Description

Retaining system for piece goods

Technical Field

The specific disclosure relates to devices and methods in the field of retention systems for piece goods.

Background

The batch assembly of piece goods cut to length, such as cables, wires, bands, hoses or ropes, can be highly automated, wherein a batch assembly system unwinds and cuts off the piece goods required for a group of piece goods from a magazine reel to the correct length. If necessary, the series assembly system can automatically process the ends of the cut piece goods, for example by removing insulation and/or providing them with plug-in connections or the like.

Such systems are used, for example, in production plants in which a large number of different cables, wires, bands, hoses and/or ropes must be provided for a specific structure, for example a land vehicle, a water vehicle or an aircraft or an electronic product. Typically, the pre-bulk assembled piece goods required for a given organization are assembled into a piece goods group and packaged together. For example, piece goods of the piece goods assembly may fall substantially irregularly in the box from the batch assembly plant, or they may likewise substantially irregularly join together into a coarse bundle.

When a piece goods group has a large number of different piece goods, problems and time losses can occur in further use, since the fitter of the downstream production first has to seek and find the correct piece goods.

Disclosure of Invention

The specific disclosure relates to apparatus and methods with which to improve the handling of pre-batch assembled piece goods.

In a first aspect, the specific disclosure relates to a holding system for piece goods, having a tape and a reel core, wherein the tape can be wound helically around the reel core into a holding reel and the piece goods can be clamped between separate layers of the holding reel. The retention system allows in a very space-saving and efficient manner: individual piece goods groups comprising a plurality of piece goods are stored and transported in a sorted manner. The piece goods clamped together on the holding system in the holding reel are released on unwinding of the tape in the reverse order to the order in which the piece goods have been clamped. This allows piece goods to be sorted already in the order they are needed in the subsequent processing steps when they are assembled in series.

In an advantageous manner, the belt can be at least partially elastic, wherein the belt can in particular have at least one rubber layer. A related specific invention refers to a tape as "at least partially elastic tape" which reversibly deforms in the area of the holder goods when rolled up into a holding roll. However, this is not a mandatory requirement, since the band can also be formed in an irreversibly deformable manner, for example. On the other hand, it is also possible for the belt to be constructed in the form of a toothed belt, in which the piece goods are held between the individual teeth of the rolled-up toothed belt. The belt may have a rubber layer, for example on one or both surfaces, wherein the rubber layer is combined with a more solid belt material, such as a belt or a plastic belt. This results in a good clamping action, wherein the rubber layer is elastically deformed for receiving a clamped piece of goods. The strip however has only a small extensibility in the longitudinal direction, which improves the properties of the retention system.

In an advantageous embodiment, the strip may have a width of between about 1cm and about 15 cm. The width is on the one hand coordinated with the required clamping action and on the other hand the required stability of the holding reel formed with the belt must be taken into account. The width of the belt is coordinated with the respective use, wherein the given width range allows for many different uses for the most different pieces of goods. It is noted, however, that for special use cases, bands whose width lies above or below the given width range may also be advantageous.

In another advantageous embodiment, the strip may have a thickness of between about 1mm to about 10 mm. Said thickness additionally affects the number of pieces of goods that can be gripped in the holding reel. The thickness is selected to match the thickness of the clamped region of the piece goods. The thickness of the belt is coordinated with the respective use, wherein the given thickness range allows for many different uses for the most different pieces of goods. It is to be noted, however, that for special use cases, bands with a thickness above or below the given thickness range are also advantageously possible.

In another advantageous embodiment, the belt may have a length of between about 1m and about 15 m. Longer belts allow for the combination of a larger holding reel and a larger number of pieces of goods. The length of the belt is coordinated with the respective use, wherein the given length range allows for many different uses for the most different pieces of goods. It is noted, however, that for special use cases, bands whose length lies above or below the given length range may also be advantageous.

In an advantageous manner, the belt may be a disposable article. This is advantageous in particular in the case of piece goods which are assembled in bulk and are held by holding reels being packed and brought to another production site. Reuse of the tape may not be economical in such a case, and thus disposables are advantageous.

On the other hand, the belt can advantageously be wound back onto the magazine reel as a multiple use item. This may be suitable, for example, in a closed production cycle. The holding reel provided with the piece goods assembled in series can be simultaneously rewound onto a magazine reel when the piece goods are removed, which is then returned to the series assembly system again and used there for holding a new group of piece goods.

In an advantageous manner, the holding system can have a locking device which locks the holding spool against unwinding. The locking device may, for example, be a tightening strap wound around the holding reel, or it may have a clip or the like which is slipped onto the holding reel. If appropriate, the locking device can also be embodied as an adhesive or as a sealing seam, which secures the outer end of the band to the holding reel.

In an advantageous embodiment, one end of the strip can be designed as a spool core. This minimizes the free individual components. The end of the strip can here be fitted, for example, fixedly on the corresponding reel core or be formed by a projecting profile. If necessary, the end of the tape itself can be used as a winding core in the following manner: the tape is wound from the end into a holding reel without further aids.

In another aspect, the specific disclosure relates to a roll-up unit for piece goods, having a rotatably drivable reel core on which a tape can be wound to a holding reel, wherein during winding each piece of goods can be clamped between separate layers of the holding reel. The roll-up unit is used for the advantageous manufacture of the holding system disclosed herein. The rolling-up unit can be automated to almost any degree, but can also be designed for at least partially manual actuation.

In an advantageous manner, the rolling unit can have a device for the automated insertion of piece goods. In conjunction with an automated batch assembly device, the production of the holding system disclosed here can be carried out completely automatically if necessary.

According to a further advantageous embodiment, the winding-up unit can have means for automated assembly of a new reel core on the winding device and/or for automated arrangement of the ends of the tape for winding on the reel core and/or for automated removal of the wound-up holding reel. In this way, an automated production of a plurality of holding spools each having a piece goods group can be achieved.

In another aspect, the specific disclosure relates to a mass assembly apparatus for piece goods comprising the roll-up unit disclosed herein.

In an advantageous embodiment, the piece goods can be mass-assembled cables, wires, bands, hoses and/or ropes. In general, the piece goods can be essentially any solid or flexible object having a protrudingly elongated shape. The elongated piece goods has an end that can be clamped into the holding reel, wherein the remaining length of the piece goods protrudes loosely from the holding reel.

In another aspect, the particular disclosure is directed to a method for sortingly retaining pieces of goods, wherein each of the pieces of goods is sequentially clamped between separate layers of tape during the helical winding of the tape onto a spool core to form a retention spool.

Drawings

The invention will be explained in more detail below with reference to fig. 1 to 3, which show exemplary, schematic and non-limiting advantageous embodiments of the invention. Herein in the drawings:

FIG. 1 shows a holding system wound to hold a roll;

fig. 2 shows a batch assembly plant comprising a roll-up unit for piece goods in a side view, an

Fig. 3 shows a top view of a batch assembly plant comprising a roll-up unit according to fig. 2.

Detailed Description

Fig. 1 shows a half-sectional view of a holding system 1. The holding system 1 has a reel core 4 around which the tape 3 is wound into a holding reel 5. The holding reel 5 is held together by means of a locking device 9 and is locked against unintentional rolling. The locking device 9 has a strap which is tightened around the circumference of the holding reel 5 with a tightening lock 10 and holds the strap 3 rolled up around the locking device 9 together.

Between the individual turns of the band 3, several piece goods 2 are clamped essentially parallel to the axis of the reel core, wherein in each case one first end of the piece goods protrudes on the upper side of the holding reel. The longer second end of the piece goods 2 protrudes from the holding reel on the opposite side and hangs loose. The piece of goods 2 can be, for example, cut-to-length, mass-assembled cables required for the production process. The cable can be provided with plug contacts or the like at one or both ends, respectively, as necessary depending on the form in which it is required for the production process.

The retention system 1 shown in fig. 1 can be stored in the form shown, for example, in a packaging box, wherein the long ends of the cables are loosely placed into the box.

For use, the locking device 9 of the retaining system 1 is released and the tape 3 is unwound from the retaining reel 5, wherein the piece goods 2 are released in a defined sequence in turn. The unwinding can be carried out, if necessary, in an unwinding device, wherein the belt 3 is kept taut during unwinding in order to ensure that the integrity of the reel 5 is maintained during unwinding and only one piece of goods 2 is released after another piece of goods, respectively, while the remaining pieces of goods 2 remain clamped in the holding reel 5.

Fig. 2 and 3 show a device for producing the holding system 1 shown in fig. 1. The device shown in a side view in fig. 2 is shown in a top view in fig. 3.

The apparatus shown in schematic illustration in fig. 2 and 3 has a roll-up unit 7 and a batch assembly apparatus 8. The mass assembly device 8 may be a fully or semi-automatic device for mass assembly of cables. The cable is unwound from one or more cable drums 11 and cut into pieces 2 of goods in defined lengths. The ends of the piece goods 2 can be processed by the mass assembly device 8 if necessary. For example, the cable end can be de-insulated and/or provided with a plug contact, a crimp sleeve or the like, or the end of the piece goods 2 can be locked against tearing in a known manner.

Above the mass assembly device 8, a magazine reel 6 is arranged, which has a rolled-up tape 3. The cartridge reel 6 is supported on an unwinding bearing 12, wherein the tape 3 can be unwound laterally to the winding-up unit 7.

The winding-up unit 7 has a drive 13 on which the winding core 4 is rotatably arranged. For producing the holding system 1, the free end of the tape 3 unwound from the magazine reel 6 is placed on the reel core 4 and is fixed on the reel core 4, for example by means of a clamping device or by being wound up. During the winding of the band 3 onto the holding reel 5 by the drive 13, into the holding reel 5 thus formed around the reel core 4, the end of the piece goods 2 can now be clamped between the separate layers of the band 3. The belt 3 is loaded with sufficient tensile stress, for example, by means of an unwinding bearing 12 or an additional roller arrangement, so that the winding drum 5 is held sufficiently stationary for good clamping action.

In order to clamp the piece of goods 2, the end of said piece of goods is inserted into the wedge-shaped region between the holding reel 5 and the conveyor belt 3. The tape 3 is then wound further by means of the drive device 13, wherein the end of the piece of goods 2 is clamped between the newly wound part of the tape 3 and the layer of the tape 3 below the newly wound part on the holding reel 5. The batch assembly apparatus may sever and release the other end before, during or after the clamping. The free end of the piece goods 2 can, for example, hang down freely, as is shown in fig. 2, or be inserted into a container, for example a transport container, over a greater length. After the retaining system 1 has been produced with a complete piece goods group of piece goods 2, the strip 3 can be cut off and the ends fixed on the outer circumference of the retaining reel 5, for example by means of gluing or clamping or tensioning devices or in a similar manner. The completed retention system 1 may then be removed from the roll-up unit 7. For example, the holding system 1 can be placed in a transport box, in which the hanging end is already located.

If necessary, the magazine reel 6 can already provide the tape 3 in a suitable length, so that said tape does not have to be cut. Whereby the belt 3 can be reused in the sense of multiple use of the article.

In order to separate the piece goods held together with the holding system 1 disclosed herein, a unrolling device may be used, which may be configured similarly to the rolling unit 7 shown in fig. 2 and 3. In contrast to the wind-up unit 7, however, in the unwinding device the cartridge reel 6 is driven in rotation, wherein the tape 3 is unwound from the holding reel 5 and wound onto the cartridge reel 6. At this point, the piece goods 2 are released again one after the other.

It is noted that the orientation shown in the figures is chosen purely exemplarily. The specific disclosure is not limited to the orientation shown. In particular, instead of the illustrated vertical axes of the holding reel 5 and of the magazine reel 6, an arrangement with a horizontal or inclined axis can also be provided. The structural implementation of such an embodiment is within the abilities of one of ordinary skill in the art in recognition of the teachings disclosed herein.

In the description and claims, the term "substantially" or "approximately" unless stated otherwise means a deviation of up to 10% of the stated value, not only downwards but also upwards if physically possible, otherwise only in the appropriate direction, the specification of degrees (angle and temperature) thus referring to ± 10 °.

The individual features and variants given in the individual embodiments and examples can be freely combined (as long as they are not described in the field, for example, in addition) with the features and variants of the other examples and embodiments and in particular for characterizing the invention in the claims, without the respective embodiments or the further details of the respective examples being combined in a mandatory manner.
