The movement in the direction (direction of the arrow shown in FIG. 6) from the position of the dish discharge section 130A to the position of the adjacent dish discharge section 130B is referred to as forward movement, and the movement in the reverse direction to forward movement is referred to as backward movement. Each motor is controlled by a control device (not shown).

  The type of the dish 3 is determined in advance according to the price of food and drink placed on the dish 3, the food and drink can be identified by patterns and colors, and the RFID embedded in the dish 3 Individual identification by radio waves is possible by (Radio Frequency Identification), and the type information of the dish 3 is included in the individual identifier. The identification unit 120 includes an antenna 121, and the antenna 121 receives radio waves from the tableware 3, whereby the type of the tableware 3 can be identified. In this embodiment, a case where there are three types of A plate, B plate, and C plate is taken as an example, but two types may be used, or four or more types may be provided.

  Corresponding to the type of the dish 3, the push-out pistons 150 </ b> A to 150 </ b> C of the dish discharge units 130 </ b> A to 130 </ b> C are provided, and the identification unit 120 identifies the type of the dish 3 that has been conveyed by the conveyance unit 110. Extrusion is instructed to the extrusion pistons 150A to 150C corresponding to the identified type by a control device (not shown). The moving unit 140 moves the placed dish 3 forward from the position of the dish discharger 130A to the position of the adjacent dish discharger 130B, and discharges the tableware 3 at the position of the dish discharger 130B to the adjacent dish. Move forward to part 130C. The extrusion pistons 150 </ b> A to 150 </ b> C discharge the plate 3 when the table 3 is moved by the moving unit 140 to the plate discharge units 130 </ b> A to 130 </ b> C corresponding to the type of the plate 3 identified by the identification unit 120. Sorting is performed for each type of tableware 3 by extruding into the stockers 133A to 133C, which are the exit sides of the parts A to C.

  Next, the configuration and operation of the moving unit 140 and the extrusion pistons 150A to 150C of the dish sorting apparatus 100 will be described in detail.

  As shown in FIG. 2, the moving unit 140 mounts the tableware 3 and drives the moving gears 141 and 142 and the moving gears 141 and 142 as two rod-shaped moving means provided at an interval. A drive gear 144 and a moving gear motor 143 that drives the drive gear are provided. In addition, the moving unit 140 may include a guide member 151 that is disposed over all the dish discharging units and supports the side rear surface of the tableware dish 3. As shown in FIGS. 3 and 4, the moving gears 141 and 142 have a moving distance corresponding to one tray discharging portion (one pitch), and the tray discharging portions 130 </ b> A and B that are two tray discharging portions. Or, it is provided with such a length as to extend over the dish discharge sections 130B and 130C. The moving unit 140 drives the moving gears 141 and 142 with the moving gear motor 143 and the driving gear 144, for example, as shown in FIGS. 9 and 10, the tableware placed on the moving gears 141 and 142. 3 is moved by one pitch from the position of the dish discharge section 130A to the position of the adjacent dish discharge section 130B, and at the same time, the tableware 3 at the position of the dish discharge section 130B is moved by one pitch to the adjacent dish discharge section 130C. Let Thereby, the several tableware located in dish discharge part 130A, B can be simultaneously moved forward. In addition, the moving unit 140 includes slide rails 145 and 146 as lift means and a lift lever 147. The slide rails 145 and 146 are connected to the lift lever 147, and the slide rails 145 and 146 are connected to the moving gears 141 and 142. When moving the tableware 3 forward, the moving unit 140 lifts the slide rails 145 and 146 with the lift lever 147 to lift the moving gears 141 and 142 upward and rotate the moving gear motor 143 to drive. By moving the moving gears 141 and 142 forward through the gear 144, the tableware 3 placed on the moving gears 141 and 142 can be moved by one pitch. The moving unit 140 lowers the slide rails 145 and 146 downward by the lift lever 147, thereby lowering the moving gears 141 and 142, and reversely rotating the moving gear motor 143 to move the moving gear via the drive gear 144. 141 and 142 are moved backward. In this case, by lowering the moving gears 141 and 142, the tableware 3 is held and placed on the guide member 151 and is separated from the moving gears 141 and 142. For this reason, when the moving gears 141 and 142 move backward, the tableware 3 does not move, and remains in the dish discharge unit 130 after the forward movement. In this way, the movement gears 141 and 142 of the moving unit 140 continuously move forward and backward alternately so that the plurality of tablewares located in the dish discharge units 130A and 130B are simultaneously moved forward by one pitch. be able to.

  Further, as shown in FIG. 2, the extrusion pistons 150 </ b> A to 150 </ b> C are connected to the extrusion motors 131 </ b> A to 131 </ b> C, the drive gears connected to the extrusion motors 131 </ b> A to C, and the drive gears. And a link portion that drives to extrude. The push-out pistons 150A to 150C are arranged in the stockers 133A to C, which are the outlets of the tray discharge units A to C, when the moving gears 141 and 142 of the moving unit 140 are moving backward. Extrude into.

  Next, how the tableware tray 3 moves in the plate sorting apparatus 100 will be described with reference to FIGS. 1 and 5 to 13.

  As shown in FIG. 1, the dishes 3 stacked and loaded in the dish loading unit 160 are conveyed one by one by a screw 112 of the conveyance unit 110 driven by the conveyance unit motor 111. When the dish 3 passes over the identification unit 120, the antenna 121 receives an RFID radio wave from the table 3 and the identification unit 120 identifies the type of the dish 3. A control device (not shown) instructs extrusion pistons 150 </ b> A to 150 </ b> C corresponding to the type of the dish 3 to perform extrusion. Thereafter, when the dish 3 is transported to the position of the dish discharge portion 130A located at the end of the screw 112, the dish 3 is placed on the upper surfaces of the moving gears 141 and 142 as shown in FIG. Next, the table gear 3 mounted on the moving gears 141 and 142 is moved forward by one pitch by rotating the moving gear motor 143 and moving the moving gears 141 and 142 forward via the drive gear 144. Let Thereby, as shown in FIG. 6, the dish 3 moves forward from the dish discharge part 130A to the dish discharge part 130B. Thereafter, the slide rails 145, 146 are lowered downward by the lift lever 147, thereby lowering the moving gears 141, 142 downward and rotating the moving gear motor 143 in the reverse direction as shown in FIG. Then, the moving gears 141 and 142 are moved backward. In this case, by lowering the moving gears 141 and 142 downward, as shown in FIGS. 7 and 8, the tableware 3 is placed on the guide member 151 and is separated from the moving gears 141 and 142. . For this reason, when the moving gears 141 and 142 move backward, the tableware 3 does not move, and remains in the dish discharge unit 130 after the forward movement. Since the moving gears 141 and 142 are lowered, when moving backward, the moving gears 141 and 142 can move without contacting the tableware 3. Further, when the moving gears 141 and 142 are retracted, the next tableware dish 3 is conveyed onto the pushing piston 150A of the dish discharging unit 130A. Thereafter, the slide rails 145 and 146 are lifted by the lift lever 147 so that the moving gears 141 and 142 are lifted upward to place the dish 3 in the dish discharging unit 130A and the dish discharging unit 130B. By rotating the motor 143 and moving the moving gears 141 and 142 forward via the drive gear 144, the tableware 3 placed on the moving gears 141 and 142 can be moved by one pitch. As a result, as shown in FIG. 10, the tableware tray 3 moves forward from the plate discharger 130A to the plate discharger 130B, and the tableware tray 3 moves forward from the plate discharger 130B to the plate discharger 130C. After that, when the dish 3 is conveyed to the dish discharge unit 130C corresponding to the type, the pusher piston 150C is moved backward by the moving gears 141 and 142 of the moving unit 140 as shown in FIG. Occasionally, the dish 3 is pushed out into the stocker 133C, which is the outlet side of the dish discharge section C, and lifted. Three holding pieces 132 are provided at the lower end portion of the stocker 133C of the dish discharge portion C. When the tableware dish 3 is raised by the pushing piston 150, the holding piece 132 is pivotally supported so as to jump up. When the pushing piston 150 is lowered, the holding piece 132 is hooked on the peripheral portion of the tableware 3 so that the tableware 3 is held. Thereby, even if the extrusion piston 150 descends, the stacked tableware dishes 3 are held by the holding pieces 132 of the dish discharge section.

  By continuously performing the operations as described above, the dish 3 located in the dish discharge units 130A and 130B can be moved forward by one pitch and moved to the dish discharge units 130B and 130C, respectively. When moved to the tray discharge unit 130 corresponding to the type of the plate 3, the plate is pushed out by the pushing piston 150 and held in the stockers 133 </ b> A to 133 </ b> C of the plate discharge unit 130. As shown in FIG. 12, when the dish 3 is conveyed to the dish discharge part 130B or the dish discharge part 130C corresponding to the type, the extrusion piston 150B and the extrusion piston 150C are moved to the moving part as shown in FIG. When the moving gears 141 and 142 of 140 are moving backward, the tableware tray 3 is pushed out into the stocker 133B and C, which is the outlet side of the tray discharge section B and the tray discharge section C, and lifted. In addition, when the tableware 3 of the type corresponding to the dish discharge part 130A located at the terminal end of the screw 112 is conveyed from the screw 112 and the tableware 3 is placed on the guide member 151, the moving gears 141 and 142 are used. Is moving backward, the push-out piston 150A of the dish discharge section A pushes the tableware dish 3 into the stocker 133A on the outlet side of the dish discharge section A, so that the tableware dish 3 becomes the dish discharge section. A holding piece 132 of A is held.

  As described above, the moving unit 140 alternately performs forward movement and backward movement, and the extrusion by the pushing piston 150 is performed at the timing of the backward movement of the moving part 140, thereby controlling the timing of the moving part 140 and the pushing piston 150. It becomes easier, and the sorting for each type of the dish 3 can be performed reliably.

<Additional Examples>
Next, a configuration when a dish movement restricting unit 170 that supports tableware is added to the configuration of the dish sorting apparatus shown in the above embodiment will be described as an additional embodiment. 14 and 15 show the configuration and operation explanatory diagram of the dish sorting apparatus 100A according to an additional embodiment. FIGS. 14 (a) and 15 (a) show a part of a plan view of the moving part of the dish sorting apparatus 100A, and FIGS. 14 (b) and 15 (b) show operation explanatory views of the dish sorting apparatus 100A. Show. The configuration of the dish sorting apparatus 100A in the additional embodiment is the same as that of the dish sorting apparatus 100 shown in the above embodiment except for the configuration of the dish movement restricting portion 170 and its link portion, and therefore, different parts. explain.

  In an additional embodiment, when the dish 3 is transported and arranged at the position of the dish discharge unit 130A located at the terminal end of the screw 112 shown in FIG. 1, or when the dish discharge unit 130B or 130C is moved by the moving unit 140. In order to prevent the position shift of the tableware plate 3 that occurs when the position tableware plate 3 is moved, a plate movement restriction unit 170 that restricts the movement of the tableware plate 3 is provided. The dish movement restricting unit 170 is not provided in the dish discharging units 130B and 130C, but is provided only corresponding to the dish discharging unit 130A, so that the position of the dish discharging unit 130A located at the terminal end of the screw 112 shown in FIG. Therefore, it is possible to prevent the tableware 3 from being displaced in the forward direction (the forward direction is the same as the moving direction of the moving unit 140) that occurs when the tableware 3 is transported and arranged. In this additional embodiment, since the dish movement restricting unit 170 is provided for each dish discharging unit 130, the dish movement restricting units 170A and 170B are associated with the dish discharging units 130A and 130B, respectively. . By providing the dish movement restricting unit 170 for each dish discharging unit 130, when the tableware dish 3 is arranged in each dish discharging unit 130, the dish movement restricting unit 170 moves in the forward direction of the tableware dish 3 (by the moving unit 140. In order to restrict the movement in the movement direction), the dish 3 stays at the position of the dish discharge part 130 and does not shift from the pushing position of the dish discharge part 130. The failure to push up the dish 3 can be prevented, and the dish 3 can be pushed up smoothly.

  As shown in FIGS. 14 (a) and 14 (b), the configuration of the dish movement restricting portion 170 includes a contact portion 171 that contacts the tableware dish 3, and a support for moving the contact portion 171 up and down. And a drive shaft 173 that drives the support portion 172 up and down. The drive shaft 173 is connected to the lift lever 147, and when the slide rails 145 and 146 are lowered downward by the lift lever 147 and the moving gears 141 and 142 are lowered downward, that is, the table 3 is moved by the moving portion 140. When the tray is not moved, the dish movement restricting portion 170 drives the drive shaft 173 by the lift lever 147 to move the contact portion 171 upward from below via the support portion 172, and the tip of the contact portion 171. The portion is brought into contact with the side surface of the thread bottom of the tableware dish 3, so that the movement of the tableware dish 3 in the forward direction is restricted. Further, when the slide rails 145 and 146 are lifted by the lift lever 147 and the moving gears 141 and 142 are lifted upward, the dish movement restricting unit 170 is driven by the lift lever 147 by the drive shaft 173 so that the support portion 172 is moved. The contact portion 171 is moved downward from above the contact position of the tableware dish 3. As a result, as shown in FIGS. 15A and 15B, when the tableware 3 is moved in the forward direction by the moving gears 141 and 142, the contact portion 171 prevents the tableware 3 from moving forward. It is evacuated to the lower position where it does not.

  As shown in FIG. 14A, the tips of the contact portions 171 </ b> A and B of the dish movement restricting portion 170 are in contact with a part of the advancing side of the tableware plate 3 so that the forward movement of the tableware plate 3 can be restricted. For example, by forming the shape similar to a part of the side surface of the yarn bottom, it is possible to easily contact the side surface portion of the yarn bottom of the dish plate 3. As a moving direction of the support part 172 of the dish movement restricting part 170, the movement of the tableware dish 3 may be restricted by moving from above to below as well as moving from below. When regulating by moving from the upper side to the lower side, when the contact part 171 is in the upper position, the position is set so as not to obstruct the forward movement of the tableware 3 and the drive shaft 173 is also provided at the upper side. deep. Further, the dish movement restricting portion 170 is provided on the side so as not to interfere with the forward movement of the tableware dish 3, and the support portion 172 is translated in the horizontal direction in the horizontal direction to restrict the forward movement of the tableware dish 3. You may make it the structure which does. In this case, the direction of movement of the drive shaft is set in accordance with it.

  Next, the movement of the tableware dish 3 in the dish sorting apparatus 100A and the state of movement restriction will be described with reference to FIGS.

  As shown in FIGS. 14 (a) and 14 (b), as in the above-described embodiment, the tableware 3 is conveyed one by one by the screw 112 of the conveyance unit 110 (not shown), and the tableware 3 is a guide member. 151 is placed on the extrusion piston 150A of the tray discharger 130A. At that time, the dish movement restricting portions 170A and B move the contact portions 171A and B upward from below through the support portions 172A and B by driving the drive shafts 173A and B by the lift lever 147. The tip portions of 171A and 171B are brought into contact with the side surface of the yarn bottom of the tableware plate 3, thereby restricting the movement of the tableware plate 3 in the forward direction. On the other hand, the moving unit 140 is interlocked with the timing of movement restriction, and the lift lever 147 lowers the slide rails 145 and 146 downward, lowers the moving gears 141 and 142 downward, and reversely rotates the moving gear motor 143. The moving gears 141 and 142 are moved backward via the drive gear 144. At this time, if the dish 3 is in the dish discharge portion 130A corresponding to the type, the pusher piston 150A moves the moving gears 141 and 142 of the moving portion 140 backward, and the dish movement restricting portion 170A When the movement is restricted, the tableware 3 is pushed out into the stocker 133A which is the outlet side of the plate discharge section A and lifted. At this time, the dish movement restricting portion 170A does not restrict the movement in the push-up direction of the extrusion piston 150A. As described above, the dish movement restricting portions 170A and 170B are configured to restrict only the movement of the tableware dish 3 in the forward direction, and do not restrict the other direction.

  Next, the drive shafts 173A and B are driven by the lift lever 147, and the contact portions 171A and B are moved downward from above the contact position of the tableware plate 3 via the support portions 172A and B. Movement restrictions are lifted. In conjunction with the release timing of the movement restriction, the slide rails 145 and 146 are lifted by the lift lever 147 and the moving gears 141 and 142 are lifted upward to load the dish 3 in the dish discharge part 130A and the dish discharge part 130B. 15A and 15B, the moving gear motor 143 is rotated and the moving gears 141 and 142 are moved forward via the drive gear 144, so that the moving gears 141 and 142 are moved forward. 1 is moved forward by 1 pitch.

  Thereafter, the movement restriction by the movement restriction portions 170A and B, the backward movement of the movement gears 141 and 142, the push-up of the push pistons 150A to 150B, the release of the movement restriction by the movement restriction portions 170A and B, and the movement gears 141 and 142 are performed. Repeat the forward movement of the dish 3 by. At this time, the movement restriction portions 170A and B perform movement restriction release and movement restriction in conjunction with the up and down movements of the movement gears 141 and 142 by the lift lever 147, thereby moving the plate movement restriction portions 170A and B and the movement. The operation timings of both the gears 141 and 142 can be easily matched.

  By continuously performing the operations as described above, when the tableware dish 3 is disposed in the dish discharge unit 130, the dish movement restriction unit 170 is placed on the tableware dish 3 positioned in the dish discharge unit 130. In order to restrict the movement of the tableware tray 3 in the forward direction (the moving direction of the moving unit 140), the tableware plate 3 stays at the position of the plate discharging unit 130 and is displaced from the pushing position of the plate discharging unit 130. Therefore, it is possible to prevent the push-up of the tableware 3 by the pushing piston 150 and to smoothly push up the tableware 3. Further, it is possible to prevent clogging of the forward movement due to the positional deviation of the tableware 3 after the failure to push up the tableware 3.

  The moving unit 140 alternately performs forward movement and backward movement, and the movement restriction of the tableware 3 by the dish movement restriction part 170 and the pushing by the pushing piston 150 are performed at the timing of the backward movement of the movement part 140, thereby moving the moving part 140. The timing control of 140, the dish movement restricting unit 170, and the push-out piston 150 is also simplified, so that the sorting of the dishes 3 by type can be performed reliably.

  When the dish movement restriction unit 170 is provided only for the dish discharge unit 130A, the dish plate 3 generated when the dish plate 3 is conveyed and arranged at the position of the dish discharge unit 130A located at the terminal end of the screw 112. Can be prevented. In addition, when the dish movement restriction unit 170 is provided for each dish discharge unit 130, when the tableware dish 3 is arranged in each dish discharge unit 130, the dish movement restriction unit 170 moves forward (moves) the tableware dish 3. In order to restrict the movement in the direction of movement by the portion 140, the tableware pan 3 stays at the position of the plate discharge portion 130 and does not shift from the push position of the plate discharge portion 130. Failure to push up the tableware dish 3 due to ~ C can be prevented, and the tableware dish 3 can be pushed up smoothly. 14 and 15 show only the configuration of the dish discharge sections 130A and 130B, the dish movement restricting section 170 may be provided in the dish discharge section 130C, or any one of the dish discharge sections 130 may be provided. Alternatively, the dish movement restricting portion 170 may be provided.

  The dish sorting apparatuses 100 and 100A described above are configured as a single unit, but may be provided inside a dish cleaning apparatus or a dish transport apparatus, for example.

  According to the above embodiment and the additional embodiment, the dish discharge unit 130 is provided for each type of the tableware dish 3, and the moving unit 140 places the tableware dish 3 from the dish discharge unit 130A or B. It can move reliably to the adjacent dish discharge part 130B or C. Thereafter, when the table plate 3 is moved by the moving unit 140 to the plate discharging unit 130 corresponding to the type of the table plate 3 identified by the identifying unit, the pushing piston 150 moves the table plate 3 to the plate discharging unit 130. Since it can extrude to the exit side, the dish 3 can be reliably stopped by the dish discharge part 130 which is a stop position, and can be extruded. Thereby, the stop position of the dish 3 does not deviate from the dish discharge part 130, the timing control of the moving part 140 and the pushing piston 150 becomes easier, and the sorting for each type of the dish 3 is ensured. It can be carried out. In this case, when the dish 3 is moved to the dish discharge unit 130 that does not correspond to the type of the dish 3, it can be moved to the next dish discharge unit 130 by the moving unit 140. It will be moved to the corresponding dish discharge part 130 one after another.

  Further, the dish 3 is placed and moved on the movement gears 141 and 142 which are two rod-shaped moving means, and the pushing piston 150 is moved from the gap between the two rod-shaped movement gears 141 and 142 to the bottom of the tableware 3. Since the movement gears 141 and 142 do not get in the way when the extrusion piston 150 is extruded, for example, the movement of the tableware 3 and the extrusion can be performed alternately. Each sorting can be performed reliably.

  Since the moving part 140 can perform the movement of the dish 3 to the adjacent dish discharging part 130 at the same time in all of the dish discharging parts 130A and B, in the dish discharging part 130 arranged in a row, A plurality of tableware 3 can be moved one after another.

  Further, the moving gears 141 and 142 move (advance) from the dish discharging part 130A or B to the adjacent dish discharging part 130B or C. At this time, the slide rails 145 and 146 and the lift lever 147 are moved to the moving gear 141. 142, and the slide rails 145 and 146 and the lift lever 147 lower the moving gears 141 and 142 downward, so that the moving gears 141 and 142 are moved to the adjacent dish discharge portions 130B or C. To return to (retract from) the dish discharge section 130A or B. The push-out piston 150 holds the dish 3 located in the dish discharge section 130 when the moving gears 141 and 142 are lowered downward by the slide rails 145 and 146 and the lift lever 147, and the dish discharge section 130 In the case of the dish discharge unit 130 corresponding to the type of the tableware dish 3, the tableware dish 3 can be pushed out to the dish discharge unit 130. Thereby, the moving gears 141 and 142 move upward when moving forward, and move downward when moving backward. For this reason, since the guide member 151 holds the tableware 3 at the time of reverse drive, the tableware 3 can be moved forward one after another without the tableware 3 retracting.

  Since the moving gears 141 and 142 are disposed over at least two of the dish discharge units 130, the plurality of tableware dishes 3 positioned in the dish discharge unit 130 can be simultaneously moved by the movement gears 141 and 142.

  Moreover, although the guide member 151 is arrange | positioned over all the dish discharge parts, you may make it provide the guide member 151 for every dish discharge part 130. FIG. Furthermore, when the moving gears 141 and 142 move forward, the guide member 151 may guide the side back surface of the tableware 3 and the like. Thereby, the movement (advance) from the dish discharge part 130A or B to the adjacent dish discharge part 130B or C can be assisted.

  According to the additional embodiment, since the dish movement restricting unit 170 that restricts the movement of the tableware dish 3 in the moving direction of the moving unit 140 with respect to the tableware dish 3 located in the dish discharging unit 130 is provided, When the dish is placed on the dish discharge unit 130, the dish movement restriction unit 170 restricts the movement of the tableware dish 3 in the movement direction of the movement unit 140 with respect to the tableware dish 3 located in the dish discharge unit 130. The dish plate 3 stays at the position of the dish discharge unit 130 and is not displaced with respect to the pushing position of the plate discharge unit 130. 3 can be smoothly pushed up. Further, it is possible to prevent clogging of the forward movement due to the positional deviation of the tableware 3 after the failure to push up the tableware 3.

  According to an additional embodiment, the tableware 3 in the moving direction of the moving unit 140 with respect to the tableware 3 positioned in the plate discharging unit 130 while being interlocked with the operation of the moving gears 141 and 142 by the lift lever 147. Therefore, the operation timing of the dish movement restricting unit 170 is set in accordance with, for example, the timing at which the moving gear means not moving the tableware 3 at the operation timing of the moving unit 140 is lowered. By restricting, the dish plate 3 will not be displaced with respect to the pushing position, so that it is possible to prevent failure of pushing the table plate 3 by the pushing piston 150 and to push up the table plate 3 smoothly. . Further, it is possible to prevent clogging of the forward movement due to the positional deviation of the tableware 3 after the failure to push up the tableware 3.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, the dish discharge unit 130 is provided at least for each type of the dish 3, but a plurality of dish discharge units 130 of the same type may be provided. In this case, control may be performed so that the dishes 3 are alternately sorted so that the number of sheets to be sorted into each of the same type of dish discharge units 130 is equal.

  Moreover, in the said Example and the additional Example, although the tableware plate 3 demonstrated the round shape thing, a square shape other than that and a polygonal shape may be sufficient. In this case, the shape of the contact part 171 of the dish movement restricting part 170 can be configured to match the shape of the dish.

  The push-out pistons 150A to 150C place the slide plates 145 and 146 and the tableware pan 3 positioned at the tray discharge portions 130A to 130C when the moving gears 141 and 142 are lowered by the lift lever 147. You may make it do.
