Description

Technical Field

[0001] This invention relates to the field of cardboard box production line processing, and in particular to a sensor-controlled self-adjusting automatic cardboard box flipping and packing production line and its driving and control method. Background Technology

[0002] Many goods require specialized packaging cartons, on which various product designs are printed. After the cartons are initially formed, designs are printed onto the cardboard using a laser printing machine. After one side is printed, the carton needs to be flipped to print designs on the other sides or for subsequent processing. Manually flipping the cartons undoubtedly increases labor costs and workload. Therefore, designing a highly efficient and energy-saving carton flipping structure on the carton processing line to improve processing efficiency is a problem that needs to be solved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a sensor-controlled self-adjusting automatic carton flipping and packing production line and its driving and control method. By performing operations such as sliding support, status detection and corresponding airflow impact on the carton board, the tilting and flipping operation of the carton board is completed efficiently and energy-savingly, which improves the processing efficiency of the carton board production line to a certain extent.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention provides a sensor-controlled self-adjusting automatic carton flipping and packing production line, including an upstream conveyor belt, a guide frame and a sliding assembly fixedly installed on the upper side of the guide frame, a slide plate slidably mounted on the top side of the guide frame, a lateral drive device located on one side of the slide plate and a spring fixing block located on the other side of the slide plate are fixedly mounted thereon, the output side of the lateral drive device is connected to one side of the slide plate, a tension spring is connected between the spring fixing block and the other side of the slide plate, and multiple continuously distributed notches are formed on the top side of the slide plate. The sliding assembly includes an inclined frame and a vertical frame located below the inclined frame. A first airflow assembly is embedded in the inclined frame, and the first airflow assembly is equipped with multiple first air jets. A second airflow assembly and a bottom sensing mechanism located below the second airflow assembly are embedded in the vertical frame. The bottom sensing mechanism is located above the slide plate, and a downstream conveyor belt is located above the slide plate at a horizontal height between the bottom sensing mechanism and the second airflow assembly. The second airflow assembly is equipped with a high-level distance sensor and multiple second air jets distributed on both sides of the high-level distance sensor, and the bottom sensing mechanism is equipped with a low-level distance sensor.

[0006] As a preferred technical solution of the present invention: a first guide roller is provided at the top of the inclined frame, and a second guide roller is provided at the connection position between the inclined frame and the vertical frame. The first guide roller is located below the downstream end of the upstream conveyor belt.

[0007] As a preferred technical solution of the present invention: the high-position distance sensor is located in the middle of the second airflow assembly, and the number of second jet holes on both sides of the high-position distance sensor of the second airflow assembly is the same and the distribution positions are symmetrical.

[0008] As a preferred technical solution of the present invention: the lower end of the vertical frame is fixedly connected to the guide base frame, a guide groove is opened at the bottom of the vertical frame, the slide plate passes horizontally through the guide groove, and the bottom sensing mechanism is located on the upper side of the guide groove.

[0009] As a preferred embodiment of the present invention, the structural dimensions of the recess on the top side of the skateboard are matched with the structural dimensions of the side edge of the cardboard board.

[0010] As a preferred technical solution of the present invention: the transverse drive device adopts a pneumatic mechanism, and the output end of the transverse drive device is provided with an output shaft, which is fixedly connected to the slide plate.

[0011] This invention provides a driving control method for a sensor-based self-adjusting automatic carton flipping and packing production line, comprising the following steps:

[0012] (i) The upstream conveyor belt transports the printed cardboard to the end of the upstream conveyor belt. After the center of gravity of the cardboard moves away from the upstream conveyor belt, the front end of the cardboard begins to sink.

[0013] (ii) The cardboard first falls on the inclined frame and then continues to slide down the inclined frame. When the bottom of the cardboard falls into the notch of the sliding plate, the low-position distance sensor detects that there is an object within a certain distance range. Then, the lateral drive device and the first airflow component are activated. The lateral drive device drives the sliding plate to move laterally once, and the direction of movement is towards the lateral drive device. The first airflow component sprays multiple first jet holes towards the cardboard multiple times at intervals.

[0014] (3) The high-position distance sensor and the low-position distance sensor sense and detect the distance of the corresponding position of the cardboard in real time. Let the distance sensed and detected by the high-position distance sensor in real time be Da, and let the distance sensed and detected by the low-position distance sensor in real time be Db. ① When Da < Db, the first air flow component controls the first air jet hole to jet air towards the cardboard. Let the real-time single-jet air volume controlled and output by the first air flow component be Qx, and let △Dx = Db - Da. Then the real-time single-jet air volume Qx ∝ (1 / △Dx). ② When Da > Db, the first air flow component is closed, and the second air flow component controls the second air jet hole to jet air towards the cardboard. Let the real-time single-jet air volume controlled and output by the second air flow component be Qy, and let △Dy = Da - Db. Then the real-time single-jet air volume Qy ∝ (1 / △Dy). ③ When the low-position distance sensor senses that the distance information of the cardboard disappears, the second air flow component is closed, and at the same time, the crosswise movement driving device releases the slide plate, and the slide plate returns to the initial position under the action of the tension spring. Among them, the distance that the crosswise movement driving device drives the slide plate to move horizontally is less than the distance sensed and detected by the low-position distance sensor when the bottom end of the cardboard falls into the notch.

[0015] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, through the inclined plane frame and the vertical frame, the cardboard falling from the upstream conveyor belt is smoothly slid onto the upper side of the slide plate. The crosswise movement driving device drives the slide plate and the bottom of the cardboard to move. The first air flow component blows air towards the upper part of the cardboard, starting to blow the cardboard away from the material sliding component and tilting it towards the downstream conveyor belt direction. And after the cardboard reaches a certain inclination degree, the first air flow component is closed, and the second air flow component is opened to "accelerate" the action of tilting the cardboard towards the downstream conveyor belt.

[0017] 2. The present invention senses and detects the "entry" and "departure" states of the cardboard on the slide plate through the low-position distance sensor, and performs real-time distance detection on the corresponding position of the cardboard through the high-position distance sensor and the low-position distance sensor. According to the change of the inclination state of the cardboard, the output air volume is controlled specifically, and the tilting and flipping operations of the cardboard are completed efficiently and energy-savingly.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] Example 1

[0031] Please see Figure 1The cardboard board 3 has its pattern printed on one side by the laser printing mechanism 2. A sliding assembly 4 and a guide frame 8 are configured below the downstream end of the upstream conveyor belt 1. The sliding assembly 4 is fixedly installed on the upper side of the guide frame 8. A sliding plate 9 is also slidably installed on the top side of the guide frame 8. The sliding engagement structure between the sliding plate 9 and the guide frame 8 has many implementation methods in the prior art, which will not be elaborated upon in this invention and will not affect the overall technical solution of this invention. A transverse drive device 10 and a spring fixing block 11 are fixedly installed on the top side of the guide frame 8. The transverse drive device 10 is located on one side of the sliding plate 9, and its output side is connected to one side of the sliding plate 9. The spring fixing block 11 is located on the other side of the sliding plate 9, and a tension spring 12 connects the spring fixing block 11 and the other side of the sliding plate 9. The bottom sensing mechanism 7 is located above the sliding plate 9, and the downstream conveyor belt 13 is located above the sliding plate 9. The horizontal height of the downstream conveyor belt 13 is between the bottom sensing mechanism 7 and the second airflow assembly 6. The spring fixing block 11 is located below the downstream conveyor belt 13.

[0032] Please see Figure 2 The material sliding assembly 4 includes an inclined frame 401 and a vertical frame 402. The vertical frame 402 is located below the inclined frame 401, and its lower end is fixedly connected to the guide base frame 8. A guide groove 405 is provided at the bottom of the vertical frame 402. Figure 3 , Figure 4The total height of the combined structure of the vertical frame 402 and the inclined frame 401 is less than the height of the carton board 3 in the inclined state. The first guide roller 403 is located at the top of the inclined frame 401, and the second guide roller 404 is located at the connection between the inclined frame 401 and the vertical frame 402. During the downward sliding process of the carton board 3, the frictional resistance of the carton board 3 under the rolling of the first guide roller 403 and the second guide roller 404 is smaller, avoiding unnecessary wear of the carton board 3 when sliding. The first guide roller 403 is located below the downstream end of the upstream conveyor belt 1, and only a certain gap is required between the first guide roller 403 and the downstream end of the upstream conveyor belt 1 to ensure that the carton board 3 can slide smoothly down the inclined frame 401. The first airflow assembly 5 is embedded in the inclined frame 401, and the first airflow assembly 5 is equipped with multiple horizontal air outlet first jet holes 501. The vertical frame 402 is embedded with a second airflow assembly 6 and a bottom sensing mechanism 7. The bottom sensing mechanism 7 is located above the guide groove 405 and below the second airflow assembly 6. The second airflow assembly 6 is equipped with multiple horizontally venting second jet holes 602, and the bottom sensing mechanism 7 is equipped with a low-position distance sensor 701. Multiple continuously distributed notches 901 are opened on the top side of the slide plate 9, and the slide plate 9 passes horizontally through the guide groove 405. The transverse drive device 10 adopts a pneumatic mechanism, and the output shaft 1001 of the transverse drive device 10 is fixedly connected to the slide plate 9 (in this invention, the outward output positioning movement operation is achieved through the pneumatic mechanism and its output shaft 1001, which is a common technology in pneumatic devices. The specific structure of the pneumatic mechanism and the output shaft 1001 is not given in this invention and will not be described in detail, which does not affect the implementation of the overall technical solution of this invention).

[0033] Please see Figure 3 , Figure 4 After the cardboard board 3 slides down to the notch 901 on the slide plate 9, the low-position distance sensor 701 detects the cardboard board 3, and the first airflow component 5 is activated to start blowing air onto the upper part of the cardboard board 3, blowing the upper part of the cardboard board 3 toward the downstream conveyor belt 13.

[0034] Please see Figure 5 , Figure 6 Impacted by the airflow from the first airflow component 5, the cardboard board 3 gradually tilts towards the downstream conveyor belt 13. When the cardboard board 3 falls directly down from a completely vertical position towards the downstream conveyor belt 13, the first airflow component 5 can be shut off, and the second airflow component 6 can be activated to assist in accelerating the tilting process of the cardboard board 3.

[0035] Please see Figure 6 , Figure 7The cardboard board 3 is impacted by the output airflow of the second airflow assembly 6, and accelerates to tilt towards the downstream conveyor belt 13. When the low-position distance sensor 701 can no longer detect the cardboard board 3, the second airflow assembly 6 stops outputting airflow, and the transverse drive device 10 also releases the slide plate 9, which returns to its initial position (as in position 1).

[0036] Please see Figure 8 The second airflow assembly 6 is equipped with a high-position distance sensor 601 and a plurality of second jet holes 602 distributed on both sides of the high-position distance sensor 601. The high-position distance sensor 601 is located in the middle of the second airflow assembly 6, and the number of second jet holes 602 on both sides of the high-position distance sensor 601 is the same and their distribution positions are symmetrical.

[0037] Please see Figure 1 , Figure 9 The structural dimensions of the recess 901 on the top side of the skateboard 9 are matched with the structural dimensions of the side edge of the cardboard board 3. For example, a wear-resistant rubber layer can be embedded on the top side of the skateboard 9, and the recess 901 is opened on the upper side of the wear-resistant rubber layer to reduce the impact between the cardboard board 3 and the recess 901 when it slides down, thus protecting the cardboard board 3.

[0038] Example 2

[0039] This invention relates to a driving control method for a sensor-based self-adjusting automatic carton flipping and packing production line, which mainly includes the following:

[0040] First, the upstream conveyor belt 1 transports the cardboard board 3, which has already been printed by the laser printing mechanism 2, to the end of the upstream conveyor belt 1. After the center of gravity of the cardboard board 3 leaves the upstream conveyor belt 1, the front end of the cardboard board 3 (that is, the side end of the cardboard board 3 that leaves the upstream conveyor belt 1 first) begins to sink.

[0041] Secondly, the cardboard box board 3 first lands at the position of the inclined plane frame 401, and then continues to slide down along the inclined plane frame 401. When the bottom end of the inclined and sliding cardboard box board 3 falls into the notch 901 of the sliding plate 9, when the low-position distance sensor 701 senses and detects that there is an object within a certain distance range [the low-position distance sensor 701 in the present invention has two functions. One is to sense and detect the occlusion of an object within a certain distance range (the first principle of action is actually the sensing and detection of distance. When there is no object within a certain distance range, the low-position distance sensor 701 cannot sense and detect the distance information. After the object occludes, the signal state of the distance information changes, similar to the rising-edge trigger signal in a logic circuit, changing from "0" to "1", so it can be used as a judgment signal for detecting when the bottom end of the cardboard box board 3 falls into the notch); the other is that after the bottom end of the cardboard box board 3 falls into the notch 901, the distance of the cardboard box board 3 is detected in real time], the transverse movement driving device 10 and the first air flow component 5 are started. The transverse movement driving device 10 drives the sliding plate 9 to perform a transverse movement (the distance that the transverse movement driving device 10 drives the sliding plate 9 to perform a transverse movement is less than the distance sensed and detected by the low-position distance sensor 701 when the bottom end of the cardboard box board 3 falls into the notch 901), and the moving direction is towards the transverse movement driving device 10. The first air flow component 5 jets air at the cardboard box board 3 through multiple first air jet holes 501 in a multiple intermittent manner (multiple intermittent jetting, for example, each jetting lasts for only 0.5S, and the interval between each jetting is 0.5S, and it jets multiple times).

[0042] Then, the high-position distance sensor 601 and the low-position distance sensor 701 sense and detect the distance of the corresponding position of the cardboard box board 3 in real time. Let the distance sensed and detected by the high-position distance sensor 601 in real time be Da, and let the distance sensed and detected by the low-position distance sensor 701 in real time be Db. When the cardboard box board 3 just slides down, the distance between the cardboard box board 3 and the high-position distance sensor 601 is relatively close, and the distance between the cardboard box board 3 and the low-position distance sensor 701 is relatively far.

[0043] 1. When Da < Db, the first air flow component 5 controls the first air jet holes 501 to jet air at the cardboard box board 3. Let the real-time single-jet air volume controlled by the first air flow component 5 be Qx, and let △Dx = Db - Da. Then the real-time single-jet air volume Qx ∝ (1 / △Dx). The real-time single-jet air volume in the present invention refers to the air volume that should be ejected in the next time controlled according to the parameter size of the real-time △Dx. For the acquisition of this △Dx, if the system response speed is sufficient, it is preferred to obtain and analyze the distance parameter information in the interval time period between adjacent jetting actions. And Qx ∝ (1 / △Dx) means that the larger △Dx is, the smaller Qx is. Combining Figure 3 、 Figure 4The closer the cardboard board 3 is to the first jet hole 501, the smaller the air volume ejected by the first jet hole 501. Of course, the minimum air volume output by the first airflow assembly 5 is still sufficient to ensure that the cardboard board 3 is blown towards the downstream conveyor belt 13 through multiple first jet holes 501. As the cardboard board 3 moves further away, to make the cardboard board 3 continue to tilt towards the downstream conveyor belt 13, the first airflow assembly 5 needs to output more air volume, impacting the increasingly distant cardboard board 3 and causing it to continuously tilt towards the downstream conveyor belt 13. In addition, for the sake of representing the relationship between the parameters, the jetting situation when Da = Db is explained separately. When Da = Db, the first jet hole 501 also ejects air, and the jetting volume can be the maximum air volume that the first airflow assembly 5 can output. This maximum air volume is the maximum air volume that the first airflow assembly 5 outputs towards the cardboard board 3, not the maximum air volume that the first airflow assembly 5 can output.

[0044] 2. When Da > Db, the first airflow component 5 is closed, and the second airflow component 6 controls the second jet nozzle 602 to spray air towards the cardboard board 3. Let the real-time single jet volume controlled by the second airflow component 6 be Qy, and let ΔDy = Da - Db, then the real-time single jet volume Qy ∝ (1 / ΔDy). It is worth noting that in this state, the cardboard board 3 is already tilted towards the downstream conveyor belt. The larger the value of ΔDy, the closer the cardboard board 3 is to the downstream conveyor belt 13, that is, the greater the degree of tilting. Only a small amount of airflow needs to be blown onto the cardboard board 3. Simply put, the farther away the cardboard board 3 is, the smaller the output air volume.

[0045] 3. When the low-position distance sensor 701 detects that the distance information of the cardboard board 3 has disappeared (similar to the principle of initially detecting the cardboard board 3 blocking signal, the distance was originally detectable, but suddenly the distance information cannot be detected, similar to the falling edge trigger signal in the logic circuit, changing from "1" to "0", which can be used as a judgment signal to detect when the bottom end of the cardboard board 3 is removed from the notch 901. At this time, the bottom end of the cardboard board 3 has been removed from the notch 901, and the cardboard board 3 is rapidly "lying flat" on the downstream conveyor belt 13), the second airflow assembly 6 is turned off, and at the same time the transverse drive device 10 releases the slide plate 9, which is returned to the initial position by the tension spring 12.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
