Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for, for example, in a production line of engine valves, for loading a fixed amount of work conveyed by a parallel-bar chute that inclines downward into a container or the like prepared below the lower end of the chute.

[0002]

[Prior art]

 The engine valve is manufactured through many processes, and when one process is completed, a large number of works transferred by a downwardly inclined parallel bar chute may be put into a net cage and supplied to the next process. At this time, in order to control the number of work lots, it is necessary to accurately grasp the number of works thrown into the net cage, and in the past, an operator grips multiple works with a fork-shaped jig. Then, it was thrown into the basket while counting manually.

[0003]

[Problems to be solved by the device]

 Therefore, it not only takes a lot of labor to save labor, but it may reduce productivity or make a mistake in counting, which may hinder lot number management.

The present invention has been made in order to solve the above-mentioned problems, and saves labor by automatically loading a fixed number of works transferred from a chute into a container or the like. It is an object of the present invention to provide a constant number feeding device for work that enables easy control of the number of lots of work.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a lower end of a chute for transferring a work and a predetermined number of works separated from the lower end of the chute, and a control device alternately controls the work transfer chute into the work transfer path. A first selector device and a second selector device to enter are provided, and a sensor for detecting the presence or absence of a work piece in the rearmost portion stored in a predetermined number is provided at a position close to the second selector device. By detecting the stop of the work of the part, the second selector device is operated to close the conveyance path, and at the same time, the first selector device is operated while a predetermined number of works pass to open the conveyance path. It is characterized by doing so.

[0006]

[Action]

 In the device of the present invention, when the first selector device closes the work transfer path and the work that slides down from above the chute is stored in a predetermined number between the first selector device and the second selector device, the sensor will The second selector device automatically closes the transport path by detecting that the work of a certain section is stopped for a certain period of time, and the first selector device opens the transport path, and the predetermined number of accumulated work Will slide down and be put into a container.

[0007]

【Example】

 The drawing shows an embodiment of the present invention, in which a umbrella (1a) of a work (1) such as an engine valve is suspended and slid downward by its own weight to carry it by parallel bar type shoots. The first solenoid (3) and the second solenoid (4), which are selector devices, are located near the front lower end of (2) and above the rear upper part with a space corresponding to, for example, 10 workpieces (1). And are provided. Both of these solenoids (3) and (4) are provided with a first stopper (5) and a second stopper (6) which alternately enter the conveyance of the work (2) from the side.

A proximity sensor (7) for detecting the shaft portion (1b) of the work (1) is provided slightly below and below the second stopper (6), and both solenoids (3) (4) and the proximity sensor are provided. (7) is electrically connected to a control device (8) provided in a proper place. A net basket (9) is provided below the lower end of the chute (2).

In the above-mentioned device, when the control device (8) automatically advances the first stopper (5) to close the transport path, the second stopper (6) immediately retracts to open the transport path. Then, the work (1), which is then sent upward or intermittently in sequence, slides down by its own weight toward the first stopper (5).

Then, when the tenth work (1) stops to the side of the proximity sensor (7) and the detection time by the proximity sensor (7) reaches a predetermined time, the ten work (1) Is detected, the control device (8) advances the second stopper (6) and at the same time retracts the first stopper (5). Then, the ten works (1) stored between the stoppers (5) and (6) continuously slide down into the net cage (9).

Since the time required for the 10 works (1) to slide into the net cage (9) is almost constant, after the lapse of a certain time or more, the control device (8) again causes the first stopper (5) to move. When closed, the second stopper (6) opens.

By repeating the above-mentioned operation, the workpieces (1) sent to the chute (2) are thrown into the net cage (9) by 10 pieces each, and the stoppers (5) or (6) at that time are loaded. When the control device (8) counts the number of times of operations, the cumulative number of charges can be displayed on a counter (not shown).

The device of the present invention does not limit the number of workpieces (1) to be thrown in at one time to ten, but an appropriate number can be set as necessary, and the workpieces (1) to be handled can be set. The present invention is not limited to an engine valve, and can be applied to, for example, a cylindrical work or the like which is conveyed while rolling on a U-groove chute that inclines downward.

[0014]

[Effect of device]

 According to the device of the present invention, a large number of works transferred by the chute can be automatically put into a container or the like by a fixed number without manual intervention, so that the labor can be saved and the number of lots of works can be reduced. Management and the like can be performed easily and accurately.

Claims (1)

[Scope of utility model registration request] 1. A first selector device that alternately enters the lower end of a work transfer chute that inclines downward and an upper part that is separated by a predetermined number of works from the lower end, and that alternately enters the work transfer path by a control device. A second selector device is provided, and a sensor for detecting the presence or absence of the rearmost work stored in a predetermined number is provided at a position close to the second selector device, and the sensor detects the stop of the rearmost work. Thus, the second selector device is actuated to close the transport path, and at the same time, the first selector device is actuated while a predetermined number of works pass to open the transport path.
