Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device that is capable of automatically branching a conveying moving body to a station line branched from a main line according to a preset destination.

In this type of conveyance device, when a station line is fully loaded with a predetermined number of conveyance vehicles, even if a conveyance vehicle whose destination is this station line moves, the station line is The main line is circulated without branching into the station line, but in this type of control method, workers belonging to the station line are required to move the main line to the main line without entering the station line. Since there is no way of knowing that the line is being circulated, the work must be carried out regardless of this fact, which not only reduces the efficiency of using the conveying body, but also causes wasteful use of the conveying body on the main line. As the number of trips increases, the economic efficiency also decreases.

The present invention provides a conveyance device that is useful for solving the above-mentioned disadvantages, and one embodiment thereof will be described below based on illustrative drawings.

In FIG. 1, reference numeral 1 denotes a self-propelled container for transportation, which is equipped with guide wheels that fit into a pair of left and right guide rails 2, and a propulsion drive means driven by electric power supplied from a pair of power supply rails 3. Built-in.

4 is a destination setting means attached to the side of the container 1;
It is of a type in which a plurality of magnets 5 are set at positions corresponding to destination codes.

Reference numeral 6 denotes a signal exchange rail for transmitting control signals to and from the travel control means built into the container 1, and is provided in parallel to the power supply rail 3.

In FIG. 2, 7 is a main line on which the container 1 can circulate, and 8 is a route switching means 9 from the main line 7.
10 is a storage line connected to the main line 7 by route switching means 11, 12, and is provided with a transverse rail 13 for container transfer at the folded end.

As shown in FIG. 3, on the station line 8, rails 6a to 6c for detecting the presence of each container 1 to be stopped are laid as many as the permissible number of storage units (three in the illustrated example). A full capacity detection means 16 is constituted by an AND circuit 15 which outputs a full capacity detection signal 14 when the presence detection signals are inputted from all of the seats 6a to 6c.

Further, the route switching means 9 at the branch point between the main line 7 and the station line 8 is provided with a lateral movement rail 17 that moves laterally between a position where it connects to the main line 7 and a position where it connects to the station 8. , this lateral movement rail 17
is provided with destination reading means 18 set in the destination setting means 4 of the container 1.

The code read from the destination reading means 18 is compared with the setting code corresponding to the station line 8 to which it belongs in the comparison circuit 19, and if they match, a branching command signal 21 is outputted to the container branching control means 20.

This container branching control means 20 controls the signal sending/receiving rail 6 installed on the lateral movement rail 17 based on the branching command signal 21.
A stop command is given to the container 1 on the lateral movement rail 17 through the rail 6d, the lateral movement rail 17 is laterally moved to a position where it is connected to the station line 8, and then a forward command is given to the container 1 through the rail 6d. .

The branch command signal 21 is transmitted to the transmission system of the branch command signal 21 by the full quantity detection signal 14 from the full quantity detection means 16.
A gate circuit 22 is provided for canceling out.

A that outputs an alarm command signal 24 to the alarm means 23 when the branch command signal 21 and the full quantity detection signal 14 are input.
An ND circuit 25 is provided.

The alarm means 23 includes a buzzer, a bell, a red lamp, etc. arranged near the station line 8.

Incidentally, the destination reading means 18 may be provided beside the main line in front of the route switching means 9.

Next, to explain the operation, the container 1 launched from the station line 8 to the other station line 8 is moved to the main line 7 by the route switching means 9 at each branch point.
When passing over the lateral movement rail 17 in , the destination code set in the destination setting means 4 is read by the destination reading means 18, and if it does not match the set code, the branch point is passed, and if it matches, the comparison circuit 19 Branch command signal 2 from
1 is output.

At this time, if the station line 8 branched from this branch point is not full, the full detection signal 14 is not output, so the branch command signal 21 is input to the branch control means 20 without being canceled in the gate circuit 22. Then, this branch control circuit 20 is operated, and the container 1 is guided to the target station line 8 by the lateral movement rail 17 as described above, travels along this station line 8, and stops at a predetermined position at the terminal end.

If three containers 1 are already stored in the station line 8, each presence detection rail 6a to 6c
If the presence detection signal is input to the AND circuit 15 from Since no input is made to the control means 20, the container 1 passes through the branch point as it is.

At the same time, the full quantity detection signal 14 and the branch command signal 21 are input to the AND circuit 25, so the alarm command signal 2
4 is output and the alarm means 23 is activated.

In the above embodiment, the full capacity detection means composed of the presence detection rails 6a to 6c and the AND circuit 15 is used as the full capacity detection means, but the present invention is not limited to this. Any configuration may be used as long as it is capable of detecting whether or not the number of movable bodies is equal to the preset full capacity.

Further, although the destination reading means 18 as a destination detection means is provided on the lateral movement rail 17 of the route switching means 9, the destination reading means 18 may be disposed on the side of the route before the route switching means 9, as is conventionally known. You can also do it.

Furthermore, the track switching means 9 is not limited to the type using the lateral movement rail 17.

The conveying device of the present invention can be implemented and used as in the above embodiment, and its characteristics include a station line branched from the main line via a route switching means, and a conveying device located on this station line. Full quantity detection means for detecting whether the number of movable bodies is a preset number equivalent to full capacity, and destination detection means for detecting whether the conveying movable body is to be branched to the station line. , alarm means, and control device (comparison circuit 19 in the embodiment)
, a branch control means 20, a gate circuit 22, an AND circuit 25, etc.), and the control device includes:
Only when the full quantity detection means is not outputting a full quantity detection signal and the destination detection means detects a conveyance moving body whose destination is the station line, the conveyance movable body is moved to the station line. The destination detecting means detects a conveyance moving body whose destination is the station line while the route switching means is activated to branch and the full quantity detecting means is outputting a full quantity detection signal. In some cases, the alarm means is configured to be activated.

According to such a configuration of the present invention, the effects described below with the reference numerals of the embodiments described above can be obtained.

Immediately, if the station line 8 is full and cannot accept any more containers 1, the containers 1 whose destination is this station line 8 will not branch into the station line 8. The container 1 can be passed through and circulated on the main line 7, but on the station line 8, the container 1 whose destination is this station line 8
The alarm means 23 can immediately notify the assigned workers that the machine is on standby in the main line 7.

Therefore, the worker promptly carries out the work of returning the container 1 stored in this station line 8 to another station line 8 to which it belongs or the work of sending it to the storage line 10, so that this station line 8 has a vacant seat. By erasing the full quantity detection signal 14, the container 1 which is waiting and moving on the main line 7 can be immediately branched into the station line 8.

By prompting the workers to perform the necessary work in this way, it is possible to minimize unnecessary travel while waiting for a vacant seat for the container 1 on the main line 7, thereby increasing economic efficiency and increasing the efficiency of use of the container 1. can.

Although the container 1 is illustrated as an example of a moving body for transportation, any other type may be used.

In addition, in FIG. 2, the same guide rail and the same running route switching means 9 are used.
Although the station line 8 is shown as a type that sends the container 1 to the main line 7 using a station line 8, it may be of the same type as the storage line 10.
