In this embodiment, the guide body is constructed by connecting a cylindrical member (weight) that is slightly lighter than the container to be transported with a chain. It suffices if it can be moved to any other position, and it may be configured to be bendable and endless.
[0010]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic overall plan view of a container processing apparatus according to an embodiment of the present invention.
2 is a transport conveyor provided in the container processing apparatus 1, and 3 and 4 are juxtaposed on both sides of the transport conveyor 2, and the containers 5 in a collective state from a supply port 10 provided on the side of the transport conveyor 2 in the transport direction. 6 is a fixed guide provided on the supply conveyors 3 and 4 for guiding the containers to the transport conveyor 2, and 7 and 8 are discharge conveyors for discharging the containers 5 from the transport conveyor 2. The containers 5 supplied from the supply conveyors 3 and 4 are sprinkled with hot water or the like while moving on the transfer conveyor 2 and are subjected to processing such as sterilization, heating, and cooling.
[0011]
Next, specific examples of the overturn prevention device in the container transport device will be described in detail with reference to FIG.
In the figure, the transport conveyor 2 and the supply conveyor 4 are configured to transport containers from right to left, and a bendable endless guide body 13 is provided at the side end of the transport conveyor 2 at the supply port 10. A drive device 18 having a sprocket 15 that rotates and feeds the guide body 13 to the folded portion on the upstream side is disposed on the upstream side (right side in the drawing) and the downstream side (left side in the drawing). ing. The guide body 13 is sent out along the supply port 10 by the rotation of the sprocket 15 so as to circulate and rotate in the clockwise direction in the drawing, and the supply port 10 can be closed as shown in the figure by the propulsive force applied by the conveyor 2.
[0012]
As will be described later, since the sprocket 15 is set to send out the guide body 13 faster than the transport speed of the transport conveyor 2, the length of the guide body 13 is such that the supply port 10 can be closed in a zigzag state. Is set. The supply port 10 refers to an opening portion of a guide that allows the containers 5 to move from the supply conveyor 3 to the transport conveyor 2, and closing means closing this.
[0013]
Next, the detail of the guide body 13 is demonstrated based on FIG. 3, FIG. As shown, the following description is for the type in which the supply conveyor transports containers from left to right as opposed to that shown in FIGS. In the vicinity of the upstream end of the supply port 10, the endless guide body 13 is attached to a sprocket 15 provided horizontally on the transport surface of the transport conveyor 2. The cylindrical weight 11 is bent to form an endless shape, and the chain 12 is wound around the sprocket 15 to rotate. The sprocket 15 is driven to rotate at a predetermined speed by a motor 17, and the speed at which the guide body 13 is sent out is set to be higher than the transport speed of the transport conveyor 2. The folded portion on the downstream side of the guide body 13 is going to advance in the transport direction of the transport conveyor 2 at the transport speed of the transport conveyor 2 by the propulsive force given by the transport conveyor 2. As shown in FIG. 8, the guide body 13 that is sent out quickly proceeds in a zigzag state in which the weights 11 are arranged in a staggered manner.
[0014]
Based on FIG. 5, FIG. 6, the related structure of the sprocket 15 and the guide body 13 is demonstrated.
A chain guide 16 is provided at a portion where the chain 12 enters and leaves the sprocket 15, and guides the guide body 13 so as to be sent out along the supply port 10.
[0015]
Next, the contact prevention plate 14 will be described with reference to FIGS. 9 and 10. The endless guide body 13 that can be bent is rotated by the sprocket 15 of the driving device 18 with the chain 12 having the weight 11, and the forward path that travels from the upstream side to the downstream side on the conveyor 2 and the upstream side from the downstream side. The distance of the return path going to the side is narrowed by being pressed by a large amount of containers, and noise is generated by contact. In order to prevent this, a contact prevention plate 14 is provided between them. The contact prevention plate 14 is attached to a swing member 21 swingably provided on a support shaft 20 formed between positions where the guide body 13 of the driving device 18 enters and leaves, and is made of a thin resin plate. It is elastic and swings with the movement of the guide body 13 and is designed to bend.
[0016]
With the configuration as described above, when the container 5 in the assembled state is supplied by the supply conveyor 3 in the state of FIG. 2, the leading container 5 is guided by the weight 11 of the guide body 13, so When being pushed out onto the conveyor 2 by the container 5, it will not fall down even if it slips badly. Further, the weight 11 is pushed by the pressing of a large number of containers 5, and the entire guide body 13 is pushed obliquely with respect to the carrying direction of the carrying conveyor 2 to open the supply port 10. The leading end side (downstream folded portion) of the guide body 13 in the transporting conveyor 2 is going to advance in the transporting direction, so when the supply amount of the container decreases, the guide body 13 approaches the supply port 10, that is, the supply port 10 is moved in the closing direction. That is, the opening degree of the guide body 13 changes in accordance with the increase or decrease of the supply amount of the container 5.
[0017]
Next, the operation of the present invention will be described with reference to FIGS. 7 (A), (B), (C), (D), and FIG.
When the container 5 is supplied from the supply conveyors 3 and 4, the container 5 moves onto the transport conveyor 2 while pushing the weight 11 of the guide body 13 as shown in FIG. At this time, the container 5 does not fall down because it is supported by a weight 11 having a certain weight (slightly less than the weight of the container).
[0018]
Further, when the supply amount of the container 5 increases, the container 5 pushes the guide body 13 and the degree of opening increases as shown in FIG.
Next, when the supply amount of the container 5 decreases, when the feed speed of the guide body 13 is not faster than the transport speed of the transport conveyor 2, that is, the sent guide body 13 is not zigzag-shaped, When the conveyor belt 2 is always stretched by the propelling force of the conveyor 2, as shown in FIG. 7C, an open portion 19 is generated in the supply port 10, and the container pushed out of this portion may fall over. There is. However, the guide body 13 is sent out faster than the transport speed of the transport conveyor 2, and the guide body 13 is zigzag-shaped so that there is a margin in length, so that the container supply amount decreases as shown in FIG. The guide body 13 can move in the transport direction of the transport conveyor 2 to close the supply port 10 to prevent the occurrence of an open portion and prevent the container from overturning.
[0019]
【The invention's effect】
As a result of employing the above configuration, the present invention can obtain the following effects.
(1) Even if the container is supplied from the side in the transport direction, it can be prevented from falling.
(2) Even if the supply amount decreases, it can cope.
(3) Since a contact prevention plate is provided, noise is prevented.
