Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a transfer device for cylindrical articles and other rotatable articles.

(Background of the Invention and Means for Solving the Invention) Various types of transfer devices for rotatable articles of this type have been proposed in the past.

The present invention has been made to provide an article transfer device that transfers articles based on a novel mechanism that has not existed before, and the gist thereof is (A) for supporting and rollingly guiding rotatable articles. (B) a plurality of guide rails disposed vertically in multiple stages in an inclined state, each stage having an inclination direction opposite to the other; and a delivery means for delivering from the upper guide rail to the lower kite rail, and the delivery means includes (a)
a recess for holding the article, and is rotatable between a position for receiving the article from the upper guide rail and a position for delivering the article onto the lower guide rail; a delivery arm that rotates from the delivery arm to the delivery position based on the weight of the held article; (c) a stopper piece that holds the article at the front end position of the guide rail in a stopped state; and (d) the delivery arm. and engaging means that engages with the arm when the arm rotates in the article receiving direction to rotate the stopper piece to the non-operating position.

(Operation and Effects of the Invention) In the device of the present invention, a cylindrical or other rotatably shaped article to be transferred is supported on a guide rail, and is moved and advanced based on the inclination of the guide rail. When the article reaches the end of the downwardly inclined guide rail, the stopper piece in the delivery means,
Depending on the state of the transfer arm, in other words, depending on whether the article is jammed on the lower guide rail, the article is stopped as is, or the article is transferred onto the lower guide rail. That is, when the lower guide rail is full of articles, the transfer arm of the transfer means is at the article transfer position with respect to the lower guide rail, and the pawl acts to stop the articles at the front end of the upper guide rail. The article is located at a respective position so that an article along the guide rail to the front end is held stationary at the front end of the rail.

On the other hand, when the article on the lower guide rail advances, the article held in the holding recess of the transfer arm moves forward on the lower rail and is removed from the recess, which acts on the transfer arm. Since the weight of the article that was being held is removed, the delivery arm is rotated based on the weight of the balance weight to the upper guide rail side, specifically to the position for receiving the article from the upper guide rail. At this time, the stopper pieces are rotated together by the action of the engaging means, and the stopper piece that has been keeping the article in a stopped state at the front end of the upper guide rail is retracted to a non-operating position.

As a result, the article at the front end of the upper guide rail enters the holding recess of the transfer arm, and when its weight is added to the transfer arm, the arm resists the biasing force of the balance weight and moves onto the lower guide rail. It is rotated to the article delivery position. That is, the article is transferred from the upper guide rail to the lower guide rail.

The above operations are performed one after another for each stage of the guide rail, and the articles are transferred downward.

As described above, in the apparatus of the present invention, the article automatically moves forward based on gravity, and therefore no special driving device or driving force is required for moving the article forward.

Further, in the device of the present invention, a delivery means is provided between the guide rails on the lower L side to deliver the article, and this delivery means does not deliver the article when the lower guide rail is full. This prevents the inconvenience of articles moving on the guide rails being moved onto the lower guide rails with great force and causing disturbances in the arrangement of the articles due to the impact at that time.

The device of the present invention has the feature that the delivery means automatically operates at appropriate timing based on the weight of the article. Therefore, compared to the case where the delivery means is driven by a separate drive device, there is no need for a special drive device or driving force, and there is no risk of trouble occurring due to deviations in the operation timing of the delivery means, allowing goods to be delivered smoothly. It has the advantage of being able to be transported in an orderly manner.

(Example) Next, embodiments of the present invention will be described in detail based on the drawings.

In FIG. 2, reference numeral 10 denotes a cylindrical molding die as an example of an article to be transferred, and a ring-shaped block 16 having a 7-shaped groove is fixed at two locations spaced apart from each other by a predetermined distance. .

A transfer device for transferring the molding die 10 is shown in FIG. The transfer device i15 has a plurality of guide rails 46 arranged in multiple stages (eight stages in this case) within the heating tank 32.

These guide rails 46 are each inclined, and the direction of inclination is opposite for each stage. A delivery device 4 is provided on each end side of the guide rails 46.
8 are arranged so that the molding die 10 is transferred from the guide rail 46 at the upper end to the guide rail 46 at the lower stage. In addition, a discharge device 5 is provided at the discharge port 36 of the heating tank 32.
0 is provided so that the molding molds 10 are discharged to the outside one by one. Incidentally, near the input port 34 of the heating tank 32, there is a sensor 52 for detecting that the molding die 10 is inserted through the input port 34.

Further, sensors 53 are arranged near the discharge ports 36 to detect whether the molding die 10 is at the discharge position.

The transfer device 48 is connected to the shaft 5 as shown in detail in FIG.
It has a delivery arm 56 which is rotatable around 4. A holding recess 58 having a substantially semicircular shape corresponding to the shape of the molding die 10 is formed in the delivery arm 56, and the molding die IO can be held in the holding recess 58.

A balance weight 60 is connected to the delivery arm 56 so as to rotate integrally through a connecting rod 2, and the delivery arm 56 is biased clockwise in FIG. 1 based on the weight of this balance weight 60. ing. That is, the delivery arm 5
When 6 releases molded Venus 10, balance weight 6
Based on the weight of 0, the delivery arm 56 is rotated clockwise in the figure.

A stopper piece 64 is disposed above the delivery arm 56 so as to be rotatable around a shaft 65. This stopper piece 64
is the mold 1 rolling along the guide rail 46.
0 is stopped at the end position, and an engagement roller 66 is provided protruding from the side surface thereof. When the delivery arm 56 rotates clockwise, the engagement roller 66 hits the delivery arm 56 and receives the rotational force, thereby causing the stopper piece 64 to rotate in the same clockwise direction.

As clearly shown in FIG. 4, the ejection device 50 includes a movable rail 68, a stopper arm 70 for holding the distalmost molding die 10 at a predetermined stop position, and the distalmost molding die 1.
It has a delivery arm 72 for sending out 0's one by one. These movable rails 68. Stopper arm 70. The delivery arm 72 is connected to the actuating rod 82.83 via a connecting arm 74.76.80 which rotates together with them. The actuating rod 82 is reciprocated by a cylinder (not shown), which allows the movable rail 68. Stopper arm 70. Both delivery arms 72 can be rotated clockwise or counterclockwise in the figure.

Note that this discharge device 50 is provided with a balance weight 84, and based on the weight, the movable rail 68 and the stop/paper arm 70. The delivery arm 72 is biased clockwise in the figure. This is to make it easier for the movable rail 68 and each arm 70, 72, which have been rotated clockwise by the cylinder, to return to their original positions.

Next, the effects of books 'f and H will be explained.

The molding die 10 placed closely on the guide rail 46) 1 in the heating tank 32 is heated while staying in the heating tank 32.

Here, the molding die 1 at the end on the lowest guide rail 46
0 is held in a stopped state by the stopper arm 70 of the ejection device 150, and the forming molds 10 at the ends (front ends) of the guide rails 46 of each stage other than the lowest stage are held by the stopper arm 70 of each delivery device 48. 64 and is stopped at the front end position of the rail 46.

On the other hand, the molding die 10 at the starting end (rear end) of each stage of the guide rail 46 is held in the holding recess 58 of the delivery arm 56 of the delivery device 48 .

Now, in this state, the molding die lO at the end on the lowermost guide rail 46 is first discharged from the discharge port 36 by the discharge device 50. Its operation is as follows. First, the actuating rods 82, 83 are pushed rightward in the figure by a cylinder (not shown). Then, the movable rail 68. The stopper arm 70 and the delivery arm 72 are each rotated counterclockwise in FIG. 4. By rotating the movable rail 68 counterclockwise, the movable rail 68 is connected to the main body rail, and the arm 70 and the delivery arm 72 are connected to each other.
is rotated, the molding die 10 at the end becomes 1
m, and is discharged from the discharge port 36.

Subsequently, when the actuating rods 82 and 83 are pushed to the left in the figure by the cylinder, the movable rail 68, the bar arm 70, and the delivery arm 72 are each rotated clockwise, thereby forming the distal end. By discharging the mold 10, the mold 10 rolling on the rail 46 is stopped when it has advanced by exactly one mold.

Now, when the molding die 10 on the lowest guide rail 46 is rolled forward by one piece, the rear end on the other guide rail 46 is held in the holding recess 58 of the delivery arm 56 in the delivery device M48. The molding die 10 that had been in place is now pulled out from the opening of the recess 58. Then, the weight of one molding die that had been applied to the transfer arm 56 is eliminated, so the transfer arm 56 is rotated clockwise in FIG. 1 by the weight of the balance weight 60. When the transfer arm 56 has rotated a certain amount, the transfer arm 56 comes into contact with the engagement roller 66 of the stopper piece 64, and the stopper piece 64
Rotate 4 together. Then, the mold lO, which was held in a stopped state by the stopper piece 64, is moved as shown in FIG.
The retention recess 58 of the transfer arm 56 as shown in FIG.
and is held within the same recess. At this point, the transfer arm 56 that newly holds the molding die 10 rotates counterclockwise again due to its weight, and holds it in a state where it is placed on the rear end position of the lower guide rail 46.

Now, when the molding die lO at the front end of the guide rail one step higher than the lowest guide rail 46 is moved to the lower step side, the forming molds lO at that step successively roll on the guide rail 46, forming Move forward by one mold. At the stage when the molding die 10 at the rear end of that stage moves forward, the molding die 10 one stage higher is again transferred onto the guide rail 46 of that stage by the delivery device 48. Such an operation is performed for each stage of the guide rail 46, and the heating tank 3
The molds in 2 are collectively advanced by one mold.

At the same time, a new molding die 10 is put into the heating tank 32 through the input port 34, and the molding mold 10 is again discharged from the discharge port 36, and the same operation is repeated one after another. The mold lO is continuously transferred within the heating tank 32.

As described above, in the case of the apparatus of this example, the mold 10 is automatically and continuously transferred based on its weight.

In addition, in the device of this example, the delivery unit W4g detects that the molding die 10 has moved forward on the lower guide rail 46 and is ready to receive a new molding die 10, and It has a function to detect that a new molding die 10 has come to the position, and when such conditions are met, it automatically operates based on the weight of the molding die lO to change the shape of the molding die 10. Since the delivery is carried out, the molding die 10 can always be delivered at an appropriate timing, which has the advantage that the molding die 10 can be transferred smoothly and in an orderly manner.

Although the embodiment of the present invention has been described in detail above, this is only one embodiment of the present invention, and in the present invention, for example, the balance weight 84 does not necessarily have to rotate together with the delivery arm 72. , it is also possible to configure this in a form other than the above example. Furthermore, the present invention can be applied to the transfer of articles in shapes other than the above-mentioned cylindrical mold, and the present invention may be modified in various ways based on the knowledge of those skilled in the art without departing from the spirit thereof. It is possible to configure
