Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically to a grid conveying device for a packaging machine. Background Technology

[0002] A blister packing machine typically consists of a blister packaging machine and a blister packing machine. The blister packaging machine forms, seals, and cuts the blister packs, while the packing machine packs the blister packs into boxes. After the blister packs are sealed and cut, they are conveyed to the front via a grid conveyor. Then, a robotic arm transfers the blister packs from the grid conveyor to the feeding conveyor of the blister packing machine. The blister packs are then pushed into the cartons on the feeding conveyor of the blister packing machine, thus completing the packing process. For example, the invention patent CN109436436B disclosed by the applicant provides an isolated partition grid conveyor system. The disclosed grid conveyor has three conveying channels, each consisting of a grid conveyor chain hook (i.e., a grid conveyor belt), a drive sprocket, and a driven sprocket. The grid conveyor chain hook is wound around the drive sprocket and the driven sprocket, and the drive sprocket is connected to a power source. Driven by the power source, the grid conveyor chain hook rotates, thereby conveying the blister packs. From the appendix of this patent... Figure 6 As can be seen, each channel is independent, and each channel is equipped with two grid conveyor chain hooks. Each grid conveyor chain hook is equipped with a pusher plate (the pusher plate is used to push the blister pack forward). Since each channel has at least one partition on its side, the pusher plate on each grid conveyor chain hook is independent. This makes the structure of the entire grid conveying device very complex, requiring a large number of grid conveyor chain hooks, drive sprockets, and driven sprockets. This results in high costs. Moreover, the two grid conveyor chain hooks in each channel must be adjusted to the same position so that the pusher plates on the two grid conveyor chain hooks are level from left to right. At the same time, it is also necessary to ensure that all the pusher plates on the six grid conveyor chain hooks in the three channels are level from left to right, which is very inconvenient for adjustment. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a grid conveying device with lower cost and more reasonable structure.

[0004] This grid conveying device includes a mounting base, a drive belt, a pulley, and several conveying grid strips. The drive belt is wound around the pulley. The device is characterized in that: the drive belt has two sides, left and right, and the two ends of the conveying grid strips are respectively connected to the two drive belts. Several conveying grid strips are equally connected to the drive belts. A support platform is provided between the two drive belts, and the conveying grid strips push the material above the support platform.

[0005] The surface of the support platform is provided with a groove extending along the conveying direction, and the bottom of the conveying grid has a protrusion, which extends downward into the groove of the support platform.

[0006] The surface of the support platform is provided with multiple grooves, and the distance between two adjacent grooves is less than the length of the blister pack; the bottom of the conveying grid has multiple protrusions, each protrusion corresponding to a groove.

[0007] The two ends of the conveyor grid are connected to support wheels, and the mounting base is provided with a lower support surface. The lower support surface is located below the transmission belt, and the support wheels located below act on the lower support surface.

[0008] The mounting base is provided with an upper support surface, which is located on the outside of the transmission belt, and the support wheel located above acts on the upper support surface.

[0009] The grid conveying device provided by this utility model greatly simplifies the structure of the grid conveying and reduces the manufacturing cost by using a transmission belt, pulleys and several conveying grid bars. Attached Figure Description

[0015] Figure 6 for Figure 4 A magnified view of a section at point B. Detailed Implementation

[0016] like Figure 1 and Figure 2 As shown, this grid conveying device includes a mounting base 1, a drive belt 2, a pulley 4, and several conveying grid bars 3. The drive belt 2 is wound around the pulley 4 (it can also be replaced by a chain and sprocket, which is an equivalent technology). The pulley 4 is driven to rotate by a power source, and the pulley 4 moves the drive belt 2 in a cyclical motion.

[0017] like Figure 2As shown, the transmission belt 2 has two belts, left and right. The two ends of the conveyor strip 3 are connected to the left and right transmission belts 2 respectively (the left end of the conveyor strip 3 is connected to the left transmission belt 2, and the right end of the conveyor strip 3 is connected to the right transmission belt 2). Several conveyor strips 3 are evenly connected to the transmission belt 2. The spacing between two adjacent conveyor strips 3 forms the space for placing the bubble sheet. A support platform 5 is provided between the two transmission belts 2. The conveyor strip 3 pushes the material above the support platform 5.

[0018] During operation, the power source drives the pulley 4 to rotate, which in turn drives the transmission belt 2 forward in a cyclical motion. Since the two ends of the conveyor strip 3 are connected to the left and right transmission belts 2, the conveyor strip 3 moves forward together, also in a cyclical motion. The robotic arm picks up the blister pack and places it on the support platform 5, positioned between two adjacent conveyor strips 3. As the conveyor strip 3 moves forward, it pushes the blister pack P forward. This structure eliminates the partitions between multiple channels, replacing the existing multi-channel, multi-push-plate structure with a single conveyor strip 3, significantly reducing manufacturing difficulty and cost. Furthermore, it eliminates the need for any alignment adjustments, significantly reducing the difficulty of equipment installation and debugging.

[0019] Since the conveyor grid 3 pushes the material above the support platform 5, there will inevitably be a gap between the conveyor grid 3 and the support platform 5. If the blister pack P is twisted or deformed or too thin, the surface of the blister pack P may get stuck in the gap between the conveyor grid 3 and the support platform 5, preventing the subsequent blister packs from being picked up by the robot. To solve this problem, such as... Figure 2 As shown, a groove 50 extending along the conveying direction is provided on the surface of the support platform 5, such as... Figure 3 As shown, the bottom of the conveyor grid 3 has a protrusion 31, such as... Figure 4 and Figure 5 As shown, the protrusion 31 of the conveyor strip 3 extends downward into the groove 50 of the support platform 5. In this way, the lower end of the protrusion 31 of the conveyor strip 3 is lower than the surface of the support platform 5. The surface of the blister pack will be stuck outside by the protrusion 31 of the conveyor strip 3 and cannot enter between the conveyor strip 3 and the support platform 5, thereby ensuring that the blister pack can be picked up by the robot in the subsequent process.

[0020] If multiple rows of bubble wrap are conveyed at one time (e.g.) Figure 2If three rows are conveyed at once, then multiple grooves 50 are provided on the surface of the support platform 5. The distance between two adjacent grooves 50 is less than the length of the blister pack (multiple rows of blister packs are generally arranged in the length direction; if they are arranged in the width direction, then the distance should be less than the width of the blister pack). The bottom of the conveying grid 3 has multiple protrusions 31, each protrusion 31 corresponding to a groove 50. In this way, it is impossible for all blister packs to get stuck between the conveying grid 3 and the support platform 5.

[0021] Because the drive belt 2 is relatively long, in order to prevent the drive belt 2 from sagging, such as Figure 4 and Figure 6 As shown, support wheels 30 are connected to both ends of the conveyor grid 3, and a lower support surface 11 is provided on the mounting base 1. The lower support surface 11 is located below the transmission belt 2. The support wheels 30 located below act on the lower support surface 11, that is, the support wheels 30 on the lower section of the transmission belt 2 act on the lower support surface 11. The lower support surface 11 provides support for the support wheels 30, and the support wheels 30 are connected to the transmission belt 2 through the conveyor grid 3. This can prevent the lower section of the transmission belt 2 from sagging downwards and ensure the stability and running accuracy of the transmission belt 2.

[0022] Similarly, an upper support surface 10 is provided on the mounting base 1. The upper support surface 10 is located on the outside of the transmission belt 2. The upper support wheel 30 acts on the upper support surface 10. That is, the support wheel 30 on the upper section of the transmission belt 2 acts on the upper support surface 10. The upper support surface 10 provides support for the support wheel 30. The support wheel 30 is connected to the transmission belt 2 through the conveyor grid 3. This can prevent the upper section of the transmission belt 2 from sagging downward and ensure the stability and running accuracy of the transmission belt 2.
