Description

Technical Field

[0001] This invention relates to the field of palletizing, stacking and transferring technology, and specifically to a palletizing, stacking and transferring device for drums. Background Technology

[0002] Palletizing and stacking are important means of achieving automated packaging and transportation. Palletizing and stacking equipment uses different technologies for different materials. For barrel-shaped materials, the general technology is as follows: first, individual barrel-shaped materials are transported to the stacking device via a conveyor line. The stacking device stacks multiple barrel-shaped materials into stacks arranged vertically. Then, the stacks are transported forward one by one via a conveyor line into the stacking device. The stacking device horizontally stacks the stacks to form a stacking group. Finally, the stacking group, along with pallets, is transported out.

[0003] There are many existing automatic bucket stacking devices. For example, patent application number 201110230183.2, published on April 17, 2013, discloses a palletizing machine and its operating method, including a frame, a lifting bucket assembly, a moving pressing assembly, a positioning cylinder, and a detection switch. The moving pressing assembly includes a guardrail frame, and a pressing cylinder is fixed to the top of the guardrail frame via a connecting plate. The piston rod of the pressing cylinder is fixed to a pressure plate. The effect of adopting the above technical solution is that it changes the adsorption method to a pressing method, and moves the stacked buckets to the pallet through the pressing cylinder and the guardrail frame, thus achieving the purpose of conveying the buckets. There are no restrictions on the surface and strength of the bucket lid, and the operation is safe and reliable.

[0004] The above setup involves a downward-pressing cylinder directly driving a pressure plate to act on the top of the barrel. If the barrel top surface is uneven, or if the barrels are slightly misaligned during multi-row stacking, the pressure plate cannot achieve uniform force distribution, resulting in some barrels not being effectively compressed. This can easily lead to loosening and shifting during subsequent movement or transport. Furthermore, the guardrail has several horizontal plates, the spacing of which is not adjustable. If the stacking height changes, the horizontal plates cannot provide uniform support across the entire stack height, making it prone to sliding during transport and potentially causing relative slippage within the entire stack. Additionally, when the pre-stacked barrels from the barrel assembly outlet are pushed into the lifting barrel assembly, this assembly only supports the barrels via a pallet without any limiting structures. Due to the lack of lateral barriers or other limiting components, the pre-stacked barrels are prone to sliding forward / backward or shifting left / right on the pallet due to inertia under the impact of the push, failing to accurately stop at the preset stacking position.

[0005] In addition, existing stacking equipment pushes material stacks directly onto pallets for horizontal stacking. This results in the pallet surface being subjected to repeated friction after multiple stacks are pushed onto the pallet, which damages the pallet. Furthermore, the pallet also causes wear and tear on the materials. Summary of the Invention

[0006] This invention provides a drum palletizing and stacking transfer device. Utilizing the structure of this invention, the palletizing reliability is high, the wear on the pallets is minimal, and the stacking efficiency is high.

[0007] To achieve the above objectives, the technical solution of the present invention is: a drum palletizing and stacking transfer device, comprising a palletizer and a stacking transfer machine. The palletizer includes a first frame and a material conveying line. The first frame is provided with a drum stacking support assembly, which includes one or more drum stacking working positions. A positioning assembly is provided on the material conveying line. A lifting drum stacking assembly is slidably arranged on the first frame at a corresponding position of the positioning assembly. The positioning assembly and the lifting drum stacking assembly are arranged corresponding to the drum stacking working positions. A material blocking assembly is also provided on the feeding side of the frame.

[0008] The stacker transfer machine includes a second frame, on which are arranged material stack conveyor lines and material stack group transfer lines arranged sequentially according to the material stack conveying direction. The input end of the material stack conveyor line is connected to the output end of the material conveyor line. A stacking space is provided on one side of the material stack group transfer line within the second frame. A pallet conveyor line is provided on the second frame below the stacking space. A movable pusher assembly is provided on the second frame to push the material stack group into the stacking space. A first baffle assembly is provided on the second frame on one side of the stacking space opposite to the movable pusher assembly. A second baffle assembly and a limiting pusher assembly are respectively provided on the second frame on the opposite side of the stacking space. The second baffle assembly is perpendicular to the first baffle assembly. A movable bearing assembly is provided above the pallet conveyor line. The movable bearing assembly includes a bearing drive assembly and a bearing plate slidably disposed on the pallet conveyor line. The bearing drive assembly drives the bearing plate to move. A lifting bearing assembly that can pass through the pallet conveyor line is provided on the pallet conveyor line and below the stacking space.

[0009] With the above setup, after the equipment starts, individual buckets are conveyed into the first frame via the material conveyor line. When the material reaches the corresponding position of the positioning component, the material blocking component activates to limit the end of the bucket and prevent it from moving forward. Subsequently, the positioning component precisely constrains the lateral position of the bucket, corrects its posture, and reduces bucket offset and tilting. After positioning is completed, the lifting stacking component on the first frame corresponding to the stacking work position slides vertically upward, lifting the bucket to the preset stacking height. After the next bucket is conveyed to the same stacking work position via the material conveyor line and completed positioning, the lifting stacking component drives the upper bucket to descend, achieving precise stacking of two layers of buckets. The above actions are repeated to complete the stacking of a single material stack according to the preset number of layers. The formed single material stack is then conveyed by the material conveyor line to the material stack conveyor line of the stacking transfer machine.

[0010] After receiving a single material stack, the material stack conveyor line of the stacker transfer machine integrates several material stacks into a material stack group according to a preset arrangement and transports them to the material stack group transfer line. Then, the bearing drive component moves the bearing plate to the bottom of the stacking space. Next, the moving push plate component moves horizontally towards the stacking space, pushing the material stack groups on the material stack group transfer line one by one onto the bearing plate. During the pushing process, the first baffle component, the second baffle component, and the limiting push plate component reach the preset position first, blocking the stacking space in three directions to prevent the material stack groups entering the stacking space from tipping over, shifting, or scattering. When the number of material stacks reaches a preset quantity, a stacking group is formed. Simultaneously, a pallet is transported to the underside of a support plate via a pallet conveyor line. Alternatively, the pallet can be initially transported to the underside of the support plate, then the stacking group is clamped by a moving pusher assembly and a first baffle assembly. A support drive assembly moves the support plate away from the stacking space, and then a lifting support assembly moves the pallet upwards, disengaging it from the pallet conveyor line. The pallet then carries the stacking group. The clamping of the stacking group by the moving pusher assembly and the first baffle assembly is released, and the lifting support assembly reverses its movement, moving the pallet carrying the stacking group downwards, re-engaging it with the pallet conveyor line. The pallet conveyor line then transports the pallet carrying the stacking group to the next process. Therefore, in this invention, the stacking group is first formed on the support plate, without direct contact with the pallet. After the stacking group is formed, the support plate is removed, and the pallet supports the stacking group under the action of the lifting support assembly, before the stacking group is transported out via the pallet.

[0011] Therefore, in this invention, on the one hand, the material blocking component limits the end of the bucket to prevent it from moving forward; on the other hand, the positioning component precisely constrains the lateral position of the bucket, resulting in better stacking accuracy and higher stacking efficiency. Furthermore, the stacking assembly of this invention falls directly onto the pallet as a whole, minimizing friction with the pallet and reducing wear on the stacking assembly, thus preventing damage to the pallet.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-23 As shown, a drum palletizing and transferring device includes a palletizer, a pallet transfer machine, and a pallet depalletizer. The palletizer is located on one side of the pallet transfer machine, and the pallet depalletizer is connected to the pallet transfer machine.

[0015] The palletizer includes a first frame 1 and a material conveying line 2. Along the flow direction of the material conveying line 2, the side where the material first enters the first frame 1 is the feeding side of the first frame 1. The first frame 1 is provided with a stacking drum support assembly 14, which includes one or more stacking drum working positions 14211. The material conveying line 2 is provided with a positioning assembly 13. The frame 1 is slidably provided with a lifting stacking drum assembly 11 at the corresponding position of the positioning assembly 13. The positioning assembly 13 and the lifting stacking drum assembly 11 are correspondingly arranged with the stacking drum working positions 14211.

[0016] The stacker transfer machine includes a second frame 01, on which a material stack transfer line 03 and a material stack conveyor line 02 are installed. The material stack conveyor line 02 and the material stack transfer line 03 are arranged sequentially in the conveying direction. The output end of the material conveyor line 02 is connected to the input end of the material stack conveyor line 02. A stacking space 04 is located on one side of the second frame 01, below the material stack transfer line 03 and the material stack conveyor line 02. A pallet conveyor line 74 is installed on the second frame 01 below the stacking space 04. Here, "below" refers to directly below and to the side below. One end of the pallet conveyor line 74 extends out of the second frame 01. A movable pusher is installed on the second frame 01 to push the material stack 82 into the stacking space 04. A plate assembly 5; a first baffle assembly 6 is provided on one side of the stacking space opposite to the movable pusher assembly 5 on the second frame 01; a second baffle assembly 60 and a limiting pusher assembly 4 are respectively provided on the opposite side of the stacking space on the second frame 01. The second baffle assembly 60 is perpendicular to the first baffle assembly 6, and the limiting pusher assembly 4 is perpendicular to the first baffle assembly 6. A movable bearing assembly 7 is provided above the pallet conveyor line 74. The movable bearing assembly 7 includes a bearing drive assembly and a bearing plate 71 slidably disposed on the pallet conveyor line. The bearing drive assembly drives the bearing plate 71 to move. A lifting bearing assembly 73 that can pass through the pallet conveyor line is provided on the pallet conveyor line 74 and below the stacking space.

[0017] The material conveyor line 2 includes a material rack 24, a material drive motor 21, a material transmission component, and material rotating rollers 23. Several material rotating rollers 23 are rotatably mounted on the material rack 24. The material drive motor 21 is connected to the material rotating rollers 23 via the material transmission component. The material rack 24 primarily bears the weight of the material drive motor 21 and the material rotating rollers 23. Since several material rotating rollers 23 are rotatably mounted on the material rack 24, simply connecting the material drive motor 21 to the material rotating rollers 23 via a material transmission component such as a chain or sprocket will cause the material rotating rollers 23 to rotate actively, thereby moving the material from the material conveyor line 2. Furthermore, the material conveyor line 2 is existing technology and will not be described in detail here.

[0018] The material includes a barrel body 3, which is provided with a snap-fit ​​groove 31. The snap-fit ​​groove 31 is matched with the stacking barrel working position 14211. The snap-fit ​​groove 31 provides a clamping position for the barrel body 3. The matching of the snap-fit ​​groove 31 with the stacking barrel working position 14211 ensures that the stacking barrel working position 14211 can stably clamp the barrel body 3, and prevents unstable clamping due to the cylindrical structure of the barrel body 3.

[0019] The top of the barrel 3 is provided with a docking groove from top to bottom. The inner wall of the docking groove matches the outer wall of the bottom of the barrel 3, so that when the two barrels 3 are stacked, the bottom of the upper barrel 3 can be accommodated in the docking groove, so that the two barrels 3 will not move relative to each other in the horizontal direction.

[0020] like Figure 1 As shown, X is the direction in which material conveyor line 2 conveys objects, and the objects flow into the first frame from the X direction.

[0021] like Figure 1 , 2 As shown in Figure 4, the lifting stacking drum assembly 11 includes a lifting drive motor 111 and a lifting drive plate 116. The lifting drive motor 111 is located on the top of the frame 1. Lifting rotating seats 112 are provided on both sides of the top of the frame 1. A lifting rotating shaft 113 is rotatably arranged between the two lifting rotating seats 112. A lifting main rotating gear 1131 is provided on the lifting rotating shaft 113. A lifting driven rotating gear 115 is provided at the bottom of the frame 1. The lifting main rotating gear 1131 and the lifting driven rotating gear 115 are connected by a lifting rotating chain 114. The lifting rotating chain 114 is connected to the lifting drive plate 116 through a lifting connector. Two lifting drive top plates 117 are also provided on the lifting drive plate 116. The two lifting drive top plates 117 are located on both sides of a material rotating roller 23.

[0022] The frame 1 is also equipped with a lifting guide rail 118, and a lifting slider is provided on the lifting drive plate 116 corresponding to the lifting guide rail 118. The lifting guide rail 118 and the lifting slider are slidably connected. The lifting drive motor 111 can drive the lifting rotating chain 114 to rotate between the lifting driven gear 115 and the lifting main rotating gear 1131. Since the lifting rotating chain 114 is connected to the lifting drive plate 116 through the lifting connector, and the lifting guide rail 118 is slidably connected to the lifting slider, the lifting drive plate 116 can be driven to move along the lifting guide rail 118 during the rotation of the lifting rotating chain 114, which in turn drives the lifting drive top plate 117 to move along the lifting guide rail 118, and in turn drives the barrel 3 to move along the lifting guide rail 118.

[0023] like Figures 1-2As shown, material blocking components 12 are installed at both ends on the feeding side. Each material blocking component 12 includes a material mounting base 121, which is connected to the material rack 24. A material blocking cylinder 122 is installed on the material mounting base 121, and a material blocking plate 123 is installed on the output shaft of the material blocking cylinder 122. The material mounting base 121 is securely connected to the material rack 24, providing a reliable mounting base for the material blocking cylinder 122. When the material is conveyed to the corresponding position of the positioning component 13, the material blocking cylinder 122 drives the material blocking plate 123 to move. The simultaneous blocking at both ends can form symmetrical limits from both sides of the material, avoiding material deviation or tipping caused by single-end blocking, and accurately preventing subsequent material from entering the frame 1 and interfering with the positioning and lifting operation of the current material.

[0024] The output shafts of the two material blocking cylinders 122 extend in opposite directions. This opposite-extending design allows the material blocking plates 123 on both sides to move closer together from the lateral sides of the barrel 3, forming a symmetrical block, rather than a simple block from one end. This avoids the risk of the barrel 3 shifting or tipping over that may be caused by single-end or unidirectional blocking.

[0025] like Figure 1 , 5 As shown in Figure 6, the stacking drum support assembly 14 includes a stacking drum support plate 141. A stacking drum moving assembly is provided on the stacking drum support plate 141. The stacking drum moving assembly includes a stacking drum drive motor 143 and a stacking drum connecting seat 147. The two stacking drum connecting seats 147 are respectively connected to the two ends of one side of the stacking drum support plate 141. A stacking drum connecting shaft 144 is rotatably arranged between the two stacking drum connecting seats 147. The stacking drum drive motor 143 is connected to the stacking drum connecting shaft 144. Stacking drum rotating wheels 145 are provided at both ends of the other side of the stacking drum support plate 141. The stacking drum rotating wheels 145 are respectively connected to the stacking drum connecting shaft 144 through a stacking drum connecting belt 146.

[0026] The stacking drum moving assembly also includes stacking drum moving plates 142. One stacking drum moving plate 142 is connected to one side of the stacking drum connecting belts 146 on both sides at both ends, and the other stacking drum moving plate 142 is connected to the other side of the stacking drum connecting belts 146 on both sides at both ends. The two stacking drum connecting plates are arranged facing each other, and stacking drum connecting grooves are provided on the stacking drum connecting plates. The stacking drum connecting grooves on the two stacking drum connecting plates form a stacking drum working position 14211. A locking part 1421 is provided on the inner wall of the stacking drum working position to better clamp the drum.

[0027] The bottom of the stacking drum support plate 141 is also provided with a stacking drum guide rail. The stacking drum moving plate 142 is provided with a stacking drum slider at the corresponding position of the stacking drum guide rail, and the stacking drum slider is slidably connected to the stacking drum guide rail. The stacking drum support plate 141 is fixedly connected to the frame 1. The frame 1 provides support for the stacking drum support plate 141 and the stacking drum moving assembly. A stacking drum connecting shaft 144 is rotatably connected between the two stacking drum connecting seats 147. The stacking drum drive motor 143 is connected to the stacking drum connecting shaft 144. The stacking drum drive motor 143 can drive the stacking drum connecting shaft 144 to rotate. Since the stacking drum rotating wheels 145 are respectively connected to the stacking drum connecting shaft 144 through the stacking drum connecting belts 146, there are two stacking drum connecting belts 146 rotatably connected to one stacking drum rotating shaft.

[0028] One stacking drum moving plate 142 has its two ends connected to one side of the two stacking drum connecting belts 146, and the other stacking drum moving plate 142 has its two ends connected to the other side of the two stacking drum connecting belts 146. Therefore, when the stacking drum drive motor 143 drives the stacking drum rotating shaft to rotate, and the stacking drum rotating shaft drives the stacking drum connecting belts 146 to rotate, the two stacking drum moving plates 142 can move closer to each other or further away from each other.

[0029] The stacking slider and the stacking moving plate 142 are slidably connected, so that the two stacking moving plates 142 move closer to each other or further away from each other along the stacking guide rail.

[0030] like Figures 7-8 As shown, the positioning assembly 13 includes a positioning mounting plate 139, which is fixedly connected to the frame 1. The positioning mounting plate 139 is provided with a positioning drive motor 131 and a positioning connecting plate. A positioning drive wheel 132 is rotatably provided on one side of the bottom of the positioning connecting plate, and a positioning driven wheel 133 is rotatably provided on the other side of the bottom of the positioning connecting plate. The positioning drive wheel 132 is connected to the positioning drive motor 131, and the positioning drive wheel 132 is connected to the positioning transmission wheel through a positioning belt 134.

[0031] The positioning assembly 13 also includes a positioning moving plate 136. One positioning moving plate 136 is connected to one side of the positioning belt 134 via a positioning moving buckle 135, and the other positioning moving plate 136 is connected to the other side of the positioning belt 134 via a positioning moving buckle 135. Positioning clamping plates 137 are provided on both sides above the positioning moving plate 136. The positioning clamping plates 137 extend between the two material rotating rollers 23. A positioning guide rail 138 is provided at the corresponding position of the positioning moving plate 136 on the material rack 24. A positioning slider 1361 is provided at the corresponding position of the positioning moving plate 136 on the positioning guide rail 138. The positioning slider 1361 is slidably connected to the positioning guide rail 138. The positioning mounting plate 139 is fixedly connected to the frame 1, and the frame 1 provides support for the positioning component 13. One positioning moving plate 136 is connected to one side of the positioning belt 134 through the positioning moving buckle 135, and the other positioning moving plate 136 is connected to the other side of the positioning belt 134 through the positioning moving buckle 135. The positioning slider 1361 is slidably connected to the positioning guide rail 138, that is, when the positioning belt 134 rotates, it can drive the two positioning moving plates 136 to move closer to each other or further away from each other along the positioning guide rail 138. Positioning plates 137 are provided on both sides above the positioning moving plate 136. There are two positioning plates 137 on one positioning moving plate 136, and two positioning moving plates 136 have four positioning plates 137. The four positioning plates 137 are arranged around the bottom of the barrel 3, and the positioning plates 137 extend out between the two material rotating rollers 23, that is, the positioning plates 137 pass through the gap between the two material rotating rollers 23.

[0032] The positioning plate 137 is also provided with a positioning groove, which is matched with the outer side wall of the bottom of the barrel 3.

[0033] The positioning groove matches the outer wall of the bottom of the barrel 3, and can partially match the arc surface of the bottom of the barrel 3, limiting the barrel 3 from all sides and effectively preventing the barrel 3 from shifting laterally during the positioning process.

[0034] like Figure 9 , Figure 10 , Figure 15 and Figure 17As shown, the stacker conveyor includes a second frame 01, on which a material stack transfer line 03 and a material stack conveying line 02 are installed. The material stack conveying line 02 and the material stack transfer line 03 are arranged sequentially in the conveying direction. A stacking space 04 is located on one side of the second frame 01, below the material stack transfer line 03 and the material stack conveying line 02. A pallet conveying line 74 is installed on the second frame 01 below the stacking space 04. Here, "below" refers to directly below and to the side below. One end of the pallet conveying line 74 extends out of the second frame 01. A movable pusher assembly 5 is installed on the second frame 01 to push material stacks 82 into the stacking space 04. A first baffle assembly 6 is provided on one side of the stacking space opposite to the movable pusher assembly 5. A second baffle assembly 60 and a limiting pusher assembly 4 are respectively provided on the second frame 01 on the opposite side of the stacking space. The second baffle assembly 60 is perpendicular to the first baffle assembly 6, and the limiting pusher assembly 4 is perpendicular to the first baffle assembly 6. A movable bearing assembly 7 is provided above the pallet conveyor line 74. The movable bearing assembly 7 includes a bearing drive assembly and a bearing plate 71 slidably disposed on the pallet conveyor line. The bearing drive assembly drives the bearing plate 71 to move. A lifting bearing assembly 73 that can pass through the pallet conveyor line is provided on the pallet conveyor line 74 and below the stacking space.

[0035] The material stack conveyor line 02 is used to receive a single material stack 81 that has been stacked and formed. When several material stacks 81 are formed into a material stack group 82 on the material stack conveyor line 02, they are conveyed to the material stack group transfer line 03. At this time, the bearing drive component in the moving bearing component 7 drives the bearing plate 71 to slide to the bottom of the stacking space 04.

[0036] Subsequently, the movable pusher assembly 5 moves horizontally towards the stacking space 04, pushing the material stack 82 on the material stack transfer line 03 onto the support plate 71. During the process of pushing the material stack 82 onto the support plate 71, it will also pass through a set of rolling rollers before reaching the support plate 71. During the pushing process, the first baffle assembly 6, the second baffle assembly 60, and the limiting pusher assembly 4 first reach the preset position. The first baffle assembly 6, the second baffle assembly 60, the movable pusher assembly 5, and the limiting pusher assembly 4 correspond to the four sides of the square, and together enclose to form the stacking space 04 with an adjustable size, which limits and constrains the stack 83 formed by the material stack 82 to prevent the material stack 82 from shifting or scattering. While waiting for the number of material stacks 82 to reach the preset quantity, during the process of integrating them into stack group 83, the pallet conveyor line 74 transports the pallet to the underside of the support plate 71. The first baffle assembly 6, the second baffle assembly 60, the moving push plate assembly 5, and the limiting push plate assembly 4 clamp the stack group 83. Then, the support drive assembly drives the support plate 71 away from the underside of the stacking space. Then, the lifting support assembly 73 moves to lift the pallet upward, so that the pallet is disengaged from the pallet conveyor line 74 and supports the stack group 83. The clamping of the first baffle assembly 6, the second baffle assembly 60, the moving push plate assembly 5, and the limiting push plate assembly 4 on the stack group 83 is released. Then, the lifting support assembly 73 moves in the opposite direction, and the stack group 83 falls smoothly onto the pallet conveyor line after the pallet is displaced, so that the pallet re-contacts the pallet conveyor line 74. The pallet conveyor line 74 can then transport the pallet carrying the stack group 83 to the next process.

[0037] like Figures 10-12 As shown, the movable pusher assembly 5 includes a movable drive and a pusher assembly 55. The movable drive includes a movable drive motor 52, a movable transmission shaft 53, a movable driven shaft, a movable drive wheel 51, a movable driven wheel, and a movable transmission belt 54. The movable drive motor 52 is mounted on the second frame. One end of the crossbeam 511 at the top of the second frame is rotatably mounted on the movable transmission shaft 53 via a bearing seat and bearing. The other end of the crossbeam at the top of the second frame is rotatably mounted on the movable driven shaft via a bearing seat and bearing. The movable drive wheel 51 is mounted on the movable transmission shaft 53, and the movable driven wheel is mounted on the movable driven shaft. The movable transmission belt 54 is sleeved between the movable drive wheel and the movable driven wheel. The output shaft of the movable drive motor 52 is connected to the movable transmission shaft 53, and the movable transmission belt 54 is connected to the pusher assembly 55. This structure allows the movable drive motor 52 to drive the movable transmission belt 54 to move, and the pusher assembly 55 is connected to the movable transmission belt 54, enabling the movable drive motor 52 to drive the movable pusher assembly 55 to move.

[0038] The push plate assembly 55 includes a push plate frame 56, a push plate top plate 561, and a push plate guide plate 551. The push plate guide plate 551 is connected to the top two sides of the push plate frame 56 respectively. Push plate guide wheels 5511 are provided on the outer side of the push plate guide plate 551. A third gap 55111 is provided between two adjacent push plate guide wheels 5511 along the width direction of the push plate guide plate 551. The crossbeam 511 is provided with a sliding groove, and the push plate guide wheels 5511 are located in the sliding groove.

[0039] The push plate frame 56 is equipped with several push plate top plates 561. Except for the bottommost push plate top plate, the other push plate top plates 561 are equipped with top plate guide sleeves 5611. The top plate guide sleeves 5611 are internally threaded with top plate screws 5612, which are connected to top plate handles 5613. The push plate frame 56 is also equipped with push plate guide rails. Except for the bottommost push plate top plate, the other push plate top plates 561 have top plate sliders positioned corresponding to the push plate guide rails. The push plate guide wheels 5511 on the push plate guide plate 551 match the moving slide grooves. The limiting effect of the push plate guide wheels 5511 ensures that the push plate assembly 55 always slides along a preset path during movement, preventing deviation. The push plate top plate 561 slides against the push plate guide rail on the push plate frame 56 via a top plate slider. Combined with the threaded transmission structure of the top plate screw 5612 and the top plate guide sleeve 5611, the operator can precisely adjust the height position of the push plate top plate 561 by rotating the top plate handle 5613. This allows the push plate assembly 55 to adapt to material stacks of different heights, avoiding problems such as unstable pushing and stack breakage caused by differences in the height of the material stacks, and improving the equipment's compatibility with diverse materials.

[0040] The pusher frame 56 and the pusher guide plate 551 form an integrated support structure. The setting of several pusher top plates 561 can realize the uniform pushing of material stacks at multiple points, avoiding the stacks from tipping over or deforming due to single-point force.

[0041] like Figure 10 , Figures 13-14 As shown, the limiting push plate assembly 4 includes a limiting plate 41, a limiting lateral adjustment assembly, and a limiting longitudinal adjustment assembly. The limiting lateral assembly includes a limiting lateral plate 46, a limiting lateral rotation shaft 47, and a limiting lateral main rotation gear. A limiting lateral slider 44 is provided on the second frame 01. A limiting lateral guide rail 461 is provided on the lower side of the limiting lateral plate 46, and the limiting lateral guide rail 461 is connected to the limiting lateral slider 44. A limiting lateral rack 462 is provided on the upper side of the limiting lateral plate 46, and the limiting lateral rack 462 is connected to the limiting lateral rotation wheel on the limiting lateral rotation shaft 47. The limiting lateral rotation shaft 47 is also provided with a limiting lateral driven rotation gear 48, which meshes with the limiting lateral main rotation gear through a limiting lateral chain. The limiting lateral main rotation gear is connected to the limiting lateral handle 45.

[0042] The longitudinal adjustment component includes a longitudinal fixing plate 40 and a longitudinal drive motor 42. The longitudinal fixing plate 40 is mounted on a transverse limiting plate, and the longitudinal drive motor 42 is mounted on the longitudinal fixing plate 40. The limiting plate 41 is also provided with a limiting rack 411, which meshes with a longitudinal limiting gear on the output shaft of the longitudinal drive motor 42. Limiting guide rails 412 are provided on both sides of the limiting rack 411, and limiting sliders 43 are provided on the limiting plate 41 at positions corresponding to the limiting guide rails 412. The limiting guide rails 412 and the limiting sliders 43 are slidably connected. The longitudinal limiting gear on the output shaft of the longitudinal drive motor 42 meshes with the limiting rack 411 on the limiting plate 41, and combined with the sliding guidance of the limiting guide rails 412 and the limiting sliders 43, the automatic lifting and lowering adjustment of the limiting plate 41 can be realized. The limit height can be adjusted according to the stacking height of the material stack to ensure full height constraint of the stack and prevent the upper layer of material from tipping over. In the pallet dropping process of the stack, the limit plate 41 can be quickly lifted by the limit longitudinal drive motor 42 to release the lateral limit and make way for the pallet conveying, without the need for manual operation, thus improving the degree of automation of the operation.

[0043] The operator can rotate the handle to drive the limit plate 46 along the limit slider 44 and the transverse guide rail on the second frame 01 through the meshing transmission of the gear chain, thereby achieving precise adjustment of the transverse position of the limit plate 41. It can flexibly adjust the limit spacing according to the width specifications of the material stack, avoiding stack offset due to excessive spacing or scratches due to insufficient spacing.

[0044] The first baffle assembly and the second baffle assembly have the same structure, only their positions are different, such as... Figure 15 and Figure 16As shown, the second baffle assembly 60 includes an adjusting push frame 61, an adjusting push rod 62, and an adjusting movable plate 63. The adjusting push frame 61 is connected to the second frame 01. A first guide rail 610 is provided on the inner side of the lower end of the adjusting push frame 61, and a first sliding groove is provided on the first guide rail 610. The adjusting movable plate 63 is connected to the adjusting push frame 61 through the adjusting push rod 62. The adjusting push frame 61 is also provided with a first adjusting plate 65, a second adjusting plate 66, and an adjusting rotating shaft 64. An adjusting slider 651 is provided on the first adjusting plate 65, and an adjusting guide is provided on the lower side of the second adjusting plate 66. The second adjusting plate 66 has a guide rail 661, and the adjusting slider 651 is slidably connected to the adjusting guide rail 661. The inner side of the second adjusting plate 66 is provided with a second guide rail 660, and the second guide rail 660 is provided with a second sliding groove. The adjusting rotating shaft 64 is rotatably mounted on the adjusting push frame 61. An adjusting motor is mounted on the adjusting push frame 61, and the output shaft of the adjusting motor is connected to the adjusting rotating shaft 64. An adjusting rotating gear 641 is provided on the adjusting rotating shaft 64. An adjusting rack 662 is provided on the upper side of the second adjusting plate 66, and the adjusting rack 662 is meshed with the adjusting rotating gear 641. The adjusting push rod 62 includes a first adjusting push rod and a second adjusting push rod; the upper end of the first adjusting push rod is connected to a first shaft 1a, which is hinged to the adjusting push frame 61; the lower end of the first adjusting push rod is connected to a second shaft 2a, and the two ends of the second shaft 2a are respectively provided with first rollers, which are slidably disposed in a second slide groove; the second shaft 2a is hinged to the adjusting moving plate 63; the upper end of the second adjusting push rod is provided with a third shaft, which is hinged to the adjusting moving plate 63; the lower end of the second adjusting push rod is provided with a fourth shaft 4a, and the two ends of the fourth shaft are respectively provided with second rollers, which are slidably disposed in a first slide groove; the middle parts of the first adjusting push rod and the second adjusting push rod are hinged together by a fifth shaft 5a. By adjusting the motor to rotate the adjusting shaft 64, the adjusting shaft 64 can drive the adjusting gear 641 to rotate. Through the meshing transmission between the adjusting gear 641 and the adjusting rack 662 on the second adjusting plate 66, the second adjusting plate 66 is driven to slide along the adjusting guide rail 661 of the first adjusting plate 65, which can drive the first adjusting push rod and the second adjusting push rod to swing, thereby realizing the horizontal position movement of the adjusting moving plate 63. like Figures 17-18As shown, the pallet conveyor line 74 includes a second pallet conveyor frame 740, a pallet drive motor 741, a pallet drive drive sprocket 742, a pallet drive driven sprocket 743, a pallet drive chain, and two or more pallet conveying rollers 744. One end of the second pallet conveyor frame 740 is provided with a pallet placement space. The pallet drive motor 741 is mounted on the second pallet conveyor frame 740. The pallet drive drive sprocket 742 is mounted on the output shaft of the pallet drive motor 741. At least one end of the pallet conveying roller 744 is provided with a pallet drive driven sprocket. The pallet drive chain is sleeved on the pallet drive drive sprocket and the pallet drive driven sprocket. The pallet conveying roller is rotatably mounted at the other end of the second pallet conveyor frame. In this structure, when the pallet drive motor 741 is working, it drives the pallet drive drive sprocket 742 to rotate, which in turn drives the pallet drive chain to move, thereby driving the pallet conveying roller to rotate, so as to achieve the purpose of conveying the pallet; at the same time, the pallet placement space is convenient for placing the pallet.

[0045] like Figures 17-18 As shown, the movable carrier assembly 7 includes a carrier drive assembly and a carrier plate 71 slidably disposed on the pallet conveyor line. The carrier drive assembly includes a carrier drive motor 72, a carrier transmission shaft 721, a carrier driven shaft, a carrier drive wheel 7211, a carrier driven wheel 7222, and a carrier chain 7223. The carrier drive motor 72 is disposed on the second frame or the pallet conveyor line and is connected to the carrier transmission shaft 721. Carrier driven shafts are disposed at both ends of the other end of the second pallet conveyor frame, and carrier driven wheels 7222 are disposed on the carrier driven shafts. The two carrier driven wheels 7222 are respectively connected to the carrier drive wheels 7211 at both ends of the carrier transmission shaft 721 via the carrier chain 7223. Rotating carrier pulleys 711 are disposed on both sides of the carrier plate 71, and the carrier pulleys 711 are supported by the second pallet conveyor frame 740. Connectors connected to the carrier chain 7223 are disposed on the carrier plate 71. When the load drive motor 72 is working, the load drive motor 72 drives the load transmission shaft 721 to rotate, thereby driving the load drive wheel 7211 to rotate, which in turn drives the load chain 7223 to move. The load chain drives the load plate 71 through the connecting parts, allowing the load pulley to move on the second frame 740 of the pallet conveyor, thereby changing the position of the load plate 71.

[0046] like Figures 17-20As shown, the lifting support assembly 73 includes a second lifting frame 731, a lifting drive, and a lifting frame 739. The second lifting frame 731 is mounted on a second frame or on a pallet conveyor line. The lifting drive includes a lifting cylinder 732, a first swing rod 733, a second swing rod 7330, a connecting rod 735, a lifting transmission shaft 734, and an eccentric mechanism. The cylinder body of the lifting cylinder 732 is hinged to the second lifting frame 731, and the piston rod of the lifting cylinder 732 is hinged to one end of the first swing rod 733. Lifting transmission shafts 734 are respectively provided at both ends of the second lifting frame 731. The second swing rod 7330 is fixed on the lifting transmission shaft 734, and the other end of the first swing rod 733 is fixed on one of the lifting transmission shafts. The connecting rod 735 is hinged between the two second swing rods. An eccentric mechanism is provided at both ends of the lifting transmission shaft, and the eccentric mechanism is in contact with the lifting frame 739.

[0047] The eccentric mechanism includes a drive block 7360, a drive shaft 7361, and a drive wheel 736. Drive blocks 7360 are connected to both ends of the lifting drive shaft, and the drive shaft 7361 is connected to the other end of the drive block 7360. The drive wheel 736 is connected to the drive shaft 7361, and its axis is offset from the axis of the lifting drive shaft. The drive wheel 736 contacts the lifting frame 739.

[0048] A lifting slide sleeve 737 is provided on the second lifting frame 731, and a lifting guide rod 738 is slidably provided inside the lifting slide sleeve 737. The lifting guide rod 738 is connected to the lifting frame 739.

[0049] In the above structure, the rotation of the drive wheel 736 causes the lifting frame 739 to move, and the lifting frame 739 moves along the sliding direction of the lifting guide rod 738 and the lifting sleeve 737.

[0050] The lifting frame 739 is equipped with multiple lifting brackets 7391, with a first gap 73911 between adjacent lifting brackets 7391. The first gap 73911 is larger than the gap between the pallet conveying rollers, and the cross-sectional area of ​​the lifting bracket 7391 is smaller than the second gap between two adjacent pallet conveying rollers. The first gap 73911 being larger than the gap between the pallet conveying rollers and the cross-sectional area of ​​the lifting bracket 7391 being smaller than the second gap between two adjacent pallet conveying rollers allow the lifting moving plate 7391 to smoothly extend into the gap between the conveying rollers. This not only accurately lifts the pallet to complete the lifting action but also does not obstruct the normal operation of the pallet conveying rollers. It also provides reliable structural support for the smooth transfer of the pallet, improving the efficiency and safety of the overall conveying and lifting operation.

[0051] In the above structure, when the lifting cylinder is working, it drives the first swing arm to swing, which in turn drives one of the lifting drive shafts to rotate. Under the action of the connecting rod and the second swing arm, it drives the other lifting drive shaft to rotate, which in turn drives the drive block to swing. The drive block drives the drive wheel to swing through the drive shaft, which in turn drives the lifting frame to rise. When the drive wheel swings, the lifting frame descends due to its own gravity, thus allowing the lifting support to rise and fall.

[0052] like Figures 22-23 As shown, the pallet destacking machine 9 includes a pallet destacking frame 92. A destacking conveyor line 91 is provided at the bottom of the pallet destacking frame 92 and is connected to the pallet conveyor line. A destacking drive motor 93 is provided at the top of the pallet destacking frame 92 and is connected to a destacking rotating shaft 94. Both sides of the destacking rotating shaft 94 are connected to destacking chains 941. The destacking chains 941 are connected to a destacking moving plate 95. A destacking guide wheel 951 is provided on the destacking moving plate 95 and is slidably connected to the pallet destacking frame 92.

[0053] On the destacking moving plate 95, destacking cylinders 952 are arranged on both sides facing each other. The output shaft of the destacking cylinder 952 is connected to the destacking clamping plate 953. Destacking abutment plates 954 are arranged at intervals on the destacking clamping plate 953. The destacking abutment plates 954 are matched with the clamping position of the pallet. Pallets are stacked from bottom to top inside the destacking moving plate 95. Then, the destacking cylinder 952 drives the destacking clamping plates 953 to move closer together, which in turn drives the destacking abutment plate 954 to clamp the bottom pallet. When the pallet needs to be placed on the destacking conveyor line 91, the destacking drive motor 93 drives the destacking moving plate 95 to move onto the destacking conveyor line 91. During the movement, the destacking guide wheel 951 slides on the pallet destacking frame 92, so that the destacking moving plate 95 can move vertically on the pallet destacking frame 92. Before placing it on the destacking conveyor line 91, the destacking conveyor line 91 stops running, and the destacking cylinder 952 drives the destacking clamping plates 953 to move away from each other, so that the bottom pallet falls onto the destacking conveyor line 91.

[0054] Then the destacking drive motor 93 drives the destacking moving plate 95 to move upward, clamping the second pallet from bottom to top. Then the destacking drive motor 93 continues to drive the destacking moving plate 95 to move upward, so that the second pallet from bottom to top moves away from the first pallet from bottom to top. The destacking conveyor line 91 operates and drives the pallet to be transported to the pallet conveyor line. When the next pallet is to be placed, this cycle is repeated.

[0055] The working principle of this invention is as follows: The material conveying line 2 is mainly used to convey materials. When the material, such as the barrel 3, reaches the corresponding position, the material blocking component 12 will operate, mainly to prevent the material on the material conveying line 2 from entering the machine frame 1. Then, the positioning component 13 will position the material. The lifting stacking component 11 will convey the material from bottom to top to the stacking working position 14211. The stacking working position 14211 will catch the material. The lifting stacking component 11, the positioning component 13 and the material blocking component 12 will reset, and then wait for the arrival of the next material.

[0056] When another material arrives, the above operation is repeated. Specifically, when another material reaches the corresponding position, the material blocking component 12 will operate, primarily preventing material from the material conveyor line 2 from entering the frame 1. Then, the positioning component 13 will position the material, and the lifting stacking component 11 will convey the material from bottom to top. During the lifting stacking component 11's process of lifting the material, the top of the lifted material first contacts the bottom of the material at the stacking workstation 14211. Then, the stacking workstation 14211 releases, no longer clamping the material. At this point, the material that was originally stacked... A material on the bucket working position 14211 will fall onto the material on the lifting and stacking bucket assembly 11. At this time, the lifting and stacking bucket assembly 11 provides support for the two materials. Then, the lifting and stacking bucket assembly 11 continues to move downward. When the material below the lifting and stacking bucket assembly 11 reaches the corresponding position of the stacking bucket working position 14211, the stacking bucket working position 14211 clamps the material. At this time, the stacking bucket working position 14211 provides support for the two materials. The lifting and stacking bucket assembly 11, the positioning assembly 13 and the material blocking assembly 12 are reset, and then wait for the arrival of the next material.

[0057] When another material arrives, that is, when another material reaches the corresponding position, the material blocking component 12 will operate, mainly to prevent the material on the material conveyor line 2 from entering the frame 1. Then the positioning component 13 will position the material. The lifting stacking component 11 will convey the material from bottom to top. At this time, during the process of lifting the material by the lifting stacking component 11, the top of the lifted material will first contact the bottom of the material on the stacking work position 14211. Then the stacking work position 14211 will release and no longer clamp the material. At this time, the two materials that were originally on the stacking work position 14211 will fall on the material on the lifting stacking component 11. At this time, the lifting stacking component 11 provides support for the three materials. Then the lifting stacking component 11 moves downward and places the three materials on the material conveyor line 2 to complete the stacking of the three materials. Furthermore, since the stacking support assembly 14 includes one or more stacking work positions 14211, and the positioning assembly 13 and the lifting stacking assembly 11 are arranged corresponding to the stacking work positions 14211, the number of materials stacked each time can be more than one.

[0058] Three material stacks form a material pile, which is then transported to the material pile conveyor line 02 via material conveyor line 2. The material pile conveyor line 02 sequentially transports several material piles to the material pile group transfer line 03. Then, the bearing drive assembly moves the bearing plate below the stacking space. Next, the moving push plate assembly moves horizontally into the stacking space, pushing the material pile groups on the material pile group transfer line one by one onto the bearing plate. During the pushing process, the first baffle assembly, the second baffle assembly, and the limiting push plate assembly first reach the preset position, blocking the stacking space in three directions to prevent the material pile groups entering the stacking space from tipping over, shifting, or scattering. When the number of material stacks reaches a preset quantity, a stack is formed. Simultaneously, the pallet is transported to the underside of the support plate via the pallet conveyor line. Alternatively, the pallet can be transported to the underside of the support plate at the beginning, and then the stack is clamped by the moving push plate assembly and the first baffle assembly. The support drive assembly moves the support plate away from the stacking space, and then the lifting support assembly moves upward to lift the pallet, causing the pallet to disengage from the pallet conveyor line. The pallet then carries the stack. After releasing the clamping of the stack by the moving push plate assembly and the first baffle assembly, the lifting support assembly moves in the opposite direction to move the pallet carrying the stack downward, causing the pallet to re-engage with the pallet conveyor line. The pallet conveyor line can then transport the pallet carrying the stack to the next process. Therefore, in this invention, the stacking assembly is first formed on the support plate. The stacking assembly does not directly contact the pallet. After the stacking assembly is formed, the support plate is removed, and the pallet supports the stacking assembly under the action of the lifting support component. Then the stacking assembly is transported out through the pallet. Therefore, the stacking assembly of this invention falls directly onto the pallet as a whole, without excessive friction with the pallet, which would make the pallet easily damaged, and also reduces the wear of the stacking assembly.
