Method for operating an electrically operated portable riveting machine, and electrically operated portable riveting machine

1. A method for operating an electrically-operated portable riveting machine, the method comprising:

providing an electrically-operated portable riveting machine comprising:

a housing,

a rivet setting mechanism arranged in the housing, the rivet setting mechanism being configured to set rivet elements into workpieces to be connected,

a collecting vessel,

a delivery duct configured so that spent rivet mandrels created during a setting of the rivet elements are delivered into the collecting vessel,

an actuation switch,

a spent rivet mandrel determination device configured to determine a number of the spent rivet mandrels in the collecting vessel, the spent rivet mandrel determination device comprising an electronic counting device which is configured to count a number of actuations of the electrically-operated portable riveting machine by the user via the activation switch so as to determine the number of the spent rivet mandrels delivered into the collecting vessel therefrom, and

a user information device configured to inform a user when it is necessary to empty the collecting vessel; and

informing the user when it is necessary to empty the collecting vessel.

2. The method as recited in claim 1 , wherein,

the spent rivet mandrel determination device further comprises a sensing counting device configured to count the number of the spent rivet mandrels delivered into the collecting vessel and to form a sum of the spent rivet mandrels, and

based on the sum formed by the sensing counting device, informing the user via the user information device whether the collecting vessel requires emptying.

3. The method as recited in claim 1 , wherein,

the electrically-operated portable riveting machine further comprises a removal sensor which is configured to detect a removal of the collecting vessel from the housing, and

the method further comprises:

zeroing a count of the spent rivet mandrels in the collecting vessel following a removal of the collecting vessel from the housing.

4. The method as recited in claim 3 , wherein the user information device comprises a display which is configured to at least one of,

display to the user whether and/or when it is necessary to empty the collecting vessel, and

display to the user a remaining number of riveting operations before it is necessary to empty the collecting vessel.

5. The method as recited in claim 3 , wherein the electrically-operated portable riveting machine is configured to communicate with a cell phone via a wireless connection so that information comprising at least one of a remaining number of riveting operations and a need to empty the collecting vessel is transmitted to the cell phone by the electrically-operated portable riveting machine and is displayed to the user on the cell phone via an app.

6. An electrically-operated portable riveting machine comprising:

a housing;

a rivet setting mechanism arranged in the housing, the rivet setting mechanism being configured to set rivet elements into workpieces to be connected;

a collecting vessel;

a delivery duct configured so that spent rivet mandrels created during a setting of the rivet elements are delivered into the collecting vessel;

an actuation switch;

a spent rivet mandrel determination device configured to determine a number of the spent rivet mandrels in the collecting vessel, the spent rivet mandrel determination device comprising an electronic counting device which is configured to count a number of actuations of the electrically-operated portable riveting machine by the user via the activation switch so as to determine the number of the spent rivet mandrels delivered into the collecting vessel therefrom; and

a user information device configured to inform a user when it is necessary to empty the collecting vessel.

7. The electrically-operated portable riveting machine as recited in claim 6 , wherein the spent rivet mandrel determination device further comprises a sensing counting device which is configured to count a number of the spent rivet mandrels delivered into the collecting vessel.

8. The electrically-operated portable riveting machine as recited in claim 6 , further comprising a removal sensor configured to detect a removal of the collecting vessel from the housing of the riveting machine.

9. The electrically-operated portable riveting machine as recited claim 6 , wherein the user information device comprises a display configured to display a remaining number of riveting operations until it is necessary to empty the collecting vessel.

10. The electrically-operated portable riveting machine as recited in claim 6 , wherein the user information device comprises a signaling device configured to emit at least one of an optical signal, an acoustic signal and a haptic signal via which the user of the riveting machine is informed to empty the collecting vessel.

11. The electrically-operated portable riveting machine as recited in claim 6 , further comprising a control unit configured to disable the electrically-operated portable riveting machine when it is necessary to empty the collecting vessel.

12. The electrically-operated portable riveting machine as recited in claim 6 , wherein the user information device comprises a manual actuating device via which the collecting vessel is removed, the manual actuating device being configured to at least one of light up or flash when it is necessary to empty the collecting vessel.

13. The electrically-operated portable riveting machine as recited claim 6 , further comprising a rechargeable battery, wherein the electrically-operated portable riveting machine is configured to provide an autonomous operation via the rechargeable battery.
