Description

  The present invention relates to suction of a fluid used when a package (container) being transported is filled with a fluid such as gas, liquid, processed food, paint, or various materials from one or a plurality of sources via a transport means. -It relates to a delivery plunger type pump.

  Japanese Patent No. 3245857 is described as an example of the prior art. This publication describes a soup delivery plunge pump as an example of processed food.

  In this pump, when the soup containing ingredients is put into the popper and the inner valve rotates by a predetermined amount, the upper opening formed in the outer valve communicates with one suction / delivery opening formed in the inner valve. A predetermined amount of utensils and soup flow into the inner valve, and then, after the inner valve has rotated a predetermined amount (180 degrees), a plunger that fits into the inner valve moves forward, soup formed below the tip of the outer cylinder The extraction opening and the one suction / delivery opening of the inner valve communicate with each other and are used to take out a desired soup containing the ingredients in one cup.

  Therefore, in the above publication, “a cylindrical valve body having a box-shaped valve body and a cylinder for storing fluid in the valve body and slidingly rotating on the inner peripheral surface of the valve body by the driving force of the driving source. A fluid delivery plunger type pump having an inner valve and a plunger that has a piston built in the cylinder of the inner valve and reciprocates by a driving force of a driving source is described. This corresponds to the prerequisite of the present invention.

  A conventional example is effective for dispensing soups in one cup, but only one suction hole and one discharge hole are formed in the valve body. There was a problem that sending takes too much time.

  That is, after the plunger has moved forward and the soup containing the desired ingredients has been taken out into one cup from the opening for taking out the outer cylinder, the plunger and the inner valve must be reversed by the driving force of the driving source. For example, one opening of the inner valve does not communicate with one suction hole of the valve body.

Therefore, starting from the basic configuration (or principle) described above, a plurality of packages (in the form of processed foods, paints, various materials, etc.) that are being conveyed from one or more sources via a conveying means ( There has been a demand for the emergence of a fluid suction / delivery plunger type pump that can be used when a container is continuously filled in a predetermined order. The basic configuration of the plunger type pump is described in Patent Documents 2 and 3.

  Accordingly, the fluid 92 flows into the second storage chamber 87 from the second suction hole 42 and the second opening 64 in association with the advance of the plunger 7, and at the same time, the first opening 61 and the first discharge hole 33 through the first The fluid in the storage chamber 86 is delivered.

  The first suction hole 32, the second suction hole 42, the first discharge hole 33, the second discharge hole 43 on the valve body 1 side, the first opening 61 on the inner valve side that can selectively communicate with these holes, the first The two openings 64 are formed in the axial direction (including the oblique direction) of the plunger 7 but may be formed in the radial direction of the plunger 7 (direction perpendicular to the plunger) depending on the design. The communication state of the opening (61.64) of the inner valve 6 with respect to the suction hole and the discharge hole on the valve body 1 side can be arbitrarily designed.

  The present invention can be used to suck and discharge fluid regardless of gas or liquid. In the case of liquids, it is suitable for pumping fluids or semi-fluids such as tomato chips, mayonnaise, ice cream, soups with ingredients, paints, cosmetic creams, paste-like toothpaste, etc. from the source to the filling object (container) To do.
