A buffer conveyor (12) for conveying conformable work products (66) includes a collapsible conveyor belt (13) having an infeed section (14), a collapsible intermediate section (16) and an outfeed section (18). The infeed section (14) may be driven at a non-continuous speed, and the outfeed section may also be driven at a uniform, or non-continuous, speed, but the average speed of both the infeed and outfeed sections is the same. The intermediate section of the conveyor is driven at a non-uniform speed that is slower than, but proportional to, the speed of the infeed section.

The automatic fillet-trimming machine comprises a first conveyor belt that is capable of registering the weight of the individual fillets, one or more computer-controlled cameras or other imaging means that identifies and localizes the undesired portions of a fish fillet to be removed, a height-measuring apparatus the registers the thickness of the fillets, a second conveyor belt that comprises suction means for securely holding the fillets, and which transports the fillets to a plurality of computer-controlled cutting devices, the movement of which is directed according to coordinates received from the imaging means, and means for weighing and removing waste products.

The present invention relates to a method for automatically removing bones and trimming a product such as fish fillets, where the fillets are in an under cooled state. The under cooling makes the fillets sufficiently stiff to remove pin pones and portion a fillet before or after skinning the fillet in a relative still position providing better cutting than conventional methods. This provides more efficiency than prior art methods as well as increasing the value of the product due to less gaping and dehydration of the product. The method of the present invention further provides possibilities for grading of products processed with the three dimensional scanning and digital imaging of the products.

A slicing machine for slicing meat strands that have a cross section that varies over a longitudinal extension in large numbers and as quickly as possible into weight precise slices. In one embodiment, two meat strands are received adjacent to each other in a respective form tube and pushed against a respective separately adjustable stop plate independently from each other by a controlled longitudinal press plunger and compressed in the longitudinal direction. In addition, a cross section of the form tubes may be reduced in a first transversal direction jointly and in a second transversal direction independently from each other and thus the respective meat strand is transversally compressed to a constant cross section prior to slicing.

Apparatus for high-volume, high speed ultrasonic cutting or slitting comprising a blade having first and second cutting edges suspended from a reciprocating head, cantilevered over a conveyor supporting and advancing the food product, with the blade including first and second cutting edges on respective opposite sides thereof to cut the food product transversely. The head is preferably controlled for automated operation by an electronic controller to reciprocate transversely at a selected speed and a selected frequency within predetermined ranges over food product advancing on the conveyor. The blade preferably oscillates ultrasonically, and preferably at a frequency of approximately 20,000 Hz. The first and second cutting edges are preferably downwardly convergent, defining an included angle greater than 60 degrees and less than 90 degrees. In one particular embodiment, the internal angle is 70 degrees. In another embodiment, the angle is about 60 degrees. The blade may have a linear translating velocity of 25 to 35 inches per second, and more specifically may have a transverse velocity of approximately thirty inches per second. The apparatus may be used in high-speed, high-volume commercial food production operations for automated cutting of cheese products and other food products from large chunks, slabs and the like into smaller portions, and may also be used in other applications.

An apparatus and method for displaying the weight or cost of an uncut selected segment of an item involves passing a position indicating member over the item lying on a support surface. The position indicating member carries one or more sensors which generate signals corresponding to cross sectional contours of the item as the member is traversed along the item from a reference position to a selected other position over this item, defining the selected segment of the item. A motion detector arrangement preferably comprised of one or more microelectromechanical accelerometer devices generates signals corresponding to motion of the position indicator support member as it is moved along the item. These signals are processed in a signal processor to determine the volume of the segment of the item lying between selected successive positions of the indication member. The segment volumes are converted into numeric weight or price values.
