Description

  The present invention relates to an automatic supply device for long thin pipes, and more specifically, even when long thin pipes with pipes such as nuts are entangled and stacked on one end, they are separated one by one. The present invention relates to an automatic supply device for long thin pipes.

Conventionally, as an example of this type of long thin pipe automatic supply device, as shown in FIG. 3, a long thin pipe 10 that is fed and accumulated between opposing storage plates 11 of a roll hopper type feeding device. Is sent out while falling in a row between the feed plates 13 by the rotation of the feed turn plate 12 (see FIG. 6 of Patent Document 1), or as shown in FIG. A system that feeds while feeding between feed plates 14 is known (see FIG. 7 of Patent Document 1). The thin long thin pipes 10 fed out by the roll hopper type feeding device or the shooter type feeding device are supplied to the next processing machine one by one automatically or manually.
There is no problem when the pipe is stiff and relatively short, but when it becomes a long thin pipe having a long and flexible shape, for example, in the case of the roll hopper type feeding device described above, it is long when accumulated. The small-diameter pipe 10 gets tangled. This entanglement is not easily removed by the rotation of the feed rotation plate 12, and the long thin pipes 10 placed between the storage plates 11 remain in a tangled state. Cannot be fed between the feed plates 13. This phenomenon is particularly noticeable when nuts are inserted near both ends of the long thin pipe. The same applies to the long thin pipe 10 fed by the shooter type feeding device shown in FIG.
For this reason, in the above-described conventional pipe supply device, the progress of the work of separating a large number of the long thin pipes loaded one by one and supplying them to the next processing machine is stagnant, Auxiliary work was required, and unnecessary man-hours were required.

Solves the above problems and can automatically separate many long thin pipes one by one even if they are entangled, especially long thin pipes with pipes such as nuts at the end As a self-feeding device, a plurality of separation plates are provided substantially concentrically at a predetermined interval, and each separation plate is provided with an engaging portion with a phase shifted in the rotation direction, and one end side is aligned. A large number of long thin pipes arranged in a row are sequentially engaged with a plurality of separation plates one by one by the engaging portion so as to be separated from other long thin pipes. An automatic supply device for a long thin pipe configured in (1) to (5) is proposed (see FIG. 1 to FIG. 5).
This automatic supply device for long thin pipes is a mechanism that can uncouple the pipes from a bundle of many long thin pipes that are intertwined and automatically separate the long thin pipes one by one. The long thin pipe automatic supply device is simple in structure and advantageous in terms of manufacturing cost and operation cost.

However, in the device disclosed in Patent Document 1, when a piping component such as a nut is inserted near the end, it is not smooth to untangle one long thin-diameter pipe. May be caught, causing damage to piping parts such as long thin pipes and nuts, and bending long thin pipes. In addition, the apparatus is complicated and the equipment cost is high.
The present invention has been made to solve the above-mentioned problems, and it is possible to easily unravel the long thin pipe in which piping parts such as nuts are inserted in the vicinity of the end portion. It is an object of the present invention to provide a long thin pipe automatic supply device that does not cause damage to piping parts such as nuts and nuts or bends a long thin pipe.

The long thin pipe automatic supply device according to the present invention is an automatic supply device for long thin pipes having pipes such as nuts at the ends, and is long in the longitudinal direction of a cylindrical surface having a predetermined diameter. A support cylinder having a groove that is wider and slightly deeper than the diameter of the small-diameter pipe is pivotally supported so that it can rotate forward and backward, and a fixed support member and a movable support member are arranged on the surface of the support cylinder in a non-contact manner. The fixed support member is fixed substantially vertically above the support cylinder and vertically along the longitudinal direction of the support cylinder, and the movable support member is supported with the support shaft of the support cylinder being substantially concentric. It is configured to be reciprocally rotatable along the surface of the cylinder, and the long thin pipe supplied between the fixed support member and the movable support member is rotated toward the fixed support member. By collecting it on the upper surface of the support cylinder. In addition, a long thin pipe is accommodated in the groove of the support cylinder, and the long thin pipe is dropped one by one by rotating the support cylinder in this state. To do.
Further, in the device of the present invention, the groove on the surface of the support cylinder has a U-shaped cross section, the fixed support member and the movable support member are formed of a plate-like or fence-like member, The length is shorter than the total length of the long thin pipe to be processed.

The device according to the present invention is a system in which long thin pipes with piping parts such as nuts near the end are securely accommodated one by one in the groove on the surface of the support cylinder and taken out. One by one can be easily separated from a bundle of long thin pipes. In addition, since the number of times that the worker supplies the long thin pipe and the time for checking the inspection can be greatly reduced, the work efficiency can be greatly improved. Furthermore, since the entanglement between the long thin pipes can be easily and reliably unraveled, it is possible to maintain the quality without damaging the long thin pipe or nut or bending the long thin pipe. Moreover, the equipment is simple and the equipment cost is not high.

  FIG. 1 is a schematic perspective view showing an embodiment of an automatic supply device for long thin pipes according to the present invention, FIG. 2 is a diagram for explaining the operation of the above apparatus, 1 is an automatic supply device for long thin pipes, A support cylinder, 2-1 is a support shaft, 3 is a fixed support member, 4 is a movable support member, 4-1 is a support arm, 4-2 is a connecting plate, 5 is a groove, and 6 is a guide hopper.

A long thin pipe automatic supply device 1 according to the present invention shown in FIG. 1 is a long thin pipe having a pipe component 10-1 such as a nut attached to the end in the longitudinal direction of a cylindrical surface having a predetermined diameter. A support cylinder 2 having a groove 5 wider and slightly deeper than the diameter of 10 and having both ends supported by a support shaft 2-1 so as to be able to rotate forward and backward, and a width approximately the same as the length of the support cylinder 2 And having a gap with a gap narrower than the pipe diameter in a non-contact manner with the surface of the support cylinder at a position eccentric from the vertical center line of the support cylinder 2 by the diameter of the long thin pipe 10. A plate-shaped fixed support member 3 fixed substantially vertically along the longitudinal direction, and one end of the support cylinder 2 coaxially with the support shaft 2-1 of the support cylinder 2 is pivotally attached to a rotation shaft 4-3. From the diameter of the pipe in a non-contact manner with the surface of the support cylinder 2 on the other end side of the pair of support arms 4-1 with stoppers 4-4 The movable support member 4 includes a connecting plate 4-2 attached with a gap of a large interval, and is provided so as to be reciprocally rotatable along the surface of the support cylinder 2 with the rotary shaft 4-3 as an axis. It consists of and. The support cylinder 2 and the support arm 4-1 are configured to be rotated or swinged by a drive device (not shown) such as a motor.

  Here, the groove 5 provided on the surface of the support cylinder 2 is preferably formed in a U-shaped cross section, and the width of the groove 5 is slightly wider than the diameter of the long thin pipe 10 to be supplied, and The depth is formed slightly deeper than the diameter of the long thin pipe 10, and the length in the groove 5 when the long thin pipe 10 is almost completely buried in the groove 5 and the support cylinder 2 is rotated. The small-diameter pipe 10 is provided so as not to be caught by the lower end portion of the fixed support member 3.

  Further, the movable range of the movable support member 4 is slightly different depending on the amount (the number) of the long thin pipes 10 to be supplied, but from the inclined position that is lowered slightly from the horizontal to the vicinity of the fixed support member 3. It is a range. The stopper 4-4 is for preventing a number of long thin pipes 10 on the movable support member 4 from dropping.

  The lengths of the support cylinder 2 and the movable support member 4 are preferably shorter than the length excluding the piping component 10-1 such as a nut attached to the end of the long thin pipe 10 to be supplied. If comprised in this way, since the smooth part of the long thin pipe 10 will contact the surface of the support cylinder 2 and the movable support member 4, a long thin pipe will slide smoothly. Further, the fixed support member 3 and the movable support member 4 are plate-like members here, but are not particularly limited as long as they can support the long thin pipe 10 such as a fence shape or a net shape. Absent.

Next, the long thin pipe automatic supply device 1 having the above-described configuration is used to put one long thin pipe 10 having a pipe component 10-1 such as a nut on the end portion entangled and stacked one by one. The operation in the case of separation will be described with reference to FIG.
First, as shown in FIG. 2A, in a state where the movable support member 4 is fully opened to an inclined position that is lowered slightly from the horizontal, a large number of long thin pieces to be supplied onto the movable support member 4 are provided. The diameter pipe 10 is placed. At this time, the long thin pipe 10 is placed on the movable support member 4 at random. However, since the length of the support cylinder 2 is shorter than the length of the long thin pipe 10, the piping component 10- such as a nut is used. 1 is located outside the ends of the support cylinder 2 and the movable support member 4 as shown in FIG. The groove 5 on the surface of the support cylinder 2 may be positioned between the fixed support member 3 and the movable support member 4, but is usually positioned in a range where the long thin pipe 10 does not exist. deep.
Next, as shown in FIG. 2B, the movable support member 4 is turned to the fixed support member 3 side and closed, and the long thin pipe 10 is placed on the upper surface of the support cylinder 2. Subsequently, when the movable support member 4 is opened again, the other long thin pipe 10 is moved on the surface of the support cylinder 2 and the inclined movable pipe, leaving one long thin pipe 10 positioned almost directly above. The surface of the support member 4 rolls down and is stocked on the movable support member again (FIG. 2 (c)). In this state, when the support cylinder 2 is rotated forward so that the groove 5 passes through the lower end of the fixed support member 3 and is positioned on the vertical center line of the support cylinder 2, one long length remaining in the portion. The small-diameter pipe 10 rolls into the groove 5 and is accommodated (FIG. 2 (d)). Thereafter, when the support cylinder 2 is reversed and positioned on the lower side with one long thin pipe accommodated in the groove 5, the long thin pipe 10 in the groove 5 is naturally dropped and discharged. Then, it falls into the guide hopper 6 following the next process provided on the lower side of the support cylinder 2 (FIG. 2 (e)) and supplied to the next process.
In the case of the device of the present invention, one long thin pipe 10 is placed in the groove 5 among the many long thin pipes 10 placed randomly on the support cylinder 2 and the movable support member 4. The opening / closing operation of the movable support member is repeated until it is accommodated.

  Since the apparatus of the present invention can easily leave only one long thin pipe from the long thin pipes placed at random on the support cylinder simply by opening and closing the movable support member. It is possible to easily and reliably separate the long thin pipes entangled one by one. In addition, even when a piping component such as a nut is inserted near the end, it is possible to smoothly unravel one long thin pipe without the piping component being caught. There is no risk of damaging piping parts such as pipes and nuts or bending long thin pipes. Therefore, this invention apparatus is fully applicable not only to a pipe but to a long solid bar etc.
