Description

Rotary type automatic packing apparatus {A rotary type automatic packing apparatus}

The present invention relates to a rotary type automatic packing machine, and more particularly, to a rotary type automatic packing machine which is capable of absorbing only the packing bags positioned at the uppermost part from the packaging bags which are improved in productivity and are stacked obliquely and supplied to the gripper. .

In order to utilize the space more efficiently and improve the mass production of the product, the table is intermittently stepped along the defined arc trajectory to perform a series of processes related to the packaging of the product. Rotary type automatic packaging machines are known.

Rotary type automatic packing machine puts packing container such as pouch into the packing machine, and then a series of processes such as supplying the packing container, weighing the contents to be packed, filling the contents in the container, and sealing the container opening are performed step by step along the arc of the arc. It adopts automatic operation.

In other words, the rotary type packaging machine starts with the process of holding a packaging container such as a pouch in a gripper, and then opens the opening of the packaging container to fill the contents in the held packaging container. The process of filling the contents through the filling nozzle, sealing the inlet of the packaging container using a sealing bar after filling the contents, and cooling the inlet of the sealed packaging container to complete the packaging is one step. It has a structure that is sequentially performed on a table that rotates intermittently.

The rotary type packaging machine includes a single type in which one packaging container is processed in one step and a dual type in which two packaging containers are simultaneously processed in accordance with an intermittent table rotation. Single type is suitable for heavy packing of relatively heavy weight, but only one packing container is carried out in one step, so overall product productivity is inferior, whereas dual type has multiple packing containers in one step. It has a structure that can be processed for packaging, so it is very suitable for mass production of a variety of varieties, and thus has been widely used in the packaging industry recently.

Figure 1 shows a conventional rotary packaging machine of a single type, vertically supported by the gripper (2b) provided on the turntable 10, each packaging bag (P) supplied through the packaging bag supply unit (a) In the state, by rotating the turntable 10 to fill the contents in the packaging bag (P) through the contents filling unit (b), and then continue to rotate the turntable 10 to hot seal the inlet of the packaging bag and then gripper the packaging bag Drop it out and take it out.

2 is a view schematically showing a conventional dual type rotary baler, the conventional dual type rotary baler converts the lifting and lowering of the roller relative to the cam surface to the swinging motion of the gripper suitable for holding the packaging container and opening the packaging bag (P). Based on the rotary table 10 equipped with various link mechanisms, the gripper 2 has a structure in which a plurality of sets are installed along the circumferential surface of the rotary table 10 at regular intervals.

Here, the gripper 2 has two movable grippers 2b mounted on both sides of the fixed gripper 2a so as to be interlocked with each other so that two bleachers P can be positioned at one station. Therefore, two movable grippers spaced apart from each other by the fixed gripper by the rotary table 10 are moved by one step, and the packaging process for the two packaging bags P held therebetween is simultaneously performed. It is a structure that can be.

As described above, a dual type rotary type packaging machine employing a fixed gripper 2a is provided to process two packaging bags in one step from a single type in which one packaging bag is processed in one step, but the following prior art documents As described above, further development of processing two packaging bags by using one rotary table 10 is in no progress.

On the other hand, in the single type or dual type rotary packaging machine, the configuration of the supply unit (A) for supplying the packaging bag (P) to the gripper (2), as shown in Figure 3, the packaging bag (P) is laminated The packaging bag P is sucked up by the vacuum cup 22 from the cartridge 20 accommodated therein, and then lifted up and captured by the capture device 30.

The vacuum cup 22 is connected to a vacuum ejector via a pneumatic hose 21 and is mounted on an adsorption device including a lever shaft 11, a lifting rod 12, and a suction support 13, and packaging Bag (P) is composed of a synthetic resin through which no air flows, the suction force is generated when the vacuum cup 22 is in contact with the surface of the packaging bag (P) loaded on the top, vacuum packing bags (P) adsorbed one by one When the cup 22 is slightly lifted up, the packaging bag P is captured by the capturing device 30 interlocked with the vacuum cup 22 and supplied to the gripper 2.

If the capture process is optimally operated, the suction force acts on only one package bag (P) loaded on the top when the package bag (P) is adsorbed by the vacuum cup (22). Only one packaging bag P is captured.

However, between the loaded packaging bags (P), moisture or static electricity occurs during handling, and as shown in FIG. 4, as shown in FIG. 4, a plurality of packaging bags (P) are captured in one operation. It leads to defects, such as loss of the packaging bag (P) and the loss of the contents are often generated, causing significant problems in the packaging operation.
