Cut off length.

In the previously customary multi-purpose wrapping machines a system commonly used in which the wrapping paper strip wound into a roll is inserted into the wrapping mechanism is drawn in, with the front end of the fed strip between the in the wrapped position The stack of coins in the wrapping mechanism and several winding rollers that rotate the stack of coins are jammed so that the wrapping paper is wrapped around the stack of coins and is stretched in the process can so that it is pressed against a cutting device which is located near the paper feed path, whereby the Paper is cut as it is wrapped around the stack of coins.

In one such known system, the length of the cut is The wrapping paper strip is determined by the distance between the cutter and the wrapping mechanism, and therefore the positions of this and other mechanisms are naturally constrained. If in addition the wrapping paper is wrapped around a stack of coins while being separated by stretching, then becomes light the feed direction of the cut paper strip between the stack and the winding rolls by the train at the moment

of cutting off, so that the piece of wrapping paper is wrapped around the stack of coins improperly, resulting in The result is that the stack is not properly sealed at both ends.

The aim of the invention is therefore to eliminate this disadvantage, which is why an improved cut-off and providing a feeder which cuts a piece of strip from a long tape of wrapping paper and this Strip piece feeds and an additional wrapping paper feed mechanism comprises between the cutting device and the pile wrapping mechanism, whereby a Wrapping paper strip piece of the desired length is obtained by cutting the wrapping paper while it is from It is then fed into the coin wrapping mechanism.

Due to this structure, it is possible to use the wrapping paper carrying device of the wrapping mechanism in different positions, and also because the wrapping paper is in If the winding mechanism is entered after it is cut into pieces, it is possible for the winding mechanism to also skew To prevent strip pieces during the wrapping.

Viewed as a whole, it is possible with the invention, the position for the attachment of the wrapping paper strip in Regarding the stack wrapping mechanism to be chosen freely, so that the construction of a coin stack wrapping machine thereby is much easier, and also because the already cut strip of wrapping paper in the When the winding roller device is entered, there is no obstacle to the winding of the coin stacks being carried out one after the other without unpleasant displacements of the pieces of paper strips, so that perfectly wrapped Coin rolls emerge from the machine.

The invention is now shown in conjunction with an exemplary embodiment explained again with the drawing. Show it:

As shown in Fig. 2, the inserted wrapping paper is bent by a paper guide plate 112 with Form passed into a paper clamping mechanism 113, the is arranged at the output end of the guide plate 112.

This clamping mechanism 113 shown in FIG. 3 has two vertically spaced rollers Il4 and 115 * which are rotatably supported in the frame of the machine (not shown) and which have a large number of endless belts II6 that run parallel to each other around these rollers. The belts II6 are tensioned by a tensioning roller 117, that presses on the side. Two vertically spaced rollers 119 and 120 are provided for the belts II6, which are rotatably carried between two horizontal arms 118 and Il8a. Between the two rollers 119 and 120, a vertical guide plate 121 is provided, as shown in Fig. 2, which acts to move the wrapping paper 58 guided against the surfaces of the belts II6 and is guided by these along these surfaces.

The roller II9 has an axis 122 which can be rotated in the frame the machine (not shown) is supported, and the state of contact or the distance of the roller 120 relative to the belts II6 is set by an adjusting screw 123 and

- 6 -509 831/0010

a spring (not shown) set. A gear 125 is attached to the lower end of the shaft 124 of the roller 115 and is connected to the shaft 99 via a gear train, the gear train consisting of the gears 125, 126, 127, 128, 129, 130 and 131, the shaft 132 of the gear 131, a disk 133 fixed on the shaft 132 and a belt 134 extending between pulley 133 and a pulley 135 mounted on shaft 99. The shaft 99 is coupled to a motor (not shown).

The wrapping paper 58 passes through the tensioning mechanism 113 and becomes an egg wrapping or packaging mechanism 136 entered for coins, of the three winding rollers 137, I38 and 139 owns. The roller 137 becomes rotatable on an arm l40 and is an idle roller that can swing around a vertical axis l4l. The roller 138 is rotatable supported on the arm 142 and can around the vertical shaft

143 swing, which is a drive roller, which is its driving force from a gear 127 via a gear connection (not shown). The roller 139 is also rotatable supported on an arm (not shown) around the shaft

144 of the gear 127 can swing, and provides a drive roller which is driven by the gear 127 via a transmission (not shown).

The wrapping paper 58 fed in from the tensioning mechanism II3 is guided by parallel, separate paper guides 145 and 146 which are fixedly attached to the frame of the machine (not shown), and paper guides 147, 148, 149 and 150 which are suitable for the to move paper in a similar manner to the winding rolls 137 '138 and 139th

The device works in the following way. A coin selector (not shown) is operated to select the type of coin to be wrapped, and then to select one The switch (not shown) corresponding to this type of coin selected in this way is actuated to activate the coil 105 (FIG. 8 and 9) to excite so that the adjustment element moves to the left. The roller 97 then swings around the Shaft 99 and is lifted off roller 63.

In a way that is not of interest here, it becomes the corresponding one Roll of wrapping tape moved into working position.

When a start button (not shown) is then pressed for the wrapping process, the coil 105 is switched off, and the roller 97 is pressed against the roller 63. Thereon

- 8 50983 1/00 10

sorting and counting of coins is carried out, and a certain number of coins are put in the coin stacking mechanism piled up. The stack of coins thus formed is inserted into the coin wrapping mechanism by the guide rod 216 136 brought, whereupon a nooke of a cam group (not shown) actuates a switch that starts the coin wrapping notor (not shown).

The disc 135 * then rotates and becomes this Rotation via belt 134, pulley 133, gears 131, 130, 129, 128 and 127 and other gear parts (not shown) are transferred to the wrapping rollers 138 and 139. The wrapping rolls 137, 138 and 139 are also used by a lever mechanism (not shown) controlled by the cam group to engage the stack of coins C to apply.

The rotation of the shaft 99 of the disc 135 is applied to the drive roller 97 and the input rollers 62 and 63 are transferred, and the wrapping paper 58 is removed from the outer end of the cutter 64 steered to the paper guide plates 65 and 112 and thus enters the paper tensioning mechanism II3. At this point the spool 105 is energized by a cam (not shown) and the roller 97 rises from the roller

6j> from. Since the roller 115 of the tensioning mechanism 113 is driven by the force transmitted by the gears 127, 126 and 125, the belts 116 continue to move. Accordingly, the paper 58 is moved between the roller and belts 116 and toward the coin wrapping mechanism I36.

During this process, the tensioned paper between the cutting device 64 and the paper tensioning mechanism is pulled by the tensioning mechanism II3, and the tensioned part of the paper is thereby pressed against the cutting edge of the cutting device 6k and cut off there. This gives a piece of wrapping paper of a certain length which is adapted to the type of coin to be wrapped.

The leading edge of this piece of paper then enters between the winding roller 137 and the coin stack, whereupon the Wrapping rollers 137, 138 and 139, which hold the stack of coins between them, the wrapping paper around the cylindrical surface this coin stack by the rotation of rollers 138 and 139 wrap. The upper and lower side edges of the thus wrapped paper are folded on it, and the wrapped one The coin stack is then output.

At the end of this winding process of a stack of coins the coil 105 is switched off, and the roller 97 is against the input roller 63 in preparation for the next Paper input process.

Since the length of the cut piece of wrapping paper can be adjusted according to the type of coin to be wrapped must, the cutters. 64 on the paper input mechanisms Set in different positions depending on the type of coin. For example, referred to the reference numeral 64a a cutter for a different type of coin which is on a different paper input mechanism is appropriate. The distance between the paper spanning mechanism II3 and the cutting device differs 64 with the type of coin, and the length of the cut paper therefore also differ.

The leading edge of a piece of wrapping paper that has been cut by cutter 64 and for which the subsequent wrapping process is to be entered is at the location of the cutting device 64. In the same way, the leading edge of a through the Cutting device 64a cut paper in place of the cutting device 64a. The moments of the

- 11 509831/00 10

Enter the wrapping paper and the duration of the Wrapping processes must be the same.

It is therefore necessary to move the paper to and through the tensioning mechanism II3 at one speed to convey which is higher by a difference that the difference between the cutting devices 64 and 64a produced paper lengths corresponds, and regardless of the type of coin to ensure that the points in time essentially are the same in which the leading edges of the paper after passing through the tensioning mechanism in the area enter between wrapping roller 137 and coin stack C.

For this purpose, the speed of the Motors (not shown) for the wrapping process accordingly the type of coin to be able to change, whereby the speeds of the roller 97 and accordingly also the input rollers 62 and 63 can be changed. That means, the longer the cut length of the wrapping paper is, the higher the speed with which this is entered. Accordingly, the speed of the Belts II6 changed as well as the speed of the winding rolls 138 and 139. The reason for the change in the speed of the winding rollers 138 and 139 is that

- 12 509831/00 10

the times for wrapping the peripheral surfaces of the coin stacks through the paper should be essentially the same regardless of the type of coin.
