DETAILED DESCRIPTION

[0022] The essential characteristics of the utility model will be further explained below in combination with the drawing and specific embodiments.

[0023] For example, Figure 1 and 2The mattress unstacking device shown comprises a rack 1 with a receiving cavity, a lifting mechanism 2 arranged in the receiving cavity, an unstacking mechanism 3 arranged at the top of the receiving cavity, and a conveying mechanism 4 arranged adjacent to the rack 1. The receiving cavity is located below the unstacking mechanism 3 to form an unstacking station. The lifting mechanism 2 lifts the stack 5 formed by the stacked mattresses in the receiving cavity, so that the mattress at the top of the stack 5 is lifted to the unstacking station and is horizontally pushed by the unstacking mechanism 3 to the conveying mechanism 4 and is transported outward. The lifting mechanism 2 lifts the top of the stack 5 to the unstacking station, and the unstacking mechanism 3 drives the mattress in the unstacking station to be transported outward by the conveying mechanism 4. The lifting mechanism 2 continuously rises and keeps the top of the stack 5 in the unstacking station, so that the mattresses in the stack 5 are pushed and transported one by one from top to bottom, which facilitates quick unstacking, effectively improves the unstacking efficiency, and does not require manual operation, ensuring the safety of unstacking and improving the use experience.

[0024] In actual operation, a plurality of mattresses are vertically aligned and stacked to form a stack 5, which not only ensures that each region of the mattress is uniformly stressed to prevent the mattress from being bent and deformed, but also effectively saves floor space and improves the utilization efficiency of storage space. In order to facilitate the unstacking and transportation of each mattress in the stack 5, an unstacking device comprising a rack 1, a lifting mechanism 2, an unstacking mechanism 3, and a conveying mechanism 4 is provided to automatically unstack the stack 5, which not only effectively improves the unstacking efficiency but also ensures the safety of unstacking. In use:

[0025] First, adjust the supporting platform 6 to the lowest position, and move the stack 5 stacked in the channel 19 to the supporting platform 6;

[0026] Then, the two unstacking plates 13 are driven by the unstacking motor 15 to move to the pushing station and the reset station at both ends of the unstacking station, and the supporting platform 6 is lifted upward by the lifting motor 9, so that the mattress at the top of the stack 5 is lifted to the unstacking station;

[0027] Then, the unstacking motor 15 drives the unstacking plate 13 to move, the unstacking plate 13 at the pushing station pushes the mattress at the top of the stack 5 to move to the conveying mechanism 4, and the unstacking plate 13 at the reset station moves away from the conveying mechanism 4 and switches to the pushing station. In this process, the mattress at the top of the stack 5 is pushed to the conveying mechanism 4 and is immediately transported;

[0028] Finally, the supporting platform 6 is lifted by the lifting motor 9 and drives the mattress at the top of the stack 5 to move to the unstacking station, so that the mattresses in the stack 5 are pushed one by one to the conveying mechanism 4 by the circulating unstacking plate 13 from top to bottom and are transported.

[0029] After the first mattress in stack 5 is transferred from top to bottom, the support platform lifts the second mattress at the top of stack 5 in a step-by-step manner to ensure that it is accurately lifted to the destacking station. This process is repeated so that each mattress in stack 5 is lifted to the destacking station in sequence and the destacking and transfer are completed.

[0030] In actual operation, the lifting mechanism 2 includes a supporting platform 6 and a drive assembly (such as...) that drives the supporting platform 6. Figure 3 As shown, the supporting platform 6 moves up and down horizontally within the receiving cavity to adjust the height of the stack 5. The mattress at the top of the stack 5 is lifted to the destabilizing station and conveyed outward through the destabilizing mechanism 3. The driving assembly includes two symmetrically positioned transmission parts on the end edges of the supporting platform 6 and a first driving part that drives the transmission parts in conjunction. The first driving part drives the end edges of the supporting platform 6 to move up and down synchronously through the transmission parts, so that the supporting platform 6 maintains a horizontal posture. The first driving part provides driving force for adjusting the height of the supporting platform 6, so that the mattress at the top of the stack 5 can be lifted in time after being transferred, thereby ensuring that the mattresses in the stack 5 can be pushed and transferred one by one.

[0031] In actual operation, the first drive unit includes two drive shafts 7 arranged along the side edges of the support platform 6, an annular chain 8 spanning between the drive shafts 7, and a lifting motor 9 that drives the drive shafts 7. The transmission unit includes two drive chains 10 symmetrically arranged on both sides of the end edge of the support platform 6 and a counterweight 11 arranged between the drive chains 10. The end of the drive shaft 7 is provided with a gear for engaging with the corresponding drive chain 10. One end of the drive chain 10 is fixedly connected to the corresponding corner of the support platform 6, the middle section passes around the corresponding gear, and the other end is fixedly connected to the counterweight 11. There are two drive shafts 7, one at the front edge and the other at the rear edge of the frame 1. The two drive shafts 7 are connected by a ring chain 8. Both ends of each drive shaft 7 are connected to a corresponding drive chain 10 via gears, resulting in four drive chains 10 on the frame 1 that are connected to the four corners of the support platform 6. One end of each drive chain 10 is fixed to the corresponding corner of the support platform 6, and the other end, after passing over the corresponding gear, is fixed to the corresponding counterweight 11. Drive chains 10 located on the same side of the frame 1 share a single counterweight 11 (e.g., ...). Figure 4 (As shown). In use, the lifting motor 9 drives four transmission chains 10 to run synchronously through the transmission shaft 7, causing the four corners of the support platform 6 to rise and fall synchronously, so that the support platform 6 rises and falls in a horizontal posture and controls the height of the mattress on top of the stack 5. By setting counterweights 11 to offset the weight of the support platform 6 and the stack 5 on it, the operating load of the lifting motor 9 is effectively reduced, the service life is extended, and the sensitivity of lifting control is improved.

[0032] In actual operation, the annular chains 8 are two, and are arranged along the axial direction of the transmission shafts 7, and the transmission shafts 7 are provided with linkage teeth engaged with the annular chains 8. The annular chains 8 are sleeved between the two transmission shafts 7, so that any transmission shaft 7 can drive the other transmission shaft 7 to rotate synchronously when driven to rotate by the lifting motor 9, thereby ensuring the synchronous operation of the four transmission chains 10.

[0033] In actual operation, the unstacking mechanism 3 includes an unstacking chain 12 arranged at the top of the accommodating cavity and arranged front-to-back, a second driving part for driving the unstacking chain 12 to rotate, and an unstacking plate 13 (as shown in Figure 5 ) arranged on the unstacking chain 12. The second driving part drives the unstacking plate 13 to move through the unstacking chain 12, so that the mattress located at the top of the stack 5 moves to the conveying mechanism 4. The unstacking chain 12 is two and symmetrically arranged on both sides of the top of the rack 1. The second driving part includes an unstacking shaft 14 bridged between the corresponding end portions of the unstacking chain 12, and an unstacking motor 15 arranged on the unstacking shaft 14. The unstacking plate 13 is two and bridged on the unstacking chain 12, so that the unstacking plate 13 is driven by the unstacking motor 15 to circulate along a predetermined path and alternately push the mattress located at the top of the stack 5. The unstacking chain 12 is annular and includes a lower linear segment and an upper linear segment. The unstacking plate 13 is two and is located at the pushing station and the resetting station, respectively. The pushing station is located at the end portion of the lower linear segment away from the conveying mechanism 4, and the resetting station is located at the end portion of the upper linear segment close to the conveying mechanism 4. When any unstacking plate 13 moves to the conveying mechanism 4 along the lower linear segment and pushes the mattress to transfer, the other unstacking plate 13 moves to the pushing station from the resetting station along the upper linear segment to switch. The two unstacking plates 13 are alternately switched between the pushing station and the resetting station to continuously push and transfer the subsequent mattress.

[0034] In actual operation, the conveying mechanism 4 is arranged at the rear of the rack 1. The inlet of the conveying mechanism 4 is consistent in height with the unstacking station, and the conveying mechanism 4 receives the mattress pushed out by the unstacking mechanism 3 through the inlet. The front of the rack 1 is provided with a passage 19 (as shown in Figure 6 ) for the stack 5 to enter the accommodating cavity, so that the feeding of the stack 5 and the transfer of the mattress do not interfere with each other. The width of the passage 19 is greater than the width of the mattress, so that the stack 5 can smoothly pass through the passage 19 and be placed on the supporting platform 6.

[0035] In actual operation, the conveying mechanism 4 comprises a first belt 16 and a second belt 17 connected in sequence, the first belt 16 is arranged obliquely and forms an inlet corresponding to the unstacking station, and the second belt 17 is arranged horizontally and conveys the mattress to a preset area. The rear end of the first belt 16 is connected with the front end of the second belt 17 for transferring the mattress. The front end of the first belt 16 forms the inlet of the conveying mechanism 4 and is arranged at the same height with the unstacking station, so as to conveniently receive the mattress horizontally output by the unstacking station. The first belt 16 is arranged obliquely, which effectively reduces the height of the rear end of the first belt 16, not only plays a role in reducing the height of the mattress, but also facilitates the second belt 17 to receive, and also facilitates the laying through reducing the setting height of the second belt 17.

[0036] In actual operation, the rack 1 comprises four vertical columns 18 arranged in a matrix shape, and the vertical columns 18 surround to form the containing cavity, and the vertical projection of the supporting platform 6 and the stack 5 completely falls into the horizontal section of the containing cavity. The vertical columns 18 are arranged to form the containing cavity for the lifting of the receiving box of the stack 5, prevent the user or foreign matter from entering the containing cavity, and ensure the operation safety.
