DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product using a seasoning or the like by cutting and separating one bag or a plurality of required bags from a continuous packaging bag filled with a seasoning, a soup or the like. The present invention relates to a method of connecting continuous packaging bags suitable for use in automatic repackaging and a device used therefor, which makes it possible to extremely easily and quickly connect the continuous packaging bags to each other, and to position the continuous packaging bags at the connecting position. The re-separation is always assured, and in addition, the possibility that the connecting tape or other foreign matter is mixed in the packaging bag of the product is completely removed.

[0002]

2. Description of the Related Art For example, a food maker who repacks a packaging bag filled with a seasoning or the like together with a product using the same often packs a plurality of seasoning packaging bags with the product according to the quantity of the product. is there. In such cases,
In general, food manufacturers produce seasoning packaging bags in a number corresponding to the quantity of their own products packaged in one bag in advance, and seasoning packaging bags such as double packaging and triple packaging are seasoned. They are purchased from food manufacturers, seasoning filling processors and others, or are produced in-house.

[0003] However, this means that it becomes necessary for the food manufacturer to prepare in advance a seasoning packaging bag of a type corresponding to the specification of its own product quantity and having a different number of serial packages. There was a problem that the inventory management of bags was troublesome. Also, in order to fit seasoning packaging bags such as two-pack or three-pack to suit the automatic packaging of their own products, many seasoning packaging bags of each number packed in cardboard boxes are delivered. However, there is also a problem in terms of man-hours in that it is necessary to take out of the cardboard box as required by a worker's manual work and set the packaging bags in an automatic machine in a state of being aligned.

[0004]

2. Description of the Related Art In order to solve such a problem of the prior art, the applicant has previously disclosed in Japanese Patent Application No. Hei 4-302037, cutting an arbitrary continuous packaging bag from one long continuous packaging bag. A device that can be separated was proposed. This apparatus is provided with a feeding means for a continuous packaging bag having perforated holes or surface scratches in units of one packaging bag, and a counting means for counting the number of packaging bags passing through the feeding means is provided. Further, a rod-shaped member which performs translation or rotation based on a signal from the counting means and collides with the continuous packaging bag is provided. According to this device, while feeding out the continuous packaging bags by the feeding means, for example, the number of packaging bags that have passed through the feeding means is counted by the counting means, and after the passage of the required number of packaging bags is detected, the rod-shaped member is detected. By activating and colliding it with the perforated wound position of the continuous packaging bag or a position near the perforated wound, it is possible to cut and separate the required number of continuous packaging bags from the continuous packaging bag by the impact. Becomes

[0005] Therefore, according to such an apparatus, the food maker only needs to prepare one type of continuous packaging bag such as a seasoning provided with perforated scratches for each packaging bag, and it is possible to provide a continuous packaging as required. The number of packaging bags can be appropriately cut and separated from the continuous packaging bags. Therefore, the food maker has an advantage that, for example, the inventory management of the seasoning packaging bags becomes extremely easy, and the number of man-hours for handling the seasoning packaging bags during automatic packaging of commodities can be significantly reduced.

[0006]

By the way, in order to perform the above-described cutting and separation of the required number of continuous packaging bags from the continuous packaging bags in a sufficiently functional manner, the packaging bags are usually delivered in a cardboard box. By connecting the rear end sealing portion of one continuous packaging bag and the front end sealing portion of another continuous packaging bag in advance, without stopping the cutting device every time the continuous packaging bag is switched, Where it is necessary to operate continuously, if the connection is made with an adhesive tape that has been widely and conventionally used for connection of a packaging film, the number of work steps for connection increases. With
There was a problem that the use of an adhesive tape was indispensable.
Further, when it becomes necessary to cut and separate the packaging bag at the connection position, there is a problem that it is practically impossible to cut the packaging bag by the hitting and cutting apparatus as described above. However, when cutting at the connection position is unnecessary, the packaging bag for the seasoning and the like including the adhesive tape is repackaged with the product, and the value and appearance of the product are necessarily reduced. was there.

[0007] Here, if the cutting is performed by a cutting device using a shearing blade in order to ensure the cutting and separation of the packaging bag, it is possible to cut the connecting bag with the adhesive tape. In this case as well, the packaging bag with the adhesive tape cut by the shearing blade still attached cannot be prevented from being repackaged with the product, and moreover,
There is a high possibility that cutting chips of at least one of the leading end sealing portion and the trailing end sealing portion of the continuous packaging bag abutted or superimposed on each other are mixed into the repackaging bag.

The present invention has been made as a result of studying to solve such a problem caused by the connection between continuous packaging bags using an adhesive tape, and an object of the present invention is to provide an adhesive tape. The continuous packaging bags can be easily and quickly connected to each other with the required strength without requiring any other special connecting material, and the connection can be reliably released by the impact of the impact cutting device. In addition, even if a packaging bag of a seasoning or the like is repackaged with a product without disconnecting the connection, there is no risk of deteriorating the value, appearance, etc. of the product. To offer.

[0009]

According to the present invention, there is provided a method for connecting continuous packaging bags, comprising the steps of:
Packaging with lum and laminated sealant resin
Bag, successive number via a perforated line holes scratches or surface flaws formed in the sealing portion, a rear end seal portions of one continuous packaging bag filling and packaging the articles to be packaged, other similar continuous packaging bag per the connecting tip seal portion, after sandwiching superposed a distal sealing portion and the rear end seal portions, in its clamping portions, each of previously-rear end seal unit content, a heated pin, They are pierced while melting them . In addition, the apparatus of the present invention has two pairs of clamping means which sandwich the front end sealing portion and the rear end sealing portion in their overlapping positions .
Together have been provided, during its these clamping means, it is plugged into each of the seal portions fraction of previously-rear, it al
And a heating pin that penetrates both seal portions while melting .

[0010]

[Action] In this connecting method of continuous packaging bag, in clamping state superposition of the respective sealing portions of the above-rear, its both sealing portions of these, a heated pin causes them to melt
The Rukoto passed through narrowing stab while, in the first molten portion of the sealant resin which is laminated on the base film disposed on both sides of the packaging bag, attached to the pin, each of the seal portion adjacent to the vertical And between the base films around the through holes of the pins to function as an adhesive layer between the base films. Secondly, each of the upper and lower adjacent seal portions One side "joins" the pin in softened state
The burrs also penetrate into the other melt-softened seal part to provide a mechanical connection between the seal parts, and thirdly, the base film itself of each of the upper and lower seal parts The front and rear seals are interconnected with the required strength without disturbing the feeding of the continuous packaging bag and other handling, based on the fact that the seals are directly welded around the pins. become.

Here, the mutual connection strength of the front and rear end seal portions is appropriately increased or decreased by selecting the number of pins penetrating the both seal portions, the diameter of each pin, the cross-sectional profile of the pins, and the like. Can be done.

By the way, the two continuous packaging bags connected in this way are connected with a relatively small joining strength that does not hinder the handling of the continuous packaging bags.
When the connecting portions of the two correspond to a predetermined cutting / separating position, for example, the connecting portions can be easily and reliably broken and dissociated by colliding the rod-shaped member of the impact cutting device with the connecting portions. In addition, no connecting tape or other foreign matter remains on any of the dissociated sides.

On the other hand, the connecting portion of the continuous packaging bag is located at a position where shear separation is not required, and the continuous packaging bag is repackaged with the product without disconnecting the connection there. Even if there is, the connecting part,
Since the heat-sealed portions at the rear end are merely overlapped and joined, it is almost impossible to visually check their existence from the outside, so the value of the product and appearance etc. are impaired by the joint. It is not .

Thus, according to this method, in a state where the respective seal portions of the front and rear ends are overlapped and clamped,
By simply inserting a heated pin into these seals, two continuous packaging bags can be connected simply and quickly with the required strength without using any special connecting material. In addition, this connection can be easily and reliably dissociated as required by the impact of the impact cutting device, similarly to the perforated flaw-forming portion. Then, as a result of performing the cutting and separating by the impact cutting device reliably, it is possible to completely eliminate the possibility of generation of the seal partial cutting chips as in the case of using the shearing blade cutting device.

Further, since the connection in this case is obtained by simply overlapping and joining the respective seal portions,
Even if the seasonings, etc., as the items to be packed in the continuous packaging bag are repackaged in a state where the concatenation is broken, even if they are repackaged with the product in the connected state, Appearance is not impaired.

In carrying out the above-described method,
And clamping means of the two pairs arranged at a mutually distance, is arranged between these two clamping means are plugged into each of the seal portions fraction of previously-rear, but such let them melt
In the case of using the inventive device comprising the heating pins penetrating both seal portions, the leading and trailing end portions of the continuous packaging bag can be reliably interconnected as expected using a low-cost simple device.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing an embodiment of the apparatus of the present invention, in which 1 indicates a preceding continuous packaging bag, and 2 indicates a subsequent continuous packaging bag fed out thereafter.

Here, the invention device 3 which can be of either a portable type or a stationary type has a rear end sealing portion 4 of the preceding continuous packaging bag 1 and a front end sealing portion 5 of the succeeding continuous packaging bag 2. In a state of being overlapped by a required overlap amount, two pairs of clamp means 6 for sandwiching both parts 4 and 5 are disposed at a predetermined interval in the forward and backward directions, and both clamp means 6 are arranged. between, in this example, it is plugged into each of the seal portions 4, 5 of the above-rear sealing portion 4 while melting them both,
5 is provided with a heating pin 7 penetrating therethrough.

Here, the two pairs of clamping means 6 are:
For example, as shown in the figure, the respective fixed side members 6a connected to each other, and the respective fixed side members 6a are located opposite to each other, and are each independently operated or operated to be moved up and down by a common elevating drive means. And the movable side member 6b. Note that a cylinder or other known reciprocating means can be used as the lifting / lowering drive means for the movable member 6b, and the same applies to the forward / backward drive means for the heating pin 7.

By the way, since the heating pin 7 is stabbed in the heated state while melting the respective sealing portions 4 and 5, it is not always necessary to make the tip portion of the heating pin 7 tapered. Absent.

According to the device configured as described above, the respective movable portions 6b are connected to each other while the respective seal portions 4 and 5 are superimposed on the fixed side members of the respective clamp means 6. , Preferably by lowering them synchronously with one another, and then often by simultaneously lowering a plurality of heating pins 7, also penetrating them under melting of the two sealing parts 4, 5. The sealing portions 4 and 5 can be interconnected with a required strength, in other words, a strength that does not hinder the feeding and other handling of the subsequent continuous packaging bag 2.

That is, the interconnection here is made by melting the penetration of the heating pins 7 into the respective sealing portions 4 and 5, as described above, is located on both the front and back surfaces of the packaging bags 1a and 2a, and is often biaxial The molten portions of the sealant resins 1c and 2c directly or indirectly laminated on the stretched base films 1b and 2b are carried between the base films of the respective seal portions 4 and 5 while being adhered to the heating pins 7. It penetrates between the base films around the through holes of the pins 7, where it acts as an adhesive layer between the base films, one of the respective sealing parts 4, 5 being in its softened state the pins 7
In addition, being "entrained", this also flashes into the other melt-softened sealing portion to provide a mechanical bond, and furthermore, the base film itself is directly around the heating pin 7 Is performed on the basis of each of the welding.

Here, the connection strength of the two seal portions 4 and 5 depends on the number of the heating pins 7 arranged in a linear or staggered manner in a direction perpendicular to the plane of FIG. Can be changed as appropriate by selecting the diameter, cross-sectional contour shape, and the like. Here, the edge contour shape of each of the seal portions 4 and 5 can be appropriately selected as required, in addition to a linear shape or a zigzag shape as shown in a plan view in FIG. .

By the way, the connection strength of each of the sealing portions 4 and 5 is such that there is no problem in feeding out the subsequent connection packaging bag 2 and the like, while the connection is performed in the above-described manner. The connection can be easily and reliably dissociated by the action of a collision impact on the connection portion that is equal to or greater than a predetermined value, and the dissociation is performed as if the other seal portion 5 had just been separated from one seal portion 4. Therefore, no adhering matter that impairs the appearance of the packaging bag remains in any of the seal portions.

FIG. 3 is a schematic side view showing an application example of the apparatus according to the present invention. In FIG. 1 shows a continuous packaging bag to be used.

Here, the percussion cutting device 11 preferably has a feeding side conveyor 14 for holding and feeding a continuous packaging bag 12 placed in a cardboard box 13, and a cut packaging bag 12a also holding the same. , A carry-out conveyor 15 running at a speed slightly faster than the pay-out conveyor 14, and a translating or rotating motion that is arranged between the two conveyors and detects the passage of a packaging bag according to the required number of continuous packages. And a rod-shaped member 16 for applying a cutting impact to a perforated wound portion of the continuous packaging bag 12 or a portion in the vicinity thereof,
The cut packaging bag 12 is transferred from the conveyor 15 to a loading device 17 for an automatic food packaging apparatus, for example.

By the way, at the rear end sealing portion of the continuous packaging bag 12 currently being cut, the front end sealing portion of the preceding continuous packaging bag 1 stored in another cardboard box 13 is, for example, a portable type invention device. Are connected in advance as described above. Accordingly, the cutting device 11 is operated by horizontally moving the cardboard box 13 containing the preceding continuous packaging bag 1 to a position below the impact cutting device 11 in synchronization with the end of cutting of the continuous packaging bag 12. The cutting of the preceding continuous packaging bag 1 can be started without stopping.

Further, as shown in FIG.
On the fixed side member, the front end sealing portion 4 of the succeeding continuous packaging bag 2 is superimposed on the rear end sealing portion 4 of the preceding continuous packaging bag 1, where the two sealing portions 4, 4 formed by the respective movable side members 6b. By successively carrying out the pinching of 5 and the insertion of the heating pin 7 into both seal portions 4 and 5, it is possible to connect the subsequent continuous packaging bag 2 to the continuous packaging bag 1 prior to the end of cutting the continuous packaging bag 1. By repeating these connecting operations, the cutting device 11 can be operated continuously until the cutting of the predetermined amount of the connected packaging bags is completed.

Although the present invention has been described with reference to the illustrated example, the fixed side member 6a of the apparatus 3 may be a movable member which is also reciprocated differentially by a cylinder or the like.
