Description

Technical Field

[0001] The invention relates to a detection device for capsules, which can be used to perform defect inspection on capsules and sort out capsules with unqualified weight and defective appearance. Background Art

[0002] Traditional capsule inspection is to sort out defective products by manual visual inspection. The capsules are poured into the feeding funnel and scattered on the frosted glass with backlight. The inspectors use their eyes to pick out defective capsules by hand under the backlight. The working state of the inspectors has a great impact on the inspection results. In addition, this working method has low inspection efficiency, high cost and high labor intensity. Manual labor not only wastes a lot of labor resources, but also cannot fundamentally guarantee product quality.

[0003] A Chinese invention patent with publication number "CN103940825B" discloses an all-round capsule detection device and a corresponding detection method, including: a conveying device, a body imaging device, a first end face imaging device, a second end face imaging device, a body illumination light source, a first group of end face illumination light sources, a second group of end face illumination light sources, a first field of view angle adjustment device and a second field of view angle adjustment device, and an image detection device. The conveying device carries a number of capsules to be tested and can drive the capsules to be tested to move in a predetermined direction; the conveying device includes a number of rotatable rollers arranged parallel to each other, the rotatable rollers have respective rotation axes and can rotate around their respective rotation axes, the rotatable rollers are connected to each other through a linking device to form an annular conveying chain, and the annular conveying chain can revolve around two spaced rollers.

[0004] However, the above capsule detection equipment still has the following defects: 1. The conveying device of the capsule detection device will cause the capsule to rotate continuously. The capsule will rotate continuously during the conveying process. When the capsule leaves the detection range of the detection device, the capsule will rub against the rotating roller continuously, and the capsule will be easily damaged, which greatly increases the unqualified rate of the product. Second, the above-mentioned capsule inspection equipment can only inspect the packaging of capsules, but cannot inspect the quality of capsules at the same time. If the capsules need to be weighed, the capsules can only be transferred to the quality inspection device for inspection, which is relatively cumbersome.

[0005] 3. The conveying device of the above-mentioned capsule detection device can only transmit a single capsule at intervals and cannot detect multiple capsules at the same time. The detection efficiency needs to be improved. Summary of the invention

[0006] The purpose of the present invention is to provide a capsule detection device to solve the above problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a capsule detection device, including a fixed plate, on which an arranging device, a conveying device, and a detection device are arranged, the arranging device is arranged at one end of the conveying device, the detection device is arranged above the conveying device, the conveying device includes a conveying plate, a plurality of conveying grooves spaced apart on the conveying plate, the conveying plate is fixedly connected to the fixed plate and inclined to the horizontal direction, the conveying groove is located below the detection device and has an opening penetrating the conveying plate, a accommodating groove is provided on the side of the conveying plate away from the conveying groove, the accommodating groove is located within the detection range of the detection device, a rotating device is provided below the accommodating groove, and the rotating device realizes the rotation of the capsule during the detection process through the opening.

[0008] By adopting the above technical solution: the capsules enter the conveying device in an orderly manner through the arranging device, the conveying plate of the conveying device has a certain angle with the horizontal direction, so that the capsules can stably slide into the conveying groove, the receiving groove of the conveying device can stably connect the rotating device to the bottom of the detection device, and the opening in the conveying groove enables the rotating device to come into contact with the capsules in the conveying groove, thereby realizing the circumferential rotation of the capsules. The detection device above the conveying plate performs 360-degree all-round detection on the capsules on the conveying device. When the capsule leaves the detection range of the detection device, the capsule disengages from the rotating device, stops rotating, and continues to move along the displacement direction of the conveying device.

[0009] The above-mentioned capsule detection equipment can be further configured as follows: the rotating device includes a fixed frame, a supporting tube, and a rotating belt. Fixed grooves are opened at both ends of the fixed frame, the supporting tube is arranged in the fixed groove and clamped on the fixed frame, and the rotating belt is connected to the fixed frame through the gaps between the supporting tubes at both ends. The rotating belt can stably contact with the capsule and drive the capsule to rotate.

[0010] By adopting the above technical solution: the rotating device passes through the fixing groove on the fixing frame and the supporting tube is arranged in the fixing groove, the supporting tube can be laterally displaced in the fixing groove so that the tightness of the rotating belt can be adjusted, so that the rotating belt and the capsule are in stable contact and the use capacity of the rotating device is prevented from being reduced due to the rotating belt being too tight or too loose.

[0011] The above-mentioned capsule detection equipment can be further configured as follows: the arranging device includes a storage bin, a sorting bin, and a feeding bin; the storage bin is connected to one end of the sorting bin, and the other end of the sorting bin is gap-matched with the feeding bin; the feeding bin is provided with a plurality of feeding holes arranged at intervals; a plurality of weighing devices are provided below the feeding bin; the weighing devices include a weighing bin and a weight sensor; the weighing bin is provided above the weight sensor, and the weighing bin corresponds to the feeding port.

[0012] By adopting the above technical solution: the storage bin can store a large number of capsules, the capsules are sorted by the sorting bin and fall into the feeding holes in the feeding bin, the feeding bin rotates to drop the capsules into the weighing bin, the weight sensor detects the weight of the capsules in the weighing bin and then sends the capsules to the conveying device, if the quality of the capsules does not meet expectations, the waste rejection device at the rear end of the conveying device can reject the unqualified capsules, thereby ensuring the consistency of the capsule quality.

[0013] The capsule detection device can be further configured as follows: a waste rejection device is provided at the rear end of the conveying plate, the waste rejection device includes a plurality of waste rejection rods, a waste rejection opening is provided at the tail end of the conveying slot, the waste rejection rods are arranged in the waste rejection opening, and the waste rejection rods are connected to the detection device.

[0014] By adopting the above technical solution: multiple conveying grooves can improve the conveying efficiency of capsules, and at the same time, the reject rod of the rejecting device is arranged in the reject opening at the tail of the conveying groove, and the reject rod will not hinder the movement of the capsules in the conveying groove. When the unqualified capsules identified by the detection device move to the reject rod, the reject rod receives the signal sent by the detection device, and the reject rod pops out to throw the unqualified capsules to the recycling area, which is convenient and quick.

[0015] The capsule detection equipment can be further configured as follows: the detection device includes a plurality of industrial cameras arranged above the conveying slot and refractors arranged on both sides of the industrial cameras, the industrial cameras are connected to the machine vision system, and the refractors are arranged at a certain angle to the conveying slot to focus light in the conveying slot.

[0016] By adopting the above technical solution: the industrial camera has high performance, reliability and durability, and can adapt to various needs. Therefore, the industrial camera is used as the input end of the machine vision system to input the capsule image on the conveying device into the system in high definition, so that the system's detection accuracy of capsule packaging is significantly improved. At the same time, the refractor can converge the light on the conveying device under the industrial camera to provide sufficient light for the machine vision system, so that the contrast of the capsule packaging is improved, which can effectively improve the detection accuracy.

[0017] The capsule detection device can be further configured as follows: the refractor is provided with a certain angle, a light source is provided at the edge of the refractor, and the refractor can provide multi-angle shooting for the industrial camera.

[0018] By adopting the above technical solution: the light source is placed on the edge of the refractor, and the refractors on both sides of the industrial camera reflect the light source to each other and converge the light of the light source on the conveying device, so that the brightness of the conveying device is improved. At the same time, the industrial camera can realize multi-angle shooting of the capsule through the refractor, thereby realizing effective comparison of the capsule packaging.

[0019] The capsule detection device can be further configured as follows: a rotating plate is provided in the storage bin, the blades of the rotating plate are in contact with the inner wall of the storage bin, a driving rod is provided in the middle of the rotating plate, and an opening is provided on the fixed plate for the driving rod to pass through.

[0020] By adopting the above technical solution: the rotating plate divides the storage bin into multiple chambers. When the capsules in the chamber move to the top of the sorting bin, since the chamber is isolated by the rotating plate, a large number of capsules will not accumulate at the feed inlet of the sorting bin, thereby improving the stability of the equipment.

[0021] The beneficial effects of the present invention are: 1. The rotating device is only set within the detection range of the detection device. The rotating device can realize the circumferential rotation of the capsule, thereby improving the overall recognition of the detection device on the outer packaging of the capsule, effectively identifying unqualified capsules, and improving the packaging quality of the capsule. When the capsule leaves the detection range of the detection device, the capsule stops rotating to prevent the capsule packaging from being damaged due to the continuous rotation of the capsule.

[0022] Second, by setting a weighing device under the arrangement device, the quality of the capsules can be effectively controlled. The light or heavy capsules are classified as unqualified products and are removed and collected by the removal device, thus ensuring the consistency of the capsule quality.

[0023] Third, each device is fixed by a fixing plate, and each device is arranged in coordination with each other, so that the overall volume of the equipment is small, and it can be effectively integrated into various capsule production equipment, and the structure of each device is relatively simple, and maintenance is convenient and quick.

[0027] like Figures 1 to 9 A capsule detection device shown in the figure includes a fixed plate 1, on which an arranging device 2, a conveying device 3, and a detection device 4 are provided. The arranging device 2 is arranged at one end of the conveying device 3, and the detection device 4 is arranged above the conveying device 3. The conveying device 3 includes a conveying plate 31 and a plurality of conveying grooves 32 spaced apart on the conveying plate 31. The conveying plate 31 is fixedly connected to the fixed plate 1 and inclined to the horizontal direction. The conveying groove 32 is located below the detection device 4 and is provided with an opening 34 that passes through the conveying plate 31. A receiving groove 33 is provided on the side of the conveying plate 31 away from the conveying groove 32. The receiving groove 33 is located within the detection range of the detection device 4. A rotating device 6 is provided below the receiving groove 33. The rotating device 6 realizes the rotation of the capsule during the detection process through the opening 34. The capsules enter the conveying device 3 in an orderly manner through the arranging device 2. The conveying plate 31 of the conveying device 3 has a certain angle with the horizontal direction, so that the capsules can stably slide into the conveying groove 32. The receiving groove 33 of the conveying device 3 can stably connect the rotating device 6 to the bottom of the detection device 4. The detection device 4 above the conveying plate 31 detects the capsules on the conveying device 3. The rotating device 6 can rotate the capsules located in the detection section in a circumferential direction. The detection device 4 can perform 360-degree all-round detection on the packaging of the capsules. When the capsule leaves the detection range of the detection device 4, the capsule disengages from the rotating device 6, stops rotating, and continues to move along the displacement direction of the conveying device 3.

[0028] like Figures 1 to 7The rotating device 6 shown includes a fixing frame 61, a supporting tube 62, and a rotating belt 63. The fixing frame 61 is provided with fixing grooves 611 at both ends. The supporting tube 62 is arranged in the fixing grooves 611 and is clamped on the fixing frame 61. The rotating belt 63 is connected to the fixing frame 61 through the gaps between the supporting tubes 62 at both ends. The rotating belt 63 can stably contact with the capsule and drive the capsule to rotate. The rotating device 6 passes through the fixing groove 611 on the fixing frame 61 and arranges the supporting tube 62 in the fixing groove 611. The supporting tube 62 can be laterally displaced in the fixing groove 611 so that the tightness of the rotating belt 63 can be adjusted, so that the rotating belt 63 is in stable contact with the capsule and prevents the rotating belt 63 from being too tight or too loose, which causes the use capacity of the rotating device 6 to decrease.

The feeding bin 23 rotates and drops the capsules into the weighing bin 71. The weight sensor 72 performs weight detection on the capsules in the weighing bin 71 and then sends the capsules into the conveying device 3. If the quality of the capsules does not meet expectations, the rejecting device 5 located at the rear end of the conveying device 3 can reject the unqualified capsules, thereby ensuring the consistency of the capsule quality.

At the same time, the reject rod 51 of the reject device is arranged in the reject opening 35 at the rear end of the conveying slot 32. The reject rod 51 will not hinder the capsules moving in the conveying slot 32. When the unqualified capsules identified by the detection device 4 move to the reject rod 51, the reject rod 51 receives the signal sent by the detection device 4, and the reject rod 51 pops up to throw the unqualified capsules to the recycling place, which is convenient and quick.

[0031] The detection device 4 includes a plurality of industrial cameras 41 arranged above the conveying slot 32 and refractors 42 arranged on both sides of the industrial camera 41.

The industrial camera 41 has high performance, reliability and durability, and can meet various needs. Therefore, the use of the industrial camera 41 as the input end of the machine vision system can input the capsule image on the conveying device 3 into the system in high definition, so that the system can significantly improve the detection accuracy of the capsule packaging. At the same time, the refractors 42 can focus the light on the conveying device 3 below the industrial camera 41 to provide sufficient light for the machine vision system, so that the contrast of the capsule packaging is improved, which can effectively improve the detection accuracy.

[0032] The refractor 42 is provided with a certain angle, and a light source is provided at the edge of the refractor 42, so that the refractor 42 can provide multi-angle shooting for the industrial camera 41. The light source is placed at the edge of the refractor 42, and the refractors 42 located on both sides of the industrial camera 41 reflect the light source to each other and converge the light of the light source on the conveying device 3, so that the brightness of the conveying device 3 is improved. At the same time, the industrial camera 41 can realize multi-angle shooting of the capsule through the refractor 42, thereby realizing effective comparison of the capsule packaging.
