Description

  The present invention relates to a boxing device that folds a continuous packing bag (also referred to as a “continuous pouch”) in a state in which small bags filled with powder or liquid such as soup or condiment are connected and packed in a container (such as a case). The present invention also relates to a folding box filling device with a measurement function for determining whether or not there is an abnormality in filling a small bag.

  Many products lined up in stores contain packaging bags, and generally food products enclose small bags (pouches, packagings) of seasonings and the like in the packaging bags.

  In such a sachet, powder and liquid packages such as soup and condiments are filled and sealed by a filling device.

  In general, the sachets (pouches, packages) are distributed in a continuous package (also referred to as a “continuous package”) in which the sachets are connected at a predetermined short interval until they are enclosed in the packaging bag. Handling is done.

  Specifically, in the continuous package, a horizontal seal portion along the width direction is formed by welding on a cylindrical resin sheet at an appropriate interval, and the space between the horizontal seal portions serves as a storage portion. In this case, the packaging material is filled in a state in which one side seal portion (one in the continuous package body length direction) is formed in the housing portion, and then the other side seal portion is formed by welding, and the packaging material is made of resin. Enclose in a sheet. In this way, a gap is formed between the lateral seal portions.

  In the state of the continuous package, it is transported to the small bag loading place, and the small bags individually separated from the continuous package are loaded into the packaging bag.

  The continuous package after the objects to be packaged are filled and sealed by the filling device is continuously supplied to the boxing device in a continuous form, and the boxing device is folded into a predetermined case in a storage case (container). ).

  The applicant sets the number of sachets to be put in the storage case in advance when continuously packing the continuous package from the filling machine, and automatically packs the predetermined number of continuous packages. ing.

  Also, an empty bag detector that detects the empty bags (those with little or no filling amount) by detecting the thickness by sandwiching the continuous package with rolls, or detecting the contents with a transmission type optical sensor. I'm thinking about what to provide.

Regarding the packaging of continuous packages, in Japanese Patent Laid-Open No. 6-298203 (Patent Document 1), the housing case is placed in a direction perpendicular to the folding direction of the continuous package so that the continuous package is not biased and housed in the case. It proposes technology to move.
JP-A-6-298203

  However, in the conventional boxing device, even if setting and confirmation of the number of boxing can be done to pack the set number of boxes, it is not possible to check the amount of continuous packaging bags packed in a box, and if the filling machine malfunctions, There is a problem that the filling amount of the sachet is insufficient or not continuously.

  Conventionally, as a countermeasure against such a shortage, the weight of the boxed product is checked at another place after the boxing operation, which has been an obstacle to improving the work efficiency.

  In addition, when detecting a defective product of a small pouch (pouch) in the middle of packing a folding box, it is conceivable to use the thickness of the “pouch”, but when detecting a defective product (empty bag) using this thickness, Depending on the filled contents (things that are not easily deformed, those that have a large amount of air filling, etc.), there is a problem that it is difficult to detect a small amount.

  Moreover, the shortage of the filling amount of contents tends to occur continuously, and if it is not detected quickly, the frequency of mixing in defective products increases. However, no technology that can cope with this has been proposed.

  The present invention has been made in order to solve the above-described problems, and it is possible to increase the working efficiency by simultaneously performing the boxing operation and the inspection operation of the continuous packaging body in which the sachets are continuously arranged, and the filling machine that is continuously generated. It is intended to provide a folding boxing device with a quantity measurement function that can check defects (insufficient filling amount) in the middle of boxing so that it can immediately respond to defects and can reliably carry out boxing without contamination of defective products. is there.

  The present invention relates to a folding box packing apparatus with a quantity measurement function.

  The present invention relates to a boxing device that folds a plurality of continuous sachets filled with packages to be packaged and accommodates them in a box-shaped container, and is based on the target number of sachets in the continuous package accommodated in the container. Based on the weight setting means for setting the target weight, the weight detection means for detecting the weight of the continuous package housed in the container, the weight detected by the weight detection means and the set target weight A folding box filling device with a quantity measuring function, comprising: a pouch abnormality judging means for judging whether or not there is a pouch filling abnormality in the continuous package housed therein.

  In the present invention, the weight setting means is capable of setting a midway target weight based on the intermediate target number of sachets before reaching the final target number of sachets of the continuous package finally stored in the container, When the target number is accommodated, the weight detection means detects the weight of the continuous package, and at the same time, the sachet abnormality determination means determines the weight of the continuous package detected by the weight detection means and the set intermediate target. Based on the weight, it is preferable to determine whether or not there is an abnormal filling of the sachets in the continuous package housed in the container.

  Further, in the present invention, a sachet counting means for counting the number of sachets of the continuous package accommodated in the container, and a step of determining whether or not the number of sachets counted by the sachet counting means has reached a target number during the sachet. When the number of sachets is determined to be the target number during the sachet by the intermediate number determination means, the storage of the continuous package in the container is stopped, and the weight in the storage stop state is provided. It is preferable to detect the weight of the continuous package accommodated in the container by the detecting means and to determine the abnormal filling of the small bags by the small bag abnormality determining means.

  In the present invention, it is preferable that the weight detection means is provided with a weight sensor for detecting the weight of the continuous package together with the container on the mounting table on which the box-shaped container is mounted.

  In the present invention, the weight setting means sets the ideal value of the target weight from the ideal value per sachet and the target number of sachets, and the minimum allowable value and the maximum allowable value with respect to the target weight ideal value, Is preferably set.

  According to the folding box packing apparatus with the quantity measuring function according to claims 1 to 5 of the present invention, the sachet abnormality determining means accommodates in the container based on the weight detected by the weight detecting means and the set target weight. Since it is judged whether or not there is an abnormal filling of the small bag in the continuous package, it is possible to check the weight at the same time as the boxing of the continuous package is completed, and to detect an abnormal filling of the child bag (quantity abnormality). Improvements can be made.

  In addition, the contents that are filled when using the “thickness of the sachet” to detect defective products in the sachet in the middle of folding box packing (things that are easily deformed or that are often filled with air, etc.) Some of them are difficult to detect when the amount is small. In the present invention, paying attention to the fact that even such a thing tends to occur underfilling easily, it is possible to reliably detect underfilling of the contents by weight detection, and the effect of preventing the introduction of defective products is improved. .

  The invention described in each claim has the following effects in addition to the above effects.

  According to the second aspect of the present invention, the weight setting means makes it possible to set the midway target weight based on the intermediate target number of sachets before reaching the final target number of sachets of the continuous package finally contained in the container. The weight detection means detects the weight of the continuous packaging body when the target number of sachets is accommodated in the container, and the sachet abnormality judgment means also detects the weight of the continuous packaging body detected by the weight detection means. Since it is determined whether or not there is an abnormal filling of the sachet in the continuous package housed in the container based on the set intermediate target weight, the weight check is performed a plurality of times until the packaging of the continuous package is completed. This can be confirmed when a filling defect occurs in the machine, and the line can be inspected, leading to the reduction of defective products.

  According to invention of Claim 3, when it determines with the number of said sachets becoming the target number in the middle of a sachet by the way number judgment means, the accommodation to the container of a continuous package is stopped, and the accommodation stop state The weight detection means detects the weight of the continuous package housed in the container and the sachet abnormality judgment means judges the filling error of the sachet, so the weight detection and the sachet abnormality are judged without changing the weight. Detection and determination can be performed with high accuracy.

  According to the invention described in claim 4, since the weight detecting means is provided with a weight sensor for detecting the weight of the continuous package together with the container on the mounting table for mounting the box-shaped container. This eliminates the need to detect the weight of the continuous package separately from the container, and improves work efficiency.

  According to the invention described in claim 5, the weight setting means sets the ideal value of the target weight from the ideal value per sachet and the target number of sachets, and the minimum allowable value for the ideal target weight value. Since the maximum permissible value is set, the permissible range for the ideal value of the target weight can be set corresponding to the variation in the filling amount (tolerance of the filling amount) for each bag. That is, if the target weight is set to an ideal value, even if the filling amount of the sachet is within the tolerance range, the problem of detecting an abnormality can be solved, and the working efficiency can be improved.

  The container 12 is manually or automatically replaced from the upper surface of the cart means 26 when a predetermined amount of the continuous package 10 product is stored in the container 12. In the case of automatic replacement, a supply device is provided in the lateral direction of the carriage means 26 to automatically supply the container 12 onto the carriage means.

  Further, the cart means 26 for placing the container 12 is operated by a motor in the front-rear direction, and moves back and forth in synchronism with the supply of the product so that the continuous package 10 is uniformly aligned and accommodated.

  The continuous package 10 is tared (S3). That is, the weight of the container 12 is added to the weight detection sensor unit 16a (weight checker). In order to make the weight display correspond to only the product in the container 12, the weight of the empty box is measured here, and a value obtained by subtracting the weight is output as a subsequent weight measurement value.

  The continuous package 10 is initially boxed. That is, it introduce | transduces into the container 12 of the continuous packaging body 10 of predetermined amount small sachet (S4). In order to perform subsequent boxing and alignment, a part of the product is placed in the container 12 so that the top position and the first row of the product are arranged, or the tape is attached to the container. There are also cases where an operator (operator) intervenes for work such as taking out the machine.

  An arbitrary number of sachets is set for the continuous package 10 of products in the container 12, and the weight is measured for each number of sachets (weight measurement point). Based on the number of detected pouches of the counter, the container 12 is packed up to the set number (S5).

Up to 10 weight measurement points can be set. In addition, how many small bags are packed in one box of the container 12 can be set in advance.
FIG. 9 and FIG. 10 show setting screen examples.

  For the set number, a weight measurement point (a small pouch value: a counter value) is set in the “point” column. In the figure, points are set from “1 <2 <3 <4 <5 <6 <7 <8 <9 <FINISH”, and the points correspond to the number of pouches. In the example of FIG. 9, the weight was measured at 400 bags, 800 bags, 1200 bags, and 1600 bags. “FINISH” indicates completion of packing, and the number of bags is set separately. In the “min” and “max” columns, the upper limit and the lower limit of the weight at each point are set.

  Next, it is determined whether or not the packaging is completed (S6). Based on the counted number of small bags, it is determined whether or not the set number of small bags to be packed in the container 12 is packed in the box. When the set number is counted, the packaging is completed.

On the other hand, if the boxing is not completed, it is the time when the pouch is boxed up to each weight measurement “point”.
That is, as a result of the determination, if boxing is not completed, specifically, it is a point on the way that is not “FINISH” (S6: NO).

  In that case, in the boxing device, the product introduction into the container 12 is temporarily stopped (S7), and the detection plate 16b of the weight detection means 16 on which the container 12 is placed is stopped. In this state, the weight of the continuous packaging body 10 in the container 12 is measured, and the determination result of whether or not the weight value is within the upper limit value and the lower limit value together with the measured weight value is appropriate (“GO” And “NG” is displayed as “NG”) (S8).

  That is, when the detection plate 16b is stationary with respect to the detection sensor unit 16a, the weight can be accurately detected. The stationary time is about 1 to 3 seconds. This still time can also be set by a “set” button as shown in FIG.

Further, the weight detection sensor unit 16a on the carriage 26 is instructed to measure the weight of the container 12 containing the continuous package 10, and the weight measurement result and determination result ("GO" / "NG") are set as data. And displayed on the data display unit 14a. An example of the display screen is shown in FIG.
After the weight detection process in S8, the process returns to S5 and the boxing process is repeated.

  On the other hand, if boxing is completed as a result of the above determination, specifically, the point is “FINISH” (S6: YES).

  In that case, in the boxing device, the introduction of the product into the container 12 is suspended (S9), and the detection plate 16b of the weight detection means 16 on which the container 12 is placed is stopped. In this state, the weight of the continuous package 10 in the container 12 is measured and displayed (S10).

That is, in this case as well as S7 and S8, the detection plate 16b is stationary with respect to the detection sensor unit 16a, so that the weight can be accurately detected. The stationary time is about 1 to 3 seconds. This still time can also be set by a “set” button as shown in FIG.
In addition, the weight detection sensor unit 16a on the carriage 26 is instructed to measure the weight of the container 12 that houses the continuous package 10, and the weight measurement result is displayed. An example of the display screen is shown in FIG.

  As shown in FIG. 16, the weight measurement result is displayed on the data display unit 14 a of the weight setting unit 14 in correspondence with each point and “FINISH”. As each point is measured, a new measurement value and determination result are added.

When the determination result is “GO”, the next boxing operation is performed toward the next point as shown in the flowchart of FIG.
On the other hand, when the judgment result is “NG”, two options are prepared as settings: the next boxing operation is performed toward the next point according to the flowchart of FIG. 15 and the boxing is interrupted here. is doing.

  According to the folding box packing apparatus with a quantity measurement function according to the embodiment, the continuous packaging accommodated in the container 12 by the pouch abnormality determination means 18 based on the weight detected by the weight detection means 16 and the set target weight. Since it is determined whether or not there is an abnormality in filling the small bag in the body 10, it is possible to check the weight at the same time when the boxing of the continuous packaging body 10 is finished, and to detect an abnormality in filling the child bag (quantity abnormality), thereby improving work efficiency. Can be planned.

  In addition, the contents that are filled when using the “thickness of the sachet” to detect defective products in the sachet in the middle of folding box packing (things that are easily deformed or that are often filled with air, etc.) Some of them are difficult to detect when the amount is small. In this embodiment, paying attention to the fact that even such items tend to be continuously filled with insufficient contents, it is possible to reliably detect insufficient filling of contents by detecting weight, and to prevent the introduction of defective products. improves.
