[0002] After the gypsum boards or panels are stacked and packed, they need to be covered with protective paper shells. The stack is in the shape of a rectangular parallelepiped. The protective shell includes a top plate and corner guards. The corner guards are adhered to the top plate, and the outer sides of the corner guards are folded downwards - the corner guards are used to protect the outer edges of the upper part of the stack (along the length of the board).

[0003] The raw material for the corner protector is a piece of flat cardboard. The folding action can be done by manual pressing. During the processing of the corner protector, the important steps are to apply glue and relieve stress on the corner protector (if the stress is not relieved during the folding of the flat cardboard, the processed corner protector will not be effective).

[0004] The driving cylinder refers to an electric cylinder, a hydraulic cylinder or a pneumatic cylinder.

[0005] Package labeling refers to labeling between the protective shell and the stack (the surface of the packaged stack is coated) - used to connect the protective shell to the stack. Package labeling can also be labeled separately on the protective shell.

[0032] like Figures 1 to 4As shown, the corner protection stacking and positioning mechanism includes a processing frame 2 and a corner protection material stacking frame 3. Two corner protection material stacking frames 3 are provided, and the processing frame 2 is supported by a supporting structure. Each corner protection material stacking frame 3 is used to stack the raw materials for making corner protection - corner protection raw material paperboard. The corner protection material stacking frame 3 is lower than the processing frame 2, and one end of the corner protection material stacking frame 3 is located below the processing frame 2. Each corner protection material stacking frame 3 is matched with a processing platform 4, and the processing platform 4 is arranged below the processing frame 2. A picking device 51 is provided above each processing platform 4, and the picking device 51 is used to pick up the corner protection raw material paperboard located on the corner protection material stacking frame 3. A negative pressure suction cup can be used as a picking device, and then the corner protection raw material paperboard is picked up by the negative pressure adsorption principle. A cutting device 52 is provided above each processing platform 4, and a paperboard fixing device is provided at the tail end of each processing platform 4. The paperboard fixing device is used to fix the end of the corner protection raw material paperboard. A glue spraying device 41 is provided above the front side of each processing platform 4 , a picking device 51 can be moved in the left-right direction, the picking device 51 can be raised and lowered, a cutting device 52 can be raised and lowered, and the cutting device 52 can be moved in the left-right direction.

[0033] like Figures 2 to 4 As shown, the corner protection stacking and positioning mechanism is used to carry out the work of streamlining the gluing and stress relief of the raw materials during the corner protection processing. The working process of the corner protection stacking and positioning mechanism is: pick up the corner protection raw material cardboard located on the corner protection material pile rack 3 through the picking device 51, and each picking device 51 only picks up one corner protection raw material cardboard at a time → the picking device 51 moves to the right, and then drags the raw material cardboard to the processing platform 4. During the dragging process, the glue spraying device 41 sprays glue on the upper side of the raw material cardboard (the width of the spraying is related to the connection part with the top plate) → after dragging in place, the picking device releases the raw material cardboard → fixes the end of the cardboard through the cardboard fixing device → the cutting device 52 descends → the cutting device performs a certain cutting work on the cardboard from right to left, thereby eliminating stress → the processed corner protection raw material board is ready for the next production process. The beneficial effect of the corner protection stacking and positioning mechanism is that it is conducive to the streamlining, mechanization, and automation of the gluing and stress relief work of the corner protection raw material board, thereby facilitating the improvement of the work efficiency of production and processing.

[0034] like Figure 2 and Figure 3As shown, a slide 5 is slidably connected to the processing frame 2, so that the slide 5 can move left and right. For example, a guide rail is provided on the front side of the processing frame 2, a slider matched with the guide rail is provided on the slide 5, and a guide wheel group is provided on the rear side of the slide, and the guide wheel group clamps the rear side of the processing frame 2, and is then used for guiding work.

The picking device 51 is connected to the lifting frame 53, and the lifting frame 53 is slidably connected to the slide 5 in the up and down directions. A first driving cylinder 54 is connected between the lifting frame 53 and the slide 5, and the first driving cylinder 54 is used to drive the lifting frame to rise and fall.

[0035] like Figure 2 and Figure 3 As shown, the cutter device 52 is connected to the knife holder 55, and the knife holder 55 is connected to the lifting frame 53 by sliding in the up-down direction, and a second driving cylinder 56 is connected between the knife holder 55 and the lifting frame 53. In the switching process from the above-mentioned dragging operation from left to right to the cutting operation from right to left, after releasing the corner guard raw material board, it is only necessary to fine-tune the picking device 51 upwards and then lower the knife holder 55 to lower the cutter device to the cutting position - in the cutting process from right to left, the negative pressure suction cup releases the negative pressure, and its lower surface can slightly press the cardboard to a certain extent, which is conducive to ensuring the accuracy of the cutting path.

[0036] like Figure 2 and Figure 3 As shown, the sliding drive mechanism includes a driving shaft 42, two driving pulleys 43 and two driven pulleys 44, the two driving pulleys 43 are arranged on the driving shaft 42, and the driving shaft 42 is rotatably connected to the processing frame 2.

A fourth drive cylinder 49 is connected between the limit frame 48 and the structural member, and the fourth drive cylinder 49 is used to facilitate timely adjustment of the position of the limit frame.

[0039] like Figure 2 As shown, each head end of each corner protection material pile rack 3 is slidably connected with a tray, and the tray can slide in the left and right directions, which is conducive to adjusting the length of the corner protection material pile rack, and is suitable for processing corner protections of different lengths, and is conducive to improving the versatility of the corner protection stacking and positioning mechanism.

[0040] like Figure 2 As shown, a baffle rod 33 is provided on one side of each corner material pile rack 3. The baffle rod 33 is vertically arranged and extends above the corner material pile rack 3.

[0042] like Figure 1 and Figure 5 As shown, the working process of the packaging labeling system is as follows: two corner protection raw material paperboards are glued and stress-relieved through the corner protection stacking positioning mechanism 8, and the processed corner protection raw material paperboards are placed on the processing platform 4 for standby (one corner protection raw material paperboard on each processing platform) → the picking robot 73 places a top plate on the corner protection raw material plate on the processing platform 4, so as to achieve the bonding of two corner protection raw material paperboards on the top plate to form a semi-finished protective shell → the picking robot 73 picks up the top plate to place the semi-finished protective shell on the stack on the stacking conveying device 7 → fold the outer sides of the two corners to the side of the stack and label 13.
