Description

Devices are known for separating a stack of paper cups and dispensing them alone using a hopper for loading the stacks, a feeding conveyor and a device for separating the cups one by one by gripping the burnt when the entire stack is retained. A disadvantage of the known devices is the damage to the cups when they are separated from the stack, as well as the separation from the stack but two or more cups.

In the described device, these disadvantages are eliminated.

The peculiarity of the device is that the device for separating cups is made in the form of screw cylinders with parallel axes of synchronous rotation, located symmetrically around the opening for passing the stack, supplied, for example, by means of a grooved conveyor. Screw cylinders are made with viit grooves corresponding to the shape and size of the cuffed cuffs, and are provided with end grooves. The bunker is equipped with a two-bladed flap associated with a system of levers with a hinged probe, which is lowered onto the stack as it advances on the conveyor and acts on the flap as the stack is exhausted.

FIG. 1 shows a diagram of the device; in fig. 2 is a flow chart for separating cups from a stack; in fig. 3 is a view along arrow A (upper part of the figure) and a view along arrow B (lower part of the figure) in FIG. 2, into two screw cylinders — devices for separating cups from a stack; in fig. 4 is a diagram of the drive and blocking two-blade valve.

The main components of the device are: a hopper / with a two-blade flap 2 connected to a probe that acts on the columns; feeding grooved conveyor 3; a damper drive consisting of a cam 4, a spring-loaded lever 5 with a roller 6, ti gi 7; mechanical blocks No. 132532-2 of the flap gate, including a hinged probe 8; a cupping device from the stack, mounted on the base 9, and a bypass tray 10 for the separated cups.

Stacks of cups in a horizontal position are loaded into the bunker U manually, from which (when flap 2 is triggered) the stack is fed to the grooved conveyor 3. When dropped out of the bunker, the stack is fed by conveyor 3 all the way to the remaining previously fed cups, after which the conveyor slips under the stack, since the speed of its movement is greater than the speed of passing the cups through the device for their separation. Between the probe 8, resting on the end of the stack on conveyor 3, and the separator, there is 1 necessary supply of cups supplying the devices until the new stack is fed to the conveyor 3. Gate 2 consists of two rigidly connected plates with an angle of 72 ° between them; in position / (Fig. 4), the flap closes the outlet window of the bunker 1, in the position L opens this window and gives an exit to the stack of cups on the conveyor 3. In the presence of cups under the probe 8, the bar closes the opening in the guide sleeve 11, which moves the rod 12, receiving movement from the cam 4. The rod 12 rests on the probe bar at the very beginning of its movement, and the roller 6 of the lever 5, comes out of contact with the cam 4. In the absence of cups under the probe 8, the latter goes down with the bar that opens the hole in guide to tulku 11. At the same time, under the action of the spring 13, the roller 6 interacts with the cam 4; the lever 5 rotates the flap 2 by means of the cable 7 and the outlet window of the hopper opens. The stack, falling on the conveyor 3, raises the tongue 8 with the bar at the moment when the damper closes under the action of the cam 4.

The cups are separated from the CCTV by means of three simultaneous helical rotating (cylinders) 14, having screw grooves 15 corresponding to the shape and size of the cuffs. When the cylinders 14 are rotated, each cup does not move, the entrance is into the screw grooves with its collar. Thus, the cups are separated from the stack by the cylinders 14 while the rest of the stack is held in place by the recesses located on the front portions of the cylinders. The cylinder 14 is driven as follows: The shaft of one cylinder is the drive shaft, and the other two receive rotation through the central gear 16 and gear wheels / 7, mounted on the shafts of the two cylinders.

Claims (3)

1. A device for separating a stack of paper cups and dispensing them one by one using a hopper for loading the stacks, a feeding conveyor and a device for separating the cups by the collar when the entire stack is retained, in order to separate the cups without damage , the device for the separation is made in the form of screw cylinders with synchronously rotating parallel axes located symmetrically around the opening for the passage of the stack, supplied, for example, by means of a grooved transport ra. 2. The device according to claim 1, characterized in that, in order to grip the end cup over the shoulder and hold the whole stack behind the shoulder of the next cup, the screw cylinders are made with helical grooves corresponding to the shape and size of the shoulder and are provided with end grooves. 3. The form of the device according to paragraphs. 1 and 2, characterized in that, in order to dispense cups onto the conveyor one at a time in a horizontal position as they separate, the bunker is provided with a two-blade valve connected by a system of levers with a hinged probe, which is lowered onto the stack as it moves on the conveyor and on the valve as the stack is used up. / " FIG. 2 View and "Have Fig.Z ig.
