Description

Conveyor system for an assembly line

The invention relates to a trained according to the preamble of claim 1 conveyor system for an assembly line.

A conveyor system of the type mentioned in the introduction is e.g. from EP 1 744 443 AI known.

Such a conveyor system is used, for example, in automobile manufacturing to sequentially mount automobiles as products to be mounted along an assembly line. Due to the size and manageability of the particular assembly object (e.g., a car body), it is advantageous to receive the assembly object on a transport means (also called skid) and move the transport means along a path through a conveyor track, such as a skid. to transport a roller conveyor, a belt conveyor or a slat conveyor, predetermined routing.

Especially in operations with historically grown structures, however, the ergonomic situation in the field of such assembly lines is often still difficult because the transport facilities have no or only about manual adjustment (eg for a height adjustment) and therefore also no power supply. However, the increasing demands in recent years in terms of ergonomics and flexibility as well as productivity can make it increasingly necessary that the transport devices are equipped motorically adjustable to ensure time-saving optimal accessibility on all cycles of the assembly line.

This can, if the complete old systems dismantled and new systems must be built, be associated with considerable financial and technical effort.

An alternative exists in the conversion of the existing old plants. Of particular importance is that the basic dimensions of the recent narrow transport devices can be maintained and as few disturbing or disturbing the assembly process new contours (interference contours) arise. In this context, lifters and transfer points are also to be taken into account, which due to their function must find similar geometries.

The invention is therefore based on the object of providing a conveyor system according to the preamble of claim 1, which is set up in such a way that, while maintaining predetermined basic dimensions, a power supply for the transport device (s) is ensured and yet a low-disassembly assembly is ensured.

This is achieved with a conveyor system according to claim 1. Further developments of the invention are defined in the dependent claims. According to the invention, a conveyor system for an assembly line comprises: one or more conveyor (s) arranged to receive a product to be mounted thereon, a conveyor track arranged to transport the conveyor (s) along a defined path of the conveyor track to lead in a conveying direction, a power supply, which is arranged laterally next to the conveyor track and which extends longitudinally along the route of the conveyor track, wherein each transport device has a laterally beyond the conveyor track out horizontally projecting pickup device, which is arranged above the power supply and set up is to remove electrical energy provided by the power supply and to transmit to the transport device. The conveyor system according to the invention is characterized in that the power supply is arranged in a laterally adjacent to the conveyor track and along the route of the conveyor track extending bottom portion or laterally grown, so that the power supply vertically not over an upper surface of the bottom portion or the existing conveyor track protrudes beyond.

Due to the lateral arrangement of the pickup device, it is possible in a simple and cost-effective manner to retrofit a power supply for motorized transport devices in an already existing conveyor track, such as a roller conveyor, a belt conveyor, a plate belt or the like. The existing conveyor track is essentially only equipped with new, now motor-adjustable transport facilities. equip, which each have a pickup device according to the invention. The existing conveyor track can continue to be used with minor adjustments.

Characterized in that the power supply is embedded in the bottom portion, so that it does not protrude vertically beyond the upper surface of the bottom portion, this does not represent the assembly process on the assembly path obstructing contour. Only the laterally projecting pickup device is in the assembly process of assemblers as However, this has hardly any effect because the body is usually much wider than the transport device. Since, as stated, the pickup device is arranged "in the shade" of the body, the risk of tripping is negligible.

This can be done with the conveyor system according to the invention in compliance with e.g. guaranteed by an existing conveyor system basic dimensions a power supply for the transport device (s) and at the same time a low-disassembly assembly can be ensured.

Characterized in that the power supply is mounted laterally on the conveyor belt, so that it does not protrude beyond the upper surface of the conveyor belt, this does not constitute the assembly process substantially obstructing contour.

Each transport device preferably has an integrated scissor-lift driven by a belt driven by a motor. on table over which a vertical height adjustment of the transport device is realized. Such a scissor lift table is very flat, so that it can have the same dimensions and tolerances as a rigid structure integrated in the existing old conveyor system. This allows existing handling devices, such as robots, easily connect to the conveyor system according to the invention.

According to one embodiment of the invention, the bottom portion is vertically adjustable in height.

Thus, a vertical distance of the bottom portion of the pickup device can be easily fine-tuned to ensure optimum power collection. This is particularly advantageous because when using already existing structures of a historically grown conveyor system certain structural and dimensional basic conditions can not be changed without much effort. Due to the height adjustability of the bottom section, which e.g. can be introduced later in the existing structures in the context of the reconstruction, height differences caused by the grown structures can be compensated in a simple manner.

According to a further embodiment of the invention, the pickup device has a horizontal pickup surface arranged at a predetermined vertical distance from and facing the upper surface of the bottom section, the pickup device having a peripheral edge around the pickup surface, which extends vertically so as to bridge the vertical distance.

Due to the circumferential edge bridging the vertical distance, which is preferably made of a material that is to some extent elastic but nevertheless resistant to bending, deposits between the upper surface of the bottom section and the pickup surface of the pickup device can be avoided. Entering the pickup device is not intended or even prohibited. The material stiffness is preferably chosen so that sufficient rigidity is present to withstand accidental, short-term entry by a person without plastic deformation.

The peripheral edge is preferably made of plastic, such as rubber. According to another embodiment of the invention, a portion of the peripheral edge facing the conveying direction of the conveying path obliquely extends at a predetermined angle in a direction rearward with respect to the conveying direction of the conveying path, with a rear portion relative to the conveying direction of the conveying path of the peripheral edge extends obliquely by a predetermined angle in a direction with respect to the conveying direction of the conveying path forward direction. In other words, when viewed from above, the picking device has the shape of an isosceles symmetrical trapezoid, with the peripheral edge extending around the two legs and both parallel sides of the trapezoid. .

By the oblique legs (the front and the rear portion of the peripheral edge) impurities of the bottom portion (eg small parts such as screws) can be reliably conveyed laterally away from the pickup device in a movement of the transport device in the conveying direction or against the conveying direction, so that the risk of between the bottom section and the pick-up device is possible effectively reduced clamping of these contaminants.

In accordance with yet another embodiment of the invention, a brush arrangement bridging the vertical distance is provided at the front and rear of the customer surface in relation to the conveying direction of the conveyor track.

By the front and rear provided brush arrangements can be better ensured that impurities of the bottom section can not get caught between the bottom portion and pickup and jammed. Rather, the bottom portion is virtually swept away by the brush assemblies and thus reliably kept clean in connection with the lateral removal of the contaminants through the oblique legs of the pickup device.

According to one embodiment of the invention, the pickup device has a top surface with a first surface portion inclined toward the bottom portion relative to a horizontal plane from the transporting means, the first surface portion being oriented relative to the horizontal plane in the direction to the bottom portion inclined and with respect to the conveying direction of the conveyor track forwardly extending second surface portion and a relative to the horizontal plane towards the bottom portion inclined ter- and with respect to the conveying direction of the conveyor track to the rear extending third surface portion of the upper surface of the pickup connect. Due to the oblique configuration of the upper surface of the pickup device falling objects from above can be reliably kept away from the area of the bottom portion and cleared from this. Through the first surface portion sliding objects or small parts slip through its slope laterally out of the region of the bottom portion. Through the second or the third surface portion sliding objects or small parts slip through the slope of one of the oblique legs of the pickup and are reliably cleared from the peripheral edge of the area of the bottom portion.

According to yet another embodiment of the invention, a first transmitting and receiving device is further embedded in the bottom section, wherein the pickup device further comprises a second transmitting and receiving device, and wherein the first and the second transmitting and receiving device Device are set up to exchange bidirectional data with each other.

With this embodiment of the invention, non-contact data from the transport device to a computer unit and also data from the computer unit the transport device are transmitted. Preferably, the arithmetic units are installed on the transport device, in which tables that establish a relationship between assembly clock and lifting height are stored, while the first section located in the bottom section at each clock transmitting and receiving devices only only clock numbers, ie location addresses contained in the Passing by are read out.

According to a further embodiment of the invention, the pickup device and the power supply are arranged so that the decrease of electrical energy by the pickup device takes place without contact. Preferably, the decrease of the electrical energy takes place inductively, wherein the pickup device is equipped with an induction pickup, and wherein the power supply comprises induction lines which are incorporated in the e.g. made of wood floor section are embedded or constructed according to the invention.

Due to the non-contact transmission of electrical energy, the pickup device is particularly low maintenance and insensitive to contamination. Furthermore, there are therefore no exposed electrical contact paths in the mounting area, which could represent a source of danger.

According to yet another embodiment of the invention, the conveyor track has a conveyor track bottom arranged below the transport device, wherein the conveyor track is set up in such a way that the transport device, when guided along the route, has a relative position corresponding to the route guidance. movement is carried out with respect to the conveyor track floor, and wherein at a bottom of the transport device on a front in relation to the conveying direction of the conveyor line longitudinal end of the transport means is provided a clearing device which is adapted to take along on the conveyor track soil located debris in the context of their relative movement , Preferably, in addition to the front clearing unit and at the rear longitudinal end of the transport device, a trained in a simplified form rear sweeping unit is provided to ensure a corresponding Räumfunktion even with short sections with reversing. In this case, the conveyor track is designed, for example, as a roller conveyor, so that the transport device is moved along stationary routing rollers of the roller conveyor along the route. In order to ensure an unrestrained transmission of the drive power of the rollers on the conveyor, it is important that the conveyor floor is kept clean and fallen down small parts, such as screws, nuts, clips, etc., are cleared. With the clearing device provided according to the invention, this is reliably ensured.

According to one embodiment of the invention, the clearing device has a clearing blade extending transversely to the route path of the conveyor track and having two clearing plate legs which are arranged connected to one another at an angle to each other, so that they can move between them in relation to the conveying direction of the conveyor belt. train to the rear to form a closed rejuvenating space.

In the tapered space for evacuation, the debris entrained by the broaching device can be concentratedly collected at a position to facilitate final removal of the contaminants. According to a further embodiment of the invention, the broaching device additionally or alternatively has a brush cascade extending transversely to the route of the conveyor track, wherein a vertical distance from the brush cascade forming parallel to each other and running transversely to the route guidance

Brush elements from the conveyor track floor in relation to the conveying direction of the conveyor track decreases towards the rear.

The brush cascade preferably has 3-5 parallel brush elements and should store objects in addition to the cleaning function for the conveyor track floor and allow rolling movements of small parts at edges. This makes it possible to carry small parts such as screws over long distances on the conveyor floor.

According to yet another embodiment of the invention, the clearing device is vertically adjustable in height. Preferably, the clearing device is additionally or alternatively formed vertically resilient.

In this way, the clearing device can be optimally employed on the conveyor track floor and on the suspension a predetermined contact force on the conveyor track floor be exercised. This additionally improves the clearing function of the clearing device.

In accordance with yet another embodiment of the invention, the conveyor track floor defines a floor level, the floor level having one or more interruption areas so that debris entrained by the broaching device as it moves relative to it moves vertically downwards over the interruption area or zones can be discharged from the ground level out. Each interruption area is preferably designed in the form of a depression and / or in the form of a recess in the conveyor track bottom. In this way, the contaminants collected by the clearing device can be reliably removed permanently from the ground plane of the conveyor floor to be kept clean. In the following the invention will be described in more detail by means of preferred embodiments and with reference to the attached figures.

Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with the embodiments illustrated in the drawings.

FIG. 15 shows a schematic side view of an impurity disposal area for the conveyor system of FIG. Embodiments of the assembly line conveying system according to the present invention will now be described with reference to FIGS. 1-14. Figures 1-15 show, according to an embodiment of the invention, a conveyor system 1 of an assembly line for mounting automobiles (as products to be mounted).

As shown in FIGS. 1-5, the conveyor system 1 has a plurality of transport devices 10 (only one shown in the figures), on each of which an automobile body 100 to be subjected to an assembly process can be received, and a conveyor track 20 constructed here in the form of a roller conveyor on, which is arranged to guide and transport each transport device 10 along a defined route of the conveyor track 20 in a conveying direction Rl. Such a route is e.g. in Fig.l of the document

EP 1 744 443 A1.

In other words, according to the embodiment of the invention shown in the figures, the conveyor track 20, which is configured as a roller conveyor in such a way that each transport device 10 during guiding and transporting along the route guidance relative movement with respect to the conveyor track 20 corresponding to the route guidance carries

Each formed as a so-called skid or skid frame transport devices 10 each have a very flat scissor lift 11, which hardly allows ground clearance between the sideboards and which optionally via a gear (not shown) provided electric motor 12 and not shown drive belt for lifting and Lowering (according to the double arrow in Figure 2) is driven. The electric motor 12 is attached to the transport device such that it lies in the region of an axle or a wheel housing or an alternative recess of the automobile body 100 and thus forms no contour that obstructs the assembly process or increases a height dimension of the transport device 10 and the automobile body 100 when the scissor lift table 11 is lowered.

The scissor lift table 11 is an internal lifting device. To protect ontage persons from danger spots, the entire surface of the transport device 10 is covered and the scissors of the scissor lift table 11 is shielded with a bellows against contamination and access.

To control the electric motor 12, the transport device 10 further comprises a computer 13 (see Figure 11), which is arranged in the same space-saving and disability-poor manner as the electric motor 12.

In order to supply the electric motor 12 and the computer 13 with electrical energy, the conveyor system 1 also has a power supply 30 (FIG. 4) and a transport device 40 on the transport device 10.

The power supply 30 is arranged laterally next to the conveyor track 20 and extends longitudinally along the routing of the conveyor track 20. The power supply has two current-carrying induction lines (or line conductors) 31, 32 which are arranged in a laterally adjacent to the conveyor track 20 and along along the routing of the conveyor track 20 extending forth- are made of wood-made bottom portion 50 inserted or grown as such, so that the induction lines 31, 32 do not project vertically beyond a flat upper surface 51 of the bottom portion 50 addition.

Trained in the form of a cantilever pickup device 40 projects laterally horizontally from the transport device 10 and beyond the conveyor track 20, so that it is arranged above the power supply 30.

The pickup device 40 is set up to remove electrical energy provided by the power supply 30 and to transmit it to the electric motor 12 and the computer 13 as well as possibly other electrical components of the transport device 10. For this purpose, the pickup device 40 has an induction pickup 41 arranged above the two induction lines 31, 32. Accordingly, the pickup device 40 and the power supply 30 are arranged so that the decrease of electrical energy by the pickup device 40 is non-contact. According to one embodiment of the invention, a radio-wave-based first transmitting and receiving device 33 (eg a transponder) can be integrated in the power supply 30, which is let into the bottom section 50 in the same way as the induction lines 31, 32. Corresponding positionally corresponding thereto, a radio-wave-based second transmit-and-receive device 42 (eg a read / write head) is then integrated into the pickup device 40, wherein the first and the second transceiver device 33, 42 are set up to exchange data bidirectionally by short-range radio transmission. As can be seen in particular in FIG. 7, according to an embodiment of the invention, the bottom section 50 designed, for example, as a narrow pedestal strip can be designed to be vertically adjustable in height in order to finely adjust a predetermined vertical distance AI of the upper surface 51 of the bottom section 50 from a horizontal pickup surface 43 facing the latter Allow pickup device 40. For this purpose, a height adjustment device 60 is integrated in the bottom section 50, which has two synchronously rotatably drivable threaded spindles 61, 62 and two threadedly connected nut pieces 63, 64, the two nut sections 63, 64 being supported by a support frame construction 65 support the power supply 30 receiving cover plate 50a of Bodenab- section 50.

As can also be seen from FIG. 7, in the region of the connection of the pickup device 40 to the transport device 10, the pickup surface 43 has a recess 43a for receiving a laterally external longitudinal guide of the conveyor track (here the roller track) 20.

The floor section 50 is stably supported so that it can be walked on by assemblers. As can be seen from FIG. 5, in part two further working platforms 70, 71 are provided, which expand the area accessible by assembly persons. According to one embodiment of the invention, the bottom portion 50 may be about 400 mm wide, wherein the vertical distance AI to the pickup 40 is about 8 mm.

As can be seen in particular from FIGS. 8-12, the pickup device 40 has an edge 44 that extends around the picking surface 43 and extends vertically so as to maintain the vertical distance AI between the upper surface 51 of the bottom section 50 and the pickup surface 43 of the pickup device 40 bridges. The peripheral edge 44 is made of different materials. The outside 44b is made of rubber material. Here, the rubber material is in z-

Direction yielding trained to survive accidental onset of a worker harmless. Due to the lateral space problems, the outside 44b is also narrow. The oblique sides 44a and 44c have a brush arrangement. The inside 44d, which is the boundary to the recess 43a, is formed of sheet metal because it does not have to be compliant and at the same time constitutes the support structure for the cover of the pickup device.

As can be seen in particular from Fig.10, 11 and 12, extending in relation to the conveying direction Rl of the conveying path 20 front portion 44a of the peripheral edge 44 of the transporting T 10 by a predetermined angle obliquely in a with respect to the conveying direction Rl the conveying path 20 rearward direction or obliquely opposite to the conveying direction Rl, wherein a with respect to the conveying direction Rl of Conveyor track 20 rear portion 44c of the peripheral edge 44 of the transport device 10 by a predetermined angle obliquely in a relation to the conveying direction Rl of the conveyor track 20 forward direction or obliquely in the conveying direction Rl extends. The front portion 44a and the rear portion 44c are connected to each other via a parallel to the conveying direction Rl extending central portion 44b of the peripheral edge 44.

In other words, as viewed from above (see, for example, Fig. 8), the pickup device 40 has the shape of an isosceles symmetrical trapezoid with recesses 43a, with the peripheral edge 44 extending around the two legs and the parallel sides of the trapezoid.

By the oblique legs (the front portion 44a and the rear portion 44c of the peripheral edge 44) the soil portion 50 contaminating objects G (eg small parts such as screws) in a movement of the transport device 10 in the conveying direction Rl (or counter to the conveying direction Rl) as in 8 can be reliably conveyed laterally away from the pickup device 40 by the bent arrow, so that the risk of jamming of these articles G between bottom section 50 and pickup device 40 is effectively reduced. As can be seen in particular from FIG. 8 and FIG. 10, at the pickup surface 43 with respect to the conveying direction R1 of the conveying path 20, front and rear (ie behind the front section 44a and the rear section, respectively 44c of the peripheral edge 44) each provide a vertical spacing AI bridging brush assembly 45, 46 in the form of a brush strip. As can be seen in particular from FIGS. 9 and 10, the pickup device 40 has an upper surface 47 formed by a deck covering with a first surface section 47a inclined towards the bottom section 50 relative to a horizontal plane, with the first section 47a being inclined towards the bottom section 50 Surface portion 47a is a relative to the horizontal plane towards the bottom portion 50 and inclined towards the conveying direction Rl of the conveyor 20 to the front or in the conveying direction Rl extending second surface portion 47b and relative to the horizontal plane towards the bottom portion 50 towards inclined and in Reference to the conveying direction Rl of the conveyor track 20 to the rear or opposite to the conveying direction Rl extending third surface portion 47c of the upper surface 47 of the pickup 40 connect.

Due to the oblique configuration of the upper surface 47 of the pickup device 40, articles G falling down from above can be reliably kept away from the region of the bottom section 50 or cleared of it. Objects G falling on the first surface section 47a slip laterally out of the region of the bottom section 50 as a result of the bevel thereof, as indicated by the curved arrow in FIG. Objects G falling on the second or the third surface section 47b or 47c slip through their bevel in front of one of the oblique legs of the trapezoidal cutters. Mereinrichtung 40 and are reliably cleared from the area of the bottom portion 50 of the peripheral edge 44. With particular reference to FIGS. 3 and 11-15, the conveyor track 20 has a conveyor track bottom 21 arranged below the transport device 10, so that each transport device 10 is moved relative to the conveyor track bottom 21 while being guided along the route corresponding to the route guidance.

On an underside of the transport device 10, a clearing device 80 is provided on a front longitudinal end 10a of the transport device 10 with respect to the conveying direction R1 of the conveying path 20, which is arranged on the conveyor track bottom 21 impurities or objects G (see Fig.15) As part of their relative movement to take along. The clearing device 80 is provided in particular because an existing vertical distance A2 (see FIG. 13) between the transport device 10 and the conveyor track bottom 21 is relatively small due to the construction of the scissor lift table 11 and should therefore be kept free from any contamination since the rollers the conveyor 20 otherwise can not provide propulsion.

In detail, the clearing device 80 has a clearing blade 81 extending transversely to the route of the conveyor track 20 with two Räumschildschenkeln 81a, 81b, which are connected to each other at an angle to each other, so that between them one with respect to the conveying direction Rl of the conveyor track 20 after behind the back, forming a tapered space VI. In other words, the preferred central clearing blade 81 is inclined inwards, so that the objects G are collected in the Räumraum VI and not distributed.

The blade 81 made of plastic clearing device 80 is vertically adjustable in height and formed vertically resilient, as indicated by the double arrow in Fig13. For this purpose, the plow blade 81 between two longitudinal beams 10 b, 10 c of the transport device 10 is arranged, wherein it is guided on two rigid guide rails 82, 83 and resiliently mounted on two springs 84, 85. The plow blade 81 is preferably beveled on the sides in accordance with the quality of the conveyor track 20. For a lowest position of the

Blade 81 comes e.g. the lower edge of skids lOd of the transport device 10 into consideration.

As can be seen in particular from FIG. 3, FIG. 13 and FIG. 15, the conveyor track bottom 21 defines a ground plane El which has a plurality of interruption areas 22 in the form of recesses 22a and / or in the form of recesses 22b in the conveyor track floor 21, so that dirt or objects G entrained by the broaching device 80 as part of their relative movement can be discharged vertically downwards out of the ground plane E via the interruption regions 22, as indicated by the curved arrows in FIG. The bottom portion of the recess 22a is formed in the direction of conveyance R considered steadily ascending. The risk of crushing a worker is significantly reduced. In addition or as an alternative to the space shield 81, the clearing device 80 may have a brush cascade 86 extending transversely to the route of the conveyor track 20, whereby a vertical distance of the brush cascade 86 from the conveyor track floor 20 to the brush cascade 86 forming parallel to each other and transverse to the route Relative to the conveying direction Rl of the conveyor track 20 decreases toward the rear. The brush cascade 86 is mounted vertically feathers on the underside of the transport device 10, for example, two brackets 88, 89 made of spring steel strip.
