Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pipe supply device for separating rubber hoses cut into short pieces one by one and supplying them to the next step.

[Prior Art] When assembling, for example, a brake hose that has been cut into a short length, a fitting operation of inserting terminal fittings into both ends of the hose and caulking, and a printing operation of printing a necessary mark on the surface of the hose are performed. . Of these, the metal fitting work is performed using an automatic production line that transports the metal fittings with a vibrator type transfer device, but the printing work is difficult to separate one by one due to the bending of the hose itself and the surface friction force. Therefore, at present, a manual method of manually transporting the hose is used.

[Problems to be solved by the invention] When assembling the brake hose as described above, metal fittings and printing work are required, but since it is intended for mass-produced products (about 300,000 pieces / day or more), An automated production line will become an essential issue. However, in the case of a rubber hose, it is difficult to separate them one by one due to the suction force due to bending and friction as described above, and there is a dislike that automation cannot proceed.

An object of the present invention is to provide a pipe supply device that stably conveys short cut rubber hoses such as brake hoses one by one to the next step.

[Means for Solving the Problems] The present invention provides a tube body supply device for separating tube bodies such as rubber hoses cut into short pieces one by one and supplying them to the next step.
A flat belt that feeds the slope to the next process while accommodating the pipes supplied from the previous process one by one in grooves provided at equal intervals, and a flat belt that is attached to the middle part of the flat belt and overlaps with the above groove. And a round bar that pushes back and adjusts the uneven tubes that are accommodated in it, a round bar receiving part that supports the round bar, and a tube sensing plate that aligns the tubes supplied from the previous process to the flat belt in an appropriate amount. The feature is that the device is configured by, and aims to achieve the objective by continuously and stably supplying rubber hoses and the like to the next step.

[Operation] In the pipe feeding device of the present invention, for example, when conveying short rubber hoses one by one to the next step, flat belts running along the slope are provided with grooves at equal intervals, and the grooves are supplied from the previous step. Store and transport the rubber hoses one by one, and if the rubber hoses overlap and are accommodated in this groove, push back and align the overlapping pipes with the round bar attached to the middle part of the flat belt. Therefore, it is possible to stably and continuously supply the short rubber hose, which has been difficult to automatically feed in the past, to the next step.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory view showing an embodiment of the pipe body supply device of the present invention, and FIGS. 2 and 3 are respectively a case where the pipe body is stably conveyed and a case where the pipe body is superposed (unstable). And FIG. 4 are explanatory diagrams in the case of modifying the overlapping portion.

In each figure, 1 is a flat belt, 2 is grooves formed in the flat belt 1 at equal intervals, 3 is a tubular body such as a rubber hose, and 4 is a tubular body 3.
5 is a round bar receiving portion that supports the round bar 4, 6 is a tube sensing plate that adjusts the tube 3 in an appropriate amount, 7 is a pulley that supports both ends of the flat belt 1, and 8 is A variable speed motor, 9 is a belt, 10 is a pre-process portion for supplying the tubular body 3 to the flat belt 1, and 11 is a connecting plate for the next process.

The pipes 3 cut to a predetermined length (100 to 600 mm in the case of a brake hose) are stacked on the pre-process section 10 and transported, and an appropriate amount drops on the flat belt 1 by interlocking with the pipe detection plate 6. To be done. The flat belt 1 has a width approximately the same as the length of the tube body 3 to be supplied, and the grooves 2 are provided at equal intervals. Groove 2
Is slightly smaller than the diameter of the pipe body 3, and its width is made larger than the pipe body diameter in consideration of the bending of the pipe body 3.

When driving the apparatus, the variable speed motor 8 is started, and the flat belt 1 is caused to travel in the arrow direction via the belt 9 and the pulley 7. At this time, the tubes 3 stocked on the tube sensing plate 6 are housed one by one in the groove 2 (Fig. 2), and then the flat belt 1
As the vehicle travels, it rises along the slope, drops when reaching the connecting plate 11, and is sent to the next step. The inclination angle of the flat belt 1 is set so as to naturally drop the excess pipe body when the pipe body 3 is placed on the groove 2 in an overlapping manner. In the case of pipes having a large surface frictional force, they interfere with each other and attract each other, and as shown in FIGS.
In such a case, the extra pipe body 3b that is forcibly superimposed must be removed.

The round bar 4 and the round bar receiving portion 5 are provided for this purpose and are attached to the intermediate portion of the flat belt 1. Round bar 4
Has a structure in which both ends are supported by the round bar receiving portion 5 and can rotate, and those having different weights can be used.

FIG. 4 shows the case where the tubes 3a and 3b are further raised from the state of FIG. 3 and the tube 3b comes into contact with the round bar 4, and the tube 3b is pushed back by the round bar 4 and its weight Shows the situation in which the flat belt 1 is dropped.

As described above, by using this device, even in the case of a pipe body such as a brake hose that is difficult to separate, it can be stably and continuously supplied to the next step.

In this embodiment, a short rubber hose such as a brake hose has been described, but it is also applicable to other metal round pins, iron or non-ferrous pipes having a circular cross section, or nipples used for brake hose intermediate joint fittings. It is possible to obtain the same effect.

[Effect of the Invention] As described above, according to the present invention, the following effects can be obtained.

(1) It is possible to stably and continuously supply short-cut pipes such as a brake hose to the next step.

(2) It becomes possible to construct an automatic assembly line for short hoses, and the production volume can be dramatically increased.

(3) Product cost can be reduced due to a dramatic increase in production volume.
