Description

Technical Field

[0001] The invention relates to an automatic material cutting device, in particular to an automatic material cutting device for a one-piece cable tie. Background Art

[0002] Traditionally, cable ties are supplied in bulk packaging. When used, people pick up bulk cable ties one by one by hand, which is easy to deform. The deformation problem of bulk cable ties poses a great challenge to cable tie automation. In order to more reliably realize the automation of cable ties, cable ties are made into one-piece type, and a device or machine is required to cut the one-piece cable ties and transport the cut cable ties to the automatic cable tie tool; in addition, due to different customer needs, cable ties sold on the market have different quantities of packages such as 50 per package, 100 per package, 500 per package, and 1000 per package. Traditionally, these packages are counted manually one by one. This method is inefficient and prone to errors. In order to realize the automatic counting or automatic bundling operation of the quantitative packaging of one-piece cable ties, I have designed an automatic cutting and feeding device for one-piece cable ties. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic cutting and feeding device for one-piece cable ties designed for automatic quantitative packaging of cable ties or automatic bundling of cable ties.

[0004] The present invention is realized through the following technical scheme: an automatic cutting and feeding device for a one-piece cable tie, comprising: a main frame, a cable tie bracket, a guide plate, a guide arc, a control processor, a cable tie pressure plate, a blade, a blade seat, a dividing roller, a dividing mechanism, a bracket plate, a pusher block, a pusher cylinder, a valve seat, a valve, a valve cylinder, and a square-section feeding tube. The dividing mechanism is capable of making the dividing roller perform intermittent dividing motion. The dividing mechanism includes a motor, a sensor, a sensor sheet, a gear, and a center gear. Its structure is: the guide arc, cable tie pressure plate, a blade, a blade seat, a dividing roller, a dividing mechanism, a pusher block, a pusher cylinder, a valve seat, a valve, and a valve cylinder are all installed on the bracket plate to form a sub-assembly. The guide plate, the guide arc, and the cable tie pressure plate are connected in sequence. The blade, The blade seat is installed on the cable tie pressure plate, and the indexing roller is installed on the bracket plate. The indexing roller is cylindrical and has a plurality of axial grooves on the periphery that are parallel to the axis of the indexing roller and evenly distributed in the circumferential direction. The pitch of adjacent axial grooves of the indexing roller is equal to the pitch of the connected cable tie. The indexing mechanism is composed of a motor, a sensor, a sensor sheet, a gear, and a central gear. The central gear is coaxially connected to the indexing roller. The power of the motor is reduced by the gear and drives the indexing roller through the central gear. The sensor sheet is coaxially connected to the motor. The motor shaft The sensor senses once during one rotation, and the indexing roller rotates one axial groove pitch. The axis center line of the arc surface of the cable tie pressure plate coincides with the axis center line of the indexing roller. The cable tie pressure plate is fixed, and the arc surface of the cable tie pressure plate cooperates with the circumferential surface of the indexing roller and leaves a movement interval. The arc surface of the cable tie pressure plate has arc convex ribs that cooperate with the circumferential groove of the indexing roller in the circumferential direction. The arc convex ribs of the cable tie pressure plate press the cable tie and make the cable tie close to the bottom surface of the axial groove of the indexing roller. The blade is installed on the cable tie pressure plate through the blade seat, and the blade is close to the The end face of the indexing roller, the blade is used to cut and separate the cable tie from the rib plate of the connected cable tie, the push block is aligned with one of the axial grooves of the indexing roller, the valve seat has a square cross-section hole, the square hole in the valve seat is also aligned with the axial groove of the indexing roller and the push block, one end of the valve seat is connected to the square cross-section feeding pipe, the valve seat is also equipped with a valve for cutting off or opening the square hole channel in the valve seat, the valve or the valve seat has a small hole connected to the compressed air, and the control processor is a programmable controller or a single-chip microcomputer or a computer or a microchip;Its working principle is: the cable tie bracket is used to support the wound one-piece cable tie, the one-piece cable tie is guided to transition to the indexing roller through the guide plate and the guide arc, the cable ties of the one-piece cable tie are embedded in the axial groove of the indexing roller one by one, the pushing block exits the axial groove of the indexing roller under the action of the pushing cylinder or the belt driven by the motor to allow the indexing roller to rotate, the indexing mechanism drives the indexing roller to make intermittent indexing rotation and rotates one axial groove pitch each time, the rotation of the indexing roller drives the one-piece cable tie to be fed in, The blade cuts and separates the cable tie from the rib plate of the connected cable tie. When the cut cable tie is brought to the axial groove position aligned with the push block by the indexing roller, the push block pushes the cable tie through the valve position into the square cross-section feeding pipe under the action of the push cylinder or the belt driven by the motor. When the push block completes pushing and retreats, the valve is closed, and the compressed air pushes the cable tie in the square cross-section feeding pipe to the terminal of the automatic cable tie tool. The control processor controls the indexing mechanism, the push block, the valve and the compressed air to perform work in sequence. ;

[0005] The aforementioned structure is based on the situation of feeding out one cable tie each time and adopts a similar working principle. If two or more cable ties are to be fed out each time, then: two or more pusher blocks, two or more valve seat channels, two or more square cross-section feed pipes, and indexing rollers are used to rotate two or more axial groove pitches each time, and two or more cable ties are pushed out each time, so that an automatic cutting and feeding device can be used in conjunction with two or more automatic cable tie tools.

[0006] The automatic cutting and feeding device for one-piece cable ties can be used in conjunction with an automatic cable tie tool, and can also be used for automatic counting of quantitative packaging of cable ties. The use of the valve seat, valve, and square-section feeding tube is based on: an automatic cutting and feeding device for one-piece cable ties is used in conjunction with an automatic cable tie tool. If the automatic cutting and feeding device for one-piece cable ties is used for automatic counting of quantitative packaging of cable ties, the valve seat, valve, and square-section feeding tube can be cancelled, and the pushing block pushes the cable tie out and drops it into the receiving container, or The valve seat, valve and square-section feeding tube are retained, the push block pushes the cable tie into the valve, and the compressed air blows the cable tie out of the square-section feeding tube and drops it into the receiving container. The control processor automatically calculates the number of axial grooves rotated by the indexing roller or calculates that the cable ties pushed out by the push block reach a set number and then enters the next working cycle. Similarly, by adopting two or more push blocks and allowing the indexing roller to rotate two or more axial groove pitches each time, two or more cable ties can be pushed out each time, thereby improving the efficiency of automatic packaging counting.

[0007] The aforementioned blade is fixed on the cable tie pressure plate and remains stationary, and the rotation of the indexing roller drives the one-piece cable tie and the blade to cut and separate the cable tie from the rib plate of the one-piece cable tie, or a wedge-slider cutting mechanism is designed, and the blade is fixedly connected to the slider, and the wedge is fixed to the push block, and when the push block slides and pushes the material, the wedge pushes the follower roller, so that the slider and the blade move in the radial direction of the indexing roller to cut off the rib plate of the one-piece cable tie; the one-piece cable tie has different designs of one rib plate or two rib plates, and accordingly, one blade or two blades can be designed.

[0008] The axial groove of the indexing roller is designed according to the width of the head of the cable tie. The width of the tail of the cable tie is narrower. When the indexing roller rotates, the tail of the cable tie will be twisted. In order to make the head and tail of the cable tie move synchronously, an auxiliary synchronization mechanism is designed, that is, power is drawn from the indexing roller shaft, accelerated by two stages of gears, and the auxiliary feeding wheel 52 and the pressing roller are used to press the rib plate of the one-piece cable tie. When the indexing roller rotates one axial groove pitch, the arc length of the outer circumference of the auxiliary feeding wheel 52 is also equal to one pitch.

[0009] As an alternative: the indexing mechanism may be composed of a positioning wedge or a ratchet driven by pneumatic or electric means; the push cylinder may be driven by a belt or chain driven by a motor to drag the push block.

[0010] The blade and blade seat are fixed on the cable tie pressure plate, and the cable tie pressure plate can be installed on the bracket plate by a hinge, and the cable tie pressure plate can be flipped around the hinge; or the cable tie pressure plate can be quickly removed from the bracket plate, and a quick-locking pressure plate or an eccentric pressure plate locks the cable tie pressure plate and fixes it to the bracket plate. The cable tie pressure plate and the bracket plate are designed to be quickly flipped or quickly disassembled to facilitate quick processing of cable tie jams.

[0011] The beneficial effects of the present invention are:

[0012] It can be used for automatic counting of quantitative packaging of cable ties, and can also be used in conjunction with automatic cable tie tools to achieve automatic bundling operations;

[0013] Compared with manual work, the efficiency is greatly improved;

Implementation

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. Example

[0037] like Figures 1 to 24As shown, an automatic cutting and feeding device for a one-piece cable tie comprises: a main frame 2, a cable tie bracket 1, a guide plate 3, a guide arc 5, a control processor 4, Cable tie pressing plate 8, blade 6, blade seat 7, indexing roller 15, indexing mechanism 30, bracket plate 14, pusher block 9, pusher cylinder 10, valve seat 16, valve 17, valve cylinder 18, square cross-section feeding tube 19; the indexing mechanism 30 is capable of making the indexing roller 15 perform intermittent indexing motion, and the indexing mechanism 30 is composed of a motor 31, a sensor 34, a gear 32, a center gear 33, and a sensor sheet 35. The center gear 33 is coaxially fixedly connected to the indexing roller 15, and the sensor sheet 35 is coaxially fixedly connected to the motor 31. The power of the motor 31 is transmitted through multiple stages of the gear 32 to drive the center gear 33 and the indexing roller 15. Every time the motor 31 rotates one turn, the indexing roller 15 rotates one axial groove pitch, and the sensor 34 senses once.

[0038] The cable tie bracket 1 is used to support the wound one-piece cable tie 60, and the one-piece cable tie 60 is guided to transition to the indexing roller 15 through the guide plate 3 and the guide arc 5. The indexing roller 15 is cylindrical and has a plurality of axial grooves on the periphery that are parallel to the axis of the indexing roller 15 and evenly distributed in the circumferential direction. The pitch of the adjacent axial grooves of the indexing roller 15 is equal to the pitch of the one-piece cable tie 60. The cable ties 61 of the one-piece cable tie 60 are embedded in the axial grooves of the indexing roller 15 one by one. The indexing roller 15 is installed on the bracket plate 14. The indexing mechanism 30 drives the indexing roller 15 to perform intermittent indexing rotation and rotates one axial groove pitch each time. The cable tie pressing plate 8 has a The cable tie pressing plate 8 is fixed, and the arc surface of the cable tie pressing plate 8 matches the circumferential surface of the indexing roller 15 and leaves a movement interval. The arc surface of the cable tie pressing plate 8 has an arc convex rib 81 that matches the circumferential groove 151 of the indexing roller 15 in the circumferential direction. The arc convex rib 81 on the arc surface of the cable tie pressing plate 8 presses the cable tie 61 and makes the cable tie 61 close to the bottom surface of the axial groove of the indexing roller 15. The blade 6 is installed on the cable tie pressing plate 8 through the blade seat 7 to cut and separate the cable tie 61 from the rib plate 62 of the conjoined cable tie 60. The push block 9 is aligned with one of the axial grooves of the indexing roller 15. The valve seat 16 has a square cross-section hole, and the square hole in the valve seat 16 is also aligned with the axial groove of the indexing roller 15 and the pusher block. One end of the valve seat 16 is connected to the square cross-section feeding pipe 19. The valve seat 16 is also equipped with a valve 17 for cutting off or opening the square hole channel in the valve seat 16. The valve 17 or the valve seat 16 has a small hole connected to the compressed air. The pusher block 9 withdraws from the axial groove of the indexing roller 15 under the driving action of the push cylinder 10 or the belt driven by the motor to allow the indexing roller 15 to rotate. The rotation of the indexing roller 15 drives the conjoined cable tie 60 to be fed in, and the blade 6 connects the cable tie 61 with the ribs of the conjoined cable tie 60. The plates are cut and separated, and when the cut cable tie 61 is brought by the indexing roller 15 to the axial groove position aligned with the pushing block, the pushing block 9 pushes the cable tie 61 through the valve 17 position into the square-section feeding pipe 19 under the action of the pushing cylinder 10 or the motor-driven belt. When the pushing block 9 completes pushing and retreats, the valve 17 is closed, and the compressed air pushes the cable tie 61 in the square-section feeding pipe 19 to the automatic cable tie tool terminal. The control processor 4 controls the indexing mechanism 30, the pushing block 9, the valve 17 and the compressed air to perform work in sequence. The control processor 4 is a PLC, or a single-chip microcomputer, or a CPU or computer with processing control functions. Example

[0039] The structure described in the first embodiment is based on the situation that one cable tie 61 is fed out each time, such as Fig. 9 , Fig.10 , Fig.11 If two or more cable ties 61 are to be delivered each time, then: two or more pusher blocks 9, two or more valve seat channels, two or more square cross-section feed pipes 19, and indexing rollers 15 are used to rotate two or more axial groove pitches each time, and two or more cable ties 61 are pushed out each time, so that an automatic cutting and feeding device can be used in conjunction with two or more automatic cable tie tools. Example

[0040] The automatic cutting and feeding device for one-piece cable ties can be used in conjunction with an automatic cable tie tool, and can also be used for automatic counting of quantitative packaging of cable ties, such as Fig. 9 , Fig.10 , Fig.11 In the embodiment, the valve seat 16, valve 17 and square-section feeding tube 19 are configured based on: an automatic cutting and feeding device for one-piece cable ties is used in conjunction with an automatic cable tie tool. If the automatic cutting and feeding device for one-piece cable ties is used for automatic counting of quantitative packaging of cable ties, the valve seat 16, valve 17 and square-section feeding tube 19 are not required. The push block 9 pushes out the cable tie 61 and drops it into the receiving container. The control processor 4 automatically calculates the number of axial grooves that the indexing roller 15 has rotated or calculates that the cable tie 61 pushed out by the push block 9 reaches a set number and enters the next working cycle. Similarly, by adopting two or more push blocks 9 and allowing the indexing roller 15 to rotate two or more axial groove pitches each time, two or more cable ties 61 can be pushed out each time, thereby improving the efficiency of automatic packaging and counting of cable ties. Example

[0041] The aforementioned blade 6 is fixed on the cable tie pressing plate 8 and is stationary. The indexing roller 15 rotates to drive the combined cable tie 60 and the blade 6 to cut and separate the cable tie 61 from the rib plate 62 of the combined cable tie. Fig.16 , Fig.17 , Fig.18 , Fig.19 As shown in: The inclined wedge-slider cutting mechanism 40 is designed, including: an inclined wedge 41, a slider 42, a follower roller 43, a slider seat 44 and a blade 6, the blade 6 is fixedly connected to the slider 42, the inclined wedge 41 is fixed together with the pusher block 9, when the pusher block 9 slides to push the material, the inclined wedge 41 acts to push the follower roller 43, so that the slider 42 and the blade 6 slide in the slider seat 44, and move in the radial direction of the indexing roller 15 to cut off the rib plate 62 of the combined cable tie 60; as shown in Fig.23 , Fig.24 As shown, the integrated cable tie 60 has one rib plate 62 or two rib plates 62 of different designs, and correspondingly, one blade 6 or two blades 6 can be designed. Example

[0042] The axial groove of the indexing roller 15 is designed according to the width of the head of the cable tie 61. The width of the tail of the cable tie 61 is narrower. When the indexing roller 15 rotates, the tail of the cable tie 61 will be twisted. Fig. 20 , Fig.21 , Fig. 22 As shown, in order to make the head and tail of the cable tie 61 move synchronously, an auxiliary synchronization mechanism 50 is designed, including: a (synchronous) gear 51, an auxiliary feeding wheel 52, and a pressure roller 54, that is, the power is drawn from the indexing roller 15, and the power of the indexing roller 15 is transmitted to the auxiliary feeding wheel 52 after being accelerated by the two-stage (synchronous) gear 51. The pressure roller 54 presses the rib plate 62 of the one-piece cable tie 60 tightly against the circumference of the auxiliary feeding wheel 52, so that the rib plate 62 of the one-piece cable tie 60 and the auxiliary feeding wheel 52 move synchronously. When the indexing roller 15 rotates one axial groove pitch, the arc length of the outer circumference of the auxiliary feeding wheel 52 is also equal to one axial groove pitch of the indexing roller 15, and the rib plate 62 at the tail of the one-piece cable tie 60 also synchronously passes one axial groove pitch of the indexing roller 15. Example

[0043] like Figure 7 , Figure 8 As shown, as an alternative: the indexing mechanism 30 is replaced by a (push-lock) indexing mechanism 70, which is composed of an electrically or pneumatically driven positioning wedge 71, a ratchet 72, and a indexing plate 73. The indexing plate 73 is coaxially fixedly connected to the indexing roller 15, the ratchet 72 pushes the indexing plate 73 to rotate, and the positioning wedge 71 locks the indexing plate 73; as shown Figure 1 , Figure 3 As shown, the push cylinder 10 can be replaced by a belt or chain driven by a motor to drag the push block 9; Fig. 9 , Fig.10 , Fig.11 As shown, the valve 17 is either pneumatically driven or electrically driven. Example

[0044] like Fig. 9 As shown, the blade 6 and the blade seat 7 are fixed on the cable tie pressing plate 8, and the cable tie pressing plate 8 can be mounted on the bracket plate 14 by a hinge, as shown in FIG. Fig.10 As shown, the strap pressing plate 8 can be flipped around the hinge; Fig.11 , Fig.12 , Fig.13 , Fig.16 As shown, the cable tie pressing plate 8 can be quickly and completely disassembled from the bracket plate 14, and the cable tie pressing plate 8 can be locked and fixedly connected to the bracket plate 14 by using a quick-locking pressing plate 21 or an eccentric pressing plate 23 or an eccentric cam.
