[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Attachment Figure 1-2 The automatic sheet product loading machine of the present invention is used to place the carriers in the material box 13 one by one on the production line, and includes a feeding module 1 and a loading module 2;

[0025] The loading module 2 includes an XZ-axis linear module 21 provided at one end of the feeding module 1, a gripper assembly 22 provided at the driving end of the XZ-axis linear module 21 for taking and placing the material box 13 from the feeding module 1, and a pushing cylinder 23 facing the feeding end of the production line for pushing the carrier in the material box 13 onto the production line;

[0026] During operation: the XZ-axis linear module 21 drives the gripper assembly 22 to grab the material box 13 filled with carriers from the feeding module 1, and aligns the outlet of the material box 13 filled with carriers with the feed end of the production line, so that one of the carriers is at the same height as the production line; then the pushing cylinder 23 is used to push the carrier in the material box 13 that is at the same height as the production line onto the production line to complete the loading; then the XZ-axis linear module 21 drives the gripper assembly 22 to adjust the height of the material box 13 so that another carrier is at the same height as the production line; then the pushing cylinder 23 is used to continue to push the carrier in the material box 13 that is at the same height as the production line onto the production line; the cycle continues until all the carriers in the material box 13 are pushed onto the production line.

[0027] Further, if Figure 2 As shown, the clamping jaw assembly 22 includes a mounting base 221 vertically arranged at the driving end of the XZ-axis linear module 21, a lower clamping plate 222 horizontally arranged at the bottom of the mounting base 221, a height adjustment module 223 vertically arranged on the mounting base 221 and located above the lower clamping plate 222, a clamping cylinder 224 vertically arranged at the driving end of the height adjustment module 223 with the driving end facing downward, and an upper clamping plate 225 horizontally arranged at the driving end of the clamping cylinder 224;

[0028] When it is necessary to grab the material box 13, the XZ-axis linear module 21 drives the clamping claw assembly 22 to move toward the material box 13 until the material box 13 is located between the upper clamping plate 225 and the lower clamping plate 222, and at the same time, the bottom of the material box 13 contacts the lower clamping plate 222, and then the upper clamping plate 225 is driven downward by the clamping cylinder 224 to clamp the material box 13 together with the lower clamping plate 222 to complete the material removal; if a material box 13 of a different height is replaced, the distance between the clamping cylinder 224 and the lower clamping plate 222 is adjusted by the height adjustment module 223, so that the clamping force can be adjusted according to the material box 13 of different heights to avoid deformation of the material box 13 and material jamming due to excessive clamping force.

[0029] Further, if Figure 2 As shown, the clamping surfaces of the upper clamping plate 225 and the lower clamping plate 222 are both provided with positioning grooves 226; the positioning grooves 226 are used to accommodate the protrusions 131 at the top or bottom of the magazine 13;

[0030] The present invention provides a positioning groove 226 to accommodate the protrusion 131 at the top or bottom of the material box 13, which not only prevents the material box from being misaligned during the clamping process but also plays a role in positioning.

[0031] Further, if Figure 2 As shown, the height adjustment module 223 is a manual linear slide; a locking assembly 227 is provided on the slide of the manual linear slide;

[0033] Further, if Figure 1 As shown, the feeding module 1 includes a box body 11 with a U-shaped cross-section, two material box conveying lines 12 horizontally arranged in the box body 11 and spaced apart in an upper and lower direction, and a plurality of material boxes 13 for storing carriers; the two material box conveying lines 12 have opposite conveying directions, one of which is used to store material boxes 13 filled with carriers, and the other is used to store empty material boxes 13;

[0034] The utility model is provided with two material box conveying lines 12, which can not only store multiple material boxes 13 filled with sheet products at one time to feed the loading module 2, but also store multiple empty material boxes 13 at one time, thereby realizing automatic loading and unloading of the material boxes 13, reducing the frequency of loading and unloading by personnel, saving time and effort, reducing labor, and achieving high space utilization;

[0035] The lower material box conveyor line 12 will always convey the material boxes 13 filled with carriers to the discharge end, so that the XZ-axis linear module 21 can drive the clamping assembly 22 to grab them; and the upper material box conveyor line 12 will always keep the feeding end in an empty state, so that the XZ-axis linear module 21 can drive the clamping assembly 22 to discharge the materials; if all the material boxes 13 filled with carriers on the material box conveyor line 12 are taken out, or the empty material boxes 13 are full, an alarm will be triggered to remind the staff to replenish the materials and remove the empty material boxes 13.

[0036] Further, if Figure 1 As shown, the material box conveyor line 12 adopts a double-row belt conveyor line, which is convenient for the gripper assembly 22 to grab the material box 13, and the width of the double-row belt conveyor line is adjustable, which can adapt to carriers of different sizes and has strong compatibility.

[0037] Furthermore, sensors 14 for sensing the material boxes 13 are provided at both ends of the material box conveying line 12, so as to facilitate knowing the entry and exit status of the material boxes 13.

[0038] Further, if Figure 1 As shown, the side of the material box conveyor line 12 close to the production line is a fixed belt conveyor line 121, and the side away from the production line is a movable belt conveyor line 122; the pushing cylinder 23 is installed on the movable belt conveyor line 122 through the support rod 24;

[0039] When the width of the material box conveyor line 12 is adjusted, the position of the pushing cylinder 23 can be adjusted synchronously with the movable belt conveyor line 122, thereby reducing the stroke of the pushing cylinder 23 and making the structure more compact.

[0040] Further, if Figure 1 As shown, the height of the support rod 24 on the movable belt conveyor line 122 is adjustable; the front, back, left and right positions of the pushing cylinder 23 on the support rod 24 are adjustable, which not only reduces the processing accuracy of the support rod 24, but also facilitates assembly.
