Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

The specification specifies that the transportation direction of the whole turnover conveyor belt in fig. 1 is the left-right direction, the extending direction of the transposition track 1 is the front-back direction, fig. 1 shows a turnover conveyor device of the utility model, which comprises a left transposition track 1 and a right transposition track 1 extending along the front-back direction, and a turnover seat 2 capable of moving and turning over along the transposition track 1, wherein the turnover seat 2 comprises a main roller 24 matched with the transposition track 1, and a first turnover frame 21 and a second turnover frame 22 which are mutually L-shaped; the lower end of the second roll-over stand 22 is fixedly connected with the front end or the rear end of the first roll-over stand 21 to form a corner unit 23, the left side and the right side of the corner unit 23 are rotatably connected with main rollers 24, and two positioning stoppers 11 which are opposite in the front-back direction and used for limiting the main rollers 24 in the front-back direction are arranged on the transposition track 1. The left main roller 24 runs in the left transposition track 1, the right main roller 24 runs in the right transposition track 1, and the main roller 24 is limited by the positioning stoppers 11 in the front-back direction, so that the main roller 24 can only move in the region between the front positioning stopper 11 and the rear positioning stopper 11 in the transposition track 1, and the overturning seat 2 can overturn by taking the main roller 24 as a fulcrum. This upset conveyor needs first roll-over stand 21 or second roll-over stand 22 to be the tiling form when using, and main gyro wheel 24 is located the common tip of first roll-over stand 21 and second roll-over stand 22, so if only rely on main gyro wheel 24 to set up on transposition track 1, first roll-over stand 21 and second roll-over stand 22 can't be the tiling form and put up on transposition track 1, consequently rotate on first roll-over stand 21 and be connected with can with transposition track 1 complex first auxiliary roller 25, rotate on the second roll-over stand 22 and be connected with can with transposition track 1 complex second auxiliary roller 26, the quantity of first auxiliary roller 25 and second auxiliary roller 26 all has at least one.

When the turnover conveying device is used, the first conveying belt a for conveying materials in the left-right direction is fixed on the first turnover frame 21, and the second conveying belt b for conveying materials in the left-right direction is fixed on the second turnover frame 22, so that the positions of the first conveying belt a and the second conveying belt b in the front-back direction are determined by the positions of the first turnover frame 21 and the second turnover frame 22 when the first turnover frame 21 and the second turnover frame 22 are in a flat state, the L-shaped turnover seat 2 needs to be turned over to enable the first turnover frame 21 or the second turnover frame 22 to be in a flat state, the flat positions of the first turnover frame 21 and the second turnover frame 22 need to be determined according to actual conditions, and the positions of the first turnover frame 21 and the second turnover frame 22 are determined by determining the positions of the positioning stop blocks 11. When needs overturn, earlier with upset seat 2 forward or backward promote to main gyro wheel 24 and a location dog 11 and lean on and withstand, then use main gyro wheel 24 to overturn as the fulcrum upset seat 2, location dog 11 supports main gyro wheel 24 all the time in order to avoid its aversion at the upset in-process to the realization is to the switching of first roll-over stand 21 and second roll-over stand 22. Because the turnover conveying device is mainly used in the middle of the linear conveying belt, when the first turnover frame 21 is in a flat state, the first conveying belt a needs to be aligned with the linear conveying belt, when the second turnover frame 22 is in a flat state, the second conveying belt b needs to be aligned with the linear conveying belt, i.e. whether the first and second roll-over stands 21, 22 are in a flat position, they are required to be in a certain position in the middle of the linear conveyor belt, therefore, in the embodiment, the positions of the two positioning stoppers 11 are determined after calculation, so that the rotation center of the turnover seat 2 is determined, and it is ensured that the first turnover frame 21 or the second turnover frame 22 which is changed from the vertical state to the flat state just falls into the position determined in the middle of the linear conveyor belt after each turnover, therefore, the turnover seat 2 does not need to be moved and adjusted after turnover, and turnover efficiency is improved. During the turning, the main roller 24 is a fulcrum and is always located on the transposition track 1, and the first auxiliary roller 25 and the second auxiliary roller 26 need to go in and out of the transposition track 1 along the up-and-down direction, so that the groove opening on the transposition track 1 for matching with the first auxiliary roller 25 and the second auxiliary roller 26 is preferably upward. In the present embodiment, the first auxiliary roller 25 or the second auxiliary roller 26 also travels on the shift rail 1, but the positioning block 11 is required to block only the main roller 24 and not the first auxiliary roller 25 and the second auxiliary roller 26, so it is preferable that the first auxiliary roller 25 and the second auxiliary roller 26 have a size smaller than that of the main roller 24 and are not blocked by the positioning block 11 during traveling.

The movement of the turnover seat 2 depends on the matching of the main roller 24 and the transposition track 1, the turnover of the turnover seat 2 depends on the abutting of the main roller 24 and the transposition track 1 and the positioning stop block 11, a track pressing plate 12 is preferably fixed above the transposition track 1 in the embodiment, the lower surface of the track pressing plate 12 abuts against the main roller 24, the stability of the main roller 24 is improved by fully limiting the main roller 24 in the transposition track 1, and therefore the stability of the movement and turnover of the turnover seat 2 is improved. Meanwhile, in order to meet the requirement that the first auxiliary roller 25 and the second auxiliary roller 26 can enter and exit the transposition track 1 when turning along with the turning seat 2, a notch for the first auxiliary roller and the second auxiliary roller to enter and exit needs to be formed in the track pressing plate 12. Since the turning position of the turning seat 2 is determined, the opening position of the gap on the track can be determined according to the installation positions of the first secondary roller 25 and the second secondary roller 26 on the turning seat 2, as shown in fig. 5, according to the turning position of the turning seat 2 in the present embodiment, the first half of the track pressing plate 12 is separately provided with a first positioning inlet 121 for the first secondary roller 25 to enter the transposition track 1 and a first positioning outlet 122 for the first secondary roller 25 to leave the transposition track 1, and the second half of the track pressing plate 12 is provided with a second positioning inlet 123 for the second secondary roller 26 to enter the transposition track 1 and a second positioning outlet 124 for the second secondary roller 26 to leave the transposition track 1. Since the positions of the positioning inlet and the positioning outlet are determined according to the specific size calculation on site, only when the turnover seat 2 moves until the main roller 24 completely abuts against the positioning stop 11 and is turned over, it can be ensured that the first auxiliary roller 25 can correspondingly enter the first positioning inlet 121 or correspondingly leave the first positioning outlet 122, and the second auxiliary roller 26 is the same. The advantage of design like this has been in having guaranteed the position precision of upset, in case main gyro wheel 24 does not lean on totally to hold the position dog 11, just can't overturn upset seat 2, avoids appearing the inaccurate condition in position after the upset.

Before the turning seat 2 is turned, the main roller 24 moves to a position abutting against the positioning stop block 11 on the transposition track 1; firstly, the main roller 24 collides with the positioning stop block 11 after moving for a certain distance, and generally, in order to ensure the overturning efficiency in an actual field, the speed of a worker pushing the overturning seat 2 is higher, so that the interaction force is larger when the main roller 24 collides with the positioning stop block 11; when the overturning seat 2 overturns with the main roller 24 as a fulcrum, the interaction force between the main roller 24 and the positioning stop 11 is also larger; the main roller 24 is limited in the area between the two front and rear opposite positioning blocks 11 on the transposition track 1, so that the preferred positioning block 11 of the embodiment has an arc surface 112 facing to another positioning block 11 along the front and rear direction and matching with the wheel surface of the main roller 24, the arc surface 112 matches with the wheel surface of the main roller 24 in shape and has a larger contact surface, so that the main roller 24 can be prevented from being damaged when the positioning block 11 blocks the main roller 24 through the arc surface 112, the stability of the main roller 24 abutting against the positioning block 11 is improved, and meanwhile, the wrapping performance of the arc surface 112 on the wheel surface of the main roller 24 is better, so that the main roller 24 collides with the positioning block 11 smoothly, and the generation of noise is reduced.

The overturning seat 2 mainly plays a role in mounting the first conveying belt a and the second conveying belt b, moving along the transposition track 1 and overturning, the structure of the overturning seat is not necessarily too complex, and the overturning seat is reduced as much as possible on the premise of ensuring the supporting strength so as to play a role in reducing weight, thereby facilitating the overturning of the overturning seat 2. Fig. 7 shows that in the present embodiment, preferably, the first roll-over stand 21 is composed of a first left guide plate 211 and a first right guide plate 212 which are parallel to each other, and the second roll-over stand 22 is composed of a second left guide plate 221 and a second right guide plate 222 which are parallel to each other, so that the weight reduction of the roll-over stand 2 is realized on the premise of ensuring the supporting strength; the first left guide plate 211 is fixedly connected with the second left guide plate 221 and forms a left corner portion 231, the first right guide plate 212 is fixedly connected with the second right guide plate 222 and forms a right corner portion 232, and the left corner portion 231 and the right corner portion 232 constitute the corner unit 23.

The main roller 24, the first auxiliary roller 25 and the second auxiliary roller 26 guide the turnover seat 2 to move along the transposition track 1 and support the turnover seat 2, and when the first conveying belt a and the second conveying belt b on the turnover seat 2 convey goods, the main roller 24, the first auxiliary roller 25 and the second auxiliary roller 26 and the connection part between the main roller 24, the first auxiliary roller 25 and the second auxiliary roller 26 and the turnover seat 2 need to bear larger pressure; at the moment, the resistance of the three rollers to advance on the transposition track 1 is large, the moving speed of the turnover seat 2 on the transposition track 1 is seriously influenced, and the overall efficiency of turnover conveying is never influenced; in addition, be connected for rotating between three gyro wheel and the upset seat 2, its main effect of rotating the connecting portion is to guarantee to rotate, is difficult to guarantee the intensity that self is used for the support simultaneously structurally.

The roll-over stand 2 moves along the left support rail 3 and the right support rail 4 through the first roll-over stand 21 or the second roll-over stand 22, and the convex parts on the left corner 231 and the right corner 232 extend downward when the roll-over stand is turned over, so that the left support rail 3 is provided with a left avoidance notch 31 for avoiding the left corner 231 in the embodiment, and the right support rail 4 is provided with a right avoidance notch 41 for avoiding the right corner 232. In the reversed position, the main roller 24 corresponds to the positioning stopper 11, and the main roller 24 is rotatably connected to the left and right sides of the corner unit 23, so that the corner unit 23 also corresponds to the positioning stopper 11 in the left-right direction, so that the left escape notch 31 is provided at two positions on the left support rail 3 corresponding to the positioning stopper 11, and the right escape notch 41 is provided at two positions on the right support rail 4 corresponding to the positioning stopper 11. The existence of the left avoidance notch 31 and the right avoidance notch 41 ensures the smoothness of the turnover seat 2, and simultaneously further improves the turnover precision of the turnover seat 2, because the turnover seat 2 cannot be smoothly turned if the left corner 231 does not reach the left avoidance notch 31 or the right corner 232 does not reach the right avoidance notch 41.
