Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a safety device for an article delivery device.
More specifically, the present invention relates to a safety device used in an article transfer device that transfers articles from a first conveyor to a second conveyor via a spanning board.

``Prior Art'' Conventionally, this type of safety device includes a first belt conveyor for conveying articles, a spanning plate provided at a position in front of the first belt conveyor in the conveying direction, and a connecting plate provided from the first belt conveyor to the spanning plate. a second belt conveyor for conveying articles supplied via the first belt conveyor, the spanning plate is provided movably in the conveying direction of the first belt conveyor and held at a predetermined position, and the spanning plate is displaced from the predetermined position. There is a known device equipped with a detector that detects the occurrence of an abnormality (Japanese Utility Model Application Publication No. 151221/1983).

In addition to the above-mentioned belt conveyor, there is also known a conveyor in which a plurality of slits are formed on the surface along the conveying direction (Utility Model Application No.
Publication No. 83326).

By the way, when a flat span plate is provided between the first belt conveyor and the second belt conveyor, a gap is formed between the conveyor and the span plate. There are problems such as the belt becoming more likely to get caught in the belt, becoming unstable and prone to falling over, etc., especially when the spanning plate is provided so as to be movable in the transport direction of the first belt conveyor to constitute the above-mentioned safety device. Since it is necessary to form a space between the spanning plate and the second belt conveyor for the amount of movement of the spanning plate, the above-mentioned problem is likely to occur in that area as well.

In order to improve this problem, it is conceivable to use a slit conveyor in which a plurality of slits are formed on the surface along the conveying direction. That is,
A first slit conveyor and a second slit conveyor are connected in series, and a bridge is provided between both slit conveyors, with both ends shaped like comb teeth and the comb portions slidably fitted into the respective slits. All you have to do is set up the board.

According to such a configuration, even if the comb-like spanning plate is provided so as to be movable in the conveying direction of both slit conveyors to constitute the safety device,
Since it is possible to prevent gaps from being formed in the conveying direction between each slit conveyor and the spanning plate, the above-mentioned problems can be improved.

``Problem to be solved by the invention'' However, when the second conveyor is arranged to intersect with the first slit conveyor, it is not possible to use the comb-shaped span plate as described above. After all, it was necessary to form a gap between the spanning board and the second conveyor corresponding to the amount of movement of the spanning board.

``Means for Solving the Problems'' In view of such circumstances, the present invention includes a first conveyor for conveying articles, a span plate provided at a position forward of the first conveyor in the conveyance direction, and a connecting plate for conveying goods from the first conveyor to the front side of the first conveyor. a second conveyor for conveying articles supplied via a spanning plate, the spanning plate is provided movably in the conveying direction of the first conveyor and held at a predetermined position, and the spanning plate is displaced from the predetermined position. In the safety device for the article delivery device, which is equipped with a detector for detecting the occurrence of an accident, the second conveyor is arranged to intersect with the first conveyor, and a plurality of slits are provided on the surface of the first conveyor along the conveyance direction. A comb-shaped member is fixed to the machine frame of the second conveyor facing the first conveyor, and the spanning board is fixed to the frame of the second conveyor.
a plurality of rod-shaped members, one end of which is slidably fitted into each slit of the first conveyor, and the other end of which is slidably fitted into each gap of the comb-like member; Consisting of a supporting member that is connected and fixed as one body,
Further, the support member is provided so as to be movable forward and backward along the direction between the slit and the comb-like member.

"Operation" According to the above configuration, the second conveyor is connected to the first conveyor.
When the conveyors are arranged to intersect, even if a span plate is provided between both conveyors to constitute a safety device so as to be movable forward and backward in the transport direction of the first conveyor, There is no gap in the conveyance direction between the two conveyors and the comb-like members provided on the two conveyor sides, so that the articles can be smoothly conveyed.

Since the comb-shaped member is fixed to the machine frame of the second conveyor, the distance between the comb-shaped member and the second conveyor can be minimized, and therefore even in this part. Articles can be transported smoothly.

"Example" The present invention will be explained below with reference to the illustrated example.
In Fig. 1, a first conveyor 1 of a channel carrier type installed inside a container processing device such as a pasteurizer, warmer, or cooler is composed of a plurality of conveyors arranged parallel to each other and connected in a direction perpendicular to the conveyance direction. A large number of slits 3 are formed on the surface side of each channel 2 along the conveying direction so as to be located in a straight line between the front and rear channels 2.

A second conveyor 4 is disposed in the discharge section of the container processing apparatus, that is, in front of the first conveyor 1, in a direction perpendicular to the conveying direction of the first conveyor 1,
A transfer plate 5 for transferring articles from the first conveyor 1 to the second conveyor 4 is disposed between the first conveyor 1 and the second conveyor 4. This span plate 5 has a comb-teeth shape as a whole, including a large number of rod-like members 6 whose tips are positioned within the slits 3 of each channel 2, and a support member 7 that fixedly supports the base of each rod-like member 6. are doing.

The support member 7 of the spanning plate 5 is fixed to the tip of a swing plate 8 disposed below the upper running portion 4a of the second conveyor 4, and the swing plate 8 is
The lower end portions are pivotally connected to the upper ends of a pair of arms 10 that are pivotally supported on the machine frame 9, so that the arms 10 can move forward and backward in the transport direction of the first conveyor 1 in a substantially horizontal plane by swinging. . It goes without saying that a plurality of arms 10 are provided along the width direction of the first conveyor 1.

The machine frame 11 supporting the upper running part 4a of the second conveyor 4 has a first
A comb-teeth member 12 is fixed to one side of the conveyor, and each comb of the comb-teeth member 12 protrudes toward the support member 7 and is slidably engaged with a slit formed in the support member 7. By doing so, while allowing the spanning board 5 to move forward and backward, there is no gap between the spanning board and the second conveyor 4.

Further, a threaded rod 14 is pivotally supported at the tip of a lever 13 fixed to the lower end of the arm 10, and the threaded rod 14 is
4 through the machine frame 9 and connect the machine frame 9 and the threaded rod 14.
By loading a spring 16 between the nut 15 screwed onto the lever 13, the arm 1
0 counterclockwise and usually its arm 1
0 is brought into contact with a stopper 17, whereby the spanning plate 5 is normally biased and held at the predetermined position shown in the figure.

Further, an operating rod 18 is connected to the distal end of the swing plate 8, and the end of the operating rod 18 is brought into contact with a contact 20 of a detector 19 fixed to the machine frame 9, so that the span plate 5 swings. When the plate 8 and the operating rod 18 are moved to the right against the spring 16, the contact 20 is swung by the movement, and the detector 19 detects that the spanning plate 5 is moved to the right from the predetermined position shown in the figure. This makes it possible to detect displacement in either direction.

In the above configuration, normally the span plate 5 has a spring 1
It is held in the illustrated position by the biasing force of 6,
Articles (not shown) conveyed by the first conveyor 1 are transferred onto the second conveyor 4 via the spanning plate 5, and conveyed downstream by the second conveyor 4.

Then, when pieces of the article (not shown) are conveyed by the first conveyor 1 and are caught between the channel and the spanning board 5, the spanning board 5
When the pressing force applied to the spanning plate 5 exceeds the urging force of the spring 16, the spanning plate will be moved to the right. As a result, the operating rod 18 swings the contact 20 of the detector 19 to detect the displacement of the spanning plate 5 from a predetermined position, and when the displacement of the spanning plate 5 is detected by the detector 19, the necessary Accordingly, the operation of the article delivery device is stopped or an alarm is generated.

The above-mentioned spanning board 5 needs to have approximately the same length as the widthwise dimension of the first conveyor 1, but the spanning board 5 can be composed of a single or plural number of parts, and can be divided into a plurality of parts. In this case, the detector 19 may be provided for each spanning board so that each spanning board can move forward and backward independently.

Furthermore, it is clear that the rod-shaped member 6 and the support member 7 may be formed as a single piece.

"Effects of the invention" As described above, according to the invention, even when the second conveyor is arranged to intersect with the first conveyor, the distance in the conveying direction is smaller than that of the conventional method.
Since a safety device can be incorporated while maintaining a small size, it is possible to smoothly transport articles.
