DETAILED DESCRIPTION
(12) The driving module 1 according to FIG. 1a is a driving module 1 for driving interconnected sets of fasteners 100 into a workpiece 200, wherein the fasteners 100 are interconnected by a connecting mechanism, wherein each set of the fasteners 100 are connected to one another to form a fastener belt 102, and each of the fastener belts is rolled up to form belt rolls 101 and 101 that are magazined. The driving module 1 has a driving apparatus 20 and a mounting portion 12 for mounting the driving module 1 on a tool bridge 300. The driving apparatus 20 has a driving drive 21 configured to act with a driving force on the respective fastener 100 to be driven and does so by way of a driving ram 23 that is displaceable in the driving direction indicated by arrow 22 with a driving force. A magazine 30 having at least one exit portion 33 and 33 is fastened to the driving module 1. By way of this exit portion, the fastener belt 102 can be advanced out of the magazine 30 from the belt roll 101. The magazine 30 has at least one fastening portion 32 for fastening the magazine 30 or parts thereof on the driving module 1. The magazine 30 also has two belt roll holders 31 and 31 each for receiving a respective one of the belt rolls 101 and 101. The fasteners here are nails, which are connected to a plastic belt.
(13) The driving module 1 according to FIG. 1b also has an apparatus support 10 in addition to the one from FIG. 1a, and the driving apparatus 20 is arranged on the apparatus support 10. The driving apparatus 20 can be advanced as such by way of an advancing drive 40 to the respective workpiece 200 in an advancing movement. For this purpose, it is guided displaceably by way of an apparatus guide 11 on the apparatus support 10 in the driving direction 22. The magazine 30 is coupled to the apparatus support 10 in such a way that a belt roll 101 inserted into the magazine 30 is essentially decoupled from the advancing movement of the driving apparatus 20. It is not necessary here for the magazine 30 to have at least two belt roll holders 31 and 31, each to accommodate at least one belt roll, but this is very advantageous.
(14) The exemplary embodiment shown in FIGS. 2a to 6c also has in particular the following features.
(15) The belt roll holders 31 and 31 are embodied as magazine cartridges, and each one of the two magazine cartridges has a fastening portion 32 and 32, respectively. They can be decoupled separately from one another from the driving module 1. The driving module 1 has coupling rails 13 and 13 (see FIG. 3a) for cartridges 31 and 31 into which a corresponding coupling rail 36 (see FIG. 4b) of the respective cartridge 31 or 31 is inserted to couple that cartridge 31 or 31. The belt roll holders 31 and 31 are each dispensed to the driving apparatus 20 from the belt rolls 101 and 101 held on the belt roll holders 31 and 31 and can be positioned in a reserve position. The displacement direction required for this is indicated by a double arrow in FIGS. 2a and 2b and is oriented essentially at a right angle to the driving direction indicated by arrow 22. The driving module 1 has a magazine changing mechanism 50 with a pneumatically operated magazine changing actuator 51 (see FIG. 3a), by way of which the belt roll holders 31 and 31 can be positioned in the dispensing position and the reserve position. The driving module 1 also has a feed mechanism 70 for the fastener belt 102 and a threading mechanism 60.
(16) The feed mechanism 60 is equipped to carry out a threading operation, in which the start of the one fastener belts 102 and 102 of the one belt rolls 101 and 101 is transferred from one of the two belt roll holders 31 and 31 into the feed mechanism 70 when the other fastener belts 102 and 102 of the other belt rolls 101 and 101 from the other one of the two belt roll holders 31 and 31 is running short or has been used up.
(17) It can also be seen well in FIG. 3a that in this embodiment the advancing drive 40 is embodied as a wedge drive.
(18) It can be seen well in FIG. 4a that the belt roll holders 31 and 31 have a centering unit 37 with three radially displaceable rolls arranged in a circle, such that the belt roll can be placed rotatably on the rolls. The belt roll holders 31 and 31 also each have a cover which can preferably be locked at different levels on a cover holder 34 in order to be adapted to various nail lengths. The belt roll holders 31 and 31 also each have a spring pre-stressed guide plate 35 that should ensure a proper unwinding of the belt roll. Furthermore, each of the two belt roll holders 31 and 31 has a respective exit portion 33 and 33. These exit portions 33 and 33 each have a holder 33.1 that is prevented from reversing, and into which the start of the fastener belt 102 can be inserted. The holder 33.1 has a snap wedge that can be released manually as the return safety.
(19) It can be seen well in FIGS. 4c and 4d that the exit portions 33 and 33 of the belt roll holders 31 and 31 are mounted, so that they are displaceable with respect to the fastening portions 32 and 32 of the belt roll holders 31 and 31 and are mounted so that they are displaceable in parallel with the advancing movement. This is readily apparent by comparing the two figures.
(20) It can be seen well in FIGS. 5a and 5b that the threading mechanism 60 preferably has an actuator-operated towing hook 61 that is equipped to engage with one of the fasteners 100 at the start of the fastener belt 102 and to pull or push the fastener belt until reaching the end of the previous fastener belt still inserted in the feed mechanism 70. For this purpose, each of the exit portions 33 and 33 of the cartridges 31 and 31 has a groove 38 in the area of the return secured holder 33.1 (see FIG. 4b) through which the hook 61 can engage the fastener 100. The towing hook 61 is mounted on a linear actuator.
(21) It can be seen well in FIGS. 6a through 6c that the feed mechanism 70, which is arranged on the other side of the towing hook 61 (see FIGS. 5a and 5b), has multiple feed elements 71, 71, and 71 distributed along the feed direction and multiple restraint elements 72, 72, and 72 distributed along the feed direction. The feed elements 71, 71, and 71 are spring-mounted snap wedges that can be displaced back and forth in the feed direction by way of a feed actuator 74. The restraint elements 72, 72, and 72 are snap wedges that are stationary with respect to the feed direction and are preferably spring loaded. The mobility of the feed elements 71, 71, and 71 is seen by comparing FIGS. 6a and 6b. The feed elements 71, 71, and 71 and the restraint elements 72, 72, and 72 are held on a carrier part 73, wherein the carrier part is pivotable to make the fastener belt 102 that has been inserted into the feed mechanism 70 accessible or more readily accessible. The entire module shown in FIGS. 6a and 6b can therefore be pivoted out of the way because it is mounted on a hinge. FIG. 6c shows the mounting of the snap wedges 71, 71, and 71, wherein the springs that press the snap wedges outwardly are not shown here.
(22) It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present disclosure, and it is understood that this application is to be limited only by the scope of the claims.
