Slicing Apparatus

Patent No. US12246467 (titled "Slicing Apparatus") was filed by Weber Food Technology Se & Co Kg on Apr 21, 2023.

What is this patent about?

’467 is related to the field of food processing, specifically high-speed slicing apparatuses used to cut food products like meat and cheese into slices. These slicers are often part of automated production lines where consistent product supply is crucial for maintaining efficiency. The patent addresses the problem of manually loading food products onto the slicer's feeding unit, which can be labor-intensive and lead to production bottlenecks if the operator fails to replenish the product supply in time.

The underlying idea behind ’467 is to automate the loading process of a food slicer by using a loading apparatus with a magazine unit . This unit employs a circulating conveyor system to lift food products from a convenient loading height to the slicer's feeding unit. An entraining device then automatically transfers the lifted product to the feeding unit, ensuring a continuous and ergonomic supply of food products to the slicer.

The claims of ’467 focus on a slicing apparatus that includes a feeding unit with a trimming cutter to remove unwanted portions of the food product *before* slicing. A selection gap is positioned after the cutter to remove the trimmings. Crucially, a scanning device analyzes the product *through* this selection gap as it enters the cutting region.

In practice, the loading apparatus lifts a series of food products to a transfer height, where an entraining device pushes them onto the slicer's feeding unit. Before reaching the blade, a trimming cutter removes any undesired parts, such as excess fat. These trimmings fall through the selection gap, allowing the scanning device to analyze the product's dimensions and characteristics *after* trimming but *before* slicing. This information can then be used to optimize the slicing process.

This design differentiates itself from prior solutions by integrating trimming, waste removal, and scanning into a streamlined process. By scanning the product *after* trimming, the slicing apparatus can make more informed decisions about slice thickness and portion size, leading to reduced waste and improved product consistency. The automated loading and transfer system further enhances efficiency by minimizing manual labor and ensuring a continuous product flow.

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2020s when ’467 was filed, food product slicing systems commonly relied on automated feeding mechanisms to increase throughput, at a time when continuous operation was typically implemented using manual loading of product onto the feeding unit, when hardware or software constraints made fully automated loading non-trivial.

Novelty and Inventive Step

The examiner approved the claims because the prior art did not disclose a scanning device that scans products fed over a selection gap into the cutting region, where the scanning device is arranged to scan the products through the selection gap, in combination with other claim limitations.

Claims

This patent has 5 claims, with claim 1 being the only independent claim. Independent claim 1 is directed to a slicing apparatus that uses a trimming cutter and a scanning device. The dependent claims generally elaborate on specific features and arrangements of the trimming cutter and feeding unit described in the independent claim.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Scanning device
(Claim 1)
“Further, the slicing apparatus may comprise a scanning device to infer information concerning the products that are fed into the cutting region. In particular, the scanning device may be arranged at a selection gap formed by the feeding unit. For example, the scanning device may comprise a camera and/or one or several illumination sources, in particular LED, to illuminate the product through the selection gap and determine the product contour, the products size and/or the product weight.”A device that analyzes the food products as they pass over the selection gap, providing data about the product.
Selection gap
(Claim 1)
“According to another aspect, a selection gap for sorting out a part of the product may be formed in the feeding unit. In particular, the feeding unit may comprise a moving device with a first conveyor belt and a second conveyor belt and the belt transition may be used as a selection gap for sorting out product parts that are not usable and need to be removed. For example, the selection gap may be arranged subsequently to a trimming device that cuts of a part of a product that is fed into the cutting region.”A physical gap in the feeding unit that allows the portion of the food product removed by the trimming cutter to fall away from the main product stream.
Trimming cutter
(Claim 1)
“The feeding unit may comprise a trimming cutter to cut off a part of the product during the feeding into the cutting region, in particular before the product is cut into slices in the cutting region. In particular, the trimming cutter may be configured to and/or arranged to cut the products along the feeding direction. For example, the trimming cutter may comprise a blade, in particular a circular blade, rotating in or against the feeding direction to cut off a part of the product.”A component of the feeding unit that removes a portion of the food product as it is being fed towards the cutting region. It cuts along the feeding direction.
