Description

The invention relates to a device for receiving spools or tape windings or the like.

A sanding belt store is already known (DE-A1-35 34 172). In this store, there are a plurality of bearing cheeks formed from sheet metal and connected to a rear wall, between which the wound sanding belt can be inserted. Due to the fixed arrangement, only sanding belt rolls of a fixed width can be accommodated.

Also known is a device for holding coils (GB-A-2 230 794), in which the coils are mounted on axles arranged on T-shaped supports. The axes can be designed telescopically to accommodate coils of different widths. However, this means an increase in material and costs.

The invention has for its object to provide a simpler and more universal device for accommodating objects wound on spools.

To achieve this object, the invention proposes a device with the features of claim 1. Further training is the subject of the subclaims.

The mounting of the bearing cheeks in different relative positions on the cross rail makes it possible to individually adapt the device to the respective needs. The size of the device and thus its capacity can be changed by changing the cross rail of another length. By attaching the at least one cross rail, for example directly to the rear of the device, bearing cheeks can be used which are designed to project forward, so that only little material is required to form the device and the device can be light in weight and require little space.

According to the invention it can be provided that the device has on its front side a holder for the free ends of the objects wound on the coils. This holder can in particular also be adjustable. The holder makes it possible to always take the object wound on the spool immediately. The objects can not only be sanding belts, but all objects that can be wound on spools, for example hoses, electrical cables, shrink sleeves, sanding belts, etc.

According to the invention, the holder for fixing the free ends can be matched to the respective object, for example to the dimensions and / or the shape of the object.

According to the invention it can be provided that the device has a braking device in order to prevent the coils from rolling when the coils are removed.

In a further development of the invention it can be provided that the device has two transverse rails arranged parallel to one another at a mutual spacing. These can in particular be arranged one above the other. When using only a single cross rail, it is possible that the bearing cheeks are additionally supported on a rear wall. If two cross rails are used, the bearing cheeks can only be attached and supported on the cross rails.

In particular, it can be provided that the cross rail is formed from a round tube or has a round tube. Since round tubes are generally available, the end user can then also enlarge or reduce his device by simply using another round tube as a transverse rail.

In a further development of the invention it can be provided that the bearing cheeks can be displaced along the cross rail and can be fixed in any position. This can be achieved that the device can also be used for coils of different widths. For example, there are sanding belts in different widths, with the rolls of sanding belt then of course also having different widths.

To attach the bearing cheeks to the cross rails, it can be provided that the bearing cheeks have openings through which the cross rails can be inserted or with the help of which the bearing cheeks can be pushed onto the cross rails. The dimensions of the openings of the openings can be adapted to the dimensions of the cross rails, so that the opening alone can be sufficient for holding and possibly also for fixing the bearing cheeks.

In particular, it can be provided that an opening has a non-closed circumference to form a slot. The opening can then be dimensioned so that it clamps the bearing cheek to the cross rail. A screwdriver or other tool can be inserted into the slot and the slot and thus the opening can be expanded by slightly tilting it if the bearing cheek is to be moved.

In a further development, the receptacle for the stub shafts of the coils to be supported can be formed by recesses in the bearing cheeks which are open at the top and on the sides. In this way, the coils with their shaft journals can be inserted into the bearing cheeks from above. This is particularly important in the case of a device in which a plurality of coils are arranged next to one another.

The invention proposes in a further development that the holder for fastening the cross rail has two angle profiles with which the ends of the at least one cross rail can be connected, in particular screwed. Depending on the application, these angle profiles in turn can be screwed onto a wall, for example. Of course, the angle profiles can also be part of a shelf or connected to a shelf.

For the storage of coils, which for example have only a cylindrical core, on which the tape or the hose is wound, it can be provided according to the invention that the device has a pair of bearing inserts for each coil, each of which has a stub shaft for receiving the bearing cheek and have an approximately cylindrical approach for insertion or insertion in the coil core.

In particular, it can be provided that the bearing insert has a shoulder which limits the insertion or insertion into the coil core and is formed in particular on arms of the bearing insert which form a lateral boundary for the objects wound on the coil core. In this way, it becomes possible, for example, to simply wind the objects onto a spool core made of cardboard and not to provide any lateral limitation, but instead by means of a cable tie or the like. just set. The lateral limitation of the coils is then formed by the bearing inserts provided with the arms, which belong to the receiving device and do not form a disposable part.

To slow down the rolling of the coils, it can be provided that the bearing insert adjacent to the stub shaft has a locking wheel, in particular integrally formed, with which a tongue formed on the bearing cheek interacts.

In a further development it can be provided that the cylindrical extension of the bearing insert is formed by individual projections arranged on the arms, the notches or the like. have on the outside.

To increase the stability of the bearing insert, it can be provided that the arms are connected by a ring.

The invention proposes that the device may have a tear-off rail on the holder for the free ends. This tear-off rail is intended in particular for flat objects, for example sanding tape or adhesive strips. In order to protect these objects, it can be provided according to the invention that a rolling element is arranged parallel to the tear-off rail, the objects to be removed being passed between the tear-off rail and the rolling element. In particular, it can be provided that the rolling element is spring-loaded against the tear-off rail.

The invention proposes that the bearing cheeks and / or the bearing inserts are injection-molded in one piece from plastic.

The invention proposes that the receptacle for the stub shafts is arranged in the front end region of the bearing cheeks.

In the schematic overview of FIG. 1, a device for receiving coils can be seen, which has five bearing cheeks 1. The bearing cheeks 1 are all identical and arranged parallel to one another. They extend transversely to two cross rails 2, of which only the upper one can be seen in FIG. 1. Both cross rails 2 are in the region of their ends on a vertically extending angle profile 3 screwed on. Both angle profiles 3 form the holder for the cross rails 2. The angle profiles 3 can, for example, be screwed to a wall, so that the entire holder is attached to the wall itself. But it is also possible that the angle profiles are 3 parts of a shelf or screwed to a shelf.

The cross rails 2 are designed as round tubes and inserted between the angle profiles 3 so that a screw is screwed into the inside of the tube from the outside. Screws that cut their own threads can be used for this. With an appropriate selection of the inside diameter of the pipe, pre-drilling or tapping is not necessary.

The bearing cheeks 1 have openings through which the cross rails 2 are inserted. As a result, the bearing cheeks 1 are both fixed and held on the cross rails 2.

The two cross rails 2 are arranged vertically one above the other. Their distance is chosen so that the stability of the bearing cheeks 1, which are only attached to the cross rails 2, is sufficient.

A rail 4 is screwed to the two outer bearing cheeks 1 on the underside, this being shown in FIG. 1 only for the left bearing cheek 1. The rail 4 is directed forward and chosen so long that it extends beyond the front edge of a coil to be used. The two rails 4 are then connected to one another by a cross strut 5, on the front 6 of which, for example, a tear-off edge can be formed. A rolling device 7 is arranged at a short distance below the cross strut 5, parallel to the latter. The rolling device 7 contains a plurality of rollers 8 mounted on a common shaft the unrolling device 7 and the underside of the cross strut 5 there is a small space, it being possible for the unrolling device 7 to be spring-loaded in the direction of the cross strut 5.

A coil with a wound object is inserted between two adjacent bearing cheeks 1 of the device of FIG. 1, specifically in receptacles which are arranged in the front region of the bearing cheeks 1 and are not shown in FIG. 1. The free end of the wound object, for example an abrasive belt, is inserted between the cross strut 5 and the unrolling device 7 and protrudes from the front. Due to a possible preload of the rolling device 7 or due to a narrow distance, the free end remains fixed there, so that the user can take it immediately.

A view of the arrangement of FIG. 1 is shown in FIG. 2. In this case, a total of five bearing cheeks 1 are lined up on the round tubes 10. The round tubes 10 are screwed onto the angle profiles 3 with the aid of screws 11. The cross strut 5 contains in its respective end region two elongated holes 12 through which screws or rivets for fastening the cross strut 5 on the rails 5 pass. Different lengths or different distances between the two outer bearing cheeks 1 can therefore be compensated for.

Each bearing cheek 1 has in the region of its free end facing away from the cross rail 2 each a recess 13 which is open at the top and to the side. In the recesses 13 of two bearing cheeks 1, the stub shafts 14 of an abrasive belt reel 16 containing an abrasive belt 15 are inserted. Immediately adjacent is a coil 17 which contains a gasoline hose 18. Here, too, the stub shafts of the respective coil engage in the recesses 13 in FIG Bearing cheek 1 a. Both the grinding belt 15 and the gasoline hose 18 are passed between the crosspiece 5 and the rolling device 7, so that their free end protrudes forward and can be gripped by the user.

The bearing cheeks 1 can be moved along the cross rail 2 and can be locked in any position. This means that the lateral distance between two adjacent bearing cheeks 1 can be freely selected, so that coils of any width can be inserted between the bearing cheeks 1. As can be seen in FIG. 2, the spool 17 with the petrol hose 18 is, for example, wider than the spool 16 with the grinding belt. The two outer bearing cheeks 1 can also be adjusted, which may be necessary if coils of a certain thickness are to be used.

Since the recesses 13 are open at the top, each coil can be removed and used again on its own. Since the cross strut 15 does not need to absorb large forces, its connection with the aid of the two rails 4 is sufficient, so that no further connections between the other bearing cheeks 1 and the cross strut 5 are required.

The coils that can be accommodated in the device according to the invention can have a bobbin with side disks and the stub shafts 14. However, the device according to the invention is also suitable, and in particular is intended for storing and holding coils which have only a cylindrical core, for example made of cardboard, that is to say neither lateral flanges nor a shaft. To accommodate such coils, the invention uses bearing inserts which are connected to the coil core on both sides thereof. A top view of such a bearing insert 20 is shown in FIG. 3.

The bearing insert 20 contains the stub shaft 14 in the center on its side shown. Radially from the center, four arms 21 extend, which can have openings 22, 23. The four arms 21 of equal length are connected in the region of their radially outer end by a ring 24 which not only forms a stabilization of the bearing insert 20 but also prevents, for example, thin cables from slipping in between the arms 21. As shown in FIG. 7, which shows a section through half a bearing insert 20, a projection 25 is formed on the side of the bearing projection 20 opposite the stub shaft 14, which extends from the arm 21 to the rear. This projection 25 has, for example, the arc length of the arm. It is provided with a nose 26 on its outside. The projections 25 of all four arms 21 together form an approach with which the bearing insert can be inserted into the cavity of a core of a coil, as described above. The nose 26 brings about an improved hold on the inside of the coil core.

4 to 6 now show views of an exemplary embodiment of a bearing cheek 1. The long cheek 1 of the embodiment according to FIGS. 4 to 6 contains an opening 31 on its rear side 30 assigned to the transverse rails, the opening and the shape of the diameter of the diameter of the round tube 10 correspond. One of the two openings 31, the upper one in the example shown, contains a non-closed circumference, so that a slot 32 is formed here. The upper opening 31 deviates somewhat from the exact circular shape to the inside or has a somewhat smaller diameter than the round tube 10. This reduces the size of the bearing cheek on the cross rail. The reduction can be canceled by inserting a tool into the slot.

The distance between the two openings 31 corresponds to the distance between the two round tubes 10 or cross rails 2 and is chosen so that the bearing cheek 1 has sufficient stability. In the area of its front side 33 facing away from the transverse rails 2, the bearing cheek 1 has a height which is only half as great. In the area of this front side, the recess 13 already mentioned with reference to FIG. 2 is formed, which is closed at the bottom by a semicircular arch 34. In the view, the recess 13 has the shape of a U, the sides of the U leading vertically upward in the example shown. For example, they could also be inclined backwards. It is also conceivable to bring the two sides of the U somewhat closer together in relation to the diameter of the arc 4 in order to hold the stub shaft 14 of the coils in place.

5 shows, the bearing cheek 1 in its front area 35 is somewhat thinner at the top than in the rest of the area. At the same time, FIG. 5 shows that the recess 13 is divided by a central wall 36 which extends in the longitudinal direction of the bearing cheek 1 and thus divides the recess into two identical parts, both of which are suitable for a stub shaft 14.

On both sides of the thinner part 35 of the bearing cheek 1, a tongue 37 extends, which is connected at one end 38 to the bearing cheek 1 and, moreover, projects freely forward. In this way, it is made in one piece with the bearing cheek 1, but can nevertheless rebound upwards and downwards. In the region of its front end, the tongue 37 has an upwardly directed, semicircularly rounded hump 39, which is arranged centrally under the recess 13.

As can be seen from FIG. 7, which has already been described, the bearing insert 20, on the same side as the shaft end 14, is integrally formed with a locking wheel 40, the shape of which is shown schematically in FIG. This ratchet wheel 40 has a circumference which corresponds approximately to the shape of a gear wheel with rounded teeth. This locking wheel 40 is integrally formed on the bearing insert 20 and dimensioned such that the locking wheel 40 interacts with the hump 39 of the tongue 37 when the coil is inserted. The hump 39 of the flexible tongue 37 tries to get into the valleys of the waves of the ratchet wheel 40 and thereby holds the coil in a certain position. In this way, a locking or braking device is created which prevents or brakes the further rolling of the coil when a hose or a tape is pulled off the coil.

Fig. 9 shows once again the holder on the front of the device according to the invention, namely the crossbar 5 attached to the underside of the rails 4, possibly with a tear-off edge or tear-off rail on its front 6. Below and parallel to the crossbar 5 is a rod 41 with the help lateral leg 42 arranged on which a plurality of rollers 8 are rotatably mounted. The grinding belt, the gasoline hose or the other material is pushed through the space between the roller 8 and the crosspiece 5 and held in this way. In the case of sanding belts, this is guided through in such a way that the side of the sanding belt provided with the abrasive grain rests on the rollers 8, so that metal chips cannot be accidentally sanded and taken away from the sanding belt when the sanding belt is pulled out, which chips are then removed from the sanding belt onto a workpiece could be transferred.

While in the embodiment according to FIG. 9 the distance between the rolling device 7 and the crossbar 5 is fixed, it could also be variable, for example by the rod 41 attached to levers. These could then advantageously be spring-loaded, so that the rolling device 7 tries to put on the underside of the crosspiece 5.

10 shows in simplified form the front view of a device which is provided for storing a total of five coils 51.

In the area in front of the coils 51, the device contains a web 54 formed by an angular profile. The web 54 runs parallel to the common axis of rotation of all coils 51 and extends over the entire width of the device. The web 54 contains a clamping device 55 in each area assigned to each coil. What is not shown in the figure, the object wound on the coil can be fixed in the area of its free end in the clamping device 55. In the example shown, the clamping device contains two or three incisions 56 which start from the upper edge 57 of the web 54 and extend transversely to the longitudinal axis of the web 54. The incisions 56 are closed by an arch. The incisions 56 of each clamping device 55 have, for example, different widths, that is to say different spacing of their side edges 58. In this way, each clamping device 55 can clamp a thicker object in one of the two incisions 56 and a thinner object in the other, so that the coil 51 each Coil position can be used for different objects.

Fig. 11 shows details of a clamping device 55 on a larger scale. In the clamping device 55 of Fig. 11, it contains a total of three incisions 56, the side edges 58 of which converge starting from the edge 57 of the web 54, so that the distance of the side edges 58 from the Edge 57 reduced from. 11 is the The angles of the side edges 58 are the same for each cut 56, whereas the upper widths of the cuts 56 are different. It would also be possible to design the inclined course of the side edges 58 differently in the case of a plurality of incisions 56 of a clamping device.

10 and 11 is used so that the removed object is pressed into the respective notch 56 from above in FIGS. 10 and 11 until it is fixed by the clamping action between the side edges 58.

So that the side edges 58, in particular if the web 54 is made of sheet metal, cannot damage the object to be fixed, the invention proposes to bend the side edges 58 of the incisions 56 in one direction, for example to the rear, as shown in FIG. 12. This bending of the side edges 58 can be produced in one operation in the manner of a pull-through when punching the incision 56, so that there is no increased production outlay.

From Fig. 12 it can also be seen that the web 54 is formed by the front legs of an angle profile 59.

Fig. 13 shows on an enlarged scale another way how the risk of damage to the object to be clamped is eliminated. Here, a profile 60 made of plastic is pushed onto the side edges 58 of an incision, which is U-shaped in cross section and encloses the side edges 58. Due to the use of this profile 60, the surface pressure and thus the stress on the object to be clamped is reduced.

While the incisions 56 are shown with parallel side edges in FIG. 10 and with converging rectilinear side edges in FIG. 11, it is also possible and is proposed by the invention that the side edges are, for example, stepwise or may also deviate from a straight line. All these shapes have in common that they can be produced in a simple operation by punching and enable the object to be defined to be inserted laterally.
