Description

Technical Field

[0001] This invention relates to the technical field of equipment for producing shelf uprights, specifically an integrated rolling, welding, and cutting equipment for producing shelf uprights. Background Technology

[0002] As one of the most important core load-bearing components in the warehouse racking industry, the quality of rack uprights directly affects the racking's load-bearing capacity, stability, and overall quality. To ensure upright production quality while improving production efficiency, various integrated production equipment is frequently used by relevant personnel.

[0003] The applicant discovered through a search that a Chinese patent, "A Fully Automatic Forming Device for Large Shelf Uprights," with publication number "CN111571034A," discloses a patent that uses a laser cutting head to cut the uprights, thereby improving the quality of the finished shelf uprights and increasing cutting efficiency. At the same time, through the cooperation between the handling robot, the upright clamping device, and the upright raw material positioning and stacking mechanism, automatic loading and unloading can be achieved, resulting in a higher degree of automation, reducing manual labor intensity, reducing production costs, and improving the finished product qualification rate.

[0004] Traditional large-scale shelving uprights often use pre-formed square or flat steel tubes as raw materials, followed by subsequent operations such as cutting and drilling. The production process of the aforementioned technical solutions and most such devices on the market is inherently discrete and intermittent. From raw material loading, positioning and clamping, cutting and processing to unloading, there are significant material transfer and waiting times between each stage, making continuous material flow on the production line impossible, thus creating a significant bottleneck in production efficiency. Secondly, although these solutions improve automation, they still rely on robotic arms for material handling between discrete workstations, and the overall production cycle is limited by the auxiliary time for handling and positioning. Furthermore, this type of technology relies on purchasing or pre-producing pre-formed steel tubes, and does not involve the continuous forming process of the upright's main profile from metal strip to a closed section. This is equivalent to separating the profile forming and subsequent processing into two independent production stages, significantly increasing production steps, material inventory, and overall management costs. Therefore, we propose an integrated roller rolling, welding, and cutting equipment for shelving upright production. Summary of the Invention

This invention, by incorporating a grinding roller brush and a second electric motor, enables immediate preliminary grinding of the weld seam after welding, effectively removing some welding slag and burrs and improving welding quality. Simultaneously, by setting up dust suction holes and an exhaust fan, grinding debris and contaminants from the profile are absorbed into one side of the filter box, promptly removing debris and contaminants adhering to the profile surface or near the weld seam, preventing adverse effects on subsequent processing steps or the final product appearance quality, thus ensuring product consistency and yield. Furthermore, by incorporating heat dissipation nozzles, the same exhaust system simultaneously collects and filters grinding dust while guiding the purified air to the cutting edge for forced cooling, rapidly reducing the profile temperature to a safe level for subsequent processing. This reduces the waiting time for natural cooling between processes, helping to maintain the efficient and continuous production rhythm of this technical solution. Attached Figure Description

[0072] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0073] Please see Figures 1-11 The present invention provides a technical solution: an integrated rolling, welding and cutting equipment for producing shelf uprights, including a frame 1, a control mechanism 2, a feeding mechanism, a guiding component 5, a continuous rolling forming mechanism, a closed welding equipment 10 and a cutting equipment 3.

[0074] The control mechanism 2 includes an electrical control device, which is electrically connected to the continuous rolling forming mechanism, the closed welding device 10, and the cutting device 3 via a DP bus. The feeding mechanism is used to carry and unfold the metal coil. The guiding component 5 is used to guide the unfolded coil into the continuous rolling forming mechanism. The continuous rolling forming mechanism is used to roll the straight metal strip into a profile with a closed seam. The closed welding device 10 is used to weld the closed seam of the formed profile. The cutting device 3 is used to cut the welded profile to a preset length.

[0075] Under the action of the feeding mechanism, the metal coil gradually unfolds and enters the guiding component 5. Then, the guiding component 5 operates, smoothly and accurately guiding the unfolded strip into the continuous rolling forming mechanism. Subsequently, the continuous rolling forming mechanism performs multiple and progressive rolling operations on the strip, thereby rolling the straight strip into a column profile of the specified shape. The formed column is immediately conveyed to the closed welding equipment 10, which then welds the closed seam of the formed profile. The welded profile continues to be conveyed to one side to the cutting equipment 3, which accurately cuts the welded profile. Through this continuous production process, the production of multi-step shelving columns can be integrated into a single continuous production line, eliminating the material transfer and waiting time during traditional sequential processing, and significantly improving production efficiency.

[0076] Furthermore, the implementation of the cutting equipment 3 includes, but is not limited to, a mechanical cutting device or a laser cutting device, and the type of cutting equipment 3 can be determined according to the requirements of the cut surface quality and the material characteristics.

[0077] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 2 and Figure 3 The feeding mechanism includes a load-bearing frame 4, an internal support assembly 9, and a rotating mechanism 11.

[0078] The load-bearing frame 4 is fixedly installed on one side of the frame 1; the inner support assembly 9 is used to fix the metal coil; the rotating mechanism 11 is used to drive the metal coil and the inner support assembly 9 to rotate. The rotating mechanism 11 is a rotational power source, which can be one of an electric motor, a hydraulic motor or a servo motor.

[0079] Furthermore, the inner support assembly 9 includes a support plate 901, a slider 902, a lifting cylinder 903, an inner support plate 906, and a pushing mechanism.

[0080] The bearing plate 901 is fixedly connected to the end of the output shaft of the rotating mechanism 11; the slider 902 is constrained by the bearing plate 901 and is slidably connected to the bearing plate 901; the lifting cylinder 903 is fixedly installed on the slider 902; at least one connecting plate 905 is hinged between the inner support plate 906 and the lifting cylinder 903; the pushing mechanism is used to drive the lifting cylinder 903 to move linearly.

[0081] Under the action of the pushing mechanism, the lifting cylinder 903 moves to one side. With the connection of the connecting plate 905, the slider 902 then drives the inner support plate 906 to unfold outward until the inner support plate 906 is in close contact with the inner side of the metal coil, thus fixing the metal coil to one side of the bearing plate 901.

[0082] Furthermore, the driving mechanism includes a drive screw 907, a drive ring 908, and a rotating shaft 904.

[0083] The drive screw 907 is limited to rotate on the bearing plate 901; the drive ring 908 is threadedly connected to the drive screw 907 and is fixedly connected to the lifting cylinder 903; the rotating shaft 904 is fixedly installed at the end of the drive screw 907 and is used to connect a manual operating tool or an external power source.

[0084] The drive screw 907 is rotated by the staff using manual operating tools or an external power source, which in turn drives the ring 908 to move the lifting cylinder 903 to one side.

[0085] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The material guiding component 5 includes a guide frame 501, a horizontal guiding mechanism, and a centering guiding mechanism.

[0086] Furthermore, the guide frame 501 is fixedly installed on the frame 1; the horizontal guide mechanism includes several horizontal limit rollers 506; the centering guide mechanism includes a position adjustment component and a driving mechanism.

[0087] The horizontal limiting roller 506 is mounted on the guide frame 501 and is used to adjust the radial position of the unfolded strip. Two position adjusting components are provided and are located on both sides of the guide frame 501. The driving mechanism is used to drive the position adjusting components on both sides to move linearly in opposite directions.

[0088] Under the action of the driving mechanism, the position adjustment component moves from both sides toward the center until it contacts the outer side of the strip, thereby aligning the position of the strip.

[0089] Furthermore, the position adjustment component includes a mounting plate 502 and several vertical rollers 507, which are limited to rotate on the mounting plate 502 and are made of silicone material.

[0090] Since the vertical roller 507 can rotate and is made of silicone, the friction between the vertical roller 507 and the sidewall of the strip can be greatly reduced, and damage to the strip can be reduced.

[0091] Furthermore, a drive mechanism is installed on one side of the mounting plate 502, which is used to drive the vertical roller 507 to rotate.

[0092] Under the action of the drive mechanism, the vertical roller 507 rotates at an appropriate speed to ensure that it is adapted to the moving speed of the strip, thereby further reducing the damage to the strip during the centering process and helping to ensure the forming quality of the strip in the future.

[0093] Furthermore, the drive mechanism includes a rotating rod 508, a first electric motor 503, a drive gear 509, and a connecting gear 510.

[0094] The rotating rod 508 is rotatably mounted on one side of the mounting plate 502, and the vertical roller 507 is fixedly connected to the end of the rotating rod 508; the output end of the first motor 503 is connected and fixed to one of the rotating rods 508; the drive gear 509 is sleeved and fixed on one side of the rotating rod 508; and the connecting gear 510 is meshed between the two drive gears 509.

[0095] During the conveying of the strip, the first motor 503 operates, and under the meshing of the drive gear 509 and the connecting gear 510, the vertical roller 507 rotates at an appropriate speed.

[0096] Furthermore, the drive mechanism includes a bidirectional lead screw 505 and a limit rod 504.

[0097] The mounting plate 502 is threaded to both sides of the bidirectional lead screw 505, and one end of the bidirectional lead screw 505 is connected to a manual operating tool or an external power source; the mounting plate 502 is constrained by the limiting rod 504 and is slidably connected to it.

[0098] The bidirectional lead screw 505 is rotated by the staff using manual operating tools or an external power source, and the mounting plate 502 then drives the vertical roller 507 to move from the outside to the inside.

[0099] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 7 and Figure 8 The continuous rolling forming mechanism includes a reinforcing rib pressing assembly 6 and an edge clamping assembly 7.

[0100] Among them, the reinforcing rib pressing assembly 6 is used to roll out continuous longitudinal reinforcing ribs on the strip; the edge pressing and closing assembly 7 is used to gradually bend the two sides of the strip and finally press them together to form a profile with a closed longitudinal seam.

[0101] Furthermore, the reinforcing rib pressing assembly 6 includes several reinforcing upper rollers 601 and reinforcing lower rollers 602.

[0102] The upper reinforcing roller 601 has multiple raised ribs; the lower reinforcing roller 602 has multiple grooves that match the raised ribs. When the strip passes through, the raised ribs cooperate with the grooves to roll and form longitudinal reinforcing ribs in the middle of the strip.

[0103] Furthermore, the edge-pressing and closing assembly 7 includes several forming upper rollers 701, limiting lower rollers 702, and pressing rollers 703.

[0104] In the inlet section, the cavities of the forming upper roller 701 and the limiting lower roller 702 smoothly connect with the outlet cavity of the reinforcing rib pressing assembly 6 to guide the workpiece. In the middle section, the cavities of the forming upper roller 701 and the limiting lower roller 702 are provided with specific guide surfaces to gradually gather the bent edges of the strip towards the centerline. In the outlet section, the cavity of the pressing roller 703 is constructed as a precise narrow slit to apply pressure to the gathered edges, pressing them tightly together to form a uniformly spaced closed longitudinal seam for welding.

[0105] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 9 , Figure 10 and Figure 11 Downstream of the enclosed welding equipment 10, a grinding assembly 8 is also installed. The grinding assembly 8 includes a drive frame 810, a grinding roller brush 806, and a second electric motor 812.

[0106] The drive frame 810 is detachably mounted on the frame 1; the grinding roller brush 806 is rotatably mounted on the drive frame 810; and the output end of the second motor 812 is connected to the end of the grinding roller brush 806.

[0107] After the closed seam of the formed profile is welded, the second motor 812 runs and the grinding roller 806 rotates to perform preliminary grinding on the weld, which can effectively remove some of the welding slag and burrs and improve the welding quality.

[0108] Furthermore, a chip-blocking mechanism is also installed on one side of the grinding roller brush 806. The chip-blocking mechanism includes a chip-blocking housing 802 sleeved on the outside of the grinding roller brush 806. During the grinding process, the flying chips will be blocked by the chip-blocking housing 802, effectively preventing these chips from contaminating the operating environment.

[0109] Furthermore, the chip-blocking housing 802 is a hollow structure, and the inner side of the chip-blocking housing 802 is densely covered with multiple dust suction holes 805. The chip-blocking mechanism also includes a dirt suction mechanism, which includes a filter box 801, a connecting pipe 803, and an induced draft fan 811.

[0110] The filter box 801 is fitted with a sealing cover 804, and several filter screens 809 are installed on one side of the filter box 801; one end of the connecting pipe 803 passes through one side of the filter box 801 and extends into the inner cavity of the filter box 801; the suction end of the blower 811 passes through the other side of the filter box 801 and extends into the inner cavity of the filter box 801.

[0111] During the rotation of the grinding roller brush 806, the induced draft fan 811 operates, creating a negative pressure state inside the filter box 801. Grinding debris and contaminants from the profile are absorbed into one side of the filter box 801. Timely removal of debris and contaminants adhering to the profile surface or near welds prevents them from adversely affecting subsequent processing steps or the final product appearance quality, thus ensuring product consistency and yield. Furthermore, timely collection of grinding debris and contaminants prevents them from scattering, significantly improving the hygiene and safety of the work area.

[0112] Furthermore, an air outlet pipe 808 is fixedly connected to the air outlet end of the induced draft fan 811, and a heat dissipation spray pipe 807 is fixedly connected to the end of the air outlet pipe 808.

[0113] Workers aim the heat dissipation nozzle 807 at the cut edge of the profile. Filtered air is blown towards the cut edge through the heat dissipation nozzle 807. Through the same set of air intake system, while collecting and filtering grinding dust, the purified air is directed to the cut edge for forced cooling. This can quickly reduce the temperature of the profile to a range where it can be safely touched or processed. It reduces the waiting time for natural cooling between processes and helps maintain the efficient and continuous production rhythm of this technical solution.

[0114] Working principle: When relevant personnel need to use this technical solution to produce rack uprights, the operator first uses external hoisting equipment to hoist the metal coil to one side of the load-bearing frame 4, and then rotates the drive screw 907, causing the inner support plate 906 to unfold outwards until the metal coil is fixed. Then the rotating mechanism 11 runs, unfolding the metal coil outwards.

[0115] The operator feeds the end of the strip into the guide frame 501, where the horizontal limiting roller 506 initially constrains the vertical position of the strip. Then, the operator rotates the bidirectional lead screw 505, and the mounting plate 502 drives the vertical roller 507 to move from both sides towards the center until the vertical roller 507 contacts the outer side of the metal strip, thus centering and guiding the strip to ensure it enters the next process in a precisely aligned state.

[0116] After centering, the strip then enters between the upper reinforcing roller 601 and the lower reinforcing roller 602, where it is rolled to form continuous longitudinal reinforcing ribs.

[0117] Subsequently, this portion of the strip enters between the forming upper roller 701 and the limiting lower roller 702, where the two side edges are gradually bent and converged towards the center. Finally, in the precise narrow slit of the pressing roller 703, the two side edges are gradually pressed tightly together, forming a closed longitudinal slit with uniform gaps, becoming the column profile to be welded.

[0118] The formed column profile is immediately transported to the closed welding equipment 10, which welds the closed longitudinal seam on the profile, making the column profile a closed whole.

[0119] During the grinding process of the welded profiles via the grinding assembly 8, the second motor 812 operates, and the grinding roller 806 rotates to perform preliminary grinding of the weld seam, removing welding slag and burrs from the column surface. During this process, the induced draft fan 811 operates, and any flying debris is temporarily stored in the filter box 801.

[0120] The processed upright profiles are then conveyed to cutting equipment 3, which cuts the profiles to a preset length. This process continues, allowing for continuous production of shelf uprights.

[0121] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
