Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for unlocking a locking mechanism of a loom without using a key plate.

BACKGROUND OF THE INVENTION Conventional technology looms are provided with an adjustment section that is preferably adjusted by a specific operator, such as a service person or maintenance person. For example, an adjustment section that performs filler sensitivity adjustment and various timing adjustments is housed in a control panel that has a lock mechanism. Therefore, the operator unlocks the locking mechanism of the control panel with the key plate, opens the door of the control panel, adjusts the adjustment section, closes the door of the control panel after completing the adjustment operation, and closes the door of the control panel. Lock the lock mechanism.

Problem to be Solved by the Invention When an operator adjusts the adjustment section, the locking mechanism of the control panel must be unlocked using a key plate. For this reason, factories with a large number of looms installed have as many key plates as the number of looms installed, and from among these many key plates, one key plate corresponding to the loom that requires adjustment is found and locked. The mechanism had to be unlocked, and the unlocking operation of the locking mechanism was troublesome.

Means for Solving the Problems An unlocking switch provided on a loom, an unlocking request signal transmitter provided on the loom and transmitting a specific unlocking request signal by turning on the unlocking switch; An IC card that receives a lock request signal, compares it with a plurality of pre-stored unlock request signals for each loom, and transmits a specific unlock command signal when it matches one of the unlock request signals, and an IC card installed in the loom. receive a specific unlock command signal,
A control unit that compares with pre-stored unlocking commands for the loom and outputs an actuator operation signal when they match, and a locking mechanism of the loom based on the actuator operation signal that is provided in the loom and output from the control unit. It is equipped with an actuator that unlocks the door.

When a worker carrying an operating IC card goes to a loom that requires adjustment and turns on the unlock switch, a specific unlock request signal is transmitted from the unlock request signal transmitter, and this specific unlock request signal is transmitted from the unlock request signal transmitter. The IC card receives the lock request signal. Then, the specific unlocking request signal received by the IC card is compared with a plurality of unlocking request signals for each loom stored in advance, and when it matches one of the unlocking request signals, a specific unlocking command signal is transmitted. When the control unit of the loom receives a specific unlock command signal sent by this IC card,
The specific unlock command signal received by the control unit is compared with previously stored unlock command signals, and when they match, an actuator operation signal is output. This actuator operation signal causes the actuator to operate and unlock the locking mechanism of the loom.

Embodiment In FIG. 1, ■ indicates a plurality of looms, 2 indicates a control panel provided in each of the plurality of looms l, and each control panel 2 has a door 4 that is locked and unlocked by a locking mechanism 3. Each control panel 3 houses an adjustment section (not shown) for adjusting filler sensitivity and various timing adjustments. Here, the locking mechanism 3 automatically locks when the door 4 is closed, such that a hook (not shown) engages a striker (not shown) with the elastic force of a spring (not shown), and
The actuator 8, which will be described later, releases the lock by resisting the force of a spring 411 (not shown) and detaching the hook (not shown) from the striker (not shown). In addition, the loom l has an unlock switch 5 and an unlock request signal transmitter 6.
, a control section 7 , and an actuator 8 .

The unlock switch 5 is provided in a part of the loom 1 including the control panel 2 that is easy for the operator to operate, and is configured, for example, as a self-resetting push button, and is turned on when the operator presses the push button. It looks like this.

The unlocking request signal transmitting unit 6 is composed of the same microcomputer as the control unit 7, and transmits a specific unlocking request signal Q to the control panel 2 by turning on the unlocking switch 5.
The signal is transmitted into the air from a transmitting/receiving antenna 9 such as a loop antenna provided on a loom 1 including a loom.

The control unit 7 is constituted by a microcomputer.
When the transmitting/receiving antenna 9 receives a specific unlocking command signal outputted from an IC card 10 (to be described later), the specific unlocking is performed according to a program stored and set in advance in the memory as a system base by the action of the CPH of the microcomputer. The command signal 1 is compared with the unlock command signal 2 for the loom 1 stored in advance in the memory of the microcomputer, and when these specific unlock command signals and the unlock command signal 2 match, , outputs an actuator operation signal S.

The actuator 8 unlocks the opening mechanism 3 of the loom 1 in response to an actuator operation signal S output from the control section 7.

On the other hand, reference numeral 10 is an IC card that can be carried by a worker such as a service person or maintenance person who adjusts the filler sensitivity and various timing adjustments in each control panel 2+, for example, by putting it in the pocket of a board uniform (possible). It's too big.I
The C card IO has a card body 11 made of synthetic resin, a microcomputer I2, a transmitting/receiving antenna 13, and a backup power supply 14 assembled together.
The second memory contains a program as a system base,
An unlocking request signal Q for each of the plurality of looms 1 and a specific unlocking command signal of 1 for each of the plurality of looms 1 are stored in advance. When the transmitting/receiving antenna 13 receives the lock request signal Q, the microcomputer's CP LJ receives the lock request signal Q according to the program. The specific unlocking lift up strike signal Q1 is compared with a plurality of unlocking request signals Q, and when it matches one of the unlocking request signals Q, the specific unlocking request signal Q is
1 is transmitted into the air from the transmitting/receiving antenna 13 in response to a specific unlocking command signal of the loom I corresponding to 1.

The operation of the above embodiment will be explained based on the flowchart shown in FIG. A worker who wants to adjust the adjustment section in the control panel 2 carries the IC card 1O in the pocket of his outer clothes, goes to the loom 1 that requires adjustment among the plurality of looms 1, and Looms whose working noise requires adjustment
When the unlocking switch 5 is pressed, the unlocking switch 5 is first turned on in step 101, and in step 102, the unlocking request signal transmitter 6 sends a specific unlocking request signal Q corresponding to the loom l that requires adjustment. , is transmitted from the transmitting/receiving antenna 9.

When the transmitting/receiving antenna I3 of the IC card IO carried by the worker receives the transmitted specific unlocking request signal Q as shown in step 103, the IC card IO receives the specific unlocking request signal Q in step 104. The request signal Q is compared with a plurality of unlock request signals Q stored in the memory of the IC card 10, and the specific unlock request signal Q also matches one of the plural unlock request signals Q. If not, the process proceeds to step 105, and if the specific unlock request signal Q1 matches one of the plurality of unlock request signals Q, the process proceeds to step +06.

In step +05, the corresponding unlocking request signal Q is not stored in the memory of the IC card 1o, and the locking mechanism 3 of the control panel 2 is not stored in the IC card IO carried by the worker.
Since it is not desirable to unlock the lock mechanism 3, the process for unlocking the lock mechanism 3 ends. In other words, the lock mechanism 3 is not unlocked.

In step 106, the transmitting/receiving antenna 1 of the IC card IO
1 to a specific unlocking command signal corresponding to the loom 1 that requires adjustment.

Then, this specific unlocking command signal K is sent.

As shown in step 107, when the transmitting/receiving antenna 9 of the loom 1 that requires adjustment receives this, the control unit 7 of the loom I that requires adjustment controls 1 according to the specific unlocking command signal received in step 108. The unlocking command signal of the loom I stored in the memory of the unit 7 is compared with the unlocking command signal of the loom I, and if the specific unlocking command signal does not match with the unlocking command signal stored as 1, step! Proceed to step 09 and receive a specific unlocking command signal K.
.

If it matches the stored unlocking command signal, the process advances to step 110.

In step 109, the corresponding unlocking command signal is not stored in the memory of the control unit 7, and the
Since it is not preferable to unlock the lock mechanism 3 of the control panel 2 in the C card IO, the process for unlocking the lock mechanism 3 ends. In other words, the lock mechanism 3 is not unlocked.

In step 110, the control unit 7 outputs the actuator operation signal S to the actuator 8, and the actuator 8 operates to unlock the lock mechanism 3, so that the hook (not shown) of the lock mechanism 3 is activated by the elastic force of the spring (not shown). It separates from the striker (not shown) against the
The door 4 of the control panel 2 of the loom 1 that requires adjustment is opened, and one cycle of unlocking operation of the loom 1 that requires adjustment is completed.

When the operator closes the door 4 after adjusting the adjustment part in the control panel 2 with the door 4 open, the locking mechanism 3 is not influenced by the actuator 8 but is activated by the elastic force of the spring (not shown). The hook engages with the striker, and the locking mechanism 3 performs a locking operation.

Effects of the Invention As described above, according to the present invention, a worker who carries an IC card that stores unlock request signals applicable to a plurality of looms in advance simply presses the unlock switch of the loom.
The locking mechanism of the loom can be easily unlocked by automatically communicating between the unlocking request signal transmitting unit of the loom whose unlocking switch is pressed, the control unit, and the IC card carried by the worker. . As a result, workers may carry many bulky and heavy key plates on their phones, or find one key plate that corresponds to a particular loom from among the many key plates they carry. It is possible to solve this inconvenience.
