TECHNICAL FIELD

The present invention relates to a device for storing and for supplying balancing weights to a balancing system preferably for balancing of vehicle wheels.

BACKGROUND

Devices for storing and for balancing weights to a balancing system are often used in the production of cars. So-called endless carrier belts are equipped with the balancing weights and packed into package containers from where they are taken continuously at the location of their use, i.e. at the balancing system, and are supplied to said system. A relevant problem is the problem of packing of the carrier belts (which are equipped with the balancing weights) in the most compact manner in order to enable space-saving storage on the one hand and compact configuration of the storage and feed device on the other hand.

In a first embodiment, the balancing weights are arranged on a tape which is adhesive on both sides and is protected on the bottom side by a peel-off strip; this tape forms the carrier belt. In the balancing system, the balancing weights are severed together with the associated tape section and glued onto the component to be balanced after removal of the protective strip. In another embodiment, the balancing weights are arranged on and fixed to a separate carrier belt, which belt is either reusable or is disposed after removal of the balancing weights.

The European patent application publication EP 1 245 940 A2 discloses balancing weights arranged in a comparatively tight packing on a tape that is adhesive on both sides. In order to enable the attachment of a balancing weight (which may be formed by one or several individual weights) to the curved inside or outside of the edge of a wheel rim, the tape used as the carrier belt is slightly elastic to facilitate the adjustment of the distance between the individual weights required to accommodate the curvature of the wheel rim. The ways of storing the so-structured tape are very limited: this embodiment can be stored only in a manner that the tape equipped with the balancing weights is wound on a coil with the balancing weights on the outside. Due to the circular shape of the coil, space-saving storage, space-saving transport and compact configuration of the feed device is complicated and difficult.

SUMMARY

The embodiments of the invention are directed to a device for storing and for supplying balancing weights to a balancing system, which allows space-saving packing and compact configuration of a carrier belt equipped with the balancing weights.

In a first embodiment, a device for storing balancing weights and for administering said weights to a balancing system, includes a carrier belt element which is flexible at least in a main plane directed to accommodate balancing weights. The term “main plane” designates the plane in which the carrier belt is pivoted and/or folded. The balancing weights are arranged sequentially along the longitudinal direction of the belt element. The carrier belt element includes a hinging means or hinge-like arrangement between two belt sections provided for accommodating a balancing weight, said hinge arrangement being pivotable in the main plane in first and second directions and permitting the belt element to fold back onto itself.

The folding back to itself requires bending of the belt element by substantially 180 degrees. This can either be realized in the manner that each hinging means allows for bending by 180 degrees, or that the overall bending span of 180 degrees is achieved aggregately, by having each of two or more of the hinging means provide for bending of the belt at an angle that is smaller than 180 degrees, thereby distributing the bending among two or more hinging means.

The embodiments preferably allow for accommodating a carrier belt equipped with balancing weights in compact zigzag layers, so that it can be packed into a cuboid container, which allows space-saving storage and a more compact configuration of the feed device. The term “main plane” designates the plane in which the carrier belt is pivoted or folded.

In an embodiment, the carrier belt is arranged as a flat flexible tape in a main plane that is disposed transversely and, in a specific case, substantially perpendicularly to the tape plane. The belt element is equipped with a loop for accommodating a balancing weight between two respective tape sections on the tape which are used as hinge arrangements. To remove the balancing weight element, the element can be detached from the loop or the loop can be destroyed. The loop can be arranged as a tape loop formed by a bottom tape and an upper tape. According to another embodiment, the loop is arranged from one or several adjacent cords which are plaited in the longitudinal direction into the tape.

In its common form, a balancing weight element is provided with a notch for accommodating a mounting clamp or clip. In this case, the embodiment provides that the loops will respectively engage in such notches so that the balancing weights on the associated carrier belt will additionally be held in an interlocked manner.

In accordance with another embodiment, the carrier belt element includes at least one strand of pockets, which are arranged behind one another and are connected with one another with flexible connectors such as flexible cords, foe example, to accommodate a respective end of an associated balancing weight. The pockets are dimensioned in such a way that they tightly enclose and hold the ends of the balancing weights. Especially secure holding of the balancing weights is further achieved when both ends of the balancing weights are assigned to such a strand as shown in the embodiment.

A specific type of balancing weights are provided with at least one through-hole which penetrates the balancing weight. In a further embodiment, the carrier belt element is formed by respective cords which are threaded continuously through the through-holes of the successively arranged balancing weights. The threading of the cords through the through-holes is fashioned in such a way that the balancing weights are prevented from slipping along the cords in the longitudinal direction. In accordance with another embodiment, formatted for use with balancing weights having at least one through-hole, the carrier belt is structured as a flat flexible tape is disposed in a main plane perpendicularly to the tape plane and including holding pins. The holding pins are respectively associated with the through-holes of the balancing weights and disposed perpendicularly to the tape plane. The holding pins are dimensioned to securely hold the balancing weights by clamping and/or by means of enlargements formed on the holding pins.

According to a further embodiment, the carrier belt includes clamps which are arranged consecutively (one behind one another), are connected with one another in an articulated manner, include wire(s) and respectively include a clamp bracket holding an associated balancing weight. In the event that the balancing weights are provided with one or several through-holes, each of the clamps may include a holding projection and/or a holding indent which engages with the associated through-hole to additionally secure the balancing weight.

DETAILED DESCRIPTION

FIG. 1 shows a device according to a first embodiment. The carrier belt 2 as shown here contains a plurality of clamps 4, 6, which are arranged behind one another and are preferably made of a resilient wire material. Each of clamps 4, 6 forms (i) a front belt section 10 dimensioned to accommodate a corresponding balancing weight 8 and (ii) a hinge arrangement 12 which cooperates with a subsequent clamp and which allows the carrier belt 2 to bend in the main plane. The main plane is designated with reference numeral 14; the two-directional bending of the carrier belt element 2 is indicated by a double arrow 16. This allows the carrier belt 2 to be folded back onto itself in both directions, and the folded carrier belt can be stored in a zigzag folding manner in an receiving container, for example a cuboid container or a container that is a rectangular parallelepiped. If the hinge arrangement is structured to facilitate bending by up to 180 degrees, the folding-back of the carrier belt can occur in one step, i.e. by way of one single hinge arrangement. It is also possible that the hinge arrangement only allows bending of the belt at a smaller angle such as 90 degrees for example, so that the folding-back of the belt will be distributed among two following hinge arrangements etc. As shown in FIG. 1, each of the clamps 4, 6 includes in the front region a clamping bracket 18 that engages the balancing weight 8 over its edge and holds said weight. Each of the clamps 4, 6 additionally includes in the rear region two outwardly bent hinge pins 20, 22, which engage the respectively associated hinge eyes 24, 26 of next, following clamp and thereby form the hinge arrangement 12.

FIG. 2 shows a flexible tape 30 which forms a carrier belt 28, is disposed in a main plane that is substantially perpendicularly to the tape plane, and includes tape sections 32 (structured as hinging means) and tape loops 34 (formed between two immediately consecutive hinging means) to accommodate balancing weights 36. The balancing weights 36 can be introduced into the tape loops 34 in the direction of arrow 38. In order to remove the balancing weights 36 from the loops, the weights are either pulled laterally out of the tape loops 34, or the tape loops 34 are destroyed so as to release the balancing weights 36. The balancing weights 36 are illustrated in this case by way of example as weights with a middle notch 40 dimensioned to accommodate a mounting clamp that affixes to a wheel rim. It is understood however that especially in the embodiments according to FIGS. 1 to 5 it is also possible to use any other form of balancing weights, e.g. generally known self-adhesive balancing weights of the type as designated with reference numeral 41.

FIG. 3 shows a carrier belt 28 according to the embodiment of FIG. 2 with several balancing weights 36 already inserted into the tape loops. As shown in FIGS. 2 and 3, the balancing weights 36 are respectively provided with a central notch 40 for accommodating a mounting clamp, with the tape loops 34 engaging these notches 40 of the mounted balancing weights 36 to ensure operationally strong lateral hold of the weights.

FIG. 4 shows a carrier belt 42 similar to the one of FIG. 3, with cord loops 44 for holding the balancing weights 46 being formed from two adjacently disposed cords 50 which are plaited in the longitudinal direction into the tape 48.

FIG. 5 shows a carrier belt 52 which includes two strands of successively arranged pockets 56 connected with each other by flexible connectors 54 such as cords, for example, to accommodate the respective end of an associated balancing weight 58. As already explained above, the pockets 56 are dimensioned in such a way that they tightly enclose the ends of the balancing weights 58 and securely hold the same.

FIG. 6 shows a carrier belt 60 which is formed by cords 66 which are threaded continuously through through-holes 62 of the successively arranged balancing weights 64. In order to ensure that the balancing weights 64 are unable to displace in the longitudinal direction, the cords 66 engage into each other within the through-holes 62 in the manner of a machine seam, i.e. the bottom one of the cords engages in a loop of the upper cord.

FIG. 7 shows a carrier belt 68 especially for balancing weights 72 which are provided with through-holes 70. The carrier belt 68 is arranged as a flat tape 74 with holding pins 76 which respectively engage into the through holes 70 and are disposed perpendicularly to the tape plane. The holding pins 76 are dimensioned to engage the through-holes with tight fit and can thereby securely hold the balancing weights 72. As is shown in FIG. 7, the holding pins 76 can contain slits and be provided with enlargement at the ends, so that the balancing weights 72 can be clipped onto said pins.

FIG. 8 shows a schematic side view of two containers 78, 80 which are arranged behind one another and in which one respective carrier belt 82 and 84 is housed in zigzag folding enabled by the hinge arrangement as described above. The front end of the rear carrier belt 84 is suitably connected with the rear end of the front carrier belt 82, so that the carrier belts 82 and 84 can be supplied to the balancing system (not shown) without any standstill caused by a change of tape. In the embodiment according to FIG. 1, the connection of a carrier belt with the subsequent one simply occurs in such a way that the hinge pins 22 of a preceding clamp are introduced by lateral compression of said pin into the hinge eyes 26 of a subsequent clamp, so that this produces a connection with a hinge arrangement between the successive carrier belts.
