Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The invention is designed to make it possible to change the feed rate of a long material according to the size of the processed product obtained by processing the long material. The present invention relates to a feed rate adjustment device for long material.

(Prior art) For example, when punching or cutting a paper tape-shaped insulating material and processing it into insulating paper for electrical equipment, the paper tape-shaped insulating material is transferred by a feeding mechanism to a processing device consisting of a press in predetermined pitches. However, when changing the size of the insulating paper for electrical components obtained by processing, the paper tape-shaped insulating material should be adjusted according to the size of the insulating paper for electrical components. It is necessary to change the feed amount.

The feed amount of the paper tape-shaped insulating material is determined by the stroke of the feed mechanism, so the feed amount can be changed by changing the stroke of the feed mechanism. A pneumatic cylinder is generally used as the drive source for this feeding mechanism, and when the pneumatic cylinder moves from the retreated position to the advancing direction, the stroke of the feeding mechanism is The change is made by changing the position of the stopper for stopping. in this case,
Conventionally, the stopper has been constructed of, for example, a threaded rod, and the position of the stopper has been changed by screwing the threaded rod forward and backward.

(Problem to be solved by the invention) However, in the conventional configuration described above, in order to change the stroke of the feed mechanism, the threaded rod for the stopper must be rotated many times, and the stroke must be set accurately. In order to do this, it is necessary to measure the amount of screw advance and retreat of the threaded rod one by one, which leads to the problem that a lot of time is spent on so-called setup, which reduces productivity.

This idea was made in view of the above circumstances,
The object is to provide an apparatus for adjusting the feed rate of a long material, which can change the stroke of a feed mechanism for changing the feed rate of the long material in a short time.

[Structure of the invention] (Means for solving the problem) The feeding rate adjusting device for a long material of the present invention includes a main body, and a device supported by the main body so as to be movable back and forth, and grips and feeds the long material. The elongated material is fed to the processing device by a predetermined pitch by a feeding mechanism comprising a movable body that releases the grip and moves back, and the movable table is provided so as to be movable along the longitudinal direction of the elongated material. While the above-mentioned feeding mechanism is attached to this movable base, a locking portion is provided protruding from the movable base, and a plurality of positioning pins each having a different amount of protrusion toward the locking portion are provided. A positioning mechanism that is driven by an actuator to selectively oppose the positioning pins to the locking portion is provided, and the locking portion is moved toward the positioning mechanism using a fluid pressure actuator such as a fluid pressure cylinder as a driving source. A pressing mechanism is provided that presses and fixes the locking portion to the selected positioning pin, and a stopper that abuts and stops the feed mechanism when the feed mechanism moves in one direction is fixed in a fixed position, and the lock is fixed to the selected positioning pin. The present invention is characterized in that the distance from the stopper is changed by changing the position of the movable base by changing the positioning part that fixes the part.

(Function) To change the feed rate of a long material, select a desired positioning pin from among the plurality of positioning pins that the positioning mechanism has, place it opposite to the locking part of the movable base, and then turn the pressing mechanism. When actuated, the pushing mechanism moves the locking portion to push it into place on the selected locating pin. Since the movable base moves integrally with the movement of the locking portion, the distance between the movable base and the stopper changes. Therefore, the stroke of the moving body of the feed mechanism changes, and the amount of feed of the elongated material can be changed.

(Example) An example of the present invention will be described below based on the drawings. Note that this embodiment is applied to the case where insulating paper for electrical equipment is processed from paper tape-shaped insulating material.

First, in FIG. 3, reference numeral 11 is a base installed on the floor, and on the right side of the base 11 in the figure is a support 12.
is installed, and a roll 1 in which a paper tape-shaped insulating material 13 as a long material is wound around this support 12.
4 is rotatably supported. A pair of rolls 15 and 1 are provided on the left and right sides of the upper surface of the base 11, respectively.
6 are provided, and movable tables 17 and 18 are placed on these rolls 15 and 16 so as to be movable in the left-right direction via rollers 17a and 18a. and,
A processing device 20 for punching and cutting the paper tape-shaped insulating material 13 to process the insulating paper 19 for electrical components shown in FIG. 4 is attached to the movable table 17 on the left side. is a feeding mechanism 21 for feeding the paper tape-shaped insulating material 13 to the processing device 20;
is installed.

Of these processing devices 20 and feeding mechanisms 21,
First, the feed mechanism 21 consists of a main body 22 fixed to the movable base 18 and a slider 24 as a moving body supported by a pair of guide bars 23 protruding from the main body 22.
The paper tape-shaped insulating material 13 is reciprocated in the longitudinal direction by a rod 25 of a pneumatic cylinder (not shown) provided in the paper tape-shaped insulating material 13. Further, as shown in FIGS. 1 and 2, an insertion hole 27 is formed in the upper part of the slider 24, and the upper part of the slider 24 is closed by a clamp receiving plate 26. A clamp 29 is provided which is moved up and down reciprocally by a pneumatic cylinder 28 provided in the holder. Reference numeral 30 denotes a clamp provided on the upper part of the main body 22, which is adapted to be reciprocated up and down by a pneumatic cylinder (not shown) provided within the main body 22. The paper tape-shaped insulating material 13 is placed between the clamp receiving plate 26 of the feeding mechanism 21 and the clamp 29, and between the clamp 3
0 and the upper surface of the main body 22.

A movable base 18 equipped with such a feeding mechanism 21
is fixed by a positioning mechanism 31 and a pressing mechanism 32 so that its position can be changed. That is, a rectangular bar-shaped locking part 34 is protruded from the lower part of the movable table 13 and extends through a long hole 33 formed in the base 11 and projects downward. The positioning mechanism 31 is attached to the mounting base 35 so as to correspond to the locking part 34, and the pressing mechanism 32 is attached to the base so as to be located on the opposite side of the positioning mechanism 31 with respect to the locking part 34. It is attached to the bottom of 11. This positioning mechanism 31 includes a disk 37 that is intermittently rotated by a predetermined angle by an electric or hydraulic actuator, such as a pneumatic rotary actuator 36, and the disk 37 is rotated toward the locking portion 34 side. A plurality of positioning pins 38 each having a different protrusion amount are attached. When the disk 37 is rotated, the positioning pin 38 is selectively opposed to the locking portion 34 depending on the rotation angle. Further, the pressing mechanism 32 is composed of a fluid pressure actuator, such as a pneumatic cylinder 39, and the movable base 18 is always urged in the direction of the arrow 41 by a tension coil spring 40 provided between the base 11. The locking portion 34 is always connected to the rod 39a of the pneumatic cylinder 39.
is in contact with. And pneumatic cylinder 3
When rod 39a of No. 9 advances in the direction of arrow 42,
The locking portion 34 moves integrally with the movable base 18 toward the positioning mechanism 31 against the elastic force of the tension coil spring 40, and comes into contact with the positioning pin 38. When the locking portion 34 comes into contact with the positioning pin 38, it stops and is pressed and fixed to the positioning pin 38 by the rod 39a, whereby the movable base 18 is also fixed at that position. Therefore, the fixed position of the movable table 18 can be changed by changing the positioning pin 38 that presses and fixes the locking part 34. 43 is a plate-shaped stopper fixed on the base 11 so as to face the slider 24 of the feeding mechanism 21;
This stopper 43 is for stopping the slider 24 in the middle of its movement by abutting the slider 24 when it moves in one direction, that is, in the direction of the arrow 44. Incidentally, the reason for changing the position of the movable base 18 will become clearer from the explanation of the operation described below, but the stroke of the slider 24 and the feed amount of the paper tape-shaped insulating material 13 are controlled by the processing device 2.
This is because the length is changed according to the size of the insulating paper 19 for electrical components to be processed, that is, the length l.

On the other hand, the processing device 20 includes a die 45, a punch 47 that is moved up and down by a pneumatic cylinder 46, and a cutter 49 that is moved up and down by a pneumatic cylinder 48. As will become clearer from the explanation of the action described later, the punch 47 is the die 45.
The cutter 49 works together with the punch 47 to punch out the notch 19a of the insulating paper 19 for electrical components shown in FIG. It acts to disconnect from 13. Insulating paper 19 for electrical components cut by cutter 49
is suction-held by a suction unit 50 of a conveyance device by so-called vacuum suction and conveyed to a predetermined location.

A movable base 17 on which such a processing device 20 is attached
It is also fixed by a positioning mechanism 51 and a pressing mechanism 52 so that its position can be changed. These positioning mechanisms 51
The configuration of the pressing mechanism 52 and the positioning mechanism 31 of the movable table 18 is the same as that of the pressing mechanism 32, so the same parts are denoted by the same reference numerals and a detailed explanation will be omitted. The reason why the movable base 17 is configured to be able to change its position is that when the insulating paper 19 for electrical components cut by the cutter 49 is sucked by the suction unit 50 of the conveying device, the insulating paper 10 for electrical components is If it is not adsorbed, there is a risk that it will fall during transportation, so by changing the position of the movable table 17, the suction unit 50 can adsorb the center of the electrical component insulating paper 19.

Next, to explain the operation of the above structure, first, the operation of the feeding mechanism 21 will be explained. That is, assume that the slider 24 is now moved in the direction of arrow 44 by the rod 25 of a pneumatic cylinder (not shown) and comes into contact with the stopper 43. Then, the clamp 3 of the main body 22
0 is moved upward by a pneumatic cylinder (not shown) and the paper tape-shaped insulating material 13 is connected to the main body 22.
At the same time, the clamp 29 of the slider 24 is moved upward by the pneumatic cylinder 28 to grip the paper tape-shaped insulating material 13 between it and the clamp receiving plate 26. Thereafter, the slider 24 is moved by the rod 25 in the opposite direction of the arrow 44, so that the paper tape-shaped insulating material 13 held by the clamp 29 is sent to the processing device 20 by a predetermined pitch. And the rod 25 is the anti-arrow 44
When the movement limit position in the direction is reached, the slider 24
stops, and at this stop position, the clamp 29 of the slider 24 moves downward and the paper tape-shaped insulating material 1
3, and release the clamp 30 of the main body 22.
moves downward and grips the paper tape-shaped insulating material 13. Thereafter, the slider 24 moves in the direction of the arrow 44 until it comes into contact with the stopper 43, at which time the clamp 30 of the main body 22 releases its grip on the paper tape-shaped insulating material 13, and the clamp 24 of the slider 24 releases its grip on the paper tape-shaped insulating material 13.
9 grips the paper tape-shaped insulating material 13. Thereafter, the slider 24 moves again in the direction opposite to the arrow 44, and feeds the paper tape-shaped insulating material 13 to the processing device 20 by a predetermined pitch. Slider 24 like this
The paper tape-shaped insulating material 13 is sent to the processing device 20 by a predetermined pitch by reciprocating movement, that is, movement in the opposite direction of arrow 44 (feed movement) and movement in the direction of arrow 44 (return movement).

Now, the operation in the case where the insulating paper 19 for electrical components is processed from the paper tape-shaped insulating material 13 fed in predetermined pitches as described above will be described. That is, first, the movable bases 17 and 18 move to the positioning mechanism 51.
31 and the pressing mechanisms 52 and 32, the electrical component insulating paper 19 to be processed is fixed at a position corresponding to the size thereof. In this state, when the slider 24 of the feeding mechanism 21 moves, the paper tape-shaped insulating material 13 is fed to the processing device by a predetermined pitch. Then, the processing device 20
Since the punch 47 is moved downward by the pneumatic cylinder 46, the punch 47, in cooperation with the die 45, punches out notches 19a on both sides of the paper tape-shaped insulating material 13. After this, the slider 24 was moved back during the punching process by the punch 47.
is fed and moved again, so paper tape-shaped insulating material 1
3 is again sent to the processing device 20 by a predetermined pitch amount, and the punch 47 punches the notch 19a in the paper tape-shaped insulating material 13 in the same manner as described above. At the same time as this punching, the cutter 49 is moved upward by the pneumatic cylinder 48, so that the cutter 49 cooperates with the knife edge portion 47a at the tip of the punch 47 in the lowered position, and the processing device 20
Then, the paper tape-shaped insulating material 13 sent out to the left in the figure by a length corresponding to the feed amount of the feeding mechanism 21 is cut. Insulating paper for electrical components 1 obtained in this way
9 is sucked at the center by the suction unit 50 of the conveyance device and conveyed to a predetermined location. Thereafter, the paper tape-shaped insulating material 13 is sequentially fed by a predetermined pitch by the feeding mechanism 21 in the same manner, and is processed into the electrical component insulating paper 19.

By the way, when changing the size of the insulating paper 19 for electrical components to be processed, the amount of feed of the paper tape-shaped insulating material 13 is adjusted and the suction unit 50 is adjusted so that it attracts the center of the insulating paper 19 for electrical components. In order to do this, the positions of both movable platforms 17 and 18 are changed. This position change is performed as follows. In addition, since the procedure for changing the position of both movable bases 17 and 18 is the same, the movable base 1
8 will be explained, and the explanation about the movable table 17 will be omitted. That is, first, the rod 39a of the pneumatic cylinder 39 is retreated in the opposite direction of arrow 42. Then, following the retreat of the rod 39a, the movable base 18 moves in the direction of arrow 41 by the elastic force of the tension coil spring 40 while keeping the locking portion 34 in contact with the rod 39a. With the locking portion 34 separated from the positioning pin 38 in this manner, the rotary actuator 36 rotates the disk 37 by a predetermined angle to select a desired positioning pin 38 facing the locking portion 34. do. After that, when the rod 39a of the pneumatic cylinder 39 is advanced in the direction of the arrow 42, the locking part 34 is pressed by the rod 39 and integrally rebounds with the movable base 18 against the elastic force of the tension coil spring 40. Move in the direction of arrow 41. Then, the positioning pin 38 with the locking portion 34 selected
When it comes into contact with the movable base 18, the locking portion 34 (movable base 18) stops and is pressed and fixed to the positioning pin 38 by the rod 39a, thereby fixing the movable base 18 at that position.

When the positioning pin 38 that presses and fixes the locking part 34 is changed as described above, the position of the movable base 18 changes to the left or right by the difference in length between the positioning pin before and after the change. .
Due to this change in the position of the movable base 18, the movable base 18
The distance between the main body 22 of the slider 24 and the stopper 43 fixed in a fixed position changes.
The distance between the sideward movement limit position and the position where it comes into contact with the stopper 43 and stops changes, that is, the stroke of the slider 24 changes, thereby changing the feed amount of the paper tape-shaped insulating material 13. It is possible.

Note that when the position of the movable base 17 is changed in the same manner as described above, the distance between the cutter 49 and the suction section 50 changes, so that the suction section 50 can suction the center of the electrical component insulating paper 19. This is what happens.

According to this embodiment, when adjusting the feed amount of the paper insulating material 13 by the feeding mechanism 21, the paper tape-shaped insulating material 13 of the movable table 18 is moved in the left and right direction along the feeding direction and fixed. Moreover, the amount of movement can be set by rotating the disc 37 using the rotary actuator 36 and adjusting the positioning pin 3.
8, the desired one can be automatically set by simply facing the locking part 34, and the movable base 18
The movement and fixing can be performed automatically by moving the rod 39a of the pneumatic cylinder 39 in the direction of the arrow 42, so the setup work can be done very easily and in a short time, improving productivity. can be done.

Further, the feed amount (stroke) of the slider 24 of the feed mechanism 21 can be adjusted by changing the fixed position of the movable base 18 to adjust the distance between the main body 22 of the feed mechanism 21 and the stopper 43 fixed to the base 11. Therefore, there is no need for the stopper 43 for stopping the movement of the slider 24 in the direction of the arrow 44 to be movable for adjusting the feed amount. Therefore, since the stopper 43 can be fixed in position, it can be made large and sturdy in terms of structure, and the slider 24 comes into impactful contact with the stopper 43 for each feeding operation. Even under certain circumstances, the stopper 43 will not cause any "backlash" or wear and tear, resulting in a long service life.
There is no risk of deviation in the feed amount in step 3.

On the other hand, for example, the main body 22 of the feeding mechanism 21 is fixed to the base 11, and a positioning mechanism 31 is provided on the base 11 instead of the stopper 43, and the positioning mechanism 31 moves the slider 24 in the direction of the arrow 44. If the slider 24 is configured to stop the slider 24 and adjust the feed amount of the slider 24, the slider 24 will come into impactful contact with the positioning pin 28 every time the slider 24 is moved. However, the positioning pin 38 is thin, and if it is subjected to repeated impacts due to contact with the slider 24, it will wear out and deteriorate. Further, the positioning pin 38 is attached to a disk 37, and the disk 38 is attached to a rotating shaft (not shown) of the rotary actuator 36, but the rotating shaft originally has a slight " Since the slider 2 is supported with some backlash, the slider 2 is attached to the positioning pin 38.
4 repeatedly comes into contact with impact, the rotating shaft of the rotary actuator 36 receives repeated impact and the "backlash" increases, and as a result, the stop position of the slider 24 and the paper tape-shaped insulating material 13
There is a possibility that the feeding amount may be incorrect. However, in this embodiment, such a problem does not occur as described above.

In the above embodiment, the pneumatic rotary actuator 36 was used as the drive source for the disc 37, but this could be a hydraulic rotary actuator,
Alternatively, an electric actuator such as a step motor may be used instead, and a hydraulic cylinder may be used as the drive source for the pressing mechanism 32.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be applied to a device that feeds a long metal plate to a processing device by a predetermined pitch, without departing from the gist. Various modifications are possible.

[Effects of the invention] As is clear from the above explanation, in the present invention, when adjusting the feed amount of a long material, it is sufficient to move the movable base to which the feed mechanism is attached by a desired amount and then fix it. can be set automatically by simply placing a desired positioning pin from among the plurality of positioning pins of the positioning mechanism facing the movable base, and the movable base can be moved and fixed automatically by the pressing mechanism. Therefore, the setup work for adjusting the feed rate can be completed very simply and in a short time, and productivity can be improved.
Moreover, the stopper that abuts and stops the moving body when the feed mechanism moves in one direction can be fixed at a fixed position, so the stopper can be constructed large and sturdy. As a result, there is no risk that the stopper will cause backlash or premature wear and tear, and it has the excellent effect of being able to maintain highly accurate feed operation over a long period of time. .
