Description

[Detailed description of the invention] Industrial field of application The present invention relates to a power supply device used in transportation equipment installed in a factory and used to transport loads (articles) between work sites, for example. It is.

BACKGROUND ART Conventionally, as a power supply device for this type of equipment, configurations such as those shown in, for example, Japanese Patent Laid-Open No. 61-6063 and Japanese Patent Laid-Open No. 59-160657 have been provided. In other words, conventionally, a power supply rail and a guide rail are arranged in parallel, and a movable body supported and guided by the guide rail via wheels or the like can travel on a fixed path, and a current collector is attached to this movable body. It is set up.

According to this conventional configuration, the current collector of the current collector is brought into sliding contact with the power supply rail to collect current, which drives the motor mounted on the movable body to rotate the pinion and main wheel, thereby keeping the movable body constant. It is running on the route.

Problems to be Solved by the Invention According to the conventional type as described above, the current collector gradually wears out as it is used, and when it wears out beyond a certain amount, poor contact occurs and current collection becomes impossible. If such a situation occurs during transportation, the movable body will stop at an unspecified location on the fixed route, making it difficult to repair and also stopping the operation of the entire equipment.

In order to avoid such a situation, it is conceivable to take the movable body out onto an inspection path that branches off from the fixed path, perform wear inspection and repair on this inspection path, and then merge the movable body into the fixed path.
However, according to this method, all movable bodies, including movable bodies whose collectors are barely worn out, are subject to periodic inspection, and the inspection process takes a considerable amount of time.

The purpose of the present invention is to provide a power supply device for conveyance equipment that can constantly perform wear inspections at specific locations along a certain route and automatically detect movable bodies that have collectors that have a large amount of wear. be.

Means for Solving the Problems In order to solve the above-mentioned problems, the power supply device for transport equipment of the present invention is a power supply device for transport equipment that has a power supply rail 25 and an inspection rail 64. The rail 64 is an inspection rail 64.
has a protruding piece 62 of a predetermined length and is inserted into the power supply rail 25 and arranged along the guide rail 1, on which the movable body 4 constituting the conveyance equipment is disposed. A current collector 32 is attached to the movable body 4, the base end of which is held by a current collector holding member 31, and the tip of which is biased to protrude outward. It collects current by slidingly contacting the rail 25 and the inspection rail 64, and depending on whether the tip of the protruding piece 62 of the inspection rail 64 touches the current collector holding member 31,
The collector 32 is being inspected for wear.

Effects According to the configuration of the present invention, the current collector is brought into sliding contact with the power supply rail to collect current, thereby making it possible for the movable body to run on the guide rail. The movable body then enters the inspection rail section, and the wear state of the current collector is inspected. In other words, when the collector has a lot of wear and its length is short, the collector holding member on the collector side, which is urged to protrude outward, comes into contact with the protruding piece and is prevented from protruding any further. The current collector does not make contact with the rail or has poor contact. As a result, it is detected that the current collector is worn out more than necessary and is defective. Then, the movable body detected as defective is moved from a fixed path to a repair path at that location or another location, and then the current collector is repaired.

and a spring 33 provided between.

Note that the upper surface of the main body of the movable body 4 is formed, for example, as a loading surface 34.

As shown in FIGS. 1 to 3 and 6, an inspection section 41 having a collector inspection device 40 is provided at a set location in the fixed path 5. As shown in FIGS. In this inspection section 41, the guide rail 1 is formed into divided rails 42 divided into sections of a predetermined length, and the cover 19 is also formed into divided covers 43 accordingly. Two floor rails 44 extending in a direction perpendicular to the constant path 5 are laid via a base frame 50, and a movable frame 46 supported and guided via wheels 45 is provided on these floor rails 44. The dividing rail 42 and the like are fixed to the upper surface of one side of the movable frame 46 via a support 47. A relay rail 48 parallel to the dividing rail 42 is disposed on the upper surface of the other side of the movable frame 46, and this relay rail 48 also has a relay cover 49 and the like. Therefore, by moving the movable frame 46, the dividing rail 42 and the relay rail 48 can be selectively connected to the guide rail 1. A drive device 51 for moving the movable frame 46
comprises a rack rail 52 attached to the base frame 50 parallel to the floor rail 44, a motor 53 attached to the movable frame 46, and a rack attached to the deceleration output shaft of the motor 53 and meshed with the rack part of the rack rail 52. It consists of a gear (pinion) 54. Reference numerals 55 and 56 indicate stoppers for receiving the movable frame 46.

The current collector inspection device 40 has the same structure as the power supply device 20, and includes a divided strip 60, a divided spacer 61, a channel-shaped protruding piece 62 that is open on the inside, and has a channel-shaped protruding piece 62 at the innermost part of the protruding piece 62. An inspection rail 64 connected to an inspection machine 63 is provided. This inspection rail 64 is inserted into the divided portion of the power supply rail 25 . Furthermore, the lateral length L of the protruding piece 62 is determined by
It is set to a predetermined length such that the inward end thereof protrudes inward by _a predetermined length _l2 .

Parallel to the constant path 5, the dividing rail 4
A standby route 65 for a preliminary movable body to which one end of 2 can be freely connected.
and a defective movable body extraction route 6 whose other end can be freely connected.
6 is formed.

Next, the operation of the above embodiment will be explained.

The movable body 4 is connected to a pinion 15 by a traveling drive device 12.
By rotating it, it is supported and guided by the guide rail 1 and travels on a fixed route 5. At this time, the wheels 8 are supported and guided on the upper surface of the plate body 1B, the floating prevention rollers 9 are guided on the lower surface of the plate body 1B, and the lateral slip prevention rollers 10 are supported on the pipe body 1B.
Since the movable body 4 is guided by both sides of A, the movable body 4 can travel stably. During such traveling, each collector 32 comes into sliding contact with the power supply rail 25 as shown in FIG. 5, and performs the desired current collection. At this time, the link support member 29 moves up and down against the buffer spring 28, so that the vertical displacement can be absorbed. The power supply rail 25 is pressed and biased via the power supply rail 25.

Normally, in the inspection section 41, as shown in FIGS. 1 and 2, the dividing rail 42 is connected to the guide rail 1, and the spare movable body 4 is waiting on the relay rail 48. In this state, the movable body 4 that has traveled on the fixed path 5 transfers from the guide rail 1 to the dividing rail 42, stops within this dividing rail 42, or is inspected by the inspection device 40 while traveling on the dividing rail 42. Then, the collector 32 is inspected for wear.

This wear inspection is performed using a predetermined lateral length L.
The basis is whether the current collector holding member 31 touches the tip (inward end) of the protruding piece 62. That is, when the collector 32 has little wear, the collector 32 itself is long, so the collector holding member 31 does not come into contact with the tip of the protruding piece 62, and therefore the collector 32 does not touch the inspection rail 64. If the contact is in good condition, the test is passed. As a result, the movable body 4 transfers from the dividing rail 42 to the guide rail 1 again and performs the intended work travel. In addition, when the collector 32 has a lot of wear and its length is short, as shown in FIG. 6A, the protruding piece 62
The current collector holding member 31 comes into contact with the tip of the current collector 32 and rides on it, and as a result, the current collector 32 does not come into contact with the inspection rail 64, or a contact failure (current failure) occurs, and a defect is detected.

Based on this inspection result, an instruction is issued, for example, by an alarm, and the drive device 51 is activated to move the movable frame 46 to one side. As a result, the dividing rail 42 is connected to the standby path 65 and the extraction path 66, and the relay rail 48 is connected to the guide rail 1. Therefore, the spare movable body 4 on the relay rail 48 can be put into the fixed path 5, and the defective movable body 4 on the dividing rail 42 can be extracted to the extraction path 66 for repair.

In the above embodiment, the inspection shows that the current collector 32
When there is little wear, the movable body 4 can transfer from the dividing rail 42 to the guide rail 1 and run on the fixed path 5 again. In addition, when the collector 32 has a lot of wear, the dividing rail 4
2 is removed from the guide rail 1, the intermediate rail 48 can be inserted into the trace and connected to the guide rail 1, and therefore the intermediate rail 4 can be connected to the guide rail 1.
The spare movable body 4 kept on standby at 8 can be thrown into the fixed route 5 without interfering with the intended work, and the subsequent movable body 4 can be run on the fixed route 5 via the relay rail 48. I can do it. The movable body 5 on the dividing rail 42 can then be moved to a repair path or the like to repair the current collector.

In addition, in the present invention, a type without the dividing rail 42 or relay rail 48 is also possible, and in this case, the defective movable body 4 is branched to a repair path provided downstream via a branching device, and After repair, it merges into the fixed route 5.

Note that the inspection rail 64 can also serve as the power supply rail 25.

Effects of the Invention According to the present invention having the above configuration, the movable body can be made to run on the guide rail by bringing the current collector into sliding contact with the power supply rail to collect current. The movable body then enters the inspection rail section, where the wear state of the current collector can be inspected. That is, when the collector has a lot of wear and its length is short, the collector holding member on the collector side that is urged to protrude outward comes into contact with the protruding piece and cannot prevent further protrusion. , this will cause the current collector to have no contact or poor contact with the inspection rail.
It is possible to detect that the current collector is worn out more than necessary and is defective.

In this way, according to the present invention, wear inspection can always be automatically performed at a specific location on a certain path, and a movable body having a current collector with a large amount of wear can be inspected at this specific location or at another location. It can be removed from a fixed route at any location, and inspections and repairs can be carried out efficiently without stopping the entire operation.
