[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention includes a pusher that moves with respect to a mounting table on which products are stacked, and moves the pusher to the front end side of the mounting table while pressing the pusher against the lowest product, thereby carrying out the lowest product. The present invention relates to a carry-out device, and particularly to a product carry-out device suitable for a vending machine that sells box-shaped products such as cigarettes.
[0002]
[Prior art]
As a conventional product unloading device, for example, a device shown in FIG. 31 is known. This product unloading device is the lowest one of the box-shaped products 1002 stacked on the mounting table 1001 by a retractable pusher 1000 that is reciprocated by a built-in napier screw mechanism (not shown). In this configuration, products are sequentially pushed out from the front opening (left side in FIG. 31) 1003 and carried out. The opening 1003 communicates with a product carrying passage (not shown). In this product unloading device, in order to increase the number of products 1002 stored in the mounting table 1001, the products 1002 are formed so as to be long in the depth direction such that the products 1002 are stacked in two front and rear rows. The next sale product 1002 falls with the removal of the lowest order product 1002, becomes the next lowest order product 1002, and is unloaded by the same unloading operation as described above (for example, see Patent Document 1).
[0003]
FIG. 32 shows another example of a conventional product unloading device. In this product unloading device, among the box-shaped products 2003 stacked on the mounting table 2002, the lowest order products 2003 are sequentially moved forward (to the left in FIG. 32) by a pusher 2001 provided on a rotating endless unloading belt 2000. And is carried out by being pushed out from the opening portion 2004. The carry-out belt 2000 is made to go around by the driving unit 2005. The posture control member 2006 that periodically interlocks with the rotation of the carry-out belt 2000 and appears and disappears on the lower surface behind the lowest product 2003 to be extruded moves the rear end of the next sales product 2003 that falls as the lowest product 2003 moves. By lifting, the attitude of the next sale product 2003 is regulated to be substantially horizontal (for example, see Patent Document 2).

[Problems to be solved by the invention]
By the way, in this type of product unloading device, there are cases where products having different heights are unloaded. However, the amount of protrusion of the pushers 1000 and 2001 from the mounting tables 1001 and 2002 against the product is limited to the height of the product having the smallest height (hereinafter, simply referred to as the thinnest product). In other words, in the above-described commodity discharging apparatus, unless the protrusion amounts of the pushers 1000 and 2001 are set to be smaller than the smallest height of the products to be discharged, the products cannot be discharged one by one.
[0006]
For this reason, for example, when a product having a height higher than the thinnest product is carried out, the pressing point by the pushers 1000 and 2001 may be located below 1/2 of the height of the lowest product. When the product is carried out in such a state, the front end of the lowest product is flipped up, and there is a possibility that the product may be jammed due to disorder in the carry-out posture. In particular, immediately before the lowest order product is carried out, the load of the next sales item located above is applied to the upper edge of the rear end portion, so that the above-described problem becomes more remarkable.
[0007]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a product unloading device capable of adjusting a product unloading posture and stably unloading a product.

BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0016]
(Embodiment 1)
FIG. 1 schematically shows a product unloading device according to a first embodiment of the present invention, and FIG. 7 shows a part of a vending machine incorporating the product unloading device in a standby state for sale. I have. As can be seen from these figures, the housing of the commodity carrying-out device generally indicated by the reference numeral 3 is formed in an L-shape or a horizontal T-shape as a whole by engaging or fitting the left and right cases 4 and 5. ing. Each of the cases 4 and 5 has a vertical portion 4a, 5a which is fitted into a concave portion 1d formed at a lower end portion of the wall surface of the commodity storage column 1 of the vending machine and extends substantially vertically, and substantially extends from the vertical portion 4a, 5a. And mounting tables 4b and 5b which provide a table on which the product 2 is mounted, which extends horizontally horizontally. It is preferable that each of the cases 4 and 5 is integrally formed of an appropriate resin (for example, an ABS resin). In the first embodiment, the mounting tables 4b and 5b support the product 2, but it is obvious that the product 2 is not necessarily required.
[0017]
As shown in FIG. 7, locking claws 5c and 5d are formed on the upper and lower end surfaces of the vertical portion 5a (not shown in FIG. 1), and these locking claws 5c and 5d are recessed. The entire housing is assembled to the product storage column 1 by engaging the corresponding engagement holes 1e and 1f formed in the upper and lower wall surfaces defining 1d. The engaging claw 5d is elastically deformed so as to protrude from the lower wall surface so as to be easily attached to and detached from the recess 1d, and the amount of protrusion is adjusted from the side of the product storage passage 1a. It is formed to be possible.
[0018]
An opening 11 is formed in each of the cases 4 and 5 near a connection point between the vertical portion and the mounting table portion, and when the pusher 10 described later advances from the sales standby position to the product unloading position, a reciprocation described later. A part of the moving body 8 is exposed from the opening 11 (see FIGS. 8 to 11), receives the rear end of the falling next sale product 2b, and prevents the next sale product 2b from inverting. , The posture can be controlled.
[0019]
As shown in FIGS. 2 to 6, the cases 4 and 5 are used to release a part of the reciprocating moving body 8 so as not to receive the interference of the vertical portion when the reciprocating moving body 8 described later moves. Notches 19 and 20 are formed. Thereby, the depth dimension of the cases 4 and 5, which is the longitudinal direction of the mounting table portions 4b and 5b, is reduced. Although not denoted by a reference numeral, a notch is also provided to escape a part of the motor 6 (FIG. 1) constituting the drive unit of the reciprocating moving body 8 for the same purpose.
[0020]
When the product 2 is sold out, the sold-out detection lever 16 protruding from the mounting table portion 5b is released from contact with the product 2 and protrudes toward the product storage passage 1a, and detects the sold-out of the product 2 by the switch 17. Is what you do. The switch 17, a switch 15, a motor 6, a gear train 7 (which constitutes a drive unit of the reciprocating body 8 together with the motor 6), etc., are mounted on a board 9, and the board 9 is mounted on a vertical portion 5 a of the case 5. It is fixed by appropriate means inside. Although not shown, the right end of the sold-out detection lever 16 extends rightward in FIG. 1 in the mounting table 5b and enters the operation area of the switch 17. The sold-out detection lever 16 swings each time the pusher 10 moves, whereby the switch 17, which is a microswitch, also operates ON / OFF. However, in the first embodiment, the electric circuit (not shown) is designed to ignore the change in the state of the switch 17 during the operation of the motor 6 that drives the reciprocating moving body 8, so that the motor 6 does not operate. Only when the state of the switch 17 changes during the period, it can be determined that “out of stock”.
[0021]
Next, as shown in FIGS. 1 to 6, the reciprocating moving body 8 formed in an arc shape moves a pusher 10 for pushing out a product, which is connected to a tip end thereof, on the mounting bases 4b and 5b. In addition, the guide portions (guide portions) 18 and the rails 18a for the moving body, which are similarly formed in arc shapes on the inner surfaces of the vertical portions 4a and 5a of the cases 4 and 5 and the mounting tables 4b and 5b, are guided. Designed to move. The movable body guide groove 18 and the movable body rail 18a in the mounting table portions 4b and 5b are curved upward from substantially the center to the front end of the mounting table portion, and allow the pusher 10 to move upward. I have. A toothed portion 8a (particularly, see FIG. 5) is formed on the outer peripheral portion (radially outer peripheral surface) of the reciprocating moving body 8, and the toothed portion 8a reduces the driving force of the motor 6 and transmits the driving force. And the output gear 7a of the gear train 7 which is engaged.
[0022]
As can be seen from FIGS. 2 to 6, pins (guide protrusions) 8 b for engaging with the pusher 10 are provided from the left and right side surfaces near the distal end of the reciprocating moving body 8. The pusher 10 includes a block-shaped push plate 10A that can come into contact with a product for sale, and left and right arm portions 10B that support the push plate 10A at an upper end and have a protrusion 10b at a lower end. The pin 8b provided on the reciprocating moving body 8 is inserted into a curved elongated hole (guide recess) 10a provided on the arm portion 10B of the pusher 10, and reciprocates so that the pusher 10 makes a desired movement. It is designed to be slidable in the elongated hole 10a as the moving body 8 moves.
[0023]
Further, a protrusion 8c is formed on the side surface of the reciprocating moving body 8 so as to engage with the moving body guide groove 18 and slide in the moving body guide groove 18. In the preferred embodiment 1 of the present invention, the reciprocating body 8 and the pusher 10 are integrally formed of a resin (for example, polyacetal resin).
[0024]
As shown in FIGS. 1 to 6, the pusher 10 interlocking with the reciprocating body 8 is guided by a pusher guide groove (guide portion) 12 formed on the inner surface of the case 4, 5. Thus, it moves on the mounting table portions 4b and 5b. As for the size and shape of the pusher guide groove 12 and the elongated hole 10a, the protruding height from the mounting table gradually increases as the pusher 10 advances from substantially the center of the mounting table 4b, 5b toward the front end. In this way, the pusher 10 is set so that most of the pusher 10 projects forward from the front ends of the mounting tables 4b and 5b when approaching the final stage of carrying out the product (see FIGS. 8 to 11). As illustrated in FIG. 10, when the lowest product 2a is paid out to the product discharge passage 1b, the next product 2b is lifted up or supported by the pusher 10 to be below the front end face of the same product 2b. The height of the rim is higher than the sales product having the constant height H by the height h, and the space S of the opening 1c in front of the pusher 10 is expanded, so that the lowest-order product 2a is reliably paid out, This is for stabilizing the posture of the next sale product 2b when it falls. Further, even when the height of the lowest product 2a to be carried out is larger than the thinnest product, the pressing point by the pusher 10 is positioned above 1/2 of the height of the lowest product 2a. Things.
[0025]
Further, the pusher 10 is provided with a pin 10c on the protrusion 10b on the arm 10B. As shown particularly well in FIGS. 5 and 6, the pin 10 c has a protrusion 14 a formed at the front and rear ends of a box-shaped slide piece 14 movably mounted in the mounting table 5 b, and a pusher 10. It is designed to engage at both ends of the operation stroke. That is, the slide piece 14 having the inclined step portion 14b operates when the pusher 10 comes to the front end position and the rear end position, and turns on / off a switch 15 (for example, a micro switch) that contacts the inclined step portion 14b. Thus, the position of the pusher 10 is detected.
[0026]
Then, by using the position detection information, the rotation direction of the motor 6 is controlled to be either forward or reverse, so that the operation direction of the pusher 10 can be controlled. In the illustrated example, when the pusher 10 comes to the front ends of the mounting table portions 4b and 5b (commodity payout position in FIG. 6), the arm of the switch 15 gets over the inclined step portion 14b and turns ON, and the pusher 10 is mounted. The arm of the switch 15 is designed to return to the OFF position when it comes to the rear end of the mounting tables 4b, 5b (sales standby position in FIG. 5).
[0027]
Next, a standby support member 13 of a resin molded product is swingably provided on the front side of the mounting table portions 4b and 5b. Although not shown or described in detail, the standby support member 13 has its rear end pivotally supported by a relatively front portion of the mounting table 4b, and swings up and down in accordance with the position of the pusher 10. It is provided to control the attitude of the lowest order product 2a to hold the product 2a or to promote payout. That is, as shown in FIG. 7, in the sales standby state, the standby support member 13 abuts on the front end of the lower surface of the lowest order product 2a, and the mounting table portions 4b, 5b are held so as to keep the attitude of the product horizontal. Holding in cooperation.
[0028]
Therefore, as in the conventional case, when the number of stacked products is reduced and the product load applied to the lowest product from above is small, if the vending machine is shaken by mischief or the like, the posture of the lowest product becomes unstable. As a result, the product may drop from the opening, or the product may be disturbed, causing the product to be jammed at the time of sale. Since the product abuts against the front end of the lower surface of the product 2a and keeps the posture of the product horizontally, the lowest product 2a can be stably and reliably held regardless of the number of stored products 2.
[0029]
Further, as can be understood from FIGS. 8 and 9, when the pusher 10 moves forward and pushes the lowest order product 2a at the time of pushing out the product, the standby support member 13 slightly lowers, and further pushes out the lowest order product 2a. , As shown in FIG. Then, when the pusher 10 returns to the sales standby position again, it finally returns to a substantially horizontal state.
[0030]
As described above, the standby supporting member 13 assists the drop operation by retreating to a position where it does not interfere with the lowest product 2a to be carried out and dropped in a series of product dispensing processes, and at the same time, pushes the pusher when shifting to the sales standby state. When the user attempts to retreat (when shifting from the state shown in FIG. 11 to the state shown in FIG. 7), the standby support member 13 is rotated upward to be substantially horizontal, and the falling next sales product 2b is securely taken. It is designed to hold.
[0031]
In order to assist the above-mentioned product dropping operation, the length of the substantially horizontal standby support member 13 protruding from the mounting tables 4b and 5b is half the horizontal length (length in the depth direction) of the product 2. It is set slightly shorter than. This is so that a fulcrum (front end of the standby support member 13) when the product 2 is pushed forward by the pusher 10 and falls down is formed slightly forward, and the posture is quickly broken down and rotated so that the product 2 can be dropped quickly. It is intended to be.
[0032]
As shown in FIG. 10 and as described above, at the moment when the lowest order product 2a falls into the product exit passage 1b, the pusher 10 supports the next sale item 2b and lifts the front end thereof. The space S below the front end of the next sale product 2b can be expanded. When the lowest product 2a falls, the standby support member 13 has already been rotated to a position where it does not hinder the fall, so that the product 2a rotates counterclockwise in FIG. 10 and falls. At this time, since the above-mentioned expanded space S is a space for allowing the product 2a to be easily rotated, the rear end of the product 2a does not catch on the front end of the next sales product 2b, and the product is smooth. Unloading can be performed.
[0033]
A main drive mechanism (motor 6, gear train 7, toothed portion 8a of the reciprocating body 8) for operating the pusher 10 is provided in the vertical portions 4a, 5a of the cases 4, 5, and the substrate 9 is also vertically mounted. Since the space is provided in the sections 4a and 5a, the space can be effectively used, and the depth dimension of the vending machine can be reduced. In particular, the provision of the reciprocating moving body 8 operating in an arc shape inside the vertical portions 4a and 5a of the cases 4 and 5 and the mounting table portions 4b and 5b enables a large operation stroke to be secured in a narrow space. This contributes to miniaturization.
[0034]
In addition, since the toothed portion 8a that meshes with the gear train 7 that transmits the driving force of the motor 6 is formed on the outer peripheral portion of the belt-shaped reciprocating moving body 8, the reciprocating moving body 8 can be reliably operated. By combining various gears, a predetermined driving force can be ensured even in a narrow space.
[0035]
Further, since there is no need to provide the main driving mechanism in the mounting tables 4b and 5b of the cases 4 and 5, the mounting tables 4b and 5b can be made thinner and the number of stored products can be increased. For example, when the product unloading device 3 according to the first embodiment is arranged in the product storage column under substantially the same conditions as in the related art, it has been confirmed that the number of products can be increased by about 100 in the entire vending machine.
[0036]
Further, as described above, by the cooperation of the pusher 10 and the standby support member 13, the posture of the product 2 can be controlled stably, and the product 2 can be reliably held and carried out.
[0037]
As described above, according to the product unloading device of the first embodiment, as the pusher 10 advances from substantially the center of the mounting tables 4b and 5b toward the front end, the protruding height from the mounting table gradually increases. Since the height is set to be higher, the thinnest products can be carried out one by one, and at the time of carrying out a product having a height higher than the thinnest product, the pressing point by the pusher 10 is set to 1 / H of the height of the lowest product. 2 can be positioned above. Therefore, there is no possibility that the front end of the lowest order product is flipped up, and there is no problem such as product jam due to disturbance in the carry-out posture.
[0038]
(Embodiment 2)
FIG. 12 shows a product unloading device according to Embodiment 2 of the present invention, and FIGS. 19 to 29 show examples of application. The product discharge device exemplified here is applied to a vending machine that sells box-shaped products such as cigarettes, and is disposed at the lower end of a product storage column 30 that stores products, as in the first embodiment. And a housing 40 molded of a synthetic resin such as an ABS (acrylonitrile-butadiene-styrene) resin.
[0039]
The housing 40 is configured by joining a pair of left and right cases 40L and 40R to each other. The housing 40 is provided with a vertical portion 41 and a mounting table portion 42. The vertical portion 41 is a portion that is fitted to the rear wall 31 that constitutes the product storage column 30 of the vending machine, and extends along the vertical direction. The mounting table portion 42 is a portion that constitutes a mounting table on which products are stacked, and extends substantially horizontally forward from a substantially middle portion of the vertical portion 41. The length of the mounting table 42 in the front-rear direction from the vertical portion 41 is shorter than the length of the product to be carried out in the front-rear direction. The upper surface of the mounting table portion 42 enables the transport of the thickest product, that is, the largest product among the products to be sold, with respect to the upper edge of the carry-out port 33 provided on the front wall 32 constituting the product storage column 30. And the height at which only the thinnest product, that is, the smallest product among the products to be sold, can be carried out. A reciprocating groove 43 for projecting a pusher 50, described later, is formed in the entire area along the front-rear direction at the center of the upper surface of the mounting table 42, and a sold-out detection, described later, is formed on the upper surface of the left case 40L. A detection groove 44 for allowing the lever 60 to protrude and retract is formed along the front-rear direction. A storage recess 45 for accommodating a push plate 51 of a pusher 50 to be described later is provided at a meeting portion of the front surface of the vertical portion 41 with the upper surface of the mounting table portion 42.
[0040]
Further, the housing 40 described above is provided with a reciprocating movement mechanism 70 and a pusher 50 in the right case 40R as shown in FIG. 13, while a sold-out detection lever 60 is provided in the left case 40L as shown in FIG. A drive source 80, a guide groove 90, a standby support member 100, an unloading support member 110, a standby support driver 120, and an unloading support driver 130 are provided.
[0041]
The reciprocating mechanism 70 is a so-called Napier screw mechanism, and includes a shaft member 71 and a reciprocating body 72 as shown in FIGS. 13 and 16 to 18.
[0042]
The shaft member 71 is a columnar member having a series of reciprocating spiral grooves 711 on the peripheral surface. The shaft member 71 is disposed substantially horizontally in the front-rear direction inside the mounting table portion 42, and can rotate about the axis. A driven gear 712 is integrally formed at the base end of the shaft member 71. The driven gear 712 meshes with the gear train 73 housed in the right case 40R.
[0043]
The reciprocating moving body 72 has a block shape, and has a guide hole 721 at a portion extending from the front end surface to the rear end surface. The reciprocating body 72 is movable along the axial direction of the shaft member 71 by fitting the shaft member 71 into the guide hole 721, while the lower part of the mounting table 42 of the right case 40R is formed. The moving contact portion 722 provided on the lower end surface is arranged close to the wall, and regulates rotation about the axis with respect to the shaft member 71.
[0044]
The reciprocating body 72 has a guide projection 723 integrally provided on the left side surface thereof, and an accommodation hole 724 provided at a portion extending from the upper end surface to the lower end surface thereof.
[0045]
The guide projection 723 has a columnar shape, and projects substantially horizontally from the upper front corner of the reciprocating movable body 72 to the left.
[0046]
The accommodation hole 724 is formed so that its axis is orthogonal to the axis of the guide hole 721, and has a pair of elastic claw pieces 725 on the peripheral surface at the upper end. The pair of elastic claw pieces 725 are formed integrally with the reciprocating moving body 72, and have claw portions 725a at respective upper ends. The claw portions 725a protrude inward at a substantially right angle and then gradually incline outwardly upward. When the elastic claw pieces 725 are in a normal state, the claw portions 725a It is formed so as to protrude inward from the peripheral surface, but to be located outside the inner peripheral surface of the accommodation hole 724 when the elastic tongue is elastically deformed outward.
[0047]
The rotating piece 74 is accommodated in the accommodation hole 724. The rotating piece 74 includes a cylindrical large-diameter portion 741 rotatably fitted into the accommodation hole 724 of the reciprocating moving body 72, a small-diameter portion 742 provided at an upper end of the large-diameter portion 741, and a large-diameter portion. 741 and a driven piece 743 provided at the lower end thereof are integrally formed. The driven piece 743 is narrower in width than the reciprocating spiral groove 711 of the shaft member 71 and has a lower end edge formed in an arc shape, and rotates the shaft member 71 around the axis while being positioned in the reciprocating spiral groove 711. In this case, it is possible to move along the reciprocating spiral groove 711. When the rotating piece 74 is inserted into the housing hole 724 with the driven piece 743 directed downward, the elastic claw 725 elastically expands and deforms due to the large diameter portion 741 slidingly contacting the claw 725a. The driven piece 743 can be positioned in the reciprocating spiral groove 711 of the shaft member 71, and the driven piece 743 can be appropriately tilted with respect to the shaft member 71 by rotating around the own axis. When the driven piece 743 is located in the reciprocating spiral groove 711 of the shaft member 71, the claw 725a of the elastic claw 725 is located at the small-diameter portion 742, and the elastic claw 725 returns to move. By engaging with the step between the small-diameter portion 741 and the small-diameter portion 742, the drop of the rotating piece 74 from the accommodation hole 724 is prevented. In other words, in the reciprocating mechanism of the second embodiment, as long as the rotating piece 74 integrally formed with the driven piece 743 is inserted into the receiving hole 724 of the reciprocating moving body 72, the reciprocating piece 743 does not drop out. This allows the movable body 72 to hold the movable body 72, thereby significantly improving the assembly workability as compared with the conventional one.
[0048]
The pusher 50 protrudes from the upper surface of the mounting table portion 42 through the reciprocating groove 43 and pushes out the product. As shown in FIG. 16, the pusher 50 has a plate-shaped main plate 52 and a push plate 51 and a ridge 53. It is configured.

[0060]
The shaft member 71, the reciprocating body 72, the gear train 73, the rotating piece 74, the pusher 50, the sold-out detection lever 60, the drive gear 81, the standby support member 100, the carry-out support member 110, the standby support drive body 120, Each of the carry-out support driving members 130 is formed of a synthetic resin such as polyacetal.
[0061]
FIG. 19 to FIG. 29 show the operation of the vending machine to which the above-described product unloading device is applied, particularly when the thinnest product 200 is sold. Hereinafter, the product discharging device according to the second embodiment will be described in detail with reference to these drawings as appropriate.
[0062]
First, in the commodity discharging device, as shown in FIG. 19, the reciprocating moving member 72 is located at the rearmost end of the mounting table portion 42, and the rear receiving surface of the discharging support driver 130 is attached to the rear end surface of the moving contact portion 722. The state in which the protrusion 136 is in contact is a commodity sales standby state.
[0063]
In the merchandise sales standby state, the standby support driver 120 and the unloading support driver 130 are located at the rearmost end of the mounting table 42, respectively. Accordingly, the detection protrusion 133 is located rearward of the stroke detection sensor 140, and the stroke detection sensor 140 is turned off. Further, as shown in FIG. 20, the standby regulating portion 122 of the standby support driving member 120 is located on the upper surface of the standby operating portion 103 of the standby support member 100, and the standby support member 100 swings to the uppermost position. The portion 102 is located on an extension of the upper surface of the mounting table portion 42, and the unloading restricting portion 132 of the unloading support driver 130 is located on the upper surface of the unloading action portion 113 of the unloading support member 110, and the unloading support member 110 is By swinging to the uppermost position, the carry-out support portion 112 is positioned on an extension of the upper surface of the mounting table portion 42. As a result, the lower surface of the front end of the product 200 projecting from the front end of the mounting table 42 is supported by the standby support member 100 and the unloading support member 110, and the stopper 104 of the standby support member 100 is attached to the front end surface of the product 200. Therefore, even if a malicious object shakes the vending machine in the front-rear direction, the stacking posture of the products 200 stacked on the upper surface of the mounting table 42 is disturbed regardless of the number of the remaining products 200. And there is no risk of falling into the carry-out port 33.
[0064]
When a sales command is given from the above-described commodity sale standby state, a control unit (not shown) of the commodity unloading device drives the drive source 80 to drive the reciprocating mechanism via the drive gear 81, the gear train 73, and the driven gear 712. The shaft member 71 is rotated in one direction. When the shaft member 71 rotates, the driven piece 743 moves forward along the reciprocating spiral groove 711, so that the reciprocating moving body 72 starts linearly moving toward the front end of the mounting table portion.
[0065]
Here, even when the rotating piece 74 rotates according to the tilting of the driven piece 743, the claw portions 725a of the pair of elastic claw pieces 725 are engaged with the rotating piece 74, so that the rotating piece 74 reciprocates. It does not fall out of the accommodation hole 724 of the body 72.
[0066]
The movement of the reciprocating body 72 is transmitted to the pusher 50 via the guide protrusion 723, and the pusher 50 starts to move to the front end side along the guide groove 90 after all.
[0067]
When the pusher 50 starts to move to the front end side, the front end of the main plate 52 of the pusher 50 comes into contact with the first contact piece 123 of the standby support driver 120 as shown in FIG. The standby support driver 120 is moved to the front end side of the mounting table 42 via the piece 123. As a result, as shown in FIG. 22, the standby regulating portion 122 of the standby support driver 120 is located on the front end side of the standby bearing portion 101, and the downward swing of the standby support member 100 is allowed. Therefore, the standby support member 100 is held in a state of swinging downward by its own weight, and the movement of the lowermost commodity 200 to the front end side with respect to the mounting table 42 is allowed. However, as for the unloading support member 110, the unloading support driving body 130 is continuously located on the rear end side of the mounting table 42, and thus remains in a state of being positioned on the upper surface extension of the mounting table 42.
[0068]
When the shaft member 71 further rotates from the above-described state, the reciprocating moving body 72 moves to the front end side, so that the pusher 50 also moves to the front end side. In this case, when the main plate 52 of the pusher 50 contacts the first contact piece 123 and further the second contact piece 124 after the standby support driver 120 moves to the front end side of the mounting table section 42, Since the first contacting piece 123 and the second contacting piece 124 are elastically deformed and evacuated from the movement area of the main plate 52 in the pusher 50, the pusher can be moved without changing the position of the standby support driver 120. The movement of 50 toward the front end side is sequentially allowed. Needless to say, the first contact piece 123 and the second contact piece 124 resiliently return after the pusher 50 has passed, and again project into the movement area of the main plate 52 in the pusher 50. .
[0069]
When the pusher 50 moves to the front end side, the push plate 51 of the pusher 50 eventually comes into contact with the rear end face of the lowest order product 200, and pushes the lowest order product 200 toward the mounting table 42 toward the front end side. In this case, as described above, while the protrusion 53 of the pusher 50 is located at the rear end side of the guide groove 90, the amount of the protrusion of the pusher 50 from the upper surface of the mounting table 42 is minimized. Since the height of the thin product 200 is smaller than the height of the thin product 200, the push plate 51 of the pusher 50 does not come into contact with the rear end face of the next sales product 200, and only the lowest product 200 is pushed to the front end side.
[0070]
Here, during the operation described above, if the projecting length of the lowest order product 200 from the front end of the mounting table portion 42 exceeds 全長 of the total length, the lowest order product 200 normally assumes the forward inclined posture. In some cases, the push plate 51 of the pusher 50 may come off the rear end face. In the case of the thinnest product 200, the next sale product 200 together with the lowest order product 200 is inclined forward on the upper surface of the mounting table 42, and there is a possibility that the two products 200 may fall from the carry-out port 33 as they are.
[0071]
However, according to the product unloading device of the second embodiment, as shown in FIG. 23, as the pusher 50 moves toward the front end, the pusher 50 eventually moves upward with respect to the upper surface of the mounting table 42. Then, the lowermost product 200 is pushed out at a position higher than the rear end face thereof, so that the lowermost product 200 is carried out stably. In addition, even when the pusher 50 moves forward to the front end side, the lower surface of the front end of the lowest order product 200 is continuously supported by the carry-out support member 110, and as shown in FIG. Is moved to the front end side only, the lowest order product 200 assumes the forward tilting posture, while the next selling product 200 assumes the rearward tilting posture. Therefore, in order to shorten the depth dimension, even in a product discharging apparatus in which the length of the mounting table portion 42 in the front-rear direction is shorter than the length of the product to be discharged in the front-rear direction, the push plate 51 of the pusher 50 is initially pressed. In this state, it is possible to prevent a situation in which the product 200 comes off the rear end face, and there is no possibility that a situation in which two products 200 are carried out at the same time.
[0072]
Further, in the case of carrying out the thinnest product 200, according to the product carrying-out device of the second embodiment, the pusher 50 replaces the lowest product 200 on the lower surface of the next product 200 while moving to the front end side. Since the contact is made, the load applied to the lowest order product 200 can be reduced. Therefore, not only can the front end of the lowermost product 200 be prevented from jumping upward, but also the lowermost product 200 can easily take a forward tilted posture, stabilizing the carry-out posture and possibly causing a product jam. Absent.
[0073]
As shown in FIG. 24, in a state where the pusher 50 has moved until the lowermost product 200 is in the forwardly inclined posture, the front end face of the moving contact portion 722 provided on the reciprocating moving body 72 is in front of the unloading support driving body 130. When the pusher 50 moves, the unloading support driving body 130 moves to the front end side in contact with the pressure receiving projection 135. As a result, as shown in FIG. 26, the unloading restricting portion 132 of the unloading support driving member 130 is located on the front end side of the unloading bearing portion 111, and the unloading support member 110 is allowed to swing downward. Therefore, the carrying-out support member 110 is held in a state of swinging downward by its own weight. That is, as shown in FIG. 25, when the lowest product 200 is carried out through the exit 33, both the standby support member 100 and the carry-out support member 110 swing downward, and the carry-out area of the lowest product 200 Therefore, there is no possibility that the standby support member 100 and the unloading support member 110 will prevent the lowermost product 200 from being unloaded.
[0074]
In addition, the reciprocating body 72 and the pusher 50 are linked via a slot 54 inclined upward to the front end of the mounting table 42. Therefore, as shown in FIG. 25, when the reciprocating movable body 72 reaches the front end of the shaft member 71 inside the mounting table 42, the pusher 50 may be moved to protrude from the front end of the mounting table 42. It becomes possible to carry out the lowest order product 200 more reliably.
[0075]
In addition, as shown in FIG. 25, the pusher 50 abutting on the lower surface of the next sale product 200 has the lowest order product between the upper surface of the mounting table portion 42 and the lower edge of the front end surface of the next sale product 200 inclined backward. A gap larger than the height of 200 will be secured. Therefore, when the lowest product 200 is carried out of the mounting table portion 42 in the forward tilted posture, the next sales product 200 does not affect the lowest product 200, so that it is possible to carry out the product stably. It becomes possible.
[0076]
As shown in FIG. 25, when the unloading support driver 130 moves to the front end side of the mounting table 42, the detection protrusion 133 presses the detector of the stroke detection sensor 140 and turns on the stroke detection sensor 140. The control unit (not shown) to which the ON signal is given from the stroke detection sensor 140 temporarily stops the rotation of the shaft member 71 by the driving source 80, that is, temporarily stops the pusher 50 at the front end of the mounting base 42, By driving the drive source 80 again, the shaft member 71 is rotated in the same direction and the movement of the reciprocating body 72 is restarted. At this time, the reciprocating moving body 72 that has reached the front end of the shaft member 71 moves toward the rear end of the mounting table 42 by the driven piece 743 reciprocating the shaft member 71 along the reciprocating spiral groove 711. The linear movement is started, and eventually the pusher 50 is moved to the rear end side along the guide groove 90.
[0077]
When the pusher 50 starts moving to the rear end side, as shown in FIG. 27, the front end of the main plate 52 of the pusher 50 comes into contact with the second contact piece 124 of the standby support driver 120, and the second contact The standby support driver 120 is moved to the rear end side of the mounting table 42 via the contact piece 124. As a result, as shown in FIG. 28, the standby regulating portion 122 of the standby support driving body 120 moves to the rear end side beyond the standby bearing portion 101, and moves the standby support member 100 to the uppermost position via the standby operating portion 103. By swinging, the standby support portion 102 is positioned on the upper surface extension of the mounting table portion 42 again. At this time, when the standby support member 100 swings upward, the standby support member 100 abuts on the lower surface of the unloading support member 110, thereby also swinging the unloading support member 110 to the uppermost position. It is positioned on the extension of the upper surface of the mounting table 42. As a result, as shown in FIG. 29, even when the next sale item 200 is in the forwardly inclined position with the movement of the pusher 50 to the rear end side, the standby support member 100 and the unloading support member 110 allow the next sale item 200 to move forward. The next sale item 200 can be supported, and the stopper portion 104 of the standby support member 100 is engaged with the front end surface of the next sale item 200, so that there is no danger of falling into the carry-out port 33. .
[0078]
Here, according to the merchandise carrying-out device, as described above, after the pusher 50 moves to the front end side, the driving of the drive source 80 is temporarily stopped, and thereafter, the movement of the pusher 50 starts to the rear end side. Therefore, the standby support member 100 and the carry-out support member 110 are swung upward after the lowest product 200 is securely carried out. Therefore, there is no danger that the standby support member 100 or the unloading support member 110 that swings upward and the lowest order product 200 will interfere with each other, and no product jam due to the mutual interference will occur.
[0079]
After the standby support driver 120 has moved to the rear end side of the mounting table portion 42, when the main plate 52 of the pusher 50 contacts the second contact piece 124 and further the first contact piece 123, Since the second contact piece 124 and the first contact piece 123 are elastically deformed and evacuated from the movement area of the main plate 52 in the pusher 50, the pusher can be moved without changing the position of the standby support driver 120. The movement to the rear end side of 50 is sequentially allowed. Further, the second contact piece 124 and the first contact piece 123 are elastically restored after the pusher 50 has passed, and again project into the movement area of the main plate 52 in the pusher 50.
[0080]
As shown in FIG. 29, when the pusher 50 moves to the rear end side of the mounting table section 42, the rear end face of the moving abutting section 722 provided on the reciprocating moving body 72 abuts on the rear pressure receiving projection 136 of the unloading support driving body 130. When the pusher 50 moves, the unloading support driving body 130 moves to the rear end side. As a result, as shown in FIG. 20, the unloading restricting portion 132 of the unloading support drive 130 is located on the upper surface of the unloading action portion 113, and the unloading support member 110 is swung up most by the unloading support drive 130. Will be retained.
[0081]
When the pusher 50 finally moves to a state in which the pusher 50 is housed in the storage recess 45, the state returns to the commodity sale standby state shown in FIG. 19 again, and this state is detected by turning off the stroke detection sensor 140. The control unit (not shown) to which the OFF signal is given from the stroke detection sensor 140 stops the movement of the pusher 50 by the drive source 80 and waits for a sales command.
[0082]
Thereafter, when a sales command is given, the above-described operation is repeatedly performed, and the commodities 200 stacked on the mounting table 42 are sequentially carried out one by one from the lower one. Although the sold-out detection lever 60 swings when the pusher 50 reciprocates, the drive source 80 for driving the reciprocating moving body 72 operates as in the first embodiment. Even when the swing of the sold-out detection lever 60 is detected, this is ignored.
[0083]
As described above, according to the commodity discharging device of the second embodiment, as the pusher 50 moves to the front end side, the pusher 50 moves upward with respect to the upper surface of the mounting table 42, and This is pushed out at a higher position with respect to the rear end surface of the lowermost product 200, and the carry-out of the lowest order product 200 becomes stable. Therefore, as shown in FIG. 30, for example, even when the thickest product 200 'is stacked on the upper surface of the mounting table portion 42, the upward movement of the pusher 50 reduces the height of the thickest product 200' to half. It becomes possible to carry out the lowermost product 200 'using the position beyond the pressing point as a pressing point, without causing a disturbance in the carrying out posture such as the front end of the lowermost product 200' being flipped up, There is no risk of causing a problem such as product clogging due to the disturbance of the carry-out posture.
[0084]
In each of Embodiments 1 and 2 described above, the pusher reciprocates with respect to the mounting table. However, it is not always necessary to reciprocate the pusher with respect to the mounting table.
[0085]
In Embodiments 1 and 2 described above, since the guide recesses extending upward toward the front end side of the mounting table are applied as means for linking the moving body and the pusher, When the moving body is moved to the front of the mounting table, the pusher can be moved forward with the upward movement of the pusher, but the guide recess necessarily extends upward toward the front end side. No need. Further, the guide projection is provided on the movable body, and the guide recess is provided in the pusher.
[0086]
【The invention's effect】
As described above, according to the commodity discharging device according to claims 1, 2, 5, 6, and 7 of the present invention, after the pusher is moved, the pusher is placed at least before the lowest commodity is discharged. , It is possible to carry out the thinnest products one by one, and at the time of carrying out a product having a height larger than the thinnest product, the pressing point of the pusher is set to 1 of the height of the product. / 2. Therefore, there is no possibility that the front end of the lowest order product is flipped up, and there is no problem such as product jam due to disturbance in the carry-out posture.
[0087]
Further, according to the commodity discharging device according to claim 3 of the present invention, as a means for linking the pusher and the moving body, a guide recess extending upward toward the front end side of the mounting table; Since a pusher having a guide projection movably engaged therein is applied, the pusher can be moved so as to protrude from the front end of the mounting table, and the lowermost product can be unloaded. Is more certain.
[0088]
Further, according to the commodity discharging device according to claim 4 of the present invention, when the lowest commodity is carried out, the height of the lowest commodity is set between the lower edge of the front end face of the next selling commodity and the upper surface of the mounting table. The pusher is moved upward so as to secure a large gap, so that when the lowest order product is moved forward from the mounting table in the forward tilted position, the next sales item may affect the lowest order product. It is possible to carry out a stable carry-out without any influence.
