Description

Technical Field

[0001] This utility model relates to the field of automatic packaging, and in particular to a packaging box feeding mechanism. Background Technology

[0002] During the process of packaging LCD glass into boxes, the LCD glass needs to be transported and inspected on the conveyor line. At the same time, the packaging box needs to be clamped and transported to the conveyor line, and then the LCD glass is placed in the packaging box at intervals to complete the packaging of the LCD glass.

[0003] When packaging boxes are picked up and transported to the conveyor line, the boxes are stacked. When picking up a box, the clamp picks up the box in sequence, and the descent height gradually increases. That is, the first gripping descent height is 0, the second gripping descent height is the thickness of one box, the third gripping descent height is the thickness of two boxes, and so on. This results in the descent time and the descent stroke gradually increasing during the material retrieval process, which in turn requires a descent unit with a longer stroke, increasing costs.

[0004] In summary, how to achieve material handling for packaging boxes and reduce the descent distance has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to achieve material handling of packaging boxes and reduce the descent stroke;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a packaging box feeding mechanism, comprising: a shelf on which multiple packaging boxes are stacked; a conveyor line disposed on one side of the shelf; a lifting module disposed at the bottom of the shelf, adapted to drive the multiple packaging boxes to rise and fall; and a clamping module; after the clamping module clamps the packaging box located at the top of the shelf and places it on the conveyor line, the lifting module raises the remaining packaging boxes by a distance equal to the thickness of the packaging box, ready for the clamping module to clamp them.

[0008] In this solution, a lifting module mechanism is set up so that after the previous packaging box is clamped and placed on the conveyor line, the lifting module drives multiple packaging boxes to rise to a thickness of one packaging box, which facilitates the clamping module to clamp the boxes. In this way, the clamping module does not need to descend during the process of clamping the packaging boxes, thus avoiding the descent time and the gradual increase of the descent stroke. This enables the picking of packaging boxes and reduces the descent stroke.

[0009] To illustrate the specific structure of the lifting module, this utility model uses a lifting module comprising: a lifting slide, which is vertically and fixedly connected to the shelf; and a support frame, which is connected to the output end of the lifting slide and located inside the shelf.

[0010] In this solution, multiple stacked packaging boxes are supported on the support frame, and the lifting slide moves the support frame up and down, so that the packaging boxes can move up and down and be easily gripped by the clamping mechanism.

[0011] To illustrate the specific structure of the clamping module, this utility model adopts a clamping module comprising: a horizontal slide rail disposed above the shelf and conveyor line; a horizontal slide table disposed parallel to the horizontal slide rail; and a clamping assembly slidably disposed on the horizontal slide table and connected to the output end of the horizontal slide table.

[0012] In this solution, the clamp assembly is slidably connected to the horizontal slide rail, and the horizontal slide table provides the sliding power for the clamp assembly, enabling the clamp assembly to move above the shelf and above the conveyor line.

[0013] To illustrate the specific structure of the clamping assembly, this utility model employs a clamping assembly comprising: a first sliding plate, the bottom of which is slidably connected to the horizontal slide rail; two second sliding plates, which are respectively slidably disposed on both sides of the first sliding plate; a first cylinder, which is fixed to the first sliding plate and whose output end is connected to the second sliding plate, and is adapted to drive the second sliding plate to move along the length direction of the first sliding plate; a second cylinder, which is fixed to the second sliding plate and passes through the first sliding plate; and a clamping plate disposed at the output end of the second cylinder.

[0014] The first cylinder drives the corresponding clamping plate to move in the length direction, and the second cylinder drives the clamping plate to move up and down. The length direction movement of the clamping plate is to clamp packaging boxes of different lengths, and the up and down movement of the clamping plate is to place the packaging boxes on the conveyor line.

[0015] In order to enable the stacking of packaging boxes of different lengths and to ensure stability during the upward movement of the packaging boxes, this utility model adopts a sliding mechanism to set baffles on both sides of the bottom of the shelf; the sliding mechanism keeps the two baffles abutting against the two sides of the packaging box at all times.

[0016] The two baffles abut against the sides of the packaging box, ensuring the stability of the packaging box during the rising process. In addition, the sliding design on both sides of the baffles can abut against the sides of packaging boxes of different lengths.

[0017] To illustrate the specific structure of the sliding mechanism, this utility model uses a sliding mechanism comprising: a slide rail disposed at the bottom of the shelf; a slider disposed at the bottom of the baffle and slidably connected to the slide rail; a nut disposed at the bottom of the baffle; and a lead screw driven by a motor, rotatably disposed at the bottom of the shelf and threadedly connected to the nut; when the motor is started, it drives the two baffles to move closer or further apart.

[0018] The baffle and the bottom of the shelf are connected by a slider and a slide rail. The motor rotates, which drives the lead screw to rotate. The rotation of the lead screw drives the lead screw nut to move on the lead screw, which in turn drives the baffle to slide relative to the shelf. In this way, the distance between the two baffles can be adjusted to accommodate packaging boxes of different widths.

[0019] The beneficial effects of this utility model are as follows: This utility model is a packaging box feeding mechanism. By setting up a lifting module mechanism, after the previous packaging box is clamped and placed on the conveyor line, the lifting module drives multiple packaging boxes to rise to a thickness of one packaging box, which facilitates the clamping module to clamp the boxes. In this way, the clamping module does not need to descend during the process of clamping the packaging boxes, thus avoiding the descent time and the gradual increase of the descent stroke. This enables the picking of packaging boxes and reduces the descent stroke. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] like Figure 1-2As shown, this utility model is a packaging box feeding mechanism, including: a shelf 1 on which multiple packaging boxes 2 are stacked; a conveyor line 3 disposed on one side of the shelf 1; a lifting module 4 disposed at the bottom of the shelf 1, adapted to drive the multiple packaging boxes 2 to rise and fall; and a clamping module 5. After the clamping module 5 clamps the packaging box 2 located at the top of the shelf 1 and places it on the conveyor line 3, the lifting module 4 raises the remaining packaging box 2 by a distance equal to the thickness of the packaging box 2, so that the clamping module 5 can clamp it.

[0027] In this solution, a lifting module mechanism is set up so that after the previous packaging box is clamped and placed on the conveyor line, the lifting module drives multiple packaging boxes to rise to a thickness of one packaging box, which facilitates the clamping module to clamp the boxes. In this way, the clamping module does not need to descend during the process of clamping the packaging boxes, thus avoiding the descent time and the gradual increase of the descent stroke. This enables the picking of packaging boxes and reduces the descent stroke.

[0028] like Figure 2 As shown, in order to illustrate the specific structure of the lifting module, the present invention adopts a lifting module 4 including: a lifting slide 41, which is vertically fixedly connected to the shelf 1; and a support frame 42, which is connected to the output end of the lifting slide 41 and located inside the shelf 1.

[0029] In this solution, multiple stacked packaging boxes are supported on the support frame, and the lifting slide moves the support frame up and down, so that the packaging boxes can move up and down and be easily gripped by the clamping mechanism.

[0030] like Figure 3 As shown, in order to illustrate the specific structure of the clamping module, the present invention adopts a clamping module 5 including: a horizontal slide rail 51, which is disposed above the shelf 1 and the conveyor line 3; a horizontal slide table 52, which is disposed parallel to the horizontal slide rail 51; and a clamping assembly, which is slidably disposed at the horizontal slide table 52 and connected to the output end of the horizontal slide table 52.

[0031] In this solution, the clamp assembly is slidably connected to the horizontal slide rail, and the horizontal slide table provides the sliding power for the clamp assembly, enabling the clamp assembly to move above the shelf and above the conveyor line.

[0032] like Figure 3As shown, to illustrate the specific structure of the clamping assembly, this utility model uses a clamping assembly comprising: a first sliding plate 53, the bottom of which is slidably connected to the horizontal slide rail 51; two second sliding plates 54, which are respectively slidably disposed on both sides of the first sliding plate 53; a first cylinder 55, which is fixed to the first sliding plate 53, and whose output end is connected to the second sliding plate 54, and is adapted to drive the second sliding plate 54 to move along the length direction of the first sliding plate 53; a second cylinder 56, which is fixed to the second sliding plate 54 and passes through the first sliding plate 53; and a clamping plate 57, which is disposed at the output end of the second cylinder 56.

[0033] The first cylinder drives the corresponding clamping plate to move in the length direction, and the second cylinder drives the clamping plate to move up and down. The length direction movement of the clamping plate is to clamp packaging boxes of different lengths, and the up and down movement of the clamping plate is to place the packaging boxes on the conveyor line.

[0034] like Figure 2 As shown, in order to enable the stacking of packaging boxes of different lengths and to ensure stability during the upward movement of the packaging boxes, this utility model adopts a sliding mechanism to provide baffles 6 on both sides of the bottom of the shelf 1; the sliding mechanism keeps the two baffles 6 abutting against the two sides of the packaging box 2 at all times.

[0035] The two baffles abut against the sides of the packaging box, ensuring the stability of the packaging box during the rising process. In addition, the sliding design on both sides of the baffles can abut against the sides of packaging boxes of different lengths.

[0036] like Figure 2 As shown, to illustrate the specific structure of the sliding mechanism, this utility model uses a sliding mechanism comprising: a slide rail 61, which is disposed at the bottom of the shelf 1; a slider 62, which is disposed at the bottom of the baffle 6 and slidably connected to the slide rail 61; a nut, which is disposed at the bottom of the baffle 6; and a lead screw 63, which is driven by a motor 64, rotatably disposed at the bottom of the shelf 1, and threadedly connected to the nut; when the motor 64 is started, it drives the two baffles 6 to move closer or further apart;

[0037] The baffle and the bottom of the shelf are connected by a slider and a slide rail. The motor rotates, which drives the lead screw to rotate. The rotation of the lead screw drives the lead screw nut to move on the lead screw, which in turn drives the baffle to slide relative to the shelf. In this way, the distance between the two baffles can be adjusted to accommodate packaging boxes of different widths.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
