Description

The invention relates to a support profile for a sliver creel. It also relates to a gate equipped with it and an arrangement with a spinning preparation machine that can be formed with such a gate.

Gate arrangements themselves are known and are used to forward sliver from storage containers such as cans via a guide to a spinning preparation machine, for example in the form of a draw frame. For this purpose, each sliver is removed from an associated can essentially vertically upwards in relation to a floor, deflected via a preferably driven deflection roller at an angle of approximately 90 ° in the direction of the spinning preparation machine and via guide sections parallel to other slivers from other cans arranged in this creel arrangement arranged. These slivers, which are aligned parallel to one another, are then fed to the spinning preparation machine.

US 3,337,923 A , DE 692 17 002 T2 , US 3,305,896 A and DE 11 15 624 B disclose conventional two-row sliver creels.

A gate used for this purpose has a frame that has several feet, to which a continuous support profile is attached at an upper end. The feet are attached to the underside of the support profile facing the floor. For this purpose, there are receiving grooves on the underside of the support profile. These are usually continuous and extend along the longitudinal extent of the support profile. There are corresponding grooves for attaching the feet, drive rollers and other components of the gate T-slot nuts are inserted from one end face of the support profile. The sliding blocks therefore also include corresponding screws and holding parts for the elements to be attached, such as sliver guides and the like. i.e. An enormous number of individual parts are required for assembly, which increases costs and makes assembly itself more difficult.

There are other disadvantages that arise from this type of gate. On the one hand, there is a desire to use storage containers with increasingly larger capacities in order to reduce downtimes, for example on the route due to the need to change cans when a can is empty. Since the height of the gate is limited, particularly due to the necessary accessibility for changing cans, the only solution is to increase the width dimensions of the storage containers. Since these storage containers are usually designed as cans with a circular cross-section, this means that there is a desire to use cans with ever larger diameters. However, this leads to a greater length of the support profile. Due to the aluminum material in such support profiles, lengths of up to around 6 m can be achieved. With longer lengths, the risk of twisting and/or bending increases. In addition, the motor for driving the drive rollers can weigh an enormous amount of up to 20 kg. The motor is attached to one end of the support profile and causes the support profile to tend to twist, especially with the length mentioned of more than 6 m. This affects the functionality of the entire drive including the drive rollers.

In addition, during assembly, the necessary sliding blocks to be attached between the outer two feet must already be inserted into the receiving grooves before these feet can be mounted.

The feet only need to be installed in order to set up the gate. I.e. the other parts must be assembled afterwards. If some sliding blocks are missing after at least the two outer two feet have been attached, these must be pushed laboriously and laboriously from one end face of the support profile through the space between the respective base and support profile towards the assembly site. For example, some kind of rod is necessary. The sliding blocks can tilt in the respective receiving groove. Furthermore, it is necessary that the sliding blocks for the element to be attached are inserted and placed in the exact position relative to one another. This is extremely difficult. To simplify this, spacers could be inserted between the sliding blocks, but this would further increase the number of parts required. This increases costs because additional parts that are not actually required for assembly are necessary to prepare for assembly.

Last but not least, the receiving grooves are open towards the floor. This means that the person concerned always has to work "overhead" during assembly or repair work, which is very laborious and tiring. Apart from that, due to the hanging arrangement of the driven parts on the support profile, many drive parts, such as a drive belt, are open to the sliver storage containers. As a result, abrasion, dust and the like that arise during operation can be deposited on the sliver material, which is disadvantageous for the production chain. In particular, this unnecessarily deteriorates the quality of the possibly already cleaned sliver material.

The object of the invention is to counteract these disadvantages.

This task is solved by the subject matter of claims 1, 9 and 12. Advantageous developments of the invention are specified in the subclaims.

The invention provides a support profile. This has two side walls arranged at a distance from one another and parallel to one another and a bottom section. The bottom section connects the two side walls to one another at their edges, which point in the same direction and run along a longitudinal extent of the support profile. If the bottom section is formed by means of a flat wall, a support profile with a U-shaped cross section is advantageously created. Furthermore, the support profile has a cover section, which now connects the two side walls to one another at their edges facing away from the base section and also extending along the longitudinal extent of the support profile. This creates a support profile with a completely enclosed interior space when viewed in cross section. The two side walls, the cover section and the bottom section completely enclose the said interior of the support profile, at least in sections, as seen in the longitudinal direction of the support profile. Attachments are formed on the base section and are designed to be attached in a stationary manner to a respective base. This means that a gate, essentially consisting of a support profile and feet, can be easily assembled and set up, without any additional parts being attached to it in advance.

First through openings are formed on the two side walls in such a way that, viewed transversely to the longitudinal extent of the support profile and the feet, each first through opening in one side wall is aligned with an associated first through opening in the other, opposite side wall. Corresponding pairs of first through openings are thus formed. By at least one of these pairs of A shaft can rotate freely and is inserted in a stationary manner through the first through openings in the side walls. As a result, their axis of rotation runs along the alignment direction of the two associated first through openings and thus transversely to the longitudinal extent of the support profile. The two through openings thus stabilize the shaft in the support profile. This means that neither slot nuts with screws nor special holding parts are necessary; The bracket takes over the support profile itself. This minimizes the number of necessary parts and thus simplifies assembly. Last but not least, this has a positive effect on costs. And since the shaft is arranged in the interior of the support profile, it can also be mounted from "above", which simplifies installation enormously.

According to the invention, the shaft is rotationally connected to a section which is arranged in the interior of the support profile with a drive means. i.e. The entire drive mechanism can advantageously be accommodated in a housing of the support profile that is completely closed in cross section. This reduces or even prevents the risk of abrasion or other dust from the drive parts being deposited on the sliver material. On at least one outer side of a side wall, which faces away from the other side wall, the respective shaft has a driving section. In cross section, this has a circular outer contour with an outer surface that is designed to take along sliver upon contact when the shaft rotates. This ensures that the sliver is transported across the support profile. In addition, the shaft can be mounted in advance in the support profile, and the driving section can be mounted subsequently, if desired, on it, for example by means of screws. This means that the support profile can be assembled in advance without feet, since there are no protruding parts that could break off or be damaged in any other way when assembling the feet and/or when setting up the gate.

Second through openings can also be formed on the two side walls analogously to the first through openings. i.e. they are aligned with each other in the same direction as the aforementioned first through openings. A first bolt is inserted in a stationary manner through a pair of the second through openings in the side walls. Each first bolt protrudes at least with one end beyond an outside of a side wall on which the driving section of an associated one of the at least one shaft is formed. Each bolt is arranged in front of the associated shaft, viewed in the direction of sliver travel. The respective bolt also includes a projection which is designed to protrude at an acute or right angle to the axis of rotation of the first axis. The projection is additionally freely rotatable on the bolt and is arranged in relation to the associated shaft in such a way that the associated shaft is located with an area in the path of the projection of the associated first bolt when the first bolt rotates about its axis of rotation. i.e. As the projection rotates, it will at some point come into contact with the associated shaft. The projection of the associated first bolt and the driving section of the associated shaft are designed to be electrically conductive to one another, at least in the possible contact area. Both the projection and the electrically conductive area of the associated shaft are electrically coupled to a sensor system. This is designed to detect the presence of electrical contact between the projection and the associated shaft. During operation, sliver would pass between the shaft and the associated projection. If there is a sliver tear or if the associated storage container is empty, no sliver would pass through. At that moment, the shaft and the projection would come into electrical contact with each other, and this could be detected, for example, the gate itself and possibly to temporarily shut down a spinning preparation machine downstream in the direction of sliver travel.

In the case of the aforementioned support profiles, third through openings can also be formed on their two side walls, analogous to the first through openings. A second bolt is fixedly inserted through a pair of these third through openings in the side walls. The bolt protrudes at least with one end beyond an outside of a side wall on which the driving section of an associated one of the at least one shaft is formed. The second bolt is also arranged in front of or behind the associated shaft, viewed in the direction of sliver travel. The protruding end of the bolt has at least one guide. This extends along the longitudinal extent of the support profile and is designed to be open in the direction away from the associated second bolt and away from the base section. This means that the sliver drawn in over the shaft can be aligned with respect to the subsequent spinning preparation machine so that it can optimally enter the spinning preparation machine.

Each of the aforementioned support profiles can include a first profile section. This has two first side wall sections arranged at a distance from one another and parallel to one another and a bottom wall. The bottom wall forms the aforementioned bottom section of the support profile. It also connects the first side wall sections to one another at their edges, which point in the same direction, face away from the cover section and run along the longitudinal extent of the support profile. The support profile further comprises a second profile section. Analogous to the first profile section, this has two second side wall sections arranged at a distance from one another and parallel to one another and a top wall. Analogous to the base wall, this now forms the cover section of the support profile. It also connects the second side wall sections to one another at their edges, which point in the same direction and now face away from the bottom section and run along the longitudinal extent of the support profile. A first and a second side wall section are each fastened to one another and, as a whole, form the aforementioned side walls of the support profile. This creates a box-like assembly composed of two halves, namely the two profile sections. According to the invention, each pair of through openings aligned with one another is formed either in the first or second side wall sections. i.e. During assembly, for example, each shaft is held by a pair of first or second side wall sections.

Each of the aforementioned support profiles can be formed, viewed in the longitudinal extent, by means of several partial segments fastened to one another in pairs. I.e. no single, continuous profile part is required. On the one hand, this makes it possible to adapt the support profile to the desired number of storage containers. On the other hand, it is possible to produce segments with through openings and different lengths. These can be put together in a modular manner and adapted to the respective storage container size, all at comparatively low cost. Due to the standardization of sliver can sizes, this also enables the provision of standardized, partially assembled support profile segments, which only have to be selected according to the respective operating conditions and assembled into a support profile. This reduces manufacturing costs enormously.

According to the invention, each of the aforementioned support profiles further comprises, as a drive means, a motor which, viewed in the longitudinal extent of the support profile, is attached to one end of the support profile. According to the invention is a drive belt provided, which is wrapped around several, preferably all, shafts in such a way that the drive means is able to rotate the wrapped shafts in one and the same direction of rotation. Wrapped around means there is a sufficiently large contact area between the belt and the respective shaft, so that when the belt drives the shaft, it is safely set in rotation. This ensures that the driven shafts rotate and do not stand still unintentionally. Another advantage with regard to the aforementioned sensor system is that a tear in a sliver can stop all shafts at once by only switching off one drive means. This creates a modular unit.

If there are several pairs of first through openings, it is possible according to the invention for a shaft, as described above, to be inserted into each pair of first through openings. A deflection means is preferably provided for all shafts, apart from the shaft that is arranged furthest away from the drive means. Each deflection means is arranged between two shafts arranged immediately adjacent and is accommodated in a freely rotatable manner by means of an associated holder on an inside of the support profile or by means of an associated axis in corresponding receptacles in the side walls. It is further designed and arranged in such a way that the drive belt, coming in the drive direction from an output shaft of the drive means, is deflected by each deflection means and each shaft with respect to the shaft or deflection means arranged immediately in front of it in the drive direction. The drive direction is the direction of movement of the belt along the longitudinal extent of the support profile in the contact area with the respective deflection means or the respective shaft. This ensures that the drive belt comes into safe contact with each shaft to be driven. Without deflection There would be a risk that the drive belt would lose contact with one of the shafts and/or would not be able to exert any force on one of the shafts due to the contact surface being too small. This improves operational safety.

Each of the support profiles equipped with a drive belt can have a sensor system. This is arranged inside the support profile and is therefore protected from external influences such as sliver lint. It is set up to detect if there is a crack in the drive belt, the drive belt is too long so that its driving effect is no longer guaranteed, and / or one of the at least one shaft is not driven or is not driven correctly. This means that there is no need to manually check the drive belt during operation, which simplifies the operation of the gate.

This support profile preferably also has a belt tensioning section which is designed to adjust a tension of the drive belt. The resulting re-tensioning of the drive belt is due to the fact that the drive belt expands in length over time during operation. This increases the service life of the drive belt.

The belt tensioning section is preferably designed to automatically adjust the belt tension. i.e. There is no need to manually check whether the drive belt tension has become too weak, which further reduces the operating effort. In conjunction with the aforementioned sensors, it can also be automatically detected when the drive belt needs to be replaced. This means that a person only has to operate the gate to replace the drive belt, which reduces the operating effort to a minimum.

In the case of the drive means attached to the front of the support profile, this is attached to a holder in such a way that the weight of the drive means and the holder is introduced into an associated one of the feet. I.e. The weight is not absorbed by the support profile but by a corresponding base attached to it. This frees the support profile from having to take on a supporting function with respect to the drive means. This means that even with the aforementioned 20 kg motor, the support profile can be made relatively thin-walled.

Advantageously, the support profile is clamped or clamped in this area between the holder and the associated base. This is a particularly simple way to transfer the weight of the drive means into the associated base without putting any strain on the support profile.

Furthermore, a gate is provided within the scope of the invention. The gate is provided with feet, which are placed at one end on a footprint or are stationarily inserted into a support device which is provided with or forms such a footprint. Furthermore, the gate includes one of the aforementioned support profiles. This is attached to the feet by means of the fasteners in such a way that the support profile is arranged at a predetermined distance from the footprint. This results in a structural unit for arrangement in a spinning preparation process chain.

The invention additionally relates to an arrangement. This has a spinning preparation machine and the gate in question. Its support profile is arranged so that it extends essentially parallel to a sliver inlet direction on the spinning preparation machine and, viewed in the sliver inlet direction, is arranged in front of the spinning preparation machine. The drive means is able to rotate the at least one shaft in such a direction of rotation that the contacted sliver is conveyed from an associated storage container by means of the contact surface in the direction of the spinning preparation machine.

Figure 1 shows an arrangement 1 according to a first embodiment of the invention.

The arrangement 1 essentially comprises a spinning preparation machine 2, which is designed here as a stretch and is partially shown, and a gate 4 arranged in front of it with, here eight, storage containers in the form of cans 3 placed underneath. A sliver (not shown here) is each made from the cans 3 via an associated, The sliver roll of a respective transport section 40 and guide sections 30, described in more detail later, are guided in the direction of route 2.

The gate 4 essentially comprises a support profile 10, which is arranged on three feet 5 as an example. The feet 5 are attached to a floor, not shown, for example by screwing.

Preferably the route 2 or the individual sliver rolls of the transport sections 40 transport the respective sliver away from the respective can 3 and redirect it towards the route 2.

Figure 2 shows gate 4 of Figure 1 in greater detail and without pitchers 3.

The support profile 10 has a motor 60 at its left end, preferably facing away from the spinning preparation machine 2, which will be explained in more detail later. Furthermore, a signal light 50 is arranged at this end of the support profile 10, which will also be explained in more detail later.

The support profile 10 here has, by way of example, several top cover parts 11, of which the right one is omitted, as well as base parts 12 which are also located underneath and are fastened to the cover parts 11. Both the cover parts 11 and the base parts 12 are U-shaped in cross section in the example shown, with the two U's being arranged open to one another. The cover parts 11 form a cover section, and the base parts 12 form a bottom section of the support profile 10.

Preferably the base parts 12 are fastened to one another by means of connecting elements 7, as seen in the longitudinal direction of the support profile 10. The same can also apply to the cover parts 11. However, they are advantageously attached to the base section. This makes it possible to remove the cover parts 11 in the desired areas and thus gain access to the interior of the support profile 10 from above. This is very advantageous compared to the known overhead installation.

Furthermore, it can be seen that on the front side of the support profile 10, for example the base parts 12, the aforementioned sliver rolls 41 or the transport sections 40 having them and the guide sections 30 are designed to protrude.

Figure 3 shows this gate 4 in detail. Here it can be seen particularly clearly that both rods 34 belonging to a respective guide section 30 and the sliver rolls 41 are attached to the base parts 12.

Furthermore, a drive belt 6 is shown in the section of the support profile 10 shown at the top right, on which the right cover part 11 is missing for the sake of explanation.

Each rod 34 has one or more guide elements 31, which are U-shaped in cross section. Each cross section runs transversely to the longitudinal extent of the support profile 10, and each U is in the direction away from the rod 34 and the floor (not shown), i.e. open at the top. Furthermore, it can be seen that the guide elements 31 closest to the support profile 10 have a respective distance a, b and c, with these distances decreasing in the direction to the left. As a result, the slivers guided therein are guided further and further in the direction of the support profile 10.

Figure 4 shows the right end of the support profile 10 from Figure 3 in greater detail.

Each transport section 40 has a sliver roll 41 which is arranged outside the support profile 10. The sliver roll 41 merges into a cover 42 at its end facing the support profile 10 or is provided with one. Furthermore, the transport section 40 has a shaft section 44, which is arranged in the hollow interior of the support profile 10 and extends essentially transversely to the longitudinal extent of the support profile 10 and the feet 5. At its ends arranged in the area of vertical side walls 15, 16 of the base part 12, each transport section 40 has a bearing 43, by means of which the shaft section 44 is accommodated in the respective side wall 15, 16 in a freely rotatable and stationary manner with respect to movement along its longitudinal extent is. For this purpose, the through openings provided in the side walls 15, 16, which will be explained in more detail later, are aligned along the longitudinal extent of that same shaft section 44.

The shaft section 44 is formed in one piece with the sliver roll 41. In this case, the transport section 40 is pushed from the left side wall 16 through the associated through opening towards the through opening of the right side wall 15 and fixed there. Alternatively, the shaft section 44 has a respective fastening section at its ends, for example in the form of a respective threaded opening, into which a corresponding sliver roll 41 is screwed with a corresponding threaded pin. Alternatively, the shaft section 44 has a threaded section which protrudes in the direction of the associated sliver roll 41 and onto which the sliver roll 41 is screwed. Or both parts 41, 44 have threaded openings into which a separate threaded pin is screwed. However, any other fastenings such as jamming, gluing, etc. are conceivable.

The cover 42 serves to protect the interior of the support profile 10 from dirt from the outside, for example in the form of fibers from the transported sliver.

The shaft section 44 has a belt roller 45 in the area of the interior of the support profile 10, around which the belt 6 is placed. So that the belt 6 also comes into effective contact with the belt roller 45, a deflection roller 17 is also provided, which is attached to the right side wall 15 via an axle 18, for example. However, it is also possible for the axis 18 to be attached to the left side wall 16 in a stationary manner and/or in a freely rotatable manner via a corresponding bearing. In the example shown, the belt 6 runs from behind over the areas of the circumferential surface of the roller 45 that point forward and upward, over areas of the circumferential surface of the roller 17 that point downward and backward, and over areas of the circumferential surface of the roller 17 that point up, forward and downward Circumferential surface of a roller 81 of a deflection and tensioning section 80 and then back again in the direction from which the belt 6 according to Figure 4 comes from in terms of drive.

The belt 6 is stored pretensioned by means of the section 80. For this purpose, the roller 81 is attached to a guide section 83, which will be explained in more detail later, so that it can rotate freely. In addition to the roller 81, the section 80 includes a stop part 86, which is coupled here, for example, by means of a spindle arrangement. This can be used to change the position of the roller 81 in the direction of the longitudinal extent of the support profile 10. This allows any expansion of the belt 6 to be compensated for during operation.

Furthermore, a plate-like fastening section 19 is shown here, which serves to fasten the associated base 5.

The rod 34, preferably of each guide section 30, passes through an associated through opening 14, here in the side wall 16, preferably into a corresponding one that is aligned with it and is not visible here Through opening 14 in the side wall 15 is inserted in a stationary and rotationally fixed manner. Here below the sections 30, 40, cable channels 9 are arranged inside the support profile, which are advantageously attached to the inside of the unmarked bottom section of the respective base part 12 enclosed by the side walls 15, 16. They are used for the safe and protected laying of cables and, if necessary, for arranging other elements such as a sensor circuit.

Figure 5a shows the other end of the support profile 10. This means that both the signal lights 50 and the motor 60 can be seen here.

The motor 60 is attached to the front side of the support profile 10 via a holder 61. In the example shown, the holder 61 is placed on the inside of an associated base part 12 and fastened to an associated base 5 arranged below the support profile 10 by means of four screws 8. The holder 61 preferably replaces the fastening section 19 otherwise located here and also takes over its function. I.e. The support profile 10 itself does not carry the motor 60 with holder 61, but rather this takes care of the attachment between the base 5 and the holder 61. This means that the weight of the motor 60 - holder 61 arrangement is guided into the base 5. The support profile 10 is therefore not exposed to the risk of bending or twisting due to the motor 60. The motor 60 is covered by a cover 63 on its drive side, where the output shaft 62 is arranged. The cover 63 is fastened here to the holder 61 by means of two screws 8, as indicated by the dash-dotted lines.

The signal light is also preferably attached to the holder 61 via two screws.

Furthermore, it can be seen that the belt 6 runs into and out of that holder 61 and is again placed around a corresponding roller 45 in connection with a deflection roller 17.

Furthermore, it can be seen that the shaft section 44 is preferably sealed off from the outside in a dirt-tight manner by means of a cover 46 at its right-hand end, on which no sliver roll 41 is arranged. Alternatively, of course, instead of the cover 46, a sliver roll 41 can also be attached to the right. This also applies to the rod 34 in relation to the guide element(s) 31. The cover 46 is fastened here to the side wall 15 of the associated base part 12 by means of two screws 8.

Figure 5b shows the arrangement of Figure 5a without the parts accommodated in the support profile 10 and with the cover part 11.

As a result, the through openings 13, 14 can be seen, in which an associated bearing 43 of the transport section 40 or an associated rod 34 of a guide section 30 is inserted.

Preferably, each through opening 13 has a recess 25, which is preferably semicircular in cross section, at two opposite locations on its inner circumference. In the case of the side wall 15, the aforementioned screws 8 pushed through the cover 46 are pushed through the recesses 25 into the interior of the base part 12, protrude into the interior of the support profile 10 and are screwed to corresponding threaded openings in the associated bearing 43, which is from the other side of the side wall 15 rests against it. The cover 46 is thus fixed to the base part 12. In the case of the side wall 16, only the cover 46 is missing.

Figure 6 shows the support profile 10 from Figure 1 in greater detail. Only a cover part 11, a base part 12 and a connecting element 7 of the support profile 10 are shown.

The connecting element 7 is designed in two parts as an example. It comprises two angle parts which are attached to the inside of the base section and one of the two side walls 15, 16 by means of screws 8 of two immediately adjacent base parts 12, of which only the rear one is shown here.

To fasten the cover part 11, it has two side walls 21, 22, which are designed analogously to the side walls 15, 16 of the base part 12. The side walls 21, 22, with their free edges running in the longitudinal direction of the support profile 10, each have a semicircular recess 20 in the direction of the base part 12. The side walls 15, 16 accordingly have two through openings, not visible here, which are aligned with a respective recess 20. From an outside of the respective side wall 21, 22, a screw 8 is pushed through the associated pairing of recess 20 and through opening and fixed by means of a nut 24. The side walls 21, 22 lie on the outer sides of the side walls 15, 16 and thus stabilize them against any bending. Instead of the respective nut 24, a threaded rivet protruding towards the interior of the transport profile 10 can also be provided.

The side walls 21, 22 preferably each include a recess 23 for inserting the cover 42 described above. This protects the cover part 11 in conjunction with the associated one Cover 42 effectively protects the interior of the support profile 10 from contamination.

Figure 7 shows the deflection and tensioning mechanism 80 from Figure 4 in an exploded view. For better differentiation, the dashed lines indicate a mounting direction downwards Figure 7 and the dash-dotted lines represent a montage in other directions.

In the example shown, the guide section 83 consists of two preferably identical parts. But it can also be formed by a single part. In the example shown, the two parts are cuboid-shaped and have two projections 84 in a rear area here, which extend towards each other and along the longitudinal extent of the respective part. Both parts are provided with threaded openings 87 on their sides facing away from the projections 84. The six screws 8 arranged here at the bottom left are from the outside of the ones not shown here and according to Figure 4 right side wall 15 is screwed through this into an associated threaded opening 87 and fixes the associated part of the guide section 83 on that same side wall 15. This creates a space in the area between the side wall 15 and the projections 84 which serves to accommodate a sliding block 89. The space therefore forms a linear guide for the sliding block 89 along the longitudinal extent of the support profile 10.

From a side of the guide section 83 facing away from the threaded openings 87, a screw 8 shown here at the top left is screwed through the roller 81 with a threaded section 90 into a threaded opening 87 of the sliding block 89 on the left here. This screw 8 has a thread section 90 between the screw head and the screw head Bearing section 91 on which the roller 81 is arranged freely rotatable or non-rotatable by means of force and / or positive locking. In the latter case, the bearing section 91 is designed like a sleeve and is arranged on the other screw 8 in a freely rotatable manner.

From the same side of the guide section 83, a screw 8 shown here at the top right is screwed through a through opening 88 in a threaded rod 82 with a threaded section 90 into a threaded opening 87 of the sliding block 89 on the right here. This screw 8 also has a bearing section 91 between the screw head and the threaded section 90, on which the through opening 88 of the threaded rod 82 preferably comes to rest in a freely rotatable manner with respect to the other screw 8. The threaded rod 82 is thus arranged in a stationary manner with respect to the sliding block 89.

The threaded rod 82 is here provided on the right side of the through opening 88 with an external thread section 90 which extends to the end facing away from the through opening 88 of the threaded rod 82. From this end, the stop part 86 with a through opening 88 is pushed onto the threaded rod 82. Analogous to the parts of the guide section 83, two screws 8 are now screwed through the same side wall of the support profile 10 into a corresponding threaded opening 87 in the stop part 86. This also means that the stop part 86 is fixed to the support profile 10. The stop part 86 can also be formed in one piece with the guide section 83 or a part thereof, so that screws 8 can be saved if necessary.

A washer 85 with a through opening 88 is preferably pushed on from the free end of the threaded rod 82 on the right here. Furthermore, two nuts 24 with their threaded openings 87 are screwed onto the threaded rod 82, so that the washer 85 is arranged between the stop part 86 and the nuts 24. The nut 24 facing the washer 85 is used to adjust the distance of the through opening 88 of the threaded rod 82 and thus the roller 81 to the stop part 86. The tension of the belt 6 can be adjusted and adjusted, as the belt 6 expands over the operating time and can therefore increase in length. The other nut 24 serves as a lock nut and fixes the first-mentioned nut 24 in its screw position on the threaded rod 82.

Preferably, for example, a compression spring, for example in the form of a helical spring, is arranged between the stop part 86 and the washer 85. This thus pushes the stop part 86 and the washer 85 away from each other. This results in the through opening 88 of the threaded rod 82 being pushed away from the motor 60. This means that the spring “pulls” the drive belt 6 tight and thereby tensions it. I.e. it is a section 80 that automatically tightens the belt 6. It is therefore not necessary to do this manually using the two nuts 24. As a result, the threaded rod 82 only needs to have an external thread at its end facing the nuts 24 with a length that is sufficient to accommodate the two nuts 24. Alternatively, instead of the nuts 24, a fixed stop, for example in the form of a snap ring, can be provided, so that the rod 82 does not require any external thread at all.

Additionally or alternatively, a sensor system is provided which can detect excessive expansion of the belt 6. In the example shown, this can be done analogously to the contact pin pairs 36, 37. Are, for example the sliding block 89 and the stop part 86 are designed to be electrically conductive on the mutually facing sides in a possible contact area with one another, and if the sliding block 89 and the stop part 86 are coupled to a current detection circuit, it can be detected by means of a contact between the sliding block 89 and the stop part 86 that the Belt 6 has reached its maximum permissible extension. This can be made visible to the outside by means of a lighting section 51 of the signal light 50, for example by means of a yellow light.

As an alternative to the electrically conductive design of both elements 86, 89, a pressure switch can be arranged, for example, on the side of the stop part 86 facing the sliding block 89, which is actuated and, depending on the version, allows or blocks a current flow if the sliding block 89 comes too close. Alternatively or additionally, non-contact sensors are conceivable, for example in the form of a light barrier, the elements of which are arranged, for example, on the mutually facing sides of the parts of the guide section 83 in the area of the movement space of the sliding block 89. It is therefore possible to easily detect when the stretch of the belt 6 is too great. If the belt 6 breaks, this is also detected by the sliding block 89, which is moved towards the stop part 86 by means of the spring. I.e. This condition can also be detected.

Preferably or alternatively, all shaft sections 44 advantageously have rotation sensors, for example in the form of incremental encoders. The rotation sensors are set up to detect whether the respective shaft section 44 rotates or not when the output shaft 62 of the motor 60 rotates. Instead of incremental encoders, other sensors such as light barriers are also possible, with a detection area on the circumferential surface The projection formed on the respective shaft section 44 arrives during one revolution of the shaft section 44.

Furthermore, the rotation sensors are preferably set up to detect a speed of the respective shaft section 44. If there are excessive speed differences between the shaft sections 44, for example of more than 5% in pairs, this is a sign that the belt 6 is no longer functioning properly; For example, it may have slipped off one of the rollers 17, 45. In the case of in Figure 7 Section 80 shown, this can be interpreted as meaning that the belt 6 needs to be tightened or replaced, which can be signaled by means of the signal light 50. i.e. a person concerned is informed to look at the belt 6.

If the section 80 is designed to be self-tightening and/or if it has the aforementioned sensors, it can also be reliably detected when the belt 6 needs to be replaced. In this case, for example, the engine 60 is switched off and the signal light 50 is set to flash red to signal this.

If the sensor system also detects when the motor 60 is being operated, for example by also having a rotation sensor for its output shaft 62, it can be reliably detected even when the shaft sections 44 are stationary, i.e. if there is no difference in speed between them, if the belt 6 is not working properly functions. This condition occurs in particular if the belt 6 is torn at a point between the output shaft 62 and the rollers 17, 45 closest to it in the belt tension direction. In this case, the motor 60 would "press" the belt 6 in the direction of the rollers 17, 45, but the rollers 17, 45 would stand still. A belt break can therefore be reliably detected, for example by means of be signaled by a red flashing signal light 50. The engine 60 can also be switched off immediately.

Figure 8 shows the drive mechanism in greater detail in two partial views, Figure 8a on the engine side of the support profile 10, not shown, and Figure 8b on the opposite side with section 80.

According to Figure 8a Only the output shaft 62 of the motor 60 is shown, around which the belt 6 is guided. The upper run of the belt 6 runs, as an example, parallel to the longitudinal extent of the support profile 10 as explained above and in Figure 8b shown role 81 of section 80.

The lower run of the belt 6 is deflected many times. First, coming from the output shaft 62, it hits the upper region of the circumferential surface of a shaft section 44, runs past it and then towards a lower region of an adjacently arranged roller 17. The belt 6 is thereby turned by an angle of preferably more deflected downwards by 45°. The belt 6 therefore hits the lower region of the peripheral surface of the roller 17, runs past it and then towards an upper region of a next shaft section 44. The belt 6 is now deflected upwards by an angle of preferably more than 45 ° . The deflection process is then repeated for each additional shaft section 44.

Behind the last shaft section 44 in this direction, which is closest to section 80, a roller 17 is preferably also arranged in the direction of section 80. However, this could also be omitted.

In any case, the lower strand of the belt 6 runs from this last shaft section 44 or the last roller 17 in the direction of roller 81 and runs around it again in the direction of the output shaft 62.

Figure 9 shows an arrangement 1 according to a second embodiment of the invention.

In contrast to the first embodiment of the invention, the arrangement 1 has a gate 4 next to the spinning preparation machine 2 that is designed in two rows. That is, the support profile 10 has sliver rolls 41 on both sides.

Figure 10 shows the gate of Figure 9 in greater detail and in two views. The cover part 11 has been omitted for the sake of the description.

Figure 10a shows the gate 4 in a perspective view from above in relation to Figure 9 .

Here it can be clearly seen that a sliver roll 41 adjoins each shaft section 44 on both sides. That is, instead of the cover 46 explained above, a separate sliver roll 41 is attached to the relevant location.

The sliver rolls 41, which are attached to one and the same shaft section 44 or are formed in one piece with it, are sealingly attached to the support profile 10 or the side walls 15, 16 of the base part 12 by means of a respective cover 42.

Furthermore, the rollers 45 can be seen, which are attached to the respective shaft section 44. Furthermore, the deflection rollers 17 are shown, which ensure that the belt 6 has the largest possible contact area with the drive rollers 45.

Furthermore, a first guide section 30 is arranged at the end of the support profile 10 that points to the right and is closest to the spinning preparation machine. This guide section 30 has an associated rod 34, which extends essentially transversely to the longitudinal extent of the support profile 10 and the feet 5. There is a light barrier element 39 at both ends of the rod 34. One light barrier element 39 is designed to emit radiation, with the other light barrier element being designed to absorb or detect radiation. During normal operation, six guide elements 31 guide sliver material in the form of, for example, six slivers in the direction of the spinning preparation machine 2. If a tear occurs in one of these slivers, this leads to the sliver in question falling downwards, i.e. in the direction of the floor, not shown, between the spinning preparation machine 2 and the guide section 30 and thus falling or getting into the detection range of the two light barrier elements 39. This can be detected by a circuit coupled to the light barrier elements 39. In the case of such detection, the drive means 60 is preferably switched off by means of this circuit, and thus the entire gate 4 is switched off. In order to realize this, the belt pull described above is implemented.

The two transport sections 40 arranged on the right border directly on an associated guide section 30. Both guide sections 30 are analogous to the guide section 30 shown on the right formed by means of a respective rod 34, which, however, in contrast to the right rod 34, is not inserted in a stationary manner underneath the support profile 10 but through it.

In the example shown, each of these two guide sections 30 has a guide element 31 on both sides of the support profile 10, which is advantageously designed analogously to the six elements 31 of the right guide section 30.

The right of these two guide sections 30 has a freely rotatable lever 38 in the area of the free ends of the associated rod 34. The free rotation can be achieved, for example, by means of a sleeve section, which is preferably arranged without play on the rod 34, which is preferably circular in cross section. In order to avoid movement of the lever 38 along the longitudinal extent of the rod 34, unmarked ring sections are fixedly attached to the rod 34 on both sides of this sleeve section.

Preferably both ring sections each have a contact pin 37 on the outside, which extends essentially transversely to the longitudinal extent of the rod 34.

Each lever 38 has a freely rotatable roller 33 at its free end. The axis of rotation of each roller 33 runs parallel to the longitudinal extent of the rod 34. The rod 34 and the sliver rolls 41 are arranged so that each sliver roll 41 lies in the pivoting range of an associated one of the two rollers 33. This means that each roll 33 comes into contact with the associated sliver roll 41 at some point when rotating through 360° around the rod 34.

Each roller 33 is preferably designed to be electrically conductive on its outer circumference. The same applies to the associated sliver roll 41, at least in the possible contact area with the associated roll 33. Furthermore, 33 inlet eyes 32 are formed below each roll, through which the sliver is guided away from a can 3, not shown, in the direction of the sliver roll 41. The sliver is then guided between the rollers 33, 41 in the direction of the associated guide section 31. Im in Figure 10a In the example shown, the rollers 33 are assigned to the two outer guide elements 31 of the right guide section 30. If the can 3 located under the respective transport section 40 becomes empty or if a sliver tear occurs, this will result in no sliver being transported between the rollers 33, 41 at some point. Due to the gravity of the lever 38 and the roller 33 attached to it, it then lies on the associated sliver roller 41. Since both rollers 33, 41 are designed to be electrically conductive in their associated contact areas, this can be used to introduce electrical current into one of the rollers 33, 41 and to detect contact on the other roller 41, 33. For this purpose, the electrically conductive areas of the rollers 33, 41 are coupled via the lever 38 to the sleeve section and the rod 34 or the shaft section 44 to a detection circuit which is able to stop the motor 60 in the presence of such electrical contact and thus to switch off gate 4 (temporarily). To make this possible, the associated rod 34 is electrically insulated and inserted into the support profile 10 or its base part 12. This makes the aforementioned electrical connection possible.

When changing the can, it is preferably provided that the lever 38 is pivoted away from the associated sliver roll 41. For this purpose, it is provided according to the invention that a contact pin 36 provided on the lever 38 is electrically connected to an associated contact pin 37 Contact is made. This is the signal for the aforementioned circuit that the gate 4 may not be operated and it can switch off the motor 60.

Once the can has been changed, i.e. the associated sliver has been guided via the associated sliver roll 41 to the guide section 30 on the right in Figure 10a, the lever 38 can be pivoted back again. Since the sliver is again arranged between the rollers 41, 33, there is no electrical contact and the gate 4 can work as usual.

The guide section 30 to the left of it is designed similarly. However, the rod 34 is longer and preferably has operating elements 70 at both ends. As an example, these each have three buttons 71 here. The gate 4 can be stopped, restarted or even just tested using the keys 71.

On the left side of this guide section 30 there is another rod 34, which, however, is arranged below the support profile 10. Analogous to the right guide section 30, it again has light barrier elements 39 at both ends.

However, the light barrier elements 39 can also be attached to the aforementioned guide section 30 or to its rod 34. For this purpose, they are designed continuously in the fastening area.

The left transport section 40 and the left guide section 30 essentially correspond in structure to the arrangement of the right guide section 30 and the right transport section 40. However, the guide elements 31 are missing here.

Figure 10b shows the gate 4 in a perspective view from below and thus on the underside of the base parts 12 facing the feet 5.

As can be seen, the support profile 10 in the example shown here consists of two base parts 12, which are fastened to one another by means of sixteen screws 8. Furthermore, it can be seen that each base 5 is attached in a stationary manner to the support profile 10 or its base part 12 via a plate-like fastening section attached to an end facing the support profile 10, also by means of four screws 8 here.

Furthermore, it can be seen that both the rod 34 of the right guide section 30 and the middle rod 34 (only with light barrier elements 39) are also attached via two screws 8 to the underside of a respective, here exemplarily the same, base part 12, which points in the direction of the feet 5 .

It is of course possible to insert and attach these rods 34 through the support profile 10, preferably in the middle, in the same way as the rod 34 arranged on the left. If the respective rod 34 protrudes into the movement path of the belt 6, each rod 34 can have a roller at the respective contact point with the belt 6 that is freely rotatable on it and stationary in the longitudinal extent of the respective rod 34, around which the belt 6 is positioned is guided.

Figure 11 shows an arrangement 1 according to a third embodiment of the invention.

Arrangement 1 essentially corresponds to that in Figure 10 shown. However, the rods 34 of the three right guide sections 30 are designed differently. In addition, these rods 34 have sensors 35 at their ends instead of the light barrier elements 39 that face one another in the previous embodiments and therefore cover the area between them sensorily, the detection areas of which point away from one another and thus outwards in the direction of the respective guide element 31.

The sensors 35 are therefore designed in such a way that the passing sliver material reflects light emitted by the respective transmitter 35. If this reflection is missing, it is assumed that there is, for example, a sliver tear or a can change. In both cases, the gate 4 or its motor 60 is stopped.

Figure 12 shows a section of gate 4 from Figure 11 in greater detail.

Here it can be seen particularly clearly that the sensor 35 points away with its detection area from the support profile 10 or its base part 12 shown here in relation to the associated guide element 31.

Furthermore, it can be seen that the rod 34 is not straight as in the previous embodiments but has an offset. The cranking is such that the rod 34 extends from a section here preferably below the support profile 10 in a cranked manner in the direction of its free ends in the direction of the associated sliver roll 41.

In the example shown, a guide element 31 is arranged at each end of the rod 34 of the right guide section 30. Each guide element 31 is arranged so that the sliver from the can 3 arranged immediately below is securely between the in Figure 11 the sliver roll 41 and the associated roll 33 arranged on the right side of the support profile 10 are moved. The guide section 30 (with control element 70) which is arranged closest in the direction of the spinning preparation machine 2 has two guide elements 31 which are arranged very close to the support profile 10. This serves the purpose of guiding the slivers removed from the cans 3 arranged on the right inwards in relation to the support profile 10. This makes it possible to arrange the next removal point in relation to the can 3, which is now located in the middle at the front, in the same way as with the front, right can 3. I.e. The closest guide section 30 with sensors 35 has the elements 31, 35 preferably at the same distance from the support profile 10 as the aforementioned guide section 30 arranged on the right.

As a result, the rod 34 arranged on the right side of the left transport section 40 also has guide elements 31. However, these are further away from the support profile 10 than the aforementioned guide elements 31 for redirecting the sliver. This ensures that the two slivers are aligned parallel to one another by the two cans 3 arranged at the front right. This makes it possible to remove the sliver from the third front can 3 at the same point in relation to this can 3 as with the other two cans 3. The same arrangement can be found in mirror image on the side of the support profile 10 that points backwards.

In order to align the sliver removed on the left accordingly, the left guide section 30 is designed with three guide elements 31 on each side of the support profile 10 so that the respective sliver is aligned in the direction of the spinning preparation machine 2.

Here too there are preferably levers 38 with contact pins 36.

Figure 13 shows a modification of the base part 12 from Figure 5 . The difference lies in the design of one of the through openings 13. The front through opening 13 here is open to the upper edge facing the cover part 11, not shown. This makes it possible, during assembly, to push the relevant shaft section 44 from the interior of the support profile 10 through the rear passage opening here and then to insert it from above into the passage opening 13, which is open at the top. An insert part 26 is then inserted from above into the through opening 13 which is open at the top. Here, a front plate-like section of the insert part 26 comes to rest in the gap above the otherwise circular through-opening. A rear, plate-like section comes to rest on an inside of the side wall 15. Screws 8 are screwed from the outside of the side wall 15 through corresponding through openings 27 into a corresponding threaded opening 28 of the insert 26 and fix the insert part 26 on the side wall 15.

Alternatively, both through openings 13, which are aligned with one another, are designed to be open at the top.

The invention is not limited to the prescribed embodiments. They can, within the scope of the claims, be exchanged for one another or combined with one another in parts or in whole.

The number of sliver rolls 41 on the respective sides of the support profile 10 can vary.

The components of the base parts 12 or cover parts 11 arranged between the side walls 15, 16 or 21, 22 do not have to be plate-like. They can take any suitable cross-sectional shape. Instead of several cover or base parts 11, 12, only one cover or base part 11, 12 can be provided.

The guide sections 30 are only optional. They can also be omitted.

The rods 34 technically correspond to bolts.

The cover and base parts 11, 12 are advantageously designed as folded sheet metal parts, which enables very inexpensive production.

Instead of the aforementioned section, any other type of spinning preparation machine, such as a winder, can be provided. The sections 34, 40, etc. can be combined with one another or interchanged with one another in any way.

The elements arranged below the support profile 10 can just as easily be arranged through the support profile 10 analogously to the transport sections 40.

Another option is, for example, a linear motor which is attached to the inside of the cover part 11 instead of at one end of the support profile 10 and is able to move the belt 6 inside the support profile 10.

All screws 8 are preferably designed to be operated with one and the same tool.

The deflection rollers 17, 81 can be formed by fixed projections projecting into the interior of the support profile 10, which are designed to be easy to slide in the contact area with the belt.

The levers 38 preferably form an angle of 90° with the respective rod 34. But it can also be pointed and, for example, be 80°.

Instead of in the side walls 15, 16, the through openings 13, 14 can also be formed in the side walls 21, 22.

With the invention it is possible to arrange the support profile 10 in such a way that its end face with the drive means 60 faces the spinning preparation machine. In this state, only the drive direction of the drive means 60 needs to be reversed. This makes arrangements with two gates 4 possible, the sliver rolls 41 of which are designed in a single row and extend towards one another. This means aisles can be implemented between two gates 4, through which the cans can be operated, for example changed.

As a result, the invention creates a universally applicable and very flexible possibility of realizing gate arrangements for spinning preparation arrangements. This also makes it possible to couple very large cans 3 with a spinning preparation machine 2.
