Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder depositing device for embossing.

[0002]

2. Description of the Related Art Conventionally, an embossing process is performed to make a printed portion such as a character printed on a business card or a postcard swell, but before the ink is dried by printing on the embossed portion, the paper is manually It is practiced to put it in and remove it from the powder for embossing, and blow it off to remove excess powder, and then put it in an embossing device that automatically heats and ventilates. However, although the operation of putting the powder in the powder for embossing or removing the powder is troublesome, there has been no practical device for automatically performing this.

Embodiments of the present invention will be described below with reference to the drawings. In the embodiment of the present invention shown in FIGS. 1 to 5, 10 is a main body. Reference numeral 12 denotes a paper feeding device provided at one end of the main body, and a paper 90, which is formed by stacking business cards or postcards, is printed on a portion to be subjected to a floating process, and ink is not sufficiently dried. The rear end portion is supported by the support member 14 by engaging with the pair of protrusions 13 protruding in the direction. Reference numeral 15 denotes a suction member that can be moved up and down by a means (not shown). When the suction member 15 is raised, it is vacuum sucked from the hose 17 to suck the paper 90 and while descending, the sucked paper is removed from the protrusion 13 It is designed to be repeated.

Reference numeral 18 denotes a powder supply device, which is constructed as described below. That is, reference numeral 20 denotes a conveyor, which receives the paper 90 supplied from the paper feeding device 12 by a plurality of endless members 21 composed of, for example, a spiral spring and advances it. A powder feeder 22 ejects the powder 91 onto the paper 90. The container 23 stores the powder 91, and the holder 26 holds the powder 91 dropped from the hole 25 of the container.
have. Reference numeral 27 is a jet port formed in this holding portion. 28 is a hose leading to a compressed air source (not shown),
It is connected to the holding portion 26 via a solenoid valve 30.

Reference numeral 31 is a detector for irradiating light and detecting the state where the paper 90 delivered by the conveyor 20 reaches below the powder feeder 20 by reflected light. Paper 90
When is detected, the electromagnetic valve 30 is automatically energized and the powder 91 held in the holding portion 26 is ejected through the ejection port 27. In this case, the powder 91 ejected onto the non-dried portion of the printed ink firmly adheres to the ink, and the powder 91 ejected onto the other portion adheres removably and lightly onto the paper 90.

32 is extra powder 91 deposited on the paper 90.
Is a device for removing the liquid and is configured as described below. That is, 33 is an electric blower that blows the paper 90 sent out from the conveyor 20 so as to be substantially upright and downward at a considerable speed, and 35 and 36 are the paper 90.
And 37 is a conveyor having a plurality of endless members 38 composed of spiral springs for receiving and transferring the paper 90 falling downward. As shown in FIG. 4, the falling paper 90 having a substantially upright speed is sandwiched between the endless members 38 and engaged with each other to be transported while maintaining a substantially upright state. The endless member 38 constitutes a holding means for the paper 90.

Reference numeral 40 denotes the paper 9 which is transported in this upright state.
It is a brush-off member made of, for example, a thin steel plate that hangs from above so as to be able to contact 0. When the paper 90 transported on the conveyor 37 comes into contact with the brush-off member 40, when the paper 90 and the brush-off member 40 both bend and separate, the paper 90 returns and the excess powder 91 is brushed off. The powder 91 is satisfactorily removed by repeating a plurality of times. Reference numeral 41 denotes a roller at the tip of the conveyor 37, and a detaching member 42, which is adjacent to the endless member 38 and has a large diameter up to the position of the outer circumference of the endless member, is wound and fixed. Therefore, the paper 90 will be automatically removed from the conveyor 37 when it reaches the delivery end. Reference numeral 43 is a guide plate that abuts the paper 90 so as to fall in a predetermined direction.
The paper 90 that has exited from the scraping device 32 automatically enters the next embossing device (not shown).

Various modifications can be made to the above embodiment. For example, the sheet feeding device 12 may be changed to another known type different from the one illustrated and described,
Alternatively, the paper 90 coming out of the printing machine may be automatically supplied without providing a paper feeding device. Further, the powder supply device 18 may be configured such that the container containing the powder is vibrated without being ejected by air and the powder is dropped from the hole. Further, the endless member 21 of the conveyor 20 in the powder supplying device 18 may not adhered powder 91 by using the helical spring, but such as those made of made objects or the V-belt than without example ropes being limited thereto various Can be changed. Further, the scrubbing member 40 can be replaced with, for example, a spiral spring, or can be replaced with a rigid member. In the case of a rigid member, the range in contact with the paper 90 can be reduced or the conveyor can be used. It is necessary to reduce the transfer speed of 37.

[0011]

[0012]

Since the present invention is constructed as described above, the powder 91 is automatically adhered to the portion of the paper 90 to be subjected to the lifting process, and the powder 91 is extremely excellent from other portions.
Significantly reduce the effort and time to be able to shake off the real
It has the effect of being highly versatile . this
In the invention, the removing member 40 is provided in a plurality of stages.
Better powder provided or made of thin steel plate
91 can be paid off.
