[0030]
As already described, the operation lever 15 is supported by the L-shaped lever so as to be rotatable around the rotation axis 15a. The ends of the second arm portions 15d of the pair of L-shaped levers are connected by a connecting shaft 15e. A lock lever 20 is provided to be rotatable around the axis (axis center) of the connecting shaft 15e. An engaging recess 20a is formed at the end of the lock lever 20 opposite to the rotational axis. Further, a tension spring 21 (corresponding to the second spring member) is provided and urges the lock lever 20, but in the state of FIG. 4, a stopper (not shown) is provided so as not to rotate any more. ing. The engaging recess 20 a engages with the lock pin 6 provided in the fixed main body 3. The engaging recess 20a and the lock pin 6 correspond to second holding means.
[0031]
On the other hand, the engagement lever 17 is provided on the upper surface side of the movable main body 2 and is rotatably supported around the rotation axis 17a. An engagement recess 17b is formed at the end of the engagement lever 17 on the opposite side to the rotation axis 17a. The engaging recess 17b can be engaged with the connecting shaft 15e. In the state shown in FIG. 4, the operating lever 15 is engaged by the engaging lever 17 and cannot rotate about the rotation axis 15 a. A tension spring 18 (corresponding to a spring member) is hung in the vicinity of the engagement recess 17b of the engagement lever 17, and urges the engagement lever 17 in a direction to engage with the connecting shaft 15e. Further, an engagement release pin 19 (corresponding to a release member) is provided in the vicinity of the rotation axis 17 a of the engagement lever 17. The engagement release pin 19 and the engagement lever 17 are integrally coupled. The tip 19 a of the disengagement pin 19 can abut on the upper surface of the fixed main body 3. The disengagement pin 19 and the upper surface of the fixed main body 3 correspond to a release means.
[0032]
As shown in FIG. 7, the film sheet F drawn from the roll R is guided by the guide roller 30 and pulled out. The film sheet F can be pulled out by an operator by hand. A cutter 31 is disposed in the vicinity of the guide roller 30. The film sheet F can be cut by the cutter 31.
[0033]
<Operation of First Embodiment>
Next, the effect | action of the heat seal apparatus for containers is demonstrated centering on FIGS. FIG. 6 shows a state where the movable main body 2 is opened (first position), and a state where the container receiving portion 5 of the fixed main body 3 is exposed. Therefore, the container receiving portion 5 can receive the container C. Set the container C and put the contents in the container. Thereafter, the film sheet F is pulled out by hand and pulled out to a position where the opening of the container C is completely closed.
[0034]
The operation lever 15 is engaged by an engagement lever 17. This engaged position of the engagement lever 17 is defined as the initial position of the operation lever 15. That is, the operation lever 15 is locked so as not to rotate around the rotation axis 15a. Therefore, the engagement lever 17 corresponds to a first holding unit that holds the operation lever 15 (manual operation unit) in a locked state. By holding the grip portion 15 b of the operation lever 15 by hand and lowering it downward, the movable main body portion 2 rotates around the rotation axis 7. Thereby, the movable main body 2 is moved in the closing direction (from the first position to the second position).
[0035]
As shown in FIG. 7, when the movable main body 2 is rotated, the tip 19 a of the disengagement pin 19 comes into contact with the fixed main body 3. Release the engaged state. However, the operation lever 15 and the lock lever 20 can be continuously rotated around the rotation axis 7. Further, by releasing the engagement by the engagement lever 17, the operation lever 15 can be rotated around the rotation axis 15 a provided in the movable main body 2. Then, the engaging recess 20 a of the lock lever 20 engages with the lock pin 6.
[0036]
In the state shown in FIG. 7, the rotation axis 15 a of the operation lever 15 is on the left side of the straight line L connecting the rotation axis 15 e of the lock lever 20 and the lock pin 6. In this state, the operation lever 15 is biased by the tension spring 21 so as to move in the direction of the initial position (clockwise in FIG. 7). When the operation lever 15 further rotates from the state shown in FIG. 7, the rotation axis 15a moves to the right side of the straight line L as shown in FIG. In other words, the dead point has been exceeded. In this state, the operation lever 15 is urged by the tension spring 21 in the reverse direction (counterclockwise in FIG. 7) compared to before the dead point is exceeded. That is, the operation lever 15 is held in a direction in which it is locked with respect to the fixed main body 3. In the state of FIG. 8, it is defined that the operation lever 15 is in the final position. Moreover, the movable main body 2 is in the second position.
[0037]
Further, during the transition from the state of FIG. 7 to the state of FIG. 8, the heater surface side of the heater support 10 is pressed against the opening peripheral portion of the container C (see FIG. 3B). As a result, the heater support 10 is slightly lifted upward against the urging force of the compression spring 13, and a pressing force acts on the peripheral edge portion of the opening. In addition, the heater support 10 is moved, so that the switch 14 is turned ON and the deformed heater 11 is energized. When the heater 11 is heated, the film sheet F in contact with the heater 11 is heated, and the film sheet F is heat-sealed to the peripheral edge portion of the opening. The heating method by the heater 11 is preferably performed by an impulse method. In addition, a temperature sensor is provided, and temperature control is also performed. In the case of the impulse type, the film sheet is thermally fused by instantaneous heating control.
[0038]
Further, the connecting shaft 15e of the operation lever 15 is in contact with the buffer member 16 (see FIG. 5), so that the impact when the operation lever 15 has been operated is mitigated. The buffer member 16 is made of rubber or the like. The buffer member 16 also functions as a stopper.
[0039]
Next, although it is a procedure when taking out container C, what is necessary is just to perform in the reverse direction so far. From the state of FIG. 8, the grip portion 15b of the operation lever 15 is operated and rotated clockwise. Thereby, the locked state at the final position of the operation lever 15 is released. When the operation lever 15 is further rotated, the connecting shaft 15e and the engagement lever 17 are engaged. If the operation lever 15 is further lifted in this state, the movable main body 2 can be lifted.
[0040]
According to the above structure, a film sheet can be heat-sealed to the opening peripheral part of a container, without moving the fixed main-body part 3 which sets a container. Therefore, the contents stored in the container will not spill out of the container.
[0041]
<Configuration of Second Embodiment>
Next, the configuration of the apparatus according to the second embodiment will be described. FIG. 9 is a perspective view showing the moving mechanism in a state where the movable main body portion is in the first position. FIG. 10 is a perspective view showing the moving mechanism in a state where the movable main body portion is in the second position. FIG. 11 is a side view showing the moving mechanism in a state where the movable main body portion is in the first position. FIG. 12 is a side view illustrating a state where the movable main body portion is in the middle of transition from the first position to the second position. FIG. 13 is a side view showing the moving mechanism in a state where the movable main body portion is in the second position. The moving mechanism is provided with the same mechanism on both sides in the width direction.
[0042]
As shown in FIG. 9 and the like, the operation lever 15 (corresponding to a manual operation unit) includes a grip portion 15b and is configured to be rotatable around the rotation axis 15a. Further, on both the left and right sides of the operation lever 15, a straight arm portion 151 and a fan-shaped portion 152 are integrally formed. These can be molded as a plate-like member by a sheet metal press. Further, a first spring hanging shaft 153 is attached to the arm portion 151, and a second spring hanging shaft 154 is attached to the side surface portion 2 a of the movable main body portion 2. A tension spring 40 is attached between the spring hanging shafts 153 and 154. Thus, in FIG. 11, the operation lever 15 is urged clockwise around the rotation axis 15a. The operation lever 15 is provided with a stopper (not shown) so as not to rotate clockwise from the illustrated position.
[0043]
Next, the lock lever 20 will be described. The lock lever 20 is rotatably supported around the rotation axis 155 set in the sector 152 of the operation lever 15. Further, a tension spring 41 is hung between a spring hooking hole 200 provided in the lock lever 20 and a spring hooking hole 156 provided in the operation lever 15. Accordingly, the lock lever 20 is coupled to the operation lever 15 so as to be able to rotate counterclockwise around the rotation axis 155. In addition, the lock lever 20 is formed with an arc-shaped long hole 201 to allow the lock lever 20 to rotate. Further, the range in which the lock lever 20 can rotate is restricted by the contact between the long hole 201 and the rotary shaft core 15a (shaft member). The pair of left and right lock levers 20 are connected by a connecting member 202 (see FIG. 10).
[0044]
Next, the structure of the 1st holding means for hold | maintaining the operation lever 15 with respect to the movable main-body part 2 in a 1st position is demonstrated. 14 and 15 are side sectional views showing the configuration and operation of the pressing member. 16 and 17 are enlarged views for explaining the holding state and the releasing operation of the operation lever by the pressing member.
[0045]
As shown in FIG. 16, the movable main body 2 includes a ceiling cover portion 2b and vertical wall portions 2c attached to both sides thereof. A through hole is formed in the vertical wall portion 2c, and a slide shaft 50 functioning as a pressing member and a shaft-like member is slidably fitted therein. A pair of slide shafts 50 are provided on both sides in the width direction, and the configuration is the same. The slide shaft 50 includes a large diameter portion 50a, a small diameter portion 50b, and a tip portion 50c. A compression coil spring 51 is fitted into the small diameter portion 50b. The upper end of the compression coil spring 51 is set on the lower surface 2d of the vertical wall 2c, and the lower end is set at the boundary position between the tip 50c of the slide shaft 50 and the small diameter part 50b. Thereby, the slide shaft 50 is urged so as to move downward. However, the protrusion 2e formed inside the through hole into which the slide shaft 50 is fitted is prevented from moving downward from the position shown in FIG.
[0046]
The vertical wall 2c is formed with an insertion hole 2f that communicates with the side surface 2a, into which a steel ball 52 (equivalent to an engaging member or a metal ball) is inserted. Further, an engagement hole 157 (corresponding to an engagement portion) is formed in the fan-shaped portion 152 of the operation lever 15, and the steel ball 52 can enter here. In the state shown in FIG. 16, the steel ball 52 is pushed by the large diameter portion 50 a, and the engaged state between the steel ball 52 and the operation lever 15 is maintained. That is, the operation lever 15 is held in a locked state.
[0047]
A pair of core support plates 2g are attached to the upper surface of the movable main body 2, and the core 2h is supported between them. Thereby, the roll R of a film sheet can be supported. Further, damper mechanisms 25 are provided on both side surfaces of the movable main body 2 to improve the operation feeling of the operation lever 15.
[0048]
<Operation of Second Embodiment>
Next, the effect | action of the heat seal apparatus for containers which concerns on 2nd Embodiment is demonstrated. FIG. 9 shows a state in which the movable main body 2 is opened (first position), and a state in which the container receiving portion 5 of the fixed main body 3 is exposed. Therefore, the container receiving portion 5 can receive the container (not shown). Set the container and place the contents in the container. Thereafter, the film sheet F is pulled out by hand and pulled out to a position where the opening of the container is completely closed. In addition, although the shape of the container receiving part 5 is formed in the rectangle, of course, this is only an illustration. The container receiving part 5 can be exchanged according to the shape of the container.
[0049]
Next, the grip 15b of the operation lever 15 is held by hand, and the movable main body 2 is moved from the first position to the second position. The movable main body 2 is rotated around the rotation axis 7. Further, as described with reference to FIG. 16, the operation lever 15 is held by the steel ball 52, and the operation lever 15 cannot be rotated relative to the movable main body 2.
[0050]
As the movable main body 2 is rotated, the tip 50c of the slide shaft 50 comes into contact with the upper surface of the fixed main body 3. The moment of contact is shown in FIGS. That is, the slide shaft 50 cannot be rotated any more, but the other portions are further rotated. As a result, as shown in FIG. 17A, the slide shaft 50 can relatively raise the through-hole formed in the movable main body 2 against the urging force of the compression coil spring 51. Then, as shown in (b), when the slide shaft 50 rises to a position where the steel ball 52 faces the small diameter portion 50b, the steel ball 52 can escape from the engagement hole 157. At the moment when the slide shaft 50 comes into contact with the fixed main body 3, the engagement recess 20 a of the lock lever 20 is not yet engaged with the lock pin 6, but the steel ball 52 can be withdrawn from the engagement hole 157. In this state, the lock pin 6 is engaged. That is, the lock pin 6 and the engagement recess 20a function as a second holding unit. When the steel ball 52 escapes from the engagement hole 157, the operation lever 15 can be rotated from the initial position to the final position.
[0051]
FIG. 13 is a diagram illustrating an operation completion state. In the process of operating the operation lever 15, the axis L2 of the tension spring 40 gets over the rotary shaft 15a. In the state shown in FIG. 12, the operating lever 15 is urged clockwise by the tension spring 40 by the tension spring 40, whereas in the state shown in FIG. 13, it is urged counterclockwise. The lock lever 20 is also biased counterclockwise by the tension spring 41. Thereby, the operation lever 15 is reliably held in the locked state at the second position. The mechanism for performing heat sealing may be the same as in the first embodiment.

Next, although it is a procedure when taking out a container, what is necessary is just to perform in the reverse direction so far. From the state shown in FIG. 13, the grip portion 15b of the operation lever 15 is operated and rotated clockwise. Thereby, the locked state at the final position of the operation lever 15 is released. When the operation lever 15 is further rotated, the steel ball 52 and the engagement hole 157 of the operation lever 15 are engaged. If the operation lever 15 is further lifted in this state, the movable main body 2 can be lifted.

<Another embodiment>
(1) In the present embodiment, the movable main body is configured to rotate, but may be configured to linearly move in the vertical direction.
(2) About the structure of a moving mechanism, the structure disclosed by this embodiment is an example, and various modifications can be considered. As the lock mechanism by the first and second holding means, an appropriate method such as not only mechanical engagement but also electromagnetic engagement, frictional force holding, and spring biasing can be adopted. Instead of integrally coupling the disengagement pin with the engagement lever, the disengagement portion may be configured at an appropriate location of the fixed main body portion and contacted with the engagement lever.
