PATENT OFFICE.

The present invention relates to an automatic weighing machine for piece goods and bulk goods, too Liquids in which the whole weight is on the balance beam while the carriage is in motion loads and, after the corresponding item to be weighed has fallen, the weighing pan for further downward movement for this purpose more automatically Emptying by releasing part of the weighing weight BEZW. Shortening ίο the weight arm becomes overweight.

Fig. Ι shows the balance shortly before reaching the equilibrium position,

Fig. 2 in the equilibrium position and

Fig. 3 capable of emptying the weighing pan.

The weighing weight is formed by a weight 2 and the weight of the two levers 2 ¹ , 2 ² rotatably attached to the weights 2. A pin 15 is fastened at a corresponding point on the frame of the balance, against which the free end of the lever 2 ¹ rests before the balance reaches its equilibrium position. The lever 2 ¹ is usually with its ^{lugs 2 3} in engagement with a similar lug 2 * of the lever 2 ² and thereby holds the latter in the position shown in FIG.

Immediately before the balance beam 1 reaches the equilibrium position, the pin 15 holds the free end of the lever 2 ¹ back, so that the latter swings around its pivot and with its lugs 2 ^S comes out of engagement with the lugs 2 ^{4 of} the lever 2 ^2. The lever 2 ² , which carries a weight 2 ⁵ , now falls down on its pivot and changes the weight distribution on the right arm of the balance beam such that the balance pan 3 becomes overweight and moves downwards for complete emptying. It is advisable ^{to choose the weight 2 5} such that on the one hand, when it falls down, the weighing pan is lowered accordingly, and on the other hand, after it has dropped onto the column 16, the weighing pan is prevented from swinging up until it is completely emptied is.

Once this is done, the weighing pan 3 rises rapidly as a result of the pressure acting on the right lever arm of the balance beam, whereby the weight 2 ⁵ with the lever 2 ² is raised violently by its pin, so that the approach 2 ⁱ of the lever 2 ² comes back into engagement with the extension 2 ^{3 of} the lever 2 ¹ , ie the initial position of the balance is automatically restored.

With this balance, the lever used to reduce the weight effect can be used also form a coherent piece with the weighing weight, which when it is triggered in the equilibrium position the weight arm of the balance beam is reduced by shifting the center of gravity and thereby causes an overweight on the load arm.

Claims (2)

Ρλτεντ-Αν SPRüciiK:
ι. Automatic scales for piece goods and bulk goods, including liquids, in which the entire weighing weight rests on the balance beam and, after the corresponding goods have fallen in, the weighing pan becomes overweight for further downward movement for automatic emptying by relocating the balance beam center of gravity, characterized in that the center of gravity of the balance beam weight changing lever hangs up on a supporting point, thereby forming a two-armed lever, the weight arm raises the weight arm of the balance beam, at the same time a to- complete emptying of the load container is ensured by the fact that the falling weighing weight puts the triggered weight lever in its initial load
withdraws. 2. Automatic weighing machine according to claim i, characterized in that the The weight lever, which changes the center of gravity of the balance beam, forms a coherent piece with the weighing weight forms, which when triggered in the equilibrium position the weight arm of the balance beam by moving the Reduced center of gravity and thereby brings out an excess weight on the load arm. 1 sheet of drawings.
