Description

Technical Field

[0001] The present invention relates to the technical field of automated production lines, and particularly to an intelligent feeding control system and method for an automated casting production line. Background Art

[0002] Casting is a process of melting metal materials into a liquid, pouring them into prefabricated molds, and cooling and solidifying them to form workpieces with specific shapes. For larger-volume materials during casting, the molds usually use sand cores with better exhaustibility and collapsibility. During the casting process, it is necessary to first make the shape of the sand core in the upper and lower boxes, and then through coating, surface drying treatment, etc., to make the sand core fixed in the box. After that, the upper and lower boxes can be assembled to complete the production of the mold.

[0003] In order to improve production efficiency, the current production of castings mostly adopts the manufacturing method of an automated production line, and each step is completed by automated equipment. However, due to the relatively long time interval of the production line materials before the production and processing of the sand core, while the material processing speed of the subsequent production line processing (such as steps like closing the box and casting) is relatively fast, it is difficult for a single sand core production and processing production line in front to meet the feeding requirements of the subsequent production line. Therefore, usually multiple sand core production and processing production lines in front are set up to carry out production work together to ensure the processing efficiency of the subsequent production line.

[0004] During the processing of the subsequent production line, it is necessary to make the feeding rhythm of the materials entering the subsequent workstations meet the requirements of the workstations. Taking the Figure 1 shown state as an example, the feeding line 1 is divided according to the feeding rhythm, so that the time interval for the feeding line 1 to move forward one grid is the same, and the placement position of each material needs to be in the independent grids divided. Only in this way can the normal processing function be ensured when entering the subsequent processing workstations. For example, in the step of closing the box, it is necessary to ensure that only one box is in the accurate position of the workstation when closing the box; the interval between adjacent boxes cannot be too large, so as to ensure that the working interval will not be too long and the processing efficiency can be ensured.

[0005] Since there are now multiple front production lines 2 (i.e., sand core production and processing production lines) producing materials simultaneously, it is necessary to arrange the materials produced by multiple front production lines 2 in each grid of the feeding line 1. In the existing related technologies, usually, the materials produced by each front production line 2 are first collected, and then the materials are placed on the feeding line 1 through special equipment. This method not only has many steps and low efficiency, but also has a high equipment cost. Summary of the Invention

[0006] The present invention provides an intelligent feeding control system and method for an automated casting production line, which can effectively solve the problems of low efficiency and high cost of the existing feeding methods.

[0017] A second trigger arranged at one end of the adjustment section close to the buffer section;

[0018] A third trigger arranged at one end of the buffer section close to the sending section.

[0019] Further, a guide plate is arranged on the sending section for guiding the material to move to the center of the width direction of the sending section.

[0020] The present invention also provides an intelligent feeding control method for an automated casting production line, using the above-mentioned intelligent feeding control system for an automated casting production line, including:

[0021] Basic setting: Set the loading interval on the loading line as Tfee, and the production interval of the previous production line as Tpro; calculate Tpro / Tfee and round up to obtain the basic multiple n0;

[0022] Startup stage: When any first trigger in a feeding component is activated, switch the corresponding feeding component from the standby state to the activated state; record the number of feeding components in the activated state as n; the control model controls the transportation time of the sending section, the buffer section, and the adjustment section by inputting the values of n and n0.

[0023] Adjustment stage: When any one of the feeding components switches to the standby state, the transportation times of the feeding section, the buffer section, and the adjustment section are updated through the control model.

[0024] Furthermore, the usage stage also includes:

[0025] Set the judgment duration T0;

[0026] For each feeding component in the active state, the corresponding first trigger starts recording the time T from 0 when it detects the material, and each time the first trigger detects the material, T is cleared;

[0027] When the T corresponding to a feeding component reaches the value of T0, that feeding component is switched to the standby state.

[0028] Furthermore, the control model is specifically:

[0029] Record the time for the material to move from one end of the feeding section to the other end as Ta;

[0030] Record the time for the material to move from one end of the buffer section to the other end as Tb;

[0031] Record the time for the material to move from one end of the adjustment section to the other end as Tc;

[0032] Startup stage: Number the first feeding component switched to the active state as 1, and start recording the time t from 0. After that, each time the first trigger of this feeding component detects the material, t is cleared; operate the feeding section, the buffer section, and the adjustment section of this feeding component in the set states of Ta1, Tb1, and Tc1 respectively;

[0033] After that, number the qth feeding component switched to the active state as q, and record the value of t at this time as tq; calculate Tcq = Tc1 + q·T0 - tq; then update the value of n at this time;

[0034] If n ≤ n0, operate the feeding section, the buffer section, and the adjustment section of this feeding component in the states of Ta1, Tb1, and Tcq respectively;

[0035] If n > n0, calculate Taq = Ta1·(n - 1) / n, Tbq = Tb1·n / (n - 1), operate the feeding section, the buffer section, and the adjustment section of this feeding component in the states of Taq, Tbq, and Tcq respectively, and adjust the feeding section and the buffer section of other active feeding components to operate in the states of Taq and Tbq respectively;

[0036] Each time a feeding component switches to the active state, record the maximum value of the number of materials on the buffer section among all the active feeding components as Ymax. Connect all the feeding components to the collection section and the buffer section until the collection section where Ymax is located has passed Ymax materials, and then connect all the feeding components to the delivery section and the buffer section.

[0037] Further, the control model further includes:

[0038] Adjustment stage: When a feeding component switches from the active state to the standby state, record the number of active feeding components before the switch as C;

[0039] If C ≤ n0, maintain the numbers of other active feeding components and record the number D of the feeding component that switches to the standby state; when a new feeding component switches to the active state subsequently, use this feeding component as the D-th feeding component to switch to the active state and calculate the operating states of its delivery section, buffer section, and adjustment section;

[0040] If C > n0, re-number all other active feeding components according to their numbers and update and calculate the operating states of their delivery sections, buffer sections, and adjustment sections.

[0041] Further, a second trigger is also provided at one end of the adjustment section close to the buffer section, and a third trigger is provided at one end of the buffer section close to the delivery section;

[0042] During basic setting, set the corresponding buffer section material quantity for each feeding component as Y, with an initial value of 0;

[0043] When the second trigger of this feeding component detects a material, the corresponding Y value is incremented by one;

[0044] When the third trigger of this feeding component detects a material, the corresponding Y value is decremented by one.

[0045] Further, control the Tc value so that there is at most one material quantity on the adjustment section.

[0046] Through the technical solution of the present invention, the following technical effects can be achieved:

[0056] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The present invention relates to an intelligent feeding control system for an automated casting production line, as Figure 2 shown, including:

[0058] A loading line 1 for loading materials into subsequent workstations of the production line;

[0059] A plurality of feeding components 3 for transporting the materials produced by the previous production line 2 and enabling the materials to be arranged at intervals on the loading line 1 that meet the feeding requirements of subsequent workstations. The feeding component 3 has two states: a standby state and an activated state. The standby state means that the corresponding previous production line 2 of this feeding component 3 has not started producing materials yet, and the activated state means that the corresponding previous production line 2 of this feeding component 3 is producing materials at this time;

[0060] Each feeding component 3 includes a feeding section 3a, a buffer section 3b, and an adjustment section 3c arranged in sequence along the direction from the loading line 1 to the previous production line 2; one ends of all the feeding sections 3a are connected to one end of the loading line 1; one ends of all the adjustment sections 3c are respectively connected to a corresponding previous production line 2; and it further includes:

[0061] A collection section 3d arranged on the side of the feeding section 3a;

[0062] A commutator 3e arranged between the feeding section 3a and the buffer section 3b for switching the connection states of the feeding section 3a, the buffer section 3b, and the collection section 3d to connect the feeding section 3a to the buffer section 3b or the collection section 3d to the buffer section 3b;

[0063] A first trigger 3f arranged at one end of the adjustment section 3c close to the previous production line 2. The first trigger 3f can be a proximity switch or a laser rangefinder, etc. When the material approaches the first trigger 3f, the first trigger 3f will emit a signal;

[0064] A calculation module for collecting the information of all the first triggers 3f and storing a control model for controlling the operation of each component in the feeding component 3.

[0065] This feeding control system replaces the traditional single conveyor line by combining the feeding component 3 with a feeding section 3a, a buffer section 3b, and an adjustment section 3c. The feeding speeds of each section can be adjusted independently, and all adjustments are automatically completed through the cooperation of the calculation module and the first trigger 3f. Thus, this feeding control system can perform feeding control according to the activation status of each feeding component 3, ensuring that each feeding component 3 can form a layout that meets the requirements after reaching the loading line 1. The feeding section 3a, the buffer section 3b, and the adjustment section 3c can be realized by using existing transmission equipment, and their lengths, arrangement methods, etc. can be correspondingly adjusted according to the on-site situation, so that this feeding control system has lower cost and wider adaptability. This feeding control system also designs a collection section 3d and a commutator 3e. When the state of the feeding component 3 is switched, the materials that cannot meet the new feeding requirements can be removed from the feeding component 3 through the collection section 3d, thus ensuring the accurate layout of the materials on the loading line 1. The number of materials removed is usually not large and can be manually placed on the loading line 1 later.

[0066] Preferably, the length of the buffer section 3b is greater than that of the feeding section 3a and the adjustment section 3c. The longer buffer section 3b can provide sufficient time for the calculation of the calculation module and the adjustment of the feeding component 3.

[0067] Preferably, each feeding component 3 further includes:

[0068] A second trigger 3g, arranged at one end of the adjustment section 3c close to the buffer section 3b;

[0069] A third trigger 3h, arranged at one end of the buffer section 3b close to the feeding section 3a.

[0070] Through the cooperation of the second trigger 3g and the third trigger 3h, the number of materials on the buffer section 3b can be calculated.

[0071] Preferably, a guide plate is arranged on the feeding section 3a for guiding the materials to the center of the width direction of the feeding section 3a.

[0072] The present invention also relates to an intelligent feeding control method for an automated casting production line, using the intelligent feeding control system for an automated casting production line as described above, including:

[0073] Basic setting: Set the loading interval of the loading line 1 as Tfee, and the production interval of the front production line 2 as Tpro; calculate Tpro / Tfee and round up to obtain the basic multiple n0. For example, if the loading interval of the loading line 1 is 2s and the production interval of the front production line 2 is 9s, then 9 / 2 = 4.5, and the basic multiple n0 = 5 is obtained after rounding up;

[0074] Startup phase: This phase is mainly the control phase when the front production line 2 is turned on in sequence. When the first trigger 3f in any one of the feeding components 3 is activated, the corresponding feeding component 3 is switched from the standby state to the activated state; let the number of feeding components 3 in the activated state be n; the control model controls the transportation times of the feeding section 3a, the buffer section 3b, and the adjustment section 3c by inputting the values of n and n0.

[0075] Adjustment phase: This phase is mainly the control phase when individual front production lines 2 are under maintenance or other operations during the transportation process of the feeding system, resulting in the shutdown of the front production line 2. When any one of the feeding components 3 is switched to the standby state, the control model updates the transportation times of the feeding section 3a, the buffer section 3b, and the adjustment section 3c.

[0076] This method calculates the basic multiple n0, and based on the activation state of the front production line (the change in the value of n), the control model can flexibly adjust the feeding speeds of each section to ensure that each feeding component can meet the requirements of the feeding line in different states, thereby avoiding material accumulation or material shortage. All operations of the feeding section 3a, the buffer section 3b, and the adjustment section 3c in the feeding system are automatically completed by the calculation module and the trigger, reducing the need for manual intervention and improving the automation level of the production line. Through the coordination between the feeding section 3a, the buffer section 3b, and the adjustment section 3c, the arrangement of materials can be precisely controlled to ensure that the materials on the feeding line 1 are transported at intervals that meet the requirements, improving production efficiency and product quality. When an individual front production line 2 needs to be shut down, this method can timely adjust the feeding speed to adapt to the changes in production equipment and ensure the continuity and stability of the entire production line.

[0077] The standby state and the activated state of the feeding component 3 can be switched manually or automatically through the following method during the use phase:

[0078] Set the judgment duration T0, and T0 is usually slightly longer than the production interval of the front production line 2.

[0079] For each feeding component 3 in the activated state, the corresponding first trigger 3f starts recording the time T from 0 after detecting the material, and each time the first trigger 3f detects the material, T is cleared.

[0080] When the T corresponding to a feeding component 3 reaches the value of T0, it means that no new material has been produced from the front production line 2 after a time of T0. At this time, it is very likely that the front production line 2 has automatically stopped due to a fault or other reasons, and then this feeding component 3 is switched to the standby state.

[0081] This automatic switching method can ensure that the feeding component 3 can detect and automatically switch its state immediately when the front production line 2 stops, so that the feeding control system can quickly adjust its state and ensure that the material distribution on the feeding line 1 meets the requirements.

[0082] The rotation speed of each section of the feeding component 3 is mainly controlled by the calculation of the control model. The specific control model is as follows:

[0083] First, set the time for the material to move from one end to the other end of the feeding section 3a as Ta;

[0084] Set the time for the material to move from one end to the other end of the buffer section 3b as Tb;

[0085] Set the time for the material to move from one end to the other end of the adjustment section 3c as Tc;

[0086] The Ta of each feeding component 3 can be calculated and controlled by Ta = Va / La, where Va is the feeding speed of the feeding section 3a, which is a value that can be directly controlled by the conveyor belt motor; La is the length of the feeding section 3a, and after the feeding section 3a is set up, La is a fixed value. Similarly, Tb and Tc can also be calculated and controlled by the same method.

[0087] Startup stage: Number the first feeding component 3 switched to the active state as 1, and record the time t starting from 0. After that, every time the first trigger 3f of this feeding component 3 detects the material, clear t; operate the feeding section 3a, buffer section 3b, and adjustment section 3c of this feeding component 3 in the set states of Ta1, Tb1, and Tc1 respectively; preferably, Ta1, Tb1, and Tc1 should satisfy: Ta1 + Tb1 + Tc1 = X·T0, where X is a set integer. In this way, the time for the material to pass through the feeding component 3 can be matched with the feeding interval of the feeding line 1, ensuring that the material just falls at the center of the required grid on the feeding line 1 after passing through the feeding component 3. At this time, only one front production line 2 is producing materials, so there will be n0 T0 intervals between the materials on the feeding line 1.

[0088] After that, number the qth feeding component 3 switched to the active state as q, and record the value of t at this time as tq; calculate Tcq = Tc1 + q·T0 - tq, and calculate the speed of the adjustment section 3c of this feeding component 3 through this formula, so that the material of the qth numbered feeding component 3 is exactly q·T0 slower than the material of the first numbered feeding component 3 when it reaches the end of the adjustment section 3c; then update the n value at this time.

[0089] If n ≤ n0, it indicates that the intervals between the materials on the feeding line 1 have not been fully filled. For example, if the material of the No. 1 feeding component 3 is denoted as "1", the material of the No. 2 feeding component 3 is denoted as "2"...

[0090] Then on the feeding line 1, when n = 1, the material arrangement is "1, 1, 1...", and at this time, there will be n0 T0 intervals between the materials;

[0091] When n = 2, the "2" material can be inserted between two "1" materials, and the material arrangement is "1, 2, 1, 2...". The interval from "1" to "2" is T0, and the interval from "2" to "1" is n0 - 1 T0;

[0092] When n = 3, the "3" material can be inserted into the interval from "2" to "1", and the material arrangement is "1, 2, 3, 1, 2, 3...". The intervals from "1" to "2" and from "2" to "3" are both T0, and the interval from "3" to "2" is n0 - 2 T0;

[0093] And so on. When n ≤ n0, it indicates that there is still an insertable interval between the "n" and "n - 1" materials. At this time, the material of the qth feeding component 3 can be filled into the aforementioned interval. The sending section 3a, buffer section 3b, and adjustment section 3c of the qth feeding component 3 operate in the states of Ta1, Tb1, and Tcq respectively.

[0094] If n > n0, it indicates that there is no interval available for insertion between the materials on the feeding line 1. At this time, it is necessary to adjust the speed of the feeding component 3. Calculate Taq = Ta1·(n - 1) / n, Tbq = Tb1·n / (n - 1), and operate the sending section 3a, buffer section 3b, and adjustment section 3c of the feeding component 3 in the states of Taq, Tbq, and Tcq respectively. And adjust the sending section 3a and buffer section 3b of other activated feeding components 3 to operate in the states of Taq and Tbq respectively, so as to synchronously reduce the feeding speed of all feeding components 3, thereby leaving an insertable interval for the subsequent materials on the feeding line 1.

[0095] Each time a feeding component 3 is switched to the activated state, record the maximum value of the number of materials on the buffer section 3b among all the activated feeding components 3 as Ymax. Connect the collection section 3d of all feeding components 3 to the buffer section 3b. Until the collection section 3d where Ymax is located passes through Ymax materials, then switch all feeding components 3 to connect the sending section 3a to the buffer section 3b, so as to remove the materials that cannot meet the new feeding requirements from the feeding component 3.

[0096] The control model further includes:

[0097] Adjustment stage: When a feeding component 3 switches from the active state to the standby state, record the number of feeding components 3 in the active state before the switch as C;

[0098] If C ≤ n0, maintain the numbers of the other feeding components 3 in the active state and record the number D of the feeding component 3 that switches to the standby state; when a new feeding component 3 switches to the active state subsequently, use this feeding component 3 as the Dth feeding component 3 that switches to the active state to calculate the operating states of its feeding section 3a, buffer section 3b, and adjustment section 3c. For example, if the No. 2 feeding component 3 among the feeding components 3 numbered 1 to 4 switches to the standby state, then at this time, since the conveying speeds of the feeding section 3a and the buffer section 3b do not change, it is only necessary to let the newly connected feeding component 3 replace the position of the No. 2 feeding component.

[0099] If C > n0, re-number all the other feeding components 3 in the active state according to their numbers and update the calculation of the operating states of their feeding sections 3a, buffer sections 3b, and adjustment sections 3c. For example, if the No. 2 feeding component 3 among the feeding components 3 numbered 1 to 7 switches to the standby state, since the number of feeding components 3 in the active state changes each time and the operating states of the feeding section 3a, buffer section 3b, and adjustment section 3c need to be recalculated, the remaining 6 feeding components 3 must be re-numbered from 1 to 6, and then Ta6, Tb6, and Tc6 are calculated and updated, and the feeding sections 3a, buffer sections 3b, and adjustment sections 3c of each feeding component 3 are adjusted to the corresponding operating states.

[0100] The quantity of materials on the buffer section 3b can be recorded by the following method: Set a second trigger 3g at one end of the adjustment section 3c close to the buffer section 3b, and set a third trigger 3h at one end of the buffer section 3b close to the feeding section 3a;

[0101] In the basic setting, set the corresponding quantity of materials on the buffer section 3b for each feeding component 3 as Y, and the initial value is 0;

[0102] When the second trigger 3g of this feeding component 3 detects materials, the corresponding Y value is incremented by one;

[0103] When the third trigger 3h of this feeding component 3 detects materials, the corresponding Y value is decremented by one.

[0104] In this method, preferably control the Tc value so that there is at most one material quantity on the adjustment section 3c to ensure that materials do not accumulate on the adjustment section 3c, thereby accurately ensuring the time for the materials of each feeding component 3 to move to the end of the adjustment section 3c.
