Patent No. 4396041 Patent No. 3632332

  By the way, instead of directly detecting the temperature of the product stored in the product storage rack 180, the inside temperature sensor T detects air in the storage storing the product and indirectly detects the temperature of the product. It is generally configured. And, in order to detect that the commodity to be dispensed by the commodity unloading device 200 is surely adjusted to the desired sales temperature, it is attached to the outlet adjusting plate 210 disposed opposite to the commodity unloading device 200. In this case, the wiring of the in-chamber temperature sensor T is also the same as the wiring of the electrical components (solenoid and sold-out detection switch) of the commodity unloading device 200, and the temperature of the commodity drops due to the selling operation of the commodity unloading device 200 In order to prevent contact with the wiring of the sensor T and breaking the posture and causing product clogging, it is led to one side of the pair of left and right rack side plates 181, 181 (for example, the rack side plate 181 on the left in front view) A wire storage cover which is drawn along the surface of the side plate 181 and then releasably engaged with the above-described product delivery device 200 together with the wiring of electrical components (solenoids and sold-out detection switches) of the product delivery device 200 It is comprised so that it may cover.

It is characterized by

  The invention according to claim 4 is characterized in that, in the vending machine according to claim 3, the cover portion of the wiring housing cover in which the internal temperature sensor is provided has a plurality of vent holes.

  The invention according to claim 5 is characterized in that, in the vending machine according to any one of claims 1 to 4, the in-compartment temperature sensor comprises a thermistor.

  According to the invention of claim 1 of the present invention, the product storage rack stored in the storage of the main body cabinet serving as the heat insulating housing, and at least the lower end outlet of the product storage passage of the product storage rack A commodity unloading device having electrical components of a drive unit for alternately moving the first stopper member and the second stopper member pivotably supported on the substrate to and from the commodity storage passage; A wiring storage cover having a storage space which is freely locked and which stores and protects the wiring of the electric component; and an in-chamber temperature sensor for detecting the temperature in the storage chamber in which the product storage rack is stored; A vending machine for adjusting the product stored in the product storage passage to a desired sales temperature based on the temperature detected by the in-chamber temperature sensor and providing the product for sale, By attaching to the rack, the wiring of the in-chamber temperature sensor is bundled together with the wiring of the electrical equipment of the product unloading device and stored in the wiring storage cover, and then one side of the left and right rack side plates (for example Since it can be led to the side plate and routed along the plate surface of the rack side plate, and the wiring routed along the rack side plate can be covered with the wiring storage cover detachably engaged with the commodity carry-out device, This has the effect of facilitating the operation of wiring the wiring of the temperature sensor and the wiring of the electrical components of the commodity carrying-out device.

  Further, according to the vending machine according to claim 2 of the present invention, in the vending machine according to claim 1, the internal storage temperature sensor is a wiring storage cover for storing the wiring of the electrical component of the commodity carry-out device By arranging the storage space in the storage space, it is possible to protect the in-chamber temperature sensor by the wiring storage cover.

  Further, according to the third aspect of the present invention, in the vending machine according to the first or second aspect, the wiring housing cover is along the mounting surface of the substrate of the commodity carry-out device and the mounting surface of the mounting surface is A base having an attachment portion engaged with the attachment portion, one end of which is continuous with one end of the base in the longitudinal direction, the other end is engageable / detachable with the other longitudinal end of the attachment, The interior temperature sensor is attached to the mounting part or protective cover part which is made of synthetic resin consisting of a cover part which forms a storage space together with the base by engaging with the other end in the longitudinal direction and closing it. By forming the holder to be held, the position of the in-chamber temperature sensor disposed in the accommodation space of the wire accommodation cover becomes constant, so the in-chamber temperature sensor disposed in the accommodation space of the wire accommodation cover And the position of It has the effect that it is possible to suppress the difference in detection accuracy caused by Rukoto.

  Further, according to the fourth aspect of the present invention, in the vending machine according to the third aspect, the cover portion of the wiring storage cover in which the internal temperature sensor is internally provided has a plurality of vent holes, Since the air in the storage space of the wiring storage cover can be communicated with the air outside the wiring storage cover through the vent holes, even if the storage temperature sensor is disposed in the storage space of the wiring storage cover There is no problem in the detection of the temperature inside the chamber by the temperature sensor. In addition, it is possible to approximate the thermal time constant (time change rate) of the in-compartment temperature sensor to the thermal time constant of the product by appropriately determining the number and the size of the vent holes. That is, since the in-chamber temperature sensor indirectly detects the product temperature and the temperature detection accuracy is high, the thermal time constant (time change rate) of the in-chamber temperature sensor is significantly different from the thermal time constant of the product When the internal temperature sensor is exposed to the interior as in the conventional device, when the commodity is adjusted to the desired sales temperature state (cold, hot, frozen state) after commodity loading, the interior temperature is the desired sales temperature Even when the state is reached (the internal temperature sensor outputs a detection signal), the product may not reach the desired sales temperature, and the product may not be sold that has not reached the desired sales temperature. For this reason, it is possible to cover the surface of the in-chamber temperature sensor exposed in the chamber with a heat insulating material to approximate the thermal time constant (time change rate) of the in-chamber temperature sensor to the thermal time constant of the product. It is difficult to coat the heat insulating material around the internal temperature sensor so that the time constant (time change rate) becomes constant. On the other hand, since the wire storage cover functions as a heat insulating material, the temperature of the storage space of the wire storage cover is delayed with respect to the temperature change outside the wire storage cover (inside), and this delay time is protected By appropriately selecting the number and size of the openings formed in the cover, the thermal time constant of the internal temperature sensor provided in the wiring storage cover can be approximated to the thermal time constant of the product. Have.

  Further, according to the invention as set forth in claim 5, in the vending machine according to any one of claims 1 to 4, the in-compartment temperature sensor comprises a thermistor so that the thermistor marketed as a general commodity can be stored. It can be adopted as an internal temperature sensor.

The pressing piece for controlling the carrier switch 74 is formed on a plate surface on the opposite side of the cam projection 731 and formed in a substantially V shape in a manner of projecting in a direction away from the plate surface, as shown in FIG. In this state, the contact of the carrier switch 74 is pressed. The output gear 73 is rotatably disposed by the base member of the unit case 70 and the bearing portion of the cover member.

  The carrier switch 74 is a so-called push button switch, and includes a contact (not shown). The carrier switch 74 is disposed in a region slightly above the output gear 73 and held by the base member of the unit case 70. The carrier switch 74 is turned on when the contact is pressed by the pressing piece of the output gear 73, and is turned off when the pressing piece of the output gear 73 is separated and the contact is not pressed. , And controls the motor 71 driven by the sale command so that the output gear 73 makes one rotation.

  The link levers 75 and 76 are resin molded products, and are rotatably supported by lever shafts 750 and 760 provided on a cover member of the unit case 70 passing through the base end portions 751 and 761. The tip portions 752 and 762 of the link levers 75 and 76 have hook shapes curved upward in a manner of projecting outward from an opening (not shown) formed by cutting out the base member and the cover member of the unit case 70 There is. Retaining pieces 753 and 763 provided on the base end portions 751 and 761 of the link levers 75 and 76 are elastically deformable plate-like elastic members extending rearward from the rear side of the base end portions 751 and 761. It is. The locking pieces 753 and 763 have the standby positions of the link levers 75 and 76 in the normal state in the position shown in FIG. 13A by the free ends thereof contacting the protruding pieces (not shown) provided on the cover member. I have decided.

  The wiring guide 8 is a resin molded product, and locks and fixes the sold-out detection switch 80 and guides the wiring W0 of the electric component (motor 71, sold-out detection switch 80). The wiring guide 8 is fitted between the right flange 1 d of the substrate 1 and the right wall 11 d of the opening 11 so as to be disposed on one side (right side) in the left-right direction of the substrate 1 (right side). The height of the wiring guide 8 is such that the height of the wiring guide 8 falls within the box of the substrate 1A of the secondary goods unloading device BM, and the wiring guide 8 guides the pair of goods unloading devices BM and BM in a back-to-back manner. Have a role as

  As shown in FIGS. 14 and 15, the wiring guide 8 includes a substantially F-shaped wiring storage portion 81, and a portion 811 corresponding to the upper horizontal line of the F character of the wiring storage portion 81 stores the wiring of the motor 7. A portion 812 corresponding to the lower horizontal line of the F shape accommodates the wiring of the sold out detection switch 80, and a portion corresponding to the vertical line of the F shaped portion along the right flange 1d of the substrate 1 corresponds to the motor 71 and the sold out detection switch 80. It is comprised so that wiring W0 may be accommodated. At the edge 8a of the wiring guide 8 along the right wall 11d of the opening 11, receiving spaces 82, 83 for receiving the shaft connecting portion 372 constituting the sold-out link 37 mounted on the right end of the first stopper member 3. And a switch fixing portion 84 accommodating the sold-out detection switch 80 at a position communicating with the receiving space 83.

  The sold-out detection switch 80 disposed in the switch fixing portion 84 is formed by integrating so-called two push-type switches, and two contacts urged to stand up by a “spring” (not shown). A child 801, 802 is provided. The sold-out detection switch 80 is disposed in the switch fixing portion 84 in such a manner that the contacts 801 and 802 are positioned in the front-rear direction (in FIG. 15, the contact 801 is on the back side and the contact 802 is on the front side). In this case, while the contactor 801 is positioned on the rotation locus of the sold-out pressing portion 374 of the sold-out link 37 interlocked with the first stopper member 3 shown in FIG. 15, the contactor 802 is the first stopper member 3A (this The first stopper member 3A is located on the rotation trajectory of the sold-out pressing portion 374 of the sold-out link 37A interlocked with the front side of the first stopper member 3 in FIG. In the sold-out detection switch 80 configured in this way, the contacts 801, 802 are positioned on the pivoting locus of the pressing portions 374, 374A of the sold-out links 37, 37A interlocked with the first stopper members 3, 3A. When the first stopper members 3 and 3A are opened to the commodity storage passage 183 at the maximum opening degree, the contactors 801 and 802 are pressed to detect sold-out.

  FIG. 16 is a side view showing the relationship between the opening degree of the sold-out detection switch 80 and the first stopper members 3 and 3A, as viewed from the right side. The first stopper members 3 and 3A are always urged toward the projecting position by the elastic biasing force of the torsion coil springs 300 and 300A, and are maximally opened when the first stopper members 3 and 3A project into the product storage passage 183 without holding the product. Degree. In FIG. 16, the upper limit position when the first stopper members 3 and 3A are opened to the maximum opening degree is indicated by an alternate long and short dash line. When the product falls on the first stopper members 3 and 3A opened at the maximum opening degree, the first stopper members 3 and 3A slightly rotate in the direction of retracting from the product storage passage 183 and then lower lower link pins 61 and 61A The rotation stopper 5 projects the product storage passage 183 and is locked at the standby position holding the product. The opening degree of the first stopper members 3 and 3A in this locked state is configured to be smaller by α than the maximum opening degree as shown in FIG. The sold out pressing portions 374, 374A of the sold out links 37, 37A which rotate in conjunction with the first stopper members 3, 3A in a state where the first stopper members 3, 3A hold the product and are locked at the standby position are sold out. It is configured to be separated (in a non-pressed state) from the contacts 801 and 802 of the detection switch 80, and the sold out detection switch 80 is turned off. When the product is sold out, the first stopper members 3, 3A open to the maximum opening after the product is sold. Thus, when the first stopper members 3, 3A are opened to the maximum opening degree after the product is sold, the sold-out links 37, 37A turn clockwise or counterclockwise in FIG. Press 801 and 802. As a result, the sold out detection switch 80 is turned on to output a sold out signal.

  In addition, since the first stopper members 3 and 3A are always urged toward the projecting position by the elastic biasing force of the torsion coil springs 300 and 300A and opened to the maximum opening degree, the first stopper members 3 and 3A When 3A opens to the maximum opening degree, it may bounce and the sold-out detection switch 80 may be repeatedly turned on and off. In addition, there is a time difference until the next sale item falls to the first stopper members 3 and 3A opened to the maximum opening degree after the sale item is discharged. Therefore, in the control unit that prevents chattering due to the bounding of the first stopper member 3 and processes the signal from the sold-out detection switch 80 in consideration of the time difference, the ON signal from the sold-out detection switch 80 continues for a predetermined time. A process of judging as "sold out" is performed.

  As shown in FIG. 1, the rising prevention member 101 is disposed on the front side of the substrate 1 in such a manner as to protrude and retract to the front side (the commodity storage passage 183) of the substrate 1. The rising prevention member 101 prevents the product from rising when the product initially loaded on the first stopper member 3 falls. That is, although the serpentine-type product storage rack is configured such that the loaded product in the overturned posture can drop without breaking the posture, the shape of the product container (in particular, a container with a narrow mouth, a barrel shape) Depending on the container, when it falls onto the first stopper member 3, the side-down posture may be disturbed to stand up. If the product stands up, the product may become clogged and become unmarketable, or the components of the product unloading device BM may be damaged due to the prevention of the protrusion of the second stopper member 4 into the product storage passage 183. It is The rising prevention member 101 is for suppressing such an unexpected situation as described above.

  As shown in FIG. 17, the rising preventing member 101 is bent in a mode in which the upper side formed as the bifurcated protruding portions 1011 and 1011 and the lower side having the contacting portions 1014 and 1014 are shifted in the left-right direction. Made of synthetic resin (for example, polyacetal). The bifurcated projections 1011 and 1011 are provided with engaging shafts 1012 and 1012 projecting outward, supporting shafts 1013 and 1013 projecting inwardly, and stopper pieces 1014 and 1014. The rising prevention member 101 is rotatably supported by engaging the engaging shafts 1012 and 1012 with the engaging holes of locking pieces 1 h and 1 h (see FIG. 6) formed by cutting and raising the substrate 1. . In this case, the engagement shafts 1012 and 1012 can be engaged with the engagement holes of the locking pieces 1h and 1h by bending the bifurcated projections 1011 and 1011 in a direction in which they approach each other. The torsion coil spring 1000 is attached to the support shafts 1013 and 1013 of the bifurcated projections 1011 and 1011. The torsion coil spring 1000 locks the one end 1000 a to the substrate 1 and the other end 1000 b to the base of the bifurcated projections 1011 and 1011, thereby advancing the rising prevention member 101 toward the commodity storage passage 183. Energize as you like. The advancing position of the rising prevention member 101 into the product storage passage 183 is restricted by the stopper pieces 1014 and 1014 coming into contact with the substrate 1.

  The rising prevention member 101 is movable between an advanced position where it is urged by the torsion coil spring 1000 to advance into the product storage passage 183 and a retracted position where it is pushed by the falling product and retracted from the product storage passage 183. . The rising prevention member 101 is located along the plane of the substrate 1 so that the main body 1010 is positioned between the guide projections 13 provided on the substrate 1 at the retracted position.

  The standup prevention member 101 allows passage of the goods by being pushed by the goods loaded first and moved to the retracted position, and the goods which have advanced and passed through the goods storage passage 183 at the same time the goods pass. Block retrogression of That is, when the product which has dropped to the first stopper member 3 tries to stand up, the product is prevented from standing up and corrected to a normal lying down posture. The rising prevention member 101 is pushed by the second and subsequent loaded products and moved to the retracted position.

  As shown in FIG. 1, the closing plate 102 is positioned above the second stopper member 4 and is suspended so as to cover the second stopper member 4 returned to the retracted position from the product storage passage 83 side. There is. The closing plate 102 is made of a strip-like steel plate elongated in the left-right direction, as shown in FIG. The length of the closing plate 102 in the left-right direction is substantially the same as the length of the holding portion 42 (see FIG. 11) of the second stopper member 4. Hooks 102 a and 102 a are provided at the upper end of the closing plate 102. By engaging the hooks 102a and 102a with the rectangular holes 1k and 1k (see FIGS. 5 and 6) formed in the substrate 1, the closing plate 102 is swingable around the hooks 102a and 102a. Similar to the conventional device, the closing plate 102 advances into the product storage passage 183 in conjunction with the movement of the second stopper member 4 to the projecting position, and the holding portion 42 of the second stopper member 4 and the next product to be sold. The gap between the holding portion 42 of the second stopper member 4 and the substrate 1 is closed by being interposed therebetween.

  The configuration of the secondary product delivery device BM differs from the configuration of the main product delivery device BM in that the motor drive unit 7 and the wiring guide 8 are not provided and the configuration of the sold-out link 37A interlocked with the first stopper member 3A. Except for this point, the configuration is the same as the configuration of the main product delivery device BM. When the secondary commodity unloading device BM is combined back to back with the primary commodity unloading device BM, the engagement piece 65 of the link member 60A of the secondary commodity unloading device BM is mounted on the primary commodity unloading device BM. The link lever 76 is covered from the upper side.

  The operation of the commodity carrying-out apparatus of the vending machine having such a configuration will be described based on FIGS. FIG. 19 is a side cross-sectional view of the commodity delivery apparatus before loading the commodity (also referred to as a replenishment standby state), FIG. It is operation | movement explanatory drawing at the time of goods carrying out of. In the following, the operation of the main product unloading device BM will be described with reference to FIG. 13 as appropriate.

  In the state before the commodity is loaded, the cam projection 731 of the output gear 73 of the motor drive unit 7 of the commodity delivery device BM is located at the uppermost position (see (a) in FIG. 13). Further, the pressing piece for the carrier switch 74 provided on the back 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 tip end portion 752 of the link lever 75 is at a position spaced downward from the engagement piece 65 of the link member 60. Therefore, the link member 60 is lowered by the biasing force of the return spring 66. By the upper link pin 61 and the lower link pin 62 supported by the lowered link member 60, as shown in FIGS. 19 and 20, the second stopper member 4 retracts from the commodity storage passage 183 and the first stopper member 3 Projects into the product storage passage 183. In this case, the second stopper member 4 is held at the retracted position by the upper link pin 61 supported by the lowered link member 60 entering the concave sliding groove 431 of the second stopper member 4.

  On the other hand, the first stopper member 3 is in the projecting position where the commodity storage passage 183 is opened to the maximum opening degree by the biasing force of the torsion coil spring 300. Along with the projecting operation of the first stopper member 3 into the product storage passage 183, the rotation stopper 5 also protrudes into the product storage passage 183 by the biasing force of the torsion coil spring (not shown). In this case, in the rotation stopper 5, the lock pin 51 is engaged with the small diameter groove portion 351 of the deformed groove 35 in the first stopper member 3 in a state where the first stopper member 3 is opened to the maximum opening degree. In this state, the rotation stopper 5 is directed to the retracted position by the lower link pin 61 supported by the link member 60 being lowered by the biasing force of the return spring 66 engaging with the lock groove portion 52 of the rotation stopper 5. Rotation is restricted. The engagement point between the lock pin 51 of the rotation stopper 5 and the small diameter groove portion 351 of the deformed groove 35 of the first stopper member 3 in the state where the retraction to the retraction position is restricted by the lower link pin 61 It is located closer to the retracted position than the dead point. As described above, in a state where the first stopper member 3 is opened to the maximum opening degree, the pressing portion 374 of the sold-out link 37 which rotates in conjunction with the first stopper member 3 presses the contact 801 of the sold-out detection switch 80. As a result, the sold out detection switch 80 is turned on.

  As described above, with the first stopper member 3 opened to the maximum opening degree, when the article G (see FIG. 20) is loaded, the article G loaded first is in the state opened to the maximum opening degree. 1 Drop onto the product holding portion of the stopper member 3. As the product G falls, the first stopper member 3 slightly pivots to the retracted position as follows, and is then locked in the standby state. That is, the lock pin 51 of the rotation stopper 5 is loosely fitted in the small diameter groove 351 of the deformed groove 35 of the first stopper member 3 with "play", and the first stopper member 3 is Rotate slightly toward the retracted position. In this case, the position of the lock pin 51 of the rotation stopper 5 is located closer to the retracted position than the dead center. The lower link pin 61 lowered in this state is engaged with the lock groove portion 52 of the rotation stopper 5 so that rotation of the rotation stopper 5 toward the retracted position is restricted. Act as a "stick". As a result, as shown in FIG. 20, the first stopper member 3 is locked in a state of holding the product G and protruding into the product storage passage 183 at an opening smaller than the maximum opening. The product G held by the first stopper member 3 is the product with the highest sales order (sale product G1). As described above, when the first stopper member 3 is locked in a state in which the first stopper member 3 protrudes to the product storage passage 183 at an opening smaller than the maximum opening, the pressing of the sold-out link 37 rotates in conjunction with the first stopper member 3 The part 373 is separated from the contact 801 of the sold-out detection switch 80, and the sold-out detection switch 80 is turned off. The goods G to be loaded next are stacked on the sale goods G1 held by the first stopper member 3 to become the next sale goods G2, and the goods G to be subsequently loaded are sequentially placed on the next sale goods G2 It piles up and it will be in a sales standby state (refer FIG. 20).

  Of a product selection button (a product selection button corresponding to a product stored in the product storage passage 183 in the first row from the front of the product storage passage 183 formed in line in the front-rear direction of the product storage rack 180 in FIG. When a sales command based on the operation is given, the motor 71 incorporated in the motor drive unit 7 is driven to rotate forward, and the output gear 73 rotates in the counterclockwise direction in FIG. 13 via the gear transmission mechanism 72. Do. When the output gear 73 rotates counterclockwise, the pressing piece provided on the back of the output gear 73 separates 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 normal direction until the output gear 73 rotates one time. When the cam protrusion 731 abuts on the base end 751 of the link lever 75 from the upper side due to the counterclockwise rotation of the output gear 73, the link lever 75 rotates in the clockwise direction in FIG. Due to the clockwise rotation of the link lever 75, the tip end portion 752 abuts on the engagement piece 65 of the link member 60. In this case, since the link member 60 is determined to have a larger rotational force than the biasing force of the return spring 67 in the clockwise direction of the link lever 75, the link lever 75 rotates in response to the clockwise rotation of the link lever 75. The member 60 ascends against the biasing force of the return spring 67. Then, while the cam projection 731 is in sliding contact with the proximal end portion 751 of the link lever 75, the link member 60 is held in the raised state.

  As the link member 60 ascends, the lower link pin 61 supported by the link member 60 also ascends, and the restriction of the rotation stopper 5 whose rotation to the retracted position is restricted by the lower link pin 61 is released. . The pivoting stopper 5 whose restriction has been released is pivoted toward the retracted position by the product load received through the first stopper member 3. The lock pin 51 of the rotation stopper 5 comes out of the small diameter groove portion 351 of the deformed groove 35 of the first stopper member 3 by the rotation of the rotation stopper 5 toward the retracted position, so that the lock of the first stopper member 3 It is released. As a result, the first stopper member 3 receives the load of the product, and starts pivoting from the protruding position which protrudes into the product storage passage 183 toward the retracted position. When the first stopper member 3 pivots to the retracted position where the first stopper member 3 retracts from the product storage passage 183, the commodity for sale G1 slips through the first stopper member 3 and is carried out downward (see FIG. 21). In this case, the rotation stopper 5 is also allowed to rotate toward the retracted position by the lock pin 51 sliding along the peripheral wall of the large diameter groove portion 352 of the deformed groove 35 of the first stopper member 3. When the sale product G1 slips through the first stopper member 3, the first stopper member 3 starts pivoting toward the projecting position by the biasing force of the torsion coil spring 300, and then stores the product in the state of being opened at the maximum opening degree It returns to the projecting position projecting into the passage 183. As the first stopper member 3 pivots to the projecting position, the pivoting stopper 5 also pivots to the projecting position that functions as a “support rod”.

  Further, as the link member 60 ascends, the upper link pin 62 which has entered the concave sliding groove 431 of the second stopper member 4 also ascends. In this case, the upper link pin 62 contacts the upper sliding wall 431 a of the sliding groove 431 and ascends while sliding on the upper sliding wall 431 a. As a result, the second stopper member 4 is pushed out from the retracted position to the projecting position projecting to the product storage passage 183. Then, when the upper link pin 62 ascends to the upper limit position facing the stopper surface 432 formed on the stopper wall 43 of the second stopper member 4, the second stopper member 4 retracts from the product storage passage 183 by the upper link pin 62. The pivoting toward the retracted position is restricted. Then, the second stopper member 4 moved to the protruding position protruding into the product storage passage 183 is held in contact with the lower part of the next sale product G2 moving downward by carrying out the sale product G1, and the next sale product Regulates G2 to move downward.

  As described above, the upward movement of the link member 60 releases the lock of the first stopper member 3 by the cooperation of the lower link pin 61 and the rotation stopper 5 and dispenses the commercial product G1 held by the first stopper member 3. On the other hand, in the operation of moving the second stopper member 4 from the retracted position to the projecting position to hold the next product G2, the cam projection 731 of the output gear 73 is in sliding contact with the base end 751 of the link lever 75 Is performed during

  Then, when the contact between the cam projection 731 and the base end 751 of the link lever 75 is released by the rotation of the output gear 73, the link member 60 is lowered by the biasing force of the return spring 67. As the link member 60 descends, the upper link pin 62 and the lower link pin 61 supported by the link member 60 also descend. When the upper link pin 62 in a state of being in contact with the stopper surface 432 of the second stopper member 4 descends, the second stopper member 4 is pressed by the next sale product G2 and moves toward the retracted position retracted from the product storage passage 183 . The descending upper link pin 62 abuts on the lower sliding wall 431 b of the concave sliding groove 431 of the second stopper member 4 and enters the sliding groove 431 while sliding on the lower sliding wall 431 b. When the next commodity G2 held by the second stopper member 4 falls onto the first stopper member 3 opened at the maximum opening degree by the movement of the second stopper member 4 to the retracted position, the first stopper member 3 Similar to the initially loaded product, the product is locked at the protruding position via the rotation stopper 5 in a state of being slightly moved toward the retracted position, and holds the next sale product G2 as a sale product. Thereafter, when the cam projection 731 returns to the standby state 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 sales standby state is restored.

    After the contact between the cam projection 731 and the base end 751 of the link lever 75 is released by the clockwise rotation of the output gear 73, the cam projection 731 of the output gear 73 returns to the standby position. In the middle, the cam projection 731 abuts on the base end 761 of the link lever 76, but the locking piece 763 made of an elastic member is elastically deformed to allow the link lever 76 to rotate clockwise. 731 returns to the return position without being blocked. When the cam projection 731 passes, the link lever 76 returns to the standby position shown in FIG. 13A by the action of the locking piece 763.

  The operation of the secondary product unloading device BM is stored in the product storage passage 183 in the second row from the front of the product storage passage 183 formed in the product storage rack 180 shown in FIG. When a sale command based on the operation of the product selection button corresponding to the selected product is given, the motor 71 incorporated in the motor drive unit 7 is reversely driven, and the output gear 73 is rotated as shown in FIG. In the clockwise direction. When the output gear 73 rotates clockwise, the pressing piece provided on the back of the output gear 73 is disconnected 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 reversely driven until it reaches (that is, a period until the output gear 73 makes one rotation). When the cam protrusion 731 abuts on the proximal end portion 761 of the link lever 76 from the upper side due to the clockwise rotation of the output gear 73, the link lever 76 rotates in the counterclockwise direction in FIG. When the tip end portion 762 of the link lever 75 abuts against the engagement piece 65A of the link member 60A due to the counterclockwise rotation of the link lever 75, the link member 60A ascends against the biasing force of the return spring 67A. Then, while the cam projection 731 is in sliding contact with the proximal end 761 of the link lever 76, the link member 60A is held in a raised state, and the contact between the cam projection 731 and the proximal end 761 of the link lever 76 is When the link member 60A is released, the link member 60A is lowered by the biasing force of the return spring 67A.

  As the link member 60A moves up and down, the lower link pin 61A and the upper link pin 62A supported by the link member 60A move up and down to move the first stopper member 3A and the second stopper member 4A to the product storage passage 183. The operation of holding the next sale product G2 as the sale product by the first stopper member 3A after taking out and selling the sale product G1 alternately is the same as the operation of the main product delivery device BM described above, and therefore, the overlapping description is Omit.

  Now, a wire housing cover 9 detachably attached to the lower part of the substrates 1, 1 of the pair of product delivery devices BM, BM is shown in FIGS. As shown in the figure, the wiring housing cover 9 has a front wall 93, a rear wall 94, and a base portion 91 in the form of a U-shaped cross section by a head 92 of an embodiment connecting the front wall 93 and the rear wall 94. The base portion 91 is made of synthetic resin including an L-shaped cover portion 96 continuously formed. The length in the left-right direction of the base 91 and the cover 92 is shorter than the length in the left-right direction of the substrate 1 in the commodity carry-out device BM, and the width in the front-back direction of the base 91 is the substrate 1, 1A It is set smaller than the width between flat faces of

  The head portion 92 of the base portion 91 is formed as a flat plate surface along the flange surface (attachment surface) of the lower flanges 1b and 1b (attachment portions) of the substrates 1, 1A of the goods delivery device BM, BM. The surface has notches 92a and 92a (see (b) in FIG. 22) on the left and right sides. These notches 92a and 92a are formed in the shape of a slit deeply cut in the longitudinal direction such that the left and right ends are open, and the open end side is cut along the front wall 93 and the rear wall 94. While being formed as a large groove, it is formed as a notched narrow groove in a mode in which the flat plate surface is divided in the front and back direction on the side closer to the center. Due to these notches 92a, 92a, the head 92 has a substantially X shape when viewed from a plane. An edge of the flat plate surface divided in the front and rear by the notches 92a and 92a, which faces the narrow grooves of the notches 92a and 92a, is a front side that protrudes upward in a manner opposed to sandwich the narrow groove. A mounting portion 92 b and a rear side mounting portion 92 c are formed. An engagement claw 92b1 (see FIG. 23A) facing forward is provided on the front attachment portion 92b, and an engagement claw 92c1 facing backward on the rear attachment portion 92c (see FIG. a) see). The front side attachment portion 92b having the engagement claws 92b1 and the rear side attachment portion 92c having the engagement claws 92c1 form a hook as a whole.
