Abstract

PURPOSE: A complex gripper-type bag packing machine is provided to considerably improve the operation efficiency of the bag packing machine, to secure compatibility for a packing process and a packing size, and to obtain the competitive price of finished goods by cutting down the cost for packing by increasing packing speed. CONSTITUTION: In a rotary-type bag packing machine mounted with left and right rotary grippers(11,12) symmetrical to each other at the periphery of a rotary body(30) and being in a pair, a complex gripper-type bag packing machine is installed with an intermediate gripper between the left and right rotary grippers and packs two bags to the left, right, and intermediate grippers at the same time. The intermediate gripper comprises a lever box(26) combined and connected to a protruded part(31) formed at the body; a driving lever(28) formed with rollers(29) at both ends and rotatively installed to the lever box; and a cylinder(22) embedding a rod(23) having a rod flange and a head(21) at both ends, respectively, and a spring(24) covering the rod. The end of the cylinder is fixed to the lever box. The head is exposed out of the cylinder and reciprocated along a central axis of the rod to the rotation of the driving lever. The head is closely contacted to the front end of the cylinder by elastic force of the spring acting on the rod flange when the external force of the driving lever is removed.

Description

Compound gripper bag packing machine {COMPOSITE GRIPPER TYPE BAG FILLING MACHINE}

The present invention relates to a rotary bag packing machine in which a plurality of rotary grippers are symmetrically paired around a rotating main body, and is provided between a pair of rotary grippers forming a pair. By adding an intermediate gripper consisting of a cylinder and a head, two sets of bags can be processed simultaneously with a set of grippers.

Powdered or liquid products that are mass-produced such as food, detergents or drugs are packaged and distributed in containers made of glass, metal or synthetic resin, or paper or synthetic resin bags. Bags with smaller sieves are increasingly preferred.

In particular, due to the seriousness of environmental pollution caused by packaging containers that have recently been discarded, refill goods that purchase only the packaged products in the form of bags or packs and use only the contents in the containers used are filled. As the demand for such a rapid increase, the need for an efficient and fast bag packing machine is urgently needed.

In general, the bag-type packaging is performed through the process of opening the bag inlet, securing the filling space through the injection of compressed air into the bag, filling the contents, sealing and sealing the seal, and printing the expiration date. As shown in FIGS. 1 and 7, a plurality of grippers 11 and 12 are installed, and a rotary bag packaging machine may be automated.

The rotary bag packing machine has a left rotating gripper (11) and a right rotating gripper (12) which are symmetrically paired with each other around the main body (30) which rotates. Both sides of the packaging bag 40 are captured by 11 and 12 and the packaging is made while moving in each process as the main body 30 rotates.

However, such a conventional bag packing machine can accommodate only one packing bag 40 in a set of grippers composed of a left gripper 11 and a right gripper 12, which may limit the processing speed. There was no.

The present invention has been made in view of the above-described problems, and by installing the intermediate gripper 20 in the left and right rotating gripper 11 and the right rotating gripper 12, these left and right rotating grippers 11 and 12 and the intermediate gripper are provided. It is to be able to process two packaging bags 40 at the same time with a set of grippers composed of (20).

In addition, the intermediate gripper 20 can be detached and attached to the main body 30 as necessary to efficiently cope with the dimensional change of the packaging process or the packaging bag 40.

The detailed structure and operation principle of the present invention will be described with reference to the accompanying drawings.

2, the intermediate gripper 20 is installed between the left pivot gripper 11 and the right pivot gripper 12 provided around the main body 30. As shown in FIG. The grippers 11 and 12 and the intermediate gripper 20 are operated in a pair.

3 and 4 illustrate a group of grippers 11, 12, and 20, and the main body (eg, the left and right rotating grippers 11 and 12 are symmetrical with each other and rotates the gripper rotating shaft 13 about an axis). 30, and the intermediate gripper 20 constituted by the cylinder 22, the head 21, and the like is installed on the bisector formed by the left and right pivotal grippers 11 and 12, and formed on the main body 30. It is configured to be detachable by being coupled to the protrusion 31 through the fastening screw 27.

The left and right pivoting grippers 11 and 12 are configured as four-links, as shown in FIG. 5, and operate as tongs, and the gripper pivoting shaft 13 is rotated about an axis to the size of the packing bag 40. According to the gripper interval can be adjusted.

As shown in FIG. 4, the intermediate gripper 20 includes a cylinder 22 in which a rod 23 and a spring 24 are embedded, a lever box 26 in which a driving lever 28 is built, and the main body 30. Protruding portion 31 formed in the) is coupled to the lever box 26 and the fastening screw 27 is fastened thereto so that it is fixed to the main body 30.

In addition, as shown in FIG. 6, both ends of the rod 23 are configured with a head 21 and a rod flange 25 so that the rod 23 is rotated as the driving lever 28 installed in the lever box 26 rotates. When the external force acting on the driving lever 28 is removed, the head 21 comes into close contact with the tip of the cylinder 22 due to the elasticity of the spring 24 acting on the rod flange 25.

Both ends of the drive lever 28 are provided with a roller 29 that rotates freely so that a force in the vertical direction is always applied to the contact surface of the rod flange 25 or the like.

As shown in FIG. 6, the operation of the driving lever 28 is performed through an actuator 32 and a pivoting plate 33 installed below the main body 30. The driving means such as the actuator 32 is Those skilled in the art to which the present invention pertains are matters that can be easily changed and applied according to the packaging process, and thus no specific limitations on the claims are made.

7 and 8 are the operation state diagram of the conventional bag packaging machine and the operation state diagram of the present invention, respectively, in the present invention in which the middle gripper 20 is installed, two packaging bags 40 can be processed at the same time, which is superior to the conventional one. It can be seen that the packaging of speed is possible.

In addition, Figure 9 is the present invention with the intermediate gripper 20 is removed, the large size packaging bag 40 can be processed without additional equipment.

As a result, the technical gist of the present invention is a rotary bag packer in which a left rotating gripper 11 and a right rotating gripper 12 are symmetrically paired around a rotating main body 30. The intermediate gripper 20 is provided between the left pivotal gripper 11 and the right pivotal gripper 12 so that one left pivotal gripper 11, the middle gripper 20, and the right pivotal gripper 12 can be connected simultaneously. A compound gripper bag packaging machine characterized in that two bags are captured,

The intermediate gripper 20 includes a lever box 26 coupled to and fastened to the protrusion 31 formed on the main body 30, and a roller 29 formed at both ends thereof and rotatably mounted to the lever box 26. 28 and a rod 23 having a head 21 and a rod flange 25 formed at both ends and a spring 24 surrounding the rod 23, and one end of the cylinder 22 fixed to the lever box 26. The head 21 is reciprocated along the central axis of the rod 23 as the drive lever 28 is rotated to the outside of the cylinder 22, the external force on the drive lever 28 is removed, the rod flange The composite gripper bag packing machine is characterized in that the head 21 is in close contact with the tip of the cylinder 22 by the elasticity of the spring 24 acting on (25).

Through the present invention can not only significantly improve the operation efficiency of the bag packaging machine, but also ensure the compatibility of the packaging process and the standard of the package, it is possible to reduce the packaging cost by improving the packaging speed, the price competitiveness of the final product A great effect can also be obtained.
