DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0029] Example 1, as Figures 1-8 As shown, an automatic storage and retrieval device for rolled carpets includes a shelf 1 and a bracket 2. The shelf 1 is installed in a three-dimensional warehouse, and the bracket 2 is installed on a stacker crane. The interior of the shelf 1 is provided with multiple groups of bottom supporting members 3 from top to bottom. The bottom supporting members 3 are trapezoidal in design, and the length of the side closest to the exit of the shelf 1 is shortened. The interior of the bottom supporting members 3 is provided with multiple groups of inner winding ropes 31.

[0030] A roller 4 is rotatably installed on the outside of the shelf 1. The roller 4 is conical in design, and the radius is small at the end close to the exit of the shelf 1. The bottom support 3 is fixedly installed on the side of the roller 4 away from the shelf 1. An inner shaft 5 is rotatably installed inside the roller 4. Multiple sets of reels 6 are fixedly installed on the outside of the inner shaft 5. The inner rope 31 is fixedly installed on the reel 6. The radius of the multiple sets of reels 6 decreases successively and has the same gradient direction as the roller 4.

[0031] During storage, the bottom support member 3 is in a relaxed state. Since the bottom support member 3 adopts a trapezoidal design and the length of one side close to the exit of the shelf 1 is short, the falling distance of this side is shorter when it is relaxed, so this side is higher than the other side, and the bottom support member 3 is in an overall downward slanted state. Then the bracket 2 is moved to a position above the bottom support member 3, and then the bracket 2 is controlled to swing so that the end close to the bottom support member 3 tilts downward. The rolled carpet on the bracket 2 automatically slides into the bottom support member 3 under the action of gravity, thereby completing the automatic storage of the rolled carpet, and the rolled carpets are stacked in the shelf 1, and will not be squeezed against each other under the supporting action of the bottom support member 3. At the same time, the rolled carpets are stacked obliquely, and the storage stability is high.

[0032] When the carpet is taken out, the winding roller 4 above the taken-in carpet is controlled to rotate, and the winding roller 4 rewinds the bottom support member 3. Since the winding roller 4 is conical in design and has a smaller radius at the end near the outlet of the shelf 1, the winding distance of the end of the winding roller 4 near the outlet of the shelf 1 is short. When the bottom support member 3 is straightened, the heights of the two ends of the bottom support member 3 are consistent, and the carpet above is lifted to a horizontal level, giving the carpet enough space to be taken out. At the same time, the inner shaft rod 5 corresponding to the taken-in carpet is controlled to rotate, and the inner shaft rod 5 drives the multiple sets of winding wheels 6 to rotate simultaneously. It should be noted that the radius of the group winding wheels 6 decreases in sequence and has the same gradient direction as the winding roller 4, but the gradient radius difference of the winding wheels 6 is greater than that of the winding roller 4, which makes the inner winding rope 31 at the innermost part of the shelf 1 straighten first, and the rest are still in a relaxed state. The inner winding rope 31 makes one end of the rolled carpet located inside the shelf 1 higher than the other end. It should be noted that the winding roller 4 does not rewind the bottom support member 3 in this position, and the height difference control is achieved by the tension of the multiple sets of inner winding ropes 31. Figure 1After the roll carpet is stored, the length of the roll carpet exceeds the length of the shelf 1, so when the roll carpet is obliquely slid downward, the lower end of the roll carpet will not be located between the two groups of inner winding ropes 31, and the inner winding ropes 31 will not block the stable downward sliding, at this time, the bracket 2 is moved to the lower side of the bottom supporting piece 3 by the stereoscopic warehouse stacking machine, and the end close to the bottom supporting piece 3 is inclined upward, so that the roll carpet can be automatically slid downward into the bracket 2, and the roll carpet at any position can be taken out according to the needs.

[0033] It should be noted that the bracket 2 is in an inclined state when taking and placing, and does not need to be inserted into the shelf 1, so the structure is simple, and the taking and placing space is small.

[0034] In the above embodiment, the outer side of the shelf 1 is provided with a mounting plate 11, the winding roller 4 is rotatably mounted between the mounting plates 11, and the outer side of the shelf 1 is provided with a through port 12, and the bottom supporting piece 3 passes through the through port 12.

[0035] Further, the outer side of the through port 12 is rotatably provided with a guide roller 13, and the setting of the guide roller 13 makes the winding of the bottom supporting piece 3 more stable.

[0036] In the above embodiment, the bracket 2 is designed in a half-ring shape, a plurality of discharging rollers 21 are rotatably mounted on the inner bottom of the bracket 2, and a baffle is arranged at the bottom end of the bracket 2, so that the bracket 2 can better adapt to the roll carpet, and the baffle can stably catch the roll carpet sliding downward.

[0037] In the above embodiment, the bottom of the bracket 2 is hingedly connected with a mounting base 22, the top of the mounting base 22 is hingedly connected with a telescopic drive 23, and the telescopic end of the telescopic drive 23 is hingedly connected to the bottom of the bracket 2.

[0038] The embodiment is more suitable for a stereoscopic warehouse stacking machine with only lifting capability, so an additional telescopic drive 23 is needed to control the inclination of the bracket 2, and the telescopic drive 23 can be a hydraulic cylinder, an electric telescopic rod or an air cylinder, which is selected according to the actual environment. If the stereoscopic warehouse stacking machine is a forklift, the bracket 2 can be directly mounted on the fork rod of the forklift, and the inclination angle of the fork rod can be adjusted by the forklift itself.

[0039] In the above embodiment, the bottom supporting piece 3 is composed of an upper polypropylene film and a lower woven layer, so that the roll carpet can be stably supported, the friction between the roll carpet and the bottom supporting piece 3 can be reduced, the taking and placing are more stable, and the moisture-proof effect is better.

[0040] Further, the inner part of the inner rope 31 is provided with an elastic rope guide pipe, and the inner rope 31 is arranged in the elastic rope guide pipe. Through the arrangement of the elastic rope guide pipe, when the bottom support 3 is relaxed, the stable arc structure can be maintained, the rolled carpet is stored more stably, and the inner rope 31 can be more stably wound relative to the bottom support 3.

[0041] In the above embodiment, the inner shaft rod 5 is provided with a transmission head 56, the outer side of the transmission head 56 is rotatably connected with a worm wheel 51, the worm wheel 51 is meshed with a worm, one side of the worm wheel 51 close to the winding roller 4 is provided with a drive sleeve 55, the inner wall of the drive sleeve 55 and the outer side of the transmission head 56 are both provided with a transmission groove, and the middle of the drive sleeve 55 is provided with a cavity.

[0042] Further, the top of the shelf 1 is fixedly connected with a driving motor 7, the output end of the driving motor 7 is fixedly connected with a driving shaft 8, the driving shaft 8 is composed of a plurality of worms, the outer side of the inner shaft rod 5 is provided with a transmission head 56, the outer side of the transmission head 56 is rotatably connected with a worm wheel 51, the worm wheel 51 is meshed with a worm, one side of the worm wheel 51 close to the winding roller 4 is provided with a drive sleeve 55, the inner wall of the drive sleeve 55 and the outer side of the transmission head 56 are both provided with a transmission groove, and the middle of the drive sleeve 55 is provided with a cavity.

[0043] It should be noted that when the electromagnet 52 is not powered, the transmission sleeve 54 is located in the drive sleeve 55 and the transmission sleeve 41, and the worm wheel 51 can drive the winding roller 4 to rotate. When the electromagnet 52 is powered, there are two gears. When taking out, the electromagnet 52 on the corresponding inner shaft rod 5 of the taken carpet is powered to the second gear, the electromagnet 52 drives the transmission sleeve 54 to slide out of the transmission sleeve 41 through magnetic force, and the transmission sleeve 54 exceeds the cavity of the drive sleeve 55 and slides into the position of the transmission head 56. The transmission sleeve 54 drives the worm wheel 51 to rotate the inner shaft rod 5, and the electromagnet 52 below the taken carpet is powered to the first gear, and the transmission sleeve 54 slides to the cavity position of the drive sleeve 55, that is, the worm wheel 51 at the taken position can drive the inner shaft rod 5 to rotate, the worm wheel 51 above drives the winding roller 4 to rotate, and the worm wheel 51 below idles.

[0044] At this time, the driving motor 7 is controlled to rotate, and the driving motor 7 drives all the worm gears 51 to rotate simultaneously through the worm drive, and the worm gears 51 above the taken carpet drive the winding roller 4 to rotate through the inner shaft 5, the transmission sliding sleeve 54 and the transmission outer sleeve 41, and the winding roller 4 winds the bottom support 3, since the winding roller 4 is designed in a conical shape and has a small radius near the outlet end of the shelf 1, the winding roller 4 winds a short distance near the outlet end of the shelf 1, when the bottom support 3 is straightened, the bottom support 3 has the same height at both ends, the carpet above is lifted to the horizontal to provide enough space for the taken carpet, and the carpet below remains unchanged, meanwhile, the inner shaft 5 corresponding to the taken carpet rotates, and the inner shaft 5 drives a plurality of winding rollers 6 to rotate simultaneously, it should be noted that the radii of the winding rollers 6 decrease in turn and have the same gradient direction as the winding roller 4, but the difference of the radii of the winding rollers 6 is greater than that of the winding roller 4, which makes the inner winding rope 31 in the innermost part of the shelf 1 straighten first, and the rest are still in a relaxed state, and the inner winding rope 31 makes one end of the rolled carpet in the innermost part of the shelf 1 higher than the other end, it should be noted that the winding roller 4 does not wind the bottom support 3, and the height difference is controlled by the tightness of the plurality of inner winding ropes 31, and as shown in the attached Figure 1 figure, the length of the rolled carpet exceeds the length of the shelf 1 after storage, so when it slides downward obliquely, the lower end of the rolled carpet will not be located between the two inner winding ropes 31, and the inner winding rope 31 will not block the downward sliding, at this time, the tray 2 is moved to the lower side of the bottom support 3 by the three-dimensional warehouse stacking machine, and the end close to the bottom support 3 is inclined upward, so that the rolled carpet can automatically slide downward into the tray 2, and the automatic taking of the rolled carpet is completed, and any position of the rolled carpet can be taken according to the needs.

[0045] Therefore, through the setting of the embodiment, all controls can be realized by simply setting a group of driving motors 7, and through the one-way transmission structure design of the worm gear and the worm, the overall state remains stable when the driving motor 7 is powered off, and the structure is simple and compact.

[0046] The above description of disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
