Description

[Detailed Description of the Invention] Technical Field The present invention is an apparatus for transferring cylindrical articles, in particular, transfers cylindrical articles sequentially supplied from a first conveying line to a second conveying line different in conveying direction from the first conveying line. The present invention relates to a device that corrects the posture of a cylindrical article before transferring it to a second transfer line.

Prior Art As this type of article delivery device, there is a device as shown in FIGS. 3 and 4 that is conventionally known. That is, cylindrical articles such as rod pistons 3, which are sent one by one by the chain conveyor 1 that is the first conveyance line, are detected by the limit switch 5 when they leave the chain conveyor 1, and are reciprocated. By raising the cylinder 7, it is placed on an arm 9 attached to the upper end of the reciprocating cylinder 7, and it rolls on this arm 9 and fits into the groove 9a. On the other hand, the limit switch 11 detects the rise of the reciprocating cylinder 7, stops the rise of the cylinder 7, and also controls the rotation cylinder 1.
3, the arm 9 is rotated by a predetermined angle to correct the posture of the rotary piston 3, and then the rotary cylinder 13 is rotated by a predetermined angle.
By detecting the rotation of the cylinder 7 with the limit switch 15 and lowering the cylinder 7, the rotary piston 3 placed in the groove 9a of the arm 9 is moved to the second conveying line 17 which has a different conveying direction (angle) from the chain conveyor 1. hand it over to The lowering of the reciprocating cylinder 7 is detected by the limit switch 19, and the lowering of the cylinder 7 is stopped and the rotating cylinder 13 is stopped.
Return to the initial position. This completes one cycle,
The rotary pistons 3 are transferred one by one from the first conveying line 1 to the second conveying line 17.

However, such conventional delivery devices not only have a complicated structure and control, but also
There are problems such as there is a limit to how much cycle time can be shortened, there are many breakdowns, and energy is required.

Purpose of the invention An apparatus for sequentially delivering cylindrical articles sequentially supplied from a first conveyance line to a second conveyance line whose conveyance direction is different from that of the first conveyance line,
The purpose of the present invention is to simplify the structure of the entire device and reduce failures.

Structure of the invention According to the invention, an arm is provided that is swingable about a horizontal axis at the cylindrical article delivery position as described above, and the arm is attached to the upper surface of one end of the arm in the non-swinging position. The arm has an upper surface for rolling the article supplied from the first conveyance line, and the upper surface of the other end of the arm is provided with an article locking part for preventing the article from rolling and controlling its posture. When the arm is tilted by swinging due to the weight of the article at the stop part, the article is configured to escape from the stop part and be transferred to the second conveyance line, and furthermore, a liquid is placed at one end of the arm. A weight acting inside is suspended, and a resistance plate is placed on the weight, which has a specific gravity larger than the specific gravity of the liquid but smaller than the specific gravity of the weight. When swinging from the swinging position to the swinging position, the resistance plate is raised along with the weight to perform the swinging slowly, and the article is released from the locking part and the arm is moved from the swinging position to the non-swinging position. When returning to the moving position, a transfer position for the cylindrical article is provided in which the weight is lowered before the resistance plate so that the return can be carried out quickly.

Embodiment In FIGS. 1 and 2, the cylindrical article 3 to be delivered is, for example, several kinds of rod pistons having a diameter of 20 mm, a length of 330 to 390 mm, and a weight of 840 to 930 g. Rot piston 3 is washer 2
After being washed in step 1, the pieces are sent one by one by a chain conveyor 1, which is a first conveyance line. A pair of fixed chute 23, 23 is provided at the end of the chain conveyor 1, and the rod piston 3, which has passed through the fixed chute 23, 23, moves to a pair of swing arms 2 formed as a movable chute.
Rolling on 5,25.

The swinging arms 25, 25 are made of, for example, wear-resistant polymeric polyethylene, and the support 27
It is supported so as to be swingable about a horizontal axis P, and in its initial position or non-swinging position, it is maintained at the position shown by the solid line in FIG. 2 by a stopper 29 and a resistance plate (weight) 31. In this non-swinging position, the arm 25 is in a horizontal state or has a slight downward inclination toward the second conveying line 17, and the rotary piston 3 that has passed through the fixed chute 23 is caused by its inertia or by the inclination of the arm 25. It is set to such an extent that it can sufficiently roll on this arm 25. In addition, as shown in FIG. 1, the fixed chute 23, 23 is
A pair of swing arms 25, 25 are provided in the same direction as the transport direction of the fixed chute 17, 17, which is the second transport line, and a pair of swing arms 25, 25 are provided in the same direction as the transport direction of the fixed chute 23, which is the second transport line. Although the directions (angles) of the movable arms 25 are different, the rotary piston 3 is smoothly transitioned between them.

A rotary piston 3 is attached to the other end of the swing arm 25.
A pair of notches 33a and 33b are provided to prevent the rotary piston 3 from rolling and to correct the attitude of the rotary piston 3. First, one side of the rot piston 3 enters the notch 33a and stops. The other side rotates around the notch 33a due to inertia, rolls or slides to the notch 33b, and stops there. At this time, due to the weight balance of the swinging arm 25, that is, due to the weight of the rotary piston 3, the swinging arm 25 is slowly rotated clockwise (Fig. 2), and near the end of the swinging of the swinging arm 25. The rot piston 3 escapes from the pair of notches 33a and 33b and is delivered onto the fixed chute 17, which is the second conveyance line. On the other hand, after the rotary piston 3 passes the end of the swing arm, the swing arm 25 rotates counterclockwise (FIG. 2) due to its weight balance and returns to its original position.

On the opposite side of the swing arm 25 from the notches 33a, 33b, a string or rod 41 is provided with a resistance plate 31 and a weight 39. Due to the action of the resistance plate 31 and the weight 39, the swing arm 25
The oscillating motion is performed smoothly to achieve the desired purpose. On the other hand, if only a simple weight is provided, it is not possible to accommodate several types of rod pistons 3 having different weights, and a satisfactory result cannot be obtained. In other words, if you set the weight to fit an 830g rod piston,
When a 940g rod piston comes flowing, the swinging arm 25 tilts at a fast speed, and the rod piston escapes from the swinging arm 25 before the posture (direction) of the rod piston is determined, and the rod piston is smoothly moved to the second position. It is not inherited to the conveyance line 17.
On the other hand, if the weight is set to fit a 940 g rod piston, the swing arm 25 may not tilt completely when an 830 g rod piston comes flowing.

Therefore, in the present invention, a braking device 35 is provided that includes the above-mentioned resistance plate 31 and weight 39 and buffers the swinging motion of the swinging arm 25. In FIGS. 2 and 2a, a hole 31 is provided in the center of the resistance plate 31.
A is provided in the hole 31a, and a string or rod 41 hanging from the other end of the arm 25 is passed through the hole 31a, and a weight 39 is attached to the tip of the string or rod 41.
is installed. The resistance plate 31 and the weight 39 are placed in water 37 in the container of the braking device 35, and the resistance plate 31 is placed in the water 37 in the container of the brake device 35.
It has a much smaller specific gravity than that of 9. Therefore, when the resistance plate 31 rises, it rises slowly due to the resistance of the water, and therefore the swing arm 2
5 swings slowly and slowly transfers the rod piston 3 to the fixed chute 17. On the contrary, swing arm 2
When 5 returns to its original position, it is quickly returned by the action of the weight 39. At this time, the resistance plate 31 slowly descends along the string or rod 41 until it abuts against the weight 39. As a result, if the rotary piston is heavy (940g), the swing arm 25
The slope of the rod tries to become faster, but the faster the water resistance becomes stronger, the lighter the rot piston (830g) becomes.
If this is the case, the water resistance will be small, and the swinging arm 25 will have an almost constant slow tilting speed despite the change in the weight of the rotary piston.

Effects of the Invention As described above, according to the present invention, since a braking means is provided to buffer the swinging motion of the arm, the arm swings slowly from the non-swinging position to the swinging position due to the weight of the article. During this time, it is possible to control the posture of the item, and the arm swings due to its own weight.
Control of the attitude of the article during arm swinging can be advantageously combined.

The overall structure of the device is simple, so there are fewer failures, and the delivery of cylindrical articles does not require external energy such as electricity, hydraulic pressure, pneumatics, or the accompanying control system. A device is obtained.

Industrial Application Fields The present invention can be applied not only to the delivery of rotary pistons, but also to the delivery of all cylindrical articles. In that case, the shape and size of the resistance plate 31 can be appropriately selected depending on the weight of the cylindrical article.
