Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of segregation furnace, especially a limiting device for segregation furnace moving trolley. BACKGROUND

[0002] In the segregation purification production process, the segregation furnace moving trolley is mainly used for transporting materials, and the materials are transported into the segregation furnace by the segregation furnace moving trolley for processing, and then the processed materials are transported out of the segregation furnace.

[0003] When the materials need to be sent into the segregation furnace, the operator issues a feeding instruction to the control system of the segregation furnace moving trolley through the operation interface, so that the segregation furnace moving trolley starts from the material storage area and moves along the trolley track to the feeding port of the segregation furnace. Currently, a mechanical limit switch (model LXK3-20S / T) is used to limit the travel of the segregation furnace moving trolley, i.e. a mechanical limit switch is arranged at a position on the trolley track close to the feeding port of the segregation furnace. When the segregation furnace moving trolley contacts the stopper of the mechanical limit switch, the mechanical limit switch feeds back a signal to the control system of the segregation furnace moving trolley, so that the segregation furnace moving trolley stops moving (at this time, the segregation furnace moving trolley is located at the feeding port of the segregation furnace), and the matched unloading device unloads the materials in the segregation furnace moving trolley into the segregation furnace.

[0004] However, since the segregation furnace moving trolley collides with the mechanical limit switch to trigger it, the mechanical limit switch is easily deformed by the external force of the segregation furnace moving trolley. Moreover, since the mechanical limit switch needs to act in each feeding cycle, it is also prone to deformation after long-term use. Therefore, there is a problem of inaccurate positioning of the segregation furnace moving trolley, which affects the segregation purification efficiency. SUMMARY

[0005] The utility model aims to provide a limiting device for segregation furnace moving trolley to solve the problems in the above-mentioned related technologies, so that the segregation furnace moving trolley can be accurately positioned, has a long service life, and improves the segregation purification efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following scheme:

[0007] The utility model provides a limiting device for segregation furnace moving trolley, which comprises a photoelectric switch and a baffle assembly. The photoelectric switch is arranged on the segregation furnace stand and connected with the control system of the segregation furnace moving trolley. The baffle assembly is arranged on the segregation furnace moving trolley. When the segregation furnace moving trolley moves along the track to the position close to the inlet of the segregation furnace, the baffle assembly can trigger the photoelectric switch to stop the movement of the segregation furnace moving trolley and perform material loading and unloading.

[0008] Preferably, the baffle assembly comprises a vertical plate and a horizontal plate, the first end of the vertical plate is used for fixed connection with the moving trolley of the segregation furnace, the second end of the vertical plate is fixedly connected with the first end of the horizontal plate, and the second end of the horizontal plate is used for triggering the photoelectric switch.

[0009] Preferably, the photoelectric switch is a reflection type photoelectric switch.

[0010] Preferably, the photoelectric switch is a diffuse reflection type photoelectric switch.

[0011] Preferably, the photoelectric switch is a mirror reflection type photoelectric switch.

[0012] The utility model discloses relative to relevant technology has obtained following technical effect:

[0013] The utility model discloses a limiting device for segregation furnace moving trolley, including photoelectric switch and baffle assembly, when using, set up photoelectric switch on segregation furnace stand, and connect photoelectric switch with the control system of segregation furnace moving trolley, simultaneously, set up baffle assembly on segregation furnace moving trolley, so that when segregation furnace moving trolley moves to the position close to segregation furnace import along its track, baffle assembly can trigger photoelectric switch, thereby making segregation furnace moving trolley stop moving, and carrying out material loading and unloading.

[0014] Through the device, accurate positioning of the segregation furnace moving trolley is realized, compared with the limiting mode of using the mechanical type travel switch, the limiting mode of using the photoelectric switch is more accurate for positioning of the segregation furnace moving trolley, and the photoelectric switch does not need to contact the segregation furnace moving trolley, can trigger the photoelectric switch to act only by shielding the laser of the photoelectric switch with the baffle assembly, and the service life is long, and the segregation purification efficiency is improved.

[0020] 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 protection scope of the present utility model.

[0021] The purpose of this invention is to provide a limiting device for a segregation furnace moving trolley to solve the problems existing in related technologies, enabling the segregation furnace moving trolley to be accurately positioned, with a long service life, and improving the segregation purification efficiency.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figs. 1-3 As shown, this embodiment provides a limiting device for a segregation furnace moving trolley, including a photoelectric switch 1 and a baffle assembly 2. The photoelectric switch 1 is installed on the segregation furnace column and connected to the control system of the segregation furnace moving trolley 01. The baffle assembly 2 is installed on the segregation furnace moving trolley 01. When the segregation furnace moving trolley 01 moves along its track 02 to a position close to the segregation furnace inlet, the baffle assembly 2 can trigger the photoelectric switch 1 to stop the segregation furnace moving trolley 01 from moving and to load and unload materials.

[0024] In this embodiment, the baffle assembly 2 includes a vertical plate and a horizontal plate. The first end of the vertical plate is fixedly connected to the segregation furnace moving trolley 01, the second end of the vertical plate is fixedly connected to the first end of the horizontal plate, and the second end of the horizontal plate is used to trigger the photoelectric switch 1.

[0025] In this embodiment, the photoelectric switch 1 is preferably a diffuse reflection photoelectric switch. The diffuse reflection photoelectric switch integrates the transmitter and receiver into one unit, which is convenient for installation. When the baffle assembly 2 is detected to pass by, the laser 101 emitted by the transmitter is reflected by the baffle assembly 2 to the receiver, thereby generating a switching signal. Those skilled in the art can also choose a through-beam photoelectric switch or a specular reflection photoelectric switch as needed.

[0026] It should be noted that the connection of the photoelectric switch 1 and the control system of the segregation furnace moving trolley 01 in the embodiment is that the photoelectric switch 1 converts the optical signal into an electrical signal and transmits it into the digital module of the 1769-IM16, and then the programmable controller receives the signal, performs logical operation, and gives the signal to the output module 1769-ow16, and then controls the indication of the signal lamp (i.e. the segregation furnace moving trolley 01 is in place indication), and gives the output module 1769-ow16 a start signal (i.e. the segregation furnace moving trolley 01 loading and unloading action start signal).

[0027] The modification process of using the device to replace the original mechanical travel switch is as follows:

[0028] The original line is not changed, and there are still two lines. The installation position of the previous mechanical travel switch is different from the installation position of the photoelectric switch 1 used in the modification. The photoelectric switch 1 is installed on the segregation furnace stand, and the baffle assembly 2 is installed on the segregation furnace moving trolley 01 to collect signals. Specifically, the center position of the segregation furnace is adjusted to the appropriate position, and then the photoelectric switch 1 and the baffle assembly 2 are adjusted to the appropriate position. When the baffle assembly 2 blocks the laser 101 of the photoelectric switch 1, the signal is connected, and the segregation furnace moving trolley 01 is in place indication light. When the baffle assembly 2 does not block the laser 101 of the photoelectric switch 1, the signal is disconnected, and the segregation furnace moving trolley 01 is in place indication light.

[0029] The device has the following advantages:

[0030] First, the device replaces the original mechanical travel switch with the photoelectric switch 1, and only the baffle assembly 2 blocks the laser 101 of the photoelectric switch 1 to trigger the photoelectric switch 1 to act. There is no deformation due to the external force of the segregation furnace moving trolley 01, which realizes the accurate positioning of the segregation furnace moving trolley 01, ensures the normal work of the segregation furnace moving trolley 01, and improves the segregation purification efficiency.

[0031] Second, the frequency of adjusting the limit by the maintenance worker is reduced, and the frequency of touching the limit by the operator is reduced.

[0032] Third, the service life of the device is long, and the sustainability of the equipment in the production process is increased.

[0033] In summary, for the total deviation of the front limiting position of the segregation furnace, the device is used for photoelectric limiting, fixed-point control, has the advantages of simple installation, sensitive and reliable signal, convenient implementation and the like, completely solves the deviation problem caused by deformation, and further reduces the frequency of adjusting the limit by the maintenance worker, changes the installation position, makes the maintenance condition more reasonable during maintenance, reduces the risk of adjusting the limit, and finally reduces the frequency of intervention by the operator.

[0034] The principle and implementation mode of the present application are described by using specific examples in the present application, and the above embodiment is only used to help understand the method and core idea of the present application; meanwhile, for the general technical personnel in the field, according to the idea of the present application, the specific implementation mode and application range will be changed. In conclusion, the content of the present application should not be understood as a limitation of the present application.
