  • Patent number: 11413821
    Abstract: A powder refill system for a CBAM process that makes changing a powder container simple and maintains the smallest possible distribution change during the print process. The system automates a constantly low trough powder level during a print and reduces the number of times the powder is recirculated. The system uses a sensor to sense the amount of powder in a tray and a compressed air powder application system to force powder into the system. Powder enters the system from a powder bottle mounted upside-down on a plate with an orifice and mixing chamber and a stainless-steel “aeration stone” This is a fitting with porous walls, where porosity is finer than most of particulate matter of the powder being used. Air can enter through the fitting, broken down into microscopic streams, but powder cannot enter back into the air supplying line. The powder aerosol is then used in the printing/flooding process. A mounting plate allows easy replacement of the powder bottle.

  • Patent number: 10853701
    Abstract: A method for preventing a malfunction of a filling device when a container is filled by a user with a beverage. The method includes providing a filling device comprising a control unit which controls the filling device, a camera which takes an image of a container currently being used with the filling device and which outputs the image to a classifier which then uses a trained learning algorithm to analyze the output of the image of the container provided by the camera. The trained learning algorithm of the classifier analyzes which container is currently being used based on characteristics of the container so as to classify the container into a predefined class. The predefined class is then employed by the control unit to prevent the malfunction of the filling device.

The plurality of food particles are transported upon a discharge conveyor having a first rate of speed, the plurality of particles arranged uniformly from passing beneath a product leveling device. When the plurality of particles reach the end of the discharge conveyor, the particles fall from the end of the conveyor under the operation of gravity and are deposited in a shuttle while the shuttle travels at a second rate of speed from a position at least partially below the conveyor to collect the falling particles in cells or receiving receptacles. The relationship between the first rate of speed of the conveyor and the second rate of speed of the shuttle define a metered amount of particles collected in each of the receiving receptacles.

  • Patent number: 7963302
    Abstract: An inspection machine for inspecting the volume of liquid contained by a bottle filed to its defined fill height. A head is lowered and has a sealing plate which seals the open finish of a bottle. A fill tube assembly is part of the head and continues to be lowered until a level sensor is located to sense liquid at a pre-fill level. High and low pressure water lines which are a part of the fill tube assembly are operated to fill the bottle to the pre-fill level. The sealing plate is released and then the process is repeated lowering the sensor to the post-fill level and operating only the low-pressure line to fill the bottle to the post-fill level. The total liquid filling the bottle is then computed.

  • Patent number: 6814108
    Abstract: Receptacles are precisely filled with particulate material by feeding the material from a supply source across a deflectable, curved weigh pan and discharging a continuous flow of material from the weigh pan along a pathway. Receptacles, which may be the final containers or intermediate receptacles, are continually fed by a conveyor into the pathway so that material flows into each receptacle opening. The amount of material flowing along the pathway is measured by deflection of the pan, and the speed of the receptacle conveyor is quickly adjusted responsive to the deflection of the pan, thereby controlling the time that a given receptacle is within the pathway and the precise amount of material placed into the receptacle. The amount of material flowing to the pan from the supply source can also be controlled responsive to the pan deflection.

  • Patent number: 6722403
    Abstract: A bifurcated bracket carries two powder dispensing assemblies. Each assembly includes a powder reservoir and a rotatable screw received within a compliant silicone sleeve. The outer diameter of the screw is slightly larger than the inner diameter of the sleeve such that the screw blade maintains direct contact with the sleeve wall as the screw is rotated. The bracket is sequentially moved to align each assembly with containers in two arrays. Each array of containers is situated in a tray. The trays are manually positioned on independent scales which generate signals that are a function of the sensed weight of each array. To fill each container, the screw in the aligned assembly is rotated at a high rate for an initial period and then at a slower rate. The scales are operational only during the slower rate period. Assembly movement and screw rotation are computer controlled.
