SU1221086A1 - Conveyer for rolls - Google Patents

Description

The invention relates to transporting devices and is intended for transporting rolls of paper, cardboard, pulp in the pulp and paper industry.

The purpose of the invention is to increase the reliability of operation and avoid damage to rolls when passing through sprockets at the time of transfer to another vehicle.

FIG. 1 shows a conveyor, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3- section BB in FIG. 2; in fig. 4 - bracket; in fig. 5 - plate, front view; in fig. 6 is a view along arrow B in FIG. five.

The conveyor includes a frame 1, an electric drive 2 with an asterisk 3, a tension station 4 with an asterisk 5, an endlessly closed traction body in the form of a lamellar chain 6, a load-carrying fabric composed of M-shaped plates 7. The plates 7 on the end sides 8 have through holes 9 for the axes 10. The axes 10 are welded to the plates 7 in the area of the holes 9. The plates 7 with the apex of the depression 11 rest on the central part of the axes 10 and in this zone are mutually connected, for example by welding, which gives them stiffness and increases the load-dry ability. For the same purpose, the sides of the plates 7 are provided with flares 12. The plates 7 on the end sides 8 (except the holes 9) are provided with more through holes 13. Brackets 14 welded to the inner plates of the chain 6, made with a semicircle radius 15 10. The brackets 14 are provided with a through hole 16, which coincides with the holes 13 in the plates 7. A connecting element 17 is inserted into the holes 16 and 13, allowing the brackets 14 to communicate with the plates 7. The element 17 is made, for example, in the form of a rivet.

The end sides 8 of the plates 7 are provided with clamps 18 arranged with a minimum gap between the guides 19 of the frame 1. The locks 18, for example, are integrally formed with the ends of the plates 7, are like their continuation and serve together with the guides 19 the position of the plates 7 of the load carrying sheet during the operation of the conveyor.

At the ends of the axles 10, lubricators 20 and ball-bearing rollers 21 are mounted, rolling along working surfaces 22 of guides 19. Working surfaces 22 of guides 19 are angled relative to the longitudinal axis of the conveyor to ensure the stability of the conveyor belt.

The axes 10 are located strictly in the middle of the length of the internal links of the chain 6, thus eliminating the elevation of the angles 23 of the plates 7 of the load-carrying fabric above its horizontal

section at the transition of the plates 7 through the stars 3 and 5. The width of the plates 7 is selected depending on the step of the chain links 6 and 1.2 times more than the last. For example, when the pitch of the links of the chain 6 is 100 mm, the width of the plates 7 is 120 mm, i.e. the step size of the chain and the width of the plate of the load-carrying web are 100: 120. In the event of a change in the width of the plates 7, the transported rolls of paper are subject to deterioration (mechanical damage with breaking and removal of the upper layers) and the operating mode of the conveyor is disturbed.

The lower part of the radius cut-out 15 in the brackets 14 is located at the level of the plane of the upper edge 24 of the plates of the chain 6, which ensures the minimum size

0 according to the height of the construction of the carrying conveyor belt. The brackets 14 are made in the form of a trapezoid, the sloping side of which is installed with a gap to the outer plates of the chain 6, which ensures free rotation of the plates 7 when moving around the sprockets 3 and 5. The proposed form of the bracket 14 allows them to be produced with minimal metal waste. For the convenience of assembling the load-carrying fabric on the brackets 14, the hole 16 for the connecting

Q element 17 is located in the upper right corner of the brackets.

The conveyor works as follows. The transported rolls 25 roll onto the load-carrying web from the side of the platform or come from the end portion of the conveyor and are held by the M-shaped surface of the plates 7 of the load-carrying cloth. The load from the mass of the rolls is transmitted through the axles 10 and the ball bearings 21 to the guides 19. The brackets 14 under the reverse and connecting elements 17 perceive the thrust force. The presence of the lubricators 20 ensures the lubrication of the ball bearing rollers 21 without disassembly.

The reverse movement of the conveyor allows to expand the scope of its application,

For example, in production lines when sorting according to the quality and formats of rolls of paper, cardboard to the places where they are stored. When the width of the plates 7 is 1.2 times larger than the chain pitch, the elevation of the angles 23 of the plates 7 above the level of transportation is excluded.

0 rounding chain sprocket 3 and damage to the rolls angles 23 plates. When the width of the plates 7 is 1.2 times smaller than the pitch of the chain, the inclination of the front end of the roll and the emphasis of the ends of the roll into the elements of the receiving vehicle are excluded.
