DE1098222B - Pressure or display device for inclination scales with a weighing range that can be expanded by adding weights - Google Patents

Description

The invention relates to a printing or display device for inclination scales with additional weights expandable weighing range, in which the value of the additional weight by means of an in the transmission path between the scanning device for the inclination pendulum and the feature carrier with the through the additional weight determined by the type wheel switched on the weight values of the basic weighing range is added in such a way that the summation of the weight values when adding an additional weight prepared and carried out when scanning the deflection angle of the inclination pendulum. In known devices of this type, a wedge, a lever or an addition mechanism is used Helical gear. These gears are made up of parts that can only be produced individually with the required precision can be produced, put together, require a relatively large amount of space and therefore complicate the Construction of the registration device considerable.

In contrast, the invention aims at an improvement through a clearly arranged and space-saving Construction in which stamped parts can essentially be used.

The printing or display device according to the invention is characterized in that one with the Snap-in weights assigned locking steps provided and via a ring gear with a drive wheel for the feature carrier in engagement, disk-like Gear element together with a transmission lever, which has one on a bearing pin at one end movable, in the area of the locking steps of the gear element reaching ratchet lever carries and at its other end it is linked to a button for the higher decimal point via links is and with a setting of the ratchet lever in the corresponding to the additional weight attached Position controlling control disc is arranged on a common shaft and that this is the Control disk is pivotable by means of a lever that a pawl of the pawl lever by the Rotation of the gear element in the area assigned to the additional weight that is switched on Rest step reached.

In the case of the new registration device, one effects both on the transmission element and on the housing Registration device attached spring, which when returning the gear element in the starting position is tensioned by means of a cam disk, the actual adding or recording process.

The invention is explained on the basis of the drawings using an exemplary embodiment. Here are the drawings executed schematically.

The measuring force is transferred from the load carrier of the scales via tension band 1 and curve 2 to the inclination pressure or display device

pendulum 3, which deflects according to the load.

During the registration process, the inclination pendulum is in. the insertion position and the deflection angle of the pendulum scanned. For this purpose, the pliers 4 and the Cam 6 mounted on shaft 5 actuated. the The cam works with the gear element 8 resting on the shaft 7 and is there for free the registration process. By means of the cam, the gear element is activated at the end of the registration returned to the starting position and the mainspring 9, which between the gear element and the Housing of the registration device is attached, stretched. During the registration process, the gear element pivoted to the right by the mainspring. The ratchet lever 10, which is shown in the illustrated Embodiment for the normal weighing range with its pawl 11 in the effective range of the Locking step 12 'of the gear element is located, detected by the locking step 12' and together with the transmission lever 13, on which the ratchet lever is articulated by means of the bolt 14, is pivoted about the shaft 7. This movement takes place until the button 15, via the coupling 16 and the lever mounted on the shaft 17 18 and the coupling 19 is connected to the transmission lever 13, rests on the inclination pendulum. Through this the deflection angle of the inclination pendulum is converted into a rotation value and transferred to the feature carrier 20, the drive wheel 21 of which engages on the shaft 22 with the ring gear 23 of the gear element stands, transferred. For the extended weighing range, the additional weight value must match that taken from the inclination pendulum and transferred to the feature carrier Value to be added. For this purpose,

means of the lever 24, the control disk 25 is pivoted such that the ratchet wedge of the ratchet lever which the spring 26 holds on the control edge of the disc 25, in the area of the respectively attached connecting weight corresponding key stage 12 arrives. If the weighing range is extended, the gear element transmits 8 then in a first rotary movement until the corresponding to the added weight Latching step on the ratchet lever rests the switch-on weight value on the feature carrier and adds in one second rotary movement until 'the button 15 rests on the inclination pendulum, the weight value of the goods to be weighed added. At the end of the registration process, the spring 27 sets the gear parts 15 coupled to one another, 16, 18, 19, 13, 10 against the stop 28 fixed to the housing. The position of the feature carrier 20 is over the button 29 is transferred to the type wheel 30 and by means of the print hammer 31 on a recording medium registered.

Claims (2)

PATENT CLAIMS: 1. Pressure or display device for inclination scales with expandable weights Weighing range in which the value of the additional weight is measured by means of an in the transmission path between the scanning device for the inclination pendulum and the feature carrier the type wheel switched on, determined by the additional weight, the weight values of the basic weighing range is added in such a way that the total of the weight values prepared when placing the additional weight and carried out when scanning the inclination pendulum is, characterized in that a latching steps associated with the switch-on weights (12, 12 ') provided and over a ring gear (23) -with a drive wheel (21) for the feature carrier (20) in engagement, disk-like Gear element (8) together with a transmission lever (13) at one end one on a bearing pin (14) movable in the area of the latching steps (12, 12 ') of the gear element (8) carrying the ratchet lever (10) and at its other end via intermediate links (19,18,16) with a button (19) for the higher one Decimal value is coupled and with a setting of the ratchet lever (10) in the each position controlling control disc (25) on a common shaft (7) is arranged, and that the control disc (25) by means of a lever (24) can be pivoted in such a way that a pawl (11) of the pawl lever (10) is caused by the rotation of the gear element (8) in the area of the respectively activated additional weight Locking step (12; 12 ') arrives. 2. Printing device according to claim 1, characterized in that one on both the gear element (8) as well as on the housing of the registration device attached spring (9), which when returning of the gear element in the starting position by means of a cam disk (6) is actuated the actual adding or registering process.
