Description

Technical Field

[0001] The invention relates to shelf production equipment, in particular to a shelf plug installation machine. Background Art

[0002] Supermarkets and convenience stores often use self-loading slide racks to display goods, reducing inventory management costs and facilitating easy access for customers. Traditional self-loading slide racks consist of two components: a self-loading slide and a support frame. These components are assembled and installed in a refrigerated unit (such as a freezer). The support frame is supported by the unit's support structure, and the self-loading slide is mounted on top of the support frame.

[0003] Existing deadweight slides primarily consist of rollers, a rolling frame, edge banding, and plugs. The rolling frame is equipped with multiple pairs of mounting slots evenly spaced along its length, each pair comprising two mounting slots. Multiple rollers are sequentially positioned within these multiple pairs of slots. The two edge bands are fixedly wrapped around the sides of the rolling frame, and the rolling frame, located in the middle, is secured in place by two plugs at either end. Furthermore, the assembly process for existing deadweight slides primarily involves placing the rollers on the rolling frame, pushing the frame into the two edge banding slots, inserting the two plugs at either end of the rolling frame, and finally, using a stamping mechanism to stamp the edge banding in place to mate with the plugs, causing it to bend toward the plugs, thereby securing the plugs.

[0004] The assembly of the self-weight slideway is mainly done manually, especially installing the plugs at both ends of the semi-finished slideway (including assembled rollers, roller frames and edge banding), which is time-consuming and labor-intensive, and the work 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 a shelf plug installation machine, which can automatically complete the installation of the plug, save time and labor, and help improve work efficiency.

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

[0007] A shelf plug installation machine comprises an automatic feeding mechanism, a transfer pushing mechanism and a forward mechanism; the automatic feeding mechanism comprises a vibrating plate; the transfer pushing mechanism comprises a transfer platform and a pushing mechanism, the transfer platform comprises a first transfer platform, a second transfer platform and a guide platform; the pushing mechanism comprises a front pushing mechanism and a rear pushing mechanism, the front pushing mechanism comprises a first pushing mechanism and a second pushing mechanism, the pushing direction of the first pushing mechanism is perpendicular to the pushing direction of the second pushing mechanism; the forward mechanism comprises a direction detecting mechanism and a reversing mechanism, the direction detecting mechanism is used to detect the direction of the plug; the reversing mechanism comprises a rotating platform and a rotating driving mechanism for driving the rotating platform to rotate; the first transfer platform is located between the first pushing mechanism and the rotating platform; the rotating platform is located between the second pushing mechanism and the second transfer platform;

[0008] The plugs are sorted and loaded in sequence through the automatic loading mechanism, and the plugs are transported to the first transfer platform. The plugs on the first transfer platform are pushed to the rotating platform by the first pushing mechanism. The rotating platform is driven to rotate in the corresponding direction by the rotary drive mechanism, and the plugs on the rotating platform are pushed to the second transfer platform by the second pushing mechanism. Before or at the same time, the semi-finished product slide is transported to the front of the rear pushing mechanism; the plugs are pushed to the end of the semi-finished product slide by the rear pushing mechanism; and the deadweight slide is transported downward.

[0009] The working principle of the above-mentioned shelf plug installation machine is as follows:

[0010] During operation, the plugs are automatically sorted and transported out through the vibration disk. The plugs are first transported to the first transfer platform, and the plugs on the first transfer platform are pushed to the rotating platform by the first pushing mechanism; before that, the direction of the loaded plugs is detected by the direction detection mechanism, and the corresponding driving instructions are sent to the rotating drive mechanism through the control system. The driving instructions include 90° forward rotation and 90° reverse rotation. Assuming that 90° forward rotation means that the outer end of the plug is close to the first pushing mechanism when it is on the first transfer platform, then 90° reverse rotation is the opposite; the corresponding driving instructions are executed by the rotating drive mechanism to drive the rotating platform to rotate in the corresponding direction, and the plugs on the rotating platform are pushed to the second transfer platform by the second pushing mechanism.

[0011] Before or at the same time, the semi-finished product slide is transported to the front of the rear pushing mechanism; the plug is pushed to the end of the semi-finished product slide by the rear pushing mechanism, and finally the self-weight slide is transported downward.

[0012] In a preferred embodiment of the present invention, the first pushing mechanism includes a first pushing plate and a first pushing drive mechanism, and the first pushing plate is connected to a driving end of the first pushing drive mechanism.

[0013] In a preferred embodiment of the present invention, the second pushing mechanism includes a second pushing plate and a second pushing drive mechanism, and the second pushing plate is connected to the driving end of the second pushing drive mechanism.

[0014] In a preferred embodiment of the present invention, the rear pushing mechanism includes a third pushing mechanism and a fourth pushing mechanism;

[0015] The pushing direction of the third pushing mechanism is parallel to the pushing direction of the first pushing mechanism; the pushing direction of the third pushing mechanism is perpendicular to the pushing direction of the fourth pushing mechanism, and the pushing direction of the fourth pushing mechanism is perpendicular to the conveying direction of the semi-finished product slide;

[0016] The second transfer platform extends in front of the third pushing mechanism and the fourth pushing mechanism at the same time, and the second transfer platform is located between the fourth pushing mechanism and the guide platform. Through the above structure, when the plug is pushed onto the second transfer platform, it is now located directly in front of the third pushing mechanism. The third pushing mechanism pushes the plug forward so that the plug is located directly in front of the fourth pushing mechanism, and then the fourth pushing mechanism pushes the plug to the end of the semi-finished product slide. Furthermore, the plug pushing work is completed by alternating multiple pushing mechanisms. Its important role is that, based on the above structural layout, two sets of plug installation machines can be set on both sides of the conveying channel of the semi-finished product slide, so that the installation work of the plugs at both ends of the semi-finished product slide can be performed simultaneously. The structural layout is very clever and compact.

[0017] In a preferred embodiment of the present invention, the third pushing mechanism includes a third pushing plate and a third pushing drive mechanism, and the third pushing plate is connected to the driving end of the third pushing drive mechanism.

[0018] In a preferred embodiment of the present invention, the fourth pushing mechanism includes a fourth pushing plate and a fourth pushing drive mechanism, and the fourth pushing plate is connected to the driving end of the fourth pushing drive mechanism.

[0019] A preferred embodiment of the present invention further comprises a posture control mechanism, wherein the posture control mechanism comprises a posture detection mechanism for detecting the posture of the front and back sides of the plug and a rejection mechanism for rejecting the plug with incorrect posture.

[0020] Furthermore, the rotating platform includes a rotating base and a rotating upper base, and the rotating upper base is fixedly arranged above the rotating base;

[0021] The posture detection mechanism includes two detection components, each of which includes a photoelectric switch, a swing sensor block, and a reset torsion spring; the photoelectric switch is fixedly mounted on a rotating base; one end of the swing sensor block is rotatably connected to the rotating base, and the swing sensor block is provided with a conical boss; the conical boss extends upward through a relief hole in the rotating upper base; the reset torsion spring is sleeved on the rotation center of the swing sensor block, and the two ends of the reset torsion spring are respectively fixedly connected to the swing sensor block and the rotating base;

[0022] The two swing sensing blocks are staggered along the direction in which the plug moves on the rotating platform;

[0023] When the conical boss of the swing sensing block is pressed down by the bottom surface of the plug, the other end of the swing sensing block swings into the sensing slot of the photoelectric switch.

[0024] In actual operation, after the plug is automatically sorted and transported out by the vibrating disk, the plug moves forward in a flat position. At this time, the plug may be facing down (one end of the back of the plug is provided with an empty groove), or it may be facing up. Therefore, it is necessary to remove the plugs with incorrect postures and leave qualified plugs to ensure that the plugs are assembled in the correct posture. Through the above structure, when the plug moves to the rotating upper seat, if both swinging sensing blocks swing to the sensing slot of the photoelectric switch, the photoelectric switch detects the relevant signal, indicating that the plug is facing up, and notifies the removal mechanism to remove the plug with the incorrect posture; if only one of the swinging sensing blocks swings to the sensing slot of the photoelectric switch, the corresponding photoelectric switch detects the relevant signal, indicating that the plug is facing down.

[0025] Furthermore, the rejection mechanism includes a transition support plate and a swing drive mechanism for driving the transition support plate to swing, one end of the transition support plate is rotatably connected to the mounting plate; the swing drive mechanism includes a swing drive cylinder, the cylinder body of the swing drive cylinder is rotatably connected to the fixing frame, and the telescopic rod of the swing drive cylinder is rotatably connected to the transition support plate;

[0026] In the non-rejecting state, the transition support plate is flushly located in the transition space between the rotating platform and the second transfer platform; in the non-rejecting state, the transition support plate is tiltedly located below the transition space between the rotating platform and the second transfer platform.

[0027] A preferred embodiment of the present invention further comprises a stamping locking mechanism disposed below the conveying channel of the semi-finished product slideway, the stamping locking mechanism comprising a stamping head and a stamping drive mechanism, the top of the stamping head being provided with two stamping bosses, both of which being provided with inclined stamping surfaces;

[0028] When the plug is pushed into the end of the semi-finished product slide, the punching head is driven upward by the punching drive mechanism, and the end of the bottom surface of the edge band is punched upward by the punching surface of the punching head to form a flange extending into the empty groove of the plug, thereby fixing the plug.

[0029] Furthermore, a pressing plate is provided on the guide platform, and the pressing plate is connected to the driving end of the downward driving mechanism.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The shelf plug installation machine of the present invention can automatically complete the installation of the plug, saving time and labor, and helping to improve work efficiency.

[0032] 2. By setting up a direction detection mechanism and a reversing mechanism, the direction of the plug that comes out of the material is first detected by the direction detection mechanism, and the corresponding drive instruction is sent to the rotary drive mechanism through the control system. The rotary drive mechanism then executes the corresponding drive instruction to drive the rotary platform to rotate in the corresponding direction. In this way, the correct direction can be obtained, and thus a qualified deadweight slide can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS
