Description

Technical Field

[0001] The present application relates to the field of material conveying devices, and in particular to an inclined feeding mechanism. Background Art

[0002] In modern industrial production, the application of automated equipment is becoming increasingly widespread, especially in the field of material transportation. The improvement of the degree of automation is directly related to the improvement of production efficiency. Material transportation not only needs to ensure high efficiency and stability, but also needs to adapt to materials of various shapes and sizes. For materials of conventional shapes, such as blocks or cylinders, due to their regular geometric characteristics, they can usually be transported one by one, so transportation is relatively simple. However, for thin sheet-like workpieces, due to their small size and light weight, transporting them one by one takes a long time and is inefficient, so batch transportation is usually adopted. During the batch transportation process, these workpieces are often stacked together, and before entering the processing link, the stacked workpieces must be separated one by one for individual processing.

[0003] In the related art, in order to solve the problem of separating thin sheet workpieces, the following methods are usually adopted: First, manual separation, that is, the operator manually separates the workpieces one by one. Although this method is simple, it is inefficient, labor-intensive, and prone to errors; second, the use of air blowing, using compressed air to blow the workpieces away one by one. This method is suitable for lighter workpieces, but it is not effective for workpieces with heavier weight or greater surface friction; third, separation using a vibrating disk, which gradually separates the workpieces through vibration, but this requires additional vibration equipment, which increases the complexity and cost of the system.

[0004] However, the above methods generally have some shortcomings in practical applications. Manual separation relies on manpower and cannot be fully automated, which reduces production efficiency; airflow blowing has high requirements on the workpiece material and environmental conditions, and its scope of application is limited; vibration disk separation requires an additional power source, which increases the cost of the equipment and the difficulty of maintenance. In addition, these methods also have certain limitations in separation accuracy and stability, and it is difficult to meet the requirements of high-precision processing. Therefore, the development of a device that can efficiently and stably separate thin-sheet workpieces has become a key technical issue to improve the degree of production automation and production efficiency. Utility Model Content

[0005] In order to achieve automatic separation of sheet workpieces in a stacked state, the present application provides an inclined loading mechanism.

[0006] The inclined feeding mechanism provided in this application adopts the following technical solutions:

[0007] An inclined feeding mechanism includes a silo and a pushing assembly;

[0008] The bottom of the silo is provided with a discharge port; the pushing assembly has a pushing plate and a first driving part; the pushing plate is provided with a workpiece groove, and the pushing assembly also includes a slide rail, and the pushing plate is slidably connected to the slide rail; the first driving part is used to drive the pushing plate to move to the bottom of the silo and align the workpiece groove with the discharge port, so that the sheet workpiece falls into the workpiece groove.

[0009] By adopting the above technical solution, the sheet workpieces are stacked and placed in the hopper, and automatically move downward under the influence of their own weight, and the push plate moves horizontally. When the workpiece trough moves below the discharge port, the workpiece falls into the workpiece trough, and the push plate moves in the opposite direction to take the workpiece out of the hopper, thereby realizing the separation of the sheet workpieces.

[0010] Preferably, the depth of the workpiece groove is less than or equal to the thickness of the workpiece.

[0011] By adopting the above technical solution, the depth of the workpiece groove is less than or equal to the thickness of the workpiece, which can ensure that only one sheet workpiece falls into the workpiece groove at a time, avoiding the jamming phenomenon caused by multiple workpieces entering the workpiece groove at the same time, and improving the reliability and efficiency of workpiece separation.

[0012] Preferably, a material guide plate is provided in the material bin, and the material guide plate is arranged at an angle, and a plurality of stacked sheet workpieces are staggered and placed on the material guide plate.

[0013] By adopting this technical solution, the inclined guide plate allows sheet workpieces to slide along the plate under their own weight, achieving natural alignment and orderly downward movement of the workpieces. The staggered placement of workpieces on the guide plate effectively reduces adhesion, improves the reliability of workpiece separation, and further enhances the stability and efficiency of workpiece conveying.

[0014] Preferably, a guide member is further provided in the hopper, and the guide member is arranged parallel to the guide plate, and a space for placing the sheet workpiece is reserved between the guide member and the guide plate.

[0015] By adopting the above technical solution, the guide member is arranged parallel to the guide plate, and a space is left between the two for placing the sheet workpiece. This can ensure the stability and correct position of the sheet workpiece on the guide plate, prevent the workpiece from shifting or getting stuck during the falling process, and improve the accuracy and reliability of workpiece separation.

[0016] Preferably, the guide member is slidably connected to the side wall of the silo to achieve adjustment of the distance between the guide member and the guide plate.

[0017] By adopting the above technical solution, the guide member is slidably connected to the side wall of the hopper, and the distance between the guide member and the guide plate can be flexibly adjusted to adapt to sheet workpieces of different thicknesses, ensuring that the workpiece can smoothly enter the workpiece slot, thereby improving the applicability and flexibility of the equipment.

[0018] Preferably, a gap is left between the bottom end of the guide member and the pushing plate, and the vertical height of the gap is greater than one times the thickness of the sheet workpiece and less than two times the thickness of the sheet workpiece.

[0019] By adopting the above technical solution, the gap design between the bottom end of the guide and the pushing plate enables a single sheet workpiece to pass smoothly, while preventing multiple workpieces from entering the workpiece slot at the same time, ensuring that only one workpiece is brought out by the pushing plate at a time, thereby improving the accuracy and reliability of workpiece separation.

[0020] Preferably, the silo includes two hoppers arranged opposite to each other, and the opposite sides of the two hoppers are both opened, and the two ends of the sheet workpiece are respectively located inside the two hoppers.

[0021] By adopting the above technical solution, the hopper includes two hoppers arranged opposite each other, each of which is open on one side. This allows the ends of the sheet workpiece to be located within each hopper. This design ensures the stable placement of the sheet workpieces within the hopper, preventing them from tilting or shifting during stacking, thereby improving the conveying accuracy and stability of the workpieces. Furthermore, the open design of the hoppers facilitates the rapid positioning and loading of workpieces, further enhancing the efficiency of the entire loading mechanism.

[0022] Preferably, the pushing assembly further includes a push rod and a second driving portion for driving the push rod to move horizontally, the push rod is arranged parallel to the workpiece slot, and the push rod is used to push the sheet workpiece in the workpiece slot.

[0023] By adopting the above technical solution, the push rod can accurately push the sheet workpiece in the workpiece groove, ensuring that the workpiece can be pushed out stably during the movement of the pushing plate, avoiding the occurrence of workpiece jamming or tilting, and improving the reliability and efficiency of workpiece separation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The design of the push plate and workpiece slot realizes the automatic separation of sheet workpieces, improving the degree of production automation and production efficiency;

[0026] 2. The inclined setting of the guide plate and the coordination of the guide parts make the workpieces arranged in order in the hopper, reducing the jamming phenomenon and ensuring the smooth transportation of the workpieces;

[0027] 3. The depth of the workpiece slot is reasonably designed, which can effectively prevent multiple workpieces from falling into the slot at the same time, further improving the accuracy of workpiece separation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] The inventors of this application have discovered that in industrial production, when thin sheet workpieces 3 are transported to the processing stage, in order to facilitate individual processing of the workpieces 3, it is necessary to separate the stacked sheet workpieces 3. However, the separation of the workpieces 3 currently still requires manual intervention, resulting in a low degree of automation.

[0033] To this end, this application mainly adopts the following inclined feeding mechanism, referring to Figure 1 and Figure 2 It includes a silo 1 and a pushing assembly 2; a discharge port is provided at the bottom of the silo 1; a pushing plate 21 and a first driving part of the pushing assembly 2; a workpiece groove 22 is provided on the pushing plate 21, and the pushing assembly 2 also includes a slide rail 23, and the pushing plate 21 is slidably connected to the slide rail 23; the first driving part is used to drive the pushing plate 21 to move to the bottom of the silo 1 and align the workpiece groove 22 with the discharge port so that the sheet workpiece 3 falls into the workpiece groove 22, thereby achieving the effect of automatically separating the sheet workpiece 3 and improving production efficiency. The following is a further detailed description of this application.

[0034] The inclined loading mechanism provided in the embodiment of the present application specifically includes a silo 1 and a push assembly 2. A discharge port is provided at the bottom of the silo 1, and the push assembly 2 includes a push plate 21 and a first drive unit. The push plate 21 is provided with a workpiece slot 22, and the push assembly 2 also includes a slide rail 23, with the push plate 21 being slidably connected to the slide rail 23. The first drive unit is used to drive the push plate 21 to move below the silo 1 and align the workpiece slot 22 with the discharge port, so that the sheet workpiece 3 falls into the workpiece slot 22. Through this design, the sheet workpiece 3 is automatically separated, thereby improving production efficiency.

[0035] The silo 1 is used to store stacked sheet workpieces 3. A discharge port is provided at the bottom of the silo 1. The discharge port can be adjusted according to the size and shape of the workpieces 3 to ensure that the workpieces 3 can smoothly fall into the workpiece slot 22. The pushing assembly 2 includes a pushing plate 21 and a first drive unit. The pushing plate 21 is provided with a workpiece slot 22. The depth of the workpiece slot 22 is less than or equal to the thickness of the workpiece 3, which ensures that only one workpiece 3 is pushed out at a time.

[0036] The workpiece groove 22 can be in various forms such as a V-shaped groove, a U-shaped groove or a rectangular groove, and the specific selection depends on the shape and thickness of the workpiece 3.

[0037] The push plate 21 is slidably connected to the slide rail 23. The slide rail 23 can be a variety of forms, such as a linear guide or a ball screw, to ensure smooth movement of the push plate 21. The first drive unit can be a cylinder, an electric motor, or other linear drive device, which is used to drive the push plate 21 along the slide rail 23. The cylinder has the characteristics of fast response and reliable operation, which is suitable for applications where rapid sorting is required; the electric motor has high precision and controllability, which is suitable for applications requiring precise control. The stroke of the first drive unit can be adjusted according to the size of the workpiece 3 and the height of the silo 1 to ensure that the push plate 21 can be accurately moved to the bottom of the silo 1 and the workpiece slot 22 is aligned with the discharge port.

[0038] A guide plate 11 is installed within the hopper 1. The guide plate 11 is tilted, and several stacked sheet workpieces 3 are staggered on the guide plate 11. The guide plate 11 guides the workpieces 3 along a predetermined path, preventing them from getting stuck or shifting during their descent. The angle of the guide plate 11 can be adjusted based on the shape and thickness of the workpieces 3 to ensure smooth descent. The guide plate 11 can be made of stainless steel, aluminum alloy, or other wear-resistant materials to extend its service life.

[0039] In the present application, the side wall of the silo 1 can be tilted and used as a guide plate 11 to reduce the number of parts of the equipment and lower production costs.

[0040] The hopper 1 is also equipped with a guide member 12, which is arranged parallel to the guide plate 11. A space is left between the guide member 12 and the guide plate 11 for placing the sheet workpiece 3. The guide member 12 limits the lateral movement of the workpiece 3, preventing it from shifting during its descent. The guide member 12 can take the form of a sliding rail or a fixed baffle, depending on the shape and size of the workpiece 3. The spacing between the guide members 12 can be adjusted according to the size of the workpiece 3 to ensure smooth descent.

[0041] For some workpieces 3 with notches, the guide member 12 can also cooperate with the notches of the workpiece 3, thereby further improving the stability of the workpiece 3.

[0042] The guide member 12 is slidably connected to the sidewall of the silo 1 to adjust the distance between the guide member 12 and the guide plate 11. The guide member 12 can be connected to the sidewall of the silo 1 using a sliding guide rail or screw thread to facilitate adjustment of the distance. The adjustment range of the guide member 12 can be adjusted based on the size of the workpiece 3 and the height of the silo 1 to ensure smooth sliding of the workpiece 3.

[0043] A gap is left between the bottom end of the guide 12 and the push plate 21. The vertical height of this gap is greater than one and less than two times the thickness of the sheet workpiece 3. This gap is designed to ensure that the workpiece 3 can smoothly exit the guide 12 and enter the workpiece slot 22, while also preventing the workpiece 3 from getting stuck or shifting when exiting the guide 12. The size of the gap can be adjusted according to the thickness and shape of the workpiece 3 to ensure smooth entry into the workpiece slot 22.

[0044] The hopper 1 includes two hoppers 13 positioned opposite each other. Both hoppers 13 have openings on opposite sides, and the ends of the sheet-shaped workpiece 3 are located within each hopper 13. This design ensures that the workpiece 3 remains stable during its descent, preventing it from shifting or getting stuck. The opening width of the hopper 13 can be adjusted according to the size of the workpiece 3 to ensure smooth descent.

[0045] The sheet workpieces 3 are stacked and placed in the silo 1 and automatically move downward under the influence of their own weight. When the push plate 21 moves to the bottom of the silo 1, the workpiece slot 22 aligns with the discharge port, and the workpiece 3 falls into the workpiece slot 22. The push plate 21 moves in the opposite direction, bringing the workpiece 3 out of the silo 1, thereby separating the sheet workpieces 3. Through this design, the automatic separation of the sheet workpieces 3 is achieved, and production efficiency is improved. Compared with existing methods such as manual separation, airflow blowing, and vibration plate separation, the inclined feeding mechanism of this embodiment has a higher degree of automation and separation accuracy, which can effectively improve production efficiency and product quality.

[0046] In order to move the workpiece 3 out of the workpiece groove 22 , the pushing assembly 2 further includes a push rod 24 and a second driving part 25 for driving the push rod 24 to move horizontally. The push rod 24 is arranged parallel to the workpiece groove 22 and is used to push the sheet workpiece 3 in the workpiece groove 22 .

[0047] After the push plate 21 removes the workpiece 3 from the hopper 1, the push rod 24 pushes the workpiece 3 out of the workpiece slot 22, ensuring that the workpiece 3 can smoothly enter the next process. The push rod 24 can be made of stainless steel, aluminum alloy, or other wear-resistant materials to extend its service life. The diameter and length of the push rod 24 can be adjusted according to the size and shape of the workpiece 3 to ensure that the push rod 24 can smoothly push the workpiece 3.

[0048] The second drive unit 25 can be a pneumatic cylinder, electric motor, or other linear drive device. Pneumatic cylinders offer fast response and reliable operation, making them suitable for rapid sorting. Electric motors, on the other hand, offer high precision and controllability, making them suitable for applications requiring precise control. The stroke of the second drive unit 25 can be adjusted based on the size of the workpiece 3 and the position of the push plate 21 to ensure that the ejector pin 24 accurately pushes the workpiece 3.

[0049] The ejector pin 24 is positioned parallel to the workpiece slot 22 and slightly longer than the workpiece slot 22 to ensure that it completely covers the workpiece slot 22. The front end of the ejector pin 24 can be designed to be curved or tapered to reduce resistance during ejection. The installation position of the ejector pin 24 can be adjusted according to the size and shape of the workpiece 3 to ensure that the ejector pin 24 can smoothly push the workpiece 3.

[0050] The implementation principle of this embodiment is as follows: the sheet workpieces 3 are stacked and placed in the silo 1, and automatically move downward under the influence of their own weight. When the pushing plate 21 moves to the bottom of the silo 1, the workpiece slot 22 is aligned with the discharge port, and the workpiece 3 falls into the workpiece slot 22. The pushing plate 21 moves in the opposite direction to bring the workpiece 3 out of the silo 1. At this time, the second driving part 25 is started, and the workpiece 3 is pushed out of the workpiece slot 22 through the push rod 24 to ensure that the workpiece 3 can smoothly enter the next process. Through this design, the automatic separation and transmission of the sheet workpieces 3 are realized, and the production efficiency is improved. Compared with the existing methods such as manual separation, airflow blowing and vibration disk separation, the inclined feeding mechanism of this embodiment has a higher degree of automation and separation accuracy, which can effectively improve production efficiency and product quality.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
