Description

Technical Field

[0001] The invention relates to a shelf production device, in particular to a shelf pusher automatic assembly device. Background Art

[0002] A pusher is a device installed on a container. It uses a pushing mechanism to compact a whole row of goods (such as cigarette boxes) so that the whole row of goods is neatly stacked, and the goods are pushed automatically at the same time. After the counter staff removes the outermost goods, the pushing mechanism automatically pushes the remaining goods outward and compacts the remaining goods again. It can be used as a platform for displaying and selling goods, making it easier for counter staff to take goods and reducing their workload. For example, the utility model patent with authorization announcement number CN209651342U discloses a cigarette pusher. The cigarette pusher automatically works by the rebound of the pressure strip of the pushing mechanism, ensuring that the cigarettes loaded in the cigarette pusher are neatly pushed outward.

[0003] Among them, see Figure 1-2 The existing thruster mainly includes a base plate 1, a thrust seat 2 and a coil spring 3. The base plate 1 is provided with a sliding hole 1-1 and a slide rail 1-2; the base plate 1 is provided with a fixed buckle column 1-3 and a first avoidance hole 1-4 for avoiding the coil spring 3 from being connected to the fixed buckle column 1-3, and the end of the fixed buckle column 1-3 is provided with an inclined guide surface; the bottom of the thrust seat 2 extends into the sliding hole 1-1, and the thrust seat 2 is provided with a sliding groove that cooperates with the slide rail 1-2; the thrust seat 2 is provided with an installation slot for placing the coil spring 3 and a second avoidance hole 2-1 for avoiding the coil spring 3 from being connected to the base plate 1; the end of the coil spring 3 is provided with a buckle hole for cooperating with the fixed buckle column 1-3.

[0004] However, existing thrusters mainly rely on manual assembly, which is time-consuming and labor-intensive, and production efficiency needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned problems and provide an automated assembly device for shelf pushers, which can automatically complete the assembly of pushers without manual participation, has a high degree of automation, and is conducive to improving production efficiency.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0008] The feeding mechanism includes a bottom plate feeding mechanism, a push seat feeding mechanism and a coil spring feeding mechanism;

[0009] The transport mechanism includes a base plate transport mechanism for transporting the base plate from the base plate feeding mechanism to the assembly station, a propulsion seat transport mechanism for transporting the propulsion seat from the propulsion seat feeding mechanism and assembling it on the base plate located in the assembly station, and a coil spring transport mechanism for transporting the coil spring from the coil spring feeding mechanism to the propulsion seat located on the base plate;

[0010] The assembly clamping mechanism includes a first clamping mechanism, a second clamping mechanism and a clamping transverse driving mechanism for driving the first clamping mechanism and the second clamping mechanism to move transversely; during the assembly work, the first clamping mechanism is used to clamp the end of the coil spring extending from the second avoidance hole of the propulsion seat; the first clamping mechanism is driven to move toward the first avoidance hole of the base plate by the clamping transverse driving mechanism until the coil spring is stretched to a specified length; the second clamping mechanism is clamped on the coil spring by the second clamping mechanism adjacent to the first clamping mechanism, and the clamping point of the second clamping mechanism is located between the second avoidance hole and the end of the coil spring; the first clamping mechanism loosens the coil spring so that the end of the coil spring is exposed; the second clamping mechanism is driven to move toward the first avoidance hole of the base plate by the clamping transverse driving mechanism until the end of the coil spring passes through the first avoidance hole of the base plate and is buckled on the fixed buckle column.

[0011] The working principle of the above-mentioned shelf pusher automated assembly equipment is:

[0012] During operation, the base plate, propulsion seat and coil spring are loaded in order through the base plate loading mechanism, the propulsion seat loading mechanism and the coil spring loading mechanism respectively; the base plate is first transported from the base plate loading mechanism to the assembly station through the base plate transporting mechanism, and then the propulsion seat is transported from the propulsion seat loading mechanism through the propulsion seat transporting mechanism and assembled to the base plate located in the assembly station. The specific assembly operation is: the propulsion seat transporting mechanism transports the propulsion seat to the top of the base plate, and makes the orientation of the propulsion seat 90° different from the assembled orientation, so that the bottom of the propulsion seat enters the sliding hole of the base plate, and the propulsion seat transporting mechanism drives the propulsion seat downward. When the bottom of the propulsion seat enters the sliding hole of the base plate, the propulsion seat transporting mechanism drives the propulsion seat to rotate horizontally 90 degrees (in this process, the base plate will undergo slight elastic deformation to cooperate with the operation of the propulsion seat), so that the slide rail of the base plate cooperates with the slide groove of the propulsion seat, and the installation of the propulsion seat is completed.

[0013] The coil spring is transported from the coil spring feeding mechanism to the propulsion seat on the base plate through the coil spring transport mechanism. At this time, the body of the coil spring is located in the installation slot of the propulsion seat, and the end of the coil spring extends beyond the propulsion seat through the second avoidance hole; the end of the coil spring is clamped by the first clamping mechanism, and the first clamping mechanism is driven to move toward the first avoidance hole of the base plate through the clamping transverse drive mechanism until the coil spring is stretched to a specified length; the coil spring is clamped by a second clamping mechanism adjacent to the first clamping mechanism, and the clamping point of the second clamping mechanism is located between the second avoidance hole and the end of the coil spring; then the first clamping mechanism releases the coil spring, exposing the end of the coil spring; the second clamping mechanism is driven to move toward the first avoidance hole of the base plate through the clamping transverse drive mechanism until the end of the coil spring passes through the first avoidance hole of the base plate and is buckled on the fixed buckle column.

At this time, the first grabbing terminal is located directly above the propulsion seat to be transported. At the same time or before this, the posture of the first grabbing terminal is adjusted by the first propulsion seat rotation drive mechanism to prepare for grabbing the propulsion seat; the first grabbing terminal is driven downward to approach the propulsion seat by the propulsion seat vertical drive mechanism until the first grabbing terminal grabs the propulsion seat; the second grabbing terminal is driven downward to approach the propulsion seat by the propulsion seat vertical drive mechanism until the first grabbing terminal grabs the propulsion seat; the second grabbing terminal is driven downward to approach the propulsion seat by the propulsion seat vertical drive mechanism A grabbing terminal moves upward a certain distance, and the first grabbing terminal is driven to move horizontally a certain distance by the transport horizontal drive mechanism, and the first grabbing terminal is driven to rotate downward by the second propulsion seat rotation drive mechanism.
