Abstract

The present disclosure relates to a device for guiding and pivoting bodies via sliding the bodies through the device. The device is produced using a generative manufacturing method. A system includes at least two of the devices arranged in parallel, a conveyor device, and a control device. The control device controls the conveyor device responsive to receiving a control command and feeds bodies selectively to one of the devices. A treatment line for polyethylene terephthalate (PET) containers includes a process path, a preform storage unit, a preform oven of a stretch blow-molding machine, and the device arranged between the preform storage unit and the preform oven. A treatment line for PET containers includes a process path, a container closure storage unit, a closing unit for closing the PET containers, and the device arranged between the container closure storage unit and the closing unit.

First claim

What is claimed is:

1. A device for guiding and pivoting bodies, wherein the device was produced using a generative manufacturing method:
wherein the device comprises at least one wear strip, the at least one wear strip being fixed in a shaped groove of the device in a form fit manner;
wherein the guiding and pivoting of the bodies comprises sliding the bodies on the at least one wear strip of the device; and
wherein the bodies comprise at least one of cans, preforms, bottle closures, cardboard containers, or flasks.

2. The device of claim 1 , wherein the device comprises at least one of a plastic, a metal, or a mixture of at least one plastic and at least one metal, and wherein the device is composed of a plurality of modules joined together by screwing, gluing, or welding.

3. The device of claim 1 , wherein the device is configured to contact the bodies in a form fit manner in at least three surface areas for the guiding and the pivoting.

4. The device of claim 1 , wherein the device is configured such that, cooperating with the bodies, the device contacts the bodies substantially with an entire interior surface of the device to achieve the guiding and the pivoting.

5. The device of claim 4 , wherein the device is configured such that, cooperating with the bodies, it substantially defines a closed surface relative to the bodies for the guiding and the pivoting, wherein the closed surface comprises a wall with lateral sides.

6. The device of claim 4 , wherein the device has openings of a predetermined size on an underside of the device.

7. The device of claim 6 , wherein a liquid medium is to be at least one of fed into the device via the openings or discharged from the device via the openings.

8. The device of claim 4 , wherein a bottom surface of the device is defined by at least one conveyor belt configured to at least one of feed or discharge the bodies.

9. The device of claim 1 , wherein the device comprises fastenings to attach to other conveyor units, the fastenings are attached to the device via the generative manufacturing method.

10. The device of claim 1 , wherein at least one of:
the at least one wear strip comprises ultra-high-molecular-weight polyethylene (UHMW-PE) with glass components;
an outer surface of the device is, sectionwise, provided with openings for inserting the at least one wear strip; or
the device comprises at least one fixing configured to prevent the at least one wear strip from slipping out in a conveying direction.

11. The device of claim 1 , further comprising:
a blow-off unit configured to allow product residues to be removed from an outer surface of the bodies, wherein at least one of a) ducts for a blow-off medium are separately formed and follow a course of the device or b) ducts for the blow-off medium are integrated in body-carrying parts of the device.

12. The device of claim 1 , further comprising channels for feeding a friction-reducing medium, wherein ducts for the friction-reducing medium are at least one of a) configured separately and follow a course of the device or b) integrated in parts of the device.

13. The device of claim 1 , wherein the device comprises channels for supplying a gas, wherein the device is equipped with openings for directing a flow of the gas.

14. The device of claim 1 , wherein the device comprises at least one nozzle arranged below a path of movement of the bodies and configured to clean the bodies, wherein at least one of a) the at least one nozzle is adapted to have a cleaning medium applied thereto or b) the at least one nozzle is arranged in an area where, through a cooperation between the device and the bodies, openings of the bodies face downwards.

15. The device of claim 1 , wherein:
electronics are integrated in the device;
the electronics comprise one or more of non-contact sensors, optical detection devices, or radio-frequency identification (RF ID) tags; and
the electronics are integrated via the generative manufacturing method or the electronics are configured as modular interchangeable elements.

16. The device of claim 1 further comprising resilient portions for tolerance compensation, wherein the resilient portions are at least one of a) made of a material other than the material of the device orb) are pneumatic, mechanical, or hydraulic.

17. The device of claim 1 , wherein the device is adapted to have a cleaning agent applied thereto, wherein the cleaning agent is to be applied to the device via a plurality of channels and openings in the device to provide a predetermined wetting of the device, and wherein the cleaning agent comprises at least one of a disinfecting cleaning agent or water under high pressure.

18. The device of claim 1 , wherein the device is arranged on a basic body, wherein at least one of:
the basic body comprises recycled plastic; or
a weight ratio of the device to the basic body is greater than 10%.

19. The device of claim 1 , wherein the device is composed of a plurality of modules joined together by the generative manufacturing method.

20. A method comprising:
identifying a digital model;
receiving material that is shapeless or neutrally shaped; and
producing, via generative manufacturing based on the digital model, a device by applying one or more chemical or physical processes to the material, wherein the device comprises at least one wear strip, the at least one wear strip being fixed in a shaped groove of the device in a form fit manner, wherein the device is configured to guide and pivot bodies, wherein guiding and pivoting of the bodies comprises sliding the bodies on the at least one wear strip of the device, and wherein the bodies comprise at least one of cans, preforms, bottle closures, cardboard containers, or flasks.
