Abstract

PROBLEM TO BE SOLVED: To solve the problem that a thermoformed article should be ejected manually to lower work efficiency, and in order to trim the article on-line by a die press, not only a trimming cycle should be followed but also separated scraps and a product should be separated while they are discharged simultaneously so that the separation in good timing has been difficult. SOLUTION: The thermoformed article trimmed by the die press is conveyed with the scraps onto an opened table 20. While a dropping door 23 closing an opening 22a during the stop of intermittent sending is opened, the article is pushed under the opening 22a from above by a pushing arm 50 and mounted on the table plate 34 of an elevator 30 located below the opening 22a. When the articles piled on the table plate 34 reach a prescribed number of steps, the articles are transferred onto the belt conveyer 41 of an ejection table 40, so that the articles can be ejected while being operated on line.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermoformed product take-out stacker in which a thermoformed product is trimmed from a thermoformed thermoplastic resin sheet by a die press, and then the thermoformed product is separated from scrap and taken out.

[0002]

2. Description of the Related Art Conventionally, a trimming apparatus using a die press has been arranged off-line with respect to a thermoforming line for forming a thermoformed product on a resin sheet. The sheet made from the thermoforming line is taken out from the thermoforming line, cut into a predetermined size, a plurality of the sheets are superimposed, and the thermoformed product is cut off by a trimming device. And
The excised thermoformed product is almost manually removed.

[0003]

As described above, in the trimming apparatus which is used off-line, the removal of the thermoformed product must be performed manually, which is not efficient. In addition, in order to perform trimming by die press online, not only follow the thermoforming cycle, but also
Since the separated scrap and the product must be separated while being discharged at the same time, it has been difficult to separate the scrap with good timing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a thermoformed product take-out stacker capable of efficiently taking a thermoformed product online in accordance with trimming by die press.

[0005]

In order to achieve the above object, the invention according to claim 1 is provided with an opening disposed in a discharge path of a trimmed thermoformed product and a scrap so that the thermoformed product can be discharged downward. An opening table having an opening, a drop door capable of opening and closing the opening, and opening at a timing when the thermoformed product is located at an upper portion of the opening, and a drop door disposed above the opening table and synchronized with the opening timing of the drop door. A push arm for pushing the thermoformed product into the opening, and an elevator capable of stacking and holding the thermoformed product dropped and dropped below the opening and controlling the height position according to the number of stacks And a take-out table for taking out the thermoformed product held on the elevator.

[0006] In the invention according to claim 1 configured as described above, the opening table is disposed in the discharge path of the trimmed thermoformed product and the scrap, and the trimmed thermoformed product is collected together with the scrap to be collected. It moves on the opening table. An opening through which the thermoformed product can be discharged downward is formed in the opening table, and a dropping door capable of opening and closing the opening is opened at a timing when the thermoformed product is located above the opening. Although the thermoformed product falls just by opening the falling door, the pushing arm arranged above the opening table pushes the thermoformed product into the opening in synchronization with the opening timing of the falling door. Then, since the elevator is arranged below the opening, the thermoformed products that are pushed in and fall are stacked and held. In general, in the case of a thermoformed product with an opening facing downward, the fall path is unstable if it falls naturally, but if the pushing arm is pushed in at a speed higher than the drop speed, the thermoformed product must be moved to the expected position Can be. In addition, since the elevator can stand by at the height position corresponding to the number of stacks, by setting the height position so that the pressed thermoformed products are stacked at the top level, the thermoformed products may be crushed by the pushing arm Disappears. In addition, the sheets are stacked one after another without being overlapped at the correct position, and there is no possibility that the sheets collapse on the way.

[0007] Since the opening table is generally arranged adjacent to the die press, the thermoformed product trimmed by the die press is separated from the scrap. However, the thermoformed product whose outer shape has been trimmed can be moved as it is in the horizontal plane in the sheet direction as the scrap moves. In order to move the thermoformed product in this manner, the invention according to claim 2 is the thermoformed product removal stacker according to claim 1, wherein the opening table includes a tension roller that feeds the scrap with a predetermined tension. It has a configuration to have.

In the invention according to claim 2 configured as described above, a predetermined tension is applied to the scrap by the tension roller. In this way, the thermoformed product moves relatively smoothly from the die press onto the opening table. The die press and the thermoformed product take-out stacker may be integrated or separated, and the shape of the die changes according to the shape of the thermoformed product. It is difficult to make it constant. Therefore, a third aspect of the present invention is the thermoformed product removal stacker according to the first or second aspect, wherein the opening table is supported to be vertically movable.

In the invention according to claim 3 configured as described above, since the opening table is supported so as to be able to move up and down, it is possible to adjust the height with the die press. When the height is adjusted in this way, the thermoformed product naturally moves onto the opening table only by sending out the scrap. An opening is formed in the opening table,
The thermoformed product is dropped by opening and closing the drop door provided at the opening as appropriate. Various structures can be adopted for the structure of the falling door. As an example, the invention according to claim 4 is the same as the structure of the thermoformed product removal stacker according to any one of claims 1 to 3 described above. The falling door is configured to slide reciprocally on the opening table from above the opening toward the downstream side in the flow direction of the scrap.

[0010] In the invention according to claim 4 configured as described above, the falling door slides reciprocally on the opening table from the upper portion of the opening toward the downstream in the flow direction of the scrap. Initially, the falling door is located above the opening and closes the opening, so that even if the thermoformed product moves together with the scrap, it does not fall from the opening.
When the falling door moves toward the downstream side in the scrap flow direction at the timing when the thermoformed product is completely located above the opening, the opening is opened and the thermoformed product falls downward as described above. Go. At this time, after the pushing arm pushes down the falling article, it retreats upward. After this retreat, the falling door moves to the upper side of the opening again to close the opening.

[0011] The falling door first moves downstream, but the thermoformed product is removed from the downstream scrap. Even if the falling door moves downstream in this way, the falling door is caught by the thermoformed product. Never. If an attempt is made to move to the upstream side, the thermoformed product that moves with the scrap may be caught. After the thermoformed product falls, it returns to the upstream side, but only returns to the place where the thermoformed product has already fallen, and does not catch on the thermoformed product.

Since the pushing arm is pressed against each thermoformed product from above, it is necessary to correspond to the position of the thermoformed product. Therefore, a fifth aspect of the present invention is the thermoformed product removal stacker according to any one of the first to fourth aspects, wherein the pushing arm has a plurality of detachable rod-shaped members, The position can be adjusted to face the molded product. In the invention according to claim 5 configured as described above, the pushing arm is constituted by a plurality of detachable rod-like bodies and the position thereof is adjustable, so that the shape of the thermoformed product can be adjusted according to the mold. Even when the position changes, the position can be easily adjusted to cope with the change. Further, by changing the length of the rod-shaped body, it is possible to cope with the height of the thermoformed product.

The elevator waiting for the falling compact is an elevator. As an example of the configuration of the elevator, the invention according to claim 6 is the stacker according to any one of claims 1 to 5. Wherein the elevator has a counter for counting the number of drops and a position adjusting mechanism for gradually lowering the height position by a predetermined distance according to the count. In the invention according to claim 6 configured as described above, the number of falling thermoformed products is counted by a counter, and the height position of the elevator is lowered according to the number of stacked stages. Although the thermoformed product is pushed down by the pushing arm, the pushing depth at this time should not be so deep. However, if the height of the elevator is kept high from the beginning, the thermoformed product becomes high immediately, and if it is left as it is, the thermoformed product may be crushed when pushed down. For this reason, if the elevator position is set as high as possible at first and the elevator is lowered by the thickness as the thermoformed products are stacked, thermoforming from the first state of stacking to the last state The pressing depth of the product can be made constant. Of course, the position does not have to be deep.

The thermoformed product held by the elevator is carried out to a take-out table. As one example of the take-out table, the invention according to claim 7 is the thermoformed product take-out stacker according to any one of claims 1 to 6, wherein the take-out table is substantially at a lowermost position of the elevator. The belt conveyor is arranged so as to be flush with the belt conveyor, and has a slide arm that moves from the innermost position of the elevator toward the upper surface of the belt conveyor at the lowermost position.

In the invention according to claim 7 configured as described above, the belt conveyor is arranged close to the lowermost position of the elevator so as to be substantially flush, and the elevator holds the thermoformed product. When they are lowered to the lowermost position in the state, they are arranged substantially horizontally. In this state, since the slide arm moves from the back side position of the elevator toward the belt conveyor, the thermoformed product held by the elevator is pushed out onto the belt conveyor, and if the belt conveyor is driven, It is carried out while it is on the belt.

In order for the sliding arm to move from the position on the back side of the elevator onto the belt conveyor, there must be no mechanical elements interfering between them, as one example. According to the present invention, in the thermoformed product take-out stacker according to claim 7, the elevator is configured to take out the table from which the thermoformed product is mounted, a column oriented substantially vertically, and the column. A support arm extends so as to protrude from the side to the back, supports the table plate at its tip, and has a support arm that is driven up and down along the column.

In the invention according to claim 8 configured as described above, the elevator has, as its basic structure, a column oriented substantially vertically, and the support arm is driven up and down along the column. Thus, the table plate on which the thermoformed product is placed is moved up and down. And this support arm is extended so as to protrude further from the take-out side than the same column and supports the table plate at its tip, so there is a distance from the position of the table plate to the column, and there is a belt. The conveyor can reach that far side. Accordingly, even if the slide arm itself reciprocates only on the back side of the column so as not to interfere with the column, it can freely move from the table plate to the belt conveyor.

[0018]

As described above, according to the present invention, the thermoformed product trimmed by the die press and carried out of the die press together with the scrap is dropped below the opening of the opening table. A thermoformed product removal stacker that can be removed can be provided. Further, according to the second aspect of the present invention, by sending the thermoformed product while applying tension by the tension roller, it is possible to prevent the thermoformed product from being easily caught when it is taken out.

Further, according to the invention of claim 3,
The height of the table surface can be made even when adjacent to the die press, so that the thermoformed product can be hardly caught when being taken out. Further, according to the invention according to claim 4, since the falling door is moved only downstream of the opening, it does not move below the scrap accompanied by the thermoformed product, and is caught when the thermoformed product is taken out. Can be difficult.

Further, according to the invention of claim 5,
A push arm having an appropriate length can be arranged at an appropriate position according to the arrangement of the molded product. Further, according to the invention according to claim 6, by lowering the elevator according to the number of stages of the thermoformed products to be laminated, the height of the uppermost stage can be always kept constant, and the thermoformed products are prevented from being collapsed. Can be laminated. Further, according to the invention according to claim 7, the thermoformed product held on the elevator can be easily taken out using the belt conveyor.

Further, according to the invention of claim 8,
The sliding arm can be configured without interfering with the columns that form the elevator.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a stacker for taking out a thermoformed product according to an embodiment of the present invention.
FIG. 2 is a plan view, and FIG. 3 is a front view. In FIG. 1, an opening table 20 is provided above the four-legged frame 10 as a reference, an elevator 30 and a take-out table 40 are provided inside the frame 10, and supported by another structure above the frame 10. The pushing arm 50 is arranged.

The opening table 20 shown in FIG.
0 is vertically movably supported by a vertical movement mechanism 21 using a ball screw shown in FIG. In the vertical movement mechanism 21, the sprocket 21a1
The endless chain 21b is disposed so as to be drivable through the shaft, and the chain 21b can rotate a female screw 21c provided at the upper end of the four legs in a predetermined direction. Each female screw 21c is rotatably supported on the upper end of the leg so as not to move up and down, and is screwed to the ball screw 21d. The upper end of the ball screw 21d is the table frame 21.
f, the motor 21
a, the chain 21b is driven in a predetermined direction to
When 1c rotates, the bolt screw 21d moves up and down relatively and the table frame 2 fixed to the upper end.
1f moves up and down. The vertical movement mechanism 21 is also shown in FIG.

In this embodiment, the ball is driven up and down by such a ball screw mechanism driven by a chain. Also, the ball screw mechanism may be manually moved up and down. Further, although the opening table 20 is moved up and down, the frame 10 may be configured to extend vertically in the whole. In addition, instead of being independent on the frame 10, the frame 10 may be attached to an adjacent die press (not shown) at a predetermined height position.

As shown in FIG. 2, a table 22 having an opening 22a is provided above the opening table 20, and a drop door 23 is provided so as to close the opening 22a. On both sides of the table plate 22, slide shafts 24a are disposed horizontally in the front-rear direction, and sliders 24 fixed slidably in the axial direction with respect to the respective slide shafts 24a.
b is provided. The falling door 23 is fixed to the sliders 24b, 24b on both sides so as to straddle the table plate 22, and can slide horizontally on the table plate 22 in the front-rear direction.

Here, the opening 22a is arranged on the front side (right side in the figure) of the table plate 22, and the falling door 23 closes the opening 22a at the sliding position on the front side. In this closed position, the falling door 23 is located at substantially the same position as the front end of the table plate 22. On the other hand, when opening the opening 22a, the falling door 23 moves in parallel to the rearward slide position, but at this slide position, the opening 22a opens substantially to the front.

An endless chain 25a is arranged in parallel with each of the slide shafts 24a, 24a, and is rotatable in a desired direction by a motor 25b. Since the falling door 23 is fixed to a part of the chain 25a, when the motor 25b is rotated in a predetermined direction, the falling door 23 is driven in the front-rear direction. In this example, one drop door 23 closes the entire surface of the opening 22a.
It is composed of two falling doors that open and close in the front-rear direction below the opening table plate 22, or the falling door 23 is not driven in the horizontal direction, but is pivotally supported on one side to open one side or both sides. It may be configured to open and close downward.

At the rear end side of the opening table 20, a drive roller 26a having a length almost full in the width direction is provided, and a drive motor 26b is connected to the end. An idler 26c is provided on the drive roller 26a, and the idler 26c is driven by an actuator 26d.
It can be pressed and released toward 6a. A predetermined tension is always applied to the scrap by holding the scraper therebetween while pressing the idler 26c against the drive roller 26a and rotating the drive motor 26b. That is, the drive roller 26a and the idler 26c constitute a tension roller.

Needless to say, the tension applied to the scrap is not limited to the combination of the idler 26c and the driving roller 26a, but may be a combination of a claw-shaped roller. As shown in FIGS. 1 and 6,
An elevator 30 is provided inside the frame 10. The elevator 30 includes columns 31, 31 which are vertically disposed inside the frame 10 and are covered by a cover. The columns 31, 31 have a slide shaft (not shown). A support arm 32 is slidably supported along the axial direction on the slide shaft.
1, a drive chain 31a and a drive motor 31
b drives up and down to an arbitrary position along the slide axis. The support arm 32 extends forward from the column 31 and is formed so as to extend obliquely upward and forward from the front end thereof. The horizontal bar 33 supports a table board 34 oriented in the horizontal direction.

The reason why the support arm 32 has such a shape is to move the thermoformed product to the take-out table 40. The take-out table 40 has a belt conveyor 41 extending so as to protrude out of the frame 10 from the position of the column 31 of the elevator as shown in FIGS. 1 and 6. In the figure, a shorter fixed table 42 is arranged in the length direction. Elevator 3
0 table plate 34 can be lowered to a height position that is substantially flush with the fixed table 42, and at this position, the sliding arm 43 that is driven in the horizontal direction is moved from above the table plate 34 to the fixed table 42. It can be moved horizontally backward through the top.

That is, as shown in FIG. 3, the slide arm 43 has the same length with respect to the drive bar 43a supported by the side as to have a length substantially equal to that of the table plate 34.
4, a punch plate 43b arranged vertically so as to be able to scrape out the mounted object is fixed, and the driving bar 43a is horizontally parallel in the front-rear direction by a side post 44 having a motor 44a and a driving chain 44b built therein. It is movable. That is, the drive chain 44b is driven by rotating the motor 44a in the side post 44,
The drive bar 43a is moved in the front-rear direction. Then, the punch plate 43 b is moved from above the table plate 34 to the fixed table 4.
It moves to the front end part of the belt conveyor 41 via the upper part of 2. That is, the object placed on the table board 34 is pushed and moved to above the belt conveyor 41.

At this time, the support arm 3 of the elevator 30
2 protrudes forward from the column 31 and extends further obliquely forward as described above,
Is located considerably forward of the support 31, and the front end of the belt conveyor 41 is also located forward by that much. On the other hand, in order for the slide arm 43 to move the thermoformed product on the table plate 34 to the belt conveyor 41, the punch plate 43b
Has to move to the front end portion of the belt conveyor 41, but since the column 31 is located considerably rearward, the drive bar 43a and the column are disposed even though the side post 44 is located outside the column 31. 31 does not interfere.

The length of the belt conveyor 41 can be appropriately determined according to the arrangement position and the like. The one shown in FIG. 1 has a caster 41a for supporting the belt conveyor 41 at the rear end position. In the present embodiment, the molded product is moved so as to be pushed out from the elevator 30 to the take-out table 40 by the slide arm 43. However, the molded product can be appropriately deformed, such as being inclined and sliding down. Further, the belt conveyor 41 is not essential, and may be taken out via another transport mechanism. Needless to say, the molding may not be completed by this, but may be carried to the next step using the belt conveyor 41.

FIGS. 1 and 3 show the pushing arm 50. The pushing arm 50 is vertically movably supported while being arranged in parallel with the driving shaft 51 and connected to the driving shaft 51 via the horizontal bar 53a at the upper end. And a connecting shaft 53b connected to the mounting arm 54 at the lower end. That is, the central portion and the outer portion of the mounting arm 54 oriented in the width direction of the molded sheet are suspended and supported, and the mounting arm 54 can be vertically moved while maintaining a horizontal state as a whole. I have. The mounting arm 54 has a plurality of rods 5 which can be set at a desired position interval and whose length can be adjusted.
5 is attached. Each bar 55 faces from above the thermoformed product, and is driven downward when the drop door 23 is opened, and serves to push the thermoformed product downward. For this reason, the length of the thermoformed product is also adjusted according to the height of the thermoformed product and the drop distance for stacking the thermoformed product on the elevator 30.

Since the pushing arm 50 only has to play the role of pushing down each thermoformed product, various configurations other than the use of the actuator 52 described above are possible. For example, if the front end can be moved in an arc shape while rotatably supporting the rear end at the rear end side of the table frame 21f of the opening table 20, the front end can be arced above the front end side of the table frame 21f. Move up and down while drawing. What is necessary is just to drop a thermoformed product using this vertical movement.

FIG. 7 is an electric block diagram for controlling the configuration of each unit described above. The control circuit 60 has a control circuit 60 for inputting an external control signal to control the operation timing of each unit. The motor 25b for driving the door 23, the actuator 52 for the pushing arm 50, the driving motor 31b for the elevator 30, and the motor 4 for driving the sliding arm 43
4a are connected, and the driving is controlled at a predetermined operation timing shown in FIG. In addition, a drive signal is appropriately transmitted to a drive motor 26b and an actuator 26d for applying tension to the scrap.

Such a control circuit 60 can be constituted by a computer control circuit based on a CPU, and its control can be appropriately changed by software. Further, at least a counter 61 is provided inside, and the number of laminating stages of the thermoformed product is detected by counting the number of times of opening and closing of the falling door 23, and the elevator 30 is gradually lowered or the slide arm 43 is operated at the lowest stage. The elevator is returned to the uppermost stage. The control circuit 60 can also be realized by a sequencer using various hardware elements.

Next, the operation of this embodiment having the above configuration will be described. FIG. 8 is a timing chart showing the operation of the present thermoformed product take-out stacker, and the operation will be described with reference to this timing chart. In the trimming operation, the thermoplastic resin sheet is intermittently driven. Accordingly, the thermoformed product which is trimmed and conveyed together with the scrap is also intermittently conveyed, and the thermoplastic resin sheet also intermittently moves on the opening table 20. When the door 23 is stopped,
The distance between the die press and the stacker for taking out the thermoformed product is adjusted so as to be positioned above.

As shown in FIG. 8, the operation of opening the falling door 23 in synchronization with the stop timing of the thermoplastic resin sheet and closing it before starting the movement is repeated. Falling door 2
The actuator 52 of the pushing arm quickly moves downward in accordance with the opening of the opening 3, and the thermoformed product immediately after the opening of the drop door 23 is reliably pulled away from the scrap and pushed down below the opening 22a. Initially, the table plate 34 of the elevator 30 is located at the uppermost stage, and the thermoformed product pushed down by the bar 55 of the pushing arm 50 is placed on the table plate 34. At this time, the thermoformed product is not merely an unstable free fall but is forcibly pushed down, so that the thermoformed product is accurately placed at an expected position.

The rod 55 is instantly retracted upward, and the falling door 23 is also closed. As described above, the falling door 23 moves to the downstream side in the scrap flow direction and opens, moves to the upstream side and closes. Since the thermoformed product is removed on the downstream side,
There is no snagging, and no snagging on the upstream side because the thermoformed product was removed immediately before. In this way, the table plate 34 is lowered as the thermoformed articles are placed one by one on the table plate 34. The lowered height is basically the height required for stacking thermoformed articles. Therefore, the height of the uppermost layer of the laminated thermoformed products is constant at any stage.

Either reaching a predetermined number of stacking stages or the elevator 30
Is reached, the motor 44a is driven in a predetermined direction to reciprocate the slide arm 43 back and forth. At this time, it is moved slowly toward the rear side, and at high speed when returning. In this way, the laminated thermoformed products are moved onto the belt conveyor 41 without collapse. Then, when the slide arm 43 returns to the original position,
The drive motor 31b of the elevator 30 is driven to return the table board 34 to the uppermost initial position, and thereafter, this is repeated. The belt conveyor 41 may be moved at all times, or may be moved by a frame feed operation in accordance with the operation of the slide arm 43.

As described above, the thermoformed product trimmed by the die press is transported together with the scrap onto the opening table 20, and the push-in arm is opened from above while the dropping door 23 closing the opening 22a is opened while the intermittent feeding is stopped. At 50, the thermoformed product is pushed under the opening 22a, placed on the table plate 34 of the elevator 30 waiting therebelow, and when a predetermined number of stages are reached, the thermoformed product laminated on the table plate 34 is reached. Belt conveyor 41 of take-out table 40
Because it was moved upward, it was possible to take out the thermoformed product while operating online.
