[0034] Please also see Figures 1 to 7 A preferred embodiment of the present invention is a queuing circulation cutting band saw car sawing device, which includes a circulation track 1, a feeding car 2 and a sawing mechanism 3.

[0035] The circulation track 1 comprises a feeding track 11 and a transverse track 12 . Two feeding tracks 11 and two transverse tracks 12 are provided. The two feeding tracks 11 are arranged opposite to each other and are respectively located at two ends of the feeding track 11 .

[0036] There is a transverse platform 13 on the transverse track 12, and the transverse platform 13 moves on the transverse track 12 through a first motor 131. A connecting track 14 is provided on the transverse platform 13, and the connecting track 14 can be aligned and spliced ​​with the feeding track 11 by moving the transverse platform 13.

[0037] In this embodiment, four first wheel bodies 132 are provided at the bottom of the transverse moving platform 13, and the first wheel bodies 132 are rotatably connected to the transverse moving platform 13. The two first wheel bodies 132 on both sides are fixedly connected by first transmission rollers 133, and the first motor 131 is transmission-connected to the first transmission rollers 133 so that the transverse moving platform 13 can move on the transverse moving track 12.

[0038] There are three feeding carts 2, and the feeding carts 2 are used for clamping and pushing logs. The feeding carts 2 are driven by a second motor 21. When the connecting track 14 is aligned and spliced ​​with the feeding track 11, the feeding cart 2 can move to the connecting track 14 through the feeding track 11, or move to the feeding track 11 through the connecting track 14, so that the feeding cart 2 can move in a circulation on the circulating track 1.

[0039] The feeding trolley 2 of this embodiment is rotatably provided with four second wheels 202 at the bottom, and the two second wheels 202 on both sides are fixedly connected by second transmission rollers 203. The second motor 21 is transmission-connected with the second transmission rollers 203 so that the feeding trolley 2 can move on the feeding track 11 and the transverse track 12.

[0040] The sawing mechanism 3 is located on one side of one of the feeding tracks 11 , and is used for cutting logs on the feeding vehicle 2 .

[0041] In this embodiment, the feed track 11 close to the sawing mechanism 3 is the first feed track 11a, the feed track 11 away from the sawing mechanism 3 is the second feed track 11b, the transverse track 12 close to the outlet end of the first feed track 11a and close to the inlet end of the second feed track 11b is the first transverse track 12a, and the transverse track 12 close to the inlet end of the first feed track 11a and close to the outlet end of the second feed track 11b is the second transverse track 12b.

[0042] Since the connecting track 14 and the feeding track 11 can be aligned and spliced ​​by moving the transverse platform 13, and the feeding cart 2 can enter the connecting track 14 along the feeding track 11, so that the feeding cart 2 can enter the transverse platform 13, the feeding cart 2 can move in a cycle in the first feeding track 11a, the first transverse track 12a, the second feeding track 11b, and the second transverse track 12b in sequence, and under the action of the sawing mechanism 3, the logs of the feeding cart 2 are cut, thereby forming a closed-loop cyclic cutting method.

[0043] This embodiment provides three feeding carts. When one feeding cart 2 is cutting logs, the previous feeding cart 2 moves along the first transverse track 12a, the second feeding track 11b, and the second transverse track 12b before returning to the first feeding track 11a, while the next feeding cart 2 waits for the cutting of the logs, thereby reducing the idling time of the saw machine and effectively improving the log cutting efficiency.

[0044] In this embodiment, a first limit switch 41 is provided at both ends of each transverse track 12, and the first limit switch 41 is electrically connected to the first motor 131. When the transverse platform 13 triggers any first limit switch 41, the connecting track 14 is aligned and spliced ​​with the feeding track 11.

[0045] Under the action of the first limit switch 41, it can be determined whether the transverse moving platform 12 has moved horizontally into place. When the transverse moving platform 12 triggers any first limit switch 41, it proves that the transverse moving platform 12 has moved horizontally into place. The first limit switch 41 controls the first motor 131 to stop rotating, so that the connecting rail 14 is aligned and spliced ​​with the feeding rail 11, so that the feeding car 2 can enter the connecting rail 14 along the feeding rail 11.

[0046] The transverse moving platform 13 is fixed with a pressure-sensitive switch 42, and second limit switches 43 are provided at both ends of the feeding trolley 2, and the second limit switch 43 is electrically connected to the second motor 21, and the first motor 131 is electrically connected to the pressure-sensitive switch 42. After the feeding trolley 2 leaves the feeding track 11 and enters the connecting track 14, the second limit switch 43 can be abutted and triggered with the pressure-sensitive switch 42, so that the feeding trolley 2 can stop on the transverse moving platform 13. At the same time, the pressure-sensitive switch 42 is triggered, and the first motor 131 is controlled to rotate, so that the transverse moving platform 12 can move laterally.

[0047] Under the action of the second limit switch 43, it is possible to determine whether the feeding cart 2 has completely entered the transverse moving platform 12. When the second limit switch 43 is triggered by the pressure sensing switch 42, it proves that the feeding cart 2 has completely entered the transverse moving platform 12. The second limit switch 43 controls the second motor 21 to stop, and the feeding cart 2 stops on the transverse moving platform 12, so that the transverse moving platform 12 can transport the feeding cart 2.

[0048] In this embodiment, the movement process of the feeding vehicle 2 on the circulating track 1 is as follows: under the action of the second motor 21, the feeding vehicle 2 enters the connecting track 14 through the first feeding track 11a, and when the second limit switch 43 is triggered by the pressure switch 422, the second limit switch 43 controls the second motor 21 to stop. At the same time, the pressure switch 42 controls the first motor 131 to start, and the transverse platform 12 moves on the first transverse track 12a.

[0049] The transverse moving platform 12 triggers the first limit switch 41, and the first limit switch 41 controls the first motor 131 to stop. After the second limit switch 43 is triggered, the second motor 21 is controlled to start after a delay time, and the feeding car 2 enters the second feeding track 11b through the connecting track 14. At the same time, after the first limit switch 41 is triggered, the first motor 131 is controlled to rotate after a delay time, so that the transverse moving platform 12 of the first transverse moving track 12a is reset.

[0050] According to the above steps, the feeding cart 2 enters the transverse platform 13 of the feeding track 11 through the second feeding track 11b, and the transverse platform 13 reaches the first feeding track 11a through the second transverse track 12b, so that the feeding cart 2 returns to the first feeding track 11a again to complete a cycle.

[0051] In this embodiment, an infrared receiver 44 and an external infrared generator 441 are respectively provided at both ends of the feeding cart 2, and the infrared receiver 44 is respectively connected to the external infrared generator 441 and the second motor 21. Under the action of the infrared receiver 44 and the external infrared generator 441, the distance between the two feeding carts 2 can be sensed to control the rotation speed of the second motor 21, thereby preventing the feeding carts 2 from colliding with each other.

[0052] A first trigger member 101 and a second trigger member 102 are provided on the feeding track 11 close to the sawing mechanism 3, and a trigger switch 201 is provided at the bottom of the feeding trolley 2, which is electrically connected to the second motor 21; when the feeding trolley 2 passes the feeding end and the discharging end of the sawing mechanism 3, the trigger switch 201 can be triggered by the first trigger member 101 and the second trigger member 102 in sequence, so that the feeding trolley 2 slows down when passing through the sawing mechanism 3.

[0053] When the trigger switch 201 is triggered by the first trigger member 101, it proves that the feeding cart 2 enters the feeding end of the sawing mechanism 3, and the trigger switch 201 controls the second motor 21 to decelerate so that the logs can be cut at a slow speed; when the trigger switch 201 is triggered by the second trigger member 102, it proves that the log cutting is completed, and the trigger switch 201 controls the second motor 21 to speed up so that the feeding cart 2 can quickly return to the first feeding track 11a to prepare for the next cutting work.

[0054] In this embodiment, the circulating track 1 also includes a guide track 15, which is located on the side of a transverse track 12 facing away from the feeding track 11. When the transverse platform 13 is moved to align and splice the connecting track 14 with the feeding track 11, the guide track 15 is aligned and spliced ​​with the end of the connecting track 14 away from the feeding track 11. A log placement rack 16 is provided on one side of the guide track 15. By controlling the second motor 21, the feeding cart 2 can enter the guide track 15 through the connecting track 14, so that the logs on the log placement rack 16 can be easily installed on the feeding cart 2. Moreover, by controlling the second motor 21, the feeding cart 2 can enter the connecting track 14 through the guide track 15, so that the feeding cart 2 returns to the transverse platform 13.

[0055] In this embodiment, the feeding vehicle 2 includes a base 22 and a clamping mechanism. There are a plurality of clamping mechanisms, and the clamping mechanisms are evenly distributed on one side of the base 22 facing the sawing mechanism 3, and each clamping mechanism includes a fixing frame 5, a threaded rod 51, a connecting block 52 and a clamping member 53.

The threaded rod 51 is driven by the third motor 54, so that the threaded rod 51 can drive the connecting block 52 to move along the axial direction of the threaded rod 51, so as to clamp the log between the clamping arm 531 and the clamping block 532.

[0057] In this embodiment, the third motor 54 is fixed with a first transmission shaft 542 , and the threaded rod 51 is fixed with a second transmission shaft 543 . The first transmission shaft 542 and the second transmission shaft 543 are connected by a transmission belt 541 , so that the third motor 54 can drive the threaded rod 51 to rotate.

[0058] Under the action of the third motor 54, the threaded rod 51 can be driven to rotate. Since the connecting block 52 is slidably connected to the placement groove 501, when the threaded rod 51 rotates, the connecting block 52 can slide in the placement groove 501, so that the clamping arm 531 can be pressed against the log, so that the log is clamped between the clamping arm 531 and the clamping block 532.

[0059] The base 22 includes a fixed seat 221 and a movable seat 222. The movable seat 222 is slidably arranged on the fixed seat 221.

[0064] Under the action of the abutment ring 321 and the clamping bearing 351 , the side of the saw blade 33 facing away from the saw teeth can be abutted to prevent the saw blade 33 from being separated from the transmission disc 32 when cutting logs.

[0065] A discharging rack 6 is fixedly arranged on the side of the frame 31 facing away from the saw teeth. The discharging rack 6 is provided with a discharging trough 61 parallel to the feeding track 11.
