Description

Technical Field

[0001] This invention relates to the technical field of shelf panel keel forming, and in particular to a supermarket shelf panel keel forming production line. Background Technology

[0002] Supermarket shelf panel keel forming refers to the process of cold-rolled steel plates being formed through a cold bending production line. The process is as follows: after the coil is uncoiled by the feeding machine, multiple sets of upper and lower leveling rollers level the plate to eliminate curling and internal stress. Fixed and movable stamping seats are set on one side of the frame. The stamping die is driven by a hydraulic cylinder to punch mounting holes, positioning holes, etc. on the plate to meet the assembly requirements of the shelf, beams, and support arms. Then the plate enters a multi-stage roll forming mechanism, where the upper and lower rollers roll it step by step, gradually bending the plate into a cross-sectional shape that integrates the shelf body, signage groove, and rear keel, achieving one-time forming of "shelf + keel". During the forming process, the corner cutting mechanism cuts the corners of the shelf, and then the follow-up cutting mechanism cuts it to a set length to obtain a single shelf profile. The cut shelf can directly enter welding, pickling, phosphating, electrostatic spraying, and drying processes to complete surface treatment and finished product assembly.

[0003] Chinese Patent CN110052845B discloses a shelf panel keel forming production line, characterized by comprising the following mechanisms: a leveling mechanism, a punching mechanism, a roll forming mechanism, a corner cutting mechanism, and a follow-up cutting mechanism; wherein, the leveling mechanism includes several sets of upper and lower leveling rollers, which are staggered and installed on a leveling table, and the sheet material to be formed passes through the gap between the upper and lower leveling rollers; the punching mechanism includes a fixed punching seat and a movable punching seat installed on one side of the frame, and a punching die is installed on the fixed punching seat and the movable punching seat via a hydraulic cylinder, and the movable punching seat is installed with the frame via a slide table; the beneficial effect of this invention is that this equipment can integrally form the shelf body and the signboard groove keel, thus eliminating the need to manufacture the two separately and weld them together later, simplifying the process while ensuring the product's load-bearing capacity.

[0004] In the aforementioned related technologies and existing technologies, when the material plates on the outer side of the material tray are finished, the original material tray needs to be unloaded and a new material tray needs to be installed before material feeding can begin. However, during the unloading, changing, and feeding process, there will be a long gap between the two material plates, which will affect the continuity of the subsequent production line processing. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a production line for forming supermarket shelf ribs.

[0006] The present invention provides a supermarket shelf rib forming production line, which adopts the following technical solution: including: The feeding assembly includes a support drive base and a dual feeding assembly. The dual feeding assembly is slidably mounted on the upper side of the support drive base. The support drive base drives the dual feeding assembly to move horizontally on the upper side of the support drive base. The dual feeding assembly is equipped with two material trays.

[0007] A double-layer conveyor belt assembly is provided, which is located on one side of the feeding assembly. The material plate passes through the double-layer conveyor belt assembly. Both sides of the double-layer conveyor belt assembly are provided with fast-following components. The fast-following components include clamping components and linear drive components. The linear drive components drive the clamping components to move while also driving the clamping components to clamp the material plate.

[0008] A flattening assembly is located on the side of the double-layer conveyor belt assembly away from the feeding assembly, and the material plate passes through the flattening assembly for flattening.

[0009] A roller-assisted conveying assembly is disposed on the side of the flattening assembly away from the double-layer conveyor belt assembly, and the roller-assisted conveying assembly provides auxiliary support for the material plate.

[0010] A punching assembly is located on the side of the roller auxiliary conveying assembly away from the flattening assembly. The roller auxiliary conveying assembly supports and feeds the material plate to the upper side of the punching assembly, and the punching assembly punches holes in the material plate as it passes through.

[0011] It also includes a detection and control module, which is connected to the dual-group feeding assembly, the clamping assembly, and the support drive base. After the detection and control module detects that one tray has finished feeding, it controls the other tray of the dual-group feeding assembly to move to one side of the double-layer conveyor belt assembly to feed. After the detection and control module detects that the next tray has moved between the double-layer conveyor belt assemblies, it controls the clamping assembly to clamp the tray. The linear drive assembly drives the clamping assembly to move the clamped tray closer to the previous tray.

[0012] Optionally, the dual-set feeding assembly includes a moving table and two tray fixing shafts. The two tray fixing shafts are coaxially mounted at both ends of the moving table, and the tray fixing shafts are coaxially fixed to the trays. The tray fixing shafts can drive the fixed trays to feed materials. The support drive base drives the moving table to align the two tray fixing shafts with the double-layer conveyor belt assembly. The detection and control module can control the rotation of the two tray fixing shafts.

[0013] Optionally, the support drive base is equipped with a track feeding plate between the two material tray fixing shafts. The upper end of the track feeding plate is configured as a quarter-ring cylindrical shape coaxial with the material tray fixing shafts, and the lower end of the track feeding plate is horizontally positioned. The upper surface of the horizontal end of the track feeding plate is located between the double-layer conveyor belt assembly.

[0014] Optionally, the double-layer conveyor belt assembly includes a base frame, an upper drive frame, a lower drive frame, and two contact conveyor belts. The two contact conveyor belts are respectively installed inside the upper drive frame and the lower drive frame. The upper drive frame and the lower drive frame drive the two contact conveyor belts to rotate. The upper drive frame is elastically connected to the base frame, and the lower drive frame is fixed to the base frame.

[0015] Optionally, the linear drive assembly includes a side frame, a traction rope, and a winding disc. The traction rope is fixed to the winding disc, the side frame is slidably sleeved on the outer surface of the traction rope, the clamping assembly is slidably sleeved on the outside of the side frame, the traction rope is connected to the clamping assembly, and a torsion drive assembly is installed on the base frame to drive the winding disc to rotate.

[0016] Optionally, the clamping assembly includes an inner plate and an outer frame, both of which are slidably fitted onto the outer surface of the side frame. The inner plate is located inside the outer frame, and the inner side of the outer frame is provided with space for the inner plate to move.

[0017] The outer frame is fixed to the traction rope and elastically connected to the side frame. Two clamping plates are provided on the inner plate near the double-layer conveyor belt assembly. A bidirectional threaded shaft is rotatably installed on the inner plate near the double-layer conveyor belt assembly. The two clamping plates are threaded onto both ends of the bidirectional threaded shaft. The two clamping plates are vertically slidably connected to the inner plate. A gear is fixed at the upper end of the bidirectional threaded shaft. A toothed plate meshes with one side of the gear and is fixed to the outer frame.

[0018] The side frame is equipped with a damping component that applies damping to the inner panel, controlling the delayed movement of the inner panel relative to the outer frame.

[0019] Optionally, two spatial receiving plates are fixed on both sides of the upper surface of the horizontal end of the track feeding plate. The two spatial receiving plates are flared on the side away from the base frame. The upper surface of the lower contact conveyor belt is flush with the upper surface of the horizontal end of the track feeding plate.

[0020] Optionally, the resistance assembly includes a toothed plate and a toothed block, the toothed block meshing with the toothed plate and the toothed block being elastically connected to the inner plate.

[0021] Optionally, the detection control module includes a primary detection controller and a secondary detection controller. The primary detection controller is mounted on the surface of the support drive base and is connected to the support drive base and the material tray fixing shaft frame. After detecting that the material tray has finished discharging, the primary detection controller controls the support drive base to drive the material tray fixed by the other material tray fixing shaft frame to move to one side of the double-layer conveyor belt assembly to discharge material.

[0022] The secondary detection controller is connected to the torsion drive assembly. After the secondary detection controller detects the next material plate, it controls the torsion drive assembly to rotate the winding disc and wind the traction rope, applying tension to the outer frame. This causes the two clamping plates to move closer to each other and clamp the material plate. Then, the traction rope pulls the material plate clamped by the clamping plates closer to the previous material plate. After the secondary detection controller detects that the two material plates are in contact, it controls the winding disc to reverse, and the clamping plates disengage from clamping the material plate.

[0023] In summary, the present invention has the following beneficial technical effects: This invention, through the design of a dual-set feeding assembly and a linear drive assembly for pulling materials, allows the support drive base to directly drive another pre-loaded material tray to the position of the double-layer conveyor belt assembly after the material tray on one tray has been filled. This enables timely replacement of the material tray and reduces the gap between the two material trays after feeding. Then, as the material tray moves between the double-layer conveyor belt assembly, the linear drive assembly drives the clamping assembly to clamp the material tray and quickly pull one end of the material tray close to the previous material tray, further reducing the gap between the two material trays and minimizing the impact on the continuity of subsequent production line processing.

[0024] This invention utilizes a track feeder plate with a quarter-circle shape at the top and a horizontal shape at the bottom, along with two flared spatial receiving plates. When the material tray fixing frame rotates to release material, one end of the material plate slides along the upper surface of the track feeder plate under the constraint of the arc-shaped track feeder plate to the space between the two spatial receiving plates. This allows the released end of the material plate to automatically move between the two contact conveyor belts under the push of the subsequent material tray fixing plate, reducing the workload of the operator.

[0025] This invention utilizes a primary detection controller to control a support drive base to move another material tray, fixed to a fixed shaft frame, to one side of the double-layer conveyor belt assembly after the material tray has been unloaded. A secondary detection controller then detects that the next material plate has moved between the two contact conveyor belts and controls a torsion drive assembly to rotate the winding disc and wind the traction rope, applying tension to the outer frame. This causes the two clamping plates to move closer together, clamping the material plate. The traction rope then pulls the clamped material plate closer to the previous material plate. Once the secondary detection controller detects contact between the two material plates, it controls the winding disc to reverse, disengaging the clamping plates. This eliminates the need for manual control, significantly saving operation time. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0029] This invention discloses a production line for forming the keel of supermarket shelf panels. For example... Figures 1-2 As shown, it includes a feeding assembly 1, a double-layer conveyor belt assembly 2, a flattening assembly 3, a roller auxiliary conveying assembly 4, a punching assembly 5, and a detection and control module 6.

[0030] The feeding assembly 1 includes a support drive base 11 and a double feeding assembly 12. The double feeding assembly 12 is slidably mounted on the upper side of the support drive base 11. The support drive base 11 drives the double feeding assembly 12 to move horizontally on the upper side of the support drive base 11. The double feeding assembly 12 is equipped with two material trays.

[0031] The dual-set feeding assembly 12 can be equipped with two material trays. While one material tray is being fed, the operator can disassemble and replace the other material tray to prepare for the next material tray to be replaced. The support drive base 11 drives the dual-set feeding assembly 12 to move horizontally to the position corresponding to the replacement material tray.

[0032] The double-layer conveyor belt assembly 2 is set on one side of the feeding assembly 1. The material plate passes through the double-layer conveyor belt assembly 2. Both sides of the double-layer conveyor belt assembly 2 are provided with fast following assembly 7. The fast following assembly 7 includes a clamping assembly 71 and a linear drive assembly 72.

[0033] While driving the clamping assembly 71 to move, the linear drive assembly 72 can also drive the clamping assembly 71 to clamp the material plate. That is, when the new material plate moves to the position of the clamping assembly 71, the linear drive assembly 72 drives the clamping assembly 71 to clamp one end of the new material plate. Then, the linear drive assembly 72 pulls the material plate relative to the double-layer conveyor belt assembly 2 and the original material plate. The speed at which the linear drive assembly 72 drives the material plate to move is greater than the conveying speed of the double-layer conveyor belt assembly 2, so that the moving speed of the new material plate is greater than the moving speed of the original material plate. This controls the friction on the outside of the double-layer conveyor belt assembly 2. When pulling the new material plate, it can pull the new material plate to move relative to the double-layer conveyor belt assembly 2, so that the new material plate is closer to the original material plate, reducing the distance between the two material plates.

[0034] The detection and control module 6 is connected to the drive double-group feeding assembly 12, the clamping assembly 71 and the support drive base 11. After detecting that one tray of material has been fed, the detection and control module 6 controls the other tray of the double-group feeding assembly 12 to move to one side of the double-layer conveyor belt assembly 2 to feed material.

[0035] After the detection and control module 6 detects that the material tray that is feeding has finished feeding, it controls the support drive base 11 to drive the double feeding assembly 12 to move horizontally and change the position of the material tray accordingly. After the new material tray moves to the original material tray position, the new material tray feeds the material, reducing the time for changing the new material tray and reducing the gap between the two material trays.

[0036] After the detection and control module 6 detects that the next material plate has moved between the double-layer conveyor belt assembly 2, it controls the clamping assembly 71 to clamp the material plate. The linear drive assembly 72 drives the clamping assembly 71 to move the clamped material plate closer to the previous material plate. After the detection and control module 6 detects that the two material plates are in contact, or when the material plate moves away from the double-layer conveyor belt assembly 2 away from the end of the discharge assembly 1, it controls the clamping assembly 71 to release the clamping of the material plate. The linear drive assembly 72 then controls the clamping assembly 71 to move closer to the discharge assembly 1 to reset.

[0037] The flattening component 3 is located on the side of the double-layer conveyor belt assembly 2 away from the feeding component 1. The material plate passes through the flattening component 3 for flattening. The flattening component 3 has two rows of power-driven pressing rollers inside. When the material plate passes between the two rows of pressing rollers, the upper and lower pressing rollers flatten the material plate.

[0038] The roller auxiliary conveying component 4 is located on the side of the flattening component 3 away from the double-layer conveyor belt component 2, and the roller auxiliary conveying component 4 provides auxiliary support for the material plate.

[0039] After being leveled, the material plate moves to the upper side of the roller auxiliary conveyor assembly 4. The upper end of the roller auxiliary conveyor assembly 4 is equipped with a row of rotatable rollers. The material plate moves on the roller auxiliary conveyor assembly 4 under the push of the double-layer conveyor belt assembly 2.

[0040] The punching assembly 5 is located on the side of the roller auxiliary conveying assembly 4 away from the flattening assembly 3. The roller auxiliary conveying assembly 4 supports and feeds the material plate to the upper side of the punching assembly 5, and the punching assembly 5 punches the material plate that passes through.

[0041] The material plate is supported and conveyed by the roller auxiliary conveyor assembly 4 and moved into the punching assembly 5. The punching assembly 5 is equipped with a punching die plate that can move up and down by power. The material plate passing below is punched in multiple steps. After punching, the material plate continues to be conveyed and undergoes processes such as roll forming, welding, cutting, pickling, phosphating, electrostatic spraying and drying to complete the surface treatment and finished product assembly.

[0042] See Figure 2 In this embodiment, the dual-set feeding assembly 12 includes a moving stage 121 and two tray fixing shafts 122. The two tray fixing shafts 122 are coaxially mounted at both ends of the moving stage 121. The tray fixing shafts 122 are coaxially fixed to the trays. The tray fixing shafts 122 can drive the fixed trays to feed materials. The support drive base 11 drives the moving stage 121 to align the two tray fixing shafts 122 with the double-layer conveyor belt assembly 2. The detection control module 6 can control the rotation of the two tray fixing shafts 122.

[0043] The tray fixing bracket 122 can be disassembled to remove and replace the tray.

[0044] Optionally, the linear drive part of the support drive base 11 can be an electric telescopic rod or a hydraulic cylinder for linear drive, and the specific design is not limited. The rotation drive part of the control tray fixing shaft 122 of the support drive base 11 can be a motor.

[0045] After the detection control module 6 controls the support drive base 11 to drive the moving stage 121 to move, so that the material tray fixing shaft frame 122 moves to one side of the double-layer conveyor belt assembly 2, the corresponding material tray fixing shaft frame 122 is controlled to rotate. Before the two material plates contact, the material tray fixing shaft frame 122 is controlled to rotate quickly, so as to facilitate the subsequent pulling of the material plate closer to the front material plate and reduce the gap between the two material plates. After the two material plates contact, the material tray fixing shaft frame 122 is controlled to return to the original stable speed.

[0046] The support drive base 11 is located between the two material tray fixing shaft frames 122 and a track feeding plate 123 is installed. The upper end of the track feeding plate 123 is set as a quarter ring cylindrical shape coaxial with the material tray fixing shaft frame 122, and the lower end of the track feeding plate 123 is set horizontally. The upper surface of the horizontal end of the track feeding plate 123 is located between the double-layer conveyor belt assembly 2.

[0047] As the material tray is lowered, one end of the material plate falls and is blocked by the arc end of the track feeding plate 123, gradually moving towards the horizontal end of the track feeding plate 123. As the material tray continues to feed material, the outer end of the material plate gradually approaches the double-layer conveyor belt assembly 2 under the continuous feeding of subsequent material trays. Two space receiving plates 124 are fixed on both sides of the upper surface of the horizontal end of the track feeding plate 123. The two space receiving plates 124 are flared on the side away from the base frame 21. The moving end of the material plate is limited by the two flared space receiving plates 124, which helps to push the center of the material plate box track feeding plate 123 to move, effectively preventing the material plate from deviating.

[0048] See Figures 3-8 .

[0049] In an embodiment, the double-layer conveyor belt assembly 2 includes a base frame 21, an upper drive frame 22, a lower drive frame 23, and two contact conveyor belts 24. The two contact conveyor belts 24 are respectively installed inside the upper drive frame 22 and the lower drive frame 23. The upper drive frame 22 and the lower drive frame 23 respectively drive the two contact conveyor belts 24 to rotate. The upper drive frame 22 is elastically connected to the base frame 21, and the lower drive frame 23 is fixed to the base frame 21.

[0050] The optional drive components of the upper drive frame 22 and the lower drive frame 23 can be motors that drive the contact conveyor belt 24 to rotate. The elastic connection between the upper drive frame 22 and the base frame 21 can be an elastic telescopic rod that pushes the upper drive frame 22 closer to the lower drive frame 23, so that the upper contact conveyor belt 24 is close to the lower contact conveyor belt 24 to press and convey the material plate between them.

[0051] The upper surface of the lower contact conveyor belt 24 is flush with the upper surface of the horizontal end of the track feed plate 123, and the material plate that moves out from the horizontal plate of the track feed plate 123 can enter between the two contact conveyor belts 24.

[0052] The linear drive assembly 72 includes a side frame 721, a traction rope 722, and a winding disc 723. The traction rope 722 is fixed to the winding disc 723. The side frame 721 is slidably sleeved on the outer surface of the traction rope 722. The clamping assembly 71 is slidably sleeved on the outside of the side frame 721. The traction rope 722 is connected to the clamping assembly 71. The base frame 21 is equipped with a torsion drive assembly 724, which drives the winding disc 723 to rotate.

[0053] Optionally, the torsion drive assembly 724 may consist of a gear frame capable of moving up and down and a gear disk meshing with it. The gear frame is connected to a hydraulic cylinder, and the rotating disk 723 is coaxially mounted with the gear disk. When the gear frame is controlled to move up and down, it drives the rotating disk 723 to rotate in both directions.

[0054] The clamping assembly 71 includes an inner plate 711 and an outer frame 712. Both the outer frame 712 and the inner plate 711 are slidably sleeved on the outer surface of the side frame 721. The inner plate 711 is located inside the outer frame 712. The inner side of the outer frame 712 is provided with space for the inner plate 711 to move, so that the inner plate 711 can move relative to the outer frame 712.

[0055] The outer frame 712 is fixed to the traction rope 722, and the outer frame 712 is elastically connected to the side frame 721. Optionally, the outer frame 712 and the side frame 721 are connected by a straight spring, which pushes the outer frame 712 to tighten the traction rope 722.

[0056] Two clamping plates 713 are provided on the inner plate 711 near the double-layer conveyor belt assembly 2. A bidirectional threaded shaft 714 is rotatably installed on the inner plate 711 near the double-layer conveyor belt assembly 2. The two clamping plates 713 are threaded onto both ends of the bidirectional threaded shaft 714 respectively. The two clamping plates 713 are vertically slidably connected to the inner plate 711. A gear 715 is fixed at the upper end of the bidirectional threaded shaft 714. A toothed plate 716 meshes on one side of the gear 715. The toothed plate 716 is fixed to the outer frame 712.

[0057] The side frame 721 is equipped with a damping component 717 that applies damping to the inner panel 711, thereby controlling the delayed movement of the inner panel 711 relative to the outer frame 712.

[0058] When the traction rope 722 is wound around the winding disc 723 to pull the outer frame 712, the resistance component 717 generates resistance to the movement of the inner plate 711, causing the inner plate 711 to move relative to the outer frame 712 first. This drives the toothed plate 716 to mesh with the gear 715, which in turn drives the bidirectional threaded shaft 714 to rotate. The two clamping plates 713 mesh with the rotating bidirectional threaded shaft 714 and move closer to each other to clamp the material plate. After the material plate is clamped, the inner plate 711 can no longer move relative to the outer frame 712. When the traction rope 722 continues to pull the outer frame 712, it drives the inner plate 711, the clamping plates 713 and the clamped material plate to move synchronously, ensuring that when the inner plate 711 moves, it first drives the clamping plates 713 to clamp the material plate.

[0059] Similarly, when the disc 723 rotates in the opposite direction, the straight spring pushes the outer frame 712 to move. The outer frame 712 moves relative to the inner plate 711 first, which drives the toothed plate 716 to move in the opposite direction relative to the gear 715, so that the two clamping plates 713 move away from each other and are no longer clamped to the material plate. Then the outer frame 712, the inner plate 711 and the clamping plate 713 reset and move. The linkage ensures that the material plate will not be pulled during the reset and movement.

[0060] See Figure 9 In an embodiment, the resistance component 717 includes a toothed plate 7171 and a toothed block 7172, the toothed block 7172 engaging with the toothed plate 7171 and the toothed block 7172 being elastically connected to the inner plate 711.

[0061] Optionally, the elastic connection between the toothed block 7172 and the inner plate 711 can be an elastic telescopic rod, which pushes the toothed block 7172 to mesh with the toothed plate 7171. The toothed block 7172 generates resistance to the movement of the inner plate 711 by meshing with the toothed plate 7171, and the generated damping can ensure that the clamping plate 713 can stably clamp the material plate.

[0062] The detection control module 6 includes a primary detection controller 61 and a secondary detection controller 62. The primary detection controller 61 is mounted on the surface of the support drive base 11 and is connected to the support drive base 11 and the material tray fixing shaft 122. After detecting that the material tray has finished discharging, the primary detection controller 61 controls the support drive base 11 to drive the material tray fixed by the other material tray fixing shaft 122 to move to one side of the double-layer conveyor belt assembly 2 to discharge material.

[0063] The secondary detection controller 62 is connected to the torsion drive assembly 724. After the secondary detection controller 62 detects the next material plate, it controls the torsion drive assembly 724 to drive the winding disc 723 to rotate and wind the traction rope 722, applying tension to the outer frame 712. This causes the two clamping plates 713 to move closer to each other and clamp the material plate. Then, the traction rope 722 pulls the material plate clamped by the clamping plates 713 closer to the previous material plate. After the secondary detection controller 62 detects that the two material plates are in contact, it controls the winding disc 723 to reverse, and the clamping plates 713 disengage from clamping the material plate. Then, the outer frame 712 is reset under the push of the straight spring.

[0064] The working principle is as follows: Two material trays can be installed through the double-set feeding assembly 12. After the detection and control module 6 detects that one material tray has finished feeding, it controls the other material tray of the double-set feeding assembly 12 to move to one side of the double-layer conveyor belt assembly 2 to feed. At the same time, the other material tray can be disassembled and replaced, reducing the impact of material tray replacement on the continuous processing of the material plate production line. The position of the two material trays is quickly changed to reduce the gap between the two material plates. Then, after the material plate is fed, it moves between the double-layer conveyor belt assemblies 2. After the detection and control module 6 detects that the next material plate has moved between the double-layer conveyor belt assemblies 2, it controls the clamping assembly 71 to clamp the material plate. The linear drive assembly 72 drives the clamping assembly 71 to move the clamped material plate closer to the previous material plate, further reducing the gap between the two material plates. After the detection and control module 6 detects that the two material plates are in contact, it controls the clamping assembly 71 to release the clamping of the material plate, and then controls the linear drive assembly 72 to drive the clamping assembly 71 to reset to the initial position.

[0065] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
