A material receiving and counting device

Abstract

This invention provides a material receiving and counting device. It solves the problem that the actual number of aluminum sheets finally stacked in the receiving device does not match the theoretical number counted by the system based on the number of stamping cycles. This invention includes a receiving rack and a receiving assembly mounted on the receiving rack. The receiving assembly includes a receiving plate and a stop bar. One end of the receiving plate connects to the outlet of the stamping machine, and the other end is inclined downwards. The receiving plate has a storage station. The stop bar is perpendicular to the receiving plate. The aluminum sheets slide down the inclined receiving plate until they are stopped by the stop bar, so that the aluminum sheets are stacked sequentially in the storage station. The receiving assembly also includes a distance sensor, which is located directly above the storage station to detect the top height of the stacked aluminum sheets. The advantage of this invention is that by measuring the actual height of the aluminum sheet stack using the distance sensor, and then calculating the actual number of sheets based on the known thickness of a single aluminum sheet, the counting result is accurate and reliable.

Description

Technical Field

[0001] This utility model relates to the technical field of aluminum plate processing equipment, and in particular to a material receiving and counting device. Background Technology

[0002] In aluminum sheet stamping production, a stamping press presses aluminum sheets into circular sheets, which are then conveyed out by a conveyor. Typically, a receiving device is installed at the stamping press's outlet to catch the delivered aluminum sheets and stack them sequentially. In existing technology, the counting of aluminum sheets generally relies on the number of stamping passes, assuming that each stamping pass produces one qualified aluminum sheet that successfully falls into the receiving device.

[0003] However, this counting method has significant drawbacks. In actual production, due to factors such as mold wear, positioning deviations, or material issues, the stamped aluminum sheets may fail to properly detach from the aluminum plate and enter the conveying process; or, operators may pick up individual defective scrap aluminum sheets midway. These situations will result in a discrepancy between the actual number of aluminum sheets ultimately stacked in the receiving device and the theoretical number counted by the system based on the number of stampings. This counting error directly affects the accuracy of production management, causing difficulties for subsequent inventory management and production statistics. Summary of the Invention

[0004] The main purpose of this invention is to address the shortcomings of existing technologies by providing an aluminum sheet receiving counting device that can directly and accurately count the received aluminum sheets.

[0005] The objective of this utility model can be achieved through the following technical solutions: A material receiving and counting device is characterized in that it includes a material receiving frame and a material receiving assembly disposed on the material receiving frame. The material receiving assembly includes a material receiving plate and a stop bar. One end of the material receiving plate is connected to the discharge port of a stamping machine, and the other end is inclined downward. The material receiving plate has a material storage station. The stop bar is perpendicular to the material receiving plate. Aluminum sheets slide down the inclined material receiving plate until they are stopped by the stop bar, so that the aluminum sheets are stacked sequentially in the material storage station. The material receiving assembly also includes a distance measuring sensor, which is disposed directly above the material storage station and is used to detect the top height of the stacked aluminum sheets in the material storage station.

[0006] In the aforementioned material receiving and counting device, the receiving rack is further equipped with an adjustment device for adjusting the tilt angle of the receiving plate to ensure that the aluminum sheets slide down smoothly and are stacked neatly.

[0007] In the aforementioned material receiving and counting device, the adjusting device includes a mounting plate, a front rotating shaft, a rear rotating shaft, and a telescopic assembly. The front and rear rotating shafts are horizontally rotatably mounted at the front and rear ends of the receiving plate, respectively. The receiving plate is rotatably mounted on the mounting plate via the rear rotating shaft. There are two sets of telescopic assemblies, each located at one end of the front rotating shaft. Each telescopic assembly includes a screw, an upper threaded sleeve, and a lower threaded sleeve. The upper threaded sleeve is fixedly connected to the front rotating shaft, and the lower threaded sleeve is rotatably mounted on the mounting plate via a horizontal pin. The screw is divided into an upper section and a lower section along its length, with opposite thread directions. The upper and lower sections are screwed to the upper and lower threaded sleeves, respectively. Rotating the screw causes the upper and lower threaded sleeves to move closer or further apart. By driving the upper and lower threaded sleeves closer or further apart, the tilt angle of the receiving plate is infinitely adjustable by lifting or lowering the front end of the receiving plate.

[0008] In the aforementioned material receiving and counting device, the receiving rack is further equipped with a lifting device for driving the entire receiving assembly to rise and fall. The lifting device lowers the receiving assembly by a height equal to the thickness of a single aluminum sheet in a single operation, ensuring that each aluminum sheet falls from the outlet of the stamping machine at a consistent distance. Whenever a new aluminum sheet falls into the storage station, the receiving assembly descends by the thickness of one aluminum sheet, ensuring that the vertical distance from the outlet of the stamping machine to the stacked aluminum sheets remains consistent, effectively avoiding problems such as aluminum sheet bouncing, displacement, or uneven stacking caused by changes in drop height.

[0009] In the aforementioned material receiving and counting device, the lifting device includes a base plate, which is mounted on the material receiving frame. The mounting plate is vertically slidably mounted on the base plate, and the base plate is also provided with a lifting drive component for driving the mounting plate to move vertically back and forth.

[0010] In the aforementioned material receiving and counting device, the lifting drive component includes a motor, a lead screw, and a nut. The lead screw is fixedly connected to the mounting plate, and the nut is sleeved on the outer circumference of the lead screw and connected to the motor for transmission. The motor drives the nut to rotate and drives the lead screw and the mounting plate to lift as a whole.

[0011] In the aforementioned material receiving and counting device, a guide assembly is further provided between the mounting plate and the base plate. The guide assembly includes guide rods and guide sleeves. Several guide rods are fixedly connected to the mounting plate, and several guide sleeves corresponding to the positions of each guide rod are fixedly installed on the base plate. Each guide rod is inserted into its corresponding guide sleeve.

[0012] In the aforementioned material receiving and counting device, the lifting device further includes a displacement sensor used to detect the displacement of the mounting plate relative to the base plate. This allows for precise control of the descent stroke, ensuring that the single descent height matches the thickness of the aluminum sheet.

[0013] In the aforementioned material receiving and counting device, there are two sets of material receiving components, which are arranged horizontally at intervals. The material receiving frame is also equipped with a translation drive to drive the two sets of material receiving components to move back and forth, allowing them to alternately connect with the outlet of the stamping machine. When the aluminum sheets on one set of material receiving components accumulate to a predetermined quantity, the translation drive activates, moving the other empty set of material receiving components to connect with the outlet of the stamping machine, thereby achieving uninterrupted continuous material receiving operation and improving production efficiency.

[0014] In the aforementioned material receiving and counting device, the translation drive includes a translation cylinder. Two sets of material receiving assemblies are mounted on a base plate, which is horizontally slidable on the material receiving frame via a guide rail slider. The base plate is fixedly connected to the piston rod of the translation cylinder, which drives the base plate and the two sets of material receiving assemblies to move as a whole, thus achieving station switching.

[0015] In the aforementioned material receiving and counting device, the ranging sensor is a laser ranging sensor. Its high precision and non-contact measurement advantages ensure the accuracy of aluminum sheet stack height detection.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Accurate and reliable counting: The actual height of the aluminum sheet stack is directly measured by a distance sensor installed above the storage station. The actual number of sheets is then calculated based on the known thickness of each sheet. This fundamentally avoids counting errors caused by aluminum sheets not falling or being picked up, ensuring accurate and reliable counting results.

[0017] 2. High stacking quality: The lifting device lowers the receiving component by one sheet thickness after receiving each aluminum sheet, maintaining a constant drop height. This effectively prevents the aluminum sheets from bouncing, slipping, or being scratched due to impact, ensuring the neatness and surface quality of the stacked aluminum sheets.

[0018] 3. High adaptability: The tilt angle adjustment device can adjust the appropriate downward sliding angle for aluminum sheets of different sizes and surface properties, ensuring smooth conveying. The design of the dual receiving assembly and translation drive component enables non-stop operation, greatly improving the equipment's efficiency and continuous production capacity.

[0019] 4. High degree of automation: The entire process of receiving, stacking, lowering, counting and workstation switching can be completed automatically, reducing manual intervention, reducing labor intensity, and facilitating the realization of automated and intelligent production management.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1 and Figure 2 As shown, the material receiving and counting device of this utility model includes a material receiving frame 1 and a material receiving assembly disposed on the material receiving frame 1. The material receiving assembly includes a material receiving plate 2 and a stop bar 3. One end of the material receiving plate 2 is connected to the discharge port of the stamping machine, and the other end is inclined downward. The material receiving plate 2 has a material storage station. The stop bar 3 is perpendicular to the material receiving plate 2. The aluminum sheet slides down the inclined material receiving plate 2 until it is blocked by the stop bar 3, so that the aluminum sheets are stacked in the material storage station in sequence.

[0023] The receiving assembly also includes a distance sensor 17, which is positioned directly above the storage station. This sensor detects the top height of the stacked aluminum sheets at the storage station and calculates the actual number of sheets based on the known thickness of each sheet, achieving accurate counting. A mounting base is provided on the top of the stop bar 3, and the distance sensor 17 is mounted on this base. The distance sensor 17 is a laser distance sensor. Its high precision and non-contact measurement advantages ensure the accuracy of aluminum sheet stack height detection.

[0024] like Figure 3 and Figure 4As shown, the receiving rack 1 is also equipped with an adjustment device for adjusting the tilt angle of the receiving plate 2 to ensure that the aluminum sheets slide smoothly and are stacked neatly. The adjustment device includes a mounting plate 4, a front rotating shaft 5, a rear rotating shaft 6, and a telescopic assembly. The front rotating shaft 5 and the rear rotating shaft 6 are respectively horizontally rotatably mounted at the front and rear ends of the receiving plate 2. The receiving plate 2 is rotatably mounted on the mounting plate 4 via the rear rotating shaft 6. There are two sets of telescopic assemblies, which are respectively mounted at both ends of the front rotating shaft 5. The telescopic assembly includes a screw 7, an upper screw sleeve 8, and a lower screw sleeve 9. The upper screw sleeve 8 is fixedly connected to the front rotating shaft 5. The lower screw sleeve 9 is rotatably mounted on the mounting plate 4 via a horizontal pin. The screw 7 is divided into an upper section and a lower section along its length. The threads of the upper section and the lower section have opposite directions. The upper section and the lower section are screwed to the upper screw sleeve 8 and the lower screw sleeve 9, respectively. Rotating the screw 7 can drive the upper screw sleeve 8 and the lower screw sleeve 9 to move closer or further apart. By driving the upper screw sleeve 8 and the lower screw sleeve 9 to move closer or further apart, the tilt angle of the receiving plate 2 can be infinitely adjusted by lifting or lowering the front end of the receiving plate 2.

[0025] like Figure 3 As shown, the receiving rack 1 is also equipped with a lifting device for driving the receiving assembly to rise and fall as a whole. The lifting device lowers the receiving assembly by the thickness of a single aluminum sheet at a time, ensuring that each aluminum sheet falls from the outlet of the stamping machine at a consistent distance. Whenever a new aluminum sheet falls into the storage station, the receiving assembly lowers by the thickness of one aluminum sheet, ensuring that the vertical distance from the outlet of the stamping machine to the stacked aluminum sheets remains consistent, effectively avoiding problems such as aluminum sheet bouncing, displacement, or uneven stacking caused by changes in drop height. The lifting device includes a base plate 10, which is mounted on the receiving rack 1. The mounting plate 4 is vertically slidably mounted on the base plate 10, and the base plate 10 is also equipped with a lifting drive component for driving the mounting plate 4 to rise and fall vertically back and forth.

[0026] The lifting drive component includes a motor 11, a lead screw 12, and a nut. The lead screw 12 is fixedly connected to the mounting plate 4. The nut is sleeved on the outer circumference of the lead screw 12 and is connected to the motor 11 for transmission. The motor 11 drives the nut to rotate, thereby driving the lead screw 12 and the mounting plate 4 to lift as a whole. A guide assembly is also provided between the mounting plate 4 and the base plate 10. The guide assembly includes guide rods 14 and guide sleeves 13. Several guide rods 14 are fixedly connected to the mounting plate 4, and several guide sleeves 13, each corresponding to one of the guide rods 14, are fixedly mounted on the base plate 10. Each guide rod 14 is inserted into its corresponding guide sleeve 13. The lifting device also includes a displacement sensor 16, which is used to detect the displacement of the mounting plate 4 relative to the base plate 10. This allows for precise control of the stroke of each descent, ensuring that the single descent height is consistent with the thickness of the aluminum sheet.

[0027] like Figure 2As shown, there are two sets of receiving components, horizontally spaced apart. The receiving rack 1 is also equipped with a translation drive to move the two sets of receiving components back and forth, allowing them to alternately connect with the outlet of the stamping machine. When the aluminum sheets on one set of receiving components reach a predetermined quantity, the translation drive activates, moving the other empty set of receiving components to connect with the outlet of the stamping machine, thus achieving uninterrupted continuous receiving operations and improving production efficiency. The translation drive includes a translation cylinder 15. Both sets of receiving components are mounted on a base plate 10, which is horizontally slidable on the receiving rack 1 via a guide rail slider. The base plate 10 is fixedly connected to the piston rod of the translation cylinder 15, which drives the base plate 10 and the two sets of receiving components to move horizontally, achieving station switching.

[0028] The working process of this utility model is as follows: In the initial state, a set of receiving components aligns with the discharge port. The stamped aluminum sheet falls into the receiving plate 2 and slides to the storage station. The laser rangefinder 17 detects an increase in height, and the control system instructs the lifting device to descend by one aluminum sheet thickness. This cycle continues until the number of aluminum sheets at that station reaches the set value. At this point, the translation cylinder 15 actuates, switching the station. Throughout the process, the system can accurately and in real time grasp the actual number of each stack of aluminum sheets by continuously monitoring the height data.
