A product receiving base 4 that is arranged to be openable and closable and receives the lowermost product A, a drive motor 5 as a drive source for generating a driving force for driving the regulating body 2 and the product receiving base 4, and extending substantially vertically. The drive shaft 6 rotated by the drive force of the drive motor 5, and the drive shaft 6 is attached to the drive shaft 6 and rotated, and the regulating body 2 is shown in a regulated posture (shown by phantom lines in FIG. 22B) and a non-regulated posture (see FIG. 22 (b) (shown by a solid line) and a support posture for supporting the product base 4 by being attached and rotated at the lower end of the drive shaft 6, that is, at a position below the control cam 7. (Indicated by the solid line in FIG. 22 (b) ) And a supporting cam 8 that is driven to open the opening 3 at the lower end of the product storage path 1 without supporting the product receiving base 4 (indicated by a phantom line in FIG. 22B). . And while restricting the fall of the 2nd goods A from the bottom in the goods storage path | route 1 by the control body 2, it is comprised so that the opening part 3 of the goods storage path | route 1 lower end may be opened and the goods A of the lowest end may be paid out. Yes.

  Specifically, the product dispensing apparatus 100 is provided vertically below the non-product storage space between adjacent product storage paths 1 (specifically, between the partition inner frames 15A that partition the inner surface side area of the product storage path 1). It is disposed in a long rectangular box-shaped housing frame 10. A pair of cradle support shafts 12 are arranged in a lateral posture substantially parallel to the left and right at the lower end of the housing frame 10, and the opening 3 at the lower end of the product storage path 1 is formed on the cradle support shaft 12. A substantially rectangular and flat product receiving base 4 that opens and closes and protrudes substantially horizontally into the product storage path 1 and closes the opening 3 so as to receive the product A and hangs down from the support supporting shaft 12. It is attached so as to be openable and closable over an open posture in which the opening 3 is opened.

  Further, a regulating body support shaft portion 14 is attached to the lower end portion of the elevating support member 13 slidably arranged in the casing frame 10 so as to be slidable up and down, and the regulation body support shaft portion 14 is rotated around the upper end portion thereof. The regulating body 2 that moves is provided (in this example, the regulation body supporting shaft portion 14 is integrally formed on the upper portion of the regulating body 2. It may be a separate structure. The restricting body 2 is stored in the non-product storage space and does not perform a restricting operation, and the lower side protrudes into the product storage path 1 so that the second product A is placed on the outer surface side of the product storage path 1. And a regulating posture that is sandwiched and held between the partition outer frame 15B and the partition outer frame 15B.

  A drive motor 5 and a speed reduction mechanism 11 (only the appearance is shown) serving as a drive force transmission unit that increases the torque of the drive force generated by the drive motor 5 are disposed in the upper part of the housing frame 10. The driving force of the driving motor 5 is transmitted to the upper end portion (driving force transmission point) of the driving shaft 6 disposed so as to extend vertically up and down at the central portion of the housing frame 10 in plan view. The A support cam 8 having a substantially semi-disc shape in plan view is fixed to the lower end portion of the housing frame 10 so as to rotate together with the drive shaft 6 in a horizontal plane. And in the state in which at least one part (substantially half) of the support cam 8 protrudes in the goods storage path | route 1, the goods base 4 is comprised by the support cam 8 so that it may be supported in a horizontal attitude | position. On the other hand, in the state where the support cam 8 is not in the product storage path 1, there is no support for the product base 4 from below, so that the product base 4 opens the opening 3 at the lower end of the product storage path 1. Become.

  A restriction cam 7 having a protrusion 7 a that is long in the vertical direction and protrudes to one side is fixed to a lower portion of the drive shaft 6. The protrusion 7a of the restriction cam 7 is disposed so as to be able to contact the restriction body 2 from the back side, and the restriction cam 7 is rotated so as to push up the restriction body 2 from the back side. 2 protrudes into the product storage path 1 and is configured to regulate the fall of the second product A from the bottom.

  When the product A is on standby for sale, as shown in FIG. 24 and the like, the support cam 8 rotated by the drive shaft 6 is disposed at a position straddling the product storage path 1 on both sides in plan view and supported by the support cam 8. The lowermost product A is received by the received product cradle 4 and the regulating body 2 is stored in the housing frame 10 (in the non-product storage space). Product A is held. On the other hand, when the product A is sold, the drive shaft 6 is rotated 90 degrees from the state shown in FIG. 24, and the restricting body 2 is pushed up by the restricting cam 7 as shown by the phantom line in FIG. 2 protrudes into the product storage path 1, and the fall of the second product A from the bottom in the product storage path 1 is restricted. At the same time, the support cam 8 is rotated so as to be disengaged from the product storage path 1 on one side, so that the product receiving table 4 is not supported. With the urging force of 24, the release posture is set, and as a result, the lowermost product A is paid out from the opening 3 at the lower end of the product storage path.

  In addition, on the cradle support shaft 12, the product cradle 4 has a sold-out detection lever 16 for detecting whether or not the product A is sold out, in a posture that overlaps the upper surface of the product cradle 4 and a posture that slightly separates upward. At the same time, it is rotatably attached and is urged in a direction away from the product receiving base 4 by urging means (not shown) (for example, a helical spring). Further, a notification for detecting the displacement of the position of the sold-out detection lever 16 (rotation operation for detecting sold-out) along one side (upper side in FIG. 23) extending vertically on the housing frame 10. The interlocking plate 17 is disposed vertically long, and the base end portion of the sold-out detection lever 16 is engageable with the lower end portion of the notification interlocking plate 17. The rotation operation (posture displacement) of the sold-out detection lever 16 is transmitted to the sold-out detection switch 18 disposed in the vicinity of the upper end portion (below the speed reduction mechanism 11). That is, when the product A is in the product storage path 1, the product A is placed on the sold-out detection lever 16 and the sold-out detection lever 16 is in close contact with the product receiving base 4. On the other hand, when the product A disappears from the product storage path 1, the sold-out detection lever 16 rotates upward to be separated from the product receiving base 4. Then, the rotation state (displacement) to the separation posture is transmitted to the upper sold-out detection switch 18 via the notification interlocking plate 17 and the detection part of the sold-out detection switch 18 is pressed. A sold-out product A is detected.

  The product cradle 4, the regulation body 2, the elevating support member 13, the sold-out detection lever 16, the notification interlocking plate 17, and the sold-out detection switch 18 are provided one by one for each product storage path 1 and notified. The interlocking plate 17 is disposed in a posture in which the back surfaces thereof are close to each other. On the other hand, only one drive motor 5, speed reduction mechanism 11, drive shaft 6, restriction cam 7, and support cam 8 are provided and shared for each pair of left and right product storage paths 1. Reference numeral 19 denotes a position adjustment knob for adjusting the positions of the elevating support member 13 and the regulating body 2 in the vertical direction.

JP 2004-94565 A Japanese Patent Application Laid-Open No. 2004-240846

  In conventional commodity dispensing apparatuses such as the commodity dispensing apparatus shown in FIGS. 22 to 24 and the commodity dispensing apparatuses disclosed in Patent Documents 1 and 2, the driving force of the drive motor 5 is long in the vertical direction. The drive shaft 6 is rotated by being transmitted to the upper end portion of the drive shaft 6, and this drive force is provided via the drive shaft 6 to the support cam 8 disposed at the lower end portion of the commodity dispensing device 100, and the support cam. 8 is transmitted to the upper restricting cam 7 and is transmitted by a drive shaft 6 over a long distance in the vertical direction. Therefore, it is easy to produce a torsional phase difference in the drive shaft 6, and the position control of the drive motor 5 has to be performed while taking into consideration the influence of the torsional phase difference. For this reason, it often takes time to adjust these control operations and the like, resulting in an increase in cost. There is also a problem that the positioning accuracy of the support cam 8 and the regulation cam 7 is low. Further, it is necessary to transmit the driving force satisfactorily over a long distance from the upper end portion to the lower end portion of the drive shaft 6, and the drive shaft 6 is thick and large in rigidity and long in order to minimize the amount of twist. This has led to an increase in manufacturing costs.

  Further, in the conventional product delivery device, since the drive motor 5 and the speed reduction mechanism 11 for driving the product cradle 4 and the regulating body 2 are arranged at the upper end portion of the housing frame 10, the product delivery The device 100 is also formed by extending the space for providing the drive motor 5 and the speed reduction mechanism 11 upward, and thus has a problem of requiring a large storage space long in the vertical direction. For this reason, for example, when the manufacturing place of the commodity dispensing apparatus 100 is separated from the assembly place (assembly factory) of the commodity dispensing apparatus 100 to the vending machine, the commodity dispensing apparatus 100 needs to be transported. Has a problem that the transportation cost is increased by the amount that the commodity dispensing apparatus 100 requires a large storage space.

  Further, the attitude displacement of the sold-out detection lever 16 disposed on the lower end side of the housing frame 10 (product dispensing device 100) is changed to the housing frame 10 (product) via the notification interlocking plate 17 extending vertically. Since the structure is such that it is transmitted to the sold-out detection switch 18 disposed on the upper end side of the payout device 100), the posture displacement of the sold-out detection lever 16 may not be transmitted well to the sold-out detection switch 18. That is, since the notification interlocking plate 17 that transmits the displacement of the attitude of the sold-out detection lever 16 has an elongated shape, it is easily deformed, causing poor transmission, or when incorporated in a vending machine. Condensed water generated in the product storage chamber of the vending machine flows between the back portions of the notification interlocking plates 17 disposed in close proximity to each other, and the notification interlocking plates 17 adhere to each other. There was a problem that the displacement of the attitude of the sold-out detection lever 16 could not be transmitted satisfactorily due to the poor movement of the interlocking plate 17.

  The present invention solves the above problems and problems, and can improve the positioning accuracy of the support cam and stopper cam by the drive shaft, minimize the storage space, and improve the reliability of the sold-out detection. An object of the present invention is to provide a product dispensing device for a vending machine capable of performing the above.

  In order to solve the above-described problems, a product dispensing device for a vending machine according to the present invention includes a regulation body that regulates the fall of the second product from the bottom in a product storage path for stacking and storing products, and a product storage path. A product pedestal arranged to open and close the opening at the lower end to receive the product at the lowermost end, a drive motor for generating a driving force for driving the regulating body and the product pedestal, and a drive motor extending substantially in the vertical direction A drive shaft that is rotated by the driving force, a restriction cam that is attached to the drive shaft and rotated to drive the restriction body in a restriction posture and a non-restriction posture, and a position below the restriction cam on the drive shaft A support cam that is mounted and rotated to drive the support posture for supporting the product cradle and an open posture that does not support the product cradle; By the body A product dispensing device for a vending machine that opens the opening at the bottom of the product storage path and pays out the product at the bottom end while regulating the product cradle, and the driving force from the drive motor on the drive shaft is transmitted The driving force transmission point is arranged at a position between the restriction cam and the support cam with respect to the vertical direction.

  With this configuration, the drive force transmission point at which the drive force of the drive motor is transmitted to the drive shaft is between the support cam and the regulating cam, so at least the support cam (or the support cam) from the drive force transmission point on the drive shaft. The distance to the mounting part of the cam and the control cam) can be shortened compared with the conventional one. As a result, the amount of twist of the drive shaft between these drive force transmission parts can be reduced, and at least supported by the drive shaft The positioning accuracy of the cam can be improved, the time for adjusting the control operation related to positioning can be reduced, and the drive shaft can be made thinner and shorter than before.

  Further, the present invention is provided with a driving force transmission portion that transmits the driving force of the driving motor to the driving shaft, and the driving motor and the driving force transmission portion are between the restriction cam and the support cam in the vertical direction. It is arranged in a region.

  With this configuration, the drive motor and the driving force transmission unit can be moved from the location where the support cam and the product receiving base are provided (the lower end portion of the product delivery device), which is a space that has conventionally been required for the function of the product delivery device. Since the product is housed in a region in the vertical direction up to the place where the regulation cam and the regulation body are disposed, the conventional product in which the storage space for the drive motor and the driving force transmission portion is provided above the regulation cam and the regulation body. Compared with the dispensing device, the space for the storage space of the conventional drive motor and the driving force transmission unit can be reduced, and as a result, the product dispensing device can be made compact.

  In addition, the present invention provides a sold-out detection lever that is freely displaceable between a posture placed on the upper surface of the product cradle and a posture separated from the upper surface of the product cradle, and a sell-out that detects the displacement of the posture of the sold-out detector lever. The sold-out detection switch is disposed in a region between the restriction cam and the support cam in the vertical direction.

  With this configuration, the sold-out detection lever and the sold-out detection switch can be arranged close to each other in the vertical direction, and the posture displacement of the sold-out detection lever can be transmitted directly or shortly to the sold-out detection switch. It can be transmitted indirectly through the component. Therefore, as compared with the conventional case where the attitude displacement of the sold-out detection lever is transmitted via an extremely long transmission part (for example, the above-described notification interlocking plate), the displacement of the sold-out detection lever is changed. Can be transmitted well.

  Further, the present invention is characterized in that the sold-out detection switch is constituted by a reed switch, and the displacement of the attitude of the sold-out detection lever is directly detected by the sold-out detection switch.

  With this configuration, the displacement of the sold-out detection lever can be transmitted to the sold-out detection switch satisfactorily, and by using a reed switch as a sold-out detection switch, There is an advantage that it is not affected by gas or humidity.

  Further, according to the present invention, a housing frame is disposed between a pair of product storage paths, and a regulation body is provided for each product storage path, and each regulation body is rotatably supported. The elevating support is disposed so as to be movable up and down with respect to the housing frame, and left and right position adjustment knobs for manually adjusting the vertical position of each elevating support are provided to be movable up and down. The region that can be moved up and down with respect to the body frame is arranged at a different position in the vertical direction so as not to overlap the left and right.

  With this configuration, even when the product dispensing device and its housing frame are thinned in the left-right direction, the position adjustment knob can be easily picked up, and the operability is improved. In other words, when the product dispensing device is thinned in the left-right direction, if the position adjustment knobs are arranged in pairs in the left-right direction, it is difficult to place fingers between the position adjustment knobs. Although it is difficult to pinch the adjustment knob and it may be difficult to operate, as described above, by shifting the area where the position adjustment knob is moved up and down, the horizontal dimension of the product dispensing device can be reduced. While the thickness can be reduced (compact), the position adjustment knobs are not adjacent to each other, making it easier to grip and improving the operability.

  According to the present invention, the drive force transmission point at which the drive force from the drive motor is transmitted to the drive shaft is disposed at a position between the restriction cam and the support cam in the vertical direction. The shaft can be shortened compared to the conventional one, and the amount of torsion of the drive shaft between the drive force transmission parts can be reduced to improve the positioning accuracy of at least the support cam (or support cam and regulating cam) by the drive shaft. Reliability can be improved. Further, it is possible to reduce the time for adjusting the control operation related to positioning, and accordingly, the cost can be reduced. Further, a thinner and shorter drive shaft can be used as the drive shaft, and this also realizes space saving and manufacturing cost reduction as compared with the conventional product dispensing apparatus.

  Further, the product dispensing device can be made more compact than the conventional one by disposing the drive motor and the drive force transmission portion in the region between the restriction cam and the support cam in the vertical direction. Thus, the storage space can be minimized, and the transportation cost can be reduced when the commodity dispensing device needs to be transported.

  Also, by arranging the sold-out detection switch in the region between the regulating cam and the support cam in the vertical direction, the sold-out detection lever and the sold-out detection switch are close to each other in the vertical direction. The displacement of the attitude of the sold-out detection lever can be transmitted well, and the reliability can be improved.

  Also, the displacement of the position of the sold-out detection lever can be transmitted directly, that is, satisfactorily by the sold-out detection switch. Moreover, by using a reed switch as a sold-out detection switch, It is possible to eliminate the influence of gas and humidity, and to further improve the reliability.

  In addition, by arranging the vertically movable area with respect to the housing frame of the left and right position adjustment knobs for manually adjusting the vertical position of the lifting support, by arranging the positions different in the vertical direction so as not to overlap with the left and right, Even when the product dispensing device and its housing frame are thinned in the left-right direction, the position adjustment knob can be easily picked up, and the operability is improved.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a product dispensing device for a vending machine according to an embodiment of the present invention will be described with reference to the drawings. Note that components having the same functions as those of the components of the conventional commodity dispensing apparatus 100 are denoted by the same reference numerals, and description thereof is omitted, and different points will be described.

FIG. 5 is an exploded perspective view of the drive unit (viewed from obliquely above), and FIG. 6 is the drive unit. FIG. 7A, FIG. 7B and FIG. 7C are an exploded perspective view of a speed reduction mechanism of the drive unit, a perspective view of a storage case, and an enlarged perspective view of a main part thereof. Figures 8 (a), 8 (b) and 8 (c) show the product receipt of the product delivery device. Is a side view, a perspective view, and a front view showing a state in which there is no product in the supporting posture, and FIGS. 9A and 9B show a state in which the product receiving base of the product dispensing device is in the supporting posture and the product is present. A perspective view and a front view, FIGS. 10A and 10B are a perspective view and a front view showing a state in which one of the product receiving units of the product dispensing device is in an open posture, and FIGS. FIGS. 12A and 12B are a perspective view of a sold-out detection lever and a product receiving base of the product dispensing device, and FIGS.

  As shown in FIGS. 1 to 6 and the like, in the commodity dispensing device 20, the drive motor 5, the speed reduction mechanism 11 as a drive force transmission unit that increases the torque of the drive force generated by the drive motor 5, A sold-out detection switch 18 for detecting the displacement of the posture of the detection lever 16 is disposed above the restriction cam 7 and the restriction body 2 (upper end portion of the housing 10) as in the conventional product dispensing device 100. Instead, it is disposed in a region between the restriction cam 7 and the support cam 8 in the vertical direction. The mounting position of the driving force transmission cam 30 of the driving shaft 6 that is a driving force transmission point for transmitting the driving force from the speed reduction mechanism 11 to the driving shaft 6 is also between the restriction cam 7 and the support cam 8. Arranged in position. The space between the regulation cam 7 and the support cam 8 receives the lowest product A from the product base 4 driven by the support cam 8, and from below by the regulation body 2 driven by the regulation cam 7. It is a space necessary for configuring the product dispensing device 20 (a necessary space provided corresponding to the size of the product A) in terms of the function of regulating the second product A.

  Specifically, in the non-commodity storage space between the product storage paths 1, a case portion 22 having a horizontally long box shape (see FIG. 5) is located slightly above the position where the sold-out detection lever 16 and the cradle support shaft 12 are provided. 5 and 6, the case portion 22 is provided with case portions 22 a to 22 c), and the drive motor 5 is mounted on the outer side of the housing frame 21 on one end portion of the case portion 22. Supported by the state. Further, a speed reduction mechanism 11 (see FIGS. 5 to 7) including a plurality of speed reduction gears 11 a to 11 e and the like is provided in a region of the case portion 22 on the side where the drive motor 5 is provided. The reduction gears 11 a to 11 e are meshed with the motor gear 5 a fixed to the motor shaft of the drive motor 5, and the final-stage reduction gear 11 e is fixed to the drive shaft 6. Is engaged. In addition, a reed switch as a sold-out detection switch 18 is disposed in a portion of the case portion 22 opposite to the side where the speed reduction mechanism 11 is disposed (see FIG. 1 and FIGS. 13 to 15). ). The reed switch used in this embodiment has a structure in which a contact portion is embedded in a small-diameter cylindrical space formed of glass or the like, and the contact portion is isolated from the outside air.

  As described above, the drive motor 5, the speed reduction mechanism 11, and the sold-out detection switch 18 are disposed in the region between the restriction cam 7 and the support cam 8 in the vertical direction. The storage space for the drive motor 5, the speed reduction mechanism 11, and the sold-out detection switch 18 above the restriction cam 7 and the restriction body 2, which are conventionally required as shown in FIG. 24, is no longer necessary. Thus, the housing frame 21 (as shown in FIG. 3, the housing frame 21 is composed of the housing frames 21 a to 21 c) also extends to the space in which the elevating support member 13 that rotatably supports the regulating body 2 is disposed. It is not necessary, and a smaller one than the conventional casing frame 10 is used in the vertical direction. For the same reason, the drive shaft 6 having a short vertical length is used.

  In the product dispensing device 20 of this embodiment, the sold-out detection lever 16 is not rotatably supported by the cradle support shaft 12 but is integrated with the tip of the product cradle 4. Centering on the formed pivot shaft 23 (see FIG. 11), the front end of the support shaft 23 is supported so as to be swingable upward from the base end side portion of the product support 4 with respect to the product support 4. Are arranged so as to overlap from above. In addition, a locking projection 16a that protrudes downward is formed in a part of the vicinity of the shaft support (referred to as the side of the tip) of the sold-out detection lever 16, and corresponds to the adjacent product storage path 1. A biasing spring 24 made of a tension spring is stretched between the engaging projections 16a of the pair of sold-out detection levers 16 provided as a pair. The biasing spring 24 causes the base end side (on the base in FIG. 1) of the sold-out detection lever 16 to be opposite to the front end side in a state where the product base 4 is in a substantially horizontal posture. The side in the vicinity of the support shaft 12) is urged in the direction of lifting upward from the product receiving tray 4.

  The sold-out detection lever 16 has a regulated base portion 16c, which is a part on the base end side thereof, having a recessed portion 22d formed in the end portion of the case portion 22 (FIG. 7 (c), FIG. 11, FIG. 12, 16 to 18), the product receiving base 4 is in the product receiving position, the regulated base 16c comes into contact with the top surface portion of the recess 22d, and the product receiving base 4 The separation posture is regulated so as to be within a predetermined range. Further, the sold-out detection lever 16 is formed with a regulated piece portion 16d following the regulated base portion 16c, and when the product receiving base 4 is in a suspended posture facing downward, the regulated piece portion 16d is formed as a case portion. 22 is in contact with the vicinity of the concave portion 22d (the restricting portion 22e) from the back surface side, and the position is regulated to a posture that is almost in close contact with the commodity receiving base 4 (a posture that does not spread outward).

  Further, as shown in FIGS. 11 and 12, a protrusion 16b is formed at one end in the width direction on the side of the base end of the sold-out detection lever 16, and the sold-out detection is detected at the protrusion 16b. A sold-out detection magnet 25 for detecting the displacement of the posture of the lever 16 is assembled. When the product A in the product storage path 1 is exhausted, as shown in FIG. 14, the sold-out detection magnet 25 of the sold-out detection lever 16 is in a state where the product receiving base 4 is in the horizontal posture. The close-up detection switch 18 is turned on and the product A is sold out. The urging spring 24 also has a function of applying an urging force for forcibly rotating the product receiving base 4 downward when the support cam 8 is rotated to a position where it is removed from the product storage path 1.

  Further, an extended portion 4b that extends slightly to the opposite side of the shaft support portion of the cradle support shaft 12 is integrally formed at the base end portion of the product cradle 4, and the extended portion 4b includes A cradle detection magnet 26 (see FIG. 11B, FIG. 15 etc.) for detecting the displacement of the posture is attached, and the product cradle 4 is displaced to a posture where it hangs down from the cradle support shaft 12. At this time, the cradle detection magnet 26 comes close to the sold-out detection switch 18 and the sold-out detection switch 18 is switched to the ON state, so that the displacement of the attitude of the product cradle 4 is also detected. That is, one sold-out detection switch 18 can detect both the detection of the sold-out state and the detection of the displacement of the attitude of the product receiving base 4, and the number of parts of the sold-out detection switch 18 is reduced. In addition, the cradle detection magnet 26 attached to the product cradle 4 itself and the sold-out detection switch 18 can detect that the product cradle 4 is actually displaced to an open posture depending on the cradle support shaft 12. It is like that. Therefore, if for some reason the product receiving base 4 does not switch to the above-described drooping open position even though the drive shaft 5 has been rotated to a predetermined position, the delivery failure of the product A is accompanied accordingly. Although it is highly probable to occur, it is possible to detect such a payout failure state (failure of switching to the drooping open posture), and the reliability is improved. Note that the cradle detection magnet 26 attached to the product cradle 4, the sellout detection magnet 25 attached to the sellout detection lever 16, and the sellout detection switch 18 are arranged on the left side of the product delivery device 20. The position (for example, the position in the depth direction) is shifted so as to be different from each other by the product receiving base 4 and the sold-out detection lever 16 provided on the right side, and can be detected individually. .

  In this embodiment, the lateral dimensions of the product dispensing device 20 are also reduced in thickness. Along with the reduction in thickness, a position adjustment knob 19 for manually raising and lowering the elevation support member 13 is provided as a knob. In order to make it easier, the lift support member 13 that supports the regulating body 2 is attached to a different position.

  This point will be described in detail. The lifting / lowering support member 13 is sandwiched from both sides by the housing frames 21b and 21c shown in FIG. 3 and extends vertically on both sides of the lifting / lowering support member 13 as shown in FIGS. 3 and 16-20. The integrally formed guide protrusion 13a is supported so as to be able to move up and down while being inserted and guided in a guide long hole 21d formed to extend vertically in the housing frames 21b and 21c. As shown in FIG. 19, a position adjustment knob 19 is integrally formed on one lifting support member 13 (13A), for example, so as to protrude elastically at the upper end of the right side, and the other lifting support member is also provided. 13 (13B), the position adjustment knob 19 is integrally formed in a posture protruding so as to be elastically deformable, for example, at the lower end of the right side. The housing frame 21 a is formed with a communication long hole 41 from which the position adjustment knob 19 protrudes to the side, and the engagement protrusion 19 a formed in the position adjustment knob 19 in the communication long hole 41. A plurality of concave portions 41a that can be engaged with each other are formed vertically. Then, while the engagement protrusion 19a of the position adjustment knob 19 is pressed with a finger so as to be detached from the recess 41a of the communication long hole 41, the position adjustment knob 19 is moved up and down to move the elevation support member 13 and the regulating body. The vertical position of 2 can be adjusted. In particular, in the housing frame 21a, the two communication long holes 41 are formed in regions where the vertical positions are different, and accordingly, the position adjustment knob 19 can also be adjusted in regions where the vertical positions are different. . Accordingly, when one of the position adjustment knobs 19 is held, the other position adjustment knobs 19 are not touched, so that each position adjustment knob 19 can be easily picked.

  In other words, when the product dispensing device 20 is thinned, if the position adjustment knobs 19 are arranged in pairs in the left-right direction as in the prior art, it is difficult for a finger to enter between the position adjustment knobs 19. Although it may be difficult to pinch the position adjustment knob 19 and it may be difficult to operate, as described above, the region in which the position adjustment knob 19 is moved up and down is shifted up and down. While the lateral dimension can be reduced in thickness (compact), the position adjustment knobs 19 are not adjacent to each other, making it easier to grip and improving the operability. It should be noted that this configuration is not necessary if the lateral dimension of the commodity dispensing device 20 is large to some extent.

  According to the above configuration, the drive motor 5 and the speed reduction mechanism 11 as the driving force transmission unit are provided with the support cam 8 and the product receiving base 4 that are functional spaces of the product dispensing device 20 in the vertical direction. Since the housing is housed in a region from the lower end portion of the product dispensing device 20 to the place where the restriction cam 7 and the restriction body 2 are disposed, the drive motor 5 and the deceleration are disposed above the restriction cam 7 and the restriction body 2. Compared with the conventional product dispensing device 100 in which the mechanism 11 is disposed, the space for the storage space of the conventional drive motor 5 and the speed reduction mechanism 11 can be reduced. It became possible to make it compact. Moreover, when it is necessary to transport the goods delivery apparatus 20, since a transport space also becomes small, a transportation cost can be reduced.

  Further, the mounting position (driving force transmission point) of the driving force transmission cam 30 on the driving shaft 6 that transmits the driving force of the driving motor 5 to the driving shaft 6 is defined between the support cam 8 and the regulating cam 7 on the driving shaft 6. Therefore, the distance from the drive force transmission point where the drive force transmission cam 30 is attached to the drive shaft 6 to the mounting portion of the support cam 8 and the regulation cam 7 can be shortened compared to the conventional one. As a result, the amount of twist of the drive shaft 6 between these drive force transmission portions can be reduced, and the positioning accuracy of the support cam 8 and the regulation cam 7 by the drive shaft 6 can be improved. As a result, the reliability can be improved along with the improvement of the positioning accuracy and the time for adjusting the control operation related to the positioning can be reduced, and the cost can be reduced accordingly. Further, the drive shaft 6 can be shorter than the conventional one (note that a thin one can be used as the drive shaft 6), and this also saves more space than the conventional product dispensing apparatus 100. And manufacturing costs can be reduced.

  Further, since the sold-out detection switch 18 is disposed in a region between the restriction cam 7 and the support cam 8 in the vertical direction, the sold-out detection lever 16 and the sold-out detection switch 18 are brought close to each other. Therefore, the displacement of the sold-out detection lever 16 can be directly transmitted to the sold-out detection switch 18, so that the sold-out detection operation can be reliably detected and the reliability can be improved.

  Therefore, the sold-out detection operation can be transmitted better than in the conventional case where the displacement of the sold-out detection lever 16 is transmitted via the notification interlocking plate 17 having a very long dimension. Although not shown, the attitude displacement of the sold-out detection lever 16 may be indirectly transmitted to the sold-out detection switch 18 via a short-length displacement transmission component. The reliability can be improved as much as the length can be shortened. However, it is a matter of course that it is more reliable to directly transmit the attitude displacement of the sold-out detection lever 16 to the sold-out detection switch 18, and in this case, no transmission parts are required, so the number of parts can be reduced. There is also an advantage that the manufacturing cost can be reduced.

  Further, by using a reed switch as the sold-out detection switch 18, it is possible to eliminate the influence of atmospheric gas and humidity at the installation location of the vending machine, and to further improve the reliability.

  In other words, when a micro switch is used as the sold-out detection switch 18, depending on the installation location of the vending machine, the contact may deteriorate due to the influence of gas, humidity, etc. contained in the atmosphere of the installation location. In this case, the sold-out state of the product A cannot be detected satisfactorily, and the reliability is lowered. On the other hand, since the reed switch is arranged in a space where the contacts are sealed (for example, a closed space in the glass), it is not affected by atmospheric gas or humidity at the installation location of the vending machine, Good reliability is maintained.

  Moreover, in the said embodiment, since it comprised so that both the detection of a sold-out state and the detection of the attitude | position displacement of the goods stand 4 could be detected with one sold-out detection switch 18, the detection switch 18 was separately provided. Compared with the case where it is provided, the number of parts can be reduced, and this can also reduce the manufacturing cost.

  In addition, the cradle detection magnet 26 attached to the product cradle 4 itself and the sold-out detection switch 18 can detect that the product cradle 4 is actually displaced in a posture of hanging from the cradle support shaft 12. Therefore, when the product cradle 4 does not switch to the above-mentioned hanging position even though the drive shaft 5 has been rotated to a predetermined position for some reason, It is possible to detect a poor switching state to the posture. That is, when such a failure to switch the product receiving base 4 to the hanging posture occurs, it is highly likely that a defective delivery of the product A has occurred. When the selling-out detection switch 18 detects that a switching failure has occurred, it is possible to warn that there is a high possibility of a defective delivery of the product A, thereby improving reliability.

  In the present embodiment, the manufacturing location of the product dispensing device 20 is different from the assembly location to the vending machine, and when the product is transported, the product dispensing device 20 in the transportation as shown in FIG. In a state where only the support cam 8 is not attached to the lower end portion of the drive shaft 6, the merchandise receiving tray 4 and the sold-out detection lever 16 are folded in a posture extending downward along the housing frame 21 and conveyed. In addition, when the product cradle 4 is in a suspended position, the regulated piece 16d formed on the sold-out detection lever 16 comes into contact with the regulating portion 22e of the case portion 22 from the back side. The sold-out detection lever 16 is regulated to be in a close contact with the product receiving base 4. Therefore, in this state, the sold-out detection lever 16 and the product receiving base 4 of the product dispensing device 20 do not protrude in the lateral direction, and the accommodation space can be minimized, and as a result, the transportation cost can be further reduced. Can do.
