Description

Technical Field

[0001] This utility model relates to the field of material handling devices, specifically a material handling device for key processing. Background Technology

[0002] During stamping operations, after key stamping, the keys are scattered after being cut from the press, which is inconvenient for subsequent production and requires additional personnel to arrange the parts neatly. To solve this problem, a stacking device is usually used to complete the automatic stacking operation. Currently, the common method of stacking keys after punching involves installing a stacking box at the discharge port of the conveyor. Using gravity, the workpieces automatically fall from the discharge port into the stacking box to complete the stacking operation. This traditional stacking...

[0003] The feeding method has achieved automated feeding to a certain extent, which has improved production efficiency to some extent.

[0004] However, the existing devices still have some shortcomings in use, specifically:

[0005] 1) There is usually a large height difference between the bottom surface of the inner cavity of the stacking box and the discharge port. If the stacking box is designed to be deeper, although it can increase the theoretical number of workpieces that can be stacked at one time, the workpieces are prone to skewing when falling due to the long distance they travel during the fall, which affects the neatness and quality of the stacking. Afterwards, manual sorting is required, which increases labor and time costs.

[0006] 2) If the stacking box is designed to be shallower in order to ensure the stability of the material feeding, although it can reduce the probability of workpiece skewing to a certain extent, the number of workpieces stacked at one time will be significantly reduced. This means that the stacking box needs to be replaced more frequently during the continuous feeding process of the punch press, which increases the workload of the staff.

[0007] In summary, a material handling device for key processing is proposed to address the above-mentioned issues. Utility Model Content

[0008] To address the issue of limited quantity of parts that can be stacked at a time in existing technologies, this invention proposes a material handling device for key processing.

[0009] The technical solution adopted by this utility model to solve its technical problem is: a material handling device for key processing, including a belt conveyor, a material handling mechanism is provided on one side of the belt conveyor, the material handling mechanism includes a fixed frame, and a material stacking component is slidably installed on the fixed frame, the number of the material stacking components is two.

[0010] The stacking assembly includes a cylinder, a bracket is fixedly connected to the telescopic end of the cylinder, a stacking shell is fixed to the top of the bracket, the stacking shell is inclined, the stacking shell has a stacking groove, and a pressure sensor is embedded in the bottom surface of the inner wall of the stacking shell.

[0011] Preferably, the belt conveyor is provided with limit plates at both ends of the top, and there is a channel between the two limit plates for the parts to move.

[0012] Preferably, a guide plate is provided on one side of the belt conveyor, and a pair of limiting blocks are provided on the top of the guide plate, with a gap between the two limiting blocks.

[0013] Preferably, an electric linear module is fixedly installed on the mounting bracket. There are two electric linear modules, and the sliding ends of the two electric linear modules are jointly fixed to a support plate. The cylinder is fixed on the support plate.

[0014] Preferably, the material stacking assembly further includes four telescopic rods fixed to the support plate, arranged in a rectangular pattern.

[0015] Preferably, a rectangular groove is formed on the bottom surface of the inner wall of the stacking slot, and a connecting plate is fitted on the rectangular groove, the connecting plate having screw holes.

[0016] Preferably, the cross-sectional projection of the bracket is trapezoidal, and the stacking shell is disposed on the inclined surface of the bracket.

[0017] Preferably, a controller is provided on one side of the fixing frame.

[0018] The advantages of this utility model are:

[0019] 1. This utility model, through the structural design of a cylinder, a stacking shell, and a pressure sensor, lifts the stacking shell in the initial stage of stacking, shortening the height difference between the bottom of the stacking groove and the outlet of the guide plate. This significantly reduces the falling distance of the parts, effectively reducing the risk of skewing caused by various interference factors during the falling process, resulting in neater stacking. When the pressure sensor detects a preset pressure value, the cylinder controls the stacking shell to descend, allowing the stacking shell to continuously receive parts. This ensures that the parts are automatically and neatly stacked, while increasing the number of parts stacked at one time, reducing the frequency of changing the stacking container, and improving work efficiency.

[0020] 2. Through the structural design of rectangular groove, connecting plate and vertical rod, this utility model allows the vertical rod to be inserted into the hole of the part, rotated to connect with the connecting plate, and then the vertical rod can be lifted to remove all the parts stacked in the groove, making it convenient for workers to unload materials;

[0021] 3. The present invention uses a bracket design to tilt the stacking shell after installation, thereby shortening the actual effective falling distance when parts fall from the guide plate onto the stacking slot, and further reducing the risk of tilting. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a material handling device for key processing. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A material handling device for key processing includes a belt conveyor 1, a material handling mechanism 4 is provided on one side of the belt conveyor 1, the material handling mechanism 4 includes a fixed frame 401, and two material stacking components are slidably installed on the fixed frame 401.

[0031] The stacking assembly includes a cylinder 404, with a bracket 406 fixedly connected to the telescopic end of the cylinder 404. A stacking shell 407 is fixed to the top of the bracket 406. The stacking shell 407 is inclined and has a stacking groove 4070. A pressure sensor 408 is embedded in the bottom surface of the inner wall of the stacking shell 407.

[0032] Reference Figure 1 and Figure 2 Limiting plates 2 are provided at both ends of the top of the belt conveyor 1, and there is a channel between the two limiting plates 2 for parts to move.

[0033] A guide plate 3 is provided on one side of the belt conveyor 1, and a pair of limiting blocks 301 are provided on the top of the guide plate 3, with a gap between the two limiting blocks 301.

[0034] Specifically, mounting plates are installed on the frames on both sides of the belt conveyor 1. The guide plate 3 is rotatably connected to the two mounting plates via a rotating shaft. One end of the rotating shaft passes through the mounting plate and is connected to the output end of the stepper motor. The stepper motor can drive the guide plate 3 to rotate, thereby blocking the parts conveyed on the belt conveyor 1, which facilitates the alternating use of the two material stacking components.

[0035] The width of the channel and the interval are the same, which ensures the stable transport of parts. The end of the belt conveyor 1 away from the guide plate 3 is matched with the discharge port of the stamping machine to transport the stamped parts to the belt conveyor 1.

[0036] Reference Figure 3 An electric linear module 402 is fixedly installed on the fixed frame 401. There are two electric linear modules 402. The sliding ends of the two electric linear modules 402 are jointly fixed to the support plate 403. The cylinder 404 is fixed on the support plate 403.

[0037] When the stacking shell 407 on one of the stacking components is full of parts, the electric linear module 402 can move the stacking shell 407 full of parts out and move the stacking shell 407 without parts to the material drop port of the guide plate 3 for stacking operation.

[0038] Reference Figure 3 The material stacking assembly also includes four telescopic rods 405 fixed on the support plate 403, arranged in a rectangular pattern.

[0039] The telescopic ends of the telescopic rods 405 are fixed to the bottom of the bracket 406. The four telescopic rods 405 are evenly distributed and work in conjunction with the cylinder 404 to achieve stable lifting and lowering of the bracket 406.

[0040] Reference Figure 4 A rectangular groove 409 is provided on the bottom surface of the inner wall of the stacking groove 4070. A connecting plate 410 is fitted on the rectangular groove 409, and the connecting plate 410 has screw holes.

[0041] The stacking assembly also includes a vertical rod 411. In use, the vertical rod 411 is inserted into the hole of the stacked parts, and then rotated to connect it with the connecting plate 410. The vertical rod 411 can then be lifted upwards to remove all the parts stacked in the stacking slot 4070, making it convenient for workers to unload the materials.

[0042] Reference Figure 4 The cross-sectional projection of the bracket 406 is trapezoidal, and the stacking shell 407 is set on the inclined surface of the bracket 406, which makes the stacking shell 407 inclined. This shortens the actual effective falling distance when the parts fall from the guide plate 3 onto the stacking slot 4070, further reducing the risk of skewing.

[0043] Reference Figure 3 A controller is provided on one side of the mounting bracket 401. The controller is electrically connected to the pressure sensor 408, the electric linear module 402 and the stepper motor respectively.

[0044] Working principle: After being unloaded from the stamping machine, the parts enter the belt conveyor 1 and are conveyed neatly towards one end of the guide plate 3 by the limiting plates 2. At this time, the controller controls the cylinder 404 to rise, which causes the bracket 406 to rise, and then the stacking shell 407 to rise. This changes the height difference between the bottom surface of the stacking groove 4070 and the guide plate 3, allowing the parts to fall more stably on the stacking groove 4070. As more and more parts are stacked on the stacking groove 4070, when the pressure sensor 408 detects the preset pressure value, the controller controls the cylinder 404 to descend, so that the stacking shell 407 can continuously receive parts. This ensures that the parts are automatically and neatly stacked, increases the number of parts stacked at one time, reduces the frequency of changing the stacking container, and improves work efficiency.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
