Abstract
Protection device against flinders bursting from a reel core (6) of reel changer. It takes the form of a capturing grate on the moving reel platform (2) fastened to the frame (11) as well as sheet protection (14) on the reel stand (10).
Description
Technical field
The present invention relates to a kind of reel changer that is used for a kind of printer, this reel changer has been equipped with remaining reel lining fragment protective device.
Background technology
By the known reel changer of prior art, and for example in EP 0 436 825 or EP 1 223134, have been described in detail.This reel changer is for guaranteeing that handling paper roll continuously has a supporting arm, and this supporting arm can put a paper roll in its end respectively.If the paper roll on supporting arm first side of reel pedestal almost will exhaust, reel pedestal is with regard to the paper roll of rotating support on the supporting arm opposite side, thereby after through a definite traverse time, just this new paper roll can be used for production process, stick on the paper web face of the paper roll that soon exhausts at the paper web face of new paper roll in this traverse time.
For the paper roll that has run out of now, according to prior art on the disclosed mobile station, new paper roll is shifted to reel bracket and is moved on on the reel pedestal thus equally.Mobile station is shifted to reel bracket in a zone, below this zone is called the loading side.
The personnel that stop in the zone of this loading side are endangered because of two reasons.One can damage loading the mobile station that side moves around, its two lining of paper roll that can occur exhausting or that almost exhaust this situation of breaking again.Below the diameter of a paper roll that exhaust or that almost exhaust is called cut off diameter.With a paper roll and the high speed revolution that thus should the remnants lining can reach the time, the fragmentation of lining is equivalent to once explode, and many big and small lining fragments are thrown out of by air in this blast.
By prior art, rolling door is set prevents that personnel are subjected to the harm that the reel lining breaks and causes, such rolling door can be used for protection under the loading layback.These rolling doors or must electronic control, thus they only under paper roll reaches the situation of cut off diameter, just handle, or these rolling doors must forever close, thereby must must they be removed when the loading side is carried out operation the professional at every turn.
Summary of the invention
According to the prior art of quoting; task of the present invention is a kind of reel changer that is used for printer of design, thus especially in loading the side scope as far as possible reliably and inexpensively at first critical just concerning personnel dangerous printing process in the time personnel are protected.
This task is resolved by reel changer of the present invention.
According to the present invention, a kind of reel changer with a reel bracket is disclosed.This reel bracket is admitting one to treat the printed volume tube on a supporting arm again, for example a paper roll.In addition, this reel changer has a mobile station, and this mobile station will have pending reel to carry from loading the side direction reel bracket.By the present invention, protective device of reel changer equipment is used to capture all fragments of the reel lining that breaks.
By the present invention, a protective device correspondingly directly is set on reel changer, it is suitable for capturing efficiently all fragments of the remaining reel lining that breaks, thus these personnel in the reel changer zone can not come to harm.This protective device can for example be configured to the sheet material form on the reel bracket and/or also can be configured to the form of the collecter ring on the mobile station.By the present invention, material and shape that institute's protective device uses can change arbitrarily, as long as only so construct this protective device, thereby make the fragment institute of the reel lining that its blockade breaks might flight path.
By a kind of first improvement project of the present invention, this protective device comprises that directly being fixed on first on the reel bracket captures mechanism.This first capture mechanism can for example be made by sheet material, and these sheet materials are arranged between the remaining part of reel bracket, thereby seal all possible flight path of the fragment of the reel lining that breaks.Also can use corresponding solid or netted Plastic Parts to replace sheet material.Directly be fixed on first on the reel bracket thus and capture all flight paths that mechanism has blocked the fragment of the remaining part that directly passes reel bracket.But also can so construct first in addition and capture mechanism, thereby block the flight path of fragment along reel bracket.Particularly preferably a kind of first captures mechanism, its can block fragment all fly away from the possible flight path of reel bracket.
For covering all flight paths of fragment as far as possible, preferably the first smooth capture mechanism is positioned on all directions, thereby be provided with side member and lateral member by a kind of improvement project of the present invention, side member is substantially perpendicular to the rotation axis of supporting arm and arranges, lateral member then is provided with the rotation axis of supporting arm with its surface basically with paralleling.This structure has realized that first captures mechanism and be fixed on the parts by the disclosed reel bracket of prior art fairly simplely.First lateral member that captures mechanism especially can be fixed on one by on the disclosed side member of prior art and the crossbeam and/or on bolster and the crossbeam.
By another kind of improvement project of the present invention, this protective device has one second and captures mechanism.This second capture mechanism is fixed on above the mobile station of reel changer.Be fixed on the mobile station by capturing mechanism, just use a part of protective device in the time of can reaching critical value at the diameter of remaining reel, that is to say, just use the part of protective device when having only remaining lining that risk of rupture is arranged second.Only reach under the situation of cut off diameter at the reel that uses in advance, just need a new reel, this moment, mobile station was just shifted to reel bracket.Can in a process status that is necessary to protect, protect the reel bracket region in front thus.Therefore, reel bracket fwd loading area can free in and out in remaining time.In addition, preferred this form of implementation is can keep less size because directly be fixed on the capture of first on reel bracket mechanism, and can be installed on the reel bracket simply thus.
Design second captures mechanism, thus the possible flight path of the institute that makes it especially block the reel lining fragment that breaks, as long as these flight paths are derived from reel bracket and especially fly to the direction of loading side.According to the space situation of installation site, reel bracket place, can correspondingly capture mechanism and adjust second.That is to say,, then there is no need to be provided with second and capture mechanism in the sidewall front if sidewall has been arranged on the reel bracket next door.But also will protect if necessary in the zone on reel bracket next door, that also can be provided with second in the side towards mobile station and capture mechanism on the loading direction.
Second captures mechanism for example can be made of a pipe support structure, and this pipe support structure has one and is clamped in the collecter ring between the pipe support or captures grid.At this, these capture grid can be the steel grid.But also can consider more resilient or more crash-resistant material, this must select according to the type of fragment.Why preferred a kind of collecter ring of preferred elastomeric or capture grid are, is because it can absorb the kinetic energy of the fragment that disorderly flies everywhere, if abandon this collecter ring or capture grid, then can abandon the pipe support structure equally.Then, second captures mechanism can for example be made by a kind of sheet material, but also can be made by transparent plastics, just contacts with the sight of reel bracket like this and can not interrupt.In addition, a remaining lining container can be set on mobile station, so construct this container, thereby make it satisfy the function of the second capture mechanism.
Second structure that captures mechanism depends on that first captures the structure and the layout of mechanism, that is to say, covers if the specific flight path of fragment is not captured mechanism by first, and these flight paths are just covered by the second capture mechanism so.Therefore such result can occur, i.e. all sides of reel bracket be covered but a zone that also comprises the reel bracket top all must capture mechanism by second.In order to cover a zone of reel bracket top, preferably collecter ring between the pipe support structure or capture grid are placed in a pipe support structure that is provided with the corresponding collecter ring of the side that is used for the reel bracket next door.Should above second capture mechanism then can be at a slant or on even keel extend towards the reel bracket direction, thereby make the fragment of the remaining reel lining that breaks can't upwards fly away from a carriage.
