This paper relates to a pallet changer, in particular the displacement obtained by lifting and lowering along the cam hole of the side plate the feed roller of the operating plate, which is hinged to the top plate of the platform by the lifting motion of the rack engaged with the pinion rotated by the motor. The pallet is clamped and unclamped by rotating the operating plate by a car, and then the pallet is located on the lower side of the loaded pallet and can be continuously placed on the conveyor.The pallet is separated by precise mechanical operation. It is possible to separate the fine and stable pallet and to perform the quick pallet removal automatically, thereby maximizing the work efficiency and reducing the manufacturing cost of the pallet changer.

A pallet separating apparatus of a pallet changer, which is put into an assembly line or the like containing conventional electronic products, is shown in FIG. 1.

The above structure includes a third cylinder 3 coupling the locking piece 4 to the piston,

A second cylinder 2 for elevating the third cylinder 3 within a short range;

The 1st cylinder 1 for raising and lowering the said 2nd cylinder 2 and the 3rd cylinder 3 within the range of distance is comprised.

Referring to the operation according to the conventional configuration as described above are as follows.

First, as shown in Fig. 1 (a), the engaging pieces 4 of the third cylinder 3 are positioned with a plurality of pallets 5 mounted thereon.

As described above, the third cylinder 3 is lowered by a predetermined distance by the operation of the first cylinder 1 and the second cylinder 2 in the state where the pallet 5 is loaded on the locking piece 4, and is also caught. The piece 4 and the pallets 5 seated thereon also stop at a position close to the conveyor by lowering a predetermined distance as shown in FIG.

Then, as shown in FIG. 1 (c), the third cylinder 3 is operated to reverse the locking piece 4.

Accordingly, the pallets 5 are in a state of being seated on the conveyor by retracting the locking piece 4.

In addition, when the locking piece 4 is completed in the reverse direction, the second cylinder 2 is operated to move the third cylinder 3 upwards.

As shown in FIG. 1 (d), the movement distance of the third cylinder 3 is moved to the flange position of the second pallet 5 superimposed on the pallet 5 seated on the conveyor.

Then, when the second cylinder 2 is stopped, the third cylinder 3 is operated to advance the locking piece 4 to the bottom surface of the flange of the second pallet 5 as shown in FIG.

In addition, when the third cylinder (3) is stopped, the first cylinder (1) is operated while the second cylinder (2), the third cylinder (3), the engaging piece (4) and the second pallet (5) and the load thereon The pallets 5 are moved upward as shown in Fig. 1 (f).

Therefore, since the second pallet 5 and the pallet 5 loaded thereon are completely separated from the first pallet 1 seated on the conveyor, the conveyor is rotated to transfer the first pallet 5 to the next process. Let's go.

In addition, when the first cylinder 1 is stopped, the same pallet as described above is continuously repeated, and the loaded pallets 5 are separated one by one and placed on the conveyor.

However, the conventional pallet separating apparatus has some problems.

That is, since the pallet separating apparatus separates the pallets 5 by using a plurality of pneumatic cylinders (1) (2) and (3), an operation imbalance occurs due to the pressure difference of the compressed air supplied from the compressor. do.

Therefore, due to the imbalance as described above, the pistons of the cylinder are not moved exactly by the set distance and an error occurs, causing frequent malfunctions, thereby lowering work efficiency and efficiency.

In addition, the cylinders (1, 2) (3) of the plurality (6 on both sides) have a very expensive price because the production cost is also very expensive.

The purpose of this article to solve and complement these conventional problems,

By separating the pallets by precise mechanical operation, it becomes possible to separate the fine and stable pallets and to perform the quick pallet separation work automatically, thereby maximizing the work efficiency and reducing the manufacturing cost.

In order to achieve the above object,

The operating plate is rotated and reversed by the displacement difference obtained by elevating the feed roller of the operating plate, which is hinged to the upper plate of the platform by the lifting and lowering motion of the rack engaged with the pinion rotated by the motor, along the cam hole of the side plate. After the clamping and unclamping of the pallet, only the pallet located on the lower side of the loaded pallet can be placed on the conveyor continuously to achieve the purpose of this paper.

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

A pinion 106 coupled to the rotating shaft 105 which is rotated forward and backward by the driving force of the motor 102 seated on the support plate 101,

A rack 111 engaged with the pinion 106 and being lifted up and down by forward and reverse rotation of the pinion 106,

Lifting rack 112 is fixed to the rack 111 so that the accurate lifting operation of the rack 111 is coupled to the support 121 with a plurality of bearings (129),

An operating plate 116 coupled to the top plate 113 of the platform 112 by a hinge 114 for easy rotation and having a locking piece 117 for clamping the pallet 131;

A transfer roller 119 coupled to the fixing piece 118 of the operating plate 116 for rotation,

The feed roller 119 is configured to include a cam hole 124 formed in the side plate 123 of the support 121 to rotate or reverse the operating plate 116 while lifting up along the set cam diagram.

The cam hole 124 is formed by connecting the upper hole 125 and the lower hole 125 formed with the displacement difference to each other by the upper inclined surface 126 and the lower inclined surface 127.

In addition, when the transfer roller 119 is moved upward, the magnet 122 coupled to the lifting platform 112 to move while being in close contact with the upper inclined surface 126 of the cam hole 124 by a magnetic force,

When the transfer roller 119 is moved to the lower side is coupled to the hinge 114 connecting the upper plate 113 and the operating plate 116 to be moved while being in close contact with the lower inclined surface 127 of the cam hole 124 by elasticity. And further provided with an elastic member 115 to give elasticity to the operating plate 116.

The operation of this paper is as follows.

First, as shown in FIG. 2 of the present invention, the following operations will be described in a state in which pallets 131 on which a plurality of pallets are stacked are seated on the conveyor 132.

That is, in the state where the pallets 131 are seated on the conveyor 132 as described above, the lower hole in which the transfer roller 119 coupled to the fixing piece 118 of the operation plate 116 forms the cam hole 124 is provided. (128) The state is located in the upper portion.

In addition, the operating plate 116 to which the transfer roller 119 is coupled is rotated about the hinge 114 to be in a state of unclamping the pallet 131.

In the above state, as the motor 102 of the support plate 101 is driven by the instruction of the control box, the driving gear 103 and the interlocking gear 104 engaged with the driving gear 103 are rotated.

Then, the rotation shaft 105 coupled to the interlocking gear 104 also rotates to rotate the pinion 106 on both sides coupled to both sides of the rotation shaft 105.

Hereinafter, only the action derived by the pinion 106 of one side will be described because the action derived by the pinion 106 of both sides is the same.

The rotation force of the pinion 106 is converted into a linear motion by the rack 111 is engaged, the rack 111 and the platform 112 is moved upwards.

At this time, since the platform 112 is connected to the support 121 and the linear bearing 129, a smooth and accurate linear motion.

In addition, the upper side 113 attached to the upper side of the platform 112 and the operating plate 116 connected to the upper plate 113 and the hinge 114 along the upper side of the platform 112 also move upward.

In addition, the transfer roller 119 coupled to the fixing piece 118 of the operating plate 116 is also moved upward in the cam hole 124, the transfer roller 119 is the lower hole 128 and When the upper and lower inclined surface 126, 127 reaches the contact portion of the magnetic force of the magnet 122 is coupled to the platform 112.

That is, since the transfer roller 119, the fixed piece 118, and the operation plate 116 are all made of metal, the transfer roller 119 is in close contact with the upper inclined surface 126 of the cam hole 124 as shown in FIG. Will move up.

Then, when the feed roller 119 passes through the upper inclined surface 126 from the lower hole 128 of the cam hole 124 and enters the upper hole 125, a displacement difference occurs according to the cam diagram.

That is, when the transfer roller 119 is located in the lower hole 128, the pallet 131 is unclamped, but when the transfer roller 119 is located in the upper hole 125 as shown in FIG. As the 116 rotates about the hinge 114, the locking piece 117 of the operation plate 116 clamps the bottom surface of the flange of the second pallet 131.

At this time, the operating plate 116 is located in the upper hole 125 is the operating plate 116 because it falls in the elastic influence zone of the elastic member 115 is coupled to the hinge 114, instead of leaving the magnetic influence zone of the magnet 122. ) Is a state in which elasticity acts in the direction of the arrow shown in FIG.

Thus, the operation plate 116 and the engaging piece 117 can be firmly clamped on both sides of the second pallet (131).

As described above, when the second pallet 131 is clamped by the engaging piece 117 of the operation plate 116, the lifting platform 112 and the operation plate 116 are moved upward by the rotation of the motor 102. The high conveying roller 119 is also stopped by the direction of the control box after moving the upper set distance in the upper hole 125 to the upper side.

In addition, the second pallet 131 clamped to the locking piece 117 and the pallets 131 loaded thereon also move upward by a predetermined distance as shown in FIG. 5 by the upward movement of the operation plate 116. A stop is made.

As described above, when the second pallet 131 is separated from the first pallet 131, the first pallet 131 is supplied to the next process by the rotation of the conveyor 132.

In addition, after the first pallet 131 is removed and supplied to the next process, the motor 102 rotates in reverse by the instruction of the control box.

That is, the drive gear 103, the interlocking gear 104, the pinion 106 are reversely rotated by the reverse rotation of the motor 102, the rack 111, the platform 112, the top plate 113, the operating plate 116 and the feed roller 119 are in a state of lowering all to the original position.

Of course, the pallets 131 clamped to the engaging pieces 117 of the operating plate 116 are also lowered.

Then, the transport roller 119 is lowered as described above is lowered in close contact with the lower inclined surface 127 formed in the cam hole 124 when transported from the upper hole 125 to the lower hole 128.

That is, when the transfer roller 119 is positioned as the lower inclined surface 127 of the cam hole 124 as shown in FIG. 6, the elasticity of the elastic member 115 and the magnetic force of the magnet 122 are simultaneously applied.

However, since the elasticity of the elastic member 115 and the magnetic force of the magnet 122 are operated with almost the same force, the intermediate point between the center line of the upper hole 125 and the center line of the lower hole 128 is transferred to the blade point. When the center point of the 119 is located in the direction of the magnet 122, the center point is in close contact with the upper inclined surface 126 as it moves upward.

In addition, when the center point of the transfer roller 119 is positioned in the direction of the elastic member 115, the intermediate point between the center line of the upper hole 125 and the center line of the lower hole 128 is located in the direction of the elastic member 115, as opposed to the upward movement of the transfer roller ( 119 is lowered to the lower hole 128 while in close contact with the lower inclined surface (126).

When the feed roller 119 passes through the lower slope surface 127 from the upper hole 125 of the cam hole 124 and enters the lower hole 128, a displacement difference occurs according to the cam diagram.

That is, when the transfer roller 119 is located in the upper hole 125, the pallet 131 is clamped, but when the transfer roller 119 is located in the lower hole 128 as shown in FIG. As the 116 rotates backward about the hinge 114, the flange bottom surface of the second pallet 131 is placed on the conveyor 132 while the locking piece 117 of the operation plate 116 is unclamped.

Therefore, when the second pallet 131 is placed on the conveyor as described above, the pallets 131 are separated and placed on the conveyor 132 one by one while repeating the same means as described above.

On the other hand, the pallet 131, the height of the bar varies depending on its use. The low or high pallet 131 can cope with the height change of the pallet 131 by adjusting the height of the side plate 123 on which the cam hole 124 is formed.

In this way, this work is operated by the displacement difference obtained by lifting and lowering along the cam hole of the side plate the feed roller of the operating plate which is hinged to the upper plate of the platform by the lifting motion of the rack engaged with the pinion rotated by the motor. By rotating and counter-rotating the plate, the pallet is clamped and unclamped, and only the pallet located below is removed from the loaded pallet so that it can be placed on the conveyor continuously. Separation is possible and rapid pallet separation can be performed automatically to maximize work efficiency and reduce manufacturing cost.
