Description

[Detailed description of the invention] After the shoe is grown, the shoe is released from the last with the tread facing upward, and the shoe is transported to a predetermined position and then turned over so that the tread is facing downward. The present invention relates to a release and transfer device for shoes, which allows shoes to be released and then dropped onto a placing section.

The present applicant has previously proposed a device of this type in which both outer surfaces of the heel of a shoe are held between a pair of openable and closable holding bodies, released from the mold, and transferred (in actual practice). (Sho 59-34604). In this device, since the heel of the shoe is held between both holding bodies,
If the size of the shoe is large, there is a risk that the toe side will drop due to the weight when the shoe is being transported, and the shoe may fall from between the two clamping bodies. In order to solve this problem, each clamping body is provided with a presser plate that protrudes from its inner surface and comes into contact with the tread of the heel.
In this case, if the presser plate is fixed to the clamping body, the sole of the shoe will get caught on the presser plate when the shoe is turned half so that the tread is facing downward, and when both clamping bodies are opened and dropped onto the placement part. This may cause problems such as not being correctly placed on the placing section or dropping from the placing section.

This invention aims to solve the above problems,
The presser plate is moved away from the inner surface of the holding body when the shoe is dropped onto the placement part.

Manufacture.

The vane 35 of the actuator 32 in the unlocking device 4 is initially rotated counterclockwise to its terminal position as shown in FIG.
As shown in FIG. 4, the lock handle 3 is disposed obliquely so that its tip is located diagonally above and away from the lock handle 20. The rod-shaped portion 19 of the lock handle 20 in the first foot _last 101 is designed to be located within the rotation locus of the operator 33 when the heating cylinder 26 is in the forward position.
₂ , when the first suction/discharge hole 36 ₁ of the actuator 32 is communicated with the pneumatic unit 42 and the second suction/discharge hole 36 ₂ is communicated with the atmosphere using the electromagnetic switching valve 43, as described above, The operator 33 rotates 180° clockwise in Fig. 4 and locks the lock handle 2.
0 from above and rotate it clockwise in FIG. 4 to bring the locking device 16 into the unlocked state. As a result, the bottom surface of the heel portion 10b of the first _last 101 protrudes from the bottom surface of the last main body 10a, the close contact between the last main body 10a and the inner surface of the sole So is released, and the length of the last is shortened. A similar unlocking operation is performed for the locking device 16 of the second last ₁₀₂ .

Next, the rotary table 2 is intermittently rotated counterclockwise in FIG. 1 to stop the first and second foot lasts 10 ₁ and 10 ₂ at the position of the manipulator 5.

Before the mold release operation, as shown in FIGS. 11 and 12, the hand 50 of the manipulator 5 horizontalizes the first and second fingers 55 ₁ and 55 ₂ and opens them to return to the original position a near the conveyor 6. It is in. Further, since both rotating mechanisms 77 are inoperative, the first and second presser plates 61 ₁ and 61 ₂ are open as shown by the chain lines in FIG.

During mold release operation, arm 4 is moved according to the program.
8 swings and bends toward the second foot last 10 ₂ located at the top, and the cylinder body 54 rotates around the support shaft 53 to move the first and second fingers 55 ₁ ,
While moving forward, the fingers 55 _{1 and} 55 2 are held at approximately 45°, which matches the inclination of the tread of the sole So, and the fingers 55 ₁ and 55 ₂ are located on both sides of the heel Sh of the shoe S at a position c after passing through a position b. At this time, the switching valve 6 in FIG.
7 is switched to the high pressure setting pressure reducing valve 69 side,
Since high pressure air is introduced into the closing pressure chambers 72 ₁ and 71 ₂ from the on-off valve 68, the first and second fingers 55
₁ and 55 ₂ are closed, and the heel Sh of the shoe S is clamped. In this case, the first and second fingers 55 ₁ and 55 ₂ move independently of each other in the closing direction, so that due to the difference in the shape of the left and right sides of the shoe S, the stopping position of the first and second fingers 55 1 and 55 2 is set to one of the fingers 55 ₁ and 55 ₂ Even if it is biased to the side, the heel Sh can be reliably held between the fingers 55 ₁ and 55 ₂ . When both fingers 55 ₁ , 55 ₂ close, both rotating mechanisms 77 are activated by the signal, so that both holding plates 61 ₁ , 61 ₂ are closed as shown by solid lines in FIG.
are closed, and their tips protrude from the inner surface of the thin portion 60a and come into contact with the tread surface of the heel Sh.

Next, the first and second fingers 55 ₁ and 55 ₂
They rise from position c to position d so as to draw a trajectory substantially along the sliding surface of heel portion 10b and last body 10a. During this time, the heel portion 10b of the second last 10 ₂
As the first and second fingers 55 ₁ and 55 ₂ move, they slide against the last body 10a and the length of the last is shortened, so that the toe portion of the last body 10a and the toe portion of the shoe S are A gap is created between them as shown in FIG. 13a, which facilitates the next heel release operation of the shoe S.

Then, while the first and second fingers 55 ₁ and 55 ₂ rise diagonally backward from position d to position e, the first
4a and 14b, the first and second fingers 55 ₁ and 55 ₂ are connected to the heel part Sh of the shoe S.
It comes off from the heel part 10b of the last 10 ₂ , but before it comes off, the switching valve 67 is switched to the low pressure setting pressure reducing valve 70 side to reduce the air pressure in the closing pressure chambers 72 ₁ and 72 ₂ .
The heel portion of the shoe S of the first and second fingers 55 ₁ , 55 ₂
Reduces clamping pressure on Sh. As a result, the first and second fingers 55 ₁ , 55 ₂ are connected to the second foot last 10 ₂
It is possible to avoid the problem that when the sole part So of the shoe comes off from the heel part 10b, the uncured sole part So immediately after molding is strongly pressed by the first and second fingers 55 ₁ and 55 _{2 and} deformed.

While the first and second fingers 55 ₁ and 55 ₂ rise diagonally backward from position e to position f, the heel of the shoe S
As clearly shown in FIGS. 15a and 15b, Sh completely separates from the heel portion 10b of the second last ₁₀₂ .

After that, the first and second fingers 55 ₁ , 55 ₂
When the shoe S advances obliquely upward substantially parallel to the bottom surface of the last 10 ₂ and reaches position g, the toe of the shoe S slips out from the toe of the last main body 10 a and the shoe S is completely separated from the second last 10 ₂ . Next, the first and second fingers 55 ₁ , 55 ₂
rises from position g to position h. In this case, since both presser plates 61 ₁ and 61 ₂ are in contact with the tread surface of the heel part Sh, the toe side does not fall down due to their weight, and therefore the shoe S is lowered from between the fingers 55 ₁ and 55 _2. There is no risk of it falling. Then, while the first and second fingers 55 ₁ and 55 ₂ are retreating from position h to i, they rotate 180 degrees so that their treads are directed downward, and the first and second fingers 55 1 , 55 2
When the second fingers 55 ₁ and 55 ₂ are lowered to position j, the shoes S are located above the conveyor 6 as a placement section. Then, the on-off valve 68 is switched and the closing pressure chambers 72 ₁ , 72 ₂ are opened to the atmosphere, and at the same time pressurized air is introduced into the opening pressure chambers 71 ₁ , 71 ₂ , so that the first and second fingers 55 _{1,55 2} opens,
Further, during the opening operation, the rotating mechanism 77 is inactivated by the signal, so that both the holding plates 61 ₁ and 61 ₂ are also opened.
Therefore, the shoes S are dropped onto the conveyor 6 without being obstructed by both presser plates 61 ₁ and 61 ₂ .

Next, while the first and second fingers 55 ₁ and 55 ₂ advance diagonally upward from position j to position k, both fingers 55 ₁ and 55 ₂ rotate 180°, return to their original state, and then 1. Second finger 55 ₁ ,
55 ₂ descends diagonally backward, retreats, and returns to the original position a.

After the above mold release and transfer operations are completed, the second foot mold 10 ₂ is rotated 180 degrees and the unreleased first foot mold 10 ₁ is rotated 180 degrees.
is positioned upward, and the same operation as above is performed.

As described above, according to the present invention, the shoes S attached to the lasts 10 ₁ and 10 ₂ are released with the treads facing upward, and the shoes S are transferred to a predetermined position, and the treads are turned downward. This device is designed to release and transfer shoes by inverting the shoe S and dropping it onto the placing section 6.The device grips both sides of the heel part Sh of the shoe S during release and transfer, while the heel part Sh is placed on the heel part when the shoe is placed. a pair of clamping bodies 55 ₁ and 55 ₂ that are openable and closable and rotatable around an axis perpendicular to the opening and closing direction, which releases Sh;
During mold release and transfer, the holding plates 61 ₁ , 61 ₂ protrude from the inner surface of each clamping body 55 ₁ , 55 2 and come into contact with the tread surface of the heel part Sh, while when placed, they retreat from the inner surface of each clamping body 55 ₁ , 55 _{2 .} Therefore, when transporting the shoes S, there is no risk that the shoes S will fall from between the holding bodies 55 ₁ and 55 ₂ . Furthermore, since the presser plates 61 ₁ and 61 ₂ do not get in the way when the shoes S are dropped onto the mounting section 6, the shoes S can be placed correctly on the mounting section 6.
