DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

(5) With reference to FIG. 1, a machine for setting up bowling pins in predetermined positions comprises a basic structure comprising the following features: a distributing arm 1 which is movable and suitable for releasing the pins one by one each at predetermined positions; a primary system 2 for positioning the distributing arm with respect to the predetermined positions; a lifting wheel 3 intended to deliver the pins to the distributing arm; motor means 4 envisaged to move the distributing arm, along with the primary positioning system and the lifting wheel.

(6) Such a machine may further include a system for conveying knocked-down pins to the lifting wheel. In this instance, this conveying system consists, according to the embodiment illustrated by FIG. 2, of a conveyor belt 6 which conveys the pins to the base of the lifting wheel which integrates means known per se to convey the pins from the central belt up to the distributing arm whereon they are delivered one by one.

(7) As featured in FIG. 1, the distributing arm comprises two elements extending from one another, i.e.: a first conveyer element 12, in the form of an endless belt and extending from the lifting wheel 3; an end element 11, pivotally mounted at the end of the first conveyor element, so as to tilt downwards under the weight of a pin and to unload same in the predetermined position corresponding to the position of the distributing arm (elastic return means tending to return the end element to the high position in the absence of pins on the end element.

(8) Furthermore, the distributing arm, via the first conveyor element, is pivotally mounted about a vertical axis suitable for orienting the distributing arm with respect to the lane width, the distributing arm being further movably mounted in translation along the longitudinal axis of the lane. As such, the combination of the movements of orientation of the distributing arm and translation along the longitudinal axis of the lane enables the distributing arm to unload the pins in all the predetermined arrangements on the target zone of the lane.

(9) In order to move the distributing arm in correspondence with the various predetermined positions, the machine integrates a primary system 2 for positioning the distributing arm.

(10) This primary system comprises: a wheel 10 having a track 100 defining the operating cycle moving the distributing arm. This track 100 has a succession of sections 101 each suitable for conveying the distributing arm into one of the predetermined positions.

(11) For this, the wheel has a track 100 on each of the faces thereof, each of the tracks being connected to the end of a slave lever 102. One end 1020 of each slave lever is connected to the corresponding track and is moved as the feed of the sections progresses. The other end 1021 of the slave levers 102 is connected to the distributing arm such that the combined movements of the slave levers 102 during the rotation of the wheel 10 cause the distributing arm to the moved according to the opening cycle involving a fixed sequence (due to the rotations of the wheel 10, and, consequently, the feed according to a constant sequence of the sections 101 of the track).

(12) It is noted that the rotation of the wheel 10 is obtained via disengaging means between the motor means and the wheel 10. These disengaging means comprise a driving wheel 5220 movably mounted between a position engaged with the wheel 10 wherein it rotates the wheel 10, and a position separated from the wheel 10 wherein the latter remains static.

(13) A control system actuates a to-and-fro movement of the driving wheel 5220 with respect to the wheel 10, via a tilting lever.

(14) According to the machines according to the prior art, this lever is connected to the end element of the distributing arm, such that the tilting downwards of the end element induces the tilting of the lever of the system for controlling the driving wheel tending to bring same in contact with the wheel 10 and rotate the latter.

(15) As such, upon each tilting of the end element of the distributing arm, the driving wheel rotates the wheel 10 and the tracks borne thereby along an angular portion corresponding to one of the sections of the tracks, the duration of engagement of the driving wheel with the wheel 10 being calibrated by the duration of the tilted position of the end element of the distributing arm, noting that, once the pin has left the end element, the latter is returned to the high position by elastic return means.

(16) The assembly described above, with the various constituent parts thereof, corresponds to the existing machines known in the art, but also constitutes the basic assembly of a machine for setting up bowling pins according to the invention.

(17) As such, according to the principle of the invention, the machine further comprises a secondary system 5 intended to interfere with the primary positioning system as described above, this secondary system comprising: control means 51, 52 of the rotation of the lifting wheel, these control means being intended to stop the rotation of the lifting wheel 10 after each pin delivered to the distributing arm; selection means 53, devised to enable a user to define a chosen position, i.e. define a position chosen from the predetermined positions with a view to the set-up, by the machine, of a pin in the chosen position; an automatic control system 540 acting as means for activating/shutting down the primary system and authorising the operating cycle of the primary system until the chosen position has been reached, i.e. until the distributing arm is conveyed in correspondence with the position chosen from the predetermined positions.

(18) The selection means 53 may be described according to various alternative embodiments that can be envisaged, of which: they are integrated in an interface of a software application executed by a tablet, or a smartphone or a computer; they are accessible via an interface of software executed by a terminal comprising for example a touch screen, present at the end of lane at the level of the release zone.

(19) The secondary system uses, according to the present embodiment, a support frame 50 intended to support some constituent elements of the secondary system.

(20) This support frame is rigidly connected to the distributing arm, at the side whereof as illustrated by FIGS. 2 and 3.

(21) With reference to FIGS. 2 and 3, the means for controlling the rotation of the lifting wheel comprise: a presence sensor 51, borne by the support frame at a distance from the lifting wheel (approximately the length of a pin in the reclined position or the height when it is upright), this sensor being intended to detect a pin conveyed by the distributing arm when it passes in front of the sensor, the latter then emitting an electrical signal; disengaging means 52, between the motor means 4 and the lifting wheel 3, these disengaging means being controlled by the presence sensor.

(22) According to one preferential embodiment, the disengaging means 52 consist of an electromagnetic pulley actuated by motor means, and conveyed to the disengaged position under the instruction of the electrical signal emitted by the presence sensor of a pin on the distributing arm if applicable.

(23) In the absence of this signal, the electromagnetic pulley rotates by default, the rotation of the pulley being resumed after having unloaded the pin in the chosen position and after having positioned the distributing arm in a new chosen position to be reached.

(24) As described above, the primary system of the machines according to the invention comprises a wheel having a track 100 defining an operating cycle moving the distributing arm, the track having a succession of sections 101.

(25) According to the present embodiment of the invention, the means for activating/shutting down the primary system comprise: at least one marker 520 for a zero position of the distributing arm (this position being the reference position for starting an operating cycle); means for reading 521 the marker; means for controlling 522 the rotation of the wheel suitable for making a computation of the number of sections to be fed (by successive fractions of rotation of the wheel, each fraction corresponding to the angular stroke whereon a section extends) to reach the chosen position from the marker.

(26) Preferentially, the means for reading the marker consist of at least one inductive sensor, suitable for detecting the marker of the zero position, and for emitting a signal transmitted to an automatic control system 540 (including control means 522) of the machine which, prior to an operating cycle, rotates the wheel until the marker is conveyed opposite the inductive sensor. The distributing arm is then in the zero position. The control means compute the number of sections to be fed from the zero position in order to rotate the wheel according to this computation and, consequently, position the distributing arm in the chosen position.

(27) Furthermore, it is noted that the means for controlling the rotation of the wheel comprise primary disengaging means in the form of a driving wheel 5220 as described above, carrying out the transmission between the motor means 4 and the wheel 10, with a control lever 5221 of this driving wheel.

(28) In this context, the secondary system comprises an actuation system 54 of the control lever, via the automatic control system 540 of the machine, envisaged to actuate the lever with successive pulses according to the computation made by the control means: the number of pulses is equal to the number of sections to be fed from the zero position.

(29) As illustrated by FIGS. 2 and 3, the actuation system 54 of the control lever comprises a cylinder wherein the piston is coupled with the control lever, the cylinder being borne by the support frame of the secondary system, and being controlled by the automatic control system in order to press on the control lever as many times as required in order to rotate the wheel and, consequently, feeding the sections until the section corresponding to the chosen position has been reached.

(30) A typical operation of a machine for setting up bowling pins according to the invention may be performed as follows: after a ball throw performed by the player, the automatic control system of the machine actuates the removal of the pins from the lane, which results in all the pins being conveyed to the conveyor belt, the lifting wheel being stopped; the player chooses the configuration of pins that he/she wishes to play, via the selection means of the machine; according to the chosen position, the distributing arm is positioned; the lifting wheel actuates a pin present on the conveyor belt and actuates same until it is released on the distributing arm; when the pin passes in front of the presence sensor of the distributing arm, the lifting wheel is stopped.

(31) Optionally, if the player has selected a plurality of pins to be positioned, this cycle is repeated for the new position.

(32) An exemplary embodiment of the invention proposed a solution particularly meeting the requirement described above in the Background section.

(33) Although the present disclosure has been described with reference to one or more examples, workers skilled in the art will recognize that changes may be made in form and detail without departing from the scope of the disclosure and/or the appended claims.
