Fig. 6 is the block diagram of the general configuration of the control system representing the combination balance in present embodiment, the reference identical to the part mark corresponding with Fig. 1.
As shown in Figure 6, possess the CPU portion 21 as calculation control unit, storage part 22, A/D conversion circuit 23, supply conveyer drive circuit portion 24, motor drive circuit portion 25, vibration control circuit portion 26, hopper door drive circuit portion 27 and I/O (input/output) circuit part 28 etc. controlling device 11, and have operation setting display part 29 controlling device 11 connection.
CPU portion 21 as calculation control unit controls each portion, and is combined computing and the zero point correction etc. of weigh-hatching plant 9.
In storage part 22, storage has the operation sequence of combination balance and operating parameter etc. to be placed, and the working region that this storage part 22 is the computing etc. for CPU portion 21.
Analogue signal from top cone weight sensor 18 and weight sensor 10 is converted to digital signal and exports to CPU portion 21 by A/D conversion circuit 23, wherein, this top cone weight sensor 18 is for detecting the weight of the measured object in top cone 3, and this weight sensor 10 is for detecting the weight of the measured object in each weigh-hatching plant 9.
Hopper door drive circuit portion 27, based on the control signal from CPU portion 21, controls the opening and closing of the discharge hopper door 14a of the input materials sluice gate 8a of feeding hopper 8, the discharge materials sluice gate 9a of weigh-hatching plant 9 and set hopper 14.

The detection output of origin sensor 15 is input to CPU portion 21 via I/O circuit part 28, and the de-synchronization state caused because of the overload of stepping motor 4 is detected in CPU portion 21.
Perform to be stored in the operation sequence in storage part 22 by CPU portion 21, control the operation that device 11 control combination scale is overall.
In combination balance, in order to operate described above, needing to arrange multiple operating parameter, this setting is used operation setting display part 29 to carry out by operator, and the operational parameter value arranged is transferred into CPU portion 21 and is stored in storage part 22.Operating parameter has higher limit and the lower limit etc. of the weight range of the measured object in the objective cross weight as the desired value in combinatorial operation and the permissible range corresponding with this objective cross weight, the amplitude of each feed appliance 2,5 and driving time (vibration duration), decision top cone 3.
In the present embodiment, possess the unwinding parts 19 in rotary moving on straight feed appliance 5 integratedly with top cone 3.Therefore, although in the case of measured object is flagelliform object such as such as bean sprout or Cut vegetables etc., sometimes wrapped around one another and be detained by the measured object transfer to straight feed appliance 5 from dispersion feed appliance 2, but due to the unwinding parts 19 that rotate integrally with top cone 3 on straight feed appliance 5 in rotary moving, the measured object being therefore wrapped by unwinding and is successfully transferred towards feeding hopper 8.
Here, the first half of groove 6 in the most of and straight feed appliance 5 of base end side in unwinding parts 19 is the most in rotary moving, i.e. the relatively low position of next door portion 6a is the most in rotary moving with wall part upper surface.Therefore, in the case of measured object is wound around and starts to produce bigger block, measured object block is dragged away by unwinding parts 19 and is moved in same direction, and unwinding parts 19 move further when the bottom of measured object block hangs on the wall part 6a of groove 6.Thus, measured object block is by unwinding, and a part of measured object remains in current groove 6, hangs over the measured object on unwinding parts 19 and is entrained in the groove 6 in direction of rotation downstream.
It addition, the measured object being sometimes wound around is trapped in the crooked position of wall part 6a across the wall part 6a of groove 6 and is grown to bigger block.In this case, unwinding parts 19 owing to being bent to form also rotate with relative track parallel with the crooked position of wall part 6a, the most also the block in the crooked position being trapped in wall part 6a can be given full play to unwinding effect, thus promote that the vibration smoothly of straight feed appliance 5 is transferred.
It addition, when the winding of measured object is the most serious and block is the biggest, the biggest to the load resistance of the rotation process of unwinding parts 19.So, when load resistance increases, stepping motor 4 significantly slows down because of overload or stops sometimes, thus the nominal spinning operation imbalance that stepping motor 4 is from regulation rotary speed.
In this case, in embodiments, by controlling supply conveyer 1 as follows, the stepping motor 4 recovery from overload state is realized.
Fig. 7 is the weight representing the measured object in the top cone 3 to be detected by top cone weight sensor 18 and the imbalance caused because of the overload of stepping motor 4 is detected as the sequential chart of control of supply conveyer 1 on basis, (a) of Fig. 7 illustrates the weight of the measured object in top cone 3, (b) of Fig. 7 illustrates imbalance detection, and (c) of Fig. 7 illustrates that the travelling speed of supply conveyer 1 is i.e. by the feed speed supplying the measured object that conveyer 1 is carried out.
As shown in (a) of Fig. 7, stop supply conveyer 1 when the sense weight of the measured object being supplied in top cone 3 is more than higher limit, and drive supply conveyer 1 when the sense weight of measured object is below lower limit.So, change accordingly with the weight of the measured object being supplied in top cone 3, control the on/off of supply conveyer 1.By this control, supply weight measured object in the range of arranging to top cone 3.
It addition, time stepping motor 4 is lacked of proper care, stop supply conveyer 1 because acting on the load of unwinding parts 19 immediately when detecting, cut off the measured object supply to dispersion feed appliance 2.In cutting off the straight feed appliance 5 of follow-up supply of measured object, proceed the vibration transfer of the measured object of residual.Thus, the measured object hung on unwinding parts 19 is the most rearward sent, and finally departs from from the front end of unwinding parts 19.
Owing to when hanging on unwinding parts 19 and bring all or part of disengaging of measured object of bigger rotary load, the load reduction to stepping motor 4, therefore top cone 3 and the unwinding parts 19 of dispersion feed appliance 2 restart to rotate with original speed.
So, when the imbalance of stepping motor 4 eliminates, supply conveyer 1 starts.When supplying conveyer 1 and starting, measured object restarts to the supply of dispersion feed appliance 2.In this case, as shown in (c) of Fig. 7, if after eliminating the imbalance of stepping motor 4, the supply of the measured object carried out by supply conveyer 1 restarts, then due to its feed speed the most gradually speedup to original feed speed, therefore gradually increase from supply conveyer 1 to the quantity delivered of the measured object of dispersion feed appliance 2.Thus, prevent from causing measured object to be supplied to straight feed appliance 5 because restarting to the supply of the measured object of dispersion feed appliance 2 from supply conveyer 1 quickly, and can prevent in advance because the winding of measured object causes the imbalance of stepping motor 4.
As mentioned above, according to present embodiment, owing to measured object can be transported by making top cone 3 rotate by centrifugal force, even being therefore prone to the measured objects such as the bean sprout of absorption vibration, measured object also will not be detained in top cone 3 for a long time, and measured object can be made radially to send towards foreign side rapidly.Thus, top cone 3 will not be deepened the winding of measured object, under the most scattered state, measured object can be transferred to straight feed appliance 5.
Further, since the measured object being transplanted in straight feed appliance 5 bears the unwinding effect of the unwinding parts 19 rotated against with straight feed appliance 5, measured object therefore can be suppressed to be wound around and be grown to bigger block.
Additionally, when measured object is wound around and starts to produce bigger block, stepping motor 4 is lacked of proper care because of overload, if be detected that this imbalance, the measured object then stopping being carried out by supply conveyer 1 is to the supply of top cone 3, thus can stop and cause block to grow because of the excess supply of measured object.And, when the function of transportation brought because of straight feed appliance 5, measured object block reduces, and stepping motor 4 de-synchronization state eliminate time, top cone 3 and unwinding parts 19 restart to rotate, thus the supply of the measured object carried out by supply conveyer 1 also restarts and returns to common state.
So, can be by by making measured object supply in the way of straight feed appliance 5 suppresses winding to feeding hopper 8 and disperseing fully to weigh-hatching plant 9, it is thus possible to precision is combined metering well.
(other embodiment)
The present invention can also implement as follows.
(1) mode and the quantity of unwinding parts 19 can be arbitrarily set according to the size of measured object or character etc..Such as, unwinding parts 19 are not limited to pole shape, it is also possible to be square rod shape, stringer board shape or other shape.It addition, unwinding parts 19 can also be from linking the form that the bar-shaped turning arm employing being supported in top cone 3 makes the action plate longitudinal wall or a plurality of effect rod downwardly extend in cantilever manner.
(2) by regulating the setting height(from bottom) of unwinding parts 19, change unwinding parts 19 and the interval of groove 6, thus can play suitable unwinding effect corresponding with the kind of measured object.In the structure of above-mentioned embodiment, by the base end part of unwinding parts 19 being linked with top cone 3 by the distance piece of any thickness, thus scalable setting height(from bottom).Or, it is also possible to prepare the multiple unwinding parts 19 that specification is different in advance, and use according to the type classification of measured object.
(3) the overload state of stepping motor 4 can also based on the load current of stepping motor 4, be detected.Furthermore it is also possible to detected the imbalance of the stepping motor 4 caused because of overload by the rotary speed of rotary encoder detection stepping motor 4.
(4) when detecting the overload state of stepping motor 4, it is decelerated to fixing speed by control supply conveyer 1 and reduces the measured object quantity delivered to dispersion feed appliance 2, if the imbalance of stepping motor 4 nonetheless can't be eliminated, then supply conveyer 1 can also be made further to slow down or stop.
(5) when detecting the overload state of stepping motor 4, following control mode can also be used: when being carried out continuously the operating of supply conveyer 1, reverse with the stipulated time and drive top cone 3 and unwinding parts 19, if the overload state of stepping motor 4 can be eliminated by this reverse, then restart to dromic driving, further, if also failing to eliminate overload state in reversing driving, then supply conveyer 1 is stopped.
(6) in the above-described embodiment, by being linked with top cone 3 by unwinding parts 19, top cone 3 and unwinding parts 19 are made to rotate integrally driving but it also may in supply conveyer 1 side, unwinding parts 19 can be installed rotatably.By this installation, it is also possible to implement as follows: make top cone 3 and the most independently rotated driving of unwinding parts 19, and detect the overload state driving motor of unwinding parts 19.In this case, the detection of the overload states driving motor based on unwinding parts 19, carry out supplying the control of conveyer 1, the Spin Control of top cone 3 and the Spin Control of unwinding parts material 19, thus the avoidance that can also carry out overload more meticulously controls.
(7) in the above-described embodiment, although detected the weight of the measured object in top cone 3 by top cone weight sensor 18, but replacement weight sensor, it is also possible to detected the amount of measured object in top cone 3 by such as photoelectric sensor etc..
Industrial applicability
Combination balance involved in the present invention is as by disperseing to transfer combination balance that the measured object being prone to be wound around suppresses measured object block to produce fully and highly useful.
