1416131 Removing neck flash SOVAY & CIE 4 Jan 1974 [5 Jan 1973] 00391/74 Heading B5A The neck flash of hollow synthetic resin articles, e.g. blow-moulded bottles, is cut off progressively after removal from the mould and cooling while the article moves so that the axis of its neck is displaced but kept parallel to its starting position and kept perpendicular to the cutting edge and also rotates-about the axis of its neck whereby the means which removes the completely severed neck flashes also removes articles from which the neck flash has not been completely severed. As shown, Fig. 2, the apparatus comprises a rotating support 2 and a conveyer 3 to supply articles 6 to be deflashed to the device and deliver completely deflashed articles therefrom and a cutter 4. Support 2 carries gripping assemblies 5 each comprising a fixed arm 10 and an arm 12 pivoted thereto carrying wheels 21, 23 respectively at their ends. A third wheel 19 is mounted at the pivot of arm 12 to arm 10 and is rotated to rotate the articles on their axes, all wheels 19, 21, 23 being coplanar. The opposite end of arm 12 carries a wheel 25 following cam track 26 to close and open the gripping assembly around the flash of the article as the support 2 rotates. The rims of wheels 19, 21, 23 may enter grooves (35, Fig. 1, not shown) on the neck flash. Cutter 4 comprises a blade 38 in support 39, adjustable by screws 44 or by jack 45. As the support 2 rotates, wheel 23 is at its maximum distance from wheel 21 when the wheel 25 is between positions A, B, the assembly closing on the article 6 between positions B, C and the article is moved past cutter 38. From C, D the gripper is kept closed to retain the severed flash and incompletely deflashed articles, relasing them between D, A. In an alternative embodiment, the cutter may be a disc knife (46, Fig. 3, not shown) mounted coaxially with wheel 19. |
