JPS5828452A - Double pitch transfer device of a transfer machine - Google Patents

Abstract

PURPOSE:To reduce idle stations in a transfer machine, in which the work to be processed is fed at a constant pitch in box movement, by installing a moving work receptacle on the transfer bar being interlocked with the motion of the bar. CONSTITUTION:When a transfer bar 1 rises, a rod 3 retracts to the right. This movement is transmitted to a rotary plate 15 through a lever 14 and a coupling member 17, and this rotary plate 15 rotates counterclockwise round a fulcrum pin 16 to actuate a pin's 12 rise along a long hole 13a in the fixation plate 13 with the aid of pin's 12 detention with a lon hole 15a. A swing arm 9 rises smoothly following the rise of a moving work receptacle 8. When the transfer bar 1 advances by a specified stroke, it is transmitted to a bracket 10, rod 11 and swing arm 9 and the moving work receptacle 8 slides on the transfer bar 1 to the left, where the motion is combined with that of the transfer bar 1 to transport the work at double pitches.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that a transver, in which a plurality of workpiece receivers are fixed at equal pitches, sequentially repeats upward, forward, downward, and backward operations to transfer workpieces to two fixed workpiece receivers for machining. The present invention relates to an improvement of a rotary transfer machine.

Conventionally, in this type of transfer machine, when reducing the number of stations, there has been a tendency to increase the transfer pitch, resulting in an increase in the size of the entire machine and the need to increase the space required. Furthermore, if the transfer pitch is made smaller, the number of idle stations will increase and dead work will increase. Therefore, the transfer pitch is determined within the constraints of space, processing, maintenance, etc., but even when towed, the machine tends to have an idle station, which causes dead work, which is a problem.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to achieve idle speed by utilizing the movement of the transerver and the rod for raising and lowering the transerver, without using any other power. To provide a double pitch transfer device for a transfer machine that reduces dead work by reducing the number of stations. The feature is that the transserver is moved back and forth by the drive source, and the scissors transserver is moved up and down by the drive source (-) to the idle station on the transserver using the movement of the rod that is moved up and down via the intermediate member. The workpiece receiver that becomes the workpiece receiver is deleted, and the workpiece receiver after the workpiece receiver is made into a movable workpiece receiver that can slide on the transserver, and the movable workpiece receiver is attached to the lever attached to the rod or the movable workpiece receiver. In addition, double pitch movement is possible using a swinging arm connected to the transserver.

Hereinafter, one embodiment of the present invention will be described based on FIG.

Jll! 1 to 3C: In FIGS. 1 to 3C, l denotes a plurality of workpiece receivers 2, 2 . % 3 is a rod that allows the transver l to be moved up and down by a constant stroke via an intermediate member 5 by a driving source 4. There are two tranny pals, which extend parallel to each other in the front and back direction. It transports the workpiece 6 above the receiver 7 (-), then descends to place the workpiece 6 on the fixed workpiece receiver 7 for processing, and finally retreats and returns to its original position in preparation for transporting the next workpiece 6. .

9 is a swinging arm whose upper end is rotatably provided on the movable workpiece receiver 8. The intermediate portion C2 has one end fixed to a bracket 10 integrally attached to the transserver 11, and the other end of the rod member 11 is pivotally supported. A bottle 12 is installed at the lower end of the swinging arm 9, and the bottle 12 engages with the elongated portion 13& of the fixed plate 13 so as to be able to move up and down. On the other hand, lever 1 is attached to rod 3.
4 is attached at its upper end so as to be rotatable with respect to the rod 3, and in the middle part of this lever 14,
One end of the connecting member 17 that connects the rotating plate 15 which has a length 151L that engages with the bin 12 and is rotatably arranged around the fulcrum bin 16. The sides are carved.

When transver l rises from the lowered state, rod 3
moves backward (moves to the right in the figure), and this movement is caused by lever 14. It is transmitted to the rotating plate 1g via the connecting member 17, and the rotating plate 15 rotates counterclockwise around the fulcrum pin 16, and due to the engagement between the elongated hole 151L and the pin 12,
The bottle 12 rests on the long length 13 & of the identification plate 13 and rises.

Then, the swing arm 9 rises. Next, when the transerver 1 moves forward by a predetermined stroke, the movement is transmitted to the lifting arm 9 (2) via the transerver 14, the attached bracket lO, and the rod member 11, and the movable workpiece receiver 8 moves to the transermo. This operation causes the leftward stroke of the transver l, the transthermal movement of the movable workpiece receiver 8, and the transport of the workpiece 6 at double pitches.

Next, the transver l is lowered, which is done by moving the rod 3 to the left. At this time, it is the reverse of the clockwise movement of the rod 3 described above, and the moving plate 15 moves clockwise and twice around the fulcrum pin 16 at the center a, and the pin 12 moves through the elongated hole 131.
The swinging arm 9 smoothly follows the descent C2 of the transver l and descends. After that, the transserver l retreats, but its operation is similar to that of the transerver l described above.
This is the reverse movement of the forward motion of the transver l, and the rightward stroke of the transver l itself and the movable workpiece receiver 8 via the swing arm 9.
Slide straw to the right - in Figure 3, mark 18
What is shown in C: is the case where there are other idle stations as described above in the transfer machine (;
, is a connecting rod that connects the movable workpiece receiver provided at that location and the main movable workpiece receiver 8, and this connecting rod 1
8, the number of similar idle stations on the transfer machine can be eliminated with just one device. In addition, in this example book, the movable workpiece receiver 8
Although an example has been described in which the swing arm 9 and the rod member 11 are attached to each other by adjusting their positions, it is also possible to move the movable workpiece receiver 8 by three times the pitch, four times the pitch, or the like.

According to the present invention as described above, it is possible to reduce the number of idle stations by using the drive source of the transfer machine itself without using any other power, and to reduce the number of dead works. It is possible to provide a double-bit transfer device for a transfer machine that can reduce the amount of energy.
