Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts take-out apparatus suitable for use in a work place where a large number of parts are used, such as an automobile assembly plant.

[0002]

2. Description of the Related Art Among parts, punched parts and small items such as bolts and nuts are accommodated in a hopper in a predetermined amount, and a necessary amount is taken out from the hopper and used for assembly. When the parts loaded in the hopper or the like are automatically taken out from one place as described above, the parts always stick to each other and a bridge phenomenon occurs. When the bridging phenomenon occurs, especially when the component is taken out upward from the hopper, the mountain of the component cannot be collapsed and becomes a concave shape, and it becomes impossible to take it out further.

As a technique for solving this problem, what has heretofore been generally performed is to give vibration to the entire hopper, or to swing the side wall and bottom of the hopper. That is, it is intended to separate the joined parts due to a shock due to vibration or a change in the center of gravity when rocked. This method is suitable when the parts are mainly small and cylindrical or spherical, or when they are powders or the like, but may not necessarily work well for parts having other shapes.

In order to promote automation, the automatic supply of parts is an absolute condition, and minimizing the number of times of replenishment will enhance the effect of automation. The larger the stock amount of parts in the hopper, the better. However, if the stock amount is increased, the chances of bridging the parts increase, and the following problems occur.

[0005]

In the case of a pressed product or the like in which the parts have a complicated shape, the bridge is not broken even if the hopper is vibrated or swung. Therefore, if the vibration or swinging power is increased in order to break the bridge, an excessive force is applied to the component, which may deform the component or damage the component. Also, as the size of the parts increases, the power for swinging the hopper also increases, and the device itself becomes larger and more complicated, and along with that, the rigidity of the hopper must be increased. Will be. Furthermore, although the method of giving vibration using a vibrator or the like is simple, noise increases as the size of the component increases, and it becomes difficult to arrange a plurality of units. In addition, it is necessary to take safety measures against the jumping of parts that occurs when vibration is applied.

The present invention seeks to provide a device for taking out parts which solves many of these problems.

[0007]

As a means for solving the above problems, the present invention provides a pedestal with a hopper for accommodating components, a chute near the hopper, and a horizontal chute near the chute. A movable actuator is provided in two directions, a vertical direction and a vertical direction, a supporting member is attached to one of the actuators that moves in the vertical direction, and an electromagnet for adsorbing the component is attached to the supporting member. is there.

[0008]

With this structure, the position of the electromagnet can be freely changed by the actuator, so that the actuator is reciprocated between the hopper and the chute,
By carrying out the power supply to the electromagnet in a timely manner, it becomes possible to surely move the parts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 1 is a mount, which is formed by welding angle members to form a frame. The lower part of this gantry 1 is fixed to the floor of the factory by anchor bolts or the like. A hopper 2 for accommodating components (workpieces) is provided from the upper part to the inside of the gantry 1. Items indicated by reference numeral 3 are parts. A chute 4 is provided above the gantry 1 in the vicinity of the hopper 2.
Parts 3 taken out from the hopper 2 by the structure described later
Is sent to a component aligning device (a device for aligning the postures of the components 3 taken out from the chute 4), which is provided outside the gantry 1 and is not shown.

A plate 5 is erected on a part of the gantry 1, and a first actuator 6 which supports a movable part (not shown) movably in the horizontal direction (Y direction) is supported on the plate 5. Has been done. The first actuator 6 is composed of a rail portion 7 that guides a movable portion and cylinders 8 and 9 provided at both ends thereof. When the cylinders 8 and 9 receive a predetermined signal, the rail portion 7 The movable portion supported by the portion 7 is moved by a predetermined amount in the horizontal direction indicated by an arrow in the figure.

The rail portion 11 of the second actuator 10 is fixed to the movable portion of the first actuator 6.
This second actuator 10 is also the first actuator 6
Similarly, the cylinders 12 and 13 are provided at both ends of the rail portion 11, and when the cylinders 12 and 13 receive a predetermined signal, the movable portion supported by the rail portion 11 is indicated by an arrow in the figure. Is moved in the vertical direction (Y direction) by a predetermined amount. The second actuator 10 constitutes a pick and press together with the first actuator 6.

A support member 14 is attached to the movable portion of the second actuator 10, and an electromagnet holder 16 is attached to the support member 14 via a rod 15 provided along the rail portion 11. ing. The electromagnet holder 16 is a rectangular one having a notch 17 at its tip, and a rod 15 penetrates its base. A U-shaped bracket 18 that opens downward is attached to the lower end of the rod 15, and this bracket 18 has a pin 1 that is bridged over the opening of the bracket 18.
9, through the hook 20 suspended on this pin 19, the component 3
An electromagnet 21 for taking out is attached. Reference numeral 22 denotes an electric wire for energizing the electromagnet 21, which passes through a hole 23 provided in the rod 15 and reaches an electromagnet 26 described below.

A notch provided at the tip of the electromagnet holder 16
A pin 24 is bridged over the pin 17, and the upper end of the chain 25 is locked to the pin 24. At the lower end of the chain 25, an electromagnet 26 for suspending the mountain of the component 3 is suspended. Since this electromagnet 26 is suspended by the chain 25,
It can move back and forth, left and right, and within 360 degrees between them.
On the other hand, since the electromagnet 21 described above is suspended by the hook 20, it can move only in the direction intersecting with the pin 19.

The operation of the device thus constructed is
This will be described with reference to FIGS. 2 and 3. Cylinder 8, 9, 1
By applying hydraulic pressure or pneumatic pressure to 2 and 13, the first and second actuators 6 and 10 are appropriately operated so that the two electromagnets 21 and 26 are both positioned above the hopper 2 (see FIG. 2). (Refer to the part indicated by the solid line). When the electromagnets 21 and 26 are lowered in this state, the component 3 is
, The first and second actuators 6 and 10 are actuated again to raise them, and they are moved to the right in the figure by the distance S, and when the movement is completed, the electromagnets 21 and
Turn off power to 26. Then, the component 3 attracted to the electromagnet 21 falls on the upper part of the chute 4 provided outside the hopper 2, and travels through the chute 4 to the next step, for example, the above-mentioned component aligning device.

On the other hand, when the component 3 attracted to the electromagnet 26 is moved rightward in the figure by the distance S by the first actuator 6, the distance between the first and second actuators 6 and 10 becomes the movement distance S. By setting the same value, it moves to the place where the electromagnet 21 was at the first stage. When the energization is cut off here, the peak of the component 3 in which the bridge phenomenon has occurred is destroyed and the component 3 is moved to the right. By repeating this operation, the bridge of the component 3 is destroyed, and thus the component 3 can be smoothly carried to the chute 4 side. In this case, since the electromagnet 26 is suspended by the chain 25, the electromagnet 26 fits well on the uneven surface of the mountain-shaped component 3 and is easily attracted, and the bridge is easily broken.

FIG. 3 shows the movable range of the electromagnet 26 with respect to the first actuator 6. As shown in the figure, the electromagnet 26 moves a distance a, a '. Therefore, if the amount of movement is controlled so as to change, the collapse of the bridge phenomenon becomes easier. Therefore, the rail portion 7 of the first actuator 6
A stroke detection sensor 27 is attached to the to detect the movement of the second actuator 10. As the type of the stroke detection sensor 27, various types such as electric type, mechanical type and optical type can be considered, and the mechanism includes contact type, non-contact type and the like.

In a control device (not shown), the central portion of the rail portion 11 of the second actuator 10 is controlled so as to stop at several points at an arbitrary stroke detection sensor 27. Thereby, the carry-out by the electromagnet 21 and the electromagnet 26
The landslide due to will be effectively performed. As in this embodiment, the cylinders 8 and 9 are attached to the first actuator 6.
When using, the stroke detection sensor 27 is preferably set to a predetermined position and controlled to repeatedly stop.

In the embodiment described above, the cylinders 8 and 9 are used for the first and second actuators 6 and 10, but the present invention is not limited to this. Other means,
For example, it is possible to use an electric motor or the like.

[0019]

As described above, the present invention is a device for taking out a component constructed as described above. Therefore, an electromagnet provided for breaking up a mountain of a component attracts the component from several points and lifts the bridge. Becomes fragile where the bond is weak. It may not be preferable to supply a large amount of parts at one time due to the parts aligning device installed in the latter part of the parts picking device, but the bridge is destroyed in the hopper, so that a large amount of parts Can be prevented from solidifying and solidifying and being taken out. As a result, it becomes possible to automatically and smoothly take out the parts put in the hopper to the end.
