Description

Handling device and mast for it

The invention relates to a mast and a manipulation apparatus with the mast according to the invention, as described in the preambles of claims 1 and 14.

From DE 200 21 010 U1 a mast is known for a handling device having a hollow profile shaped body and guides that have a longitudinal direction of the mast body and a lifting carriage provided with wheels of guide. The mast body is composed of a supporting and guiding body, which are joined together by welding, rivets and the like. The guide body has first and second guides arranged symmetrically around a central plane as well as a third guide arranged between them. The first and the second guide configure guide slides that have a parallel and perpendicular path with respect to the central plane and the third guide, guide slides that have a parallel and parallel path with respect to the central plane, being applied the guide wheels of the lift carriage so that they can roll on the guide slides that configure the tread surfaces. The arrangement of three guides leads to a complex cross-section of the mast and the support of the guide rollers in the lifting carriage requires more installation space.

From DE 198 04 854 C2 a mast is known for a handling apparatus, particularly a stacker rack, comprising a hollow profile shaped mast body, a lifting device and guides having a longitudinal direction travel of the mast body, the lifting device presenting a lifting carriage that can be moved along the guides. The guides have rolling surfaces that have a path in planes parallel to each other and perpendicular to a central plane, in which the tread wheels are applied so that they can roll. A side guide of the lifting carriage is not provided.

From EP 1 211 215 B1, a handling apparatus, particularly a stacker rack, is known, which has a translation mechanism and a mast fixed thereon, the mast and the transfer mechanism being detachably connected to each other. through fixing screws.

WO 02/100759 A1 discloses a mast for a handling apparatus having a hollow profile shaped body and guides that have a longitudinal direction of the mast body and a lifting carriage provided with guide wheels. The mast body is composed of two semi-covers, each of the half-roofs being configured both the support body and the guide body and which are joined together by indirect welding. The mast body or the semi-decks are arranged symmetrically around a central plane and have, facing each other, a first guide and a second guide as well as a third guide in the part of the wall that extends between them.

Finally, JP 2007-238197 A shows a handling apparatus comprising a stationary frame frame, a mast fixed therein with a hollow profile shaped body, a lifting device and guides having a path in longitudinal direction of the mast body. The neck body is produced as a single piece. The lifting device has a traction means drive and a lifting carriage that can be adjusted by means of it along the guides. The traction means drive comprises reversing pulleys housed in the mast on the head side and on the foot side, a drive wheel disposed separately from the mast body and coupled to a lifting drive as well as a driven traction means. around drive wheels and reversing pulleys. The lifting drive with the drive wheel is fixed by screws to the frame frame of the handling device.

The present invention aims to create a mast that is characterized by its simple constructive form and by which the constructive configuration of a lifting device can be simplified. This mast must be particularly suitable for use in a handling device.

The object of the invention is solved by the features of claim 1.

It is advantageous that the lateral guide of the lifting carriage is made in a first and second direction in space through two guides that have a longitudinal direction of the mast body. Each guide configures at least two guide slides that include an angle to each other, on which tread surfaces are applied tread wheels of the lift carriage. For this reason, a structured guide is created in a simple way, along which the lifting carriage can be graduated with high guidance accuracy in the vertical direction. In addition, a third guide can be dispensed with in the guidance system against the guiding principles known in the state of the art, whereby a mast weight saving is achieved and a handling device can be moved very dynamically equipped with the mast according to the invention.

The mast body is structured in several pieces, in such a way that prefabricated support and guide bodies of different configuration or size can be combined in a discretionary way adjusted to different applications. Thanks to the standardization of the supporting and guiding bodies, a

mast with reduced production costs.

It is also advantageous that a first branch of the traction means is guided inside the mast body in the form of a hollow profile. Thanks to this measure, a separation between a vertical reference axis in the center of the mast area and an axis in the load center can be reduced. Thanks to this, a space-saving arrangement of the lifting device is possible as well as a housing frame of the lifting device. This is particularly advantageous when the mast is used with the lifting device in a lift vehicle that can be moved on a racking path between storage shelves placed on both sides thereof, since the degree of approach in the direction of the track (x direction). Furthermore, thanks to the guide of the drive of traction means with its first branch inside the mast and its second branch outside the mast and with the interaction of the pre-tension in the tension medium, the state of static load on the mast resulting from the load weight that acts eccentrically on the body of the mast. Thanks to the lower load on the mast a thin-walled construction of the mast body and also of the guides with a sufficiently high rigidity is possible.

The configuration according to claim 2 is also advantageous, since the mast together with the drive means drive forms an independent construction unit, which can be transported with much space saving separated from other construction units, such as a translation mechanism, housing framework

or a load accommodation device. The assembly of the individual construction units, such as, for example, the assembly of the mast in the movement mechanism of a handling apparatus can be carried out at the customer's place without major complexities. An essential advantage of the arrangement of the traction means drive in the mast also consists in that it is not necessary to release the pre-tension in the traction means when the mast and the translation mechanism are transported separately from each other for the purpose of transport. The pre-tension is adjusted on the factory side and on the client side the construction units must be mounted exclusively on construction interfaces (mast / translation mechanism or tension device / lifting carriage) with each other, however , a pre-tension in the traction means must not be adjusted. Adjusting the pre-tension in the traction means requires maximum precision, requires corresponding measuring devices (s) and skilled labor. Only when the pre-tension has been adjusted exactly is a reliable operation of the lifting device possible. It is known from the state of the art that the pre-tension in the traction means, particularly of a belt, is adjusted by measuring the proper vibration frequency. Due to the fact that pre-tension in the traction means is already adjusted on the factory side, assembly errors at the customer's place that occur due to less instructed personnel can be avoided.

An advantageous configuration of the invention is also described in claim 3.

If the lifting drive is mounted separately from the mast on a translation mechanism of the handling apparatus, as described in claim 4, only a drive shaft connected to one of the reversing pulleys is provided, which can be join the lifting drive through a coupling drive. Thanks to this, despite this, the advantage is preserved that the pre-tension in the traction means does not have to be released when the mast and the transfer mechanism are transported separately from each other and in addition the handling of the mast during assembly in the translation mechanism.

An advantageous configuration of the guide slides is described in claim 5.

It is also advantageous that the first guide and the second guide are configured in the guide body respectively, protruding on the one hand in the separation plane, as described in claim 6.

According to the embodiment according to Figure 7, the supporting body is configured in several pieces and its profile walls and the supporting profile are connected to each other by means of joining elements or assembly joints. In a preferred embodiment, the connecting elements are formed by threaded joints separated in the longitudinal direction of the mast body. Thanks to the possibility of disassembly, for example, of a profile wall, electrical or mechanical construction components can be integrated very easily into the mast body as a hollow profile. On the other hand, it is therefore created the possibility that individual profile walls or the supporting profile can be replaced with damage to the mast. Therefore, it is no longer necessary to completely replace the mast, but only individual segments.

According to the embodiment according to claim 8, a reliable drive function of the drive means drive on the carriage is achieved and a reliable guide function of the carriage along the guides in the mast.

The configuration according to claim 9 is also advantageous, since thanks to the recesses the mast's own weight is reduced and the recesses can be used at the same time as an auxiliary means of climbing, particularly of stairs. Therefore, an additional auxiliary lifting means can be dispensed with, which is fixed on the side of the mast opposite to the lifting carriage, and thereby reduce the total weight of a handling device, avoid costs and make the dynamic operation of the handling device

It is also advantageous to refine the invention according to claim 10, since by means of the adjustment device the housing frame of the carriage can be adjusted exactly with respect to a particularly horizontal reference plane without making it difficult to do so. equipment works

According to the configuration according to claim 11, a locking device is additionally provided, by means of which the adjusted relative location of the housing frame can be fixed.

The modularity of the mast is ensured by the configuration according to claim 12. Between the tension device and the mounting element a mounting plane (mounting interface) is configured and the lifting carriage can be separated together with the housing frame through the fixing device through few maneuvers of the drive of traction means. The fixing device can be formed by quick closing elements, screws and the like.

The configuration according to claim 13 is also advantageous, since the housing frame has mounting interfaces that can be adapted to different cargo housing devices for storing and extracting merchandise in bales on or from a shelf of the shelving. In this way it is common for cargo housing devices to be differentiated according to weight classes, size classes, functional classes and the like. Such load-bearing devices have a mounting platform and mounting points such as openings, positioning means and / or blocking means and the like. According to the invention, a separation between the mounting interfaces with respect to a separation between the mounting points can be adjusted continuously and the mounting of a load-bearing device directly. According to this, the mounting interfaces configure an assembly drawing. Additional machining steps can be dispensed with, such as, for example, the application of perforations and the like for mounting the load bearing device on the housing frame.

However, the object of the invention is also solved thanks to the features of claim 14. The handling apparatus is equipped with the mast produced with a lightweight construction form and having a high rigidity and, therefore, the apparatus for handling can be operated with high dynamics and the production costs of the handling apparatus can be significantly reduced.

According to the configuration according to claim 15, both the mast and the translation unit form respectively separate construction units, which are joined together in a mounting plane (mounting interface) through removable joining elements. Therefore, the modularity of the handling device is guaranteed.

Finally, the configuration according to claim 16 is also advantageous, since the housing frame with its supporting arms can be moved down laterally to the side of the translation mechanism and, thus, the degree of approach in the Y direction can be further optimized and You can increase the amount of placement points in the storage rack in the vertical direction.

For the best understanding of the invention, it is explained in more detail by the following figures.

By way of introduction it is pointed out that in the embodiments described in different ways, the same parts are provided with the same references or the same designations of constructive parts, being able to transfer the disclosures contained throughout the description in a reasoned manner to the equal parts with the same references or the same denominations of constructive pieces. Also the location indications selected in the description such as, for example, up, down, laterally etc. they refer to the figure directly described as well as represented and must be transferred in case of a change of location in a reasoned way to the new location.

Figures 1 to 10 described together show a handling apparatus 1 according to the invention. The manipulation apparatus 1 is formed, according to this embodiment, by a stacker rack. The rack stacker has a mast 2 arranged perpendicularly, a lifting device 3, a lower translation mechanism 4 fixed on the foot of the mast, an upper translation mechanism 5 fixed on the head of the mast and a distribution cabinet not shown with more detail The lower translation mechanism 4 is guided in a lower translation rail 6 and the upper translation mechanism 5, in an upper guide rail 7. The lower translation rail 6 is configured as a support in I. The upper belt configures, on its upper side directed towards the translation mechanism 4, an upper guide slide and on its lower side opposite the translation mechanism 4, a slide of lower guide The lower belt is fixed to the building. The perpendicular bar that joins the upper and lower belt sets on its opposite sides to each other guide slides. The upper guide rail 7 is configured, for example, as an angled profile. The perpendicular profile bar configures on its opposite sides each other guide slides. The horizontal profile bar is attached to the building or to a storage shelf not shown.

The lower translation mechanism 4 comprises a translation frame 9, in which tread wheels 10a, 10b are housed so that they can roll on both sides of the mast 2 in the direction of movement 8 (x direction) one after the other on the upper guide slide of the translation rail 6 and which can rotate around horizontal axes. Additionally, pairs of counter rollers 11a, 11b are housed that are next to each other and that can rotate around horizontal axes, which are applied so that they can roll in the translation frame 9 on both sides of the mast 2 in the direction of movement 8 one after the other on the lower guide slide of the translation rail 6. The lateral guide of the lower translation mechanism 4 is achieved at one end of the translation frame 9 thanks to guide rollers 12 applied so that they can roll on the bar perpendicular to the translation rail 6 and which can rotate around perpendicular axes, which are in pairs next to each other and at the other end of the translation frame 9, thanks to drive rollers 13 that are applied so that they can roll in the perpendicular bar of the translation rail 6 and which can rotate around perpendicular axes, arranged in pairs side by side.

The transmission of the force of the lower translation mechanism 4 to the translation rail 6 is carried out through the driven drive rollers 13, which act with force closure. The drive rollers 13 are respectively coupled to a translation drive 14. The translation drives 14 are preferably formed by an electric motor, particularly an asynchronous motor, synchronous motor and the like.

The upper translation mechanism 5 comprises an upper translation frame 15, in which two pairs of guide rollers 16a, 16b are housed that can rotate around perpendicular axes, which are applied so that they can roll on both sides of the mast 2 in the direction of movement 8 one after the other in the vertical guide slides of the guide rail 7.

Figures 2 and 3 show the fixing of the mast 2 to the lower translation mechanism 4 in different views. The mast 2 to be described still in more detail is made in a lightweight construction form and configures a mast body in the form of a hollow profile, which has with respect to the direction of movement 8 a supporting profile 21a, 21b anterior and posterior and walls of profile 22a, 21b that join them. The supporting profiles 21a, 21b and the profile walls 22a, 21b are joined through joining elements in a detachable manner or through permanently assembled joints until they give a profile with a closed cross-section (box-shaped profile), as described in more detail in Figures 4 to 6.

As can be seen in the figures, the mast body is fixed with flexural strength through mounting plates 23a, 23b in the lower translation mechanism 4. The mounting plates 23a, 23b are supported with a mounting surface 24 directed towards the translation mechanism 4 on a mounting surface 25 configured by the translation mechanism 4 and directed towards the mast 2 as well as detachably connected respectively through of several connecting elements 26 with the translation frame 5. The mounting surface 25 forms a mounting plane (mounting interface) between the mast 2 and the translation mechanism 4. The connecting elements 26, according to this embodiment, are formed, respectively, by screws. The screws between the translation mechanism 4 and the mounting plate 23a, 23b are aligned perpendicularly on the mounting surface 24. A reinforcing element 27 between the screw head and the translation frame 9 of the translation mechanism 4 allows a travel optimum of the flow of force between the constructive units to join.

Each support plate 23a, 23b has a base part 28 adjacent to the translation mechanism 4 and a head part connected therewith. The head part comprises mounting tabs 29 projecting in the base part 28, separated from each other by a notch. The base part 28 configures the mounting surface 24 and side walls 30 which have an inclined path with respect to each other and which widen with increasing separation from the mounting surface 24. The notch provided between the mounting tabs 29 configures surfaces of limitation 31 that have an inclined path and that widen with increasing separation of the base part 28.

As can be seen in Figures 2 and 3, the support plate 23a, 23b has a thickness of material 33 that narrows starting from the mounting surface 24 in the direction of a limitation surface 32 that faces it with increasing separation.

The mounting plates 23a, 23b and the supporting profiles 21a, 21b are connected to each other respectively through several connecting elements 34 detachably or through permanently assembling joints. The connecting elements 34, according to this embodiment, are formed by screws separated in the longitudinal direction of the mast 2, such that the mounting plates 23a, 23b are detachably connected with the mast 2. The screws between the mast 2 and The mounting plate 23a, 23b are particularly aligned on the plane of the plate.

In the same way, however, it is also possible that the mounting plates 23a, 23b and the supporting profiles 21a, 21b are permanently joined together by means of assembly joints, particularly a welding bead, indirect welding or adhesion or by pressure bonding. (riveted)

By means of the constructive configuration of the mounting plates 23a, 23b and the union of the mast 2 with the translation mechanism 4 through the mounting plates 23a, 23b an optimized path of the flow of force between the mast 2 and the mechanism is achieved of translation 4 and it is ensured that all the connecting elements 34 or assembly joints arranged between the mounting plate 23a, 23b and the mast 2 are loaded approximately uniformly.

In Figures 1 and 4 described together a first embodiment of the mast 2 is shown which forms a hollow profile shaped body in the form of a light construction.

The mast body has a support body 35 and a guide body 37 that are connected to each other in a separation plane 48 that is located between them in the longitudinal direction of the mast 2 through joining elements 36 detachably or permanently through assembly joints.

The support body 35 is composed of the support profile 21b and the profile walls 22a, 22b. The profile walls 22a, 22b are respectively designed approximately C-shaped and at their free ends are provided with connecting flanges 40 projecting at a right angle in a profile wall part 39. The profile wall part 39 Between the connecting flanges 40, a recess 41 can be present which has a longitudinal direction of the profile wall 22a, 22b, whereby a stiffening of the profile walls 22a, 22b is achieved.

The supporting profile 21b is designed in a C-shape and at its free ends is provided with guide flanges 43 projecting in a profile wall part 42. The profile wall part 42, in turn, is provided with at least a recess 44 having a longitudinal direction of the support body 35, which serves to stiffen the support profile 21b. The profile wall portion 42 forms a bearing surface between the guide flanges 43 and the recess 44, against which the profile walls 22a, 22b are supported with their connecting flanges 40.

The supporting profile 21b and the profile walls 22a, 22b are connected to each other, respectively, through several joining elements 38 detachably or permanently through assembly joints. The connecting elements 38, according to this embodiment, are formed by screws separated in the longitudinal direction of the mast 2, such that the support profile 21b is detachably connected with the profile walls 22a, 22b.

However, in the same way it is also possible that the supporting profile 21b and the profile walls 22a, 22b are permanently connected to each other through assembly joints, particularly a welding bead, indirect welding or adhesion or by joining pressure (riveted).

The guides 46a, 46b are separated from each other at least the width 52 of the drive means 45. An advantageous concept of the guide of the lifting carriage is achieved when a central separation 53 between the guides 46a, 46b is greater than a maximum width. 53 of the cross section of the mast.

The support body 35 and the guide body 37 are joined in the separation plane 48 in the area of the connecting flanges 40, 51 through joining elements 36 until a mast body with dimensional stability is given, particularly with stiffness to flexion and torsion. As it has been drawn with broken lines in Figure 4, a stiffening element can be additionally arranged between the profile wall part 39 and the connecting flange 40 adjacent to the support profile 21a and / or 21b, through the connecting elements 36 and / or 38, with the support and guide body 35 and / or 37. The joining elements 36, according to this embodiment, are formed by screws separated in the longitudinal direction of the mast 2, such that the body holder 35 and guide body 37 are detachably connected to each other.

However, in the same way it is also possible that the support body 35 and the guide body 37 are permanently connected to each other through assembly joints, particularly a welding bead, indirect welding or adhesion or by pressure bonding ( riveted).

The guide body 37 is preferably produced as a part from a sheet metal cut by forming, particularly cold forming, such as bending, rolling and the like.

The guides 46a, 46b are designed, respectively, as a closed profile and have, with small cross-sectional dimensions, high dimensional stability, such that a high load weight can be carried on the lifting carriage.

Each guide 46a ", 46b" is additionally provided with a connecting flange 51 having a parallel path with respect to the separation plane 48.

The guide body 37 '' is preferably produced as a part from a sheet metal cut by forming, particularly cold forming, such as bending, rolling and the like.

The support body 35 '' and the guide body 37 '' are joined in the separation plane 48 in the area of the connecting flanges 40, 51 through joining elements 36 until a mast body with dimensional stability is given, particularly with flexural rigidity and torsion. The connecting elements 36, according to this embodiment, are formed by screws separated in the longitudinal direction of the mast 2, such that the support body 35 '' and the guide body 37 '' are detachably connected to each other.

However, in the same way it is also possible that the support body 35 "and the guide body 37" are permanently attached to each other through assembly joints, particularly a welding bead, indirect welding or adhesion or by joining pressure (riveted).

The cross-sections of mast described above show, respectively, a box-shaped configuration of the mast 2, 2 ', 2 "which can be adapted, in a constructively simple manner, to different requirements, such as the acceleration values of the handling apparatus 1, mast length 2, 2 ', 2 ", load weight and the like. The mast 2, 2 ', 2 "is essentially loaded by bending pairs in the direction of movement 8 (x direction), which are caused by the load weight acting eccentrically on a housing frame (Figures 1 and 7) and the mass inertia forces when accelerating and decelerating the handling apparatus 1.

With this background it is possible to optimize very simply by modifying a height 56 (only drawn in Figure 4) of the cross section of the mast, that is, the separation of the support profiles 21a, 21b in the direction of movement 8, the axial area moment for mast flexion 2, 2 ', 2' 'around the gravity axis

x. By changing the width 54 of the cross section of the mast, that is to say, the separation of the profile walls 22a, 22b perpendicular to the direction of movement 8, the moment of axial area for flexion can be optimized very easily of the mast 2, 2 ', 2' 'around the axis of gravity and. Therefore, in spite of the reduced wall thicknesses of the support profiles 21a, 21b and the profile walls 22a, 22b a mast 2, 2 ', 2 "can be created with a high flexural and torsional stiffness as well as a reduced weight, particularly

The wall thicknesses of the supporting profiles 21a, 21b and the profile walls 22a, 22b can be individually adapted to different requirements. Due to the flexural rigidity of the mast 2, 2 ', 2 ", the wall thickness of the support profiles 21a, 21b will be greater than the wall thickness of the profile walls 22a, 22b.

The maximum request for flexion of the mast 2, 2 ', 2 "is in the area of the mast foot, while the solicitation in the area of the head of the mast is lower. From this the requirement that should increase is obtained the moment of resistance of the head of the mast in the direction of the foot of the mast For example, it is possible that the support profiles 21a, 21b are conically shaped in the longitudinal section and that the wall thickness of the profiles is continuously reduced fasteners 21a, 21b starting from the foot of the mast with increasing separation in the direction of the head of the mast On the other hand, the wall thickness of one or both supporting profiles 21a, 21b and / or one or both profile walls 22a, 22b is it can also increase only in the area of the foot of the mast along a part of the length of the mast, for example, they may be provided in the area of the foot of the mast in one or both supporting profiles 21a, 2 1b and / or one or both profile walls 22a, 22b additionally stiffening elements. In other words, with the construction configuration according to the invention of the mast 2, 2 ', 2 "the wall thickness of the supporting profiles 21a, 21b and / or the profile walls 22a, 22b can be adapted locally to the solicitations, particularly bending, twisting or similar moments, without having to change the basic construction of the handling apparatus 1.

On the other hand, the mast 2, 2 ', 2 "for the adaptation to different requirements can be composed of different materials. Thus, for the support profiles 21a, 21b a material of higher quality can be used than for the walls of profile 22a, 22b In other words, in the configuration according to the invention of the mast 2, 2 ', 2 "a discretionary combination of materials and the selection of a suitable joining technology for this is possible.

Likewise, by means of the simple construction configuration of the mast 2, 2 ', 2' 'for the end of the connection between the support and guide body 35, 37 as well as between the support profile 21a, 21b and the mounting plate 23a, 23b Different bonding technologies can be used.

If the support profile 21b and the profile wall 22a, 22b are detachably connected to each other by connecting elements 38, after the disassembly of a profile wall 22a, 22b of the support body 35 or before the assembly of a profile wall 22a, 22b in the support body 35, the internal space of the mast 2, 2 ', 2 "is freely accessible from the outside and components such as a control, regulation or drive technique and the like can be introduced without problems into the interior space Therefore, the already existing interior space of the mast 2, 2 ', 2 "is used and the construction size of the handling apparatus 1 is reduced.

If the support and guide body 35, 37 and the support profile 21b and the profile wall 22a, 22b are detachably connected to each other by joining elements 36, 38, a damaged profile wall 22a, 22b can be replaced or a damaged support profile 21b or a damaged guide body 37. It is not necessary to replace the entire mast 2, 2 ', 2 "which, if any, is damaged only locally, but only the damaged construction parts thereof. If it is damaged, for example, one of the profile walls 22a, 22b, is only this profile wall 22a, 22b has to be replaced, the other profile wall 22a, 22b, the support profile 21b and the guide body 37 have a sufficiently high dimensional stability, such that the profile wall 22a can be removed , 22b damaged without the mast 2, 2 ', 2 "bending over itself. Thus, with the least complexity of time and cost, a new profile wall 22a, 22b can be applied to the support body 35 and the downtime of the handling apparatus 1 can be reduced to a minimum.

The mast 2 (2 ', 2 ") is made in the form of a light construction, for which the profile walls 22a, 22b are provided with recesses 57, for example, triangular, as drawn in Figures 1 and 2. The recesses 57 arranged spaced apart in the longitudinal direction of the mast 2 (2 ', 2 "), on the other hand, can also be configured in a rectangular manner, as drawn with dashed lines in Figure 2. In this regard, the recesses 57 respectively have a passage surface 58 that is preferably formed by a section of bent wall with respect to the profile wall 22a, 22b approximately 90 °. Additionally, the recesses 57 may have handles 59 which are preferably formed by a section of bent wall with respect to the profile wall 22a, 22b approximately 90 °. In this way, an additional auxiliary climbing means or ladder can be dispensed with, which is usually fixedly mounted on the rear side of the mast 2 (2 ', 2 "). The bent wall section stiffens the profile wall 22a, 22b , in such a way that no damage is produced by a maintenance staff that can scale the mast 2 (2 ', 2 "). On the other hand, step slats or handles can be applied to the wall parts that delimit a recess 57

In Figure 7 the mast 2 (according to the embodiment according to Figure 4) is shown in a top view for the handling apparatus 1 with the lifting device 3. The lifting device 3 presents the drive of traction means 45 and the lift carriage 60 that can be moved therethrough the guides 46a, 46b in the vertical direction (Y direction).

The traction means drive 45 comprises in the mast foot area in the mast body a first reversing pulley 61 rotatably housed, a second reversing pulley 62 rotatably housed in the mast head area in the mast body and the traction means 55 guided around the

themselves as well as a lifting drive 63. The reversing pulleys 61, 62 are rotatably housed through support devices 64, 65 at the foot of the mast and the head of the mast.

In a preferred embodiment, the traction means 55 is formed by a toothed belt and the reversing pulleys 61, 62, by toothed transmission pulleys. Similarly, the pulling means 55 may also be formed by a chain, a cable and the like.

As shown in Figure 2, the mounting plate 23a adjacent to the lift carriage 60 is equipped with the support device 64 in which the first reversing pulley 61 is housed. In the area of the head of the mast is fixed a support device 65 schematically indicated in Figure 1, for example, is screwed to the guide body 37 in which the second reversing pulley 62 is housed.

As shown in Figures 1 and 7, the support shafts 66, 67 of the reversing pulleys 61, 62 are aligned perpendicularly with respect to the central plane 50 of the mast 2 and are arranged between the supporting profiles 21a, 21b held at distance. The drive means 45 can be structured particularly easily when the support shafts 66, 67 are arranged vertically one above the other.

According to a first embodiment, the lifting drive 63 is also fixed through a clamping bracket 68 in the area of the mast foot on the mast 2. The lifting drive 63 is coupled to the first reversing pulley 61 through a drive shaft 70.

Although in the preferred embodiment the lifting drive 63 is fixed on the mast, according to a second embodiment (not shown) it is possible that the lifting drive 63 is fixed on the translation mechanism 4 and that the drive shaft of the lifting drive 63 and a drive shaft 70 of the first reversible pulley 61 that can be driven can be joined through a coupling drive for transmission of the torque, for example a drive with traction means and the like.

The lifting drive 63 is preferably formed by an electric motor, particularly an asynchronous motor, synchronous motor and the like.

As can be seen from the overall view of Figures 7 and 8, the ends of the traction means 55 are connected through a tension device 71. The tension device 71 has a base part 73 and a carriage of tension 75 adjustable with respect thereto through an adjustment element 74, particularly an adjustment screw. The first end of the traction means 55 is connected through a clamping device 76 with the base part 73 and the second end of the traction means 55, through a clamping device 77 with the tension carriage 75. By The tension device 71 can precisely adjust the pre-tension of the traction means 55, particularly a belt tension. The adjustment of the belt tension is usually relatively complex in practice and the mast 2 according to the invention is characterized in that the same together with the drive means drive 45 an independent construction unit. Therefore, for transport purposes the mast 2 and the lower translation mechanism 4 can be transported separately from each other to a place of placement and mounted in place until giving the handling unit 1.

The lifting carriage 60 is equipped with a mounting element 81, particularly an approximately U-shaped mounting bracket in the cross-section, which is fixed through a fixing device in the tension device 71, particularly the part of base 73. The fixing device has several connecting elements 82, by means of which the lifting carriage 60 and the tension device 71 are detachably connected to each other. The connecting elements 82 are formed, according to this embodiment, by screws .

According to this embodiment, a mounting plane (mounting interface) is configured between the lifting carriage 60 and the tension device 71. Therefore, the lifting carriage 60 can be separated very simply and quickly from the traction means drive 45 with the housing frame. The pre-tension in the traction means 55 does not have to be released to engage the carriage of elevation 60 together with the housing frame to the drive of traction means or to decouple it from the drive of traction means.

As can also be seen in the joint view of Figures 7 and 8, the lift carriage 60 has a lift frame 86 housed on the guide slides 47a, 47b, 47c through guide wheels 83a, 83b, 84a, 84b, 85a, 85b and a housing frame 96. The lift carriage 60 is supported with its guide wheels 83a, 83b, 84a, 84b, 85a, 85b on the guide slides or raceways 46a, 46b, 46c and It can be moved in a vertical direction (Y direction) through the drive means.

As can be seen well in Figure 7, a first branch of the traction means 55 is driven through the internal space of the mast 2 and a second branch of the traction means 55, outside the mast 2 between the guides 46a, 46b . By this measure, a gap 78 can be reduced between a vertical reference axis (neutral fiber) located in the center of the mast 2 area and an axis in the load center in the housing frame 96.

The housing frame 96, as shown in more detail in Figure 9, has supporting arms 87 arranged with separation 97 in parallel with each other, approximately L-shaped and made

In a lightweight construction form. The ends of the support arms 87 that protrude in the lifting frame 86 are connected to each other through a profile crossbar 88. The support arms 87 have perforated profile bars for weight savings.

As shown in Figure 9, the housing frame 96 can be rotated through an adjustment device 89 with respect to the lifting frame 86, particularly around an axis of rotation 90. Thanks to the relative graduation it can now be adjusted advantageously an assembly plane 91 in the housing frame 96 to a preferably horizontal reference plane.

According to this embodiment, the adjustment device 89 has a rotation support 92 and a locking device. The locking device has, according to the representation shown, locking screws 93, by means of which, after adjustment of the mounting surface 91, the adjusted relative location between the lifting frame 86 and the housing frame 96 is fixed, particularly the arms of the supporting arms 87 erect arranged on both sides with respect to the lifting frame 86.

In the same way it is also possible to use, instead of the locking screws, ratchets, securing bolts, clamping devices or tension. It should only be ensured that after the adjustment of the mounting plane 91 the relative location between the lifting frame 86 and the housing frame 96 is fixed.

The adjustment device 89 may additionally have an adjustment device 94 which can be used for an exact adjustment of the mounting surface 91 with respect to a reference plane, and the relative location adjusted by means of the locking device is fixed as soon as The assembly plane 91 has been adjusted with respect to the reference plane. The adjustment device 94 has at least one adjustment element 95 that allows a relative graduation between the lift carriage 60 and the housing frame 96 and that joins them together. Therefore, the mounting surface 91 can be adjusted with respect to a reference plane (horizontal). According to the embodiment shown, the adjustment device 94 has two adjustment elements 95 which are formed, for example, by adjustment screws. These adjustment screws are housed in a console 98 and their screw heads rest respectively on the upright branch of the support arms 87. On the other hand, the adjustment element 95 may also be formed by an adjustment drive, for example, a hydraulic drive

The at least one adjustment element 95 also serves so that, after loosening the locking screws 93, the housing frame 96 can move only a certain adjustment angle with respect to the lifting carriage 60. As a consequence, thanks to the element The adjustment range 95, particularly a rotation angle, of the housing frame 96 with respect to the carriage 60 is defined.

If the mounting surface 91 was adjusted through the adjusting device 94 with respect to a reference plane, the relative location between the lift carriage 60 and the housing frame 96 is fixed detachably through the mounting device. locking, particularly by tightening the locking screws 93.

In another embodiment not shown, the adjustment device 89 has an adjustment drive, for example, a hydraulic drive and the like that causes the relative graduation between the lifting frame 86 and the housing frame 96.

An optionally independent invention is described by Figures 8 to 10, according to which the support arms 87 are equipped, respectively, with mechanical mounting interfaces 99 that can be graduated relatively from each other. Each support arm 87 is made in a lightweight construction form and has profile walls 101 arranged spaced apart by spacers 100. According to the embodiment shown, profile walls 101 are joined together through joining elements 102 until giving a supportive arm 87.

The mounting interfaces 99 have, respectively, an approximately T-shaped mounting base 103 in the cross-section, which can be moved along guide surfaces 104 relative to the support arm 87. The support arms 87 configure, on a side opposite the guide surface 104, a guide surface 108, against which the counter bases 109 approximately T-shaped can be supported in the cross-section. The guide surfaces 104, 108 are configured on opposite sides of each other of branches arranged on both sides with respect to the lifting frame 86, and protruding therefrom from the cantilever arms, the support arms 87 or their profile walls 101 having a parallel tour

The mounting brackets 103 configure the mounting surface 91 described above on its upper side.

Additionally, the mounting interfaces 99 have, respectively, a positioning pin 105 that fits into complementary openings of a load bearing device 106 drawn with dashed lines and dots in Figure 8 for storage and removal of goods in bales (not shown) on or from a shelf shelf.

The mounting interfaces 99 can also have a blocking device, respectively, by means of which the mounting base 103 can be fixed in its relative location.

In this way, a gap 110 between the mounting interfaces 99 or the mounting bases 103 can be adjusted such that load bearing devices 106 of different construction classes, weight classes and the like can be accommodated.

In Figure 11 another embodiment of a 2 '' mast is shown for a handling apparatus 1 which forms a hollow profile shaped body in the form of a light construction.

The mast body has a support body 35 '' 'and two guide bodies 37' '' that are joined together in separation planes 48 that are between them in the longitudinal direction of the mast 2 through joining elements 36 detachable or permanently through assembly joints.

The support body 35 '' 'is composed of profile walls 22a "', 22b '' 'which are designed, respectively, in an approximate C-shape and at their free ends are provided with projecting flanges 40 that protrude at right angles on a profile wall part 39.

The guide bodies 37 '' 'are designed according to the embodiment according to Figure 4. The support body 35' '' and the guide body 37 '"are joined in the separation planes 48 in the area of the flanges of connection 40, 51 through the connection elements 36 to give a mast body with dimensional stability, particularly with flexural and torsional stiffness.The connection elements 36 are formed, according to this embodiment, by screws separated in the longitudinal direction of the mast 2, such that the support body 35 '"and the guide body 37"' are detachable together.

Similarly, however, it is also possible that the support body 35 '"and the guide body 37'" are permanently attached to each other through assembly joints, particularly a weld, indirect or adhesion weld bead or by pressure bonding (riveting).

According to this embodiment, the lifting device 3 has two lifting carriages 60 (not shown) and traction means drives 45. The drive means drives 45 are made according to the above description and have, respectively, at least one means of traction 55, whereby a lifting carriage 60 can be adjusted respectively along the guides 46a '' ', 46b "' in a vertical direction.

The examples of embodiment show possible variants of embodiment of the mast 2, it being noted at that point that the invention is not limited to the variants of embodiment especially represented therein, but rather that various combinations of the individual variants of embodiment are also possible between yes and that this possibility of variation, due to the teaching for the technical procedure by the object invention, belongs to the knowledge of the expert active in this technical field. Therefore, all conceivable variants of embodiment that are possible by combining individual details of the embodiment variant represented and described are also included in the scope of protection.

For reasons of order it is finally pointed out that for the better understanding of the structure of the handling apparatus 1 and the mast 2, its constituents have been partially represented not on a scale and / or in an enlarged and / or reduced form.
