[0005] In such a field of use, the biggest technical problem in automating the conventional manual work is how to quickly remove this release tape. It is essential to streamline and automate the entire series of processes, including the process of filling in envelopes. In other words, if a series of processes from removal of the release tape to bending adhesion of the flap can be performed, it will be possible to open the way to automate all the steps of this kind of work.

Therefore, the present invention provides a new method for achieving high-speed removal of the release tape and a new series of methods for peeling and removing the release tape and folding and sealing the flap portion of the envelope in the field of use. provide. In other words, the conventional method is an ordinary method in which the peeling tape is peeled off in the extending direction, while the present invention is an automatic technique for peeling and removing the peeling tape at once in the width direction, and a continuous flap. A series of automated technologies that provide a folding mechanism for sealing. Means for solving the problem

[0006] That is, the peeling device for the envelope with a tape of the present application engages with the tape sticking surface of the envelope. The tape is peeled off by moving the envelope relatively toward the bottom of the envelope while being engaged (Claim 1).

And a tape peeling device for a tape-equipped envelope that engages with a tape adhering surface of the envelope and relatively moves the envelope toward the bottom of the envelope while being engaged. A plurality of claw portions protruding toward the upstream side in the moving direction are provided in a direction in which the tape extends, and a sticking surface support portion that supports the tape sticking surface at a predetermined interval in the width direction of the tape. Further, it is characterized in that an air intake opening that is elongated in the direction in which the tape extends is provided between the claw portion and the sticking surface support portion (claim 2).

Furthermore, the claw portion, the sticking surface support portion, and the air inlet are integrally formed, and further provided with a movable mechanism so as to be freely engageable with the tape sticking surface of the envelope. 3).

[0007] On the other hand, when the tape attachment surface is the inner surface of the flap portion of the envelope, the restriction that engages the outer surface of the envelope flap portion in the vicinity of the claw portion and restricts the free deformation of the flap portion. It is characterized in that it is provided with a member (claim 4).

In this case, the regulating member is configured to be engageable with the outer surface of the envelope flap portion (claim 5).

[0008] Then, the sealing device for an envelope with a tape of the present application includes a transport path for transporting the envelope bottom portion as a leading end, a tape peeling stage and a flap bonding stage are provided on the way, and the tape peeling stage transports the envelope 6. A means for temporarily stopping the tape, and engaging the inner surface of the envelope flap during the stop, and restarting the transport while being engaged to release the peeling tape. In addition, the flap adhering stage is provided with a means for temporarily stopping the conveyance of the envelope and a folding adhesion mechanism for folding and adhering the envelope flap during the stop. (Claim 6).

The invention's effect

[001 1] According to the tape peeling apparatus of the present invention, there is an effect that the peeling tape on the envelope can be removed in a very short time. In other words, compared to the conventional method in which the entire length of the extending tape is peeled off, the device of the present application is a method that peels in a much shorter width direction, and between the nail portion and the sticking surface support portion. Because it has a configuration that forms a long and narrow air inlet, it can be peeled off with a short moving distance and can be removed by suction instantly.

In addition, according to the tape sealing device according to the present invention, the peeling tape is peeled off at once by the peeling device, and the folding part is bent and bonded in the same direction. You can finish the sealing process.

In addition, these are devices that can be completed in a series of transport paths, and can be extended to the preceding product encapsulation process, contributing to mechanization and automation throughout the entire encapsulation and sealing process.

In addition, in the case of the configuration provided with the above-mentioned regulating member, even the envelope flap in a state accompanied by some deformation because of the thin film is engaged with the claw portion. There is an effect of adjusting the condition, and the present invention can be implemented stably in practice. Further, according to the bending bonding mechanism configured as described above, since the entire width direction of the flap portion can be bent and bonded at the same time, it is possible to achieve a beautiful sticking without wrinkles.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a preferred embodiment will be described with reference to FIGS. 1 to 5 shown in time series and FIG. 8 showing only a main part in a perspective view for easy understanding.

First, the conveyance path of the present apparatus will be described.

In the figure, reference numeral 10 denotes a first table, and in this example, it is provided with a conveying means composed of a carry-in roll 11 and a pinch roll 13. Reference numeral 20 denotes a second table, which is provided with a conveying means comprising a conveying belt 21 stretched around pulleys 22 and 22a and pinch rolls 23 and 24 related thereto. Further, reference numeral 30 denotes a third table, which is provided with a conveying means including a conveying belt 31 stretched around pulleys 32 and 32a and pinch rolls 33 and 34 related thereto. These conveying means are used to form a series of conveying paths as shown.

[0014] The pinch rolls 13, 23, 33 are always urged by means such as a panel, and each time the envelopes 1a, 1b, 1c arrive, the pinch rolls 13, 23, 33 are rotated while being elastically pressed. The pinch rolls 24 and 34 are respectively attached to the roll arms 25 and 35, and can be pressed or released at a predetermined timing by swinging the roll arm fulcrum shafts 26 and 36. is there.

[0015] Although such a transport means is provided to form a transport path, a tape peeling stage and a flap bonding stage are formed on the way. Then, the stoppers 27 and 37 can be operated in a timely manner together with the pinch rolls 24 and 34 with respect to the envelopes 1 b and 1 c arriving one after another, thereby positioning and stopping the envelope within the stage. In addition, although not shown, the means for operating at a predetermined timing is constituted by a known technique such as a cam mechanism.

[0016] Next, detailed description of the conveyance of the envelope and the tape peeling at the tape peeling stage. To do.

Fig. 1 illustrates the situation where envelope 1G is being transported from left to right on the page. That is, it is transported on the first table 10 by the carry-in port 11 and the pinch port 13, and then sandwiched between the pinch roll 24 and the transport belt 21 and continuously transported to the second table 20. It is in the state.

FIG. 2 illustrates a state when the bottom leading end of the envelope 1 c reaches the stopper 27. That is, this state is a state in which the envelope 1 c is stopped in the tape peeling stage, the roll arm fulcrum shaft 26 is operated, and the pinch roll 24 that has pressed the envelope 1 c through the roll arm 25 is moved. The carriage has been lifted somewhat and released. FIG. 3 illustrates a state in which the peeling mechanism 40 embodying the tape peeling device of the present invention from the lower side and the regulating plate 14 from the upper side with respect to the envelope flap portion while the envelope 1 c is stopped. . The peeling mechanism 40 is connected to the arm fulcrum shaft 18 via the peeling arm 17, and similarly, the restriction plate 14 is connected to the arm fulcrum shaft 16 via the restriction plate arm 15. When the envelope 1G stops, the flap is connected. It is in a state of being immediately closed from above and below toward the part.

Next, as shown in FIG. 4, from the state where the conveyance of the envelope 1 G is interrupted, the stopper 27 is lowered, the pinch roll 24 is also lowered as shown in the figure, and the conveyance of the envelope 1 G is resumed. It is shown. The stopper 27 descends when the arm fulcrum shaft 29 swings through the stopper arm 28. Similarly, the pinch roll 24 operates by the shaft swing of the roller lure fulcrum shaft 26. Here, it should be noted that the peeling mechanism 40 removes the peeling tape existing in the envelope flap portion under this state. In the figure, reference numeral 41 denotes an airflow arrow, which illustrates that the peeling tape 3 is sucked and discharged from the air inlet formed in the peeling mechanism 40 as described later.

FIG. 5 shows a situation where the envelope 1 c continues to be conveyed even after the release tape 3 is removed. That is, during the transition from the state shown in FIG. 3 to the state shown in FIGS. 4 to 5, the peeling mechanism 40 is used to remove the peeling tape 3, and the peeling is almost completed as shown in FIG. As described above, the peeling mechanism 40 and the regulating plate 14 are opened to return to the initial position shown in FIG. In other words, the state of Figure 5 is a cycle operation It is a state diagram of the final stage, that is, a state where the next envelope 1d is received. Therefore, for the envelopes that arrive one after another, the operation from FIG. 1 to FIG. 5 described above is repeated, and the peeling tape 3 can be efficiently removed with only a small loss of stop time that remains on the tape peeling stage.

[0020] Here, the envelope 1 with tape will be described with reference to FIG. For ease of explanation, a state in which the flap portion 2 of the envelope 1 is positioned on the lower side is shown. In the figure, 4 indicates the glue part, and S2 indicates the glue width, which is generally 6 to 10 countries wide and is applied over the entire width of envelope 1. The glue part 4 is covered and protected with a thin film-like release tape 3, and the tape width S1 is generally 20 to 25 countries. S3 indicates the flap length of the flap 1a, and generally there are about 25-50 countries.

Needless to say, the width and depth of the envelope 1 are determined in accordance with the size of the article to be encapsulated, but the specifications of the flap portion are generally similar.

[0021] Next, the peeling mechanism 40 will be described in detail.

FIG. 9 is an external view of a peeling mechanism 40 according to a preferred embodiment, and FIG. 10 is an explanatory view of a virtually disassembled state. In this example, the claw part 5, the flap inner surface support part 6 and the air inlet 7 are formed by two parts. Further, the claw portion 5 is formed into a claw shape (tongue piece shape) by taking the “-” portion of the claw plate 8 and is formed at three locations with an appropriate distance. Further, the claw portion 5 is not necessarily formed integrally with the claw plate 8, and can be formed as a separate part if necessary.

In FIG. 10, the air flow is shown by arrows. That is, the lower suction port of the peeling mechanism 40 is connected to a suction device (not shown) such as a blower so that an air flow as shown is generated. As a result, air can flow from the long and narrow intake port 7 formed facing the claw portion 5, or the vicinity of the intake port 7 can be in a negative pressure state.

[0023] Based on Fig. 11, preferred specifications based on the research results are disclosed for the main part of the peeling mechanism 40. In the figure, 1 is the edge clearance angle of the claw, 2 is the edge angle of the edge, and according to many experiments, the clearance angle 1 is in the range of _20-30 °, preferably _5 ~ 15 °. With regard to the blade angle, the blade is killed by puffing or the like without sharpening the blade edge, and is about 15 to 40 °, preferably 20 to 32 °. Of course, the nail part 5 is subjected to a surface treatment such as puffing or Teflon (registered trademark) processing, and has a surface characteristic and a shape that does not cause significant frictional resistance because it contacts the glue part made of adhesive. Is preferred.

On the other hand, as shown in FIG. 12, the flap inner surface support portion 6 is provided to abut against the inner surface of the flap and support the flap portion 2 under the negative pressure action by the intake port 7. In the figure, S6 indicates the height of the claw with reference to the flap inner surface support 6 and is approximately _5 to 12 countries, preferably _2 to 5 countries. The claw length S5 is about 2-15 countries, preferably 4-10 countries, and the claw opening width S4 is about 3-25 countries, preferably about 6-12 countries.

FIG. 12 shows an example of an embodiment of a flap glue type envelope in which a peeling tape 3 is adhered to the flap portion 2, but the inner surface of the flap is similarly supported for the above-mentioned trunk glue type envelope. What is necessary is just to make the part 6 contact | abut to the surface (envelope trunk | drum) to which the peeling tape 3 was stuck as a sticking surface support part, and to exhibit a support function.

[0025] In the illustrated embodiment mechanism, the sum of the claw opening width S4 and the claw length S5 corresponds to the mouth width of the intake port 7 referred to in the present application, and the claw formed on the claw plate 8 It is formed in an elongated shape along the arrangement of part 5. In other words, at least the claw portion 5 and the flap inner surface support portion 6 are provided, and the intake port 7 for generating a negative pressure or a suction air flow is provided therebetween.

Accordingly, the width of the air inlet 7 is sufficient to support the flap inner surface support 6 and is about 5 to 40 countries, preferably about 6 to 15 countries.

Of course, it is desirable that the length of the flap part 2 is less than the length of the flap part 2, but if necessary, it may be configured longer than that o

Next, an embodiment in which the peeling tape 3 is peeled off by the peeling mechanism 40 will be described with reference to FIG. That is, this figure corresponds to a partially enlarged view of the vicinity of the flap portion in FIG. 3, the claw portion 5 is engaged with the root position of the flap 2, the flap inner surface support portion 6 is in contact with the peeling tape 3, In this state, ambient air is sucked from the suction port 7. Therefore, the right end of the release tape 3 on the paper surface is bent downward, and a deformation is induced so that the tip of the claw portion 5 can easily enter the gap.

Then, the conveyance is resumed to shift to FIG. 4, and as the envelope 1 is moved to the right side of the page, the claw portion 5 enters the back side of the release tape 3, and the release tape 3 moves along with the entry. The peeling tape 3 is sucked and removed along with the suction action of the air inlet 7 while extending over the whole. This situation can be easily understood from FIG. 7 showing the envelope 1 in the direction of conveyance downward. In other words, it is shown from the perspective of looking down at envelope 1, but from three places in the width direction of flap part 2, it engages with release tape 3 stuck on glue part 4 with nail part 5, and simultaneously Then, peel off the entire peeling tape 3 along with the transportation. The claw portions 5 are formed at a plurality of positions with an interval of approximately 15 to 100 countries, preferably 25 to 60 countries, and are formed in a well-balanced manner according to the envelope width.

Next, the restriction plate 14 shown in FIGS. 1 to 5 will be described.

As described above, this member operates at the same timing as the peeling mechanism 40. However, as shown in the enlarged view in FIG. 12, the peeling tape 3 is positioned near the cutting edge of the claw portion 5 during peeling. Then, free deformation such as fluttering that occurs when the flap part 2 is conveyed at the tip part thereof is restricted. Accordingly, the position is adjusted so that the flap portion 2 smoothly exits the gap with a certain interval without being caught between the blade edges of the claw portion 5.

[0029] And even if it comes in a state with some deformation due to the thin film, there is an effect of adjusting the engagement with the claw portion 5, and it can be added in practice to stably carry out the present invention. desirable. Further, the position of the front end portion of the restricting plate 14 is not limited to the position directly above the claw portion 5, and may be a position slightly back and forth in the transport direction from the blade edge. Specifically, it may be located within a range of about ± 5 countries.

In some cases, a good peeling state can be maintained without the restriction plate 14 being provided. If the shape of the claw part 5, the width of the air inlet 7, the negative pressure near the air inlet 7, and the film rigidity of the flap part 2 are matched well, it is possible to eliminate the unstable instability that easily occurs during transportation. It is. Of course, it would be unstable for a torso-type envelope. Compared with the flap part, the engagement of the peeling mechanism 40 is stable, and such a restriction plate can be omitted.

[0030] Next, a bending adhesion mechanism in the flap adhesion stage will be described with reference to Figs.

In FIG. 1, 1 b in the figure indicates an envelope, and shows the process of being peeled and removed from the peeling tape 3 at the tape peeling stage and transported to the next flap bonding stage. Reference numeral 1a denotes an envelope that precedes it, and shows a rear portion that is being discharged after the flap bonding stage has been folded and bonded to the flap portion.

[0031] FIG. 2 illustrates a state immediately before the envelope 1b is positioned and stopped by the stopper 37 on the flap bonding stage. That is, from the state shown in FIG. 1, the stopper 37 is lifted via the wrist stopper arm 38 due to the swinging motion of the arm fulcrum shaft 39, and is the state immediately before the bottom of the incoming envelope 1b is stopped. Note that the pinch roll 34 holding the envelope 1 b together with the conveying belt 31 is still in the position where the conveyance is maintained at this time, but when the bottom of the envelope 1 b comes into contact with the stopper 37 and stops. Needless to say, the arm fulcrum shaft 36 is displaced upward via the roll arm 35 by the swing operation.

Next, as for FIG. 3, this figure shows that the envelope 1 b reaches the flap bonding stage, the positioning is stopped, and the pad 60 and the bending plate provided outside the flap of the envelope 1 b. 61 shows the state in which the action has started. That is, when the holder arm 63 is operated, the pad 60 and the curved plate 61 attached to the holder 62 are lowered, the pad 60 presses the outer surface of the flap around the envelope entrance, and the curved plate 61 is the flap part at the tip end portion. The flap is pushed and bent inwardly in contact with the root portion of the plate.

[0033] On the other hand, on the inner surface side of the flap of the envelope 1b, the folding plate 50 attached to the folding plate arm 51 is in a state immediately after starting the next operation. In other words, the state of stopping with the retracting table 52 is maintained until immediately before reaching FIG. 1 to this figure, but the front end of the flap pushed and bent by the bent plate 61 is lower than the front end of the folding plate 50 on the envelope side. Natsu From this point on, the folding plate 50 starts to be displaced in the right direction on the paper surface with the folding plate arm 51. In this state, the retracting table 52 supports the lower surface of the envelope 1b and sandwiches the periphery of the entrance of the envelope 1b with the pad 60 with an appropriate force.

[0034] Now, with respect to FIG. 4, this figure shows a state where the flap of the envelope 1b has been folded and adhered after the transition from the state of FIG. Specifically, the progress of the bending bonding mechanism according to the present application will be described with reference to FIGS. That is, while the folding plate 50 is displaced in the direction indicated by the arrow 70, the leading end 50a of the folding plate 50 approaches the leading end 52a of the retracting table 52 as shown in FIG. In other words, only the folding plate 50 is displaced until the gap between the two becomes an appropriate gap, and thereafter, as shown in FIG. Therefore, the flap portion 2 of the envelope 1b is bent and bonded while passing through the gap in the process from FIG. 13 to FIG. Although the gap is not less than the extent that the flap 2 of the envelope is not sandwiched, it need not be wider than necessary, and is preferably about 1 to 6 countries.

[0035] Further, when the flap portion 2 is folded and bonded, the main body that supports the envelope 1b that has been pressed by the pad 60 from the lower surface gradually moves from the evacuation table 52 to the folding plate 50. To do. As a result, as is clear from FIG. 14, the folded-in plate 50 presses the attachment portion of the envelope flap portion 2 with an appropriate strength, and the adhesion can be ensured. The pad 60 is made of a relatively soft elastic material, and is made of an elastic material such as a rubber sponge having a large friction coefficient because the folding plate 50 and the retracting table 52 slide on the lower surface of the envelope. Is desirable. By doing so, when moving from the evacuation table 52 to the folding plate 50, even if there are some gaps or steps between the tip portions of both, it is possible to move while smoothly following.

Next, FIG. 5 will be described.

This figure shows a state in which the envelope 1b is being carried out from the flap bonding station after the folding bonding of the flap portion is completed. That is, the stopper 37 is released from the stopped state, and the pinch roll 34 is lowered to resume the conveyance of the envelope 1b. During this time, the folding plate arm 51 and the table arm 53 are Then, the folding plate 50 and the retracting table 52 are returned to their original positions, and similarly, the pad 60 and the bending plate 61 attached to the holder 62 are returned to their original positions by the displacement of the holder arm 63. The original position refers to the position shown in FIG.

[0037] The details of the flap bonding station have been described above with reference to Figs. From the state of FIG. 5 onwards, it goes without saying that the state of FIG. 1 is reached again, and envelopes that arrive one after another are used to perform the sealing process.

Further, in the illustrated embodiment, the means for stopping the envelope, the means for positioning, the means for resuming conveyance, the timing for activating these means, etc. are limited to those illustrated. It can be changed without any change.

Similarly, the design change of each member in the illustrated peeling mechanism 40, the design change of each member in the bending adhesion mechanism, the change of the displacement trajectory and the change of the operation timing are also limited to those illustrated. It can be changed without any change.

[0038] Further, regarding the relationship with the removal of the peeling tape at the tape peeling station described above, the illustrated embodiment apparatus is configured on a series of conveying paths with a predetermined distance therebetween. It is characteristic. And with that configuration, sealing can be completed in one step, and this kind of work can be mechanized at once.

The illustrated embodiment apparatus is a relatively short distance and is configured by associating both stations with a series of transport paths. However, an arbitrary distance can be set as necessary, such as by interposing another separate processing step. May be configured separately.

[0039] In addition, it is possible to provide an apparatus that is implemented as an independent process, if necessary, without linking each of them. For example, an apparatus in which only the tape peeling station is configured as described above, or an apparatus in which only the flap bonding station is described above.
