Abstract

PURPOSE:To selectively use a cylinder stroke to upper, medium and lower positions, in the captioned device wherein a material is received from and delivered to a roller conveyer by combined use of two independent cylinders, by interposing an escape part to connect the both cylinders. CONSTITUTION:At acceptance of a steel pipe A, an arm 5 is set to a standby position (a) and the pipe is received to a receiving part 5a. Then a piston rod 8b of a cylinder device 8 is extended to an upper limit. Here a lever 6 does not act before a pin 12 is adapted to the bottom end of a long hole 10 because of an escape part C of the pin 12 formed by the long hole 10 in a connection part B between the piston rod 8b and the lever 6. After the pin 12 is pressed to the bottom end, the lever 6 is pushed upward, and the arm 5 is fixedly placed to a downward lower receiving position (b). Similarly at delivery, the pipe is delivered by a delivery cylinder not shown in the drawing similar to that provided with an escape by the long hole 10 and the pin 12. In this way, a stroke can be selected to three of upper, medium and lower stages.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material receiving and dispensing device, generally referred to as an easy-down (material receiving and kick-out), and more particularly to a material receiving and dispensing device for receiving and discharging materials to and from the same roller conveyor. This invention relates to a device in which a total of two independently acting cylinder devices are used.

4-0 When a roller conveyor is required to have both the functions of receiving and discharging materials, conventionally, a device with each function is installed independently, or a device with both functions is installed. Either. The former has the disadvantage that there are two types of devices, which increases the equipment cost, and the latter has the disadvantage that there is usually only one cylinder device that operates the rotating arm, so the stroke of the cylinder device In addition to the upper and lower limits, it is necessary to control the intermediate six levels, and it is necessary to detect and select the position of the fault, so failures are more likely to occur, and the equipment cost is not much different than the former case. .

The present invention was made in order to eliminate the above-mentioned drawbacks, and is an apparatus having both the functions of receiving and discharging materials,
Moreover, by providing a relief part in the connecting part between the two cylinder devices and the rotating arm, the operation of one cylinder device is not restricted by the other cylinder device, and the stroke limit of the above six steps is provided. The object of the present invention is to provide a material receiving and dispensing device that enables switching of materials.

The present invention rotatably supports an arm that serves both for receiving and discharging materials to the same roller conveyor, connects two cylinder devices to a lever that operates the arm, and connects one cylinder to the connecting portion of the two cylinder devices. An embodiment of the material receiving and dispensing device is described below with reference to the drawings, which is characterized in that the operation of one cylinder device is not restricted by the other cylinder device.

Figures 1 to 5 show the case of receiving and discharging steel pipes as materials, and in these figures (1)

This is a roller conveyor (1
) should be provided at two or more locations in the pass line direction, and if it can be rotated in the vertical direction around the rotation axis (3), the rotation axis (6) may be a fixed axis. It's okay to have one. In this embodiment, a pivot shaft (6) is rotated by rotating a lever to be described later, and thereby the arm (5) is configured to rotate in the vertical direction. For this purpose, the easy-down lever (6) and the kick-out lever (7) are fixed at their proximal ends to the rotating arm (6) at a position opposite to the arm (9). ) and (7) may be arranged in an appropriate number in the axial direction of the rotating shaft (6).

(9) have sufficient length to extend in opposite directions so as not to be restrained by (9). That is, in the standby position (a) of the arm (5) shown by the solid line in FIGS. 4 and 5,
/ The piston rod (8b) of the cylinder device (8) has been shortened to the toe limit position, and therefore the pin (
12) is the elongated hole (10) at the tip of the piston rod (8b).
) is in contact with the upper inner edge of the On the other hand, this standby position (a
), the piston rod (9b) of the cylinder device (9) is extended to the upper limit position, so that the lever (force bottle (16) It is in contact with the inner end.

The standby position f# (a) of this arm (5) is
5) when the bent receiving part (5a) is located slightly above the conveying surface (1&) of the roller conveyor (1), and when the receiving part (5a) is rotated downward from the conveying surface (1&). The receiving position (b) of the arm (5) is when the arm has moved, and the receiving position (b) of the arm (5) is when it has rotated further upwards than the standby position (a).
) is the payout position (c).

By the way, an inclined skid (15) for receiving the steel pipe (A) onto the arm (5) is provided close to the side facing the free end of the arm (9). ) on the extension line of the upper surface (15a) l of the arm (4
The inclined surface on the free end side of the receiving part (5a) is located at the standby position (, ) of the holding part (5a).

On the other hand, on the side facing the base end of the arm (9), there are a number of inclined rails (18) close together at appropriate intervals for discharging and transferring the steel pipes (A) from the roller conveyor (1). The dispensing position of the arm (9) is located on the extension line of the nuclear inclined rail (18) η rail surface (18a).
The inclined surface on the base end side of the receiving portion (5a) in c) is located. In addition, the easy down lever (6) and the kickout lever (the forces are provided separately, but the positions of the easy down cylinder device [(8) and the kickout cylinder device 19) are shifted within the same lever. At least one lever adapted to act may be provided, and this lever may be constructed in one piece with the arm (5).

Next, the operation will be explained as follows when receiving the steel pipe (A).

The arm (5) is set to the standby position (a). The steel pipe (A) from the previous process is placed on the top surface of the inclined skid (15) (
15a) and rides on the receiving part (5a) of the arm etc.). Thereafter, compressed air is sent to the easy-down cylinder device (8) to extend the piston rod (8b) to the upper limit position. Then, since the relief part (C) of the bottle (12) by the elongated hole (10) extends downward at the connection part (J3) between the piston rond (8b) and the lever (6), the pinot (12) becomes elongated ( The lever (6) does not operate at all until the lever (6) comes into contact with the lower inner end of the long (10), but when the bottle (12) comes into contact with the lower inner end of the long (10), the lever (12) moves and the lever ( 6) Since the entire arm is pushed up slightly, the rotating shaft (lo) can be rotated accordingly, and the arm (51) can be rotated slightly downward and fixed at the receiving position (b).

During this period, the kick-out cylinder device (9) remains inactive, but the piston rond (9b) and the lever (7) are connected to each other (B') by a pin (16) formed by an elongated hole (11). ) extends upward, so even if lever G) is pushed up as described above, the bottle (16) of lever V) only moves within the relief part (C') and Accordingly, the cylinder device (9) itself tilts slightly about the pivot at the base end, but the operation of the other cylinder device 6) is not restricted at all by this cylinder device (9).

Therefore, the steel pipe (A) temporarily mounted on the arm (9) is next transferred to the roller conveyor (A) by the downward rotation of the arm (5).
1) Since the steel pipe (A) is transferred to the top, it is possible to receive the steel pipe (A) in this way, that is, to perform easy down. Note that the steel v(A) is conveyed to the next process by a roller conveyor (1).

Next, when the steel pipe (A) is discharged from the roller conveyor (1), it is done as follows.

First, the arm 6) is placed at the receiving position (b), the easy-down cylinder device (B) is operated as described above, and the steel pipe (toward the steel pipe) is stopped at a predetermined delivery position by the roller conveyor (1). . Furthermore, this cylinder device (8)
The arm (5) is raised to the standby position (, ) by the operation of the arm (5), and the steel pipe α) is temporarily supported by the arm (5)-H from above the roller conveyor (1). Then, compressed air is sent to the kick-out cylinder device (9) to shorten the piston rod (9b) to the lower limit position. Then, connect the piston rond (9b) and lever V) (
Specifically, the escape part (C') of the bottle (13) due to the elongated hole (11)
) extends upward, so the bottle (16) is inserted into the t-hole (11
) until the lever (V) comes into contact with the upper inner edge of the slot (11), the lever (V) will not operate, but if the bottle (16) comes into contact with the upper inner edge of the elongated hole (11), the lever (13) will move and the lever ( 6) Since it is pulled completely downward, the rotation shaft (6) is rotated and the arm (5
) can be rotated upward considerably and fixed at the dispensing position. Note that even in this case, while the kick-out cylinder device 19) is operating, the easy-down cylinder device 19) is inactive.
The connecting part between the piston rond (8b) and the lever (6) (
B) has a relief part (C) of the bottle (12) due to the long diameter (10).
) extends downward, so even if the lever (7) is pulled down as described above, the bottle (12) of the lever (6) moves within the relief part 0, thereby tilting the cylinder device (8) itself. This cylinder device (8) does not restrict the operation of the other cylinder device Q).

Therefore, the arm (steel pipe <A temporarily mounted on 5) is
When the arm (5) further rotates upward and reaches the dispensing position (C), the inclined surface on the proximal side of the receiving part (5a) slopes downward, so that the steel pipe prisoner) is rolled away from the receiving part (5&). It moves and escapes, and is discharged onto the inclined rail (18) which is continuous with this inclined arm 6).

As described above, the steel pipe (A) from the roller conveyor (1)
) can be paid out, ie, kicked out.

In addition, in the present invention, the lengths of the respective connecting portions (B), (target relief portions C), and (σ) of the levers (6), (7) and the cylinder devices (8), (9) are the same as those of the levers (6), (7) and the cylinder devices (8), (9). ), (7), and may be designed as appropriate depending on the length and rotation angle, and it goes without saying that it includes those formed integrally with the lever G) and the lever arm 6).

As explained above, according to the present invention, the two cylinder devices for easy down and kick out are connected by providing a relief part in the lever and the connecting part that actuates the arm, so that the cylinder devices can be operated independently. By simply operating up to the stroke limit, the operation of one cylinder device is not restricted by the other cylinder device at all due to the relief portion, and the arm can be switched to each of the standby, receiving, and dispensing positions in six stages. Therefore, this switching control is simple, there are few failures, and the equipment cost is low.
