 40 and the cantilever members 16, 30, 44 are designed such that the first cantilever plane 18, the second cantilever plane 32, and the third cantilever plane 46 each run parallel to one another.

[0037] Especially in Fig. 3a It can be seen that the second cantilever member 30 can pivot beneath the first cantilever member 16. The third cantilever member 44 can pivot beneath the second cantilever member 30. The first pivot joint 26 and the second pivot joint 40 are designed such that the second cantilever member 30 and the third cantilever member 44 can pivot as often as desired by more than 360° about the first axis of rotation 28 and the second axis of rotation 42, respectively.

[0038] Especially in Fig. 2 The length ratios of the cantilever members 16, 30, 44 are evident. The first cantilever member 16 has a first length 60, which is measured from the distance between the support 14 and the first pivot joint 26. The second cantilever member 30 has a second length 62, which is measured from the distance between the first pivot joint 26 and the second pivot joint 40. The third cantilever member 44 has a third length 64, which is measured from the distance between the second pivot joint 40 and the connecting section 54.The first cantilever member 16, the second cantilever member 30 and the third cantilever member 44 are designed such that the first length 60 of the first cantilever member 16 is each greater than the second length 62 of the second cantilever member 30 and the third length 64 of the third cantilever member 44, that the third length 64 of the third cantilever member 44 is greater than the second length 62 of the second cantilever member 30 and that the sum of the second length 62 and the third length 64 is greater than the first length 60.

[0039] A locking device 56 is provided on the first cantilever member 16. The third cantilever member 44 has a locking portion 58, which is arranged on the rear second end portion 52 of the third cantilever member 44 and is assigned to the locking device 56. The locking device 56 and the locking portion 58 are designed and arranged in such a way that the locking portion 58 can be fixed in the locking device 56 and thereby a clearly defined rest configuration for the second cantilever member 30 and the third cantilever member 44 can be specified. Such a rest configuration is shown in the Fig. 5 , 6 and 7 .

[0040] The connecting section 54 and the locking section 58 are offset upwards along the support axis 12. Accordingly, it can be ensured that a lifting and / or gripping device 55 to be coupled is arranged as high as possible and, for example, does not hang too low in a retracted configuration. The connecting section 54 is provided above the second cantilever plane 32 and below the first cantilever plane 46. The locking section 58 is provided in the second cantilever plane 32. Since the third length 64 is greater than the second length 62, the third cantilever member can be pivoted below the second cantilever member 30 despite the upwardly offset connecting section 54 and the upwardly offset locking section 58. In addition, the locking device 56 is also arranged in the second cantilever plane 32, so that the locking section 58 can be secured in the locking device 56.

[0041] In the Fig. 4 bis 8 A further embodiment of a handling device 10 according to the invention is shown, which further comprises a base housing 66. The base housing 66 has a central longitudinal axis 68 running parallel to the first projection direction 20 and a transverse axis 70 running orthogonal to the central longitudinal axis 66 and parallel to the first projection plane 18. The support 14 is arranged eccentrically with respect to the central longitudinal axis 66 on the base housing in a rotationally and displacement-resistant manner.

[0042] The locking device 56 is arranged on a side of the first cantilever member 16 facing the central longitudinal axis 68. The locking device 56 and the locking portion 58 are configured such that the locking portion 58 can be secured in the locking device 56 only along a movement path 72 originating from the central longitudinal axis 68.

[0043] In order to fix the locking section 58 in the locking device 56, both the second projection member 30 and the third projection member 44 are removed from the longitudinal configuration, which is particularly in Fig. 4 can be seen, to pivot clockwise so that an arrangement of the cantilever members 30, 44 according to the rest configuration, which is shown in the Figuren 5 , 6 , 7 can be seen. The second cantilever member 30 extends away from the first pivot joint 26, obliquely to the central longitudinal axis 68, so that an acute angle open toward the base housing 66 is enclosed at the first pivot joint by the first cantilever member 16 and the second cantilever member 30.

[0044] As a generally advantageous aspect, in the rest configuration the first pivot joint 26 and the second pivot joint 40 are located on different sides of the central longitudinal axis 68 (cf. Figur 6 ). The boom is thus folded to save space and utilizes the space provided by the off-center arrangement of the support 14.

[0045] The third cantilever member 44 is arranged along the transverse axis 70 between the second pivot joint 40 and the support 14. Due to the rotationally fixed arrangement of the first cantilever member 16 and the lengths 60, 62, 64 of the cantilever members 16, 30, 44, the cantilever members 30, 44 each form a defined angle with one another in plan view, with the first cantilever member 16 and the second cantilever member 30 forming an acute angle, and the second cantilever member 30 and the third cantilever member 44 forming an obtuse angle. Thus, the cantilever members 30, 44 have a compact extension in the lateral direction. This ensures that the handling device 10 does not have any laterally protruding interfering contours when the handling device 10 is in the rest configuration.

[0046] Two tine receptacles 74 are provided on the base housing 66, each accommodating a tine of a fork of an industrial truck. The base housing 66 and the tine receptacles 74 are designed such that the handling device 10 can be driven under by an industrial truck, and a tine can be inserted into each tine receptacle 74. For this purpose, the base housing 66 has a recess 73 provided in the area of the floor, which corresponds at least to the width of the fork of an industrial truck. Commercially available pallets can be placed on the tine receptacles 74, which are also transported when the handling device 10 is transported.

[0047] To provide energy for the handling device 10, a power source 76 is provided in the base housing 66, which is designed as a rechargeable and replaceable tray battery. The power source 76 can be easily inserted into the base housing 66 or removed from the base housing 66. Furthermore, a vacuum pump 78 is housed in the base housing 66. The support 40, the first cantilever member 16, the second cantilever member 30, and the third cantilever member 44 are designed as hollow profiles, with the internal cavities 79 of the hollow profiles forming channels for conveying media and data between the vacuum pump 78 and the connection section 54. The internal pressure guide system 80 thus formed can be used to operate a vacuum-operated lifting and / or gripping device 55.

[0048] As particularly in Fig. 8 As can be seen, two support feet 82 are provided on the base housing 66. The support feet 82 can each be moved along a locking axis 84 into a lower support position and an upper release position. The locking axis 84 runs parallel to the support axis 12. Fig. 8The position shown shows the support feet 82 in the release position, wherein the support feet 82 do not touch the ground. In the release position, the handling device 10 can be moved, for example, by means of an industrial truck. In the lower support position, the handling device 10 stands on the support feet 82, so that the load acting on the handling device 10 is guided into the ground via the support feet 82. The support position ensures that the handling device 10 is stable on the ground. A control 86 is provided in the base housing 66, which is set up such that the support feet 82 move into the lower support position when the locking section 58 is released from the locking device 56 and that the support feet 82 move into the upper release position when the locking section 58 is secured in the locking device 56.
