Description

1 Operator arrangement for a vacuum lifting deviceTECHNICAL FIELD The invention relates to an operator arrangement for a vacuum lifting device. The operatorarrangement comprises a housing being connected to a suction arrangement and to a vacuumsource connection. The operator arrangement comprises a first operating means and a secondoperating means, wherein operating the first operating means lowers the at least one suctionarrangement and operating the second operating means releases a load attached to the suction arrangement.BACKGROUND ART Vacuum lifting devices are well known in the art and are used in many types of business to assistan operator in lifting heavy, cumbersome and/or ungainly items. A vacuum lifting device maycomprise a vacuum source connected to a housing on which suction arrangement is attached.The vacuum source creates a vacuum inside the suction foot when the suction foot is attachedto an item, thereby allowing the item to be lifted and moved. An operator uses operating meanson the housing to raise and lower the suction foot and also to release the load from the suctionfoot. During certain operations of a vacuum lifting device, an operator may have to raise thehousing to a height or orientation that results in an unergonomical position for the operator. lnsuch a position, the operator's hand and arm may have to be placed at a disadvantageous angleand/or position in order to maintain control of the operation ofthe vacuum lifting device. Thiscan lead to both acute and long-term problems such as fatigue, ache and wear damage. There is thus a need for an improved operator arrangement for a vacuum lifting device.SUMMARY OF THE INVENTION One object of the present invention is to provide an inventive operator arrangement for avacuum lifting device where the previously mentioned problems are at least partly avoided. Thisobject is achieved by the features of the characterising portion of claim 1. Variations of the invention are described in the appended dependent claims.

The invention relates to an operator arrangement for a vacuum lifting device. The operator arrangement comprises a housing being connected to suction arrangement and to a vacuum 2source connection. The operator arrangement further comprises a first operating means and asecond operating means, wherein operating the first operating means lowers the suctionarrangement and operating the second operating means releases a load attached to the suctionarrangement. The operator arrangement further comprises an operator handle rotatablyattached to the housing wherein the first and second operating means are attached to theoperator handle. The operator handle can be rotated relative to the housing. One advantagewith an operator arrangement according to the above is that it allows for better ergonomicaluse of the operator arrangement. When using an operator arrangement for a vacuum liftingdevice in situations described above, an operator is given the possibility to rotate the operatorhandle while still maintaining control over the operating means to control the operation of thevacuum lifting device as the operating means are attached to the operator handle. For instance,if the normal hand position is having the palm of the hand facing essentially towards the bodyof the operator, sometimes it is more ergonomical to have a hand position that is rotated suchthat the palm is facing essentially downwards, upwards or away from the body or to a positionthere between. The operator arrangement thus improves the working conditions of users of a vacuum lifting device equipped with this operator arrangement.

The operator handle may be rotatable 360° around its attachment axis. ln order for a user tohave complete rotational freedom, the operator handle may be attached to the housing suchthat it can rotate freely around its attachment axis. The operator handle can rotate both clockwise and counter clockwise relative to its attachment axis.

The first and second operating means may be connected to the housing by a rotatableconnection. One advantage with this feature is that the first and second operating means can rotate with the operator handle while still maintaining complete functionality.

The operator handle may comprise a locking arrangement comprising a locking means arrangedto interact with at least one locking pin. This allows the operator handle to be rotated todetermined fixed positions around its attachment axis. This can assist the user in certainoperations when the user returns to the same position often or when moving between two positions in which one fixed position of the operator handle is preferred for both positions.

The locking means may be arranged to be placed in an open position. This allows the operator handle to be freely rotatable around its attachment axis. When a user moves between many 3different positions or wants to experience freedom of movement, the operator handle can be made to rotate freely by placing the locking means in an open position.

The operator arrangement may comprise a valve arrangement comprising a valve housing, afirst valve plug and a second valve plug connected to the same actuating means, the actuatingmeans being connected to the first and second operating means. The operator arrangementmay comprise a valve arrangement that simplifies the operation of the vacuum |ifting device.By having a valve housing in which both a first and second valve plug are placed and both areconnected to the same actuating means, it is possible to connect both the first and secondoperating means to the one actuating means. This makes operation of the vacuum |ifting device easier and the operator arrangement can be made more compact.

The first valve plug and the second valve plug may be in a closed position when not actuated.Thereafter operating the first operating means may move the first valve plug to an open positionand operating the second operating means may move the second valve plug to an open position.The normal position of the first and second valve plug is in a closed position. ln this positionthere is no outlet of air from the operator arrangement, thereby maintaining the vacuum in thesuction arrangement and keeping the upward directional bias of the suction arrangement asknown in the art. Operating the first operating means moves the first valve plug to an openposition thereby releasing air from the operator arrangement such that the suctionarrangement moves downwards as known in the art. Further operating the second operatingmeans moves the second valve plug to an open position thereby removing the vacuum from the SUCÜOH affafigemefït.

Operating the first operating means may move the first valve plug and the second valve plug,where the first valve plug moves to an open position, thereby lowering the suctionarrangement, and the second valve plug remains in a closed position. As the first and secondvalve plugs are attached to the same actuating means, operating the first operating meansmoves both the first and the second valve plug. The first and second valve plugs are so arrangedthat when operating the first operating means, the first valve plug moves to an open positionwhile the second valve plug moves a distance that maintains the closed position of the secondvalve plug. This ensures that operating the first operating means cannot lead to that the vacuum in the suction arrangement is lost and a load is accidentally released. 4Operating the second Operating means may further move the second valve plug to an openposition. ln order to securely release a load from the suction arrangement, the second operatingmeans needs to the operated. This moves the second valve plug a further distance such that it reaches an open position and the vacuum in the suction arrangement is lost.

The first and second operating means may be operating levers, rotating around the same centreof rotation. As one alternative, the first and second operating means are levers. They areattached to the operator handle on a common pivot centre or centre of rotation and asdescribed above may be connected to the housing by a rotatable connection. This allows for anoperator to operate both operating means with the use of his/her fingers as compared totoday's solutions often requiring use of both fingers and the palm of his/her hand. Other typesof mechanical operating means using a common pivot centre or centre of rotation are of course also conceivable.

The first and second operating means may control electromechanical actuators. As anotheralternative, push buttons or similar placed on the operator handle can be used to controlelectromechanical actuators placed inside the operator handle. The actuators are in this caseconnected to the housing by a rotatable connection and the function is as described above.Normally, two push buttons are used, but one push button may also be used and can be programmed to perform the operations of both the first and second operating means.

The first and second valve plugs may be biased to return to their closed position. Upon releaseof the first and second operating means, the first and second valve plugs preferably return totheir closed position. This can be done by for instance spring loading in the case of mechanical operating means or by programming in case of electromechanical actuators.

The operator handle may comprise a remote control radio chip. The chip allows for operationof functions of the vacuum lifting device normally controlled by a control device placed on thevacuum lifting device. Examples of such functions can be turning the vacuum source on or off or changing the work height of the vacuum lifting device.

The suction foot may be rotatably arranged in relation to the housing. The vacuum sourceconnection may be rotatably arranged in relation to the housing. Both of these features allow for a greater freedom of operation for the user.

DETAILED DESCRIPTION Figure 1 schematically shows a perspective view of an operator arrangement 1 according to theinvention. The operator arrangement 1 comprises a housing 2 being connected to one suctionarrangement 3 and to a vacuum source connection 5, in the figure indicated by the connectingtubes 4 attached to a vacuum source connection 5. The vacuum source connection 5 connectsthe operator arrangement 1 to a vacuum source such as a vacuum pump. ln the example shownin figure 1, the suction arrangement 3 comprises one suction foot. lt is possible for the suction arrangement 3 to have more than one suction foot, for instance two, three or four suction feet. 6Even more suction feet are also possible. The connection to the vacuum source can be oneconnecting tube 4 or more than two connecting tubes 4 depending on the application and theamount of air that needs to pass through the connecting tubes 4. The suction arrangement 3 and the vacuum source connection 5 are rotatably connected to the housing 2.

The operator arrangement 1 further comprises a first operating means 6 and a second operatingmeans 7, wherein operating the first operating means 6 lowers the suction arrangement 3 (aswell as the entire operator arrangement 1) and operating the second operating means 7releases a load attached to the suction arrangement 3. The operator arrangement 1 furthercomprises an operator handle 8 rotatably attached to the housing 2 wherein the first operatingmeans 6 and second operating means 7 are attached to the operator handle 8. The operatorhandle 8 can be rotated around its attachment axis 21, at least 90° clockwise or counter-clockwise, specifically 180° clockwise or counter-clockwise and more specifically 360° clockwiseor counter-clockwise. The housing 2 further comprises a leak valve 9 which is used to regulatean amount of leakage through the housing 2. The amount of leakage determines how fast thesuction foot (and the rest of the operator arrangement) rises when the first operating means 6 are not operated.

The operator arrangement 1 has a longitudinal extension X, a lateral extension Y and a vertical extension Z as illustrated in figure 1.

The operator handle 8 of figure 1 comprises a remote control radio chip 40 inside the operatorhandle 8. The remote control radio chip 40 allows for operation of functions of a vacuum liftingdevice normally controlled by a control device placed on the vacuum lifting device. Examples ofsuch functions can be turning the vacuum source on or off or changing the work height of thevacuum lifting device. Operations are performed by one or more push buttons 41 connected to the remote control radio chip 40.

Figure 2 schematically shows a cross section of an operator arrangement 1 according to theinvention. ln figure 2, a valve housing 10 can be seen as well as a first valve plug 11 and a secondvalve plug 12. The first valve plug 11 and the second valve plug 12 are arranged on or connectedto the same actuating means 13. The actuating means 13 can be a valve rod or valve pistonactuated by the first and second operating means 7, 8. The actuating means 13 is in turn journaled in bearings or bushings in the valve housing 10 and is arranged to move in a 7longitudinal direction X. The actuating means 13 extend through the valve housing 10 towardsthe operator handle 8. One end of the actuating means 13 connect to the second operatingmeans 7 by a rotatable connection 15 comprising a first connection part 16 connected to theactuating means 13 and a second connection part 17 connected to the first operating means 6and second operating means 7. The second connection part 17 can rotate freely relative to thefirst connection part 16 and that allows the operator handle 8 and the first operating means 6and second operating means 7 to rotate relative the housing 2. lt is also possible for the firstconnection part 16 to rotate freely relative to the second connection part 17. Alternatively, the actuating means 13 rotates with the rotation of the operator handle 8.

The actuating means 13 comprises first, second and third pushers 13a, 13b, 13c with the firstpusher 13a arranged to push on the first valve plug 11 when the first and second operatingmeans 7, 8 are actuated and the third pusher 13c arranged to push on the second valve plug 12when the second operating means 8 is actuated. The second pusher 13b is arranged to push onthe second valve plug 12 when the actuating means 13 is returned to its starting position whenthe first and second operating means 7, 8 are released. This is further described below. A spring14 is biased to return the actuating means 13 to its starting position. The spring 14 or other kinds of return means can be positioned on different parts ofthe actuating means 13.

The valve housing 10 has a first valve housing opening 18 open towards the vacuum sourceconnection 5 in order to allow air to flow through the valve housing 10 when then first operatingmeans 6 and second operating means 7 are actuated. The valve housing 10 further comprises asecond valve housing opening 19 normally closed by the first valve plug 11. The housing 2further comprises a housing opening 20 through which the first valve plug 11 can move in orderto allow air in from the surrounding through the second valve housing opening 19 when the first operating means 6 is actuated.

The first valve plug 11 has a larger cross-sectional area than the second valve plug 12 in orderto balance the forces exerted on respective valve plug 11, 12 when operated. The cross-sectional area of the valve housing 10 is adapted accordingly. The transition between the twocross-sections are merely illustrative. The first valve plug 11 further comprises a first valve plugpart 11a which can be operated separately from the remainder ofthe first valve plug 11 by that it is directly attached to the actuating means 13 which runs through the first valve plug 11. 8The operator handle 8 is rotatably attached to the housing 2 and an attachment axis 21 of theoperator handle 8 is parallel with and may run through, and in the direction of, the actuatingmeans 13. An attachment interface 22 between the housing 2 and the operator handle 8 is inthe example of figure 2 essentially perpendicular to the actuating means 13. lt is possible tohave an attachment axis 21 that is at an angle relative to the extension of the actuating means13 by having a tilted attachment interface 22 of the operator handle 8 relative the housing 2 and thereby the actuating means 13.

The first operating means 6 and the second operating means 7 are, in the embodiment of figure2, operating levers. The first operating lever 6 is longer than the second operating lever 7 inorder to clearly distinguish for an operator which operating lever 6, 7 performs which operation.The first operating lever 6 and second operating lever 7 are attached to the operator handle 8at a common centre of rotation 23. As both the first operating lever 6 and second operatinglever 7 are connected to the same actuating means 13, having the first operating lever 6 andsecond operating lever 7 attached to the operator handle 8 at a common centre of rotation 23allows for a compact build of the operator arrangement 1. lt is conceivable to have the firstoperating lever 6 and second operating lever 7 attached to the operator handle 8 with different centres of rotation as long as both are connected to the same actuating means 13.

Figure 3 schematically shows a perspective view of the housing 2 with parts of the housing 2removed in order to illustrate parts ofthe flow of air through the operator arrangement 1. Thesuction foot of the suction arrangement 3 comprises an open channel (not shown) into thehousing 2 and is connected pivotably and rotatably to the housing 2 by means of the suctionarrangement 3. The suction arrangement 3 can be rotated 360° around its vertical axis whichlies essentially in the vertical direction Z. The suction arrangement 3 is normally in a horizontalposition but can be rotated approximately 90° around a lateral pivoting axis 38 to a verticalposition (not shown) by means of a suction arrangement opening 39 in the housing 2. The openchannel of the suction arrangement 3 continues into the hollow suction arrangementconnection 24 which in turn is connected to the valve housing 10 through a first passage 25inside the housing 2. The first passage 25 connects to a third valve housing opening 26 which the second valve plug 12 covers as long as the second operating means 7 are not actuated. 9Figure 4 schematically shows a cross section of an operator arrangement 1 according to theinvention in which the first operating means 6 and second operating means 7 are not actuated.ln this first state, the first valve plug 11 and second valve plug 12 of the valve housing 10 are intheir respective closed positions and no air can pass through the valve housing 10 from thesuction arrangement 3 or from the surroundings through the valve housing 10 and the vacuumsource connection 5. There is a s|ight gap between the first pusher 13a and the first valve plug 11.

Figure 5 schematically shows a cross section of an operator arrangement 1 according to theinvention in which the first operating means 6 is initially actuated. ln figure 5, the first operatingmeans 6 is initially or partly actuated. ln figure 5, the first operating means 6 has been moved asmall distance leading to that the first valve plug part 11a has moved away from the first valveplug 11. ln this second state, first valve plug openings 11b allow air to enter the valve housing10 from the outside in order to increase the pressure in the valve housing 10 and to simplify theactuation of the first valve plug 11 which can be difficult to move if the pressure inside the valve housing is low.

Figure 6 schematically shows a cross section of an operator arrangement 1 according to theinvention in which the first operating means 6 is fully actuated. As can be seen from figure 6,the entire actuating means 13 and thereby the first valve plug 11 has moved a first distance L1by that the first pusher 13a has acted against the first valve plug 11. ln this third state, the firstvalve plug 11 has moved, opening the valve housing 10 towards the surroundings. ln this state,air flows from the surroundings through the second valve housing opening 19, the first valvehousing opening 18 and the vacuum source connection 5, thereby reducing the lift generatedby the vacuum source. This leads to that the normally biased upwards movement of the suctionarrangement 3 (and entire operator arrangement) is changed into a neutral position or downwards movement ofthe suction arrangement 3.

The second valve plug 12 has not moved and still covers the first valve housing opening 18 suchthat no air can flow through the third valve housing opening 26 to the first passage 25 to thesuction arrangement 3. The third pusher 13c has moved with the actuating means 13 and abuts the second valve plug 12. A vacuum generated in the suction arrangement 3 is thereby preserved such that a load attached to the suction arrangement 3 will remain attached during actuation ofthe first operating means 6.

Figure 7 schematically shows a cross section of an operator arrangement 1 according to theinvention in which the second operating means 7 is actuated. ln figure 7, the second operatingmeans 7 is fully actuated. The actuating means 13 has moved further and thereby the first valveplug 11 has moved a second distance L2. The second valve plug 12 has moved such that apassage from outside the operator arrangement 1 through a fourth valve housing opening 27to the suction arrangement 3 via the third valve housing opening 26 and the first passage 25 iscreated as indicated by the arrows. The vacuum present in the suction arrangement 3 is therebyreleased such that a load attached to the suction arrangement 3 will be released upon actuation ofthe second operating means 7.

The first valve plug 11 and the second valve plug 12 are preferably biased to return to theirclosed position once the operator stops actuation of the first operating means 6 and second operating means 7. This is illustrated in the figures by a spring 14.

Figure 8 schematically shows a perspective view of the operator arrangement 1 according tothe invention with parts ofthe operator arrangement 1 removed. ln figure 7, the valve housing10 is shown as well as the leak valve 9. The rotation of the leak valve 9 is limited by a stop (not shown), ensuring that the leak valve 9 can only be turned in one direction.

As an alternative to leak valve 9, a damper (not shown) can be mounted in the same position asthe leak valve 9. The damper is normally closed and connected to the actuating means 13 bymeans ofa guide (not shown) arranged to open and close the damper when the actuating means13 moves. When the first operating means 6 is actuated, the guide moves with the actuatingmeans 13, opening the damper. This results in an increase ofair released from the valve housing,making the entire operator arrangement easier to handle. The more the first and secondoperating means 6, 7 are actuated, the more the damper is opened. Conversely, when the firstand second operating means 6, 7 stops being actuated, the spring 14 returns the actuatingmeans 13 to its initial position, closing the damper. This results in that vacuum is more quicklycreated in the operator arrangement, leading to that it takes shorter time before an item attached to the operator arrangement can be lifted. 11The operator arrangement 1 comprises a locking arrangement 28. The locking arrangement 28comprises a locking ring 29 attached to one end of the valve housing 10. The locking ring 29comprises a number of locking pins 30 arranged at predetermined intervals, for instance every45°, every 30° or every 15°. The locking arrangement 28 further comprises a locking means 31comprising a locking slot 32 arranged to engage with a locking pin 30 of the locking ring 29. Thelocking means 31 rotates with the operator handle 8 and is attached to the operator handle 8and rotatably attached to the actuating means 13. When the locking slot 32 is engaged with alocking pin 30, the locking means 31 is in a locked position. The locking means 31 can be movedaway from the locking ring 29 in an essentially longitudinal direction towards the first operatingmeans 6 and second operating means 7 such that the locking means 31 no longer engage withthe locking pins 30. This allows the operator handle 8 to rotate freely relative to the housing 2.When the locking slot 32 of the locking means 31 is not engaged with one ofthe locking pins 30,the locking means 31 is in an open position. The locking means can be locked in its open position by means of any suitable kind of mechanical arrangement, e.g. a bayonet mount.

Figure 9 schematically shows a cross section of the operator arrangement 1 in a partiallyexploded view in order to illustrate the movement of the first operating means 6 and the secondoperating means 7 and thereby the actuating means 13. The first operating means 6 and secondoperating means 7 are arranged such that the first operating means 6 is divided into two partsat an upper end 33 attaching the first operating means 6 to the operator handle 8. The secondoperating means 7 is placed between the two parts of the first operating means 6. An operatingmeans connection 34 runs in a lateral direction Y from a first channel 35 inside the operatorhandle 8, through one of the parts of the first operating means 6, through a second channel 36in the second operating means 7, through the second of the parts ofthe first operating means6 and ending in a third channel (not shown) inside the operator handle 8 on the opposite sideof the first channel 35. The operating means connection 34 is placed at a distance from thecommon centre of rotation 23 in order to provide for a moment arm allowing rotation around the common centre of rotation 23.

The first channel 35 and the third channel are of the same length and are located in the sameplace on each respective lateral side of the operator handle 8. The first operating means 6 isarranged to press on the second operating means 7 when actuated by means of the operating means connection 34. The channels 35, 36 and operating means connection 34 are arranged 12such that in the first state, the operating means connection 34 is arranged at a lower end 37 ofthe second channel 36. This results in that when operating the first operating means 6 to thesecond state, the operating means connection 34 moves both the first operating means 6 andsecond operating means 7 and thereby the actuating means 13 a first distance L1 correspondingto the length of the first channel 35. The operating means connection 34 is still arranged atlower end 37 of the second channel 36, thereby allowing the second operating means 7 to bemoved a second distance corresponding to the length of the second channel when the firstoperating means 6 have been moved a first distance. This operation of the first and second operating means is also illustrated in figures 4-6.

The operator handle 8 is attached to the housing 2 by means ofa first attachment plate 42 whichis attached to the operator handle 8 for instance by welding or screwing to a handle core 8a.The first attachment plate 42 is attached to a second attachment plate 43 which is turn isattached to the locking means 31. Upon rotation of the operator handle 8, the rotation istransferred through the attachment interface 22 by means ofthis connection as well as through the rotatable connection 15. lt is to be understood that the functions ofthe operator arrangement can be achieved also whenthe first and second operating means 7, 8 are only partially actuated. Full actuation may not berequired. For instance the lift of the operator arrangement can be regulated by actuating thefirst operating means 7 differently to achieve a slower ascent, a neutral position or different rates of descent.

Reference signs mentioned in the claims should not be seen as limiting the extent ofthe matter protected by the claims, and their sole function is to make claims easier to understand.

As will be realised, the invention is capable of modification in various obvious respects, allwithout departing from the scope of the appended claims. Accordingly, the drawings and the description thereto are to be regarded as illustrative in nature, and not restrictive. 13 References BLOOOQCDLFI-ÄUUIUIJ IJIJ IJI\J IJUU IJ-ß IJU'l IJCD IJ\| IJ00 IJLO I\JO I\JIJ I\JI\J I\JUU I\J-ß I\JU'l I\JCD I\J\| I\J00 I\JLO UUO UUIJ UUI\J UUUU UU-ß UUU'l UUCD UU\| UU00 UULO .Operator arrangement .
