Definitions

  • the invention relates to a device for setting up a number of standing objects, in particular bowling pins, in a determined pattern on a ground, comprising means for supplying the bowling pins, means connected to the supply means for positioning the supplied bowling pins in the determined pattern and means connected to the positioning means for moving the bowling pins to the ground and setting them down thereon.
  • a device is generally known under the designation of bowling pin installation.
  • This set-up device is intended to dispose the bowling pins prior to a delivery in the correct pattern at the far end of a bowling lane and, once a bowling ball has been delivered, to clear away the fallen pins and to replace the remaining pins in the correct pattern for a second delivery. After this second delivery all pins are cleared away and a new set of pins is arranged, whereafter the lane is ready for a new delivery.
  • the known bowling pin installation has an elevator wheel rotatable on a horizontal shaft which delivers the pins to a positioning mechanism.
  • This positioning mechanism consists of a receiving member formed by a framework of rods which together define receiving compartments for the pins and a conveyor which carries the pins to the receiving compartments .
  • This conveyor is controlled by means of a curve disc which ensures that the conveyor is carried along all compartments in a predetermined sequence.
  • the compartments are closed on their underside by displaceable bars which can be moved to a position in which they leave clear the underside of the compartments, so that the pins can drop therefrom.
  • the pins are then collected in lying set-up elements which are then released from the pins and retracted.
  • the above described set-up device or bowling pin installation is therefore a substantially mechanically operating and controlled machine, the original design of which dates from several decades ago.
  • the known bowling pin installation is therefore of complicated construction, voluminous, heavy and expensive, while in addition it has relatively few adjustment options and thus has only a small number of functions.
  • the known device is particularly susceptible to breakdown as a consequence of the large number of often relatively heavy moving parts and requires a great deal of maintenance .
  • the invention therefore has for its object to provide an improved bowling pin installation of the above discussed type which is of simpler construction and thus less costly and less likely to require maintenance and which displays an improved functionality.
  • the supply means comprise at least one substantially vertically running belt conveyor.
  • the belt conveyor preferably comprises an endless belt with a number of compartments formed thereon, the dimensions of which correspond with those of a bowling pin. These compartments can herein be formed by flaps which are either slightly flexible and formed integrally with the belt or which can be form-retaining and connected releasably to the belt.
  • the belt conveyor preferably has close to its top side a portion inclining in the direction of the positioning means. When they reach this portion the compartments with the pins will also incline so that the pins simply roll out of them.
  • the invention provides a set-up device of the above described type wherein the positioning means comprise a receiving member with a number of openings and at least one conveyor displaceable relative to the openings, wherein the form and dimensions of each of the openings correspond with those of a bowling pin.
  • the conveyor can herein be pivoted parallel to the plane of the receiving member and is connected drivably to controllable pivoting means.
  • the conveyor is preferably extensible and connected drivably to controllable extending means .
  • the conveyor can thus be pivoted to any desired angular position and extended to any desired length, and thus be displaced herewith to any desired receiving opening.
  • the bowling pins can thus be disposed in a pattern to be entered by a player, whereby particular situations can for instance be practised or other game options played.
  • the functionality of the bowling pin installation hereby increases considerably.
  • a setup device of the above described type is provided with means arranged under the openings in the receiving member for supporting bowling pins located therein, which supporting means are displaceable between a position at least partially closing the opening and a position leaving the opening completely clear.
  • the supporting means are herein formed by a member which is slidable relative to the receiving member and has a number of releasing openings corresponding with the number of receiving openings, wherein the supporting member, just as the receiving member, can take the form of a plate.
  • the known set-up device is further always provided with means displaceable in vertical direction for picking up the still standing pins from the ground and re-placing them once the fallen pins have been removed, which pickup and re-placing means comprise a number, corresponding with the number of pins, of sets of fingers movable relative to each other by means of a drive.
  • the pins which remain standing after the first delivery can be picked up herewith, whereafter the fallen pins are swept from the set-up surface.
  • the picked-up pins are subsequently re-placed, whereafter the lane is ready for the second delivery.
  • the known fingers are moved toward each other by means of electric motors until a contact arranged in the fingers is closed, which designates the closed position of the fingers.
  • the sets of fingers are then moved upward so that the set-up surface can be swept. Finally, the fingers are carried downward and opened, whereby the pins are once again released.
  • This known mechanism has the drawback that the electrical drive of the fingers and the electrical detection of their closed position requires a large amount of cabling. Because the sets of fingers are further displaceable in vertical direction this cabling will be bent frequently, whereby breaking of the cable occurs after a period of time, thus resulting in breakdowns.
  • the invention thus provides a set-up device wherein the drive is a pneumatic drive.
  • the drive is a pneumatic drive.
  • the need for cables becomes wholly superfluous .
  • means are preferably provided for detecting the position of the set of fingers.
  • the fingers can hereby be prevented from being moved downward while they are in their closed position, since the frame in which the fingers are accommodated could hereby become jammed on bowling pins still standing uprigh .
  • the detection means can take the form of a single sensor.
  • the known bowling installation is generally also provided with means for returning the bowling ball from the position of the pins.
  • These return means herein usually take the form of a lift, with which the ball is carried upward a determined distance, and an inclining gutter connecting onto the lift through which the ball then rolls back under the influence of gravity to a collection point at the beginning of the lane.
  • This construction is also comparatively complex, while in addition the force and speed with which the ball is returned is difficult to adjust since these are fixed when the gutter is designed. Changing the return speed at a later stage is therefore only possible with great difficulty and with a large investment.
  • the invention therefore provides a set-up device with an improved return mechanism.
  • the return means comprise at least one push-back member displaceable through a stroke length and a drive mechanism connected thereto.
  • the push-back member can herein comprise a pivotable arm with a foot connected thereto close to its outer end for bringing into contact with the ball, whereby the ball is as it were "kicked" back.
  • this latter is further provided with a blocking member pivotable on a horizontal shaft and with means connected thereto for " damping the pivoting movement.
  • This blocking member also serves to detect the presence of a ball, for which purpose it is connected to a switch or contact which, when the blocking member moves, opens or conversely closes a circuit. Due to the presence of this switch the installation space for the damping means is limited. Use is therefore generally made of a telescopic shock absorber directed at a small angle to the blocking member. The loads on the shock absorber are hereby considerable and the effect thereof limited.
  • a setup device is therefore provided with an improved damping of the blocking member.
  • the damping means are directed horizontally.
  • the direction of the damping is hereby parallel to that of the load, whereby an efficient damping is achieved.
  • the horizontal disposition of the damper (s) is possible because no use is made of switches connected to the blocking member for detection of the ball but an optical sensor detects the passage of the ball instead.
  • the known bowling installation is further generally provided with a conveyor for discharging knocked over pins.
  • This conveyor which extends from the set-up surface for the pins to the elevator wheel, is herein driven synchronously with the elevator wheel . In the case where a large part of the pins are knocked over in one delivery, there is the danger of these pins accumulating at the end of the discharge conveyor, which may result in jamming of the machine.
  • a set-up device is therefore provided wherein this danger does not occur.
  • the discharge conveyor is driven independently.
  • the drive is herein also adjustable. The discharge of the knocked over pins can thus be stopped temporarily when the elevator belt is in danger of becoming blocked.
  • the invention relates to a playing surface, in particular a bowling alley, which is provided with a substantially flat lane which is elongate in top view and at the one end of which is defined a set-up surface for standing objects, in particular bowling pins, and with a set-up device as described above arranged in the proximity of the set-up surface.
  • Fig. 1 shows a partly broken away perspective rear view of a set-up device according to the invention
  • Fig. 2 shows a partly broken away perspective view of the positioning means of this device as according to arrow II in fig. 1, and
  • FIG. 3 is a perspective view of the pick-up and replacing means of the set-up device according to the invention.
  • a device 1 for setting up a number of bowling pins 9 in a determined pattern on a ground 57 (fig. 1) is provided with means 2 for supplying pins 9 , means 3 connected thereto for positioning pins 9 in the pattern, and means 4 for lowering and placing the pins 9 positioned in the desired pattern onto the ground 57.
  • the supply means 2 are herein formed by a substantially vertically directed belt conveyor which consists of an endless belt 6 trained round two reversing rollers 10, 74 and driven by a motor 12, and on which a number of compartments is formed.
  • Upper reversing roller 74 herein has a larger diameter than lower reversing roller 10 and two guide rollers 75 are placed on either side of belt 6 directly beneath upper reversing roller 74. A portion inclining toward the positioning means 3 is hereby formed.
  • the compartments, which have practically the same dimensions as the pins 9 for transporting, are defined by flaps 7 which can be manufactured integrally with belt 6, and are then therefore slightly flexible, or which can be releasably connected to belt 6, in which case flaps 7 can be form-retaining plastic parts.
  • Pins 9 leave the conveyor at the position of the inclining portion at the top through an opening arranged in the housing 13 of the conveyor.
  • the pins fall herefrom into a receiving chute 14 which is provided with a specially formed recess 15 whereby pins 9 are always aligned in the same manner. Pins 9 are thus always passed to positioning mechanism 3 with their belly 35 directed to the front and their neck 36 to the rear.
  • Positioning mechanism 3 has a plate-like receiving member 37 with a number of openings 38, the shape and dimensions of which correspond with those of pins 9.
  • the positioning mechanism further has a conveyor 16 which is displaceable relative to openings 38.
  • Conveyor 16 is a belt conveyor in the shown embodiment with an endless belt 17 transported over two reversing rollers 18, 19. Belt 17 is driven by a motor 77.
  • the conveyor 16 is not only pivotable on an axis 26 as according to arrow P but can also be extended as according to arrow E.
  • intermediate roller 20 For this purpose it comprises two intermediate rollers 20, 21 wherein intermediate roller 20 is accommodated fixedly in a frame 22 relative to reversing roller 18, while intermediate roller 21 is accommodated with reversing roller 19 in a second frame 23 which is slidable relative to fixed frame 22.
  • This latter has a bearing housing 24 having arranged therein a number of bearing rollers 25 between which frame 23 is movable.
  • a pneumatic cylinder 76 Use is made of a pneumatic cylinder 76 to extend the second frame 23.
  • the pivoting movement of the conveyor is driven by a motor 27 which via a right-angled transmission drives an output shaft 72 and a friction roller 28 arranged thereon.
  • Shaft 72 is herein mounted in a carrier 73 connected to frame 22.
  • Carrier 73 further has a second passive tracking roller 36.
  • output shaft 72 is provided with a pattern 29 and a pulse generator 30 U) L t t
  • Positioning mechanism 3 is further provided with means 42 arranged under the openings 38 in receiving member 37 for supporting the pins 9 situated therein.
  • These supporting means 42 are formed in the shown embodiment by a plate-like member 43 having therein a number of releasing openings 44 which correspond in both shape and number with receiving openings 38.
  • Plate-like supporting member 43 is slidable relative to receiving member 37.
  • Supporting member 43 has a first position in which openings 44 are shifted slightly relative to openings 38 in receiving member 37, so that these receiving openings 38 are therefore partially closed and the pins present therein are supported along their periphery.
  • the supporting member is displaceable from this position as according to arrow D to a second position in which openings 38 and 44 in both plates 37 and 43 lie precisely in register with each other and the openings 38 are therefore left completely clear so that the pins 9 situated therein drop downward into the set-up elements or holders 45 to be discussed hereinbelow.
  • Table 47 also supports via legs 90 the means 80 for picking up the still standing pins 9 from the set-up surface 57 and for re-placing thereof after the fallen pins 9 are removed (fig. 3) .
  • These pick-up and re-placing means 80 are formed in per se known manner by a number, corresponding with the number of pins 9, of sets of fingers 81, 82 which are movable in each case relative to each other.
  • These fingers 81, 82 are accommodated rotatably in a frame 83 which has openings 84 for passage of holders 45 and pins 9. Fingers 81, 82 are driven collectively in conventional manner by a system of parallel actuating rods 85 which are connected by a coupling rod 86.
  • Fingers 81, 82 are herein connected to each other and to actuating rods 85 such that from the opened starting position one of the fingers 81 is first moved toward the other finger 82 and then, when resistance is encountered from for instance the neck of pin 9, this finger 81 comes to a stop, whereafter the other finger 82 is moved toward it until the fingers 81, 82 eventually close round the neck 36 of pin 9. If no upright pin 9 protrudes through opening 84, finger 81 moves fully against the other finger 82. In the conventional device a contact is in this case closed, this representing an indication for the absence of a pin 9 in the opening, which therefore has evidently been knocked over. The score is kept in this way.
  • the score is kept in optical manner by means of a camera 88 directed at set-up surface 57.
  • the electrical contacts and associated wiring to the fingers can thus be omitted.
  • the score camera 88 is herein also connected to image processing means, for instance in the form of a computer, with which it is possible on the basis of a special algorithm to derive from the recording made by camera 88 which bowling pins 9 are still standing.
  • the fingers 81, 82 are now driven pneumatically by means of a cylinder 87.
  • the device has means for detecting the position of each of the fingers 81, 82.
  • These position detecting means are formed in the shown embodiment by a single sensor 89 which can detect for instance the position of a marking element 91 on one of the actuating rods 85. Because all fingers 81, 82 are driven collectively, this single detection represents a sufficient indication of the position of all fingers 81, 82.
  • a blocking member or "cushion plank” 92 is arranged with small interspacing above discharge conveyor 8 on the rear side of set-up surface 57.
  • This blocking member 92 which is covered with a layer of absorbing material such as for instance rubber, is suspended from two arms 93 which are connected to a transverse shaft 94 which in turn is pivotally mounted in a number of bearings 95 connected to the frame of the device.
  • a horizontally directed shock absorber 96 is connected to at least one of the arms 93.
  • shock absorber 96 which results in a good damping, is possible because the blocking member in the device according to the invention does not serve as indication that a ball has been delivered.
  • the switch (es) present for this purpose in conventional bowling installations and connected to blocking member 92 is therefore omitted.
  • an optical sensor on the front side of set-up surface 57, for instance in the form of a light source 100 and a light-sensitive cell 101 placed opposite.
  • the distance between blocking member 92 and conveyor 8 is otherwise chosen such that the pins 9, but not the ball 60, can pass beneath the blocking member.
  • a mat Arranged on the top of blocking member 92 is a mat (not shown here) which is connected to the frame of the device and serves to prevent pins 9 bouncing over blocking member 92.
  • the device For sweeping of the fallen pins 9 from the set-up surface 57 to the discharge conveyor the device is provided with a per se known slide or "sweep" 52 which is movable downward after a delivery and which is displaceable as according to arrow SW over set-up surface 57.
  • Slide 52 is suspended from two toothed transport belts 56 which are driven by toothed wheels 54 connected to a motor (not shown) and arranged on a collective drive shaft 53.
  • Discharge conveyor 8 is formed by an endless belt 97 trained round two reversing rollers 98, one of which is driven by a motor 99.
  • the plane of conveyor 8 inclines slightly in transverse direction in order to urge a ball lying against blocking member 92 to a side of the device.
  • a widening channel is moreover formed in a support plate arranged under the transporting part of belt 97, whereby ball 60 is urged even more strongly to the side.
  • Motor 99 is controllable and can be temporarily stopped when a large number of pins 9 are knocked down simultaneously. An accumulation of pins 9 at the end of discharge conveyor 8 is thus prevented when elevator conveyor 6 cannot process the supply of pins 9 quickly enough. The danger of the device jamming is thus minimized.
  • the bowling installation also comprises means 5 for returning the delivered bowling ball 60 from the position of the pins 9. Either as a result of the slope of conveyor 8 or of rolling through one of the gutters 71 arranged on either side of lane 70, each ball 60 finishes up in a transverse gutter 61. This latter is closed by a sliding door 62 which is operated by a pneumatic cylinder 63. One ball 60 at a time is thus fed to the return means 5.
  • These return means 5 are herein formed by a push-back member displaceable through a determined stroke length by a drive mechanism.
  • the push-back member consists of an arm 64 which is pivotable on a shaft 58 as according to arrow R.
  • Pivot arm 64 is provided with a foot 65 which is arranged close to its outer end and which can be placed into contact with the ball .
  • the drive mechanism is further formed by a pneumatic cylinder 66. By extending this cylinder the ball 60 is as it were “kicked back" through a gutter 67 and via an inclining gutter part 68 eventually finishes up in a collecting gutter 69 at the side of the lane 70 where the players are to be found.
  • the set-up device can fulfill considerably more different functions than conventional bowling installations.
  • the device is hereby very suitable for use in combination with advanced control systems.
  • due to the chosen form and operation of the different components a greater speed, better reliability and less susceptibility to maintenance are achieved, while the cost and weight of the device are also greatly reduced.
  • Particularly the large scale use of easily controllable, accurate and light pneumatic drives plays a major role here.
  • a further advantage of the use of pneumatic drives is that tracing and analysis of disturbances is greatly simplified hereby .
