Description

Technical Field

[0001] This utility model relates to the field of chip conveyor detection technology, and in particular to a detection device for iron chip conveyors. Background Technology

[0002] In normal operation, an automatic chip conveyor has a chip cart placed underneath it for easy chip transfer. However, a problem arises: the chips always fall into the middle of the chip cart, gradually accumulating. If the chips are not dispersed to the sides or removed in time, clumps of chips may be rolled back into the chip conveyor, causing it to jam and become damaged, making repairs difficult.

[0003] Chinese patent application CN108274296A discloses a detection device for preventing the backflow of iron chips in a CNC machine tool chip conveyor. The device includes a safety light curtain array switch, a programmable logic controller (PLC), a visual indicator unit, and a CNC system. The safety light curtain array switch is installed on both sides of the discharge port of the CNC machine tool chip conveyor to detect the accumulation of iron chips and issue an alarm output signal. The PLC processes the alarm output signal and generates an output signal. The visual indicator unit displays the status of the iron chips based on the output signal from the PLC. The CNC system displays relevant information on the system operation panel based on the output signal from the PLC. The detection device uses the safety light curtain array switch to control the start and stop of the chip conveyor, and simultaneously outputs an alarm through the PLC and the CNC system. This patent uses image recognition to detect iron chip accumulation, which is less reliable than physical detection.

[0004] Therefore, providing a detection device that relies on physical methods to detect the accumulation of iron filings is an urgent problem that needs to be solved. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a detection device for a chip conveyor.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] According to one aspect of the present invention, a detection device for a chip conveyor is provided, comprising a chip conveyor and a collection cart. The chip conveyor includes a chip discharge port, through which the chip conveyor discharges iron chips into the collection cart. The device further includes a position detection unit, a stroke triggering unit, an alarm unit, and a processing unit. The alarm unit and the processing unit are both installed on the chip conveyor. The processing unit is communicatively connected to the stroke triggering unit and the alarm unit, respectively. The position detection unit is installed at the outlet of the chip discharge port, and the stroke triggering unit is installed on the side of the chip discharge port. The position detection unit and the stroke triggering unit are movably connected.

[0008] As a preferred technical solution, the chip discharge port includes a side plate unit, and the positioning detection unit includes a baffle, a cam and a first rotating shaft. The first rotating shaft is mounted on the side plate unit and one end of the first rotating shaft passes through the side plate unit. The baffle is mounted on the first rotating shaft located inside the side plate unit, and the cam is mounted on the first rotating shaft located outside the side plate unit.

[0009] As a preferred technical solution, the baffle and the cam rotate coaxially.

[0010] As a preferred technical solution, the stroke triggering unit includes a trigger plate, a second rotating shaft, and a limit switch. The second rotating shaft and the limit switch are both mounted on the side plate unit. The trigger plate is mounted on the second rotating shaft. The two ends of the trigger plate are respectively arranged corresponding to the cam and the limit switch, and the trigger plate is in contact with the cam.

[0011] As a preferred technical solution, the baffle includes an upper baffle and a lower baffle, wherein the weight of the lower baffle is greater than the weight of the upper baffle.

[0012] As a preferred technical solution, the trigger plate includes a left trigger plate and a right trigger plate, the left trigger plate is in contact with the cam, and the weight of the left trigger plate is greater than the weight of the right trigger plate.

[0013] As a preferred technical solution, the weight of the lower baffle is greater than the weight of the left trigger plate.

[0014] As a preferred technical solution, the cam is a hollow cam or a plastic cam.

[0015] As a preferred technical solution, the weight of the cam is less than the weight of the right trigger plate.

[0016] As a preferred technical solution, the alarm unit includes an indicator light and a speaker, which are respectively communicatively connected to the processing unit.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model uses a positioning detection unit and a stroke triggering unit to work together to physically detect the accumulation of iron filings. When the iron filings accumulate too much, the positioning detection unit and the stroke triggering unit are triggered in sequence, and an alarm signal is issued through the alarm unit. The structure is simple and reliable. Alternatively, the positioning detection unit can move the iron filings to both sides to achieve peak shaving and valley filling.

[0019] 2. In this utility model, the baffle and cam rotate coaxially. When the iron filings accumulate to the point that the baffle rotates clockwise or counterclockwise, the cam rotates clockwise or counterclockwise as well. The trigger plate rotates on the second rotating axis under its own gravity and comes into contact with the cam. The limit switch can be triggered by the clockwise or counterclockwise rotation of the cam.

[0020] 3. The upper baffle of this utility model is less heavy than the lower baffle, and the baffle can automatically maintain a vertical state when there are no iron filings.

[0021] 4. The left trigger plate of this utility model is heavier than the right trigger plate, so that the left trigger plate can always be in contact with the cam.

[0022] 5. The weight of the lower baffle of this utility model is greater than the weight of the left trigger plate, so that when the baffle is reset, it lifts the trigger plate, causing the right trigger plate to move away from the stroke unit.

[0023] 6. The cam of this utility model is hollow or made of plastic, so that the weight of the cam is kept relatively light, and the weight of the cam itself is avoided from affecting the triggering or resetting of the baffle. Attached Figure Description

[0029] 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, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1-4As shown, a detection device for a chip conveyor includes a chip conveyor 1 and a collection cart 2. The chip conveyor 1 includes a chip discharge port 11, through which the chip conveyor 1 discharges iron chips into the collection cart 2. The device also includes a position detection unit, a stroke triggering unit, an alarm unit, and a processing unit. The alarm unit and the processing unit are both installed on the chip conveyor 1. The processing unit is communicatively connected to the stroke triggering unit and the alarm unit, respectively. The position detection unit is installed at the outlet of the chip discharge port 11, and the stroke triggering unit is installed on the side of the chip discharge port 11. The position detection unit and the stroke triggering unit are movably connected.

[0032] The iron filings accumulate in the collection vehicle 2 and push the positioning detection unit or the positioning detection unit pushes the iron filings to move to both sides.

[0033] The chip discharge port 11 includes a side plate unit, and the positioning detection unit includes a baffle 3, a cam 6, and a first rotating shaft 4. The first rotating shaft 4 is mounted on the side plate unit and one end of the first rotating shaft 4 passes through the side plate unit. The baffle 3 is mounted on the first rotating shaft 4 located inside the side plate unit, and the cam 6 is mounted on the first rotating shaft 4 located outside the side plate unit. The baffle 3 and the cam 6 rotate coaxially.

[0034] In this embodiment, iron filings fall from the discharge port 11 of the chip conveyor 1 into the collection cart 2, accumulating and piling up in a pyramid shape, wider at the bottom and narrower at the top, with the side areas relatively empty and not fully utilizing the space. Furthermore, excessively high accumulation of iron filings can cause clumps to be drawn back into the chip conveyor 1, leading to jamming and damage, making repair difficult. This invention employs a physical detection method: when the iron filings accumulate to a certain level, they push the baffle 3 to rotate, thereby causing the cam 6 to rotate. After the cam 6 rotates, its overall height changes from its highest point to its lowest point. When the iron filings are removed, the baffle 3 automatically resets under its own influence, and the cam 6 returns to its initial position.

[0035] The chip discharge port 11 is surrounded by side walls, with the opposite side walls forming a group, and the side plate unit being any group of side walls.

[0036] The stroke triggering unit includes a trigger plate 5, a second rotating shaft 8, and a limit switch 7. The second rotating shaft 8 and the limit switch 7 are both mounted on the side plate unit. The trigger plate 5 is mounted on the second rotating shaft 8. The two ends of the trigger plate 5 are respectively arranged to correspond to the cam 6 and the limit switch 7. The trigger plate 5 and the cam 6 are in contact.

[0037] In this embodiment, the trigger plate 5 rotates around the second rotating shaft 8. One end of the trigger plate 5 is in contact with the cam 6, and the limit switch 7 is located on the rotation path of the other end of the trigger plate 5. The trigger plate 5 as a whole can be regarded as a seesaw, so that the trigger plate 5 triggers the limit switch 7.

[0038] The baffle 3 includes an upper baffle and a lower baffle, with the lower baffle weighing more than the upper baffle. The trigger plate 5 includes a left trigger plate and a right trigger plate, with the left trigger plate contacting the cam 6, and the left trigger plate weighing more than the right trigger plate. The lower baffle weighs more than the left trigger plate.

[0039] In this embodiment, by adjusting the position of the first rotating shaft 4 on the baffle 3, the baffle 3 is divided into an upper baffle and a lower baffle. The center of gravity is manually controlled so that the weight of the upper baffle is less than the weight of the lower baffle, ensuring that the baffle 3 automatically remains vertical without external force (i.e., the pushing force of accumulated iron filings), achieving automatic reset. Similarly, by adjusting the position of the second rotating shaft 8 on the trigger plate 5, the center of gravity is manually controlled, dividing the trigger plate 5 into a left trigger plate and a right trigger plate. The weight of the left trigger plate is greater than the weight of the right trigger plate, ensuring that the left trigger plate descends without external force (i.e., the lifting force provided by the cam 6), and the right trigger plate descends. The trigger plate will rise and trigger the limit switch 7. In addition, the left trigger plate is heavier, so this end of the left trigger plate will always keep in contact with the cam 6. The weight of the lower baffle is greater than the weight of the left trigger plate, that is, the baffle 3 can overcome the weight of the left trigger plate. During the resetting process of the baffle 3, the cam 6 will push up the trigger plate 5, so that the right trigger plate is away from the limit switch 7. Since it is impossible to determine which side of the baffle 3 the iron filings will accumulate on, this utility model adopts the form of the cam 6. When the baffle 3 rotates, the right trigger plate will move closer to the limit switch 7 regardless of whether the cam 6 rotates clockwise or counterclockwise, thus avoiding the limitation of a single rotation direction.

[0040] In addition, since the iron filings will be piled up in a pyramid shape with large gaps on both sides, if the piled iron filings cannot push the baffle 3, the iron filings will move to the gaps on both sides of the baffle 3 under the obstruction of the baffle 3, so as to achieve uniform accumulation of iron filings and smooth out the peaks and fill the valleys.

[0041] The cam 6 is a hollow cam or a plastic cam. The weight of the cam 6 is less than the weight of the right trigger plate.

[0042] In this embodiment, in order to avoid the influence of the cam 6 itself, it is necessary to reduce the weight of the cam 6 as much as possible. Using hollow or plastic materials can reduce the weight of the cam 6, and the weight of the cam 6 will not affect the reset process of the baffle 3.

[0043] The alarm unit includes an indicator light and a speaker, which are respectively communicatively connected to the processing unit.

[0044] In this embodiment, the indicator light and speaker provide visual and auditory reminders, respectively; the processing unit uses a microcontroller to receive the limit switch 7 signal in real time. After receiving the trigger signal, it controls the indicator light and speaker to emit reminders. A microcontroller such as the AT89C51 can be used.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
