A dedicated counting device and counting method for engine connecting rod water removal equipment

Abstract

A dedicated counting device and method for engine connecting rod water removal equipment includes: a frame, a flap hinged to the frame, a probe bracket mounted on the frame and located above one end of the flap, and a probe detection switch mounted on the probe bracket. The flap consists of an integrally formed pressure section, a raised section, and a bent plate. The bending point of the bent plate is fixed to a flip hinge shaft. The pressure section is located directly below the belt conveyor outlet end, and the raised section is located directly below the probe detection switch. A connecting rod falling naturally from the belt conveyor outlet end contacts and presses down on the pressure section. During the falling process, the pressure section drives the raised section to flip upward. The raised section blocks the probe detection switch, interrupting the probe detection switch signal. After the connecting rod slides off the pressure section, the raised section automatically falls back to its original position under gravity, and the probe detection switch signal is restored. The advantage of this invention is that it uses the falling posture of the connecting rod to mechanically lift the flap, replacing direct photoelectric triggering with physical triggering, thus avoiding miscounting of the connecting rod without spacing from the source.

Description

Technical Field

[0001] This invention relates to the field of engine connecting rod technology, and specifically to a special counting device and counting method for engine connecting rod water removal equipment. Background Technology

[0002] Existing dewatering equipment using linkages mostly employs through-beam photoelectric switches for product counting. However, this method has several drawbacks in actual production applications: 1. The linkages are tightly arranged on the conveyor belt with no gaps between them, which easily leads to false counting and missed counting by the photoelectric switch; 2. The irregular shape and structure of the linkages, with varying sizes and heights, result in large fluctuations and poor stability of the through-beam photoelectric detection signal, leading to low overall counting accuracy; 3. Under high-speed mass production conditions, the sensor signal response is lagging, making it difficult to adapt to high-efficiency production lines and hindering accurate and stable data statistics. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide a special counting device and counting method for engine connecting rod dehydration equipment, which is used to achieve stable counting, unaffected by connecting rod spacing, unaffected by time and temperature, and to achieve accurate statistics of the output after connecting rod dehydration, so as to overcome the shortcomings of the prior art.

[0004] This invention provides a dedicated counting device for engine connecting rod dewatering equipment, comprising: a frame, a flap hinged to the frame, a probe bracket mounted on the frame and located above one end of the flap, and a probe detection switch (sensor) mounted on the probe bracket. The frame is fixedly connected below the belt conveyor outlet of the connecting rod via the dewatering machine. Two hinge seats are symmetrically arranged on the frame, and a flip hinge is rotatably connected within the two hinge seats. The flap consists of an integrally formed pressure-bearing section (T-shaped), a raised section (T-shaped), and a bent plate (L-shaped) connecting the pressure-bearing section and the raised section. The bending point of the bent plate is fixedly connected to the flip hinge. On the shaft, the weight of the raised section is greater than the weight of the bearing section, and the weight of the bearing section plus the connecting rod is greater than the weight of the raised section. The bearing section is located directly below the belt conveyor outlet end, and the raised section is located directly below the probe detection switch. The connecting rod, falling naturally from the belt conveyor outlet end, contacts and presses down on the bearing section. During the fall of the bearing section, it causes the raised section to flip upward. The raised section blocks the probe detection switch, causing the probe detection switch signal to be interrupted. After the connecting rod slides off the bearing section, the raised section automatically falls back to its original position under the action of gravity, and the probe detection switch signal is restored. Each time the detection signal of the probe detection switch disappears, the controller records one count.

[0005] As a preferred embodiment of the present invention, the bending angle of the bending plate is greater than 120 degrees.

[0006] As a preferred embodiment of the present invention, the hinge seat includes: two support rods fixedly connected to the frame, and a bearing seat fixedly connected to the top of the support rods, wherein the flip hinge is rotatably connected to the bearing seats of the two support rods.

[0007] As a preferred embodiment of the present invention, the frame includes a top plate and side support plates located on both sides of the top plate. The side support plates are connected to the belt conveyor frame of the dewatering machine by welding or bolting. A rectangular opening is provided on the top plate, and the pressure-bearing section is located above the rectangular opening.

[0008] As a preferred embodiment of the present invention, a flexible protective layer (rubber layer) is provided on the pressure-bearing section.

[0009] As a preferred embodiment of the present invention, a limiting plate is provided on the side of the frame near the pressure section to limit the pressure section from rising above a set height. The limiting plate is used to control the tilting height of the pressure section.

[0010] Another objective of this invention is to provide a counting method for a dedicated counting device for engine connecting rod dehydration equipment. The method includes: after passing through the dehydrator, the connecting rod is conveyed to the counting station by a belt and falls naturally; during the fall, the large or small end of the connecting rod contacts and lifts a flap; the flap rotates around a shaft and lifts, interrupting the probe detection switch signal and incrementing the counter by 1, meaning the counter count corresponds to the number of times the probe detection switch signal is interrupted during operation; after the connecting rod has completely fallen, the flap automatically returns to its original position under gravity, and the probe detection switch signal is restored; the above actions are repeated when the next connecting rod falls, achieving continuous and accurate counting. No spacing adjustment is required throughout the process, and 100% counting accuracy is maintained even at high speeds.

[0011] The beneficial effects of this invention are as follows: This invention has the advantage of accurate counting, with one trigger per item, no omissions or duplicates, and solves the problem of counting links without intervals.

[0012] This invention has the advantage of high stability, using mechanical triggering and signal detection, and is unaffected by light, dust, or the arrangement of connecting rods.

[0013] This invention has the advantage of high adaptability, and is specifically adapted to the big end / small end structure of connecting rods, without jamming or damaging the workpiece.

[0014] The invention has the advantages of high adaptability, simple structure, low failure rate, and convenient maintenance, making it suitable for long-term use in high-speed dewatering production lines; the data is reliable, and the actual output is statistically analyzed in real time, providing accurate data for production management.

Detailed Implementation

[0017] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

[0018] Example 1

[0019] See Figure 1-4 This embodiment provides a special counting device for engine connecting rod dewatering equipment, including: a frame 1, a flap 2 hinged to the frame 1, a probe bracket 3 mounted on the frame 1 and located above one end of the flap, and a probe detection switch (sensor) 4 mounted on the probe bracket 3. The frame 1 is fixedly connected below the belt conveyor outlet end of the connecting rod via the dewatering machine. Two hinge seats 5 are symmetrically arranged on the frame 1, and a flip hinge 6 is rotatably connected within the two hinge seats 5. The flap 2 consists of an integrally formed pressure section (T-shaped) 201, a raised section (T-shaped) 202, and a bent plate (L-shaped) 203 connecting the pressure section 201 and the raised section 202. The bent plate 203 is L-shaped with a bending angle greater than 120 degrees, and the bending point of the bent plate 203 is fixedly connected to... On the flip hinge 6, the weight of the raised section 202 is greater than the weight of the pressure section 201. The weight of the pressure section 201 plus the connecting rod is greater than the weight of the raised section 202. The pressure section 201 is located directly below the belt conveyor outlet end, and the raised section 202 is located directly below the probe detection switch 4. The connecting rod, which falls naturally from the belt conveyor outlet end, contacts and presses down on the pressure section 201. During the fall of the pressure section 201, it drives the raised section 202 to flip up. The raised section 202 blocks the probe detection switch 4, causing the signal of the probe detection switch 4 to be interrupted. After the connecting rod slides off the pressure section 201, the raised section 202 automatically falls back to its original position under the action of gravity, and the signal of the probe detection switch 4 is restored. Each time the detection signal of the probe detection switch disappears, the controller records one count.

[0020] Furthermore, the hinge seat 5 includes: two support rods 101 fixed to the frame 1, and a bearing seat 102 fixed to the top of the support rods 101. The flip hinge 6 is rotatably connected to the bearing seat 102 of the two support rods 101.

[0021] Furthermore, the frame 1 includes a top plate 103 and side support plates 104 located on both sides of the top plate 103. The side support plates 104 are connected to the belt conveyor frame of the dewatering machine by welding or bolting. A rectangular opening 105 is provided on the top plate 103, and the pressure-bearing section 201 is located above the rectangular opening 105.

[0022] Furthermore, a limiting plate 7 is provided on the side of the frame 1 near the pressure section 201 to limit the pressure section 201 from rising above a set height. The limiting plate 7 is used to control the height of the pressure section 201 to prevent the raised section 202 from hitting the probe detection switch 4.

[0023] Furthermore, a flexible protective layer (rubber layer) is provided on the pressure-bearing section 201, the probe bracket 3 is L-shaped, the vertical section of the probe bracket 3 is fixed to the frame 1, and the probe detection switch 4 is installed on the horizontal section of the probe bracket 3.

[0024] The probe detection switch 4 is model Bi5-M18E-AP6X-H1141, an M18 inductive proximity sensor manufactured by Turck, Germany.

[0025] Working Principle: The mechanism uses the falling posture of the connecting rod to mechanically lift the flap 2, replacing direct photoelectric triggering with physical triggering, thus preventing false counting of the connecting rod without intervals. The flap 2 is mounted on the frame 1 via a rotating hinge 6, located directly below the falling position of the connecting rod. A probe detection switch 4 is fixed above the flap 2 via a probe bracket 3 to detect its position. When the connecting rod falls from the belt, either the large or small end lifts the flap 2, causing it to rise at an angle. The moment the flap 2 rises, the detection signal from the probe detection switch 4 disappears once, and the controller records one count. After the connecting rod leaves, the flap 2 relies on self-realignment, waiting for the next trigger. This mechanical lifting of the flap 2 using the falling posture of the connecting rod replaces direct photoelectric triggering, fundamentally preventing false counting of the connecting rod without intervals.
