Description

Technical Field

[0001] The utility model particularly relates to an automatic rejecting mechanism for unqualified products on a high-speed production line. Background Art

[0002] With the advancement of science and technology and the needs of social development, more industries choose to replace manual operations with machinery in order to save resources and reduce costs. With the continuous development of productivity, simple mechanization can no longer meet the needs of complex production processes, and thus develop in the direction of mechanical automation and artificial intelligence.

[0003] In the prior art, products generally go through a weighing process before packaging and shipment, and unqualified products with unqualified weight are screened out by weighing. For example, a dynamic weighing device compatible with marking and detection functions disclosed in Chinese Patent Announcement No. CN220743579U discloses a support mechanism and a transmission mechanism for transmitting medicine boxes, wherein the transmission mechanism includes a first transmission belt, a second transmission belt and a third transmission belt arranged in a straight line, and a weighing mechanism for detecting the weight of the medicine box is arranged below the second transmission belt; a laser marking mechanism and a visual detection mechanism are arranged on the support mechanism corresponding to the first transmission belt and in sequence along its transmission direction; a rejection mechanism for rejecting the medicine box from the transmission mechanism is arranged on the support mechanism corresponding to the third transmission belt. However, there is no specific identification for the unqualified weight that is screened out, that is, the weight exceeding the shipping standard or below the shipping standard will be concentrated and rejected from the same area, causing confusion, so that the staff needs to re-check and re-weigh to screen, which is difficult to meet the needs of automated production. Utility Model Content

[0004] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a mechanism for automatically removing defective products on a high-speed production line.

[0007] In one embodiment, the cutting mechanism includes a first cylinder arranged on the flap, a connecting seat is arranged on the driving shaft of the first cylinder, a cutting knife is arranged on the connecting seat, and the cutting knife is driven by the first cylinder to move and protrude outward from the lower end of the flap as the connecting seat is driven.

[0009] In one embodiment, a torsion spring is provided on the rotating shaft between the frame and the flap, a limit plate is provided on one side of the frame, and the flap is maintained in a vertical connection state tightly attached to one side of the limit plate by the force of the torsion spring.

[0010] In one embodiment, an L-shaped air duct is provided in the flap, and an air hole connected to the L-shaped air duct is provided on the side of the flap opposite to the pushing mechanism, and a one-way air intake valve that can only intake air in one direction to the L-shaped air duct is provided in the air hole, and one end of the L-shaped air duct is connected to the air outlet end of an external high-pressure blower through a hose.

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0026] like Figures 1 to 8The embodiment of the utility model shown preferably provides an automatic rejection mechanism for unqualified products on a high-speed production line, including a frame 1, on which a feeding conveyor line 2, a weighing conveyor line 3 and a sorting conveyor line 4 are sequentially arranged, and a drop port 5 and a pushing mechanism 6 capable of pushing unqualified products into the drop port 5 are respectively arranged on the left and right sides of the sorting conveyor line 4, and a first identification mechanism 7 and a second identification mechanism 8 are respectively arranged at the drop port 5 on the frame 1, and the first identification mechanism 7 and the second identification mechanism 8 have the same structure, and a driving member 9 capable of driving the first identification mechanism 7 and the second identification mechanism 8 to flip is respectively arranged on the frame 1;

[0027] Specifically, the feeding conveyor line, weighing conveyor line and sorting conveyor line are all relatively mature existing technologies, and their structural principles will not be described in detail here. The weighing conveyor line is used to weigh and detect the shipped products, and then the sorting conveyor line is combined with the pushing mechanism to push the products with unqualified weight to the drop port to remove the defective products, and the first identification mechanism and the second identification mechanism at the drop port are used to stick different colored tapes on the defective products for identification and distinction (that is, the product weight exceeding the shipping standard weight is one color, and the product weight below the shipping standard weight is another color), so as to achieve a clear visual distinction between defective products and avoid the problem of confusion caused by the need for subsequent staff to re-inspect and screen;

[0028] Furthermore, the first identification mechanism and the second identification mechanism are both provided with driving components, so that the first identification mechanism or the second identification mechanism can be flipped relative to the frame by the driving components, so that the first identification mechanism and the second identification mechanism can select a pair of defective products for identification.

[0029] Furthermore, the first identification mechanism 7 includes a flap 71 rotatably arranged on the frame 1, a reel 72 arranged on the frame 1, and a cutting mechanism 73 arranged on one side of the flap 71; wherein, a tape roll 74 is sleeved on the reel 72, and a guide roller 75 is arranged on the side of the flap 71 opposite to the cutting mechanism 73, and a guide gap is formed between the flap 71 and the guide roller 75, one end of the tape roll 74 passes through the guide gap and covers one side of the flap 71, and the adhesive back surface of one end of the tape roll 74 is in contact with the side wall of the flap 71.

[0030] Specifically, Figure 5 As shown, when the defective product 99 is pushed to the material outlet by the pushing mechanism, one side of the defective product 99 contacts the flap 71. At this time, the tape roll 74 covering one side of the flap 71 is attached to the front side of the defective product 99, and the defective product 99 is continuously moved by the pushing mechanism. Figure 6As shown, because one end of the tape roll 74 is fixed to the defective product 99, when the defective product 99 continues to move, the tape roll 74 is unwound and continues to be pasted along the upper side of the defective product 99. When the defective product 99 completely passes the flap 71, the sensor senses and sends a signal to drive the cutting mechanism to work. The cutting mechanism cuts the end of the tape roll protruding below the lower end of the flap, thereby achieving the goal of pasting colored tape on the defective product 99 for marking.

[0031] Furthermore, the cutting mechanism 73 includes a first cylinder 76 disposed on the flap 71, a connecting seat 77 is disposed on the driving shaft of the first cylinder 76, a cutter 78 is disposed on the connecting seat 77, and the cutter 78 is driven by the first cylinder 76 to move and protrude outward from the lower end of the flap 71 along with the connecting seat 77. Specifically, Figure 6 As shown, the connecting seat is driven to move by the first cylinder, so that the cutter on the connecting seat moves accordingly and presses against one end of the tape roll, thereby realizing the cutting and separation of the tape roll.

[0032] Further, the driving member 9 includes a second cylinder 91 disposed on the frame 1, a first push plate 92 is disposed on the driving shaft of the second cylinder 91, the flap 71 is rotatably connected to the frame 1 via a rotating shaft 93, a connecting rod 94 is fixedly connected to the rotating shaft 93, and the first push plate 92 is driven by the second cylinder 91 to move and press against one side of the connecting rod 94. Specifically, the first push plate is driven to move by the second cylinder so that the first push plate moves to press against the connecting rod, and then the connecting rod rotates around the rotating shaft, thereby driving the flap to flip, and realizing the flipping of the first identification mechanism or the second identification mechanism.

[0033] Furthermore, a torsion spring 95 is provided on the rotating shaft 93 between the frame 1 and the flap 71, and a limit plate 96 is provided on one side of the frame 1. The flap 71 is kept in a vertical connection state closely attached to one side of the limit plate 96 by the force of the torsion spring 95. When the driving member is pressed against the connecting rod without power, the flap can be kept in a vertical state with the force of the torsion spring and in cooperation with the limit plate, so that the adhesive tape covering one side of the flap can be attached to the front side of the defective product. At the same time, when the flap is turned over by the defective product, the lower end of the flap can be kept in contact with the defective product, so that the adhesive tape can be flatly swept and tightly attached to the defective product.

[0034] Furthermore, the flap 71 has an L-shaped air duct 51, and a wind hole 52 connected to the L-shaped air duct 51 is provided on the side of the flap 71 opposite to the material pushing mechanism 6, and a one-way air intake valve 53 is provided in the air hole 52, which can only intake air in one direction to the L-shaped air duct 51, and one end of the L-shaped air duct 51 is connected to the air outlet of an external high-pressure blower through a hose. Specifically, the high-pressure blower delivers high-pressure gas into the L-shaped air duct, thereby generating negative pressure at the air intake end of the one-way air intake valve of the wind hole, so that the adhesive backing surface of one end of the tape roll can fit with the side of the flap.

[0035] Furthermore, guide plates 54 are symmetrically arranged on both sides of the drop opening 5, and the flap 71 is located within the gap formed by the two guide plates 54. The two guide plates are used to guide and push defective products, so that defective products can be easily matched with the flap.

[0036] Furthermore, the pushing mechanism 6 includes a third cylinder 61 disposed on the frame 1 and a second pushing plate 62 disposed on the driving shaft of the third cylinder 61 . The second pushing plate 62 is driven by the third cylinder 61 to perform reciprocating telescopic movement toward the blanking port 5 .

[0037] Furthermore, the color of the tape roll 74 in the first identification mechanism 7 and the color of the tape roll 74 in the second identification mechanism 8 are different colors.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
