Abstract
Individual removal of flat flexible articles from the bottom of a pile is effected by downwardly deflecting the front edge of the article to form a deflection (7) while drawing the side edges of the article (3) inwards. The deflection (7) is formed initially by vertically movable suction discs (10) and can be maintained after termination of the suction in the discs (10) and during at least a part of the removal of the article (3) by other gripping means, such as suction heads (12, 18), which grip the article (3) in its front edge zones adjoining the zone of deflection (7). The lowermost article is laterally removed by the reciprocating table (4) and the associated suction heads (12, 18). The remaining articles (2) are kept back in the pile (1) by a stop finger (5) having a lowermost end (8) below the level of the supported pile bottom. The article can be deflected by a stationary suction head positioned between a pair of conveyors removing the lowermost article (Figures 8 and 9) and the leading edge of the article may be bowed partially upwards in its central region (Figures 9-11) by a shaped suction panel. The lower front edge of the stop fingers is barbed and pointed (Figure 13) to assist retention of the remaining articles in the pile. <IMAGE>
Description
SPECIFICATION
Method and device for individual removal of flat flexible articles from a pile bottom
The present invention concerns a method and a device for individual removal of flat flexible articles in a removal direction from the bottom of a pile of articles and in accordance with the opening clauses of claim 1 and 4, respectively.
From Swedish Patent No. 96722 is known a device of the mentioned art in which, however, the articles are only gripped in their deformed deflected zones during the entire removal, whereby the articles are only gripped with a weak suction force, being limited by the areas of the cavities of suction. Furthermore, at the stop means of the articles the vertical distance of the slot should be slightly larger than the thickness of the articles. Furthermore the lowest point of the stop means seems to be tangent to the bottom of the pile of articles, i.e. the upper surface of the support. Consequently there is a risk that more than one thin article of a thickness of e.g. 0.1 mm could be drawn through the slot if the articles are porous, so that thick articles such as 12-pages newspapers will not at all be sucked or drawn with below the stop means.
The method of the invention is characterized by measures stated in the characterizing clause of claim
1. By means of these measures the lowermost article is caused to make a considerable, local deflection from the bottom surface of the next article and when this deflection is large enough for the lowermost article only to pass the stop means unobstructedly the stop means detains the remaining articles being in an substantially plane condition because the lower end of the stop means is situated in a lower level than the supporting surface of the pile. This has surprisingly caused a rather high certainty for only individual removal of as well rather thin articles such as paper sheets as rather thick articles such as news papers, and so that the rate of removal can be rather high, e.g. 5 articles or more per second.
In a preferred embodiment of the method the lowermost article is given a local relative upward deflection extending above the plane edge zones of the article on one side of the local downward deflection, the downward deflection need not to extend completely from the front edge to the rear edge of the article whereby removal energy is saved, since suction force is necessary only in a zone near the front edge of the lowermost article. Furthermore the front of the pile bottom is supported only on the support areas of the upward deflections so that the edge zone of the article cannot be gripped until the mechanical increase of the downward deflection of the article has taken place.
In another preferred embodiment of the method, the entire downward deflection is made by means of a suction disk connected to a vacuum source and which is guided and moved in a substantially vertical path, the suction disk during its downward movement supplies suction force to the lowermost article, and suction means on both sides of the downward deflection zone of the article supplies suction force to the article to maintain this on the suction means during the removal in the outlet direction after the suction disk has terminated its suction.
The device according to the invention is characterized by the measures of the characterizing clause of claim 4. Thereby a device is provided in which the advantages of the method can be employed. As removal means may be used a reciprocately displaceable support table. The excessive downward deflection of the lowermost articles causes only this article to be drawn below the lower edge of the stop means and, the article being free of engagement with the stop means, can be drawn from the pile by means of and together with the displaceable removal means.
The invention will hereinafter be explained in more detail with reference to some embodiments and the drawings, in which:

Figure 12 shows the lower end of the stop finger with rectifying and brake means seen from the interior of the pile magazine, and
Figure 13 shows a section aong the line XIX-XIX of
Figure 12.
Figure 1 shows a pile of articles 2 of which the lowermost article 3 is to be removed from the pile 1, which pile is supported by a support 4, here being in the form of a reciprocately displaceable support table. In order to remove the lowermost article 3 said article must pass a stop finger 5 adapted to stop at least the articles 2 above the lowermost article 3.
Figure 1 shows the pile on its support 4 behind the stop finger 5 the outlet or removal direction 6 shown as an arrow.
Figure 2 shows a part of the principle of the invention whereby a suction disk 10 locally gives a downward deflection to the lowermost article 3 relatively to the overlying articles 2 so that the lowermost article 3 at its front edge in the removal direction 6 can pass the stop finger 5 as shown in
Figure 3 where the downward deflection 7 allows the article 3 to pass below the lower end 8 of the stop finger 5.In this way the lowermost article 3 in the pile 1 is given a local relative downward deflection 7 before its removal by means of the partial vacuum and downward movement of the suction disk 10, which deflection 7 extends from between the ends of the front edge 9 of the article 3 and which in the embodiment shown extends almost to the rear edge of the article 3 and during removal of the article 3 from the pile 1 this downward deflection 7 is retained by the means mentioned in connection with
Figures 4 and 5 as the articles 2 above the lowermost article 3 are kept back by the stop finger 5 such as a rod being placed above the zone of a local downward deflection. This downward deflection 7 gives a waveform to the lowermost article so that the article has a cavity in its upper surface and a raised part in its lower surface.This firmly gripped waveform gives a larger stiffness to the article 3 in the removal direction 6 than would be the case if the article 3 had been removed in plane condition.
In a preferred embodiment of the method the lowermost article 3 is given a local relative upward deflection on one side of the local downward deflection 7 as mentioned in connection with Figures 9-11 whereby partly said stiffness is further increased and partly that the lower end 8 of the stop finger 5 need not extend all the way down to the upper surface of the support 4. Furthermore, when the upward deflections are adapted so that the central zone of the downward deflection extends parallel to the removal direction along the entire length of the downward deflection e.g. as will be the case in a device with the support table 4 shown in
Figures 10 and 11 energy can be saved, as suction force is necessary only in a downward deflection zone near the front edge of the lowermost article.
In the device shown in Figure 1 the downward deflection as mentioned is carried out by means of the suction disk 10 being adapted to be displaced in a path substantially perpendicular to the removal direction 6 and the suction disk 10 is adapted only to supply suction force to the lower-most article 3 during the downward movement of the disk 10. As soon as a downward deflection has been given to the lowermost article 3 suction members 12 in the form of suction holes as shown in Figure 5 grip by suction the article 3 in its downward deflected position on both sides of the downward deflection zone by suction force in order to take along the article 3 in the direction 6 of removal, when the suction disk 10 after a predetermined downward movement terminates its suction force supply.Figure 2 shows the article 3 in its downward deflected position and Figure 3 shows the article 3 partly removed from the pile 1 in a position in which removal rollers 14 take over the removal function. In
Figure 1 the lower edge 8 of the stop finger 5 is placed at the same level or lower than the top side of the support table 4 and another stop finger at the rear edge of the article has its lower edge positioned lower than the level of the support table 4 in a recess 36 in the support table 4.
Figure 4 shows a section along the line VIlI-VIlI of
Figure 1 Two side guides 16 at the side edges of the articles 2 keep the pile 1 in place. Below the top side level of the support table 4 suction members 12, suction disks 10, suction head 18, and a lower removal roller 14 are provided. As soon as the lowermost article 3 has been given its downward deflection 7 as shown in Figure 5 the lowermost article 3 is gripped by the suction members 12 as well as by the suction head 18 after the suction disks 10 have terminated their suction engagement with the article 3. In this suction gripped form held by the head 18 and members 12 the article 3 is drawn from the pile 1 and passes the lowermost ends 8 of the stop fingers 5. The suction heads 18 of Figures 4 and 5 have a plain surface. Figure 6 shows a function diagram for the device of Figures 1-5.In the four systems coordinates is in the first system shown the travel of the suction disks 10, in the second system is shown the partial vacuum supplied by the suction disks, in the third system is shown the partial vacuum supplied by the suction head 10 and the suction members 12 with suction hole, and in the fourth system is shown the travel of the support table 4, all as a function of the time. By vertical broken lines is shown how the different functions are mutually synchronized, and such synchronization takes place either mechanically, electrically, hyd raulically or pneumatically. The word cycle of the device may start by lifting the suction disks 10 and as seen in Figure 6 the suction disks 10 are supplied with a partial vacuum in their uppermost position in which they suck in the lowermost article 3.Then the suction disks 10 are lowered and having almost reached their lowermost position, Figure 5,a partial vacuum is supplied to the suction head 18 and the suction members 12 with suction holes. Then the support table 4with suction heads 18 and suction members 12 is moved forwards while the suction disks 10 remain stationary in their lowermost position. The suction of the suction disks 10 was terminated after the suction of the suction head 18 and of the suction members 12 was supplied. When the table 4 has been moved forwards to its forward end position the partial vacuum in the suction head 18 and in the suction members 12 becomes terminated simultaneously with the supporting rollers 14 taking over the removal movement of the article 3.
Then the table 4 will be returned to its start position and a new work cyclus for the next lowermost article 3 can be initiated. In Figure 6 T stands for time, e.g. in seconds, S stands for stroke length, e.g. in mm, and
U stands for partial vacuum, e.g. in % vacuum.
Figure 7 shows a device according to the invention in which the support table 4 is replaced by a conveyor band 26 and a stationary pile and conveyor band support. The conveyor band extending over the stationary suction head 28 having a concave suction surface is porous of air permeable for transferring of the partial vacuum from the suction head to the lowermost article 3. Figure 8 shows the device of Figure 7 in section along the line XIV-XIV of
Figure 7. Simultaneously with the downward deflection of the lowermost article 3 in the zone of the suction head 28 a displacement of the side edges of the article 3 from the side guides 16 takes place as shown in Figure 8. All bands 26 are driven by a drive roll 30 and are at the outlet side of the device carried by support rollers 32 mounted freely rotatable on a common shaft.
Figure 9 shows a plan view of an embodiment of the table 4 which is supplied with two throughgoing recesses 34 positioned between the suction head 20 and the suction members 12 formed as suction holes. Furthermore two longitudinal grooves 36 are provided in the top side of the table 4, in which grooves the stop fingers for the rear edges of the articles extend downwardly during the reciprocate movement of the table.
Figure 10 shows a particularly advantageous embodiment of the suction zone in section along the line XVI-XVl of Figure 9. The concave zone is cylindric, the generatrices of which extend parallel to the top surface of the table and also to the outlet direction 6. The upper part of the suction head 20 is formed by a separate part 38 which, when fixed to the table 4, together with the table 4 forms a suction chamber 40 which is connected to a vacuum source and via suction holes 42 is connected to the top surface of the suction head for suction of the lower-most article 3. On both sides of the concave zone the part 38 is provided with elevations or raised ramps 44, the top surface of which extends with an angle A to the top surface of the table 4.The angle A may be between 1" and 8", preferably 2". Thereby the lowermost part of the concave zone extends in the plane of the table 4 which furthermore implies that the lowermost end 8 of the central stop finger 5 can be positioned above the plane of the table 4 in a distance above this being larger than the thickness of the lowermost article 3 without any risk that the articles 2 positioned above the article 3 can pass the central stop fingerS. The lower-most article 3 which is removed by a support table 4 as shown in Figures 9-11 is thereby provided with three cavities and two elevations in its upper side extending along the removal direction and this gives the article a large stiffness during its removal.The two outermost stop fingers 5 have their lowermost ends 8 below the top surface of the table 4 due to the very large deflection of the lowermost article 3 by means of the suction and the mechanical movement of the suction disks 10 and the firm grip by the suction members 12 of the lowermost article 3 in its deformed condition during removal.
Figures 12 and 13 show a particular embodiment of the lowermost end 8 of e.g. the central stop finger 5, said finger being provided with a rectifying means 46 which is provided with a barb 48 and being adapted to abut that side of the pile 1 turned against the stop finger 5 and to prevent upward displacement of the front edges 9 of the articles 2. This is shown best in Figure 13 where the barb 48 points downwards towards article front edges (not shown).
In the center of the lowermost end 8 of the stop finger 5 a brake means 50 is provided comprising a pointed pin 52 at an adjusting screw 54. Between the head of the screw 54 and the rectifying means 46 a compression spring 56 is positioned. The point of the pin 52 is to abut the front edges of the articles 2 during their downward passage by the successive removal of the lowermost articles 3. By means of the adjusting screw 54 the resistance of the brake means 50 against the downward displacement of the front edges of the articles 2 can be adjusted to a valve which prevents a downward displacement of the front edge of the article positioned above the lowermost article 3 before this has been removed.
During the forward movement of the table the front edges 9 of the articles 2 will be inclined to slide upwards along the stop finger 5 but this is prevented by the barb 48.
The measures shown in connection with a reciprocatable table 4 can of course be used in connection with a reciprocatable conveyor band or with a continuously or intermittently driven conveyor band.
A device for carrying out the method of the invention is as mentioned suitable for securing individual removal of thin articles in particular.
However, the device can also be used for individual removal of thick, stiff articles in case of an embodiment as shown e.g. in Figures 4 and 5. In this case it is sufficient to disengage the function of the suction disks 10 and place the stop fingers 5 in a distance above the top side of the table 4 corresponding to the thickness of the articles with the addition of at most 10%.
In a practical embodiment of the device the partial vacuum employed is 85% corresponding to an absolute pressure of about 0.15 bar. By drive motor of 1500 watt for removal of the articles and a vacuum pump of 370 watt was obtained 20.000 articles removed per hour.
