Description

Technical Field

[0001] This invention relates to the field of home textile or furniture technology, and in particular to a multi-station conveyor platform. Background Technology

[0002] Currently, in mattress production, due to the large size and weight of mattresses, specialized conveying equipment is required for their movement between processing stations. Generally, such conveying equipment uses multiple parallel drive rollers as the power source. The mattress is placed above the drive rollers, and as the rollers rotate, they apply a horizontal force to the mattress, thus moving it. To reduce slippage between the drive rollers and the mattress, drive belts can be installed on the multiple drive rollers. These belts increase the contact area with the mattress, ensuring stable transport.

[0003] However, in practical applications, it has been found that since mattresses are often covered with soft and lightweight fabrics, when using conveyor equipment that uses drive rollers as the driving source, the fabric can easily get caught in the drive rollers or belts. This can not only damage the mattress products, but in severe cases, it can even damage the conveyor equipment, causing the entire production line to stop and severely impacting production efficiency.

[0026] Currently, in mattress production, due to the large size and weight of mattresses, specialized conveying equipment is required for their movement between processing stations. Generally, such conveying equipment uses multiple parallel drive rollers as the power source. The mattress is placed above the drive rollers, and as the rollers rotate, they apply a horizontal force to the mattress, thus moving it. To reduce slippage between the drive rollers and the mattress, drive belts can be installed on the multiple drive rollers. These belts increase the contact area with the mattress, ensuring stable transport.

[0027] However, in practical applications, it has been found that since mattresses are often covered with soft and lightweight fabrics, when using conveyor equipment that uses drive rollers as the driving source, the fabric can easily get caught in the drive rollers or belts. This can not only damage the mattress products, but in severe cases, it can even damage the conveyor equipment, causing the entire production line to stop and severely impacting production efficiency.

[0028] Therefore, how to achieve long-distance transportation of soft sheet materials while avoiding fabric from getting caught in the conveying equipment is a technical problem that needs to be solved in the design of conveying equipment for mattresses or home textiles.

[0029] In response, this application proposes a multi-station conveying platform that supports mattresses by interlocking trays and uses a drive component to move the trays between a lifting station component and an intermediate station component, thereby completing the conveying of the mattresses. At the same time, the trays prevent the fabric on the mattresses from getting caught in the conveying equipment.

[0030] Reference Figure 1 The multi-station conveying platform in this embodiment includes a tray 100, a lifting station assembly 200, and an intermediate station assembly 300. The tray 100 supports sheet-like soft materials, such as fabric and sponge, preventing materials from entering one conveying platform from another during transport, thus preventing fabric from the mattress from getting caught in the gaps between different conveying platforms. The lifting station assembly 200 drives the tray 100 to move up and down. The intermediate station assembly 300 is equipped with two sets of guide rails of different heights, allowing the lifting station assembly 200 to feed the tray 100 into different guide rails in the intermediate station assembly 300. The tray 100 can be conveyed in different directions along different guide rails, preventing interference between the two conveying directions.

[0031] Specifically, two adjacent pallets 100 are interlocked by snap-fit ​​mechanisms, so that the pallets 100 are connected end-to-end to form a pallet assembly that can move as a whole. (Refer to...) Figure 2 and Figure 3 The latches specifically include a first latch 111 and a second latch 112, which are respectively disposed on opposite sides of the tray 100. It is worth noting that the second latch 112 is provided with a slot 1121, allowing the first latch 111 to be positioned along a third direction (refer to...). Figure 1 (in the z direction) enter into or exit from the card slot 1121.

[0032] The second latch 112 has a specific structure including a first connecting arm 1122 and a second connecting arm 1123 extending outwards. The ends of both the first connecting arm 1122 and the second connecting arm 1123 bend towards the middle of the second latch 112, thus forming a slot 1121. When the first latch 111 enters the slot 1121, its side can contact the inner walls of the first connecting arm 1122 and the second connecting arm 1123 and transmit force, allowing the interconnected trays 100 to move as a whole under external force. The ends of the first connecting arm 1122 and the second connecting arm 1123 are not connected; the first latch 111 can pass through the gap between the first connecting arm 1122 and the second connecting arm 1123 in a third direction, thereby enabling the first latch 111 and the second latch 112 to detach from each other.

[0033] Reference Figure 4 and Figure 5 The lifting station assembly 200 includes a first fixed frame 210, a movable frame 220, and a lifting component 230. The movable frame 220 is provided with a first guide rail 221 capable of supporting the pallet 100, and the movable frame 220 can move in a third direction under the drive of the lifting component 230.

[0034] Reference Figure 10 The intermediate workstation assembly 300 includes a second fixed frame 310, which has upper and lower layers. The upper layer of the second fixed frame 310 is provided with a second guide rail 311, and the lower layer of the second fixed frame 310 is provided with a third guide rail 312. The lifting assembly 230 drives the movable frame 220 to move in a third direction, enabling the first guide rail 221 to engage with the second guide rail 311 or the third guide rail 312, thereby allowing the pallet 100 to move from the first guide rail 221 to the second guide rail 311 or the third guide rail 312. It is worth noting that there are two lifting workstation assemblies 200, which are respectively located at both ends of the intermediate workstation assembly 300.

[0035] Furthermore, this multi-station conveyor platform also includes a drive assembly that drives the pallet 100 along a first direction (refer to...). Figure 4 (x1 direction) or the second direction (refer to) Figure 4 The first direction (x2 direction) moves in the opposite direction to the second direction.

[0036] The working principle of this multi-station conveyor platform is as follows: After the pallet 100 is supported by the first guide rail 221 on the movable frame 220, the lifting component 230 is controlled to drive the movable frame 220 to select whether the first guide rail 221 is connected to the second guide rail 311 or the third guide rail 312. When the first guide rail 221 is connected to the second guide rail 311, the pallet 100 moves along the first direction under the drive of the drive component; when the first guide rail 221 is connected to the third guide rail 312, the pallet 100 moves along the second direction under the drive of the drive component. This ensures that the driving directions of the pallet 100 on the second guide rail 311 and the third guide rail 312 are different, thus ensuring that pallets 100 transported in opposite directions do not interfere with each other. When a specific pallet 100 needs to be reversed, for example, switching from transport along a first direction to transport along a second direction, the pallet 100 moves into the lifting station assembly 200. The lifting assembly 230 then drives the movable frame 220 to move, causing the first guide rail 221 to engage with the third guide rail 312, thus completing the reversal of the pallet 100. Simultaneously, during the reversal process, the latches on the pallet 100 first unlock from the pallet assembly on the second guide rail 311, and then reconnect to the pallet assembly on the third guide rail 312. The unlocking and locking of the latches are completed synchronously during the reversal process.

[0037] Furthermore, the lifting assembly 230 can employ a pneumatic telescopic rod, a hydraulic telescopic rod, a screw mechanism, or a rack and pinion mechanism to lift the movable frame 220. In this embodiment, refer to... Figure 5 and Figure 6 The lifting assembly 230 employs a motor paired with a rack and pinion mechanism to achieve the lifting function. Specifically, the lifting assembly 230 includes a lifting motor 231, a transmission rod 232, a gear 234, and a rack 235. The transmission rod 232 is connected to the rotating shaft of the gear 234 and the lifting motor 231, and the gear 234 meshes with the rack 235. The lifting motor 231 is connected to the movable frame 220, and the rack 235 is connected to the first fixed frame 210. When the lifting motor 231 starts, its torque is transmitted to each gear 234 through the transmission rod 232. The gears 234 rotate on the rack 235, thereby converting the circumferential force into a linear force, driving the movable frame 220 to move in a third direction.

[0038] Furthermore, there are multiple gears 234 and racks 235, which are arranged in a one-to-one correspondence. The multiple racks 235 apply supporting force to the movable frame 220, reducing the risk of the movable frame 220 collapsing due to uneven force.

[0039] Furthermore, to prevent the pallet 100 from moving along the first or second direction during the lifting and lowering of the movable frame 220, limit holes are provided on the pallet 100, as shown in the figure. Figure 7 The movable frame 220 is provided with a first limiting rod 222. After the tray 100 moves to the first guide rail 221 and comes to a stop, the first limiting rod 222 can extend into the limiting hole to restrict the movement of the tray 100. Specifically, the first limiting rod 222 can move under the drive of a pneumatic telescopic rod, a hydraulic telescopic rod, or a screw mechanism.

[0040] Furthermore, to prevent the pallet 100 from jumping relative to the movable frame 220 in a third direction, a limiting roller 140 is provided on the side of the pallet 100, and a first limiting member 223 is provided on one side of the first guide rail 221. A space is left between the first limiting member 223 and the first guide rail 221 to accommodate the limiting roller 140. When the pallet 100 moves onto the first guide rail 221 in a first or second direction, the limiting roller 140 can enter the space between the first limiting member 223 and the first guide rail 221. Therefore, when the pallet 100 jumps in a third direction, on the one hand, the roller 150 on the pallet 100 abuts against the first guide rail 221, and on the other hand, the limiting roller 140 abuts against the first limiting member 223, jointly restricting the displacement of the pallet 100 in the third direction.

[0041] Optionally, the drive assembly includes a first drive assembly 241 and a second drive assembly 242. The first drive assembly 241 drives the tray 100 to move along a first direction, and the second drive assembly 242 drives the tray 100 to move along a second direction.

[0042] The first drive assembly 241 is disposed in the lifting station assembly 200 or any intermediate station assembly 300. The first drive assembly 241 includes a first slide rail 2411, a first moving member 2412, and a first drive member 2413. The first drive member 2413 drives the first moving member 2412 to move along the first slide rail 2411. The first moving member 2412 is provided with a telescopic pin 2414, and the tray 100 has a drive hole 120. (Reference) Figure 8 The telescopic pin 2414 can extend into the drive hole 120, so that the side of the telescopic pin 2414 can contact the inner wall of the drive hole 120 to transmit force and drive the tray 100 to move. The driving method of the first driving member 2413 can be a pneumatic telescopic rod, a hydraulic telescopic rod, a screw mechanism, or a rack and pinion mechanism to transmit force. In this embodiment, the first driving member 2413 uses a motor combined with a rack and pinion mechanism to apply force to the first moving member 2412.

[0043] For the second drive component 242, refer to Figure 9 It includes a second moving member 2421 and a second driving member 2422. The second driving member 2422 drives the second moving member 2421 to move. The second moving member 2421 is specifically a chain, on which a driving block 2423 is provided. The driving block 2423 can contact the side of the pallet 100 to transmit force, thereby driving the pallet 100 to move in a second direction. Optionally, in order to reduce the frictional wear on the pallet 100 caused by the driving block 2423 contacting the pallet 100, an abutment block 130 is provided on the side of the pallet 100. The abutment block 130 directly contacts the driving block 2423 and transmits force.

[0044] Furthermore, the chain is positioned below the lifting station assembly 200 and the intermediate station assembly 300. In some embodiments, the chain runs through the multi-station conveyor platform; or in other embodiments, multiple sets of interconnected chains are provided between each lifting station assembly 200 and the intermediate station assembly 300.

[0045] Furthermore, multiple intermediate station components 300 are configured, with each second fixed frame 310 having a tray 100 on its upper layer. Each tray 100 is connected to each other front and back by snap-fit ​​mechanisms and is driven to move together by a drive assembly. Thus, by setting multiple intermediate station components 300, a conveying platform with a longer transmission distance is formed. The specific number of intermediate station components 300 can be increased or decreased according to actual needs.

[0046] Furthermore, the number of pallets 100 returning along the second direction in this multi-station conveyor platform is less than the number of pallets 100 moving along the first direction, ensuring that the number of pallets 100 moving along the first direction is sufficient.

[0047] Furthermore, for intermediate station component 300, refer to Figure 10 and Figure 11 The second fixed frame 310 is provided with a second limiting rod 313. After the tray 100 moves to the second guide rail 311 or the third guide rail 312 and comes to a stop, the second limiting rod 313 can extend into the limiting hole of the tray 100 to restrict the movement of the tray 100 along the first direction or the second direction. The second limiting rod 313 can move under the drive of a pneumatic telescopic rod, a hydraulic telescopic rod or a screw mechanism.

[0048] Furthermore, referring to Figure 11 A second limiting member 314 is provided on one side of the second guide rail 311, and a space is left between the second limiting member 314 and the second guide rail 311 to accommodate the limiting roller 140. When the pallet 100 moves onto the second guide rail 311 along the first direction or the second direction, the limiting roller 140 can enter the space between the second limiting member 314 and the second guide rail 311. Thus, when the pallet 100 jumps along a third direction, on the one hand, the roller 150 on the pallet 100 abuts against the second guide rail 311, and on the other hand, the limiting roller 140 abuts against the second limiting member 314, jointly restricting the displacement of the pallet 100 along the third direction.

[0049] Furthermore, referring to Figure 12 A third limiting member 315 is provided on one side of the third guide rail 312, and a space is left between the third limiting member 315 and the third guide rail 312 to accommodate the limiting roller 140. When the pallet 100 moves onto the third guide rail 312 along the first or second direction, the limiting roller 140 can enter the space between the third limiting member 315 and the third guide rail 312. Thus, when the pallet 100 jumps along the third direction, on the one hand, the roller 150 on the pallet 100 abuts against the third guide rail 312, and on the other hand, the limiting roller 140 abuts against the third limiting member 315, jointly restricting the displacement of the pallet 100 along the third direction.

[0050] Furthermore, to prevent the tray 100 from bending and deforming under the pressure of the mattress, both the first fixing frame 210 and the second fixing frame 310 are provided with auxiliary support wheels 400. These auxiliary support wheels 400 can roll in contact with the bottom of the tray 100, reducing friction between them and the tray 100 while applying support force to the tray 100.

[0051] The following describes the working method of this multi-station conveyor platform, including a first-direction transport mode and a second-direction transport mode. (Refer to...) Figure 13 The two lifting station components 200 are the first lifting station component 250 and the second lifting station component 260, respectively.

[0052] The primary mode of transportation includes: S110. In the first lifting station assembly 250 and the second lifting station assembly 260, the movable frame 220 moves so that the first guide rail 221 docks with the second guide rail 311. S120. The pallet 100 is moved from the first guide rail 221 of the first lifting station assembly 250 through the second guide rail 311 to the first guide rail 221 of the second lifting station assembly 260.

[0053] Specifically, the movable frame 220 moves along a third direction, driven by the lifting assembly 230. The first drive assembly 241 drives the pallet 100 to move along the first direction. By setting multiple lifting station assemblies 200 and intermediate station assemblies 300, the drive of the pallet 100 along the first direction can be continuously realized.

[0054] Second-direction transportation methods include: S210. In the first lifting station assembly 250 and the second lifting station assembly 260, the movable frame 220 moves so that the first guide rail 221 docks with the third guide rail 312. S220. The pallet 100 moves sequentially from the first guide rail 221 of the second lifting station 260 through the third guide rail 312 to the first guide rail 221 of the first lifting station assembly 250.

[0055] Specifically, the movable frame 220 moves along a third direction, driven by the lifting assembly 230. The second drive assembly 242 drives the pallet 100 to move along a second direction. By setting multiple lifting station assemblies 200 and intermediate station assemblies 300, the pallet 100 can be continuously driven along the second direction.

[0056] Furthermore, this working method also includes a reversing method, which includes the following steps: When the pallet moves along the first direction, the movable frame in the first lifting station assembly and the second lifting station assembly moves along the third direction, so that the first guide rail and the second guide rail are connected. When the pallet moves along the second direction, the movable frame in the first lifting station assembly and the second lifting station assembly moves along the third direction, so that the first guide rail is connected to the third guide rail; S310. When the pallet 100 moves along the first direction, the movable frame 220 in the first lifting station assembly 250 and the second lifting station assembly 260 moves along the third direction, so that the first guide rail 221 docks with the second guide rail 311. S320. When the pallet 100 moves along the second direction, the movable frame 220 in the first lifting station assembly 250 and the second lifting station assembly 260 moves along the third direction, so that the first guide rail 221 docks with the third guide rail 312.

[0057] Specifically, the movable frame 220 moves along a third direction, driven by the lifting assembly 230. The tray 100 is driven to move along a first direction by the first drive assembly 241, and the tray 100 is driven to move along a second direction by the second drive assembly 242.

[0058] 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 described in the embodiments of this application can be combined with each other.
