Description

Technical Field

[0001] The invention relates to the technical field of box-splitting machines, in particular to a double-helix synchronously controlled square box-splitting device and a driving motor control system. Background Art

[0002] In square box processing equipment, it is usually necessary to separate the overlapping square lunch boxes and make them enter the processing area one by one, so as to facilitate filling, trimming and other processing of a single portion. Therefore, there are often requirements for the position and size of the separated square boxes. They cannot deviate too much or tilt and fall, causing local damage and jamming on the box separating machine. In the prior art, these lunch boxes are usually square.

[0003] The material dividing device of the prior art uses two motors to drive two cylinders with arc grooves on the cylinders. During the rotation of the two cylinders, a square box is engaged between the arc grooves of the two cylinders for each rotation. As the rotation continues, the square box disengages from the arc groove to achieve separate material discharge. However, the square boxes in the prior art are easily misplaced or deflected at an angle, and even two square boxes are discharged at a time. Therefore, manual resetting is required, which affects normal production and thus has low production efficiency.

[0004] The existing Chinese patent application with publication number CN113291543A discloses a box separation component and an automatic box separation and box dropping mechanism. The box separation component can be used for loosening and separating boxes, and includes a spiral box dropping block, a box separation block and a slide cam block coaxially arranged through a rotating shaft, a spiral groove is arranged on the outer periphery of the spiral box dropping block, and a cam slide is arranged on the outer periphery of the slide cam block; the automatic box separation and box dropping mechanism can achieve the purpose of loosening, separating and dropping boxes under the action of a driving force, and includes a frame, a box separation component, a box loosening component, a driving device and a limit component. The driving device is dynamically connected to the box separation component, and the limit component is limitedly arranged around the box placement position of the frame. The box loosening component is arranged on the frame and can be fitted in the cam slide.

[0005] The above patent solution also uses a spiral groove for material distribution, but the size of the spiral groove is fixed and cannot cope with square boxes of different sizes and thicknesses, and the spiral groove does not necessarily fit the hand-held edge of the square box. Therefore, the accuracy of adjusting the falling posture of the square box by adjusting the speed of the driving motor is very low, which cannot meet the use requirements and cannot ensure the stability of the falling posture of the square box, affecting subsequent operations and processing.

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0050] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0051] Example 1

[0052] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a double-helix synchronously controlled square box dispensing device, including a supporting mechanism, a feeding mechanism and an adjusting mechanism. The falling position and posture of the square box 102 are controlled by adjusting the rotation speed of the driving motor 400 at each corner, and adaptive clamping and positioning are performed for the hand-held edge 103 of square boxes 102 of different specifications, and precise locking is performed without affecting the falling, thereby improving the control accuracy of the falling posture of the square box 102, and at the same time realizing the statistics of the number of times the square box 102 falls and the real-time collection of the falling posture information.

[0053] Specifically, a double-helix synchronously controlled square box material distributing device comprises:

[0054] The supporting mechanism includes a bracket 100 and a conveyor belt 101 rotatably arranged in the bracket 100, and a square box 102 is movably fitted on the conveyor belt 101;

[0055] The material discharging mechanism includes a material discharging hopper 200 and a material discharging column 201 rotatably arranged in the bracket 100. The outer wall of the material discharging column 201 is provided with a spiral groove 202. The upper end surface of the square box 102 is provided with a hand-held edge 103. The hand-held edge 103 is slidably arranged in the spiral groove 202 and slides along the inner wall thereof.

[0056] The adjustment mechanism includes a limit plate 300 disposed below the outlet of the lower hopper 200 and a positioning ring 301 slidably disposed on the inner wall of the lower column 201 . The positioning ring 301 slides relative to the lower column 201 so that the spiral groove 202 is in close contact with the handle edge 103 .

[0057] Among them, the unloading column 201 is driven to rotate by the driving motor 400. There are four unloading columns 201, which are respectively tightly attached to the four corners of the square box 102. The faster the driving motor 400 rotates, the faster the corner of the square box 102 that is attached to it falls. The falling posture of the square box 102 can be adjusted by controlling the rotation speed of each driving motor 400.

[0058] The output end of the driving motor 400 rotates through the bracket 100 via a bearing, and the driving motor 400 itself is fixed and does not rotate.

[0059] Preferably, a feed port is provided on the upper end surface of the bracket 100, the lower end surface of the lower hopper 200 is spliced ​​with the feed port, a limit plate 300 is arranged on the lower end surface of the feed port, and the square box 102 enters between each limit plate 300 from the lower hopper 200 through the feed port.

[0060] Among them, the lower hopper 200 is a hollow oblique pyramid shape, and there are four limit plates 300 respectively arranged on the four sides of the feed port. The square box 102 falls in an overlapping state in the initial state. The limit plates 300 prevent the square box 102 from being angularly deflected, resulting in a displacement of the position after falling.

[0061] Furthermore, the interior of the material discharge column 201 is hollow, and the spiral groove 202 penetrates into the interior of the material discharge column 201. The positioning ring 301 is also a hollow circular ring and is slidably arranged on the inner wall of the material discharge column 201. The positioning ring 301 is also penetrated by a spiral groove 202. When the positioning ring 301 and the material discharge column 201 are relatively displaced, the overlapping area of ​​the two spiral grooves 202 is reduced, thereby jointly clamping the handle edge 103.

[0062] Among them, the spiral groove 202 is a spiral-shaped groove, and the width of the groove is greater than the thickness of the hand-held edge 103 in the square box 102. When the unloading column 201 rotates, the hand-held edge 103 slides along the spiral groove 202 and causes the square box 102 to move downward. The faster the unloading column 201 rotates, the faster the corners of the square box 102 in this area fall. By adjusting the rotation speed of the unloading column 201 at the four corners, the falling posture of the square box 102 can be adjusted.

[0063] More preferably, an adjusting column 2001 is provided inside the unloading column 201, a connecting rod 2002 is rotatably provided on the inner wall of the positioning ring 301, a sliding groove 2003 is penetrated by the adjusting column 2001, a ball 2004 is rolled in an array on the inner wall of the spiral groove 202, and a second elastic member 2009 is movably provided on the inner wall of the positioning ring 301, and each connecting rod 2002 rotates simultaneously and penetrates the second elastic member 2009.

[0064] Among them, there are three connecting rods 2002 arranged in an array from bottom to top, and the connecting rod 2002 closest to the conveyor belt 101 is rotatably connected to the adjusting column 2001. The lower half of the ball 2004 is rolled on the inner wall of the spiral groove 202, and the ball 2004 on the upper and lower spiral grooves 202 jointly clamp the hand-holding edge 103, so that the hand-holding edge 103 in this area moves up and down synchronously with the unloading column 201. The control accuracy of the falling of the square box 102 is improved by increasing the motor speed, and at the same time, the friction is reduced without affecting the normal falling of the square box 102.

[0065] Furthermore, a slide rail 3001 is provided on the inner wall of one end of the limit plate 300 extending to the unloading column 201 , and two slide rails 3001 are provided in parallel, and a reciprocating block 3002 and a follower block 3003 are slidably provided on the slide rails 3001 .

[0066] Preferably, a guide column 3004 is provided parallel to the slide rail 3001 on which the follower block 3003 is slidably set, and the follower block 3003 is slidably sleeved on the outer wall of the guide column 3004. The outer wall of the guide column 3004 is sleeved with a first elastic member 3005, and the two ends of the first elastic member 3005 are respectively connected to the inner wall of the slide rail 3001 and the follower block 3003.

[0067] Among them, the directions of the slide rail 3001 and the guide column 3004 are along the falling direction of the square box 102, the first elastic member 3005 is a spring, and the spring always pushes the follower block 3003 upward. In this embodiment, a rubber shift block is provided on the outer wall of the follower block 3003, and the hand-held edge 103 is in contact with the rubber shift block. The reciprocating block 3002 moves downward so that the follower block 3003 falls synchronously with the square box 102. A counter is provided on the follower block 3003. Each time the follower block 3003 falls, it represents that a square box 102 falls, thereby counting the falling square boxes 102. At the same time, a sensor is provided on the rubber shift block for detecting the inclination angles of each side of the square box 102 to determine whether they are parallel.

[0068] More preferably, a clamping block 3006 is slidably disposed on the side of the follower block 3003, and a spring is also disposed between the clamping block 3006 and the follower block 3003, so that the clamping block 3006 always has a tendency to pop outward.

[0069] Among them, the clamping block 3006 is a right-angled trapezoidal block, and the smaller bottom side is close to one side of the conveyor belt 101. The reciprocating block 3002 is driven by a cylinder to reciprocate up and down along the slide rail 3001, so that the follower block 3003 that falls when the hand-held edge 103 separates from the unloading column 201 is reset.

[0070] Preferably, a lever 3007 is provided on the side of the reciprocating block 3002 , and the lever 3007 and the oblique edge of the clamping block 3006 can slide relative to each other and engage with the right-angled edge of the clamping block 3006 .

[0071] Furthermore, a reset block 3008 is provided between the two slide rails 3001 , and a through groove 3009 and a reset slope 3029 are provided on the reset block 3008 , respectively. The lever 3007 can slide along the through groove 3009 , and the clamping block 3006 is slidably fitted with the reset slope 3029 .

[0072] In summary, when in use, after the square box 102 enters the feed port from the lower hopper 200, it slides downward along the space between the four limit plates 300. At this time, each drive motor 400 is driven to rotate synchronously, and the lowering column 201 rotates so that the hand-held edge 103 engages into the spiral groove 202 and slides along the spiral groove 202. When the hand-held edge 103 is deflected at a certain point, the speed of the two drive motors 400 at that point can be adjusted to adjust the falling posture of the square box 102. At this time, pressing the adjustment column 2001 downward drives the second elastic member 2009 to extend, so that the positioning ring 301 extends synchronously and produces relative displacement with the adjustment column 2001, and the distance between the two spiral grooves 202 is reduced. The hand-held edge 103 is clamped by the ball 2004 without affecting its rotation, thereby improving the control accuracy of the falling posture of the square box 102 controlled by the speed of the drive motor 400, and at the same time, square boxes 102 and hand-held edges 103 of different thicknesses can be accurately locked.

[0073] At the same time, when the square box 102 falls, the lever 3007 of the reciprocating block 3002 slides along the hypotenuse of the card block 3006 to the right-angled side of the card block 3006 and contacts and engages with it. As the reciprocating block 3002 slides downward at a set speed, the lever 3007 contacts the card block 3006, thereby driving the follower block 3003 to move downward. The hand-held edge 103 is attached to the rubber lever block to collect data, detect the inclination angles of each side of the square box 102, and determine whether they are parallel. When the reciprocating block 3002 falls to the reset block 3008, the hand-held edge 103 slides out of the spiral groove 202. At this time, the lever 3007 continues to slide down from the through groove 3009, and as the reciprocating block 3002 The hypotenuse of the block 3006 on the moving block 3003 fits with the hypotenuse of the reset slope 3029, so that the block 3006 is compressed inwardly until it shrinks to the point where the lever 3007 no longer contacts the block 3006. Under the push of the first elastic member 3005, the follower block 3003 is reset to the initial state along the guide column 3004. At this time, counting is performed, and the number of falling square boxes 102 is increased by one. After the reciprocating block 3002 reaches the maximum stroke, it moves upward in the opposite direction, and the lever 3007 slides along the hypotenuse of the block 3006 to the right-angled side of the block 3006 again and contacts and engages with it, thereby realizing the statistics of the number of times the square boxes 102 fall and the real-time statistics of the falling posture.

[0074] Example 2

[0075] Reference Figure 1 to Figure 9 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the unloading shovel 3014 and the unloading rod 3013 move inward again and limit the stacked square boxes 102 to ensure that only one square box 102 falls each time, realizing precise falling control, and the connecting rod 3025 falls to clamp the square box 102, realizing the connection between the completion of loading and the start of unloading of the new square box 102, making the whole material distribution process more coherent, ensuring single unloading one by one, preventing multiple overlapping blockages, and higher efficiency.

[0076] Specifically, a progressive groove 3011 is formed through the limiting plate 300 , a progressive rod 3012 is provided on the outer wall of the follower block 3003 , and a wedge block 3033 is provided at one end of the progressive rod 3012 that slides through the progressive groove 3011 .

[0077] Among them, the progressive groove 3011 is parallel to the direction of the guide column 3004, and a progressive rod 3012 is provided on the outer wall of the follower block 3003 close to the limit plate 300. The wedge block 3033 is a right-angled triangle block, and the right-angled side is in contact with the progressive rod 3012.

[0078] Preferably, a material discharge rod 3013 is slidably provided on one side of the limit plate 300 close to the upper end of the material discharge column 201, and a material discharge shovel 3014 is provided on one end of the material discharge rod 3013 extending into the limit plate 300, and a wedge-shaped groove 3015 is opened at the other end of the material discharge rod 3013, and the wedge block 3033 slides and fits with the wedge-shaped groove 3015.

[0079] Among them, the wedge-shaped groove 3015 is a parallelogram. When the wedge block 3033 fits the wedge groove 3015 and moves upward, the discharge rod 3013 moves outward as a whole, so that the discharge shovel 3014 stops limiting the stacked square boxes 102, and the square boxes 102 fall as a whole. Then the wedge block 3033 reaches the highest point and moves downward under the pull of the first elastic member 3005. The discharge shovel 3014 and the discharge rod 3013 move inward again and limit the stacked square boxes 102 to ensure that only one square box 102 falls at a time, thereby achieving precise falling control.

[0080] Furthermore, a sliding hoop 3016 is fixedly provided on the outer wall of the limiting plate 300, a lifting rod 3017 is slidably provided inside the sliding hoop 3016, and an inclined groove 3018 is inclined on the lifting rod 3017. A cylinder 3019 is rotatably provided on the outer wall of the discharge rod 3013, and the cylinder 3019 is slidably provided in the inclined groove 3018.

[0081] The inclined direction of the inclined groove 3018 is the same as that of the wedge-shaped groove 3015, so that when the unloading rod 3013 slides outward, the lifting rod 3017 is driven to move upward.

[0082] Preferably, a third elastic member 3021 is provided between the unloading rod 3013 and the limiting plate 300, and the third elastic member 3021 enables the unloading rod 3013 to always have a tendency to slide inwards.

[0083] More preferably, a locking groove 3022 is formed through the unloading column 201 , a locking rod 3023 is vertically provided on the outer wall of the adjusting column 2001 , the locking rod 3023 slides through the locking groove 3022 , a ring 3024 is rotatably sleeved on the outer wall of the locking rod 3023 , and a connecting rod 3025 is provided between the ring 3024 and the lifting rod 3017 .

[0084] Among them, the ring 3024 makes it possible to control the movement of the locking rod 3023 when the adjusting column 2001 and the unloading column 201 rotate, thereby driving the adjustment column 2001 to move. In this embodiment, the two spiral grooves 202 do not overlap in the initial state, so that the hand-holding edge 103 of the square box 102 cannot enter the spiral groove 202. When the lifting rod 3017 moves upward, the locking rod 3023 and the adjusting column 2001 are driven to move upward through the connecting rod 3025, so that the two spiral grooves 202 overlap, and the hand-holding edge 103 of the square box 102 enters the spiral groove 202 normally.

[0085] In summary, during use, when the current square box 102 falls off to the conveyor belt 101, the follower block 3003 first rebounds to the highest point, and then moves downward and resets to the initial state under the pull of the first elastic member 3005. When the follower block 3003 slides upward to the highest point, the wedge block 3033 moves upward in accordance with the wedge groove 3015, and the discharge rod 3013 moves outward as a whole, so that the limit of the stacked square boxes 102 by the discharge shovel 3014 disappears, and the square box 102 falls as a whole. Then the wedge block 3033 reaches the highest point and moves downward to the initial state under the pull of the first elastic member 3005. The discharge shovel 3014 and the discharge rod 3013 move inward again and limit the stacked square boxes 102 to ensure that only one square box 102 falls at a time, thereby achieving precise falling control.

[0086] At the same time, when the unloading rod 3013 moves outward, the cylinder 3019 slides in the inclined groove 3018, driving the lifting rod 3017 to move upward, so that the connecting rod 3025 drives the locking rod 3023 and the adjusting column 2001 to move upward, so that the two spiral grooves 202 overlap, and the hand-holding edge 103 of the square box 102 enters the spiral groove 202 normally. When the unloading rod 3013 is reset to the initial state, it retracts inward, so that the connecting rod 3025 drives the adjusting column 2001 to fall and clamp the square box 102 located in the spiral groove 202, thereby realizing the connection between the completion of loading and the start of unloading of the new square box 102, making the entire material distribution process more coherent, ensuring single unloading one by one, preventing multiple overlapping blockages, and higher efficiency.

[0092] The execution unit includes an execution processor, and a speed adjustment module is configured on the execution processor. The speed adjustment module is used to adjust the current state of the drive motor 400 according to input adjustment information to achieve control of the drive motor 400.

[0093] More preferably, if Fig.11 As shown, the four sides of the square box 102 are named B1, B2, B3, and B4 clockwise starting from the narrow side on the left, and the four hand-held sides 103 in contact with the unloading column 201 are named A1, A2, A3, and A4 starting from the upper left corner. The rectangular length of the square box is c and the width is d.

[0094] More preferably, in this embodiment, the sensor records the inclination angles of B1, B2, B3, and B4 respectively, and the "inclination angle" in the inclination angles of B1, B2, B3, and B4 refers to the angle formed by the edge line and the horizontal plane. Under normal circumstances, the angle between the four sides of the square box 102 and the horizontal plane, that is, the inclination angle, is 0°. The clockwise rotation angle of the four sides of the square box 102 relative to the horizontal plane is positive, and the counterclockwise rotation angle is negative. The data processor records in real time when the handheld edge 103 enters the spiral groove 202, and collects and transmits the real-time data to the comparison and analysis unit.

[0095] More preferably, the judgment strategy receives the tilt angle data of B1, B2, B3, and B4, and compares them one by one, and judges the angle with the largest deviation among A1, A2, A3, and A4 according to the comparison with the discrete degree of the tilt angles of the four sides. And compare it with the average value of the four angles to determine the deviation direction, and then calculate it according to the deviation calculation formula The deviation value is calculated as follows:

[0096] ;

[0098] Furthermore, the comparative analysis unit is based on The deviation value generates the adjustment information of the speed change value of the drive motor 400, according to The deviation direction generates adjustment information for increasing or decreasing the speed of the drive motor 400, and transmits the two types of adjustment information to the execution unit.

[0099] The speed regulating module controls the current input state of the driving motor 400 according to the regulating information, thereby completing the speed control of the driving motor 400 .

The data acquisition unit continues to collect the position information of the square box 102 and transmits it to the comparison and analysis unit and the feedback unit in real time. The feedback unit compares and analyzes the position information and the deviation before and after adjustment.

When the deviation increases, the reverse speed adjustment information of the drive motor 400 is output to control the speed of the drive motor 400 until the deviation decreases, and the reverse adjustment is continued until the deviation is less than the set value.
