Description

The invention relates to devices for the distribution of pins in a bowling alley.

A device for distribution of pins in a bowling alley is known, which contains a conveyor arranged above the receiving pockets made in the form of endless parallel cables arranged along which the strips are pivotally mounted to guide the pins into the pockets and the retainer of each strip.

The disadvantage of it is low productivity, since the maintenance of the receiving pockets is carried out by one conveyor, installed with the possibility of rotation.

The purpose of the invention is to improve performance.

This is achieved by the fact that the conveyor has a zigzag shape in the horizontal plane, part of the branches of which is located along the receiving pockets, and the latch of each bar contains a double-arm lever placed at the bottom of the pocket with the possibility of rotation from the weight of the pins, and a rotary stopper having projections for interacting with double arm with lever and bar and connected to the bar by means of a spring.

FIG. i shows the device, top view; in fig. 2 is a section along A-A in FIG. I (with empty pocket); in fig. 3 -

the same, view along arrow B in FIG. 2; in fig. 4 shows a section along B - B in FIG. one; in fig. 5 is a cross section along L-D in FIG. one; in fig. 6 is a section along d-d in FIG. one.

The device comprises a frame 1, a conveyor 2 mounted on it, having a zigzag shape in the horizontal plane, branches 3, 4 and 5 of which are located along the receiving cages 6. The conveyor is made in the form of endless parallel cables 7, covering

the rollers 8 mounted on the drive shaft 9. The branches 10 and 11 of the conveyor are with branches 3, 4 and 5 an angle of about 25 °.

Claims (1)

Slats 12 are hinged along the conveyor between its cables to guide the pins into the pockets. The latch of each strap consists of a two-armed lever 13 placed at the bottom of the pocket 6 (see Fig. 2) with the possibility of rotation relative to the axis 14 under the action of the weight of the pins 15 in the pocket, and turning Hoio cT () iio) a 16 (see Fig. 3), having exponents 17, 18 and 19 for interacting with n, an () G | 12 and its support 20. Stopper 16 St.: En with the strap 12 through the spring-21. The slats 12 have bevels 22 for relief on iipaii .icHHJi keg.yu in the pockets. In addition, (the two-armed lever arm 23 is mounted on the frame with the possibility of rotation in the direction of crpe; iKH In iodine with the action of the hierocH of the stop 24 of the movable frame of the bowling alley iodine {not shown in the drawing). The device works as follows. After a perfect throw by the ball, the drop of the pins is lifted by the vertical conveyor, oriented in one direction and fed to the device for distributing the pins across the pockets, i.e. falling onto the conveyor 2 of the device and moving it. The slats 12 located between the cables 7 of the conveyor can take one of two positions: active, in which the pins are sent to empty pockets, and passive, with occupied pockets. With the active position of the slats, when the pockets 6 of the jaws and two shoulders, the levers 13 occupy the position shown in FIG. 2, the shoulder 25 of this lever is located above the protrusion 17 of the rotary stopper 16, and the protrusion protrusion 18 is located under the stop 20 of the bar (see Fig. 3). The bar in this case is fixed in the raised position. A pin 15 passing along the conveyor bumps into the raised bar 12 and, thanks to the bevel 22, guides it into an empty pocket 6 (arrow G in FIG. 2). When the pins are in the man's pocket, the two shoulders lever 13 rotates under the action of the weight of the pins relative to the axis AND in the direction of the arrow And, the shoulder 25 releases the protrusion 17 of the stopper 16, and the protrusion 18 comes out from the stop 20 of the bar and records the position shown on FIG. 3. In this float, the strap 12 can rotate freely about the axis 26 in opposition to the weak spring 21. Passing the pins along the conveyor, hitting the bar, loads it in the plane of the conveyor (arrow K) under the action of its weight and remains on cables 7 conveyor. The double-shouldered lever 13 can be rotated in the direction of the arrow I under the action of the weight of the pins almost to the vertical position in order to release the pins from the pocket into its balance weight (not shown). In this case, the lever 13, when rotated, interacts with its protrusion 27 with the surface 28 of the latch 23. When the frame of the bowling alley is raised, the latch rotates around the axis 29 in the direction of the arrow E, and the protrusion 27 of the two arms is released. During this process, the bar 12 is held in its passive position, i.e. in the conveyor plane by hooking the projection 19 of the stopper 16 to the stop 20. After dropping the pins from the pocket of the two shoulders lever 13, the spring returns to its original position and the next the pin can be re-directed to an empty pocket. Sorted in such a way, the royal pin falls on the branch 30 of the conveyor (see Fig. 1) using the fixed plate 31 enters its corresponding receiving pocket, at the bottom of which there are also two shoulders lever 13 and its latch 23. Thus, transported pins, passage by empty pockets, they are guided into them by means of slats, and in the event of pockets being occupied, they are moved further by the conveyor and dumped at its end into the receiving bar for the pins. Whence the vertical conveyor is picked up again and the process is repeated. Claims An apparatus for distributing pins in a bowling alley, comprising a conveyor arranged above the receiving pockets made in the form of endless parallel cables, along which bars are articulated to guide the pins into pockets, and a clamp of each bar, characterized in that, in order to increase productivity, the conveyor has a zigzag shape in the horizontal plane, part of the branches of which is located along the receiving pockets, and the latch of each bar contains a double-shouldered lever g disposed in the bottom of the pocket pivotally on the weight of the pins and the rotary stopper protrusions for i.meyuschy .modeystvi interac with a two-armed lever and a rod and associated with the strap by a spring.
