Description

Technical Field

[0001] This invention relates to the field of mattress packaging technology, and more particularly to a mattress packaging device. Background Technology

[0002] To facilitate the handling, storage, and transportation of mattresses, the industry generally uses a roll-packing process to package them. This involves first compressing the mattress with a compressor, then conveying it to a roll-packing machine via a roller table for rolling.

[0003] However, when using commercially available compressors to compress mattresses, the mattresses are manually lifted one by one onto the compressor for compression, resulting in low compression efficiency and potential safety hazards. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a mattress packing device that can improve mattress compression efficiency and enhance safety.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] Mattress packing equipment includes a base, a compression device, a stacking and conveying device, and a control device for controlling the operation of both the compression device and the stacking and conveying device;

[0007] The stacking and transfer device includes:

[0008] The support assembly includes a support plate, a support plate, and a first lifting drive mechanism. The support plate is swayably mounted on the support plate and is movably mounted on the base. The first lifting drive mechanism is mounted on the support plate and connected to the support plate to drive the support plate to lift and lower, thereby enabling the support plate to unload the mattress.

[0009] A transfer drive mechanism, connected to the support assembly, is used to drive the support assembly closer to or away from the compression device to transfer the mattress to the compression device; and

[0010] A stacking aid component is disposed on the base and has an auxiliary stacking state and a avoidance state. In the auxiliary stacking state, the stacking aid component can block multiple mattresses located on the support plate to make the multiple mattresses stacked neatly. In the avoidance state, the stacking aid component moves away from the support component so that the support component can move in a direction close to the compression device.

[0011] Further, the compression device includes:

[0012] A first support portion is provided on the base and is used to support the mattress;

[0013] A pressure plate is disposed above the first support portion;

[0014] A second lifting drive mechanism, connected to the pressure plate, is used to drive the pressure plate to move up and down relative to the first support portion, thereby enabling the pressure plate to compress the mattress located on the first support portion; and

[0015] A synchronization component is disposed between the base and the pressure plate to keep the pressure plate horizontal.

[0016] Furthermore, the compression device also includes:

[0017] A first guide assembly is used to guide the pressure plate.

[0018] Furthermore, the second lifting drive mechanism includes a hydraulic cylinder, the cylinder body of which is connected to the base body;

[0019] The first guide assembly includes a guide rod and a guide block with a guide hole. The guide rod is erected on the base and cooperates with the guide hole. The guide block is disposed on the telescopic rod of the hydraulic cylinder and connected to the pressure plate.

[0020] Furthermore, the synchronization component includes:

[0021] Synchronous linkage, rotatably mounted on the pressure plate;

[0022] Two gears, the two gears being positioned at opposite ends of the synchronizing link; and

[0023] Two racks are vertically and spaced apart on the base, and each rack meshes with each gear in a corresponding manner.

[0024] Furthermore, the first lifting drive mechanism includes a first cylinder, the cylinder body of the first cylinder is connected to the support plate, and the telescopic rod of the first cylinder is pivotally connected to the support plate.

[0025] Furthermore, the transfer drive mechanism includes:

[0026] The motor is mounted on the base.

[0027] Two drive shafts are rotatably mounted on the base. The two drive shafts are spaced apart, and one of the drive shafts is connected to the output end of the motor.

[0028] Sprockets, each of the drive shafts having a sprocket at both ends; and

[0029] A chain is movably wound between two adjacent sprockets of the two drive shafts and connected to the support plate.

[0030] Furthermore, the stacking auxiliary component includes:

[0031] A revolving door, rotatably mounted on the base;

[0032] A rotary drive mechanism, mounted on the base, is used to drive the rotating door to switch between the auxiliary stacking state and the avoidance state; and

[0033] A positioning mechanism, disposed on the base, is used to maintain the auxiliary stacking state of the revolving door.

[0034] Furthermore, the base is provided with a passageway through which the supporting assembly can pass, and the revolving door can cover at least a portion of the passageway when it is in an auxiliary stacking state.

[0035] Furthermore, the positioning mechanism includes:

[0036] A first blocking member is disposed on the base and is used to abut against a first side of the opposite sides of the revolving door;

[0037] The second blocking member is used to abut against the second side of the opposite sides of the revolving door; and

[0038] The third cylinder is mounted on the base and connected to the second blocking member, and is used to drive the second blocking member to abut or dismount from the rotating door.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] Because it integrates a compression device, a stacking and transfer device, and a control device, the stacking and transfer device and the compression device can be controlled automatically by the control device. This enables multiple mattresses to be neatly stacked on a support plate and then transferred to the compression device for compression. It can replace manual stacking, manual transportation of mattresses, manual unloading of mattresses, and automated compression of mattresses. The mattress delivery efficiency is high and the safety is higher. Attached Figure Description

Detailed Implementation

[0050] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0051] See Figure 1 This invention illustrates a preferred embodiment of a mattress packing device, including a base 10, a compression device 20, a stacking and transferring device 30, and a control device 40 for controlling the operation of both the compression device 20 and the stacking and transferring device 30.

[0052] The stacking and transfer device 30 includes:

[0053] The support assembly 31 includes a support plate 311, a support plate 312, and a first lifting drive mechanism 313. The support plate 311 is swayably mounted on the support plate 312, and the support plate 312 is movably mounted on the base 10. The first lifting drive mechanism 313 is mounted on the support plate 312 and connected to the support plate 311 to drive the support plate 311 to lift and lower, so that the support plate 311 can unload the mattress 50.

[0054] The transfer drive mechanism 32, connected to the support assembly 31, is used to drive the support assembly 31 closer to or further away from the compression device 20 to transfer the mattress 50 to the compression device 20; and

[0055] The stacking auxiliary component 33 is disposed on the base 10 and has an auxiliary stacking state and a avoidance state. When in the auxiliary stacking state, the stacking auxiliary component 33 can resist multiple mattresses 50 located on the support plate 311 so that the multiple mattresses 50 are stacked neatly. When in the avoidance state, the stacking auxiliary component 33 moves away from the support component 31 so that the support component 31 can move in a direction close to the compression device 20.

[0056] The mattress packing equipment of the present invention integrates a compression device 20, a stacking and transferring device 30, and a control device 40. Therefore, the control device 40 can control the automated operation of both the stacking and transferring device 30 and the compression device 20, thereby enabling multiple mattresses 50 to be neatly stacked on the support plate 311 and then transferred to the compression device 20 for compression. This can replace manual stacking, manual transport of mattresses 50, manual unloading of mattresses 50, and automated compression of mattresses 50. The mattress 50 transport efficiency is high, and the safety is also higher.

[0057] See Figures 2-3 In a preferred embodiment, the compression device 20 includes: a first support portion 11, disposed on the base 10 and used to support the mattress 50; a pressure plate 21, disposed above the first support portion 11; a second lifting drive mechanism 22, connected to the pressure plate 21, used to drive the pressure plate 21 to move up and down relative to the first support portion 11 so that the pressure plate 21 can compress the mattress 50 located on the first support portion 11; and a synchronization component 23, disposed between the base 10 and the pressure plate 21, used to keep the pressure plate 21 horizontal. The arrangement of the synchronization component 23 ensures that the pressure plate 21 remains horizontal during the lifting process, ensuring the operational stability of the pressure plate 21, so that it applies force evenly to one or more mattresses 50, thereby ensuring that the mattresses 50 can be reliably compressed and possessing versatility.

[0058] See also Figures 2-3 In a preferred embodiment, the compression device 20 further includes a first guide assembly 24 for guiding the pressure plate 21 to make the pressure plate 21 run more stably.

[0059] Specifically, there are at least two sets of first guide components 24, which are placed on opposite sides of the pressure plate 21 to further improve the operational stability of the pressure plate 21.

[0060] Specifically, the second lifting drive mechanism 22 includes a hydraulic cylinder connected to the hydraulic system 27, with the cylinder body connected to the base 10; the first guide assembly 24 includes a guide rod 241 and a guide block 242 with a guide hole 2421. The guide rod 241 is vertically mounted on the base 10 and engages with the guide hole 2421, while the guide block 242 is mounted on the telescopic rod of the hydraulic cylinder and connected to the pressure plate 21. This second lifting drive mechanism 22 and the first guide assembly 24 have a simple structure, are easy to assemble, and are highly reliable and low in cost.

[0061] Of course, in other embodiments, the second lifting drive mechanism 22 may also be a combination of a cylinder, an electric push rod, or a motor and a linear drive assembly, while the first guide assembly 24 may be a structure including a slider and a guide rail.

[0062] Specifically, there are two sets of second lifting drive mechanisms 22, which are placed on opposite sides of the pressure plate 21 to make the pressure plate 21 run more smoothly.

[0063] Specifically, the synchronization component 23 is located between the two sets of second lifting drive mechanisms 22 to improve the connection reliability between the pressure plate 21 and the base 10, thereby further improving the operational stability of the pressure plate 21.

[0064] In a preferred embodiment, the number of synchronization components 23 is two sets, and the two sets of synchronization components 23 are arranged at intervals to further improve the operational stability of the pressure plate 21.

[0065] Specifically, the synchronization assembly 23 includes: a synchronization link 231, rotatably mounted on the pressure plate 21; two gears 232, respectively positioned at both ends of the synchronization link 231; and two racks 233, vertically and spaced apart on the base 10, with each rack 233 meshing with a corresponding gear 232. This synchronization assembly 23 has a simple structure and high reliability, ensuring a tight connection between the pressure plate 21 and the base 10, thereby making the operation of the pressure plate 21 more stable.

[0066] Of course, in other embodiments, the synchronization component 23 may also include a slider and a guide rail. The slider is disposed on the pressure plate 21 and the guide rail is disposed on the base 10. The slider and the guide rail slide together, which can also achieve stable operation of the pressure plate 21.

[0067] In a preferred embodiment, the pressure plate 21 is provided with a second support portion 211 on each of the opposite sides for the hook 80 to hang, so that the upper support plate 60 can be suspended below the pressure plate 21. In order to facilitate the movement of the compressed mattress 50, before compressing the mattress 50, the upper support plate 60 is suspended at the bottom of the pressure plate 21, and the lower support plate 70 is placed on the top of the first support portion 11. In this way, after compressing the mattress 50, the upper support plate 60 and the lower support plate 70 can be located at the top and bottom of the mattress 50, respectively. By fixing the upper support plate 60 and the lower support plate 70 together, the mattress 50 can be fixed, thereby facilitating the overall movement of the compressed mattress 50.

[0068] In a preferred embodiment, the base 10 is also provided with an upper limit switch 25 and a lower limit switch 26 to limit the pressure plate 21 to its upper and lower limits.

[0069] See Figures 4-6 In order to enable the support plate 311 to swing up and down relative to the support plate 312, the support plate 311 is pivotally mounted on the support plate 312 via connecting shafts 314. There are multiple connecting shafts 314, which are spaced apart along the length of the support plate 311 to improve the connection stability between the support plate 311 and the support plate 312.

[0070] See Figures 4-5 In this embodiment, there are two sets of support components 31, which are arranged at intervals to achieve stable support and transfer of the mattress 50.

[0071] See Figure 4 In a preferred embodiment, a second guide component is provided between the base 10 and the support plate 312. The second guide component is used to move and guide the support plate 312 so that the supporting component 31 can run stably in a set direction.

[0072] Specifically, the second guide assembly includes a guide wheel 341 rotatably mounted on the support plate 312 and a first guide rail 342 mounted on the base 10. The guide wheel 341 and the first guide rail 342 cooperate. This second guide assembly has a simple structure, is easy to assemble, and has high structural stability.

[0073] See Figures 4-5 Specifically, the first lifting drive mechanism 313 includes a first cylinder, the cylinder body of the first cylinder is connected to the support plate 312, and the telescopic rod of the first cylinder is pivotally connected to the support plate 311. That is, the lifting of the support plate 311 can be achieved through the first cylinder. The structure is simple, practical and low in cost.

[0074] Of course, in other embodiments, the first lifting drive mechanism 313 may also be a hydraulic cylinder or an electric actuator, etc.

[0075] See Figure 5In a preferred embodiment, the transfer drive mechanism 32 includes: a motor 321 mounted on the base 10; two drive shafts 322 rotatably mounted on the base 10, spaced apart, with one drive shaft 322 connected to the output end of the motor 321; sprockets 323 at both ends of each drive shaft 322; and a chain 324 movably wound around two adjacent sprockets 323 of the two drive shafts 322 and connected to the support plate 312. That is, the motor 321 drives the drive shafts 322 to rotate, which in turn drives the sprockets 323 to rotate, thereby driving the chain 324 to rotate. The rotation of the chain 324 then moves the support plate 312, thus moving the support assembly 31. This transfer drive mechanism 32 has high transmission accuracy, low cost, and high structural reliability.

[0076] Of course, in other embodiments, the transfer drive mechanism 32 may include a combination of a motor and a rack and pinion mechanism, or a combination of a motor and a lead screw and nut pair.

[0077] See Figure 5 In a preferred embodiment, to facilitate the assembly of the support plate 312 and the chain 324, a first connector 36 is provided between the support plate 312 and the chain 324, and a third guide component 35 is provided between the first connector 36 and the base 10 to support and guide the first connector 36, so that the supporting component 31 can operate more stably.

[0078] Specifically, the third guide component 35 includes a slider 351 connected to the first connector 36 and a second guide rail 352 connected to the base 10 and cooperating with the slider 351. This third guide component 35 has high structural reliability, which helps to improve the operational stability of the support component 31.

[0079] See Figure 4 as well as Figure 7 In a preferred embodiment, the stacking auxiliary component 33 includes: a rotating door 331 rotatably mounted on the base 10; a rotation drive mechanism 332 mounted on the base 10 for driving the rotating door 331 to switch between an auxiliary stacking state and an obstacle avoidance state; and a locking mechanism 333 mounted on the base 10 for maintaining the rotating door 331 in the auxiliary stacking state. That is, the rotating door 331 is driven to rotate by the rotation drive mechanism 332, allowing it to block multiple mattresses 50 located on the support plate 311, ensuring that the multiple mattresses 50 can be stacked neatly. The locking mechanism 333 ensures that the rotating door 331 reliably maintains the state of blocking the mattresses 50. The structure is simple, practical, low-cost, and highly reliable.

[0080] See also Figure 4 as well as Figure 7The base 10 is provided with a passageway 12 through which the supporting component 31 can pass. When the rotating door 331 is in the auxiliary stacking state, it can cover at least part of the passageway 12. That is, the rotating door 331 is in the closed state in the auxiliary stacking state and in the open state in the avoidance state.

[0081] See also Figure 4 as well as Figure 7 There are two sets of each of the three components: rotating door 331, rotating drive mechanism 332, and locking mechanism 333. The two sets of rotating doors 331 are located on opposite sides of the passageway 12. Each rotating drive mechanism 332 is connected to each rotating door 331 in a corresponding manner. Each locking mechanism 333 is used to maintain each rotating door 331 in an auxiliary stacking state. That is, the stacking auxiliary component 33 is a double rotating door 331 structure. The structure is simple and can ensure that multiple mattresses 50 are stacked neatly.

[0082] For details, see Figure 7 The rotary drive mechanism 332 includes a second cylinder 3321. A second connector 3322 is pivotally connected to the telescopic rod of the second cylinder 3321. The second connector 3322 is connected to the revolving door 331. A fourth guide assembly is provided between the second connector 3322 and the base 10. This rotary drive mechanism 332 has a simple structure, low cost and high reliability. The fourth guide assembly can support and guide the second connector 3322 to ensure the stable operation of the revolving door 331.

[0083] For details, see Figure 4 as well as Figure 7 The positioning mechanism 333 includes: a first blocking member 3331, disposed on the base 10, for abutting against a first side of opposite sides of the rotating door 331; a second blocking member 3332, for abutting against a second side of opposite sides of the rotating door 331; and a third cylinder 3333, disposed on the base 10 and connected to the second blocking member 3332, for driving the second blocking member 3332 to abut or disengage from the rotating door 331. That is, the first blocking member 3331 and the second blocking member 3332 limit the rotation door 331, enabling the rotating door 331 to be reliably maintained in a stacking auxiliary state. The structure is simple, practical, low-cost, and highly reliable.

[0084] The working principle of the mattress packaging device of the present invention is as follows:

[0085] 1. The rotary drive mechanism 332 drives the revolving door 331 to close, and the locking mechanism 333 opens to position the revolving door 331, ensuring that the revolving door 331 reliably maintains the closed state;

[0086] 2. The first lifting drive mechanism 313 drives the support plate 311 to rise, placing the lower support plate 70 on top of the support plate 311 and aligning it with the revolving door 331.

[0087] 3. Start stacking mattresses 50. Using the rotating door 331 as a locking mechanism can ensure that multiple mattresses 50 are stacked neatly in vertical order.

[0088] 4. After stacking is completed, open the rotating door 331, and the transfer drive mechanism 32 drives the support assembly 31 forward to transport it directly into the compression device 20 before stopping;

[0089] 5. The first lifting drive mechanism 313 drives the support plate 311 to descend, and the transfer drive mechanism 32 drives the support assembly 31 to return backward to realize the unloading action of the mattress 50.

[0090] 6. The second lifting drive mechanism 22 drives the pressure plate 21 to descend, thereby compressing the mattress 50.

[0091] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
