  By the way, in the automatic safe deposit system as disclosed in Patent Document 1, the storage box may be transported to the handling table via the lifting device, or may be transported from the handling table to the storage space. In this case, in order to detect the weight of the storage box with the storage box placed on the lifting device, it is necessary to incorporate a weight detector into the lifting device itself.

  For example, the weight detector is incorporated in the lifting device. For example, the mounting table is supported on a movable body that is driven to move up and down via a spring or the like, and a spring is interposed between the movable body and the mounting table. Conceived configurations are possible. In this case, when the storage box is mounted on the mounting table, the mounting table approaches the movable body against the spring biasing force, so the weight of the storage box can be increased by detecting the distance between the movable body and the mounting table. Can be detected.

  However, in the above configuration, if a relative twist occurs between the mounting table and the movable body, the mounting table is difficult to move up and down by an amount corresponding to the weight of the storage box, and the weight detection accuracy deteriorates. There is a fear. In particular, when a configuration in which the movable body is moved up and down by a ball spline mechanism as the lift drive mechanism is used, the above-described problem is likely to occur because the movable body rotates with the lift movement.

  Therefore, an object of the present invention is to make it possible to more accurately detect the weight of the safe box when the safe box is moved up and down.

The screw part 154 is screwed with the elevating drive shaft part 142, and by rotating the elevating drive shaft part 142 in a state in which the elevating movable part 150 is not rotated around the axis of the elevating drive shaft part 142, The screw part 154 moves up and down according to the spiral groove of the lifting drive shaft part 142. A configuration that prevents the elevating movable unit 150 from rotating about the axis of the elevating drive shaft 142 will be described later.

  But the raising / lowering movable part 150 itself may be the structure which raises / lowers by drive of what is called an air cylinder, a hydraulic cylinder, what is called a linear motor other than the said structure.

  The elevating mounting table 160 includes a mounting side movable unit 170 and a pair of mounting frame units 180.

  The placement-side movable unit 170 is disposed above the lift movable unit 150 with a coil spring 174 as an elastic member interposed therebetween, and moves up and down together with the lift movable unit 150.

  More specifically, the placement-side movable portion 170 is formed in a rectangular plate shape, and a hole 171 into which the elevating drive shaft portion 142 can be inserted is formed in an intermediate portion thereof (FIGS. 7 and 8). (See FIG. 9). The placement side movable portion 170 is disposed on the lift movable portion 150 in a state where the lift drive shaft portion 142 is inserted into the hole 171. In addition, a coil spring 174 is externally fitted to the elevating drive shaft 142 between the elevating movable unit 150 and the placement side movable unit 170. Thereby, the placement side movable part 170 is supported above the elevating movable part 150 by the elastic support force of the coil spring 174, and the coil spring 174 is elastically deformed according to the vertical force applied to the placement side movable part 170. Thus, the placement side movable portion 170 is displaced with respect to the liftable movable portion 150.

  In addition, the longitudinal direction of the placement-side movable unit 170 and the longitudinal direction of the lift-and-fall movable unit 150 coincide with each other, and holes 171 h are formed at both ends of the placement-side movable unit 170 and both end portions of the lift-and-fall movable unit 150. A hole 151h is formed in the surface (see FIGS. 7 and 8). The pin member 176 is provided so as to vertically penetrate the hole 171h and the hole 151h, and the upper and lower heads of the pin member 176 are locked to the hole 171h or the hole 151h in a retaining manner. In addition, the distance between the placement-side movable unit 170 and the liftable movable unit 150 is restricted so as not to be larger than the length of the pin member 176.

  The pair of mounting frame portions 180 has a portion extending in the horizontal direction from the mounting-side movable portion 170, and is configured so that the safe box 90 can be mounted on the horizontally extending portion.

  More specifically, the mounting frame portion 180 has a shape in which a vertical frame portion 182 extending along the vertical direction and a horizontal frame portion 186 extending along the horizontal direction are connected in a substantially L shape. ing.

  The pair of vertical frame portions 182 are disposed at positions sandwiching the elevating drive shaft portion 142, and both end portions of the placement side movable portion 170 are connected and fixed to the inner surfaces of the pair of vertical frame portions 182 by screws or the like. Yes. Accordingly, the pair of mounting frame portions 180 are supported in a parallel posture with a predetermined interval, and are moved up and down together with the mounting side movable portion 170.

  In addition, a pair of guide rods 184 are erected on both outer surface sides of the pair of vertical frame portions 182, and the guide rod 184 is movable to a guided body 185 attached and fixed to the outer surfaces of the pair of vertical frame portions 182. It is inserted. Since the pair of guided bodies 185 are supported so as to be movable along the guide rod 184, the present lifting platform 160 is supported so as to be movable up and down.

  Further, the pair of horizontal frame portions 186 extends in a cantilevered manner from the upper ends of the pair of vertical frame portions 182 toward the center side of the base plate 132. On the upper edge of the pair of horizontal frame portions 186, a mounting plate portion 180p projecting in a flange shape toward the inside is formed, and the safe box 90 can be mounted on the pair of mounting plate portions 180p. Yes.

  A relay unit 162 described below is disposed between the pair of horizontal frame units 186.

  The relay part 162 is supported by the support pillar part 169 at a position adjacent to the booth side horizontal movement part 32, and is configured to be able to exchange the safe box 90 with the booth side horizontal movement part 32. (See FIGS. 5 and 6). Here, the relay portion 162 is rotatably supported by each of the pair of pulley support frames 163 so that the plurality of feed pulleys 164 are arranged in a straight line at intervals, and the plurality of feed pulleys The feeding belt 165 is attached so as to be wound around the entire 164. The rotational driving force of the feed motor 166 is transmitted to the feed pulley 164 on one end side via the transmission belt 167. Then, the feeding belt 165 is rotationally driven in both forward and reverse directions by the rotational driving of the feeding motor 166, whereby the safe box 90 fed from the booth side horizontal movement unit 32 is taken into the relay unit 162, and The safe box 90 on the relay unit 162 is sent toward the booth side horizontal moving unit 32.

  The pair of horizontal frame portions 186 move up and down relatively with respect to the relay portion 162. That is, the elevating mounting table 160 has a lowered position (see FIGS. 5 and 7, that is, the safe box) in which the pair of mounting plate portions 180 p are disposed at a position lower than the mounting position of the safe box 90 by the relay unit 162. And a raised position where the safe box 90 placed on the pair of placement plates 180p can be used by the user base 100 (see FIGS. 6 and 8). ) Is supported so as to be movable up and down. Further, a force corresponding to the weight of the safe box 90 placed on the placement frame portion 180 is transmitted to the placement-side movable portion 170, and the coil spring 174 is elastically deformed and placed according to the weight of the safe box 90. The placement side movable part 170 is configured to be displaced with respect to the lift movable part 150. Then, when the pair of horizontal frame portions 186 are lifted from the lowered position while the safe box 90 is placed on the relay portion 162, the safe box 90 on the relay portion 162 is changed over to the pair of placement plate portions 180p. It is placed and supported so that it can move upward. In addition, when the pair of horizontal frame portions 186 are lowered while the safe box 90 is placed on the pair of placement plate portions 180p, the safe box 90 on the pair of placement plate portions 180p is placed on the relay portion 162. It is placed and supported so that it can be changed.

  However, the mounting frame portion is not limited to the above configuration, and may be any configuration that can move up and down while the safe box is mounted and can transmit a force corresponding to the weight of the safe box to the coil spring 174. Further, the configuration in which the mounting frame unit exchanges the safe box is not limited to the above example, and a configuration in which the safe box is pushed and the like can be adopted.

  The weight detection unit 190 is configured to be able to output a weight detection signal corresponding to the displacement of the placement side movable unit 170 with respect to the lift movable unit 150. As the weight detection unit 190, a configuration in which the position of a detector provided on either one of the up-and-down movable unit 150 and the placement-side movable unit 170 is detected by an optical sensor, a magnetic sensor, or the like, a strain sensor is used. Various configurations such as a configuration can be used.

  Further, the rolling element 200 is provided on the elevating movable unit 150, and the receiving piece 210 is provided on the elevating device 130.

  More specifically, the receiving piece 210 is formed on one side of the pair of vertical frame portions 182 in the lifting device 130 from the center of the base plate 132. The receiving piece 210 is bent inward from one side of the pair of vertical frame portions 182 and is formed in an elongated plate shape along the vertical direction.

  Further, rolling elements 200 are provided at both ends of the elevating movable unit 150. The rolling element 200 is formed in a disc shape which is a kind of circular member, and is supported by a rolling element support piece 202 at a position where it can come into contact with the receiving piece 210 from the elevating movable unit 150. Further, the rolling element 200 is supported by the rolling element support piece 202 so as to be rotatable around a rotation axis that coincides with a direction connecting the pair of vertical frame portions 182.

  Around the axis of the elevating drive shaft 142, each rolling element 200 abuts on the receiving piece 210, so that the torsional movement of the elevating movable unit 150 relative to the placement side movable unit 170 is received, and the torsion is suppressed. It has become so. In particular, the rolling element 200 on one side abuts from one rotation direction around the axis of the lifting drive shaft 142 (for example, the upper rolling element 200 abuts from the right rotation direction in FIG. 9) and the rolling element on the other side. The moving body 200 abuts from the reverse rotation direction around the axis of the elevating drive shaft portion 142 (for example, in FIG. 9, the lower rolling element 200 abuts from the left rotation direction). That is, at least one set of rolling elements 200 and receiving pieces 210 are provided so as to be subjected to torsional movement on one side of the elevating movable part 150 with respect to the placement side movable part 170, and at least another set of rolling elements 200 and receiving parts are received. The piece 210 is provided so as to receive a torsional movement toward the other side of the liftable movable portion 150 with respect to the placement-side movable portion 170.

  In addition, the mode in which each rolling element 200 abuts on the receiving piece 210 as described above is also a mode in which a force that pulls the lifting drive shaft 142 by the transmission belt 145a is received. That is, as described above, the transmission belt 145 a is wound so as to pull the elevating drive shaft portion 142 toward the center portion of the base plate 132. For this reason, a force that inclines from the center of the base plate 132 is applied to the lift drive shaft 142. The rolling elements 200 provided in the up-and-down movable part 150 are in contact with the receiving piece 210 from the outside of the base plate 132 toward the center of the base plate 132. For this reason, the force which inclines the raising / lowering drive shaft part 142 as mentioned above is received.

  Further, the rolling element 200 is allowed to move in the vertical direction with respect to the receiving piece 210. That is, the rolling element 200 is formed in a disk shape which is a kind of circular member, and is supported so as to be rotatable around an axis along the horizontal direction. For this reason, the rolling element 200 can move in the vertical direction so as to roll on the surface of the receiving piece 210. Thereby, the up-and-down movable unit 150 can be displaced up and down relatively freely with respect to the placement-side movable unit 170.

  Note that the rolling element 200 may be a circular member such as a disk or a cylinder, or may be a spherical shape or the like as long as it can roll and move with respect to the receiving piece.

  According to the booth side elevating device 130 configured as described above, the elevating movable unit 150 moves up and down together with the elevating movable unit 150. When moving up and down, when the elevating movable unit 150 is torsionally moved with respect to the placement side movable unit 170 due to the rotation of the elevating drive shaft unit 142, one of the rolling elements 200 contacts the receiving piece 210. The force to be twisted is received. Thereby, the twist of the raising / lowering movable part 150 with respect to the mounting side movable part 170 is suppressed. Moreover, the rolling element 200 is in contact with the receiving piece 210 so as to allow the rolling movement of the rolling element 200 relative to the receiving piece 210 in the vertical direction. For this reason, when a force corresponding to the weight of the safe box 90 placed on the pair of placement plate portions 180p is applied to the placement-side movable portion 170, the placement-side movable portion 170 smoothly moves along the vertical direction. Moving. For this reason, it is possible to more accurately reflect the weight of the safe box 90 and to displace the placement side movable unit 170 with respect to the liftable movable unit 150. A weight detection signal is output from the weight detection unit 190 according to the amount of displacement. For this reason, the weight of the safe box 90 can be detected more accurately.

  In the configuration in which the elevating movable unit 150 is moved up and down by the rotational drive of the elevating drive shaft 142, the elevating movable unit 150 is easily rotated by the rotation of the elevating drive shaft 142, and thus the above effect can be said to be effective. However, even in a configuration in which the up-and-down movable unit 150 is moved up and down by other cylinders, so-called linear motors or the like, there is a possibility that relative torsional displacement may occur with the placement-side movable unit 170 above it. You may employ | adopt for such a structure.

  When the coil spring 174 is used as an elastic member interposed between the elevating movable unit 150 and the placement side movable unit 170, the coil spring 174 expands and contracts when the elevating movable unit 150 and the placement side movable unit 170 approach each other. Thus, a twisting force acts between the two. The rolling element 200 and the receiving piece 210 can also receive such a twisting force. Also from this point, the weight of the safe box 90 can be detected more accurately.

  Further, since the rolling element 200 on one side abuts around the axis of the lifting drive shaft 142 from one rotation direction, and the rolling element 200 on the other side abuts around the axis of the lifting drive shaft part 142 from the reverse rotation direction, Even when the movable part 150 is rotated in either the forward or reverse direction, the twist of the elevating movable part 150 relative to the placement-side movable part 170 can be suppressed. Thereby, the weight of the safe box 90 can be detected more reliably and accurately.

  In addition, since the rolling element 200 is a circular member such as a disk or a column, it may be supported so as to be rotatable around a predetermined axis, so that a simple configuration can be achieved.

  In addition, since the rolling element 200 and the receiving piece 210 are in contact with each other in the direction in which the tilt of the lift movable unit 150 is suppressed, the tilt of the lift movable unit 150 can be effectively suppressed.

  In the above embodiment, it has been described that the two rolling elements 200 are in contact with the receiving piece 210 separately, but even in a configuration in which one rolling element or three or more rolling elements are provided. Good. Moreover, it is good also as a structure which the two rolling elements 200 contact | abut on one receiving piece from both surface sides. Furthermore, a receiving piece may be provided on the up-and-down movable unit 150 side, and the rolling element 200 may be provided on the placement-side movable unit 170.
