Abstract

PURPOSE:To improve the degree of straight movement, by a method wherein, in a roller device for conveying strip-shaped plated object such as IC reed frames, rollers, which respectively have a flat central part, having a width narrower than that of the object to be conveyed, and slanted end parts, are pivotally secured so that they can be freely vibrated. CONSTITUTION:Lower edges 16 on both sides in the direction of width of an object 4 to be conveyed, which is conveyed in the direction of an arrow mark, are supported by opposite upward slanted parts 6, and the object is conveyed in a direction A through rotation of rollers 2. In which case, the slanted part 6 has a slanted angle of 3-30 deg., and the object to be conveyed is vibrated through a bearing 3, a shaft 7, and the roller 2 by means of a vibrator 13, whereby an automatic centripetal force is exerted on the object 4 to be conveyed, a zigzagging distance in a lateral direction is decreased, and automatic regulation is effected so that the center in the direction of the width of the roller 2 coincides with the center of the object 4 to be conveyed. This constitution permits improvement of the degree of straight movement.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roller device suitable for transporting CIJ frames and other strip-shaped plated objects on a plating line to or from a plating machine.

Roller devices of various shapes and structures have been used in the past, but roller devices used for feeding in a desired direction on a strip-shaped plating line usually have a width that is significantly larger than the width of the conveyed object (plated object). In most cases, the 1,000 rollers are simply cylindrical rollers, and in order to move multiple objects in parallel in a straight line without meandering, the two-flat rollers are equipped with a pair of left and right guide rollers in the shape of an abacus bead. Although combinations of rollers or stepped rollers are used, it is difficult to move various conveyed objects of different widths in a straight line without meandering when used alone. The reality is that the type of roller is replaced each time, and the guide rollers and stepped rollers are rearranged accordingly.

The present invention is a roller device developed in response to the current situation, which has the requirement of υ even for strip-shaped objects having different widths, and also allows straightness of the object to be transported with one type of roller. The purpose is 1- to provide a roller device that can apply 4)

Specifically, the mouthing device according to the present invention is provided with a flat part in the center having a width smaller than the width of the object to be conveyed, and an upwardly sloped part with a slope of 3 to 300 on both sides. The roller is supported by a bearing part so as to be able to vibrate freely.

The details of this invention will be explained below with reference to the drawings. 1 and 2 are diagrams showing a first embodiment of the present invention, and this roller device 1 is provided with a flat portion 5 having a width W2 smaller than W1, and a flat portion 50 having a width W2 smaller than W1. Upward slope portions 6 with slope angles θ of 3 to 300 are provided on both sides.

The width W2 of the flat portion 5 is preferably 31 or more smaller than the width W1 of the object to be transported 4. If the inclination angle θ is 2° or less, it is difficult to reduce the amount of meandering in the transport direction, making it difficult to
If it exceeds 100°, the maximum conveyance width W tends to become small, and the adaptability and versatility to conveyed objects 4 of different width sizes are lost. This is undesirable because the difference in height becomes large when receiving and passing objects to be transported.

The roller 2 is mounted double-mounted on a shaft 7, and its left and right ends are supported by bearings 3. The shirts are arranged side by side on the shaft 7 with the upwardly inclined parts 6 adjacent to each other, and are rotated together with the shaft T while being supported by the bearing part 3. Four rollers 2 are arranged in the direction of arrow A, and these four rollers 2 are supported by a common bearing part 3 through a shaft 7. Rubber and other anti-shock materials 9 on each side
．． 10 cars are installed and fixed to the base 8 with bolts 11 and 12. A vibrator 13 is mounted on the outside of the base 8 adjacent to the bearing part 3, and is connected to the bottom part 3a of the receiving part 3 via an arm-shaped mounting plate 14.・Bearing part 3
015 are bearing grooves, which are formed at four equal intervals in the direction of arrow A in the bearing part 3 in order to mount the end of the shaft I. . The bearing portions 3 are arranged as a pair of left and right bearings facing each other, but since they have substantially the same structure σ), only the right bearing portion 3 is shown and the left one is omitted. Various types of vibrators can be used as the vibrator 13, and any vibration generator can be used as long as it can apply appropriate vibrations from the bearing section 3 to the shaft to the roller 2.

Next, enclose the action.

The conveyed object 4 that has been conveyed in a parallel state on ordinary rollers (for example, flat rollers) in the direction of arrow A passes over four rollers 2 (1) 11, which are given straightness. and the distance between them in the parallel state will be automatically adjusted. That is, the lower edges 16 on both left and right sides in the width direction of the conveyed object 4 can be accepted within the range of the maximum conveyance width W even if the width W1 differs for each suitable conveyed object 4, and the lower edges 16 have both upward slopes. 6, and is pushed in the direction of arrow A by the rotation of the rollers 20 (that is, the rotation of both inclinations g+the rotation of the part 6), and the whole is conveyed. Arrow A
The conveyed object 4 being pushed in the direction has both upward slopes 6 3~
It has an inclination angle of 30°, and the vibrator 1
3. Based on the above, automatic centripeting, or centering, is always performed to reduce the meandering amount in the conveying direction so that the widthwise center of the roller 2 and the widthwise center of the conveyed object 40 match. You will have to adjust your position on your own. Therefore, the conveyance speed of each conveyed object 4 is also kept approximately constant, and when a plurality of rows of rollers 2 are provided via the shaft 7 and the conveyed objects 4 are caused to flow in each row, the conveyed objects 4 in each row are This means that there is no variation in the conveyance speed of the objects 4, and they can all be moved straight and conveyed at substantially the same speed while maintaining an aligned state, making it easy to perform plating and other types of processing on the objects 4 in each row at the same time.

FIG. 3 is a diagram showing a second embodiment of the invention. In the roller 2a of this embodiment, both sides of the flat portion 50 have an inclination angle of 01. Two uphill sections fl, 5b with different θ2
are formed continuously, and the inclination angle θ1. The relationship between θ2 is θ1 × θ, and θ1. Both θ2 are set within the inclination angle range of 3 to 30 degrees, and the conveyed objects 4 have different widths W.
It increases the adaptability to two types of uphill slopes (ia

In both the first and second embodiments, the inclination angles θ, θ8, . θ2
If it is set so that it goes from small to dog (slow to steep) in the conveyance direction, it will be easier to reduce the amount of meandering for position regulation and to even out and maintain a constant conveyance speed. Become.

Since the roller reinforcing according to the present invention has the above-mentioned contents, it is possible to carry objects having different suitable width sizes as long as the distance between both ends of both upwardly inclined portions of the roller is within the range of 2, that is, the maximum conveyance width. The conveyed object that can be accepted and conveyed, and that is accepted within this maximum conveyance width, has its lower edges at both ends in the width direction supported by both upward slopes of the roller, and while being pushed in the conveyance direction, the conveyed object is It automatically centripetes according to the inclination angle of the upward slope and also according to the vibration of the roller from the bearing part, and the amount of meandering is reduced by position control, so the object to be conveyed can move straight and be conveyed at a constant speed. There is.
