Description

[Detailed description of the invention] This invention is a device that automatically stamps the product name, quality, etc. of the contents on the side of cardboard boxes, etc. that are transported by a conveyor, using an ordinary rubber stamp and a stamp pad. It is related to.

Conventionally, to automatically stamp the sides of cardboard boxes, etc. on a conveyor, a rubber stamp made of open-celled sponge rubber impregnated with ink has been used, or an impregnated ink roller has been brought into contact with the outer periphery of a rotating rubber stamp. However, since all of these marking devices are impregnated with highly viscous ink, the ink adheres well at the beginning of use, but as the number of stamps increases, the ink gradually decreases. This has the disadvantage that a clear stamp cannot be obtained, and it is necessary to refill the ink several times, but since the viscosity of the ink is high, it is necessary to refill or inject the ink with a sponge rubber stamp or an ink roller. It is difficult to do this, and there is a drawback that it is not possible to automatically stamp continuously for a long period of time.

In order to eliminate these drawbacks, this invention uses ordinary rubber stamps and
A table-top stamp stand is used so that the rubber stamp comes into contact with the stamp stand each time a stamp is stamped.The rubber stamp usually waits with its stamp surface touching the top of the stamp stand, and when a cardboard box is transported, an electrical command is sent to the rubber stamp. The actuating device moves the rubber stamp away from the stamp pad, turns horizontally, stamps the side of the cardboard box, and then returns to its original top surface of the stamp pad, allowing continuous automatic stamping for a long period of time. It is.

Ink replenishment is also simplified by simply supplying ordinary stamp ink to the top of the stamp stand.

However, the gist of the present invention is to connect one end of a column to which a print holder with a print such as a rubber stamp removably attached to one end in a telescopic manner, and one end of an operating arm that operates the print holder using each fulcrum pin. A guide pin supported by the frame and implanted in the print holder is passed through a guide groove diagonally drilled in the device frame and engaged with a long hole provided at the other end of the actuating arm. The stamping device is characterized in that one end on the stamping side extends horizontally and the other end on the stamp stand side extends vertically, and a printing holder is moved along a guide groove by rotation of an operating arm.

The embodiments of the present invention shown in the drawings will be explained below.1
is the main body frame of the stamping device, and is installed on the upper side frame 3 of the conveyor for carrying the cardboard box 2 so as to match the height of the stamping part of the cardboard box 2.

Reference numeral 4 denotes a stamp stand moistened with ink, which is fixed at a predetermined position, for example, at a rest or standby position of the rubber stamp.

Reference numeral 5 is a rubber stamp which is easily attached to and removed from the print holder 6, and during normal standby (when no printing operation is being performed) it is in contact with the upper surface of the stamp stand 4 with the stamp surface facing downward.

The print holder 6 has a sliding socket part 6a on the back (on the side opposite to the rubber stamp), into which a print support 7 is fitted, and the print support 7 is attached by a support pin 8 on the print side so that it can freely swing from vertical to horizontal. , and slidably guides the print holder 6 in an axially expandable and retractable manner.

A guide pin 9 is installed on the side of the print holder 6, and is fitted into a guide groove 10 provided in the main body frame 1 to regulate the movement of the print holder 6 and therefore the rubber stamp 5.

The guide groove 10 is formed by a rubber stamp 5, as shown by the thick line 10a in FIG.
At the lower end A-B where it contacts the stamp pad 4, it moves vertically up and down, and at the upper end CD where the stamp is stamped on the side surface 2a of the cardboard, it moves horizontally and linearly for stamping.

11 is an operating arm that operates the print holder 6;
It is attached to the guide groove 10 so that it can freely swing from horizontal to vertical by means of an operating side fulcrum pin 12 provided at a position symmetrical to the printing side fulcrum pin 8, and the guide pin 9 of the printing holder 6 is loosely fitted to the tip. It has a long hole 13 and is connected to an actuating device 14 (the illustrated example is an air cylinder).

To explain in more detail using FIG. 5, the print holder 6
The column and the actuating arm 11 are provided at diagonally symmetrical positions E and F, the print holder 6 slides and expands and contracts in the range of V-W, and the actuating arm 11 penetrates into the elongated hole 13 in the range of X-Y. Guide pin 9 can be guided.

The actuating device 14 causes the actuating arm 11 to engage the guide pin 9.
The range in which the print holder 6 is guided is between XR and YR, and the range in which the print holder 6 slides and expands and contracts is between VR and WR.

The guide range where both overlap is the part surrounded by E-L-H-A-N-H-H-H-T. In this range, the print holder 6 can be guided in any way by the implanted guide pin 9, but in order to operate effectively, As shown by the thick line,
A guide groove 10 is provided to allow a guide pin 9 to pass through the guide groove 10 to regulate the movement of printing.

The feature of this stamping device is that when the surface of the rubber stamp 5 is stamped on the side surface 2a of the cardboard box and when it comes into contact with the top surface of the stamp pad 4, it is structured so that it makes surface contact at right angles to each surface, so there is no misalignment of the printing. The stamp pad 4 and the rubber stamp 5 should not be damaged.

Another feature is that the actuating arm 11 acts at a right angle at the positions A and D where the print holder 6 starts moving, so that the print holder 6 can be extended and contracted and operated very smoothly.

Yet another feature is that the rubber stamp 5 is not special;
An ordinary rubber stamp can be used, and the stamp pad 4 is a regular desk stamp pad, so it is inexpensive and economical, and it does not run out of ink for a long time, making clear stamps, and it is easy to refill the ink. It is similar to a stamp pad used on a normal desk and is easy to handle.

Reference numeral 15 denotes a flap holder for the cardboard box 2, which presses the side top lid 2b when the top lid of the cardboard box 2 to be stamped is not yet folded and remains open (standing vertically) (FIG. 6). When stamping on a product, it works to support the stamped surface from the inside so that it does not escape due to pressure during the stamping process.

The flap holder 15 is axially mounted on the main body frame 1 by a fulcrum pin 16, and is linked with the printing operation of the print holder 6 by an arm 18 extending in an L shape from the print support 7 into a long hole 17 extending on the symmetrical side and a floating pin 19. There is something that works.

If a stamp is to be placed on the side surface of the cardboard box (FIG. 7) after the cardboard box has been opposed, the mechanism of the flap presser 15 is not necessary.

Although the actuating device 14 is an air cylinder in the embodiment shown, other devices (for example, a rotary solenoid) can also be used to swing the actuating arm.
