Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material positioning device for a marking machine for marking tube materials.

In tube material marking machines that mark various letters, numbers, etc. on marking tubes that are placed over electric wires, etc., the tube material to be marked tends to roll on the pedestal, so that the markings tend to be unclear. For this reason, the worker usually has to grasp both sides of the marking portion of the tube material, resulting in a disadvantage that the workability is extremely low.

An object of the present invention is to provide a material positioning device for a tube material marking machine that can stably hold the tube material to be marked at the marking position.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a material positioning device 10 of a tube material marking machine according to the present invention,
This device comprises a pedestal 14 mounted on a machine pedestal 12, and the tube material 1 to be marked is fed from the side onto the pedestal 14 at fixed pitches for each marking operation by a material fixed pitch feeding means 16. be provided. The material constant pitch feeding means 16 has a tube through hole 18.
a case 18 and a tube material 1 disposed within the case and passing through the tube through hole 18a.
The tube material 1 is made up of a pressure roller and a feed roller (not shown) that sandwich the tube material 1, and the feed roller rotates at a fixed angle every time the marking operation is completed to transfer the tube material 1 to the pedestal 14.
sequentially. In addition, in FIGS. 1 and 2, the reference numeral 20 is a tube material feeding knob.

A pair of guide plates 24, 2 are provided on both sides of the pedestal 14.
4' are arranged, and these guide plates 24, 24' are driven by drive means 26.

As shown in FIG. 4, the pair of guide plates 24, 24' have a plurality of material through holes 24a, 24'a facing each other at regular intervals in the circumferential direction. The holes 24a, 24'a have the same diameter, but adjacent through-material holes 24a or 24'a have different diameters to accommodate the different outside diameters of the tube material. Therefore, the material through hole 1 of the material constant pitch feeding means 16
Through-holes 2 of various diameters to match 8a
By sequentially displacing and positioning the tubes 4a and 24'a, it is possible to position tube materials of various outside diameters that are sequentially fed from the side by the material fixed pitch feeding means 16.

The driving means 26, as shown in FIG.
A drive shaft 30 passes through the through hole 14a of No. 4, is rotatably supported by a spacer 28, and passes through the guide plates 24, 24'.A nut 32 is attached to the threaded end of the drive shaft 30 on the guide plate 24' side. are screwed together,
A stop plate 34 and a knob 36 are screwed onto the threaded end of the drive shaft 30 on the guide plate 24 side. Therefore,
When this knob 36 is turned, a pair of guide plates 24,
24' simultaneously rotate in the same direction. A spring snap mechanism 44 is provided between the pedestal 14 and the guide plate 24' and is comprised of balls 42 that are fitted into a plurality of ball receivers 40 provided on the inner surface of the guide plate 24' by a snap spring 38. . The guide plates 24, 24' therefore have one material through hole 24 in each case.
a, 24'a are positioned by the spring snap mechanism 44 each time they coincide with the material through hole (feeding passage) 18a.

In addition, in FIG. 1, the reference numeral 46 indicates a colored tape 48.
When a handle (not shown) is pressed down, the type wheel 46 marks the tube material to be marked on the pedestal 14 via the colored tape 46.

According to the present invention, as described above, the tube material to be marked on the pedestal is provided on both sides of the pedestal, and the guide plate in which the material through hole of a predetermined diameter is positioned in line with the feeding path of the tube material. Since the tube material is reliably positioned together with the cradle by these guide plates, the tube material will not shift during marking, and the guide plates have material through-holes of various diameters, so that they can be used with various outside diameters. markings can be applied to the tube.

Claims (1)

[Scope of utility model registration request] A material positioning device for a tube material marking machine, which comprises a pedestal, through which the tube material to be marked by the lowering of a type wheel is fed sequentially from the side at a fixed pitch for each marking operation, arranged on both sides of the pedestal. It consists of a pair of guide plates and a driving means that rotatably penetrates the pedestal and rotates the pair of guide plates, and the pair of guide plates feed the tube material at regular intervals in the circumferential direction. The driving means has a plurality of opposing material through-holes having different diameters corresponding to various outer diameters of the tube material so as to correspond to the passage, and the driving means has each material through-hole coincident with the feeding passage of the tube material. A material positioning device for a tube material marking machine, comprising a snap mechanism for positioning the pair of guide plates at a position.
