Detailed implementation manners

[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model and the prior art, the specific implementation manners of the present utility model will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other implementation manners can also be obtained. Additionally, the terms related to directions only represent the relative positional relationships between components, not absolute positional relationships.

[0027] An embodiment of the present utility model provides a protection system for a pile transportation and conveying rail. Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5, mainly including a guardrail arranged outside the conveying track, a plurality of detection units and a controller arranged on the guardrail. The plurality of detection units are electrically connected to the controller, and the detection ranges of the plurality of detection units at least surround the conveying track. The detection units are used to detect whether there is a foreign object breaking into the detection range; the controller is electrically connected to the control system of the conveying track, and the control system is used to control the start and stop of the conveying track.

[0028] In this application, the conveying track can be a track laid on the ground, or a track erected on the ground, or a ground track 3 sunken under the ground. The setting of the ground track 3 can be based on a recessed groove structure opened on the ground, that is, the ground groove 2. The ground track 3 is arranged in the ground groove 2, and part of the conveying surface floats on the ground surface, so as to realize the surface conveying of articles.

[0029] In this application, adding a guardrail outside the conveying track can effectively stop intrusions, but it cannot make remedial actions against intrusion behaviors. Therefore, this application sets a plurality of detection units on the guardrail. The detection units are used to detect whether there is a foreign object intrusion behavior. When an intrusion behavior is detected, the conveying track is stopped urgently to implement remedial actions, so as to avoid the situation from further expanding, reduce property losses, and eliminate potential safety hazards as much as possible.

[0030] At the same time, a reset button can be set. When a temporary stop occurs, the transportation function of the conveying track can only be restored through the reset button.

[0031] In this application, the plurality of detection units can be electrically connected to the controller, and the controller is electrically connected to the control system of the conveying track. The control system is used to control the start and stop of the conveying track; that is, by intervening in the start and stop control of the conveying track through the controller, when an intrusion behavior is detected, the start and stop control of the conveying track can be intervened to make it stop running.

[0032] In a feasible embodiment, please refer to Figure 5 , a cut-off module can be set in the control system. The cut-off module is used to temporarily stop the operation of the conveying track. The cut-off module is electrically connected to the controller, and the plurality of detection units are electrically connected to the controller. The controller judges whether there is an intrusion behavior and issues an instruction to the cut-off module to intervene in the start and stop control of the conveying track.

[0033] Feasibly, an alarm unit can be subordinate to the cut-off module. As Figure 5 shown, when there is an intrusion behavior or during shutdown, an alarm can be issued externally, and other staff can carry out rescue, maintenance, etc. Specifically, the alarm can include beeping, indicator light status change, indicator light flashing, voice broadcast, etc.

[0034] In the embodiment of this application, taking the ground track 3 as an example, please refer to Figure 1, most of the structure of the ground rail 3 is located within the factory area 1. The discharging end extends to the outside of the factory area 1 through the exit 11 of the factory area 1, while the feeding end is located within the factory area 1. A relatively wide groove, namely, the block groove 21, is provided at the feeding end, so that there is a certain space on both sides of the ground rail 3, facilitating the assembly of the ground rail 3; and outside the block groove 21, it can be a straight groove 22. The block groove 21 and the straight groove 22 are in a connected form, constituting the ground groove 2.

[0035] Based on the structure of the groove where the ground rail 3 is located, the guardrails can be divided into straight rail guardrails 4 and end rail guardrails 5. The semi-open end rail guardrail 5 is rectangular, and its open end is docked with the straight rail guardrail 4. The straight rail guardrail 4 is composed of two parallel guardrail structures. Among them, the straight rail guardrail 4 is arranged on both sides of the straight groove 22, and the end rail guardrail 5 surrounds the block groove 21, as Figure 1 shown in.

[0036] The straight rail guardrails 4 are located on both sides of the conveying rail, and the end rail guardrails are located at the feeding end of the conveying rail and are docked with the straight rail guardrails 4, so that the straight rail guardrails 4 cooperate with the end rail guardrails 5 to enclose the conveying rail. The enclosure may not include the discharging end of the conveying rail. The reasonable enclosure range should include the feeding end and most of the structure between the feeding end and the discharging end, but should not completely include the discharging end, so that the products on the rail can complete discharging.

[0037] When setting the detection unit, it can be set based on the guardrail, but the height of the detection unit should be above the guardrail, so as to have the basic conditions for detecting the intrusion behavior across the guardrail.

[0038] Specifically, the detection unit can be a non-contact sensor such as a through-beam photoelectric sensor or a light curtain sensor; it can also be a contact sensor constructed by a cable cooperating with a pressure sensor, a displacement sensor, etc. Exemplarily, the pressure sensor can be fixed at a suitable position and connected to the detection end of the pressure sensor through a cable. The other end of the cable is also fixed to a suitable position. When the cable is touched and tightened to a certain extent and the detection value of the pressure sensor exceeds a certain threshold, it can be considered that there is an intrusion behavior or a dangerous behavior, and the operation of the conveying rail should be stopped in time.

[0039] In a specific embodiment, an assembly pipe 6 can be provided on the guardrail, and one or more detection units are carried in the assembly pipe 6, so that the height of the detection unit is above the height of the guardrail.

[0040] In a feasible embodiment, an extension pipe is provided on the guardrail, and the detection unit is fixed on the extension pipe, so that the height of the detection unit is above the height of the guardrail.

[0041] Based on the above two implementation manners, different forms of detection units are respectively adapted. During specific implementation, selection can be made according to actual requirements. For example, in the first implementation manner, a transmissive photoelectric sensor can be adapted, and in the second manner, a light curtain sensor or a touch sensor can be adapted.

[0042] In the embodiments of the present application, taking the transmissive photoelectric sensor as an example, please refer to Figure 2 , Figure 3 , when multiple detection units are mounted on the assembly pipe 6, according to the direction of the guardrail, the orientations of the multiple detection units are different so as to form an encircling effect on the conveying rail.

[0043] In the present application, the installation position of the assembly pipe 6 can be the same as that of the detection unit. Based on the guardrail form of the ground rail 3, the installation positions of the detection units can be diversified:

[0044] As a feasible installation manner, please refer to Figure 2 , a plurality of detection units are arranged above the two corners at one end of the end rail guardrail 5 away from the straight rail guardrail 4 and the two corners at one end of the straight rail guardrail 4 away from the end rail guardrail 5, so that the detection ranges of the multiple detection units encircle the conveying rail.

[0045] Such as Figure 2 shown, a third detection position 51 and a fourth detection position 52 are respectively arranged at the two corners of the lower boundary of the end rail guardrail 5, and a first detection position 41 and a second detection position 42 are respectively arranged at the two endpoints of the upper boundary of the straight rail guardrail 4. Among them, at least one group of transmissive photoelectric sensors can be paired and arranged between the first detection position 41 and the third detection position 51, and at least one group of transmissive photoelectric sensors can be paired and arranged between the second detection position 42 and the fourth detection position 52, which can meet the basic protection requirements, and the protection range is roughly as shown by the dotted line in Figure 2 ; to enhance the end trigger mechanism, at least one group of transmissive photoelectric sensors can be paired and arranged between the third detection position 51 and the fourth detection position 52. It can be understood that the four detection positions can also be independently arranged outside the guardrail, that is, an assembly pipe 6 is separately arranged outside the guardrail and a detection unit is mounted thereon to form an encircling effect on the conveying rail.

[0046] As another feasible installation manner, please refer to Figure 3 , a plurality of detection units are arranged above the straight rail guardrail 4 and the end rail guardrail 5 along the direction of the guardrail, so that the detection ranges of the multiple detection units encircle the conveying rail. That is, an assembly pipe 6 is arranged at each transfer point, and multiple detection units can be mounted on each assembly pipe 6, and the orientations of the multiple detection units on the same assembly pipe 6 can be different.

[0047] In the embodiments of the present application, the assembly pipe 6 includes a support pipe 61, a middle load pipe 62, a relay pipe 63, and a top load pipe 64. The support pipe 61 is fixedly connected to the guardrail. The basic installation form between each branch pipe is as follows: Plug-in sections are provided at both the upper and lower ends of the middle load pipe 62. A detection unit is built into the middle load pipe 62. The plug-in section at the lower end of the middle load pipe 62 is rotatably inserted into the support pipe 61, and the plug-in section at the upper end of the middle load pipe 62 is rotatably inserted into the lower port of the relay pipe 63. A plug-in section is provided at the lower end of the top load pipe 64. A detection unit is built into the top load pipe 64. The plug-in section at the lower end of the top load pipe 64 is rotatably inserted into the upper port of the relay pipe 63.

[0048] The assembly pipe 6 is preferably installed vertically, standing on the guardrail, and its installation method can be welding, detachable fixed connection, etc.

[0049] In a feasible embodiment, the assembly pipe 6 can delete some branch pipes according to actual needs. For example, the plug-in section at the lower end of the top load pipe 64 is directly rotatably inserted into the support pipe 61, and a detection unit is built into the top load pipe 64.

[0050] It can be understood that the outer diameter of the plug-in section can match the inner diameters of the relay pipe 63 and the support pipe 61. After rotatably inserting, the bodies of the middle load pipe 62 and the top load pipe 64 can be rotated at will to adjust the orientation of the detection unit, so that the opposed photoelectric sensors can be paired.

[0051] Detection ports are provided on the top load pipe 64 and the middle load pipe 62. When the top load pipe 64 and the middle load pipe 62 are connected in series through the relay pipe 63, the detection ports of the top load pipe 64 and the detection ports of the middle load pipe 62 face different directions. The detection ports can specifically be round holes or long strip holes, which can be respectively adapted to opposed photoelectric tubes and light curtain sensors.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
