Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to paper stacking and bundling equipment. Background Art

[0002] During the baling and packaging process of corrugated cardboard stacks, the corners of the corrugated cardboard stacks are often damaged by the PET tape (engineering plastic tape). In severe cases, this can cause the upper cardboard to be scrapped. Therefore, it is necessary to add a layer of paper corner protectors to the corners of the paper stack to prevent the corrugated cardboard stack from being damaged by direct contact with the PET tape. Currently, when baling corrugated cardboard stacks, the paper corner protectors are mostly placed manually, which has low baling efficiency and high production costs. Some baling equipment that uses automatic paper corner protector placement directly places the 90° formed paper corner protectors on the edge of the paper stack. The shaped paper corner protectors are difficult to pick up and place, and the paper corner protectors are easily damaged, deformed, or dropped during the process of being moved by the baling equipment. The baling equipment has poor reliability and is inconvenient to use. Utility Model Content

[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] like Figures 1 to 5 As shown, this embodiment first provides a paper stack bundling device, which includes a bundling device 1 and two sets of corner protector adding devices 2, for adding paper corner protectors to and bundling a bundle 200. The bundle 200 includes but is not limited to a corrugated paper stack.

[0033] The baling device 1 includes a frame assembly 11, a belt feed assembly 12, and a baling assembly 13. The frame assembly 11 includes a fixed frame 111 and a lifting platform 112. The fixed frame 111 has a baling position. The lifting platform 112 is connected to the fixed frame 111 and can reciprocate along the height direction of the fixed frame 111. The lifting platform 112 is located above the baling position. Two sets of corner protector adding devices 2 are both provided on the lifting platform 112, and are located on either side of the baling position. This allows paper corner protectors to be added to both sides of the package 200, thereby improving efficiency. The lifting platform 112 can adjust the height of the corner protector adding devices 2 according to the height of the package 200 to meet the needs of different packages 200 and improve applicability.

[0034] The corner protector adding device 2 includes a pushing assembly 21 and a storage box 22 for accommodating multiple sheets of protective paper 100. The pushing assembly 21 is used to push the protective paper 100 onto the bundled object 200 located at the bundling position. The multiple sheets of protective paper 100 are all flat, and the storage box 22 is relatively small, thus reducing space usage. Furthermore, the flat protective paper 100 is easily pushed by the pushing assembly 21, preventing damage and deformation by the pushing assembly 21 during movement, making it easy to use and improving the reliability of the paper stack bundling device. The belt feeding assembly 12 is used to feed the strapping tape so that the strapping tape is wrapped around the bundled object 200 and wound around the protective paper 100. The bundling assembly 13 is located on a lifting platform 112 and is used to tighten and bind the strapping tape so that the protective paper 100 is bent to form a paper corner protector. The tightening force of the strapping tape bends the flat protective paper 100 to form the paper corner protector, thereby reducing manual operation, improving bundling efficiency, and lowering production costs.

[0035] The protective paper 100 can be processed on-site using scraps generated during the production of the packaging material 200, and can be cut into multiple sheets of protective paper 100 according to required sizes, thereby reducing production costs and improving economic benefits.

[0036] The corner protector adding device 2 has a first pushing position and a second pushing position, both located outside the storage box 22. The pushing assembly 21 pushes the protective paper 100 to the first and second pushing positions, respectively. When the protective paper 100 is in the first pushing position, it is positioned next to the bale 200. When the protective paper 100 is in the second pushing position, part of the protective paper 100 adheres to the top surface of the bale 200 and part of the protective paper 100 adheres to the side of the bale 200. In this way, when the strapping assembly 13 tightens and ties the strapping tape, the part of the protective paper 100 adjacent to the bale 200 is bent and adheres to the side of the bale 200, forming a 90-degree bend in the protective paper 100.

[0037] In order to increase the uniformity of force applied to the protective paper 100 during the bending process, and the uniformity of the protection provided by the paper corner protectors to the two surfaces of the packaged object 200, when the protective paper 100 is located at the second pushing position, along the width direction of the protective paper 100, half of the protective paper 100 is in contact with the upper surface of the packaged object 200 and the other half is arranged on the side of the packaged object 200, that is, the center line of the protective paper 100 along the length direction coincides with the edge line of the packaged object 200.

[0038] In one embodiment, the pushing assembly 21 includes a longitudinal pushing mechanism 211 and a transverse pushing mechanism 212. The longitudinal pushing mechanism 211 can be connected to the storage box 22 and can be reciprocated along a first direction to push the protective paper 100 in the storage box 22 to the first pushing position. The transverse pushing mechanism 212 is used to reciprocate along a second direction to move the protective paper 100 in the first pushing position to the second pushing position. The first direction is perpendicular to the second direction, and the first direction is perpendicular to the wrapping direction of the strapping tape, that is, the first direction is the same as the incoming direction of the packaged object 200, and the second direction is parallel to the wrapping direction of the strapping tape. The length direction of the protective paper 100 extends along the first direction, and the length that can wrap around the edge of the packaged object 200 is longer; the width of the protective paper 100 extends along the second direction.

[0039] The moving position of the protective paper 100 relative to the packaging object 200 is decomposed into a first pushing position and a second pushing position. The action of the pushing component 21 is completed by decomposing the longitudinal pushing mechanism 211 and the transverse pushing mechanism 212 into two actions, which can avoid interference between the pushing component 21 and the packaging belt.

[0040] The output end of the longitudinal pushing mechanism 211 can employ any of a suction cup, a pneumatic clamp, or a spring clamp. In one embodiment, the longitudinal pushing mechanism 211 comprises a clamp and a longitudinal drive. The clamp is connected to the output end of the longitudinal drive. The clamp is configured to grip the protective paper 100 at the first pushing position, and the longitudinal drive drives the clamp to reciprocate in a second direction. The clamp grips the protective paper 100 along its thickness, providing a more stable grip and preventing the protective paper 100 from falling during movement.

[0041] The longitudinal drive member and the transverse drive member of the transverse pushing mechanism 212 can be any one or a combination of a linear cylinder, a hydraulic cylinder, a linear motor, a rack and pinion transmission mechanism, or a screw pair transmission mechanism. Preferably, the longitudinal drive member and the transverse pushing mechanism 212 are rodless cylinders, and the stroke of the rodless cylinder can be set and adjusted as needed. This ensures that the pushing stroke of the longitudinal pushing mechanism 211 and the transverse pushing mechanism 212 is not affected by the relative position misalignment between the package 200 and the lifting platform 112, thereby ensuring the accuracy of the relative position of the protective paper 100 and the package 200. The transverse pushing mechanism 212 is also equipped with a three-position, center-sealed, five-way solenoid valve, which allows it to stop at any position and adjust the relative position between the protective paper 100 and the package 200 according to the bundling requirements.

[0042] In one embodiment, the pushing assembly 21 further includes a first in-place detection member and a second in-place detection member (not shown). The first in-place detection member is configured to detect the relative position of the protective paper 100 and the first pushing position, and the second in-place detection member is configured to detect the relative position of the protective paper 100 and the second pushing position. The first in-place detection member is communicatively connected to the longitudinal pushing mechanism 211 and controls the pushing stroke of the longitudinal pushing mechanism 211 based on the detection result of the first in-place detection member. The second in-place detection member is communicatively connected to the transverse pushing mechanism 212 and controls the pushing stroke of the transverse pushing mechanism 212 based on the detection result of the second in-place detection member. The first in-place detection member can be any one or a combination of a mirror reflection sensor, a diffuse reflection sensor, a distance sensor, or a proximity switch, and this embodiment does not specifically limit this. The second in-place detection member can be a diffuse reflection sensor and can detect the edge of the package 200. Based on the position of the package 200 and the widthwise dimension of the protective paper 100, the second in-place detection member can control the delay time so that the middle area of the widthwise direction of the protective paper 100 is directly above the edge of the package 200.

[0043] In one embodiment, a discharge port is provided at the lower portion of the side panel of the storage box 22. Figure 3 and Figure 4 As shown, the bottom plate of the storage box 22 is provided with a guide groove 221, which is connected to the discharge port. Multiple sheets of protective paper 100 are stacked in sequence along the height direction of the storage box 22. The longitudinal pushing mechanism 211 includes a push plate 2111, which is slidably arranged in the guide groove 221, and the top of the push plate 2111 is not higher than the upper surface of the bottom layer of protective paper 100. The push plate 2111 moves along the guide groove 221 to push the protective paper 100 through the discharge port and move to the first pushing position. When the push plate 2111 pushes the bottom layer of protective paper 100, the remaining multiple sheets of protective paper 100 fall under the action of gravity and land on the bottom plate of the storage box 22. Each time the push plate 2111 pushes the bottom layer of protective paper 100, the process repeats over and over again. In this way, the push plate 2111 is always located at the same height direction. The push plate 2111 only moves back and forth in one direction, and does not need to perform lifting movement, thereby simplifying the structure. Exemplarily, the top of the push plate 2111 is 2 mm lower than the upper surface of the bottom protective paper 100 .

[0044] The push plate 2111 needs to form a reciprocating movement to perform multiple pushes. The pushing component 21 is also provided with an avoidance mechanism 213. The avoidance mechanism 213 is connected to the push plate 2111. When the bottom protective paper 100 all passes through the discharge port, the avoidance mechanism 213 drives the push plate 2111 away from the guide groove 221 to avoid the protective paper 100 falling along the height direction of the storage box 22.

[0045] The push plate 2111 has multiple avoidance directions, such as avoiding below the guide groove 221 or avoiding to the side of the guide groove 221. Accordingly, the avoidance mechanism 213 has multiple motion modes. Exemplarily, the avoidance mechanism 213 can be any one of a swing cylinder, a pneumatic motor, a hydraulic motor, and a servo motor, or a combination thereof. Exemplarily, the avoidance mechanism 213 can drive the push plate 2111 to rotate 90° along the length of the guide groove 221. After the push plate 2111 rotates 90°, it changes from a vertical state to a horizontal state and moves away from the storage box 22, avoiding the falling protective paper 100 and preventing the push plate 2111 from interfering with the falling protective paper 100 when returning to its initial position.

[0046] To prevent the protective paper 100 from getting stuck in the storage box 22, the corner protector adding device 2 further includes a pressure plate 23. The pressure plate 23 is disposed in the storage box 22 and presses against the tops of the plurality of protective paper 100. The pressure plate 23 is configured to press down the plurality of protective paper 100 by its own weight. The pressure plate 23 can be made of a polyurethane plate to prevent deformation.

[0047] To ensure continuous addition of paper corner protectors, the corner protector adding device 2 is equipped with an out-of-stock detection sensor within the storage box 22. This sensor detects the presence of protective paper 100 within the storage box 22 and issues an alarm when the protective paper 100 is exhausted, prompting the operator to promptly add protective paper 100 to the storage box 22 to ensure continuous production. The out-of-stock detection sensor can be any one of a mirror reflection sensor, a diffuse reflection sensor, a distance sensor, a proximity switch, and a weighing sensor, or a combination thereof, and is not specifically limited in this embodiment.

[0048] In one embodiment, the packaged object 200 includes a paper stack 201 and a tray 202 for supporting the paper stack 201. Figure 2 As shown, the tray 202 is provided with guide notches 2021 extending through both ends. The bundling device 1 further comprises a piercing assembly 14, which comprises a guide rail frame 141 and a piercing member 142. Figure 5 As shown. The piercing member 142 is connected to the guide rail frame 141 so as to be reciprocally movable along the length direction of the guide rail frame 141. The piercing member 142 has a first belt threading slot 1421. The piercing member 142 can be inserted into the guide notch 2021 so that the first belt threading slot 1421 extends below the paper stack 201. The first belt threading slot 1421 is used to thread the strapping tape so that the strapping tape wraps around the bottom of the paper stack 201. When the packaged object 200 is in the bundling position, the piercing member 142 extends out of the guide rail frame 141 along the length direction and passes through the guide notch 2021. The strapping tape extends within the first belt threading slot 1421 of the piercing member 142, thereby wrapping around the bottom of the paper stack 201.

[0049] The fixed frame 111 consists of a left column and a right column. Both columns are equipped with a lifting drive mechanism and a guide mechanism for the lifting platform 112. The lifting drive mechanism drives the lifting platform 112 up and down along the guide mechanism. The left column and the right column are respectively provided with a second belt threading slot 1111 and a third belt threading slot 1112 extending along the height of the fixed frame 111. The lifting platform 112 is provided with a fourth belt threading slot extending horizontally. The fourth belt threading slot is parallel to the first belt threading slot 1421. The first belt threading slot 1421, the second belt threading slot 1111, the third belt threading slot 1112, and the fourth belt threading slot are interconnected to form a closed loop.

[0050] The fixed frame 111 and the lifting platform 112 form a gantry structure, facilitating the formation of a bundling station below the lifting platform 112. The bundling device 1 includes a reel truck and a tape feed guide wheel assembly 15 located above the reel truck. The reel truck winds unused strapping tape. The tape feed guide wheel assembly 15, located between the reel truck and the tape feed assembly 12, feeds the free end of the strapping tape from the reel truck to the tape feed assembly 12. The tape feed assembly 12 is mounted on the lifting platform 112 and is capable of pressing against the upper surface of the paper stack 201, thereby compacting the paper stack 201. The tape feed assembly 12 guides the strapping tape provided by the reel truck, allowing the free end of the strapping tape to be sequentially threaded through the fourth tape threading slot, the third tape threading slot 1112, the first tape threading slot 1421, and the second tape threading slot 1111, thereby wrapping around the package 200 and forming a wrap around the package 200. Then, the strapping assembly 13 tightens the strapping tape so that the strapping tape passes through the first strapping slot 1421, the second strapping slot 1111, the third strapping slot 1112, and the fourth strapping slot and is tightly wrapped around the package 200. The strapping tape can be passed in a clockwise or counterclockwise direction, which is not specifically limited in this embodiment.

[0051] The strapping assembly 13 can cut the tightened strapping tape and weld the two ends to complete the strapping operation. The specific structure and working principle of the strapping assembly 12, strapping assembly 13, piercing assembly 14, and strapping guide wheel assembly 15 can be set with reference to the existing technology and are not limited to this embodiment.

[0052] To ensure that the corner protector adding device 2 does not activate until the bale 200 reaches the baling position, the paper stack baling device further includes a third position detection element. This third position detection element is configured to detect the relative position of the bale 200 and the baling position and is communicatively connected to the corner protector adding device 2. The corner protector adding device 2 will not begin adding the protective paper 100 until the third position detection element detects that the bale 200 has reached the baling position.

[0053] The baling device 1 can bundle the package 200 with one strapping belt at a time. When the package 200 requires two strapping belts, the paper stack baling equipment can be provided with two sets of strapping components 12, two sets of strapping components 13, two sets of piercing components 14 and two sets of strapping guide wheel components 15, which are respectively located on both sides of the frame component 11. The two strapping belts are bundled with two strapping belts at the same time. The two strapping belts are arranged in parallel and at intervals, and are bundled together at both ends of the same protective paper 100 along the length direction of the protective paper 100. The bundling of the package 200 is more reliable and not easy to loosen.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
