Abstract

A supply device with which elements in disordered form, in particular connection elements as bulk elements, are suppliable to a second receiving volume. The supply device includes a first receiving container from which, via an outlet opening, a plurality of elements is deliverable to a second receiving container. The second receiving container may consist of an oscillation feeder. The oscillation energy of the oscillation feeder is specifically transmitted onto the elements, which are stored in the first receiving container. With the help of the transmitted oscillations, elements are transferred from the first receiving container via a transfer zone from the first receiving container into the second receiving container.

First claim

1 . A supply device with which elements in disordered form, in particular connection elements as bulk goods, are suppliable to a second receiving volume, the device having the following features:
a first receiving container which defines a first receiving volume for the disordered elements which is fillable via a first supply opening and drainable via a first outlet opening, a second receiving container which defines the second receiving volume, wherein
the first receiving container with the first receiving volume is arranged at least partly within the second receiving volume),
a bottom of the second receiving container is positioned at a distance to the first outlet opening such that the bottom limits the first receiving volume and a transfer zone is present for disordered elements from the first receiving container into the second receiving container, and wherein
at least the bottom of the second receiving container with regard to the first receiving container is movable such that the disordered elements are dischargeable from the first receiving volume of the first receiving container into the second receiving volume of the second receiving container by means of the movement of the bottom.

2 . The supply device according to claim 1 in which the bottom of the second receiving container is puttable into vibrations by means of a drive in order to discharge the disordered elements out of the first receiving container.

3 . The supply device according to claim 1 in which a first circumferential outer wall of the first receiving container includes, adjacent to the outlet opening, a lateral cutout which defines the transfer zone.

4 . The supply device according to claim 3 in which the bottom of the second receiving container is arranged at such a distance to the outlet opening of the first receiving container that disordered elements are discharged through the lateral cutout, but not through a gap between the first outer wall of the first receiving container and the bottom of the second receiving container.

5 . The supply device according to claim 4 in which the lateral cutout encloses an opening angle range from 90° to 180° with respect to a central longitudinal axis of the first receiving container.

6 . The supply device according to clam 3 in which the lateral cutout is at least partly blocked by a flexible retention device, in particular a flexible brush arrangement or an elastic hose or a curtain, which causes the disordered elements to be supplied in the transfer zone at a decelerated movement from the first receiving container to the second receiving container.

7 . The supply device according to claim 6 in which the flexible retention device is arranged in an adjustable manner regarding its position with respect to the lateral cutout of the first receiving container in order to change a size of a covering of the lateral cutout by the flexible retention device.

8 . The supply device according to claim 1 in which a first circumferential outer wall of the first receiving container is arranged approximately circumferentially evenly spaced at the first outlet opening with respect to the bottom and/or to a second inner wall of the second receiving container whereby a transfer gap for disordered elements from the first receiving container into the second receiving container is determined.

9 . The supply device according to claim 1 in which the first receiving container has an essentially cylindrical shape and the second receiving container is configured as a vibration feeder or vibration spiral feeder.

10 . The supply device according to claim 9 in which the first receiving container is arranged coaxially to the second receiving container.

11 . The supply device according to claim 2 in which a first circumferential outer wall of the first receiving container includes, adjacent to the outlet opening, a lateral cutout which defines the transfer zone.

12 . The supply device according to claim 4 in which the lateral cutout is at least partly blocked by a flexible retention device, in particular a flexible brush arrangement or an elastic hose or a curtain, which causes the disordered elements to be supplied in the transfer zone at a decelerated movement from the first receiving container to the second receiving container.

13 . The supply device according to claim 5 in which the lateral cutout is at least partly blocked by a flexible retention device, in particular a flexible brush arrangement or an elastic hose or a curtain, which causes the disordered elements to be supplied in the transfer zone at a decelerated movement from the first receiving container to the second receiving container.

14 . The supply device according to claim 2 in which a first circumferential outer wall of the first receiving container is arranged approximately circumferentially evenly spaced at the first outlet opening with respect to the bottom and/or to a second inner wall of the second receiving container whereby a transfer gap for disordered elements from the first receiving container into the second receiving container is determined.

15 . The supply device according to claim 2 in which the first receiving container has an essentially cylindrical shape and the second receiving container is configured as a vibration feeder or vibration spiral feeder.

16 . The supply device according to claim 3 in which the first receiving container has an essentially cylindrical shape and the second receiving container is configured as a vibration feeder or vibration spiral feeder.

17 . A manufacturing method for a supply device according to claim 1 which includes the following steps:
a. providing (S 1 ) of a vibration feeder,
b. providing (S 2 ) of a frame construction at least partly above the vibration feeder and
c. fastening (S 3 ) a first receiving container at the frame construction, the container defining a first receiving volume for the disordered elements by a first circumferential outer wall, the first receiving volume being fillable via a first supply opening in the first receiving container and being drainable via a first outlet opening in the first receiving container so that a transfer zone for disordered elements from the first receiving container into the second receiving container is present.

18 . A supply method for a plurality of disordered elements, in particular connection elements as bulk goods, with the help of a supply device according to claim 1 which includes the following steps:
a. supplying (Z 1 ) a plurality of disordered elements into the first receiving volume of the first receiving container,
b. moving (Z 2 ) the second inner wall of the second receiving container with respect to the first receiving container, and
c. discharging (Z 5 ) of disordered elements out of the first receiving container through the transfer zone into the second receiving volume of the second receiving container.

19 . The supply method according to claim 18 with the further step:
relocating (Z 3 ) a brush arrangement which closes at least partly a lateral cutout of the first receiving container.

20 . The supply method according to claim 19 with the further step:
relocating (Z 4 ) the first receiving container with respect to the second inner wall so that a transfer gap is defined between the first and the second receiving container.
