<3. Configuration of feeding device>
As shown in FIGS. 1 to 3, the feeding device 30 is disposed at the upper part in the housing 2 and includes a supply unit 31, a winding unit 32, and a winding motor 33. The supply unit 31 includes a bar-shaped member 31a that extends horizontally. The rod-shaped member 31a is rotatably attached to the attachment plate 11. A supply roll 80 around which a sheet-like seal member 80a is wound is inserted through the rod-shaped member 31a. Thereby, the supply part 31 supports the supply roll 80 on a horizontal axis. For example, polyethylene or the like is used as the material of the seal member 80a.

  The winding part 32 has a bar-like member 32a extending horizontally. The rod-shaped member 32a is rotatably attached to the mounting plate 11, and is disposed above the rod-shaped member 31a. Thereby, the supply part 31 and the winding part 32 are arranged in parallel by the up-down direction. Further, the rod-shaped member 32a and the rod-shaped member 31a are arranged so as to be shifted in the left-right direction. That is, the supply unit 31 and the winding unit 32 are arranged so as to be shifted in the left-right direction. A winding roll 90 is inserted through the rod-shaped member 32a. Thereby, the winding part 32 supports the winding roll 90 on a horizontal axis.

  The winding motor 33 is composed of a brushless DC motor or the like, and is connected to the rod-shaped member 32a. Thereby, the winding motor 33 drives the winding unit 32 to rotate.

  Further, guide rollers 34 and 35 are provided on the left and right sides of the thermal welding apparatus 40, respectively. The guide rollers 34 and 35 are rotatably supported by the front and rear vertical columns 6.

<4. Configuration of thermal welding equipment>
The heat welding apparatus 40 includes a press part 41, a cutter part 42, and a welding motor 43. The press part 41 has a heater (not shown), and is connected to the welding motor 43 through a connecting member 44 inserted through the opening 10a (see FIG. 1) of the partition plate 10. The press part 41 moves up and down via the connecting member 44 by driving the welding motor 43.

  The annular cutter part 42 is arranged along the outer periphery of the press part 41. The cutter unit 42 moves up and down in conjunction with the press unit 41 by driving the welding motor 43.

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

  And the cutter part 42 cut | disconnects the circumference | surroundings of the sealing member 80a welded to the flange part of the cup container H circularly. Thereby, an opening (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 seal member 80a. That is, the seal member 80a opens a predetermined region by thermal bonding of the heat welding apparatus 40. The take-up roll 90 takes up the seal member 80 a that is pulled out from the supply roll 80 and has a predetermined area opened by the thermal welding of the thermal welding apparatus 40.

<5. Operation of sealing device>
In the sealing device 1 having the above-described configuration, the shaft 25b of the transport motor 25 starts to rotate clockwise with a predetermined amount of rotation when viewed from the right side (as viewed from the direction of arrow A in FIG. 2). . Thereby, operation | movement of the sealing apparatus 1 starts and the 1st arm 21 of a folding position (refer FIG. 4) begins to rotate clockwise seeing from a right side surface. Further, the second arm 22 starts to rotate clockwise around the second connecting portion 22b as viewed from the right side.

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

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

  As shown in FIG. 5, when the first connecting portion 22a (the tip portion of the first arm 21) reaches the lowest point, the velocity component in the guiding direction GD (forward direction) of the moving first arm 21 is maximized. . At this time, the moving speed of the holder 23 is also maximized.

  Thereafter, as shown in FIG. 6, the roller 27a rolls 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 at the extended position, the transport motor 25 is stopped, and the movement of the holder 23 is finished. At this time, the roller 27a is disposed on the front flat portion 29b, and the support plate 26 is disposed above the folding position (see FIG. 4).

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

  When the first arm 21 is disposed at the extended position (see FIG. 7), the opening 23a of the holder 23 is disposed in front of the outlet 2a. The user inserts the cup container H into the opening 23 a of the holder 23 after putting contents such as beverages in the cup container H. Thereby, the cup container H containing the contents is held by the holder 23.

  In the extended position (see FIG. 7), since the roller 27a is disposed on the front flat portion 29b, the load of the holder 23 holding the cup container H containing the contents can be received on a horizontal plane. Thereby, when the cup container H is attached to and detached from the holder 23, the holder 23 can be prevented from falling into the housing 2.

  Thereafter, the conveyance motor 25 is reversed by a predetermined operation of the operation unit 3, and the first arm 21 is moved from the extended position (see FIG. 7) to the folding position (see FIG. 4). At this time, similarly to the movement of the first arm 21 from the folded position to the extended position, the holder 23 is slowly started by the first arm 21 and the second arm 22. And when the 1st connection part 22a (front-end | tip part of a 1st arm) reaches the lowest point, the moving speed of the holder 23 will also become the maximum. Thereafter, the holder 23 slows down from the maximum speed. Thereby, the contents in the cup container H held by the holder 23 can be prevented from spilling. That is, the leakage of the contents in the cup container H can be prevented by driving the slow start and the slow stop while maximizing the moving speed of the holder 23 during the movement. In addition, the support plate 26 that supports the cup container H is also gently moved up and down in the vicinity of the extended position (see FIG. 7), so that the contents in the cup container H can be prevented from leaking.

  Next, when the first arm 21 reaches the folding position (see FIG. 4), the transport motor 25 is temporarily stopped, and the opening member on the upper surface of the cup container H is pulled out from the supply roll 80 by the heat welding device 40. Sealed by 80a. Thereby, the contents are enclosed in the cup container H.

  After heat welding of the heat welding device 40, the transport motor 25 is reversed, and the first arm 21 moves again from the folding position (see FIG. 4) to the extended position (see FIG. 7). When the first arm 21 is disposed at the extended position, the transport motor 25 is stopped, and the cup container H in which the contents are sealed by the seal member 80a is disposed forward of the outlet 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 projects upward from the holder 23. Thereby, the user can hold | grip the upper end part of the cup container H easily.

  Thereafter, the conveyance motor 25 is reversed by a predetermined operation of the operation unit 3, and the first arm 21 is moved again from the extended position (see FIG. 7) to the folding position (see FIG. 4). Stops. Thus, the operation of the sealing device 1 is completed.

  The first arm 21 is in a folded position (see FIG. 4) in which the first arm 21 and the second arm 22 are folded, and in a state in which the first arm 21 and the second arm 22 are extended. It moves between the extended positions (see FIG. 7). Thereby, compared with the structure of a prior art example, the moving distance of the holder 23 can be taken long, without lengthening the length of the 1st arm 21. FIG.

<6. First Modification>
In addition, arrangement | positioning of the rotating shaft of the conveyance motor 25 of the conveying apparatus 20 of this embodiment may differ from the above. That is, the rotation axis of the transport motor 25 may be arranged vertically. Thereby, the 1st arm 21 and the 2nd arm 22 rotate in a level surface. Even in this case, the moving distance of the holder 23 can be increased.

<7. Second Modification>
Further, the arrangement of the supply unit 31 and the winding unit 32 of the sealing device 1 of the present embodiment may be different from the above. That is, the supply unit 31 and the winding unit 32 may be interchanged, and the winding unit 32 may be disposed below the supply unit 31. Thereby, since the winding motor 33 can be arrange | positioned below, the gravity center of the sealing apparatus 1 can be lowered | hung and stability can be improved.

<8. Third Modification>
Further, as shown in FIG. 8, the gear box 12 may be provided on the right side (the first arm 21 side) of the transport motor 25. In FIG. 8, the first arm 21 is disposed at the folding position. The gear box 12 has a first gear (not shown) and a second gear (not shown) in the casing 12a. The first gear is provided concentrically with the shaft 25b and rotates integrally with the 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 shaft 25b, which is the rotation shaft of the transport motor 25, is connected to the first arm 21 via the first gear (gear) and the second gear (gear). The first gear and the second gear can increase the degree of freedom in changing the moving speed of the first arm 21, and in turn increase the degree of freedom in changing the moving speed of the holder 23. Note that the number of gears in the gear box 12 is not limited to two, and may be plural.

  In the folding position, the outer peripheral surface of the casing 12 a faces the second arm 22 and the radial direction of the rotation shaft of the transport motor 25. At this time, the recess 22 g of the second arm 22 accommodates a part of the gear box 12 and prevents interference between the gear box 12 and the second arm 22. Thereby, it projects on the plane containing the rotating shaft of the conveyance motor 25, the 2nd arm 22 and the gear box 12 overlap, and the compactness of the conveying apparatus 20 can be achieved.

  The casing 12 a may be omitted, and the first gear and the second gear may be exposed to the first arm 21 and the second arm 22. In other words, the recess 22g of the second arm 22 only needs to accommodate part of the first gear and the second gear. Even in this case, the second arm 22 and the first and second gears are projected onto a plane including the rotation axis of the transport motor 25, so that the transport device 20 can be made compact.

  According to the present embodiment, the first arm 21 extends from the folding position where the first arm 21 and the second arm 22 are folded, and the first arm 21 and the second arm 22 extending. Move between the extension positions. Thereby, compared with the structure of a prior art example, the moving distance of the holder 23 can be taken long, without lengthening the length of the 1st arm 21. FIG. Therefore, the usability of the transport device 20 can be improved while suppressing an increase in the size of the transport device 20.

  The first arm 21 extends in the radial direction of the transport motor 25 with one end fixed to the shaft 25 b of the transport motor 25. And the 2nd arm 22 is connected with the other end of the 1st arm 21 via the 1st connection part 22a, and is connected with the holder 23 via the 2nd connection part 22b. Thereby, the slow start and slow stop of the holder 23 can be performed easily.

  Further, in the extended position and the folded position, the shaft 25b, the first connecting portion 22a, and the second connecting portion 22b are arranged on a substantially straight line. Thereby, the moving distance of the holder 23 can be made longer.

  In the folding position, the outer peripheral surface of the housing 25a of the transport motor 25 faces the second arm 22 in the radial direction, and the second arm 22 has a recess 22g that accommodates a part of the housing 25a. Thereby, it projects on the plane containing the rotating shaft of the conveyance motor 25, the 2nd arm 22 and the housing 25a overlap, and the compactness of the conveyance apparatus 20 can be achieved.

  The rotation shaft of the transport motor 25 is connected to the first arm 21 via a first gear (gear) and a second gear (gear), and the second arm 22 is connected to the first gear and the second gear at the folding position. You may have the recessed part 22g which accommodates a part of. Thereby, it projects on the plane containing the rotating shaft of the conveyance motor 25, the 2nd arm 22, the 1st gear, and the 2nd gear overlap, and the compactness of the conveyance apparatus 20 can be achieved.

  Further, the rotation shaft of the transport motor 25 is horizontally arranged. Thereby, the 1st arm 21 and the 2nd arm 22 can be rotated in a perpendicular plane. Therefore, the length of the transport device 20 in the left-right direction (width direction) and the front-back direction (depth direction) can be shortened, and the installation area of the transport device 20 can be reduced.

  Moreover, since the conveyance motor 25 is a brushless DC motor, the conveyance motor 25 can be reduced in size compared with the structure using an AC motor. Note that the holder 23 may be moved by PWM control of the transport motor 25. Thereby, the freedom degree of variable of the moving speed of the holder 23 can be raised. That is, by changing the rotation speed of the shaft 25b that is the rotation axis of the transport motor 25, the degree of freedom in changing the movement speed of the holder 23 can be increased. Therefore, the usability of the transport device 20 can be further improved.

  In addition, the cup container H (conveyed material) is arranged in front of the outlet 2a at the extended position, and the holder 23 is housed in the housing 2 at the folding position to thermally weld the seal member 80a. Thereby, the sealing apparatus 1 is easily realizable. Moreover, since the moving distance of the holder 23 is long, the cup container H can be easily attached / detached away from the outlet 2a at the extended position.

  Further, the supply unit 31 and the winding unit 32 are arranged side by side in the vertical direction. Thereby, the length of the horizontal direction (width direction) and the front-back direction (depth direction) of the sealing apparatus 1 can be shortened, and the installation area of the sealing apparatus 1 can be made small.

  Further, the supply unit 31 and the winding unit 32 are arranged so as to be shifted in the left-right direction. Accordingly, interference between the supply-side seal member 80a and the take-up-side seal member 80a can be prevented.

  Moreover, the holder 23 has an opening 23a that supports the peripheral surface of the conveyed product made up of the cup container H, and the heat welding device 30 seals the upper surface of the cup container H by heat welding of the seal member 80a. Thereby, the sealing apparatus 1 can enclose the contents in the cup container H easily. Further, the contents in the cup container H can be prevented from spilling when the holder 23 is moved.

  Further, when the winding unit 32 is disposed below the supply unit 31, the winding motor 33 is disposed below, so that the center of gravity of the sealing device 1 can be lowered to improve the stability.

  According to the present invention, the present invention can be used in a transport device that transports a transported product and a sealing device including the transport device.
