BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a product in which one bag or a plurality of required bags are cut and separated from a continuous packaging bag filled with seasoning, soup and the like, and the packaging bag is used as a seasoning. The present invention relates to a method for connecting continuous packaging bags and a device used therefor, which is suitable for automatic repackaging together, and makes it possible to connect the continuous packaging bags to each other very simply and quickly and at the connection position of the continuous packaging bags. In addition, the re-separation of the tape is always assured, and in addition, the possibility that tie tape or other foreign matter may get mixed into the product packaging bag is completely eliminated.

2. Description of the Related Art Repackaging a packaging bag filled with seasonings and other products together with a product using the packaging bag. For example, a food maker often packages a plurality of seasoning packaging bags together with the product depending on the quantity of the product. is there. In such cases,
In general, food manufacturers continuously produce as many seasoning packaging bags as the number corresponding to the amount of their own products packaged in one bag, and produce seasoning packaging bags such as double packaging and triple packaging. It is purchased from food manufacturers, seasoning filling processors, and others, or is produced in-house.

However, this means that the food manufacturer needs to prepare in advance a seasoning packaging bag of a type corresponding to the specifications of its own product quantity and having a different number of consecutive packages. There was a problem that bag inventory management was troublesome. In addition, in order to adapt seasoning packaging bags such as double packaging and triple packaging to automatic packaging of own products, in many cases, seasoning packaging bags for each continuous packaging packed in a cardboard box are delivered. However, there is also a problem in man-hours that it is necessary to manually take out the cardboard box from the cardboard box and set the packaging bags in the automatic machine in a state where they are aligned.

[0004]

[Background Art] Therefore, in order to solve the above-mentioned problems of the prior art, the applicant first cuts a long continuous packaging bag from an arbitrary continuous packaging bag as Japanese Patent Application No. 4-302037. A device that can be separated was proposed. This device is provided with a feeding means for a continuous packaging bag having perforations or surface flaws in a unit of one packaging bag, and a counting means for counting the number of packaging bags passing through the feeding means. Then, a rod-shaped member is provided which makes a translational or rotational movement based on the signal from the counting means and collides with the continuous packaging bag. According to this apparatus, while feeding out the continuous packaging bag 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 the rod-shaped member is moved after detecting the passage of the required number of packaging bags. By operating and colliding it with the perforation-like scratched position of the continuous packaging bag or a position in the vicinity thereof, it is possible to cut and separate the required number of continuous packaging bags from the continuous packaging bag by the impact of collision. Becomes

Therefore, according to such an apparatus, the food maker only needs to prepare one kind of continuous packaging bag such as a seasoning having perforation-like scratches for each packaging bag, and the continuous packaging as required. It is possible to appropriately cut and separate several packaging bags from the continuous packaging bag. Therefore, a food maker has an advantage that, for example, inventory control of seasoning packaging bags is extremely easy, and the number of man-hours for handling seasoning packaging bags can be significantly reduced during automatic packaging of products.

[0006]

By the way, in order to sufficiently functionally perform the above-mentioned cutting and separating of the required number of continuous packaging bags from the continuous packaging bag, they are usually delivered in a corrugated cardboard box. By pre-connecting the rear end seal part of one continuous packaging bag and the leading end seal part of another continuous packaging bag, it is possible to stop it without stopping the cutting device each time the continuous packaging bag is switched. Where continuous operation is required, if the connection is performed with an adhesive tape that has been widely and conventionally used for connecting packaging films, the number of work steps for connection increases. With
There is a problem that the use of adhesive tape is indispensable.
Further, when it becomes necessary to cut and separate the packaging bag at the connecting position, there is a problem that it is practically impossible to cut the packaging bag by the blow cutting device as described above. , When it is not necessary to cut at the connecting position, the packaging bag for seasonings including adhesive tape will be repackaged with the product, and the value and appearance of the product will be reduced. was there.

[0007] Here, in order to ensure the cutting and separation of the packaging bag, when the cutting is performed by a cutting device using a shearing blade, it is possible to cut from the connecting portion by the adhesive tape. , In this case also, it is not possible to prevent the packaging bag with the adhesive tape cut by the shearing blade from being repackaged with the product, and
There was a high possibility that cutting wastes of at least one of the leading end sealing portion and the trailing end sealing portion of the continuous packaging bag that were abutted or overlapped with each other would be mixed into the repackaging bag.

The present invention has been made as a result of studying as a subject to solve such a problem resulting from 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 a required strength without using any other special connecting material, and the connection can be surely released by hitting with a hitting cutting device. In addition, even if the packaging bag such as seasonings is repackaged together with the product without disconnecting the connection, there is no possibility of deteriorating the value, appearance, etc. of the product. To provide.

[0009]

SUMMARY OF THE INVENTION A method for connecting continuous packaging bags according to the present invention includes a rear end seal portion of a continuous packaging bag in which a large number of packaging bags are continuous through perforations or surface scratches. Similarly, when connecting the leading end seal portion of another continuous packaging bag, after the leading end seal portion and the trailing end seal portion are overlapped and sandwiched, at least the respective leading and trailing end seal portions are sandwiched by the sandwiching portion. The heated pin is penetrated to one side. The device of the present invention is
A pair of clamp means is provided for sandwiching the leading end seal portion and the trailing end seal portion in their overlapping posture, and at least one of the leading and trailing end seal portions is inserted between the respective clamping means. And a heating pin passing therethrough is disposed.

[0010]

In this continuous packaging bag connecting method, when the heated pins are pierced through both the seal portions at the front and rear ends, for example, when the heated pins are penetrated, , The melted part of the sealant resin laminated on the base films located on both the front and back sides of the packaging bag adheres to the pins and is carried between the base films of the vertically adjacent seal parts, and the pins penetrate. To intervene between the base films around the holes to function as an adhesive layer between the base films, and secondly, one of the seal parts adjacent to each other,
Being "accompanied" by the pin in a softened state, which also enters a flash into the other melt-softened seal portion to provide a mechanical bond between the seal portions; and
Is based on the fact that the base films themselves of the upper and lower sealing parts are directly welded around the pins, etc., and the respective sealing parts at the front and rear ends are not used for feeding out continuous packaging bags or for other handling. They will be interconnected with the required strength without any hindrance.

Here, the connecting strength between the front and rear end seal portions is appropriately increased or decreased by selecting the number of pins penetrating both seal portions, the diameter of each pin, the cross-sectional contour shape of the pins, and the like. Can be made.

By the way, since the two continuous wrapping bags thus connected are connected with a relatively small joint strength that does not hinder the handling of the continuous wrapping bag,
When the connecting portion of both of them corresponds to a predetermined cutting and separating position, the connecting portion can be easily and surely broken and disengaged by colliding the rod-shaped member of the percussion cutting device with the connecting portion. Moreover, the connecting tape and other foreign matter do not remain on any of the separated sides.

On the other hand, since the connecting portion of the continuous packaging bag exists at a position where shear separation is unnecessary, the continuous packaging bag is repackaged with the product in a state where the connection is not disengaged. However, even if there is,
Since the heat-sealed parts at the rear end are simply superposed and joined, and it is almost impossible to visually recognize their existence from the outside, the value of the product, the appearance, etc. are impaired by the connecting part. That's not it. In addition, in this method, when the heating pin is passed through only one of the front and rear superposed seal parts, the connection of both seal parts is mainly made by the base films of both parts being directly connected to each other. Adhesively, and secondarily, the sealant resin of one sealing portion functions as an adhesive between the base films, again in the same manner as described above. Can bring about the action of.

Thus, according to this method, in the state in which the respective seal portions of the front and rear ends are overlapped and sandwiched,
By simply inserting a heated pin into the sealed portion, the two continuous packaging bags can be connected simply and quickly with the required strength without using any special connecting material. Moreover, this connection can be easily and reliably disengaged as required by the percussion-shaped scratch forming portion by the striking by the percussion cutting device. Then, as a result of reliable cutting and separation by the percussion cutting device, it is possible to completely eliminate the possibility of generation of sealing part cutting chips as in the case of using the shear blade cutting device.

Further, since the connection here is made only by superposing and joining the respective seal portions,
Not only when the seasoning, etc., to be packaged in the continuous packaging bag is repackaged in the undisconnected state, but also when it is repackaged with the product in the connected state, There is no loss of appearance.

In carrying out the above method,
In the case of using the invention device composed of a pair of two clamping means and a heating pin which is disposed between these two clamping means and which is inserted into at least one of the respective sealing portions at the front and rear ends, low cost is used. With a simple device, the front and rear ends of the continuous packaging bag can be reliably interconnected as intended.

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 invention device, in which 1 indicates a preceding continuous packaging bag and 2 indicates a subsequent continuous packaging bag that is unrolled thereafter.

The invention device 3, which can be either a portable type or a stationary type, has a trailing end seal portion 4 of the preceding continuous packaging bag 1 and a leading end seal portion 5 of the following continuous packaging bag 2. A pair of two clamping means 6 for sandwiching the two portions 4 and 5 in a state of being overlapped with each other with a required overlap amount are arranged at predetermined intervals in the forward and backward directions, and both clamping means are provided. In this example, a heating pin 7 that is inserted between the seal portions 4 and 5 at the front and rear ends and penetrates both of them is provided between 6 and 6.

Here, a pair of two clamp means 6
For example, as shown in the drawing, each of the fixed side members 6a connected to each other and the fixed side members 6a are located so as to face each other, and are lifted and lowered by independent or common lifting drive means. And each movable side member 6b. A known reciprocating means such as a cylinder can be used as the elevating and lowering driving means for the movable side member 6b, and this also applies to the advancing and retracting driving means for the heating pin 7.

By the way, since the heating pin 7 is stabbed into the heating pins 7 by melting the respective sealing parts 4 and 5 in its heated state, it is not always necessary to make the tip part thereof into a tapered shape. Absent.

According to the apparatus constructed as described above, the movable parts 6b of the respective clamp portions 6 are stacked on each other on the fixed side members of the respective clamp means 6, and the movable side members 6b of the respective clamp parts 6 are overlapped with each other. Clamping, preferably by actuating downwards in synchronization with each other, and then often by simultaneously lowering a plurality of heating pins 7 which also penetrate them under the melting of both sealing parts 4, 5. The seal portions 4 and 5 are interconnected with a required strength, in other words, with a strength that does not hinder the subsequent feeding of the continuous packaging bag 2 and other handling.

That is, the interconnection here is, as described above, located on both front and back surfaces of the packaging bags 1a and 2a by the melt penetration of the heating pin 7 into the respective seal portions 4 and 5, most of which are biaxial. The melted portion of the sealant resin 1c, 2c laminated directly or indirectly on the stretched base films 1b, 2b is carried between the base films of the respective seal portions 4, 5 while being attached to the heating pin 7. Entering between the base films around the through-holes of the pins 7, there acting as an adhesive layer between the base films, one of the respective sealing parts 4, 5 being in its softened state the pins 7
"Bringing" into the other sealing portion, which is also melt-softened, into a flash to provide a mechanical bond, and further, the base film itself is directly around the heating pin 7. The welding is performed on the basis of the occurrence of at least one phenomenon.

Here, the connecting strength of both the seal portions 4 and 5 is the number of heating pins 7 arranged in a straight line or zigzag shape in the direction orthogonal to the paper surface of FIG. The diameter and the cross-sectional contour shape can be selected as appropriate. Further, here, the edge contour shapes of the respective seal portions 4 and 5 may be a straight line shape, a zigzag shape or the like as shown in the plan view of FIG. 2, or may be appropriately selected as required. .

By the way, the connection strength of the respective seal portions 4 and 5 does not hinder the subsequent feeding of the connection packaging bag 2 and the like, while the connection is performed in the manner described above. The connection can be easily and reliably disengaged by the action of a collision impact of a predetermined value or more on the connecting part, and the disengagement is as if the other seal part 5 was just separated from the one seal part 4. Since it is carried out in the above, no sticking matter that would impair the appearance of the packaging bag remains on any of the sealing portions.

FIG. 3 is a schematic side view showing an application example of the device of the invention. In FIG. 3, 11 is an impact cutting device, and 12 is the impact cutting device 11 for cutting into a required number of continuous packaging bags. 3 shows a continuous packaging bag.

Here, the percussion cutting device 11 is preferably, for example, in a state where the continuous packaging bag 12 stored in the corrugated cardboard box 13 is sandwiched and fed out, and the cut packaging bag 12a is also sandwiched, as well. The conveyor 15 that moves at a speed slightly higher than that of the conveyor 14 and the conveyor 15 that is disposed between both conveyors, and detects the passage of the packaging bag according to the required number of continuous packages, and translates or rotates. And a rod-shaped member 16 for applying a cutting impact to the perforated portion of the continuous packaging bag 12 or a portion in the vicinity thereof,
The cut packaging bag 12 is delivered from the conveyor 15 on the conveying side to, for example, an inserter 17 for an automatic food packaging apparatus.

By the way, at the rear end seal portion of the continuous packaging bag 12 currently being cut, the leading end seal portion of the preceding continuous packaging bag 1 housed in another cardboard box 13 is, for example, a portable type invention device. Under the action of, the connection is made in advance as described above. Therefore, the cutting device 11 is operated by horizontally moving the corrugated cardboard box 13 containing the preceding continuous packaging bag 1 to a position below the percussion cutting device 11 at the same timing as the cutting of the continuous packaging bag 12 is completed. The cutting for the preceding continuous packaging bag 1 can be started without stopping.

Further, as shown in the figure, the device 3
On the fixed side member, the leading end seal portion 5 of the succeeding continuous packaging bag 2 is superposed on the trailing end seal portion 4 of the preceding continuous packaging bag 1, and both the sealing portions 4, 4 by the movable side members 6b are superposed there. By sequentially sandwiching 5 and inserting the heating pin 7 into both the seal portions 4 and 5, prior to the completion of cutting the continuous packaging bag 1, the subsequent continuous packaging bag 2 can be connected thereto. By repeating these connecting operations, the cutting device 11 can be continuously operated until the cutting of the predetermined amount of the connecting packaging bag is completed.

Although the present invention has been described above based on the illustrated example, the fixed side member 6a of the device 3 may be a movable member which is also reciprocally differential by a cylinder or the like.

Further, in using the device 3 as described above, the heating pin 7 is arranged on the upper side of the seal portion 5 in the drawing.
It is also possible to pierce only the base film 1 which is in contact with each other, mainly of the both sealing parts 4 and 5.
The continuous packaging bags 1 and 2 can be connected based on the direct welding of b and 2b. In this case, the heating pin 7
It is also possible for the tip of the tongue to penetrate somewhat into the sealing part 4 located below, whereby a similar connection can also be realized.

By the way, in such a usage state of the device 3, the space between both fixed side members shown in FIG. 1 is not necessary, so that the space can be partially or completely removed. If it is completely removed, it is possible to more sufficiently prevent the bending of the seal portions 4 and 5 when the heating pin 7 is inserted, and to make the insertion depth of the heating pin 7 highly accurate. It becomes possible to control.
