[0023] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings as follows:

[0024] The utility model proposes a tablet transport device, referring to Figure 1 As shown, it mainly comprises: a feeding unit 1, a transport unit 2 and a discharging pipe 3. The feeding units 1 are arranged in a plurality and each feeding unit 1 comprises a feeding plate 13, a feeding pipe 11 and a pusher 121. The feeding plate 13 is arranged horizontally, and the feeding pipe 11 is vertically arranged at the outer end of the feeding plate 13. A feeding port is provided at the top of the feeding pipe 11, and the bottom of the feeding pipe 11 is fixedly connected to the outer end of the feeding plate 13. After tabletting and surface treatment, the tablets enter the feeding pipe 11 through the feeding port. Due to the size limitation of the feeding pipe 11, the tablets are arranged in the feeding pipe 11 in the vertical direction of the feeding pipe 11 in sequence. The plurality of feeding units work synchronously to ensure the feeding efficiency. A correction unit (not shown in the figure) is arranged at the top of the feeding pipe 11 to allow the tablets to enter the feeding pipe 11 in a horizontal state. The arrangement here belongs to the conventional prior art and does not belong to one of the technical features to be solved by the present invention, so the present invention will not elaborate on it.

[0025] The bottom end of the feed pipe 11 is provided with a connecting port in the same direction along the length direction of the feed plate 13, and the height of the connecting port is equal to the thickness of the tablet. The feed cylinder 12 faces the connecting port and is arranged outside one end of the feed plate 13. The piston rod of the feed cylinder 12 is fixedly connected to the push handle 121. The push handle 121 includes a connector and two push plates. The connector is fixedly connected to the piston rod. The push plates are arc-shaped. The two push plates are symmetrically arranged on both sides of the connector and fixedly connected to the connector, so that the push plates match the outer contour of the tablet. The inner wall of the connector and the push plate is provided with a first buffer layer (not shown in the figure). The first buffer layer has a buffering effect on the tablet to prevent the push handle 121 from damaging the tablet due to collision with the tablet during movement.

[0026] In one embodiment, the number of feed cylinders corresponds to the number of pushers, and each pusher is fixedly connected to the end of the piston rod of a feed cylinder, so that each feed cylinder drives a pusher to slide reciprocatingly; in another embodiment, there is one feed cylinder, and multiple pushers are fixedly connected to the end of the piston rod of the feed cylinder through a connecting plate, and the pushers and the connecting plate are connected by a connecting rod, so that one feed cylinder drives multiple pushers to slide reciprocatingly synchronously, and the pushers and the connecting rod pass through the connecting port.

[0027] The piston rod of the feed cylinder 12 drives the push handle 121 to slide, and the push handle 121 extends into the connecting port, pushing the tablets at the bottom of the feed pipe 11 to slide along the feed plate 13 toward the conveying unit. Since the piston rod of the feed cylinder 12 is inserted into the connecting port, other tablets in the feed pipe 11 will not fall down until the piston rod of the feed cylinder 12 contracts, and the tablets in the feed pipe 11 automatically fall down under the action of gravity, and the cycle repeats, so that the tablets in the feed pipe continue to fall to the connecting port. The height of the piston rod of the feed cylinder 12 is the same as the top height of the push handle 121, so as to prevent the tablets from falling prematurely.

[0028] The transport unit 2 includes a conveyor belt 23, a transport roller 21 and a transport motor 22. There are two transport rollers 21. The two ends of the conveyor belt 23 are mounted between the two transport rollers 21 through the transport rollers 21 and are respectively slidably connected with the corresponding transport rollers 21. The conveyor belt 23 performs transmission movement from the head end to the discharge end, and the discharge pipe 3 is arranged at the discharge end of the conveyor belt 23. One side of the conveyor belt 23 in the length direction is close to one end of the feed cylinder 12 of the feed plate 13, and the plane where the top surface of the conveyor belt 23 is located is lower than the plane where the top surface of the feed plate 13 is located. The feed cylinder 12 pushes the tablets to the inner end of the feed plate 13 through the feed plate 13, and due to the height difference of the plane, the tablets fall onto the conveyor belt 23 under the action of gravity.

[0029] A baffle 4 is provided on the side of the conveyor belt 23 away from the feed plate 13. The baffle 4 is arc-shaped, and the bottom end of the baffle 4 faces the conveyor belt 23. A second buffer layer (not shown in the figure) is fixedly provided on the side of the baffle 4 facing the conveyor belt 23. The setting of the arc-shaped baffle 4 can effectively prevent the tablets from being separated from the conveyor belt 23 due to excessive thrust of the cylinder. If the tablets are separated from the conveyor belt 23, they will slide upward along the arc surface of the baffle 4 to buffer the impact, and finally slide naturally on the surface of the conveyor belt 23 under the action of gravity. For some tablets that are pushed out too quickly and hit the baffle 4, the second buffer layer can also provide buffering protection for the tablets in this case to avoid damage to the tablets.

[0030] The materials of the first buffer layer and the second buffer layer are soft materials such as silicone, rubber, etc., and this application does not impose any specific limitation thereto.

[0031] The transport roller 21 includes a driving roller and a driven roller, and the conveying shaft of the transport motor 22 is fixedly connected to the axis of the driving roller. In this embodiment, the driving roller is the transport roller 21 at the head end of the conveyor belt 23. The transport motor 22 can be a stepping motor, which can make the conveyor belt 23 move and transmit in a certain regular manner through stepping rotation, so as to avoid excessive concentration of tablets falling into the discharge pipe 3 and causing accumulation and blockage.

[0032] After pushing the tablet, the feeding cylinder 12 needs to retract, and then push the next tablet into the conveyor belt 23. Therefore, there will inevitably be a certain time difference when the tablet enters the conveyor belt 23. The stepping motion mode can adapt to the time difference, improve the use efficiency of the conveyor belt 23, and avoid the waste of power resources. At the same time, the non-stepping operation mode will give the conveyor belt 23 a certain inertia. When the tablet falls off the conveyor belt 23, the inertia may cause the tablet to be difficult to stabilize during the falling process.

[0033] The discharge pipe 3 is funnel-shaped, a packaging body is arranged below the discharge pipe 3, and a counting sensor (not shown in the figure) is arranged at the bottom of the discharge pipe 3. The tablets falling one by one are more convenient for the counting sensor to perform accurate counting, thereby further avoiding errors.

[0034] The working process of the utility model is:

[0035] Multiple tablets are stacked through the feed tube 11, and the tablets at the bottom layer slide from the feed plate 13 into the conveyor belt 23 under the push of the pusher 121, and enter the discharge tube 3 driven by the conveyor belt 23, and finally enter the packaging body. The pusher 121 pushes the tablets into the conveyor belt 23 and then retracts. The tablets in the feed tube 11 continue to fall under the action of gravity, and the above actions are repeated.

[0036] In order to prevent the tablets from falling off during transportation, guardrails (not shown in the figure) are provided on both sides of the feed plate 13 corresponding to the positions of the conveyor belt 23. The design here is a conventional design and will not be described in detail.

[0037] As for other undisclosed technologies of the present invention, such as the power transmission mode and the working principle of the counting sensor, the prior art is mature and does not belong to the technical problems mainly solved by the present invention, the present invention will not elaborate or limit them.

[0038] The above detailed description is a specific description of a feasible embodiment of the present invention, but the embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not deviate from the technical spirit of the present invention should be included in the patent scope of this application.
