Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher production, specifically to an automatic packing machine. Background Technology

[0002] After fire extinguishers are manufactured and undergo labeling and other processing, they need to be packed. Traditional fire extinguisher packing operations are mostly done manually, including placing the fire extinguishers in boxes and sealing them. Generally, only auxiliary equipment is used to assist in the transportation of the fire extinguishers and the packed products. The efficiency of fire extinguisher packing operations is relatively low, and the labor intensity of personnel is relatively high.

[0003] Chinese utility model patent application number 202021981421.4 was applied for and granted by the applicant on September 11, 2020. This patent provides a fire extinguisher packing system that automates the packing process, reducing labor intensity and improving efficiency. However, in practical use, the applicant found the following problems with this patent: 1. It is not convenient to use with existing fire extinguisher production equipment, requiring manual labor or related equipment to transfer the fire extinguishers to the feeding mechanism, affecting production efficiency; 2. When packing fire extinguishers, generally two fire extinguishers are placed side-by-side on each layer. To ensure packing efficiency, the gripping component typically grabs two fire extinguishers simultaneously. The spacing between adjacent fire extinguishers before and after packing varies, requiring frequent adjustment of the spacing between the two gripping parts of the gripping component. The patent uses a rodless cylinder for adjustment, but frequent operation over a long period causes changes in the cylinder's accuracy, requiring frequent maintenance and repair, and incurring relatively high costs. To address the aforementioned problems, this utility model provides an automatic packing device for fire extinguishers. Utility Model Content

The first stop and the second stop are disposed above the first conveying mechanism. The actuating part of the positioning drive is connected to the second stop, and the positioning drive drives the second stop to reciprocate between the positioning stop position and the standby clearance position. When the second stop is in the positioning stop position, the first stop and the second stop are distributed along the conveying direction, and a packing positioning area is formed between the first stop and the second stop on the conveying surface of the first conveying mechanism.

[0011] As an optional technical solution of this utility model, a second conveying mechanism is provided at the end of the first conveying mechanism. The first conveying mechanism transfers the packaged box to the second conveying mechanism, and the second conveying mechanism drives the packaged box through the accessory packing station, where an accessory box is provided.

[0012] As an optional technical solution of this utility model, it also includes a box sealing and positioning mechanism. The box sealing and positioning mechanism includes a straightening module, a positioning module and two sets of roller conveyors. The two roller conveyors are arranged side by side and are connected to the conveying end of the second conveying mechanism. A first accommodating gap is reserved between the two roller conveyors. A second accommodating gap is reserved between adjacent rollers of each roller conveyor.

The alignment module includes a pallet holder, a rotary drive, and a lifting drive. The rotating part of the rotary drive is connected to the pallet holder, and the rotary drive is connected to the lifting part of the lifting drive and is driven by the lifting drive to move up and down between the alignment preparation position and the alignment standby position. When the rotary drive is in the alignment standby position, the pallet holder is within the pallet holder accommodating area.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figures 1-6 As shown, an automatic case packing machine includes a bottle gripping mechanism 1, a moving mechanism 2, a lifting mechanism 3, and a case packing operating table. The bottle gripping mechanism 1 is driven by the moving mechanism 2 to move back and forth between the bottle gripping station and the bottle packing station. When the bottle gripping mechanism 1 is at the bottle gripping station, it grips fire extinguisher bottles. When the bottle gripping mechanism 1 is at the bottle packing station, it places the fire extinguisher bottles to achieve case packing. The bottle-grabbing station can be set at the discharge station of the fire extinguisher production equipment. The fire extinguisher production equipment is equipped with a lifting mechanism at the bottle-grabbing station. The fire extinguisher production equipment transports the produced fire extinguisher bottles to the bottle-grabbing station. When the bottle-grabbing mechanism 1 moves to the bottle-grabbing station, the lifting mechanism lifts the fire extinguisher bottle at the bottle-grabbing station to a height suitable for the bottle-grabbing mechanism 1 to grab. The bottle-grabbing mechanism 1 grabs the fire extinguisher bottle. The lifting mechanism can be a vertically driven cylinder or a motor-driven module. The boxing operation platform is set at the bottle-filling station. The packaging box is positioned on the boxing operation platform. The height of the boxing operation platform is adjusted by the lifting mechanism 3 so as to cooperate with the bottle-grabbing mechanism 1 to achieve the boxing of fire extinguishers at the bottle-filling station. The lifting mechanism 3 is a vertically set cylinder or a vertically driven motor-driven module.

[0020] Please see Figures 1-4 The moving mechanism 2 includes a moving frame and a moving drive module. The moving drive module adopts driving components in the form of cylinders, motor drive modules, etc. The moving drive module is installed on the moving frame and is used to drive the bottle gripping mechanism 1 to move laterally.

[0021] The bottle gripping mechanism 1 includes a bottle gripping component, a bottle rotating drive component 11, an elastic support component 12, and a limiting support component 13. The bottle rotating drive component 11 is a rotary drive component in the form of a geared motor, a rotary cylinder, etc. The rotary drive component 13 is connected to the moving part of the moving mechanism 2. The rotating part of the rotary drive component 13 is provided with a bottle rotating base. The bottom end face or side end face of the bottle rotating base is its mounting end face. The mounting end face of the bottle rotating base is provided with two mounting baffles. A mounting shaft is provided between the two mounting baffles. There are two bottle gripping components, both of which are set on the mounting shaft. The two bottle gripping components can move along the mounting shaft to adjust their respective positions and the distance between them. The elastic support component 12 is connected to the two bottle gripping components. The elastic top support 12 supports the two bottle-grabbing parts, causing them to abut against the mounting baffles on their respective sides. When the two bottle-grabbing parts abut against the mounting baffles on their respective sides, the distance between the bottle-grabbing parts of the two bottle-grabbing parts is exactly the same as the distance between adjacent fire extinguisher bottles at the bottle-grabbing station. When the bottle-grabbing mechanism 1 is at the bottle-grabbing station, after the bottle-rotating drive 11 adjusts the position of the two bottle-grabbing parts circumferentially, the bottle-grabbing mechanism 1 can simultaneously grab two fire extinguisher bottles. After grabbing the fire extinguisher bottles, the bottle-rotating drive 11 adjusts the position of the two bottle-grabbing parts circumferentially again, so that the two grabbed fire extinguisher bottles are in a suitable orientation for packing, and the mounting shaft is parallel to the moving direction of the bottle-grabbing mechanism 1.

[0022] The limiting support 13 is set at the bottling station. The limiting support 13 can be installed on the moving frame of the moving mechanism 2. When the bottle grabbing mechanism 1 moves to a certain position towards the bottling station, the top support of the limiting support 13 abuts against the bottle grabbing part in front of the moving direction. When the bottle grabbing mechanism 1 continues to move towards the bottling station, the bottle grabbing part in front of the moving direction moves closer to the other bottle grabbing part along the installation axis due to the obstruction of the limiting support 13. The two bottle grabbing parts are supported by the elastic support 12 and move closer to each other. When the bottle rotating mechanism moves to the bottling station, the fire extinguisher bottle grabbed by the two bottle grabbing parts is just at a suitable spacing for packing. At this time, the lifting mechanism 3 drives the packing platform and the packaging box on the packing platform to rise, so that the two fire extinguisher bottles grabbed by the bottle grabbing mechanism 1 enter the packaging box. Then the bottle grabbing part releases the fire extinguisher bottles to realize the packing of the fire extinguisher bottles. Then the lifting mechanism 3 drives the packing platform to fall, and the moving mechanism 2 drives the bottle grabbing mechanism 1 to grab the fire extinguisher bottles again at the bottle grabbing station.

[0023] The rotating bottle drive 11 drives the bottle-grabbing base 14 to rotate 180°, adjusting the orientation of the grasped fire extinguisher bottle so that it can be packed in the desired orientation. Taking packing two layers of fire extinguishers into a box as an example, after the first layer of two fire extinguishers is placed into the box, the bottle-grabbing mechanism 1 moves to the bottle-grabbing station to grab the fire extinguisher bottle. After grabbing the fire extinguisher bottle, the rotating bottle drive 11 drives the bottle-grabbing base 14 to rotate 180°. Then, the moving mechanism 2 moves the bottle-grabbing mechanism 1 to the bottle-packing station, and the lifting mechanism 3 lifts the packing platform to complete the packing. The two layers of fire extinguishers in the box face opposite directions to meet the packing requirements. When packing the fire extinguishers, the lifting mechanism 3 lifts the packing platform to a suitable height so that the fire extinguisher bottle can be directly placed into the box after the bottle-grabbing mechanism releases it.

[0024] As an optional implementation, the position of the limiting support 13 is adjustable in the moving direction of the bottle-grabbing mechanism 1, so that when the bottle-grabbing mechanism 1 is at the bottle-filling station, the limiting support 13 adjusts the two fire extinguisher bottles grasped by the bottle-grabbing mechanism 1 to the optimal packing distance. As a specific example, the limiting support 13 is a screw rod, which is installed on the moving frame by a threaded installation. The limiting support rod is set along the moving direction of the bottle-grabbing mechanism 1, and its position is adjusted by rotation.

[0025] In a preferred embodiment, at least two mounting shafts are provided between the two mounting baffles. These shafts are parallel to each other, and the bottle-gripping component is connected to each shaft. The elastic support component 12 is a support spring, and a support spring is provided on each mounting shaft between the two support components. The two ends of the support spring abut against the two bottle-gripping components respectively. The limiting support component 13 includes at least two screws, which are parallel to each other and can be adjusted axially. Support clearance holes are provided on the mounting baffles corresponding to the positions of the screws. When the bottle-gripping mechanism 1 moves to a certain position towards the filling station, each screw passes through the corresponding support clearance hole and abuts against the bottle-gripping component. The bottle-gripping component is installed in cooperation with at least two mounting shafts and adjusted in cooperation with at least two screws, which improves the stability of the device and prevents the bottle-filling effect from being affected by the deflection of the bottle-gripping component.

[0026] The bottle-gripping component includes a bottle-gripping base 14, a suction cup 16 mounting plate 15, and suction cups 16. The bottle-gripping base 14 has a plate-like structure and is equipped with linear bearings. Each linear bearing is mounted on a mounting shaft, allowing the bottle-gripping base 14 to be mounted on a rotating bottle base. The suction cup 16 mounting plate 15 is located at the bottom of the bottle-gripping base 14 and has several suction cups 16. The suction cups 16 are industrial suction cup components used in the prior art. Multiple suction cups 16, in conjunction with a matching negative pressure device, can achieve the gripping and releasing of fire extinguisher bottles. For details, please refer to [link / reference]. Figure 3 and Figure 4The suction cup 16 mounting plate 15 is a tile-shaped arc plate. The suction cup 16 mounting plate 15 is installed at the bottom end of the bottle gripping base 14 by bolts. Several suction cups 16 are distributed on the suction cup 16 mounting plate 15. The suction end of each suction cup 16 is on the inner arc surface of the suction cup 16 mounting plate 15. Preferably, the suction cups 16 are arranged in multiple rows along the axial direction of the arc surface of the suction cup 16 mounting plate 15 to achieve a better gripping effect.

[0027] Please see Figure 1 , Figure 2 The packing operation table includes a first conveying mechanism 4, which is a belt conveyor or other existing conveying equipment. The conveying surface of the first conveying mechanism 4 is the operating surface of the packing operation table. The first conveying mechanism 4 is located in the lifting part of the lifting mechanism 3 and is driven by the lifting mechanism 3 for lifting and adjustment. A packaging box positioning mechanism 5 is provided on the conveying surface of the first conveying mechanism 4. The packaging box positioning mechanism 5 is used to position the packaging box in a designated position suitable for the bottle gripping mechanism 1 to pack.

[0028] The packaging box positioning mechanism 5 includes a first stop 51, a second stop 52, and a positioning drive 53. The positioning drive 53 can be a telescopic component in the form of a cylinder, hydraulic cylinder, or electric push rod, or it can be a linear motion module driven by a motor. The positioning drive 53 is connected to the body of the first conveying mechanism 4. Both the first stop 51 and the second stop 52 are located above the first conveying mechanism 4. The first stop 51 is connected to the body of the first conveying mechanism 4, and the second stop 52 is connected to the actuating part of the positioning drive 53. The second stop 52 is driven by the positioning drive 53. The first conveying mechanism 4 moves between the positioning stop position and the standby avoidance position. When the second stop 52 is in the positioning stop position, the first stop 51 and the second stop 52 are distributed along the conveying direction. A boxing positioning area is formed on the conveying surface of the first conveying mechanism 4 between the first stop 51 and the second stop 52. The first stop 51 and the second stop 52 cooperate to position the box in the boxing positioning area to a designated position suitable for the bottle gripping mechanism 1 to pack. When the bottle gripping mechanism 1 is in the bottle filling station, the lifting mechanism 3 drives the first conveying mechanism 4 to lift to a suitable height. In cooperation with the bottle gripping mechanism 1, the fire extinguisher bottles can be boxed. When the first stop 51 is in the standby avoidance position, the first stop 51 avoids the side position of the box to avoid affecting the first conveying mechanism 4 to transport the box.

[0029] Please see Figure 1The first stop 51 is a flat vertical plate, and the second stop 52 is an L-shaped vertical plate. The second stop 52 is moved by the positioning drive 53, and its moving direction is perpendicular to the conveying direction of the first conveying mechanism 4. When the second stop 52 is in the positioning stop position, the square area enclosed by the first stop 51 and the second stop 52 is the packaging box positioning area. The packaging box is placed in the packaging positioning area, and the three outer end faces of the packaging box are respectively attached to the L-shaped inner end faces of the first stop 51 and the second stop 52, thereby realizing the alignment of the packaging box.

[0030] In some embodiments, the positioning drive can adjust the installation position along the transport direction of the first transport mechanism 4 so that the packaging box positioning mechanism 5 can adapt to the packaging and processing of fire extinguisher bottles of various sizes.

[0031] As an optional implementation, the automatic box packer in this embodiment also includes a second conveying mechanism. The second conveying mechanism is a roller conveyor, belt conveyor, or other existing technology conveying equipment. The second conveying mechanism is located at the end of the conveying of the first conveying mechanism 4. After the packaging box on the first conveying mechanism 4 is packed, when the first conveying mechanism 4 is adjusted to a height that matches the second conveying mechanism, the first conveying mechanism 4 connects with the second conveying mechanism and the first conveying mechanism 4 transfers the packaging box to the second conveying mechanism. The second conveying mechanism drives the packed packaging box through the accessory packing station. The accessory packing station is provided with an accessory box 41, which is used to place the accessories required for the fire extinguisher. The accessories in the accessory box 41 can be packed into the packaging box by manual packing or with the assistance of equipment such as a robotic arm.

[0032] As a further embodiment, the automatic carton packer of this embodiment also includes a sealing and positioning mechanism 6. The sealing and positioning mechanism 6 is used to adjust the position and orientation of the packaging box so that the sealing equipment can seal the packaging box in subsequent processes. Please refer to... Figure 1 , Figure 2 , Figure 5 and Figure 6 The sealing and positioning mechanism 6 includes a straightening module, a positioning module, and two sets of roller conveyors 61. The two roller conveyors 61 are used to transport the packaging box. During the process of the two roller conveyors 61 cooperating to transport the packaging box, the positioning module adjusts the packaging box to the position of the corresponding straightening module, the straightening module adjusts the orientation of the packaging box, and the roller conveyors 61 transport the packaging box to the subsequent sealing equipment in a specific orientation state.

[0033] Two roller conveyor components 61 are arranged side by side, and both are connected to the second conveying mechanism. When the second conveying mechanism is a roller conveyor, the two roller conveyor components 61 and the second conveying mechanism can share drive components, machine body, etc. Figure 1 , Figure 2 and Figure 5The diagram shows a specific example of two roller conveyors 61 sharing a drive component, body, and other components with the second conveying mechanism. A first accommodating gap is reserved between the two roller conveyors 61, and a second accommodating gap is reserved between adjacent rollers of each roller conveyor 61. The first accommodating gap and each of the second accommodating gaps communicate to form a pallet rack accommodating area. At least one of the two roller conveyors 61 has a second accommodating gap facing each other, so that the pallet rack accommodating area is cross-shaped at least at two facing second accommodating gaps.

[0034] The alignment module includes a tray frame 62, a rotary drive component 63, and a lifting drive component 64. The lifting drive component 64 is preferably a vertically positioned cylinder, installed below the tray frame's accommodating area. The lifting part of the lifting drive component 64 is equipped with the rotary drive component 63. The tray frame 62 is positioned above the tray frame's accommodating area. The rotating part of the rotary drive component 63 extends into the tray frame's accommodating area and connects to the tray frame 62. The lifting drive component 64 drives the rotary drive component 63 to move vertically between an alignment preparation position and an alignment standby position. The tray frame 62 is a cross-shaped tray. When component 63 is in the orientation standby position, the tray frame 62 is in the tray frame receiving area. The tray frame 62 is embedded in the cross-shaped part of the tray frame receiving area. The upper edge of the tray frame 62 is lower than the conveying surface of the roller conveyor 61 to avoid affecting the conveying of the package on the roller conveyor 61. When the rotary drive component 63 is in the orientation preparation position, the tray frame 62 is raised above the tray receiving slot and the package conveyed above the tray frame 62 is lifted. At this time, the lower edge of the tray frame 62 is higher than the conveying surface of the roller conveyor 61. The rotary drive component 63 corrects the orientation of the package by driving the tray frame 62 to rotate.

[0035] To prevent interference between the pallet holder 62 and the roller conveyor 61 when the rotary drive 63 is in the aligning standby position, the rotary drive 63 rotates the pallet holder 62 by 90°. Each time the rotary drive 63 stops, the pallet holder 62 aligns with the cross-shaped portion of the pallet holder receiving area. Please refer to... Figure 5 , Figure 6 As a specific example of the rotary drive component 63, the rotary drive component 63 includes a bearing housing, a rotating rod, and a rotary telescopic component. The bearing housing is disposed in the lifting part of the lifting drive component 64. The rotating rod is connected to the bearing housing and rotates relative to the bearing housing. The rotating rod is vertically arranged. The pallet frame 62 is connected to the top end of the rotating rod. A force arm is provided on the rotating rod. The lifting part of the lifting drive component 64 is also provided with a support. The rotary telescopic component is a telescopic component in the form of a cylinder, electric push rod, etc. The rotary telescopic component is connected to the support and rotates relative to the support. The telescopic part of the rotary telescopic component is rotatably connected to the force arm. The telescopic movement of the rotary telescopic component can drive the rotating rod to rotate through the force arm, thereby driving the pallet frame 62 to rotate. By restricting the extension and retraction of the rotary telescopic component, the pallet frame 62 has a 90° angular deflection when the rotary telescopic component is in the extended state and when the rotary telescopic component is in the retracted state.

[0036] The alignment module is located above the pallet rack accommodating area. The alignment module includes alignment push plates 65 and alignment telescopic components 66. Alignment push plates 65 are located on opposite sides above the pallet rack accommodating area. The area between the two alignment push plates 65 above the pallet rack accommodating area is the packaging box alignment area. The alignment telescopic component 66 is a telescopic component in the form of a cylinder or electric push rod. The alignment telescopic component 66 is installed on the body of the roller conveyor 61. The telescopic part of the alignment telescopic component 66 is connected to the alignment push plate 65. On the drive frame of the two alignment telescopic components 66, the two alignment push plates 65 move closer or further away from each other. When the packaging box is transported to the packaging box alignment area, the alignment module adjusts the position of the packaging box so that the packaging box falls above the pallet rack accommodating area suitable for being lifted by the pallet rack 62. At the same time, the two alignment push plates 65 can also adjust the orientation of the packaging box so that the alignment module can adjust the packaging box to an orientation suitable for subsequent sealing operations.

[0037] Please refer to it again. Figures 1-6 When packing fire extinguishers using the automatic packing machine of this embodiment, empty packing boxes are placed on the first conveying mechanism 4, and the packing box positioning mechanism 5 positions the packing boxes. The moving mechanism 2 drives the bottle-grabbing mechanism 1 to the bottle-grabbing station, where the fire extinguisher bottles are lifted to a suitable height for grabbing. Each grabbing component of the bottle-grabbing mechanism 1 grabs the fire extinguisher bottles. Then, the moving mechanism 2 drives the bottle-grabbing mechanism 1 to move towards the filling station. During the movement, under the action of the limiting support component 13, the two grabbed fire extinguisher bottles move closer to each other. When the bottle-grabbing mechanism 1 reaches the filling station, the two grabbed fire extinguisher bottles are at a suitable distance for packing. The lifting mechanism 3 then... The first conveying mechanism 4 is raised to load the grabbed fire extinguisher bottles into the packaging box. Then, the lifting mechanism 3 drives the first conveying mechanism 4 to descend. The moving mechanism 2 drives the bottle-grabbing mechanism 1 to grab two more fire extinguisher bottles at the bottle-grabbing station and rotate them 180°. The moving mechanism 2 then drives the bottle-grabbing mechanism 1 to move to the bottle-filling station. The lifting mechanism 3 drives the first conveying mechanism 4 to rise again to complete the boxing. Then, the lifting mechanism 3 drives the first conveying mechanism 4 to descend to a height that matches the second conveying mechanism. The second stop 52 of the packaging box positioning mechanism 5 moves to the standby clearance position so that the first conveying mechanism 4 can transport the boxed packaging box to the second conveying mechanism.

[0038] The packaging box is transported to the accessories packing station by the second conveying mechanism. After the necessary accessories for the fire extinguisher bottle are loaded into the packaging box, the second conveying mechanism transports the packaging box to the sealing and straightening mechanism 6. The packaging box is then transported to the packaging box straightening area by two sets of roller conveyors 61. The straightening components straighten the packaging box so that it is above the pallet rack 62. When it is necessary to adjust the orientation of the packaging box, the lifting drive 64 drives the rotary drive 63 from the straightening standby position to the straightening preparation position. The pallet rack 62 is then raised, lifting the packaging box. The rotary drive 63 drives the pallet rack 62 to rotate 90°.
