[0039] In an embodiment of the present invention, a spacer conveyor is provided. Refer to Figure 1 and Figure 19 As shown, the spacer conveyor includes: a spacer storage mechanism, a spacer width adjustment mechanism, and a spacer conveying mechanism; the spacer storage mechanism is a bottom stable support structure with a fixed support in the middle and movable supports on both sides, and is used to store spacers 103 and adjust the storage space according to the size of the spacers 103, wherein the spacer storage mechanism includes an installation space; the spacer width adjustment mechanism is arranged in the installation space and is used to adjust the storage space of the spacer storage mechanism according to the size of the spacers 103; the spacer conveying mechanism is arranged at the bottom of the spacer storage mechanism and is used to push the spacers 103 out of the spacer storage mechanism and convey them to the bottom of the goods 104. The conveying path of the spacers is as Figure 17 shown.

[0040] Optionally, the frame of the spacer storage mechanism is composed of aluminum profiles. The spacers 103 are polystyrene foam (EPS) spacers.

[0041] In this embodiment, refer to Figure 19As shown, the spacer conveyor can adjust the storage space of the spacer storage mechanism through the spacer width adjustment mechanism to adapt to spacers 103 of different sizes, and then convey the spacers 103 to the bottom of the goods 104 through the spacer conveying mechanism, so as to realize the flexible adjustment of the conveying width to meet the requirements of the goods 104 of different sizes for the spacers 103, thus solving the problems of poor adaptability, low adjustment efficiency and high maintenance cost of the spacer conveyor in the prior art.

[0042] In an embodiment of the present invention, referring to Figure 2 and Figure 3 as shown, the spacer storage mechanism includes a support frame 301, an intermediate support part 302 and side supports 202; the support frame 301 is a rectangular structure (such as Figure 4 as shown); the intermediate support part 302 is a strip structure, and the intermediate support part 302 is fixed in the middle of two opposite sides of the support frame 301 through vertical supports 303a; the side supports are slidably connected to the support frame 301, the side supports include a first part and a second part, and the first part and the second part are respectively arranged on two opposite sides of the support frame 301; the first part and the second part slide along a direction perpendicular to the extension direction of the intermediate support part 302; wherein, the first part and the second part are used for storing spacers 103.

[0043] In an embodiment of the present invention, the first part includes a first vertical column, a second vertical column, a first bottom beam and a first cross beam; the second part includes a third vertical column, a fourth vertical column, a second bottom beam and a second cross beam; wherein, the first vertical column and the second vertical column are arranged in parallel at intervals, and the third vertical column and the fourth vertical column are arranged in parallel at intervals; the bottoms of the first vertical column and the second vertical column are connected by the first bottom beam; the tops of the first vertical column and the second vertical column are connected by the first cross beam; the bottoms of the third vertical column and the fourth vertical column are connected by the second bottom beam; the tops of the third vertical column and the fourth vertical column are connected by the second cross beam.

[0044] In an embodiment of the present invention, the spacer storage mechanism further includes: a first spacer support portion, a second spacer support portion, a first spacer top limiting portion, a second spacer top limiting portion, a first spacer side limiting portion, and a second spacer side limiting portion; the first spacer support portion is fixed to one side of the first column and the second column close to the bottom beam and is parallel to the first bottom beam; the first spacer top limiting portion is fixed to one side of the first column and the second column close to the cross beam and is parallel to the first cross beam; one end of the first spacer side limiting portion is fixed to the first spacer top limiting portion, and the other end is fixed to the second column; the second spacer support portion is fixed to one side of the third column and the fourth column close to the bottom beam and is parallel to the second bottom beam; the second spacer top limiting portion is fixed to one side of the third column and the fourth column close to the cross beam and is parallel to the second cross beam; one end of the second spacer side limiting portion is fixed to the second spacer top limiting portion, and the other end is fixed to the third column; a first door is provided on the first column, and a second door is provided on the fourth column; wherein, the side drag, the first spacer support portion, the second spacer support portion, the first spacer top limiting portion, the second spacer top limiting portion, the first spacer side limiting portion, the second spacer side limiting portion, the first door, and the second door form a spacer storage bin.

[0045] Specifically, referring to Figure 8 As shown, the side of the door frame 204 is fixed to the side support 202 through a hinge 141, and a door is installed inside the door frame 204, so that the door frame 204 and the door move together with the side drag. A handle 501 is installed on the door to facilitate the operator to close it.

[0046] Understandably, referring to Figure 5 As shown, since the width of the spacer 103 is variable, the spacer storage mechanism is composed of a spacer middle support portion 302 fixed in the middle on the support frame 301 and movable side supports 202 on both sides, forming a bottom stable support structure with a fixed middle support and movable end supports. The side support 202, the spacer end support 401, the spacer top limit 402, and the spacer side limit 403 form a five-sided limit for the stacked spacers, and then the door frame 204 forms the last-sided limit for the stacked spacers 103 to ensure the neat stacking of the spacers 103 in the bin.

[0047] In an embodiment of the present invention, the spacer storage mechanism includes a plurality of the spacer storage bins. For example, as Figure 19 shown, there are a first spacer storage bin 105 and a second spacer storage bin 106 in the spacer conveyor, which can store two stacks of spacers.

[0048] In an embodiment of the present invention, referring to Figure 15As shown, multiple light control seats 132 are installed on the side support 202, and the photoelectric switch 135 is on the light control seat 132 to monitor the quantity of the cushion blocks 103 in the silo. When the cushion blocks 103 in the first cushion block storage bin 105 or the second cushion block storage bin 106 are used up, the control system will switch to use the silo on the other side and issue a warning at the same time, and the worker will replenish the cushion blocks 103. The two silos are used alternately to avoid production interruption caused by insufficient quantity of the cushion blocks 103 during packaging.

[0049] In an embodiment of the present invention, referring to Figure 9 and Figure 10 As shown, the cushion block conveying mechanism includes: a cylinder 609, a cylinder push plate 610, a side pushing structure 203 (referring to Figure 6 and Figure 7 as shown), a first guide rail 304, a slider and an angle seat 619; wherein, the cylinder 609 is fixed to the bottom surface of the intermediate support portion 302 through a bracket; the side pushing structure 203 is arranged at one end of the intermediate support portion 302, and the cylinder push plate 610 is fixed to the end of the side pushing structure 203; the head of the cylinder rod is connected to the cylinder push plate 610; the fourth guide rail 611 is fixed to the side pushing structure 203; the slider is connected to the angle seat 619 fixed to the intermediate support portion 302; when the cylinder 609 acts, it drives the side pushing structure 203 to move towards the middle, and pushes the cushion block 103 at the bottom of the storage bin into the first guide rail 304.

[0050] Optionally, the length L of the side push is greater than the width of the cushion block 103. Since the length L of the side push is greater than the width of the cushion block 103, the upper cushion blocks 103 are prevented from continuing to fall. When the cylinder 609 resets and drives the side push to extend outwards, space is vacated for the upper cushion blocks 103 to fall, preparing for the next push plate.

[0051] In an embodiment of the present invention, the intermediate support portion 302 is fixed to the support frame 301 through a vertical support 303a to form a storage space; wherein the cushion block width adjusting mechanism and the cushion block pushing mechanism are arranged in the storage space, and optionally, the cylinder 609 is stored in the storage space; the guide rail is fixed to the support frame 301 through a vertical support 303b, and a moving space for the side support 202 and an installation space for the cushion block width adjusting mechanism and the cushion block pushing mechanism are formed at the bottom.

[0052] In an embodiment of the present invention, the cushion block conveyor further includes a chassis 201, which is arranged at the bottom of the support frame 301, and the chassis 201 includes feet 608. Optionally, the chassis 201 is built by aluminum profiles; the support frame 301 is a solid frame composed of aluminum profiles to support the whole equipment; 4 feet 608 are installed at the bottom of the chassis 201 to facilitate the adjustment of the height and level of the whole equipment.

[0053] In an embodiment of the present invention, referring to Figure 9 as shown, the spacer conveyor further includes: a reduction motor 601, a double-row sprocket 604, a passive sprocket 605, a sprocket seat 603, a short chain 606, and a long chain 607. Among them, the double-row sprocket 604 and the passive sprocket 605 are fixed to both ends of the bottom surface of the first guide rail 304 through the sprocket seat 603. The long chain 607 is installed on the passive sprocket 605. The long chain 607 is in a central position to avoid deflection force when pushing the plate. The reduction motor 601 is offset and installed at one end of the first guide rail 304, and the drive sprocket 602 thereon transfers power to the double-row sprocket 604 through the short chain 606.

[0054] In an embodiment of the present invention, referring to Figure 11 、 Figure 15 and Figure 16 as shown, the spacer conveying mechanism further includes: a slide plate 802, a chain, a chain connection seat 801, a push rod 803, and a push plate 804; the chain connection seat 801 is installed on the bottom surface of the slide plate 802, and the push rod 803 is installed on the upper surface of the slide plate 802; the slide plate 802, the chain connection seat 801, and the push rod 803 are fixed by fasteners; the chain is arranged on the chain connection seat 801; the push plate 804 is fixed to the head of the push rod 803; after the chain runs, it drives the slide plate 802 and the push rod 803 to perform linear motion, and the push plate 804 at the head of the push rod 803 pushes the spacer 103 on the first guide rail under the goods 104.

[0055] Optionally, the slide plate 802 is made of wear-resistant nylon material; there are raised steps at both ends of the slide plate 802, and the steps are embedded in the aluminum profile installation groove of the first guide rail 304, which can be used as a simple linear motion guide rail.

[0056] Optionally, there are small round holes at both ends of the chain connection seat 801, and the pin shaft 121 for installing the long chain 607 can be inserted. Through the aluminum profile installation groove of the first guide rail 304, the tension of the chain can be conveniently adjusted.

[0057] In an embodiment of the present invention, in order to prevent the slide plate 802 from working beyond the range, swing switches 614 and proximity switches 615 are installed at both ends of the first guide rail 304. The swing switch 614 is used to control the stroke limit, and the proximity switch 615 is used for near and far point positioning. The swing switch 614 and the proximity switch 615 are respectively fixed to the first guide rail 304 through a swing switch angle seat 612 and a proximity switch angle seat 613.

[0058] In an embodiment of the present invention, the spacer conveyor further includes a linkage mechanism; the linkage mechanism includes a connecting rod 808 and a connecting rod seat 807; the side drag includes a second guide rail 809; one end of the connecting rod 808 is fixed to the upper edge of the side support 202 through the connecting rod seat 807, and the other end is fixed to the slider of the second guide rail 809 through the connecting rod seat 807.

[0059] Specifically, the third guide rail 701 is fixed on both sides of the support frame 301, and the left and right side supports 202 are fixed to the sliders of the third guide rail 701 through angle seats 805. Since the stacking height of the spacers 103 is relatively high, it is not firm enough to fix the side support 202 only by the angle seat 805. Therefore, a set of linkage mechanism can be added between the left and right side supports 202 to enhance the rigidity of the whole device. One end of the connecting rod 808 is fixed to the upper edge of the side support 202 through the connecting rod seat 807, and the other end is fixed to the slider of the second guide rail 809 through the connecting rod seat 810. The second guide rail 809 is fixed to the aluminum profile column of the side support 202. The middle parts of the four connecting rods 808 are connected by a pin shaft 133 and separated from each other by a spacer sleeve 134.

[0060] This linkage mechanism ensures the parallelism of the left and right side supports 202, and even after stacking a large number of spacers 103, it will not cause the inclination of the side supports 202.

[0061] In an embodiment of the present invention, referring to Figure 12 and Figure 13 as shown, the spacer conveyor further includes a centering lead screw 806; positive nuts 902 and reverse nuts 111 are respectively installed at the positive and reverse threaded parts on both sides of the centering lead screw 806, and are fixed to the side support 202 by a lead screw nut seat 901. Both ends of the centering lead screw 806 are fixed in a bearing seat 903 through flanged oil-free bearings 904. An oil injection nozzle 905 is installed on the bearing seat 903, and the bearings inside can be lubricated regularly. Two locking nuts 906 are installed at the end of the centering lead screw 806, which can adjust the bearing clearance to avoid jamming when the lead screw rotates.

[0062] In an embodiment of the present invention, referring to Figure 14 as shown, since the centering lead screw 806 is located below the first guide rail 304, it is inconvenient to adjust when the adjusting handwheel 617 is directly installed on the lead screw. A bearing seat 903 is added on the side as a transition, and a pair of sprockets 618 are added on the pin shaft 121 and the centering lead screw 806 as a rotational transition.

[0063] In an embodiment of the present invention, a spacer packing system is provided, as Figure 18 、 Figure 19 and Figure 20As shown in the figure. The spacer packing system includes: a spacer conveyor 100, a chain conveyor 101, and a horizontal winding machine 102. Among them, one side of the chain conveyor 101 is connected to the spacer conveyor 100, and the other side is connected to the horizontal winding machine 102. The spacers 103 are stored in the spacer conveyor 100. When the goods 104 pass by, they are conveyed onto the chain conveyor 101, and the spacers 103 are placed under the goods 104. According to the length of the goods 104, the control system automatically pads multiple spacers 103. After the goods 104 are film-wound by the horizontal winding machine 102, they are finally taken out by a forklift.

[0064] In an embodiment of the present invention, spacers 103 of different widths are pushed onto the chain conveyor 101 by the spacer conveyor 100, and they always remain consistent with the center of the goods 104 on the roller path. Therefore, when using spacers 103 of different widths, the relative positions of the slide plate 802 and the push rod 803 are adjusted. In this way, when the stroke range of the slide plate 802 remains unchanged, the centers of the spacers 103 of different widths can always remain unchanged after being pushed out.
