Description

Technical Field

[0001] This application relates to the field of automated mattress production technology, and in particular to a spring-feeding device and a mattress assembly equipment. Background Technology

[0002] The main component of a spring mattress is the spring net. The manufacturing process typically involves first connecting multiple springs sequentially to form pocket spring strings, and then welding these strings side-by-side. To improve welding efficiency, some spring net assembly equipment can weld two layers of net simultaneously. Therefore, during loading, this type of equipment needs to simultaneously feed two spring strings to ensure the simultaneous welding of both layers.

[0003] However, during the feeding process, the two spring strings are prone to tangling, which can easily lead to feeding difficulties or stagnation, hindering the production efficiency of the bed net. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this application provides a spring sorting device that can separate and sort two spring strings being fed, thereby solving the problem of the two spring strings becoming entangled. The technical solution adopted is as follows.

[0005] The first aspect of this application provides a spring-collecting device, which is disposed upstream of a feeding assembly along the conveying direction of a spring string. The spring-collecting device includes a first driving mechanism and a plurality of first conveying members. The plurality of first conveying members are spaced apart along the rotation axis direction. The first driving mechanism is connected to the first conveying members and drives the first conveying members to rotate. Each first conveying member is used to drive a spring string to move synchronously into the feeding assembly.

[0006] In some embodiments of this application, the spring device further includes a second drive mechanism for driving the first drive mechanism and the first conveyor to move along a first direction.

[0007] In some embodiments of this application, the spring-feeding device includes a guide structure disposed upstream of the first conveying member along the conveying direction of the spring string, the guide structure being used to guide the spring string into the first conveying member.

[0008] In some embodiments of this application, the guiding structure includes a first guide plate, a second guide plate, and a guide cover. The first guide plate and the guide cover form a guiding channel for the passage of a spring string. A flared opening is provided on the side of the guiding channel away from the first conveying member. The second guide plate is disposed at the end of the first guide plate near the first conveying member. The second guide plate connects the guiding channel and the first conveying member and guides the spring string into the first conveying member.

[0009] In some embodiments of this application, the spring feeding device further includes a limiting cover disposed on the outer periphery of the first conveying member, and the inner wall of the limiting cover and the outer periphery of the first conveying member define a feeding channel for conveying the spring string.

[0010] In some embodiments of this application, the spring device is provided with two first driving mechanisms and two first conveying members, each of the first driving mechanisms being used to drive one of the first conveying members to rotate, and the first driving mechanism being disposed on one side of the first conveying member along the rotation axis of the first conveying member.

[0011] In some embodiments of this application, the spring-feeding device is provided with two first conveying members, and the rotation axes of the two first conveying members are arranged at an angle so that the two spring strings gradually approach each other along the conveying direction.

[0012] In some embodiments of this application, the first conveyor includes a conveyor belt, the surface of which is used for transporting a string of springs; or

[0013] The first conveying component includes a dial or lever, the outer periphery of which is used to actuate the transport spring string.

[0014] Secondly, this application provides a bed frame assembly device, including a feeding assembly and a spring-arranging device provided in the first aspect. The feeding assembly reciprocates along a first direction to supply spring strings. Along the conveying direction of the spring strings, the spring-arranging device is disposed upstream of the feeding assembly. The feeding assembly includes multiple feeding channels. The number of first conveying members is configured to be the same as the number of feeding channels. The first conveying members convey spring strings corresponding to the feeding channels and reciprocate synchronously with the feeding assembly along the first direction.

[0015] In some embodiments of this application, the feeding assembly includes a second conveyor, which is arranged in pairs at intervals in a first direction to form the feeding channel. The feeding assembly has two or more layers of the feeding channel, which are stacked along a third direction. Each layer of the feeding channel corresponds to a spring string output by the first conveyor. At least one of the second conveyors is an active member, which includes at least one of a dial wheel, a roller, and a conveyor belt. The second conveyor is used to convey multiple rows of spring strings in parallel along a third direction, and the first conveyor is used to convey multiple rows of spring strings in parallel along the first direction.

[0016] The embodiments of this application have at least the following beneficial effects: by using the spring-handling device provided upstream of the feeding assembly, multiple spring strings can be conveyed separately. In this way, multiple spring strings can be separated before entering the feeding assembly, thereby preventing the spring strings from tangling with each other. This further effectively prevents the problem of feeding process stagnation and machine stoppage caused by the tangling of spring strings, ensuring feeding efficiency and bed production efficiency.

[0030] Please see Figure 1 The spring-arranging device 1000 proposed in this application can be applied in a bed net assembly device 2000, which is used to weld or bond adjacent rows of spring strings to form a bed net. The bed net assembly device 2000 includes a feeding assembly 500, which can simultaneously transport multiple rows of springs to the welding station within the bed net assembly device 2000 for welding. Before the spring strings are transported to the feeding assembly 500, this application provides the spring-arranging device 1000 to separate the multiple spring strings individually, preventing them from tangling.

[0031] Other components and operations of the bed net assembly device 2000 have been described in the relevant art to those skilled in the art, and will not be described in detail here. The structure of the spring-feeding device 1000 will be described below.

[0032] The first aspect of this application provides a spring-operated device 1000, please refer to [link / reference]. Figure 1 and Figure 2 The spring-arranging device 1000 is positioned upstream of the feeding assembly 500 along the conveying direction of the spring strings. The spring-arranging device 1000 includes a first drive mechanism 100 and multiple first conveying members 200. The multiple first conveying members 200 are spaced apart along the rotation axis. The first drive mechanism 100 is connected to the first conveying members 200 and drives them to rotate. Each first conveying member 200 is used to synchronously move one spring string into the feeding assembly 500. By utilizing the spring-arranging device 1000 positioned upstream of the feeding assembly 500, multiple spring strings can be conveyed separately. This allows the multiple spring strings to be separated before entering the feeding assembly 500, preventing them from tangling together. This further effectively prevents the feeding process from stalling or stopping due to tangling, ensuring feeding efficiency and bed production efficiency.

[0033] Optionally, the first drive mechanism 100 may be a motor. In some examples, the first conveyor 200 includes a conveyor belt, the surface of which is used to transport the spring string. For example, the motor drives the conveyor belt to move, utilizing the friction between the surface of the conveyor belt and the sides of the spring string to move the spring string. Or in other examples, the first conveyor 200 includes a wheel or lever, the outer periphery of which is used to transport the spring string. Figure 2 and Figure 4 As shown, the first conveying component 200 is a dial wheel, and the outer peripheral side of the dial wheel has a claw 210. The groove formed between two adjacent claws 210 is used to engage with the side of the spring string. The motor drives the dial wheel to rotate, thereby driving the spring string to move.

[0034] For example, the spring-arranging device 1000 can be correspondingly installed at the discharge end of the spring machine. That is, after the spring machine completes the spring winding, it loads the springs into a cloth bag and sews or welds them to form a spring string with multiple independent springs. The spring string enters the spring-arranging device 1000 after being output from the spring machine. The spring-arranging device 1000 separates the multiple spring strings, enabling them to enter the feeding assembly 500 of the bed net assembly equipment 2000 in an orderly manner.

[0035] In some embodiments, the spring-fed device 1000 includes a guide structure 300 disposed upstream of the first conveyor 200 along the conveying direction of the spring string, and the guide structure 300 is used to guide the spring string into the first conveyor 200. See also... Figure 2 The spring string can be arranged according to Figure 2 The springs are conveyed along the direction of the arrow and along the dotted line trajectory. The guide structure 300 serves to connect the spring string from the spring machine to the first conveyor 200, allowing the spring string to enter the first conveyor 200 more smoothly, reducing the occurrence of spring string jamming, and improving the smoothness of spring string conveying and connection.

[0036] In some embodiments, the guide structure 300 includes a first guide plate 310, which is disposed along a direction parallel to the axis of rotation of the first conveyor 200. The first guide plate 310 is used to guide the movement of the spring string along its length. The first guide plate 310 can support the side of the spring string, allowing the spring string to move along the extension direction of the first guide plate 310 and smoothly enter the first conveyor 200. The surface of the first guide plate 310 is disposed parallel to the axis of rotation of the first conveyor 200, which helps to straighten the spring string, prevent the spring string from twisting, and make the spring string roughly flat on the surface of the first guide plate 310 and easy to enter the first conveyor 200, thereby improving the smoothness of the spring string conveying and effectively preventing the problem of entanglement between multiple spring strings.

[0037] In some embodiments, the first guide plate 310 has a guide surface 311 for contacting the spring string, and a first guide portion 312 is provided at one end of the first guide plate 310 away from the first conveying member 200. The first guide portion 312 is curved along the side opposite to the guide surface 311. By providing the first guide portion 312 that is curved away from the guide surface 311, the first guide plate 310 can form a smooth edge, preventing the recessed position between two adjacent springs in the spring string from being stuck in the edge of the first guide plate 310, thereby improving the smoothness of the spring string conveying process.

[0038] In some embodiments, the guide structure 300 further includes two second guide plates 320 spaced apart along the rotation axis of the first conveyor 200. The space between the two guide plates is used for the passage of the spring string. The second guide plates 320 are disposed on the guide surface 311 of the first guide plate 310, and the second guide plates 320 are disposed at the end of the first guide plate 310 near the first conveyor 200. The second guide plates 320 serve two purposes: firstly, they limit the two ends of the spring string, preventing it from shifting, twisting, flipping, or falling off the guide surface 311; secondly, the paired second guide plates 320 clamp the two ends of the spring string, preventing spring bounce and other problems, thereby improving the reliability of the spring string conveying.

[0039] In some embodiments, the guide structure 300 further includes a guide cover 330 disposed on the guide surface 311 of the first guide plate 310. The guide cover 330 is disposed upstream of the second guide plate 320 along the conveying direction of the spring string. The guide cover 330 and the guide surface 311 enclose a guide channel 331 for the spring string to pass through. By providing the guide channel 331, the radial direction of the spring string can be limited, thereby ensuring that the spring string remains in contact with the guide surface 311 during transport, and ensuring that the spring string can enter the first conveying member 200 more smoothly for conveying.

[0040] In some embodiments, a second guide portion 332 is provided at the end of the guide cover 330 away from the second guide plate 320. The second guide portion 332 is flared outward in the direction away from the guide channel 331, so that the inner diameter of the guide channel 331 gradually decreases along the conveying direction of the spring string. The outward flared arrangement of the second guide portion 332 enables the entrance of the guide channel 331 to form a funnel-shaped structure. That is, the guide channel 331 has a funnel-shaped opening on the side away from the first conveying member 200, thereby guiding in multiple directions and adapting to the situation where the spring string enters the first conveying member 200 from different directions. This not only improves the adaptability of the spring handling device 1000, but also improves the stability and smoothness of the spring string conveying.

[0041] In some embodiments, the spring handling device 1000 further includes a limiting cover 400, which is disposed on the outer periphery of the first conveying member 200. The inner wall of the limiting cover 400 and the outer periphery of the first conveying member 200 define a feeding channel 410 for conveying the spring string. By enclosing the outer periphery of the first conveying member 200 with the limiting cover 400, the inner wall of the limiting cover 400 and the outer periphery of the first conveying member 200 can define the feeding channel 410, thereby clamping and conveying the sides of the spring string, allowing the spring string to pass through the feeding channel 410. The limiting cover 400 also isolates the feeding channel 410, preventing debris in the production line from being drawn into the feeding channel 410, thereby improving the reliability and safety of the operation of the first conveying member 200.

[0042] In some embodiments, the spring-feeding device 1000 includes two first drive mechanisms 100 and two first conveying members 200. Each first drive mechanism 100 is used to drive one first conveying member 200 to rotate. The first drive mechanism 100 is disposed on one side of the first conveying member 200 along the axis of rotation of the first conveying member 200, and the two first conveying members 200 are located between the two first drive mechanisms 100. By distributing the two first drive mechanisms 100 on the outer side of the first conveying member 200, the distance between the two first conveying members 200 can be reduced, making the arrangement of the two first conveying members 200 more compact and reducing the space occupied by the spring-feeding device 1000.

[0043] Optionally, the first drive mechanism 100 can be located outside the limit cover 400 to avoid interfering with the rotation of the first conveyor 200.

[0044] In some embodiments, please refer to Figure 3 The spring-arranging device 1000 has two first conveying members 200, whose rotation axes are set at an angle to allow the two spring strings to gradually approach each other along the conveying direction. Typically, the feeding assembly 500 has multiple feeding channels 510. Taking a double-layer bed net assembly 2000 as an example, the feeding assembly 500 has two feeding channels 510. These two feeding channels 510 are usually arranged side-by-side or stacked vertically along the spring axis in the feeding assembly 500, thus allowing for a compact arrangement. Therefore, by setting the rotation axes of the two first conveying members 200 at an angle, the two spring strings can gradually approach each other after passing through the spring-arranging device 1000, thereby adapting to the spacing of the two feeding channels 510 in the feeding assembly 500 and improving the smoothness of the spring strings during conveying. For example, the included angle θ of the rotating shafts of the two first conveying components 200 satisfies 90° < θ < 180°, that is, the included angle can be 100°, 120°, 150°, 175°, etc.

[0045] Secondly, please refer to the following:Figure 1 This application also provides a bed frame assembly device 2000, including a feeding assembly 500 and a spring-arranging device 1000 provided in the first aspect. Along the conveying direction of the spring strings, the spring-arranging device 1000 is disposed upstream of the feeding assembly 500. The feeding assembly 500 includes multiple feeding channels 510. First conveying members 200 are configured in the same number as the feeding channels 510, and the first conveying members 200 convey the spring strings corresponding to the feeding channels 510. Figure 1 For example, the feeding channel 510 is set to two, and correspondingly, the first conveying component 200 of the spring handling device 1000 is also set to two. In this way, the spring handling device 1000 can independently convey the two spring strings, so that the two spring strings enter the two feeding channels 510 respectively, avoiding the problem of the spring strings getting tangled during the feeding process.

[0046] In some embodiments, the feeding assembly 500 is used to feed along a first direction (e.g., Figure 1 The spring handling device 1000, which reciprocates in the x-direction (as shown) to supply the spring strings to the welding station, also includes a second drive mechanism. This second drive mechanism drives the first conveyor 200 and the first drive mechanism 100 to reciprocate synchronously along the first direction, following the feeding assembly 500. By utilizing the movement of the feeding assembly 500 in the first direction, the spring strings can be placed at the welding station, arranging them along the first direction. Therefore, by using the second drive mechanism 200 and the first drive mechanism 100 to reciprocate synchronously along the first direction with the feeding assembly 500, it is ensured that the spring strings can be continuously fed into the feeding channel 510, and the problem of multiple spring strings becoming entangled during the feeding process is solved, improving the reliability of the spring string feeding process.

[0047] Optionally, the second drive mechanism can be a linear motor, cylinder, or rotary motor driving the screw to rotate, etc., and the second drive mechanism can drive the spring-holding device 1000 to move in the first direction. Optionally, the feeding assembly 500 and the spring-holding device 1000 can both be driven synchronously by the second drive mechanism, or a third drive structure (not shown) can be provided for the feeding assembly 500, and the third drive structure and the second drive mechanism can be configured to have synchronous drive actions.

[0048] In some embodiments, please refer to Figure 5 and Figure 6 The feeding assembly 500 includes a second conveyor 511, which are arranged in pairs at intervals in a first direction to form a feeding channel 510. The feeding assembly 500 has two or more layers of feeding channels 510, and the multiple layers of feeding channels 510 are arranged along a third direction (e.g., ...). Figure 1 The stacked arrangement (shown in the z-direction) means that each layer of the feeding channel 510 corresponds to a spring string with the output of the first conveyor 200. For example... Figure 5 andFigure 6 The feeding assembly 500 shown has two layers of feeding channels 510. A second conveyor 511 is used to convey multiple rows of spring strings in parallel along a third direction, and a first conveyor 200 is used to convey multiple rows of spring strings in parallel along a first direction. This allows the spring strings to be transported in a flat (i.e., "horizontal") manner in the spring-arranging device 1000, thus improving the stability of the springs as they pass through the device and reducing the space occupied by the device in the third direction. The rotating shaft of the second conveyor 511 is perpendicular to the first plane, allowing the spring strings to be conveyed in a standing position by the feeding assembly 500, thus meeting the placement requirements of the spring strings in the bed net assembly 2000. Since the spring strings are conveyed in different postures in the spring-arranging device 1000 and the feeding assembly 500, a certain distance needs to be maintained between them to ensure that the spring strings can be rotated from a flat posture to a standing posture.

[0049] In some embodiments, at least one second conveyor 511 is an active member, which includes at least one of a dial wheel, a roller, and a conveyor belt. The structure and function of the second conveyor 511 can be found in the description of the first conveyor 200, and will not be repeated here.

[0050] In some embodiments, the bed frame assembly 2000 includes a frame 600, a feeding assembly 500 movably disposed in the frame 600, a guide rail 610 disposed along a first direction on the frame 600, a spring-feeding device 1000 movably disposed on the guide rail 610, the rotating shafts of a plurality of first conveying members 200 being coplanarly disposed, and the rotating shafts of the plurality of first conveying members 200 defining a first plane, the first plane being parallel to the guide rail 610, the rotating shaft of a second conveying member 511 being perpendicular to the first plane, and the guide rail 610 being disposed along a second direction (e.g., ...). Figure 1 The guide rail 610 is spaced apart from the feeding assembly 500 in the first direction (y-direction shown) and the third direction. Utilizing the guiding effect of the guide rail 610, the spring-holding device 1000 can slide in the first direction, thereby improving the stability and reliability of the spring-holding device 1000's movement. By setting the first plane parallel to the guide rail 610, and thus the guide rail 610 being spaced apart from the feeding assembly 500 in the second and third directions, sufficient space is provided to accommodate the spring string located between the feeding assembly 500 and the spring-holding device 1000, allowing the spring string to switch postures within this space.

[0051] In some embodiments, the frame 600 further includes a bracket 620 extending in a second direction, and a guide rail 610 is mounted on the bracket 620 such that there is a gap between the guide rail 610 and the frame 600. The bracket 620 is spaced above the feeding assembly 500 in a third direction. By extending the bracket 620 in the second direction, a distance in the second direction can be formed between the mounting position of the spring-feeding device 1000 and the feeding assembly 500. Figure 1 For example, the second direction can be longitudinal. By setting the bracket 620 above the feeding assembly 500, a distance is formed in a third direction between the installation position of the spring-arranging device 1000 and the feeding assembly 500, which can be vertical. This arrangement of the bracket 620 serves two purposes: firstly, it secures the guide rail 610; secondly, it allows for a reasonable setting of the gap between the guide rail 610 and the feeding assembly 500, ensuring that the spring string has sufficient space to be conveyed from the spring-arranging device 1000 to the feeding assembly 500.

[0052] For example, the bracket 620 can be a support rod, and two support rods are provided. The two support rods are set on the top of the frame 600, and at least a portion of the support rods extends out of the frame 600 along a second direction. The two ends of the guide rail 610 are respectively installed on the two support rods. In this way, the guide rail 610 and the spring device 1000 can be installed, and the structure of the bed net combination device 2000 can be made more compact.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
