The object is to push out the encapsulated object b filled in the packaging bag a while vibrating and to destroy the air contained in the encapsulated object. [Structure] A machine frame to which a push rod that pushes the object filled in the packaging bag to the bottom of the bag and removes the contained air can be lowered,
A vibrating push rod device for a filled envelope, comprising a vibrator, wherein the push rod is moved up and down together with the vibrator to vibrate the push rod by the machine frame.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, an object filled in a packaging bag a hung by a plurality of pairs of support arms in the radial direction provided on the intermittently rotating packaging machine body is pressed against the bag bottom and compressed, and the compression air generated at that time is compressed by the packaging bag a. In the device that is excluded to the outside, the push rod vibrates to increase the compression efficiency.

[0002]

[Prior art]

 It has already been practiced to use a push rod that pushes an object to be packed in a packaging bag to the bottom of the bag to remove contained air. However, since the push rod simply pushes against the object to be encapsulated, the efficiency of eliminating the air contained in the lightweight filling material such as shaving bonito, which is easy to fly up, is not good. However, when the packaging machine is vibrated, the function of the packaging machine is adversely affected, and since the push rod is small, it is difficult to obtain a structure that compresses the envelope while vibrating. It takes much research and effort to devise a push rod device.

[0003]

[Problems to be solved by the device]

 The present invention not only moves the push rod up and down, but also attaches the push rod to a machine frame suitable for mounting a small vibrator, and fills the packaging bag a while vibrating the push bar through the machine frame. The present invention aims to develop a device suitable for pushing the encapsulated object b to eliminate the air contained in the encapsulated object.

[0004]

[Means for Solving the Problems]

 The vibrating push rod device of the filled envelope of the present invention meets the above-mentioned purpose, and is a machine frame in which a push rod that pushes the envelope filled in the packaging bag to the bottom of the bag and removes the contained air can be lowered. The present invention relates to a vibrating push rod device for a filled envelope, which is characterized in that a vibrator is mounted on the vibrator, and the push rod is moved up and down together with the vibrator to vibrate the push rod by a machine frame.

[0005]

[Action]

 According to the present invention, the machine frame 17 having the vibrator 20 and the push rod 21 mounted thereon is lowered by the second arm 16 attached to the elevating rod 12, and while the push rod 21 is vibrated, the package b filled in the packaging bag a is b. Is pressed against the bottom of the bag, and the air contained in the object to be encapsulated b 1 is driven out by the vibration of the push rod 21 and can be compressed.

 1 is a schematic plan view, FIG. 2 is a partially cutaway front view, FIG. 3 is a side view of a lower portion of FIG. 2, and FIG. 4 is a main part of the present invention. FIG. 5 is a side view of the machine frame, and FIG. 5 is a front view showing an example of pressing of the envelope with a push rod.

In the figure, 1 is a machine base, and 2 is a plurality of pairs of mounting arms which are provided from an intermittent rotation packaging machine mounted on a rotating shaft provided at the center of the machine base, with the corresponding intervals being freely adjustable. And project in the radiation direction at regular intervals. A packaging bag is supplied to each pair of mounting arms 2 by a bag supply station, and as shown in FIG. 1, the packaging bag filling station III, the first pressing station IV, the second pressing station V, etc. are intermittently stopped and rotated. The machine base 1 is provided with a sliding guide pipe 4 projecting to the lower surface between the first and second pressing stations, a guide rod 5 is attached to the lower surface in a hanging shape, and a large diameter portion of the rotary cam 6 is provided. The U-shaped portion 10 at one end of the guide rod 5 is fitted to the tip of the lever 7 which swings to the two positions of the solid line and the chain line in FIG. The horizontal bar 8 to which the elevating rod 12 passed through is fixed is fixed via the link 9.

A mounting block 13 is fixed to the elevating rod 12 protruding above the sliding guide pipe 4, and a protection pipe 14 loosely fitted to the sliding guide pipe 4 is fixed to the block 13. The mounting block 13 has a first arm 15 to which a push rod for pressing the object to be packed in the packaging bag a stopped at the first pressing station IV is fixed, and a machine frame 17 which is a main part of the present invention. The arm 16 is fixed. The machine frame 17 has the configuration illustrated in FIG. 4, and is constructed in a small quadrangular shape by using a vault nut or the like, and the second arm 16 is fixed to the upper frame piece 18, and the upper surface of the lower frame piece 19 (inside the machine frame) ), The air-type vibrator 20 is fixed, and the push bar 21 that presses the object b to be put into the packaging bag a stopped at the second pressing station V is fixed to the lower surface thereof. The push rod 21 is composed of a center rod 22 having a sharpened lower end and a push piece 23 that reaches near four corners of the packaging bag a.

FIG. 5 shows a pressed state of the object to be encapsulated b in the packaging bag a by the push rod 21 illustrated in FIG. 4, and a sharp portion of the center rod 22 is used to fill an inert gas in the next step. A thin bottomed hole c is formed to allow a thin gas tube to pass near the bottom of the packaging bag a. The pressing piece 23 compresses the object b to form a compression layer d in which the contained air is removed.

[0010]

[Effect of device]

 In the present invention, as described in the section of action, since the object b to be packed in the packaging bag a is compressed, it is possible to not only effectively destroy the air contained in the object but also to press the vibrator 20. The rod 21 is attached to the machine frame 17 attached to the second arm 16 that moves up and down together with the lifting rod 12, and the vibrator 20 or the push rod 21 is not moved up and down independently. There are various effects such that the mounting space for the push rod 21 can be obtained in one machine frame 17, and the drive monitoring of both can be facilitated.
