Description

Technical Field

[0001] This application relates to the field of through-beam photoelectric switch alignment technology, and in particular to a through-beam photoelectric switch alignment device and its through-beam photoelectric switch assembly. Background Technology

[0002] Through-beam photoelectric switches are typically installed on material production lines to detect the presence of material and provide material signals to control equipment. When the through-beam photoelectric switch is misaligned, it cannot provide an accurate material signal, affecting normal production line operation. Therefore, the alignment of the through-beam photoelectric switch is extremely important. During alignment, if the transmitter and receiver are far apart, the light source will attenuate, making it difficult to determine the light source's landing point visually. Therefore, an alignment device is needed to assist in aligning the through-beam photoelectric switch.

[0003] To achieve alignment of through-beam photoelectric switches, current technology typically involves placing auxiliary light pens and calibration plates on both the transmitter and receiver. When the auxiliary light emitted from both pens falls on the calibration plate on the opposite side, the photoelectric switch is considered calibrated. However, this method still requires visually locating the position of the auxiliary light pens and then making multiple empirical adjustments based on that position. Clearly, this method still consumes a significant amount of time. Utility Model Content

[0004] Therefore, it is necessary to provide an efficient and rapid through-beam photoelectric switch alignment device and its through-beam photoelectric switch assembly.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A through-beam photoelectric switch alignment device is provided for aligning and adjusting a through-beam photoelectric switch. The through-beam photoelectric switch includes a main body, a first transmitter, and a first receiver. The first transmitter is mounted on one side of the main body, and the first receiver is located at a first target position to receive light emitted by the first transmitter. The through-beam photoelectric switch alignment device includes:

[0007] A housing for detachable mounting to the main body;

[0008] The beam-emitting assembly includes a second transmitter and a second receiver. The second transmitter is installed inside the housing, and the emitting end of the second transmitter is located on the side of the housing and is used to emit auxiliary light. The second transmitter and the first transmitter are located on the same side of the main body. The second receiver is installed at a second target position and is used to receive the auxiliary light emitted by the second transmitter.

[0009] An angle detection element is installed on the housing and is used to detect the angle between the main body and the horizontal plane.

[0010] Understandably, this application, by setting up an angle detection component and a through-beam assembly, allows for rapid alignment of the through-beam photoelectric switch when the switch needs to be aligned. The angle detection component measures the angle between the main body and the horizontal plane, and based on the angle deviation, quickly adjusts the angle between the main body and the horizontal plane to the angle required for alignment. The through-beam assembly then assists in the alignment process. This achieves rapid alignment of the through-beam photoelectric switch and effectively improves alignment efficiency.

[0011] In one embodiment, the housing is provided with a positioning plate and a clamping member, the positioning plate being used to fit against the side of the main body, and the clamping member being used to clamp the main body.

[0012] It is understandable that by setting up a positioning plate and clamping parts, and by using the positioning plate to fit against the side of the main body, the installation position of the shell on the main body can be positioned, so that the shell can be accurately installed on the main body. Then, the clamping parts are used to hold it on the main body, thereby realizing the installation of the shell on the main body.

[0013] In one embodiment, the positioning plate includes a first panel and a second panel, which are connected to each other and angled together, and are used to fit different sides of the body.

[0014] Understandably, by utilizing the fit between the first and second panels and different sides of the main body, alignment can be achieved from different directions, allowing the housing to be more stably positioned and installed on the main body.

[0015] In one embodiment, the clamping member includes a pull rod and a clamping block, the pull rod being telescopically mounted on the housing, and the clamping block being mounted on the pull rod and capable of forming a clamping space between itself and the housing to clamp the main body.

[0016] In one embodiment, the first receiver and the second receiver are configured as the same receiver;

[0017] The through-beam photoelectric switch alignment device also includes a light guide tube, one end of which is covered by the second emitter, and the other end is provided with a light outlet; wherein, the auxiliary light emitted from the light outlet coincides with the light emitted from the first emitter.

[0018] Understandably, by setting up a light guide tube, the auxiliary light emitted by the second transmitter is made to exit through the light outlet and coincide with the light emitted by the first transmitter. In this way, the second and first transmitters can share a single receiver, which not only reduces the installation of the second receiver and saves costs, but also ensures that during adjustment, since the same receiver is used, after adjustment, when the light emitted by the second transmitter is received by the same receiver, the light emitted by the first transmitter will also be received by the same receiver, thus completing the alignment process.

[0019] In one embodiment, the inner wall of the light guide tube is set as a mirror, and the light entering the light guide tube is reflected by the mirror and then emitted from the light outlet.

[0020] In one embodiment, the inner wall of the light guide tube includes a first reflective mirror and a second reflective mirror, the first reflective mirror and the second reflective mirror are parallel and opposite to each other, and the light incident angle of the first reflective mirror and the second reflective mirror is set to 45 degrees.

[0021] In one embodiment, the angle detection element is configured as a universal level or an angle sensor.

[0022] In one embodiment, the housing has a receiving cavity, and the inside of the receiving cavity has a positioning plane. The positioning plane is perpendicular to the side of the housing where the transmitting end is located, and the second transmitter is mounted on the positioning plane.

[0023] This application also provides the following technical solutions:

[0024] A through-beam photoelectric switch assembly includes a through-beam photoelectric switch and a through-beam photoelectric switch alignment device as described in any of the above embodiments.

[0025] The main body and the shell are in surface-to-surface contact.

[0026] Compared with existing technologies, the through-beam photoelectric switch alignment device, by setting up an angle detection element and a through-beam assembly, allows for rapid alignment of the through-beam photoelectric switch when alignment is required. The angle detection element measures the angle between the main body and the horizontal plane, and based on the angle deviation, quickly adjusts the angle between the main body and the horizontal plane to the angle needed for alignment. Then, the through-beam assembly assists in alignment. This achieves rapid alignment of the through-beam photoelectric switch and effectively improves alignment efficiency.

[0040] Numerous through-beam photoelectric switches 201 are installed on equipment such as storage cabinets, warehouses, and feeders in cigarette production lines to detect tobacco materials and provide material signals for control equipment. During actual tobacco production, equipment maintenance, and repair, misalignment of these photoelectric switches frequently occurs, affecting normal production and requiring timely maintenance. Traditionally, maintenance personnel rely on visual inspection to determine the alignment of the transmitter and receiver of the through-beam photoelectric switch 201, using the receiver's on signal as an alignment marker. When the transmitter and receiver are far apart, light attenuation makes it difficult to visually determine the light source's landing point. Existing methods also include auxiliary light pens and calibration plates on both the transmitter and receiver; when the auxiliary light emitted from both pens falls on the opposite calibration plate, the through-beam photoelectric switch is considered calibrated. However, both methods suffer from time-consuming alignment and low efficiency.

[0041] For more information on this, please refer to [link / reference]. Figures 1 to 4 This application provides a through-beam photoelectric switch alignment device 100, which is used for rapid alignment and adjustment of a through-beam photoelectric switch 201. The through-beam photoelectric switch 201 is generally installed on tobacco conveying equipment during cigarette production (e.g., at the inlet of the tobacco box, at a critical position in the tobacco conveying pipe, at the inlet of the packaging machine, etc.) and can be used to detect whether there are any abnormalities in the cigarette production line. The through-beam photoelectric switch 201 includes a main body 202, a first transmitter 203, and a first receiver (not shown). The main body 202 is rotatably connected to the desired installation position, and the tilt angle of the main body 202 relative to the horizontal plane is fixed by fixing bolts. When alignment is required, the tilt angle of the main body 202 relative to the horizontal plane can be adjusted by loosening the fixing bolts. The first transmitter 203 is installed on one side of the main body 202, and the first receiver is located at a first target position to receive the light emitted by the first transmitter 203. Here, the first target position refers to the other side of the tobacco conveying equipment opposite the installation position of the main body 202.

[0042] Specifically, the through-beam photoelectric switch alignment device 100 includes a housing 10, a through-beam assembly 20, and an angle detection element 30. The housing 10 is detachably mounted on the main body 202. The through-beam assembly 20 includes a second transmitter 21 and a second receiver (not shown). The second transmitter 21 is mounted inside the housing 10, and its emitting end 211 is located on the side of the housing 10 and is used to emit auxiliary light. The second transmitter 21 and the first transmitter 203 are located on the same side of the main body 202. The second receiver is mounted at a second target position to receive the auxiliary light emitted by the second transmitter 21. The angle detection element 30 is mounted on the housing 10 to detect the angle between the main body 202 and the horizontal plane. Here, the second target position refers to the position of the auxiliary light emitted by the second transmitter 21 when the first receiver can receive the light emitted by the first transmitter 203.

[0043] It should be explained that in the prior art, the position of the auxiliary light emitted by the through-beam photoelectric switch alignment device 100 needs to be observed with the naked eye first, and then adjustments are made according to the position of the auxiliary light. When the through-beam photoelectric switch 201 is tilted at a large angle, the process of observing the position of the auxiliary light with the naked eye will take a long time. This application, by setting an angle detection element 30 and a through-beam assembly 20, when it is necessary to align the through-beam photoelectric switch 201, uses the angle detection element 30 to detect the angle between the main body 202 and the horizontal plane, and thus, based on the angle deviation value, can quickly adjust the angle between the main body and the horizontal plane to the required value. The angle of the through-beam photoelectric switch 201 during alignment is determined, and then the through-beam assembly 20 is used for auxiliary alignment. During this process, the angle of the main body 202 relative to the horizontal plane is first adjusted by the angle detection component 30. After the adjustment is completed, the position of the auxiliary light is located near the second receiver, which can quickly find the position of the auxiliary light for auxiliary alignment without having to observe the position of the auxiliary light with the naked eye at the beginning. Therefore, when the tilt angle of the through-beam photoelectric switch 201 is large, the time spent finding the auxiliary light is reduced, and the rapid alignment of the through-beam photoelectric switch 201 is achieved, thereby improving the alignment efficiency of the through-beam photoelectric switch 201.

[0044] In one embodiment, the housing 10 is provided with a positioning plate 11 and a clamping member 12. The positioning plate 11 is used to fit against the side of the main body 202, and the clamping member 12 is used to clamp the main body 202. Thus, by providing the positioning plate 11 and the clamping member 12, the installation position of the housing 10 on the main body 202 can be positioned by the positioning plate 11 fitting against the side of the main body 202, so that the housing 10 is accurately installed on the main body 202, and then the clamping member 12 is used to clamp the housing 10 on the main body 202, thereby realizing the installation of the housing 10 on the main body 202.

[0045] like Figure 1 and Figure 4As shown, the positioning plate 11 includes a first panel 111 and a second panel 112. The first panel 111 and the second panel 112 are connected to each other and set at an angle. The first panel 111 and the second panel 112 are used to fit different sides of the main body 202. By setting the positioning plate 11 to include the first panel 111 and the second panel 112, and by utilizing the fit between the first panel 111 and the second panel 112 and different sides of the main body 202, alignment can be performed from different directions, allowing the housing 10 to be more stably positioned and installed on the main body 202. This enables the through-beam photoelectric switch alignment device 100 to be quickly installed and positioned on the through-beam photoelectric switch 201. Here, the included angle between the first panel 111 and the second panel 112 can be 70 degrees, 90 degrees, 110 degrees, etc., and is selected accordingly based on the included angle formed by the sides of the main body 202 during use.

[0046] In this embodiment, the main body 202 is square in shape, and the intersecting sides of the main body 202 are arranged vertically. Therefore, the first panel 111 and the second panel 112 are also arranged vertically and can fit together with the two sides of the main body 202.

[0047] like Figure 1 As shown, the clamping member 12 includes a pull rod 121 and a clamping block 122. The pull rod 121 is telescopically mounted on the housing 10, and the clamping block 122 is mounted on the pull rod 121, forming a clamping space 123 between the clamping member 121 and the housing 10 to clamp the main body 202. The clamping member 12 is connected to the housing 10 via the pull rod 121, and together with the pull rod 121 and the housing 10, forms the clamping space 123, which can clamp the housing 10 onto the main body 202. By configuring the pull rod 121 as a telescopic structure, the pull rod 121 can be housed inside the housing 10 when not in use. This saves space occupied by the through-beam photoelectric switch alignment device 100 when housed, and also prevents the pull rod 121 from being deformed due to collision when extended.

[0048] Here, the number of pull rods 121 can be configured to be multiple, such as two, three, four, etc. By setting multiple pull rods 121, the clamping block 122 is connected to the housing 10 through multiple pull rods 121, which enables the clamping block 122 and the housing 10 to be stably connected and their relative positions to remain unchanged, so that the housing 10 can be stably clamped on the main body 202 through the clamping block 122.

[0049] In this embodiment, the number of pull rods 121 is configured as two. The two pull rods 121 can not only keep the clamping block 122 and the housing 10 stably connected, but also have a lower manufacturing cost.

[0050] Furthermore, the clamping member 12 also includes a spring (not shown), which is installed inside the housing 10. One end of the spring is limited in the housing 10, and the other end is limited in the pull rod 121. When the pull rod 121 extends, the spring is stretched and provides a locking force for the clamping block 122. After the abutment between the clamping block 122 and the main body 202 is released, the pull rod 121 retracts and returns to its original position under the action of the spring.

[0051] like Figure 3 As shown, a receiving cavity 13 is provided inside the housing 10, and a positioning plane 131 is provided inside the receiving cavity 13. The positioning plane 131 is perpendicular to the side of the housing 10 where the transmitting end 211 is provided, and the second transmitter 21 is mounted on the positioning plane 131. The transmitting end 211 is the end of the second transmitter 21 that emits light.

[0052] In one embodiment, the angle detection element 30 is configured as a universal level or an angle sensor.

[0053] In this embodiment, the angle detection element 30 is set as a universal level, and the universal level is set on the top plane 14 of the housing 10.

[0054] In one embodiment, the first receiver and the second receiver are configured as the same receiver. The through-beam photoelectric switch alignment device 100 also includes a light guide tube 40, one end of which covers the second transmitter 21, and the other end is provided with a light exit hole 41. The auxiliary light emitted from the light exit hole 41 coincides with the light emitted from the first transmitter 203. Thus, by providing the light guide tube 40, the auxiliary light emitted by the second transmitter 21 is emitted from the light exit hole 41 and coincides with the light emitted from the first transmitter 203, allowing the first receiver and the second receiver to be configured as the same receiver. This not only reduces the installation of the second receiver and saves costs, but also, during adjustment, since the same receiver is used, after adjustment, when the light emitted by the second transmitter 21 is received by this receiver, the light emitted by the first transmitter 203 will also be received by the same receiver, thereby completing the alignment. The absence of a second receiver during alignment makes the installation of the through-beam photoelectric switch alignment device 100 much simpler.

[0055] like Figure 2 and Figure 3 As shown, the inner wall of the light guide tube 40 is set as a mirror. The auxiliary light entering the light guide tube 40 is reflected by the mirror and then emitted from the light outlet 41.

[0056] In one embodiment, the inner wall of the light guide tube 40 includes a first reflecting mirror 42 and a second reflecting mirror 43. The first reflecting mirror 42 and the second reflecting mirror 43 are parallel and opposite to each other, and the light incident angle of the first reflecting mirror 42 and the second reflecting mirror 43 is set to 45 degrees.

[0057] like Figure 3 As shown, the through-beam photoelectric switch alignment device 100 also includes a battery pack 50, which is disposed in the accommodating cavity 13 and electrically connected to the first transmitter 203 for supplying power to the first transmitter 203.

[0058] In one embodiment, the through-beam photoelectric switch alignment device 100 further includes a button 60, which is disposed on the housing 10 and electrically connected to the first transmitter 203 for controlling the opening and closing of the first transmitter 203.

[0059] This application also provides the following technical solutions:

[0060] A through-beam photoelectric switch assembly 200 includes a through-beam photoelectric switch 201 and a through-beam photoelectric switch alignment device 100 as described in any of the above embodiments; wherein the main body 202 and the housing 10 are in surface-to-surface contact.

[0061] The adjustment method for the through-beam photoelectric switch alignment device 100 is as follows:

[0062] 1. Pull out the lever 121 of the clamping member 12 so that the housing 10 is located in the clamping space 123;

[0063] 2. Adjust the positioning plate 11 so that its first panel 111 is in contact with the second panel 112 and the two sides of the main body 202;

[0064] 3. Press button 60, and the second transmitter 21 emits an auxiliary light beam. This auxiliary light beam is guided by the light guide tube 40 to coincide with the light beam of the through-beam photoelectric switch 201.

[0065] 4. Loosen the fixing bolts of the through-beam photoelectric switch 201, adjust the through-beam photoelectric switch 201 according to the universal level until the bubble of the universal level is in the center of the level, and adjust the through-beam photoelectric switch 201 according to the auxiliary light emitted by the second transmitter 21. When the first receiver receives the auxiliary light emitted by the second transmitter 21, turn on the switch of the first transmitter 203 and confirm that the first receiver has received the signal and the indicator light is lit.

[0066] 5. Tighten the fixing bolts of the through-beam photoelectric switch 201, turn off the second transmitter 21, and remove the through-beam photoelectric switch alignment device 100.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
