Implementation of the utility model.

The dispenser for packing bulk products contains fixed lower 1 and upper 2 parts of the body (see Fig. 1-4), between which the gate 3 is movably mounted in the longitudinal plane.

In the lower part of the body 1 of the dispenser, an outlet 4 is made, and in the upper part of the body 2 of the dispenser, loading holes 5 are made. In the gate 3, measured volumes 6 are made in the form of through holes, the diameters of which are equal to the diameters of the loading holes 5 and less than the diameter of the outlet 4.

The distance between the centers of the measured volumes 6 is half the distance between the centers of the loading holes 5, and the outlet 4 is located in the center between the loading holes 5 with the possibility of alternate alignment with one of the measured volumes 6 when the gate 3 is moved from one extreme position to another or other In other words, the distances between the loading holes 5 and the outlet 4 are equal to the stroke of the gate 3.

The loading holes 6 in the upper part of the housing 2 of the dispenser are made with the possibility of connecting to them a container with a dosed product (not shown in the figures).

Flanges 7 are mounted to the ends of the dispenser (see Fig. 5) with holes made in them for mounting through the said holes to the ends of the gate 3 of the rods of the left 8 and right 9 pneumatic cylinders mounted, respectively, on the left and right of the lower part of the dispenser housing 1. Said rods of pneumatic cylinders 8, 9 are in interaction with the end surfaces of the gate 3.

On one of the edges of the gate 3, on one side and the other, there are bars 15 directed downwards through a rectangular hole made in the lower part of the body 1. The rectangular hole in the fixed lower part of the body 1 is made with the possibility of ensuring the movement of the bars 15 in it together with the gate 3. On one of the straps 15, a pneumatic cylinder for gripping the packaging material 10 is mounted, the rod of which is directed towards the second strap 15, and in the second strap 15, an adjustable stop 11 is mounted, made in the form of a screw, the end of the rod of which is directed towards the rod of the pneumatic cylinder for gripping the packaging material 10 and is made consonant with him. Mentioned stop 11 and pneumatic cylinder 10 are made with the possibility of placing between them the upper edges of the packaging material to connect them to each other. Stop 11 is equipped with a lock nut 16.

A guide element 17 is mounted to the lower part of the body 1, made in the form of a rectangular plate, provided with an outlet 4, aligned with the outlet 4, made in the said part of the body 1. Along the guide element 17 along its entire length, on both sides of the outlet 4 vertically slots 18 are made with the possibility of accommodating the upper edges of the packaging material in them, with two grooves for the packaging material and an opening for the output of products throughout.

The dispenser for packing bulk products is equipped with a control unit 12 (see Fig. 6) and two position sensors 13 mounted on pneumatic cylinders 8, 9 and connected to the control unit 12.

The outputs of the control unit 12 are connected to the inputs of the electromagnetic actuators of the pneumatic distributors 14, the outputs of which, in turn, are connected to the piston cavities of the pneumatic cylinders 8-10.

The dispenser for packing bulk products works as follows.

Initially, the edges of the packaging material are placed in the slots 18 of the guide element 17, at the exit of which the connected edges of the mentioned packaging material are placed between the rod of the pneumatic cylinder for gripping the packaging material 10 and the stop 11.

The dispenser for packing bulk products allows you to obtain the required dose of bulk material supplied to the packaging material by multiple dosing of a single dose. In the case of receiving a dose by single dosing, only one hopper is used.

With a single dosing, the gate 3 in the initial position is in the extreme right position and one of the measured volumes 6 is located under the loading opening 5, to which the hopper is connected. In this position, the dosed bulk product is supplied from the hopper through the loading opening 5 into the measured volume 6.

The position of the gate 3 is ensured by supplying air pressure to the cavity of the left pneumatic cylinder 8 through the corresponding distributor 14. At the same time, pressure is applied to the rod cavity of the pneumatic cylinder for capturing the packaging material 10 to retract its rod and release the packaging material.

When a signal is received from the control unit 12 to turn off the pneumatic distributor 14 connected to the left pneumatic cylinder 8 and turn on the pneumatic distributor 14 responsible for supplying compressed air to the piston cavity of the right pneumatic cylinder 9, the gate 3 moves to the left side.

When the gate 3 is moved to the extreme left position, the measured volume 6 of the gate 3 is located above the outlet 4 of the lower part of the body 1 and its emptying begins, while from the position sensor 13 located on the left pneumatic cylinder 8, a signal is sent to the control unit 12, which initiates the countdown of the time allotted for packaging, that is, the entry of the bulk product into the container. In addition, a signal is sent from the control unit 12 to the pneumatic distributor 14, which supplies compressed air to the piston cavity of the pneumatic cylinder for gripping the packaging material 10 and the packaging material is captured by clamping it between the rod of the mentioned pneumatic cylinder 10 and the stop 11. After a predetermined period of time there is a signal from the control unit 12 to the pneumatic distributor 14, which provides compressed air to the piston cavity of the left pneumatic cylinder 8. The gate 3 moves to the extreme right position.

The signal from the position sensor 13, located on the right pneumatic cylinder 9, enters the control unit 12, which sends a signal to turn off the pneumatic distributor 14 connected to the pneumatic cylinder of the gripper of the packaging material 10, which stops the supply of compressed air to the piston cavity of the mentioned pneumatic cylinder 10 and the packaging material is released. In addition, the control unit 12 initiates a signal after filling the measured volume 6 on the pneumatic distributor 14 of the right pneumatic cylinder 9, and the movement of the gate 3 to the left side begins.

When the gate 3 moves to the left side, the packaging material is stationary, and when the gate 3 moves to the right, the packaging material is pulled along the slots 18 in the guide element 17 simultaneously with the movement of the gate 3 using a pneumatic cylinder for gripping the packaging material 10, which ensures that the edges of the mentioned packaging material are pressed between the rod of said pneumatic cylinder 10 and stop 11. In this case, the time of movement of the gate 3 increases, and the speed of movement of the bulk product decreases, thereby reducing the probability of loss of the bulk product.

When receiving a dose by multiple dosing, the operation of the dispenser begins from the position when the gate 3 is in the leftmost position. In the initial position, through the pneumatic distributor 14, connected to the pneumatic cylinder of the capture of the packaging material 10, pressure is applied to the piston cavity of the said pneumatic cylinder 10, and the packaging material is captured.

When a signal is received from the control unit 12 about filling the left measured volume 6 and the end of the packaging process, a signal is sent to the pneumatic distributor 14, which turns on the supply of compressed air to the piston cavity of the pneumatic cylinder for capturing the packaging material 10, and the movement of the gate 3 begins to the right side with simultaneous by pulling the packaging material through the slots 18 of the guide element 17 by one step. At the same time, the movement of the filled measured volume 6 occurs. When the leading edge of the measured volume 6 reaches the leading edge of the outlet 4, the emptying of the measured volume 6 begins and the minimum possible fall time of the bulk product particles is determined from the expression:

t = 2H/g,

where H is the height of the outlet 4, g is the free fall acceleration.

In this case, the leading edge of the filled container or package reaches the leading edge of the outlet 4 before the leading edge of the measured volume 6. When the gate 3 takes its extreme right position, the signal from the position sensor 13, mounted to the right of the gate 3, enters the control unit 12 and after a period of time t from the control unit 12 a signal is sent to the pneumatic distributor 14 connected to the right pneumatic cylinder 9 and the piston of the said cylinder 9 will start moving to the left, while after receiving a signal from the mentioned position sensor 13, the control unit 12 sends a signal to the pneumatic distributor 14 connected to pneumatic cylinder for gripping the packaging material 10 for retracting the rod and releasing the packaging material from the grip. The gate 3 shifts to the left and the emptying of the right measuring volume 6 begins. When the position sensor 13, mounted to the left of the gate 3, is triggered, the control unit 12 sends a signal to the pneumatic distributor 14, which turns on the pressure supply to the piston cavity of the left pneumatic cylinder 8. Before this, the control unit 12 turns off pneumatic distributor 14 of the pneumatic cylinder of the capture of the packaging material 10 and the packaging material is captured for its further pulling. After actuation of the pneumatic distributor 14, connected to the left pneumatic cylinder 8, the packaging material is pulled with a nominal dose equal to two single doses.

With odd doses of bulk product, the initial position of the gate 3 is on the right side, with even doses - on the left side.

Thus, due to the use in the design of the dispenser of a pneumatic cylinder for gripping the packaging material 10 and coaxially located stop 11, which ensure the capture of the packaging material, the edges of which pass in the slots 18 of the guide element 17 and thereby ensure the possibility of pulling the packaging material along with the movement of the gate 3 from one extreme position to another under the control of the control unit 12, which provides synchronization of the pneumatic elements of the dispenser, the technical result is achieved - providing the possibility of creating a simple and reliable dispenser for dosing and packaging bulk products with simultaneous broach of the packaging material.
