Description

[Detailed description of the invention] Industrial application field This invention is an ironed product take-out device for receiving the ironed product that has passed through a die during ironing processing of aluminum pipes, etc., and transporting it to a predetermined position and taking it out. Regarding.

Conventional technology For example, as a method for manufacturing aluminum tubes that require a high degree of surface smoothness, such as aluminum photosensitive drums for electronic copying machines and laser beam printers, the so-called EI method, which involves ironing extruded aluminum tubes, has recently been introduced. has been adopted. In this manufacturing method, the ironed aluminum tube that has passed through the ironing die is received, transported to a predetermined position, and sent to the next cutting process, etc.
A device for removing ironed products may be used.

Conventionally, such a take-out device has been configured such that a single product receiver can be reciprocated from the receiving side at one end of the base body to the take-out side at the other end using a conveyance mechanism such as a rodless cylinder, and ironed products that have passed through a die and fallen. After receiving the product into the product receiver at one end of the base, drive the rodless cylinder to move the product receiver to the other end of the base to take out the product, and then return to the one end receiving position again. This operation was then repeated.

Problems to be solved by the invention However, with such conventional product take-out devices,
Since there was only one product receiver that moved back and forth on the base, after receiving the ironed product, the next ironing process could not be performed until the product receiver returned to the receiving position again. The time during this time became idle time, and production efficiency was poor.

This invention was made to solve this problem, and aims to improve production efficiency by eliminating idle time during ironing and performing continuous operation. This is an improved product take-out device.

Means for Solving the Problems In order to achieve the above object, this invention provides a plurality of product holders, each of which is configured to be able to reciprocate asynchronously in a parallel state, and one product holder. Even if the ironed product is received and moved to the take-out position, the next product receiver is arranged at the receiving position by the time the next ironing process is completed.

That is, this invention includes a plurality of product receivers 2a for receiving and transporting the ironed products A that have fallen.
2b, and conveying devices 3a, 3 that reciprocate each product receiver from a product receiving position at one end of the base 1 to a product takeout position at the other end of the base 1 in parallel and asynchronously.
After the first product receiver starts receiving and transporting the ironed product, the other empty product receivers that have returned to the receiving position at one end of the base will reach the falling position before the next ironed product falls. As if to come,
A moving device 1 for moving the conveying devices 3a and 3b
The present invention is directed to a device for taking out ironed products, which is characterized by having the following features.

Operation Even if the first product receiver 2a that received the ironed product A that has fallen is moved to the other end of the base to the extraction side by the transport device 3a, the other empty product receiver 2b will not be transported. One end is returned to the receiving side by the device 3b, and the transfer devices 3a and 3b are moved by the moving device 13, so that the product receiver is at the product drop position before the next ironed product drops. Placed. By continuously repeating this operation, at the end of the ironing process, one of the product receivers will be at the position where the ironed product falls. Therefore, ironing can be performed continuously without waiting until the product receiver returns.

Example Next, an example of this invention will be described.

In Figures 1 to 5, reference numeral 1 denotes a base arranged in an inclined state, 2a and 2b product receivers for receiving and transporting the ladder-processed products, and 3a and 3b each of the product receivers 2a and 2b. This is a rodless cylinder as a conveying device that moves from one end of the length direction to the other end on the upper surface of the base 1. Two inner and outer pieces are arranged side by side in the width direction of 1.

Each of the rodless cylinders 3a, 3b has a slit-shaped opening 4a, 4b formed along its length in the center of its upper surface, and the product receivers 2a, 2b are formed in the internal hollow part of the rodless cylinder. An opening 4 is provided in the movable body movably fitted to the
a, 4b in a vertical arrangement.
Then, by freely moving the internal moving body in the length direction of the rodless cylinders 3a, 3b by hydraulic pressure, pneumatic pressure, or other appropriate method, each product receiver 2a, 2b is moved from one end of the base 1 to the other end. It is assumed that the vehicle will be moved back and forth. Regarding this reciprocating movement, the two product holders move simultaneously and in opposite directions, that is, when one product holder 2a or 2b moves from the bottom end of the base to the top end, the other product holder 2b or 2a moves from the top end of the base. The rodless cylinders 3a and 3b are controlled to move to the lower end.

The product receivers 2a and 2b are formed into a cylindrical body so that the ironed product can be accommodated in a fitted state, and are made of synthetic resin such as vinyl chloride to prevent damage to the product surface due to contact. ing.

On the other hand, the rodless cylinders 3a and 3b are
Near both ends in the length direction, it is integrally fixed to vertically swinging brackets 7 and 8 via U-shaped brackets 5 and 6, respectively. Further, the upper swing bracket 7 is placed on the base 1 via a bearing 9, and is pivotally supported on the base by a pivot pin 10 provided at the center thereof so as to be rotatable within a plane. . Further, the lower swing bracket 8 is similarly placed on the base 1 via a bearing 11, and a rod 12 is attached to the lower swing bracket 8 so as to pass through the center thereof. protrudes downward through a through hole (not shown);
Cylinder 13 as a moving device fixed to a base
It is rotatably attached to the tip of the ram 14. Therefore, with this configuration, the rodless cylinders 3a and 3b pendulum within a certain range on the base about the pivot pin 10 of the upper swing bracket 7 due to the back and forth movement of the ram 14 due to the operation of the cylinder 13. It is designed to be able to rotate.
Note that reference numerals 15 and 15 are stoppers made of vertically rising pieces formed on both side edges of the base 1.

As shown in FIGS. 1 and 3, the base 1 is configured such that each product receiver 2a, 2b is at the lower limit position of the base when the aluminum pipe or the like that passes through the die 20 and falls. In order to receive the ironed product A, its installation position is determined in correspondence with the die position. And, Figures 1 and 2
As shown by the solid line in the figure, the rodless cylinder 3
At the position where a and 3b have rotated to the maximum inward (towards the cylinder 13), the product receiver 2a of the outer rodless cylinder 3a is positioned directly below the die to receive the ironed product, and vice versa. As shown by chain lines in Figure 2, when the rodless cylinders 3a, 3b rotate outward to the maximum, the product receiver 2b of the inner rodless cylinder 3b is positioned directly below the die to receive the product. . In addition, in FIG. 3, 21 is a punch for ironing.

Next, the operation of the illustrated embodiment will be explained.

First, the outer product receiver 2a is at the lower receiving position of the base 1, the outer product receiver 2b is at the upper take-out position, and the rodless cylinder 3
As shown in FIG. 4, a and 3b are assumed to be at intermediate positions in the width direction of the base 1. Next, the cylinder 13 is activated and the rodless cylinders 3a, 3b are rotated inward as shown by solid lines in FIGS. 1 and 2.
The product receiver 2a matches directly below the die.

In this state, the ironing process starts and the die 2
0, the ironed product A is placed in the product receiver 2 at the falling position, as shown in Figures 1 and 3.
received by a. After receiving the product, the rodless cylinders 3a and 3b are driven, and the outer product receiver 2a rises along the opening 4a, and at the same time, the inner product receiver 2b, which was waiting at the upper take-out position, also moves along the opening 4b. Start descending. When each product receiver reaches its upper and lower limit positions, the operation of the rodless cylinders 3a and 3b is stopped. The ironed product A is then taken out from the outer product receiver 2a that has stopped at the upper take-out position and is supplied to the next process.

On the other hand, the punch 21, which has been lowered due to the ironing process, rises after the ironing process is completed, and then descends again after setting the workpiece to perform the next ironing process. Since the position of the inner product receiver 2b that has stopped at the lower receiving position is shifted from the position where the product falls, the cylinder 13 will operate and the rodless cylinder 3a, by the end of the next ironing process. 3b is rotated outward to the maximum extent as shown by chain lines in FIGS. 1 and 2, so that the product receiver 2b is aligned with the product drop position directly below the die.

When the product receiver 2b receives the next ironed product, the product receiver 2b starts to rise and moves to the product take-out position, and at the same time, the empty product receiver 2a, which has been waiting after taking out the product, starts to descend. Start and move to product receiving position. After the movement of the product receivers 2a and 2b is completed, the rodless cylinders 3a and 3b are rotated inward by the operation of the cylinder 13 in preparation for the next ironing process, and the same operation is repeated thereafter. In this way, two product receivers 2
Since a and 2b move alternately, it is not necessary to stop the ironing process until one product receiver returns to the receiving side after moving to the take-out side.

In addition, although the case where two product receivers were used was shown in the said Example, it is not limited to this and three or more may be used. Furthermore, the transport device for the product receiver is not limited to a rodless cylinder, and the moving device for matching the position of the product receiver to the product dropping position is not limited to a cylinder, but may include other mechanical or electrical devices such as a motor. Mechanical means may also be used.

Effects of the invention Since this invention is as described above, even if the first product tray moves to the take-out position after receiving the ironed product, the other empty product trays will be at the product receiving position by the time the next ironing process is completed. Therefore, there is no need to stop the ironing process and wait until the first product receiver returns again. Therefore, the idle time during this period can be eliminated and ironing can be performed continuously, so that production efficiency can be significantly improved.
