Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an automatic hot stamping machine for hot stamping materials for, for example, number wheels and character wheels.

[Prior art]

For example, to display numbers on a number wheel used in a counter, etc., a rotary body made of synthetic resin to be stamped having a positioning pin is held between a pair of supports including a support body having a positioning groove, and the circumferential surface of the stamped rotating body is This is done by transferring the display foil using the hot stamping method.

However, when this type of rotary body to be stamped has segment gears protruding from the side edges, positioning the rotary body to be stamped on the support body without damaging the segment gears becomes an extremely complicated task. Therefore, there is a demand for an automatic hot stamping machine that can easily perform the positioning work.

[Summary of the idea]

The present invention was developed in response to these demands, and includes a spring that is loaded in a holding rod that clamps the rotating body to be stamped together with a transfer rod and that gives the receiving rod a return behavior, and a spring that detects the initial position of the receiving rod. To provide an automatic hot stamping machine which can quickly perform a stamping operation and can easily detect whether the condition of the stamp on a rotary body to be stamped is good or bad by having an extremely simple configuration including a detecting means for stamping. Hereinafter, the configuration and the like will be explained in detail with reference to embodiments shown in the drawings.

〔Example〕

1 and 2 are a sectional view and a perspective view showing an automatic hot stamping machine according to the present invention. In these figures, 1 is a transfer rod that moves back and forth in the axial direction, and is attached to a carrier table 3 on which a feeder 2 is attached. A support pin 7 for supporting a stamped rotary body 6 having a segment gear 4 and a positioning pin 5 is connected to the tip thereof. Reference numeral 8 denotes a holding rod having a receiving hole 9 opened at one end, which is positioned coaxially with the transfer rod 1 and rotatably disposed on the receiving stand 10. The holding rod 8 has a fitting groove 11 at the tip thereof into which the segment gear 4 is fitted, and the receiving hole 9 is provided with a through hole 12 that opens laterally. Reference numeral 13 denotes a receiving rod having two diameters, large and small, which has a guide hole 14 into which the supporting pin 7 faces, and is provided so as to be movable forward and backward within the receiving hole 9. Further, a switch actuator 16 with a flange 15 is connected to the circumferential surface of the receiving rod 13 by a connecting pin 17 inserted into the through hole 12. 18 is a spring that imparts a return habit to the receiving rod 13;
It is elastically loaded between the hole bottom 9a in the holding rod 8, that is, the receiving hole 9, and the receiving rod 13. As a result, it is possible to reduce the impact caused by the collision that occurs when the rotary body 6 to be stamped is positioned on the receiving rod 13. Reference numeral 19 denotes a detection means for detecting the initial position of the receiving rod 13, which consists of a light-emitting element 20 and a light-receiving element 21, which are provided on the sides of the switch actuator 16 so as to be aligned with the optical axis of each other. , 21, an output signal is sent out and it is possible to detect that the rotary body 6 to be stamped is properly positioned. 22 is a roller for pressing the display tape, which is disposed on the side of the transfer rod 1 and the holding rod 8 so as to be able to move forward and backward;
It is configured to press the display tape 23 attached to the circumferential surface 6a of the rotary body 6 to be stamped, which is held between the rods 1 and 8. As a result, the display foil 23a peeled off from the display tape 23 is transferred onto the circumferential surface 6a of the rotary body 6 to be stamped. 24 is a positioning groove into which the positioning pin 5 engages;
It opens laterally and is formed at the tip of the receiving rod 13.

Therefore, when the rotary body 6 to be stamped is properly positioned as shown in FIG.
The collar 15 is interposed between both elements 20 and 21, and this shields light between both elements 20 and 21, and an output signal is sent out.

On the other hand, as shown in FIG.
If the positioning of the switch actuator 16 is incorrect, the receiving rod 13 is in a retreated position against the elastic force of the spring 18, so that the flange 15 of the switch actuator 16 is in contact with both elements 2.
It will be located outside between 0 and 21, and both elements 2
The area between 0 and 21 is opened.

In this embodiment, the positioning pin 5 is shown as a protrusion protruding from the side surface of the rotary body 6 to be stamped, but the present invention is not limited to this. Even if a heart cam (not shown) is provided protruding from the side surface opposite to the segment, the same effects as in the embodiment can be obtained. In this case, the positioning groove 24 into which the heart cam engages is the transfer rod 1.
Of course, it is formed at the tip of the.

In addition, in this embodiment, the transfer rod 1 and the holding rod 8
Since the rotary body 6 to be stamped held between them rotates together with the receiving rod 13 and the holding rod 8 during positioning, the transfer rod 1 is rotatably provided on the carrier stand 3 so that the tip of the transfer rod 1 does not wear out. It is desirable that the

[Effect of idea]

As explained above, according to the present invention, there is a spring which is elastically loaded in the holding rod that clamps the rotary body to be stamped together with the transfer rod, and which imparts a return behavior to the receiving rod;
Since it is equipped with a detection means for detecting the initial position of the receiving rod, it is not only possible to easily position the rotary body to be stamped without damaging the segment gear, but also to support the rotary body to be stamped between the transfer rod and the holding rod. In doing so, the forward operation of the transfer rod toward the holding rod side can be performed quickly, and the stamping work time can be shortened. Furthermore, by detecting the initial position of the receiving rod, it is possible to easily detect whether the stamp condition of the rotary body to be stamped is good or bad.
