Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a feeding device for feeding parts having a substantially cylindrical surface, such as bolts, screws, rivets, knock bottles, etc., to tools such as impact wrenches and nut runners.

<Prior Art> Conventionally, for example, in a device for supplying bolts to an impact wrench, the bolt is supplied through a feeding passage into a component placement chamber formed in the main body, and the bolt is positioned by the peripheral wall of the component placement chamber, and then the bolt is It is designed to be attached to a wrench socket.

However, with the above-mentioned conventional device that supplies bolts to the impact wrench, the necessary clearance around the bolt in the component placement chamber causes the bolt to move loosely in the component placement chamber, making it difficult to position the bolt accurately. Unable to do so, as a result,
There is a problem in that the bolt cannot be reliably and smoothly supplied to the impact wrench.

<Object of the Invention> Therefore, the object of the present invention is to provide a tool for parts that can securely hold parts in a parts placement chamber, accurately position parts, and, therefore, reliably and smoothly supply parts to the tool. The purpose is to provide a supply device.

<Structure and operation of the invention> In order to achieve the object described in (d) above, the structure and operation of the present invention is such that a magnet is arranged on the side wall of the component placement chamber so that the side surface of the component having a substantially cylindrical surface is attracted by the magnet. The present invention is characterized in that the above-mentioned parts are rolled to a balanced position, accurately positioned, and securely held.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In FIG. 1, 1 is a board, 2 and 2 are a pair of rails provided on the board 1, 3 is a slide table that is run by a cylinder 4 on the rails 2 and 2, and 5 is a tool mounted on the slide table 3. In the impact wrench as an example, 6 is a socket attached to the drive shaft 7 of the impact wrench 5, and 8 is a magnet provided at the tip of the socket 6.

On the other hand, 11 is a tool supply device provided at the tip of the substrate 1. The main body 12 of the tool supply device 11 includes first and second
As shown in the figure, the parts placement chamber 1 is partially provided outside the notch.
3 is formed. One side wall of the component arrangement chamber 13 is formed by a movable side wall 15, and a flat magnet 16 is provided on the movable side wall 15. At the inner light end of the movable side wall 15,
A stopper part 17 is made to protrude so that parts such as bolts can be stopped.

On the other hand, a feeding passage 18 is opened in the fixed side wall of the component placement chamber 13 facing the movable side wall 15.
The center line A of 8 intersects the center line B of the component placement chamber 13 at an oblique angle of 45 degrees or less. A 'J & connecting pipe 19 is connected to the feeding passage 18, and a bolt 21 sent from a hose (not shown) is connected to the vibrator 19. Feeding passage]
8 into the component placement chamber 13.

A component ejection hole 23 is opened at one end of the component placement chamber 13, and a tool hole 24 into which the socket 6 is slidably fitted is opened at the other end. and can pass through the component ejection hole 23.

On the other hand, the movable side wall 15 of the component placement chamber J3 is movable in one direction perpendicular to the center line B of the component placement chamber 13 by the first cylinder 25. In addition, the first
The cylinder 25 can be moved in the direction along the center line B by a second cylinder 26. That is, the movable side wall 15 is arranged in a direction perpendicular to the center line B,
It can be moved in both directions parallel to the center line B.

In FIGS. 1 and 2, reference numerals 31 and 32 are component sensors consisting of, for example, a light emitter and a light receiver, which detect the component 21 in the component placement chamber 13.

In the component tool supply device configured as described above, the bolt 21 sent from a hose (not shown) is guided into the component placement chamber 13 by the connecting pipe 19 and the feeding passage 18, as shown in FIG. It will be done. The bolt 21 is held against a stopper portion 17 in the component placement chamber 13, and the side surfaces of the bolts 2 and 1 are attracted to the magnet 16. Then, as shown in Figures 3 and 4, the bolt 21 rolls left and right as shown by the arrows X and Y in Figure 3 until the attraction force of the magnet 16 is balanced, and the bolt 21 rolls left and right as shown in Figure 4. It stops at the center line C of the magnet 16 shown. That is, bolt 2
1 is reliably held on the movable side wall 15 and accurately positioned. At this time, the centerline of the bolt 21 is located on the centerline B of the component placement chamber 13 and the centerline of the outlet 23 and the tool hole 24.

In this state, the impact wrench 5 moves the movable side wall 15 to the first position toward the socket 6 which is being rotated at low speed.
It is moved by the second cylinder 26 as shown by arrow P in the figure. Then, the bolt 21 is accurately positioned at the center of the component placement chamber 13 and the tool hole 24 by the positioning action of the magnet 16, and
) Since the head of the bolt 21 is held in the center without any movement, the head of the bolt 21 is fitted into the socket 6 reliably and smoothly.
Then, it is held by the magnet 8 of the socket 6.

Next, the movable side wall 15 is moved back in the direction of the arrow Q in FIG. Tighten the bolt 21 to the object to be tightened.

Note that the impact wrench 5, the first one. 2nd cylinder 2
The sequence control in 5.26 is controlled by the outputs from the component sensors 3 and 32.

In the above embodiment, the component extraction hole 23 and the tool hole 24 are provided at substantially opposite positions, but the tool hole is omitted, and the tool is allowed to enter the component placement chamber through the component extraction hole, and the component is mounted on the tool. You can do it like this.

<Effects of the Invention> As is clear from the explanation in J- below, the component tool supply device of the present invention is configured as described above, so that it can securely hold components in the component placement chamber, and Accurate positioning and therefore reliable and smooth feeding of the part into the tool
