Had folds up action.Qualified product transports subsequent processing by discharge component 3, and underproof product is then by useless coin tray filling machine
Structure 4 is processed.
During useless 4 sabot of coin loading mechanism, first the first useless coin disk 405 and the second useless coin disk 406 are placed on supporting plate 402
On, on the coin disk 405 that gives up to first, all of coin incorporating section 407 is numbered successively according to order from left to right, and is marked
For one, two, three, four, five, six, seven, eight, nine, on the coin disk 406 that gives up to second, all of coin incorporating section 407 is according to from left to right
Order be numbered successively, and be labeled as one, two, three, four, five, six.Secondly, 404 drive screw of control module controlled motor
403 motions, screw mandrel 403 drive supporting plate 402 to move left and right so that on supporting plate 402, the first useless coin disk 405 puts in place, the first useless coin disk
405 according to eight → six → tetra- → bis- → mono- → tri- → five → seven → nine order sabot, complete the first sabot for giving up coin disk 405
Afterwards, the useless coin disk for filling coin is manually removed, and vacant useless coin disk is placed on the position of the first useless coin disk 405 on supporting plate 402
Put.Then, 404 drive screw 403 of control module controlled motor is moved right, and screw mandrel 403 drives supporting plate 402 to move left and right, and makes
Obtain the second useless coin disk 406 on supporting plate 402 to put in place, the second useless coin disk 406 is filled according to one → tri- → five → six → tetra- → bis- order
Disk, after the second useless coin disk 406 completes sabot, manually removes the useless coin disk for filling coin, and vacant useless coin disk is placed on support
The position of the second useless coin disk 406 on plate 402.Finally, repeat aforesaid operations, constantly carry out coin sabot of giving up.
In addition, before the first useless coin disk 405 repeats sabot operation, control module gathers the first jogging sensor 424
Micro-tremor signal, and judge whether the first useless coin disk 405 is in place according to micro-tremor signal, if the first useless coin disk 405 is in place, repeat first
The sabot operation of useless coin disk 405, if first gives up coin disk 405 without in place, checks reason and whether artificial judgment needs to stop behaviour
Make.Before the second useless coin disk 406 repeats sabot operation, control module is needed to gather the micro-tremor signal of the second jogging sensor 425,
And judge whether the second useless coin disk 406 is in place according to micro-tremor signal, if the second useless coin disk 406 is in place, repeat the second useless coin disk 406
Sabot operation, if second gives up coin disk 406 without in place, check reason and whether artificial judgment need to stop operation.
During sabot, next column coin incorporating section after previous column coin incorporating section 407 will be waited to fill coin, can be just carried out
407 sabot operation, judges that the method whether coin incorporating section 407 fills is as follows:First by each column coin incorporating section 407 most
Big storage number of coins is set to predetermined value, then in row coin 407 sabot of incorporating section, main control module collection charging sensing
The conveying number of coins of device 409, last main control module judge whether the conveying number of coins for gathering reaches predetermined value, if reaching
Arrive, this row coin incorporating section 407 has been filled with, the sabot operation of next column coin incorporating section 407 is carried out, if not yet reaching, this
Storage coin is continued in one row coin incorporating section 407, until filling.
In addition to the implementation, the utility model can also have other embodiment.All employing equivalents or equivalent change
The technical scheme to be formed is changed, all falls within the protection domain of the utility model requirement.
