Description

Technical Field

[0001] This invention relates to the field of packaging box forming equipment technology, and in particular to a sash feeding device. Background Technology

[0002] The lining strip is a common part of high-end packaging boxes. Its function is to serve as the main support inside the packaging box after it is formed. In the production process of a fully open packaging box, the inner mold, lining strip, and top and bottom covers are first made into an inner box. Then, an outer paper is wrapped around the inner box to form an outer box. After wrapping, the outer box needs to be cut along the middle of the paper. The inner lining strip is left uncut and retained, and finally a fully open packaging box product is formed. The fully automated production solution is currently the development direction of the packaging box industry.

[0003] In existing technical solutions, inner molds are typically placed in rows in an inner mold storage bin. A pusher assembly within the inner mold feeding device pushes the inner molds in rows into an inner mold conveying device. Under the action of the inner mold conveying device, the inner molds move to the next station. The surrounding strips are placed in rows in an inclined surrounding strip feeding device. Under the action of the surrounding strip pusher assembly, one surrounding strip is pushed out at a time, completing a three-sided bonding action with the inner molds conveyed by the inner mold feeding device. Before forming, the surrounding strips are unfolded strips, divided into five segments according to the length-to-width ratio of a rectangular frame. After forming, the surrounding strips wrap around the inner mold, maintaining alignment at both ends. Due to the thickness limitations of the surrounding strips, pushing the surrounding strips using pushers often results in material leakage. Summary of the Invention

[0004] The main objective of this invention is to provide a material feeding device for the sheathing, which aims to solve the problem of material leakage and empty boxes caused by the use of push blades to push the sheathing in existing sheathing output methods.

[0014] Optionally, the adsorption device further includes a plurality of guide blocks, the plurality of guide blocks comprising:

[0015] Two side guide blocks are respectively located on the left and right sides of the adsorption station; and,

[0016] A central guide block is positioned above the adsorption station;

[0018] Optionally, the frame is further provided with a mounting plate extending vertically, the adsorption surface can be movably mounted on the mounting plate vertically, the two side guide blocks and the central guide block are fixedly mounted on the mounting plate, and the adsorption surface is provided with a sliding guide groove that cooperates with the central guide block.

[0019] Optionally, the transfer device includes:

[0022] Optionally, the conveyor belt is inclined at the front and upward at the back;

[0023] The pusher includes a square pusher and a round pusher, both of which are mounted on the conveyor belt and moved along the front-to-back direction by the conveyor belt. The square pusher is located in front of the round pusher and abuts against the rear end of the retaining strip.

Therefore, the strip feeding device improves the processing efficiency and the success rate of forming. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0039] In existing technical solutions, inner molds are typically placed in rows in an inner mold storage bin. A pusher assembly within the inner mold feeding device pushes the inner molds in rows into an inner mold conveying device. Under the action of the inner mold conveying device, the inner molds move to the next station. The surrounding strips are placed in rows in an inclined surrounding strip feeding device. Under the action of the surrounding strip pusher assembly, one surrounding strip is pushed out at a time, completing a three-sided bonding action with the inner molds conveyed by the inner mold feeding device. Before forming, the surrounding strips are unfolded strips, divided into five segments according to the length-to-width ratio of a rectangular frame. After forming, the surrounding strips wrap around the inner mold, maintaining alignment at both ends. Due to the thickness limitations of the surrounding strips, pushing the surrounding strips using pushers often results in material leakage.

[0040] To address the aforementioned problems, this invention proposes a sheath feeding device. Please refer to [link / reference]. Figures 1-5 This is an embodiment of the sheath feeding device. In this embodiment, the sheath feeding device includes a frame 1, a material transfer device, and an adsorption device. The frame 1 is provided with an arrangement station 11, an adsorption station 12, and a discharge station in sequence. The arrangement station 11 is used to arrange multiple sheaths 4 in a standing position along the front-back direction of the frame 1. The adsorption station 12 and the discharge station are arranged vertically at intervals. The material transfer device is installed on the frame 1 and is used to transfer multiple sheaths 4 from the arrangement station 11 to the adsorption station 12 in sequence. The adsorption device is installed on the frame 1 corresponding to the adsorption station 12 and is used to adsorb multiple sheaths 4 from the adsorption station 12 to the discharge station in sequence.

[0041] Typically, the shape of the retaining strip 4 is a flat, elongated strip. For example, when the retaining strip 4 is standing, its dimensions can be 20cm in length, 1cm in height, and 1mm in thickness. Therefore, if it is adsorbed from the thickness direction of the retaining strip 4, the retaining strip 4 can be obtained very easily. Compared with the existing method of pushing the retaining strip 4 with a pusher, the method of obtaining the retaining strip 4 by adsorption is more reliable and can significantly reduce the phenomenon of material leakage, thereby improving the reliability of the retaining strip 4 feeding process in the production line. Specifically, in the retaining strip feeding device of the present invention, the frame 1 is provided with an arrangement station 11, so that multiple retaining strips 4 are arranged one by one in a standing state along the front-back direction of the frame 1, and the multiple retaining strips 4 are pressed against each other. The front-back direction of the frame 1 is also the thickness direction of the retaining strip 4 when it is standing. Then, the material transfer device transfers the multiple retaining strips 4 located at the arrangement station 11 to the adsorption station 12. Conveyor belt 21 is typically used for conveying, which is not only simple in structure, low in cost, and highly reliable, but also facilitates control of the forward speed of the retaining strips 4. This is because the forward speed of the retaining strips 4 in their upright state should not be too fast, otherwise they will tilt, which is detrimental to their entry into subsequent processing steps after unloading. Furthermore, the adsorption device can sequentially adsorb the retaining strips 4 according to their arrangement, and then move them to the discharge station. During the movement, the upright position of the retaining strips 4 does not need to change, which is highly beneficial for subsequent processing. Please refer to [link / reference]. Figure 1 and Figure 3 ,in Figure 3 The device includes a forming device 5 installed on the lower layer of the bar feeding device. When the bar 4 enters the unloading station 13 while maintaining an upright position, the forming device 5 cooperates with the mold (not shown in the figure) that impacts the bar 4 in the rearward direction, so that the bar 4 is formed in the open forming groove formed by the forming device 5. Of course, in addition to the forming device 5, the device used for bar forming in this embodiment also includes other devices not shown in the figure. When the bar is initially formed, the bar is always in one-to-one correspondence with a single mold, and there will be no leakage of material, which improves the success rate of forming and thus improves the processing efficiency.

[0042] Furthermore, the adsorption device includes an adsorption surface 31 extending in the vertical direction. The length direction of the adsorption surface 31 is the left-right direction of the frame 1. The adsorption surface 31 has a movable stroke that switches between the adsorption station 12 and the discharge station. The adsorption surface 31 has multiple adsorption holes 311 arranged in the left-right direction. The multiple adsorption holes 311 are used to adsorb the surrounding strip 4 in the front-back direction of the frame.

[0043] In this embodiment, the opening positions of the multiple adsorption holes 311 can be arranged according to the outer contour of the strip 4, which can improve the firmness of adsorption. At the same time, the adsorption holes 311 are all opened at the lower end of the adsorption surface 31. In this way, when the adsorption surface 31 adsorbs the strip 4, the strip 4 is flush with the lower end surface of the adsorption surface 31. This is beneficial for the adsorption surface 31 to position the strip 4 when it enters the unloading station 13 downward and releases the strip 4, and at the same time, it is easy to keep the strip 4 in a stable standing position.

[0044] Furthermore, in this embodiment, the air pressure control of the multiple adsorption holes 311 is achieved by a vacuum pump located outside the feed device of this strip. The vacuum pump is connected to the air holes provided on the adsorption surface 311 through an air pipe, and the air holes are connected to each adsorption hole 311. Of course, the vacuum pump can also be replaced by other devices or equipment that can achieve the same function.

[0045] Furthermore, the feeding device for the sheathing also includes a platform 14 installed on the frame 1 at the corresponding workstations 11. The platform 14 extends along the horizontal plane so that the lower end face of each sheathing 4 remains horizontal when it enters the adsorption workstation 12. A gap 317 is provided between the front end face of the platform 14 and the adsorption surface 31. The gap 317 is used to allow the sheathing 4 adsorbed to the adsorption surface 31 to pass downwards, and the width of the gap 317 does not exceed the thickness of two sheathing 4.

[0046] To ensure that the retaining strip 4 remains upright and is adsorbed by the adsorption surface 31, the retaining strip feeding device also includes a platform 14. This allows the retaining strip 4 to return to its upright position even if it is tilted when fed into the adsorption station 12, after adjustment by the platform 14. Furthermore, a gap 317 is provided between the front end of the platform 14 and the adsorption surface 31. This gap 317 allows the retaining strip 4 to pass through when the adsorption surface 31, after adsorbing it, moves downwards to the unloading station 13. In this embodiment, the width of the gap 317 is set to be no more than the thickness of two retaining strips 4. This ensures that if the adsorption surface 31 receives two or more retaining strips 4, only one retaining strip 4 can be carried downwards, thus guaranteeing the reliability of the unloading process. Obviously, a more preferred approach is that the width of the gap 317 is exactly the thickness of one retaining strip 4.

[0047] Furthermore, a boss 312 protrudes from the upper end of the plurality of adsorption holes 311. The boss 312 has a lower end face for abutting the upper end of the wrapping strip 4. The length of the boss 312 protruding from the adsorption surface 31 does not exceed the thickness of the wrapping strip 4.

[0048] Please see Figure 4 The image shows a side view of the strips 4 arranged one by one at the arrangement station and when the strips 4 are adsorbed onto the adsorption surface 31. In this embodiment, in order to further ensure that the adsorption surface 31 only carries down one strip 4, a boss 312 is also provided on the adsorption surface 31. The boss 312 and the platform 14 work together to achieve this purpose. Obviously, the preferred method is that the height of the boss 312 is exactly the thickness of one strip 4.

[0049] Furthermore, multiple bosses 312 are spaced apart along the left and right directions, and multiple mounting slots 313 are opened on the adsorption surface 31 corresponding to the multiple bosses 312. Each boss 312 is detachably mounted to a mounting slot 313 by bolts.

[0050] Please see Figure 1 , Figure 4 and Figure 5 Multiple protrusions 312 are evenly provided along the length of the surrounding strip 4; in this embodiment, there are four protrusions, which further ensures the horizontal standing state of the surrounding strip 4. Figure 5This is a top view showing the mating of the adsorption surface 31 and the boss 312. The boss 312 is bolted to the mounting groove 313, facilitating adjustment of its protrusion height. To facilitate determining the height, a shim 319 can be added between the boss 312 and the adsorption surface 31. In this embodiment, D1 is the thickness of the boss 312, D2 is the thickness of the adsorption surface 31, D3 is the thickness of the shim, and D4 is the height of the boss 312. The dimension of D4 can be adjusted to be less than or equal to the thickness of one sheath 4. Obviously, the preferred method is that D1 = D2, and D4 is exactly the thickness of one sheath 4, because when processing the sheath 4, the sheath 4 itself can be directly used as the shim 319. When D1 = D2, the protruding height of D4 must be the thickness of the sheath itself. This structure makes setting the boss 312 both quick and precise.

[0051] Furthermore, the adsorption device also includes multiple guide blocks, including two side guide blocks 316 and a central guide block 314. The two side guide blocks 316 are respectively located on the left and right sides of the adsorption station 12, and the central guide block 314 is located above the adsorption station 12. The two side guide blocks 316 and the central guide block 314 form a guide channel, which is used to allow the retaining strip 4 to enter the adsorption station 12 from the platform 14.

[0052] In this embodiment, in order to further ensure that the bar 4 remains upright when it is adsorbed, multiple guide blocks are provided to guide the bar 4 from the left, right and top sides, and limit and guide it according to the outer contour of the bar 4.

[0053] Further, please refer to Figure 1 The platform 14 is also equipped with adsorption guide blocks 121 on the left and right sides, which also serve to limit and guide the left and right sides of the surrounding strip 4.

[0054] Furthermore, the frame 1 is also provided with a mounting plate 15 extending vertically, the adsorption surface 31 can be movably mounted on the mounting plate 15 vertically, the two side guide blocks 316 and the middle guide block 314 are fixedly mounted on the mounting plate 15, and the adsorption surface 31 is provided with a sliding guide groove 315 that cooperates with the middle guide block 314.

[0055] In this embodiment, the adsorption surface 31 is movable in the vertical direction and is driven by the linear cylinder 318. In order to avoid too many parts on the adsorption surface 31, which would increase the weight and make it difficult to control the linear cylinder 318, the adsorption surface 31 is relatively movable with the two side guide blocks 316 and the middle guide block 314. This can save the driving force of the linear cylinder 318 and improve the economy of the device. At the same time, it can also reduce the occupation of the lower space of the device when the adsorption surface 31 moves downward, which is beneficial to the installation and arrangement of the molding device 5 and other molding and processing molds.

[0056] Furthermore, the material transfer device includes a conveyor belt 21 and a pusher. The conveyor belt 21 extends in the front-to-back direction and the front end of the conveyor belt 21 is connected to the platform 14. The pusher is movable in the front-to-back direction and is used to support the rear end strip 4 at the arrangement station 11.

[0057] Please see Figure 1 This device uses a conveyor belt 21 to move multiple strips 4 from the arrangement station 11 to the adsorption station 12. In order to ensure the stability of the posture of the multiple strips 4, a pusher is provided at the rear end of the multiple strips 4 for support. Of course, the pusher can also play a pushing role, working together with the conveyor belt 21 to drive the multiple strips 4 forward.

[0058] Furthermore, the conveyor belt 21 is inclined at the front and high at the back. The pushing component includes a square push rod 22 and a round push rod 23. Both the square push rod 22 and the round push rod 23 are mounted on the conveyor belt 21 and are driven by the conveyor belt 21 to move in the front-back direction. The square push rod 22 is located in front of the round push rod 23 and abuts against the rear end strip 4. The round push rod 23 can be rolled along the left-right axis to push the square push rod 22.

[0059] Please see Figure 1 The pusher includes a square push rod 22 and a round push rod 23. The square push rod 22 serves as a support, while the round push rod 23 can move forward with the conveyor belt 21, thereby pushing the square push rod 22. In order to facilitate the forward rolling of the round push rod 23, the conveyor belt 21 is inclined at the front and high at the back, which simplifies the structure of the device and saves costs.

[0060] Furthermore, the material transfer device also includes two guide side plates 24, which are respectively disposed on the left and right sides of the conveyor belt 21 to limit the left and right sides when the conveyor belt 21 transfers multiple strips 4, so as to prevent the strips 4 from tilting when moving forward.

[0061] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
