Description

[Detailed explanation of the idea] The present invention relates to an improvement of a vacuum contact printing machine.

In conventional vacuum contact printing machines, after the lid is brought into close contact with the underframe, a locking operation is required to lock the lid and the underframe in addition to the opening/closing operation of the lid. , Even if it is automatic, a release means is required to release the lock.

In view of the above circumstances, the present invention is characterized in that the lid can be locked and unlocked extremely easily and reliably by simply opening and closing the handle attached to the lid.

Hereinafter, embodiments of the vacuum contact printing machine according to the present invention will be described in detail based on the drawings.
An underframe 2 is provided on the underframe 2, a sheet 4 having an airtight packing 3 surrounding it is stretched over the underframe 2, and a lid body 6 is connected to the pedestal 1 by a connecting device 5 so as to be openable and closable in close contact with the sheet 4. Equipped with
Mounting brackets 7, 7 each having a substantially U-shaped cross section are arranged side by side on the front wall of the lid 6, and a locking body 8 is positioned within the U-shape of the mounting bracket 7, and the outer side of the mounting bracket 7 is A rotary plate 9 is positioned at , and both are rotatably supported by a single pin 10 .

The above-mentioned locking body 8 has a spring 11 attached to its upper part with one end in contact with the back wall of the mounting bracket 7, and a spring 11 that is in contact with the back wall of the mounting bracket 7 at the middle part slightly below the shaft bearing position of the locking body 8. A locking body abutting part 12 is formed to always hold the locking body 8 in a fixed position, and a locking part 13 is provided at the lower end of the locking body 8. A slope 15 a is provided on the upper part of the frame 2.
A rotor 14 that smoothly engages with a locking protrusion 15 is attached.

A pipe-shaped handle 16 is installed between the rotary plates 9, 9.
17. Each rotating plate 9 is provided with a rotating plate abutting portion 18 that contacts the front wall of the lid 6 so that the handle 16 does not move excessively below the pin 10. The movable plate 9 is provided with a release pin 19 that presses the upper part of the locking body 8 by its rotational movement.

In the figure, reference numeral 20 indicates a microswitch, and each of the microswitches 20 and 20 is connected to the rotor 14 of the locking portion 13.
An electrical series circuit is constructed so that switching occurs when the button is pressed.

Further, the lid body 6 is composed of a lid frame 22 to which a glass 21 is attached.

In the vacuum contact baking machine having the above configuration, when the lid body 6 is closed tightly, when the handle 16 is pushed down,
The rotor 14 attached to the locking body 8 is connected to the locking protrusion 15 of the underframe 2.
The locking body 8 rotates around the pin 10, and the spring 11 attached to the top of the locking body 8 is rotated. When the handle 16 is pressed down and the handle 16 is further pushed down, the rotor 1 of the locking body 8
4 moves below the locking protrusion 15, and at this time the locking body 8
The locking body 8 rotates around the pin 10 due to the restoring force of the spring 11 attached to the upper part of the locking protrusion 1, and the rotor 14
5, and the locking body contact portion 12 further contacts the back wall of the mounting bracket 7.

In addition, when opening the lid body 6, first lift the handle 16 upwards, and the rotating plate 9 will move around the pin 10 to hold the handle 16.
This causes the release pin 1 provided on the rotating plate 9 to
9 presses the upper part of the locking body 8, and the locking body 8 rotates, so that the rotor 14 of the locking portion 13 is released from the locking protrusion 15.

Note that the rotating plate contact portion 18 of the rotating plate 9 is in contact with the side wall of the lid 6 in a normal state.

Moreover, when the rotor 14 mentioned above is locked with the locking protrusion 15, switching is performed when the microswitches 20, 20 provided on the underframe 2 are pressed, respectively.

As described above, according to the present invention, the lid can be opened and closed extremely easily by simply moving the handle up and down, and the locking body and rotating plate can be rotated via the mounting bracket on the front side wall of the lid. Since it is movably supported on the shaft and a spring is attached to the upper part of the locking body, the engaging part provided on the locking body and the locking protrusion provided on the underframe can be engaged with each other by the downward movement of the handle ( This can be done extremely easily and reliably by the closing operation of the lid body, and the rotation plate also rotates the locking body by pressing the upper part of the locking body when the lid is opened by the rotating plate. Since a release pin is provided to release the engagement between the locking part of the locking body and the locking protrusion of the underframe, when the handle starts to move upward (opening of the lid), you can simply lift the handle. At the start of operation), the locking part of the locking body and the locking protrusion of the underframe can be unlocked very easily and reliably, and the lid can then be raised, making it easy to open the lid. It has excellent effects such as being able to perform the process quickly and smoothly.
