Abstract

PURPOSE:To improve the feeding efficiency of such parts as rubber or the like being poor in slidability, by constituting a track, having a parts dropout preventive wall, in a way of turning it around a disc whose surface is made so slippery, in case of a rotary type parts feeder. CONSTITUTION:A disc 3 maximizes the thickness of a part of a rotary shaft setting hole 30 and reduces the thickness toward its outer circumference by degrees, forming a sectional umbrella shape, while installs plural grooves 31 radially out of the hole 30. Each form of these holes 31 should be selected in a manner conformable to fed parts. With this constitution, if the disc 3 is rotated, feed parts receives centrifugal force and move to the outer circumference. At this time, owing to the presence of these grooves 31, friction between each part and the disc 3 is being reduced, whereby they are smoothly move to the outer circumference with the help of the umbrella form of the disc 3, and transferred onto a rotating track 1 at a transfer point 6, then transferred. Thus, even in case of soft parts such as rubber or the like, they are smoothly feedable and, what is more, feeding efficiency is improvable.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the supply of parts, and relates to an improvement of the supply machine described in Patent No. 1,129,756 owned by the applicant.

The supply of parts for automation and labor saving has come to be used not only in the fields of electrical and mechanical industries, but also in industrial fields such as the chemical industry, rubber, and plastics. For this reason, it has become necessary to supply and align not only conventional hard parts but also soft rubber, plastic, and other products.The present invention meets the demands of such a wide range of industrial fields. .

Conventional technology Since soft parts such as rubber and plastic absorb vibrations, they cannot be fed at all by the vibrating parts feeder that has been widely used in the past.
Even in the revolving type parts feeder described in No. 6, the parts to be fed cannot move smoothly on the disk, so it is currently very difficult to align the parts. Even in the case of hard parts to be supplied, the friction with the surface of the disc is large and the slippage is poor, making it difficult to align the parts to be supplied.

Problems to be Solved by the Invention In a revolving type parts feeder, it is essential to smoothly transfer the parts to be fed from the disk to the track in appropriate amounts in order to improve the efficiency of aligned feeding. The parts to be supplied are moved to the outer periphery of the disc by the centrifugal force caused by the rotation of the disc and transferred to the truck, but when the parts to be supplied have relatively large friction with the disc, Since the friction is large, it will not start moving unless it receives a large centrifugal force.
When it begins to move, it is moved toward the outer periphery by a strong force, and many of the parts to be supplied are bundled into the truck or collide with the alignment wall, which only reduces the efficiency of supply. Otherwise, the supplied parts may be damaged.

Means for solving the problem In order to solve the problem caused by the large friction between the disc and the supplied part, it is necessary to improve the condition of the surface of the disc where the disc comes into contact with the supplied part. It must have a smooth structure.

The invention will be explained by examples.

FIG. 1 is an explanatory diagram of the structure of a rotating parts feeder for carrying out the present invention. A disk 3 rotated by a shaft 5 is in contact at a point 6 with a track 1 rotating around the outer circumference of the disk 3. A drop-off prevention wall 2 made of a part of a spherical surface is fixed to the lower part of the track 1, and the drop-off prevention wall 2 comes into sliding contact with the outer periphery of the disk 3 over the entire circumference. The bottom of the fall prevention wall 2 is connected to a motor (not shown) via an annular member 4, and the truck turns. Since the direction of the central axis of rotation of the truck and the direction of the rotational axis of the disk have a certain inclination, the surface of the track is always above the surface of the disk.

FIG. 2(a) is an explanatory diagram of a disk 3 for implementing the present invention, and FIG. 2(b) shows its cross section. There is a hole 30 in the center of the disk 3 for attaching the rotating shaft 5, and the disk is formed into an umbrella shape, with the hole 30 having the maximum thickness and becoming thinner toward the outer periphery of the disk 3. one or more grooves 31 on the surface of
are provided radially around the hole 30. The cross-sectional shape of the grooves 31 and the interval between the grooves are selected depending on the parts to be supplied. It does not change the spirit of the present invention to form the umbrella-shaped surface of the disk 3 with a net instead of the groove 31.
It is an explanatory view when the disk shown in the figure has a trapezoidal cross section. There is a flat circular part 32 around the center hole 30,
There is an inclined part around the circular part 32 up to the outer periphery of the disk 3, and one or more grooves 31 are provided radially in the inclined part corresponding to the parts to be supplied. Formed with a net on the slope part vIt31
This does not change the spirit of the present invention. The grooves and mesh surfaces described here are means for reducing friction with the supplied parts, and the surface of the disk 3 provided with these means is called a smooth surface.

FIG. 4 is a sectional view of the explanatory diagram in FIG. 1 with the implementation of the present invention added, and shows the point of contact between the disc 3 and the track 1 (this is called the transfer point) and the turning axis of the track. A sliding plate 34 having a large number of ventilation holes 35 on the entire surface of the disk 3 is attached to the top of the disk 3, and the ventilation holes 35 connect the front and back sides of the sliding plate 34 and extend from the back surface to the front surface. Air can freely flow in and out. The shaft 5 of the disk is formed by a rotating tube 43, and a rotating joint 42 having an air supply port 41 at the bottom is attached.
4 has an opening 44 that opens into an empty cup 45 formed on the back surface of 4. Air supplied from the air supply port 41 passes through the rotary joint 42 and the rotary tube 43, flows into the air cup 45 from the opening 44, and is blown out from the vent 35 onto the surface of the sliding plate 34.

FIG. 5 is an explanatory diagram of the sliding plate 34, which has many ventilation holes 35.
Indicates the state in which the The shape, number and distribution of the vents are manufactured according to the parts to be supplied.

FIG. 6 is an explanatory diagram of the main parts of a device for supplying air from above the disc for the action shown in FIG. is fixed, and the rotary joint 53 is fixed to the sliding plate 34, and the rotary joint 5
The opening 54 of No. 3 connects the air supply pipe 52 to the 0-rotation joint 53 which is open in the empty cup 45, and allows air to flow in from the air supply port. Omitting the rotary joint 53 by rotatably attaching the air supply pipe 52 to the sliding plate 34 does not change the spirit of the present invention.

In Fig. 7, instead of allowing air to flow into the rotating part explained in Fig. 4, a ventilation hole 35 is provided in one disc 3, and a nozzle 46 is fixed to the lower side of the disc inside the transfer point. It does not change the spirit of the present invention to direct the opening on the 0 ventilation day toward the outer periphery of the disk so that the direction in which air flows out is in the direction of the outer periphery of the disk.

Operation The operation will be explained with reference to FIGS. 1, 2, and 3. The parts to be supplied are put onto the disk 3 and stored therein. 6 In the present invention, where the disk 3 has a smooth surface, the parts to be supplied are stored on the smooth surface. The disk 3 is rotated via the rotating shaft 5 by a motor (not shown), and the parts to be supplied also rotate, so that the parts to be supplied are subjected to centrifugal force. This centrifugal force overcomes the friction acting between the supplied part and the disk and moves toward the outer periphery, and is transferred from near the transfer point 6 via the member 4 to the truck l, which is rotated by a motor (not shown). Ru. However, the parts to be supplied made of soft rubber, soft plastic, etc. have large static friction, and if the rotation of the disc 3 is made faster, it will not start moving, but it will start moving: Static friction turns into kinetic friction, and sometimes it is blown away. , the truck transfers at high speed and crashes into an alignment wall.

In the present invention, the supplied part is placed on the smooth surface with the groove 31.
□The parts to be supplied are placed between the grooves 31 and 31.
□Since it is supported by the convex part, friction is reduced and the groove 3
Direction 1 is made radially from the center to the outer periphery.・
The supplied parts cannot move in the rotational direction because
;Easy to move only in the outer circumferential direction. I wanted to
”In the present invention, it is possible to slow down the rotation of the disk.
゛Since the supplied parts are only subjected to a small centrifugal force, they are transferred from disk 3 to truck 1 at low speed □
Become. The operation will be explained using the embodiment shown in FIGS. 4 and 5. An air pressure source (not shown) is connected to the air supply port 41 and air is fed under pressure to the rotary tube 43 via the rotary joint 42 . The disk 3 is rotated via a rotating shaft 5 by a motor (not shown).

Is the rotating tube 43 connected to the rotating shaft 5 rotating with the rotating shaft 5?The air supply port 41 is fixed to the rotating joint 42 attached to the rotating shaft 5, so the zero-rotating tube 43 does not rotate. The flowing air flows into the empty cup 45 through the opening 44 and uniformly flows out onto the surface of the sliding plate 34 through the vent 35 provided in the sliding plate 34. Since the parts to be supplied are placed and stored on the sliding plate 34, they are lifted from below by the air flowing out from the vent 35, and the friction between the sliding plate 34 and the parts to be supplied is extremely reduced. Since the sliding plate 34 is made in an umbrella shape, the parts to be supplied are moved to the sliding plate 34 by gravity.
The vehicle is moved to the outer periphery of the disk 3, that is, the outer periphery of the disk 3, and is quietly transferred to the truck 1. In order to facilitate the transfer of supplied parts to the truck l, ventilation holes are provided radially on the outer periphery of the sliding plate 34 to allow air to flow out radially as well, thereby assisting the transfer of supplied parts onto the truck. It does not change the purpose. In addition, the ventilation hole 35 provided in the sliding plate 34 is connected to the sliding plate 34.
It does not change the spirit of the present invention to open the opening toward the outer periphery of the opening. It is also within the spirit of the present invention to fix the rotary joint 53 to the sliding plate 34 as shown in FIG. It's not something you can replace.

The embodiment shown in FIG. 7 is a simplified version of the embodiment shown in FIG. 4, and a large number of ventilation holes 35 are installed in the disc 3 and fixed to a member (not shown) below the disc 3 near the transfer point. Nozzle 46
When the supplied parts stored on the disk 3 approach the transfer point 6, the air flow from the nozzle 46 reaches the disk 3.
This makes it easier to push up the supplied parts and transfer them to the truck 1 through the vent hole 35 opened in the upper part. Providing a nozzle below near the center of the disk 3 for moving the parts to be supplied at the center to the outer periphery of the disk 3 does not change the spirit of the present invention.

Example: When supplying parts coated with oil for lubrication in an aligned manner, the contact area of the parts to be supplied with the disc is wide, and the gap between the parts to be supplied and the disc is filled by the oil. The parts were in close contact with the disc and could not be fed using a normal feeder. According to the present invention, feeding can be easily realized by providing a groove on the disk and rotating the disk. When manufacturing the feeder, it was easier to attach a net over the disc 3, so when the net was used for feeding, the same effect as with the groove was obtained.

In a case where jelly for lubrication was applied to a supplied part made of a rubber foil screen, the method shown in Fig. 4 was carried out. The sliding plate was made of a fine wire mesh, and low-pressure air was supplied from a blower. Air was blown out from the mesh of the wire mesh and lifted the parts to be supplied from the disc, so that the parts to be supplied could be easily transferred to a truck. Also, although air is blown out from the portion of the wire mesh where the parts to be supplied are not placed, the amount of air blown out is small and does not have much of an effect on the air pressure acting on the parts to be supplied. Blowing a small amount of air from the center of the disc toward the transfer point assists in the movement of the parts to be supplied, and is therefore beneficial in increasing the efficiency of supply.

Effects of the Invention The present invention not only facilitates the automatic feeding of sticky parts, which have traditionally been difficult to automatically feed, but also
Automatic supply is effective for supplying parts that were thought to be impossible, especially thin and soft rubber and plastics, and can contribute to the rationalization of industrial fields that were previously thought to be impossible to automate, improving the production process. The contribution to automation 1 rationalization is extremely large.
