Description

The present invention relates to a vending machine for products such as beverage cans, and particularly relates to a vending machine provided with a manually operated product unloading mechanism capable of manually operating the product even when the power supply is stopped due to an earthquake or the like. It is a thing.

Normally, in a vending machine, products are stored in a row in a product storage passage extending in the vertical direction in the main body cabinet, and during standby, a stopper advances to the product storage passage to move the product downward. Although movement is restricted, when coins or bills are inserted, the stopper retracts to allow the product to move downward, and the moved product is discharged to the product outlet. ..
Since this stopper is driven by a solenoid driven by electric power and moves backward, the solenoid does not operate in the event of a power failure such as an earthquake, and the product cannot be taken out from the vending machine.

Recently, it has been proposed to utilize vending machines as storage warehouses to respond to disasters such as earthquakes. In response to this proposal, even when power cannot be supplied, it is automatically operated by manual operation. A vending machine equipped with a manually operated product unloading mechanism capable of taking out products from the vending machine has been developed, and this is described in Patent Document 1.
This conventional manually operated product unloading mechanism is composed of a movement conversion cam rotatably supported by a pin, a coil spring for urging the movement conversion cam in a predetermined direction, a wire connected to the movement conversion cam, and the like. By holding the operation knob connected to this wire and pulling the wire forward, the stopper is retracted to carry out the product.

A vending machine provided with a manually operated product unloading mechanism 1 according to an embodiment of the present invention will be described with reference to the drawings.
This vending machine is provided with a manually operated product unloading mechanism 1 according to the first embodiment by attaching parts to the existing vending machine 2 as a retrofit.

First, the overall configuration of the vending machine 2 and the product unloading operation will be described.
As shown in FIG. 1, reference numeral 3 indicates a main body cabinet, and the main body cabinet 3 has a box shape and has an open front surface. A plurality of product storage passages 5 are provided in the main body cabinet 3 in the left-right and front-rear directions, and the products and the beverage cans C in this embodiment are laid down in each product storage passage 5 and stacked in a row in the vertical direction. Is housed. The upper part of the product storage passage 5 is the product replenishment section 7 of the beverage can C. Further, a product discharge chute 9 is continuously provided at the lower end of the product storage passage 5.
The inner door 11 and the outer door 13 are rotatably connected to the left edge of the main body cabinet 3. When the inner door 11 is closed due to heat insulation, it faces the product storage passage 5. A product outlet 15 is provided in the lower part of the outer door 13, and the beverage can C carried out from the product storage passage 5 via the product discharge chute 9 has an opening formed in the lower part of the inner door 11 (not shown). It is discharged to the product outlet 15 of the outer door 13 through the product outlet 15.

Next, the electrically driven product unloading mechanism of the vending machine 2 will be described with reference to FIG.
Reference numeral 17 is a vertically long rectangular substrate when viewed from the rear, and as shown in FIG. 1, is arranged at the lower part on the rear surface side of the product storage passage 5 to form a part of the product storage passage 5. A large rectangular opening 19 is formed in the substrate 17.
A solenoid 21 as an electrical drive source is attached to the upper side of the rear surface of the substrate 17.

A thin-walled plunger 23 can move up and down on the solenoid 21. The solenoid 21 includes a coil portion 25 having a rectangular shape in which a coil wound around a spool is covered with an insulating resin, and a yoke portion 27 having an inverted U shape. The yoke portion 27 is formed by laminating soft iron plates, and in order to lock and fix the coil portion 25, the yoke portion 27 has a Π (pi) shape and has narrow openings facing each other in the direction in which both lower end portions approach each other. As shown in FIG. 4, screws 29 and 29 are inserted into the four corners of the yoke portion 27 and are fastened and fixed to the pedestal on the substrate 17 side. The plunger 23 projects downward from the coil portion 25, and its plate surface faces in the front-rear direction. A hooking hole 31 is formed on the lower end side of the plunger 23.
The yoke portion 27 is one step lower than the coil portion 25, and a step is formed at the boundary.
In the solenoid 21, the plunger 23 is attracted upward by excitation by energizing the coil portion 25.

Two link shafts 33 and 35 and a support shaft 37 are erected in the opening 19 of the substrate 17 in the horizontal direction in parallel with each other, and both the link shafts 33 and 35 are movable in the vertical direction. .. A spring 39 is bridged between the link shaft 35 and the support shaft 37, and the link shaft 35 is elastically urged downward.
Reference numeral 41 indicates a link member, and the link member 41 has a vertically long thin plate shape as a whole, and the upper portion thereof is bent forward to form a hook portion 43. The hook portion 43 is inserted into and connected to the hooking hole 31 formed in the plunger 23 of the solenoid 21 from the rear side. Further, a receiving portion is formed on the left and right side edges of the link member 41 by being bent vertically toward the front side, and the link shafts 33 and 35 are passed through holes provided therein.

With the above configuration, as shown in FIG. 2, the link shafts 33 and 35 are in the lower position due to the elastic urging force downward of the spring 39 when not energized, that is, when standing by, and when energized, that is, the product for sale. At the time of taking out, as shown in FIG. 6, the link shafts 33 and 35 are pulled up together with the link member 41 following the upward movement of the plunger 23 and come to the upper position. Then, when the energization is completed, it is elastically restored and returns to the lower position.

Due to the positions of the link shafts 33 and 35, the upper stopper 45 and the support link 47 retract rearward during standby and do not participate in the beverage can C, and the lower stopper 49 is in the front protruding position. It regulates the downward movement of the beverage can C placed above against its own weight.
Then, at the time of sale, as the link shafts 33 and 35 are pulled up, the upper stopper 45 and the support link 47 project into the front product accommodating aisle 5, and are between the lowermost beverage can C and the beverage can C above it. Enter and restrict the downward movement of the beverage can C above it. On the other hand, the lower stopper 49 is disengaged from the engagement support, and retreats under the weight of the beverage can C placed on the lower stopper 49. Then, the beverage can C moves downward and is carried out.

When the carry-out of the beverage can C is completed, the lower stopper 49 protrudes forward again by the elastic urging force and is maintained at that position, and the upper stopper 45 retracts so that the beverage can C resting on the lower stopper C is lowered. It falls to the side stopper 49 and rests on it to enter the standby state.
In this way, the beverage cans C are carried out one by one from the lower side.

Next, the manually operated product unloading mechanism of the vending machine 2 will be described in detail mainly with reference to FIGS. 3 to 5 and 7.
The manually operated product unloading mechanism is configured by borrowing some of the components of the electrically driven product unloading mechanism described above.
Reference numeral 51 indicates one wire, and one end of the wire 51 is attached with a crimped ball 53 that has been crimped. A grip portion 55 is attached to the other end portion.

The wire 51 is inserted into a stainless steel coil spring-shaped outer tube 57 as a protective tube, and both the caulking balls 53 and the gripping portions 55 at both ends thereof are pulled out. The wire 51 is slidable with respect to the outer tube 57, and the length of the drawer on both ends can be adjusted, but both ends are prevented from coming off by the caulking ball 53 and the grip portion 55. Even if the outer tube 57 bends due to an external action, the outer tube 57 recovers its elasticity in a straight line when the action disappears.

The wire 51 is bent in a ρ (low) shape together with the outer tube 57, and the lower side of the annular portion 59 is a U-shaped hanging portion 61. The caulking ball 53 side of the wire 51 forms a part of the annular portion 59 and faces the rear side, and the grip portion 55 side extends downward long.
The U-shaped hanging portion 61 is slackened downward, and the bottom side to the caulking ball 53 side thereof is pulled out from the outer tube 57 and exposed.
The annular portion 59 is laid on the yoke portion 27 of the solenoid 21 so as to surround the coil portion 25, but the U-shaped hanging portion 61 described above protrudes downward from the yoke portion 27. The U-shaped hanging portion 61 is lightly hooked on the hook portion 43 of the link member 41.

Reference numeral 63 indicates a thin backing plate, and the backing plate 63 has the same Π shape as the plate surface shape of the yoke portion 27. The backing plate 63 is used as a guide portion, and is overlapped with the backing portion 27 with the wire 51 and the outer tube 57 sandwiched between them.
Relief holes 65 and 65 are formed in both shoulders of the backing plate 63 so that the screws 29 and 29 can be inserted, respectively, and an insertion hole 69 for inserting the screw 67 is formed in the middle.
A stop hole 71 and a guide hole 73 are provided on one end side, that is, on the caulking ball 53 side, in a state of being arranged vertically at intervals. The wire 51 can pass through the stop hole 71 and the guide hole 73, and the caulking ball 53 cannot be inserted. Of these, the guide hole 73 is a guide hole for elastically urging the U-shaped hanging portion 61 into a U-shape in the restoring direction.
Further, the other end side is bent substantially vertically toward the yoke portion 27 side, and the bent piece 75 is also provided with a round hole 77. The hole 77 is a guide hole for elastically urging the U-shaped hanging portion 61 into a U-shape in the restoring direction, and the outer tube 57 can pass through.

The backing plate 63 has a screw 67 inserted into the insertion hole 69, further passed through the insertion hole 28 on the yoke portion 27 side, and then fastened and fixed to the pedestal on the substrate 17 side together with the yoke portion 27. By this fixing, the outer tube 57 is pressed and immovable, that is, it is maintained in a crawling posture. However, the wire 51 passing through the inside can be slid.
Since the outer tube 57 is brought close to the edge of the yoke portion 27, the backing plate 63 is raised from the yoke portion 27 by the thickness of the outer tube 57 as shown in the side view of FIG. 5 by the above fixing. However, due to the floating, both ends are inclined in a direction away from the yoke portion 27. As shown in the right side view, the plate surface of the bent piece 75 is slightly tilted with respect to the yoke portion 27, and the guide hole 77 provided there is not in the perfect vertical direction, but rather slightly. It faces in the front-back direction.

The outer tube 57 extends from the guide hole 77 with a length extending rearward and downward. The wire 51 is pulled out from the end portion to be exposed. Further, the wire 51 is pulled out from the guide hole 73 toward the rear to be exposed. A U-shaped hanging portion 61 is formed by pulling out the wire 51 from both sides. Since the guide holes 73 and 77 are oriented in the front-rear direction or the front-rear direction as described above, the outer tube 57 and the wire 51 extending from the guide holes 73 and 77 are pulled out in a direction of flipping up rearward. Since the inclination of the guide hole 77 in the front-rear direction is not so large as to secure the above-mentioned flip-up, the outer tube 57 itself maintains almost a straight shape.
The end portion on the side of the caulking ball 53 protrudes rearward through the stopper hole 71 on the upper side, and is prevented from coming off by the caulking ball 53.

With the above configuration, the link member 41 can be moved upward by pulling and lowering the U-shaped hanging portion 61 of the wire 51.
As described above, the manually operated product unloading mechanism is configured by using the components other than the solenoid 21 in the electrically driven product unloading mechanism as they are.

Next, the state of the manually operated product unloading mechanism at the time of electric drive will be described.
As shown in FIG. 6, when the link member 41 is moved upward by the electric drive by the solenoid 21, the U-shaped hanging portion 61 of the wire 51 is detached from the hook portion 43 and can be played, that is, it wraps around to the front side of the plunger 23. There is a risk of getting entangled in. However, the wire 51 is pulled out in the direction of flipping up toward the rear, and the wire 51 is difficult to bend due to the straightness maintaining characteristic of the outer tube 57, and the play is substantially restricted. Further, even when the wire 51 is carried up while being hooked on the hook portion 43, the wire 51 on the caulking ball 53 side protrudes rearward from the stop hole 71, so that the wire 51 does not bulge extremely in the left-right direction.
As described above, sufficient measures have been taken so as not to cause a failure even if a foreign substance such as a wire 51 or an outer tube 57 is incorporated into the substrate 17.
Further, since the wire 51 does not wear unless it is entangled, it can be said that the manually operated product carrying-out mechanism itself is less likely to break down.

Next, the state of the manually operated product unloading mechanism at the time of manual operation will be described.
When the outer door 13 of the vending machine 2 is opened, the grip portion 55 is exposed from below the product storage passage 5 in the main body cabinet 3. Therefore, when the grip portion 55 is grasped with a finger and pulled downward, as shown in FIG. In addition, the wire 51 slides inside the outer tube 57 and is pulled out. At the same time, the U-shaped hanging portion 61 becomes tense and pulls up the hook portion 43. By pulling up the hook portion 43, the beverage can C is subsequently taken out in the same manner as the electrically driven product carrying-out mechanism.
When the grip portion 55 is released, the elastic urging force of the spring 39 acts, and the pulled-out wire 51 on the grip portion 55 side is returned to the outer tube 57 side as shown by the arrow. At that time, since the outer tube 57 tries to return from the solid line to the straight shape as shown by the broken line as shown in the enlarged view, this straightness maintenance characteristic is also utilized, and the wire 51 is a loose U-shaped hanging portion. Return to 61. Therefore, the link member 41 quickly descends and returns to the lower position during standby as shown in FIG. The existing vending machine 2 has different elastic urging force of the spring 39 depending on the manufacturer, but by using the outer tube 57 that also serves as this protective tube, regardless of the type of vending machine 2, the product can be manually operated. After taking it out, it is possible to use the product unloading mechanism by electric drive again more reliably.

Further, the parts to be added as the manually operated product carry-out mechanism are the wire 51, the outer tube 57, and the backing plate 63, which can be easily attached by tightening the screws. , The number of parts is small, and the installation work is easy.

Next, the manually operated product unloading mechanism 79 according to the second embodiment will be described with reference to FIGS. 8 to 10.
The manually operated product unloading mechanism 79 is also configured by attaching parts to the existing vending machine 2 as a retrofit, like the manually operated product unloading mechanism 1 according to the first embodiment. Hook-shaped guide portions 83, 83 of the wiring cord 81 arranged below the coil portion are used. The wiring cord 81 is lifted and supported in the left-right direction by the hook-shaped guide portions 83, 83 so as not to interfere with the plunger 23. The parts common to the manually operated product unloading mechanism 1 are designated by the same reference numerals, and the description thereof will be omitted.
In the manually operated product unloading mechanism 1, the hook-shaped guide portions 83 and 83 are not shown as constituent elements, so that they are not shown, but in the manually operated product unloading mechanism 79, they are shown.

Hereinafter, the guide portion of the manually operated product unloading mechanism 79 will be described in a state of being viewed from the rear. A plate-shaped bracket member 85 is used for this guide portion. The bracket member 85 has an inverted L shape, and the end portion of the upper horizontal portion 87 thereof is bent substantially vertically to form a projecting piece 89. Further, in the vertical portion 91 connected to the left end portion of the upper horizontal portion 87, two cut edges are formed in the intermediate portion thereof in the horizontal direction and the vertical direction, respectively, and the cut edge and the vertical portion 91 are formed. The upper end of the rectangular portion surrounded by one edge of the above is bent substantially vertically to form the projecting piece 93. Further, a notch is also made in the horizontal direction at the lower end of the vertical portion 91 to form one notch edge, and the right end portion of the rectangular portion surrounded by the notch edge and the two edges of the vertical portion 91 is formed. It is bent substantially vertically to form a projecting piece 95. The projecting piece 95 extends to the right and is wider than the other vertical portions 91.

The projecting pieces 89, 93, and 95 all project rearward, the plate surface of the projecting piece 89 faces in the left-right direction, and the plate surface of the projecting piece 93 faces in the vertical direction. , The plate surface of the projecting piece 95 faces in the left-right direction.
Guide holes 97 and 99 through which the outer tube 57 is inserted are formed in the projecting pieces 89 and 93, respectively. Further, the projecting piece 95 is formed with a guide hole 101 through which the wire 51 is inserted and a stop hole 103.
Further, an insertion hole 105 and an escape hole 107 for inserting a screw 67 are formed in an intermediate portion and a corner portion of the upper horizontal portion 87, respectively.

Yet another bracket member 109 is used for this guide portion. The bracket member 109 has an I-shape, and a projecting piece 111 for bending extends from the lower end portion thereof. The projecting piece 111 is bent substantially vertically toward the rear. The crease of the projecting piece 111 is slanted and descends to the right.
The plate surface of the projecting piece 111 faces the lower left upper right direction.
A guide hole 113 through which the outer tube 57 is inserted is formed in the projecting piece 111.
Further, an insertion hole 115 for inserting the screw 67 is formed at the upper end portion.

Similar to the backing plate 63, the guide portion is formed in a Π shape by the combination of the two bracket members 85 and 109, and the guide portion is applied to the yoke portion 27 from the rear and overlapped.
Screws 67 are inserted into the insertion holes 105 and 115 of the bracket members 85 and 109, and after being passed through the insertion holes 28 (FIG. 4) on the yoke portion 27 side, the yoke portions 27 are fastened and fixed to the pedestal on the substrate 17 side. ing. Further, the escape hole 107 is designed so that a screw 29 for tightening and fixing the yoke portion 27 can be inserted.

The wire 51 is bent in a ρ shape together with the outer tube 57, and the outer tube 57 is inserted into the guide holes 113, 97, 99. The outer tube 57 is kept immovable with respect to the guide holes 113, 97, 99, that is, in a crawling posture. However, the wire 51 passing through the inside can be slid. The wire 51, which is pulled out from the outer tube 57 and forms the U-shaped hanging portion 61, is inserted into the guide hole 101 and the stop hole 103 and is prevented from coming off by the caulking ball 53.

In this way, the outer tube 57 and the wire 51 are crawled in the same manner as the manually operated product carrying-out mechanism 1, but the outer tube 57 inserts the guide hole 113 toward the lower left, and the wire 51 is the guide hole 101. Is inserted toward the right, and is urged in the V-shaped direction with respect to the U-shaped hanging portion 61. On the other hand, in the manually operated product unloading mechanism 1, the U-shaped hanging portion 61 is urged in the rearward flip-up direction. As described above, although there are differences in the urging direction, all of them are in the direction of elastically restoring to a U shape.
However, the guide hole 101 and the stop hole 103 of the wire 51 are formed in the projecting piece 95, and are devised so that the movement of the wire 51 passing between the guide hole 101 and the stop hole 103 is not obstructed by the outer tube 57. There is.
Further, the outer tube 57 and the wire 51 are inserted after the guide portion is fixed to the solenoid 21 side, which facilitates the mounting work.

In FIG. 11, reference numeral 117 indicates a shield piece. The shield piece 117 is made of a thin plastic sheet, and a horizontally long rectangular hanging hole 119 is formed by punching on the upper side for hanging. Further, the lower intermediate portion is notched in a rectangular shape in order to expose the hooking hole 31 of the plunger 23 to form a notch portion 121. The size of the notch 121 is adjusted to accommodate the upper limit of the upward movement of the plunger 23. Both the left and right sides are widened to the outside so as not to interfere with the guide of the wiring cord 81.
As shown in FIG. 12, when the hook-shaped guide portions 83 and 83 are hung through the hanging holes 119 of the shield piece 117, the seat surface covers the plunger 23 and the left and right spaces and shields from the rear.

After suspending the shield piece 117, the wiring cord 81 is hung on the hook-shaped guide portions 83, 83 to guide the shield piece 117, and the wiring cord 81 also acts to press the shield piece 117 to prevent it from coming off.
The U-shaped hanging portion 61 of the wire 51 hangs down on the rear surface side of the shield piece 117, and even if the wire 51 is loosened, the wraparound to the plunger 23 side is restricted.

Since the wire 51 of the manually operated product carrying-out mechanism 79 is inserted into the guide hole 101 and the stop hole 103 in a state where it is sufficiently pulled out from the outer tube 57 and the caulking ball 53 is attached, the U-shaped hanging portion 61 is the plunger 23. It is extremely widened beyond the left and right sides of the above, and may exceed the restoration limit of the above-mentioned elastic restoration means.
Normally, at the final stage of the installation work, while pressing the U-shaped hanging portion 61 with one hand, the grip portion 55 is grasped with the other hand and the wire 51 is pulled to tension the plunger 23 once. The degree of slack is adjusted while being careful not to wrap around to the side, but this work may be forgotten. In this case, when the manually operated product unloading mechanism 79 is operated for the first time, the wire 51 of the U-shaped hanging portion 61 is pulled from a greatly loosened state, but by using the shield piece 117 together, , The wire 51 of the U-shaped hanging portion 61 does not wrap around to the plunger 23 side. That is, even without this final slack adjustment work, the wire 51 is surely prevented from wrapping around to the plunger 23 side.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and the invention can be made even if there is a design change within a range not deviating from the gist of the present invention. included.

According to the vending machine of the present invention, a vending machine provided with an electrically driven product unloading mechanism can be retrofitted with a manually operated product unloading mechanism.
