Description

The invention relates to a design of a continuous transport device, namely, a gram of vitational distribution roller conveyors used for the transport service of technological lines. A gravitational roller conveyor is known that contains vertically movable sections associated with vertical movement mechanism 1. A disadvantage of this device is the lack of selectivity of addressing the load to a specific workplace due to the lack of information about the location of the load. The aim of the invention is to expand technological capabilities by addressing goods, for which the vertical movement mechanism contains a rod on which cams are mounted, each of which interacts with a corresponding vertical moving section associated with a ram cylinder equipped with a stroke counter, and in places of derailment cargo from the conveyor installed receiving sections and stackers. In this case, the cams are made in the form of eccentrics and mounted on the rod with a shift in the vertical plane one relative to the other by 180, or the cams are made flat with oppositely directed inclined surfaces. Figure 1 shows the gravitational roller conveyor, a general view; figure 2 - the same plan; in FIG. 3, view A; figure 4 is the same section along b-B; figure 5 is the same section along bb; Fig. 6 is an automatic addressing and distribution scheme; Fig. 7 is an embodiment of a gravity distribution roller conveyor with flat cams mounted on a rod. The proposed gravity roller conveyor contains spring-loaded lifting and lowering roller section I, installed using sleeves 2 and columns 3 on the frame 4 (see Fig.4). Each of the sections 1 by the rollers 5 rests on the cams b, either made in the form of eccentrics mounted on a common shaft 7 of the drive mechanism, or in the form of flat cams with opposing inclined surfaces mounted on the rod of the drive mechanism (see Fig. 7) ,

The drive mechanism, in addition to the common shaft or shaft, contains a ram 9 that is controlled by the spool 8 and is connected to the common shaft via crank 10. At the addressing points, the conveyor is equipped with receiving 11 and loading.12 devices for tilting roller sections as well as discharge devices 13, 14 - colliders; The device for automatic addressing of goods (Fig. 6) is performed on the stroke counter of the ram cylinder. The counter xcd is made, in particular, in the form of a block of relays 15 and 16 of pulse counting in parallel with contacts, respectively 15.1-15.2 and 16.1, the number of which depends on the number of address points. Connections 17.1 and 18.1 of the switches, which also have contacts 17.2 and 18.2, are connected in parallel to the input of this unit. In addition, switches 19, 20 and relays 21, 22 and executive electromagnets 23, 24 are connected in parallel to the contacts of the corresponding relays.

In parallel, a power cylinder control unit comprising switches 25, 26, contacts 17.2 and 18.2 of switches, relays 27, 15, 16, electromagnets 28, 29 is included in the automatic addressing and load distribution scheme.

The device addressing and distribution of goods, made on the counting of moves, can also be pneumatic, mechanical, electronic

The proposed gravity roller conveyor works as follows (in a double way.

The load 30 is installed on section 12 and the unloading address is set by activating the corresponding pulse counting relay configured for a certain number of pulses. If the lifting and lowering section 1 opposite the section 12 forms the lower part of the roller track, the packer 14 pushes the load onto the conveyor. After the actuator has returned to its initial position, the switch 27 switches on the relay 27 and turns on the spool control electromagnet 28; The power cylinder 9 automatically activates, in one stroke, the shaft 7 is turned 180 through the crankshaft 10 and opens the stroke control switch 17 of the power cylinder 9. At the same time, section 1, on which the load is located, moves upwards in the vertical plane, and the section following it in the course of its motion, resting on the eccentric displaced relative to the previous one by 180, is down. As a result

they also form a continuous inclined roller track, on which the load collides down all the way into the extreme roller of the next section. After the end of the stroke of the cusp, you, the switch 18, turns on the electromagnet 29 and the cylinder 9 turns backward with the shaft 7 turning 180. Section 1, on which the load 30 is currently located, is again

 is brought into a position in which

 it forms the upper part of the oolic path. The load 30 rolls to the next section. Thus, for each stroke of the power cylinder, cargo 30 is swept over a step,

5 equal to the length of the horizontal projection of section 1.

With each actuation of the switches 17.1 and 18.1 and, respectively, rotation of the shaft through 180 ° on the relay 21 and

0 22 pulses arrive. The load 30, after a certain number of strokes, enters a predetermined section 1, and a pulse counting account corresponding to a predetermined address, for example, 15, is triggered and switches the solenoid 23 of the interrupter 13 through the relay 21. to the starting position. If the load is addressed to another workplace, then the corresponding relay is triggered, on. example relay 16, and the process is similar.

For the second embodiment

 cams 6, mounted on a rod, flat with oppositely directed inclined surfaces (see Fig. 7), the addressing process is similar, with the only difference that

0 bar performs reciprocating movement in the horizontal plane. The rollers 5 of section 1 then roll over inclined surfaces, and the sections alternately form roller tracks. With each stroke of the rod there or back a switch 17 or 18 is triggered and the process occurs identically described.

The proposed design of a gravitational roller conveyor avoids the installation of address devices on the goods and address reading devices on the conveyor and, thus, significantly simplify the design and increase the reliability of operation. In addition, the absence of an electric drive, as well as the possibility of using a pneumatic scheme to control the conveyor, made

0 on the stroke meter, allows the use of a conveyor under increased explosion and fire hazards.
