[0001] This invention relates to an automatic bag-dispensing machine and its usage method, belonging to the field of automatic bag-dispensing packaging technology. Background Technology

[0002] In automated production lines, the post-packaging process requires manual placement of shopping bags. One person places three shopping bags into a packaging box, which is then conveyed to the next process. This process necessitates an additional person manually placing the bags, wasting labor costs. Furthermore, human error can lead to instances where bags are not placed or are placed in short supply, resulting in low production efficiency, high error rates, and negatively impacting subsequent sales and product quality control.

[0003] Therefore, there is an urgent need to propose a new type of automatic bag-dispensing machine and method to solve the above-mentioned technical problems. Summary of the Invention

At the same time, the material handling support plate cylinder fixing plate is connected to the output end of the material handling cylinder. The material handling support plate cylinder and the suction cup are installed on the top of the material handling support plate cylinder fixing plate. The material handling support plate is provided with a through hole, and the suction cup is placed in the through hole. When the material handling cylinder moves to the low position, middle position, and high position, it triggers the low position detection magnetic switch, the middle position detection magnetic switch, and the high position detection magnetic switch located on the frame, respectively.

[0010] Preferably, the temporary storage unit includes a material temporary storage fixing frame, which is fixedly installed below the discharge port. The material temporary storage fixing frame is equipped with a material detection photoelectric switch and a magnetic detection photoelectric switch in the temporary storage area.

[0011] Preferably, the feeding unit includes a feeding cylinder, a sliding guide needle roller bearing, a sliding guide shaft, and a feeding stop rod. The feeding cylinder and the sliding guide shaft are both horizontally mounted on the frame. The feeding stop rod is slidably connected to the sliding guide shaft through the sliding guide needle roller bearing. At the same time, the feeding stop rod is connected to the feeding cylinder. When the feeding cylinder moves to the high position, it triggers the magnetic detection photoelectric switch.

[0012] Preferably, the buffer dispensing unit includes a buffer dispensing cylinder, a material temporary storage bracket, and a temporary storage bracket fixing frame. The temporary storage bracket fixing frame is fixedly installed on the frame, and the buffer dispensing cylinder is fixedly installed on the temporary storage bracket fixing frame. One end of the material temporary storage bracket is hinged to the bottom of the temporary storage bracket fixing frame. The output end of the buffer dispensing cylinder is hinged to the material temporary storage bracket. When the buffer dispensing cylinder is in its original position, it triggers the in-situ magnetic detection photoelectric switch located on the temporary storage bracket fixing frame. When the buffer dispensing cylinder moves to a high position, it triggers the position detection magnetic switch located on the temporary storage bracket fixing frame. The material temporary storage bracket is equipped with a buffer material detection photoelectric switch.

[0016] Option 2: An automatic bag-dispensing method, based on the automatic bag-dispensing machine described in Option 1, includes:

[0017] S1, Place the tote bag into the storage bin to ensure that the material detection photoelectric switch detects the tote bag;

[0018] S2, the feeding cylinder of the feeding unit is triggered by the magnetic detection switch in the original position. After the start button is pressed, the picking cylinder in the picking unit is activated. When the picking cylinder moves to the middle position, the middle position detection magnetic switch is triggered, and the picking support plate cylinder is activated, which drives the picking support plate from the high position to the low position. At the same time, the material lifting cylinder of the storage bin is activated to lift the handbag in the storage bin.

[0019] S3, the vacuum generator connected to the suction cup works. At this time, when the suction cup is in a vacuum state, the material picking cylinder moves to the high position, triggering the high position detection magnetic switch. At the same time, the negative pressure of the suction cup is not less than 2.0MPa. After maintaining this position for 0.7 seconds, the material picking cylinder resets and moves downward. When it moves to the middle position, the middle position detection magnetic switch is triggered again, and the material picking support plate cylinder moves again, driving the material picking support plate from the low position to the high position. At the same time, the material holding cylinder of the storage bin resets, causing the bag to fall naturally from the outlet. The vacuum generator resets, causing the vacuum of the suction cup to break, and the bag falls onto the temporary storage unit material temporary storage fixing rack.

[0020] S4, when the picking cylinder moves to the low position, the low position detection magnetic switch is triggered, and the trigger signal of the low position detection magnetic switch is sent to the feeding unit. When the feeding unit receives the action signal, the temporary storage area material detection photoelectric switch on the temporary storage fixing frame is triggered. If the temporary storage area material detection photoelectric switch does not detect the bag, the temporary storage area material detection photoelectric switch issues an alarm signal, indicating that the picking of materials has failed. If the temporary storage area material detection photoelectric switch detects the bag, the feeding cylinder moves to push the bag to the buffer delivery unit. When the feeding cylinder moves to the high position, the magnetic detection photoelectric switch is triggered. This cylinder is reset, and the buffer delivery cylinder of the buffer delivery unit remains in the original position, i.e., the original position magnetic detection photoelectric switch is triggered.

[0021] S5, after the feeding cylinder is reset, the in-situ detection magnetic switch is triggered, the signal is transmitted to the picking unit, the picking cylinder is activated, and the picking process is repeated. The picking process is S2-S4.

[0022] S6. After the feeding cylinder moves three times, the bag is delivered to the buffer delivery unit to complete the three counts. At the same time, the buffer material detection photoelectric switch is triggered, and the conveying unit drives the carton above it to move. When the carton is below the buffer delivery unit, the carton detection photoelectric switch is triggered, and the first clamping cylinder and the second clamping cylinder move in opposite directions at the same time to clamp the carton at the position of the first clamping cylinder.

[0023] S7, the buffer delivery cylinder of the buffer delivery unit is activated. When the buffer delivery cylinder is activated to the high position, the position detection magnetic switch is triggered. After the buffer delivery cylinder maintains the high position for 1.5 seconds, the buffer delivery cylinder is reset, and the original position magnetic detection photoelectric switch is triggered.

[0024] S8, after the buffer delivery cylinder triggers the in-situ magnetic detection photoelectric switch, the first clamping cylinder is reset, and the carton is driven to the next station by the power of the conveying unit;

[0025] S9, when the carton leaves the detection photoelectric switch, the second clamping cylinder is reset, the next carton will be transported to the position of the first clamping cylinder, the carton detection photoelectric switch is triggered, the first clamping cylinder and the second clamping cylinder act simultaneously, the front carton is clamped by the first clamping cylinder, when the buffer delivery unit has buffered three tote bags, the next delivery is carried out.

[0026] S10, when the carton enters the next station and triggers the full-track detection photoelectric switch, the carton detection photoelectric switch detects the carton on the back side, and the first clamping cylinder and the second clamping cylinder act simultaneously. After the buffer delivery unit delivers three tote bags when the delivery conditions are met, it enters a pause state, that is, the feeding cylinder remains in the reset state. The in-situ detection magnetic switch is triggered, and the picking cylinder will continue to work once. The buffer delivery unit buffers three tote bags, and the temporary storage unit stores one tote bag. When the carton leaves the full-track detection photoelectric switch, the first clamping cylinder automatically resets and continues to run automatically, completing the automatic delivery process of the tote bags.

[0027] The present invention has the following beneficial effects:

[0028] 1. This invention can automatically place the required number of shopping bags inside a carton, completely replacing manual placement operations, saving labor costs, improving work efficiency, and reducing production costs;

[0029] 2. After one carton is placed, the present invention can automatically place the next one, which has a high degree of automation, improves production efficiency, reduces production risks and error rates, and avoids affecting subsequent sales and product quality control.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0041] The connections mentioned in this invention are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0042] Specific implementation method one: Combining Figures 1-9 This embodiment will be described in detail. In this embodiment, as follows: Figure 1 As shown, Figure 1 The right side of this embodiment is the front side. An automatic bag-feeding machine according to this embodiment includes a storage bin 0-1, a picking unit 0-2, a temporary storage unit 0-3, a feeding unit 0-4, a buffer dispensing unit 0-5, a carton fixing unit 0-6, a conveying unit 0-7, and a frame 0-8. The conveying unit 0-7 is arranged below the frame 0-8, and the storage bin 0-1 is installed on the top of the frame 0-8. The picking unit 0-2 is arranged on the frame 0-8 directly below the storage bin 0-1. The temporary storage unit 0-3 is arranged between the storage bin 0-1 and the picking unit 0-2. The feeding unit 0-4 and the buffer dispensing unit 0-5 are arranged on the front and rear sides of the temporary storage unit 0-3, respectively. The carton fixing unit 0-6 is arranged on the top of the conveying unit 0-7.

[0043] It also includes a material detection photoelectric switch 1-1, an in-situ magnetic detection switch 1-2, a low-position detection magnetic switch 1-3, a middle-position detection magnetic switch 1-4, a high-position detection magnetic switch 1-5, a temporary storage area material detection photoelectric switch 1-6, an in-situ magnetic detection photoelectric switch 1-7, a buffer material detection photoelectric switch 1-8, a carton detection photoelectric switch 1-9, a position detection magnetic switch 1-10, a detection photoelectric switch 1-11, a full-track detection photoelectric switch 1-12, and a magnetic detection photoelectric switch 1-13. The material detection photoelectric switch 1-1 is installed inside the storage silo 0-1, and the in-situ magnetic detection switch 1-2 is installed inside the feeding unit 0-4. Magnetic detection switches 1-2 are installed in the material handling unit 0-2, and low-position detection magnetic switches 1-3, mid-position detection magnetic switches 1-4, and high-position detection magnetic switches 1-5 are installed in the material handling unit 0-2. The temporary storage unit 0-3 is equipped with a temporary storage area material detection photoelectric switch 1-6 and a magnetic detection photoelectric switch 1-13. The buffer delivery unit 0-5 is equipped with an in-situ magnetic detection photoelectric switch 1-7, a buffer material detection photoelectric switch 1-8, and a position detection magnetic switch 1-10. Above the conveying unit 0-7, from front to back, are a carton detection photoelectric switch 1-9, a detection photoelectric switch 1-11, and a full-track detection photoelectric switch 1-12.

[0044] The storage bin 0-1 includes a baffle 1, a guide rod 2, a stop block 3, a material-supporting cylinder 4, a material-supporting bearing seat 28, and a piston rod material-supporting frame 29. Two vertically arranged baffles 1 are symmetrically installed on the front and rear sides of the top of the frame 0-8. The bottom of the two baffles 1 and the top of the frame 0-8 together form a discharge port 0-9. Stop blocks 3 and guide rods 2 are installed on both the left and right sides of the discharge port 0-9. A material-supporting bearing seat 28 is installed on the frame 0-8 at the bottom of the guide rod 2. A piston rod material-supporting frame 29 is rotatably mounted on the material-supporting bearing seat 28. The end of the piston rod material-supporting frame 29 away from the discharge port 0-9 is hinged to one end of the material-supporting cylinder 4. The other end of the material-supporting cylinder 4 is hinged to one side of the guide rod 2 via a rotating shaft. Guide rod 2 is fixedly connected. The piston rod support frame 29 is located near the discharge port 0-9. Under the drive of the support cylinder 4, it swings up and down to lift and drop the tote bag. There are 4 blocks 3. The blocks 3 temporarily support the tote bag and only support the edge of the tote bag to prevent it from falling freely. When the picking unit 0-2 sucks in the tote bag, the tote bag will be slightly deformed under the suction force, which does not affect the picking unit 0-2 to pick up and pull the tote bag. The two baffles 1 and the two guide rods 2 together form a rectangular hopper. The bottom of the hopper is a hollow discharge port 0-9. A material detection photoelectric switch 1-1 is installed on the baffle 1 to detect whether the tote bag is inside the storage hopper 0-1.

[0045] The material handling unit 0-2 includes a material handling cylinder 5, a material handling cylinder fixing bracket 6, a guide rail 7, a guide slider bearing 8, a suction cup 9, a material handling support plate 10, a material handling support plate cylinder fixing plate 11, and a material handling support plate cylinder 12. The material handling cylinder 5 is mounted on the frame 0-8 via the material handling cylinder fixing bracket 6. The guide rail 7 is mounted on the frame 0-8, and the material handling cylinder 5 and the guide rail 7 are arranged vertically and parallel. The material handling support plate cylinder fixing plate 11 is slidably connected to the guide rail 7 via the guide slider bearing 8, and is also connected to the output end of the material handling cylinder 5. The material handling support plate cylinder 12 and the suction cups 9 are installed on the top of the material handling support plate cylinder fixing plate 11. There are four suction cups 9. The material handling support plate 10 is installed on the top output end of the material handling support plate cylinder 12. The material handling support plate 10 has four through holes 13, and each suction cup 9 is placed in each through hole 13. The picking cylinder 5 has three movement positions: low, middle, and high. When the picking cylinder 5 moves to the low, middle, and high positions, it triggers the low-position detection magnetic switch 1-3, the middle-position detection magnetic switch 1-4, and the high-position detection magnetic switch 1-5 located on the frame 0-8, respectively. The picking cylinder 5 drives the suction cup 9, the picking support plate 10, and the picking support plate cylinder 12 on the picking support plate cylinder fixing plate 11 to achieve longitudinal up-and-down reciprocating motion. The picking support plate cylinder 12 drives the picking support plate 10 to achieve longitudinal up-and-down reciprocating motion. At the same time, due to the setting of the suction cup 9 in the through hole 13, when the picking support plate 10 moves up and down, the suction cup 9 changes position at the top and bottom of the picking support plate 10. When the suction cup 9 needs to pick up the tote bag, the suction cup 9 is located above the picking support plate 10. When the tote bag is picked up, the suction cup 9 is located below the picking support plate 10, so that the suction cup 9 is completely separated from the tote bag.

[0046] The temporary storage unit 0-3 includes a material temporary storage fixing frame 14, which is fixedly installed below the discharge port 0-9. The tote bag separated from the suction cup 9 will fall onto the material temporary storage fixing frame 14. The material temporary storage fixing frame 14 is equipped with a temporary storage area material detection photoelectric switch 1-6 and a magnetic detection photoelectric switch 1-13. The temporary storage area material detection photoelectric switch 1-6 is used to detect whether the tote bag has fallen onto the material temporary storage fixing frame 14. At the same time, the magnetic detection photoelectric switch 1-13 is activated to count and detect the number of tote bags pushed by the feeding unit 0-4 to the buffer delivery unit 0-5. In this embodiment, every 3 times is a cycle.

[0047] The feeding unit 0-4 includes a feeding cylinder 15, a sliding guide needle roller bearing 16, a sliding guide shaft 17, and a feeding stop rod 18. The feeding cylinder 15 and the sliding guide shaft 17 are both horizontally mounted on the frame 0-8. The feeding stop rod 18 is slidably connected to the sliding guide shaft 17 through the sliding guide needle roller bearing 16. At the same time, the feeding stop rod 18 is connected to the feeding cylinder 15. The feeding cylinder 15 drives the feeding stop rod 18 to reciprocate, thereby pushing the handbags that fall on the material temporary storage fixing rack 14 into the buffer delivery unit 0-5 and then resetting. When the feeding cylinder 15 moves to the high position, it triggers the aforementioned magnetic detection photoelectric switch 1-13.

[0048] The buffer dispensing unit 0-5 includes a buffer dispensing cylinder 19, a material temporary storage bracket 20, and a temporary storage bracket fixing frame 21. The temporary storage bracket fixing frame 21 is fixedly installed on the frame 0-8. The buffer dispensing cylinder 19 is fixedly installed on the temporary storage bracket fixing frame 21. One end of the material temporary storage bracket 20 is hinged to the bottom of the temporary storage bracket fixing frame 21. The output end of the buffer dispensing cylinder 19 is hinged to the material temporary storage bracket 20. The tote bags pushed by the feeding stop 18 automatically fall on the top of the material temporary storage bracket 20. When a certain number accumulates, such as 3 bags... When the buffer release cylinder 19 is activated, it causes the material temporary storage bracket 20 to flip downwards, causing the tote bags on the material temporary storage bracket 20 to automatically fall into the carton on the bottom conveyor unit 0-7 under the action of the tilt angle. When the buffer release cylinder 19 is in the original position, it triggers the original position magnetic detection photoelectric switch 1-7 located on the temporary storage bracket fixing frame 21. When the buffer release cylinder 19 is activated to the high position, it triggers the position detection magnetic switch 1-10 located on the temporary storage bracket fixing frame 21. The material temporary storage bracket 20 is equipped with a buffer material detection photoelectric switch 1-8.

[0049] The conveying units 0-7 are conventional conveyor belt structures, including a conveyor frame, a drive pulley, a driven pulley, a conveyor belt, and a drive motor. The drive pulley and driven pulley are rotatably mounted on the left and right ends of the conveyor frame and are connected through the conveyor belt. The drive motor is fixedly mounted on the conveyor frame, and its output end is fixedly connected to the drive pulley. The drive motor drives the drive pulley to rotate. Multiple cartons are placed side by side on the conveyor belt, and the drive pulley drives the conveyor belt to achieve transmission.

[0050] The carton fixing unit 0-6 includes a first clamping cylinder 22, a second clamping cylinder 24, and a carton fixing guide bracket 23. The carton fixing guide bracket 23 is symmetrically installed on the left and right sides of the top of the conveying unit 0-7. The first clamping cylinder 22 is symmetrically installed on the left and right sides of the top of the conveying unit 0-7, and is located below the buffer delivery unit 0-5. The second clamping cylinder 24 is symmetrically installed on the left and right sides of the top of the conveying unit 0-7, and is located behind the first clamping cylinder 22. Simultaneous operation of the two first clamping cylinders 22 enables clamping action, clamping the front carton; simultaneous operation of the two second clamping cylinders 24 enables clamping action, clamping the rear carton. The first clamping cylinder 22 is located in front of the second clamping cylinder 24.

[0051] The carton fixing guide bracket 23 includes a guide plate 25, an adjusting shaft 26, and a locking seat 27. One end of the adjusting shaft 26 is installed on the left and right sides of the top of the conveying unit 0-7 through the locking seat 27, and the other end of the adjusting shaft 26 is installed with the guide plate 25. The guide plate 25 is vertically arranged. The locking seat 27 includes a base and a locking bolt. The base is fixedly installed on the conveying unit 0-7, and a hole is opened on the base. After the adjusting shaft 26 passes into the hole on the base, it is tightened and locked by the locking bolt, so that the distance between the two symmetrical guide plates 25 can be adjusted to accommodate cartons of different widths. This prevents the cartons from slipping and also limits their movement, so that the first clamping cylinder 22 and the second clamping cylinder 24 can accurately clamp the left and right sides of the cartons.

[0052] It also includes a main controller and a touch screen installed on racks 0-8. The main controller is a MITSUBISHI FX1N-40MR PLC, and the whole machine operation program is written using GX Works2 software to control the bag feeding process. It communicates with the touch screen using an RS232DB 9-pin to 8-pin round port data cable. The touch screen is a Wenview MT6070iH touch screen, and the touch screen program is written using EB8000 Project Manager software to control the whole machine operation, fault information display, and production capacity counting.

[0053] Specific Implementation Method Two: Combining Figures 1-9 This embodiment describes an automatic bag-dispensing method based on specific embodiment one, comprising:

[0054] S1, Place the tote bag into the storage bin 0-1 and ensure that the material detection photoelectric switch 1-1 detects the tote bag;

[0055] S2, the feeding cylinder 15 of the feeding unit 0-4 is triggered by the in-situ magnetic detection switch 1-2. After the start button is pressed, the picking cylinder 5 in the picking unit 0-2 is activated. When the picking cylinder 5 moves to the middle position, the middle position detection magnetic switch 1-4 is triggered, and the picking support plate cylinder 12 is activated, driving the picking support plate 10 from the high position to the low position. At the same time, the material lifting cylinder 4 of the storage bin 0-1 is activated, lifting the tote bag in the storage bin 0-1. The material detection photoelectric switch 1-1 is set in the space between 7cm and 500cm in the storage bin 0-1. Therefore, the height of the tote bag in the storage bin 0-1 must be higher than 7cm for the suction cup 9 to work normally. At the same time, to prevent the storage bin 0-1 from being too full and the top material from putting too much pressure on the bottom material, resulting in failure to pick up the tote bag, the upper limit height is set to 500cm.

[0056] S3, the vacuum generator connected to suction cup 9 operates. When suction cup 9 is in a vacuum state, the material-picking cylinder 5 moves to the high position, triggering the high-position detection magnetic switch. Simultaneously, the negative pressure of suction cup 9 is not less than 2.0 MPa. After maintaining this position for 0.7 seconds, the material-picking cylinder 5 resets and moves downwards. When it reaches the middle position, the middle-position detection magnetic switch 1-4 is triggered again, causing the material-picking support plate cylinder 12 to operate again, moving the material-picking support plate 10 from the low position to the high position. Simultaneously, the material-supporting cylinder 4 of the storage bin resets, causing the carrying bag to fall naturally from the discharge port 0-9. The vacuum generator resets, disengaging the vacuum of suction cup 9, and the carrying bag falls onto the material temporary storage fixing frame 14 in temporary storage unit 0-3.

[0057] S4, when the material-picking cylinder 5 moves to the low position, the low-position detection magnetic switch 1-3 is triggered, and the trigger signal of the low-position detection magnetic switch 1-3 is sent to the feeding unit 0-4. When the feeding unit 0-4 receives the action signal, the temporary storage area material detection photoelectric switch 1-6 on the temporary storage fixing frame 14 is triggered. If the temporary storage area material detection photoelectric switch 1-6 does not detect the bag, it issues an alarm signal indicating that the material picking has failed. If the temporary storage area material detection photoelectric switch 1-6 detects the bag, the feeding cylinder 15 moves to push the bag to the buffer delivery unit 0-5. When the feeding cylinder 15 moves to the high position, it triggers the magnetic detection photoelectric switch 1-13.

When the carton is below the buffer delivery unit 0-5, the carton detection photoelectric switch 1-9 is triggered, and the first clamping cylinder 22 and the second clamping cylinder 24 move in opposite directions at the same time, clamping the carton at the position of the first clamping cylinder 22. The first clamping cylinder 22 and the second clamping cylinder 24 move at the same time to prevent the two cartons from being connected together. The second carton is empty because no bag is delivered.

[0060] S7, the buffer dispensing cylinder 19 of buffer dispensing unit 0-5 is activated. When the buffer dispensing cylinder 19 is activated to the high position, the position detection magnetic switch 1-10 is triggered.

The buffer dispensing cylinder 19 is reset, and the original position magnetic detection photoelectric switch 1-7 is triggered. At this time, the handbags have been put into the carton.

[0061] S8, after the buffer delivery cylinder 19 triggers the in-situ magnetic detection photoelectric switch 1-7, the first clamping cylinder 22 is reset, and the carton is driven to the next station by the power of the conveying unit 0-7;

[0062] S9, when the carton leaves the detection photoelectric switch 1-11, the second clamping cylinder 24 is reset, and the next carton will be transported to the position of the first clamping cylinder 22. The carton detection photoelectric switch 1-9 is triggered, and the first clamping cylinder 22 and the second clamping cylinder 24 act simultaneously. The front carton is clamped by the first clamping cylinder 22. When the buffer delivery unit 0-5 has buffered three tote bags, the next delivery is performed.

[0063] S10, when the carton enters the next station, triggering the full-track detection photoelectric switch 1-12, the carton detection photoelectric switch 1-9 detects the carton on the back side, the first clamping cylinder 22 and the second clamping cylinder 24 act simultaneously, the buffering and dispensing unit 0-5's buffering and dispensing cylinder 19, after dispensing three tote bags according to the dispensing conditions, will enter a pause state, that is, the feeding cylinder 15 remains in the reset state, the in-situ detection magnetic switch 1-2 is triggered, at this time the picking cylinder 5 will continue to work once, the buffering and dispensing unit 0-5 buffers three tote bags, and the temporary storage unit 0-3 stores one tote bag, saving three feeding cylinder actions and one picking cylinder action. When the carton leaves the full-track detection photoelectric switch 1-12, the first clamping cylinder 22 automatically resets and continues to run automatically, completing the automatic dispensing process of the tote bags.
