Description

The present invention relates to an enclosing device for enclosing contents in a bag, and a method for manufacturing an enclosed product in which contents are enclosed in a bag.

Conventionally, when using a bag in which release tape is attached to the adhesive part provided on the flap or the bag body (adhesive bag with release tape), the first step is to seal the contents inside the bag. Insert the contents into the bag body of the adhesive bag with release tape. After that, the release tape is peeled off to expose the adhesive portion, the flap is bent, and the flap is fixed to the bag body via the adhesive portion (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2004-59033

However, if the release tape cannot be properly removed from a glued bag with a release tape that has the contents inserted into the bag body, the folded flap cannot be properly fixed to the bag body, so such contents Bags with items inserted must be disposed of as defective items. However, in this case, not only the glued bag is wasted, but also the contents are inserted into the defective product, so if the bag is discarded as is, the contents will also be discarded. On the other hand, it is time-consuming to recover inserts from individual defective products.

The present invention has been made in view of such problems, and provides an enclosing device and an enclosing material that can reduce the loss and effort that may occur when the release tape cannot be properly peeled off from the adhesive bag with the release tape. The purpose is to provide a manufacturing method for.

(1) One aspect of the present invention for solving the above problems is an enclosing device for enclosing contents in a bag, which peels off the release tape affixed to the adhesive part of the adhesive bag with release tape. a peeling part, a peeling check part for detecting whether or not the peeling tape has been peeled off from the adhesive bag with the peeling tape, and an exposed adhesive inside the adhesive bag where the peeling tape has been peeled off and the adhesive part has been exposed; an insertion section into which the contents are inserted; and an insertion prevention section which prevents the contents from being inserted into the adhesive bag with release tape from which the release tape has been determined to be unable to be removed. and an enclosing part for fixing the flap of the glued bag with exposed glue into which the contents have been inserted in the insertion part to the bag main body part via the glue part.

In the above-mentioned enclosing device, before inserting the contents into the adhesive bag, the peeling tape attached to the adhesive part is peeled off by the peeling part. After that, the peeling check unit detects whether the peeling tape has been peeled off or not, and if the peeling tape has been successfully peeled off and the adhesive is exposed, the contents are inserted into the bag using the insertion unit. do. Then, the flap is fixed to the bag main body part through the adhesive part at the enclosing part. Thus, by using this enclosing device, an enclosing product in which the contents are enclosed in a bag can be obtained.

On the other hand, if the release section cannot peel off the release tape properly, that is, if the release check section determines that the release tape could not be peeled off from the bag, it is determined that the release tape could not be peeled off. The insertion prevention portion prevents the contents from being inserted into the glued bag with release tape (hereinafter also referred to as defective bag) at the insertion portion. Therefore, the contents are not discarded together with the defective bag, and losses can be reduced. Further, as mentioned above, there is no need to collect the contents from the defective product, and the trouble of recovering the contents can also be eliminated.

The "glued bag with release tape" used in the above-mentioned enclosing device and the manufacturing method described later can be used for various types of envelopes (for example, glued paper envelopes, glued film envelopes, glued paper envelopes, glued film envelopes, These include cushioned envelopes with adhesive, aluminum vapor-deposited film envelopes with adhesive), and bags (made of paper, resin film, etc.) for enclosing various items such as food and clothing.
In addition, there are so-called flap glue type bags that have a glue part formed on the flap, and so-called body glue type bags that have a glue part formed in the part of the bag body (body) that the flap covers when the flap is folded. Also included. In addition to bags without a gusset, bags with a gusset are also included.

The "glue part" provided on the adhesive bag with release tape includes the adhesive part formed by applying adhesive material directly to the material such as paper or resin film that makes up the bag and drying it, as well as the adhesive part that is formed by applying adhesive material directly to the material that makes up the bag, such as paper or resin film, and drying it. By pasting this, the parts of the double-sided tape other than the release tape (the first adhesive layer that adheres to the material forming the bag, and the second adhesive layer between the base material and the release tape) also fall under this category.
The release tape only needs to be formed to cover the entire glue part, and may be wider than the glue part, for example, in the bag depth direction perpendicular to the bag width direction, or it may be wider than the glue part in the plane dimension of the glue part. They may have the same dimensions.

The contents to be sealed in the bag using the above-mentioned sealing device and the manufacturing method described below may be anything that can be sealed in a glued bag, such as postcards, greeting cards, letters, books, CDs, miscellaneous goods, clothing, and food. Examples include products.

In the insertion prevention section, when a glued bag with release tape (defective bag) is found in which the release check section determines that the release tape could not be removed, the insertion section inserts the contents into the defective bag. to prevent This insertion prevention section includes a bag ejection mechanism that ejects defective bags to a predetermined ejection site. In addition, if a defective bag occurs, there is a processing section that manually discharges the defective bag, for example, a peeling section and a bag with exposed adhesive from the peeling section to the insertion section, and temporary processing of the entire enclosing device. An example is a processing unit that causes a stop or slowdown. Also included is a processing unit that performs notification processing such as displaying a monitor screen, lighting a notification lamp, and sounding a notification buzzer to notify the occurrence of a defective bag.

In addition, as the bag ejection mechanism, an appropriate mechanism can be adopted, taking into account the size, material, weight, and transportation method from the peeling section to the insertion section of the adhesive bag with release tape. At a predetermined location on the transport path toward the department, lift the defective bag using a suction cup or adhesive, suck the defective bag using a suction hose, or blow the defective bag away by blowing high-pressure air. One example is a mechanism that discharges defective bags from the conveyance path by moving them to a predetermined discharge site.

(2) Furthermore, in the enclosing device according to (1), in the glued bag with release tape and the glued bag with exposed glue, the glue portion is formed on the flap, and the insertion portion includes: an opening mechanism for opening the bag entrance of the bag body of the bag with exposed glue; a contents insertion mechanism for inserting the contents into the bag body through the opened bag entrance; The enclosing device preferably includes a contact prevention mechanism that prevents contact between the contents to be inserted and the adhesive portion formed on the flap.

In this enclosing device, the insertion section includes an opening mechanism, a content insertion mechanism, and a contact prevention mechanism. For this reason, even when using a glued bag with an adhesive part formed on the flap and the adhesive exposed from which the release tape has been peeled off, the contents can be inserted into the bag main body without causing the problem of sticking to the adhesive part. can do.

The "opening mechanism" is a mechanism for opening the bag entrance of the bag body, and an appropriate opening mechanism can be adopted depending on the material and size of the bag, the size and material of the contents to be inserted, etc. For example, in a case where the bag main body part has a first main body part and a second main body part which are made of paper, resin film, etc. and overlap each other in the bag thickness direction, the first bag entrance part near the bag entrance of the first main body part , a suction cup is attached to a second bag entrance portion near the bag entrance of the second main body portion. Another example is a mechanism that opens the bag entrance by moving the suction cups in the bag thickness direction to opposite sides (separated from each other).

The "contents insertion mechanism" is a mechanism that inserts the contents into the bag body through the bag entrance, and an appropriate contents insertion mechanism is adopted depending on the size and material of the contents, the material and size of the bag, etc. can. Note that the content insertion mechanism can be configured as a separate mechanism from the opening mechanism, but it also includes a case where the members that make up the opening mechanism also serve as the members that make up the content insertion mechanism. For example, a member that is inserted into a bag entrance to open the bag entrance may also be used as a guide member that guides the contents to be inserted into the bag main body.

The "contact prevention mechanism" is a mechanism that prevents the contents being inserted into the bag body from coming into contact with the exposed adhesive formed on the flap. An appropriate contact prevention mechanism can be adopted depending on the size and the size of the bag entrance to be opened. For example, prior to inserting the contents into the bag main body, there is a mechanism in which the exposed adhesive part is covered with a separator or a guide plate that guides the contents into the bag main body through the bag entrance, and a bag main body In contrast, the flap having the adhesive part is bent or warped in the direction opposite to the adhesive side when viewed in the thickness direction of the flap, and the adhesive part is removed from the intended content passage area where the contents to be inserted into the bag body are intended to pass. An example of this is a mechanism that keeps the two parts separated from each other. Furthermore, these can also be employed in combination.
In addition, as for the separator or guide plate that covers the glue part, it is preferable that at least the part of the surface on the glue part side near the glue part is made of a material that does not stick to the glue part or has been subjected to a surface treatment that does not stick to the glue part. .

(3) Another aspect of the present invention for solving the above problems is a method for manufacturing an enclosed product in which contents are enclosed in a bag, the peelable tape being attached to the glue part of a glued bag with a release tape. a peeling step of peeling off the tape; a peeling check step of detecting whether the release tape has been peeled off from the glue-attached bag with the release tape; and exposed glue where the release tape is peeled off and the glue portion is exposed. an insertion step of inserting the contents into the bag with the adhesive; a discharge step of ejecting the adhesive bag with the release tape from which it was determined that the release tape could not be removed before the insertion step; This method includes the step of fixing the inserted flap of the glued bag with exposed glue to the bag main body via the glue part.

In the above-mentioned method for producing an enclosure, the release tape affixed to the adhesive portion is peeled off in the peeling step before the insertion step of inserting the contents into the glued bag. After that, in the peeling check process, it is detected whether or not the release tape has been peeled off.If the peeling tape has been successfully peeled off and the adhesive is exposed, the contents of the bag are inserted into the bag in the insertion process. do. Then, in the enclosing step, the flap is fixed to the bag body via the adhesive. Thus, by this method for producing an enclosure, an enclosure in which the contents are enclosed in a bag is obtained.

On the other hand, if the release tape at the adhesive part cannot be peeled off properly in the peeling process, that is, if it is determined that the release tape could not be peeled off in the peeling check process, the discharge process will remove the tape before the insertion process. Eject the defective bag. Therefore, the contents are not discarded together with the defective bag, and losses can be reduced. Further, as mentioned above, there is no need to collect the contents from the defective product, and the trouble of recovering the contents can also be eliminated.

In the discharge process, if a glued bag with release tape (defective bag) whose release tape could not be peeled off occurs in the peel check process, this defective bag is discharged before the insertion process. That is, the contents are prevented from being inserted into the defective bag during the insertion process. This discharge process includes a method of discharging the defective bag to a predetermined discharge site using a bag discharge mechanism. Alternatively, defective bags may be manually discharged. In the case of manual discharge, in order to facilitate manual discharge, for example, a peeling unit that performs the peeling process and an enclosure device that transports the exposed adhesive bag from the peeling unit to the insertion unit that performs the insertion process and manufactures the enclosed items. It is also possible to include processing that causes the entire processing to temporarily stop or slow down. It is also possible to include processing for performing notification processing such as displaying a monitor screen to notify the occurrence of a defective bag, lighting a notification lamp, and sounding a notification buzzer.

(4) Furthermore, in the method for manufacturing an enclosure according to (3), in the adhesive bag with release tape and the adhesive bag with exposed adhesive, the adhesive part is formed on the flap, and the adhesive part is formed on the flap; The steps include: opening the bag entrance of the bag main body of the glue-exposed bag; and opening the bag entrance while preventing the contents from contacting the adhesive portion formed on the flap. The method for manufacturing an enclosure preferably includes a content insertion step of inserting the content into the bag main body through the bag body.

In this method of manufacturing an enclosed product, the insertion step includes an opening step and a contents insertion step of inserting the contents into the bag body through the opened bag entrance while preventing the contents from coming into contact with the adhesive part of the flap. have. Therefore, even if the flap has an adhesive part and the adhesive is exposed after the peeling tape has been peeled off, the contents will not stick to the adhesive part, and the contents can be transferred to the bag body. It can be inserted inside the body.

(Embodiment)
Hereinafter, an enclosing apparatus 100 according to an embodiment of the present invention and a method for manufacturing a packaged postcard (enclosed material) EC using the same will be explained with reference to FIGS. 1 to 12.
First, a pre-peel bag E in which the release tape SFT is peeled off and removed by the enclosing device 100 of this embodiment or the like will be described (see FIGS. 1(a) and 1(b)). The pre-peel bag E (the same applies to the uppermost pre-peel bag E1 described later) is a transparent bag made of a resin film, specifically biaxially oriented polypropylene (OPP), and has a rectangular shape in plan view. This pre-peeling bag E is made by folding a resin film at the bottom edge EBB and sealing it by melting at one side edge ES1 and the other side edge ES2, and the bag body part EB has a bag entrance EBO open. and a flap EF protruding from the bag body EB.

In this rectangular pre-peel bag E, the direction along the bottom edge EBB is the bag width direction BWH, the direction toward one side edge ES1 is one side BWH1, and the direction toward the other side edge ES2 is the other side BWH. The side is BWH2. Further, the direction connecting the bag entrance EBO and the bottom edge EBB is defined as the bag depth direction BDH. Furthermore, the direction in which the resin films are folded (vertical direction in FIG. 1(b)) is defined as the bag thickness direction BTH, and among these, the downward direction in FIG. 1(b) is one side BTH1, and the upward direction is the other side BTH2. shall be.

The bag main body part EB is composed of two resin films that are folded and overlapped in the bag thickness direction BTH. In the bag main body part EB, the part located on one side BTH1 (lower in FIG. 1(b)) and connected to the flap EF is called the first main body part EB1, and the part located on the other side BTH2 (upper in FIG. 1(b)) The portion to which this is done is referred to as a second main body portion EB2.

A glue portion EFG extending in the bag width direction BWH is formed on the flap EF, and a rectangular release tape SFT made of a resin film is adhered to cover the glue portion EFG. The pre-peeling bag E is a so-called flap glue type bag.
In the pre-peel bag E, the rectangular peel tape SFT extends in the longitudinal direction SLH (vertical direction in the figure) that coincides with the bag width direction BWH.
In addition, as the pre-peeling bag E, as shown by the broken line in FIG. 1, the flap EF is not provided with a glue part, and a glue part EBG extending in the bag width direction BWH is formed in the vicinity of the bag entrance EBO in the bag body part EB. However, a so-called body-glue type bag may be used, in which a release tape SBT is adhered to cover the bag.

In the peeling step S1 (see FIG. 6), which will be described later, the bag from which the peeling tape SFT of the pre-peeling bag E is peeled off by the peeling unit 110 of the enclosing device 100 is the glue-exposed bag Ege (FIG. 2(a), (see (b)). In this glue-exposed bag Ege, the glue portion EFG is exposed by removing the release tape SFT.

Furthermore, in an insertion step S4 (see FIG. 6) to be described later, a predetermined number of sheets (in this embodiment, five sheets) as contents are inserted into the bag main body part EB of this adhesive exposed bag Ege using the insertion section 140 of the enclosing device 100. The bag into which the stacked postcards CN are inserted is the inserted bag Ein (see FIGS. 3(a) and 3(b)).

Furthermore, in the later-described enclosing step S5, the enclosing unit 180 of the enclosing device 100 bends the flap EF of the inserted bag Ein, fixes the flap EF to the bag main body part EB via the glue part EFG, and secures the postcard (contents). The bag in which CN has been sealed is the sealed bag Een (see FIGS. 3(a) and 3(b)). Furthermore, the enclosed bag Een and the postcard CN enclosed in the enclosed bag Een form a packaged postcard EC (enclosed object).

As shown in FIG. 5, the enclosing device 100 of this embodiment generally includes a peeling section 110, a peeling check section 120, an ejection section (insertion prevention section) 130, an insertion section 140, and an enclosing section 180. .

The peeling unit 110 of this enclosing device 100 peels off and removes the peel tape SFT from the pre-peel bag E (see FIG. 1) to form an exposed adhesive bag Ege (see FIG. 2). The peeling check section 120 inspects the adhesive exposed bag Ege to detect whether the peeling tape SFT has been peeled off from the pre-peeling bag E. The discharge unit 130 discharges the pre-peel bag E (hereinafter referred to as a defective bag Eng) for which the peel check unit 120 determined that the release tape SFT could not be peeled off, and inserts a postcard into the defective bag Eng using the insertion unit 140. Prevent CN from being inserted. On the other hand, the glue-exposed bag Ege from which the release tape SFT has been peeled off and the glue portion EFG has been exposed passes through the discharge section 130. In the insertion section 140, the postcard CN is inserted into the adhesive exposed bag Ege to form an inserted bag Ein (see FIG. 3). The insertion section 140 includes an opening mechanism 150 that opens the bag entrance EBO of the bag body EB of the glue-exposed bag Ege, and a postcard insertion mechanism (contents insertion) that inserts the postcard CN into the bag body EB through the bag entrance EBO. mechanism) 160, and a contact prevention mechanism 170 that prevents contact between the inserted postcard CN and the adhesive portion EFG of the flap EF. Further, in the enclosing section 180, the flap EF of the inserted bag Ein is bent and the flap EF is fixed to the bag main body section EB via the glue section EFG, and the packaged postcard (with the postcard CN enclosed in the enclosed bag Een) ( Enclosure) Complete the EC.

The method for manufacturing a packaged postcard (enclosure) EC using the above-mentioned enclosing device 100 generally involves the following steps shown in FIG. That is, in the peeling step S1, the peeling tape SFT stuck to the adhesive part EFG of the pre-peeling bag E (see FIG. 1) is peeled off. That is, an exposed glue bag (see FIG. 2) is formed. In the peeling check step S2, it is detected whether the peeling tape SFT has been peeled off from the bag E before peeling. If No, that is, it is determined that it could not be peeled off, the process proceeds to discharge step S3. On the other hand, if Yes here, that is, if it can be peeled off, that is, if the adhesive exposed bag Ege can be formed, the process proceeds to insertion step S4.

In the discharge step S3, the pre-peel bag E from which it was determined that the release tape SFT could not be peeled off, that is, the defective bag Eng, is discharged before the insertion step S4 is performed.

On the other hand, in the insertion step S4, the postcard CN is inserted into the adhesive exposed bag Ege. That is, an inserted bag Ein (see FIG. 3) is formed. Note that this insertion step S4 includes an opening step S41 of opening the bag entrance EBO of the bag body portion EB of the adhesive exposed bag Ege, and an opening step S41 of opening the bag entrance EBO of the bag body portion EB of the adhesive exposed bag Ege, while preventing contact between the postcard CN and the adhesive portion EFG formed on the flap EF. It has a postcard insertion step S42 of inserting the postcard CN into the bag main body part EB through the bag entrance EBO. Next, in the enclosing step S5, the flap EF of the inserted bag Ein is fixed to the bag body part EB via the glue part EFG, and the production of the packaged postcard EC in which the postcard CN is enclosed in the enclosed bag Een is completed.

Next, the peeling section 110 of the enclosing device 100 according to this embodiment will be explained. The peeling unit 110 includes a pasting mechanism 20, a peeling mechanism 30, and an adhesive tape moving mechanism 40. First, the sticking mechanism 20 of the peeling section 110 will be explained. The pasting mechanism 20 includes an adhesive tape guide 21 , a bag storage tube 23 , a guide plate 24 , a bag holding stand 25 , and a stand vertical movement mechanism 26 .

The pre-peeling bag E is housed in the bag housing cylinder 23. Specifically, a large number of pre-peeling bags E stacked in the bag thickness direction BTH are placed on the bag holding stand 25 inside the rectangular cylindrical bag storage tube 23. The bag holding table 25 is movable in the vertical direction by a table vertical movement mechanism 26, as shown by double-headed arrows in FIG. In FIG. 7, the pre-separation bags E in the bag storage cylinder 23 are arranged such that the flap EF and release tape SFT are located on the left side in the figure, and the bottom edge EBB is located on the right side in the figure. . It should be noted that among the many pre-peeling bags E stacked and stored in the bag storage cylinder 23, the bag located at the top and from which the peeling tape SFT will be peeled off next by the peeling section 110 is placed in the topmost bag before peeling. Let's call it bag E1. In the bag storage tube 23, the bottom edge 23BU of the bottom side surface 23B, which is in contact with the bottom edge EBB of the pre-peel bag E, is attached as the pre-peel bag E1 is moved, as will be described later. A guide plate 24 is provided to guide the EBB to the roll nip 31N of the feed roll pair 31.

On the other hand, above the bag storage cylinder 23, an adhesive tape guide 21 is arranged, which is a member that guides the movement of the adhesive tape AT in the longitudinal direction ALH to the downstream ALD and the upstream ALU (see FIG. 7). . The adhesive tape AT is attached to the unwinding shaft 41, and passes through each surface of the adhesive surface guide part 21A, the adhesive part forming part 21B, and the pasted part guide part 21C, which are the lower parts of the adhesive tape guide 21 in FIG. It slides and is wound up in a spiral shape on the winding shaft 42.

This adhesive tape AT is formed by forming an adhesive layer (not shown) on one side of a band-shaped tape base material made of paper, cloth, cellophane, OPP or other resin film, and winding the tape into a spiral shape. When the adhesive surface ATS of the adhesive tape AT is attached to the outer surface SFTS of the release tape SFT of the pre-peel bag E, the adhesive surface ATS of the adhesive tape AT can be firmly attached to the release tape SFT from the adhesive part EFG while remaining adhered to the release tape SFT. It has adhesive strength that allows it to be peeled off.

In the adhesive tape guide 21, a flat sloped portion located on the lower left side in FIG. 7 and facing the lower left side is the adhesive surface guide portion 21A. An adhesive tape AT, which is unwound from a roll of adhesive tape AT attached to the unwinding shaft 41 and has an exposed adhesive surface ATS, is disposed in contact with the adhesive surface guide portion 21A. Note that the adhesive surface ATS of the adhesive tape AT also faces outward from the adhesive tape guide 21, that is, toward the lower left side in FIG.

On the other hand, of the adhesive tape guide 21, a flat sloped portion located on the lower right side in FIG. 7 and facing the lower right side is the pasted portion guide portion 21C. A pasted adhesive tape portion ATR of the adhesive tape AT that is wound around the winding shaft 42 is disposed in contact with the pasted region guide portion 21C. The slope of the pasted part guide section 21C is gentler than the slope of the adhesive surface guide section 21A. As will be described later, this is to move the pre-peel bag E1 largely to the right in FIG. 7 without lifting it too high when positioning the pre-peel bag E1 at the set position PS.

In addition, as shown in FIG. 7, in the applied adhesive tape part ATR, a part of the peeled release tape ST peeled off from the pre-peeling bag E is lined up and stuck to the adhesive surface ATS of the adhesive tape AT. There is.

In the adhesive tape guide 21, a gently arcuate downward facing portion located between the adhesive surface guide portion 21A and the pasted portion guide portion 21C is the adhesive portion forming portion 21B. An adhesive tape AT with an exposed adhesive surface ATS is placed in contact with this adhesive portion forming portion 21B as well, and a loose arc-shaped adhesive portion ATP with the adhesive surface ATS facing downward is arranged, following the adhesive portion forming portion 21B. It is said that

Next, a description will be given of the peeling mechanism 30 of the peeling section 110 that peels off the peeling tape SFT from the adhesive part EFG of the pre-peeling bag E1. The peeling mechanism 30 includes a pair of feed rolls 31 and a suction conveyor 33. Among these, the feed roll pair 31 consists of an upper feed roll 31A and a lower feed roll 31B. The two rolls 31A and 31B are in contact with each other to form a roll nip 31N. The upper feed roll 31A and the lower feed roll 31B forming the feed roll pair 31 are rotationally driven by a drive mechanism (not shown), and as described later (see FIG. 9), the pre-peeling bag E1 is placed at the set position PS. That is, when the bottom edge EBB of the pre-peel bag E1 is inserted into the roll nip 31N, the bag is configured as a bag moving mechanism that sandwiches the pre-peel bag E1 and feeds it toward the right side in FIG. 9.

Further, in FIG. 7, a suction conveyor 33 is arranged downstream (on the right side) of the feed roll pair 31. The suction conveyor 33 includes a suction belt 34 having a large number of intake holes (not shown), an intake section 35 that sucks air AR through the suction belt 34, and a belt drive roll 36 that drives the suction belt 34. There is.

Of the pair of feed rolls 31, the surface 31AS of the upper feed roll 31A is subjected to a non-adhesive surface treatment such as fluororesin treatment so that the glue portion EFG of the pre-peel bag E from which the release tape SFT has been removed does not stick. ing. Alternatively, as shown by broken lines in FIG. 7, etc., a groove 31AR extending in the axial direction of the roll (direction perpendicular to the plane of paper in FIG. 7) is provided in a part of the surface 31AS of the upper feed roll 31A, and the glue portion The EFG may be prevented from contacting the upper feed roll 31A.

Next, the adhesive tape moving mechanism 40 of the peeling section 110 will be explained. The adhesive tape moving mechanism 40 includes an unwinding shaft 41, a winding shaft 42, an unwinding motor 43, and a winding motor 44. Among these, the unwinding shaft 41 to which the adhesive tape AT wound in a roll is attached is driven and controlled by an unwinding motor 43 such as rotation and stopping. The adhesive tape AT unwound by the rotation of the unwinding shaft 41 advances to the downstream ALD via the adhesive surface guide portion 21A of the adhesive tape guide 21 described above, and is peeled off from the pre-peeling bag E1. The release tapes ST are lined up in order to form an applied adhesive tape portion ATR, which is wound around the winding shaft 42. This winding shaft 42 is driven and controlled by a winding motor 44.

In the peeling section 110 of the present embodiment, a single adhesive wire spanned between the uppermost pre-peeling bag E1 housed in the bag storage tube 23 and the unwinding shaft 41 and the winding shaft 42 In the tape AT, when viewed from above, the longitudinal direction ALH in which the adhesive tape AT extends is substantially parallel to the bag depth direction BDH of the bag E1 before peeling. Moreover, the entire width of the adhesive tape AT is arranged so as to overlap the pre-peel bag E1. That is, since the adhesive tape AT does not protrude outward in the bag width direction BWH from the one side edge ES1 or the other side edge ES2, it does not stick to the pre-peel bags E other than the topmost pre-peel bag E1. , the possibility of feeding a plurality of pre-peel bags E in a stacked manner or failing to peel off the release tape SFT of the pre-peel bag E1 is suppressed.

Next, a description will be given of the peeling step S1 according to the present embodiment, specifically, the removal of the release tape SFT of the pre-peel bag E (the uppermost pre-peel bag E1) using the peeling unit 110 of the enclosing device 100. As described above, a large number of pre-peeling bags E are stored in the bag storage cylinder 23. Further, the unwinding motor 43 and the winding motor 44 control the rotation of the unwinding shaft 41 and the winding shaft 42, and control the amount of unwinding of the adhesive tape AT and the tension applied to the adhesive tape AT to guide the adhesive tape. 21, the adhesive tape AT is brought into contact with the adhesive surface guide part 21A, the adhesive part forming part 21B, and the pasted part guide part 21C. In addition, the adhesive tape AT in contact with the adhesive surface guide portion 21A and the adhesive portion forming portion 21B is in a state in which the adhesive surface ATS thereof is exposed outward. As described above, the portion of the adhesive tape AT that comes into contact with the adhesive portion forming portion 21B of the adhesive tape guide 21 is referred to as the adhesive portion ATP.

On the other hand, among the adhesive tapes AT, the adhesive tape AT in the part that contacts the pasted part guide part 21C of the adhesive tape guide 21 and in the downstream ALD is removed after peeling off the release tape SFT of a large number of pre-peel bags E. As shown in FIG. 7 and the like, a portion of the peeled release tape ST forms a pasted adhesive tape portion ATR that is lined up and stuck in order.

In this state, using the table vertical movement mechanism 26, the bag holding table 25 holding the pre-peel bags E is raised, and the peel tape SFT of the pre-peel bag E1 which is the highest among the many pre-peel bags E is removed. (see FIG. 1) is pressed against the adhesive area ATP of the adhesive tape AT. This causes the adhesive portion ATP of the adhesive tape AT to adhere to the outer surface SFTS of the release tape SFT. The adhesive area ATP of the adhesive tape AT becomes an adhered area ATQ to which the release tape SFT has adhered.

Thereafter, when the bag holding table 25 is lowered by the table vertical movement mechanism 26, as shown in FIG. Therefore, the vicinity of the flap EF of the pre-peeling bag E1 is in a lifted position. On the other hand, the pre-peel bags E other than the uppermost pre-peel bag E1 are lowered as the bag holding table 25 is lowered (see FIG. 8). That is, only the uppermost pre-peel bag E1 is selected by the adhesive tape AT, and becomes movable together with the pasted part ATQ of the adhesive tape AT.

Therefore, the rotation of the unwinding shaft 41 and the winding shaft 42 is controlled by the unwinding motor 43 and the winding motor 44 to unwind the adhesive tape AT, and as shown in FIG. The region ATQ is moved to the downstream side ALD (upper right side in FIG. 9) along the pasted region guide portion 21C of the adhesive tape guide 21, and the uppermost pre-peeling bag E1 is also moved to the right side in the figure. . Then, the bottom edge EBB of the pre-peeling bag E1 is guided by the guide plate 24 and moved to the set position PS where it reaches the roll nip 31N of the feed roll pair 31. Thereby, the bag before peeling E1 can be moved by the pair of feed rolls 31. As can be understood from this explanation, the adhesive tape moving mechanism 40 including the unwinding shaft 41 and the like is a bag setting mechanism that moves the pre-peeling bag E1 to the setting position PS where it can be moved by the feed roll pair 31 (bag moving mechanism). It also serves as

The pre-peeling bag E1 that has been moved to the set position PS is sandwiched between the pair of feed rolls 31 and sent to the right side in the figure. On the other hand, the unwinding shaft 41 and the winding shaft 42 are locked unrotatably by the motors 43 and 44, so that the adhesive tape AT is immovable. Therefore, the release tape SFT adhering to the applied part ATQ of the adhesive tape AT was peeled off from the pre-peel bag E1 as the pre-peel bag E1 moved to the right in the figure, and the adhesive part EFG was exposed. This becomes an exposed glue bag Ege (see FIGS. 10 and 2).

The exposed glue bag Ege discharged from the pair of feed rolls 31 is further sent to the downstream side (right side) in FIG. 10 while being attracted to the suction belt 34 of the suction conveyor 33.

Note that the peeled off release tape SFT remains adhered to the applied part ATQ of the adhesive tape AT as a peeled release tape ST. Therefore, the peeled release tape ST cannot move freely and is wound up on the winding shaft 42 together with the applied adhesive tape portion ATR of the adhesive tape AT. Therefore, the peeled release tape ST can be disposed of compactly and easily.

After peeling off the release tape SFT from the pre-peeling bag E1, the rotation of the unwinding shaft 41 and the winding shaft 42 is controlled by the unwinding motor 43 and the winding motor 44, and the adhesive tape AT is rewound to the upstream side. Move it to the side ALU. However, once again, the adhesive surface ATS of the adhesive tape AT is exposed outwardly in contact with the adhesive part forming portion 21B of the adhesive tape guide 21, and forms an adhesive part ATP to which the release tape SFT can be attached. Adjust the rewind amount.

Next, in the peeling check step S2 according to the present embodiment, specifically, using the peeling checking unit 120 of the enclosing device 100, it is determined whether the peeling tape SFT can be peeled off from the pre-peeling bag E (the uppermost pre-peeling bag E1). Detection of whether this is the case will be explained with reference to FIG. The peeling check unit 120 is arranged above the suction conveyor 33, and is a first peeling unit that detects whether or not there is a peeling tape SFT covering the glue portion EFG in the glue exposed bag Ege conveyed by the suction conveyor 33. It includes a tape sensor 121 and a peeling check control section 122 that controls the tape sensor 121 and determines whether or not a peelable tape SFT exists. Note that the first release tape sensor 121 may be any sensor that can detect the presence or absence of the release tape SFT covering the adhesive portion EFG, such as a reflective optical sensor, a transmission optical sensor, an ultrasonic sensor, or an adhesive sensor. A camera that images the EFG and an image processing device that determines the presence or absence of the release tape SFT on the flap EF from the captured image may be used.

Here, if the first release tape sensor 121 detects the release tape SFT on the adhesive part EFG, peeling off of the release tape SFT fails and the bag being conveyed by the suction conveyor 33 is not removed. It can be determined that the release tape SFT, which should have been removed, is a defective bag Eng remaining on the adhesive portion EFG. Therefore, the result is No in the peeling check step S2.

On the other hand, if the release tape SFT is not detected on the adhesive part EFG, the release tape SFT is successfully peeled off, and the bag being conveyed by the suction conveyor 33 is removed and the release tape SFT is removed from the adhesive part EFG. It can be determined that this is an exposed glue bag Ege. Therefore, the answer is Yes in the peeling check step S2.

In addition, instead of using the first release tape sensor 121 to detect the presence or absence of the release tape SFT covering the glue portion EFG of the glue exposed bag Ege being conveyed by the suction conveyor 33, or in addition to this, the broken line shown in FIG. The second release tape sensor 123 shown in may be used to detect whether or not the peeled release tape ST peeled off from the pre-peeling bag E1 is present on the adhesive tape AT of the peeling section 110. This second release tape sensor 123 may be any sensor that can detect the presence or absence of the peeled release tape ST, such as a reflective optical sensor, a transmission optical sensor, an ultrasonic sensor, or a camera that images the adhesive tape AT. An image processing device or the like may be used that determines the presence or absence of the peeled release tape ST on the adhesive tape AT from the captured image.

Next, the discharge step S3 according to the present embodiment, specifically, the discharge of the defective bag Eng using the discharge section 130 of the enclosing device 100 will be described with reference to FIG. The discharge section 130 generally includes a suction conveyor 135, a bag moving discharge section 132, and a discharge control section 131 that controls the driving of these sections. The suction conveyor 135 conveys the exposed glue bag Ege following the aforementioned suction conveyor 33, and passes the exposed glue bag Ege to the following suction conveyor 38.

Similar to the suction conveyor 33 described above, the suction conveyor 135 also has a suction belt 136 having a large number of intake holes (not shown), an intake section 137 that sucks air AR through the suction belt 136, and drives the suction belt 136. It has a belt drive roll 138 and a belt driven roll 139. Note that the discharge control section 131 also controls the intake of air AR in the intake section 137 and the drive control of the belt drive roll 138. On the other hand, the bag moving and discharging unit 132 includes discharge suction cups 133A, 133B, and a lifting and moving unit 134 that lifts the discharge suction cup 133A and moves it to a discharge site (not shown), and these controls are also controlled by the discharge control. This is done in section 131.

First, if Yes in the peeling check step S2, that is, if the peeling checking section 120 determines that the bag being conveyed by the suction conveyor 33 is an exposed glue bag Ege, the bag moving and discharging section 132 is not operated. The exposed glue bag Ege is delivered to the suction conveyors 33, 135, and 38 in this order, and continues to be transported toward the insertion section 140, which will be described later.

On the other hand, if No in the peeling check step S2, that is, if the peeling check section 120 determines that the bag being conveyed by the suction conveyor 33 is a defective bag Eng, as shown in FIG. is positioned on the suction belt 136 of the suction conveyor 135, the discharge suction cups 133A and 133B are respectively adsorbed to the bag body part EB of the defective bag Eng, the suction by the suction part 137 is stopped, and the suction belt 136 is placed on the suction belt 136. The defective bag Eng can be removed from the bag. Further, the lifting and moving unit 134 lifts the discharge suction cups 133A, 133B and the defective bag Eng sucked thereto and moves them to the discharge site. At a discharge site such as a collection box (not shown), suction by the discharge suction cups 133A and 133B is stopped, and the defective bag Eng is separated and discharged. In addition, instead of discharging the defective bag Eng by the above-mentioned lifting and moving unit 134, the defective bag Eng may be discharged by other methods such as blowing the defective bag Eng toward the collection box using compressed air and discharging it. Also good.

In this way, the defective bag Eng is ejected and transported to the insertion section 140, which will be described later, and the postcard CN is prevented from being inserted therein. Furthermore, even if the peeling tape SFT fails to be peeled off from the pre-peeling bag E1, it is sufficient to discharge and discard only the defective bag Eng before inserting the postcard CN. Therefore, losses due to failure in peeling off the release tape SFT can be reduced compared to the conventional method. Further, there is no need to collect the contents such as postcards CN from defective products in which postcards CN have been inserted into the bag, and the trouble of collecting them can be eliminated.

Next, the insertion step S4 according to the present embodiment, specifically, the insertion of the postcard CN into the adhesive exposed bag Ege using the insertion section 140 of the enclosing device 100 will be described with reference to FIG. As described above, the insertion section 140 includes an opening mechanism 150 that opens the bag entrance EBO of the bag body section EB of the adhesive exposed bag Ege conveyed from the peeling section 110, and inserts the postcard CN into the bag body section EB through the bag entrance EBO. It has a postcard insertion mechanism 160 for inserting a postcard, and a contact prevention mechanism 170 for preventing contact between the inserted postcard CN and the adhesive portion EFG of the flap EF.

Of these, the opening mechanism 150 has a large number of intake holes (not shown), and sucks the first body part EB1 and the flap EF on the lower side in the figure of the bag body part EB of the adhesive exposed bag Ege placed thereon. Then, the suction table 151 that holds the adhesive exposed bag Ege, the suction part 152 that sucks air AR through the suction table 151, and the bottom edge EBB of the bag body part EB of the adhesive exposed bag Ege are brought into contact with each other to expose the adhesive. It has a bottom abutment plate 153 for positioning the bag Ege. Furthermore, it is attracted to the second entrance part EB2I near the bag entrance EBO of the second main body part EB2 on the upper side in the figure of the bag body part EB, and the second entrance part EB2I is circularly moved as shown by the double-headed arrow in the figure. It also has a lifting suction cup 155 that lifts up along an arcuate trajectory to open the bag entrance EBO, and a drive control section 156 that controls suction and movement of the suction part 152 and the lifting suction cup 155.

As described above, the first main body part EB1 on the lower side in the figure of the bag main body part EB is entirely sucked and held by the suction table 151, so that the first main body part EB1 near the bag entrance EBO of the first main body part EB1 is 1 inlet portion EB1I is also sucked and held by the suction table 151. Therefore, by lifting the second entrance portion EB2I using the lifting suction cup 155, the bag entrance EBO can be opened.

The postcard insertion mechanism 160 also includes a separator-cum-guide plate 161 that inserts the tip end 161S into the open bag entrance EBO of the adhesive exposed bag Ege and guides the insertion into the postcard CN, and a rear end CNB of the postcard CN (see Fig. It has a pusher 162 that presses the postcard CN to move it in the direction shown by the arrow in the figure and inserts the postcard CN into the bag body part EB of the glue-exposed bag Ege through the bag entrance EBO. In this embodiment, the separator/guide plate 161 also serves as a contact prevention mechanism 170 that is interposed between the inserted postcard CN and the adhesive portion EFG of the flap EF to prevent them from coming into contact with each other. It is preferable that at least a portion of the separator/guide plate 161 located near the adhesive portion EFG of the flap EF be made of a material to which the adhesive portion EFG is difficult to adhere, or that it be subjected to a non-adhesive treatment.

Using this insertion part 140, the insertion step S4 of inserting the postcard CN into the adhesive exposed bag Ege is performed as follows. First, in the opening step S41, the exposed glue bag Ege is conveyed to the suction table 151, the bottom edge EBB is brought into contact with the bottom contact plate 153 to position the exposed glue bag Ege, and the adhesive exposed bag Ege is removed by the suction part 152. The exposed bag Ege is suctioned and held on the suction table 151. Next, the lifting suction cup 155 is attracted to the second entrance part EB2I of the second main body part EB2 of the bag body part EB, and the lifting suction cup 155 and the second entrance part EB2I are moved along an arcuate trajectory as shown by the double-headed arrow in the figure. Pass through and lift it up to open the bag entrance EBO of the bag main body EB.

Furthermore, as a postcard insertion step S42 of the insertion step S4, the tip portion 161S of the separator/guidance plate 161 is inserted into the opened bag entrance EBO. As a result, the adhesive portion EFG of the flap EF is covered by the separator-cum-guidance plate 161, so that it is possible to prevent the postcard CN from sticking to the adhesive portion EFG when inserting the postcard CN, which will be described below.

Thereafter, the pusher 162 pushes the rear end CNB of the postcard CN placed on the separator/guidance plate 161, moves the postcard CN to the right side in the figure, and inserts the postcard CN into the bag main body EB through the bag entrance EBO. do. As a result, an inserted bag Ein is formed (see FIG. 3).

In performing the insertion step S4 of this embodiment, the insertion section 140 of the enclosing device 100 includes an opening mechanism 150, a postcard insertion mechanism 160, and a contact prevention mechanism 170, so that the adhesive section EFG is attached to the flap EF. Even though the adhesive exposed bag Ege is formed and the release tape SFT is peeled off, the postcard CN can be inserted into the bag body part EB without causing a problem of sticking to the adhesive part EFG.

Furthermore, in the enclosing step S5 according to the present embodiment, specifically, the flap EF of the inserted bag Ein is fixed to the bag main body part EB via the glue part EFG using the enclosing part 180 of the enclosing device 100. , a prepackaged postcard EC in which a postcard CN is enclosed in a prepackaged bag Een can be manufactured. Note that this encapsulation step S5 can be performed using the same method as the encapsulation step performed after inserting the postcard CN into the conventional pre-peel bag E and peeling off the release tape SFT, so a detailed explanation will be omitted. do.

(Deformed form)
In the enclosing device 100 of the above-described embodiment, the suction table 151 having a flat upper surface is used in the insertion section 140 (see FIG. 12) to flatten not only the bag body part EB but also the flap EF of the exposed glue bag Ege placed thereon. keep and hold. Then, the tip 161S of the separator-cum-guiding plate 161 is inserted into the opened bag entrance EBO, and the separator-cum-guiding plate 161 is used to prevent contact between the inserted postcard CN and the adhesive part EFG of the flap EF. It also serves as the mechanism 170. Then, the pusher 162 pushes the rear end CNB of the postcard CN, moves it on the separator/guidance plate 161, and inserts the postcard CN into the bag main body EB through the bag entrance EBO.

On the other hand, in the insertion section 240 of the enclosure device 200 used in the insertion step S4 of this modification, as shown in FIG. 13, a suction table 251 with a flat top surface is used as the opening mechanism 250, as in the embodiment. The size is such that only the bag main body part EB of the placed adhesive exposed bag Ege can be held flat. That is, the flap EF of the adhesive exposed bag Ege is not held on the suction table 251.
In this case as well, similarly to the embodiment, the second entrance portion EB2I can be lifted by the lifting suction cup 155 to open the bag entrance EBO of the bag main body portion EB.

On the other hand, the insertion section 240 of this modified form includes, as a contact prevention mechanism 270, a warping suction cup 273 and a suction cup drive control section 274 that drives and controls the warping suction cup 273. The flap EF, which protrudes to the left in the figure from the suction table 251, is sucked by the warp suction cup 273, and as shown by the double-headed arrow in the figure, the flap EF protrudes to the left in the figure. Curl it into an arc shape.

Further, the insertion section 240 has a guide plate 261 having a tip end 261S and a pusher 262 as a postcard insertion mechanism 260. Then, insert the tip end 261S of the postcard insertion mechanism 260 into the opened bag entrance EBO of the adhesive exposed bag Ege, push the rear end CNB of the postcard CN with the pusher 262 and move it in the direction shown by the arrow in the figure, and then Insert the postcard CN into the bag body part EB of the adhesive exposed bag Ege through the EBO.

In this way, in addition to the guide plate 261 of the postcard insertion mechanism 260, the contact prevention mechanism 270 may be used to prevent the inserted postcard CN from coming into contact with the adhesive portion EFG of the flap EF. It is more preferable that at least a portion of the guide plate 261 near the adhesive portion EFG of the flap EF is made of a material to which the adhesive portion EFG is difficult to adhere, or is subjected to a non-adhesive treatment.

Although the present invention has been described in accordance with the embodiments and modified forms, the present invention is not limited to the above-described embodiments, etc., and can be applied with appropriate changes without departing from the gist thereof. Needless to say.
For example, in the peeling part 110, an example using an adhesive tape guide 21 in which the surfaces of the adhesive surface guide part 21A on which the adhesive tape AT slides, the adhesive part forming part 21B, and the pasted part guide part 21C are formed on the lower part. showed that. However, instead of this, a plurality of rolls are used and each roll is arranged so that the adhesive tape AT stretched between these rolls moves in the same way as sliding on each part of the adhesive tape guide 21. You may do so.

In the embodiment, while the adhesive tape guide 21 of the pasting mechanism 20 is left still, a large number of glued bags E are stacked and stored on the bag holding stand 25 in the bag storage tube 23, and the bag holding stand 25 holds the adhesive tape guide 21 still. A large number of glued bags E are raised, and the release tape SFT of the topmost number of glued bags E1 is adhered to the adhesive part ATP of the adhesive tape AT to form a pasted part ATQ. 25, each glued bag E was lowered.
However, instead of stacking and accommodating a large number of glued bags E in the bag storage tube 23 in the pasting mechanism, for example, a transfer mechanism such as a suction conveyor is used to sequentially attach the individual glued bags E. The tape is transferred below the tape guide 21. Thereafter, the flap EF of the single glued bag E is raised, or the adhesive tape guide 21 is lowered to make the release tape SFT of the glued bag E stick to the adhesive part ATP of the adhesive tape AT, and the pasted part is removed. After forming the ATQ, the single adhesive bag E may be lowered or the adhesive tape guide 21 may be raised.
Furthermore, the transfer mechanism such as the above-mentioned suction conveyor is also used as a peeling mechanism (bag moving mechanism), and this transfer mechanism transfers the glued bag E further downstream to the area ATQ where the adhesive tape AT has been pasted. The release tape SFT may be peeled off from the adhesive portion EFG by causing relative movement of the adhesive bag E.

Further, in the embodiment and the modified form, in the postcard insertion mechanism 160, 260 of the insertion section 140, 240, the pusher 162, 262 pushes the rear end CNB of the postcard CN to move the postcard CN in the direction shown by the arrow in the figure. . However, as shown in the circle in FIGS. 12 and 13, by pushing the rear end CNB of the postcard CN in the direction of the arrow in the figure with the L-shaped movable claw part 163 or the reverse L-shaped movable claw part 164, the postcard can be removed. The postcard CN may be moved in the direction shown by the arrow in the figure, and the postcard CN may be inserted into the bag body portion EB of the glue-exposed bag Ege through the bag entrance EBO.

In the embodiment and the modified form, the tips 161S, 261S of the guide plates 161, 261 are inserted into the open bag entrance EBO of the exposed glue bag Ege, and the postcard CN is inserted into the bag body part EB of the exposed glue bag Ege. Inserted. However, it is only necessary to prevent the inserted postcard CN from coming into contact with the glue part EFG of the flap EF by sufficiently bending the flap EF, etc. It can also be arranged so that it is not inserted into the entrance EBO.
