DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention is based on a package delivery device in filling and closing machines. Besides the well-ordered output of just finished packages, this kind of package delivery device is also used to hold down the freshly glued top closure of sacks or collapsible cardboard packages until the applied glue in the top closure has hardened and bonded so that the top closure is secured. In order to adapt the clearance between the conveyor belt and the loaded top belt to the format or the filling level of the packages, in known package delivery devices, the conveyor belt can be vertically adjusted since the closing device of packaging machines works at a constant level. Accordingly, the forwarding conveying devices for the packages must be adapted to the changing vertical position of the conveyor belt of the package delivery device.
ADVANTAGES OF THE INVENTION
The package delivery device according to the invention, with the has the advantage that when being adjusted to changing package heights, despite having a simple and clear structure, it uses its arrival end and its delivery end to easily adapt to the constant arrival and delivery height of the packaging machine and a subsequent conveying device for passing on the packages. The invention has an embodiment with the features set forth hereinafter has particular advantages by means of which, in an adjustment, the adaptation of the arrival end and the delivery end is carried out jointly. The invention set forth herein, moreover, produces a particularly simple construction of the device.
BRIEF DESCRIPTION OF THE DRAWINGS
An exemplary embodiment of the invention is represented in the drawings and is described in detail below.
FIGS. 1 and 2 show longitudinal sections through the delivery device in a minimal and maximal setting.
DESCRIPTION OF THE EXEMPLARY EMBODIMENT
The delivery device constitutes the end of a filling and closing machine for sacks or collapsible cardboard boxes. It ends at a closing device which applies an adhesive or glue for sealing the top closure of the packs or packages 1, and is used to hold the top closure during the bonding time of the adhesive or glue and for transferring the packages 1 to a conveying device 11, for example a multi-pack machine. In the filling and closing machine, on a bottom rail 12, which can be adjusted vertically for regulating fill height and changing format, the packages 1 are transported continuously by carriers 13 of a conveying device and are finally introduced into the delivery device.
The delivery device has a rolling rack 20 that has two similar parallel portal supports, each with a pair of vertical feet which are connected to each other with two longitudinal pairs of bars 23, 24 and two lateral pairs of bars 27, 28. An endless conveyor belt 31 and an endless top belt 41 spaced above it are disposed in the rolling rack 20. The conveyor belt 31 runs via two deflecting rolls 32, 33 which are supported in rotary fashion in the end sections of a longitudinally extended carrying frame 34. The feed side 35 of the conveyor belt 31 oriented toward the top belt 41 is supported by a number of parallel support rolls 36, which are supported in the carrying frame 34 in rotary fashion. On its delivery end, the carrying frame 34 is supported in two catches 37, which protrude at the one portal support 21, so that it can pivot around the axis of the delivery end deflection roll 33 and is supported in hinged fashion on the arrival end by two stilts 38 that are part of an adjusting device.
In a manner similar to the conveyor belt 31, the top belt 41 that covers it runs via two deflection rolls 42, 43, which are supported in rotary fashion in a second carrying frame 44. The feed side 45 of the top belt 41 oriented toward the conveyor belt 31 is loaded by a number of parallel weighted rolls 46, which are supported in the carrying frame 44 in rotary fashion with a lot of play. On its arrival end, this carrying frame 44 is supported in two catches 47, which protrude at the other portal support 22, so that it can piv
