Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a can transport device, and more particularly to a device for transporting cylindrical containers used for canned goods to a desired location using an air jet.

Prior art and its problems Japanese Patent Application Laid-open No. 55-119624 discloses a pair of elongated box-shaped air chambers arranged in parallel with a predetermined gap between them. ) and a horizontal bulkhead that interconnects both vertical walls.
The can bodies are housed in a letter-shaped channel with their central axis horizontal, and air jets are sprayed onto the end faces of the can bodies from a number of air injection nozzles provided on each vertical wall and inclined in the length direction of the channel to lift the can bodies into the air. An apparatus is described for floating and transporting the material along the channel to a desired location.

U.S. Patent No. 2,805,898 also describes two mutually opposing vertical walls of a pair of elongated box-shaped air chambers arranged in parallel with a predetermined gap, and a wall mounted at a low level in the gap. The can body is housed in a U-shaped channel formed by a top plate of an intermediate air chamber having an elongated box shape, and a large number of air jets inclined in the length direction of the channel are provided on each of these vertical walls and the top plate. A device is described for blowing a jet of air from a nozzle onto the can body to suspend the can body and transport it along the channel to a desired location.

In these prior art techniques, the can body is made to float inside the channel by means of an air jet and simultaneously propelled in a desired direction, resulting in a large amount of air being used.

Purpose of the invention The purpose of the invention is to provide two mutually opposing elongated box-shaped air chambers arranged in parallel with a predetermined distance apart.
By providing a track for rolling a cylindrical can body with a horizontal center axis on two vertical walls, we have created an economical air-driven can transfer device that eliminates the need for air for flotation of the can body. It is about providing.

The above object of the present invention is to provide a housing 1 consisting of a flat rectangular tube arranged horizontally, a pair of elongated box-shaped boxes arranged parallel to each other in the housing with their respective vertical walls facing each other with a predetermined distance apart. air chamber 2
a, 2b, and a pair of tracks 3a, 3b installed adjacent to and parallel to the lower end of the vertical wall of each air chamber, and each air chamber is supported horizontally on the pair of tracks. The can body is provided with a large number of air injection nozzles 20 that are opened in each vertical wall at a level higher than the height of the central axis of the can body and are inclined in the traveling direction of the can body on the orbit, and the can body being transported. This is achieved by the can body transfer device of the present invention, which is equipped with a distance adjustment mechanism for adjusting the distance between the air chambers for adjusting the vertical wall of the air chamber toward and away from the can body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the device of the present invention will be described below with reference to an embodiment shown in the accompanying drawings.

Referring to FIG. 1, a device 10 of the present invention is shown having a housing 1 consisting of a relatively flat horizontal square tube mounted on a base plate 15. 14 indicates the bottom wall of the square tube. A can body W, which is propelled by the device 10 of the present invention in a direction perpendicular to the plane of the drawing, is placed in the center of the interior of the housing 1 with its center axis XX being horizontal. A screw rod 5 arranged perpendicularly to the traveling direction of the can body W and parallel to the bottom wall 14 is connected to a pair of bearings 8.
It is rotatably supported on the bottom wall 14 by a and 8b. The end of the screw rod 5 protruding rightward from the right vertical wall of the housing 1 is connected to the drive shaft 11 via a bevel gear 9.

An elongated air chamber 2a having a rectangular cross section is arranged on the left side inside the housing 1, and a horizontal support plate 1 is attached to the bottom surface of the air chamber 2a.
A support ring 7 is attached via 2a. As shown in the figure, the support ring 7 is rotatably fitted into the non-threaded portion adjacent to the left end of the screw rod 5. Air chamber 2
A counterpart air chamber 2b having the same structure as a and cooperating with it is placed on the right side inside the housing 1,
A female thread member 6 is attached to the bottom surface via a horizontal support plate 12b. The female screw member 6 is the screw thread portion 5 of the screw rod 5.
It is screwed into T. Therefore, by rotation of the screw rod 5, the air chamber 2b moves horizontally relative to the air chamber 2a, and the distance between the pair of air chambers 2a, 2b can be adjusted. Although not shown, each air chamber 2
a and 2b are connected to a compressed air supply source through appropriate piping.

The horizontal support plates 12a, 12b attached to the lower ends of each air chamber 2a, 2b are connected to the opposite air chamber 2, respectively.
a, 2b, each projecting edge has a track 3a, 3 that supports the end of the can body W.
b is attached parallel to the traveling direction of the can body W.

Each air chamber 2a, 2b is attached to the vertical wall opposite to the vertical wall facing the end surface of the can body W, and the central axis of the can body W is attached to the upper part of each air chamber 2a, 2b.
It is provided with a large number of L-shaped support arms 13a, 13b extending parallel to XX and above the end of the can body W. Stopping members 4a and 4b placed above the pair of tracks 3a and 3b with the can body W in between are supported by a plurality of L-shaped support arms 130 and 13b, respectively. The restraining members 4a and 4b each extend parallel to the traveling direction of the can body W, and prevent the can body driven by the air jet described below from floating excessively.

Each air chamber 2a, 2b is equipped with a large number of air injection nozzles 20 opened in vertical walls 16a, 16b facing the end surface of the can body W. As shown in FIG. 2, each injection nozzle 20 is inclined in the traveling direction of the can body W by an angle α with respect to a straight line xx' passing through the opening and perpendicular to the vertical walls 16a, 16b. A large number of nozzles 20 arranged parallel to the traveling direction of the can body W at predetermined intervals are arranged on each vertical wall 16a, 16b at a level higher than the central axis XX of the can body W.
It will be opened in The value of the angle α is usually between 30° and 60°.
If necessary, the angle α can also be opened slightly downward relative to the direction of travel of the can body.

During operation, the distance between the two vertical walls 16a and 16b is adjusted in advance using the screw rod 5 to match the length of the can body W, and then the can body W is mounted on the pair of tracks 3a and 3b. However, when compressed air is injected from each air injection nozzle 20, the can body W can be rolled on the tracks 3a, 3b by the action of the air jet.

Effects of the invention The effect of the device of the present invention is that the can body W is simply rolled along the tracks 3a and 3b without being levitated in the air, so the number of air injection nozzles is significantly reduced and the manufacturing cost of the device is reduced. Not only is this possible, but the amount of air consumed can also be reduced, leading to savings in operating costs. Another advantage of the present invention is that it has a simple structure and can be manufactured at extremely low cost.
