Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printing machine for pottery painting that transfers a pattern engraved on a printing plate to a ceramic material by a transfer pad that alternately abuts the printing plate coated with ink and the ceramic material.

[0002]

[Prior Art]

 As means for alternately contacting the transfer pad with the printing plate and the ceramic material, the transfer pad can be reciprocally moved horizontally between the positions where the printing plate and the ceramic material are arranged, or the printing plate and the ceramic material can be placed under the transfer pad. There are two ways to position the materials alternately. In either case, it is necessary to align the transfer pad, the printing plate and the ceramic material with each other accurately (including the posture). Especially in the case of multi-color printing, color misregistration occurs if the positions of all printing plates coated with different color inks do not match, so the adjustment is delicate. Conventionally, a slider mechanism that is independent of the ink tray in the X and Y directions and a rotation mechanism that changes the angle of the ink tray are overlapped between the ink tray on which the printing plate is set and the table. The slider mechanism is provided with a handle for screw-feeding the ink tray in the X or Y axis direction, and the rotating mechanism is provided with an adjusting handle for changing the angle.

[0003]

[Problems to be solved by the device]

 Conventionally, since the two-way slider mechanism and the rotation mechanism for angle correction are each provided with a feed and adjustment handle that directly operates each mechanism, the positions of these adjustment handles are different regardless of the operation position. Therefore, it is necessary to move the operation position each time adjustment is made, and even if the plural units are arranged side by side in order to perform multicolor printing, even the movement to the opposite side is not left. Further, since the slider mechanism and the rotating mechanism for changing the angle which are independent in the X and Y axis directions are interposed between the table and the ink tray in a stacked state, there is a drawback that the size is complicated and the size becomes large.

[0004]

[Means for Solving the Problems]

 The present invention is a printing machine for pottery painting which improves the operability of position adjustment work of a printing plate, and its construction is such that an ink tray on which the printing plate is set is attached to the table on the X-axis and Positioning means for rotating and moving in the Y-axis direction is provided, and the operation portion of the positioning means is centrally arranged at one place of the table, and the positioning means is the center of the side of the ink tray orthogonal to the X-axis. A pressing member that presses the position in the X-axis direction, a pressing member that presses in the Y-axis direction to the left and right positions of the side orthogonal to the Y-axis, and a pressing member that is opposite to the mounting position of each pressing member in the ink tray. A biasing member for pushing back the ink tray against the direction is provided, and the operation knob for adjusting the amount of extension of each pressing member and each pressing member are connected through a remote control wire. ..

[0005]

[Action]

 Since the operating portion of the positioning means is centrally arranged at one place of the table, the positioning means can be operated from one place of the table. Also, the effective arrangement of the pressing member and the urging member allows the positioning means to be laid out on the same plane, which makes the device thinner, and the remote control wire can be used to freely select the operation position.

【Example】

 A printing machine for painting ceramics according to the present invention will be described with reference to the drawings. In the printing machine for ceramics painting of the embodiment, as shown in FIGS. 2 and 3, two sets of two printing units are horizontally arranged side by side, and each set has two sets operating simultaneously and two plates at a time. It is possible to transfer to 3 colors. In each printing device, as shown in FIG. 3, transfer pads 1 that can be moved up and down are arranged above the transfer position, and a copper plate 2 as a printing plate is set and the copper plate 2 is retracted directly below the transfer pad 1. A table 3 for moving between the positions and a transport mechanism 5 for feeding the tray 4 as the transferred material to directly below the transfer pad 1 are provided, and they are integrally assembled to the base frame 6. Here, the transfer position means a position where the pattern of the copper plate 2 is copied onto the transfer pad 1 and a position where the pattern copied onto the transfer pad 1 is printed on the plate 4, and in the apparatus of the embodiment, any position is the transfer pad 1. Falls under.

The transfer pad 1 is arranged above a transfer position on a horizontal beam 6a of a base frame 6 which is an intermediate part of a printing apparatus including a set of two units, with a protrusion direction of a piston rod 7a directed downward. The mechanism 7 is fixed, and a pair of left and right transfer pads 1.1 is attached to the tip of the piston rod 7a via a horizontal rod so as to be arranged right above each transfer position. 1 is made of elastic silicone rubber.

The tables 3 are connected to each other by being connected to each other as a set of two printing devices, and guide rods 8.8 provided on both sides of the printing device below the transfer pad 1.1. A cylinder mechanism 10 which is movably attached to the upper part of the space along the guide rod 8.8 through sliding members 9.9 ... Attached to the four corners, and which is arranged at the boundary between printing devices. The tip of the piston rod 10a is connected to a bracket 3a protruding below the table 3.3.

Below the table, the transport mechanism 5 passes from one end of the base frame to the other end, and from the other end to the endless conveyor 11 which passes through the base frame and returns to the one end. The pedestals 12.12 ··· on which the plate 4, which is the material, is stably placed are attached with a space between each transfer position of the printing machine, and the direction changing section exposed outside the base frame is used for loading and unloading the plate. The position is set to. The motors 13 are intermittently driven so that each of the pedestals 12.12 ... Stops at the transfer position when passing through the transfer position between the carry-in position and the carry-out position.

Next, the printing plate position adjusting mechanism will be described. A frame body 14 is fixed to the upper surface of the table 3 along the four circumferences thereof, and an ink tray 15 is arranged on the frame body 14. A set position for fixing the copper plate 2 having a pattern engraved at a position slightly deviated from the center is set in the ink tray 15, and the set surface is provided with an encoder 16 and a doctor blade 17 from above. Are in contact with each other, and the table 3 moves to cause the encoder 16 and the doctor blade 17 to relatively slide in the ink tray 15 to scrape the ink in the ink tray 15 to one edge. As a result, the ink is evenly applied to the set copper plate 2. A moving block 18 is fixed to the lower surface of the ink tray 15 in a space surrounded by the frame 14 and has a size that allows a slight movement in the front, rear, left and right directions. It is possible to shift by a predetermined distance.

To make the description easy to understand, when the vertical direction in FIG. 4 is the X axis and the horizontal direction is the Y axis, the X axis is on the center outer surface of one side orthogonal to the X axis of the frame body 14. A direction movement adjusting knob 19 is rotatably provided, and the tip end of the rotating shaft 19a of the X-axis direction movement adjusting knob 19 protruding into the frame has a pressing member 20 whose tip is in contact with the side surface of the moving block 18. However, the X-axis direction movement adjusting knob 19 is screwed so as to be screw-feedable by the turning operation. A concave portion 21 is formed in the moving block 18 on the side opposite to the abutting portion of the pressing member 20, and a cylindrical holder 22 fixed to the frame is fitted in the concave portion 21. A coil spring 23, which is an urging member that pushes back against the pressing direction of the pressing member 20, is housed in the unit 22. Next to the X-axis direction movement adjusting knob 19, two Y-axis direction movement adjusting knobs 24.25 are respectively rotatably provided, and one side of the moving block 18 on a side orthogonal to the Y-axis is separated. Pressing members 26.27 whose front ends are in contact with the inner side surface of the frame body 14 are provided at the two positions through the remote control wires 28.28 by the turning operation of the Y-axis direction movement adjusting knob 24.25. Shaft 24a. It is screwed to 25a so that it can be screwed. Further, a coil spring 29. 30 are provided.

A depression 30.30 is formed at an important point on the upper surface of the moving block 18, and a solenoid valve 31 has a protruding rod 31a at the bottom of each thin plate-shaped bottom of the depression 30.30. The surface and the through holes 32.33 formed in the table 3 are pierced so that they are attached to the lower side of the table, and the pressing pad 34 is fixed to the tip of the protruding rod 31a. Then, a clamping mechanism for locking the moving block 18 by sandwiching the table 3 and the moving block 18 by pulling the pressing pad 34 is provided. In this clamp mechanism, the through hole 33 formed in the table 3 is large so as to allow the movement of the moving block 18 at the time of adjustment, and the pressing pad 34 is wider than the through hole 33. Have an area.

The thus-formed printing machine for painting ceramics puts one plate on the pedestal on the endless conveyor at the carry-in position, and two successive sheets form one set, one after another. It is sent to the copy position. At the transfer position, the table is first moved from the retracted position to the transfer position before the plate is sent, whereby the ink in the ink receiving plate is applied to the copper plate surface. Next, the transfer pad descends and comes into close contact with the copper plate surface, and the pattern of the copper plate is transferred to the pad. The transfer pad rises as it is and stands by, and the table also moves to the retracted position. If the plate is sent to the plate and stops there, or if it is already waiting, the transfer pad descends and prints the imprinted pattern on the plate. Each time a set of two plates is sent to each transfer position, different color printing is repeated and a three-color pattern is added.

When the copper plate is set on the ink tray, for example, in order to match the print pattern, the X-axis direction movement adjusting knob 19 is rotated to extend the pressing member, and the movement block 18 is biased by the coil spring 23. It moves in the opposite direction, and when the pressing member is pulled back, it moves in the opposite direction by the bias of the coil spring 23. Further, by rotating the two Y-axis direction movement adjusting knobs 24.25, it is possible to move in the Y-axis direction in the same manner as the X-axis, and by varying the feeding amount of each pressing member 26.27. It is also possible to change the angle so that the position of the ink tray 15 can be adjusted without moving the operating position.

In the above-mentioned embodiment, the transfer to two sets of plates at the same time is explained, and the three-color sliding is also possible. However, the device for single-color sliding for each one and the multi-color automatic loading and unloading are described. It can also be implemented in a sliding device. Also, a printing machine for painting ceramics in which the ink tray is provided on the table by using both the slider mechanism and the rotating mechanism can be implemented by using the remote operation means. In the present invention, the expressions of the X-axis and the Y-axis are merely used for convenience, and it is understood that, for example, when they are reversed, that is, when they are rotated by 90 degrees, they have the same structure. The left-right position of the side orthogonal to the Y-axis is the left-right position in the X-axis direction, and two pressing members for pressing in the Y-axis direction are not provided on the same side and May be replaced with the biasing member at the facing position.

[0016]

[Effect of the device]

 According to the present invention, since the operating portion of the positioning means for moving and rotating the printing plate in the X-axis and Y-axis directions is centrally arranged in one place of the table, when performing the positioning work of the printing plate, It is possible to operate at the printing position and there is no need to change the operating position, so work efficiency is good. Further, when the ink tray is structured to be moved from the side by the pressing force of the pressing member, there is an advantage that the structure is simple and the space occupied can be reduced.
