Description

Technical Field

[0001] This invention relates to the field of industrial logistics automation equipment technology, and in particular to a stacker receiving machine and a stacking system. Background Technology

[0002] For many long, narrow materials, such as aluminum profiles, spacers are needed to provide multi-point support during production and transportation to prevent bending and deformation. During material stacking, multiple layers are separated and stacked using spacers, facilitating the formation of stacks and transportation.

[0003] Taking the invention patent "A Novel Automatic Stacking System for Aluminum Profiles" with patent number CN207511452U as an example, the stacking equipment in the prior art uses a lifting bracket to lift and transfer multiple spacers supporting the material. The bracket supports both ends of the spacers and lowers them so that they are stacked in the material frame.

[0004] During stacking, after the spacers are placed on top of the stacked material, they need to be moved downwards to separate from the spacers and then staggered back to allow for the next layer of material to be stacked. Because the spacers deform over time, there are height discrepancies at the ends of each spacer, requiring ample space for the support bracket to retract. For thinner materials, the spacing between the spacers in the upper and lower layers is limited, and the support bracket may either not retract properly, easily pulling on the spacers during repositioning, or it may press down on the spacers of the lower layer during retraction. Both of these situations can easily lead to stack collapse, causing significant losses. Summary of the Invention

[0005] The purpose of this invention is to provide a stacking receiving machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0007] A stacking receiving machine includes: a base frame, with lifting components on both the left and right sides of the base frame; each lifting component includes multiple lifting columns arranged in a front-to-back direction, with the lifting columns of two lifting components corresponding to each other and aligned left and right; the base frame is provided with a lifting drive mechanism for driving the lifting components to move up and down; the upper end of each lifting column is provided with a support member, the support member having a support portion, and the support member is slidably connected to the lifting column in a vertical direction.

[0008] The stacking and receiving machine provided by this invention has at least the following beneficial effects: the lifting columns of the two lifting components correspond one-to-one, and the two paired support parts can support the left and right ends of the spacers. The lifting drive mechanism can drive the lifting components to move up and down, thereby enabling the spacers to move up and down in batches to realize the material receiving and placement action. After placement, the support parts need to continue to retract, so that all support parts are separated from the ends of the spacers they support. The support parts are slidably arranged in the vertical direction, which can increase the downward fault tolerance distance of the lifting components. The stacking and receiving machine of this invention, through the support parts that slide vertically, avoids the situation where the lower layer spacers are overturned when the lifting components release and retract material, thereby adapting to the close stacking of thin materials.

[0009] As a further improvement to the above technical solution, the lifting column is slidably connected to the base frame in the vertical direction. The lifting column has lifting teeth extending in the vertical direction. The lifting drive mechanism includes a drive gear and a lifting drive unit. The drive gear meshes with the lifting teeth, and the lifting drive unit is drivenly connected to the drive gear. Through the above technical solution, the lifting drive unit can drive the drive gear to rotate, thereby causing the lifting column to move up and down through gear meshing. Gear and rack transmission has advantages such as long service life, smooth operation, high reliability, and large power transmission, making it very suitable for the drive transmission application of the lifting column. Driving the linear motion of the lifting column through gear and rack transmission makes the vertical movement of the lifting column fast and accurate.

[0010] As a further improvement to the above technical solution, the lifting column includes a column body and a rotating component. The lifting gear is disposed on the column body, and the rotating component is rotatably disposed at the upper end of the column body. The supporting component is slidably connected to the rotating component in an upward and downward motion. The lifting column is provided with a rotary drive component for driving the rotating component to swing. Through the above technical solution, the rotary drive component can drive the rotating component to rotate relative to the column body, thereby enabling the supporting component to rotate and swing without affecting the up and down movement of the lifting column.

[0011] As a further improvement to the above technical solution, the lifting assembly also includes a transmission component, which is connected to the plurality of rotating parts to drive them synchronously, thereby enabling the supporting parts of the plurality of supporting components to rotate synchronously. Through this technical solution, the plurality of rotating parts are synchronously connected via the transmission component, allowing them to rotate synchronously while saving the cost of the rotation drive component.

[0012] As a further improvement to the above technical solution, the drive gears are configured in a one-to-one correspondence with the lifting columns, and the lifting drive mechanism includes a transmission shaft coaxially and fixedly connected to multiple drive gears. Through this technical solution, the transmission shaft can synchronously drive multiple drive gears to rotate, causing multiple lifting columns to move up and down synchronously.

[0013] As a further improvement to the above technical solution, the base frame is provided with multiple connecting sleeves, and the lifting column slides through the connecting sleeves one by one in the vertical direction. Through this technical solution, the lifting column can be connected to the base frame by sliding vertically through the connecting sleeves.

[0014] As a further improvement to the above technical solution, the connecting sleeve is rotatably connected to the base frame, the rotation axis of the connecting sleeve extends in the vertical direction, and the base frame is provided with a rotational driving component for driving the connecting sleeve to rotate. Through the above technical solution, the rotational driving component can drive the connecting sleeve to move relative to the base frame.

[0015] As a further improvement to the above technical solution, the lifting drive mechanism includes a lifting frame and a lifting drive unit. The lifting drive unit is used to drive the lifting frame to move up and down relative to the base frame. The lifting frame has multiple mutually flush lifting sections, and the lower end of the lifting column is rotatably connected to the lifting section. Through the above technical solution, the lifting drive unit can drive the lifting frame to move up and down, thereby driving the lifting column to move up and down relative to the base frame through the lifting section.

[0016] As a further improvement to the above technical solution, the multiple connecting sleeves are interconnected and rotate synchronously. Through this technical solution, the interconnected and synchronously rotating connecting sleeves enable the multiple lifting columns to rotate synchronously.

[0017] The present invention also provides a stacking system, comprising: a receiving frame, a frame conveyor, and the aforementioned stacking receiving machine; the frame conveyor is disposed between the two lifting components, the frame conveyor is disposed on the upper side of the base frame, the upper end of the frame conveyor has a conveying surface for supporting and conveying the receiving frame in the front-back direction, and the receiving frame is placed on the conveying surface.

[0018] The stacking system provided by this invention has at least the following beneficial effects: In actual use, the two lifting components rise to their upper limit position, and the left and right ends of the multiple spacers arranged in front and behind are supported by the support parts at the upper ends of each of the lifting columns, realizing the material receiving action. Then, the lifting drive mechanism drives the two lifting components to move downward, so that the spacers and the material on them can be stacked on the receiving frame. After the support parts separate from the supported spacer ends, the rotation drive component actuates, causing the support parts to rotate, and the support parts of the left and right lifting components swing to the left and right sides respectively, away from the middle receiving frame. Afterward, the lifting components return to their original position to receive material again. This process is repeated to realize the material receiving and stacking. The receiving frame and the stack of material on it that have completed the material receiving and stacking are transported away by the frame conveyor, and another receiving frame is transported between the two lifting components for the receiving and stacking of the next frame of material.

[0030] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 6 Taking the stacking and receiving of aluminum profiles as an example, the stacking and receiving machine of the present invention is implemented as follows:

[0032] A stacker receiving machine includes: a base frame 10 and a lifting assembly 20.

[0033] There are two lifting components 20. The two lifting components 20 are respectively located at the left and right ends of the base frame 10. Each lifting component 20 includes multiple lifting columns 100. The multiple lifting columns 100 are arranged at intervals along the front-to-back direction. The lifting columns 100 of the two lifting components 20 are aligned left and right in a one-to-one correspondence.

[0034] The base frame 10 is provided with a lifting drive mechanism 300 for driving the lifting assembly 20 to move up and down. The lifting drive mechanism 300 has a lifting drive end that is connected to the lifting column 100 and causes the lifting column 100 to move up and down relative to the base frame 10.

[0035] The upper end of the lifting column 100 is provided with a support member 200, which has a support portion 210 for supporting the partition bar. The support member 200 is slidably connected to the lifting column 100 in the vertical direction.

[0036] The supporting part 210 can support the ends of the spacers. In actual use, the supporting parts 210 of the two corresponding lifting columns 100 support the left and right ends of the spacers respectively. The multiple lifting columns 100 of the two lifting components 20 can support multiple spacers simultaneously, so that the materials on them can be placed stably. Then, driven by the lifting drive mechanism 300, the two lifting components 20 move downward, so that the spacers and aluminum profile materials can fall onto the material frame between the two lifting components 20.

[0037] After the spacer bars and materials fall onto the material frame, the support part 210, which has been withdrawn a sufficient distance, separates from the topmost spacer bar. At this time, if the aluminum profile material is thin and the distance between the upper and lower spacer bars is small, the lower end of the support member 200 contacts the end of the spacer bar below it. Since the support member 200 is slidably installed in the vertical direction, it will not move upward relative to the lifting column 100 under the action of the spacer bar ends, and will not cause excessive compression to the ends of the spacer bars, resulting in the spacer bars tipping over or the material stack collapsing.

[0038] like Figure 4 In the illustrated embodiment, the support member 200 has bushings 220 arranged in a vertical direction. The upper end of the lifting column 100 has two vertically extending guide posts 130. The two guide posts 130 are slidably inserted through the two bushings 220, so that the support member 200 and the lifting column 100 are connected by sliding up and down movement. The upper end of the guide post 130 has a limiting part 131.

[0039] The support member 200 can press down against the lifting column 100 under its own weight, and the same applies when supporting the partition bar. When the lifting assembly 20 moves down and the support member 200 contacts the partition bar below it, it can lift the support member 200 up and move it upward relative to the lifting column 100.

[0040] The sliding structure of the bushing 220 and guide post 130 can guide the upward and downward sliding movement with low sliding friction. In some other embodiments, the support 200 and the lifting column 100 can also be connected by a sliding groove or by other means such as a linear slide rail. The sliding groove connection has higher friction and often requires continuous lubrication. The connection structure of the linear slide rail is larger in volume.

[0041] After the spacer and material are placed in the material frame, the support part 210 needs to be reset upwards for the next material receiving. To avoid the end of the spacer blocking the support part 210, the support part 210 and the material frame need to move relative to each other. In some embodiments, the material frame and the material stack on it can be moved back and forth by a conveying device, so that the spacer and the support part 210 are staggered.

[0042] However, the weight of the material frame plus the material stack is relatively large, and frequent back-and-forth movement will lead to low stacking efficiency and high energy consumption. Therefore, the stacking receiving machine of the present invention achieves the mutual offset between the support part 210 and the end of the spacer by means of a rotatable and swingable support member 200. The main implementation method is as follows.

[0043] Example 1:

[0044] The lifting column 100 is slidably connected to the base frame 10 in the vertical direction. For example... Figures 2 to 3As shown, the lifting column 100 has lifting teeth 140 extending in the vertical direction. The lifting drive mechanism 300 includes a drive gear 310 and a lifting drive unit 320. The drive gear 310 is rotatably mounted on the base frame 10 and engages with the lifting teeth 140. The lifting drive unit 320 is drivenly connected to the drive gear 310. The lifting drive unit 320 can be a rotary drive element such as a servo motor, stepper motor, or pneumatic motor.

[0045] The number of drive gears 310 is the same as the number of lifting columns 100, and they are arranged in a one-to-one correspondence with each lifting column 100. The axis of the drive gear 310 is perpendicular to the vertical direction. In order to achieve synchronous lifting of multiple lifting columns 100 and reduce the number of lifting drive units 320 and save costs, multiple drive gears 310 are synchronously connected.

[0046] In this embodiment, the axial directions of the plurality of drive gears 310 are all arranged in the front-to-back direction. The lifting drive mechanism 300 also includes a transmission shaft 330 extending front-to-back, which is coaxially and fixedly connected to the plurality of drive gears 310. The lifting drive unit 320 is drivenly connected to the transmission shaft 330. The lifting drive unit 320 can synchronously drive the plurality of drive gears 310 to rotate via the transmission shaft 330, thereby causing the plurality of lifting columns 100 to move up and down synchronously.

[0047] In some other embodiments, the axial direction of the plurality of drive gears 310 is arranged in the left-right direction, and each drive gear 310 is coaxially fixedly provided with a driven shaft. The lifting drive mechanism 300 includes a drive shaft extending in the front-back direction. The drive shaft and the plurality of driven shafts can be synchronously connected by various transmission methods such as belt drive, chain drive, gear drive or worm gear drive.

[0048] In this embodiment, the lifting column 100 meshes with the drive gear 310, making it difficult to achieve relative rotation between the lifting column 100 and the drive gear 310. In this embodiment, the lifting column 100 includes a column body 110 and a rotating member 120. The column body 110 extends vertically, and the lifting gear 140 is located on the outer side of the column body 110. The rotating member 120 is rotatably mounted on the upper end of the column body 110. The support member 200 is slidably mounted on the upper side of the rotating member 120. The lifting column 100 is provided with a rotary drive member 400 for driving the rotating member 120 to swing.

[0049] like Figure 6In the illustrated embodiment, the lower end of the rotating member 120 is cylindrical and coaxially rotatably connected to the upper end of the column 110. Both the lower end of the rotating member 120 and the upper end of the column 110 have hollow inner cavities. The rotary drive component 400 includes a drive member 410 and a rotary drive unit 420. The inner cavities of the rotating member 120 and the column 110 are respectively the upper cavity and the lower cavity. The lower part of the drive member 410 is disposed in the lower cavity and is slidably connected to the lower cavity in the vertical direction. The rotary drive unit 420 is used to drive the drive member 410 to move up and down. The upper part of the drive member 410 is disposed in the upper cavity, and a cam groove structure inclined in the vertical direction is provided between the upper part of the drive member 410 and the rotating member 120.

[0050] Specifically, the upper outer periphery of the driving member 410 has a protruding cam driving end 411, and a driving groove 121 is provided on the inner wall of the upper cavity. The cam driving end 411 is slidably embedded in the driving groove 121. When the driving member 410 moves up and down relative to the rotating member 120, the cam driving end 411 moves along the driving groove 121, thereby driving the rotating member 120 to rotate relative to the column 110.

[0051] The rotary drive unit 420 can be selected as a pen-shaped cylinder arranged in the vertical direction. A return spring is also provided on the upper side of the drive member 410. The upper and lower ends of the return spring elastically abut against the top of the upper cavity and the upper end of the drive member 410, respectively, causing the drive member 410 to elastically press downwards. When the rotary drive unit 420 fails to drive, the drive member 410 can press downwards under the action of the return spring, keeping the support member 200 in its initial position and preventing material from loosening and falling.

[0052] In this embodiment, to reduce the space occupied at the upper end of the lifting column 100 and avoid obstructing material transfer or other equipment, the rotary drive component 400 is disposed within the cavity formed by the rotating component 120 and the column 110. The rotary drive component 400 is provided in a one-to-one correspondence with the lifting column 100.

[0053] The rotary drive component 400 can also be a micro servo motor, rotary cylinder, swing cylinder or other drive element. The rotary drive component 400 is set on the outside of the lifting column 100 and directly drives the rotating part 120 to rotate relative to the column 110. The structure is simpler and more direct and easier to maintain.

[0054] In a further embodiment, the lifting assembly 20 further includes a transmission component. The transmission component is connected to the plurality of rotating parts 120, causing the supporting parts 200 of the plurality of supporting components to rotate synchronously. The transmission component can employ various transmission methods such as belt drive, gear drive, or worm gear drive.

[0055] Example 2:

[0056] The base frame 10 is provided with a plurality of connecting sleeves 430. The lifting columns 100 are slidably inserted through the connecting sleeves 430 in a vertical direction. The connecting sleeves 430 are rotatably connected to the base frame 10. The axis of rotation of the connecting sleeves 430 extends in the vertical direction and is coaxially arranged with the lifting columns 100. The base frame 10 is provided with a rotary drive component 400 for driving the connecting sleeves 430 to rotate.

[0057] In this embodiment, the connecting sleeve 430 is disc-shaped, with a circular outer periphery and rotatably connected to the base frame 10. The connecting sleeve 430 has a through-hole in its center. The lifting column 100 slides through the through-hole. To ensure synchronous rotation of the connecting sleeve 430 and the lifting column 100, the through-hole in this embodiment is square, and the lifting column 100 is a square column.

[0058] The lifting drive mechanism 300 is located on the lower side of the base frame 10. (Refer to...) Figure 5 The lifting drive mechanism 300 includes a lifting frame 340 and a lifting drive unit. The lifting frame 340 is slidably connected to the base frame 10 in the vertical direction. The lifting drive unit is used to drive the lifting frame 340 to move vertically relative to the base frame 10. The upper end of the lifting frame 340 has multiple mutually flush lifting sections.

[0059] In this embodiment, the lower end of the lifting column 100 is rotatably connected to the lifting part, allowing the lifting column 100 to move up and down with the lifting frame 340 and to rotate under the action of the connecting sleeve 430. In other embodiments, the lower end of the lifting column 100 may elastically abut against the lifting part.

[0060] The rotary drive component 400 can drive the connecting sleeve 430 to rotate, so that the lifting column 100 can rotate relative to the base frame 10, thereby realizing the swing of the support part 210. The lifting drive unit can drive the lifting frame 340 to move up and down, thereby driving the lifting column 100 to move up and down relative to the connecting sleeve 430.

[0061] In this embodiment, the rotary drive component 400 includes a rotary drive motor and a transmission mechanism 440. The rotary drive motor is driven to connect to multiple connecting sleeves 430 via the transmission mechanism 440. The transmission mechanism 440 can be selected from various transmission structures such as belt drive, chain drive, gear drive, or worm gear drive. By driving the multiple connecting sleeves 430 to rotate through the rotary drive motor, the synchronous rotation of multiple lifting columns 100 is achieved.

[0062] It is worth noting that the support part 210 is eccentrically positioned with respect to the rotation axis of the lifting column 100, so that when the lifting column 100 rotates, the support part 210 can swing away from its original position.

[0063] The present invention also provides a stacking system, comprising: a receiving frame, a frame conveyor, and the stacking receiving machine.

[0064] The material frame conveyor is located on the upper side of the base frame 10, between the two lifting components 20. The upper end of the material frame conveyor has a conveying surface for supporting and conveying the receiving frame in the front-back direction. The receiving frame is placed on the conveying surface.

[0065] In actual use, the two lifting components 20 rise to their upper limit position, where the support parts 210 at the upper ends of each of the lifting columns 100 support the left and right ends of the multiple spacers arranged in front and behind, thus achieving the material receiving action. Then, the lifting drive mechanism 300 drives the two lifting components 20 to move downward, allowing the spacers and the material on them to be stacked on the receiving frame. After the support parts 210 separate from the supported spacer ends, the rotation drive component 400 actuates, causing the support parts 210 to rotate, and the support parts 210 of the left and right lifting components 20 swing to the left and right sides respectively, away from the middle receiving frame. Afterward, the lifting components 20 return to their original position to receive material again. This process is repeated to achieve material collection and stacking. The receiving frame and the stack of material on it that have completed collection and stacking are transported away by the frame conveyor, and another receiving frame is transported between the two lifting components 20 for the next frame of material to be received and stacked.
