Description

Scroll conveying system

Technical Field

The invention relates to a reel conveying system.

Background

In the technology of automatic continuous roll forming of coiled materials, the storage and conveying technology of reel shafts (winding cores) is involved, and the overall design requirements are as follows: several reels are stored for automatic access to a single reel, and when the reel is needed, the spindle is transported to a specific position for winding up the web.

Chinese patent: 201710065725.2 discloses an automatic winder for small winding cores, which extracts the storage technical principle about the winding shaft (winding core) as follows: the method comprises the following steps of arranging a core feeding and winding mechanism, wherein the core feeding and winding mechanism is used for placing a winding core and feeding the winding core into a roll changing station. The core feeding mechanism 4 comprises a shell 41 fixed on the frame 1, a baffle 42 hinged at the winding outlet of the shell 41, a push plate 43 arranged in the shell 41 and opposite to the baffle 42, and a third air cylinder 44 fixed on the shell 41 for pushing and pulling the push plate 43. The shell 41 is large in top and small in bottom, the upper portion of the shell can accommodate multiple rows of winding cores, the lower portion of the shell can accommodate only one winding core, and the push plate 43 is inverted Z-shaped and comprises a horizontal supporting plate, a vertical plate connected with the horizontal supporting plate and a horizontal baffle connected with the upper end of the vertical plate. Fig. 3 shows the original state of the reel changing mechanism, when feeding is needed, the third air cylinder 44 pushes the pushing plate 43 forward, and the winding core is fixed on the horizontal supporting plate under the action of the gravity of the baffle plate 42. When the clamping position is reached, the air cylinder 44 is retracted after the mandrel 232 clamps the workpiece, and the next feeding is waited. If the weight of the shutter is small due to the thin material of the shutter, a torsion spring may be provided between the shutter 42 and the housing 41 to increase the resistance of the shutter 42 pushing outward. "

A problem exists in the above-mentioned storage technology for winding shafts (cores), as shown in fig. 1-1, the winding shaft (core) accommodated in the casing 41 will fall down into the channel rd with a smaller cross section singly under the action of its own weight, however, at the intersection of the casing 41 accommodating the winding shaft and the channel rd with a smaller cross section, there may be two adjacent winding shafts m1 and m2 pressed against each other at the entrance of the channel rd, so as to form a "bridge" to hold the winding shafts above the winding shaft m1 and the winding shaft m2, so that the winding shafts in the casing 41 cannot fall into the channel rd, and thus the winding shafts cannot be taken out.

referring to fig. 1, 2, 3, 4, 5 and 6, the reel 11 is provided with a first through groove 104, the first through groove 104 penetrates through the outer contour of the reel 11, and one end opening T2 of the first through groove 104 is located in the card slot 40; the clamp plate 201 and the latch 204 connected to the clamp plate 201 are further included, the clamp block 208 is fixed on the back of the clamp plate 201 and is opposite to the second side wall S2 in the slot 40 (when the coil start end E is located between the clamp block 208 and the second side wall S2, the clamp plate 201 can press the coil start end E against the second side wall S2); the pin 204 slides in the first through slot 104 to drive the clamping plate 201 to enter or leave the clamping slot 40, so as to drive the clamping block 208 to abut against or separate from the second side wall S2 of the clamping slot 40 (similarly, it can also be designed to abut against or separate the clamping block 208 from the first side wall S1), when specifically designed, the first side wall S1 or the second side wall S2 can be selected as a clamping surface as needed, as long as any one of the two side walls (the first side wall S1 or the second side wall S2) on the clamping slot 40 abuts against the clamping block 208, the coil starting end E can be clamped (the coil starting end E is sent between the first side wall S1 or the second side wall S2 and the clamping block 208), and of course, in order to increase the clamping force, a stripe or texture can be provided on the first side wall S1 or the second side wall S2, so as to increase the friction force.

Referring to fig. 1, the clamping block 208 and the second side wall S2 are illustrated as abutting, the clamping block 208 can be fixed to the back of the clamping plate 201 to abut against the bottom surface (i.e., the second side wall S2) of the slot 40, when the pin 204 moves in the slot 40, as indicated by the arrow SR4 in fig. 1, the clamping plate 201 drives the clamping block 208 to move toward the outside of the slot 40, and the clamping block 208 is sent out of the slot 40, as shown in fig. 6, at this time, the first clamping plate 504 and the second clamping plate 505 can send the start end E of the clamped coil into the slot 40 along the direction parallel to the second side wall S2; the latch 204 then moves in the opposite direction within the pocket 40, as indicated by the arrow SR3 in fig. 1 and 5, and the clamp plate 201 moves the clamp block 208 toward the pocket 40, and the clamp block 208 enters the pocket 40 and abuts the bottom surface (i.e., the second side wall S2) of the pocket 40 to press the web start end E into the pocket 40.

For the design of the moving manner of the clamping block 208 in the slot 40, the clamping block 208 can also be moved in the vertical direction to be attached to or detached from the second sidewall S2, as long as the clamping block 208 can be abutted against the second sidewall S2 or detached from the second sidewall S2, in this scheme, the start end E of the coil can be fed into the space between the second sidewall S2 and the clamping block 208 in the slot 40 when the clamping block 208 is lifted away from the second sidewall S2, so that the start end E of the coil can be pressed down on the second sidewall S2 by the clamping block 208.

The latch 204 slides in the first through groove 104, and the power can be pushed by the telescopic rod of the cylinder, specifically, referring to fig. 5, the system further includes a first cylinder 291 and a second cylinder 292, the telescopic rod of the first cylinder 291 faces the first through groove 104 (the first through groove 104 penetrates through the outer contour of the reel, and the opening T2 at one end of the first through groove 104 is located in the clamping groove 40, then the opening T1 at the other end of the first through groove 104 is located on the outer contour of the reel, only the telescopic rod of the first cylinder 291 needs to face the opening located on the outer contour of the reel 11, which may be referred to as a second opening T1, as shown in fig. 4), the reels 11 located in the left sliding support frame 3-1 and the right sliding support frame 3-2 can be adjusted by rotation, so that the second opening T1 faces the telescopic rod of the first cylinder 291, and at this time, the telescopic rod of the second cylinder 292 faces the clamping plate 201.

The telescopic rod of the first cylinder 291 is extended to push the end of the pin 204 in the first through slot 104, so that the pin 204 slides in the first through slot 104, and the clamping plate 201 is pushed out of the slot 40, so that the clamping block 208 is separated from the first side wall S1 or the second side wall S2 of the slot 40, so that the first clamping plate 504 and the second clamping plate 505 feed the start end E of the clamped coil into the slot 40, and then the telescopic rod of the second cylinder 292 pushes the clamping plate 201 to move the clamping plate 201 in the opposite direction into the slot 40, so that the clamping plate 201 is brought into the slot 40 to press the start end E of the coil in the slot 40.

In the above, the first cylinder 291 and the second cylinder 292 may be configured to be movable, and as the coiled material is coiled, the diameter of the coiled material increases, the first cylinder 291 and the second cylinder 292 may move to avoid touching the coiled material, or the first cylinder 291 and the second cylinder 292 may also be configured to be stationary, at this time, the telescopic rods of the cylinders should meet the requirement that when the telescopic rods are in a retraction state, and the coiled material is at the maximum diameter, the telescopic rods do not touch the coiled material; the first cylinder 291 may also be provided on the lift mounts 1-3 (see description below for details). The above power arrangement may facilitate the switching of the reel 11, especially in automated operations, which is aligned so as to clamp the coil start end E, with the first cylinder 291 and the second cylinder 292 retracted without affecting the winding up of the coil.

The sliding of the bolt 204 in the first through slot 104 can be powered by an expansion link of the cylinder, and the specific scheme can be further designed as follows:

The end of the top post 102 may be spherical, and the latch 204 may be retracted during the pushing process of the side walls of the first recess 202 and the second recess 203, so as to have the effect of further fixing the clamping block 208, and when they reach the designed position, they may be locked to prevent them from loosening and slipping.

Further, the first side wall S1 and the second side wall S2 of the card slot 40 are relatively inclined to form an included angle t (or the first side wall S1 is horizontal and the second side wall S2 is inclined); the sliding direction of the latch 204 in the first through slot 104 is parallel to the first side wall S1 or the second side wall S2.

Referring to fig. 1, 2 and 13, the sliding direction of the pin 204 in the first through slot 104 is parallel to the first side wall S1, in this embodiment, the clamp block 208 is opposite to the second side wall S2, which can be far away from or close to the second side wall S2, so as to separate or abut against the second side wall S2 of the card slot 40, as shown in fig. 13, when the sliding direction of the pin 204 in the first through slot 104 is parallel to the first side wall S1, as shown by the arrow SR4 in fig. 13, the pin 204 pushes the clamp plate 201 out of the card slot 40, the clamp block 208 on the clamp plate 201 is also pushed out to gradually separate (far away) from the second side wall S2, as the clamp plate 201 moves in the arrow SR4 direction, the gap G3 between the clamp block 208 and the second side wall S2 is gradually increased, so that the first card 504 and the second card 505 carrying the start end E enter the card slot 40 from the gap G3, the final size of the gap G3 is determined by the design of the sliding travel of the plug 204 in the first through slot 104.

The first card 504 and the second card 505 are used with the reel 11 of the present invention, and please refer to the above for the specific principle and effect. In another embodiment, as shown in fig. 14, the first clamping plate 504 is horizontally fixed, and the end of the second clamping plate 505 can rotate downwards; the second clamping plate 505 rotates to approach or depart from the first clamping plate 504 to clamp or unclamp the web. When it is desired to grip a roll R1, the end of the second jaw 505 is rotated downwardly about the pivot 78 by the third cylinder 718 so that the first and second jaws 504, 505 are opened, the roll R1 passes through the gap G5 between the first and second jaws 504, 505 in the direction of arrow SR7, the roll entering the gap G5 is stretched downwardly and rides on the second jaw 505, which is now tilted downwardly, prevents the roll from creasing during forward advancement, after the start of the roll R1 enters the gap G5 between the first and second jaws 504, 505, the third cylinder 718 pushes the second jaw 505 upwardly, bringing the second jaw 505 closer to the back of the first jaw 504, thereby clamping the start E of the gap G5 between the first and second jaws 504, 505, after which the roll gripper assembly (including the third cylinder 718) can be pushed forwardly by the action of the third cylinder push rod 503, so that the first card 504 and the second card 505 hold the start end E of the roll R1 and push it forward into the slot 40 of the reel, in the process, the first gap d1 and the second gap d2 facing each other are opposite to the clamp block 208, when the clamp block 208 is pressed down, the clamp block 208 presses the roll at the first gap d1 and the second gap d2 facing each other without pressing the first card 504 and the second card 505, when the clamp block 208 of the slot 40 holds the start end E of the roll entering the slot 40, the third cylinder 718 is deflated or slightly loosened to loosen the holding of the start end E of the roll, the clamp push rod 503 moves in the opposite direction, the first card 504 and the second card 505 are withdrawn from the slot 40, at this time, the start end E of the roll is left in the slot 40 of the reel and is clamped by the clamp block 208, and the first card 504 and the second card 505 withdrawn from the slot 40 in the opposite direction can serve the purpose of guiding the roll R1, that is, when the spool rotates to wind the coil, the coil is wound up after passing through the gap G5 between the first catch plate 504 and the second catch plate 505, and the third air cylinder 718 may be moved appropriately to adjust the level of the second catch plate 505 in order to better guide the coil R1.

The operation principle of the reel conveying system in more detail in one embodiment of the invention is as follows:

referring to fig. 1-14, a coil wound around the coil shaft 60 is required to be wound on the reel 11, or a coil produced by other equipment is drawn and wound on the reel 11 (refer to fig. 11 and 12), the coil R1 passes through the guide shaft 601 and then passes through the gap G5 between the first clamping board 504 and the second clamping board 505 of the coil jaw assembly 50, so that the coil starting end E of the coil R1 is landed on the second clamping board 505, in the process, when the coil R1 needs to be wound on the reel 11 for the first time, the coil starting end E can be drawn into the gap G5 between the first clamping board 504 and the second clamping board 505 by manual intervention, referring to fig. 14, after that, the third air cylinder expansion rod 718 extends to push the second clamping board 505, the second clamping board 505 rotates around the shaft 78, so that the second clamping board 505 is gathered towards the first clamping board 504, so that the coil starting end E is clamped by the first clamping board 504 and the second clamping board 505, waiting for the web material to be wound on the reel 11.

Referring to fig. 12, when a coil needs to be wound on the spool 11, the spool 11 is conveyed to the supporting base 591 (corresponding to the left sliding support 3-1 and the right sliding support 3-2) and the slot 40 of the spool 11 is aligned with the first clamping plate 504 and the second clamping plate 505 (this process can be realized by the motor 80 driving the spool 11 to rotate, as described in detail above), the clamping block 208 of the slot 40 extends to leave a space for the first clamping plate 504 and the second clamping plate 505 to enter the slot 40 with the coil start end E, the cylinder extension rod 503 extends to advance the first clamping plate 504 and the second clamping plate 505 clamping the coil start end E into the slot 40 of the spool 11, and then the clamping block 208 retracts into the slot 40, so as to press the coil start end E against the first side wall S1 or the second side wall S2 of the slot 40, which plays a role of fixing the coil start end E in the slot 40, it should be noted that, since the gap G1 is left between the adjacent clamping blocks 208, and the first clamping plate 504 and the second clamping plate 505 are provided with the first gap d1 and the second gap d2 facing each other, when the clamping blocks 208 are retracted into the clamping slot 40, the position of the clamping blocks 208 is just above the first gap d1 and the second gap d2, and the position of the first clamping plate 504 and the second clamping plate 505 is just at the gap G1 between the clamping blocks 208, therefore, the clamping blocks 208 only press the start end E of the coil against the first side wall S1 or the second side wall S2 of the clamping slot 40, but not press the first clamping plate 504 and the second clamping plate 505, at this time, the third air cylinder 718 is deflated, the clamping force between the first clamping plate 504 and the second clamping plate 505 disappears, or the clamping slot 40 can be designed with a certain space reserved so that the mutually clamped first clamping plate 504 and the second clamping plate 505 in the clamping slot 40 can be slightly opened to facilitate the start end E clamped by the first clamping plate 504 and the second clamping plate 505, then the cylinder extension rod 503 retracts in the opposite direction, and drives the first chuck plate 504 and the second chuck plate 505 to return, at this time, the coiled material R1 is supported by the second chuck plate 505 through the gap G5 between the first chuck plate 504 and the second chuck plate 505, the reel 11 rotates to wind the coiled material, after the reel 11 is wound to the coiled material with the required amount, the cutter is arranged in front of the first chuck plate 504 and the second chuck plate 505 to cut off the coiled material R1 between the reel 11 and the front ends of the first chuck plate 504 and the second chuck plate 505, after the coiled material R1 is cut off, the coiled material starting end E of the coiled material wound on the coiled material rotating shaft 60 is also clamped by the first chuck plate 504 and the second chuck plate 505, so as to wait for the next circulation to wind the coiled material to another reel 11. The coiled materials can be wound on different reels 11 by circulating the work, the reel 11 which is fully coiled is sent out by the left sliding support frame 3-1 and the right sliding support frame 3-2 in a sliding way, and when the reel 11 which is fully coiled on the left sliding support frame 3-1 and the right sliding support frame 3-2 is taken down, the left sliding support frame 3-1 and the right sliding support frame 3-2 wait for the next reel 11 to be supported in a circulating way.
