Description

Technical Field

[0001] The present invention relates to the technical field of cargo transportation, and in particular to a water bottle stacking device. Background Art

[0002] Mineral water is one of the products that we use frequently in our daily lives. After the mineral water is bottled, it will be packaged into bags, bundles or boxes. The packaged mineral water bottles are stacked and stored in the cargo compartments of the aisles. When they need to be shipped, the packaged mineral water bottles in the cargo compartments are taken out and transported to the aisle entrance.

[0003] The transportation of mineral water bottles within the aisles is typically accomplished through a stacking device. This device uses a retractable fork to lift the packaged mineral water bottles stacked on pallets. The bottles then shuttle back and forth between the aisles of the warehouse, transporting them. The stacking device primarily consists of a lower crossbeam, loading platform, fork mechanism, columns, upper crossbeam, horizontal operating mechanism, lifting mechanism, electrical control cabinet, safety protection devices, and electrical control system.

[0004] In order to transport more mineral water bottles at one time on a limited pallet area, it is necessary to increase the number of bags, bundles or boxes of mineral water bottles in height. However, the increase in the height of the mineral water bottles will cause the center of gravity to rise, which will easily cause the stacked bags, bundles or boxes of mineral water bottles to fall from the stacking device when the stacking device is running. In particular, the bags or bundles of mineral water bottles are all wrapped in plastic film, which results in less friction between the bags or bundles of mineral water bottles, making them more likely to fall during transportation. In addition, in order to improve transportation efficiency, the speed of the stacking device will be increased as much as possible during operation. However, the increase in the operating speed of the stacking device further causes the goods to fall easily, and safety is lower.

[0005] To improve efficiency and safety, existing technologies often reinforce cargo by adding fixing mechanisms. For example, in the prior art patent application number 202322843124.3 and publication (announcement) number CN221395377U, a downward pressure device is added. The first electric push rod is extended through the connecting seat and the first universal joint to drive the pressure plate and the first buffer pad to move downward and cushion the cargo, thereby improving the firmness of the cargo and preventing it from falling. Another example is the prior art patent application number 202210556666.X and publication (announcement) number 114803951B, which provides multiple sets of fixing components. Each set of fixing components includes multiple telescopic electric cylinders evenly distributed along the circumference of the fork-taking column. A PLC controller controls the piston rods of the telescopic electric cylinders of the multiple sets of fixing components to extend until they abut the inner wall of the coil. The multiple sets of telescopic electric cylinders evenly and stably support and limit the coil, preventing the coil from rolling and falling during handling, thereby effectively improving the efficiency and safety of coil handling and stacking.

[0006] However, the existing technologies all have the same disadvantages: in the existing technologies, the fixing mechanisms for reinforcing the goods are all operated independently by adding independent driving mechanisms. The independent operation of the independent driving mechanisms firstly increases the number of driving mechanisms, thereby increasing the manufacturing cost and maintenance cost of the stacking device; secondly, the independent operation of the fixing mechanisms leads to the problem of smooth connection between the action of reinforcing the goods and its previous action (such as the fork moving the goods to the loading platform of the stacking device). If the connection time is to be reduced and automatic connection is achieved, a more accurate control system auxiliary control is required, but this will undoubtedly further increase the cost of the stacking device and increase the design difficulty of the control system. If the connection is only achieved through manual operation, automatic connection cannot be achieved, which will greatly increase the connection time and the energy consumption of the operator, resulting in low work efficiency. Therefore, how to achieve the smooth connection between the action of reinforcing the goods and the action of moving the goods to the loading platform automatically without manual operation without adding an independent driving mechanism and configuring a separate control system for it, thereby saving costs and reducing the difficulty of control system design while effectively reducing the connection time between the two actions to improve work efficiency is a technical problem that needs to be solved urgently. Summary of the Invention

[0007] The object of the present invention is to provide a water bottle stacking device to solve the above-mentioned deficiencies in the prior art.

[0008] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a water bottle stacking device, comprising a slide rail fixedly mounted on a supporting platform, a fork slidably mounted on the slide rail, and a self-locking drive mechanism mounted on the supporting platform and used to drive the fork to slide back and forth.

[0009] The cargo fork comprises a sliding fork and a supporting fork arranged in an elastic sliding manner, and the self-locking drive mechanism drives the sliding fork to slide back and forth;

[0010] A column is fixedly mounted on the support fork, a pressing member for pressing the packaged water bottle downward is elastically rotatably mounted on the column, and a rope is connected between the pressing member and the sliding fork;

[0011] A limiting plate is fixedly provided on the slide rail and is in contact with the column;

[0012] The self-locking drive mechanism drives the sliding fork to slide to drive the supporting fork and the packaged water bottle to move to the supporting platform. In the process, the upright column and the limit plate abut against each other to cause relative sliding between the sliding fork and the supporting fork. As the sliding fork continues to slide, the rope is driven to pull the pressing piece downward and elastically rotate to squeeze and fix the packaged water bottle.

[0013] In the above-mentioned water bottle stacking device, the pressing member includes a swing plate elastically rotatably arranged with the column, a pressing plate fixedly mounted on the swing plate, and an air bag sealed and fixedly mounted on the bottom of the pressing plate.

[0014] The above-mentioned water bottle stacking device has a slider slidingly provided on the swing plate, a downward rotation limit block is fixedly provided on the slider, a first compression spring is installed between the downward rotation limit block and the column, a fixed plate is fixedly installed on the column, and an abutment plane and an inclined surface are formed on the bottom of the fixed plate. Based on the elastic force of the first compression spring, the top of the downward rotation limit block is located below the abutment plane in the initial state and abuts against the abutment plane so that the downward pressure piece cannot rotate downward.

[0015] The above-mentioned water bottle stacking device has a horizontal plate fixedly installed on the swing plate, and an arc-shaped rod slidably inserted into the horizontal plate is fixedly installed on the fixed plate. A second compression spring is sleeved on the arc-shaped rod, one end of the second compression spring abuts against the fixed plate, and the other end abuts against the horizontal plate. An upper rotation limit block located below the horizontal plate is fixedly installed on the upper part of the arc-shaped rod. In the initial state, the elastic force of the second compression spring pushes the horizontal plate to abut against the upper rotation limit block so that the lower pressure piece cannot rotate upward.

[0016] In the above-mentioned water bottle stacking device, one end of the rope is fixedly connected to the slider and the other end is fixedly connected to the sliding fork. A first directional wheel is rotatably provided on the swing plate, and a second directional wheel is rotatably provided on the sliding fork. The rope abuts and passes around the first directional wheel and the second directional wheel. The elastic force of the first compression spring is smaller than that of the second compression spring. After the column abuts against the limit plate, the continued sliding of the sliding fork first drives the rope to pull the lower rotation limit block to move to the bottom of the inclined surface to release the limit of the lower rotation limit block on the lower pressure piece.

[0017] In the above-mentioned water bottle stacking device, a blocking block is fixedly installed on the swing plate. In the process of the rope pulling the slider to slide, the slider and the blocking block gradually approach and abut against each other to limit the slider. Thereafter, the continued sliding of the sliding fork drives the rope to pull the swing plate and the cross plate to rotate. The rotation of the cross plate squeezes the second compression spring to compress the airbag downward to squeeze the packaged water bottles.

[0018] In the above-mentioned water bottle stacking device, a pier plate is fixedly installed at the end of the support fork, and an abutment plate that abuts and cooperates with the end of the sliding fork is fixedly installed on the pier plate. A tension spring is fixedly connected between the pier plate and the sliding fork, and based on the elastic force of the tension spring, the abutment plate abuts against the sliding fork in the initial state.

[0019] In the above-mentioned water bottle stacking device, based on the elastic force of the tension spring, when the self-locking drive mechanism drives the sliding fork to slide away from the supporting platform, the end face of the sliding fork gradually abuts against the abutment plate to restore the positional relationship between the sliding fork and the supporting fork to the initial state.

[0020] In the above-mentioned water bottle stacking device, a pushing plate is fixedly installed on the sliding fork, and a limiting piece is rotatably provided on the sliding fork, one end of the limiting piece abuts against the bottom of the pushing plate, and the other end is a free end, and an extension plate is fixedly installed on the pier plate to abut against the free end of the limiting piece. During the sliding process of the sliding fork toward the supporting platform, the pushing plate presses down the limiting piece to rotate to drive the free end of the limiting piece to squeeze the extension plate, thereby clamping the supporting fork between the limiting plate and the limiting piece.

[0021] In the above-mentioned water bottle stacking device, the pushing plate includes an integrally arranged seesaw plate and a parallel plate, and the limiting member includes a roller abutting against the bottom surface of the seesaw plate and the bottom surface of the plate. In the process of the pressing member rotating downward to squeeze the packaged water bottles, the roller abuts against the bottom surface of the parallel plate so that the free end of the limiting member squeezes the extension plate.

[0022] Beneficial effects:

[0023] 1. In the above-mentioned technical solution, the present invention provides a water bottle stacking device. By improving the structure of the forks and adding a downward pressure member, the self-locking drive mechanism drives the forks to retract the packaged water bottles onto the support platform. The device cleverly utilizes the relative displacement between the sliding fork and the support fork to automatically apply downward pressure to the packaged water bottles. This downward pressure increases the friction between the multiple packaged water bottles, thereby improving safety during transportation and increasing the conveying speed and efficiency of the packaged water bottles. Because the action of reinforcing the packaged water bottles occurs while the self-locking drive mechanism drives the forks to retract the packaged water bottles onto the support platform, the two actions are seamlessly connected, requiring no operator control, no independent drive for the downward pressure member, and no separate control system. This saves costs and reduces the difficulty of control system design while effectively reducing the connection time between the two actions, thereby improving work efficiency. This effectively addresses the shortcomings of the prior art.

[0024] 2. In the present application, in the process of the fork driving the packaged water bottle to be retracted to the load platform, not only can the connection between the rope and the sliding fork be used to automatically realize the downward pressure of the packaged water bottle by the pressing member, but also the connection between the rope and the slider is cleverly used to automatically realize the unlocking of the pressing member. The unlocking action of the pressing member and the pressing action of the pressing member are also seamlessly connected, eliminating the operation of separately unlocking the pressing member, further improving work efficiency. The unlocking and pressing of the pressing member are both generated by the tension of the rope, so that the rope "kills two birds with one stone", thereby producing unexpected technical effects in the process of the fork retracting the packaged water bottle to the load platform.

[0025] 3. By adding a push plate and a limiter, when the fork drives the packaged water bottle back to the load platform, it drives the push plate to squeeze the limiter to automatically clamp the support fork, so that the support fork will not shake when the packaged water bottle is being transported, further improving the stability of the packaged water bottle.

[0026] 4. The limiter not only limits the position of the support fork during the transportation of the packaged water bottles, but also, based on the contact between the roller and the bottom surface of the parallel plate, keeps the support fork clamped and limited during the process of the relative position between the sliding fork and the support fork returning to the contact state when the packaged water bottles are transported by the fork into the cargo grid, thereby preventing the support fork from shaking.

[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] First embodiment:

[0054] like Figure 1-15 As shown, an embodiment of the present invention provides a water bottle stacking device, comprising a slide rail 2 fixedly mounted on a supporting platform 28, a cargo fork slidably mounted on the slide rail 2, and a self-locking drive mechanism mounted on the supporting platform 28 and used to drive the cargo fork to slide back and forth. The cargo fork includes a sliding fork 1 and a supporting fork 3 that are elastically slidably arranged. The self-locking drive mechanism drives the sliding fork 1 to slide back and forth.

[0055] A column 4 is fixedly mounted on the support fork 3, and a pressing member for pressing the packaged water bottle 43 downward is elastically rotatably mounted on the column 4, and a rope 8 is connected between the pressing member and the sliding fork 1;

[0056] A limit plate 201 is fixedly provided on the slide rail 2 and abuts against the column 4;

[0057] When the self-locking drive mechanism drives the sliding fork 1 to slide to drive the supporting fork 3 and the packaged water bottle 43 to move onto the supporting platform 28, the column 4 abuts against the limiting plate 201 to cause relative sliding between the sliding fork 1 and the supporting fork 3. As the sliding fork 1 continues to slide, the rope 8 pulls the pressing piece downward to rotate elastically to squeeze and fix the packaged water bottle 43.

[0058] The water bottle stacking device provided in this embodiment is used to efficiently and safely transport mineral water bottles packaged in bags, bundles, or boxes in a lane. The terms related to directions and positions in this embodiment are relative to the accompanying drawings. In this embodiment, the downward rotation of the lower pressure member refers to the rotation of the airbag 26 toward the packaged water bottle 43, and the upward rotation of the lower pressure member refers to the rotation of the airbag 26 away from the packaged water bottle 43. Specifically, Figure 1 and 2As shown, it includes a hanging rail 37 and a ground rail 32 arranged opposite to each other in the upper and lower directions. The hanging rail 37 and the ground rail 32 are used for guiding. It also includes two side brackets 33 arranged opposite to each other in the left and right directions. The top ends of the two side brackets 33 are fixedly mounted with a top frame 35. A supporting platform 28 is slidably mounted between the two side brackets 33 through a guiding mechanism. The guiding mechanism includes two pull-out boxes 29 arranged opposite to each other and fixedly mounted on the supporting platform 28. The two pull-out boxes 29 correspond to the two side brackets 33 one-to-one. A first guide rail 3301 and a second guide rail 3302 are fixedly provided on the front and rear sides of each side bracket 33. A first guide groove is formed on the side of the two first guide rails 3301 on each side bracket 33 that are away from each other, and a second guide groove is formed on the side of the two second guide rails 3302 that are facing the pull-out box 29. Two sets of first limiting rollers 2901 and two sets of second limiting rollers 2902 are rotatably mounted on the sides of the two pull-out boxes 29 that are away from each other. The first limiting rollers 2901 and 2902 in each set of first limiting rollers 2901 are fixedly mounted on the sides of the two side brackets 33. There are two 901s and they are arranged up and down. There are also two second limiting rollers 2902 in each group of second limiting rollers 2902 and they are arranged up and down. The two groups of first limiting rollers 2901 on the pulling box 29 roll and abut against the two first guide grooves on the corresponding side brackets 33. The two groups of second limiting rollers 2902 on the pulling box 29 roll and abut against the two second guide grooves on the corresponding side brackets 33. Through the cooperation between the first limiting rollers 2901 and the first guide rails 3301 and the cooperation between the second limiting rollers 2902 and the second guide rails 3302, the supporting platform 28 and the pulling box 29 are limited between the two side brackets 33 and can only slide in the vertical direction. A plurality of direction wheels 39 are rotatably mounted on the top frame 35, a lifting motor 30 is fixedly mounted on one of the side brackets 33, a roller 41 is keyed to the power output end of the lifting motor 30, the roller 41 is rotatably connected to the side bracket 33, at least two groups of steel ropes 34 are wound around the roller 41, the steel ropes 34 can also be replaced by other ropes that are not easily stretched, the number of steel ropes 34 in each group of steel ropes 34 is two and they are fixedly connected to the two pulling boxes 29 in a one-to-one correspondence, the steel ropes 34 pass around the corresponding direction wheels 39 to change the direction of the steel ropes 34, so that the steel ropes 34 between the pulling boxes 29 and the direction wheels 39 are vertical The state is used to improve the utilization rate of the pulling force of the steel rope 34 on the pulling box 29. When the lifting motor 30 is started to drive the roller 41 to rotate forward, the roller 41 simultaneously reels multiple steel ropes 34, so that the steel ropes 34 pull the load-bearing platform 28 and the two pulling boxes 29 upward. When the lifting motor 30 drives the roller 41 to rotate reversely, the roller 41 simultaneously releases multiple steel ropes 34 to move the load-bearing platform 28 and the two pulling boxes 29 downward. The purpose of setting the steel ropes 34 into multiple groups is to improve the force balance of the load-bearing platform 28 and the pulling box 29, so that the steel ropes 34 can pull the load-bearing platform 28 and the pulling box 29 up and down more smoothly.Two sets of limiting wheels 38 are rotatably mounted on the top frame 35. Each set of limiting wheels 38 contains two limiting wheels 38 located on either side of the hanging rail 37, abutting the sides of the hanging rail 37 to provide low-friction guidance. The support platform 28 and side brackets 33 are slidably mounted on the ground rail 32. A travel motor 31 is also fixedly mounted on the side brackets 33. The power output end of the travel motor 31 is a gear, and the ground rail 32 is provided with a rack that meshes with the gear at the power output end of the travel motor 31. The travel motor 31 drives the gear at its power output end to rotate forward and reverse, causing the water bottle stacking device to reciprocate along the length of the ground rail 32 and hanging rail 37, thereby transporting the packaged water bottles 43. A control box 36 is also fixedly mounted on the side bracket 33, which controls the operation of the lifting motor 30 and the travel motor 31. At the same time, the operation of the two self-locking reduction motors 27 can be controlled by the control box 36 or not. When the control of the control box 36 is not required, the operator can control the start and stop of the two self-locking reduction motors 27 by observation. The above structure and principle of driving the load platform 28 to move up and down and reciprocating along the length of the ground rail 32 are all prior art. Other methods can also be used to achieve the up and down movement of the load platform 28 and the reciprocating movement of the load platform 28 along the length of the ground rail 32, which will not be described in detail.

[0059] In this embodiment, there are two slide rails 2 and they are arranged in parallel along the length direction of the ground rail 32. The slide rails 2 are fixedly mounted on the top of the load-bearing platform 28. A fork is slidably provided on each slide rail 2. The two slide rails 2 are used to guide and support the two forks. The forks slide along the length direction of the slide rails 2. The forks are used to insert into the bottom of the pallet 42 to lift the pallet 42 and the multiple packaged water bottles 43 stacked on the pallet 42. The vertical cross-section of the slide rail 2 is "T"-shaped. The fork is provided with a lower T-shaped slide groove that is compatible with the "T"-shaped structure of the slide rail 2. The slide rail 2 is slidably plugged into the lower T-shaped slide groove. The "T"-shaped structure design of the slide rail 2 and the lower T-shaped slide groove is utilized, so that the fork slides along the length direction of the slide rail 2 while being engaged with the slide rail 2, so that the fork and the slide rail 2 will not separate, thereby realizing the support of the fork by the slide rail 2. The fork comprises a sliding fork 1 and a supporting fork 3 which are elastically slidably arranged. The sliding fork 1 is located between the slide rail 2 and the supporting fork 3. Both the slide rail 2 and the supporting fork 3 are slidably engaged with the sliding fork 1. An upper T-shaped slot and a lower T-shaped slot are formed on the sliding fork 1. The upper T-shaped slot and the lower T-shaped slot are symmetrically arranged. A T-shaped structure which is adapted to and slidably engaged with the upper T-shaped slot is formed on the supporting fork 3 so that the supporting fork 3 can slide relative to the sliding fork 1 without separating. The sliding fork 1 has a guiding and supporting effect on the supporting fork 3. The top surface of the supporting fork 3 is located above the sliding fork 1 for contact with the pallet 42. A row of teeth 101 is fixedly provided on the bottom of the sliding fork 1. There are two self-locking drive mechanisms which correspond one to one with the two sliding forks 1. The self-locking drive mechanism comprises a self-locking reduction motor 27 fixedly mounted in the carrier platform 28. The self-locking method of the self-locking reduction motor 27 is achieved by the meshing of a worm gear. This is a prior art and will not be described in detail. A gear 16, meshing with a row of teeth 101, is fixedly mounted on the power output shaft of the self-locking reduction motor 27. Gear 16 is coaxial with the power output shaft of the self-locking reduction motor 27, driving gear 16 to rotate when the self-locking reduction motor 27 is activated. The self-locking function of the self-locking reduction motor 27 locks gear 16 when it is not rotating, preventing the sliding fork 1 from sliding. Gear 16 can rotate both forward and reverse. When gear 16 rotates, it engages with the row of teeth 101 to drive the sliding fork 1 to slide back and forth. The sliding fork 1 and the support fork 3 slide elastically, forcing the two forks into contact in the sliding direction due to the elastic force between the sliding fork 1 and the support fork 3. Due to the elastic force and friction between the sliding fork 1 and the support fork 3, the sliding fork 1 moves the support fork 3 synchronously. When the support fork 3 carries a tray 42 and a packaged water bottle 43, the support fork 3 drives the tray 42, the packaged water bottle 43, and the sliding fork 1 to move synchronously.The sliding fork 1 is provided with two rows of teeth 101. The power output shaft of the self-locking reduction motor 27 is fixed with two gears 16, which mesh with the two rows of teeth 101 on the sliding fork 1 in a one-to-one manner. The slide rail 2 is located between the two rows of teeth 101, thereby improving the force balance of the sliding fork 1. The two self-locking reduction motors 27 start and stop synchronously to enable the two sliding forks 1 to slide and lock synchronously. The support platform 28 is provided with a corresponding avoidance opening 2801 for the gear 16. The gear 16 passes through the corresponding avoidance opening 2801 and meshes with the corresponding row of teeth 101.

[0060] In this embodiment, each support fork 3 is fixedly mounted with a column 4, and a pressing piece for pressing the packaged water bottle 43 downward is elastically rotatably mounted on the column 4, and the pressing piece is elastically rotatably connected to the two columns 4. In the initial state, the pressing piece is tilted downward based on the elastic force between the pressing piece and the column 4, so that the pressing piece does not contact the top of the packaged water bottle 43. A rope 8 is connected between the pressing piece and the sliding fork 1. The rope 8 is a steel wire rope or a nylon rope or other rope made of a material that is bendable and not easily stretched and deformed. The rope 8 is used to pull the pressing piece downward to rotate so that the pressing piece abuts against the top of the packaged water bottle 43 and presses the packaged water bottle 43 downward. The tension of the rope 8 is provided by the sliding fork 1;

[0061] A limit plate 201 is fixedly provided on each slide rail 2, and the two limit plates 201 are in abutment with the two upright posts 4 in a one-to-one manner. When the fork is inserted into the bottom of the pallet 42 and the pallet 42 and the packaged water bottles 43 are lifted, the self-locking drive mechanism drives the sliding fork 1 to slide toward the load-bearing platform 28, driving the upright posts 4 to continuously approach the limit plates 201 until they abut against the ends of the limit plates 201, so that the upright posts 4 are limited by the limit plates 201. Thereafter, the sliding fork 1 slides while the slide rail 2 and the limit plates 201 do not move, so that relative sliding occurs between the sliding fork 1 and the slide rail 2. At this time, the rope 8 generates tension, so that the rope 8 pulls down the pressing piece to squeeze and reinforce the packaged water bottles 43;

[0062] The working principle of the above structure is as follows: first, the travel motor 31 is started to drive the carrying platform 28 to move horizontally to the packaged water bottles 43 to be transported, and the packaged water bottles 43 are placed on the pallet 42 in a stacked manner. Then, the lifting motor 30 is started to drive the carrying platform 28 to move upward or downward so that the top surfaces of the two support forks 3 are located below the bottom surfaces of the pallet 42. Then, the two self-locking reduction motors 27 are started to drive the gear 16 to rotate forward. The gear 16 uses the engagement with the row of teeth 101 to drive the corresponding sliding fork 1 and the support fork 3 to move synchronously in the direction away from the carrying platform 28 so that the fork composed of the sliding fork 1 and the support fork 3 is inserted into the pallet 42, and the lower pressing piece is located above the packaged water bottle 43 and does not cause obstruction to the packaged water bottle 43. When the fork moves to a certain position, the lifting motor 30 is started again to drive the carrying platform 28 to move upward so that the fork lifts the pallet 42 and the packaged water bottle 43. Then, the self-locking reduction motor 27 is started again to drive the gear 16 to rotate in the opposite direction to drive the sliding fork 1 to slide toward the carrying platform 28. The sliding fork 1 drives the supporting fork 3, the tray 42, and the packaged water bottles 43 to move synchronously toward the carrying platform 28. Based on the fixed connection between the column 4 and the supporting fork 3 and the connection between the pressing member and the column 4, the column 4 and the pressing member move synchronously with the supporting fork 3. During the movement, the column 4 continuously approaches the corresponding limiting plate 201. When the end surface of the column 4 abuts against the limiting plate 201, the supporting fork 3 is limited. Thereafter, the sliding fork 1 continues to slide while the supporting fork 3, the column 4, the rope 8, and the pressing member stop moving with the sliding fork 1. As a result, relative movement occurs between the sliding fork 1 and the supporting fork 3, causing the sliding fork 1 to continuously pull down the rope 8. The downward force exerted on the rope 8 is transmitted to the pressing member, which pulls the pressing member downward (i.e., rotates it toward the packaged water bottle 43) until the pressing member presses against the top of the packaged water bottle 43. Under the action of the downward pressure, the friction between the multiple packaged water bottles 43 increases, making relative movement difficult. The travel motor 31 is then started again to drive the packaged water bottles 43 to move, so that the packaged water bottles 43 are transported to the designated location. The increased friction between the multiple packaged water bottles 43 increases their safety and can increase the conveying speed of the packaged water bottles 43, thereby improving conveying efficiency.

[0063] Thus, in this embodiment, by improving the fork structure and adding a downward pressure member, the self-locking drive mechanism cleverly utilizes the relative displacement between the sliding fork 1 and the supporting fork 3 during the process of retracting the packaged water bottles 43 onto the support platform 28, automatically achieving downward pressure on the packaged water bottles 43 by the downward pressure member. This downward pressure increases the friction between the multiple packaged water bottles 43, thereby improving safety during transportation and increasing the conveying speed of the packaged water bottles 43, thereby enhancing transportation efficiency. Because the action of reinforcing the packaged water bottles 43 is performed while the self-locking drive mechanism drives the fork to retract the packaged water bottles 43 onto the support platform 28, the two actions are seamlessly connected, requiring no operator control, no independent drive for the downward pressure member, and no separate control system for it. This saves costs and reduces the difficulty of control system design, while also effectively reducing the connection time between the two actions, thereby improving work efficiency, effectively addressing the shortcomings of the prior art.

[0064] The pressing member includes a swing plate 9 elastically rotatably arranged with the column 4 , a pressing plate 25 fixedly mounted on the swing plate 9 , and an air bag 26 sealed and fixedly mounted on the bottom of the pressing plate 25 . The two support columns 10 are fixedly mounted on the outer sides of the two support columns 4. The first support column 10 is fixedly mounted on the side of the two support columns 4 away from each other. The swing plate 9 is rotatably connected to the first support column 10. The lower pressure plate 25 is fixedly mounted between the two swing plates 9. The bottom of the lower pressure plate 25 is fixedly and sealed with an airbag 26. The connection between the lower pressure plate 25 and the airbag 26 can be achieved by bonding. The airbag 26 is filled with gas. The airbag 26 protrudes from the bottom of the lower pressure plate 25 and is used to abut against the top of the packaged water bottle 43. Under the tension of the rope 8, the airbag 26 squeezes the top of the packaged water bottle 43. By utilizing the deformability of the airbag 26, when the airbag 26 presses down the packaged water bottle 43, the airbag 26 undergoes adaptive deformation, so that the airbag 26 can generate squeezing force on multiple packaged water bottles 43 located on the top layer, thereby improving the reinforcement range and effect.

[0065] Furthermore, since the pressing member is mounted on the column 4 in an elastically rotatable manner, when the pressing member does not press down the packaged water bottle 43, the pressing member will shake up and down as the support platform 28 moves horizontally or up and down, resulting in a problem of poor stability of the stacking device. In order to prevent the pressing member from shaking when it does not press down the reinforced packaged water bottle 43, in this embodiment, Figure 8As shown, a slider 5 is slidably mounted on the swing plate 9, a downward rotation limit block 502 is fixedly mounted on the slider 5, a first compression spring 12 is installed between the downward rotation limit block 502 and the column 4, a fixed plate 6 is fixedly mounted on the column 4, and a contact plane 601 and an inclined surface 602 are formed at the bottom of the fixed plate 6. Due to the elastic force of the first compression spring 12, the top of the downward rotation limit block 502 is initially located below the contact plane 601 and contacts the contact plane 601, preventing the downward pressure member from rotating downward. Specifically, auxiliary plates 7 are fixedly mounted on both swing plates 9. The two auxiliary plates 7 correspond to the two columns 4 one by one and are located on the outside of the two columns 4, as shown in FIG. Figure 10 As shown, a first guide groove 401 is provided on the side of the column 4 facing the corresponding auxiliary plate 7, and a second guide groove 701 corresponding to the first guide groove 401 is provided on the side of the auxiliary plate 7 facing the corresponding column 4. Two sliding wings 501 are symmetrically fixedly installed on the slider 5, one of which is slidably plugged into the first guide groove 401 and the other is slidably plugged into the second guide groove 701, thereby realizing the sliding setting of the slider 5. A downward rotation limit block 502 is fixedly provided on each slider 5, and each column 4 is provided with a stop block 502. A fixed plate 6 is fixedly installed, and the two lower rotation limit blocks 502 correspond to the two fixed plates 6 one-to-one and to the two columns 4 one-to-one. A first compression spring 12 is connected between the lower rotation limit block 502 and the column 4. One end of the first compression spring 12 is fixedly connected to the column 4, and the other end is fixedly connected to the lower rotation limit block 502. Under the action of the elastic force of the first compression spring 12, the lower rotation limit block 502 is located below the fixed plate 6 in the initial state, and the top of the lower rotation limit block 502 is vertically abutted against the bottom of the abutment plane 601, so that the lower pressure piece cannot rotate clockwise;

[0066] Furthermore, a transverse plate 15 is fixedly mounted on the swing plate 9, and an arc-shaped rod 14 is fixedly mounted on the fixed plate 6 and is slidably plugged into the transverse plate 15. A second compression spring 13 is sleeved on the arc-shaped rod 14, and one end of the second compression spring 13 abuts against the fixed plate 6 and the other end abuts against the transverse plate 15. An upper rotation limit block 1401 located below the transverse plate 15 is fixedly mounted on the upper portion of the arc-shaped rod 14. In the initial state, the elastic force of the second compression spring 13 pushes the transverse plate 15 to abut against the upper rotation limit block 1401 so that the lower pressure piece cannot rotate upward. Specifically, the cross plate 15 is fixedly installed between the two swing plates 9. There are two arc-shaped rods 14, which are fixedly connected to the two fixed plates 6 in a one-to-one correspondence. The arc center of the arc-shaped rod 14 is concentric with the rotation center of the lower pressure piece. The two arc-shaped rods 14 slide through the cross plate 15. The two arc-shaped rods 14 are each sleeved with a second compression spring 13. The upper rotation limit block 1401 is located below the swing plate 9 and is used to limit the swing plate 9. The second compression spring 13 is always in a compressed state. In the initial state, the elastic force of the second compression spring 13 drives the bottom of the two swing plates 9 to abut against the top of the two upper rotation limit blocks 1401 in a one-to-one correspondence, thereby preventing the lower pressure piece from rotating upward. Since the lower pressure piece cannot rotate upward or downward in the initial state, it is locked and will not shake, thereby improving the stability of the stacking device.

[0067] Furthermore, in order to solve the technical problem that the pressing member does not shake in the initial state, the pressing member cannot rotate downward, and the inability to rotate downward makes it impossible for the pressing member to press down the packaged water bottle 43. Therefore, before pressing down the packaged water bottle 43, the limit of the lower rotation limit block 502 on the pressing member must be released. For this reason, in this embodiment, one end of the rope 8 is fixedly connected to the slider 5 and the other end is fixedly connected to the sliding fork 1. A first directional wheel 18 is rotatably provided on each swing plate 9, and a second directional wheel 19 is rotatably provided on each sliding fork 1. There are two ropes 8, and the two ropes 8 are connected to the two sliding forks 1, the two swing plates 9, and the two The slider 5, the two first directional wheels 18, and the two second directional wheels 19 correspond one to one. The purpose is that the two ropes 8 simultaneously generate a downward pulling force on the pressing piece to improve the force balance of the pressing piece. The rope 8 abuts and passes over the first directional wheel 18 and the second directional wheel 19, thereby changing the direction of the rope 8 so that the rope 8 generates a pulling force on the slider 5 parallel to the sliding direction of the slider 5. The elastic force of the first compression spring 12 is smaller than the second compression spring 13. After the column 4 abuts against the limit plate 201, the continued sliding of the sliding fork 1 first drives the rope 8 to pull the downward rotation limit block 502 to move below the inclined surface 602 to release the limit of the downward rotation limit block 502 on the pressing piece. A connecting bolt 102 is fixedly installed on the side of the two sliding forks 1 away from each other. The two ropes 8 are fixedly connected to the two connecting bolts 102 in a one-to-one correspondence, and then pass over the corresponding second directional wheel 19 and the first directional wheel 18 in turn and are then fixedly connected to the corresponding slider 5. The rope 8 is always in a tensioned state. Based on the above structural design, as Figures 13 to 14As shown, in the process of the fork driving the packaged water bottle 43 to be retracted onto the supporting platform 28, after the column 4 abuts against the limit plate 201, the elastic force of the second compression spring 13 is much greater than the first compression spring 12. As the sliding fork 1 slides, the rope 8 first pulls the slider 5 toward the column 4, and the lower pressing piece does not rotate. As the slider 5 slides, the lower rotation limit block 502 is driven to move toward the inclined surface 602, and the first compression spring 12 is compressed and deformed. When the slider 5 is pulled to the set position, the lower rotation limit block 502 is located below the inclined surface 602, and the inclined surface 602 is tilted upward, so that the top of the lower rotation limit block 502 does not contact the inclined surface 602. At this time, the lower rotation limit block 502 no longer limits the lower pressing piece, so that the lower pressing piece has space to rotate downward, as shown in FIG. Figures 14 to 15 As shown, as the sliding fork 1 continues to slide, the rope 8 transmits the tension to the pressing member, which drives the pressing member to rotate downward so that the air bag 26 on the pressing member squeezes and secures the packaged water bottle 43. When the pressing member rotates downward, the first compression spring 12 can deform itself, thereby not hindering the downward rotation of the pressing member.

[0068] It can be seen that in this application, in the process of the fork driving the packaged water bottle 43 to be retracted to the supporting platform 28, not only can the connection between the rope 8 and the sliding fork 1 be used to automatically realize the downward pressure of the packaged water bottle 43 by the down-pressing member, but also the connection between the rope 8 and the slider 5 is cleverly used to automatically realize the unlocking of the down-pressing member, and the unlocking action of the down-pressing member and the downward pressure action of the down-pressing member are also seamlessly connected, eliminating the operation of separately unlocking the down-pressing member, further improving work efficiency, and the unlocking and pressing of the down-pressing member are both generated by the tension of the rope 8, so that the rope 8 "kills two birds with one stone", thereby producing unexpected technical effects in the process of the fork retracting the packaged water bottle 43 to the supporting platform 28.

[0069] In this embodiment, in order to reduce the friction between the lower rotation limit block 502 and the abutment plane 601, multiple balls (not shown in the figure) can be rolled and embedded on the top of the lower rotation limit block 502, and the multiple balls are in contact with the abutment plane 601.

[0070] Among them, a blocking block 11 is fixedly installed on the swing plate 9. In the process of the rope 8 pulling the slider 5 to slide, the slider 5 and the blocking block 11 gradually approach and abut against each other to limit the slider 5. When the slider 5 abuts against the blocking block 11, the downward limit block 502 is located below the inclined surface 602. Based on the limitation of the slider 5 by the blocking block 11, the continued sliding of the sliding fork 1 drives the rope 8 to pull the swing plate 9 and the cross plate 15 to rotate. The rotation of the cross plate 15 squeezes the second compression spring 13 to compress the airbag 26 to squeeze the packaged water bottle 43 downward.

[0071] In this embodiment, a pier plate 301 is fixedly installed at the end of the supporting fork 3, and an abutment plate 302 that abuts with the end of the sliding fork 1 is fixedly installed on the pier plate 301. There are two abutment plates 302 fixedly installed on the pier plate 301 and they are symmetrically arranged. A tension spring 17 is fixedly connected between the pier plate 301 and the sliding fork 1. One end of the tension spring 17 is fixedly connected to the pier plate 301 and the other end is fixedly connected to the sliding fork 1. The tension spring 17 is always in a stretched state. Based on the friction between the supporting fork 3 and the sliding fork 1 and the elastic force of the tension spring 17, the abutment plate 302 abuts with the sliding fork 1 in the initial state. When the fork lifts the pallet 42 carrying the packaged water bottle 43 and drives the packaged water bottle 43 to be retracted to the supporting platform 28, the sliding fork 1 drives the supporting fork 3 to move synchronously, and the supporting fork 3 drives the pallet 42 and the packaged water bottle 43 to move synchronously with the supporting fork 3.

[0072] At the same time, when the packaged water bottle 43 is transported to the designated position such as the cargo compartment opening, the packaged water bottle 43 needs to be delivered to the cargo compartment. First, the self-locking drive mechanism is started to drive the sliding fork 1 to slide in the direction away from the supporting platform 28. At this time, based on the elastic force of the tension spring 17, when the self-locking drive mechanism drives the sliding fork 1 to slide in the direction away from the supporting platform 28, the end face of the sliding fork 1 gradually abuts against the abutment plate 302 to restore the positional relationship between the sliding fork 1 and the support fork 3 to the initial state. After that, the sliding fork 1 drives the support fork 3 carrying the packaged water bottle 43 to move synchronously toward the inside of the cargo compartment to place the packaged water bottle 43 into the cargo compartment. After that, the supporting platform 28 moves down to make the support legs at the bottom of the tray 42 abut against the bottom surface of the cargo compartment. Finally, the cargo fork is retracted onto the supporting platform 28.

[0073] Second embodiment:

[0074] like Figure 1-10 , 16-19, this embodiment includes all the structures of the first embodiment, except that:

[0075] When the support fork 3 is in contact with the limiting plate 201, the free end of the limiting plate 303 is pressed against the side of the extension plate 303, thereby clamping the support fork 3 between the limiting plate 201 and the limiting plate, so that the support fork 3 will not shake when the packaged water bottle 43 is transported, thereby further improving the stability of the packaged water bottle 43 during transportation. Specifically, when the fork is inserted into the bottom of the pallet 42, the limiter and the fork can be inserted into the bottom of the pallet 42 together. Due to the elastic sliding connection between the support fork 3 and the sliding fork 1, the support fork 3 is prone to shake when the packaged water bottle 43 is transported under the action of elasticity. If the support fork 3 shakes, the packaged water bottle 43 will also shake.

[0076] In this embodiment, by adding a pushing plate 20 and a limiting member, when the fork drives the packaged water bottle 43 to be retracted to the supporting platform 28, the pushing plate 20 is driven to squeeze the limiting member to automatically achieve the clamping limit of the supporting fork 3, so that the supporting fork 3 will not shake when the packaged water bottle 43 is being transported, thereby further improving the stability of the packaged water bottle 43.

[0077] like Figure 16-19 As shown, the push plate 20 includes an integrally arranged seesaw plate 2001 and a parallel plate 2002. The parallel plate 2002 is parallel to the sliding direction of the sliding fork 1. The limiting member includes a roller 24 that abuts against the bottom surface of the seesaw plate 2001 and the bottom surface of 2202. When the lower pressing member rotates downward to squeeze the packaged water bottle 43, the roller 24 abuts against the bottom surface of the parallel plate 2002 so that the free end of the limiting member squeezes the extension plate 303. Specifically, the limiting member also includes a pressure rod 21. The roller 24 is rotatably arranged at the end of the pressure rod 21 away from the extension plate 303. The end of the pressure rod 21 close to the extension plate 303 is a free end. A second support column 22 is fixedly installed on the side of the two slide rails 2 that are away from each other. The two pressure rods 21 are rotatably connected to the two second support columns 22 in a one-to-one corresponding manner, as shown in FIG. Figure 17As shown, a stopper 23 is fixedly installed on the side of the two slide rails 2 that are away from each other. The stopper 23 is located on the right side of the second support column 22. The weight of the pressure rod 21 on the right side of the second support column 22 is greater than the weight of the pressure rod 21 on the left side of the second support column 22, so that the bottom of the pressure rod 21 is in contact with the stopper 23 in the initial state. At this time, the highest height of the bottom surface of the rocker 2001 is greater than the top height of the roller 24. As the sliding fork 1 continues to slide toward the supporting platform 28, it drives the push plate 20 continuously approaches roller 24, and then the outer surface of roller 24 abuts the bottom surface of rocker plate 2001. Then rocker plate 2001 pushes roller 24 downward to rotate the free end of pressure rod 21 upward. During this process, limit plate 201 abuts against column 4. Then roller 24 passes over rocker plate 2001 and abuts against the bottom surface of parallel plate 2002, so that the free end surface of pressure rod 21 abuts against extension plate 303, thereby clamping support fork 3 between limit plate 201 and the limiter. Thereafter, as sliding fork 1 continues to slide, the outer surface of roller 24 always abuts against the bottom surface of parallel plate 2002 until sliding fork 1 moves to a specific position, causing airbag 26 to press downward against packaged water bottle 43.

[0078] Similarly, when the packaged water bottle 43 is transported to a designated position such as the cargo compartment opening, when the packaged water bottle 43 needs to be delivered to the cargo compartment, as the sliding fork 1 slides in the direction away from the supporting platform 28, before the sliding fork 1 abuts against the abutment plate 302, based on the abutment between the roller 24 and the bottom surface of the parallel plate 2002, the pressure rod 21 maintains the limit on the support fork 3. Under the limiting action of the limiting member, when the sliding fork 1 slides in the direction away from the supporting platform 28, the support fork 3 will not move so that the relative position between the sliding fork 1 and the support fork 3 can be restored to the initial state more smoothly, and the elastic sliding connection between the sliding fork 1 and the support fork 3 will not cause the sliding fork 1 to shake during the sliding process of the support fork 3, so that the support fork 3 remains in a stable state to achieve the reset of the relative position between the sliding fork 1 and the support fork 3.

[0079] It can be seen from this that the limiting member not only limits the support fork 3 during the transportation of the packaged water bottle 43, but also, when the packaged water bottle 43 is transported into the cargo grid by the cargo fork, based on the abutment between the roller 24 and the bottom surface of the parallel plate 2002, the support fork 3 is still clamped and limited during the process of the relative position between the sliding fork 1 and the support fork 3 being restored to the abutment state, thereby preventing the support fork 3 from shaking.

[0080] By utilizing the rotation of the roller 24 , the friction between the parallel plate 2002 and the limiting member can be reduced during the movement of the parallel plate 2002 .

[0081] In the process of the relative position between the sliding fork 1 and the supporting fork 3 returning to the initial state, on the one hand, the elastic force of the second compression spring 13 is released to make the lower pressure piece rotate upward, thereby relieving the squeezing of the packaged water bottle 43 until the upper rotation limit block 1401 re-abuts against the swing plate 9; on the other hand, the elastic force of the first compression spring 12 is released to push the slider 5 to slide, so that the lower rotation limit block 502 moves to below the abutment plane 601, so that the lower pressure piece is limited again to prevent the lower pressure piece from shaking when the fork is inserted into the cargo grid.

[0082] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
