Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a can body having only one end necked in, and a can of different diameters with a can lid of different diameters wound up is retort sterilized and washed. After that, it is placed and transported on the conveyor in a mixed state, and the cartons are packed in the upright state with the orientation of the top and bottom aligned.The lid direction is set in the transport path from the conveyor to the carton packing device. The present invention relates to a device for arranging cans of different diameters.

(Prior Art) Conventionally, as a container alignment device for adjusting the opening direction of a container having one end face opened, for example, Japanese Patent Laid-Open No. 55-66419.
Apparatus for aligning containers described in Japanese Patent Laid-Open No. 60-20
A container alignment device and the like described in Japanese Patent No. 4516 are known.

The former conventional device utilizes the fact that the center of gravity of an empty container whose one end surface is open is eccentrically biased toward the closed side, so that the container is opened while being transported in the vertical can state with the lid facing sideways. Remove the container whose direction is different from the predetermined direction from the transport path,
Only the containers whose opening direction is the same as the predetermined direction are aligned.

Further, the latter conventional device also utilizes the uneven distribution of the center of gravity of the container having the opening, by vibrating and transporting the container in a valley-shaped passage that widens toward the end, so that the closing part on the center of gravity side is closed. The feature was that the container was oriented downward so that it was oriented vertically.

(Problems to be Solved by the Invention) However, in such a conventional container aligning apparatus, the center of gravity of the container is utilized because the center of gravity of the empty container with one end open is used. It could not be applied to a container filled with contents whose position, container and geometrical center position were substantially the same.

From this, it is not possible to align the top and bottom different diameter cans filled with the contents of the present invention in the lid direction, and conventionally,
The lid direction was aligned by hand. For this reason, the labor and work man-hours have increased, and a working space for aligning the lid directions has to be secured in the container manufacturing apparatus.

(Means for Solving Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this object, the apparatus for arranging cans of different diameters according to the present invention, The following means were adopted.

A canister with a different diameter in the upright position with a canopy winding part with a diameter larger than the can body diameter, and a can with a different diameter in the upside down condition with a canopy winding part with a diameter less than or equal to the can body diameter. A can chute having a wide carry-in part for carrying in the present state and a narrow carry-out part for carrying out a lid in a laterally-oriented vertical can state, and a can conveying path formed in a downward inclined state, The tip of the can chute in the latter half position of the can transport path is located above the can transport path and is approximately parallel to the can chute of the different diameter cans with a space slightly wider than the can body diameter and narrower than the diameter of the top winding clamp. One of the parts is inclined downward with respect to the other, and a pair of uppers that guide the cans of different diameters in the forward direction in the forward position in the latter half position of the transfer path from the loading position to the transfer position of the transfer path. The guide member and the upper position of the upper guide member on the side where the tip is inclined downward, A top guide member arranged with a space slightly wider than the height of the part, a position below the upper guide member, arranged with a width narrower than the can body diameter of a can of different top and bottom, from the carry-in position of the can transport path. The upper surface inclines downward to the side where the top guide member is present toward the intermediate position or the latter half position, and receives the upside down different diameter can at the loading position of the can transport path,
A lower guide member that guides the upside down different diameter can in a reverse direction from the carry-in position to the intermediate position or the latter half position, and a lateral position of the can conveying path of the can short, which opposes the top guide member. The width of the can transport path is gradually narrowed from the carry-in position to the intermediate position or the latter half position of the can transport path, and it is used as a canopy winding part when the upside-down can of different diameters rotates in the reverse direction. A rolling guide member having an inner surface that comes into contact with the rolling guide and an upper end surface that supports the rolling guide of the bottom cover and guides the rolling when the can of different diameters in the upright position rolls in the normal rotation direction. Is characterized by.

(Operation) Accordingly, in the apparatus for arranging the different-diameter cans of the present invention, by adopting the above-mentioned means, the cans of the different-diameter cans are divided into the upper and lower parts by utilizing the difference in the lid diameters. However, it is possible to arrange the cans of different diameters in which the tops and bottoms are mixed in different directions in a single row while the turning times and the turning directions are made different, and to align the lid directions while carrying their own weight.

That is, the upside-down cans of the upside-down and upside-down different-sized cans, which were loaded with the top / bottom lid facing upward, are divided into upper and lower parts, and the upside-down different-sized cans of the upside-down state are placed at the normal position. By changing the turning time, such as turning the different diameter cans in different states, it is possible to rotate the different diameter cans in the opposite direction by using the weight of the cans themselves filled with the contents. Therefore, the contact area with the guide member is reduced by that much, and the turning angle is 90
Since they can be aligned at a certain degree, it is possible to minimize damage caused by contact with the guide member.

Moreover, from the carry-in position to the carry-out position in the alignment device,
Since the lid directions can be aligned while the cans of different diameters are brought into contact with each other and are conveyed in a single row, the entire apparatus becomes compact and can be easily incorporated into an existing line.
