In order that the angle between the web 1 and the blade 3 remains constant when the relative position of the blade 3 with respect to the packing rollers 13 is changed to alter the length of web cut, the blade 3 and the feed rollers 23, 24 are mounted for conjoint movement about an axis 15. A lever 21 permits adjustment of the cutter blade 3 so that the mechanism can cut off the different lengths of material for different diameters of coins. <IMAGE>
Description
SPECIFICATION
A packing material cutting mechanism of a coin packing machine
The present invention relates to a coin packing machine, and more particularly to improvements in a packing material cutting mechanism used in such a machine.
In a coin packing machine packages of coins are produced by winding packing material, for example paper, around the circumferences of piles of coins and then folding the packing paper tightly at both ends. In a machine ofthis kind, a preset length of packing paper is unrolled by means of feed rollers and the paper is guided around the circumference of the piled coins and wound around the piled coins by means of packing rollers. The packing paper is put in tensions between the feed rollers and the packing rollers, when it is to be wound around the piled coins by the actions of the packing rollers. As a result, the packing paper is straightened and forced against the edge of a cutter so that it is automatically cut. One of the most important factors to be considered in this cutting operation is the angle at which the packing paper abuts the cutter edge.If the diameter and/or thickness of the coins is varied in accordance with various denominations of coins, then it is necessary to change the length and/or width of the paper to be used for the packing operation. The cutter is shifted in orderto change the length of the packing paper which is cut.
However, since the feed rollers are at preset positions, when the position of the cutter is shifted to adjust the cut length of packing paper the relative positions of the feed rollers and the cutter are changed making the cutting angle of the packing paper more obtuse which can result in unsatisfactory cutting.
The present invention provides a packing material cutting mechanism of a coin packing machine, in which the position of a cutter is set in accordance with the diameter of a pile of coins to be packed, the spacing between the cutter and a plurality of packing rollers determining the cut length of a web of packing material, comprising: a driven feed roller disposed to move together with said cutter, while maintaining its relative position to the same; and an idler feed roller, the web running between the feed rollers so as to supply the packing material towards said cutter.
In one embodiment of the invention the mechanism comprises a plurality of packing rollers arranged to wrap a pile of coins with a cut portion of a web of packing material which is supplied from between a pair of feed rollers, and a blade between the feed rollers and the packing rollers disposed so that an increase of the tension of the length of web between the packing and the feed rollers causes the blade to sever the web, the blade and the feed rollers being mounted for conjoint movement so that during alteration of the cut length of the web by adjustment of the position of the blade relative to the packing rollers the angle between the web and the blade remains constant.
The packing material can be paper.
The present invention will now be described by way of an example with reference to the accompanying drawings, in which:
Figure 1 is a top plan view showing a known packing paper cutting mechanism for use with a coin packing machine with a view to illustrating the background of the present invention;
Figure 2 is a simplified perspective view showing in an exploded manner a packing paper cutting mechanism according to the present invention together with such essential portions of the coin packing machine as are necessary for explaining the construction and operations of the packing paper cutting mechanism of the present invention;
Figure 3 is a top plan view showing the packing paper cutting mechanism, as shown in Figure 2, according to the present invention; and
Figure 4 is similar to Figure 3 but shows the case, in which the size of coins to be packed is reduced.
Before entering into the detailed description of the present invention the packing paper cutting mechanism of a known coin packing machine will be explained for illustrative purposes only with reference to Figure 1. As shown, the packing paper cutting mechanism is equipped with a pair of feed rollers 2 which are made operative to let off a roll of packing paper 1. The feed rollers 2 are attached to the (not shown) frame of the packing machine in the vicinity of the rolled packing paper 1 so that their position is fixed. As a result, when the position of a cutter 3 is shifted to adjust the cutting length of the packing paper 1,the relative position of the feed rollers 2 and the cutter 3 is changed.More specifically, when the contact position between the packing paper 1 and the cutter 3 is shifted towards a pile of coins 4 until it is in a position shown in doubledotted lines, the cutting angle of the packing paper 1 by the cutter 3 becomes more obtuse so that the packing paper 1 cannot be cut in a satisfactory fashion.
Turning now to Figures 2 to 4, which show a cutting mechanism in accordance with the present invention. Indicated generally by 10 is a cutting mechanism exemplifying the present invention, which corresponds to the cutting mechanism 5 shown in Figure 1. The cutting mechanism 10 is interposed between the rolled paper 1 and three packing rollers 13. The cutting mechanism 10 has its shaft 15 rotatably supported on a pair of supporting members 14 which in turn are fixed to the (not shown) body of the packing machine. A pair of rocking members 16 are mounted rotatably to the upper and lower end portions of the shaft 15. The cutter 3 carrying an auxiliary guide plate 17 is fixed to the leading ends of the rocking members 16.
There is also fixed to the leading ends ofthe rocking members 16 a guide plate 19 which is positioned at a slight distance from the edge of the cutter 3. There is fixed to the other end of the lower rocking member 16 a rocking arm 21 which is movable along a scale plate 20. The rocking arm 21 is equipped at its leading end with a knob 22.
A drive roller 23 is mounted rotatably between the rocking members 16 of the cutting mechanism 10.
An idler or follower roller 24 is mounted rotatably between a pair of arm members 25 which are also mounted rotatably to the upper and lower end portions of the shaft 15. The follower roller 24 thus mounted is biased into contact with the drive roller 23 by means of a not shown spring so that the former roller 24 can rotate, driven by the latter roller 23. A driven gear 26 is mounted to the upper end portion of the drive roller 23 and is driven by a drive gear 27 which in turn is mounted to the upper end portion of the shaft 15. An intermediate gear 28 is interposed to mesh between the two gears 26 and 27. To the lower end portion of the shaft 15, on the other hand, there is mounted a driven gear 30 which is driven to rotate through an intermediate gear 29 by a driving power source such as a not-shown motor.Incidentally, reference numeral 31 indicates a guide roller which is operative to guide the packing paper 11, when the latter is unrolled, to the cutting mechanism 10. Moreover, indicated at numeral 32 is a guide wall 32 which is positioned upright to guide the packing paper 1 to the packing rollers 13.
The operations of the cutting mechanism thus constructed will be described. At first, the packing paper 1 is unrolled by progressively pulling its leading end and it is threaded into the clearance between the drive roller 23 and the follower roller 24.
The leading end of the unrolled paper 1 is further introduced into the clearance between the cutter 3 and the guide plate 19. After this preparation, when the piled coins 4 are carried into the space between the packing rollers 13, the drive roller 23 is turned by the not shown power source through the gears 29, 30, 27, 28 and 26 in this order. As a result, the packing paper 1 is progressively let off, while being held between the drive roller 23 and the follower roller 24, so that it is guided by the guide wall 32 onto the piled coins 4. Then, the packing paper 1 thus guided is wound on the outer circumferences of the piled coins 4 by the actions of the packing rollers 13. After a preset time lapses, the driving power is interrupted to stop the drive roller 23 so that the let-off operation of the packing paper 1 is interrupted.Since this paper 1 is held between the two rollers 23 and 24 and since the packing rollers 13 still continue their rotational packing operations, the packing paper 1 is still held under tension by the pulling forces of the packing rollers 13. As a result, the packing paper 1 is forced onto the edge of the cutter 3 until it is cut thereby. The packing paper 1 thus cut is wound on the piled coins 4 and then is closed tight at both ends.
If it is desired to change the cutting length of the packing paper 1 in accordance with the diameter of the piled coins 4, the rocking arm 21 is manually moved along the scale plate 20 to rock the lower rocking arm 16 about the shaft 15 so that the cutter 3 may be carried by the rocking members 16 until the cutter 3 is brought to such preset position as can cut the packing paper 1 to a preset length. At the same time as the cutter 3 is moved both the rollers 23 and 24 are moved together. As a result, the packing paper 1 is guided by the rollers 23 and 24 at a preset satisfactory angle with respect to the cutter 3 so that its cutting operation can be ensured irrespective of its cutting length.
The movement of the cutter may be carried out in cooperation with a known denomination selecting handle operated to select a desired kind of coin.
