A pair of parallel conveying lines 2 are symmetrically arranged on both sides of the linear module 1. The linear module 1 is provided with a column 3 and a pushing arm 4 is obliquely supported. The tail end of the conveying line 2 is provided with a lower edge material support 5. The lower edge material support 5 A downward pressing cylinder 6 is mounted on the top, and a horizontal upper edge material blocking block 7 is connected to the bottom of the downward pressing cylinder 6. An upper edge material pressing groove 8 vertically aligned with the lower edge material support 5 is provided at the lower edge of the upper edge material blocking block 7. A flipping cylinder 9 is mounted below the lower edge material support 5, and a release baffle 10 is connected to the flipping cylinder 9. The release baffle 10 blocks the lower edge material support 5 with the vertical direction as the starting position within the stroke of the flipping cylinder 9 and connects with the lower edge material support 5 with the horizontal direction as the end position.

[0021] The linear module 1 and the conveyor line 2 are mounted on a lifting platform 11 , a gantry is mounted on the lifting platform 11 at the tail end of the conveyor line 2 , and the downward pressure cylinder 6 is hoisted on the gantry.

[0022] Furthermore, a pair of linear slides 12 perpendicular to the line diameter direction of the linear module 1 are horizontally arranged between the lifting platform 11 and the conveyor line 2, and an adjusting screw 13 with one end mounted on the lifting platform 11 and the other end connected to the conveyor line 2 is arranged in parallel in the middle of the linear slide 12, and the adjusting screw 13 has a handwheel.

[0023] Furthermore, a pair of side baffles 14 are provided on the outer side of the conveyor line 2 , and an L-shaped side edge material blocking spring piece 15 is provided at the tail of the side baffle 14 .

[0024] Furthermore, a proximity switch 16 is connected to the tail end of each conveying line 2, and the proximity switch 16 is aligned and arranged on the plane where the lower edge material support 5 and the upper edge material pressing groove 8 are located.

[0025] Furthermore, the propulsion arm 4 and the column 3 form a triangular stable structure, and the propulsion arm 4 spans the conveyor line 2 .

[0026] Furthermore, the lower edge material support 5 is hung just below the tail end of the conveyor line 2 through an integrally formed inverted L-shaped transfer arm.

[0027] Furthermore, the bottom of the linear module 1 is located at the tail end of the conveyor line 2 and is connected to a bracket, and the flip cylinder 9 is supported by the bracket.

[0028] Furthermore, the width of the release baffle 10 is adapted to the spacing of the conveyor line 2 .

[0029] The working principle of this device is:

[0030] During the equipment installation phase, the device needs to be connected to the unpacking assembly line. Different assembly lines have different design heights. The device uses a lifting platform 11 as a base to be compatible with assembly lines of various specifications.

[0031] After the assembly line is integrated, the size of the carton sheet 100 needs to be compatible, and the spacing of the conveyor line 2 is adjusted by turning the hand wheel so that the lateral width of the carton sheet 100 is just limited between the lateral baffles;

[0032] Figure 1 Only one carton sheet 100 is shown unpacked. In actual production, 50 or 100 carton sheets 100 can be placed vertically on the conveyor line 2 in order. The device first guides the carton sheet 100 before feeding one by one. The carton sheet 100 is carried on the conveyor line 2. The linear module 1 pushes the carton sheet 100 forward to compress the gap through the push arm 4. During the process, the proximity switch 16 monitors the correct position of the carton sheet 100 in real time, that is, the proximity switch 16 is used to detect whether the carton sheet 100 is skewed. As long as one of the proximity switches 16 cannot detect the carton sheet 100, it means that the carton sheet 100 is skewed. At this time, the conveyor line 2 on the side where the carton sheet 100 is not detected continues to transport until both proximity switches 16 can detect the carton.

[0033] The corrected carton sheet 100 is compressed and pressed by the push arm 4, and the upper edge of the carton sheet 100 abuts against the Figure 2 The upper edge of the pressing groove 8 is shown; the lower edge of the carton sheet 100 is pressed against the plate surface of the release baffle 10 by the pushing arm 4; the two sides of the carton sheet 100 are hooked by the side edge blocking spring 15; thus forming a closed one-way stack, such as Figure 1 The illustrated embodiment shows the carton sheet 100 being at the top of the stack.

[0034] Next, the carton sheet 100 is discharged in a single piece. At this time, the downward pressure cylinder 6 drives the upper edge blocking block 7 to vertically press the carton sheet 100 stuck in the upper edge pressing groove 8 downward. The carton sheet 100 itself has a certain structural strength and is pushed down by the downward pressure cylinder 6 to fall onto the lower edge material support 5. The next carton sheet 100 is then pushed by the linear module 1 to press against the side of the upper edge blocking block 7 (above the upper edge pressing groove 8); at this time, the carton sheet 100 is supported by the pushing arm 4, hooked by the side edge blocking spring 15, and dragged by the lower edge material support 5 , forming a stable state; then, when the release baffle 10 on the carton sheet 100 is turned 90 degrees and withdrawn under the control of the turning cylinder 9, it is connected to the lower edge material support 5; finally, the pressing cylinder 6 is withdrawn, the upper edge of the carton sheet 100 is out of the control of the equipment, and the entire carton sheet 100 is taken away by the negative pressure suction cup of the downstream assembly line. During the taking process, the side edge blocking spring piece 15 is deformed by force to make the carton sheet 100 pop out; when the pressing cylinder 6 is reset, a new carton sheet 100 at the top of the stack is formed, and the upper edge of the carton sheet 100 is stuck to the lower edge again. Figure 2 The upper edge of the material pressing groove 8 is shown. So far, the single sheet discharging process is completed.

[0035] In summary, the present invention provides a feeding machine for progressively feeding packaging carton sheets 100 piece by piece, which is compatible with various downstream assembly lines through the lifting platform 11, is compatible with carton sheets 100 of various sizes through the adjustment screw 13, and independently controls the conveyor line 2 through the proximity switch 16 to achieve the skew guidance of the carton sheet 100. With the cooperation of the side edge blocking spring piece 15 and the lower edge material support 5, an upper edge pressing groove 8 is designed on the upper edge blocking block 7 to achieve the sheet separation of the carton sheet 100. The whole equipment has the advantages of high precision and fast sheet output.
