Description

Devices are known for launching paper rolls from one floor to another with their simultaneous rotation by 90 using a swinging frame with a counterweight.

The peculiarity of the described device is that in the upper part of the pivoting frame there is a platform with rollers, one end of which is joined to the drive roller table, which feeds the rolls to the platform, and the other end is equipped with a perpendicular resistant. Locally located platform. The latter is separated from the blade of the axis of rotation of the frame at such a distance that the center of gravity of the filed on the roll platform creates a torque. necessary for lowering and turning the platform with a roll. In such a device, the roll is lowered and rotated by 90 ° under its own weight without being applied to a third-party energy source. For a smooth descent and rotation of the roll on the axis of rotation, the rocker arm is firmly planted, the ends of which are pivotally connected to the rods of hydrocyl; Ndrov. In addition, to control the rotation of the frame on the floor near the drain device, a spring-loaded pedal is pivotally attached, which is connected to the two distribution valves and interlocking with the wheels of the self-propelled loader.

In the drawing, the described device is schematically depicted.

Ra.ma / device is rigidly fixed on the shaft 2, bearings

which are mounted on racks 4. On the upper part of the frame is ukreilen platform 5 e rollers 6. One end of the platform 5 joins

with a drive roller conveyor 7 with the help of lock 8, and at the second end of the nej there is a fixed platform 9 installed on the platform. At the bottom number 156470

The counterweight 10 is located on the frame part thereof. with reverse valves 18 and 19. For controlling the spools, there is a pedal 20 which is rotated relative to the hinge 21 n and held in the upper position by the spring 22.

The paper roll 23 is freely fed over the drive roller table 7 to the platform 5 up to the supporting pad 9, since the stop of the lock 8 is recessed. Due to the fact that the length of the platform is asymmetrical to the vertical axis of the frame /, the paper roll alternates the center of gravity of the rotatable part of the device over the shaft 2, and the pressure in the hydraulic cylinder 15 rises.

The electric lift truck 24, when approaching the device, pushes the pedal 20 with the front wheel 25 and opens the spools 16 and 17. The oil from the cylinder 15 under the pressure of the roll through the spools and the check valve 19 is poured into the cylinder 14, the frame is rotated 90 ° and the roll is moved to the platform 9. Thereafter, the roll is clamped by the side locks 26 and lifted.

After the roll is removed, the center of gravity of the rotary frame under the action of the counterweight moves to the other side of the shaft 2. At the same time, pressure is created in the cylinder 14, since the oil outlet from it is blocked by the shutter 17 and the check valve 19.

When the loader departs from the device, the pedal under the action of the spring 22 rises and the spools 17 and 16 open. The oil passes through the spool 17, the check valve 18 n spool 16 passes from cylinder 14 to cylinder 15, and the frame returns to the vertical position under the action of the counterweight.

When the platform 5 interacts with the lock 8, its support 27 is sunk and releases the passage to the rolls on the platform. While the frame is turned, the stop 28 of the lock 8 is raised and keeps the rolls from falling.

Zamok 8 interlocked with the limit switch drive roller 7.

The described device can overload the rolls one by one or several pieces at once, depending on their sizes.

Subject invention

Claims (3)

1. A device for lowering the rolls of paper from one floor to another with their simultaneous rotation by 90 °, using a swing frame with a counterweight, so that it is necessary to use its own weight of the roll for descending and turning by 90 ° without using an extraneous energy source, a platform with rollers is fixed on the upper part of the rotary frame, one end of which is joined to the drive roller table that feeds the rolls to the platform, and the other end is provided with a perpendicularly perpendicular platform located on such R ssto apart from the axis of rotation of the plane of the frame to the center of gravity applied to the roll platform created a torque necessary for running and novoroty platform roll. 2. The device according to claim 1, characterized in that, for the purpose of smooth descent and rotation of the roll, a rocker is rigidly planted on the axis of rotation of the frame, the ends of which are pivotally connected to the rods of the two. hydraulic cylinders pivotally mounted on the fixed part of the ram. 3. The device according to PP. 1 and 2. characterized in that, in order to control the rotation of the frame, a spring-loaded pedal is articulated on the floor near the lowering device, connected by means of two distributing valves, bypassing the working fluid from one cylinder to the other when hitting it or coming off her self-propelled loader. 4% - .. 7 / f- --- 19 iS / / / # / 7
