Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for cutting and drilling a long workpiece. [0002] For example, in the manufacture of screen doors and sash frames,
The cutting device cuts the long profile into a predetermined length and processes it into a frame. The cutting device places the long profile on the transport path (mounting section) and places it on the transport path. The holding unit grips one end of a certain long material, pushes it to the cutting unit, and cuts it by the cutting unit every time a predetermined length is fed. [0003] The conventional cutting device is provided with a conveyor for supplying the next profile to the transport path beside the transport path. After the transport of the profile on the transport path is completed, the next profile is transported by the conveyor. The material is transported on the transport path, and the profile on the conveyor is moved to the transport path. [0004] However, in a conventional processing apparatus which supplies a profile to the transport path by a conveyor from one side (lateral side) of the transport path, the profile carried by the conveyor is transported to the transport path. When the profile is moved, the position of the profile is easily shifted each time the profile is moved, and it is difficult to position the profile at a predetermined position. For this reason, there is a problem that it is difficult for the holding unit to hold the profile. SUMMARY OF THE INVENTION It is an object of the present invention to provide a processing apparatus which can easily position a workpiece placed on a mounting portion. According to a first aspect of the present invention, there is provided a mounting portion on which a long workpiece is placed, and a processing portion located at one end of the workpiece in the longitudinal direction. Means, moving means for moving the workpiece on the mounting portion to the processing means, and a plurality of arms for receiving the workpiece above the mounting portion,
Each arm is arranged in the longitudinal direction of the workpiece and each arm is interlocked, each arm is a standby position located above the mounting portion, and a position lower than the upper surface of the mounting portion from the standby position,
It is characterized in that it is located at a position avoiding the workpiece when ascending from the descending position. According to the first aspect of the present invention, the arm places the workpiece at the standby position, descends while the workpiece is mounted at the standby position, and moves down from the upper surface of the mounting portion. Located below. During the lowering of the arm, the workpiece to be received by the arm is directly transferred from above to the upper surface of the mounting portion. Therefore, since the workpiece can be placed on the placement section while being placed on the arm, the position previously determined when placing the workpiece on the arm is displaced by the placement section. Because it can prevent deviation from the track,
It is easy to position the workpiece on the mounting portion. [0008] Further, since a standby space for the workpiece to be supplied to the mounting portion is above the mounting portion and the workpiece is not made to wait on the lateral side of the mounting portion as in the related art, the device has a small space. Since the space occupied is small and a conveyor is not used on the side of the mounting portion, the entire apparatus can be downsized. Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. As shown in FIG. 1, a processing apparatus 1 according to the present embodiment cuts a profile (member to be processed) at predetermined lengths, and one cutting machine (processing means) 3 includes four Are cut at the same time. This processing apparatus 1 cuts a profile into two kinds of dimensions having different lengths of a vertical frame and a horizontal frame constituting a screen frame. The processing apparatus 1 includes a transport unit (mounting unit) 6 in which two transport paths, that is, a first transport path 5 and a second transport path 7 are arranged side by side and in parallel. In this case, since the profile 4 is cut to the size for the vertical frame and the second transfer path 7 is cut to the size for the horizontal frame, the cut length differs in each transfer path. Therefore, the first transport path 5 and the second transport path 7 have different transport amounts of the profile 4 transported to the cutting machine 3 from cutting to the next cutting. It should be noted that any of the first and second transport paths 5 and 7 may be used for a vertical frame or a horizontal frame, and any of the first and second transport paths 5 and 7 may be used for cutting a profile material with a long dimension. Good. The first and second transport paths 5 and 7 are
The section 4 is simultaneously conveyed to the cutting machine 3. The first and second conveying paths 5 and 7 are provided with a plurality of rollers 9 for mounting the section 4 and a plurality of rollers 9 on the plurality of rollers. Plural shaped members 4
Holding units 11a and 11b that travel while holding the unit are provided. Each roller 9 is arranged in the width direction of the transport unit 6 and is shared by the first and second transport paths 5 and 7. Although not shown, the roller 9 is provided with a sensor for detecting the presence or absence of the profile 4 on each of the transport paths 5 and 7, and the sensor for detecting the presence or absence of the profile 4 is provided by the cutting machine 3. Is also provided in front of. A guide rail 1 for guiding the traveling of the clamping units 11a, 11b is provided on the side of the first and second transport paths 5, 7.
3a and 13b are provided. In the transport unit 6, a plurality of arms 15 are located at positions where the first and second transport paths 5 and 7 are adjacent to each other.
Are arranged in two rows along the longitudinal direction of the profile. The arm 15 of the first arm row 16a supplies the next profile to the first transport path 5, and the arm 15 of the second arm row 16b supplies the next profile to the second transport path 7. Each arm 15 is driven separately for each row in the first arm row 16a and the second arm row 16b, but the arms 15 in the same row are interlocked. The arms 15 in the same row may be driven with a slight time difference other than when the arms 15 are driven simultaneously. The drive of each arm 15 is controlled by a drive unit 17 below the first and second transport paths 5 and 7 so that the arm 15 moves up and down and turns.
The specific driving of No. 5 will be described later. As shown in an enlarged view in FIG. 2, each arm 15 has an inclined surface 23 on the mounting surface side of the profile 4 so as to descend from both ends to a substantially central protrusion (positioning portion) 21. Are formed, and the profile 4 placed on both sides of the projection 21 hits the projection 21 located substantially at the center, and is located at the positioning position. By providing such an inclined surface 23, the profile 4 placed on the arm 15 is
Along with the protruding portion 21 by its own weight, and can be automatically positioned. The arm 15 is fixed to the top of a shaft 25, and the shaft 25 moves up and down by an air cylinder. As shown in FIG. 3, the first and second arm rows 16a, 16b
Each time, the shaft 25 of each arm 15 moves synchronously by a pinion gear 29 connected to the lower end side of each arm shaft 25. A gear 31 is provided at the lower end of the shaft 25.
And a worm gear 33 meshing with the gear 31. The worm gear 33 is connected to the arm shafts 25 of the respective arm rows 16a and 16b, and the respective arm shafts 25 rotate in synchronization. . One holding unit 11a is engaged with a first guide rail 13a on the first transfer path 5 side of the transfer unit 6, and runs along the first guide rail 13a.
The other holding unit 11b is engaged with the first guide rail 13a outside the second transport path, and travels along the first guide rail 13a. As shown in FIGS. 3 and 4,
Each of the holding units 11a and 11b travels with the holding portion 35 holding the end of the profile and pressing the profile. As shown in FIG. 4, the holding units 11 a and 11 b include a cylinder 39 and a claw portion 4 opened by driving the cylinder 39.
1, the claw 41 is opened and pushed toward the end of the profile 4, and the hollow of the profile 4 is inserted into the support portion 43. After the insertion,
When the end of the profile 4 hits the detecting portion 45, the cylinder 39 is operated to close and hold the claw portion 41.
The holding units 11a and 11b move at high speed to a position where they are not detected due to the short length of the profile 4 by the sensor for detecting the presence or absence of the profile, and at low speed near the detection position. 4 so as to move efficiently according to the length of the profile 4 placed thereon. Next, the operation of the present embodiment will be described. As shown in FIG. 1, in the transport unit 6, each of the first transport path 5 and the second transport path 7 is provided with a total of four profiles 4 each of which is two. The rear end is held by the holding units 11a and 11b. The holding units 11 a and 11 b travel toward the cutting machine 3 and transport the profile to the cutting machine 3. When a sensor located in front of the cutting machine 3 with respect to the conveying direction detects the tip of the profile 4 conveyed to the cutting machine 3, after the detection, the clamping unit 11a (for example, a distance of 300 mm) is detected. Or 11b) is profile 4
To stop at that position, and the cutting machine 3 cuts and removes the end (ear) of the profile 4. After cutting off the ears, the holding unit 11a moves by a predetermined dimension, and the profile is cut for each predetermined dimension. Then, as the cutting proceeds, the remaining dimension of the profile 4 decreases, and if it cannot be cut any further, the profile 4
Since the sensor for detecting the presence or absence of the presence of the shape member detects that there is no profile at a predetermined position, the cutting is terminated. When the cutting is completed, the clamping unit opens the claw 41 and retreats in front of the cutting machine 3.
At this time, the remaining part of the profile 4 is located in front of the
(Or 7), but the rest of the profile 4 falls from an opening below the transport path 5 (or 7). The cutting machine 3 simultaneously cuts a total of four profiles 4 in the first and second transport paths 5 and 7. Is longer than the cutting dimension of the profile in the second transport path 7, and the profile of the first transport path 5 advances faster by the next cutting. Accordingly, since the transport of the profile 4 is completed earlier in the profile 4 of the first transport path 5 than in the profile 4 of the second transport path 7, the supply of the profile 4 is more efficient in the first transport path 5. Frequent. On the other hand, the first transport path 5 and the second transport path 7 are provided with arms 15 which stand by above each other. When the arm 15 is in the standby position, as shown in FIG. It is located in a direction that is orthogonal to. When the arm 15 is at the standby position, the next section 4 is placed on the arm. The placement of the profile, for example,
An operator carries the profile from the guide rail 13b side of the second transport path 7 and puts it on the arm.
5, it can jump over the second transport path 7 and can be easily loaded. Therefore, the next profile 4 can be supplied from one side of the transport unit 6 to the arms 15 of the first and second transport paths 5 and 7, and the supply of the profile is easy. In addition, the shape material storage place may be one place on one side of the transport unit 6. The profile 4 received by the arm 15 is waiting above the first and second transport paths 5 and 7. For example, when the transport of the profile 4 in the first transport path 5 is completed, the workpiece 4 is pinched. The unit 11a moves away from the cutter 3 and returns to the initial position at the end of the first transport path 5. Subsequently, when the operator operates the control panel to supply the next profile 4 to the first transport path 5, the arm 15 is driven as follows. Incidentally, Yorazu the operator's operation, clamping units 11a, when 11b is returned to the initial position, automatically be one that drives the arm so as to supply the next profile detects this Is also good. As shown in FIG. 2, the arm 15 descends from the standby position (first position) A to the second position B with the profile loaded thereon. Since the second position B is below the roller 9 of the transport unit 6, the profile placed on the arm 15 is received by the roller 9 just before the second position B as it is. Next, the arm 15 turns about 90 degrees from the second position B toward the outside of the transport path and is located at the third position C on the lateral side of the transport path. At the third position C, the arm 15 is a position to avoid the next section 4 placed on the first transport path 5 when the arm 15 moves up next. It rises as it is from the third position C and is located at the fourth position D above the first transport path 5. Therefore, when the arm 15 is lifted, it can be lifted as it is, avoiding the next section set in the first transport path 5. Next, the fourth
From the position D, the arm 15 turns by 90 degrees, returns to the standby position A orthogonal to the conveyance path, and receives the next profile. The arm 15 repeats the above-described driving to sequentially supply the next profile. Note that the arm 15 is also provided in the second conveyance path 7.
Drives similarly. The profile 4 supplied to the conveying paths 5 and 7 is held by a side clamp unit 47 (see FIG. 1) so as not to move, and then the clamping units 11a and 11b hold the ends of the profile. Pinch. In addition, the clamping units 11a, 11
b, the side clamp unit 4
7 is released. As described above, in the present embodiment, the next section 4 is made to stand by on the first conveying path 5 and the second conveying path 7, and is made to stand by above each conveying path 5, 7. Since the next profile 4 is lowered and transferred to the respective transport paths 5 and 7 as it is, positioning of the profile placed on each transport path can be easily performed. Further, since the profile 4 stands by above the transport paths 5 and 7, the space occupied by the processing apparatus 1 can be reduced, and a compact apparatus can be provided. In addition, the configuration is simple because only the arm 15 is raised and turned. Further, the first transport path 5 and the second transport path 7 are
Since the respective arm rows 16a and 16b are driven independently, the cutting length of the profile 4 in the first transport path 5 and the second transport path 7
When the cut length of the profile 4 is different, the supply frequency and timing of the next profile are different, but the next profile 4 is supplied to the first transport path 5 and the second transport path 7 independently. Since it is possible, the profile can be cut continuously, and the workability is good. Further, in the present embodiment, of the four frame members constituting the frame of the screen door, two of the four frame materials supplied from the first transport path 5 are used.
The two profile members are cut into two horizontal frame members, and at the same time, the two profile members supplied from the second transport path 7 are cut into two vertical frame members. A set of book frame materials is cut simultaneously. The four frame members cut by the cutting machine 3 are transported as a set to the next frame member processing step, assembling step, and the like. Therefore, the process from the cutting to the final product can be transferred to the next process in a set of four wires, and there is no need to sort or combine the frame members after the cutting, and the screen door can be easily manufactured. The present invention is not limited to the above embodiment,
Various modifications can be made without departing from the spirit of the present invention. For example, the processing apparatus 1 includes a
Not only those that supply the workpieces but also those that supply the workpieces such as the shape members and the plate members to the processing machines such as the hole punching machine and the cutting machine. Further, the number of the transport paths 5 and 7 is not limited to being provided in parallel, and may be only one. The processing machine 3 is not limited to being provided at one end side of the transport unit 6 but may be located in the transport unit 6 in the transport direction of the profile 4. The turning of the arm 15 may be either right turning or left turning. The arm is not limited to turning, but may be protruded so as to intersect the conveying path side by linear movement by a cylinder, It may be one that withdraws from. Further, the arm 15 may be configured to fall down when ascending from a horizontal direction intersecting the transport path,
It may extend at the standby position and contract when rising from the descending position to avoid the profile placed on the transport paths 5 and 7. According to the first aspect of the present invention, the arm on which the member to be processed is placed is lowered while being placed on the arm, and the next member to be lowered is moved to the position of the mounting portion. Since the workpiece can be placed on the placement surface from above, positioning of the workpiece to be placed on the placement section is easy. Further, since the member to be processed waits above the mounting portion, the occupied space can be reduced, and the apparatus can be downsized.
