<4. Configuration of thermal fusion device>

The thermal welding device 40 includes a press section 41, a cutting section 42, and a welding motor 43. The press section 41 includes a heater (not shown), and is connected to the welding motor 43 via a connection member 44 inserted into the opening 10 a (see FIG. 1) of the partition plate 10. Driven by the welding motor 43, the press section 41 moves up and down via the connection member 44.

The annular cutter section 42 is arranged along the outer periphery of the press section 41. The cutter section 42 is moved up and down in association with the press section 41 by driving of the welding motor 43.

When the thermal welding device 40 is driven, the press portion 41 presses the sealing member 80 a sent out from the sending-out device 30 against the flange portion (not shown) of the cup container H. Thereby, the sealing member 80a is thermally welded to the flange portion of the cup container H. That is, the heat welding device 40 seals the upper surface of the cup container H by heat welding of the sealing member 80a.

The cutter unit 42 cuts the periphery of the sealing member 80 a fused to the flange portion of the cup container H in a ring shape. Accordingly, an opening portion (not shown) having a diameter substantially the same as the outer diameter of the flange portion of the cup container H is formed in the sealing member 80a. That is, the sealing member 80 a is opened in a predetermined area by thermal welding of the thermal welding device 40. The take-up roll 90 takes out the sealing member 80 a which is drawn out from the supply roll 80 and is opened in a predetermined area by thermal fusion of the thermal fusion device 40.

<5. Operation of sealing device>

In the sealing device 1 configured as described above, the drive shaft 25b of the conveyance motor 25 starts to rotate clockwise with a certain amount of rotation when viewed from the right side (viewed from the direction of arrow A in FIG. 2) by a predetermined operation of the operation unit 3. . As a result, the sealing device 1 starts to operate, and the first arm 21 in the folded position (see FIG. 4) starts to rotate clockwise when viewed from the right side. In addition, the second arm 22 starts to rotate clockwise around the second connecting portion 22 b as viewed from the right side.

At this time, as the first arm 21 rotates, the speed component of the first arm 21 in the guide direction GD (forward direction) gradually increases from zero. That is, in the folded position (see FIG. 4), the holder 23 can be started slowly by the first arm 21 and the second arm 22.

Thereby, the flange portion 23b of the holder 23 starts to slide on the guide rail 24, and the holder 23 starts to move in the guide direction GD (front direction). At this time, the roller 27 a of the slider 27 starts to rotate on the rear flat portion 29 a of the lower rail 29.

As shown in FIG. 5, when the first connection portion 22 a (the front end portion of the first arm 21) reaches the lowest point, the speed component of the first arm 21 that moves in the guide direction GD (front direction) becomes the largest. At this time, the moving speed of the holder 23 also becomes the maximum.

Thereafter, as shown in FIG. 6, the roller 27a is rotated on the inclined portion 29c. Accordingly, as the holder 23 moves forward, the slider 27 moves upward against the urging force of the urging portion, and the support plate 26 also moves upward.

Thereafter, as shown in FIG. 7, the first arm 21 is disposed in the extended position, the conveyance motor 25 is stopped, and the movement of the holder 23 is completed. At this time, the roller 27a is disposed on the front flat portion 29b, and the support plate 26 is disposed higher in the folded position (see FIG. 4). Square office.

From the state of FIG. 5 to the state of FIG. 7, the speed component of the first arm 21 in the guide direction GD (forward direction) gradually decreases from a maximum value. That is, in the extended position, the holder 23 can be stopped slowly by the first arm 21 and the second arm 22.

When the first arm 21 is disposed in the extended position (see FIG. 7), the opening portion 23 a of the holder 23 is disposed more forward than the extraction outlet 2 a. The user puts contents such as drinks in the cup container H, and then inserts the cup container H into the opening portion 23 a of the holder 23. Thereby, the cup container H in which the contents are put is held by the holder 23.

In the extended position (see FIG. 7), since the roller 27 a is disposed on the front flat portion 29 b, the roller 27 a can horizontally receive the load of the holder 23 holding the cup container H in which the contents are placed. This prevents the holder 23 from falling into the housing 2 when the cup container H is detached from the holder 23.

Thereafter, by a predetermined operation of the operation unit 3, the conveyance motor 25 is reversed, and the first arm 21 is moved from the extended position (see FIG. 7) to the folded position (see FIG. 4). At this time, similarly to when the first arm 21 moves from the folded position to the extended position, the holder 23 is slowly started by the first arm 21 and the second arm 22. When the first connecting portion 22a (the front end portion of the first arm) reaches the lowest point, the moving speed of the holder 23 is also maximized. Thereafter, the retainer 23 performs a slow stop from the maximum speed. This prevents the contents of the cup container H held by the holder 23 from being spilled. In other words, by moving the holder 23 at the maximum speed during the movement and driving with a slow start and a slow stop, leakage of the contents in the cup container H can be prevented. In addition, the support plate 26 that supports the cup container H is also slowly moved up and down near the extended position (see FIG. 7). By moving upward, leakage of the contents in the cup container H can be prevented.

Next, when the first arm 21 reaches the folded position (refer to FIG. 4), the conveyance motor 25 is temporarily stopped, and the opening portion of the upper surface of the cup container H is sealed by the sealing member 80 a drawn out from the supply roller 80 by the thermal welding device 40. Thereby, the contents are sealed in the cup container H.

After the thermal welding of the thermal welding device 40, the conveyance motor 25 is reversed, and the first arm 21 moves from the folded position (see FIG. 4) to the extended position (see FIG. 7) again. When the first arm 21 is disposed in the extended position, the conveyance motor 25 is stopped, and the cup container H whose contents are sealed by the sealing member 80a is disposed further forward than the take-out opening 2a. The user removes the cup container H from the holder 23.

At this time, as shown in FIG. 7, the cup container H is lifted upward by the support plate 26, and the upper end portion of the cup container H protrudes to be higher than the holder 23. Thereby, the user can easily hold the upper end portion of the cup container H.

Thereafter, by a predetermined operation of the operation unit 3, the conveyance motor 25 is reversed, the first arm 21 is moved again from the extended position (see FIG. 7) to the folded position (see FIG. 4), and in the folded position, the conveyance motor 25 is stopped. As described above, the operation of the sealing device 1 ends.

The first arm 21 is in a folded position in which the first arm 21 and the second arm 22 are arranged in a folded state (see FIG. 4) and an extended position in which the first arm 21 and the second arm 22 are arranged in an extended state ( (See Figure 7). Accordingly, compared with the configuration of the previous example, the moving distance of the holder 23 can be extended without extending the length of the first arm 21.

<6. First Modification>

The arrangement of the rotation shafts of the conveyance motor 25 of the conveyance device 20 of the present embodiment may be different from that described above. That is, the rotation shaft of the conveyance motor 25 may be arrange | positioned vertically. Thereby, the first arm 21 and the second arm 22 rotate in the horizontal plane. In this case, the moving distance of the holder 23 can be extended.

<7. Second Modification>

The arrangement of the supply unit 31 and the winding unit 32 of the sealing device 1 according to the present embodiment may be different from that described above. That is, the take-up section 32 may be arranged below the supply section 31 instead of the supply section 31 and the take-up section 32. Thereby, since the winding motor 33 can be arrange | positioned below, the center of gravity of the sealing device 1 can be lowered and stability can be improved.

<8. Third Modification>

As shown in FIG. 8, a gear box 12 may be provided on the right side (first arm 21 side) of the transport motor 25. In addition, in FIG. 8, the first arm 21 is disposed at the folded position. The gear box 12 includes a first gear (not shown) and a second gear (not shown) in the housing 12a. The first gear is concentric with the transmission shaft 25b and rotates integrally with the transmission shaft 25b. The second gear meshes with the first gear, and the number of teeth of the second gear is different from the number of teeth of the first gear.

One end of the first arm 21 is fixed to the shaft portion 13 of the second gear. That is, the transmission shaft 25b, which is a rotation shaft of the conveyance motor 25, is connected to the first arm 21 via the first gear (gear) and the second gear (gear). With the first gear and the second gear, the variable degree of freedom of the moving speed of the first arm 21 can be increased, and even the variable degree of freedom of the moving speed of the holder 23 can be increased. In addition, the number of gears of the gear box 12 is not limited to two, and may be plural.

In the folded position, the outer peripheral surface of the casing 12 a faces the second arm 22 in the radial direction of the rotation axis of the conveyance motor 25. At this time, the recessed portion 22 g of the second arm 22 receives a part of the gear case 12 and prevents interference between the gear case 12 and the second arm 22. Thereby, the second arm 22 and the gear box 12 are projected onto a plane including the rotation axis of the conveyance motor 25, and the conveyance device 20 can be made compact.

In addition, the housing 12 a may be omitted, and the first gear and the second gear may be exposed from the first arm 21 and the second arm 22. That is, the recessed part 22g of the second arm 22 only needs to accommodate the first gear and a part of the second gear. In this case, the second arm 22 is superimposed on the first gear and the second gear by being projected on a plane including the rotation axis of the transport motor 25, and the transport device 20 can be made compact.

According to this embodiment, the first arm 21 is between a folded position where the first arm 21 and the second arm 22 are arranged in a folded state and an extended position where the first arm 21 and the second arm 22 are arranged in an extended state. Between moves. Accordingly, compared with the configuration of the previous example, the moving distance of the holder 23 can be extended without extending the length of the first arm 21. Therefore, it is possible to suppress the increase in size of the conveying device 20 and improve the usability of the conveying device 20.

The first arm 21 has one end fixed to the transmission shaft 25 b of the conveyance motor 25 and extends in the radial direction of the conveyance motor 25. The second arm 22 is connected to the other end of the first arm 21 via the first connection portion 22a, and is connected to the holder 23 via the second connection portion 22b. This makes it possible to easily perform slow start and slow stop of the holder 23.

In addition, in the extended position and the folded position, the transmission shaft 25b, the first connection portion 22a, and the second connection portion 22b are disposed on a substantially straight line. Thereby, the moving distance of the holder 23 can be further extended.

In the folded position, the outer peripheral surface of the casing 25a of the transport motor 25 faces the second arm 22 in the radial direction, and the second arm 22 has a recessed portion 22g that accommodates a part of the casing 25a. Thereby, the second arm 22 and the housing 25a are projected onto a plane including the rotation axis of the conveyance motor 25, and the conveyance device 20 can be made compact.

In addition, the rotation shaft of the conveying motor 25 is connected to the first arm 21 via a first gear (gear) and a second gear (gear), and in the folded position, the second arm 22 may include a housing for the first gear and the second gear A part of the recessed portion 22g. Thereby, the second arm 22 is superimposed on the first gear and the second gear when projected on a plane including the rotation axis of the conveyance motor 25, and the conveyance device 20 can be made compact.

In addition, the rotation shaft of the conveyance motor 25 is arrange | positioned horizontally. Thereby, the first arm 21 and the second arm can be rotated in a vertical plane. Therefore, the length of the conveying device 20 in the left-right direction (width direction) and the front-rear direction (depth direction) can be shortened, and the installation area of the conveying device 20 can be reduced.

In addition, since the conveyance motor 25 is a brushless DC motor, the size of the conveyance motor 25 can be reduced compared with a configuration using an AC motor. Furthermore, the holder 23 may be moved by performing PWM (Pulse Width Modulation) control on the conveyance motor 25. Thereby, the degree of freedom of the moving speed of the holder 23 can be increased. In other words, by changing the rotation speed of the transmission shaft 25b as the rotation shaft of the conveyance motor 25, the degree of freedom of the movement speed of the holder 23 can be increased. Therefore, the usability of the conveyance device 20 can be further improved.

In addition, in the extended position, the cup container H (conveyance) is disposed further forward than the take-out opening 2a, and in the folded position, the holder 23 is housed in the frame 2 and Thermal sealing of the sealing member 80a is performed. Thereby, the sealing device 1 can be easily realized. In addition, since the moving distance of the holder 23 is long, the cup container H can be easily attached and detached from the take-out port 2a in the extended position.

The supply unit 31 and the winding unit 32 are provided in parallel in the up-down direction. Thereby, the length of the sealing device 1 in the left-right direction (width direction) and the front-back direction (depth direction) can be shortened, and the installation area of the sealing device 1 can be reduced.

The supply unit 31 and the take-up unit 32 are disposed in a staggered manner in the left-right direction. This prevents interference between the sealing member 80a on the supply side and the sealing member 80a on the curling side.

In addition, the holder 23 has an opening portion 23 a that supports the peripheral surface of the transported object including the cup container H, and the heat welding device 40 seals the upper surface of the cup container H by heat welding of the sealing member 80 a. Accordingly, the sealing device 1 can easily seal the contents into the cup container H. In addition, when the holder 23 is moved, the contents in the cup container H can be prevented from being spilled.

In addition, when the winding unit 32 is arranged below the supply unit 31 and the winding motor 33 is arranged below, the center of gravity of the sealing device 1 can be lowered and stability can be improved.
