[0014]

Before explaining the operation of the work constant pitch feed apparatus according to the present invention, an outline of a work constant pitch feed method using this apparatus will be described. At the beginning of work,
The feed claw attached to the claw mounting plate is projected above the processing rail. The work is supplied between the feed claw at one end of the claw mounting plate and the feed claw adjacent to the claw mounting plate, and the claw mounting plate is moved by one pitch in the work feeding direction by the left and right moving means to move the work by one pitch. Can be made. When the pawl mounting plate is moved in the direction away from the processing rail by the front-rear moving means, the work is opened to that position, and processing such as press fitting of the sealing material can be performed. Subsequently, the claw mounting plate is moved by one pitch in the direction opposite to the workpiece feeding direction by the left and right moving means, and the claw mounting plate is moved in the direction of the machining rail by the front and rear moving means to project the feed claw onto the machining rail. And return to the state at the start of work. The first work remains in a state of being fed by one pitch (between the second feed claw and the third feed claw from the end portion of the claw mounting plate) and completes one work unit. Next, the next work is supplied between the feed claws at the end. By repeating this process, a plurality of works can be transferred at a constant pitch.

The work constant-pitch feeding device of the present invention having the above-described structure has the respective structures that operate as follows, and can move the work at a constant pitch while processing the work. That is, in the work constant-pitch feeder according to claim 1, since the feed pawls are provided on the pawl mounting plate at regular intervals, each work is held between the feed pawls. It is possible to make the interval constant and to simultaneously move a plurality of works in a fixed direction.

In order to feed the work piece at a constant pitch, as described above, the claw mounting plate is moved in the front-rear direction (direction orthogonal to the work piece feed direction and close to or away from the machining rail), and , It is necessary to be able to move in the left-right direction (work feed direction and the opposite direction). The front-back movement means moves the claw mounting plate back and forth, and the left-right movement means moves the claw mounting plate left and right. In order to operate the front-rear moving means and the left-right moving means in a mutually correlated manner, a drive shaft equipped with a rotating disk and a left-right moving cam is supported as a driving means in parallel with the workpiece feeding direction. It is provided. The rotating disk actuates the front-rear moving means described later, and the left-right moving cam operates the left-right moving means described later. Since they are provided on the same shaft, they can operate in a timely manner in relation to each other.

The work feeding means according to a second aspect of the present invention includes a power receiving plate, a claw mounting plate, a front and rear slide unit, and a left and right slide unit. The power receiving plate receives a force that moves in the front-rear direction from the front-rear moving means. Since the power receiving plate and the pawl mounting plate are supported by the same front and rear slide unit, the pawl mounting plate can be moved back and forth by the force received by the power receiving plate. Further, since the lower part of the front-back moving slide unit is supported by the left-right moving slide unit, the entire work feeding means can be moved right and left by the left-right moving means which will be described later.
With this combination, the pawl mounting plate moves back and forth and right and left, and the work can be fed at a constant pitch by the feed pawls provided on the pawl mounting plate.

The front-rear moving means of the third aspect comprises a contact plate, a power transmission shaft, a power transmission plate and a push roller. When a force is applied to the contact plate in the forward direction (direction close to the processing rail) by the rotating disk of the drive means which will be described later, the power transmission base moves the integrated power transmission shaft in the forward direction. . The power transmission shaft moves the power transmission plate via the passive ring by a stopper and a spring provided at one end thereof. The work transfer means can be moved by a push roller provided at the tip of the power transmission plate. Since the power transmission base is always pulled backward by a pull-back spring, for example, a coil spring, the power transmission base moves backward (away from the processing rail) when the force pushing in the forward direction disappears.

The left and right moving means of the present invention comprises a weight, a roller support, and a wire connecting them to the left and right slide units of the work feeding means. Tension is always applied to the left and right slide units in the work feed direction by the weight. When the roller support member provided in constant contact with the left / right moving cam provided on the drive shaft moves according to the rotation of the left / right moving cam, the wire connected thereto is pulled or loosened to move the left / right slide unit. Can be moved to move the claw mounting plate left and right. According to a fifth aspect of the present invention, in the left-right movement means, the left-right movement cam provided on the drive shaft of the fourth aspect is used as a cylindrical cam, and a roller support and a wire for contacting the left-right movement unit to move the left-right slide unit are used as bearings and arms. It has been changed.
As a result, the structure of the device is simplified and the movement accuracy of the left and right slide units can be further improved.

According to a sixth aspect of the present invention, the driving means includes a drive shaft, a rotating disk and a left / right moving cam. The drive shaft is a drive source of the workpiece constant pitch feed device of the present invention, and a rotational force is given by a power source (not shown). The rotary disc is provided with a feed roller, and by the rotation of the rotary disc, the feed roller can push the contact plate of the front-rear moving unit forward and move the front-rear moving unit forward. When the left / right moving cam rotates, the roller support or bearing that abuts on the left / right moving cam is moved to move the left / right moving means to the left or right.

The work constant-pitch feed device of claim 7 is a concrete combination of the main constituent features of the work constant-pitch feed device of claim 1 according to claims 2 to 5, and each requirement is satisfied. Has the above function.

The detecting means and the popping-out means of claim 8 are one of the work processings attached to the work constant-pitch feeding device. For example, the detection means and the popping-out means are combined with the step of press-fitting the sealing material into the bearing (work), When inspecting the performance of the press-fitting process, the height of the bearing (workpiece) is detected to detect whether or not the seal material has been press-fitted correctly, and based on the result, it is attempted to utilize it in the process of popping out rejected products. It is a thing. That is, the detection means includes a slide unit, a moving plate, a guide shaft, and an upper / lower limit sensor. The movable plate, which is supported by the slide unit so as to be freely movable in the vertical direction, has the other end supported by a rotating body placed on a flat cam attached to the pawl mounting plate. As the claw mounting plate moves back and forth, the moving plate moves up and down. The guide shaft moves up and down in accordance with the movement of the moving plate, and the height of the work (bearing) supplied below it can be detected by the upper and lower limit sensors.

On the other hand, the repelling means includes a repelling cam, a repelling roller and a repelling plate. In response to the defective product removal signal from the detection means, the ejecting cam rotates, the ejecting roller abutting on the ejecting cam moves toward the processing rail, and the ejecting plate integrated with the ejecting roller causes the ejecting roller to move. The work on the processing rail can be pushed out.
