Description

TECHNICAL FIELD

[0001] The present application relates to a part separating device, in particular to a device for separating parts from a part strip containing a plurality of parts. BACKGROUND

[0002] Parts often used in industrial production are provided in the form of a part strip containing a plurality of parts when delivered. For example, plastic rivets which are widely used in the industrial production of automobiles are usually delivered from a rivet manufacturer in the form of a plastic rivet strip, and the user has to separate the rivets from the rivet strip before use.

[0003] In the prior art, the user usually first unrolls the rivet strip, and then cuts or chops off the rivets from the rivet strip with scissors or other cutters in a manual manner. This method is time-consuming and laborious, and cannot meet the increasingly accelerated production requirements. SUMMARY

[0004] The present application aims to provide a part separating device which is simple in structure and can continuously separate parts from a part strip.

[0005] The object is achieved by a part separating device for separating parts from a part strip, the part strip having two parallel edge strips, the parts being arranged in a column between the two edge strips and connected to the two edge strips respectively, the part separating device comprising: a workbench; a cutting device mounted on the workbench, the cutting device comprising an upper cutter set and a lower cutter set, the upper cutter set comprising two cutting wheels, the two cutting wheels each having a cutting edge extending in a circumferential direction on an outer periphery thereof, the two cutting wheels of the upper cutter set and two longitudinal cutting knives of the lower cutter set cooperating to cut the part strip so as to separate the parts; and a guide device for guiding the part strip into the cutting device so that the part strip can be correctly cut in the cutting device, the upper cutter set further comprising two knurl wheels, the two knurl wheels being arranged concentrically with the two cutting wheels on the same rotating shaft, the two knurl wheels being non-rotatable relative to the two cutting wheels, the two knurl wheels being arranged on outer sides of the two cutting wheels away from each other respectively, the knurl wheels having a diameter smaller than that of the cutting wheels, during cutting, the two edge strips of the part strip being clamped between the two knurl wheels of the upper cutter set and the lower cutter set respectively.

[0006] The present application is based on the idea that continuous pulling (also referred to as dragging) and cutting of a part strip can be achieved simultaneously by arranging or integrating knurl wheels of the upper knife set without relative rotation on the cutting wheels of the upper knife set and by the cooperation of the upper knife set with the lower knife set. Specifically, during cutting, two edges of the part strip are clamped between the knurl wheels of the upper knife set and the lower knife set, respectively, and the cutting wheels and the knurl wheels of the upper knife set rotate together, so that the part strip is continuously pulled forward by the cooperation of the knurl wheels and the lower knife set while being cut by the cooperation of the cutting wheels and the lower knife set. This significantly improves work efficiency. The part separating device of the present application achieves simultaneous pulling and cutting of a part strip with a simple structure.

[0007] The part separating device is easy to use and has high production efficiency, and can separate 300 to 600 parts per minute. In addition, the part separating device can be switched between manual and automatic operation modes and is suitable for extracting parts of different sizes.

[0008] According to a preferred embodiment, two bearings rotatable about the same rotation axis are arranged on the inner sides of the two longitudinal cutting knives of the lower knife set facing each other, and the two bearings cooperate with the two knurl wheels of the upper knife set, respectively, to clamp the two edges of the part strip. It is particularly preferred that the rotation axis of the bearings is arranged parallel to the rotation axis of the cutting wheels and directly below the rotation axis of the cutting wheels. By arranging bearings cooperating with the knurl wheels, the pulling of the part strip becomes smoother, and the part strip can be prevented from breaking when pulled without bearings.

[0009] According to a preferred embodiment, the part separating device further comprises an adjusting device for adjusting the distance between the two longitudinal cutting knives of the lower knife set to adapt to cutting part strips of different widths. By arranging the adjusting device, cutting of part strips of different widths can be achieved by adjusting only the distance between the longitudinal cutting knives, without having to replace the entire lower knife set. Accordingly, the upper knife set can be replaced in order to cut part strips of different widths. It is particularly preferred that the upper knife set can also be provided with an adjusting device for adjusting the distance between the two cutting wheels to adapt to cutting part strips of different widths.

[0010] According to a preferred embodiment, the guide device comprises a coarse guide comprising a first groove gradually narrowing from upstream to downstream, and the overall shape of the coarse guide conforms to the shape of the expanded part strip. The gradually narrowing design of the coarse guide makes it easy to guide the part strip.

[0011] According to a preferred embodiment, the guiding device further comprises a fine guiding element connected to the downstream end of the coarse guiding element, the fine guiding element comprising two portions spaced apart from each other, the fine guiding element defining a second groove, the shape of the cross section of the second groove matching the profile of the cross section of the part strip, so that the part strip can be precisely positioned in and passed through the fine guiding element. By matching the shape of the cross section of the second groove with the profile of the cross section of the part strip, the part strip is precisely positioned in that the part strip cannot be pushed up and down or left and right in the fine guiding element. Additionally, in order to guide part strips of different widths, adjustment means for adjusting the spacing between the two portions of the fine guiding element of the guiding device can also be provided. When loading the part separating device, the operator only needs to put the part strip onto the coarse guiding element and then push the part strip gently, the part strip can enter into the fine guiding element along the first groove of the coarse guiding element which is gradually narrowed.

[0012] According to a preferred embodiment, the two cutting wheels and the two knurling wheels are configured to be integrated. According to another preferred embodiment, one of the two cutting wheels and one of the two knurling wheels are configured to be integrated and the other of the two cutting wheels and the other of the two knurling wheels are configured to be integrated, so that the spacing between the two integrations can be adjusted to be suitable for cutting part strips of different widths. By the integrated design, the knurling wheels and the cutting wheels will not come loose even after a long time of operation, which reduces the failure rate and improves the production efficiency.

[0013] According to a preferred embodiment, the lower knife set and the fine guiding element are configured to be integrated. This reduces the number of components and simplifies the adjustment of the positioning fit between the lower knife set and the fine guiding element.

[0014] According to a preferred embodiment, the part separating device further comprises a cutting device downstream of the cutting device, the cutting device having a first rotating wheel and a second rotating wheel with a cutting knife, the cutting device being used to cut the two edge strips of the part strip remaining after the parts are separated by the cooperation of the first rotating wheel and the second rotating wheel, so as to facilitate the collection of edge strip waste.

[0015] According to a preferred embodiment, the workbench is mounted on a cabinet for supporting the workbench, a first proximity sensor is provided on the cabinet door of the cabinet, the first proximity sensor is used to detect the opening and closing state of the cabinet door, so as to prevent the part separating device from working in a state that the cutting knife is exposed. If the first proximity sensor detects that the cabinet door is opened when the device is running, the power supply is automatically cut off, so that the power output of the motor is cut off, which improves the production safety.

[0016] According to a preferred embodiment, a support is fixedly mounted on the workbench, the rotating shaft is supported on the support, and the rotating shaft is driven by means of an electric motor or by means of a manually operated device which can be engaged to the rotating shaft.

[0017] According to a preferred embodiment, a second proximity sensor is provided on the manually operated device, the second proximity sensor being used to detect whether the manually operated device is in contact with the rotating shaft, in order to distinguish between a manual mode and an automatic mode of the part separating device, in order to control the engagement and disengagement of the clutch at the motor end.

[0018] According to a preferred embodiment, the manually operated device comprises a return spring, so that the manually operated device remains disengaged from the rotating shaft in the unoperated state. This ensures that the manually operated device can only be engaged to the rotating shaft when the manually operated device is pressed in the direction of the upper knife set, which reduces the risk of accidental engagement of the manually operated device with the cutting device due to a false touch, and thus increases the production efficiency.

[0019] According to a preferred embodiment, the workbench comprises a longitudinal slit through which the separated part and / or the two remaining edge strips of the part strip can fall after the part has been separated, in order to facilitate the collection.

[0020] According to a preferred embodiment, a part output slot for guiding the separated part and an edge strip output slot for guiding the two remaining edge strips are respectively provided below the longitudinal slit, in order to precisely guide the separated part and the remaining edge strips into different collection devices, respectively.

[0021] According to a preferred embodiment, a safety cover is provided outside the cutting device, the safety cover being fixed to the workbench and being used to isolate the cutting device, in order to prevent the part separating device from being operated in a state in which the cutting knives are exposed. This improves the production safety. Preferably, the safety cover can be transparent. BRIEF DESCRIPTION OF DRAWINGS

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments of the present application. It is self-evident that the described embodiments are only some of the embodiments of the present application, but not all embodiments of the present application. The description of these embodiments does not constitute a limitation on the protection scope of the present application.

[0039] It should be noted that the positions such as upper, lower, lateral and the like selected in the description refer to the directly described and shown drawings and are transferred to new positions in the meaning when the positions are changed.

[0040] In Figure 1 ​​A rivet tape 100 is shown, which comprises two parallel edge strips 102, a plurality of plastic rivets 101 and two connecting parts 103 between each rivet 101 and the two edge strips 102, one end of each connecting part 103 being integrated with the adjacent edge strip 102 and the other end being integrated with the rivet, the two connecting parts 103 being located at the diametrically opposite ends of each rivet. The rivet tape 100 is usually wound into a rivet tape roll for easy transportation and storage.

[0041] In the prior art, the user usually first unwinds the rivet tape roll and then manually cuts or chops off the connecting parts 103 with scissors or other knives to separate the rivets 101 from the rivet tape 100. This method is time-consuming and laborious and cannot meet the increasingly fast production requirements.

[0042] In Figure 2 and Figure 3 a perspective view of a part separating device 1 according to the present application is shown. The part separating device 1 mainly has a workbench 9, a guiding device 14, a cutting device 15 and an electrical box 2 containing an electrical system. The workbench 9 can be mounted on a cabinet 4 for supporting the workbench 9. The cabinet 4 can have wheels 10 and a cabinet door 11. In the cabinet 4, there are placed a rivet bucket 7 for collecting separated rivets and an edge strip bucket 5 for collecting edge strips cut into small pieces, the rivet bucket 7 and the edge strip bucket 5 cooperating with a rivet output slot 13 and an edge strip output slot 12 of the part separating device 1, respectively, arranged below the workbench 9. The cabinet door 11 can be transparent so as to observe whether the edge strip bucket 5 and the rivet bucket 7 in the cabinet 4 are filled up in time for replacement. In Figure 2 it can be clearly seen that outside the cutting device 15, there is provided a safety cover 3 fixed on the workbench 9 and arranged for isolating the cutting device of the part separating device 1 from working in a state that the cutting knife is exposed. The safety cover 3 can preferably be made of transparent material, such as transparent plastic. The safety cover 3 has an opening 8 on one side for the guiding device 15 to pass through.

[0043] In Figure 2 a working state of the part separating device 1 is shown, in which the cabinet door 11 is closed, and in Figure 2 the safety cover 3 is shown. In Figure 3 a stop state of the part separating device 1 is shown, in which the cabinet door 11 is opened, and in Figure 3 the safety cover 3 is not shown. On the workbench 9, there are provided two buttons 6', 6" for starting and stopping the part separating device 1.

[0044] The structure of the main parts of the component separating apparatus 1 of the present application will be described below in detail. "Longitudinal direction" used in this specification corresponds to the length direction of the rivet tape, "transverse direction" corresponds to the width direction of the rivet tape perpendicular to the longitudinal direction, and "upstream" and "downstream" are in terms of the direction of feeding the rivet tape in the component separating apparatus, so that, for example, "upstream" corresponds to the right side and "downstream" corresponds to the left side. Figure 4

[0045] The main parts of the component separating apparatus 1 are shown in longitudinal cross-sectional view and transverse cross-sectional view in Figs. 1 and 2, respectively, and the work table 9, the guide device 14 and the cutting device 15 are shown in detail. The rivet tape 100 is guided to the cutting device 15 via the guide device 14 to be cut, and the separated rivets and the remaining edge strip after the cutting are collected in different collecting devices, which will be described in detail below. Figure 4 Figure 5 The guide device 14 has a coarse guide 17 and a fine guide 18 connected to the downstream end of the coarse guide 17.

[0046] The coarse guide 17 of the guide device 14 is shown in Fig. 3. The coarse guide 17 is arc-shaped as a whole so as to conform to the shape of the rivet tape roll just after being unwound (see Fig. 4), and thus the rivet tape 100 can be fitted on the coarse guide 17. As shown in Fig. 3, the coarse guide 17 has a recess 19 for positioning the rivet tape 100. The recess 19 is gradually narrowed from upstream to downstream. The coarse guide 17 further has a connecting portion 20 at its downstream end for connecting with the fine guide 18, so that the recess 19 of the coarse guide 17 communicates with the recess 21 of the fine guide 18, and the width of the recess 19 of the coarse guide 17 at its downstream end is the same as the width of the recess 21 of the fine guide 18.

[0047] As shown in Figs. 5 and 6, the cutting device 15 is mounted on the work table 9, and the cutting device 15 includes an upper knife set 23 and a lower knife set 24. The upper knife set 23 includes two cutting wheels 25', 25" of the same construction and two knurling wheels 26', 26" of the same construction. The two cutting wheels 25', 25" have knife edges 31, 31' extending in the circumferential direction on their outer peripheries, respectively (see Fig. 7). Figure 6 Figure 4 The lower knife set 24 includes two cutting wheels 27', 27" of the same construction and two knurling wheels 28', 28" of the same construction. The two cutting wheels 27', 27" have knife edges 32, 32' extending in the circumferential direction on their outer peripheries, respectively (see Fig. 8). The two knurling wheels 28', 28" have knurling edges 33, 33' extending in the circumferential direction on their outer peripheries, respectively (see Fig. 9). Figure 6

[0048] Figure 4 Figure 5 Figure 11 ​​​​​​​). The two knurling wheels 26', 26" are arranged concentrically with the two cutting wheels 25', 25" on the same rotating shaft 30, and the two knurling wheels 26', 26" are not rotatable relative to the two cutting wheels 25', 25". The two knurling wheels 26', 26" are arranged on the outer sides of the two cutting wheels 25', 25" respectively, which are away from each other. The diameters of the knurling wheels 26', 26" are smaller than the diameters of the cutting wheels 25', 25". Preferably, the two cutting wheels 25', 25" and the two knurling wheels 26', 26" are all integrated, or one of the two cutting wheels 25' and one of the two knurling wheels 26' are integrated, and the other of the two cutting wheels 25" and the other of the two knurling wheels 26" are integrated. The lower knife set 24 comprises two longitudinal cutting knives 27', 27", which are arranged at intervals and symmetrically. The two longitudinal cutting knives 27', 27" of the lower knife set 24 respectively have longitudinally extending cutting edges 32', 32". During cutting, the two edge strips 102 of the rivet tape 100 are clamped between the two knurling wheels 26', 26" of the upper knife set 23 and the lower knife set 24 respectively, and the two cutting wheels 25', 25" of the upper knife set 23 and the two longitudinal cutting knives 27', 27" of the lower knife set 24 cooperate with each other to cut the connecting part 103 of the rivet tape 100, so as to separate the rivet 101 from the edge strip 102.

[0049] Preferably, two bearings 33', 33" rotatable about the same rotating axis are arranged on the inner sides of the two longitudinal cutting knives 27', 27" of the lower knife set 24 facing each other, and the two bearings 33', 33" cooperate with the two knurling wheels 26', 26" of the upper knife set respectively. The outermost points of the bearings 33', 33" are slightly higher than or at least flush with the cutting edges 32', 32" of the lower knife set 24. Preferably, the rotating axes of the bearings 33', 33" are arranged parallel to and directly below the rotating axes of the cutting wheels 25', 25". In this case, during cutting, the two edge strips 102 of the rivet tape 100 are clamped between the two knurling wheels 26', 26" of the upper knife set 23 and the bearings 33', 33" of the lower knife set 24 respectively, and the two cutting wheels 25', 25" of the upper knife set 23 and the two longitudinal cutting knives 27', 27" of the lower knife set 24 cooperate with each other to cut the connecting part 103 of the rivet tape 100, so as to separate the rivet 101 from the edge strip 102.

[0050] As Figure 7As shown, in the present embodiment, the fine guide and the lower knife assembly are configured as an integral component and are referred to herein collectively as the lower knife assembly 24' having the fine guide portion 18'. The shape of the cross section of the recess 21 of the fine guide portion 18' matches the cross sectional profile of the rivet band 100. On the inner sides of the lower knife assembly 24' opposite to each other, there are respectively provided circular clearance portions, among which one clearance portion 61' is shown in Figure 9 , which is used to accommodate the rivet 101. Figure 8 The bearing 33' is shown in .

[0051] Preferably, the part separating apparatus 1 further comprises an adjustment device 60 for adjusting the spacing between the two longitudinal cutters 27', 27" of the lower knife assembly 24' so as to be suitable for cutting part bands of different widths. It is particularly preferred that an adjustment device (not shown) for adjusting the spacing between the two cutting wheels 25', 25" can also be provided for the upper knife assembly 23 so as to be suitable for cutting part bands of different widths.

[0052] As shown in Figure 4 , the clamping point of the edge strip 102 between the knurling wheels 26', 26" and the lower knife assembly 24 or the bearings 33', 33" is located downstream of the intersection of the cutting wheels 25', 25" and the lower knife assembly cutting edges 32', 32", i.e. the cutting point of the rivet 101 and the connecting portion 103 of the edge strip 102.

[0053] Preferably, pressure plates 29', 29" are provided on the fine guide 18 and the lower knife assembly 24 or on the lower knife assembly 24' having the fine guide portion 18', which together with the fine guide 18 and the lower knife assembly 24 or with the lower knife assembly 24' having the fine guide portion 18' define a clearance having a cross sectional shape matching the cross sectional profile of the rivet band 100, so that the rivet band 100 cannot move up and down and left and right in the clearance when the pressure plates 29', 29" are pressed against the fine guide 18 and the lower knife assembly 24 or against the lower knife assembly 24' having the fine guide portion 18'. Thus, the rivet band 100 is guided more accurately. Preferably, as shown in Figure 7 , the recess 21 of the fine guide 18 or the fine guide portion 18' has a rounded portion at the upstream end adjacent to the coarse guide 17 to facilitate the smooth entry of the rivet band 100 into the clearance. The ends of the pressure plates 29', 29" are provided with a curvature to guide the edge strip 102 downwardly into the edge strip output slot 12. The pressure plates 29', 29" have a notch 35 (as shown in Figure 4 and Figure 10 ) in the cutting area to accommodate the cutting wheels 25', 25".

[0054] As shown in Figure 11As shown, the shaft 30 of the cutting wheels 25', 25" and the knurling wheels 26', 26" is preferably connected via shaft bearings 34', 34" (see [link]). Figure 5 It is supported on the upper brackets 37' and 37" and the upper brackets 37' and 37" are installed on the worktable 9.

[0055] Workbench 9 has a long, narrow longitudinal slit 62 (see...) Figure 5 The rivets 101 separated from the rivet band 100 fall through the longitudinal slit 62 and via the rivet output groove 13 into the rivet bucket 7 below the worktable 9. The rivet output groove 13 is installed below the worktable 9 to communicate with the longitudinal slit 62. The edge strips 102 of the rivet band fall through the longitudinal slit 62 and via the edge strip output groove 12 installed in the longitudinal slit 62 into the edge strip bucket 5 below the worktable 9. Preferably, the width of the portion of the longitudinal slit 62 corresponding to the rivet bucket 7 is narrower, and the width of the portion corresponding to the edge strip bucket 5 is wider. The guiding device 14 is used to correctly guide the rivet band 100 into the cutting device 15 so that the rivet band 100 can be correctly cut in the cutting device 15. Alternatively, the parts separation device 1 may also have other types of rivet collecting devices or edge strip collecting devices, and the rivets or edge strips may be transported to the rivet collecting device or edge strip collecting device, for example, via an output device preferably provided on the worktable for rivets or edge strips.

[0056] like Figure 4 As shown, the parts separation device 1 preferably further includes a cutting device 16 disposed downstream of the cutting device 15 and below the edge strip output groove 12. The cutting device 16 cuts the remaining edge strip 102 of the rivet band 100 after the rivet 101 is separated into edge strip segments for easy collection and processing of edge strip waste. These edge strip segments then fall directly into the edge strip bin 5 below the worktable 9. Figure 12 As shown, the cutting device 16 has a first rotating wheel 39 and a second rotating wheel 40 that can rotate about their own axis, and one or more cutters are mounted on the second rotating wheel 40. Figure 12 Two cutters 55' and 55" are shown. These two cutters 55' and 55" can be fixed to the second roller 40, for example, with screws. The remaining two edge strips 102 of the rivet band 100 are guided via edge strip output slots 12 to between the first roller 39 and the second roller 40 of the cutting device 16, and are shortened by the interaction of the cutters 55' and 55" on the second roller 40 with the first roller 39, facilitating the collection of edge strip waste. The cutting device 16 is supported on lower supports 38' and 38" (see [link]). Figure 14 and Figure 15 The lower brackets 38' and 38" are fixed below the worktable 9.

[0057] exist Figure 13 and Figure 14The image shows perspective views of the part separation device according to the present invention from both above and below. Figure 15 The main parts of the parts separation device 1 according to the present invention are shown, wherein the worktable is not shown.

[0058] like Figure 14 and Figure 15 As shown, the parts separation device 1 also includes a motor 22, a clutch 28, and a transmission system 36. The motor 22 is fixed to the worktable 9 by a motor bracket 48. The clutch 28 is located between the motor 22 and the transmission system 36.

[0059] A first pulley 41 is provided at one end of the shaft 30 of the cutting wheels 25', 25" and the knurling wheels 26', 26" (see...). Figure 5 and Figure 11 ), and a second pulley 44 is provided on the shaft 46 of the second rotating wheel 40 of the cutting device 16 (see Figure 14 and Figure 15 A continuous annular belt 45 is provided on the first pulley 41 and the second pulley 44. The transmission system 36 includes the second pulley 44, the belt 45, the first pulley 41, and the shaft 30. The output shaft of the clutch 28 is coupled to the shaft 46 of the second pulley 40 of the cutting device 16.

[0060] Additionally, the parts separation device 1 may also be equipped with a manual operating device 47 (see...) Figure 5 and Figure 13 to Figure 15 The manual operating device 47 is preferably supported on the operating device bracket 52 via bearings. The operating device bracket 52 is mounted on the worktable 9. The manual operating device 47 has a handle 49, a connecting rod 50, a engagement part 51, and a return spring 53. A mating engagement part 42 is provided at one end of the shaft 30 of the cutting wheels 25', 25" and knurling wheels 26', 26" of the upper blade assembly 23 (see...). Figure 5 and Figure 11 During manual operation, the engaging member 51 of the manual operating device 47 engages with the mating engagement portion 42. By pressing the connecting rod 50 towards the upward blade assembly 23 to compress the return spring 53, the engaging member 51 engages with the mating engagement portion 42 and is locked in this engagement state by a locking device or a suction device (not shown). When the locking device or the suction device is unlocked, the return spring 53 returns to its original position, thereby releasing the engagement state. Figure 5 The reset state of the return spring 53 is shown. The attraction device can be constructed as a magnet.

[0061] A first proximity sensor 56 is installed on the cabinet door 11 of the cabinet 4 of the parts separation equipment 1 (see...). Figure 3), which is used to detect the opening and closing state of the cabinet door 11, to prevent the part separating device from working in the state of exposed cutters. If the first proximity sensor 56 detects that the cabinet door 11 is opened during the operation of the device, the power supply is automatically cut off, so that the power output of the motor 22 is cut off. Similarly, a second proximity sensor 57 (see Fig. 2) is arranged on the engaging part 51 of the manual operating device 47, which is used to detect whether the engaging part 51 contacts the mating engaging part 42. If the second proximity sensor 57 detects that the engaging part 51 of the manual operating device 47 contacts the mating engaging part 42 during the operation of the device, the transmission system 36 and the motor 22 are disconnected by the clutch 28. Otherwise, the manual operation is not possible or very difficult. Figure 5

[0062] The working processes of the automatic mode and the manual mode of the part separating device 1 according to the present application are described below respectively.

[0063] In the automatic mode, first of all, it is ensured that the cabinet door 11 of the part separating device 1 is closed and the engaging part 51 of the manual operating device 47 is not engaged to the mating engaging part 42, and then the start button 6' is pressed. The motor 22 operates, the power is transmitted to the rotating shaft 46 of the second rotating wheel 40 of the cutting-off device 16 via the clutch 28 and then transmitted to the rotating shaft 30 of the cutting wheels 25', 25" and knurl wheels 26', 26" of the upper cutter set 23 via the transmission system 36 (the second pulley 44, the endless belt 45 and the first pulley 41). The rotation of the rotating shaft 30 drives the rotation of the cutting wheels 25', 25" and knurl wheels 26', 26" of the upper cutter set 23.
