Auto Sheet Insertion Unit {Auto Loading Unit of a Pad}

The present invention relates to an automatic slip sheet insertion device using a parallel articulated link, and more particularly, when the product packaging is completed in the production process, the unit packaging is easily broken or stuck to each other due to the characteristics of the product is difficult to separate products It is a slip sheet inserting device that quickly and repeatedly supplies the sheet of paper in every stacking layer so as to prevent the fall of the stacking layer or the handling of cargo. The present invention relates to a dedicated interleaver automatic insertion device with a simple and inexpensive parallel articulated link structure that can maximize the operation rate.

Generally, a factory produces a product and loads a finished product on a pallet in various patterns for shipment or storage.

Conventionally, as a method of loading the product on a pallet, a number of workers manually load the product on a pallet, and recently, a product is automatically loaded on a pallet as a palletizing automation device such as a robot.

As the method of loading the product on the pallet is automated as described above, a lot of products are loaded on the pallet in a short time with a certain quality. As a result, the palletizing robot replaced with an additional hand or a separate hand and then inserted a sheet of paper or installed a separate sheet automatic inserting device.

At this time, when palletizing robot and pallet inserting work are performed in parallel with the palletizing robot, a separate hand for inserting the slip sheet is combined with the palletizing hand to increase the hand weight, thereby limiting the palletizing pattern implementation. In other words, there is a need for an expensive robot with a high payload, or a separate hand for adsorption of ice sheets and automatic replacement to increase productivity and lower productivity by temporarily reducing production speed. there was.

In particular, in the case of reducing the shape of the slip sheet from a monolithic quadrilateral to a plurality of narrow strips in order to reduce costs, the above-mentioned temporary production speed reduction problem has been raised.

In the case of using a separate automatic sheet inserting device like the latter, the sheet can be inserted only on the upper surface of the pallet before transporting the pallet to the stacking position due to the interference of the loading work space with the robot. In such a case, or a device configured to allow interleaving at every loading floor, a pallet that requires a large space for installation so as not to interfere with the work of the robot, or which has a larger size and an operation cycle time becomes faster. There is a problem that the investment cost is increased and productivity is lowered because it is relatively slow compared to the aging robot.

In particular, in the case of a product having a high unit density (that is, a weight to volume ratio) of the product, the above problem is more serious.

The present invention has been made in order to solve the above problems, when loading the finished product packaging on the pallet after production in the production process is easily broken due to the characteristics of the product, it is difficult to separate the separation layer or load of the product By supplying the automatic slip sheet inserting device repeatedly and quickly for every loading layer to prevent the collapse during transportation and handling of Its purpose is to provide a dedicated interleaver automatic insertion device with a simple and inexpensive parallel articulated link structure that can maximize the work productivity of automatic loading devices such as robots, such as occupying a minimum installation space.

Mount the interlude loading cart 52 formed to stack the interlude 4 'at the same time, and fix the rod side end of the replacement cylinder 51 to the lower one side of the interlude loading cart 52, and the replacement An automatic switchable gantry preparation unit 50 fixedly coupled to the body of the cylinder 51 in parallel with the trolley rail 53 at the center of one end of the trolley rail 53;

The slipper adsorption unit 40 sucks the first slipper 4 or the second slipper 4 'from the slipper loading cart 52 of the slipper preparation unit 50, lifts it up and down by the lifting cylinder 31, and then parallels it. When the joint link completes the rotation of the interleaver insert position by the rotating cylinder 21 with respect to the main body 12 of the body part 10, the interleaver adsorbed by the mechanical characteristics of the parallel joint link (4 (4 ') remains unchanged, and the lifting cylinder 31 is lowered, so that the slippers 4 and 4' adsorbed on the upper surface of the product loading layer can be repeatedly and exactly placed in the same position. It is configured to be.

An example of the operation of the present invention is as follows.

When the palletizing system starts automatic operation, the replacement cylinder 51 of the ice sheet preparation unit 50 is operated to transfer the ice sheet stacking cart 52 to one end, and to put moisture on the upper surface of the pallet primarily. The integrated second interliner 4 'of the upper part of the upper part of the wick adsorption part 40 is accurately positioned, and then the lifting cylinder 31 of the lifting part 30 that supports the wick adsorption part 40 is connected to the wick adsorption part ( The second slipper 4 'in which the slipper adsorption position detection sensor of the sensor part 44 formed at the lower end of the slippery adsorption portion 40 is loaded on the slipper loading cart 43; When the upper end of the) is detected, the predetermined amount is lowered by the set time, the operation of the lifting cylinder 31 is stopped, and the second separator 4 'is vacuum sucked, and when the adsorption is completed, the lifting cylinder 31 is operated. Raise the adsorption part 40 as much as possible.

Subsequently, when the empty pallet 2 is transferred to the product loading position by the conveyor 1 and the setting is completed at the loading work position, the second slip sheet 4 'to be inserted at the bottom end is sucked up and held at the highest height. The liver adsorption part 40 of the present invention operates the cylinder 21 for rotation of the rotating part 20 so that the long axis link 22 on one side of the parallel articulated link is referred to the support part 24 of the main frame 12. By rotating a certain angle to the ball pallet (2) is moved to the upper position,

At this time, due to the theoretically well-known kinematic operation characteristics of the parallelogram link, the single axis link 23 is rotated to the upper position of the ball pallet 2 while maintaining the posture parallel to the main frame 12. At the time of adsorption of the interleave sheets 4 and 4 ', the posture of the sliding section 30 attached to one end of the link 23 or the interstitial adsorption section 40 formed at one end of the sliding section 30 does not change. It remains the same as the posture.

After the rotation of the rotating part 20 is completed, the lifting device 31 for lifting and lowering the lifting device 30, which supports the slipping device 40, adsorbs and holds the second insulating paper 4 '. Ascending and lowering the 40 at a constant speed, the lifting cylinder 31 when the sensor detachable position detection sensor of the sensor unit 44 formed on the lower end of the slipper adsorption unit 40 detects the upper end of the empty pallet (2) To stop the operation and desorption by vacuum breaking the second interleaver (4 '), and when the desorption is complete, operate the lifting cylinder (31) to raise the interleaver adsorption unit (40) as much as possible and then the new interleaver (4) (4'). Return to the home position waiting to adsorb).

Subsequently, the robot 3 picks up the product and forms the first loading layer according to the loading pattern on the second sheet 4 'of the pallet by loading the product, and in parallel with the progress of the loading operation of the robot 3.
