It is disposed so as to be suspended between the opening 18 and the workpiece W is unloaded from the machining chamber 52a of the apparatus 50a and loaded into the machining chamber 52b of the apparatus 50b. The right transfer device 10 is disposed between the opening 18 provided on the right side surface of the device 50b and the opening 18 provided on the left side surface of the device 50c, and receives the workpiece W from the processing chamber 52b of the device 50b. It is carried out and carried into the processing chamber 52c of the apparatus 50c.

  By disposing the transfer device 10 through the opening 18 provided on the side surface of the device 50, an operator (not shown) can face the device 50 in front of the device 50. For this reason, the operator can handle the workpiece W transported by the transport apparatus 10 from the front of the apparatus 50 near the body. In addition, since there is nothing that obstructs the worker and the device 50 in front of the device 50, it is easy for the worker to check the operation of the device 50 and perform maintenance.

  The opening 18 can be provided with an open / close shutter, a warm rubber sheet, and other scattering prevention mechanisms so that the frame 11, the workpiece W, and the pallet 14a can pass therethrough. By providing the scattering prevention mechanism, it is possible to prevent the coolant, the cleaning liquid, or the chips from scattering from the inside of the apparatus 50 to the outside of the apparatus.

The configuration of the transfer apparatus 10 shown on the left side of FIG. 1 will be described mainly with reference to FIG.
The conveying device 10 includes a frame 11 that extends from the opening 18 into the device 50b, a pallet 14a that is provided so as to be movable along the frame 11 and holds the workpiece W, and a frame 11 that is rotatable. A rotation support mechanism 12 for supporting, a cam mechanism 16 which is a rotation drive device for rotating the frame 11 around the rotation shaft 12a, and a conveying means 14 for conveying the pallet 14a along the frame are provided. Yes.

The frame 11 includes a first frame 11a formed in a long plate shape, a second frame 11b (see FIG. 3) connected so as to face the first frame 11a, and the first frame 11a and the second frame. And a third frame (see FIG. 3) for connecting to 11b. The frame 11 is disposed so as to pass through the opening 18 and face the inside of the apparatus 50b (processing chamber 52b) (see FIG. 3).
In addition, when the apparatus 50b is provided with a transfer device for the work table W such as a turntable, the position where the frame 11 inside the apparatus 50b faces is changed to the loading chamber of the apparatus 50b instead of the processing chamber 52b. Yes.

The rotation support mechanism 12 includes a rotation shaft 12a disposed between the first frame 11a and the second frame 11b (see FIG. 3), a shaft support 12b fixed to the outside of the transport device 10, and It has.
The rotating shaft 12a is disposed along a horizontal direction orthogonal to the transport direction.
The rotation support mechanism 12 rotates (swings) the frame 11 up and down around the rotation shaft 12a, and the front of the conveyance direction from the state in which the frame 11 becomes horizontal (see FIG. 4B). It supports so that it can incline so that it may descend | fall (refer FIG.4 (c)).

  The shaft support 12b is fixed to a fixed object such as a device 50a in the previous process of the device 50 or a pillar in the factory. The shaft support 12b only needs to have a structure capable of supporting the rotating shaft 12a. For example, a cylinder, a through hole, a bearing, or the like that supports the rotating shaft 12a can be employed.

  In the present embodiment, the rotation shaft 12a disposed on the frame 11 as the rotation support mechanism 12 is fixed by the shaft support body 12b, and the frame 11 is rotated around the rotation shaft 12a. However, the present invention is not limited to this, and the frame 11 itself may be rotated by a cam mechanism or a link mechanism. Moreover, you may make it return to the original position of a horizontal direction using the elastic body biased in the rotation direction.

  The cam mechanism 16 includes a cam follower 16a that is an original joint provided on a slide door 51b that is a moving body of the device 50b, and a plate cam 16b that is a follower provided on the frame 11a. The frame 11 rotates in the vertical direction about the rotation shaft 12a, and is lowered downward due to the gravity acting on the frame 11, and the plate cam 16b is in contact with the lower cam follower 16a on the lower surface thereof. The lower surface of the plate cam 16b is inclined such that the front side in the transport direction (right side in the figure) is lowered and gradually positioned upward as it comes to the rear side in the transport direction (left side in the figure).

  By providing the original clause on the slide door 51b of the device 50b and providing the follower on the frame 11, the rotation of the frame 11 is interlocked with the moving operation of the slide door 51b which is the moving body of the device 50b. Does not occur. The rotation operation of the frame 11 in conjunction with the movement operation of the slide door 51b will be described later. Further, since the frame 11 is rotated by the driving force and gravity of the device 50b, no driving energy is required.

Although the cam mechanism 16 in the present embodiment is configured by providing the cam follower 16a on the slide door 51b, which is the moving body of the device 50b, and the plate cam 16b on the frame 11a, the present invention is not limited to this. A plate cam 16b may be provided on the door 51b, and a cam follower 16a may be provided on the frame 11a.
In addition, the rotation drive device is replaced with a cylinder such as an air cylinder, a hydraulic cylinder, or an electric cylinder instead of the cam mechanism 16, or an electric motor, a ball screw mechanism, a slider crank mechanism, and other conversion mechanisms that convert rotational motion into linear motion. A combination of can be used.

The conveying means 14 is a linear movement mechanism (linear motion mechanism) disposed on the frame 11.
As shown in FIG. 3, the conveying means 14 includes a pallet 14a for loading and conveying a workpiece W, rollers 14b disposed on both sides of the pallet 14a, rails 14c for guiding the rollers 14b in the conveying direction, and a conveying direction. And a rodless cylinder 14d which is a double-acting air cylinder disposed along the cylinder.

The pallet 14a includes a positioning pin (not shown) and a seating surface (not shown). The workpiece W is placed on the seating surface, and its placement position is determined by a positioning pin. Since the workpiece W is positioned by the positioning pins and is conveyed in contact with the pallet 14a only on the seating surface, even when the conveying device vibrates, the workpiece W does not slide during conveyance, and the workpiece W does not slide during conveyance. Not scratched.
A rough guide for guiding the outer shape of the workpiece W can be provided instead of the positioning pin.

A pair of rails 14c is arranged on both sides in the conveyance direction, and two rails 14c are arranged along the conveyance direction so as to be vertically aligned with the first frame 11a and two are aligned vertically with the second frame 11b.
The roller 14b is provided with two wheels on one side and front and rear in the conveying direction so as to roll between two rails 14c provided on both sides of the frame 11, respectively. As the roller 14b rolls between the two rails 14c, the pallet 14a moves in the transport direction along the rails 14c.

  As shown in FIG. 2, the rodless cylinder 14d is a drive device that reciprocates the slider 14e. The slider 14e is connected to the pallet 14a via a bracket 14f. The rod W cylinder 14d can be driven to move the workpiece W placed on the pallet 14a along the conveying direction.

  As the linear motion mechanism, a combination of a linear motion guide and a cylinder, a linear motion guide and a motor, or a combination of a pantograph mechanism and a cylinder can be used instead of the roller 14b, rail 14c, and rodless cylinder 14d.

  Moreover, it can replace with the conveyance means 14 by drive devices, such as rodless cylinder 14d, and can use a free roller conveyor. By using the free roller conveyor, the frame 11 is moved up and down by the driving device, and when the frame 11 is tilted, the workpiece W moves on the free roller conveyor by the action of gravity acting on the workpiece W. When the free roller conveyor is used, since the work W is moved only by gravity, no transfer energy is required. Moreover, there is an advantage that the structure is simplified.

  Limit switches 13a and 13b, which are first detection means, detect the position of the pallet 14a. The limit switch 13a at the moving end on the post-process side can determine whether or not the workpiece W can be unloaded from the pallet 14a to the apparatus 50b by detecting the end position of the pallet 14a (FIG. 4B). ), (C)). Further, the limit switch 13b at the moving end on the previous process side can determine whether or not the work W can be mounted on the pallet 14a by detecting the end position of the pallet 14a (FIG. 4A). reference).

  As the first detection means, a magnetic switch or a proximity switch can be used instead of the limit switch.

  The light shielding switches 19a and 19b, which are the second detection means, determine whether or not there is a workpiece W on the pallet. As the light shielding switch, a light passing type light shielding switch or a light reflection type light shielding switch can be used. The light shielding switch 19a detects the presence / absence of the work W at the end of the subsequent process (see FIGS. 4B and 4C), and the light shielding switch 19b detects the presence / absence of the work W at the end of the previous process (FIG. 4A). reference). When the pallet 14a is at the end on the post-process side, it is determined that the workpiece W can be removed by detecting the presence or absence of the workpiece W by the light shielding switch 19a. When the pallet 14a is at the end on the previous process side, the light shielding switch 19b detects the presence or absence of the workpiece W, thereby preventing the overlapping of the workpiece W, and the movement of the pallet 14a with the workpiece W remaining unloaded. Can be prevented.

  In place of the light shielding switches 19a and 19b, limit switches, dog switches, and proximity switches can be used.

  Next, the operation of the transport apparatus 10 will be described with reference to FIG. FIG. 4A shows a state in which the device 50b, which is a subsequent process of the device 50a, is in operation and the slide door 51b is closed. In this state, since the cam follower 16a disposed on the slide door 51b is hooked on the tip of the plate cam 16b, the contact point between the cam follower 16a and the plate cam 16b is closer to the lower side of the frame 11, so that the frame 11 It is held horizontally (high position). The slider of the rodless cylinder 14d moves to the end on the device 50a side in the previous process, and the pallet 14a is in the device 50a in the previous process. When the movement of the pallet 14a is completed, the dog attached to the pallet 14a hits the limit switch 13b, and the completion of the movement of the pallet 14a is detected. The workpiece W processed by the device 50a of the previous process is placed on the pallet 14a. At this time, the light shielding switch 19b detects the loading of the workpiece W.

  When the light shielding switch 19b detects the loading of the workpiece W, the conveying means 14 moves the pallet 14a by the movement of the rodless cylinder 14d. When the pallet 14a reaches the end on the post-process side, the dog of the pallet 14a hits the limit switch 13a. Then, the completion of movement of the pallet 14a is detected. Then, the work W blocks the light beam from the light blocking switch 19a and confirms the arrival of the work (see FIG. 4B).

  When the post-process device 50b finishes processing the workpiece W in the device 50b, the slide door 51b is opened as shown in FIG. Along with the opening operation of the slide door 51b, the cam follower 16a provided on the slide door 51b moves to the previous process side (left side in the figure), and the contact position between the plate cam 16b and the cam follower 16a moves from below to above with respect to the frame 11. Moving. The frame 11 falls downward with the rotating shaft 12a as a fulcrum because of the acting gravity. Since the frame 11 falls down, the pallet 14a installed on the frame 11 and the workpiece W mounted on the pallet 14a are also lowered. As a result, the space above the workpiece W in the apparatus 50b in the subsequent process is expanded, and the transfer of the workpiece W from the pallet 14a to the apparatus 50b is facilitated.

  After the workpiece W has been transferred to the subsequent device 50b, when the operator activates the device 50b, the slide door 51b of the device 50b is closed. With the closing operation of the slide door 51b, the cam follower 16a disposed on the slide door 51b moves away from the previous process side (moves in the right direction in the figure), and the contact point between the cam follower 16a and the plate cam 16b is lower when viewed from the frame 11. Move to. Then, the frame 11 is lifted around the rotation shaft 12a, and the frame 11 moves to the horizontal position (high position) when the sliding door is fully closed (see FIG. 4A).

  In the apparatus 50b, the spindle, the work table on which the work W is mounted, the rotary table on which the work W is mounted, and the like operate at various timings. Therefore, when the frame 11 of the transfer apparatus 10 rotates unexpectedly, they and the transfer apparatus. 10 may interfere and cause device damage. However, in this embodiment, since the frame 11 is rotated by the cam mechanism 16 in conjunction with the opening operation of the slide door 51b after the operation of the device 50b is completed, the moving object in the device 50b and the conveying device 10 are Interference can be prevented.

  According to the transfer apparatus 10 of the present embodiment, the frame 11 is positioned at a high horizontal position so that the frame 11 is prevented from interfering with the transfer apparatus 10 only when the apparatus 50b is in operation. Since the frame 11 rotates downward during transfer and a space above the workpiece W mounted on the frame 11 is secured widely, the apparatus height of the apparatus 50b can be kept low. When the device 50 is kept lower than the eye level of the operator, the operator can see the entire line.

[Modification]
In the above embodiment, the cam mechanism 16 moved the frame 11 up and down according to the movement (moving in the direction along the conveying direction) of the slide door 51b of the apparatus 50b in the subsequent process. However, the present invention is not limited to this, and may be interlocked with an operation in which the slide table 62, which is a moving body of the post-process device 60b, moves in the front-rear direction (direction perpendicular to the transport direction).

  Hereinafter, in accordance with FIGS. 5 and 6, when the slide table 62 of the post-process device 60 b moves in the front-rear direction (direction orthogonal to the transport direction) in the processing line 200, the cam follower 26 a is provided on the slide table 62, and the frame 11 shows a transfer device 20 in a modification in which a plate cam 26b is provided. In addition, about the structure similar to the above-mentioned embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The post-process device 60b includes a slide table 62 that moves in the front-rear direction, and the slide table 62 is provided with a cam follower 26a that is an original node. The frame 11 of the transport device 20 is provided with a plate cam 26b that is a follower. The frame 11 rotates around the rotation shaft 12a. The frame 11 is supported by its gravity in contact with a cam follower 26a in which a plate cam 26b is disposed below.

The cam follower 26a and the plate cam 26b constitute a cam mechanism 26 that is a rotational drive device. The bottom surface of the plate cam 26b has an inclination that warps in front of the device 60b.
When the device 60b is machining the workpiece W on the slide table 62, the slide table 62 is lowered to the rear of the device 60b (FIGS. 5A and 6A). At this time, the contact point between the cam follower 26a and the plate cam 26b is lowered downward as viewed from the frame 11, and the frame 11 is held at a horizontal position (high position). Since the frame 11 is held at a high position, the operation of the device 60b is not hindered.

  The slide table 62 moves forward when the device 60b finishes machining and replaces the workpiece W. Then, the contact point between the cam follower 26a and the plate cam 26b moves slightly upward as viewed from the frame 11, and the frame 11 falls down about the rotation shaft 12a (FIGS. 5B and 6B). At this time, since the space above the workpiece W placed on the pallet 14a above the frame 11 is widened, the workpiece W can be easily replaced.

  The cam mechanism 26 in the present embodiment is configured by providing the cam follower 26a on the slide table 62, which is the moving body of the device 60b, and the plate cam 26b on the frame 11a. However, the present invention is not limited to this. A plate cam 26b may be provided on the table 62, and a cam follower 26a may be provided on the frame 11a.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be implemented with appropriate modifications.
For example, in the present embodiment, the slide door 51b, which is a moving body, is applied to the slide door 51b that moves in the direction along the transport direction, but is not limited to this, and is similar to the slide table 62 shown as a modification. It is also possible to apply a sliding door that moves in the front-rear direction orthogonal to the transport direction.

  In the present modification, the slide table 62 that is a moving body is one that moves in a direction (front-rear direction) orthogonal to the transport direction. However, the present invention is not limited to this and is shown as the present embodiment. It is also possible to apply a slide table 62 that is configured similarly to the slide door 51b and moves in a direction along the transport direction.

  Further, instead of the slide table 62, a lift and carry device, a turntable, or other transfer device in the device can be applied as the moving body. The cam mechanism can be appropriately designed according to the moving form of the moving body.
