Abstract

PURPOSE:To aim at increasing the supply capacity of a part feeder with low noise, by provid ing such an arrangement that a rotary disc and a rotary peripheral wall are independently rotated around their respective axes while they are inclined such that the outer peripheral edge of the rotary disc and upper edge section of the rotary peripheral wall about on each other at one point, and a guide member is provided to form a part conveying gap along the upper edge section of the peripheral wall. CONSTITUTION:When part A is introduced into a recess 4 in a rotary container 3, the part A is set on a rotary disc 1 and are then moved to the outer peripheral section of the disc 1. Further, the part A is shifted onto the upper edge section 20 of outer peripheral wall 4a of the container at the position B where the the outer peripheral edge of the disc 1 abuts on the the upper edge part 20, and is liable to move diametrically outward. However, the head section of the part A falls in such a condition that it rides on the engaging stepped part 26 between the upper edge section 20 from further moving outward while the shank of the part A fitted into a part conveying gap 21 defined between the upper edge section 20 and the guide member 22. Thereby the part A is rolled and moved to a discharge section 20 along the guide member 22 in such a condition that the head section of the part A is engaged with and suspended by the upper edge section 20 and the engaging stepped part 26, and the shank thereof takes a stand-up posture, thereby it is possible to stably convey parts with no noise.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a parts feeder, in which parts having heads and shafts such as screws and rivets are arranged and fed in an upright state with the heads facing up. Conventionally, a vibrating parts feeder has been generally used as a parts feeder for aligning and feeding screws M''F.Also, when feeding parts in an upright state, this type of parts feeder is commonly used. A vibratory parts feeder is used that is connected to a pair of guide rails that engage both sides of the head of the parts.In other words, the guide rails hold both sides of the head of the parts transferred by the vibrating parts feeder. The device is configured to be fed in an upright state with the head facing upward by holding the device together and allowing the shaft portion to hang down.

(Problem to be solved by the invention) However, the above-mentioned vibrating parts feeder uses
Since it uses vibration, there is a problem that it is loud and the conveyance capacity changes even with small voltage fluctuations.
Furthermore, the maximum supply capacity is about 800 pieces per minute, which is a problem in that the supply capacity is small.

The present invention solves the above conventional problems and protects parts.
The object of the present invention is to provide a parts figure that can be quietly transferred to other ships by adjusting Vl+ according to circumstances, has a large supply capacity, and has little fluctuation in supply capacity due to voltage fluctuations.

(Means for Solving the Problems) The parts feeder of the present invention is provided with a rotating disk and a rotating circumferential wall in which the rotating disk can be placed, and the outer circumferential portion of the rotating disk and the upper end edge of the rotating circumferential wall are at one point. A rotary disk is disposed at a 411 angle inclination within a rotating circumferential wall so that the rotating disk and the rotating circumferential wall are substantially in contact with each other, and the rotating disk and the rotating circumferential wall are rotated independently about their respective axes in a relatively inclined state. The invention is characterized in that a guide member is fixedly arranged along the upper edge of the rotating peripheral wall so as to form a parts conveyance gap therebetween.

(Function) Since the present invention has the above-described configuration, when parts are thrown into the rotating peripheral wall, the parts are placed on the rotational disk and move radially outward due to the centrifugal force caused by the rotation, and each The parts are transferred to the upper edge of the rotating circumferential wall in sequence from the position where the outer circumferential edge of the oral disc and the upper edge of the rotating circumferential wall almost touch, and then the parts are transferred to the parts whose shafts are between the upper edge of the rotating circumferential wall and the guide member. The head hangs down from the conveyance gap and becomes an upright state where it is held and suspended by the upper end edge of the rotating peripheral wall and the guide member, and as the rotating peripheral wall rotates, it is moved along the guide member and sequentially aligned and moves, It is sent out from the discharge section at the end of the guide member. In this way, parts can be fed simply by rotating the rotating disk and the rotating peripheral wall, so the noise is low and the feeding capacity can be increased compared to vibrating parts feeders.Furthermore, since it is motor-driven, the feeding capacity can be reduced due to voltage fluctuations. There is also little variation.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes an umbrella-shaped rotating disk, which is fixed to the upper end of a rotating shaft 2 that is rotatable about the vertical axis 0. Reference numeral 3 denotes a rotating container, which accommodates the rotating disk 1 in its recess 4, has a peripheral wall 4a surrounding the rotating disk 1, and rotates around an inclined axis P that is inclined by about 10 degrees with respect to the vertical axis 0. freely supported.

A support tube 6 extends downward from the center of the bottom wall 3a of the rotary container 3.

A through hole 9 is bored at the axial center position of the bottom wall 8 of the bottomed cylindrical support frame 7 which is inclined concentrically with the inclined axis P and arranged on the frame 5. The portion 6 passes through the through hole 9 and is rotatably supported by the bottom wall 8 via a bearing 10. A pulley 1 is rotatably driven by a pulley 11 attached to the lower end of the support cylinder 6 and a drive motor 13 attached to the bottom wall 8 via a bracket 12.
■Belt 15 is wound around between 4 and 4. The rotating shaft 2 passes through the support tube 6, and its lower end is connected to the bottom wall 8.
It is rotatably supported by a bearing 17 fixed to a bracket 16 extending from the shaft, and is directly connected to a drive motor 18.

The peripheral wall 4n of the surface recess 4 is the outer periphery of the rotating disk 1.

The partially spherical L-shaped disk 1 is fitted with a slight gap so that the rotating disk 1 and the rotating container 3 can rotate relative to each other in a relatively inclined state. A friction plate 19 made of a high-friction material such as urethane rubber is attached to the upper surface of the outer periphery to prevent parts A, which are conveyed objects, from slipping against the rotating disk 1 at the outer periphery of the rotating disk 1, where the circumferential speed increases. It is designed to be adopted as necessary.

The upper end edge 20 of the peripheral wall 4a of the rotary container 3 is formed in a narrow seven-run shape, and one of the outer peripheral edges of the rotary disk 1
＠ is substantially in contact with this upper end edge portion 20, and other portions are located within the recessed portion 4.

An arc-shaped guide member 22 is disposed on the outside of this upper end edge 20 with an appropriate part conveyance gap 21 through which the shaft portion of the part can pass, and is fixed to the support frame 7 with a fixture 23. has been done. Further, a guide wall 24 is disposed perpendicularly to the guide member 22 at an appropriate distance from the inner peripheral edge of the guide member 22 to form a retaining step 26 for the head of the part A.
This guide wall 24 is also fixed to the support frame 7 via mounting fittings 25a and 25b. These guide members 22 and guide walls 24 are connected to the outer periphery of the rotating disk 1 and the rotating container peripheral wall 4a.
It extends from the position in front of the position B where the upper end edge 20 is almost in contact with the upper end edge 20 to the position that has gone around half a turn to 3/4 turn, and the end thereof is part A.
This is the discharge section 27. In addition, these guide members 22
is divided into two parts in the circumferential direction, and the guide member 24 is not divided, but is fixed so that its position can be changed in the radial direction by the fitting 23 and the fittings 25a and 25b. 21 and the width of the engagement step 26 can be adjusted.

A fall prevention wall 28 is provided in a section of the outer periphery of the rotary container 3 where the guide member 22 is not disposed, and prevents the parts A from falling from this portion to the outside of the rotary container 3. The end of the fall prevention wall 28 on the side of the discharge part 27 is connected to the discharge part 2
Recess 4 so as not to interfere with the head of part A passing through 7.
It is located inside the outer peripheral edge 20 of.

The discharge part 27 is provided with a discharge air jet 'l' 29 for penetrating the support frame 7 and the guide wall 24 to promote smooth discharge of the part A, and is not arranged in front of it. An air ejecting pipe 30 is provided for blowing away the P/A that is piled up and moving into the recess 4 of the rotating container 3.

A transfer means 31 is connected to the discharge section 27, and includes a pair of guide rails 32 that engage the head of the part A to slide and transfer the part A in an upright state. A vibrating device 33 is installed to smoothly transfer part A.

In the above configuration, the drive motors 13 and 18 are rotated at appropriate rotational speeds to rotate the rotary disk 1- and the rotary container 3 at a ratio of 2:1, for example, to a countersunk head rivet of 4 x 2 (') m+n. Rotation drive is performed to achieve the rotation ratio.

When part A is put into the four parts 4 of the rotating container 3, the part A is placed on the rotating disk 1, moves to the outer periphery of the rotating disk 1 by the centrifugal force caused by the rotation, and rotates with the outer periphery of the rotating disk 1. At a position B where the upper end edge 20 of the peripheral wall 4a of the container 3 substantially contacts, it sequentially moves onto the upper end edge 20 of the rotating container 3, and further attempts to move radially outward due to the centrifugal force caused by the rotation. Here, the head of part A is positioned astride the upper edge 20 and the engagement step 26 of the guide member 22, and is prevented from moving further outward by the guide wall 24. , par "7 A's shaft part fits smoothly and quickly into the parts conveyance gap 21 between the upper edge part 20 and the guide member 22. As a result, the head part of part A is connected to the upper edge part 20 and the engaging step part. At 26, it is engaged and suspended and assumes a substantially vertical standing position with its details hanging downward.In this state, Par'7 A's head is held between the upper edge 20 of the surrounding wall on the rotating side and the guide member 22 on the stationary side. Since part A is suspended, part A receives relative movement on both sides of the head and moves along guide member 22 into part slow gap 21.
Inside, they are transferred to the discharge section 27 and transported one by one. In addition, at this time, since the par 7A is rotated about its axis by the relative rotation of the rotating container 3 and the guide member 22, the details may fit into the parts conveyance gap 21 between them and take an upright position. The parts A are sequentially and reliably placed in an upright position and transported in alignment. In this way, the parts A are sequentially arranged and moved toward the discharge section 27,
The material is transferred from the discharge section 27 to the guide rail 32 of the delivery means 31 and is supplied to the next process.

The present invention is not limited to the above embodiments, and can be implemented with various modifications. For example, in the above embodiment, the axis of rotation of the rotating disk 1 is vertical and the axis of rotation of the rotating container 3 is inclined, but the axis of rotation of the rotating disk 1 may be inclined. In addition, the guide member 22
Although the guide wall 24 is provided separately, the guide wall may be integrated with the guide member 22, and in some cases, the guide wall may be omitted.6Also, an umbrella-shaped rotating disk 1 is shown as an example. However, a flat plate may also be used. Furthermore, it supports and drives the rotating disk 1 and rotating container 3! I! The design of the IJ configuration can also be changed as desired, and the rotating container 3 can be made into a mere peripheral wall depending on its support and drive method.

(Effects of the Invention) According to the present invention, as described above, with a simple configuration consisting of a rotating disk, a rotating circumferential wall, and a fixed guide member, parts can be aligned and withdrawn in an upright position at high speed. Because it operates by simply rotating the rotating peripheral wall, there is almost no noise caused by vibration, and since the supply capacity is determined by the number of rotations, there is little variation in supply capacity due to voltage fluctuations, etc., compared to conventional vibrating parts. It exhibits a much superior effect compared to feeders.
