Abstract: An empty bag supplying apparatus used in a continuous conveying type bag-filling packaging machine in which the empty bag supplying apparatus receives empty bags and transfers these empty bags to gripper pairs of the bag-filling packaging machine that are moved continuously at a constant speed. The empty bag supplying apparatus includes downward-facing bag holding members and a reciprocating movement mechanism. The bag holding members hold the upper portions of bags. The reciprocating movement mechanism causes the bag holding members to reciprocate along an arc-shaped path and keeps the empty bags held by the holding members to be parallel to the direction of movement of the gripper pairs during the reciprocating motion. In a bag transfer region established in the arc-shaped path path, the speed of the bag holding members holding the empty bags is equal to the moving speed of the gripper pairs.

Abstract: A batching of currently supplied articles with non-uniform weights into portions of a uniform target weight is effected by passing the articles through a weighing station (6, 8) to a distribution system (12), in which the articles (4) are selectively allocated to a plurality of receiver bins (14). It is known to improve the capacity of such a system by way of probability calculations based on the normal distribution of the articles in the supply flow, but according to the invention it is still better to base such calculations on a regularly updated recorded histogram (28) of the weight distribution of a relatively high number of newly weighed articles. Thereby the target calculations will rely on factual rather than just expected conditions, and a very important result is that it is possible to effect relevant batching even when the article weights in the supply flow are not normally distributed.

Abstract: Disclosed is a fluid dispensing system for precisely controlling the mixing of a first fluid (i.e., a diluent such as water) with a second fluid (i.e., a concentrate) at a mixing point within the fluid dispensing system. A valve is positioned in the dispensing system along the line of supply of the second fluid upstream of the mixing point, such valve being simultaneously actuated through application of positive and/or negative pressure to allow the second fluid to flow through the valve. The application of positive and/or negative pressure is generated from the first fluid to be dispensed by the system and mixed with the second, such that the termination of flow of the first fluid immediately terminates flow of the second fluid to ensure proper mixing of the two fluids in the final solution, thus preventing inadvertent leakage of the second fluid or collection of the second fluid within the flow system which may become subject to spoilage or contamination.
