Benefits of technology

[0009] In accordance with the present invention, a method and corresponding apparatus provide a non-invasive linear peristaltic pump with increased accuracy. Peristaltic pumps currently on the market are not linear, as the product tube is wrapped around a rotating carousel and restrained in a circular housing. As the product tube is stretched around the circular carousel, the inner passage of the product tube is no longer circular. As such, when the product tube in the peristaltic pumps is compressed, the output is non-linear. Therein, peristaltic pumps currently on the market are not useful in application where high accuracies are desired.

Embodiment Construction

[0031] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. It is further to be understood that the figures are not necessarily to scale, and some features may be exaggerated to show details of particular components or steps.

[0032] The preferred embodiment is a method and apparatus for dispensing products using a peristaltic pump that includes a straight or linear segment to provide a more consistent dispense. The linear peristaltic pump includes provisions for metering fluid products or semi-fluid products. The linear peristaltic pump is non-invasive to the product. As such, it may be utilized on wide ranges of food products and food product dynamics. Low viscosity products may flow to the pump freely; however, semi-viscous and high viscosity products may be dispensed with the assistance of an evacuation device to...

Abstract

A method and accompanying apparatus dispenses product with a non-invasive linear peristaltic pump. The linear peristaltic pump includes a traction plate having a linear portion, a depressor and a driver. The depressor compresses the product tube between the linear portion and the depressor, such that an inner passage of the product tube is substantially sealed. The driver moves the depressor along the linear portion of the traction plate, such that the product tube located between the depressor and the linear portion is compressed along the linear portion. Product in an inner passage of the product tube is thereby moved or dispensed. Another embodiment may include depressors attached to belts, wherein successive depressors may be driven along the linear portion to dispense or move the product. A method for using a linear peristaltic pump and the use of a controller to dispense product is also provided.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method and apparatus for pumping a product and, more particularly, but not by way of limitation, to pumping a product with a linear peristaltic pump. [0003] 2. Description of the Related Art [0004] In an attempt to remain competitive in the industry of packaged foods and food type products, retailers are continually forced to evaluate their packaged foods, as well as their product dispensers. In attempts to maximize profits, retailers are moving to less expensive packaging on the food products they use. Many attempts have been made to simplify package loading and unloading in a dispenser; however, the added burden associated with complex packaging is indirectly passed on to the product. [0005] The least expensive form of packaging currently on the market is a soft package with a fitting permanently affixed to one side. The fitting provides the user with a means to connect an evacua...
