Abstract

PURPOSE:To enable printing extending over two mutually contacted flat surfaces by one process, by printing a bottle so that one flat surface, corner parts and other flat surface of a bottle are successively contacted with a screen in connec tion with the sliding of a squeeze. CONSTITUTION:When a liner moves to the left, a squeeze and a hook lever 47 move to the left. A hook 60 is not contacted with a cam plate 70 until the squeeze 13A completes the sliding on a printing flat surface X and contacted with said cam plate 70 in a moment when reaches a region Z. The cam plate 70 rides on the flat surface 61 of the hook 60 and moves along with the hook 60. Now, when a connection lever 50 revolves counterclockwise, a swingable arm 23 and a bottle receiver 23 are swung clockwise and a printing flat surface Y is contacted with a screen 10. Because the bottle receiver 23 is swung to a clockwise direction in matching relation to the squeeze passing in the vicinity of an area B, the region Z is printed. After swinging, because the printing flat surface Y is held in the state contacted with the screen 10, the squeeze 13 is moved to an area C to also print the Y-surface.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a printing device for a deformed bottle whose peripheral surface has a plurality of flat surfaces.

(Prior Art) A conventional foot print device includes a bottle holding mechanism that statically holds the bottle, a horizontally stretched screen that descends horizontally from above the bottle, and a screen that slides horizontally on the surface of the descending screen. This mechanism consists of a moving squeegee, a bottle holding mechanism holds the bottle with the printing surface facing up, a screen impregnated with ink is brought into contact with the printing surface, and the squeegee is run over the screen to print.

(Problems to be Solved by the Invention) In the above-described mechanism, if one sliding of the squeegee on the screen is defined as one step, one step is required for each printing plane. Therefore, in order to print continuous characters, figures, etc. over two planes, two steps are required, and it is also necessary to change the position of the bottle for each step. Furthermore, it is almost impossible to print a part of a character, figure, etc. on a corner where two planes meet, because printing misalignment is inevitable when the position of the bottle is changed.

(Objective of the Invention) An object of the present invention is to provide a printing device that is capable of printing continuous characters, figures, etc. over two adjacent printing planes including corners in one step.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a horizontally suspended screen that can be raised and lowered, a squeegee that can be raised and lowered together with the screen, and a squeegee that can be slid in one direction on the surface of the screen. In a printing device having a squeegee sliding mechanism that moves the bottle body, and a tough body holding mechanism that holds the bottle body; A rotating shaft with its center oriented horizontally, a swinging arm fixed to the end of this rotating shaft on the screen side in a direction perpendicular to the shaft, and a corner part attached to the swinging arm where two printing planes touch. The bottle holder is held in line with the axis center line of the rotating shaft, so that one printing plane rotates from a horizontal state to a horizontal state by rotating around the rotating shaft and the other printing plane swings to a horizontal state. An interlocking mechanism for swinging the bottle receiver in the sliding direction of the squeegee is interposed between the rotating shaft of the rigid body holding mechanism and the sliding mechanism of the squeegee; A cam mechanism is provided that swings the other printing plane so that it comes into contact with the screen in accordance with the sliding speed of the squeegee when the screen passes through one printing plane.

(Function) In conjunction with the sliding of the squeegee, the rotating shaft of the rigid body holding mechanism rotates, and the bottle held in the bottle holder moves from one printing plane to the corner where the two printing planes touch. Then, printing is performed sequentially on the other printing plane while being brought into contact with the screen.

(Example) Hereinafter, the present invention will be explained using a hexagonal deformed layer shown in FIG. 1θ and FIG. 11 as an example. For convenience of explanation, one adjacent plane (left side in the figure) is referred to as the printing plane X, the other plane (right side in the figure) is referred to as the printing plane Y, and the corner where the mark printing field and Y touch is the placement Z. . Microscopically, the in-vehicle Z has a curved surface.

In FIG. i1, 10 is a screen, which is long in the front-back direction of the drawing, and both ends of the screen are supported horizontally by arms 12 of a screen holder 11. 1
3 is a squeegee, and the squeegee is held in a squeegee holder 14, descends onto the screen 10, and slides on the upper surface of the screen in one direction. This sliding is performed by a squeegee sliding mechanism (not shown). During printing, the screen 10 and squeegee 13 are lowered to a position where the screen 10 touches the printing object. The drawing shows the screen in a standby state before printing. 10, the squeegee 13 and the squeegee sliding mechanism are well-known mechanisms.

Reference numeral 20 denotes a rigid body holding mechanism that holds the bottle, which is the object to be printed.

The rigid body holding mechanism 20 includes a rotation shaft 21 supported horizontally,
A swinging arm 22 hanging from one end of the rotating shaft 21;
It has a bottle receptacle 23 that is vertically slidably mounted on the front side (right side in FIG. 1).

The rotation shaft 21 is rotatably supported by a support member 25 fixed to a pedestal 24. The 0-rotation axis 21, which is set perpendicular to the squeegee sliding mechanism (right side in Figure 1), is an interlocking mechanism that links the 0-rotation axis 21, which rotates in conjunction with the sliding movement of the squeegee 13, and the squeegee sliding mechanism. will be described later.

In FIG. 2, the m-working arm 22 is fixed to the front side of the rotating shaft 21, that is, to the end on the screen 10 side. Swing arm 22
There is a groove 26 with a U-shaped cross section that is open on the front side.

This groove is bored in a direction perpendicular to the axis center line, and the slide member 27 is fitted therein. The slide member 27 has a screw hole 28 on the front surface thereof for fixing the bottle receiver 23.

The screw holes 28 are arranged at equal intervals in a direction perpendicular to the axis center line.

An adjustment screw 29 for adjusting the sliding movement of the slide member 27 with respect to the groove 26 passes through the lower end wall of @26 and is screwed into the slide member 27 from its lower end. This slide member 27 is provided with a female thread (not shown) corresponding to the adjustment screw 29.

Therefore, the slide member 27 can be finely adjusted in the vertical direction by operating the adjustment screw 29. Reference numeral 30 in the figure is a fixing screw for fixing the slide member 27 to the groove 26. The screw 30 is screwed into the side surface of the groove 26 so as to come into contact with the slide member 28 .

The bottle receiver 23 is removably fixed to a screw hole 28 on the front surface of a slide member 28 from the open side of the groove 26 of the swing arm 22.

The bottle receiver 23 has a tray portion 31 that holds the footwear that is the object of printing.
The plate portion is shaped to match the shape of the side surface of the footwear body opposite to the printed surface.

In FIG. 3, the shoe body 32 is set on the dish part 31 of the bottle holder 23 by aligning the center line of the area Z (corner part) where the printing planes X and Y contact each other with the axis center line. Match one printing plane
is brought into contact with the back surface of the lowered screen 10. In the embodiment, a spring 33 is engaged with the lower end of the swinging arm 22, biasing the swinging arm in a counterclockwise direction, and a stopper 34 is disposed so as to come into contact with the side surface of the swinging arm 22. X is in contact with the back surface of the screen 10.

In order to align the center line of region Z with the axis center line, first insert the bottle holder 23 into the appropriate screw hole 28 of the slide member 27.
Firstly, the slide member 27 is fixed with the adjusting screw 29.
Do this by subtly sliding the

The position of the slide member 27 determined in this way is fixed with a screw 30 from the side of the swing arm 22.

Figure 3 shows the printing operation of the squeegee 13 and the bottle holding mechanism 20, with the squeegee 13 (A) at the movement start position, the squeegee 13 (B) at the shaft center position, and the squeegee 13 (C) at the movement completion position. be. The squeegee 13 is (A) → (B) →
Move in one direction at a constant speed in the order of (C). On the other hand, in conjunction with the movement of the squeegee 13, the bottle receiver 23 moves from a state in which the printing plane X of the footwear 32 is in contact with the screen 10 to a state in which the other printing plane Y is in contact with the screen 10, centering on the axis center line. oscillate. This swinging is performed when the squeegee 13 passes through the area Z. If you look at this from the area Z, the curved area Z moves as the contact point with the screen 10 moves due to the swinging, and the squeegee 13 always moves to the contact point. It will swing at the speed at which it is positioned above.

Next, the interlocking mechanism between the rotating shaft 21 of the bottle holding mechanism 20 and the squeegee sliding mechanism will be described.

In FIG. 2, a gear 40 is coaxially attached to the other end of the rotating shaft 21, and a rack gear 41 placed horizontally from below meshes with this gear. The rack gear is supported by a rod 42 vertically attached to its lower surface so as to be slidable in the longitudinal direction. This rod 42 is loosely fitted into one end of a lever 44 whose center is pivotally connected to a machine base 43, and the other end of the lever 44 is attached to a slide plate 44 placed parallel to the rack gear 41.
5, and the slide plate 45 is fitted into a guide 46 fixed to the machine stand 43. Above this slide plate 45 is a hook lever 47 parallel to the slide plate. The hook lever 47 is connected to a liner 49 fitted onto a shaft 48 parallel to the hook lever. The squeegee 13 is also connected to the liner 49 so as to slide at the same time. The liner 49 is driven to travel by a drive means (not shown). Therefore, as the liner 49 travels, the hook lever 47 and the squeegee 13 move simultaneously.

The hook lever 47 and the parallel slide plate 45 are connected by a connecting rod 50 in a parallel link manner.

In FIG. 4, the connecting rod 50 has a long hole 51 at its center, into which a pin 53 from a support 52 fixed to the machine base 43 is inserted and supported. The hook lever 47 and the connecting rod 50 are connected by a pin 54 protruding from the connecting rod 50.
is inserted into a long hole 55 in the longitudinal direction formed in the hook lever 47. On the other hand 1. The slide plate 45 and the connecting rod 50 are connected by fitting a pin 57 protruding from the slide plate 45 into a U-shaped hole 56 bored at the lower end of the connecting rod 50.

A hook 60 with a flat upper surface is connected to the connecting rod 5 on the hook lever 47.
It is protruded so as to intersect with 0. On the other hand, a cam plate 70 is provided at the end of the connecting rod 50 on the side of the hook lever 47, which can contact the side edge of the hook 60, and can ride on the flat surface 61 of the hook 60 while making contact. The cam plate 70 has a U-shaped lower side edge that engages with the hook 60.

Next, the relationship between the hook 60 and the cam plate 70 will be explained. When the printing plane X of the duct 32 is in contact with the screen 10 as shown by the solid line in FIG. 3, the hook 60 and the cam plate 70 are It is located away from the plate 70 in the right direction in the drawing. Third
The state shown by the solid line in the figure and FIG. 4 is the state before printing starts.

Note that the screen 10 and squeegee 13 in FIG. 3 are also in a state in which the casing 32 is set in the dish portion 31 of the bottle receiver 23 and then lowered. This state before the start of printing is maintained by a spring 33 that pulls the swinging arm 22 counterclockwise and a sp) -/pa 34 that touches the side surface of the swinging arm 22. Instead of the spring 33, the swing arm 2 is attached to the rack gear 41 as shown in FIG.
2 may be provided by locking a spring 59 that pulls the hook lever 47 counterclockwise.Of course, the spring 33 and the spring 59 may also be used together, or alternatively, as shown in FIG. The elongated hole 55 may be formed so that the pin 54 of the connecting rod 50 is regulated by the left edge of the elongated hole 55 of the hook lever 47 when the hook lever 47 is completely extended in the direction.

In the embodiment, the spring 33, the stopper 34. spring 59 and
A means for regulating the pin 54 with a long hole 55 is also used.

The start of printing begins with the liner 49 running to the left in FIG. When the liner 49 moves to the left, the squeegee 13 and hook lever 47 connected to it move in the same direction (
left). In FIGS. 3 and 4, the hook 60
is set on the hook lever 47 so that the squeegee 13(A) does not come into contact with the cam plate 70 until it finishes sliding on the printing plane X, and comes into contact with the cam plate 70 the moment it reaches the area Z.

When the hook 60 comes closer to the cam plate 70, the cam plate 70 is pushed leftward and the next moment it rides on the plane of the hook 60, and after riding on it, it moves on the plane 61 relative to the movement of the hook 60. sliding movement 1, therefore hook 60
The connecting rod 50 rotates counterclockwise after colliding with the cam plate 70 until it rides on the cam plate 70, and after riding on the cam plate 70, the connecting rod 50 maintains a state of rotating counterclockwise. Now, when the connecting rod 50 rotates counterclockwise, the slide plate 45 is pulled to the right according to the rotation.

The lever 44 rotates clockwise around the rotation axis,
The rack gear 41 is pulled to the left via the rod 42. As a result, the rotation shaft 21 connected to the rack gear 41 via the gear 40 rotates, and the swing arm 22 and bottle receiver 23 are rotated clockwise. The printing plane Y abuts the screen lO. In FIG. 3, as the squeegee 13 passes near CB), that is, the area Z, the bottle receiver 23 swings clockwise, so the area Z is printed. After the swinging, the printing plane Y remains in contact with the screen 10, so by moving the squeegee 13 as it is to (C), the Y plane is also printed.

When the squeegee 13 moves in the direction (C) and the Y surface is printed, the squeegee 13 and the screen 10 are retracted upward.

This evacuation operation may be performed by any known means used in conventional printing presses.

(Effects) Since the present invention is configured as described above, continuous printing over two adjacent planes, which was previously impossible, can be performed in one step.
