Description

Technical Field

[0001] This invention relates to the field of material transportation and stacking technology, specifically to an automated cement unloading device. Background Technology

[0002] On cement packaging production lines, traditional palletizing and unloading processes suffer from three major technical bottlenecks: difficulty in controlling dust pollution, lagging detection of packaging damage, and failure of mechanical clamping. In existing technologies, dust control mainly relies on large-scale dust removal equipment, which is energy-intensive and cannot specifically seal leakage sources. Damage detection often uses offline sampling or simple weighing methods, which are difficult to achieve real-time and accurate positioning. Furthermore, the clamping mechanism often causes packaging scratches and unstable gripping due to cement residue, requiring frequent manual cleaning. These problems result in low production efficiency, serious material waste, and a harsh working environment. Therefore, there is an urgent need to develop an automated cement unloading equipment that integrates intelligent sealing, dynamic damage monitoring, and self-cleaning clamping to achieve efficient, environmentally friendly, and intelligent production.

[0003] The published patent CN202410225857.7 discloses a fully automated bagged cement loading robot, including a conveyor belt mechanism, an electric guide rail base, a translation base, a robotic arm, and a control cabinet. The electric guide rail base is disposed on one side of the conveyor belt mechanism, the translation base is driven and disposed on the end face of the electric guide rail base, the robotic arm is fixedly mounted on the end face of the translation base, a mounting seat is mounted on the end of the robotic arm, and a loading and unloading mechanism is mounted on the lower end of the mounting seat. The control cabinet is fixedly disposed on the side wall of the electric guide rail base. This patent can ensure that the center of gravity of the bagged cement is near the center point of the cement bag during loading, improving the stability of the bagged cement after loading. It can also prevent the cement bags from being squeezed and bursting. Furthermore, it can remove damaged cement bags based on the weight and dust content of the cement bags, improving the quality of the cement bags leaving the factory. At the same time, it can minimize the escape of dust during the loading of bagged cement. However, this device is not convenient for detecting and removing damaged concrete bags. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated cement feeding device. This invention enables automatic detection of cement bag breakage and automatic protective measures in the event of significant damage.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an automated cement feeding device, comprising a hoisting frame, cement bags, a handling cylinder fixed to the top of the hoisting frame and used for fixed connection with a robotic arm, a tilting frame hinged to the bottom side of the hoisting frame, a handling clamp fixed to the tilting frame and used for clamping the cement bags, and a handling cylinder used for controlling the deflection of the tilting frame. A bag breakage detection device is provided on one side of the handling clamp, and the bag breakage detection device is used to detect whether the surface of the cement bag is damaged.

[0006] The bag-breaking detection device includes a bending swing plate and a detection plate. There are multiple transport clamps. After adjacent transport clamps contact the bottom of the cement bag, they tighten the surface of the cement bag.

[0007] The corner of the handling clamp is rotatably equipped with a bending swing plate, and a detection plate is set at the bottom of the cement bag on the bending swing plate. The detection plate contacts the taut surface of the cement bag under the force deflection of the bending swing plate.

[0008] The test plate applies pressure to the taut surface of the cement bag. If the surface of the cement bag is damaged, it will not be able to support the test plate.

[0009] According to the above technical solution, a push rod is fixedly connected to the bottom drive part of the conveying cylinder, and a swing plate is hinged inside the push rod. A waist-shaped groove is opened at the hinge of the swing plate. The other end of the swing plate is fixedly connected to the flipping frame. A squeezing cylinder is set at the position corresponding to the middle of the cement bag on the hoisting frame. The squeezing cylinder is used to squeeze the top of the cement bag.

[0010] According to the above technical solution, the bag breaking detection device includes a fixed detection block, a hinge platform one, and a hinge platform two. The hinge platform one and the hinge platform two are fixedly connected to one side of the handling clamp. The hinge platform two is located at the top of the hinge platform one. The bending swing plate is rotatably connected to the hinge platform one. A force application frame is hinged to the top of the bending swing plate. A waist-shaped groove two is opened on the force application frame. The waist-shaped groove two is hinged to the hinge platform two.

[0011] A spring is provided between the force-applying frame and the hinge platform, and the spring pulls the force-applying frame downward under normal conditions.

[0012] A fixed detection block is fixedly connected to the flipping frame, and a movable slider is slidably connected to the fixed detection block. The bottom of the movable slider contacts the top of the force application frame.

[0013] According to the above technical solution, the end of the detection plate away from the force application frame is hinged to a support platform. The top of the support platform is flat. The support platform is located in the middle of the gap of the handling clamp. The support platform is in contact with the bottom of the cement bag.

[0014] According to the above technical solution, the top of the hoisting frame is sealed, and filter screens are slidably inserted into the left and right ends of the top of the hoisting frame. Air washing devices are provided at the front and rear ends of the hoisting frame, and smoke and dust prevention devices are provided on the air washing devices. A sealing cloth is provided between the smoke and dust prevention devices.

[0015] The smoke and dust prevention device includes a gear, which is rotatably connected to both ends of the hoisting frame. At least three U-shaped support rods are rotatably sleeved on one side of the gear. A protruding drag block is fixedly connected to the side of the gear near the U-shaped support rods. A sealing cloth is sleeved on the outside of the U-shaped support rods.

[0016] According to the above technical solution, a guide rail is fixedly connected to the air washing device, a plurality of sliders are slidably connected to the guide rail, a slider is slidably connected to the middle of the guide rail, and a transfer cloth is fixedly connected to the sliders and sliders.

[0017] The top of the second slider is fixedly connected to a traction housing, and the bottom of the second slider is rotatably connected to a splicing plate. A second gear is fixedly connected to one side of the splicing plate, and the shaft of the second gear is lower than the shaft of the first gear.

[0018] Multiple male and female adhesive strips are fixedly connected to the adapter cloth, splicing plate, and sealing cloth one; the sealing cloth two is fixed to the adapter cloth, splicing plate, and sealing cloth one by means of the male and female adhesive strips.

[0019] A mop cylinder is fixedly connected to one side of the hoisting frame. A U-shaped rod is fixedly connected to the drive part of the mop cylinder. A limit frame is fixedly connected inside the traction housing. The U-shaped rod passes through the traction housing and the limit frame. A magnet and a synchronization plate are fixedly connected to one end of the U-shaped rod that passes through the traction housing. A double-sided rack is fixedly connected to the bottom of the synchronization plate. The double-sided rack is used to mesh with gear one and gear two. A limit ring is fixedly connected to the U-shaped rod. There is a gap between the limit ring and the traction housing.

[0020] According to the above technical solution, the air washing device includes an air guide shell, the interior of which is hollow and slidably connected to an air distribution frame. An air inlet and outlet hole is opened at the contact position between the air distribution frame and the bottom wall of the air guide shell. Multiple bent protrusions are bent on the air distribution frame. The bent protrusions and the bottom of the air guide shell form a dust storage bin. The dust storage bin is permeable at the position corresponding to the bent protrusions and is equipped with a filter screen.

[0021] According to the above technical solution, the bending protrusion and the air guide shell form a control air chamber. The two ends of the air guide shell are connected to an air inlet, and the side of the air guide shell near the control air chamber is connected to an air extraction port. The two sides of the air distribution frame are provided with ventilation holes. The number of ventilation holes on the side of the air distribution frame near the control air chamber is two, and one-way valves with opposite directions are installed in the ventilation holes.

[0022] This invention provides an automated cement feeding device. It has the following beneficial effects:

[0023] This invention utilizes a pneumatic cylinder to cause gear one and the splicing plate to flip downwards, and then unfolds the sealing cloth two under the support and limiting frame of the magnet. This wraps the damaged cement bag, and as the robotic arm moves, the cement bag is moved to the processing area. By directly removing the sealing cloth two and cooperating with the operation of the handling cylinder, the handling clamps open outwards, and the damaged cement bag, along with the sealing cloth two, is placed in this area. This solution uses a pneumatic push rod to quickly unfold the folded cloth, which can promptly seal the damaged parts of the cement bag, effectively prevent the spread of cement dust, significantly reduce dust pollution in the work area, protect worker health, and reduce cleaning and maintenance costs.

[0024] In this invention, when a cement bag is damaged, the detection plate, under the downward movement of the force-applying frame, causes the bending swing plate and the detection plate to deflect upward, and the movable slider in contact with the detection plate to move downward. This causes the value detected by the fixed detection block to exceed the threshold, and the feedback is sent to the robotic arm to control the robotic arm to stop working. The cement bag is divided into multiple areas by the handling clamps, and the tension changes of each local area are sensed in real time on the detection plate. When a certain area is damaged, the detection plate at that location will show obvious displacement due to the weakening of the bag tension, thereby determining whether the cement bag is damaged. Compared with laser detection, this method can detect smaller damage areas and has greater versatility.

[0025] This invention features a system where, after a cement bag is lowered, air is inflated into the air-conducting outer shell through an air inlet and discharged downwards through air inlet and outlet holes. This air is used to blow away floating dust on the top side of the handling clamps, preventing the deposited dust from hardening and scratching the surface of the cement bag after contact with water. Simultaneously, when the cement bag has a large opening and the dust prevention device and sealing cloth have already wrapped the lifting frame, air is drawn from the air-conducting outer shell through an air extraction port. The air chamber is controlled to slide under the negative pressure generated by the extraction until the air inlet and outlet holes align with the ash storage bin. The extracted gas passes through a bent, protruding filter, leaving the cement dust inside the lifting frame in the ash storage bin. This achieves the purpose of removing floating cement dust from the lifting frame. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Please see Figure 1-10An embodiment of the present invention is as follows: an automated cement feeding device, including a hoisting frame 1, a cement bag 3, a handling cylinder 2 fixed to the top of the hoisting frame 1 and used for fixed connection with a robotic arm, a tilting frame 5 hinged to the bottom side of the hoisting frame 1, a handling clamp 4 fixed to the tilting frame 5 and used for clamping the cement bag 3, and a handling cylinder 2 used for controlling the tilting frame 5 to deflect. A bag breakage detection device 6 is provided on one side of the handling clamp 4, and the bag breakage detection device 6 is used to detect whether the surface of the cement bag 3 is damaged.

[0039] The bag breaking detection device 6 includes a bending swing plate 602, a detection plate 604, and multiple handling clamps 4. After adjacent handling clamps 4 come into contact with the bottom of the cement bag 3, they tighten the surface of the cement bag 3.

[0040] A bending swing plate 602 is rotatably installed at the corner of the handling clamp 4. A detection plate 604 is installed at the bottom of the cement bag 3. The detection plate 604 contacts the taut surface of the cement bag 3 under the force deflection of the bending swing plate 602.

[0041] The detection plate 604 applies pressure to the taut surface of the cement bag 3. If the surface of the cement bag 3 is damaged, the surface of the cement bag 3 will not be able to support the detection plate 604.

[0042] Furthermore, the handling clamp 4 supports the cement bag 3, causing the cement bag 3 to form an arched protrusion under the support of the handling clamp 4.

[0043] Furthermore, there are two transport cylinders 2, and the transport cylinders 2 on the hoisting frame 1 can work separately, so that the hoisting frame 1 can hold two cement bags 3 at the same time.

[0044] In use, by applying a continuous force to one side of the bending swing plate 602, the detection plate 604 is made to adhere to the taut surface of the cement bag 3. When there is a tear on the surface of the cement bag 3, the surface tension of the cement bag 3 is broken, and the surface support of the cement bag 3 between the handling clamps 4 is reduced. At this time, the detection plate 604, supported by the bending swing plate 602, further squeezes the cement bag 3, which increases the bending angle of the bending swing plate 602. By detecting the increased value, the purpose of detecting whether the bottom surface of the cement bag 3 is damaged is achieved. At the same time, the bottom of the cement bag 3 is divided into multiple areas by the handling clamps 4, and each area is equipped with a bag breakage detection device 6. Therefore, the bag breakage detection device 6 can also detect small tears on the bottom of the cement bag 3.

[0045] A push rod 11 is fixedly connected to the bottom drive part of the handling cylinder 2. A swing plate 13 is hinged inside the push rod 11. A waist-shaped groove is opened at the hinge of the swing plate 13. The other end of the swing plate 13 is fixedly connected to the flipping frame 5. A squeezing cylinder 14 is set at the position corresponding to the middle of the cement bag 3 on the hoisting frame 1. The squeezing cylinder 14 is used to squeeze the top of the cement bag 3.

[0046] Furthermore, the swing plate 13 is slidably connected inside the push rod 11, and a limit block is provided at the end of the push rod 11. When the working part of the conveying cylinder 2 extends to the maximum stroke distance, the push rod 11 is flush with the swing plate 13.

[0047] Furthermore, the entire display plate 13 is bent.

[0048] In use, the working part of the handling cylinder 2 operates, driving the push rod 11 to move downward. At this time, the swing plate 13 deflects under the guidance of the waist-shaped groove, and applies a deflection force to the hinge of the flipping frame 5 and the lifting frame 1, thereby driving the handling clamp 4 to deflect in the opposite direction. At this time, the lifting frame 1 is lowered as a whole by the control of the robotic arm until it is located outside the cement bag 3 with the handling clamp 4. Then, the handling cylinder 2 is controlled to work in the opposite direction, so that the handling clamp 4 moves closer to each other. As the lifting frame 1 is raised as a whole by the control of the robotic arm, the cement bag 3 is grasped. When the lifting frame 1 is moved to the predetermined position by the control of the robotic arm, the limit of the cement bag 3 is released by the control of the handling cylinder 2 and the squeezing cylinder 14. At the same time, the squeezing cylinder 14 applies downward pressure to the cement bag 3, so that the cement bag 3 falls vertically to the predetermined position, thereby realizing the clamping and placement of the cement bag 3.

[0049] The bag breaking detection device 6 includes a fixed detection block 607, a hinge platform 1 601, and a hinge platform 2 610. The hinge platform 1 601 and the hinge platform 2 610 are fixedly connected to one side of the handling clamp 4. The hinge platform 2 610 is located on top of the hinge platform 1 601. The bending swing plate 602 is rotatably connected to the hinge platform 1 601. The top of the bending swing plate 602 is hinged to a force application frame 603. The force application frame 603 has a waist-shaped groove 2 608, which is hinged to the hinge platform 2 610.

[0050] A spring 605 is provided between the force application frame 603 and the hinge platform 601. Under normal conditions, the spring 605 pulls the force application frame 603 to move downward.

[0051] A fixed detection block 607 is fixedly connected to the flipping frame 5, and a movable slider 606 is slidably connected to the fixed detection block 607. The bottom of the movable slider 606 contacts the top of the force application frame 603.

[0052] Furthermore, a grating detection unit is provided on the fixed detection block 607, and a grating is engraved on the movable slider 606. When the cement bag 3 in the area of ​​the handling clamp 4 is damaged, the detection plate 604 deflects upward, the force frame 603 moves downward, and the movable slider 606 slides downward. By detecting the change in displacement through the fixed detection block 607, when the value exceeds a certain threshold, it can be confirmed that the surface of the cement bag 3 is damaged.

[0053] In use, when the handling clamp 4 is deflected towards the bottom of the cement bag 3, as the lifting frame 1 moves upward, the handling clamp 4 supports the cement bag 3 and tightens the cement bag 3. When the cement bag 3 is damaged, the detection plate 604 is pulled downward by the force application frame 603, causing the bending swing plate 602 and the detection plate 604 to deflect upward, and causing the movable slider 606 in contact with the detection plate 604 to move downward, so that the value detected by the fixed detection block 607 exceeds the threshold and is fed back to the robotic arm to control the robotic arm to stop working.

[0054] The end of the test plate 604 away from the force application frame 603 is hinged to a support platform 609. The top of the support platform 609 is flat. The support platform 609 is located in the middle of the gap of the handling clamp 4. The support platform 609 is in contact with the bottom of the cement bag 3.

[0055] In use, the support platform 609 is hinged to the detection plate 604. When the detection plate 604 deflects at a small angle, the top of the support platform 609 remains in contact with the surface of the cement bag 3 to ensure the stability of the support position.

[0056] The top of the hoisting frame 1 is sealed. Filter screens 10 are slidably inserted into the left and right ends of the top of the hoisting frame 1. Air washing devices 8 are installed at the front and rear ends of the hoisting frame 1. Smoke and dust prevention devices 7 are installed on the air washing devices 8. Sealing cloth 2 9 is installed between the smoke and dust prevention devices 7.

[0057] The smoke and dust prevention device 7 includes a gear 701, which is rotatably connected to both ends of the hoisting frame 1. At least three U-shaped support rods 702 are rotatably sleeved on one side of the gear 701. A protruding drag block 711 is fixedly connected to the side of the gear 701 near the U-shaped support rods 702. A sealing cloth 703 is sleeved on the outside of the U-shaped support rods 702.

[0058] Furthermore, the sealing of the hoisting frame 1 and the cooperation of the filter screen 10 prevent the spread of cement dust.

[0059] Furthermore, the rotating gear 701 causes the protruding drag block 711 to press the U-shaped support rod 702 upward and flip it over, folding the arched parts at both ends.

[0060] The sealing cloth 29 is detachably connected to the smoke and dust prevention device 7 via a snap-fit ​​structure.

[0061] When in use, if the values ​​detected by multiple fixed detection blocks 607 exceed the threshold, that is, the damage is too large and the cement leakage is serious, the entire equipment can be wrapped with dust prevention device 7 and sealing cloth 9 to prevent cement dust from spreading and affecting the working environment and the safety of the equipment.

[0062] A guide rail 706 is fixedly connected to the air washing device 8. Multiple sliders 707 are slidably connected to the guide rail 706. A slider 708 is slidably connected to the middle of the guide rail 706. A transfer cloth 705 is fixedly connected to the slider 708 and slider 707.

[0063] The top of slider 2 708 is fixedly connected to a traction housing 713, and the bottom of slider 2 708 is rotatably connected to a splicing plate 717. A gear 2 716 is fixedly connected to one side of the splicing plate 717, and the shaft of gear 2 716 is lower than the shaft of gear 1 701.

[0064] Multiple male and female adhesive strips 704 are fixedly connected to the adapter cloth 705, splicing plate 717, and sealing cloth 703. Sealing cloth 9 is fixed to the adapter cloth 705, splicing plate 717, and sealing cloth 703 through the male and female adhesive strips 704.

[0065] A mop cylinder 712 is fixedly connected to one side of the hoisting frame 1. A U-shaped rod is fixedly connected to the drive part of the mop cylinder 712. A limit frame 718 is fixedly connected inside the traction housing 713. The U-shaped rod passes through the traction housing 713 and the limit frame 718. A magnet 714 and a synchronization plate 709 are fixedly connected to one end of the U-shaped rod that passes through the traction housing 713. A double-sided rack 710 is fixedly connected to the bottom of the synchronization plate 709. The double-sided rack 710 is used to mesh with gear 1 701 and gear 2 716. A limit ring 715 is fixedly connected to the U-shaped rod. There is a gap between the limit ring 715 and the traction housing 713.

[0066] Furthermore, the slider 707, located near the gear 701, is fixedly connected to the guide rail 706.

[0067] Furthermore, when the various sliders 707 are attached, the adapter cloth 705 protrudes and bends outward.

[0068] Furthermore, there are two sliders 708, guide rails 706, and sealing cloth 9. The sealing cloth 9 covers the outside of sliders 707 and 708. When sliders 708 move away from each other, the sealing cloth 9 can be folded and stored.

[0069] Furthermore, the contact surfaces of the two splicing panels 717 are provided with magnetic metal.

[0070] In use, the operation of the mop cylinder 712 drives the magnet 714 to drag the limit frame 718, the traction housing 713, and the second slider 708 to slide under the guidance of the guide rail 706. When the second slider 708 pushes each first slider 707 to fit together until the second slider 708 can no longer slide on the guide rail 706, the magnet 714 disengages from the limit frame 718 under the operation of the traction housing 713. At this time, the synchronous plate 709 and the second slider 708 undergo relative displacement, causing the synchronous plate 709 to drive the double-sided rack 710 to mesh synchronously with the second gear 716 and the first gear 701. As the mop cylinder 712 operates, it drives the second gear 716 to mesh synchronously. Gear 1 701 rotates, causing sealing cloth 1 703 to fold upwards. Sealing cloth 2 9 is then lifted upwards after folding, avoiding any impact on the normal operation of the equipment. Through the reverse operation of the drag cylinder 712, gear 1 701 and splicing plate 717 first flip downwards, and the magnet 714 supports the limiting frame 718 to unfold sealing cloth 2 9, wrapping the damaged cement bag 3. As the robotic arm moves, the cement bag 3 is moved to the processing area. By directly removing sealing cloth 2 9, and in conjunction with the operation of the handling cylinder 2, the handling clamp 4 is opened outwards, and the damaged cement bag 3, along with sealing cloth 2 9, is placed in this area for convenient subsequent processing.

[0071] The air washing device 8 includes an air guide shell 801. The air guide shell 801 is hollow inside and slidably connected to an air distribution frame 803. An air inlet and outlet hole 807 is opened at the contact position between the air distribution frame 803 and the bottom wall of the air guide shell 801. Multiple bent protrusions 802 are bent on the air distribution frame 803. The bent protrusions 802 and the bottom of the air guide shell 801 form a dust storage bin 804. The dust storage bin 804 is breathable at the position corresponding to the bent protrusions 802 and is equipped with a filter screen.

[0072] The bent protrusion 802 and the air guide shell 801 form a control air chamber 808. The two ends of the air guide shell 801 are connected to the air inlet 805. The side of the air guide shell 801 near the control air chamber 808 is connected to the air outlet 806. The air distribution frame 803 has vent holes on both sides. The air distribution frame 803 near the control air chamber 808 has two vent holes, and one-way valves with opposite directions are installed in the vent holes.

[0073] Furthermore, the air inlet and outlet ports 807 are positioned corresponding to the positions of the handling clamps 4.

[0074] Furthermore, by using the one-way valve on the gas distribution frame 803, the air inlet 805 and air outlet 806 on one side of the control air chamber 808 are controlled to increase or decrease the air pressure in the air chamber 808 when it is filled or emptied, thereby controlling the gas distribution frame 803 to slide within the air guide shell 801.

[0075] When in use, after the cement bag 3 is placed down, air is inflated into the air guide shell 801 through the air inlet 805, and the air is discharged downward through the air inlet and outlet 807 to blow away the floating dust on the top side of the handling clamp 4, so as to prevent the deposited dust from hardening after getting wet and causing scratches on the surface of the cement bag 3.

[0076] When the cement bag 3 has a large hole, and the dust prevention device 7 and the sealing cloth 9 have wrapped the hoisting frame 1, air is drawn from the air guide shell 801 through the air extraction port 806. The air chamber 808 is controlled to drag the air distribution frame 803 to slide under the negative pressure generated by the air extraction until the air inlet and outlet 807 corresponds to the ash storage bin 804. The gas is then extracted and filtered by the bending protrusion 802, leaving the cement dust in the hoisting frame 1 in the ash storage bin 804. This achieves the purpose of removing the floating cement dust in the hoisting frame 1.

[0077] Working principle: The working part of the conveying cylinder 2 drives the push rod 11 to move downward. At this time, the swing plate 13 is deflected under the guidance of the waist-shaped groove 1, and a deflection force is applied to the hinge of the flipping frame 5 and the lifting frame 1. This causes the conveying clamp 4 to deflect in the opposite direction. At this time, the lifting frame 1 is lowered as a whole by the control of the robotic arm until it is located outside the cement bag 3 with the conveying clamp 4. Then, the conveying cylinder 2 is controlled to work in the opposite direction, so that the conveying clamp 4 moves closer to each other. As the lifting frame 1 is raised as a whole by the control of the robotic arm, the cement bag 3 is grasped. When the lifting frame 1 is moved to the predetermined position by the control of the robotic arm, the limit of the cement bag 3 is released by the control of the conveying cylinder 2 and the squeezing cylinder 14. At the same time, the squeezing cylinder 14 applies downward pressure to the cement bag 3, so that the cement bag 3 falls vertically to the predetermined position, thereby realizing the clamping and placement of the cement bag 3.
