Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the related art, according to the set fixed discharging time length of the bins, the discharging action is sequentially executed on all bins, the first bin starts to discharge, when the first bin reaches the discharging time length, the second bin starts to discharge, when the second bin reaches the discharging time length, the following bins continue to discharge, however, if some bins are filled with materials, and if some bins are not filled with materials, the discharging efficiency is reduced according to the mode of discharging all bins one by one.

To this end, the present invention provides a discharge control method, which may be performed by a discharge control apparatus or software and/or hardware therein, and which may be applied to a storage system of a mixing station, and which may mix concrete, aggregate required for the concrete, and the like, may be stored in the storage system, and which may include a discharge control apparatus, a plurality of bins, a conveyor belt, and a storage bin, to which the discharge control apparatus controls the bins to discharge the material to the conveyor belt for transmission to the storage bin for storage. The discharge control method of the present invention is described below with reference to fig. 1 to 3.

The embodiment provides a discharging control method, as shown in fig. 1, which at least comprises the following steps:

step 110, determining whether each bin of a plurality of bins in the current cycle needs to execute a discharging action, and obtaining a first target bin which does not need to execute the discharging action and/or a second target bin which needs to execute the discharging action, wherein the first target bin comprises a bin without material, and the second target bin comprises a bin with material; in the target direction, one cycle is from the first bin to the last bin of the plurality of bins.

And 120, under the condition that the second target bin is obtained, controlling the second target bin to execute the unloading action in the current cycle.

In practice, as shown in fig. 2, a plurality of bins 201 may be arranged sequentially above the conveyor belt 202. The plurality of bins are provided with sequence numbers ordered along the target direction. The target direction is indicated by solid arrows in the figure. The sequence number of each bin increases along the target direction, the sequence number of each bin may be an arithmetic progression increasing along the target direction, the sequence number of the first bin is 1, and the tolerance is 1. For example, the number of bins is n, and the sequence number of n bins ordered along the target direction may be number 1, number 2, number 3, number 4, … …, number n-1, number n. In fig. 2, n is shown as 6. The conveyer belt is located the discharge opening below of feed bin.

The above-described discharge action may be used to discharge the material in the bin to the conveyor belt. The direction of movement of the conveyor belt (indicated by the dashed arrow in fig. 2) is towards the side of the target location to be reached, e.g. the side of the storage silo in the storage system, and the conveyor belt may, for example, comprise a horizontal conveyor belt, which may be located below the discharge opening of the silo, and an inclined conveyor belt. After the bin is unloaded, the material is conveyed to the inclined conveying belt by the horizontal conveying belt, and then the material is conveyed to the target position by the inclined conveying belt.

Here, the target direction may be a direction opposite to the running direction of the conveyor belt. The cycle is repeated from a first bin to a last bin of the plurality of bins along the target direction, and then from the first bin to the last bin of the plurality of bins again along the target direction. Based on this, one cycle is taken from the first bin to the last bin of the plurality of bins in the target direction.

Along with the feeding of feed bin, in every circulation, the material is different in each feed bin, has the material in some feed bins, can carry out the action of unloading in order to unload to the feed bin according to the demand, and then no material in some feed bins, unnecessary execution action of unloading, if also carry out the action of unloading to the feed bin of unloading, can influence the efficiency of unloading, for this reason, in this embodiment, in every circulation, do not carry out the action of unloading to the feed bin of unloading, do benefit to improvement efficiency of unloading. Based on the above, among the plurality of bins, the bin that is not required to perform the discharging action in the current cycle is the first target bin, and the obtained first target bin at least contains the bin without material. Among the plurality of bins, the bin in the current cycle in which the discharging action is to be performed is a second target bin in which the obtained second target bin is filled.

The plurality of bins may be all first target bins, all second target bins, or both first target bins and second target bins. After determining whether each bin of the plurality of bins in the current cycle requires a discharge action, when a second target bin is present in the plurality of bins, the second target bin in the current cycle is controlled to perform the discharge action. In each cycle, the first target bin and the second target bin in the multiple bins are different, so that the discharging sequence of the bins for which discharging actions are required to be executed in each cycle is also different, dynamic adjustment of the discharging sequence is realized, the actual situation of each bin is adapted, and the discharging efficiency of the discharging control mode of automatic cycle discharging is higher.

In this embodiment, whether each bin of the multiple bins in the current cycle needs to perform a discharging action or not may be determined respectively, so as to obtain a first target bin that does not need to perform a discharging action and/or a second target bin that needs to perform a discharging action, where the first target bin includes a bin without material, that is, includes an empty bin, and the second target bin includes a bin with material, so that the empty bin may be skipped, and the second target bin in the current cycle is controlled to perform a discharging action, thereby greatly improving the discharging efficiency.

In an exemplary embodiment, determining whether each bin of the plurality of bins in the current cycle needs to perform a discharging action, resulting in a first target bin that does not need to perform a discharging action and/or a second target bin that needs to perform a discharging action, as shown in fig. 3, may include:

step 310, determining a level status of each of the plurality of bins in the current cycle, the level status including no material, full with material, and not full.

Illustratively, determining a level status of each of the plurality of bins in the current cycle may include: the level status of each of the plurality of bins in the current cycle is determined based on the sensed signal of the first sensor at the lower level limit and the sensed signal of the second sensor at the upper level limit in each bin.

Wherein the upper limit of the material level is the maximum material level of the bin. The bin level reaches the upper limit of the bin level, indicating that the bin is full, at which time the bin is full. The lower level limit is the minimum level of the bin. The bin level of the bin is at the lower limit of the bin level, which indicates that the bin is empty, and at this time, the bin is empty.

In practical applications, a first sensor located at a lower limit of the material level and a second sensor located at an upper limit of the material level may be provided in each bin, respectively. The first sensor and the second sensor may be level switches. In order to avoid the in-process to feed the feed bin, to first sensor and second sensor impact force too big, can set up the baffle respectively in first sensor and second sensor top, can cushion the impact force of material through the baffle, avoid first sensor and second sensor to damage because of the impact of material.

For each bin, the bin level state can be determined based on the sensing signals of the first sensor and the sensing signals of the second sensor in the bin, wherein if the sensing signals of the first sensor and the sensing signals of the second sensor are both indicative of not contacting the material, the bin level state of the bin is empty, if the sensing signals of the first sensor and the sensing signals of the second sensor are both indicative of contacting the material, the bin level state of the bin is full and full, and if the sensing signals of the first sensor are indicative of contacting the material and the sensing signals of the second sensor are indicative of not contacting the material, the bin level state of the bin is full and not full. In this way, the level status of each bin can be accurately determined by the first sensor arranged at the upper level limit and the second sensor arranged at the lower level limit in the bin.

For a bin that is full and has material, if feeding to the bin is continued, a flash condition may occur, and for this reason, the discharge control method of this embodiment may further include: and when the material level state of the bin is changed from full to full from full, sending an alarm signal for stopping feeding. Therefore, in the feeding process, when the bin is full, the staff is prompted to stop feeding through an alarm, and flash is avoided. And when the material level state of the material bin is changed from material-filled state to material-free state, sending a prompt signal of feeding. So, at the in-process of unloading, when the feed bin is unloaded, can indicate the staff feeding, the staff can in time feed according to the demand to promote the efficiency of unloading.

Step 320, determining whether each bin of the multiple bins in the current cycle needs to execute a discharging action based on a preset bin priority, so as to obtain a first target bin and/or a second target bin; among the preset bin priorities, the bin with the material and the full bin has the highest priority and the bin without the material has the lowest priority.

In practical application, along with feeding in to the feed bin, the material level state in the feed bin constantly changes, when the feed bin has the material and when full, namely the feed bin is full, can not continue feeding again, need unload as early as possible to improve the efficiency of unloading, consequently, can carry out the action of unloading to full bin preferentially, when the feed bin does not have the material, namely the feed bin is empty, can skip empty bin, does not carry out the action of unloading to save time, in order to improve the efficiency of unloading. Based on the above, the priority of the bin is the highest of the bins with materials and full, the priority of the bin with materials and not full is the highest, and the priority of the bin without materials is the lowest. Therefore, the unloading motion can be preferentially executed for the full bin, and then the unloading motion can be executed for the bin with the material and the bin without the material, so that the unloading efficiency is greatly improved, and the automation degree of unloading is improved.

With the change of the material level state in the bins, the first target bin and the second target bin of the bins in each cycle also change, some bins change from having material to not having material, the second target bin in the current cycle may change to the first target bin in the next cycle, some bins change from not having material to having material, and the first target bin in the current cycle may change to the second target bin in the next cycle. In this way, empty bins that can be skipped can be added or removed in conjunction with changes in the fill level status.

In an exemplary embodiment, based on a preset bin priority, determining whether each bin of the plurality of bins in the current cycle needs to perform a discharging action, to obtain a first target bin and/or a second target bin, a specific implementation manner may include:

under the condition that a plurality of bins exist with materials and are full in the current circulation, determining the bins which are full with materials in the plurality of bins as second target bins; if the last bin with the material and the full bin is provided with the material and the unfinished bin along the target direction, determining the bin with the material and the unfinished bin after the last bin with the material and the full bin as a second target bin; and determining the bin outside the second target bin in the plurality of bins as the first target bin.

And under the condition that the plurality of bins are not provided with the materials and the bins are full in the current circulation, if the plurality of bins are provided with the non-materials, determining the non-materials bins as first target bins, and if the plurality of bins are provided with the materials and the bins are not full, determining the materials and the bins are provided with the materials and the bins are not full as second target bins.

To the condition that there is full storehouse in a plurality of feed bins, for example, in 6 feed bins, along the target direction, no. 1 feed bin is the feed bin that has the material and not full, no. 2 feed bin is full, no. 3 feed bin is empty, no. 4 feed bin is full, no. 5 feed bin and No. 6 feed bin are the feed bin that has the material and not full, then can confirm that No. 2 feed bin and No. 4 feed bin need carry out the action of unloading, no. 5 feed bin and No. 6 feed bin need carry out the action of unloading, no. 1 feed bin and No. 3 feed bin need not carry out the action of unloading. Then the discharge sequence of the current cycle may be bin number 2, bin number 4, bin number 5 and bin number 6.

To the condition that there is not full storehouse in a plurality of feed bins, still for example, in 6 feed bins, along the target direction, no. 3 feed bins are empty, no. 1 feed bins, no. 2 feed bins, no. 4 feed bins, no. 5 feed bins and No. 6 feed bins are the feed bins that have the material and are not full, then No. 3 feed bins need not carry out the action of unloading, no. 1 feed bins, no. 2 feed bins, no. 4 feed bins, no. 5 feed bins and No. 6 feed bins need carry out the action of unloading. Then the discharge sequence of the current cycle may be bin number 1, bin number 2, bin number 4, bin number 5 and bin number 6.

In this embodiment, under the condition that there is a full bin in a plurality of bins, the unloading action can be preferentially executed to the full bin, if there is still a material and an unfinished bin after the last full bin, the unloading action can also be continuously executed to the material and the unfinished bin, and the unloading action is not executed to the empty bin, so that the unloading efficiency can be further improved by unloading more material and the unfinished bin in time as much as possible while the full bin is quickly unloaded in one cycle. Under the condition that the bins are not full in the bins, the unloading action can be executed on the bins with materials and not full, and the unloading action is not executed on the empty bins, so that the bins with materials and not full can be unloaded in time, and the condition of untimely unloading after the bins are full is avoided.

Of course, based on a preset bin priority, determining whether each bin of the multiple bins in the current cycle needs to perform a discharging action, when obtaining the first target bin and/or the second target bin, other manners may be adopted, for example, if the multiple bins have a full bin, determining the full bin with the material as the second target bin needing to perform the discharging action, and determining bins other than the second target bin as the first target bin; and when the plurality of bins are not provided with the materials and are full, determining the bins which are provided with the materials and are not full as second target bins for executing unloading actions, and determining bins outside the second target bins as first target bins.

It should be noted that the foregoing is merely illustrative of an implementation manner of determining whether each bin of the multiple bins in the current cycle needs to perform the unloading action, to obtain the first target bin that does not need to perform the unloading action and/or the second target bin that needs to perform the unloading action, and other implementation manners may also be adopted, for example, a material level state of each bin of the multiple bins in the current cycle may be determined, where the material level state includes two states of no material and no material; taking a bin without materials as a first target bin, and taking a bin with materials as a second target bin. Therefore, the material unloading operation is performed on the material bins with the materials without further distinguishing the conditions with the materials, and the empty bins are quickly skipped, so that the unloading efficiency can be improved.

In an exemplary embodiment, if the plurality of bins are provided with sequence numbers ordered along a target direction, the target direction is opposite to the running direction of the conveyor belt, and the conveyor belt is located below the discharge opening of the bin, then the second target bin in the current cycle is controlled to perform the discharge action, and a specific implementation manner thereof may include:

and sequentially controlling each second target bin to execute a discharging action along the target direction, wherein the discharging duration of each second target bin after executing the discharging action is the first duration.

And under the condition that the current second target bin is not the last second target bin, if the timing time length after the current second target bin starts to execute the unloading action reaches the second time length, controlling the next second target bin to start to execute the unloading action.

The second time length is the difference between the first time length and N times of interval time length; the interval time length is the ratio of the distance between two adjacent bins to the speed of the conveying belt; the value of N is the difference between the sequence number of the current second target bin and the sequence number of the next second target bin.

In practical application, the unloading duration of each second target bin when the second target bin executes the unloading action can be set to be the first duration T. After the second target bin is controlled to start to execute the unloading action, timing is started, and when the timing duration reaches T, the second target bin can be controlled to stop the unloading action. However, a certain distance exists between two adjacent bins, no material is arranged on the conveying belt on the certain distance, in order to improve the unloading efficiency, for the two adjacent bins, the next adjacent bin of the current bin can start to execute the unloading action in advance in the process of executing the unloading action of the current bin, and for example, when the timing time length after the current bin executes the unloading action reaches the T-interval time length T, the next adjacent bin of the current bin can be controlled to start to execute the unloading action, wherein T is the ratio of the distance between the two adjacent bins and the speed of the conveying belt, so that the area without material due to the distance between the two bins on the conveying belt can be unloaded in advance, the stacking of the material can not occur, and the unloading efficiency can be improved.

Based on this, for two adjacent second target bins, two bins which are arranged adjacently may be arranged adjacently, or two bins which are separated by another bin may be arranged adjacently, in order to improve the unloading efficiency, in the case that the current second target bin is not the last second target bin, in the process of executing the unloading action by the current second target bin, the unloading action may also be executed on the next second target bin in advance, for example, if the timing period after the current second target bin starts to execute the unloading action reaches the second period, the next second target bin is controlled to start to execute the unloading action, where the second period may be determined based on the sequence number of the current second target bin, the sequence number of the next second target bin, the first period T and the interval period T, and the second period T' is the difference between the first period and the N times of interval period, and the value of N is the sequence number N of the next second target bin ₁ With the current sequence number N of the second target bin ₂ The difference, the expression of the second duration T 'may be T' =t- (N) ₁ -N ₂ )t。

For example, among the 6 bins, the bin 1, the bin 3 and the bin 5 are full bins along the target direction, the bin 6 is an empty bin and the bin 1 is a first target bin, and then the bin 1 is controlled to start to perform the discharging action and start timing when the second target bin is controlled to perform the discharging action, the bin 3 is controlled to start to perform the discharging action and start timing when the timing time length after the bin 1 starts to perform the discharging action reaches T- (3-1) T, and the bin 3 is controlled to start to perform the discharging action when the timing time length after the bin 3 starts to perform the discharging action reaches T- (5-3) T. Thus, the present cycle ends.

In implementation, the unloading duration may be zero for the first target bin, so as to skip the first target bin.

In this embodiment, the second target bin may be opened at the present timeWhen the timing time length after the initial execution of the unloading action reaches the second time length T ', the next second target bin is controlled to start to execute the unloading action, so that the next second target bin can be unloaded in advance in the unloading process of the current second target bin, and the second time length T' is the interval time length T corresponding to the first time length T when the second target bin executes the unloading action and the distance between two adjacently arranged bins and the current sequence number N of the unloading of the second target bin ₂ And the sequence number N of the next second target bin ₁ The material can be discharged in advance in the area without the material due to the distance between the two bins on the conveying belt, so that the material stacking can not occur, and the material discharging efficiency can be improved.

In an exemplary embodiment, the unloading control method provided in this embodiment may further include:

and if the timing time length after the current second target bin starts to execute the unloading action reaches the third time length under the condition that the current second target bin is the last second target bin, controlling the first second target bin in the next cycle of the current cycle to start to execute the unloading action.

Wherein, when the sequence number of the current second target bin is larger than the sequence number of the first second target bin in the next cycle, the third time length is the sum of the first time length and M times of interval time length; and under the condition that the sequence number of the current second target bin is smaller than that of the first second target bin in the next cycle, the third time length is the difference between the first time length and the M times of interval time length.

The value of M is the absolute value of the difference between the current sequence number of the second target bin and the sequence number of the first second target bin in the next cycle.

In practical application, in the current cycle, if the current second target bin is the last second target bin, after the current second target bin is completely unloaded, the next cycle of the current cycle needs to be entered, and the next cycle needs to execute the sequence number N of the first second target bin of the unloading action ₃ Possibly greater than the current second target bin sequence number N ₂ It is also possible toA sequence number N smaller than the current second target bin ₂ 。

Sequence number N of second target bin at present ₂ Sequence number N greater than the first and second target bins in the next cycle ₃ If the timing time length after the current second target bin starts to execute the unloading action reaches the third time length T ', controlling the first second target bin to start to execute the unloading action in the next cycle of the current cycle, wherein the third time length T' is the sum of the first time length T and M times of the interval time length, and the value of M is the sequence number N of the current second target bin ₂ Sequence number N of first and second target bin in next cycle ₃ The absolute value of the difference, the third time period T ", is denoted T" =t+|n ₂ -N ₃ And t. Therefore, after the current second target bin finishes the discharging action, the first second target bin in the next cycle of the current cycle is controlled to start to execute the discharging action after the time delay of M times of interval duration, and the phenomenon that the current second target bin is overlapped when the discharging area reaches the first second target bin in the next cycle along with the conveying belt can be avoided.

Sequence number N of second target bin at present ₂ A sequence number N smaller than the first and second target bins in the next cycle ₃ If the timing time length after the current second target bin starts to execute the unloading action reaches a third time length T ", controlling the first second target bin in the next cycle of the current cycle to start to execute the unloading action, wherein the third time length T" is the difference between the first time length T and the M times of interval time length, and the third time length T "is expressed as T" =t- |n ₂ -N ₃ |t。
