Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for conveying a moon from a certain arbitrary position to another position in a press machine, for example from a first processing position to a second processing position.

More specifically, the present invention relates to a conveyance device that can convey a material in response to the non-uniformity even if the distance between molds or the height of the molds in a press machine is non-uniform.

In a press machine, a transfer device is known as a device that conveys a material from a first processing position to a second processing position, for example. Conventional transfer devices are constructed by attaching material suction devices at equal intervals to a foot bar that extends parallel to the material conveyance direction, and the foot bar reciprocates horizontally and up and down over a fixed distance. Ta.

Therefore, conventionally, materials at a plurality of processing positions are simultaneously attracted and transported by the lowering of the foot bar. Therefore, in the past, a plurality of processing positions had to be equidistant, and the heights of each processing position had to be the same. Therefore, in the past, it was quite difficult to deal with changes in the size of the mold during the processing process.

The present invention was created in view of the conventional problems as described above, and the apparatus according to the present invention is configured to easily cope with cases where the distances and heights of multiple processing positions are variously different. It is. In other words, a plurality of movable bodies are individually movably attached to a guide body extending parallel to the material conveyance direction, and
Each movable body is provided with a suction device on each arm that is movable up and down.

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

The material conveying device @ 1 according to the present invention is a gear part or a front face of a press that performs processing in multiple steps with one press, or a press and a press in the case where multiple presses for one step are connected to perform processing in multiple steps. It is installed between the FIG. 1 shows an example in which the device is mounted on a press. The press 3 is a general press, and has a C-shaped frame 5 with a bolster 7 attached thereto and a ram 9 attached so as to be vertically movable. Since this type of press is known,
A detailed explanation thereof will be omitted.

The material conveying device 1 is installed in a C-shaped gear part 11 of a frame 5 in a press 3.

However, the mounting position of the material conveying device 1 is at the gap portion 1.
The number of presses is not limited to one, and as described above, it may be provided between presses that connect a plurality of presses.

The material conveying device 1 includes a plurality of servo arm units 15 detachably and individually movably attached to a guide body 13 extending parallel to the direction of conveying the material in the press force and loe line. As is clear from FIG. 2, the guide body 13 has a channel steel-like cross-sectional shape, and a guide portion 17 parallel to the material conveyance direction is provided on the upper surface of the lower plate 13L. ing. The guide portion 17 is
In this example, it is formed into a guide rail shape, but
It may be formed in the shape of a guide groove. A hole 19 parallel to the guide portion 17 is provided on the lower surface of the upper plate 13U of the guide body 13.

The servo arm unit 15 includes a movable body 21 that can reciprocate along a guide portion 17. An engaging part 23 movably engaged with the guide part 17 is formed at the lower part of the movable body 21, and a pinion 25 that engages with the rack 19 is rotatably attached to the upper part via a pin 27. It is. This pinion 25 has a first actuating device 2, such as a servo motor, attached to the movable body 21.
The output gear 33 attached to the output shaft 31 at 9 is in mesh. Therefore, by appropriately driving the first actuating device 29 and appropriately rotating the binion 25 via the output gear 33, the movable body 21 reciprocates (self-propelled) along the guide portion 17. The range of reciprocating movement can be set arbitrarily.

A vertical guide portion 35 is formed on the front side (right side in FIG. 2) of the movable main body 21. Although the upper and lower guide portions 35 are illustrated as having a groove shape, they are not limited to a spiral shape. A base portion of a single-shaped elevating body 37 is engaged with the vertical guide portion 35 so as to be vertically movable, and a rack portion 39 is formed in the elevating body 37 in the vertical direction. A pinion 45 attached to an output shaft 43 of a second actuating device 41 attached to the movable main body 21 meshes with this rack portion 39 . Therefore, the second
By appropriately operating the actuating device 41, the elevating body 37 can be moved up and down, and the range of the up and down movement can be set arbitrarily.

The base of an arm 47 extending forward is integrally fixed to the elevating body 37, and a suction device @49 such as a vacuum pad or an electromagnet is attached to the tip of the arm 47 so as to be movable up and down. .

This suction device 49 adsorbs or releases a material (not shown) when it is lowered together with the elevating body 37, and has the function of adsorbing the material and transporting it from one position to another. It is something that does.

The first actuating device 29, the second actuating device 41, and the suction device 49 in each servo arm unit 15 are operated under the control of an appropriate actuation control device (not shown) such as a numerical control device or a computer. Each servo arm unit 15 is individually controlled and operated so as not to interfere with each other.

In order to control the servo arm unit 15, it is sufficient to teach the operation, for example, as shown in FIG. 3, and to measure the interlocking with the press. That is, (1) teaches the arm origin to the first servo arm unit 15;

■ Teach the feed amount to mold A (first position).

■ Teach the lift-down amount, material adsorption timing, and lift-up amount.

■ Teach the amount of feed to mold B (second position).

■ Teach the amount of lift down, the timing of release of the material, and the amount of lift up.

■ Return to origin The same teaching is individually given to each of the required number of servo arm units 15, such as the second, third, etc., and the operation of each servo arm unit 15 is controlled by the rotary cam switch or the like in the press. The same operation is performed using control signals from other press control devices. That is, each servo arm unit 15 operates synchronously, and the operating speed is individually controlled in accordance with the feed amount.

Note that each servo arm unit 15 can be controlled by NG sub-control without using the teaching method described above.

As can be understood from the above description of the embodiments, according to the present invention, the horizontal movement of each movable body 21 and the vertical movement of each arm 47 in each servo arm unit 15 are individually controlled. Moreover, the movement range of each movable body 21 and the vertical movement range of each arm 47 can be set individually. Therefore, even if the distances, heights, etc. between a plurality of processing positions are uneven, it can be easily handled. Therefore, mold installation and operation preparation (setup) can be performed more easily and in a shorter time than in the past.

Furthermore, by attaching and detaching the servo arm unit 15 to and from the guide body 13 in accordance with the number of processing steps, it is possible to easily respond to changes in the number of processing steps.

The configuration in which the movable body 21 is reciprocated along the guide portion 17 and the configuration in which the elevating body 37 is moved up and down are not limited to the above-mentioned rack and binion mechanism, but may be implemented in various configurations. For example, as shown in FIG. 4, a stator 51 is installed on the guide body 13, and a coil 5
3 or a near motor configuration. Further, the elevating mechanism for the elevating body 37 may be a rod-type linear motor with the primary side 55 having a cylindrical shape. In the embodiment illustrated in FIG. 4, a rail member 57 is provided in place of the rack on the upper plate 13LJ of the guide body 13, and rollers 59 attached to the movable body 21 can be freely moved on three sides of the rail member 57. It is in contact with.

Note that this invention is not limited to the above-mentioned embodiments,
By making appropriate changes, it can be implemented in other ways.
