[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the cable reel unloading device 100 according to an embodiment of this application includes two A-shaped brackets coupled in parallel to a pair of parallel guide rails 1. Depending on whether they are directly driven by a motor, the two A-shaped brackets are named the drive-side bracket and the non-drive-side bracket. The drive-side bracket consists of a drive-side lower base 13 coupled to the guide rails 1 and a drive-side upper bracket 11 connected to the drive-side lower base 13. The non-drive-side bracket consists of a non-drive-side lower base 2 coupled to the guide rails 1 and a non-drive-side upper bracket 5 connected to the non-drive-side lower base 2. To accommodate reels 20 of different widths, the drive-side bracket and the non-drive-side bracket can move relative to each other or in opposite directions to clamp the reel 20. Since the reel is not part of this device, it is shown as a dashed line in the figure. The aforementioned relative and opposing movements are achieved through the movement of the clamping screw assembly 8 coupled between the drive-side upper bracket 11 and the non-drive-side upper bracket 5. The relative or opposing movements of the drive-side and non-drive-side brackets can be achieved by driving the screws in the clamping screw assembly 8 to rotate forward and reverse. The screws in the clamping screw assembly 8 can be driven to rotate forward or reverse by the clamping reduction motor 10 coupled to them.

[0024] It should be understood that in the embodiments of this application, the parallel guide rail pair 1 is not necessary, and the cable reel unloading device 100 of this application can be adapted to the parallel guide rail pair that has already been installed.

[0025] A guide unit can be provided between the drive-side bracket and the non-drive-side bracket, for example, between the drive-side upper bracket 11 and the non-drive-side upper bracket 5. The guide unit may include a drive-side telescopic sleeve 9 disposed on the drive-side upper bracket 11 and a non-drive-side telescopic sleeve 7 disposed on the non-drive-side upper bracket 5. The drive-side telescopic sleeve 9 and the non-drive-side telescopic sleeve 7 are coupled together to form a guide unit to guide the relative or opposite movement of the drive-side bracket and the non-drive-side bracket.

[0026] The clamping of the wire coil 20 is achieved by the clamping reduction motor 10 driving the clamping screw set 8, guided by the non-driving side telescopic guide sleeve 7 and the driving side telescopic guide sleeve 9. The opening and closing of the non-driving side upper support 5 and the driving side upper support 11 is achieved by the clamping reduction motor 10 driving the clamping screw set 8, guided by the left and right telescopic guide sleeves 7, 9.

[0027] Similarly, in order to adapt to wire coils 20 of different thicknesses, a height position adjustment unit is provided on the driving side support and the non-driving side support, for example, a first height position adjustment unit is provided on the driving side support, and a second height position adjustment unit is provided on the non-driving side support. The first height position adjustment unit can include a driving side trolley 15 provided on the driving side support, a first lifting screw coupled to the driving side trolley 15, and a first lifting motor coupled to the first lifting screw; correspondingly, the second height position adjustment unit can include a non-driving side trolley 4 provided on the corresponding position of the driving side support, a second lifting screw 3 coupled to the non-driving side trolley 15, and a second lifting motor coupled to the second lifting screw 3. The first height position adjustment unit can be integrally provided on the driving side lower base 13, and the second height position adjustment unit can be integrally provided on the non-driving side lower base 2. It can be noted that the first lifting screw and the second lifting motor cannot be seen because they are blocked, so no reference signs are given.

[0028] The main shafts of the driving side trolley 15 and the non-driving side trolley 4 are provided on the same axis, thereby carrying the wire coil 20. The first lifting screw and the second lifting screw 3 on both sides are driven by the first lifting motor 6 and the second lifting motor, respectively, thereby driving the up-and-down movement of the non-driving side trolley 4 and the driving side trolley 15, achieving the lifting of the wire coil 20 and can be locked at the desired working position. Further, a second limit position sensor can be installed at the two highest and lowest limit positions of the lifting movement, ensuring the reliability of the equipment. And can be locked at the desired working position.

[0029] The main winding reduction motor 12 is coupled to the driving side trolley 15 to provide power to the main shaft of the driving side trolley 15, thereby driving the wire coil 20 to rotate. The main winding reduction motor 12 can be a servo variable frequency AC motor drive, with low maintenance cost, durable and efficient equipment. The wire coil 20 is driven to rotate by the main shaft and the needle carried by the driving side trolley 12.

[0030] In order to adjust the position of the cable laying device 100 as a whole, the lower part of the driving side lower base 13 is provided with walking wheels 18 engaging with the rails of the parallel rail pair 1, the walking wheels 18 are driven by a walking reduction motor 19, so as to drive the driving side lower base 13 to move, thereby driving the whole driving side support to move, and then driving the non-driving side support to move. The non-driving side lower base 2 of the non-driving side support can also be provided with walking wheels engaging with the rails of the parallel rail pair 1. In this way, the position of the cable laying device 100 on the parallel rail pair 1 can be adjusted as a whole. As described above, the walking reduction motor 19 can be switched on and off by using a conventional control mode, and the movement of the whole laying frame 100 is driven by the reciprocating movement of the walking wheels 18 on the rails.

[0031] The driving side support can be provided with an electric control cabinet 16, which can be electrically connected with the first lifting motor 6, the second lifting motor, the clamping reduction motor 10, the main winding reduction motor 12 and the walking reduction motor 19. The actions of the first lifting motor 6, the second lifting motor, the clamping reduction motor 10, the main winding reduction motor 12 and the walking reduction motor 19 are controlled by using a conventional control mode.

[0032] Safety fences can be provided around the cable laying frame device 100, which include a left fence, a right fence, a front fence 17 and a rear fence 14, wherein the left fence and the right fence are installed on the driving side lower base 13 and the non-driving side lower base 2, and the front fence 17 and the rear fence 14 are installed on the ground. Electronic locks and emergency stop buttons can be installed on the front fence and the rear fence, so that the equipment can be stopped nearby in case of special circumstances. When the equipment is maintained, the electronic locks on the front and rear fences are opened, and the equipment is maintained in the equipment. During the opening of the electronic lock, the equipment cannot be started, which ensures the safety of the operation.

[0033] In some embodiments, a PLC controller can be included in the electric control cabinet 16, so as to control the first lifting motor 6, the second lifting motor, the clamping reduction motor 10, the main winding reduction motor 12 and the walking reduction motor 19 according to a preset logic. In addition, the operation of the equipment is facilitated, the electric control cabinet 16 is provided with an emergency stop button and an operation button, and is provided with a wireless remote controller, which can be operated at any position adjacent to the equipment. For example, special circumstances can be handled in time.

[0034] For example, in order to match the field production line speed, the production line main system can send a command to control the PLC closed loop control system in the pay-off device AWB2820, and the frequency converter of the main winding reduction motor 12 in the electric control cabinet 16 is controlled to regulate the rotating speed of the reel 20. For another example, additionally, the PLC closed loop controls the frequency converter of the walking reduction motor 19 to realize the automatic correction function of the center position of the production line, and ensure that the reel 20 is in the center position of the production line. For another example, additionally, in order to prevent the left and right telescopic guide sleeves 7 and 9 from being opened to an unsafe position, a first limit position protection sensor is arranged at the position, a first sensing signal is provided to the PLC to control the emergency stop of the clamping reduction motor 10, thereby ensuring the safe stability of the equipment operation. For another example, by clockwise rotation of the lifting motor 6 on both sides, the lifting lead screw 3 is driven and transmitted to the non-driven side trolley 4 and the driven side trolley 15 to realize upward movement, when the trolley slides up to the limit position, the third limit safety switch sends a signal, and the lifting motor stops rotating. When the lifting motor rotates counterclockwise, the lifting lead screw 3 is driven and transmitted to the non-driven side trolley 4 and the driven side trolley 15 to realize downward movement, when the trolley slides down to the limit position, the fourth limit safety switch sends a signal, and the lifting motor stops rotating. For another example, the non-driven side lower base 2 and the driven side lower base 13 are provided with safety safety switches outside, when moving on the parallel guide rail pair 1, the fifth and sixth limit safety switches send signals when moving to the limit positions at both ends of the guide rail pair 1, and the PLC closed loop control system controls the walking motor 19 to stop moving.

[0035] For another example, the non-driven side lower base 2 and the driven side lower base 13 are provided with safety limit switches outside near the safety fence 14, which also has the safety function of preventing the cable reel pay-off device 100 from tilting. When the production line tension is greater than the limit of the equipment tension, the equipment and the guide rail pair 1 can be disconnected to a certain safety distance, the fifth limit safety switch sends a signal, the PLC closed loop control system controls the feedback signal to the production line main system, and the production line will alarm and stop running.

[0036] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
