Detailed Description
The invention will now be further illustrated by reference to the following examples, which are intended to be illustrative, not limiting, and are not intended to limit the scope of the invention.
As shown in fig. 7, 8, 9 and 10, the elevator 5 comprises a bottom plate 24 and side plates 22, two ends of the bottom plate are respectively provided with one side plate, lifting action is completed by a belt 17, and the side walls 3 arranged on two sides of the vending machine box 1 are close to the box opening 6, so that the invention has the innovation that: the two belts are provided with follower plates 21 through fixing pieces 12, and the inner side of each follower plate is limited and clamps one side plate on the same side.
In this embodiment, a bending edge 43 is disposed at the lower end of the inner surface of the follower plate, the bending edge contacts with the bottom surface of the side plate, at least one limiting edge is disposed on the inner side of the follower plate, the limiting edge limits the outer side of the side plate, and a clamping plate 35 is disposed at the upper end of the follower plate, and contacts with the inner surface of the side plate. The functions of each structure are as follows: the limiting edges limit the movement of the side plates in the front-back direction, and the clamping plates and the bending edges are matched with the movement of the limiting side plates in the up-down direction.
The specific structure of the clamping plate is as follows: the upper end 38 of the clamping plate is connected with the upper end of the follow-up plate through bolts 36, and the lower end of the clamping plate extrudes the side plate on the inner side surface of the follow-up plate. The upper end bottom of the clamping plate is integrally provided with a pressing section 40 which presses the upper end face of the side plate, the inner side of the pressing section is integrally provided with a pressing section 39 which inclines towards the direction of the follow-up plate, and the pressing section presses the inner side surface of the side plate and presses the side plate on the follow-up plate.
The rear end edge of the follower plate is integrally provided with a limiting edge 37 which is pressed on the rear end face of the side plate, the front end of the follower plate is integrally provided with another limiting edge 42 which is pressed on the front end face of a clamping edge 41 which is oppositely arranged on the side plate.
The front end of the follower plate is provided with a mounting section 54 in the opposite direction to the other limit edge, which is driven by the belt via a fixing element.
The structural relationship between the follower plate and the side plate is:
at the time of installation
The elevator is placed at the position above the two follow-up plates, so that the two side plates at the two sides of the elevator slide downwards along the limit edges from the upper direction, when the elevator slides downwards to the bottom surface of the side plate to press the bending edges, the clamping plate is pressed on the side plate, and then the upper end of the clamping plate and the upper end of the follow-up plate are fixed by bolts, so that the installation of the elevator is completed.
Upon disassembly
And (3) detaching the bolts, taking off the clamping plates, moving the whole elevator upwards, and finally sliding out from the follow-up plate to finish the disassembly of the elevator.

The specific structure of a weighing sensor is as follows: the front and rear ends of the base plate are laterally provided with projecting ribs 33 and 28, respectively, and the weighing sensor is mounted on both projecting ribs and is located approximately in the middle of the base plate in the lateral direction. The preferable scheme is as follows: a mounting plate 31 is inserted in the space 29 between the two projecting edges, and the front end 34 and the rear end 30 of the mounting plate are fixed to the projecting edges of the front end and the projecting edges of the rear end of the base plate, respectively.
The panel is shown in fig. 6 to be of a structure gradually inclined downwards from back to front, and the front end of the panel is obliquely upwards provided with an integral extension section 27, and the front end of the extension section is provided with an integral bending section 26. The mounting panel up end with weighing sensor's bottom surface is connected, and the two can be fixed each other through modes such as bolt, sticky, in this example, is provided with the bolt hole with fixed panel's bolt 25 matched with at weighing sensor's weighing end. The mounting plate adopts the shape that is approximately the same with the slope shape of panel, guarantees weighing sensor's installation stability and the connection convenience with the panel from this.
In addition to the gaps on the bottom surface of the panel, gaps are reserved between the end surfaces on two sides of the panel and the surfaces of the side plates.
When weighing, firstly, the elevator vertically moves to a proper warehouse position, the goods are pushed onto the panel and move towards the extension section, at the moment, the weighing sensor detects weight increase, then the weight increase is compared with a preset weight value in the control system, if the weight value falls into a correct range, the goods which are indicated to be correct fall onto the panel, and the elevator returns to the goods taking opening for people to take out the goods. If abnormal weight increase is detected, an error processing stage is entered, or on-site alarm information is given, or prompt information is given on a display screen, or remote alarm information is given.
Of course, some applications require the use of more load cells, the specific number of which is determined by the requirements, such as: extending the two sides of the mounting plate, and respectively arranging a weighing sensor on the left side and the right side of the upper end surface of the mounting plate; for another example: three weighing sensors are respectively arranged on the left side, the middle part and the right side of the upper end face of the mounting plate. No matter how many weighing sensors are arranged, the weighing ends of the weighing sensors are connected with the bottom surface of the panel, and certain gaps are reserved on two sides of the panel, the front end and the rear end.
