Description

one

The invention relates to packaging equipment, namely, devices for the preservation and packaging of the same type of items.

Devices for the preservation and packaging of objects of the same type are known, comprising a feeder with a mechanism for moving objects, a device for preserving, a table pivoting around a horizontal axis for orientation of objects and a packaging mechanism.

However, the known devices provide preservation and packaging of the same type of parts without their additional orientation.

The proposed device provides orientation of adjacent objects, such as hacksaw blades, with teeth in opposite directions.

This is achieved by the fact that the rotary table is equipped with a gate valve controlled by sensors made in the form of spring-loaded rods carrying rotary probes with teeth that serve to interact with the ends of the objects.

In order to increase the reliability of operation, the probes' teeth are arranged at an angle to the direction of movement of objects and fixed with the help of spring-loaded shoes having inclined planes. In addition, to avoid repeated coupling of the probe teeth to the teeth of the same

Spring-cut rods of the hacksaw blade are interconnected with pivoting levers controlled by a gate valve and provided with retainers.

FIG. 1 shows the kinematic scheme of the device proposed; in fig. 2-rotary table of the device and sensors for monitoring the position of the product; in fig. 3 is a section along A-A in FIG. 2

The proposed device comprises a feeder 1 with a mechanism for moving the hacksaw blades 2, made in the form of rotary grippers 3, kinematically associated with a roller conveyor 4, equipped with drive rollers 5 installed in pairs.

The roller conveyor 4 is directly adjacent to the rotary table 6, the slit-like groove 7 of which is blocked by a gate valve 8 controlled by a spring-loaded bracket 9 and the rotary lever 10, the free end of which interacts with the face cam 11 mounted on the single-turn clutch 12 controlled by the electromagnet 13.

On the roller conveyor 4, perpendicular to the ends of the hacksaw blade 2, sensors 14 and 15 are installed to control the position of the product, made in the form of the pods of the inward rods 16 and 17, at the ends of which rotary probes 18 and 19 are fixed, whose teeth are angled to the ends of the objects and fixed using spring-loaded shoes 20 and 21, the inclined planes of which interact with probes 18 and 19. At the second ends of the spring-loaded rods 16 and 17, flags 22 are inserted into the grooves of the inductive sensors 23 and 24, and the rods 16 and 17 are fitted with latches 25 and 26 and interact with the pivoting arms 27 and 28, controlled by a spring-loaded bracket 9 of the slide valve 8. Under the slit-like groove 7 of the rotary table 6, a receiving tray 29 of the bundle of hacksaw blades 2 equipped with retainers 30 and 31 and a pusher 32 is placed. The receiving tray 29 adjoins the stepping conveyor 33, carrying a complete stack of products and equipped with a bundling mechanism 34, fed to the pivoting arms 35 of the conservation device 36 and the wrapping wrapper mechanism 37, kinematically associated with the mechanism for moving the saw blades. The device works as follows. The hacksaw blades 2 from the feeder 1 are individually delivered by the swivel grips 3. onto the roller conveyor 4 and are mounted on the edge between the drive rollers 5. The latter alternately grips the hacksaw blades and push them between the sensors 14 and 15 of the control position of the product. Rotary probes 18 and 19, mounted on spring-loaded rods 16 and 17, interact with the ends of the hacksaw blade 2. At the same time, depending on the orientation of blade 2 on the roller conveyor, 4 teeth up or teeth down, one of the probes 18 or 19, which interact with the smooth end of the hacksaw blade 2, is rotated by a slight angle, the corresponding shoe 20 or 21 is raised, while the spring-loaded bar of this probe remains stationary. The second probe, which interacts with the teeth of the hacksaw blade 2, engages with them and rotates, simultaneously moving the corresponding spring-loaded rod, the flag 22 of which, moving in the groove of one of the inductive sensors 23, 24, generates in the latter a signal recorded by the memory device of the system automatic control (not shown) of issuing a hacksaw in the receiving tray 29 of the bundle bundle. At the end of the movement, the corresponding spring-loaded rod 16 or 17 is fixed by a lock in the extreme upper position and thereby disengages the rotary probe from the teeth of the blades 2. Further, after pre-controlling the orientation of the hacksaw blade 2 on a roller conveyor 4, the drive rollers 5 feed the blade into the slotted groove 7 of the turntable 6 of reorienting the blades. If the teeth of the blade fed into the slot-like groove 7 are oriented in the opposite direction with respect to the tooth m. The previously laid hacksaw 2 into the receiving tray 29, the memory device receives the command to activate the end cam 11, which interacts with the pivoting arm 10, which moves the spring-loaded bracket 9, and the last gate valve 8. The saw blade 2 falls out of the slot-like groove 7 and enters the receiving tray 29, in which the pushers 32 are fed up to the stop into the plane of the previously filed saw and the retainer is fixed mi 30 and 31. If the next hacksaw enters from the roller conveyor 4 into a slot-like groove 7 teeth, oriented in the same direction as the tooth of the hacksaw previously placed in the receiving tray 29, which is fixed by the memory of the automatic control system by the commands of the sensors 14 and 15 , a memory is received from the memory device by the electromagnet 13, which includes a one-turn clutch 12, which rotates table 6 by 180 ° through a gear drive, thus realizing the re-orientation of the HEADER relative to the previously laid one. Then, the end cam 11, interacting with the pivot arm 11, with the help of a spring-loaded bracket 9 shifts the gate valve 8, and the hacksaw blade 2, as in the previous case, enters the receiving tray 29. Thus, regardless of the arrangement of the teeth of the next hacksaw 2 supplied but the roller conveyor 4, each of the hacksaws, according to the commands of the sensors 14 and 15, and the memory of the program control system, will be reoriented by the teeth in the opposite direction relative to the previously laid hacksaw into the receiving tray 29. Pos When each next workpiece is dispensed into the slot-like groove 7 of the turntable 6, the spring-loaded rods 16 and 17 of the sensors 14 and 15, which interact with the teeth of the handsaw, are lifted and fixed in the off position by the latches 25 or 26. The preparation of the sensors 14 and 15 to control the orientation of the next hacksaw carried out levers 27 and 28 interacting with spring-loaded rods 16 and 17 when the spring-loaded bracket 9 is moved at the moment of issuing the previous hacksaw blade 2 from the slot-like groove 7 to the receiving tray 29. After completing the package bundle In the receiving tray 29, the number of which is controlled by a counting device (not shown in the drawings), the bundle of cloths by the pusher 32 is transferred to the loading position of the stepping conveyor 33, in which the bundle is wrapped using the mechanism 34. Further, the pack of hacksaw blades from the transporter 33 enters the receiver bindings of the levers 35 of the device 36 and, after conservation, is transferred to the wrapping mechanism 7, from where it enters the packaging.
