As described above, various proposals have been made regarding the alignment of the shaft member, but the current situation is that the grease application to the shaft member has been performed manually. That is, the shaft members carried in the shaft member carrying basket are taken out one by one and greased with the brush. However, this method has the following problems.
(1) At least one dedicated person is required for the grease application process.
(2) It is necessary to handle heavy objects such as loading and unloading of the shaft member carrying basket.
(3) Grease application amount and application area variation (it is difficult to apply because it is applied all around. On the contrary, there are places where it is over-applied) and there are concerns about quality such as forgetting to apply (unpainted)
(4) Grease may be attached to places other than the place where it is planned to be applied.

  The inventors of the present invention diligently tried to solve the difficult problem of applying an adhesive that is difficult to handle without sticking out to a specific place on the pin-shaped object. As a result, it is found that the pin-like object starts to rotate by biting the stopper to the device for aligning the pin-like object, and if this rotation is used, the coating film is automatically averaged after applying the grease. The present invention has been completed.

  That is, the rotary coating apparatus according to the present invention is an apparatus for applying an adhesive coating to a pin-shaped object having a large-diameter head and a small-diameter trunk, and the coating apparatus includes a pair of Guide rails, vibration generating means for applying vibrations to the guide rails, and article stop means for stopping the pin-like article suspended between the guide rails and transported by vibrations at a specific position of the guide rails. And an application means for applying the adhesive coating to the pin-like object to be rotated by vibration at the time of stopping.

  Further, the rotary coating apparatus according to the present invention is, for example, as a coating film averaging means for leveling the adhesive coating applied to the pin-shaped object, It is preferable to provide baffle plates arranged in parallel.

  Examples of the pin-shaped object include a shaft that connects a frame body of a motorcycle and a main stand. Examples of the object-stopping means include a plurality of the pin-shaped objects to be continuously fed. There may be mentioned a stopper inserted between the objects, and the adhesive coating material may be grease.

  Further, the rotary coating method according to the present invention suspends the head of a pin-like object having a large-diameter head and a small-diameter body between a pair of guide rails provided with vibration generating means, and generates vibration. First step of transferring a specific number of pin-like objects to be transferred, the transferred pin-like object to be rotated is stopped at a specific position of the guide rail by an object stopping means, and at this stop, rotation is caused by vibration. The second step of applying a sticky coating to the pin-shaped coating material that has been started by the coating means and leveling the coating material by the coating film averaging means, and the pin-shaped coating material by uncovering the coating material stopping means Comprises a third step of sending the powder to the collecting means by vibration.

  By repeating the above first to third steps as appropriate, an adhesive coating can be continuously applied to a large number of pin-shaped coatings.

  According to the rotary coating apparatus and the rotary coating method of the present invention, it is possible to rotate the pin-shaped object to be stopped by combining the vibration generating means and the object stopping means. Therefore, using this rotation and coating film averaging means, it is possible to automatically flatten the coating film by the applied adhesive coating.

  Therefore, it is possible to improve the workability, save labor, and improve the quality by applying grease to the shaft member, which has been conventionally relied on manually, efficiently and only in the necessary portions.

  Next, an example of implementation will be described in detail with reference to the drawings. In the embodiment, the application to the shaft member for connecting the main stand of the motorcycle and the frame body will be described as an example, but the apparatus and method of the present invention are not limited to this example. In any field where an adhesive coating is applied to a pin-shaped object having a large-diameter head and a small-diameter body similar to the shaft member, the present invention can be used in any case.

  FIG. 1 is a perspective view of a shaft member applied by the coating apparatus of the present invention. The shaft member 100 includes a head portion 101 having a large diameter and a body portion 102 having a small diameter. Further, the body portion 102 is formed with an application portion 102a and an application portion 102b for applying grease. The application part 102a and the application part 102b have a depth of 1 to 1.5 mm, for example, and the application width is about 10 mm for the application part 102b and about 40 mm for the application part 102b.

  Next, the rotary coating apparatus according to the present invention will be described with reference to FIGS. Here, FIG. 2 is a plan view of the entire shaft member aligning apparatus incorporating the rotary coating apparatus, FIG. 3 is an overall plan view of the rotary coating apparatus, and FIG. 4 is applied to the adhesive coating by the rotary coating apparatus. It is a figure explaining the state.

  In the figure, reference numeral 1 denotes a shaft member aligning device. The shaft member aligning device 1 sequentially applies grease to a parts feeder 2 in which shaft members before application are randomly stored and a shaft member 100 delivered from the parts feeder 2. A rotary coating device 3 for coating, and a completed carriage 4 for preparing to send the coating-processed shaft members to the next process after being aligned and stored in a plurality of rows are connected to each other.

  The parts feeder 2 is provided with an oscillation device (not shown) as vibration generating means. After the shaft member is pushed into the tapered outlet of the part feeder-2, for example, 20 shaft members are operated, and the oscillation device is operated. The 20 shaft members are sequentially transferred to the rotary coating device 3 of the present invention by vibration.

  The rotary coating device 3 has a pair of guide rails 5, 5 continuous from the parts feeder 2, and the head 101 of the shaft member 100 is suspended between the guide rails 5, 5. The vibration generating means for applying vibration to the guide rail is also used as the oscillating device attached to the parts feeder 2 in the figure, but may be separately installed in the device.

  The shaft member 100 that has finished the step of vibrating and transferring with the guide rail (first step) then enters the second step of application / planarization step. When the shaft member 100 comes to a specific position, the shaft member 100 is detected by the sensors 6 and 6 and is stopped by the stoppers 7 and 7 which are the object stop means so as to be rotatable.

  Although the number of the stoppers 7 and 7 may be one, by using two as in this example, rotation by the vibration of the shaft member 100 retained between the stoppers is facilitated. Note that the number of shaft members 100 retained between the stoppers is preferably one or two for smooth rotation.

  In addition to the stoppers 7 and 7, stoppers 8 and 9 are further provided. When four shaft members 100 are accumulated in the stopper 8, for example, when the upstream shaft member 100 is locked by the stopper 9 and the stopper 8 is opened. The four shaft members 100 are transferred by vibration, and two are held between the stoppers 7 and 7 and further two are rotatably held on the upstream side of the stopper 7. Then, each of the four shaft members 100 can be smoothly rotated. In this way, grease, which is an adhesive coating, is applied to the four shaft members 100 that rotate smoothly.

  In order to apply grease to the application part 102a and the application part 102b of the shaft member 100, an appropriate amount of grease is sprayed from the application nozzle 10 which is an application means provided at a position opposite to each application part.

  By the way, it is advantageous in terms of nozzle maintenance if the application nozzle 10 of the same standard with a constant injection amount is employed. In such a case, application can be performed by the following procedure. That is, for example, 1 g of grease is spray-applied to all the four shaft members that are stationary and rotating on the wide application portion 102b with a large application amount, and the most downstream of the four is applied to the narrow application portion 102a. Similarly, apply 1 g of grease to only one of these. Then, the stoppers 7 and 7 are operated to move each shaft member by one, and the same 1 g coating is performed. By repeating this operation, the application part 102a can apply only 1 g of grease, and the application part 102b can apply a total of 4 g of grease by application four times.

  The grease applied to the shaft member (pin-shaped object) 100 is swelled due to viscosity, but since the shaft member 100 is rotating, the grease is leveled by the baffle plate 104 which is a coating film averaging means. It becomes. For this reason, when the shaft member 102 is attached to the motorcycle, it is possible to prevent the grease from protruding or forgetting to apply the grease. In addition, it is more effective if another baffle plate 104 is attached to the application nozzle 10 side so as to sandwich the shaft member.

  The shaft member 102 that has completed the application and averaging of grease in this manner is heated to some extent if necessary, and the stopper 6 is released, and the third step is completed by sending it to the complete carriage 4 as a collection means by vibration. By repeating these first to third steps as appropriate, it is possible to apply grease to a large number of shaft members 102 accurately and quickly.

  The spin coating apparatus and spin coating method of the present invention can easily apply an adhesive coating such as grease, which has been difficult to accurately apply to small parts, so that bolts, nails, various pins, etc. It has a large-diameter head and a small-diameter body as described above, and can be suitably used in automobiles, architecture, and various machine industries where an adhesive coating must be applied.
