Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a pipe take-out device that takes out pipes arranged at predetermined positions on a frame one by one in a pipe take-out direction perpendicular to the axial direction of the pipes.

[Conventional technology]

For example, in the manufacturing process of lined pipes in which the inner surface of metal pipes is lined with synthetic resin, there are cases where the metal pipes arranged on a stand must be taken out one by one and supplied to a station where post-processing is to be performed. However, if a worker were to take out the pipe in such a case, it would be time-consuming and would go against the demands for automation in the manufacturing process. Therefore, various devices have been used in the past in order to automate such pipe removal work. An example of this is one that utilizes rolling pipes. This involves aligning and arranging the pipes on an inclined pedestal, and placing a first stopper member for the front-row pipes and a second stopper member for the rear-row pipes at predetermined positions near the front bottom of the mount in front and back directions. The stopper members are arranged such that each stopper member can be swung by an air cylinder or the like so that each stopper member can selectively take either a pipe passing position or a pipe blocking position. According to this, from the initial state in which the first and second stopper members block the pipes in the front row and the pipes in the rear row, respectively, the first stopper member is moved to the pipe passing position and the second stopper member is moved to the pipe passing position. When the member is in the knob blocking position,
The pipes in the front row roll on an inclined pedestal and are taken out to the front. After that, if the first stopper member is set to the pipe blocking position and the second stopper member is set to the pipe passing position, the pipes in the rear row will roll to the blocking position of the first stopper member and return to the original state. Therefore, in this way, the pipe can be taken out one by one.

[Problems to be Solved by the Invention] However, according to the conventional pipe take-out device as described above, when the pipe in the front row (the pipe to be taken out) is rolled and taken out, it is difficult to prevent the pipes in the rear row from rolling continuously. As mentioned above, in addition to the first stopper member for the front row pipe, a second stopper member for the rear row pipe must be provided. Therefore, not only are at least two stopper members required before and after the pipe extraction position, but also
At least two sets of equipment, such as air cylinders and link mechanisms, are required, which increases cost and space. In addition, since the work of taking out only the pipe in the front row of pipes that are about to roll on the inclined frame relies on switching the blocking positions of the first and second stopper members, the second stopper member in the back row If the pipes cannot be properly stopped at a predetermined position, multiple pipes will be taken out, which may cause problems in subsequent processes. The present invention has been made in view of the above-mentioned conventional circumstances, and is intended to be used as a device that can automate the pipe removal work, and has a simple configuration that allows pipes arranged on a stand to be taken out one by one in a predetermined direction. It is an object of the present invention to provide a pipe take-out device that can reliably take out pipes.

[Means to solve the problem]

In order to achieve the above object, the present invention is a pipe take-out device that takes out pipes arranged on a pedestal one by one in a pipe take-out direction perpendicular to the axial direction thereof, and is characterized in that it is configured as follows. In other words, there is a rotating shaft that is provided parallel to the pipe axis direction at the pipe take-out part and is rotatable, and a pipe that is attached to this rotating shaft and extends in the pipe take-out direction and that is mounted on a pedestal at the rear end. The tilting arm is provided with a claw portion that can be inserted into the tilting arm, and a drive means for rotating the rotary wheel to tilt the tilting arm back and forth. When the tilting arm is tilted forward and downward by the driving means, the claw part enters between the first row of pipes on the mount and the second row of pipes, and the front row of pipes moves on the tilting arm in the pipe removal direction. The rear end of the tilting arm is arranged at a predetermined position below the pipe alignment surface so as to be able to roll. In this case, it is preferable that the pedestal be slightly inclined so that when the front row of pipes on it are stopped at the front end of the pedestal, the rear row of pipes will align themselves.

[Function] In the pipe take-out device configured as above,
With the rear end of the tilting arm positioned at a predetermined position below the alignment surface of the pipes aligned on the pedestal, the rotation shaft is rotated by the drive means in a direction to tilt the arm forward and downward. , the tilting arm attached to the shaft is tilted, and the rear end of the tilting arm is raised, while the front end of the tilting arm is lowered. When the rear end of the tilting arm is raised, the claw formed on the rear end enters between the pipe in the front row and the pipe in the rear row on the pedestal, causing the pipe in the front row to tilt. It is moved onto the arm, and in that state it rolls on the tilting arm in the direction of pipe removal. Therefore, according to the above configuration, the pipe in the front row on the pedestal can be moved by simply rotating the pivot shaft by a predetermined amount in a predetermined direction around its axis and tilting or swinging the tilting arm. It is possible to reliably take out one pipe at a time in the pipe removal direction perpendicular to the pipe axis direction. [Example] The present invention will be described in detail below. As shown in FIG. 1, the pipe take-out device l according to this embodiment includes a pedestal 2 on which a plurality of pipes P...P are arranged.
Support column 3 placed near the front end (pipe take-out part)
and is rotatably supported by this support 3 in the pipe axial direction (
A rotating shaft 4 extending parallel to the direction perpendicular to the plane of the paper; a tilting arm 5 attached to the rotating shaft 4 extending in a direction perpendicular to the rotating shaft;
A drive arm 6 whose one end is attached to the rotation shaft 4 so as to be located on the front side in the drawing, and a drive air cylinder 7 which rotates the rotation shaft 4 to a predetermined state via the drive arm 6. has. Here, a plurality of tilting arms 5 are provided along the axial direction of the rotation shaft 4 at a predetermined interval from each other. The front end of the pedestal 2 is supported via a cylinder 9 by a frame 8 provided at the front and lower part of the frame 2, and is slightly inclined so that the front end of the pedestal 2 is downward facing the garden (downwards to the left in the drawing). has been done. A stopper member IO is removably provided at the front end of the pedestal 2, and the pipe P rolling from the right side of the pedestal 2 in the figure is blocked by the stopper member 10, and the pipe P shown in FIG. They are arranged in a predetermined position. The pedestal 2 in this embodiment is configured such that its inclination angle can be adjusted as necessary by adjusting the amount of protrusion of the piston rod 9a in the cylinder 9. Further, the driving air cylinder 7 has a cylinder portion 7a.
The rear end is rotatably connected to the support column 3, and the tip of a piston rod portion 7b protruding from the cylinder portion 7a is rotatably connected to the other end of the drive arm 6. When the piston rod portion 7b protrudes from the cylinder portion 7a by a predetermined amount, the rotation shaft 4
is rotated by a predetermined amount in the direction of arrow B around its axis, and conversely, when the piston rod portion 7b retreats, the rotation shaft 4 is rotated in the direction of arrow B.
It can be rotated by a predetermined amount in the direction. On the other hand, the front end 5a of the tilting arm 5 is located in front of the front end of the pedestal 2, and the rear end 5b is located at a predetermined position below the pipe alignment surface. A claw portion 5c that can be inserted between a predetermined pipe P1.22 on P2 is provided in a protruding manner. The device is configured to swing back and forth around the axis as the rotation shaft 4 rotates, but in that case, especially when the front end is lowered, the rear end portion 5b becomes the front end portion. 5a, the claw portion 5c enters between the pipe P1 in the front row on the pedestal 2 and the pipe P2 in the rear row, and the pipe P1 in the front row is lifted onto the tilting arm 5 and lifted onto the arm. its front end 5a
It is designed to roll toward the side, that is, toward the pipe removal direction (see Figure 2). In this embodiment, a receiving part 11 is provided in front of the tilting arm 5, and the receiving part 11 is adapted to receive the pipe P1 rolling on the tilting arm 5 at a predetermined position. Next, the operation of this embodiment will be explained. Now, as shown in FIG. 1, with the rear end 5b of the tilting arm 5 positioned below the pedestal 2, a plurality of pipes P... When P is supplied,
These pipes P...P roll on the pedestal 2, and the pipe P in the front row comes into contact with the stopper member 10, so that they are aligned in a predetermined state on the pedestal 2. Next, in this state, the piston rod portion 7b of the driving air cylinder 7 protrudes by a predetermined amount, so that the driving arm 6, the rotating shaft 4, and the tilting arm 5 move around the axis of the rotating shaft 4 as shown in the arrow. Rotates integrally in direction B. As a result, the second
As shown in the figure, the front end 5a of the tilting arm 5 is lowered while the rear end 5b is raised. The pipe P in the front row is moved onto the tilting arm 5 by entering between the pipes P2 in the row (as shown by the chain line in FIG. 1). Then, when the tilting arm 5 is tilted forward, the pipe P[ in the front row moved onto the tilting arm 5 in this way rolls on the arm toward its front end 5a, and Receiving part 1 provided in front of the tilting arm 5

When the pipe P1 in the front row of P is removed from the receiving part 1, the piston rod part 7b of the driving air cylinder 7 retreats to the initial position, and the tilting arm 5, etc. It returns to its original state (the state shown by the solid line in FIG. 1) again. Then, by further repeating the above operation, the pipe P2 in the front row on the pedestal 2 is transferred to the receiving section 11 again. The pipes P...P arranged on the pedestal 2 in this manner are sequentially taken out one by one to the receiving section 11. Therefore, according to the above configuration, the pipes P...
can be reliably taken out one by one in the pipe removal direction perpendicular to the pipe axis direction. In the above embodiment, either a stopper member 10 of a predetermined size is attached so that the pipe P1 in the front row stops at a predetermined position at the front end of the mount, or a pipe having an outer diameter different from that shown in the figure is mounted on the mount. 2, by attaching a stopper member corresponding to the outer diameter of the pipe, it can be supplied to a predetermined position on the pedestal 2, that is, the tilting arm 5.
The pipes can be aligned at a position where the claw portion 5c can fit between the pipes in the front row and the pipes in the rear row.

【Effect of the invention】
