Description

Technical Field

[0001] The present invention relates to the technical field of stacking, and in particular to a forward and reverse stacking mechanism and method for materials. Background Art

[0002] Objects such as medicine plates and milk tablets need to be stacked upside down. The existing devices for stacking them upside down are slow, which reduces the speed of the subsequent cartoning machine.

[0003] For example, on September 14, 2018, a patent with the publication number CN108529181A, entitled "A Method for Stacking Workpieces in Positive and Negative Directions and a Stacking Device Therefor," was published. The patent includes a first conveyor belt, a flipping mechanism, and a second conveyor belt. The first conveyor belt is connected to the previous production line, and the second conveyor belt is connected to the next production line. The flipping mechanism is arranged between the first conveyor belt and the second conveyor belt, connecting the two conveyor belts. The invention is used for a production line in which a positive and negative stacking process is performed on two workpieces in a manufacturing plant. The invention can automatically stack the two workpieces on the production line in a positive and negative manner and send them to the next process, thereby effectively reducing production costs. However, in the above literature, the flipping mechanism used requires operating time, and the flipping mechanism only needs to be turned on. It can adsorb a material, resulting in the next piece of material cannot be sent out before the flipping mechanism completes the entire flipping action. The transportation equipment or card issuing machine must wait for the currently flipped material to be flipped before sending out the next piece of material, resulting in limited production efficiency. There must be a period of interruption between each material sending for the flipping mechanism to work. Since the flipping mechanism is a reciprocating operation, it needs to move from the initial position to the top of the material to grab it, and then move in the opposite direction to transport the material to the destination. Both movements need to be re-accelerated from a stationary state. The flipping mechanism cannot reach the maximum speed immediately when it starts, and the flipping speed cannot be too fast due to the impact resistance of the material during flipping. Therefore, the traditional flipping mechanism will take a lot of time to go back and forth, which reduces the production speed. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a forward and reverse stacking mechanism and method for materials to solve the problem of slow production speed.

[0032] The transport member 6 includes a horizontal moving member 9 connected to the support frame 7 for horizontal movement. The horizontal moving member 9 is connected to a first clamping assembly 10 through an up and down moving member 8 for up and down movement.

[0043] A counting sensor connected to the controller is provided in each of the grids to detect the amount of material in each grid to prevent shortage or excess of material in subsequent packaging boxes.

[0044] Based on the above embodiment, a method for stacking materials in both directions includes:

[0045] Step 1: The forward material-discharging part and the reverse material-discharging part discharge materials synchronously. The forward material-discharging part transports a plurality of materials with the front side facing upwards, which is the same number as the clamping parts, to a grid on the feeding crawler 4. The reverse material-discharging part transports a plurality of materials with the reverse side facing upwards, which is the same number as the clamping parts, to a grid on the feeding crawler 4.

Alternatively, when the materials do not need to be stacked, the controller controls the material collecting crawler 5 to transport the materials thereon to the boxing part 2.

[0049] When the number of clamps is four, such as Figure 6 As shown, Figure 6 This is a diagram illustrating four pieces of material within a single grid of the present invention. The number of clamps is four or more, the feed track 4 and the receiving track 5 are aligned in four or more grids, and the clamps are located four grids to the right of the first grid of the feed track 4. The numbers within the grid represent the material: 1 represents a single piece of material facing up, referred to as a "positive board," 1111 represents four pieces of material facing up, 2 represents a single piece of material facing down, referred to as a "reverse board," 2222 represents four pieces of material facing down, and 0 represents no material within the grid.

[0051] The naming of the feeding track 4 at this time is as follows: in the feeding track 4, the grid to the left of the grid just below the suction cup 14 is named the first grid of the feeding track 4. From the first grid to the left, there are the second grid, the third grid, the fourth grid, the fifth grid, etc.

[0055] The controller controls the feeding crawler 4 to move one grid to the right. At the same time, the controller controls the transporting member 6 to move a material on the feeding crawler 4 to the receiving crawler 5.

[0056] The controller controls the feeding track 4 to move one grid to the right again, and at the same time, the controller controls the transport part 6 to move a material on the feeding track 4 to the receiving track 5. At this time, the first grid of the feeding track 4 faces the negative grid of the receiving track 5, and the second grid of the feeding track 4 faces the first grid of the receiving track 5. At this time, the first grid and the second grid of the feeding track 4 are under the suction cup 14.

At this time, the materials in the first grid of the receiving track 5 are: positive board, reverse board, positive board, reverse board. At this time, the materials in the second grid of the receiving track 5 are: reverse board, positive board.
