Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voucher delivery detection device in a voucher blocker, which is intended to monitor the delivery status of vouchers delivered into the voucher blocker and prevent unauthorized unlocking of the lower handle. It is.

Passport blockers are installed at each station at both ends of the block section, and through consultation and joint operation between both stations, only one pass for that section is taken out of the passblocker at either station and used as proof of driving permission. It is issued to trains to ensure safe block operation.

The ticket taken out from the ticket blocker at the departure station is delivered into the ticket blocker at the arrival station. Once the ticket is properly delivered, the bottom handle at the arrival station can be placed in the correct position, and a signal from the arrival station can be heard. In response to the transmission, the lower handle of the ticket blocker at the departure station can also be placed in the correct position. However, conventional ticket closures have a structure in which the lower handle is mechanically unlocked using the weight of the ticket as a power source, which has caused various problems.

That is, in FIG. 1, in the conventional slip blocker, a slip M inserted into the container body 2 through the upper handle 1 falls onto the slip tongue 3, and the slip tongue 3 is directed downward under the weight of the slip M. Rotate. Due to this rotational displacement, the vertical pin 4 rises, pulls up the half-open hook 5 connected to its lower end, unlocks the lower puller 6, and drops the support lock 7, causing the vertical pin 4 to rise.
The half-open key 5 is held in an unlocked position. Next, when the lower puller 6 pulled out half-open is pushed into the normal position, the support of the vertical link 4 by the support lock 7 is released, the half-opening key 5 falls, and the lower puller 6 is locked in the normal position. However, the ticket M
When it sticks to the slip tongue 3 and does not fall into the slip gutter 8, the lower handle 6 is not locked and can be freely moved between the fixed position and the half-open position. Therefore,
During the next handling, the lower handle pulled out to the fully open or half open position can be freely returned to the normal position without joint operation with the other station.
This means that when the departure station receives the ticket retrieval signal,
This means that you can take out your ticket as many times as you like at the departure station. As a preventive measure, current ticket blockers are equipped with two brass rails on the surface of the ticket tab 3 to allow the ticket to slide smoothly. It is impossible to completely prevent sticking. Furthermore, as long as a mechanical operating mechanism is used, it is impossible to avoid unauthorized unlocking of the lower handle due to malfunction of the mechanism. Needless to say, if two or more tickets are taken out within one block section, it is extremely dangerous as it could lead to a train rear-end or collision.

The present invention solves the above problems and monitors the delivery status of the ticket inserted into the container through the upper handle, and when the ticket sticks to the ticket tongue, the lower handle cannot be pushed into the correct position. Therefore, the present invention provides a device which prevents two or more slips from being taken out due to unauthorized unlocking. That is, the present invention provides a form blocker equipped with a form tongue that senses a delivered form through an upper handle and controls a half-unlocking key to unlock a lower handle, in which the rotational displacement of the form tongue due to a fall of the form is prevented. a delivery detection switch that detects a delivery detection switch, a delivery delivery storage relay that self-holds a contact point by the operation of the detection switch, and a half-open solenoid that drives the half-open key, and a delivery delivery storage relay that drives the half-open key. This is a slip delivery detection device in which the lifting contact of a relay and the falling contact of a slip delivery detection switch are connected in series.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 2 shows a slip blocker to which the device of the present invention is applied. The container body 2 is provided with a voltage detector G, a transmitting voltage detector P ₁ , an unlocking voltage detector P ₂ , an upper handle 1 and a lower handle 6,
Deliver the slip M into the container body 2 through the upper handle 1,
The vouchers M are accumulated in the voucher gutter 8, and the lower puller 6 is fully opened under certain conditions through a meeting and joint work with the partner station, and the voucher M is deposited in the voucher gutter 8 into the receiving tray 6a.
This is the same as before in that the received slips M are taken out one by one. Directly above the voucher gutter 8 is installed a voucher tongue 3 which rotates under the weight of the voucher M inserted into the container body 2 through the upper handle 1 and returns to its original position after passing through. FIG. 3 is a control circuit diagram. There are half-open locking structures S ₁ , S ₂ , and S ₃ on which the half-open key 5 is dropped and locked in the normal position, half-open position, and fully open position, respectively, and the full-open key 9 is engaged between the normal position and the half-open position. Fully open key engagement groove R
is provided. The half-open key 5 and the full-open key 9 are respectively pivotally supported in the container body 2 so as to be able to move up and down separately, and are normally engaged in the grooves. It is driven by a full opening solenoid RM and is pulled up from within each groove to unlock the lower pull 6. When the full-open solenoid RM receives a transmission signal (half-open transmission, normal position transmission) from the partner station, when the lower puller 6 is pulled out from the normal position to fully open or when it is returned from the fully open position to the normal position, the unlock pushbutton P ₂ must be operated. works with the half-open solenoid SM,
Although the fully open key 9 is lifted up, a detailed explanation of the operation will be omitted.

In addition to the above, the half-open solenoid SM operates when the lower puller 6 is set to half-open from the normal position or from half-open to the normal position upon receiving a positional transmission from the partner station, when the unlock pushbutton _P2 is operated, and when the slip is delivered. and lift up the half-open key 5. The present invention deals only with the operation of the half-open solenoid SM at the time of ticket delivery. In FIGS. 2 and 3, a cam 10 is integrally provided on the rear edge of the slip tongue 3 supported by a shaft 3a so as to be movable up and down, and a delivery detection switch is mounted opposite to the cam 10.
Place TD. Delivery detection switch TD is slip M
falls onto the slip plate 3, and when the slip plate 3 rotates downward under the weight, the rotational displacement is sensed and a contact point is formed, causing the slip M to fall into the slip gutter 8. When the slip tab 3 returns to its original state, the contact of the delivery detection switch TD is opened. TDSR is a voucher delivery memory relay that operates according to the contact configuration of delivery detection switch TD. In the wiring diagram in Figure 4,
The lift contact (TD _NO ) of the delivery detection switch TD is connected in series to the power supply circuit of the slip delivery memory relay TDSR, and the relay contact (TDSR) of the slip delivery memory relay TDSR is connected to the contact (TD _NO ) of the switch TD.
is connected in parallel with the TDSR to form a self-holding circuit for the receipt delivery memory relay TDSR. In addition, the control circuit includes a reception relay LNR that operates upon receiving the localization transmission from the other station, a reception relay LRR that operates upon receiving the half-open or full-open transmission from the other station, and a reception relay LRR that operates upon receiving the localization transmission from the _other station. The unlocking relay _P2PR issues an unlocking command according to the polarity of the transmitting current of the other station and the state of the own station, and when the lower puller 6 is pulled out from the normal position to the fully open direction, When the drawer detection switch MS ₃ and the lower puller 6 are pushed in from the fully open position to the normal position, the push-in detection switch MS ₄ and the lower puller 6, which operate by detecting the fully open position of the lower puller 6, will move between the normal position and the fully open position. Alternatively, the lock detection switch MS ₂ operates by detecting the change in movement between fully open and normal position, and is excited by the operation of each switch MS ₂ to MS ₄ , causing the half-open solenoid SM and fully open solenoid RM to fall. , a constant reversal holding relay NRSR that controls lifting, and a polarity reversal detection switch MS ₁ that detects the normal, half-open, and fully open positions of the lower handle 6.
It is composed of a polarity reversing relay PCR which performs polarity reversal switching of the transmission signal by the operation of the switch MS ₁ , and an AND circuit of each relay output and the output of the half-open key 5 fall detection switch SL, and one of them is activated. The station is equipped with a transmitter and disconnector TSC that cuts off transmission from the own station to the other station when the station is in transit, but since these are functionally the same as conventional ones, a detailed explanation will be omitted.

In the example, the stations at both ends of a block section are A station and B station, and when a train departs from A station to B station, the ticket block at B station is blocked according to a certain procedure by joint operation of both stations. The lower handle 6 of the device is unlocked, and it is pulled out from the normal position to a half-open position. In the half-opened state, half of the ticket M can be seen, but cannot be taken out. This state means that the train coming from A station has been approved. Next, based on the transmission signal emitted from station B, the lower handle 6 at station A is pulled out fully, and the ticket M is taken out from the ticket blocker at station A through the lower handle 6, and the ticket M is delivered to the train. and transported to B station. When the ticket M is received at station B and delivered to the ticket blocker through the top handle 1, the ticket M that falls from the top handle 1 collides with the ticket tab 3, which receives its weight and rotates downward. move. This displacement first operates the delivery detection _{switch TD} , and as shown in FIG. ) is configured. The relay contact (TDSR) is installed in the power supply circuit of the receipt delivery memory relay TDSR and the half-open solenoid SM.
The delivery memory relay TDSR is self-held through its contacts (TDSR), but the half-open solenoid SM
does not operate because the drop contact TD _NC of the delivery detection switch TD is open. When the voucher M slips on the voucher tongue 3 and falls into the voucher gutter 8, the voucher tongue 3 returns to its original position and the lift contact of the delivery detection switch T is activated.
TD _NO is open, falling contact TD _NO is configured,
The half-open solenoid SM is energized, and the half-open key 5 is lifted to unlock the lower handle 6. Since the slip delivery memory relay TDSR is self-retained, the lower handle 6 is maintained, and the lower handle 6 can be placed in the normal position rather than half-open. At this time, the fully open key 9 is in the engagement groove R.
Since it has fallen inside, it cannot be pulled out fully. When the lower puller 6 is pushed into the normal position, its power circuit is opened just before the lower puller 6 reaches the normal position, the half-open solenoid SR is demagnetized, the half-open key 5 falls, and the lower puller 6 is locked in the normal position. In the case of the embodiment, the lock detection switch is located at the position immediately before the lower puller 6 reaches its normal position.
The circuit is configured so that it is detected by MS ₂ and the power supply circuit is opened by the operation of the constant reverse holding relay NRSR, but when it is used by the current ticket blocker, it is locked by mechanical operation. The above is a case where the delivery of the voucher is carried out normally. However, if the voucher M delivered through the upper handle 1 sticks to the voucher tongue 3 and does not fall into the voucher 8, the voucher tongue 3 rotates downward. The contact (TDSR) of the receipt delivery memory relay TDSR is closed, but the drop contact TD of the delivery detection switch TD remains dynamically displaced and does not return.
Since _NO is open, a half-open solenoid
The SM is not energized, and the lower handle 6 is therefore not unlocked. In other words, even though the ticket received at Station B was delivered to the ticket blocker, the lower handle 6, which had been pulled out half-open, could not be placed in the correct position, and it became known that an abnormal situation had occurred. Appropriate measures can be taken to immediately restore normalcy.

As described above, the present invention, after a ticket delivered to the ticket blocker through the upper handle passes over the ticket tab, waits for the ticket tab to return and then energizes the half-open solenoid to lift the half-open key. Because the lower handle is unlocked, in the event that a ticket sticks to the ticket tab and does not fall into the ticket gutter, or if the ticket tab does not return to its original state due to malfunction, Unlocking of the lower handle is prevented, the handler can immediately know that an abnormality has occurred, and it is possible to prevent unauthorized removal of slips due to erroneous operation.

Therefore, according to the present invention, a dangerous situation such as two or more tickets being issued within the same block section does not occur, and the present invention has the effect of ensuring the safety of train operation in the block section. It is.
