Description

Technical Field

[0001] The invention relates to the field of calculating tools, and in particular to an automatic discharging device for abacus beads. Background Art

[0002] Abacus is a widely used mathematical calculation tool. During the production process of abacus, the beads need to be strung on the rods first, and then the rods are connected to the abacus body. However, the stringing of the beads and the rods is currently done manually, which has low production efficiency and high production costs. In addition, the number of beads may be wrong due to negligence during the manual stringing process, resulting in a high rework rate. Summary of the invention

[0003] The present invention provides an automatic discharging device for counting beads, which overcomes the shortcomings of the background technology. The technical solution adopted by the present invention to solve the technical problem is:

[0004] An automatic discharging device for counting beads, comprising a machine platform, a feed hopper, a swing drive mechanism, a material blocking mechanism, a material guiding mechanism and a discharging mechanism, wherein the swing drive mechanism is mounted on the machine platform and connected to the feed hopper to drive the feed hopper to swing back and forth, a plurality of feed guide rails are arranged on the bottom surface of the feed hopper, the material blocking mechanism is mounted at the outlet of the feed hopper and can open or close the outlet of the feed hopper, the material guiding mechanism comprises an inclined material guiding plate, the material guiding plate is provided with a plurality of material guiding grooves, the discharging mechanism comprises a discharging driver and a discharging plate, the discharging driver is mounted on the machine platform and transmission-connected to the discharging plate, the discharging plate is provided with a plurality of discharging grooves, and the discharging plate moves between a first position where the discharging groove corresponds to the end of the material guiding groove and a second position where the discharging groove leaves the end of the material guiding groove;

[0005] During the forward and backward swinging of the feed hopper, the beads can be arranged front and back in the feed guide rail. When the feed guide rail is connected to the guide groove one by one and the blocking mechanism opens the feed hopper outlet, the beads can slide down along the guide groove to the discharge groove. Driven by the discharge driver, the discharge plate moves from the first position to the second position to proceed to the next process.

[0006] In a preferred embodiment: the swing drive mechanism includes a swing cylinder, a transmission push plate and a transmission block. The swing cylinder is installed on the machine platform and is transmission-connected to the transmission push plate. The transmission push plate is fixedly connected under the transmission block. The transmission block is rotatably mounted on the machine platform, and the feed hopper is fixedly connected to the transmission block.

[0007] In a preferred embodiment: the material blocking mechanism includes a material blocking frame and a plurality of material blocking cylinders, the material blocking frame is fixedly connected to the feed hopper, a socket is provided at the end of each feed guide rail, the material blocking cylinders and the sockets are arranged one-to-one, and the cylinder arms of the material blocking cylinders can move between a closed position inserted into the socket and an open position away from the socket.

[0008] In a preferred embodiment: the discharge plate is further provided with a series groove, the series groove is connected to all the discharge grooves, and the two ends of the series groove extend to the two side surfaces of the discharge plate respectively.

[0009] In a preferred embodiment, the discharge groove is semicircular, and the series grooves extend along the central axis of the discharge groove.

[0010] In a preferred embodiment: it also includes a sensing mechanism, which includes a sensing frame and a plurality of sensors. The sensing frame is fixed to the machine platform and is located above the material guide plate. The sensors are installed on the sensing frame and are arranged one by one with the material guide troughs.

[0011] In a preferred embodiment: the material guiding mechanism further comprises a transparent cover plate, and the cover plate is placed on the material guiding plate.

[0012] Compared with the background technology, this technical solution has the following advantages:

[0013] 1. First, close the outlet of the feed hopper through the material blocking mechanism, then pile the beads in the feed hopper, and drive the feed hopper to swing back and forth through the swing drive mechanism, so that the beads at the bottom can be neatly arranged along the feed guide rail; then, when the feed hopper is swung until the end of the feed guide rail is connected with the top of the guide trough, open the outlet of the feed hopper through the material blocking mechanism. Since the guide plate is arranged at an angle, the feed hopper is also arranged at an angle at this time in order to connect the end of the feed guide rail with the top of the guide trough, and the discharge plate is in the initial position of the first position, the beads at the bottom of the feed hopper slide downward along the guide trough until the beads fall into the discharge groove; finally, the discharge drive drives the discharge plate to move to the second position, and the next step of inserting the rod into the beads for stringing can be carried out.

[0014] The automatic abacus bead arranging device can automatically and neatly arrange a plurality of abacus beads in a row to wait for being strung together, without the need for manual stringing one by one, thereby greatly improving production efficiency, reducing labor costs, and having a low stringing error rate and rework rate.

[0015] 2. The swing cylinder drives the transmission push plate to swing back and forth, and then drives the transmission block to swing back and forth. The transmission block then drives the feed hopper to swing back and forth. During the reciprocating swing of the feed hopper, the beads in the feed hopper can be arranged vertically along each feed guide rail without manual placement, thereby improving production efficiency.

[0016] 3. The cylinder arm of the material-blocking cylinder can move between a closed position inserted into the socket and an open position left from the socket. When the feed hopper is swinging, the material-blocking cylinder can close the feed hopper outlet to prevent the beads in the feed hopper from falling out of the feed hopper. When the end of the feed guide rail is connected to the top of the guide trough, the cylinder arm of the material-blocking cylinder can leave the socket to allow the beads to move from the feed guide rail to the guide trough.

[0017] 4. Both ends of the string groove extend to the two sides of the discharge plate, which can facilitate the insertion of the plunger in the next step and is easy to use.

[0018] 5. The sensor is installed on the sensor frame and arranged one by one with the material guide trough. When the beads in the material guide trough reach the position of the sensor, the sensor can send a signal to control the material blocking mechanism to close the feed hopper outlet to avoid too many beads in the material guide trough affecting subsequent movement.

[0019] 6. The transparent cover can not only ensure that the beads in the guide trough will not fall out, but also allow the movement of the beads to be observed at any time, making it easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
