Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular ceramic substrate used for manufacturing a thermal print head, or a rectangular plate-shaped body such as a rectangular lead frame used for manufacturing electronic parts. The present invention relates to a device for positioning the device in a fixed posture so that it can be stored in the magazine and then storing it in the magazine as it is.

[0002]

2. Description of the Related Art Generally, in manufacturing a thermal print head, an electrode pattern or a resistor is formed on the surface of a rectangular ceramic substrate while being transferred in a line by a conveyor or the like. A plurality of sheets of the above are sequentially stored in a magazine, and in the state of being stored in this magazine, they are supplied to various subsequent processing steps.

When the ceramic substrate is placed on a conveyor and is transferred, during the transfer,
Since the ceramic substrate shifts to one side of the conveyor or tilts with respect to the transfer direction of the conveyor, it cannot be stored in the magazine as it is. Therefore, conventionally, at the end portion of the conveyor, the transfer of the ceramic substrate on the conveyor is stopped, and in this state, the ceramic substrate is moved by a lateral movement mechanism such as a plunger arranged on the side portion of the conveyor. By laterally moving laterally with respect to the transfer direction, one side surface of the ceramic substrate is pressed against a positioning member arranged along the conveyor,
Position in a certain posture, then in this posture,
After being placed on the feeding member and lifted from the conveyor, it is fed and stored in the magazine.

[0004]

However, in this conventional device, At the end of the conveyor, a lateral movement mechanism such as a plunger for moving the ceramic substrate on the conveyor in the direction toward the positioning member is required. Therefore, the structure of the apparatus becomes complicated, and the manufacturing of the apparatus becomes complicated. Not only will the price increase, but the size of the device will increase. . Since the transfer of the ceramic substrate is temporarily stopped at the end portion of the conveyor, the ceramic substrate is laterally moved laterally, thereby requiring a positioning time for positioning the ceramic substrate in a certain posture. The speed of storing the board in the magazine is so slow. . When the lateral width dimension of the ceramic substrate to be handled changes, the distance of the widthwise movement by the lateral movement mechanism has to be changed, which is extremely troublesome to operate. . The ceramic substrate shifts until it is stored in the magazine by placing it on the feeding member, so that the ceramic substrate cannot be correctly stored in the magazine and the ceramic substrate falls from the feeding member. . There was a problem to say.

According to the present invention, it is necessary to position a plate-like body such as a ceramic substrate transferred by a conveyor in a certain posture and then to send it into a magazine for storage, as in the prior art, because the apparatus becomes complicated and large in size. It is a technical object to provide an apparatus capable of surely performing at a high speed without causing a change.

[0006]

In order to achieve this technical object, the present invention provides a positioning member at a position rearward of the end of a conveyor for transferring rectangular plate-like bodies such as ceramic substrates in a line. An inclined transfer provided so as to extend along the transfer direction of the conveyor, and one of the left and right sides of the positioning member inherits the rectangular plate-shaped body from the conveyor and transfers the inclined plate toward the positioning member. Type conveyors, and on the other hand, magazines for accommodating the rectangular plate-shaped bodies are arranged respectively, and the tip end surface of the rectangular plate-shaped bodies being transferred is in contact with the terminal end of the inclined transfer type conveyor. While providing a stopper for positioning the rectangular plate-shaped body so that it can be stored in the magazine, the inclined transfer type conveyor is provided at least at both the front end and the rear end of the inclined transfer type conveyor. A feed member configured to move upward from below to move upward into the magazine, move laterally into the magazine, and then move downward, and further connect the inside of each of the feed members to a vacuum source. The open top is made hollow, and a porous body such as a wire mesh is attached to the open top. "

[0007]

[Operation] In this configuration, the rectangular plate-like body transferred by the conveyor is inherited from the end of the conveyor to the inclined transfer type conveyor. Then, the rectangular plate-shaped body is transferred in an inclined shape toward the positioning member by the inclined transfer type conveyor, so that one side surface of the rectangular plate-shaped body contacts the positioning member while being transferred. The rectangular plate-shaped body is stopped because the tip end surface of the rectangular plate-shaped body contacts the stopper and the transfer is stopped during or after the width-adjustment. , One side of which is in contact with the positioning member and the tip end of which is in contact with the stopper, that is, a certain attitude that allows the magazine to be stored in the magazine as it is.

In this way, when the rectangular plate-like member is positioned on the inclined transfer type conveyor in a fixed posture so that it can be stored in the magazine as it is, the respective feeding members are directed upward from below the inclined transfer type conveyor. By ascending, the rectangular plate-shaped body whose positioning has been completed is scooped up on the inclined transfer type conveyor, and then each of the feeding members is moved laterally toward the inside of the magazine and then descended, thereby The rectangular plate is stored in the magazine.

Further, each of the feeding members is formed in a hollow shape having an open upper surface, the inside of which is connected to a vacuum generating source, and a porous body such as a wire mesh is attached to the open upper surface. Since the rectangular plate-shaped body can be vacuum-sucked to each of the feeding members, the rectangular plate-shaped body can be sucked into the magazine from the inclined transfer type conveyor by the feeding member. It is possible to prevent the plate-shaped body from shifting.

[0010]

Therefore, according to the present invention, Since the rectangular plate-shaped body can be automatically positioned while being transferred by the inclined transfer type conveyor, the rectangular plate-shaped body can be positioned in a fixed posture so that it can be stored in the magazine. Since it does not require time for positioning by moving the rectangular plate,
The speed of storing in the magazine can be greatly improved. . Since the rectangular plate-shaped body can be automatically positioned while being transferred by the inclined transfer type conveyor, the rectangular plate-shaped body can be positioned in a fixed posture so that it can be stored in the magazine. Since the lateral movement mechanism for shifting is not required, the structure of the device is simplified, the device can be provided at low cost, and the device can be downsized. . Since the rectangular plate can be positioned in a fixed posture so that it can be stored in the magazine automatically while being transferred by the inclined transfer type conveyor, even if the width of the rectangular plate changes. Since the above-mentioned positioning can be performed reliably, the adjustment operation accompanying the change in the lateral width dimension of the rectangular plate is not required. . The rectangular plate-shaped body can be prevented from shifting while being fed into the magazine from the inclined transfer type conveyor by each of the feeding members. In other words, the rectangular plate-shaped body can be kept in a constant posture. Since it can be fed to the magazine while it is positioned, the reliability of feeding and storing in the magazine can be improved.When storing and feeding in the magazine, the rectangular plate collides with the magazine or falls from each feeding member. By doing so, it is possible to greatly reduce damage to the rectangular plate-shaped body. Has the effect of saying.
