Description

Technical Field

[0001] The present invention relates to an automatic coil loading and wire paying-off device, and particularly to an automatic coil loading and wire paying-off device based on an AGV intelligent vehicle. Background Art

[0002] A cable mainly consists of a conductor, an insulating sheath, and an insulating outer covering. In warehousing, the weight of the entire cable is very large, which includes the weight of the conductor metal, the insulating sheath, and the insulating outer covering, as well as the weight of the tape, the winding amount, and the braiding amount. When the cable reel is warehoused, the current prior art is to push it into the wire paying-off rack manually. Such a method not only consumes a lot of manpower, but also has low work efficiency and low work safety due to manual operation, making it difficult to improve the warehousing efficiency.

[0003] For example, the patent with the authorization announcement number CN207046570U discloses a cable coil loading auxiliary vehicle for warehousing, including two parallel support beams and an adjusting cross beam connecting the two parallel support beams. One of the support beams is a driving walking beam, with pulleys installed below it, and a guide rail for controlling its walking direction is provided on the ground, and a first motor is also installed on this support beam; the other is a driven walking beam, with steerable pulleys installed below it: the adjusting cross beam is a telescopic structure, and a second motor is fixed on it. Thus, the traditional manual coil loading operation mode in this industry is changed, which not only greatly saves human resources, but also has high mechanization degree, high operation safety degree, and high coil loading efficiency due to less manual participation. Although there are many advantages in the above technology, the inventor found that there are still defects: the positioning accuracy before the coil assembly cannot be guaranteed, and the loading and unloading operations of the coil are not easy. In view of this, the present invention designs an automatic coil loading and wire paying-off device based on an AGV intelligent vehicle. Summary of the Invention

The driving gear meshes with the two driven gears. When the first stepping motor works, it can drive the two driven gears to rotate synchronously through the rotation of the driving gear, so that the two bidirectional lead screws rotate. Then, the two first linear sliders in the same moving rail can move towards each other or away from each other, and under the action of the X - shaped telescopic frame, the height of the transport tray can be adjusted. On the one hand, it is convenient to unload goods onto the front fork of the trolley for use. On the other hand, the transport tray can load spool bodies of different heights, improving the adaptability.

[0017] Preferably, a mounting slot is provided on a side of the front fork of the trolley away from the AGV trolley body, and a laser rangefinder is installed in the mounting slot.

[0018] Preferably, a PLC controller is fixedly installed on the front side of the AGV trolley body, and the laser rangefinder and the second electric telescopic rod are electrically connected to the PLC controller. When loading the reel, the AGV trolley body moves the reel body to the assembly position of the pay-off device, that is, the front fork of the trolley faces the pay-off device, and the laser rangefinder thereon detects the distance value between the AGV trolley body and the pay-off device, and the distance value is the preset value of the assembly position. The laser rangefinder transmits a signal to the PCL controller, so that the PLC controller controls the second electric telescopic rod to start, and the second electric telescopic rod drives the supporting block to move upward, that is, the reel body is moved upward until the mounting hole of the reel body is aligned with the pay-off shaft of the pay-off device. At this time, the upper end of the supporting block moves out of the recessed mouth, thereby automatically releasing the movement restriction of the reel body, and then the AGV trolley body continues to move forward for a displacement, so that the reel body can be automatically assembled on the pay-off shaft.

[0019] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) In this application, the wire reel body is placed on the supporting block on the front fork of the trolley, and at this time the top surface of the supporting block is lower than the opening of the recessed mouth, so that the wire reel body can be placed stably, which ensures the accuracy of subsequent loading. The AGV trolley body can transport the wire reel body to reduce the difficulty of transporting the wire reel body.

[0021] (2) In the present application, when loading the reel, the AGV trolley body moves with the reel body to the assembly position of the pay-off device, that is, the front fork of the trolley faces the pay-off device, and the laser rangefinder on it detects the distance value between the AGV trolley body and the pay-off device, and the distance value is the preset value of the assembly position. The laser rangefinder transmits the signal to the PCL controller, so that the PLC controller controls the second electric telescopic rod to start, and the second electric telescopic rod drives the supporting block to move upward, that is, the reel body is moved upward until the mounting hole of the reel body is aligned with the pay-off shaft of the pay-off device. At this time, the upper end of the supporting block moves out of the recessed mouth, thereby automatically releasing the movement restriction of the reel body, and then the AGV trolley body continues to move forward for a displacement, so that the reel body can be automatically assembled on the pay-off shaft.

[0022] (3) In the present application, the transport disc can also carry the wire reel body, so that the AGV trolley body can transport at least two wire reel bodies at a time to speed up the loading efficiency. The wire reel body is placed between the linear push plate and the anti-slip baffle in the placement slot. The anti-slip baffle blocks the wire reel body to prevent it from moving. When unloading, the first electric telescopic rod works to move the anti-slip baffle downward in the baffle sliding hole until the anti-slip baffle removes the obstruction to the wire reel body so that the wire reel can be taken from the placement slot.

[0023] (4) In this application, the first stepping motor operates. It can drive two driven gears to rotate synchronously through the rotation of the driving gear, causing the two bidirectional lead screws to rotate. Subsequently, the two first linear sliders within the same moving rail can move towards or away from each other. Under the movement of the X-shaped telescopic frame, the height of the transport tray can be adjusted. On the one hand, it is convenient to unload goods onto the front fork of the trolley for use. On the other hand, the transport tray can load wire spool bodies of different heights, improving the adaptability. Description of the Drawings
