Abstract

PURPOSE:To fill automatically trays into packages before filling of goods by providing a tray deforming bar to curve a tray into a roof shape and a tray transfer rod in which a transfer piece at the rear end transfers a tray and another transfer piece at the front end fills a tray into a bag. CONSTITUTION:A tray (a) is transferred one by one to a rail 1 of a tray supplying part I, to a first supplying position X1 by a pressing plate 3 of a conveyor belt 2, and to a second supplying position X2 of a tray filling part II by air injected from air injection pipes P1 and P2. A transfer piece 33 makes the tray (a) advance which to slide on a slide piece 4a of tray guides 4 on both sides. The guides 4 are bent so as to approach to each other, and a tray deforming rod 26 inclines upward. Therefore the tray (a) is deformed into a roof shape while it passes through the guides 4 and rod 26, and transferred to a position of a precedent tray (a1). Tip ends of tip end guides 11 are inserted into a bag mouth (b), a roll is pushed by a swinging piece and the tip end guides 11 widen so that another transfer piece 34 of a tray transfer rod 32 passes without resistance. The tray (a) is transferred by the transfer piece 34 at the front end of the transfer rod 32 and filled into a bag mouth (b).
