Description

Technical Field

[0001] The present invention relates to the technical field of mattress production, and in particular to a bed core frame positioning device and method and a spring mattress production line. Background Art

[0002] Pocket spring mattresses are increasingly popular for their comfort, but the edges of pocket spring cores are prone to deformation and collapse. To improve the core's stability, they are often secured with a metal frame. Currently, the framing of pocket spring cores is typically done manually, using a handheld nail gun to secure the frame and spring string edges. Alternatively, the frame is manually positioned and initially secured, followed by a nailing process, resulting in a low level of automation. Summary of the Invention

[0057] Reference Figures 1 to 8 The bed core frame positioning device of the first embodiment of the present invention is used to fix the frame and the edge of the pocket spring bed core. The bed core frame positioning device includes a positioning mechanism 200, a feeding mechanism 100, a flipping mechanism 300 and a frame removal mechanism 400.

[0058] The positioning mechanism 200 includes a supporting platform 210, at least one fixing component 220, and at least one limiting component 230. The supporting platform 210 is used to support the bed core. The limiting component 230 and the supporting platform 210 can be movably arranged to be relatively close to or away from each other so that the frame fits the bed core. The limiting component 230 can be movably arranged to form a material receiving station and a positioning station. The limiting component 230 is suitable for receiving the frame at the material receiving station and for limiting the frame at the positioning station. The fixing component 220 includes at least one nail gun 223 and a drive assembly, and the drive assembly is used to drive the nail gun 223 to move. The positioning mechanism 200 sequentially performs the steps of adjusting the position of the frame and the bed core, positioning the frame, and fixing the frame, thereby improving the degree of automation of fixing the frame, effectively improving production efficiency, and reducing labor costs.

[0059] In some embodiments of the present invention, specific reference is made to Figure 1 The bed core frame positioning device also includes a loading mechanism 100, wherein the loading mechanism 100 is used to convey the frame, the carrying platform 210 is used to carry the bed core, and can be raised and lowered in the vertical direction, the limiting component 230 switches between the material receiving station and the positioning station, the limiting component 230 is suitable for receiving the frame at the material receiving station, the limiting component 230 is suitable for driving the frame to move during the switching movement, so that the frame and the bed core have a preset relative position relationship, the limiting component 230 is suitable for limiting the frame above the bed core at the positioning station, the carrying platform 210 is suitable for lifting the bed core and fitting the frame to the bed core, the fixing component 220 is actuated and used to fix the frame in a predetermined position on the bed core.

[0060] It is understood that the fixing member 220 is used to position the frame on the mattress core. Preferably, the nail gun 223 can be a C-shaped nail gun 223. When in use, the nail gun 223 clamps the frame and springs and starts nailing at the same time to fix the frame to the surface of the mattress core with pocket springs. In other embodiments, the nail gun 223 can also be replaced with a glue gun, welding gun, or other connecting component.

[0061] In some embodiments of the present invention, specific reference is made to Figure 1 The bed core frame positioning device further includes a frame removal mechanism 400, which is adapted to receive the frame delivered by the feeding mechanism 100 and deliver the frame to the limiting component 230. In some embodiments of the present invention, specifically referring to Figure 1 The bed core frame positioning device also includes a flipping mechanism 300, which is used to flip the bed core so that the upper and lower surfaces of the bed core are successively carried on the carrying platform 210. It can be understood that the bed core frame positioning device is realized by intermittent feeding of the feeding mechanism 100, automatic feeding, and the frame removal mechanism 400 is respectively connected to the feeding mechanism 100 and the positioning mechanism 200 to ensure the normal movement of the frame. After the frame is fixed to the upper surface of the bed core by the positioning mechanism 200, the upper and lower surfaces of the bed core are flipped by the flipping mechanism 300, and then the frame is fixed to the lower surface of the bed core by the positioning mechanism 200, so that the bed core frame positioning device has more functions, further improves the degree of automation of fixing the frame, effectively improves production efficiency, and reduces labor costs.

[0062] Preferably, with the positioning mechanism 200 as the layout reference, the feeding mechanism 100 is disposed on a first side of the positioning mechanism 200, the frame removal mechanism 400 is disposed between the feeding mechanism 100 and the positioning mechanism 200, and the flipping mechanism 300 is disposed on a second side of the positioning mechanism 200. The remaining sides of the positioning mechanism 200 can be used to connect to the upstream and downstream of the production line. The limiting component 230 and the fixing component 220 are disposed above the supporting platform 210. When the limiting component 230 is actuated to adjust the frame, the supporting platform 210 is lifted to position the frame with the bed core.

[0063] In some embodiments of the present invention, specific reference is made to Figure 2 and Figure 3 The frame removal mechanism 400 includes a grabbing assembly 410 and a transfer assembly 420. The transfer assembly 420 is adapted to drive the grabbing assembly 410 to move and form a receiving station and an output station. The grabbing assembly 410 switches between the receiving station and the output station. The grabbing assembly 410 is adapted to receive the frame delivered by the loading mechanism 100 at the receiving station. When the grabbing assembly 410 is at the output station, the frame is delivered to the limiting component 230. It is understandable that the method and path for the transfer assembly 420 to drive the grabbing assembly 410 are specifically designed to achieve the effect of driving the grabbing assembly 410 to dock with the loading mechanism 100 and the positioning mechanism 200 respectively through the transfer assembly 420.

[0064] In some embodiments, the gripping assembly 410 includes multiple hooks and cylinders. The hooks are L-shaped, and each cylinder is used to connect the hooks. When the cylinder is extended, each hook acts on each side of the frame. The hooks can form a closed space in space, preventing the frame from falling out during movement. In other embodiments, the gripping assembly 410 can also be configured as a clamping claw, suction cup, or other structural member for fixing.

[0065] In some embodiments, the transfer assembly 420 includes a sliding portion 421 and a swinging portion 422. The sliding portion 421 is used to drive the swinging portion 422 to slide, and the swinging portion 422 is used to drive the grabbing assembly 410 to swing. The sliding portion 421 and the swinging portion 422 cooperate to enable the grabbing assembly 410 to switch between the receiving station and the output station. The sliding portion 421 can be configured as a slide mechanism such as a linear slide rail or a linear module, and the swinging portion 422 can be configured as a transmission mechanism such as a connecting rod mechanism or a crank-connecting rod mechanism. The sliding portion 421 drives the swinging portion 422 and the grabbing assembly 410 to move in the horizontal direction, and the swinging portion 422 drives the grabbing assembly 410 to swing, thereby switching between the receiving station and the output station. The grabbing assembly 410 receives the vertically suspended frame at the receiving station, and is transported from the receiving station to the top of the receiving platform 210 by the sliding portion 421. The frame is then transported to the output station by the swinging portion 422 and placed horizontally on the limiting component 220. In order to ensure smooth docking between the grabbing assembly 410 and the positioning mechanism 200, a corresponding transition piece 430 can be set on the movement path of the frame. Figure 3 FIG. 4 is a schematic diagram of the frame-taking process, which shows the process in which the grabbing component 410 gradually swings after taking the frame until the frame is stably placed.

[0066] In some embodiments of the present invention, specific reference is made to Figure 8 The flipping mechanism 300 includes a flipping platform 310, a flipping assembly 320, a telescopic assembly 330 and a centering assembly 340. A first conveying assembly 311 is provided on the flipping platform 310, and a second conveying assembly is provided on the carrying platform 210. The second conveying assembly is docked with the first conveying assembly 311 so that the carrying platform 210 and the flipping platform 310 can transport the bed core respectively. The flipping assembly 320 is used to lift the bed core to achieve flipping, so that the bed core is tilted against the telescopic assembly 330 at a preset angle. The telescopic assembly 330 transports the bed core by telescoping and cooperating with the first conveying assembly 311, so that the bed core slides from the telescopic assembly 330 to the flipping platform 310. The centering assembly 340 is suitable for straightening the bed core and allowing the bed core to return to the carrying platform 210 in a preset posture under the action of the first conveying assembly 311. It is understood that the first conveying assembly 311 can rotate forward and reverse to input and output the bed core, and the turnover platform 310 is used to support the bed core for turnover. To this end, the turnover assembly 320, the telescopic assembly 330, and the centering assembly 340 are all disposed on the turnover platform 310. Preferably, the first conveying assembly 311 and the second conveying assembly can be structures such as conveyor belts or conveyor rollers.

[0067] It can be understood that the flipping assembly 320 is rotatably connected to the flipping platform 310, and the flipping assembly 320 can be swingably set and formed with a first station and a second station. When in the first station, the surface of the flipping assembly 320 is lower than or equal to the conveying surface of the first conveying assembly 311. When in the second station, the flipping assembly 320 swings and is set at a preset angle to the conveying surface of the first conveying assembly 311, thereby lifting the bed core so that the bed core is inclined against the telescopic assembly 330 at a preset angle; in some embodiments, the flipping assembly 320 includes a cylinder and a swing arm, and the swing arm is normally hidden in the flipping platform 310. After the first conveying assembly 311 conveys the bed core to a suitable position, the cylinder drives the swing arm to swing, and the swing arm directly lifts one end of the bed core and swings synchronously. After swinging more than 90°, the bed core falls on the telescopic assembly 330.

[0068] It is understood that the telescopic assembly 330 is located at the tail end of the flip platform 310. The telescopic assembly 330 includes a roller and a telescopic member. The telescopic member is used to drive the roller to rise and fall. The axis of the roller is set perpendicular to the conveying direction of the conveying assembly 311, and the axis of the roller is parallel to the conveying surface of the first conveying assembly 311. The telescopic member cooperates with the first conveying assembly 311 to convey the bed core through telescoping, so that the bed core slides from the roller to the flip platform. In some embodiments, the roller has a certain length and extends along the width direction of the bed core to stably support the bed core. The telescopic member is a telescopic mechanism with at least one level, preferably a two-stage telescopic mechanism, so that the roller is raised to a sufficient height to support the bed core. It should be noted that the bed core is tilted against the roller, and under the action of the first conveying assembly 311, the bed core is flipped up and down. The flipped bed core is centered by the centering assembly 340 and is once again sent to the positioning mechanism 200 to complete the frame fixation on the other side.

[0069] The centering assembly 340 includes at least two push plates and a pushing assembly. The push plates are respectively located on both sides of the conveying surface of the first conveying assembly. The pushing assembly is used to push the push plates relatively close to each other, so as to align the bed core. In some embodiments, the flip platform 310 includes a movable baffle 341 that can be raised and lowered. The movable baffle 341 is arranged between the flip platform 310 and the load-bearing platform 210. The movable baffle 341 is arranged perpendicular to the conveying direction of the first conveying assembly 311. The movable baffle 341 is suitable for extending when the flip platform 310 outputs the bed core to the load-bearing platform 210. The movable baffle 341 cooperates with the first conveying assembly 311 to determine the starting position of the bed core during movement. Specifically, the bed core is hidden when it is transferred from the carrying platform 210 to the flip platform 310, and is extended when it is transferred from the flip platform 310 to the carrying platform 210. The movable baffle 341 cooperates with the first conveying assembly 311 to correct the orientation of the bed core, so that the bed core is further straightened after colliding with the movable baffle 341, and cooperates with the guide rails on both sides to better realize the posture adjustment of the bed core.

[0070] In some embodiments of the present invention, specific reference is made to Figure 2 The loading mechanism 100 includes a third conveyor belt 110, on which a plurality of stoppers 120 are arranged at intervals. One side of each frame is hung on the third conveyor belt 110 and separated by the stoppers 120. The intervals between adjacent stoppers 120 define a delivery position for conveying the frame. It is understood that each delivery position is sequentially formed on the third conveyor belt 110 along the conveying direction. By placing a frame in advance on each delivery position, automatic frame positioning can be achieved. Considering that the frame has a certain size, multiple third conveyor belts 110 can be provided, and each third conveyor belt 110 is arranged at intervals from each other. Each delivery position along the spacing direction is used to convey the same frame, thereby achieving stable and continuous loading.

[0071] In some embodiments of the present invention, specific reference is made to Figures 4 to 7 The limiting component 230 includes at least one flap 231, a first drive member 232 and a second drive member 233. The flap 231 is bent and formed with an opening. When the frame is received at the material receiving station, the opening of the flap 231 is upward, and when it is in the positioning station, the opening of the flap 231 is downward, wherein the flap 231 is provided with a magnetic adsorption part and is suitable for limiting one side of the frame at the positioning station. The first drive member 232 is used to drive the flap 231 to flip, and the second drive member 233 is used to drive the flap 232 to move horizontally, so that the flap 231 is converted between the material receiving station and the positioning station, and when the flap is in the positioning station, the frame is fitted to the bed core. Preferably, a flap 231, a first drive member 232, and a second drive member 233 form a group, each group acting on each side of the frame respectively. The flap 231 is provided with a magnetic adsorption member and is suitable for receiving and limiting one side of the frame at the material receiving station. It is understood that after the flap 231 receives the material at the material receiving station, it is driven by the second drive member 233 to move to the positioning station, which is located directly above the side of the bed core. It is then driven by the first drive member 232 to flip over. When the supporting platform 210 is lifted, the bed core and the flap 231 move relative to each other and approach each other. Finally, the flap 231 will fit the sides of the bed core, thereby achieving the effect of each flap 231 fitting the sides of the bed core when it is in the positioning station. It is understood that each flap 231 acts on each side of each frame, and the actions of each flap 231 are synchronized to ensure that the frame does not deform. The flap 231 receives the frame and drives the frame to adjust to a suitable position to cooperate with the bed core. Before adjustment, it is necessary to ensure that the magnetic adsorption parts can reliably fix each frame to avoid mistakes.

[0072] Preferably, a magnetic attraction member is provided on the flap 231, so that the flap 231 can magnetically attract and position the frame relative to the flap 231, thereby allowing for synchronous movement. The magnetic attraction member can be a magnet or an electromagnet, etc., to ensure that the frame does not slip when the flap 231 is flipped and moved, and the frame can be slid and fine-tuned on the surface of the flap 231 to maintain a suitable position.

[0073] In some embodiments, the flap 231 includes a supporting portion and a fitting portion connected in sequence. The supporting portion is used to receive the frame. The supporting portion and the fitting portion are arranged at a preset angle. The supporting portion is used to receive the frame. After the flap 231 is flipped so that the fitting portion is downward, the supporting platform 210 and the limiting component 230 move relative to each other, so that the fitting portion fits the upper surface of the bed core for positioning. The supporting portion limits the frame at the connection between the supporting portion and the fitting portion and then fits the edge of the bed core. Specifically, when the supporting platform 210 is raised, the fitting portion is suitable for fitting the upper surface of the bed core for positioning. The supporting portion is suitable for driving the frame to move when moving, and limits the frame at the connection between the supporting portion and the fitting portion and then fits the bed core. It can be understood that before the flip plate 231 is flipped over, the bearing portion is used to bear and adsorb the frame, and the fitting portion is used to limit the frame to prevent the frame from slipping out. After the flip plate 231 is flipped over, the bearing portion continues to adsorb the frame and can allow the frame to slide and fine-tune. The fitting portion can be positioned on the upper surface of the bed core when the bearing platform 210 is lifted. At the same time, based on the characteristics of the magnetic adsorption part, during the movement of the flip plate 231, the frame can slide and fine-tune on the surface of the flip plate 231, and will eventually be stuck in the bearing portion and the fitting portion under the premise of always being limited to the flip plate 231, thereby accurately positioning.

[0074] In some embodiments of the present invention, specific reference is made to Figure 4 and Figure 5 The driving assembly includes a third driving member 221 and a fourth driving member 222. The third driving member 221 is used to drive the nail gun 223 to move along one side of the frame to adjust the position of the nail gun 223 facing the frame and the bed core. The fourth driving member 222 is used to drive the nail gun 223 to move in the direction of approaching or moving away from the frame to gradually position the frame on the bed core. After the supporting platform 210 and the first driving member 232 and the second driving member 233 cooperate with each other, the frame and the bed core are correctly positioned. The third driving member 221 is used to drive the nail gun 223 to move so that the nail gun 223 faces the edge of the frame and the bed core. For details, refer to Figure 6 and Figure 7The nail gun 223 and the flap 231 cooperate with each other to gradually position the frame on the bed core. It can be understood that the second driving member 233 and the third driving member 221 are both electric cylinders, the first driving member 232 is a reduction motor, and the fourth driving member 222 is a cylinder. When the second driving member 233 is extended, it pushes the flap 231 to gradually move to the top of the side of the bed core, so that the frame is correctly positioned. The third driving member 221 can adjust the position of the nail gun 223 on the same side so that the nail gun 223 is facing the edge of the frame and the bed core spring. It should be noted that the supporting platform 210 is configured as a lifting platform, which makes it more convenient to position the frame and the bed core, and the bed core can avoid the limiting component 230 and the fixing component 220 by lifting the supporting platform 210 when transporting to different places. Specifically, the nail gun 223 is put into position by the third driving member 221, the flap 231 is moved and positioned by the second driving member 233, and finally the frame is positioned at a suitable position on the bed core in the height direction by lifting the lifting platform, thereby ensuring the accuracy of the positioning positions of the bed core, the frame and the nail gun 223.

[0075] In some embodiments, the flap 231 is configured as an L-shaped plate. After the L-shaped plate receives the frame at the material receiving station, it flips inward 90°. At this time, the frame is located below the L-shaped plate and is attracted by the magnet provided on the L-shaped plate. The supporting platform 210 rises so that the upper surface of the bed core contacts the lower surface of the L-shaped plate. Each second driving member 233 drives the flap 231 to move toward the middle at the same time, so that the L-shaped plate is located above each side of the bed core. After the supporting platform 210 is lifted, the nail gun 223 is adjusted to the position of the frame and the edge of the spring through the third driving member 221. The cylinder connected to the nail gun 223 extends, so that the nail gun 223 clamps the frame and the spring, and starts nailing at the same time to fix the frame to the upper surface of the pocket spring bed core.

[0076] Reference Figures 1 to 8 The bed core frame positioning method of the second embodiment of the present invention may be a method for positioning the bed core frame by applying the bed core frame positioning device of the first embodiment of the present invention;

[0077] The bed core frame positioning method includes the following steps:

[0078] Place the bed core on the carrying platform 210;

[0079] The loading mechanism 100 conveys the first frame to load the material;

[0080] The limiting component 230 receives the first frame delivered by the loading mechanism 110 at the receiving station and moves to the positioning station so that the first frame is placed directly above each side of the bed core. The limiting component 230 flips inward so that the first frame is relatively located below the limiting component 230. The carrying platform 210 is raised or the limiting component 230 is lowered so that the frame is placed on the first surface of the bed core.

[0081] After the nail gun 223 is aligned with the first frame and the edge of the bed core, the first frame and the first surface of the bed core are fixed together.

[0082] It is understandable that the bed core frame positioning method further includes the following steps:

[0083] The carrying platform 210 transports the mattress core to the turning mechanism 300 , which turns the mattress core over and then transports it back to the carrying platform 210 .

[0084] The loading mechanism 100 transports the second frame to realize loading, and the positioning mechanism 200 performs corresponding actions again to fix the second frame and the second surface of the bed core together.

[0085] In some embodiments, referring to Figures 1 to 8 , the bed core frame positioning method includes the following steps:

[0086] The carrying platform 210 receives the input mattress core. When the upper and lower surfaces of the mattress core are fixed with frames, the platform 210 enters a ready state to receive the next mattress core input.

[0087] The feeding mechanism 100 conveys the first frame to realize feeding. When a frame is fixed on one surface of the bed core, the feeding mechanism 100 enters a ready state to prepare to input the second frame.

[0088] The grabbing assembly 410 receives the first frame delivered by the feeding mechanism 100, and the transfer assembly 420 drives the grabbing assembly 410 to move along a preset moving path, placing each side of the first frame on each flap 231, and fixing the first frame relatively to each other via magnetic adsorption members. After the transfer assembly 420 drives the grabbing assembly 410 to dock with each flap 231, the transfer assembly 420 drives the grabbing assembly 410 to reset, waiting for the next input of the second frame.

[0089] The second driving member 233 drives each flap 231 to move until each flap 231 is located directly above each side surface of the bed core. Then, each flap 231 flips inward so that the first frame is relatively located below the flap 231. Each flap 231 maintains its position and the supporting platform 210 is lifted, so that the bed core and the first frame are successfully positioned. Then, the first frame and the bed core are fixed together by the fixing member 220. The third driving member 221 drives the nail gun 223 so that the nail gun 223 is directly aligned with the first frame and the edge of the bed core. Then, the nail gun 223 fixes the first frame to the first surface of the bed core.

[0090] After the first frame is fixed to the bed core, the fixing member 220 is reset, and then the flaps 231 move away from each other and flip outward to achieve reset;

[0091] The second conveying assembly provided on the carrying platform 210 is used to convey the bed core. The carrying platform 210 transfers the bed core to the turning platform 310. The turning assembly 320 lifts the bed core to achieve turning, so that the bed core leans against the telescopic assembly 330 at a preset angle. The telescopic assembly 330 is in an extended state. When the bed core leans against the telescopic assembly 330, the turning assembly 320 returns to its original position.

[0092] The telescopic assembly 330 telescopes and cooperates with the first conveying assembly 311 to convey the bed core, causing the bed core to slide from the telescopic assembly 330 to the turnover platform 310 for flipping over. The telescopic assembly 330 shortens, causing the bed core to move obliquely downward in the same direction as the conveying direction of the first conveying assembly 311, so that the bed core is transported along the first conveying assembly 311 until it is horizontally loaded on the carrying platform 210, and then the telescopic assembly 330 extends and resets.

[0093] The first conveying assembly 311 transports the mattress core back to the carrying platform 210. During the process, the mattress core is straightened by the movable baffle 341 and the centering assembly 340, and then returns to the carrying platform 210 in a preset posture.

[0094] The loading mechanism 100 conveys the second frame to realize loading, and the frame removal mechanism 400 conveys the second frame to the positioning mechanism 200;

[0095] Positioning mechanism 200 again performs the corresponding action to secure the second frame to the second surface of the mattress core. It is understood that, assuming that all mechanisms have been reset and are in a ready state, the first and second frames are positioned in the same manner. Therefore, the corresponding actions performed by positioning mechanism 200 can be referred to as those performed when positioning the first frame, and will not be further described here.

The spring mattress production line includes the bed core frame positioning device of the first embodiment of the present invention, which can effectively improve production efficiency and reduce labor costs on the basis of realizing the automation of frame making by the bed core frame positioning device.
