Meantime, receiving rollers 24 are made to rotate in the same direction with the transport direction of the conveyer 1, and also, at the same transport speed. Accordingly, an IC base plate 36 is moved at a correct posture from the conveyer 1 to receiving rollers 24, and transferred to the receiver 20 through receiving rollers 25. Next, stoppage is made on receiving rollers 19, and the base plate 36, together with the receiver 20, is lifted up by means of a cylinder 10, and transferred to the 2nd conveyer 4. As a result, transfer can be done with a marshaling posture retained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to transferring a conveyed object formed into a rectangular plate shape, such as a hybrid IC substrate, from a first belt conveyor to a second belt conveyor using a receiver. The present invention relates to an improvement in which an object conveyed by the first belt conveyor can be sent to a receiver without changing its conveying posture.

[Conventional technology]

Generally, a hybrid IC substrate is formed into a rectangular shape using ceramics as a material, and after a conductive metal is printed along a circuit pattern on the front or both sides of the board, it is transported to a firing process (and a drying process). In the firing step (drying step), the hybrid IC substrate is fired (dried) while being conveyed in a firing furnace (drying furnace) by a mesh belt conveyor. The hybrid IC substrate that has been fired (dryed) and taken out of the firing furnace (drying furnace) is transferred to another belt conveyor via a receiver in the transfer device, and then transported to the next process by the same belt conveyor. Ru.

Conventionally, in the above-mentioned transfer device, as one of the means for feeding objects conveyed by the conveyor, such as hybrid IC boards, carried by the mesh belt conveyor, to the receiver in an aligned state without causing any inclination in the feeding posture, The mesh belt conveyor has a rotating shaft extending in the belt width direction and rotatably horizontally mounted on the belt turn part of the mesh belt conveyor, and the rotating shaft is in the same direction as the belt turning direction.

A method has been proposed in which the belt is rotated at a circumferential speed slightly higher than the transport speed of the mesh belt conveyor. FIG. 6 is a drawing showing the specific structure thereof, in which a is a first belt conveyor, and b is a second belt conveyor disposed extending in a direction orthogonal to the first belt conveyor a. , C
denotes a transfer device interposed between both belt conveyors a and b, and f denotes a hybrid IC board, respectively. In the same transfer device [c, d is a receiver bent into an L-shape and formed into a fork shape (comb tooth shape), and the receiver d is connected to the first belt via a cylinder g and a cam mechanism. It is provided so that it can move forward and backward in the conveyance direction of the conveyor a, and can swing freely in the vertical direction, and when receiving the hybrid IC board f, there is a downward slope from the tip toward the base, so that the tip is above the It is provided so as to face the belt turn part of the belt conveyor a. In addition, at the belt turn part, a round rod-shaped material is made of metal such as stainless steel and is located in front of the position where the tip of the receiver d faces and corresponds to the position where the hybrid IC board f starts to slide down. The forming rotating shaft e extends in the belt width direction and is rotatably horizontally mounted in the same direction as the belt turning direction and at a circumferential speed slightly higher than the conveying speed of the mesh belt conveyor. When the hybrid IC substrate f conveyed on the belt conveyor a slides down at the belt turn section, the hybrid IC substrate f is once brought into contact with the outer peripheral surface of the rotating shaft e to adjust its feeding posture. Thereafter, the receiver d is provided so as to be slid over the rotary shaft e and onto the receiver d through the rotational action of the rotary shaft e.

[Problem to be solved by the invention]

However, in the above-mentioned conveyor-transported object transfer device, a rotating shaft is rotatably horizontally mounted on the belt turn section, and the conveyed object that begins to slide down the belt turn section temporarily hits the rotating shaft. After making contact, it is designed to slide over the rotating shaft and slide down on the receiver, so if the rotating shaft is sufficiently straight, it is possible to smoothly correct the feeding posture of the conveyed object. However, if the rotating shaft does not have sufficient straightness, the object may be transported in a straight state due to eccentric rotation of the rotating shaft. This is a problem in which the conveyed object slides down on the receiver with its feeding position tilted diagonally.In other words, the conveyed object is delivered to the second belt conveyor with its feeding position tilted diagonally. The problem is that it causes the inconvenience of In this way, by conveying objects such as hybrid IC substrates on the second belt conveyor with their feeding posture tilted diagonally, for example, hybrid IC substrates are automatically transferred to the magazine. When storing the magazine, since the magazine is formed with the same opening width as the width of the transported object, the transported object will not fit smoothly into the magazine.
This results in problems such as cracking and deformation.

The present invention attempts to improve the above-mentioned problems, and the purpose of the present invention is to improve the hybrid IC.
The object of the present invention is to enable conveyed objects such as printed circuit boards to be fed to a receiver without causing any inclination in the feeding posture. That is, in the present invention, instead of the conventional method in which the conveyed object is corrected in its feeding posture by the rotating shaft at the belt turn section and then allowed to slide down naturally onto the receiver, the conveyed object is moved onto the conveyor by a plurality of receiving rollers. By forcibly feeding the material from the very end in the conveyance direction to the receiver, and because the rotating shaft was conventionally made of metal such as stainless steel, it was difficult to achieve elegant machining and sufficient straightness. In addition, the receiving roller was easily prone to plastic deformation due to external force, but the above problem was solved by forming the receiving roller using carbon fiber with excellent straightness. The specific means and effects are as follows.

[Means to solve the problem]

A receiver formed by arranging a large number of receiving members in a comb-like shape is provided so as to be movable forward and backward, facing the end of the first belt conveyor in the conveyance direction, and the receiver is advanced to allow the conveyor to be conveyed on the belt conveyor. In a transfer device that is provided to receive a conveyor-transferred object, move the receiver backward, and transfer the conveyor-transferred object onto a second belt conveyor disposed in a direction perpendicular to the first belt conveyor, A plurality of receiving rollers are arranged between the conveyance direction end of the first belt conveyor and the receiver and extend in the belt width direction of the belt conveyor, and are arranged at regular intervals. The belt conveyor is rotatable in the same direction and has the same circumferential speed as the conveyance speed of the first belt conveyor.

■ A part of the above-mentioned receiving roller is provided with an annular groove carved in its outer periphery in correspondence with the bottom of the receiving member, so that the outer periphery of the receiving roller can be exposed above the bottom of the receiving member. Make it.

■ The above receiving roller is formed using carbon fiber as a material.

[For production]

■ The conveyed object that has been conveyed all the way on the first belt conveyor can be smoothly transferred onto the receiving roller without tilting the feeding posture, and the receiving roller can also move the conveyed object in its feeding posture. An effect of forcibly conveying it toward the receiver without breaking it can be obtained.

(2) When the receiver receives the conveyed object, the receiving member fits into the annular groove carved in a part of the receiving roller, so that the outer circumference of the receiving roller faces above the bottom of the receiving member.

By arranging the outer periphery of the receiving roller to face above the bottom of the receiving member, the conveyed object can be reliably sent onto the receiving member through the forced conveying action of the receiving roller.

■ By forming the receiving roller using carbon fiber as a material, the straightness of the receiving roller can be improved. That is, by using a receiving roller with excellent straightness, an effect of feeding the conveyed object to the receiver without causing an inclination in the feeding posture can be obtained.
