Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single piece hopper capable of accommodating various types of single pieces in a single piece printing machine.

Single-piece printing machines are used to print list prices on price tags attached to items such as clothing.

Price tags and the like that are printed by this type of printing machine are small and relatively thick single pieces, so the single pieces may warp. In addition, a thin string for attaching to clothing is usually attached in advance before printing. Furthermore, since it is printing a list price, etc., it is often necessary to print on a relatively small amount of single pieces of various sizes. For this reason, special measures are required for the feeding mechanism and the like.

First, the basic configuration of a single-piece printing machine proposed by the inventor of the present invention will be explained with reference to FIG.

A plate holder 1 is provided with a hopper 2, and the hopper 2 accommodates a large number of single pieces 3 such as price tags. The hopper 2 consists of a positioning member 2a, a bottom plate 2b, and a rear presser plate 28. The single piece 3 is pushed up from below by the bottom plate 2b, and the positioning member 2a from above
It is positioned by From the rear, the single piece 3 is held down by a rear holding plate 28 for regulating displacement. Among the single pieces housed in the hopper 2, the uppermost single piece 3 is sent to the plate holder 1 via a hopper gate 5 by a single piece feed claw 4. Hotupa Gate 5
In this case, feeding of two pieces of single piece 3 is prevented. Plate holder 1
A printing head 6 that moves up and down with respect to the plate holder 1 and an ink tray 7 that moves forward and backward into the movement space of the printing head 6 for each printing are provided above. The print head 6 transmits the rotation of the motor to an output shaft via a gearbox, clutch, etc., and is moved up and down under the control of a disc-shaped control cam provided on the output shaft. The printing head 6 is loaded with a cheese box for holding rubber type and the like. Similarly, the ink tray 7 controls the output of the motor with a control cam, and via a link mechanism,
being moved from side to side. The printed single piece is received in the single piece receiving device 8.

Next, the operation of the single-piece printing machine described above will be explained. The single piece 3a in the uppermost position is conveyed to the plate holder 1 by the feed claw 4, and is ready for printing (FIG. 1a).

The ink tray 7 advances into the moving area of the print head 6,
The characters 6a of the check box of the printing head 6 are brought into contact with the ink tray 7, and so-called inking is performed (FIG. 1b).

When the ink tray 7 is retracted, the print head 6
is lowered and the single piece 3 placed on the plate holder 1
A is printed (FIG. 1c).

When printing is completed, the printing head 6 is raised, and the single piece 3b to be printed next is sent by the feeding claw 4, and the printed single piece 3a is pushed by the single piece 3b and stored in the single piece receiving device 8. (Figure 1d).

Since such single-piece printing machines mainly print price tags, there are single pieces of various sizes and thicknesses depending on the type of product.

Therefore, the single piece hopper 2 must be able to accommodate single pieces of various sizes without causing any displacement. In addition, since the single piece at the highest position in the single piece hopper 2 is sent to the printing position on the plate holder 1 by the feed claw 4, the single piece storage position of the single piece hopper 2 does not correspond to the printing position. I have to use it.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a single piece hopper for a single piece printing machine that can accommodate single pieces of various sizes in a manner that corresponds to the printing position on the plate holder so that single pieces of various sizes can be fed out.

In order to achieve the above object, the single-piece printing machine according to the present invention has a single-piece hopper from which a large number of single pieces are pushed upward and the position of the uppermost single piece is regulated by a positioning member. In a single piece hopper of a single piece printing machine, the uppermost single piece is transferred by a feeding claw to a printing position determined by the first side and rear edge of the single piece on a plate holder for printing. a rear presser plate movable back and forth for determining a rear reference position at the rear of the single piece; The first side of the single piece is controlled by a reference piece that is movable in a direction parallel to the rear presser plate and a side regulating rod that is installed at the tip of a lever that is pivotally supported on a fixed part. The side regulating member is rotatable in the direction of pressing against the reference piece.

According to the above structure, the object of the present invention can be completely achieved.

Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like.

2, 3, and 4 are a plan view, a front view, and a side view of an embodiment of a single-piece hopper of a single-piece printing machine according to the present invention.

A shaft 11 is screwed to the center of the base 10, a side regulating lever 13 is rotatably inserted into the shaft 11, and is locked in the axial direction by a locking ring 12 via a leaf spring 14. ing. Side regulation lever 1
A side regulating rod 15 is screwed to the tip of 3. This side regulating lever 13 is rotatably operated by an operating portion 13a provided at a substantially right angle to this side regulating lever 13.

A side plate 16 is erected on the base 10, and the side plate 16 is provided with a narrow window 16a and a notch 16b. A crank-shaped rear presser lever 17 is rotatably inserted into the narrow window 16a, and is axially locked to the shaft 11 via a leaf spring 20 with locking rings 18 and 19. A shaft 21 is mounted on the rear presser lever 17. Frames 22, 22 are provided at the edges of the notch 16b, and a sliding plate 23 is provided between the side plate 16 and the frames 22, 22.
has been inserted. A rear presser plate 24 of a single piece 3 is integrally provided on the sliding plate 23, and a fixing portion 26 of the rear presser plate 25 is integrally fixed to the slide plate 23 with screws. The fixing portion 26 has a tongue portion 27 extending horizontally from below, and the shaft 21 of the rear presser lever 17 is inserted into a long groove 27a provided in the tongue portion 27. A frame 24 is attached to the rear presser plate 24.
a, 24a are provided, and a reference piece 28 for regulating the first side of the single piece 3 is inserted, the reference piece 28 can be pulled out, a reference position can be determined, and it can be fixed with a screw 29.

The side adjustment lever 13 is rotatable by an angle θ like the side adjustment rod 15 shown in broken lines in FIG. , the side reference position is set. Since the side regulating lever 13 is pressed axially against the shaft 11 by a leaf spring 14, it can be fixed at any position. It is therefore possible to accommodate different single pieces in a reference position.

The rear presser plates 24 and 25 are similarly movable by a length l in the direction indicated by the broken line in FIG. This is done by moving the tongue portion 27 that engages with the shaft 21 of the presser lever 17 and causing the sliding plate 23 to slide.

As explained in detail above, according to the present invention, it has become possible to accommodate single pieces of various sizes in a manner that corresponds to the printing position on the plate holder so as to be able to be sent out.
