The V block 52 on the separator side is normally in a lowered state, and after the shoe body S separated and aligned is moved, and the rod-like support penetrates all (plural pieces), the cylinder 54 is completed. The rod-shaped support body is supported by two pin blocks 51 and 52 at both ends thereof.
<Step of Hanging Rod-Shaped Supporter K Supporting Shoe Body S (Work Object) in Multiple Separately Aligned States on Hanger H>

Second traverse section 6

The 2nd traverse part 6 hangs the rod-shaped support body which supports the shoe main body S (work object) of the separated alignment state with the lifter part 7 demonstrated below. To form a process.

The second traverse portion 6 has a lifter portion 7 having a rod-like supporter portion 5 on the rail L of the transfer line of the hanger H shown in FIG. 1st cylinder 61 for a second traverse between the position L1 which receives (), and the position L2 which hangs the rod-shaped support body which provided the shoe main body S in the hanger H, and The second cylinder 62 for the second traverse functions to move horizontally along the linear guide 63.

Moreover, the 2nd traverse part 6 is arrange | positioned horizontally in the direction orthogonal to the shoe guide rail 37, and uses the 2nd 1st and 2nd cylinders 61 and 62 as illustrated in FIG. The use of two cylinders, as shown in Fig. 5, because the hanger from which the empty bar-shaped support was separated moves toward the position L2 of the hanger conveying line L, This is to set the intermediate stop position (T) (see Fig. 5) to avoid interference. If a sensor or the like is installed to confirm the intermediate stop position (T), the function of the traverse unit 6 can be fulfilled by one cylinder. Can be.

Lifter part (7)

The lifter portion 7 is a height position for setting the hanger H at a position where the rod-like supporter portion 5 can pass the rod-shaped support body through the plurality of shoe bodies S. (Or the linear guide 73 in the vertical direction by the first cylinder 71 for the lifter and the second cylinder 72 for the lifter up to the position L1 for receiving the empty rod-shaped support from the hanger H); Performs a function to move along.

As illustrated in Fig. 5, the lifter portion 7 uses two cylinders 71 and 72. In the case of using two cylinders, as shown in Fig. 5, an empty bar-shaped support is separated. In order to set the intermediate stop position M (refer FIG. 5) for avoiding interference with the hanger H because the hanger H which has been moved is moving toward the position L2 of the hanger conveyance line L. FIG. to be. Also in this case, by providing the sensor etc. which can confirm the intermediate stop position M, the function of the lifter part 7 can be fulfilled with one cylinder.

In addition, although not shown in FIG. 4 to FIG. 6 for explaining the above-mentioned embodiment, a servo motor and a ball screw instead of the 1st traverse cylinder 41 of the 1st traverse part 4 are shown. Each shoe body separated and sent out one by one from the shutter 2 by using a pair of two guide plates 33 and 34 of the separator 31 so as to correspond to one shoe body. It is also possible to pass S through the rod-shaped support one by one. In other words, the separator 31 is provided with a set of guide plates 33 and 34 so that one shoe body is taken at a time. Do it. Then, the first traverse portion 4 moves forward and backward so that the shoe main body S passes through the rod-shaped support K one by one. According to this structure, even if it is in the manufacturing line in which shoes of different shape, such as shoe width difference, are mixed, it becomes possible to respond.

In addition, the method of driving the second traverse portion 6 and the lifter portion 7 is controlled by the NC using a servo motor and a ball screw, so that the positions of the holes of the shoe main body S are different. In this case, it is possible to cope with a shoe. In this case, it is preferable to process the groove | channel N corresponding to the shoe main body of other models in advance in the rod-shaped support body in correspondence with the manufacturing line of a mixed product of various types.

Next, the shoe main body S supplied from the previous process is transferred to the next step through the automatic hooking device 100 of the shoe main body S formed from the respective parts having the respective functions described above. The operation on the hanger (H) to be described is described below in two parts.

a. First half part: A plurality of shoe bodies S closely contacted and arranged on the chute 11 by the stoppers 21 and 22 of the shutter part 2 are carried out one by one, and the separator 31 of the separator part 3 is carried out. Until the operation of separating and aligning the plurality of shoe bodies 1 carried out on the guide rails 37).

b. The latter half part: An empty rod-shaped support body is received from a hanger H, and the shoe | mouth main body S is supported through the rod-shaped support body, and it hangs to the hanger H.

<Description of overall operation>

First, the plurality of shoe bodies S closely aligned with the storage unit 1 are carried out one by one by the stoppers 21 and 22 of the shutter unit 2 sequentially.

Then, one shoe body S to be carried out slides on the chute 11 of the descending slope by its own weight, and is moved onto the shoe guide rail 37 of the separator portion 3, and the corresponding rail 37 The web of the shoe main body S comes into contact with the stopper 32 at the tip (right side of FIG. 4) of the head) and stops. After checking the passage of the shoe main body S by a sensor or the like, the separator 31 Is ascended by the separator ascending and descending cylinder 35, and in this state, the rod of the separator forward and retreat cylinder 36 is advanced toward the stopper 32, and the gap C _w of the guide plates 33 and 34 is When it is located in the web of the shoe main body S, the separator 31 descends. Then, the web of each shoe S enters the gap C _w of the separator 31. The rod of cylinder 36 retreats so that one of the shoe bodies S is aligned on the shoe guide rail 37.

Subsequently, when each of the second and subsequent shoe bodies S is taken out and supplied one by one from the shutter unit 2 and contacts the stopper 32 of the separator 31, the second and subsequent shoes are operated by the same operation as described above. The main body S moves to the alignment position in order. Thus, the separator 31 repeats the cycle operation | movement of up-entry (right movement) -down-retraction (left movement) several times by the action of the two cylinders 35 and 36, and the several shoe main body S is repeated. The process of separating and aligning on the shoe guide rail 37 is completed.

<Description of operation of the latter part>

It is performed in parallel with the operation of the first half of the above, and the rod-like support K is received from the hanger H, and the rod-like support for supporting the shoe main body S is hanged up to the hanger H. The operation will be described with reference to FIG. 5.

First, in the original position I of the operation, the horizontal position is at position L1 on the hanger conveying line rail in Fig. 5, while the vertical position is at intermediate stop position M. That is, the second traverse portion 6 The rods of the first and second cylinders 61 and 62 of both sides are in a retracted state, and the rod of any one cylinder 71 of the lifter portion 7 is in an advanced state, and the other The rod of the cylinder 72 is in a retracted state. In this state, the hook blocks 51 and 52 of the rod-shaped support supporter 5 have a hanger H on which an empty rod-shaped support is held. It operates in the following order (i) to (viii) at the point located upward.

(i) The lifter portion 7 moves to the rising end by the retraction of the rod of the cylinder 71 that has been advanced.

By this operation, the two shock blocks 51 and 52 of the supporter part 5 of the rod-shaped support body are lifted to a position slightly higher than the hook part of the hanger H, so that the hanger H The rod-like support that was supported is moved in a state where both sides are supported by the V blocks 51 and 52.

(ii) In this state, the rod of the first cylinder 61 advances, and the V blocks 51 and 52 move in the direction of the arrow (right direction) in Fig. 5 to the intermediate stop position T.

(iii) At this intermediate stop position T, the rod of the cylinder 71 of the lifter portion 7 advances, and the V blocks 51 and 52 move in the direction of the arrow in FIG. 5 to the next intermediate stop position M (downward). In other words, the rod of the cylinder 71 is extended from the cylinder 71 and lowered.

Next, the lifter portion 7 moves in the direction of the arrow (right direction) of FIG. 5 by advancing the rod of the second cylinder 62 of the second traverse portion 6 to the position state of FIG. The position becomes position (L2) on the hanger conveyance line rail of FIG.

(iii) The rod of the cylinder 72 of the lifter portion 7 is advanced, and the pin blocks 51, 52 move in the direction of the arrow (downward in Fig. 5) to the lower end thereof.

At the point in time (i), the supporter part 5 of the rod-shaped support body is at the lower end, and the rod-shaped support body is also in a position for mounting the shoe main body S. After that, the rod-shaped support body is supported by the shock block 52 having the chuck function on the opposite side of the separator of the supporter part 5, and waits with only one end supported. As the above-described shock block 51 is hindered when the separated shoe body S moves on the guide rail 37, it is lowered and is in the standby state as described above.

On the other hand, when the separation alignment of the predetermined number of shoe main bodies S is completed by the separator 31, the traversal cylinder 41 of the traverse portion 4 is caught by the gap C _w of the separator 31. A predetermined number of shoe bodies S move over the shoe guide rails 37 so that the rod-like supports penetrate the holes of the plurality of shoe bodies S.

After the step of passing the rod-shaped support body through the predetermined number of shoe bodies S is completed, the separator-side shock block 51 of the supporter part 5 of the rod-shaped support body is opened by the cylinder 54. Since it rises and the chuck | zipper 52a of the wedge block 52 on the opposite side of a separator opens, the rod-shaped support body only becomes a state where both ends are supported from below the wedge blocks 51 and 52. As shown in FIG.

(vi) After that, the supporter portion 5 of the rod-shaped support moves to the rising end by the action of the cylinders 71 and 72 of the lifter portion 7 and stands by.

(vii) If the hanger H in which the rod-shaped support is separated immediately before it moves in the moving direction indicated by the arrow in this state and is brought into a position that is properly engaged with the rod-shaped support that is waiting, the cylinder ( The rod 71 is moved forward. Thus, the rod-shaped support body on which the predetermined number of shoe bodies S is supported is caught by the hanger H.

The hanger H to which the rod-shaped support body on which the predetermined number of shoe main bodies S is supported is transferred, for example, to the inside of the surface treatment apparatus 300 of the step shown in FIG. A predetermined surface treatment is performed. When the hanger H exits the surface treatment apparatus 300, the shoe main body S automatically descends according to the form 2 described above. In other words, the rod-shaped support body which has passed through the shoe main body S which has passed through the surface treatment apparatus 300 of FIG. 7 and is suspended by the hanger H, has the lifter part 7 and the 2nd traverse part ( By the action of 6), it descends from the hanger H at the position L2 on a conveying line rail, and is sent to the two fin blocks 51 and 52 of the rod-shaped support supporter part 5. This is the action of the lower part of the rod-shaped support.

Subsequently, the rod-shaped support supported by the supporter portion 5 is transferred onto the shoe guide rails 37 of the supporter portion 5 and guided by the forward and retracting action of the first traverse portion 4. At the same time as the tip of the rail 37 (outlet side), the rod-like support penetrating the hole of the web of the shoe main body S is separated. This is the action of the rod-shaped support separator portion. By the linkage action of the rod-shaped support lower portion and the rod-shaped support separator portion, the shoe main body S is automatically lowered and placed in a dense alignment for the next step.

Since the rod-shaped support body vacated by lowering the shoe body S returns to the hanger H, an empty rod-like support body remains in the hanger H, and the shoe body S described above Leads to an automatically hanging device (100).

The operation of automatically hanging the shoe main body S described above and the operation of automatically lowering the shoe main body S continuously interlock with each other, thereby automatically hanging or hanging the plurality of shoe main bodies S to the hanger H. You can get off and on automatically.

The present invention provides a method of (A) carrying out a plurality of work objects such as a plurality of shoe bodies closely aligned, one by one with a shutter, (B) a method of separating and arranging a plurality of work objects by a separator, and (C) a plurality of work objects. A method of supporting these workpieces by penetrating the rod-like supports through the separated aligned workpieces, and (D) by placing the rod-shaped supports on or off the hangers, Since the work to be caught in the process and the work to be automatically unloaded from the hanger are enabled, the following effects can be enjoyed.

(1) Reduction of inventory in the stage, rationalization of logistics and labor reduction.

(2) Scratches and scratches generated when the work object is hanged on the hanger or when the work object is lowered from the hanger are eliminated, and the productivity is improved.

(3) The quality of the surface treated surface of the workpiece is improved because the operator does not directly contact the workpiece when the workpiece is hanged on or hanged from the hanger.

The present invention has been made to automatically carry out the work hanging on the work target installation hanger and the work unloading work at the stage in the case of the surface treatment apparatus or the like, which was conventionally performed by hand, it is possible to reduce labor and improve efficiency In addition, it has been found to contribute greatly to the reduction of inventory and the rationalization of logistics.

In addition, the hanging or unloading work can be automated so that no human hands are required at all. Thus, compared to the case of hanging or unloading the work by hand, wounds that were more likely to occur when hanging and unloading the work are easy. This eliminates other traces and reduces the defective rate, thereby improving productivity.

In addition, in the hanging or unloading of the work object, since the worker does not directly contact the work object, the adhesion of sebum or gloves to the fiber waste on the work object surface is eliminated, and the quality of the surface of the work object is treated. Improvement can be planned.

In addition, the present invention is applicable not only to automobile brake shoes, but also to other work objects manufactured by a manufacturing apparatus in which various steps are installed in association on a manufacturing line.
