SU63808A1 - Device for automatic sorting of glass-shaped articles by the depth of their cavity - Google Patents

Description

Devices are already known for automatically sorting products according to their sizes, provided at the points of measurement of products with indicators that close the circuits of electromagnets that control the plates that determine the path of further movement of the product after measurement. Also known are depth gauges with a probe that is movable relative to the sleeve in the axial direction, carrying a contact, for example, to close an electrical signal when the depth of the product deviates from the prescribed one.

The proposed device for automatic sorting of glass-shaped articles by the depth of their cavity, using a similar type of depth gauge, has the distinctive feature that the probe and the depth gauge sleeve are movable so that, when the depth of the cavity exceeds the normal one, the probe moves relative to the sleeve as a result of its abutment in the end of the product and, on the contrary, with the depth of the cavity smaller than the allowable size, the sleeve moved relative to the probe in

the result of the last stop in the bottom of the glass product.

In FIG. 1 is a schematic front view of the device, FIG. 2 is a kinematic diagram of the drive of the device of FIG. 1, fig. 3 is a longitudinal section through an exemplary embodiment of a depth gauge to the device of FIG. 1, and FIG. 4 and 5 explain the operation of the depth gauge device of FIG. 1 when controlling a glass-shaped product with an excessive depth of the cavity and a product with too deep a cavity.

The device has a hopper 1 (Fig. 1), designed to fill glass-shaped products. for example, hollow rivets, mechanism 2 feeding through the product and actuated by the pin 3, the chute 4 and the disk 5, feeding the product oriented in one direction to the depth gauge 8. Sleeve 6 is intended to divert products with cavity dimensions deviating from the prescribed size in depth, and sleeve 7 - for the removal of suitable products.

The device is driven by an electric motor 9 (Fig. 2). sending the rotation shaft 10, from

pulley 11 which, through flexible coupling 12, receives rotation of the pulley 3 of the feeding mechanism 2 of the hopper 1. The knee 13 of the shaft 10 is intended to be moved by the leash 14 of the pawl 15 and fed by the ratchet 16 of the disc 5. The conical gears 17-18 are designed to turn the roller 19 with the crank 20, the transfer rod 21 reciprocating movements of the slider 22 of the housing 23 of the depth gauge fixedly mounted. The slider 22 is mounted on the pin 24 (Fig. 3) with the head supported by the spring 25, which transmits the pressure to the sleeve 26, and through it to the sleeve 27, the shaft 28 of which can abut the end of the product. Inside the sleeve 27, a spindle 29 which is movable relative to it is inserted with a probe 30 at the end. The other end of the spindle 29 is provided with a finger 31, on which a spring 32 is worn, abutting with one end at the end of the spindle 29, and the other at the slider 33 with the finger 34 preventing the slider 33 from rotating around the axis of the spindle 29 and passing into the slot 35 of the sleeve 27 The sleeves 26 and 27 are slidably inserted into the tubular nipple 36 fixed in the housing 23 with the screw 37.

To prevent the sleeve 27 from turning around its axis, the finger 38, which passes through the slot 39 in the wall of the nipple 36 and is pressed by the spring 40, is inserted into the glass 41 of the nipple 36. The spring-loaded retainer 42, screwed in the sleeve 43 and screwed into the sleeve 27, is designed to interact with spindle 29 before starting the depth gauge. The spindle 29 at its end with the probe 30 is equipped with a lateral depression for the end of the switch 44, pivoting on the axis 45 of the sleeve 27.

Contacts 46-47 and 48-49 are connected in parallel to the winding of the electromagnet 50, which controls the shield at the exit of the products into the channels 6 or 7 of the device.

. The spring 32 is somewhat stronger than the spring, the latch 42, but weaker than the spring 25. The flap sleeve 7 is not

has, and the sleeve 6 is provided with a shield, controlled by an electromagnet 50 and becoming across the path of the product to the sleeve 6 with a cavity depth in the product deviating from the prescribed one.

The essence of the operation of the depth gauge is explained in FIG. 4 and 5. When checking the rivet 51 with a too deep cavity (phg. 4), the joint movement of the sleeve 27 and the pinch 29 along the rivet axis abutting on the disk 5 causes the sleeve 27 to rest against the end of the rivet 28, and the gauge 30 continues to slide into the rivet cavity with the spindle 29, turning the switch 44 and closing them contacts 47 and 46 of the electromagnet 50 of the flap of the sleeve 6, i.e., opening it to retract the unfit rivet to the sleeve 6. When the slide 22 moves away from the product, springs 25, 32 and 40 restore the initial position of the depth gauge and switch parts 44 returns to the middle position, in which the latch 42 engages the recess 29 of the spindle.

When checking the rivet 52 with an insufficient cavity depth (Fig. 5), joint movement along the rivet axis of the sleeve 27 and pin 29 with the probe 30 causes the probe to rest against the bottom of the rivet glass, as a result of which Spindle 1 29 stops, and sleeve 27 continues one is somewhat close to the end of the rivet together with the axis 45 of the switch 44. The axis of rotation of the switch is a recess on the side of the spindle 29. The switch 44 leaves the middle position, closing the contacts 48-49 of the electromagnet 50, i.e. opening the flap of the sleeve 6.

The design of the hopper, the disk 5, the shield of the sleeve 6 and a number of other parts of the device may be different, but this design does not affect the essence of the invention.

Subject invention

A device for automatic sorting of glass-shaped articles according to the depth of their cavity using an indicator depth gauge, the arrow of which, when the dimensions deviate from the allowable ones, closes one of the circuits with electromagnets serving to open the corresponding

shield on the path of the part, characterized in that the probe 30 and the sleeve 27 of the indicator depth gauge are movable

In order to exceed the depth of the product cavity of a normal size, the probe 30 would move relative to the sleeve 27 as a result of the abutment of the latter into the end of the product and, conversely, if the cavity depth was smaller than the allowable size, the sleeve 27 would move relative to the probe 30 as a result of the stop last in the bottom of the glass product.
