[0036] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0037] An embodiment of the present application provides a distance adjusting system, as shown in the accompanying drawings, comprising a separating device 100, a cutting device 200 and a distance adjusting device 300. Figure 1

[0038] The cutting device 200 is used to cut two groups of sheet products 400 arranged adjacently on the continuous strip product 500, and each group of sheet products 400 is composed of a plurality of sheet products 400 arranged with each other. The two groups of sheet products 400 are only the specific group number of the sheet products 400 provided in the embodiment, and are only for the convenience of description. In other embodiments, the sheet products 400 can also be cut into multiple groups of sheet products 400, such as three groups of sheet products 400, etc.

[0039] The separating device 100 is arranged at the downstream side of the cutting device 200, and the separating device 100 receives the two groups of sheet products 400 and separates them to the required distance in the width direction, that is, adjusts the distance between the two groups of sheet products 400.

[0040] The distance adjusting device 300 is arranged at the downstream side of the separating device 100, and is used to pick up the separated sheet products 400 and adjust them to the required distance in the flow direction, that is, adjust the distance between each sheet product 400 in each group of sheet products 400, which is the distance along the movement direction or flow direction of the distance adjusting device 300.

[0041] Figure 6 The application state schematic diagram of the distance adjusting system provided by the present application is shown in the accompanying drawings, Figure 6 The left side in the middle is the strip product 500, which is first formed into a plurality of sheet products 400 after being cut by the cutting device 200, and then the sheet products 400 are received by the separating device 100, which separates the sheet products 400 to the required distance. After the distance adjusting device 300 receives the sheet products 400, it adjusts the sheet products 400 to the required distance in the flow direction.

[0042] The separating device 100 comprises a first guide part 121 and two groups of picking mechanisms 110, as shown in the accompanying drawings, Figure 2 、 Figure 3 and Figure 4 ​As shown, the two groups of pickup mechanisms 110 are rotatably arranged opposite to the first guide part 121, and when the two groups of pickup mechanisms 110 contact and rotate opposite to the first guide part 121, the first guide part 121 drives the two groups of pickup mechanisms 110 to relatively move along the axis of the rotation axis. The rotation axis here refers to a virtual rotation axis of the pickup mechanism 110 and the first guide part 121, and the purpose is to describe the relative position and movement relationship of the pickup mechanism 110 and the first guide part 121, rather than specifically indicating that there is a physical rotation axis.

[0043] The separation device 100 provided by the utility model is used for picking up the sheet products 400 after the continuous strip is cut to form two groups of sheet products 400 arranged adjacently, and when the first guide part 121 rotates opposite to the two groups of pickup mechanisms 110, the two groups of pickup mechanisms 110 relatively move along the axis of the rotation axis, so that the distance between the two groups of pickup mechanisms 110 is changed, the spacing between the two groups of sheet products 400 is adjusted, and the separation device 100 is suitable for subsequent production equipment or process.

[0044] The separation device 100 provided by the utility model adjusts the spacing of the two groups of pickup mechanisms 110 by rotating the first guide part 121 opposite to the two groups of pickup mechanisms 110, and does not need to introduce an additional adjusting mechanism, so that the overall structure is simple. Especially in the production equipment of the continuous strip or the sheet product 400, rotary driving is a common driving form, and the pickup mechanism 110 often has a relative rotation movement relationship with the upstream equipment and the downstream equipment, and the spacing of the two groups of pickup mechanisms 110 is adjusted by rotating the first guide part 121 opposite to the two groups of pickup mechanisms 110, so that the spacing adjustment of the pickup mechanism 110 is realized on the basis of the existing movement form of the pickup mechanism 110, the pickup mechanism 110 is applied to the existing production equipment, and the applicability is wide.

[0045] After the first guide part 121 realizes the spacing adjustment effect between the two groups of pickup mechanisms 110, the separation device 100 can move the sheet product 400 to the spacing adjusting device 300 during the process that the pickup mechanism 110 contacts the first guide part 121, and the spacing adjustment between the two groups of sheet products 400 is completed.

[0046] In some embodiments, the separation device 100 comprises at least one second guide part 122, and at least two groups of pickup mechanisms 110 are rotatably arranged opposite to the second guide part 122, and when the at least two groups of pickup mechanisms 110 contact and rotate opposite to the second guide part 122, the at least two groups of pickup mechanisms 110 are relatively fixed.

[0047] In the process that the picking mechanism 110 contacts with the first guide part 121, the interval between the picking mechanisms 110 is always in a changing state. After the second guide part 122 is arranged, the picking mechanism 110 can pick the sheet product 400 from the cutting device 200 or move the sheet product 400 to the distance adjusting device 300 in the process that the second guide part 122 contacts with the picking mechanism 110. At this time, the interval between the two groups of picking mechanisms 110 remains unchanged when the picking mechanism 110 picks or moves the sheet product 400. The picking mechanism 110 can keep a longer stable contact or exchange state with the cutting device 200 or the separating device 100, and can more smoothly pick or move the sheet product 400.

[0048] In some embodiments, as shown in Figure 4 the first guide part 121 and the second guide part 122 are arranged continuously. In this way, the picking mechanism 110 is more stable in the process that the picking mechanism 110 changes from contacting with the first guide part 121 to contacting with the second guide part 122. The picking device is avoided from vibrating in this process, and the sheet product 400 is avoided from falling off or moving on the picking device in this process. The picking mechanism 110 is more likely to keep the holding effect on the sheet product 400.

[0049] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 5 the first guide part 121 and the second guide part 122 are arranged on the cam 120, and the cam 120 is rotatably arranged relative to the picking mechanism 110. The first guide part 121 and the second guide part 122 are grooves under the surface of the cam 120. Figure 3 is a structural schematic view of the cam 120, Figure 4 is a structural schematic view of the surface of the cam 120, Figure 5 is a partial structural schematic view of the separating device 100.

[0050] Arranging the first guide part 121 and the second guide part 122 on the cam 120 and rotatably arranging the cam 120 relative to the picking mechanism 110 can simply realize the rotatable arrangement between the first guide part 121 and the second guide part 122 and the picking mechanism 110. The cam 120 can be driven to rotate alone, the picking mechanism 110 can be driven to rotate alone, or the cam 120 and the picking mechanism 110 can be driven to rotate simultaneously, and relative rotation is generated between the two.

[0051] In other embodiments, the first guide part 121 and the second guide part 122 are arranged on the cam 120, and the first guide part 121 and the second guide part 122 are convex tracks on the surface of the cam 120.

[0052] In some embodiments, as shown in Figure 4 The third guide portion 123 is provided opposite to the at least two groups of picking mechanisms 110, and the at least two groups of picking mechanisms 110 are fixed relative to each other when the at least two groups of picking mechanisms 110 contact and rotate relative to the third guide portion 123. The distance between the at least two groups of picking mechanisms 110 when the at least two groups of picking mechanisms 110 rotate relative to the third guide portion 123 is different from the distance between the at least two groups of picking mechanisms 110 when the at least two groups of picking mechanisms 110 rotate relative to the second guide portion 122.

[0053] The distance between the two groups of picking mechanisms 110 has changed after the picking mechanisms 110 pass through the first guide portion 121. Therefore, the second guide portion 122 cannot be simultaneously arranged at a position that contacts the picking mechanisms 110 when the picking mechanisms 110 pick up and release the sheet product 400. Therefore, the third guide portion 123 is arranged, and the second guide portion 122 is arranged to maintain contact with the picking mechanisms 110 during the picking mechanisms 110 picking up the sheet product 400. The third guide portion 123 is arranged to maintain contact with the picking mechanisms 110 during the picking mechanisms 110 releasing the sheet product 400. Thus, the picking mechanisms 110 can maintain smooth contact with the cutting device 200 and the distance adjusting device 300 during the picking mechanisms 110 picking up and releasing the sheet product 400, and the picking mechanisms 110 can pick up and release the sheet product 400 more smoothly.

[0054] Specifically, as shown in Figure 3 and Figure 4 The second guide portion 122 and the third guide portion 123 can be arranged to extend along the circumference of the cam 120 and remain unchanged in the axial direction of the rotation axis. The first guide portion 121 can be arranged to extend along the circumference of the cam 120 and continuously change position in the axial direction of the rotation axis. When the surface of the cam 120 is unfolded, as shown in Figure 4 The second guide portion 122 and the third guide portion 123 extend only in the horizontal direction, and the first guide portion 121 extends in both the horizontal direction and the vertical direction.

[0055] Whether the first guide portion 121 and the second guide portion 122 are arranged as convex tracks or as grooves, the picking mechanisms 110 can be driven to move relative to each other or maintain a constant distance in the axial direction of the rotation axis.

[0056] In some embodiments, the number of the first guide portion 121 and the second guide portion 122 is the same as the number of the picking mechanisms 110, and each group of picking mechanisms 110 corresponds to one first guide portion 121 and one second guide portion 122, as shown in Figure 2 , Figure 3 , Figure 4and Figure 5 At this time, each group of pickup mechanisms 110 changes the position along the axial direction of the rotation axis by the first guide part 121 or the second guide part 122 during rotation, thereby changing or maintaining the distance between the pickup mechanisms 110.

[0057] Further, the pickup mechanisms 110, the first guide part 121 and the second guide part 122 can also be arranged symmetrically left and right, with the symmetric center axis perpendicular to the axial direction of the rotation axis.

[0058] In some embodiments, as shown in Figure 3 and Figure 4 The number of the first guide part 121, the second guide part 122 and the third guide part 123 is set to two, and the number of the pickup mechanisms 110 is two groups correspondingly.

[0059] In other embodiments, as shown in Figure 9 and Figure 10 The number of the first guide part 121, the second guide part 122 and the third guide part 123 is set to four, and they are arranged symmetrically left and right. The two first guide parts 121 on the same side have different position change rates along the axial direction of the rotation axis, so that the four groups of pickup mechanisms 110 can all change the distance between each other, as shown in Figure 10

[0060] In other embodiments, the position of at least one group of pickup mechanisms 110 remains unchanged. When two groups of pickup mechanisms 110 are arranged, only the position of one group of pickup mechanisms 110 changes along the axial direction of the rotation axis under the action of the first guide part 121, so that the two groups of pickup mechanisms 110 move relatively along the axial direction of the rotation axis, thereby changing the distance between the two groups of pickup mechanisms 110 and achieving the effect of the separation device 100. When more than two groups of pickup mechanisms 110 are arranged, the position of one group of pickup mechanisms 110 can still remain unchanged, and the positions of the other pickup mechanisms 110 change, so that all the pickup mechanisms 110 move relatively along the axial direction of the rotation axis, as shown in Figure 7 and Figure 8 The number of the first guide part 121, the second guide part 122 and the third guide part 123 is set to two, and the two groups of pickup mechanisms 110 on the outside correspond to the two groups of first guide parts 121, second guide parts 122 and third guide parts 123, and the middle group of pickup mechanisms 110 does not change the position, so that the three groups of pickup mechanisms 110 can all change the distance between each other, as shown in Figure 8

[0061] In optional embodiments, as shown in Figure 2 and​​Figure 5 As shown in the figure, each group of pickup mechanism 110 includes at least two pickup pads 111 arranged circumferentially along the rotation direction, and the first guide part 121 drives the pickup pads 111 to move along the axial direction of the rotation axis. The plurality of pickup pads 111 are arranged to pick up the sheet product 400, and the position of each pickup pad 111 can be adjusted independently. For example, when one pickup pad 111 is driven by the first guide part 121 to move along the axial direction of the rotation, the position of the pickup pad 111 will not affect the position of the pickup pad 111 that is kept unchanged by the second guide part 122 or the third guide part 123.

[0062] In an optional embodiment, as shown in the figure, the pickup pad 111 is also connected with an air suction unit, which includes an air suction pipe 112 and an air path system. Figure 2

[0063] The air path system further includes a main air pipe 114 and a gas distribution disc 113. The main air pipe 114 is used to be connected with an air source, and the plurality of gas distribution discs 113 are respectively used to be connected with the air suction pipes 112 on the different pickup pads 111, and the air suction pipes 112 are communicated with the pickup pads 111. The air path system generates a negative pressure, and the negative pressure passes through the main air pipe 114, the gas distribution disc 113 and the air suction pipe 112, and then generates a negative pressure on the surface of the pickup pad 111, so as to suck the sheet product 400.

[0064] The negative pressure generated by the air suction unit is used to suck the sheet product 400, which is convenient for sucking and releasing the sheet product 400, and is also convenient for keeping the posture of the sheet product 400 on the pickup pad 111.

[0065] In an optional embodiment, as shown in the figures, Figure 2 and Figure 5 As shown in the figure, the driving shaft 131 is used to drive the pickup mechanism 110 to rotate, and the pickup mechanism 110 includes the pickup pad 111. Each pickup pad 111 is fixedly connected with the receiving part 115 and the sliding block 134. The sliding block 134 is slidably installed on the sliding block support plate 133, and the sliding block support plate 133 is installed on the connecting frame 132. The two ends of the connecting frame 132 are respectively installed on the driving shaft 131. The driving shaft 131 rotates to drive the pickup pad 111 to rotate through the connecting frame 132, the sliding block support plate 133 and the sliding block 134.

[0066] ​The cam 120 and the driving shaft 131 are relatively independent in movement, for example, the cam 120 can be mounted on the driving shaft 131 through a coupling, so that the rotation of the driving shaft 131 does not affect the cam 120, the cam 120 always remains unchanged, so that the driving shaft 131 can drive the pickup pad 111 to rotate relative to the cam 120. The first guide part 121, the second guide part 122 and the third guide part 123 are all set as grooves on the surface of the cam 120, and the first guide part 121, the second guide part 122 and the third guide part 123 are sequentially and continuously arranged between each other, as shown in Figure 3 and Figure 4 The follower 115 is arranged in the grooves of the first guide part 121, the second guide part 122 and the third guide part 123, and the follower 115 can specifically adopt a roller.

[0067] When the driving shaft 131 rotates, it drives the pickup pad 111 to rotate, and in turn drives the follower 115 to rotate in the groove on the surface of the cam 120. When the follower 115 contacts the second guide part 122 and the third guide part 123, the relative position between the two pickup pads 111 can be fixed due to the fact that the second guide part 122 and the third guide part 123 do not change in the axial direction of the rotation shaft. When the follower 115 contacts the first guide part 121, the follower 115 moves in the axial direction of the rotation shaft due to the fact that the first guide part 121 continuously changes in the axial direction of the rotation shaft, so that the pickup pad 111 moves in the axial direction of the rotation shaft when the follower 115 rotates in the groove on the surface of the cam 120, and in turn the relative position between the two pickup pads 111 changes.

[0068] The slidable direction of the slider 134 on the slider support plate 133 is the axial direction of the driving shaft 131, so when the follower 115 moves in the axial direction of the rotation shaft, the slider 134 slides on the slider support plate 133, and in turn drives the pickup pad 111 to move in the axial direction of the rotation shaft. The slider 134 and the slider support plate 133 form a sliding guide mechanism, which can make the pickup pad 111 more stable when moving in the axial direction of the rotation shaft.

[0069] The sheet product 400 mentioned in the above embodiments can specifically refer to any one of a hygiene product, a medical product and an absorbent product.

[0070] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
