[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0032] like Figures 1 to 8The embodiment of the present invention preferably provides a non-stop workstation unloading device, including a base 1, and a conveyor belt 2 arranged on the base 1, on which a plurality of mobile hoppers 3 for evenly placing materials are arranged; a feeding structure 4 for delivering materials to the mobile hopper 3 is arranged at the front section of the conveyor belt 2; a blanking structure 5 for intermittently unloading multiple materials is arranged at the rear section of the conveyor belt 2; a pushing structure 6 for pushing the materials in the mobile hopper 3 to the blanking structure 5 is arranged above the conveyor belt 2, and a return structure 7 for preventing the pushing structure 6 from interfering with the mobile hopper 3 when returning; a limiting structure 8 for facilitating the pushing of small-volume soft materials to avoid their sticking is arranged on the pushing structure 6, the return structure 7 and the mobile hopper 3; and a control panel 9 is also arranged on the base 1. The material in this technical solution is a medicine spoon, which finally falls into the medicine package through the unloading device in this technical solution. The conveyor belt is fixed on the base, and the working mode is intermittent start. The mobile hopper is arranged on the conveyor belt. The feeding structure is arranged at the transmission starting end of the conveyor belt, and is used to send the medicine spoon into the mobile hopper of the conveyor belt. The blanking structure is arranged on one side of the transmission end of the conveyor belt. When the number of medicine spoons loaded in the mobile hopper on the conveyor belt is sufficient, the medicine spoon is pushed by the pushing structure to leave this equipment and enter the subsequent drug packaging transmission equipment. After pushing, the pushing structure returns to its original position through the return structure, and can be away from the position of the mobile hopper when returning to avoid interference with the mobile hopper in transmission. The servo motor, conveyor belt, feeding belt, electronic valve, push rod motor and other electric drive devices in the whole machine of this technical solution are all connected to the control panel for automatic control.

[0033] In the present invention, several mobile hoppers 3 are evenly arranged on the conveyor belt 2 and fastened with screws. Holes can be set at the bottom of the mobile hopper to fasten it to the conveyor belt through screws, and the distance between each mobile hopper is consistent. In addition to the means of screw installation, other fastening methods such as glue and buckles can also be used.

[0034] The feeding structure 4 of the present invention includes a feeding belt 41 which is transversely arranged on one side of the front section of the conveyor belt 2. The feeding belt 41 feeds materials from the side of the conveyor belt 2. The feeding belt 41 is arranged to be inclined toward the front side. A baffle 42 is fixed on the front side of the feeding belt 41 to prevent the materials from escaping. The side of the front section of the conveyor belt is the side of the transmission start end of the conveyor belt. Since the feeding belt is arranged to be inclined toward the front side, the feeding belt is in an oblique state when the medicine spoon is sent to the conveyor belt. The baffle can prevent the medicine spoon from being displaced or escaping from the feeding belt during the transmission process.

[0035] The blanking structure 5 described in the present invention includes a blanking box body 51 arranged on the right side of the rear end of the conveyor belt 2, and a plurality of groups of synchronously movable funnels 52 are evenly distributed inside the blanking box body 51, and each group of the funnels 52 is provided with two leak plates 53, namely a fixed leak plate 531 and a movable leak plate 532. The movable leak plate 532 is hinged between the two walls of the blanking box body 51 through an axis, and a gear 55 is provided at one end of the axis. A rack 56 for synchronously driving each gear 55 is provided on one side of the blanking box body 51, and the rack 56 is driven by a push rod motor to reciprocate linearly. A plurality of convex teeth 54 are provided at the bottom of the leak plate 53, and the convex teeth 54 of the fixed leak plate 531 and the movable leak plate 532 are staggered and can bite each other. The blanking box can receive the medicine spoons sent from the conveyor belt. The working activity state of multiple groups of funnels is synchronous activity, that is, the action and opening and closing timing are the same. Each group of funnels set inside can be used to push the medicine spoons on the corresponding multiple mobile hoppers at the same time, so that multiple medicine spoons can be dropped in the funnel each time, and this is repeated to maintain uninterrupted material discharge. Each group of funnels is composed of two leak plates, and the bottom of the leak plate has convex teeth and the convex teeth are offset from the convex teeth at the bottom of the other corresponding leak plate, so the closed state is very stable. In addition, the shape of the two leak plates in this technology is V-shaped when the bottom is closed, so the position of the material in the bottom of the two leak plates when biting is the narrowest part of the bottom of the V-shape, and therefore, the state of multiple groups of funnels when dropping is consistent. The movable leak plate is movable, and the fixed leak plate is fixed to the blanking box. Through single-sided material discharge, the material drop position can be more accurate. Each movable leak plate is synchronously opened and closed by the gear driven by the rack.

[0036] In the present invention, a support frame 21 is arranged above the conveyor belt 2, and the push structure 6 and the return structure 7 are both arranged on the support frame 21. The push structure 6 includes a push component 61 and an X-axis drive structure 62 that drives it to move left and right, and the return structure 7 includes a fixed hopper 71 and a Z-axis drive structure 72 that drives the push component 6 to move up and down in the fixed hopper 71. The support frame is fixed on the base and is located above the conveyor belt. When the push component is not pushed out, it is at the output end of the conveyor belt and at the position of the opposite blanking structure. The X-axis drive structure is on the support frame. When the X-axis drive structure is started, it drives the push component to reciprocate along the X-axis. The function of the fixed hopper is to align each group of funnels in the blanking box, so that the material in the mobile hopper can be directly sent into each group of funnels after being pushed into the fixed hopper. The Z-axis drive structure can drive the push component to move up and down, so that it can be separated from the fixed hopper and the mobile hopper, and no interference will occur when the X-axis is returned. The starting position of the Z-axis drive structure is above the funnel.

[0037] The pushing parts 61 described in the present invention are provided with several parts, which are composed of a mounting part 611 and several push plates 612 arranged below the mounting part 611. In this technical solution, there are two pushing parts, namely two mounting parts, and there are five bottom push plates in total, which are respectively distributed below the two mounting parts. The number of push plates corresponds to the number of groups of funnels. In this technical solution, the number of groups of funnels is set to 5 groups. The function of the mounting part is to connect the X-axis drive structure and the Z-axis drive structure. The function of the push plate is to drive the push plate to push the medicine spoon in the mobile hopper and the fixed hopper into the blanking structure when the two drive structures are started.

[0038] The X-axis driving structure 62 of the present invention includes a slide rail 621 arranged on the front and rear sides of the top of the support frame 21, and a reciprocating movable plate 622 is installed on the slide rails 621 on both sides. A fixed-point rotating pulley 623 is arranged on the left and right sides of the top of the support frame 21, one of the pulleys 623 is driven by a servo motor, and a belt 624 is sleeved on the outside of the two pulleys 623. The movable plate 622 is fixedly connected to one of the positions of the belt 624 so that when the belt 624 rotates, the movable plate 622 can be driven to move on the slide rail 621. The slide rail is used for the movable plate to move linearly, and the pulley is started to rotate by the servo motor to operate the belt. Since one position on the belt is fixedly connected to the movable plate, the movable plate can be driven to move back and forth. Since the Z-axis driving structure is installed on the movable plate, the pushing component is installed on the Z-axis driving structure, so the movement of the movable plate will drive the pushing component to move.

[0039] The Z-axis driving structure 72 of the present invention includes a plurality of cylinders 721 arranged on a movable plate 622, a guide block 722 is arranged outside the cylinder 721, a guide plate 723 is fixedly arranged on the movable end of the cylinder 721, a guide groove 724 is provided on the guide plate 723 and is limitedly matched with the guide block 722, and the mounting member 611 is connected to the guide plate 723. The cylinder is connected to an external air compressor, and the opening and closing of the cylinder can be installed on the cylinder or the air pipe through an electronic valve. When the movable end of the cylinder is working, the guide plate can move straight up and down due to the limiting effect of the guide groove and the guide block, so that the mounting member on the guide plate can move up and down at the same time to realize the Z-axis movement. The starting time of the Z-axis driving structure is when the push plate pushes the medicine spoon into the funnel group, and the push plate starts to move upward after being in a position away from the fixed hopper, and then the X-axis driving structure drives the push plate back to one side of the movable hopper, waiting for the conveyor belt to re-transmit a sufficient number of medicine spoons.

[0040] The fixed hopper 71 of the present invention is fixedly arranged between the material dropping box 51 and the conveyor belt 2, and is aligned with the position of each group of hoppers 52. The fixed hopper 71 and the movable hopper 3 have the same appearance. The fixed hopper allows each medicine spoon to accurately fall into the position of each group of hoppers. When the conveyor belt drives the medicine spoon of the movable hopper to the position corresponding to the fixed hopper, the conveyor belt temporarily stops operating. At this time, the fixed hopper and the movable hopper are completely aligned, which facilitates the pushing of the medicine spoon.

[0041] The movable hopper 3 and the fixed hopper 71 described in the present invention are both concave, and the limiting structure 8 includes a plurality of limiting grooves 81 provided on each inner side wall of the movable hopper 3 and the fixed hopper 71, and a plurality of limiting protrusions 82 provided on the outer wall of the push plate 612, and the limiting protrusions 82 can be embedded in the limiting grooves 81 for limited sliding. When the medicine spoon is in the movable hopper or the fixed hopper, the push plate pushes the medicine spoon, and under the action of each limiting groove and limiting protrusion, the movement of the push plate will remain in an upright state, and there will be no large gap between the push plate and the movable hopper and the fixed hopper, so the medicine spoon will not stick due to its characteristics, volume, and weight and thus fall into the gap between the push plate and the hopper.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
