Definitions

• the invention relates to a device for filling cans with a tough plastic filling.
• the invention has for its object to provide a device of the type mentioned, in which a special knife can be dispensed with.
• this object is achieved by a filling container which receives the filling material and is covered on one side with a sealing plate, a number of filling cylinders which are guided past the filling container to hold the filling material and are provided with a sealing flange, the filling cylinders being guided past the sealing plate rest flat on it, so that the filling material transferred from the filling container to the filling cylinder passing by it is sheared off between the sealing plate and the respective sealing flange.
• a preferred embodiment is characterized in that the recess is designed as an elongated hole with a length corresponding to a multiple of the diameter of the filling cylinder.
• the sealing plate is designed to be pressed against the sealing flanges of the filling cylinders.
• a preferred embodiment is characterized in that the filling cylinders are guided past the filling container on a circular path and the sealing flanges are essentially trapezoidal and are arranged so as to abut one another on their legs.
• 1 is a sectional view of the device in side view
• FIG. 2 shows a top view of the device shown in FIG. 1, FIG.
• FIG. 3 shows a representation corresponding to FIG. 1 when the cylinder has moved on
• FIG. 4 shows a representation corresponding to FIG. 2 in the position of the cylinder according to FIG. 3,
• Figures 1, 3 and 5 show that the device consists of a filling container 10 and a plurality of filling cylinders 16.
• the filling container 10 is closed at the top by a sealing plate 14, which is provided with a recess 12.
• a sealing plate 14 which is provided with a recess 12.
• the filling material which is introduced under pressure into the filling container 10 by means (not shown), is introduced upwards into the filling cylinder 16, which is on a circular path (see FIGS. 2 and 4) on the Recess 12 are passed.
• the recess 12 is in the form of a curved elongated hole, the diameter of which corresponds to the inside diameter of the cylinder, but can also be smaller than this.
• the filling cylinders 16 are each provided with sealing flanges 18, the sealing flanges 18 resting on the sealing plate 14.
• Fig. 5 illustrates that the elongated hole has an extent in which at least three cylinders 16 are filled simultaneously, with pistons 20 guided in the cylinders 16 being gradually moved upwards in accordance with the filling progress.
• FIGS. 6, 7 and 8 illustrate the passage of the cylinders 16 past the sealing plate 14.
• Figures 1, 3 and 5 further illustrate that the filling container 10 is designed so that the sealing plate 14 is vertically movable and thus can be pressed against the sealing flanges 18 of the filling cylinder.
• the sealing flanges 18 of the filling cylinders 16 slide on the sealing plate 14, the cylinders 16 in the area of the sealing plate 14 with the.
• Product to be filled rising from bottom to top.
• the cylinders 16 are completely filled when they leave the space above the recess 12.
• lumpy parts, some of which are still in the filling container 10, but some are already in the filling cylinder 16 between the one in FIG Arrow marked edge of the recess 12 and the edge of the sealing flange 18 of the respective fill cylinder 16 approaching this sheared off.
• This shearing action between the sealing plate 14 and sealing flanges 18 makes it possible to dispense with the provision of a special cutting device, in particular a knife.
• the proposed design of a filling device thus makes it possible, without the provision of a special cutting device, to reliably portion the filling material to be filled, for example, into cans, and lumpy parts without a special cutting device be casually sheared off between the sealing flanges and the sealing plate.
