FIG. 34 is an explanatory view showing a state where the shaft portion of the product guide plate is inserted into the large diameter portion of the mounting hole of the side plate. FIG. 34 shows the shaft portion of the product guide plate used in the product storage shelf of the conventional vending machine. FIG. 35 is a partial plan view of a product storage shelf of a conventional vending machine.

  A product storage shelf 1 of a conventional vending machine shown in FIGS. 27 to 35 includes a pair of side plates 2 facing each other and a plurality of arc-shaped product guide plates 3 supported between the side plates 2. A plurality of meandering product guide passages 4 extending in the vertical direction with the product guide plates 3 facing each other are formed.

  Each merchandise guide passage 4 is configured to store the merchandise thrown in from the upper end in the vertical direction, and the merchandise delivery mechanism 5 provided at the lower end side drops and carries out the merchandise one by one downward. It has become.

  Each side plate 2 has a large number of mounting holes 2a for supporting each product guide plate 3, and each mounting hole 2a has a large-diameter portion (shaft insertion portion) 2b and a small-diameter portion (shaft member) formed in communication in the vertical direction. Joint portion) 2c. Each product guide plate 3 has a shaft portion 3a projecting on both sides in the width direction at the upper end, and an enlarged portion 3b enlarged in a flange shape is formed at the tip of each shaft portion 3a.

  In this case, in the mounting hole 2a of each side plate 2, the large diameter portion (shaft insertion portion) 2b is larger than the enlarged portion 3b at the tip of the shaft portion 3a of the product guide plate 3, and the small diameter portion (shaft engagement portion) 2c. Is larger than the outer diameter of the shaft portion 3a and smaller than the enlarged portion 3b, and the width W is between the large diameter portion (shaft insertion portion) 2b and the small diameter portion (shaft engagement portion) 2c. A narrow portion 2d slightly narrower than the diameter of the portion 3a is formed.

  Further, the shaft portion 3a and the enlarged portion 3b of each product guide plate 3 are provided integrally with the product guide plate 3, and are formed by the following method.

  That is, as shown in FIG. 31, a protruding portion 6 a that protrudes on both sides in the width direction is provided on one end side of the plate material 6 that becomes the product guide plate 3, and a plurality of pieces that extend in the width direction of the plate material 6 are provided on the tip side of the protruding portion 6 a. A cut 6b is formed.

  Then, by bending one end side (shaded portion in the figure) of the plate member 6 including the protruding portion 6a into a circular cross section, as shown in FIG. 32, the shaft portion 3a is formed and the tip end side of the protruding portion 3a is The enlarged portion 3b is formed by separating each of the cuts 3b and bending the shaft portion 3a outward in the radial direction.

  As a result, the enlarged portion 3b is locked to the side plate 2 to restrict movement of the shaft portion 3a in the axial direction, and the shaft portion 3a is locked to the small width portion 2d to restrict movement to the large diameter portion 2b. Is done.

  For this reason, each product guide plate 3 is provided without requiring a separate regulating member for restricting the movement of the shaft 3a once moved to the small diameter portion (shaft engagement portion) 2c to the large diameter portion (shaft insertion portion) 2b. It can be attached between the side plates 2 and the attachment work can be performed very easily.

JP-A-9-62926

  The product storage shelf disclosed in Patent Document 1 inserts the shaft portion 3a of each product guide plate 3 into the mounting hole 2a of the side plate 2, and the shaft portion 3a has a large diameter portion (shaft insertion portion) of the mounting hole 2a. The movement of the shaft portion 3a in the axial direction is regulated by sliding the 2b from the small diameter portion (shaft engaging portion) 2c and locking the enlarged portion 3b provided at the tip of the shaft portion 3a to the side plate 2. is there.

  However, the small width portion 2d provided between the large diameter portion (shaft insertion portion) 2b and the small diameter portion (shaft engagement portion) 2c is passed through the shaft portion 3a by press fitting, and the small diameter portion (shaft engagement portion) 2c is passed through. Since the movement of the moved shaft portion 3a to the large-diameter portion (shaft insertion portion) 2b is restricted, the relative dimensional variation between the shaft portion 3a and the small width portion 2 or the shaft portion 3a and the small width portion 2 Due to the ease of deformation, the force required for sliding movement from the large diameter portion (shaft insertion portion) 2b of the shaft portion 3a to the small diameter portion (shaft engagement portion) 2c tends to vary.

  Therefore, when it can move to the small diameter part (shaft engagement part) 2c with a force smaller than the design, the shaft part 3a may return to the large diameter part (shaft insertion part) 2b due to impact or the like, and the small diameter part (shaft engagement) If a larger force than the design is required to move to the joint portion 2c, the mounting operation becomes difficult.

  Further, since the force required for sliding movement from the large diameter portion (shaft insertion portion) 2b of the shaft portion 3a to the small diameter portion (shaft engagement portion) 2c is likely to vary, the side plate There is a possibility that the second mounting hole 2a or the shaft portion 3a is deformed.

  Further, the force necessary to return the shaft portion 3a once moved to the small diameter portion (shaft engagement portion) 2c to the large diameter portion (shaft insertion portion) 2b is larger than the shaft portion 3a. Part) 2b tends to be smaller than the force required for sliding movement from the small diameter part (shaft engaging part) 2c.

  Therefore, in view of the above-described conventional problems, the present invention hardly causes variations in the force required to engage the shaft body with the shaft engaging portion of the mounting hole of the side plate, and the shaft body engaged with the shaft engaging portion is The force required to return to the shaft insertion part can be greater than the force required to engage the shaft body with the shaft engagement part, and the shaft body engaged with the shaft engagement part can be freely inserted by the impact or the like. An object of the present invention is to provide a product storage shelf for a vending machine capable of extremely reducing the possibility of returning to a section, stabilizing assembly quality, and improving productivity.

  A merchandise storage shelf of a vending machine to which the present invention is applied includes a plurality of merchandise guide plates provided with a shaft body projecting on both sides in the width direction and having an outer diameter of an engagement position smaller than an outer diameter of a tip portion, and the shaft body Having a mounting hole comprising a shaft insertion portion that can be inserted from the tip portion to the engagement position and a shaft engagement portion that is smaller than the outer diameter of the tip portion and that can be engaged with the shaft body at the engagement position. Then, the shaft body inserted from the tip portion to the engagement position in the shaft insertion portion is slid in the direction of the shaft engagement portion to engage the shaft body with the shaft engagement portion. A product storage shelf of a vending machine comprising a pair of side plates for pivotally supporting the product guide plates, wherein a plurality of the product guide plates are mounted on the pair of side plates so that a product guide passage is formed between the pair of side plates. It is.

  In order to achieve the above object, the present invention is substantially perpendicular to the plate surface of the side plate by being pushed by the distal end portion of the shaft body that is inserted into the shaft insertion portion and slides in the direction of the shaft engagement portion. When the shaft body inserted into the shaft insertion portion up to the engagement position is slid so as to engage with the shaft engagement portion, An elastic stopper that prevents the shaft body from moving to the shaft insertion portion by elastically returning to a position close to the shaft insertion portion due to the loss of contact with the shaft insertion portion is provided on at least one of the side plates of the pair of side plates. It was formed integrally.

The elastic stopper has a free end at an end closer to the shaft engaging portion and a fixed end connected to a plate surface of the side plate at an end far from the shaft engaging portion. Covering at least a part of.

Further, the elastic stopper is a cut and raised piece formed on the side plate, and covers at least a part of the shaft insertion portion at a position away from the plate surface of the side plate in the insertion direction of the shaft body, The end closer to the shaft engaging portion is inclined so as to approach the plate surface of the side plate as it approaches the shaft engaging portion.

  In the present invention, the elastic stopper configured as described above is provided so that the shaft body engaged with the shaft engaging portion does not return to the shaft insertion portion without permission due to an impact or the like. The shaft body provided on the side plate is inserted into the shaft insertion portion of the mounting hole of the side plate until the shaft body engages with the shaft engagement portion. Since it is pushed and elastically deforms away from the shaft insertion portion in a direction substantially perpendicular to the plate surface of the side plate, it is necessary to engage the shaft body with the shaft engaging portion of the mounting hole of the side plate. The force can be made relatively small, and the variation in force required to engage the shaft body with the shaft engaging portion can be made relatively small.

  The elastic stopper configured as described above is substantially perpendicular to the plate surface of the side plate when the shaft inserted into the shaft insertion portion to the engagement position is slid so as to engage with the shaft engagement portion. When the elastic stopper is pushed away from the shaft insertion portion in any direction, the shaft body is elastically returned to a position close to the shaft insertion portion by eliminating contact with the tip portion of the shaft body. Since the movement to the insertion portion is prevented, the shaft engagement portion is engaged with the shaft body with a force necessary to return the shaft body engaged with the shaft engagement portion to the shaft insertion portion. Therefore, it is possible to greatly reduce the possibility that the shaft body engaged with the shaft engaging portion will return to the shaft insertion portion without permission due to an impact or the like.

  This stabilizes the assembly quality of the product storage shelf and improves productivity.

  According to the present invention, the force required to engage the shaft body with the shaft engaging portion of the mounting hole of the side plate is relatively reduced by the elastic stopper formed integrally with at least one side plate of the pair of side plates. In addition, the variation in force required to engage the shaft body with the shaft engaging portion can be made relatively small. Furthermore, the force required to return the shaft body engaged with the shaft engaging portion to the shaft insertion portion can be larger than the force required to engage the shaft body with the shaft engaging portion. The possibility that the engaged shaft body will return to the shaft insertion part by impact or the like can be extremely reduced.

  This makes it possible to easily assemble a product storage shelf with stable quality, so that it is possible to provide an inexpensive product storage shelf and vending machine with stable quality.

Explanatory drawing which shows the state which slid the shaft part of the product guide plate used for the product storage shelf of the conventional vending machine to the small diameter part of the mounting hole of the side plate. Partial plan view of a product storage shelf of a conventional vending machine

According to a first aspect of the present invention, there are provided a plurality of product guide plates each provided with a shaft body projecting on both sides in the width direction and having an outer diameter at an engagement position smaller than an outer diameter of the tip portion; A mounting hole including a shaft insertion portion that can be inserted to a position and a shaft engagement portion that is smaller than an outer diameter of the tip portion and that can be engaged with the shaft body at the engagement position, and the shaft insertion portion includes the mounting hole. A pair for locking the product guide plate by sliding the shaft inserted from the tip portion to the engagement position in the direction of the shaft engagement portion to engage the shaft body with the shaft engagement portion. A product storage shelf of a vending machine in which a plurality of the product guide plates are mounted on the pair of side plates so that a product guide passage is formed between the pair of side plates, the shaft insertion portion Inserted into the shaft and slid in the direction of the shaft engaging portion. The shaft body, which is elastically deformed so as to be separated from the shaft insertion portion in a direction substantially perpendicular to the plate surface of the side plate, is slid so as to be engaged with the shaft engagement portion. An elastic stopper that prevents the shaft body from moving to the shaft insertion portion by elastically returning to a position close to the shaft insertion portion by eliminating contact with the tip portion when the pair of side plates is disposed. The elastic stopper is formed integrally with at least one of the side plates, and the elastic stopper has a free end at the end closer to the shaft engaging portion and an end portion far from the shaft engaging portion at the plate surface of the side plate. It is a connected fixed end and covers at least a part of the shaft insertion part, and the elastic stopper is a cut-and-raised piece formed on the side plate in the insertion direction of the shaft body from the plate surface of the side plate. The shaft insertion part It covers at least a part, and the end closer to the shaft engaging portion is inclined so as to approach the plate surface of the side plate as it approaches the shaft engaging portion. Yes, an elastic stopper can be formed by the cut and raised pieces formed on the side plate.

In the configuration described above, the elastic stopper having the configuration described above is provided so that the shaft body engaged with the shaft engaging portion does not return to the shaft insertion portion without permission due to an impact or the like. The shaft body provided on the side plate is inserted into the shaft insertion portion of the mounting hole of the side plate until the shaft body engages with the shaft engagement portion. Since it is pushed and elastically deforms away from the shaft insertion portion in a direction substantially perpendicular to the plate surface of the side plate, it is necessary to engage the shaft body with the shaft engaging portion of the mounting hole of the side plate. The force can be made relatively small, and the variation in force required to engage the shaft body with the shaft engaging portion can be made relatively small.

  The elastic stopper configured as described above is substantially perpendicular to the plate surface of the side plate when the shaft inserted into the shaft insertion portion to the engagement position is slid so as to engage with the shaft engagement portion. When the elastic stopper is pushed away from the shaft insertion portion in any direction, the shaft body is elastically returned to a position close to the shaft insertion portion by eliminating contact with the tip portion of the shaft body. Since the movement to the insertion portion is prevented, the shaft engagement portion is engaged with the shaft body with a force necessary to return the shaft body engaged with the shaft engagement portion to the shaft insertion portion. Therefore, it is possible to greatly reduce the possibility that the shaft body engaged with the shaft engaging portion will return to the shaft insertion portion without permission due to an impact or the like.

  This makes it possible to easily assemble a product storage shelf that is stable in quality, so that an inexpensive product storage shelf and vending machine can be provided.

  It should be noted that the elastic stopper is effective even if it is formed on one of the side plates of the pair of side plates, but is more reliable if formed on both of the side plates. However, when the elastic stopper is formed on both the side plates, the manufacturing cost is higher than when the elastic stopper is formed on one of the side plates. Therefore, whether the elastic stopper is formed on both the pair of side plates or one of the side plates may be selected according to the manufacturing cost effectiveness.

  With the above configuration, the shaft is inserted into the shaft insertion portion and is slid in the direction of the shaft engagement portion, and is pushed by the tip portion of the shaft body so as to be separated from the shaft insertion portion in a direction substantially perpendicular to the plate surface of the side plate. When the shaft body inserted into the shaft insertion portion to the engagement position is slid so as to engage with the shaft engagement portion, contact with the tip portion is eliminated. It is possible to easily form an elastic stopper integrally with the side plate, which elastically returns to a position close to the portion and prevents the shaft body from moving to the shaft insertion portion.

  The elastic stopper has a free end at the end closer to the shaft engaging portion and a fixed end connected to the plate surface of the side plate at the end far from the shaft engaging portion. The distance between the free end and the fixed end of the elastic stopper can be made as large as the outer diameter of the shaft body, and the place pushed by the tip of the shaft body is a place relatively close to the free end. Thus, the elastic deformation and the elastic return of the elastic stopper can be realized without difficulty.

  The elastic stopper has a free end at the end closer to the shaft engaging portion and a fixed end connected to the plate surface of the side plate at the end far from the shaft engaging portion. The amount of elastic deformation of the elastic stopper can be gradually changed according to the sliding movement of the shaft body from the shaft insertion portion to the shaft engaging portion.

  Further, the elastic stopper is provided so that the force required to return the shaft body engaged with the shaft engaging portion to the shaft insertion portion is shortened by a predetermined amount from the fixed end to the free end of the elastic stopper. The force required to deform the shaft can be set to a force required to return the shaft body engaged with the shaft engaging portion to the shaft insertion portion. Since the force required to engage the shaft body with the portion can be considerably larger, there is a high possibility that the shaft body engaged with the shaft engagement portion will return to the shaft insertion portion without permission due to an impact or the like. Less.

Further, the inclined portion of the end portion of the elastic stopper that is closer to the shaft engaging portion is a portion that is pushed by the tip portion of the shaft body, and the elastic stopper that is closer to the shaft engaging portion. The portions other than the inclined portion of the end portion are not easily pushed by the tip portion of the shaft body, and the elastic deformation of the elastic stopper and the elastic return are performed while increasing the amount of elastic deformation of the elastic stopper. It can be realized smoothly without difficulty.

  Further, since the elastic stopper is easily elastically deformed in accordance with the sliding movement of the shaft body from the shaft insertion portion to the shaft engaging portion, the shaft engaging portion of the mounting hole of the side plate has the shaft. The force required to engage the body can be made relatively small, and the place where the elastic stopper is pushed by the tip end portion of the shaft body is limited to a small size, so that the shaft insertion portion of the shaft body The amount of elastic deformation of the elastic stopper can be gradually changed in accordance with the sliding movement to the shaft engaging portion.

According to a second invention, in the first invention, a flange portion having an enlarged outer diameter is formed at the tip portion that pushes the elastic stopper, and the shaft of the elastic stopper is restored when the elastic stopper is elastically restored. The shaft moves to the shaft insertion portion at a position closer to the plate surface of the side plate on which the elastic stopper is formed than the flange portion (the product guide passage side). It is characterized by preventing this.

  With the above configuration, after the elastic stopper is elastically restored by the sliding movement of the shaft body to the shaft engagement portion, the shaft body engaged with the shaft engagement portion may return to the shaft insertion portion. The end of the elastic stopper closer to the shaft engaging portion is closer to the plate surface of the side plate on which the elastic stopper is formed than the flange portion (on the product guide passage side). The force that the shaft body engaged with the shaft engaging part tries to return to the shaft inserting part is prevented from moving to the shaft inserting part, and the force toward the center of the longitudinal direction of the shaft body (the Even if it works to move the end closer to the shaft engaging portion of the elastic stopper to the product guide passage side), the tip of the shaft body is pushed in the direction pushing the elastic stopper. The shaft in the elastic stopper Not work to move the end portion closer to the engaging portion.

  Therefore, the force required to return the shaft body engaged with the shaft engaging portion to the shaft insertion portion is reduced by a predetermined amount from the fixed end to the free end of the elastic stopper. The force required to deform the shaft and can be considerably larger than the force required to engage the shaft body with the shaft engaging portion, so that the shaft body engaged with the shaft engaging portion is The possibility of returning to the shaft insertion part without permission can be extremely reduced.

According to a third aspect of the present invention, in the second aspect , the tip portion that presses the elastic stopper has a hollow cylindrical shape and the flange portion extends in a flare shape, and is closer to the shaft engaging portion in the elastic stopper. The width of the end portion is narrower than the inner diameter of the tip portion, and the elastic stopper includes an inclined tip portion of the elastic stopper and an inner peripheral surface of the shaft body that slides from the shaft insertion portion to the shaft engaging portion. It is characterized in that it returns elastically immediately after the elastic deformation becomes the largest due to contact.

  In the above-described configuration, the tip portion that presses the elastic stopper has a hollow cylindrical shape, the flange portion spreads in a flare shape, and the width of the end portion closer to the shaft engaging portion in the elastic stopper is the tip portion. Since the end closer to the shaft engaging portion of the elastic stopper enters the inside of the tip pushing the elastic stopper, the tip of the elastic stopper is inclined. And the inner peripheral surface of the shaft body slidingly moving from the shaft insertion portion to the shaft engagement portion, the end portion of the elastic stopper that is closer to the shaft engagement portion is gradually pushed out, and the elasticity It can be easily configured to return elastically immediately after the elastic deformation of the stopper is maximized (the restoring force for elastic recovery is maximized).

Therefore, the position of the end portion closer to the shaft engaging portion in the elastic stopper when the elastic stopper is elastically restored is positioned closer to the center in the longitudinal direction of the shaft body with a margin than the flange portion. The end of the elastic stopper closer to the shaft engagement portion is closer to the center in the longitudinal direction of the shaft body than the flange portion, and the shaft body is inserted into the shaft insertion portion. Can be more reliably prevented.

According to a fourth invention, in any one of the first to third inventions, the shaft body is provided at a plurality of locations in a direction of guiding a product on the product guide plate, and the elastic stopper is the plurality of the product guide plates. The shaft body is provided for the mounting hole into which at least one of the shaft bodies is inserted, and the shaft body is provided at a plurality of locations in the product guide plate in the direction of guiding the product. If the product guide plate is particularly rigid and the product guide plate is difficult to deform in the direction of guiding the product, at least one of the shafts at the plurality of locations of the product guide plate. If the elastic stopper is provided for the mounting hole into which the shaft body is inserted, the effect of any one of the first to fifth inventions can be obtained.

According to a fifth invention, in any one of the first to fourth inventions, a plurality of the product guide plates are connected by the shaft body in a direction in which a product is guided to form an assembly, and the elastic stopper is the assembly The product is provided to the mounting hole into which at least one of the shaft bodies in the direction of guiding the product of the body is inserted, and the plurality of product guide plates guide the product. When the assembly is formed by being connected by the shaft body in the direction to perform, particularly when the assembly is difficult to deform in the direction in which the product is guided, the plurality of locations in the direction in which the product of the assembly is guided If the elastic stopper is provided for the mounting hole into which at least one of the shaft bodies is inserted, the effect of any one of the first to sixth inventions can be obtained.

The spring 27 is a product guide plate in which the coil portion 27a is aligned with the half curl pieces 20a to 20c, the full curl pieces 21a to 21c, and the curl portions 25a and 25b, and the first arm portion 27b is arranged on the upper side. 13, the second arm portion 27c is arranged on the outer peripheral surface 13c side so as to be in a positional relationship so as to hit the back side of the flapper 14.

  When the structure 71 with the flapper is assembled, the curl portions 25a and 25b are provided in the support shaft insertion portion 25 of the flapper 14 between all the curl pieces 21a and 21b or, if necessary, between all the curl pieces 21b and 21c. A coil portion 27a of the spring 27 is disposed between the two, and is coaxially inserted and supported by the shaft body 16, but the outer peripheral surface of the product guide plate 13 in which the first arm portion 27b is disposed on the upper side at the same time The second arm portion 27c is assembled on the 13c side so as to be in a positional relationship so as to hit the back side of the flapper 14.

  In the structure 71 with the flapper assembled as described above, the support shaft insertion portion 25 and the spring 27 of the flapper 14 are arranged in the length direction of the shaft body 16 between all the curl pieces 21a and 21b or between all the curl pieces 21b and 21c. By being movable, when the structural body 70 or the structural body 71 with the flapper is connected to the lower side of the structural body 71 with the flapper, the fitting space of the half curl portion 20 does not exist on the shaft body 16.

In the above configuration, after confirming the positions of the half curl pieces 20a to 20c of the structure 70 or the structure 71 with the flapper attached below, the support shaft insertion portion 25 of the flapper 14 on the shaft body 16 and the appropriate spring 27 After being moved to the position, the half-curl pieces 20a to 20c are fitted and connected to the shaft body 16 formed in the upper structure 71 with the flapper.

  In order to eliminate the movement adjustment of the support shaft insertion portion 25 and the spring 27 of the flapper 14 on the shaft body 16 to an appropriate position and further improve the productivity, the support shaft insertion portion 25 of the flapper 14 is fully curled. A device that does not move on the shaft body 16 between the pieces 21a and 21b or all the curled pieces 21b and 21c is required.

  As one method, the cross-sectional shape of the curl portions 25a and 25b in the support shaft insertion portion 25 of the flapper 14 is an arc that is longer than ½ of the circumference and smaller than 3/4, like the half curl portion 20. The clearance between the back surface of the flapper 14 and the respective ends of the curled portions 25a and 25b is secured, and the curled portion 25a is mounted at a position where the curled portions 25a and 25b are attached to the shaft body 16. A protruding portion that protrudes in a hemispherical shape from the center of the shaft body 16 in the circumferential direction to a position corresponding to the curled portion 25b side and the curled portion 25a side of the curled portion 25b is in the region Y2 shown in FIG. 9B. Two places are provided on the shaft 16 as a shape to be accommodated.

With the above configuration, after inserting the spring 27 through the shaft body 16 coaxially with the entire curled portion 21 provided at the lower end of the product guide plate 13, the spring 27 is positioned between the two protruding portions, and the two protruding portions curled portion 25a to the outside between the curl portion 25a at a position 25b is disposed, 25b and the pressing from the gap to the shaft 16 formed by the curled portion 25a, it is fitted to shaft 16 by utilizing the elastic deformation of 25b The flapper 14 is pivotally mounted.

  The curled portions 25 a and 25 b do not move on the shaft body 16 by the two protruding portions, and the support shaft insertion portion 25 of the flapper 14 maintains an appropriate position on the shaft body 16. As described above, the height of the two protrusions provided on the shaft body 16 is a shape that fits within the area Y2 shown in FIG. 9B. However, the height can be further inserted into the coil portion 27a of the spring 27. Must.

  The spring 27, which is a torsion spring, obtains an urging force by using a restoring force due to a reduction in the angle formed by the first arm portion 27b and the second arm portion 27c in a normal operation, and the diameter of the coil portion 27a is reduced according to the reduction in the angle. The diameter is set to be larger than the diameter of the shaft body 16 in anticipation of being reduced by elastic deformation. Therefore, it is possible to provide a protrusion on the shaft body 16 with respect to the spring 27 as well.

  Another method is to fix the position of the spring 27 and fix the position of the support shaft insertion portion 25 on the shaft body 16 via the spring 27. First, the coil portion 27a of the spring 27 is formed by bending a steel wire (linear body) into a circular shape. At that time, the length of the coil portion 27a formed by spirally bending the steel wires without contacting each other is curled. It is made substantially equal to the distance between 25a and the curl part 25b.

  A cut-and-raised portion for fixing the first arm portion 27 b in contact with the outer peripheral surface 13 c at the lower part of the product guide plate 13 is formed on the product guide plate 13. This cut-and-raised shape has a shape whose cross section is cut into a substantially triangular shape toward the outer peripheral surface 13c, and the first arm portion 27b can be inserted from below to above. As a result, the position of the first arm portion 27b in the left-right width direction of the shaft body 16 or the product guide plate 13 is fixed, and the position of the spring 27 in the width direction is fixed.

  Since the length of the coil part 27a described above is substantially equal to the distance between the curl part 25a and the curl part 25b, if the coil part 27a of the spring 27 is disposed between the curl part 25a and the curl part 25b, the support shaft insertion part 25, the position of the shaft body 16 or the product guide plate 13 in the left-right width direction is fixed.

By configuring the assembly 30 as described above, the two product guide plates 13 and 13, the flapper 14, and the spring 27 are arranged at the location where the structure 70 and the structure 71 with a flapper are connected. All the curl pieces 21a to 21c of the product guide plate 13 arranged on the upper side, the half curl pieces 20a to 20c of the product guide plate 13 arranged on the lower side, the curl portions 25a and 25b of the flapper 14, and the spring 27 The shaft body 16 is inserted through the coil portion 27a.

  Here, as shown in FIG. 13, the shaft body 16 has a hollow shaft body portion 16 a that is linear and extends linearly, and is directed radially outward of the shaft body portion 16 a on one end side of the shaft body portion 16 a. And has a flange portion 16b that is expanded. The shaft main body 16a is slightly smaller than the width of the product guide plate 13a, that is, the length from the end of all the curled pieces 21a constituting the entire curled portion 21 provided on the lower end side to the end of all the curled pieces 21c. It is said that it is long.

  Further, a projecting portion 16c formed by cutting and raising the shaft main body portion 16a is provided at the end of the shaft main body portion 16a on the side where the flange portion 16b is provided. As shown in FIG. 13C, the protrusion 16c extends over the length f along the longitudinal direction of the shaft main body 16a, and is a protrusion having a substantially rectangular shape in plan view.

  As shown in FIG. 10 (e) and the like, the protruding portion 16 c has a size that fits almost exactly in the through holes 23 provided in all the curl pieces 21 a and 21 c of the product guide plate 13. More specifically, the length f of the protrusion 16c is slightly smaller than the opening width of the through holes 23 provided in all the curl pieces 21a and 21c of the product guide plate 13, that is, the length of the diagonal line U2. It is.

  Then, as shown in FIG. 10 (e), when the protruding portion 16 c is fitted into the through hole 23, the corner portion of the protruding portion 16 c is substantially in contact with the inner peripheral portion of the through hole 23. Therefore, when the protruding portion 16c is fitted into the through hole 23, the shaft body 16 is in a state where it cannot move in the longitudinal direction or the circumferential direction of the shaft main body portion 16a and is positioned.

  A notch portion 16d is provided at the other end of the shaft body 16, that is, at the end opposite to the flange portion 16b and the protruding portion 16c. The notch 16d is provided at a position opposite to the protrusion 16c in the circumferential direction of the shaft main body 16a, that is, a position shifted by about 180 degrees in the circumferential direction. As shown in FIG. 13B, the notch 16d is a slit-like cut extending in the circumferential direction of the shaft main body 16a, in other words, in a direction intersecting (substantially orthogonal in the present embodiment) to the shaft main body 16a. It is a lack.

  Returning to the description of the assembly structure of the assembly 30, the flapper-constituting body 71 constituting the assembly 30 has the shaft body 16 having all the curl pieces 21 a to 21 c and the curled portions 25 a and 25 b as described above. The product guide plate 13 and the flapper 14 and the coil portion 27 a of the spring 27 that are arranged side by side are inserted.

  Similarly, the structural body 70 constituting the assembly 30 has the shaft body 16 inserted into all the curl pieces 21 a to 21 c provided at the lower end of the product guide plate 13.

  The structure 70 and the structure 71 with the flapper thus configured are arranged on the shaft body 16 formed at the lower end of the structure 71 with the flapper disposed above the structure 70 or the structure 71 with the flapper disposed below. When the half-curl gaps 20x, 20y, and 20z formed by the tips of the half-curl pieces 20a to 20c provided at the upper end and the outer peripheral surface 13c are pressed, a substantially arc shape that is a cross-sectional shape of the half-curl pieces 20a to 20c has its radius. The half-curl pieces 20a to 20c are elastically deformed and fitted in a direction in which the shaft body 16 is enlarged, and the shaft body 16 is disposed inside the half-curl pieces 20a to 20c.

  As described above, the assembly 30 with the flapper is connected to the configuration body 70 or the configuration body 71 with the flapper, and as a result, the assembly 30 is assembled.

  Further, as shown in FIGS. 6 to 8, the shaft body 16 is arranged on the lowermost side in the assembled state to the product storage shelf 10 among the product guide plates 13 constituting the assembly 30 (hereinafter, Although it is also inserted in all the curl pieces 21a to 21c of the product guide plate 13x as required, a structure 70 in which the flapper 14 and the spring 27 are not arranged is used.

  When inserting the shaft body 16, the shaft body 16 is aligned so that the protruding portion 16 c provided in the shaft main body portion 16 a engages with the through hole 23 provided in the entire curled portion 21. That is, when forming the above-described assembly 30a, the protrusion 16c provided in the shaft main body 16a is aligned so as to be engageable with the through hole 23 communicating with the lower shaft communication hole 21c.

  Similarly, when forming the aggregate 30b, the protrusions 16c are aligned so as to be engageable with the through holes 23 communicating with all the curl pieces 21a.

  In other words, in the assembled state of the assembly 30 (30a, 30b), the shaft body 16 has the protruding portion 16c provided on the shaft main body portion 16a facing the outer peripheral surface 13c side of the product guide plate 13, and the notch portion 16d. It is inserted in a posture facing the inner peripheral surface 13b side.

  When the shaft body 16 is inserted, the protruding portion 16c provided on the shaft main body portion 16a engages with the through hole 23 communicated with all the curl pieces 21c. Thereby, even if the shaft body 16 tries to move in the longitudinal direction of the shaft main body portion 16a or tries to rotate in the circumferential direction, the corner portion of the protruding portion 16c hits the peripheral portion of the through hole 23, and the movement and rotation are restricted. It will be in the state.

  Further, as shown in FIGS. 6 to 8, the tip end side (notch portion 16d side) of the shaft body 16 protrudes from the half curl piece 20a and is exposed to the outside. Therefore, the notch 16d provided on the distal end side of the shaft main body 16a is in an open state toward the inner peripheral surface 13b of the product guide plate 13 as shown in FIGS.

It protrudes toward the side. At this time, the jig pins 52 are inserted into the second and third shaft bodies 16 from the lower end side of the assembly 30 as shown in FIG.

  As described above, when the aggregates 30a and 30b are set in a state of being erected substantially perpendicular to the side plate 11, in the state shown in FIG. 21, above the aggregates 30a and 30b, that is, the aggregate 30a. , 30b, the side plate 12 is arranged on the end portion side of the shaft body 16 on the side where the notch portion 16d is provided.

  At this time, similarly to the side plate 11, the side plate 12 also has the shaft insertion portion 17 a of the mounting hole 17 facing the upper side (upper right side in FIG. 21) when assembled as the product storage shelf 10. The direction is adjusted so that the shaft engaging portion 17b faces to the direction (lower left side in FIG. 21).

  Further, in the side plate 12, the mounting holes 17 arranged along the virtual line M1 are opposed to the mounting holes 17 and the mounting holes 17F with stoppers arranged along the virtual line M1 on the side plate 11, and the mounting holes are arranged along the virtual line M2. The direction is adjusted so that 17 faces the mounting holes 17 and the mounting holes 17F with stoppers arranged along the virtual line M2 on the side plate 11 side.

  As shown in FIGS. 21 and 22, the distal end side (notch portion 16 d side) of the shaft body 16 constituting the assembly 30, 30 is inserted into the shaft insertion portion 17 a of each mounting hole 17 provided in the side plate 12. Then, the side plate 12 is placed on one end in the width direction of the aggregates 30a and 30b.

  When the side plate 12 is set as described above, the pair of aggregates 30a and 30b are arranged to face each other between the side plate 11 arranged on the base portion 51 side and the side plate 12 arranged to face the side plate 11. It becomes a state.

When the slider is horizontally slid toward the engaging portion 17b, the aggregates 30 and 30 are slid in the longitudinal direction of the side plates 11 and 12, and the shafts 16 are moved toward the shaft engaging portion 17b. . As a result, the notch 16d provided on the distal end side of each shaft body 16 is engaged with the shaft engaging portion 17b.

  More specifically, when the shaft body 16 moves relative to the side plates 11 and 12 as the jig pin 52 slides as described above, as shown in FIG. The portion 16d side) moves from the shaft insertion portion 17a side to the shaft engaging portion 17b side.

Here, as described above, the shaft body 16 is prevented from rotating by the fitting structure between the projecting portion 16c and all the curl pieces 21a of the product guide plate 13 and the through holes 23 provided in the all curl pieces 21c. The shape-shaped notch 16d faces the inner peripheral surface 13b side of the product guide plate 13, that is, the side that becomes the product guide passage 15 in the assembled state.

  The mounting hole 17 provided on the side plate 12 side has an opening diameter D2 of the shaft insertion portion 17a larger than the outer diameter of the shaft main body portion 16a of the shaft body 16, but the opening width d2 of the shaft engaging portion 17b is It is smaller than the outer diameter of the shaft body 16a. On the other hand, the shaft body 16 is in a posture in which a slit-shaped cutout portion 16 d provided on the distal end side faces the product guide passage 15 side in the assembled state of the product storage shelf 10. Therefore, the imaginary line J1 connecting the terminal portion of the notch 16d and the tangent line J2 of the shaft main body 16a parallel to the tangential line J1 are directions along the longitudinal direction of the shaft engaging portion 17b constituting the mounting hole 17, that is, the axis The body 16 extends in the sliding direction.

  The interval j between the imaginary lines J1 and J2 is set to be equal to or smaller than the opening width d2 of the shaft engaging portion 17b that constitutes the mounting hole 17 provided in the side plate 12.

  As a result, the shaft body 16 is engaged with the side plate 12 and cannot move in the longitudinal direction of the shaft body 16a.

  When the shaft 16 is engaged with the shaft engaging portion 17b as the jig pin 52 slides, as shown in FIG. 23, among the product guide plates 13 constituting the assembly 30, the product storage shelf 10 is provided on the side plates 11 and 12 in order to fix the upper end portion of the product guide plate 13 (corresponding to the product guide plate 13z in FIGS. 6 to 8) located on the upper end side (upper right side in FIG. 23) in the assembly body 10. The fixed shaft 55 is inserted into the shaft insertion hole 18 from above the side plate 12.

  The fixed shaft 55 is inserted through the half curl pieces 20a to 20c constituting the half curl portion 20 of the product guide plate 13z, and is inserted so as to reach the shaft insertion hole 18 provided on the side plate 11 side. Thereby, the aggregates 30 and 30 are in a state where the upper end side is fixed by the fixed shaft 55. Thereby, the assembly of the product storage shelf 10 is completed.

  Next, the operation of the shaft body 16 in the mounting hole 17F with a stopper provided at the lower end of the side plate 11 when the jig pin 52 slides will be described.

  After the flange portion 16b is inserted into the shaft insertion portion 17a, the flange portion 16b moves in the mounting hole 17F with stopper together with the slide of the jig pin 52.

  The tapered portion formed in the vicinity of the distal end of the elastic stopper 17c is formed in a direction in which the distal end is in contact with the side plate 11 at an angle of about 40 ° toward the side plate 11, so that the flange portion 16b is a tapered portion of the elastic stopper 17c. The shaft body 16 moves upward from the assembly jig 50 when it comes into contact with.

  Further, when the shaft body 16 slides in the mounting hole 17F with a stopper, the tip of the elastic stopper 17c is fitted into the inner diameter of the shaft body 16, so that the shaft body 16 is lowered toward the assembling jig 50, and the flange portion 16b is securely attached to the side plate. 11 and the assembly jig 50.

The flange portion 16b exists between the shaft engaging portion 17b and the assembling jig 50, and in the interference between the flange portion 16b and the distal end of the elastic stopper 17c due to further sliding of the shaft body 16, the flange portion 16b The portion 16b moves until it contacts the outside of the side plate 11 (on the assembly jig 50 side), but thereafter, the elastic stopper 17c is elastically deformed in the direction of the assembly jig 50, and the flange portion 16b contacts the elastic stopper 17c. When the elastic stopper 17c disappears, the elastic stopper 17c returns to its original shape, and the distal end of the elastic stopper 17c is positioned on the side plate 11 side with respect to the flange portion 16b.

  Thus, when the shaft body 16 moves in the direction of the shaft insertion portion 17a, the tip of the elastic stopper 17c comes into contact with the shaft main body portion 16a and prevents movement to the shaft insertion portion 17a.

  The product storage shelf 10 assembled as described above is used in a standing state as shown in FIG. In the product storage shelf 10, when a product is inserted or paid out, the product passes from above in the product guide passage 15, and the flapper 14 operates accordingly.

  As described above, the product storage shelf 10 shares the shaft body 16 as the shaft for connecting the product guide plate 13 and the shaft for supporting the flapper 14, and the flapper 14 and the shaft body according to the operation of the flapper 14. 16 performs a predetermined operation, and the stress acting on the product guide plate 13 and the flapper 14 is relaxed.

  Hereinafter, the operation of the product storage shelf 10 will be described focusing on the operations of the flapper 14 and the shaft body 16.

  The product storage shelf 10 puts products enclosed in cans, bottles, plastic bottles, etc. into the product guide passage 15 or dispenses these products from the product guide passage 15 in the product guide passage 15. When the product falls, the product hits the flapper 14 supported in a cantilever manner. Thereby, the flapper 14 inclines the front end side toward the downward direction.

  Here, as shown in FIG. 24 (a), the shaft body 16 that connects the product guide plates 13, 13 arranged in the vertical direction and supports the base end portion of the flapper 14 is shown in FIG. 24 (b). In this manner, the entire curl pieces 21a to 21c and the half curl pieces 20a to 20c are located outside the product guide passage 15 with respect to the regions X1 and X2 side, that is, the vertical line V passing through the bent portion H corresponding to the tip of the flapper contact portion 22. It exists in a position that is off.

  That is, the flapper 14 rotates around the axis G of the shaft body 16 located at a position outside the product guide passage 15 with respect to the vertical line V.

  When the stress in the downward direction as indicated by the arrow F in FIG. 24A is released, the flapper 14 is directed upward from the second arm portion 27c of the spring 27 provided on the back side of the flapper 14. Receive reaction force to. As a result, the flapper 14 rotates about the axis G, and is provided at the lower end of the curved portion 13a of the product guide plate 13 positioned above the shaft body 16 that supports the flapper 14 in due course. It hits against the flapper contact portion 22. Thereby, as shown to Fig.24 (a), the flapper 14 returns to an original attitude | position.

  In the product storage shelf 10 of the present embodiment, the product guide passage 15 is more than the vertical line V through which the shaft 16 supporting the product guide plate 13 and the flapper 14 passes through the lower end of the curved portion 13a of the product guide plate 13. Between the portion (folded portion H) where the flapper 14 and the flapper contact portion 22 provided at the lower end portion of the product guide plate 13 contact, and the axis G of the shaft body 16. The distance, that is, the distance between HG becomes longer.

Therefore, with the operation of the flapper 14, even when the flapper 14 is biased upward by the spring 27 and the flapper 14 abuts against the flapper abutting portion 22, a large amount of stress is applied to the flapper 14 and the flapper abutting portion 22. Does not work. Therefore, the product storage shelf 10 according to the present embodiment is less likely to suffer from problems such as the product guide plate 13 and the flapper 14 being deformed or damaged.

  Further, the product storage shelf 10 of the present embodiment is provided in a standby state, that is, at the lower end portions of the flapper 14 and the product guide plate 13 because the shaft center G is located away from the product guide passage 15. Even in a state where the bent portion H of the flapper contact portion 22 is in contact, an excessively large stress does not act upward on the flapper 14. Therefore, the product storage shelf 10 of the present invention has a stable posture of the flapper 14 during standby.

  In the product storage shelf 10 according to the present embodiment, since the posture of the flapper 14 in the standby state is stable, the product contacts the flapper 14 in substantially the same posture when the product passes through the product guide passage 15. . For this reason, the product storage shelf 10 of the present embodiment is configured such that when the product passes through the product guide passage 15, the product collides with the flapper 14 in an unexpected posture, and the product becomes in an inappropriate posture. Problems such as product jamming in the guide passage 15 are unlikely to occur.

  As described above, the product guide plate 13 employed in the product storage shelf 10 of the present embodiment has the flapper abutting portion 22 formed by bending the lower end side at an acute angle, and the flapper 14 is the flapper holder. It is set as the structure contact | abutted to the ridgeline part of the contact part 22. FIG. Therefore, in the product storage shelf 10 of the present embodiment, even if stress is applied to the lower end portion of the product guide plate 13 as the flapper 14 is operated, the lower end portion of the product guide plate 13 is not easily damaged.

  In the product storage shelf 10 of the present embodiment, a product guide plate 13 and a flapper 14 arranged side by side in the vertical direction are pivotally supported on the side plates 11 and 12 by the same shaft body 16. Therefore, the product storage shelf 10 of the present embodiment does not require a large number of shafts for mounting the product guide plate 13 and the flapper 14 as in the prior art during assembly. Therefore, according to the manufacturing method described in the present embodiment, it is possible to provide the commodity storage shelf 10 that can be manufactured easily and inexpensively.

  In the product storage shelf 10 of the present embodiment, the flapper 14 can be pivotally supported by the same shaft body 16 that pivotally supports the product guide plate 13. Therefore, the product storage shelf 10 according to the present embodiment does not need to separately provide a shaft body for pivotally supporting the flapper 14 at a position outside the product guide passage as in the conventional column. Generation of dead space can be suppressed. Therefore, if the configuration of the product storage shelf 10 of the present embodiment is adopted, the product storage capacity can be improved.

The shaft body 16 is inserted into the shaft insertion portion 17a of the mounting hole 17 of the side plate 11 until the shaft body 16 engages with the shaft engaging portion 17b. Since it is elastically deformed so as to be separated from the shaft insertion portion 17a in a direction substantially perpendicular to the plate surface of the side plate 11, the shaft body 16 is engaged with the shaft engaging portion 17b of the mounting hole 17 of the side plate 11. The force required until the shaft body 16 can be made relatively small, and the variation in the force needed to engage the shaft body 16 with the shaft engaging portion 17b can be made relatively small.

  The elastic stopper 17c having the above-described configuration is substantially perpendicular to the plate surface of the side plate 11 when the shaft body 16 inserted into the shaft insertion portion 17a to the engagement position is slid so as to engage with the shaft engagement portion 17b. When the elastic stopper 17c is pushed away from the shaft insertion portion 17a in the direction, contact with the end portion on the flange portion 16b side of the shaft body 16 is lost, so that the shaft body 16 is elastically returned to a position close to the shaft insertion portion 17a. Is prevented from moving to the shaft insertion portion 17a, so that the force necessary to return the shaft body 16 engaged with the shaft engagement portion 17b to the shaft insertion portion 17a is applied to the shaft engagement portion 17b. The force required to engage can be made larger, and the possibility that the shaft body 16 engaged with the shaft engaging portion 17b will return to the shaft insertion portion 17a without permission due to an impact or the like can be extremely reduced.

  This makes it possible to easily assemble the product storage shelf 10 that is stable in quality, so that the inexpensive product storage shelf 10 and the vending machine 1 can be provided.

The elastic stopper 17c is effective even if it is formed only on one side plate 11 of the pair of side plates 11 and 12, but it is more reliable if it is formed on both side plates 11 and 12. However, when the elastic stopper 17 c is formed on both side plates 11 and 12, the manufacturing cost is higher than when the elastic stopper 17 c is formed on one side plate 11. Therefore, whether to form the elastic stopper 17c on both the pair of side plates 11 and 12 or on one side plate 11 may be selected according to the manufacturing cost effectiveness.

  In the present embodiment, the elastic stopper 17c is fixed in such a manner that the end closer to the shaft engaging portion 17b is a free end and the end far from the shaft engaging portion 17b is connected to the plate surface of the side plate 11. It becomes an end and covers at least a part of the shaft insertion portion 17a.

  With the above configuration, the shaft is inserted in the direction substantially perpendicular to the plate surface of the side plate 11 by being pushed by the end of the shaft body 16 inserted into the shaft insertion portion 17a and slidably moving in the direction of the shaft engagement portion 17b. When the shaft body 16 that is elastically deformed away from the portion 17a and is inserted into the shaft insertion portion 17a to the engagement position is slid so as to be engaged with the shaft engagement portion 17b, contact with the end on the flange portion 16b side The elastic stopper 17c that elastically returns to a position close to the shaft insertion portion 17a and prevents the shaft body 16 from moving to the shaft insertion portion 17a can be easily formed integrally with the side plate 11. it can.

  The elastic stopper 17c has a free end at the end closer to the shaft engaging portion 17b and a fixed end connected to the plate surface of the side plate 11 at the end far from the shaft engaging portion 17b. The distance between the free end and the fixed end of the stopper 17c can be increased to about the outer diameter of the shaft body 16, and the portion pushed by the end of the shaft body 16 on the flange portion 16b side is a portion relatively close to the free end. Thereby, the elastic deformation and elastic return of the elastic stopper 17c can be realized without difficulty.

  The elastic stopper 17c has a free end at the end closer to the shaft engaging portion 17b and a fixed end connected to the plate surface of the side plate 11 at the end far from the shaft engaging portion 17b. The amount of elastic deformation of the elastic stopper 17c can be gradually changed according to the sliding movement of the body 16 from the shaft insertion portion 17a to the shaft engaging portion 17b.

  Further, the force required to return the shaft body 16 engaged with the shaft engaging portion 17b to the shaft insertion portion 17a is reduced by a predetermined amount so that the distance from the fixed end to the free end of the elastic stopper 17c is shortened by a predetermined amount. The force necessary to deform the shaft engagement portion 17b can be set to a force necessary to return the shaft body 16 engaged with the shaft engagement portion 17b to the shaft insertion portion 17a. Since the force required to engage the shaft body 16 with the shaft 17b can be significantly increased, the possibility that the shaft body 16 engaged with the shaft engaging portion 17b will return to the shaft insertion portion 17a without permission due to an impact or the like is extremely high. Can be reduced.

  Further, in the present embodiment, the elastic stopper 17c is a cut and raised piece formed on the side plate 11, and is separated from the plate surface of the side plate 11 in the insertion direction into the mounting hole 17 (the shaft insertion portion 17a) of the shaft body 16. At least a portion of the shaft insertion portion 17a is covered with the inclined position so that the end closer to the shaft engaging portion 17b approaches the plate surface of the side plate 11 as the shaft engaging portion 17b is approached (this embodiment) In this form, the elastic stopper 17c can be formed by the cut and raised pieces formed on the side plate 11 (inclined at an inclination angle of about 40 degrees with respect to the plate surface of the side plate 11).

  In addition, an inclined portion of the end portion of the elastic stopper 17c closer to the shaft engaging portion 17b is made to be a place to be pushed by the end portion on the flange portion 16b side of the shaft body 16, and the shaft engaging portion 17b of the elastic stopper 17c. Of the shaft body 16 from the portion other than the inclined portion of the end portion closer to (the portion of the elastic stopper 17c standing substantially vertical and substantially horizontal to the plate surface of the side plate 11 and the plate surface of the side plate 11). At a position away from the mounting hole 17 (shaft insertion portion 17a) in the insertion direction, the flange portion 16b of the shaft body 16 is at a portion covering at least a part of the shaft insertion portion 17a in parallel to the plate surface of the side plate 11. The elastic deformation and elastic return of the elastic stopper 17c can be easily and smoothly realized while increasing the amount of elastic deformation of the elastic stopper 17c, making it difficult to be pushed by the side end.

  Further, since the elastic stopper 17c is easily elastically deformed in accordance with the sliding movement of the shaft body 16 from the shaft insertion portion 17a to the shaft engagement portion 17b, the shaft body 16 is inserted into the shaft engagement portion 17b of the mounting hole 17 of the side plate 11. The force required to engage the shaft body 16 can be made relatively small, and the place where the elastic stopper 17c is pushed by the end of the shaft body 16 on the flange portion 16b side is limited to a small size. The amount of elastic deformation of the elastic stopper 17c can be gradually changed in accordance with the sliding movement from the portion 17a to the shaft engaging portion 17b.

  In the present embodiment, a flange portion 16b having an enlarged outer diameter at the tip is formed at the end of the shaft body 16 that pushes the elastic stopper 17c. The shaft 16 moves to the shaft insertion portion 17a at a position closer to the plate surface of the side plate 11 on which the elastic stopper 17c is formed than the flange portion 16b (the product guide passage 15 side). This is blocked.

  With the above configuration, after the elastic stopper 17c is elastically restored by the sliding movement of the shaft body 16 to the shaft engaging portion 17b, the shaft body 16 engaged with the shaft engaging portion 17b may return to the shaft insertion portion 17a. The end of the elastic stopper 17c closer to the shaft engaging portion 17b is closer to the plate surface of the side plate 11 on which the elastic stopper 17c is formed than the flange portion 16b (the product guide passage 15 side). The force that the shaft body 16 engaged with the shaft engaging portion 17b tries to return to the shaft inserting portion 17a is prevented from moving to the shaft inserting portion 17a. Even if it works to move the end portion of the elastic stopper 17c closer to the shaft engaging portion 17b to the guide passage 15 side), the end portion of the shaft body 16 on the flange portion 16b side pushes the elastic stopper 17c. It was not work to move the end portion closer to the shaft engaging portion 17b in the direction to the elastic stopper 17c.

  Therefore, the force required to return the shaft body 16 engaged with the shaft engaging portion 17b to the shaft insertion portion 17a is such that the distance from the fixed end to the free end of the elastic stopper 17c is shortened by a predetermined amount. Therefore, the force required to engage the shaft engaging part 17b with the shaft engaging part 17b can be considerably larger than the force required to engage the shaft engaging part 17b. The possibility of returning to the shaft insertion part 17a without permission can be extremely reduced.

  Further, in the present embodiment, the end of the shaft body 16 that presses the elastic stopper 17c on the flange portion 16b side has a hollow cylindrical shape, and the flange portion 16b extends in a flare shape as shown in FIG. 25, and the elastic stopper 17c. The width of the end portion closer to the shaft engaging portion 17b is narrower than the inner diameter of the end portion of the shaft main body portion 16a on which the flange portion 16b is formed, and the elastic stopper 17c is an inclined tip portion of the elastic stopper 17c. And the elastic deformation returns immediately after the elastic deformation is maximized by contact with the inner peripheral surface of the flange portion 16b of the shaft body 16 that slides from the shaft insertion portion 17a to the shaft engagement portion 17b.

  In the above configuration, the end of the shaft body 16 that presses the elastic stopper 17c on the flange portion 16b side has a hollow cylindrical shape, and the flange portion 16b spreads in a flared shape, which is closer to the shaft engaging portion 17b in the elastic stopper 17c. Since the width of the end portion is narrower than the inner diameter of the end portion of the shaft main body portion 16a on which the flange portion 16b is formed, the end portion of the elastic stopper 17c closer to the shaft engaging portion 17b is the elastic stopper 17c. The shaft which slides from the state where it enters the end of the shaft main body 16a on which the flange portion 16b is pressed to the shaft engaging portion 17b from the inclined tip portion of the elastic stopper 17c and the shaft insertion portion 17a. By contact with the inner peripheral surface of the flange portion 16b of the body 16, the end portion of the elastic stopper 17c closer to the shaft engaging portion 17b is gradually pushed out, and the elastic spring 17c is pushed out. Wrapper elastic deformation of 17c becomes largest (restoring force to be elastically restored becomes largest) can easily be configured to elastically restored immediately.

  Therefore, the position of the end portion closer to the shaft engaging portion 17b in the elastic stopper 17c when the elastic stopper 17c is elastically restored is positioned closer to the center in the longitudinal direction of the shaft body 16 with a margin than the flange portion 16b. (The position close to the plate surface of the side plate 11 on which the elastic stopper 17c is formed (product guide passage 15 side)), and the end of the elastic stopper 17c closer to the shaft engaging portion 17b is a flange. The shaft body 16 moves to the shaft insertion portion 17a at a position closer to the center of the shaft body 16 than the portion 16b (position closer to the plate surface of the side plate 11 on which the elastic stopper 17c is formed (product guide passage 15 side)). Can be prevented more reliably.

  Moreover, in this Embodiment, when the edge part by the side of the flange part 16b of the shaft body 16 is inserted in the shaft insertion part 17a, the edge close | similar to the shaft engaging part 17b in the internal peripheral surface of the flange part 16b of the shaft body 16 is shown. The contact (contact) of the end portion of the shaft body 16 on the flange portion 16b side and the inclined tip portion of the elastic stopper 17c so as to contact the end portion of the elastic stopper 17c closer to the shaft engaging portion 17b. Thus, the force that deforms the elastic stopper 17c is prevented from acting so as to increase the distance from the fixed end to the free end of the elastic stopper 17c.

  Further, in the present embodiment, the shaft body 16 is provided at both ends of the product guide plate 13 in the direction of guiding the product, and the elastic stoppers 17c are provided on the top and bottom ends of the product guide plate 13 of the component 70. At least one of them (the lower end side in the present embodiment) is provided to the mounting hole (mounting hole 17F with stopper) of the side plate 11 into which the shaft body 16 is inserted. 13 is provided at both the upper and lower ends in the direction of guiding the product, and particularly when the product guide plate 13 has high rigidity and the product guide plate 13 is difficult to deform in the direction of guiding the product, An elastic stopper for the mounting hole (mounting hole 17F with stopper) of the side plate 11 into which the shaft body 16 at least one of the shaft bodies 16 provided at both ends (the lower end side in the present embodiment) is inserted. If it provided 17c, the effect of preventing the shaft body 16 moves the shaft insertion portion 17a is obtained.

  Further, in the present embodiment, the plurality of product guide plates 13 are connected by the shaft body 16 in the direction in which the products are guided to form the assembly 30, and the elastic stopper 17 c has a plurality of directions in which the products in the assembly 30 are guided. It is provided with respect to the mounting hole (mounting hole 17F with stopper) of the side plate 11 into which the shaft body 16 of at least one of the shaft bodies 16 (the lower end side in the present embodiment) is inserted. When the product guide plate 13 is connected by the shaft body 16 in the direction in which the products are guided to form the assembly 30, particularly when the assembly 30 is difficult to deform in the direction in which the products are guided, With respect to the mounting hole (mounting hole 17F with stopper) of the side plate 11 into which the shaft body 16 in at least one of the plurality of shaft bodies 16 in the direction in which the product is guided (the lower end side in the present embodiment) is inserted. Elastic stopper 17c If provided, the effect of preventing the shaft body 16 moves the shaft insertion portion 17a is obtained.
