Description

Technical Field

[0001] The invention relates to ceramic tile packaging equipment, in particular to a corner folding device for ceramic tile packaging. Background Art

[0002] Ceramic tile refers to a kind of acid and alkali resistant porcelain or stone material formed by grinding, mixing, pressing, glazing, sintering and other processes of refractory metal oxides and semi-metal oxides. Among them, ceramic tiles are widely used in the construction or decoration industry due to their good flatness, high flexural strength, good wear resistance, resistance to heavy pressure, and not easy to wear. With the development of the real estate industry, the demand for ceramic tiles has also increased year by year.

[0003] After the ceramic tiles are processed, they need to be packaged to avoid breakage and scratches during transportation and storage. However, the traditional packaging process is mainly completed manually, and the work efficiency is very low. In order to solve the problem of low efficiency, some semi-enclosed ceramic tile packaging equipment has been proposed in the prior art. The ceramic tile packaging equipment mainly includes a long side folding mechanism, a wide side folding mechanism and a small side folding mechanism, which respectively fold the long side (parallel to the conveying direction of the conveying device), the wide side (perpendicular to the conveying direction of the conveying device) and the small side (the small side is set on the long side or the wide side) of the cardboard and wrap them on the outside of the ceramic tile to form a semi-enclosed package to avoid damage to the corners of the ceramic tile during transportation and storage. Although the above ceramic tile packaging equipment can automatically complete the packaging of ceramic tiles and greatly improve work efficiency, since the small side folding mechanism of the existing ceramic tile packaging equipment is fixedly arranged above the conveying channel of the conveying device, the following problems exist in the actual packaging process:

[0004] 1. The small edge folding mechanism needs to be installed on the conveying device through a mounting frame or other fixed structure. It is located on the outside of the conveying device (belt), occupies a large space, and is very inconvenient to repair and maintain the conveying device.

[0005] 2. Since the small edge folding mechanism is set above the conveying channel, when the tiles and cardboard (cardboard is placed under the tiles to be packaged) are conveyed to the packaging station, the small edge folding mechanism must first avoid the long side or wide side of the cardboard and fold upwards before it can move down close to the tiles to fold the small side. The multiple operation steps of the above packaging process need to be carried out step by step, resulting in a long packaging time for a single tile, and the packaging efficiency needs to be further improved. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems and provide a corner folding device for tile packaging, which can simultaneously move upward and close to the tile when the long side or wide side of the cardboard is folded upward, thereby shortening the packaging time of a single tile and effectively improving the packaging efficiency; and it occupies a small space, which is convenient for the maintenance of the conveying device.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A corner folding device for ceramic tile packaging, comprising a small edge folding mechanism for folding a small edge of a paperboard onto a side surface of a ceramic tile and a driving mechanism for driving the small edge folding mechanism to move up and down, wherein the small edge folding mechanism comprises a small edge pushing member and a folding driving mechanism for driving the small edge pushing member to move close to or away from the small edge of the paperboard;

[0009] In a non-working state, the small edge folding mechanism is located below the conveying channel of the conveying device; in a working state, when the long side or the wide side of the cardboard is folded upward, the driving mechanism drives the small edge pusher upward to approach the conveying channel.

[0010] The working principle of the above-mentioned corner bending device for ceramic tile packaging is as follows:

[0011] During operation, the conveying device conveys the tiles and cardboard (cardboard is placed under the tiles to be packaged) to the packaging station, and the small edge folding mechanism is located below the conveying channel of the conveying device. Assuming that the small edge on the cardboard is set on the wide edge of the cardboard (perpendicular to the conveying direction of the conveying device), the wide edge of the cardboard is folded upward by the wide edge folding mechanism to surround the side of the tile perpendicular to the conveying direction of the conveying device. At the same time, the driving mechanism drives the small edge pusher to move upward to the conveying channel, so that the small edge pusher moves to the front or rear of the small edge, and then the folding driving mechanism drives the small edge pusher to approach the small edge of the cardboard, and then the small edge pusher bends the small edge of the cardboard in the direction close to the tile, so that the small edge of the cardboard is close to the side of the tile parallel to the conveying direction of the conveying device.

[0012] Next, the long edge folding mechanism folds the long edge of the cardboard upward, wraps the small edge and wraps it outside the side of the tile parallel to the conveying direction of the conveying device, and uses other limiting mechanisms to press the folded wide and long edges, and then conveys it to other processing stations. The folding drive mechanism drives the small edge pusher away from the small edge, and the drive mechanism drives the entire small edge folding mechanism to reset.

[0013] In a preferred embodiment of the present invention, when the small edge pusher approaches the small edge, it acts on the small edge in an outwardly inclined posture. In this way, the distance between the small edge pusher and the side edge at the corresponding position of the tile can be increased, preventing the front end of the small edge pusher from forming a "scissor structure" with the side edge at the corresponding position of the tile, thereby preventing the small edge from being sheared and damaged.

[0014] A preferred solution of the present invention, wherein the small edge folding mechanism also includes an extrusion drive mechanism for driving the small edge pusher to press the small edge against the side of the tile. In actual application, when the small edge pusher is prevented from approaching the small edge, in order to prevent the front end of the small edge pusher from forming a "scissors structure" with the side edge at the corresponding position of the tile, the distance between the small edge pusher and the side edge at the corresponding position of the tile is often appropriately increased, thereby avoiding the small edge from being sheared. Although this will not form a "scissors structure", it will cause the problem of the small edge not being folded into place. In order to solve the above problem, the present invention preferably sets an extrusion drive mechanism, and in the later stage of the small edge bending, drives the small edge pusher to press the small edge against the side of the tile, so that the small edge fits in place on the corresponding side of the tile.

[0015] Preferably, the extrusion drive mechanism includes a pneumatic push rod, which is arranged on a moving frame of the folding drive mechanism; the small edge push piece is hinged on the moving frame of the folding drive mechanism, and the two ends of the small edge push piece are respectively a bending drive part and a force-bearing part with the hinge center of the small edge push piece as the boundary; the pneumatic push rod is provided with a driving rod acting on the force-bearing part of the small edge push piece. Through the above structure, when the driving rod of the pneumatic push rod pushes the force-bearing part of the small edge push piece, the bending driving part squeezes the small edge onto the side of the tile around the hinge center.

[0016] Furthermore, a return spring is provided between the movable frame of the folding drive mechanism and the force-bearing part of the small edge pusher. When the small edge is squeezed against the side of the tile, the driving rod of the pneumatic push rod is reset, and the return spring releases the potential energy to pull the small edge pusher to reset, so that the bending drive part of the small edge pusher is away from the side of the tile.

[0017] In a preferred embodiment of the present invention, the driving mechanism is a rotary driving mechanism, which drives the small side pusher to rotate upward and approach the conveying channel in the working state. Of course, the driving mechanism can also be a vertical driving mechanism, which drives the small side pusher vertically upward and approach the conveying channel in the working state.

[0018] Preferably, the rotary drive mechanism includes a rotary drive cylinder and a rotary transmission assembly, the rotary transmission assembly includes a rotary shaft and a rotary pendulum, the rotary shaft is rotatably connected to the frame of the conveying device, and the cylinder body of the rotary drive cylinder is hinged on the mounting frame; one end of the rotary pendulum is fixedly connected to the rotary shaft, and the other end is hinged to the telescopic rod of the rotary drive cylinder; the small edge folding mechanism is fixedly set on the rotary shaft through a fixed plate.

[0019] Furthermore, the axis of the rotating shaft is perpendicular to the conveying direction of the conveying device; one end of the wide edge folding mechanism for folding the wide edge of the cardboard is fixed on the rotating shaft; in a non-working state, the wide edge folding mechanism is located below the conveying channel of the conveying device; in a working state, the rotating shaft drives the wide edge folding mechanism and the small edge folding mechanism to rotate upward and close to the conveying channel. Through the above structure, the wide edge folding mechanism and the small edge folding mechanism share a driving mechanism, which can not only simplify the structure and reduce the manufacturing cost; but also because the wide edge folding mechanism and the small edge folding mechanism are integrated on the rotating shaft at the same time, when it is necessary to adjust the position of the wide edge folding mechanism according to the length of the tile, the adjustment of the wide edge folding mechanism and the small edge folding mechanism can be completed at the same time, and the operation is very convenient.

[0020] In a preferred embodiment of the present invention, the hemming drive mechanism comprises a moving frame and a hemming drive cylinder, and the hemming drive cylinder is arranged on a rotating shaft through the fixing plate;

[0021] The moving frame is fixedly connected to the telescopic rod of the folding driving cylinder, and the small edge pushing piece is arranged on the moving frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Since the folding device in the present invention is located below the conveying channel of the conveying device in a non-working state, when the long side or wide side of the cardboard is folded upward, it can be synchronously moved upward close to the conveying channel without interference, and there is no need to wait for the long side or wide side of the cardboard to complete the folding. This is equivalent to overlapping the time for driving the folding mechanism to approach the conveying channel with the folding time of the long side or wide side, thereby shortening the packaging time of a single tile and effectively improving the packaging efficiency.

[0024] 2. The corner folding device in the present invention is arranged below the conveying passage of the tiles, which occupies a small space and is convenient for the repair and maintenance of the conveying device. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0033] Example 1

[0034] See also Figure 1-5 The corner folding device for ceramic tile packaging in this embodiment is arranged on the side of the conveying device 1, and includes a small edge folding mechanism for folding the small edge 1b of the cardboard b on the side of the ceramic tile a and a driving mechanism for driving the small edge folding mechanism to move up and down. The small edge folding mechanism includes a small edge pusher 2 and a folding driving mechanism for driving the small edge pusher 2 to approach or move away from the small edge 1b of the cardboard b; in a non-working state, the small edge folding mechanism is located below the conveying channel of the conveying device 1; in a working state, when the long edge 3b or the wide edge 2b of the cardboard b is folded upward, the driving mechanism drives the small edge pusher 2 to approach the conveying channel upward. Specifically, the small edge 1b of the cardboard b in this embodiment is arranged on the wide edge 2b of the cardboard b (perpendicular to the conveying direction of the conveying device 1).

[0035] See also Figure 6-12 When the small side pusher 2 approaches the small side 1b, it acts on the small side 1b in an outwardly inclined posture, such as Figure 7-8 This can increase the distance between the small edge pusher 2 and the side edge at the corresponding position of the tile a, preventing the front end of the small edge pusher 2 from forming a "scissor structure" with the side edge at the corresponding position of the tile a, thereby preventing the small edge 1b from being sheared and damaged.

[0036] See also Figure 6-12, the small edge folding mechanism also includes an extrusion drive mechanism for driving the small edge pusher 2 to press the small edge 1b to the side of the tile a. In actual application, when the small edge pusher 2 is prevented from approaching the small edge 1b, in order to prevent the front end of the small edge pusher 2 from forming a "scissors structure" with the side edges at the corresponding position of the tile a, the distance between the small edge pusher 2 and the side edges at the corresponding position of the tile a is often appropriately increased, thereby avoiding the small edge 1b from being sheared. Although this will not form a "scissors structure", it will cause the problem of the small edge 1b not being folded into place. In order to solve the above problem, the present invention preferably sets an extrusion drive mechanism, which drives the small edge pusher 2 to press the small edge 1b to the side of the tile a in the later stage of bending the small edge 1b, so that the small edge 1b fits in place on the corresponding side of the tile a, such as Fig. 9 .

Through the above structure, when the driving rod of the pneumatic push rod 3 pushes the force-bearing part 2-2 of the small edge pusher 2, the bending driving part 2-1 squeezes the small edge 1b onto the side of the tile a around the hinge center, as shown in FIG. Fig.11 A return spring 5 is provided between the moving frame 4 of the folding drive mechanism and the force-bearing portion 2-2 of the small edge pusher 2. When the small edge 1b is pressed against the side of the tile a, the driving rod of the pneumatic push rod 3 is reset, and the return spring 5 releases potential energy to pull the small edge pusher 2 to reset, so that the bending drive portion 2-1 of the small edge pusher 2 is away from the side of the tile a. Fig.12 .

[0038] See also Figure 1-9 , the driving mechanism is a rotary driving mechanism. In the working state, the rotary driving mechanism drives the small edge pusher 2 to rotate upward and approach the conveying channel. The rotary driving mechanism includes a rotary driving cylinder 6 and a rotary transmission assembly. The rotary transmission assembly includes a rotary shaft 7 and a rotary pendulum 8. The rotary shaft 7 is rotatably connected to the frame of the conveying device 1. The cylinder body of the rotary driving cylinder 6 is hinged on the mounting frame (not shown in the figure); one end of the rotary pendulum 8 is fixedly connected to the rotary shaft 7, and the other end is hinged to the telescopic rod of the rotary driving cylinder 6; the small edge folding mechanism is fixedly set on the rotary shaft 7 through a fixed plate 9. Of course, the rotary driving mechanism can also be other mechanisms that can realize rotary drive, such as a motor driving mechanism.

[0039] Furthermore, the axis of the rotating shaft 7 is perpendicular to the conveying direction of the conveying device 1; one end of the wide edge folding mechanism 10 for folding the wide edge 2b of the cardboard b is fixed on the rotating shaft 7; in the non-working state, the wide edge folding mechanism 10 is located below the conveying channel of the conveying device 1; in the working state, the rotating shaft 7 drives the wide edge folding mechanism 10 and the small edge folding mechanism to rotate upward and close to the conveying channel. Through the above structure, the wide edge folding mechanism 10 and the small edge folding mechanism share a driving mechanism, which can not only simplify the structure and reduce the manufacturing cost; but also because the wide edge folding mechanism 10 and the small edge folding mechanism are integrated on the rotating shaft 7 at the same time, when it is necessary to adjust the position of the wide edge folding mechanism 10 according to the length of the tile a, the adjustment of the wide edge folding mechanism 10 and the small edge folding mechanism can be completed at the same time, and the operation is very convenient.

Of course, the hem folding drive mechanism can also be other mechanisms capable of realizing linear drive, such as a motor drive mechanism.

[0041] See also Figure 1-12 The working principle of the corner bending device for ceramic tile packaging in this embodiment is as follows:

[0042] When working, the conveying device 1 conveys the tile a and the cardboard b (the cardboard b is placed under the tile a to be packaged) to the packaging station, and the small edge folding mechanism is located below the conveying channel of the conveying device 1, such as Figure 6 The wide edge folding mechanism 10 folds the wide edge 2b of the cardboard b upwards and surrounds the side of the tile a perpendicular to the conveying direction of the conveying device 1. At the same time, the driving mechanism drives the small edge pusher 2 upwards to approach the conveying channel, so that the small edge pusher 2 moves to the front or rear of the small edge 1b, such as Figure 7 Then, the folding driving mechanism drives the small edge pusher 2 to approach the small edge 1b of the paperboard b, and then the small edge pusher 2 bends the small edge 1b of the paperboard b toward the direction close to the tile a, so that the small edge 1b of the paperboard b is close to the side of the tile a parallel to the conveying direction of the conveying device 1, as shown in FIG. Figure 8 .

[0043] Next, the long edge folding mechanism (not shown in the figure, refer to the prior art) folds the long edge 3b of the cardboard b upward, wraps the small edge 1b and wraps it outside the side of the tile a parallel to the conveying direction of the conveying device 1, and uses other limiting mechanisms to press the folded wide edge 2b and long edge 3b, and then conveys it to other processing stations. The folding drive mechanism drives the small edge pusher 2 away from the small edge 1b, and the drive mechanism drives the entire small edge folding mechanism to reset.

[0044] Example 2

[0045] Different from the first embodiment, the driving mechanism in this embodiment is a vertical driving mechanism. In the working state, the vertical driving mechanism drives the small side pusher 2 vertically upward to approach the conveying channel.
