Definitions
- the invention relates to a ball throwing device
- the invention is based on the situation that balls are thrown into the ball throwing device in an uncontrolled manner
- the object of the invention is to ensure that the device automatically adapts to the respective diameter of the balls. It must therefore not be blocked by large balls or small balls
- a roller is mounted on a pivoting lever which can be pivoted against the force of a spring and whose pivoting axis, which runs parallel to the axes of the rollers, is mounted on the pivotable carrier.
- FIG. 1 shows a schematic illustration of an exemplary embodiment from the side
- FIG. 2 shows the corresponding top view when the rollers are pressed apart
- FIG. 3 shows an enlarged side view of parts essential to the invention, likewise with rollers pressed apart.
- the device shown in Fig. 1 and 2 each consists of a base frame, of which only the
- Support column 14 is executed in more detail.
- a support 10 which can be pivoted about the axis 4 attached, which in turn carries a pivot axis 9 for a pivot lever 7.
- Rollers 5 and 6 with the usual design for ball throwing devices are mounted on the one hand on an axis 3 carried by the swivel lever 7 and on the other hand coaxially to the carrier 10.
- the pivoting of the carrier 10 takes place in that a pressure is exerted on the web 16 connected to the carrier 10 via a handle 20 and a stop which can thereby be screwed in and out. If the balls 1 are fed into the space between the rollers 5 and 6, as in the illustrated case, by rolling along a sheet metal bracket 2, it is expedient to connect this sheet metal bracket to the web 16 so that it is also when the carrier 10 is pivoted Location relative to roles 5 and 6 does not change.
- the core of the ball throwing device described so far is surrounded by a housing 15, the upper side of which has a filling opening for the balls 1.
- the filling opening 22 is followed by a storage container (not shown) for the balls, which preferably has the shape of a wire helix through which the balls push each other downwards.
- this has a support pin 21, to which a support bracket 23 is flanged. There is a locking pin 19 mounted, which can be withdrawn from the path of the balls 1 by an electromagnet 18 against the action of a spring 17. This ensures that the balls 1 in desired time interval individually through the sheet metal bracket 2 in the ejection area between the rollers 5 and 6.
- a motor 12 which is arranged coaxially to the roller 6, is used to drive the rollers 5 and 6. Care must be taken to ensure that there is no rigid coupling between the motor shaft and axis 4 in order to protect the motor bearings.
- the roller 5 is driven in that the rollers 5 and 6 touch along their circumference, a friction lining 13 making it easier to take the roller 5 with them.
- the spring 8 which not only presses the roller 5 frictionally against the roller 6, but above all serves to allow larger balls to pass between the rollers 5 and 6 and to eject them properly. If a larger ball gets between the rollers 5 and 6, the device reaches the position shown in FIGS. 2 and 3, in which the axes 3 and 4 are pressed apart against the resistance of the spring 8. The circumference of the rollers 5 and 6 come out of engagement, but it is irrelevant that in this situation the ball passing between the rollers 5 and 6 takes over the power transmission.
