[0017] Beneficial effects:
[0018] 1. The utility model cooperates with the locking cylinder and the first photoelectric sensor. When the first photoelectric sensor detects that the positioning tool is transported into place by the conveying belt, it sends an electrical signal to the locking cylinder, and the locking cylinder is started to fix the positioning tool and the lifting plate, thereby avoiding relative displacement between the positioning tool and the lifting plate during the subsequent lifting process.

[0021] 4. In the utility model, when the first photoelectric sensor senses that the positioning tooling has reached the specified position on the conveyor belt, the locking cylinder extends to drive the positioning pin to extend and then pass through the positioning hole to fix the positioning tooling.

In this way, when the lifting plate drives the positioning tooling to move in the vertical direction, it will not produce relative movement with the lifting plate, and can stably and reliably carry the product to prevent the product from falling. The locking structure adopted by the locking cylinder is simple and low-cost.
[0022] 5. The utility model can not only improve the transportation stability and accuracy of products transported in a lifting state, but also determine whether the placement state of the product on the positioning tooling is horizontal, and has high practical value in the application of multi-layer product conveyor lines.

Unless otherwise defined, the technical terms or scientific terms used herein should be the usual meanings understood by people with general skills in the field to which the utility model belongs.

[0033] During the lifting process, the product generates inertia when moving to the lifting device due to the fast transportation speed of the conveyor belt, making it difficult to position on the lifting device, and may fall during the lifting process, resulting in the product not being accurately transported to the required location, affecting the normal progress of subsequent processes.
[0034] Therefore, in order to solve the above-mentioned problems, the utility model provides a product conveying and lifting device which can timely position the product and prevent the product from falling during the lifting process and is suitable for a conveying line containing multiple layers of products.
[0035] See also Figures 1 to 3 As shown, the embodiment of the utility model provides a product conveying and lifting device, including a vertical guide rail 3, a lifting cylinder 4, a positioning tool 1, a conveying belt 8, a locking cylinder 2, a photoelectric sensor and a lifting plate;
[0036] The lifting plate is provided with the conveying belt 8 and the locking cylinder 2. The conveying belt 8 is used to horizontally transport the positioning tool 1. The locking cylinder 2 is provided on the lifting plate on both sides of the horizontal transport direction of the positioning tool 1. When the positioning tool 1 is transported onto the conveying belt 8, it is used to lock the positioning tool 1.
[0037] The lifting plate is connected to the lifting cylinder 4, and the lifting cylinder 4 drives the lifting plate to move up and down along the vertical guide rail 3;
[0038] The photoelectric sensor includes a first photoelectric sensor 10 and a second photoelectric sensor 5. The first photoelectric sensor 10 is provided on the lifting plate to detect whether the positioning tool 1 is transported into place in the horizontal direction. The first photoelectric sensor 10 is connected to the locking cylinder 2 by signal. The second photoelectric sensors 5 are provided on both sides of the upper end and the bottom end of the vertical guide rail 3 to detect whether the positioning tool 1 is transported into place in the vertical direction.
[0039] Through the cooperation of the locking cylinder 2 and the first photoelectric sensor 10, when the first photoelectric sensor 10 detects that the positioning tool 1 is transported into place by the conveyor belt, it sends an electrical signal to the locking cylinder 2, and the locking cylinder 2 is started to fix the positioning tool 1 to the lifting plate, thereby avoiding relative displacement between the positioning tool 1 and the lifting plate during the subsequent lifting process. The positioning tool 1 itself is a supporting fixture for the product, and the product can be prevented from falling along with the positioning tool 1 during the lifting process.
[0040] By respectively arranging the second photoelectric sensors 5 at the upper end and the bottom end of the vertical guide rail 3, it is possible to timely detect whether the positioning tool 1 is transported to the designated position, which is beneficial to the accurate transportation of products on the multi-layer product conveyor line.
[0041] In some embodiments of the utility model, the lifting plate includes a bottom plate and side plates relatively arranged on both sides of the bottom plate, and a belt support plate 11 is provided on the side plate. The belt support plate 11 is arranged between the front and rear rotating shafts that drive the conveyor belt 8 to move, and is used to provide support for the conveyor belt 8. In this way, for a conveyor belt 8 with a longer length, it can be ensured that the middle position of the conveyor belt 8 will not sag due to long-term gravity, thereby improving the stability of product transportation.
[0042] In some embodiments of the utility model, the locking cylinder 2 is provided on the side of the side plate away from the positioning tooling 1, and the front end of the locking cylinder 2 is provided with a positioning pin, and the side plate is provided with a through hole for the positioning pin to pass through. The side of the positioning tooling 1 is provided with a positioning hole, and the first photoelectric sensor 10 is connected with the locking cylinder 2 signal. When the first photoelectric sensor 10 senses that the positioning tooling 1 has reached the specified position on the conveyor belt 8, the locking cylinder 2 extends to drive the positioning pin to extend out and thus penetrate into the positioning hole to fix the positioning tooling 1. The positioning pin passes through the through hole on the lifting plate and then penetrates into the positioning hole on the positioning tooling 1, effectively realizing the fixation between the positioning tooling 1 and the lifting plate. In this way, when the lifting plate drives the positioning tooling 1 to move in the vertical direction, it will not produce relative movement with the lifting plate, and can stably and reliably carry the product to prevent the product from falling. The locking structure adopted by the locking cylinder 2 is simple and low in cost.
[0043] In some embodiments of the utility model, a buffer 6 is provided on the lifting plate and the vertical guide rail 3 to prevent the entire product conveying and lifting device from violent collision during movement and to play a buffering role. The buffer 6 can be set at multiple different positions on the lifting plate and the vertical guide rail 3.
[0044] In some embodiments of the present invention, the buffer 6 is a buffer spring with good shock absorption effect and low cost.
[0045] In some embodiments of the present invention, the rotating shaft that drives the conveyor belt 8 is driven by a motor 7. The motor 7 is accommodated in a concave space surrounded by the bottom plate and the side plate and is located below the positioning tool 1, thereby reducing the volume of the product conveying and lifting device.
[0046] In some embodiments of the utility model, the buffer 6 on the vertical guide rail 3 is close to the second photoelectric sensor 5. Since the second photoelectric sensor 5 is used to detect whether the lifting plate has reached the specified position, the second photoelectric sensor 5 is arranged at a position close to the specified position that the lifting plate should reach. The lifting plate at this position is in a start-stop switching state. At this time, the lifting plate has the maximum acceleration and is most likely to have a violent collision. Therefore, the buffer 6 is arranged near the second photoelectric sensor 5, which is conducive to timely buffering.
[0047] In some embodiments of the utility model, the photoelectric sensor further includes a third photoelectric sensor 9, and the third photoelectric sensor 9 is provided with three groups, each group of the third photoelectric sensors 9 includes a pair of third photoelectric sensors 9 respectively provided on both sides of the lifting plate, and the level of the group of third photoelectric sensors 9 located in the middle of the three groups of third photoelectric sensors 9 is higher than that of the other two groups of third photoelectric sensors 9, and the upper surface of the product horizontally placed on the positioning fixture 1 is taken as the reference surface, when the positioning fixture 1 is transported to the conveyor belt 8, the level of the middle group of third photoelectric sensors 9 is set higher than the upper surface of the product carried on the positioning fixture 1, and the levels of the other two groups of third photoelectric sensors 9 are consistent and when the positioning fixture 1 is transported to the conveyor belt 8, the levels of the other two groups of third photoelectric sensors 9 are between the level of the upper surface of the product and the level of the lower surface. When taking the reference surface, whether the product is horizontally carried on the positioning fixture 1 can be detected by a level meter, so as to determine the setting position of the third photoelectric sensor 9.
[0048] When the first photoelectric sensor 10 detects that the positioning fixture 1 is transported to the designated position by the conveyor belt 8, the three groups of third photoelectric sensors 9 are used to detect whether the product carried on the positioning fixture 1 is placed horizontally. When the product is carried horizontally on the positioning fixture 1, the photoelectric signals transmitted to each other by the middle group of third photoelectric sensors 9 are not blocked by the product, and the photoelectric signals transmitted to each other by the other two groups of third photoelectric sensors 9 are blocked by the sides of the product. Whether the product is horizontal can be determined based on the detection state of the three groups of third photoelectric sensors 9. Since the photoelectric signals transmitted to each other by the middle group of third photoelectric sensors 9 are not blocked by the product, and the photoelectric signals transmitted to each other by the other two groups of third photoelectric sensors 9 are blocked by the sides of the product, the product will also be in a non-horizontal state. Due to the limited thickness of the product and the limited height difference between the middle group of third photoelectric sensors 9 and the other two groups of third photoelectric sensors 9, the error generated can be ignored.
[0049] To sum up, the embodiments provided by the utility model can not only improve the transportation stability and accuracy of products transported in a lifting state, but also determine whether the placement state of the product on the positioning tooling 1 is horizontal, and has high practical value in the application of multi-layer product conveyor lines.
[0050] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
