EXAMPLES The example shown in FIG. 1 will be described. A pair of sprockets 2 spaced apart from the side surface of the bracket 1 which is vertically set,
2'is rotatably supported and one bracket 2 is connected to the electric motor 14. A chain 3 is hooked between the two sprockets 2 and 2'to form parallel endless vertical tracks 4 and 5 which are vertically separated from each other. A pair of horizontal rods 6 and 6'are arranged on the upper and lower sides of the bracket 1 and both ends thereof are attached to the bracket 1.
Fixed to. Guide bodies 7, 7'are slidably arranged on these horizontal rods 6, 6 '. The upper and lower guide bodies 7, 7'are connected to a pair of vertical rods 8, 8 ', and both guide bodies 7, 7'
Are always in the same movement, i.e. slidable simultaneously in the same direction along the horizontal rods 6, 6 '. The channel member 9 is vertically movable between the pair of guide bodies 7 and 7'and along the pair of rods 8 and 8 '. The channel member 9 has upper and lower connecting plates on the side of the bracket 1 and has an opening on the front side in the drawing. The channel member 9 extends outward from this opening and can be moved up and down along a pair of rods 8 and 8 '. Arrange the guide plate 17.

A pin 12 fixed in place on the chain 3.
Is rotatably inserted into the engaging portion 13 of the channel member 9. Thus, the channel member 9 moves along with the chain 3 along the trajectory formed by the chain 3.

The guide plate 17 receives the urging force of the spring 18 wound around the pair of rods 8 and 8'from below, and always contacts the upper plate of the channel member 9. The finger member 11 is extended obliquely downward from the guide plate 17. The lower end of the finger member 11 rotatably supports the protrusion 10 and a lever 20 facing the protrusion 10 away from the protrusion 10 and receiving the biasing force of the spring 19 at the tip of the finger member 11. An opener 21 is arranged in front of the lever 20 so that the finger member 11 moves forward,
When the upper part of the lever 20 comes into contact with the lever 20, the lever 20 rotates clockwise as viewed in the figure, the projection 10 is directly opposed to the work 22 at the point A, and when the work 22 contacts the projection 10, the opener is opened. 21 is separated from the lever 20, the lever 20 is returned to the position shown in the figure, and the work 22 can be conveyed along the track 15 by the finger member 11.

When the channel member 9 rises around the sprocket 2 on the left side in the figure and tries to change the course from the lower track of the chain 3 to the upper track 4 of the chain 3, the stopper pin 23 causes the guide plate 17 to move. Located above the
The guide plate 17 is prevented from rising together with the channel member 9, and the guide plate 17 and the finger member 11 are attached to the work 2
Hold in position 2 to hold. When the channel member 9 rises and enters the upper raceway 4 of the chain 3 and moves to the right in the figure, the stopper pin 23 releases the restraint of the guide plate 17 and the guide plate 17 rises due to the urging force of the spring 18. .

The work 22 enters the point A of the runway 15 through a route 24 indicated by an imaginary line. In order to move the work 22 to the point B, the electric motor 14 is turned on and the chain 3 is rotated in the arrow direction. As the chain 3 rotates, the finger member 11 approaches the opener 21, and eventually the opener 21 contacts the upper end of the lever 20 to rotate the lever 20 clockwise. Therefore, the protrusion 10 comes into contact with the work 22 at the right end on the track 15 and starts moving it forward. At this time, the lever 20 moves forward from the position of the openner 21, and the lever 20 moves toward the openner 2.
The work 22 is released from 1, returned to the position shown in the figure, and the work 22 is conveyed from the point A to the point B. Fixed stopper pin 23 before point B
Are located above the guide plate 17 and restrict the upward movement of the guide plate 17 along the pair of rods 8 and 8 '. Eventually, the channel member 9 begins to rise around the sprocket 2, but the fixed stopper pin 23 causes the guide plate 17 to stay in the position shown in the figure, and further advances the work 22.
When the channel member 9 reaches the outermost end, it means that the guide plate 17 has moved forward of the stopper pin 23, the guide plate 17 is released from the stopper pin 23, and the spring 1
Increased by the biasing force of 8. The work 22 surely moves to the point B. In order to reduce the frictional resistance between the rod 8 and the channel member 9, a low friction elastic sleeve may be arranged in the hole of the channel member 9.

FIG. 2 shows a modification of FIG. The same components as those in the example shown in FIG. 1 are designated by the same reference numerals in FIG. 2 and their description is omitted. The channel member 9'moving up and down along the pair of rods 8 and 8'includes a pair of opposed side plates, and the pair of horizontal bars 25, 25 is fixed between the side plates.
5, the guide plate 1 which receives the biasing force of the spring 18 '
7'supports slidably. When the channel member 9'approaches the direction of the sprocket 2 and the work 22 moves to the point B, the stopper pin 23 'comes into contact with the guide plate 17' and prevents the guide plate 17 'from advancing. Guide plate 1
With the stopper pin 23 'blocking the forward movement of 7', the channel member 9'starts forward and upward movement in accordance with the arcuate surface of the sprocket 2. However, the guide plate 17 '
Holds the work 22 at the position of point B by the stopper pin 23 '. When the channel member 9 ′ comes to the outermost end, the finger member 11 moves to an upper position apart from the work 22, and the finger member 11 eventually starts a returning motion and enters the upper track 4 of the chain 3.

In the example of FIG. 1, the point B is the position corresponding to the outermost end of the sprocket 2, and in the example of FIG. 2, the point B is the position corresponding to the lowermost position of the sprocket 2. In the example of FIG. 1, the position of the point B corresponding to the radial dimension of the sprocket 2 is shown in FIG.
It goes forward from the example.

FIG. 3-5 shows another example. Sprockets 2 and 2'are rotatably fixed to both ends of the bracket 1, and a chain 3 is hung between the sprockets 2 and 2'to form an endless track body. The chain 3 constitutes parallel vertical orbits 4 and 5 which are vertically separated from each other.

Horizontal rods 6 and 6'are provided above and below the bracket 1.
Is fixed to these horizontal rods 6 and 6'and guide bodies 7 and
Arrange 7'slideably. The upper and lower guide bodies 7, 7'are connected by a pair of vertical rods 8, 8 ', and both guide bodies 7, 7'
Allow the same to slide along the horizontal rods 6, 6'in the same direction at the same time. Blocks 9 ″ are arranged along both vertical rods 8 and 8 ′ so that the channel member phase can be moved up and down.
Then, a claw 11 'corresponding to a finger member having the protrusion 10 at its tip is fixed.

Pins 12 are fixed at appropriate places on the chain 3 so as to be orthogonal to the traveling direction of the chain 3. This pin 12
Is inserted into the hole of the block 9 through the sleeve 13 of the elastic member. The sleeve 13 of the elastic member is used for the sprocket 2
9 "and rods 8 and 8'caused by the difference in momentum between the horizontal movement and the ascending movement of the block 9" following the rotation of the
It is useful for reducing the sliding resistance between and. When the electric motor 14 as a power source is turned on and one sprocket 2 is rotated in the arrow direction, the pin 12 on the upper track 4 is rotated.
Moves the block 9 "to the left. When the pin 12 passes around the sprocket 2 and enters the lower track 5, the block 9" is also lowered along the vertical rods 8 and 8 ', and the transfer direction is also left. Changes from to right. Therefore, the item A is
It is pushed by the projection 10 of the claw 11 ', and along the track 15 B
Move to a point. At point B, the pin 12 moves around the sprocket 2'to the upper track 4 side, so that the block 9 "and the claw 1
1'also rises, and the work of pushing out the article by the protrusion 10 is eliminated. By repeating this, the articles are continuously transferred from the point A to the point B. The movement of the article at this time is accurate from a certain position (point A) to a certain position (point B) through a certain passage.

When the electric motor 14 is reversed, the block 9 moves in the direction opposite to the arrow, allowing the article to be pulled back from point B to point A.

As shown in FIG. 2, it is preferable to provide a protrusion 10 'which is separated from the protrusion 10 of the claw 11'. The transfer of goods is
Usually, this is done by pushing with the protrusion 10, but the article receives inertial force during the transportation of the article in the arrow direction. Therefore, when the claw 11 'starts to move upward from the horizontal movement and the protrusion 10 and the article separate from each other, the article advances due to inertial force, and the article does not stop properly at the point B. One of the protrusions 10 'receives this article, eliminates the inertial force, and enables the article to stop accurately at point B. When the article is pulled by the projecting portion 10 '(movement in the direction opposite to the arrow), the projecting portion 10 stops the movement of the article and makes the inertial force zero.

In the example shown in FIG. 3, the protrusion 10 'is rotatable around the pin 16, and in this example, the article 10' is protruded.
When it is received by, another protrusion 10 'is raised to the imaginary line position. When an article is received by the projection 10, another projection 10 'returns to the solid line position. After that, the same operation as in the example of FIG. 2 is performed. The supply of articles to the track 15 may be along the track 15 or may be orthogonal to the track 15. The example of FIG. 2 is the runway 15
Is preferable, and in the example of FIG. 3, the supply of articles along the track 15 is preferable.

[0022]

According to the present invention, articles can be transferred by pushing or pulling between fixed positions at fixed intervals (dimension between sprockets and speed of chain). Since the movement of the article can be precisely controlled in time and dimensions, it is most suitable for application to the assembly line of precision equipment.
