Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a stacking device for stacking long materials conveyed in long materials line finishing equipment.

[Prior art]

Generally, in online finishing equipment, long materials are transported one by one by a conveyor such as a chain conveyor, stacked, and sent to a bundling process to bundle multiple long materials into a bundle. It's summery.

However, with conventional stacking devices, it is difficult to stack each long material in an orderly manner. For example, as shown in FIGS.
If the long book 1a is placed diagonally,
Alternatively, another long piece of material 1b is placed diagonally as shown by the broken line, and is sent to the bundling process as it is to be tied. For this reason, even though each individual long piece of material is an acceptable product, it becomes a defective product when it is tied into a bundle, and the worker has to untie it and retie it or straighten it. It was happening.

[Purpose of the invention]

The present invention aims to solve the above-mentioned conventional drawbacks, and provides a long material stacking device in which the transported long materials are placed on an arm member in an orderly manner, and the defect rate can be reduced as much as possible. This is what I am trying to do.

[Structure of the invention]

The long material stacking device of the present invention includes a machine base, an arm member attached to the machine base, and a long material stacking device mounted on the machine base so as to be movable in a direction of advancing and retreating from the arm member. A conveying device for conveying material, a supporting member having a substantially vertical stopper portion and a roof member spaced a predetermined distance from the front end of the conveying device, and a flexible member hanging from the roof member near the front end of the conveying device. A moving member is provided on the machine base so as to be movable in conjunction with the conveying device so that the distance between the stopper portion and the front end of the conveying device is always constant.

Here, the machine base is a fixed member fixed to the floor, and the machine base is provided with an arm member and a conveyance device. Further, the arm members are for receiving the elongated material conveyed by the conveying device, and at least two arm members are arranged in the axial direction of the elongated material. After a certain amount of long materials are placed on the arm member, it is necessary to bundle the stacked long materials, so it is preferable to lower the arm member by a certain distance. desirable. It may be configured such that it descends a certain distance and is placed on a separately provided roller, and then rises again and returns to its original position. Alternatively, multiple arm members may be moved at regular intervals on a substantially elliptical trajectory. It is also possible to provide a configuration in which the device is provided and rotated along the trajectory.

The conveyance device is a device for conveying the long material processed in the previous step to the position of the arm member, and is preferably a conveyor device using a chain or the like, but other devices such as a skid rail may be used. .

The front end of the transport device is provided with a device for moving the front end back and forth. This is to ensure that the elongated material of the arm member is evenly and uniformly placed in the recess where the elongated material is placed. Specifically, it is preferable that the movable body provided at the front end of the conveyance device be moved back and forth in the front and rear directions. Although it is sufficient to provide at least one conveyance device, it is better to provide two or more conveyance devices in the axial direction of the elongated material for smooth conveyance.

The flexible member reduces the falling speed when the long material falls onto the arm member, so that the flexible member is placed smoothly on the arm member, and prevents some of the long material from being placed diagonally. It is provided for the purpose of writing. Specifically, a chain is preferable as this flexible member, but other materials such as a string made of cloth or hemp rope with a weight suspended from the lower end may also be used. When using a chain, it is necessary to install the chain so that it is bent in the front-rear direction of the conveying device.
Otherwise, the lower end of the chain will not become entangled with the elongated material when the elongated material falls.

The flexible members affect the probability that the elongated material will be placed diagonally depending on their length, mounting position, number, etc. The results of various experiments have shown that the lower end of the flexible member hangs down to the bottom surface of the sprocket at the front end of the conveyor (that is, hangs approximately 15 cm below the position of the long material just before it falls). This is the best, and the preferred mounting position is a position where the vertical center line of the flexible member approximately coincides with the axis of the sprocket, and the number of flexible members is 2 or 3 per conveying device in the substantially coincident state.
It is best to provide one.

A stopper portion of the support member is provided at a certain distance (preferably about twice the diameter of the elongated material) away from the front end of the conveying device to limit movement of the elongated material when it falls. The support member is preferably moved back and forth by an air cylinder provided on the machine base, and in order to always maintain a constant distance from the front end of the transfer device, a movable body provided at the front end of the transfer device is moved back and forth. It is preferable to synchronize and control the air cylinder and the air cylinder for moving the support member back and forth. However, the air cylinder for moving the support member back and forth may be omitted, and both the support member and the flexible member may be attached to the movable body.

〔Effect of the invention〕

According to the present invention, when the long material sent from the previous process is placed on the arm member by the conveyance device, it collides with the support member that is a certain distance away from the front end of the conveyance device, and is flexible. Since the falling speed of the material is reduced by entangling it with the lower end of the material, it is uniformly and smoothly placed on the arm member, and therefore only a portion of the long materials placed in countless tiers is The phenomenon of being placed diagonally is drastically reduced. Therefore, since oblique objects are not bundled while still inside, the defect rate is drastically reduced, and the troublesome work of untying and re-binding the bundled items by the operator can be eliminated.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 3 is an overall front view showing one embodiment of the present invention.
In the figure, the reference numeral 10 indicates a machine, and the machine 10 includes:
A large chain 11 driven in the direction of the arrow a by a drive source (not shown) is mounted, and the chain 1
1 is provided with a plurality (four in this embodiment) of integrated arms 12A, 12B, 12C, and 12D (forming arm members of the present invention) at equal intervals from each other. Therefore, when the chain 11 moves, the arms 12A to 12D move integrally in the same direction.
However, it does not always move at a constant speed; it repeats the action of stopping for a certain period of time and then moving for a certain period of time, as will be described later in the explanation of its operation. Such a chain 11 and a plurality of integrated arms 12A to 12D
The device consisting of is named arm device A.

A conveyor device B, which constitutes the conveyance device of the present invention, is installed on the left side of the machine base 10 in FIG.
The conveyor device B places a long material 13 on a chain 14 and conveys it in the direction of arrow b as shown in the figure.
It functions to be placed on the recess 12a of the accumulation arm 12A. Here, the arm device A is a third
A plurality of pieces (specifically, 6 pieces) are provided at equal intervals in the direction perpendicular to the plane of the paper in the figure, and they are configured to rotate in synchronization in the direction of the arrow a. For example, the arm 12A has the height shown in the figure. 6 when in
The arms 12A of the arm devices A are all configured to have the same height.
Therefore, the elongated material 13 is placed horizontally in the recess 12a.

The conveyor device B is provided with a plurality of fixed sprockets 15, 16, 17 whose axes do not move, and movable sprockets 18, 19 which can move in the horizontal direction. Also, the movable sprocket 18,1
A movable body 18A that is movable in the left and right direction together with the movable body 9 is provided, and this movable body 18A is moved by an air cylinder (not shown). Because of this,
Front end of chain 14 (right end in Figure 3)
14a can move forward and backward. FIG. 3 shows the state at the frontmost position, and when it is at the rearmost position, it is as shown by the solid line in FIG. The chain 14 is driven in the direction of the arrow by the sprocket 15.
This is done by a motor (not shown) provided at the back end of the shaft 15a in the direction perpendicular to the plane of the drawing.

As shown in FIG. 4, an air cylinder 21 is fixed to the top of the machine base 10. The air cylinder 21
A support 23 (constituting the support member of the present invention) is fixed to the tip of the piston 22 so that it can move left and right integrally with the piston 22. The support body 23 and the collecting arm 12A are provided at a certain distance from each other as shown in FIG. 5, so that they do not interfere with each other.

The support body 23 consists of a vertical part 23a (forming the stopper part of the present invention) and a roof part 23b, the tip of the piston 22 is fixed to the vertical part 23a as described above, and a flexible member is attached to the roof part 23b. The upper ends of the barrel chains 24 are connected. The chain 2
In this embodiment, one each of 4 is attached to the positions A and B of the roof portion 23b in FIG. 5, and one each is similarly attached to the other positions C, D, H, and H. It's getting wet. Alternatively, it may be further provided between positions A and B. Note that the support body 23 and the chain 24 constitute a moving member of the present invention.

As shown in FIG. 4, in this embodiment, the chain 24 is in a position where its vertical center line always coincides with the axis 19a of the sprocket 19 (FIG. 4) in the hanging state (however, the center line is It may be located near the front end 14a of the chain 14). For this purpose, an air cylinder 21 for moving the support body 23 and the movable body 18A described above are required.
An air cylinder (not shown) for moving the air cylinders is synchronized, and compressed air is pumped into and released from both air cylinders at the same time, so that the support body 23 and the movable body 18A move by the same amount in the same direction. It's getting old. That is, the front end 14 of the conveyor device B
The distance d between a and the support body 23 is always constant. This interval d is the long material 13
The diameter should be about twice as large.

The conveyance rollers 25 shown between the collecting arms 12A and 12B in FIG. 3 are rotatably provided around their axes, and a plurality of conveyance rollers 25 are provided in the direction perpendicular to the plane of the paper in FIG. As will be described later in the explanation of the operation, a certain amount of the long material 13 is placed on the collecting arm 12A as shown in FIG. 13 is placed on the roller 25. In this case, in order to prevent the elongated material 13 from falling from both ends of the roller 25, a plurality of guide rollers 26 and 27 are provided in the direction perpendicular to the plane of the paper in FIG. Further, reference numeral 28 in FIGS. 3 and 4 is a hose for guiding compressed air to the air cylinder 21.

Now, referring to FIG. 6, the structure around the movable body 18A will be described. The movable body 18A is supported by shaft bodies 35 and 36 via holding members 31 and 32 and bearings 33 and 34. 35, 36
is supported by a frame 37 which is a fixed member. The holding members 31 and 32 have a circular cross section, and the movable body 18A
can reciprocate on the holding members 31 and 32 in a direction perpendicular to the plane of the paper. A shaft body 38 is provided at the lower part of the movable body 18A, and the sprocket 18 is rotatably mounted on this shaft body 38 via bearings 39, 40. A plurality of rollers 41 are provided on the upper surface of the frame 37 in a direction perpendicular to the plane of the paper,
The chain 14 is guided by this roller 41 and is continuous with the sprocket 18.

Next, the operation of the device of this embodiment will be described.

The long materials 13 placed on the conveyor device B in the previous step are conveyed in the direction of arrow b in FIG. 3 and placed one by one in the recess 12a of one accumulation arm 12A. The front end 14a of the conveyor device B gradually and integrally retreats from the frontmost position as shown in FIG. 3 as the movable body 18A advances and retreats, so that the long material 13 is placed intensively in one place. (Note that in this embodiment, the movable body 18A gradually retreats from the most forward position, but may also gradually advance from the most rearward position.)

In this case, the elongated material 13 collides with the lower end of the chain 24 immediately before falling into the recess 12a. That is, as shown in FIG. 7, due to the collision, the lower end of the chain 24 is bent in the direction of the elongated material 13, the falling speed is weakened, and the chain 24 is placed in the recess 12a. At the same time, the elongated material 13 collides with the vertical portion 23a of the support body 23, which acts as a stopper, so that as shown in FIG.
The phenomenon that the elongated material 13 is placed obliquely as shown in FIG. 2 is greatly reduced. Whether the chains 24 are mounted diagonally or not depends on the number of chains 24, their mounting positions,
The results of various experiments have shown that the vertical center line of the chain 24 coincides with the axis 19a of the sprocket 19, as shown in FIG. The best condition was when it hung down to the bottom.

When the long materials 13 are placed in a stacked manner (as shown in FIG. 1), the conveyor device B temporarily stops, and each of the collecting arms 12A to 12D starts to move, and the arm 12A moves to the position of the roller 25. When passing through, the stacked long material 13 is placed on the roller 25. Each of the arms 12A to 12D moves further until arm 12D reaches the position of arm 12A in FIG. 3 and stops. On the other hand, the plurality of long materials 13 placed on the rollers 25 are bundled and transported to the next step (transported in a direction perpendicular to the plane of the paper in FIG. 3).
