Abstract

A packaging machine is for packaging articles with a film. The packaging machine has: a housing; an infeed belt configured to feed an article to be packaged in a transport direction to a film packaging device in the packaging machine; and a weighing device configured to determine a weight of the article. The weighing device has a weighing belt configured to convey the article from the weighing device to the infeed belt in the transport direction. The weighing device is rigidly connected to the infeed belt. The weighing device and the infeed belt together form an infeed module that is removeable from the housing. The removable infeed module has a shared fastener for being releasably fastened to the housing.

First claim

The invention claimed is:

1. A packaging machine for packaging articles with a film, the packaging machine comprising:
a housing;
a lifting platform arranged within the housing, the lifting platform comprising columns configured for transporting an article against the film for a folding operation;
an infeed belt configured to feed the article to be packaged in a transport direction to a film packaging device in the packaging machine; and
a weighing device configured to determine a weight of the article,
wherein the weighing device comprises a weighing belt configured to convey the article from the weighing device to the infeed belt in the transport direction,
wherein the weighing device is rigidly connected to the infeed belt,
wherein the weighing device and the infeed belt together form an infeed module that is removeable as unified component from the housing,
wherein the removable infeed module has a shared fastener for being releasably fastened to the housing, the shared fastener being arranged such that the weighing device and the infeed belt are removeable from and installable into a fitted state in the packaging machine as the infeed module in a unified manner,
wherein the weighing device and the infeed belt are rigidly connected by a shared support for forming the infeed module, and
wherein the infeed belt comprises conveyor belts configured to transport the article. the conveyor belts being arranged next to one another, configured to engage in the lifting platform of the packaging machine in a condition where the infeed module is in the fitted state in the packaging machine, and configured to be arranged between the columns of the lifting platform in the fitted state.

2. The packaging machine according to claim 1 , wherein the fastener is configured to fasten the infeed module to the housing so as to be releasable without the use of tools.

3. The packaging machine according to claim 1 , wherein the infeed module has first slide surfaces configured to bear on a bearing surface of the housing in a condition where the infeed module is pushed into the housing.

4. The packaging machine according to claim 3 , wherein slide rails configured to abut corresponding second slide surfaces of the infeed module are on the bearing surface of the housing.

5. The packaging machine according to claim 1 , wherein the infeed module comprises guide bolts, which are configured to engage in corresponding guide-bolt receptacles in the housing for guiding the infeed module in a condition where the infeed module is being pushed into the housing.

6. The packaging machine according to claim 1 , wherein the infeed module has a plug that is configured to be inserted into a corresponding plug socket in the housing in order to fasten the infeed module to the housing.

7. The packaging machine according to claim 6 , wherein the plug has a guide pin that is configured to be pushed into a corresponding guide pin receptacle in the housing.

8. The packaging machine according to claim 1 , wherein the packaging machine comprises a removable cover configured to cover the infeed module, the cover having eyes configured to be releasably mounted on eye retainers of the housing of the packaging machine.

9. The packaging machine according to claim 8 , wherein a sensor is provided on the housing, the sensor being configured to detect whether the cover is fastened to the housing of the packaging machine.

10. The packaging machine according to claim 1 , wherein the packaging machine comprises guide elements on the housing of the packaging machine that are configured to guide the infeed module during removal and installation such that the infeed module is automatically positioned into the fitted state where the conveyor belts engage in the lifting platform, the guide elements projecting from the housing of the packaging machine.

11. The packaging machine according to claim 10 , wherein the packaging machine comprises latching bolts of the infeed module that are configured to engage in corresponding latching-bolt receptacles in the guide elements on the housing of the packaging machine.

12. The packaging machine according to claim 11 , wherein the latching bolts have a spring mechanism for unlocking or locking the infeed module on the housing of the packaging machine.

13. The packaging machine according to claim 1 , wherein a protective bracket is provided for setting down the infeed module such that the infeed module is configured to be set down when it has been taken out of the packaging machine.

14. The packaging machine according to claim 1 , wherein, to transport the article from the weighing belt to the infeed belt, a sliding plate is arranged between the infeed belt and the weighing belt.

15. The packaging machine according to claim 1 , wherein the packaging machine comprises a protective plate of the weighing belt, the protective plate being releasably fastened to the weighing belt.
