Description

A system for multiple bundle packaging of back-packed products using transporting devices of changeable belt type}

The present invention relates to a bundle packaging system, and more particularly, to a bundle packaging system using a variable belt-type lateral transfer device.

It is common to see that various products such as dumplings, ramen, snacks, and sausages are sold in bundles of two, three, or four. Such bundled sales are generally applied to bagged products using plastic bags as packaging materials.

The bundle packaging method includes a tape bundle method in which bagged products are wrapped in bundle units such as 2, 3, or 4 with strip tape, or a double packaging bundle in which bagged products are packaged in bundle units with plastic bags for bundles. method is being used.

However, as regulations on double packaging sales are being strengthened, the tape bundle method is expected to be more commonly used than the double packaging bundle method. Accordingly, efforts are being made to convert the strip tape bundling work from the existing manual method to an automated method, centering on large marts.

Korean Patent Registration Publication No. 10-1901647 (2018.09.28) introduces an automatic stacking system for bag packaging products to which a strip tape bundle method is applied, and Korean Patent Registration Publication No. 10-1916011 (2019.01.30) An automatic taping system for bagged packaging products to which the tape bundle method is applied has been introduced.

The ends of the strip tape are held between the upper roller 113 and the lower roller 115, and the holding modules 110A and 110B are driven in the state where the strip tape is held, thereby attaching the strip tape to the object. .

The discharge line comprises one or more conveyor belts (8). In the example of FIG. 1, the discharge line is illustrated as being composed of one conveyor belt 8, but the number of conveyor belts 8 may be changed to two or three.

2. Operation of the bundle packaging system

7a to 7e are views sequentially showing the operation of the bundle packaging system. With reference to this, the operation of the above-described bundle packaging system will be described.

Referring to FIG. 7A, two sets of objects P1 and P2 supplied along the X direction through the supply device 10 are pushed in the Y direction by the pushing device 1, and two sets of distance adjusting transfer devices 20A , 20B). The illustrated example shows a case where the objects P1 and P2 of each set are composed of five individual objects, and the five individual objects constituting each set pass through the guide member 4 while the sides are in close contact with each other. It is put into the adjustable transfer devices 20A and 20B. The distance adjustment conveying device (20A, 20B) is driven based on the detection signal of the product detection sensor (5C) (see Fig. 1) through which the two sets of objects (P1, P2) have a preset interval.

Referring to FIG. 7B, two sets of objects P1 and P2 are attached as shown in FIG. It is transferred to the work position, and at this time, the objects P1 and P2 maintain the previously set interval. This interval is the interval at which the two sets of bundle objects P1 and P2 are placed in the correct attachment working position.

Referring to FIG. 7C, when the bundle objects P1 and P2 are placed in the attachment operation position, the compression devices 50 descend to press and fix the front and rear ends of the bundle objects P1 and P2. In addition, the distance between the driven rollers 72 and 73 is narrowed by the operation of the above-described lifting mechanism 83, so that the distance between the three sets of variable belt type side transfer devices 30A, 30B and 30C is the distance at which the attachment operation is possible (d ) is extended to By expanding the interval, the attachment device 60 grips the strip tape T, handles it upward, and attaches it to the objects P1 and P2 to bundle the objects P1 and P2.

Referring to FIG. 7D, after the interval expansion, the two attaching units 110 provided in the attaching device 60 operate simultaneously, so that the two sets of objects P1 and P2 are attached using the strip tapes T. Bundling is performed at the same time.

Referring to FIG. 7E, when the bundle packaging is completed, the return operation of the compression device 50 and the initial state return operation of the side transfer devices 30A, 30B, and 30C are performed, and then the side transfer devices 30A, 30B, and 30C As the belts are driven to rotate, the bundled objects P1 and P2 are transferred to the discharge line and discharged to the outside through the conveyor belt 8 provided therewith.

8 is a view showing an example of an object P bundled by the system of the present invention. As shown therein, according to the system of the present invention, the object P may be bundled in a manner of enclosing it with a tape. Ramen can be cited as a representative object (P) to which the present invention can be applied, but the present invention can be applied to various products without being limited thereto.

In the above description, an example of simultaneously performing bundle packaging for two sets of objects (P1 and P2) has been described, but the system of the present invention can be applied for the purpose of simultaneously bundling more objects such as 3 sets and 4 sets. there is.
