Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, when a work is taken out from a pallet in which a work is housed between a plurality of partition members arranged at predetermined intervals, the partition member is raised to raise the pallet partition to enable the work to be taken out. It relates to the device.

[0002]

[Prior Art]

 Generally, in a production line, a substantially flat plate-like component (workpiece) such as a side plate of a car body is loaded into a line in a state of being stored in a pallet, and when assembling the work, the work is sequentially loaded from the pallet one by one. It is taken out and transferred to the assembly position. In this case, a plurality of partition members are arranged in the pallet in the widthwise direction at predetermined intervals, and the above-mentioned works are accommodated between the respective partition members while standing up, while the work from the pallet is accommodated. The work loader equipped with the scooping claws is used to take out a plurality of works stored in the pallet one by one from the end side by the scooping claws. As this type of work loader, for example, there is one disclosed in Japanese Patent Laid-Open No. 193889/1983.

By the way, the partitioning member separates the works adjacent to each other in a state of being housed in the pallet to prevent damage due to mutual interference of these works. It is necessary to remove this as it becomes an obstacle. For this reason, this partition member is generally formed in the shape of a lever that can be swung in the vertical direction, and is configured so that the required partitioning action is provided at the lower position and the partitioning action is released at the upper position. When taking out, it is customary to interlock with the operation of the work loader to raise the partition member by an appropriate partition raising device to move it from the lower position to the upper position.

[0004]

However, in the conventional partitioning and raising device, a lever having an abutting portion for the partitioning member formed at the tip thereof is integrally formed, and the lever is simply swung in the vertical direction. Since the partition member is raised by making the contact portion, there are the following problems.

That is, when the partition member is raised by the lever, it is most desirable for the partition member to contact the contact portion of the lever in a direction orthogonal to the plane direction in terms of transmission of the operating force. However, if the partition raising device is composed of a simple lever, the plane direction of the contact portion formed at the tip of the lever continuously changes as the lever swings, and the work to which the lever is attached is changed. Since the setting position of the loader is governed by the type of work to be taken out (that is, the shape and dimension), the relative position between the lever and the partition member fixedly arranged on the pallet side also changes depending on the type of work. It is difficult to always bring the partition member into contact with the contact portion of the lever from the direction orthogonal to the plane direction thereof, and therefore it is considered that the certainty of the work cannot be ensured.

Therefore, the present invention has been made as a provision of a partition erection device for a pallet that has a simple structure and is capable of reliably performing the operation of raising the partition member.

[0007]

[Means for Solving the Problems]

 In the present invention, as a concrete means for solving such a problem, it is capable of rotating in the vertical direction and selectively set in two positions, an operating position rotated downward and a release position rotated upward. A pallet in which a plurality of partition members are arranged side by side at a predetermined interval. The pallet is installed in a work loader that is housed between the partition members and that sequentially removes the works that are partitioned by the partition members in the operating position. In a pallet partitioning and raising device that raises the partitioning member from its operating position to its release position when a work is taken out by the work loader, the pallet is rotatably supported by the first support shaft in the vertical direction and appropriately Arm swung by the driving means, a first pulley fixedly arranged in a non-rotating state coaxially with the first support shaft, and the first pulley. A belt stretched between a first pulley that has the same diameter and is rotatably attached to the swing end side of the arm around an axis parallel to the first support shaft, and with respect to the second pulley. And a raising member fixedly arranged.

[0008]

[Action]

 According to the present invention, with such a configuration, the following operation can be obtained. That is, the arm is swung by the driving means when the work is taken out from the pallet. Then, the first pulley arranged coaxially with the first support shaft, which is the swing fulcrum of the arm, is fixed and does not rotate, but the second pulley arranged on the swing end side of the arm is rotatable. Therefore, in the belt stretched between these two pulleys, the winding position on the first pulley side changes with the swing displacement of the arm and the belt stretched on the second pulley side. Means that the vehicle travels by an amount corresponding to the amount of change in the winding position on the first pulley side, and as a result the second pulley is rotated, and the rotation amount is the same for each pulley. Since the diameter is set, the rotation amount corresponds to the arm swing angle. Therefore, the raising member fixed to the second pulley side maintains the same posture regardless of the swing angle of the arm. For example, the assembling position of the raising member to the second pulley is horizontal. If the initial setting is made to the state, the raising member will move vertically in parallel with the swing of the arm while always maintaining the horizontal state.

[0009]

[Effect of the device]

 Therefore, according to the pallet partitioning and raising device of the present invention, since the raising member always moves in parallel in the vertical direction while the arm is rocked, the raising member is attached to the pallet. If the direction is initially set to the horizontal position, regardless of the change in the relative position of the partition raising device and the partition member and the change in the swing angle of the arm or the partition member during the raising operation of the partition member, The partitioning member can be brought into contact with the supporting member in a direction orthogonal to the plane direction, which improves the transmission of the operating force and improves the certainty of work in raising the partitioning member. This is a practical effect that can be obtained.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1A shows a main part of a work loader Z including a partition raising device X according to an embodiment of the present invention. The work loader Z takes out a work 50 (a side plate which is a constituent member of an automobile body in this embodiment) housed in a pallet 1 described later, and conveys the work 50 to an assembly line. When the work 50 is taken out from the pallet 1, the partitioning member 7 which will be described later is raised to enable the work taking-out work. For convenience of explanation, the structure of the pallet 1 will be described first. After that, the configurations of the work loader Z and the partition raising device X will be described in detail.

.. Pallet 1 FIG. 3 shows a pallet 1 for accommodating a plurality of substantially flat plate-like works 50, 50, ... This pallet 1 has a pair of front struts 3 and 3 standing on both ends of a front end of a rectangular plate 2 having a predetermined size, and a pair of rear struts 4 and 4 standing on both ends of a rear end. A front side work receiving member 5 and a rear side work receiving portion 6 which are respectively constituted by inclined plates are fixed at positions near the front end portion and rear end portion of the substrate 2 in the width direction of the substrate 2. .. The work 50 is held in a state where the front lower end portion 50a is supported by the front work receiving member 5 and the rear lower end portion 50b is supported by the rear work receiving portion 6, respectively.

However, if the respective works 50, 50, ... Are simply supported by the front work receiving member 5 and the rear work receiving portion 6 as described above, the respective works 50, 50 ,. There is a risk that adjacent objects may come into contact with each other and be damaged. Therefore, partition members 7 to be described later are arranged at predetermined positions in the width direction of the substrate 2 at the upper positions of the front support columns 3, 3, and the respective work members 50, 50, ... By the partition members 7, 7 ,. The partitions are separated from each other to prevent mutual contact and also prevent the workpieces 50, 50, ... from falling down.

The partition member 7 will be described with reference to FIGS. 2 and 3. One end of an arm portion 8 of a predetermined length formed into a substantially L-shape is formed between the front support columns 3 and 3. The partition member support shaft 10 is arranged so as to be swingably supported, while the other end (swing end) is provided with a partition portion 9 made of a plate body of a predetermined size. Further, the partition member 7 is restricted in its maximum swinging position downward by the first restricting member 11 arranged between the front columns 3 as shown by the solid line in FIG. As shown by the chain line, the maximum rocking position in the upper direction is restricted by the second restricting member 12 arranged outside of the first restricting member 11.

Then, when the partition member 7 is swing-regulated by the first restricting member 11, the partition portion 9 is overlapped with the front upper part 50c of the work 50 by an appropriate amount, whereby the work 50 is formed. Of the workpiece 50 is prevented and mutual interference with the adjacent work 50 is prevented (hereinafter, the position of the partition member 7 at this time is referred to as an operating position). On the other hand, when the partition member 7 is swing-controlled by the second restricting member 12, the partition portion 9 is largely retracted upward from the work 50 to allow the work 50 to be taken out (hereinafter, referred to as "workpiece 50"). The position of the partition member 7 at this time is called a release position). The partition member 7 is moved from the operating position to the releasing position by the partition raising device X described later.

In this embodiment, a plurality of (nine in this embodiment) partition members 7 having the above-described structure are arranged at predetermined intervals in the axial direction of the partition member support shaft 10. The work pieces 50, 50, ... Are housed between the partition members 7, 7, ..

Work loader Z The work loader Z takes out a plurality of works 50, 50, ... Stored on the pallet 1 in that order from the end of the plurality of works 50, 50 ,. As shown in FIG. 1A, it has a girder member 16 fixed to the lower end of the movable column 15 in the lateral direction. The movable support column 15 is supported by a moving mechanism (not shown), and is movable in the up-down direction (arrow AB direction), the front-back direction (arrow CD-D direction), and the left-right direction (arrow E-F direction). ing.

An elevating girder 18 is attached to a lower side of the girder member 16 while being guided by a pair of left and right guide rods 17, 17, and the elevating girder 18 is attached to the girder member 16 by an elevating cylinder 19. On the other hand, it can move relative to the vertical direction. Further, work scooping claws 20 each having a tip end thereof as a work receiving portion 21 are fixed to both left and right ends of the lifting girder 18 while extending forward from the lifting girder 18. Further, a work pressing member 22 extending upward and downward is provided in the vicinity of the work receiving portion 21 of each work scooping claw 20.

When the work loader Z configured as described above is used to take out the work 50 from the pallet 1, as shown in FIG. 1A, the girder member 16 is moved by a moving mechanism (not shown), and the above-mentioned respective members are moved. The work receiving portions 21, 21 of the work scooping claws 20, 20 are positioned in the openings 51, 52 of the work 50 accommodated in the pallet 1, respectively. After that, the elevating cylinder 18 is moved up by the elevating cylinder 19 so that the work receiving portions 21, 21 of the work scooping claws 20, 20 are engaged with the openings 51, 52 from the lower side, and the work is lifted. The pallet 1 is separated from the substrate 2 side and is conveyed to a predetermined assembly line by the moving mechanism.

In this case, when the work 50 is supported by the work scooping claws 20, 20, the partition member 7 is set to the operating position. Therefore, at this time, it is necessary to operate the partition raising device X, which will be described later, to raise the partition member 7 from the operating position to the release position side to allow the work 50 to be taken out. The partition raising device X, which is the gist of the present invention, will be described below.

Partition raising device X The partition raising device X will be described with reference to FIGS. 1A, 1B and 2, and a supporting base material extending in the vertical direction at one end of the lifting girder 18 of the work loader Z. An arm 35 having a predetermined length is supported by a first support shaft 33 so that one end of the bracket 31 provided on the bracket 30 can be vertically swung. The arm 35 is made to swing vertically by the expansion and contraction movement of the cylinder 40 (corresponding to the driving means in the scope of the utility model registration claim) attached to the bracket 32 provided on the supporting base material 30. It has become.

On the other hand, a second support shaft 34 extending in parallel with the first support shaft 33 is rotatably supported at the other end (swing end) of the arm 35, and the second support shaft 34 has a second support shaft 34. A strip-plate-shaped raising member 39 for abutting against the partition portion 9 of the partition member 7 and swinging the partition portion 9 is fixed to the end portion in a state of extending forward.

Further, a first pulley 37 is attached to the first support shaft 33, and a second pulley 38 having the same diameter as the first pulley 37 is attached to the second support shaft 34. Then, of the two pulleys 37, 38, the first pulley 37 is set in a non-rotating state (for example, when the first support shaft 33 is supported by the bracket 31 in a non-rotating state). It is fixed to the first support shaft 33, and is fixed to the bracket 31 side when the first support shaft 33 is rotatably supported with respect to the bracket 31). On the other hand, the second pulley 38 is fixed to the second support shaft 34 rotatably supported on the arm 35 in a non-rotating state.

A belt 36, which is a timing belt with a claw, is stretched over the pair of pulleys 37, 38 whose mounting states are set as described above. When the arm 35 is swung while the belt 36 is stretched in this manner, the winding position of the belt 36 around the first pulley 37 on the first pulley 37 side is accompanied by the swing of the arm 35. Change. The amount of change in the winding position of the belt 36 on the side of the first pulley 37 is represented as the running amount of the belt 36 on the side of the second pulley 38, and the second pulley 38 moves the arm 35 at an angle corresponding to this running amount. It will rotate relative to. In this case, since the change amount of the winding position of the belt 36 on the first pulley 37 is equal to the running amount of the belt 36 on the second pulley 38, the belt 36 constitutes a so-called parallel link. The second pulley 38 is displaced vertically while drawing an arc as the arm 35 swings, but the rotational position is always maintained constant. Therefore, when the position of the second pulley 38 in the rotational direction is initially set so that the upper surface of the raising member 39 is horizontal when the belt 36 is stretched, thereafter, regardless of the swing of the arm 35, The raising member 39 will always maintain a horizontal state (see FIG. 2).

According to the partition raising device X configured as described above, as shown in FIG. 2, the arm 35 is swung to cause the raising member 39 to operate the predetermined partition member 7 on the pallet 1 side. When the raising member 39 is raised from the position to the release position, the raising member 39 always maintains a horizontal state during its swinging. Therefore, for example, the type of the work 50 is different, and accordingly, the set position of the work loader Z, that is, The position of the first support shaft 33 of the partition raising device X is displaced in the vertical direction, so that the arm 35 swings when the raising member 39 comes into contact with the partition portion 9 of the partition member 7 in the operating position. Even if the angle changes, the partitioning portion 9 of the partitioning member 7 is always brought into contact with the raising member 39 from a direction orthogonal to the plane direction thereof without being affected by this. The raising action of the partition member 7 by the bending member 39 is appropriately performed under the optimum operating force transmission state, and the operating reliability of the partition raising device X is enhanced accordingly.
