【Example】

 An example is shown in FIGS. The parts that are not particularly mentioned are the same as in the conventional example shown in FIGS. In FIG. 1, 100 is a shelf, 102 is an extruder, 104 is a case of the extruder 102, and 106 is a protruding guide. The shelf 100 is fixed to the case 2 shown in FIG. 9 with a hook or the like so that it can be fixed in multiple stages and in a variable height. Reference numerals 108 and 110 denote spur gears, which may be bevel gears or pulleys. The gear 108 is a gear on the tip side of the extruder 102 (the side on which the product is taken out), and the gear 110 is a gear on the rear end side of the extruder 102. The gear 108 is arranged so that the tip thereof slightly protrudes from the case 104. Reference numerals 112 and 114 are grooves formed in the gears 108 and 110, and the wires 116 are passed through the grooves. A belt may be used instead of the wire 116. Reference numeral 118 is a sliding member, and the wire 116 is fixed by using a caulking tool 120, and the sliding member 118 is provided with a push plate 122 and a projecting piece 124. The rotating shaft of the gear 110 at the rear end is allowed to move forward and backward by the cylinder 126, and the gear 128 is pushed by the spring 128 via the cylinder 126 to apply the tension to the wire 116. Reference numeral 130 is a protrusion provided on the bottom surface of the extruder 102, and 132 is a hole provided on the shelf 100. A pair of protrusions 130 are provided in front of and behind the extruder 102, and a large number of holes 130 are provided in the shelf 100 so that the mounting position of the extruder 102 can be changed. That is, the interval between the extruders 102 and 102 can be adjusted according to the width of the product.

FIG. 2 shows a plan view of the extruder 102. The rotation axes of the gears 108 and 110 are perpendicular to the longitudinal direction of the extruder 102, the meshing surface of the gear 108 slightly projects from the case 104, and the meshing surface appears parallel to the end surface of the case 104.

FIG. 3 shows the attachment of the extruder 102 to the shelf 100. As shown in FIG. 4, the hole 132 is formed by connecting the large diameter portion 134 and the small diameter portion 136 that are in close contact with the protrusion 130. When the protrusion 130 provided on the bottom surface of the pusher 102 is inserted into the large diameter portion 134 and the pusher 102 is pushed, the protrusion 130 is closely fitted to the small diameter portion 136 and can be fixed to the shelf 100. When the pusher 102 is used, a force that pushes the gear 108 from a basket 150, which will be described later, acts, and the protrusion 130 is fixed to the small diameter portion 136 by this force. The hole 132 may be any hole as long as the large diameter portion and the small diameter portion communicate with each other. For example, like the hole 142 in FIG. 5, the small diameter portion 146 may be provided in the lateral direction of the rectangular large diameter portion 144. The holes 132 may be through holes or blind holes.

FIG. 6 shows a basket 150 for taking out products. The basket 150 is assumed to be freely movable on the front surface of the case 2 in FIG. 1, but may be movable on the rear surface of the case 2. Reference numeral 152 denotes a movable bottom of the basket 150, which is attached to the basket 150 by a shaft 154, and 156 is a sliding protrusion such as a rotor provided on the movable bottom 152. Reference numeral 158 denotes a shaft for vertically moving the basket 150, and a shaft for horizontally moving is provided in addition to this. These shafts drive a belt by a servo motor (not shown) and move the basket 150 fixed to the belt along a guide. Reference numeral 160 is a dynamic gear, M1 is its motor, 162 is a plate pivotally supported along the rotation axis of the gear 160, and 164 is a driven gear attached to the plate 162. Reference numeral 166 is a spring used to bring the driven gear 164 into close contact with the power gear 160, 168 is a movable plate, 170 is a limit switch, 172 is a control circuit for the motor M1, and 174 is an infrared sensor.

The operation of the embodiment will be described. The shelf 100 is attached to the case 2 with a hook or the like, and the protrusion 100 of the extruder 102 is fitted into the hole 132 to be attached to the shelf 100. At this time, when the protrusion 130 is fitted into the large diameter portion 134 of the hole 132 and the pusher 102 is pushed into the shelf 100, the protrusion 130 comes into close contact with the small diameter portion 136. During use, the driven gear 164 of the basket 150 pushes the gear 108, and the force pushes the protrusion 130 against the small diameter portion 136. Therefore, a large number of extruders 102 can be easily fixed at desired positions.

When the push plate 122 is pushed when the product is stored, the gears 108 and 110 rotate together with the push plate 122, and the push plate 122 can be freely returned to a desired position. This makes it easy to replenish products.

When the product is stored, the position of the shelf 100, the position of the pusher 102, and the price of the product stored at each position are input to a main control circuit (not shown). These data are stored as a set with the product number displayed on the front surface of the case 2. When the consumer throws in a coin and selects a product number, the basket 150 stops at the front of the predetermined pusher 102. This state is shown in FIG. Then, with a signal from the main control circuit (not shown), the power gear 160 rotates clockwise as shown by the arrow in the figure, and as a result, the driven gear 164 rolls on the power gear 160 to the right in the figure. This is because the power gear 160 rotates clockwise and the driven gear 164 is mounted on the plate 162 so as to roll on the power gear 160. When the driven gear 164 moves to the right side of the drawing, the driven gear 164 meshes with the gear 108 of the extruder 102 and drives the gear 108. In the conventional example of FIG. 11, the contact surface of the rotor 8 is in the lateral direction, so the driver 50 must be deeply moved forward and backward by the motor M3. On the other hand, in the embodiment, as shown in FIG. 7, the driven gear 164 may be moved slightly forward.

When the gear 108 is driven, the wire 116 set in the groove 112 moves and the pressing plate 122 advances. When a product is dropped into the basket 150 by the push plate 122, the infrared sensor 174 or the like detects this, and the power gear 160 is rotated counterclockwise by the signal of the control circuit 172. As a result, the driven gear 16 is rotated as shown in FIG. Roll to the left and away from gear 108.

When the product is driven in the empty row (in the sold-out row), the sliding member 118 is advanced to the tip of the extruder 102, and the projecting piece 124 pushes the plate 168. The plate 168 touches the limit switch 170. Then, in response to a signal from the control circuit 172, the power gear 160 rotates counterclockwise, and the driven gear 164 separates from the gear 108 as in the case described above. Instead of providing the limit switch 170, the driven gear 164 may be pulled back by the spring 176 shown by the chain line in FIG.

When a product falls on the basket 150, the basket 150 moves to a position facing the product outlet 180. This state is shown in FIG. Reference numeral 182 is a lid of the take-out port 180, 184 is a product accommodation space of the take-out port 180, and 186 is a guide for contacting the sliding protrusion 156. When the basket 150 descends here, the sliding protrusion 156 contacts the guide 186. Since the sliding protrusion 156 can only move along the guide 186, the movable bottom 152 opens as shown by the chain line in the figure, and the product falls into the take-out port 180. When the product falls and is detected by an infrared sensor (not shown) or the like, the basket 150 rises and the movable bottom 152 separates from the guide 186 and closes by its own weight. Therefore, even if the user puts his / her hand through the lid 182, it is blocked by the movable bottom 152 and the hand cannot be put in the basket 150. Further, when the product is conveyed from the shelf 100, the movable bottom 152 is closed and the product does not drop to the product outlet 180.

Although the basket 150 is used to take out the product here, the product may be taken out by a belt conveyor provided on the shelf 100 along the front surface of the pusher 102. In that case, for example, a motor may be provided for each pusher to drive the gears 108 and 110.
