Disclosure of Invention
Problems to be solved by the invention
The clamping device shown in patent document 1 grips 1 drill rod with two opposing gripping portions. A common clamping device holds and clamps the rod-like objects one by one. In the case of a gathering device for gathering fins for heat exchangers, a plurality of rows of fins for heat exchangers are arranged in parallel by using a plurality of stacking pins, and a plurality of fins for heat exchangers are gathered in each row. Then, in a state where the stacking pins are inserted into the aggregate, the stacking pins are caught by the aggregate group of the heat exchanger fins in which a plurality of heat exchanger fins are individually aggregated in each row, and the aggregate is taken out. When the operation of taking out the aggregate into which the stacking pins are inserted from the aggregate group is performed, the operation of gripping the stacking pins is performed. In addition to the operation of standing the stacking pin on the collecting device and taking out the stacking pin from the aggregate, the operation of gripping the rod is also performed in the operation of inserting and taking out the temporary insertion pin (japanese laid-open: insertion hole しピン) for maintaining the stack of the aggregate into and from the insertion hole of the fin for the heat exchanger. In such an operation of grasping the rod-like object, in particular, when the aggregate into which the rod-like object is inserted is taken out from the aggregate group, it takes time to take out the aggregate every 1 line, and the efficiency is poor.
Fig. 5 shows a conventional bar holding device, and shows a clamp portion 72A and another clamp portion 72B, and concave grooves 741 and 742 are formed in the clamp portion 72A so as to hold two conventional bars 701 and 702. The rod does not necessarily have a constant diameter, and when the clamp portion 72B abuts against the rod 701, a gap may be formed between the clamp portion 72B and the other rod 702. Thus, there are the following problems: two rods cannot be held between them, and even if they come into contact with the rods, they cannot be held and gripped with a uniform force, and two rows of aggregates cannot be simultaneously taken out by 1 taking-out operation.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a rod clamp device capable of simultaneously clamping two rods inserted into insertion holes of fins for a heat exchanger.
Means for solving the problems
In order to achieve the above object, the rod clamp device according to the present invention has the following configuration. That is, the present invention is a rod clamp device for clamping a rod inserted into an insertion hole of a fin for a heat exchanger, characterized in that the stick-shaped object clamping device is provided with a 1 st clamping part and a 2 nd clamping part, the 1 st clamping part and the 2 nd clamping part are set to be capable of relatively performing contact and separation movement, the 1 st clamping part is formed with two concave parts which can respectively receive the 1 st rod-shaped object and the 2 nd rod-shaped object, the 2 nd clamping part is arranged on the opening side of the concave part of the 1 st clamping part and is provided with a clamping part for clamping the rod-shaped object between the 2 nd clamping part and the 1 st clamping part, the gripping part of the 2 nd gripping part is pivotally supported by a pivot shaft arranged in a direction parallel to the axial direction of the rod, when the rod-shaped object is clamped, the clamping part rotates, and the rod-shaped object is clamped between the 2 nd clamping part and the 1 st clamping part. According to this configuration, two rods can be sandwiched, two rows of aggregates can be simultaneously taken out, and the aggregates can be efficiently taken out.
In the present invention, the pivot shaft is located between a gripping position for the rod 1 and a gripping position for the rod 2. Thus, two rods can be gripped simultaneously with more uniform force, and two rows of aggregates can be taken out from the aggregate group of fins by 1 taking-out operation.
In the present invention, the rods are arranged in a staggered state with respect to the direction along the longitudinal direction of the fin, and the gripping position of the 1 st gripper and the gripping position of the 2 nd gripper are different in the left-right position between the 1 st rod and the 2 nd rod. Thus, the two rod-like objects arranged in the staggered state can be gripped with a uniform force, and the two rows of aggregates can be taken out.
In the present invention, the 2 nd clamp portion has a shaft support portion provided with the rotation shaft, and the shaft support portion is provided with a plurality of stoppers provided so as to protrude toward a gap between the clamp portion and the shaft support portion. Thus, even when only 1 line of aggregates is taken out, 1 rod can be held between them.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the rod-like object clamping device of the present invention, two rod-like objects inserted into the insertion holes of the fins for the heat exchanger can be clamped at the same time.

Detailed Description
An example of the rod gripper 10 according to the present embodiment will be described below with reference to the drawings. Hereinafter, the fin 14 for the heat exchanger may be referred to as a fin 14. Fig. 1 shows a part of the transfer device 18, and shows a side view of the aggregates 16 of the fins 14 for heat exchangers accumulated in the accumulation device 20 and the transfer device 22. Fig. 2 is a plan view showing the fins 14 for the heat exchanger gathered in the gathering device 20, the gathering bodies 16 of the fins 14, and the moving device 22. The root holding portion 32 (or the tip holding portion 28) has two portions on the left and right, and each holds two rods 12. Fig. 3 is a front view of the collector 16 and the moving device 22 collected to the fins 14 for the heat exchanger of the collector 20. An enlarged view of the clamping portions 32A, 32B of one of the two root clamps 32 shown in fig. 2 is shown in fig. 4. Fig. 4A shows a state in which the rod 12 is not sandwiched, fig. 4B shows a state in which one of the two rods 12 is sandwiched, and fig. 4C shows a state in which the rod 12 is sandwiched.
The rod-like object holding apparatus 10 of the present embodiment has the clamp portions 32A, 32B used for holding the rod- like objects 12, 44 in the manufacture of the heat exchanger, and the rod-like object holding apparatus 10 is used in the transfer device 18 for obtaining the aggregates 16 of the fins 14 for the heat exchanger.
The transfer device 18 for obtaining the aggregates 16 of the fins 14 for the heat exchanger includes an aggregation device 20 and a transfer device 22. The agglomerating device 20 is a device for stacking the fins 14, and the fins 14 are stacked one by one (layer by layer) from above, and agglomerates 16 of the fins 14 can be obtained. In this case, when the fins 14 are arranged in the horizontal direction, the fins 14 are arranged in a plurality of rows in the horizontal direction and stacked in the stacking device 20. The moving device 22 is a device capable of taking out and separating the aggregates 16 of two fins 14 from the aggregate 16 group of the plurality of fins 14 stacked in the aggregation device 20 to obtain two aggregates 16. In the present embodiment, the following case is explained: the collecting device 20 is provided on a horizontal surface, the fins 14 are collected in a vertical direction, and the plurality of fins 14 are arranged in parallel in the horizontal direction, but the direction of the installation surface of the collecting device 20, the collecting direction of the fins 14, and the direction of arrangement are not limited.
The rod- like objects 12 and 44 used in the present embodiment are, for example, stacked pins 12 inserted into insertion holes 24 formed in the fins 14. As will be described later, the fin 14 further includes a temporary insertion pin 44 inserted into the insertion hole 24 formed in the fin. In the present embodiment, as an example of the rod- like objects 12 and 44, a case where two stacking pins 12 are sandwiched and a case where two rows of aggregates 16 are simultaneously extracted from the aggregated group 16 of fins 14, which is formed by aggregating the fins 14 by 1 extracting operation, are mainly described. However, as will be described later, the rod clamp device 10 can clamp 1 rod 12 or 44.
The 1-piece (1-row) fin 14 has a plurality of insertion holes 24 with flanges formed along the longitudinal direction of a thin metal plate such as aluminum. Fig. 2 and 3 show a collective 16 in which 1 stacking pin 12 is inserted into each of two insertion holes 24 of 1 fin 14 and the fins 14 are stacked one by one, and fig. 2 shows 4 collective 16 in which the fins 14 are stacked in 4 rows and 4 columns. However, the number of insertion holes 24 of 1 fin 14, the number of stacking pins 12 inserted into 1 fin 14, and the number of aggregates 16 of fins 14 stacked in parallel in the aggregation device 20 and aggregated are not limited. In fig. 2, the dot-dash line in fig. 3 shows the center of the insertion hole 24, the aggregates 16 of the fins 14 up to the 4 th row are shown, and the aggregates 16 of the fins 14 in the 5 th row and thereafter are omitted.
The transfer device 22 takes out the two aggregates 16 of the 1 st column and the 2 nd column from the aggregate 16 group from the front side with respect to the taking-out direction. Fig. 2 shows a state in which the stacking pins 12 in the 1 st and 2 nd rows and the 1 st and 2 nd rows (including the 3 rd and 4 th rows) are arranged in a staggered state from the front side with respect to the removal direction. However, the arrangement of the stacking pins 12 is not limited, and the stacking pins 12 in the 1 st and 2 nd rows may be arranged in a straight line in parallel with the removal direction.
The nesting device 20 has a stacking pin 12 and a stacking pin retainer 26. The stacking pin 12 is a rod-shaped object with one end portion thereof being tapered, and the tapered end portion is a tip end portion and the other end portion is a root portion. The stacking pin holder 26 is disposed below the stacker device 20 at a position to receive the stacking pins 12, and the stacking pin holder 26 holds the stacking pins 12 in a state in which the stacking pins 12 can be pulled out and inserted from the root portions of the stacking pins 12. The stacking pin 12 is vertically erected on the stacking pin holder 26 with its tip end directed upward and its base end directed downward. As shown in the drawings, the stacking pins 12 have a circular cross section, and the stacking pins 12 are circular rods, but the stacking pins are not limited thereto and may be square rods.
The moving device 22 includes a rod gripper 10, and the rod gripper 10 includes: a tip end clamping portion 28 having a clamping portion that clamps the tip end portion of the stack pin 12; and a cylinder 30 for moving the tip holding portion 28. The stick clamp 10 further includes: a root clamping portion 32 having clamping portions 32A, 32B that clamp the root of the stack pin 12; and a cylinder 34 for moving the root grip 32.
The clamp portions of the distal end clamp portion 28 and the root clamp portion 32 may have the same shape, and as shown in fig. 2, the clamp portions of the distal end clamp portion 28 and the root clamp portion 32 can clamp two stack pins 12 of the 1 st row and the 2 nd row from the front side as the removal direction. The clamp portions 32A and 32B of the root clamp portion 32 will be described later, but the clamp portions can also be applied to the tip clamp portion 28. The root clamping portion 32 has a pair of clamping portions 32A, 32B, and can stably clamp two stack pins 12, i.e., the 1 st stack pin 121 in the 1 st row and the 2 nd stack pin 122 in the 2 nd row, from the front side at the clamping position of the pair of clamping portions 32A, 32B.
Either one of the two clamping portions 32A, 32B is formed with two recesses 381, 382 at its clamping position. The clamp portion formed with the recesses 381, 382 is defined as a 1 st clamp portion 32A. The illustrated recesses 381, 382 are groove-shaped recesses 381, 382 parallel to the vertical direction, which is the standing direction of the stack pin 12. The 1 st stacking pin 121 abuts against both faces in the recess 381. Likewise, the 2 nd stacking pin 122 abuts against both faces within the recess 381. Since the recesses 381, 382 are formed, the position of the stack pin 12 does not move during the stack pin 12 is clamped, and the stack pin 12 is stably clamped in such a manner as to grasp the stack pin 12.
Either one of the two clamp portions 32A, 32B is rotatable about the rotation shaft 36. This clamp portion is referred to as a 2 nd clamp portion 32B. The 2 nd clamping portion 32B is disposed on the opening side of the recessed portions 381, 382 of the 1 st clamping portion 32A, and the 2 nd clamping portion 32B has a clamping portion 321 that clamps the stack pin 12 between itself and the 1 st clamping portion 32A. The 1 st and 2 nd clamp portions 32A and 32B are configured as follows: either one or both of them can be moved to make the contact and separation movement relatively.
When the stacking pin 12 is a round bar, the clamping portion 321 of the 2 nd clamping portion 32B may be formed in a shape having flat surfaces 401 and 402 at the clamping position of the 2 nd clamping portion 32B, or may be flat surfaces 401 and 402 perpendicular to the longitudinal direction of the fin 14. When the stack pin 12 is a square bar, the clamping portion 321 of the 2 nd clamping portion 32B may be formed in a shape having a semi-cylindrical (fish cake-shaped) surface which is curved in a plan view at the clamping position of the 2 nd clamping portion 32B. In any case, the stack pin 12 is in line contact with the 2 nd clamping portion 32B (point contact in a plan view). In this way, the shape of the clamping position of the pair of clamping portions 32A, 32B differs depending on the shape of the vertically arranged stacking pin 12, and may vary depending on the shape of the vertically arranged stacking pin 12.
The 2 nd clamping portion 32B has a clamping portion 321 and a shaft support portion 322. The clamping portion 321 is pivotally supported by a pivot shaft 36 provided on the shaft support portion 322. The rotation shaft 36 is parallel to the axial direction (standing direction) of the stacking pins 12 and is positioned in the vertical direction. The clamping portion 321 does not abut against the shaft support portion 322, and a gap is provided between the clamping portion 321 and the shaft support portion 322 so as to be rotatable, and the clamping portion rotates in a horizontal plane. This allows two stacking pins 12 to be sandwiched therebetween, and two rows of aggregates 16 to be simultaneously taken out by 1 taking-out operation.
The rotation shaft 36 on the 2 nd clamping portion 32B side is located between the clamping positions of the 1 st stack pin 121 and the 2 nd stack pin 122. The distance between the 1 st stacking pin 121 and the 2 nd stacking pin 122 is a distance between the pins in a direction perpendicular to the longitudinal direction of the fins 14 inserted into the two stacking pins 12 and arranged in parallel. The rotating shaft 36 is located between the two stacking pins 121, 122 when viewed in the longitudinal direction.
The 1 st clamp portion 32A and the 2 nd clamp portion 32B move in a direction to approach each other, and are in a state where either one of the two stack pins 12 is clamped and the other stack pin 12 is not clamped. When the 1 st and 2 nd clamping portions 32A and 32B move in the direction of approaching each other, the clamping portion 321 rotates in the direction of clamping the unclamped stack pin 12 around the rotation shaft 36. Thereby, the two stack pins 12 can be sandwiched.
The operation of the rod gripper 10 will be described. Before the stack pin 12 is clamped, the pair of clamping portions 32A, 32B of the root clamping portion 32 is in the state of fig. 4A. Then, the pair of clamp portions 32A, 32B respectively approach the stack pin 12, or either one approaches the stack pin 12. As shown in fig. 4B, when the stack pin 12 abuts on one surface, i.e., the flat surface 401, a gap is generated between the other flat surface 402, with which the stack pin 12 does not abut, and the stack pin 12. When the pair of clamps 32A and 32B are moved in the direction to approach the stack pin 12, the clamp 321 is rotated while being in contact with the stack pin 121, and the state shown in fig. 4C is obtained. The flat surface 402 on the side having a gap with the clamping portion 321 is close to the stack pin 122, and the flat surfaces 401 and 402 come into contact with the two stack pins 121 and 122. Thus, the two stacking pins 12 can be gripped with equal force, and the two rows of the aggregates 16 can be simultaneously extracted from the aggregate 16 group of the fins 14 by 1 extraction operation.
In the drawings, since the stack pins 12 are arranged in a staggered state, the clamping position of the 1 st clamping portion 32A and the clamping position of the 2 nd clamping portion 32B are different between the left and right positions of the 1 st stack pin 121 and the 2 nd stack pin 122. The difference in the left-right positions of the clamping positions in the clamping portions 32A, 32B corresponds to the difference in the positions of the stack pins 12 arranged in the staggered state in the direction along the longitudinal direction of the fins 14. Further, a stepped portion in a plan view, which is engaged with each other when the clamp portions 32A and 32B are brought close to each other, may be provided between the clamping position of the 1 st stacking pin 121 and the clamping position of the 2 nd stacking pin 122.
In addition, when the arrangement of the stack pins 12 is not staggered, but the 1 st and 2 nd rows, that is, the 1 st and 2 nd stack pins 121 and 122 are arranged on a straight line parallel to the removal direction, the step portion in the plan view may not be provided without providing a difference in the left-right position.
The plurality of stoppers 42 and 42 may be provided on the shaft support portion 322 so that the plurality of stoppers 42 and 42 protrude into a gap between the clamping portion 321 and the shaft support portion 322. The clamping portion 321 is disposed so as to abut against any one of the stoppers 42 when rotated to the near side or the deep side. The two stoppers 42 and 42 may be disposed at positions facing the clamping portion 321 via the rotating shaft 36. One stopper 42 is positioned parallel to the plane 401 with which the 1 st stacking pin 121 abuts and abuts against the surface facing the shaft support portion 322, and the other stopper 42 is positioned parallel to the plane 402 with which the 2 nd stacking pin 122 abuts and abuts against the surface facing the shaft support portion 322. By providing this stopper 42, when the 2 nd stacking pin 122 is not provided and 1 row of aggregates 16 is taken out, even if there are only 1 stacking pin 121, the stacking pins 121 can be held.
As another example of the rod-like object 12 used in the present embodiment, there is a temporary insertion pin 44 inserted into the insertion hole 24 formed in the fin 14. The temporary insertion pins 44 are used to hold the aggregate 16 in a stack and fix it in advance before and after the tubes for the heat exchanger and the like are inserted into the insertion holes 24 of the fins 14.
