[0034] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0035] Attached Figures 1-3The automatic feeder for the magazine of the present utility model includes a frame 1, two double-row belt conveyor lines 2 horizontally arranged inside the frame 1 and spaced vertically, and multiple magazines 3 for storing carriers.

[0036] The conveying directions of the two double-row belt conveyor lines 2 are opposite. One double-row belt conveyor line 2 is used to store the magazines 3 filled with carriers, and the other double-row belt conveyor line 2 is used to store the empty magazines 3.

[0037] By setting two double-row belt conveyor lines 2, the present utility model can not only store multiple magazines 3 filled with sheet products at one time to supply materials to the feeding module, but also store multiple empty magazines 3 at one time. Thus, it can not only realize automatic loading and unloading of the magazine 3 in a magazine clip form, reduce the frequency of manual loading and unloading, save time and effort, reduce labor, but also have a high space utilization rate.

[0038] Among them, the lower double-row belt conveyor line 2 will always convey the magazines 3 filled with carriers to the discharging end for the external picking and placing mechanism to grab; the upper double-row belt conveyor line 2 will always keep the feeding end in an empty state for the external picking and placing mechanism to place materials. If all the magazines 3 filled with carriers on the double-row belt conveyor line 2 are taken out, or the empty magazines 3 are filled, an alarm will be given to remind the staff to replenish materials and take down the empty magazines 3.

[0039] Further, as Figures 1-3 shown, a spacing adjustment mechanism 4 for simultaneously adjusting the spacing between the two double-row belt conveyor lines 2 is provided on the frame 1; the spacing adjustment mechanism 4 includes two sets of guiding components arranged vertically on the frame 1 at upper and lower intervals, two sets of screw-nut components arranged vertically on the frame 1 at upper and lower intervals, and a belt drive component for simultaneously driving the two sets of screw-nut components.

[0040] Each set of the guiding components includes two guide rods 41 placed perpendicular to the double-row belt conveyor line 2.

[0041] Each set of the screw-nut components includes two sets of screw pairs 42 placed perpendicular to the double-row belt conveyor line 2.

[0042] The belt drive component includes driven wheels 43 respectively arranged at the same end of the four screw pairs 42, a synchronous belt 44 sleeved on the four driven wheels 43 at the same time, a motor arranged on the frame 1, a driving wheel 45 arranged at the driving end of the motor, and a driving belt 46 sleeved on one of the driven wheels 43 and the driving wheel 45.

[0043] Each double-row belt conveyor line 2 includes a fixed belt conveyor line 21 fixedly arranged on the frame 1, and a movable belt conveyor line 22 movably arranged on two guide rails and connected to the two sets of screw pairs 42.

[0044] When the distance between two double-row belt conveyor lines 2 needs to be changed: The motor drives the driving wheel 45 to drive one of the driven wheels 43 to rotate through the driving belt 46. Since the synchronous belt 44 is sleeved on the four driven wheels 43 at the same time, four sets of lead screw pairs 42 are driven to drive the two movable belt conveyor lines 22 to approach or move away from the fixed belt conveyor line 21 simultaneously, realizing synchronous adjustment of the distance between the two double-row belt conveyor lines 2, which has the advantages of quick operation, time and labor saving, and high efficiency.

[0045] Furthermore, as Figure 2 shown, the distance adjustment mechanism 4 further includes two tensioning wheels 47 provided on the frame 1 for tensioning the synchronous belt 44 and the driving belt 46 respectively, playing a tensioning role.

[0046] Furthermore, as Figure 2 shown, both ends of the frame 1 are open, which is not only convenient for manual loading and unloading, but also convenient for external picking and placing mechanisms to pick and place.

[0047] Furthermore, as Figure 2 shown, the cross-section of the frame 1 is U-shaped, including a base 11 and side plates 12 vertically arranged on both sides of the base 11;

[0048] Both of the two double-row belt conveyor lines 2 are located between the two side plates 12, and the upper double-row belt conveyor line 2 is arranged on the top of the side plates 12;

[0049] By making the top of the frame 1 open and arranging the upper double-row belt conveyor line 2 on the top of the side plates 12, the present utility model can maximize the vertical distance between the two double-row belt conveyor lines 2 and transport higher-sized material boxes 3.

[0050] Furthermore, as Figure 2 shown, both ends of the guide rod 41 are respectively arranged on the two side plates 12;

[0051] One end of the lead screw pair 42 is arranged on one of the side plates 12, and the other end passes through the side plate 12;

[0052] The driven wheels 43, the synchronous belt 44, the driving wheel 45, the driving belt 46 and the tensioning wheels 47 are all arranged outside the side plates 12.

[0053] By arranging the two double-row belt conveyor lines 2 between the two side plates 12 and arranging the distance adjustment mechanism 4 outside the side plates 12, the present utility model can not only avoid interference, but also facilitate assembly and maintenance.

[0054] Furthermore, as Figure 3 shown, two hollow parts 13 are arranged on both of the two side plates 12 between the two double-row belt conveyor lines 2; the two hollow parts 13 are arranged at intervals along the conveying direction of the double-row belt conveyor lines 2;

[0055] The utility model is provided with a hollow part 13, which facilitates the staff to observe the condition of the material box 3 on the double-row belt conveyor 2 below through the hollow part 13.

[0056] Further, as Figure 3 shown, induction components 5 are arranged at both the feeding end and the discharging end of the two double-row belt conveyors 2, which facilitates knowing the entry and exit conditions of the carriers.

[0057] Further, the front and rear positions of the induction component 5 at the feeding end and the discharging end of the double-row belt conveyor 2 are adjustable, which facilitates installation and debugging.

[0058] Further, as Figures 1-2 shown, the two double-row belt conveyors 2 are respectively driven by two groups of driving mechanisms 6; each group of driving mechanisms 6 can drive the fixed belt conveyor 21 and the movable belt conveyor 22 to rotate synchronously, including a rotating shaft 61 that passes through the belt pulleys of the fixed belt conveyor 21 and the movable belt conveyor 22 at the same time, and a belt drive 62 for driving the rotating shaft 61 to rotate; the cross section of the rotating shaft 61 is polygonal;

[0059] Since the cross section of the rotating shaft 61 is polygonal, it not only facilitates the belt drive 62 to drive the rotating shaft 61 to drive the fixed belt conveyor 21 and the movable belt conveyor 22 to rotate at the same time to convey the material box 3, but also does not affect the distance adjustment between the fixed belt conveyor 21 and the movable belt conveyor 22, and has the advantages of simple structure and convenient installation.

[0060] Further, as Figure 3 shown, a pushing component 7 for pushing the carrier in the material box 3 onto the production line is arranged at the end of the movable belt conveyor 22 below; the pushing component 7 includes a support rod 71 and a pushing cylinder 72 arranged at the end of the support rod 71 and facing the feeding end of the production line;

[0061] During installation: the material box automatic feeder is placed in an L shape with the production line, and the external picking and placing mechanism is located at the right angle between the material box 3 automatic feeder and the production line; at the same time, the fixed belt conveyor 21 is close to the feeding end of the production line, and the movable belt conveyor 22 is far from the feeding end of the production line;

[0062] During operation: when the external picking and placing mechanism grabs the material box 3 and places it between the pushing cylinder 72 and the feeding end of the production line, the pushing cylinder 72 can push the carrier in the material box 3 onto the production line to complete feeding;

[0063] The utility model is provided with the pushing component 7 at the end of the movable belt conveyor 22. When the width of the double-row belt conveyor 2 is adjusted, the position of the pushing cylinder 72 can be adjusted synchronously with the movable belt conveyor 22. Compared with the prior art, the working stroke of the pushing cylinder 72 can be reduced, making the structure more compact.

[0064] Furthermore, as Figure 3 shown, the height of the support rod 71 on the movable belt conveyor line 22 is adjustable; the front, rear, left, and right positions of the pushing cylinder 72 on the support rod 71 are adjustable, which can not only reduce the machining accuracy of the support rod 71 but also facilitate assembly.

[0065] The above are only specific application examples of the present utility model, which do not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the rights of the present utility model.
