Description

Technical Field

[0001] The present invention relates to an automatic linear dropping pump device, and in particular to an automatic linear dropping pump device for filling equipment. Background Art

[0002] In a filling production line, the capped bottles need to be sealed by screwing on the caps. For containers with a suction pump head (also known as a pump head cover), before the capping machine caps the bottle, since a pump head rod is connected under the suction pump head, it is difficult for existing filling equipment to align the suction pump head with the bottle mouth and place it in, and basically only manual placement can be used. Such a method affects the efficiency and increases the cost.

[0003] The applicant of the present invention has developed an automatic pump head dropping device, which consists of a pump head feeding device, a bottle feeding device, and a pump head hooking device. The bottle feeding device includes a bottle feeding star wheel for driving the bottle body to move from the bottle feeding direction to the bottle discharging direction. Due to the use of a circular bottle feeding star wheel, the above automatic pump head dropping device has a complex structure, a high manufacturing cost, and limited applicability. Summary of the Invention

[0004] For this reason, the technical problem to be solved by the present invention is to provide an automatic dropping pump device with a simple structure and strong applicability.

[0005] For this reason, the present invention provides an automatic linear dropping pump device, including a pump head feeding device for conveying the pump head, a bottle feeding device for conveying the bottle body, and a pump head hooking device for hooking the pump head conveyed by the pump head feeding device. The pump head hooking device is located above the bottle feeding device, so that the hooked pump head falls along a predetermined path and is sent into the bottle body. The pump head hooking device is characterized in that it includes: two sets of parallel rotary tracks, each set of rotary tracks including a straight section and a curved section. A plurality of sets of vertical guide rods are fixed around the rotary tracks, and the vertical guide rods can rotate on the rotary tracks. Hooks for hooking the pump head are arranged on each of the vertical guide rods, and the hooks can move up and down along their respective vertical guide rods. Guide wheels are arranged on the trailing edges of the hooks; a lower slope straight track and an upper slope straight track are respectively arranged between the upper and lower rotary tracks, wherein the lower slope straight track is located on the front side of the rotary track facing the bottle feeding device, and the lower slope straight track is located on the back side of the rotary track away from the bottle feeding device. The guide wheels can move down along the lower slope straight track, so that the hooks move down along the vertical guide rods, and the guide wheels can move up along the upper slope straight track, so that the hooks move up along the vertical guide rods.

[0006] Preferably, each set of rotary tracks is driven by two sprockets to rotate the chain.

[0007] Preferably, the vertical guide rod is configured as a ball spline shaft, and the hook is connected to the outer sleeve of the ball spline shaft.

[0008] Preferably, a pulley swing rod guide is provided on the straight section of the front surface of the upper rotary track. The upper end of the vertical guide rod is fixed in the pulley swing rod. A torsion spring is provided on the pulley swing rod. When the vertical guide rod travels to the straight section, the pulley swing rod is restricted by the pulley swing rod guide and swings in the hooking direction, driving the vertical guide rod to rotate for hooking the pump head by the hook. When the pulley swing rod reaches the end of the pulley swing rod guide, the pulley swing rod disengages from the pulley swing rod guide and drives the vertical guide rod to rotate under the elastic force of the torsion spring, causing the hook to deflect in the direction of disengaging from the pump head.

[0009] Preferably, a plurality of funnels are provided on the lower rotary track. The funnels are located below the hook and are used to guide the suction pipe of the pump head into the bottle body. The number and position of the funnels correspond to the vertical guide rod. Each of the funnels is composed of two movable half pieces.

[0010] Preferably, the two half pieces of the funnel are connected to a pair of meshing shaft gears, and a swing pulley is provided at the bottom of one of the shaft gears. A striker is provided at the end of the straight section of the lower rotary track. When the striker hits the swing pulley and causes it to rotate, it drives the shaft gear to rotate and separates the two half pieces.

[0011] Preferably, the two half pieces are separated by more than 120°.

[0012] Preferably, the bottle feeding device is a screw. The pitch of each feed of the screw is equal to the interval distance of the vertical guide rod, and they maintain synchronous movement.

[0013] The beneficial effects of the present invention are as follows.

[0024] Refer to Figures 1 to 4 , the automatic linear dropping pump device according to an embodiment of the present invention includes a pump head feeding device 1, a bottle feeding device 2, and a pump head engaging device 3.

[0025] The pump head feeding device 1 transports the pump head B to be screwed onto the bottle body C to the outlet 10. The pump head engaging device 3 engages the pump head B at the outlet 10. The bottle feeding device 2 is located below the pump head engaging device 3, and the pump head B engaged by the pump head engaging device 3 can fall along a predetermined path and be fed into the bottle body C.

[0026] The bottle feeding device 2 of the present invention adopts the manner of a screw rod 20, wherein the pitch of each feed of the screw rod 20 is equal to the interval distance of the vertical guide rod 32 (described below) of the pump head engaging device 3, and they are also synchronous during movement. In this way, each engaged pump head B corresponds one-to-one with the transported bottle body C.

[0027] The improvement of the present invention lies in the pump head engaging device 3, which includes: two sets of parallel rotary tracks 30 up and down. Each set of rotary tracks 30 is driven by two sprockets 31 to rotate the chain. However, the present invention is not limited thereto, and other transmission methods can also be used to make the rotary tracks 30 rotate. Each set of rotary tracks 30 includes a straight section and a curved section. The front and rear straight sections are working areas, the front straight section makes a descending downhill movement, and the rear straight section is the return journey making an ascending uphill movement.

[0028] Multiple sets of vertical guide rods 32 are fixed on the periphery of the rotary tracks 30. In one embodiment, there are nine sets, and it can also be other quantities. For the sake of clarity, only one set of vertical guide rods 32 is shown in the drawings.

[0029] A hook 33 for hooking the pump head B is provided on each of the vertical guide rods 32. In the present embodiment, the vertical guide rod 32 is configured as a ball spline shaft, but other configurations may also be used. The hook 33 is mounted on an outer sleeve 320 of the ball spline shaft.

[0030] The hook 33 can move up and down along the respective ball spline shafts, i.e., the vertical guide rod 32, by means of the outer sleeve 320. A guide wheel 34 is arranged on the rear edge of the hook 33. A lower slope linear track 35a and an upper slope linear track 35b are arranged between the upper and lower rotary tracks 30, respectively. The lower slope linear track 35a is located at the front of the rotary track 30 close to the bottle feeding device 2, and the upper slope linear track 35b is located at the back of the rotary track 30 away from the bottle feeding device 2. The guide wheel 34 can move down along the lower slope linear track 35a, so that the hook 33 moves down along the vertical guide rod 32, and the guide wheel 34 can move up along the upper slope linear track 35b, so that the hook 33 moves up along the vertical guide rod 32.

[0031] When the guide wheel 34 moves downward along the downward slope linear track 35 a and the pull hook 33 moves downward along the vertical guide rod 32 , the pump head B falls into the bottle body C synchronously conveyed by the bottle feeding device 2 .

[0032] The hook 33 is connected to the outer sleeve 320 of the ball spline shaft, and the ball spline shaft 32 is fixed on the upper and lower rotating tracks 30 and rotates with the chain. The rotation of the hook 33 is achieved by the pulley swing rod 321 at the upper end of the ball spline shaft 32 driven by the power of the torsion spring 322.

[0033] like Figures 5 - 8 As shown, the upper end of the ball spline shaft 32 is fixed in the pulley swing rod 321, and the pulley swing rod 321 is provided with a torsion spring 322. The pulley swing rod 321 moves closely on the pulley swing rod guide rail 323 outside the upper rotary track 30 under the elastic force of the torsion spring 322. The pulley swing rod guide rail 323 is only arranged in the straight section of the upper rotary track 30. When the pulley swing rod 321 enters the pulley swing rod guide rail 323, the pulley swing rod 321 is restricted by the pulley swing rod guide rail 323 and swings in the hooking direction, driving the ball spline shaft 32 to rotate, and the hook 33 hooks a pump head B at the outlet of the pump head delivery device 1.

[0034] When the pulley swing rod 321 reaches the end of the pulley swing rod guide rail 323, the pulley swing rod 321 loses support because it is separated from the guide rail 323. Under the elastic force of the torsion spring 322, the ball spline shaft 32 rotates, driving the hook 33 to deflect and swing and unhook from the pump head B. The pump head B loses the support of the hook 33 and falls to the funnel 40 below under the action of gravity.

[0035] Combined with reference Figure 1, a plurality of funnels 40 are connected to the lower slewing track 30. The funnels 40 are located below the hook 33 and are used to guide the suction pipe of the pump head B into the bottle body C. The number and positions of the funnels 40 correspond to the vertical guide rods 32, for example, there are nine. The funnel 40 is composed of two half pieces. When used to guide the pump head B, the two half pieces are combined to form the funnel 40.

[0036] A swinging pulley 41 is provided at the bottom of the funnel 40, and a striking block 42 is provided on the lower slewing track 30. When the funnel 40 travels to the position of the striking block 42, under the action of the striking block 42, the two half pieces of the funnel 40 rotate outward. The rotating shafts connected by the two half pieces are a pair of meshing funnel shaft gears 43, so these two funnel shaft gears 43 are symmetrically separated under the action of the striking block 42. Preferably, the two half pieces are separated by more than 120 degrees. At this time, the pump head B loses the support of the funnel 40 and directly drops onto the bottle mouth. The position of the striking block 42 is set at the end of the straight section of the lower slewing track, preferably after the end of the pulley swing rod guide 323. In this way, the hook 33 is first disengaged from the pump head B, and then the two half pieces of the funnel 40 are separated.

[0037] The hook 33 that is decoupled from the pump head B and the separated funnel 40 continue to rotate synchronously along the slewing track to the back to perform the next cycle of actions. When the hook 33 travels to the upper ramp straight track 35b, the guide wheel 34 can travel upward along the upper ramp straight track 35b, so that the hook 33 moves upward along the vertical guide rod 32 to prepare for the next action of hooking the pump head B, completing one working cycle.

[0038] The pump head B and the bottle body C then run linearly to the bottle clamping belt device 50 for subsequent capping actions.

[0039] Refer again to Figures 1 - 4 , the bottle clamping belt device 50 is composed of two groups of synchronous bottle clamping belts (not shown), and the whole device is fixed on a square column. The bottle clamping belt device 50 is adjusted by a height adjustment device 51, so that corresponding adjustments can be made according to the size and height of the bottle. A rubber strip bracket 53 is provided on the outer side of the bottle clamping belt for setting a rubber strip (not shown). One side of the rubber strip bracket 53 is fixed to a suspension bracket of the bottle clamping belt and can be adjusted according to the height and size of the bottle cap. Since the bottle is firmly clamped between the two belts, the outer side of the bottle cap just makes a rotational relative movement by rubbing against the rubber strip. As the bottle advances, the bottle cap is rubbed and rotated by the rubber strip to be tightened, so as to achieve the purpose of pre-tightening the cap.

[0040] The height adjustment device 51 suspends the entire bottle clamping belt device 50 on the column through a hand-cranked lead screw 510 and a linear platform via a cross arm, enabling vertical adjustment. Meanwhile, there is a set of linear slides on the cross arm. By using a left-right threaded lead screw, the suspension bracket 52 on the bottle clamping belt can be separated and combined left and right under the action of the left-right threaded lead screw to adjust the distance between the bottle clamping belts.

[0041] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the existing technology should be within the protection scope determined by the claims.
