the specific embodiment
As shown in Figure 1, the printing workpiece clamping and conveying device of the curved surface printing machine in this preferred embodiment, comprises installing plate 1, divided wheel 2, divided wheel power transmission shaft 3, delivery device, printing workpiece detent mechanism.In the present embodiment, printing workpiece is combination cover 17.
Described delivery device is positioned at the place ahead of divided wheel 2 bottoms, and described delivery device comprises cylinder 4 and pushing block 6, and described pushing block 6 is arranged on the axis of the piston 5 of cylinder 4, and the axis of the piston 5 of described cylinder 4 is towards divided wheel 2.
On described installing plate 1, bearing block 7 is installed, self-aligning ball bearing with cylindrical bore 8 is installed in bearing block 7, described divided wheel power transmission shaft 3 front ends are through bearing block 7, described divided wheel 2 is arranged on divided wheel power transmission shaft 3 front ends by Connection Block 10, on divided wheel power transmission shaft 3 between described self-aligning ball bearing with cylindrical bore 8 and Connection Block 10, be arranged with divided wheel spacer 9, the two ends of divided wheel spacer 9 prop up respectively self-aligning ball bearing with cylindrical bore 8 and Connection Block 10, are installed on installing plate 1 divided wheel power transmission shaft 3 is rotating.
Described divided wheel 2 is provided with 6 containing grooves 11, and each containing groove 11 being circumferentially equidistantly arranged in order along divided wheel 2.
Described printing workpiece detent mechanism is arranged on divided wheel power transmission shaft 3, and printing workpiece detent mechanism is positioned on divided wheel 2 trailing flanks.
Described printing workpiece detent mechanism comprises cam 12, 6 folder cover pieces 13, 6 return elements 14, the number of the number of described folder cover piece 13 and containing groove 11 is identical and both are corresponding one by one, the number of described return element 14 is identical with the number that presss from both sides cover piece 13 and both are corresponding one by one, each presss from both sides the cover piece 13 different containing groove 11 of correspondence respectively, each presss from both sides cover piece 13 bottoms the rolling bearing 15 that can roll along the curved surface of cam 12 is installed, each presss from both sides cover piece 13 bottoms and by corresponding return element 14, connects the trailing flank of divided wheel 2, each presss from both sides on the rotating trailing flank that is arranged on divided wheel in cover piece 13 middle parts.Owing to adopting cam 12 mechanisms, therefore can control as required the angle between folder cover piece 13 and corresponding containing groove 11, to catch combination cover 17 or clamping combination cover 17.
The curved surface of described cam 12 is periphery, and cam 12 axis is positioned at the left side, axis of divided wheel power transmission shaft.That is to say, the center of circle of described cam 12 cross sections is not on the axis of divided wheel power transmission shaft, and the center of circle of cam 12 cross sections is positioned at the left side of the axis of divided wheel power transmission shaft, the periphery right-hand member of cam 12 is less than the periphery left end of cam 12 to the distance of divided wheel power transmission shaft to the distance of divided wheel power transmission shaft.
In order to allow folder cover piece 13 can better clamp printing workpiece, described folder cover piece 13 is hook-shaped.Hook-shaped folder cover piece 13 can better be clamped combination cover 17.
Described return element 14 adopts extension spring.
Described printing workpiece detent mechanism can be limited in printing workpiece in containing groove 11, so that divided wheel 2 turns to after suitable angle, then combination cover 17 is emitted.
As shown in Figure 2,3, in described feeding mechanism, the lower cover guide rail that printing workpiece clamping and conveying device is placed on translation mechanism rear end exports 16 belows, and 1 containing groove 11 opening of divided wheel 2 are positioned under lower cover guide rail outlet 16.
1, when the lower cover guide rail outlet 16 next combination cover 17 that falls, this combination cover 17 will just in time fall into above-mentioned containing groove 11, divided wheel 2 rotates after an angle, after under the containing groove 11 adjacent with above-mentioned containing groove 11 is positioned at lower cover guide rail outlet 16, divided wheel 2 stops operating, so that the lower cover guide rail outlet 16 next combination cover 17 that again falls is waited for and caught to the containing groove 11 adjacent with above-mentioned containing groove 11.
2, when divided wheel 2 rotates, because the distance of cam 12 periphery right sides to divided wheel power transmission shaft starts sharply to dwindle, therefore cam 12 peripheries no longer provide support power to the rolling bearing 15 of folder cover piece 13 bottoms, under the pulling force effect of return element 14, the folder cover piece 13 of the above-mentioned containing groove 11 that combination cover 17 is housed diminishes with the angle between corresponding containing groove 11, therefore can clamp combination cover 17, avoid combination cover 17 to drop.
3, when divided wheel 2 turns to the above-mentioned containing groove 11 that combination cover 17 is housed and is positioned at delivery device rear, divided wheel 2 stops operating, and the cylinder 4 of described delivery device drives pushing blocks 6 to move backward, by combination cover 17 from the interior release of containing groove 11.
4, divided wheel 2 is rotated further, the axis of rolling of described folder cover piece 13 bottoms moves to cam 12 periphery left sides, described cam 12 periphery left sides start sharply to increase to the distance of divided wheel power transmission shaft, cam 12 peripheries provide support power to the rolling bearing 15 of folder cover piece 13 bottoms, overcome the pulling force effect of return element 14, allow folder cover piece 13 increase with the angle between corresponding containing groove 11, so as above-mentioned containing groove 11 again move to lower cover guide rail export 16 under time can allow the combination cover 17 falling enter in containing groove 11.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; Be all equivalents of doing according to claim scope of the present utility model, be the utility model claim scope and cover.
