Abstract

A driving module for driving fasteners into a workpiece, the fasteners being interconnected via a connection mechanism to form a fastener belt and being magazined and rolled up to form a fastener belt roll, wherein the driving module has a driving apparatus, wherein the driving module has a mounting portion for mounting the driving apparatus on a workpiece bridge, wherein the driving apparatus has a driving drive, which acts on the respective fasteners to be driven with a driving force by way of a driving ram that is displaceable in the driving direction, and wherein a magazine having at least one exit portion is connectable to the driving apparatus; and by way of the exit portion, the fastener belt can be routed out of the magazine, and wherein the magazine has at least one fastening portion for fastening the magazine or parts thereof to the driving apparatus, wherein the magazine has at least two belt roll holders, each for receiving at least one fastener belt roll.

First claim

The invention claimed is:

1. A fastener driving module comprising:
a driving apparatus including a driving drive having a driving punch displaceable in a driving direction to respectively exert a driving forces on each of a plurality of fasteners received from one of two fastener belt rolls, each fastener belt roll including a plurality of fasteners interconnected by a connection mechanism to form a fastener belt that is rolled up to form the fastener belt roll;
a mounting portion configured to mount the driving apparatus to a workpiece bridge; and
a magazine connectable to the driving apparatus, the magazine including first and second fastener belt roll holders that are each configured to hold one of the two fastener belt rolls, the magazine having an exit portion through which the fastener belts can sequentially move out of the magazine, wherein the first and second fastener belt roll holders are each positionable to a dispensing position at which fasteners from the fastener belt roll held by that fastener belt roll holder are dispensable to the driving apparatus, wherein the first fastener belt roll holder is positionable in a first reserve position while the second fastener belt roll holder is positioned in the dispensing position, and wherein the second fastener belt roll holder is positionable in a second different reserve position while the first belt roll holder is positioned in the dispensing position.

2. The driving module of claim 1 , wherein the fastener belt roll holders include magazine cartridges that each has a fastening portion that enables that magazine cartridge to be decoupled from the driving apparatus.

3. The driving module of claim 1 , which includes a magazine-changeover mechanism having a magazine changeover actuator configured to:
cause the first fastener belt roll holder or the second fastener belt roll holders to be positioned in the dispensing position;
cause the first fastener belt roll holder to be positioned in the first reserve position while the second fastener belt roll holder is positioned in the dispensing position; and
cause the second fastener belt roll holder to be positioned in the second reserve position while the first belt roll holder is positioned in the dispensing position.

4. The driving module of claim 1 , which includes an fastener belt feed mechanism and a threading mechanism, wherein the threading mechanism is configured to perform a threading procedure in which the beginning of one of the two fastener belts is transferred to the feed mechanism after the other fastener belt.

5. The driving module of claim 4 , wherein each of the two fastener belt roll holders has a holder configured to hold the beginning of the fastener belt held by that fastener belt roll holder.

6. The driving module of claim 4 , wherein the fastener belt feed mechanism includes: (a) a plurality of feed elements distributed along a feed direction, and (b) a plurality of restraint elements distributed along the feed direction.

7. The driving module of claim 6 , wherein the feed elements and the restraint elements are held on a carrier part, wherein the carrier part is pivotable to make accessible one of the fastener belts when that fastener belt is placed into the feed mechanism.

8. The driving module of claim 1 , which includes an apparatus support, wherein the driving apparatus is disposed on the apparatus support, and wherein the driving apparatus is advanceable toward a workpiece.

9. The driving module of claim 8 , wherein the magazine is coupled to the apparatus support such each of the fastener belt rolls held in the magazine are substantially decoupled from the advancing motion of the driving apparatus.

10. The driving module of claim 9 , wherein the exit portion of the magazine is mounted so as to be displaceable in relation to a fastening portion of the magazine.
