Description

Technical Field

[0001] The invention relates to a cup stacking machine, in particular to an automatic cup stacking machine, and belongs to the technical field of cup stacking machine machinery. Background Art

[0002] The cup stacking machine is a mechanical device used to stack cups, etc. It is often used in the stacking process of disposable cups and disposable bowls. After the cup making machine makes the disposable cups, the disposable cups are taken from the cup making machine to the cup stacking machine for stacking by manual or mechanical cup suction.

[0003] For example, in the fully automatic cup stacking machine disclosed in application number CN201821480781.9, after the disposable cups are taken and placed on the cup stacking mechanism, the stacking mechanism transports the stacked disposable cups to the cup moving mechanism, and then the cup stacking mechanism returns to its original position, and stops taking and placing cups in the cup stacking machine during the transportation. Such intermittent cup transfer has low production efficiency and it is difficult to improve market economic benefits. In addition, in order to adapt to production, the stacked cups need to be adjusted from a vertical state to a horizontal state. The adjustment is achieved by using a rotating pick-and-place manipulator structure, that is, the manipulator is used to swing and rotate at 90°.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 2As shown, an automatic cup stacking machine includes a frame 1, a cup picking and placing mechanism 2, a double-drive cup stacking mechanism 3, a transfer cup collecting mechanism 4, an output cup pushing mechanism 5 and a conveying mechanism 6, wherein the cup picking and placing mechanism 2, the double-drive cup stacking mechanism 3, the transfer cup collecting mechanism 4 and the output cup pushing mechanism 5 are respectively fixedly connected to the frame 1; the cup picking and placing mechanism 2 is located above the double-drive cup stacking mechanism 3 in the longitudinal direction, the double-drive cup stacking mechanism 3 is located at the front end of the frame 1, the transfer cup collecting mechanism 4 is located between the double-drive cup stacking mechanism 3 and the output cup pushing mechanism 5, and the output cup pushing mechanism 5 is arranged toward the conveying mechanism 6, and the conveying mechanism 6 is located laterally behind the transfer cup collecting mechanism 4 and at the end of the frame 1; the double-drive cup stacking mechanism 3 reciprocates in the longitudinal and transverse directions relative to the transfer cup collecting mechanism 4, and the transfer cup collecting mechanism 4 reciprocates in the longitudinal and transverse directions relative to the output cup pushing mechanism 5 and performs self-turning motion. The cup picking and placing mechanism 2 of the present invention includes a manipulator suction cup and a picking and placing driving device that drives the manipulator suction cup to perform longitudinal and transverse motions. The mechanical arm suction cup of the cup picking and placing mechanism 2 will be taken out from the cup making machine at one time and placed in the double-drive cup stacking mechanism 3 for cup stacking. In the actual production process, when the left cup stacking drive unit 3100 transports the stacked disposable cups to the next process, the right cup stacking drive unit 3100 can continue the cup stacking process. The double-drive cup stacking method can ensure that the production does not stop, thereby improving production efficiency. After the cups are stacked, the cups are sent through the transfer and collection cup mechanism 4, and then the cup pushing mechanism 5 pushes the cups in the transfer and collection cup mechanism 4 to the conveying mechanism 6.

[0037] like Figure 3 As shown, the double-drive cup stacking mechanism 3 includes two cup stacking drive units 3100 with the same structure and staggered arrangement, and the cup stacking drive unit 3100 includes a limit column 3110 and a cup stacking drive structure that drives the limit column 3110 to move in the longitudinal and transverse directions, and there is a gap between two adjacent limit columns 3110. The cup stacking drive unit 3100 of the present invention has the same structure as the cup stacking drive unit 3100 on the right side, and can move in the longitudinal and transverse directions, so that the machine can be prevented from colliding during the production process; at the same time, the two cup stacking drive units 3100 are arranged relatively, with a compact structure, which is conducive to reducing the mechanical installation space. The mechanism can place the disposable cups made by the cup making machine at the gap between the adjacent limit columns 3110 for stacking through the cup picking and placing mechanism 2. At the same time, the gap between the limit columns 3110 can be adjusted according to the size of the cup, and other products, such as disposable bowls, disposable plates, etc., can also be stacked, with better adaptability. In addition, the cup placing connector 3140 is provided with a cup pushing groove 3141, which can cooperate with the transfer and collection cup mechanism 4 to push the stacked disposable cups to the next process.

[0038] like Figure 4-Figure 5As shown, the limiting column 3110 is fixed on the cup placing connecting piece 3140, and the cup placing connecting piece 3140 is connected to the cup stacking driving structure through the cup stacking driving connecting plate 3150; the cup stacking driving structure includes a transverse cup stacking driving structure 3120 and a longitudinal cup stacking driving structure 3130; the transverse cup stacking driving structure 3120 is connected to the cup stacking driving connecting plate 3150 and drives it to do transverse reciprocating motion.

The present invention takes and places the disposable cups into the gap of the limiting column 3110. When the number of cups is stacked to the set value, the transverse cup stacking driving structure 3120 will drive the cup stacking driving connecting plate 3150, and at the same time drive the cup placing connecting piece 3140 to move horizontally together, and transport the stacked disposable cups to the next process. The driving device adopts a servo motor, which can more accurately control the position movement of the cup stacking driving connecting plate 3150, and can also provide suitable torque power for its movement, so as to use more and heavier products to stack, improve the output value, and have better practicality. In addition, the use of a guide rail can reduce the friction force of the connecting plate movement, reduce the load of the servo motor, and at the same time, further prevent the cup stacking driving connecting plate 3150 from displacement deviation, thereby improving the mechanical accuracy. The longitudinal cup stacking driving structure 3130 is respectively connected to the cup stacking driving connecting plate 3150 and the cup placing connecting piece 3140, and drives the cup placing connecting piece 3140 to do longitudinal reciprocating motion. The longitudinal cup stacking driving structure 3130 includes a longitudinal cup stacking driving device 3131 and a longitudinal cup stacking guiding device 3132. The longitudinal cup stacking driving device 3131 is respectively connected to the cup stacking driving connecting plate 3150 and the cup placing connecting piece 3140 and drives the cup placing connecting piece 3140 to perform longitudinal reciprocating motion. One side of the longitudinal cup stacking guiding device 3132 is fixedly connected to the cup stacking driving connecting plate 3150, and the other side is slidably connected to the cup placing connecting piece 3140. The transverse driving device and the longitudinal driving device of the present invention are driving motors, and the transverse guiding device and the longitudinal guiding device are guide rails. Since the longitudinal driving device of the present mechanism can drive the cup placing connecting piece 3140 to move up and down, the cup placing connecting pieces 3140 on the left and right sides of the present invention can be staggered up and down to avoid collision during operation, and at the same time, the mechanical installation space can be reduced to improve space utilization. At the same time, the present invention has a simple structure and obvious production efficiency, which is conducive to daily maintenance and reduces production costs.

[0039] The transverse cup stacking driving device 3121 and the longitudinal cup stacking driving device 3131 are servo motors, but other driving devices such as air cylinders and oil cylinders can also be used.

The adjustment drive structure includes an adjustment drive motor and an adjustment guide rail, the adjustment drive motor is connected to the adjustment connecting plate 3210 and the cup stacking adjustment member 3230 respectively, one side of the guide rail is fixedly connected to the adjustment connecting plate 3210, and the other side is slidably connected to the cup stacking adjustment member 3230. The present invention can adjust the stacking moving distance of disposable cups by setting a cup position adjustment unit 3200, thereby reducing the occurrence of cup jamming. In addition, a servo motor is used, which is driven by the meshing of belts and gears, so that the position movement of the cup stacking adjustment member 3230 can be more accurately controlled. At the same time, the cup stacking adjustment member 3230 can also be controlled to make fine adjustments after each disposable cup is placed, thereby further reducing the risk of cup jamming. One end of the cup stacking adjustment member 3230 extending into the gap of the limiting column 3110 is a parallel and spaced vertical bar. After the cup stacking machine sucks the disposable cup out of the cup making machine, it is placed on the vertical bar. The cup stacking adjustment member 3230 can adjust the stacking height of the cup according to the number of disposable cups in the limiting column 3110, reduce the moving distance of the disposable cup in the limiting column 3110, thereby reducing the occurrence of cup jamming and improving the quality of the finished product. At the same time, the vertical bar structure is simple, the effect is obvious, it is conducive to daily maintenance, and the maintenance cost is simple.

[0041] The adjustment drive motor is a servo motor, but other drive devices such as air cylinders and oil cylinders can also be used. The adjustment guide rail can also be replaced by other guide devices such as ball screws and guide rods, which are not limited in this application.

The general cup collecting mechanism adopts gravity-type cup collecting, but this method is easy to cause cups to be placed unevenly during the production process and get stuck. In the present invention, after the cup collecting mechanism stacks the disposable cups, the cup stacking mechanism can be docked with the cup collecting bin 4110, and the stacked cups can be pushed and fixed in the cup collecting bin 4110 by using the cup clamping structure 4120 and the longitudinal cup pushing unit 4200, so as to improve the quality and efficiency of the finished product.
