Description

Engraving machine

The invention relates to the field of engraving of a flat or slightly convex surface of relatively small products, mainly when performing artistic or decorative work.

Known engraving machine for small flat products (US patent N ° 3570129, 1971), containing mobile vertical and horizontal work tables, on the first of which is attached an engraving head with a diamond tip, and on the second - a workpiece for engraving. A disadvantage of the device is the possibility of its operation only in manual mode and engraving only according to the copied template, exceeding the size of the workpiece.

An engraving machine for products with a non-planar surface is also known (US patent N ° 3830136, 1974). And in this case, the engraving is performed manually with the transfer of the image from a flat template using a structurally complex system of pantographs.

Known engraving installation (RF patent N ° 2309648, 2007), containing a two-coordinate scanning device, means for mounting and moving the processed object, a laser tool for surface treatment and a control device, in the form of a personal computer containing connected to the microcontroller monitor and keyboard. The installation is intended for surface treatment of large-sized objects, mainly stone slabs, and is characterized by a complex design and sophisticated electronic equipment.

The present invention is an engraving machine for engraving on small products, for example, medallions.

The engraving machine according to the invention includes a housing, a base, vertical racks and transverse walls, horizontal and vertical work tables, a workpiece store, a workpiece feed device, a packaging shop, a magnetic shock head, work table feed mechanisms, a workpiece holding device during the cycle engraving, a device for dispensing the finished product and packaging at the end of the operating cycle, positioning and control sensors and an electronic control unit. The horizontal work table rests on the transverse walls, and the vertical work table rests on the vertical posts.

The housing is made in the form of a casing protecting the actuators from environmental influences. Has openings for output signal and control wires, indicators, installation of shops. The base is a supporting structure on which other elements of the machine are mounted. In particular, it can be made of two aluminum squares. Vertical posts are attached to the base and together with the base and transverse walls form the power frame of the machine. :

The device for feeding blanks is made in the form of a pusher, the pushing part of which is made in the form complementary to the blank used, for example, for molded rectangular plates - a U-shaped pusher.

The workpiece holding device is designed to eliminate vibrations and displace the workpiece during the work cycle. For metal workpieces, it can be an electromagnet.

The desktop is a plate with mounting holes. In total, the engraver has two workbenches providing movement of the workpiece (for example, a medallion) along the X axis and moving the tool (magnetic shock head) along the Y axis. In addition, the X axis table allows you to push the package for engraved products from the packaging stores, and the Y-axis table provides automatic feeding of the medallion blanks, pushing them with a U-shaped pusher from the blank magazines.

The feed mechanisms of the working tables provide the translational movement of the working tables. In a preferred embodiment, such mechanisms are made on the basis of screw-nut gears and cylindrical guides. Ballscrews, gears, linear electric drives and other type of guides (for example, rail guides) can also be used.

The magnetic shock head is a solenoid with a core, an engraving needle and a return spring. The movement of the needle is provided by supplying voltage to the coil of the solenoid, and return by a return spring or an electromagnet. The strength of the shock is regulated by the current value or by the time of supply of current in the solenoid winding.

The device for dispensing the finished product and packaging at the end of the working cycle is designed to issue an engraved product and packaging for it at the end of the working cycle. It can be implemented in the form of pushers driven by desktops, or in the form of separate mechanisms.

There can be several stores for packaging with the possibility of placing stores both on one side of the machine, and on both sides of the engraving machine.

The positioning and control sensors are designed to determine the position of the working bodies of the machine, the fullness of the blanks and packaging material stores, and the proper installation of these stores. Mostly they represent battle optical infrared pairs. Induction or capacitive sensors can also be used.

The electronic control unit is a specialized controller that provides the interface of the computer with the actuators and sensors of the machine. The computer can be installed under the casing of the engraving machine or run as a separate unit connected to the controller with connecting cables.

The invention is illustrated by drawings.

In FIG. 1 schematically shows an engraving machine, front view without a front wall of the housing.

In FIG. 2 - engraving machine, top view.

The remaining drawings show the individual components and parts of the engraving machine: magazine for packaging (Fig. 3); a store for blanks (Fig. 4); horizontal working table (Fig. 5) and magnetic shock head (Fig. 6).

In the drawings, the nodes and parts of the engraving machine are indicated by the following serial numbers of positions:

1 - case;

2 - base;

3 - a vertical rack;

4 - transverse wall;

5 - horizontal desktop;

6 - vertical desktop;

7 - store for blanks;

8 - workpiece feeding device;

9 - a store for packaging;

10 - magnetic shock head;

1 1 - the feed mechanism of the horizontal desktop;

12 - vertical feed table feed mechanism;

13 - device for holding the workpiece;

14 - device dispensing the finished product;

15 - positioning and control sensor;

16 - electronic control unit;

17 - device dispensing packaging;

18 - coil of the solenoid;

19 - an engraving needle; 20 - core;

21 - a return spring.

The engraving machine operates as follows. In the store 7 for blanks are loaded blanks, which can be, in particular, medallions or molded plates, both with flat and slightly curved surfaces. Packages (for example, boxes) are loaded into a store or packaging stores 9. From the store 7, one workpiece is moved to the horizontal work table 5 by means of the workpiece feeder 8 attached to the vertical work table 6 and is fixed at a relative position to the work table 5 by the workpiece holding device 13. Together with the working table 5, the workpiece is moved to the working area of the magnetic shock head 10. The exact relative position of the workpiece and the magnetic shock head 10 at each moment of time is set and changed under the control of positioning and monitoring sensors 15. The movement of the work tables 5 and 6 is provided by the mechanisms 1 1 and 12 for feeding the work tables. The set accuracy of movement is determined by the feed pitch.

The electronic control unit 16 contains an electronic copy of the image for engraving. According to the control signals from the electronic control unit 16, engraving occurs (applying the image to the workpiece). In this case, the magnetic shock head 10 is a solenoid with a coil 18, a core 20, an engraving needle 19 and a return spring 21. The needle is fed and returned to its original position by applying electric current pulses to the coil 18, causing the needle to shift, and then the needle is returned to its initial position by the return spring 21. The needle can be returned instead of the spring by other means, for example, using an electromagnet (not shown in the drawings). After the engraving cycle is completed, the finished product is dispensed by feeding the working table 5 under the finished product dispensing device 14. Next, delivery of the packaging from the packaging stores is ensured by feeding the desktop 5 in the direction of the packaging store, determined by the logic of the electronic control unit 16 and further delivery of the product packaging via the packaging delivery device 17.

The engraving machine can be used both for individual work of masters and for general access of any users, for example, in addition to automatic photo booths.
