Description

[Detailed description of the invention] The present invention relates to a hose cutting machine.

Vacuum hoses and the like used in engine exhaust gas purification devices and the like are classified by length and type, and are housed in predetermined storage boxes whose contents are displayed.

By the way, the hose accommodated in the storage box is
The operator selects a specified hose from among the many types of hoses by looking at the information displayed on the storage box, sets the specified hose on a cutting machine, cuts it to a specified length, and then cuts the specified hose to a specified length. The hose cut to length was stored in the predetermined storage box.

Therefore, since the above work is performed at the discretion of the operator, mistakes may occur in selecting the type of hose, setting the cutting length, and storing the specified hose in the specified storage box. There was a risk that the designated hose would not be stored in the storage box.

The present invention solves the above-mentioned problems, and its purpose is to reliably accommodate a predetermined hose in a predetermined storage box.

In order to achieve such an object, the present invention includes a pair of rollers that are disposed opposite to each other and that feed the hose in one direction, and a pair of rollers that are linked to at least one of the pair of rollers, so that the roller is connected to the hose. a rotational drive source that rotates in the feeding direction of the hose, and a cutting means that is disposed closer to the hose feeding direction than the pair of rollers and that appears in and out of the hose feeding path at predetermined time intervals to cut the hose; a storage box whose opening faces the hose feed path and which is closer to the hose feed direction than the cutting means; and a storage box with the opening of the storage box facing the hose feed path. The apparatus is configured to include a detection means for detecting a component of the rotary drive source, and a control means connected to the detection means and controlling the rotational speed of the rotational drive source in response to a detection signal from the detection means.

With this configuration, when a predetermined storage box is placed at a predetermined position, the detection means detects the components of the storage box, and the control means receives the detection signal and adjusts the rotational speed of the pair of rollers. A cutting means that feeds out the hose at a predetermined feeding speed and appears in and out of the hose feeding path at predetermined time intervals cuts the hose to a predetermined length according to the feeding speed. Predetermined hoses can be accommodated in the box.

In order to further clarify the present invention, one embodiment thereof will be described below based on the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a support stand placed on a base 2, and a support member 3 is fixed to one end side of the support stand 1. As shown in FIGS. This support member 3 includes
A hose reel 4 is detachably and rotatably supported, and a predetermined hose 5 is wound around the hose reel 4. A support member (not shown) is fixed to the other end of the support base 1, and shafts 6 and 7 are each rotatably supported by this support member. A roller 8 is fixed to the shaft 6, and a roller 9 and a pulley 10, which face the roller 8, are fixed to the shaft 7. The distance formed by these rollers 8 and 9 is approximately the outer diameter of the hose 5, and the hose 5 is fed out by rotation of both rollers 8 and 9 in the direction in which the hose 5 is fed out from the hose reel 4. be done. These rollers 8, 9 are relatively displaced by displacing at least one of the shafts 6, 7 in the vertical direction, and the rollers 8, 9 are formed to correspond to hoses 5 having different outer diameters. It is now possible to adjust the spacing.

On the base 2, a DC motor 11 as a rotational drive source is arranged within the support 1, and a pulley 13 is attached to the output shaft 12 of the DC motor 11. This pulley 13 is located below the pulley 10, and between the pulleys 10 and 13 there is a support base 1.
A belt 14 passing through the top surface is wrapped around it.

A guide member 15 is disposed on the support base 1 on the side in the feeding direction of the hose 5 relative to the rollers 8 and 9. This guide member 15 includes the rollers 8 and 9.
A through hole 16 that guides the hose 5 sent out by
A slit 17 is formed in a range extending beyond the through hole 16 from one end side to the other end at right angles to the through hole 16. The width is such that the disc 18b can rotate therethrough.

A cutting mechanism 18 as a cutting means is installed on the support stand 1 on the side in the feed direction of the hose 5 (on the right side in FIG. 2) with respect to the rollers 8 and 9, and the cutting mechanism 18 is connected to a motor 18a. , cutter mounting disc 18
b, and a cutter 18c. The motor 18a is fixed to the support stand 1 via a base 18d, and a cutter attachment disc 18b is attached to the output shaft of the motor 18a. The cutter 18 is attached to the outer peripheral edge of the cutter attachment disk 18b.
c is attached, and this cutter 18c passes through the slit of the guide member 15 to the guide member 1.
It faces the through hole 16 of No. 5 at right angles.

The support base 1 has a through hole 16 of the guide member 15.
A housing box receiver 19 is supported, which is located in the discharge area of the cut hose 5 from the housing, and a housing box 20 is disposed in the housing box receiver 19. A plurality of types of the storage box 20 are prepared by changing the length l of one of its constituent elements.

A variable resistor 21 as a detection means having an interlocking relationship with the storage box receiving portion 19 is attached to the lower surface of the storage box receiving portion 19. 19, the resistance value changes from Ro to Rx in accordance with the length l, as shown in FIG.

A control mechanism 22 as a control means is connected to the variable resistor 21, and the control mechanism 22 includes the following:
A DC motor 11 is connected. This control mechanism 22 changes the output voltage of the DC motor 11 from Vo to Vx according to the resistance value Rx of the variable resistor 21, and changes the rotation speed of the DC motor 11. still,
FIG. 3 conceptually shows a state in which the initial output voltage Vo is changed to become the output voltage Vx.

Next, the effect will be explained.

First, when a predetermined storage box 20 is placed on the storage box holder 19 and the hose cutting machine is turned on, the variable resistor 21 changes the resistance value according to the length l as a component of the storage box 20. changes from Ro to Rx. In response to this, the control mechanism 22 determines the output voltage Vx to the DC motor 11 and controls the rotation speed of the DC motor 11. The rotation of the DC motor 11 is transmitted to the shaft 7 by pulleys 10 and 13 and a belt 14. Therefore, correspondingly, the roller 9
is rotated, and the rollers 8 and 9 sandwich the hose 5 between them and send it out to the through hole 16 of the guide member 15. During this time, the motor 18a turns on the hose cutter and at the same time operates the first motor at a constant rotational speed.
In the figure, it is rotated counterclockwise, and -ra 8, 9
The hose 5 sent out is cut into a predetermined length by the cutter 18c. The cut hoses 5 are sequentially discharged outward from the through holes 16, and the cut hoses 5 are stored in the storage box 20.

Storage box 20 having a length l different from the above case
When placed on the storage box receiving part 19, similarly,
The variable resistor 21 has a resistance value according to the length l,
Output voltage to the D motor 11 via the control mechanism 22
Vx is determined, and the DC motor 11 outputs its output voltage
The rotation speed corresponds to Vx. Therefore, the length of the hose 5 to be cut is determined by the speed at which the hose 5 is fed by the rollers 8 and 9.

Although one embodiment has been described above, the present invention includes the following.

The storage box receiving section 19 may have a transport function capable of transporting the storage box 20.

The constituent elements of the storage box 20 are not limited to the length thereof, and may be attached to the storage box 20 in addition to, for example, the weight, shape, etc.

A limit switch, a light sensor, etc. may be used as the detection means. In particular, as shown in FIG. 4, when using the optical sensor 23, the storage box 2
It is preferable to attach the detected member 24 to 0 because the sensitivity increases. Note that 25 is a digital display section. In addition, it is also possible to determine the storage box 20 using a bar code or magnetic tape.

In order to check whether the type of hose 5 to be cut matches the display contents of the storage box 20,
0 component may be detected and its display contents may be displayed on the operation panel (see FIG. 4).

As is clear from the above description, the present invention allows the hoses to be stored in the storage box to be continuously cut and stored by simply positioning the storage box at a predetermined position. The specified hose is securely stored in the storage box.
Therefore, during the hose installation work, by determining the predetermined storage box, the predetermined hose can be taken out without fail.
