SU123774A1 - Semiautomatic device for selling newspapers and similar sheet products - Google Patents

Description

In the known mechanisms for issuing sheet products in semi-automatic and newspaper-selling machines, the newspaper shelf is lifting, and its uniform lifting is compromised with the help of this more or less complicated mechanism and, moreover, not always guaranteeing an accurate lifting step as newspapers decrease. in the car.

In the proposed semiautomatic device, this disadvantage is eliminated by the fact that the newspaper shelf is fixed and the dispensing mechanism is designed as a pendant with a counterweight and freely sliding along the guides of the frame, a spring-loaded lever interacting with the lever drive, at the end of which a movable carriage fitted with a flexible one is mounted. rubberized foot. In addition, a semiautomatic device uses a convenient device for switching off the coin mechanism in the absence of newspapers, which means that the frame of the dispensing mechanism is equipped with a rod that interacts with a full lowering of the frame with a flap overlapping the coin channel.

FIG. 1 shows a diagram of the main nodes of the semi-automatic; in fig. 2 - a mechanism for issuing newspapers.

A semi-automatic machine for selling newspapers has a coin mechanism of a known type with filters for assessing the quality of coins and with a weight beam. The semiautomatic device operates from a manual lever drive 1. The latter is connected with the arm 2 by a lever 3 of a pivoting lever, the second arm 4 of which is pivotally connected to a spring-loaded lever 5. The frame 7 slides freely along the vertical guide corners 6. One end of the spring-loaded lever 5 is hingedly fixed on the frame, and on the other end of it, a movable kapet 8 is mounted, carrying a flexible rubberized foot 9, which has a curved up and glued over spongy rubber end and its vertical position to a certain extent W is a spring. To the bottom of the ramil 123774- 2 -

Ki 7 is attached by two rollers 11, which directly press a foot G2 of newspapers, which are laid on the sliding shelf 13. At the end of the frame there is also a rod 14 that interacts, when the frame is fully lowered, with the lever 15 of the gate covering the coin channel (not shown in the drawing). The frame is supported by the counterweight 16, which is 250 g lighter than the total weight of the suspended frame, i.e. the frame presses the foot with a constant weight of 250 g

When pressing on the manual drive / spring-loaded lever 5 together with the carriage 8 is retracted, and then under the action of the spring makes a working stroke back. At the same time, the rubberized foot grips the top sheet of the foot 12 and pushes it into the groove P of the release of the goods. The adjustment screw U sets such a degree of pressure of the foot on the foot so that only one sheet is separated. The entire delivery mechanism smoothly descends as the newspapers decrease in a groan, exerting constant pressure on the foot.

Subject invention

1. A semi-automatic machine for selling newspapers and similar sheet products, operating from a manual lever drive and including a coin mechanism using weight rockers and coin filters, as well as hanging pressure rollers in a newspaper dispensing mechanism, characterized in that newspapers, the newspaper shelf is fixed, and the delivery mechanism is designed as a pendant with a counterweight and free speed, but with a vertical guide frame, which interacts with a lever drive A spring-loaded lever, at the end of which a movable carriage is mounted, equipped with a flexible rubberized foot.

2. Semiautomatic device according to claim 1, characterized in that, in order to turn off the coin mechanism in the absence of newspapers, the frame of the dispensing mechanism is provided with a rod that interacts when fully starts the frame with a gate that blocks the coin channel.
