2. Description of the Related Art In a production facility for automobile parts, a production facility for electric products, etc., a work or a pallet on which the work is placed is conveyed to a plurality of processing stations by a conveyor line such as an electric conveyor or a free flow line. They were sequentially transferred, and various treatments were performed at each treatment station. For example, as shown in FIG. 7, a plurality of processing apparatuses that perform various processes, that is, processing stations A to F and processing units A1 to F1 are installed along a transfer line 1 that transfers a work W,
Further, in order to draw the work W into the plurality of processing stations A to F, a plurality of drawing lines 1a to 1f branched from the carrying line 1 are provided.

The work W transported from the upstream side of the transport line 1 is first carried into the processing station A via the pull-in line 1a, positioned at that location, and assembled by the assembly unit A1, for example. After that, it is carried into the next processing station B and is repositioned there, and another part is assembled to the other position of the work W by the assembly unit B1, and subsequently, the processing station C is installed. ~
The work W is sequentially loaded into the F and positioned at each place, and various processing such as assembling, processing, or inspecting other parts is further performed by the processing units C1 to F1.

[0004]

By the way, in the production facility equipped with the above-mentioned processing device, when the assembly position or the processing position is different when assembling or processing the parts to the work W, a plurality of corresponding units are installed. The processing stations A to F and the processing units A1 to F1 are required, and the carry-in lines 1a to 1f for carrying in the work W have to be installed corresponding to the respective processing stations. Therefore, a wide space is required for arranging these processing devices, and time is required for the setup for transferring the work W to each of the processing stations A to F and setting the work W. It has been desired to improve productivity by shortening the time required for such purposes. Further, when the processing unit is large, it is difficult to move the processing unit to perform various kinds of processing on the work W.

The present invention has been made in view of the above problems, and an object thereof is to perform various kinds of processing on a work, while reducing the number of processing stations as much as possible. Another object of the present invention is to provide a work processing apparatus capable of simplifying production equipment, improving productivity, saving space, etc. by shortening the time required for transfer to the next step.

A work processing apparatus of the present invention is a work processing apparatus for performing various kinds of processing on a work conveyed by a conveyance line, and is a separation for vertically separating the work from the conveyance line. Means, a positioning and supporting means for carrying the workpiece simultaneously with the separation by the separating means and moving it to a desired position for positioning, and a processing unit for performing a predetermined process on the workpiece carried by the positioning and supporting means. It is characterized by having.

According to this construction, the work supported on the transfer line is vertically separated from the transfer line by the separating means and is carried by the positioning supporting means at the same time. Then, the positioning supporting means positions the work at a desired position, and the processing unit performs a predetermined process on the positioned work. After that, the processed work is again supported by the transfer line by the reverse operation of the separating means and is transferred to the downstream side.

As described above, since the processing for the work is performed in the vicinity of the transfer line (within a range where the positioning is performed without largely deviating from the transfer line), a processing station or the like is provided at a position distant from the transfer line. There is no need to save space. Further, the time required for the transfer process can be shortened by that much, and the productivity is improved. Further, since the work is carried and positioned by the positioning and carrying means, it is possible to carry out a process to which a high load is applied or a process which requires highly accurate positioning.

In the above structure, the separating means forms a part of the conveying line and independently supports the movable conveying line so as to be movable in the vertical direction, and the movable conveying line can be moved up and down and lowered to separate the work. It is possible to employ a configuration having a lifting unit that causes the lifting unit. According to this configuration, when the work carried by the carrying line reaches the movable carrying line, the work is carried by the positioning carrying means and separated from the movable carrying line when the moving unit is lowered by the elevating unit. . In this way, the separating means can be configured with a simple structure, and the work can be easily separated.

In the above structure, the positioning support means is
It is possible to employ a configuration having a carrying table that carries the work that has been separated by the separating means and that is moved to a desired position in the horizontal plane, and drive means that moves and positions the supporting table. According to this structure, the work separated by the separating means is carried on the carrying table, and the carrying table moves the carrying table to a desired position in the horizontal plane (for example, linear movement or rotational movement) to move the work. Position. Thus, the work can be supported and positioned with a simple structure.

In the above construction, the carrying table carries the work and is moved in the carrying direction of the movable carrying line, and the carrying table carries the upper carrying table and is moved in a direction orthogonal to the carrying direction. A configuration having a side supporting table can be adopted. According to this structure, the work detached by the detaching means is carried by the upper carrying table, and the upper carrying table is linearly moved in the carrying direction in the horizontal plane by the driving means.
Further, the lower carrying table is linearly moved by the driving means together with the upper carrying table in a direction orthogonal to the carrying direction in the horizontal plane to position the work. That is,
The XY table positions the work at a desired position in the horizontal plane. Thus, the work can be supported and positioned with a simple structure.

In the above structure, the lower carrying table is
It is possible to adopt a configuration having a carrying section that carries the movable transfer line separated from the work. According to this configuration,
The movable transfer line separated from the work is carried by the lower carrying table via the carrying part. Thereby, the upper carrying table moves in the carrying direction independently of the movable carrying line, while the lower carrying table moves the upper carrying table and the movable carrying line integrally in the direction orthogonal to the carrying direction. As a result, reliable movement for positioning can be performed with a simple structure.

In the above structure, the processing unit may be composed of a plurality of processing units arranged above the positioning means. According to this configuration, a plurality of processing can be performed on the work by positioning the work in association with the plurality of processing units. That is, since a plurality of treatments can be performed in the same treatment station, the time required for the transfer process can be omitted as compared with the case where treatments are performed in a plurality of treatment stations installed in different places as in the past. Further, since it is not necessary to install a plurality of processing stations, it is possible to save space.

Assembly unit 5 as a processing unit
0 has the 1st press fit unit 51 and the 2nd press fit unit 52, as shown in FIG. The first press-fitting unit 51 and the second press-fitting unit 52 press-fit an oil seal as a component, that is, a large-diameter oil seal and a small-diameter oil seal into a bearing hole of an engine or a transmission, respectively. The press-fitting shaft 51a, which is driven to extend and contract in the vertical direction by the
52a.

As shown in FIG. 1, the first press-fitting unit 51 and the second press-fitting unit 52 are arranged in a horizontal direction (conveying direction L) with respect to a frame 82 installed on a side wall frame 81.
It is movably supported by 1). Therefore, the first press-fitting unit 51 or the second press-fitting unit 52 is appropriately selected according to the oil seal to be press-fitted, and is moved so as to face the desired position of the work W.

The processing unit (first press-fitting unit 51
Alternatively, the second press-fitting unit 52) may be fixed to the substantially central portion of the frame 82, and the work W may be positioned only by the XY table 40. In this case, since the processing unit is fixed, a relatively large heavy object can be adopted as the processing unit.

As shown in FIGS. 1, 2 and 4, the component supply unit 60 is supported by the side wall frame 81 and reciprocates in the front-rear direction (direction L2 orthogonal to the transport direction L1), and the front-rear slider 61, The first slider 62 and the second slider 63 are supported by the front and rear sliders 61 and reciprocate in the transport direction L1. The first slider 62 and the second slider 63 each have a first chuck 62a that is movable in the vertical direction and is capable of gripping a large-diameter oil seal, and a second chuck 63a that is capable of gripping a small-diameter oil seal.

As shown in FIGS. 1 and 4, the magazine 70 is arranged behind the component supply unit 60 and has a first magazine 71 for storing a large diameter oil seal and a second magazine 71 for storing a small diameter oil seal. And a magazine 72.

Therefore, when the front-rear slider 61 retracts and reaches the upper side of the magazine 70, the first chuck 62a takes out a large-diameter oil seal from the first magazine 72,
Further, the second chuck 63a takes out the small-diameter oil seal from the second magazine 72. Then, the front-back slider 61 moves to the front (near the lower part of the assembly unit 60). Subsequently, when the first press-fitting unit 51 is selected, the first slider 62 moves to the corresponding position, the first chuck 62a descends, and the large-diameter oil seal is positioned at the press-fitting position of the work W. , When the second press-fitting unit 52 is selected, the second slider 63 moves to the corresponding position,
The second chuck 63a is lowered to position the small-diameter oil seal at the press-fitting position of the work W.

Next, the operation of this work processing apparatus will be described. In order to automatically perform the entire operation, the control system includes a ROM that stores various control data (recipe) and a CP that controls various operations.
Control unit (microcomputer) including U, work W
Alternatively, a sensor or the like for detecting the pallet P is provided. In addition, the start and end of various operations described below are
This is performed based on the detection signal of the sensor and the control signal output from the control unit based on this detection signal.

First, the work W (pallet P) conveyed from the conveyance line 10 reaches the movable conveyance line 20 and is stopped by the stopper as shown in FIGS. 2 and 3. Then, the elevating unit 30 operates to lower the movable transfer line 20. That is, when the pallet P is carried on the upper carrying table 41 while being positioned by the pins 41a as the movable transfer line 20 descends following the lowering operation of the lifting rod 31a driven by the hydraulic cylinder 31, As shown in FIGS. 5 and 6, the roller 21 separates from the lower surface of the pallet P. As a result, the work W is separated from the movable transfer line 20 in the vertical direction. Furthermore, the lifting rod 3
When 1a descends, the movable transfer line 20 moves to the carrying section 42a.
And is carried on the lower carrying table 42. After that, the elevating rod 31 a stops when the support arm 32 separates from the support column 23.

Subsequently, the servo motors 44a and 45a are appropriately rotated to move the upper carrying table 41 to a predetermined position in the carrying direction L1 and the lower carrying table 42 is carried out in a predetermined direction L2 orthogonal to the carrying direction L1. The work W is moved to the position and the work W is positioned at a predetermined position in the horizontal plane. As described above, since the work W is two-dimensionally positioned in the horizontal plane by the upper carrying table 41 and the lower carrying table 42, the work W is positioned with high accuracy with respect to the built-in unit 50 arranged above. can do.

Then, the first press-fitting unit 51 and the first slider 62 are operated (and, if necessary, horizontally moved in a horizontal plane) to hold the large-diameter oil seal.
The chuck 62a descends to position the oil seal at a predetermined position on the work W, and the press-fitting shaft 51a descends to press-fit the oil seal. Then, the press-fitting shaft 51a and the first chuck 62a move up.

Subsequently, the servo motors 44a and 45a are appropriately rotated to move the upper carrying table 41 to the carrying direction L.
1, the lower carrying table 42 is moved to a predetermined position in the direction L2 orthogonal to the transport direction L1, and the work W is moved to another position in the horizontal plane (a position where a small-diameter oil seal is press-fitted). ) Position.

Then, the second press-fitting unit 52 and the second slider 63 are operated (and, if necessary, horizontally moved in a horizontal plane) to hold the second diameter oil seal.
The chuck 63a descends to position the oil seal at a predetermined position on the work W, and the press-fitting shaft 52a descends to press-fit the oil seal. Then, the press-fitting shaft 52a and the second chuck 63a move up.

In this way, when performing the press-fitting process, the work W is loaded on the upper carrying table 41 and the lower carrying tail portion 42.
Since the work W is supported by the XY table 40 made of, for example, even if the press-fitting process involves a relatively large load, the work W is firmly supported and the press-fitting process can be reliably performed. Moreover, since two processes can be performed in one station, the processing time can be shortened and space can be saved as compared with the conventional case.

Here, when the same oil seal is press-fitted to different positions of the work W, only one of the first press-fitting unit 51 and the first slider 62 or the second press-fitting unit 52 and the second slider 63 is repeatedly operated. At the same time, this can be dealt with by moving the XY table 40 and appropriately positioning the work W.

Thereafter, in particular, the servo motor 45a is appropriately rotated to move the lower carrying table 42, and the movable carrier line 20 is positioned at the first position aligned with the carrier line 10 as shown in FIG. Then, as the lifting rod 31a is moved up by the driving of the hydraulic cylinder 31, the support arm 32 comes into contact with the support column 23 to push up the movable transfer line 20 and raise it to the same height as the transfer line 10. The driving of the lifting unit 30 is stopped.

The pallet P is carried by the rollers 21 and separated from the upper carrying table 41 by the rise of the movable carrying line 20, and is positioned at the initial position (height). Then, the roller 21 is rotated at the same time as the stopper is retracted (immersed), and the work W and the pallet P are unloaded to the downstream transfer line 10.

Further, in parallel with the above-described series of returning and carrying-out operations, the parts supply unit 60 stands by in a state where parts can be supplied for the next press-fitting process. That is, when the front / rear slider 61 retracts and the first chuck 62a and the second chuck 63a take out the next oil seal from the magazines 71 and 72, the front / rear slider 61 moves forward again and
The slider 62 and the second slider 62 are positioned near the lower side of the first press-fitting unit 51 and the second press-fitting unit 52 and stand by. After that, the above series of operations are repeatedly and automatically performed.

In the operation described above, the first chuck 62a and the second chuck 63 holding the oil seal.
Although a is shown as being driven so as to descend to the press-fitting position of the work W, as another operation mode, the first press-fitting unit 51 and the second press-fitting unit 52 are provided with a function of holding an oil seal, The first chuck 62a and the second chuck 63a holding the seals approach the first press-fitting unit 51 and the second press-fitting unit 52 from below, and deliver the oil seal to the first press-fitting unit 51 and the second press-fitting unit 52, and thereafter. , And may be driven so as to descend and retract to a predetermined standby position.

In the above-described embodiment, the movable transfer line 20 is lowered by the elevating unit 30 and the XY table 40 is shown as the separating means and the positioning carrying means, but the present invention is not limited to this, and the transfer line 10 is not limited thereto. By adopting only the above, the pallet P that has been conveyed to a predetermined position is lifted from the lower side by a rotatable carrying table to be removed, and the carrying table is rotated to a desired angular position to move the work W to a predetermined position in a horizontal plane. It may be possible to adopt a configuration in which it is positioned at the position. In this case, since the carrying table also serves as the separating means and the positioning carrying means, the work W can be appropriately positioned and various processing can be performed without largely deviating from the transfer line 10, and the same effect as described above can be obtained. To be
