Follow paper separating device
Technical field
The utility model is related to be carried out on a kind of paper (box) case production machinery more particularly to the machine to having pasted paper (box) case
The folded improvement for dividing the paper separating device structure before pile of code.
Background technology
Uncoated paper after color printing, pasting, cross cutting carries out autosizing by paste paper folding (box) punch-out equipment, hooks bottom, folding, bonding
Etc. after case base is made in processes, often needed for ease of transporting and going out storage points using being set to beating for road after paste paper folding (box) punch-out equipment
Packet strapper carries out fixed number packing to case base, in the process to realize that the case base number being packaged per pile is regulation number, then
The paper separating device being set on the machine is essential.Paper separating device used is by two sections of different conveyings of speed on existing machine
Band composition, wherein weathering zone are responsible for the case base being stacked in fish scale-shaped transmitted by paste paper folding (box) punch-out equipment synchronizing conveying,
The case base spacing that weathering zone is sent then is pulled open and on the code paper platform that is delivered under stationary state by hyper tape, and
Constantly tired height on code paper platform is set to the sensor of high speed end of tape to being counted by the case base under it in the process
Number, when count value reaches setting value, sensor for countering is to control system input signal, and triggers the power of driving code paper platform
Source acts, and paper station is fallen to realize to transport the paper stack for setting number, and the subsequent case base to be come by hyper tape conveying continues to fall
Tired code is carried out on code paper platform, repeatedly.Case base is determined though this paper separating device being made of high weathering zone can be realized
Number separation purpose, but the accuracy of the stability and counting for guarantee separation, adjacent sheets must keep certain on hyper tape
On the one hand spacing will certainly make high speed delivery section length long in this way, still it is delivery section increment meeting when paper height is longer
It becomes apparent, also just brings the increase of occupation area of equipment, cause the waste of production site, on the other hand produced to improve
Yield, high speed delivery section will certainly also be operated with conveying speed quickly, and what the conveyer belt under running at high speed conveyed paper
Stability is also necessarily deteriorated, and so as to form the contradiction between speed and stability, it is low that there are production yields, and production efficiency is not high
Defect.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of not only production efficiency height, but also floor space is small,
