Abstract

PURPOSE:To make handling easy by an apparatus which comprises a pallet conveying path, a pair of feeding rails having paired feeding lines disposed on the pallet conveying path, a current collecting pallet movably mounted on the pallet conveying path. CONSTITUTION:At an upper intermediate position of a pallet conveying path 12 constituted by a roller conveyor 11, a pair of feeding rails 15, 15 provided with feeding conductors 13, 13 supported by insulating materials 14, 14 are arranged in parallel to extend in the conveyance direction, those feeding conductors 13, 13 being faced each other. A current collecting pallet 16 is mounted on the pallet conveying path 12 to be capable of running thereon. With this arrangement, when removing the current collecting pallet from the pallet conveying path for transportation and storage, it becomes possible to avoid damages of the current collecting block and the guide roller. Thus, handling is made easy.

Description

[Detailed description of the invention] The present invention relates to a current collecting pallet device.

Inspections in the production process of electrical products such as televisions, radios, washing machines, etc. are carried out by moving the iRlet on which the electrical products are placed on a continuous line and carrying out various tests (current, voltage, etc.).
In order to perform these inspections, a current collecting pallet device as shown in FIGS. 1 to 4 has conventionally been used.

The current collecting pallet device includes a pair of power feed rails 4.4 each having a power feed band conductor 3 held by an insulating material 2 on both sides of the upper surface of a pallet conveyance path 1 consisting of a roller conveyor. The conductors 3.3 are arranged in parallel so as to face each other, and are attached in the protruding direction by compression coil springs 6 to both sides of the rectangular collector pallet 5 which is placed on the pallet transport path 1 so as to be freely movable. Guide rollers 10 are provided on both sides of the current collecting pallet 5 so that the retractable current collecting block 7 is connected to the outlet 9 via the current collector 8, and in contact with the insulating material 2 of the power supply rail 4. It was rotatably attached to a shaft, and had a structure in which a current collector 8 supplied electricity from a power supply band conductor 3 to an outlet 9, and guide rollers 10 allowed smooth running.

According to such a conventional current collecting pallet, when the current collecting pallet 5 is removed from the pallet conveyance path 1 for storage or transportation, the current collecting blocks 7 protruding from both sides of the current collecting pallet 5 and the idle rollers 10 The drawback was that it was easily damaged by contact with machinery in buildings and factories.

Furthermore, in order for the guide rollers 10 to move smoothly in the traveling direction, it is necessary to provide them at the front and rear of both sides, and at least 4
This guide roller 10 was required.

The present invention has been made in view of the above point 1, and its purpose is to reduce the number of idle rollers so that the current collecting block portion is less likely to malfunction during handling when removed from the pallet conveyance path. The object of the present invention is to provide a current collecting pallet device that can run smoothly using idle rollers.

Hereinafter, a current collecting pallet device will be explained based on FIG. 5 showing an embodiment of the present invention.
A pair of power supply rails 15.15 holding 3.13 with an insulating material 14.14 (3) are arranged in parallel with the respective power supply conductors 13.13 facing each other in the conveying direction. The power supply rail 1 is attached to the lower surface of the current collection pallet 16 which is placed on the road 12 so as to be freely movable.
5 is formed, and this groove 17 is formed.
A current collector block 19.19 having a pair of current collectors 18.18 in contact with each power supply conductor 13.13 of the front Jt2 power supply rail 15 is protruded inside. This current collecting block 19 is the third
Similar to the conventional example shown in the figure, the current collector disposed on the front surface of the insulating stand comes into elastic contact with the feed band conductor due to the bias of the compression coil spring. A guide roller 2 is also provided in the groove 17 so as to be guided in contact with the power supply rail 15.
0 is provided protrudingly, and its positions are provided in the front and back in the conveying direction. Note that the position and number of guide rollers 20 may be arbitrarily selected depending on the running condition.

The current collector 18 of the current collector block 19 and the electrical outlet (21 +i) disposed on the upper surface of the current collector pallet 16 are electrically connected.

(4) Because of this configuration, even when the current collecting pallet 16 is removed from the pallet transport path, the current collecting block 19 and the guide roller 20 are located within the groove 17 on the lower surface, so that the current collecting pallet 16 It is protected by the main body, and it is extremely unlikely to be damaged during handling.
Since it is hidden inside, workers are less likely to get an electric shock accident. Furthermore, in order to make the current collecting pallet 16 run smoothly, only two guide rollers 20 are required, one at the front and the other at the rear, thereby reducing the number of parts.

As described above, the current collecting pallet device of the present invention includes a pallet conveyance path, a power feed rail having a pair of power feed lines arranged on the pallet conveyance path, and a concave groove in the lower surface that allows the power feed rail to enter. and a current collecting pallet that is movably placed on the pallet conveyance path, and a current collecting pallet that protrudes into the groove and contacts the power feeding line of the power feeding rail to establish an electrical connection between the current collecting pallet and the feeding line. Since it is equipped with a pair of current collecting blocks and a guide ring that protrudes from the groove and is guided in contact with the power supply rail, the current collecting pallet is removed from the bar 1/tot conveyance path and transported. The current collecting block and guide rollers will not be damaged during storage, making handling easier, and the power supply rails are also hidden by the concave grooves of the current collecting pallet, making it electrically safe. Further, there is an effect that smooth movement can be performed with a small number of guide rollers.
