Description

Technical Field

[0001] This invention relates to the field of steel production, and more specifically, to a method, apparatus, baler system, and storage medium for controlling baling heads. Background Technology

[0002] After the bar stock is produced, it needs to be bundled using a baling machine for subsequent processes. The baling head of the bar baling machine is driven by a hydraulic system that uses a hydraulic cylinder to move the baling head up and down. When not performing baling work, the baling head is in the initial high position. When baling is required, it descends to the bundling position. For a single baling operation to occur, the baling head can only descend and begin the baling action when a baling command is received and the baling head is detected to be in the initial position.

[0003] However, during normal production, there may be situations where the baling head is not in its initial position, which prevents the baling head from performing its next action and thus affects production efficiency. Summary of the Invention

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0059] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0060] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0061] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0062] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0063] In existing technology, when the baling head receives a baling command, it can only execute the descent command when it is in a high position. This means the proximity switch in the high position must be able to detect the baling head; otherwise, the baling head will not descent. If the baling head doesn't move, manual inspection of the baling machine is required, and manual intervention is necessary, impacting production efficiency. Furthermore, during normal production, factors such as low hydraulic system pressure or prolonged periods without depressurization of the baling system can also cause the baling head to descend slowly, resulting in no signal from the high-position proximity switch, or the high-position proximity switch may have a signal but the signal disappears after a while, thus preventing the baling head from being ready to move again.

[0064] In addition, if the bundling head descends too much, the steel on the roller conveyor is also prone to damaging the bundling head, causing a production accident.

[0065] Based on the above, embodiments of the present invention provide a baling head control method, device, baling machine system, and storage medium, which can effectively alleviate the above-mentioned technical problems.

[0066] Please refer to Figure 1 as well as Figure 2 This is a schematic diagram and interaction diagram of a baling machine system 01 provided in this application. The baling machine system 01 includes: a controller 11, a baling head 12, a roller conveyor 13, a first sensor 14, a second sensor 15, and a first proximity switch 16. The first sensor 14 is located at the material drop point 131 on the roller conveyor 13, the second sensor 15 is located at the baling machine inlet 132, and the first proximity switch 16 is located on the running trajectory of the baling head 12 at the initial position 121 of the baling head 12. The controller 11 is communicatively connected to the baling head 12, the first sensor 14, the second sensor 15, and the first proximity switch 16.

[0067] The first proximity switch 16 is used to output a low-level first electrical signal to the controller 11 when it is detected that the bundling head 12 is not in the initial position 121.

[0068] The first sensor 14 is used to detect whether there is steel at the material drop point 131 and outputs the first sensor signal to the controller 11.

[0069] The second sensor 15 is used to detect whether there is steel at the baler inlet 132 and outputs the second sensor signal to the controller 11.

[0070] The controller 11 is used to acquire the first electrical signal, the first sensor signal, and the second sensor signal output by the first proximity switch 16, respectively. It determines whether the first electrical signal is a low-level signal. If so, it determines whether the baling head 12 reset condition is met based on the first and second sensor signals. If so, it controls the baling head 12 to reset.

[0071] like Figure 1 As shown, when the baler system 01 is running, the steel first arrives at the drop point 131 of the roller conveyor 13, and then is conveyed to the baler inlet 132 via the roller conveyor 13. The steel can be detected by the first sensor 14 when it is at the drop point 131, and by the second sensor 15 when it is at the baler inlet 132.

[0072] When the steel reaches the baler inlet 132 and is located at the initial position 121, the first proximity switch 16 can detect the baling head 12. The controller 11 controls the baling head 12 to descend and bal the steel. After the baling is completed, the controller 11 controls the baling head 12 to rise back to the initial position 121.

[0073] Corresponding to the baler system 01, this embodiment of the invention provides a baling head control method, applied to the controller 11 of the baler system 01. The baler system 01 also includes a baling head 12, a roller conveyor 13, a first sensor 14, a second sensor 15, and a first proximity switch 16. The first sensor 14 is located at the material drop point 131 on the roller conveyor 13, the second sensor 15 is located at the baler inlet 132, and the first proximity switch 16 is located on the running trajectory of the baling head 12, at the initial position 121 of the baling head 12's movement. The controller 11 is communicatively connected to the baling head 12, the first sensor 14, the second sensor 15, and the first proximity switch 16. The method includes, as follows: Figure 3 The following steps are shown:

[0074] Step S110: Acquire the first electrical signal, the first sensor signal, and the second sensor signal output by the first proximity switch 16, respectively.

[0075] Step S120: Determine whether the first electrical signal is a low-level signal.

[0076] Step S130: If yes, then determine whether the bundling head 12 reset condition is met based on the first sensor signal and the second sensor signal.

[0077] Step S140: If yes, then control the bundling head 12 to reset.

[0078] In step S110, the first electrical signal, the first sensor signal, and the second sensor signal output by the first proximity switch 16 are acquired respectively.

[0079] The initial position 121 can be the position set by the developers when the baling head 12 is not working. The first proximity switch 16 can be a proximity switch used to detect whether the baling head 12 is in the initial position 121, and outputs different electrical signals when the baling head 12 is in the initial position 121 and when the baling head 12 is not in the initial position 121. The first sensor 14 and the second sensor 15 can be the same sensor or different sensors, such as laser detectors, thermal sensors, infrared sensors, etc. The first sensor 14 can detect whether there is steel at the material drop point 131, and the second sensor 15 can detect whether there is steel at the baler inlet 132.

[0080] When the baler is running, the controller 11 can monitor and acquire the first electrical signal, the first sensor signal, and the second sensor signal output by the first proximity switch 16 in real time.

[0081] Execute step S120 to determine whether the first electrical signal is a low-level signal.

[0082] After the controller 11 obtains the first electrical signal, the first sensor signal and the second sensor signal, it determines whether the first electrical signal is a low-level signal, that is, whether the first proximity switch 16 can detect the bundling head 12.

[0083] In one embodiment, if the baling head 12 is not in the initial position 121, the first electrical signal output by the first proximity switch 16 is a low-level signal; if the baling head 12 is in the initial position 121, the first electrical signal output by the first proximity switch 16 is a high-level signal. In another embodiment, the first proximity switch 16 can also be configured to output a low-level signal when it detects the baling head 12 and a high-level signal when it does not detect the baling head 12, with subsequent judgments adjusted accordingly. This embodiment of the invention does not impose specific limitations on this.

[0084] Execute step S130. If yes, determine whether the bundling head reset condition is met based on the first sensor signal and the second sensor signal.

[0085] If the first electrical signal is low, it indicates that the baling head 12 is not at its initial position 121 and should be reset. At this time, it is necessary to determine whether the acquired first and second sensor signals are present on the roller conveyor 13 or about to reach the baler inlet 132. If the baling head 12 is directly reset to its initial position 121, but steel is being conveyed to the baler inlet 132 and requires baling, it will cause signal malfunction in the controller 11. Therefore, it is also necessary to determine whether the baling head reset condition is met based on the first and second sensor signals.

[0086] Optionally, the first sensor signal includes a signal indicating the presence of steel at the material drop point and a signal indicating the absence of steel at the material drop point; the second sensor signal includes a signal indicating the presence of steel at the inlet and a signal indicating the absence of steel at the inlet; the step of determining whether the bundling head reset condition is met based on the first sensor signal and the second sensor signal includes:

[0087] Determine whether the first sensor signal is a no-steel signal at the material drop point.

[0088] If so, determine whether the second sensor signal is the "no steel at the inlet" signal. If so, determine that the bundling head reset condition is met.

[0089] In one optional implementation, when the first sensor 14 or the second sensor 15 does not detect steel, a "no steel" signal is sent back to the controller 11; when the first sensor 14 or the second sensor 15 detects steel, a "steel present" signal is sent back to the controller 11. Therefore, it can be determined whether the first sensor signal is a "no steel" signal at the material drop point; if so, it can be determined whether the second sensor signal is a "no steel" signal at the inlet. When both the material drop point 131 and the baler inlet 132 have "no steel" signals, it is determined that the baler head reset condition is met.

[0090] Optionally, the baler system 01 further includes a roller conveyor motor, which is communicatively connected to the controller 11; the step of determining whether the baling head reset condition is met based on the first sensor signal and the second sensor signal further includes:

[0091] If the first sensor signal indicates that there is steel at the material drop point, and the second sensor signal indicates that there is no steel at the inlet, then the motor speed of the roller conveyor motor is obtained.

[0092] The first time it takes for the steel to be conveyed to the baler inlet 132 is calculated based on the motor speed and the distance from the material drop point 131 to the baler inlet 132.

[0093] The second duration of the steel-on-drop signal is obtained. The position of the steel on the roller conveyor 13 is determined based on the first duration and the second duration.

[0094] The position of the steel on the roller conveyor 13 is used to determine whether the bundling head reset condition is met.

[0095] In another alternative implementation, if the first sensor signal is a signal that there is steel at the material drop point, since there is still a distance between the material drop point 131 and the baler inlet 132, if the second sensor signal is a signal that there is no steel at the inlet, the speed-time formula can be used to determine whether the baling head 12 can be reset before the steel reaches the baler inlet 132.

[0096] Specifically, the motor speed of roller conveyor 13 can be obtained to convert it into the speed at which the steel is conveyed by roller conveyor 13. The first duration of the steel being conveyed to the baler inlet 132 is calculated from the speed of the steel conveyed by roller conveyor 13 and the distance from the drop point 131 to the baler inlet 132. Then, based on the time difference between the second duration of the steel signal detected at the drop point and the first duration, and the speed of the steel conveyed by roller conveyor 13, the current position of the steel is calculated. If this position is not at the baler inlet 132, it can be determined that the baler head reset condition is met.

[0097] Optionally, the step of determining whether the bundling head reset condition is met based on the first sensor signal and the second sensor signal further includes:

[0098] If the second sensor signal indicates that there is steel at the inlet, then it is determined that the bundling head reset condition is not met.

[0099] In another alternative implementation, if the second sensor signal acquired by the controller 11 is a steel inlet signal, then the first sensor signal can be disregarded, and the controller can be directly determined to be not in compliance with the bundling head reset condition, thereby saving the computing resources of the controller 11.

[0100] Optionally, such as Figure 4 As shown, the baler system 01 also includes a second proximity switch 17 and a baling head triangle plate 18. The second proximity switch 17 is communicatively connected to the controller 11, and the baling head triangle plate 18 is movably connected to the baling head 12. The method further includes:

[0101] If the first electrical signal is a high-level signal, then packing instructions are acquired in real time. The packing instructions include a baler head lowering instruction, a baling instruction, and a baler head raising instruction.

[0102] Based on the command to lower the baling head, control the baling head 12, the baling head triangle plate 18, and the second proximity switch 17 to lower simultaneously.

[0103] Based on the second electrical signal output by the second proximity switch 17, it is determined whether the bundling head 12, the bundling head triangle plate 18, and the second proximity switch 17 have descended to the packing position.

[0104] If so, the bundling head 12 is controlled to bundle the steel according to the bundling command.

[0105] After bundling is completed, the bundling head 12, the bundling head triangle plate 18, and the second proximity switch 17 are simultaneously raised based on the bundling head raising command. The system then determines whether the bundling head 12 has risen to its initial position 121 based on the first electrical signal.

[0106] like Figure 4 As shown, the bundling head 12 is Figure 4 The ring-shaped structure in the middle has a plane where the bundle head triangle 18 is located parallel to the plane where the bundle head 12 is located in the horizontal direction. The second proximity switch 17 maintains contact with the lower edge of the bundle head triangle 18 when the bundle head triangle 18 is not in contact with the steel. When the controller 11 controls the bundle head 12 to descend, the bundle head triangle 18 and the second proximity switch 17 descend simultaneously.

[0107] If the first electrical signal is high, the bundling head 12 is in a state ready for bundling. The controller 11 receives the bundling command in real time. Upon receiving the command, the controller 11 lowers the bundling head 12 according to the descent command, while the bundling head triangle plate 18 and the second proximity switch 17 descend along with the bundling head 12. During the descent, the controller 11 determines whether the bundling head 12 has reached the bundling position based on the second electrical signal of the second proximity switch 17. If it has reached the position, the controller stops the descent of the bundling head 12 and performs bundling according to the bundling command. After bundling is complete, the controller 11 raises the bundling head 12 according to the ascending command and determines whether the bundling head 12 has reached the initial position 121 based on the first electrical signal of the first proximity switch 16, thereby stopping the ascending of the bundling head 12.

[0108] Optionally, the second proximity switch 17 remains in contact with the bundling head triangle 18 when it is not in contact with the steel, and disengages from the bundling head triangle 18 when it comes into contact with the steel. The determination of whether the bundling head 12, the bundling head triangle 18, and the second proximity switch 17 have descended to the packing position based on the second electrical signal output by the second proximity switch 17 includes:

[0109] The system monitors in real time whether the second electrical signal changes from a high-level signal to a low-level signal. If so, it determines whether the bundling head 12, the bundling head triangle plate 18, and the second proximity switch 17 have descended to the packing position.

[0110] Control the baling head 12, the baling head triangle plate 18, and the second proximity switch 17 to stop the descent.

[0111] As an optional implementation, since the bundling head triangle 18 is movably connected to the bundling head 12, when the bundling head 12 descends to the position of the steel, the lower edge of the bundling head triangle 18 will be raised due to contact with the steel, and the connection point between the bundling head triangle 18 and the bundling head 12 ( Figure 4 (The black dot in the middle is the center) and rotate in the direction of the arrow. At this time, the second proximity switch 17 will separate from the bundling head triangle plate 18, causing the second electrical signal output by the second proximity switch 17 to change.

[0112] Therefore, when the controller 11 detects that the second electrical signal changes from a high-level signal to a low-level signal, it determines that the baling head 12, the baling head triangle plate 18, and the second proximity switch 17 have descended to the packing position, and controls the baling head 12, the baling head triangle plate 18, and the second proximity switch 17 to stop descending. It should be noted that when the controller 11 controls the baling head 12 to rise / fall, it does not actually control the baling head triangle plate 18. The baling head triangle plate 18 rises / falls along with the baling head 12 due to its mechanical connection to the baling head 12.

[0113] Optionally, determining whether the bundling head 12 has risen to the initial position 121 based on the first electrical signal includes:

[0114] The second electrical signal is acquired in real time. It is then determined whether the second electrical signal has changed from a low-level signal to a high-level signal.

[0115] If so, the baling head 12 is determined to have risen to the initial position 121, and the baling head 12 is controlled to stop rising. If not, the baling head 12 is controlled to continue rising.

[0116] In one alternative implementation, the first electrical signal output by the first proximity switch 16 can be used to determine whether the baling head 12 has reached the initial position 121. After the baling head 12 completes baling, the controller 11 controls the baling head 12 to rise while simultaneously acquiring the first electrical signal output by the first proximity switch 16.
