Definitions

• the invention relates to a method for Kal ⁇ th of metal strips, the same time delivered from a cutting device, held substantially in their dispensing position and passed by dropping to a winningein ⁇ direction. Furthermore, the invention relates to a corresponding device and an angle shear, in which the method or the device is provided.
• the turnstiles must be aligned very exactly parallel to hold the Blechstrei ⁇ fen and release. Each time the strip width is adjusted, the rotating rods must also be adjusted, and their parallelism must be checked and adjusted, which is expensive.
• the invention has the object to avoid these disadvantages.
• the strips are held magnetically and / or by negative pressure at its top, eliminating the need to align the bracket exactly parallel to the sheet metal strip edges; it is sufficient if the holder engages on the respective sheet metal surface so that the respective sheet metal can be held until it has dropped, essentially in its discharge position in which it has escaped from the cutting device.
• the dropping is then carried out in a simple manner by deactivating the electromagnetic Festhal ⁇ least and / or by mechanical action on the sheet to overcome a permanent magnetic holding force or by deactivating the negative pressure by which the sheet is held on a mating surface.
• the holding preferably takes place electromagnetically and by means of rollers on which the respective metal sheet moves along with its upper side as it emerges from the cutting device.
• Magnetic slidings in particular with a coating which reduces the sliding friction for the sheet, are also preferred.
• suction In the pneumatic support by means of negative pressure surfaces are preferred with suction and with the sliding friction herabsetz ⁇ the coating.
• a stationary holder also the rollers are stationary, since their roller axes are stationary

• the present invention now relates to the holding of the individual metal strips, or a Garvor- direction 10 or 10 'or 10 ", which simultaneously leave the first cutter 2 and held above this before their delivery to the conveyor 14 be, so that an orderly delivery to the För ⁇ derurban results.
• the sheet-metal strips are held in the prior art, to which reference may again be made to the abovementioned Italian type, by specially shaped rotating rods on which the sheet-metal strips rest with the edge regions of their underside. As already explained in the introduction, these rotating rods are rotated in order to cause the sheet metal strips to fall on a delivery of the conveying means, from which deposit the sheet metal strips are gripped by the conveying means and conveyed to the cutting device 3.
• the present invention relates to receiving and holding the metal strips 21-24 during and after the delivery of the metal strips by the cutting device.
• the sheet metal strips are held on their upper side and preferably only on their upper side, so that no holding elements act on the sheet metal strips on the underside.
• auxiliary elements are also provided which additionally support the metal strips, for example on the front side, on their underside and are each pulled away for dropping the metal strips.
• the Hal ⁇ th at the top of the sheets is carried out magnetically and / or pneumatically by negative pressure.
• FIG. 2 shows how the sheet 21 leaves the cutting device in the direction of the arrow A and travels along the rollers 6a-6e, wherein the sheet has already reached the rollers 6a, 6b and 6c in the position of FIG. Due to the magnetic action of the magnetic rollers, the sheet is held by the rollers in its dispensing position above the tray 13 of the conveyor. Become. Permanent magnetic rollers used, so must the dropping of the respective sheet 21-24 in the direction of arrow B by the jewei- 1, are caused by a mechanical Turkwin ⁇ the holding force of the rollers.
• the rollers could be moved upwards into the only indicated roller carrier 5, so that the rollers are lifted off the respective sheet, which is held back by the roller carrier 5 or non-magnetic projections arranged thereon, so that it prevents the movement of the roller carriers Rolls 5 can not join up.
• the rollers are electromagnetically activatable, so that magnetically holding the metal strips on the rollers can be brought about by switching on the current generating the magnetic field, and by dropping off the current, the metal sheet falls down Aufla ⁇ ge 13 is effected.
