Description

Method and plant for transpor ng stacks of shred-shaped label blanks on an accumulating conveyor
The invention relates to a method for transporting stacks of shred-shaped label blanks on an accumulating conveyor for conveying of stacks, one at a time, to a table from which they are conveyed to a cutting station.
By a known method of this kind each shred stack is, during the whole transport and the final cutting, placed on a piece of cardboard which protects the thin label blanks from being mechanically damaged during the accumulating process The placement and removal of these pieces of cardboard are, however, time- and labor-requiring operations, which will delay and rise the price of the whole process, and therefore the invention has the purpose of providing a method of said kind which makes it possible to avoid the use of carrying pieces of cardboard.
This purpose is obtained by the fact that there during the transporting of each stack is blown air up against its bottom side in order to produce a supporting air cushio an that stack thus airborne is pushed along the conveyor. Thereby the label blanks, without the conventional base of cardboard, will be efficiently protected from being damaged by mechanical contact with a conveyor band as at the same time is stopped.
Approbiate embodiments for the method according to th- invention is stated in the claims 2, 3 and 4.
The invention also relates to a plant for carrying-out: said method comprising an accumulating conveyor for conveying stacks of shred-shaped label blanks from an inlet end forward to a receiving table, and the characteristic of the plane according to the invention is that the conveyor consists of one or more conveyor bands having holes and that there oeneatn the conveyor is placed an air exhaust nozzle which is movable along the conveyor and also one or more pushing means which are adapted for pushing shred stacks along the conveyor on an air cushion produced by the air nozzle.
Due to the fact that there immediately beneath the upper conveyor path and immediately above the lower conveyor path is placed a stationary top plate and bottom plate, respectively, provided with holes, and that there between and mainly at right angles to these plates extend conveying plates for concentrating the air stream from the nozzle against the superjacent stack, it is obtained that the greatest possible part of the produced air stream is utilised for producing the supporting air cushion.
Other approbiate embodiments for the plant according to the invention is stated in the claims 7 - 10.
The invention will be more fully explained below with reference to the drawing, in which
Fig. 1 is a schematical wiev, seen from above, of a label processing plant comprising an accumulating conveyor,
Fig. 2 shows in a perspective picture a part of an embodiment for a section of the accumulating conveyor according to the invention,
Fig. 3 shows a vertical longitudinal section through the accumulating conveyor, and
Fig. 4A - 4E show schematically longitudinal sections through the accumulating conveyor in different stages of its function.
In fig. l is 10 a table on which a stack of sheet-shaped label blanks 11 is resting, each blank consisting of a number of singular stacks, in the example shown 6 x 4 = 24, with labels
12. These blanks are conveyed to a not shown cutting machine which separates them into stacks 13 of shred-shaped blanks, which stacks, one at a time, are placed upon an angular shaped feed table 14, which is placed at the inlet end of an accumulating conveyor 15 and an auxiliary conveyor 16, from which the stacks are delivered to a receiving table 17. From this table the shred stacks are conveyed to a not shown cutting machine which separates them into stacks of singular label blanks 18 which again are conveyed to a punching machine 19 which punches the actual labels 12 which finally are stacked in a stacking machine 20.
As it will be seen from the following description of the accumulating conveyors 15,16, an operator who notes that the main conveyor 15 is empty or just about to be empty, will feed this conveyor with a number of shred stacks 13, which one by one, after having been placed on the feed table, will be conveyed by a transporting mechanism, not shown in fig. 1, to a position at a distance pre-decided to the rear of the stacks already lying on the conveyor. When in this way a suitable number of shred stacks 13 on the conveyor 15 and a stack lying on the receiving table 17 is removed the transporting mechanism will pick up the front stack on the main conveyor 15 and convey it to the table 17.
As shown in fig.l the main conveyor as well as the auxiliary conveyor 16 are divided into three parallel sections 15a, 15b, 15c and 16a,16b, 16c, respectively, juxtaposed with small interspaces 21, and as it will appear more clearly from tne following, the transporting mechanism comprises pins 22 and 23 (fig. 2, 3 and 4) which can be brought to extend up through the interspaces 21 and move along these.
Each section of the main conveyor 15 consists of a band 25 formed with holes 24 close together of nylon or similar material running about a driving roll 26 and an idler roll 27
Beneath the conveyor there is placed a conveying unit whicn generally is designated by the reference numeral 28, and which comprises a box-shaped air exhaust nozzle 29 extending across the conveyor and like this is divided into three sections, and also two pneumatic cylinders 30 being placed each opposite the interspaces 21 between the conveyor sections. Each cylinder 30's piston is connected with a conveying pin 22, and each section of the air nozzle 29 is supplied with compressed air via a tube 31. The with of the air nozzle, that is the dimension of the conveyor's longitudinal direction, is principally adjustable in a way not shown.
The transporting unit 28 is movable along a guide 32 which extends along the whole length of the conveyor.
Between the forward motion band and the return motion band of each transporting section there is placed an air distribution box which consists of a top plate 34 made of steel or similar material provided with oblong holes 33 and also consists of a bottom plate 36 provided as well with oblong longer holes 35 and side walls 37. Between the top plate 34 and the conveying band 25 there might be placed a perforated upper plate 38 which can be movable in relation to the top plate fox- regulation of the air flow. Between the top plate 34 and the bottom plate 36 there are placed a number of partition walls 39.
Transportation of a shred stack 13 on the main conveyor 15 takes place when the transporting unit 28, controlled by a not shown control unit, is placed beneath the stack which thereby will rest on an air cushion which is formed by the air streaming out of the nozzle 29, and then the two transporting pins 22 are shot up behind the stack by activation of the cylinders 30, and the transporting unit 28 is moved slowly along the convey 32 by means of a suitable, not shown, moving unit, which for example can be a transporting band or a rack and pinion. During this whole transportation the shred plate is resting on a wandering air cushion without coming into contact with the conveyor as at the same time is stopped.
The short auxiliary conveyor 16, which has been placed between the main conveyor 15 and the receiving band 17, is not shown in details, but is constructed in a similar way as the main conveyor and just like this 42 it has along a guide a movable transporting unit with not shown air nozzles and pneumatic cylinders 40 with transporting pins 23. The auxiliary conveyor's band 41 is running over a driving roll 43 which is situated close to the driving roll 26 of the main conveyor and which also has a idler roll 44 divided into sections.
Fig. 4A shows how shred-shaped stacks label are feeded onto the main conveyor 15. As mentioned, both the idler roll 27 and the angular feed table 14 are divided into sections, so that the transporting pins 22, which by means of the transporting unit 28 can be conveyed back to a position behind the feed table 14, can pass through the roll 27 and the feed table thereby pushing the stack lying on the table down upon the conveyor and forward to a position at a pre-decided distance from the rear of the stacks already lying on the conveyor.
When the receiving table 17 is empty, the transporting unit 28 will place itself in a position beneath the front stack on the conveyor as shown in fig. 4B. This stack do not have to be at the outlet end of the conveyor, as shown, but can be in any position anywhere on the conveyor. When arrived at the position mentioned, the unit 28 will shoot its pins 22 up behind the stack and convey this forward to the position as shown in fig. 4C where the pins are situated just next to the joint shaft 45 of the driving rolls 26.
In this position the stack 13 is resting lightly on both conveyors due to the fact that it still is supplied with a supporting air stream from the air nozzle of the main conveyor, and by starting the two conveyors the stack is conveyed forward to the position on the auxiliary conveyor as shown in fig. 4D where the transporting unit of this latter can shoot its pins 23 up behind the stack and convey it over upon the receiving table 17, which, as shown in fig.l, is formed with slits 46 for taking up the pins 23, as shown in fig. 4E.
The invention is not limited to the embodiment shown in the drawing and described above, since the details in this can be changed in several ways. Thus it is possible, for example, to let out the auxiliary conveyor when the main conveyor's driving roll is placed somewhat behind the feed table 14, and in this way the transporting pins can be shot up between this roll and the table, and the idler roll at the outlet end can be divided into sections so that the pins can pass between them into the receiving table.
