Description

Technical Field

[0001] The present invention relates to the field of cargo handling equipment, and more specifically, to a handling equipment with a cleaning function.

Background Art

[0002] Handling equipment is widely used in various fields, and in the food production line, it is often used for connecting the two processes before and after. For example, handling equipment is also indispensable in the sake lees brewing process. Sake lees, which is a by-product in the liquor brewing process and is also called sake kasu or sake dregs, mainly consists of yeast remaining after fermentation, unfermented sugar, alcohol and some solid substances, and is usually generated during the brewing of beer, wine or other liquors.

[0003] In the conveying process of sake lees, sake lees liquid or cooked rice often adheres to the conveyor belt, and may adhere to the surface of the transfer roller during transportation, causing contamination of the sake lees. Therefore, cleaning of the conveyor belt is required. In the prior art, in the equipment for conveying sake lees, a scraper is provided on the conveyor belt to remove the remaining dirt or foreign matter of sake lees, and then the conveyor belt is scraped by a cleaning brush. However, since there is a relatively large gap on the conveyor belt between the scraper and the brush, the scraped conveyor belt may not be quickly cleaned by the brush when passing through the brush, and dirt may remain and dry. In addition, in one cycle, the brush and the scraper are usually cleaned only once, which is disadvantageous for improving the cleanliness of the conveyor belt. Furthermore, in some equipment, since the scraper and the brush need to be arranged avoiding the frame of the equipment, the dirt removed by the brush or the scraper is likely to remain at the corners of the frame of the equipment, leading to the breeding of bacteria, which is also disadvantageous for improving the hygiene of the conveyor belt.

Summary of the Invention

[0004] The conveying equipment with a cleaning function of the present invention can effectively solve the problems that hinder the improvement of cleanliness and hygiene during use of the conveyor belt in the above-mentioned existing conveying devices.

[0005] According to one aspect of the present invention, a conveying device with a cleaning function is provided, and the conveying device with a cleaning function is A support rack on which transfer rollers are rotatably arranged, A conveyor belt fitted onto the aforementioned transfer roller and driven by the aforementioned transfer roller to transport, The support rack comprises a cleaning mechanism integrally arranged on one side of the support rack, During one cycle of conveyance on the conveyor belt, the cleaning mechanism simultaneously performs multiple alternating cleaning and scraping operations on the conveyor belt, and the cleaned foreign matter on the conveyor belt is collected within the cleaning mechanism. The cleaning mechanism is A water collection frame is positioned on one side of the aforementioned support rack, Multiple scraping devices are arranged on the water collection frame to scrape the surface of the conveyor belt, The system comprises a plurality of washing rollers rotatably positioned on the water collection frame and in contact with the conveyor belt, so as to wash the surface of the conveyor belt by rolling over it. In the conveying direction of the conveyor belt, the multiple scraping devices are arranged adjacent to the washing rollers and alternately, and foreign matter washed from the conveyor belt by the scraping devices and the washing rollers is collected in the water collection frame. Thus, the water collection frame collects the removed foreign matter and enables scraping by the scraping devices and washing by the washing rollers. Since the removal structure is integrated into the water collection frame, interference with other components is less likely to occur.

[0006] In some embodiments, the scraping device is A reciprocating lead screw rotatably positioned on the water collection frame, A limit slide bar is positioned on the water collection frame and adjacent to the reciprocating lead screw, The system comprises a reciprocating lead screw and a plurality of drive blocks movably arranged on the limit slide bar and equipped with scrapers, The rotation of the reciprocating lead screw moves the drive block along the limit slide bar, causing the scraper to scrape the surface of the conveyor belt. The direction of movement of the scraper is perpendicular to the conveying direction of the conveyor belt.

[0007] The conveying equipment with a cleaning function according to claim 2, characterized in that the scraper has a scraping surface that contacts the conveyor belt, a scraping gap is provided on the scraping surface, and when the scraper moves the scraping surface to scrape the surface of the conveyor belt, the scraped foreign matter is separated from the scraping gap. Accordingly, the reciprocating lead screw is used to move the scraper by moving the drive block, and the limit slide bar is used to limit the direction of movement of the drive block to achieve the scraping operation.

[0008] In some embodiments, the cleaning mechanism further comprises a transmission unit, and the transmission unit is A drive unit is positioned on the water collection frame, with its output terminal connected to the washing roller, A synchronous wheel coaxially arranged on the aforementioned cleaning roller, A driven wheel coaxially arranged on the limit slide bar, The system comprises a synchronous wheel and a synchronous belt that is scalably connected to the driven wheel, By driving the cleaning roller to rotate using the aforementioned drive device, the synchronous belt rotates the synchronous wheel and the driven wheel, and as the reciprocating lead screw rotates, the scraper moves along the surface of the conveyor belt. The synchronous belt transmittably connects two adjacent synchronous wheels, the driven wheel is positioned between the two adjacent synchronous wheels, and the synchronous belt rotates the driven wheel through the meshing of gears and racks. Thus, the drive unit is used to supply a power source that enables the motion of the synchronous wheels, the driven wheel, and other components by the synchronous belt.

[0009] In some embodiments, the transmission unit further comprises a pressing plate positioned on the water collection frame, the pressing plate contacting both sides of the synchronous belt, thereby bringing the synchronous belt into close contact with the synchronous wheel and the driven wheel. Thus, the pressing plate is used to ensure the effectiveness of power transmission by the synchronous belt and to avoid the transmission becoming ineffective.

[0010] In some embodiments, the cleaning mechanism further comprises a wash-off section located on the water collection frame, the wash-off section being A first flusher equipped with multiple nozzles for spraying detergent, A second flusher equipped with multiple nozzles for spraying cleaning solution, The output terminal of the device is connected to the first flasher and the second flasher, and the device includes a pressurizing device that pressurizes the first flasher and the second flasher to perform a spraying operation, In the conveying direction of the conveyor belt, the first flusher and the second flusher are sequentially positioned upstream of the cleaning roller. Therefore, the spray cleaning effect of the first and second flushers is achieved via a pressurizing device, and the conveyor belt proceeds to the scraping and cleaning process after undergoing spray cleaning, thereby enhancing the effectiveness of the cleaning.

[0011] In some embodiments, the flushing section further comprises a baffle plate, which has arc-shaped walls surrounding both sides of the first flusher and preventing the detergent from the first flusher from entering the conveyor belt from either side. Thus, the baffle plate is used to prevent the detergent from entering the output side of the conveyor belt and to avoid contamination of the conveyed cargo.

[0012] In some embodiments, an exhaust fan for driving hot air is provided on the water collection frame, the direction of the airflow generated by the exhaust fan is directed toward the conveyor belt, and in the conveying direction of the conveyor belt, the exhaust fan is positioned downstream of the washing roller. The water collection frame is provided with drainage holes, and the bottom of the water collection frame is recessed and converges toward the drainage holes. Therefore, the exhaust fan is used to dry the conveyor belt so that it is kept dry and clean before it enters transport, and the drainage holes are useful for removing foreign matter from the water collection frame and for reuse.

[0013] In some embodiments, in the conveying direction of the conveyor belt, the conveyor belt is recessed from both sides toward the center to form a conveying recess, and the washing rollers protrude from both sides toward the center and contact the recess. Thus, the recess can convey the cargo and prevent the cargo from falling out.

[0014] In some embodiments, limit rollers are provided on the support rack, and the limit rollers contact the surface of the conveyor belt at an angle, causing the conveyor belt to form the recess.

[0015] On both sides of the transfer roller, contact inclined surfaces are provided. The inclination of the contact inclined surface is the same as that of the limit roller. The conveyor belt receives force between the contact inclined surface and the limit roller. Therefore, the conveyor belt is restricted by the limit roller and the contact inclined surface to ensure the effectiveness of the recess.

[0016] The conveying equipment with a cleaning function of the present invention has the following beneficial effects compared with the prior art.

[0017] The conveyor belt of the present application undergoes surface cleaning treatment by a cleaning mechanism during conveying. Since the cleaning mechanism is integrated on one side of the support rack, interference between the cleaning mechanism and the support rack or other components can be avoided. In addition, the cleaning mechanism can simultaneously perform multiple and alternating cleaning operations and scraping operations on the conveyor belt. By repeated cleaning and scraping, the effectiveness of cleaning the conveyor belt can be ensured, which helps to improve the cleanliness and hygiene during the use of the conveyor belt. Since the washed foreign matters are collected into the cleaning mechanism, it is possible to avoid the removed foreign matters from falling onto the support rack and make it difficult for residual foreign matters to increase.

Embodiments for Carrying out the Invention

[0019] To further clarify the object, technical solution, and advantages of the embodiments of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below, together with the drawings of the embodiments. Naturally, the embodiments described are only some, not all, embodiments of the present invention. All other embodiments obtained based on the embodiments of the present invention without the creative effort of a person skilled in the art will all fall within the scope of the protection of the present invention.

[0020] Furthermore, the terms “first” and “second” are for descriptive purposes only and should not be understood as indicating or suggesting relative importance or implying the number of technical features shown. Therefore, the features defining “first” and “second” may explicitly or implicitly include at least one such feature. In this description of the invention, unless otherwise clearly and specifically defined, “multiple” means at least two, for example, two, three.

[0021] This invention relates to a conveying system with a cleaning function, applicable to the field of food processing and conveying technology, particularly to the manufacturing process of sake lees. This conveying system possesses both a normal conveying function and a cleaning function, thereby ensuring cleanliness in the food processing process during use.

[0022] The present invention will be described in more detail below with reference to the drawings.

[0023] Figure 1 schematically shows a conveying device with a cleaning function according to one embodiment of the present invention. As shown in Figure 1, the side facing the direction of gravity is considered the bottom, the opposite side is considered the top, the length direction of this conveying device with a cleaning function is the left-right direction, and the width direction of this conveying device with a cleaning function is the front-back direction. This conveying device with a cleaning function comprises a support rack 1, a conveyor belt 3, and a cleaning mechanism 4.

[0024] The support rack 1 employs a rectangular frame structure for supporting other members. The support rack 1 may be constructed as a welded rack. Four support legs 11 are provided at the bottom of the support rack 1. The support legs 11 may be placed on a horizontal plane and may be fixed or movable. For example, the support legs 11 may be equipped with a swivel pulley to facilitate movement to other positions. A hollow structure is provided within the support rack 1 for rotatably arranging the transfer rollers 2. There are preferably multiple transfer rollers 2. The multiple transfer rollers 2 are arranged along the length of the support rack 1, and the axial direction of the transfer rollers 2 extends in the width direction. The transfer rollers 2 are specifically electric transfer rollers and, when energized, can be driven to provide power for transporting cargo. A conveyor belt 3 is fitted onto the transfer rollers 2 so that the transfer rollers 2 can drive the motion of the conveyor belt 3.

[0025] As shown in Figure 2, the conveyor belt 3 rotates along its length and transports goods when driven by the transport rollers 2. Because the conveyor belt 3 can rotate periodically, goods can be transported on the conveyor belt 3. In this embodiment, the upper transport direction of the conveyor belt 3 is transport direction A (leftward direction), which is the direction in which goods are transported. The lower transport direction of the conveyor belt 3 is transport direction B (rightward direction), which is the direction in which the conveyor belt 3 turns back after transporting goods. Furthermore, since the goods being transported (for example, sake lees) may be liquid, the conveyor belt 3 is provided with recesses 31, which are recessed structures formed on the conveyor belt 3, in order to ensure the effectiveness of transport. In transport direction A, the conveyor belt 3 is recessed from both sides in the width direction along its center, forming recesses 31 for transporting goods. When viewed from the side, the recesses 31 are distributed on both the upper and lower sides of the conveyor belt 3. The recess 31 creates a structure in which the conveyor belt 3 is higher on both sides and lower in the center, meaning that the height of the front and rear sides is higher than the height of the center. Since the center of the conveyor belt 3 remains flat, the position of the cargo can be restricted during transport.

[0026] Specifically, as shown in Figure 3, the recess 31 is formed to be limited by the structure of the limit roller 12 and the transfer roller 2. The limit roller 12 is rotatably mounted on the support rack 1. The limit roller 12 is arranged mirror-symmetrically in the vertical and front-rear directions. The limit roller 12 is mounted at an inclination on the support rack 1, that is, the axis of the limit roller 12 intersects the axis of the transfer roller 2 in the axial direction. In order to conform to the shape of the conveyor belt 3, the transfer roller 2 also has a structure that is wide on both sides and narrow in the center. The diameter of the central part of the transfer roller 2 is smaller than the diameter of the sides. Furthermore, the transfer roller 2 is also provided with contact inclined surfaces 21, which are arranged mirror-symmetrically on both sides in the front-rear direction. The inclination of the contact inclined surfaces 21 is the same as the inclination of the limit roller 12. The limit roller 12 is positioned closer to the contact inclined surfaces 21. When the conveyor belt 3 is fitted onto the transfer roller 2, the inner surface of the conveyor belt 3 comes into contact with the contact inclined surfaces 21. Simultaneously, the upper and lower limit rollers 12 work in cooperation with the contact inclined surface 21 to restrict the position of the conveyor belt 3. Due to the symmetrical restriction of the left and right limit rollers 12, the conveyor belt 3 experiences force between the contact inclined surface 21 and the limit rollers 12. In this way, the conveyor belt 3 is recessed towards the center, forming a recess 31. This effectively prevents cargo from falling off the conveyor belt 3 as it passes through the recess 31, helping to improve the conveying efficiency of the conveyor belt 3.

[0027] As shown in Figure 4, the cleaning mechanism 4 is used to clean the conveyor belt 3 during transport, and can simultaneously perform multiple alternating cleaning and scraping operations on the conveyor belt 3. Since the cleaning mechanism 4 is integrally positioned on the underside (bottom) of the support rack 1, interference with other transport members is less likely to occur. Specifically, the cleaning mechanism 4 comprises a water collection frame 41, a washing section, a scraping device, a cleaning roller 44, and a transmission section.

[0028] The water collection frame 41 is a hollow frame used to collect dirt or foreign matter (for example, foreign matter formed from sake lees liquid and cooked rice) removed from the conveyor belt 3. The water collection frame 41 can be fixedly or detachably connected to the bottom of the support rack 1. The washing section, scraping device, washing roller 44, and transmission section are all integrally arranged on the water collection frame 41. The above mechanisms are mainly located on the left side of the water collection frame 41. The right side of the water collection frame 41 is open, making cleaning and inspection of the internal condition easier. A drain port 411 is provided at the bottom of the water collection frame 41. Preferably, the bottom of the water collection frame 41 is recessed to converge towards the drain port 411, so that foreign matter collected within the water collection frame 41 can be discharged from the drain port 411 by gravity. A conduit is usually connected to the outside of the drain port 411, making it easy to discharge to the outside or to reuse the foreign matter.

[0029] As shown in Figure 4, the flushing section is used to flush the conveyor belt 3 and is the first step in the conveyor belt 3 cleaning process. The flushing section is located on the leftmost side of the water collection frame 41. The flushing section comprises a first flusher 421, a second flusher 422, a pressurizing device, and a baffle plate 424. The first flusher 421 and the second flusher 422 extend along the width direction. Both the first flusher 421 and the second flusher 422 are equipped with multiple nozzles facing upward to facilitate direct action on the conveyor belt 3. The pressurizing device is specifically a pressurizing pump 423. An external connecting rack 412 extends to the left side of the water collection frame 41. The pressurizing pump 423 is mounted on the external connecting rack 412. The output terminals of the pressurizing pump 423 are connected to the first flusher 421 and the second flusher 422. A detergent storage tank is connected to the first flusher 421, and a washing water storage tank is connected to the second flusher 422. When the pressurizing pump 423 starts operating, it pressurizes and drives the first flusher 421 to spray detergent onto the conveyor belt 3, and drives the second flusher 422 to spray washing water upward to wash the conveyor belt 3. In the conveying direction B, the first flusher 421 is located upstream of the second flusher 422, and the second flusher 422 is located upstream of the washing roller 44. Therefore, the conveyor belt 3 passes through the first flusher 421 and the second flusher 422 in sequence before reaching the washing roller 44, completing the washing operation in stages. There may be two baffle plates 424, each fixed to the inner wall of the water collection frame 41 and arranged in a sealed manner. As a result, the first flasher 421 and the second flasher 422 are exposed from between the baffle plates 424. The baffle plates 424 have arc-shaped walls and form a hollow internal structure that can surround the sides of the first flasher 421 or the second flasher 422, so that the first flasher 421 and the second flasher 422 act directly on the surface of the conveyor belt 3.Furthermore, the baffle plate 424 prevents the detergent from the first flusher 421 from entering the conveyor belt 3 from both the front and back sides, thereby preventing contamination of the sake lees and helping to improve hygiene during transport on the conveyor belt 3.

[0030] The cleaning roller 44 is rotatably positioned on the water collection frame 41 and is used to contact the surface of the conveyor belt 3 and to roll and clean the surface of the conveyor belt 3. The axis of the cleaning roller 44 extends in the width direction. Multiple cleaning rollers 44 are provided to perform multiple cleaning operations on the conveyor belt 3. In this embodiment, four cleaning rollers 44 are provided and are evenly arranged along the conveying direction B. To conform to the structure of the recess 31 of the conveyor belt 3, the cleaning roller 44 is adopted to have a structure that is narrow on both sides and wide in the center, that is, the diameter of the cleaning roller 44 on both sides is larger than the diameter of the center, so that the cleaning roller 44 forms a protruding structure. The axial length of the central part of the cleaning roller 44 conforms to the width dimension of the recess 31. Preferably, the conveyor belt 3 needs to be cleaned again by the cleaning roller 44 when it undergoes the final scraping operation. That is, the cleaning operation of the cleaning roller 44 is the final surface contact treatment. In this embodiment, the cleaning roller 44 operates first after the liquid is sprayed onto the conveyor belt 3. After alternating cleaning, the cleaning operation is completed by using the next cleaning roller 44, thereby ensuring the cleanliness of the conveyor belt 3. The cleaning rollers 44 rotate mainly via the transmission section.

[0031] As shown in Figures 5 and 6, the transmission unit is used to provide the power necessary for the work of the cleaning rollers 44 and the scraping device. The transmission unit comprises a drive unit 451, synchronous wheels 452, driven wheels 453, a synchronous belt 454, and a pressure plate 455. The drive unit 451 is located on one side of the water collection frame 41 and is used as the power source for the transmission unit. The drive unit 451 is specifically a drive motor. The output end of the drive unit 451 is connected to the cleaning rollers 44 and drives them to rotate. The synchronous wheels 452 are arranged coaxially on the cleaning rollers 44. Two synchronous wheels 452 are provided at each end of one cleaning roller 44. The synchronous belt 454 is ductilely connected to two adjacent synchronous wheels 452. When the cleaning rollers 44 rotate, it rotates the synchronous belt 454 via the synchronous wheels 452. The synchronous belt 454 rotates the other cleaning roller 44. Of these, two adjacent cleaning rollers 44 are driven via at least one synchronous belt 454, thus rotating all cleaning rollers 44. A driven wheel 453 is positioned within the synchronous belt 454. The driven wheel 453 is preferably a gear structure that can drive and rotate by meshing with the gears and racks of the synchronous belt 454. The driven wheel 453 is used to move the scraping device and perform the scraping operation. A pressure plate 455 is positioned on the inner wall of the water collection frame 41. The pressure plate 455 has a plate-like structure, extends along the width direction, and can cover a portion of the synchronous belt 454. The pressure plate 455 abuts against both the upper and lower sides of the synchronous belt 454, i.e., two corresponding pressure plates 455 are provided on one synchronous belt 454. The pressure plate 455 abuts against the synchronous belt 454 to restrict its outward expansion, and by keeping the synchronous belt 454 in continuous contact, tight, or meshed with the synchronous wheel 452 and driven wheel 453, the effectiveness of power transmission in the transmission section is enhanced, and the synchronous belt 454 is less likely to come off or slip during transmission. In some embodiments, the thickness of the pressure plate 455 may be appropriately increased, or a movable or detachable structure may be provided, so that the tension of the synchronous belt 454 can be adjusted when the pressure plate 455 abuts against the synchronous belt 454.

[0032] As shown in Figures 5 and 6, the scraping device is used to perform a scraping operation on the surface of the conveyor belt 3. Multiple scraping devices are provided. The multiple scraping devices are arranged evenly in the conveying direction B to realize multiple scraping operations on the conveyor belt 3. In the conveying direction B, the scraping devices and the washing rollers 44 are arranged adjacent to each other and alternately (staggered) with gaps in between to realize alternating washing and scraping operations on the conveyor belt 3. Specifically, the scraping device comprises a reciprocating lead screw 431, a limit slide bar 432, and a drive block 433. The reciprocating lead screw 431 has a screw structure and is rotatably mounted on the water collection frame 41. A driven wheel 453 is coaxially attached to the shaft end of the reciprocating lead screw 431. The rotation of the driven wheel 453 rotates the reciprocating lead screw 431. The limit slide bar 432 employs a slide bar structure fixed to the inner wall of the water collection frame 41. Two limit slide bars 432 are provided, positioned adjacent to each other on both sides of the reciprocating lead screw 431. The limit slide bars 432 are used to restrict and guide the drive block 433. The limit slide bars 432 and the drive block 433 are connected through a shaft hole. The drive block 433 employs a block-like structure, and multiple drive blocks 433 are provided, arranged along the axial direction (width direction) of the reciprocating lead screw 431. The drive block 433 is movably positioned on the reciprocating lead screw 431. The drive block 433 is provided with a screw hole, and the drive block 433 is screwed onto the reciprocating lead screw 431 through the screw hole. The drive block 433 is also provided with a through-hole structure that allows it to be slidably fitted onto the limit slide bar 432. In addition, each drive block 433 is provided with a scraper 434. The scraper 434 has a "gate" shaped structure and is used to scrape off foreign matter from the surface of the conveyor belt 3. A scraping surface 435, which may be flat or inclined, is provided on the upper side of the scraper 434. A scraping gap 436 is provided in the scraping surface 435. The scraping gap 436 has a hollow structure and can divide the scraping surface 435 into two surfaces.

[0033] During use, the synchronous belt 454 rotates the driven wheel 453, which in turn rotates the reciprocating lead screw 431, causing the drive block 433 to move along the limit slide bar 432 and the reciprocating lead screw 431. The scraping surface 435 can contact the surface of the conveyor belt 3. The drive of the drive block 433 causes the scraper 434 to perform a scraping motion against the conveyor belt 3. Foreign matter on the conveyor belt 3 peels off through the scraping gap 436 and is less likely to repeatedly adhere to the scraper 434. The reciprocating movement of multiple scrapers 434 along the conveyor belt 3 effectively scrapes off foreign matter from the surface of the conveyor belt 3, helping to improve cleanliness.

[0034] Furthermore, as shown in Figure 4, the water collection frame 41 is equipped with exhaust fans 413 for driving hot air. Multiple exhaust fans 413 are provided, arranged along the width direction, and positioned closer to the right edge of the water collection frame 41. That is, in the conveying direction B, the exhaust fans 413 are positioned downstream of the washing rollers 44. Therefore, after the washing and scraping operations by the washing rollers 44 and scraping device, the conveyor belt 3 is dried by the exhaust fans 413. Preferably, the exhaust fans 413 can blow hot air toward the conveyor belt 3. The exhaust fans 413 may be hot air fans or driven fans with heaters. Since the airflow direction driven by the exhaust fans 413 is toward the conveyor belt 3, the conveyor belt 3 is quickly dried as it passes over it, ensuring a degree of dryness before conveying the conveyor belt 3, and helping to maintain the cleanliness of the conveyor belt 3.

[0035] Operating principle: Taking one cycle of the conveyor belt 3 as an example, the transfer roller 2 is activated and driven to transport the material onto the conveyor belt 3. The upper side (recess 31) of the conveyor belt 3 can transport the material (e.g., sake lees) along the transport direction A. The lower side of the conveyor belt 3 is the return circulation section, which is cleaned and scraped by the cleaning mechanism 4. In the transport direction B, the conveyor belt 3 first passes through the first flusher 421 and the second flusher 422 in sequence. Under the pressure of the pressurizing pump, the first flusher 421 sprays detergent onto the conveyor belt 3, and the second flusher 422 cleans the conveyor belt 3. When the drive unit 451 is activated, the cleaning roller 44 is rotated. The cleaning roller 44 rotates the reciprocating lead screw 431 through the cooperation of the synchronous belt 454 and the driven wheel 453, moving the scraper 434. The conveyor belt 3 is subjected to multiple alternating washing and scraping operations simultaneously by the washing roller 44 and scraper 434, removing foreign matter from the surface of the conveyor belt 3 and collecting it in the water collection frame 41. Finally, the conveyor belt 3 is dried by the action of the exhaust fan 413, and the conveyor belt 3 moves on to the next cycle.
