Description

Technical Field

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

[0002] Casting is a process of melting metal materials into liquid, pouring them into prefabricated molds, cooling and solidifying them to form workpieces of specific shapes. When casting larger volume materials, the molds usually use sand cores with good air exhaust and yield properties. During the casting process, it is necessary to first make the shape of the sand core in the upper and lower boxes, and then apply paint and surface drying treatment to fix the sand core in the box. After that, the upper and lower boxes can be combined and installed to complete the mold making.

[0003] In order to improve production efficiency, the automated assembly line manufacturing method is now mostly used to produce castings, and each step is completed by automated equipment. However, since the time interval between the production and processing of sand cores and the material processing line before the production line is relatively long, and the material processing speed of subsequent production line processing (such as box assembly, casting, etc.) is relatively fast, a single sand core production and processing line before the production line is difficult to meet the feeding needs of subsequent production lines. Therefore, multiple sand core production and processing lines before the production line are usually set up to carry out production work together to ensure the processing efficiency of subsequent production lines.

[0004] In the subsequent processing of the assembly line, the feeding rhythm of the material into the subsequent workstation needs to meet the needs of the workstation. Figure 1 Taking the state shown as an example, the feeding line 1 is divided according to the feeding rhythm so that the time interval for each forward grid of the feeding line 1 is the same, and each material needs to be placed in the divided independent grid, so that the normal processing function can be guaranteed when entering the subsequent processing station. For example, in the box closing step, it is necessary to ensure that only one box is in the accurate position of the station 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 guaranteed.

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

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

[0007] The present invention provides an automated casting line intelligent feeding control system, comprising: Feeding line, used for material feeding; Multiple feeding components for transporting materials produced by the previous production line; Each feeding assembly includes a feeding section, a buffer section and an adjustment section arranged in sequence along the direction from the feeding line to the front production line; one end of all the feeding sections is connected to one end of the feeding line; one end of all the adjustment sections is respectively connected to a corresponding front production line; and also includes: A collecting section, arranged on the side of the sending section; A commutator is provided between the delivery section and the buffer section, and is used to switch the connection state of the delivery section, the buffer section and the collection section; A first trigger is arranged at one end of the adjustment section close to the front production line; The calculation module is used to collect the information of all the first triggers and store the control model for controlling the operation of each component in the feeding assembly.

[0008] Furthermore, the length of the buffer section is greater than that of the delivery section and the adjustment section.

[0009] Furthermore, each feeding assembly also includes: A second trigger is arranged at one end of the adjustment section close to the buffer section; The third trigger is arranged at one end of the buffer section close to the delivery section.

[0010] Furthermore, a guide plate is provided at the delivery section to guide the material to move to the center of the delivery section in the width direction.

[0011] The present invention also provides an automated casting line intelligent feeding control method, using the automated casting line intelligent feeding control system, comprising: Basic settings: Assume that the feeding interval on the feeding line is Tfee, and the production interval of the previous production line is Tpro; calculate Tpro / Tfee and round it up to get the basic multiple n0; Startup phase: when the first trigger in any feeding component is activated, the corresponding feeding component is switched from standby state to active state; the number of feeding components in active state is recorded as n; the control model controls the transportation time of the delivery section, buffer section and adjustment section by inputting the values ​​of n and n0; Adjustment phase: When any feeding component switches to the standby state, the transportation time of the feeding section, buffer section and adjustment section is updated through the control model.

[0012] Furthermore, the use phase also includes: Set the judgment time T0; For each feeding component in the activated state, the corresponding first trigger will record the time T from 0 after detecting the material, and each time the first trigger detects the material, T will be reset to zero; When the T corresponding to a feeding component reaches the T0 value, the feeding component is switched to the standby state.

[0013] Furthermore, the control model is specifically: The time it takes for the material to move from one end of the delivery section to the other end is recorded as Ta; The time it takes for the material to move from one end of the buffer section to the other end is recorded as Tb; The time it takes for the material to move from one end of the adjustment section to the other end is recorded as Tc; Startup phase: the first feeding component switched to the activated state is numbered as 1, and the time t is recorded from 0. After that, each time the first trigger of the feeding component detects the material, t is reset to zero; the delivery section, buffer section and adjustment section of the feeding component are operated in the set states of Ta1, Tb1 and Tc1 respectively; Afterwards, the qth feeding component switched to the active state is numbered as q, and the value of t at this time is recorded as tq; Tcq=Tc1+q·T0-tq is calculated; and the value of n at this time is updated; If n≤n0, the delivery section, buffer section and adjustment section of the feeding assembly are operated in the states of Ta1, Tb1 and Tcq respectively; If n>n0, then calculate Taq=Ta1·(n-1) / n, Tbq=Tb1·n / (n-1), and operate the delivery section, buffer section and adjustment section of the feeding component in the states of Taq, Tbq and Tcq respectively, and adjust the delivery section and buffer section of other active feeding components to operate in the states of Taq and Tbq respectively; Each time a feeding component is switched to an activated state, the value with the largest number of materials on the buffer section among all activated feeding components is recorded as Ymax, and all feeding components are switched to connect the collecting section with the buffer section until the collecting section where Ymax is located passes Ymax materials, and then all feeding components are switched to connect the sending section with the buffer section.

[0014] Furthermore, the control model also includes: Adjustment stage: when a feeding component switches from an active state to a standby state, the number of feeding components in the active state before the switch is recorded as C; If C≤n0, the numbers of other feeding components in the active state are maintained, and the number D of the feeding component switched to the standby state is recorded; when a new feeding component is switched to the active state, the feeding component is regarded as the Dth feeding component switched to the active state to calculate the operation status of its delivery section, buffer section and adjustment section; If C>n0, all other active feeding components are renumbered according to the number size, and the operating status of their feeding section, buffer section and adjustment section are updated and calculated.

[0015] Furthermore, a second trigger is 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; In the basic setting, the corresponding adjustment section material quantity is set to Y for each feeding component, and the initial value is 0; When the second trigger of the feeding component detects the material, the corresponding Y value is increased by one; When the third trigger of the feeding component detects the material, the corresponding Y value is reduced by one.

[0016] Furthermore, the Tc value is controlled so that the number of materials on the adjustment section is at most one.

The present invention realizes full-automatic control of the feeding process through a computing module and multiple triggers. Through the coordination of the feeding section, the buffer section and the adjustment section, the arrangement interval of the materials can be accurately controlled to ensure that the distribution of the materials on the feeding line meets the requirements of the subsequent workstations, reducing the need for manual intervention and significantly improving the automation level of the production line.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present invention relates to an intelligent feeding control system for an automated casting production line. Figure 2 As shown, including: Loading line 1 is used to load materials into the subsequent stations of the assembly line; Multiple feeding components 3 are used to transport materials produced by the front production line 2 and to arrange the materials on the feeding line 1 into intervals that meet the feeding requirements of subsequent workstations; the feeding components 3 have two states: a standby state and an active state. The standby state means that the front production line 2 corresponding to the feeding component 3 has not started to produce materials at this time, and the active state means that the front production line 2 corresponding to the feeding component 3 is producing materials at this time; Each feeding assembly 3 includes a feeding section 3a, a buffer section 3b and an adjustment section 3c which are sequentially arranged along the direction from the feeding line 1 to the front production line 2; one end of each feeding section 3a is connected to one end of the feeding line 1; one end of each adjustment section 3c is respectively connected to a corresponding front production line 2; and further includes: The collecting section 3d is arranged on the side of the sending section 3a; The commutator 3e is arranged between the delivery section 3a and the buffer section 3b, and is used to switch the connection state of the delivery section 3a, the buffer section 3b and the collection section 3d, so that the delivery section 3a is connected to the buffer section 3b, or the collection section 3d is connected to the buffer section 3b; The first trigger 3f is arranged at one end of the adjustment section 3c close to the front production line 2. The first trigger 3f can be a proximity switch or a laser rangefinder. When the material approaches the first trigger 3f, the first trigger 3f will send a signal. The calculation module is used to collect the information of all the first triggers 3f and store the control model for controlling the operation of each component in the feeding assembly 3.

[0026] The feeding control system replaces the traditional single conveyor line by using the feeding component 3 with a combination of a delivery section 3a, a buffer section 3b and an adjustment section 3c. The feeding speed of each section can be adjusted separately, and all adjustments are automatically completed through the cooperation of the calculation module and the first trigger 3f, so that the feeding control system can perform feeding control according to the activation state of each feeding component 3, ensuring that each feeding component 3 can form an arrangement state that meets the requirements after reaching the loading line 1. The delivery section 3a, the buffer section 3b and the adjustment section 3c can be realized using existing transmission equipment, and their lengths, layouts, etc. can be adjusted accordingly according to the use site conditions, so that the cost of the feeding control system is lower and the adaptability is wider. The feeding control system is also designed with 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, thereby ensuring the accurate arrangement of the materials on the loading line 1. The number of materials removed is usually small, and can be manually placed on the loading line 1 later.

[0027] It is preferred that the length of the buffer section 3b is greater than the delivery 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.

[0028] Preferably, each feeding assembly 3 also includes: A second trigger 3g is arranged at one end of the adjustment section 3c close to the buffer section 3b; The third trigger 3h is arranged at one end of the buffer section 3b close to the delivery section 3a.

[0029] Through the cooperation of the second trigger 3g and the third trigger 3h, the amount of material on the buffer section 3b can be calculated.

[0030] Preferably, a guide plate is provided on the delivery section 3a to guide the material to move to the center of the delivery section 3a in the width direction.

[0031] The present invention also relates to an intelligent feeding control method for an automated casting assembly line, using the intelligent feeding control system for an automated casting assembly line as described above, comprising: Basic settings: Assume that the feeding interval of feeding line 1 is Tfee, and the production interval of front production line 2 is Tpro; calculate Tpro / Tfee and round up to get the basic multiple n0. For example, if the feeding interval of feeding line 1 is 2s, and the production interval of front production line 2 is 9s, then 9 / 2=4.5, and round up to get the basic multiple n0=5; 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 feeding component 3 is activated, the corresponding feeding component 3 is switched from the standby state to the active state. The number of feeding components 3 in the active state is recorded as n. The control model controls the transportation time of the delivery section 3a, the buffer section 3b and the adjustment section 3c by inputting the values ​​of n and n0. Adjustment phase: This phase is mainly a control phase when, during the transportation process of the feeding system, some front production lines 2 are shut down due to maintenance or other operations. When any feeding component 3 switches to the standby state, the transportation time of the delivery section 3a, the buffer section 3b and the adjustment section 3c are updated through the control model.

[0032] This method calculates the basic multiple n0, and according to the activation state of the previous production line (the change of n value), the control model can flexibly adjust the feeding speed of each section to ensure that each feeding component can meet the needs of the loading line under different conditions, thereby avoiding material accumulation or material breakage. The operations of the delivery section 3a, buffer section 3b and adjustment section 3c in the feeding system are all automatically completed through the calculation module and trigger, reducing the need for manual intervention and improving the automation level of the production line. Through the coordination between the delivery section 3a, buffer section 3b and adjustment section 3c, the arrangement of materials can be accurately controlled to ensure that the materials on the loading line 1 are transported at intervals that meet the requirements, thereby improving production efficiency and product quality. When individual front production lines 2 need to be shut down, this method can adjust the feeding speed in time to adapt to changes in production equipment and ensure the continuity and stability of the entire production line.

[0033] The standby state and the active state of the feeding component 3 can be switched manually, or can be switched automatically during the use phase by the following method: Set the judgment time T0, which is usually slightly longer than the production interval of the previous production line 2; For each feeding component 3 in an activated state, the corresponding first trigger 3f will start recording time T from 0 after detecting the material, and each time the first trigger 3f detects the material, T will be reset to zero; When the T corresponding to a feeding component 3 reaches the T0 value, it means that no new material has been produced from the previous production line 2 after the T0 time has passed. At this time, it is very likely that the previous production line 2 has automatically stopped due to a malfunction or other reasons, and the feeding component 3 is switched to standby mode.

[0034] This automatic switching method can ensure that the feeding component 3 can detect and automatically switch the state as soon as the front production line 2 stops, so that the feeding control system can quickly adjust the state to ensure that the material distribution on the loading line 1 meets the requirements.

[0035] The speed of each section of the feeding assembly 3 is mainly controlled by the calculation of the control model, and the control model is specifically: First, the time for the material to move from one end of the delivery section 3a to the other end is set as Ta; The time for the material to move from one end of the buffer section 3b to the other end is recorded as Tb; The time it takes for the material to move from one end of the adjustment section 3c to the other end is recorded as Tc; Ta of each feeding assembly 3 can be calculated and controlled by Ta=Va / La, where Va is the feeding speed of the feeding section 3a, which is the value that the conveyor belt motor can directly control; 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.

[0036] Startup phase: the first feeding component 3 switched to the activated state is numbered as 1, and the time t is recorded from 0. After that, each time the first trigger 3f of the feeding component 3 detects the material, t is reset to zero; the delivery section 3a, buffer section 3b and adjustment section 3c of the feeding component 3 are operated in the set states of Ta1, Tb1 and Tc1 respectively; preferably, Ta1, Tb1 and Tc1 need to satisfy: Ta1+Tb1+Tc1=X·T0, where X is a set integer, so that the time for the material to pass through the feeding component 3 can match the feeding interval of the feeding line 1, ensuring that the material falls exactly at the center of the demand grid of 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 T0s between the materials on the feeding line 1.

[0037] Afterwards, the qth feeding component 3 switched to the activated state is numbered as q, and the value of t at this time is recorded as tq; Tcq=Tc1+q·T0-tq is calculated, and the speed of the adjustment section 3c of the feeding component 3 is calculated by this formula, so that the material of the qth numbered feeding component 3 is exactly q·T0 slower when it is transported to the end of the adjustment section 3c than the material of the 1st numbered feeding component 3 is when it is transported to the end of the adjustment section 3c; then the value of n at this time is updated.

[0038] If n≤n0, it means that the intervals between the materials of feeding line 1 have not been completely filled. For example, if the material of feeding component 3 No. 1 is recorded as "1", the material of feeding component 3 No. 2 is recorded as "2"... Then on feeding line 1, when n=1, the material arrangement is "1, 1, 1...", and there will be n0 T0s between the materials; 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; When n=3, the "3" material can be inserted between the intervals 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; Similarly, when n≤n0, it means that there is still a gap between the materials "n" and "n-1" that can be inserted, and at this time, the materials of the q-feeding assembly 3 can be filled into the aforementioned gap. The delivery section 3a, buffer section 3b and adjustment section 3c of the q-feeding assembly 3 operate in the states of Ta1, Tb1 and Tcq respectively.

[0039] If n>n0, it means that there is no space for inserting materials between the materials of 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 delivery 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 delivery section 3a and buffer section 3b of other activated feeding components 3 to operate in the states of Taq and Tbq respectively, so that the feeding speeds of all feeding components 3 are reduced synchronously, thereby leaving a gap for the subsequent materials to be inserted on the feeding line 1.

[0040] Each time a feeding component 3 is switched to an activated state, the value with the largest amount of materials on the buffer segment 3b among all the activated feeding components 3 is recorded as Ymax, and all feeding components 3 are switched to the collecting segment 3d connected to the buffer segment 3b, until the collecting segment 3d where Ymax is located passes Ymax materials, and then all feeding components 3 are switched to the sending segment 3a connected to the buffer segment 3b, so that the materials that cannot meet the new feeding needs are removed from the feeding components 3.

[0041] The control model also includes: Adjustment stage: when a feeding component 3 switches from an active state to a standby state, the number of the feeding components 3 in the active state before the switching is recorded as C; If C≤n0, the numbers of other feeding components 3 in the active state are maintained, and the number D of the feeding component 3 switched to the standby state is recorded; when a new feeding component 3 is switched to the active state later, the feeding component 3 is taken as the Dth feeding component 3 switched to the active state to calculate the operation status of its delivery section 3a, buffer section 3b and adjustment section 3c. For example, if feeding component 2 of feeding components 3 No. 1 to 4 is switched to the standby state, then at this time, since the conveying speed of the delivery section 3a and the buffer section 3b has not changed, it is only necessary to let the newly connected feeding component 3 replace the position of feeding component 2.

[0042] If C>n0, all other active feeding components 3 are renumbered according to the number size, and the operation status of their delivery section 3a, buffer section 3b and adjustment section 3c are updated and calculated. For example, if the No. 2 feeding component 3 among the No. 1 to 7 feeding components 3 is switched to the standby state, since the number of active feeding components 3 changes each time, the operation status of the delivery section 3a, buffer section 3b and adjustment section 3c needs to be recalculated, so the remaining 6 feeding components 3 must be renumbered according to 1 to 6, and then Ta6, Tb6 and Tc6 are updated and calculated, and the delivery section 3a, buffer section 3b and adjustment section 3c of each feeding component 3 are adjusted to the corresponding operation status.

[0043] The amount of material on the buffer section 3b can be recorded by the following method: a second trigger 3g is set at one end of the adjustment section 3c close to the buffer section 3b, and a third trigger 3h is set at one end of the buffer section 3b close to the delivery section 3a; In the basic setting, the material quantity of the corresponding adjustment section 3c of each feeding component 3 is set to Y, and the initial value is 0; When the second trigger 3g of the feeding component 3 detects the material, the corresponding Y value is increased by one; When the third trigger 3h of the feeding component 3 detects the material, the corresponding Y value is reduced by one.

[0044] In this method, the Tc value is preferably controlled so that the number of materials on the adjustment section 3c is at most one, ensuring that the materials will 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.
