Description

Technical Field

[0001] The invention relates to a linen washing equipment structure, in particular to an equipment group and method for automatic feeding and discharging of a top-opening industrial washing machine. Background Art

[0002] Industrial washing equipment is widely used in the field of linen washing, especially industrial washing and dehydrating machines as the core equipment of linen washing, which undertake key links such as washing and dehydration. However, there are many shortcomings in the existing industrial washing and dehydrating machines and their related supporting equipment, which seriously restrict the industry efficiency and the safety of workers' operation. The specific problems are as follows: 1. Loading process problems Currently, the loading of linens is mainly done manually, and the entire operation process is time-consuming and labor-intensive. Due to the large capacity of industrial washing and drying machines, loading linens takes a long time, and workers need to repeat high-intensity movements many times, resulting in huge physical energy consumption, which directly affects their health. In addition, due to the high job requirements, it is difficult for companies to recruit workers, which further increases the difficulty of production; 2. Problems with uninstallation During the unloading process after washing, the moisture content of the linens is high (about 50%), resulting in a large weight. Workers need to expend a lot of physical strength to complete the unloading operation. In addition, the machine needs to rotate intermittently during unloading, and the linens are easily twisted into balls. If the operation is improper or the safety protection is insufficient, the workers may be injured by the rotating machine parts, which poses a high safety risk. 3. Linen entanglement and clumping problems When unloading an industrial washing and drying machine, due to the entanglement between linens, especially large linens such as bed sheets and quilt covers, it is often difficult to separate the linens. Such clumped linens are difficult to fully unfold during the subsequent drying process, resulting in uneven drying and a large amount of heat energy consumption, which increases energy consumption. In addition, in order to meet the ironing requirements, the linens need to be pulled and separated manually, which is time-consuming and labor-intensive, and difficult to improve work efficiency. 4. Problems with the existing feeding structure Currently, most of the isolated industrial washing and drying machines on the market adopt a top feeding structure. This design requires a large platform to be built above the equipment. Workers put the linens through the platform and use a long stick to poke and send them. This operation method is high in risk, cost, and time, which is not conducive to improving the production efficiency and safety of the enterprise.

[0003] In order to solve the above technical problems, although structures that can realize automatic loading of linens have been produced in the market, such as the patent of an isolated washing machine with AGV that automatically loads linens (Announcement No. CN214496781U), this type of loading cannot achieve separate loading of linens according to their classification, and the traditional loading method is that it is difficult to reach the loading capacity even if the dry linens are squeezed hard. The method of flushing the linens with water often blocks the mouth to form a pagoda shape due to the floating of the linens, and still needs to be pushed in with the help of external force. Summary of the invention

[0004] To solve the above technical problems, the purpose of the present invention is to provide an equipment group and method for automatic loading and unloading of top-loading industrial washing machines, aiming to optimize the loading and unloading processes, improve the efficiency of linen washing, reduce the labor intensity of workers, and reduce safety accidents.

[0005] The present invention provides the following technical solutions: A device group for automatic feeding and discharging of an upper-door industrial washing machine, comprising an upper-feeding industrial washing machine, a mother-and-child feeding bucket that moves to the feeding port of the upper-feeding industrial washing machine to load linens, and an anti-skid conveyor belt climbing machine connected to the discharging port of the upper-feeding industrial washing machine, wherein the mother-and-child feeding bucket comprises an outer cylinder, a through hole is opened in the middle of the groove bottom of the outer cylinder, a middle barrel with a door opening mechanism at the bottom and raised and lowered through the through hole is built into the outer cylinder, a bottomless left barrel and a bottomless right barrel are also arranged on both sides of the middle barrel in the outer cylinder, and the middle barrel is lowered to the same level as the outer cylinder. When the feed port is docked and the bottomless left barrel or the bottomless right barrel slides above the middle barrel, the linens in the bottomless left barrel or the bottomless right barrel fall into the middle barrel through the bottom that is connected to the top of the middle barrel. A nozzle is also arranged above the middle barrel, and the nozzle is used to spray water into the middle barrel until the linens are completely soaked and wet, then the door opening mechanism at the bottom of the middle barrel is opened, so that the mixture of linens and water falls into the drum of the top-feed industrial washing machine under the action of gravity. The bottom feeding end of the anti-slip conveyor belt climbing machine is docked below the discharge port, and the top feeding end thereof is supported above the linen frame; At this time, after the linens are fully soaked with water, the volume of the linens will shrink to the minimum, the total weight of the water-containing linens will reach the maximum, the falling force will also be the largest, and the fluidity will be the smoothest. Therefore, the linens remaining in the bottomless left barrel or the bottomless right barrel can all enter the middle barrel smoothly. When the door opening mechanism of the middle barrel opens the door, the linens can easily enter the limited space of the washing machine drum, which can avoid the linens from clogging the mouth and avoiding linens from remaining.

[0006] Preferably, the door opening mechanism includes an outer frame for supporting the middle barrel, double doors hingedly installed on both sides of the bottom of the middle barrel, and a driving cylinder hingedly installed on the outer frame for driving the upper door to open or close. The two door leaves of the double door are closed and distributed in a V shape, and a drainage outlet is also provided on the door leaf. Therefore, when water is sprayed on the linens, the water above will soak the linens from top to bottom in sequence. After the linens are completely soaked, the excess water will be discharged from the drainage outlet, and the linens at the bottom are also arranged in the V shape of the double door. After the double door is driven to open, the linens can fall from the opening into the drum of the washing machine more smoothly, which can better avoid the linens from clogging the opening and also avoid linen residue.

[0007] Preferably, two groups of cylinders 1 for driving the middle barrel to rise and fall are arranged on the side walls on the front and rear sides of the outer cylinder body, and two groups of cylinders 2 for respectively pushing the bottomless left barrel and the bottomless right barrel to the top of the middle barrel are also arranged on the side walls on the left and right sides of the outer cylinder body. The degree of automation of the driving can be further improved by driving cylinders 1 and 2.

[0008] Preferably, the outer cylinder is placed on a bottom frame, driving brackets are provided on both sides of the bottom frame, the driving brackets are placed on a lifting frame through rollers, the lifting frame is raised and lowered in a horizontal moving frame driven by a top lifting machine, and two sets of upper guide rails are provided on the top of each group of top-feed industrial washing machines, when the upper guide rails are aligned with the driving brackets of the lifting frame, the outer cylinder is dragged by the bottom frame to slide out of the lifting frame and placed on the upper guide rails, at which point the rollers of the driving brackets can move up to the upper guide rails to form a rolling support that drives the bottom frame and the outer cylinder up to the upper guide rails, at which time the outer cylinder can be manually pushed to roll on the upper guide rails until it moves above the feed port, and the middle barrel then descends to dock with the feed port, or the rollers can be driven to rotate by an automated servo motor so that the rollers can automatically move on the upper guide rails to improve the degree of automation.

[0009] Preferably, the top-feed industrial washing machines are provided with a plurality of groups arranged side by side, and a group of track chassis is also provided along the arrangement direction of the top-feed industrial washing machines, and the horizontal movable frame is slidably installed on the track chassis. Therefore, by driving a group of horizontal movable frames to and fro between the plurality of groups of top-feed industrial washing machines, a group of horizontal movable frames can be adapted to the loading conditions of the plurality of groups of top-feed industrial washing machines, thereby improving the utilization rate of the equipment.

[0010] Preferably, the conveyor belt of the anti-skid conveyor belt climber is also provided with a plurality of groups of spaced-apart partitions, which are distributed side by side along the conveying direction of the conveyor belt, and limit baffles are also provided at the bottom input end of the conveyor belt and on both sides of the conveyor belt. Thus, the anti-skid conveyor belt climber can form a conveyor belt with limit baffles on three sides to prevent the linens from slipping off the conveyor belt to the bottom when being discharged onto the conveyor belt. At the same time, the partitions can further play a blocking effect to improve the efficiency of positioning the linens on the conveyor belt and transporting them to the linen frame with the conveyor belt. When the linens are discharged from the discharge port, after the discharge door of the washing machine is opened, the drum will still rotate left and right to discharge. During the rotating discharging process, the linens discharged from the discharge port can automatically fall to the bottom input end of the conveyor belt, which can prevent the discharged linens from accumulating at the discharge port on the conveyor belt, and also prevent large linens from being entangled with each other.

[0011] A method for automatically loading and unloading materials in a top-loading industrial washing machine, based on the above-mentioned equipment group for automatically loading and unloading materials in a top-loading industrial washing machine, is characterized by comprising the following steps: S1: Put the linens into the mother-and-child feeding bucket; S2: lift the mother-child feeding bucket and move it to the feeding position above the feeding port; S3: Drive the middle barrel down so that its port is slightly lower than the bottom surface of the outer barrel with the driving mechanism, and then the nozzle corresponding to the position of the middle barrel above the feeding position starts to spray water into the middle barrel until the linens are completely soaked and wet. Then the door opening mechanism of the middle barrel opens, and the mixture of linens and water falls into the drum of the washing machine under the action of gravity. After the linens are fully soaked by water, the volume of the linens will shrink to the minimum, the total weight of the water-containing linens will reach the maximum, the falling force will also be the largest, and the fluidity will be the smoothest, making it very easy for the linens to enter the limited space of the washing machine drum. In the traditional loading method, dry linens are squeezed hard and it is difficult to reach the loading capacity. The method of flushing the linens with water also blocks the mouth to form a pagoda shape due to the floating of the linens, and needs to be poked in with the help of external force; S4: the door opening mechanism of the middle barrel is closed, and the bottomless left barrel is driven to dock with the top of the middle barrel, so that the linens are put into the middle barrel, and then the nozzle starts to spray water to the middle barrel until the linens are soaked, and the door opening mechanism of the middle barrel is opened, so that the linens fall into the drum for the second time, and then the door opening mechanism of the middle barrel is closed, and the bottomless left barrel after the linens fall into the drum for the second time returns to the original position of the bottomless left barrel in S1, and then the bottomless right barrel is driven to dock with the top of the middle barrel, so that the linens are put into the middle barrel, and the nozzle starts to spray water to the middle barrel again until the linens are soaked, and the door opening mechanism of the middle barrel is opened, so that the linens fall into the drum for the third time, and then the door opening mechanism of the middle barrel is closed, and the bottomless right barrel after the linens fall into the drum for the third time also returns to the original position of the bottomless right barrel in S1; S5: Drive the middle barrel upward and return it to the initial position of the middle barrel in S1, and then drive the mother feeding barrel to return to the initial position of S1 along the original route to perform another linen packaging operation, waiting for a new round of linen feeding cycle S2-S4 to be repeated. After each washing, the side door of the top-opening industrial washing machine is opened, and the linens inside the washing machine fall to the bottom feeding end of the anti-slip conveyor belt climbing machine one after another, and under the timely traction of the anti-slip conveyor belt, the received linens are gradually lifted to the upper part of the linen frame and fall into the linen frame, avoiding the entanglement and knotting of the linens, which makes it difficult to sort them out later.

[0012] The beneficial effects of the present invention are: The present invention provides an equipment group and method for automatic loading and unloading of top-loading industrial washing machines, which aims to optimize the loading and unloading process, improve the efficiency of linen washing, reduce the labor intensity of workers, and reduce safety accidents. The key innovations include: 1. Mother-child feeding bucket structure The innovative design of the mother-child feeding bucket simplifies the linen loading process, reduces manual operation time, and improves feeding efficiency; 2. Pre-wetting process Before loading the linens, mix the linens with water by soaking them, and then feed them into the wet state to reduce entanglement problems and optimize the subsequent processing process; 3. Slope-climbing discharging device By introducing a climbing discharging device, the stable discharging of linens is effectively achieved, avoiding entanglement and clumping, while reducing the labor intensity of workers; When multiple sets of top-opening industrial washing machines are working side by side, one side of the horizontal moving frame is connected by a C-type slider and a C-type guide rail. The C-type guide rail is fixed on a square tube horizontal base to form a track chassis. The square tube horizontal base is fixed to the ground with expansion screws. This structure maintains the stability of the bracket and the reliable movement trajectory. Rollers are installed on the other side of the horizontal moving frame in the same direction as the C-type guide rail. The horizontal moving frame can be moved manually or driven back and forth by electric pushing. The lifting frame moves up and down along the track rod on the horizontal moving frame under the traction of the top hoist, and its position is controlled by the electrical induction component, and its principle can be similar to that of the elevator box; The mother-and-child feeding frame includes a bottomless left bucket, a bottomless right bucket, and a liftable middle bucket with a door opening mechanism at the bottom. After the middle bucket is lowered, the bottomless left bucket and the bottomless right bucket can push the linens to the top of the middle bucket in turn. The middle bucket can open and close the lower door when the program control conditions are met; The mother-and-child feeding bucket is driven by its own power system. When the driving bracket of the lifting frame reaches the alignment position of the upper guide rail, the mother-and-child feeding bucket in the lifting frame can run through the upper guide rail to above the feed port above the washing machine, and return to the lifting frame after the feeding is completed.

[0013] After each wash, the anti-slip conveyor belt climbing machine can pull the linens in an orderly manner and lift them above the linen frame, and then drop them into the linen frame under the action of gravity, preventing large linens from being entangled with each other.

[0015] Example 1 like Figure 1-6As shown, an equipment group for automatic feeding and unloading of a top-loading industrial washing machine, in this embodiment, includes a top-feeding industrial washing machine 1, a mother-and-child feeding bucket 2 that moves to the feeding port of the top-feeding industrial washing machine 1 to load linens, and an anti-skid conveyor belt climbing machine 3 that is connected to the discharge port of the top-feeding industrial washing machine 1, the mother-and-child feeding bucket 2 includes an outer cylinder 21, a through hole is opened in the middle of the groove bottom of the outer cylinder 21, the outer cylinder 21 is built with a middle barrel 22 with a door opening mechanism at the bottom and raised and lowered through the through hole, the outer cylinder 21 is also provided with a bottomless left barrel 24 and a bottomless right barrel 23 located on both sides of the middle barrel 22, and the middle barrel 22 When it descends to dock with the feed port and the bottomless left barrel 24 or the bottomless right barrel 23 slides above the middle barrel 22, the linens in the bottomless left barrel 24 or the bottomless right barrel 23 fall into the middle barrel 22 through the bottom that is connected to the top of the middle barrel 22. A nozzle is also arranged above the middle barrel 22, and the nozzle is used to spray water into the middle barrel 22 until the linens are completely soaked and wet. Then, the door opening mechanism at the bottom of the middle barrel 22 is opened, so that the mixture of linens and water falls into the drum of the top-feed industrial washing machine 1 under the action of gravity. The bottom feeding end of the anti-slip conveyor belt climbing machine 3 is docked below the discharge port, and its top feeding end is supported above the linen frame; At this time, after the linens are fully soaked with water, the volume of the linens will shrink to the minimum, the total weight of the water-containing linens will reach the maximum, the falling force will also be the largest, and the fluidity will be the smoothest. Therefore, the linens remaining in the bottomless left barrel 24 or the bottomless right barrel 23 can all enter the middle barrel 22 smoothly, and when the door opening mechanism of the middle barrel 22 opens the door, the linens can easily enter the limited space of the washing machine drum, which can avoid the linens from clogging the mouth and avoiding linens from remaining.

[0016] The door opening mechanism includes an outer frame 221 for supporting the middle barrel 22, a double door 222 hingedly installed on both sides of the bottom of the middle barrel 22, and a driving cylinder 223 hingedly installed on the outer frame 221 for driving the upper door to open or close. The two door leaves of the double door 222 are closed in a V shape, and a drain port 224 is also provided on the door leaf. Therefore, when water is sprayed on the linen, the water above will soak the linen from top to bottom in sequence. After the linen is completely soaked, the excess water will be discharged from the drain port 224, and the linen at the bottom is also arranged in the V shape of the double door 222. After the double door 222 is driven to open, the linen can fall from the opening into the drum of the washing machine more smoothly, which can better avoid the linen from blocking the opening and also avoid linen residue.

[0017] Two groups of cylinders 1 for driving the middle barrel 22 to rise and fall are arranged on the side walls on the front and rear sides of the outer cylinder 21, and two groups of cylinders 2 for respectively pushing the bottomless left barrel 24 and the bottomless right barrel 23 to the top of the middle barrel 22 are arranged on the side walls on the left and right sides of the outer cylinder 21. The degree of automation of the drive can be further improved by driving cylinders 1 and 2 (in order to simplify the drawings, the drive cylinders 223 1 and 223 2 arranged on the outer cylinder 21 are hidden and not shown).

[0018] The outer cylinder 21 is placed on the bottom frame 25, and driving brackets 26 are arranged on both sides of the bottom frame 25. The driving brackets 26 are placed on the lifting frame 5 through rollers 27. The lifting frame 5 is lifted and lowered in the horizontal moving frame 4 under the drive of the top hoist. Two sets of upper guide rails 6 are arranged on the top of each group of upper feeding industrial washing machines 1. When the upper guide rails 6 are aligned with the driving brackets 26 of the lifting frame 5, the outer cylinder 21 is dragged by the bottom frame 25 to slide out of the lifting frame 5 and placed on the upper guide rails 6. At this point, the rollers 27 of the driving brackets 26 can be moved up to the upper guide rails 6 to form a rolling support that drives the bottom frame 25 and the outer cylinder 21 to the upper guide rails 6. At this time, the outer cylinder 21 can be manually pushed to roll on the upper guide rails 6 until it moves above the feed port, and the middle barrel 22 descends to dock with the feed port. The rollers 27 can also be driven to rotate by an automated servo motor so that the rollers 27 can automatically move on the upper guide rails 6 to improve the degree of automation.

[0019] The top-feed industrial washing machines 1 are provided with a plurality of groups arranged side by side, and a group of track base frames are also provided along the arrangement direction of the top-feed industrial washing machines 1, and the horizontal movable frame 4 is slidably installed on the track base frames. Therefore, by driving a group of horizontal movable frames 4 to and fro between the plurality of groups of top-feed industrial washing machines 1, a group of horizontal movable frames 4 can be adapted to the loading conditions of the plurality of groups of top-feed industrial washing machines 1, thereby improving the utilization rate of the equipment.

[0020] The conveyor belt of the anti-skid conveyor belt climber 3 is also provided with a plurality of groups of spaced partitions 31, which are arranged side by side along the conveying direction of the conveyor belt, and limit baffles 32 are also provided at the bottom input end of the conveyor belt and on both sides of the conveyor belt. Thus, the anti-skid conveyor belt climber 3 can form a conveyor belt with limit baffles 32 on three sides to prevent the linens from slipping off the conveyor belt to the bottom when being discharged onto the conveyor belt. At the same time, the partitions 31 can also further play a blocking effect to improve the efficiency of positioning the linens on the conveyor belt and conveying them to the linen frame with the conveyor belt. When the linens are discharged from the discharge port, after the discharge door of the washing machine is opened, the drum will still rotate left and right to discharge. During the rotating discharging process, the linens discharged from the discharge port can automatically fall to the bottom input end of the conveyor belt, so that the discharged linens can be prevented from accumulating at the discharge port on the conveyor belt, and large linens can be prevented from being entangled with each other.

[0021] Example 2 A method for automatically loading and unloading materials for a top-loading industrial washing machine, based on a device group for automatically loading and unloading materials for a top-loading industrial washing machine in Embodiment 1, comprises the following steps: S1: Load the linens into the mother-and-child feeding bucket 2 at the bottom; S2: When the top hoist lifts the mother-and-child feeding bucket 2 until the upper guide rail 6 is aligned with the driving bracket 26 of the lifting frame 5, the outer cylinder 21 is dragged by the bottom frame 25 to slide out of the lifting frame 5 and placed on the upper guide rail 6, and is stationary at the feeding position above the feeding port; S3: driving the middle barrel 22 downward so that its end is slightly lower than the bottom surface of the outer barrel 21 with the driving mechanism, and then the nozzle corresponding to the position of the middle barrel 22 above the feeding position starts to spray water into the middle barrel 22 until the linens are completely soaked and wet. Then the door opening mechanism of the middle barrel 22 opens, and the mixture of linens and water falls into the drum of the washing machine under the action of gravity. After the linens are fully soaked by water, the volume of the linens will shrink to the minimum, the total weight of the water-containing linens will reach the maximum, the falling force will also be the largest, and the fluidity will be the smoothest, making it very easy for the linens to enter the limited space of the washing machine drum. In the traditional loading method, dry linens are squeezed hard and it is difficult to reach the loading capacity. The method of flushing the linens with water also blocks the mouth to form a pagoda shape due to the floating of the linens, and needs to be poked in with the help of external force; S4: the door opening mechanism of the middle barrel 22 is closed, and the bottomless left barrel 24 is driven to dock with the top of the middle barrel 22, so that the linens are put into the middle barrel 22, and then the nozzle starts to spray water to the middle barrel 22 until the linens are soaked, and the door opening mechanism of the middle barrel 22 is opened, so that the linens fall into the drum for the second time, and then the door opening mechanism of the middle barrel 22 is closed, and the bottomless left barrel 24 that completes the second drop of the linens into the drum returns to the initial position of the bottomless left barrel 24 in S1, and then the bottomless right barrel 23 is driven to dock with the top of the middle barrel 22, so that the linens are put into the middle barrel 22, and the nozzle starts to spray water to the middle barrel 22 again until the linens are soaked, and the door opening mechanism of the middle barrel 22 is opened, so that the linens fall into the drum for the third time, and then the door opening mechanism of the middle barrel 22 is closed, and the bottomless right barrel 23 that completes the third drop of the linens into the drum also returns to the initial position of the bottomless right barrel 23 in S1; S5: drive the middle barrel 22 to rise and return it to the original position of the middle barrel 22 in S1, and then drive the mother feeding barrel to return to the original position of S1 along the original route to perform the linen packaging operation again, waiting for a new round of linen feeding cycle S2-S4 to be repeated. After each washing, the side door of the discharge port of the top-opening industrial washing machine is opened, and the linens therein are successively dropped to the bottom feeding end of the anti-slip conveyor belt climbing machine 3, and under the timely traction of the anti-slip conveyor belt, the received linens are successively lifted to the upper part of the linen frame and dropped into the linen frame, thereby avoiding the entanglement and knotting of the linens, which are difficult to sort out later.

[0022] The working principle of the present invention is as follows: the present invention provides an equipment group and method for automatic loading and unloading of top-loading industrial washing machines, which aims to optimize the loading and unloading process, improve the efficiency of linen washing, reduce the labor intensity of workers, and reduce safety accidents. The key innovations include: 1. Mother-child feeding bucket 2 structure The innovative design of the mother-child feeding bucket 2 simplifies the linen loading process, reduces manual operation time, and improves feeding efficiency; 2.

Slope-climbing discharging device By introducing a climbing discharging device, the stable discharging of linens is effectively achieved, avoiding entanglement and clumping, while reducing the labor intensity of workers; When multiple groups of top-opening industrial washing machines are adapted to work side by side, one side of the horizontal moving frame 4 is connected by a C-type slider and a C-type guide rail, and the C-type guide rail is fixed on a square tube horizontal base to form a track chassis, and the square tube horizontal base is fixed to the ground with expansion screws. This structure maintains the stability of the bracket and the reliable movement trajectory. The other side of the horizontal moving frame 4 is equipped with a roller 27 in the same direction as the C-type guide rail. The horizontal moving frame 4 can be moved manually or driven to reciprocate by electric pushing. The lifting frame 5 moves up and down along the track rod on the horizontal moving frame 4 under the traction of the top hoist, and its position is controlled by an electrical induction component, and its principle can be similar to that of an elevator box; The mother-and-child feeding frame includes a bottomless left bucket 24, a bottomless right bucket 23, and a liftable middle bucket 22 with a door opening mechanism at the bottom. After the middle bucket 22 is lowered, the bottomless left bucket 24 and the bottomless right bucket 23 can push the linens to the top of the middle bucket 22 in turn. The middle bucket 22 can open and close the lower door when the program control conditions are met; The mother-and-child feeding bucket 2 is driven by its own power system. When the driving bracket 26 of the lifting frame 5 reaches the aligned position of the upper guide rail 6, the mother-and-child feeding bucket 2 in the lifting frame 5 can move to the upper feeding port of the washing machine through the upper guide rail 6, and return to the lifting frame 5 after the feeding is completed.
