Abstract
Description
Technical Field
[0001] This utility model relates to the field of transportation devices, and in particular to an automatic detection and shutdown device for stacking small box machines. Background Technology
[0002] Some bagged products are pre-packaged in boxes before being sold. The packaging process generally involves placing the bagged products on a conveyor belt, which then transports them to the next workstation, where they are finally packaged into boxes.
[0003] Specifically, the conveyor belt is equipped with baffles that divide the space above the conveyor belt into multiple chambers. Bagged products are placed in these chambers, with a specified quantity in each chamber. For ease of understanding, we will use the example of one bag per chamber for further explanation. When the conveyor belt transports products to subsequent workstations, it is easy for two bags to be placed in a single chamber. During the subsequent packaging process, because the two bags cannot be packed into the box simultaneously, they become stuck in the equipment and difficult to remove, causing equipment downtime or even damage. Utility Model Content
[0004] To address the problem of equipment downtime caused by the difficulty in detecting extra products placed in the conveyor belt chamber, this invention provides an automatic detection and shutdown device for stacked packaging in small box machines.
[0005] This utility model provides an automatic detection and shutdown device for stacking packaging machines for small boxes, which adopts the following technical solution:
[0006] An automatic detection and shutdown device for stacking small boxes includes a base, a proximity switch on the base, and a telescopic rod on the base, one end of which extends into the detection range of the proximity switch.
[0007] In one specific implementation, a stop is provided at the end of the telescopic rod away from the base, and an elastic element is provided between the stop and the base.
[0008] In one specific implementation, the elastic element is a spring.
[0009] In one specific implementation, a slot is provided on the side wall of the base, and a locking bolt is provided on the base, with one end of the locking bolt extending into the slot.
[0010] In one specific implementation, a lifting rod for fixing the base is also included.
[0011] In one specific implementation, the proximity switch is threadedly connected to the base.
[0012] In summary, this utility model has the following beneficial effects:
[0013] When too many products are placed on the equipment, the telescopic rod will be raised, causing the proximity switch to activate and stop the equipment. After the excess products are removed, the equipment will resume operation, thus alleviating the problem of equipment downtime caused by excessive product placement and improving equipment production efficiency.

[0017] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.
[0018] Reference Figure 1 and Figure 2 The automatic detection and shutdown device for the small box stacking machine includes a base 1, with a slot 6 on its side wall. The base 1 is engaged with the lifting rod (not shown in the figure) of the production equipment via the slot 6, and moves up and down above the conveyor belt with the lifting rod. A locking bolt 7 is threaded onto the base 1, with the bottom end of the locking bolt 7 extending into the slot 6. By rotating the locking bolt 7, the stability of the connection between the base 1 and the lifting rod can be improved through the locking action of the locking bolt 7.
[0019] Reference Figure 1 A proximity switch 2 is threadedly connected to the top of the base 1. The detection end of the proximity switch 2 is inside the base 1. A telescopic rod 3 is provided at the bottom of the base 1. The top end of the telescopic rod 3 extends into the base 1, and the end of the telescopic rod 3 inside the base 1 can be detected by the proximity switch 2. A stop block 4 is fixedly connected to the bottom end of the telescopic rod 3.
[0020] Under normal conditions, during the lifting and lowering process of the lifting rod, the base 1 and the stop block 4 rise and fall together. Since the number of products on the conveyor belt is the same as the required number, the stop block 4 does not directly contact the products, or even after the stop block 4 contacts the products, the telescopic rod 3 remains stable and does not trigger the proximity switch 2. At this time, the conveyor belt carries the products normally. When there are too many products on the conveyor belt, during the descent of the stop block 4, the products block the stop block 4 from falling, preventing it from descending to the normal height. At this time, the telescopic rod 3 retracts into the base 1 and triggers the proximity switch 2, causing the proximity switch 2 to send a stop signal to the main unit of the conveyor belt. When the workers remove the products under the stop block 4, the stop block 4 falls, the telescopic rod 3 no longer triggers the proximity switch 2, and the conveyor belt resumes operation.
[0021] Reference Figure 1 and Figure 2 A spring 5 is installed between the stop block 4 and the base 1. The spring 5 is sleeved on the telescopic rod 3, with one end connected to the base 1 and the other end connected to the stop block 4. When the stop block 4 is lifted by a product, the spring 5 is compressed. When additional products are removed, the elastic force of the spring 5 causes the stop block 4 and the telescopic rod 3 to automatically return to their original positions. Simultaneously, the spring 5 provides elasticity, making it difficult for the stop block 4 to be lifted. When products are placed on the conveyor belt, due to air inside the packaging bags and the inability to ensure the packaging bags are in a uniform state during placement, the products are prone to tilting. In this case, the product height differs from the ideal product height, which may cause the tilted product to block the stop block 4 from falling, leading to misjudgment. The elastic force of the spring 5 ensures that when the stop block 4 falls, the pressure will push the tilted product back to its normal position, thus avoiding misjudgment.
[0022] The implementation principle of this utility model embodiment is as follows: During the lifting and lowering process of the lifting rod, the base 1 and the stop 4 are lifted and lowered together. Under normal conditions, during the descent of the stop 4, the stop 4 falls normally, and the telescopic rod 3 remains stable. When there are additional products in the chamber on the conveyor belt, the products block the normal descent of the stop 4, the telescopic rod 3 retracts into the base 1, triggering the proximity switch 2. The proximity switch 2 sends a signal to the main unit of the conveyor belt, and the conveyor belt stops conveying. After the additional products are removed, the conveyor belt resumes operation.
[0023] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
