Definitions

  • the invention relates to a device for separating head bolts, such as screws, rivets or the like, which are supplied from an initially disordered supply via an inlet conveyor chute and are aligned in succession. and for distribution in the inlet of several downstream pneumatic conveying lines, in which the head bolts are individually to the intended place of use, e.g.
  • the head bolts from the conveyor chute individually entering an inlet slot with the head pointing upward and then being moved in a distribution slot to vertical discharge chutes by means of a carriage which can be moved transversely to the entry direction, and the pneumatic conveyor lines being connected downstream of them, and the discharge chutes through a cylindrical locking body which passes through them transversely and is aligned with the discharge chutes, each with a transverse bore and can be rotated over a predetermined angular range, into one of the discharge chutes assigned to the respectively assigned and thereby closed against the passage of headed bolts and into one with the associated one Throw chutes in alignment and so the entry of the head bolts into the transverse bores allowing position can be rotated, and for actuating the closure body at one end a lever rotatably is arranged, at the free end of the lever the piston rod of a pressure medium-actuated piston-cylinder unit is connected.
  • the invention has for its object to provide a device which can be used with the same structure either for each of the two applications described.
  • the closure body has a diameter which is greater than the maximum total length of the head bolts to be separated and is mounted in a complementary cylindrical receiving bore in which the vertical discharge chutes open radially , the wall of which is diametrically opposite the mouths of the discharge chutes, however, and that by an angular amount of the order of 90 ° to the mouths of the discharge shafts, a transfer channel connected to one of the downstream pneumatic conveying lines and a diametrically opposite one compressed air duct Access channel opens into the wall of the mounting hole.
  • the head bolts conveyed into the discharge chutes with the shafts pointing forward by the shafts therefore enter the transverse bores without being able to exit at the underside, because the wall of the receiving bore there is closed as required.
  • the piston-cylinder unit is actuated in such a way that the cylindrical closure body is rotated into the other position, the transverse bores are aligned with the mouths of the transfer channels on the one hand and the compressed air access channels on the other, whereupon the headed bolts are caused by sudden Actuation of the compressed air access channels with compressed air into the transfer channels and the connected pneumatic conveying lines and via these to the intended place of use.
  • Head bolts with the head facing forward are thus only required an offset attachment of the lever to the closure body and pressurized air to the piston-cylinder unit in the opposite direction. That the device can be installed according to the required application.
  • the lever provided for rotating the closure body prefferably be detachable and fastened in a rotationally fixed manner in two positions offset by approximately 90 °.
  • the device according to the invention can also be subsequently changed over from one application to the other at any time.
  • the piston-cylinder unit must be dimensioned at least equal to the path required for pivoting the closure body by means of the lever by 90 °. If the working stroke is larger, it can be ensured by means of appropriately adjustable stops for the lever that in each of the two end positions the aligned one Alignment of the cross holes with the discharge chutes or the transition channels is ensured.

  • the separating and distributing device shown in the drawings designated in its entirety by 10, has a first carriage 12 made of a metallic body, which is arranged horizontally displaceably in a frame 14 between two positions.
  • the frame is formed by two outer flat profiles 16, 16 ', which are closed at their upper and lower ends by further flat profiles 18, 20 screwed to the profiles 16, 16'.
  • two horizontal guide rods 22, 22' running parallel to each other are held, on which the slide 12 is mounted so that it can be moved back and forth between the two end positions by means of a pneumatic piston-cylinder unit 24.
  • Four vertical discharge chutes 26 are formed in the carriage 12 at equal intervals in the transverse direction, the diameter of which is dimensioned such that the headed bolts to be separated and distributed can pass through them.
  • the frame 14 is provided with an inlet slot 28 at right angles to the slide displacement direction, through which the head bolts to be separated and distributed on the discharge chutes 26 can enter from an inclined feed conveyor chute (not shown), the inlet slot 28 being approximately equal in width to that The diameter of the bolt shafts is dimensioned so that the overhead headers of the head bolts are supported laterally next to the inlet slot 28 on the profile 18.
  • a transverse distributor slot 30 which extends from the mouth of the inlet slot 28 in opposite directions by approximately the amount of the distance between adjacent discharge chutes 26, i.e. a total of approximately the length of twice the distance of the discharge chutes 26 from each other.
  • the distributor slot is closed off by a recess 31 with an enlarged diameter, through which the heads of the cap screws can pass into the discharge chutes 26, which are respectively aligned below them.
  • Her carriage 12 can be displaced transversely by the distance between two discharge chutes 26, so that either one of the two central discharge chutes 26 can be aligned with the inner end of the inlet slot.
  • a guide slide 22 which is displaceable relative to the slide 12, is also mounted on the guide rods 22, 22 'and engages around the profile 18 on the upper side and the lower side into the area of the distribution slot 30, the profile overlapping the upper side Part of the carriage is formed by a plate 34, which runs two at a distance from two adjacent chutes 26 has slots 36 open on the slot side, into which the heads of the head bolts which have entered via the inlet slot 28 can enter.
  • Receptacle 36 run head bolts in the distribution slot 30 to the nearest discharge chute and is thrown into this, at the same time the second receptacle 36 is aligned with the inlet slot 28 and consequently the next succeeding head bolt enters this receptacle 36. The next time the distributor slide 32 is actuated in the opposite direction, the head bolt which has previously entered the receptacle 36 is then guided into the opposite, adjacent discharge chute 26 and is thrown off there. In this way it is therefore possible to alternately feed two discharge chutes located at twice the distance between adjacent discharge chutes with the head bolt that is to be applied.
  • the discharge chutes 26 do not penetrate the carriage 12 completely, ie they are closed on the underside.
  • a rotary slide-type cylindrical closure body 40 is rotatably inserted over a predetermined angular range of approximately 90 ° in a bore 38 provided in the slide 12 and extending completely through the slide, in each of which, in alignment with the discharge chutes 26

  • the diameter of the closure body is larger than the maximum total length of the head bolts to be separated and the diameter of the transverse bores 42 corresponds to the diameter of the discharge chutes 26, so that the head bolts dropped into the discharge shafts in the stable illustrated in FIG. 3 are aligned with the discharge shafts of the cross bores 42, the thrown-off head bolts lie completely within the quarbores 42.
  • a pin 44 is rotatably attached, which projects laterally from the slide 12, and on which a lever 46 protruding at right angles to the closure body axis of rotation is fastened in a rotationally fixed manner, for example by pinning one on the closure body side
  • a lever 46 protruding at right angles to the closure body axis of rotation
  • the outer end of the piston rod 50 is articulated to a pneumatic piston-cylinder unit 52, the cylinder of which is connected at its end facing away from the piston rod to a holder 54, which in turn is attached to the end section of an elongated flat profile 56, which is in turn attached to the side of the carriage 12 from which the pin 44 protrudes.
  • the piston-cylinder unit 52 is thus firmly connected to the slide 12 and is also moved together with the slide 12 when the piston-cylinder unit 24 is actuated.
  • a crossover channel 58 opens radially in the transverse bore 42 and this diametrically opposite a compressed air access channel 60.

Abstract

Dispositif (10) de triage et de répartition de boulons à têtes tels que des vis, des rivets ou analogue, dans les entrées de plusieurs tubes transporteurs pneumatiques subséquents (62). Les moyens de triage (10) comportent des goulottes de jetée (26) agencées avant l'entrée des tubes transporteurs pneumatiques. Chaque goulotte de jetée (26) est dotée d'un corps de fermeture (40) formé par une vanne rotative commandée pneumatiquement ou hydrauliquement et dotée de trous de positionnement (38), destinés à chaque boulon à tête individuel trié dans la goulotte de jetée correspondante. Les sorties des goulottes de jetée sont décalées d'environ 90° par rapport aux canaux de transition (58) menant aux tubes de transport pneumatiques. Une oscillation à 90° du corps de fermeture permet aux trous de positionnement (38) du corps de fermeture (40) d'être sélectivement alignés avec les goulottes de jetée ou leurs canaux de transition associés (58). Les boulons à tête individuels triés par les goulottes de jetée dans les trous de positionnement peuvent ainsi être transportés jusqu'aux tubes transporteurs subséquents, par les canaux de transition, une fois le corps de fermeture réorienté. Selon le sens de rotation du corps de fermeture lorsqu'il est réorienté, les boulons à tête peuvent être sélectivement transférés dans les tubes transporteurs pneumatiques la tête ou l'extrémité de tige libre la première.
