SU26469A1 - Recording counter of boards passing through edging machines - Google Patents

Description

In the proposed self-recording counter of the boards passing through the trimming machines, a number of electromagnets are used, from the co-zig, the current is closed in some electromagnets using rotary and lever contacts, depending on the thickness, width and length of the board. When current is closed, the levers of electromagnets print on a moving tape a certain number of lines corresponding to the size of the board.

In the attached drawing, FIG. 1 is a front view of a counter; FIG. 2 shows the electrical equipment of the meter; FIG. 3 is a top view of the lower part of the counter; FIG. 4 is a side view of a wheel winding a ribbon.

The counter consists of a series of electromagnets M (Figs. 1 and 3) with the corns I, the levers In which they carry wheels or pins l at their ends which, when the current closes in electromagnets, print dashes on the tape H rewinding from the drum on the drum ulz.

The current from the battery I (Fig. 2), directed to the electromagnets Afj, M1, ...., meets switch L on the way; entering terminal 2 of the switch, the current through the brush U goes to terminals 1, 3, 4, 5 and 6; From terminal 1, the current enters the switch G and the electromagnets Mj and Afio, and from terminals 3, 4, 5 and 6-- to the electromagnets M, M, M and M, From the switch G, current flows through terminals 8, 9, 10 and 11 to the electromagnets MI, Mi, MS, and M. On the output of the electromagnets MI, MI, M, M, MB, Afs, M, MS and MIO, the current is directed through a rotating contactor switch B back to the battery; upon exiting the electromagnet, the MDC returns to the battery through the contact E located at the end of the movable lever I. Brush U of the switch A is connected to arm 3 supporting the corrugated drum / ff of the trimming machine. The brush H of switch G is connected with the help of levers with lever L, which serves to dilute the saws of the machine by the size of the width of the board.

In the absence of a board in the machine, the W roll is in the lower position; at the same time, in switch A, terminal 2 is separated from other terminals and, therefore, the current in the entire circuit is interrupted.

When the board passes through the machine, the roller / IG, lifting to a certain height depending on the thickness of the board, acts through the arm 3 on the brush D of the switch L, which is placed in a certain position, whereby the current is directed to some of the

magnets M, MS, MI to MS, as a result, when current is closed by contact D, one, two, three or four dashes are put on the moving tape, which determine the thickness of the board.

Lever L takes one position or another depending on the width of the board; at the same time, the commutator / directs the current to some of the electromagnets MI, 71/2, M3, A / 4, which, when the contact D is closed, imprint on the tape a known number of dashes indicating the width of the board.

The electromagnets of the L / e and / jfjo current from switch A are supplied at a high thickness of the board passing through the machine.

Rotating contact F is frictionally coupled to one of the machine tool feed rolls, and this friction link is made with the help of the upper corrugated roller W, which, when it passes the board, connects the friction clutch of the contactor and the roller. If there is no board in the machine, the contactor E s rotates. If there is a board in the machine, the chains of all electromagnets, except for the electromagnet Md, close the switchgear once, as the board passes a certain part of its length, and, therefore, the longer the board, the greater the number of transverse lines consisting of one or another number of lines. moving tape. Contact E closes the current in the circuit of the electromagnet Mf only once during the passage of the board through the machine, namely when the co-ax approaches the feed rollers.

Electromagnet M periodically attracts its measles I (Fig. 4), and the lever P with the help of the dog C rotates

the ratchet wheel X, and with it the llfz drum, on which the tape H is being wound (FIG. 1),

The subject matter of the invention.

Claims (4)

1. Self-recording counter of boards passing through edging machines, characterized in that for the purpose of recording boards a rotating contact D is used, periodically closing electromagnets and frictionally coupled with one of the feed boards of the machine’s rollers when the board passes under the upper corrugated roller G, supporting the shoulder 3 of which is connected by an elastic pull with a shoulder bearing contact D (Fig. 2). 2. In the meter according to claim 1, use, for the purpose of recording the thickness of the boards, of the switch L, which serves to turn on, depending on the thickness of the dogma, a greater or lesser number of electromagnets MS - MS, with the help of a brush / controlled by a shoulder 3, supporting corrugated W roller (Fig. 2).  3. In the meter of claim 1, use, for the purpose of recording the width of boards, of switch G, which serves for switching on, depending on the width of boards, greater or. a smaller number of electromagnets Afj-Mi through the brush H, controlled by the lever L, which serves to dilute saws by the value of the width of the board (Fig. 2). 4. B counter according to claim 1 application, for the purpose of recording the number of boards passed through the machine, of the contact E, which serves to close the electromagnet Ma when the end of each board approaches the feed rollers (Fig. 2).
