Description

Technical Field

[0001] This invention relates to a material pushing and blocking mechanism, and more particularly to a material pushing and blocking mechanism for an automatic cable tie tool. Background Technology

[0002] Traditionally, bulk cable ties are manually tied one by one to the products being bundled, which is inefficient and labor-intensive. In 2014, the inventor of this patent disclosed a handheld automatic cable tie tool (ZL2014103581622), and subsequently developed a series of extended products, including a fixed cable tie gun and an automatic cable tie tool for confined spaces (ZL2016100057047). These products all utilize a vibrator to sort, arrange, orient, and directionally filter the messy bulk cable ties, and to vibrate and convey them. Since the vibrator is mounted on the automatic cable tie machine's main unit, its vibration causes forced vibration of the entire main unit frame and all parts mounted on it. This results in unpredictable vibration and displacement of the cable ties in the pushing or feeding mechanism, easily leading to jamming and feeding failures. To solve the problem of unpredictable cable tie displacement caused by the vibration system, the inventor designed a pushing and blocking mechanism for the automatic cable tie tool. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of unpredictable displacement of cable ties caused by vibration in automatic strapping equipment, and to design an automatic cable tie tool with a pushing and blocking mechanism.

[0004] This invention is achieved through the following technical solution: a pushing and blocking mechanism for an automatic cable tie tool, comprising at least: a main frame, a control processor, a vibrator, a conveyor plate, a pushing mechanism, and a blocking mechanism; the control processor is mounted on the main frame; the vibrator includes at least one circular vibrator or at least one linear vibrator, the vibrator being directly mounted on the main frame or mounted on the main frame via a support plate; the conveyor plate is provided with a guide groove for guiding the cable tie head, the cable tie head can only move laterally within the guide groove of the conveyor plate but cannot rotate within the guide groove of the conveyor plate; The feeding mechanism is directly mounted on the main frame or mounted on the main frame via a support plate; the feeding mechanism includes at least: a feeding body, a feeding rod, and a guide block; the feeding body is provided with a step, the bottom surface of the step of the feeding body is abutted and aligned with the bottom surface of the guide groove of the conveyor plate, the width of the step of the feeding body is just enough to accommodate a cable tie head, the side of the step of the feeding body is used for side positioning of the cable tie head, and the feeding rod is also mounted on the bottom surface of the step of the feeding body; the guide block is fixedly mounted on the feeding body and located at one end of the cable tie tail, and the guide block is provided with longitudinal and transverse guide ramps. The cable tie tail is guided vertically and horizontally. The baffle mechanism is mounted on the main frame or via a support plate, or on the pusher body of the pusher mechanism. The baffle mechanism is located near the cable tie tail and includes at least one baffle plate capable of vertical, horizontal, or swinging motion. When the pusher rod retracts to its original position, the cable tie enters the step of the pusher body from the conveyor plate. The end of the pusher rod is in close contact with the cable tie head to prevent the cable tie from retracting. The baffle plate can block the cable tie tail with its side or press the cable tie tail against the step of the pusher body with its bottom surface to prevent the cable tie from moving freely under vibration. When or before the pusher rod pushes the cable tie, the baffle mechanism activates and releases the baffle plate from blocking or pressing the cable tie tail. The control processor controls the pusher mechanism and the baffle mechanism to work alternately in sequence.

[0005] The control processor is a programmable controller, a microcontroller, a computer, or a microchip.

[0006] The circular or linear vibrator can sort, filter, arrange, and orient the messy bulk cable ties and output them in a unique orientation. The output port of the circular vibrator is a linear guide rail, which is mainly used to limit the cable tie head. That is, the output guide rail of the circular vibrator guides the cable tie head.

[0007] The conveyor plate is mounted on the linear vibration generator, which provides power to drive the cable ties to move laterally on the conveyor plate; or a ratchet is provided below the guide groove of the conveyor plate, and the ratchet rotation drives the head of the cable ties on the conveyor plate to move laterally.

[0008] Preferably, the material blocking mechanism is designed to swing, and the lever amplification principle is used to make the working end of the material blocking plate have a fast response and stroke amplification effect. Alternatively, the baffle plate or pressure plate of the baffle mechanism is designed with steps, and the two sides of the steps respectively block the tail of the cable tie and press down the tail of the cable tie.

[0009] Preferably, the bottom surface of the pusher body and the pusher rod are arranged at a certain angle to the horizontal mounting surface on the main unit. With the horizontal plane as a reference, the bottom surface of the pusher body is higher near the tail of the cable tie than near the head. This angle is generally set between 5 and 30 degrees. Due to this angle, when the cable tie is subjected to vibration, it will also be subjected to a component of its own weight along the bottom surface of the pusher body. This will cause the cable tie to tend to move towards the head (i.e., the pusher rod end), thus reducing the tendency for it to move towards the tail. Combining this technique of setting the bottom surface of the pusher body and the pusher rod at a certain angle to the horizontal mounting surface on the main unit with the material blocking mechanism will yield better results.

[0010] When the pusher rod pushes the cable tie, in order to prevent the cable tie head from jumping up and down, an elastic pressure plate system is added to the pusher mechanism. The elastic pressure plate system includes at least a pressure plate and a spring. Under the action of the spring force, the pressure plate extends out of the front end of the pusher rod and covers the top of the cable tie head until the pressure plate is blocked by the end position blocking block. When the pusher mechanism pushes the cable tie to move on the step of the pusher body, the pressure plate can prevent the cable tie head from jumping up and down.

[0011] An end position blocking block is also provided. The end position blocking block is fixed above the guide block or the pusher body, or the end position blocking block is integrated with the guide block, or the end position blocking block is integrated with the pusher body.

[0012] The push rod of the pusher mechanism is driven by a cylinder, a pneumatic motor, or an electric motor. The baffle plate or pressure plate of the baffle mechanism is driven by a cylinder, a pneumatic motor, or an electric motor.

[0013] The beneficial effects of this invention are as follows: For automatic cable tie feeding tools with vibration feeding, this invention can prevent unpredictable displacement of the cable tie on the pushing mechanism, greatly improving the stability of cable tie feeding. For cable ties with a warped tail, especially for bent or deformed cable ties, the technical solution of this invention can effectively prevent unpredictable displacement of the cable tie and also correct the deformation of the cable tie tail.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0017] like Figure 1As shown, an automatic cable tie tool's pushing and blocking mechanism includes: a main frame 1, a control processor 2, a circular vibrator 4, a pushing mechanism 5, a blocking mechanism 3, and a conveyor plate 8; the control processor 2 is installed inside the main frame 1 (not visible in the figure), and the circular vibrator 4, the pushing mechanism 5, and the blocking mechanism 3 are respectively mounted on the main frame 1 via support plates 10; the conveyor plate 8 is provided with a guide groove for guiding the cable tie head, and the cable tie head can only move laterally within the guide groove of the conveyor plate 8. The cable ties cannot be flipped within the guide groove of the conveyor plate 8. The circular vibrator 4 can sort, filter, arrange, and orient the disordered bulk cable ties and output them in a unique orientation. The output port of the circular vibrator 4 is a linear guide rail, which guides the head of the cable tie. The linear output guide rail of the circular vibrator 4 is aligned with the guide groove of the conveyor plate 8. A linear vibration generator 81 is provided below the conveyor plate 8, which provides vibration force to the conveyor plate 8 to drive the cable ties. The material moves laterally on the conveyor plate 8; the pushing mechanism 5 includes at least: a pushing body 51, a pushing rod 52, and a guide block 54; the pushing body 51 is provided with a step, the bottom surface of the step of the pushing body 51 is aligned with the bottom surface of the guide groove of the conveyor plate 8, one end face of the conveyor plate 8 is adjacent to the step of the pushing body 51 and the one end face of the conveyor plate 8 and the step of the pushing body 51 form a groove slightly wider than the head of the cable tie; under the vibration force of the linear vibration generator 81, the conveyor plate 8 pushes the cable tie laterally. The cable tie is fed onto the step of the pusher body 51; the step width of the pusher body 51 is just wide enough to accommodate the head of a cable tie, the side of the step of the pusher body 51 is used for side positioning of the cable tie head, the pusher rod 52 is also installed on the bottom surface of the step of the pusher body 51, and when the pusher rod 52 retracts, the end of the pusher rod 52 is in close contact with the head of the cable tie 6 to prevent the cable tie 6 from retracting; the guide block 54 is fixedly installed on the pusher body 51 and located at one end of the cable tie tail, and the guide block 54 has longitudinal and transverse guide slopes ( Figure 1 (Not visible in the middle), guides the tail of the cable tie in the horizontal and vertical directions; when the push rod 52 pushes the cable tie 6, the push rod 52 and the cable tie 6 move in the groove formed by one end face of the conveyor plate 8 and the step of the push body 51, and then the cable tie is pushed into the guide block 54 which has longitudinal and transverse guide slopes (if the processing conditions permit, the guide block 54 and the push body 51 can be made as one piece); the cylinder 32 of the blocking mechanism 3 is mounted on the support plate 10, and the blocking plate fixing seat 38 of the blocking mechanism 3 is mounted on the push body 51 of the push mechanism 5 ( Figure 1 (Not visible in the middle), the material blocking mechanism 3 is located at one end near the tail of the cable tie. Example

[0018] like Figures 2 to 5 As shown, the material blocking mechanism 3 is disposed on the pushing body 51 of the pushing mechanism 5 near the end of the cable tie. The material blocking mechanism 3 includes at least one material blocking plate 35 that can swing or move up and down. The material blocking plate 35 can block the end of the cable tie with its side or press the end of the cable tie against the step of the pushing body 51 with its bottom surface to prevent the cable tie from moving. When the pushing rod 52 pushes the cable tie 6 or before it pushes the cable tie 6, the material blocking mechanism 3 is activated and releases the constraint of blocking or pressing the end of the cable tie 6.

[0019] Specifically, such as Figure 3 , Figure 4 and Figure 5 One preferred design of the baffle mechanism 3 shown includes: a cylinder mounting pin 31, a cylinder 32, a hinge pin 33, a baffle plate center pin 34, a baffle plate 35, a cylinder actuating rod 36, a connecting piece 37, and a baffle plate fixing seat 38. The baffle plate 35 is designed as an inverted L-shape. The cylinder 32 is mounted on the support plate 10 and can rotate around the cylinder mounting pin 31 fixed to the support plate 10. The cylinder actuating rod 36 is fixedly connected to the connecting piece 37. The connecting piece 37 is connected to the baffle plate 35 through the hinge pin 33. The baffle plate 35 is connected to the baffle plate fixing seat 38 through the baffle plate center pin 34. The baffle plate 35 can rotate around the cylinder mounting pin 36. The center pin 34 of the material plate rotates, and the baffle plate fixing seat 38 is fixed on the pusher body 51. The extension and retraction of the cylinder rod 36 can make the baffle plate 35 rotate around the center pin 34 of the baffle plate. Since the hinge pin 33 is close to the center pin 34 of the baffle plate, and the center pin 34 of the baffle plate is far from the working end of the baffle plate 35 that performs the baffle function (at the lower end face 353 of the baffle plate), by using the lever principle, the cylinder rod 36 only needs to push out or retract a small distance to make the working end of the baffle plate 35 that performs the baffle function produce a large displacement, and at the same time, it can make the working end of the baffle plate 35 that performs the baffle function produce a faster movement speed response than the cylinder rod 36.

[0020] Alternatively, the baffle plate 35 can be designed to move up and down or horizontally (not shown in the figure). Example

[0021] like Figure 3 , Figure 6 and Figure 7 As shown, the baffle plate 35 of the baffle mechanism 3 is designed in different forms to block the tail of the cable tie, press down the tail of the cable tie, or combine the functions of blocking and pressing.

[0022] in, Figure 3 As shown, when the baffle plate 35 swings and moves downward, the baffle plate 35 uses its side to block the tail of the cable tie 6 to prevent the cable tie 6 from moving towards the tail under the action of vibration. Figure 6 The lower end of the baffle plate 35 shown is designed with a step. When the baffle plate 35 moves downward, the side 351 of the step of the baffle plate blocks the tail of the cable tie to prevent the cable tie 6 from moving towards the tail under the action of vibration; the bottom surface 352 of the step of the baffle plate presses the tail of the cable tie 6 downward. Figure 7 As shown, when the baffle plate 35 moves downward, the lower end face 353 of the baffle plate 35 directly presses the tail of the cable tie 6 onto the step of the pusher body 51 to prevent the cable tie 6 from moving towards the tail under the action of vibration.

[0023] Figure 6 and Figure 7 The structure shown can correct deformed cable ties or cable ties with upturned tails, so that when the push rod 52 pushes the cable tie 6, it can smoothly push the cable tie 6 into the longitudinal guide slope 541 or the transverse guide slope 542 of the guide block 54. This facilitates the guide block 54 to guide the tail of the cable tie 6 and can effectively prevent the tail of the cable tie 6 from becoming unstable during the push of the push rod 52 due to the large upturned angle (avoiding the pressure angle between the upturned tail of the cable tie and the longitudinal guide slope 541 or the transverse guide slope 542 of the guide block 54 from being too large, which would cause instability and bending).

[0024] like Figure 6 and Figure 7 The structure shown uses a cylinder 32 to drive the baffle plate 35, or it can be driven by a motor.

[0025] like Figure 6 and Figure 7 The baffle plate 35 shown is configured to swing, or it can be configured to move linearly up and down or horizontally. Example

[0026] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sensor 53 is also installed below or on the side of the pusher body 51 (near the head of the cable tie 6). The conveyor plate 8 conveys the cable tie 6 onto the step of the pusher body 51. The sensor 53 detects the presence of the cable tie 6 on the step of the pusher body 51, and the baffle plate 35 is driven to swing or press down to block or press the tail of the cable tie 6. When the pusher rod 52 pushes the cable tie 6 or before pushing the cable tie 6, the baffle plate 35 must immediately retract to avoid the movement of the cable tie 6 and the pusher rod 52 to avoid interference. This is why the baffle mechanism 3 is best designed as follows: Figure 4 and Figure 5The structure is designed for rapid response, amplifying the speed and stroke of the end of the baffle plate 35. When the push rod 52 returns to its origin, the conveyor plate 8 transports the cable tie 6 onto the step of the pusher body 51. When or before the push rod 52 pushes the cable tie 6, the baffle mechanism 3 activates and releases the constraint of the baffle plate 35 on the tail of the cable tie 6 (i.e., the baffle mechanism 3 is in the exit baffle state). The control processor 2 controls the pusher mechanism 5 and the baffle mechanism 3 to work in a coordinated cycle.

[0027] If the downward pressing action of the baffle plate 35 on the tail of the cable tie 6 is not considered, the baffle plate 35 can also be designed to move horizontally; if the downward pressing action of the baffle plate 35 on the tail of the cable tie 6 is not considered, the baffle mechanism 3 blocking the cable tie does not affect the conveyor plate 8 from conveying the cable tie 6 onto the step of the pusher body 51; if the tail of the cable tie 6 is raised or deformed, if the baffle plate 35 is designed to press down on the tail of the cable tie 6, then the baffle plate 35 must be in the unblocking state during the process of the conveyor plate 8 conveying the cable tie 6 onto the step of the pusher body 51. Example

[0028] like Figure 1 and Figure 2 As shown, the pushing mechanism 5 and the blocking mechanism 3 are mounted on the main frame 1 (not shown) via a support plate 10. Figure 2 As shown, the pushing direction of the pushing mechanism 5 is at a certain angle to the mounting bottom surface of the support plate 10. Specifically, the stepped surface of the pushing body 51 and the pushing rod 52 are not parallel to the mounting bottom surface of the support plate 10, but are set to be parallel but at a certain angle V. Moreover, the stepped surface of the pushing body 51 is higher at the end near the tail of the cable tie 6 than at the end near the head of the cable tie 6. When the cable tie 6 is conveyed onto the stepped surface of the pushing body 51, the pushing rod 52... Figure 2 The origin position shown is (both the pusher cylinder 55 and the pusher rod are in the retracted state). Since the end face of the pusher rod 52 is pressed against the head of the cable tie 6, even if there is vibration, the cable tie 6 cannot move towards the pusher rod 52. However, without the presence of the baffle mechanism 3, the cable tie 6 may tend to move towards the tail of the cable tie 6 under the action of vibration. In order to avoid the cable tie 6 tending to move towards the tail of the cable tie 6 under the action of vibration, the stepped surface of the pusher body 51 and the pusher rod 52 are both set at a certain angle V with the mounting bottom surface of the support plate 10. The stepped surface of the pusher body 51 and the pusher rod 52 are aligned with the main frame 1 ( Figure 2 The mounting surface (horizontal plane) (not shown) is set at a certain angle V to prevent the cable tie 6 from moving towards the tail of the cable tie 6 under the action of vibration; the angle V is generally set between 5 and 30 degrees.

[0029] Due to the presence of the included angle V, when the cable tie 6 is subjected to vibration, it will also be subjected to a component of its own weight along the direction of the bottom surface of the step of the pusher body 51. This will cause the cable tie 6 to tend to move towards the head of the cable tie (i.e., one end of the pusher rod 52), thus reducing the tendency for the cable tie 6 to move towards the tail of the cable tie. The technique of setting the bottom surface of the step of the pusher body 51 and the pusher rod 52 at a certain angle to the horizontal mounting surface on the main unit, when combined with the material blocking mechanism 3, will have a better effect. Example

[0030] like Figure 2 and Figure 3 As shown, to prevent the cable tie 6 from jumping during the pushing process, an elastic pressure plate system 7 is also provided above the push rod 52. The elastic pressure plate system 7 includes: a pressure plate 71, a guide rod 72, a fixing sleeve 75, a spring 76, and a spring mounting limiter 74. An end position blocking block 77 is also provided above the push body 51 or the guide block 54. The end position blocking block 77 can be made integral with the push body 51 or the guide block 54. The guide rod 72 is fixedly connected to the pressure plate 71, the fixing sleeve 75 is fixed on the guide rod 72, the spring 76 is installed on the guide rod 72 and its position is limited by the spring mounting limiter 74. The spring mounting limiter 74 is fixedly connected to the push rod 52. The elastic pressure plate system 7 can move with the push rod 52. The pressure plate 71 extends out of the front end of the push rod 52 under the elastic force of the spring 76. Figure 3 As shown, when the push rod 52 pushes the cable tie 6 to move on the step of the push body 51, the pressure plate 71 extends out of the front end of the push rod 52 under the elastic force of the spring 76 to press down the head of the cable tie 6 to prevent the cable tie head from jumping. Figure 2 The diagram shows the state where, when the pressure plate 71 is subjected to external force, the pressure plate 71, guide rod 72, fixing sleeve 75, and other parts move to the left and compress the spring 76. (When the push rod 52 pushes the cable tie 6 forward, and the end of the pressure plate 71 or guide rod 72 touches the end position blocking block 77, a compression occurs.) Figure 2 (The spring 76 in the middle is in a compressed state).

[0031] If processing costs are not considered, all parts in the elastic pressure plate system 7 that are "fixed" connected can be made into one piece. For example, "the spring mounting limiter 74 is fixedly connected to the push rod 52" means that the spring mounting limiter 74 and the push rod 52 can be made into one piece; "the guide rod 72 is fixedly connected to the pressure plate 71, and the fixing sleeve 75 is fixed on the guide rod 72" means that the guide rod 72 and the pressure plate 71 can be made into one piece, and the fixing sleeve 75 can also be made into one piece with the guide rod 72. Such merging is an option, but not the optimal option, as the merging method will result in slightly higher processing, assembly, and debugging costs.

[0032] The above description of the elastic pressure plate system 7 can be summarized as follows: the elastic pressure plate system 7 includes at least a pressure plate 71 and a spring 76; when the push rod 52 pushes the cable tie 6 to move on the step of the push body 51, the pressure plate 71 extends out of the front end of the push rod 52 under the elastic force of the spring 76 to press down on the head of the cable tie 6 to prevent the cable tie head from jumping.

[0033] To allow the guide rod 72 to slide smoothly relative to the spring mounting limit member 74 and the push rod 52, a linear bearing 73 can also be provided. The linear bearing 73 is fixedly connected to the spring mounting limit member 74 and the push rod 52, and the guide rod 72 can slide smoothly in the inner hole of the linear bearing 73. Example

[0034] like Figure 8 As shown, parts such as the main frame 1 have been removed. Figure 8 In the process, the circular vibrator 4 sorts and arranges the cable ties and conveys them to the conveyor plate 8. The conveyor plate 8 is equipped with a ratchet drive system or a linear vibration generator 81. The ratchet drive system includes at least a motor 93 and a ratchet 94. The ratchet 94 is installed below the groove of the conveyor plate 8 and the tip of the ratchet tooth of the ratchet 94 protrudes from the bottom surface of the groove of the conveyor plate 8. The motor 93 drives the ratchet 94 to rotate. The friction between the tip of the ratchet tooth of the ratchet 94 and the head of the cable tie drives the cable tie to move in the groove of the conveyor plate 8 and then conveys the cable ties one by one to the step of the pusher body 51.

[0035] like Figure 9 As shown, parts such as the main frame 1 have been removed. Figure 9 In the process, the linear vibrator 41 sorts and arranges the cable ties and conveys them to the conveyor plate 8. The conveyor plate 8 is equipped with a ratchet drive system or a linear vibration generator 81. The ratchet drive system includes at least a motor 93 and a ratchet 94. The ratchet 94 is installed below the groove of the conveyor plate 8 and the tip of the ratchet tooth of the ratchet 94 protrudes from the bottom surface of the groove of the conveyor plate 8. The motor 93 drives the ratchet 94 to rotate. The friction between the tip of the ratchet tooth of the ratchet 94 and the head of the cable tie drives the cable tie to move in the groove of the conveyor plate 8 and then conveys the cable ties one by one to the step of the pusher body 51.
