[0003] At present, pneumatic equipment is often used to drive the material tray containing multiple medicine bottles to move, or a robot is used to clamp and drive the aforementioned material tray to move. However, pneumatic equipment and robots each have major defects. For example, the leakage of compressed air from pneumatic equipment will pollute the sterile environment of the filling area, and the installation of pneumatic equipment in the product will greatly increase the difficulty of isolating the product as a whole; the robot has a complex structure and is difficult to be arranged flexibly and at low cost according to the specific liquid medicine filling operation. Therefore, it is not highly adaptable to specific pharmaceutical production lines. Summary of the invention

[0006] Preferably, the working platform is also provided with a guide rail; the guide rail, the transverse synchronous belt and the longitudinal synchronous belt are all arranged on the same surface of the working platform; the guide rail is parallel to the transport direction of the transverse synchronous belt; the longitudinal bracket and any one of the transverse brackets are located above the guide rail and slidably fit the guide rail.

[0007] Preferably, the upper surface of the working platform is also provided with a roller groove which is recessed downward and parallel to the guide rail; one end of the longitudinal movement bracket is provided with a longitudinal movement slider which slides with the guide rail, and the other end is provided with a roller I which is embedded in the roller groove; one end of any of the transverse movement brackets is provided with a transverse movement slider which slides with the guide rail, and the other end is provided with a roller II which is embedded in the roller groove.

[0008] Preferably, the transverse synchronous belt and the longitudinal synchronous belt both include a pulley, a belt body and a servo motor.

[0009] Preferably, a strip-shaped pallet fixing plate is provided at the bottom of the movable frame; the first sliding portion is located in the middle of the pallet fixing plate along the length direction, and the two second sliding portions are respectively located at both ends of the pallet fixing plate along the length direction.

[0010] Preferably, the first sliding portion comprises a rotating shaft vertically fixed to the tray fixing plate and a ball bearing sleeved on the bottom end of the rotating shaft; the ball bearing is embedded in and slidably fitted in the horizontal guide groove.

[0011] Preferably, two parallel and adjacent rotating shafts are provided in the tray fixing plate; the ball bearings of the two rotating shafts are both embedded in the horizontal guide groove, any one of the ball bearings only rolls in contact with one groove side wall of the horizontal guide groove, and the two ball bearings respectively roll in contact with the two groove side walls of the horizontal guide groove.

[0012] Preferably, a mounting groove for holding a material pallet is provided on the top of the movable frame; the mounting groove is suspended above the pallet fixing plate.

[0013] Preferably, the mounting groove is specifically a horizontal slot for realizing the pull-out movement of the material tray in the horizontal direction.

[0014] Compared with the above-mentioned background technology, the material pallet moving device provided by the present invention includes a working platform, a transverse synchronous belt, a longitudinal synchronous belt and a moving frame; the transverse synchronous belt and the longitudinal synchronous belt are parallel and spaced, and the pulley shafts of the two are vertically fixed to the working platform, and the belt body of the transverse synchronous belt is fixedly connected with at least two transverse brackets; the belt body of the longitudinal synchronous belt is fixedly connected with a longitudinal bracket; the upper surface of the longitudinal bracket is provided with a horizontal guide groove, and the groove length direction of the horizontal guide groove intersects with the transportation direction of the longitudinal synchronous belt at 45°; the bottom of the moving frame is provided with a first sliding part that slidably cooperates with the horizontal guide groove and a second sliding part that slidably cooperates with all the transverse brackets respectively; the sliding direction of any second sliding part is horizontal and perpendicular to the transportation direction of the transverse synchronous belt.

[0015] The material tray moving device utilizes a longitudinal synchronous belt and a transverse synchronous belt to drive the moving frame to move relative to the working platform.

[0016] When the longitudinal synchronous belt is turned on and the transverse synchronous belt is turned off, the horizontal guide groove of the longitudinal bracket moves relative to the first sliding part of the mobile frame, and the transverse displacement component of this movement is borne by the longitudinal bracket, that is, the longitudinal bracket moves with the belt body of the longitudinal synchronous belt, and the mobile frame is constrained by the transverse synchronous belt through the first sliding part and cannot move with the belt body of the longitudinal synchronous belt; the longitudinal displacement component of this movement is borne by the second sliding part of the mobile frame, that is, the second sliding part slides relative to the transverse bracket, and this sliding direction is perpendicular to the transportation direction of the transverse synchronous belt, which is also perpendicular to the transportation direction of the longitudinal synchronous belt. It can be seen that when the longitudinal synchronous belt is turned on and the transverse synchronous belt is turned off, the material tray moving device drives the mobile frame and the material tray mounted on the mobile frame to produce longitudinal displacement.

[0017] When the longitudinal synchronous belt and the transverse synchronous belt are both turned on and move in the same direction and at the same speed, the first sliding part and the horizontal guide groove are relatively stationary, and the second sliding part and the transverse bracket are relatively stationary. Therefore, the movement state of the transverse bracket and the longitudinal bracket is also the movement state of the mobile frame. In other words, the mobile frame produces lateral displacement with the transverse bracket and the longitudinal bracket.

[0018] It can be seen that the material tray moving device can use two synchronous belt mechanisms installed in parallel on the working platform as longitudinal synchronous belts and transverse synchronous belts respectively, to realize the lateral drive and longitudinal drive of the material tray. The longitudinal synchronous belt and the transverse synchronous belt can meet the movement of the material tray in a larger range, and will not affect the sterile environment of the occasion due to problems such as air leakage and oil leakage during the movement. In addition, the longitudinal synchronous belt and the transverse synchronous belt jointly support and drive the mobile frame and the material tray. In other words, the longitudinal synchronous belt and the transverse synchronous belt do not have to support each other, so the driving method is simpler and easier, the movement is smoother and more precise, and the driving effect of any synchronous belt mechanism on the mobile frame and the material tray can be better exerted.

[0019] When the material tray moving device is applied to the filling operation of medicine bottle containers in a pharmaceutical factory, the moving frame can drive the material tray and the medicine bottle containers placed on the material tray to achieve lateral and longitudinal movement relative to the filling needle, so that the filling needle can be inserted into multiple medicine bottle containers in turn to meet the filling requirements of several medicine bottle containers.

[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Please refer to Figures 1 to 9 , Figure 1 A schematic diagram of the structure of a material tray moving device provided in an embodiment of the present invention; Figure 2 for Figure 1 A partial enlarged view of the mobile frame, the transverse support and the longitudinal support; Figure 3 for Figure 1 A top view of Figure 4 A schematic diagram of the partial structure of the material pallet moving device provided in an embodiment of the present invention at the pallet fixing plate, the transverse moving bracket and the longitudinal moving bracket; Figure 5 for Figure 1 Left view of Figure 6 A schematic diagram of the assembly of the transverse moving bracket, the longitudinal moving bracket and the ball bearing in a first direction provided by an embodiment of the present invention; Figure 7 A schematic diagram of the assembly of the transverse moving bracket, the longitudinal moving bracket and the ball bearing in the second direction provided by an embodiment of the present invention; Figure 8 A schematic diagram of the assembly of the transverse moving bracket, the longitudinal moving bracket and the pallet fixing plate provided in an embodiment of the present invention; Fig. 9 A partial enlarged view of the roller slideway, guide rail, transverse support, longitudinal support and moving part of the material pallet moving device provided in an embodiment of the present invention.

[0034] The present invention provides a material pallet moving device, comprising a working platform 1, a transverse synchronous belt 21 arranged on the working platform 1, a longitudinal synchronous belt 22 arranged on the working platform 1, and a moving frame 3 installed on the aforementioned transverse synchronous belt 21 and the aforementioned longitudinal synchronous belt 22; the moving frame 3 is used to clamp the material pallet 01 so that the material pallet 01 can be driven to move relative to the working platform 1 through the moving frame 3; the transverse synchronous belt 21 and the longitudinal synchronous belt 22 are parallel and spaced apart on the working platform 1 and extend in the same direction, and the pulley shaft 200 of the transverse synchronous belt 21 is vertically fixed to the working platform 1. Obviously, the pulley shaft 200 of the longitudinal synchronous belt 22 is also vertically fixed to the working platform 1.

[0035] Both the transverse synchronous belt 21 and the longitudinal synchronous belt 22 have a pulley 202 and a belt body 201, and the pulley shaft 200 is a driving shaft of the pulley 202. Generally speaking, the transverse synchronous belt 21 and the longitudinal synchronous belt 22 can adopt a synchronous belt mechanism with exactly the same structure.

[0036] In this embodiment, the belt body 201 of the transverse synchronous belt 21 is fixedly connected with at least two transverse brackets 4, and the belt body 201 of the longitudinal synchronous belt 22 is fixedly connected with a longitudinal bracket 5. The upper surface of the longitudinal bracket 5 is provided with a horizontal guide groove, which is horizontally distributed and the groove length direction intersects with the transportation direction of the longitudinal synchronous belt 22 at 45 degrees. The bottom of the mobile frame 3 is provided with a first sliding part and a second sliding part. The first sliding part is slidably matched with the horizontal guide groove of the longitudinal bracket 5. The sliding direction of the first sliding part is the extension direction of the groove body of the horizontal guide groove. The second sliding part is slidably matched with all the transverse brackets 4. The sliding direction of the second sliding part is horizontal and perpendicular to the transportation direction of the transverse synchronous belt 21. Among them, since the sliding direction of the first sliding part is the extension direction of the groove body of the horizontal guide groove, and the horizontal guide groove intersects with the transportation direction of the longitudinal synchronous belt 22 at 45 degrees, the sliding direction of the first sliding part intersects with the transportation direction of the longitudinal synchronous belt 22 at 45 degrees. It can be seen that the movable frame 3 is installed above the transverse synchronous belt 21 and the longitudinal synchronous belt 22 by utilizing the sliding cooperation relationship between the first sliding part and the second sliding part and the transverse bracket 4 and the longitudinal bracket 5 respectively. Therefore, when the transverse synchronous belt 21 and the longitudinal synchronous belt 22 are turned on, the movable frame 3 can be driven to realize transverse horizontal movement and longitudinal horizontal movement.

[0037] When the transverse synchronous belt 21 and the longitudinal synchronous belt 22 are used to drive the moving frame 3 to move, there are two operation modes: only turning on the longitudinal synchronous belt 22 and turning on the longitudinal synchronous belt 22 and the transverse synchronous belt 21 at the same time.

[0038] For the convenience of expression, the X-axis is used to represent the transport direction of the longitudinal synchronous belt 22. Since the transverse synchronous belt 21 is parallel to the longitudinal synchronous belt 22, the X-axis is also used to represent the transport direction of the transverse synchronous belt 21, and the Y-axis can be used to represent the sliding direction of the second sliding part.

[0039] When only the longitudinal synchronous belt 22 is turned on, the belt body 201 of the longitudinal synchronous belt 22 moves along the X-axis while the belt body 201 of the transverse synchronous belt 21 is stationary. The belt body 201 of the longitudinal synchronous belt 22 drives the longitudinal bracket 5 and its horizontal guide groove to move along the X-axis. Under the motion constraint of the horizontal guide groove, the relative motion of the first sliding part and the horizontal guide groove can be decomposed into the X-axis and the Y-axis. Since the transverse synchronous belt 21 and its transverse bracket 4 are stationary, the displacement component of the first sliding part and the horizontal guide groove along the X-axis only moves the longitudinal bracket 5 along the X-axis, and the displacement component of the first sliding part and the horizontal guide groove along the Y-axis only moves the first sliding part along the Y-axis, thereby realizing the movement of the moving frame 3 along the Y-axis.

[0040] When the longitudinal synchronous belt 22 and the transverse synchronous belt 21 are turned on at the same time, the belt body 201 of the longitudinal synchronous belt 22 and the belt body 201 of the transverse synchronous belt 21 are made to move at the same speed along the X-axis, so that the first sliding part and the horizontal guide groove can be relatively still and the second sliding part and the transverse bracket 4 can be relatively still. At this time, the movement state of the transverse bracket 4 and the longitudinal bracket 5 is also the movement state of the moving frame 3. In other words, the moving frame 3 only moves along the X-axis with the transverse bracket 4 and the longitudinal bracket 5.

[0041] In summary, the material tray moving device provided by the present invention can drive the moving frame 3 to move along the Y axis by only starting the longitudinal synchronous belt 22, and can drive the moving frame 3 to move along the X axis by starting the longitudinal synchronous belt 22 and the transverse synchronous belt 21 at the same time and at the same speed, thereby realizing that the moving frame 3 drives the material tray to move along the X axis and the Y axis. The material tray moving device can use two synchronous belt mechanisms installed in parallel on the working platform 1 as the longitudinal synchronous belt 22 and the transverse synchronous belt 21, respectively, to realize the transverse drive and longitudinal drive of the material tray 01. The two synchronous belt mechanisms can not only meet the transverse and longitudinal movement of the material tray 01 in a larger range, but also will not affect the sterile environment of the occasion where the product is located due to problems such as air leakage and oil leakage during the movement. In addition, the two synchronous belt mechanisms are jointly driven and only used to drive the moving frame 3 and the material tray 01, and do not need to support and drive each other. Therefore, the driving method is simpler and easier, the movement is more stable and reliable, and the driving effect of any synchronous belt mechanism on the moving frame 3 and the material tray 01 can be better exerted.

[0042] This material tray moving device can be applied to the filling operation of medicine bottle containers in pharmaceutical factories, and the moving frame 3 drives the material tray 01 and the medicine bottle containers placed on the material tray 01 to achieve lateral and longitudinal movement relative to the filling needle, so that one or several filling needles are inserted into multiple medicine bottle containers in turn to meet the filling requirements of several medicine bottle containers.

[0043] The material tray moving device provided by the present invention is further described below in conjunction with the accompanying drawings and implementation examples.

[0044] In the material tray moving device, the moving frame 3 is located above the longitudinal synchronous belt 22 and the transverse synchronous belt 21, so the longitudinal synchronous belt 22 and the transverse synchronous belt 21 provide an upward supporting force to the moving frame 3. Due to the structural constraints of the longitudinal synchronous belt 22 and the transverse synchronous belt 21, if the moving frame 3 is supported only by the longitudinal synchronous belt 22 and the transverse synchronous belt 21, not only is the supporting force extremely limited, but also the movement stability of the moving frame 3 cannot be guaranteed. For this reason, the material tray moving device also includes a guide rail 6 arranged on the working platform 1, and the guide rail 6, the transverse synchronous belt 21 and the longitudinal synchronous belt 22 are all arranged on the same surface of the working platform 1. For example, the transverse synchronous belt 21 and the longitudinal synchronous belt 22 are usually arranged on the upper surface of the working platform 1; the guide rail 6 is parallel to the transport direction of the transverse synchronous belt 21, and is also parallel to the transport direction of the longitudinal synchronous belt 22.

[0045] In the above embodiment, any one of the transverse moving brackets 4 of the transverse moving synchronous belt 21 and the longitudinal moving bracket 5 of the longitudinal moving synchronous belt 22 are located above the aforementioned guide rail 6 and are slidably matched with the aforementioned guide rail 6. Therefore, the guide rail 6 can support the movable frame 3 by supporting the transverse moving bracket 4 and the longitudinal moving bracket 5, thereby ensuring the movement stability of the movable frame 3.

[0046] Furthermore, the material pallet moving device also includes a roller groove 7 arranged on the working platform 1 and parallel to the guide rail 6, and the roller groove 7 is recessed downward from the upper surface of the working platform 1; adapted to the roller groove 7, the transverse moving bracket 4 of the transverse moving synchronous belt 21 and the longitudinal moving bracket 5 of the longitudinal moving synchronous belt 22 are both provided with rollers. For example, the transverse moving bracket 4 of the transverse moving synchronous belt 21 is provided with a roller II42, and the longitudinal moving bracket 5 of the longitudinal moving synchronous belt 22 is provided with a roller I53. The aforementioned roller I53 and roller II42 are both embedded in the roller groove 7 to realize rolling along the extension direction of the groove body of the roller groove 7. It can be seen that, for the transverse moving bracket 4 of the transverse moving synchronous belt 21, one end of the transverse moving bracket 4 can be slidably matched with the guide rail 6 through the transverse moving slider 41, and the other end can be rollingly matched with the roller groove 7 through the roller II42; for the longitudinal moving bracket 5 of the longitudinal moving synchronous belt 22, one end of the longitudinal moving bracket 5 can be slidably matched with the guide rail 6 through the longitudinal moving slider, and the other end can be rollingly matched with the roller groove 7 through the roller I53.

[0047] The middle part of the lateral moving bracket 4 can be fixedly connected to the belt body 201 of the lateral moving synchronous belt 21 through the lateral moving synchronous belt fixing plate 44. The middle part of the longitudinal moving bracket 55 can be fixedly connected to the belt body 201 of the longitudinal moving synchronous belt 22 through the longitudinal moving synchronous belt fixing plate 55.

[0048] In order to better support the mobile rack 3, the roller slide 7 and the guide rail 6 of the material tray moving device are located on both sides of the transverse synchronous belt 21 and the longitudinal synchronous belt 22, such as Figure 3 As shown, the roller slideway 7, the transverse synchronous belt 21, the longitudinal synchronous belt 22 and the guide rail 6 are arranged along the Figure 3 The upper and lower directions are arranged sequentially in parallel.

[0049] The above-mentioned lateral synchronous belt 21 and longitudinal synchronous belt 22 both include a pulley 202, a belt body 201 and a servo motor. Using a servo motor to drive the belt body 201 can improve the movement accuracy of the belt body 201, thereby improving the movement accuracy of the moving frame 3, including the lateral movement accuracy and the longitudinal movement accuracy.

[0050] In addition to utilizing the roller slide 7 and the guide rail 6 to improve the supporting effect on the mobile frame 3, the material tray moving device can also improve the supporting effect on the mobile frame 3 through the relative position relationship between the transverse moving bracket 4 and the longitudinal moving bracket 5. Since the transverse moving bracket 4 and the first sliding part are slidingly matched, and the longitudinal moving bracket 5 and the second sliding part are slidingly matched, the relative position relationship between the transverse moving bracket 4 and the longitudinal moving bracket 5 is also the relative sliding relationship between the first sliding part and the second sliding part.

[0051] For example, a strip-shaped pallet fixing plate 31 is provided at the bottom of the mobile frame 3; the mobile frame 3 has a first sliding portion and two second sliding portions, the first sliding portion is located in the middle of the pallet fixing plate 31 along the length direction, and the two second sliding portions are respectively located at both ends of the pallet fixing plate 31 along the length direction. Therefore, the two second sliding portions that slide with the two transverse moving brackets 4 can stably support the pallet fixing plate 31, and prevent the first sliding portion and the longitudinal moving bracket 5 from displacement in directions other than the X-axis and the Y-axis. The X-axis and the Y-axis here are respectively the same as the X-axis and the Y-axis mentioned above.

[0052] The first sliding part may include a rotating shaft 8 fixed to the tray fixing plate 31 and a ball bearing 9 sleeved on the rotating shaft 8; the rotating shaft 8 is vertically distributed and extends toward the bottom of the tray fixing plate 31, and the ball bearing 9 is sleeved on the bottom end of the rotating shaft 8. Therefore, the first sliding part and the horizontal guide groove 511 refer to the ball bearing 9 being embedded in the horizontal guide groove 511 and slidingly fitted in the horizontal guide groove 511. When the ball bearing 9 slides along the extension direction of the groove body of the horizontal guide groove 511, the ball bearing 9 rolls in contact with the groove side wall of the horizontal guide groove 511, thereby reducing the friction between the ball bearing 9 and the horizontal guide groove 511. Among them, the longitudinal movement bracket 5 includes a longitudinal movement support plate 51, a longitudinal movement slider 52 arranged at the bottom of the longitudinal movement support plate 51, and a longitudinal movement slider pad 54 arranged between the longitudinal movement support plate 51 and the longitudinal movement slider 52; the horizontal guide groove 511 is arranged on the upper surface of the aforementioned longitudinal movement support plate 51, and the longitudinal movement slider 52 is slidingly connected to the guide rail 6. Therefore, the ball bearing 9 installed on the rotating shaft 8 is embedded in the longitudinal movement support plate 51 to achieve rolling cooperation with the horizontal guide groove 511.

[0053] The second sliding portion may include a tray transverse sliding slider 32 that is slidably matched with the transverse guide rail 643 of the transverse sliding bracket 4 .

[0054] Further, the tray fixing plate 31 can be fixedly connected to two rotating shafts 8, the two rotating shafts 8 are parallel and adjacent, any one of the rotating shafts 8 is connected to a ball bearing 9, and the ball bearings 9 of the two rotating shafts 8 are both embedded in the horizontal guide groove 511. The two ball bearings 9 respectively roll in contact with the two groove side walls of the horizontal guide groove 511, and any one of the ball bearings 9 only rolls in contact with one groove side wall of the horizontal guide groove 511. In other words, the horizontal guide groove 511 has a first groove side wall and a second groove side wall that are relatively distributed, the ball bearing 9 connected to one rotating shaft 8 only rolls in contact with the first groove side wall, and the ball bearing 9 connected to the other rotating shaft 8 only rolls in contact with the second groove side wall, and the two ball bearings 9 roll in contact with each other.

[0055] The two rotating shafts 8 can be positioned and connected to the middle of the tray fixing plate through the longitudinal circular fixing plate 33. Compared with one ball bearing 9 rolling in one horizontal guide groove 511, the installation of two ball bearings 9 in the horizontal guide groove 511 is more stable and reliable, and the wear of any ball bearing 9 by the horizontal guide groove 511 is more uniform, which is more conducive to accurately controlling the movement accuracy of the moving frame 3.

[0056] In another embodiment provided by the present invention, a mounting groove for supporting the material tray 01 is provided on the top of the movable frame 3. The material tray 01 can be suspended above the tray fixing plate 31 through the aforementioned mounting groove to adapt to the material inserted into the material tray 01.

[0057] Furthermore, the mounting groove is specifically a horizontal slot for realizing the pull-out movement of the material tray 01 in the horizontal direction. The horizontal slot can not only constrain the relative position relationship between the material tray 01 and the mobile frame 3 in the horizontal direction, but also ensure that the mobile frame 3 can drive the material tray 01 to move smoothly and accurately, thereby improving the lateral movement accuracy and longitudinal movement accuracy of the material tray 01.

[0058] The material tray moving device provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
