Safety equipment on scales with counter and weight printing device. Patented in the German Empire on November 20, 1920.

The present invention relates to a safety device for scales with counter and card printing device, which consists in the fact that a locking device is only then released when the balance is in equilibrium and a weight print is taken.

There are facilities in which the number of weighings is counted; here will the pull created by the load on the scales is used for counting. The counter every time a load is placed on and removed from the weighing platform switched. The purpose here is to determine the number of loads on the scale.

867865 It is also known for inclination scales to transfer the respective loads to a counter and to add them up. However, these scales usually do not have a security device or card printer. In the drawing, an embodiment of the safety device in connection with a counter and a card printer is shown schematically. ίο The weighing beam α carries in a known manner the running weight b, which is moved by means of a gear c and a rack d connected to the running weight. A disk / is attached to the gearwheel, which is known to ensure that the running weight must always be correctly adjusted to the pressure line. This "disk can be designed in such a way that the incisions, which since then have prevented a subsequent shifting of the barrel weight during the impression, are different in depth and are in proportion to the set weight. The horizontally arranged three-armed slide g is positioned by means of its upper arm g The middle arm g2 engages in the recess of the disk f, while the lower arm g3 is connected on the left side to a weight h, its right end carries a slotted tab I. A crank k which only can be rotated in the direction of the arrow, is connected by a connecting rod to a two-armed lever with which on the one hand the weighing beam α is fixed or released for weighing, and on the other hand the three-armed slide g is moved to the right by means of the slotted tab i holds the three-armed slider in its extreme right position, is carried by a two-armed lever 0, the is actuated by the pressure lever p known on the security card printer. The individual elements can also be replaced by others in a corresponding manner, just as their arrangement can also be changed without changing the essence of the invention. If there are several running weights, the same arrangement can be used for each of the running weights. If the setting of the running weights to the equilibrium position and the print line is done with the security card printer, so that the weighing card can be inserted into the card printer in a known manner and the pressure lever can be pressed down to print the weight, then the lever ρ moves the two-armed lever 0 and pulls the locking bar η upwards. The three-armed slider g is then shifted to the left by the weight h until the arm g2 arrives in one of the recesses in the disk f. The upper arm gx has also moved the same way to the left and set the counter of the load on the balance. A subsequent shift of the barrel weight can no longer be carried out because the slide arm g "prevents the disk / from turning. The slide g must therefore first be moved to the right; this is done using the crank k in the direction of the arrow. When the crank k is turned, the slide g is returned to its initial position and locked in this position by the bolt%. At the same time, the weighing beam α is also locked is, the security card printer and also that of the weighing beam are housed in a lockable housing so that unauthorized interference with the individual movements cannot take place. 1. Safety device on scales with counter and weight printing device, characterized in that the device required for counting, ie the bolt (g), slide o. The like., Is held by a locking mechanism (s) until the locking mechanism is in the equilibrium position the scale is triggered by a weight imprint. . 2. Safety device according to claim i, characterized in that the bolt (g) o. The like. At the same time designed as sensors which engage in partial disks, partial slides or the like. Which serve as a travel limit for the sensor. 3. Safety device according to claim ι and 2, characterized in that that the partial disks, partial slides or the like. Are designed step-like, their steps correspond to the weight divisions of the scales, which then serve as a yardstick for the bolt shift. 4. Safety device according to claim ι to 3, characterized in that the bolt (g) by a winch (k) or the like, with which the balance beam (a) can also be determined at the same time, must be returned to its starting position and locked again before a new weighing can take place. 1 sheet of drawings.
