Description

Technical Field

[0001] This utility model pertains to post-press equipment, and more specifically, relates to a vacuum suction cup type separation and conveying device, which is mainly used in the in-line configuration of liner bonding machines. Furthermore, this utility model also relates to a liner bonding machine that includes such a vacuum suction cup type separation and conveying device. Background Technology

[0002] Currently, the non-stop cardboard conveying device of the lining bonding machine mainly adopts the push-type cardboard separation technology. The key structural feature of this technology is the addition of a small step on the pusher. The height of this small step needs to be less than the thickness of a single sheet of paper, thus ensuring that only one sheet is pushed during separation. However, during the process of pushing the paper, friction exists between the pushed-out paper and the material pile above. If the paper or cardboard is thin or bent, the cardboard can easily deform during operation, making it easy for it to escape the small step of the pusher. Therefore, this push-type separation structure requires that the cardboard placed in the hopper be flat and free of bends. If the cardboard is bent, the separation structure will malfunction. Therefore, during manual feeding, the flatness of the cardboard needs to be checked. If it is not flat, it needs to be manually flattened before being placed in the hopper.

[0003] This push-down paperboard separation technology has a simple structure and provides stable separation when the paperboard is not very thin, but it is only suitable for stand-alone operation. However, market demands are changing, and many liner gluing machines now require inline production to reduce manual labor and lower costs. In this mode, the paper products fed from the previous process typically need to be glued before being conveyed and falling into the hopper of the liner gluing machine. Because the glue dries continuously during paper transport, it causes the paperboard to bend and deform, leading to separation failures and significantly reducing inline efficiency.

[0004] Therefore, there is an urgent need to provide an improved vacuum suction cup separation and conveying device that can overcome one or more of the disadvantages of the prior art. Utility Model Content

[0005] In view of the above-mentioned problems of the prior art, the purpose of this utility model is to provide an improved vacuum suction cup type separation and conveying device, which can convey sheet materials in the lining machine and can greatly improve the stability and reliability of the lining machine line.

[0006] According to one aspect of the present invention, a vacuum suction cup type separation and conveying device is provided, which can be used in a lining bonding machine for conveying sheets. The vacuum suction cup type separation and conveying device may include: a power system, which may include a drive device and a guide device attached to the drive device, wherein the drive device can reciprocate between a first position and a second position; a separation control device, which may be fixed to the guide device; and a suction cup device, which is carried by the separation control device and includes a suction cup, wherein the separation control device causes the suction cup device to pivot relative to the guide device, and the suction cup can selectively pick up or release sheets to achieve sheet conveying.

[0007] This invention relates to a vacuum suction cup-type separating and conveying device that uses a vacuum suction cup to pick up and separate the bottom sheet of a stack of sheets (such as cardboard) in a hopper, and then picks it up and conveys it forward. This structure allows for low friction during the conveying process, and the separation process is not affected by the flatness of the sheet, making it more stable and reliable, and greatly improving the efficiency of line production.

[0008] According to the above aspects of the present invention, preferably, the separation control device includes a first pivoting mechanism, which is pivotally supported by the guide device and causes the suction cup device to change between a conveying position and an avoidance position relative to the guide device.

[0015] This mechanism allows for more precise and reliable control of the suction cup device's movement to achieve the desired transport and pick-up operations.

[0017] This arrangement allows for quick installation of the suction cups and enables the number and spacing of the suction cups to be adjusted according to the size of the sheet, thus achieving more reliable conveying.

[0018] According to the above aspects of the present invention, preferably, the suction cup device may further include: a mounting base, which may include a fixed upper base, a fixed lower base, and a fastening device, wherein the fixed upper base and the fixed lower base are hinged together by a pin, and a mounting groove is provided on the fixed upper base; and a suction base, which is fixed on the fixed upper base and connected to a feed line, wherein the suction cup is connected to the suction base to generate a vacuum in the suction cup for sucking up or releasing the sheet.

[0019] This arrangement further facilitates the rapid installation of the suction cup device and enables the creation of a vacuum within the suction cup as needed to pick up or release sheets.

[0020] According to the above aspects of this utility model, preferably, it may further include a control device, which is configured such that as the guide device is driven to move between a first position and a second position, the suction cup picks up the sheet at the first position and releases the sheet at the second position. This enables automated and reliable sheet feeding, improving the efficiency of inline production.

[0083] It should be understood that, unless explicitly stated otherwise, the present invention may employ various alternative orientations and sequences of steps. It should also be understood that the specific devices shown in the drawings and description are merely exemplary embodiments of the inventive concept disclosed and defined herein. Therefore, unless expressly stated otherwise, the specific orientations, directions, or other features involved in the various disclosed embodiments should not be considered limiting.

[0084] Figure 1 This is a schematic perspective view of a vacuum suction cup type separating and conveying device 100 according to a non-limiting embodiment of the present invention. The vacuum suction cup type separating and conveying device 100 can be used in a liner bonding machine for conveying sheet material 200.

[0085] As used herein, the term "sheet" can refer to thin, sheet-like products such as paper, cardboard, or plastic sheets, and these sheets can be stacked together to form a sheet stack, such as a cardboard stack. Additionally, as used herein, the term "connection" can refer to the continuous automated operation of sheets, for example, where sheets can be automatically fed into a hopper by equipment and automatically transported from the hopper to the next process step without additional manual intervention.

[0086] like Figure 1 As shown and as a non-limiting embodiment, the vacuum suction cup type separation and conveying device 100 may mainly include: a power system 10, a separation control device 20, a suction cup device 30, etc.

[0087] Figure 2 This is a schematic perspective view of the power system 10 of the vacuum suction cup type separation and conveying device 100 according to a non-limiting embodiment of the present invention.

[0088] As shown in the figure, the power system 10 may include a drive unit 11 and a guide unit 12 attached to the drive unit. The drive unit 11 may be used to reciprocate the guide unit 12 between a first position and a second position. As an example, the first position may be an initial position where the vacuum suction cup type separation conveyor 100 can pick up the sheet 200, while the second position may be the desired position for releasing the sheet 200. Figure 2 In the example shown, the first position can be located on the left side of the figure, while the second position can be located on the right side of the figure.

[0089] According to the present invention, the power system 10 can be used to realize reciprocating linear motion between a first position and a second position. Therefore, any type of power mechanism known in the art can be used, such as a linear motor, a pneumatic or hydraulic linear actuator, or a mechanism for converting the rotational motion of a rotary motor into linear motion.

[0090] As a non-limiting embodiment and as Figure 1 and 2 As shown, the drive device 11 can be a cam drive device and can mainly include a cam assembly 111, a swing device 112, a tensioning device 113, and a connecting rod assembly 114, etc.

[0091] The cam assembly 111 may include a rotating shaft 111A and a cam plate 111B fixed to the rotating shaft 111A. The rotating shaft 111A may be pivotally supported by a frame 10A and drivenly connected to a motor (not shown), for example via a gear drive or belt drive mechanism, to rotate with the output shaft of the motor. The cam plate 111B may be fixed to the rotating shaft 111A and rotate with the rotating shaft 111A. For example, the cam plate 111B may be integrally formed with the rotating shaft 111A or fixed together via a spline connection, etc.

[0092] In the embodiment shown in the accompanying drawings, two cam plates 111B can be provided and can be symmetrically arranged on the rotation axis 111A. The cam plates 111B can be configured with a profile according to the desired motion trajectory, for example, having a smooth profile that is approximately oval.

[0093] The swing device 112 may mainly include a swing shaft 112A, a swing seat 112B, and a cam roller 112C.

[0094] The swing shaft 112A can be pivotally supported by the frame 10A. For example, a bushing such as a copper bushing can be fitted on the swing shaft 112A to reduce rotational friction.

[0095] The swing seat 112B can be fixed to the swing shaft 112A, allowing the swing seat 112B to pivotally swing along the swing shaft 112A. In the embodiment shown in the figures, the swing seat 112B can have a generally triangular plate-like shape, and is fixed to the swing shaft 112A at one corner of the triangle. In the embodiment shown in the figures, two swing seats 112B can be provided, and can be symmetrically arranged on the swing shaft 112A, corresponding to the positions of the two cam plates 111B.

[0096] The cam roller 112C can be pivotally fixed to the swing seat 112B. For example, the center of the cam roller 112C can be pivotally fixed to the swing seat 112B, allowing the cam roller 112C to rotate freely. Additionally, the cam roller 112C can cooperate with the cam plate 111B to drive the swing seat 112B to oscillate around the swing axis 112A. For example, the circumferential edge of the cam roller 112C can abut against the circumferential edge of the cam plate 111B, so that as the cam roller 112C rotates, the swing seat 112B is pushed forward (oscillates to the left in the figure) or moved backward (returns to the right in the figure). Similarly, as shown, two cam rollers 112C can be provided.

[0097] To enable the return movement of the swing seat 112B, a tensioning device 113 can be provided. The tensioning device 113 can be fixed to the swing seat 112B and bias the cam roller 112C fixed to the swing seat 112B against the cam plate 111B.

[0098] As shown in the figure and as a non-limiting example, the tensioning device 113 may include a spring 113A, the two ends of which are pivotally fixed to the swing seat 112B and the frame 10A, respectively. Specifically, the first end of the spring 113A (the left end shown in the figure) may be attached to the swing seat 112B via the extension shaft 113B, while the second end of the spring 113A (the right end shown in the figure) may be attached to the frame 10A via the small fixing seat 113C.

[0099] Preferably, spring seats 113D can be provided at both ends of spring 113A, and the tensioning device 113 can include bushings, such as oil-impregnated sleeves. The oil-impregnated sleeves can be respectively fitted onto the small shafts of the extending shaft 113B and the small fixed seat 113C, allowing free rotation relative to the extending shaft 113B and the small shafts. In this way, the spring seats 113D at both ends of each spring 113A can be fitted onto the oil-impregnated sleeves, so that spring 113A is pivotally fixed to the swing seat 112B and the frame 10A, and the frictional force between them is reduced.

[0100] Similarly, as shown in the figure, two tensioning devices 113 can be provided, and each tensioning device 113 can be fixed to the corresponding swing seat 112B.

[0101] The linkage assembly 114 can be pivotally connected between the swing device 112 and the guide device 12 to transmit the swing movement of the swing device 112 to the guide device 12, and to cause the guide device 12 to reciprocate between a first position and a second position, and preferably to achieve linear reciprocating movement.

[0102] like Figure 1 and 2As shown, in order to achieve consistent and stable movement, a synchronizing link 115 can be provided between the swing seats 112B to connect the two swing seats 112B together. This synchronizing link 115 can be arranged coaxially with the extension shaft 113B.

[0103] Continue to refer to Figure 1 and 2 The linkage assembly may mainly include a link 114A, a cross brace 114B, and a spherical bearing 114C.

[0104] The connecting rod 114A can be pivotally connected to the cross brace 114B and the swing seat 112B via the joint bearings 114C at both ends. The joint bearings 114C can ensure that the connection can rotate to ensure the degree of freedom required for motion transmission.

[0105] As an example, the guide device 12 may mainly include a fixed seat 121, a guide shaft 122, and a sliding seat 123. The fixed seat 121 can be fixed to the frame 10A, and four such fixed seats may be provided. The guide shaft 122 may extend a predetermined distance between two fixed seats 121. The sliding seat 123 may be mounted on the guide shaft 122 via the sliding shaft 122 and may move back and forth along the axial direction of the guide shaft 122. The two ends of the cross brace 114B may be fixed to two sliding seats 123 respectively, and as described above, the connecting rod 114A may be fixed to a suitable position on the cross brace 114B via a spherical bearing 114C, for example, the middle portion fixed to the cross brace 114B is shown in the attached figure.

[0106] A mounting part 123A may be provided on the sliding base 123 for mounting or fixing the separation control device 20, and will be described in further detail below with reference to the accompanying drawings.

[0107] Figure 3 This is a schematic perspective view of the separation control device 20 of the vacuum suction cup type separation and conveying device 100 according to a non-limiting embodiment of the present utility model.

[0108] The separation control device 20 can, for example, be pivotally fixed to the guide device 12. As shown and as an example, the separation control device 20 can mainly include a first pivoting mechanism 21 and a second pivoting mechanism 22 for rotating the suction cup device 30 between different positions, respectively.

[0109] Specifically, the first pivoting mechanism 21 can be pivotally supported by the guide device 12 and allows the suction cup device 30 to change between a conveying position and a clearance position relative to the guide device 12. The second pivoting mechanism 22 is rotatably supported by the first pivoting mechanism 21, and the suction cup device 30 is fixed to the second pivoting mechanism 22, which allows the suction cup device 30 to change between a pick-up position and a conveying position relative to the guide device 12.

[0110] like Figure 3 As shown, the first pivoting mechanism 21 may mainly include a first shaft 211, a first rocker arm 212, and a first cylinder 213, etc.

[0111] The first shaft 211 may be a long shaft, and both ends of the first shaft 211 may be rotatably supported by the guide device 12. For example, both ends of the first shaft 211 may be fixed to the mounting portion 123A of the sliding seat 123 via bearings, and the first shaft 211 may be allowed to rotate freely.

[0112] The first end of the first rocker arm 212 can be fixed to the first shaft 211 and can move (e.g. rotate) together with the first shaft 211, while the second end of the first rocker arm 212 can be pivotally connected to the first cylinder 213.

[0113] The first cylinder 213 may include a first piston rod 213A and a first cylinder body 213B. The first piston rod 213A of the first cylinder 213 is pivotally connected to the second end of the first rocker arm 212, for example, via a spherical bearing. The first cylinder body 213B of the first cylinder 213 may be fixed to the guide device 12, for example, fixed to the sliding seat 123 via a first cylinder seat 214 and a first pin seat 215, and may rotate relative to the first cylinder seat 214. Preferably, a small copper sleeve may be provided at the first pin seat 215, through which the first cylinder body 213B may be pivotally mounted to the first pin seat 215 to reduce rotational friction.

[0114] In this way, the reciprocating motion of the first piston rod 213A will drive the second end of the first rocker arm 212 to reciprocate, thereby causing the first shaft 211 to rotate, for example, to rotate around the axial direction A within a predetermined angle range.

[0115] The second pivoting mechanism 22 may mainly include a second shaft 221, a second rocker arm 222, and a second cylinder 223.

[0116] The second shaft 221 can be a hollow shaft and can be sleeved on the first shaft 211. A sleeve can be provided between the second shaft 221 and the first shaft 211. For example, the sleeve can be a long copper sleeve, which is installed in the inner holes at both ends of the second shaft 221 and sleeved on the outer surface of the first shaft 211 to allow the second shaft 221 to pivot relative to the first shaft 211 and reduce friction during rotation.

[0117] The first end of the second rocker arm 222 can be fixed to the second shaft 221 and can move (e.g. rotate) together with the second shaft 221, while the second end of the second rocker arm 222 can be pivotally connected to the second cylinder 223.

[0118] The second cylinder 223 may include a second piston rod 223A and a second cylinder body 223B. The second piston rod 223A of the second cylinder 223 is pivotally connected to the second end of the second rocker arm 222, for example, via a spherical bearing. The second cylinder body 223B of the second cylinder 223 may be fixed to the first shaft 211, for example, via a second cylinder seat 224 and a second pin seat 225, and may rotate relative to the second cylinder seat 224. Preferably, a small copper sleeve may be provided at the second pin seat 225, through which the second cylinder body 223B may be pivotally mounted to the second pin seat 225 to reduce rotational friction.

[0119] In this way, the reciprocating motion of the second piston rod 223A will drive the second end of the second rocker arm 222 to reciprocate, thereby causing the second shaft 221 to rotate.

[0120] Based on the above, it can be seen that when the first shaft (long shaft) 211 of the first pivoting mechanism 21 mentioned above rotates, it can drive the second pivoting mechanism 22 to rotate together. After the first pivoting mechanism 21 rotates to its position, the second cylinder 223 in the second pivoting mechanism 22 can also operate independently to drive the second shaft 221 to rotate, thereby driving the suction cup 31 of the suction cup device 30 to rotate. In this way, the first pivoting mechanism 21 can enable the suction cup device 30 to switch between the conveying position and the avoidance position, while the second pivoting mechanism 22 can enable the suction cup device 30 to switch between the picking position and the conveying position.

[0121] Continue to refer to Figure 3 A key 221A extending along the axial direction A may be provided on the outer surface of the second shaft 221. The suction cup device 30 may be arranged on the second shaft 221 along the axial direction A, such as... Figure 1 As shown.

[0122] Figure 4 This is a schematic perspective view of the suction cup device 30 of the vacuum suction cup type separation and conveying device 100 according to a non-limiting embodiment of the present utility model.

[0123] As shown in the figure, the suction cup device 30 can be carried by the separation control device 20 and can mainly include a suction cup 31, a mounting base 32, and a suction base 33, etc.

[0124] The suction cup 31 can be any type of suction cup known in the art, used to generate a suction force by means of a vacuum to pick up or release the sheet 200 as needed.

[0125] Mounting base 32 may include a fixed upper base 32A, a fixed lower base 32B, and a fastening device. The fixed upper base 32A and fixed lower base 32B may be hinged together via a pin 32C, and a mounting groove 30A is provided on the fixed upper base 32A. The mounting groove 30A may mate with a key 221A to allow the suction cup device 30 to be positioned at different locations along the axial direction A. After the suction cup device 30 is positioned along the axial direction A, it can be securely fixed to the second shaft 221 by the fastening device.

[0126] The suction base 33 can be fixed to the fixed upper base 32A and connected to the feed line. In this way, the suction cup 31 is connected to the suction base 33 to create a vacuum in the suction cup 31 for sucking up or releasing the sheet 200.

[0127] In this way, the separation control device 20 causes the suction cup device 30 to pivot relative to the guide device 12, and the suction cup 31 selectively picks up or releases the sheet 200 to achieve the conveying of the sheet 200.

[0128] Figure 5 The schematic working principle of the suction cup device 30 according to a non-limiting embodiment of the present invention is shown; while Figures 6A to 6C A schematic diagram of the suction cup device 30 in different positions is shown.

[0129] As an example, the conveying position of the suction cup device 30 can be a position where the upper surface of the suction cup 31 is approximately horizontal, while the avoidance position of the suction cup device 30 can be a position where the suction cup 31 is deflected downwards to be as far apart as possible from the sheet 200, and the pick-up position of the suction cup device 30 can be a position where the suction cup 31 is deflected upwards to pick up the sheet 200 at the bottom of the tilted stack of sheets.

[0130] like Figure 5 As shown, the sheet stack can be arranged at a generally inclined angle, such that its position is higher on the front side (right side in the figure) and lower on the rear side (left side in the figure) relative to the direction of movement. Therefore, when the suction cup device 30 picks up the sheet 200 in the first position, the suction cup 31 needs to be deflected upwards to contact the lower surface of the front (or right) side of the sheet 200 to pick up a single sheet, and to allow it to be spaced apart from the other sheets in the sheet stack so as to individually move the picked-up sheet 200 forward, for example, to the right in the figure.

[0131] like Figure 5 The position indicated by the dashed line represents the suction cup device 30 in the pick-up position. At this time, the suction cup 31 deflects upwards to pick up the bottommost sheet 200 of the tilted stack of sheets. (As shown...) Figure 5The position indicated by the solid line represents the position where the suction cup device 30 is in the conveying position. At this time, the suction cup 31 has picked up a single sheet 200 and pivoted downwards to a roughly horizontal position to move forward (to the right in the figure) by means of the drive of the power system 10.

[0132] Figure 6A The suction cup device 30 is schematically shown in the pickup position. Figure 6B The suction cup device 30 is schematically shown in the conveying position, while Figure 6C The suction cup device 30 is schematically shown in the avoidance position. It can be seen that the suction cup device 30 deflects upward in the pick-up position and downward in the avoidance position to achieve the desired operation.

[0133] Return to reference Figure 1 The control device 40 can be connected to the power system 10, the separation control device 20 and the suction cup device 30, such that as the guide device 12 is driven to move between a first position and a second position, the suction cup 31 picks up the sheet 200 in the first position and releases the sheet 200 in the second position.

[0134] As an example, the control device 40 may mainly include a controller, program code pre-programmed into the controller, a pneumatic circuit, and multiple solenoid valves, etc.

[0135] The pneumatic circuit may include a vacuum section and a compressed air section. As an example, the vacuum section may be connected to the suction cup device 30 to control the suction or release of the sheet 200. The compressed air section may control the action of the actuators, such as controlling the action of the first cylinder 213 and the second cylinder 223, to control the rotation angle of the suction cup device 30.

[0136] An exemplary operation process can be as follows: The power system 10 can drive the separation control device 20 to move backward. When it moves to the first position (or initial position or separation station), the control device 40 can control the first solenoid valve to operate, and use compressed air to activate the first cylinder 213 of the first pivoting mechanism 21, which in turn drives the suction cup device 30 to rotate, rotating it to a position that facilitates the forward transport of the sheet 200, for example, a position where the upper surface of the suction cup 31 is approximately horizontal.

[0137] Next, the control device 40 can control the second solenoid valve to operate, and use compressed air to actuate the second cylinder 223 of the second pivot mechanism 22, causing the second shaft 221 to swing upward, so that the suction cup 31 contacts the sheet 200, such as cardboard (e.g. Figure 6A (The position shown). Before the suction cup 31 contacts the sheet 200, the third solenoid valve can be activated to introduce a vacuum into the suction cup 31 to achieve a vacuum suction operation.

[0138] After the suction cup 31 makes full contact with and holds the sheet 200, the control device 40 can control the second solenoid valve to operate, and use compressed air to actuate the second cylinder 223 of the second pivoting mechanism 22, causing the second shaft 221 therein to swing downward. At this time, the suction cup 31 will hold the bottom sheet 200 of the sheet stack (e.g., a cardboard stack), separating it from the sheet stack, and continue to rotate to a position where the sheet 200 is conveyed forward, for example, when the upper surface of the suction cup 31 is approximately horizontal (e.g., ...). Figure 6B (The location shown).

[0139] At this time, the power system 10 can drive the separation control device 20 to move forward. When the suction cup device 30 moves to the second position (i.e., the next work station), the control device 40 can control the third solenoid valve to activate, causing the vacuum in the suction cup 31 to be disconnected. At the same time, the control device 40 can control the first solenoid valve to activate, causing the first cylinder 213 of the first pivoting mechanism 21 to activate, and driving the separation control device 20 to rotate downward together, rotating to a position that can avoid the sheet 200 (e.g., Figure 6C (The location shown).

[0140] Then, the power system 10 drives the separation control device 20 to move backward to enter the next conveying cycle.

[0141] By repeating this operation, continuous feeding of sheet 200 can be achieved, thereby greatly improving the efficiency of line production.
