摘要:
A nailing machine for assembling pallets made of wood or the like, with sliders for sets of blocks at a variable distance, comprising a substantially horizontal supporting surface (5) for the blocks (54) to be assembled below a corresponding lid (51) to provide a pallet (50) and means (8) for the advancement of the blocks (54) on the supporting surface (5) along an advancement direction (9). The advancement means (8) comprise three pairs of chains (10a, 10b, 11a, 11b, 12a, 12b), which are arranged so that one of their portions is parallel to the advancement direction (9), and sliders (13, 14, 15) are connected to each one of the pairs of chains (10a, 10b, 11a, 11b, 12a, 12b), are arranged at right angles to the advancement direction (9) and are mutually spaced. Each pair of chains (10a, 10b, 11a, 11b, 12a, 12b) engages at least one corresponding pair of actuation pinions (16a, 16b, 17a, 17b, 18a, 18b), which are mutually coaxial and can be actuated with a rotary motion about their corresponding axis and with at least one pair of mutually coaxial guiding pinions. The pairs of actuation pinions (16a, 16b, 17a, 17b, 18a, 18b) are arranged coaxially on a same main shaft (19). Each pair of actuation pinions (16a, 16b, 17a, 17b, 18a, 18b) is connected to a corresponding actuation motor or gearmotor (20, 21, 22) and at least two (17a, 17b, 18a, 18b) of the pairs of actuation pinions (16a, 16b, 17a, 17b, 18a, 18b) are supported by the main shaft (19) freely about their own axis (23). The pairs of actuation pinions (16a, 16b, 17a, 17b, 18a, 18b) can be actuated with identical rotation rates about their own axis (23) for the joint advancement of the sliders (13, 14, 15) connected to the several pairs of chains (10a, 10b, 11a, 11b, 12a, 12b) along the advancement direction (9) or with different rotation rates in order to vary the distance between the sliders (13, 14, 15) connected to different pairs of chains (10a, 10b, 11a, 11b, 12a, 12b).

The present invention discloses a feeding device, a feed channel, and a placing device that is used in conjunction with these special devices. The feeding device utilizes either a strip magazine 10, or a rotational magazine 20. The feeding of the fastening elements is carried out incrementally by means of a movable carriage 30, while simultaneous loading and unloading of the rotational magazine 20 is ensured at different positions during the use of the rotational magazine 20.
摘要:
A self-piercing pin (10, 10a, 10b) and method of installing same. The pin (10, 10a, 10b) includes a body portion (12), a pierce ring (16), a flange (24), and a lock groove (26) which is disposed between the pierce ring (16) and the flange (24). An angled surface (28) is provided between the pierce ring (16) and the lock groove (26). A top side (32) of the flange (24) is generally flat so that the flange (24) can be set flush to the workpiece (18), and to enhance the side load strength of the pin (10, 10a, 10b) once the pin (10, 10a, 10b) is installed. A bottom side (34) of the flange (24) is beveled, angled or flat, thereby minimizing the amount of workpiece material which becomes displaced during installation. Upon installation, the pierce ring (16) shears the workpiece (18), and the material of workpiece flows to the lock groove portion (26) of the pin (10, 10a, 10b), thereby forming a mechanical lock between the pin (10, 10a, 10b) and the workpiece (18). A driver (60) and a die (40) are used to install the pin (10, 10a, 10b).

Die Heftmaschine (1) weist wenigstens einen Heftkopf (3) auf, der beim Heften jeweils mit einem in einem Sammelhefter geförderten Druckprodukt (2,2') mitläuft. Der eine Heftkopf (3) wird nach dem Setzen einer ersten Klammer (5) relativ zu diesem Druckprodukt (2,2') verschoben und setzt an diesem Druckprodukt (2,2') wenigstens eine zweite Klammer (6). Der Heftkopf (3) weist einen Treiber (10) und einen Bieger (11) auf, wobei der Treiber (10) und/oder der Bieger (11) jeweils mit einem steuerbaren Motor (M1,M2) angetrieben ist bzw. sind. Mit lediglich einem Heftkopf (3) können an einem Druckprodukt (2,2') mehrere Klammern (5,6) gesetzt werden. Die Heftmaschine (1) kann mit weniger Teilen realisiert werden und ermöglicht ein einfacheres Umrüsten.
摘要:
A slide guide shaft (4) is formed with a positioning groove (16), and the lever (15) of a driver unit (1) is engaged in the positioning groove to position the driver unit. The positioning pin (10) of a clincher unit (2) is engaged in a pin hole (13) in a slide guide table (3) to position the clincher unit, while a connecting pin (9) engageable with the driver unit is installed and the positioning pin and the connecting pin are driven by a cam plate (12). Turning the cam plate through 180 degrees results in the positioning pin (10) coming off the pin hole (13) to allow the clincher unit (2) to move, and in the connecting pin (9) engaging the driver unit (1), so that the clincher unit and the driver unit are connected together and integrally travel.
