As shown in FIGS. 1, 4, and 5, the opening / closing device 1 includes a first member 11, a second member 12, a coupling mechanism 13, and a drive mechanism 14 (see FIGS. 6A and 6B). I have.

  The first member 11 is formed in a plate shape, and moves in the X-axis direction (first direction, left-right direction) by power from the drive mechanism 14. The first member 11 includes a rectangular plate-shaped base portion 111 and a connection portion 112 to which a shaft 133 described later is connected.

  The second member 12 is configured to be fitted with the bottom plate 94 of the shopping basket 9 placed in the placement space S1. The second member 12 includes a base portion 15, a plurality (two in the illustrated example) of distal end portions 16, a connection portion 17, and a detection member 18. The connection portion 17 has a through hole 171. The detection member 18 has, for example, a plate shape, and the second member 12 is located at the proximal end so that the distal end is positioned closer to the first member 11 than the left edge of the second member 12. Is attached.

  The base 15 includes a rectangular plate-shaped main piece 151 and a plurality (two in the illustrated example) of rectangular plate-shaped protrusions 152. The plurality of projecting portions 152 project from both ends of the main piece 151 in the Y-axis direction in a negative direction in the X-axis direction. The main piece 151 and the plurality of protrusions 152 are integrally formed.

  The plurality of tip portions 16 protrude in the negative direction in the X-axis direction from both ends of the base portion 15 in the Y-axis direction. The plurality of tip portions 16 are attached to the plurality of protrusions 152. Each distal end portion 16 has a rectangular base portion 161, a claw portion 162, and a pressing portion 163. In the present embodiment, for example, by processing a rectangular parallelepiped metal member, the base portion 161, the claw portion 162, and the pressing portion 163 are integrally formed. Thereby, intensity | strength can be raised rather than the case where the base part 161, the nail | claw part 162, and the press part 163 are separate bodies.

  The base 161 is inclined so that the length in the X-axis direction becomes shorter as it approaches the lower surface from the upper surface in the Z-axis direction.

  The claw portion 162 protrudes along the Z-axis direction from the tip in the X-axis direction of the upper surface (first surface) of the base portion 161. The claw portion 162 is hooked on the bottom plate 94 when the bottom plate 94 is opened (see FIG. 5).

  The pressing portion 163 protrudes along the Z-axis direction from a portion between the base end and the distal end connected to the base portion 15 in the X-axis direction on the upper surface of the base portion 161. The pusher 163 pushes the bottom plate 94 when closing the bottom plate 94. The pressing portion 163 has a larger contact area with the bottom plate 94 than the claw portion 162.

  The connection mechanism 13 connects the first member 11 and the second member 12. The connection mechanism 13 includes a connection member 131 and an elastic member (elastic body) 132.

  The connecting member 131 includes a shaft 133 and a flange part 134. The shaft 133 is fixed to the first member 11 at the first end of both ends in the axial direction, and passes through the through-hole 171 of the second member 12 at the second end of both ends. . The flange 134 is larger than the through hole 171 and is fixed to the second end of the shaft 133.

  The elastic member 132 is provided around the shaft 133 and between the connection portion 112 of the first member 11 and the connection portion 17 of the second member 12, and is elastically displaced in the axial direction of the shaft 133. The elastic member 132 is a spring, for example. The elastic force is adjusted by the spring constant of the spring.

  The drive mechanism 14 is configured to move the first member 11. The drive mechanism 14 includes a motor, a power transmission mechanism 142 (see FIGS. 6A and 6B), and a plurality (two in the illustrated example) of linear guides 143. The power transmission mechanism 142 transmits the power of the motor to the first member 11. The plurality of linear guides 143 guide both the first member 11 and the second member 12 along the X-axis direction. Each linear guide 143 includes a rail 144 and a plurality (two in the illustrated example) of blocks 145 (see FIG. 3). The rail 144 is provided along the X-axis direction. The plurality of blocks 145 are attached to the first member 11 and the second member 12 and move on the rail 144.

  In the opening / closing device 1 as described above, the first member 11 pulls and moves the second member 12 fitted to the bottom plate 94 by the power from the drive mechanism 14 when the bottom plate 94 is opened.

  First, before the shopping basket 9 is placed in the placement space S1, as shown in FIG. 6A, the first member 11 and the second member 12 have the claw portion 162 of the second member 12 placed in the placement space S1. Move to the right so that it is located at Then, when the shopping basket 9 is placed in the placement space S1, the claw portion 162 is caught on the bottom plate 94 of the shopping basket 9 (see FIG. 5). Thereafter, when the first member 11 is moved to the left side by the power of the motor of the drive mechanism 14, the collar portion 134 of the coupling mechanism 13 comes into contact with the periphery of the through hole 171 in the connection portion 17 of the second member 12. When pulled by the first member 11, the second member 12 also moves to the left. At this time, as shown in FIG. 6B, since the claw portion 162 of the second member 12 is hooked on the bottom plate 94 of the shopping basket 9, the bottom plate 94 also moves to the left side together with the second member 12. Thereby, the baseplate 94 can be removed from the body 93 and the lower surface of the shopping basket 9 can be opened.

  Here, since the base portion 161 and the claw portion 162 are integrally formed, even when the fitting force between the bottom plate 94 and the body 93 is large, the claw portion 162 is hooked on the bottom plate 94 and opened and closed. The device 1 can pull out the bottom plate 94.

  Next, when the first member 11 closes the bottom plate 94 to the body 93, the bottom plate 94 is moved using the elastic force of the elastic member 132 of the coupling mechanism 13 by the power from the drive mechanism 14.

  First, in the state of FIG. 6B, when the first member 11 is moved in the negative direction in the X-axis direction by the power of the motor of the drive mechanism 14, the second member 12 is also moved to the right side by the elastic force of the elastic member 132. Moving. At this time, when each pressing portion 163 of the second member 12 pushes the bottom plate 94 to the right side, the bottom plate 94 also moves to the right side together with the second member 12. When the bottom plate 94 is pushed by the pushing portion 163 of the second member 12 and moves to the right side, the bottom plate 94 is inserted into the groove 965 through the opening 973 of the body 93 and is finally fitted into the body 93. . Thereby, the baseplate 94 can be attached to the body 93 and the lower surface of the shopping basket 9 can be closed.

  Here, in the middle of moving the bottom plate 94 to the right side, if a force that prevents the bottom plate 94 from moving to the right side is applied to the bottom plate 94 more than necessary, the second member 12 is prevented from moving to the right side. Nevertheless, the first member 11 moves to the right as it is. Since the connecting portion 17 of the second member 12 and the connecting member 131 of the connecting mechanism 13 are not fixed, the first member 11 approaches the second member 12, and the first member 11 and the second member 12 The distance L1 between the member 12 is shortened. Since the elastic member 132 is provided around the shaft 133, the force from the first member 11 is transmitted to the second member 12 while being loosened by the elastic member 132.

  At this time, if a foreign substance exists in the lower opening 932 of the body 93, the foreign substance comes into contact with the bottom plate 94, thereby preventing the movement of the bottom plate 94. In this case, the force on the second member 12 is smaller than the force from the first member 11 by the elastic member 132. Therefore, even when the second member 12 collides with a foreign object, the impact from the second member 12 to the foreign object can be reduced.

  By the way, the opening / closing device 1 further includes a plurality (two in the illustrated example) of optical sensors 19 as sensors for detecting that the distance between the first member 11 and the second member 12 is a predetermined distance or less. ing.

  Each of the plurality of optical sensors 19 includes a light emitting unit that emits light and a light receiving unit that receives light from the light emitting unit, and is provided on the first member 11. Each optical sensor 19 detects that the distance L1 between the first member 11 and the second member 12 is equal to or less than a predetermined distance when the detection member 18 is inserted between the light emitting unit and the light receiving unit. To do.

  The distal end portion of the detection member 18 is inserted between the light emitting portion and the light receiving portion of each optical sensor 19 when the distance L1 between the first member 11 and the second member 12 becomes a predetermined distance or less. . That is, the length of the detection member 18 is such that when the distance L1 between the first member 11 and the second member 12 is equal to or less than a predetermined distance, the tip portion is between the light emitting portion and the light receiving portion of each optical sensor 19. Is such a length that is inserted.

  When the opening / closing device 1 moves the bottom plate 94 to the right along the X-axis direction, if foreign matter is present in the lower opening 932 of the body 93, the foreign matter comes into contact with the bottom plate 94 and prevents the bottom plate 94 from moving. It will be. In this case, since the movement of the second member 12 pushing the bottom plate 94 becomes small, the first member 11 approaches the second member 12, and between the first member 11 and the second member 12. The distance L1 becomes shorter. When the distance L1 is equal to or less than the predetermined distance, the tip end portion of the detection member 18 is inserted between the light emitting portion and the light receiving portion of each optical sensor 19. At this time, each optical sensor 19 detects that the distance L1 is not more than a predetermined distance.

  Thereafter, each optical sensor 19 transmits the detection result to the management device 7. As will be described later, when receiving the detection result from each optical sensor 19, the management device 7 controls the motor so as to stop the rotation. The motor stops according to the control by the management device 7. As a result, the first member 11 stops moving.

(2.3) Car Moving Device The car moving device 2 is configured to move the shopping basket 9 from the placement space S1 to the collecting device 4. The car moving device 2 includes a pushing mechanism 21 and a car driving mechanism 22 as shown in FIGS.

  The car drive mechanism 22 is configured to move the push mechanism 21. The car drive mechanism 22 includes a motor 221, a car power transmission mechanism 222, and a linear guide 223. The car power transmission mechanism 222 transmits the power of the motor 221 to the push mechanism 21. The car power transmission mechanism 222 has a pulley 227 and a belt 228. The pulley 227 is rotated by the power of the motor 221. The belt 228 moves as the pulley 227 rotates. The linear guide 223 guides the push mechanism 21 along the Y-axis direction. The linear guide 223 includes a rail 224 and a block 225. The rail 224 is attached to the support base 226 along the Y-axis direction. The block 225 is attached to the push mechanism 21 and moves on the rail 224.

  The push mechanism 21 is a mechanism for pushing the shopping basket 9 from the placement space S1 to the collection device 4. As shown in FIG. 9, the push mechanism 21 has a base portion 23 and a contact portion 24. The base 23 is attached to the block 225 and the belt 228 of the car drive mechanism 22. The contact part 24 is a member that contacts the shopping basket 9 when the shopping basket 9 is moved. When the base 23 receives power from the car drive mechanism 22, the push mechanism 21 moves along with the base 23 along the Y-axis direction. Thereby, when the shopping basket 9 is moved, the contact portion 24 contacts the body 93 of the shopping basket 9 and pushes the shopping basket 9, thereby moving the shopping basket 9 from the placement space S <b> 1 to the collection device 4. it can.

  By the way, after moving the shopping basket 9 to the collection | recovery apparatus 4, before returning the pushing mechanism 21 to an original position, the case where the next shopping basket is already put into mounting space S1 is considered. In this case, if the contact portion 24 remains in the open position, the contact portion 24 may come into contact with the next shopping basket when the push mechanism 21 is returned to the original position.

  Therefore, the push mechanism 21 enables the contact portion 24 to be displaced between the open position and the closed position. The push mechanism 21 further includes a shaft 25, a pin 26, and an elastic member 27.

  The shaft 25 is provided so that the contact portion 24 can rotate with respect to the base portion 23. The shaft 25 passes through the through hole of the base portion 23 and the through hole of the contact portion 24. Thereby, the contact portion 24 can rotate between the open position and the closed position around the shaft 25.

  The pin 26 is fitted with the contact portion 24 to suppress the rotation of the contact portion 24. The pin 26 penetrates the through-hole formed in the base 23 at the lower end which is the first end in the axial direction. Further, the lower end portion of the pin 26 is inserted into a recess formed in the contact portion 24 when the contact portion 24 is in the open position.
