Description of the Related Art Conventionally, as shown in FIG. 2, a work take-out / conveying device of this type guides the side surface of a work 19 conveyed on a conveyor 18 and aligns the work 19 in order to move the work 19 up and down. A guide 11 is provided above the rear part of the conveyor. Further, the work is aligned within a predetermined range in the alignment guide 11, and when the predetermined quantity is sent to the next process, the work is vertically moved by an air cylinder 12 for preventing an extra work from entering the alignment guide 11. The shutter 13 to be operated, the number of workpieces aligned in the alignment guide 11, the sensor 14 for observing the timing of lowering the shutter 13, and the work aligned in the alignment guide 11 are next. In order to send it to the process, it can be slid at right angles to the conveying direction of the conveyor, and is composed of an extrusion plate 16 provided with a stopper 15 for stopping the work. The number of workpieces 19 aligned within a predetermined range (length) in the alignment guide 11 is counted by the sensor 14, and when the specified number is counted, the shutter 13 is lowered and the workpieces are inserted into the alignment guide. Prevent the entry. As for the timing of the shutter 13 descending, the sensor 14 detects a specified number of workpieces on the assumption that the work 19 conveyed on the conveyor 18 maintains a constant interval, and The shutter 13 is descending under the control of a timer in relation to the transport speed. Therefore, if the moving distance or moving speed of the work changes due to some event while the work 19 is being carried to the shutter 13, the shutter 13 will carry the work at a constant interval. Since the operation is performed on the assumption that the shutter 13 comes down, there is a problem that when the shutter 13 descends, the work is crushed and the product or machine is damaged.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has changed the alignment guide, which has conventionally been moved up and down, so that it slides in a direction perpendicular to the conveying direction of the conveyor. The conventional extruding plate was abolished by attaching a stopper for stopping the work that was attached to the extruding plate in the conventional device to the alignment guide. Also, with the conventional device, the shutter that had been moved up and down was abolished, and the work was stopped by pressing it against the wall surface of the proposed rod, etc., provided on the side of the conveyor using an air cylinder, etc. A clamp is provided. Further, a slide stopper that slides forward and backward with the stopper as a boundary is provided in the stopper portion of the alignment guide in the same direction as the convey direction of the conveyor. The sensor that used to count the number of workpieces and detect the timing to lower the shutter was abolished in the conventional device, and a sensor was installed in front of the clamp. When a predetermined number of work pieces are arranged in a predetermined range inside the clamp part, the work pieces are detected by a sensor and the work pieces are clamped by the clamps. The slide stopper at the rear end of the aligned work slides backward, and the work row on the lower side in the transport direction of the clamped work moves with each row, and the predetermined number of work rows are separated and used as the alignment guide. It will be stopped by the attached stopper. The alignment guide slides in the direction perpendicular to the conveyor direction, and is transferred to the pedestal that is sent to the next process. Therefore, by clamping a part of the middle of the work line arranged in a series, even if the distance between the works being transferred changes due to some event, a work take-out transfer device that does not damage the works can be provided. provide.

That is, in a work unloading / conveying device for sequentially arranging works conveyed on a conveyor in series, separating only a predetermined number of works within a predetermined range, and sending the work to the next process, At least two plates arranged at the end of the conveyor, fixed to the rear of the stopper having a plane surface in the work direction, and connected to a driving device for sliding in the direction perpendicular to the conveyor conveying direction. -Shaped alignment guide, a clamp that is placed immediately before the alignment guide on the conveyor, and is connected to a drive device that can move back and forth between the guide rod and the conveyor, and inside the alignment guide on the conveyor. And a slide stopper connected to a driving device for sliding the conveyor in the same direction as the conveying direction of the conveyor. And a work picking and conveying device.

[0006]

[Action]

 According to the present invention, a slide stopper that slides in the same direction as the convey direction of the conveyor is provided as a stopper for stopping the work conveyed on the conveyor, in addition to the stopper attached to the alignment guide. While the workpieces are aligned in the alignment guide, the tip of the slide stopper is located inside the stopper. A predetermined number of workpieces are aligned in a line in the alignment guide, and an extra row of workpieces is subsequently aligned. Here, when cutting out only the specified amount of work, the clamp connected to the air cylinder is operated to prevent the work outside the specified amount from entering the alignment guide, and the work is guided to the guide rod on the conveyor. Press it down to temporarily stop the work. The operation of the clamp part is such that when the clamp parts are aligned one by one in front of the clamp part, a sensor installed in front of the clamp part detects that the workpieces are aligned in a specified number or more, and is defined by the clamp. Send a signal to operate to stop the next work of the number. When the specified number of workpieces is clamped and stopped, the slide stopper slides backward, and when it comes out of the alignment guide, the specified number of workpieces aligned in the alignment guide remain aligned in series. It is transported to the rear and is stopped by the stopper attached to the alignment guide, and is separated by the specified amount in the aligned state. By sliding the alignment guide laterally, a predetermined quantity can be cut out and sent to the receiving portion in the next process.
