[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an automatic reciprocating transport vehicle: an automatic reciprocating transport vehicle includes a frame 1 that moves back and forth on a transport track 7. Infrared anti-collision devices 6 are installed on the lower front and rear middle parts of the frame 1. It also includes two reflectors located at the middle of both ends of the transport track 7, that is, at both ends between two symmetrical transport tracks 7, for example, on objects at both ends of the transport track 7 to prevent collisions. Moreover, the optical axes of the two reflectors are on the same horizontal line as the optical axes of the two infrared anti-collision devices 6. In this way, when the transport vehicle moves close to the reflector, the infrared anti-collision device 6 senses the distance between itself and the reflector and transmits a signal to the control system in a timely manner. The control system receives the signal and controls the power system 2 to stop working to avoid the transport vehicle colliding with objects when it reciprocates on the transport track 7. The infrared anti-collision device 6 can be, but is not limited to, the E3JK-LX5M series infrared anti-collision device.

[0023] The bottom of the frame 1 is equipped with a heavy-duty transmission system that drives it to move on the transport rail 7. The heavy-duty transmission system includes two main drive wheels 3 symmetrically installed on the front side of the bottom of the frame 1 and two driven wheels 32 on the rear side of the bottom of the frame 1. A transmission rod 31 is fixedly connected between the two main drive wheels 3 and between the two driven wheels 32. Both the main drive wheels 3 and the driven wheels 32 are heavy-duty drive wheels.

[0024] The frame 1 is connected to the two transmission rods 31 via bearing seats. The two main transmission wheels 3 are symmetrically arranged at both ends of the transmission rods 31 and located on both sides of the front end of the frame 1. The two driven wheels 32 are symmetrically located on both sides of the rear end of the frame 1. The bottom of the frame 1 is also equipped with a power system 2 for providing power to the heavy-duty transmission system. The power system 2 includes a fixed seat 23 installed on one side of the front end of the frame 1 and a power motor 22 connected to the bottom of the fixed seat 23 via a bracket. The output end of the power motor 22 is connected to a coupling 21, and the output end of the power motor 22 is fixed to one end of one of the transmission rods 31 via the coupling 21, that is, fixed to one end of the transmission rod 31 between the main transmission wheels 3. In addition, the power motor 22 is a geared three-phase asynchronous motor. By controlling the operation of the power motor 22, it drives the transmission rod 31 to rotate via the coupling 21. Thus, the transmission rod 31 drives the two main transmission wheels 3 to move on the transport rail 7, realizing the movement function of the transport vehicle.

[0025] A support base 5 is fixedly installed on the frame 1. A front support plate 51 and a rear support plate 52 are vertically installed at both ends of the support base 5. Multiple placement slots 53 are symmetrically opened at the top of the front support plate 51 and the rear support plate 52. The front support plate 51, the rear support plate 52 and the support base 5 can form a bearing mechanism for placing paper rollers or empty roller shafts. In actual application, the two ends of the paper forming roller can be respectively placed in the placement slots 53 corresponding to the front support plate 51 and the rear support plate 52 to realize the reciprocating conveying of the paper forming roller.

[0026] A control system 4 is installed on the top of the chassis 1. The control system 4 includes an ABB frequency converter, a forward and reverse control relay, an intermediate relay, and a PLC controller. The control system 4 is also connected to a reciprocating switch via wires. Through the cooperation of the ABB frequency converter, the forward and reverse control relay, the intermediate relay, and the PLC controller, the start, stop, and speed regulation of the power motor 22 are controlled. The ABB frequency converter is model ACS355-03E-01A2-4, the forward and reverse control relay is a Schneider Electric small P7 series intermediate relay, and it is powered by DC24V. In addition, according to the automatic reciprocating requirements of the transport vehicle, the operating parameters of the ABB frequency converter can be preset to ensure that the normal, safe and stable operation requirements are met.

[0027] The working principle of this utility model is as follows: This transport vehicle can be used in long-distance round-trip transportation scenarios between factory corridors. In specific use, the two ends of the finished paper roller to be transported can be respectively placed in the corresponding placement slots 53 of the front support plate 51 and the rear support plate 52 to achieve the limiting and fixing of the paper roller. Then, by pressing the "forward" button of the reciprocating switch, the power motor 22 is started and works in the forward direction, which drives the transmission rod 31 to rotate through the coupling 21, and further drives the main transmission wheel 3 to rotate. The main transmission wheel 3 generates frictional driving force between itself and the transport rail 7, so that the transport vehicle can move forward on the transport rail 7.

[0028] During the transport process, the infrared anti-collision device 6 senses the distance between itself and the corresponding reflector. When the set distance is reached, it transmits a signal to the control system 4 in a timely manner. The control system 4 receives the signal and controls the power system 2 to stop working, so as to ensure that the transport vehicle can move to the designated position (i.e. the end point) on the transport track 7 and avoid colliding with objects.

[0029] After the finished paper roll is removed, press the "reverse" button on the reciprocating switch. Then the power motor 22 will start and work in reverse, thus returning the transport vehicle to the initial position. With the help of the infrared anti-collision device 6, the vehicle will automatically and safely stop running.

[0030] It should be noted that the transport vehicle in this design can also be equipped with an automatic braking system to facilitate braking of the main drive wheel 3. The automatic braking system adopts the conventional railcar braking function and can be connected to the control system 4 for control. It adopts existing conventional and mature technology, which will not be described in detail here.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
