No. 236,258 Claims priority, application Sweden, Nov. 21, 1961, 11,560/ 61 3 Claims. (Cl. 83-98) This invention relates to an arrangement for removing the tobacco waste which occurs in cigar machines at the end of a web of tobacco sheet material when cutting wrappers or binders from the web of tobacco. The strip of tobacco is arranged to be fed forward in steps on a cutting bed provided with perforations, on the underside of which cutting bed there is arranged a chamber connected to a suction pipe and in which a cutting die with a width corresponding to the width of the web of tobacco is situated.
An object of the invention is to provide an arrangement of the stated kind which is both simple and reliable and which ensures the removal of tobacco waste even in the event of tobacco waste adhering at some point to the cut out wrapper or binder or becoming attached to the cutting bed or cutting die. According to the invention this is achieved by the cutting bed with its underlying chamber being divided into two separate parts by the cutting die, a part of the cutting bed lying farther away in relation to the feeding direction being arranged to be pivoted outwards from the cutting die to an inclined position and thereafter returned again to the starting position after every cutting operation by means of an actuating mechanism, and by a valve device controlled in synchronism with the pivotal movement being arranged to break off the suction effect of the suction pipe through the perforations of this part during at least that portion of the movement when the inclination is greatest.
During the first part of the pivotal movement the tobacco waste thus is secured to the pivotal part of the cutting bed by the suction action, any tobacco waste being drawn olf. In one particular embodiment of the invention tobacco waste is removed even when it adheres to the cutting bed and remains there despite the pivoting of the cutting bed to the inclined position as in this position the chamber is connected to a pressure pipe so that eventually adhering tobacco waste is loosened by the stream of air through the perforations of the cutting bed.
An embodiment of the invention will now be described by Way of example with reference to the accompanying drawings, in which:
FIGURE 1 shows a horizontal view of the arrangement,
FIGURE 2 shows a vertical section of the pivotal part of the cutting bed taken along the line 11-11 in FIG- URE 1', and
FIGURE 3 shows a vertical view of the arrangement, partly in section.
The cutting bed comprises a fixed part consisting of a perforated plate 1 and a non-perforated plate 2, and a movable part consisting of partially perforated plates 3. The cutting bed encloses a likewise perforated cutting die 4 which is provided with a knife blade 5 corresponding to the contours of the wrapper or binder. On the underside of the perforated plates 1, 3 and 4 are arranged chambers connected to a suction pipe. The movable part 3 of the cutting bed with its two underlying chambers 13 is secured to a pivotally mounted shaft 7 in a frame 6. The interior of each of the chambers ice 13 is connected to a suction pipe via an opening 8 between the chambers and a channel 9 arranged in the shaft 7. The channel terminates in an opening 14) through the Wall of the shaft where a sleeve 11 is arranged, which sleeve encloses the shaft and has a passage 12 connected to the suction pipe. The opening 1! and the passage 12 are located directly in front of each other when the movable part 3 of the cutting bed is in its starting position, FIGURE 2, but in the pivoting of the shaft 7 to the perpendicular or maximally inclined position of the part 3 the opening 1% is situated completely to one side of the passage 12, the suction action through the perforations of the part 3 thus being interrupted.
The chambers 17 and 18 located on the undersides of the perforated plates 1 and 4, respectively, are connected to a suction pipe 19 via a valve 20 operated by an actuating mechanism, not shown, adapted to connect the chambers 17, 18 with the suction pipe 19 during the cutting operation and the pivoting operation of the parts 3 for retaining the leading end portion of the web on the plates 1, 4 during these operations.
The web 21 of tobacco is wound on a roll 22 and is fed forwards in steps over the cutting bed in the direction indicated by an arrow in FIGURE 1 by means of a web carrier member 23 operated to and fro over the cutting bed by means of a cam operated fork 24. The end portion of the web 21 is gripped in any suitable, known manner by the carrier member 23 e.g. by suction action or in the manner disclosed in US. Patent 3,149,767 granted September 22, 1964 and moved forward over the cutting bed. The end of the strip, whose contours correspond to the contours of the front part of the knife 5, is placed with its corners on the movable part 3 of the cutting bed and with a narrow strip of its middle part on the plate 2. The cutting of a wrapper or binder then takes place in the normal manner, the tobacco sheet being pressed against the knife edge 5 of the cutting die by means of crosswise moving rollers, schematically indicated at 25 in FIGURE 3, whereby the end portion on part 3 and plate 2 is separated from the cut out wrapper or hinder on the cutting die 4. The shaft 7 is then pivoted by means of an actuating mechanism not shown, which acts together with an arm 14 attached to the shaft 7. During the first portion of the pivoting of part 3 towards the position of maximum inclination the tobacco waste is secured to the part 3 and the wrapper or binder is secured to the cutting die 4, because of the action of the suction pipe through the respective perforations, and portions which happen to adhere because of incomplete cutting are drawn off. At a predetermined angle of inclination the suction action through the perforations of the part 3 is interrupted because of the switching of the valve device 10, 11, 12 and the tobacco waste slides down or is thrown off from the cutting bed 3.
In order to prevent the tobacco waste from becoming attached to the cutting bed 3 for any reason and following it back to its starting position, the sleeve 11 can be provided with another passage 15 which is connected to a pressure pipe and which is arranged to terminate directly in front of the opening It in the shaft 7 when the cutting bed 3 is in the position of maximum inclination.
The invention is not limited to the embodiment shown here but can be varied in several different ways within the scope of the invention. Thus the movable part 3 can be embodied as a continuous part and include part 2. Moreover, the connection of the suction pipe and pressure pipe to the movable part 3 of the cutting bed can be made of flexible tubing with separately actuated valves synchronised with the pivoting of the part 3. In many cases it can also be advantageous to arranged the pivotal shaft of the part 3 a little below the plane of the cutting bed so that Simultaneously with the pivotal movement a movement outward from the cutting die 4 is imparted to the part 3.
What is claimed is:
1. In an apparatus for severing wrappers or binders from the leading end portion of a web of tobacco sheet material, the combination comprising a first perforated plate having a web supporting surface, a second perforated plate having a web supporting surface spaced from said first perforated plate, a third perforated plate having a web supporting surface between said first and second plates, a cutting knife surrounding said third plate having a contour corresponding to the contour of said Wrappers or binders, means for moving the leading end portion of the web across said plates to place the ending end edge of the web upon said second perforated plate, suction means for retaining the leading end portion of the web upon said perforated plates, means cooperating with said knife for cutting the web, means for pivoting said second perforated plate out from said third perforated plate and a valve device operated in synchronism with said pivoting means to break off the suction effect of said second perforate-d plate during at least a part of the pivotal movement.
2. An apparatus as claimed in claim 1, wherein a rotatably mounted shaft having a channel is provided to which said second perforated plate is secured, said second plate having a chamber secured to the underside of said plate connected to said channel, said shaft having an opening, a sleeve connected to suction means enclosing said shaft having a passage through the wall thereof located in front of said opening in said shaft when said second perforated plate is in its starting position.
3'. An apparatus as claimed in claim 2 wherein said sleeve is provided with another passage located in front of said opening in said shaft connected to pressure means when said second perforated plate is in inclined position.
