Abstract

PURPOSE:To enhance safety, maintainability and working ability in a power feed device in a pallette transfer machine used in an aging line, by laying a power collector on the lower surface of the pallette in the transferring direction of the pallette, and as well by arranging a plurality of power feeders on a transfer path at intervals of a distance shorter than the length of the collectors. CONSTITUTION:Just after the contact between the conductor 18 of each pallette collector 18 and a contactor 17 of the associated power feeder 13 being made, a proximity switch is actuated by a magnetic member 19 to energize the power feeder 13, and the energization of the power feeder 13 is ceased just before the contactor 17 and the conductor 18 being separated from each other so that electrical spark is prevented from occurring. In this case a moving collector 14 is arranged such that it may be made always in contact with more than one power feeders 13. With this arrangement, safety, maintainability and working ability may be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION Cost and Object of the Invention The present invention relates to a power supply device for supplying power to a pallet moving on a conveyance path.

Conventionally, home appliances and the like are subjected to a series of operational tests after being assembled, and these operational tests are performed on an aging line that is continuous with the assembly line. In other words, this aging line is set up so that various operational tests can be performed while the products are placed on a pallet moving on a conveyor and transported, and the above-mentioned nomilets are equipped with outlets etc. to supply power to the products. ing.

FIGS. 1 and 2 illustrate a conventional Nomilet conveyor and describe its power supply method. In FIG. The figure shows a system in which electric power is supplied to a millet 4 mounted on the conveyor 1 by sliding it on a conductor 3 arranged thereon.

In the device mentioned above, maintenance and inspection are difficult because the chimlet 4 cannot be removed from the conveyor 1, and when the conductor 3 is installed close to the side of the conveyor line, the conductor is exposed. This created a risk of electric shock.

Furthermore, FIG. 2 shows a pallet conveying machine in which a chisel 6 moves on a roller conveyor 5, and since the power supply line 7 is laid along the entire length of the conveyor line, this conveying machine does not allow other equipment to move. 1, or there was a danger that the power supply line 7 could be exposed as in the case shown in FIG. Therefore, in order to avoid this risk, if a configuration is adopted in which the current collector and the insulated conductor slide sideways, it is difficult to maintain good contact between the current collector and the conductor at all times, and it is difficult to obtain the desired contact state. This required a complex configuration.

Furthermore, since home appliances are exported to countries around the world,
The power supply specifications, such as the voltage and frequency used, differed, and several types of power supply were required for the aging line. For this reason, in the case of any of the above power supply methods, it is necessary to install a different aging line for each power supply, or to conduct operation tests for each group of products with the same power supply specifications.
The power supply was switched each time. Therefore, the working efficiency in the aging process was poor.

An object of the present invention is to provide a power supply device that eliminates the drawbacks of the prior art in power supply devices for pallet conveying machines, improves safety and ease of maintenance and inspection, and significantly improves workability in the aging process. There is a particular thing.

Summary of the Invention In other words, the above object of the present invention is to provide a power supply device for a ξlet transporter that has a current collector, allows the ξlet to move along a conveyance path provided with a feeder, It consists of a collector provided extending along the transport path, and a plurality of feeders provided at intervals on the conveyance path, and the interval between the feeders is shorter than the collector length in the conveyance direction, so that the feeder and the collector are Achieved by a power supply device for an e-let carrier, which is characterized in that electricity is applied by contact with electrons.

In addition, the above object of the present invention is to provide a power supply device for a gnolet conveyor in which a gnomelet having a current collector moves on a conveyance path provided with a feeder. The collector and the feeder have a plurality of contacts for supplying power of different specifications, and the distance between the feeder and the collector is shorter than the length of the collector in the transport direction. This is achieved by a power supply device for a pallet conveying machine, which is characterized in that it is energized by contact with the pallet carrier.

EXAMPLE Hereinafter, an example of the implementation of the present invention will be explained in detail with reference to the drawings.

In FIGS. 3 and 4, pallet transport machine 10I'i
, a pallet 12 placed on a roller conveyor 11 is moved in one direction (in the direction of the arrow in the figure) by the drive of the conveyor 11. Further, the power supply device of the pallet conveyor IO includes a plurality of feeders 13 provided at intervals on the conveyance path of the roller conveyor 11, and a collector installed in the lower surface of the nozzle 12 and extending in the conveyance direction. 14 are placed in contact with each other, and the current collector I4 slides on the feeder 13 to feed power to the outlet 15 on the e-let 12. Further, the feeder 13 is connected to the collector 1
A brush-like contactor 17 is provided at a location where the contactor 4 comes into contact with the contactor 4. Furthermore, to explain the relationship between the feeder 13 and the collector 14 with reference to FIG. 6, the distance Lo between the feeder 13 and the collector 14 is
The length in the conveyance direction is set in the relationship Lo<L+, and the current collector 14 on the lower surface of the ξlet 12 is always in contact with one or more feeders 13. The current collector 14 is the fifth one.
As shown in the figure, a metal conductor 18 is attached to the pallet 12 via an insulator 21. However, if the .xi.let 12 is made of an insulator, the metal conductor 18 can also be attached to the pallet 12 as is.

In addition, since the feeder 1-3 needs to be in contact with the collector 14 with a constant pressure, the feeder 13 is provided so as to have an elastic action in the vertical direction, so that the feeder 13 is provided so as to have an elastic action in the vertical direction, even if the moving/ξlet 12 bounces upward. It has a configuration that follows the collector 14 without separating from it.

Next, to explain a preferable example according to the present invention, as shown in FIG. Although the end approach 16 is provided, the contact 1
When contact 7 contacts or separates from the conductor 18 of the current collector 13 in a energized state, an arc is generated between the two, causing melting damage to the contact 17 and the conductor 18. In order to prevent this, a magnetic material 19 (Fig. 4) formed to be slightly shorter than the length of the conductor 18 is placed in the current collector 14 in parallel with the conductor 18 and in the conveying direction, with both ends protruding from the length of the conductor 18. It is installed in an incorrect location.

On the other hand, a detector 20 constituted by a proximity switch is attached to the feeder 13 at a position facing the conductor 18.

The power supply device configured in this manner includes the conductor 18 of the Tsukret current collector being transported and the contact 17 provided on the power supply 13.
Immediately after the contactor 17 and conductor 18 come into contact, a proximity switch is actuated to apply electricity to the feeder 13, and immediately before the contactor 17 and conductor 18 are separated, the application of electricity is stopped to prevent arcing.

In the pallet conveying machine IO equipped with the above-mentioned power supply device, when the Tsukret 12 is placed on the roller bomb pair and is conveyed and mounted on one feeder 13, the end approach 16 of the collector 14 acts suitably and the contact 17 is brought into contact with a conductor 18 which is a live part.

A slight delay after the contact 17 comes into contact with the conductor 18, the feeder 13 is energized, and the outlet 1 on the 12
5. In this manner, power is continuously supplied to the outlet 15 while the feeder 13 and collector 14 continue to be in contact with each other. Then, just before the rear end of the collector 14 passes the feeder 13 with the moving ξlet 12, the power supply to the feeder 13 is stopped, and immediately after that, the collector 14 Separate from 13. On the other hand, since the moving current collector 14 is provided so as to be in constant contact with one or more feeders 13, even if one feeder 13 is separated, the next feeder 13 will newly come into contact with the outlet. 15 is continuously supplied with power.

Furthermore, in the power supply device according to the present invention, different types of power are supplied to the switchboards of the respective feeders 13, and input information such as a magnetic card (not shown) provided in the tuxlet 12 is read on the side of each feeder 13. The power supply can be easily switched based on the input information. In this case, the proximity switch is not required, and this information can also be input into the magnetic card.

By providing the power supply device in this manner, the working efficiency in the aging process can be greatly improved.

Next, another aspect of the present invention will be explained with reference to FIG.
Each of the plurality of feeders 21 provided on the conveyance path has a plurality of contacts 22, and each of the contacts 22 is connected to a power source having a different specification so as to be able to charge power thereto. On the other hand, in the pallet 23, the conductor 18 of the current collector 24 is
provided at a position in contact with any of the elements of 2,
They are configured to collect power supplies with different specifications. It should be noted that each power supply 23 is provided with a different color for each current collecting power source so that identification can be made clearly.

Further, since the constituent elements other than those described above are the same as those described above with reference to FIGS. 3 and 4, explanations thereof will be omitted using the same reference numerals.

When the pallet 23 is transported by the above power supply device,
The detector 20 detects the magnetic body 19 and charges the feeder 21 with electricity. At this time, the collector 24 contacts only the predetermined contacts 22 and can supply only the intended power to the outlet. Therefore, even if pallets 23 with different current collection power supplies are transported randomly, each Nomilet 23 collects only a predetermined power supply, eliminating the trouble of switching power supplies, etc.; By clearly displaying the power source, there is no misidentification of usage, and it is possible to significantly improve work.

Effects of the Invention As described above, according to the power supply device according to the present invention, the pallet moving on the roller conveyor can be easily removed by simply being placed on the conveyor, and the power supply is also exposed. , maintenance and inspection can be done easily. Further, since the feeder is energized only when it is located under the pallet, there is no risk of electric shock.
