Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an article separation and supply device, and is used in article production processes.

(b) Prior art There are various means for separating and supplying articles one by one.
Examples include those described in No.
However, with this device, it is necessary to manually feed the articles into the hopper. If possible, we would like to transfer the material from the stock case, a so-called returnable box, to the separate supply section without human intervention. An example of solving this problem is described in Japanese Utility Model Application Publication No. 58-37134, but this requires the use of a specially constructed stock case whose side walls can be separated.

(C) Object of the Invention The object of the present invention is to provide a device that can transfer rod-shaped articles tightly packed into a stock case of a normal structure to a separation supply section without human intervention.

(d) Structure of the Invention In the present invention, a rotating body that rotates about a horizontal axis is provided, and the opening of the stock case is connected to the rotating end of the rotating body. The rotating body is rotated with the stock case connected, and when the case opening is directed downward, the rod-shaped article is received in the rotating body, and the attitude of the rotating body is changed so that the rod-shaped article becomes horizontal. Here, a chute equipped with an article escape mechanism at the lower end is connected to the rotary body, and by opening the shutter of the rotary body, the rod-shaped article is transferred to the chute side, and is thereafter separated and supplied by the escape mechanism.

(e) Example The outline of the apparatus will be explained based on FIGS. 1 and 2. Reference numeral 1 denotes a rotating body, which is supported by bearing plates 2, 2 rising from a base portion (not shown), and is capable of rotating around a horizontal axis. Support shafts 3, 3 protruding from both sides of the rotating body 1 and supported by bearing plates 2, 2
Small gears 4, 4 are fixed to. Small gears 4, 4 are large gears 6, 6 of a driving shaft 5 supported on bearing plates 2, 2.
Engage with each other. The driving shaft 5 is driven by an air cylinder 7.
Can be rotated 90° back and forth. Small gear 4 and large gear 6
Since the ratio of the number of teeth is 1:2, the rotating body 1 rotates 180 degrees. Reference numerals 8 and 9 indicate a carry-in guideway and a carry-out guideway which are parallel to each other. The carry-in guideway 8 carries in a stock case 11 full of rod-shaped articles 10, and the carry-out guideway 9 carries out an empty stock case 11. The stock case 11 is a flat box with an opening 12 at the top.
A large number of rod-shaped articles 10 are packed therein with their respective axes aligned vertically. This stock case 11 is carried down the carry-in guideway 8 in a state where it is laid down on its side, and after being emptied, it is delivered to the carry-out guideway 9 in a state where it is also laid down on its side.

Next, a more detailed structure of the apparatus will be explained with reference to FIG. 5 and the following figures. A receiving port 13 that is open toward the outside is provided at one rotating end of the rotating body 1, and a receiving chamber 14 is connected to the inside of the receiving port 13. Reception port 13
The cross-sectional shape of the receiving chamber 14 is similar to that of the stock case 11.
It is almost the same as that of the opening 12 of. A movable plate 15 constitutes the bottom wall of the receiving chamber 14, and is supported by a total of four guide rods 16 to move the plate out of the receiving port 13.
Or it is designed to be able to move back and forth inward.
The movable plate 15 is moved by two air cylinders 17 and 18 connected in series. One air cylinder 17 is directly attached to the movable plate 15, and the other air cylinder 18 is attached to the frame of the rotating body 1, and both rods are connected by a joint 19. A shutter 20 constitutes one of the side walls of the receiving chamber 14, and is supported at both ends by the frame of the rotating body 1 so as to be slidable in the same direction as the moving direction of the movable plate 15. 21 is an air cylinder that opens and closes the shutter 20.

In the rotating body 1, the receiving port 13 is connected to the loading guideway 8.
The stock cases 11 are received and delivered by reciprocating between the position lined up on the carry-out guideway 9 and the position lined up on the carry-out guideway 9. Therefore, holding means for holding the stock case 11 is provided at the receiving opening 13. The holding means is formed by connecting a pair of holding plates 22 and 23 that protrude oppositely from the sides of the receiving port 13, and the holding plates 22 and 23 connected to the side far from the loading and unloading guideways 8 and 9. It is constituted by a plate-shaped stopper 24 provided. Holding plate 2
2 and 23 have hook-shaped bent portions 25 and 26, the distance between these and the receiving port 13 is approximately equal to the height of the stock case 11, and the mutual distance between the holding plates 22 and 23 is approximately equal to the width of the stock case 11. equal.

In FIG. 9 and FIG. 10, 27 is a chute for lowering the rod-shaped article in a sideways state, and the receiving chamber 14 has been rotated so that the shutter 20 is at the bottom.
It is placed in a position where it connects to from below. Shoot 2
An elevator 2 that supports a rod-shaped article 10 is provided inside the elevator 7.
8 is provided. Further, at the lower end of the chute 27, a discharge port 29 and a pusher 30 for projecting the lowest layer of the rod-shaped articles from the discharge port 29 are arranged. The discharge port 29 and the pusher 30 are connected to the rod-shaped article 1.
It has a width equivalent to a column. 31 is a conveyor that carries away the discharged rod-shaped article 10. 32
is a slide plate that pushes out the empty stock case 11 onto the carry-out guideway 9 and closes the receiving opening 13.

Next, the effect will be explained. Initially, the rotating body 1 is in a state where the holding plate 23 is aligned with the loading guideway 8, and the air cylinder 18 extends the rod and the air cylinder 17 retracts the rod, so the movable plate 15 is moved from the receiving port 13. It is in a slightly retracted position. Here, the stock case 11 fully loaded with rod-shaped articles 10 is pushed out from the carry-in guideway 8 by a rod (not shown) and transferred to the holding plate 23 in a state where it is lying on its side. This is the state shown in FIGS. 1 and 5, in which the stock case 11 is held with the opening 12 connected to the receiving port 13. Next, the air cylinder 17 extends the rod,
The movable plate 15 comes out of the receiving opening 13 and enters the stock case 11 to support the end surface of the rod-shaped article 10. This is the state shown in FIG. Next, the rotating body 1 changes its attitude so that the receiving port 13 faces upward and stops. First, the air cylinder 18 retracts the rod to move the movable plate 15 backward, and the rod-shaped article 1 is removed from the downward facing opening 12 of the stock case 11.
More than half of 0 is drawn into the receiving chamber 14. Next, the air cylinder 17 retracts the rod and the movable plate 15
is further retreated, and the rod-shaped article 10 is completely taken into the receiving chamber 14. This is the state shown in FIGS. 7 and 8. The reason why the air cylinders 17 and 18 are not operated at the same time is that if they were operated at the same time, the combined speed would be too high, and the rod-shaped article 10 that was in contact with the inner surface of the stock case 11 could not follow the movement and would be left behind, causing other rod-shaped articles to This is because there is a danger of it jumping over 10. Next, the rotating body 1 rotates the rod-shaped article 10
The receiving chamber 14 gradually tilts so as not to disturb the accumulation of water, and reaches a position where the receiving chamber 14 faces the chute 27 across the shutter 20, as shown in FIG. At this stage, the rod-shaped article 10 is in a position with its axis horizontal. At this point, the slide plate 32 advances, and as shown in FIG.
2 to the unloading guideway 9, and at the same time, the receiving port 13 is closed. In this state, shutter 20
When pulled, the pile of rod-like articles 10 falls onto the elevator 28, which is waiting just below the shutter 20. The elevator 28 that has received the rod-shaped articles 10 descends to a position where the lowermost rod-shaped articles 10 are lined up with the discharge port 29 . Here, the pusher 30 advances and pushes one row of rod-shaped articles 10 onto the conveyor 31. This is the state shown in FIG. Thereafter, the extrusion of the articles continues one row at a time, and the stacking of the rod-shaped articles 10 in the receiving chamber 14 gradually decreases in height using the slide plate 32 as a guide. When the rod-shaped article 10 disappears from the receiving chamber 14, the shutter 20 closes, the slide plate 32 also retreats, and the rotary body 1 returns to the position shown in FIG. 5. Since the rod-shaped articles 10 remain in the chute 27, the operation of feeding out the rod-shaped articles continues without interruption until the rotating body 1 returns with a new group of rod-shaped articles.

(F) Effects of the Invention According to the apparatus of the present invention, rod-shaped articles placed in a normal stock case or returnable box can be transferred to a chute and separated and supplied without disturbing the orderly state in which they are placed. The present invention is particularly useful in cases where articles have different heads and tails and need to be separated and supplied without disturbing their orientation.
