The folding box can be unfolded to form a paper box for packaging through the folding structure, and can also be folded and closed into a flat plate for easy storage and transportation. At present, the main structure of a folding box includes a main board and two side boards (i.e., side walls). When unfolded, the main board and the side walls cooperate to form a paper box; wherein the main board is usually a skin structure, the skin structure has multiple pieces of paperboard in the middle and face paper pasted on the front and back of these middle paperboards, the outer mounting equipment (including the main conveyor belt for skin mounting paper) mounts the face paper on the front of the paperboard, and the inner mounting equipment (including the main conveyor belt for skin mounting paper) mounts the face paper on the back of the paperboard; wherein the side wall is a folding board (i.e., folding paperboard), such as a three-piece paperboard, a five-piece paperboard, etc. (usually one side of paper is also pasted on the front and back), for example, the side wall of the folding box produced in cooperation with the CN112440516A folding board cover machine, etc., the middle section area of the side wall is thicker, and the two side areas of the side wall are thinner; after the main board and the side wall are respectively produced, they are assembled and connected manually, and the edge of the middle section area of the side wall is glued and connected to the main board (the outer surface of its face paper), and the manual assembly and connection is inefficient and of poor quality.

Chinese patent document CN219947423U discloses a folding box side wall assembly device, wherein a first side wall feeding device has a first output end, a second side wall feeding device has a second output end, a first side wall conveyor belt has a first input station and a first delivery station, the first output end is connected with the first input station, the second side wall conveyor belt has a second input station and a second delivery station, the second output end is connected with the second input station, and the first delivery station and the second delivery station are respectively connected with the side wall assembly station of the shell paper mounting main conveyor belt through a transfer robot.

Although this structure uses mechanized operation to replace manual labor and increase efficiency, its side wall conveyor belt and the main conveyor belt are still orthogonal. The connection structure occupies too much space. Although the patent also mentions a parallel assembly method, its specification mentions that there is a situation in which the first side wall conveyor belt or the second side wall conveyor belt is sandwiched in the middle, which is not conducive to assembly and operation. The article does not solve the problem and does not provide a specific description of the parallel assembly method.

Utility Model Content

In summary, in order to overcome the deficiencies of the prior art, the utility model provides a space-saving wing assembly device for a folding box assembly machine.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a side wing assembly device of a folding box assembly machine, comprising a first frame and a manipulator, and also comprising a side wing feeding device, the side wing feeding device and its conveying direction are both arranged parallel to the side of the main conveyor belt, the side wing feeding device is provided with two, the two side wing feeding devices are arranged opposite to each other, the side wing feeding device comprises a side wing conveying mechanism and a side wing feeding mechanism, the side wing conveying mechanism comprises a conveying assembly and a conveying block, a conveying surface is provided on the top of the first frame, and the conveying assembly drives the conveying block to reciprocate on the conveying surface toward the direction of the other side wing feeding device.

With such an arrangement, when in use, the side wing is first stacked on the side wing feeding mechanism, and then the side wing feeding mechanism will convey a side wing toward the conveying surface on the top of the first frame, and then the conveying assembly will carry the conveying block on the conveying surface to push the side wing to move it toward the direction of the other side wing feeding device until it reaches the appropriate position and stops, and then the robot will suck up the side wing and move it to the main conveyor belt for the next steps. The two side wing feeding devices are arranged opposite to each other on both sides, and the position between the two is the correct position. After the parallel arrangement, the structure is compact and the space occupied is small. The push block is used to drag the side wing without slipping, the position push is accurate, and the transmission position error is not easy to occur.

Furthermore, the conveying surface is provided with a conveying trough, the side wing conveying mechanism is located below the conveying surface, the conveying block is located in the conveying trough, and the conveying block is provided with a pushing block located above the conveying surface.

With such arrangement, the side wing conveying mechanism is located as a whole below the conveying surface, that is, inside the first frame, which saves more space. A push block extends from the inside to the outside of the conveying block at the position of the conveying groove, and the push block pushes the side wing on the conveying surface. The volume of the upper part of the conveying surface is small, and the impact on the conveying process is small. After the conveying groove is set, the contact area between the side wing is reduced, the friction between the two is reduced, and the conveying process is smoother.

Furthermore, the conveying assembly includes a driving motor, a conveyor belt and two conveying wheels, the conveying wheels are arranged on the first frame, the conveyor belt is mounted on the two conveying wheels, the driving motor drives one of the conveying wheels to rotate, and the conveying block is fixedly connected to the conveyor belt.

The structure is simple, the drive motor can be a servo motor, and the conveyor belt and conveyor wheels can be synchronous belts and synchronous wheels, so the movement is more precise.

Furthermore, a protrusion is provided on the side of the conveying block facing the other side wing feeding device, the top surface of the protrusion is not higher than the conveying surface, and the top surface of the protrusion is tilted downward toward the direction of the other side wing feeding device.

With this arrangement, the convex head will support the side wings that fall on it in the conveying trough, preventing the side wings from sinking in the conveying trough, making it more stable, and the top of the convex head is tilted into a cone, so that it will be inserted under the side wings when pushed without hitting them.

Furthermore, two positioning bars are provided on the top of the first frame, the conveying surface is located at the top surface of the positioning bars, the cross-section of the positioning bars is L-shaped, the two positioning bars are arranged opposite to each other on the first frame, and the cross bars of the two positioning bars are arranged facing each other.

With this arrangement, the top inner edge lines of the two positioning strips will correspond to the positions of the two folds of the side wings, so that when the side wings fall on the positioning strips, they can play a positioning guide role. When the robot presses down, the thick plate in the middle of the side wing will be pressed down, and the thick plate part in the middle of the side wing will slide toward between the two L-shaped positioning strips to correct the position. Then the robot sucks up the side wing, so that the position will not shift, and the L-shaped cross plate can also play a supporting role to prevent the side wings from being too concave, and the gap between the two positioning strips will form a conveying trough, without the need to process long troughs, and the processing is convenient.

Furthermore, the side wing conveying mechanism also includes a telescopic machine and a lifting frame. There are two push blocks, and the two push blocks are arranged in the conveying direction of the side wing feeding device. The push blocks are arranged on the lifting frame, and the telescopic machine controls the lifting frame to vertically lift and lower on the conveying block.

With this arrangement, the side wing conveying mechanism has two conveying stations. The side wing feeding mechanism first sends one side wing to the position of the push block on the outside, and then the conveying component operates to move the side wing to the half-way position, and then the telescopic machine operates to lower the lifting frame, so that the push block drops down, and the conveying block returns to its original position. The telescopic machine raises the lifting frame again. At this time, the push block of the second station will reach the edge of the first side wing, and then the side wing feeding mechanism will put down the second side wing, and the conveying component will operate again to move the side wing to the half-way position, and the side wing of the second station will move to the position where the robot picks up the material. This process is repeated to convey the side wing with double efficiency.

Furthermore, the side feeding mechanism includes a third frame, a feeding motor, a feeding conveyor belt and two feeding rollers. The third frame is provided with a feeding station. The feeding conveyor belt is located in the feeding station. The feeding conveyor belt is sleeved on the two feeding rollers. The feeding rollers are connected to the third frame. The feeding motor drives one of the feeding rollers to rotate. The feeding station is provided with a feeding outlet.

With this arrangement, the side wing pile is stacked at the feeding station. During feeding, the feeding motor is operated to drive the feeding conveyor belt to rotate under the feeding station. The friction force will move the side wing at the bottom toward the feeding outlet. The height of the feeding outlet can only be passed by one side wing, so that one side wing will be sent from the outlet to the conveying surface and moved by the side wing conveying mechanism. The structure is simple, and the third frame can be used to facilitate operations such as component assembly and replenishment of materials during operation.

Furthermore, the side feeding mechanism is connected to the first frame above it, the feeding conveyor belt is arranged parallel to the main conveyor belt, the feeding outlet is arranged to face away from the other side feeding device, and the side of the third frame where the feeding outlet is provided is arranged to be tilted downward.

With this arrangement, the side wing feeding mechanism is above the first frame and its feeding conveyor belt is parallel to the main conveyor belt, that is, parallel to the conveying direction of the side wall feeding device. It occupies a small horizontal space and saves more space. After its inclined arrangement, the side wing pile will fall on the third frame. The retaining wall is above the feeding outlet of the third frame. When the side wing falls at this position, it has two-sided support, which is more stable, and the side wing push also has an additional downward force.

Furthermore, a baffle is provided at a position on one side of the first frame corresponding to the feeding outlet, and a distance between the baffle and the third frame is greater than a length of a side wing.

With such arrangement, when the side wing is sent out from the third frame, it will hit the baffle and be stopped, thus preventing it from sliding too far due to inertia. The distance between the two also ensures that the side wing can fall between the two.

Furthermore, a positioning plate hinged to the feeding outlet is provided on a side of the third frame body facing away from the feeding outlet, and the positioning plate is located above the third frame body.

With such arrangement, the positioning plate will support the bottom of the wing pile from one side, thus achieving a positioning effect thereon and making it more stable.
