Abstract

PURPOSE:To operate a high speed discharge as a whole in an unscrambler, by decelerating a vessel conveying machine only at charging and operating conveyance at a high speed when a vessel is intermittently charged into a continuously rotating screw and conveyed. CONSTITUTION:An inverted state vessel A dropped into a chute 14 from a vessel conveying machine 2 is inverted by an aligning device 20 in a bottom part of the chute 14 all into a normal state. Then the vessel is fed by a discharge chute 24 to a vertically conditioned vessel discharge device B. Here the vessel is dropped into between a screw 27 and supporting wall 26 by stoppers 28, 29 moved shuttling synchoronously with the screw 27 by rotary solenoids 30, 31. Only at this moment of dropping, a vessel conveying mechanism C is decelerated by a decelerating machin, not shown in the drawing, interlocked to an opening switch of the stopper 20. By this constitution, speed during conveyance can be arranged to a high speed to enable the high speed operation of a device as a whole.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container discharging device, and a container discharging device that intermittently feeds a group of containers to a continuously rotating screw in, for example, an a/scrambler, and transports and discharges the containers. It is related to.

Conventionally, in an unscrambler or the like, a plurality of containers are intermittently dropped into each pocket of a continuously rotating discharge screw installed on a conveyor, and the containers are discharged by the rotation of this screw. In such a discharging device, the container falls due to its own weight, so the falling time of the container is constant, but in order to increase the discharging capacity, the rotation of the screw is changed. If the speed is increased, the last of the containers being ejected will be located below the next group of containers to be removed. Because of this interference, the rotation of the screw cannot be increased, which limits the discharge capacity of the device.

The present invention has been made to eliminate the above-mentioned drawbacks, and includes a plurality of container receiving sections for receiving containers individually.
These include: a container transport mechanism that transports and discharges a group of containers received in each container receiving section; a prime mover that drives this transport mechanism; In a container unloading device equipped with a container loading mechanism for intermittently loading a group of containers, a transmission mechanism is provided to control the prime mover and reduce its rotational speed by T′iJ, and a transmission mechanism is provided from the loading mechanism to the container receiving part n. By slowing down the container transport mechanism only at the moment when a group of containers is loaded, the normal operating speed of the container transport mechanism is increased, and the speed is reduced only when containers are loaded, allowing containers to be smoothly loaded, thereby increasing the overall high-speed discharge capacity. The purpose of the present invention is to provide a large container discharging device.

The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, (1) is a hopper that stores a large number of containers (A);
(2) is a container transfer mechanism installed at an angle below this hopper, and this container transfer mechanism has shafts (3) and (4) rotatably supported at the upper and lower ends, and The religious pulleys (5) and (6) attached to the shaft and each pulley (5, l l (
fl) The belt (7) passed between the hooks and the container pushing members (7) installed at predetermined intervals (7) and the valley belt (7)
8). Moreover, as clearly shown in FIG. 6, there are tN,
A guide (9) is provided on both sides of the outer surface of the container (A),
The upper surface of each pair of guides (9) is an inclined surface inclined inward so that a large number of containers stored in the hopper (1) can be guided to the same guide of each set of guides (9).

In addition, as shown in Fig. 1, an impeller (3Q f
The containers that are piled up on the valley collar (A) and are about to be transported by the container transport mechanism (2) are knocked into the hopper (1) by the rotation of the impeller (10). I try to give it a bath. On the other hand, on the downstream side of this impeller i, 10), as can be understood from Figures 1 and 6, there are two rotating shafts +! 0) , (A substantially elliptical shape is arranged on each rotating shaft so that it alternately appears and disappears into the hopper (1) from between the guide (9) of the above-mentioned group and the guide (9) of the other group. Therefore, the container (A) stored in the hopper (1) falls between each set of guides by the inclined surface of the guide (9), and the container The pushing member (8) & twists the container (A) to transport it upward along the guide (9).In this case, the container (A) crosses the guide (9) and rides on the guide, or the container (A) is moved in an arch shape between the guides. Even if a situation occurs in which containers are piled up inside the guide and do not fall, the containers will be moved by the cam plate (18) that appears in the hopper (1) or the arch-shaped container. Because the stack is broken, the containers (in season) will surely fall between the guides.Then, the containers that are stacked on top of the containers (A) that have fallen between the guides and are transferred together with the containers are transported by the impeller (10). t' is knocked down into the hopper (1) by the hopper (1).
The containers are sequentially transferred and picked up one by one by the container transfer mechanism (2).

However, as shown in FIG. 1, the container transfer mechanism (2)
A shoe) (la) is connected to the upper end of the container transfer iRM (2) to guide the picked up CC container A) to fall diagonally downward, slightly inclined from the vertical direction. At the bottom of 04, as shown in Figure 2, there is a stopper (1) that appears in the chute (1) to stop and release containers falling inside the chute.
5) and a container holding member (i6) that holds the container following the released container in a stopped state when the stopper μs) is released. The above stopper (I5
) and container holding member α6) are rotary solenoid Q
7), the shaft (18) is momentarily rotated back and forth by a predetermined angle.
It is fixed at n. Therefore, as shown in Figure 2,
The stopper 05) protrudes into the chute (14i) and the container (
When the rotary solenoid (A) is energized and the shaft (18) instantaneously rotates by a predetermined angle, the stopper μ5) (((A) comes in contact and is prevented from falling). When the stopper is released, the container falls downward, and at the same time, the containers following the dropped container are suppressed by the container holding member α6) against the inner surface of the chute, and are prevented from falling.Then, the rotary solenoid σ When the stopper and the container holding member (16) return to their original states, the containers that had been prevented from falling by the container holding member α6) fall in the chute oa and are held by the stopper (16).
b) The fall is stopped by n. At this time, if there is no container to be held down by the container holding member α6) and the container falls with the container holding member α6) protruding into the chute 04, this container will not be held by the container holding member α6). The fall is stopped when it comes into contact with α6), and then the fall is stopped by the stopper μs).

In addition, a limit switch is provided at the top of the chute C141 that is activated by the passage of the container (A), so that when the container remains in the chute (141) and the limit switch (19) is continuously activated, The above container transfer mechanism (2)
It is possible to stop the

The containers falling through the chute are a mixture of those in the royal state and those in the inverted state, so below the chute, the containers in the inverted state are inverted and all the containers are in the royal state. In order to align the containers, a container alignment device (2) is provided. This container alignment device (2) has a rod-shaped support member (2
1: and an opening (14a
) for pushing out the container in the lateral direction. The distance between the support member (211) and the support surface (14) formed by extending the lower surface of the chute circle is such that the gap between the support member (211 and the support surface (14) is such that it allows the passage of the neck (a) of the container (Al) and the shoulder (b) of the container.
), a concave part (21aJ) is formed in which only the neck part (a) can be accommodated. Therefore, the container (A) falls upside down in the chute 0 (turn). When it comes, K is the shoulder fb of the container)
is stopped by contacting the support member 121)
On the other hand, when the container falls in an erect state, the bottom surface of the container comes into contact with the support member +211 and is stopped. Further, the vertical interval of the opening (14aj) is set to be slightly larger than the length of the body (C) of the container (A).

The container pushing member (roller) is attached to a rotating shaft 123), and the body IC) of the container +A) can be pushed out laterally by reciprocating rotation of the rotating shaft -).

Therefore, when the container (A) is inverted, the support member (2
When the neck part (a) of the container (A) is housed in the recessed part (21a), the container (A) is pushed out laterally between the container pushing members. The container is rotated around a support member 1211 that supports the step between its neck (a) and shoulder (b).
Then, it is inverted and dropped into a discharge chute arranged diagonally downward with the bottom facing the direction of travel, that is, in a royal position. On the other hand, when the support member (211) stops the container (A) in an upright state, the container (A)
) is initially moved laterally by the container pushing member (support). ) is rotated around its support member wI, and when the bottom surface of n1 is detached from the support member (21:), the container faces the direction of travel with its bottom surface facing the direction of travel, that is, the container remains in an upright position without being turned over and passes through the discharge chute. It falls on H.

The above-mentioned discharge chute is curved vertically downward from the middle thereof to face above the container discharge device (B) according to the present invention. This container discharging device TB) is constructed as follows. That is, the discharge shoe t14t is disposed below n, i, the supporting wall rigidity and the screw 1f? /l, and this ejection shoe) opens above the gap between f241
Stoppers 1281 and (291) are provided at the center, and each stopper is connected to the shaft J21 which is reciprocated by the stopper (rotary solenoid similar to the size) and +811.
It is attached to t1831. These stoppers +61
, 1291 is designed such that the solenoid is operated in synchronization with the rotation of the screw a) to sequentially drop the containers and drop them into the screw (tough).Furthermore,
A conveyor is installed at the mid-lower position between the screw cover) and the support wall.
A plurality of rows of containers dropped into the gap between the container and the container can be transferred in a row in the lateral direction.

In addition, each of the above stoppers (15), □□□l s +29
Rotary solenoid (17) that rotates I m
It goes without saying that a conventionally known mechanism such as an air cylinder may be used for the stan.

As a result, the containers (A), which were aligned in a royal state by the container alignment device (2) and dropped into the discharge chute (A), were sequentially moved by their own weight to the stoppers (A) and (A), and then the screw Drop into the gap between the bell and the supporting wall □□□ノ.
and placed on the conveyor cutting surface. Then, the containers placed on the conveyor are moved laterally by the conveyor and the screw, and are discharged to the outside in an upright row.

The feature of the container discharging device (B) having the structure f' as described above is that the container transport mechanism fc' consisting of a screw (rotation) and a conveyor field is used only at the moment when a container is thrown in from the stopper 129). ) is designed to slow down the speed.

A speed change mechanism (
D) will be explained. FIG. 4 is an expanded view showing the interlocking relationship of the drive mechanism of the container discharging device (B).
The rotation of the kari is the drive shaft + 861s axis (371, gear ＼ ceramic, ■
) to the screw (5). On the other hand, the drive shaft (the rotation of the size is a bevel gear t44s%11s,
It is transmitted to one conveyor via the shaft (6)). The screw (support) and the conveyor are rotated or driven in the direction of the arrow in FIG. 4 to transport and discharge the container.

On the other hand, the rotation of the shaft 186) is decelerated by the speed reducer trace)vc and transmitted to the shaft (6)). This shaft (3)) is equipped with a cam plate j#r which operates an inlet inch that releases the stopper rigidity and causes the container to fall. 1 and a cam plate that operates a switch decoy to control and reduce the rotation of the prime mover side. In addition, these cam plates 1117i
.

The axis μs) supporting the - is determined by the speed reducer quotient) according to the number of container receiving parts (27, aJ) of the screw arrangement), for example, if the container receiving part n (27aJ is 15 and
The speed is reduced to n.

The operation of the above-mentioned drive system and the state of the containers to be loaded and conveyed will be explained with reference to FIGS. 4 to 6. Figures 5 (a) to (d) and Figure 6 show the last containers (El), (Fj
2) Container (Fl), (F2-CF3) located at the tip of the group of containers to be introduced following s(E3) and (E4).
*This is a diagram showing the positional relationship with CF4 over time.

First, a group of containers loaded into the previously rotated screw is conveyed, and just before the last container in the group of containers is completely discharged, the cam (cam) activates the switch to close the stopper ( 2) 1 is released and the downgrading of the next container group begins. At this time, as is clear from FIG. 5(a) and FIG. M6, the leading container (Fl) of the next container group is located almost directly above the previous last container (El).

The loaded containers gradually fall due to their own weight as shown in Figs. On the other hand, this one
Immediately before a group of containers contacts the screw thread, this screw (rotation) and conveyor move the container to be thrown into the last container (B) of the previous time or the top part of screw @7j (27t).
+) is decelerated so that it falls smoothly without interfering with the That is, when the cam (cam) activates the switch system, the rotation speed of the prime mover (Zheng) is reduced, and this reduced rotation is transmitted through the drive shaft (86I), one of which is connected to the shaft (town, gear ■l s I
a91 and the screw IZ71, the other is transmitted to the bevel gear 1, the shaft 1, the shaft 1 and the conveyor.
Then, the container transport mechanism (C1) consisting of a screw head and a conveyor is decelerated f'L.In this way, the container transport mechanism (C) is decelerated in synchronization with the falling of the container group, so that each container receiving section (N) Containers can be smoothly placed into the 27aJ.

Since both the above cam plates (6) and (@) continue to rotate γ due to the shaft (6)), immediately after the cam contacts the switches (I, 18J), they are separated from the switches (t461, 1481) (n1, therefore, the stopper (I29)). returns to its original state and waits for the subsequent group of containers to be fed from above, and the prime mover returns to its original high speed rotation to rotate the screw ``)'' and the conveyor 7.
During this period, the speed is accelerated to the speed before deceleration. In this way, by normally operating the container transport mechanism tc) at high speed and decelerating it only for the moment of the two container throwers, it is possible to smoothly receive a group of containers, and the discharging capacity of the container discharging device is significantly improved. can be increased.

As described above, according to the present invention, the speed of the container transport mechanism is reduced to a speed at which containers can be smoothly loaded only when containers are loaded, so that the capacity of the container discharging device can be significantly improved.
