Description

Technical Field

[0001] The utility model relates to a capsule machine, and more particularly to a bar group turning and transferring device. Background Art

[0002] A capsule machine is a device for producing hollow hard capsules, and the forming of capsules is achieved through multiple needles on a bar group (or called a needle die bar). As Figure 9 shown, a bar group 100 is composed of multiple needles 102 riveted on a rectangular strip 101, which can improve production efficiency and facilitate circular operation on the production line.

[0003] During the production process of capsules, the bar group will undergo a process of changing from longitudinal movement to lateral flipping, which is called dropping the bar. The common dropping process mainly relies on the self-weight of the bar group to achieve, so that the bar group changes from a side-mounted state (the needles are horizontal) to a lying state (the needles are vertically downward). As Figure 10 shown, the transmission direction of the production line is the X direction. Combining Figure 11 , the bar group 100 moves along the Y direction on both sides of the transverse guide rail 103 and enters the guide groove 104. When the bar group 100 moves to a specified position, the braking assembly 105 is activated to stop the further movement of the bar group 100. After stopping the movement, the bar group 100 freely falls by its own gravity, and the stationary slideway 106 below catches and supports the dropped bar group 100. Next, the motor 107 is activated, and the first rack plate 108 and the second rack plate 109 are driven to move in the X direction through the mechanical transmission mode of gears and racks. The movement of the rack plates 108 and 109 drives the bar group 100 to disengage from the slideway 106 and transfer it to the next process of the production line. When the bar group 100 freely flips onto the slideway 106, it may rebound due to the impact force, resulting in an uncontrollable position of the bar group 100 on the slideway 106. Two bar groups 100 are likely to be stuck together, and even the bar group 100 may fall off the working station, thus affecting its precise positioning on the production line and possibly leading to production interruption or product quality problems.

[0027] The following will, in conjunction with the accompanying drawings, give the preferred embodiments of the present utility model and describe them in detail.

[0028] As Figure 1 shown, the bar group turning and transferring device according to a preferred embodiment of the present utility model includes a front plate 1, a rear plate 2, a turning mechanism 3 and a bar moving mechanism 4. Among them, the front plate 1 and the rear plate 2 extend parallel to each other at intervals along the transmission direction of the production line. The turning mechanism 3 and a bar moving mechanism 4 respectively straddle and are installed on the front plate 1 and the rear plate 2. Figure 2 The bar group 100 in the side-mounted state shown is turned to Figure 3 the lying state shown by the turning mechanism 3 and then transferred by a bar moving mechanism 4. The left and right sides of the turning mechanism 3 are respectively formed as the body side A and the cap side B, which are respectively used for the processing of the capsule body and the capsule cap. Thus, the body side slideway 5 is installed on the front plate 1 and the rear plate 2 on the left side of the turning mechanism 3, and the cap side slideway 6 is installed on the front plate 1 and the rear plate 2 on the right side of the turning mechanism 3, which are respectively used to receive the bar groups 100 on the body side A and the cap side B from a bar moving mechanism 4 and transfer them to the next process of the production line.

[0029] As Figure 1 and Figure 4 shown, the turning mechanism 3 includes a base 31, a slide rail frame 32, a first driving device 33, a driving rod 34 and an articulated arm 35. Among them, the base 31 straddles and is installed on the front plate 1 and the rear plate 2. The slide rail frame 32 is articulated with the base 31 through a first articulated shaft 32a. The bar group 100 can be slidably installed on the slide rail frame 32 along the Y direction. The first driving device 33 installed on the base 31 is connected to one end of the driving rod 34 extending in the Z direction. The other end of the driving rod 34 is articulated with one end of the articulated arm 35. The other end of the articulated arm 35 is articulated with the slide rail frame 32 through a second articulated shaft 35a to drive the rotation of the articulated arm 35 and the slide rail frame 32 through the first driving device 33. Specifically, when the driving rod 34 moves upward, both articulated arms 35 will move upward, and at the same time, the articulated arm 35 rotates, and the slide rail frame 32 rotates accordingly, so that the bar group 100 on the slide rail frame 32 is turned from the side-mounted state to the lying state. Since the turning of the bar group 100 is realized by following the rotation of the slide rail frame 32, and the trajectory of the slide rail frame 32 is determined, the dropping position of the bar group 100 can be controlled.

[0030] As Figure 5 shown, a bar moving mechanism 4 includes a second driving device 41 and a main driving shaft 42.

[0032] As Figure 6 shown, the body side driving wheel assembly 44 includes a sleeve 441, a driving wheel shaft 442, a body side driving pulley 443 and a body side cylindrical gear 444.

[0033] As Figure 5 shown, a bar moving mechanism 4 further includes a cap side driving pulley 47 and a cap side synchronous belt 48. Among them, the cap side driving pulley 47 is fixed on the main drive shaft 42 and rotates synchronously with the rotation of the main drive shaft 42.

[0034] As Figure 7 shown, the driven wheel assembly 46 includes a driven wheel shaft 461 and a driven pulley 462. Among them, the driven wheel shaft 461 is fixedly installed on the front plate 1 and the rear plate 2 (see Figure 1 ), and the driven pulley 462 is rotatably installed on the driven wheel shaft 461 through a bearing 462a.

[0035] AsFigure 5 As shown, a rod moving mechanism 4 further includes a tensioning assembly 49 which is arranged below the synchronous belts 45, 48 to adjust the tension of the synchronous belts 45, 48, ensuring good contact between the synchronous belts 45, 48 and the belt pulleys 443, 462, 47. As Figure 8 shown, the tensioning assembly 49 includes a mounting plate 491 and a tensioning pulley 492.

The lubricating plate 51 is fixedly installed on the support plate 50 and is arranged between the support plate 50 and the synchronous belts 45, 48 to enable the synchronous belts 45, 48 to slide thereon.

[0037] The working mode of the rod group turning and transferring device according to the present invention will be briefly described below. First, the rod group 100 enters the turning mechanism 3 in a side-mounted state. Then the turning mechanism 3 works to turn the rod group 100 by about 90 degrees, changing it from a side-mounted state to a lying state. The turned rod group 100 contacts the synchronous belts 45, 48, and the synchronous belts 45, 48 respectively transfer the turned rod group 100 on the body side A and the cap side B to the chutes 5, 6 through friction. After the turning and conveying of one rod group 100 are completed, the turning mechanism 3 returns to its original position and waits for the next rod group 100 to enter.

[0038] It should be understood that the rod group 100 in the specific production process can be seven-rod movement, nine-rod movement or twelve-rod movement, etc. After reaching the required number of rods one by one through the one-rod moving mechanism 4 of the present invention, the chutes 5, 6 can move multiple rod groups 100 together. The one-rod moving mechanism 4 according to the present invention is cheap in cost, convenient to disassemble, small in occupied space and easy to install.

[0039] The one-rod moving mechanism 4 according to the present invention picks up the rod group 100 from the previous process and sends it to the next process by means of active conveying through the synchronous belts 45, 48. The speed of the synchronous belts 45, 48 can be adjusted according to the speed of the previous process, that is, the speed is controllable, and it can meet any required speed requirements of the capsule production equipment, and the on-site use effect is good.

[0040] It should be understood that the drive mechanisms on the front and rear sides of the one-rod moving mechanism 4 according to the present invention are symmetrically arranged, and the synchronous belt method adopted can also be replaced by a conveying medium such as a chain to complete the rod receiving action.
