Description

Description: TECHNICAL FIELD The present invention relates to a can transport device for transporting a can to a place where printing is performed on the can.

2. Description of the Related Art Conventionally, as a transfer device of this type, a device having a duct for guiding a can and a blower for supplying air in a direction in which the can is transferred into the duct is known.

[Problems to be Solved by the Invention] However, in the above can transporter, the temperature of air transporting the can changes due to a change in temperature due to seasons such as summer and winter or a change in temperature such as morning and evening. Accordingly, there is a disadvantage that the temperature of the can changes, and the degree of biting of the ink during printing varies.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a can transport device capable of transporting a can at a constant temperature to a printing place.

Means for Solving the Problems In order to achieve the above object, the present invention is a device for transporting cans to a place where printing is performed on the cans, wherein a duct for guiding the cans, and In a can transfer device including a blower that sends air in a direction in which the can is transferred, a part of the duct is provided with a constant temperature blower that supplies air at a constant temperature and transfers the can. .

[Operation] In the present invention, the temperature of the can becomes constant by the air of a constant temperature supplied from the constant temperature blower, and the can is sent to the printing place. For this reason, printing is performed on a can at a constant temperature, the drying time of the ink and the like are constant, and the degree of biting of the ink in the can is constant.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In FIGS. 1 and 2, 1 is a can C by air.
And 2 is a constant temperature transfer duct connected to the end of the duct 1 on the printing location side. Duct 1
The constant temperature transfer duct 2 has a rectangular cross section, and a rail 3 for guiding the body of the can C is provided inside the side wall.

Further, the constant temperature transfer duct 2 is moved downward 1 /
4 It is curved in an arc shape, and the bottom C1 of the can C
Is to be guided. As shown in FIGS. 3 and 4, the upper wall 5 of the constant-temperature transfer duct 2 has a plurality of through-holes 5a formed at equal positions from the center line in the width direction at equal intervals. The upper surface of the wall 5 is provided with the through hole 5a.
A guide member 6 for guiding air to the outside is provided. The guide member 6 is made of a plate material made of tetrafluoroethylene resin having a thickness of about 10 mm, and is attached to the upper surface of the upper wall 5 in close contact therewith. The guide member 6 has an air guide hole 6a inclined at a position corresponding to the through hole 5a in a direction in which the can C is conveyed. These guide holes 6a are formed to be inclined at an angle of about 70 ° with respect to the plate surface when the guide member 6 is in a flat state. In addition, on the upper side of the upper wall 5, a 1/4
An air supply chamber 7 formed in an arc shape is provided, and an air inlet 7a for air to the air supply chamber 7 is formed on a side wall constituting the air supply chamber 7. This inlet 7a
The bellows hose 8 and the bendable spiral tube 9 are connected to a hot air blower (constant temperature blower) 10.

The hot air blower 10 includes an air filter 11, a blower 12 that sucks air from the air filter 11, and a blower 12
And a box 14 for supplying heated air flowing out of the air heating device 13 to the spiral tube 9. The air heating device 13 can set the heating temperature of the air to a predetermined temperature. The set temperature varies depending on the season, but the can C sent from the constant-temperature transport duct 2 to the printing place is different. It is preferable that the temperature is set to 30 ° C. to 35 ° C. This is because when the temperature of the can C is 30 ° C. to 35 ° C., the bite of the ink is best. Also,
The box 14 is for branching the heated air to the spiral pipe 9 and other pipes. A heat insulating material 15 is provided around the box 14 and the spiral pipe 9.

In the pipe transport device configured as described above, the deep-drawn can C is cleaned, and then sent to the printing location in the next step through the duct 1 and the constant-temperature transport duct 2. At this time, heated air flows from the hot air blower 10 into the air supply chamber 7, and the heated air further flows through the guide hole 6 a of the guide member 6 and the through hole 5 a of the upper wall 5 to transfer the constant temperature transfer duct 2. Flows into. The heated air that has flowed into the constant-temperature transfer duct 2 flows obliquely into the can C from the opening of the can C to be transferred, so that the fluid force of the heated air is efficiently transmitted to the can C. At the same time, since the heated air circulates in the can C, the can C is efficiently heated. In this way, while the can C passes through the constant temperature transfer duct 2,
Heated to approximately 30 ° C to 35 ° C.

Then, printing is performed on the outer peripheral surface of the can C heated to the above temperature.

According to the transport device for the can C configured as described above, by adjusting the temperature of the heated air supplied from the hot air blower 10, the bite of the ink at the time of printing is best from 30 ° C.
Since the temperature of can C can be adjusted to a temperature of 35 ° C,
Even when the temperature changes in the season, morning and evening, etc., the biting condition of the ink can be maintained in the best condition.

Further, since the fluid force by the heated air can be efficiently transmitted to each can C and the can C can be efficiently heated, the flow rate of the air supplied from the hot air blower 10 to the constant temperature transfer duct 2 can be increased. Can be reduced, and the temperature of the air can be set low, which is extremely advantageous in energy saving.

Further, for example, when a through hole is formed on the center line of the upper wall 5 in the width direction, the air flowing out of the through hole tilts the can C, whereby the opening edge of the can C hits the through hole, and Although the can C may stop in that case, in the case of this embodiment, since the through-holes 5a are distributed to the left and right with respect to the center line of the upper wall 5, even if the can C is inclined. The opening edge of the can C does not hit the through-hole 5a, so that each can C can be transported smoothly.

In the above embodiment, the constant-temperature transfer duct 2
Although a constant arc transfer duct is shown in the drawings, it is needless to say that the constant temperature transfer duct may be a straight one or another curved one.

[Effects of the Invention] As described above, according to the present invention, there is provided an apparatus for transporting a can to a place where printing is performed on the can, wherein the duct guides the can and transports the can into the duct. And a blower for sending air in a direction in which the can is supplied, a constant-temperature blower for supplying air at a constant temperature and conveying the can is provided in a part of the duct. By the air supplied from the temperature blower, the temperature of the can carried out to the printing place can be kept constant. Therefore, a remarkable operation and effect can be achieved in that the temperature of the can can be maintained at the temperature at which the bite of the ink is the best, regardless of the change of the temperature such as season, morning and evening.
