Description

Technical Field

[0001] The present invention relates to a fabric conveying device, and more particularly, to a fabric unpacking and conveying device and a conveying line based on the device. Background Technology

[0002] Currently, in places like hospitals, hotels, and dormitories where multiple people stay for short periods, it is necessary to centrally clean and wash used clothing, sheets, duvet covers, and other fabrics. During collection, cleaning staff often mix various fabrics together and pack them in sheets for convenience, resulting in all the fabrics being piled up and tangled together, making it difficult to separate and wash them. In the existing fabric recycling and cleaning process, the tangled fabrics are usually separated manually and placed into the next process step. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a compact, automated fabric dispersing and conveying device and a conveying line based on the device.

[0004] The technical solution of the present invention is implemented as follows: a fabric dispersing and conveying device includes a frame, a material collection hopper is provided on one side of the frame, a clearance notch is provided at the bottom of the material collection hopper and on one side therein, a circulating material picking mechanism is provided on the frame near the clearance notch, and a material picking rod assembly that cooperates with the clearance notch is provided on the circulating material picking mechanism.

[0005] A material output unit is installed on the frame on one side of the hopper along the forward direction of the circulating material picking mechanism. The material in the hopper is randomly picked up by the picking rod assembly and transported to the material output unit.

[0006] In the aforementioned fabric dispersing and conveying device, when the material picking rod assembly moves above the material output unit, it tilts, and the material on the material picking rod assembly falls into the material output unit; when the material picking rod assembly moves to an area outside the material output unit, the material picking rod assembly is in a horizontal state.

[0007] In the above-mentioned fabric dispersing and conveying device, the collecting hopper includes two vertical side plates arranged opposite each other, and a guide side plate is connected between the corresponding ends of the two vertical side plates. The guide side plate is shaped with a larger top and a smaller bottom.

[0008] A base plate is provided at the bottom of each vertical side plate and each guide side plate. The clearance notch is provided on the base plate and the vertical side plate near the circulating material picking mechanism. The length of the clearance notch on the base plate is adapted to the length of the part of the hanging rod on the picking rod assembly that extends into the hopper.

[0009] In the above-mentioned fabric dispersing and conveying device, brush strips are symmetrically and detachably installed at the clearance gap; in the initial state, the symmetrically installed brush strips close the clearance gap, and when picking up materials, the picking rod assembly pushes open the brush strips and passes through the clearance gap into the collection hopper.

[0010] In the aforementioned fabric dispersing and conveying device, the circulating material picking mechanism includes a mounting bracket set on the side frame of the collecting hopper, and a ring drive mechanism is set on the mounting bracket. There are several material picking rod assemblies that are spaced apart on the ring drive mechanism. The running trajectory of the ring drive mechanism located on the side of the clearance gap is parallel to the clearance gap.

[0011] A guide rail for the picking rod assembly is provided on the side of the ring drive mechanism; the guide rail and the picking rod assembly work together to make the picking rod on the picking rod assembly tilted when it is above the material output unit, and horizontal in other areas.

[0012] In the aforementioned fabric dispersing and conveying device, the annular drive mechanism includes at least four sets of sprockets. Each set of sprockets consists of a horizontal linkage shaft mounted on a mounting bracket via bearings and sprockets fixedly connected to both ends of the horizontal linkage shaft. A drive chain is connected between each cooperating sprocket, and one set of sprockets is connected to a drive motor. The material picking rod assembly is disposed between two drive chains. The drive chains are rectangular, and the top drive chain is horizontal.

[0013] In the aforementioned fabric dispersing and conveying device, the material picking rod assembly includes a connecting seat fixed on a ring drive mechanism, and a limiting baffle is vertically and symmetrically arranged on the long edge of the connecting seat. The end of the limiting baffle near the collecting hopper extends to the outside of the ring drive mechanism.

[0014] A hanging rod is hinged to the end of the limiting baffle near the hopper; the front end of the hanging rod is suspended and adapted to the clearance notch, and the rear end is matched with the hanging rod guide rail.

[0015] When the hanging rod is located at the upper end of the ring drive mechanism, the hanging rod is not constrained by the position baffle, and the rear end of the hanging rod moves along the hanging rod guide track and tilts the hanging rod.

[0016] When the hanging rod leaves the upper end of the ring drive mechanism, the hanging rod remains horizontal due to the restriction of the limiting baffle and the hanging rod guide rail or the ring drive mechanism.

[0017] In the aforementioned fabric dispersing and conveying device, the hanging rod guide rail consists of a flipping guide section located above the material output unit and having an upwardly arched arc shape, and a limiting guide section connected to both ends of the flipping guide section and parallel to the rectangular drive mechanism.

[0018] The flipping guide section and the limiting guide section are integrally formed structures made of hollow round tubes or solid round wires; a guide roller that cooperates with the guide rail of the hanging rod is rotatably connected to the rear end of the hanging rod.

[0019] In the above-mentioned fabric dispersing and conveying device, the flipping guide section includes an upwardly inclined rising section, and a downwardly inclined reset section is connected at the highest point of the rising section; the position of the highest point of the rising section is located directly above the center of the material output unit.

[0020] With the above structure, the material in the hopper is randomly picked up and transported to the material output unit by the material picking rod assembly and the circulating material picking mechanism. When the fabric stacked and wrapped in the hopper is picked up, the fabric that cannot be hung on the material picking rod assembly will slide to the side under its own weight, so that the wrapped fabric reaches a loose state and the wrapped fabric is separated as much as possible.

[0021] A conveyor line based on any of the above-described conveying devices, the conveyor line comprising at least two sets of conveying devices connected in sequence, wherein an elevator is connected to the material output unit of each conveying device to cooperate with the collection hopper of the next conveying device; the length of the picking rod on each conveying device gradually decreases, and the size of the collection hopper cooperating with the picking rod also gradually decreases.

[0022] With the above-described structure, this invention uses at least two sequentially connected conveying devices to repeatedly lift and convey the fabric, allowing it to be fully separated into individual pieces. Simultaneously, the size of the collecting hopper gradually decreases, causing the fabric to gradually gather during conveying. When the fabric reaches the end of the conveying process, it is presented as a relatively clustered individual piece, facilitating subsequent equipment or manual handling.

[0029] See Figure 1-3 As shown, a fabric dispersing and conveying device of the present invention includes a frame 1, a collecting hopper 2 is provided on one side of the frame 1, and a clearance notch 3 is provided at the bottom and one side of the collecting hopper 2. In this embodiment, the collecting hopper 2 includes two vertical side plates 2a arranged opposite each other, and a guide side plate 2b is connected between the corresponding ends of the two vertical side plates 2a. The guide side plate 2b is shaped with a larger top and a smaller bottom. The guide side plate adopts a cross-section with a rectangular top and an inverted trapezoidal bottom, which can gather the fabric towards the clearance notch in the middle and prevent the fabric from falling onto the bottom plate at the dead corner on both sides of the clearance notch.

[0030] Preferably, brush strips 7 are symmetrically and detachably installed at the clearance notch 3. In the initial state, the symmetrically installed brush strips 7 close the clearance notch 3. When picking up material, the picking rod assembly 5 pushes open the brush strips 7 and passes through the clearance notch 3 into the collection hopper 2. By setting the brush strips to close the clearance notch in the initial state, it is possible to prevent the fabric from falling out of the collection hopper from the clearance notch.

[0031] A circulating material picking mechanism 4 is provided on the frame 1 near the clearance gap 3, and a material picking rod assembly 5 that cooperates with the clearance gap 3 is provided on the circulating material picking mechanism 4.

[0032] A base plate 2c is provided at the bottom of each vertical side plate 2a and each guide side plate 2b. The clearance notch 3 is provided on the base plate 2c and the vertical side plate 2a near the circulating material picking mechanism 4. The length of the clearance notch 3 on the base plate 2c is adapted to the length of the part of the hanging rod on the picking rod assembly 5 that extends into the collection hopper 2. The length of the clearance notch on the base plate is at least 0.8 times the length of the entire base plate, and the front end of the hanging rod on the picking rod assembly can be as close as possible to the vertical side plate on the other side to ensure that the fabric can be hung on the hanging rod.

[0033] A material output unit 6 is provided on the frame 1 on one side of the hopper 2 along the forward direction of the circulating material picking mechanism 4. The material in the hopper 2 is randomly picked up by the picking rod assembly 5 and transported to the material output unit 6.

[0034] In this embodiment, when the material picking rod assembly 5 moves above the material output unit 6, it tilts, and the material on the material picking rod assembly 5 falls into the material output unit 6. When the material picking rod assembly is tilted, the angle between it and the horizontal plane is 60-90°. By setting a large tilt angle, it can be ensured that the fabric hanging on the material picking rod assembly can fall smoothly and quickly onto the material output unit below. When the material picking rod assembly 5 moves to an area outside the material output unit 6, the material picking rod assembly 5 is in a horizontal state.

[0035] In this embodiment, the circulating material picking mechanism 4 includes a mounting bracket 4a disposed on the side frame 1 of the collecting hopper 2. A ring drive mechanism 8 is disposed on the mounting bracket 4a. Several material picking hook assemblies 5 are distributed at intervals on the ring drive mechanism 8. The running trajectory of the ring drive mechanism 8 located on the side of the clearance notch 3 is parallel to the clearance notch 3. The arrangement of several material picking hook assemblies on the ring drive mechanism enables continuous material picking, effectively improving the conveying efficiency.

[0036] The annular drive mechanism 8 includes at least four sets of sprocket groups 8a. Each set of sprocket groups 8a consists of a horizontal linkage shaft 8b mounted on a mounting bracket 4a via bearings and sprockets 8c fixedly connected to both ends of the horizontal linkage shaft 8b. The length of the horizontal linkage shaft is between 40-60 cm. A drive chain 8d is connected between each cooperating sprocket 8c, and one set of sprocket groups 8a is connected to a drive motor 8e. The material picking rod assembly 5 is positioned between two drive chains 8d. The drive chains 8d are rectangular, and the top drive chain 8d is horizontal. The horizontal orientation of the top drive chain facilitates the rotation of the picking rod. The annular drive mechanism can also employ other structures commonly used in the art, such as belts or chain plates instead of chains.

[0037] A rod guide rail 4b is provided on the side of the ring drive mechanism 8 to cooperate with the material picking rod assembly 5; the rod guide rail 4b and the material picking rod assembly 5 cooperate to make the rod on the material picking rod assembly 5 tilted when it is above the material output unit 6, and horizontal in other areas.

[0038] In this embodiment, the material picking rod assembly 5 includes a connecting seat 5a fixed on the annular drive mechanism 8, and a limiting baffle 5b is vertically and symmetrically arranged on the long side edge of the connecting seat 5a. The end of the limiting baffle 5b near the collecting hopper 2 extends to the outside of the annular drive mechanism 8.

[0039] A hanging rod 5c is hinged to the end of the limiting baffle 5b near the collecting hopper 2. The front end of the hanging rod 5c is suspended and conforms to the clearance notch 3, while the rear end engages with the hanging rod guide rail 4b. The hinge point between the limiting baffle and the hanging rod is located outside the annular drive mechanism, ensuring that the hanging rod can rotate up to 90° to a vertical position when it reaches the material output unit. The distance between the rear end of the hanging rod and the hinge point is at least half the distance between the front end of the hanging rod and the hinge point, and the distance between the rear end of the hanging rod and the hinge point is adapted to the length of the horizontal linkage shaft. The hanging rod hinges to the limiting baffle to form a lever, and the length of the rear lever arm is half or more of the length of the front lever arm, ensuring that the rear end engaging with the hanging rod guide rail will not be subjected to excessive force when the front end of the hanging rod lifts the fabric.

[0040] When the hanging rod 5c is at the upper end of the ring drive mechanism 8, the hanging rod 5c is not constrained by the limiting baffle 5b, and the rear end of the hanging rod 5c moves along the hanging rod guide rail 4b, causing the hanging rod 5c to tilt. When the hanging rod 5c leaves the upper end of the ring drive mechanism 8, the hanging rod 5c is kept horizontal by the limiting baffle 5b and the hanging rod guide rail 4b or the ring drive mechanism 8. The rear end of the hanging rod moves along the hanging rod guide rail, and the hinge point between the middle of the hanging rod and the limiting baffle allows the hanging rod to tilt, without the need for an additional drive unit to provide power for the rotation of the hanging rod.

[0041] The hanging rod guide rail 4b consists of a flipping guide section 4c located above the material output unit 6 and having an upward arched arc shape, and a limiting guide section 4d connected to both ends of the flipping guide section 4c and parallel to the annular drive mechanism 8.

[0042] The flipping guide section 4c and the limiting guide section 4d are integrally formed structures made of hollow round tubes or solid round wires; a guide roller 4e that cooperates with the guide rail 4b is rotatably connected to the rear end of the hanging rod 5c. The guide roller can reduce the friction between the rear end of the hanging rod and the guide rail, thereby reducing wear on the rear end of the hanging rod and the guide rail.

[0043] In this embodiment, the flipping guide section (4c) includes an upwardly inclined rising section, with a downwardly inclined reset section connected at the highest point of the rising section; the highest point of the rising section is located directly above the center of the material output unit (6). When the guide roller rises along the rising section, the hanging rod tilts downward, and when it reaches the highest point, the fabric slides off the hanging rod.

[0044] The rising amplitude and the position of the highest point of the ascending section are set according to the position of the material output unit. When the guide roller reaches the highest point of the ascending section, the angle between the hanging rod and the horizontal plane is 60-90°. The tilt angle of the hanging rod does not exceed 45° before it enters the area above the material output unit to prevent the fabric from falling prematurely outside the material output unit. To further prevent the fabric from falling prematurely outside the material output unit, it is preferable to set the material output unit close to the collecting hopper.

[0045] During operation, the fabric is temporarily stored in the collection hopper via an external conveyor. The hanging rod moves along the drive chain and enters the collection hopper from below through a clearance to pick up the fabric. When the hanging rod moves to the top along the drive chain, the guide roller moves upward along the flipping guide section of the hanging rod guide track, causing the front end of the hanging rod to tilt downward and slide the fabric onto the material output unit.

[0046] See Figure 4 As shown, a conveyor line based on any of the above-described conveying devices according to the present invention includes at least two sets of conveying devices connected in sequence. A hoist 9, cooperating with the collection hopper 2 of the subsequent conveying device, is connected to the material output unit 6 of each conveying device. The length of the picking rod 5c on each conveying device gradually decreases, and the size of the collection hopper 2 cooperating with the picking rod 5c also gradually decreases. By repeatedly lifting and conveying the fabric through at least two sets of sequentially connected conveying devices, the fabric can be fully separated into individual pieces.

[0047] Meanwhile, the length of the material picking rod and the size of the material collecting hopper gradually decrease, causing the fabric to gradually gather during the conveying process. When the fabric is conveyed to the end, it is in a relatively gathered state, which makes it convenient for subsequent equipment or personnel to grab the fabric.

[0048] The above-described embodiments are preferred embodiments of the present invention and are only used to facilitate the illustration of the present invention. They are not intended to limit the present invention in any way. Any person skilled in the art who makes local modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
