Description

Device for the packing sa transport of flat articles of flexible ΗΑ2Ϊ3 JACOB 29915 As there are numerous flexible articles for bank which when no properly packed are easily damaged and become virtually with the packaging means at present available which used in normal pneumatic posting or even in personal conveyance by damage cannot be for example bank documents are at present as for the last 30 still rolled up in conventional pneumatic post cassettes when being sent by pneumatic These rolled up documents clearly press tightly against the wall of the container on account of inherent and are for this reason difficult to remove without being The same is obviously true a larger extent in the case of for example taken for example in the case of operations i personally by a messenger after they have been to the place where they are to be and have to be collected process in which the films are put in relatively heavy is particularly unsatisfactory where the result of an must available as soon as In the case of operations i can example be of decisive importance whether it is possible to develop an immediately and bring it to the operating Attempts nave been made to accelerate the conveyance of by means of pneumatic it was soon shown that films are very easily damaged and i particular become scratched when using the conventional pneumatic post The films have to be on account of their It can easily be seen that these can be removed from the box only with and in particular that damage by scratching cannot be The effects of such on the result of an investigation may be exceptionally as can easily be Shis is the chief reason why up to present time pneumatic post has not been successfully used in conveying undeveloped normal posting is even less adapted to such Quite apart from the insufficient stiffness of conventional envelopes there is in this case the added risk of tearing or cutting on Accordin to the presen which seeks to obviate the said a device for the packing and safe transport of flat articles o flexible material is characterised b a practically cylindrical cassette which has a longitudinal slit parallel to its longitudinal the length the sli corresponding t least the width of the article to be a cylindrical spool rotatably mounted coaxially in this cassette and by of a mechanism coupled at least two protective each secured at one end to the said the dimensions of the sheets corresponding at least to those of the article to be and a fla working surface corresponding at least to the measurements of the article to be the arrangement being such that the article to be conveyed an e e trans b ben laed between the two protective sheets when these latter project from the slit of the cassette and lie on the working and the two protective sheets which enclose the article wound up by of the said mechanism and thus simultaneously drawn into the the surfaces of the article thereby being In a preferred embodiment of the the spool can be coupled with a drive an electric by a frictional In this case the coupling is preferably effected via a cone attached to the shaft of the drive against which a face of the spool or a recess provided therein can be One edge of the working surface advantageously has a depression into which from the actuating member of a switch in circuit with a drive the actuating member being of a type that switch can be actuated by simply placing the cassette in the said In this case the spool preferably projects out of the cassette on one side and has a friction wheel at the end which comes into frictional when the cassette is placed in the with a mating wheel disposed below said trough and which is coupled with the shaft of the drive in an elastic restoring means can be arranged within the spool which is secured at one end to the body of the spool and at the other end to the body of the and which is tensioned when the protective sheets are withdrawn from the cassette and subsequently automatically draws the protective sheets back into the One embodiment of the device in accordance with the invention will now be by way of with reference to the accompanying in Figure 1 is a simplified perspective view of a device with an electric motor drive for packing undeveloped Figure 2 is a detail of the device shown Figure Figures 5 to 6 show different embodiments of the cassette or the spool arranged and Figure 7 shows a commercially used pneumatic conveyor with an film cassette inserted Figure 1 shows a working generally designated which can be made for example out of metal or and which has a flat working surface The working surface 2 is substantially rectangular and its dimensions are preferably chosen to be somewhat large than those of the film to be A depression abuts one edge of the working surface on the side facing the the depression being bounded on the front side by a curved wall A cassette 4 is located in this and is further described with the aid of Figures 2 and The cassette has a cylindrical casing 5 which provided with a longitudinal slit 6 1 and extending over the length of the cassette A cylindrical spool 7 is rotatably mounted on support rings 8 within the oassette excessive and undeslred axial displacement of the spool being prevented by As Figure particular the spool 7 has a recess in its left into which a 12 which is coupled with a shaft 10 of an electric motor It can be easily seen that so long as the spool 7 urged to the left in the direction of the arrow it engages frictionally with the 12 and rotated Two support sheets 14 1 and of transparent flexible material are secured a one end to the spool while the two free ends of the sheets project from 6 the cassette one grasps the support sheets 14 two fingers by the tongue 15 shown in Figure 1 and them out of the the two sheets above one another on the flat working surface If on the other hand the spool 7 brought into via the cone with the electric motor in the of the arrow the support sheets 14 are wound up and thus drawn into the interior of the cassette 4 device which serves for packing of undeveloped film is advantageously employed as the support sheets 14 are first of all withdrawn by hand position shown in Figure 1 so to the right that they fully lie on the flat working surface She undeveloped 17 is then laid between the two whereupo the spool 7 is coupled the electric motor by displacement the sense of the arrow In this way the two support sheets 14 and the 17 are wound into interior the the film surfaces thereby being to the fullest possible and the film is Far this purpose the cassette can placed in a commercially available pneumatic post conveyor 18 in Figure It is to be understood that the insertion of the film in the oassette 4 must be carried out in a withdrawal of the film from the cassette 4 is extremely The cassette again placed in the depression of a similar working table whereupon the two support sheets 14 and the film can be directly withdrawn from In the variant shown in Figure an actuating member a 18 of a switch 19 arranged in circuit with the drive for example the electric motor projects from below into the depression serving as the container for the cassette the cassette 4 in the 18 thus urged downwardly by the wall of the cassette and the switch is and the drive means thereby in this arrangement the spool 7 projects out from the cassette 4 on one side and has a friction whee 20 located on projecting friction wheel into contact with a mating wheel 21 arranged below the depression when the oassette 4 is placed in the mating wheel being rigidly attached to the shaft of a drive The frlctional contact between the wheels 20 and 21 can be improved by pressure applied to one end of the In order to ensure frlctional contac between the friction wheels 20 and 21 all it would clearly also possible make the lower part the depression 22 in Figure out of an elastic Ths material could thus yield the pressure of the cassette so that the frcitional pressure between the two wheela 20 and 21 could also arbitrarily A simplified variant of the cassette 4 is shown in Figure The spoo which is formed as a hollow at its end shown in the a spigot projecting inwardly from an end of the while the end of the spool 7 is supported by means of a ring bearing A coil sprin is arranged i the interior of the spool the end of spring being secured to the spigot 23 and the end of the spring being rigidly via an insert to the cylindrical wall of the spool If the 7 rotated relative to the cassette by pulling out the support sheets 14 secured the spring 25 is automatically soon as the support sheets 14 are they are onoe again wound up on the spool on account of the restoring exerted by the spring and are thus pulled back into the interior of the cassette In this embodiment is convenient to provide the tongue 15 on the loading edge of the support sheets 14 wth an aperture so that the tongue can engage with a hook 27 located at the opposite end of the working I would also be clearly to provide another securing for example an in plaoe of the hook In all the variants the tongue 15 of the upper support sheet 14 conveniently has a elevation which strikes the upper edge of the slit 6 wien drawing in the support the result that a the tongue always from the slit 6 and can he device described is clearly suitable not packing and pneumatic conveyance of undeveloped but also uite generally for packing flat articles and the and safe transport of larger articles of It thus possible with this device to pack any flexible particularly easily creasable documents such as sensitive transparent original oil paintings on paper or canvas or in the safest possible and to recover the package undamaged at its insufficientOCRQuality
