Description

The present invention relates to a band reel assembly for winding and / or unwinding of a material strip, in particular metal strip, according to the preamble of claim 1 (see, for example EP-A-0 391 135 ).

Further tape reeling arrangements are known. For example, goes from the DE 10 2009 029 918 A1 a band reel arrangement, in which a band reel is rotatably arranged in a frame. On the expandable tape reel a coil of a metal strip can be wound or fixed. In order to ensure a slip-free winding and unwinding of the metal strip, compressible rollers that can be pressed against the circumference of the coil are provided, which are each arranged in bearing parts. The bearing parts and pressure rollers are pivotable with the aid of a pressure cylinder to push them more or less strongly against the coil or against the outer turn of the coil. A problem here is that the construction of such a band reel assembly is technically complicated and that the band reel assembly thus constructed is therefore relatively expensive.

The object of the present invention is to provide a band reel assembly that ensures a slip-free winding and unwinding of a metal strip and at the same time is relatively simple, compact and inexpensive.

This object is achieved by a band reel assembly having the features of claim 1. The band reel assembly according to the invention accordingly comprises a band reel rotatably arranged in a frame on which a coil of a material band, in particular a metal band, can be wound up. Furthermore, the band reel assembly according to the invention on pressure rollers, which are pressed against the outer periphery of the coil. The pressure rollers are movable by actuating devices which are arranged outside the region of the longitudinal extension of the tape reel, radially inwardly to the longitudinal axis of the tape reel.

The main advantage of the tape reel assembly according to the invention is that it is relatively simple in construction and therefore comparatively inexpensive to produce in comparison to the previously described, known band reel assembly. While in the known Bandhaspelanordnung the hydraulic actuator for the Bandandruckrollen is arranged in the direction of the longitudinal axis of the tape reel in the region of the length of the tape reel, an essential feature of the present invention is that the pinch rollers of the present tape reel assembly are actuated by an actuator which outside the said length of the tape reel, d. H. that is arranged axially laterally of the band reel. This makes it possible to perform the entire band reel assembly seen in particular in the radial direction of the tape reel extremely compact and slender. In addition, a simple removal of the tape reel from the tape reel assembly in the radial direction upwards or in the direction of the longitudinal axis of the tape reel from the tape reel assembly is made possible.

In a preferred embodiment of the invention, the frame has in the longitudinal direction of the longitudinal axis of the tape reel opposite side wall parts in which the longitudinal axis of the tape reel is rotatably mounted. The actuators are arranged on the side facing away from the band reel sides of the side wall parts. This embodiment advantageously allows a particularly simple and effective arrangement of the actuators on the side wall parts.

Particularly simple and easy to install and inexpensive, the actuators in the form of energy storage, preferably of spring parts on, pull or push the longitudinal axes of the pressure rollers in the direction of the longitudinal axis of the tape reel.

A particularly advantageous storage of the longitudinal axis of the tape reel in the side wall parts is achieved in a development of the invention that seen in the direction of the longitudinal axis of the tape reel in the side wall portions opposite recesses are in which the longitudinal axis of the tape reel is rotatably arranged. The recesses have upwardly facing openings through which the longitudinal axis of the band reel up from the Recesses is removable. By this arrangement, a particularly simple and fast removal of the tape reel is advantageously made possible from the frame.
The longitudinal axis can be mounted friction in two bearing parts, which are held in the recesses, wherein the bearing parts can be removed together with the longitudinal axis of the band reel through the openings to the top.

For structurally particularly simple guidance of the longitudinal axes of the pressure rollers in the side wall portions each radially to the longitudinal axis of the band reel extending guides are provided, which are particularly simple in the form of radially extending guide slots, wherein each two guide slots in the direction of the longitudinal axis of the band reel and a longitudinal axis pick up a pinch roller.

When the actuators are in the form of energy storage devices, preferably in the form of spring members, for ease of mechanical attachment to the sidewall members on the radially inner or outer side of each guide slot, a retaining member, preferably in the form of one over the band winder opposite side of the corresponding side wall part projecting retaining bolt, arranged. The longitudinal axes of the pressure rollers are in each case beyond the tape reel side facing away from the corresponding side wall part, wherein between a holding part and a protruding portion of the longitudinal axis of the pressure roller at least one longitudinal axis of the pressure roller in the direction of the tape reel pulling or pushing spring member is arranged. To allow removal of the tape reel from the frame, the outer ends of the upper guide slots have downwardly extending bends. In these bends, the ends of the longitudinal axes of the upper, protruding into the removal area pinch rollers can be locked to permanently remove the pinch rollers for removing the tape reel during the removal process from the area of the tape reel.

In a particularly advantageous embodiment of the invention, the frame comprises four lateral, vertical post parts, two of which are each connected to a side wall part, and four lower crossbars, with the post parts to the rectangular Frame are connected. It is thereby achieved that the present tape reeling arrangement can be transported in a particularly simple manner when the lifting arms of a forklift or the like are pushed under two mutually opposite transverse struts.

For manual rotation of the tape reel, it is advantageous if at least one, over a side wall part projecting end portion of the longitudinal axis of the tape reel, a handwheel is rotatably fastened.

The frame has in a further advantageous embodiment of the invention above the tape reel on a removable cover, which has the shape of a arranged in the conveying plane of the material strip plate, which is seen in the removal direction of the metal strip precedes a removal opening through which the free end of the material strip of the coil is removable to the outside. Alternatively, the frame above the band reel on a removable cover, which comprises parallel to the longitudinal axis of the band reel extending roller parts, which are spaced apart in the removal direction of the metal strip in the conveying plane of the metal strip, and which is seen in the removal direction of the metal strip preceded by a removal opening, by the free end of the metal strip of the coil can be removed to the outside.

In addition, several such Bandhaspelanordnungen should be combined to form a magazine assembly that allows the storage of multiple coils of metal bands of different shapes and materials. In this case, the tape reels after unwinding of the coils the respective Bandhaspelanordnungen each entnehmar easy and be replaced by coils equipped with tape reels.

In this case, this magazine arrangement comprises a plurality of juxtaposed and / or superimposed Bandhaspelanordnungen, such that the unwound from a coil of a band reel assembly unwinded end of a metal strip seen in the removal direction when turning the band reel of Bandhaspelanordnung each above the coil of a next to the Bandhaspelanordnung arranged further Bandschaspelanordnung provided cover is pushed.

The unwound from the coils of the individual Bandhaspelanordnungen the magazine assembly material or metal bands are each about the them in the removal direction in a series of Bandhaspelanordnungen each upstream Bandhaspelanordnungen when rotating the respective Bandhaspelanordnung without slip to the removal side of the magazine assembly be advanced. The displacement during rotation of the tape reel is made possible by the inherent rigidity of the metal strip. After unwinding a desired length of tape from a coil, the metal strip against the removal direction again without slippage on the coil be wound up.

Furthermore, the invention relates to such a magazine arrangement in which below the band reel of a band reel assembly, a bottom part is arranged, over which the free end of the metal strip of wound on the tape reel of the tape reel assembly coils seen in the removal direction when rotating the tape reel of the tape reel assembly to the bottom part next to the Bandhaspelanordnung arranged further Bandschaspelanordnung is pushed.

According to FIG. 1 The present tape reel assembly 1 essentially comprises a frame 2, a tape reel 3 rotatably supported in the frame 2, and a coil 4 wound from a metal tape 5 on the tape reel 3. It should be noted that the reel 4 can also consist of other material tapes.

The frame 2 comprises two in the longitudinal direction of the band reel assembly 1 opposite, each held on a frame 6 side wall parts 7, in which the longitudinal axis 8 of the band reel 3 is rotatably mounted. For this purpose, bearing parts 10 are preferably arranged on the longitudinal axis 8, which are each preferably held in upwardly opening, circular cutouts 9 of the side wall parts 7 in that an annular circumferential groove 11 of each bearing part 10 surrounds the edge region of the respective cutout 9 of the corresponding side wall 7 overlaps. It should be noted that in the FIG. 1 only the bearing part 10, the circumferential groove 11 and the cutout 9 of the front side wall part 7 are shown. The corresponding elements of the rear side wall part 7 are formed accordingly. In this way, it is ensured that the band reel 3 together with the bearing parts 10 and the longitudinal axis 8 can be lifted out of the cutouts 9 upwards, for example, manually out of the frame 2.

In the following, a preferred actuator for actuating the pinch rollers 14 of the present tape reel assembly 1 is explained in more detail. In the side wall parts 7 are in this case opposite to the longitudinal axis 8 extending guide slots 12 are arranged, in which the respective longitudinal axes 13 of the pressure rollers 14 are slidably held. In this way, it is ensured that the pressure rollers 14 can each be moved radially inward from the outside, such that they rest against the outer circumference of the coil 4 arranged on the band reel 3.

In the side wall parts 7 a plurality, preferably six guide slots 12 are provided, of which each two opposite in the longitudinal direction of the tape reel 2. In this way it is ensured that in each case a pressure roller 14 is held radially displaceable in a pair of longitudinally opposite guide slots 12 of the two side wall parts 7. Each longitudinal axis 13 projects with its end regions beyond its associated side wall parts 7 outwards to the sides facing away from the pressure roller 14.

Each longitudinal axis 13 is preferably associated along a imaginary extension of the corresponding guide slot 12 radially inwardly a retaining bolt 15, which is fixed in the corresponding side wall part 7 and protrudes to the tape reel 3 opposite side of the side wall part 7 to the outside.

Since arranged in the guide slots 12 longitudinal axes 13 of the pressure rollers 14 also project outwardly beyond the side wall portion 7, between each a retaining pin 15 and a projecting portion of the longitudinal axis 13 of a pinch roller 14 at least one spring member 16 are arranged in the form of a tension spring, so the protruding portions associated with a pinch roller 14 are pulled radially inwardly through the spring members 16 in the corresponding guide slots 12, such that the pinch roller 14 is pulled against the outer periphery of the coil 4. Preferably, such retaining bolts 15 and spring parts 16 are each arranged on the opposite side wall parts 7. According to FIG. 1 is between a retaining bolt 15 and an end portion of a longitudinal axis 13 each have a schematically illustrated spring member 16 is arranged.
In order to obtain greater spring forces, but also several, z. B. two spring parts connected in parallel and between the corresponding retaining pin 15 and protruding portions of the longitudinal axes 13 may be arranged.

Other embodiments of the spring parts are conceivable. For example, the illustrated retaining bolts may be arranged radially outside the longitudinal axes of the pressure rollers, which is then not in the spring parts to tension springs, but to compression springs. Instead of the spring parts and other energy storage are conceivable.

In the from the FIG. 1 As can be seen, a handwheel 17 can be pushed in a rotationally fixed manner to at least one end of the longitudinal axis 8 of the band reel 3 that projects beyond a side wall part 7, so that the band reel 3 can be turned manually.

Through this removal opening 18, the free end 24 of the unwound from the coil 4 metal strip 5 can be removed. The removal opening 18 joins in the removal direction 25 of the metal strip 5 as seen in a plate-shaped cover member 19, which is part of a cover unit 30 which is detachably arranged on the upper side of the frame 2. For example, the cover unit 30 rests on angle parts 29, which are fastened to the frame 2. On the lower side opposite the cover unit 30, a plate-shaped bottom part 26, which closes the space below the lower pressure rollers 14 downwards, is preferably arranged on the frame 2 and underneath the band reel 3.

In the from the FIGS. 1 and 2 apparent way, the tape reel 3, z. B. after unwinding of the metal strip 5 and after the removal of the cover unit 30, are lifted up from the frame 2. For this purpose, the cutouts 9 in the side wall parts 7 are opened upward in the manner already mentioned, such that the longitudinal axis 8 can preferably be removed together with the bearing parts 10 from the cutouts 9. The upper openings of the cutouts 9 are larger than the diameter of the bottoms of the circumferential grooves 11 of the bearing parts 10.

To make it possible for the tape reel 3 to be removed from the frame 2, the upper pinch rollers 14 can be moved completely out of the area of the tape reel 3 against the force of the spring parts 16, at least one of the guide slots 12 assigned to these upper pinch rollers 14 has the opposite one Side wall parts 7 a from the outer end of the guide slot 12 extending downward bending region 31, in which the over the side wall portions 7 protruding free end portions of the longitudinal axes 13 of the upper pinch rollers 14 from the guide slot 12 are movable downwards and locked. Other locking devices for the longitudinal axes 13 of said longitudinal axes 13 are conceivable.

The function of this roller member 21 will be explained in more detail below. It is also conceivable that explained cover member 19 by perpendicular to the longitudinal axis 8 from each other spaced, rotatably mounted on the Cover unit 30 to replace arranged roll parts whose longitudinal axes are parallel to the longitudinal axis 8.

The expediently rectangular frame 6 has on each side preferably two upwardly and upwardly projecting post parts 22, wherein the upper ends of the post parts 22 each have receiving parts 23 in which the lower ends of the post parts 22 '(FIG. FIG. 3 ) of a further frame 2 'of another band reel assembly 1' can be used, which can be arranged above the lower band reel assembly 1. The said post parts 22 project respectively downwards over transverse struts 28 fastened to them, so that for raising, lowering and transporting the band reel assembly 1 under the transverse struts 22 opposite the longitudinal axis 8 and extending transversely to the longitudinal axis 8, for example the lifting arms of a forklift or another lifting device can be inserted. The already mentioned bottom plate 26 rests on the cross struts 26 or is fixed or integrally connected thereto.

It can according to FIG. 3 Advantageously, a plurality of lower band reel assemblies 1 and upper Bandhaspelanordungen 1 'in rows next to and above each other are arranged. In each case, a Bandhaspelanordnung 1 is arranged below a Bandhaspelanordnung 1 ', the lower ends of their post parts 22' engage in the receiving parts 23 of the lower band reel assembly 1. It is in the in the FIG. 3 apparent above the Bandhaspelanordnungen 1, a removal channel 27 formed by seen in the removal direction 25, each unwound from the coil 4 a rear band reel assembly 1 metal strip 5 can be pushed by turning the band reel 3 to each of the removal direction 25 next front Bandhaspelanordnung 1. In this case, the free end 24 of the metal strip 5 and the subsequent region of the unwound by the coil 4 metal strip 5 due to the inherent stiffness of the metal strip 5 automatically over the roller members 21 and cover 19 of the successive Bandhaspelanordnungen 1 moved forward until the free end 24 of the metal strip. 5 arrives at the end of the row of Bandhaspelanordnungen 1. The pressure rollers 14 press against the coil 4. With a cross cutter or the like, a desired end region can then be cut off from the metal strip 5 for further processing. After cutting can be done by turning the tape reel. 3 in the opposite direction, the metal strip 5 is again pulled back through the removal channel 27 and wound onto the corresponding coil 4, wherein the pressure rollers 14 press against the coil 4.

In the from the FIG. 3 As can be seen, a metal band 5 'of an upper band reel assembly 1' can be unwound from the coil 4 'by rotating the band reel 3' so that it slides below the band reel 3 'due to its inherent rigidity over the bottom part 26' in the withdrawal direction 25 and subsequently over the Bottom part 26 'of each adjacent in the removal direction 25 Bandhaspelanordnung 1' is pushed. One advantage is that both the metal strip 5 'removed from an upper band reel assembly 1' and the metal band 5 taken from a lower band reel assembly 1 are transported substantially to a plane in which the respective processing takes place. Details of FIG. 3 already related to the FIGS. 1 and 2 are explained in the appropriate way.

It is conceivable to arrange further rows of Bendhaspelanordnungen in the manner described above the said upper row of Bandhaspelanordnungen 1 '.

When a tape reel assembly 1 or 1 'is empty, it can be lifted with the aid of a lifter and pulled out of the corresponding row of tape reel assemblies 1, 1'. In its place, then, if necessary, after the lowering of an upper band reel assembly 1 'down, a full Bandschaspelanordnung be used with the lifter.

The following will be related to the FIG. 4 a development of the invention explained in which the band reel 3 and the coil 4, preferably introduced together with the side wall parts 7 and the pinch rollers 14 and the spring parts 16 and the corresponding actuators, in the direction of the longitudinal axis 8 of the band reel 3 in the frame 2 or is taken from this. As a result, a particularly simple insertion of a coil 4 is made possible because of the special construction of the present tape reeling arrangement with the laterally arranged spring parts 16.
