Description

  The present invention relates to a product unloading device of a vending machine that cuts and unloads a product at the lowest position among products stored vertically in a lying position, and in particular, the product unloading of a vending machine that prevents the trouble of unloading the product It relates to the device.

  A conventional product vending machine of this type of vending machine is arranged at the lower part of a product passage for storing products in a vertical position and stores them in a vertical position, and holds a product at the lowest position (also referred to as sales product). A member and a second holding member that holds a product in the second position from the bottom (also referred to as a next sale product) when carrying out the product in the lowest position. The first holding member has a base end pivotally supported by a substrate that forms a wall of the product passage, and a distal end side that protrudes substantially horizontally from the substrate to the product passage (also referred to as a sales standby position) and retreats from the product passage (substrate) The tip end side is spring-biased in a direction protruding to the sales standby position. The second holding member has a base end pivotally supported by the substrate, and a distal end (product engagement portion) positioned above the pivot support point protrudes obliquely upward from the substrate to the product passage and retracts from the product passage. It is movable to a retracted position (immersed into the substrate), and the tip (product locking portion) is spring-biased in a direction to return to the retracted position (immerse into the substrate). An electromagnetic solenoid excited by a sales command having a predetermined time width and a link mechanism connected to a plunger of the electromagnetic solenoid are disposed on the back surface (the surface opposite to the product passage) of the substrate. The plunger and the link mechanism of the electromagnetic solenoid are held in a sales standby state by a return spring.

  The first holding member and the second holding member are driven by the electromagnetic solenoid via a link mechanism. In a state where the electromagnetic solenoid is not energized (sales standby state), the first holding member is locked at the sales standby position protruding into the product passage via the link mechanism to hold the sales product. On the other hand, the second holding member is spring-returned to the retracted position immersed in the substrate. When the electromagnetic solenoid is energized, the first holding member is unlocked by the link mechanism and moves toward the retracted position where the load is placed on the board due to the load of the sale product, and the sale product is carried out (the load of the sale product is removed). When it is no longer received, the spring returns to the sales standby position. At the same time, the second holding member protrudes from the retracted position immersed in the substrate via the link mechanism to the product passage and is locked at the protruding position to hold the next sale product by the product locking portion. Thereafter, when the electromagnetic solenoid is de-energized, the plunger and the link mechanism of the electromagnetic solenoid are restored by the action of the return spring, the first holding member is locked in the sales standby state, and the second holding member is returned to the retracted position. .

  As is well known, a product carry-out device of this type of vending machine is installed by assembling a product carry-out device having the same configuration in a back-to-back configuration between product passages arranged in front and back. In the product carrying-out apparatus that is paired by tying back to back, the thickness of each second holding member immersed in the substrate in the sales standby state is reduced so as not to interfere with each other. . For this reason, the width | variety arises between the board | substrate of the product holding part of the 2nd holding member and the board | substrate which the width | variety of the front-end | tip of the 2nd holding member (product locking part which locks the next sale goods) is thin, and protruded into the goods channel. . On the other hand, in the case of a soft product (for example, a beverage in a PET bottle container), the portion locked to the product locking portion of the second holding member is deformed together with the product load stacked above. Then, there is a risk that the product will be caught in the gap between the product locking portion and the substrate. When the product container bites into the gap, the second holding member cannot return to the retracted position, causing a sales trouble that the product cannot be sold even though the product remains in the product passage. In order to solve this problem, it is known that a claw portion extending in a direction opposite to the product passage is provided at the tip (product locking portion) of the second holding member so as to close the gap (for example, , See Patent Document 1). The claw portion provided in the product locking portion of the second holding member disclosed in Patent Literature 1 is assembled so as to tie the product carrying device of the same configuration back to back to form a pair, and between the second holding members Even when they are returned to the retracted position, they are configured to engage with each other without interfering with each other.

Japanese Patent No. 4396073

  In the product unloading device of the vending machine disclosed in Patent Document 1, the nail portions provided on the product latching portion of the second holding member are assembled so that the product unloading device having the same configuration is tied back to back to form a pair. Even when the second holding members are returned to the retracted position, the claws are configured so as to alternately engage with each other without interfering with each other. This is excellent in that the gap between the product locking portion of the second holding member and the substrate can be closed by the portion.

  By the way, even if the second holding members are returned to the retracted positions in the claw portion provided in the product locking portion of the second holding member as disclosed in Patent Document 1, they do not interfere with each other and do not interfere with each other. Therefore, a recess is formed between adjacent claw portions. In addition to being configured so that the gap dimension of the adjacent recesses (interval between adjacent claw parts) does not interfere with the claw part of the other-side product carry-out device that is assembled by being laid back to back, In order to avoid interference with component parts such as a link mechanism of the commodity carry-out device, the size is relatively large. For this reason, when a soft product in a container form is locked by the product support portion of the second holding member, the beverage container may be deformed and slightly bite into the recess. In this case, since the claw portion extends in the same direction as the rotation direction of the second holding member, the second holding member is moved away from the protruding position even when an edge (corner) exists on the outer edge of the claw portion. There is no hindrance when rotating toward the retracted position. However, the bottom (valley) of the recess extends so as to be orthogonal to the rotation direction of the second holding member, and is edged at the boundary between the bottom (valley) of the recess and the product locking portion. When (corner) is present, the beverage container that has bitten into the recess is caught on the edge (corner), which hinders the second holding member from rotating from the protruding position toward the retracted position. That is, even when the claw portion is provided in the product locking portion of the second holding member, the second portion is used when the beverage container slightly bites into the bottom (valley portion) of the recess formed between the adjacent claw portions. There is a possibility that the holding member cannot return to the retracted position, causing a sales trouble that the product cannot be sold even though the product remains in the product passage. In order to solve the above-mentioned problem, it is conceivable to increase the urging force of the spring for returning the second holding member. In this case, an electromagnetic solenoid as a driving device for moving the second holding member toward the protruding position is considered. Since the capacity must be increased, there is a problem that the cost increases.

Therefore, the present invention has been made in view of the above points, and the object of the present invention is to solve the problems described above and to provide a vending machine capable of smoothly selling a soft product in a container form while maintaining a thin shape. The object is to provide a commodity carry-out device.

  In order to achieve the above object, the invention according to claim 1 is characterized in that the product is supported in such a manner that the product (sales product) at the lowest position of the product passage is supported by being pivotally supported in the product passage through the opening of the substrate. A first holding member that is biased toward a projecting position projecting into the passage and movably moved to a retreat position that retreats from the product passage in a manner to release the holding of the sold product, and a product from the opening of the substrate It is pivotally supported in the passage so that it can be urged toward a retreat position where it is retracted from the product passage, and the product in the second position from the bottom of the product passage (next sale product) is locked to the product passage. A second holding member movably provided at a protruding protruding position; a link mechanism for moving the first holding member and the second holding member to a protruding position and a retracted position; and a driving means for moving the link mechanism. The second holding The material has a claw portion that extends in the opposite direction to the product passage in the product locking portion that locks the next sale product, and the claw portion ties the same configuration product carry-out device back to back to make a pair A vending machine that is assembled and configured to alternately engage with each other without interfering with each other even when the second holding members are returned to the retracted position, and a recess is formed between adjacent claws. In the product carry-out device of the machine, the valley portion in the recess has a center point on the support shaft side of the second holding member with respect to the product locking portion of the second holding member, and an edge at the boundary with the product locking portion It is characterized by a continuous curved surface without (corners).

  According to the first aspect of the present invention, the product passage is supported in such a manner that the product passage (supported product) is held in the product passage from the opening of the substrate so as to be able to move in and out of the product passage. A first holding member that is urged toward a protruding protruding position and is movable to a retreat position that retreats from the commodity passage in a manner to release the holding of the sales commodity; and an opening of the substrate to the commodity passage. It is pivotally supported so that it can be moved in and out, and is urged toward a retreat position that retreats from the product passage, and protrudes into the product passage in such a manner as to lock a product (next sale product) in the second position from the bottom of the product passage. A second holding member movably provided at the protruding position; a link mechanism that moves the first holding member and the second holding member to a protruding position and a retracted position; and a drive unit that moves the link mechanism. The second holding member will be sold next time The product locking portion for locking the product has a claw portion extending in the opposite direction to the product passage, and the claw portion is assembled so as to form a pair by tying the product carrying devices of the same configuration back to back, Further, even when the second holding members are returned to the retracted position, the vending machine is configured to carry out a product between the adjacent claw portions so as to engage with each other without interfering with each other. In the apparatus, the valley portion in the recess has a center point on the support shaft side of the second holding member relative to the product locking portion of the second holding member, and there is no edge (corner) at the boundary with the product locking portion Even when the beverage container locked to the product locking portion of the second holding member and the claw portion is deformed and bites into the valley in the recess between the adjacent claw portions due to the continuous curved surface. The trough in the recess is an edge at the boundary with the product locking part of the second holding member Since it was formed in a curved surface having no corners), since slide over the curved surface without stagnating caught beverage containers, the second holding member can return to pivot towards the retracted position. Accordingly, it is possible to smoothly sell a soft product in the form of a container while allowing the product carry-out device to be thinned.

  As shown in FIG. 2, the second holding member 9 is interposed between the left and right flanges 2 </ b> A and 2 </ b> B of the opening 21 of the substrate 2, and is supported rotatably on the second holding member shaft 105. is there. The second holding member 9 is rotated about the second holding member shaft 105, and protrudes from the opening 21 of the substrate 2 to the inside of the product passage R, and the product passage in a form that closes the opening 21. It is possible to rotate between the retracted position retracted from R. The second holding member shaft 105 is wound with a second holding member spring made of a torsion coil spring (not shown in the drawing). The second holding member 9 is always biased toward the retracted position by the elastic biasing force of the second holding member spring.

  The second holding member 9 is made of a synthetic resin (for example, polyacetal). As shown in FIG. 8A, the second holding member 9 has a pin hole 9a, a product locking portion 91 having seven claw portions 91a, and 2 The stopper portions 92 are integrally formed. The pin hole 9 a is for inserting the second holding member shaft 105. As shown in FIG. 8B, the product locking portion 91 is formed as an arcuate surface that forms the tip of the second holding member 9 and locks the next sale product. Further, the claw portion 91a is formed so as to extend from the product locking portion 91 to the opposite side of the product passage R (see FIG. 1), and when the product carry-out devices 1 and 1 having the same configuration are entangled back to back. The other product carry-out device 1 is configured to be relatively long so as to alternately engage with the claw portions 91a of the second holding member 9 without interfering with each other, and when the second holding member 9 protrudes into the product passage. The product has a function of filling a gap between the product locking portion 91 and the substrate 2.

  As described above, the claw portions 91a are alternately staggered without interfering with the claw portions 91a of the second holding member 9 in the other product carry-out device 1 when the product carry-out devices 1 and 1 having the same configuration are laid back to back. Are formed as recesses 91b (see FIG. 8B) between adjacent claw portions 91a. The bottom (valley) 91bb of the recess 91b extends in a direction intersecting the rotation direction of the second holding member 9, while the claw 91a is in the same direction as the rotation direction of the second holding member 9. It is extended. Here, when the second holding member 9 returns from the protruding position to the retracted position, an edge extending in a direction intersecting the rotation direction of the second holding member on the contact surface of the second holding member with the product ( If there is a corner), the product is caught by the edge (corner), while if the edge (corner) extends in the same direction as the rotation direction of the second holding member 9, the product is ). Therefore, even if there is an edge (corner) 91aa (see FIG. 8A) on the outer edge of the claw portion 91a extending in the same direction as the rotation direction of the second holding member 9, the product remains in the edge (corner). It does not get caught in 91aa. On the other hand, as shown in FIG. 8D (a side view corresponding to the YY cross section in FIG. 8A) shown as a comparative example (conventional device), the bottom (valley) in the recess 91b. When 91bb is cut in a straight line, an edge (corner) 91eg is formed at the boundary with the circular arc surface of the product locking portion 91, so that the product is caught on this edge (corner) 91eg. In this regard, as shown in FIG. 8C, in this embodiment, the bottom (valley) 91 bb of the recess 91 b is a second holding member than the product locking portion 91 of the second holding member 9. It is formed as a curved surface having a center point on the shaft 105 side. Further, the curved surface formed in the bottom (valley) 91bb of the recess 91b is formed so as to be continuous with the arc surface of the product engaging portion 91 without an edge (corner). Accordingly, even when a soft product in the form of a container bites into the recess 91b, the product slides on the curved surface formed on the bottom (valley) 91bb of the recess 91b, so that the second holding member 9 is restored. There is no hindrance.

  Returning to FIG. 8A, the two stopper portions 92 each have a concave sliding groove 92a and a stopper surface 92b. The concave sliding groove 92 a is slidable on the upper link shaft 101 and receives the upper link shaft 101 at the retracted position of the second holding member 9. The stopper surface 92b of the stopper portion 92 abuts on the upper link shaft 101 when the second holding member 9 protrudes into the product passage R, receives a product load applied to the second holding member 9, and causes the second holding member 9 to move. It locks in the protruding position. Further, the relief groove 9 b formed in the reinforcing material around the stopper portion 92 is formed so as not to prevent the upper link shaft 101 from entering the depth of the sliding groove 92 a of the second holding member 9. Further, the escape hole 9c is a case where the product carrying device 1 having the same configuration is laid back to back, and when each second holding member 9 is retracted to the retracted position, the stopper portion 92 of the other second holding member 9 and The reinforcing member is formed so as to prevent the thickness of the entire product carrying-out apparatus that has been entangled by escaping from the tip of the reinforcing member.

  The sold-out detection switch 10 includes a micro switch 11 and a product detection lever 12 protruding into the product passage R as shown in FIGS. As shown in an exploded view in FIG. 9, the sold-out detection switch 10 is obtained by assembling a micro switch 11 and a product detection lever 12 on a frame-shaped mounting base 13 made of a synthetic resin (for example, polyacetal). The product detection lever 12 is rotated by engaging an engagement shaft 121 projecting left and right (only one engagement shaft 121 appears in FIG. 9) with engagement holes 13 a and 13 a formed in the mounting base 13. It is pivotally supported. A pair of left and right shafts 13b, 13b projecting inward of the mounting base 13 is provided with a torsion coil spring 14 having one end locked to the mounting base 13 and the other end locked to the product detection lever 12. It is attached. The torsion coil spring 14 urges the lever piece 12a of the commodity detection lever 12 to advance toward the commodity passage R. The operation piece 12b of the product detection lever 12 is opposed to the actuator 11a of the micro switch 11, and the lever piece 12a is pushed by the product while the product is in the product passage R so as to move backward along the plane of the substrate 2. If the lever piece 12a is separated from the actuator 11a and there is no product in the product passage R (sold out state) and the spring piece 12a spring-biased by the torsion coil spring 14 advances into the product passage R, the lever piece 12a is configured to actuate the microswitch 11 by pressing the actuator 11a.

  Projections 13c are formed on the upper side and the left and right sides of the mounting base 13, respectively, and a flexible portion 13d formed in an Ω shape is formed on the lower side. The flexible portion 13d bends by applying an external force that approaches both sides from the outside of the left and right sides, and allows the sides to approach each other. When the external force is removed, both sides are returned to their original positions. It is something to return. On the other hand, although not shown in the drawing, the flange formed by cutting and raising the upper flange 2D of the substrate 2 and the right and left side edges of the opening 22 corresponds to each protrusion 13c of the mounting base 13. A locking hole is formed.

  The mounting base 13 is attached to the substrate 2 as follows. That is, the protrusion 13c formed on the upper side of the mounting base 13 is inserted into the locking hole formed in the upper flange 2D of the substrate 2, and at the same time the left and right sides are bent inward, and then formed on the left and right sides. The external force applied to the left and right sides is solved after the protrusion 13c is opposed to the locking holes formed in the left and right flanges of the opening 22 of the substrate 2. As a result, the left and right sides of the mounting base 13 are restored by the action of the flexible portion 13 d, and the protrusion 13 c is fitted into the locking holes formed in the left and right flanges of the opening 22 of the substrate 2. Note that a wiring connector 15 is connected to the microswitch 11. The wiring of the wiring connector 15 is drawn out through a wiring groove 2E formed at the left end of the substrate 2 in FIG. The wiring of the electromagnetic solenoid 5 is also laid in the wiring groove 2E.

  Next, the operation of the product carry-out apparatus will be described with reference to FIGS. In addition, in FIG. 10 to FIG. 12, a schematic configuration is shown in order to facilitate understanding of the operation of the commodity carry-out device 1.

  In the sales standby state shown in FIG. 10, the electromagnetic solenoid 5 is not energized, and the link member 61 is lowered to the lower limit position by the return spring 63 (see FIG. 2). That is, the upper link shaft 101 moves downward along the long groove 41 (see FIG. 4) of the bearing member 4, and the lower link shaft 102 moves downward along the long groove 42 (see FIG. 4) of the bearing member 4. Yes. In the sales standby state, the first holding member 7 is in the protruding position by the elastic biasing force of the first holding member spring 103a (see FIG. 2). Further, the first holding member 7 receives the load of the product G because the sale product G1 is in contact with the holding surface. Further, in the sales standby state, the rotation stopper 8 is in a protruding position by an elastic biasing force of a rotation stopper spring (not shown). Further, the rotation stopper 8 engages the small-diameter groove 73a (see FIG. 6) of the deformed groove 73 in the first holding member 7 so that the load of the product G applied to the first holding member 7 is achieved. is recieving. Further, the rotation stopper 8 is locked at the protruding position by the lower link shaft 102 engaging with the lock groove 8c (see FIG. 7). Thereby, the rotation stopper 8 locks the 1st holding member 7 in a protrusion position, and has prevented the movement to the retracted position of the 1st holding member 7. FIG. In the sales standby state, the second holding member 9 is returned to the retracted position by the elastic biasing force of the second holding member spring (not shown).

  When the electromagnetic solenoid 5 is energized by the sales command from the sales standby state shown in FIG. 10, the electromagnetic solenoid 5 attracts the plunger 51 against the elastic biasing force of the return spring 63 to raise the link member 61. Then, the lower link shaft 102 of the link member 61 is raised and the engagement of the rotation stopper 8 with the lock groove 8c is released. With this unlocking, the rotation stopper 8 is rotated toward the retracted position about the rotation stopper shaft 104 by the product load, and the support shaft 106 is also removed from the small-diameter groove portion 73a of the deformed groove 73 along with the first holding. The lock of the member 7 is released, and the first holding member 7 is rotated toward the retracted position by the product load.

  At the same time, the second holding member 9 protrudes from the retracted position toward the protruding position by the action of the upper link shaft 101 of the rising link member 61. That is, when the link member 61 rises from the sales standby state, the upper link shaft 101 engaged with the sliding groove 92a of the second holding member 9 rises. Then, the second holding member 9 moves against the elastic biasing force of the second holding member spring toward the protruding position with the second holding member shaft 105 as the center. When the link member 61 rises to the upper limit position, the upper link shaft 101 engages with the stopper surface 92b of the second holding member 9 to lock the second holding member 9. The second holding member 9 that has reached the protruding position locks the next sale product G2 by the product locking portion 91 and the claw portion 91a that closes the gap between the substrate 2 and the product locking portion 91, and the product outlet The next sale product G2 is held between the passage plate 3 and the passage plate 3. As a result, only the sales product G1 at the lowest position is carried through the first holding member 7 (see FIG. 11).

  And when the 1st holding member 7 stops receiving a merchandise load, as shown in FIG. 12, the 1st holding member 7 will return to a protrusion position (sales standby position) with the urging | biasing force of the 1st holding member spring 103a. At the same time, the rotation stopper 8 also returns to the protruding position by the elastic biasing force of the rotation stopper spring. In this case, the support shaft 106 provided at the tip of the rotation stopper 8 slides on the wall surface of the large-diameter groove portion 73b of the deformed groove 73 in the first holding member 7 and reaches the small-diameter groove portion 73a. As a result, the first holding member 7 is locked at the sales standby position.

  When the electromagnetic solenoid 5 is de-energized, the link member 61 is lowered by the biasing force of the return spring 63, so that the lock of the second holding member 9 by the upper link shaft 101 is released, and the second holding member 9 is It returns to the standby position by the urging force of the second holding member spring. When the link member 61 is lowered to the lower limit position, the lower link shaft 102 engages with the lock groove 8c of the rotation stopper 8 to lock the first holding member 7 at the sales standby position (see FIG. 10).

  Now, as shown in FIG. 11, the next holding product G2 is locked by the product locking portion 91 and the claw portion 91a in a state where the second holding member 9 is locking the next sales product G2 at the protruding position. In this state, a soft product (beverage container) in the form of a container may be deformed and bite into the recess 91b (see FIG. 8) between the adjacent claw portions 91a and 91a. As described above, in addition to being configured so that the claw portion 91a does not interfere with the claw portion 91a of the other product carry-out device 1 laid back to back, the bearing member of the other product carry-out device 1 is used. 4, since it is configured so as not to interfere with the component parts such as the link mechanism 6, the gap dimension of the recess 91b (interval between adjacent claw portions) is relatively large. For this reason, there exists a possibility that the soft goods (beverage container) of a container form may deform | transform and bite into the said recessed part 91b. Thus, when a soft product in the form of a container bites into the concave portion 91b, if the deformed beverage container is caught by the concave portion 91b, the returning operation of the second holding member 9 is hindered. In this case, since the claw portion 91a extends in the same direction as the rotation direction of the second holding member 9, an edge (corner) 91aa (see FIG. 8A) is formed on the outer edge of the claw portion 91a. Even if it does, it does not hinder the return operation of the second holding member 9, while the bottom (valley) 91 bb of the recess 91 b extends in a direction intersecting the rotational direction of the second holding member 9. Therefore, if there is an edge (corner) 91eg (see FIG. 8 (d) showing a conventional device as a comparative example) at the boundary between the bottom (valley) 91bb of the recess 91b and the product locking portion 91, the beverage The container is caught by the edge (corner) 91eg, and the returning operation of the second holding member 9 is hindered.

  In this embodiment, in this embodiment, the bottom (valley) 91bb of the recess 91b is centered on the support shaft side of the second holding member 9 with respect to the product locking portion 91 as shown in FIG. The curved surface is formed so as to be continuous with the arc surface of the product locking portion 91 without an edge (corner). For this reason, even when a soft beverage container is deformed and bites into the concave portion 91b, the beverage container slides without stagnation on the arc surface of the bottom portion (valley portion) 91bb of the concave portion 91b so that it does not get caught. Accordingly, even when a soft beverage container bites into the recess 91b, the second holding member 9 can be smoothly returned to the standby position, so that a product having a soft container form can be stably sold. It will be.

  As described above, according to the product carry-out device of the vending machine according to the embodiment of the present invention, the product passage R is pivotally supported in the product passage R from the opening 21 of the substrate 2 and is located at the lowest position of the product passage R. The product G (sales product G1) is urged toward the projecting position projecting into the product passage R in a manner to hold the product G, and moved to the retreat position in which the product G1 is released from the product passage R in a manner to release the holding of the sales product G1. The first holding member 7 that can be provided and the opening 21 of the substrate 2 are pivotally supported in the product passage R so as to be retractable and urged toward a retreat position where the product passage R is retracted, and the product passage R A second holding member 9 movably provided in a protruding position protruding in the product passage R in a manner to hold the product G in the second position from the bottom (next sale product G2), the first holding member 7 and the first holding member 7 2 Move the holding member 9 to the protruding position and the retracted position. The second holding member 9 extends in a direction opposite to the product passage R to the product locking portion 91 that holds the next sale product G2. The claw portion 91a is assembled so that the product carrying devices 1 and 1 having the same configuration are laid back to back to form a pair, and the second holding members 9 and 9 are in the retracted position. In the product carry-out device of the vending machine, which is configured so as to alternately mesh with each other without interfering with each other even when returning, and in which a concave portion 91b is formed between adjacent claw portions 91a, a trough portion in the concave portion 91b 91bb has a center point closer to the support shaft side of the second holding member 9 than the product locking portion 91 of the second holding member 9, and is continuous without an edge (corner) at the boundary with the product locking portion 91 It became the second by becoming The trough 91bb in the recess 91b can also be obtained when the beverage container locked to the product locking portion 91 and the claw 91a of the holding member 9 is deformed and bites into the trough 91bb in the recess 91b between the adjacent claw 91a. The second holding member 9 is sold next because the beverage container is hooked and slips on the arc surface without stagnation because it is formed as an arc surface without an edge (corner) at the boundary between the product holding portion 91 and the product holding portion 91 It returns to the retracted position without being blocked by the product G2. Therefore, the product carrying-out apparatus 1 can be thinned, and it is possible to smoothly sell a soft product in a container form.

  In addition, although the nail | claw part 91a in the goods carry-out apparatus of the vending machine which concerns on embodiment mentioned above demonstrated what has the edge (corner) 91aa in the outer edge, there is no edge (corner) also about the outer edge of the nail | claw part 91a.
