Description

Technical Field

[0001] The invention relates to the technical field of carpet storage and retrieval, and in particular to an automatic storage and retrieval device for rolled carpets. Background Art

[0002] Carpets are floor coverings made of natural fibers such as cotton, linen, wool, silk, grass yarn, or chemical synthetic fibers, which are knitted, planted, or woven by hand or mechanical processes. Due to their own characteristics, roll carpets are usually stored in rolls, as this helps save space and protect the integrity of the carpet.

[0003] Traditional carpet storage and retrieval methods usually rely on manual operations, with low storage and retrieval efficiency and long time consumption. In a Chinese patent (publication number: CN109230156B), an automatic storage and retrieval device for rolled carpets is disclosed, including: a shelf and a bracket that are arranged in conjunction, the bracket includes: a bracket base, installed on a three-dimensional warehouse stacker; a plurality of rolled carpet support members, fixedly connected to the top of the bracket base, the shelf includes: a "door" type frame; a plurality of rolled carpet support inclined surfaces, inclined from the top two sides of the "door" type frame to the middle; a first opening groove, penetrating downward from the middle of the top of the "door" type frame, forming a channel for the bracket to enter and exit the shelf; a second opening groove, arranged between two adjacent rolled carpet support inclined surfaces on the same side, forming a lifting channel for the bracket in the shelf, and the second opening groove corresponds to the rolled carpet support member. Although this patent can realize the automatic storage and retrieval of rolled carpets in a stereoscopic warehouse, only one rolled carpet can be stored on one device and it cannot be stacked, resulting in low space utilization. At the same time, when storing and retrieving, the bracket needs to be extended into the shelf, which results in longer time and more space required for storage and retrieval, affecting the space utilization of the stereoscopic warehouse. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and provide an automatic storage and retrieval device for rolled carpets.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] An automatic storage and retrieval device for rolled carpets, comprising a shelf and a bracket, wherein the shelf is installed in a stereoscopic warehouse, and the bracket is installed on a stereoscopic warehouse stacker, wherein multiple groups of bottom brackets are arranged from top to bottom inside the shelf, and the bottom brackets are designed in a trapezoidal shape, and the length of the side close to the shelf outlet is short, and multiple groups of inner coil ropes are arranged inside the bottom brackets;

[0007] A roller is rotatably installed on the outer side of the shelf. The roller is conical in design and has a small radius at one end close to the shelf exit. The bottom support is fixedly installed on the roller at the side away from the shelf. An inner shaft is rotatably installed inside the roller. Multiple sets of reels are fixedly installed on the outer side of the inner shaft. The inner rope is fixedly installed on the reels. The radii of the multiple sets of reels decrease successively and are in the same gradient direction as the roller.

[0008] Furthermore, a mounting plate is arranged on the outer side of the shelf, and the roller is rotatably mounted between the mounting plates. A through opening is opened on the outer side of the shelf, and the bottom support member passes through the through opening.

[0009] Furthermore, a guide roller is rotatably mounted on the outer side of the through opening.

[0010] Furthermore, the cross section of the bracket is designed to be semi-circular, a plurality of groups of unloading rollers are rotatably mounted on the inner bottom of the bracket, and a baffle is provided at the bottom end of the bracket.

[0011] Furthermore, a mounting base is hinged at the bottom of the bracket, a telescopic drive is hinged at the top of the mounting base, and a telescopic end of the telescopic drive is hinged at the bottom of the bracket.

[0012] Furthermore, the bottom support is composed of an upper polypropylene film and a lower woven layer.

[0013] Furthermore, an elastic rope guide tube is arranged inside the inner coiled rope braided layer, and the inner coiled rope is arranged in the elastic rope guide tube.

[0014] Furthermore, a transmission sleeve is provided at one end of the roller away from the shelf exit, a transmission groove is provided on the inner wall of the transmission sleeve, a transmission sleeve is slidably connected to the outer side of the inner shaft rod, transmission protrusions are provided on the outer side and inner wall of the transmission sleeve, an electromagnet is fixedly installed on the outer side of the inner shaft rod, and a top spring is provided between the electromagnet and the transmission sleeve.

[0015] Furthermore, a driving motor is fixedly installed on the top of the shelf, and a driving shaft is fixedly installed on the output end of the driving motor. The driving shaft is composed of multiple groups of worm gears. A transmission head is arranged on the outer side of the inner shaft, and a worm wheel is rotatably installed on the outer side of the transmission head. The worm wheel is meshed with the worm gear. A driving sleeve is arranged on the side of the worm wheel close to the roller, and transmission grooves are provided on the inner wall of the driving sleeve and the outer side of the transmission head. A cavity is provided in the middle of the driving sleeve, and the outer diameter of the cavity is larger than the maximum width of the transmission sleeve. The cavity is located between the transmission head and the transmission outer sleeve.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention arranges multiple sets of trapezoidal bottom supporting parts and conical rollers. The rollers wind up the bottom supporting parts to lift the carpet. The bottom supporting parts on the top of the rollers can lift the carpet on the top and take out the carpet on the bottom. Therefore, the rolled carpets can be stacked and stored, and the space utilization rate is high.

[0018] 2. When the trapezoidal bottom support of the present invention is fully relaxed, the end close to the shelf exit is higher, so the rolled carpet can slide into the shelf along the bottom support and be stored obliquely in the shelf with high storage stability. When taking out, the inner shaft drives the reel to rotate, and the reel reels the inner reel rope. Due to the different reel radii, the end of the bottom support away from the shelf exit is higher. At this time, the rolled carpet automatically slides out obliquely downward, completing automatic storage and retrieval, and the storage and retrieval space utilization rate is high.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1, as Figure 1-Figure 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 stereoscopic warehouse, and the bracket 2 is installed on a stereoscopic warehouse stacker. Multiple groups of bottom brackets 3 are arranged from top to bottom inside the shelf 1. The bottom brackets 3 are trapezoidal in design, and the length of the side close to the exit of the shelf 1 is short. Multiple groups of inner coil ropes 31 are arranged inside the bottom brackets 3.

[0030] A roller 4 is rotatably installed on the outer side of the shelf 1. The roller 4 is conical in design and has a small radius at the end close to the exit of the shelf 1. The bottom support 3 is fixedly installed on the roller 4 at the side away from the shelf 1. An inner shaft rod 5 is rotatably installed inside the roller 4. Multiple groups of reels 6 are fixedly installed on the outer side of the inner shaft rod 5. An inner winding rope 31 is fixedly installed on the reel 6. The radii of the multiple groups of reels 6 decrease successively and are in 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 is in 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 slanting 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. 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 taking out the carpet, the winding roller 4 above the taken carpet is controlled to rotate, and the winding roller 4 reels in the bottom support member 3. Since the winding roller 4 is conical in design and has a small radius at the end close to the exit of the shelf 1, the winding distance of the end of the winding roller 4 close to the exit 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 taken carpet enough space. At the same time, the inner shaft rod 5 corresponding to the taken carpet is controlled to rotate, and the inner shaft rod 5 drives the multiple groups of winding wheels 6 to rotate simultaneously. It should be noted that the radius of the group of winding wheels 6 decreases successively and has the same gradient direction as the winding roller 4, but the gradient radius difference of the winding wheel 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 is 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 reel in the bottom support member 3 at this position, and the height difference control is achieved by the tension degree of the multiple groups of inner winding ropes 31. Figure 1After the rolled carpet is stored, its length exceeds the length of the shelf 1. Therefore, when it slides out obliquely downward, the lower end of the rolled carpet will not be located between the two sets of inner coiling ropes 31, and the inner coiling ropes 31 will not block it and it can slide downward stably. At this time, the bracket 2 is moved to the bottom of the bottom support member 3 by the three-dimensional warehouse stacker, and the end close to the bottom support member 3 is tilted upward, so that the rolled carpet can automatically slide down into the bracket 2, and the rolled carpet is automatically taken out, and the rolled carpet at any position can be taken out according to needs.

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

[0034] Embodiment 2, based on the above embodiment, further includes that a mounting plate 11 is provided on the outer side of the shelf 1, the roller 4 is rotatably mounted between the mounting plates 11, and a through opening 12 is opened on the outer side of the shelf 1, and the bottom support member 3 passes through the through opening 12.

[0035] Furthermore, a guide roller 13 is rotatably installed on the outer side of the through hole 12, and the arrangement of the guide roller 13 makes the winding of the bottom support member 3 more stable.

[0036] Embodiment 3, based on the above embodiment, further includes that the cross section of the bracket 2 is designed to be semi-circular, a plurality of groups of unloading rollers 21 are rotatably installed on the inner bottom of the bracket 2, and a baffle is provided at the bottom end of the bracket 2. The semi-circular design can better adapt to the rolled carpet, and the setting of the baffle ring can stably catch the rolled carpet that slides down.

[0037] Embodiment 4, based on the above embodiment, further includes: the bottom of the bracket 2 is hinged with a mounting base 22, the top of the mounting base 22 is hinged with a telescopic drive 23, and the telescopic end of the telescopic drive 23 is hinged to the bottom of the bracket 2.

[0038] This embodiment is more suitable for a three-dimensional warehouse stacker that only has lifting capabilities, so an additional telescopic drive 23 needs to be set to control the tilt of the bracket 2. The telescopic drive 23 can be a hydraulic cylinder, an electric telescopic rod or a cylinder, which can be selected according to the actual environment. If the three-dimensional warehouse stacker is a forklift, the bracket 2 can be directly installed on the fork rod of the forklift, and the forklift itself can adjust the tilt angle of the fork rod.

[0039] Embodiment 5, based on the above embodiment, further includes that the bottom support 3 is composed of an upper polypropylene film and a lower woven layer. Through this design, the rolled carpet can be stably supported while reducing the friction between the rolled carpet and the bottom support 3, making the placement more stable and the moisture-proof effect better.

[0040] Furthermore, an elastic guide rope tube is arranged inside the braided layer of the inner coil rope 31, and the inner coil rope 31 is arranged in the elastic guide rope tube. Through the arrangement of the elastic guide rope tube, when the bottom support member 3 is relaxed, a stable arc structure can be maintained, the rolled carpet can be stored more stably, and the inner coil rope 31 can be more stably rolled up relative to the bottom support member 3.

[0041] Embodiment 6, on the basis of the above embodiment, further includes: a transmission sleeve 41 is provided at the end of the roller 4 away from the exit of the shelf 1, a transmission groove is opened on the inner wall of the transmission sleeve 41, a transmission sleeve 54 is slidably connected to the outer side of the inner shaft rod 5, and transmission protrusions are provided on the outer side and inner wall of the transmission sleeve 54, an electromagnet 52 is fixedly installed on the outer side of the inner shaft rod 5, and a top spring 53 is provided between the electromagnet 52 and the transmission sleeve 54.

[0042] Furthermore, a driving motor 7 is fixedly installed on the top of the shelf 1, and a driving shaft 8 is fixedly installed on the output end of the driving motor 7. The driving shaft 8 is composed of multiple groups of worm gears. A transmission head 56 is arranged on the outer side of the inner shaft 5, and a worm wheel 51 is rotatably installed on the outer side of the transmission head 56. The worm wheel 51 is meshed with the worm gear. A driving sleeve 55 is arranged on the side of the worm wheel 51 close to the roller 4. Transmission grooves are provided on the inner wall of the driving sleeve 55 and the outer side of the transmission head 56. A cavity is provided in the middle of the driving sleeve 55. The outer diameter of the cavity is larger than the maximum width of the transmission sleeve 54, and the cavity is located between the transmission head 56 and the transmission outer sleeve 41.

[0043] It should be noted that when the electromagnet 52 is not energized, the transmission sleeve 54 spans between the drive sleeve 55 and the transmission outer sleeve 41, and the worm gear 51 can drive the roller 4 to rotate. When the electromagnet 52 is energized, there are two gears. When taking out the carpet, the electromagnet 52 on the inner shaft 5 corresponding to the taken carpet is controlled to be energized to the second gear, and the electromagnet 52 drives the transmission sleeve 54 to slide out of the transmission outer sleeve 41 through magnetic force. At the same time, 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 enables the worm gear 51 to drive the inner shaft 5 to rotate. At the same time, the electromagnet 52 under the taken carpet is energized to the first gear, and the transmission sleeve 54 slides to the cavity position of the drive sleeve 55. In other words, the worm gear 51 at the taken position can drive the inner shaft 5 to rotate, the upper worm gear 51 drives the roller 4 to rotate, and the lower worm gear 51 rotates idly.

[0044] At this time, the driving motor 7 is controlled to rotate, and the driving motor 7 drives all the worm wheels 51 to rotate simultaneously through the worm, and the worm wheel 51 above the taken carpet drives the roller 4 to rotate through the inner shaft 5, the transmission sleeve 54 and the transmission outer sleeve 41, and the roller 4 rewinds the bottom support 3. Since the roller 4 is conical in design and the radius is small at the end close to the exit of the shelf 1, the rewinding distance of the end of the roller 4 close to the exit of the shelf 1 is short. When the bottom support 3 is straightened, the heights of the two ends of the bottom support 3 are consistent, and the carpet above is lifted to the horizontal level, giving enough space for the taken carpet, and the carpet below remains unchanged. At the same time, the inner shaft rod 5 corresponding to the taken carpet rotates, and the inner shaft rod 5 drives the multiple groups of winding wheels 6 to rotate simultaneously. It should be noted that the radius of the group of winding wheels 6 decreases successively, and has the same gradual change direction as the winding roller 4, but the gradual change radius difference of the winding wheel 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 is still in a relaxed state. The inner winding rope 31 makes one end of the rolled carpet inside the shelf 1 higher than the other end. It should be noted that at this position, the winding roller 4 does not reel in the bottom support 3, and the height difference is controlled by the tightening degree of the multiple groups of inner winding ropes 31. Figure 1 After the rolled carpet is stored, its length exceeds the length of the shelf 1. Therefore, when it slides out obliquely downward, the lower end of the rolled carpet will not be located between the two sets of inner coiling ropes 31, and the inner coiling ropes 31 will not block it and it can slide downward stably. At this time, the bracket 2 is moved to the bottom of the bottom support member 3 by the three-dimensional warehouse stacker, and the end close to the bottom support member 3 is tilted upward, so that the rolled carpet can automatically slide down into the bracket 2, and the rolled carpet is automatically taken out, and the rolled carpet at any position can be taken out according to needs.

[0045] Therefore, through the configuration of this embodiment, all controls can be achieved by simply configuring a set of drive motors 7, and through the worm gear one-way transmission structure design, when the drive motor 7 is powered off, the overall state remains stable, and the structure is simple and compact.

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