Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a transfer device in a transfer press.

Prior art and its problems A transfer device has a feed bar, and a finger that can be opened and closed is attached to the feed bar.

Conventionally, the fingers were opened and closed using a lever or the like using a direct-acting air cylinder, but since the direct-acting air cylinder was used, it required a large space and the workpiece If the shape or size changes, there are problems such as difficulty in adjusting the mounting position of the fingers.

The purpose of this invention is to provide a transfer device for a transfer press that solves the above problems.

Means for Solving the Problems In the transfer device of the transfer press according to this invention, the casing of the reversible rotary actuator is attached to the outer surface of one of the opposite side walls of the movable frame, and the output shaft thereof protrudes between the two side walls. ears are provided on the other outer surface of both side walls of the movable frame and on the outer surface of the casing, horizontal through holes are drilled in the ears parallel to both side walls, and a support rod is slidably inserted into the through holes. The guide tube is slidably fitted onto the support rod, the guide tube is fixed to the feed bar so that the support rod is perpendicular to the feed bar, and the movable frame has a pair of fingers that can be opened and closed and reversible rotation of the output shaft. It is equipped with an opening/closing mechanism that opens and closes the fingers based on the

An embodiment of the present invention will now be described with reference to the drawings.

The transfer device has a pair of left and right feed bars 11.

Here, front and rear refers to the side where the feed bar 11 advances in the forward direction, the opposite side to the rear (the upper side in Fig. 3 is the front, and the lower side is the rear), and left and right. is defined as facing forward.

Among the left and right feed bars 11, only the left feed bar 11 is shown throughout the drawings. The right feed bar differs from the left feed bar 11 only in its left and right directions.

A movable frame 12 is attached to the feeder 11 so as to be movable in the left and right directions. Movable frame 1
2 has opposite front and rear walls 13 and 14.
Drooping parts 15, 16 are provided at the right ends of both side walls 13, 14.
are provided, respectively, and a pair of horizontal pins 17, which are attached vertically across both hanging parts 15, 16,
A pair of upper and lower fingers 19 and 20 are each rotatably supported by 18 . Both fingers 19, 20
Sector gears 21 meshed with each other are provided at the base of the
22 are integrally provided. Among the upper and lower fingers 19 and 20, an upwardly protruding ear 23 is provided at the base of the upper finger 19.

A casing 25 of a backward reversible rotary actuator 24 is attached to the front surface of the front wall 13 of the front and rear walls 13, 14 of the movable frame 12. An output shaft 26 of the actuator 24 passes through the front side wall 13 and projects between the side walls 13 and 14.

A rear ear 2 is provided on the rear surface of the rear wall 16 of the movable frame 12.
7, front ears 28 are provided on the front surface of the casing 25 of the actuator 24, respectively. rear ear 2
7 has two upper and lower through holes 29, and the front ear 28 has one through hole.
Two through holes 30 are respectively opened in the left and right direction. A support shaft 31 is installed in these through holes 29 and 30.
are slidably inserted into each. rear ear 27
A set screw 32 is screwed into a portion of the front ear 28 corresponding to the through holes 29 and 30. A rear guide cylinder 33 is slidably fitted over the two support shafts 31 on the rear side, and a front guide cylinder 34 is fitted over the one support shaft 31 on the front side. The front and rear guide tubes 33, 34 have base plates 35, 36.
are provided integrally with each other, and the base plates 35 and 36 are fixed to the upper surface of the feed bar 11. A bolt 37 with a handle is screwed into a portion of the guide tubes 33, 34 corresponding to the support shaft 31.

Referring to FIGS. 4 and 5, an arm 41 is fixed to the output shaft 26 of the actuator 24. As shown in FIGS. One end of a link 42 is connected with a pin to the tip of the arm 41, and the other end is connected with a pin to the upwardly projecting ear 23 of the upper finger 19.

FIG. 4 shows the fingers 19 in a closed state,
20 is shown as a solid line, and a plate-shaped workpiece M is gripped at its tip. From this state, when the output shaft 26 of the actuator 24 rotates clockwise in FIG. 4, the link 42 is pulled leftward by the arm 41 and moves to the position shown by the chain line in the figure. Along with this, the upper finger 19
rotates counterclockwise in the figure, and the sector gears 21,
22 rotates the lower finger 20 clockwise, and both fingers 19 and 20 are in an open state as shown by the chain lines in the figure. Needless to say, when the output shaft 26 of the actuator 24 rotates counterclockwise from this state, the fingers 19 and 20 are closed again.

To change the distance between the left and right fingers 19 and 20, the first step is to loosen the set screw 32 and move the movable frame 12 together with the actuator 24. If further adjustment is necessary, the second step is to loosen the bolt 37 and move the support rod 31 in its length direction, thereby moving the movable frame 12 together with the support rod 31 together with the actuator 24. good.

Effects of the invention According to this invention, since a rotary actuator is used to open and close the fingers, it does not require a large space compared to the case of using a direct-acting air cylinder as explained at the beginning. The mechanism for opening and closing the fingers does not need to be large-scale.

Furthermore, since the movable frame is moved together with the actuator in order to adjust the distance between the left and right fingers, there is no need to remove the actuator from the movable frame, and the adjustment work can be easily performed.

Furthermore, when adjusting the distance between the left and right fingers, it can be done in two stages: when the support rod is moved and when it is not, so the adjustment width can be adjusted without the fingers interfering with the workpiece. can be made larger.
