Detailed description of the invention
Below contrast accompanying drawing and combine preferred embodiment the utility model is described in further detail.
The utility model provides a kind of cylindrical articles feedway, and in a preferred embodiment, as shown in figures 1-4, it is located on bench board 8, comprises loader 1, feeding-passage 2, passage opening and closing part 3, distributing buffer pond 4, runner 5 and block 6; Described feeding-passage 2 is positioned at the front side in described distributing buffer pond 4, described passage opening and closing part 3 coordinates with described feeding-passage 2, be used to open or close described feeding-passage 2, the entrance of described feeding-passage 2 is connected with the outlet of described loader 1, and the outlet of described feeding-passage 2 is docked with described distributing buffer pond 4; Described runner 5 is arranged on the rear side in described distributing buffer pond 4 and is communicated with described distributing buffer pond 4.
The front side in described distributing buffer pond 4, left side and right side respectively correspondence be provided with before blowing nozzle 41, left blowing nozzle 42 and right blowing nozzle 43, described front blowing nozzle 41 is relative with described runner 5, is also provided with pressure release passage 44 on described front blowing nozzle 41 side of the front side in described distributing buffer pond 4; Described block 6 is arranged on the end of described runner 5, and described block 6 is provided with bleed passage 61, and the size of described front blowing nozzle 41, left blowing nozzle 42, right blowing nozzle 43, pressure release passage 44 and bleed passage 61 is less than the size of described cylindrical articles.
Front blowing nozzle 41, left blowing nozzle 42 and right blowing nozzle 43 are respectively by air inlet pipe (not shown) connecting fan (not shown), the size of front blowing nozzle, left blowing nozzle, right blowing nozzle, pressure release passage and bleed passage is less than the size of cylindrical articles, the size of distributing buffer pond and runner can customize according to the size of cylindrical articles, ensures that cylindrical articles can move freely and rolling do not occur and laminates in distributing buffer pond and runner.Pressure release passage can adopt wide and flat structure, to ensure that air-flow can pass through but cylindrical articles cannot pass through.Bleed passage 61 on block 6 between the height and the height of described cylindrical articles of the center of gravity of described cylindrical articles, can ensure that air-flow passes through and cylindrical articles accurately stops from the height of described runner.
The cylindrical articles entered in runner directly can be captured by manipulator, in this preferred embodiment, also comprises ejecting mechanism 7, and ejecting mechanism 7 is arranged on the below of the end of described runner 5, captures for manipulator to be ejected by cylindrical articles.
In the present embodiment, front blowing nozzle 41, left blowing nozzle 42 and right blowing nozzle 43 are all in horn-like, the larger one end of opening is towards described distributing buffer pond 4, and described front blowing nozzle and pressure release passage all have two at least, and described front blowing nozzle and described pressure release passage are alternately uniformly distributed; Described runner has two at least, the width of described runner and the size of described cylindrical articles suitable.In this example, have 10 runners, left blowing nozzle 42 and each two of right blowing nozzle 43, front blowing nozzle has four, and bleed passage has six, is alternately uniformly distributed with front blowing nozzle.
Passage opening and closing part 3 can be cylinder, also can be electric solenoid valve, can as long as mechanism that feeding-passage opens or closes automatically can be realized, in this example, passage opening and closing part 3 is the cylinder of up-and-down movement, cylinder is arranged on the below of described feeding-passage 2, by the up-and-down movement of the piston of cylinder, can close and open feeding-passage, closing passage in the distribution of cylindrical articles is carried out in air blowing, prevent the cylindrical articles in distributing buffer pond from flowing out from feeding-passage, when blowing stopping, open feeding-passage, by loader, cylindrical articles is sent into distributing buffer pond.
Described loader 1 is vibrating disk (certainly shaking regulating control other being also provided with of vibrating disk), transparent cover plate 10 is also provided with above distributing buffer pond 4 and runner 5, transparent cover plate 10 can also be equipped with sensor 11, it is optical fiber transducer in this example, there are ten, whether all corresponding sensor 11 in top of every bar runner 5, have cylindrical articles to eject in order to detect, so that and manipulator on-line working.
Cylindrical articles feedway of the present utility model is particularly useful for the automatic supply of the cylindrical articles of length within diameter twice (as nut), now further illustrates working process for nut:
Nut 9 is arranged by vibrating disk and divides and enters distributing buffer pond by feeding-passage backward, then to be blown in each runner by nut with pressure air and to go, and carries out proper alignment.The pressure of pressure air used is at below 0.6MPa, according to the size of nut and the size of cylindrical articles feedway, the pressure of pressure air can be regulated in suitable size by pressure-modulation valve, rolling does not occur to ensure nut can move freely in distributing buffer pond and runner and laminates.
Comparatively desirably, when the work of start, the nut that vibrating disk conveying exceedes distributing buffer tankage 1/3 quantity enters distributing buffer pond, left blowing nozzle and right blowing nozzle alternately can be blown and be made nut be dispersed in distributing buffer pond, then close left blowing nozzle and right blowing nozzle, being blown by front blowing nozzle is blown into runner by nut.
When blowing nozzle is blown in distributing buffer pond, air pressure inside is higher than external pressure, owing to being communicated with outside by the pressure release passage on the bleed passage on block and front blowing nozzle side in distributing buffer pond, now inner high pressure air will flow to bleed passage by runner, flow to outside again, simultaneously inner high pressure air also can be outflowed by pressure release passage.Can the nut near flow channel entry point be brought into runner by the air-flow of disappointing runner, directly enter flow field end, but cannot bleed passage be passed through.Owing to having small―gap suture between nut and distribution channel side wall, the follow-up nut that also has enters runner, until be booked nut in runner.After being booked nut in runner, the high pressure air in nut pond is discharged mainly through pressure release passage, prevents that internal pressure is too high blows quick-fried transparent cover plate, and pressure release passage can not be filled by nut, can not block, and plays safety effect.
Cylindrical articles feedway in above embodiment can as the accessory equipment of injection machine, and supply nut is to manipulator automatically, realizes preset nut automation in the mould in plastic rubber shaping process.Certainly, except nut, also can be used for the automatic supply of other cylindrical finding.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; some equivalent to substitute or obvious modification can also be made, and performance or purposes identical, all should be considered as belonging to protection domain of the present utility model.
