Description

"with belt conveyors

The invention "relates to a device for securing ▼ on openings on the conveyor inlet or outlet between the peripheral area close to the supporting frame of a deflection "or feed or gate roller or roller or Guide and / or pressure roller or roller for the Conveyor means of a belt conveyor, which is preferably in single or multiple belt or - aiemenbauart or as Plate or hinged belt conveyor is carried out, and the rolling Ti zw. Rollennafaea front end of the support frame the same and / or the support piece of the storage device for this roller (s) ″ or roller (s) against the risk of accidents by unintentional or unauthorized intervention in such an opening.

It is a known fact that such openings occur at Belt conveyors of the type described are a dreaded source of danger represent that fingers or parts of clothing get into them during the conveyor operation and could be drawn in between the conveyor and the relevant roller or roller, which experience has shown Can lead to serious accidents, one of which bruising of the limbs is still considered to be of lesser severity are to be addressed. In addition, such openings offer both in the area of conveyors working in one plane both the conveyed goods loading station and the conveyed goods unloading station are present, regardless of whether the drive via the feed roller or roller set or the output roller or roller set or via a separate set of drive rollers or rollers arranged between the two takes place, and in the case of angled conveyor belts in addition to these positions also in the areas on the funding start-up side and on the funding-flow side from Deflection roller or roller set or from the hold-down roller or roller set, in all cases both in the area of the upper run as well as the lower run of the conveyor, undesirable opportunities for dirt or foreign bodies to fall in or be introduced into the Inside the support frame of the belt conveyor, where this creates the risk of malfunctions and / or impairments the hygiene is conditioned and corresponding maintenance and cleaning measures with the corresponding feared Operating idle times after relatively short ones Operating intervals become necessary. So it is highly desirable to use simple and inexpensive belt conveyors and if necessary also by means of retrofitting Means that can be brought into effect quickly and easily remedy these abuses and the belt conveyor against dangerous ones Entrainment of limbs or items of clothing as well as against unwanted penetration of dirt or Secure foreign bodies at the openings described

can.

This is achieved in a surprisingly easier and more economical manner Way according to the invention by a vulnerable gap between the circumferential area of roller "or a roller near the supporting frame and roller or the run-off edge of the support frame close to the roller for the conveying means or its end face close to the roller or roller from the support frame side in the direction of the normal to the conveyed-goods-side surface of the conveyor Central longitudinal plane of the belt conveyor at least "up to." a clearance for the upper and / or the lower run of the conveying means granting a distance to this bridging covering device.

It can be subordinate to a further developing the invention According to the invention, the cover device in each case at least one in the gap endangered access between each side of the supporting frame and the associated side edge of the upper and / or lower run of the conveyor have a wing-like protruding cover member. This can be preferred over the one described Access-endangered space up to the assigned side edge of the upper and / or lower run of the conveying means and furthermore preferably the associated lower run of the conveying means overlap, with the or at least one of the cover member (s) also preferably the associated upper run of the Funding across and / or the or at least one of the A "bdeck member (s) the associated lower run of the Funding can be arranged over and / or under.

Characterizes another proven embodiment of the invention characterized in that the covering device each has at least one clear space between

"Spanning both support frame sides and the upper run of the funding under-reaching and / or at least one spanning the clear space between the two support frame sides and the lower run of the conveyor having under and / or overlapping cover member. Regardless of whether it is the The upper or lower run of the conveyor is, with reaching under always means that the cover member on the side of the conveyor that is remote from the conveyed material or on the inner side lies, while overlapping means that the cover member is conveyed material side from the conveyor or extends on the outside thereof.

Depending on the construction of the belt conveyor, an access vessel can be used The opening of the type described will occur on one or both sides of the support frame and will then by means of a cover member according to the invention or several of the same secured, this for both the task and the discharge end of the belt conveyor as well as for the inlet and / or the outlet area one optionally arranged between the two separate drive station and also for the inlet and / or outlet area of the guide device and / or the hold-down device at the kink of a kink belt design applies. It should also be emphasized that that the invention disregards the type of use described above for securing access-endangered Openings both in the area of the upper run or the lower run of the conveyor alone or but both sides can be used at the same time.

Basically, according to the conception of the invention, it is unimportant what height spacing the or the Cover member (s) have to the associated strand of the conveyor, but there is an embodiment of the invention according to a subordinate idea of the invention especially

/ I * Il M It •

"proven, according to which the or at least one of the cover member (s) as a guide device for the supply or removal of the upper or lower strand of the conveying device to the or the roller (s) or roller (s) is formed. Here can preferably the cover member designed as a guide device on the inside of the support frame or on the outside of the support frame of the assigned upper or lower run of the conveying means its surface remote from the conveyed goods, be arranged as a support or its surface on the conveyed goods side serving as a plant. In these cases it will namely, each cover member is also advantageously used with a further function in that it according to its surface contouring and in particular its arrangement in addition to its safety function is also used for the openings adjacent or at risk of access delimiting side areas of the relevant strand of the To serve funding as a support and guide, so that even greater lengths of such between the support frame and Conveying side area of existing openings in the conveying direction or the longitudinal direction of the belt conveyor secured and at the same time the corresponding length range of the Funding endeavors against undesired or, Support can be offered to secure excessive sagging. This is particularly beneficial then off when it comes to longer lengths of the conveyor belt in the conveying direction that do not have one Utilization of the cover member or the cover members according to the invention as a guide device for the relevant Funding center often an unacceptably high operating load due to excessively large free Would be exposed to sagging length.

Furthermore, it has proven to be particularly advantageous if according to another subordinate inventive concept let cover means at least one pair of itself

In further appropriate training, this or at least

one of the cover member (s) can be arranged fixed to the support frame. |

For both original equipment and aftermarket purposes I An existing belt conveyor can also be recommended,

if in further inventive training the or I

at least one of the cover member (s) on the support frame releasably ';

is fixed. 1

Basically it is according to the conception of the invention ξ

even then it is irrelevant whether the cover member (s) j

are held on the support frame of the belt conveyor if with f

a change in the length of the opening to be secured in Direction of conveyance is to be expected, as is the case, for example, in the course of changing the axial spacing of the "two deflection rollers or -rolls or. -roll sets of the conveyor this can be the case when the tensioning station is actuated, because the cover member (s) can according to the invention in the conveying direction with respect to the support frame adjustable to be held on this. However, an implementation according to an alternative subordinate has proven itself The inventive idea particularly proven, according to which the cover means at least one pair of itself of opposing! Prague pieces of a storage device for one or more coaxial roller (s) or ßolle (n) forth in the direction of the surface of the upper and / or lower run of the conveying means facing the conveyed material side normal central longitudinal plane of the belt conveyor extending Has cover members.

In this case, in an expedient further development of this subordinate inventive concept, in particular "in the case of explanations with support pieces of the storage device which can be changed in position relative to the support frame in the longitudinal direction of the same for the roller (s) or roller (s) the or at least one of the cover member (s) is fixed to the support piece and thereby preferably be designed in one piece with the support piece. On the other hand, however, it has been the case with original equipment as well as for upgrading purposes have proven to be particularly useful if the or at least one of the Cover member (s) on the associated support piece of the storage device for the roller (s) or cone (s) releasably fixed is.

In this context it should be noted that also. Embodiments of the invention can be useful ^ at which jointly use one or more cover member (s) fixed to the supporting frame and fixed to the supporting piece,

which then together "contribute to the security task according to the invention and possibly at the same time also the Trumabs tut eduction * In all versions with releasably fixed or fixed cover member (s), it can prove to be advantageous if in further inventive training the cover member or members (it) is or are fixed on the outside or on the inside of the associated longitudinal spar or side web of the support frame or the associated support piece of the storage device for the roller (s) or roller (s) manufacture of the cover members and / or claims of the same with respect to the operation of the belt conveyor and hygiene as well as the nature of the formation, and optionally de _B terminal thereof to upstream and / or downstream equipment of a conveyor line as well as in terms of simplicity and speed of assembly and disassembly decisive nd be.

Furthermore, it has proven particularly useful if, according to another subordinate inventive concept for embodiments, in which at the same time cover members are provided for both the upper run and the lower run of the conveyor are attached to a longitudinal spar of the support frame or a support piece of the storage device for the roller (s) or role (s) assigned

equidistant from

the adjacent longitudinal edge of the longitudinal spar or support piece, preferably in alignment therewith are. It has also been shown to be advantageous from the same point of view if in such designs with the upper and lower run of the conveying means protected according to the invention, which is a longitudinal spar of the support- frame or a support piece of the storage device for the roller (s) or roller (s) assigned cover members for the upper and lower run of the conveyor with the same

Distance from the beyond the roller or Bollenaöhse located front edge of the longitudinal spar or support piece are arranged. With both measures on their own and even more so with their interaction, let yourself be calibrated in the sense of the task underlying the invention, further rationalizations of storage for the Creation of belt conveyors of different designs and sizes required items and achieve their assembly insofar as in such cases both longitudinal spars for the creation of the support frame as well as its entire width forming profile pieces as well as the support pieces for the creation of the storage device of the required roller (s) or. Role (s) no longer need to be kept in stock in right and left versions, but one gets by with a single version of these items.

In the interest of using existing longitudinal spars and / or support pieces that are more conventional for designs of belt conveyors Serve kind, it has both for the initial production of belt conveyors according to the invention as well for the conversion or retrofitting of conventional designs to the invention proved to be advantageous if according to Another subordinate inventive concept that or at least one of the cover member (s) is preferably used as an angle piece is formed from sheet metal or plastic, which with its to a to the central longitudinal plane of the belt conveyor parallel plane of the adjacent longitudinal spar. and des Side web of the support frame or the adjacent support piece of the storage device for the roller (s) or Roll (s) parallel a leg on this longitudinal spar or side web or this iragstück is fixed. Advantageously, this definition of the elbow can be done so that it can be used as a cover and optionally also guide legs that do not function on the longitudinal

holm "or side web of the support frame or on the support piece the storage device fixed free leg runs parallel to the longitudinal axis of this longitudinal spar or side web or support piece. Basically is Although such a design and arrangement is by no means necessary, since the fuse cover according to the invention and possibly also funding support at the same time for the purpose of guiding the same forming angle pieces with opposite to the longitudinal axis of the spar inclined free leg can be in the working position, especially in some designs of belt conveyors the main course of the strand in question runs in a different plane than the corresponding tangential plane to the roller (s) or pulley (s) deflecting the relevant strand of the conveyor. An execution and arrangement However, this angle piece with a free leg parallel to the longitudinal axis also offers here as well as in the previously described subordinate concept of the invention in terms of the profile height of the longitudinal spars or side bars of the support frame symmetrical design

Formation and arrangement of the cover members and also the symmetry of the training and arrangement of cover members supported by a support piece of the storage device for simultaneously the upper and lower run of the conveyor with regard to the outer edge of the support piece remote from the supporting frame, the advantage of doing without right and left versions and instead with a single one Execution to get along.

For certain types of belt conveyors, namely in particular those in which, for reasons of a special lightweight construction, additional stiffening of the overall structure of both the support frame rollers and the storage device for the roller (s) or roller (s) should be omitted, » has it proven to be useful if after a alternative subordinate invention ideas that or '

at least one of the cover member (s) as a U or G profile is preferably formed from sheet metal or plastic, each with its to one to the longitudinal plane of the shaker Belt conveyor parallel plane of the "adjacent longitudinal spar or side web of the support frame or of the "adjacent support piece of the storage device for the roller (s) or Bolle (n) parallel side bars on this longitudinal spar or side bar or support piece is set. Here, too, the cover member design can be preferred and -Arrangement be made so that it is in a working position in which its bridge-like Central web parallel to the longitudinal axis of the longitudinal strut or side web or support piece holding it runs. It can be seen that while maintaining the advantages already described, the as Elbows formed cover members by the design of the cover member after this subordinate Thoughts of the invention also one for improving the bending and torsional stiffness of the entire frame structure of the belt conveyor not infrequently achieved desired bridge-like stiffening of the same can be.

In particular, but by no means exclusively, for retrofitting tasks there may be a requirement that no machining work be done on an already installed Belt conveyor system should or may be carried out, which, however, is to be equipped with the invention. In such cases there may be difficulties with the support of the cover member or the cover members on the support frame or on a support piece of the storage device. Here an execution according to helpful to another subordinate inventive idea be, according to which the or at least one of the cover (s) relative to the axis of the roller (s) or Bolle (n) is supported. This axis is mostly in place available with sufficient width as a support,

However, it is generally not used as such "because experts have an additional one for this Rolling bearings considered necessary to have a grinding with corresponding wear and undesirable To avoid noise pollution. Experience has shown, however, that this is by no means required is, you can also with a simple support of the "Ab.deek link concerned on the roller" or Bollsatz-Axis can get by and at most an inexpensive lining of the support point with plastic material, such as tetrafluoroethylene, can be sufficient to effectively eliminate all undesirable abuses.

Regardless of whether only from the support frame or support piece into the space between the two opposing longitudinal bars or side bars of the support frame or support pieces of the storage device protruding cover members or only one same on one side of the relevant Fördermi fcteltrums or a cover member construction that spans this space in the manner of a bridge for use comes, it has proven to be recommended for many applications, if according to a further subordinate Idea of the invention, which relates to both the support frame fixed and the support piece fixed cover members relates, the cover member (s) for the upper run and / or the cover member (s) for the lower run of the funding a different from his or her on Farthest from the roller or roller axis of the fastening point in the longitudinal direction of the belt conveyor approximately like a flag in the space between the opposing longitudinal spars or side bars from the support frame or support pieces of the storage device for the roller (s) or roller (s) extending into it Has or have tongue. In this case, the flag-like tongue can develop in an expedient way

'be, that is to say, the Ahdeck member (s) according to the invention Is supported on the support frame or by support pieces of the roller or roller storage device j or are opposite the front edge of the support frame

do not undergo any shifts, as is often the case, for example, with drive stations provided on the front side of the frame the! "all. With such designs, such flag-like cover member extensions can then recommend, if the greatest possible coverage length

is desired in Eahmenlängsrichtung or conveying direction, for a fastening of a cover member after Invention of a corresponding length above this on the associated longitudinal spar or side web of the support frame or Support piece of the storage device but no possibility is given, for example because certain sub-areas of this total length of such a cover

has, "to over the adjacent front edge of the support frame or a possibly provided Schlür- or cover plate of the same extending length. Here, regardless of whether the Sioherungscover according to the invention as free on both sides in the tree between the two {drag pieces of the storage device protruding cover members or designed as this bridge-like overlapping construction is to be ensured in a very simple manner that regardless of the type and size of the respective displacement movement the roller or roller axis opposite the front edge of the HJragrahmens for example in the course the actuation of a tensioning station .tür the conveyor to which this storage station 'belongs, each in the area of which is at risk of access opening to the Interior space between the two conveyor belts reliably through corresponding constantly on the whole Length of this opening effective cover remains secured, and this without any impairment any desired guidance or support function for the assigned funding section in its side edge area or, if so, too desired, across its entire width.

For embodiments of the invention with releasably fixed or fixed cover member (s), it has also been found for reasons of rationalization of the production and assembly and due to the knowledge that opposite Cover members which can be changed relative to the load-bearing component are possible, but in most cases by no means are required to perform the corresponding safety and, if necessary, support and / or control function to take over, proved to be particularly expedient if according to another subordinate invention the cover member (s) opposite the associated longitudinal spar or side web of the support frame or the tensile

arranged support piece of the storage device for the roller (s) or roller (s) relative division unchangeable is or are determined on this. In this case, the cover member (s) can advantageously .jeweils be set by means of at least one screw element. On the other hand, however, it looks like for most of them Applications are even more expedient because they can be produced and assembled or dismantled more easily and economically proven when the or the cover (s) each by means of a tragrahaenferaen and / or a near the support frame or by means of two on the support frame or the side close to the supporting frame or on both sides of the roller (s) or should (s) arranged or arranged Plug connection (s) each consisting of a longitudinal spar or plug-in pin fixed to the side web or support piece and a receiving socket fixed to the cover member for this or a plug-in spigot that is fixed to the cover member and a mounting that is fixed to the longitudinal strut or side web or support piece © - * socket for this is or are. This design makes it possible to dispense with, even then, if these are commercially available, relatively expensive screw elements or the introduction of threaded holes through the possibility of using simple round bar steel profiles in cooperation with for example, during the bending deformations of the frame-forming parts in these punching holes or but simple holes.

Purely specific cases of application has changed when executing the Invention with releasably fixed or fixed cover member (s), however, a cover member holder in particular proven in which the cover member (s) relative to the associated longitudinal spar or side web of the support frame or the associated support piece of the storage device for the roller (s) or ball (s) pivotally attached to this is or are. Here can

"or the cover member (s) can advantageously each by means of one on the support frame remote or on the side of the roller (s) or roller (s) close to the supporting frame arranged plug connection from a longitudinal spar «or side bar or support piece-fixed plug-in pin and a Cover member-fixed receiving socket for this or one plug-in pin fixed to the cover member and a lengthwise spar or be fixed for this receptacle that is fixed to the side web or load-bearing knit. Here, too, they already arise described advantages of such connectors. The pivoting articulation of the cover member or the cover members not infrequently opens a special constructive freedom of movement and can be a considerable relief contribute to the assembly and / or disassembly of the same, for example, for inspection or maintenance purposes and also otherwise facilitate handling.

Furthermore, it can expediently be provided that the or the cover member (s) each at his or her tail The end to be designated, remote from the roller or roller, is supported in a fixed manner on the support frame for sliding movement. are. Furthermore, the cover member (s) can, in an advantageous further development, be a cranked one have the end remote from the roller or roller. Regardless of the type, where and how the cover member is supported or the cover members takes place according to the invention, this or these can according to another development the invention an approximately Z-shaped opposite have his or her roller or roller near end angled roller or roller remote end. Furthermore, it can be advantageous if the cover member (s) is supported on the side rail or side web side by means of a sliding guide device or are. A particularly simple and yet sufficiently reliable one Execution is characterized in that

Cover member CerJran is or are attached to these longitudinal bars or side bars or supporting pieces. The cover member (s) can be fixed to the associated support rod by welding, gluing, screwing, clamping or pinning, with its or their roller or roller remote connection area (s) with respect to this fixing point ) is or are crimped around this support rod. Obviously, such an embodiment of the invention can be produced particularly easily and practically at any place of use of a belt conveyor without the need for larger or mechanical and correspondingly expensive tool equipment and can be brought into working position very easily.

It is also recommended, especially for special cases if with another advancement of the invention the covering device for changing the size of the

Movement play for the upper and / or lower run of the Funding is formed granting distance. In this case, the cover device can preferably have at least one effective width in sight of the conveyed-side surface of the conveying means normal Have the central longitudinal plane of the belt conveyor adjustable cover member. This also makes it possible in the interests of the rationalization aimed at by the invention, prefabricate and open cover members To be able to keep stocks for different belt conveyor designs or sizes or types should be equally usable.

Another purposeful one aims in the same direction Port formation of the invention, according to which the cover device for changing the size of their distance to associated roller or roller arrangement is formed. The or at least one can expediently the cover member (s) is displaceable for changing its distance from the associated roller or roller arrangement and can be fixed in the desired working position on the associated longitudinal spar (s) or side bar (s) of the support frame or on the assigned support piece (s) of the storage device for the roller (s) or role (s) be supported.

'In Fig. 1 is also an alternative to the cover device fixed to the support piece described above 22 other embodiment which can be used is shown,

which is designated as a whole with 32 and is special suitable for retrofitting existing belt conveyors with the invention. This covering device 32 consists of a pair of cover angles, one of which is shown in FIG. Each of the same is with its side web 31 on the side web 4 of the longitudinal beam profile 5 of the support frame 3 by means of threaded holes in this side web 31 of the cover bracket 32 or the side web 4 of the longitudinal member profile 5 is provided Threaded holes engaging and corresponding complementarily arranged through holes in each other web penetrating or in a mutually complementary arrangement in both abutting one another webs 31 »4 to be connected to one another are provided Through holes of penetrating screw elements are defined, which are only indicated by their dash-dotted center lines and marked with 47 » As shown, the holes can be in at least one of the mentioned webs, for example in the side web 4 of the longitudinal spar profile 5 »be designed as elongated holes, which are designated by 6 in FIG. 1.

New. Such a design is obviously also suitable Preferred for retrofitting purposes on conventional designs of belt conveyors.

This embodiment according to FIG. 2 corresponds essentially to that according to FIG. 1, but only as an example the left support piece 13 of the roller "or Bollen storage device the same corresponding \ version with a receiving hole designated here with 56 for the Rolls or Bollensat ^ axis is shown, however the support piece 53 reproduced here would instead also have a slot in the same way with a recording can be equipped, as is the case with the support piece 23 according to FIG. 1 and described above for this is. The embodiment according to FIG. 2 differs from the embodiments described so far by the fact that the support piece shown here 23 cover members 22a and 22b both for the back and for the Has a return run of the conveyor 29. These approximately ear-shaped cover elements 22a, 22b are in the the same way as is shown in the case of the cover elements 22 of the support pieces 13 and 23 according to FIG. 1, with their outer surface aligned with the upper and lower end face of the support piece 53. she but could also be arranged at a distance from the respectively adjacent end face of the support piece 53 be, but this distance should preferably be the same in order to use such a support piece design to ensure for both support frame sides and thus right and left versions for to avoid the bearing support pieces. The aligned version shown in Fig. 2 is for bilateral Use suitable and intended.

Compared to the üragstückausführungia 13 and 23 according to Fig.

1, the support piece 53 according to FIG. 2 also differs in that its central web 54 does not extend over the Near the support frame end face of the approximately ear-shaped cover members 22a, 22b extends away. The reason for this is that the execution according to! "Fig. 2 for the associated front end of the support frame 3 "or of its longitudinal spar profile 5 from the outside overlapping or on whose inside fixable fixing is provided on this. For this reason, it has instead of a fixing slot 15 »which, by the way, could have been used here as well, two rows of elongated holes 55, through which screw elements are to be inserted, either in a corresponding arrangement on Engage associated support frame profile provided threaded holes or provided in a corresponding arrangement Reach through through holes and by means of which the relevant support piece 53 on the support frame 3 of your choice the suitable working position can be fixed by shifting in the longitudinal direction of these elongated holes 55 in is. Corresponding re-tensioning measures or adjustment work can also be carried out extremely easily will. It should be emphasized, however, that an embodiment according to FIG. 2 also includes the end face on the support frame side of the cover members 22a, 22b extending away guide strips in the manner of the guide strips 14 and 24, respectively the support pieces 13 and 23 according to FIG. 1 can be equipped. Do this if it seems desirable should that the length of these guide strips is not chosen to be particularly large, either the cover elements 22a and / or 22b corresponding engagement slots for the side webs 4 of C-shaped longitudinal spar profiles 5 of the support frame 3 or these side webs corresponding engagement slots for the cover elements 22a and / or 22b to have a sufficient size of the possible relative displacement path of support

to ensure piece and support frame. The same applies to the rest of the support pieces 13 and / or 23 according to FIG Fig. 1 and the respective adjacent front ends of the longitudinal spar profiles 5 · Otherwise, in the front End areas of the side webs 4 can also be dislodged or removed to a corresponding length.

In the embodiment shown in Fig. 3 is a cover device in the form of a Cover bracket 63 with cover members 22a and 22b, the. extend away from a central web 64 in the same way as described above for the exemplary embodiment according to FIG. This cover bracket 63, which can preferably be designed as a stamped sheet metal part in order to be particularly economical Lightweight component that is easy and quick to manufacture and can be easily and quickly brought into working position to offer, has in a similar arrangement, as already described for the embodiment according to FIG. 2, two legs elongated holes 65 on. Obviously is suitable this version also especially for retrofitting purposes on existing ones. Conventional belt conveyors, by removing the angle piece 63 from the outside in the areas at risk of access assigned frame profile or else. Support piece across or from the inside of the frame can be set on this so that its approximately ear-like cover member 22a the access-endangered Gap 41 in the area of the upper run 29a of the conveying means 29 and its cover member 22b a corresponding one Access-endangered intermediate space in the area of the lower run 29b covers the same protectively. Here, too, could basically the cover members 22a and / or 22b with extending over the front edge of the central web 64 Extension tongues are formed, but this would result

Otherwise, however, it should be emphasized that the guide strips 44 of the inner piece 43 and / or the guide strips 34 of the outer piece 33 of the buckling fitting in the same way the end face on the support frame side of the associated cover member 22 can have outstanding length, as is the case with the bearing support pieces 13 and 23 shown in FIG. 1 and for these as well as for the embodiment according to FIG. 2 above is described.

Apart from the different design options for the support frame structure, FIG. 6 shows two other preferred embodiments of cover devices according to the invention. So is in the lower one Half of Fig. 6, a cover member 42 is shown, which can be formed as an elbow to an open and corresponding access-endangered space 41 between Frame side area, like this one through the hollow profile 8 formed longitudinal spar, and the end face or side edge of the conveyor belt run 29a against to cover unauthorized or unintentional access or drawing in of clothing or the like securely. Included

it should be noted that "for example to the right of the cover member 42 shown is the storage device for a deflection or feed or delivery roller or a corresponding roller set is located without being shown eein by placing this either directly in the end of the supporting frame or is rotatably supported with the interposition of corresponding support pieces of a storage device, which are also not shown for reasons of clarity and are designed in any way can be, and that calibrated on the left. Side to the cover member 42 then a cover of the space 40 between the two opposite one another. Support frame sides or Länssholmprofilen 3 in the form of a, although not shown, the relevant strand of the conveyor 29, here the fragmentary dbertrum 29a, reaching under bridging Sohlür- or support plate is provided between the two opposite Support frame sides or * longitudinal struts 8 is attached. The angular Cover member 42 is by means of two cover pins 11a, into the corresponding mounting holes in the assigned longitudinal spar profile 8 intervene, which due to the execution of the same as a hollow profile, expediently with a socket 10 can be lined, detachably held on the support frame 3. Its width is chosen so that its after angled web pointing downwards (shown in the lower half of the figure by a dashed line) in one for ύη-filled or unintentional access safe distance 39 to the end face or sand edge of the relevant. Funding strand, here e.g. the upper strand 29a of the funding strand 29, remains, which, however, ensures a sufficient amount of movement.

The Abdeok member 42a by a corresponding arranged and supported by the two plug pins 41 a fixed to the frame, it is T-profile or else be formed by an angle profile, which is in the manner of Cover bracket 32 according to Hg. 1 held fixed to the support frame is * Ee can also be one with its interior after U-profile arranged open at the bottom find use, and this is true both of the one designated by 42 as well in the version designated 42a. In both cases it would then be preferable to only use one side flange to pierce the U-Profila in order to be able to insert a plug-in pin 11a through this, the on the inside of the opposite side web of this profile and there and / or on the inside « side of the hole through which it penetrates by welding, for example, by means of fewer spot welds, could be determined

In the top half of Pig. Figure 6 illustrates another preferred embodiment of the invention. True is Here the support frame is shown in the form of a piece of a longitudinal spar 7 designed as a solid part, but could readily the support frame 3 also as a hollow profile 8, such as in the lower half of FIG. 6, or as O-profile, as in Fig. 1, or in the form of another profile not shown, for example one in the transverse direction one-piece C- or U-profile with the supporting frame sides forming side bars. In any case, there is one at a suitable point to the longitudinal plane of the frame m approximately parallel web or flange

the support frame structure a receiving "or plug hole 9 is provided for the plug-in pin 11a of a support rod 11, with which a cover member 12, for example by UmbördeJung, as this" is shown for example in FIG. 5, and requires. od derlichenfalls by corresponding fixing means of _Si gluing, squeezing, welding, soldering. b like. is connected. This support rod extends the entire space 40 between the two opposite support frame sides or longitudinal spars 7 bridging over practically the entire conveyor width, and its plug-in pins 11a are in the support frame profile-side receiving holes 9, which in the case of a hollow profile design, as shown in the lower half of FIG. 6 , can expediently be lined with a socket 11a, inserted. The support rod 11 carries a one-piece cover member 12 that spans the entire space 40 mentioned except for a play 39 'shown in the upper half of FIG. 6 or, in a corresponding arrangement, narrower cover members fixed close to the support frame. The peculiarity of this embodiment is that here the cover member 12 is not held in a position as described or predetermined by other measures, but has the degree of freedom to be able to pivot relative to the component carrying it. In addition to any manufacturing and assembly-related advantages that may be present, this can also result in structural simplifications and operational simplifications. It can be seen that such a design only needs to be inserted into a hole in a grid arrangement in the support arm side wall with the plug-in pins 11a of its support rod 11, which is usually present in conventional belt conveyors, without requiring further labor-intensive measures if care is taken that the length of its cover member 12th

is so large that this is made up of one of two opposite one another Support frame longitudinal spars 5 "or 7" or 8 with each other connecting Qjuertraverse 25 is supported so that its tail end formed by a flag-like extension do not fall down and conflict with the lower run 29b of the conveyor 29 may come.

In the upper half of FIG. 6 it is indicated by solid lines a that the cover member 12, which is by no means here to serve as a support for the adjacent run of the conveying means 29j, for example its upper run 29a needs, but this can be done with an appropriate design, one only in the central region of the space 40 between both support frame sides or longitudinal struts 5 or 7 or 8 located in the direction of the adjacent rolls or. Roller assembly extending away from tail portion 12b having. However, a dash-dotted line also indicates that the between this and the through A solid line delimiting the central area of the cover member 12 is by no means notched out the flag area 12a or needs to be excluded, rather the cover member 12 remains unchanged over its entire length Width can extend.

While in Fig. 6 is shown in principle that and how such cover members 42 and 12 on the support frame side on a fixed remaining part of the support frame 3 »for example a longitudinal spar profile 5 or 7 or 8 of the same, can be supported, Fig. 5> shows that in the same This can also be done by holding it on a support piece or a pair of support pieces of a roller or roller bearing is possible. For example, Xn Fig. 5 is one Support rod 11 shown in a support piece 13 of a bearing eye device for a roller 20 with an axis or Shaft 21 relatively pivotable near the upper run 29a of the Conveyor 29 is mounted and a cover member 12c

which is suitably cranked to a tail portion 12c of sufficient length for approaching a Qa traverse 25 ". But it is the same also one on the support piece 13 below the strand. pivotably fixed support rod 11, which has a cover member 12 carries, the tail part 12d of which is angled approximately in a Z-shape and has a free end region of sufficient length, by a cross member 25, shown in the Embodiment of the same cross member, which also the upper run-near cover member 12 with the tail end 12c braces to be worn. It can be seen that in this version, for the rest of the time with regard to Art The same applies to the definition, as already described above for the two embodiments according to FIG. 6, the Cover Glioder 12, as they are supported by a support piece 13 of a Shaft or B-sleeve bearing devices are carried, each possible offset movement of the roller or roller axis 21 relative to the trailing or leading edge of the Support frame 3 forming front edge 38, which ^ properly the inside or outside of the free leg of the support bracket 9 according to FIG. 5 may correspond, in sighting of the double arrow A, as could be the case, for example, in the course of adjustment or re-tensioning measures, follow without releasing in any way the gap 41 to be secured, since the Cover members 12 have sufficient tail length supported by the cross member (s) 25, with which they are slidably guided and supported on the cross member in question. Without this would be shown, but is also a holder of a cover member 42 described above in the manner of the lower Half of Fig * 6 also with support of the same by a relative to the support frame 3 displaceable Support piece of a roller or ball bearing device is easily possible. Does this still know it in

Tongues extending in the longitudinal direction approximately in the manner of the extension tongue 50a of the cover bracket 32 according to FIG. run-off edge for the associated Fördermitteltrum independently at the same f-binding complete covers the access vulnerable interspace 41 can be realized.

Finally, it should be pointed out that although not f- for the upper run 29a of the conveyor / means 29, which is loaded on its outside with conveyed material, the cover device 2 or 12 or 22 for the lower run 29b of the conveyor 29 or 32 or 42 or 42a can be arranged so that it secures the access-endangered space either on the outside or the inside or possibly also over both sides, while for the upper run 29a of the conveyor 29 only a κ fuse on it Subpage can come into question. For (embodiments of the invention in which, for the purpose of avoiding right-hand and left-hand designs of individual components, such as, for example, drag pieces of a roller or roller bearing device that hold the cover member, avoiding designs of these components, practically only such a design can come into question, in which for both the upper and lower run 29a or 9b of the conveyor means 29, the associated cover member is arranged so that it engages under the latter, ie is located on the inside thereof.

For the rest, the invention, although it has only been illustrated and explained with the aid of a few preferred exemplary embodiments, is not restricted to these, but rather diverse possibilities are open to the person skilled in the art
