Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a device for forming and pushing a filling.

(Prior art) In order to fill relatively thick and bulky solids such as Yuuri-zuke and Fukujin-zuke into small containers such as bottles, cans, or bags (hereinafter referred to as packaging containers), only natural fall is required. Since the specified amount does not fit in, fill it by pressing with a push rod.

(Problem that the invention aims to solve) By the way, there is a device that mechanically performs pushing with a pushing rod, but since one pushing is not enough, the product often breaks or is undersized, resulting in a decline in quality. will be invited. Therefore, the current situation is that we have no choice but to rely on manual labor, which significantly impedes productivity.

(Means for Solving the Problems) The present invention attempts to solve the above problems, and its features are that a molding chamber with a built-in plunger is disposed above the packaging container; A certain amount of the filling material is put into the molding chamber, and a plunger is operated to press-form the filling material into a columnar body that is slightly smaller than the shape of the packaging container, while a piston that moves up and down is placed above the pressing-forming position. The present invention is configured such that the columnar body can be filled into the packaging container by lowering the piston.

(Function) A certain amount of filler necessary to fill the packaging container is put into the molding chamber. Next, the cylinder is operated to compress the filling and form it into a columnar body that is slightly smaller than the shape of the packaging container, and then a piston is lowered from above to direct the columnar body into the packaging container at the lower position. Press to insert and fill.

(Example) FIG. 1 is a plan view of the device of the present invention, and FIG. 2 is a schematic explanatory diagram of the operating process.

This example shows a rotary table system, in which the filling is formed and pushed into the container by intermittent rotation of the rotary table 1, and in this example, the filling operation is performed by intermittent rotation in 8 steps.

Specifically, 2, 2', 2''... are molding chambers arranged at equal intervals around the periphery of the table 1, and in the illustrated example, each chamber has 2 molding chambers for the following two packaging containers. It has a configuration in which chambers 2a and 2b are arranged side by side.Each molding chamber 2a and 2b has a built-in plunger 3a and 3b, respectively, and the filling material introduced into the molding chamber from the outside by the operation of a cylinder 4 is inserted into the molding chamber. By compressing it to one end of each chamber, it is formed into a columnar body 15 that roughly matches the shape of the container.

On the other hand, the packaging container 6 is held at a position below each molding chamber 2 by a support means 8 attached to the back surface of the table 1 via a bracket 7, and for supplying, the packaging container 6 is connected to a rotary table 9 for supplying containers arranged adjacently. In other words, in the illustrated example, the packaging containers 6 on the conveying means 11 are received simultaneously through two notches 10a and 10b bored at the periphery of the rotary table 9, and the packaging containers 6 are received on the supporting means 8 by the intermittent rotation of the rotary table 9. It will be sent in and held. (Packaging container supply process A) B is a packaging container detection process in which the rotary table 1
A detector 5 such as a phototube or a limit switch is provided at the 1/8 rotation position of the notch 10.
If the packaging container 6 is not held at locations a and 10b, rotation of the rotary table 9 is stopped.

C is a filler charging step in which molding chambers 2a and 2b are
A filling material 13 is charged into the container via a charging hopper 12. 14 is an input guide.

D is a filler charging step in which the molding chamber 2a,
The filling 13 introduced into the molding chamber 2b is transferred to the molding chamber 2 through the plungers 3a and 3b by the operation of the cylinder 4.
a, 2b to form the filling 13 into a columnar body 15 slightly smaller than the shape of the packaging container 6.
E and F are steps for pushing the filling 13 into the packaging container 6 in which the piston 16 is lowered by the operation of another cylinder (not shown) from above, and the columnar body 15 is disposed at a lower position. Let it fill up.

G is a discharge step in which the filled packaging container 6 is removed from the support means 8 and transferred to the discharge conveyor 17.
In this case, reference numeral 18 is a discharge means using a parallel link mechanism.

(Effects of the invention) The invention is constructed as described above,
That is, in order to make it easier to put the filler 13 into the packaging container 6, it is formed in advance into a columnar body 15 with a size slightly smaller than the shape of the packaging container 6 in the molding chamber 2. This makes it possible to smoothly charge the filling material into the molding chamber 6, contributing to improved productivity.At this time, the amount of filling material is determined by pressing a certain amount stored in the molding chamber 6 with a piston. There are no shortages, and there is no problem of quality deterioration.
