Embodiment
Illustrate further to illustrate the embodiment for carrying out utility model with reference to the accompanying drawings.
As shown in Figures 1 to 4, a kind of outer formula transfer robot for being applied to the roller Roll Sushi with hollow cylinder, including Base 1, the upper/lower terminal of the base 1 respectively forwardly extends to form upper mounting seat 11 and lower mounting seat 12, and the base 1 is in one " [ " character form structure.Fixed in the upper mounting seat 11 to be equiped with a cylinder 2, the bottom of the lower mounting seat 12, which is fixed, to be equiped with One fix bar 3, the fix bar 3 is used to coordinate in the hollow cylinder of insertion nonwoven cloth rewinder roll Roll Sushi 4, and one is fitted with the cylinder 2 Piston 21, the clutch end of the piston 21 is set with the phase drive connection of a rail support plate 5, and the rail support plate 5 coordinates It is installed in the base 1, the arranged on left and right sides of the rail support plate 5 is respectively symmetrically equiped with a linear bearing 61, a guide rod 62 and a guide rod seat 63, the linear bearing 61 is fixedly mounted on the bottom of the upper mounting seat 11, and the guide rod seat 63 is consolidated Surely the top of the rail support plate 5 is installed in, the top of the guide rod 62, which coordinates, to be installed on the linear bearing 61, described Guide rod seat 63, which coordinates, to be set on the guide rod 61, and the lower end of the guide rod coordinates through the rail support plate.It is straight by setting Bobbin holds 61 and guide rod 62, reduces the angular force of cylinder 1, while adding the motion guide effect of cylinder 1, improves cylinder 1 service life, while by the way that guide rod seat 63 is arranged in rail support plate 5, the jib-length of guide rod 62 is obviously reduced, Further improve the accuracy that guide rod 62 is oriented to.
As shown in Figures 1 to 4, the arranged on left and right sides of the rail support plate 5 is respectively symmetrically equiped with one stroke guider 9, symmetrically arranged first robot support plate 81 and the second robot support plate are equiped with respectively on the stroke guider 9 82, a structure of tabular parallel―ordinal shift 7 being made up of four block size identical connecting plates, the plate are equiped with the fix bar 3 Shape parallel―ordinal shift 7 respectively with the first, second robot support plate(81、82)Connection, and the tabular parallel―ordinal shift 7 Drive the first, second robot support plate(81、82)Open mobile setting to the left and right sides respectively, the tabular four connects Bar 7 drives the first, second robot support plate(81、82)Open mobile setting to the left and right sides respectively, the stroke is led Include the guide rail 91 for being installed in the bottom of rail support plate 5 and the sliding block 92 being slidably installed with the guide rail 91 to device 9, should Sliding block 92 is mutually fixedly connected with setting with the upper end of the first robot support plate 81 or the second robot support plate 82.It is described to lead The guide groove 51 of a linear structure is further opened with rail supporting plate 5, the guide rail 91 is adaptedly installed in the guide groove 51. When the piston 21 of cylinder 2 down pushes away rail support plate 5, first, second robot support plate(81、82)Respectively along leading Bar 62 and guide rail 91, sliding block 92 make planche cross motion, and guide rod 62 and guide rail 91, the effect of sliding block 92 are when first, second machine Tool hand supporting plate(81、82)Planche cross guide effect from when being strutted toward both sides.The effect of tabular parallel―ordinal shift 7 is profit With parallelogram principle, a prime mover i.e. cylinder 2 is simply needed, it is possible to allow tabular parallel four-bar linkage to transmit Power, and make two robot support plates(81、82)Uniform force.Guide rod 62 and guide rail 91, sliding block 92 and tabular double leval jib 7 Multi-guide device, improves equipment life and robust motion.
As shown in Figures 1 to 4, the fix bar 3, the first robot support plate 81 and the second robot support plate 82 The support for forming a three faces positioning takes thing structure, and three face positioning actions can be played in roller 4 vertical-lifting of Roll Sushi, improves crawl fixed Position precision.The curved shape structure of lateral wall of the fix bar 3, the lateral wall of the fix bar 3 can coordinate laminating top to be located at roller volume On the madial wall of the hollow cylinder of thing 4, when overturning runner Roll Sushi 4, using the weight of the complete bearing roller Roll Sushi 4 of fix bar 3, only Have when the inner fiber container of roller Roll Sushi 4 and horizontal plane, the first robot support plate 81, the second robot support plate 82 are just acted as With, so can effective prolonged mechanical hand service life.
As shown in Figures 1 to 4, the lower mounting seat 12 of the base 1 is in " mountain " character form structure, respectively including left, center, right Three installing plates, left and right installing plate is symmetrically installed in the both sides of middle installing plate, and the fix bar 3 is fixed by fixing nut and filled On the middle installing plate for being located at the lower mounting seat 12, spacing between the left and right installing plate and middle installing plate is more than described the The distance moved laterally of one robot support plate 81 and the second robot support plate 82.The stroke of the cylinder piston 21 is big In the first, second robot support plate(81、82)The movement travel of the piston 21 at outer, first, second machinery Hand supporting plate(81、82)Outer distance is more than the interior diameter of the hollow cylinder of roller Roll Sushi 4, it is ensured that the security of manipulator, reliable Property.
The course of work is as follows:
1st, first, second robot support plate when cylinder 2 is not ventilated(81、82)Shrink, first, second robot support plate (81、82)The inner ring of nonwoven cloth rewinder roll Roll Sushi 4 is inserted with fix bar 3.
2nd, cylinder 2 is ventilated toward the direction push piston 21 of rail support plate 5, utilizes guide rod 62 and guide rail 91, the level of sliding block 92 The balance of cross guide effect and tabular parallel―ordinal shift 7 makes first, second robot support plate with stress effect(81、82) Move and opened outside as planche cross along guide rod 62 and guide rail 91, sliding block 92, outer to two robot support plates(81、82)'s Outer surface and the inner peripheral surface extruding of nonwoven cloth rewinder roll Roll Sushi 4 are compressed.First, second robot support plate(81、82), fix bar 3 Three face positioning actions can be played in vertical-lifting, crawl positioning precision is improved, while in vertical-lifting weight, using fix bar 3 carrying weight of object completely, only when nonwoven cloth rewinder roll 4 inner fiber containers of Roll Sushi are perpendicular to the ground, the first robot support plate 81, the Two robot support plates 82 just work, so can effective prolonged mechanical hand life-span.
The utility model by setting tabular parallel―ordinal shift structure, take during thing using be inverted double leval jib, weight weight and Double leval jib opens the extraction and transmission that the characteristics of external diameter is more than paper web internal diameter realizes roller Roll Sushi jointly, and weight weight provides larger The outer tension force of a part, while double leval jib and horizontal sextant angle are smaller during lifting, when object is heavier, robot support plate rolls up nonwoven with roller Outer tension force when cloth inner fiber container is extruded is bigger, and the weight that can be lifted by crane is heavier, and can realize self-locking, reduces the required of cylinder and pushes away Power.The utility model can not only realize the pollution-free discontiguous crawl transmission to non-woven fabrics, and can apply to difference The conveying of specification, the non-woven fabrics of different weight, applicability is more excellent, on the other hand, defeated on this robot manipulator structure more rationally Go out and more stablize, smooth out, more efficient, service life is longer.
Embodiment of the present utility model is above are only, but design concept of the present utility model is not limited merely to This, it is every that the utility model is improved with carrying out unsubstantiality using this design, it should belong to infringement the utility model protection The behavior of scope.
