Abstract

Изобретение позвол ет расширить игровые возможности аппарата. Аппарат имеет несколько метательных головок с подающими роликами 7. Головки на опорах 4 с трем степен ми свободы установлены на раме 1, а последн устанавливаетс на теннисном столе. Под опорами 4 расположен бункер, состо щий из нескольких секций 10 по числу головок. Кажда секци бункера св зана направл ющим каналом с метательной головкой. На выходе из секции и входе в канал установлен кулачок с отсекателем 14. Все кулачки смонтированы на одном приводном валу 15 и могут занимать различное исходное положение с помощью фиксатора 22. Это позвол ет измен ть темп подачи м чей. В каждой секции в направл ющих 21 установлены ворошители 11 м чей. Ворошители кинематически св заны с валом 15. Аппарат позвол ет осуществить установку метательных головок как на одном столе, так и на двух и четырех. Это экономит занимаемую площадь и увеличивает интенсивность зан ти . 2 з.п.ф-лы. 4 ил.The invention allows to expand the gaming capabilities of the apparatus. The apparatus has several throwing heads with feed rollers 7. The heads on supports 4 with three degrees of freedom are mounted on frame 1, and the latter is mounted on a tennis table. Under the supports 4 there is a bunker consisting of several sections 10 according to the number of heads. Each section of the hopper is connected by a guide channel with a throwing head. At the exit from the section and the entrance to the channel, a cam with a cutter 14 is installed. All the cams are mounted on one drive shaft 15 and can occupy a different initial position with the help of a latch 22. This allows changing the feed rate of the pulp. In each section, in the guides 21, the turners 11 are installed. The tedders are kinematically connected to the shaft 15. The apparatus allows the installation of throwing heads on one table, as well as on two and four. This saves space and increases occupancy intensity. 2 hp ff. 4 il.
