Abstract

ABSTRACT

The invention relates to an apparatus for the filling with a free-flowing product, more particularly a liquid, of a folding box container (4) closed at one end, more particularly at an end equipped with a pouring means or a closure, and for the closing of the containers (4) at the other end, the apparatus comprising an endless conveyor (12) rotating in a vertical plane and having outwardly open compartments into which the containers (4) can be introduced with their ends open in the outward direction by a preceding transfer unit (13), the endless conveyor (12) conveying the containers (4) in steps below a fixed periodically opening product outlet (18) disposed in the upper zone of the conveyor, and from the product outlet (18) to fixed closure elements (19) disposed in said upper zone, and thereafter to an outlet station (23) which is disposed in the lower zone of the conveyor and which lowers the compartments (4) from the compartments by means of removal and transfer elements (23a) and transfers the containers to a removal conveyor (24).

Claims (6)

1. An apparatus for the filling with a free-flowing product, more particularly a liquid, of a folding box container (4) closed at one end, more particularly at an end equipped with a pouring means or a closure, and for the closing of the containers (4) at the other end, the apparatus comprising and endless conveyor (12) rotating in a vertical plane and having outwardly open compartments into which the containers (4) can be introduced with their ends open in the outward direction by a preceding transfer unit (13), the endless conveyor (12) conveying the containers (4) in steps below a fixed periodically opening product outlet (18) disposed in the upper zone of the conveyor, and from the product outlet (18) to fixed closure elements (19) disposed in said upper zone, and thereafter to an outlet station (23) which is disposed in the lower zone of the conveyor and which lowers the compartments (4) from the compartments by means of removal and transfer elements (23a) and transfers the containers to a removal conveyor (24), characterized in that the endless conveyor (12) takes the form of a compartmented wheel at whose upper vertex the product outlet (18) for the direct filling of the containers (4) retain in the compartments of the compartmented wheel is disposed, and each compartment (2) has compartment walls (12a', 12a") which are disposed in succession in the direction of rotation of the compartmented wheel and of which at least one wall (12a') is adjustable in relation to the other wall (12a").

An apparatus according to claim 1, characterized in that the compartment wall (12a') which leads in the direction of rotation of the compartmented wheel is adjustable.

3. An apparatus according to claims 1 or 2, characterized in that the conveyor (12) has two identical compartmented wheels (12a, 12b) which are disposed parallel one beside the other and into whose compartments the arriving containers (4) are pushed alternately by means of the transfer unit (13).

4. An apparatus according to one of claims 1 to 3, characterized in that disposed upstream of the compartmented wheel (12) is a vertical stepwise driven mandrel wheel (5) having radially disposed shaping mandrels (5a) of rectangular cross-section on to which the folding box containers (4), still open at both ends and forming tube portions (2), can be slipped and at whose periphery fixed folding and closing tools (6-11) and possibly applicator tools for the application of a pouring means and/or closure are disposed, the transfer unit (13) disposed upstream of the compartmented wheel (12) having a pusher element by which the folding box container (4), closed at one end, can be pushed via a plate (12c) disposed alongside a compartment of the compartmented wheel (12) or between two adjacent compartments of two compartmented wheels (12a, 12b) can be pushed into the compartments in alignment therewith.

5. An apparatus according to one of claims 1 to 4, characterized in that the compartmented wheel (12) and/or the mandrel wheel (5) is or are mounted overhung.

6. An apparatus according to one of claims 1 to 5, characterized in that a slipping-on unit (3) for the tube portions (2) is disposed in the zone of the lower vertex of the mandrel wheel (5).
