Description

CONVEYING DEVICE WITH ONE FLAT

EXTENDED SUPPLY ORGAN

The invention relates to the field of conveyor technology and relates to a conveyor, comprising:

two spaced side runners extending along a direction of conveyance,

- A circumferentially extending between the Seitenabschlussträgern, extensively extended conveyor member having an upper conveyor section and a lower return section,

- Two spaced apart in the conveying direction head ends, wherein the conveying member is deflected in each case at the head ends,

a support arrangement arranged between the side end supports and the head ends for supporting the conveyor section, and

- At least one drive device with at least one drive motor for driving the conveying member. Conveying devices with a circumferential, flat-extended conveying member such as conveyor belt or mat chain are known in the art. The conveying members are usually driven at one or two deflection points by means of a deflection shaft. To support the conveying member in the region of the upper conveyor section, on which the conveyed material rests, the conveying member between the deflection z. B. slidably guided on slides. There are also known conveying devices in which the conveying member rolls on roller bodies between the deflection points. Such a conveyor is z. As disclosed in WO 2010/148523. The aforementioned conveyors are used for example as a worker Mitfahrbänder use. The height of such Mitfahrbänder should be as low as possible. So today conveyors are common, which have a maximum height of 120 mm to 170 mm for the said use. In this dimension, the free height between the ground support and the return section of the conveying member is included. However, the comparatively low overall height poses a challenge, in particular with regard to the design and construction of the drive device.

DE-C-44 07 163 describes a generic conveyor with a circulating around two deflection axes conveyor belt. The conveyor belt is driven via one of the deflection axes, wherein the drive motor is arranged outside the driven conveyor belt. The deflection axle is driven by a gear drive with chain drive. Although a drive device arranged outside the conveyor region allows a low overall height of the conveyor for that area. which forms the conveying surface, such a conveyor is neither compact nor space-saving. A compact and space-saving construction requires that the drive units with drive motor and gearbox are arranged between the conveying and return section of the conveyor element and between the side end supports.

DE-U-93 16 012 also deals with the problem of the limited space between the conveying and deflection section of the circulating guided conveyor belt of a conveyor. The conveyor belt wraps around a drive wheel in the deflection section. The drive motor is located between the conveyor and - J -

guided portion of the conveying member and arranged between the side end supports. For reasons of space, the drive shaft of the drive unit is at right angles to the axis of rotation of the drive wheel. The torque is transmitted via a gear with bevel gear. The conveyor belt is slidably guided over the sidewalls between the deflection areas.

DE 1 887 279 describes a generic conveying device with a circumferential, extensively extended conveying member, which is driven via a deflection axis. The drive motor is disposed between the two IJmlenkbereichen within the conveyor, wherein the device comprises a transmission with drive belt for transmitting the torque from the motor shaft to the driven deflection axis.

DE 1 060 782 also describes a conveying device of the generic type having a circumferential, extensively extended conveying member, which is guided over two deflecting points spaced apart from one another. In contrast to the solutions described above, the conveying member is not driven here in the area of the deflection but in the region of the conveying and return section via a form-fit connection, each with a drive member. The drive members are driven by a drive motor, which is arranged between the deflection points within the conveyor.

DE 10 2006 010 974 describes a conveyor device comprising a conveyor belt and a substantially horizontal guide frame with two seit- lent, horizontally extending in the longitudinal direction of the conveyor belt side cheeks at the ends of a driven by a drive pulley for the conveyor belt is rotatably mounted. The drive is located between the two side bolsters. However, the solutions known in the prior art have disadvantages. Thus, drive units which are arranged within the conveying device, due to their necessarily compact design poor performance. As a result, the length of such conveyors is limited. A modular construction of the conveyor, which is intended to allow large lengths, is therefore hardly feasible by conventional design methods.

It is therefore an object of the invention to provide a conveyor of the type mentioned, which is designed to be compact and in particular has a low overall height.

Other objects of the invention are, for. B. to propose a conveyor, which:

- contains no drive elements outside the head ends and the side termination carrier,

- is modular,

- Can be performed in different lengths, and / or

- can generate sufficient drive power even with larger length. At least one of the objects is solved by the features of independent claims 1 and 16. Further embodiments and developments of the invention will become apparent from the dependent claims, the description and from the figures. The inventive conveyor is characterized in that the at least one drive device:

between the two head ends and spaced therefrom,

- between the two side finalists and

- Is arranged between the upper conveyor section and the lower return section. The drive device further includes a drive member which is arranged circumferentially about two spaced apart in the conveying direction deflecting members and is driven by at least one drive motor. The deflecting elements can be deflection axes.

The revolving drive member in particular forms a conveyor-side section directed towards the conveying section of the conveying member. The conveyor-side section is designed in particular as a drive section.

The revolving drive member further forms, in particular, a return-side section directed towards the return section of the conveying member. The return-side portion of the drive member is the conveyor-side portion of the drive member arranged in particular opposite. The return-side section can also be designed as a drive section.

The drive of the conveying member is done via one or more drive sections of the drive member. The drive member forms with the conveying member in the drive section of a contact closure for transmitting a driving force.

The driving force can be transmitted from the drive member to the conveying section of the conveying member. For this purpose, in particular engaging elements of the drive member and contact elements of the conveying member in the conveying section of the conveying member form a contact closure, in particular an engagement, of the type described below.

The driving force can be transmitted from the drive member to the return section of the conveying member. For this purpose, in particular engaging elements of the drive member and contact elements of the conveying member in the return section of the conveying member form a contact closure, in particular an engagement, of the type described below. The driving force can also be transmitted by the drive member both on the conveyor section and on the return section of the conveying member. For this purpose, in particular engaging elements of the drive member and contact elements of the conveying member both in the return section and in the conveying section of the conveying member form a contact closure, in particular an engagement, of the type described below.

The drive member may form a positive connection for transmitting a driving force from the drive member to the conveying member with the conveying member. The connection can also be non-positive. The compound may also be a combination of positive and non-positive connection.

The drive member can form a flat contact closure with the conveying member for the areal transmission of the driving force. The surface contact closure can also serve the planar support of the conveying member.

The drive member may form a contact closure with the conveying member, in particular an engagement, for transmitting a driving force.

The drive device is spaced from the head ends. The deflection of the drive member is preferably also each spaced from the head ends.

According to a development of the invention, the conveying section is arranged above the drive member. The drive member supports the conveyor section and forms with this in particular at the same time a contact closure, in particular an engagement, for transmitting a driving force to the conveying member.

The drive member contains in particular an endless drive body. The drive body can be formed extensively flat. The drive body can be designed in several parts. The drive body may in particular be a link chain with a plurality of links articulated to each other.

The drive body can also be formed in one piece. The drive body may, for. B. be designed as a band, such as steel strip, belt or rope.

On the drive body, in particular on individual or all members of a link chain, can or may be arranged engagement elements for forming a contact closure, in particular an engagement with the conveying member. The engagement elements are directed in the drive section, for example, to the conveying member.

The engaging elements on the drive body can engage in contact elements on the conveying member. The engagement elements and contact elements therefore have the same pitch, in particular in the drive section.

The engagement elements may in particular be designed so that they overlap the contact elements. The engagement elements engage over the contact elements in particular to the conveying member. The attack is in particular such that the engagement elements secure the conveying member against a, in particular directed perpendicular to the conveying plane, evasive movement away from the drive member.

If the drive member drives the conveying section of the conveying member, then the engaging elements in particular prevent an upward deflection movement.

Does the drive member to the return section of the conveying member. Thus, the engagement elements prevent in particular an evasive movement downwards. As a result, an optimal contact closure between the engagement element and contact element for the purpose of driving the conveying member is ensured.

The engagement elements are characterized in particular by the fact that they actively engage in the drive element in the drive section via the contact elements for the purpose of transmitting a drive force.

The engagement elements in particular form a recess into which in each case a contact element at least partially engages. The engagement elements may be hook-shaped.

The contact elements may be directed towards the drive member, hook-like elements. The contact elements can also be formed by the connecting axes of a link chain.

The contact elements can also be formed by pin-shaped body, in particular pins, on the chain links of the link chain. The pin-shaped bodies may be made of metal, such as steel. The pin-shaped body can be fastened to the chain links via plug connections. The pin-shaped body are characterized by a higher load capacity than, for example, contact elements made of plastic, which are integrally formed on the chain links. The engagement elements may be pivotally mounted on the drive body about a pivot axis. The pivot axis may be a physical axis or even a geometric pivot axis.

As a result, the engagement elements, when they are moved into the drive section, can be pivoted into engagement with the contact elements, in particular. Furthermore, the engagement elements when moving out of the drive section can be active or passive, z. B. by gravity, swing out of engagement with the contact elements. In the drive section, the drive device may include a guide device, in particular a guide rail, which guides, in particular slidably guides, the engagement elements in the drive section.

The guide serves to determine the pivotal position of the engagement member. Thus, the engaging elements can be pivoted when moving into the Antriebsabsclinitt by the configuration of the guide means into engagement with the contact elements.

The engagement elements can furthermore be held in their engagement position in the drive section, in particular by the design of the guide device, in that the support section is supported in the guide device.

The engagement elements can be when moving out of the drive section through the design of the guide device in particular active or passive, z. B. by gravity, swing out of engagement with the contact elements.

The pivot position is thus determined by the guide of the pivot axis downstream support portion by the guide rail.

The flatly extended conveying member may have a flat bearing surface, i. Conveying level, train for the conveyed. The conveying member may be a conveyor belt.

The conveying member is preferably designed in several parts. The conveying member may in particular a link chain with a plurality of hinged together Be limbs. The conveying member may include a plurality of parallel juxtaposed link chains.

The conveying member, in particular individual or all members of a link chain, may contain contact elements for forming the engagement with the drive member. The contact elements are z. B. arranged on that side of the conveying member, which is opposite to the conveying surface. The contact elements are directed towards the drive member, for example. The link chain of the drive and / or the conveying member may be a modular belt chain, also known as a mesh chain. The links are designed as modular band links.

The modular band members are characterized by a central body. Viewed in the longitudinal extent of the modular belt chain are on the central body on both sides in each case a plurality of projections, for. As prongs or noses, for a meshing engagement with the projections, z. As tines or noses, an adjacent module band member next to each other. The modular belt links are each connected in an articulated manner via a rotation axis. The axis of rotation passes through the mutually engaging in meshing projections.

The engagement between the drive member and the conveying member can be formed by a mutual engagement of depressions and elevations. Accordingly, the engagement elements may be elevations or depressions.

Contact elements on the conveying member and engagement elements on the drive member may in particular be designed to be complementary to one another and arranged so as to form the engagement. Thus, the conveying member may contain elevations and the drive member recesses or vice versa. It is also possible that the conveying member and the drive member each contain both depressions and elevations. These may for example be arranged alternately.

The formed as elevations engagement elements or contact elements may have a main body z. B. of a rubber-elastic material. The main body can be fastened via connecting means on the conveyor or drive member or on its members. The connecting means may include a guided through the body pin. Furthermore, the connecting means may include an external holding plate. The pin is passed through the main body and the retaining plate. The main body is held in this way over the retaining plate.

The pin can be part of a riveted joint. The rubber-elastic body can be fixed under pretension on the conveyor or drive member.

It is also possible that the engagement elements or contact elements are magnetic. Thus, the contact closure or engagement via mutual magnetic attraction of the engagement and contact elements can be formed or at least supported. At least one of the engagement elements or contact elements contains a magnet for this purpose. One of the engagement elements or contact elements may also contain a magnetizable material.

The drive motor can drive a deflection axis of the drive member. It can also be provided that two drive motors each drive a deflection axis of the drive member. The drive motor can be arranged, for example, with its motor shaft coaxial with the deflection axis. The drive device according to the invention can be designed such that it can be operated in two conveying directions, namely in a forward and backward direction. The at least one drive device can be designed, for example, as an intermediate drive. The conveyor may according to still contain a further drive device. This can be designed, for example, as a main drive. The conveying portion of the conveying member corresponds to that portion on which the well to be conveyed rests on the conveying member and is conveyed in the conveying direction. In the return section, the conveying member counter to the conveying direction z. B. returned below the conveyor section. The conveying member is deflected at the head ends of the conveyor section in the return section and vice versa. The head ends may include rotatably mounted deflection axes for deflecting the conveying member.

The conveyor may now include a further drive device with a drive motor which drives the deflection axis at one of the two head ends. Deflection axis and conveying member are arranged cooperating with each other so that the deflection axis can transmit a driving force to the conveying member. This can, for example, via a frictional connection or via a positive, z. B. interlocking engagement between the deflection axis and conveying member.

Both deflection axes can also be driven at both head ends by a drive device described above. The further drive device can be designed as a main drive. The Seitenabschlussträger capture the conveyor laterally. The side finishers may consist of a plurality of longitudinally interconnected longitudinal profiles. The multi-part design of the side termination support allows a modular construction of the conveyor.

The Seitenabschus support may be part of a support frame of the conveyor. The Seitenabschlussträger may be arranged parallel to each other. The side termination beams may form a support frame together with cross members at the head ends and / or cross beams between the head ends.

The drive device and in particular the drive motor is in this case also preferably arranged between the side end supports, between the head ends and between the conveying and return section of the conveying member.

The deflection axes of the drive member can be rotatably mounted via a bearing in brackets. The deflection axes can z. B. be rotatably mounted on ball bearings in the holder. The brackets support the deflection axes. The brackets can in turn be attached to cross members, which z. B. between the side end supports and transverse to these. The cross members in turn may be connected to the side end supports or longitudinal profiles of the side end support.

The deflection axes can be z. B. extend only over a distance between the Seitenabschlussträgern. That is, the deflection axes do not extend to the side end supports. Thus, the end portions of the deflection axes can be rotatably mounted in termination brackets. The brackets can form a sliding surface towards the conveying section of the conveying member, on which the conveying section is slidably guided and supported downwards. Furthermore, sliding rails for a sliding support of the conveyor section can additionally be arranged in the region of the drive device.

The cross members may be or include cross profiles. The cross member may be in one or more parts and, for example, a plurality of longitudinally and / or in the transverse direction of the cross member interconnected Längspro file included. The cross members can run parallel to each other.

At least one drive device of the type described above can form together with the cross members and longitudinal profiles of the Seitenabschlussträger an assembly unit, wherein the spaced-apart longitudinal profiles are connected to the spaced-apart cross members to form a frame. The frame can z. B. be rectangular. Within this framework, the at least one drive device is arranged. Thus, one or more drive devices can be contained in a mounting unit.

The at least one drive device is fastened to the cross members, for example, by means of holders. Thus, the at least one drive device via the deflection axes, which z. B. are rotatably mounted in the brackets, be supported on the cross members.

The mounting unit is characterized in that it is pre-assembled and can be installed in the final assembly as a complete unit in the conveyor. This is done, for example, by connecting the longitudinal profiles of the assembly unit with adjacent longitudinal profiles of the side termination carriers. The mounting unit is preferably correspondingly out of the conveyor again expandable. This is done by the connection between the longitudinal profiles dissolved and the mounting unit is lifted from the conveyor.

The assembly and disassembly of the mounting unit is preferably done with non-mounted conveyor belt. The mounting unit can now be installed at almost any point between the headboards. Depending on the length of the conveyor can be between the head ends also several, z. B. spaced apart mounting units with drive devices. The drive device may include one or more drive motors. The drive motor is, for example, an electric drive motor. The drive motor may in particular be a synchronous, asynchronous or constant-current motor. Thus, the drive motor may be a brushless DC motor (BLDC motor). The drive motor preferably includes a microcontroller for performing engine control functions. The drive motor may in particular contain an electronic speed controller for controlling the rotational speed and / or as a dynamic brake (in English: electronic speed control or ESC). The drive device between the head ends may be designed control technology, for example, as an auxiliary drive, which or the main drives, which z. B. are arranged at the head ends and drive the local deflection axes support drive technology. The largest diameter of the drive motor, including motor housing, for example, 50 to 1 00 mm, in particular 55 to 70 mm.

The conveyor may include a plurality of drive devices arranged one behind the other. The conveyor can several, z. B. contain two juxtaposed drive devices. The conveyor can several contain successively arranged and juxtaposed drive devices. The drive devices may form the support arrangement or a part of the support arrangement. The support arrangement is arranged between the two Seitenabschlussträgem and between the two head ends. The support arrangement may include support rollers, via which the conveying section of the conveying member is supported in a rolling manner.

The support rollers may be passively driven by the conveyor organ, i. be translated into a rolling motion. The drive of the reel body or support rollers is done in particular by the material to be loaded with its weight on the conveyor member on the support rollers, i. presses the conveyor against the support rollers. The support arrangement may comprise a plurality of rotatable rollers, on which the conveying member is supported with its conveyor section rolling. The rollers are preferably distributed over the surface area of the conveyor organ. The rollers can be mounted axially via a physical axis of rotation, wherein the axis of rotation is arranged stationary. The weight load is transmitted via the axes of rotation of the rollers on the support assembly.

The rollers can also be mounted on that side of the conveying member and rotatably mounted thereon, which lies opposite the conveying surface. The rollers move here with the conveyor organ.

The support assembly may also include a plurality of support units each including a plurality of rollers. The rollers are arranged around a support body and roll along a closed orbit this off. The weight load is transmitted via the lateral surface of the rollers from the conveying member to the support body. The rollers are driven by the moving over this conveying member. A conveyor with the support units described is disclosed, for example, in WO 2010/148523 Al.

The mounting unit with the drive device may also include a support arrangement of the type described above. The mounting unit may in particular contain support units for rolling support of the conveyor section. The support arrangement or the support units are respectively arranged between the side end support and the drive element or the deflection axes.

The conveyor can be used to promote bulk or general cargo, such as resting goods or self-moving good. General cargo may be goods or living things, eg. As persons, animals or plants. The conveying surface formed by the extensively extended conveying member may be flat or inclined. The conveying member may be linear in the conveying section.

The conveyor may, for. B. be designed as a moving walk or a walk. Fahrbzw. Forklifts find z. B. Use in airports, shopping malls or train stations to carry people over a longer distance.

Thanks to the rolling support and guidance of the conveying member in the region of the conveying section, the friction is considerably reduced, whereby less powerful and smaller drive motors can be used to drive the conveying member.

Due to the integrated design, in which the drive device and the support arrangement is arranged within the revolving conveyor member and within the side end supports, the conveyor can be made very compact. The conveyor has in particular no outside of the Side termination and the conveyor organ lying, generated by device component interference contours.

Thus, the height and the weight can be kept low, which in turn allows use of the conveyor in tight spaces. So the height from the ground to the conveying surface z. B. only 120 mm.

For reasons mentioned above, the conveyor according to the invention is also used, in particular, as a worker-assisted driving band. Mitfahrbänder be used in industrial manufacturing, in which work steps, such as assembly work, must be made to be moving objects of a production line. In order to give the individual employee enough time to carry out his work steps on the moving object, the employee is moved along a worker's ride-on conveyor parallel to the object in conveying direction. The employee can z. B. be moved synchronously with the object.

Such a worker Mitfahrband can be a length of a few meters, z. B. from 20 to 50 m. A single worker-Mitfahrband can form an assembly, which can be achieved by juxtaposition and possibly common control of several such assemblies far larger distances conveyor.

The conveying device according to the invention can also be used as a loading space conveying device. The loading space conveyor may, for. In a road vehicle such as a truck, a rail vehicle such as a freight car, a watercraft such as a cargo ship, or an aircraft such as an airplane. Furthermore, the cargo hold conveyor can also be used in a cargo or shipping container for loading and unloading the container use. Such containers are used for the transport of goods by road, rail, air or water, and are transported accordingly by road vehicles, rail vehicles, aircraft or watercraft.

Furthermore, the conveyor according to the invention can also be used as a storage room conveyor in a storage system. The storage system is characterized, for example, by a plurality of pallet storage spaces.

FIG. 1 shows an assembly line for assembling automobiles 9. The automobile elements 9 are conveyed along the assembly line in the conveying direction F, while at the same time work steps on the automobile 9 are carried out by the employee 11. On both sides of the assembly conveyor according to the invention 1 are arranged in execution as a worker Mitfahrbänder. The worker-Mitfahrbänder 1 include a revolving conveyor member 2, in the form of a modular belt chain. The modular belt chain forms a flat conveying surface on which the employees 1 1 are moved in the conveying direction F with the cars 9.

The modular belt chain 2 is laterally framed by Seitenabschlussträger 3. 4 and at the head ends 10 a, 10 b by head end cross member 5, 6.

By co-moving the employee 1 1 with the cars 9 in the conveying direction F, the time available for the steps on the cars 9 can be increased.

The inventive worker-Mitfahrband 1 is extremely compact, and in particular has a comparatively low height. Furthermore, the inventive worker car-drive belt does not contain any drive components outside the support frame, which is formed inter alia by the head end crossbeams 5, 6 and the side terminus carriers 3, 4. As can be seen in more detail from FIG. 2, the modular belt chain 2 illustrated schematically forms an upper conveying section 2.1 and a return section 2.2 arranged below the conveying section 2.1. The Seitenabschlussträger 3, 4 are each formed in several parts and consist of a plurality of longitudinal profiles 3.1, 3.2, 3.3; 4.1, 4.2, 4.3 which are connected to each other in the longitudinal direction or conveying direction F.

The conveyor 1 is supported by height-adjustable support legs 7 to the ground. The support legs are attached to the side end supports 3, 4.

At the head ends 10a, 10b, a deflection axis 6a, 6b for deflecting the conveying member from the conveyor section in the return section or vice versa.

The deflection axes 6a, 6b are actively driven by an electric drive motor 7a, 7b. The motor shaft of the drive motor 7a, 7b is arranged in each case coaxially with the deflection axis 6a, 6b.

At the deflection axes 6a, 6b respectively drive members 8 are arranged in the form of gears. The gears 8 form recesses on the conveying member (not shown) a positive engagement, so as to transmit a driving force from the deflection axis 6a, 6b on the conveying member.

FIG. 4 shows a drive device 20 designed as an intermediate drive according to the invention. The drive device 20 includes two, transverse to the conveying direction F extending and spaced apart in the conveying direction F deflection axes 22a, 22b.

Two drive members 23 are viewed in the conveying direction F next to each other around the two deflection axes 22a, 22b arranged circumferentially. The drive members 23 are formed as modular belt chains of a plurality of modular belt members 28.

On the drive side of the modular belt members 28 of the drive member 23 bumps 26 are attached to a base body 37 made of a rubber-elastic material. The bumps 26 are mounted on the modular belt members 28 via pin connections 35.

The pins 35 are guided by an outer plate 37 arranged on the base plate 36 and by the main body 37 itself. The pins 35 connect the plate 36 to the main body 37 and the modular belt member 28 (see FIGS. 5 and 7).

FIGS. 6a to 6d show various embodiments of bumps 81. 82, 83, 84. The bumps 81, 82, 83, 84 are each arranged on a drive member 72, and are in engagement with recesses 85 on the conveying member 71st

The hump 81 according to FIG. 6a has a barrel-shaped curved peripheral surface. The bump 82 of Figure 6b is conical, wherein the base widened starting from the drive member to the outside. The bump 83 of Figure 6c is cylindrical. The bump of Figure 6d includes a magnet 73. In the recess 85 of the conveying member 71 is a magnetizable element, for. B. from a ferrous metal attached. The magnet 73 and the magnetizable element 74 attract each other, thus assisting the engagement. The drive members 23 form a conveyor-side drive section 23.1 and a return-side section 23.2 arranged below the drive section 23.1. On the drive section 23.1 of the conveying section 2.1 of the conveying member 2 is located.

The conveyor member 2 is also formed as a modular belt chain 2 of a plurality of modular belt members 29. The modular belt chain 2 forms in the conveying section 2.1 a flat conveying surface. The modular belt members 29 contain recesses 27 on the side opposite the conveying surface.

The bumps 26 of the drive member 23 now engage in the recesses 27 of the conveying member 2 and form a positive connection for transmitting a driving force from the drive member 23 to the conveying member 2. The rubber-elastic properties of the bumps 26 additionally ensure a frictional or non-positive connection with the conveying member 2.

The one deflection axis 22b of the drive device 20 is driven by means of an electric drive motor 21. On the deflection axis drive elements 30 in the form of drive gears, for transmitting the driving force from the deflection axis 22b provided on the drive members 23 (see Figure 5).

The teeth of the drive gears 30 engage in the deflection in recesses on the modular belt members 28 of the drive member 23. These recesses are arranged on the side of the modular belt members 28, which lies opposite the side containing the Flöcker.

The drive motor 21 is arranged between the two drive members 23 and coaxial with the deflection axis 22b. In principle, both unilinear axes 22a, 22b can each be driven by an electric drive motor. The deflection axes 22a, 22b are supported by brackets 24 freely rotatable and supported accordingly. The deflection axles 22a, 22b are for this purpose via corresponding bearings 25, such as ball bearings, guided by the brackets 24 and rotatably supported relative to these. Thus, several, along the deflection axes 22a, 22b spaced from each other brackets 24 are mounted, which support the deflection axes 22a, 22b over its entire longitudinal extent.

On the outside of the drive member 23 is a respective end bracket 24 'is arranged, which receives the end portion of a deflection axis 22a, 22b. Consequently, the revolving axes 22a, 22b do not extend over the entire transverse extent between the longitudinal profiles 3.2, 4.2 of the side terminus carriers.

The brackets 24 each form a mounting leg 32, via which the brackets 24 and thus indirectly also the deflection axes 22 a, 22 b attached to cross members 53, 54, z. B. are screwed. The cross members 53, 54 in turn are each end to longitudinal profiles 3.2, 4.2 attached to the two side termination carrier, z. B. screwed (see Figure 8).

The holders 24 furthermore each form a sliding surface 33 for the conveying section 2.1 of the conveying element 2 moving over it.

FIGS. 10 and 11 each show a further embodiment of a conveying device 101, 201 according to the invention. Figures 10 and 1 1 show only a cross-sectional view of a section of the range of the drive device 1 1 0, 210. Basically, the structure of the conveyor 101, 201 with the exception of the particular distinguishing features shown in Figure 10 and 1 1 the construction of the conveyor according to the Figures 1-4 and 8-9 correspond.

Figures 1 0 and 1 1 show a section of the conveying member 103, 203 from the region of the conveying section 102, 202. The conveying member 103, 203 is formed as a modular belt chain, which comprises a plurality of over module axes 105. 205 interconnected modular belt members 104, 204 , The conveying member 103, 203 contains contact elements 106, 206, which form together with engagement elements 1 15, 215 on the drive member 1 1 3. 213 a drive engagement.

The drive device 1 1 0, 210 is designed as an intermediate drive The drive device 1 10. 21 0 contains two, transversely to the conveying direction F and in conveying direction F spaced from each other arranged deflection axes 1 12a, 1 12b; 212a. 212b. One of the deflection axes 1 12b, 212b is driven by a drive motor 1 1 1, 21 1. However, it is also the other deflection axis 1 12a, 212a or both deflection axes 1 12a, 1 12b; 212a, 212b each be driven by a drive motor.

The drive device 1 1 0, 210 further includes a about the two deflection axes 1 12a, 1 1 2b; 212a, 212b circumferentially guided drive member 1 13, 213. The drive member 1 13, 213 includes a drive body 1 14, 214, via which the drive member 1 13, 213 is guided circumferentially. The design of the drive body 1 14, 214 is shown only schematically in the figures. The drive body 1 14, 214 can z. B. be a link chain or a band. The drive body 114, 214 forms a drive section 118, 218 for the conveying member 103, 203.

On the outer circumference of the drive body 1 14, 214 spaced apart hook-like engagement elements 1 15, 215 are arranged. The engagement elements 1 15, 215 are each attached via a pivot axis 1 16, 216 on the drive body 1 14, 214. The engagement elements 115, 215 further include a downstream in the direction of movement of the pivot axis 1 16, 216 support portion 120, 220. The engagement elements 1 15, 215 further includes for forming an engagement with a contact elements 106, 206 each have a recess 121, 221st

In the region of the drive section 1 1 8, 218, a guide rail 1 17, 217 is arranged. The engagement elements 1 15, 215, as described in more detail below, by means of the support portion 120, 220 on the guide rail 1 17, 217 slidably guided.

Furthermore, the engagement elements 1 15, 215 each have a recess 121, 221 for forming an engagement with contact elements 106, 206 on the conveyor member 103, 203. The engagement and contact elements 1 15, 215; 106, 206 are each formed and arranged in the drive section 1 18, 218 relative to each other, that the engagement elements 1 15, 215, the contact elements 106, 206 to the conveying member 103, 203 out over. The engagement elements 1 1 5, 215 engage over the contact elements 106, 206 in such a way that they do not allow an evasive movement of the conveying member 103, 203 upwards.

The pivotable mounting of the engagement elements 1 15, 215 on the drive body serves to pivot the engagement elements 1 15, 215 for taking the contact element 106, 206 cross-position to the contact element 106, 206 toward. The pivot position is determined by the guide of the downstream support section 120, 220 through the guide rail 1 17, 217. Thus, the support portion 120, 220 of the engagement element at the end of the deflection of the return-side section 1 19, 219 in the örderseitigen drive section 1 18, 21 8 forms a guide contact with the guide rail 1 17, 217. The guide rail 1 17, 217 has at the beginning of the guide contact in the deflection leading into curvature. The curvature along which the support section 120, 220 follows causes the engagement element 1 15, 21 5 to pivot toward the contact element 106, 206. Following the curved portion of the guide rail 1 17, 217 is followed by a rectilinear guide portion, along which the moving support portion 120. 220 follows. This ensures that the engagement element 1 15, 21 5 in the drive section 1 18, 21 8 remains in the engaged position and z. B. does not swing out of this again.

The guide rail 1 1 7, 217 is further designed so that the guide contact between the guide rail 1 17 217 and support portion 120, 220 before the entry of the engaging element 1 1 5, 21 5 in the deflection of the conveyor-side drive section 1 18, 21 8 in the return-side section 1 19, 21 9 ends. The unguided now before their deflection engagement elements 1 15, 215 tilt before entering the deflection passive, due to gravity, to the pivot axis against its direction of movement backwards. As a result, the attack on the contact element 106, 206 is canceled. However, it can also be provided that the tilting movement is actively triggered by the guide rail 1 17, 217 through a guide extending to the deflection.

This process is important because the engagement elements 1 15, 215 may no longer be in an engaged position with the contact element 106, 206 when entering the deflection. Otherwise, the engagement element would 1 1 5. 215 on the contact element 106, 206 and consequently on the conveying member 103, 203 exert a pulling force downwards.

In the embodiment according to FIG. 10, the contact elements 106 are now formed by the link axes 105 of the conveyor element 103 present as a modular belt chain. The hook-like engagement elements 1 15 form a recess 121 which is concave in cross-section and which is complementary to the link axis 105 which is round in cross-section. In the embodiment according to FIG. 11, the contact elements 206 are formed by hook-like elements which are arranged between the link axes 205 of the conveyor element 203 present as a modular belt chain.

The openings of the hook-like engagement elements 215 and the hook-like contact elements 206 are facing each other in the drive section 218.
