摘要:
The invention is a weighing and feeding system for accurate weighing of small quantities of material in pelletized form and feeding the weighed material to processing machines. In particular the invention, is suitable for the preparation of weighed quantities of masterbatch to be added with resin directly into injection molding or extrusion machines for the manufacture of plastic products.
摘要:
A weighing arrangement comprising an infeed for product material to be weighed and at least one dosing mechanism for controlled conveying of product material portions from said infeed to a weighing system. The dosing mechanism comprises a motor-driven transport screw formed as a helically shaped rod positioned in a trough for conveying the product material from the infeed to the weighing system and a control unit for controlling the motor in order to deliver a desired portion of product material to the weighing system. This weighing arrangement makes it possible to provide a well-defined conveyance of product materials, which are not suited for vibrational conveyance.

The present invention relates to a method of conveying and selectively discharging food products by providing a feeding system. The feeding system (14) comprises an inlet end (20), an outlet end (22), a receptacle (24) below the outlet end, a determination unit at the outlet end (22) and a feeder (18) for conveying the food products from the inlet end to the outlet end. When no food product is present at the outlet or in the receptacle (24), the food products are conveyed at a first average velocity. When a food product is present at the outlet end (22) and no food product is present in the receptacle (24), the food products are conveyed at a second average velocity. The second average velocity is lower than the first average velocity. When the food product is leaving the outlet end or is received within the receptacle (24), the feeder (18) is stopped until the individual food product has left the receptacle.

Die Erfindung betrifft eine Dosiervorrichtung zum kontinuierlichen und kontrollierten Dosieren kleiner Mengen eines Pulvers, insbesondere eines pharmazeutischen Wirkstoffs oder eines Sprengstoffs. Die Erfindung umfasst eine Dosiervorrichtung mit einem Dosierrohr (40) und einem im Dosierrohr (40) angeordneten Dosiersieb (60) sowie eine stromaufwärts des Dosiersiebs (60) im Dosierrohr (40) angeordnete, drehantreibbare Verteilvorrichtung (50) zum großflächigen Verteilen eines dem Dosierrohr (40) zugeführten Pulvers über die Siebfläche (62) des Dosiersiebs (60).
摘要:
The invention concerns a device for sampling powdery products in dosed amounts, comprising a storing reservoir (1) of the powdery product in which is inserted a conduit (2) provided inside with means (3) for taking samples of the powdery product. Said means (3) take samples of the product from the reservoir (1) and conveys it from a loading orifice (4) of the conduit located inside the reservoir towards a delivery orifice (5) arranged in the conduit outside the reservoir. The delivery orifice (5) is associated with a sealing element (7) which can be controlled to be positioned and maintained either in a position entirely clearing said orifice, or in a position closing said orifice. In that latter position, there is still a ring-shaped space between the orifice (5) and the periphery of the sealing element (7), the width of the ring-shaped space being of the same dimension as the size of the grains constituting the powdery product. The entirely clearing position enables a maximum delivery rate of the powdery product. and the sealing position a very slight delivery resulting in high accuracy for measuring out.

The total weight of a plurality of resin products is set as a reference value, and a first upper-limit threshold and a first lower-limit threshold are respectively stored in a control circuit 38 on the upper limit side and the lower limit side with respect to the reference value. A second upper-limit threshold which is yet greater than the first upper-limit threshold and a second lower-limit threshold which is yet smaller than the first lower-limit threshold are stored in the control circuit 38. When the total weight of the resin products is greater than the first upper-limit threshold, a determination is made by the control circuit 38 as to whether or not the total weight of the resin products is yet greater than the second lower-limit threshold. Further, when the total weight of the resin products is less than the first upper-limit threshold, a determination is made by the control circuit 38 as to whether or not the total weight of the resin products is yet less than the second lower-limit threshold.
摘要:
An ice bagger (10) comprises an ice maker (11, 12), an ice bagging unit (13) which includes an automatic sanitation system (120) and a merchandiser (14). The ice maker delivers particulate ice into a hopper (15, 16) housed within the ice bagging unit. The ice bagging unit (13) includes a bag carrier which retrieves a bag carrier (39) from a bag supply (24) and opens the bag underneath a delivery chute (19) communicating with the hopper via an auger (18). A scale (65) supports the bag during its filling to measure the weight of the ice delivered into the bag from the hopper. A heating element (99) then activates to seal the bag closed. Once the bag has been closed, the scale pivots to deliver the sealed bag of ice into the merchandiser while the sealer arm raises to its original position. Additionally, the ice bagger further comprises a sanitizing system (120) which periodically activates to sanitize the hopper.
摘要:
Both a method and a container for the measuring and mixing together of a number of different materials are described. The container has been provided with weight recorders, so that the contents of the container can be weighed. For supply of the materials a number of dosing screws is provided. To compose a mixture with a predetermined composition a first dosing screw is operated until the weight recorders indicate that the required weight of the materials supplied by the first dosing screw has been entered into the container, after which the second dosing screw is operated until the weight recorders indicate that the second required weight of the materials supplied by the second screw has been entered into the container, taking into account the weight already present in the container, etc. Subsequently the constituents are mixed in the container and finally discharged by rotating the container.
