Abstract

A joining apparatus magazine temporarily stores a plurality of joining elements loaded from a loading station and feeds the joining elements to a joining head connected to an assembly line robot. The magazine comprises a housing connectable to the joining head; a drive motor; and a rotary body rotatable about an axis by the drive motor. The rotary body includes a plurality of chambers for temporarily storing joining elements. The magazine further comprises a loading arrangement operable for loading joining elements into the chambers; and an unloading arrangement operable for discharging a joining element from the chamber toward the joining head. The loading arrangement and the unloading arrangement are coupled together such that either a chamber can be loaded or a chamber can be unloaded.

First claim

What is claimed is:

1. A magazine for temporarily storing a plurality of joining elements loaded from a loading station and for feeding the joining elements to a joining head connectable to an assembly line robot, the magazine comprising:
a housing connectable to the joining head;
a drive motor;
a rotary body that can be rotated about an axis of rotation by the drive motor, and partially defining a plurality of chambers for temporarily storing joining elements, each of the plurality of chambers is a cylindrical bore circumferentially fully defined by the rotary body and axially parallel with the axis of rotation and includes an axial opening;
a loading arrangement operable for loading joining elements axially into the chambers;
an unloading arrangement operable for discharging a joining element axially from the chambers toward the joining head; and
wherein the loading arrangement and the unloading arrangement are structurally coupled together such that either a chamber can be loaded, or a chamber can be unloaded.

2. A magazine according to claim 1 , wherein the loading arrangement and the unloading arrangement are mechanically coupled so as to implement the alternate loadability or unloadability.

3. A magazine according to claim 1 , wherein at least one of the loading arrangement and the unloading arrangement can be mechanically actuated.

4. A magazine according to claim 3 , wherein the loading arrangement includes a release slide that can move relative to the rotary body between a release position and a closed position, and, when moved towards a loading station, the release slide can be actuated through an opening in the housing by the loading station.

5. A magazine according to claim 1 , wherein the chamber is formed so as to be rotationally symmetrical about a chamber axes that extends in parallel with the axis of rotation.

6. A magazine according to claim 1 , wherein the housing further includes a first fastening device for fastening the housing to the robot, and a second fastening device for fastening the housing to the joining head.

7. A magazine according to claim 1 , wherein the unloading arrangement includes a pivot joint receptacle for receiving, in the manner of a pivot joint, an end of a transfer duct into which a joining element can be unloaded from a chamber and transferred to the joining head.

8. A magazine according to claim 1 , wherein the plurality of chambers includes first chambers and second chambers arranged in different circumferential sectors of the rotary body.

9. A joining apparatus for installing a joining element, the joining apparatus comprising:
a joining head including a holding device for holding the joining element; and
a magazine for temporarily storing a plurality of the joining element that can be transferred individually into the holding device, the magazine including:
a housing connected to the joining head;
a drive motor;
a rotary body that can be rotated about an axis of rotation by the drive motor, and partially defining a plurality of chambers for temporarily storing the joining elements, each of the plurality of chambers is a cylindrical bore circumferentially fully defined by the rotary body and axially parallel with the axis of rotation and includes an axial opening;
a loading arrangement operable for loading the joining elements axially into the chambers;
an unloading arrangement operable for discharging a joining element axially from the chambers toward the joining head; and
wherein the loading arrangement and the unloading arrangement are structurally coupled together such that either a chamber can be loaded or a chamber can be unloaded.

10. A joining apparatus according to claim 9 , and further comprising a robot including an arm connected to a first side of the housing of the magazine, and the joining head is connected to a second side of the housing of the magazine facing away from the arm of the robot.

11. A method for loading joining elements from a loading station into a joining apparatus mounted on a robot and including a joining head, the method comprising the following steps:
a) providing a magazine for temporarily storing a plurality of the joining elements loaded from the loading station and for feeding the joining elements to the joining head, the magazine comprising:
a housing connected to the joining head;
a drive motor;
a rotary body that can be rotated about an axis of rotation by the drive motor, and partially defining a plurality of chambers for temporarily storing joining elements, each of the plurality of chambers is a cylindrical bore circumferentially fully defined by the rotary body and axially parallel with the axis of rotation and includes an axial opening;
a loading arrangement operable for loading joining elements axially into the chambers;
an unloading arrangement operable for discharging a joining element axially from the chambers toward the joining head; and
wherein the loading arrangement and the unloading arrangement are structurally coupled together such that either a chamber can be loaded or a chamber can be unloaded;

b) moving the joining apparatus towards a loading station and actuating the loading arrangement by contacting the loading station to uncover a top of a chamber of the magazine;
c) loading a joining element axially into the uncovered chamber; and
d) moving the joining head away from the loading station.

12. A method according to claim 11 , wherein the plurality of chambers includes first chambers and second chambers arranged in different circumferential sectors of the rotary body, and wherein, in order to unload a first chamber, the rotary body is rotated in a first direction opposite to a second direction for unloading a second chamber.
