The hub body (4) has at least two support jaws (6a to 6c) which are designed to at least indirectly grip in an interior a roll of edge tape which can be at least partially slipped onto the hub body. The locking mechanism (11) has an adjustment element (12) which is rotatable in a defined manner about a rotational axis (X) relative to the hub body (4) and at least one arm (13a to 13c) which couples the adjustment element (12) to one of the support jaws (6a to 6 c). The rotational movability of the adjusting element (12) is converted into a linear displacement of the support jaws (6a to 6c) coupled to the arms (13a to 13c) radially relative to the axis of rotation (X).

Description

Accommodating device for edge tape roll

Technical Field

The invention relates to a receiving device for a side tape roll (kantenbandroll) according to the preamble of claim 1.

Background

Furniture panels of wood or wood substitute materials often already have at least one covering surface which is at least partially coated before the reprocessing thereof. The coating types include coverings ranging from lacquers up to layers with solid wood veneer or plastic. In addition to improved appearance and care, the surface-coated furniture panels have increased durability with respect to mechanical action and liquids. Since already coated furniture panels are often cut out, the coating of the narrow sides of the fixture panels is only carried out in a subsequent process. In the case of the so-called edging (bekanten), the edge strip is provided at least partially on the uncoated narrow side of the furniture plate for this purpose. The fastening of the edge strip is usually based on gluing or/and micro-form-locking by local welding.

In the industrial context, the edging of wood material panels takes place by means of edging machines in which the edge bands are treated in a continuous process by means of at least one edging machine. In this case, the edge strips are present in the form of a plurality of rolled-up edge strips, in order to transport and support large lengths reliably, even in the most compact possible manner. For the simplest possible handling, the edge strip can also be arranged in a cassette and can be rolled out of the cassette if required. Depending on the variety of colors and decorations and thicknesses of the furniture plate to be edged, the edge strips must be replaced frequently and for the respectively adapted variants.

Since the edge strip wound into an edge roll shows a natural tendency to uncontrolled unwinding and misalignment between the individual turns of the edge strip, maintenance of the edge strip requires corresponding caution. The support of the edge strip, which can be spread out in a controlled manner, is of increased significance here.

Thus, DE102017125039B3 and DE10125761a1 describe receiving devices for edge roll packets, each of which comprises a hub that is mounted so as to be rotatable about an axis of rotation. In a plane extending perpendicular to the axis of rotation of the hub, a disk element extends, which can be used to laterally support a roll of edge tape that can be received by the hub. The respective hub has at least two support jaws which are designed to at least indirectly grip in an inner side band coil which can be at least partially slipped onto the hub.

The internal clamping enables a precise and reliable support of the edge roll, which is sufficient without additional hold-downs or other safety devices. The movable support jaw produces a radial tensioning of the individual layers of the edge strip wound one on top of the other, which acts in the plane of the edge strip roll, which effectively prevents an otherwise possible misalignment of the edge strip.

The internal clamps known from the prior art require sufficient installation space in order to be able to handle the movable components thereof. This is important in particular when a plurality of such receiving devices are arranged next to one another, for example in each case in connection with a cassette. Such arrangements are often encountered in the industrial edging of wooden panels, many of which are assembled, for example, into racks, cabinets or carts.

Disclosure of Invention

The object of the present invention is to further develop a receiving device as described above such that it has a design for the inner clamping edge roll that is as small as possible.

This object is achieved by a receiving device having the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims.

According to the invention, the receiving device has a locking mechanism with an adjusting element that can be rotated in a defined manner about a rotational axis relative to a hub, in particular supported on a shaft. Furthermore, at least one arm is provided which couples the adjusting element with one of the support jaws. The arrangement and design of the adjusting element and the arm and their cooperation are selected such that the rotationally movable property of the adjusting element is converted into a linear displacement of the support jaw coupled to the arm radially relative to the axis of rotation.

The advantage resulting therefrom is that the movement necessary for the inner clamping takes place completely parallel to the disk element. In other words, no displacement of the components of the receiving device along or parallel to the axis of rotation is required, so that the inner clamping has an extremely slim design. By converting the rotational movability of the adjusting element into a translational displacement of the support jaw coupled to the arm, via the arm, a precisely working inner clamping is produced. The transition may be sufficiently self-locking to maintain the required stress. Possible "slipping" between the rotatable hub and the edge tape roll fitted thereto is thus effectively prevented. By the purely linear displaceability of the at least one support jaw coupled to the arm, no relative movement relative to the edge roll takes place.

According to a particularly preferred embodiment of the basic inventive idea, the at least one linearly displaceable support jaw can be mounted on the hub by means of at least one linear guide. This results in a stable and precise guidance of the support jaw, in particular in the radial direction.

In an advantageous manner, the at least one linearly displaceable supporting jaw can be spring-loaded. The spring loading of the support jaws can be carried out such that the support jaws can be displaced at least partially against the spring loading toward the rotational axis of the hub. In contrast, the displacement of the support jaw away from the axis of rotation can be assisted at least partially by spring loading. In this way it is ensured that: sufficient stress is always provided for the inner clamping, which stress can be reduced, for example, only for the replacement of the edge roll, in contrast to the spring loading, until it is completely cancelled. Thus, even when the coupling between the arm and the adjusting element or/and the support jaw may fail, it is ensured that: the edge roll is reliably held on the hub body in the sense of anti-friction properties.

Preferably, the at least one linearly displaceable support jaw may be supported on the hub via a spring element. The advantages resulting from the spring loading of the support jaws have already been explained in detail before. The arrangement of the spring element between the support jaw and the hub can be carried out in addition to the spring loading described above or can form a solution itself. In each case, the arrangement of the spring element between the hub and the support jaw results in the latter being directly loaded with spring force without requiring maintenance-intensive or/and additional installation space-demanding reversing devices.

Furthermore, the hub and the disk element can be connected to one another in a rotationally fixed manner. The disk element can thereby be used to some extent as an easily graspable bearing for correspondingly actuating the inner clamping of the receiving means via a rotational relative movement with respect to the adjusting element.

Stipulating: the adjusting element may be rotatably supported on a section of the hub. In principle, the adjusting element can be at least partially designed as a ring. In particular in combination with the previously mentioned possible non-relative-rotation connection between the disc element and the hub body, this gives a rotatable support of the adjustment element over a small space.

According to a particularly advantageous embodiment of the receiving device according to the invention, the respective support jaw can have at least two parts. In particular, each of said support jaws may comprise a basic jaw and a widening jaw. The widened jaw can be coupled in a suitable manner, preferably magnetically, to the associated base jaw. By bisecting each support jaw, an extremely flexible use for webbing rolls of different inner diameters results. Thus, by omitting the widening jaws or providing them on the basic jaws, the outer radius of the hub can be adapted in a simple manner to the inner radius of the edge roll to be slipped onto the hub.

Preferably, the hub may have at least three support jaws, the locking mechanism having a number of arms adapted to the number of support jaws. In this case, the arms extend parallel to the disk elements and are each coupled to one of the support jaws and to the adjusting element. By means of the at least three support jaws, precise guidance of the side-band coil is produced, the inner circumference of the side-band coil corresponding to a maximum of one third of the support jaws.

The adjusting element of the receiving device according to the invention can also be mechanically fixed relative to it so as to be rotatable about the axis of rotation. In this way it is ensured that: the inner clamp does not itself suffer from unintentional loosening. The temporary fixing of the adjusting element can preferably be effected by means of a suitable locking device.

The receiving device according to the invention enables an elongated construction, in particular with regard to its locking mechanism.

fig. 2 shows a view of the receiving device of fig. 1 in a first state, rotated through 180 °;

Fig. 4 shows a sectional view of the receiving device.

Detailed Description

Fig. 1 shows a schematic first view of a receiving device 1 according to the invention. The receiving device 1 comprises a disk element 2, which for overview reasons is not shown in its entire radial extension (the missing parts are separated by black-and-white lines). A portion 2a (here designed, by way of example, as a triangle) is situated in the center of the disk element 2, through which portion the shaft 3 extends at least partially. A hub 4 is rotatably supported on the shaft 3 about a rotation axis X. The disk element 2 extending in a plane extending perpendicular to the axis of rotation X is connected here, purely by way of example, via a total of three fastening means 5a to 5c, in a rotationally fixed manner to the hub body 4. In this way, the disc element 2 and the hub 4 can rotate together about the axis of rotation X of the shaft 3.

Around the shaft 3, in the embodiment shown here purely by way of example, a total of three support jaws 6a to 6c are provided, which are mounted on the hub 4 in a linearly movable manner via linear guides 7a to 7 c. Furthermore, each of the support jaws 6a to 6c is additionally supported on the hub 4 via an associated spring element 8a to 8 c. The spring elements 8a to 8c produce a permanent spring loading of the linearly displaceable support jaws 6a to 6c, so that they can be displaced against the spring loading toward the axis of rotation X of the shaft 3 and can be displaced away from the axis of rotation X at least partially by the spring loading.

As can be seen, the support jaws 6a to 6c have a halving in the embodiment shown here purely by way of example, so that each support jaw 6a to 6c comprises a basic jaw 9a to 9c and a widened jaw 10a to 10c coupled to the associated basic jaw 9a to 9 c. By corresponding omission or provision of the widening jaws 10a to 10c, the outer radius of the hub body 4 can be adapted correspondingly to the inner radius of an edge roll, not shown in detail here, which can be slipped onto the hub body 4.

Fig. 2 shows a schematic view of the receiving device 1 from fig. 1 rotated through 180 °. In this illustration, the back side of the disk element 2 is viewed and passes through a portion 2a thereof. In this way, the locking mechanism 11 of the receiving device 1 can be seen, which serves for the desired displacement of the linearly movable support jaws 6a to 6c in order to establish the internal clamping for the edge roll. For this purpose, the locking mechanism 11 has an adjusting element 12 which is rotatably mounted on a section of the hub 4 and which, in the embodiment shown here, purely by way of example has the shape of a ring. The adjusting element 12 is coupled via a total of three arms 13a to 13c to one of the three support jaws 6a to 6 c. By mounting the adjusting element on the hub body 4, the adjusting element 12 can be rotated in a defined manner about the axis of rotation X relative to the hub body.

In the locking state Z1 shown here, the arms 13a to 13c extend parallel to the spring elements 8a to 8c, so that they are correspondingly covered in fig. 1 and cannot be seen in this regard.

Fig. 3 shows the unlocked state Z2 of the locking mechanism 11. It can be seen that: the adjusting element 12 is rotated for this purpose in the counterclockwise direction. Subsequently, the rotary movement of the adjusting element 12 is converted into a linear displacement of the support jaws 6a to 6c coupled with the arms 13a to 13c radially relative to the axis of rotation X, so that said support jaws (to a certain extent in a manner not shown in detail) are slightly retracted from their original annular plane about the shaft 3 or hub 4. The unlocked position Z2 enables the edge roll to be sleeved onto the hub and removed from the hub 4.

In a manner not shown in detail, the receiving device 1 may also have a brake device, for example, by means of which the adjusting element 12 that can be rotated about the axis of rotation X can be fixed.

Fig. 4 shows a sectional view of the receiving device 1 in the plane of the axis of rotation X. Here again the portion 2a provided in the disc element 2 and the shaft 3 extending through this portion are elucidated. It can also be seen that: the hub body 4 is rotatably supported on the shaft 3 via a ball bearing 14. Furthermore, a lever shaft 15b of the total of three lever shafts 15a to 15c can be seen, via which the arms 13a to 13c are each coupled at the end side to one of the support jaws 6a to 6c (in particular its respective base jaw 9a to 9c) in a pivotable manner (see also fig. 1 to 3).
