Description

The invention relates to devices for the supply and loading of cylindrical workpieces of technological equipment, such as machines for insulating pipes used for channelless engineering networks in construction.

The purpose of the invention is to increase the reliability of the device.

Fig, 1 schematically shows the device, a general view; NZ: FIG. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 3; in fig. 5 - section., Bb in fig. 3; in fig. 6 — node I in FIG. one.

A device for single-piece feeding of cylindrical products comprises a rack 2 mounted on a base 1 inclined in the direction of delivery of products, formed by guides 3, a piece-by-piece separation mechanism, such as pipes 4, located at its dispensing end and a reloading mechanism.

The piece-wise mechanism includes a shaft 5 horizontally located along the guides 3, on which a fixed stop 6 arranged in mutually perpendicular planes and movable, an abutment 7 for adjusting the mechanism for a certain diameter of pipes, is fixed to the device. branches.

In order to ensure synchronous operation of the mechanisms of piece-by-piece pipe separation, the shafts 5 of each mechanism are connected by means of levers 8 rigidly mounted on shafts 5 with a common thrust 9 movable from the drive 10.

The reloading mechanism includes non-driven biconical rollers 11 whose axles are fixedly mounted on the frame 12 mounted on the base 1 by means of connecting rods 13 with the possibility of raising and lowering in the vertical plane from the drive 14. To create rigidity, the connecting rods 13 opposite one another are connected pairwise diaphragm 15. The raising and lowering of the frame 12 is carried out to align the axis of the pipes with the process equipment, for example, the insulating machine 16, when changing to a different diameter of the pipes. The frame 12 is mounted by means of a horizontal axis 17 located parallel to the longitudinal axis of the rack, a rotary double-arm lever 18. On one of its shoulders is attached a biconical drive roller 19 installed between non-driven rollers II, and in the initial position its working surface is below working surfaces of non-driving rollers 11.

Depending on the length of the pipe in the device there may be several overload mechanisms. For example, in the proposed device there are two. The drive rollers of the mechanisms are interconnected by a chain loop, the rollers 19 are rotated by means of endless chain loops 20 and 21 through an intermediate sprocket 22 with an actuator 23. In addition, the reloading mechanism further comprises a lifting platform for pipes 4, located at the dispensing end of the rack 2, with the placement of its horizontal shelf 25 parallel to the longitudinal axis of the rack. The platform 24 is mounted on the frame 12 so that it can interact with the second arm of the lever 18. A vertical shelf 26 of the platform is mounted in the guides 27. The platform is moved from the drive. The drive can be made in the form of a power cylinder (not shown) or in the form of an electric screw jack containing an electric motor 28, a gearbox 29 and a screw 30.

In the initial position, the frame 12 with non-driven rollers 11 by the actuator 14 for controlling the actuator 10, contains the limit switch 31, the pivoting lever 32, and on the platform 24 is mounted with the lever 32 to interact with the lever 32 bracket 33.

The device works as follows.

In the initial position, the frame 12 with the non-driven rollers 11 of the idler m 14 rises to align the longitudinal axis Of the pipe 4, which lies on the rollers 11, with the axis Ojj of the insulating machine 16 and is fixed in this position. The first stops 6 on the side of the rack end 2 of the rack 6 are arranged vertically, and the stops 7 are horizontal, and the drive control circuit 10 is de-energized.

When the motor 28 is turned on, the platform 24 is raised to its extreme upper position by means of the screw 30, while moving upward the bracket 33 rotates the lever 32, which interacts with the limit switch 31, as a result, the control circuit of the drive 10 closes and rotates the shafts 5 and stops 6 and 7 one pipe is cut off. The trimmed tube rolls down onto platform 24, and stops 6 and 7 occupy their original position. Platform 24 descends and transfers the pipe to the non-driving rollers 11. Continuing its movement, the platform interacts with the lever arm 18, turning it in a vertical plane until the necessary pressing of the driving roller 19 is created against the pipe located on the non-driving rollers 11, the second reload mechanism works synchronously with first. Then, the drive 23 of the rollers 19 is turned on and the pipe 4 is fed to the insulating machine 16, after which the drive is turned off.

The electric motor 28 is turned on, and the platform 24 is moved upward, freeing the lever arm 18.

The cycle is repeated.

When moving to another pipe diameter, the movable abutment 7 moves along the shaft 5 relative to the abutment 6 over a distance, ensuring the separation of one pipe 4. Moreover, by shifting the frame 12 in a vertical plane, the axes Oi and Oa are aligned in the described manner.
