Description

Technical Field

[0001] The present invention belongs to the technical field of watermelon loading, and particularly relates to a watermelon loading device and method. Background Art

[0002] Watermelons have become one of the main summer heat-relieving fruits for people. After the watermelons are ripe in the plantation, they need to be picked, transported, and shipped to all parts of the country. Therefore, they need to be loaded and transported. Usually, watermelons are loaded into the carriage of a transport vehicle for transportation. During the current loading process, people use a conveyor belt to transport the picked watermelons into the carriage. The specific method is as follows: First, the vehicle is parked steadily, and the conveyor belt is moved to one side of the carriage. Then, the conveyor belt is adjusted so that the end close to the carriage is tilted upward until it is higher than the height of the carriage. Then, the picked watermelons are placed in turn at the other end of the conveyor belt, and the conveyor belt is used to transport the watermelons into the carriage. When the watermelons are transported to the end of the conveyor belt close to the carriage, they need to be manually removed and stacked in the carriage. During this process, as the watermelons are continuously stacked, the overall stacking height will increase with the number of watermelons. In order to improve the stacking stability, the current stacking method is in the form of a trapezoid from bottom to top. However, there is still a problem that the lower watermelons are under excessive stress and slide, resulting in collapse as the height increases. Moreover, as the stacking progresses, the bottom of the carriage will be covered with watermelons. When subsequent watermelons are stacked, the people stacking the watermelons will stand on the watermelons, which not only poses a risk of trampling on the watermelons and causing breakage and damage, but also there is a safety problem that the feet of the people stacking the watermelons may slip into the gaps between the watermelons and cause sprained ankles due to the smooth surface of the watermelons. Summary of the Invention

[0012] Preferably, a method for using the above-mentioned watermelon loading device is characterized in that the method includes the following steps: S1: Place the storage box across the moving track, and the supporting wheels arranged on both sides thereof are located on both sides of the moving track. Move the transfer assembly along the moving track so that the transfer assembly is located below the barrel wall, and use the lifting member to drive the column to push the supporting assembly to a position near the upper opening of the barrel wall, so that there is a safe distance between the supporting assembly and the discharging end of the conveyor belt; S2: Use the conveyor belt to convey watermelons onto the supporting assembly in the storage box so that the first layer of watermelons is fully covered on the supporting assembly; S3: Drive the column to descend by the lifting member so that the supporting assembly descends a preset height in the barrel wall to facilitate laying the second layer of watermelons on the basis of the first layer of watermelons; S4: Repeat the operations of S2 - S3 until the supporting assembly descends to the limiting frame at the bottom of the barrel wall and the inside of the storage part is fully filled with watermelons; S5: Drive the column to descend and leave the supporting component through the lifting component until the transfer component is in the initial state; as the column descends, the first friction strip drives the friction wheel to rotate, causing the second friction strip to drive the vertical plate to rise and be located on one side of the cylinder wall; S6: Use the walking trolley to move along the moving track, and push one side of the cylinder wall through the vertical plate until the storage box filled with watermelons is moved to the preset position.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] Please refer to Figures 1 to 7 , in a specific embodiment of the present application, a watermelon loading device includes: A loading platform 2; At least one transfer component 1, the transfer component 1 is movably disposed on the loading platform 2; A plurality of storage boxes 3, the transfer component 1 can move the storage boxes 3 to a preset position on the loading platform 2 so as to arrange a plurality of the storage boxes 3 on the loading platform 2; Wherein: the transfer component 1 is an automatic handling device capable of automatically transferring objects, which can be an AGV unmanned automatic guided vehicle or an automatic handling robot, and can realize moving the storage box 3 filled with watermelons to a preset position on the loading platform 2; The loading platform 2 is a carrier for placing a plurality of storage boxes 3, which can be a freight car carriage or any device for transporting goods; The storage box 3 is a facility for loading watermelons, which can be a plastic box, a plastic bucket, or a metal box, a metal bucket, as long as it can realize the loading of watermelons; In the above solution, the storage box 3 is placed on the loading platform 2, and then watermelons are loaded into the storage box 3. After the storage box 3 is filled, the transfer component 1 on the loading platform 2 drives the storage box 3 filled with watermelons to move to a preset position on the loading platform 2 (the position where the storage boxes 3 are arranged in sequence), and then the transfer component 1 resets to return to the initial position (the position where the transfer component 1 was initially parked on the loading platform 2). Then, the above process is repeated. The second storage box 3 is placed on the loading platform 2 and the loading of watermelons is completed. After loading, the second storage box 3 is moved next to the first storage box 3. The above process is repeated to achieve the sequential loading and arranged placement of several storage boxes 3; Through the above process, the modular loading of watermelons can be achieved. The watermelons are packaged separately in several independent storage boxes 3, and the space in the carriage (loading platform 2) can be divided into several small spaces. After each small space is filled separately and then arranged to fill the carriage, the watermelons can be loaded in each small space and restricted, avoiding the collapse of watermelons during the loading process in the carriage. During the loading process of each storage box 3, there will be no watermelons in other spaces of the carriage, avoiding the trampling and damage of watermelons by personnel during the traditional overall laying and loading of watermelons, and also avoiding the situation where personnel sprain their feet because the surface of the watermelon is smooth and their feet slip into the gaps between watermelons; At the same time, after several storage boxes 3 are filled with watermelons, the effect of neatly arranging several storage boxes 3 in the carriage can be achieved.

[0020] In the above text, the method of loading watermelons can be to move the conveyor belt to one side of the carriage, adjust the conveyor belt so that the end close to the carriage is tilted upward until it is higher than the height of the carriage, and then place the picked watermelons on the other end of the conveyor belt in sequence. When the watermelons are transported to the end of the conveyor belt close to the carriage, the watermelons are manually removed and placed into the storage box 3. However, this requires the operator to continuously place the watermelons into the storage box 3 after removing them. During this process, the operator needs to repeatedly operate to place the watermelons in the storage box 3, which is time-consuming and laborious, and even requires multiple operators to operate. Therefore, a supporting component 303 that can move in the height direction of the storage box 3 is provided in the storage box 3; among them, the supporting component 303 can be a flat plate that can move up and down in the vertical direction, or a rack that can move up and down in the vertical direction; When loading watermelons, the supporting assembly 303 is located inside the containing box 3, and then the operator uses an external tool to control the height of the supporting assembly 303 inside the containing box 3. First, the supporting assembly 303 is raised, and the distance from the upper open end of the containing box 3 is appropriate, so that the watermelons will not be broken when they fall from the end (unloading end) of the conveyor belt 4 close to the carriage to the supporting assembly 303. Specifically, the supporting assembly 303 can be raised to a position with a safe distance (which can be 10 cm, 15 cm) from the unloading end of the conveyor belt 4, so that the watermelons can fall directly on the supporting assembly 303 in the containing box 3 when they are transported up by the conveyor belt 4. There is no need to manually pick and place them one by one. The operator only needs to move the watermelons on the supporting assembly 303 to make them evenly distributed, and spread a layer of watermelons on the supporting assembly 303. After the watermelons are placed on the first layer, the supporting assembly 303 is controlled to descend to a suitable height (a preset height of 10 cm or 15 cm) so that the distance from the subsequent falling watermelons to the first layer of watermelons is controlled within a safe range (that is, the distance from the subsequent falling watermelons to the first layer of watermelons is within a safe distance). In the above process, the watermelons can be loaded layer by layer into the holding box 3 only by controlling the lifting and lowering of the supporting assembly 303. The watermelons can be evenly placed on the supporting assembly 303 by simply moving it, so that the watermelons are loaded layer by layer, and the supporting assembly 303 is controlled to gradually descend until the watermelons fill the holding box 3. The above process can be completed by only one person, avoiding the need for multiple operators to take the watermelons off and continuously place them in the holding box 3, thus solving the problem of time-consuming and labor-intensive operations, and even requiring multiple operators to operate.

[0021] The support assembly 303 may be a suspension structure that moves from top to bottom, or a support structure that moves from top to bottom. However, the suspension structure may interfere with the operation above the storage box 3, while the support structure will not interfere with the process of loading the watermelons into the storage box 3 from top to bottom. Therefore, the transfer component 1 is provided with a lifting module for driving the supporting component 303 to move up and down in the containing box 3; the lifting module is a device that can lift the supporting component 303 up and down in the containing box 3 by pushing the supporting component 303 from below, which can be an oil cylinder or an air cylinder, or an electric telescopic rod; the transfer component 1 can drive the lifting module to move to the bottom of the containing box 3, use the lifting module to enter the containing box 3 to contact the supporting component 303 and lift the supporting component 303 upward, so that the supporting component 303 rises in the containing box 3, and reduces the distance between the supporting component 303 and the upper open end of the containing box 3; Through the above-mentioned method, the power source of the supporting component 303 can be set below the supporting component 303, and there are no facilities in the space above the supporting component 303, which will not interfere with and affect the loading of the watermelon.

[0022] In an alternative embodiment, the jacking module includes a lifting member 103 and a column 104 fixed to the lifting member 103. The column 104 can contact the bottom of the supporting assembly 303. The lifting member 103 can be an oil cylinder or a pneumatic cylinder, or can also be an electric telescopic rod. When the jacking module needs to lift the supporting assembly 303, the lifting member 103 gradually extends, driving the column 104 to rise and gradually contact the bottom of the supporting assembly 303. After contact, the supporting assembly 303 is driven to be lifted. It should be noted that when the jacking module does not need to lift the supporting assembly 303, the upper end of the column 104 is lower than the storage box 3, so that the transfer assembly 1 can smoothly enter and exit the bottom of the storage box 3.

[0023] After the first storage box 3 is filled with watermelons, it is necessary to move the storage box 3. On the one hand, it is to move the storage box 3 to a preset position on the loading platform 2 for neat arrangement. On the other hand, because of the form of the conveyor belt 4 for transporting watermelons mentioned above, the conveyor belt 4 is large in volume and not easy to move. Therefore, to avoid the physical effort of moving back and forth to load the watermelons into the second storage box 3 after removing the watermelons from the conveyor belt 4 by personnel. Preferably, a box-pushing part is provided on the transfer assembly 1 for driving the storage box 3 to move on the loading platform 2. The box-pushing part is a device that can push the storage box 3 filled with watermelons to make the storage box 3 move on the loading platform 2. One way can be that the output end of an oil cylinder, a pneumatic cylinder or an electric telescopic rod contacts the outer wall of the storage box 3, and the storage box 3 is pushed to a predetermined position on the loading platform 2 through the push of the output end. In this way, support wheels are provided at the bottom of the storage box 3. Another way is that the box-pushing part is a device that can hold or clamp the storage box 3, so as to drive the storage box 3 to move and place through the movement of the transfer assembly 1.

[0024] Please refer to Figures 1 to 7 , in an embodiment of the present application, the transfer assembly has a walking base. The box-pushing part includes a vertical frame 102 provided on the walking base and a vertical plate 107 sliding on one side of the vertical frame 102. The lifting member 103 is fixed on the walking base, and the column 104 slides on the vertical frame 102. A friction wheel 106 is rotatably connected to the lower end of the middle part of the vertical frame 102. First friction strips 105 are respectively fixed to the column 104 and the inner side of the vertical plate 107. The vertical plate 107 slides on the vertical frame 102, and a second friction strip 108 and a second friction strip 108 are fixed to the inner side of the vertical plate 107. The first friction strip 105 and the second friction strip 108 are respectively located on both sides of the friction wheel 106 and are in friction transmission with the friction wheel 106. After the vertical plate 107 rises, it can contact the outer wall of the barrel wall 301. The lifting member 103 can be an oil cylinder, a pneumatic cylinder or an electric telescopic rod, or can also be a scissor lift. When loading watermelons, the transfer assembly 1 is in the initial position, the vertical frame 102 is located below the barrel wall 301, the vertical plate 107 is located on the lower side of the vertical frame 102, the inner side of the upper end of the second friction strip 108 is in contact with the friction wheel 106, and the lowest end of the first friction strip 105 inside the column 104 is not in contact with the friction wheel 106. Then, the lifting member 103 drives the column 104 to rise, so that the column 104 contacts the lower part of the supporting assembly 303 from below and jacks up the supporting assembly 303, causing the supporting assembly 303 to move upward inside the storage box 3, realizing a reduction in the distance between the upper surface of the supporting assembly 303 and the upper open end of the storage box 3, and reducing the distance between the watermelons from the conveyor belt 4 or the hands of the personnel and the supporting assembly 303; as the watermelons are loaded, the lifting member 103 drives the column 104 to gradually descend. After the storage box 3 is filled with watermelons, the lower end of the supporting assembly 303 contacts the bottom of the storage box 3, and the column 104 continues to descend and no longer contacts the supporting assembly 303. As the column 104 descends, the first friction strip 105 will contact the friction wheel 106 for friction drive, causing the friction wheel 106 to rotate. Using the friction between the friction wheel 106 and the second friction strip 108, the second friction strip 108 drives the vertical plate 107 to rise. When the column 104 descends to the lowest end, the upper end of the first friction strip 105 remains in contact with the friction wheel 106, and the lower end of the second friction strip 108 remains in contact with the friction wheel 106. At this time, the vertical plate 107 rises to the highest state, and the vertical plate 107 is located on the side of the storage box 3. Subsequently, through the movement of the transfer assembly 1, the vertical plate 107 contacts the side of the storage box 3 and pushes the storage box 3, causing the storage box 3 to move in the moving direction of the transfer assembly 1. After the storage box 3 moves to the preset position, the column 104 is raised to reset, which can cause the first friction strip 105 to rise and drive the friction wheel 106 to rotate in the reverse direction, causing the friction wheel 106 to drive the second friction strip 108 and the vertical plate 107 to descend and reset. After resetting, the heights of the vertical plate 107 and the column 104 are both lower than the bottom end of the storage box 3, without interference, so as to facilitate the transfer assembly 1 to move away from below the storage box 3; Through the above process, the lifting and lowering of the column 104 can be used to realize the lifting and lowering movement of the supporting assembly 303 in the storage box 3. When rising, the distance between the watermelon and the supporting assembly 303 is reduced, and the height of the watermelon falling onto the supporting assembly 303 is reduced, thereby reducing the force between the watermelon and the supporting assembly 303 after the watermelon falls and avoiding the watermelon from being damaged; it can also be achieved in such a way that the supporting assembly 303 gradually descends, so as to ensure that after the watermelon on the conveyor belt 4 falls, the distance between the supporting assembly 303 for receiving the watermelon and the watermelon on the uppermost layer of the supporting assembly 303 reaches a safe range, and the damage rate during the loading process can be reduced; At the same time, after the loading of watermelons is completed, several storage boxes 3 are moved in sequence to arrange several storage boxes 3 in the carriage (loading platform 2).

[0025] In addition, through the lifting process of the column 104 to drive the corresponding lifting of the vertical plate 107, the form of the power source to be set can be reduced during this process (using an oil cylinder or a cylinder to drive the lifting of the vertical plate 107). This can not only reduce the overall weight of the transfer assembly 1, but also reduce the manufacturing cost and use cost of the transfer assembly 1. It can reduce the operation steps and workload through a cooperative form (using an independent oil cylinder or cylinder to drive the lifting of the vertical plate 107); the first friction strip 105 and the second friction strip 108 in the above text can also be replaced by racks, and at this time, the friction wheel 106 needs to be replaced by a gear.

[0026] During the use process, since the transfer assembly 1 needs to move under the storage box 3 and the column 104 is used to support the supporting assembly 303, as the watermelons are loaded, the force borne by the column 104 will be applied to the transfer assembly 1. In this case, the pressure received by the transfer assembly 1 increases, and it is necessary to improve the stability of the transfer assembly 1 to avoid problems such as shaking or slipping of the transfer assembly 1. Therefore, the walking base includes a walking trolley 101 and four cylinders 109 arranged at the four corners of the walking trolley 101, and the cylinders 109 face downward. A support block 110 is fixed on the cylinder rod of each cylinder 109. The walking trolley 101 is a device that can move on a plane. It can be a device remotely controlled by an operator or a device that moves automatically after programming. In the initial state, the cylinder rods of the four cylinders 109 retract, and the bottom surface of the support block 110 does not contact the loading platform 2. After the transfer assembly 1 moves under the storage box 3, the cylinder rods of the four cylinders 109 at the four corners extend, and the cylinder rods drive the support block 110 to descend and contact the loading platform 2, so as to complete the connection and support between the four corners of the walking trolley 101 and the loading platform 2. Through the above process, the range formed by the fulcrums where the walking trolley 101 contacts the loading platform 2 can be increased during the use process, thereby improving the stability of the walking trolley 101 and avoiding problems such as shaking or slipping of the walking trolley 101 when it is under greater pressure.

[0027] In addition, a number of storage boxes 3 filled with watermelons need to be arranged in sequence. Therefore, when the walking trolley 101 pushes the storage box 3 to move, the accuracy of its route needs to be improved to ensure that the movement trajectories of each box are the same, so as to realize the neat arrangement of a number of storage boxes 3. Therefore, a moving track 201 is provided on the loading platform 2 for the transfer assembly 1 to move along the moving track 201. In this way, the moving track 201 can be a slide rail or a runway, or a frame made of wood. Its function is to restrict the walking trolley 101 so that the walking trolley 101 can move according to the movable area formed by the slide rail, runway or wood frame. By controlling the moving track of the walking trolley 101, the accuracy of the route of each movement of the walking trolley 101 can be achieved, and the route of the walking trolley 101 pushing the storage box 3 can be kept stable, so as to achieve the effect of neatly arranging a number of storage boxes 3.

[0028] As described above, a supporting assembly 303 capable of moving in the height direction of the storage box 3 is provided in the storage box 3. Specifically, the storage box 3 includes a cylindrical wall 301 and a limiting frame 302 formed at the lower end of the cylindrical wall 301, and the supporting assembly 303 can be erected on the limiting frame 302. The supporting assembly 303 is placed on the limiting frame 302 to block the lower end of the cylindrical wall 301, and after the watermelon is full, the supporting assembly 303 stably holds the watermelon. In the above text, after the transfer assembly 1 finishes pushing and arranging the storage boxes 3, the transfer assembly 1 needs to move out from under the arranged storage boxes 3 so that the transfer assembly 1 can return to the predetermined position (the position of the transfer assembly 1 when the first storage box 3 is loaded with watermelon, the initial position mentioned above) to support and load another storage box 3 with watermelon and move after loading. Therefore, there should be no interference between the transfer assembly 1 and the lower end of the storage box 3 to avoid preventing the transfer assembly 1 from moving away. Therefore, support wheels are provided on the corresponding two sides at the lower end of the cylindrical wall 301, and the height of the transfer assembly 1 in its initial state (the columns 104 and the vertical plates 107 of the transfer assembly 1 are both lower than the bottom end of the cylindrical wall 301) is lower than the bottom end of the cylindrical wall 301. With the support of the support wheels, the support wheels can straddle above the transfer assembly 1, and the gap between the two support wheels on both sides is the space reserved for the movement of the transfer assembly 1. The transfer assembly 1 can smoothly move under the cylindrical wall 301, and then the lifting module moves upward through the limiting frame 302 to lift the supporting assembly 303 to adjust the distance from the end of the conveyor belt 4. After the watermelon is loaded, the transfer assembly 1 can move the lifting module back to its original position and leave the lower end of the cylindrical wall 301, and then push the storage box 3 through the box-pushing part for placement. After the placement is completed, it moves away from under the cylindrical wall 301. In the above process, it can fully meet the requirement that after the transfer assembly 1 moves under the cylindrical wall 301, the supporting assembly 303 is supported and lifted upward, and is separated after the watermelon is full. After the storage box 3 is placed, interference is avoided to prevent the transfer assembly 1 from moving out smoothly.

[0029] In this embodiment, the specific method for loading watermelons is as follows: S1: After the transport vehicle is parked stably, then the mobile track 201 is erected in the carriage. The first storage box 3 is spanned across the mobile track 201, and the output end of the conveyor belt 4 is moved above the first storage box 3, and the support wheels provided on both sides thereof are located on both sides of the mobile track 201. The transfer assembly is moved along the mobile track 201 so that the transfer assembly 1 is located below the barrel wall 301, and the lifting member 103 is used to drive the column 104 to push the supporting assembly 303 to a position near the upper opening of the barrel wall 301, so that there is a safety distance between the supporting assembly 303 and the discharging end of the conveyor belt 4; S2: Start the conveyor belt 4, and sequentially place the picked watermelons on the conveyor belt 4.
