Description

The subject of the invention is an electric outboard transport device with selective control of the traveling arrows by means of adjustable contacts mounted on the casing of the trolley.

In electric overhead transport devices, the selective control of track arrows is of great importance in order to direct the trolley from the main track to any branch and from the latter to any of the branches adjacent to it. This is particularly relevant for transport devices, which are located indoors and have a large number of branches (for example, for transport devices in book storages).

The described device makes it possible to control the direction of the arrows at any location of branches. A distinctive feature of the device is that the trolley is equipped with a fixed roller and special adjustable contact rollers mounted on the rod, and the trolley electric motor is powered by roller current collectors. By means of a fixed contact roller and one adjustable contact, they control the arrows of the main path, and with the second a reversible contact together with the first contact controls the branch arrows.

FIG. 1 shows a side view of the trolley; in fig. 2 is a front view thereof; Fig. 3 is a power supply diagram of the entire device; in fig. 4 is a graph of contact positions; in fig. 5 - power supply node.

The numbers Y, 2, 3, 4, 5, and 6 denote, respectively, the electric motor, the roller current collectors for powering the electric motor, the carriage roller, the shtanga, the upper and lower movable contacts.

As can be seen from the power scheme of the whole device (Fig. 3), the contact network for powering electric motors is divided into sections L, M, etc., which are connected to the main line by means of switches S |, 82, etc., actuated when the contacts are closed, P, 2, etc. In addition, in parallel with the contact network before branch NO 60925

An additional contact A, 6, B, 1 D E, 3 wires connected to the circuit of the corresponding switch controlling the current supply to the electromagnetic mechanism C for turning the switch are laid.

The device operates as follows.

The trolley moves from left to right and, after passing section M, the contact network of the electric motor, hits section M. At the same time roller 3 of the carriage (Fig. 1 and 2) closes the contact wires PI, the BI switch is activated by turning off section MI. When the carriage moves further (to the right), the roller 3 enters the contact wire PZ and at the same time the movable contact 5 to one of the contact wires

A, B, C, D, E, E, 3. Since the roller 3 and the movable contacts 5 and b are connected by wire, a switch 62 is turned on, which in turn turns on the electromagnet C of the switch mechanism, and the arrow translates . Placing one or a part of the contact wires A, B, C, D, D, E, 3 at the switch makes the switch mechanism work only in those cases when the position of the upper moving contact 5 coincides with the position of these additional contact wires. Thus, the trolleys with the misaligned position of the upper movable contact 5 will pass from the site to section M-, and M, where roller 3 will close contact wires 4, then switch B will operate a second time and turn on section / I, allowing the next carriage advance to the arrow.

In the case when the carriage makes a switch of the arrow on the branch, the turning (arrow) segment of the section MZ, detaching its connecting contacts from the current / Out section of the current, stops the car until it again contacts the same connecting contacts MS section under current. Pass to the branch (section MP), the trolley roller 3 closes the contact wires PS; at the same time, the BZ switch (the second time) is turned off, the electromagnet C is turned off (the arrow mechanism) and the spring returns the arrow to the forward direction. Continuing its movement, the trolley gets to the section Me, where the roller 3 closes the contact wires PS, then the switch fii is activated and turns on section M for the passage of the next trolley.

Due to the fact that the same position of the upper movable contact 5 corresponds to several positions of the lower movable contact 6, it is obvious that one additional contact wire for controlling the transfer mechanism will work for several combinations of the position of the movable contacts.

FIG. 4 shows a graph of possible combinations (/, 2, 3, 4, 5, 6, 7, 8, 9, 10, II, 12, 13, 14, 15, 16, 17, 18; 19; 20; 21) positions of two movable contacts of the trolley. When breaking down the rod 4, on which they move, into 7 parts.

For the top contact, these positions are marked with the letters A, B,

B, D, D, E, 3, and for the lower contact - the numbers L //, ///, IV, V.

P - contact wire corresponding to the position of the roller 3.

For the given electric circuit of the transfer arrow, the presence of one contact wire A causes the mechanism of the arrow to operate for the six positions of the bottom contact. The second arrow with the contact wire B removes five trolleys, the third arrow with the contact wire C pulls four trolleys, etc.

The switch can also be carried out with the help of contacts 5 and b (Fig. 5). For this or that combination

the positions of both moving contacts are respectively located two contact wires: A for the upper contact 5 and /// for the lower contact 6. Obviously, of all the combinations of the contact positions, only one combination can turn on the switch B through this pair of contact wires, will turn on the magnet C mechanism arrows. Pass the arrow, the trolley roller 3 closes the contact wires PS, then switch off, switch off magnet C, and the arrow returns to its original position.

If you combine these methods, you can take the trolley to the sideline with a certain number of combinations of movable contacts or, in other words, you can put a certain number of stations on this sideline.

PREd. M with t inventions

Electric suspension transport device with selective control of traveling arrows by means of adjustable contacts mounted on the casing of the trolley, characterized in that, with the aim of doubling the trolley twice, namely: from the main path to any branch and from the latter to any of the adjacent branches equipped with three electrically connected contacts, of which the stationary contact together with one adjustable contact controls the arrows of the main path, and the second one The contact together with the first one controls the branch arrows.
