Description

Technical Field

[0001] This application relates to the field of collating technology, and in particular to a transmission device and a collating machine. Background Technology

[0002] A collating machine is a machine used to produce books and periodicals, collating folded bookplates or individual pages of a desired format according to page number order to form a book block. A collating machine consists of multiple individual collating machines, all with interconnected drive shafts. Each individual collating machine has an independent drive shaft, and each drive shaft is connected to the drive shaft and can rotate under its drive. In existing collating machines, the speed of the drive shaft is typically changed by altering the speed of the drive shaft.

[0003] However, although the speed of each drive shaft changes after the rotation speed is adjusted, the rotation speed of multiple drive shafts is the same. This means that each collating machine in a single collating machine has the same operating speed, and a single collating machine cannot meet the collating needs of different sizes of book marks or pages at the same time. Summary of the Invention

[0004] Therefore, it is necessary to provide a transmission device and a collating machine that allows for easy individual adjustment of the rotation speed of the transmission shaft.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A transmission device is applied in a collating machine. The transmission device includes multiple drive shafts, multiple transmission shafts, and a transmission module. Each drive shaft, transmission shaft, and transmission module is arranged in a one-to-one correspondence. Each drive shaft is connected to its corresponding transmission shaft through the transmission module. The multiple drive shafts are linked together. The transmission module includes a transmission gear, a transmission mechanism, and multiple drive gears. The transmission gear is rotatably mounted on each drive shaft and connected to its corresponding transmission shaft through the transmission mechanism to control the rotation speed of the corresponding transmission shaft under the drive of the transmission gear.

[0007] Multiple drive gears are circumferentially mounted on each drive shaft, wherein each drive gear can be driven to connect with the transmission gear, and the transmission ratio of each drive gear when driven to connect with the transmission gear is different.

[0008] Understandably, when multiple drive shafts rotate in tandem, multiple drive gears on each drive shaft rotate under the drive of the drive shaft, and each drive gear can be connected to the transmission gear with a different transmission ratio, so that each drive gear can drive the transmission gear to rotate at a different speed. In this way, the operator can choose to connect the transmission gear on each drive shaft to different drive gears, so that the rotation speed of the transmission gear on each drive shaft is different. Thus, when the transmission mechanism controls the rotation of the transmission shaft under the drive of the transmission gear, the rotation speed of each transmission shaft is different. When this transmission device is applied to a collating machine, the rotation speed of the transmission shaft in each collating machine can be adjusted independently, so that a collating machine can work at different speeds to meet the collating needs of different sizes of pages or books at the same time.

[0009] In one embodiment, the transmission module further includes a plurality of connecting gears, which are disposed around the plurality of driving gears and the transmission gears, and the plurality of connecting gears are configured in a one-to-one correspondence with the plurality of driving gears;

[0010] Each of the drive gears can be connected to the transmission gear via the corresponding connecting gear.

[0011] It is understandable that multiple connecting gears are placed around multiple driving gears and transmission gears to facilitate the connection and assembly of the connecting gears with the transmission gears and corresponding driving gears when they mesh, so as to realize the transmission connection between the driving gears and transmission gears and enable the driving gears to drive the transmission gears to rotate.

[0012] In one embodiment, the number of the drive gear and the connecting gear is set to two, with the two connecting gears arranged at intervals on both sides of the transmission gear along the circumferential direction of the drive shaft.

[0013] It is understandable that by setting two drive gears and two connecting gears in correspondence, the transmission gears will have two different transmission speeds. This also helps to simplify the assembly between the connecting gears, drive gears, and transmission gears, and avoids the complexity of assembly caused by an excessive number of drive gears and connecting gears.

[0014] In one embodiment, the transmission module further includes a gear seat and a handle, with the two connecting gears rotatably mounted on the gear seat;

[0015] The handle is fixedly connected to the gear seat, and the gear seat can move relative to the transmission gear under the drive of the handle, so that one of the two connecting gears can be selectively connected to the corresponding drive gear.

[0016] Understandably, by fixing the handle to the gear seat, the operator can change the position of the connected gear by moving the handle, thereby changing the transmission ratio between the drive shaft and the transmission shaft. This simple operation makes it easy for the operator to use.

[0017] In one embodiment, the transmission module further includes a positioning mechanism that can act on the gear seat to position the two extreme positions of the gear seat relative to the drive shaft.

[0018] At one of the extreme positions, one of the connecting gears is simultaneously connected to the transmission gear and the corresponding drive gear; at the other extreme position, the other connecting gear is simultaneously connected to the transmission gear and the corresponding drive gear.

[0019] It is understandable that by setting a positioning mechanism to position the two extreme points when the gear seat moves, the position of the connecting gear is fixed, thereby improving the transmission stability when the connecting gear meshes with the transmission gear and the corresponding drive gear.

[0020] In one embodiment, the positioning mechanism includes a positioning component and a fixing plate, and the gear seat is pivotally mounted on the fixing plate;

[0021] The positioning component is mounted on the gear seat and can abut against the fixing plate to position the gear seat onto the fixing plate.

[0022] It is understandable that the positioning component is mounted on the gear seat so that the positioning component can cooperate with the fixed plate to achieve positioning.

[0023] In one embodiment, the positioning component further includes a positioning head, a positioning sleeve, and an elastic element. The positioning head is retractably mounted on the positioning sleeve, and the elastic element is pre-compressed and installed inside the positioning sleeve. The elastic element abuts against the positioning sleeve to elastically support the positioning head.

[0024] A positioning block is installed on the fixed plate. The positioning block has a positioning groove. The positioning groove is matched with the positioning head. The positioning block can be inserted into the positioning groove under the push of the elastic member to limit the positioning head to the positioning block and position the positioning head on the fixed plate.

[0025] Understandably, the positioning head is inserted into the positioning groove under the action of the elastic element to achieve the positioning of the positioning component. The positioning head is also retractable, so that when the positioning head moves out of the positioning groove, it can squeeze the elastic element and retract into the positioning sleeve, which facilitates the movement of the positioning head.

[0026] In one embodiment, the cross-section of the positioning groove is set as a triangle;

[0027] Furthermore, the end face of the positioning head that extends out of the positioning sleeve is set as an arc surface.

[0028] Understandably, setting the cross-section of the positioning groove to be triangular and one end face of the positioning head to be an arc surface reduces the resistance encountered when the positioning head disengages from the positioning groove during the switching process, resulting in smooth movement of the positioning head and facilitating positioning switching.

[0029] In one embodiment, the positioning component further includes an elastic abutment block disposed within the positioning sleeve and abutting against an end of the elastic element away from the positioning head;

[0030] The elastic abutment block can be adjusted in position relative to the positioning sleeve.

[0031] Understandably, the degree of compression of the elastic element within the positioning sleeve can be adjusted by the elastic element abutment to control the tightness of the elastic element.

[0032] This application also provides the following technical solutions:

[0033] A collating machine includes the transmission device described in any one of the above claims.

[0034] It is understandable that in a collating machine using the aforementioned transmission device, the drive shaft and transmission shaft can transmit power at different transmission ratios, and multiple collating machines in a collating machine can work at different speeds, enabling a single collating machine to simultaneously meet the collating needs of different sizes of pages or books.

[0035] Due to the application of the above solution, this application has the following advantages compared with the prior art:

[0036] The transmission device and collating machine claimed in this application, when multiple drive shafts rotate in tandem, all drive gears on each drive shaft rotate under the drive of the drive shaft, and each drive gear can be connected to the transmission gear with a different transmission ratio, so that each drive gear can drive the transmission gear to rotate at a different speed. In this way, the operator can choose to connect the transmission gear on each drive shaft to different drive gears, so that the rotation speed of the transmission gear on each drive shaft is different. Thus, when the transmission mechanism controls the rotation of the transmission shaft under the drive of the transmission gear, the rotation speed of each transmission shaft is different. When this transmission device is applied to a collating machine, the rotation speed of the transmission shaft in each collating machine can be adjusted independently, so that a collating machine can work at different speeds to meet the collating needs of different sizes of book pages or books at the same time.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0050] Please see Figure 1 and Figure 2 An embodiment of this application provides a transmission device 100, which includes multiple drive shafts 10, multiple transmission shafts 20, and a transmission module. The drive shafts 10, transmission shafts 20, and transmission modules are all configured in a one-to-one correspondence. Each drive shaft 10 is connected to the corresponding transmission shaft 20 through the transmission module. The multiple drive shafts 10 can be linked together under the drive of a motor (not shown).

[0051] The transmission module includes drive gears 11, transmission gears 12, and a transmission mechanism. Multiple drive gears 11 are circumferentially mounted on each drive shaft 10, and these multiple drive gears 11 can rotate together under the drive of the drive shaft 10. A transmission gear 12 is also rotatably mounted on each drive shaft 10 via bearings. The transmission gear 12 is connected to the transmission shaft 20 via the transmission mechanism 50, allowing the transmission mechanism 50 to control the rotational speed of the corresponding transmission shaft 20 under the drive of the transmission gear 12.

[0052] Each drive gear 11 can be connected to the transmission gear 12, and the transmission ratio of each drive gear 11 and transmission gear 12 is different. It is understood that when multiple drive shafts 10 rotate in tandem, multiple drive gears 11 on each drive shaft 10 rotate together under the drive of the drive shaft 10, and each drive gear 11 can be connected to the transmission gear 12 with different transmission ratios, so that each drive gear 11 can drive the transmission gear 12 to rotate at different speeds. In this way, the operator can choose to connect the transmission gear 12 on each drive shaft 10 to different drive gears 11, so that the rotation speed of the transmission gear 12 on each drive shaft 10 is different. As a result, when the transmission mechanism 50 controls the corresponding transmission shaft 20 to rotate under the drive of the transmission gear 12, the rotation speed of each transmission shaft 20 is different. When this transmission device 100 is applied to a collating machine, the rotation speed of the transmission shaft 20 in each collating machine can be adjusted independently, so that a collating machine can work at different speeds to meet the collating needs of different sizes of book pages or books at the same time.

[0053] In this embodiment, the multiple drive shafts 10 are configured as an integral structure. Of course, in other embodiments, the multiple drive shafts 10 can also be configured as separate structures and connected and fixed to each other to form a whole, which is not limited here.

[0054] In one embodiment, the transmission module further includes a plurality of connecting gears 31, which are spaced apart around the drive gear 11 and the transmission gear 12 along the circumferential direction of the drive shaft 10, and are movable relative to the drive gear 11 and the transmission gear 12, so that the plurality of connecting gears 31 can adjust their positions and selectively mesh with the transmission gear 12 and one of the corresponding drive gears 11.

[0055] Moreover, multiple connecting gears 31 are arranged one-to-one with multiple driving gears 11. That is to say, the number of connecting gears 31 is the same as the number of driving gears 11, so that each driving gear 11 can be connected to the transmission gear 12 through the corresponding connecting gear 31 to realize the transmission between the driving gear 11 and the transmission gear 12.

[0056] like Figure 3As shown, in one embodiment, the number of both the drive gear 11 and the connecting gear 31 is set to two. The two connecting gears 31 are arranged at intervals on both sides of the transmission gear 12 along the circumferential direction of the drive shaft 10. This simplifies the assembly of the drive gear 11 and the connecting gear 31 and avoids the complexity of the assembly arrangement caused by an excessive number of drive gears 11 and connecting gears 31. Of course, in other embodiments, the number of drive gears 11 and connecting gears 31 can also be set to three or four, etc., which will not be elaborated here.

[0057] It is understandable that since each drive gear 11 has a different transmission ratio when connected to the transmission gear 12 via the corresponding connecting gear 31, by correspondingly setting two drive gears 11 with two connecting gears 31, when one of the two drive gears 11 is connected to the corresponding connecting gear 31 and transmission gear 12, the transmission gear 12 can switch between two different rotational speeds. Thus, the operator can select one of the two connecting gears 31 to mesh with the corresponding drive gear 11, ensuring that the transmission ratio between the drive shaft 10 and the transmission shaft 20 meets the usage requirements.

[0058] Specifically, the transmission gear 12 has 44 teeth. The two drive gears 11 are a first drive gear 111 and a second drive gear 112, with the first drive gear 111 having 44 teeth and the second drive gear 112 having 33 teeth. The two connecting gears 31 are a first connecting gear 311 and a second connecting gear 312, with the first drive gear 111 corresponding to the first connecting gear 311 and the second drive gear 112 corresponding to the second connecting gear 312, with the first connecting gear 311 having 22 teeth. The second connecting gear 312 has a double-row gear structure, with 33 teeth meshing with the second drive gear 112 and 22 teeth meshing with the transmission gear 12.

[0059] Not limited to this, the number of teeth of the aforementioned transmission gear 12, drive gear 11 and connecting gear 31 can also be set to other values, as long as each drive gear 11 can drive the transmission gear 12 to rotate at different speeds when it is connected to the transmission gear 12 through the corresponding connecting gear 31.

[0060] In this embodiment, the first drive gear 111 and the second drive gear 112 are set as an integral structure, that is, the two drive gears 11 form a double-row gear structure, which helps to simplify the structure of the drive gear 11.

[0061] like Figure 1 , Figure 3 and Figure 6As shown, in one embodiment, the transmission module further includes a gear seat 30 and a handle 32. Two connecting gears 31 are rotatably mounted on the gear seat 30, allowing the connecting gears 31 to change position as the gear seat 30 swings. The gear seat 30 is rotatably mounted on a fixed plate 42 via a connector 33, allowing the gear seat 30 to swing around the connector 33. The handle 32 is fixedly connected to the gear seat 30 via bolts or screws, and the handle 32 can control the movement of the gear seat 30 relative to the drive shaft 10, causing the two connecting gears 31 on the gear seat 30 to displace relative to the drive gear 11 and transmission gear 12. This allows one of the two connecting gears 31 on each side of the drive shaft 10 to selectively engage with the corresponding drive gear 11 and transmission gear 12. Thus, the operator can change the position of the connecting gears 31 by moving the handle 32, thereby changing the transmission ratio between the drive shaft 10 and the transmission shaft 20. The operation is simple and convenient for the operator.

[0062] Furthermore, since other components are arranged around the handle 32, in order to avoid interference between the handle 32 and other components, the shape of the handle 32 is set as a bent structure to avoid other components.

[0063] like Figure 1 As shown, in one embodiment, the transmission module further includes a positioning mechanism 40. The positioning mechanism 40 can act on the gear seat 30 to limit the swing amplitude of the gear seat 30 and position the two extreme positions of the gear seat 30 relative to the drive shaft 10. At this time, the number of drive gear 11 and connecting gear 31 is set to two. After positioning, the two connecting gears 31 are located in fixed positions, which prevents the gear seat 30 from shaking during transmission and helps to improve the stability when the connecting gear 31 meshes with the transmission gear 12 and the corresponding drive gear 11.

[0064] In one of the extreme positions, one connecting gear 31 is simultaneously connected to both the transmission gear 12 and the corresponding drive gear 11; in the other extreme position, the other connecting gear 31 is simultaneously connected to both the transmission gear 12 and the corresponding drive gear 11. That is, when the gear seat 30 is in the extreme position, when one connecting gear 31 is in a position that can mesh with the corresponding drive gear 11 and the transmission gear 12, the other connecting gear 31 is disengaged from the corresponding drive gear 11 and the transmission gear 12.

[0065] like Figure 1In this embodiment, the first pole position is shown as the handle 32 drawn with a solid line in the figure, and the second pole position is shown as the handle 32 drawn with a dashed line in the figure. When the handle 32 is located at the first pole position, the transmission ratio between the drive shaft 10 and the transmission shaft 20 is 1:1; when the handle 32 is located at the second pole position, the transmission ratio between the drive shaft 10 and the transmission shaft 20 is 1:2.

[0066] like Figure 2 and Figure 5 As shown, in one embodiment, the positioning mechanism 40 includes a positioning component 41 and a fixing plate 42. The gear seat 30 is rotatably mounted on the fixing plate 42 via a connector 33. The positioning component 41 is mounted on the gear seat 30 and can abut against the fixing plate 42 so that the gear seat 30 can be positioned on the fixing plate 42 by the positioning component 41.

[0067] In other embodiments, the positioning mechanism 40 may also be configured as a pin, a latch, etc., which will not be elaborated here.

[0068] like Figure 5 As shown, in one embodiment, the positioning assembly 41 further includes a positioning head 411, a positioning sleeve 412, and an elastic member 413. The positioning sleeve 412 has a hollow structure. The positioning head 411 is retractably mounted on the positioning sleeve 412. The elastic member 413 is pre-compressed and installed inside the positioning sleeve 412. The elastic member 413 abuts against the portion of the positioning sleeve 412 located inside the positioning sleeve 412 to elastically support the positioning head 411. A positioning block 421 is fixedly mounted on the fixing plate 42. A positioning groove 422 is formed on the positioning block 421. The positioning groove 422 is matched with the positioning head 411, and the positioning block 421 can be inserted into the positioning groove 422 under the pushing of the elastic member 413 to limit the positioning head 411 to the positioning block 421 and position the positioning head 411 on the fixing plate 42. Thus, the positioning head 411 can be inserted into the positioning groove 422 under the action of the elastic member 413 and abut against the groove wall of the positioning groove 422 to achieve the positioning of the positioning component 41 and the fixing plate 42. When the handle 32 moves, the handle 32 can drive the gear seat 30 and the positioning component 41 installed on the gear seat 30 to move together. After the positioning head 411 moves out of the positioning groove 422, it can squeeze the elastic member 413 and retract into the positioning sleeve 412, which facilitates the movement of the positioning head 411.

[0069] Preferably, the elastic element 413 is a return spring. Of course, in other embodiments, the elastic element 413 may also be a return sheet or elastic rubber, etc., which will not be listed here.

[0070] Preferably, the cross-section of the positioning groove 422 is triangular, and the end face of the positioning head 411 extending out of the positioning sleeve 412 is an arc surface. In this way, when the positioning head 411 disengages from the positioning groove 422, the resistance it experiences is small, the movement of the positioning head 411 is smooth, and positioning switching is convenient.

[0071] like Figure 5 As shown, in one embodiment, the positioning component 41 further includes an elastic abutment 4121, which is disposed within the positioning sleeve 412 and abuts against the end of the elastic member 413 away from the positioning head 411. The elastic abutment 4121 is capable of adjusting its position relative to the positioning sleeve 412. Thus, the degree of compression of the elastic member 413 within the positioning sleeve 412 can be adjusted by the elastic abutment 4121 to control the tightness of the elastic member 413.

[0072] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the transmission mechanism 50 includes a bridge gear 51, an upper gear 52, and a first sprocket 53. A second sprocket 21 is mounted on each transmission shaft 20. The bridge gear 51 and the upper gear 52 are both mounted on a fixed plate 42. The upper gear 52 is relatively fixed to the first sprocket 53 and can rotate coaxially. The first sprocket 53 and the second sprocket 21 are connected by a chain 54. The bridge gear 51 is positioned between the transmission gear 12 and the upper gear 52 and meshes stably with them. The number of transmission mechanisms 50 is the same as the number of transmission shafts 20, and each transmission gear 12 can drive the transmission shaft 20 to rotate through one transmission mechanism 50.

[0073] Specifically, the bridge gear 51 has 22 teeth, the upper gear 52 has 44 teeth, the first sprocket 53 has 20 teeth, and the second sprocket 21 has 40 teeth.

[0074] This application also provides a collating machine (not shown), including the transmission device 100 described in any of the above claims. The collating machine is formed by combining multiple individual collating machines. Each individual collating machine has a drive shaft 10 and a transmission shaft 20, and the drive shaft 10 and the transmission shaft 20 are connected via a transmission module. It is understood that in a collating machine using the aforementioned transmission device 100, the drive shaft 10 and the transmission shaft 20 can transmit power at different transmission ratios, and the transmission shaft 20 in each individual collating machine can be individually controlled to rotate at different speeds. Multiple individual collating machines can operate simultaneously at different speeds. Since different speeds are suitable for different sizes of book pages or bookmarks, a single collating machine can simultaneously meet the collating needs of different sizes of book pages or bookmarks.

[0075] In one embodiment, the collating machine is provided with a control interface (not shown). The control interface has a variety of different options to match different transmission ratios between the drive shaft 10 and the transmission shaft 20, thereby meeting the detection requirements at different speeds.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
