Description

[Detailed Description of the Invention] This invention relates to a device for attaching and detaching an article in a one-touch manner, applying rotation to the attached article, and then releasing the article.

Generally, when products and articles such as bearings that are manufactured in large quantities are subjected to anti-corrosion treatment or cleaning treatment, the articles are placed in a basket and immersed in oil in a tank for a predetermined period of time, and then the oil is drained. Alternatively, a method has been adopted in which a part of the conveyor belt is submerged in oil, and the articles are carried by the conveyor belt, passed through the oil, and then drained.

However, in such conventional methods, oil and liquid are consumed more than necessary, which is one of the causes of increased running costs.

In addition, it takes time to drain the oil, especially when a conveyor system is used, resulting in problems such as very poor space efficiency.

In view of the above-mentioned conventional problems, this idea was developed by individually holding mass-produced items one by one, submerging them in rust-preventing oil, etc., then lifting them up and shaking them around in a tank. It was devised during the development of a series of robot devices that can shake off the objects, etc., and aims to provide a device that can pick up and rotate a large number of continuously sent objects by simply lifting and lowering the entire device.

In other words, this invention can withstand frequent repeated use several thousand to hundreds of times a day, smoothes and stabilizes the operation of attaching and releasing an annular article, and ensures quick and reliable operation. Objects are loaded and released using operating force.

In particular, the annular article skewered in the first case is securely clamped and fixed from above and below by a pressing member and a protruding member under the action of a spring at the outer periphery of the first case. The entire first and second cases are rotated by a rotation drive mechanism, and this rotation is reliably transmitted to the annular article from above and below through the clamping action of the pressing member and the protruding member.

Furthermore, in order to reduce the internal frictional force associated with the movement of the protruding member into and out of the protruding member, and to make the protruding member move in and out smoothly, and to smooth and stabilize the vertical movement of the inner core rod during the movement of attaching and releasing the annular article. In order to ensure speed and reliability, a thrust bearing is interposed to support the inner rod upward at a constant pressure.

The operation of this assembly consists of moving the support body 50 to the article loading position, lowering the entire body onto the article positioned in this position and inserting the first case body 1 into the article in a skewered manner; The protruding member 3 and the holding member 32 hold the article from above and below, and in this state, the whole article is moved to a processing position (such as a washing tank), immersed, pulled up, and rotated to shake off the processing liquid. After that, it is moved to the discharge position and discharged.

Attachment and detachment of the article is carried out by the first case and its related parts sliding up and down within the second case, causing the upper and lower clutch halves to engage, and as a result, the inner core ring moves up and down, causing the protruding member of the first case to engage. The protruding member appears inside and outside the case at the housing window,
One-touch attachment/detachment of a removable article having a hole or a hole.

The structure of the engagement pad for the upper and lower clutches when they are half-off is as follows.

That is, the upper clutch half-off 26 has clutch teeth 26 having two symmetrical inclined surfaces at positions 180° opposite to the lower end surface thereof.
at26b, and the lower clutch half 16 has clutch teeth 16a, 16b with four symmetrical inclined surfaces spaced at 90° intervals on its upper end surface.

16c and 16d, and the upper and lower clutches are half-off 2
6. On the outer peripheral surface of 16 are key grooves 26c having a predetermined length in the vertical direction and spaced at 180° intervals.

16e, and a key 18a that fits into the key groove is provided on the inner peripheral surface of the cylindrical inner member 18.

The length of this key 18a is an appropriate length that can hold the inner core ring B in the upper position and the lower position, and its lower end surface is
This is an inclined surface that meshes with the inclined surface of the clutch teeth on the upper end surface of the lower clutch half-rest 16.

In the illustrated state, the key 1° 8a is fitted into the keyway of the upper and lower clutch half-offs 26, 16, and in this state, the lower clutch half-off 16 integrated with the inner core ring B is connected to the cylindrical inner member 18. The projecting member 3 is in a so-called upper position, and is in a retracted state.

Furthermore, in this state, the upper and lower clutch teeth are slightly separated.

In this state, the support body 50 moves to the position where it grips the article.
, the lower end of the case body 1 hits the bottom of the article support stand, etc., and in this state, if the whole body is further pushed down by a slight amount via the support body 50, the first case body 1 is moved down to the second case body 1. The bullet 25 is compressed against the case body 22 and moves upward, and at this time, the lower clutch is half-off 1
The clutch teeth on the upper end surface of the upper clutch 6 come into contact with the clutch teeth on the lower end surface of the upper clutch half-off 26.

The actual movement is that while the first case body 1 is stopped in the state shown in the drawing, the second case body 22 is lowered downward, and the upper clutch half-off 26, which is integrated with the second case body 22, is moved downward. It will move downward.

At this time, the upper end of the first case body 1 and the cylindrical inner member 1
8, and therefore, the upper clutch half-closed 2 is in contact with the first case body 1 and the cylindrical internal coupling member 18
6 and the lower clutch half-off 16 remain in contact with each other and move downward while compressing the bombs 4 and 25, thereby causing the key 18a provided on the inner peripheral surface of the cylindrical inner member 18 to move the lower clutch half-off. As a result, the lower clutch half-off 16 becomes rotatable, and as a result, the clutch teeth of the lower clutch half-off 16 slide along the inclined surface of the clutch teeth of the upper clutch half-off 26.
Rotate 5 degrees.

Next, when the support body 50 is moved upward, since the lower clutch half-off 16 has been rotated by 45 degrees as described above, the key 18a on the inner surface of the cylindrical inner member 18 and the outer surface of the lower clutch half-off 16 are rotated by 45 degrees. It is different from the keyway 16e of
As a result, the lower end of the key 18a comes into contact with the top end of the clutch teeth on the upper end surface of the lower clutch half-rest 16, and due to the mutual contact of the inclined surfaces, the lower clutch half-rest 16 is again rotated by an additional 45 degrees in the same direction. In addition, the key 18a keeps the lower clutch half-off 16 moved downward, and as a result, the inner core ring B keeps the protruding member 3 protruding.

As a result, the lower surface of the article is supported by the protruding member 3,
It is pressed down from the top by a pressing member 32 via a bullet 34 to achieve firm attachment.

In this state, the component is carried to the processing position, immersed in the processing liquid, and pulled up, and the entire first and second case members are rotated relative to the support body 50 to shake off the processing liquid.

After that, it is carried to the ejection position, where the whole is lowered towards the ejection stand etc., and the second case main body 22 and the upper clutch half-off 26 are again moved against the first case 1 and the cylindrical inner member 18. is lowered, and both clutches 26, 16 are lowered while the clutch teeth on the lower end surface of the upper clutch half-off 26 are in contact with the clutch teeth on the upper end surface of the lower clutch half-off 16, and the lower end of the key 18a is the clutch of the lower clutch half-off. This causes the clutch teeth to mesh with each other while sliding along their respective inclined surfaces, thereby causing the lower clutch half-rest 16 to rotate by 45 degrees.

Then, when the support body 50 is moved upward,
This time, the lower end of the key 18a on the inner surface of the cylindrical inner member 18 hits the top surface of the next clutch tooth of the lower clutch half-off 16,
The lower clutch is half-off while sliding along each other's inclined surfaces 16
is further rotated by 45 degrees, whereby the key 18a fits into the keyway 16e on the outer periphery of the lower clutch half-off 16.

As a result, the lower clutch half-off 16 can be moved upward to the illustrated state, the inner rod B is maintained in a pulled-up state, and the protruding member 3 can be retracted.

Therefore, the attachment of the article is released.

The above operations are repeated.

Further, when the article is held, the article is stably held between the holding means and the protruding member.

As explained above, this invention is a device for attaching an annular article such as a bearing by moving a protruding member in and out, and releasing it after giving it rotation. The first case has a cylindrical shape that can be retracted and retracted, and a fifth latch and a half on the upper part are formed with clutch teeth and are connected to the output shaft of the rotational drive mechanism such as the motor. A second case that is freely supported, a clutch tooth that engages and disengages with the clutch tooth of the upper clutch half-off, and a key groove extending in the axial direction continuously from the tooth are formed to provide the L-J section clutch half-off. , a truncated conical part is formed at the lower end of which a protrusion appears and retracts, and is provided between the inner core rod which is pressed upwardly by the spring and the sliding plate of the inner core rod and the spring, and is provided between the inner core rod and the sliding plate of the inner core rod, and is A thrust bearing rotatably supports the core rod, and a key extending in the axial direction is formed on the inner peripheral surface, and is slidably inserted into the second case, and is always attached downward with a spring. At the same time, a sliding guide member fixed to the first case into which both clutch teeth engaging/disengaging parts are fitted, and a sliding guide member which is fitted onto the outer circumferential surface of the first case so as to be slidable in the axial direction, are attached. an annular article attachment/detachment mechanism consisting of a presser member that presses the article from above via a spring; a rotary support that rotatably supports a second case of the attachment/detachment mechanism; It is connected to the upper clutch half of the attachment/detachment mechanism and includes a rotational drive mechanism such as a motor that rotationally drives the second case, and the second case is rotated by contact between the first case and the article support stand, etc. By contracting and sliding the first case, the key of the sliding guide member is inserted into or engaged with the key groove or clutch teeth of the lower clutch, and the inner core rod is moved relative to the first case. The annular article is attached and detached by rotating and moving up and down to make the protruding member appear and disappear, and the attached annular article is rotated by the rotation drive mechanism via the attaching and detaching mechanism. This device is characterized by a device for holding, rotating, and releasing an annular article, in which a protruding member made of a steel ball and a holding member are used to securely and firmly hold an annular article skewered in a first case from above and below. Because of this, it is possible to attach and detach a large number of items.
As a rotating/releasing device, it has an extremely long life, and since these movements can be switched continuously using a simple latch mechanism, articles can be loaded and unloaded simply by lifting and lowering the entire device, reducing loading and unloading time. can be extremely shortened.

In short, the present invention can withstand frequent repeated use thousands to hundreds of times a day, smoothes and stabilizes the operation of attaching and releasing an annular article, and ensures quick and reliable operation, while requiring only a slight operating force. Items are loaded and released using the following methods.

In addition, the space required for the series of treatment processes of immersion in anti-corrosion oil, lifting, and oil removal can be reduced to a tank installation area with a very small flat area that allows one annular object to be inserted and immersed. The rotary oil movement is carried out on the spot to proactively and quickly remove oil, reducing oil consumption due to excess oil adhering to objects and carrying it away, reducing running costs and improving work efficiency. This was achieved through a combination of improvements.

Moreover, in the present invention, the annular article skewered in the first case is securely clamped and fixed from above and below by the pressing member and the protruding member under the action of the spring 34 at the outer periphery of the first case. In this state, the entire first and second cases are rotated by the rotation drive mechanism, and this rotation can be reliably transmitted to the annular article from above and below through the clamping action of the pressing member and the protruding member, This allows oil to be drained quickly and reliably, and in particular,
When holding an annular article, do not do it only at its upper end (
, the first case passes through the entire length of the annular article, and the annular article is securely clamped and fixed from above and below by a holding member and a protruding member, improving stability and safety during rotation. , it is possible to prevent adverse effects such as unbalance and vibration on the rotating support body, and furthermore, when releasing the held article, the annular article is moved by the presser member to the first position by the stored elasticity of the spring 34 acting on the presser member. It can be forced out of the case quickly and reliably.

The present invention also aims to reduce the internal frictional force associated with the movement of the protruding member into and out of the protruding member, so that the protruding member can smoothly move in and out, and to smooth the vertical movement of the inner core rod during the movement of attaching and releasing the annular article. In order to achieve stability and quick reliability, the inner core rod is supported upward at a constant pressure using a thrust bearing.

Furthermore, in order to prevent damage to the clutch teeth and the annular article, the present invention uses springs 4 and 25 to absorb the impact acting force when the first and second cases contract and slide. It is intended to be conveyed indirectly to the surface.

Furthermore, in order to quickly and reliably attach and release the annular article, the present invention provides a method for picking up the annular article that is placed in place (by the action of picking up the annular article and placing the attached annular article on a stationary table, etc.). The first case and the second case are slid relative to each other, and in the middle of this movement, the upper clutch teeth of the second case are lightly pressed against the lower clutch teeth under the retractable action of the spring 4. This prevents impact damage to the clutch teeth, and at the same time, separates the sliding plate of the inner rod from the bottom surface of the sliding guide member to reduce rotational friction. Furthermore, due to the presence of the thrust bearing, meshing rotation by the cam action of both clutch teeth is prevented. This makes the rotation of the inner core rod and the switching operation of the vertical position reliable and quick, and improves the function of controlling the protrusion and retraction of the protruding member.
The release is achieved easily and automatically, and moreover, with a very simple mechanism.

Then, by using the shaft at the upper end of the upper clutch, which is half-closed, this shaft is connected to the output shaft of a rotational drive mechanism such as a motor to give rotation to the entire attachment/detachment mechanism. The output shaft of the drive mechanism can be coupled with an extremely simple configuration, and the article can be reliably attached and detached even while the article is rotating. Since the mechanism can be installed using the dead space above the attachment/detachment mechanism, it does not take up much space, and it is easy to attach and detach the annular article, sink it into a rust-preventing oil tank, pull it up, drain the oil, etc. It has the advantage that it does not get in the way of transporting the annular article, and does not become a hindrance when moving the annular article back and forth between the carrying-in position, the submergence, lifting and rotation processing position, and the carrying-out position.

Furthermore, if it is used in the robot device that is immersed in anti-corrosion oil as described in the example, the anti-corrosive treatment and cleaning of the article to be treated can be carried out very smoothly and without manpower, and the quality of the treated items is constant. do.

It also eliminates unnecessary consumption of anti-rust oil, cleaning fluid, etc., and helps reduce running costs.

In addition, oil draining can be performed quickly and reliably, and the device can be configured extremely compactly, making it extremely effective and highly efficient.

Therefore, the present invention can provide a device for holding, rotating, and releasing an annular article suitable for use in anticorrosion treatment or cleaning treatment of products and articles such as bearings manufactured in large quantities. It is.
