As described above, in the conventional splicer device, since the original fabric support shaft is installed above the device, the original fabric roll must be mounted on the original fabric support shaft in a state of being lifted upward. Attaching and detaching work to and from the shaft is complicated and labor intensive.

During operation, the operator must pull the leading end of the other raw roll on standby along a predetermined path and insert and set it into the film splicing device from above. In particular, in the work of supplying and setting the leading edge of the film in the film splicing device so that it hangs down from above, the other film in operation is moving in the immediate vicinity, and for example, the operator may accidentally touch the film. It is not desirable because there is a risk.

After passing through the film splicing device, the film moves in the limited narrow lower space and is supplied to the packaging machine main body. Even if there is such a request, it is not possible to install devices and equipment for performing these processes. Therefore, in order to carry out these processes, it is necessary to once pull out the film outside the splicer device and carry out the relevant processing with devices/equipment arranged outside the splicer device. Therefore, a large space is required to install the splicer device/packaging machine.

The above-described problems are described as independent ones, and the present invention does not necessarily have to be able to solve all of the described problems, and it is sufficient if at least one of the problems can be solved. In addition, we intend to obtain the right for the configuration to solve this problem by filing a divisional application or making an amendment.

In order to perform continuous supply by bonding such films, the worker sets the original roll on standby to the original roll support portion at an appropriate timing while the packaging film is being supplied during operation, or sets it to the original roll. A packaging film fed from a raw roll is set in a film setting device.

In the present invention, a film splicing device is provided in the middle of the transport path for flowing the packaging film from bottom to top. Since the material is supplied from the bottom to the top in this way, the installation position of the original fabric support shaft can be set at a position lower than that of the conventional one, and it can be placed at a position that is ergonomically easy to set. . In addition, since the film setting device is arranged at a low position such as below the film splicing device, the operation of setting the film on the table member can also be performed at the low position, thereby improving workability.

The operation of setting the packaging film on the film setting device is performed on the table member in the first posture. The table member in the first posture is laid down and separated from the transportation path of the packaging film during operation, and a suitable space can be secured above and around the table member. Therefore, for example, when the tip portion of the film is arranged on the adsorption surface of the table member, the possibility of accidentally contacting the packaging film or the like that is moving during operation can be suppressed as much as possible, and safety is improved. increases.

The waiting packaging film set at a predetermined position on the table member is held by suction on the table member. When bonding the packaging film in operation, the table member stands up and is displaced to the second posture. The packaging film also stands up and its leading edge is close to the transportation path of the packaging film during operation. Then, at an appropriate timing, the film splicing device splices the packaging film in operation and the packaging film on standby. Thereafter, the packaging film on standby is transported together with the packaging film in operation and supplied to the main body of the packaging machine. In this way, after the leading end portion of the packaging film is set on the table member, the splicer device can perform the splicing process at an appropriate timing, and the worker does not have to reach out after setting the film, which is safe.

Place a drive system that gives The devices that make up the transfer system are mounted on the front side of the mounting base plate 11 with a cantilever support structure, as shown in FIG. 3 and subsequent figures, for example. Specifically, it is configured as follows.

A first fabric support shaft 12 and a second fabric support shaft 13 are rotatably arranged at predetermined positions of the mounting base plate 11 via bearing portions. This predetermined position is the midpoint in the vertical direction, and is positioned at the same height with a predetermined distance in front and rear along the transport direction of the horizontal pillow packaging machine 1 . The first fabric support shaft 12 and the second fabric support shaft 13 are arranged in parallel. A first film roll 14 obtained by winding a band-shaped packaging film 14a into a roll is detachably attached to the first film support shaft 12 . A second film roll 15 obtained by winding a band-shaped packaging film 15 a into a roll is detachably attached to the second film support shaft 13 . The first roll 14 and the second roll 15 rotate integrally with the first support shaft 12 and the second support shaft 13, respectively, when attached to the support shafts.

In the state in which the new first roll 14 and the second roll 15 are mounted, the lower side of the outer peripheral edge of the first roll 14 and the second roll 15 is the product conveying position positioned below. It is set so as to come to a position close to the supply conveyor device 3. In the conventional splicer device, a bearing is supported at a relatively upper position of the mounting base plate 11, or an arm extending upward from the upper position is attached, and the original fabric support shaft is attached to the tip of the arm. In this embodiment, the original fabric supporting shaft is arranged at a low position. In the illustrated example, the packaging film 14a unwound from the first film roll 14 mounted on the first film support shaft 12 is being supplied to the packaging machine main body 2, and the second film roll 15 is in operation. Waiting. When the packaging film 14a from the first film roll 14 runs out and the packaging film 15a of the second film roll 15 joined to the packaging film 14a is supplied to the packaging machine main body 2, the second film roll The second web support shaft 13 is in operation, and the first web roll 14 and first web support shaft 12 are on standby.

In this embodiment, the first web support shaft 12 and the second web support shaft 13 are driven by a drive motor (not shown) (for example, a speed controllable motor such as a servomotor) arranged on the opposite side of the mounting base plate 11 . , and the packaging films 14a and 15a are sent out at a constant speed while appropriately controlling the rotation speed of the first film roll 14 or the second film roll 15.

Further, on the mounting base plate 11, a plurality of rollers 17 are directly mounted or a predetermined connection plate or the like is attached to predetermined positions on the same front side surface on which the first fabric support shaft 12 and the second fabric support shaft 13 are cantilevered. to be rotatable through The packaging films 14a and 15a continuously fed out from the first film support shaft 12 or the second film support shaft 13 are appropriately stretched over a plurality of rollers 17 or the like and transferred along a predetermined transfer route, and then transferred to the downstream side. It is guided to the main body 2 of the packaging machine. A predetermined roller 17a of the plurality of rollers 17 is bearing-supported via a moving device 16, and is driven by the moving device 16 so as to be reciprocally movable in the horizontal direction. By reciprocating the rollers 17a in the horizontal direction, the packaging films 14a and 15a being conveyed are not loosened or excessively tensioned, and a constant tension is applied to the packaging films 14a and 15a. Control.

In the middle of the transportation path of the packaging films 14a, 15a, the leading end portions of the packaging film being operated/supplied (the packaging film 14a in the illustrated example) and the waiting packaging film (the packaging film 15a in the illustrated example) are joined. A film splicing device 20 is arranged. The film splicing device 20 is arranged in a cantilevered manner at the central portion above the front side surface of the mounting base plate 11 .

Based on this film bonding device 20, two regions (first region R1 and second region R2) are divided into left and right (front and back along the conveying direction of the horizontal pillow packaging machine 1). In the first region R1, there are rollers 17, 17a on which the first film support shaft 12 and the packaging film 14a unwound from the first film roll 14 are passed, and the first film on which the leading edge of the film is set during standby. The setting device 21 and the like are arranged. On the other hand, in the second area R2 on the right side as viewed from the front side, there are rollers 17, 17a for passing the packaging film 15a unwound from the second film support shaft 13 and the second film roll 15, and a standby A second film setting device 22 or the like for setting the leading edge of the film is arranged. The second region R2 is located on the packaging machine main body 2 side, and the packaging films 14a and 15a moving downstream of the film splicing device 20 move within the second region R2, It is configured to reach the carry-in port.

Furthermore, a partition wall 23 is arranged below the film splicing device 20 . The partition wall 23 has a substantially flat plate shape and is perpendicular to the mounting base plate 11, and is arranged on the boundary surface between the first region R1 and the second region R2 within a vertical plane. The partition wall 23 is sandwiched from both sides by a support member 24 mounted in a cantilever manner on the front side of the mounting base plate 11, and is configured to hold the predetermined posture and position. Further, the supporting member 24 is supported and fixed by dividing a cylindrical body in half and sandwiching it between semi-cylindrical members. By doing so, the connecting surfaces at the boundary line between the support member 24 and the partition wall 23 are connected smoothly, so that the boundary line portion is less likely to be contaminated with dust.

The first film setting device 21 and the second film setting device 22 are both of the same construction, and consist of a base member 25 arranged in a cantilever manner on the mounting base plate 11 so as to extend in the horizontal direction, and the base member 25. A table member 26 and a cutter device 27 are provided at the end on the partition wall 23 side so as to be rotatable within a predetermined angular range.

The basic configuration of the base member 25 includes a plurality of free rollers 28 rotatably linked to the mounting base plate 11 at their proximal ends, and side walls 29 rotatably supporting the distal ends of the free rollers 28 . do. That is, both ends of the plurality of free rollers 28 arranged in parallel are supported by the bearing portions provided on the side wall 29 and the mounting base plate 11, respectively, so that the plurality of free rollers 28 are integrated and can assume a desired posture. is cantilevered with respect to the mounting base plate 11 at . The packaging films 14a and 15a are stretched over the plurality of free rollers 28, forming part of the transport path.

The table member 26 is connected to the end portion of the side wall 29 on the partition wall 23 side and the connection plate 31 attached near both ends of the rotation shaft 30 supported by the bearing portion provided on the mounting base plate 11 . forward and reverse rotation within a predetermined angle range. Further, in this embodiment, the rotating shaft 30 and one free roller 28 are arranged coaxially, and the rotating shaft 30 and the free roller 28 are linked so as to be rotatable independently of each other. As a result, for example, the free roller 28 is allowed to rotate while the rotary shaft 30 is stopped, or the rotary shaft 30 can rotate forward and backward while the free roller 28 is stopped. The end of the rotating shaft 30 on the side of the mounting base plate 11 passes through the mounting base plate 11 and is located on the far side, is linked to a driving means such as a motor or a cylinder, receives an output from the driving means, and rotates within a predetermined angle range. It is configured so that it rotates forward and backward inside.

As a result of this forward and reverse rotation, the table member 26 falls in a first posture in which the leading end is tilted away from the partition wall 23 as shown in FIG. , and transitions between the second posture in which the tip is tilted forward so that the tip approaches the partition wall 23 .

The table member 26 has a concave cut portion 26a at its tip, and has a comb tooth-like planar tip having a ridge portion 26b between the adjacent concave cut portions 26a. The table member 26 is formed of a flat box, and has a large number of suction ports 26c at predetermined positions on its surface. etc., sucking from the suction port 26c, for example, when the packaging film is placed on the surface of the table member 26 so as to cover the suction port 26c, the packaging film is sucked and held. The suction port 26c is also formed in the ridge portion 26b. As a result, for example, when the leading end portions of the packaging films 14a and 15a are aligned with the leading end portion of the table member 26 and arranged to face the recessed cut portion 26a and the ridge portion 26b, the packaging films 14a and 15a are arranged to face the ridge portion 26b. It is also sucked from the suction port provided at the bottom, and is sucked and held while facing the recessed cut portion 26a.

Furthermore, in this embodiment, the suction paths for the plurality of suction ports 26c are divided for each arrangement area, and the suction ports 26c that perform the suction operation can be selected. In this embodiment, it is divided into three areas: a central area in the width direction along the direction of arrangement of the rotating shaft 30, an extended area including the central area and extending outward, and an entire area including all the suction ports 26c. A manual or automatic switching valve is provided in the middle of the suction path, and by operating the switching valve, the suction operation can be performed from the suction port 26c belonging to the selected area. As a result, in the case of a film having a narrow width, for example, either the central area or the extended area operates according to the width of the film, so that the suction ports 26c for the suction operation of the packaging films 14a and 15a are all covered and reliably sucked. In addition, in the case of a film having a wide film width, the packaging films 14a and 15a can be sucked and held over the entire film width direction.

The cutter device 27 includes a rotary cutter, a driving mechanism for rotating the rotary cutter, and the like in a rectangular case 27a. Although not shown, the rotary cutter employs a rotary type in which a cutting blade and a receiving blade rotate in opposite directions to cut the packaging film sandwiched between the two blades. As a result, the packaging films 14a and 15a arranged to pass through the cutter device 27 are cut by the rotary cutter moving in the film width direction, that is, in the direction perpendicular to the film transfer direction, and cut back and forth. fragmented.

The film splicing device 20 has a transport path for moving the packaging films 14a and 15a from bottom to top, and is provided with a pair of press rollers 33 arranged above the transport path so as to sandwich the transport path. The pair of press rollers 33 are mounted on a drive shaft 38 bearing-supported by a pair of arm members 37 connected to both ends of a rotation support shaft 35 . The press roller 33 uses a plurality of narrow roller elements 33 a , and the plurality of roller elements 33 a are arranged along the axial direction of the drive shaft 38 . Each roller element 33a has a roller width along the axial direction that is substantially equal to or slightly shorter than the opening width of the recessed cut portions 26a, and the arrangement pitch of each roller element 33a matches the arrangement pitch of the recessed cut portions 26a. Let

One end of the rotation support shaft 35 located on the back side is located on the back side of the mounting base plate 11, and cooperates with a driving device such as a motor or a cylinder disposed on the back side of the mounting base plate 11 to rotate at a predetermined angle. Forward and reverse rotation within the range. Along with this, the pair of press rollers 33 suspended and supported by the arm member 37 and the drive shaft 38 rotate forward and reverse within a predetermined angular range about the rotation support shaft 35 to approach and separate from each other. The pair of press rollers 33 are separated from each other in an open standby state (see FIG. 7(a), etc.), and in a state in which both roller elements 33a are closed and opposed to each other in a substantially vertical direction, either directly or indirectly with the packaging film interposed therebetween. It transitions between pressurized states (see FIG. 7(b), etc.) in which the contact surfaces are in contact with each other.

When the pair of press rollers 33 are in the open standby state, the height of the press rollers 33 is set to be higher than in the contact state. As a result, when the pair of press rollers 33 are in the standby state as shown in FIG. 7A, the table member 26 interferes with the press rollers 33 and is allowed to rotate forward and backward. It is possible to get up from and transition to the second posture.

Further, for example, when the press roller 33 transitions from the standby state to the contact state while the table member 26 is in the second posture, each roller element 33a that constitutes the press roller 33 enters the concave cut portion 26a of the table member 26. , pressurized with a predetermined pressure. Therefore, when the film portions of the packaging films 14a and 15a are present in the recessed cut portion 26a, the film portions are sandwiched from both sides and pressed with a predetermined pressure.

The drive shaft 38 receives power from a drive source such as a drive motor (not shown) and rotates at a predetermined speed. The predetermined speed is such that the peripheral speed of the surface of the roller element 33a is equal to the phase speed of the packaging films 14a and 15a. Thereby, the contact resistance is suppressed as much as possible with respect to the packaging films 14a and 15a that come into contact under pressure. For example, if the press roller 33 is a free roller and is configured to rotate following the movement of the sandwiched packaging films 14a and 15a, this may act as resistance and delay film feeding. On the other hand, in this embodiment, the press roller 33 is rotated at the same speed as the packaging films 14a and 15a so as not to generate resistance, thereby solving the above problem. In particular, in the configuration in which the packaging film is fed out at high speed in addition to flowing from bottom to top as in the present embodiment, the resistance when used as a free roller increases, so it is more preferable to adopt the configuration of this embodiment.

In this embodiment, as shown in FIGS. 1 and 2, the splicer device 10 is configured such that the entire space on the front side of the mounting base plate 11 is covered with the cover member 40 . The cover member 40 connects the rear edge of the top panel 40 a to the mounting base plate 11 via a rotation support shaft 45 . As a result, the cover member 40 rotates forward and reverse within a predetermined angular range about the rotation support shaft 45, and the cover member 40 as a whole covers the splicer device 10 as shown in FIGS. and an open posture, although not shown, in which the front side of the cover member 40 is lifted upward to open the space on the front side of the mounting base plate 11 as a whole. During normal driving operation, the cover member 40 maintains the closed basic posture, so that accidental contact with the splicer device 10 during driving is suppressed as much as possible.

Furthermore, the cover member 40 of this embodiment has a first door portion 41 and a second door portion 42 on the front side.
The first door portion 41 is arranged to cover the front surface of the first region R1, and the second door portion 42 is arranged to cover the front surface of the second region R2. For the sake of convenience, the second door portion 42 is not shown in the drawing, and the inside is shown. Each door is attached to a predetermined position of the main body of the cover member 40 so as to be openable and closable independently of each other. In this embodiment, the first door portion 41 is connected via a hinge member 46 at the left side edge, and the second door portion 42 is connected via a hinge member 47 at the right side edge. As a result, the first door portion 41 and the second door portion 42 can be opened and closed like double doors. Furthermore, the first door portion 41 and the second door portion 42 link their respective opening/closing operations and interlocks. Specifically, when the first door portion 41 is opened, the mechanism for feeding out the first roll 14 such as the drive motor for driving the first roll 12 stops, but the second roll 13 is driven. The mechanism for feeding the second roll 15, such as a drive motor, is controlled so as not to stop, and when the second door part 42 is opened, the second roll 15, such as a drive motor, drives the second roll support shaft 13. The mechanism for feeding the roll 15 is stopped, but the mechanism for feeding the first roll 14 such as the drive motor for driving the first roll 12 is controlled so as not to stop.

As a result, as will be described later, even if the door on the standby side is opened in order to set the film of the original roll on standby, the supply of the packaging film from the original roll in operation continues. At the same time, the standby side can be interlocked to maintain the stopped state, so that the packaging film can be set safely. Since the area on the operating side is surrounded by the main body of the cover member 40, the door portion, and the partition wall 23, it is possible for a worker, etc., who performs the setting work, to accidentally touch the device/equipment in operation or the packaging film in motion. Minimize the risk of contact. In addition, when the door on the operating side is opened, an interlock is applied to stop unwinding and feeding of the packaging film, ensuring safety.

For example, the film joining process of the splicer device in the embodiment described above may be performed as follows. In the figure, the packaging film 14a unwound from the first film roll 14 in operation is guided by the rollers 17 installed in the first region R1, moves in the upper space in the first region R1, and then travels downward. to reach the first film setting device 21, and further guided by the free roller 28 of the first film setting device 21 to be transported toward the partition wall 23 side, and then change its course upward to the film splicing device 20, and after passing through the film splicing device 20, it moves in the upper space of the second region R2 and is supplied toward the main body of the packaging machine. When passing through the first film setting device 21, the packaging film is routed so as to pass through the cutter device 27 as well. During operation, the table member 26 assumes the first position, and the packaging film 14a reaches the film splicing device 20 without contacting the table member 26. As shown in FIG. By keeping the first door part 41 closed, the operation is continued and the packaging film 14a is continuously supplied to the packaging machine main body 2 .

In this state, for example, when the second roll 15 for standby is attached to the second roll supporting shaft 13, the second door portion 42 is opened. Even if the second door part 42 is opened, the rotation of the first film support shaft 12 does not stop, and the supply of the packaging film 14a to the packaging machine body 2 continues. In addition, since the drive system of the second area R2 is interlocked and stopped, the second roll 15 can be moved safely without the second roll supporting shaft 13 accidentally rotating. It can be attached to the raw fabric support shaft 13 . Furthermore, the second roll supporting shaft 13 is arranged at a relatively low position, so that the worker can set the second roll 15 without having to lift it particularly high, thus reducing the labor required for the setting work.

The worker passes the packaging film 15a from the waiting second roll 15 set on the second roll supporting shaft 13 to the rollers 17, 17a installed in the second region R2, and After moving in the upper space in the second area R2, the course is changed downward and set so as to reach the second film setting device 22. - 特許庁In the second film setting device 22, the packaging film 15a is stretched over the free roller 28 and moved along a predetermined path, and is set so as to pass through the cutter device 27 in the middle of the movement. It is brought into contact with the table member 26 in the first posture. At this time, the packaging film 15a is arranged so as to face the protrusion 26b. With this arrangement, the packaging film 15a is folded upward along the free rollers 28 arranged on the partition wall 23 side and arranged along the table member 26. closes the suction port 26c provided in the .

Therefore, when the suction pump is operated in this state, the leading end portion of the packaging film 15a is attracted and held by the table member 26 in a stretched state. In this adsorbed and held state, the vicinity of the leading end edge of the packaging film 15a consists of a film portion that faces the protrusion 26b and is adsorbed and held, and a state in which both front and back surfaces are exposed facing the concave cut portion 26a. There is a film portion. Also, the worker attaches a pressure-sensitive adhesive tape to the edge of the wrapping film 15a on standby. In this state, the system waits until the supply of the packaging film 14a unwound from the first film roll 14 in operation to the packaging machine main body 2 is nearly finished.

As is clear from the figure, the work of setting the waiting packaging film 15a on the table member 26 is performed on the table member 26 which is in the first posture and has a wide upper space. Devices and equipment for transporting the packaging film 14a unwound from the first roll 14 inside, and the risk of accidentally touching the packaging film 14a are eliminated as much as possible. Furthermore, in this embodiment, since the partition wall 23 is arranged between the first region R1 and the second region R2 to separate them, for example, when performing processing such as setting the packaging film in the second region R2, Accidental entry of the body into the first region R1 can be more reliably suppressed.

As described above, the table member 26 of the second film setting device 22 on which the waiting packaging film 15a is set transitions to the second position at a predetermined timing (see FIG. 4, etc.). At the time of transition to the second posture, the press roller 33 of the film splicing device 20 is in an open standby state, as shown in FIG. The transition to posture is performed smoothly.

With the table member 26 thus in the second posture and in the forward tilting posture, the packaging film 15a is positioned on the downward facing surface of the table member 26, but is held by suction. It stands by in a forward tilting posture together with the table member 26.例文帳に追加Then, at a predetermined timing when the remaining amount of the second material roll 15 becomes small, the press rollers 33 transition from the standby state to the contact state, and the pair of press rollers 33 press the packaging films 14a and 15a from both sides to a predetermined level. pinch with pressure. As a result, the adhesive tape attached to the leading edge of the packaging film 15a of the second original roll 15 on standby is pressed, and the two packaging films 14a, 15a are bonded and integrated. Along with this pasting work, the cutter device 27 in the first film setting device 21 is driven to cut the packaging film 14a in operation in the film width direction and separate it from the first film roll 14. FIG. As a result, the separated packaging film 14a is supplied to the packaging machine main body 2 as it is. At this time, the drive source such as the drive motor for the second film support shaft 13 is operated to start rotating the second film support shaft 13 and feed the packaging film 15 a from the second film roll 15 . As a result, the packaging film 15a is transported integrally with the packaging film 14a and continuously supplied to the packaging machine main body 2. As shown in FIG.

According to the embodiment described above, the packaging films 14a and 15a that have passed through the film splicing device 20 are supplied to the packaging machine main body 2 after moving above the second region R2. Therefore, for example, it is preferable to arrange a printing device for printing the date and other information, an inspection device, and the like in the area that moves above. In particular, in this embodiment, the surfaces of the packaging films 14a and 15a (outer surfaces of the package) are positioned upward in the section moving upward, so the printing device, the inspection device, etc. are located above the movement path of the film. Since the devices can be arranged, a space for arranging such devices can be secured, and these accessory devices can be arranged without increasing the plane area of the splicer device 10 .
