Abstract
A paper sheet coating apparatus with gas stream drying comprising a coating device (14); a sheet conveyer (22) having 5 permeable belts (20, 23) and its lower side being connected to a sheet exit of the coating device; means (19) for supplying and directing gas streams; sheet reversing means (24) connected to the end of said sheet conveyer; and a sheet collector (26) which collects (10) dried sheets and covers the apparatus.
Description
PAPER SHEET COATING APPARATUS WITH GAS STREAMS DRYING
This invention relates to a paper sheet coating apparatus with gas streams drying and auxiliary transporting system. The term "sheet" used hereafter indicates paper sheet, particularly photographic paper sheet. The coating machine commonly used is described with reference to the accompanying drawing Fig.l. Sheets pass through coating means which comprises a driving roller 2, a lacquering roller 1 and a pushing roller 3, then they are carried by a conveyer 9 forward to a sheets collector 11. A electric heat-drying means 10 is set above the conveyer 9. A scraper 4 presses the pushing roller 3 to clean it. The lacquer squeezed passes through a lacquer collector 5 and flows toward lacquer container 6. A pump 7 and lacquer pipe 8 lead lacquer up to lacquering roller 1. The overcharged lacquer passes through upper lacquer collector 12 and lacquer leading pipe 13, then flows into lacquer collector 5. This apparatus needs large space, because there should be enough area in said heat-drying means to secure thermal uniformity during heat-drying processing, and at the end of the conveyer 9, a sheets collector 11 occupied another range lengthwise. But under the conveyer 9, a considerable area is not used.
The object of this invention is to provide a sheet coating apparatus with gas streams drying and auxiliary transporting system. It is constructed compactly and effectively.
The object has been attained by the paper sheet coating apparatus with gas streams drying and auxiliary transporting system according to this invention, which comprises: coating means whose sheet exit is in accord with lower side of sheets conveyer; said sheets conveyer having conveyer belts which are permeable to gas streams; means for supplying and directing gas streams which blow crosswise onto coated side of sheets or pass through said conveyer belts, spaced under said sheets conveyer; sheets reversing means embracing the end of said sheets conveyer; sheets collector mounted above said sheets conveyer, carrying both effects of covering machine and collecting sheets dried.
Sheets pass through coating means and are lacquered only on one side. The wet coated sheets are pushed toward said sheets conveyer in which the coated side of the sheets faces said means for supplying and
directing gas streams and their bare side is pressed against said conveyer belts by the gas streams. The gas streams blow crosswise onto the wet coated sheets and dry them during the travel. Said sheets reversing means is capable of guiding sheets between sheets reversing means and sheets conveyer to reverse back toward the sheet entering direction, and pushing sheets out off from said sheets conveyer. The coated and dried sheets depart from said conveyer and fall on the sheets collector carrying both effects of covering machine and collecting sheets dried.
The advantage of this invention is of creative compacting the length of conveyer, saving the space for the sheets collector and sufficient use of the space in and out the apparatus.
The invention will be better understood by an embodiment from the following description which is made with reference to the accompanying drawings. Fig. 2 and Fig. 3 are the elevation view and plan view of the paper sheets coating apparatus with air streams drying and auxiliary transporting system. This apparatus has: apparatus stand 27; driving motor 25; coating means which comprises lacquer tray 18, lacquer roller 16, coating roller 14, pressure roller 15, supporting roller 17, squeegee 28 pressed on pressure roller 15; said
lacquer roller 16, coating roller 14 and pressure roller 15 contact each other parallelly; sheets conveyer which comprises driving wheel 22, idler wheel 21, rubber conveyer belts 20 spaced apart parallelly and therefor being permeable to air streams; The sheet exit of said coating means is in accord with lower side of said sheets conveyer; fans 19, as means for supplying and directing air streams, spaced under said sheets conveyer; sheets reversing means embracing the end of said sheets conveyer, and comprising reversing wheel system 24 with rubber belt 23; sheets collector 26 mounted above said sheets conveyer, carrying both effects of covering machine and collecting sheets 29 dried. Said lacquer roller 16 im erged partially in lacquer tray 18 carries lacquer to coating roller 14. Sheets 29 are pushed forward between coating roller 14 and pressure roller 15 for lacquering. A squeegee 28 pressed on pressure roller 15 scrapes the lacquer on the pressure roller 15. After lacquering processing, the wet coated paper sheets are forced to the paper sheets conveyer and their coated side faces the air streams. The air streams generated by fans 19 blow crosswise onto sheets and press said sheets against conveyer belts 20. Therefor said sheets are dried by air streams during the travel. The dried paper sheet between said rubber belt 23 of said sheets reversing means and rubber conveyer belts 20 of
said sheets conveyer is reversed back toward the sheet entering direction and pushed out off on the sheets collector 26 carrying both effects of covering machine and collecting sheets.
