Description

The present invention relates to a flanged component delivery control device that feeds flanged components one by one.

Hereinafter, in the present specification and claims, a flanged part may be simply referred to as a nut.

Japanese Unexamined Patent Publication No. 2007-320769 describes a mechanism for feeding out flanged nuts arranged in an inclined transport passage one by one.

JP-A-2007-320769

In the technique described in the above patent document, when the flange overlaps the flange of the adjacent nut, the upper part of the nut is pressed against the ceiling surface of the transport passage, and the nut is clogged. Good transport is achieved when the nuts are lined up in an orderly manner, but if impurities such as iron scraps intervene in the nut row or some vibration acts on the nut, the flange will be the flange of the adjacent nut. The phenomenon of riding on top occurs.

The present invention has been provided to solve the above-mentioned problems. Until the flanged parts are sent out one by one, a sufficient degree of freedom is given to the arrangement state of the parts, and the parts are clogged in the transport passage. The purpose is to correct the parts that have been united through the regulating member to a transport posture suitable for the next transport passage.

The invention according to claim 1
The transport passage for flanged parts is composed of a flange passage part and a part body passage part.
The spatial height of the flange passing portion seen in the thickness direction of the flange is defined as the height at which the flanges of adjacent parts can pass in an overlapping state.
The first regulating member that receives the first flanged part and the second regulating member that receives the second flanged part are arranged so that they can move forward and backward with respect to the transport passage.
It is a delivery control device for flanged parts, characterized in that an inclined surface for lowering the space height of the flange passing portion to a height at which overlapping flanges cannot pass is provided on the bottom surface portion of the flange passing portion.

The spatial height of the flange passing portion as seen in the thickness direction of the flange allows smooth passage through the flange passing portion even if the flanges of adjacent parts overlap. Therefore, even if the flanges overlap, parts will not be clogged, and the nut can be normally regulated by the first regulatory member and the second regulatory member, and is highly reliable. Transmission control can be secured.

The nut sent out with the first regulating member retracted and only one must be smoothly transferred to the next transport passage such as the supply hose. It is important for smooth transfer to maintain a normal transfer posture so that the flanges do not tilt or overlap by lowering the space height of the flange passage part to a height that does not allow overlapping flanges to pass through. Become. For this reason, the inclined surface for reducing the displacement allowance (movement allowance) of the flange at the flange passing portion, that is, lowering the space height of the flange passing portion to a height at which overlapping flanges cannot pass, is the flange. It is provided on the bottom surface of the passing portion.

When transporting parts by injecting air, it is important to increase the air pressure on the parts to increase the transport thrust, and it is required to reduce the gap between the inner surface of the passage such as the supply hose and the surface of the parts. To. Since the inclined surface is provided on the bottom surface of the passing portion, the above-mentioned small gap is formed in the supply hose or the like, and the strengthening of the transport thrust is achieved.

Until only one part is delivered, care should be taken to prevent clogging of parts during the transportation of many parts, and after the delivery of only one part, the transport posture of the parts should be corrected, and then the parts should be transported. Smooth transition to the transport passage.

It is sectional drawing of the whole apparatus and sectional view of a part part.

Next, a mode for implementing the delivery control device for the flanged component of the present invention will be described.

FIG. 1 shows an embodiment of the present invention.

First, the flanged parts will be described.

Various flanged parts that are subject to delivery control include distance pieces with integrated circular flanges, hexagonal projection nuts with integrated circular flanges, and tubular parts with flanges. There is. Here, it is a hexagonal projection nut with a circular flange integrated.

The projection nut 1 is provided with a screw hole (not shown) in the center of the hexagonal nut body 2 which is a component body. The circular flange 3 is integrally formed with the nut body 2, and three welding protrusions 4 are formed on the lower surface thereof at intervals of 120 degrees.

Next, the parts supply pipe will be described.

The component supply pipe 5 having a transport passage has an elongated cover plate 7 fixed to a long groove member 6 having a U-shaped cross section by bolting or the like. As shown in FIGS. 1B and 1C, the cover plates 7 arranged on the left and right are arranged in parallel. With such an arrangement, a flange passing portion 8 through which the flange 3 passes and a component body passing portion 9 through which the nut body 2 passes are formed. The component body passing portion 9 is composed of a space portion between the covering plates 7 arranged on the left and right sides. The component supply pipe 5 is tilted so that the left side is lowered so that the nut 1 can slide down.

The spatial height H1 of the flange passing portion 8 as viewed in the thickness direction of the flange 3 is a height at which the flanges 3 of adjacent parts can pass in an overlapping state. The thickness of the flange 3 is indicated by reference numeral H2. The space height H1 is larger than twice the thickness H2.

The nut 1 sent from the parts feeder 11 is conveyed to the parts supply pipe 5.

Next, the regulating member will be described.

The first regulating member 12 enters the transport passage from below and receives the flange 3 of the earliest nut (the earliest nut) 1. An air cylinder 14 is fixed to a support member 13 fixed to the lower surface of the groove member 6, and a piston rod or rod-shaped member thereof constitutes the first regulation member 12. The first regulating member 12 projects from the center of the passage width of the flange passing portion 8.

The second regulating member 15 enters the transport passage from above and receives the nut body 2 of the second nut (second nut) 1. The air cylinder 17 is fixed to the support member 16 fixed to the lateral side surface of the groove member 6, and the piston rod or rod-shaped member thereof constitutes the second regulation member 15.

Next, the inclined surface will be described.

An inclined surface 19 for lowering the space height H1 of the flange passing portion 8 to a height at which the overlapping flanges 3 cannot pass is provided on the bottom surface portion 20 of the flange passing portion 8. The lowered spatial height is indicated by reference numeral H3. The inclined surface 19 is formed on the wake side of the first regulating member 12.

The distance from the first regulating member 12 to the start of the inclined surface 19 is about one nut. Because of such a distance, the nut 1 that has passed through the first regulating member 12 immediately starts to climb the inclined surface 19, so that even if the subsequent nut 1 moves, the flange 3 does not overlap.

Next, other structures will be described.

When the nut 1 reaches the space height H3, the amount of movement in the vertical and horizontal directions is limited to a small amount, and the nut 1 is sent to the supply hose 21 in that state. The supply hose 21 is made of a synthetic resin such as polypropylene, and its passage cross section is the same as the shape shown in FIG. 1 (C) and is shown in FIG. 1 (E). The amount of movement of the nut 1 in the vertical and horizontal directions is limited to a small amount. The supply hose 21 is joined to the component supply pipe 5 by the joint member 22 having a square cross section.

Air is injected into the nut 1 that has passed through the first regulating member 12 and is sent to the supply hose 21 vigorously. The air injection pipe 23 directed to the nut 1 is fixed to a stationary member 24 such as the machine frame of the device.

The component supply pipe 5 is fixed to the stationary member 24 via the support member 10.

The component in the above embodiment is a nut with a flange, and a dome-shaped nut in which a hemispherical lid member 25 is welded to such a nut 1 as shown in FIG. 1D is targeted for delivery. Is also possible.

Next, the operation of the device will be described.

FIG. 1A shows a state in which the first regulating member 12 protrudes into the transport passage, receives the flange 3 of the frontmost nut 1, and the second regulating member 15 retracts and stands by outside the transport passage. ..

Then, when the second regulating member 15 advances by the operation of the air cylinder 17 and the first regulating member 12 retracts before and after that, the frontmost nut 1 slides down the component supply pipe 5 with only one nut 1. The second nut 1 is restrained from advancing by the second regulating member 15.

The independent frontmost nut 1 slides down the inclined surface 19 to reach the lowered space height H3, and is directly sent to the supply hose 21 by the injected air from the air injection pipe 23 to reach the target location (the target location (). It is sent to (not shown).

After that, when the second regulating member 15 retracts at the same time as the first regulating member 12 advances, the second nut 1 is received by the first regulating member 12 and becomes the first nut 1. Immediately after the second nut 1 advances, the second regulating member 15 advances to prevent the subsequent nut advance.

In addition, instead of the above-mentioned various air cylinders, an electric motor that outputs forward and backward can be adopted.

The above-mentioned operations such as advancing / retreating operation of each air cylinder and air injection can be easily performed by a generally adopted control method. A predetermined operation can be ensured by combining an air switching valve that operates with a signal from a control device or a sequence circuit, a sensor that emits a signal at a predetermined position of an air cylinder and transmits the signal to the control device, and the like.

The effects of the examples described above are as follows.

Even if the space height H1 of the flange passing portion 8 viewed in the thickness direction of the flange 3 overlaps the flanges 3 of adjacent parts, the flange passing portion 8 can be smoothly passed. Therefore, even if the flanges 3 overlap, the nut 1 can be normally regulated by the first regulating member 12 and the second regulating member 15 without causing clogging of parts. Highly reliable transmission control can be ensured.

The nut 1 delivered with the first regulating member 12 retracted and only one is required to smoothly move to the next transfer passage such as the supply hose 21. By lowering the space height H1 of the flange passing portion 8 to a height at which the overlapping flanges 3 cannot pass, it is smooth to maintain a normal transport posture so that the flanges 3 do not tilt or overlap. It is important for transportation. Therefore, the displacement allowance (movement allowance) of the flange 3 in the flange passing portion 8 is reduced, that is, the space height H1 of the flange passing portion 8 is lowered to a height H3 through which the overlapping flanges 3 cannot pass. An inclined surface 19 for the purpose is provided on the bottom surface portion 20 of the flange passing portion 8.

When transporting by injecting air into the nut 1, it is important to increase the air pressure with respect to the nut 1 to increase the transport thrust, and to reduce the gap between the inner surface of the passage such as the supply hose 21 and the surface of the nut. Is required. Since the inclined surface 19 is provided on the bottom surface portion 20 of the passing portion, the above-mentioned small gap is formed in the supply hose 21 and the like, and the strengthening of the transport thrust is achieved.

Care is taken to prevent component clogging in the transportation of many parts until only one nut 1 is delivered, and after the nut 1 is delivered with only one nut 1, the transport posture of the nut 1 is corrected. Then, the transition to the next transport passage is smooth.

As described above, according to the apparatus of the present invention, until the flanged parts are sent out one by one, a sufficient degree of freedom is given to the arrangement state of the parts to prevent the parts from being clogged in the transport passage, and the regulating member. The parts that have become one after the above are corrected to the transport posture suitable for the next transport passage. Therefore, it can be used in a wide range of industrial fields such as a body welding process for automobiles and a sheet metal welding process for home appliances.
