Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and in particular relates to a material handling and conveying system. Background Technology

[0002] The blister packs output by the shearing machine are placed horizontally on the conveyor belt for transport. For a special specification of blister pack, the height is 4mm at the lowest point and 4.8mm at the highest point. In order to minimize the volume of the required packaging box, the blister pack needs to be placed vertically inside the box, and the lowest and highest points of the blister pack inside the box can be staggered. The existing technology lacks an automatic equipment that can realize the blister pack flipping during the transport process and making it vertically staggered for transport. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a material handling and conveying system with a reasonable layout and stable operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A material handling and conveying system includes a first conveying channel and a second conveying channel. The materials on the first conveying channel and the materials on the second conveying channel are placed in opposite directions. The first conveying channel is connected to a first chute and a first alignment mechanism, and the second conveying channel is connected to a second chute and a second alignment mechanism. The first chute and the second chute are used to flip the horizontally conveyed materials into vertically conveyed materials. The first alignment mechanism and the second alignment mechanism are used to align and convey the materials. The first alignment mechanism and the second alignment mechanism are respectively connected to a conveying mechanism. Buffer mechanisms are provided at positions adjacent to the conveying mechanism for the first alignment mechanism and the second alignment mechanism. The system has a reasonable layout and stable operation.

[0006] As a further improvement to the above technical solution:

[0007] The first and second alignment mechanisms are respectively connected to the first material troughs of adjacent columns on the conveying mechanism, so as to achieve staggered placement and facilitate boxing.

[0008] The material is a blister pack containing at least two pills with a height difference between them. The blister packs on the conveying mechanism are staggered to accommodate the pills with the height difference, thus meeting the compact packaging requirements of blister packs of special specifications.

[0009] The first and second conveying channels are respectively located on both sides of the third conveying channel. At least a first transfer mechanism and a second transfer mechanism are provided above the third conveying channel. The first and second transfer mechanisms are used to transfer materials on the third conveying channel to the first and second conveying channels, and the materials on the first and second conveying channels are placed in opposite directions through the first and second transfer mechanisms. The structure is compact and the layout is reasonable.

[0010] A visual inspection mechanism is provided above the third conveying channel. The visual inspection mechanism is set at the front end of the first and second transfer mechanisms along the material conveying direction to achieve precise control.

[0011] Both the first and second alignment mechanisms include a feeding trough and a pusher plate disposed on the feeding trough. The pusher plate pushes the material to move along the feeding trough. A buffer mechanism is provided at the docking point of the first material trough adjacent to the conveying mechanism on the feeding trough. The buffer mechanism is a brush, which is used to block the material and ensure stable operation of the equipment.

[0012] Both the first and second chutes are equipped with detection switches. The first and second alignment mechanisms are arranged perpendicular to the conveying mechanism, which is a reasonable layout.

[0013] The first conveying channel, the second conveying channel, and the third conveying channel are arranged on the conveyor belt. The first conveying channel and the second conveying channel are each provided with a second material trough. A frame is provided above the conveyor belt. The first transfer mechanism and the second transfer mechanism are arranged on the frame. The layout is reasonable and compact.

[0014] A recycling channel is provided below the first and second alignment mechanisms. The recycling channel is connected to the third conveying channel. The layout is reasonable and compact, which meets the material recycling requirements.

[0015] The first transfer mechanism is used to grab the material on the third conveying channel and rotate it 180 degrees before transferring it to the first conveying channel. The second transfer mechanism is used to grab the material on the third conveying channel and transfer it to the second conveying channel. The layout is reasonable.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model discloses a material handling and conveying system. Materials placed in opposite directions are horizontally conveyed along a first conveying channel and a second conveying channel. They are then rotated 90 degrees by a first chute and a second chute to become vertically conveyed. Since the inlet width of the first and second chutes is approximately the same as the horizontal width of the material, and after the material is rotated 90 degrees, the width of the conveying trough should be approximately the same as the thickness of the material, the first and second alignment mechanisms gather the material and complete the aligned conveying, reducing the spacing between materials. When the material is conveyed to the conveying mechanism, it can enter the first trough. A buffer mechanism is used to buffer the material during conveying, preventing over-rushing and interference with the next alignment action of the alignment mechanism. During the material conveying process, the horizontal conveying of materials placed in opposite directions, the rotation of materials from horizontal to vertical, the gathering and alignment of vertical materials, and the conveying of staggered materials by the conveying mechanism are completed through the conveying channels, chutes, alignment mechanisms, and conveying mechanism. The equipment layout is reasonable, with a wide-to-narrow layout completing the material handling. The equipment layout requires less space, and the buffer mechanism prevents over-rushing of materials from interfering with the next action, ensuring stable equipment operation.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 5 The material handling and conveying system shown includes a first conveying channel 1 and a second conveying channel 2. The materials on the first conveying channel 1 and the materials on the second conveying channel 2 are placed in opposite directions. The materials with opposite placement directions can be output by connecting two sets of shearing machines with opposite front-end material output directions to the first conveying channel 1 and the second conveying channel 2 respectively. Alternatively, they can be output by connecting a third conveying channel 10 to a single shearing machine. Then, the materials on the third conveying channel 10 are transferred to the first conveying channel 1 and the second conveying channel 2 respectively by a transfer mechanism 3. The transfer mechanism 3 can be configured to rotate 180 degrees on the horizontal plane when the materials are placed on the first conveying channel 1 so that the materials face the opposite direction, and not rotate when the materials are placed on the second conveying channel 1 so that the materials face the same direction. This achieves the opposite placement directions of the materials on the first conveying channel 1 and the second conveying channel 2.

[0026] The first conveying channel 1 connects to the first chute 4 and the first alignment mechanism 5. The second conveying channel 2 connects to the second chute 6 and the second alignment mechanism 7. The first chute 4 and the second chute 6 are used to flip the horizontally conveyed material into a vertically conveyed material. The first alignment mechanism 5 and the second alignment mechanism 7 are used to align and convey the material. The first alignment mechanism 5 and the second alignment mechanism 7 are respectively connected to the conveying mechanism 8. The first alignment mechanism 5 and the second alignment mechanism 7 are provided with a buffer mechanism 15 near the conveying mechanism 8.

[0027] The material is rotated 90 degrees by the first chute 4 and the second chute 6 to become vertically conveyed. Since the inlet width of the first chute 4 and the second chute 6 is basically the same as the horizontal width of the material, and after the material is rotated 90 degrees, the width of the conveying trough 13 is basically the same as the thickness of the material, the first alignment mechanism 3 and the second alignment mechanism 4 gather the material and reduce the distance between the materials to complete the alignment conveying. When the material is conveyed to the conveying mechanism 8, the arrangement is more compact, and the material can enter the first trough. The buffer mechanism 15 is used to buffer the material during conveying to prevent the material from over-rushing and interfering with the next alignment action of the alignment mechanism. During the material conveying process, the horizontal conveying of materials with opposite placement directions, the material being rotated from horizontal to vertical, the vertical materials being gathered and aligned, and the staggered materials being conveyed by the conveying mechanism are completed through the conveying channel, chute, alignment mechanism and conveying mechanism. The equipment layout is reasonable, with a layout from wide to narrow, and the space required for the equipment layout is small. The setting of the buffer mechanism 15 prevents the material from over-rushing and interfering with the next action process, ensuring the stable operation of the equipment.

[0028] In one embodiment, both the first aligning mechanism 5 and the second aligning mechanism 7 include multiple rows of conveying troughs 13 for conveying materials one-to-one to the first trough 9 of the third conveying channel 10. To ensure the materials are staggered and placed vertically, the number of conveying troughs 13 on the first aligning mechanism 5 and the second aligning mechanism 7 is the same, and the number of conveying troughs 13 should be a multiple of the amount of material to be loaded in a box. For example, when a packaging box needs to hold 20 tablets, the number of conveying troughs 13 can be set to 5 or 10. In this case, the tablets on the first aligning mechanism 5 are pushed to the 1st to 5th, or 1st to 10th, of the first trough 9, and the tablets on the second aligning mechanism 7 are pushed to the 6th to 10th, or 11th to 12th, of the first trough 9. This allows the tablets in a packaging box to be staggered in a regular manner, so that the thicker end and the thinner end can be staggered and compressed, thus using a smaller packaging box.

[0029] In another embodiment, the first alignment mechanism 5 and the second alignment mechanism 7 are respectively connected to the first material troughs 9 of adjacent different columns on the conveying mechanism 8. For example, the material trough 13 of the first alignment mechanism 5 is aligned with the odd-numbered columns of the first material troughs 9 on the conveying mechanism 8, and the material trough 13 of the second alignment mechanism 7 is aligned with the even-numbered columns of the first material troughs 9 on the conveying mechanism 8. In this way, two adjacent materials are placed alternately, which can save packaging box space while satisfying the vertical staggered placement, and can be used for more packaging specifications, such as the situation where a box contains 25 or 27 blister packs, which is not convenient to set multiple columns. Secondly, since the first alignment mechanism 5 and the second alignment mechanism 7 only need to align the first material troughs 9 separated by one empty material trough, the degree of convergence of the materials finally output by the first alignment mechanism 5 and the second alignment mechanism 7 is lower. Therefore, the length of the first alignment mechanism 5 and the second alignment mechanism 7 can be reduced, and the layout is compact and reasonable.

[0030] The material is a blister pack 21, which contains at least two pills with a height difference between them. The blister packs on the conveying mechanism 8 are staggered so that the pills with height differences are also staggered. The feeding and conveying system is suitable for blister packs of special specifications, and can also be used for blister packs where the pills do not have a height difference, conveying them vertically to the cartoning machine. The special specifications of the blister pack 21 listed in this solution include one large pill 22 and three small pills 23. The blister pack 21 is 105mm long, 40mm wide, and has a minimum height of 5mm and a maximum height of 5.8mm. It can be fed and conveyed by the feeding and conveying system of this solution.

[0031] The first conveying channel 1 and the second conveying channel 2 are respectively located on both sides of the third conveying channel 10. At least a first transfer mechanism 3 and a second transfer mechanism 11 are provided above the third conveying channel 10. The first transfer mechanism 3 and the second transfer mechanism 11 are used to transfer materials on the third conveying channel 10 to the first conveying channel 1 and the second conveying channel 2. The layout is reasonable and compact, making full use of space, reducing the movement path length of the transfer mechanism, and through the first transfer mechanism 3 and the second transfer mechanism 11, the materials on the first conveying channel 1 and the second conveying channel 2 are placed in opposite directions, the transfer rhythm is faster, and speed matching is achieved.

[0032] A vision inspection mechanism 12 is provided above the third conveying channel 10. The vision inspection mechanism 12 is set at the front end of the first transfer mechanism 3 and the second transfer mechanism 11 along the material conveying direction. The controller controls the material transfer process through the detection signal of the vision inspection mechanism 12, reducing the occurrence of material gaps at the input end and realizing automated control.

[0033] Both the first alignment mechanism 5 and the second alignment mechanism 7 include a conveying trough 13 and a pusher plate 14 disposed on the conveying trough 13. The pusher plate 14 pushes the material along the conveying trough 13. A buffer mechanism 15 is provided at the docking point of the first material trough 9 adjacent to the conveying mechanism 8 on the conveying trough 13. The buffer mechanism 15 is a brush, which is used to block the material. The brush is located at the last stopping position of the conveying trough 13. When the pusher plate 14 pushes the material at the last stopping position of the conveying trough 13 into the first material trough 9, the previous pusher plate 14 at the receiving end pushes the material from the previous station into the last stopping position of the conveying trough 13. Since the surface of the medicine plate is relatively hard and smooth, the medicine plate is often pushed too far when the pusher plate 14 pushes the medicine plate, causing the medicine plate to be pressed by the returning pusher plate 14. The brush is used to block the material. The brush is relatively soft, which can ensure that the medicine plate does not go too far and that the medicine plate can smoothly pass through the conveying trough 13 into the first material trough 9 under the action of the pusher plate 14.

[0034] Both the first chute 4 and the second chute 6 are equipped with detection switches 16. The first alignment mechanism 5 and the second alignment mechanism 7 are set perpendicular to the conveying mechanism 8. The pusher plate 14 pushes the material according to the detection signal of the detection switch 16 to ensure that the material is conveyed intermittently for alignment. The detection switch 16 is a photoelectric switch.

[0035] The first conveying channel 1, the second conveying channel 2, and the third conveying channel 10 are set on the conveyor belt 17. They can be set on the same conveyor belt or on different conveyor belts, and can be adjusted according to the material conveying speed. The first conveying channel 1 and the second conveying channel 2 are intermittent conveying to match the rear-end alignment and boxing process. The first conveying channel 1 and the second conveying channel 2 are each equipped with a second material trough 18 to ensure uniform material spacing and facilitate rear-end alignment. A frame 19 is set above the conveyor belt 17. The first transfer mechanism 3 and the second transfer mechanism 11 are set on the frame 19, making full use of the upper space and resulting in a compact layout.

[0036] Below the first alignment mechanism 5 and the second alignment mechanism 7, there is a recycling channel 20. The recycling channel 20 is connected to the third conveying channel 10. Untransferred materials left on the third conveying channel 10 are recycled through the recycling channel 20. There is a height difference between the third conveying channel 10 and the recycling channel 20. The materials on the third conveying channel 10 fall onto the recycling channel 20 through a chute. The recycling channel 20 is a conveyor belt. The discharge direction of the recycling channel 20 is the same as the discharge direction of the conveying mechanism 8, which facilitates subsequent connection with other equipment or manual operation.

[0037] The first transfer mechanism 3 is used to grab the material on the third conveying channel 10 and rotate it 180 degrees before transferring it to the first conveying channel 1. The second transfer mechanism 11 is used to grab the material on the third conveying channel 10 and transfer it to the second conveying channel 2. This achieves one-to-one matching for material transfer, making the control program setting and equipment debugging simpler. The first transfer mechanism 3 consists of two spider arms set along the first conveying channel 1, and the second transfer mechanism 11 consists of two spider arms set along the second conveying channel 2. The spider arms are staggered along the conveying channels to avoid interference, resulting in a more compact and reasonable layout.

Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
