Description

[Detailed description of the invention] (Purpose) The present invention consists of several pairs of gripping arms, which are controlled to grip and release the packaging bag a, and approach and separate from each other, on an intermittent rotating rotary plate, and the gripping arms. In an automatic packaging device equipped with gas filling pipes having the same number of logarithms of arms and entering and exiting from above the packaging bag a, the filling position is provided at the filling position and overlaps with the rotational movement path of the packaging bag and the gas filling pipe during filling. The filling funnel, which must be placed in the packaging bag, is retracted to the upper side of the rotary movement path except when filling, so that the gas filling pipe 5 does not collide with the filling funnel during intermittent rotation of the rotary plate. It is an object of the present invention to provide a filling device which can smoothly fill the packaging bag and which does not cause any trouble in the intermittent rotational movement of the packaging bag and the gas filling tube by the rotary plate.

The filling device installed in conventional automatic packaging equipment is
A filling funnel is installed in the passage of the packaging bag that rotates with the rotating plate, and the funnel is retracted upward as soon as filling is completed. In models equipped with a filling tube, unless the filling funnel is retracted significantly above the rotary plate, the gas filling tube, which also protrudes above the rotary plate, will collide with the rotating plate when rotating together with the rotary plate. The present invention can eliminate this drawback of collision.

Embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a plan view showing the outline of an automatic packaging device 1, in which a circular rotary plate 4 of intermittent rotation is attached to a shaft 3 at the center of a fixed table 2. A large number of pairs of gripping arms 5 are provided whose gripping and releasing of the vertical edges on both sides of the packaging bag a and their approach and separation from each other are controlled. Also, the rotating plate 4 has a gripping arm 5.
The same number of gas filling pipes 6 as the number of pairs of gripping arms are installed, the gas filling pipes 6 being controlled to enter and exit from above the packaging bag a gripped by the gripping arms.

The rotary plate 4 rotates intermittently by stopping five pairs of gripping arms at a number of stations, and rotates intermittently to determine the opening position of the packaging bag a, the packaging material filling position, and the packaging bag a.
The tension position, primary welding position, secondary welding position, etc. Pull it upwards in between.

The packaging bag a and the gas filling tube 6, whose longitudinal edges on both sides are gripped by the gripping arms 5, pass through a circular rotational movement path 7 by the rotary plate 4 while stopping at each of the above-mentioned positions.

At the filling position, there is a filling guiding funnel 8 for the packaged material whose position is fixed, and a drop opening 9 of the funnel 8 is connected to an upper opening 11.
A filling funnel 10 is inserted slightly into the filling funnel 10, and a guide tube 19 is provided near the drop opening 12 of the filling funnel 10, which penetrates from the bottom to the top of the fixed table 2.
Reversible rotating rod 13 that can freely rotate and slide up and down.
Attached to the arm rod 13a protruding from the reversible rotary rod 1
3 as the center, the filling angle of the solid line is such that the drop port 12 matches the path 7 of the packaging bag a, and the drop port 12 is aligned with the path 7 of the packaging bag a.
Rotate and move to any of the retraction angles indicated by the dashed lines. The drop opening 9 of the filling guide funnel 8 is located within the widened upper opening 11 of the filling funnel 10 at any angle and does not abut against the edge of the upper opening 11.

A collar 14 is fixed to the lower end of the reversible rotary rod 13 below the fixed table 2, and an arm 15 protruding from the collar 14 is connected to a swing rod 16 for controlling the rotation between the solid line angle and the chain line angle. Furthermore, the tip of an elevating lever 18 protruding from the rotating shaft 17 that moves reversibly is connected to the lower end of the elevating rod 13. The swing rod 16 and the rotating shaft 17 are connected to the rotating plate 4.
It operates at a timing synchronized with the intermittent rotation of the rotary plate 4 by a cam type (not shown) rotated by a motor etc. that drives the drive system of the filling funnel 10.
is inserted a little into the opening b of the opened packaging bag a, as shown by the chain line in FIG. 20 is a mounting collar of the guide tube 19.

To explain the operation of this embodiment, a pair of gripping arms 5
While the packaging bag a is stopped at the opening position, both sides of the bag are attracted by the suction cups 21, 21, and due to the approach of the gripping arms 5 and the suction, the bag opening b is opened and the bag is moved to the filling position and stopped. do. In time with this stop, the filling funnel 10, which had been pushed up by the lifting lever 18 and moved to the retracted position, returns to the passage 7 in conjunction with the reversible rotating shaft 13 that rotates due to the operation of the rod 16. The bag is moved above the bag mouth b, and then the lifting lever 18 lowers the reversible rotary rod 13 by rotation of the rotary shaft 17, and the drop opening 12 of the filling funnel 10 is placed into the opening of the bag mouth b. A fixed amount of packaging material is supplied to the filling guide funnel 8, and is filled into the packaging bag a from the drop port 9 through the top port 11 and drop port 12 of the filling funnel 10. The lever 18 pushes up the reversible rotary rod 13, and then the rod 16 is actuated, and the filling funnel 10 escapes the drop opening 12 upward from the bag opening b and rotates to the retracting angle. On the other hand, the rotary plate 4 rotates intermittently in time with the evacuation movement, moves the filled packaging bag a to the next position, moves the opened packaging bag a to a new filling position, and stops. do.
Subsequent operation of the filling funnel 10 is repeated as described above.

(Effects) As described above, the present invention has a structure in which the gas filling pipe 6 and the packaging bag a are intermittently rotated by the rotary plate 4 without raising or lowering the filling funnel 10 significantly. The reversible rotary rod 13 to which the funnel 10 is connected is pushed up by the lifting lever 18 to allow the funnel 10 to escape slightly from the upper opening of the packaging bag a, and further rotation of the reversible rotary rod 13 moves the filling funnel 10 into the packaging bag a. The retraction angle is such that the gas riser pipe 6 moves laterally from above the upper opening, thereby retracting the gas riser pipe 6 upwardly and laterally from the rotational movement passage 7, so that the packaging bag a and the gas filling pipe 6 do not collide with the filling funnel 10 at all. This is to prevent the packaging bag a and the gas filling tube 6 from rotating in the passage 7 along with the intermittent rotation of the rotary plate 4.
When the intermittent rotation is finished, the reversible rotating shaft 13 moves the filling funnel 10 slightly above the filling position that matches the rotational movement passage 7, and the lifting lever 18 moves the reversible rotating rod 13 and the filling funnel 13. is lowered and the drop opening of the funnel is inserted into a new packaging bag a which has been opened as described above to be placed at the packaging bag filling position.This causes the gas filling pipe 6 to attach to the filling funnel 10. It has the effect of being able to rotate and move without hitting anything.
