Abstract
A method of advancing packaging blanks disposed standing upright in a magazine, one after the other, in a file or queue resting against the bottom of the magazine and disposed to be driven forwards through the magazine towards a stop at an outlet end for individual discharge comprises the file or queue of blanks being divided into two pressure zones, a first and forward pressure zone extending from the zone limit between the pressure zones up to the stop and displaying a first mutual pressure between neighboring blanks, as well as a rear second pressure zone displaying a second mutual pressure between neighboring blanks. The first mutual pressure is higher than the second mutual pressure. Another aspect of the disclosure pertains to an apparatus for carrying out advancement of the packaging blanks.
Description
- The present invention relates to a method and an apparatus in the advancement of packaging blanks disposed standing on end in a magazine, one after the other, and resting with one edge side against the bottom of the magazine.
- Apparatuses for automatically feeding flat-folded packaging blanks, for example cartons—with or without laminate—to a filling machine for raising and filling are previously known in the art. One such apparatus displays a magazine for packaging blanks and a discharge device for individual discharge of these blanks one by one out of the magazine.
- The magazine usually displays a channel in which the blanks are disposed in queue or file for feeding through the magazine towards the discharge device. The channel displays a bottom which supports the blanks, side walls which laterally define the channel and guide the blanks, a front stop against which the first blank in the magazine is urged in order, in this position, to be grippable by the discharge device for discharge out of the magazine, as well as a carrier which, by applying a force from the rear against the last blank in the magazine thereby urges the first blank in the magazine against the stop,
- In magazines of the above-mentioned type it is desirable to realise an even and uniform advancement of the blanks on their displacement through the magazine. This has hitherto been realised int. al. in that various measures have been implemented to minimise the friction which occurs between the bottom of the magazine and that part of the blanks resting against the bottom.
- Another measure which has been proposed in the art is to provide control devices which regulate the force which, via carriers, abuts against the last blank in the magazine which, by a transfer of force via all of the other blanks in the magazine, finally urges the first blank in the magazine against the stop. This force is proposed to be greater when the magazine is full and smaller when the magazine contains a smaller quantity of blanks.
- A further phenomenon to take into consideration when blanks are to be advanced through a magazine is the so-called spring back effect. This occurs when flat-folded, folded over/flattened blanks show a tendency to spring back to a state of equilibrium which, for example, may contribute to an advancement force which defies ready control.
- The object of the present invention is to realise a reliable advancement of packaging blanks through a magazine towards a stop at an outlet end of the magazine.
- This object is attained by means of a method and an apparatus in the advancement of packaging blanks disposed standing upright in a magazine, one after the other, in a sequence with their respective lower edge regions resting against the bottom of the magazine and disposed to be driven forwards through the magazine towards a stop at an outlet end for the individual discharge of blanks, and which displays the characterising features as defined in the appended independent Claims.
- In one embodiment, the method may include the step that the file or queue of blanks is divided into two pressure zones, a first and forward pressure zone extending from a zone limit between the pressure zones up towards the stop and displaying a first mutual pressure between neighbouring blanks, as well as a rear, second pressure zone displaying a second mutual pressure between neighbouring blanks, and that said first mutual pressure is higher than said second mutual pressure.
- In other embodiments, devices displaying an elevated peripheral speed may be applied against the file of blanks from opposing directions locally at the zone limit for the formation of the relatively higher pressure in said forward pressure zone.
- In yet further embodiments, the peripheral speed of the device in contact with a blank may be directed to drive the blank in a direction towards the outlet end of the magazine and exceed the advancement speed of blanks required at the pertinent discharge speed out of the magazine.
- An apparatus according to the present invention may, in conjunction with the discharge end on either side of the file of blanks, display friction means disposed in contact with a number of the blanks disposed in the magazine, and the friction means in each respective contact may display a peripheral speed in a direction towards the outlet end which exceeds the advancement speed for the blanks required at the pertinent discharge speed. There will hereby be formed a zone between the friction means and the stop at a relatively elevated pressure compared with the general pressure prevailing in the remainder of the file of blanks, in which event the zone may be described as a dynamic pressure and adaptation zone for correct arrangement of the formermost blank against said stop.
- Moreover, in yet a further embodiment, the friction means may display flexible projections which are disposed for frictional contact with the blanks.
- The flexible projections in friction means may, in one embodiment, be supported by a rotary central shaft whose axis of rotation is at right angles in relation to the direction of advancement of the blanks and in relation to the bottom of the magazine.
- In a further embodiment, the friction means may display bristles for contact with the blanks.
- For instance, the friction means may display rotationally formed brushes with long or short elastic projections protruding from a rotary core, for example a shaft or cylinder or the like, or from a belt in a web or similar carrier.
- Other constructional and detailed solutions than those listed here may also come into question in each specific case for reducing the present invention into practice.
- One embodiment of the present invention will be described in greater detail hereinbelow, with reference to the accompanying Drawing in which identical or similar parts have been given the same reference numeral. In the accompanying Drawing:
-
FIG. 1 schematically shows one example of a magazine provided with an apparatus exemplifying the present invention. - With reference to
FIG. 1 , this FIGURE shows one example of amagazine 1 with flat-foldedpackaging blanks 2 disposed standing on end in a queue or file with an edge portion against thebottom 3 of the magazine, one blank after the other, and in mutual contact by means their major surfaces. - The
blanks 2 are driven forwards through the front end of themagazine 1 by means of tworotary brushes 4 which are disposed on opposing sides and which, by frictional engagement with someblanks 2, urge them forwards. - In order to supply the rotating
brushes 4 withnew blanks 2 from the rear section of themagazine 1, there is provided a pusher orcarrier 5 which, from behind, applies a pushing force Fl against the last blank 2 in themagazine 1 in order to overcome any possible friction against themagazine 1 and ensure a continuous supply ofblanks 2 to thebrushes 4. - The advancement of the
blanks 2 through themagazine 1 has for its purpose to urge the leading blank in themagazine 1 against astop 6 and align it in a position from which it may subsequently be discharged out of themagazine 1 by means of asuitable discharge device 7. Further, the purpose is that a subsequent blank be placed forthwith in this position after the preceding blank has been discharged. - The
discharge device 7 normally displays some form of carrier which, by engagement with the blank in position for discharge (the leading blank) and displace it out of themagazine 1. In the example illustrated inFIG. 1 , this is shown by means ofcarriers 8 disposed at anendless chain 9 driven about two sprocket wheels. Thecarrier 8 is disposed to enter into engagement with an edge portion of the blank located in the discharge position (disposed against the stop 6) and displace it in the lateral direction through adischarge gap 10. When the blank has passed through thegap 10, it is grasped between twofeeder wheels 11 which move the blank further, for example towards a packing machine for raising, filling and sealing. - There are many technical solutions obvious to the skilled reader of this specification of how the discharge out of a
magazine 1 takes place, for which reason these will not be discussed in greater detail here. However, a feature common to most discharge devices is a wish that the blank 2 which is in turn to be discharged out of themagazine 1 be located in a predictable and predetermined position every time. - By disposing the rotating
brushes 4 in the forward region of themagazine 1 and in register with one another on either side of the queue of file of blanks, with a limited number ofblanks 2 between thebrushes 4 and thestop 6, those blanks which are located ahead of thebrushes 4—in thefirst pressure zone 12—will be acted on dynamically by an elevated pressure which is moreover self-adjustingly uniformly distributed between the sides of theblanks 2 and thereby in a position to even out any possible pressure variations from earlier positions in themagazine 1 and ensure that the first blank abuts correctly against the abutment points of thestop 6. - Too few blanks in the
forward pressure zone 12 may over form and create instability, while too many blanks entails an inertia so that the dynamic orientation and reforming of the queue of file in theforward pressure zone 12 will not occur. - The selection of brush radius also sets a mechanical limit for how close to the
stop 6 which thebrushes 4 may be placed. - In one embodiment, a few tens of
blanks 2 may be disposed ahead of the centre of thebrushes 4 and the number of blanks in therear zone 13 is of minor importance. In the embodiment according toFIG. 1 , there are approx. 50 blanks in theforward pressure zone 12. - By the formation of the
forward pressure zone 12, the pressure variations which occur often in prior art magazines between the abutment points of the front blank against thestop 6 can be handled and overcome. These pressure variations normally occur as a result of the fact that the blanks are not always entirely planar but may display thickness variations (in their turn because of, for example, folds or splices) across their extent. Since the blanks lie identically oriented after one another, a variation in thickness between the sides of a blank will be added by the number of blanks in the queue and the queue will deviate of and form an arc. - Compared with a traditional magazine of similar type with only advancement of the
blanks 2 by means of arear carrier 5, it is that force which thecarrier 5 applies on the last blank in themagazine 1 is very low. Thecarrier 5 does not directly contribute in abutting and aligning that blank which is to be discharged in a position against thestop 6, but only to advance the blanks to a position where thebrush 4 can reach them. - This also entails that a magazine according to one embodiment of the present invention may be replenished (in the rear region on the magazine) in that the
carrier 5 is reversed andnew blanks 2 are added, while thebrushes 4 continue to ensure that theblanks 2 in theforward zone 12 maintain their mutual pressure and ensure advancement and positioning of the front blank in position for discharge. The time that is available for this replenishment depends, on the one hand, on the discharge speed from themagazine 1 and, on the other hand, on packaging thickness and the number ofblanks 2 which thebrush 4 simultaneously can be in contact with. In that thebrushes 4 display a higher peripheral speed v1 than the advancement speed VM of the blanks, thebrushes 4 will, when themagazine 1 once again suppliesnew blanks 2, be capable of resetting and filling up the gap which has been formed in themagazine 1 during the replenishment. - Of some importance in this embodiment is that the pressure is uniformly distributed on both outer sides of the blank in order to achieve as good an abutment as possible between the first blank and the
stop 6. In particular at the sides, on passage where the blank is to move out through agap 10 and on the other side where the carrier is to enter into engagement with only this blank. - Advantageously, there may also be provided in the forward zone 12 a guide from above which presses down the
blanks 2 that are not in contact with thebottom 3 of themagazine 1. This guide is advantageously a sliding surface which operates by shaking or vibration. - The side walls of the
magazine 1 may be provided with apertures for the rotatingbrushes 4. - The side walls of the
magazine 1 may also be designed with limited extent in the vertical direction so that the blanks are accessible, for example that the side walls are rod-shaped in which event abrush 4 may be divided into sections but driven about the same axis of rotation and act below and above the rod-shaped side wall, respectively. - In the illustrated embodiment, the brush has a diameter of 80 mm.
- The
brush 4 displays a contact zone against the file or queue of blanks which is capable of achieving the sought-for pressure increase. The reason for this is that if a pressure increase does not take place, the rearwardly positioned blanks in the file or queue will affect the guiding/orientation all the way up to the stop. In other words if the pressure from behind is as great as in the forward pressure zone 12 (that which thebrushes 4 generate) no pressure increase will be created and then the first blank cannot be correctly oriented by being completely urged against thestop 6. - In the embodiment illustrated in
FIG. 1 , brushes 4 are used as examples of friction means for picking or rifflingblanks 2 forward to theforward pressure zone 12 and realising the pressure increase. Other embodiments of friction means may include elastic projections, for example rubber fingers, impeller-like blades or the like which form a friction contact against some blank in the file or queue and which is driven by suitable drive means, such as a drive shaft, belts, linkage arms or the like which are employed. - The present invention should not be considered as restricted to that described above and shown on the Drawing, many modifications being conceivable without departing from the scope of the appended Claims.
