Description

[Detailed description of the invention] (Industrial application field) This invention relates to a workpiece transfer device equipped with two workloading devices, in which workpieces of different types are transported on different transport lines. The workpieces can be directly transferred to one lifting conveyance device without going through another work loading device.

(Prior Art) For example, as shown in FIG. 2, in the transport lines A and B whose transport end positions are located close to each other, by the work loading devices 1 and 2 provided at the respective transport end positions, In the case where each workpiece is taken out of the transport path and each of the taken out workpieces is transported to a predetermined position by a lifting transport device 3 shared by both works, most of the conventional techniques The workpiece taken out of the transport path by the work loading device 1 located close to the upper transport device 3 is delivered directly to the lifting transport device 3, while the workpiece is transferred away from the lifting transport device 3. The workpiece taken out of the transport path by the located work loading device 2 is once transferred to the work loading device 1 and then handed over to the lifting transport device 3 based on the action of the work loading device 1. It is said that

Here, conventional workload devices 1 and 2 configured to provide such functions include:
For example, there is one shown in front view in FIG.

In the figure, a work loading device 1 disposed at the transport end position of a transport line A pivots one end of a work support frame 5 to the upper end of a bracket 4.
The cylinder 6 attached to the cylinder 6 may be able to swing between the solid line position and the imaginary line position in the figure.On the workpiece support frame, there is also a workpiece receiving post 7 that positions and supports the workpiece W, and a workpiece receiving post 7 that positions and supports the workpiece W. The workpiece W supported by the workpiece receiving post 7 is
It is constructed by providing a clamper 8 that clamps the workpiece on the workpiece receiving post 7.

Further, the work loading device 2 disposed at the conveyance end position of the conveyance line B has a base 10 disposed on a pedestal 9, a pinion 12 driven by a motor 11, and a rack 13 meshing with the pinion 12. A slide frame 15 is supported on the base 10 by guide rollers 14, and this slide frame 15 is connected to a pinion 17 driven by a motor 16, and a pinion 17 driven by a motor 16. By means of a rack 18 meshing with 17, the workload loading device 1 is
Further, a work receiving post 19 for positioning and supporting the work W is provided on the slide frame 15.

Of these respective work loading devices 1 and 2, the work loading device 1 delivers the workpiece W transported onto the workpiece receiving post 7 to the hoisting and transporting device 3 in the following manner.

Initially, the workpiece W, which is positioned and supported by the workpiece receiving post 7 of the workpiece support frame 5 at the position shown by the solid line in the figure, is clamped by the clamper 8, and then, by the operation of the cylinder 6, the workpiece The support frame 5 and the workpiece W are swung to the position shown by the imaginary line in the figure, and there, the engaging claw 3a of the hoisting and conveying device 3 is engaged with the workpiece W, and the clamper 8 is unclamped to unclamp the workpiece W. Released from the workload device 1.

The work loading device 1 that has completed the delivery of one workpiece W in this manner waits for the next delivery operation by returning the workpiece support frame 5 to the position shown by the solid line in the figure, and also waits for the next delivery operation. The lifting transport device 3 that has received the workpiece W transports the workpiece W to a predetermined position.

On the one hand, the workload device 2
When transferring a workpiece W, which has been transported onto the workpiece receiving post 19 and is often of a different type from the workpiece W described above, to the lifting transport device 3, the base 10 is first moved based on the operation of the motor 11. By raising it relative to the pedestal 9, the slide frame 1
5 and the work W to a predetermined level,
Next, by operating the motor 16, the slide frame 15 and eventually the workpiece W are advanced to a position above the workpiece receiving post 7 of the workloading device 1 in the posture shown by the solid line in the figure, and the base 10 and the slide frame 15, the workpiece W on the workpiece receiving post 19 is transferred to the workpiece receiving post 7, and then the slide frame 15 is moved by the motor 16 to its initial stage shown by the solid line in the figure. Return to position.

By these things, one workload loading device 2 can be connected to the other workload loading device 1.
After completing the transfer of the workpiece W, the workpiece loading device 1 is operated in the same manner as described above to transfer the workpiece W to the hoisting and conveying device 3.

(Problem to be Solved by the Invention) However, in this conventional technology, in particular, in order to deliver the workpiece W transported on the transport line B to the lifting transport device 3, one of the work loading devices 2 is Therefore, it is necessary to once transfer the workpiece W taken out of the transport path to the other work loading device 1. For example, when installing a new transport line B for the existing transport line A, , there was a problem that the work loading device 1 on the conveyance line A had to be modified so that it could also position and hold the workpiece W conveyed on the conveyance line B. There was a problem in that the time required from the time when the workpiece W was taken out of the transport path until the end of the handover to the lifting transport device 3 became long, and the transport efficiency of the workpiece W was low.

This invention advantageously solves the problems of the prior art by individually and independently delivering each of the workpieces transported by each transport line to a single hoisting transport device. ,
By improving the work loading device for conveyance line B described in the conventional example, it is possible to directly transfer the workpiece conveyed by conveyance line B to the hoisting conveyance position. When newly installing B, other pre-existing transport line A
To provide a workpiece transfer device that eliminates the need for any modification of a workloading device for use in a conventional workpiece, and that can extremely quickly transfer a workpiece to a hoisting transfer device.

(Means for solving the problem) The workpiece transfer device of this invention is constructed with two workloading devices, one of which is closer to the hoisting transfer device. One end of the work support frame is pivotally supported at the upper end of the bracket, and the bracket is provided with driving means for swinging the work support frame, and the work support frame is provided with a work receiving post for positioning and supporting the work. The other work loading device is configured by providing a clamper for clamping the work, and the other work loading device is configured by pivoting a die frame on a pedestal, and swinging this guide frame in a vertical plane. A rotating drive means is provided on the frame, and a traveling base is provided on the guide frame, and this traveling base is
It is constructed by providing reciprocating drive means for moving forward and backward along the guide frame, and further providing a work receiving post and work holding means for positioning and holding the work on the traveling base.

(Function) In this workpiece transfer device, the workpiece transferred by the transfer line A described in the prior art is lifted and transferred in the same way as described above by one of the work loading devices near the lifting transfer device. The workpieces transported by the transport line B will be transferred to the equipment under the swinging of the guide frame based on the operation of the rotation drive means of the other workload loading equipment. , the workpiece is received on the traveling base and held by the workpiece holding means, and then the workpiece held on the traveling base is held by placing the guide frame in a horizontal position.
The workpiece is transferred to the hoisting transfer device, and the traveling base is advanced from the rear end position to the tip position of the guide frame, and there, the workpiece is engaged with the hooking claw of the hoisting transfer device, while the workpiece relative to the workpiece is By releasing the restraint of the clamping means, the workpiece can be directly and quickly delivered to the lifting conveyance device.

After the workpiece has been delivered in this way, the workpiece loading device moves the traveling base back to the rear end position of the guide frame and returns the guide frame to the swinging position, thereby transferring the next workpiece. Waiting for work.

In this way, here, the workpiece transported by the transport line B can be transported without causing any interference between it and the work loading device for the transport line A.
In addition, since the work can be transferred directly to the lifting transport device without waiting for the work of the workload loading device, even if a new transport line B is installed near the existing transport line A, the transport line Not only modification of the work loading device for A, but also stoppage of the transport line A can be made unnecessary, and furthermore, the time required for delivering the work can be sufficiently shortened.

(Example) This invention will be explained below based on illustrated examples.

FIG. 1 is a front view showing an embodiment of this invention, and 1 in FIG.

A cylinder 26, which is an example of rotational driving means for the guide frame 24, is connected to the arm 25 that projects downward from the guide frame 24.

The cylinder 26 here has its cylinder side end portion pivoted to the frame 22 and the piston rod 26a to the arm 25, so that when the piston rod 26a is retracted, the guide frame 24 is moved as shown in FIG. 1a. The piston rod 26a is maintained in a horizontal state, and when the piston rod 26a advances, the guide frame 24 is maintained in a tilted state with its rear end positioned downward, as shown in FIG. 1b.

And here again, on the guide frame 24,
A traveling base 27 is disposed movably along the guide frame 24, and the forward and backward movement of the traveling base 27 is controlled by a reciprocating drive means, such as a rodless cylinder 28, attached to the guide frame 24. Note that as the reciprocating drive means here, other known drive means such as a wire or chain drive means or a gear drive means can also be used. and the tip.

Here, the running base 27 in the illustrated example is configured to run on a guide frame by means of rollers 27a provided thereon.
It is also possible to make a rocking movement on the guide frame.

Furthermore, here, the first part of the guide frame 24 and the first part of the traveling base 27 is
A plurality of workpiece receiving posts 29 are provided that protrude upward from the tilted posture as shown in FIG. will be established.

The workload device 21 having such a configuration has the following features:
With the guide frame 24 and the traveling base 27 in the tilted postures as shown in FIG.
After holding by the action of 0, the guide frame 2
4 is placed in a horizontal position as shown in FIG. Figure 1a
As shown in FIG.
By engaging the workpiece W and releasing the restraint of the workpiece W by the clamper 30, the workpiece W is directly transferred to the hoisting and conveying device 3.

After the workpiece W has been delivered in this manner, the workpiece loading device 21 causes the traveling base 27 to travel to the rear end of the guide frame 24, and also causes the guide frame 24 to swing as shown in FIG. 1b. Waiting for the next handover operation of the work W.

Therefore, here, the work W is loaded without using any work loading device 1 for the transport line A.
can be delivered to the lifting transfer device 3 in an extremely short time, and it is also possible to make it unnecessary to modify the workload loading device 1 and stop the transfer line A when newly installing the transfer line B.

This invention has been explained above based on illustrated examples, but
It is also possible to use a drive means using a motor, a gear mechanism, etc. as the rotation driving means for the guide frame, and the work loading devices of both conveyance lines A and B are located adjacent to each other. In so far, the direction of extension can be selected as appropriate.

(Effects of the invention) As described above, according to this invention, especially with the work loading device for the conveyance line B,
By making it possible to directly transfer workpieces taken out of the transport route to the lifting transport equipment, it is possible to modify the work loading equipment for transport line A when constructing a new transport line B. It is also made unnecessary to stop the conveyance line A, thereby realizing a reduction in equipment cost for newly installing the conveyance line B, and at the same time, it is possible to sufficiently avoid a decrease in the operating efficiency of the conveyance line A. Moreover, in this case, by making each of the two workload loading devices function completely independently of each other, it is no longer necessary to operate one workload device in synchronization with the other workload loading device. Each work loading device and therefore each transport line A, B
The operating efficiency of the system can be greatly improved.
