Then, the lower link pin 62 moves downward along the elongated hole 11B12 (see FIG. 4) formed in the opening flange 11B of the substrate 1 and the elongated hole 512 (see FIG. 5) formed in the bearing member 50 in the bearing portion 4. ing. In the sales standby state, the first stopper member 2 is in the protruding position due to the elastic urging force of the torsion coil spring 20a (see FIG. 2). Further, the first stopper member 2 receives the load of the product G because the product G1 for sale is in contact with the holding surface thereof. Further, in the sales standby state, the rotation stopper 7 is in the protruding position due to the elastic urging force of the torsion coil spring (not shown). Further, the rotation stopper 7 applies the load of the product G on the first stopper member 2 by engaging the lock pin 71 with the small diameter groove portion 25a (see FIG. 8) of the deformed groove 25 in the first stopper member 2. is recieving. Further, the rotation stopper 7 is maintained in a protruding position by engaging the lower link pin 62 with the lock groove 7c (see FIG. 9). As a result, the rotation stopper 7 locks the first stopper member 2 to the protruding position and prevents the first stopper member 2 from moving to the retracted position. Further, in the sales standby state, the second stopper member 3 returns to the retracted position by the elastic urging force of the torsion coil spring (not shown), and the upper link pin 61 enters the concave sliding groove 33a formed in the stopper wall 33. doing. In this case, the extending portions 32A and 32A of the second stopper member 3 pass through the extending portions 11a and 11a (see FIGS. 3 and 4) formed in the upper region of the opening 11 of the substrate 1 and are retracted. Has returned to. Further, the closing plate 15 hangs down along the substrate 1.

When the solenoid 5 is energized by a sales command from the sales standby state shown in FIG. 12, the solenoid 5 sucks the plunger 5A against the elastic urging force of the return spring 66 to raise the link member 60. Then, the lower link pin 62 supported by the link member 60 rises, and the engagement of the rotation stopper 7 with the lock groove 7c is released. By this unlocking, the rotation stopper 7 rotates toward the retracted position around the rotation shaft 70 due to the product load, and the lock pin 71 also disengages from the small diameter groove portion 25a of the deformed groove 25 and the first stopper member. The lock of 2 is released, and the first stopper member 2 rotates toward the retracted position due to the product load.

At the same time, the second stopper member 3 protrudes from the retracted position toward the protruding position by the upper link pin 61 supported by the rising link member 60. That is, when the link member 60 rises from the sales standby state, the upper link pin 61 that has entered the sliding groove 33a of the second stopper member 3 rises while sliding on the groove wall of the sliding groove 33a. As a result, the second stopper member 3 moves around the rotation shaft 30 toward the protruding position against the elastic urging force of the torsion coil spring. When the link member 60 rises to the upper limit position, the upper link pin 61 engages with the stopper surface 33b of the second stopper member 3 to lock the second stopper member 3 to the protruding position. In the process of moving the second stopper member 3 from the retracted position to the protruding position, the tip (holding portion 32) of the second stopper member 3 is on the back surface of the closing plate 15 (the side opposite to the surface exposed in the product storage passage 183). The closing plate 15 is pushed out into the product storage passage 183 in contact with the product storage passage 183. That is, the closing plate 15 is pushed out into the product passage 183 in conjunction with the movement of the second stopper member 3 from the retracted position to the protruding position. The holding portion 32 of the second stopper member 3 that has reached the protruding position locks the next-sale product G2 together with the closing plate 15 that closes the gap between the substrate 1 and the holding portion 32, and is between the outlet adjusting plate 290. Holds the next sale product G2. As a result, only the product G1 sold at the lowest position slips through the first stopper member 2 and is carried out (see FIG. 13).

When the product G1 for sale is carried out and the first stopper member 2 no longer receives the product load, the first stopper member 2 returns to the protruding position (sales standby position) by the urging force of the torsion coil spring 20a (see FIG. 14). .. At the same time, the rotation stopper 7 also returns to the protruding position by the elastic urging force of the torsion coil spring. In this case, the lock pin 71 provided at the tip of the rotation stopper 7 slides on the wall surface of the large diameter groove portion 25b of the deformed groove 25 in the first stopper member 2 to reach the small diameter groove portion 25a. As a result, the first stopper member 2 is locked at the sales standby position.

Then, when the energization of the solenoid 5 is lost, the link member 60 is lowered by the urging force of the return spring 66, so that the lock of the second stopper member 3 by the upper link pin 61 is released, and the second stopper member 3 is twisted. It returns to the standby position by the urging force of the coil spring. Further, when the link member 60 is lowered to the lower limit position, the lower link pin 62 engages with the lock groove 7c of the rotation stopper 7 to lock the first stopper member 2 to the sales standby position (see FIG. 12).

As shown in FIG. 15, the upper link pin 61 and the lower link pin 62 of the link mechanism 6 in the product unloading device 10 described above are made of a cylindrical shaft-shaped member with a header. Since the configurations of the upper link pin 61 and the lower link pin 62 are the same, FIG. 15 shows the upper link pin 61, and the reference numerals of the corresponding lower link pins 62 are shown in parentheses.

The upper link pin 61 (62) is in the form of a flask container (chemical laboratory instrument) in which the long lower part of the neck bulges in the out-diameter direction and the bottom bulges in the out-diameter direction as a whole. A body portion 61a (62a) made of a hollow cylindrical body corresponding to the long neck of the flask container, a ring-shaped header 61b (62b) connected to the body portion 61a (62a) and bulging outward in diameter, and the above. An opening 610 (620) having a diameter d smaller than the diameter D of the header 61b (62b) is provided on the crown side of the header 61b (62b), and a tapered portion 61c (62c) is provided on the tip end side of the body portion 61a (62a). ) Is provided. Then, the upper link pin 61 (62) has the opening edge of the opening 610 (620) inside the ring-shaped header 61b (62b) as shown by “Z” in FIG. 15 (b). It is formed as a cylindrical shaft-shaped member with a recessed header.

The upper link pin 61 (62) is formed by pressing a rectangular steel plate as a material through the manufacturing steps (S1) to (S5) of FIG. That is, first, as shown in the step (S1), a rectangular flat plate is cut into a strip-shaped part CP in which one end side is spread in an inverted trapezoidal shape. In this case, both ends CP1 and CP1 on the long side of the strip-shaped part that becomes the abutting surface when curling into a cylindrical shape are cut so as to be inclined at an acute angle from the edge that becomes the outer wall to the edge that becomes the inner wall (inner). Cut so that the outer circumference is longer than the circumference), and when both ends CP1 and CP1 are butted, as in the case where both ends CP1 and CP1 on the long side of the strip-shaped part CP are cut vertically, the inner wall Are in contact with each other first to prevent a gap (V-shaped groove) from being formed between the outer walls. Further, one end CP3 on the short side of the strip-shaped component CP is cut so as to be inclined at an obtuse angle from the edge serving as the outer wall to the edge serving as the inner wall in order to form the tapered portion 61c (62c). Is what you are doing.

In the next step (S2), both ends CP1 and CP1 on the long side of the strip-shaped component CP and the other end CP2 on the short side are slightly curved to one side (lower side with respect to the paper surface in FIG. 16). Bend to do so. Both ends CP1 and CP1 on the long side of the strip-shaped part CP are curved so that both ends CP1 and CP1 on the long side of the strip-shaped part CP that become a seam when curled into a cylindrical shape are outward in diameter. This is to prevent protrusion and make the seam a smooth arc.

Next, curling is gradually performed in the order of steps (S3) and (S4). In the step (S3), the entire long side of the component CP is curled, and the end CP2 on the short side is bent so as to curve to one side. In this way, the end CP2 on the short side side of the strip-shaped component CP is curved so that the header 61b (62b) of the final product is formed as a hollow ring shape and the top of the header 61b (62b) is formed. This is to open an opening 610 (620) having a diameter d smaller than the diameter D of the header 61b (62b). In the step (S4), the cross section of the component CP has an elliptical shape, and both ends CP1 and CP1 on the long side are curled in a narrowing manner. In the steps (S2) to (S4), a convex lower mold and a concave upper mold corresponding to the curl shape in each step are used, and these lower molds and upper molds are used. Press the part CP.

In the step (S5), the component CP is press-processed by the lower mold and the upper mold forming a semicircle according to the final form. Finally, as shown in FIG. 15B, the edge of the opening 610 (620) at the crown of the header 61b (62b) is recessed inside the header 61b (62b). As a result, the long body portion 61a (62a) made of a hollow cylindrical body, in which the long lower part of the neck bulges in the extradiameter direction and the bottom bulging in the extradiameter direction forms the form of a flask container with an opening. A ring-shaped header 61b (62b) bulging outward in diameter and an opening 610 (620) having a diameter d smaller than the diameter D of the header 61b (62b) are provided on the crown side of the header 61b (62b). Therefore, a cylindrical shaft-shaped member with a header is obtained in which the opening edge of the opening 610 (620) is recessed inside the ring-shaped header 61b (62b). In this case, since the opening edge of the opening 610 (620) is one end on the short side side of the rectangular steel plate as the material, the opening edge has sharp corners, but the opening By recessing the opening edge of the portion 610 (620) inside the ring-shaped header 61b (62b), the corner of the opening edge of the opening 610 (620) is outside the header 61b (62b). It does not protrude.

By using the upper link pin 61 and the lower link pin 62 of the link mechanism 6 composed of a cylindrical shaft-shaped member with a header having such a configuration, the opening edge of the opening 610 (620) on the distal end side of the header 61b (62b) can be used. The sharp corners are located inside the tip (top of the head) of the header 61b (62b), and the corners of the edge do not protrude outside the header 61b (62b). Therefore, even if the wiring guide 9, which is a mating member facing the tip (top) of the header 61b (62b), comes into contact with the tip (top) of the header 61b (62b), it may be scraped by the corner of the opening edge. The upper link pin 61 and the lower link pin 62 slide smoothly even when the header 61b (62b) of the upper link pin 61 and the lower link pin 62 and the wiring guide 9 which is a mating member are in contact with each other. It can be moved.

In the above-described embodiment, it has been described that the rotation shaft 70 of the upper link pin 61, the lower link pin 62, and the rotation stopper 7 is a cylindrical shaft-shaped member with a header, but the first stopper member 2, The rotating shafts 20 and 30 of the second stopper member 3 can be made into a cylindrical shaft-shaped member with a header.

FIG. 17 shows a modified example of the cylindrical shaft-shaped member with a header used in the product unloading device of the vending machine according to the embodiment of the present invention, and FIG. 17A is a perspective view of the cylindrical shaft-shaped member with a header. , (B) are CC sectional views of (a). In this modification, the upper link pin 61A and the lower link pin 62A of the link mechanism 6 are shown, and those having the same function as those shown in FIG. 15 are designated by the same reference numerals.

The difference between the upper link pin 61A and the lower link pin 62A as the cylindrical shaft-shaped member with a header shown in FIG. 17 from the upper link pin 61 and the lower link pin 62 shown in FIG. 15 is that the strip-shaped part It is the cross-sectional shape of the abutment portion (seam) at both ends on the long side. That is, the upper link pin 61 and the lower link pin 62 shown in FIG. 15 are formed by abutting the outer walls at both ends on the long side of the strip-shaped component so that the seams form a smooth arc. On the other hand, the upper link pin 61A and the lower link pin 62A shown in FIG. 17 form a groove 61aa (62aa) having a substantially U-shaped cross section at the seam, and a circle on the outer peripheral surface of the cylindrical body from the groove 61aa (62aa). A round portion R is formed in a portion facing the surface. The upper link pin 61A and the lower link pin 62A are also manufactured by the manufacturing process shown in FIG. In this case, in the step (S1) shown in FIG. 16, both ends on the long side of the strip-shaped part were plastically deformed so as to be slightly curved to one side, whereas in the modified example of FIG. 17, the seam was formed. Formes a U-shaped groove 61aa (62aa) having a U-shaped cross section recessed inward in a manner in which the cylinder is positioned inside the circle (dotted chain line CG) on the outer peripheral surface of the cylinder, and the groove 61aa (62aa) forms the cylindrical body. It is bent so as to form a round portion R at a portion of the outer peripheral surface facing the circular CG. According to the upper link pin 61A and the lower link pin 62A, the corners of the steel plate edge are not exposed on the circumference of the outer peripheral surface of the cylindrical body because the steel plate edge as the seam is recessed inward. The upper link pin 61A and the lower link pin 62A can be smoothly slid along the elongated holes 511 and 512 provided in the bearing pieces 51 and 51 of the bearing member 50 and the elongated holes 11B11 and 11B12 of the flange 11B of the substrate 1. It can be done.

As described above, the strip-shaped steel plate is curled so that both ends on the long side of the strip-shaped steel plate are butted against each other, and headers 61b and 62b that bulge out of the diameter are provided at one end of the strip-shaped steel plate on the short side. The cylindrical shaft-shaped member with a header (upper link pin 61, lower link pin 62), and the cylindrical shaft-shaped member with a header (upper link pin 61, lower link pin 62) has a long neck in the outward direction. A long body (61a, 62a) and a ring-shaped header (61b, 62b) that bulges out of the diameter and forms a flask container with an open bottom. And an opening (610, 620) having a diameter (d) smaller than the diameter (D) of the header (61b, 62b) is provided on the crown side of the header (61b, 62b), and the opening (610, 620, By recessing the open edge of 620) inside the ring-shaped headers (61b, 62b), the headers (61b, 62b) in the cylindrical shaft-shaped member (upper link pin 61, lower link pin 62) The corner of the edge at one end on the short side of the steel plate, which is the material, is located inside the ring-shaped header (61b, 62b), which is the opening edge at the opening (610, 620). Since the corners of the opening (610, 620) opening edge of 61b, 62b) do not protrude to the outside of the header (61b, 62b), the partner that contacts the tip (top of the head) of the header (61b, 62b). The side member (wiring guide 9) is not likely to be scraped by the corner of the opening edge at the opening (610, 620) of the header (61b, 62b), and the cylindrical shaft member (upper link pin 61, The cylindrical shaft-shaped member (upper link pin 61, lower link pin 62) slides smoothly even when the header (61b, 62b) of the lower link pin 62) and the mating member (wiring guide 9) are in contact with each other. It has the effect of being able to.

Further, in addition to the rotation shaft 70 of the rotation stopper 7, the rotation shafts 20 and 30 of the first stopper member 2 and the second stopper member 3 are formed into cylindrical shaft-shaped members with headers, so that the product unloading device 10 can be used.
