Description

Technical Field

[0001] The invention relates to the technical field of stacking devices, and in particular to bottled water stacking equipment based on a stacking alignment auxiliary structure. Background Art

[0002] Faced with the market's increasingly diverse demand for bottled water specifications and packaging forms, the production capacity of bottled water palletizing equipment has been continuously enhanced, greatly improving production flexibility and market adaptability. In the bottled water palletizing operation, the alignment link is of great significance. Bottled water itself is heavy. If accurate alignment is not achieved during palletizing, it will cause an imbalance in the force between the barrels, seriously affecting the stability of the palletizing structure, and it is very easy to collapse during the subsequent handling and storage stages, which will not only cause direct damage and economic losses to the bottled water, but may also cause serious safety accidents and threaten the safety of personnel and equipment.

[0003] During the transportation of bottled water, the barrel mouth is only fixed at a single point by a mechanical clamping device. Due to the lack of circumferential constraints, the barrel body will undergo non-uniform stress distribution under the action of dynamic loads. The barrel body is prone to radial deformation due to insufficient material stiffness. The deformation of the barrel body will destroy the preset geometric matching relationship of the stacking. The friction force on the contact surface between layers is unevenly distributed, which increases the risk of slippage and dislocation. At the same time, the abnormal shape of the barrel body may prevent adjacent barrels from contacting each other as expected. As the stacking is built, the dislocation will spread to the entire stacking structure, which will not only affect the visual neatness of the stacking, but also seriously damage the stability of the stacking and increase the risk of collapse during transportation and storage. Summary of the invention

[0004] Technical issues solved In view of the above-mentioned shortcomings of the prior art, the present invention provides a bottled water palletizing device based on a palletizing alignment auxiliary structure, which can effectively solve the problem of deformation of bottled water in transportation and subsequent misalignment during palletizing in the prior art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides a bottled water palletizing device based on a palletizing alignment auxiliary structure, comprising: Robotic arm; A transfer plate, the transfer plate is located at one end of the mechanical arm and covers the stacking frame; A clamping part, the clamping part is located on the lower surface of the transfer plate, the clamping part includes a clamp for fixing and limiting the barrel mouth, a truncated cone frame for limiting the upper surface of the barrel body is provided at the bottom of the clamp, and a protective frame for positioning the outer wall of the barrel body is provided at the bottom of the truncated cone frame; Wherein, the frustum frame comprises side plates which can be adjusted at different angles according to the different locking states of the barrel mouth by the clamp.

[0006] Furthermore, the clamp includes a sleeve that is mounted on the barrel mouth, a clamping block that moves up and down is provided at the top of the inner wall of the sleeve, a pressure block is provided on the inner wall of the sleeve, and the pressure block slides along a slide groove opened on the inner wall of the sleeve under the control of the hydraulic system, and the bottom end of the pressure block is fixedly connected to a fixed block that is movably connected to the top of the truncated cone frame.

[0007] Furthermore, the frustum frame includes a limiting ring fixedly connected to the bottom end of the sleeve, the inner wall of the limiting ring is provided with a second slide groove, the inner wall of the second slide groove is slidably connected with a positioning plate, the top of the positioning plate is fixedly connected to the fixed block, the bottom end of the positioning plate is fixedly connected with an inclined wedge block, a fixing rod is provided through the middle of the inclined wedge block, the other end of the fixing rod is fixedly connected to a bottom block, a telescopic spring is elastically connected to a side of the inclined wedge block close to the bottom block, the bottom block is located at the bottom end of the second slide groove, and the bottom block is rotated by a knob spring embedded in the inner wall thereof and damped by the side plate.

[0008] Furthermore, the inner wall of the side panel is detachably connected with a pressure layer, the bottom end of the side panel is fixedly connected with a limit block, a limit groove is opened inside the limit block to facilitate the up and down movement of the protective frame, and the inner wall of the limit block is provided with a rubber plate to control the movement state of the limit groove.

[0009] Furthermore, the protective frame includes a protective outer plate that is slidably connected to the inner wall of the limiting groove, a blocking plate is fixedly connected to the bottom end of the protective outer plate, the size of the blocking plate is larger than the size of the protective outer plate, the inner wall of the blocking plate is evenly provided with blocking blocks for multi-point extrusion of the outer wall of the barrel body, a magnetic plate is provided on the top of the blocking plate, and the inner wall of the protective outer plate is flexibly connected with a telescopic layer.

[0010] Furthermore, a long plate is symmetrically fixed to one side of the rubber plate close to the limiting groove, and two magnetic blocks with opposite magnetic properties are fixedly connected to the bottom end of the long plate, and the magnetic blocks are magnetically connected to the magnetic plate.

[0011] Furthermore, an extrusion plate is arranged on one side opposite to the long plate, and the extrusion plate adopts a side tilting design.

[0012] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention is provided with a clamp to clamp and fix the barrel mouth. While the barrel mouth is fixed, the angle of the truncated cone frame is changed until the truncated cone frame fits with the inclined surface of the barrel mouth, and the upper surface of the barrel body is pressed and limited to avoid radial changes.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] Example:

[0020] See also Figure 1-Figure 7 The present invention provides a technical solution for bottled water palletizing equipment based on a palletizing alignment auxiliary structure: Figure 1 As shown, the device includes a robotic arm 1, the other end of which is fixedly connected to a transfer plate 2. The robotic arm 1 drives the transfer plate 2 to move up and down. A clamping portion 3 is provided on the lower surface of the transfer plate 2. The clamping portion 3 is provided in multiple numbers and in a row. The clamping portion 3 can move back and forth on the lower surface of the transfer plate 2.

[0021] In actual production, in the process of palletizing bottled water, the bottled water is fixed by mechanically clamping the barrel mouth. Since the mechanical clamping only acts on the barrel mouth, the barrel body lacks effective support and constraints from other parts. Under the action of inertia and external force, it will produce a large amount of shaking, resulting in uneven force on various parts of the barrel body, especially the part far away from the barrel mouth where the force is more complicated, which greatly increases the risk of deformation of the barrel body. Once the barrel body is deformed, it will further increase the difficulty of subsequent alignment. The size and shape of the deformed barrel body change, and there is a deviation from the standard barrel body. In the process of stacking and alignment, it cannot accurately match the preset stacking mode and position, which makes it difficult to arrange adjacent bottled water tightly and neatly. Even if the stacking is originally well aligned, the misalignment caused by the deformation of the barrel body will continue to accumulate as the number of stacking layers increases, seriously damaging the stability and neatness of the stack, and even causing the stack to collapse during transportation or storage. In view of this, the clamping portion 3 provided by the present invention, in addition to clamping the barrel mouth, also has a conical frame 32 for limiting the upper inclined surface of the barrel body, and a protective frame 33 for limiting the outer wall of the barrel body. Compared with the fixing method of only mechanically clamping the barrel mouth, the above design shows significant advantages in many aspects such as barrel body protection, transportation stability, stacking alignment, and versatility, which can effectively reduce the risk of barrel body deformation and improve the stacking effect.

[0022] refer to Figure 2 and Figure 3The clamping part 3 includes a clamp 31 that is transmission-connected to the lower surface of the transfer plate 2. The clamp 31 includes a sleeve 311 sleeved on the outer wall of the barrel mouth. A clamp block 313 for limiting the top of the barrel mouth is provided at the top of the inner wall of the sleeve 311. The clamp block 313 can limit the barrel mouth. The clamp block 313 adopts a concave bowl-shaped design. The clamp block 313 can not only adapt to the shape of the water inlet at the upper part of the barrel mouth, but also accurately limit the water inlet to a specific position, so that the barrel will not shake left and right or jump up and down during the transfer process, thereby ensuring the stability of the barrel mouth and reducing the risk of water overflow caused by shaking. It can also effectively prevent the barrel body from being offset due to external force, ensuring that the barrel body is always in the correct position. The arrangement is convenient for subsequent stacking, handling and other operations, and improves the accuracy and efficiency of the entire operation process. At the same time, the clamping block 313 can play a buffering role when the barrel mouth collides with other objects, reduce the direct impact force of the collision on the barrel mouth and the water inlet, reduce the possibility of barrel mouth rupture, deformation and water inlet damage, and extend the service life of the barrel. A circular pressure block 312 is arranged at the lower position of the inner wall of the sleeve 311. In the initial state, the pressure block 312 is embedded in the inner wall of the sleeve 311, and then under the action of the hydraulic system, the pressure block 312 moves toward the center of the sleeve 311 along a slide groove 315 opened on the inner wall of the sleeve 311 to squeeze and fix the outer wall of the barrel mouth.

[0023] In the initial state, the clamp 31 is in an open state, and the truncated cone frame 32 and the protective frame 33 linked thereto are both in an open state, so that barrels of different specifications can be inserted therein. In actual production, large-sized bottled water requires greater stability to prevent tipping, so the angle of the slope is smaller to lower the center of gravity. The design of small-sized bottled water pays more attention to the convenience of tipping, so the angle of the slope is larger to facilitate pouring. Therefore, the corresponding angle of the truncated cone frame 32 is set according to the size of the barrel body of different specifications.

[0024] refer to Figure 2 , Figure 3 and Figure 4 The bottom end of the pressing block 312 is fixedly connected to a fixing block 316 movably connected to the top of the truncated cone frame 32. The truncated cone frame 32 includes a limiting ring 321 fixedly connected to the bottom end of the sleeve 311. The inner wall of the limiting ring 321 is provided with a second slide groove 322. The inner wall of the second slide groove 322 is slidably connected to a positioning plate 323 fixedly connected to the bottom end of the fixing block 316. The positioning plate 323 is provided with an arc-shaped rubber layer on one side close to the center of the limiting ring 321. In the initial state, in the vertical plane, As for the side profiles of the positioning plate 323 and the pressing block 312, the side of the positioning plate 323 located below has a larger protrusion in the horizontal direction than the side of the pressing block 312 above it, showing a more convex shape feature of the side of the positioning plate 323 below. The top of the positioning plate 323 is fixedly connected to the bottom of the pressing block 312, and the pressing block 312 drives the positioning plate 323 to move. The positioning plate 323 limits the bottom of the barrel mouth, thereby achieving all-round fixation of the top, side and bottom of the barrel mouth. refer to Figure 4 and Figure 5 The bottom end of the positioning plate 323 is fixedly connected with an inclined wedge block 324, a fixing rod 3241 is arranged through the middle of the inclined wedge block 324, and the other end of the fixing rod 3241 is fixedly connected with a bottom block 3251, and a telescopic spring 3242 is elastically connected to the side of the inclined wedge block 324 close to the bottom block 3251, and the bottom block 3251 is located at the bottom end of the second slide groove 322, and the bottom block 3251 is damped by the knob spring 3252 embedded in its inner wall and the side plate 325 for rotation, and the inner wall of the side plate 325 is detachably connected with a pressurizing layer 326, and the bottom end of the side plate 325 is fixedly connected with a limiting block 327, and a limiting groove 328 is opened inside the limiting block 327 for facilitating the upward and downward movement of the protective frame 33, and a rubber plate 329 for controlling the moving state of the limiting groove 328 is arranged on the inner wall of the limiting block 327.

[0025] The pressure block 312 and the clamping block 313 in the sleeve 311 and the positioning plate 323 on the inner wall of the truncated cone frame 32 operate synchronously to complete the all-round limiting protection of the barrel mouth. At the same time, the positioning plate 323 drives the inclined wedge block 324 fixedly connected to its bottom end to slide along the fixed rod 3241. The inclined wedge block 324 overcomes the elastic force of the telescopic spring 3242 and moves while squeezing the upper surface of the side plate 325. Therefore, while the pressure block 312 drives the positioning plate 323 to limit the barrel mouth of a smaller size, the side plate 325 rotates toward the side close to the barrel body under the action of the squeezing force of the inclined wedge block 324, changing the angle of the side plate 325 that originally fits tightly to the upper surface of the large-sized barrel body, so that it fits tightly to the upper surface of the small-sized barrel body.

[0026] From the perspective of barrel body protection, the truncated cone frame 32 limits the upper inclined surface of the barrel body, changing the stress condition of a single barrel mouth. During the transfer process, the external force on the barrel body can be more evenly dispersed through the truncated cone frame 32, greatly reducing the risk of deformation of the barrel body due to excessive local force. When subjected to a large external force during the stacking and transfer process, the upper inclined surface of the barrel body is stably supported by the truncated cone frame 32, avoiding deformation problems such as barrel body distortion and depression caused by the barrel mouth being subjected to external force alone, effectively ensuring the integrity of the bottled water packaging; In terms of stability and alignment, this design improves the stability of bottled water during transfer and palletizing. The cone-shaped frame 32 limits the upper inclined surface of the barrel body, and the protective frame 33 limits the edge of the barrel body, forming a multi-point and multi-faceted constraint system. When vibration and shaking occur during the palletizing and transfer process, the bottled water is effectively restricted in multiple dimensions, reducing the possibility of displacement and rotation, and significantly improving the stacking misalignment problem that was originally prone to shaking, so that a more accurate alignment state can be maintained during palletizing. From the perspective of versatility, the angle of the side panel 325 can be adaptively adjusted to accommodate bottled water of different specifications, and is thus widely applicable to bottled water barrels with slightly different diameters, heights and shapes. Compared with a single mechanical clamping method designed only for a specific barrel mouth size, it significantly improves the versatility and applicability of the fixing device, and reduces the cost and time consumption of frequent replacement of fixing equipment due to changes in bottled water specifications.

[0027] The positioning plate 323 limits the bottom of the barrel mouth, and the side plate 325 limits the upper surface of the barrel body, all using the power source of the pressing block 312. Through the ingenious design of the multi-stage structure and reasonable power transmission, the three actions of barrel mouth clamping, inclined clamping, and barrel edge limiting are executed in sequence, meeting the requirements of action sequence and mechanical coupling. From the perspective of equipment integration and maintenance cost, only a single power source is used, which greatly simplifies the architecture of the power system and reduces the number of motors and their supporting control equipment, which not only reduces the initial equipment procurement cost, but also reduces the probability of failure during subsequent long-term use due to the reduction in the number of power sources, and makes maintenance work easier, which significantly reduces the maintenance cost and improves the overall reliability and stability of the equipment. In terms of the accuracy and coordination of motion control, a single power source can provide stable and accurate power output for the three actions with its precise speed and angle control characteristics, ensuring that the three actions of barrel mouth clamping, inclined clamping, and barrel edge limiting are performed in sequence and smoothly in a predetermined order, with tight connection between the actions and excellent coordination. In the barrel mouth clamping stage, the power source accurately controls the clamping force and position of the pressure block 312 to ensure that the barrel mouth is firmly fixed; in the inclined clamping action, the side plate 325 is driven by the structural transmission to accurately adjust the angle, closely fit with the upper inclined surface of the barrel body, and achieve stable limiting; finally, the protective frame 33 effectively protects the outer wall of the barrel body, avoiding damage to the barrel body caused by uncoordinated actions or improper force, and greatly improving the stability and reliability of the barrel water fixation; From the perspective of improving production efficiency, since the three actions are driven by a single power source, in high-speed and continuous production operations, the power source responds to instructions quickly and drives each action to be completed efficiently with stable power output, reducing production pauses caused by delayed or uncoordinated action switching, and greatly improving the production, handling and stacking efficiency of bottled water. For example, in the automated stacking process, the clamp 31 can quickly and accurately fix the bottled water and place it in the designated position, laying a solid foundation for subsequent efficient stacking operations and effectively promoting the automation process of the entire bottled water production process.

[0028] The surface of the truncated cone frame 32 that contacts the upper inclined surface of the barrel body is embedded with a detachable pressurizing layer 326. The anti-skid pattern of the pressurizing layer 326 is designed in a diamond shape, a wave shape, etc., which increases the friction with the barrel body and effectively prevents rotation. The pressurizing layer 326 has good elasticity and friction, can fit closely to the inclined surface of the barrel body, and provide reverse resistance when the barrel body tends to rotate, effectively preventing the barrel body from sliding or rotating relative to the truncated cone frame 32, firmly maintaining the position of the barrel body, greatly improving the fixing stability, and reducing the risk of damage to the barrel body due to displacement and collision; enhancing the versatility of the clamp 31 for barrels of different specifications and materials, and reducing the fixing difficulties caused by the diversity of barrel bodies; it can also buffer external forces when in contact with the barrel body to prevent the truncated cone frame 32 from hard contact and damage to the barrel body. When the rubber particles are worn, aged, or contaminated with difficult-to-clean dirt and affect the anti-skid performance during transportation vibration and mutual squeezing of the barrel bodies, they can be easily taken out and replaced without the need to replace the truncated cone frame 32 as a whole, reducing maintenance costs and time, and making it easier to clean and maintain it.

[0029] In actual production, during the palletizing and transfer process, the inertial force generated by the start, pause, and turn of the palletizing equipment can easily cause the barrel body to rotate around the barrel mouth. The original regular square or rectangular palletizing pattern requires that the sides of the barrel body be arranged in parallel. The rotated barrel body will break this neatness, resulting in gaps and misalignments in the palletizing, reducing space utilization. The contact state between the rotated barrel body and the adjacent barrel body changes, and a tight and stable support structure cannot be formed.

[0030] refer to Figure 5 , Figure 6 and Figure 7 The protective frame 33 includes a protective outer plate 331 that is slidably connected to the inner wall of the limiting groove 328, a blocking plate 332 is fixedly connected to the bottom end of the protective outer plate 331, the size of the blocking plate 332 is larger than the size of the protective outer plate 331, and the inner wall of the blocking plate 332 is evenly provided with blocking blocks 333 for multi-point extrusion of the outer wall of the barrel body, a magnetic plate 334 is provided on the top of the blocking plate 332, and a telescopic layer 335 is flexibly connected to the inner wall of the protective outer plate 331, and a long plate 3291 is symmetrically fixed on one side of the rubber plate 329 close to the limiting groove 328, and two magnetic blocks 3292 with opposite magnetism are fixedly connected to the bottom end of the long plate 3291, and the magnetic blocks 3292 are magnetically connected to the magnetic plate 334, and an extrusion plate 3293 is provided on the opposite side of the long plate 3291, and the extrusion plate 3293 adopts a side tilt design.

[0031] After the side plate 325 rotates to fit the upper surface of the barrel body, the side plate 325 drives the limit block 327 to move synchronously, and the rubber plate 329 on the inner wall of the limit block 327 contacts the outer wall of the barrel body. As the pressure layer 326 presses the barrel body, the rubber plate 329 is subjected to an increased reaction force from the barrel body, and the rubber plate 329 moves toward the limit groove 328. The movement of the rubber plate 329 drives the long plate 3291 to move, and the movement of the long plate 3291 drives the extrusion plate 3293 to move. The side edge of the extrusion plate 3293 is set as an inclined surface. During the movement, The friction force with the outer wall of the protective outer plate 331 gradually decreases. At the same time, the magnetic block 3292 that was originally attracted to the magnetic plate 334 also moves with the long plate 3291. While the limiting effect of the long plate 3291 on the side of the protective outer plate 331 is reduced, the magnetic repulsion of the magnetic block 3292 on the magnetic plate 334 gradually increases, and the protective outer plate 331 moves downward along the limiting groove 328. The protective outer plate 331 moves downward, and the telescopic layer 335 of its inner wall fits the outer wall of the barrel body. The blocking plate 332 moves downward synchronously to limit the lower position of the barrel body wall at multiple points.

[0032] The protective outer plate 331 adopts an outward convex arc design and the inner wall is provided with a symmetrical outward convex arc expansion layer 335. The outward convex arc design enables the protective outer plate 331 to better disperse the external force. When an object collides with the protective frame 33, the arc structure can disperse the impact force in all directions along the arc surface. Compared with the flat structure, it can withstand greater external force without being easily deformed or damaged, thereby extending the service life of the protective frame 33 and ensuring that it can provide good protection for the barrel body during multiple uses; the outward convex arc shape can reduce the contact area with other objects. During the transportation process, If the protective frame 33 rubs against or collides with surrounding objects, the arc-shaped design can reduce the force of scratches and collisions, and reduce damage to the barrel body and the protective frame 33 itself. At the same time, this design can also guide objects to slide along the arc surface, avoiding serious collisions and damage caused by right angles or sharp corners; the convex arc-shaped design can provide a larger containing space for the barrel body without increasing too much lateral size. In a limited space, the protective frame 33 and the barrel body can be placed more reasonably, improving space utilization, which is particularly suitable for bottled water storage and transportation environments with relatively compact space.

[0033] The telescopic layer 335 has good elasticity and can play a buffering role between the barrel body and the protective outer plate 331. During the transportation process, the barrel body may contact the protective frame 33 due to shaking or external force. The telescopic layer 335 can absorb and disperse these impact forces, reduce the vibration of the barrel body, and prevent the barrel body from breaking or being damaged due to collision. The friction force on the surface of the telescopic layer 335 is relatively large, which can make the contact between the barrel body and the protective frame 33 more stable. Even if it encounters bumps or tilts during transportation, the barrel body can better stay in place and is not prone to sliding or shifting, further improving the stability of the barrel body during transportation; the telescopic layer 335 is soft in texture and will not cause scratches or wear on the surface of the barrel body, which can effectively protect the appearance and integrity of the barrel body. Whether it is a plastic barrel or a barrel made of other materials, it can avoid scratches, pits and other damage caused by direct contact with the protective frame 33, keep the barrel body in good condition, and also play a certain role in noise reduction and sound insulation.

[0034] During the stacking process of bottled water, the bottom end of the protective outer plate 331 is fixedly connected to a baffle 332 whose size is larger than the baffle, and a plurality of evenly spaced hemispherical blocks 333 are arranged on the inner wall of the baffle 332. The larger baffle 332 can provide more precise positioning for the bottled water, and ensure that each barrel can be placed in the correct position during stacking, so that the arrangement of the bottled water is more neat and orderly, which is conducive to improving the space utilization rate of stacking, making the stacking more compact and regular, reducing the space waste caused by position deviation, and improving the storage and transportation efficiency. The larger baffle 332 can increase the contact area and stability with the outer wall of the barrel body on the basis of the protective outer plate 331. When stacking multiple layers of bottled water, the support between each layer of barrels can be made more uniform and stable, dispersing the pressure of the upper barrel body on the lower barrel body, reducing the risk of stacking collapse due to unstable center of gravity or excessive local pressure, and ensuring the safety of bottled water during stacking, storage and transportation.

[0035] The hemispherical block 333 can significantly increase the friction between the barrel body and the blocking plate 332. During the stacking process, especially when the stacking is at a certain tilt angle or is subjected to vibration, it can effectively prevent the bottled water from sliding or shifting in the blocking plate 332, ensuring that each barrel can remain in the initial stacking position and maintaining the overall stability and neatness of the stacking. When the barreled water is stacked, the hemispherical block 333 can play a buffering role. When the barrel body contacts the blocking plate 332 or is slightly collided during the stacking process, the block 333 can absorb and disperse the impact force, reducing the hardness between the barrel bodies and between the barrel body and the blocking plate 332. Collision reduces the possibility of barrel rupture, deformation or surface scratches, and protects the quality of the barrel and bottled water; multiple evenly spaced hemispherical blocks 333 make the pressure distribution between the barrel and the baffle 332 more uniform, avoiding pressure concentration or unevenness caused by local tight or loose contact between the barrel and the baffle 332, ensuring that the barrel is supported by a relatively balanced force in all directions, which is beneficial to extending the service life of the barrel and also ensures the stability and safety of palletizing; when the barrel shows signs of rotation, multiple evenly spaced hemispherical blocks 333 can prevent rotation and provide additional constraints for the barrel.
