Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the Invention The present invention electrically performs the function of preventing unauthorized unlocking of the disabling piece and disabling element used in a conventional continuous ticket blocker, thereby preventing the lower handle from being unlocked. This invention relates to a device that prevents correct locking and locks from being fully opened or partially opened.

(2) Description of the Prior Art The continuous blockers are installed at the stations at both ends of the block section, and the continuous blockers of either station are installed at the stations at both ends of the block section. Take out one vote,
This is issued to the train as proof of operating permission to ensure safe block operation.

The consecutive tickets stored in the consecutive ticket blocker 1 are taken out to the outside by operating the drawer of the lower puller provided on the box body, but this lower puller is not fully opened for the consecutive ticket blockers at both stations. In addition, because one station and the other station handle the work jointly, there may be situations where predetermined operating procedures cannot be followed, such as when the bottom handles of the connecting blockers at both stations are both half-open. (If the bottom handle is half open, you can see half of the consecutive tickets, but you cannot take them out. This state means that you have approved the train coming from the other station.

) is necessary to prevent this. The release piece and release element have an important function of preventing unauthorized unlocking, as well as preventing failures such as unauthorized opening of both sides of the inner lower handle, full opening of both sides, and half opening of both sides. Next, the operation and operating procedure of the continuous blocker in relation to the operation of the control piece will be explained with reference to FIG. In addition, the control piece 1 is the second
As shown in the figure, half of the fully open key 2 is screwed onto the locking groove 3 and attached to the lower puller 4. In Figure 1, A
When a train departs from a station to station B, station A first transmits a localization transmission signal to station B using transmitting power P□ in order to obtain approval for train departure. At station B, as part of the approval procedure, the unlocking type ken P2 is used to pull out the lower handle 4 half-open, and then the transmitter holder Pl is used to send a half-open transmission signal to station A. At Station A, the receiving relay 5 is operated in response to this signal, and the horizontal line wheel 6 is energized to lift the fully open key 2. When the fully open key 2 is lifted up, the half open key 7 supported at its tip is lifted up in conjunction, and the lower handle 4 is unlocked and can be pulled out. When the lower puller 4 is pulled out from the normal position in the direction of full opening, the release piece 1 moves with the releaser 8 placed on the full open key 2 to keep the full open key 2 lifted, and the lower puller 4 is moved. To prevent a fully open key 2 from falling and being locked in a half-open position even if the transmission current is cut off while the lock is pulled out from the normal position to fully open. When the lower handle 4 approaches full opening, the release element 8 closes to the release piece 1.
into the groove 3 of the lower puller 4 through the groove H, and forcibly suppresses the fully open key 2 so that it cannot be lifted up, and also breaks the interlocking relationship between the fully open key 2 and the half open key 7, causing the half open key 7 to fall. The lower handle 4 is locked at the fully open position. As a result, once the lower handle 4 is fully opened, even if the horizontal wire wheel 6 is excited by continued transmission from station B, the full-open key 2 will not be lifted and the lower handle 4 cannot be moved from the fully open position.

At this point, only one consecutive ticket is taken out from the consecutive ticket blocker at A station, carried to B station, and delivered through the upper puller 9 to the Torihigashi blocker at B station. As a result, the lower handle 4 of station B can be placed in the normal position.

Next, when the transmitter P8 at station B is used to send a localization transmission signal to station A, the receiving relay 5 at station A is activated and the vertical line ring 1 is activated.
0, the half-opened claw 7 is lifted up, and the lower handle 4 is unlocked. When the lower handle 4 at station A is pushed from the fully open position to the normal position, the locking element 8 escapes from the groove H and is supported on the locking piece 1, thereby lifting the full opening key 2. Since the half-open key 7 is lifted by its edge by lifting the fully open key 2, even if the transmitting current is cut off while the lower puller 7 is moving, the half-open key 7 will not fall and become locked in the half-open state. . Once the lower puller 4 is in its normal position, the release lever 8 falls from the release piece 1 and is locked with the full opening key 2, so the transmission from station B continues and current is applied to the vertical track ring 1°. flows, and even if the half-open key 7 is lifted, the lower handle 4 cannot be fully opened. In the figure, reference numeral 11 denotes a polarity reversal device, which is provided on the lower handle 4 and is used to reverse or interrupt the polarity of the transmitted current for each station depending on the position of the lower handle 4.

(3) Problems with the Prior Art Next, with reference to FIGS. 1 and 2, the meaning of the shape of the dissolving piece and its problems will be explained with reference to FIG.

The plane surface of the first stage in Fig. 3 serves one of the functions necessary to prevent the lower handle 4 from being opened both half-opened, fully opened, or to take out a large number of consecutive bills, and to ensure full-opening operation control. This is an important part.

If there is no west face and a ■ face is provided directly from the tip,
When one station is fully opened in response to a half-open transmission from the other station, if the transmission from the other station stops at the moment the lock 8 gets on the west side, release the unlocking type ken P2 at the first station. When the fully open key 20 is launched, the half open key 7 is lifted once and unlocked, and the fully open key 2 falls before the half open key 7, so if the lower puller 4 is pulled during that short period of time, the release button 8 is released. The lower handle 4 is locked in a half-open position by the half-open key 7 which sinks into the underside of the disassembled piece 1 and falls later.

As a result, both stations are half-open, causing problems.

When the trench is extended to the west side and the bottom handle 4 is returned to its normal position from fully open, the polarity changer 11 is activated before the release button 8 falls from the front edge of the cloth surface. As a result of the stereotactic contact, the consecutive slips fall onto the tray 4a of the lower handle 4, causing a problem in which the entire slip or two or more slips cannot be taken out.

Even if a west face is provided on the first stage, if the lower puller 4 is pulled strongly while the restrainer 8 is on the west face, if the restrainer 8 is placed on the river surface of the second stage. If it were to slide up, the lower handle 4 would be between the two stations, which would be an obstacle, such as making it possible to take out two or more consecutive tickets without joint operation by both stations, and the CD surface would be shortened due to wear etc. It becomes like this,
Also when the operating gap between the release piece 1 and the release element 8 becomes large, a failure of both half-opening is likely to occur.

In short, since the shape and dimensions of the disabling piece 1 have a significant effect on the function of the block blocker, various studies have been conducted on its design.
Although the shape of ~(j) is being considered.

It is difficult to judge the superiority or inferiority of these shapes when it comes to rice. If we focus on preventing both half-opening, it will cause trouble between both half-opening, and it is difficult to ensure perfection even though there are two. Incidentally, the shapes used for the disabling pieces of current continuous blockers are mainly (h) or (i).

Although various shapes of the release piece have been devised in this way, the reason why the perfect shape has not yet been determined is due to a transient phenomenon caused by the mechanical interlocking of the fully open key and the half open key. Another reason is that the mechanical interlocking function of the release piece and the release button cannot follow the timing of transmission and unlocking operations and the operating speed of pushing in or pulling out the lower handle.

(4) Explanation of the principle and operation of the invention Therefore, the present invention eliminates the interlocking relationship between the full-open key and the half-open key so that they operate separately, and replaces the mechanical interlocking mechanism of the release piece and the brake shoe with a switch and a relay. By replacing it with a combinational electrical control circuit, the operation of both keys can quickly follow the operating speed of the lower handle and the timing of transmission and unlocking operations, thereby preventing failures when the lower handle is fully open or partially opened. be.

(5) Structure of the Invention In other words, the present invention involves engaging a half-opening key with a lower handle that is pulled out from a box of a continuous ticket blocker to take out the consecutive tickets stored in the box one by one, so that it can be opened in its normal position, half open, or fully opened. A half-open key engagement groove that locks in position and a full-open key retaining groove that engages the fully open key between the normal position and the half-open position are provided, and the half-open key and the fully open key can be engaged in and released from each of the grooves. Connect the drive solenoids that are controlled individually, and connect each solenoid to the power circuit via the relay contact of the constant reverse position holding relay. At the same time, connect the lower handle to the power circuit of the constant reverse position holding relay by fully opening from the normal position. a pull-out detection switch that detects the normal position and operates the constant reversal holding relay when pulled out in the normal direction; and a push-in switch that detects the fully open position and operates the constant reversal holding relay when pushed from fully open to the normal position. It is characterized by being provided with a detection switch and a lock detection switch that detects a change in movement of the lower handle between the normal position and full open position, or between full open position and normal position, and causes the constant reverse position holding relay to self-hold during that time. It is something to do.

(6) Detailed description of this invention Embodiments of the present invention will be described below with reference to the drawings.

FIG. 5 shows a continuous block blocker to which the device of the present invention is applied. In the box body 12, there is a voltage detector G1 transmitting voltage Pl, an unlocking type P2,
An upper handle 9 and a lower handle 4 are provided, and a consecutive ticket M is delivered into the box body 12 through the upper handle 9, and this consecutive ticket M is sent to the consecutive ticket gutter 1.
3, and under certain conditions through discussions and joint work with the partner station, the lower puller 4 is fully opened, and the consecutive tickets M are taken out one by one from the consecutive ticket gutter 13 and dropped onto the receiving tray 4a. The one point marked is exactly the same as before. FIG. 6 is an example of a control circuit. On the lower handle 4, there is a half-open key locking groove S□+S2*S3 in which the half-open key 7 is dropped and locked in the normal position, half open position, and fully open position, respectively, and the normal position,
A full-open key retaining groove R for engaging the full-open key 2 between the half-open and half-open positions is provided. The half-open key 7 and the full-open key 2 are respectively supported so as to be movable up and down, and the half-open solenoid SM for vertical driving is connected to the half-open key 7, and the full-open solenoid belly for vertical driving is connected to the fully open key 2. . MS2 is a lock detection switch, MS3 is a drawer detection switch, and MS is a push detection switch. Drawer detection switch MS is lower puller 4
This is a switch that operates by detecting the normal position of the lower handle 4 when the lower handle 4 is pulled out from the normal position to the fully open direction. This is a switch that operates by detecting its position. The lock detection switch (2) is a switch that operates by detecting a change in movement of the lower handle 4 while it moves between the normal position and the fully open position or between the fully open position.

Both switches are controlled by the shapes of cams C2 to C4 attached in the longitudinal direction of the lower handle 4. A specific example of arrangement is shown in FIG. NR8R is each switch MS2~M
This is a constant reverse position holding relay that operates with the output signal from S. This constant reverse position holding relay NR8R controls the half-open solenoid SM and the full-open solenoid, and the wiring diagram of the control circuit is shown in FIG. In other words, constant reverse holding relay NR8R is installed in each solenoid SM and rain power supply circuit.
A constant reverse position holding relay NR8 is installed with a lifting contact nrsr.
The power supply circuit of R includes a pull-out detection switch MS3, a push-in detection switch λ/fS4, and a lifting contact n that constitutes a self-holding circuit.
rsr and lock detection switch MS2 are connected in parallel. Note that lrr and lnr are lifting contacts of receiving relays LRR and LNR, which will be described later. Contact 1rr
is connected in series with switch MS3, and contact 1nr is connected in series with switch MS. In addition, the control circuit includes a reception relay LN that operates by receiving localization transmission from the other party.
Receiving relay LRR operates upon receiving half-open or full-open transmission from R and the partner unit, and is raised by operating the unlocking type ken P2, and issues an unlocking command according to the polarity of the transmitting current of the partner unit and the status of one station. An unlocking relay P2PR that outputs a lock, and a polarity reversal detection switch M that detects the normal position, half open, and fully open position of the lower handle 4.
A polarity reversal relay PCB that switches the polarity of the transmission signal by operating S t and the switch MS, and a serial delivery memory relay that selectively drives the half-open solenoid SM to unlock the half-open key 7 at the time of serial delivery. TDSR, a delivery detection switch TD that detects the rotational displacement and restoring operation of the continuous ticket tongue 14 provided on the continuous ticket gutter 13 and operates the continuous ticket storage relay TDSR, and a delivery detection switch TD that operates the continuous ticket storage relay TDSR; It is equipped with a transmitting circuit cutoff a TSC consisting of an AND circuit at the output of the fall detection switch SL of the key 7, as well as a signal oscillator 5OC1 telephone equipment, etc.

In the above embodiment, conventional mechanical components are replaced with electric circuits as much as possible, but each detection switch MS2 to MS
4. Two NR8R half-open solenoid SM that maintains constant reverse position,
Except for the full-open solenoid, the other control circuits may be conventional ones.

Next, the present invention will be explained in detail. The operating instructions and procedures are exactly the same as the current continuous blocker.

When a half-open transmission is received from the other party, contact 1rr of reception relay LRR is configured, so in FIGS.
R is energized, energizing the half-open solenoid SM and °, the fully open solenoid version through its contact nrsr, and the half-open key 7 and the fully open key 2 are activated by the operation of both solenoids SM and RM.
and is snatched up. When the lower puller 4 is pulled out from the normal position to fully open, the lock detection switch MS2 is activated just before the half-open lock retaining groove S1 at the normal position passes directly under the half-open key 7, and the lock detection switch MS2 operates through the switch MS2 from the normal position to the fully open position. , the constant reverse position holding relay NR8R is self-held, and then the draw-out detection switch MS3 is opened. Therefore, even if the current transmitted from the other party is cut off during this time, the half-open key 7 or the fully open key 2 will not fall and become locked in the half-open position. When the lower puller 4 is pulled out further, the lock detection switch MS2 is opened at the position just before the continuous slip can be taken out, the constant reverse position holding relay NR8R falls, and the half-open key 7 is moved to the fully open engagement groove S.
3, the lower puller 4 is locked at the fully open position. Once the lower puller 4 is fully opened, even if it continues to receive a half-open transmission signal from the partner part, the drawer detection switch MS is open, so the constant reverse position holding relay NR8R does not operate, and the lower puller 4 is kept in the fully open position. It cannot be moved from

Only one consecutive ticket is taken out from the lower handle 4, delivered to the train, and transported to the other party. The other party receives the consecutive votes,
When this is delivered to the continuous block blocker, the lower handle of the mating part can be placed in the normal position.

Next, when receiving localization transmission from the other party, the receiving relays T and N
The contact 1nr of R constitutes, and the constant reversal holding relay NR8R is energized through the push-in detection switch f'MS4, the half-open solenoid SM and the full-open solenoid zone operate, and the half-open key 7 and the full-open key 2 are lifted. When the lower puller 4 is started to be pushed in the normal direction from the fully open position, the lock detection switch M is activated immediately before the half-open key 7 passes directly under the fully open half-open key engagement groove S3.
s2 operates, and the constant reverse position holding relay NR8R is self-held from fully open to normal position through the switch MS2.
Then, the push detection switch MS4 is opened. Therefore, even if the transmission current from the other station is cut off during this time, the half-open key 7 or the fully open key 2 will fall and the lower handle 4 will fall.
is never locked half-open. When the lower handle 7 is pushed further, the lock detection switch MS2 is opened just before the continuous ticket falls from the continuous ticket gutter 13 onto the tray 4a, the constant reverse position holding relay NR8R falls, and the lower handle 4 is locked half-open. At 7, the stereotaxic position is locked. Once the lower handle 4 is locked in the normal position, even if the transmission from the other station continues, the constant reverse position holding relay NR8R will not operate as long as the push detection switch Ms3 is open, and therefore the lower handle 4 will be fully opened. cannot be returned to.

Figure 9 shows the engagement groove provided on the lower handle and each detection switch 4.
shows the relationship with the operating timing. In the embodiment, the lock detection switch Ms2 and the push-in detection switch MS4 use a lift-up contact (2), and the draw-out detection switch MS3 uses a drop contact (2).

(7) Effects of the Invention As described above, the present invention uses an electrical control circuit consisting of a combination of a switch and a relay in place of the conventional mechanical interlocking mechanism consisting of a combination of a disabling piece and a disabling element. Since the half-open key and the full-open key operate separately, there is no delay or timing shift due to mechanical interlocking, and there is no change in transmission from the other station, the timing of the unlock operation, or changes in the operating direction or position of the bottom handle. It is possible to drop and pick up half-open and fully-open locks in an immediate response, and it completely eliminates the unauthorized unlocking of the lower pull of the blocker between one station and the other station, as well as the failure of the two half-open locks. It can be prevented.

Therefore, the present invention has the effect of significantly improving the reliability and security of the block blocker.
