Disclosure of Invention

Problems to be solved by the invention

Including the apparatus and method disclosed in patent documents 1 and 2, when the fins for the heat exchanger are gathered by fitting the insertion holes of the fins for the heat exchanger into the stacking pins standing vertically on the holder, the fins for the heat exchanger fitted into different stacking pins and adjacent in the horizontal direction are gathered without overlapping each other. However, when the fins for the heat exchanger are gathered from above, the stacking pins come close to each other due to the upward shaking and inclination of the stacking pins, and there is a portion where the fins adjacent in the horizontal direction overlap each other with the gathering. As a result, aggregates may be formed which are aggregated when fins for heat exchangers adjacent in the horizontal direction overlap. Conventionally, when taking out 1 aggregate of fins for a heat exchanger from a stacking apparatus, the stacking apparatus supports the aggregate of fins for a heat exchanger at a lower side, moves the aggregate of fins for a heat exchanger to an upper side including a right upper side together with a stacking pin provided in the stacking apparatus, and then removes the stacking pin to obtain the aggregate of fins. However, when the horizontally adjacent fins are overlapped in the fin aggregate as described above, if the horizontally adjacent fins are moved upward while supporting the fin aggregate, the overlapped portions are caught and the upward movement is not easily performed, which causes a problem that the fins are difficult to be taken out. In order to remove the 1-fin aggregation for the heat exchanger in order to eliminate the sticking, the temporary insertion pin (japanese laid-open needle: reverse insertion hole しピン) may be inclined or the fins may be shaken up and down, but there is a problem that the stacked pins and fins are deformed.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a transfer device that can easily remove an overlap even when the fins for heat exchangers adjacent in the horizontal direction are overlapped to form an aggregate, and can take out the aggregate of the fins for heat exchangers from the aggregate group of the fins for heat exchangers.

Means for solving the problems

In order to achieve the above object, the transfer device of the present invention has the following configuration. That is, the present invention is a transfer apparatus including: an accumulating portion for stacking fins for a heat exchanger; and a moving portion for taking out aggregates from an aggregate group of the fins for the heat exchanger stacked on the aggregation portion, the aggregation portion having: a stacking pin inserted into the insertion hole of the fin for the heat exchanger; a stack pin holder configured to hold the stack pin such that the root of the stack pin can be inserted and extracted, when one end of the stack pin is a tip and the other end is a root; a stacking pin guide plate provided above the stacking pin holder and holding the upper side of the root of the stacking pin; a spacer for a stacking pin guide plate, which abuts against the stacking pin guide plate and is provided at the base portion of the collecting portion; a fin receiving plate for supporting the collected fins for the heat exchanger from below; and a fin receiving plate spacer abutting against the fin receiving plate and provided at the base portion of the collecting portion, the moving portion including: a tip end clamping portion that clamps a tip end portion of the stack pin; a root clamping portion that clamps a root of the stack pin; a top end vertical movement mechanism which vertically moves the top end clamping part; and a forward/backward movement mechanism that moves the tip end clamping portion or the root end clamping portion forward/backward, wherein the tip end clamping portion clamps the tip end portion of the stack pin and then moves the stack pin upward, the stack pin is pulled out from the stack pin holder, and the moving portion is moved in a direction away from the aggregate group in a state where the root end of the stack pin is clamped and the stack pin is inserted into the aggregate, and the aggregate is moved. According to this configuration, even in the case of an aggregate in which the fins for the heat exchanger adjacent in the horizontal direction are stacked, the aggregate can be moved in the horizontal direction for each stacking pin, and the aggregate of the fins for the heat exchanger can be taken out from the aggregate group.

In the present invention, the fin receiving plate spacer has a top position located above a top position of the stacking pin guide plate spacer, and a space is provided between the fin receiving plates adjacent to each other with the stacking pin guide plate interposed therebetween, and a root clamping portion entry region into which the root clamping portion can enter is provided. Thus, the root clamping portion can enter the lower portion of the cluster group of the fins for the heat exchanger to clamp the root of the stacking pin. Even if the aggregates are aggregates that are aggregated when the fins for the heat exchangers adjacent in the horizontal direction are overlapped, the aggregates of the fins for the heat exchangers can be moved in the horizontal direction for each stacking pin and taken out from the fin aggregate group for the heat exchangers.

In the present invention, the moving portion includes a fin support member that supports a lower surface of the heat exchanger fin. This prevents the fins from being deformed when the aggregate is taken out.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the transfer device of the present invention, even in the case of an aggregate in which horizontally adjacent fins for a heat exchanger are overlapped, the overlapping can be easily released, and the aggregate of the fins for the heat exchanger can be taken out from the aggregate group of the fins for the heat exchanger.

The transfer device 10 of the present embodiment includes a collecting unit 12 and a moving unit 14. The collector 12 is a device for stacking the fins 16, and can obtain a collector 18 of the fins 16 by stacking the fins 16 one by one (layer by layer) from above. In this case, when the fins 16 are arranged in parallel in the horizontal direction, a plurality of rows of fins 16 can be arranged in parallel and stacked in the collecting section 12 in the horizontal direction. The moving section 14 is a device for taking out and separating aggregates 18 of 1 or more fins 16 from the aggregate 18 group of the plurality of fins 16 stacked in the accumulating section 12 to obtain 1 or more aggregates 18. In the present embodiment, a case will be described where the collecting portion 12 is provided on a horizontal plane, the fins 16 are collected in the vertical direction, and the plurality of fins 16 are arranged in parallel in the horizontal direction, but the direction of the installation surface of the collecting portion 12, the collecting direction of the fins 16, and the direction of arrangement are not limited.

The 1-piece (1-row) fin 16 has a plurality of flanged insertion holes 20 formed along the longitudinal direction of a thin metal plate such as aluminum. Fig. 1 and 2 show the aggregates 18 in which 1 stacking pin 22 is inserted into each of two insertion holes 20 of the insertion holes 20 of 1 fin 16 and stacked one by one, and fig. 2 shows 4 aggregates 18 in which the fins 16 are stacked in 4 rows and 4 columns. However, the number of insertion holes 20 of 1 fin 16, the number of stacking pins 22 inserted into 1 fin 16, and the number of aggregates 18 of fins 16 aggregated in the aggregation portion 12 in parallel are not limited. In addition, the dot-dash line in fig. 1 indicates the center of the insertion hole 20, fig. 2 shows the aggregates 18 of the fins 16 up to the 4 th row, and the aggregates 18 of the fins 16 in the 5 th row and thereafter are omitted.

The nesting portion 12 has stacking pins 22 and stacking pin retainers 24. The stacking pin 22 has a rod shape with one end portion thereof being tapered, the tapered end portion being a tip portion, and the other end portion being a root portion. The stacking pin holder 24 is disposed below the gathering part 12 at a position to receive the stacking pins 22, and the stacking pin holder 24 holds the stacking pins 22 in a state in which the stacking pins 22 can be pulled out and inserted from the root parts of the stacking pins 22. The stacking pin 22 is vertically erected on the stacking pin holder 24 with its tip end directed upward and its base end directed downward.

The shape of the stack pin holder 24 and the shape of the holding portion of the stack pin holder 24 held by the stack pin holder 24 are not limited, and the stack pin holder 24 may be a flat plate provided with a recess at a position into which the stack pin 22 is inserted. As shown in the drawings, the stack pin holder 24 may have a stack pin holder 26, and the stack pin holder 26 may be arranged such that a cylindrical body capable of surrounding the side circumferential surface of the root portion of the stack pin 22 protrudes from a flat plate provided with a recess, and the stack pin 22 penetrates from the cylindrical body to the recess. The stack pin holder 24 may be configured such that the stack pin holder 26 can set and release the fixed state of the stack pin 22 as needed so that the stack pin 22 can be inserted and extracted. Further, a recess (not shown) provided at the root of the stack pin 22 may engage with a projection (not shown) provided on the inner circumferential surface of the stack pin holder 26 and biased by an elastic member to hold the stack pin 22 in a state in which it can be inserted and removed.

The gathering part 12 has a stacking pin guide plate 28. The stacking pin guide plate 28 is provided above the stacking pin holder 24, and is a member for stably raising the stacking pins 22 and preventing the vertically raised stacking pins 22 from shaking. The stack pin guide plate 28 has a flat plate shape, and a guide plate through hole 30 is provided in the stack pin guide plate 28 as a hole through which the stack pin 22 passes. Below the stacking pin guide plate 28 and between the stacking pin guide plate 28 and the stacking pin holder 24, a stacking pin guide plate spacer 32 for supporting the stacking pin guide plate 28 is provided at the base portion of the accumulating portion 12. At this time, the stacking pin guide plate 28 does not hold the fins 16. In addition, the number of the stack pin guide plates 28 provided is not limited.

The accumulating portion 12 may also have a plate up-down moving mechanism 34. The plate up-down moving mechanism 34 is a device that receives the fins 16 inserted toward the stacking pin 22 and is capable of sequentially lowering a fin receiving plate 36 for receiving the fins 16 while the fins 16 are gathered. The fins 16 are supported from below the fins 16 by fin receiving plates 36. The plate up-down moving mechanism 34 has a lift plate 38, a ball screw 40, and a linear guide 42. The ball screw 40 and the linear guide 42 are vertically provided, and the lifting plate 38 connected to the ball screw 40 is driven by a motor (not shown) and driven by the ball screw, and is vertically movable along the linear guide 42. The fin receiving plate 36 is a flat plate-like member, and is supported from below the fin receiving plate 36 by a lifting plate 38.

As shown in fig. 4, the plate vertical movement mechanism 34 is disposed so as to face each other at the side portions of both the fins 16 and the aggregates 18 with the fins 16 interposed therebetween. Further, below the fin receiving plate 36, a fin receiving plate spacer 44 for supporting the fin receiving plate 36 is provided at the base portion of the collecting section 12. The two plate up-down moving mechanisms 34 support the end portions on the short sides of the fin receiving plates 36 by the mutually opposing elevating plates 38. When the fins 16 are gathered and the fin receiving plate 36 is lowered, the fin receiving plate 36 abuts on the top of the fin receiving plate spacer 44. At this time, the position of the top of the fin receiving plate spacer 44 may be set so that the height of the aggregate 18 from the upper surface of the fin receiving plate 36 to the position where the stacking of the fins 16 is started becomes a desired height, and the stacking of the fins 16 may be set to be stopped.

The top position of the spacer for stack pin guide plates 32 is different from the top position of the spacer for fin receiving plates 44 when viewed in the horizontal direction, and the top position of the spacer for fin receiving plates 44 is located above the top position of the spacer for stack pin guide plates 32. The difference in height between the top positions is defined as h. Further, since the stacking pin guide plate 28 does not hold the fins 16, a space is provided between the fin receiving plates 36 adjacent to each other through the stacking pin guide plate 28. This interval is set to w. h. The size of w is set to a degree that the base clamping portion 48 of the movable portion 14 described later enters, and is set according to the height of the base clamp. A region into which the root portion clamp 48 can enter, which is formed by providing the height difference h and the interval w, is set as a root portion clamp entering region.

The moving unit 14 includes: a tip end clamping portion 46 having a clamping type clamping portion that grips and clamps the tip end portion of the stack pin 22; and a cylinder 47 for operating the clamping portion of the distal end clamping portion. And further has: a root clamping portion 48 having a clamping type clamping portion which grips and clamps the root of the stack pin 22; and a cylinder 49 for operating the clamp portion of the root clamp portion 48. The moving unit 14 further includes: a tip end vertical movement mechanism 50 that vertically moves the tip end holding portion 46; and a forward/backward movement mechanism 52 for moving the tip holding portion 46 or the root holding portion 48 forward/backward. The tip up-down movement mechanism 50 has a cylinder for up-down movement, and the forward-backward movement mechanism 52 has a cylinder for forward-backward movement. As shown in the drawings, the moving part 14 may have a fin support 54. By providing the fin support 54, the fins can be prevented from being deformed when the aggregate 18 is taken out.

The operation of the moving unit 14 will be described. The moving unit 14 may be supported by a robot arm or the like, not shown, so that the entire moving unit 14 can move and rotate. As shown in fig. 8A, first, the moving portion 14 moves in the horizontal direction as a whole, and enters from the front side of the group of aggregates 18 toward the group of aggregates 18. At this time, the grip portion of the distal grip portion 46 and the grip portion of the proximal grip portion 48 are in an open state.

Next, as shown in fig. 8B, the moving portion 14 moves to the front side of the stack pin 22, the root clamping portion 48 enters the root clamping portion entry region, and the tip clamping portion 46 and the root clamping portion 48 move to positions where the stack pin 22 can be clamped. At the same time, the root clamping portion 48 is moved to a position above the stacking pin guide plate 28 and in contact with the lower surface of the collected lowermost fin 16 to support the fin 16, and can support the fin 16. Then, only the clamp portion of the top end clamp portion 46 is closed to clamp the stack pin 22. On the other hand, as shown in the figures, when the fin receiver 54 is provided, the fin receiver 54 can support the fins 16 by moving to a position above the stacking pin guide plate 28 and supporting the lower surfaces of the gathered lowermost fins 16. Then, only the clamp portion of the top end clamp portion 46 is closed to clamp the stack pin 22. The case of having the fin support 54 will be described later.

Next, as shown in fig. 8C, the distal end vertical movement mechanism 50 is operated to raise only the distal end holding portion 46. At this time, since the lowermost end of the aggregation 18 is supported by the fin support 54, only the stack pin 22 can be lifted upward from the stack pin holder 24 that holds the aggregation 18 in a state in which it can be extracted and inserted without changing the position of the aggregation 18 in the vertical direction. Thereby, the stack pin 22 can be pulled out from the stack pin holder 24 and the stack pin guide plate 28.

Subsequently, the clamping portions of the root clamping portions 48 are closed, and as shown in fig. 8D, the entire moving portion 14 moves horizontally in parallel in a direction away from the group of aggregates 18 (toward the front side). This enables only a part of the aggregate 18 to be taken out. Even in the aggregate 18 in which the fins 16 adjacent to each other in the horizontal direction are overlapped with each other, the aggregation 18 of the fins 16 for the heat exchanger can be easily removed by removing the overlapping.

In fig. 8D, the direction in which the moving portion 14 is separated from the group of aggregates 18 is the horizontal direction, but the present invention is not limited thereto. The direction in which the moving portion 14 is separated from the group of aggregates 18 may be a vertical direction perpendicular to the collection direction of the group of aggregates 18 or a direction inclined from the vertical direction toward the collection direction, and may be a direction in which the fins 16 adjacent to each other in the horizontal direction can be released from overlapping each other.

The number of the stack pins 22 gripped and gripped by the clamp-type gripping portion of the tip gripping portion 46 and the root gripping portion 48 is not limited, and only 1 or a plurality of stack pins 18 may be gripped to take out only 1 aggregate 18 or a plurality of arrays of aggregates 18.

The operation of the moving section 14 when the stacking pins 22 are pulled out will be described. As shown in fig. 9A, subsequent to fig. 8D, before the stack pins 22 are extracted, the stack pins 22 are held, and the aggregates 18 are horizontally placed on the horizontal surface of the table 56 or the like while maintaining the stack.

Next, as shown in fig. 9B, in a state where the grip portion of the root grip portion 48 is opened, the forward/backward movement mechanism 52 of the root grip portion 48 is operated to move the root grip portion 48 in a backward direction (upward in fig. 9).

Next, as shown in fig. 9C, the entire moving portion 14 is moved in parallel in the direction in which the tip of the stack pin 22 is located, and a state is set in which the stack pin 22 is partially inserted from the aggregation 18. At this time, the root clamping portion 48 is moved to a position above (rightward in fig. 9) the fin 16 originally located on the uppermost surface of the aggregate 18.

Next, as shown in fig. 9D, in a state where the grip portion of the root grip portion 48 is opened, the forward/backward movement mechanism 52 of the root grip portion 48 is operated to move the root grip portion 48 in the forward direction (downward direction in fig. 9). Then, the root holding portion 48 is closed to hold the stack pin 22, and the stack pin 22 is extracted from the aggregation 18.

In addition, a stopper 60 may also be provided to prevent the fins 16 from moving when the stacking pin 22 is extracted. Stopper 60 is provided on table 56 at a position above (to the right of) fin 16 originally on the uppermost surface of aggregate 18. The aggregate may be placed on the table 56 from above together with the stacking pins 22 and the stacking pins 22 may be placed in the grooves in a U-shaped groove.

Fig. 9C shows a case where the stack pin is extracted by moving the stack pin to a position above (rightward in fig. 9) the fin 16 originally located on the uppermost surface of the aggregate 18, but the stack pin may be extracted to a position below (leftward in fig. 9) the fin 16 originally located on the lowermost surface of the aggregate 18. In this case, the forward/backward movement mechanism 52 of the base-end clamping portion 48 is not operated, but the forward/backward movement mechanism 52 of the tip-end clamping portion 46 is operated with the stack pin 22 clamped by the base-end clamping portion 48, so that the stack pin 22 is released or clamped and the stack pin 22 is extracted from the aggregation 18.

Before and after the stack pins 22 are pulled out from the aggregates 18 and the tubes for the heat exchanger are inserted into the insertion holes 20 of the fins 16, temporary insertion pins 58 may be provided to previously maintain and fix the stack of the aggregates 18. The insertion and extraction of the temporary insertion pins 58 with respect to the conglomerates 18 can also be carried out manually.

Further, a flat car may be provided in which wheels are provided below the stacking unit 12 and the stacking unit 12 is placed on the top plate.
