[0035] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the specific embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] As Figures 1-4 shown, a track buffer device of the present utility model includes a base 1, two guide rails 2, guide wheels 3, a lifting frame 4, a driving mechanism 5 and a conveyor belt 6.

[0037] Among them, the base 1 is used to carry other components.

[0038] The guide rails 2 are used to carry the guide wheels 3. The two guide rails 2 are relatively fixed on the base 1, parallel and spaced apart, and the length direction of the guide rails 2 is the conveying direction of the workpiece.

[0039] In order to adapt to workpieces of different specifications, the distance between the two guide rails 2 can be adjusted. Preferably, one of the guide rails 2 is fixedly connected to the base 1, and the other guide rail 2 is detachably fixedly connected to the base 1, so that the distance between the two guide rails 2 can match the specifications of the workpiece.

[0040] The guide wheels 3 are used for rolling connection with the workpiece to drive the workpiece to move. The guide wheels 3 are respectively rotatably arranged on the opposite side surfaces of the two guide rails 2, and a plurality of guide wheels 3 are arranged at intervals along the length direction of each guide rail 2; among them, the opposite side surfaces of the two guide rails 2 are the side of one guide rail 2 close to the other guide rail 2.

[0041] The lifting frame 4 is used to drive the workpiece on the guide wheel 3 to separate from the guide wheel 3. The lifting frame 4 includes a lifting rod 41 and a fixing block 42. The lifting rod 41 is slidably arranged on the opposite sides of the two guide rails 2 and is located between two adjacent guide wheels 3; the fixing block 42 is fixedly arranged on the side of the lifting rod 41 away from the guide rail 2. Figure 1 and Figure 2 As shown, in order to allow both the guide wheel 3 and the fixed block 42 to contact the workpiece, the multiple guide wheels 3 and the fixed block 42 connected to the same guide rail 2 are in the same vertical plane, and when the lifting rod 41 slides, the fixed block 42 can move from the bottom of the guide wheel 3 to the top of the guide wheel 3; that is, when the workpiece moves to the position of the fixed block 42 through the guide wheel 3, the fixed block 42 is moved upward by sliding the lifting rod 41, so that the fixed block 42 can be supported against the bottom side of the workpiece, so that the bottom side of the workpiece is separated from the guide wheel 3, and the workpiece is temporarily cached. When the workpiece needs to be transported, the fixed block 42 can be moved downward; during this period, the workpiece will not rub against other components, thereby ensuring the transportation safety of the workpiece.

[0042] like Figure 1 As shown, the lifting frame 4 also includes a connecting frame 43, a ball screw lift 44 and a plurality of sliding shafts 45. The connecting frame 43 is fixedly arranged between the plurality of lifting rods 41, so that the linkage of the plurality of lifting rods 41 can be realized, thereby smoothly lifting or lowering the workpiece.

[0043] The ball screw lift 44 is used to drive the lifting rod 41 to slide automatically. The ball screw lift 44 is fixedly arranged on the base 1, and its output end is fixedly connected to the connecting frame 43. The connecting frame 43 and the lifting rod 41 connected to the connecting frame 43 are driven to slide by the extension and retraction of the output end of the ball screw lift 44; at the same time, the extension and retraction operation of the ball screw lift 44 is more stable, which can improve the operating stability of the cache device; wherein, the principle and structure of the ball screw lift 44 are prior art.

[0044] The sliding shaft 45 is used to improve the sliding stability of the lifting rod 41. Multiple sliding shafts 45 are fixed on the connecting frame 43 and are slidably connected to the guide rail 2 and the base 1 respectively; and in order to shorten the stroke length of the lifting rod 41, it is preferred to make the sliding direction of the sliding shaft 45 and the sliding direction of the lifting rod 41 perpendicular to the horizontal plane, that is, both slide in the vertical direction.

[0045] like Figure 1 and Figure 2As shown, a plurality of lifting rods 41 are arranged on each guide rail 2, and the plurality of lifting rods 41 are arranged in parallel. Arranging a plurality of lifting rods 41 means that there are a plurality of fixing blocks 42 that can simultaneously hold the workpiece, so that the workpiece can move up and down stably. In order to make the spatial layout of this buffer device more stable, it is preferable that the plurality of lifting rods 41 and the plurality of guide wheels 3 connected to the same guide rail 2 are arranged alternately to avoid mutual interference.

[0046] As Figure 1 shown, a plurality of fixing blocks 42 are arranged on each lifting rod 41. The fixing blocks 42 on the plurality of lifting rods 41 correspond one by one, and the corresponding plurality of fixing blocks 42 are located on the same horizontal plane, that is, the fixing blocks 42 are arranged in multiple layers at intervals in the vertical direction, which can increase the amount of workpieces cached by this buffer device.

[0047] Different types of workpieces need to use different types of fixing blocks 42. In order to avoid affecting the accuracy of the installation position when replacing the fixing blocks 42, as Figure 2 shown, a plurality of fixing grooves 401 are formed on the side of the lifting rod 41 away from the guide rail 2. The plurality of fixing grooves 401 on the same lifting rod 41 are equidistant and spaced along the length direction of the guide rail 2, and the fixing blocks 42 are fixedly arranged in the fixing grooves 401, so that different types of fixing blocks 42 can be installed at the same position on the lifting rod 41.

[0048] The driving mechanism 5 is used to drive the guide wheel 3 to rotate automatically. The guide wheel 3 includes a rotating shaft 31 and a feeding wheel 32. The driving mechanism 5 includes a driving motor 51, a driving wheel 52, a driving belt 53 and a pressing wheel 54. As Figure 2 and Figure 3 shown, the rotating shaft 31 is arranged through the guide rail 2 and is rotatably connected thereto, and its rotating shaft is parallel to the horizontal plane; the feeding wheel 32 is fixedly arranged at one end of the rotating shaft 31 and is located between the two guide rails 2. The feeding wheel 32 is used for rolling connection with the workpiece; the driving motor 51 is fixedly arranged on the guide rail 2; the driving wheels 52 are respectively fixedly arranged at one end of the rotating shaft 31 away from the feeding wheel 32 and the output end of the driving motor 51; the driving belt 53 is sleeved outside the plurality of feeding wheels 32; when the driving motor 51 is started, the driving wheel 52 on its output end can be driven to rotate, and then the driving belt 53 is used to drive other driving wheels 52, a plurality of rotating shafts 31 and a plurality of feeding wheels 32 to rotate synchronously, so as to convey the workpiece.

[0049] The pressing wheel 54 is rotatably arranged on the guide rail 2 and abuts against the side of the driving belt 53 away from the driving wheel 52. By using this abutting cooperation, the driving belt 53 is always in a tight state to avoid slipping between the driving belt 53 and the driving wheel 52. In order to improve the uniformity of the pressing of the pressing wheel 54 on the driving belt 53, it is preferable to arrange a pressing wheel 54 between every two adjacent driving wheels 52.

[0050] As the driving belt 53 is used for a longer time, it will have the problem of slackening. The relative position of one of the pressing wheels 54 and the guide rail 2 can be made adjustable, so as to adjust the tension state of the driving belt 53 at any time and keep the driving belt 53 in a tensioned state all the time. As Figure 3 shown, a plurality of holes for installing the pressing wheel 54 can be provided on the guide rail 2, and the pressing wheel 54 is installed in different holes to adjust its relative position with the guide rail 2.

[0051] The conveyor belt 6 is used to drive the workpiece to move. A conveyor belt 6 is provided at each end of each guide rail 2, and the guide wheel 3 is arranged between the two conveyor belts 6 on the same guide rail 2. The conveyor belt 6 is an existing belt conveyor, and its contact surface with the workpiece is larger. Compared with the method of arranging a plurality of guide wheels 3, it can achieve a better conveying effect on the workpiece.

[0052] The working principle of an orbital buffer device of the present utility model is as follows:

[0053] After the workpiece is placed at one end of the guide rail 2, through the conveyance of the conveyor belt 6 and the guide wheel 3, the workpiece can be moved to the middle position of the guide rail 2. Then, the ball screw elevator 44 is started, and it is used to drive the fixed block 42 to move upward, so that the fixed block 42 abuts against and lifts the workpiece to buffer the workpiece on the rail device. When it is necessary to continue conveying the workpiece, the ball screw elevator 44 is controlled again, and it is used to drive the fixed block 42 to move downward, so that the workpiece returns to the top side of the guide wheel 3 again. Then, with the cooperation of the conveyance of the guide wheel 3 and the conveyor belt 6 on the workpiece, the workpiece is conveyed to the other end of the guide rail 2, and the workpiece can enter the next processing procedure.

[0054] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
