Description

[Detailed description of the invention] The present invention relates to a stamping rubber support device in a stamping device that stamps grade, class, place of origin, etc. on the side surface of a cardboard box.
The purpose is to perform simple sealing.

In general, there are rotary type and reciprocating type stamping devices for attaching product symbols to the side of packaging containers such as cardboard boxes.
In any case, it is necessary to attach a stamping mat made of rubber or the like on which a stamping symbol is provided to each surface of the rotary stamping dome or the movable arm, making this apparatus complicated.

For example, it is necessary to first fix the stamping mat to a frame or a board, and then attach it to a support using screws or the like.

Since it is not easy to handle and has a complicated configuration, the overall size of the stamping device has to be increased.

The present invention improves the above-mentioned drawbacks, and its configuration will be described below with reference to the drawings of the embodiments.

Reference numeral 1 denotes a rectangular stamping mat made of porous rubber and serving as an ink-impregnated mat having a stamping symbol 2 protruding from its surface.

Reference numeral 3 denotes a metal drum-shaped support, and a receiving groove 5 in which a dovetail groove 4 having an entrance width 1' slightly narrower than the width 1 of the stamping mat 1 and a wider interior is formed on the peripheral surface 3a of the support 3. It is perforated in a band shape in the circumferential direction.

Now, when fitting the porous rubber stamping mat 1 impregnated with this ink into the receiving groove 5 of the rotary metal drum-shaped support 3, first bend the abdomen 1a of the stamping mat 1, and then bend the upper and lower edges 1b. is inserted and guided into the dovetail end 4a of the receiving groove 5, and in this state, if the stamping mat 1 is uncurved, the receiving groove 5 is expanded by the elastic elasticity of the rubber of the stamping mat 1 itself. This stamp mat 1 fits inside.
Since the width 1 is wider than the entrance width 1' of the receiving groove 5,
The edges of the bearing 50 are in a pressed state, and the whole is strongly fitted into a dovetail groove.

In this case, the width 1 of the stamping mat 1 made of porous rubber is 25
rIrIn1 thickness 711FM, entrance width 1' of receiving groove 5 is 24wIt1 groove angle 50, groove depth 5.57rr! It is n.

Further, the receiving groove 5 is formed in the circumferential direction (rotation direction) of the drum-shaped support 3.
Since it is formed over the entire circumference, simply fitting the marking mat 1 into the receiving groove 5 may cause it to rub during rotation.

Therefore, a locking magnet piece 6 that can be fitted into the receiving groove 5 is fitted into the front and rear parts of the stamping mat 1, and this metal support 3
The marking mat 1 is fixed by magnetic adsorption to the 5 sides of the receiving groove.
Prevents sliding from side to side.

Of course, the shape of the magnet piece 6 in this case is curved with an arc corresponding to the drum arc of the receiving groove 5 portion.

Here, the drum type support 3 is rotated by appropriate means to stamp the side wall surface of the box A that has been conveyed on a conveyor B installed on the side thereof.

That is, the stamp symbol 2 of the stamp mat 1 fitted into the receiving groove 5 comes into contact with the wall surface of the box A, which is the object to be stamped, and is automatically stamped.

As mentioned above, the stamp support device of the present invention has a stamp mat fitted into the predetermined position of the A-IJR type receiving groove around the entire circumference of the metal drum-shaped support, and the front and rear positions of the stamp mat ( By adopting a structure in which a magnetic piece to prevent sliding is fixed by suction in the direction of the groove, printing can be performed reliably without causing the printing mat to rub during rotation (printing width).

Moreover, the marking mat and magnet piece can be easily set by simply fitting them into the receiving groove, and since the receiving groove is arranged around the entire circumference of the drum-shaped support, the size of the container such as cardboard to be fed can be easily adjusted. Also, fine adjustment of the positioning according to the arrangement of the printing frame can be easily made.

Since this fitting is held by external fitting, the stamping support can be a rotary type drum-type support as in the embodiment, or a flat plate type such as a reciprocating type or a transporting type. It is also easy to install.

Furthermore, if this marking mat is made of porous rubber that is impregnated with ink, it will not only fit better into the receiving groove, but also the roller can be omitted if the mat is equipped with ink. This has practical effects such as making the device simpler and more compact.
