Description

Technical Field

[0001] This invention relates to the field of electrical control technology for tobacco processing line equipment, and in particular to a method, device, equipment, medium, and product for controlling a material buffer cabinet fabric trolley. Background Technology

[0002] According to tobacco processing requirements, material buffer cabinets are installed at the feeding ends of key processes such as leaf moistening and feeding, leaf expansion and drying, and tobacco flavoring. Their function is to continuously and uniformly store materials on the production line at a certain stacking height and to uniformly and continuously discharge them at a certain discharge speed, ensuring the uniformity and smoothness of materials at subsequent key processing points. A material distribution trolley is installed above the buffer cabinet. Through its back-and-forth movement, the material distribution trolley ensures that the production line materials are continuously and uniformly distributed within the buffer cabinet at a certain stacking height.

[0003] There are two main types of material placement methods for existing trolleys: stepping and reciprocating. Stepping placement uses two pairs of photoelectric sensors installed at the front and rear ends of the trolley to detect the material's height and position, and then moves backward sequentially to place the material. Reciprocating placement uses the trolley to move back and forth between the two ends of the buffer cabinet to place the material.

[0004] Step-type fabric feeding primarily relies on photoelectric detection. In practical applications, false detections, obstructions from foreign objects, or detector malfunctions can cause abnormalities in the fabric stacking height and uniformity of the feed carriage. Furthermore, when the fabric height needs to be changed, adjustments can only be made qualitatively through visual monitoring of the photoelectric detection, failing to achieve quantitative adjustments to ensure uniformity and continuity. Reciprocating fabric feeding, on the other hand, initially results in a lower fabric height, requiring multiple cycles to reach a certain level before discharging for further production, thus lacking flexibility in fabric discharging time. Summary of the Invention

[0005] This invention provides a method, device, equipment, medium, and product for controlling the material feeding carriage of a material buffer cabinet, which can increase the detection range of material level height and reduce feeding abnormalities caused by photoelectric detection; at the same time, it can quantitatively adjust two sets of feeding times to achieve uniform and continuous feeding, as well as quantitative and flexible adjustment of height and precise feeding.

[0009] When the fabric waiting time is less than the second time, the fabric carriage is controlled to lay fabric at the current position until at least one of the two sets of high material level photoelectric detectors located at the front of the fabric carriage is blocked. Then the fabric carriage is controlled to return to perform the target operation.

[0010] When the fabric waiting time is detected to be greater than or equal to the second time, the fabric trolley is controlled to start moving forward until at least one of the two sets of high material level photoelectric detectors located at the front of the fabric trolley is detected to be blocked, at which point the fabric trolley is controlled to return to perform the target operation.

[0011] According to another aspect of the present invention, a material buffer cabinet fabric trolley control device is provided, the device comprising:

[0012] The first control module is used to control the fabric carriage to start spreading fabric, starting from the magnetic induction detection point at the start position, after detecting that the fabric carriage has started.

[0013] The second control module is used to control the fabric trolley to perform a target operation when it is detected that at least one of the two sets of high-level photoelectric detectors located at the front of the fabric trolley is blocked; the target operation is: to control the fabric trolley to start running backward, and after the fabric trolley has run backward for a first time, to control the fabric trolley to stop running and to control the timer to start counting to obtain the fabric waiting time;

[0014] The third control module is used to control the fabric carriage to lay fabric at the current position when the fabric waiting time is less than the second time, until at least one of the two sets of high material level photoelectric detectors located at the front of the fabric carriage is blocked, and then control the fabric carriage to return to perform the target operation.

[0015] The fourth control module is used to control the fabric carriage to start moving forward when the fabric waiting time is detected to be greater than or equal to the second time, until at least one of the two sets of high material level photoelectric detectors located at the front of the fabric carriage is blocked, and then control the fabric carriage to return to perform the target operation.

[0017] At least one processor; and

[0018] A memory communicatively connected to the at least one processor; wherein,

[0033] Example 1

[0034] Figure 1 This is a flowchart illustrating a material buffer cabinet fabric trolley control method according to an embodiment of the present invention. This embodiment is applicable to the control of material buffer cabinet fabric trolleys. The method can be executed by the material buffer cabinet fabric trolley control device of this embodiment, which can be implemented in software and / or hardware, such as... Figure 1 As shown, the method specifically includes the following steps:

[0035] S101. When the start of the fabric carriage is detected, the fabric carriage is controlled to start spreading fabric, starting from the magnetic induction detection point of the start position.

[0036] In this embodiment, the fabric trolley (hereinafter referred to as the trolley) is positioned above the material buffer cabinet, and the fabric trolley moves back and forth between the two ends of the material buffer cabinet.

[0037] Compared to the prior art which installs a set of high material level photoelectric detectors and a set of low material level photoelectric detectors at the front and rear of the fabric trolley, in this embodiment, two sets of high material level photoelectric detectors are installed at the front and rear of the fabric trolley.

[0038] Specifically, when the trolley starts laying material, the laying process begins at the magnetic induction detection point at the start position. In the specific implementation, the material buffer cabinet can be configured with a front half and a rear half. Material can be laid from the front half first, and then switched to the rear half after the front half is finished. The specific switching method and process are not specifically limited in this embodiment. The operating principle of the trolley is the same when laying material in the front half and the rear half. Throughout the entire implementation process, that is, when the front half or the rear half is moving forward or backward, the trolley belt performs the material laying action. The trolley belt stops laying material only when switching between the front half and the rear half of the trolley. After the switch is completed, the trolley belt resumes laying material.

[0039] S102. When it is detected that at least one of the two sets of high-level photoelectric detectors located at the front of the fabric trolley is blocked, control the fabric trolley to perform the target operation.

[0040] The target operation is as follows: control the cloth carriage to start moving backward, and after the cloth carriage has moved backward for a certain period of time, control the cloth carriage to stop moving and control the timer to start counting to obtain the cloth waiting time.

[0041] For example, the front of the sports car can be considered as the direction in which the sports car moves forward, and the rear of the sports car can be considered as the direction in which the sports car moves backward.

[0042] It should be noted that the first time can be the travel time of the sports car moving backward to lay the fabric, which can be represented by T1 in this embodiment. This embodiment does not limit the specific length of the first time.

[0043] Specifically, when one of the two sets of photoelectric sensors (both high-level sensors) located at the front of the trolley blocks, the trolley begins to move backward. After moving, if neither set of sensors shows any obstruction signal, the trolley continues to move backward for a time T1. After the trolley stops at this position, the trolley fabric waiting timer begins to count down.

[0044] S103. When the fabric waiting time is less than the second time, control the fabric carriage to lay the fabric at the current position until at least one of the two sets of high-level photoelectric detectors located at the front of the fabric carriage is blocked. Then control the fabric carriage to return to perform the target operation.

[0045] The second time can be the waiting time for the fabric to be transported, which can be represented by T2 in this embodiment. This embodiment does not limit the specific length of the second time; the values ​​of T1 and T2 can be dynamically adjusted based on the material output flow rate.

[0046] Specifically, after the racing car stops at this position, the timer for waiting for the racing car fabric starts timing. At this time, two situations will occur. The first situation: When the waiting time of the racing car fabric < T2, control the racing car to perform fabric distribution at the current position until it is detected that one of the two photoelectric detections in front of the racing car covers one of them, then control the racing car to start moving backward for a running time of T1, and the racing car stops running. After the racing car stops at this position, the timer for waiting for the racing car fabric starts timing.

[0047] S104. When it is detected that the fabric waiting time is greater than or equal to the second time, control the fabric racing car to start moving forward until it is detected that at least one of the two high-level photoelectric detectors in front of the fabric racing car is blocked, then control the fabric racing car to return and perform the target operation.

[0048] Specifically, the second situation: When the waiting time of the racing car fabric ≥ T2, at this time the racing car starts moving forward until one of the two photoelectric detections in front of the racing car covers one of them, then the racing car starts moving backward for a running time of T1, and the racing car stops running. After the racing car stops at this position, the timer for waiting for the racing car fabric starts timing.

[0049] In the actual operation process, the above steps are repeated in a cycle to achieve step control.

[0050] In the embodiment of the present invention, the fabric racing car is configured above the material buffer cabinet, and the fabric racing car runs between the two ends of the material buffer cabinet by moving forward and backward; two groups of high-level photoelectric detectors are installed at the front and rear of the fabric racing car; by controlling the fabric racing car to start fabric distribution from the starting position magnetic induction detection point after detecting that the fabric racing car starts; when it is detected that at least one of the two high-level photoelectric detectors in front of the fabric racing car is blocked, control the fabric racing car to perform the target operation; the target operation is: control the fabric racing car to start moving backward, and when the fabric racing car moves backward for the first time, control the fabric racing car to stop running and control the timer to start timing to obtain the fabric waiting time; when the fabric waiting time is less than the second time, control the fabric racing car to perform fabric distribution at the current position until it is detected that at least one of the two high-level photoelectric detectors in front of the fabric racing car is blocked, then control the fabric racing car to return and perform the target operation; when it is detected that the fabric waiting time is greater than or equal to the second time, control the fabric racing car to start moving forward until it is detected that at least one of the two high-level photoelectric detectors in front of the fabric racing car is blocked, then control the fabric racing car to return and perform the target operation. Through the technical solution of the present invention, the detection range width of the material level height can be increased, and the fabric abnormality caused by photoelectric detection can be reduced; at the same time, the fabric distribution time of the two groups can be adjusted quantitatively, and the uniform continuity of fabric distribution and the quantitative flexible adjustment of height and accurate fabric distribution can be realized.

[0051] Optionally, after detecting the start of the fabric carrier and controlling the fabric carrier to begin spreading fabric from the start position magnetic induction detection point, the following steps are also included:

[0052] When it is detected that the two sets of high-level photoelectric detectors located at the front of the fabric trolley are not blocked, the fabric trolley is controlled to move forward and fabric is laid.

[0053] Optionally, the top view of the outer contour of the fabric trolley is rectangular, and two sets of high material level photoelectric detectors are respectively installed at the four vertices of the rectangle. The installation height of the high material level photoelectric detectors is a preset height based on the height of the material trolley.

[0054] Figure 2 This is a schematic diagram of a fabric transport vehicle and two sets of high-level photoelectric detectors in an embodiment of the present invention. Figure 2 As shown, two sets of high-level photoelectric detectors are installed at the front and rear of the fabric trolley. The installation height of the two sets of high-level photoelectric detectors at the front and rear can be at the same horizontal height (in the front view, dashed lines are used to show the complete high-level photoelectric detectors, and the size and position of the high-level photoelectric detectors have been adjusted, which do not represent the actual size and installation position of the object). The actual installation height can be set by the user according to actual needs or experience based on the height of the material trolley.

[0055] For example, the top view of the outer contour of the fabric sports car is rectangular, and two sets of high-level photoelectric detectors are respectively installed at the four vertices of the diagonal of the rectangle to ensure that the detection range is maximized.

[0056] Optionally, once the fabric trolley starts running, the control timer stops and resets to zero, restarting the timing the next time the fabric trolley stops running.

[0057] Specifically, once the fabric sports car starts moving, the fabric waiting timer stops and resets to zero, and then restarts the timing the next time the fabric sports car stops running.

[0058] Optionally, when the induction switch at the first end of the material buffer cabinet detects that the fabric trolley has arrived at the first end of the material buffer cabinet, and detects that at least one of the two sets of high-level photoelectric detectors located at the front of the fabric trolley is blocked, the forward and backward direction of the fabric trolley is reversed and the fabric trolley is controlled to perform the target operation, and the fabric trolley is controlled to run towards the second end of the material buffer cabinet.

[0059] In this embodiment, a material trolley is mounted above the material buffer cabinet. The trolley moves back and forth, distributing material continuously and evenly within the material buffer cabinet at a certain stacking height. In the specific implementation, inductive switches are installed at both ends of the material buffer cabinet (the starting and ending ends corresponding to the trolley's forward and backward movement) to detect whether the trolley has reached one end of the material buffer cabinet. Specifically, when the inductive switch at the first end (one end) of the material buffer cabinet detects that the trolley has arrived at the first end, and detects that at least one of the two sets of high-level photoelectric detectors located at the front of the trolley is blocked, the forward and backward direction of the trolley is reversed, and the trolley is controlled to perform the target operation, moving towards the second end (the other end) of the material buffer cabinet. It should be noted that the first and second ends may alternate depending on the actual operation of the trolley; only the forward and backward direction of the trolley needs to be changed, while the overall operating logic remains the same.

[0060] Optionally, when the forward and backward direction of the fabric trolley is reversed, the two sets of high-level photoelectric detectors located at the front of the fabric trolley stop working, and the two sets of high-level photoelectric detectors located at the rear of the fabric trolley start working instead.

[0061] In this embodiment, when the forward and backward direction of the fabric trolley is reversed, it can be understood that the rear of the fabric trolley is actually running as the front of the trolley. At this time, the two sets of high material level photoelectric detectors located at the front of the fabric trolley need to be stopped and replaced by the two sets of high material level photoelectric detectors located at the rear of the fabric trolley.

[0062] As an exemplary description of an embodiment of the present invention Figure 3 This is a flowchart illustrating a fabric control method based on a combination of photoelectric detection and stepping time for a yarn-making line buffer cabinet carriage, as described in an embodiment of the present invention. Figure 3 As shown, the method includes the following steps:

[0063] Step a: Start the sports car.

[0064] Step b, front half of the cabinet fabric.

[0065] Step c: Does at least one of the two sets of photoelectric detectors block out? If not, proceed to step d; if yes, proceed to step e.

[0066] Step d: The sports car moves forward to move the fabric.

[0067] Step e, the running time T1 for the sports car to reverse.

[0068] Step f: Timer starts counting.

[0069] Step g: Is the fabric waiting time ≥ T2? If yes, return to step d; otherwise, proceed to step h.

[0070] Step h, current position of the cloth.

[0071] Step i: Does at least one of the two sets of photoelectric detectors block out the light? If yes, proceed to step j; if no, proceed to step k.

[0072] Step j: Start the sports car and move it backward.

[0073] Step k: Fabric at the current position.

[0074] Specifically, after executing step k, return to execute step g.

[0075] The technical solution of this invention provides a fabric control scheme for a yarn-making line buffer cabinet carriage based on a combination of photoelectric detection and stepping time. This scheme combines two pairs of high-level photoelectric detectors and a series of fabric placement times in a logically integrated fabric placement process. This invention increases the detection range of material level height and reduces fabric placement anomalies caused by photoelectric detection. Simultaneously, it allows for quantitative adjustment of the two sets of fabric placement times, achieving uniform and continuous fabric placement, as well as flexible and precise quantitative adjustment of height.
