  A product carry-out device including the motor drive unit 7 having such a configuration has been filed as Japanese Patent Application No. 2013-236105 (Japanese Patent Laid-Open No. 2015-95235) by the applicant of the present application.

  The sold-out detection switch 8 (8A) is a micro switch that is locked and fixed to a wiring cover WC (see FIG. 2) mounted on the substrate 1. The sold-out detection switch 8 (8A) is disposed so that the contact of the microswitch contacts the sold-out detection piece 23 (23A) provided on the lower pedal member 2 (2A), and the lower pedal member 2 (2A) is It is configured to detect a state in which one of the adjacent product storage passages 183 and 183 protrudes to the maximum opening degree (the other). That is, the lower pedal member 2 (2A) is always urged toward the protruding position by the elastic urging force of the torsion coil spring 30 (30A), and protrudes into the product storage passages 183 and 183 without holding the product. And when the product falls on the lower pedal member 2 (2A) protruding to the maximum opening, the product is rotated in a direction to retract from the product storage passage 183, and then the bearing base of the lower pedal member 2 (2A) 26 (26A), the front end of the locking projection 27 (27A) contacts the lowered lower link pin 4 (4A) to lock the lower pedal member 2 (2A) in the protruding position protruding into the product storage passage 183; The opening degree of the lower pedal member 2 (2A) in the locked state is configured to be smaller than the maximum opening degree. Therefore, when the lower pedal member 2 (2A) protrudes to the maximum opening degree, the sold-out detection switch 8 (8A) is configured so that the sold-out detection piece 23 (23A) provided on the lower pedal member 2 (2A) is in contact with the microswitch. A product is dropped on the lower pedal member 2 (2A) that protrudes to the maximum opening degree, and the lower pedal member 2 (2A) rotates in a direction to retract from the product storage passages 183 and 183. After that, the sold-out detection piece 23 (23A) provided on the lower pedal member 2 (2A) is separated from the contact of the microswitch and is turned off before being locked. The control unit that processes the signal from the sold-out detection switch 8 (8A) performs a process of determining “sold out” when the ON signal from the sold-out detection switch 8 (8A) continues for a predetermined time.

  The cover member 90 is attached to the back surface of the substrate 1 so as to cover the motor drive unit 7 attached to the substrate 1, and the plate surface of the cover member 90 is a part of the product storage passage 183 similarly to the plate surface of the substrate 1.

As shown in FIG. 2B, a hook-shaped engagement piece 91 is formed at the upper end of the cover member 90 so as to cover the upper flange 1 c of the substrate 1, and is inserted into the slit 101 a of the back plate 101 at the lower end of the cover member 90. A claw piece 92 is formed. The claw piece 92 is provided with a step so as to be lowered by one step from the plate surface of the cover member 90. The cover member 90 is mounted by engaging the engaging piece 91 so as to hold the upper flange 1c of the substrate 1 while inserting the claw piece 92 into the slit 101a of the back plate 101.

  The operation of the commodity carry-out device 10 of the vending machine having such a configuration will be described with reference to FIGS. FIG. 9 is a side sectional view of the product unloading device 10 before loading the product, FIGS. 10 and 11 show the operation of the product unloading device, and FIG. 10 and FIG. 11A are side views of the product unloading device 10. Sectional drawing (b) is a perspective view of essential parts of the first carry-out mechanism and the second carry-out mechanism in which the lower pedal member 2 (2A) is omitted, and FIGS. 9, 10 (a) and 11 (a). Is a cross section on the opening 11 side of the flange 11b of the opening 11 of the substrate 1 (on the right side of the flange 11b in FIG. 4). In the following description, one of the product storage passages 183 and 183 adjacent to the front and rear of the lower pedal member 2 of the first carry-out mechanism of the product carry-out device 10 is indicated by reference numeral “183”. The other product storage passage is indicated by reference numeral “183A”. Reference numeral 290 denotes an outlet adjusting plate disposed opposite to the product carry-out device 2 (2A) and the product storage passage 183 (183A).

  As shown in FIG. 9, in the product unloading device 10, in the state before the product is loaded, the lower pedal member 2 (2A) projects into the adjacent product storage passage 183 (183A), and the upper pedal member 3 is in the product storage passage. Evacuated from 183 (183A). In this case, the cam projection 731 of the output gear 73 of the motor drive unit 7 is located at the uppermost position (see FIG. 8A). Further, the carrier switch 74 pressing piece provided on the back surface of the output gear 73 is located at the uppermost position, and the carrier switch 74 is in the ON state. As a result, the motor 71 is stopped, and the distal end portion 752 (752A) of the link lever 75 (75A) is at a position spaced downward from the connecting portion 61 (61A) of the link member 60 (60A). For this reason, the link member 60 (60A) is in a state of being lowered by the urging force of the return spring 64 (64A). Further, the lower pedal member 2 is in a protruding position opened to the maximum opening degree in the product storage passage 183 (183A) by the urging force of the torsion coil spring 30. The lower link pin 4 (4A) supported by the lowered link member 60 (60A) is positioned on the turning trajectory line at the tip of the locking projection 27 (27A) of the lower pedal member 2 (2A). Thus, in the state where the lower pedal member 2 (2A) is opened to the maximum opening, the sold-out detection switch 8 (8A) is turned on. On the other hand, the upper pedal member 3 has edges of the pair of left and right shaft support portions 22 (22A) of the lower pedal member 2 (2A) in which the locking pieces 34 protruding outward from the shaft support portions 31 at both ends are opened to the maximum opening degree. The product is positioned at the retracted position from the product storage passage 183 (183A) by contacting the portion (see FIG. 9).

  In such a standby state, the first loaded product falls to the lower pedal member 2 (2A) which is opened to the maximum opening and is in the protruding position. When the product falls, the lower pedal member 2 (2A) rotates toward the retracted position. When the tip of the locking projection 27 (27A) of the lower pedal member 2 (2A) contacts the lower link pin 4 (4A) by this rotation, the lower pedal member 2 holds the product and opens smaller than the maximum opening. The product that is locked in a state of protruding into the product storage passage 183 (183A) and held on the lower pedal member 2 (2A) becomes the product with the highest sales order (sales product G1). Thus, when the lower pedal member 2 (2A) is locked in a state where the lower pedal member 2 (2A) protrudes into the product storage passage 183 (183A) with an opening smaller than the maximum opening, the sold-out detection switch 8 (8A) is turned off. Become. The next loaded product is stacked on the sales product G1 held by the lower pedal member 2 (2A) to become the next sales product G2, and the product (G3) subsequently loaded is the next sales product G2. They are stacked one after another (see FIG. 10).

  When a sales instruction based on the operation of the product selection button is given (for example, when the product stored in the product storage passage 183 is selected and the first carry-out mechanism is activated), the motor built in the motor drive unit 7 71 is driven to rotate forward, and the output gear 73 rotates in the counterclockwise direction in FIG. 8 via the gear transmission mechanism 72. When the output gear 73 rotates counterclockwise, the pressing piece provided on the back surface of the output gear 73 is detached from the contact of the carrier switch 74, the carrier switch 74 is turned off, and then the carrier switch 74 is turned on. The motor 71 is driven to rotate in the forward direction (that is, until the output gear 73 rotates once). When the cam protrusion 731 comes into contact with the base end portion 751 of the link lever 75 from above by the rotation of the output gear 73 in the counterclockwise direction, the link lever 75 rotates in the clockwise direction in FIG. As the link lever 75 rotates in the clockwise direction, the tip 752 abuts against the connecting portion 61 of the link member 60 and the link member 60 rises against the urging force of the return spring 64 (FIG. 10). (See also (b)). While the cam protrusion 731 is in sliding contact with the base end portion 461a of the link lever 75, the link member 60 is held in a raised state.

  As the link member 60 is raised, the lower link pin 4 coupled to the link member 60 is also raised, and the lower pedal member 2 locked at the protruding position to the product storage passage 183 is released by the lower link pin 4. Is done. Accordingly, the lower pedal member 2 starts to move from the product storage passage 183 toward the retracted position in response to the load of the product. When the lower pedal member 2 moves to the retracted position retracted from the product storage passage 183, the sold product G1 passes through the lower pedal member 2 and is carried out downward. When the sale product G1 passes through the lower pedal member 2, the lower pedal member 2 starts to move toward the protruding position by the urging force of the torsion coil spring 30, and then enters the product storage passage 183 in a state of opening to the maximum opening. Return to the protruding position.

  The upper link pin 5 rises simultaneously with the lower link pin 4 that rises as the link member 60 rises, and the upper link pin 5 rises when it comes into contact with the inclined surface 331 of the engagement wall 33 of the upper pedal member 3. The pedal member 3 is pushed out from the standby position toward a projecting position that projects into the product storage passage 183. When the upper link pin 5 rises to a position facing the stopper surface 332 formed following the inclined surface 331 of the engaging wall 33 of the upper pedal member 3, the upper link pin 5 comes into contact with the stopper surface 332 and the product of the upper pedal member 3 The movement to the retracted position for retracting from the storage passage 183 is restricted. Then, the upper pedal member 3 that has moved to the protruding position protruding into the product storage passage 183 contacts and holds the lower part of the next sale product G2 that moves downward when the sale product G1 is carried out, and the next sale product G2. Is restricted from moving downward.

  As the link member 60 is raised, the lower pedal member 2 is unlocked by the lower link pin 5 to allow the lower pedal member 2 to move to the retracted position and pay out the merchandise G1, while the upper pedal member 3 is retracted. The operation of moving the product from the position to the protruding position and holding the next sale product G2 is executed during a predetermined time during which the cam protrusion 731 of the output gear 73 is in sliding contact with the base end portion 751 of the link lever 75.

  When the contact between the cam projection 731 and the base end portion 751 of the link lever 75 is released by the rotation of the output gear 73, the link member 60 is lowered by the urging force of the return spring 64. As the link member 60 is lowered, the upper link pin 5 and the lower link pin 4 supported by the link member 60 are lowered. When the upper link pin 5 in contact with the stopper surface 332 of the upper pedal member 3 is lowered, the upper pedal member 3 is pressed by the next sale product G2 and moves toward the retreat position where it is retracted from the product storage passage 183. Due to the movement of the upper pedal member 3 to the retracted position, the next sale product G2 held by the upper pedal member 3 starts to move downward. On the other hand, the lower link pin 4 descends to a position where it intersects the turning trajectory line of the arc-shaped locking projection 25 of the lower pedal member 2 that has returned to the protruding position. Thereafter, when the next sale product G2 falls on the lower pedal member 2 opened to the maximum opening, the lower pedal member 2 moves toward the retracted position, and the arc-shaped locking protrusion 25 of the lower pedal member 2 is lowered. When it comes into contact with the lower link pin 4, the next sale product G2 is locked in the protruding position while being held as a sale product. Thereafter, when the cam protrusion 731 returns to the standby position by the rotation of the output gear 73, the contact of the carrier switch 74 is pressed by the pressing piece, and the carrier switch 74 is turned on. As a result, the driving of the motor 71 is stopped and the standby state is restored.

  Note that after the output gear 73 is rotated counterclockwise, the cam projection 731 and the base end portion 751 of the link lever 75 are released from contact with each other, and then the cam projection 731 of the output gear 73 is brought into the standby state. On the way back, the cam projection 731 contacts the base end 751A of the link lever 75A, but the locking piece 753A made of an elastic member is elastically deformed to allow the link lever 75A to rotate, thereby moving the cam projection 731. Return to the return position without being blocked. The link lever 75A returns to the standby posture shown in FIG. 8A by the action of the locking piece 753A when the cam projection 731 passes.

  When a sales command based on the operation of the product selection button is given (for example, when the product stored in the product storage passage 183A is selected and the second carry-out mechanism is activated), the motor built in the motor drive unit 7 71 is reversely driven, and the output gear 73 rotates in the clockwise direction in FIG. 8 via the gear transmission mechanism 72. When the output gear 73 rotates in the clockwise direction, the pressing piece provided on the back surface of the output gear 73 is detached from the contact of the carrier switch 74, the carrier switch 74 is turned off, and then the carrier switch 74 is turned on. The motor 71 is driven in reverse until it becomes (that is, a period until the output gear 73 rotates once). Thereafter, the operation of the link mechanism 6A that supports the lower pedal member 2A, the upper pedal member 3, the lower link pin 4A, and the upper link pin 5A of the second carry-out mechanism is as follows. 3, since the operation is the same as that of the link mechanism 6 that supports the lower link pin 4 and the upper link pin 5, a duplicate description is omitted.

  The product carry-out apparatus having such a configuration can be applied to a slant-type product storage rack (hereinafter referred to as a “slan track”), which will be described with reference to FIGS. FIG. 12 is a side view of the main part of the slan track, FIG. 13 is a perspective view of the slan track of FIG. 12 as viewed obliquely from above, and FIG. 14 is an enlarged view of the main part showing the mounting state of the product carrying device mounted on the slan track. .

  As shown in FIGS. 12 and 13, the slan track 300 includes a pair of left and right rack side plates 310 on which a plurality of product storage shelves 320 are arranged in the horizontal direction and arranged in multiple stages in the vertical direction. . The pair of left and right rack side plates 310 includes a front rack side plate 310F and a rear rack side plate 310R. The product storage shelf 320 extends across the front rack side plate 310F and the rear rack side plate 310R in such a manner that the front side as the product input port SL is high and the rear side as the product carry-out port is inclined with a predetermined gradient. The front rack side plate 310F and the rear rack side plate 310R are installed. The product storage shelf 320 is a pair of left and right (the left top shown in FIG. 13) laid across the first shelf 321 and the second shelf 322 respectively laid on the front rack side plate 310F and the rear rack side plate 310R. The guide 323L and the right side top guide 323R). The product storage shelf 320 corresponds to a top tray in a serpentine product storage rack and a pair of left and right top guides that are laid on the top tray and adjusts the passage width. A plurality of commodities are arranged in a line and arranged in a line in the front-rear direction to form a product storage passage (product column) 380, and the product storage shelves 320 are arranged in multiple upper and lower stages. Ten product columns are formed.

  And in the rear end part of the commodity storage shelf 320 in each stage, a protruding position that protrudes into the carry-out passage 340 extending in the vertical direction formed by the passage forming member 350 attached to the rear rack side plate 310R, and falling A posture control plate 330 is provided that can be rotated between a retraction position that is pushed open by a product to be retreated and retracted from the carry-out passage 340 and that is biased so as to protrude toward the carry-out passage 340. The attitude control plate 330 is attached to the rear end of the second shelf plate 322. A plurality of slan tracks 300 configured in this way are arranged in parallel in the left-right direction in the commodity storage of the main body cabinet 100 (see FIG. 15) formed as a heat-insulating housing. The configuration of such a slan track is the same as that of a vending machine product storage rack known from Japanese Patent Application No. 2011-58381 (Japanese Patent Laid-Open No. 2012-194797) filed by the present applicant.

  The slan track 300 shown in FIG. 12 to FIG. 14 is different from the conventional device in that the conventional slan track has individual product carry-out devices corresponding to the respective product storage shelves. In this embodiment, among the product storage shelves 320 arranged in the upper and lower stages, the product carry-out device 10 shown in FIGS. 1 to 8 is arranged corresponding to every other product storage shelf 320 from the top. An opening 323 (see FIG. 13) is formed in the second shelf 322 so that the lower pedal member 2 and the upper pedal member 3 of the first carry-out mechanism of the product carry-out device 10 can be moved in and out. It is a point that has been. In this product carry-out device 10, the lower pedal member 2 of the first carry-out mechanism 2 and the lower pedal member 2A of the second carry-out mechanism are located on the rear side of the product storage passage 380, and the upper pedal member 3 (the upper pedal member 3 is 12 to 14 are attached to the slan track 300 in such a manner that they are retracted to the retracted position and cannot be seen because they are hidden behind the flange of the second shelf 322). Then, the lower pedal member 2 and the upper pedal member 3 of the first carry-out mechanism alternately appear and disappear in one product storage passage 380 (for example, the upper product storage passage 380) of the product storage passages 380 and 380 adjacent to each other in the vertical direction. The lower pedal member 2A and the upper pedal member 3 of the second carry-out mechanism alternately appear in the other product storage passage 380 (for example, the lower product storage passage 380A) of the product storage passages 380 and 380 adjacent to each other in the vertical direction. The products stored in the product storage passages 380 and 380A adjacent vertically are carried out one by one.

  The product carry-out device 10 is attached to the slan track 300 by engaging the front and rear pin members P, P (see FIG. 14) installed on the rear rack side plate 310R. That is, as shown in FIG. 14, the front pin member P is tilted from the lower side of the second shelf 322 so that the plane of the substrate 1 of the commodity carry-out device 10 is aligned with the plate surface of the second shelf 322. The engagement portion 1aa, 1bb formed on the upper part of the left and right flanges 1a, 1b of the substrate 1 by bringing the substrate 1 of the product carry-out device 10 closer from the rear, and the hook-like engagement portion provided on the upper flange 1c of the substrate 1 The product carry-out device 10 is moved forward so that the front pin member P is sandwiched between 1 cc and 1 cc. When the horizontal portion of the hook-like engaging portion 1cc (a portion flush with the surface of the upper flange 1c of the substrate 1) comes into contact with the front pin member P by the forward movement of the product carry-out device 10, the lower end of the substrate 1 is moved. Since it comes to be located in front of the rear pin member P, the substrate 1 is rotated upward with the front pin member P as a fulcrum. Here, in a state where the hook-shaped holder 9 provided at the lower end of the substrate 1 is elastically deformed so as to open backward, the substrate 1 is rotated upward so that the hook 9a of the holder 9 gets over the rear pin member P. In addition, the substrate 1 is slid backward. In this case, the substrate 1 is slid rearward so that the semicircular engagement grooves 1dd formed at the lower ends of the left and right flanges 1a, 1b of the substrate 1 are fitted into the rear pin member P. When the semicircular portion of the engagement groove 1dd is fitted into the rear pin member P by sliding the substrate 1 rearward, the hook 9a of the holder 9 is restored and the rear pin member P between the engagement groove 1dd is restored. Pinch. In this state, the front pin member P is placed between the engaging portions 1aa, 1bb formed on the upper left and right flanges 1a, 1b of the substrate 1 and the hook-shaped engaging portion 1cc provided on the upper flange 1c of the substrate 1. It is pinched and locked. That is, the dimensions of the engaging portions 1aa, 1bb formed on the upper left and right flanges 1a, 1b of the substrate 1 and the hook-shaped engaging portions 1cc provided on the upper flange 1c of the substrate 1 sandwich the front pin member P. Even when the board 1 is slid rearward in the state and fitted into the semicircular engaging groove 1dd formed at the lower ends of the left and right flanges 1a and 1b of the board 1 on the rear pin member P, Since the length of the engagement is determined so that the engagement is not disengaged, the engagement portions 1aa, 1bb formed on the upper portions of the left and right flanges 1a, 1b of the substrate 1 and the hook-shaped engagement portions provided on the upper flange 1c of the substrate 1 1 cc is locked to the front pin member P without being disengaged from the front pin member P.

  In this way, among the product storage shelves 320 arranged in the upper and lower multi-stages of the slan track 300, they are mounted on the front and rear pin members P and P corresponding to every other product storage shelf 320 from the top. The lower pedal member 2 and the upper pedal member 3 constituting the first carry-out mechanism of the product carry-out device 10 can be moved into and out of the upper product storage passage 380 through the opening 323 provided in the second shelf 322, Further, the lower pedal member 2 </ b> A and the upper pedal member 3 constituting the second carry-out mechanism can freely move in and out of the lower product storage passage 380 from the back side of the substrate 1. In addition, since the carrying-out operation | movement of the goods accommodated in the adjacent goods storage channel | path 380,380A by the goods carrying-out apparatus 10 is the same as what was shown in FIG.10 and FIG.12 mentioned above, the description is omitted here.
