Description

Technical Field

[0001] The utility model belongs to the technical field of shuttle vehicles, and in particular relates to a chain debris detection device for a track-type shuttle vehicle. Background Art

[0002] When the rail-type shuttle is moving, debris such as cardboard, film, and cable ties dropped by the manipulator that grabs materials may appear in the positive direction of its movement at any time. Because of the large working range and limited running speed, it is difficult for operators to remove debris in time even if they find it at the first time. In serious cases, the debris will cause irreversible equipment failure to the rail-type shuttle. Defects and shortcomings of the existing situation: Although a debris clearing device has been added to the transmission gear of the rail-type shuttle distance detection encoder, the device can only push the debris away. If the debris is repeatedly squeezed at the end of the rail-type shuttle's operation, it will eventually be rolled under the shuttle, which will greatly increase the maintenance time. In serious cases, it will cause the debris clearing device to deform, which will then affect the normal use of the rail-type shuttle distance detection encoder. Therefore, it is necessary to propose improvements. Utility Model Content

[0003] The technical problem solved by the utility model is as follows: The utility model provides a rail-type shuttle chain debris detection device for the purpose of protecting the shuttle travel detection encoder, eliminating the equipment safety hazards caused by debris such as film and cardboard, reducing the failure rate of the rail-type shuttle, and improving the safety of equipment use.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The signal line of the debris detection sensor is connected to the DI signal point of the remote limit travel switch in the rail shuttle control system.

[0006] As a further limitation of the above scheme, the debris detection sensor adopts a diffuse reflection photoelectric switch with adjustable detection distance.

[0007] To further limit the above scheme, the debris detection sensor is fixed to the position above the travel sprocket and encoder coupling of the rail-type shuttle through a mounting bracket, the mounting bracket is fixedly connected to the frame above the travel sprocket and encoder coupling of the rail-type shuttle, the debris detection sensor is fixed on the mounting bracket, and the detection distance of the diffuse reflection photoelectric switch is debugged on site according to the actual situation on site.

[0008] To further define the above scheme, the mounting bracket is a bracket structure with an L-shaped cross-section, and a horizontal waist-shaped hole and a vertical waist-shaped hole are provided at the upper part of one side plate of the mounting bracket, and the horizontal waist-shaped hole and the vertical waist-shaped hole are fixedly connected to the frame by fixing screws I and II respectively; a threading hole is provided at the lower part of one side plate of the mounting bracket; a sensor mounting hole is provided at the lower part of the other side plate of the mounting bracket, and the debris detection sensor is connected to the sensor mounting hole by screws; the signal line of the debris detection sensor passes through the threading hole and is connected to the DI signal point of the remote limit travel switch in the rail shuttle control system and is connected as one line.

[0009] As a further limitation of the above scheme, a cleaning brush is provided at the front of the travel sprocket and encoder coupling of the rail-type shuttle, and the cleaning brush is fixedly connected to the shuttle sprocket bracket through a bracket.

[0010] The advantages of this utility model compared with the prior art:

[0011] In order to protect the shuttle car's stroke detection encoder, this solution sets a debris detection sensor above the shuttle car's stroke sprocket and encoder coupling, and then uses the DI signal point of the original remote limit travel switch in the shuttle car control system to merge the signal line of the newly added debris detection sensor with it. Utilize the working principle of the original shuttle car: in the automatic state, when the "remote limit travel switch" detects a signal, the shuttle car stops running immediately, and then runs slowly to the origin position at a low speed. This device can not only avoid film, cardboard and other debris from being drawn into the shuttle car in time, but also win precious processing time for on-site operators, fundamentally eliminating the equipment safety hazards caused by film, cardboard and other debris, reducing the failure rate of this type of rail-type shuttle car, improving the safety of use, and achieving the purpose of safe production and quality first.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0017] See also Figure 1-3 , describe the embodiments of the present utility model in detail.

[0018] Example: See Figure 1 and 3 As shown, the rail-type shuttle chain debris detection device includes a debris detection sensor 1, which is fixed above the travel sprocket and encoder coupling of the rail-type shuttle. The signal line of the debris detection sensor 1 is connected to the DI signal point of the remote limit travel switch in the rail-type shuttle control system.

[0019] In this embodiment, in order to achieve the purpose of protecting the shuttle travel detection encoder, a debris detection sensor is set above the shuttle travel sprocket and the encoder coupling, and then the DI signal point of the original remote limit travel switch in the shuttle control system is used to merge the signal line of the newly added debris detection sensor with it. The working principle of the original shuttle is used: in the automatic state, when the diffuse reflection photoelectric switch detects foreign matter, an output signal is output. Because the diffuse reflection photoelectric switch is connected in parallel with the remote limit travel switch signal, the signal is input into the PLC internal program, and then the shuttle stops running immediately, and then runs slowly to the origin position in a low-speed mode. The device can not only avoid the film, cardboard and other debris from being involved in the shuttle in time, but also win precious processing time for the on-site operators, fundamentally eliminating the equipment safety hazards caused by film, cardboard and other debris, reducing the failure rate of this type of rail-type shuttle, improving the safety of use, and achieving the purpose of safe production and quality first.
