Next, the structure of the drying means 11 will be explained.

The drying means 11 of this embodiment is an ultraviolet irradiation device (hereinafter referred to as U
(referred to as a V irradiation device). This LJV irradiation device is arranged on the opposite side of the hole nut 187 from the heating means 7, and irradiates the side surface of the printed pallets 1 to 1 with ultraviolet rays to dry them.

The drying means 11 has a pole nut 1 similar to the conveying mechanism 7.

The height position can be adjusted, allowing for efficient drying and versatility.

As shown in FIG. 1, stopper mechanisms 221 are installed on the conveyance path of the pallet 1 at a plurality of locations (four locations in this embodiment).

The configuration of this stopper mechanism 221 will be explained below.

The stopper mechanism 221 has a configuration as shown in FIGS. 14 and 15. First, a slide member 225 is installed on the base 223 so as to be slidable in a direction parallel to the conveyance path of the pallet 1.

That is, a pair of kite members 227 and 227 are fixed at the lower end of the slide member 225, while the base 223

Above guy 1 part 227.227 or rail 229.22
9. It is slidably engaged.

In addition, a hole thread 2 is placed in a direction parallel to the conveyance path of the pallet 1.
A handle 233 is fixed to the pole head 231.

On the other hand, a ball nut 235 is screwed into the ball screw 231, and the already mentioned slide member 225 is fixed to this pole nut 235. Therefore, handle 2
By rotating the slide member 33 with an appropriate force of 1f, the slide member 225 can be slid in a direction parallel to the conveyance path of the pallet 1, thereby adjusting the stop position when the size of the pallet is changed. Can be adjusted.

A cylinder mechanism 237 is fixed to the slide member 225, and a rod 239 of the cylinder mechanism 237 is fixed to the slide member 225.
A pair of pins 243 and 243 are connected to each other via a connecting member 241.
are connected. And the above cylinder machine 'Wi23
7, the pair of pins 243, 24
3 is made to protrude from the direction perpendicular to the conveyance path of the pallet 1. This allows the transported pallet to be stopped at a predetermined position.

The operation will be explained based on the following configuration.

The pallet (1) is first transported to the printing position B by the transport means 3 with the surface to be printed facing upward. At this time, on the primary side of the printing position B, the surface to be printed is heated by a gas burner 7 and oxidized to improve the adhesion of the ink.

The barlet I fed by the printing position &B' ti is stopped at a predetermined position by a stopper machine [221]. Next, the support device 121 is turned forward toward the pallet, and the pallet 1 is held between the support plate 149 of the support device 121 and the support plate 157 arranged on the opposite side of the pallet.
Hold that position.

In this state, first, by operating the cylinder mechanism 191, the elevating member 195 is lowered to press the screen 215 against the surface of the pallet 1 to be printed.

Thereafter, the cylinder mechanism 209 presses the squeegee 214 against the screen 215, and the drive motor 199
The slide member 197 is caused to travel by driving. Thereby, predetermined screen printing is performed on the side surface of the pallet 1.

At this time, since it is not possible to print in the nook insertion hole on the side of the pallet, the cylinder mechanism 209 is driven at the position of the fork insertion hole to raise the squeegee 214.
The squeegee 214 is lowered again at the printing position, and the squeegee 214 is moved up and down again in this manner so that printing can be performed without delay.

That is, the cylinder mechanism 209 is driven in accordance with the stroke of the surface to be printed. Therefore, if there are three surfaces to be printed on the side surface of the pallet, the raising and lowering of the squeegee 214 is repeated three times by the drive of the cylinder mechanism 209, and if there are only one surface or the entire surface to be printed, the raising and lowering of the squeegee 214 is performed once.

In this manner, printing is performed by repeatedly raising and lowering the squeegee 214 while the slide member 197 is moved by the drive motor 199. Therefore, the type of palette (
It is possible to print regardless of the number of printing locations, such as a 2-way pallet or a 4-way pallet, and has sufficient versatility.

Note that the height position of the screen 215 is adjusted in advance according to the size of the pallet 1 by operating the handle 181.

When printing is completed, the pallet 1 is released from the holding state by the support device 121 and the stopper mechanism 221, and is transported by the transport means 3 to the drying position C (1h). On the secondary side of
The printed surface is irradiated with ultraviolet light by the LJV irradiation device 11, and the printed surface is dried.

After the pallet 1 is transported to the drying position C by the transport means 3, it is returned to the reversing position A.

At this reversal position A, it is rotated to orient the next surface to be printed upward.

That is, the pallet 1 returned to the reversal position A is moved forward by the support plate 7 of the rotating device 41 driven by the cylinder mechanism 53.
3 and the support plate 73 of the support device 43, which is moved forward by the drive of the cylinder mechanism 107. In that state,
A claw member 89 attached to the support plate 73 on the side of the support device 41
is rotated by the cylinder mechanism 95, and the pallet is
-1 is firmly connected to the through hole. As a result, the pallet 1 is fixed to the support plate 73 side.

Next, the supporting device 43 side is moved backward, and the pallet 1 is held only on the rotating device 41 side. Next, the drive motor 61 is driven to drive the support plate 41. That is, the bullet 7 is raised by a predetermined amount. This is to enable rotation of the pallet 1-1.

Next, the drive motor 81 is driven to rotate the pallet 1 by a predetermined angle (for example, 90 degrees). Next to the rotation, the pallet 1 is lowered, and the cylinder mechanism 95 is driven to release the engagement of the claw members 89, thereby releasing the holding by the rotating device 41.

The pallet 1 is now in a state with the next printing target surface facing upward, and is transported to the printing position B by the transport means 3, and the same steps as described above are repeated.

Thereafter, the same process is repeated until the predetermined screen printing is performed on all printing target surfaces of the pallet 1.

In addition, in these series of steps, a plurality of stopper mechanisms 2
21 functions at a predetermined timing.

According to this embodiment, the following effects can be achieved.

First, all the printing work that was previously left to manual labor can now be done automatically, improving work efficiency and reducing costs.

Further, even if there are many surfaces to be printed on the pallet l-1, the printing can be done automatically by appropriately rotating the pallet 1 using the reversing means 5, which is extremely efficient.

(Effects of the Invention) As detailed above, according to the part l-printing device and pallet printing method according to the present invention, the printing work on the sides of the pallet can be performed automatically, thereby improving work efficiency. I can do it.

Furthermore, since each mechanism is configured to have versatility, it is possible to cope with changes in the size and type of pallets, thereby improving productivity and reducing costs.

Furthermore, good and stable printing is possible.
