Description

  The present invention relates to a film sealing apparatus for sealing a tubular film containing contents and cutting a seal portion.

  As such a film sealing device, for example, there is a device as disclosed in Patent Document 1 below in which the applicant is the right holder. This device is attached to a film mounting part in a state where a tube-shaped film is folded in an annular shape, and is drawn out every time the contents are accommodated in the film to seal the sealing part and cut the sealing part. Separate the film containing the contents. Then, the film is drawn out and set to accommodate the next contents. As described above, the film feeding, contents storage, film feeding, sealing and cutting of the seal portion are repeatedly used. This will be described with reference to FIG.

  FIG. 11A shows a state immediately after the tubular film F is formed. A state in which this is folded into a ring shape is shown in FIG. The folding lines at the time of folding are indicated by L1 and L2. L1 is a line that makes a valley fold, and L2 is a line that makes a mountain fold. A folded state as shown in (b) is obtained by alternately repeating valley folding and mountain folding at predetermined intervals along the longitudinal direction of the tubular film.

  Next, the operation when the film F is set in the apparatus and the contents are accommodated will be described with reference to FIG. (A) shows the film F in the folded state. The outermost portion F1 of the film F folded in an annular shape is grasped by hand and pulled, moved in the center direction, and brought to the position of the conveying roller 100 (b). Next, the conveyance roller 100 is driven to send out the film F. After sending out to the position of (c), the conveyance roller 100 is stopped and the heater 101 with a cutter is operated. Thereby, the end F1 of the film F is melted and sealed. The heater 101 normally stands by at a position separated from the film F. After sealing, the content N is accommodated in the film F as shown in (d). Examples of the content N include raw garbage.

  When the contents N are stored, the transport roller 100 is driven again. This is shown in (e). When the film F is fed out by a predetermined amount, the transport roller 100 is stopped, the heater 101 is pressure-bonded to the film F, sealing is performed and a cutting action is performed on the sealing portion. Thereby, as shown to (f), the film F in which the content N was accommodated is isolate | separated. The separated film F containing the contents is disposed of.

A problem of the film sealing apparatus having such a configuration will be described. As shown in FIG. 13, since the tubular film folded in an annular shape is driven so as to be drawn by the transport roller 100, the seal portion sealed by the heater 101 is wrinkled several times. Film F is supplied in the form. That is, the thickness of the film F at the seal portion is not constant. Accordingly, the film F may not be separated cleanly even if the sealing portion in such a state is heated and sealed with a heater and cut. In such a case, the film F in which the contents N are accommodated is manually pulled to be forcibly separated, which is complicated.
Japanese Patent No. 3487784

  This invention is made | formed in view of the said situation, The subject is a film seal which can be made to perform a cutting | disconnection effect | action reliably, when sealing and cut | disconnecting the film in which the content was accommodated using a tubular film. Is to provide a device.

In order to solve the above-described problems, a film seal device according to the present invention includes:
A film sealing device for sealing a tubular film containing contents and cutting a seal portion,
A film driving unit for driving the film in the feeding direction and feeding the seal part of the film to a predetermined position;
A film seal portion for sealing and cutting the seal portion of the film;
A control unit for controlling the operation of the film drive unit and the film seal unit,
This film seal is
Film clamping means for clamping the vicinity of the seal portion of the film;
Film crimping means for crimping and heating the seal portion of the film;
A film cutting means for cutting the seal part of the film,
The control unit, after sending the film to a predetermined position and stopping it, operates the film clamping means and the film crimping means to heat and crimp the film and perform the cutting action on the seal part by the film cutting means, The film drive unit and the film seal unit are controlled so as to release the pressure-bonded state of the film pressure-bonding means and to drive the film by a predetermined amount in the return direction.

  The operation and effect of the film sealing apparatus having such a configuration will be described. The film driving unit drives the tubular film in the feeding direction, and feeds the film seal portion to a predetermined position. The seal portion refers to a portion to be sealed. The film seal part has a function of sealing and cutting the seal part. The control unit controls the operation of the film driving unit and the film seal unit. The film seal part has a film clamping means for clamping the vicinity of the seal part, a film crimping means for crimping and heating the seal part, and a film cutting means for cutting the seal part. The procedure until the film is sealed and cut is performed as follows.

  After the film is sent out by the film driving unit, it is stopped at a predetermined position. Next, the film clamping means and the film pressing means are operated to heat and press the film. The sealing portion is melted and sealed by heating the film by the film pressing means. Moreover, the cutting action is performed on the seal portion by the film cutting means. Next, the crimping state of the film crimping means is released, and the film is driven in the return direction by a predetermined amount. At this time, the film clamping state by the film clamping means is maintained. Therefore, by driving the film in the returning direction, the cut portion of the seal portion is pulled, so that the film can be reliably separated. Thereby, even if cutting is inadequate because the film is wrinkled, it can be forcibly separated. As a result, it is possible to provide a film sealing apparatus that can reliably perform a cutting action when sealing and cutting a film containing contents using a tubular film.

  In the present invention, the film crimping means includes a first pressure-bonding body and a second pressure-bonding body for pressure-bonding the seal portion of the film, and a heater for heating the film to the first pressure-bonding body and a film cutting means are provided. It is preferably incorporated so that the heating action and the cutting action can be performed simultaneously.

  The film press-bonding means includes a first press-bonded body and a second press-bonded body, and these first and second press-bonded bodies cooperate to press the film and perform heat sealing. Of the pair of pressure-bonded bodies, the first pressure-bonded body includes a heater and a film pressure-bonding means, which can be heated by the heater and simultaneously perform a cutting action. Since the film crimping means and the film cutting means can be driven in the same manner, the configuration of the film seal portion can be simplified.

In the present invention, the film crimping means includes a first crimping body and a second crimping body for crimping the seal portion of the film,
The film clamping means includes a first clamping body and a second clamping body that clamp the film,
The first clamping body is supported by the first crimping body in a state of being biased in the clamping direction by the first biasing means,
The second clamping body is supported by the second pressing body in a state of being biased in the clamping direction by the second biasing means,
The film driving unit is configured to directly transmit the driving force to the first pressure-bonding body and the second pressure-bonding body,
By driving the first crimping body and the second crimping body in the crimping direction, the first sandwiching body and the second sandwiching body are also driven in the same direction, and the first sandwiching body and the second sandwiching body have the film first. The film seal portion is configured so that the first and second pressure-bonding bodies are continuously driven against the urging force of the first and second urging means to crimp the film. It is preferable.

  According to such a configuration, the film crimping means includes the first crimping body and the second crimping body, and the first and second crimping bodies cooperate to crimp the film and perform heating and sealing. The film clamping means includes first and second clamping bodies, and the film can be clamped by the pair of clamping bodies. The first and second clamping bodies are supported by the first and second crimping bodies, respectively, and are urged in the clamping direction by the first and second urging means, respectively.

  According to this configuration, the sealing / cutting operation by the film seal portion is performed as follows. By driving the film driving unit, the driving force of the film driving unit is transmitted to the first and second crimped bodies. Thereby, the first and second crimping bodies are driven in the crimping direction. Along with the driving of the first and second crimping bodies, the first and second clamping bodies are also driven in the clamping direction. Then, the film is first clamped by the first and second clamping bodies, and thereafter, the first and second crimping bodies are continuously driven in the crimping direction in a form against the urging force by the urging means. If it will be in a crimping | compression-bonding state, the heating effect | action with respect to a seal part will be performed. Moreover, the cutting action with respect to a seal part is also performed.

  After the heat sealing is performed, the pressure-bonded state by the first and second pressure-bonded bodies is released, and the film can be driven in the return direction. According to the above configuration, it is possible to release the pressure bonding of the first and second pressure-bonded bodies while maintaining the state of being held by the first and second clamped bodies. In other words, the first and second sandwiching bodies and the first and second crimping bodies are both driven by the film driving unit, but the first and second sandwiching bodies are connected to each other via the urging means. -The crimping | compression-bonding state of a 1st, 2nd crimping | compression-bonding body can be cancelled | released, holding a film with a 2nd clamping body. In this state, the film is driven in the returning direction, so that the cut portion of the film can be forcibly separated.

<Configuration of film sealing device>
A preferred embodiment of a film seal device according to the present invention will be described with reference to the drawings. 1 and 2 are perspective views showing the configuration of the film sealing apparatus. FIG. 1 shows a state where no film is attached, and FIG. 2 shows a state where a film is attached.

  A guide member 2 formed in a bowl shape is attached on a support plate 1 having a relatively large area. The guide member 2 has a tapered side surface and a guide hole 2b formed at the bottom. FIG. 2 shows a state in which the folded tubular film F (see FIG. 12A (a)) is attached. The periphery of the guide member 2 functions as a film mounting portion. On the lower surface side of the support plate 1, a mechanism portion 3 for sealing and cutting the film is mounted. The operation when setting the film F in the annularly folded state is as described above. That is, the outermost portion F1 of the folded film F may be lifted by hand and pushed into the guide member 2 to the position of the hole 2b. Thereafter, the film F is drawn downward by driving the transport roller. The basic movement is as described in FIGS. 12A and 12B.

  Next, the mechanism unit 3 will be described. FIG. 3 is a perspective view of the film sealing device as seen from the back side. FIG. 4 is a plan view of the film sealing device as seen from the back side. 5 and 7 are side views of the mechanism unit. FIG. 6 is a side sectional view of the mechanism portion. 5 and 7 are drawings that are drawn upside down in combination with FIG. 3, and the film F moves from the bottom to the top. FIG. 6 is a diagram depicting the top and bottom correctly, and the film F moves from top to bottom.

  First, the function of the film seal part will be described. A first pressure-bonding body 4 and a second pressure-bonding body 5 are provided. As shown in FIG. 6 and the like, the first and second pressure-bonding bodies 4 and 5 have a standby position separated from each other and a pressure-bonding surface. It is configured to be movable (see arrows A and B) between a crimping position (see FIG. 7) where the film F is brought into contact with each other and crimped. The crimp surfaces 4a and 5a (corresponding to the film crimping means) of the first and second crimp bodies 4 and 5 are formed in a line shape extending in the width direction corresponding to the shape of the seal portion of the film F. A heater 6 extending in a line shape is attached to the pressure-bonding surface 4 a of the first pressure-bonding body 4. The heater 6 is a metal resistor and is heated by a heating circuit (not shown). Further, a cutting wire 7 (corresponding to a film cutting means) extending in a line shape is provided on the surface of the heater 6 like the heater 6. A cover member 8 is provided so as to cover the heater 6 and the cutting wire 7. The cover member 8 is a sheet member made of Teflon (registered trademark). A support member 9 made of silicon rubber is attached to the pressure-bonding surface 5 a of the second pressure-bonding body 5. The film F is pressure-bonded between the pair of pressure-bonding surfaces 4a and 5a.

  Two spring support shafts 10 are implanted on the end surface of the first crimping body 4 opposite to the crimping surface 4a. A first spring 11 is inserted into the spring support shaft 10. The first spring 11 functions as a first urging means and is formed by a compression coil spring. Two spring support shafts 12 are also planted on the surface of the second crimping body 5 opposite to the crimping surface 5 a, and the second spring 13 is inserted in the same manner as the first spring 11. The second spring 13 functions as second urging means.

  A first clamping body 14 (corresponding to a film clamping means) that can move relative to the first crimping body 4 is attached to and supported by the first crimping body 4. The first clamping body 14 is formed in a substantially U shape in a side sectional view so as to surround the first pressure-bonding body 4. The front end portion of the first clamping body 14 functions as a clamping surface 14a, and a first clamping member 15 made of silicon rubber is attached. The first spring 11 described above acts on the end surface 14b of the first sandwiching body 14 opposite to the sandwiching surface 14a. Therefore, in the separated position shown in FIG. 6, the end surface 14 b of the first clamping body 14 is in contact with the rear end surface 4 b of the first pressure-bonding body 4 by the urging force of the first spring 11. Further, in this state, the clamping surface 14a is set to protrude from the crimping surface 4a.

  A second clamping body 16 (corresponding to a film clamping means) that can move relative to the second crimping body 5 is attached to and supported by the second crimping body 5. The 2nd clamping body 16 is also formed in the substantially U shape by the side sectional view. The tip of the second sandwiching body 16 functions as a sandwiching surface 16a, and a second sandwiching member 21 made of silicon rubber is attached. The second spring 13 described above acts on the end surface 16b of the second sandwiching body 16 opposite to the sandwiching surface 16a. Therefore, in the separated position shown in FIG. 6, the end surface 16 b of the second clamping body 16 is in contact with the rear end surface 5 b of the second pressure-bonding body 5 by the urging force of the second spring 13. Further, in this state, the clamping surface 16a is set to protrude from the crimping surface 5a.

  The guide plate 17 is coupled to the first pressure-bonding body 4 with screws 18 so that the first clamping body 14 can smoothly move relative to the first pressure-bonding body 4 (see FIG. 3). The first clamping body 14 is guided between the first pressure-bonding body 4 and the guide plate 17. Similarly, the guide plate 19 is coupled to the second pressure-bonding body 5 by screws 20 so that the second holding body 16 can smoothly move relative to the second pressure-bonding body 5. The second clamping body 16 is guided between the second crimping body 5 and the guide plate 19.

  The first and second clamping bodies 14 and 16 are provided below the first and second crimping bodies 4 and 5. That is, it arrange | positions in the downstream of the feed direction of a film.

  Next, the structure of the seal drive unit that drives the film seal unit will be described. The seal drive unit includes a drive motor 22 as a drive source. A drive plate 23 is coupled to the motor shaft of the drive motor 22. The drive link member 24 is pivotally supported around the rotation shaft 24a. In the drive link member 24, a first link shaft 24b and a second link shaft 24c are implanted at a location separated from the rotation shaft 24a by a predetermined radial distance. The drive plate 23 and the first link shaft 24b are connected by a connecting bar 25. Although not shown in FIG. 3, a connecting shaft is implanted at a predetermined radial distance from the rotation center of the drive plate 23 (see FIG. 5), and between this connecting shaft and the first link shaft 24 b. A connecting bar 25 is stretched over the frame. In the connection shaft, the drive plate 23 and the connection bar 25 are relatively rotatable, and in the first link shaft 24b, the connection bar 25 and the drive link member 24 are relatively rotatably connected.

  The first pressure-bonding body support plate 26 supports the first pressure-bonding body 4 in a fixed state. A pair of side surface portions 26 a are formed on both sides in the width direction of the first pressure-bonding body support plate 26. A link shaft 26b is planted on the side surface portion 26a. The first link lever 27 is connected between the link shaft 26b and the first link shaft 24b. Similarly, the second pressure-bonding body 5 is supported on the second pressure-bonding body support plate 28 in a fixed state. A pair of side surface portions 28 a are formed on both sides in the width direction of the second pressure-bonding body support plate 28. A link shaft 28b is planted on the side surface portion 28a. A second link lever 29 is connected between the link shaft 28b and the second link shaft 24c. The film seal portion is driven by the link mechanism as described above. The same link mechanism is also provided on the side surface on the opposite side in the width direction. By driving the drive motor 22, the drive link member 24 can be rotated to drive the first pressure-bonding body 4 and the second pressure-bonding body 5 simultaneously.

  Guide mechanisms 30 for smoothly guiding the first pressure-bonding body 4 and the second pressure-bonding body 5 are provided on both sides in the width direction of the first and second pressure-bonding bodies 4 and 5. The guide mechanism 30 includes a fixed portion that is fixed to the frame member 31 and a movable portion that is fixed to the side surface portions 26a and 28a.

  A transport roller pair 32 is provided as a film driving unit for sending out the film F. The conveyance roller pair 32 is provided at two locations along the width direction. The film F is configured to pass between the two conveyance roller pairs 32. A drive motor 33 for driving the transport roller pair 32 is provided (see FIG. 3), and is connected to the transport roller pair 32 via a transmission mechanism (deceleration mechanism) (not shown). A control circuit 34 (corresponding to a control unit) is mounted on the support plate 1 and controls the operation of each unit of the film seal apparatus.

<Control block>
Next, the control-related configuration will be described with reference to FIG. The control unit 40 is a central unit that controls the operation of each part of the apparatus. The roller motor drive unit 41 controls a drive motor 33 for driving the transport roller 32. The seal motor drive unit 42 controls the drive motor 22 that drives the film seal unit. The heater driving unit 43 is configured by a heating circuit that drives the heater 6.

  In the timer setting unit 44, the drive time of the heater 6 and the drive motors 22 and 33 is set. The control unit 40 drives the heater 6 and the like according to the set time. The switch 45 functions as a start switch for performing a sealing operation. The LED drive unit 46 controls the lighting of the LED 47, and displays to the outside whether the film seal device is in a sealed state or in a usable state.

<Description of sealing operation>
Next, the operation when the film F is sealed will be described with reference to the operation diagram of FIG. 9 and the time chart of FIG. First, the switch 45 is turned on (t _{1 in} FIG. 10). In response to the command from the switch 45, the control unit 40 causes the drive motor 33 to rotate forward. Thereby, the conveyance roller pair 32 is rotated in the feeding direction (arrow D in FIG. 9A), and the film F is fed downward (arrow C). The time for normal rotation of the drive motor 33 is set in the timer setting unit 44 in advance, and the drive motor 33 is stopped when a predetermined time elapses (time t ₂ ). Thereby, the film F is fed out by a predetermined amount, and the seal portion of the film F is set at the position of the heater 6. The seal portion refers to a portion to be sealed and does not mean that any identification mark is attached to the film F. Of course, such a mark may be attached.

  Next, simultaneously with the stop of the drive motor 33, the drive motor 22 is rotated (normally rotated) in order to drive the first and second pressure-bonding bodies 4 and 5. The first and second pressure-bonding bodies 4 and 5 are driven in a direction approaching each other from the standby position (FIG. 9B). The first and second sandwiching bodies 14 and 16 respectively supported by the first and second pressure-bonding bodies 4 and 5 are also driven in a direction approaching each other. Since the clamping surfaces 14a and 16a of the first and second clamping bodies 14 and 16 protrude from the crimping surfaces 4a and 5a of the first and second crimping bodies 4 and 5, first, the clamping surfaces 14a and 16a are projected. The two come into contact with each other (FIG. 9B). Thereby, the 1st, 2nd clamping bodies 14 and 16 will be in the state which cannot move any more.

However, the drive motor 22 is still in a driving state, and the first and second crimping bodies 4 and 5 are further driven in a direction in which the crimping surfaces 4a and 5a approach each other. At this time, the first spring 11 and the second spring 13 are gradually compressed. FIG. 7 and FIG. 9 (c) show a state in which the crimping surfaces 4a and 5a are in contact with each other. The drive motor 22 is stopped for a predetermined time set in advance and then stopped (t ₃ ). Simultaneously with this stop, the heater 6 is heated. The transition of the temperature of the heater 6 is shown in FIG. The heater 6 is normally at a temperature as low as room temperature, but is heated to increase the temperature to a predetermined heating temperature (T2) (see FIG. 10). When a predetermined heating time set in advance elapses, the heater 6 is turned off, the heater 6 is naturally cooled, and the temperature decreases. As already described with reference to FIG. 6, since the cutting wire 7 is provided on the heater 6 and the surface, the cutting action is performed at the same time as the heater 6 is heated. Therefore, the sealing portion is welded to seal the contents, and the cutting action is also performed on the sealing portion.

When the heater 6 is turned off and a predetermined cooling time has elapsed, the drive motor 22 is reversely rotated to move the first and second pressure-bonding bodies 4 and 5 in the opening direction. The time for reversing can be set to a time during which the first and second pressure-bonding bodies 4 and 5 can be opened slightly. Even if the first and second crimped bodies 4 and 5 in the crimped state start to be driven in the opening direction (arrows A ′ and B ′ in FIG. 9D), the urging force of the first spring 11 and the second spring 13 is not increased. Since it is acting, the 1st and 2nd clamping bodies 14 and 16 maintain the state which clamped the film F (refer FIG.9 (d)). The drive motor 22 is slightly reversed and then stopped (t ₆ ). At the same time, the drive motor 33 is reversed. Thereby, the conveyance roller pair 32 is rotated in the opposite direction (arrow E in FIG. 9D), and the film F is driven in the return direction. The amount of reverse rotation of the conveying roller pair 32 may be small. By the returning operation of the film F, the cutting portion by the cutting wire 7 is forcibly separated (see FIG. 9E). The return amount may be such that the film F and the conveying roller pair 32 are not caught. Thereby, even if the cutting | disconnection of the film F by the cutting wire 7 is inadequate, the film F in which the content was accommodated can be isolate | separated reliably.

After the reverse rotation of the drive motor 33 is completed (t ₇ ), the drive motor 22 is driven in reverse to return to the standby position (t ₈ ) in order to return the first and second crimped bodies 4 and 5 to the standby position. In the middle of the return of the first and second crimping bodies 4 and 5 to the standby position, the holding of the film F by the first and second clamping bodies 14 and 16 is also released. Thereby, the film F in which the contents are accommodated falls. After the drive motor 22 is stopped, the drive motor 33 is rotated forward in order to move the film returned by the return operation to a position where a predetermined seal is performed. After the drive motor 33 is rotated forward for a predetermined time, the drive motor 33 is stopped (t ₉ ). Thereby, one cycle of operation is completed.

The LED indicating that the contents can be stored in the film F is turned off at time t ₁ and turned on at time t ₉ when the operation of one cycle is completed. By confirming this lighting, it is displayed outside that the contents may be accommodated in the film F. Moreover, while LED indicating that they offer the sealing operation of the film F is also provided, from the time t ₁ of t _8, lit.
