It provides a sheet metal feeding machine with weighing capabilities, including a complete feeding machine and a set of weighing modules integrated on the feeding machine's base. The feeding machine includes a material rack and a feeding device. The material rack is used to hold sheet metal coils, and the feeding device is used to drive the sheet metal coils to rotate and feed them.

Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and in particular to a sheet metal feeding machine with weighing function. Background Technology

[0002] Sheet metal parts, as fundamental components of modern industry, have been deeply integrated into daily life and high-end manufacturing. With the surge in demand for personalized consumption and small-batch customization, the retail and after-sales markets have placed higher demands on the sheet metal parts supply model of "various individual parts and scattered quantities".

[0003] However, traditional sheet metal feeding machines only have simple storage and separation functions. Workers pre-stack the punched, sheared, or bent sheet metal parts into the hopper, and then manually count, weigh, and adjust for discrepancies before packaging. This model is adequate for mass production, but it reveals the following significant shortcomings in retail scenarios:

[0004] 1. Without a real-time weighing module, the quantity of materials to be fed depends on manual estimation, resulting in a large discrepancy between the actual weight received by the customer and the order, and frequent reshipments or returns.

[0005] 2. The feeding cycle is fixed and cannot be dynamically started and stopped based on weighing feedback, often resulting in pauses such as "manual removal after overfeeding" or "secondary replenishment after underfeeding". Utility Model Content

[0006] In view of the above practical problems and the shortcomings of the existing technology, the main technical problem to be solved by this utility model is to provide a sheet metal feeding machine with weighing function, so as to realize the accurate feeding of sheet metal parts by "as needed weight".

[0007] To solve the above-mentioned technical problems, this application provides a sheet metal part feeding machine with weighing function, which adopts the following technical solution:

[0008] A sheet metal part feeding machine with weighing function includes a feeding machine and a set of weighing modules integrated on the base of the feeding machine; the feeding machine includes a material rack and a feeding device, the material rack is used to place sheet metal part rolls, and the feeding device is used to drive the sheet metal part rolls to rotate and feed them.

[0009] The base integrates a set of four large-tonnage weighing modules, which are arranged in a rectangular shape on both sides of the base. The entire feeding machine is suspended on the four large-tonnage weighing modules via the base.

[0010] The weighing module collects the changes in the total weight of the current coil and the sheet metal that has been released in real time, and feeds the data back to the controller of the feeding machine to control the start and stop of the feeding device.

[0011] In a preferred embodiment, the weighing module is a pressure weighing module; the pressure weighing module includes a top plate, a bottom plate and a high-precision pressure weighing sensor, the bottom plate is installed on the ground, and the top plate is connected to the base.

[0012] In a preferred embodiment, a support seat is welded to each side of the base near its corner, and the support seat is welded to the top plate or locked with high-strength bolts.

[0013] In a preferred embodiment, a support seat is welded to each side of the base near its corners, and the support seat is welded and fixed to the pressure surface of the weighing module or locked by high-strength bolts.

[0014] In a preferred embodiment, the base has a pre-reserved enclosed wiring channel and a waterproof cable hole at the position corresponding to the weighing module. The cable of the weighing module passes through the cable hole and is connected to the controller via the wiring channel.

[0015] In a preferred embodiment, the weighing module is a wireless weighing module, and the weighing module is electrically connected to the controller.

[0016] In a preferred embodiment, the top of the support base is integrally provided with a support rib extending upward, and the support rib is welded to the base.

[0017] In summary, this application has the following beneficial effects:

[0018] This utility model sets up four large-tonnage weighing modules and uses a "suspended whole machine + four-point rectangular weighing" architecture to ensure that the entire load of the feeding machine and the material roll is applied to the sensor without damage, realizing real-time weighing during the feeding process; the controller directly starts and stops the feeding device according to the weight change, achieving "stop when the weight is reached", and the weight error of small retail orders is ≤±1%, eliminating the need for secondary manual weighing.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This embodiment provides a sheet metal part feeding machine 1 with weighing function, aiming to solve the problems of "inability to accurately feed materials on demand, low efficiency of manual weighing, and easy errors" in retail and small-batch scenarios. Its key structural features are as follows: A weighing module 2 is integrated on the base 14 of the sheet metal part feeding machine 1, forming an integrated closed loop of "feeding-weighing". The sheet metal part feeding machine 1 includes a material rack 11 and a feeding device 12. Sheet metal part rolls 3 can be placed on the material rack 11. The feeding device 12 drives the sheet metal part rolls 3 to rotate, thus feeding the materials. The weighing module 2 collects the current total weight change of the roll and the sheet metal already fed out in real time, and feeds back the weight signal to the controller in analog or digital form. The controller has a pre-set single-piece weight algorithm that can automatically deduct the fixed tare weight of the material rack 11, mandrel, etc., and calculate the target feeding weight based on the target weight and set a set value. When the real-time weight reaches the set value, the feeding device 12 immediately brakes, achieving accurate stopping on demand.

[0029] With the above settings, this embodiment only needs to add a weighing module 2 and control program to the original feeding machine. This can compress the traditional three-stage process of "feeding first, weighing then, and making up the difference" into a one-stage process of "feeding while weighing and stopping when the weight is reached". This reduces weight error, eliminates manual secondary handling and making up the difference, significantly reduces waste of sheet metal parts and after-sales disputes, and meets the retail needs of "small batch, multiple varieties, and fast delivery" in the era of personalized customization.

[0030] The sheet metal feeding machine 1 with weighing function provided in this embodiment includes a feeding machine body and a feeding machine bracket 13 for support. The material rack 11 and feeding device 12 are both mounted on the feeding machine bracket 13. A base 14 is provided at the bottom of the feeding machine bracket 13. The base 14 integrates a set of four large-tonnage weighing modules 2. The large-tonnage weighing modules 2 are pressure-type weighing modules 2. The four pressure-type weighing modules 2 are arranged in a rectangular shape and jointly bear the weight of the whole machine and the sheet metal roll, realizing real-time weighing and precise control during the feeding process.

[0031] The pressure weighing module 2 includes a top plate 21, a bottom plate 22, and a high-precision pressure weighing sensor 23. The top plate 21 and bottom plate 22 of the pressure weighing module 2 will press against each other under pressure. The bottom plate 22 can be directly mounted on the ground, while the top plate 21 serves as the pressure-bearing surface and can be connected to the base 14. The pressure weighing sensor 23 is located inside the pressure weighing module 2, and its weighing range is from 3 kg to 300 tons. The pressure weighing module 2 is an existing weighing device, such as the CWC weighing module, CW weighing module, FW weighing module, etc., which will not be described in detail here.

[0032] This embodiment uses a pressure-type weighing module 2, with the base plate 22 directly on the ground and the top plate 21 independently supporting the base 14. No modification to the ground foundation is required during installation, which ensures a large tonnage range and reduces the flatness requirements of the installation surface.

[0033] A support base 15 is welded to each of the two sides near the corners of the base 14 and rigidly connected to the top plate 21 of the pressure weighing module 2, forming a four-point suspension node. The support base 15 can be directly welded to the top plate 21, or it can be locked to the top plate 21 by high-strength bolts 4. The four support bases 15 are connected one-to-one with the top plates 21 of the four pressure weighing modules 2, thereby suspending the entire base 14 on the four pressure weighing modules 2, so that all loads are transmitted to the pressure weighing sensor 23 without loss, realizing real-time and high-precision weighing during the material feeding process. The support base 15 directly connects to the top plate 21 (pressure surface) of the pressure weighing module 2, eliminating the need for transition parts and reducing force transmission loss; the same support base 15 is compatible with the pressure surface interfaces of different brands of weighing modules 2, improving interchangeability and spare parts versatility.

[0034] A support rib 16 extends integrally from the top of the support base 15. The support rib 16 is continuously welded to the upper surface of the base 14 to form a triangular reinforcement area, which significantly improves the bending and shear stiffness of the suspension node. Reinforcing pads are welded to the two sides of the base 14 at the corresponding positions of the support base 15, and beveled to be fully welded to the support base 15 and the support rib 16 on three sides, which together improves the bending and shear resistance of the suspension node and ensures that the pressure weighing module 2 does not deform under long-term load.

[0035] The base 14 has a pre-installed enclosed cable routing channel 17, with waterproof cable holes 18 on both sides facing the pressure-type weighing module 2. The cable of the pressure-type weighing module 2 enters the channel through the cable holes 18 and converges along the channel to the controller, achieving fully concealed wiring and avoiding dragging and wear. Alternatively, a wireless pressure-type weighing module 2 can be used, which is electrically connected to the controller, eliminating the need for cables. The signal is sent directly to the controller via Wi-Fi or Bluetooth, resulting in no exposed cables at the bottom of the base 14, simplifying installation and maintenance.

[0036] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
