Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a hoisting device for hoisting a signal flag used as a means of transmitting information on a ship or the like.

[Prior art]

Conventionally, this type of hoisting device consists of a pulley attached to the upper end of a mast, etc., and a rope hung on the pulley, and a signal flag is attached to the rope by a human hand and the rope is pulled. The one that is hoisted is generally known.

[Problems to be solved by this idea]

However, when displaying signal flags in response to the need to convey information, a person selects the signal flags necessary to represent the content, carries them from the storage location to the mast, and then attaches them to a rope and pulls them. This required laborious work.

Furthermore, when attaching a signal flag to a rope, since the signal flag is usually made of cloth, a time-consuming work is required to secure the hook attached to the signal flag to the hook attached to the rope.

Furthermore, depending on the wind conditions, there were problems such as signal flags getting tangled with ropes and making the contents of the signals difficult to read.

This idea was devised in view of the above-mentioned circumstances, and its purpose is to provide an automatic hoisting device that can easily and quickly hoist signal flags without manual effort, and that can reliably transmit information. It is in.

According to this invention, the signal flag is formed from a panel, and is automatically raised by a hoisting device without the need for human hands.

This hoisting device includes a storage section in which a plurality of signal flag panels of different types are stored, an ejection section that takes out the signal flag panels from the storage section, and a hoisting section that hoists the signal flag panels taken out from the ejection section. , and a control section that controls the movement of each of these sections to display a predetermined signal flag panel.

By inputting a hoisting signal to the control section, a signal flag capable of transmitting predetermined information is automatically hoisted.

〔Example〕

This invention will be explained below with reference to illustrated embodiments.

The automatic hoisting device 1 includes a storage section 2 in which a plurality of signal flag panels 4 of different types are stored, a take-out section 5 that takes out one signal flag panel 4 from the storage section 2, and a signal flag taken out by the take-out section 5. It consists of a hoisting section 6 that hoists the panel 4, and a control section 7 that controls the movement of these sections to hoist a predetermined signal flag panel 4. (See Figure 1).

The storage section 2 is formed into a box having a rectangular cross-sectional shape in which a rectangular signal flag panel can be stored. One side 2a is open so that the signal flag panel 4 can enter and exit, and the other side 2b is provided with an opening 3 through which a pressing part 9 provided at the tip of the rod of an air cylinder 8, which will be described later, can pass. It is being

In addition, a through hole 1 for an extraction sensor 10, which will be described later, is provided on the top surface.
1, and on the underside there is a rack 1 fixed on the hull.
2 are provided with gears 13 that mesh with each other and move the storage section 2 back and forth by an electric motor or the like, and fixing grooves 14 for fixing the signal flag panel 4 are provided on the upper and lower surfaces of the interior (the first Figure, 2nd
(see figure).

The take-out section 5 includes an air cylinder 8 that pushes out the signal flag panel 4 from the storage section 2 to the hoisting section 6, and an air cylinder 8' that pushes out the signal flag panel 4 from the hoisting section 6 to the hoisting section 2.

The hoisting section 6 is formed in a ladder shape from left and right vertical frames 15 and a plurality of horizontal frames 16 provided between the vertical frames 15, and each horizontal frame 16 has a signal flag panel 4 on its opposing surface. A fixing groove 17 for fixing is provided.

The signal flag panel 4 is configured to be inserted and fixed between the left and right vertical frames 15 and the top and bottom horizontal frames 16 by using a fixing groove 17.
A rack 18 provided on the vertical frame 15,
The pinion 19 and the electric motor 20 are configured to allow vertical movement.

The fixing grooves 17 and 14 between the hoisting section horizontal frame 16 and the inside of the storage section 2 mentioned above have predetermined grooves that protrude into the grooves at the ends on the storage section 2 side and the ends on the hoisting section 6 side. A stopper 21 for the signal flag panel 4 is provided, which is configured to retract when a greater force is applied.

The control unit 7 includes a signal flag extraction sensor 10 such as a barcode read, a magnetic sensor, an optical sensor, etc. provided on the top surface of the storage unit 2, and various regulations such as the International Signal Book that are stored and should be transmitted. An information processing section 22 that determines the necessary signal flag panel 4 when information is input, and a control section 23 that controls the operation of the gear 13 of the storage section 2, the air cylinder 8, and the electric motor 20.
It is made up of.

In hoisting the signal flag panel 4 by the automatic hoisting device 1 having such a configuration, information to be transmitted is first input to the information processing section 22 of the control section 7, as shown in FIGS. 1 to 3.

Next, the information processing section 22 determines the type and number of signal flags corresponding to the input information, sends an activation signal to the signal flag extraction sensor 10, and sends an input information signal to the control section 23.

Next, the control section 23 sends an activation signal to the gear 13 to operate it and move the storage section 2 so that the readout signal from the signal flag extraction sensor 10 and the input information signal from the information processing section 22 match. When the readout signal and the input information signal match, the movement of the storage section 2 is stopped at the panel removal position.

Next, when a confirmation signal is sent to the information processing unit 22 and the confirmation is confirmed, an activation signal is sent to the air cylinder 8 of the take-out unit 5 to activate it, and the signal flag panel 4 is pressed by the pressing unit 9 to the left and right vertical frames 15 of the hoisting unit 6. and the upper and lower horizontal frames 16.

When the signal flag panel 4 is inserted and fixed into the hoisting section 6, the control section 7 sends an activation signal to the electric motor 20 to activate it and move the hoisting section 6 upward.

In this way, the signal flag panel 4 representing the information to be transmitted is automatically raised.

When lowering the signal flag panel 4, conversely, stop the fixed part of the signal flag panel 4 in the hoisting part 6 at the storage part 2 position, take it out from the hoisting part 6 by the pressing part 9 of the air cylinder 8', and lower it into the storage part 2. Insert and secure. At this time, the storage section 2 is detected by the extraction sensor 10 and is placed in the position of the fixing groove 14 where the signal flag panel 4 is not fixed.

FIG. 4 shows another embodiment of the automatic hoisting device of this invention. In this case, the fixation of the signal flag panel 4 to the hoisting part 6 and the removal part 5 are made the same.

That is, the horizontal frame in the hoisting section 6 is eliminated, and
A storage section 2 is arranged between both vertical frames 15. The signal flag panel 4 is taken out from the storage section 2 and fixed to both vertical frames 15 using the vertical frame 15.
This is done using both electromagnets 24, 24' which are provided at the same distance as the height of the signal flag panel 4.

Therefore, first, when taking out the signal flag panel 4, the electromagnet 24 of the vertical frame 15 is aligned with the upper end position of the signal flag panel 4. Then, the electromagnet 24 is magnetized to generate a magnetic force to attract the upper end of the signal flag panel 4, and in this state, the vertical frame 15 is moved upward to take out the signal flag panel 4 from the storage section 2.

Next, when the lower end of the signal flag panel 4 comes out of the storage section 2, the electromagnet 24 is magnetized and attracted.
To securely fix a signal flag panel 4. In this state, the signal flag panel 4 is hoisted by moving the vertical frame 15 upward.

Next, when lowering the signal flag panel 4, first move the vertical frame 15 downward. When the signal flag panel 4 comes directly above the storage section 2, the electromagnet 24' is demagnetized and the signal flag panel 4 is inserted into the storage section 2. Thereafter, the electromagnet 24 is demagnetized and the signal flag panel 4 is removed from the vertical frame 15.

In addition, at both ends of the upper part of the signal flag panel 4 in this embodiment, adsorption protrusions 25 are provided that protrude toward the electromagnet 24 side (vertical frame 15 side) so that the adsorption by the electromagnet 24 is ensured. .

Further, the operation of the storage section 2 and the vertical frame 15 and the extraction of the signal flag panel 4, including the extraction operation using an electromagnet, are performed by the control section 7 in the same manner as in the embodiment shown in FIG. 1 described above.

Furthermore, the shape and configuration of the storage section, take-out section, and hoisting section in the automatic hoisting device of this invention are as described above.
The present invention is not limited to those of the above embodiments, but any type of flag panel may be used as long as it can select and display a signal flag panel representing the information to be transmitted.

[Effects of the invention] This invention has the structure described above and has the following effects.

By automatically controlling the control unit to take out and display a signal flag panel from a storage unit in which a plurality of signal flag panels of different types are stored, a predetermined signal flag panel representing the information to be transmitted can be displayed. can be done automatically.

Therefore, the selection of signal flags, which was previously done by humans,
By being able to carry out all operations such as transportation, hoisting, and storage automatically, it becomes possible to quickly transmit information.

Additionally, the means of transmitting information through signal flags can be unmanned, resulting in significant labor savings.

Furthermore, with conventional cloth signal flags, it may be impossible to display signals depending on the weather, but by making the signal flags into panels that do not deform, it is now possible to display them regardless of the weather.
