Abstract

PURPOSE:To prevent overload by installing an object receptacle table at a gateway through which object is loaded on a dumbwaiter cage, sensing the weight of the object placed on the table, and issuing alarm when the sensed weight exceeds the allowable value. CONSTITUTION:When an object N is loaded on a dumbwaiter cage 5, the object N is placed on an object receptacle table 1 installed at a gateway 12. When at this time the weight of the object N exceeds the allowable value, the subsidence of the receptacle table 1 exceeds the tolerance. This causes a switch 1b to be actuated to notify that an overload has occurred. This allows a control device 7 in a machine room 6 to actuate a voice synthesizing device 7a, from which an acoustic alarm of overload is given to the operator and also transmitted to a speaker 8 mounted on a gateway frame 3. With this alarm, the operator can find that the object placed on the receptacle table 1 is over the weight limitation.

When loading the luggage N on the car 5, first,
The luggage N is placed on the loading / unloading port cradle 1 installed in the loading / unloading port 12.

At this time, the loading / unloading port cradle 1 sinks downward against the elastic supporting force of the spring 1a due to the weight of the load N. The amount of this subsidence naturally depends on the weight of the luggage N.

Here, when the weight of the load N is 50 kg or less which is a loadable amount, the sinking amount of the loading / unloading port cradle 1 is naturally less than the allowable amount and the switch 1b does not operate. In this case, since the control device 7 does not detect the operation of the switch 1b, the speaker 8 gives no warning. Therefore, the operator moves the luggage N into the car 5 by opening the access door 4 and the access door 4a while the car 5 is on the floor.

On the other hand, when the weight of the baggage N exceeds the loadable capacity, for example, 60 kg, as shown in the schematic diagram of FIG. 2, the sinking amount of the loading / unloading port pedestal 1 is: Exceeds the allowable amount.

As a result, the switch 1b operates to detect overload. The operation of the switch 1b is transmitted to the control device 7 in the machine room 6. In response to this, the control device 7 causes the voice synthesizing device 7a to generate an overload warning voice to the operator, for example, a message "overweight", and the speaker 8 attached to the access slot 3 of the access slot 12. Tell.

The operator can know from the warning sound from the speaker 8 that the load N placed on the loading / unloading port pedestal 1 is overweight.

That is, according to the first embodiment, when the operator tries to put the luggage N on the car 5, the weight of the luggage N becomes the loadable weight when the luggage N is placed on the loading / unloading port cradle 1. It detects whether it is within the range or overweight. In the case of overloading, the operator is alerted to this by voice, so that the operator can know that the weight N is overweight before placing the load N on the car 5. As a result, it is possible to reduce the weight of the load N to a loadable weight and load it, or select another transportation means.
It is possible to prevent a failure or accident of the dam waiter device.

Example 2. FIG. 3 is a schematic configuration diagram of a dam weight device according to a second embodiment of the present invention. In the figure, reference numeral 9 is an electromagnetic lock device controlled by the control device 7, and operates the plunger 9a to prohibit the upper door 4 and the lower door 4a of the entrance / exit from opening. When the load N is placed on the loading / unloading port pedestal 1 and is overloaded, the switch 1b detects this and transmits it to the control device 7 in the machine room 6 in the same configuration as in FIG. is there.

Next, the operation of the above-described structure will be described.

When loading the luggage N on the car 5, first,
The load N is placed on the loading / unloading port cradle 1 installed in the loading / unloading port 12, but when the weight exceeds a loadable capacity, for example, 60 kg, the loading / unloading port cradle 1 is Sink beyond capacity.

As a result, the switch 1b operates to detect overload. The operation of the switch 1b is transmitted to the control device 7 in the machine room 6. In response to this, the control device 7 operates the electromagnetic lock device 9. As a result, the plunger 9
a pops out and the upper door 4 and the lower door 4
Lock a in the closed position. That is, the upper door 4 of the access port and the lower door 4a of the access port cannot be opened.

Therefore, the operator cannot place the luggage N placed on the loading / unloading port cradle 1 on the car 5.

That is, according to the second embodiment, when the operator tries to put the luggage N on the car 5, the weight of the luggage N becomes the loadable weight when the luggage N is placed on the loading / unloading port cradle 1. It detects whether it is within the range or overweight. Then, in the case of overloading, the upper door 4 and the lower door 4a of the loading / unloading port are prevented from opening, so that the operator
The luggage N cannot be placed on the car 5. The upper door 4 and the lower door 4a of the loading / unloading opening cannot be opened unless the weight of the luggage N is reduced to the loadable weight and the loading is performed again.
It is possible to prevent a failure or accident from occurring by operating the dam waiter device while overloaded.

Example 3. FIG. 4 is a schematic configuration diagram of a dam weight device according to a third embodiment of the present invention. In the figure, 10
Is a visual display device that is controlled to blink by the control device 7, and, for example, at the access port 12, for example, the access port frame 3
A visual warning such as "Overweight" is displayed above. When a baggage N is placed on the loading / unloading port cradle 1,
When this is overloaded, the configuration for detecting it by the switch 1b and transmitting it to the control device 7 in the machine room 6 is the same as the configuration in FIG.

Next, the operation of the above-described structure will be described.

When loading the luggage N on the car 5, first,
The baggage N is placed on the loading / unloading port cradle 1 installed in the loading / unloading port 12. At this time, if the weight of the package N exceeds the load capacity, the loading / unloading port cradle 1 exceeds the allowable amount. And sink.

As a result, the switch 1b operates to detect overload. The operation of the switch 1b is transmitted to the control device 7 in the machine room 6. In response to this, the control device 7 turns on the visual display device 10.

The operator can know that the load N placed on the loading / unloading port cradle 1 is overweight by a visual warning display such as "overweight" displayed on the visual display device 10. it can.

That is, according to the third embodiment, when the operator tries to put the load N on the car 5, the weight of the load N becomes the loadable weight when the load N is placed on the loading / unloading port cradle 1. It detects whether it is in the range or overweight. Then, in the case of overloading, the operator is warned by the warning display of the visual display device 10, so that the operator can know that the weight N is overweight before placing the load N on the car 5. As a result, it is possible to take measures such as reducing the weight of the load N to a loadable weight and reloading the load N, selecting another transporting means, etc., and preventing a failure or accident of the dam waiter device. .

In this embodiment, the warning display of the visual display device 10 may be a blinking display instead of continuous lighting in order to call the operator's attention. In addition, a warning sound such as a buzzer may be output at the same time.

Example 4. FIG. 5 is a schematic configuration diagram of a dam weight device according to a fourth embodiment of the present invention. In the figure, 1c
Is, when a baggage N is placed on the loading / unloading port cradle 1,
This is a call registration switch for detecting this. The call registration switch 1c operates by sinking of the loading / unloading port pedestal 1 when, for example, a load N of 100 g or more is placed on the loading / unloading port pedestal 1. Also, 1
Reference numeral 1 denotes a push-in / push-out push button mounted on the take-in / out port frame 3 at the take-in / out port 12, which is used for call registration.

The operation of the above-described structure will be described below with reference to the flowchart of FIG.

Now, the loadable weight of the car 5 is 50 kg, and the switch 1b is the load N placed on the loading / unloading port cradle 1.
Shall operate when the weight exceeds 50 kg.

When the load N is not placed on the loading / unloading port pedestal 1, the loading / unloading port pedestal 1 does not sink at all, and the call registration switch 1c does not operate. Therefore, the control device 7 repeats the control routine of step S1 and waits for the operation of the call registration switch 1c.

Next, a case where a load N having a weight of 5 kg is loaded on the car 5 will be described.

When trying to load the luggage N on the car 5,
First, the loading / unloading port cradle 1 installed in the loading / unloading port 12.
Place luggage N on top.

At this time, the loading / unloading port cradle 1 sinks downward against the elastic supporting force of the spring 1a due to the weight of the load N. Since the weight of the luggage N is 5 kg, which is 100 grams or more of the luggage detection limit, and the loadable weight is 50 kg or less, the sinking amount is such that the call registration switch 1c is operated and the switch 1b is not operated. It is a thing.

Since the control device 7 detects the operation of the call registration switch 1c in step S1 and detects that the switch 1b is not operating in step S2, it enters the control of step S3.

In step S3, the controller 7 causes the car 5
Determines whether the car is on the floor, and if the car 5 is on the floor, the process directly returns to step S1.
Is not on the floor, the process moves to step S4 to register the call on the floor.

In other words, normally, the operator registers the call of the car 5 with respect to the floor by pushing the push-in / push-out push button 11, but the call registration is automatically performed only by placing the load N on the load / unload gate 1. Therefore, the operator can save the trouble of pushing the push-in / push-out push button 11. This function is very effective in a situation where the operator holds the luggage N with both hands and cannot press the access port push button 11.

Next, the baggage N having a weight of 60 kg is loaded into the car 5
The operation when loading is attempted, that is, the operation when there is a risk of overloading will be described.

When trying to load the luggage N on the car 5,
First, the loading / unloading port cradle 1 installed in the loading / unloading port 12.
Place luggage N on top.

At this time, the loading / unloading port cradle 1 sinks downward against the elastic supporting force of the spring 1a due to the weight of the load N. Since the weight of the cargo N is 60 kg, which is 100 grams or more, which is the limit of luggage detection, and 50 kg or more of the loadable weight, the sinking amount is 50 kg or more, so both the call registration switch 1c and the switch 1b are operated.

Since the control device 7 detects the operation of the call registration switch 1c in step S1 and the operation of the switch 1b in step S2, the control device 7 enters the control of step S5.

In step S5, the control device 7 detects overloading through the operation of the switch 1b, and the voice synthesizer 7
In a, an overload warning voice to the operator, for example,
A message of "overweight" is generated, and it is transmitted to the speaker 8 attached to the inlet / outlet frame 3 of the inlet / outlet 12 for automatic announcement.

This automatic announcement prompts the operator to reduce the weight of the load N on the loading / unloading port cradle 1.

In this case, of course, the call of the car 5 for the floor is not registered.

The operator can know from the alarm sound from the speaker 8 that the load N placed on the loading / unloading port pedestal 1 is overweight, and the weight of the load N is reduced to a loadable weight and placed. It is possible to take measures such as changing back or selecting other transportation means, and it is possible to prevent a failure or accident of the dam waiter device. Further, since no call registration is performed, it is possible to reduce the risk that the luggage N is accidentally loaded on the car 5 despite the warning sound.

Although each of the above-described embodiments has been described by taking only one of the many floors as an example, a similar entrance / exit 12 is installed in each floor and is controlled by the control device 7 as a whole. It goes without saying that it will be done.

In each of the above-described embodiments, the weight of the load N placed on the loading / unloading port cradle 1 is exceeded by the spring 1a.
Switch the amount of sinking of the loading / unloading platform 1 on the switch 1
Although the configuration for detecting with b is illustrated, other detecting means,
For example, a tension sensor or a detector using light can be applied.

On the other hand, it is of course possible to take multiple measures against overloading, such as voice warning, visual warning, warning sound such as buzzer, door lock, call prohibition, etc. The risk of loading can be greatly reduced.

[0064]

As described above, the dam waiter apparatus according to the present invention, when loading a load on the dam waiter car, confirms that the weight of the load is within the loadable weight before the actual loading. Since it is configured to detect an overload and take a warning, prohibit loading, or the like, it is possible to prevent overloading on the dam waiter car and prevent failures or accidents.
