Description

Bag packing machine having a rotating filling nozzle {Bag packing machine having swivel type filling nozzle}

The present invention relates to a bag packaging machine having a rotating filling nozzle, specifically, a bag-shaped packaging container containing a refilling detergent, etc., attached to a rotating table and rotating at a constant speed while continuously filling the contents and rapidly returning them. It relates to a back packer having a rotating filling nozzle.

In general, a stand-up bag is mainly used as a refillable packaging container for filling liquids such as juice, detergent, shampoo, and the like. Packaging machines are widely used. According to such a back packer, the bag is fixed to a gripper mounted on a table that rotates intermittently by one step. After filling the contents, and after the filling is completed, the table is rotated one step further to seal the opening of the bag using a seal bar (seal bar).

According to the method in which the table is filled with the contents and sealed in the bag while the table rotates once in an intermittent manner, the table is intermittently rotated, gripping the bag into the gripper, opening the bag opening, and the contents in the bag. In the filling step and sealing the inlet of the bag, the operation of the table must be stopped only when the rotation of the table is stopped. Therefore, the stop time is about 2/3 and the rotation time is about 1/3 of the rotation time of the table, and the stopping time is longer than the rotation time of the table and the time to fill the contents in the bag is too short, so that the amount of the packaging bag is limited. It must be.

In order to increase the output of the packaging bag in such a conventional apparatus, it is necessary to increase the rotational speed of the table, increase the discharge pressure per unit time of the filling nozzle, or increase the nozzle size. However, if the rotation speed is increased, the contents of the packaging bag may fluctuate due to the inertia, and the speed is limited. If the discharge flow rate of the nozzle is too fast, the contents may pop out of the packaging bag. It is determined by, so it must be limited. Therefore, according to the conventional intermittent rotary packaging machine, there is a limit on the production of the packaging bag under such a restriction condition. In the case of the single type processing the fabric softener (capacity 1300 ml) one by one, about 30 bags per minute and two bags are processed. The twin type has a problem of low productivity because it can only pack about 50 bags per minute.

In addition, unlike the prior art while rotating the table, there is no back-packing device for filling the contents into the packaging bag even during rotation.

The present invention has been devised in view of the above-described problems, and the bag is filled with contents even while the rotating movement is made while rotating the constant time at a constant speed with the intermittent rotating table without fixing the charging nozzle for filling the contents in the bag. After the completion of the object, the filling nozzle is rapidly returned to its original position, and the object of the present invention is to significantly improve the packaging speed of the bag. The present invention can also be charged during the movement as well as stop time to reduce the stop time per cycle and to extend the rotation time, it is possible to improve the filling speed of the packaging bag.

It is preferable to rotate the filling nozzle 50 by rotating the rotating shaft 52 forward and reverse while moving left and right.

In the back packer of the present invention, the rotation means 60 may be a servo motor connected to the rotation shaft 52 of the filling nozzle.

In addition, in the back packer of the present invention, the rotation cam 64 is a radius increasing portion that continues from the constant radius (R1), the constant radius (R1) constant radius relative to the rotation center, the rotation radius gradually increases (R2) and a radius reducing portion R3 between the constant radius portion and the radius increasing portion and gradually decreasing in radius from the radius increasing portion.

A connection bar 78 mounted and rotatably connected to the rotation shaft 52, and a spring 79 connected to the pivot support 72 on the opposite side of the lifting cam 74 to push the support toward the lifting cam. Thus, it is preferable that the pivot support 72 elevate the rotating shaft 52 while the pivot support 72 pivots like a seesaw by the rotation of the elevating cam 74.

In addition, the small radius (R0) of the elevating cam (74) may have a length for supporting the pivot support 72 so that the rotary shaft 52 is in the lowered state.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view of an intermittent rotary packaging machine according to the present invention, which is a schematic view for explaining the overall process of the present invention, particularly the filling process, and has the same configuration as a conventional rotary packaging machine except for the related parts of the filling nozzle.

As shown, the intermittent rotary table 10 is intermittently rotated in the direction of arrow A as in the conventional apparatus, and has a plurality of bag grippers 11 around it, and a bag feeder 1 installed around the table. The bag 20 is attached to the two grippers 11. When the table 10 to which the bag 20 is attached rotates, the bag 20 is positioned below the nozzle-type filling nozzle 50 according to the present invention.

As will be described later, the filling nozzle 50 is configured to enable the up / down and forward / backward rotation in accordance with the intermittent rotational movement of the table 10. Therefore, when the bag 20 is located below the filling nozzle 50 and stops, the filling nozzle 50 descends and enters into the gap opening of the bag 20 (see FIG. 2). In this state, the filling nozzle 50 rotates in the direction of the arrow B together with the table 10 at the same speed as the table 10 rotates one step. As the filling nozzle 50 rotates, the contents of juice or shampoo are completely filled in the bag 20. After the charging is completed, the charging nozzle 50 is raised from the table 10. As the filling nozzle 50 rises, it rotates in reverse and rapidly returns to its original position. During this time, the table 10 rotates one step and then stops to proceed to the next sealing process. At this time, the charging nozzle 50 returned to its original position is lowered back to the inlet of the empty bag 20, and the above-described process is repeated.

Figure 2 is a schematic cross-sectional view of the filling nozzle according to the present invention, a configuration diagram for explaining the above-described lifting nozzle 50 charging means.

As shown, the rotating shaft 52 of the filling nozzle 50 is preferably arranged coaxially with the rotating shaft 12 of the table 10. Then, the filling nozzle lifting means 70 according to the present invention is provided in the box below the table 10. The filling nozzle lifting means 70 may be hydraulic, pneumatic, or the like, but it is preferable to use a cam driving method. Moreover, the filling nozzle rotating shaft 52 coaxially arranged with the table rotating shaft 12 is comprised so that it may rotate independently of the table rotating shaft 12 using a means, such as a bearing.

The filling nozzle lifting means 70 is an elongated pivot lever 72, a brace 76 pivotally supporting the middle of the pivot lever 72, and a cam 74 mounted in contact with the right end of the pivot lever 72. ), A spring (79) for pushing the pivot lever (72) toward the cam, a bracket (78) connected to the lower end of the filling nozzle rotation shaft (52) rotatably in a c-shape, and connected to the other end of the pivot lever (72). (See FIG. 4).

The operation principle of the filling nozzle lifting means 70 configured as described above will be described.

While the cam 74 rotates and the small diameter portion rotates in contact with the pivot lever 72, as shown by the solid line in FIG. 2, the rotating shaft 52 is in the lowered state. When the cam 74 is further rotated so that the large diameter portion comes in contact with the lever 72 and the right end portion of the lever 72 is lowered, the left end portion of the lever rises, as shown by the imaginary line in FIG. As a result, the filling nozzle 50 rises. That is, as the cam 74 rotates, the filling nozzle 50 repeatedly moves up and down. Therefore, as described above, by adjusting the size and rotation radius of the cam 74, it is possible to raise and lower the filling nozzle in accordance with the intermittent rotation step of the table 10, the small radius (R0) of the cam 74 is the rotation axis ( It is desirable to support the pivot lever 72 so that the 52 is in the lowered state.

On the other hand, in general, the filling nozzle 50 enters the inlet of the packaging bag 20 as described above, and discharges the contents. Therefore, it is preferable that the filling nozzle 50 be rotated back after being raised, depending on the type of packaging bag. The nozzle may not need to be inserted into the opening of the bag. Therefore, according to the type of packaging bag, it is also included in the scope of the present invention that the charging nozzle is rotated forward and reverse without immediately moving up and down the charging nozzle described above.

3 and 4 are partial side and plan views, respectively, of the charging nozzle rotating means 60 for adjusting the forward and reverse rotations of the charging nozzle 50 described above.

As shown in Figure 3, the rotating shaft 52, the rotation means 60 is in contact with the side of the pivot rod 62, the long pivot rod 62 is pivotally mounted spaced apart from the rotation shaft 52 Rotatable rotating cam 64, a rotary bar 66 mounted on the rotary shaft 52 to rotate together with the rotary shaft 52 at the lower end of the rotary shaft 52 and protruding a predetermined length, the rotational force of the pivot rod 62 In order to deliver the to the pivoting bar 66, one end is pivotally connected to one end of the pivot rod 62 and the other end is connected to one end of the pivoting bar 66 so as to be pivotable. It is composed of a spring 69 mounted on the pivot rod 62 to push the pivot rod towards the cam 64 (see FIG. 4).

The operating principle of the rotating shaft rotating means 60 configured as described above is as follows.

As the cam 64 rotates, the pivot rod 62 rotates left and right. When the pivot rod 62 rotates to the left and right, the connecting rod 68 connected to one end of the pivot rod 62 moves to the left and right, and the rotation bar 66 connected to the other end of the connecting rod 68 is indicated by the arrow C. To rotate left and right in the direction (see FIG. 4). That is, when the pivot rod 62 is rotated from the position shown by the solid line in FIG. 3 to the position shown by the virtual line by the rotation of the cam 64, one end is connected to the pivot rod 62 so that rotation is possible. The rod 68 is moved to the right side in FIG. 3, whereby the pivoting bar 66 (see FIG. 4), which is mounted on the rotating shaft 52 and rotatably connected to the other end of the connecting rod 68, is And pulled to the right in FIG. 4 by the connecting rod 68 moved to the right, and rotated from the position shown by the solid line in FIG. 4 to the position shown by the imaginary line. Similarly, when the pivot rod 62 is rotated from the position shown by the virtual line in FIG. 3 to the position shown by the solid line by the rotation of the cam 64, the connecting rod 68 moves to the left side in FIG. As a result, the pivoting bar 66 (see FIG. 4) is pushed to the left side in FIG. 4 by the connecting rod 68 moved to the left side and is shown as a solid line from the position shown by the virtual line in FIG. 4. As described above, when the cam 64 rotates, the rotating bar 66 rotates left and right, so that the rotating shaft 52 on which the rotating bar 66 is mounted is rotated. 66) and repeat the forward and reverse rotation. Therefore, as described above, by adjusting the size and diameter of the cam 64, the filling nozzle 50 can be rotated forward to match the rotational speed of the table 10, and can be reversed at a faster speed to the original position. have. That is, in the illustrated state, if the rotation radius of the cam 64 is constant, the charging nozzle is not rotated by the cam, so the charging nozzle is in a stationary state. When the rotation radius of the cam increases, the charging nozzle is in accordance with the rotation of the cam. When the rotation radius of the cam decreases in forward rotation, the charging nozzle rotates in reverse as the cam rotates. Accordingly, the cam 64 has a constant radius R1 having a constant radius of rotation based on the center of rotation, a radius increasing portion R2 in which the radius of rotation gradually increases from the constant radius portion, and a radius gradually decreasing from the radius increasing portion. It is preferable that it is composed of a radius reducing portion (R3). In addition, in order to make reverse rotation speed larger than forward rotation speed, the radius reduction rate of the said radius reduction part should just be larger than the radius increase rate of a radius increase part. Then, the rate of increase and decrease of the radius may be adjusted to the rotational speed of the table 10.

The two cams 64 and 74 described above control the rotation and lifting of the filling nozzle. The cams rotate forward at the same speed as the table 10 in the state where the filling nozzle 50 is lowered, and the table when the filling nozzle is raised. Most preferably, it is arranged to reverse rotation at a faster speed than (10).

On the other hand, according to the present invention, as described above, it is most preferable to rotate the charging nozzle forward and reverse using the rotating cam, but other means than the rotating cam may be used. For example, it is also within the scope of the present invention to rotate the rotation axis of the charging nozzle forward and reverse by using a servo motor (not shown).

The drawings and specification are merely exemplary of the invention, which are used for the purpose of illustrating the invention only and are not intended to limit the scope of the invention as defined or in the claims. The filling nozzle for filling the bag is rotated with the table to fill the contents, and after the filling is completed, the packaging machine with the filling nozzle rapidly returned to the original state will be included in the scope of the present invention.

According to the packaging machine equipped with the rotational charging nozzle according to the present invention configured as described above, the stopping time and the rotating time can be arranged almost in half compared to the stopping time 2/3 and the rotating time 1/3 of the conventional packaging machine. By reducing the speed and minimizing the inertia of the contents in the packaging bag, the contents can be filled during the rotation. Thus, the productivity is improved by almost 50% or more.
