As shown in FIG. 4, the right end portion of the connecting shaft 31 enters a hollow portion 291a of the swing shaft portion 291 of the product take-out door 29. As shown in FIG.

Here, the swing shaft portion 291 is a shaft portion formed by curving the upper end portion of the product delivery door 29 in a curled shape, and the left and right end portions thereof are the upper end portions of the left and right side edges of the product delivery port 28 . pivoted on. The central axis of the swing shaft portion 291 serves as the swing shaft of the product take-out door 29 . A notch 291b is formed in a part of the swing shaft portion 291, and the portion of the connecting shaft 31 inserted into the swing shaft portion 291 that is exposed from the notch 291b is connected to the connecting member 33 so that the article can be taken out. It is connected to door 29 .

That is, the right end portion of the connecting shaft 31 is inserted into the hollow portion 291 a of the swing shaft portion 291 in such a manner that the central axis of the connecting shaft 31 coincides with the central axis of the swing shaft portion 291 , and a part of the right end portion is inserted into the connecting member 33 . , and rotates around the central axis integrally with the swing shaft portion 291 (the product delivery door 29).

A portion of the left end portion of the connecting shaft 31 is cut to form a D-cut portion 311 having a D-shaped longitudinal section. The D cut portion 311 is formed such that its maximum width is smaller than the outer diameter of the other portion of the connecting shaft 31 . A cam 34 is attached to the D cut portion 311 .

The cam 34 is made of, for example, a resin material or a metal material, and is configured by integrally molding a cam base portion 341 and a cam acting portion 342 . The components of the cam 34 will be described according to the direction shown in FIG.

The cam base 341 is a plate-like portion extending along the front-rear direction. A mounting hole 341 a is formed in the cam base 341 . The attachment hole 341a has a shape that matches the outer shape of the D-cut portion 311, and allows the D-cut portion 311 to pass therethrough.

As shown in FIG.

FIG. 5 is an exploded perspective view showing the transmission shaft 32 shown in FIG. 3 and its peripheral structure. The transmission shaft 32 exemplified here is a cylindrical member made of, for example, a metal material or a resin material, and extends along the left-right direction. The transmission shaft 32 is provided rotatably around the central axis so as to pass through a through hole 351 of a mechanism body 35 made of, for example, sheet metal.

A transmission gear 321 is attached to the left end portion of such transmission shaft 32 . The transmission gear 321 has transmission teeth formed on its outer periphery, and these transmission teeth mesh with the linkage teeth on the outer periphery of a linkage gear 352 rotatably provided on the mechanism body 35 . The linking gear 352 is linked to the motor 36 as a drive source via a torque limiter 353 . The motor 36 is installed in the mechanism main body 35 and is driven to rotate forward and backward in accordance with a command given from an electrically connected control section 40 .

Such a link gear 352 rotates counterclockwise around the central axis when the motor 36 is driven to rotate forward, while rotating from the right when the motor 36 is driven to rotate in the reverse direction. As you can see, it rotates clockwise around the central axis. As a result, the transmission shaft 32 rotates clockwise around the central axis when the motor 36 rotates in the forward direction, and rotates clockwise when the motor 36 rotates in the reverse direction. It rotates counterclockwise around the central axis.

The transmission shaft 32 has an inner diameter larger than the maximum width of the D-cut portion 311 of the connecting shaft 31 and smaller than the outer diameter of the portion of the connecting shaft 31 other than the D-cut portion 311 . A pin mounting hole 322 is formed in the side portion of the transmission shaft 32 in a manner orthogonal to the direction of the central axis (horizontal direction). ing.

Such a transmission shaft 32 is formed in such a manner that, in a standby state in which the motor 36 stops driving, the action pin 37 extends vertically and protrudes rightward from the mechanism main body 35 . The action pin 37 is in contact with the stopper piece 354 .

6, the D cut portion 311 of the connecting shaft 31 to which the cam 34 is attached relatively enters the right end portion of the transmission shaft 32, so that the central axis of the transmission shaft 32 becomes the connecting shaft. 31 are connected in a manner that coincides with the central axis. Since the inner diameter of the transmission shaft 32 is larger than the maximum width of the D-cut portion 311 as described above, the transmission shaft 32 is connected to the connecting shaft 31 while allowing the connecting shaft 31 to rotate about the central axis. ing. In this case, the action recess 342a of the cam 34 is arranged on the rear side of the action pin 37, as shown in FIG.

In the product outlet structure having the configuration described above, the connecting shaft 31 and the transmission shaft 32 are connected. 31, and the action recess 342a of the cam 34 is arranged on the rear side of the action pin 37 when the product delivery door 29 closes the product delivery port 28. As shown in 7, the user manually swings the product take-out door 29 forward to allow the product take-out port 28 to be opened. In the opening/closing mechanism 30, when the user releases the grip of the product delivery door 29, the product delivery door 29 swings rearward under its own weight, and the product delivery port 28 is closed. allow.

In other words, the opening/closing mechanism 30 permits the product outlet 28 to be opened and closed by manually swinging the product outlet door 29 in a normal state in which the motor 36 is stopped.

On the other hand, in the product outlet structure, when the motor 36 rotates in the forward direction for a predetermined time (for example, about 3 to 5 seconds) in response to a command from the control unit 40, the transmission shaft 32 becomes the center axis when viewed from the right. Rotate clockwise around. As a result, as shown in FIG. 8, the action pin 37 abuts against and presses the action concave portion 342a, so that the opening/closing mechanism 30 moves the article unloading door 29 forward at a predetermined angle, as shown in FIG. It is swung (for example, about 150°) to open the commodity outlet 28 . After that, the control unit 40 stops the motor 36 for a predetermined time (for example, about 5 seconds), so that the opening/closing mechanism 30 keeps the product outlet 28 open.

When the opening/closing mechanism 30 receives a command from the control unit 40 and the motor 36 reversely rotates for a predetermined time (for example, about 3 to 5 seconds), the transmission shaft 32 rotates around the central axis as viewed from the right side. Rotate counterclockwise. As a result, the pressing force from the action pin 37 to the action recess 342a is released, and the product take-out door 29 is swung rearward. After that, when the action pin 37 comes into contact with the stopper piece 354 , the motor 36 is stopped by a command given from the control section 40 , so that the open/close mechanism section 30 closes the commodity outlet 28 .

That is, when the motor 36 is driven (forward rotation driving and reverse rotation driving), the opening/closing mechanism 30 swings the product ejection door 29 to open and close the product ejection port 28 .

Here, the presence or absence of a drive command to the motor 36 by the control unit 40 is determined by a prior setting input by input means such as a remote controller. More specifically, when it is desired to manually swing the product take-out door 29, it is necessary to set in advance using a remote controller or the like so that the control unit 40 does not give a drive command or a drive stop command to the motor 36. good. Further, when it is desired to automatically swing the article take-out door 29, it is necessary to use a remote controller or the like to set in advance such that a drive command, a drive stop command, or the like is given from the control section 40 to the motor 36 at a predetermined timing. Just do it.

As described above, according to the product outlet structure according to the first embodiment of the present invention, the product outlet 28 is opened and closed by manually swinging the product outlet door 29 in the opening/closing mechanism 30 in the normal state. On the other hand, when the built-in motor 36 is driven, the product take-out door 29 is swung to open and close the product take-out port 28. Therefore, by swinging the product take-out door 29 automatically or manually, Convenience can be improved.

Further, according to the product outlet structure, the opening/closing mechanism 30 is connected to the pivot shaft portion 291 of the product outlet door 29 in such a manner that the central axes of the opening and closing mechanism portion 30 and the pivot shaft portion 291 coincide with each other. a connecting shaft 31 that rotates integrally with the cam 34; and a cam 34 that is attached to the connecting shaft 31 and has a cam action portion 342 that extends in the left-right direction and has a V-shaped action concave portion 342a formed therein. , is provided rotatably around the central axis according to the drive of the motor 36, and is connected in such a manner that the connecting shaft 31 is rotatable around the central axis in a state where the central axes of the connecting shaft 31 and each other are aligned. A shaft 32 and an action pin 37 provided on the transmission shaft 32 are provided. When the transmission shaft 32 rotates, the action pin 37 abuts against the action concave portion 342a of the cam action portion 342 to press the cam 34. Therefore, it is possible to prevent the action pin 37 from being displaced in the left-right direction when the action pin 37 presses the cam 34, and it is also possible to absorb the dimensional error.

Moreover, since the action pin 37 contacts the cam 34 (the action concave portion 342a) after the transmission shaft 32 has rotated to some extent, the action pin 37 is disengaged when the product delivery door 29 closes the product delivery port 28. 37 does not come into contact with the cam 34, and it is possible to prevent the action pin 37 from pressing the cam 34 due to dimensional error or the like and the commodity outlet 28 from being constantly opened.

As shown in FIG. 13, a product delivery door 29' is provided at the upper end of each of the right and left side edges of the product delivery port 28'. The product delivery door 29' is for opening and closing the product delivery port 28', and opens the product delivery port 28' when swinging forward, and opens when swinging backward. It closes the article outlet 28'. The commodity outlet door 29' closes the commodity outlet 28' when only its own weight acts.

As shown in FIG. 14, an opening/closing mechanism 50 is provided at the left end of the product outlet 28'. The opening/closing mechanism 50 constitutes a product outlet structure together with the product outlet 28' and the product outlet door 29', and includes a transmission shaft 51. As shown in FIG.

The transmission shaft 51 is a substantially cylindrical member made of, for example, a metal material or a resin material, and extends in the left-right direction. The transmission shaft 51 is provided rotatably around the central axis in such a manner as to pass through a through hole 521 of the mechanism main body 52 made of sheet metal or the like.

A transmission gear 511 is attached to the left end portion of such a transmission shaft 51 . The transmission gear 511 has transmission teeth formed on its outer periphery, and these transmission teeth mesh with the linkage teeth on the outer periphery of a linkage gear 522 rotatably provided on the mechanism body 52 . The link gear 522 is linked to the motor 53 as a drive source via a torque limiter 523 . The motor 53 is installed in the mechanism main body 52 and is driven to rotate forward and backward according to commands given from the electrically connected control section 41 .

When the motor 53 rotates forward, the link gear 522 rotates counterclockwise around the center axis as seen from the right side. As you can see, it rotates clockwise around the central axis. As a result, the transmission shaft 51 rotates clockwise around the center axis when the motor 53 rotates in the forward direction, and rotates clockwise when the motor 53 rotates in the reverse direction. It rotates counterclockwise around the central axis.

As shown in FIGS. 15 and 16, such a transmission shaft 51 is formed with a D-cut portion 512 having a D-shaped longitudinal section by partially cutting the right end portion. The D cut portion 512 is formed such that its maximum width is smaller than the outer diameter of the other portion of the transmission shaft 51 . The cam 54 is attached to the D-cut portion 512 while entering the hollow portion 291c of the swing shaft portion 291' of the product delivery door 29'.

Here, the swinging shaft portion 291' is a shaft portion formed by curving the upper end portion of the product delivery door 29' in a curled shape, and the left and right end portions of the swing shaft portion 291' correspond to the left and right side edges of the product delivery port 28'. is pivoted on the upper end of the The central axis of the swing shaft portion 291' serves as the swing shaft of the product take-out door 29'. Such a swing shaft portion 291' is formed to have an inner diameter larger than the maximum diameter of the D-cut portion 512, and a notch 291d is formed in a part thereof.

That is, the D-cut portion 512 of the transmission shaft 51 is inserted into the hollow portion 291c of the swing shaft portion 291' so that the center axis of the transmission shaft 51 coincides with the center axis of the swing shaft portion 291'.

The cam 54 is made of, for example, a resin material, a metal material, or the like, and is configured by integrally molding a cam base portion 541 and a cam protrusion portion 542 . The cam base 541 is a disk-shaped portion having a thickness that allows it to enter the notch 291d of the product delivery door 29'. A mounting hole 541 a is formed in the cam base 541 . The mounting hole 541a has a shape conforming to the outer shape of the D-cut portion 512 and allows the D-cut portion 512 to pass therethrough. The cam protrusion 542 is a flat plate-like portion that extends leftward from a part of the periphery of the left surface of the cam base 541 .

With the cam base 541 inserted into the notch 291d of the product delivery door 29', the cam 54 is passed through the mounting hole 541a relatively to the D cut portion 512 of the transmission shaft 51 from the left side. It is attached to the D cut portion 512 . The cam 54 swings integrally with the transmission shaft 51 about the central axis of the transmission shaft 51, that is, the central axis of the swing shaft portion 291'.

When the product delivery door 29' closes the product delivery port 28', the cam 54 has a posture in which the cam projection 542 is arranged above the swing shaft 291' as shown in FIG. It will be.

A pin mounting hole 513 is formed in the transmission shaft 51 so as to be orthogonal to the direction of the central axis (horizontal direction), and an action pin 55 is mounted so as to penetrate the pin mounting hole 513 .

Such a transmission shaft 51 is formed so that, in a standby state in which the motor 53 is stopped, the action pin 55 extends vertically and protrudes rightward from the mechanism main body 52 . The action pin 55 is in contact with the stopper piece 524 .

In the article outlet structure having the configuration described above, although the D-cut portion 512 of the transmission shaft 51 enters the hollow portion 291c of the swing shaft portion 291', the maximum diameter of the D-cut portion 512 does not swing. The inner diameter of the hollow portion 291c of the shaft portion 291' is smaller than that of the hollow portion 291c. As shown in FIG. 17, the reference numeral 50 allows the user to manually swing the product take-out door 29' forward to open the product take-out port 28'. In the open/close mechanism 50, when the user releases the product delivery door 29', the product delivery door 29' swings backward under its own weight to close the product delivery port 28'. allow to be

In other words, the opening/closing mechanism 50 permits the opening and closing of the article outlet 28' by manually swinging the article outlet door 29' in the normal state in which the motor 53 is stopped.

On the other hand, in the product outlet structure, when the motor 53 rotates in the forward direction for a predetermined time (for example, about 3 to 5 seconds) in response to a command from the control unit 41, the transmission shaft 51 becomes the central axis when viewed from the right. Rotate clockwise around. As a result, as shown in FIGS. 18 and 19, the cam protrusion 542 abuts and presses a part of the product take-out door 29', and the opening/closing mechanism 50 operates as shown in FIG. The door 29' is swung forward at a predetermined angle (for example, about 150°) to open the article outlet 28'. After that, the control unit 41 stops the motor 53 for a predetermined time (for example, about 5 seconds), so that the opening/closing mechanism 50 keeps the product outlet 28' open.

When the motor 53 is reversely rotated for a predetermined time (for example, about 3 to 5 seconds) in response to a command from the control unit 41, the opening/closing mechanism unit 50 rotates the transmission shaft 51 around the center axis as viewed from the right side. Rotate counterclockwise. As a result, the pressing force from the cam protrusion 542 to a part of the article unloading door 29' is released, and the article unloading door 29' is swung rearward. After that, when the action pin 55 comes into contact with the stopper piece 524, the motor 53 is stopped by a command given from the control section 41, so that the opening/closing mechanism section 50 closes the commodity outlet 28'.

In other words, when the motor 53 is driven (forward rotation driving and reverse rotation driving), the opening/closing mechanism 50 swings the product take-out door 29' to open and close the product take-out port 28'.

Here, the presence or absence of a drive command to the motor 53 by the control unit 41 is determined by a prior setting input by input means such as a remote controller. More specifically, when it is desired to manually swing the product take-out door 29', it is necessary to use a remote controller or the like to set in advance such that the control unit 41 does not give a drive command or a drive stop command to the motor 53. Just do it. Further, when it is desired to automatically swing the product take-out door 29', a remote controller or the like is used in advance so that the controller 41 can give a drive command, a drive stop command, or the like to the motor 53 at a predetermined timing. do it.

As described above, according to the article outlet structure of the second embodiment of the present invention, the opening/closing mechanism 50 is operated such that the article outlet door 29' is manually swung to open the article outlet 28' in the normal state. On the other hand, when the built-in motor 53 is driven, the product take-out door 29' is swung to open and close the product take-out port 28'. Convenience can be improved by rocking.

<Other Modifications>
In the product outlet structures of the first and second embodiments described above, there is no means for detecting the swinging of the product outlet doors 29, 29', that is, the opening and closing of the product outlets 28, 28'. However, as shown in FIG. 21, an opening/closing detection mechanism 60 may be provided in the article outlet structure of the present invention. The configuration of the open/close detection mechanism 60 will be described below.

When the detection switch 612 is turned off and electrically connected to the control unit 40, an off signal is sent to the control unit 40. is sent. Although the details will be described later, the controller 40 judges that the commodity outlet 28 is closed when an OFF signal is sent from the detector 61, while an ON signal is sent from the detector 61. If so, it is determined that the commodity outlet 28 has been opened.

The lever portion 62 is configured including a first lever 621 and a second lever 622, as shown in FIGS. Each component of the lever portion 62 will be described according to the directions shown in FIGS. 22 and 23. FIG.

The first lever 621 is made of, for example, a metal material, and includes a first lever base portion 6211 and a first lever acting portion 6212 .

The first lever base 6211 is a plate-like member extending along the front-rear direction. A lever through-hole 6211 a is formed in the first lever base 6211 . The lever through-hole 6211 a is formed to have the same shape and size as the hollow portion 291 a of the swing shaft portion 291 of the product take-out door 29 . That is, the lever through-hole 6211a has a substantially circular shape formed linearly in such a manner that parts of the portions facing each other are parallel to each other.

The first lever acting portion 6212 is a tongue-shaped portion extending leftward from a portion of the rear end portion of the first lever base portion 6211 .

The second lever 622 is formed by, for example, bending a long plate-like body made of a metal material or the like, and includes a second lever base portion 6221 and a second lever acting portion 6222 . there is

The second lever base 6221 is a horizontally extending portion that extends in the front-rear direction, and a cylindrical portion 6221a that is curved in a curled shape to form a cylindrical shape is formed at the front end portion of the second lever base 6221 . The inner diameter of the cylindrical portion 6221a of the second lever base portion 6221 is formed to be larger than the outer diameter of the swing shaft portion 291 of the product take-out door 29 and smaller than the minimum width of the first lever base portion 6211. It is formed to be

The second lever acting portion 6222 is an elongated portion that extends downward from the rear end portion of the second lever base portion 6221 and then gradually slopes forward as it goes downward. The extended end of the second lever acting portion 6222 is bent downward at a right angle.

A lever shaft portion 63 passes through the first lever 621 and the second lever 622 from the right side. The lever shaft portion 63 is a substantially cylindrical member extending along the left-right direction. An insertion portion 631 is formed at the left end portion of the lever shaft portion 63 . The insertion portion 631 has an outer shape and outer dimensions that match the lever through-hole 6211a and the hollow portion 291a of the swing shaft portion 291, and a part of the portions facing each other is formed flat.

The insertion portion 631 of the lever shaft portion 63 passes through the lever through-hole 6211a of the first lever 621 from right to left, and the cylindrical portion 6221a of the second lever base portion 6221 of the second lever 622 passes through the right-hand side. The first lever 621 and the first lever 621 and the first lever 621 and the The second lever 622 is rotatable around the central axis of the lever shaft portion 63 .

Here, since the lever through-hole 6211 a of the first lever 621 has the same shape and size as the hollow portion 291 a of the swing shaft portion 291 , the first lever 621 can move the product through the lever shaft portion 63 . It is provided integrally with the take-out door 29 so as to be swingable around the central axis of the lever shaft portion 63 (the central axis of the swing shaft portion 291). On the other hand, since the inner diameter of the tubular portion 6221 a of the second lever 622 is larger than the outer diameter of the swing shaft portion 291 , the right end of the swing shaft portion 291 is positioned between the product delivery door 29 and the first lever 621 .

As shown in FIG. 24, in a state in which the product take-out door 29 closes the product take-out port 28, the first lever 621 swinging together with the product take-out door 29 is moved by the first lever acting portion 6212. The second lever base portion 6221 of the second lever 622 is pressed, and the second lever 622 swings backward. When the second lever 622 swings backward in this way, the second lever acting portion 6222 abuts on the arm 613 to swing the arm 613 so as to approach the detection main body 611 and press the arm 613 . As a result, the detection switch 612 is put in the recessed state. When the detection switch 612 is in the retracted state, the detection section 61 sends an OFF signal to the control section 40, and the control section 40 determines that the commodity outlet 28 is closed.

On the other hand, when the product take-out door 29 swings forward manually or automatically, the first lever 621 swings together with the product take-out door 29 around the central axis. As a result, the pressing force from the first lever 621 is released, and the reaction force from the detection switch 612 and the arm 613 acts on the second lever 622 that has been pressed by the first lever acting portion 6212 of the first lever 621. 25, the second lever action portion 6222 moves away from the arm 613, thereby detecting the movement of the arm 613. As shown in FIG. Switch 612 is in the out state. When the detection switch 612 is thus in the out state, the detection section 61 sends an ON signal to the control section 40, and the control section 40 determines that the article outlet 28 is opened.

After that, when the product take-out door 29 swings forward as shown in FIG. stay free by breaking away from

In such an opening/closing detection mechanism 60, the first lever 621 swings integrally with the product delivery door 29, and when the first lever 621 is pressed, the detection switch 612 is brought into the retracted state. When the pressing force from the first lever 621 is released, the second lever 622 becomes free and causes the detection switch 612 to be in the open state. In addition, an adjustment margin for the detection unit 61 can be secured, and an increase in the size of the entire mechanism can be suppressed.
