In this embodiment, the second lifting mechanism 3 is similar to the first lifting mechanism 2 in structure, and as can be seen from fig. 2 and 4, the second lifting mechanism 3 includes:

The functions of the components in the second lifting mechanism 3 may be explained correspondingly with reference to the first lifting mechanism 2, and will not be described herein.
In the embodiment of the present application, the driving control of the first push-pull cylinder 21, the second push-pull cylinder 31, the first lifting cylinder 24, and the second lifting cylinder 34 may be performed by a software program or may be manually operated, and this may not be limited, and for example, the time for automatic opening may be set by a preset program, and after the first station is placed for several seconds, the conveying operation from the first station to the second station may be automatically performed, or the conveying operation may be performed after the signal for placing the spline is acquired from the previous station.
And it should be understood that the first push-pull cylinder 21, the second push-pull cylinder 31, the first lifting cylinder 24 and the second lifting cylinder 34 in the present application all have power sources, external power sources or external power sources, or all are provided with electric power by a unified control system.

Further, as can be seen from fig. 5, in a feasible embodiment, a plurality of spline positioning blocks 43 are detachably connected to the spline conveying plate 4 at a side close to the spline placing frame 1, and the fixing manner between the spline positioning blocks and the spline positioning blocks can be various, such as bolting, etc., and the distance between the end surfaces of the spline positioning blocks 43 and the slideway 41 can be adjusted, so that the spline conveyed above the spline conveying plate 4 can be aligned by the spline positioning blocks 43, which is more beneficial to the operation of the next process.
The working process of the conveyor line buffer device provided by the application can be illustrated by fig. 6, wherein five stations (respectively denoted by (1), (2), (3), (4) and (5)) are taken as an example, wherein the first lifting mechanism 2 can bear spline conveying operations at the positions of the stations (1), (2) and (3), and the second lifting mechanism 3 bears spline conveying operations at the positions of the stations (4) and (5). When three sample bars are placed on the sample bar placing frame 1 (the position (a) in fig. 6), the first lifting mechanism 2 needs to be driven to complete the inward conveying operation, the first lifting cylinder 24 drives the first sample bar supporting plate 25 to lift the sample bars (the position (b) in fig. 6), the first push-pull cylinder 21 drives the first moving base 22 to integrally move inwards by a distance of one station, the sample bars are respectively located above the positions (2), (3) and (4) (the position (c) in fig. 6), finally, the first lifting cylinder 24 drives the first sample bar supporting plate 25 to descend and the sample bars are located on the sample bar placing frame (the position (d) in fig. 6), and then the first push-pull cylinder 21 drives the first moving base 22 to integrally move outwards by a distance of one station, so that one conveying operation of the first lifting mechanism 2 is finished.
When the number of splines buffered in the buffer means is the maximum receivable value, the operation of transferring the splines on the spline rack to the spline transfer mechanism needs to be completed by the second lifting mechanism 3. The specific operation process can be illustrated by fig. 7. Also, when five splines are placed on the spline rack (position (a) in fig. 7), the second lifting mechanism 3 needs to be driven to complete the inward transfer operation, firstly the second lifting cylinder 34 drives the second spline support plate 35 to raise and lift the splines (position (b) in fig. 7), then the second push-pull cylinder 31 drives the second moving base 32 to move integrally and inwards by a distance of one station, so that the splines originally located at the positions (4), (5) are located above the positions (c) in fig. 7) respectively, and then the second lifting cylinder 34 drives the second support plate 35 to descend and drop the splines on the spline rack and the spline transfer plate respectively, at this time, because the second push-pull cylinder 31 needs to wait for the next process to push the splines, and the second push-pull cylinder 31 cannot temporarily move and can be moved to the position (c) in fig. 7, and the specific operation process can be performed by the first push-pull cylinder 32 to move the first push-pull cylinder (1) and the first push-pull cylinder (3) and the specific operation can be moved by the first push-pull cylinder (1) and the first push-pull cylinder (3) and the first push cylinder and the specific operation can be moved by the first push cylinder and the first push cylinder (3) and the spline (1) and the spline can be moved by the first and the position and the spline and the second push mechanism and the spline (3 can be moved, the operation of one integral inward transportation is completed. The idle station (1) can continue to carry new splines.
The buffer device provided by the application can effectively solve the problem of spline conveying efficiency, for example, assuming that a spline adopts a conveying chain between a front station and a rear station, the buffer device provided by the application is adopted to move inwards from one station on the spline placing frame for only 5s, so that when the spline needs to be conveyed to the next cutting station, the device provided by the application can convey one sample for 5s, and the prior art can convey only one sample for 30s, so that the efficiency is obviously greatly improved.
Meanwhile, when the operation speed of the last station is higher and the operation of the next station is slower or suddenly slows down, the application can realize the buffer function due to the arrangement of the stations with a plurality of buffer splines, and the problem of spline accumulation is avoided.
According to the technical scheme, the conveyor line buffer device comprises a spline placing frame, a plurality of stations for placing splines in parallel, spline conveying mechanisms, a second lifting mechanism and a lifting mechanism, wherein the stations are arranged above the spline placing frame and are arranged in parallel with the placed splines, the spline conveying mechanisms are arranged on one side of the spline placing frame and comprise spline conveying plates and pushing plates arranged above the spline conveying plates, one side of each spline conveying plate is provided with a slideway, one end of each slideway is provided with a driving device, the pushing plates are connected with the corresponding slideway in a sliding mode, the pushing plates can move along the direction of the spline conveying plates under the driving of the driving devices, the first lifting mechanisms are arranged on two sides of the spline placing frame and are used for lifting the splines to move from one station above the spline placing frame to an adjacent station in the direction of the spline conveying mechanism, and the second lifting mechanisms are arranged on two sides of the spline placing frame and are arranged between the first lifting mechanisms and the spline conveying mechanisms and are used for lifting the splines to move from one station above the spline placing frame to the adjacent station or move from the spline placing frame to the adjacent station. According to the device, the transportation operation of the spline cached on the spline placing rack is realized through the lifting mechanism formed by the two groups of lifting cylinders and the push-pull cylinder, so that when the operation speed difference between the two stations is large, redundant splines can orderly enter the next working procedure, and the stability of the spline in the transportation process can be improved, and the problem of poor spline passing caused by irregular placement is avoided.
