The mounting portion 31 is attached to the rack bottom plate 10 a (see FIG. 1) which constitutes the product rack 10.

  FIG. 4 is a perspective view showing the spiral unit 40 shown in FIG. As shown in FIG. 4, the spiral unit 40 includes a drive mechanism 41 and a spiral 50.

  As shown also in FIG. 5, the drive mechanism 41 is configured to include an output gear 43 and a transmission member 44 inside a housing 42 in which two drive cases 42a and 42b are combined to form a front and rear pair. .

  The output gear 43 has a substantially annular shape although not shown in the figure, and an aspect in which the output tooth portion 43a formed in the inner peripheral edge portion is exposed from the inner surface of the through hole 421 formed in the housing 42 At the inside of the case 42. Here, the through hole 421 extends in the front-rear direction at a substantially central portion of the housing 42. The output gear 43 is housed in the housing 42 such that the central axis coincides with the central axis of the through hole 421 of the housing 42.

  The output gear 43 has an outer peripheral output toothed portion (not shown) formed on an outer peripheral edge portion linked with a motor (not shown), not shown, housed in the inside of the housing 42 through an interlocking gear (not shown). By transmitting the driving force from the motor, the driving source is configured to rotate around its own central axis, for example, clockwise when viewed from the front. The rotation of the output gear 43 is detected by a carry-out detection switch (not shown) provided inside the housing 42.

  The transmission member 44 is configured by integrally forming a transmission base 441, a first transmission shaft 442, and a second transmission shaft 443. The transmission base 441 has a substantially disc shape, and a through hole (not shown) is formed in a central portion thereof.

  The first transmission shaft portion 442 is a cylindrical portion formed to protrude rearward from the rear surface of the transmission base 441. The first transmission shaft portion 442 has an outer diameter that can be inserted into the through hole 421 of the housing 42, and the inside thereof communicates with the through hole portion. Further, at the rear end portion of the first transmission shaft portion 442, meshing pieces 442a are formed at portions facing each other. A meshing projection 442 b is formed at each end of the meshing piece 442 a and meshes with a part of the output tooth portion 43 a of the output gear 43. Thus, the transmission member 44 can rotate integrally with the output gear 43 about its own central axis, that is, can rotate clockwise as viewed from the front. Here, the central axis of the transmission member 44 coincides with the central axis of the through hole 421 of the housing 42 and the central axis of the output gear 43.

  The second transmission shaft portion 443 is formed to project forward from the front surface of the transmission base portion 441, and the inside thereof communicates with the through hole. That is, the inside of the second transmission shaft portion 443 constitutes the hollow portion 444 together with the through hole portion of the transmission base portion 441 and the inside of the first transmission shaft portion 442. The central axis of the second transmission shaft portion 443 coincides with the central axis of the first transmission shaft portion 442 and coincides with the central axis of the transmission member 44.

  The front end edge portion of such a second transmission shaft portion 443 is notched in part (a part on the lower side), so that the front end surface of the second transmission shaft portion 443 is located at the rearmost position. Between the first end face 443a, the second end face 443b located at the front, and the first end face 443a and the second end face 443b, the first end face 443a is moved from the first end face 443a toward the second end face 443b A third end surface portion 443c that is inclined forward is continuously formed.

  As shown in FIGS. 4 and 5, in the standby state, in the transmission member 44, the first end surface portion 443 a of the second transmission shaft portion 443 is located below.

  The spiral 50 is formed by spirally winding, for example, a metal rod body along the front-rear direction (the extending direction of the column case 30), as shown in FIGS. 2 and 4. is there. The rear end portion 51 of the spiral 50 is supported by the annular joint member 45 in such a manner that the central axis coincides with the central axis of the transmission member 44 (the central axis of the output gear 43).

  Here, while the joint member 45 holds the rear end portion 51a of the spiral 50 toward the central portion of itself, the rear end portion 51 of the spiral 50 continuous to the rear end portion 51a winds the outer peripheral surface of itself. The spiral 50 is supported in a rotating manner. Such a coupling member 45 is engaged with the transmission member 44 by elastically deforming a locking claw 445 formed on the transmission base 441 of the transmission member 44, and is detachable from the transmission member 44. It is. That is, the joint member 45 is detachable from the transmission member 44 by a so-called snap fit, and constitutes a transmission unit together with the transmission member 44.

  The spiral 50 is connected to the transmission member 44 via the joint member 45 and can be integrally rotated with the transmission member 44. Then, the spiral 50 rotates around the central axis (clockwise as viewed from the front) to carry out the goods constrained between the pitches toward the front gradually while being restrained between the foremost pitches. To deliver the goods.

  By the way, although the carry-out detection switch detects the rotation of the output gear 43, the output gear 43 and the transmission member 44 are integrally rotated, and the spiral 50 is further integrally rotated with the transmission member 44. As a result, the carry-out detection switch detects the rotation of the spiral 50.

  6 is a perspective view showing the base unit 60 shown in FIG. 2 as viewed from the lower right side. As also shown in FIG. 6, the base unit 60 is configured to include a base 61, a slider 62, a sell-off actuator 63, and a sell-off detection switch 64.

  The base 61 is, for example, an elongated member whose longitudinal direction is a longitudinal direction formed by bending a sheet metal or the like. As shown in FIG. 7, such a base 61 is configured by integrally forming a base portion 611, a base front end portion 612, and a base rear end portion 613.

  The base portion 611 is a flat portion extending in the front-rear direction, and the left and right side portions thereof are bent downward. The base portion 611 has a length slightly smaller in the front-rear direction than the spiral 50, and a rectangular long hole 611a whose longitudinal direction is the longitudinal direction is formed at the front end portion.

  The base front end portion 612 is a portion provided continuously to the front end portion of the base base 611. The base front end portion 612 includes a front end inclined portion 612 a, a front surface configuration portion 612 b, and a front end locking portion 612 c.

  The front end inclined portion 612 a is inclined downward gradually toward the front from the front end portion of the base portion 611. The front face configuration portion 612b extends downward from the extension end of the front end inclined portion 612a, extends rearward, and extends upward.

  The front end locking portion 612c extends rearward from the extending end of the front surface portion 612b, and has a locking projection 614 projecting downward in a substantially central region in the left-right direction of the extending end. It is formed.

  The base rear end portion 613 is a portion provided continuously to the rear end portion of the base portion 611. The base rear end portion 613 includes a rear end fastening portion 613a, an upper support piece 613b, a right side support piece 613c, and a left side support piece 613d (see FIG. 2).

  The rear end fastening portion 613a is a portion that extends upward from the central portion of the extension end of the portion that gradually inclines upward as going rearward from the rear end portion 51a of the base portion 611. A fastening hole 615 is formed in the rear end fastening portion 613a.

  The upper support piece 613b is formed in such a manner as to project rearward from the upper end edge of the rear end fastening portion 613a. The right side support piece 613c is formed in such a manner as to project rearward from the right end edge of the rear end fastening portion 613a. The left support piece 613d is formed in such a manner as to project rearward from the left end edge of the rear end fastening portion 613a.

  The base 61 having such a configuration extends along the front-rear direction (the extending direction of the column case 30) in a manner to penetrate the inside of the spiral 50, and the locking projection 614 of the base front end 612 is the column case The base front end portion 612 is locked and supported by the column case 30 by entering the locking hole 33 formed in the front end portion of the base 30.

  In the base 61, the upper support piece 613b, the right support piece 613c, and the left support piece 613d of the base rear end portion 613 face the outer peripheral surface of the second transmission shaft portion 443 of the transmission member 44, A fastening pin 70 (see FIG. 2) inserted through the fastening hole 615 of the rear end fastening portion 613a is screwed into a support member (not shown) inserted through the hollow portion 444 of the transmission member 44.

  Thereby, the base 61 can place the goods restrained between each pitch of the spiral 50 on the upper surface of the base base 611.

  The upper support piece 613b of the base rear end portion 613 of the base 61 is positioned forward of the rear end portion 51a of the spiral 50 when the spiral 50 is in the standby state before rotation as shown in FIG. And overlap with the rear end portion 51a as viewed from the front.

  A restricting member 71 is detachably provided on the base 61. As shown in FIG. 9, the restriction member 71 is a long member whose longitudinal direction is the longitudinal direction, and is formed by bending a steel plate. In this restriction member 71, a bottom wall portion 711 mountable on the upper surface of the base portion 611 and an upper wall portion 712 extending upward from the right end edge of the bottom wall portion 711 are integrally formed. Is configured. An engagement portion 713 extending downward is formed at the front end portion of the upper wall portion 712, and an engagement hole 713a is formed in the engagement portion 713. At the rear end of the bottom wall portion 711 is formed an engaging piece 714 cut and raised so as to protrude downward.

  Such a restricting member 71 has an engagement hole 713 a inserted through an engagement long hole 611 b formed in the rear end 51 of the base base 611 and is formed at the front end of the right side 611 c of the base base 611. It is attached to the right side part 611c of the base base 611 by making the engagement pin 72 which penetrates the engagement hole 713a approach into the matching hole 611d and screwing it. At this time, the bottom wall portion 711 is placed on the upper surface of the base portion 611, and the upper wall portion 712 extends upward continuously from the right side portion 611c of the base portion 611. The upward extension length of the upper wall 712 is such that the upper end portion of the upper wall 712 does not interfere with the spiral 50.

  The restricting member 71 is attached to the right side portion 611 c of the base portion 611 because the spiral 50 rotates clockwise as viewed from the front. That is, among the left and right end portions of the base 61, one end portion on which a portion of the spiral 50 located above the base 61 is displaced downward by the rotation of the spiral 50 is the right end portion. Therefore, it is attached to the right side portion 611c. Therefore, when the spiral 50 rotates counterclockwise as viewed from the front, a part of the spiral 50 located above the base 61 among the left and right ends of the base 61 rotates the spiral 50. Thus, since the one end that is the side that is displaced downward is the left end, the restriction member is attached to the left side. When the restricting member is attached to the left side, the restricting member is symmetrical to the restricting member 71 in the lateral direction.

  The slider 62 is disposed on the lower surface side of the base portion 611 so as to be movable in the front-rear direction with respect to the base 61 by a slider mounting member (not shown) attached to the base 61. The slider 62 has a slider base 621, a slider rear end 622, and a slider front end 623 integrally formed.

  The slider base 621 is a long rod-like portion whose longitudinal direction is the longitudinal direction. The slider rear end portion 622 is a portion provided continuously to the rear end portion 51 a of the slider base 621, and is a portion extending downward from the rear end portion of the slider base 621.

  The slider front end portion 623 is a portion provided continuously with the front end portion of the slider base 621 as shown in FIG. 10, from the front end of the left extended portion 624 extending leftward from the front end portion of the slider base 621 It extends so as to project forward. The front end surface 623a of the slider front end portion 623 is an inclined surface which gradually inclines upward as it goes forward.

  The slider 62 having such a configuration is always urged rearward by the slider spring 625 provided between the left extending portion 624 which is the rear end portion of the slider front end portion 623 and the slider mounting member on the frontmost side. ing. As a result, the slider 62 contacts the lower portion of the front end face (the first end face 443a, the second end face 443b, and the third end face 443c) of the second transmission shaft 443 of the transmission member 44 with the slider rear end 622 (See Figure 6).

  As described above, in the standby state, the transmission member 44 has the first end surface portion 443a of the second transmission shaft portion 443 located at the lower side. Therefore, in the standby state, the slider rear end portion 622 is the first end surface portion 443a. I am in contact with Here, since the first end face portion 443a is located at the rearmost position relative to the second end face portion 443b and the third end face portion 443c, the slider 62 in which the slider rear end 622 contacts the first end face portion 443a is It has moved to the rearmost side.

  The sold-out actuator 63 is provided on the lower side of the base portion 611 on the front side of the slider base 621. As shown in FIG. 11, the sold-out actuator 63 is configured to include a shaft-like portion 631, a contact portion 632, an inclined extension portion 633, and an action portion 634.

  The shaft portion 631 is a portion that protrudes in the left-right direction, and is axially supported by an actuator mounting member 66 attached to the base portion 611. As a result, the sold-out actuator 63 can swing around the central axis of the shaft portion 631.

  The contact portion 632 is a portion extending along the radial outer direction of the shaft portion 631 and is opposed to the slider front end portion 623. The inclined extension portion 633 is an elongated portion formed in such a manner as to be gradually inclined upward toward the front than the contact portion 632. The inclined extension portion 633 can pass through the long hole 611 a formed in the base portion 611. The action portion 634 is a curved portion formed in such a manner as to project rightward on the lower side than the shaft-like portion 631.

  Such an off-the-shelf actuator 63 is provided in such a manner as to wind the shaft portion 631 and by the actuator spring 635 interposed between itself and the actuator mounting member 66, the inclined extension portion 633 always points upward. It is energized.

  The sold-out detection switch 64 is supported by the actuator mounting member 66 so as to be located on the right side of the sold-out actuator 63, as shown in FIG. The sold-out detection switch 64 is provided with a sold-out contact 641. This sold-out contact 641 is biased by biasing means (not shown) and its standby position is determined. The sold-out detection switch 64 detects that “the product is present” when the sold-out contact 641 is in the standby position without being pressed at all. On the other hand, when the sold-out contact 641 is displaced against the biasing force of the biasing means by being pressed by the action portion 634 of the sold-out actuator 63, the sold-out detection switch 64 Detect That is, the sold-out detection switch 64 is disposed at a position where the sold-out contact 641 can abut on the action portion 634 of the sold-out actuator 63.

  The wiring connected to the sold-out detection switch 64 is wound by a support member inserted through the hollow portion 444 of the transmission member 44 so as to pass through the hollow portion 444.

  In such a base unit 60, as shown in FIG. 2, when the product is not restrained between at least the frontmost pitches of the spirals 50, as shown in FIG. The inclined extension portion 633 passes through the long hole 611 a and moves forward to the upper area of the base 61. As described above, when the sold-out actuator 63 is in the advanced position, the sold-out contact 641 is displaced against the urging force of the urging means by the action portion 634 pressing the sold-out contact 641.

  On the other hand, when the product is restrained between the foremost pitches, as shown in FIG. 14, the sold-out actuator 63 is urged to the urging force of the actuator spring 635 by the inclined extension portion 633 being pressed by the product W. It moves retrogressively from the above-mentioned advance posture. As described above, the sold-out actuator 63 moves backward from the advanced position, so that the sold-out contact 641 becomes free and is urged only by the biasing unit without being pressed at all, and becomes the standby position.

  By the way, in the product storage device 20, the spiral 50 is optimally selected from a plurality of types having different pitches according to the size of the product to be stored. On the other hand, the sold-out actuator 63 and the sold-out detection switch 64 are common regardless of the type of the spiral 50 applied.

  Therefore, the installation position of the sold-out actuator 63 is a point where it is possible to press the commodity between the foremost pitches of the applicable spirals 50, although the length between the pitches is the largest.

  Therefore, when the spiral 50 having a relatively small length between pitches is used, the sell-off actuator 63 is not only between the foremost pitches of the spirals 50 but also between the foremost second pitches or the foremost three pitches. The inclined extension portion 633 may be pressed by the product constrained between the second pitches to move backward from the advancing position. That is, the sold-out actuator 63 may move backward from the advancing position even when the product is not constrained between the foremost pitches of the spiral 50 and the product is restrained between the foremost second pitches.

  The goods storage apparatus 20 which has the above structures can pay out the goods (foremost goods) restrained between the foremost pitches as follows.

  When the user selects a product of the product storage device 20 through the product selection means, and gives a dispensing command by performing subtraction processing by turning the electronic money recording medium to a predetermined communication area, the product storage The device 20 is driven by a motor so that the output gear 43 and the transmission member 44 rotate clockwise about the central axis when viewed from the front. That is, the spiral 50 also rotates clockwise.

  As described above, when the transmission member 44 rotates in the clockwise direction as viewed from the front together with the output gear 43, the slider rear end 622 which has been in contact with the first end surface 443a of the second transmission shaft 443 in the standby state After being in contact with the third end face portion 443 c of the second transmission shaft portion 443, it is in contact with the second end face portion 443 b. As a result, the slider 62 moves forward against the biasing force of the slider spring 625.

  When the slider 62 moves forward, as shown in FIG. 15, the slider front end portion 623 is positioned above the abutment portion 632 of the sell-off actuator 63, and the sell-off actuator 63 is forced to move backward. Hold it.

  Then, the spiral 50 is rotated by the rotation of the output gear 43 and the transmission member 44 by the drive of the motor, whereby the product constrained between the pitches of the spiral 50 is carried forward toward the front and restrained between the foremost pitches. Goods are paid out toward the front.

  After that, the motor is driven when the slider rear end 622 which was in sliding contact with the second end face 443b of the second transmission shaft 443 contacts the third end face 443c and the output gear 43 and the transmission member 44 make one rotation. It stops and the delivery of the first item is finished. Then, as shown in FIG. 16, the slider 62 is biased by the slider spring 625 to move rearward, and the slider front end portion 623 separates from the sell-off actuator 63.

  As a result, as shown in FIG. 14, the sold-out actuator 63 is in a posture of retreating movement from the advancing posture when the inclined extension portion 633 is pressed by the product W restrained between the pitches of the front region, as shown in FIG. As shown, when the product is not restrained between the pitches in the front area, it is in the advancing position.

  By the way, the goods paid out from the spiral 50 are received by the conveyance tray 12 and conveyed by the conveyance tray 12 to the vicinity of the goods outlet 15a. Such a product is then ready for removal through the product outlet 15a.

  As described above, in the product storage device 20 according to the embodiment of the present invention, since the restricting member 71 is attached to the right side portion 611 c of the base portion 611, a flexible triangular pole shape such as a sandwich is formed. And when the product is constrained between the pitches of the spiral 50 in a reclining posture with the rectangular surface on the lower side, even if the spiral 50 rotates clockwise as viewed from the front, It is possible to prevent the product from moving toward the right by the continuously upward extending upper wall portion 712, and to prevent a part of the product from being pinched between the spiral 50 and the base 61. Therefore, it is possible to well store and carry out the product which is in the form of a flexible triangular prism and whose rectangular surface is the lower surface and is restrained in the sideways posture.

  In particular, since the restricting member 71 is detachably provided to the base 61, the restricting member 71 can be removed to store the product when the product does not have a flexible triangular prism shape. The versatility can be good.

  According to the product storage device 20, since the joint member 45 for supporting the rear end 51 of the spiral 50 constitutes the drive mechanism 41 and is detachable from the transmission member 44 attached to the drive source, the joint member By separating 45 from the transmission member 44, the spiral 50 can be replaced while leaving the transmission member 44, and the replacement work of the spiral 50 can be simplified.

  The upper support piece 613b of the base 61 is located on the front side of the rear end portion 51a of the spiral 50 when the spiral 50 is in the standby state before rotation, and viewed from the front with the rear end portion 51a. Since the upper support piece 613b abuts on the rear end portion 51a of the spiral 50 even when the spiral 50 is pulled forward, the spiral 50 is prevented from being pulled forward and being removed because it overlaps. Can. That is, when the replacement work of the spiral 50 is performed, the upper support piece 613 b is pressed downward to elastically deform while separating the joint member 45 from the transmission member 44, so that the back of the upper support piece 613 b and the spiral 50 is The spiral 50 can be removed by releasing the overlapping with the end portion 51a as viewed from the front. Accordingly, unintended detachment of the spiral 50 can be prevented while simplifying the replacement work of the spiral 50.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the above-described embodiment, the presence / absence of the product is detected by moving back and forth from the advancing posture or the advancing posture with the sold-out actuator 63, but in the present invention, for example, an optical sensor It may be detected using

  In the embodiment described above, the joint member 45 is detachably attached to the transmission member 44 by, for example, a snap fit, but in the present invention, the connection between the joint member and the transmission member may be detachable. For example, the form is not particularly limited.
