Description

[Detailed Description of the Invention] The present invention is an improvement of a container discharging device in which a container that is transported while being stored in a pocket of a carrier is dropped along an inclined guide device at a discharging section and is discharged onto a discharging conveyor. It is related to.

FIG. 1 shows an example of a conventional container discharging device, in which a carrier 1 has a pocket 1a, stores a container 2, transports it in the direction of arrow a, and discharges the container 2 at a discharge section 3. It's getting old. A guide member 4 is provided along the conveyance path of the carrier 1 and guides the bottom of a container stored in the carrier 1 and conveyed, and is fixed to a frame (not shown). 5 is a roller shaft that is pivotally supported at both ends by the adjustment device 6, and while in contact with the bottom of the container 2, the carrier 1
The container 2 is rotated at a linear speed faster than the traveling speed of the pocket 1a, and the container 2 is brought into contact with the front inner wall 1b of the pocket 1a. Further, by rotation of the handle 7 of the adjusting device 6, the guide member 8 and the roller shaft 5 move forward or backward relative to the container guide 9, thereby adjusting the falling distance of the bottles at the top of the container guide 9.

Reference numeral 10 is a container pushing cam fixed to a shaft 11 and adjusted to be synchronized with the carrier 1. The container pushing cam 10 has two working surfaces, one working surface 12 receives the containers 2 and transports them downwards, the other working surface 13 moves the containers 2 along the platform 14 onto the conveyor 15.
It is designed to be pushed over the top.

In the above configuration, the adjustment device 6 is moved forward or backward according to the size (diameter) of the container 2 to adjust the interval at which the containers fall. It is difficult to uniformly adjust the spacing, and when the container 2 falls onto the working surface 12 of the cam 10 in the discharge section 3 due to its own weight,
The roller shaft 5 and the container guide 9 may be misaligned and get caught, and since the container guide 9 is fixed, the catch may not be released and the container may be damaged or damaged, or the machine may be damaged. There was a risk of damaging the machine itself, and it could not adequately handle the high-speed operation of the machine. Furthermore, while the container 2 falls along the container guide 9 and is pushed out onto the conveyor 15, its mouth portion moves below the roller shaft 5, and water droplets attached to the roller shaft are removed from the container. It may drip inside the body, which is not sanitary. It had various problems such as.

Especially in recent years, in beverage bottling plants,
From the perspective of maintaining the quality of the products filled in containers,
There are many requests to reduce the amount of water droplets remaining in bottles before bottling.

The present invention was developed in response to such demands, and the container that is stored in the pocket of the carrier and is conveyed while being supported by the bottom guide is transferred to the inclined guide device via rollers at the discharge section. A container discharging device configured to deliver a container to a container, drop it along the inclined guide device, and discharge the container onto a discharge conveyor, wherein the opening width along the circumferential direction of the outer peripheral surface of the roller is narrower than the bottom diameter of the container, and This is a container discharging device in which a V-shaped groove for guiding the side of the container is formed which is wider than the outer diameter of the container mouth.

An example of the present invention will be described below with reference to FIGS. 2 to 4.

A carrier 21 has a pocket 21a, stores the container 22, transports it in the direction of arrow a, and carries it to the discharge section 2.
3, the container 22 is released. 24 is a bottom guide of the container and outer plates 25a, 25b.
is fixed to. 26 is a roller, which is attached to the shaft 27 in accordance with the number of rows of carriers 21;
As shown in the figure, a V-shaped groove 26 is provided to prevent water droplets A from scattering around the outer circumference of the container 22 and dripping into the inside of the container.
It has a. Note that the shape of the V-shaped groove 26a is such that if the width of the groove at the outer periphery is larger than the outer diameter of the bottom of the container, the stability of the container will deteriorate, and if it is smaller than the outer diameter of the mouth of the container, water droplets will enter the container. Therefore, it is necessary that the outer diameter be smaller than the outer diameter of the bottom of the container and larger than the outer diameter of the mouth of the container, as shown in FIG.

Further, the shaft 27 is pivotally supported by an adjustment device 28, and is adapted to rotate the roller 26 by a chain wheel 29 at a linear speed higher than the conveyance speed of the carrier 21.

A container guide lever 30 is rotatably supported on a shaft 31. Reference numeral 32 denotes a container guide made of plastic or the like, which guides the body of the container 22 with adjacent ones as shown in FIG. It is slightly curved in accordance with this, so that when the bottom of the container 22 is separated from the rollers 26, the front (upstream side in the conveyance direction) body of the container 22 is received.

33 is a balance weight and a container guide lever 30
It is provided at the end of the lever 34 on the opposite side.

A lever 35 is fixed to the shaft 31, and its end engages with an adjustment bolt 37 of a stopper 36 fixed to the outer plate 25a.

38 is a rotating shaft, and on the same shaft 38 is a container pushing cam 3.
9 is fixed and synchronized with the carrier 21. The container pushing cam 39 has two working surfaces, and the working surface 40 receives the bottom of the container 22 and, together with the body guide of the container guide 32, pushes the container 22.
is placed on the platform 41, and the working surface 42 is adapted to push the container 22 along the platform 41 onto the conveyor 43.

44 is a limit switch that detects an abnormality in the ejection operation, and is in contact with the lever 35;
rotates and leaves contact with the lever 35,
Machine operation is now stopped.

In the above configuration, the adjustment device 28 adjusts the position of the roller 26 and the adjustment bolt 37 of the stopper 36 adjusts the inclination angle of the container guide lever 30 in accordance with the size (diameter) of the container 22.
The balance weight 33 is selected so that when the container 22 gets caught and an abnormal force is applied to the container guide lever 30, the lever 30 can rotate clockwise. I'll keep it.

The container 22 is sent forward by the roller 26 at a speed faster than the transport speed of the carrier 21. In the discharge section 23, the rear bottom of the container 22 is connected to the roller 26.
When separated from the outer periphery of the container 22, the front body of the container 22 falls downward under its own weight while being received by the top 32a of the container guide 32. At this time, there is a gap between the rear body of the container 22a and the outer periphery of the roller, and the action surface 40 of the container pushing cam 39
The bottom of the container 22a is received by the container 22a. (See the dashed line in FIG. 2.) Next, the container 22b is guided by the container guide 32 and the container push cam 39.
is placed on the platform 41. (Second
(See the two-dot chain line in the figure) Furthermore, the container 22b is pushed onto the conveyor 43 by the action surface 42 of the container pushing cam 39.

In the above, when the container 22 gets caught between the roller 26 and the container guide 32 and becomes in an abnormal position, when the container guide lever 30 is rotated clockwise, the lever 35 is also rotated clockwise, and the limit switch 44 will operate and stop the machine.

Therefore, according to the embodiment described above, water droplets that move from the container 22 etc. to the bottom guide 24, flow by gravity, and reach the vicinity of the discharge section 23 are transferred to the rollers 26.
Due to the centrifugal force and gravitational force generated as the roller 26 rotates, the water droplets A that have moved to the roller 26 are formed on the outer periphery of the roller 26, which has a larger outer diameter than the V-shaped groove 26a and is located below the gravity. Move to section.

At this time, since the width of the opening of the V-shaped groove 26a of the roller 26 is wider than the outer diameter of the mouth of the container 22,
Even if the water droplet A that has moved to the outer periphery of the roller 26 falls, it will not enter the container 22.

In the above embodiment, since the container falling interval is adjusted by adjusting the inclination angle of the guide lever 30 by adjusting the adjustment device 28 and the adjustment bolt 37 depending on the size of the container, the adjustment range becomes larger and the guide Since the lever 30 is designed to be able to rotate when overloaded, it can sufficiently cope with increased processing capacity, and the container guide lever 30 is also designed to be able to rotate to stop the machine in the event of an abnormality. ,
There is also the added benefit of eliminating risks such as damage and breakage of containers and damage to machinery.

Further, in the above embodiment, the position of the roller 26 can be adjusted by the adjusting device 28, but the position of the roller 26 may be fixed, and in this case, the adjusting device 28 is not required.
