According to the above processing apparatus, when the feeding of the packaging material is temporarily stopped , the perforation is formed on the packaging material.
Make the cutting edge cut into the packaging to make it. At this time, Guy
Is located at the downstream position and is
An initial value is given to the clearance angle of the packaging material formed by the blade. After this, the guide member moves closer to the perforated cutter side from the downstream position.
Moved to the position to increase the clearance angle of the packaging material, and this clearance angle
And the cutting edge angle of the cutting edge is greater than 180 °. This
In this state, when the packaging material is fed out, the guide member guides the packaging material in the direction of pulling the packaging material away from the cutting edge, so that the packaging material can be naturally detached from the cutting edge as the packaging material is fed out.

Next, when the packaging material is extruded , the guide member is moved from the adjacent position to the downstream position and retracted from the perforation cutter, so that the formation of perforations by the pressing means is not hindered. .

The above-mentioned pressing means may include a pressing roller which is movable in the transverse direction along the supply path, and the pressing roller partially receives the cutting edge on the outer peripheral surface in the movement process thereof. Roll on the cutting edge through the packaging material (claim 2 ). In this case, since the member to be moved is only the pressing roller, it is possible to easily realize high-speed operation of the processing device.

When the product stack Ts is at the same level as the packaging line 4 due to the rise of, the pusher 18 moves forward to move the product stack Ts.
Is pushed toward the packaging line 4. Such a forward movement of the pusher 18 pushes the product aggregate Ts on the elevator 16 together with the parcel sheet S to the complete folding position in the packaging line 4. Due to this pushing, as is known, the parcel sheet S is made U by the product aggregate Ts.
It is folded into a letter shape.

Thereafter, as shown in the figure, the parcel sheet S is transferred in the process of transferring the product aggregate Ts in the packaging line 4.

In the packaging process shown in FIG. 1, the perforation processing apparatus 20 of the embodiment is arranged in the middle of the parcel paper P supply line 6, and the perforation processing apparatus 2 is used.
Details of 0 are shown in FIGS. FIG. 2 shows the internal configuration of the perforation processing device 20 as seen in the payout direction of the parcel paper P shown by the arrow in FIG. 1, and FIG. 3 shows a vertical cross section as seen in the width direction. Has been done.

2 and 3, the perforation processing apparatus 20 has a casing 22. The casing 22 has openings 24 and 26 in the front and rear walls as viewed in the feeding direction of the parcel paper P. Have As shown in FIG. 3, the parcel paper P passes through the inside of the casing 22 through the openings 24 and 26 and is fed out along the supply line 6.

The perforation processing device 20 is provided with a pair of front and rear lower guides 28, 30 (guide members) formed of guide plates. Parcel paper P in casing 22
The lower guides 28 and 30 guide the feeding of the paper, and both the lower guides 28 and 30 guide one surface (the lower surface in FIG. 3) of the parcel paper P by their guide surfaces. More specifically, the guide surfaces of the lower guides 28 and 30 are
Each of the parcel sheets P extends horizontally from the openings 24 and 26 toward the inside of the casing 22.
Between 8 and 30, it is held in a flat shape as shown.

The tips of the lower guides 28 and 30 are bent downward with respect to the parcel sheet P, and these tips are separated from each other in the feeding direction of the parcel sheet P with a predetermined interval therebetween. Further, the casing 22 corresponds to the front and rear lower guides 28 and 30, respectively.
2, 34 are attached. These upper guides 3
Reference numerals 2 and 34 guide the smooth movement of the parcel paper P into and out of the openings 24 and 26, respectively.

Between the lower guides 28 and 30 described above,
A perforation cutter 36 is arranged, and the perforation cutter 36 extends in the transverse direction along the supply line 6. The perforation cutter 36 is at the upper edge,
A cutter region for perforation processing, that is, a cutting edge 38 is provided at the center thereof. The cutting edge 38 is formed below the parcel paper P so as to be spaced apart therefrom and to face the lower surface thereof.

Further, both ends of the perforated cutter 36 extend to both sides of the parcel paper P, and the both ends are suspended from the lateral wall 42 of the casing 22 via springs 40, respectively. It should be noted that pins 44 and 46 for hooking the spring 40 are respectively provided on both ends of the perforated cutter 36 and the left and right lateral walls 42 so as to project. The spring 40 is composed of a tension coil spring, and biases the perforated cutter 36 upward, that is, toward the parcel paper P in the illustrated state.

The perforation processing apparatus 20 includes a casing 22.
A reciprocating drive belt 48 composed of a timing belt is provided therein, and the reciprocating drive belt 48 is arranged such that its traveling direction is the width direction of the parcel paper P, that is, the transverse direction of the supply line 6. The reciprocating drive belt 48 is wound around a pair of left and right toothed pulleys 50 and 52, and these toothed pulleys 50 and 52 are separated from each other in the left and right direction beyond the width of the parcel sheet P. One toothed pulley 50
Is a drive pulley, and this toothed pulley 50 is attached to the output shaft of a servo motor (not shown). In addition,
The body of the servomotor is projected outside the casing 22.

A slider 54 is attached to the reciprocating drive belt 48, and the slider 54 can move as the reciprocating drive belt 48 travels. Further, the rear wall of the casing 22 is supported by a guide rail 56 , and the guide rail 56 extends parallel to the supply line 6 and in the transverse direction thereof. The guide rail 56 guides the movement of the slider 54 and keeps the movement direction parallel to the supply line 6.

Further, the slider 54 is provided with a pressing roller 58, the outer peripheral surface of which is brought into contact with the upper edge of the perforated cutter 36. The pressing roller 58 can move in the transverse direction of the supply line 6 as the slider 54 moves. As described above, since the perforation cutter 36 is biased upward, the pressing roller 58 moves in the course of its movement, and the perforation cutter 36 is urged.
Roll on the upper edge of.

Of the lower guides 28 and 30 described above, the lower guide 30 on the downstream side in the feeding direction is the casing 2
It is attached so as to be movable with respect to 2. More specifically, the opening 26 of the casing 22 is sized to receive the lower guide 30 including the base end thereof, so that the lower guide 30 passes through this opening 26.
It is possible to further enter the casing 22 from the position shown in FIG.

As a driving means for moving the lower guide 30, for example, a direct acting type air cylinder 60 can be used, and as shown in FIG.
The air cylinder 60 is arranged in a horizontal posture. The end plate of the air cylinder 60 is connected to the base end portion of the lower guide 30, and the air cylinder 60 can drive the lower guide 30 to reciprocate in the direction of the arrow in the figure. In addition, for example, the air cylinders 60 are attached to the casing 22 through the brackets 62, and a plurality of air cylinders 60 are arranged with respect to the lower guide 30 at intervals in the longitudinal direction thereof.

The slider 54 can stop its movement at the left and right rest positions, and in this state, the pressing roller 58
Is located outside the parcel paper P with respect to the supply line 6. Further, the feeding of the parcel paper P by the feed roller 8 described above is executed in a state in which the pressing roller 58 is located at the left or right rest position. When the feeding of the parcel paper P is temporarily stopped according to a predetermined operation cycle during the operation of the packaging machine, the slider 54 moves from one rest position to the other. At this time, the pressing roller 58 rolls on the cutting edge 38 via the parcel paper P to form perforations on the parcel paper P.

Referring to FIG. 4, the pressing roller 5 described above is used.
The formation of perforations by No. 8 is shown in more detail. That is, the outer peripheral surface of the pressing roller 58 partially covers the cutting edge 38.
To be able to accept add, therefore, the individual cutting edge 38 with the rolling of the pressing roller 58 can be sequentially retracts only the pressure roller 58 a predetermined depth. At this time, the pressing roller 58 presses the parcel paper P downward by its outer peripheral surface , that is, by pushing down the parcel paper P, the individual cutting edges 38.
Relatively penetrates into the parcel paper P, and the parcel paper P has a length corresponding to the cutter area in a broken hole, that is,
Perforations are formed.

Next, with reference to FIGS. 5 and 6, the separation of the parcel paper P after the perforation processing and the cutting edge 38 will be described in detail. As shown in FIG. 5, parcel paper P depressed et a by the pressing roller 58 is deformed from its original planar shape (two-dot chain line in the drawing), so bite blade 38 cutting against the deformed portion It is in a broken state. Here, the cutting edge 38 has a predetermined cutting edge angle α (for example, 45 ° to 90 °).
In the illustrated state, the cutting edge 38 has a predetermined clearance angle β ₀ (about 80 ° to 50 °) with respect to the parcel paper P.

On the other hand, when the perforation processing is completed, the lower guide 30 is moved by driving the air cylinder 60, and the lower guide 30 is moved to the perforated cutter 3 as shown in FIG.
Proximity to 6. In the state shown in FIG. 6, the parcel paper P is extremely greatly warped upward between the lower guide 30 and the perforated cutter 36. When the parcel sheet P is fed out in this state, the lower guide 30 guides the parcel sheet P in the direction away from the cutting edge 38, as shown by the arrow in the figure. Therefore, the parcel paper P can be smoothly detached from the cutting edge 38 as shown by the chain double-dashed line in the figure with this feeding.

More specifically, the clearance angle β ₁ of the cutting edge 38 on the lower guide 30 side is larger than the initial clearance angle β ₀ shown in FIG. 5 because the lower guide 30 is close to the perforated cutter 36. Is understood. As a result of paying attention to the relationship between the clearance angle β ₁ and the separation characteristics of the parcel paper P, the inventors of the present invention find that in order to obtain smooth separation of the parcel paper P, the clearance angle β ₁ and the cutting edge angle α Japanese is flat (180
It has been confirmed that it is effective to set the value so that it exceeds (°).

Specifically, as shown in FIG. 6, when the lower guide 30 is brought close to the perforated cutter 36, a plane including a flank of the cutting edge 38 on the lower guide 28 side (X in the figure).
It is preferable to bring the lower guide 30 close to a position where the parcel paper P is peeled above the −X plane). Even if the parcel paper P is fed out in the state of FIG. 6, the parcel paper P is guided so as to be lifted above the plane XX, so that the cutting edge 38 is not caught by the parcel paper P. The parcel paper P has a cutting edge 3
When separated from 8, the lower guide 30 is returned to the initial position shown in FIG. 5 by the operation of the air cylinder 60 and separated from the perforated cutter 36.

After that, when the feeding of the parcel paper P is stopped in the next operation cycle, the pressing roller 58 starts its movement again to form new perforations on the parcel paper P. Here, referring to FIG. 7, a relative positional relationship between the perforation processing apparatus 20 and the packaging line 4 in the integrated packaging machine is shown as a model. In the figure, assuming that the length of each parcel sheet S is L ₁ , the above-described registration marks are printed on the parcel paper P at a pitch of this length L ₁ .

Since the perforation processing apparatus 20 operates to perform perforation processing every time the feeding of the parcel paper P is stopped, the perforation M is also added at the pitch of the length L ₁ . Here, in terms of the actual length of the parcel paper P on the supply line 6, the distance L ₂ between the perforation processing device 20 and the cutter unit 12 is such that the perforation M is located near the center of the parcel sheet S as shown in the figure. It is properly set to do so. Therefore, the parcel paper P has perforations M for each region of the parcel sheet S to be formed by the cutting.
Is processed.

Referring to FIG. 8, the formed parcel sheet S is specifically shown. As shown in the figure, each parcel sheet S is provided with perforations M extending in the width direction, and the length L ₄ of the perforations M is the same as that of the blade 38 of the cutting edge 38 as described above. It is set to be slightly shorter than the width of the entire aggregate Ts. Further, the supply position of the parcel sheet S by the suction belt 14 is shown in FIG.
As shown in, the perforation M is set to be located above the reference plane of the packaging line 4 by the height H of the cigarette pack T. That is, in terms of the actual length of the parcel paper P on the supply line 6, the distance L ₃ between the reference surface of the packaging line 4 and the perforation processing device 20 has a height H that is a multiple of L _1. It is set to the added length.

Therefore, when the product stack Ts is pushed into the parcel sheet S in the state shown in FIG. 7, the perforation M of the parcel sheet S is positioned between the stacking stages of the cigarette pack T when the body folding is completed. Positioned. Further, as apparent from FIG. 8, at this time, the product aggregate T
s is positioned in the center in advance when viewed in the width direction of the parcel sheet S.

Referring to FIG. 9, in the completed parcel packaged product PC (with no brand label or the like attached), perforations M are positioned between the stacking stages of the packaged cigarette packs T. The joint of the body flap is located on the opposite side of the perforation M as seen in FIG. The perforation M attached by the perforation processing apparatus 20 of the above-described embodiment is, for example, perforation M.
Pitch of 6 mm (open hole length 4.5 mm, unopened hole length 1.5 mm)
Is set to.

Further, the inventors of the present invention conducted a tensile test on the parcel paper P having perforations M to confirm the tensile strength. According to the observation of the inventors, rather than performing perforation processing along the fiber direction of the parcel paper P (longitudinal),
Perforation processing is performed in the direction orthogonal to the fiber direction (side grain)
It has been confirmed that the tensile strength of the parcel paper P is higher. In any case, the strength level of the parcel sheet S is sufficiently secured in handling the cigarette product in the distribution process, and the parcel sheet S is not undesirably torn in the distribution process.

Perforation processing apparatus 20 of the above-described embodiment
Does not require a special process for separating the parcel paper P and the cutting edge 38 after perforating the parcel paper P. That is, since the parcel paper P can be detached from the cutting edge 38 as it is fed out, without waiting for the completion of the separation work by the perforation processing device 20,
The parcel paper P can be immediately fed out after the perforation processing.

Further, the perforation processing apparatus 20 only moves the pressing roller 58 including the slider 54 during its operation, and the inertial mass of the movable portion of the apparatus can be suppressed small. Therefore, by shortening the time required to move and stop the pressing roller 58, it is possible to cope with the high-speed operation of the apparatus and also contribute to the shortening of the packaging cycle time of the entire integrated packaging machine.

The present invention can be variously modified and implemented without being limited to the above-described embodiment. In the embodiment described above, only the lower guide 30 on the downstream side is moved, but both lower guides 28, 30 may be moved. As the means for moving the lower guides 28, 30 and the like, in addition to the air cylinder 60 of the embodiment, a reciprocating slider mechanism, a reciprocating belt mechanism or the like can be appropriately used.

Further, the guide member in the present invention is not limited to the guide plates such as the lower guides 28 and 30,
It can be replaced with a guide roller or a guide rod.
In the above embodiment, the lower guide 30 is entirely moved, but the main body of the lower guide 30 may be used as a fixed guide, and the movable guide plate may be extended from the lower guide 30 toward the perforated cutter 36.

When a guide roller or a guide rod is applied as the guide member, not only the guide roller and the guide rod are moved horizontally along the packaging line 6, but the guide member may be brought close to the perforated cutter 36 by its swinging, for example. . Even in this case, the clearance angle β ₁ and the cutting edge angle α shown in FIG.
The relationship with is properly maintained. On the other hand, it is also possible to use the lower guide 30 simply as a fixed guide without disposing the air cylinder 60. In this case, a sufficient clearance is secured between the lower guide 30 and the pressing roller 58. However, even in this case, it goes without saying that the sum of the cutting edge angle α of the cutting edge 38 and the clearance angle β ₁ is set to exceed 180 °.

Further, although the pressing roller 58 is used for pressing the parcel paper P in the above-mentioned embodiment, for example, as the pressing means, a pressing member (press bar having a pressing surface extending in the width direction of the parcel paper P is used. ) Can also be used. This pressing surface may be flat or may be warped with respect to the parcel paper P. In these cases, the planar pressing surface temporarily presses the parcel paper P against the cutting edge 38, while the warped pressing surface can apply pressing force to the parcel paper P while rolling.

Further, in the case of the present invention, when the length of perforation to be machined is changed, the perforation cutter 36 is changed to
It is only necessary to replace it with another perforated cutter having a different blade crossing of the cutting edge 38. In this respect, in the known device described above, the work load is heavy because the entire moving unit including the gear and the perforated disc must be replaced.

In the above-described embodiment, one perforation M is provided for each parcel sheet S. However, for example, the perforation processing apparatus 20 of the embodiment is arranged at a plurality of locations on the supply line 6, or By arranging a plurality of perforation cutters 36 in the perforation processing device 20, a plurality of perforations M can be attached to one parcel sheet S. Furthermore,
By changing the setting of the intervals L ₂ and L ₃ in FIG. 7, the position of the perforation M can be changed as desired in the parcel packaged product PC.

In addition, for example, an operation changeover switch can be connected to the perforation processing apparatus 20, and either operation or stop can be selected as required. Further, it goes without saying that the processing apparatus of the present invention is not limited to parcel paper and is suitable for perforation processing of packaging films, package blanks and the like, and can be widely applied to other than the packaging machine for cigarette packs.

As described above , according to the packaging material processing apparatus of the present invention (claim 1), the downstream position and the perforation
The guide member that can reciprocate between the
Since it is equipped, the guide part
By positioning the timber in proximity position, the packaging material can in disengaged from the cutting edge with their feed, amount that does not require the separation work of the packaging material and the cutter, it is possible to advance the feeding start timing of the packaging material. Therefore, shortening of the operation cycle in the packaging machine is not hindered.

When processing perforations, the guide member is
Since it is located downstream from the perforation cutter, it is possible to perform perforation processing with higher quality. Further, if the movable member for perforation processing is a pressing roller (claim
2 ) Its inertial mass is small, and it is easy to speed up the operation. Therefore, for example, in a cigarette manufacturing factory, the operating speed of the packaging machine can be increased in synchronization with the high-speed operation of the cigarette manufacturing machine, and the operating rate of the entire factory can be greatly improved.
