Closure plates for a coin stacking tube one Coin wrapping machine

The invention relates to closure plates for a coin stacking tube a coin wrapping machine.

In a typical coin wrapping machine, the flap plates are relatively thick plates (generally about 3 mm thick) in order to be able to withstand the impact of the coins falling on them. The upper end of a support rod is arranged just below the lower surface of the closure plates, onto which the coins fall over a distance of about k to 5 mm when the closure plates are opened. The support rod has a smaller diameter than the coins at its upper end. Therefore, when the coins fall on the support rod, they may slide relative to the support rod or, what is worse, slide down from the upper end thereof. In the case of coins displaced with respect to the support rod, the stack of coins can collapse during the downward movement of the support rod when the wrapping roller is touched, so that coins fall down and are scattered and have to be collected. In this case, the operation of the machine must be stopped so that its productivity is lowered.

The object of the invention is therefore to create an improved closure of the type mentioned above

Disadvantages eliminated.

The invention consists in closure plates for opening and closing a coin stacking tube at the lower end thereof in that the closure plates in areas with the upper end of the for moving the in the coin stacking tube stacked coins in the gap between the wrapping rollers correspond to the support rod, are formed with continuous recesses or on the underside with a recess, so that the upper End of the support rod on the underside of the stack of coins in the through recesses or depressions Approved measure approach canoe.

Embodiments of the invention are described below with reference to the accompanying drawings. In these shows

In the known coin wrapping machine shown in Fig. 1, coins of a denomination are wrapped in a not shown Coin counting part is separated from the coins of other denominations and counted and then they are placed in a stacking tube 1 stacked. Located just under the stacking tube 1

UerschluBplatten Za ₁ 2b, which can support the coins, bo that they can be temporarily stored in the stacking tube 1. The lock plates 2a, 2b consist of hoarded steel plates and have a uniform thickness and are attached to curved pieces 2a ¹ , 2b ¹ with which the lock plates can be moved in opposite directions for opening and closing. For this purpose, the cam piece 2a ^{1 is} connected to an electromagnet k by a lever 3. The device for opening and closing the lock plates can, however, also be designed differently than described above. For example, an electric motor and / or gears can also be used to open and close the lock plates. A tension spring 5 seeks to move the lock plates 2a, 2b into the closed position shown in FIG. 1 when the electromagnet k is de-energized. Wrapping rollers 6, 7, B, of which at least two are rotatable, are arranged just below the closure plates 2a, 2b, and a support rod 9 is also arranged, which can be moved up and down in order to receive a stack of coins a from the inside of the stacking tube 1 and to move this stack of coins between the wrapping rollers, because the coins are completely wrapped, the support rod can be pulled off the wrapping rollers. Wrapping claws, not shown, are also provided, which serve to wrap the opposite end portions of a piece of wrapping paper when the coins are being wrapped.

Coins counted in the counting part are put into the stacking pipe 1 introduced. The stacking tube 1 and the lock plates 2a, 2b are thereby moved by a vibrating device (not shown) vibrated horizontally and vertically so that the

Coins occupy a uniform position. When coins have been counted in the number to be wrapped in a roll, the counting operation in the counting part is interrupted. When the coins are stacked correctly, the support rod 9 is moved to just below the closure plates 2a, 2b. In the correct temporal relationship to the arrival of the support rod 9 just below the closure plates 2a, 2b, the electromagnet h is switched on, which now opens the closure plates 2a, 2b so that the stacked coins fall onto the support rod 9.

The support rod 9 supporting the stack of coins a is now moved downward between the wrapping rollers 6, 7, 8, the then attack the stack of coins under pressure so that it is rotated and wrapped in a piece of wrapping paper is wrapped in a predetermined format. This is then hammered in at its opposite ends and closed. Now the stack of coins is wrapped. The closure plates 2a, 2b are relatively thick (generally about 3 mm), so that they meet the impact of the falling Coins have grown. The upper end of the support rod 9 is up kiaapp under the lower surface of the locking plates 2a, 2b moved upwards, so that when the closure plate is opened Coins over a distance of about if to 5 mm fall. The support rod 9 is smaller in diameter at its upper end than the smallest coin.

The closure plates of the known coin wrapping machine have the aforementioned disadvantages.

Preferred exemplary embodiments of the invention are described below with reference to FIGS. 2 and 3. Diectort Shown closure plates 2, 2 »are in areas that correspond to this when the support rod 9 is raised,

with continuous recesses 10 'on the underside formed with l / 1D depressions. Consequently the upper end of the support rod 9 can be bent up closer to the lower surface of the coin stack uerden than according to the prior art, so that the stacked Coins only over a very short distance the support rod fall and therefore a collapse of the Coin pile can be avoided.

The mechanical strength of the closure plates 2, 2 ^{1 is} not reduced, as would be the case if very thin closure plates were used. Faults that cause business interruptions occur less often, so that the invention represents a significant technical advance.
